This study analyzes the content validity of descriptive tests developed for elementary schools, in order to acquire basic data to improve them. Various descriptive tests were collected and tested for differences in proportions between two-dimensional classification of educational objectives and the level of behavioral objectives. Results show that the descriptive tests developed by elementary school teachers mainly focused on "knowledge" and "understanding," and that content validity for behavioral levels to be low. Nine elementary school teachers were interviewed to understand the result. From the interviews, we found both internal and external factors that cause low content validity. The main internal factors were teachers' ability to make two-dimensional classification of educational objectives, the teachers' consideration of students' level, item level of difficulty, the ease of scoring, and path dependence. The main external factors were curriculum, parents, and administration. Based on the results, we suggested the factors related to elementary school teachers' PCK of descriptive tests.

Objectives: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. Methods: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. Results: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. Conclusions: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

전자상거래를 위한 인터넷의 웹사이트 구축 문제는 기업이나 조직의 중요한 새로운 마케팅 창구로서의 역할 때문에 그 중요성을 인식하고 효과적 디자인을 기반한 사이트구축이 이슈화 되었다. 그리하여 성공적인 인터넷 비즈니스를 위한 웹사이트의 구축 방법론이나 가이드라인의 연구가 필요하게 되며, 최근 소비자의 행동을 분석하여 이를 소비자 구매욕구를 증진시키는 방안으로 활용하여 전략적인 웹사이트를 구축하도록 제시하는 많은 연구들이 제시되고 있다. 그러나 전략적인 관점에서 웹사이트를 구축하거나 이미 구축된 웹사이트를 전략적 관점에서 개편하려고 할 때 사용될 수 있는 뚜렷한 방법론이 존재하지 않기 때문에 이런 관점의 분석모형이 절대적으로 필요한 실정이다. 이에 본 연구에서는 전략 형성과정에서 유용하게 사용될 수 있는 FCM(Fuzzy Cognitive Map)을 소개하고 이를 바탕으로 보다 구체적인 웹사이트 디자인 요소를 분석, 평가 할 수있는 방안을 제시하고자 한다. 본 논문에서 제시하는 FCM기반의 분석은 웹사이트의 성공요인들로 꼽히는 요인들간의 인과관계를 고려하여 웹사이트 구축의 요인간의 영향력의 민감도 분석을 할 수 있는 접근법으로서의 활용도가 기대된다.

The purpose of this study is to analyze the effect of art and culture experience according to art and culture perception on art and culture consumption. Accordingly, the perception expressed through the experiences of consumers was defined as the delivery of art and culture marketing strategies, and the behavior of consumers enjoying art and culture was measured. The research data were analyzed through an online survey. As a result of the analysis, sense, relation had a significant effect on the hedonistic factor, and the act, sense, emotion and relation had significant effects on the other's consciousness, and the behavioral and emotional factors had a significant effect on the intentional factors. The implication from the experience of relationships with others was found to have a negative(-) effect on all factors, which means to be the result of consumers' anxiety in enjoying art due to the pandemic. It is necessary to develop an online business model for consumers who naturally avoid it, and to narrow the gap between online and offline art and culture. Second, it is thought that sponsorship from companies is necessary so that artists who provide art and culture can produce high-quality contents. In the future, if it was studied the relationship between not only consumers who enjoy art and culture, but also suppliers and artists who provide art and culture, it will be able to understand the culture in-depth.

Objectives：This study was conducted to evaluate the effects of the attachment promotion program which was designed to promote attachment between autistic children and their mothers. The program was consisted of play activity centered mother-child interaction, educational activity for mothers by lecture, video-feedback session, and emotional supports. Methods：The subjects were consisted of 11 pairs of mother and child(7 for participant group：PG, 4 for non-participant group：NPG), who were 2-4 years-old autistic children. The data were collected by video-taping, behavioral observations, and analyzed by Wilcoxon Rank(Sign) Sum Test and Content Analysis. Results：The total attachment score increased from pre test to post-test of PG was significantly higher than that of NPG. The scores of attachment behaviors indicating proximity, mutuality and affect increased significantly(p<.05), while some behaviors indicating synchrony and jointattention did not. Especially the affectionate behaviors of PG demonstrated the most notable changes and they became more active, voluntary and reciprocal. After the program, the mother's nurturing behaviors of PG increased more than that of NPG, with no significant difference between two groups. The mother's behaviors to her child of PG became more child-centered, positively responsive, supportively expressive. As the attachment was promoted, there were also positive changes in the children's autistic behaviors with a great deal of individual differences. Conclusion：Our findings suggest that Mother-Child Attachment Promotion Program could be an effective early intervention model for autistic children.

Due to spread of movies or online games which are applied with computer animation techniques, we can easily see scenes where numerous characters appear. In the case of large-scale crowd animation, if one were to increase reality of the scene, features of system would be lowered, and if one were to increase functioning of system, reality of the scene would be lowered. In realizing large-scale crowd animation with seafloor environment as background, the paper analyzed and applied elements that affect behavioral types of fishes; and by using concept of crowd, the paper enabled each group or object to control their behavioral type; by comparing and contrasting real-time calculation method as calculation method for animation and hybrid calculation method which is mixed calculation method, the paper seeks to find a method that increases functioning of the system while also expresses natural scenes.

This study was conducted to prove the structural relation of how effective teaching methods in remote design courses affects learning participation and academic achievement. The data was acquired and analyzed with case study of design classes. The scale of remote practical classes, learning participation and academic achievement were measured and the data acquired were verified using SPSS and AMOS to prove the influence. The results are as follows. First, using the lecture method in remote classes appeared to have a negative effect on cognitive, emotional, and behavioral participation. Second, flipped learning had a positive effect on cognitive and emotional participation but no effect was found on behavioral participation. Third, PBL had a positive effect on all emotional, cognitive, and behavioral participation. Fourth, videos did not have any meaningful effect on cognitive and emotional participation but had a positive effect on behavioral participation. Fifth, only cognitive participation had a positive effect on academic achievement, but no relations were found between emotional and behavioral participation and academic achievement. These results suggest that it is needed combining actual classes with the PBL method and flipped learning and creating different programs.
