The purpose of this study was to investigate the effects of social support on career maturity and self-reliance of inmates in a juvenile reformatory. This survey was administered to the adolescents in S juvenile reformatory, which represents juvenile reformatory across the nation. Statistical analysis were performed using SPSS 22.0 for 115 complete responses. Results are as follows: First, the effects of social support on career maturity was found to be statistically significant, $R^2=.411$, p<.001. That is, support by friends and religious program personnel remained a significant influence on career maturity, after controlling for sociodemographic variables. Second, the effects of social support on self-reliance was also found to be statistically significant, $R^2=.520$, p<.001. It was shown that the support of friends and family as dependent variables, had statistically significant effects on self-reliance. The results of this study suggest the need to expand programs that reinforce support by friends, a meaningful variable, along with the need to seek and link available resources within the local community in order to build social support systems. It is also necessary to establish education and related organizations to provide effective socail support.

The sand shrimp, Crangon hakodatei commonly occured in the southern coast of Korea. The population structure, growth, mortality, and size at sexual maturity of C. hakodatei were examined by the samples collected from the coastal area of Geoje Island, Korea from October 2000 to October 2001. For estimation of parameters of growth and mortality, monthly length-frequency data were analysed by ELEFAN. Parameters of growth were estimated, using the modified yon Bertalanffy growth function model. The female grew faster and reached larger size at the same age than the male, There was a breeding season showing a peak in winter (January to february). Total mortality by length-converted catch curve was estimated at $3.10 yr^{-1}$, fishing mortality was $0.62 y^{-1}$ and natural mortality was $2.48 yr^{-1}$. The size at $50\%$ sexual maturity for the female ranged from CL 11.00 to 11.50 mm.

The reliability used as a performance indicator during the development of space launch vehicle should be validated by the launch success probability, and the launch data need to be fed back for reliability management. In this paper, the launch data of space launch vehicles around the world were investigated and statistically analyzed for the success probabilities according to the launch vehicle models and maturity. The Bayesian estimation of launch success probability was reviewed and analyzed by comparing the estimated success probabilities using several prior distributions and the statistical success probability. We presented the method of generating prior distribution function and considerations for Bayesian estimation.

This study analyzed statistically the determinants that affect the royalties of knowledge technology transfer, which accounts for a considerable portion of university technology transfer. As knowledge technology transfer certainly includes a move from tacit knowledge from one side to the other side per se, the scope of knowledge technology transfer is unclear and numerical information of technology transfer, such as research fund scale, which is used widely in previous studies, cannot be used in the analysis. Therefore, this study focused on the researcher characteristics and included its explanatory variables in the present study. In addition, it included the technical characteristics of the knowledge transferred and the characteristics of the contracting company. The knowledge maturity calculated from the appointment year and contract date positively affects the technology royalties, but work experience and patent activity of the researcher are not statistically significant. Statistically significant differences in the technology royalty according to the type of technology transfer and the company location were observed, but there was no meaningful change in the technology royalty depending on the technical field and company business scale.

This study requires SW education that can adapt to the advent of the fourth industrial revolution and the new normal environment of COVID-19 pandemic. Small and powerful smartphones, which have become a necessity in digital society, are designed and applied to create apps with useful apps or artificial intelligence modules that have been trained with data using the App Inventor program as a good teaching tool. After conducting the class in a blended method that combines face-to-face and non-face methods, the survey questioned the technical and cognitive maturity of artificial intelligence and the pros and cons of blended software classes. We also found changes in career orientation, which is intended to explore SW-related talent occupations that require a lot of demand in terms of national development before and after artificial intelligence classes. Significant results were reached in three of the sub-elements. Even in non-face-to-face situations, it is expected that an app vendor software education program using artificial intelligence will be provided to the actual site.

IT outsourcing becomes one of the important shills for managing diverse and complex information systems, SIA is considered as an one of the success factors for the successful outsourcing management. Since it helps to establish common goal and provides better visibility of trends and performance, the SLA process must go beyond mere measurement to include a methodology for the ongoing management of service levels, and for the continuous improvement of service activities, functions and processes. Despite SLA is one of the most important skills for the successful outsourcing, few studies have been conducted for academic as well as practical purpose. For this reason, The objective of this study is to develop an SLA's maturity model and empirically demonstrate how SLA's maturity level affects its Performance through SLA's maturity model. The major contributions of this study are in two areas. This study contributes to academicians as well as practitioners. First, from the academic perspectives this study tries investigating the maturity level of the SLA based on empirical data. Second, practitioners can self-test their firms' maturity level using the proposed model. The results of this study show that the SLA's maturity level affected positively SLA's performance. It is founded that the SLA's maturity level had a significant impact on SLA's performance.

This research aims to develope a maturity evaluation model on the technology management competence (MEMTMC) and to investigate the relationship between technology management competencies and maturity evaluation level in Korean firms. After research framework building through literature review and field study focusing on interview process, a maturity evaluation model was suggested, including technology management competency factors such as vision and strategy, leadership, resources, projects, performance management, and systematic procedures. Through the empirical study on the 111 Korean firms, the MEMTMC model was tested and some hypotheses were examined. As a result of the research, we found that the MEMTMC is significant statistically to evaluate the technology management competencies of firms from a practical point of view. Additionally, these findings suggest that firms can build up their technology management competencies, including the vision and strategy, leadership, resources, projects, performance management, and systematic procedures in order to raise their maturity level of technology management competencies. But this research has some limitations such as this MEMTMC has not considered separately the variety of industry, not enough survey respondents and 5 level group firms etc.
