가상 현실 미술관에서 시각적 요소인 해상도는 참여자에게 매우 중요한 인공현실감을 제공하며 실제 세계와의 상호 교류의 차이의 극복 요소로서 매우 중요한 부분으로 볼 수 있다. 이러한 시각적 측면을 중심으로 가상현실 전시관에서 관람객과 전시물 사이의 거리에 따른 감상 위치를 분석하고, avatar의 이동에 따른 원근법을 적용하여 해상도를 동적으로 변화시킨다. 특히, 가상 공간의 이동 예측 및 거리 측정에 따른 해상도의 변화는 현장감 향상에 도움을 준다.

Misconceptions are one of the most important and long-lasting studied themes on science education. It is because their nature is obstinate and settled as well as they corrupt students' understanding of science concepts. This study examines whether preservice elementary school teachers enrolled in biology teaching material research course changed positively on science teaching efficacy and correcting life science misconceptions when they used the handbook developed for this study. The handbook comprises 203 life science concepts surveyed among preservice teachers holding from advanced researches and arranged by 2007 Revised Science Curriculum. 107 preservice elementary school teachers participated in the study. Forty-six (46) of them were assigned to the experimental group and the other 61 to the control group. ANOVA was conducted for analyzing data. Science Teaching Efficacy Belief Instrument (STEBI) and the life science misconception test which was developed for this study, were administrated as assessing instruments for pretest and posttest. The experimental group, using the handbook, acquired higher scores in both tests on statistical significance level than the control group who were not using the handbook. The results indicate the handbook developed for correcting life science misconceptions for this study is effective in enhancing science teaching efficacy and correcting life science misconceptions.

The purpose of this study is to investigate the relationship between teacher's self-efficacy and teacher's leadership in kindergartens and child care centers. The subjects are 215 teachers employed in kindergartens or child care centers in Chungnam & Daejeon Metropolitan City. Questionnaires, which required self-reporting by teachers, are used to investigate teacher's self-efficacy and teacher's leadership. The data are analyzed by frequency, percent, Pearson's correlation and stepwise regression. The results of this study are as follow. First, teacher's self-efficacy is positively associated with teacher's leadership. Second, teacher's self-efficacy affect teacher's leadership.

The purpose of this study is to investigate the structural correlation between career decision making self-efficacy, major satisfaction and occupation value of beauty major students by questionnaire collection and statistical analysis. Major satisfaction was found to be statistically significant at the significance level of .05 with respect to coccupation value and career decision making self-efficacy at p<.001. Occupation value was found to be statistically significant at p<.001 for career decision and job decision of career decision making self-efficacy and significance level .05. Therefore, it has been confirmed that the major satisfaction and job value are the factors that play a significant role in the self-efficiency of career decisions, and it is believed that continuous research on various variables that affect the self-efficiency of career decisions of beauty major university students is necessary.

The purpose of this study is to develop a extracurricular programs for enhancing creative self-efficacy of college student based on design thinking process, and to examine the effectiveness of the developed program. Since this study is also interested in suggesting the procedure for extracurricular program development and optimizing programs by derivation of improvements, a design-based research method was applied. Results are as follow; first, the procedure for extracurricular program development proceeds in three stages, second, the programs was developed as a 30-hour in-depth program and was conducted twice during winter and summer vacation, and the last, the program was confirmed that it has a positive effect on improving creative self-efficacy. This study contributed to providing a general procedure that can be referred when developing a program that reflects the context of the university, and to present the specific program and the case that use the test tool to confirm the effectiveness.

An important feature of virtual reality is the facility for the user to move around a virtual environment in a natural and easily controlled manner, Navigation. Navigation involves changing the perspective of the user in the virtual environment (VE). Natural locomotion methods are able to contribute to a sense of presence and reality. This paper focuses on the navigation method in the virtual environment, one of the major interfaces for the interactivity between human and virtual environments in virtual reality circumstances and worlds. It proposes a new navigation method: Intelligent Cruise-Control Navigation (ICCN), which provides a natural and user-centered navigation method in virtual environment and can improve the reality and the presence. Intelligent Cruise-Control Navigation is composed of three major phases: Constant Velocity Navigation, Collision Detection and Avoidance, and Path Adjustment. The ICCN can reduce the user's fatigue and improve the user's presence and reality in the virtual environment. Through the experimental study it has been determined that the ICCN will be a natural, straightforward, and useful interface in VE.

In this study, we examined how the self-efficacies of North Korean defectors affect their adaptation to South Korean social culture. To this end, 209 North Korean defectors living in Seoul, Incheon, Wonju, or Ansan were surveyed. The results obtained showed shorter residence in South Korea and age were associated with greater fear of South Korean society and awareness of language and cultural differences. On the other hand, age and duration of residence were not found to affect relations between social adaptation and perceptions of low social status, discrimination, or prejudice by defectors, which suggests defectors often live in South Korea for a considerable time without overcoming perceptions of discrimination or prejudice. The factor that most influenced adaptation to social culture was self-efficacy, which affected not only socio-cultural adaptation but also self-sufficiency and the ability to promote oneself, which is essential for economic adaptation in South Korean society.

다시점 비디오는 여러 개의 시점(view-point)을 이용하여 현장감과 몰입감을 제공하는 새로운 형태의 멀티미디어 서비스이다. 시점의 개수가 증가함에 따라 방대한 양의 영상 데이터로 인한 영상 획득, 저장 전송 및 재현 시 문제가 발생한다. 또한 현재의 다시점 비디오에 관한 연구는 고정된 카메라로 환경이 제한되어 있다. 본 논문에서는 유동적인 카메라 환경에서 최적의 상관관계를 가지는 영상을 획득하기 위한 방법을 제안한다. 제안하는 방법은 영상의 일부분만을 선택하여 중복성을 먼저 측정하고, 중복성의 척도에 따라 사용자와의 상호작용을 통하여 높은 상관관계를 가지는 다시점 영상을 획득할 수 있다. 또한 영상 획득 시 카메라간의 조명 차이에 의해 발생되는 부정확성을 감소시키기 위해 영상 마스킹을 적용한다. 마스킹된 영상에 에지 검출 방법을 적용하여 변위 추정을 함으로써 계산 복잡도를 줄였다.
