The purpose of this study was to examine the impact of psychosocial protective and risk factors on problem drinking among American adolescents. In addition, this study investigated the compensatory and buffering effects of psychosocial protective factors. The sample consisted 4,362 10th graders taken from the Monitoring the Future Study 2002. This study performed the hierarchical regression analysis for data analyses. The main findings provided that friend influence, sensation-seeking, and tolerance of deviance had significant positive relationships with problem drinking as risk factors. This study also revealed that negative perception on drinking, parental bonding, school bonding, and prosocial activity had significant direct impacts in decreasing problem drinking, which explains the compensatory effect of protective factors. Additionally, this study showed that negative perception on drinking had a significant buffering effect moderating friend influence on adolescents' opportunities exposed to problem drinking. The results of this study suggest some practical implications for preventive intervention programs that target adolescent problem drinking.

In recent years, as interest in youth startup has increased, the Korean government has established various policies to support young entrepreneurs and actively implements such policies. Especially, as a way to promote youth startup, the development of startup clubs in universities is being suggested, and the importance of startup clubs is growing day by day. As reflected in these points, the Korean government is increasing its budget every year to support the startup clubs of universities, and actively supports the funds and space required for the startup clubs of universities. Unfortunately, however, despite the growing importance of startup clubs and the active support of the government for the startup clubs, academic attempts to see how effectively the startup clubs are operating are not enough. For this reason, this study analyzes the effect of entrepreneurship of university start-up club members on the effectiveness of start-up club. More specifically, in this study, entrepreneurship of club members is classified as risk-taking propensity, proactiveness, and innovativeness, as emphasized in previous researches. We empirically analyzed the effects of these independent variables on the effectiveness of the start-up clubs, focusing on the moderating effect of club members' diversity. We conducted empirical analyses on 1112 start-up club members from 12 universities located in Jeollanam-do and Jeollabuk-do, and the analysis results are as follows. First, the entrepreneurship of the start-up club members, namely risk taking propensity, proactiveness and innovativeness, all have a positive effect on the effectiveness of the start-up club. These results are consistent with the emphasis of many previous studies. The higher the tendency to take risks, the more inclined to move forward through difficulties, and the higher the tendency to break out of the existing framework and pursue new things, suggesting that the effectiveness of the club is enhanced. Second, as a result of verifying the moderating effect of the club members' diversity, it was found that club members' diversity moderates the relationship between the proactiveness of club members and club effectiveness in the negative (-) direction. In other words, the positive effect of the entrepreneurship of club members on the effectiveness of the start-up club means that the proactiveness is weakened in the case of a club having members from different major backgrounds. The results of this study are expected to provide meaningful theoretical and practical implications by identifying the influencing factors of the start-up club's effectiveness, which has not received much attention so far.

The purpose of this study was to investigate Korean undergraduate students' metacognitive awareness and preference of effective learning strategies. To achieve this goal, a scenario-based survey was conducted focusing on the metacognitive awareness, preference, and use of seven effective learning strategies (modality effect, static-media presentations, absence of extraneous details, testing, distributed learning, interleaved learning, generation) that were empirically supported. This study also aimed to explore the relationships between grade point average (GPA), metacognitive self-regulation, and the aforementioned variables to investigate which students know about, prefer, and use effective learning strategies. The majority of students were unknowledgeable about four of the seven strategies (modality effect, static-media presentations, absence of extraneous details, interleaved learning). Only half of the students were correctly aware of effectiveness of the two strategies (testing, generation). Moreover, students showed low preference for effective learning strategies. GPA did not show a significant correlation with metacognitive awareness and preference of effective learning strategies; however, it showed a significant positive correlation with the use of effective learning strategies. Only for a few learning strategies, metacognitive self-regulation showed a positive correlation with metacognitive awareness, preference, and/or their use. This study suggests that it is important to teach effective learning strategies to undergraduates with a specific direction of instruction. In addition, this study distinguishes metacognitive awareness from preference, suggesting that these two may reflect different constructs.

The purpose of this study was to identify the mediating effect of anger expression between covert narcissism and SNS addiction proneness. It was conducted to measure anger expression, covert narcissism, and SNS addiction proneness from 252(132 male, 120 female) university students. The mediating effect was analyzed through Preacher and Hayes' SPSS Macro and bootstrapping analysis. As a result of analysis, first, there were positive relationship among covert narcissism, anger expression, and SNS addiction proneness. Second, anger-out had significant mediating effect within the relationship of covert narcissism and SNS addiction proneness. Third, anger-out had significant mediating effect within the relationship of covert narcissism and disturbance of adaptive life and control failure, preoccupation and tolerance, avoidance of negative emotions. Forth, anger-in and anger-control had significant mediating effect within the relationship of covert narcissism and virtual life orientation and withdrawal. Implications of these results were explored in relation to the importance of covert narcissism and SNS addiction proneness. In addition, this implication and suggestions for future research are provided.

The government is working out the development of a venture enterprise through a venture certification system. The broad effects of its policies are anticipated by the government and revealed in the 'The Survey on Actual Condition of Venture Enterprises 2010'. These benefits include the revitalization of start-up, promotion of technological innovation, progress in marketing ability, improvement in corporate image, financing and investment, and benefit from tax reduction & exemption. However, with the estimation of production function and sales function, which both uses capital and labor as a basic elements, it was found that only 'financing and ease of investment' produces a statistically significant effect on production and sales. An addition, this study looks into whether venture-supporting system are helpful to the eradication of technical inefficiency. The policies brought about positive changes in reduction of technical inefficiencies except with regard to the ease of start-up where it was found that an increase in inefficiencies was the result.

발생중인 계배의 날개형성에 미치는 retinoic acid(RA)의 효과를 알아보았다. RA처리는 날개원기의 전단부로 부처 거울상을 띤 지골의 복제를 유발하였다. 이러한 RA처리에 따른 지골의 복제 효과는 발생시기 및 처리량에 의존적이었다. 즉 stage 18시기의 날개원기에 RA를 처리했을 때 최대의 지골 복제 효과가 유발되었으며, 20mg/ml 의 RA 용액으로 처리했을 때 최대의 지골 복제 효과가 나타났다. 이러한 실험결과는 RA 처리가 날개원기 세포의 positional value를 전후축 상에서 후위화하기 때문에 나타나는 것으로 해석될 수 있으며, 후위화의 정도는 발생단계 및 처리량에 의존적임을 시사하고 있다.
