The research objective of this study to provide a basis for university basketball players development university basketball players have recovered and fair confidence in the result of the determination of analyzes feel the referee judges recognized research players and referees and by the referee judged that consistency there is. The referee judged according to gender awareness and the impact analysis of college basketball players impartiality, promptness, consistency, reliability p <.05 level There was a statistically significant difference. The referee judged recognition and impact of the exhibition was a statistically significant difference in the p <.05 level of agility. The referee judged recognition and influence of the position was no statistically significant difference in the p <.05 level of agility. impact of the judgment determining recognition fairness, promptness, there was a statistically significant difference in the p <.001 level of reliability. The referee judged of the psychological state is assigned prejudice, there was a statistically significant difference in the p <.001 level.

The purpose of the present study is to observe in-depth what kind of changes the establishment of a female basketball team in a college of education and the experiences the female basketball players have within that situation bring to their lives and their paths in life and social implications. To achieve this purpose, the female basketball team at the Department of Physical Education in P University was selected as a research environment and its members as research participants and qualitative research was conducted. Research results showed first, that female basketball athletes were already on a set path before they entered college. They had not thought about their path in life independently and had a passive attitude towards their life paths and were experiencing a culture in which studies were not permitted. Second, female basketball athletes discovered a new path upon college entrance. While meeting various friends, they gained friends and not just colleagues and after becoming aware that the main character in their lives is 'themselves', they showed autonomy. Based on this, factors for their change, which are the implications of this study, were first, the environment of P University's college of education which has strict regulations and a strong emphasis on academics when compared to other universities, second, the identity of being the first enrollments into the female basketball team of P University's college of education and the distinct characteristics of being a female athlete, third, the group's leader who contributed to their positively directed change. Ultimately, these factors served an important role in leading their change in the large frame of a university environment.

In this study, it was evaluated that the 3D tracking accuracy of basketball zone track line by real time GNSS satellite positioning methods which are VRS (Virtual Reference System), DGPS (Marine Differential GPS) and PP (Point Positioning) methods. The results of comparison between three methods over horizontal track of basketball zone, VRS, DGPS and PP methods showed ${\pm}$ several cm, ${\pm}$ m, and ${\pm}$ 2m horizontal position accuracy compared with real size respectively. And also, the grade and height deviation of the checking points on basketball zone by VRS method is very similar to the real grade and height, but results by DGPS and PP methods showed big variation and deviation in each case. We expected that VRS method using GNSS reference network will be a very useful tool compared with single based RTK method in real time accurate positioning such as precision construction fields, especially.

Methods for harvesting and storage of rice were also originally introduced from the ancient China like other practices of agricultural techniques. Thus, optimum time or rice harvesting was adopted by appropriate draining to prevent the losses, and efficient tools were utilized for harvesting and manufacturing. In addition, our unique and original techniques for rice storage were learned and handed down, which prevented winds and rains, and allowed good ventilation. In the 15th and 16th centuries, treatment of smartweed extracts as emphasized to prevent insect damage for stored barley and rice cutting immediately at harvest was encouraged to prevent shattering of rice grains. In the 18th and 19th centuries, means for prevention of damages by water, insects and rats when grains stored in the field were suggested. Also, studies for ecology of various rice cultivars and storage techniques for a long period of time were necessarily emphasized to assume the optimum time of harvest regionally and to cooperatively work timely.

본논문은 북해도대학심사학위논문으로 총면수 143면인 영문으로 되어 있고 도 48, 표 7, 문묵 66부도, 부표 20면이있음. Plow는 옛부터 발달한 농구이기 때문에 많은 연구가 행하여졌지만 복잡한 물리성을 가준 토양을 대상으로 하는 기계이기 때문에 미해결의 문제도 적지않다. 이견인저항에 대하여 토양의 종류 및 조건을 변경하면서 실제의 포장에서 조직적으로 행한 실험은 극히 적고, 하물며 우리나라의 쟁기에 관한 연구는 거의없다. 본논문은 쟁기의 특징을 구명하고, 그의 개량, 발달에 기여하기 위한 기기자료를 획득코저 실시한 것이다. 1. 쟁기와 플라우의 구조 및 그의 차이 특징을 명백히하고 이체에 걸리는 각종의 저항의 내용 또는 그 비율등에 대하여 과거의 연구성과를 소개하였다. 2. 발달사 ; 플라우는 B.C. 2000년경에 녹각, 목지의 인력용의 경운용구에서 발달하고, 동양이도 기원은 대체로 같고 발달과정이 다를 뿐이다. 쟁기는 양자강연안에 기원을 가진 지나이가 신라와 백제에 도입되여 차차 발달하고, 지역적인 특징을 가지게 되었다. 3. 본장은 쟁기의 견인력에 관한 이론적해석을하고, 쟁기의 진행에 의해 층상으로 전단되는 전단저항을 구하고 쟁기의 표면 및 지측판과 토양과의 마찰력, 그리고 토양의 이동의 관성력을 쟁기의 견인저항에 관련되는 주요한 "힘"으로 생각하고 진행방면, 수직방면의 힘의 성분의 평형을 고려하여 식 10. 12를 유도 하였다. 4. 본장에서는 실험계획, 방법 공시기, 공시포장등을 기록하고, 축력용의 쟁기와 플라우를 사용하여 전지 4종 답 2종의 포장에서 실험하는데 견인력계와 자동경심측정기를 사용하였다. 5. 실험결과 및 고찰; 경심과 견인저항 Dp와의 관계는 식 10. 12와 갈이 표시되고, 실제의 제치를 대입하여 이론식을 유도하였으니 직선에 가까운 관계가 있고, 실험결과는 조금 곡선에 가까워졌다. 그리고, 토양의 물리성이 견인력Dp에의 영향을 세밀히 검토하였다. 쟁기의 견인비저항에 있어서도 식 12에서 {{{{K=AT+ { B} over {T } +C}}}}로 표시할수 있기 때문에 최소치를 표시하는 경심이 존재하고 이값은 쟁기나 플라우폭의{{{{ { 1} over {2 } }}}} 즉 10m정도이고 쟁기는 비저항이 0.llkg/$\textrm{cm}^2$에서 0.39kg/$\textrm{cm}^2$이였다. 그러나 이 비저항도 토양의 물리성이 많은 영향을 미치고 있다. 6. 요약 및 결론 ; 이상의 장에서 검토 고찰한 결과만을 기재하고 플라우는 쟁기에 비해 견인저항 및 비저항이 논에서나 밭에서 대로 나타난 것이 특이하다. 이상의 내용을 지면관계로 3회에 거쳐 요약 발표합니다.
