This study was surveyed to identify changes of flora during three years after restoration in Cheonggyecheon stream. There are four sections in Cheonggyecheon. One and two sections are upper streams and three and four sections are down streams. It was surveyed 328 species in 2006. In 2007 and 2008, 446 and 444 species were found, respectively. This result shows that Cheonggyecheon is unstable initial condition in restored stream ecosystem. Naturalized species were 58 species in 2006 and it was respectively 61 and 63 species in 2007 and 2008. Hazard species of ecosystem were three common species during survey period. In appearance of flora per section, three and four sections constituted by natural sites such as point bars, wide flood plains, riffles and ponds, marshes, etc. were surveyed more species than one and two constructed by concrete materials and narrow flow channel. Recently, as time goes by, introduced species are being increased. And succession has mainly been progressed by one year or binary herbs and perennial herbs.

Revised:8 December 2010. Accepted:20 December 2010. - 107 - Compared with other restored streams, Cheonggyecheon showed more flora than Yangjaecheon and Anyangcheon. It is judged owing to length of surveyed site, various planted species and area of inhabitation space. To manage restored stream ecosystem, monitoring is essential. Further, because change of vegetation after restoration in Cheonggyecheon is very important, continuous monitoring about Flora and Naturalized species and Hazard species of ecosystem is also very important.

The purpose of this study is an attempt to recognize the leadership style of athletics coaches and to provide effective coaching in the field. Leadership profiles of athletics coaches were analyzed to define the role of the competing value leadership that the leader in a athletics team exerts, and to know how the 6 roles of leadership influenced differently on athletics coaches according to characteristics of athletes. The subjects of this study are 23 male and 16 female athletes who are representative of national young age group. The differences of 6 roles of leadership profile were analyzed according to sex and event distinction. To provide a Z score for athletics coaches, each score of 6 roles of leadership profile were compared to other mean score of 34 individual events. The following conclusions were obtained from the results attained in these analyses : 1) The role of the analytic manager differs from sex distinction in leadership profile factors. 2) The role of the calculating executioner and innovative researcher differ between sprinters and long distance runners. 3) The role of the mentor differs between sprinters and throwers. 4) Male athletes and sprinters estimate coaches' leadership of their own as the role of the authoritative director. 5) The competing value of coaches leadership profile shows dynamics and productivity to long distance runners, throwers, and female athletes.

고추씨 기름 대체 향미유 개발에 관한 연구 : 치자, 고량을 이용한 유용성 천연 검정색소의 제조 Manufacturing of oil soluble natural black pigment from Gardenia and Kaoliang

치자로부터 청색 및 황색색소, 고량으로부터 암갈색 색소를 주정을 이용하여 추출·농축하여 60。Brix 농도의 추출물을 회수하였는데, 각각의 수율은 0.68, 1.97, 0.64% (w/w)였다. 이들을 대두유: 물: 유화제: 치자청: 치자황: 고량색소= 8: 22: 42: 10: 15: 13 (w/w)의 비율로 혼합하고 균질화하여 유용성 천연 검정색소를 얻었다. 이 색소를 대두유에 용해시킨 결과 대두유의 품온이 30∼40℃ 범위에서 가장 높은 용해도를 나타내었다. 대두유에 한 번 용해된 색소물질은 혼합 대두유의 품온을 20℃ 이하로 유지하여도 재분리현상이 발생하지 않는 것으로 확인되었다. Each pigments were obtained by ethyl alcohol extraction method, blue and yellow pigment from Gardenia as well as dark brown pigment from Kaoliang. Concentration of these pigments are all 60 Brix, the extraction yields were 0.68, 1.97, 0.63 %(w/w), respectively. Oil soluble natural black pigment (OSNBP) was composed of soybean oil, water, emulsifier, Gardenia blue and yellow, Kaoliang dark brown etc. Blending ration of these was 8: 22: 42: 10: 15: 13 (w/w), this mixture was carried out homogenized. Solubility of this OSNBP in soybean oil was appeared the maximum level at about 34~40℃ range. OSNBP solubilized black oil was not reseparated at below 20℃.

As a functions glass content and reaction conditions, the silver grain growth mechanism of Ag-bismuth-lead-borosilicate glass system thick film conductors were investigated. Grain growth mechanism of Ag varied with glass contents. When gless content was 2 wt.%, the grain growth mechanism of the silver was normal grain growth of solid state sintering. But in case of above 5 wt% glass in thick film conductor, silver grain growth mechanism was diffusion controlled Ostwald ripening of liquid phase sintering.

Sports is a subject of sociological study which directly and indirectly influences various dimension of society rather than a simple physical activity. Therefore this study is to achieve a scientific development of Sports Sociology and an establishment of its theory. 1) The subject of Sports Sociology can be definded to have two meanings. While one, the narrow meaning, deals with internal matters in Sports Group, the other, the broad meaing, deals with various problems in this present society. 2) Sports sociology should understand the general characteristics of present society and then explain the essence and function of Sports from various point of view. 3) Sports Sociology should play a role of human relationship formation in small group through face-to-face relationship which consequently advocate friendship among whole mankind. 4) Sports Sociology has been developped by characteristics of each society. The study tries to examine Sports in this present society rather than general sociality of Sports.

This paper presents a method to control the output voltage of QSRC using sliding mode control theory. State equation is derived for the system that introduced control theory is applied to equivalent circuit of QSRC. The parameter of control rule selected in order to minimize the effect of load variation. By proposed control method, it was shown that output voltage of QSRC was controlled continuously. Robustness of proposed controller was pointed out via computer simulation and experiment.
