Giant character used various SF movies and games in media convergence ages, and is essential for giant character in success contents. It This study defined giant character of SF movies and games, it analysed the eight of external characteristics and internal characteristics of giant character in SF movies and games. The external characteristics defined shape, silhouette, size and color, the internal characteristics defined fear, satanism, image and story focus, playfulness. Above, it was structured positioning model of giant character based eight characteristics and analyzation of example of SF movies and games. The elements of positioning model of giant characters are darkness, huge, abnormal, human, animal, fear, satanism, story focused, image focused and playfulness, and this study was proposed these model of elements of eight in SF movies and games.

The external quality factor ($Q_e$) is controlled by coupling condition between resonator and input/output ports in design of microwave filter. In this paper, we represent extracting method of external quality factor using phase response for resonator with input/output ports according to position of feed line from microstrip line resonator. The results regarding to position, coupling gap and line width for tapped line and coupled line structure are represented, and we got the exact $Q_e$ value from the this method. This results will be applied to coupled resonator filter design.

Previous research have demonstrated that the external factors (ex., money, appearance) are more influential in Easterners' self-views and conditions for happiness than those of Westerners'. Based on these results, the current study examined whether 1) children and adolescents acquired these tendency as they grew up and 2) this tendency had relevance with social comparison. Total 954 students (260 elementary, 216 middle school, 260 high school and 218 college students) participated in the study. The results showed that elementary and middle school students regarded the internal factors (ex., thinking, feeling) as more important. But high school students considered the external factors as more important, and there was no difference in college students. Also, the results revealed that elementary and middle school students regarded the harmony of family and peace of mind as more important conditions for happiness. These results contrasted with preference for better educational backgrounds, better occupation, and money in high school and college students. In addition, age and social comparison tendency had positive relation with external self-concepts and negative relation with self-esteem. Especially, high school students showed strongest external self-concepts and social comparison tendency among four age groups. They also showed strongest preference for external conditions for happiness, but their self-esteem was the lowest. This might reflect fierce competition for college education in Korea, and the results of the current study have demonstrated that adolescents developed a tendency to prefer external factors to internal factors as they grew up in a competitive environment.

최근 국내외적으로 지구온난화, 산성비, 오존층파괴 등의 환경문제가 심각하게 대두되기 시작하면서 화석연료 사용에 대한 규제가 점차적으로 강화되고 있다. 이와같은 상황에서 기존의 미분탄 화력발전시스템에 비해서 NOx, SOx, $CO_2$, 분진 등의 대기오염물질을 현저히 줄일 수 있으며 발전효율도 높아서 석탄 사용에 따른 지구의 환경오염 저감과 에너지의 효율적인 이용 측면에서 석탄가스화 복합발전 시스템은 청정석탄 이용기술로 크게 관심을 모으고 있어서 국내외적으로 관련연구가 활발히 진행중이다.(중략)

본 연구에서는 아파트를 대표할 수 있는 내·외적 데이터를 수집하고 인공지능 기술들을 활용하여 아파트 가격을 예측하는 시스템을 구축하고자 한다. 구체적으로 웹크롤링 기법을 통해 수집한 아파트 내·외적 데이터의 변수들에 대한 특성 선택(Feature Selection)을 수행하였고, 다양한 인공지능 기법을 활용하여 부동산 가격 예측 모형을 개발하였다. 아파트 가격 예측 모형 생성을 위해 Linear Regression, Ridge, Xgboost, Lightgbm, Catboost 등의 기계학습 알고리즘을 사용하였고, RMSE를 사용하여 각 예측 모형 간의 성능 비교를 수행하였다. 가장 성능이 좋은 예측 모형은 Xgboost기반 예측 모형이였으며, RMSE값이 약 0.0366으로 가장 낮았으며 테스트 데이터에 대한 정확도는 약 95.1%였다.

최근 초경량 직물에 나일론 Spiral Crimp 신축소재에 많이 사용되어지는 Mechanical 신축성 직물이 시판되고 있으나 신축특성의 저하, 품질 저하의 문제점이 대두되고 있어 아직까지 본격적으로는 상용화되지 못하고 있고 국내외적으로 아직까지 나일론 세섬사 Spiral Crimp 신축소재개발과 관련된 기술개발은 전무한 실정이다. 따라서 본 연구에서는 현재까지 국내외적으로 개발되지 못한 스포츠 아웃도어용 경량직물의 Mechanical 신축성 초경량 직물을 개발하기 위해서 중합단계에서 나일론 개질 폴리머를 개발하고, 수축 특성이 서로 다른 2종의 나일론 폴리머를 이용하여 side by side 형태로 세섬 복합방사와 사가공 및 연신 단계에서 2d급 Spiral Crimp 및 Super Bulky특성이 우수한 신축성 소재를 개발하여 이들의 구조와 물성을 조사 검토하여 이를 실제 현장에 자료를 제공하는 것을 목적으로 하였다.

The purpose of this study is to study internal and external factors affecting entrepreneurial intention of korean professional soldiers who are supposed to retire less than one year. Another main focus of this study is to find out whether there is mediating effect of entrepreneurial support programs for entrepreneurial intentions. In this research, data were collected from 361 officers and non-commission officers who are scheduled to retire from the military within 5 months to one year after at least 10 years of military service. The collected data were analyzed by SPSS using the regression analysis method. In this study, we found that internal factors did not positively affect entrepreneurial intentions, however, external factors positively affected entrepreneurial intentions. It was also found that entrepreneurial support programs played important role as moderating variables between social perceptions toward entrepreneurs and their entrepreneurial intentions. Based on these findings, implications of research implications are discussed, and recommendations for future research were provided.

The work-related values are important to understand the organizational members' behavior. Because they lay the foundation for understanding of attitudes and motivation. This study aims at developing and empirically testing a comprehensive model of work-related values. The study seeks to understand the relationship between work-related values and job performance. A questionnaire survey method is adopted to collect the data for this study. Correlations and moderated regression analysis are used to verify the proposed hypotheses. Pride in work, job involvement, and activity preference are correlated positively with job satisfaction and organization commitment. The attitude toward earnings and social status of job are negatively correlated with job satisfaction and organization commitment. But upward striving is positively correlated with organization commitment.
