The purpose of this study was to compare to the effects of regular exercise on body fat contents and plasma lipid composition of college women. This study was conducted from May to August in 2000. The subjects selected for the experiment were composed sixty three female college students. The basal anthropometric measurements were performed. The levels of total cholesterol, HDL-cholesterol, triglyceride and fatty acid composition of plasma were determined. And plasma glucose concentrations was also assayed. The results obtained are summerized as follows : Average height and weight of E(exercise) group were found to be slightly higher than NE(non exercise) group. The percent of body fat and body fat mass (kg) in E group was slightly lowered than that of NE group. There was decreased on the levels of plasma total cholesterol, triglyceride by regular exercise. HDL-cholesterol level was not significantly different between two groups, but LDL-cholesterol level in E group was significantly lowered than that of NE group. Therefore, plasma total cholesterol and LDL cholesterol levels was significantly decreased by regular exercise.

Clarifying differences of scholastic characteristics showed in male and female students is the first step for resolving the differences. It is difficult that we figure out them by one test. If we evaluate a few subjects, they can't have generality. So, we must evaluate lots of subjects through several years by all-around contents. We keep going on like that, we can get objective and valid results. Accordingly, I dealt with 2010~2014 NAEA taken by complete enumeration evaluation for elementary, middle, and high school students. From the evaluation, while I organized the achievement scores and the average of percentage of correct answers from aspects of whole test, item types, and content domains, I elicited from differences of scholastic characteristics showed in male and female students by achievement levels. On the basis of these, I explored ways which can resolve the differences in male and female students and I proposed several suggestions to look for the better ways.

As we enter the 21st century, interests in health and quality of life have grown gradually. In this study, we analyzed the data in response to each questionnaire for life management and sub-health among targeted members of a particular group. The results of the analysis of life management have found no difference between genders at the 5% of significance level. In respect to gender, a differential analysis of sub-health, however, has shown a gender difference in which female students had significantly worse health conditions than male students in the areas of immune system, intestine, cerebral nerve, hormone, and urinary system. Moreover, we also have found no significant difference among colleges in terms of life management and sub-health. In conclusion, it was shown that sub-health is closely related with life management.

This study wanted to see if there was a difference in the development of counselors before and after sandplay education analysis and verbal education analysis. Ten people were selected for the sandplay education analysis and the level of counselor development before and after receiving the verbal education analysis, divided into three groups that received the verbal education analysis, and the three groups that received the language education analysis. A nonparametric test, Kruskal-Wallis test, was conducted to identify differences in the results of the pre-parametric test, and a nonparametric test, Wilcoxon signed tank test was conducted to identify differences in the pre-post test results. Studies have shown that there is a statistically significant difference in the overall development of counselors and in case of case, in the whole of sandplay education analysis groups, while those that received verbal education analysis and those that did not receive education analysis do not have a statistically significant difference in the level of counselors development. This study is meaningful as it proves that sand play education analysis is effective in the development of counselors.

The purpose of this study was to find out the relations between elementary children's game addition, aggression, and personality, by making a survey with 360 children of 5th and 6th grade in the Metropolitan are. The results were made as follows: First, as it examined the real condition of computer addition, it presented a low level of addiction. There was a meaningful difference according to their gender, however no meaningful differences were found between the grades. It found that the more they had game experience, game frequency, game concentration, the more they were addicted. Second, there were significant differences when investigated the relations of game addiction and aggression, students who were in severe addicted group showed more aggressive attitudes. Aggression in general, seemed less related to the gender, but related to the level of addiction, showing higher level of physical, linguistic, negative, indirect aggression in the more addicted group. Third, when it compared the difference between the general personality by the level of game addiction, there was a meaningful difference statistically in the addicted level of p<0.01. In detail, more addicted children showed low level of sociality, achievement, mobility, stability, and they showed lower figures in comparison with normal user group. It is interpreted that they dislike to get along with friends, and unstable emotionally.

본 연구는 VO2max 70%의 고강도 유산소운동을 통해 각각 300kcal와 600kcal를 소비하는 시점에서 유발되는 면역세포 반응을 분석함으로써 운동량에 따라 어떠한 상이한 영향을 미치고, 인체 면역세포의 긍정적 변화와 면역력 강화를 위한 적정 칼로리 소비량을 구명하고자 남자 대학생 8명을 대상으로 면역반응 T cell(CD3), B cell(CD19), NK cell(CD16+CD56)을 SPSS Ver. 18.0 프로그램을 이용, one-way ANOVA, 사후검증은 Turkey HSD를 통해 분석한 결과, T cell(CD3)에서 운동전보다 운동량이 많아질수록 감소하였으며, 600kcal를 소비하였을때, 5% 수준에서 통계적으로 유의한 차이가 있는 것으로 나타났다. B cell(CD19)에서는 운동 전보다 운동량이 많을수록 감소하였으며, 유의한 차이는 보이지 않았다. NK cell(CD16+CD56)에서 운동 전보다 운동량이 많을수록 증가하였으며, 특히 600kcal를 소비하였을 때, 5% 수준에서 통계적으로 유의한 차이가 있는 것으로 나타났다.

멥쌀로 동진, 삼강을, 찹쌀로 신선, 한강품종을 선택하여 유과제조실험을 하였다. 사용한 멥쌀의 아밀로오스 함량은 각각 18.5%, 찹쌀은 2-3% 수준이었으며 수침시(12$^{\circ}C$) 2시간 이내에 평형 수분함량에 도달하였고 멥쌀은 30%, 찹쌀은 42%의 수화도를 보였다. 쌀전분의 호화 개시 온도는 64.5-67.5$^{\circ}C$로서 멥쌀과 찹쌀에서 큰 차이가 없었고 유과반데기는 RH 75-84%에서 저장하면 튀김 적정 수분함량인 11-12% 수준에서 유지 가능하였다. 멥쌀과 찹쌀로 유과를 제조, 비교한 결과 멥쌀의 팽화도는 2.5-2.9$m\ell$/g(건물), 찹쌀은 9.1-10.8$m\ell$/g(건물)로 멥쌀이 유의적으로 떨어지고 반대로 경도는 유의적으로 높아졌으며 바삭바삭한 정도는 차이를 보이지 않았다. 비정상 젖산 발효균에 의하여 팽화도, 경도 등은 개선되지 않았고 튀김 기름으로는 콩기름과 미강유간에 차이가 없었다.

본 연구는 H대학에서 비전공자 대상 교양필수 SW 교육과정을 프로그래밍 중심으로 개편한 2015년 이후 3개년도와 이전 3개 년도의 수업만족도에서 차이가 나는가에 대해 비교분석하여 개편 후 비전공자 대상 SW교육과정의 효과성을 파악하고자 한다. H대학은 2015년 교양 SW교육과정을 프로그래밍 중심으로 개편하였다. 개편 전후 수업 만족도의 변화가 있었는가? 라는 연구문제를 기반으로 분석한 결과, 개편 후 3년간 수업만족도는 개편 전 3년보다 높게 나타났으며, 1학기보다는 2학기 교과목들의 수업만족도 편차가 더 크게 나타났다. 1학기 만족도는 유의수준 10%에서 차이가 있는 것으로 나타났으며, 2학기 만족도는 유의수준 5%에서 차이가 있는 것으로 나타났다. 이것은 개편 후 다양한 프로그래밍 언어 중 선택할 수 있도록 교과과정을 제공한 것이 원인인 것으로 파악된다.

The aim of this study is to investigate the demographical differences in technostressors(cause technological stresses). Although previous studies have been conducted to investigate the factors that affect technostress, little studies have examined the differences in demographic factors. Therefore, this study empirically attempts to investigate how level of technostressors differ by demographic factors. Independent sample t-test was used to identify differences after dividing sample into two groups. The technostressors used in this work are work overload, life invasion, complexity of technology, job insecurity, pace of technological change. We found that, sex and position show a significant difference in pace of technological change. In the educational level, there is a difference between work overload. Work overload, life invasion, complexity of technology, and pace of change show differences in age group. In computer knowledge, there are differences in complexity technology, job insecurity, and pace of change. On the other hand, there is no difference in computer using hours. Conclusions and implications are discussed in final section.
