This study was performed to investigate the effects of sources and levels of dietary fiber on lipid metabolism in rats. Male weanling rats of Sprague-Dawley were fed ad libitum a diet containing perctin or cellulose at 5%, 10% and 20% for 4 weeks. Rats fed pectin gained significantly less weight than rats fed cellulose. Feed efficiency ratio was decreased at 10% and 20% group rats of pectin compared to control rats. Pectin was effective in lowering liver cholesterol, total lipid and triglyceride content at all levels. Whereas the cellulose supplementation had no effect to reduce serum and liver lipids. Cellulose led to an accumulation of serum and liver cholesterol. The least accumulation of lipid was in fed a cholesterol free diet. It is likely that lipid metabolism is quite different between pectin and cellulose feeding.

This study was to provide the basic information for the development of thermal weeder which uses LPG as fuel. Weed seeds of Digitaria sanguinalis S. and Portulaca oleracea L. mainly developed in fram and forestry nurseries were used as experimental samples. At different irradiation temperature(60, 80, 100, 150, $200^{\circ}C$), the dffects of weed seed species(digitalis, purslane), condition of seed(dry, soaked), and irradiation time(2, 5, 10, 20, 30, 60, 180, 300 sec) on seed viability were investigated was investigated by examining interaction and main effect of experimental factors. The results showed that viability of weed seed was significantly affected by all irradiation temperature tested. Irradiation time significantly affected on viability of weed seed on all levels of irradiation temperature. also, there were interactions between condition of weed seed and irradiation time on seed viability at each irradiation temperature.

The purpose of this research is to reveal the difference of teacher-child interaction in relation to professionalism awareness and sensitivity level of early childhood teachers. To this end, we used professionalism awareness, sensitivity, teacher-child interaction as parameters for 226 early childhood teachers in Jeonbuk province. Here are the results : First, we investigated the difference of professionalism awareness, sensitivity, teacher-child interaction in relation to the background of early childhood teachers, and it differs by the age, career, educational level of the teachers. Second, we made group comparison to see the difference of teacher-child interaction depending on professionalism awareness level of teachers, and teachers with high professionalism awareness showed meaningfully higher emotional, verbal, behavioral interaction level than lower group. Third, we made group comparison to see the difference of teacher-child interaction depending on sensitivity level, and teachers of high sensitivity shows meaningfully higher emotional, verbal interaction than lower group. This result could be potential data to ameliorate the quality of teacher-child interaction, and it implies that the improvement of professionalism and sensitivity level could contribute to professional performance capability of teachers.

In this study, the relationship between the organizational characteristics of police officers and the level of post-traumatic stress disorder in the comparative analysis was to check for post-traumatic stress disorder, according to the organizational characteristics affect. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. The department in post-traumatic stress disorder level, a significant difference was found. It was more likely to be exposed to a traumatic experience if who is working in the front-line department. Post-traumatic stress disorder according to the work unit, a significant difference was found. The level of Post-traumatic stress disorder in outside job unit officers was higher than that of desk job unit offcers. Post-traumatic stress disorder according to the rank and duration of employment and the administrative district level, a significant difference was not found.

본 연구에서는 이해능력수준에 따른 억압기제의 효율성 차이를 대용어 참조 과정을 통해 검증하였다. 실험 1에서는 단어재인과제를 사용하여 이해능력에 따른 가능한 참조어의 활성화 차이를 살펴 보았다. 그 결과 낮은 수준의 이해자는 높은 수준의 이해자에 비해 가능한 참조어 중 문장맥락에 맞는 적절한 참조어와 함께 맥락에 맞지 않는 부적절한 참조어의 활성화도 유지하고 있는 경향이 있었다. 실험 2에서는 검사단어의 맥락적절성 판단과제를 실시하였는데 낮은 수준의 이해자는 높은 수준의 이해자에 비해 부적절한 참조어를 부정하는데 반응시간이 오래 걸렸다. 이 결과들은 낮은 수준의 이해자가 덜 효율적인 억압기제를 가졌다는 가설을 지지하는 결과로 논의되었다.

This study analyzed the work and retirement behavior of middle- and old-aged Koreans using panel-data based multi-state life table models. Compared to previous studies that have mainly focused on gender differences in the work and retirement behavior, this study also analyzed educational differences in the retirement life course. With respect to the heterogeneity of work and retirement experiences, this study finds that the retirement life course of men and women differs substantially. Despite their longer life spans, women are expected to have shorter working life expectancies but live in a non-working state longer, resulting in a substantially higher proportion of non-working state in their lives. In terms of educational differences, this study finds that there is little difference in the expected length of stay in the labor force across educational levels but that poorly educated persons are more likely to spend a greater proportion of their lives in the labor force due to their shorter non-working life expectancies.

E-commerce has been developing rapidly by enabling companies to sell their products or services online. However, adoption of an e-commerce website still faces lots of problems, such as changing consumer behaviors from purchasing in physical stores to purchasing online, privacy and risk, and so on. The purpose of this study is to analyze the influence of consumers' attitude on actual purchasing behavior based on the degree of product information. In this study, we designed two kinds of product web pages which show different degrees of product information. The first web page has adequate product information, and the second one has much less product information than the first one. We found that according to degree of product information, there is a difference among perceived usefulness, privacy, attitude and actual behavior. And we also reveal weight difference between the two kinds of webpages. Finally, we indicated that variables have impact effect on both mutual relations and preceding relationships.
