Purpose The study examines the impact of the level of anthropomorphism (both in appearance and behavior) of virtual humans on user liking. It investigates whether this relationship is mediated by social comparison experiences, with the moderated mediation effect of users' desire for self-improvement. Design/methodology/approach A between-groups experimental design was employed to examine the impact of different levels of appearance(low/mid/high) and behavior(low/high) anthropomorphism on user liking of virtual humans. The experiment was conducted in an online environment, and participants were randomly exposed to one of six stimuli, which were Instagram-like posts. Findings The results indicate that as virtual humans become more anthropomorphic, they have a positive impact on user liking. However, once the level of anthropomorphism in appearance reaches a certain point (mid vs high), there is no significant difference in user liking. Users who perceive virtual humans as highly anthropomorphic tend to engage in more social comparison experiences, which positively affects their liking for these virtual humans. Conversely, individuals with a high desire for self-improvement found that the positive effect of appearance anthropomorphism on liking through social comparison experiences was reduced. The study extends the application of social comparison theory by examining its impact on influencer marketing with virtual beings. It provides valuable insights for the formulation of influencer marketing strategies using virtual humans.

The premise for the study reflected in this article is the need to dispose of industrial waste, which is increasingly being used in the construction materials industry. Also, dynamically developing building industry demands attention of scientists and a direction of their works on improvement of the technology of carrying out construction works. Thus, the article is devoted to studying the influence of various chemical additives and fine fillers (industrial wastes) available in Kazakhstan on self-compacting concrete (SCC) mixtures and its rheological, physical, and technical properties. According to the studies, revealed the most efficient type of fine-dispersed filler and the most optimal type of chemical additive to enable obtaining a high-quality SCC mixture based on local raw materials. As a result, the use of microsilica in comparison with other industrial wastes resulted in a conglomerate with high compressive strength of SCC at early terms of curing. In terms of economic efficiency and quality improvement, the results of study are of practical value for the manufacturers of ready-mixed concrete operating in Kazakhstan.

Clustering is a method for unsupervised learning. General clustering tools have been depended on statistical methods and machine learning algorithms. One of the popular clustering algorithms based on machine learning is the self organizing map(SOM). SOM is a neural networks model for clustering. SOM and extended SOM have been used in diverse classification and clustering fields such as data mining. But, SOM has had a problem determining optimal number of clusters. In this paper, we propose an improvement of SOM using gap statistic and probability distribution. The gap statistic was introduced to estimate the number of clusters in a dataset. We use gap statistic for settling the problem of SOM. Also, in our research, weights of feature nodes are updated by probability distribution. After complete updating according to prior and posterior distributions, the weights of SOM have probability distributions for optima clustering. To verify improved performance of our work, we make experiments compared with other learning algorithms using simulation data sets.

Objectives: The purpose of the study was to investigate the correlation between self-esteem, self-efficacy, and awareness for disability in dental hygiene students. Methods: A self-reported questionnaire was completed by 521 dental hygiene students from 5 universities in Gwangju and Jeonnam frm June 13 to July 16, 2016. The questionnaire consisted of self-esteem by Rosenberg (10 items), self-efficacy by Schwarzer (7 items), and the negative awareness for disabled person by Siller (24 items) using Likert 5 point scale. Results: Those who did volunteer activity for disabled person showed high self-esteem and self-efficacy than those who did not. Students having disability-related training experience had high self-esteem (p<0.05). Higher the self-esteem was, higher the self-efficacy was (r=0.655). Higher the self-efficacy was, the lower the negative awareness was (r=-0.142). Higher self-esteem enhanced the positive awareness for the disabled person (r=-0.206)(p<0.01). Conclusions: The systematic curriculum development for the disabled person recognition improvement should be made in order to enhance self-esteem and self-efficacy of the dental hygiene students.

This study aims to provide useful basic materials for planning the Health Improvement Program and Policy for men aged 20 40. This study investigated 889 subjects, and at each corresponding age, who were collected among the trainers at the Civil Defense Training Institute in K-ku, Incheon City. The data collection period lasted from April to July of 2003. I revised and complemented the measurement tool for the Health Improvement Life Style developed by Jung Eun-Kyung. For analysis of the acquired data. I used SPSS11.0 program. The study shows that the Health Improvement Action of a group of middle aged men averaged 2.80, and 0.44 point out of 5. According to the results found during the analysis of the generic characters of differences in behaviors of Health Improvement. It was revealed that there were significant differences in age, regular exercise and health interest, stress management, self-concept as well as degrees of interest in health, and education level. According to monthly income levels, regular exercise and degrees of self-concept degrees were significantly different from each other. According to marital status. balanced diet and regular exercise were related to each other. According to religion, balanced diet, stress management degree, self concept degree, and degrees of interest in health, significant differences were shown. Based on the earlier mentioned results, we should pay attention to act more, rather than merely recognize the development of the health improvement program of our regional community. Also, it is necessary to find out the cause, which lowers men's interest in health.
