Career development of Korean Immigrant Adolescents is important element for their Korea social adjustment and reduction of social exclusion. Especially, vocational identity is considered significantly for their career development. This study investigated the relationships and levels of discrimination, depression, self-esteem on vocational identity by comparing Korean immigrant adolescents and non-Immigrant adolescents(Korean parents family: non poor family or poor family). The major findings of this study can be summarized as follows. First, the depression level of immigrant adolescents is higher than non poor family adolescents and their self-esteem level is lower than non poor family adolescents by means analysis. second, The path analysis and multi group analysis showed that the degree of discrimination by perceived immigrant adolescents had direct influence on vocational identity and also mediated depression, self-esteem as indirect influence. But non poor family adolescents and poor family adolescents showed that their degree of discrimination had only indirect influence on vocational identity as mediation of depression, self-esteem. The result of analysis were used to discuss theoretical, practical implication for career development of Korea immigrant adolescents.

This study aimed to investigate the effect of adolescent development environment including parenting attitude, peer relationship, and school environment on delinquent behavior, and between these relationships, the mediate effect of media environment such as computer and mobile devices. The $6^{th}$ year data from Korean Children & Youth Panel Survey (KCYPS) was used and the subjects were limited to 518 students of $7^{th}$ grade who are in their early adolescence. The result shows that adolescents under more affectionate, over involvement, and abusive parenting attitude will commit delinquent behaviors more frequently, and so does alienated youth from their friends. Parenting inconsistency and communication with friends make them use computer and cell phone more often, and excessive media usage increases adolescent's delinquent behavior. In conclusion, family environment and peer relation have influence on adolescents' delinquent behavior. Therefore, there is necessity to build development environment that prevent adolescents' delinquencies like parent education program or peer communication program for example. Also, proper education program for using computer or cell phone usage can reduce adolescents' delinquent behaviors, especially when its addictive aspect was recently issued.

The impacts of internal marketing in the security firms have not been studied much. This study analyzes the impact of internal marketing on job satisfaction, job commitment, customer orientation, and job performance for the security firm's branches using multiple mediation model which differs from simple mediation model. The data were collected from 263 employees of securities firm's branches in Seoul, Busan and other Korean metropolitan cities. The research hypothesis was validated by the tools of SPSS 22.0 and AMOS 22.0. The results are as follows. First, among the internal marketing factors, delegation of authority, reward systems and education training had a significant effect on job satisfaction. And internal communications were shown to have a significant effect on job commitment and customer orientation. Second, job satisfaction have a significant direct impact on the job commitment, customer orientation. And customer orientation have direct impact on the job performance. Also, delegation of authority and reward systems were found to have a significant indirect effect on the job performance in mediation of job satisfaction and customer orientation. These results imply that internal marketing factors affect job performance mainly through the mediation of job satisfaction, job orientation and that specially delegation of authority and reward system affect on the performance much, which are different from other industry cases.

This study aims to investigate the influence of the components of the startup ecosystem on the business performance of startups, focusing on the mediating effect of the location environment. By presenting the insight that the popularization of start-ups can be an alternative for job creation thanks to the government's start-up support policy considering the location environment, it is possible to construct an optimal configuration scenario between the components of the start-up ecosystem and the location environment. Furthermore, it is expected to contribute to the improvement of corporate management performance. To achieve this goal, we performed a survey and the subjects were domestic start-up company employees with less than 7 years of experience. The results show that the components of the start-up ecosystem had a significant effect on the business performance of start-up companies and the location environment and on the management performance of start-up companies according to the mediation of the location environment.

This study explored the role of perceived stress in Korean high school students' suicidal thought. In so doing, we also investigated the mediating role of high school students' internet use time and amount of drinking alcohol. For this, 2019 Korean adolescent health behavior survey was used. Complex design multivariage logistic regression analysis revealed that high school students' perceived stresss(OR:5.607, 95%CI:5.077-6.191) and amount of drinking(ranging from OR:1.412, 95%CI:1.159-1.720 to OR:2.325, 95%CI:1.928-2.803) played a significant role in their suicidal thoughts. Internet use time and amount of alcohol consumed were found to play a mediating role. Implications of the results are discussed. Therefore, since internet use mediated suicidal thinking among adolescents, it is necessary to develop a intervention program or message for them.

Human prostatic acid phosphatase (PAP), with comprehensive homology to glandular kallikrein, are representative serum biomarkers of prostate cancer. Dendritic cell (DC), which is the potent antigen-presenting cells(APC) in the immune system, can induce strong T cell responses against viruses, microbial pathogens, and tumors. Therefore, the immunization using DC loaded with tumor-associated antigens is a powerful method for inducing anti-tumor immunity. The CTP (Cytoplasmic Transduction Peptide) technology developed by Creagene which can transport attached bio-polymers like nucleic acids or proteins into the cell with high permeation efficiency. As the active forms of PAP can mediate apoptotic processing, we used multimer forms of PAP as an inactive form for antigen pulsing of DCs. In this study, multimeric forms of CTP-rhPAP was obtained according to the advanced purification process and subsequently confirmed by gel filtration chromatography, western blot and Dynamic Light Scattering. Therefore, CTP-conjugated PA multimers transduced into the cytoplasm were efficiently presented on the cell surface without any harm effect on cells via MHC class I molecules and result in induction of a large number of effector cell.

Inscriptions are integral parts of the current science textbooks, and become medium that makes sense of scientific concepts effectively. This study analyzed the inscriptions from five science textbooks at the secondary level in terms of its type, function, and structures. Analyzing types of inscriptions resulted that the ratio of frequently used photographs and illustrations were much higher than that of graphs and tables used. In case of function analysis, illustrative and complementary functions were dominant in terms of frequency and ratio, whereas explanatory, decorative and inquisitive functions were relatively rare. Inscriptions of single structure was much more than multiple structure. Multiple structure of pair and series were mainly used for representing contrast and sequence, respectively. The proportion of inscriptions in type, function and structure across the textbooks was significantly different. Based on the results, it was suggested that semiotic study about the function and the structure of inscriptions need to be carried out in earth science area to better understand the pedagogical implications of inscriptions in school science.
