Effects of panaxydol, panaxynol and panaxytriol isolated from Panax ginseng C.A. Meyer on some enzyme activities were determined. Activities of ATPase, membrane-bound enzyme from Sarcoma 180 and rat liver were slightly inhibited by panaxydol. Activities of 5'-nucleotidase, membrane-bound enzyme and succinate cytochrome c reductase in mitochonidria from sarcoma 180 and rat livers were significantly inhibited in a dose-dependent manner by panaxynol. The inhibitory effects of panaxydol and panaxynol on succinate cytochrome c reductase activities were more potent than those on 5'-nucleotidase activities and panaxynol was found to be a very potent inhibitor of succinate cytochrome c reductase. Activities of glucose-6-phosphatase in endoplasmic reticulum from Sarcoma 180 and rat livers were not affected by all three polyacetylenes. These results suggested that the inhibitory effects of panaxydol and panaxynol on enzyme activities might contribute to their biological activities.

The changes in activities of glyoxysomal and peroxisomal enzymes during the transition from fat degradation to photosynthesis were investigated with the cotyledns of rape (Brassica napus L.) seedlings. The development and disappearance of glyoxysomal enzyme (isocitrate lyase, EC 4.1.3.1; malate dehydrogenase, EC 1.1.1.37; catalase, EC 1.11.1.6) activities took place independently of light. It is concluded that the mobilization of storage fat is independent of photomorphogenesis. During early periods of development in the dark of light (days 1 through 3), the glyoxysomal enzyme activities were relatively high and the enzyme activities rose to a peak at 3rd day after sowing. Thereafter, the activities decreased gradually. While glyoxysomal enzyme activities were dropping, the peroxisomal enzyme (glycolate oxidase, EC 1.1.3.1) activities were increasing rapidly during the transition period in the light. Moreover, the changes of enzyme activities of the common microbody marker, catalase, indicated both functional patterns. The enzyme patterns in rape cotyledons indicate that the glyoxysomal function of microbodies is replaced by the peroxisomal function of these organelles during the transition from fat degradation to photosynthesis.

Objectives : The aims of this study were to evaluate changes in plasma superoxide dismutase(SOD) activities in alcohol depedence, to find out variables to influence on the SOD activities, and finally to identify the correlation of SOD activities with the alcohol-associated cognitive disorders. Methods : For 24 male alcoholics and 21 healthy male controls, plasma SOD activities were measured by spectrophotometry on 1-2 wks after alcohol withdrawal. Structured interviews and laboratory tests were also performed. Results : 1) Upon comparing SOD activities between controls and alcoholics, the SOD activities were significantly(p<0.01) lower in alcoholics($0.308{\pm}0.140$ units/mL) than in healthy controls($0.313{\pm}0.086$ units/mL). 2) Upon comparing SOD activities according to the presence of alcohol-related cognitive disorders, the SOD activities were significantly(p<0.05) lower in alcoholics with cognitive disorders($0.247{\pm}0.049$ units/mL) than in alcoholics without cognitive disorders($0.317{\pm}0.148$ units/mL). 3) Upon comparing SOD activities according to the presence of alcoholic polyneuropathy or alcohol withdrawal seizure, the SOD activities showed no significant differences between alcoholics with polyneuropathy or epilepsy and those without. 4) Upon analyzing variables influencing on the SOD activities in alcoholics, the SOD activities had the negative correlation with hemoglobin(${\gamma}=-0.433$) and severity of alcohol withdrawal symptoms(${\gamma}=-0.375$). 5) Upon comparing variables according to the presence of alcohol-related cognitive disorders, the occurrence of alcoholic polyneuropathy(p<0.05) and blood phosphorus concentrations(p<0.01) were significantly higher in alcoholics with cognitive disorders than those without. 6) Upon analyzing an association between SOD activities and variables in alcoholics with cognitive disorders, the SOD activities were positively correlated with the onset age(${\gamma}=0.995$), and negatively correlated with the severity of alcohol withdrawal symptoms(${\gamma}=-0.996$). Conclusions : Lower SOD activities in alcohol dependence suggested alcohol-associated cognitive disorders and alcohol withdrawal symptoms might be caused by oxidative stress.

This study examines the effects of adolescents' volunteer activities on their development of sense of community. When examining the effects of volunteer activities, both quantity and quality sides of volunteer activities were considered in the research model and besides the direct effects of volunteer activities on their sense of community, the mediating role of self-esteem and peer attachment were also examined. The data set of conducted by National Youth Policy Institute was reanalyzed for this study. The subjects of this study were 1,426 first-grade middle school students who had experiences of volunteer activities. The results of the study are as follows. First, the total hours of volunteer activities and the satisfaction with volunteer activities were positively related to their sense of community respectively. In an integrative model which combines both quantity and quality aspects of volunteer activities, however, only the satisfaction with volunteer activities was found to be significant. This means that the satisfaction with and reflective learning after volunteer activities are more important sides of adolescents' volunteer activities than whether and how many times they had experiences in volunteer activities. Second, the satisfaction with volunteer activities was found to enhance adolescents' self-esteem and peer attachment and the changes in their personal traits again led to a higher sense of community. Therefore, both the direct effects of volunteer activities and indirect effects through self-esteem and peer attachment were proved. Based on the results of the study, the need and ways to improve the management system of adolescents' volunteer activities were suggested.

This study determined the reality of how middle school students are doing with their free learning semester and what they think about it. Also, the study looked at how many parts of Home Economics and the area of clothing curriculum are being taken and, especially, how many parts of this curriculum content are being required as free learning semester activities. This study aims to not only develop free learning semester activities according to student demand but also at providing a basic resource that can help activate the area of clothing curriculum in subject of Home Economics. In short: 1) Middle school students are attending activities such as career exploration activities, student selection activities, club activities, arts activities and physical education activities thoroughly through the free learning semester. These mostly take place in school and most of the students were taught by teachers from their own school. 2) The students are aware that the free learning semester's activities are helpful for them. The most helpful part was that it reduces the load they get from the school's exam and also the fact that they can investigate areas in which they are interested. 3) The number of students who have already taken or are taking activities related to Home Economics were 145, which is about 1/3 of the 451 students overall. The area where the most of the activities were held out of those activities related to Home Economics was the domain of food while the clothing curriculum accounted for a very small part compared to it. 4) The study found that need for a clothing curriculum for middle school student free learning semesters was about 2.79 on a scale from 1 to 5. The areas of most interest in this topic were highly related to 'making and mending clothes'.

This study classified social stratum variables of adults in their 20s to 50s by subjective and objective measurements and classified leisure activities into groups to examine the conspicuous consumption of leisure apparel. A total of 365 adults in their 20s to 50s living in Daegu and the Kyungbuk area were selected considering their jobs and residences. SPSS PC+ 20.0 was used to analyze the data with frequency analysis, factor analysis, reliability examination, cluster analysis, ANOVA, Duncan-test, Scheffe-test, and ${\chi}^2-test$. The results of this study are shown as follows. First, 'Jogging/Walking' was found to be the most favorable activity in the examination of leisure sports activities among the participants and showed a difference in gender. Second, leisure activities were pastime-culture activity, sports activities, static activity, volunteering, and relaxing, and these activities were grouped into non-participant, active and passive leisure activities. Conspicuous consumption of leisure apparel was classified into personality oriented, luxury goods-oriented, and other people-oriented. Third, there was a significant difference in the sub-factors of the conspicuous consumption of leisure apparel (personality oriented, luxury goods-oriented, other people-oriented) according to the sub-factors of subjective stratum(economic power, social position, level of consumption, cultural level and overall stratum consciousness). Fourth, there was significance in the objective social stratum variable by the types of leisure activities. Significant differences were found in personality orientation, luxury goods-oriented, and other people-oriented in conspicuous consumption of leisure apparel by the types of leisure activities. Finally, there were significant differences in economic power, level of consumption, cultural level of subjective social stratum by gender, sports activities and volunteering in leisure activities, as well as other people-oriented conspicuous consumption of leisure apparel. This study also found significant differences in economic power, level of consumption and cultural level of social stratum by age, as well as other people-oriented conspicuous consumption of leisure apparel.
