While most GIS are based on Euclidean space, cellular space can be used as an alternative type of space for a large number of GIS applications. In order to analyze the pattern of moving objects in cellular space, we need new definitions of similarity between their trajectories since the trajectory in cellular space significantly differs from those in Euclidean space. In this paper, we study the properties of moving objects in cellular space. Based on these observations, we propose several similarity measures between trajectories in cellular space. We analyze the difference of the proposed measures by experiments. 대부분의 지리정보 시스템들은 유클리디안 공간을 기반으로 하고 있지만, 셀룰러 공간 역시 많은 지리정보 시스템 응용을 위한 기반 공간으로 사용될 수 있다. 셀룰러 공간에 존재하는 이동객체의 이동 형태를 분석하기 위해서는, 유클리디안 공간과 분명히 다른 특징을 갖는 셀룰러 공간상에 존재하는 이동객체들의 유사도에 대한 새로운 정의가 필요하다. 본 논문에서는 셀룰러 공간에 존재하는 이동객체의 특성에 대해 살펴보았다. 이에 따라, 셀룰러 공간에 존재하는 궤적들 간의 유사도를 정의할 수 있는 2가지의 비교지수를 제시하고, 실험을 통해 제시한 비교 지수들 간의 차이를 분석하였다.

Purpose: The purpose of this study was to explore the relationships among workplace bullying, organizational commitment, and turnover intention of nurses. Methods: A cross-sectional study was conducted. Data were collected using a structured questionnaire from nurses at five public hospitals (N=190). Results: The experience of bullying was 31.29 points (range 16-64) on average: Work-related bullying was the highest, followed by verbal/non verbal bullying and external threats. The consequences of bullying were 30.54 points (range 13-52) on average: The physical/psychological withdrawal was the highest, followed by increasing distrust and the poor quality of patient care. The experiences of bullying had positive correlations with the consequences of bullying (r=.55, p<.001) and the turnover intention (r=.27, p<.001), and had a negative correlation with organizational commitment (r=-.28, p<.001). The consequences of bullying had a positive correlation with the turnover intention (r=.52, p<.001), and had a negative correlation with organizational commitment (r=-.49, p<.001). Organizational commitment showed a negative correlation with the turnover intention (r=.63, p<.001). Conclusion: The findings of this study suggests the needs of a regular monitoring system and organizational management for workplace bullying, which helps nurses to commit to their organization and to be retained in a workplace.

Purpose : The purpose of this study was to investigate drinking motives and the drinking-related problems of Korean high school students at a city in Jeonbuk province. Methods : There were 657 students from two academic and two vocational high schools at J city in Jeonbuk province. The sample was collected using a stratified sampling method and the data was collected from June 30th to July 16th 2003. The study instrument used to examine drinking motive was a 20.item summated scale (Cronbach's α = .95) and for drinking-related problems was an 18 item summated scale (Cronbach's α = .91). The data was analyzed using SPSS/PC+ by percentage, χ2.test, t-test and correlations. Results : 1. Drinking experience: Among the high school students, 74.3% of them had drinking episodes. Female students started drinking later (χ2 = 12.857, p = .002) and had more drinking friends (χ2 = 7.785, p = .020) than males. Vocational school students drank more frequently (χ2 = 32.138, p = .001), had more heavy drinking episodes (χ2 = 40.370, p = .001). 2. Drinking motives & Drinking-related problems: The mean score of drinking motives was 31.2 ± 11.12 out of 80 and that of drinking-related problems was 21.8 ± 5.85 out of 72 points. Neither score were stronger was significantly different according to gender and grade. On the other hand, both drinking motives (t = .4.077, p = .001) and drinking-related problems (t = .3.423, p = .001) were stronger in vocational school students than in academic school students. The correlation between drinking-related characteristics and problems were weak (from r = .286 to r = .520) but the correlation within the subcategories of drinking motives was high such as between enhancement and coping (r = .822) and enhancement and social motives (r = .822). Conclusion : The majority of Korean high school students start to drink during their junior high school days. Drinking motives and drinking-related problems were not serious but the drinking motives and the drinking-related problems are stronger among vocational school students. As a result, school-based health education and counseling programs should focus on solving drinking motives than on drinking-related problems.

Purpose: The purpose of this preliminary study was to investigate gender equality consciousness among elementary school teachers and the 6th graders at a rural area in Korea. Methods: There were 78 teachers and 323 6th graders from five elementary schools in Y area in Jeonnam province. The data was collected with a structured self-reported questionnaire from June to July 2003. The instrument, which was developed by Korean Women Development Institute to test gender equality consciousness, was composed of 20-items (Cronbach's α = .87 in teachr group; Cronbach's α = .83 in children group) with four subcategories: family life, school life, business life, and social life. The data was analyzed by a one-way ANOVA and t-test using SPSS/PC+. Results: 1. Teachers' gender equality consciousness: The teachers' gender equality consciousness was significantly more affirmative in females (t = 5.313, p = .001) and in the younger teacher group (F = 24.710, p = .001). On the other hand, there was no significant difference according to marital status. The differences in all four subcategories were also significantly affirmative in the female and younger teacher group. 2. Students' gender equality consciousness: The gender equality consciousness among the 6th graders was somewhat different from the teachers'. School girls (t = 8.988, p = .001) and children from double income families (t = 3.171, p = .042) were more affirmative in gender equality consciousness than the other groups. In the four sub-categories, school girls were also significantly more affirmative in all four subcategories. On the other hand, according to the family income source, the children from double income families also tended to be more affirmative only in the subcategory of family life (t = 3.196, p = .042) Conclusions: Gender equality consciousness is remarkably different according to gender both in Korean elementary school teachers and in school children. Age was a key variable in teachers for gender equality consciousness. Further research in gender equality consciousness of parents, school principals and urban school population would be useful. In order to promote gender equality consciousness, various educational materials and a mass education campaign should be developed.
