In this study, we would like to consider the main factors that influence psychological well-being by using social network service. suggest ways to use healthy social network services, and empirically verify how behavioral approaches, in other words self-determination theory, that deals with human psychological needs, affect psychological well-being by self-esteem and satisfaction to comprehensively examine the characteristics of service and user individuals and social influences, etc. First research result, it has been confirmed that the autonomy has a positive effect on self-esteem. Second, it has been confirmed that the autonomy does not have a positive effect on satisfaction. Third, it has been confirmed that the competence has a positive effect on self-esteem. Fourth, it has been confirmed that the competence does not have a positive effect on satisfaction. Fifth, it has been confirmed that the relationship has a positive effect on self-esteem. Sixth, it has been confirmed that the relationship does not have a positive effect on satisfaction. Seventh, it has been confirmed that self-esteem has a positive effect on psychological well-being. Eighth, it has been confirmed that self-esteem has a positive effect on satisfaction. Ninth, it has been confirmed that satisfaction has a positive effect on psychological well-being. These results mean that meeting basic human psychological needs has a significant impact on psychological well-being of the social network service users. In addition, it was confirmed that increasing the desire for autonomy, competence, relationship, which are factors of self-determination, is an important factor to enhance psychological well-being.

This study was based on the 'Escape Theory' model suggested by Baumeister(1990). Based on this analysis framework, this study attempted to examine that complicated direct and indirect effect of school risk factors(risk of academic scores, risk of relation with teacher and risk of peer relation) on suicide ideation in adolescence, through negative self-esteem, depression and withdrawal coping. To this end, this study used the data from the '2008 Gyeongsangbuk-Do youth crisis survey' conducted by the Youth service center in province of Gyeongsangbuk-Do. The target number of this study was 2,335 students in the age group of middle school and high school. The result of the Analysis indicate that risk of relation with teacher among school risk factors was only one which affected directly and indirectly on suicide ideation. The other side, risk of academic scores and risk of peer relation had indirect effects, via negative self-esteem, depression and withdrawal coping. In conclusion, this study confirmed that school risk factors had effects on suicide ideation directly or indirectly, they were complicatedly connected, through negative self-esteem, depression and withdrawal coping. Therefore, Prevention program for adolescence' suicide ideation or suicide risk require integrated strategies and tactics.

The purpose of this study was to construct and validate a middle - aged exercise adherence model. The model was designed based on self - determination theory. Participants were 215 middle-aged men and women aged 40-60 who had been exercising for more than six months. Data was collected from four big cities of Seoul, Busan, Gwangju and Daejeon in Korea, using a questionnaire consisting of basic psychological needs, intrinsic motivation, social support, and exercise adherence. Data were analyzed with SPSS 19.0 and AMOS 20.0. Social support and exercise adherence of the questionnaire were partially revised and verified by confirmatory factor analysis. The results of the study were as follows. The model's fit indices: GFI = .938, AGFI) = .915, NFI = .912, CFI = .941, and RMSEA = 0.041. The model satisfied the model fit of the structural model equation. This study model based on self - determination theory was confirmed that basic psychological needs, intrinsic motivation, and social support were important factors for the middle - aged's exercise adherence. Basic psychological need and intrinsic motivation had a direct influence on the adherence of exercise, and social support indirectly influenced the exercise adherence through intrinsic motivation. Both basic psychological needs and social support directly affected internal motivation. The most influential factor in the middle - aged's exercise adherence was intrinsic motivation. In conclusion, it was found that intrinsic motivation such as interest and fun is important for the middle - aged to continue the exercise. Also, the basic psychological needs were important for middle aged's exercise adherence. The results of this study will provide basic data for restoring or maintaining health by continuing exercise. Strategies that enhance intrinsic motivation are needed when a chronic ill person needs to continue long-term exercising.

This study aims at developing the measurement tool of reading motivation using self-determination theory (SDT). SDT is not simply divided into the intrinsic and extrinsic motivation. SDT resides along a continuum, with amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, intrinsic motivation. SDT addresses the process of internalization of various extrinsic motives. This study analyzed motivation factor of the measurement tool such as MRQ (motivations for reading questionnaire), MRP (motivation to read profile) ERAS (elementary reading attitude survey, RSCS (reading self-concept scale). The study re-classified analysis results based on SDT. Ultimately, this study was proposed measurement tool of reading motivation using SDT has 6 area, 30 items.

This review paper presents an introduction of contact mechanics and rubber friction theory for sliding friction of elastomer composites in contact with rough surfaces. Particularly, Klüppel & Heinrich theory considers the self-affine (or fractal) characteristic for rough surfaces to predict adhesion and hysteresis frictions of elastomers based on the contact mechanics of Greenwood & Williamson. Due to dynamic excitation process of elastomer composites while sliding in contact with multiscale surface roughness (or asperity), viscoelastic properties in a wide frequency range becomes major contributor to friction behaviors. A brief description and examples are provided to construct a viscoelastic master curve considering nonlinear viscoelasticity of elastomer composites. Finally, application of rubber friction theory to tire tread compounds in traction with road surfaces is discussed with several experimental and theoretical results.

The study attempted to explain the differences among the willingness of companies to accept the self-regulation. The study exemplified the $CO_2$ emissions record labelling program, as a self-regulation program which is considered as a concrete action for corporate social responsibility and substantiality management movement. The study investigated how companies respond to the request from a government to accept the program, which may be potentially contributed to both higher social and financial performance. It is hypothesized that first the company may decide whether the acceptance decision is strategic or non-strategic issues. when considered as non-strategic, the decision will be made on the basis of short term expected returns and costs comparison. It is hypothesized that when considered as strategic, the decision will be strongly influenced by the type of corporate perceptions toward environmental regulations, which has been accumulated by past experiences. Also, the study investigated the good management theory and the slack resources theory which differently predict the direction between social performances and financial performances. The results identified the significant relationships among most variables and supported the slack resources theory. Further, the ethical perception positively influenced the willingness to accept the self-regulation.

The purpose of this study is to find the complementary idea of the psychological elements in aesthetic expression of architectural space in the sense of healing. Marks $L\ddot{u}scher$, the swiss psychologist suggested reasonable categories of emotional character according to the couple combinations among Content, Self-Esteem, Confidence, and Liberty. His theory on healing is not only the concept but the practical method to understand and control the conflict between contrary elements of emotion. Compared to the Freud's objective theory of cause and consequence, his idea is focused on the subjective and autonomous harmony. This theory based on complementary idea is applied to psychological attitude of architects on Spatial Expression in this study. Refuge, Prospect, Flow and Void are assumed as equivalent spatial elements to the four major emotional conditions suggested by $M.L\ddot{u}scher$. The couple combinations among them also characterize the architectural characters definitely and it is expected to be the reasonable criteria in analysing aesthetic value and motive of creating human space.

Mental health experts warn the combination of overwhelming amounts of information, economic instability, political discontent, social injustice, and the high infection and death rates of the ongoing COVID-19 pandemic are negatively impacting mental health in ways that may worsen the pandemic and intensify our primal fear of death. Terror Management Theory (TMT) argues that self-esteem and cultural worldviews serve as defenses against the terror of our own mortality. This theory anchor paper introduces TMT to Library and Information Science (LIS) via a selected literature review on TMT's use in the field of Psychology and an extensive discussion on the conceptual connections to LIS supported with empirical research from related disciplines and contexts. The implications, applications, and usefulness of TMT for LIS research, education, and practice are discussed in relation to the COVID-19 pandemic and other contexts, and a research agenda is proposed.

Private security will be of great importance in the coming 21st century. In the future, most of the crimes will be violent and frequent. In order to prevent crimes private security must be dealt with in public service area and private area. For this reason, nowadays studies on private security is going on actively. But in reality, serious studies on theoretical backgrounds of private security has not been made yet. Currently, almost all of the theories propose various grounds, such as administrative, economic, and social grounds. And they are based on five backgrounds, that is, profit-oriented enterprise theory, economic reduction theory, vacuum theory, interest group theory, and private management theory. The article furnishes several grounds in addition to these. They are local self-government, management of local self-government, and task-force of guard enterprise. In this article, I am going to present some perspectives in classifying the theories. They are administrative, economic, and social perspective. They are shown as follows by figure. In conclusion, based on theoretical backgrounds mentioned above, private security will be advanced constantly in the future. But in carrying out studies on private security, approaching method of proposing the developmental model is more important than theoretical approaching method.

Human resource theories of becoming entrepreneurs or self-employed rather than finding employment are compared as applied to fit the occupational data of technological entrepreneurs and technology jobs. The human capital theory posits that technological entrepreneurs are prepared to become a jack-of-all-trades with a variety of fields of education. Hobo theory of entrepreneurship assumes that entrepreneurs have strong taste against concentrating on a few activities, which tend to drive entrepreneurs away from employed jobs depressing their expected income. Another theory assumes that entrepreneurs have some unobserved productive qualities and abilities over employed people. Immigrant entrepreneurs could presumably be pressured out of employment under racial discrimination. Since technology jobs are mostly filled by those educated in the science and technology fields, and they presumably offer great reward to professional concentration, technological entrepreneurs may not benefit from becoming jacks-of-all-trades compared to finding employment in technological jobs income-wise. Asian immigrants in the 2000 US Census data are compared to white immigrants in technological jobs to test alternative human resource theories of entrepreneurship. Using English language ability as a proxy for the variety of education, I find in the white immigrant technological entrepreneurs support for the jack-of-all-trades theory, while in the Asian immigrant technological entrepreneurs hobo theory is supported. In the Asian technological workers only there appears the significant self-selection or comparative advantage component, while at the same time discriminatory components are significant.
