The purpose of this study was to investigate the effect of cooperative skill training on elementary school students' science achievement and self-esteem. Three different groups were used in this study. For the two treatment groups, cooperative loaming strategies were used and the one control group, traditional instruction was used. One of the treatment group was trained cooperative skills before the instruction. A total of 120 children sampled from 5th graders of a elementary school. All groups were taught about the change of the weather and structure of the plants. After the instruction a researcher made science achievement test and questionnaire of self-esteem were administered. The data analysis consisted of a 3(instructional strategies)×3(learning ability level) ANCOVA on the score of the achievement and self-esteem. The ANCOVA results revealed that there were significant main effect in the scores of achievement and also significant interaction effect between the instructional strategies and learning ability. The performance of high-level students in two treatment groups was higher than that of students in the control group, but the performance of high-level students with cooperative skill training was not higher than that of students without cooperative skill training. However, the performance of medium and low-level students with cooperative skill training was higher than that of students without cooperative skill training. The significant main effect was also found in the self-esteem but there were no significant interactions between the instructional strategies and learning ability. The academic self and social self of students with cooperative skill training was higher than that of students without cooperative skill training.

For the purpose of developing ‘Web-Based Nutritional Education Program’, this study did instructional analysis, analysis of entry behaviors and learner characteristics to select instructional contents for nutritional education program for junior/senior high school students. Survey questionnaires were distributed from October 21, 2002 to October 26, 2002 to a total of 564 junior/senior high school students in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. As a result of the curriculum analysis of ‘Technology-Home economics’, subjects related with ‘food and nutrition’ in the 7$^{th}$ educational course study result, lessons including the contents of food and nutrition were ‘nutrition and meal of adolescent’ in 7th grade, ‘family meal management’ in 9th grade and ‘practice of home life’ in 10th grade. According to the curriculum analysis, ‘nutrition’ and ‘food’ were chosen for the superior subjects of nutrition education program and four subordinate subjects per superior one were developed. Then, entry behaviors and learner characteristics were analyzed： life characteristics, internet usage, anthropometrics data and nutritional knowledge. Students were interested in using computer and preferred passive activity to dynamic activity. According. to the analysis of internet usage, WBI for students should composed active parts such as game, moving image, immediate reply and follow-up bye-mail, bulletin board and com- munity activity. Students’ BMI were in normal range but they were lacked nutritional knowledge. We wrote performance objectives that were specific behavior skills to be learned, the conditions under which they must be performed and the criteria for successful performance. The next step for developing the WBI nutrition education program would be based on the results mentioned above.

Purpose: Ineffective communication between healthcare professionals leads to medical errors and puts patients at risk of harm. The aim of this study was to examine the effects of interdisciplinary communication training in simulated settings on self-confidence in communication, observed communication behavior, and technical skill performances of nursing students. Methods: A repeated measures design with one group was conducted. Data was collected from 92 nursing students through a self-administered questionnaire and an observed behavior checklist. Data analysis was performed using descriptive statistics, a paired t-test, the Wilcoxon signed rank test, the Friedmann test, a Repeated Measures ANOVA, and the Spearman correlation coefficient. Results: Self-confidence in communication, observed Identification-Situation-Background-Assessment-Recommendation-Read Back communication behavior, and technical skill performances of nursing students were significantly improved. In observed communication behavior, the performance of Assessment and Read Back communication significantly improved. However, communication of Background, Assessment, and Recommendation did not improve to a satisfactory level. Observed communication behavior was not correlated with the overall technical skill performance. Conclusion: These results indicate that interdisciplinary communication training in simulated settings was effective in improving nursing students' confidence and communication skills with physicians. Longitudinal studies with larger samples are recommended in order to verify the effects of interdisciplinary communication training on clinical outcomes as well as communication competence.

The research was conducted to investigate the effect of drama education on the empathy and prosocial behavior abilities of middle school students. A total of 45 students participated in this study. Data were obtained through the use of the IRI(Interpersonal Reactivity Index) and the prosocial behavior scales. Those scales were administered to the group of students as a pre-test. Then, drama education was provided for 14 weeks for the group. The same scale was applied again to the group as a post test once the drama education was completed. The t-test on the differences between pre- and post test scores was used to analyze the effects of the program. The results showed that drama education had a statistically significant effect on the empathy and prosocial behavior abilities of students in the group. Finally, this study suggested implications for future performance arts education programs.

From the perspective that RPG games give players a sense of reality, the characterization of game characters can be said to be at the heart of design behavior. The personality of a unique character enhances the player's concern and commitment, allowing players to experience a variety of experiences. Through theoretical research and case analysis, this paper analyzes the expression of individuality in RPG game character design. In the RPG game, the way to express the character's individuality is first based on the game's time-space background, plot, task, etc. to inform the character's general gender, race, occupation, and skills. In line with the application and use of the characters, the roles will be developed in a concrete and rich way, and the shapes, movements, colors, costumes and weapons will be more refined. The purpose of this study is to obtain the main factors that influence RPG character's personality design from the viewpoint of perceptual design theory. In addition, it is proposed that the RPG game character personality design method should be adopted.

Extreme climate events can have a large impact on human life by hampering social, environmental, and economic development. Global circulation models (GCMs) are the widely used numerical models to understand the anticipated future climate change. However, different GCMs can project different future climates due to structural differences, varying initial boundary conditions and assumptions about the physical phenomena. The multi-model ensemble (MME) approach can improve the uncertainties associated with the different GCM outcomes. In this study, a comprehensive rating metric was used to select the best-performing GCMs out of 11 CMIP5 and 13 CMIP6 GCMs, according to their skills in terms of four temporal and five spatial performance indices, in replicating the 21 extreme climate indices during the baseline (1975-2017) in South Korea. The MME data were derived by averaging the simulations from all selected GCMs and three top-ranked GCMs. The random forest (RF) algorithm was also used to derive the MME data from the three top-ranked GCMs. The RF-derived MME data of the three top-ranked GCMs showed the highest performance in simulating the baseline extreme climate which was subsequently used to project the future extreme climate indices under both the representative concentration pathway (RCP) and the socioeconomic concentration pathway scenarios (SSP). The extreme cold and warming indices had declining and increasing trends, respectively, and most extreme precipitation indices had increasing trends over the period 2031-2100. Compared to all scenarios, RCP8.5 showed drastic changes in future extreme climate indices. The coasts in the east, south and west had stronger warming than the rest of the country, while mountain areas in the north experienced more extreme cold. While extreme cold climatology gradually declined from north to south, extreme warming climatology continuously grew from coastal to inland and northern mountainous regions. The results showed that the socially, environmentally and agriculturally important regions of South Korea were at increased risk of facing the detrimental impacts of extreme climatology.

Universities in Korea are presenting various extracurricular activities for survival and growth. Although the goals of extracurricular activities are diverse, one of the most important is to improve the academic achievement of college students. In this study, we looked at the relationship between the cumulative score of extracurricular activities by difficulty level and academic achievement. As a result, first, even if students' basic academic skills were controlled, extracurricular activities had a positive effect on student achievement. This suggests that universities should provide extracurricular activities that are more diverse and tailored to the needs of students. Second, the participation rate of female students in extracurricular activities is similar to that of male students, but the performance is very high. Third, Senior students show high levels of participation and performance. This means that it is necessary to actively increase the participation rate of female students and lower grade students. To this end, not only publicity and compensation, but also active interest and participation of instructors will be required.
