The random amplified polymorphic DNAs (RAPD) technique was used to characterize seven isolates of the green seaweed Ulvales collected from Songjeng, Haeundae, Jumunjin, Dadaepo and Wando in Korea. Total DNA was extracted by the LiCI extraction method from thalli of green seaweed. The extracted DNA (3 ng) in 25 ㎕ reaction volume was amplified by 45 cycles of the polymerase chain reaction with arbitrary primers. Thirty-four primers resulted in 1227 PCR products ranged 240 bp to 1.5 kb of both conserved and polymorphic bands. Genetic similarities of the seven isolates calculated by Jaccard`s equation were ranged from 7% to 36%. Monostroma nitidum (Wando) was shown to be most distantly related with the others based on genetic similarity and did not produce the amplified band of 630 bp, common in Ulvales using primer OPB-01 (CATCCCCCTG).

The purpose of this study was to make a quantitative investigation into the impact of the leadership behavior style of Judo instructors on group cohesion and the satisfaction of group members in a bid to help determine what type of leadership style and profile Judo instructors should have. The subjects in this study were 278 players who were selected from a population that consisted of Judo players in Seoul and Gyeonggi province who joined Korea Judo Association. After a survey was conducted, the players who gave completed answer sheets were selected. The collected data were analyzed with SPSS PC+ Ver. 10.0 program in a way to serve the purpose of the study, and the findings of the study were as follows: First, there was a positive correlation between the leadership behavior style of Judo instructors and group cohesion. Regarding the impact of leadership behavior style on group cohesion, leadership behavior style exerted a positive influence at the 1% level of significance on social cohesion at a personal(training, social support and reward) and collective(authority, training, social support and reward) level, and on task cohesion at a personal(democracy, social support and reward) and collective(democracy and social support) level. Second, in terms of correlational relationship between the leadership behavior style of Judo instructors and the satisfaction of the group members, there was correlation among leadership behavior style, task reception and social interaction. The leadership behavior style had a positive impact at the 1% level of significance on their satisfaction with task reception (training and authority), social interaction(training and reward) and coach behaviors (training, democracy and reward). Third, as for the correlation of the extent of the workout of the Judo players to group cohesion and satisfaction, there was a positive correlation among their extent of exercise, satisfaction and coach behaviors. In regard to the influence of the extent of exercise on group cohesion, social cohesion at a personal level was under the influence of exercise hours and career at the 1% level of significance, and workout hours and career had a positive impact at the 1% level of significance on personal and group cohesion. Concerning the impact of the extent of workout on satisfaction, satisfaction with task reception was positively affected by workout hours at the 1% level of significance, and satisfaction with social interaction was positively influenced at the 1% level of significance by workout career and hours. Their satisfaction with coach behaviors was under the positive influence of workout hours at the 1% level of significance.

이 연구는 유도의 활성화 방안 모색을 역대 YMCA 유도를 토대로 하여 구체적으로 살펴보고자 한다. 이를 통해 한국유도의 정체성을 제시하여 하는데 논의 및 결론을 도출하였다. 이는 다음과 같이 확인할 수 있다. 첫째, 한국 YMCA 유도 발달사를 보면 YMCA가 유도를 시작한 연도를 명시(明示)하고 있는 사료는 없었다. 둘째, 1909년 YMCA가 도입한 유도에 관해서는 명확하지 않은 부분들이 많았다. 셋째, 서울YMCA는 1927년 6월 11일에 제1회 유도연무회를, 그리고 1928년 10월 13일에는 제2회 유도연무회를 개최하였다. 넷째, 1935년 제7회 대회를 마지막으로 중지되어 해방 후 다시 재개되었다. 다섯째, 1929년에 제1회 대회를 시작으로 현재 82회까지 열린 YMCA전국 유도대회의 각 연도별 우승팀을 확인할 수 있었다. 이와 같이 종합해 볼 때, 한국유도의 산재되어 있는 여러 가지 문제점을 파악하여 역대 YMCA 유도의 변천과정을 살펴보았다. 민족사상가의 역대 YMCA 유도의 역사에서 보이듯이 그 정책을 통해 한국유도의 활성화를 위한 방안 모색에 따른 정체성을 제시할 수 있는 것이다. This research is based on the generation of YMCA judo to grope a plan to activate judo. Through this it derived to a discussion and conclusion of Korea judo’s characteristics. This can be confirmed by the following. First, looking at the development of Korea YMCA judo, there wasn’t any clear statements about what year YMCA judo started. Second, there are unclear parts about judo that YMCA inducted in 1909. Third, Seoul YMCA opened the first judo military exercise on the 11th of June 1927 and the second on 13th October 1928. Fourth, the competition was stoped in 1935 but was reopened after release. Fifth, the first competition started in 1929 and presently there were 82 competitions, and it is able to check the winning team for the annual national YMCA judo competition. To look at all the above, to get hold of the problems that lies in Korea judo it able to look at the changes of YMCA judo, As seen as in the history of democratic judo, through the policy it is able to derive a characteristics of Korea judo’s plan to activate.

Water pollution in the lower reaches of the Namhan River is getting worse due to drought and a decrease in water quantity due to climatic changes and hence is affecting the water quality of Paldang Lake. Accordingly, we have used a water quality index (WQI) and statistical analysis in this study to identify the characteristics of the water quality in the lower reaches of the Namhan River, the main causes of water pollution, and tributaries that need priority management. Typically, 10 items (WT, pH, EC, DO, BOD, COD, SS, T-N, T-P, and TOC) were used as the water quality factors for the statistical analysis, and the matrix of data was set as 324 × 10·1. The correlation analysis demonstrated a strong correlation between Chemical Oxygen Demand (COD) and T-P with a high statistical significance (r=0.700, p<0.01). Furthermore, the result of principal component analysis (PCA) revealed that the main factors affecting the change in water quality were T-P and organic substances introduced into the water by rainfall. Based on the Mann-Kendall test, a statistically significant increase in pH was observed in SH-1, DL, SH-2, CM, and BH, along with an increase in WQI in SH-2 and SM. BH was identified as a tributary that needs priority management in the lower r eaches o f t he N amhan R iver, with a “ Somewhat p oor” ( IV) g rade i n T -P, “Fair” g rade i n WQI, and “Marginal” grade in summer.
