Political apologies have been argued to contribute to reconciliation among groups and nations but their efficacy has also been questioned. This paper examines the acceptance of political apologies, their content and the protagonists in the victim nation, the perpetrator nation and their subgroups. Guided by studies on the structure of apologies, it distinguishes 10 features of apologies, seven of which concern their content and three of their protagonists. Following the analysis of apology statements by Japan to South Korea, the paper further breaks these features (factors) down into 32 elements (levels). The acceptance of around 70,000 possible apology combinations is examined in a randomized conjoint experiment, which was embedded in online quota‐based surveys in Japan (n = 2700) and South Korea (n = 3000). The analysis reveals that the content of apologies matters, protagonists matter more than content and some subgroups matter more than protagonists. The subgroup analysis showed that some within‐country differences are larger than cross‐country differences, which challenges the SIT. Apology statements that would be acceptable in both nations are summarised. [ABSTRACT FROM AUTHOR]

Legal psychology is field of research which seeks to bring evidence-based practice to the vital work of the criminal justice system. This research is increasingly being conducted and its findings applied around the world. However, worldwide legal systems and their processes can vary greatly. In the current paper, we summarise discussions between legal psychology academics and criminal justice practitioners from Japan. Together, we examine how practices in the Japanese criminal justice system interact with the international evidence base for psychologically-informed 'best practice' approaches. Our discussion targets areas of popular study in legal psychology, focusing on concealed crime knowledge detection, line up identification procedures, and investigative interviewing of witnesses, suspects, and victims. Each section features a description of current Japanese practice, followed by a review of the current state of the relevant academic legal psychological literature. We then connect this practice and research synergy to a reflection with suggestions for future research. Taken together, our paper acts as a conduit to incentivise more research and practice collaboration for Japanese and non-Japanese audiences and presents opportunities for collective international legal psychology.

• Human resources development aided the developing space program of the Philippines. • Most of the selected personnel for training came from the academia. • Trainees taken from the industry followed later to support the push for space. • Most of trained personnel opted to stay in the country to support the space program. The Philippines has experienced a shift of interest in space technology development and utilization over the past decade, culminating with the establishment of its national space agency in 2019. In cooperation with different universities in Japan, the Philippines successfully developed and launched two microsatellites, DIWATA-1 and DIWATA-2, and six nanosatellites, MAYA-1 to MAYA-6. By sending personnel to Japan and other space-faring countries, the country was able to rapidly ramp up its satellite development and utilization capabilities. In this paper, we examine and evaluate the complex human resources development efforts conducted by the country to support the creation of a local space ecosystem and ensure its long-term sustainability. Through a careful review, we identify how many people benefited from training programs, studies abroad or other forms of capacity building, and how these skilled individuals were retained in the budding Filipino space sector. Precisely, we looked at the backgrounds of the different people trained by the country, what type of training they received (funding, location, and duration), and how they are supporting the local space ecosystem at the time of writing this paper.

Based on Realism theory, this paper provides an explanation of the importance of power in International Relations, by analyzing the behavior of China and Japan in the East Asian region, and also the behavior of the United States of America towards them as the dominant superpower under the current international system. It answers the problem of the transfer of power from the West to the East, and in return supports the assumption that the Great Powers seek to possess relative power as much as possible. The paper also emphasizes that the State should not undermine or renounce its offensive power, as with Japan, because that will put it in front of a dilemma of the growing the power of neighboring States that seek to achieve regional hegemony, such as China. Therefore, all of these transformations show that international relations are a complex field and should not be reduced to a specific ideal field. [ABSTRACT FROM AUTHOR]

The maritime route connecting the Chinese continent and the Japanese archipelago facilitated a significant exchange of commercial goods and sociocultural knowledge throughout the Southern Song dynasty. Within this context, Japanese pilgrim monks traveling along this route acted as key conduits for the transmission of Buddhist teachings. Their journeys profoundly influenced the establishment and development of new Buddhist monasteries in Japan. Focusing on biographical accounts that portray the experiences of these pilgrim monks during their twelfth- and thirteenth-century sea voyages, this paper aims to explore how these accounts drew on intertextual links with existing Buddhist records to fulfill the compilers' intentions. Specifically, this paper examines the structure and sources of biographical accounts detailing miraculous encounters between pilgrim monks and Buddhist deities during perilous situations at sea. By interpreting the role of these deities in the corpus of Buddhist literature and within Japanese Buddhist monasteries founded by pilgrim monks, this paper argues that the increasing emphasis on pilgrim monks' attainment of divine protection in their biographical records suggests a growing concern for reinforcing the authority of their dharma lineages. Moreover, the composition and reception of these miraculous accounts reflected the changing religious needs and reshaped strategies for promoting specific Buddhist sects in subsequent periods.

Japan's war reparations began to be paid to Burma and the Philippines in 1956 and ended in 1976. Approximately 65 years have passed since the reparation payment began. The nature of Japan's Official Development Assistance, which has been based on economic infrastructure and prioritises Asia, began with war reparations. Although post-war reparations are relevant to Japan's economic statecraft, previous studies have analysed only the negotiation process for individual countries. No comprehensive historical analysis of war reparations has been conducted so far. This paper fills this gap by analysing the declassified materials of the Ministry of Foreign Affairs and the state-of-the-art Japanese literature based on those materials. It also clarifies the characteristics of war reparations as part of Japan's Official Development Assistance by looking at the projects and goods paid by the reparations in each country. Furthermore, this paper challenges the conventional understanding of previous research on Japan's economic re-entry into Southeast Asia through reparations. The study concludes that reparations were unimportant in increasing Japan's exports to Asian countries. [ABSTRACT FROM AUTHOR]

In parallel with many other countries, the government of Japan has started to tackle coastal adaptations to climate change. In 2020, the national Basic Policy for Coastal Protection was revised to add the statement that coastal management should account for future changes in coastal hydrodynamic conditions due to climate change. Following this policy, the management body of each coast is requested to revise the Basic Plan for Coastal Protection by 2025. This paper first reviews the current legal frameworks and measures of coastal protection and conservation, such as disaster prevention and mitigation against stormy waves, storm surges and tsunamis, beach conservation, and maintenance of coastal protection facilities. Second, the paper outlines the recent actions taken for coastal adaptation to climate change. With example cases in Osaka and Tokyo bays, it is described how design conditions such as design waves and water levels should account for the influence of climate change. It is also described how adaptive beach management should be implemented accounting for projections of future beach changes. Finally, the paper discusses future challenges in coastal adaptation strategies to climate change in Japan, such as introduction of integrated coastal zone management and other potential options that have not been implemented in Japan.

This paper argues that the act of listening offered by active listening volunteers is a "gift" that requires reciprocity from elderly people. Active listening volunteers (keicho borantia) in Japan offer conversation and listening services for elderly people in local areas. Previous researchers investigate unsatisfying visits such as having boring conversations, and suggest the need for honing listening skills, or better pairing, and so on. This study, however, reveals that these solutions might not improve the situation, and, using participant observation and interviews, finds fundamental issues around reciprocity instead. First, and most importantly, volunteers do not realize that their listening functions as a "gift," which brings power dynamics, forcing elders either to stay as helpees, or to reciprocate. This paper, therefore, argues that even an act of listening in the field of volunteering can be perceived as a "non-free gift" by elderly people. Second, overemphasizing the importance of active listening obstructs reciprocity, letting volunteers cling to the role of listeners and helpers. In conclusion, this study suggests that volunteers need to understand three aspects: the importance of reciprocity; the fundamental power imbalance in caring activities; and the variety of reasons for elderly people to meet volunteers.

This paper examines an inertial response control for wind turbines in order to provide the system inertia decreased by the integration of asynchronous variable renewable energy sources. Specifically, an application of the temporal power surge, a strategy by which the output of a wind turbine can be temporarily increased with releasing the kinetic energy stored in the rotating mass, was proposed to address significant frequency drops in a microgrid. Since the rotational speed of turbine has to be decreased by this approach, it is necessary to further reduce the wind power output to recover the rotational speed after the temporal power surge. This drawback may lead to a second frequency drop, and it is effective to intentionally increase the rotational speed beforehand to mitigate this negative effect. However, this measure causes output curtailment under normal operating conditions. Hence, a determination method of the rotational speed considering the output curtailment was proposed in this paper to facilitate frequency regulation through the temporal power surge. The proposed methods for adjusting rotational speed are evaluated and their effectiveness were verified through numerical simulations. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

This paper presents a designed experimental simulation scheme for dynamic air gap eccentricity (DAGE) faults in permanent magnet synchronous generator (PMSG), along with the testing of their electromechanical characteristics. Unlike previous studies, this paper proposes and applies an experimental device setting scheme that enables accurate and convenient calibration of the DAGE fault degree, offering a novel solution for practical DAGE simulation. The experimental unit measures the electromechanical characteristics of the PMSG before and after the DAGE fault, taking into account the influence of load. The mechanical parameter considered is the stator vibration, while the electrical parameter is the circulating current parallel branches (CCPB) inside the stator winding. The characteristic frequencies of stator vibration and CCPB under the DAGE fault are analyzed based on the experimental results and verified through theoretical calculations and finite element analysis (FEA). The findings demonstrate the effectiveness of the proposed DAGE experimental device. Moreover, DAGE failure increases the strength of stator vibration and introduces new frequency components, namely fr and 2f ± fr. Under normal operation, the PMSG exhibits no CCPB. However, DAGE faults cause CCPB with frequency components of f ± fr. Moreover, the severity of the fault degree positively correlates with larger root‐mean‐square (RMS) values and characteristic frequency amplitudes of stator vibration and CCPB. Furthermore, the amplitude of stator vibration and CCPB decreases with increasing load. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC. [ABSTRACT FROM AUTHOR]

The increasing penetration rate of distributed energy brings more complex problems of voltage quality, safety and stability to the distribution network. A single optimal configuration of reactive power or energy storage is difficult to meet the increasingly diversified needs of modern power grids. This paper proposes a configuration strategy combining energy storage and reactive power to meet the needs of new energy distribution networks in terms of active power regulation and reactive power compensation, and to achieve tradeoff optimization in flexibility, voltage quality and economy, so as to adapt to the influence of new energy with different permeability. Firstly, the safety and stability evaluation system of distribution network is established with the target of flexibility demand and reactive power demand. Secondly, considering the coupling of planning layer and operation layer, a two‐layer model of energy‐reactive power optimization is established. After that, the gray wolf algorithm is used to solve the model, which enhances the global space exploration ability and reduces the possibility of falling into the local optimal. Finally, the improved IEEE33 node power distribution system is used for simulation test to verify the rationality and effectiveness of this scheme. The simulation results show that the scheme proposed in this paper can effectively improve the economy, security and stability of the distribution network, and can obtain an optimal configuration scheme with multi‐objective considerations under different new energy penetration rates. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

Does a warming world, where extremely hot summers are becoming more common, mean that cold summers will never again occur? It is crucial to know whether extremely cold summers are still possible, as such knowledge will significantly impact decisions regarding the further adaptation of crops to cold summers. Japan, which has suffered from many extremely cold summers, has managed past agricultural disruptions with emergency rice imports. In this paper, we show that a climate regime shift associated with the positive phase shift of the summer Arctic Oscillation occurred in 2010 in northeast Eurasia, making the occurrence of extremely cold summers highly unlikely as long as this new regime persists. In fact, Japan has not experienced a cold summer since 2010, while extremely hot summers have been frequent. Since 2010, a double-jet structure with subtropical and polar jets has strengthened, and the polar jet has meandered farther north of Japan, resulting in an upper-tropospheric anticyclone. This anticyclone, which extends downward and tilts southward, reaches southern Japan and prevents cold advection of oceanic air over the cold Oyashio. The Okhotsk high, known as the leading cause of cold summers, has occurred frequently in recent years; however, cold summers have not occurred due to the tilting anticyclone. The recent warming of the Oyashio weakens cold advection. The Pacific–Japan pattern, known as a remote tropical influence, has been weakened. A better understanding of the regime shift will help us understand the tilting anticyclone and the associated extreme summers in northeast Eurasia. Significance Statement: Extremely cold summers are among the most destructive natural disasters, both socioeconomically and agriculturally. Historically, food shortages due to cold summers have triggered wars. This paper proposes that a hemispheric-scale climate regime shift occurred in or around 2010. This regime shift has included warmings in the North Pacific and East Eurasian land surface temperatures. The regime shift is accompanied by the positive shift of the Arctic Oscillation (AO), a jet meander, and an upper-tropospheric anticyclone, making eastern Eurasia extremely hot. Our results imply that extremely cold summers are unlikely to occur in eastern Eurasia so long as this regime persists. Moving forward, it is important that the link between this regime shift and global warming be explored. [ABSTRACT FROM AUTHOR]

Objective: To determine impact of undertaking an international educational program during a nurse's or midwife's pre-registration program on subsequent practice, focusing on how nurses and midwives were transformed personally through participation in such programs. Background: Participation in international educational programs has been reported to enhance nursing and midwifery students' personal and professional development, however long-term impacts remain unclear. This paper presents findings drawn from a larger grounded theory study. Study design and Methods: Charmaz's grounded theory methodology was used to elicit experiences from 13 general nurses, two mental health nurses, three midwives and four dual qualified nurse/midwives across eight different countries. Data analysis led to the creation of three categories, with this paper reporting on the category of Developing as a Person. Findings: Participation in international educational programs can be transformative for nurses and midwives with long-lasting impacts, contributing positively to their personal growth and development. Discussion: The study findings underscore significant long-term impacts of international educational programs for nurses and midwives. These outcomes highlight the importance of incorporating international experiences into healthcare education. Conclusion: By providing opportunities for healthcare professionals to engage with diverse settings and populations, organisations and educational institutions can foster the development of well-rounded and globally competent practitioners. Implications for research, policy, and practice: The study's findings hold significant implications for research, policy, and practice in healthcare education. To deepen our understandings, additional longitudinal research across diverse countries is warranted. Policymakers have an opportunity to acknowledge the positive impact of these programs on the personal growth and development of nurses and midwives, potentially leading to the integration of global competency requirements into licensure programs. In order to provide comprehensive education, educational institutions should consider the inclusion of study abroad opportunities, cultural exchanges, and global clinical placements within nursing and midwifery curricula. What is already known about the topic? • International educational programs are widely used as a way of developing nursing and midwifery students' cultural understandings. • Previous studies have reported on short-term impacts of international educational programs. What this paper adds: • Long-term impacts of participation in an international educational program on nurses and midwives are described. • Personal development and subsequent transformations occur for nurses and midwives as a result of participation in international educational programs.

This paper presents an exploratory examination of regional think tanks in Japan and outlines the contribution that such an examination can make both as a comparative Asian case for regional think tank research as well as in theorization of regional think tanks on the basis of various constructs of place priority. After briefly outlining the main trends and tensions in the study of think tanks in general and providing an overview of the literature on think tanks in Japan, the paper focuses specifically on the small-scale regional think tanks situated throughout Japan. The conclusions are twofold. First of all, the research builds on previous research in furthering the descriptive characteristics of Japanese regional think tanks. Second, the research outlines various place priority constructs through which regional think tanks can be described, compared, and analyzed. These are the specific dimensions of influence that place priority think tanks bring to their locale: local development through infrastructural advocacy, local development through objective information generation, and local development through knowledge and leadership cultivation. The analysis that leads to these conclusions speaks on a broader level to the contribution that such a focus on small-scale think tanks can make to research on think tanks at large. Case study of such regional think tanks offers insight into a major tension confronting contemporary think tank research: agenda advocacy versus the various other objectives that think tanks aim for.

As a memory place that exemplifies contemporary Zainichi experiences, the Utoro district in Kyoto, Japan, entails stories of Japan's colonial exploitation and postcolonial oppression, yet simultaneously reveals human hope, cooperation, and solidarity. First formed for the Korean workers and their families mobilized for the construction of a military airport during World War II, Utoro was left abandoned for decades in postwar Japan. Its Korean residents have suffered from continuous eviction suits, harassment, and violence including the most recent arson attack in 2022. At the same time, these intricacies of colonial origin and postcolonial controversy also invited networked grassroots efforts among the Japanese and Koreans to remember and reconstruct the place's sociohistorical meanings, resulting in the construction of the Utoro Peace Memorial Museum in 2022. This paper highlights the significance of Zainichi experiences with/in Utoro through an analysis of identity, discourse, and representation of the place. Drawing upon collective memory scholarship and adopting a theoretical framework of re-collection, the paper unravels complex meanings of a site in relation to human acts of remembering, making sense of, and finding significance to our past experiences with/in it. By situating visual and discursive voices of the Utoro community (Zainichi in Utoro), such as its former residents' oral testimonies and museum displays, this study elucidates the significance of Utoro in Zainichi history. This paper argues that Utoro projects contradictory positionalities of Korean subjects as both integral and excess in the history of colonial and postcolonial socio-politics of ethno-racial Other in Japan.

Sports mega-events, like the Rugby World Cup, are often considered as a major platform for the celebration and reinforcement of nationalism. However, there is an emerging strand of research which contends that the host nations are increasingly presenting themselves with diverse, inclusive and cosmopolitan characteristics and, in turn, forms of nationalism have undergone some noticeable changes in more recent times. In this paper, we pursue an argument that Japan as the host of the 2019 Rugby World Cup projected the nation with a cosmopolitan outlook ultimately to sustain or even strengthen national interest and identity through the process of 'cosmopolitan nationalism'. Methodologically, the research deployed critical discourse analysis to examine media representations of Japan as the host nation in general, and its national team in particular, within one of the leading Japanese newspapers as well as a range of other publicly available resources and materials in relation to the Rugby World Cup. In result, the study reveals the ways in which the discourse of 'One Team', embracement of foreignness and incidents of international exchanges during the event were mobilised to generate 'thin' cosmopolitan moments and, at the same time, were incorporated into the narratives of Japan's success on the world stage through conditional acceptance of foreignness and diversity. Consequently, this paper offers both a theoretical underpinning for and empirical evidence of the emerging linkage between sports mega-events and cosmopolitan nationalism. [ABSTRACT FROM AUTHOR]

In this letter, a disposable micropower source was developed by integrating a microbial fuel cell (MFC) in filter paper. The paper‐based MFC could harvest electrical energy generated by Escherichia coli during the metabolic process. The air‐dried biofilm anode was activated by water for on‐demand electricity generation. This study aimed to optimize the anodic and cathodic materials for maximization of the MFC performance. The concentration of activated carbon powder in the anode and potassium ferricyanide in the cathode were optimized. The paper‐based MFC with the optimum anode and cathode generated a maximum power density of 8.4 µW/cm2. © 2019 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.

Background: Atypical antipsychotic medications have often been used in the treatment of behavioral and psychological symptoms of dementia (BPSD). Recently, the US Food and Drug Administration (FDA) issued new safety information concerning atypical antipsychotic drugs, indicating that their use may increase the risk of cardiovascular adverse events among elderly adults with BPSD. Based on this information, the Japanese Ministry of Health, Labor and Welfare issued a similar warning against the use of atypical antipsychotic drugs licensed in Japan. We then sought to determine whether or not the use of typical antipsychotics should be recommended to replace atypical antipsychotics. In this paper, we discuss the influence of these warnings on the withholding of use of risperidone exemplified in seven case histories. Methods: Seven inpatients who exhibited BPSD received risperidone monotherapy in our hospital. In response to the FDA notice, the atypical antipsychotics used to treat these patients were replaced with typical antipsychotic agents. Results: During the period of risperidone administration, all patients exhibited clinical improvement compared with their baseline results and showed no adverse events. Two of our seven patients developed psychotic exacerbation and exhibited extrapyramidal symptoms coinciding with the replacement of risperidone with conventional antipsychotics. Conclusion: To the best of our knowledge, this is the first clinical report on the influence of the FDA alert on the use of atypical antipsychotics for psychotic symptoms in older patients with dementia in Japan. In two of our seven BPSD cases, there was no benefit from taking conventional antipsychotics. Our results lead to the conclusion that the use of typical antipsychotics should not be recommended to replace atypical antipsychotics. Although close attention should be paid to the FDA alert, clinicians must take into consideration the balance of benefits and risks when evaluating the appropriate use of antipsychotics in older patients with dementia.

Enzootic bovine leucosis (EBL) is a neoplastic disease of cattle caused by Bovine leukaemia virus (BLV). EBL causes great economic losses, so a fast and reliable diagnostic method is critical for understanding the status of BLV. This will allow us to control BLV infections efficiently and mitigate economic losses. In this study, we established a direct diagnostic test for BLV using dried blood‐spotted filter papers without sample pre‐treatment. The study was based on 159 clinical blood specimens collected in EDTA from one farm in Kyushu, Japan. The blood‐spotted filter papers were used as the template for direct filter PCR. When an ELISA was used as the diagnostic gold standard, the sensitivity and specificity of the direct filter PCR were 90.1% and 97.5%, respectively. The kappa value for the direct filter PCR and real‐time PCR methods was 0.97. The dried blood samples spotted onto filter papers were stable for at least 10 days at room temperature, even when the samples were from cattle with a low BLV proviral load. Direct filter PCR is a rapid, easy, reliable and cost‐effective diagnostic test that directly detects the BLV proviral genome in clinical blood specimens without DNA extraction. Moreover, it simplifies the collection, transportation and storage procedures for clinical blood specimens. [ABSTRACT FROM AUTHOR]

We postulated that disinfection of viable Trichophyton species in shoes would help reduce the number of patients with tinea pedis in Japan and that this might be accomplished safely using volatile components of essential oils. As vapor of lemongrass (Cymbopogon citratus) oil and citral have strong antimicrobial activities against Trichophyton, we examined the conditions under which lemongrass oil or citral show optimal antimicrobial activity in shoes. First, we investigated whether or not a strong antimicrobial effect could be obtained by combining with terpene aldehydes or aromatic aldehydes. When combined with citral, perillaldehyde showed superior antimicrobial activity to citronellal, cinnamaldehyde, cuminaldehyde, hydroxycitronellal, and vanillin. The combined effects of citral and perillaldehyde against Trichophyton mentagrophytes, Bacillus subtilis, and Candida albicans as volatile components dotted on filter paper placed away from the petri dish inoculated with fungi or bacteria were examined. Citral (2.5 mg/mL) and perillaldehyde (2.5 mg/mL) showed a greater inhibitory effect on growth of C. albicans than either solution alone in the aromatogram (disc diffusion) descent method (fractional inhibitory concentration [FIC] index of 0.58). Citral (2.5 mg/mL) and perillaldehyde (1.25 mg/mL) vapors in a closed box synergistically inhibited growth of B. subtilis and T. mentagrophytes (FIC indexes of 0.5 and 0.38, respectively). These results suggested that this combination would be safe and useful for disinfection of shoes. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of mass screening of newborns for congenital hypothyroidism of central origin (CH-C) by measurement of free thyroxine (FT4) and thyroid-stimulating hormone (TSH). Design: Questionnaire-based survey of CH-C patients born between 1999 and 2008 in Kanagawa prefecture, Japan. Methods: TSH and FT4 levels in dried blood spots on filter paper were measured using ELISA kits, and CH-C was diagnosed at FT4 levels below a cutoff of 0.7 ng/dl (9.0 pmol/l). Survey results were collated with the database created by the screening organizer Results: Twenty-four CH-C patients (18 males) were identified, 14 of whom had multiple pituitary hormone deficiencies (group M), eight had isolated CH-C (group I), and two had undetermined pituitary involvement (group U). In groups M, I, and U, the number of patients with FT4 levels below the cutoff value at screening was five (36%), seven (88%), and one (50%) respectively; other patients had been diagnosed clinically. Thus, 13 patients were true positives, while nine were false negatives, yielding screening sensitivity of 59.1% and positive predictive value of 11.5%. The calculated sensitivity was 81.8% at a higher cutoff value of 0.9 ng/dl (11.6 pmol/l). The overall incidence of CH-C was estimated at 1 in 30 833 live births, while that of CH of thyroidal origin (CH-T) is 1 in 3472 live births in Kanagawa prefecture (CH-T/CH-C, 8.9). Conclusions: Newborn screening with combined FT4 and TSH measurements can identify a significant number of CH-C patients before manifestation of clinical symptoms, but a more appropriate FT4 cutoff value should be considered.

Objectives: To provide a participant's account of the development of a paper commissioned by the tobacco industry examining the reliability of self reported smoking status; to redress the distorted report of this Japanese spousal smoking study which evaluated the reliability and validity of self reported smoking status, and estimated confounding by diet and lifestyle factors. Design: Repeated interviews on smoking status and its verification by environmental and biological markers for environmental tobacco smoke (ETS) exposure. Setting: Urban wives in Osaka City and Sizuoka City, Japan. Participants: Semi-random sampling of 200 wives in each city. From the Osaka subjects, 100 non-smoking wives were selected for the validity study. Main outcome measures: Kappa coefficient for reliability of self reported smoking status. Correlation coefficients between environmental nicotine concentration, cotinine in saliva and urine, and self reported smoking status. Results: The K coefficient for the repeated interview was high suggesting sufficient reliability of the response. The proportion of self reported current smokers misclassified as non-smokers was equivalent to the misclassified self reported non-smokers. Ambient concentration of nicotine and personal exposure to nicotine correlated with each other and also with salivary cotinine and self reported ETS exposure but not with urinary cotinine/creatinine ratio (CCR). There was no major difference in diet and lifestyle related to husband's smoking status. Conclusion: Self reported smoking status by Japanese wives shows high reliability. It also shows high validity when verified by both nicotine exposure and salivary cotinine, but not by CCR. A previous report questioning the credibility of self reported smoking status, based on questionable CCR, could thus be of dubious validity. In addition, possible dietary and lifestyle confounding factors associated with smoking husbands were not demonstrable, a finding not reported previously. Using all the data from this project changes the conclusion of the previous published report. In addition to the distortion of scientific findings by a tobacco industry affiliated researcher, anti-smoking campaigners made attempts to intimidate and suppress scientific activities. These distortions of science should be counteracted. [ABSTRACT FROM AUTHOR]

This paper presents an account of a Sakhalin Ainu (also Enciw'itah, isolate, Russia and Japan) construction that semantically encodes an agent-patient interaction and that is characterized morphosyntactically by the expression of the agent with an oblique. In the analysis to follow, this construction is named 'impersonal passive' by analogy with a structurally and functionally similar construction attested in the Southern Hokkaidō dialects of Ainu. Keeping the main focus on eastern dialects, the paper takes a primarily semantic approach to the East Sakhalin Ainu impersonal passive and underlines a number of striking structural differences with the Hokkaidō counterpart. In addition, it will be argued that in the north-eastern dialects of Sakhalin Ainu, the impersonal passive can be described as an object-individuation construction (oic), which marks a patient object as referential and definite and has the pragmatic extension of overtly flagging the topicality of this object at the discourse level. As such, the oic compensates for the lack or non-obligatoriness of overt marking for definiteness and topicality in Sakhalin Ainu. The present paper adds to our knowledge on the still under-described Sakhalin variety of Ainu and to our understanding of the verbal and nominal semantics of Ainu more generally, which to date remains a largely unexplored topic.

While most Japanese legal dramas feature a male protagonist as the hero, a significant amount of screen time is allocated to the courtroom heroine as well. This is in spite of statistics that show that women are still underrepresented in the Japanese legal profession. Surveying post-2000 Japanese legal television dramas reveals that televisual female legal professionals conform to two stock character types and corresponding narrative arcs: the rookie lawyer, and the elite but "fallen" lawyer. While most shows only feature one such heroine, Onna wa sore wo yurusanai (2014) features two, representing both types. This paper closely examines how the two stock characters are portrayed in this drama and the relevance of each to the larger narrative which reveals the difficulties female legal professionals face while navigating Japan's male-dominated legal domain. The paper concludes that the increasing presence of the heroine in legal dramas and her overall positive portrayal, reflects the Japanese government's goal of raising the number of legal professionals and women's participation in all public sectors by 2020, and also indicates changing attitudes on the part of Japanese society toward the need to give greater recognition and social acceptance to female legal professionals.

To optimize patient prognosis, patient needs, including unmet needs, should be adequately assessed. However, such needs are more challenging to report and, consequently, more likely to go unmet compared with the needs reported by physicians. We aimed to determine the appropriate direction of future research on unmet medical needs in rheumatic diseases in Japan by conducting a literature review. We searched PubMed and Web of Science using 23 terms linked to unmet medical needs for major rheumatic diseases in Japan. Further, we collected articles on health-related quality of life and investigated the scales used for assessment, as well as whether the terms "unmet needs" or "unmet medical needs" were used. We identified 949 papers on 10 diseases, including systemic lupus erythematosus, systemic sclerosis, dermatomyositis, juvenile idiopathic arthritis, adult-onset Still's disease, antiphospholipid syndrome, mixed connective tissue disease, Takayasu arteritis, Sjögren's syndrome, and Behçet's disease; 25 of the 949 papers were selected for full-text review. Fifteen articles on five diseases were related to health-related quality of life. The term "unmet needs" was used in only one article. Six out of 15 studies used the 36-item short form survey, whereas the scales used in other studies differed. The optimal treatment plan determined by a physician may not necessarily align with the best interests of the patient. In clinical research, cross sectional and standardized indicators of health-related quality of life should be employed along with highly discretionary questionnaires to assess and optimize resource allocation in healthcare and simultaneously achieve patient-desired outcomes.

This paper provides a systematic account of simultaneous recruitment of new graduates (SRoNG), the predominant hiring practice of big companies in Japan. The authors characterise SRoNG as macro-level coordination in the process of new graduate recruitment between companies and universities, along with homogeneous hiring conditions offered by individual firms, consisting of same initial salaries, initial internal vocational training, and absence of job specification. The paper further provides a historical account of SRoNG's emergence, tracing it back to early-modern government structures, education expansion, wage control efforts, and the system's expansion and establishment as a predominant institution. Finally the paper focuses on SRoNG's more recent empirical evolution. The main business association, Keidanren, proposed to abandon the practice in the wake of intensified competition with foreign multinationals in the recruitment of new graduates. While there are noteworthy ongoing changes, the authors suggest that SRoNG is unlikely to suffer more than a partial and minor abandonment. [ABSTRACT FROM AUTHOR]

Path planning is one of the fundamental issues in the research field of robot. In the last decades, Rapidly‐exploring Random Tree star (RRT*) was one of the chosen path planner for robot with its probabilistically complete. In this paper, an improved bidirectional RRT* path planner for robot is proposed (Bi‐RRT*), which has planned path with safety and smoothly guarantee. The main contributions of this paper include, firstly, combining the backtracking idea of the Quick‐RRT algorithm with the greedy search strategy of the RRT‐Connect algorithm, which can reduce the path cost and improve the operation efficiency of the algorithm. Second, in order to further reduce the running time of the algorithm, a new collision detection algorithm based on cross‐product is proposed to replace the conventional collision detection strategy. To ensure the quality of the path, two post‐processing strategies, path optimization strategy and path smoothing strategy, are proposed. Path optimization strategy is based on triangle inequality, and two optimization methods are proposed to effectively reduce the path cost. The path smoothing strategy based on the Bezier curve improves the continuity of a smooth arc and is better applied to path smoothing. Simulation results for both virtual and real environments show the advantages of combining Quick‐RRT and RRT‐Connect and verify the effectiveness of the proposed collision detection algorithm. Compared with similar algorithms, the proposed Bi‐RRT algorithm has higher operational efficiency, smaller path cost, smoother planned paths, and improved path quality. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

Aim: The aim of this study was to determine the risk factors for household transmission of the omicron variant of SARS‐CoV‐2. Background: The household infection rate has been reported to be higher for the omicron variant than for non‐omicron variants of SARS‐CoV‐2. Determination of the risk factors for household transmission of the omicron variant is therefore important. Design: A Retrospective Cohort Study was conducted. Methods: When family members of health care workers (HCWs) were found to be infected with SARS‐CoV‐2, the HCWs had to receive two nucleic acid amplification tests for SARS‐CoV‐2: immediately after and 5 to 10 days after the onset of COVID‐19 in the family members. Risk factors of household transmission were analysed by comparing cases (HCWs infected with SARS‐CoV‐2) and controls (HCWs not infected with SARS‐CoV‐2) using multivariable analysis. Results: Unvaccinated status (OR: 3.97), age of index cases (≤6 years) (OR: 1.94) and staying at home with index cases (OR: 10.18) were risk factors for household transmission. Conclusion: If there is a strong desire to avoid household infection, family members infected with SARS‐CoV‐2 should live separately during the period of viral shedding. Summary statement: What is already known about this topic? During the COVID‐19 pandemic, nurses have been exposed to SARS‐CoV‐2 not only from COVID‐19 patients but also from family members infected with SARS‐CoV‐2 but prevention of SARS‐CoV‐2 infection to nurses is important to maintain health services function.The household infection rate was reported to be higher for the omicron variant (42.7%) than for non‐omicron variants (36.4% for Alpha, 29.7% for Delta and 22.5% for Beta). Determination of the risk factors for household transmission of the omicron variant is therefore important. What this paper adds? Unvaccinated HCWs had higher transmission rates (OR: 3.97, 95% CI: 1.22–12.88) than those of HCWs who received more than two doses of BNT162b2 or mRNA‐1273 mRNA COVID‐19 vaccines.Index cases aged 6 years or younger had higher transmission rates (OR: 1.94, 95% CI: 1.13–3.35) than those of index cases aged 7 years or older.The odds of transmitting to HCWs was higher (OR: 10.18, 95% CI: 2.98–34.72) for HCWs who stayed at home with the index cases than for HCWs who spent time in a different building from the index cases. The implications of this paper: If there is a strong desire to avoid household infection, family members infected with SARS‐CoV‐2 should live separately during the period of viral shedding.

Aims: This work aims to map instruments available in Japanese that have been assessed for reliability or validity for measuring evidence‐based practice (EBP) among clinical nurses. Background: As EBP competencies comprise various domains, many EBP instruments have been developed. However, instruments available in Japanese for measuring EBP have not been reported systematically. Design: We conducted a scoping review. Data sources Two different bibliography databases were searched to identify EBP instruments published until 2019: ICHUSHI (for Japanese articles) and PubMed. Review methods: After relevant studies were screened and identified, study profile characteristics were extracted to identify EBP instruments in Japanese, and the quality of methodology for developing such instruments was evaluated. This information was recorded and the characteristics were descriptively summarized. Results: Ninety potentially relevant articles were identified, of which seven articles and nine instruments were included in this review. All instruments were based on self‐reported self‐efficacy and attitudes. Few Japanese instruments included all the steps required for EBP. The overall reporting quality of each instrument was low. Conclusions: EBP instruments available in Japanese are extremely scarce. The study results show that it is difficult to measure the various aspects of EBP with the existing instruments. Summary statement: What is already known about this topic? A systematic review reported that more than 100 instruments for evaluating evidence‐based practice (EBP) have been developed worldwide.Even if no language restrictions are applied in systematic reviews, international databases often do not cover publications in languages other than English, or those that are from Asia, Africa, or South America.Japanese EBP instruments have not been cited in systematic reviews of EBP. What this paper adds? EBP instruments available in Japanese published until 2019 were extremely scarce.There was little variation in the outcome domains and scale components of EBP instruments available in Japanese.An EBP instrument originally developed in Japan included a subscale on nursing research that considers the cultural characteristics specific to Japan. The implications of this paper: This review could help researchers, educators, and practitioners in choosing EBP instruments available in Japanese to measure nurses' readiness or competencies for EBP.A literature review of non‐English language publications could address the language limitations of previous systematic reviews in mapping EBP instruments.

This paper analyses international student prospectuses from twenty‐two Japanese universities involved in the Top Global University Program (TGUP) to examine how universities in Japan present and understand internationalization. International prospectuses were analysed using qualitative text analysis to generate a series of themes connected to university internationalization. Different categories of TGUP participant universities were compared to better understand the differences between how different participant types present and understand internationalization. The findings suggest that while there are differences between participant types and individual universities, overall, there appears to be a tension between understanding internationalization as an authoritative, university‐centred activity and as a student‐centric activity in which students are active participants. Furthermore, it found that although rankings are an important aspect of the TGUP, few prospectuses mentioned rankings. The paper suggests possible reasons for this omission based on the TGUP participant type. Finally, this study offers insights into how Japanese universities understand internationalization and position themselves as international institutions. [ABSTRACT FROM AUTHOR]

With the emergence of digital technologies, we have witnessed a rapid growth of the sharing economy in recent years. In fashion industry, sharing economy concept is also widely applied. Instances can be found all over the world, like Rent the Runway, Golden Tote, Stitch Fix, and Le Tote in the US, Air Closet in Japan, Y Closet, Ms Paris, and Dora's Dream in China, etc. In this paper, motivated by the industrial practices of fashion sharing platforms, we first conduct a literature review on business operations of sharing platforms, including the sharing platform operations, digital and information technologies employed in sharing economy, business models, and sustainability and circularity in business operations. Afterwards, we analyze the challenges faced by fashion sharing platforms by exploring the two leading fashion sharing platforms in the US and in China, respectively. At last, we propose future research directions on fashion sharing platform operations and conclude the paper. [ABSTRACT FROM AUTHOR]

In the context of the COVID-19, it is very significant to explore the dynamic fluctuation of China's export growth to the international market and examine the causes of this fluctuation in a multi-dimensional way. The dynamic fluctuation level is measured in the short and medium-long cycle respectively based on monthly data. Factor decomposition of the dynamic fluctuation is made from the growth effect, the structure effect and the competitiveness effect by the improved CMS model, which results show that the growth effect has decreased first and then increased; The structure effects include market structure effects and commodity structure effects, and the former effect basically fluctuates around the X-axis while there is a negative commodity structure effect; There are different specific competitiveness effects on 21 categories of goods. China should rely on the RCEP agreement to strengthen and stabilize trade cooperation other countries, and strengthen its core position in the industry chain and value chain in the Asia Pacific region. The current paper creatively introduce the trade expansion margin including the ternary margin and product structure into the CMS model, explaining the internal relationship between the trade expansion margin analysis at the product- market level and the CMS analysis at the overall level; meanwhile, this paper analyses the dynamic fluctuation structure of China's export growth to Japan and South Korea through a CMS factor decomposition from the perspective of technological structure and factor ladder, and studies the source and dynamic distribution evolution of this growth pattern.

Zen practice is often associated with aloof silence and introspection. However, any visitor to a Japanese Zen training temple will be surprised by the abundance and richness of the acoustic environment. In effect, every moment of the training schedule is accompanied, chronicled, and choreographed by percussions and chanting vocals. This paper will introduce this sonic environment and explain how different sounds construct the training experience. In particular, I will focus on sound instruments that coordinate daily activities, such as bells, gongs, drums, and the like, arguing that they are essential to Zen practice. The first part of the paper explains the unique characteristics of a Japanese Zen training temple, focusing on ritual sound instruments and their place within the monastic soundspace. The second part examines the meaning of these instruments as described in Zen canonical writing, focusing mainly on Baizang's monastic regulation and different references to it by Japanese masters throughout history. The third part explores how contemporary monastics understand sound instruments and their function in regulating the body, conveying values, and evoking spiritual transformation.

Since the Japanese government put forward the concept of Society 5.0 in January 2016, smart society has aroused extensive discussion in the international academic circle. However, this concept has been hardly discussed or cited in China. What is the root cause of this observation? Based on this question, this paper systematically reviews the existing literature on smart society both domestically and internationally. It provides a reverse critique of the misguided viewpoints supporting Society 5.0 from the perspectives of concept, motivation, elements, and goals. It also conducts a comprehensive analysis of the existing critical arguments against Society 5.0 in academia, considering theories, motivations, elements, and consequences, providing a forward critique. The paper further analyzes failed cases of smart society implementation, offering practical critique. By considering three perspectives, it identifies and categorizes the critical arguments against Society 5.0, forming three arrays of critique. Additionally, the paper addresses the fundamental reasons for the criticism of Society 5.0 in China and proposes an alternative vision: Civilization 5.0 as the ideal society of the future. Civilization 5.0 encompasses three transformative changes: eco-lization, intellectualization, and inclusiveness. In this new civilization, society needs to embrace ecological transformation, intellectualization, and multi-decision-making. [ABSTRACT FROM AUTHOR]

This paper begins by providing a history of Japanese law pertaining to special education and its change towards a more inclusive education with the ratification of United Nations Conventions of the Rights of People with Disabilities. With the changes in laws, more children with constant medical care needs in Japan have the opportunity to attend mainstream schools. The recent court case, Kosuge v. Kanagawa prefecture and Kawasaki city, ruled against a child with medical care needs to attend mainstream school and made the judgment that a special needs school (tokubetsushien gakkō) is the appropriate placement for the child based on the child's disability type and degree of disability rather than needs and regardless of the wishes of the child's parents. This paper explores the case judgement and discusses where Japanese special education laws fall short similar to that of the US system based on Individuals with Disabilities Education Act. We suggest the need to keep inclusion as the basic human rights aligned with the Article 24 of the UNCRPD rather than focusing on the continuum of education principle in IDEA, and operationalise the law into practice to make integration of children with disabilities, including children with constant medical care needs, into mainstream education schools.

Energy internet zones (EIZ) supply multiple energy carriers to customers in certain regions. They can achieve high energy efficiency by energy cascade utilization. In mid‐term, they participate in the wholesale market and retail market simultaneously. Customers can shift their energy use among different hours and energy carriers to satisfy demand according to the retail prices. Unfortunately, multiple energy systems and markets bring various uncertainties on demand and prices. In this paper, the weekly bidding strategy for the EIZ is proposed to determine the optimal bilateral contracts to sign and the optimal energy retail prices. In retail market, the satisfaction degree and elasticity matrix describe customers' response. Distributionally robust optimization is adopted to consider the distributional uncertainties of random variables and Worst‐case Conditional Value‐at‐Risk is employed for risk management. The distributional uncertainties of pool prices and elasticity matrix are discussed in this paper. An EIZ in Shanghai, China is adopted to illustrate the proposed strategy. The results have great resistance to distributional uncertainties. The risk aversion and satisfaction degree affect the EIZ's strategy in wholesale market and retail market, respectively. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

This paper aims to show a possible path to address the introduction of intimate digital technologies through a phenomenological and postphenomenological perspective in relation to Japanese and Chinese contexts. Digital technologies are becoming intimate, and, in Japan and China, there are already many advanced digital technologies that provide digital companions for love relationships. Phenomenology has extensive research on how love relationships and intimacy shape the subjects. At the same time, postphenomenology provides a sound framework on how technologies shape the values and meanings we have. Thus, this paper introduces two digital technologies in Japan and China (Love Plus and XiaoIce chatbot), and it analyses according to the elements proposed by phenomenology and postphenomenology. In conclusion, this paper shows how digital companions like Love Plus and XiaoIce chatbot change who we are and the values and meanings we have according to the phenomenological and postphenomenological framework. These entities might not be human, but they shape who we are as human beings and the meanings and value we give to love. [ABSTRACT FROM AUTHOR]

At present, the National Metrology Institute of Japan provides six national primary pH buffers under the Japan Calibration Service System. Each batch of these buffers is certified by the primary pH method using a Harned cell. On the basis of these primary buffers, the designated laboratories supply the secondary and working pH standards using a high-precision pH meter. This paper provides an estimate of the batch-to-batch reproducibility of the primary pH standard production based on the history of the certification of primary carbonate buffers in NMIJ. This buffer, which was chosen as the subject of the study because of the relative difficulty of its measurements (and thus a greater dispersion of results), is nominally the 0.025 mol kg−1 equimolal solution of disodium carbonate and sodium hydrogen carbonate. As its pH value is significantly affected by the purity of the reagents used, the evaluation of their source materials is made by both pH measurements and acidimetric gravimetric back titrations. Considering the experimentally determined pH reproducibility of ca. 0.010, potential risks to the pH accuracy are discussed when using recipe-based carbonate pH standards. [ABSTRACT FROM AUTHOR]

Purpose. This study aims to elucidate the gender gaps in the strategies for maintaining the social participation and interaction of older adults with people in a local community. Methods. The subjects were 130 older adults aged 65 years or older and independently living in their homes in Saitama, Saitama Prefecture, Japan. The authors conducted an anonymous questionnaire survey on paper and performed multiple regression analysis for men and women separately using the Lubben Social Network Scale-6 (LSNS-6) as the dependent variable. Results. Among the independent variables used for the analysis, those that significantly influenced LSNS-6 in men were social activities related to the daily life satisfaction of the elderly (SARDS). The independent variables that significantly influenced LSNS-6 in women were SARDS, sense of coherence-13 (SOC-13), and the number of family members living with the subjects. Discussion. Health promotion is not associated with interaction with people in men compared with women. [ABSTRACT FROM AUTHOR]

In order to support the learning of novice students in Java programming, the web-based Java Programming Learning Assistant System (JPLAS) has been developed. JPLAS offers several types of exercise problems to foster code reading and writing skills at different levels. In JPLAS, the code writing problem (CWP) asks a student to write a source code that will pass the test code given in the assignment where the correctness is verified by running them on JUnit. In this paper, to reduce the teacher's workload during the marking process, we present the answer code validation program that verifies all the source codes from a large number of students for each assignment and reports the number of passing tests for each source code in the CSV file. Besides, to test a source code with various input data, we implement the test data generation algorithm that identifies the data type, generates new data, and replaces it for each test data in the test code. Furthermore, to verify the correctness of the implemented procedures in the source code, we introduce the intermediate state testing in the test code. For evaluations, we applied the proposal to source codes and test codes in a Java programming course in Okayama university, Japan, and confirmed the validity and effectiveness.

As the most significant interannual signal in the tropical Pacific, the influence of ENSO on the interannual variability in TC genesis location in the western North Pacific (WNP) has received much attention in previous studies. This paper mainly emphasizes the underlying SST factors independent of the ENSO signal and explores how they modulate interannual tropical cyclone genesis (TCG) latitude variability. Our study finds that the meridional sea temperature gradient (SSTG) between the Kuroshio Extension and the WNP still has a significant effect on the interannual variability in the TCG latitude after removing the effect of ENSO (r = 0.6). The interannual forecasts of the TCG latitude were effectively improved from 0.67 to 0.81 when the ENSO-independent SSTG and ENSO were regressed together in a multi-linear regression. We then propose an ENSO-independent physical mechanism affecting the TCG latitude. The equatorward (poleward) SSTG excited the positive (negative) Pacific–Japan telecorrelation pattern over the WNP, forming Rossby wave trains and propagating northward. A significant cyclonic vortex (anticyclonic vortex) with strong convective development (suppression) developed near 20° N, leading more TCs to the northern (southern) part of the WNP. These findings provide a new perspective for the prediction of the interannual variability in the TCG latitude. [ABSTRACT FROM AUTHOR]

This paper devised a novel Christmas‐tree structure for flexible neural probes, which features recording sites on side‐branches that can be folded along the shank of the probe by temporary encapsulation before implantation. This design reduces the size of the implant and minimizes the surgical footprint. Upon implantation, the temporary encapsulation dissolves in vivo, leading to self‐stretching of the branches, and an expansion of the lateral detecting range of the probe. We conducted in vitro experiment with our probe in 0.6% agar that mimics the brain tissue environment. The results demonstrate that the neural probe we have developed exhibits self‐stretching ability and provides an increased lateral recording range without causing additional damage to the brain tissue. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

Electricity, as a sustainable energy carrier, plays a central role in the transition scenarios for carbon neutralization of energy systems. Expanding the potential of electricity requires intelligent integration of electricity infrastructures and electricity markets with distributed energy resources (DERs) including roof‐top solar photovoltaics (PVs), controllable loads, and storage batteries. This integration will advance the management of power distribution grids, resulting in harmonization of the distribution grids and variable renewable generation. In the foreseeable future, the DERs will be actively used to perform advanced management of power distribution grids and compensate fluctuation in variable renewable power generation such as PVs and wind power. Market‐based coordination mechanisms are already practiced in large‐scale electricity production, electricity trading and transmission around the world. Using these mechanisms at the distribution grid level to integrate numerous flexible devices into the grids remains an important research topic. This paper reviews the role of DER integration toward carbon‐neutral power systems, the state‐of‐art and challenges associated with market‐based approaches for integrating flexible demand, distributed generation, and storage. Methods for assessing the value of DER aggregation such as virtual power plants and microgrids are also explored. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

Cu‐Sn transient‐liquid‐phase bonding has a limit in achieving small diameter/high‐density bumps due to the extrusion of the melted Sn layer during bonding. This paper report a new method that can fabricate small diameter Cu‐Sn bumps with 5 μm diameter and 25 μm pitch based on a new thermal reflow and pre‐bonding method that enables solid‐state Cu‐Sn reaction for avoiding Sn extrusion. Using the new method, 3D integration of a 640 × 480 MEMS array on a CMOS circuit chip has been demonstrated. This method can be used in 3D integration of MEMS arrays and CMOS circuits such as micromirror arrays. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

This paper presents layer‐by‐layer additive manufacturing (AM) of molten metal microdroplets and dielectric materials to fabricate multilayer hybrid circuit boards featuring interdigitated 3D capacitors. The printed metal lines have a low resistance of 5 mΩ/mm, 12 times lower than state‐of‐the‐art conductive inks. Exploiting the advantages of Sn‐based oxide as an ideal candidate for Electrical Energy Storage Systems (ESS), we successfully fabricated an out‐of‐plane capacitor module using a combination of polymer and metal materials. The fabrication process exhibited an exceptional aspect ratio of 16, illustrating the successful incorporation of 20 metal layers in the out‐of‐plane capacitor module. Q factor obtained for the 3D capacitor was in the range of 66–500. Additionally, a fully automated printing technique was employed to produce a multilayer hybrid electrical printed circuit board (PCB), eliminating the need for post‐processing. This streamlined approach presents an efficient and comprehensive solution for the one‐stop printing of intricate electrical circuits. © 2024 The Authors.
