This paper studies the problem of federated training of a deep neural network (DNN) over a random access channel (RACH) such as in computer networks, wireless networks, and cellular systems. More precisely, a set of remote users participate in training a centralized DNN model using SGD under the coordination of a parameter server (PS). The local model updates are transmitted from the remote users to the PS over a RACH using a slotted ALOHA protocol. The PS collects the updates from the remote users, accumulates them, and sends central model updates to the users at regular time intervals. We refer to this setting as the RACH-FL setting. The RACH-FL setting crucially addresses the problem of jointly designing a (i) client selection and (ii) gradient compression strategy which addresses the communication constraints between the remote users and the PS when transmission occurs over a RACH. For the RACH-FL setting, we propose a policy, which we term the ''age-of-gradient'' (AoG) policy in which (i) gradient sparsification is performed using top-K sparsification, (ii) the error correction is performed using memory accumulation, and (iii) the slot transmission probability is obtained by comparing the current local memory magnitude minus the magnitude of the gradient update to a threshold. Intuitively, the AoG measure of ''freshness'' of the memory state is reminiscent of the concept of age-of-information (AoI) in the context of communication theory and provides a rather natural interpretation of this policy. Numerical simulations show the superior performance of the AoG policy as compared to other RACH-FL policies.

Linda M. Rini and Ingrid Provident
- Abstract
This small-scale pilot study was developed to examine the perceived occupational balance of graduate occupational therapy students and implement an education and coaching intervention to promote occupational balance for those who have difficulty achieving and maintaining it. Although literature provides many examples of interventions to facilitate stress relief in graduate students, this is the first to address the promotion of occupational balance in this effort, which has been identified as a student-reported need. A sequential explanatory mixed-methods approach was used to obtain quantitative and qualitative data on occupational therapy students' satisfaction with their balance of activity in all areas of occupation. The impact of that balance on stress levels and occupational satisfaction was examined utilizing an investigator developed scaled survey and The Canadian Occupational Performance Measure. Participants (N=22) were MSOT and OTD students from all academic years of their program. A six-week group education program was implemented. One additional 30-minute individual coaching session was held virtually with each student and the primary investigator to target individual goals. Survey data collected before the start of the educational series and again at its conclusion indicate an aggregate decrease in students' perceived stress (-0.85); an increase in perceived occupational performance (mean +1.26); and an increase in perceived occupational satisfaction (mean +2.10). The desired outcome of the intervention was to provide students with strategies to increase lifestyle balance to help manage some of the stresses of graduate academia, and ultimately increase students' health and wellness to promote retention and successful completion of graduate education.

- Abstract
The teacher has an important role in making pupils skilled in inquiry, viz guiding them to carry out inquiry steps in science learning. However, there are obstacles to applying online learning at primary school level, especially inquiry-based science. The purpose of this research is to analyse the application of inquiry in science learning, analyse the effectiveness of e-learning based on the 2020 at the Indonesian Ministry of Education and Culture guidelines, and identify obstacles to implementing e-inquiry science learning at the primary level. This study employed a descriptive qualitative approach. Sources of data were resource persons from 6 educational institutions including trainers, school supervisors, principals, teachers, Grade VI pupils, and their parents. The result showed the only a small number of teachers implemented on-line science-based inquiry learning and the effect of the learning was the utmost significance on student's achievement. However, most of primary school teachers have not applied inquiry-based methods in science learning. Several obstacles to implementing e-inquiry learning at the primary level were identified. These obstacles include the teachers did not understand how to develop an online inquiry model learning scenario, had low skills in using ICT, lack of support for ICT facilities and of e-learning inquiry learning guide, and had limited time.

- Abstract
Education plays a very important role in improving the quality of human resources. In higher education, students need learning that is innovative and not monotonous so that learning goals can be achieved. In this research, what will be discussed further is the development of learning methods by combining 2 methods, namely Cooperative Based Learning (CBL) with Problem-Based Learning (PBL) in the Advanced Financial Management course. This research method uses Pretest - Posttest Design. The data population is 711 students collected from 17 classes taking Advanced Financial Management courses at Putra Indonesia University YPTK Padang. The sampling technique uses probability sampling. The data that will be used as a sample are observations of 117 students collected from 3 classes. The CPBL method is implemented by grouping students into groups of 4-5 people to discuss each case in the material. Data will be analyzed based on the completeness of learning outcomes and calculating N-Gain. From the data processing, the results obtained were that by combining these 2 methods, it was successful in improving student learning outcomes and the students' completeness test scores were also proven to be very successful in being upgraded. The effectiveness of the collaboration between these 2 methods reaches the high category of the N-Gain test. This is a new variation in making learning calculations that use many formulas more challenging, increasing students' enthusiasm for learning and providing satisfactory learning results. This method is worth utilizing and can be used in all courses that involve calculations and case questions.

- Abstract
This study identifies and analyzes the processes and differences in distance learning implementation between city and village schools in Indonesia and Malaysia. Characteristics of students and teachers, distance learning facilities, ability to use technology, and parent's role in the learning process will be analyzed in depth. This research will simultaneously hypothesize the link between these factors and student learning independence. This research is a mixed methods research that combines qualitative research that using observation and interview techniques and quantitative methods that using questionnaire technique. This research was conducted on elementary school students in Indonesia and Malaysia located in rural and urban areas, with a total sample of 240 students ranging from low to high grades. Apart from students, as many as 60 school academics consisting of principals, teachers, and staff were also interviewed to obtain more comprehensive data and data triangulation. Quantitative data were analyzed using a qualitative-quantitative descriptive method where the qualitative statements in the questionnaire were converted into quantitative data, while qualitative data were analyzed using an interactive model mentioned by Miles & Huberman (2014). The study results show that the distance learning implementation between city and village schools experiences a slight difference with the rapid development of information technology. Of the four aspects studied, there are aspects in which village schools are superior to city schools. These four aspects are also investigated for their influence on student learning independence so that further research can be carried out regarding the correlation of these aspects to student learning independence.

Computer Science - Information Theory - Abstract
R\'enyi Information Dimension (RID) plays a central role in quantifying the compressibility of random variables with singularities in their distribution, encompassing and extending beyond the class of sparse sources. The RID, from a high perspective, presents the average number of bits that is needed for coding the i.i.d. samples of a random variable with high precision. There are two main extensions of the RID for stochastic processes: information dimension rate (IDR) and block information dimension (BID). In addition, a more recent approach towards the compressibility of stochastic processes revolves around the concept of $\epsilon$-achievable compression rates, which treat a random process as the limiting point of finite-dimensional random vectors and apply the compressed sensing tools on these random variables. While there is limited knowledge about the interplay of the the BID, the IDR, and $\epsilon$-achievable compression rates, the value of IDR and BID themselves are known only for very specific types of processes, namely i.i.d. sequences (i.e., discrete-domain white noise) and moving-average (MA) processes. This paper investigates the IDR and BID of discrete-time Auto-Regressive Moving-Average (ARMA) processes in general, and their relations with $\epsilon$-achievable compression rates when the excitation noise has a discrete-continuous measure. To elaborate, this paper shows that the RID and $\epsilon$-achievable compression rates of this type of processes are equal to that of their excitation noise. In other words, the samples of such ARMA processes can be compressed as much as their sparse excitation noise, although the samples themselves are by no means sparse. The results of this paper can be used to evaluate the compressibility of various types of locally correlated data with finite- or infinite-memory as they are often modelled via ARMA processes.

Computer Science - Information Theory - Abstract
In [1], the linked loop code (LLC) is presented as a promising code for the unsourced A-channel with erasures (UACE). The UACE is an unsourced multiple access channel in which active users' transmitted symbols are erased with a given probability and the channel output is obtained as the union of the non-erased symbols. In this paper, we extend the UACE channel model to the unsourced B-channel with erasures (UBCE). The UBCE differs from the UACE in that the channel output is the multiset union, or bag union, of the non-erased input symbols. In other words, the UBCE preserves the symbol multiplicity of the channel output while the UACE does not. Both the UACE and UBCE find applications in modeling aspects of unsourced random access. The LLC from [1] is enhanced and shown to outperform the tree code over the UBCE. Findings are supported by numerical simulations., Comment: 5 pages, 2 figures, accepted by ICASSP 2024

This paper introduces HAAQI-Net, a non-intrusive deep learning model for music audio quality assessment tailored for hearing aid users. Unlike traditional methods like the Hearing Aid Audio Quality Index (HAAQI), which rely on intrusive comparisons to a reference signal, HAAQI-Net offers a more accessible and efficient alternative. Using a bidirectional Long Short-Term Memory (BLSTM) architecture with attention mechanisms and features from the pre-trained BEATs model, HAAQI-Net predicts HAAQI scores directly from music audio clips and hearing loss patterns. Results show HAAQI-Net's effectiveness, with predicted scores achieving a Linear Correlation Coefficient (LCC) of 0.9368, a Spearman's Rank Correlation Coefficient (SRCC) of 0.9486, and a Mean Squared Error (MSE) of 0.0064, reducing inference time from 62.52 seconds to 2.54 seconds. Although effective, feature extraction via the large BEATs model incurs computational overhead. To address this, a knowledge distillation strategy creates a student distillBEATs model, distilling information from the teacher BEATs model during HAAQI-Net training, reducing required parameters. The distilled HAAQI-Net maintains strong performance with an LCC of 0.9071, an SRCC of 0.9307, and an MSE of 0.0091, while reducing parameters by 75.85% and inference time by 96.46%. This reduction enhances HAAQI-Net's efficiency and scalability, making it viable for real-world music audio quality assessment in hearing aid settings. This work also opens avenues for further research into optimizing deep learning models for specific applications, contributing to audio signal processing and quality assessment by providing insights into developing efficient and accurate models for practical applications in hearing aid technology.

Rini PL and Gayathri KS
- Abstract
Background: Dementia is a cognitive decline that leads to the progressive deterioration of an individual's ability to perform daily activities independently. As a result, a considerable amount of time and resources are spent on caretaking. Early detection of dementia can significantly reduce the effort and resources needed for caretaking. Aims: This research proposes an approach for assessing cognitive decline by analysing speech data, specifically focusing on speech relevance as a crucial indicator for memory recall. Methods & Procedures: This is a cross-sectional, online, self-administered. The proposed method used deep learning architecture based on transformers, with BERT (Bidirectional Encoder Representations from Transformers) and Sentence-Transformer to derive encoded representations of speech transcripts. These representations provide contextually descriptive information that is used to analyse the relevance of sentences in their respective contexts. The encoded information is then compared using cosine similarity metrics to measure the relevance of uttered sequences of sentences. The study uses the Pitt Corpus Dementia dataset for experimentation, which consists of speech data from individuals with and without dementia. The accuracy of the proposed multi-QA-MPNet (Multi-Query Maximum Inner Product Search Pretraining) model is compared with other pretrained transformer models of Sentence-Transformer. Outcomes & Results: The results show that the proposed approach outperforms the other models in capturing context level information, particularly semantic memory. Additionally, the study explores the suitability of different similarity measures to evaluate the relevance of uttered sequences of sentences. The experimentation reveals that cosine similarity is the most appropriate measure for this task. Conclusions & Implications: This finding has significant implications for the early warning signs of dementia, as it suggests that cosine similarity metrics can effectively capture the semantic relevance of spoken language. The persistent cognitive decline over time acts as one of the indicators for prevalence of dementia. Additionally early dementia could be recognised by analysis on other modalities like speech and brain images.

Farida Jamil, Anis, Siswono, Tatag Yuli Eko, and Setianingsih, Rini
- Abstract
The current research trend of metacognitive regulation has shifted from an individual to a social context. One such social context is collaborative problem-solving. Interaction between group members is an essential factor in completing collaborative problems. Metacognitive regulation is divided into four forms based on the interaction in collaborative problem-solving. This study aims to analyze the emergence and form of metacognitive regulation in groups that are more and less successful at solving geometric problems collaboratively. Each group consists of two undergraduate students who have taken geometry courses. The group tries to solve geometry problems in the form of proof problems. This study examines how metacognitive regulation emerges in group discussion activities. The emergence of metacognitive regulations was identified through student utterances when discussing in groups. In addition, interview data support researchers in exploring metacognitive regulation carried out by groups. This study also identifies forms of metacognitive regulation that occur when groups interact. The study results showed differences in the metacognitive regulation activity in four aspects: orientation, planning, monitoring, and evaluation. The more successful group has a form of co-constructed social metacognitive regulation. In contrast, the less successful group has a form of ignored social metacognitive regulation.

- Abstract
Facing the post-COVID-19 pandemic, teachers need to enhance technology in their teaching and learning process, especially in delivering the materials for the students. As digital natives, students are familiar with technology, and it makes them excited in learning English materials. Academic writing materials are complex because it involves expressing ideas carefully elaborated, and well-supported, logically sequenced, rigorously reasoned, and tightly stitched together. Powtoon is one of the solutions to make the materials more interesting and understandable for the students in academic writing class. This study aims to know the students' perspectives and challenges about the use of Powtoon as digital learning media to improve writing skills. The subjects are 37 students in English Department in one of the state universities in Indonesia. The method is qualitative by using questionnaire, interview, and documentation. It is found that the students have positive perceptions (76.92%) on the use of Powtoon as digital learning media to improve writing skills. Hence, Powtoon is recommended as digital learning media to improve the students' writing skills. However, the motion of the animation could distract student's concentration in understanding the materials. Apart from that, students still need to ask directly to the teacher if they have not really understood about the materials presented using Powtoon.

- Abstract
Creative thinking skills are recognised 21 century skills. This study aimed to determine whether students' creative thinking skills in biochemistry courses are improved through scaffolding-based problem-based learning. The study employed a mixed methods approach with a sample of 113 chemistry education programme students at Jambi University. An observation sheet instrument was used to gauge students' creative thinking skills during learning, test questions were used to gauge them after the implementation of Problem Based-learning, and an interview instrument was used to see how students responded once PBL learning had been implemented. Descriptive statistical testing techniques were applied to data between classes. It was found that there were significant differences in students' creative thinking skills after scaffolding-based PBL learning had been carried out. The biochemistry learning process was found to be conducive to scaffolding in problem-based learning. Providing scaffolding in problem-based learning also has a positive impact on students because this study proves that students become more active learners in education because the problem-solving process requires students to express opinions and exchange ideas.

Electrical Engineering and Systems Science - Signal Processing ,Computer Science - Information Theory - Abstract
In this paper, we investigate the problem of recovering the frequency components of a mixture of $K$ complex sinusoids from a random subset of $N$ equally-spaced time-domain samples. Because of the random subset, the samples are effectively non-uniform. Besides, the frequency values of each of the $K$ complex sinusoids are assumed to vary continuously within a given range. For this problem, we propose a two-step strategy: (i) we first lift the incomplete set of uniform samples (unavailable samples are treated as missing data) into a structured matrix with missing entries, which is potentially low-rank; then (ii) we complete the matrix using a weighted nuclear minimization problem. We call the method a \emph{ weighted lifted-structured (WLi) low-rank matrix recovery}. Our approach can be applied to a range of matrix structures such as Hankel and double-Hankel, among others, and provides improvement over the unweighted existing schemes such as EMaC and DEMaC. We provide theoretical guarantees for the proposed method, as well as numerical simulations in both noiseless and noisy settings. Both the theoretical and the numerical results confirm the superiority of the proposed approach.

Computer Science - Robotics ,Electrical Engineering and Systems Science - Systems and Control - Abstract
LiDAR-camera fusion is one of the core processes for the perception system of current automated driving systems. The typical sensor fusion process includes a list of coordinate transformation operations following system calibration. Although a significant amount of research has been done to improve the fusion accuracy, there are still inherent data mapping errors in practice related to system synchronization offsets, vehicle vibrations, the small size of the target, and fast relative moving speeds. Moreover, more and more complicated algorithms to improve fusion accuracy can overwhelm the onboard computational resources, limiting the actual implementation. This study proposes a novel and low-cost probabilistic LiDAR-Camera fusion method to alleviate these inherent mapping errors in scene reconstruction. By calculating shape similarity using KL-divergence and applying RANSAC-regression-based trajectory smoother, the effects of LiDAR-camera mapping errors are minimized in object localization and distance estimation. Designed experiments are conducted to prove the robustness and effectiveness of the proposed strategy.

Computer Science - Information Theory ,Computer Science - Multimedia - Abstract
The A-channel is a noiseless multiple access channel in which users simultaneously transmit Q-ary symbols and the receiver observes the set of transmitted symbols, but not their multiplicities. An A-channel is said to be unsourced if, additionally, users transmissions are encoded across time using a common codebook and decoding of the transmitted messages is done without regard to the identities of the active users. An interesting variant of the unsourced A-channel is the unsourced A-channel with erasures (UACE), in which transmitted symbols are erased with a given independent and identically distributed probability. In this paper, we focus on designing a code that enables a list of transmitted codewords to be recovered despite the erasures of some of the transmitted symbols. To this end, we propose the linked-loop code (LLC), which uses parity bits to link each symbol to the previous M symbols in a tail-biting manner, i.e., the first symbols of the transmission are linked to the last ones. The decoding process occurs in two phases: the first phase decodes the codewords that do not suffer from any erasures, and the second phase attempts to recover the erased symbols using the available parities. We compare the performance of the LLC over the UACE with other codes in the literature and argue for the effectiveness of the construction. Our motivation for studying the UACE comes from its relevance in machine-type communication and coded compressed sensing., Comment: 5 pages, 4 figures, to be published in the 31st European Signal Processing Conference, EUSIPCO 2023

Abstract Brown and beige adipocytes can be activated by β-adrenergic agonist via cAMP-dependent signaling. Performing RNA-sequencing analysis in human cervical area-derived adipocytes, we found that dibutyryl-cAMP, which can mimic in vivo stimulation of browning and thermogenesis, enhanced the expression of browning and batokine genes and upregulated several signaling pathway genes linked to thermogenesis. We observed that the expression of inhibitor of DNA binding and cell differentiation (ID) 1 and particularly ID3 was strongly induced by the adrenergic stimulation. The degradation of ID1 and ID3 elicited by the ID antagonist AGX51 during thermogenic activation prevented the induction of proton leak respiration that reflects thermogenesis and abrogated cAMP analogue-stimulated upregulation of thermogenic genes and mitochondrial complex I, II, and IV subunits, independently of the proximal cAMP-PKA signaling pathway. The presented data suggests that ID proteins contribute to efficient thermogenic response of adipocytes during adrenergic stimulation.

Osteoarthritis, a prevalent form of arthritis linked to bone degeneration, particularly affects the elderly population. In Indonesia, its prevalence rises with age, impacting various ethnic groups, notably women, and leading to substantial disability in individuals aged 65 and older. Vigilance is essential against potential complications like gastritis, bleeding, or kidney issues resulting from prolonged use of non-steroidal anti-inflammatory drugs (NSAIDs). The condition's pathophysiology involves joint aging, injuries, excessive use, genetic predisposition, obesity, and hormonal changes. Its clinical signs develop gradually but can accelerate due to injuries or joint strain, significantly reducing patient productivity and life quality. Managing osteoarthritis involves non-drug approaches like education, physical and exercise therapy, followed by medication and supportive devices. The treatment selection depends on severity and the number of affected joints, aiming to control pain, improve joint function, ease physical limitations, and hinder disease progression and complications. Prompt intervention with suitable modalities aligned with the patient's condition offers a favorable prognosis. Factors like muscle weakness, obesity, and depressive disorders can exacerbate osteoarthritis outcomes. Comprehensive management addressing these factors can significantly improve the prognosis and enhance the patient's quality of life.

Abstract Coccidiosis poses a significant threat to the poultry industry, with synthetic antibiotics and disinfectants being the primary tools for control. This study investigated the potential of Piper betle L essential oil (PBEO) as a natural alternative against Eimeria tenella, one of the most pathogenic Eimeria species affecting poultry. Our findings revealed that PBEO exhibits significant anticoccidial effects through two primary mechanisms: (i) oocysticidal activity by disintegrating oocyst walls and (ii) inhibition of the sporulation process. PBEO demonstrated oocysticidal activities ranging from 8.67 to 95.33% across concentrations from 0.04 to 40%. Notably, at 72 h post-incubation, a 0.04% PBEO concentration significantly reduced the number of sporulated oocysts (P ≤ 0.05) to 71.67%, showing effects comparable to those of formalin. PBEO reduced 50% of oocyst sporulation (IC50) in the concentration of 1.31% at 72 h. Gas chromatography-mass spectrometry (GC-MS) identified the primary constituents of PBEO, including eugenol, beta-caryophyllene, and other key compounds, collectively constituting 96% of the oil. This research underscores the potential of PBEO as a natural anticoccidial agent and lays the groundwork for further studies aimed at identifying, isolating, and developing active compounds that may specifically target the sporogony process in coccidian parasites.

This study has aimed to determine the potential use of catechins derived from gambier as an anti-microbial raw material in the manufacture of hand washing liquid soap. The study started from the purification process of catechins from gambier and continued with the addition of gambier to the soap formula looking for hand washing. In this study, there were some difficulties in obtaining catechin extracts that could dissolve in water due to the character of catechins that did not dissolve completely in water. Therefore, the optimization of the catechin extraction process is optimized first. The catechin extraction process was carried out in two ways, namely by using a homogenizer at a speed of 15000 rpm for 30 minutes and a reflux process with hot water (temperature 70 degrees Celsius) for one hour. It was found that the concentration of catechin dissolved in water both in the homogenizer and reflux results was relatively the same, therefore for the manufacture of hand washing liquid soap, the process with the reflux technique would be recommended because of the cheaper operational costs.

A food self-heater is a device designed to rapidly heat food by the utilization of exothermic or endothermic reactions. To yet, a food self-heater with a dedicated scent feature has not been developed. The fragrance utilized is derived from residual tangerine peel components. The objective of this study is to investigate the variations in the concentration of the limonene compound in essential oil extracted from tangerine peel, specifically examining the impact of tangerine peel wilting. Additionally, the study intends to identify the most effective food self-heating method by incorporating tangerine peel powder as an aromatic component in the self-heating process. The present study employed a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments employed in this study encompassed varying durations of withering time for tangerine peel, denoted as A (0 hours), B (6 hours), C (12 hours), D (24 hours), and E (48 hours). The research findings indicated that the duration of drying tangerine peels had a notable impact on various factors including water content, yield, pH, color, duration for the aromatic self-heating meal to attain the optimal temperature, and aroma. However, no significant influence on limonene levels was seen. Based on the duration required for the aromatic food self-heater to attain the optimal temperature and the organoleptic aroma, treatment D (24-hour withering of tangerine peel) demonstrates the highest efficacy. This treatment exhibits a time frame of approximately 4.5 minutes for the aromatic food self-heater to reach the optimum temperature, accompanied by a fragrance rating of 4.2 in the organoleptic analysis.

Antiviral peptides (AVPs) are small molecules that inhibit the replication of viruses in living cells. AVPs are being investigated as potential alternatives to traditional antiviral drugs. The development of novel antiviral agents is of the highest concern because some traditional antiviral medications can be ineffective and lead to resistant viruses emergence. We conducted a bibliometric study on the global distribution of AVP research to comprehend the trends and patterns in the field. For this analysis, we retrieved data from the Scopus database on AVP-related publications from 1951 to 2022, including the number of publications, citations, and authors. Overall, 10,279 papers were published, with an annual average of 146 publications. The United States released the most documents, followed by China, Germany, and the United Kingdom. Since 2001, there has been a substantial increase in global publications on AVPs, with prominent themes including virology, genetics, protease inhibitors, polypeptide antimicrobial agents, and viral entry. This bibliometric analysis can be used to guide future research in this field.

Men doubles badminton has been growing rapidly, requiring a study on match characteristics and physiological responses. To arrange an effective training program design and periodization, understanding the athlete physiological responses and match characteristics are necessary. This study examined the traits of male doubles badminton players according to their court positions (front and back). Laboratory tests and on-court simulations were administered in the study. Participants were athletes from an Indonesian elite badminton club aged 17-19 years. Measurements included anthropometrics, VO2max, blood lactic acid, heart rate, energy expenditure, and match statistics. Standardized equipment was used to measure the anthropometry, while treadmill test with gas analysis was used to measure VO2max. A portable analyser measured blood lactate during simulated matches, while Polar RC 3 GPS devices tracked heart rate and energy expenditure. Video analysis with Go Pro Hero 3+ cameras collected match statistics. The average VO2max was 56.4±5.7 ml/kg/min for both front and back players. Physical responses during gameplay showed significant differences (P0.005), with back players showing higher %HR max, calorie expenditure, and lactic acid levels than front players. Match statistics showed that back players had higher smashes (4.2±1.8) and unforced errors (6.3±7.3) (P0.005), while front players had higher drives (4.4±1.3) and net shots (4.2±1.2) (P0.005). Front and back players had different activity loads, as shown by maximum heart rate and stroke distributions, affecting lactic acid levels. Back players had higher maximum heart rates and more smashes than front players, indicating higher metabolic demands. These findings help tailor men doubles badminton position-specific trainings. The unique demands of each court position can be considered when designing more targeted and effective training programs using physiological adaptation and match data.

A recommendation system helps collect and analyze user data to generate personalized recommendations for users. A recommendation system for movies has been implemented, considering the vast number of available films and the difficulty users face in finding movies that match their interests. One popular recommendation method is Collaborative Filtering (CF). Although widely applied, CF still has issues. Basic CF uses overlapping user data in evaluating items to calculate user similarity. This study aims to build a collaborative filtering recommendation system using clustering techniques to group users with similar interests into the same clusters. The next step in CF application is to gather recommendation candidate items by finding users with a high level of similarity to the target user. Subsequently, user pattern analysis is carried out by applying association rule mining to predict hidden correlations based on frequently watched items and the ratings given to those movies. This study uses rating data and movie data from the Movielens website. The evaluation of the recommendation results is measured using precision, recall, and f-measure. The evaluation results show that the proposed recommendation system achieves a hit rate of 95.08%, a precision of 81.49%, a recall of 98.06%, and an f-measure of 87.66%.

Background: Reproductive health, crucial for public health and sustainable development, encompasses family planning and contraceptive use. However, global disparities persist in the adoption of family planning, highlighting the need for a comprehensive understanding of the complex factors shaping these reproductive health choices. Materials and Methods: Following Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines, we conducted a systematic search of the Scopus, ScienceDirect, PubMed, Web of Science, and ProQuest databases from July to August 2023. Inclusive criteria covered various study designs and populations, ranging from individuals to communities, and encompassed sociocultural factors. The review included open access articles published between 2018 and 2023, utilizing a combination of the keywords: Family planning determinants, Contraceptive use factors, Sociocultural factors in family planning, Individual-level influences on family planning, and Factors affecting contraceptive choices. Results: Data from 25 selected studies underscore the critical influence of determinants at both individual and community levels in shaping family planning behaviors. Key drivers at the individual level included education, age, knowledge, and attitudes. At the community level, factors such as geographical disparities and healthcare accessibility played pivotal roles. Sociocultural determinants, including media exposure, gender norms, and spousal dynamics, highlighted the need for culturally sensitive strategies. Conclusions: Advancing equitable family planning requires education, improved access, peer influence, and the active participation of husbands and male partners. Comprehensive programs should bridge the gap between knowledge and action, reduce disparities, and ensure equal access to contraception. Context-specific research and evaluating interventions are crucial steps toward achieving global reproductive health objectives.

Elderly refers to individuals who have reached the final stage of life, namely 60 years old and above. Physiologically, the elderly will experience various declines in body functions. The decline in cognitive function is among the most common in the elderly. The incidence of cognitive decline in the elderly in Indonesia is relatively high, which is as much as 32.4%, and is most vulnerable at the age of 65 years. Cognitive impairment can cause older adults to have difficulty in doing daily activities (bathing, dressing, washing, cooking), managing finances, getting lost on the road, and other disturbances that make the elderly less independent and confident, then tend to withdraw from social activities. The disturbances can also lead to anxiety disorders and depression. This study aims to determine the profile of cognitive function in the elderly at Palembang Nursing Homes. This cross-sectional study involves all elderly individuals in Palembang City Nursing Homes who meet the inclusion-exclusion criteria. The Indonesian version of the Montreal Cognitive Assessment (MoCA-Ina) was used to assess cognitive function. In this study, as many as 69 elderly (87.34%) had experienced a decline in cognitive function. Then, the dominant characteristics in the group that experienced a decrease in cognitive function were >90 years old (100%), women (91.38%), college graduates (100%), never worked (100%), had a history of stroke (92.86%), did not remember or did not know about cognitive impairment history in the family (93.33%). Delayed recall was the aspect that experienced the most disruption (96.2%). This study has revealed that the prevalence of cognitive impairment in Palembang Nursing Homes is exceptionally high. Therefore, it is imperative to implement routine screenings to identify early cognitive impairment in the elderly to provide immediate treatment.
