This paper presents and tests a conceptual model of Technology Acceptance Model(TAM) that explains perceived usefulness, perceived ease of use, organizational commitment and turnover intention in terms of psychological commitment in mandatory environments. The model focuses on psychological commitment(Kelman's internalization, identification, compliance) as the primal of predictor of perceived usefulness, perceived ease of use and organizational commitment we discuss our current understanding of technology acceptance, as well as the notion of mandated use. The results and implications of the research are as follows. First, organizational commitment negatively influence turnover intention in mandatory environment. Second, perceived usefulness positively influence organizational commitment in mandatory environments. Third, psychological commitment positively influence organizational commitment, perceived usefulness and perceived ease of use in mandatory environments. Fourth, perceived ease of use positively influence perceived usefulness in mandatory environments. Through this research, psychological commitment is a strong determinant of technology acceptance in mandatory environments. These findings advance theory and contribution to the foundation for future research aimed at improving our understanding of user adoption behavior in mandatory environments.

The relationship among food behavior, psychological factor(life strees) and perceive tiredness was investigated in 514 adolescents. Tiredness was measured in four cases: in lessons, before school, in the early evening and at weekends. Adolescents felt most tired in lessons and before school, and leat at weekends. Irregularity of meal times and skipping breakfast were positively correlated with tiredness in lessons and befor school. Consumption of some foods was related to perceived tiredness. High sugar or fat containing ice-cream, hamburger of fizzy drinks in boys, and crisps and cookies in girls were positively associated with tiredness. Whereas beans and mushrooms were negatively associated with tiredness in girls. Life stress(by scholastic problem and personal problem) of adolescents was positively related to tiredness. The contribution of stress to tiredness was much greater than of food behavior according to multiple linear regression .There was no relationship between nutrients intake and tiredness in lessons and before school which were more strongly influenced by stress, whereas the relationship was found at weekend without influences of stress. The more tired, the lower NARs(nutrient adequacy ratio) of energy, phosphorus, vitamin A, vitamin B$_2$, and niacin were. In conclusion, some eating behavior and psychological factor can cause tiredness in adolescents, but tiredness in school and before school had more of a psychological cause than at weekend.

The main purpose of this research is to understand the strongest predictors of wearable adoption among athletes with an emphasis on the perceived ethics of biometric data. We performed a word co-occurrence study of biometrics research to determine the ethical constructs of biometric data. A questionnaire incorporating the Unified Theory of Acceptance and Use of Technology (UTAUT), Health Belief Model and Biometric Data Ethics was then designed to develop a neural network model to predict the adoption of wearable sensors among athletes. Our model shows that wearable adoption's strongest predictors are perceived ethics, perceived profit, and perceived threat; which can be categorized as professional stressors. The key theoretical contribution of this paper is to extend the literature on UTAUT by developing a predictive modeling of factors affecting acceptance of wearables by athletes, and highlighting the ethical implications of athlete's adoption of wearables.

This study is aimed to investigate the factors predicting the responses after volunteering activities among corporate volunteers. While positive responses to volunteering are conceptualized as both the degree of satisfaction from volunteering and the perceived contribution of volunteering, negative responses are conceptualized as the degree of burnout. Family supports, the volunteering support system of corporation, various human relations in volunteering sites are selected and empirically tested as variables predicting the differential responses after volunteer activities. Questionnaire data were collected from 250 corporate volunteers and analyzed through hierarchical regression analysis. The results showed that while family supports have no significant effects on volunteering responses, corporate support system of volunteering have significant effects. Additionally, human relations with clients and volunteers managers have strong and positive significant effects on positive responses including the degree of satisfaction and the perceived contribution. However, no significant effect has been found on negative responses represented by burnout. Findings from this study emphasized the importance of human relations management in volunteering sites for corporate and nonprofit volunteer managers to increase the positive response from corporate volunteers.

This study reinterpreted the value of traditional communities in rural areas and explored ways to revitalize sustainable communities. To do this, we surveyed the members' perceptions about the activities of the community organization as assessed through a questionnaire. The questionnaire items focused on the participation, satisfaction and contribution of the members of the community organization, with additional questions investigating the idea of the community vitalizations plan. A self-report questionnaire survey was administered to 321 members of the community, and the results were analyzed through technical data, t-test and ANOVA analysis by using the SPSS program. In the results, the perceptions of the members of the traditional village community differed significantly according to socio - demographic factors and member recognition characteristics. Especially, males were more voluntarily and positively compared to females, and the lower the age of satisfaction, the lower was the perceived individual satisfaction with community activities. In the case of perceived contributions to individuals and the community, the participants perceived positively in the emotional support for the individual's participation in the organization. On the other hand, the results confirmed that the contribution to the local community is important in realistic aspects such as regional vitalizations. It is confirmed by the decrease in the number of members in response to the difficulty of the organization. (Ed- 'the lack of the size of the membership' simply repeats 'the decrease in the number of members'; thus it's unnecessary).

The study is investigated socioeconomic variations in perceived oral health status and contribution of oral health behavioral factors. A nationally representative sample (365 health and 1,787 unhealth aged 20 over years) from the 2015 Korea National Health and Nutrition Surveys was analyzed using logistic regression. Perceived oral health was lower among lower socioeconomic groups compared with higher socioeconomic groups. This association was increased when demo-socioeconomic factors and oral health behavioral were adjusted. When each oral health behavioral factor was considered separately, mediators such as smoking, frequency of tooth brushing and used oral care products or oral health examination explained a large part of the increased socioeconomic oral health status. Subjective bad oral health arise from different socioeconomic status, but this difference is increased by oral health behavioral factors. Therefore, socioeconomic inequity in perceived oral health status can be corrected more effectively by promotional oral health behaviors.

Congenital heart disease is now estimated to be the most prevalent chronic illness in children. The overall purpose of study is to enhance our understanding of mother's perception of family stress, perceived social support, and coping who has a child newly diagnosed with congenital heart disease. In this investigation, the relationship between family stress, perceived social support, and coping within the context of a acute, non life- threatening chronic illness in the situation of newly diagnosed as Rolland's typology of chronic illness. The study employed data from a subset of a large longitudinal study, children's chronic illness: parents and family adaptation conducted by M. McCubbin (5 R29 NR02563) which was funded by the NIH. The subject for this study were 92 mothers who have a child under age 12 who was newly diagnosed with congenital heart disease within the last 3-4 months. Results form correlational and regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping of mothers. Child and family characteristics appeared to be important predictors of perceived social support and mother's coping. Therefore, the findings provide an incremental contribution to the explanation of effects for perceived social support and may challenge resiliency model in previous literature. Further, these findings suggest that perceived social support and coping are both influencing in the resiliency of relatively high risk groups of families who has a child with congenital heart disease.

Purpose - Due to the Covic-19 pandemic, the perceived value of video conferencing platforms has been increased drastically. However, there is little guidance on how service providers can improve video conferencing platforms. The purpose of this study is to investigate the factors that influence the users' perceived value of video conferencing services based on the heuristic-systematic model and the value-based adoption model. Design/Methodology/Approach - In this paper, we theoretically explore the relationship of the antecedents of perceived value(credibility, expertise, attractiveness, economic feasibility, security, and interactivity) and its outcomes (perceived usefulness, perceived risk and perceived value). The outcomes of this research is a conceptualization of antecedents of perceived value supported by research hypothesis based on the existing literature. A total of 100 valid questionnaires were collected to empirically test the research model. Findings - The analysis results showed that credibility, economic feasibility, and interactivity positively influenced perceived usefulness. On the other hand, credibility, professionalism and interactivity negatively influenced perceived risk. Perceived usefulness positively affects perceived value and perceived risk has a negative effect on perceived value. The brand image as a moderating variable was found to decrease the effect of perceived risk on perceived value. Research Implications - The contribution of this study is significant for video conferencing providers as follows. First, a service provider can actively utilize influencers or referees with high credibility and expertise to maximize the perceived usefulness of users. Second, economic feasibility should be ensured in respect of users through various alliance discount strategies. Third, a video conferencing service company needs to build a positive brand image in order to increase users' perceived value.
