Purpose: To provide basic information for developing a nursing program by examining health risk behavior of students rewriting college entrance examinations. Method: Data were gathered using questionnaires from 804 examinees in Seoul and Gyeonggi Province and analyzed with the SAS program using t-test, ANOVA, Scheffe's test, and Pearson correlation coefficients. Results: The mean score for health risk behaviors was 17.70 and the highest score for sub-areas of health risk behavior was drinking alcohol while substance use ranked lowest. There were significantly different scores for health risk behavior according to the following general characteristics; frequency of rewriting college entrance examinations, parents' marital status, level of father's education, grades, satisfaction with rewriting of college entrance examinations, parents' health concerns, need for health education and health status. Each behavior had positive or negative correlation with more than one other behavior. A negative correlation was found between health risk behavior and family support and self-esteem, while positive correlations were found between health risk behavior and general stress, studying stress and anxiety. Conclusion: This study suggest that these results be used to developed a prevention program to decrease health risk behaviors by promoting family support and self esteem and decreasing stress and anxiety.

Purpose: In order to provide basic information for the development of nursing programs, health promoting behavior of students rewriting college entrance examinations was examined and factors related to health promotion were identified. Method: Data were collected by questionnaire from 804 examines in Seoul and Gyeonggi Province and were analyzed using the SAS program with t-test, ANOVA, Scheffe's test and Pearson correlation coefficients. Result: The mean score for health promoting behavior was 2.50. The highest score for the sub-areas was harmonious relationships and the lowest was, professional health maintenance. There were significant differences in health promoting behavior according to the following general characteristics; religion, frequency of rewriting college entrance examination, economic burden, parents' education level, grade, satisfaction with parents, friends and rewriting of college entrance examinations, parents' health concernsand knowledge of health, need for health education, and health condition and chronic disease over the past year. Correlations between health promoting behavior and family support and self-esteem were positive. The variables that influenced health promoting behavior were family support ($24.5\%$), self-esteem ($11.3\%$), anxiety ($2.6\%$), and stress of studying ($0.5\%$), explaining $38.9\%$ of the total variance. Conclusion: These results will help to develop a nursing program that enhances health promoting behavior of students rewriting college entrance examinations.

In traditional method, the establishment of database for current data of underground utilities would frequently occur a lot of losses in the time, economic effect and problems of accuracy because the procedure for the generations of transverse and vertical section mapping would be composed of many steps and the establishment of underground utility is inefficiently accomplished. The goals of this study are 1) to obtain digital information and data aquisition simultaneously by realtime in the field, 2) to develop the computer program of generation of transverse and vertical section mapping based on the plan for data transformation. As a result of this study, the establishment of database for underground utilities is able to save the time and improve economic effect and accuracy while minimizing errors in rewriting and acquiring data.

Flash memory becomes popular storage for small devices due to its efficiency, portability, low power consumption and large capacity. Unlike on hard disks, however, write operation on flash memory is much more expensive than read operation, so that it is critical for performance enhancement to reduce the number of executions of write operation. This paper proposes static analysis to rewrite a program to reduce the total number of write operations by merging writable data in a minimum number of pages. To achieve this, we collect information about writable areas by static analysis, and about frequently executed paths by profiling for practicality, and combine both to rewrite the application program to reallocate data. The performance enhancement gained from the proposed methods is shown using a FAST simulator.

This study is about the Novel Engineering(NE) education program : a class model that combines reading and engineering. By including the process of directly designing and programming a virtual reality using CospacesEdu (a VR authoring tool for the NE class), the effects of the educational program on learners' STEAM literacy and Learning immersion are demonstrated. Moreover, the subject of this education is Dokdo in South Korea. As a result, the average of STEAM literacy is increased, and a significant change is confirmed statistically in Convergence. Learning immersion shows significant improvement in Challenges-skills balance. On the other hand, some students experience difficulties due to the long research stages, from reading a book to researching for information to designing VR and rewriting a story with the collected information. In conclusion, this study will help generalise other education using NE, and this developed program will be a reference that would suggest a new way of teaching.
