In this study, to explore the psychological and biosocial characteristics of the temperament and character's latent profile group, first, the latent group was identified with the seven variables of the Temperament and Character Inventory(TCI), and second, the difference between the psychological and biosocial characteristics of three identified latent groups. A total of 287 university students participated, and the latent groups was identified through latent profile analysis, a human-centeted statistical method, using Cloninger's TCI, Cognitive Emotion Regulation Questionnaire(CERQ), Positive Affect and Negative Affect Schedule(PANAS), Composite Scale of Moriningness(CSM), Pittsburgh Sleep Qulity Index(PSQI), and Satisfaction With Life Scale(SWLS). As result, first, three latent groups were identified through latent profile analysis using the seven variables of TCI. second, significant differences were identified in CERQ, PANAS, which are psychological variables, CSM, PSQI, and SWLS, which are biosocial variables among the latent groups. In conclusion, the importance of Self-Directedness(SD), a character factor that can be developed rather than Harm-Avoidance(HA), a temperament factor from nature, was confirmed. And the necessity of follow-up studies on psychological and biosocial variables for adaptive and mature personality was discussed.

A method of constructing a war simulation based on Bayesian Inference was proposed as a method of constructing heterogeneous historical war data obtained with a time difference into a single model. A method of applying a linear regression model can be considered as a method of predicting future battles by analyzing historical war results. However it is not appropriate for two heterogeneous types of historical data that reflect changes in the battlefield environment due to different times to be suitable as a single linear regression model and violation of the model's assumptions. To resolve these problems a Bayesian inference method was proposed to obtain a post-distribution by assuming the data from the previous era as a non-informative prior distribution and to infer the final posterior distribution by using it as a prior distribution to analyze the data obtained from the next era. Another advantage of the Bayesian inference method is that the results sampled by the Markov Chain Monte Carlo method can be used to infer posterior distribution or posterior predictive distribution reflecting uncertainty. In this way, it has the advantage of not only being able to utilize a variety of information rather than analyzing it with a classical linear regression model, but also continuing to update the model by reflecting additional data obtained in the future.

This study aimed at public officials who are most strongly demanded to tear up the corruption and diagnosed what they really think about 'the corruption'. So, a qualitative research method called 'subjectivity study' or 'Q methodology' was used to typing on the perception of corruption. In other words, 30 Q-samples related to corruption and P-samples composed of 30 public officials were investigated to derive the analysis results. As a result of the analysis, three types of perceptions of corruption were defined. That is, showed a high distribution of civil servants such as 'educational administration' and 'teacher', and and showed a high distribution of 'general administrative positions' civil servants. Also, among the respondents of , it was found that the distribution of 'high' was higher for the level of corruption in our society, and the distribution of 'medium' for and was found in the case of the respondents with high factor weight. The overall explanatory power was high at 62.11%, and based on the series of results, a hypothesis could be found that 'the perception of corruption differs according to the characteristics of the work of public officials'. By the results, the commonly recognized terms for 'corruption' were 'politician/politician' and 'solicitation'. Therefore, based on a series of results, this study is expected to be the 'Priming' for finding ways to move toward a more transparent society by diagnosing and reflecting on the thoughts of corruption in our society once again.

해마다 증가하고 있는 피서철 해수욕장 안전사고 및 비선박 사고의 감소를 위해 본고에서는 연안해역정밀조사 자료를 활용한 해양안전지도의 제작 및 체감형서비스를 구축하여 서비스하는 방안을 마련하였다. 해양안전에 관련한 각종 자료를 수집, 현장조사, GPS측량, 전문가 및 현지주민의 인터뷰 등을 통해 취득하였다. 서비스에 이용될 기본 배경지도로는 5m급 육상 지형기복도와 국립해양조사원의 수심자료를 사용한 해저지형기복도를 융합하여 제작, 이용하였다. 각종 해양안전관련 정보들은 해양영토(구역), 어촌양식, 항로, 각종사고이력, 시설, 위험요소 등 해양안전과 관련한 총 26종의 다양한 분류체계를 구성하여 구축하였다. 이렇게 수집, 구축된 기본 해양공간정보들을 바탕으로 사용자에게 정보의 전달성을 고려하여 국민이 간접적으로 체감할 수 있는 형태의 사이트(해수욕장 등)별 도면 형태의 해양안전지도를 제작하고, 개방형 대국민 해양공간정보 웹서비스인 '개방해(海)', 해양전문 공공기관용 웹서비스인 '공유해(海)' 대국민 해야안전정보 앱서비스 안전해(海)'와 시스템들을 구축하여 서비스 방안을 구축하였다. 각 서비스에는 해양안전사고 예방을 위한 각종 안전 및 위험정보 콘텐츠들을 수록하였고, 목적에 따라 이용가능한 분석 기능들을 제공하였으며, 위험구역에 노출될 경우 사용자간 위험을 알려주는 알림 기능 등을 제공함으로써 위험에 노출되고 조치하는데 도움을 줄 수 있도록 하였다. 그 결과, 현재 각종 기관에서 해양공간정보의 이용을 확대하고자 연계신청 증가와 더불어, 대국민 서비스 이용자수가 증가하는 실적을 기록하였으며, 향후 보다 광범위한 영역에서 안전사고, 안전대응, 안전관리 등의 분야에서 대책 도구로 활용이 가능할 것으로 기대된다.

In this paper, we have described a survey of applications and results of serious games for science education in elementary and middle school students. We constructed the educational contents and curriculum for learning natural science principles through game contents by analyzing science course of elementary and middle schools. Based on this curriculum, we developed science educational serious games 'Science Heroes' to help teaching-learning difficulty caused by abstract science concepts or spatial-temporal limitation. In our research, we carried out a serious game evaluation test for our game contents by current teachers about applicability to the real education field and supplementary points.
