The purpose of this study was to examine the relationships between perceived parental attachment and the life satisfaction of college students, focusing on the mediating role of psychological basic needs(autonomy, competence and relatedness). The Participants of this study were 208 college students. The result was statistically treated using SPSS 21.0 program, Amos 21.0. Additionally, PROCESS Macro was used to verify the significant mediating effect. Results from structural equation modeling analyses indicated that a research model produced a better fit to the data than a alternative structural model. The final SEM model fit indices of $x^2$(df), CFI, TLI, RMSEA were met the acceptable criteria of model fitness. In other words, among the goodness-of-fit indexes of the final study model, $x^2=261.075$(p<.001), RMSEA is .082, TLI equals .925, CFI equals .940. The results showed the following: First, Parental attachment has a direct effect on autonomy, competence and relatedness. Also competence and relatedness have a direct effect on the life satisfaction. Second, Competence and relatedness showed a mediating effects on Parental attachment and the life satisfaction. The implications of these results were discussed and the further studies were suggested.

The purpose of this study was to investigate the effect of adolescents' academic stress on academic burnout and academic engagement and the moderating effects of parental academic involvement behavior on the relation between academic stress, academic burnout and academic engagement. The main results of this study were as follows. First, adolescents' academic stress had an influence on academic burnout and academic engagement. The higher adolescents' academic stress was, the higher academic burnout and the lowerer academic engagement were. Second, adolescents'academic stress and parental adequacy results pursuit behavior influenced academic burnout. That is, the level of adolescents'academic stress and parental behavior encouraging academic progress of children caused the low academic burnout. And parental behavior encouraging academic progress of children appeared to have a moderating effect on the relation between academic stress and academic burnout. Third, adolescents'academic stress, parental behavior pursuing adequate result, encouraging academic progress and granting their children academic options influenced academic engagement. However, parental academic involvement behavior appeared not to have a moderating effect on the relation between academic stress and academic engagement.

The purpose of this study is to investigate the effect of educational satisfaction on the school conversion intention according to the quality of university education service. To survey the perception of students majoring in Department of Beauty on both colleges and universities of beauty education, we distributed 600 questionnaires and utilized them as final analysis data except for 60 unreturned or defective papers. As a result of t-test and one-way ANOVA, there were differences among university education service quality, education satisfaction and school transfer intention. In addition, the effect of the quality of education service on the education service, the effect of the quality of education service on the school conversion intention, and the quality of the university education service influenced the school conversion intention. The results of this study suggest that, for the development of the beauty education, priority should be given to the facilities and equipments related to the beauty education as well as the importance of leadership and professional teachers and instructors.

In this paper, we estimate the exchange rate exposure, indicating the effect of exchange rate movements on firm values, for a sample of 1,400 firms in seven East Asian countries. The exposure estimates based on various exchange rate variables, return horizons and a control variable are compared. A key result from our analysis is that the long term effect of exchange rate movements on firm values is greater than the short term effect. And we find very similar results from using other exchange rate variables such as the U.S. dollar exchange rate, etc. Second, we add exchange rate volatility as a control variable and find that the extent of exposure is not much changed. Third, we examine the changes in exposure to exchange rate volatility with an increase in return horizon. Consequently the ratio of firms with significant exposures increases with the return horizons. Interestingly, the increase of exposure with the return horizons is faster for exposure to volatility than for exposure to exchange rate itself. Taken as a whole, our findings suggest that the socalled "exposure puzzle" may be a matter of the methodology used to measure exposure.

This article deals with a Causal-Loop analysis of the characteristics of Ouroboros effects. The meaning of the effects is that solutions to problems are usually intended as final fixes, but more often than not, while solving one problem, they generate more problems. It means 'to worsen through attempts to make better.' The Ouroboros effects are very dangerous because they are regarded as a kind of self-destructive mechanisms. While existing researchers recognize the risks of the effects, they are not able to solve the systematic problem but only to describe the symptom. Such a way to deal with the effects results in difficulty to clarify the cause-and-effect relationship within the system. Thus the authors are focusing on explaining the effects by SD (System Dynamics), which are considered as the sole methodology to do effectively so far since SD is a great tool to discover structural causes. To solve the self-destructive problem of the effects, the authors analyze the characteristics of several cases of the effects in elaborating the CLD (Causal Loop Diagram) for each case. The analysis reveals the structural characteristics of the effects and how to correct them towards maintaining the sustainability of systems.

Purpose: The present study was designed to examine the casual relationships among performance and arts information service quality, initial trust, user satisfaction, reuse intention and prosumer activity in social network service(SNS). Also, we intended to explore significant factors on use performance of SNS through causal model analysis in the viewpoint of total effect. Methods: As a survey tool, questionnaire has obtained validity and reliability through literature survey, exploratory survey and pretest and sample 403 was selected. For statistical treatment of pretest and main analysis, SPSS18.0 and AMOS18.0 were employed and structural equation model was employed as analysis method. Results: Result of this study shows as follows. Two factors (precision and reciprocal action) have an effect on user satisfaction, initial trust, reuse intention and prosumer activity. We found that with an importance of initial trust, prosumer activity can be a useful and significant factor in causal relationship of SNS. Conclusion: The present study shows that two factors(precision and reciprocal action) in via of initial trust, were important factors that related companies have to emphasize to raise performance, And also we confirmed new factor 'prosumer activity' through this study. However, the present study has some limitations to be studied in the future.

Nowadays Cu2ZnSnS4 (CZTS) solar cell is attracting a lot of attention as a strong alternative to CIGS solar cell due to nontoxic and inexpensive constituent elements of CZTS. From various processes for the fabrication of CZTS solar cell, solution-based deposition of CZTS thin films is well-known non-vacuum process and many researchers are focusing on this method because of large-area deposition, high-throughput, and efficient material usage. Typically the solution-based process consists of two steps, coating of precursor solution and annealing of the precursor thin films. Unlike vacuum-based deposition, precursor solution contains unnecessary elements except Cu, Zn, Sn, and S in order to form high quality precursor thin films, and thus the precise control of precursor thin film preparation is essential for achieving high efficient CZTS solar cells. In this work, we have investigated the effect of preparation condition of CZTS precursor thin films on the performance of CZTS solar cells. The composition of CZTS precursor solution was controlled for obtaining optimized chemical composition of CZTS absorber layers for high-efficiency solar cells. Pre-annealing process of the CZTS precursor thin films was also investigated to confirm the effect of thermal treatment on chemical composition and carbon residues of CZTS absorber layers. The change of the morphology of CZTS precursor thin film by the preparation condition was also observed.

Objectives: The purpose of this study was to test the mediating effect of depression in the relationship between emotional labor and quality of sleep among dental hygienists. Methods: A purposive sample of 224 subjects in Seoul and Gyeonggi-do Province was recruited for convenient sampling. Data were analyzed using descriptive statistics, correlation, and multiple regression using Baron and Kenny steps for mediation. Results: The mean scores for overall emotional labor, quality of life, and depression were $33.14{\pm}5.55$, $7.49{\pm}2.82$, and $19.20{\pm}10.45$, respectively. They were significantly correlated with each other. Depression had a mediating effect(${\beta}=.52$, p<.001) in the relationship between emotional labor and quality of sleep(Sobel test: Z= 6.82, p =.001). Conclusions: The findings of this study suggest that intervention programs focusing on preventing depression are highly recommended to improve quality of life among dental hygienists in relation to emotional labor.

Although the study of post-adoption has increased in recent years, few studies have focused on the moderating effect of uncertainty avoidance on the relationship between post-expectation and behavior. The purpose of this study is to examine the moderating effect of uncertainty avoidance in the mobile Internet domains. This study proposed a post-adoption model based on prior continuance model. This theoretical model was verified empirically by conducting web surveys and multi-group analysis. Based on the survey data, we classified users into those with high uncertainty avoidance and those with low uncertainty avoidance. The results indicate that post expectations have significant impacts on satisfaction and continuance intention. The results also show that the impacts of intrinsic motivational factors of mobile Internet services on satisfaction and continuance intention are stronger for users with high uncertainty avoidance. On the other hand, the impacts of extrinsic motivational factors on satisfaction and continuance intention are stronger for users with low uncertainty avoidance, with a few exceptions. This paper ends with theoretical and managerial implications of the study results, as well as limitations and future research directions.

Purpose - This study investigated the effects of leaders of national universities on faculty creativity. The study examined transformational leadership and creativity theories and investigated self-efficacy, the parameter between transformational leadership and creativity, to examine its moderating effect and provide policy implications for national universities. Research design, data, and methodology - This study built four hypotheses based on the literature review, and tested these using a survey methodology. The collected data were analyzed using SPSS 15.0. Result - At the national universities, the results were as follows: charisma of leaders had a positive influence on member creativity; intellectual stimulus of leaders had a positive influence on member creativity; and, individual consideration of leaders had a positive influence on member creativity. Therefore, leaders' transformational leadership had a positive influence on member creativity. Conclusion - Creativity is thought to be important for organizational survival and continuous development at rapidly changing education administrations. Educational administration leaders should exercise transformational leadership to develop member creativity. Member self-efficacy, which had a mediating effect on creativity, requires leadership to develop it.
