The purpose of this study is to introduce the elderly to a more active and suitable physical activity. Improvement in fitness parameters in old adults can oftern have a dramatic effect on the quality of life and maintenance of independance. It is necessary for them to understand the purpose of exercise and to encourage elder adults through the understanding of education in the progress of aging. The importance of physical activities as well as the suitable exercise method should be stressed in their everyday life. Present study suggests that there are some physical activities for elder adults to perform exercise, such as walking, swimming ans cycyling which does not much require stong power. Due to the physical abilities, it is vitai that these non weight bareing exercises are exteremely important. Also it is found that previous research recommanded this type of exercise according to age. Goverment and socity shoule provide facilities that are readily accessible to the older communities. Todays elder citizens must be provided with facilities that suitable equipment along with prefessional trainers and advises to this capabilities.

Factor affecting pollen and seed fertility were investigated for selfed progenies of trisomics and disomics added lead Rice chromosomes by chromosome engineering and F_1, F_2, and F_3 from the cross trisomics × Milyang^#23. They showed mostly over 70% of pollen fertility. Seed fertility was variable and its highest frequency distribution was below 10%, A F_3 plant showed 79.7% of seed fertility, indicating a potential of selection of breeding lines recovered economic characters. The first selfed progeny of trisomics and F_1 from the cross trisomics × Milyang^#23 showed mostly a nomal chromosome association at MI of PMCs. Sterility or low fertility of Lead Rice chromosome addition lines seemed to be not associated with chromosome aberration and sterile pollen grains.

This study intended to establish the change of children's socialistic attitude by T'aekwondo training of sex. Questionnaires containing 39 statements are administered to total of 400 students of privately owned T'aekwondo school in Pusan, Korea. Factor analysis, Cronbach's Alpha, and paired sample t-test is used to estimate relationship between each variables. These results were as follows; When socialistic attitude are compared for differences in the distinction of sex, mean scores differ significantly for the sex. A boy student was high the mean scores of all attitude variables but the introversive attitude. A girl student was only high the mean scores of the extroversive and the oriented careful concern attitude

With high school judo athletes as subjects, this study aims to reveal the relations between leadership types they favor and those they actually perceive. This analysis of the degrees of discrepancy and satisfaction felt by the athletes led to the following conclusions: 1.Leadership score according to sexes: 1) Autocratic behavior was the highest and affirmative feedback was the lowest in male teams. 2) Social support was the greatest and instructions appeared the lowest in female teams. 2.Leadership score in male teams according to team levels: 1) In superior teams, the highest and the lowest were social support and instructions respectively. 2) In inferior teams, autocratic and democratic behavior scored the highest and the lowest marks respectively. 3.Leadership score in female teams according to team levels: 1) In high-achievement teams, the highest and the lowest were social support and positive feedback respectively. 2) In low-achievement teams, autocratic behavior and instructions scored the highest and the lowest marks respectively. 4.Leadership discrepancy and athletes' satisfaction according to sexes: 1) The male group with lower discrepancy in instractions (p<0.01) and democratic behavior (p<0.001) showed greater satisfaction. 2) The female group with lower disagreement in autocratic behavior(p<0.01) indicated higher degrees of satisfaction. 5.Leadership behavior types and athletes' satisfaction degrees according to sexes and team levels: 1) In male teams, the excellent group in instructions and democratic behavior (p<0.01) revealed more satisfaction. 2) In female teams, the outstanding group in instructions (p<0.001), democratic behavior, and autocratic behavior (p<0.01) tuned out to be more satisfied.

가용성과 작업의 균등분배를 위한 JMX기반 클러스터 서버시스템

Information demands are fast rising, and today's computer system servers need to serve as many users and as many kinds of applications as possible, Therefore, a clustering system is mainly the internal structure of a server. Technically the server needs to be designed to load balance well. In this paper, a new clustering scheme is suggested for easy construction and maintenance of a server using Java Management Extensions. Recent Java technologies such as J2ME, J2EE, JMX, Jini and JDMK made it possible to integrate existing system functionalities based on the Java technology. Moreover, the adoption of application servers based on EJB technology speeds up rapidly. Recently, the demand of supporting on-line multimedia contents which have multiple terabytes size data increases. To address this problem, a clustering system which interconnects multiple computers with moderate price range seems to be very popular as an alternative to a single, high performance server. Experiments show that our system is easy to construct, expand, and load balance well even for dynamic situations of node additions, deletions, and malfunctions.

The purpose of this study was to investigate the changes of serum lipoprotein and apolipoprotein after 80min aerobic exercise. Subjects were composed of seven obese women. lipoprotein was determined for each subjects by administering a treadmill exercise test. The exercise intensities was 80%HRmax. The result of this study are as follows ; 1. Free fat acid was increased during walking exercise each 20min, 40min, 80min. 2. HDL-C was increased and LDL-C was decreased during walking exercise. Especially, more change at 80min. 3. Apo A-Ⅰ and Apo A-Ⅱ was significantly(p<.01) increased during walking exercise. 4. Apo C-Ⅱ was not changed, but Apo C-Ⅲ was decreased during walking exercise at 40min, 80min, In conclusion, bout walking exercise was shown to positive influence on serum lipoprotein and apolipoprotein. So it is maybe thought that walking exercise improved lipoprotein metabolism for obesity treatment.
