In these days, an open-door policy and the market economy of China have an effect on development of the all chinese society, and bring on changes in many fields- politics, economy, culture, and so on. Thus, the administative oganization of physical education on centralizing system based on existing planned economy system is changing. The system of the existing administative oganizationth of physical education is divided by the management system of government and community. The management system of government for administative oganization of physical education is still characteristic of centralizing system carried out main projects of physical education. There is many changes as result of system reformation to achieve the proper management system of administative oganization of physical education for the market economy. The management of centralizing system is weakened, and the self-control of the management system of community improve, that is, the macroscopic management funtion of government and microscopic management funtion of community is stregthened.

중소기업 전자상거래의 활성화전략에 관한 연구

조세형,김승철,정용균 한국중소기업학회 2004 中小企業硏究 Vol.26 No.2

전자상거래에 관한 대부분의 선행연구들은 기업의 전자상거래 채택 및 확산 요인에 초점을 두었으며, 대기업 중심의 자료를 바탕으로 연구가 수행되었다. 그러나, 기업에서의 전자 상거래 활용은 선택이 아닌 기정 사실화되었고 이제는 어떻게 활용하는가에 초점을 두어야할 때이다. 한편, 대기업을 대상으로 한 연구결과가 중소기업에 지침으로 제공되고 있으나, 중소기업이 단순히 대기업의 축소판이 아니며 많은 점에서 고유의 특성을 지니고 있기 때문에 중소기업 자체의 연구가 필요하다. 본 연구는 세 가지 측면에서 전자상거래에 환한 선행연구를 확장한다. 첫째는 많은 선행연구들이 주로 정보기술의 채택 및 확산이란 차원에서 전자상거래를 다루어 온 것에 비하여 본 연구에서는 전자상거래의 실행을 성과와 연관시켜 다룬다. 둘째는 국가경제에 커다란 비중을 차지하고 영향을 미치는 중소기업에 초점을 둔다. 끝으로, 중소기업에 적합한 전자상거래 활성화 전략을 제안하고자 한다. 연구결과 중소기업에 적합한 특유의 전자상거래 활용형태는 없으며, 기업상황에 적합한 활용형태를 찾는 것이 필요할 것으로 보인다. 한편, 정보시스템 성숙도 수준에 따라 IC실행형태가 성과에 미치는 영향에 차이가 있음을 발견하였다. 예를 들어, 비용우위 전략은 성숙도가 낮을수록 가치시스템형 IC는 성숙도가 높을수록 높은 성과를 나타냈다. Business firms are increasingly taking part in online business activities through internet as the size of the e-commerce market is rapidly growing in the recent years. Electronic commerce (EC) activities now become an essential part of the business strategy for survival as well as growth for both large enterprises and small- to medium-sized enterprises (SMEs). Previous studies on e-commerce mostly focused on the factors leading to adoption and diffusion of EC by business firms, and also have been carried out with the data from big enterprises. More often than not, the results obtained from the large business firms are used to provide the guidelines for SMEs. SMEs are, however, different from large business firms in many aspects, and need to be studied on their own. This paper extends the previous researches on EC in three aspects. Firstly, we study the e-commerce issues in the area of implementation in relation to EC performance, beyond the adoption and diffusion of IT technology which has been the research issues in many previous researches. Secondly, we focus on small and medium enterprises which comprise a large portion of national economy with significant influence. Finally, we propose desirable EC strategies for SMEs upon consideration of SMEs' characteristics.

The purpose of the present study is to determine the levels of maximal oxygen uptake and anaerobic threshold of boxing players(n=23), ken-do players(n=18), Judo players(n=12), T.D.K players(n=18). Treadmill test was used to measure maximal state and anaerobic threshold of metabolic variables. Treadmill exercises protocol was 2-min incremental test from an initial work load of 0MPH(grade : 0%) to all-out by step of 1.0MPH(grade : 2%). The results of measurement was as follows : 1. Absolute(1/min) and relative(ml/kg/min) maximal oxygen uptake was highest(5.08l/min, 65.01 ml/kg/min) in Judo layers, followed in order by the T.D.K players (4.37l/min, 64.74 ml/kg/min), Boxing players(4.18) l/min, 63.19 ml/kg/min) and ken-do players(3.81l/min, 58.65 ml/kg/min). It is not significant difference in the relative maximal oxygen uptake, but is significant difference between group in the absolute maximal oxygen uptake(p<0.001) 2. AT-VO₂(l/min) and AT-VO₂(ml/kg/min) in the anaerobic threshold was highest (3.71 l/min, 47.28 ml/kg/min) in Judo players, followed in order by the T.K.D players(3.29 l/min, 48.75 ml/kg/min), boxing players(2.90 l/min, 43.91 ml/kg/min) and ken-do players(2.82 l/min, 43.52 ml/kg/min). It is not significant difference in the AT-V02(ml/kg/min), but is significant difference between group in the AT-V02(l/min). (p<0.001) 3. %HRmax and %V 02max in the anaerobic threshold was not significant difference between group.

The t-test of dart throwing shows that there's no significant difference between the experimental group and the control group. However, Dan-jeon breathing group was higher than the control group in performing.

비대칭 Stilbene 유도체의 고체상 합성

조철희,류태용,박광용 한국공업화학회 2004 응용화학 Vol.8 No.2

Stilbene derivatives, which are of great interests due to their potent biological and optical activities (e.g. using emitting materials in OELD's and non-linear optical (NLO) materials), were produced via the nickel-catalyzed cross-coupling reactions of polymer-bound stilbenesulfonates with aryl Grignard reagents employing solid-phase organic synthesis (SPOS). This traceless method would be useful for preparing unfunctionalized arene library in solid-phase parallel synthesis.
