Purpose: To evaluate the dimensional accuracy of implant impressions obtained using five different tray types and two techniques. Materials and Methods: A partially dentate maxillary Kennedy Class II model was created as a reference model through 3D printing. Then, implant analogs 4.3 mm in diameter were placed at the first premolar, first molar, and second molar sites. Five types of trays were used to create impressions: (1) metal stock trays, (2) plastic stock trays, (3) custom trays fabricated using liquid crystal display (LCD), (4) custom trays fabricated using fused deposition modeling (FDM), and (5) custom trays fabricated using urethane dimethacrylate (UDMA) resin. Open and closed tray techniques were also compared. In total, 150 impressions were obtained. The reference model and impressions were scanned using a laboratory scanner. Additionally, the positional and angular deviations of implants with different tray types and techniques were evaluated using the superimposition method. Results: There was no statistically significant difference (P > .05) between the impression accuracy with the different tray types and impression techniques. The angular deviations with plastic and UDMA trays were greater than those with metal, FDM, and LCD trays. Angular deviation at the second molar was greater when using closed plastic trays compared to open plastic trays. The highest and lowest positional deviations were observed at the first molar implant with an open plastic tray impression (mean ± SD of 62.46 ± 28.54 mm) and a closed LCD tray impression (36.59 ± 29.93 mm). The greatest angular deviation was observed with an open FDM tray impression at the first premolar implant (0.067 ± 0.024 degree), and the lowest angular deviation was observed with a closed metal stock tray impression at the second molar implant (0.039 ± 0.025 degree). Statistical differences were detected using the Mann-Whitney U test for paired groups and the Kruskal-Wallis test for groups with more than three comparisons (P > .05). Conclusions: Plastic and metal stock trays or conventional and 3D-printed custom trays can be used to obtain implant impressions for maxillary partially edentulous arches with similar dimensional accuracy. The five tray types and two techniques may be safely used to obtain impressions of partially edentulous maxillary arches with three implants. [ABSTRACT FROM AUTHOR]

We examined visually impaired individuals' impression management strategies through Goffman's dramaturgical perspective. Consistent with the biomedical model of disability and ableism, participants managed appearance, suppressed emotions, and strategically asked for help in the frontstage to combat stereotypes, present as less of a burden, and serve as low-vision ambassadors. Backstage, participants expressed emotion privately, engaged in solitary pursuits, and coped through support groups and therapy. While therapy helped some resist ableist ideology, even backstage many participants struggled to decompress and find peace. Thus, a true backstage does not apply to people who are oppressed, as frontstage challenges constrained participants' backstage coping. [ABSTRACT FROM AUTHOR]

Nowadays, numerous sporting events of diverse nature take place every week. This highlights the importance of conducting studies to assess their quality and determine the best event to participate in. Obtaining this information will allow organisers and managers to improve the services offered in order to meet the growing demands of users. The purpose of this study was to analyse the perception of quality by the athletes who attended and participated in the Campeonato de España de Selecciones Autonómicas de Balonmano 2022 (CESA BM 2022), with a gender breakdown. The sample consisted of 514 athletes. Data collection was carried out telematically by means of an online survey using the "Encuestas" tool of the University of Murcia. Perceived quality elements were assessed, as well as the importance of performance, segregated by gender and category of participation. The main results revealed that for athletes, the best rated dimension was "Future intentions", while the worst was "Perceived value". Some conclusions drawn from this study include that the female gender of the sample perceived higher quality compared to the male gender. It was also observed that players in the infantile category perceived higher quality than cadets and juniors, and statistically significant differences were also found between the various elements of the study.

Introduction: In every prosthetic treatment, the final purpose of the restoration is to restore function and esthetics for the patient, respecting biology and anatomical parameters. Regarding full coverage restorations, there are some factors to take into consideration: like the finish line (chamfer, shoulder, featheredge, etc.), the management of the provisional restoration and tissue healing, the material for the final restoration, and the impression technique. All these aspects will determine the treatment process and its possible results. In recent years, vertical preparation and more specifically biologically oriented preparation technique has generated great interest since its introduction in prosthodontics, changing the periodontal tissues, and providing long‐term stability. Materials and Methods: With this technique, the objective is to change the position of the gingival margin, moving it more apically or coronally, depending on the modifications of the provisional. The relining of the provisional is a fundamental step of this technique: the intrasulcular part of the provisional is modified giving a new emergence profile and providing an augmentation of the tissue in the healing process. Discussion: In vertical preparation, there is no predetermined margin. The dental technician should position the finish line more apically or coronally, depending on the depth of the sulcus and on the esthetic needs. Ceramic restorations should not invade the epithelial attachment, otherwise it may cause biological and mechanical problems, repetition of the impression, and of the crown restoration, which lead to increased clinical and laboratory time usage as well as expenses. One challenge is communicating the shape and contour of the temporary restoration to the dental lab to ensure accurate information for the final restoration. Conclusion: Finally, the objective of this article is to describe a technique for transferring all necessary information of the provisional and obtaining a predictable result for the final restoration by using an intraoral scanner system and the fabrication of two 3D printed prototypes. One for the final volume of the crowns and the other for the finish line position. Clinical Significance: The fabrication of 3D printed prototypes allows for a more predictable final restoration, reducing possible communication errors between clinician and technician when restoring with biologically oriented preparation technique. In any esthetic treatment where the restoration does not have a predetermined margin, it is possible with this additional clinical step to provide a more esthetic outcome. [ABSTRACT FROM AUTHOR]

Introduction: The use of digital dentistry is rapidly increasing in prosthodontics. However, most dental students are not familiar with applying digital technologies in dental clinics. Thus, the aim of the current study was to assess the perception of dental students at different educational years towards digital impressions in comparison to conventional impressions. Materials and Methods: A cross‐sectional questionnaire‐based study was conducted on various educational years of dental students in the College of Dentistry, Imam Abdulrahman Bin Faisal University, between February and April 2023. The students had performed at least one intraoral scan (Trios 3shape) and another conventional polyether impression for phantom casts/patients. The questionnaire assessed students' perceptions of digital impressions using a 5‐point scale ranging from strongly agree to strongly disagree. Mann–Whitney U and Kruskal–Wallis tests were used to compare students' perceptions of digital impressions according to gender and educational year, respectively. Results: The study included 122 students. About 55% were females with a mean (SD) age = 22.51 (3.36). Most students thought that digital impressions are faster and more user‐friendly compared to conventional impressions. Significantly more female students thought that the handpiece was too big for intraoral use (p = 0.04) and that the process of the software was time‐consuming and complicated. In general, higher educational year students were more satisfied with the digital impressions than lower educational year students. Conclusions: Digital impressions were perceived by most students as being faster and easier than conventional ones. However, male students and those with higher educational years showed better perception of digital impression. [ABSTRACT FROM AUTHOR]

Purpose – The study aims to determine whether a relationship exists between the potential significance of corporate controversies for stakeholders and how organisations respond to them in their annual and sustainability reports. Design/methodology/approach – This paper employs content analysis on annual and sustainability reports of 48 listed companies from the Refinitiv database. The logit regression was used to estimate the model. Findings – The study revealed that the main factors increasing the probability of a controversial issue being addressed in a corporate report are the controversy’s potential significance, companies’ financial performance and lawsuits. Research limitations/implications – Our study has three major limitations. These are a relatively small sample of companies and reports, focusing on disclosures made in corporate reports and omitting other channels of communication, for example, social media, and a certain amount of subjectivity in the process of coding information. Social implications – Former studies show that corporations face a serious risk of their hypocritical strategies becoming too evident for stakeholder groups. Our findings suggest that the risk is already materialising and may undermine the idea of CSR and sustainability reporting. Originality/value – Our research focuses on high-profile adverse incidents widely reported in the media, the omission of which from corporate reports seems to constitute a particular case of organised hypocrite. It also demonstrates that companies use an impression management strategy to defuse adverse publicity and that major controversies cause minor ones to be omitted from their reports.

Objective: This study investigated how the number of images collected for digital measurements in dentistry affects accuracy compared with traditional methods. Methods: A Frasaco maxillary model was scanned using a SHINING 3D AutoScan-DS-MIX dental 3D scanner to create an STL file. The maxilla was molded 10 times using polyvinyl siloxane (Zhermack Elite HD+) to produce plaster models, which were scanned with the same reference scanner to generate 10 STL files. The Frasaco model was scanned 10 times, capturing images in intervals of 800–1000, 1000–1200, and 1200–1500 using a 3Shape TRIOS 3 intraoral scanner, creating additional STL files. These were analyzed with reverse engineering software. Results: The most accurate measurements were obtained using 1200–1500 images. Conventional impression techniques performed significantly worse. There was a significant difference between the groups Digital 1200–1500 and Plaster (p < 0.001) and between Digital 800–1000 and Plaster (p = 0.007). No significant difference was found when the digital groups were compared among themselves. There was also no significant difference between the Plaster and Digital 1000–1200 groups. To compare precision values that were normally distributed across three or more methods, a one-way ANOVA was used. Trueness values that were not normally distributed with three or more methods were compared employing the Kruskal–Wallis test. Conclusions: Different image counts affect digital measurement accuracy. The most accurate measurements were obtained when collecting 1200–1500 images. Conventional impression techniques were shown to perform significantly worse than digital impression.

Background. This study assessed the potential efficacy of donepezil in treating autism spectrum disorder (ASD), a neurodevelopmental condition characterized by social communication difficulties and repetitive behaviors. Donepezil, primarily used to treat Alzheimer’s disease as an acetylcholinesterase inhibitor, has gained attention as a potential treatment for ASD symptoms. Methods. Following PRISMA guidelines, a systematic review was conducted to investigate the effects of donepezil on individuals with ASD. Outcome measures assessed various aspects of ASD, including language skills, executive function, behavior, and core symptoms. Nine studies were identified, including four randomized controlled trials (RCTs), three retrospective studies, one open-label trial, and one case report. Results. One RCT reported significant improvements in expressive and receptive language skills, especially in younger children. Another study combining donepezil with choline supplementation showed enhanced receptive language skills, particularly in younger participants. An open-label trial indicated improved rapid eye movement sleep patterns in autistic children treated with donepezil. Several retrospective studies reported improvements in behavioral symptoms, such as aggression and hyperactivity. However, other RCTs did not find statistically significant improvements in executive functioning. Conclusion. In general, donepezil use in ASD demonstrates promise in specific areas, notably language development and behavioral symptom management. However, the results are contradictory, requiring further research to clarify its role, optimal dosing, long-term effects, and potential side effects in individuals with ASD. Practical Implications. Donepezil can be used to improve the clinical global impression and language skills of people with ASD. [ABSTRACT FROM AUTHOR]

An esthetic peri‐implant soft tissue contour is a critical element of the success of implant restorations in the esthetic zone. Once the optimal transmucosal soft tissue profile is formed, it needs to be accurately replicated on the master cast. This clinical technique involves the utilization of a silicone putty positioning index placed in the patient's mouth to accurately duplicate the external contour of teeth and soft tissue. By combining this positioning index with the implant‐supported interim crown, the 3D‐printed initial cast, which was used to fabricate the interim crown, can be conveniently and efficiently transformed into a definitive master cast.

Aim: The aim of this study was to compare the accuracy of full‐arch conventional implant impressions using two different materials (A‐silicone and polyether) to full‐arch digital implant impressions produced from two intraoral scanning devices. Materials and Methods: A master model was fabricated representing an edentulous mandible with four implants with internal connection placed at the sites of canines and first molars. The anterior implants were parallel to the residual ridge, while the two posterior implants had an angulation of 15° to the distal and 15° to the lingual respectively. The conventional technique was performed with open‐tray of non‐splinted impression copings. Two different impression materials were used, A‐silicone and polyether at monophase medium body consistencies. The digital impressions were obtained with the use of two different intraoral scanners, after the connection of scan bodies. A total of 10 impressions were produced for each of the four experimental groups. The conventional models as well as the master model were digitized using a high‐resolution laboratory scanner. The STL files of the models and of the intraoral impressions were imported in a powerful superimposition software, for the conduction of measurements in pairs of files. The software calculated the 3D deviations, as well as the linear and angular displacements among scan bodies at the digital files. For "trueness" measurements every STL file of each experimental group was superimposed to the digital master model, while for "precision" measurements all STL files of each experimental group were superimposed to each other. Results and Conclusions: The accuracy of full arch mandibular implant impressions was influenced both by the impression technique used (conventional vs. digital) and the impression material used (A‐silicone vs. polyether) or the intraoral scanner used (Trios vs. Heron).In terms of "trueness," A‐silicone showed the highest impression accuracy with the lowest deviation values, followed by polyether and Trios, but the differences between the three groups were in the majority not statistically significant. Heron showed statistically lower accuracy results in all measurements compared to the other groups.In terms of "precision", conventional impressions with the use of A‐Silicone or polyether were statistically significantly superior to digital impressions with either scanner. A‐Silicone and polyether showed no statistically significant difference between them. [ABSTRACT FROM AUTHOR]

Ce sondage est paru dans Art-Rite, une revue proche du fanzine, centrée sur les avant-gardes de la scène new-yorkaise, publiée entre 1973 et 1978. Ce numéro 14, daté de 1977, est entièrement consacré au phénomène alors grandissant et foisonnant du livre d’artiste. Il y est ainsi question de la rencontre de l’art avec le monde du livre. Des artistes, éditeurs, critiques, bibliothécaires, etc. ont répondu très librement à l’appel des éditeurs à décrire leur rapport aux livres d’artistes. Les réponses recueillies permettent de donner une idée globale des préoccupations, perceptions, productions et usages de cette forme d’art – et plus largement de la relation entre art et livre à une époque où les médias se multiplient. L’ensemble interroge sur ce que le livre implique pour le monde de l’art, et les changements qu’il induit ou pourrait induire. Certaines des réponses dénotent la revendication ouvertement politique de cette forme d’art alternative qui contrecarre le marché de l’art et sa mainmise en rendant une certaine liberté aux artistes. Le livre est en effet un véhicule d’idées, portatif, plus accessible car banal, multiple, peu cher et relativement facile à produire. Derrière cette utopie permise par l’économie du livre, apparaît aussi en creux un portrait de l’art dans l’Amérique des années 1970 et de ses préoccupations à l’aube de l’arrivée des technologies numériques – l’idée d’une fin du livre est esquissée. La notion d’artiste, présente dans l’appellation « livres d’artistes », est remise en cause comme son implication dans la société. Car beaucoup y voient une perspective de populariser l’art.Pourtant la diversité des réponses illustre l’ambivalence du médium. Les affirmations se contredisent, faisant valoir toute la complexité du livre qui ne reste pas moins un objet, une marchandise – certes différente d’une œuvre d’art unique – donc le produit d’une industrie avec ses propres règles. Ainsi, certains pointent les difficultés techniques et économiques d’une forme d’art qui peine à trouver son public et son marché par manque de moyens et de diffusion, malgré toutes les initiatives émergentes. D’autres rappellent aussi leur lien au livre artisanal ou unique – cependant politiquement nié par la majorité. Car même avec la reproduction mécanisée, le livre bricolé avec les moyens du bord reste plus proche de l’œuvre d’art artisanale que de l’édition fabriquée et diffusée professionnellement, surtout en matière de distribution.Ce sondage révèle une grande pluralité d’usages : le livre comme réflexivité, trace, ou enregistrement, documentation d’une œuvre principale, et le livre comme création, image, montage, écriture. Pour beaucoup, utiliser le livre c’est reprendre une forme historique, à la frontière entre le design, la littérature, l’essai et le livre d’art. C’est aussi s’inscrire dans un format séquentiel imposant une structure à explorer, déconstruire ou conserver. Pour résumer : un vaste champ d’expérimentation.

Purpose: To compare the quality of complete dentures and quality of life of participants rehabilitated by using TENS (Transcutaneous electric nerve stimulation) facilitated impression making with manual impressions. Material and methods: Ten completely edentulous participants were enrolled in the crossover, pilot study. Participants were randomized in 2 groups. Five participants in each group were rehabilitated by dentures fabricated with TENS facilitated definitive impression technique (group T) and conventional impression technique (group C). In group T, Bioelectric border molding was done for the participants, that uses electric stimulation of the nerves supplying the muscles. In group C, incremental border molding using modeling plastic impression compound was carried out. Participants in each group used the dentures for 3 months. After 3 months, OHIP-EDENT questionnaire responses were obtained from the participants to observe the oral health related quality of life. A dental specialist recorded denture quality by Kapur scoring criteria. After one month wash period, the treatment was swapped between the groups. OHIP-EDENT scores and Kapur score were recorded for the alternate dentures after 3 months of use. Descriptive analysis was followed by Mann Whitney test to compare the overall scores between group T and group C for OHIP-EDENT, the scores for individual domains of OHIP-EDENT, and Kapur score for denture evaluation (α = 0.05). Results: The overall OHIP-EDENT scores within each domain were less in group T when compared with the scores in group C and Kapur score for group T was more than group C. The difference was statistically significant i.e. P = 0.002 & 0.003 respectively. Conclusions: Less OHIP-EDENT scores in group T imply better perception of quality of life of individuals due to better performance of stomatognathic system. The higher Kapur scores in group T signifies better quality of dentures when TENS was used for definitive impression making.

Purpose: To study the influence of insertion depth and implant angulation on the 3D trueness of models obtained with different impression techniques. Materials and Methods: Four different reference models (model 1: parallel, depth of 1.5 mm; model 2: parallel, depth of 4 mm; model 3: 20-degree angle, depth of 1.5 mm; and model 4: 20-degree angle, depth of 4 mm) of partially edentulous maxillae were generated by altering implant angulations and subgingival depths. All scans of reference models were done with a laboratory scanner, and obtained data were exported into standard tessellation language format to be used as virtual reference images. Impressions were obtained from each reference model via three conventional techniques (closed tray [CT], non-hexed open tray [NHOT], and hexed open tray [HOT]) and one digital technique (intraoral scanning [IOS]). A total of 160 impressions were made. The reference and experimental scan data were superimposed by using the best-fit alignment algorithm. Angular (AD), linear (LD), and 3D (RMS) deviations were computed, and obtained data were statistically analyzed. Results: In premolar implant sites, AD and LD values were significantly affected by model type (P ≤ .001 for AD and LD) and impression technique (P = .001 for AD, P = .002 for LD). However, no significant interaction was detected (P = .703 for AD, P = .768 for LD). Model 1 (0.44 ± 0.25 for AD, 7.79 ± 6.29 for LD) and the NHOT technique (0.49 ± 0.43 for AD, 9.04 ± 8.14 for LD) exhibited the lowest mean AD and LD values. In molar implant sites, AD and LD values were significantly affected by model type (P ≤ .001 for AD and LD) and impression technique (P ≤ .001 for AD and LD), as well as by their interaction terms (P = .037 for AD, P = .005 for LD). Considering interaction terms, while the highest and lowest mean AD values were exhibited by IOS-model 4 (1.56 ± 0.25) and NHOT-model 2 (0.46 ± 0.28), respectively, the highest and lowest mean LD values were exhibited by CT-model 4 (41.40 ± 14.48) and NHOT-model 2 (8.03 ± 4.86), respectively. RMS estimate values were significantly influenced by model type (P ≤ .001) and impression technique (P ≤ .001), as well as by their interaction terms (P = .019). The highest and lowest mean RMS values were exhibited by IOS-model 4 (70.02 ± 4.74) and NHOT-model 2 (25.96 ± 17.67), respectively. Conclusion: In the case of angulated and deeply placed implants, splinted NHOT and HOT techniques can be recommended for better trueness. [ABSTRACT FROM AUTHOR]

Owing to the need for beauty in modern society, cosmetics are essential to enhance femininity and attractiveness. Lipstick is effective in reinforcing femininity and increasing beauty. This study conducted a psychophysical experiment to investigate the association between lipstick colors and the impressions they create. Thirty‐five observers were invited to participate in the experiment. They were asked to assess 20 lipstick colors on 23 impression scales. The results showed that the impressions created by the lipstick colors comprised three factors: charm, cuteness, and contemporary. Charm was correlated with a* and lightness value of lipstick color and the color difference between lipstick‐skin colors. Cuteness was negatively correlated with the hue angle of the lipstick colors and lightness differences between lipstick‐skin colors. Contemporary was correlated with chroma differences and negatively correlated with b* of lipstick color. These lipstick colors can be classified into three groups based on impression factors. The results showed that a* value of lipstick color and the color difference (△E) between lipstick and skin color are identified to determine the grouping of lipstick colors. [ABSTRACT FROM AUTHOR]

Preliminary impressions must record the periphery and height of maxillary defects to allow for an eventual extension of the master impression tray. These impressions are usually made with irreversible hydrocolloid. Carrying the impression material into the defect can be complex, especially in the case of a limited oral opening. Moreover, the patient can be harmed during the removal procedure, and material may be stuck in anatomical structures. The technique presented in this article avoids these issues in any maxillary defect with a two‐step preliminary impression. An elastomeric material ball is first placed in the defect until full setting. Then, this "obturator bulb" is removed and eventually relined until it is retentive. Retentions are designed on the oral side of the bulb and the bulb is placed back into the defect. Finally, an alginate over‐impression of the maxillary is made. The alginate is removed after full setting, and the obturator can be reassembled on the maxillary impression to provide a full recording of the maxillary. This protocol can safely be used for defects of any size, despite eventual limitations in oral opening. [ABSTRACT FROM AUTHOR]

Status-related impressions influence important interpersonal dynamics, including moral judgments of good or bad, and right or wrong, whereas these impressions can be formed based on subtle cues (e.g., formal versus casual attire of transgressors). The current research examined how attire influences moral judgments in transgressive contexts and for different transgressions. We proposed that attire would have different effects on moral judgments depending on whether transgressions were accompanied with contradictory moral claims (i.e., hypocrisy versus non-hypocrisy), and attire and hypocrisy would influence moral judgments through perceived intentionality (i.e., whether transgressions were committed intentionally or accidentally). We tested these hypotheses in four studies (total N = 1,007; including two pre-registered), by examining both people's moral blame of transgressive behaviors and their moral impressions (e.g., trustworthiness and compassion) of the transgressors. Findings were largely in line with hypotheses: People favored formal- over casual-attire targets when both transgressed in non-hypocritical contexts and with ambiguous intentionality (Studies 1 to 3). However, moral favoritism based on formal attire was diminished when transgressions were hypocritical and perceived as intentional (Studies 2 to 4). For various contexts where people (need to) make moral judgments, our findings suggest that cues of high status are key ingredients to moral evaluations, but signs of hypocrisy and intentionality may seriously undermine the workings of these cues.

People largely preserve spontaneously drawn trait inferences from others' behaviors in their memory, even when contrary information is present. However, we suggest that updating could be manifested in future predictions about others. Experiment 1 replicated previous work, showing no updating in the memory of initially inferred traits upon learning trait-inconsistent new information. Experiments 2–4 tested whether people's reliance on the initially implied traits in their future predictions changed as an indicator of updating. Participants aligned their predictions with the initially implied traits when the new information was neutral. However, after learning trait-inconsistent (vs. neutral) new information, they made weaker future predictions consistent with the initially implied traits and stronger predictions consistent with alternative (inconsistent) traits, revealing updating. The patterns were similar across continuous and categorical prediction measures (Experiment 3) and generalized to other valence-matching impressions (Experiment 4). The present work reveals nuances that extend our understanding of impression updating and suggests a utility in combining memory measures of impression formation with behavior predictions.

The correct impression in complete or partial prosthodontics is an essential stage in the manufacturing of functional dentures. Through an impression, all the necessary information is sent form the dental office to the dental laboratory, for creating the individual impression tray, with the help of which a much more accurate impression can be obtained comparing to a standard impression tray. Using the functional impression made with the help of the individual impression tray, the functional model is obtained, on which the occlusal registration rims and later on the trial denture will be made.

As a reflection of social patterns, culture is bound to change and the representations from the past distorted in the present need to be decoded to remove the staleness and fixation on various notions passed as absolute truths. This dichotomy inspires an investigation into an iconic representation of womanhood from the stature of an episode from mythological epic Mahabharata and the paintings of Shakuntala by the painter Prince Ravi Varma of erstwhile Travancore in the state of Kerala in colonial India to unravel the stories that characterized popular imagination of women in history. The theoretical framework of aesthetics in the depiction of human forms that define perceptions of gender directs this study to avail a close reading to evaluate the growth of empowerment of women within the dialectics of history and culture. 'Ekphrasis' studies mainly how visual arts are represented in literature and here interestingly visual art becomes the ekphrasis of the written text. A proposal of the theory of 'elimination', the study intends to debunk the societal gaze of the feminine form as fragile hindering the strength of character by analyzing the hidden details in art. The relevance becomes manifold in the twenty-first century as the new generation is ardently trying to break stereotypes. The limitations of binary ideas of masculine and feminine are interwoven mainly with physical characteristics. The pressure to mimic these attributes leads to the exclusion of anything beyond that idea which disturbs the balance of gender equality and justice. [ABSTRACT FROM AUTHOR]

To clarify comfortable bedding colors, we examined 80 psychiatric inpatients' impressions of bedding in 6 different tones (pale, dull, bright, greyish, deep, and light) of blue, focusing on the suitability for patient rooms. 1) In both the male and female groups, the samples chosen as the most and least suitable for patient rooms were pale tone and greyish tone, respectively. 2) The female group rated pale tone and light tone more positively than the male group. 3) Through factor analysis, 2 factors were identified: [psychological comfort] and [brightness/warmth]. For Factor 1, greyish tone was rated significantly lower than pale and light tones only in the female group. For Factor 2, greyish tone was rated significantly lower than pale and light tones in both the male and female groups. Based on these findings, bedding in various tones of blue, except for greyish tone, is recommendable for psychiatric wards. [ABSTRACT FROM AUTHOR]

Our research aims to investigate the impact mechanism of brand loyalty among gamers during the gaming process within the framework of brand loyalty theory and cognitive theory. We surveyed game players from Zhejiang Province, China. The research methods include a questionnaire survey and structural equation modelling. Results show that game experience, interaction, and impression are positively correlated with game trust, while game trust is positively correlated with game brand loyalty. Game trust, as a mediator variable, plays a complete mediation role. The clustering results of player gender and age as moderating effects are not significant. Based on the analysis results, we have suggested corresponding policy recommendations and reflections. Our research contributes to the analysation of impact mechanism of brand loyalty during the gaming process through the establishment of a structural equation model and provides suggestions and reflections on the development of the gaming industry.

Abstract Purpose This systematic review aimed to investigate the accuracy of intraoral scan (IOS) impressions of implant-supported restorations in in vivo studies. Methods A systematic electronic search and review of studies on the accuracy of IOS implant impressions were conducted to analyze the peer-reviewed literature published between 1989 and August 2023. The bias analysis was performed by two reviewers. Data on the study characteristics, accuracy outcomes, and related variables were extracted. A meta-analysis of randomized control trials was performed to investigate the impact of IOS on peri-implant crestal bone loss and the time involved in the impression procedure. Results Ten in vivo studies were included in this systematic review for final analysis. Six studies investigated the trueness of IOS impressions, but did not reach the same conclusions. One study assessed the precision of IOS impressions for a single implant. Four clinical studies examined the accuracy of IOS implant impressions with a follow-up of 1–2 years. In full arches, IOS impression procedure needed significantly less time than conventional one (mean difference for procedure time was 8.59 min [6.78, 10.40 min], P

Purpose: The purpose of the article is to present the author’s own comprehensive method of testing impression management in narrative reporting and the possibility of using it to evaluate and measure impression management and identify the strategy of impression management in letters to shareholders. Methodology/approach: The development of the method of testing impression management in narrative reporting was preceded by a critical analysis of the literature. Content analysis and the IMNR (impression management in narrative reporting) index were used in the empirical study. The study covered ten letters to shareholders of Polish companies. Findings: The article presents a tool for assessing and measuring impression management, showing how it is calculated. It also presents the results of a survey, showing the possibilities of using the IMNR index. In the audited board of directors’ letters, the occurrence of all analysed impression management strategies was identified. The article discusses selected methods of impression management observed in those documents. Research limitations/implications: The proposed IMNR index is limited to selected impression management strategies and the means by which they can be detected. As the study was limited to selected companies, future research may investigate other entities or reporting forms. Additionally, only documents written in Polish were analysed. Originality/value: The article presents the original IMNR index, which makes it possible to comprehensively examine impression management and compare reports. The conducted empirical study covered a wide range of ways of managing impressions. Documents written in Polish were examined. As Polish researchers have been dealing with the issue of impression management by Polish companies since only relatively recently, the research gap, which this article partially fills, is extremely wide.

Background. The study of psychological mechanisms and patterns of "conscious" regulation of psychic states turns us to the structures of consciousness and their functions in the regulatory process. These structures and mechanisms remain the least studied to date, while the need to understand the psychological mechanisms of self-regulation of states is extremely relevant, and knowledge about them is in demand in various situations of a subject’s life. Objective. The presented analytical article analyzes the concept of "situation" (approaches, principles, structure, levels, etc.) considered as a "psychological situation" and investigates its role in the actualization of the mental regulation of psychic states. Results. It is shown that psychological situation, through the formation of an impression, which is a cognitive-affective complex, “launches” the regulatory process, actualizing the structures of consciousness constituted by semantic, reflective, representative structures, experiences, and the Self system. The article provides an analysis of results of the situational conditioning of self-regulation of states among the employees of government institutions, in the process of teaching students, in difficult life situations (reversible and irreversible) as well as its impact on the activation of consciousness structures and, accordingly, on the operational means of regulation. Consideration is also given to the relationships between mental structures in the process of regulating the subject's states. Conclusion. The formation of functional structures "situation - mental structures - regulatory means - mental states" occurs in the process of psychic states regulation. The actualization of functional structures is due to the purpose of regulation - the need to change the state in accordance with requirements of the situation of the subject's life activity. Activation of the consciousness structures mediating the choice of operational means of regulation and their use leads to a change in the psychic state.

The review of the works and the writings of philosophers regarding the origin of philosophical concepts and the origin of the concepts and imaginations before it are indicative of the gradual and influenced formation and importance of this issue from a series of ideas in both the west and Islam. In the western world, the idea of innate ideas raised by rationalists and the rejection of the same idea by empiricists finally leads the Scottish philosopher Hume, who is evasive from the mysterious philosophy,to tract the origin of concepts and adaptations and by presenting a plan to refer concepts and adaptations has beaten all philosophies and introduced them as illusory and invalid concepts,and appeals to justifying the existence of these concepts in the mind to psychological and imaginary bases. later and in the passing of time due to the entry of western ideas into Iran,especially in the contemporary era,the issue of the origin of concepts and ideas (in general) and the origin of philosophical(in particular) by Allamh Tabatabayi has doubled its value and importance. Allameh, like Hume while rejecting the idea of innate and preconceived notions of the mind and bringing science to the field of presence and emphasizing the inherent existence and discovery of science and by reference all concepts and ideas to present science the validity and epistemological value of the philosophical concepts which are in Hume's philosophical dictionary restores what was disappeared and gives new life to philosophy and its concepts.

Objective: This study investigated how the number of images collected for digital measurements in dentistry affects accuracy compared with traditional methods. Methods: A Frasaco maxillary model was scanned using a SHINING 3D AutoScan-DS-MIX dental 3D scanner to create an STL file. The maxilla was molded 10 times using polyvinyl siloxane (Zhermack Elite HD+) to produce plaster models, which were scanned with the same reference scanner to generate 10 STL files. The Frasaco model was scanned 10 times, capturing images in intervals of 800–1000, 1000–1200, and 1200–1500 using a 3Shape TRIOS 3 intraoral scanner, creating additional STL files. These were analyzed with reverse engineering software. Results: The most accurate measurements were obtained using 1200–1500 images. Conventional impression techniques performed significantly worse. There was a significant difference between the groups Digital 1200–1500 and Plaster (p < 0.001) and between Digital 800–1000 and Plaster (p = 0.007). No significant difference was found when the digital groups were compared among themselves. There was also no significant difference between the Plaster and Digital 1000–1200 groups. To compare precision values that were normally distributed across three or more methods, a one-way ANOVA was used. Trueness values that were not normally distributed with three or more methods were compared employing the Kruskal–Wallis test. Conclusions: Different image counts affect digital measurement accuracy. The most accurate measurements were obtained when collecting 1200–1500 images. Conventional impression techniques were shown to perform significantly worse than digital impression.

A coach's nonverbal communication (NC) plays a central role in the construction of the coach–athlete relationship. Moreover, perceived NC and its effect on communication ability and coaching evaluation may differ according to the athletes' demographics. This study explored the impact of perceived NC on coaching evaluation and overall communication among different genders and age groups. The study recruited 233 athletes from five high schools and seven university teams in Japan. The coaches' NC, communication ability, and coaching evaluations were assessed. Negative and positive NC directly influenced coaching evaluation in female athletes. Specifically, negative NC directly impacted coaching evaluation in high school athletes, whereas positive NC directly influenced coaching evaluation in university athletes. Positive NC consistently influenced communication ability regardless of demographics. The findings promote talent development and team management in the coaching context. [ABSTRACT FROM AUTHOR]

People often form immediate expectations about other people, or groups of people, based on visual appearance and characteristics of their voice and speech. These stereotypes, often inaccurate or overgeneralized, may translate to robots that carry human-like qualities. This study aims to explore if nationality-based preconceptions regarding appearance and accents can be found in people's perception of a virtual and a physical social robot. In an online survey with 80 subjects evaluating different first-language-influenced accents of English and nationality-influenced human-like faces for a virtual robot, we find that accents, in particular, lead to preconceptions on perceived competence and likeability that correspond to previous findings in social science research. In a physical interaction study with 74 participants, we then studied if the perception of competence and likeability is similar after interacting with a robot portraying one of four different nationality representations from the online survey. We find that preconceptions on national stereotypes that appeared in the online survey vanish or are overshadowed by factors related to general interaction quality. We do, however, find some effects of the robot's stereotypical alignment with the subject group, with Swedish subjects (the majority group in this study) rating the Swedish-accented robot as less competent than the international group, but, on the other hand, recalling more facts from the Swedish robot's presentation than the international group does. In an extension in which the physical robot was replaced by a virtual robot interacting in the same scenario online, we further found the same results that preconceptions are of less importance after actual interactions, hence demonstrating that the differences in the ratings of the robot between the online survey and the interaction is not due to the interaction medium. We hence conclude that attitudes towards stereotypical national representations in HRI have a weak effect, at least for the user group included in this study (primarily educated young students in an international setting).

Purpose: This systematic review aimed to investigate the accuracy of intraoral scan (IOS) impressions of implant-supported restorations in in vivo studies. Methods: A systematic electronic search and review of studies on the accuracy of IOS implant impressions were conducted to analyze the peer-reviewed literature published between 1989 and August 2023. The bias analysis was performed by two reviewers. Data on the study characteristics, accuracy outcomes, and related variables were extracted. A meta-analysis of randomized control trials was performed to investigate the impact of IOS on peri-implant crestal bone loss and the time involved in the impression procedure. Results: Ten in vivo studies were included in this systematic review for final analysis. Six studies investigated the trueness of IOS impressions, but did not reach the same conclusions. One study assessed the precision of IOS impressions for a single implant. Four clinical studies examined the accuracy of IOS implant impressions with a follow-up of 1–2 years. In full arches, IOS impression procedure needed significantly less time than conventional one (mean difference for procedure time was 8.59 min [6.78, 10.40 min], P < 0.001), prosthetic survival rate was 100%, and marginal bone levels of all participants could be stably maintained (mean difference in marginal bone loss at 12 months was 0.03 mm [-0.08, 0.14 mm], P = 0.55). Conclusions: The accuracy of IOS impressions of implant-supported restorations varied greatly depending on the scanning strategy. The trueness and precision of IOS in the partial and complete arches remain unclear and require further assessment. Based on follow-up clinical studies, IOS impressions were accurate in clinical practice. However, these results should be interpreted with caution, as some evidences are obtained from the same research group. [ABSTRACT FROM AUTHOR]

Featured Application: An alginate-based impression material with bacteriostatic properties for application in the production of dental prosthetics, requiring a less labour-intensive process of disinfection. Disinfection of alginate impressions used in dental prosthetics is a very problematic procedure, during which the dimensions of the obtained model can change, and it can be easily mechanically damaged. Therefore, it would be beneficial to create a material with bacteriostatic properties for this application. In this work, we investigated alginate materials with the addition of 0.25–1.0 wt% of zirconium phosphate-based ion exchange resin containing silver and compared them with commercial alginate impression products. The obtained materials passed the normative requirements of ISO 21563:2021 (setting time, elastic recovery, strain in compression, compatibility with gypsum, detail reproduction, tearing strength, and linear dimensional change) as well as bacteriostatic properties in relation to Streptococcus mutans. The newly developed alginate materials met all the properties required by the standards. Their setting time was comparable to the commercial materials, and their 24 h contraction did not exceed 1.3%. Furthermore, the tearing strength was 0.42–0.48 MPa, less than that of the comparative commercial materials (0.52–0.56 MPa). From the point of view of clinical practice, it will be possible to create an alginate material with bacteriostatic properties that will prevent the transmission of cross-infections.

In today's environment, where consumers have a wide range of information available to them, it is important for companies to use more effective and flexible approaches to the market. Modern information technology helps the marketer to be closer to the buyer than in the past and to understand the customer's needs and desires well. In addition, marketers need to have a good understanding of the capabilities and benefits of different marketing communication tools and media channels. In today's competitive environment, it is becoming increasingly important for companies to use incentives that are better suited to today's targeted strategies. Effective marketing communications play an important role in a company's success in the marketplace. It is important in creating an impression of the company and its brands. Events help companies to achieve this goal. The purpose of this paper is to summarise and present the main benefits that companies can achieve through the intelligent use of events. Events are used by many companies to impress other people. And companies can gain their favour by making a great impression on the public. Thus, event marketing influences consumer attitudes towards different brands, consumer behaviour and stimulates purchases. An important question is when and how special events will be implemented. Their proper planning, organisation and execution will bring the company high recognition and economic benefits. Methodology. Secondary data was used in the course of writing this article. Modern scientific works of scientists and researchers were studied, and information was searched for using Internet sources. The paper examines modern forms of event marketing, individual approaches to work in this area and aspects of its development. Research results. Based on various reliable sources of information, a clear picture of the current situation in Georgia in this area was created. It has been found that companies do not use measures with the frequency that would bring them high results. They use only certain approaches. The paper examines the conceptual aspects of event marketing, analyses the definitions and opinions of various scientists and specialists in this area. Practical implications. The article discusses the risks and problems associated with the implementation of events, and presents a number of conclusions and recommendations to improve the efficiency of the use of events.

The materials utilized in various domains of prosthodontics have changed overtime. In recent years, patients have been requesting a metal-free, lightweight, and tooth-colored prosthesis. In dentistry, metal and other ceramics are used in a variety of treatment methods. Polyetheretherketone (PEEK) can be employed in a variety of ways in prosthodontics. PEEK is being investigated as an alternative to metal and glass ceramics due to their acceptable fracture resistance, shock-absorbing capabilities, and improved stress distribution. Due to its favorable mechanical and chemical properties, PEEK is recognized as a high-performance polymer in engineering and medical applications. In dentistry, a material must have excellent biocompatibility, strong mechanical qualities, be resistant to high temperatures, have a low moisture absorption and elasticity modulus, be flexible, and have a high chemical wear resistance. PEEK material possesses all of these characteristics, making it ideal for use in dentistry. Using PEEK with computer-aided design and computer-aided manufacturing fabrication (CAD/CAM) will allow us to save natural teeth in tough situations. The technique allows the patient to have upgrades that are physiologically and technically superior in processing and improve their appearance. Dental rehabilitation with complete satisfaction is in doubt, mostly because of the imperfect adaptation of the crown. Hence, the restoration of teeth using PEEK with CAD/CAM technology as an alternative to glass or metal ceramics provides an excellent opportunity for better esthetic restoration and patient satisfaction. In this present case presentation, we highlighted two clinical cases showing teeth in the upper left arch and two teeth in the lower right region of the jaw using CAD/CAM-fabricated PEEK post, core, and PEEK crown, which were briefly demonstrated.

Purpose: To compare the marginal accuracy of zirconia crowns fabricated by different workflows (conventional and digital) and designs (monolithic and veneered). Materials and Methods: A prepared maxillary first molar was used for the study. Four workflow combinations were evaluated: (1) intraoral scanning and monolithic zirconia (IOS‐M), (2) intraoral scanning and veneered zirconia (IOS‐V), (3) conventional impression and monolithic zirconia (IMP‐M), and (4) conventional impression and veneered zirconia (IMP‐V). All of the specimens had similar designs. The veneered groups had a buccal cutback for esthetic veneer application. A total of 10 crowns were produced in each workflow. The vertical and horizontal marginal accuracies were measured with a traveling microscope. Depending on the normality of the data, one‐way analysis of variance test or Kruskal‐Wallis test were applied to evaluate the differences among the groups (α = 0.05). Results: The most superior vertical marginal accuracy was observed for IOS‐V (mean = 22.5 μm; SD = 6.7 μm), followed by IMP‐V (mean = 23.9 μm; SD = 7.8 μm), IOS‐M (mean = 28.7 μm; SD = 10.3 μm), and IMP‐M (mean = 39.8 μm; SD = 22.0 μm), respectively (p < 0.001). The IOS‐M had the greatest mean horizontal discrepancies (mean = 23.9 μm; SD = 4.3 μm) followed by IMP‐M (mean = 21.3 μm; SD = 5.7 μm), IMP‐V (mean = 19.2 μm; SD = 5.3 μm) and IOS‐V (mean = 17.6 μm; SD = 5.7 μm) (p < 0.001). Conclusions: Monolithic zirconia crowns fabricated digitally had superior marginal accuracy than monolithic zirconia crowns fabricated conventionally. Esthetic buccal veneering of predominantly monolithic zirconia copings improved the vertical and horizontal marginal accuracies. [ABSTRACT FROM AUTHOR]

Humans exhibit colour vision variations due to genetic polymorphisms, with trichromacy being the most common, while some people are classified as dichromats. Whether genetic differences in colour vision affect the way of viewing complex images remains unknown. Here, we investigated how people with different colour vision focused their gaze on aesthetic paintings by eye-tracking while freely viewing digital rendering of paintings and assessed individual impressions through a decomposition analysis of adjective ratings for the images. Gaze-concentrated areas among trichromats were more highly correlated than those among dichromats. However, compared with the brief dichromatic experience with the simulated images, there was little effect of innate colour vision differences on impressions. These results indicate that chromatic information is instructive as a cue for guiding attention, whereas the impression of each person is generated according to their own sensory experience and normalized through one's own colour space.
