Purpose: This study was conducted to investigate the relationship between self-esteem and coping skills among middle school students. Method: The participants were 674 students in three middle schools in GyeongGi-Do. The data were collected from June 10 to 20, 2005. The instruments used were the Rosenberg Self-esteem Scale and the Ways of Coping Checklist. The data were analyzed using the SPSS-Win 12.0 program. Result: Self-esteem showed a significant positive correlation with positive coping skills (r= .162. p= .000). As for the positive coping skills, there was a significant difference by grade (F= 4.69, p= .010), relationship with parent (F=4.036, p= .02), and relationship with siblings (F=3.902, p= .02). As for the negative coping skills, there was a significant difference by grade (F=3.05, p= .04), condition of living with parents (F=3.559, p= .02), economic status (F=3.736, p= .02), relationship with sibling (F=3.408, p= .03), and troubling matters (F=5.422, p= .005). Conclusion: Positive coping skills may be effective for adjustment because they positively related to self-esteem. Self-esteem and coping skills should be considered when an adolescent's mental health enhancement program is designed.

Purpose Recently, with the enhancement of mobile technologies, people have formed various relationships and spreaded networks on social network service(SNS). In addition, although people make a decision based on the thoughts and emotions about self, there is little empirical research on social relations and self-construal of users in social network game (SNG). Design/methodology/approach This study was designed to examine the structural relationships among SNG users' social capital, self-construal, behavioral adaptation, SNG reuse intention and charged item purchasing intention. Findings The results from this study are as follow. First of all, the bonding social capital did not have a significant impact on behavioral adaptation to SNG, but bridging social capital had a positive impact on behavioral adaptation. Second, independent self-construal did not have a significant impact on behavioral adaptation to SNG, but interdependent self-construal had a positive impact on behavioral adaptation. Lastly, the behavioral adaptation to SNG had a positive impact reuse intention and charged item purchasing intention. Also, SNG reuse intention had a positive impact on charged item purchasing intention.

Purpose: The purpose of the study was to investigate the mediating effects of psychosocial well-being on the relationship between self-leadership and learning flow in nursing students. Methods: A total of 148 nursing students with online class experience participated in the study. The data were analyzed using the independent t-test, Pearson's correlation coefficient, PROCESS macro, and bootstrapping methods with SPSS Statistics 26.0. Results: The results showed that self-leadership, learning flow, and psychosocial well-being were significantly correlated, and self-leadership had a direct effect on learning flow. In other words, the higher the level of self-leadership, the higher the learning flow of nursing students. Psychosocial well-being was partially mediated by self-leadership and learning flow. Conclusion: It is necessary to develop and implement programs for self-leadership and psychosocial well-being enhancement as a strategy to enhance nursing students' learning flow.

The purpose of this study was to investigate the differences in optimism, self-esteem and self-leadership according to age, monthly income, and teaching experiences of multicultural family home-visit instructors and the influence of optimism and self-esteem on self-leadership. 668 home-visit instructors participated in the online survey from 140 multicultural family support centers in Seoul, 6 metropolitan cities, 9 provinces, and other cities and counties. Data were analyzed through frequence, percentages, Pearson's correlations, One-way ANOVA, $Scheff{\acute{e}}$ post-hoc test, and stepwise multi-regression using SPSS 21.0. The main findings are as follows. First, there were significant differences in optimism and self-esteem according to age and monthly income. Second, there were significant differences in self-leadership according to age and home-visit teaching experiences. Third, the stepwise multiple regression model showed that optimism, self-esteem and the individual variables had an influence on the self-leadership of home-visit instructor's self-expectation. These results suggest that self-esteem and optimism are important precursors of self-leadership and self-leadership training based on self-esteem and optimism is necessary for self-leadership enhancement of home-visit instructors.

The effects of culture depth (2-10 cm) and cell density on the growth rate and biomass productivity of Chlorella sp. XQ-200419 were investigated through the use of a self-designed open circular pond photobioreactor-imitation system. With increases in culture depths from 2 to 10 cm, the growth rate decreased significantly from 1.08 /d to 0.39 /d. However, the biomass productivity only increased slightly from 8.41 to 11.22 $g/m^2/d$. The biomass productivity (11.08 $g/m^2/d$) achieved in 4 cm culture with an initial $OD_{540}$ of 0.95 was similar to that achieved in 10 cm culture with an initial $OD_{540}$ of 0.5. In addition, the duration of maximal areal productivity at a 4 cm depth was prolonged from 1 to 4 days, a finding that was also similar to that of the culture at a 10 cm depth. In both cases, the initial areal biomass densities were identical. Based on these results and previous studies, it can be concluded that the influence of culture depth and cell density on areal biomass productivity is actually due to different areal biomass densities. Under suitable conditions, there are a range of optimal biomass densities, and areal biomass productivity reaches its maximum when the biomass density is within these optimal ranges. Otherwise, biomass productivity will decrease. Therefore, a key factor for high biomass productivity is to maintain an optimal biomass density.

A numerical investigation to simulate the selective growth of silicon-germanium quantum-dots via local surface diffusivity enhancement is presented. A nonlinear equation for the waviness evolution of film surface is derived to consider the effects of spatially-varying diffusivity, influenced by a surface temperature profile. Results show that the morphology of the initially planar film shapes into an undulated surface upon perturbation, and a steady-state solution describes a fully grown quantum-dot. The present study points toward a fabrication technique that can obtain selectivity for self-assembly.

The purpose of this study is to shed light on the driving motivations of contributing social word of mouth on social networking sites (sWOM) toward both tangible and intangible products. In order to develop a research model, this study adopts the motivation theory and TAM model. Data was collected from 904 members of the cosmetic and restaurant communities by using the snowball method. After assessing the validity of all constructs, the structural equation modeling (SEM) is used to test the proposed hypotheses. Results show that personal motivations (satisfaction, opinion leadership, self-enhancement, and economic incentives) and characteristics of sWOM (Perceived Usefulness and Ease of Use) have positive effect on exposure and engagement behaviors. Here are our specific findings, (1) customer satisfaction positively affects online interactions on SNSs such as Like or Sharing a content; (2) sWOM contribution behavior exists in two structures (Exposure and Engagement) and affects each other; (3) This study combines two groups of personal motivation and TAM to conceptualize a research model; and (4) The motivations of contributing sWOM between a specified service and product are rather similar. These findings help digital managers to understand consumers' behavioral contributions on SNSs and also provide interesting insights for marketers.

Entrepreneurial self-efficacy is an important variable that explains people's attitudes and behaviors toward start-ups. In this study, we focused on individual psychological characteristics variables such as luck in belief and positive cognitive bias that affect entrepreneurial self-efficacy. Among these variables, we paid particular attention to luck in belief. The belief that business success depends on luck is widespread, but scientific verification about it has not been much. The reason for the academic indifference is that luck is a kind of superstition, related to precognition or extrasensory perception, and randomly caused by the external environment. The study of luck began in earnest as a measure to measure luck as an individual characteristic variable such as personality was developed. The purpose of this study is to examine the existing studies on luck in belief and to examine the effect of this luck in belief on positive cognitive bias and entrepreneurial self-efficacy through empirical analysis. For empirical analysis, this study conducted an on-line survey of 400 ordinary people and conducted a structural equation model analysis using AMOS 21.0 to verify the hypothesis. As a result of hypothesis testing, all hypotheses that luck in belief would have a positive effect on positive cognitive bias(self-enhancement bias, illusion of control bias, unrealism optimistic bias) were adopted. The hypothesis that positive cognitive bias(self-enhancement bias, illusion of control bias, unrealistic optimism bias) will have a positive effect on entrepreneurial self-efficacy was also adopted. Additional analysis was conducted to examine the mediating role of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy, which showed that 'luck in belief→positive cognitive bias →entrepreneurial self-efficacy' were statistically significant. Through this, we confirmed the mediating effect of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy. In the conclusion, the implications and limitations of the study were presented based on the results of this study.

This study aimed to investigate the effects a strengths-based group counselling program had on self-esteem and career maturity of adolescents under probation. The subjects of the study were female adolescents under probation in Gwangju and were categorized into two groups: experiment group and control group consisting of 15 respectively. As a result, it was discovered that the strengths-based group counselling program had positive effects on enhancement of general and social self-esteem in the subjects while it did not have statistically significant effects on enhancement of family self-esteem. It indicates that positive relationship with parents and recovery of family functions should be encouraged to enhance the family self-esteem. Also, the strengths-based group counselling program had positive effects on planning, self-understanding, career knowledge and career preparation areas relating to career maturity while it did not have statistically significant effects on independence. It shows that to encourage the subjects to be independently prepared for career, family and society should provide more specific support for career guidance. Based on the results above, it was suggested that the strengths-based group counselling program had significant effects on self-esteem and career maturity of the subjects under probation. In conclusion, to encourage adolescents under probation to respect themselves and others, specifically plan their career and grow to be reliable and mature adults, further research on the strengths-based group counselling program is needed and diverse strategies including specific support through mentor service of college students should be developed.

The purposes of this study were to develop the empowerment education program, to describe the experiences of diabetes patient's empowerment process and to develop a theoretical model of the diabetes patient's empowerment process. Method 1. : The development of the empowerment program for the diabetes patients: The strategies of the empowerment education program were enhancement of problem - solving, decision making, self-efficacy, self-control. participation and mutual support. Method 2. : According to the grounded theory methodology of Strauss and Corbin, the qualitative data was collected with in depth interviews and participants observations until its saturation when the 25 consented subjects were participating and interacting with the other subjects in the empowerment education program. Results: With the analysis of the data, 29 categories were generated. The core category generated, which was a central phenomenon of the empowerment process, was named powerlessness. The intervening conditions facilitating or impeding the empowerment process were discovered as supportive systems through the participation of group meeting, problem solving dialogue, and the knowledge deficit of self-care. The action/interaction strategies were developed as the paricipating, dialoguing, questioning, supporting system, self-controlling, self efficacy, enhancing self-esteem. stress relaxing and instillation of hope.
