金柄斗,蔡鴻遠,安禹洪,李敏炯,申榮吉,金基學,鄭相澤,林銖遠 慶北大學校 體育科學硏究所 1987 체육과학연구지 Vol.3 No.-

The purpose of this paper is to investigate and analyze the nation's consciousness about the social physical education by regional groups(big cityes, middle cityes, farm village, fishing villge). And the researchers are to find a way to populize this movement. These subjects for this investigation were chosen at random among the citizens in four region. 4,450 sheets of questionnaire were given to the citizen. And 3,587(81%) sheets of them were received from male(2,582) and female(975) citizens. The results of this investigation are as follows: 1. The nation's consciousness has not been still modernized and the nation tend to depend on their doctors rather than on the new active leisure sports, which is a passive and conventional way, to keep their health. 2. Most people have spent their leisures on nonactive hobby such as reading, listening to music, and watching TV rather than sports. 3. Most residents pointed out lack of facilities, and needed professional directors and various programs they could participate. 4. The opening of citizen athletic field and the gymnasiums to citizens was needed to recruit the lack of facility, and the participation to commercial sport ws differed by economical status and leisure time, however, they usually participated such activities as table-tennis, swimning and tennis. 5. To activate social physical education, first of all, an expansion of the facilities such as athletic fields and gymnasium is needed under the active support of government. 6. The facilities for young men and the handicapped is insufficient, and to prevent juvenile delinquency and guide them into the right way, we should lead them out to participate sports activity. And the facility for the handicapped is needed too.

金基學,李淳川 慶北大學校 師範大學 1978 敎育硏究誌 Vol.20 No.-

The investigation and analysis of ideal shooting angle, region and form in the basketball games of high school and college team, shows the following result. 1. The success of field throw in Angle and Region according to each position; The success of field throw in a angle according to each position made no difference in angle "A", "B" and "C" with High School team as well as with College team, except that, as for center position, it marked 45.9% at angle "A" and 21.3% angle "C". From the regional standpoint, as for the position of the high school team, it marked 70% in the inner field(restricted area), 30% in the outer field at angle "C", and 71.79% in the inner field, 28.21% in the outer field at angle "B". As for Guard position it made no. difference between inner and outer field in the high school team, but in the college team it marked 85.96% in the inner field, 14.04% in the outer field at angle "C". As for center position, the frequency of success in field throw was higher in the inner field than in the outer field except the case of field throw at angle "C" in the college team. As a result, the frequency of success in field throw makes no difference in angle, but from the regional standpoint, it is higher in the restricted area. 2. Field throw Form according to each position; Both in high school and in college team, Jumpshoot is the main form of making goals and the frequency of success marked 66.23% in Forward positions 69.68% in Guard position and 71.28% in Center position. But ifs particular that the player in Forward or Guard position made goals by means of Lay up shoot as his secondary form of shooting; the player in Center position by means of pivot or turn shoot. The frequency of success as a secondary form of shooting marked 14.29% in Forward position, 16.29% in Guard position and 20.21% in Center position. 3. The Frequency of Success in field throw according to each position; Both in high school and in college team, the success in field throw rates the highest in Forward position, the higher in Guard, and the lowest in Center. But in high school team, the success frequency in Guard position, which is similiar to that in Forward position, is higher and in college team it is lower as in the case of Center position. As a conclusion it is supposed that we should develop the technique of shooting, the last goal of basketball game, with reference to the result mentioned above.

男子 大學生의 體力 Test Battery에 關한 硏究

金基學 慶北大學校 1990 論文集 Vol.49 No.-

The purpose of this study was to develope a test battery and evaluation scales for measuring the physical fitness of male college students. 125 male college students, aged 18 to 20, participated as subjects and were administered 20 test items. After the test, estimation equation of factors and evaluation scales for both factor and ability were devised by extraction and interpretation of the factors through factor analysis. The conclusions obtained from this study were as follows: 1. Physical fitness of male college students were composed of 8 factors including explosive strength, speed of changing direction, speed of movement completion, static strength, static balance, static flexibility, muscular endurance, and cardiorespiratory endurance. 2. To measure the interpreted factor, an estimation equation of factors made of standard score was determind, and, by inserting the statistics(mean and standard deviation) of each variable, it was translated into an equation which calculate factor score by using of raw score. 3. A test battery was developed in considering factor loading, reliability, validity, and practicability for each factor. Test items included in the test battery were vertical jump, boomerang run, completion time(back), grip strength, squat thrust, stork stand, trunk extension, and 1500m fast walk. 4. Evaluation scales with 5 grades for both factor and ability were developed to evaluate the test battrry. 5. To develope an estimation scale for ability, mean and standard deviation for each 8 item was divided into 11 grades(from 0 to 10) by C-scale. A perfect score for the test was 80 points. The total score was obtained by applying the raw scores of individuals to this score table. On the basis of the statistics of the obtained total score, the evaluation scale with 5 grades(A,B,C,D, and E) was devised to interpret test scores. ◁표 삽입▷(원문을 참조하세요)

運動能力의 因子分析的 硏究의 史的 考察

金基學 慶北大學校 體育科學硏究所 1989 체육과학연구지 Vol.5 No.-

Many studies have been done employing factor analysis,since McCloy, C. H. extracted three factors, i. e. strength, velocity, and coordination, by applying multiple factor solution to motor capacity test battery in 1934. The investigations, studied from the 1930's to 1984, were examined in this study, with the classification of 1) factor solution applied to the factor analysis studies of the motor ability, 2) extracted factors, 3) periodical characteristics, and 4) sex differences. 112 studies were referred, and they could be summarized as follows. The studies discussing the structures of the motor ability in the factor analytic points of view, can be divided into three models, i. e. applying (1) multiple factors, (2) general factors and group factors, and (3) hierarchical factors. Most of the investigations published in America, applied multiple factor model, and Highmore, an Englishman, employed a model applyihg general factors and group factors. However, Matsuura, Inoue, and Nakamura et al., Japanese, suggested a structure of muscular strength and motor ability employing hierarchical factor model. The current trend in the studies on the factor structure of motor ability is to validate the validity and objectivity of the factors and induce a conclusion about factor structures by exrtacting a Robust factor. The Robust factor is extracted in the examination of the rotated factor pattern matrix obtained by several solutions. The solutions commonly applied are Principal component analysis, Principal factor solution, Image factor solution, Canonical factor solution, Alpha factor solution, Maximum likelihood factor solution, etc.. Considering the extracted factors in the domains of strength, agility, coordination, balance, flexibility, endurance, and physique, the factor on the muscular strength was induced most frequently, which suggests that the muscular strength be the most important factor in the motor ability and physical fitness. In addition, muscular strength domain was divided into static, dynamic and explosive strength, and muscular endurance, and induced again as various differentiated factor. With regards to periodical characteristics, the factor analysis studies of the motor ability, begun in the 1930's, have been continued to the 1980's, and the application ranges have been changed from the investigations of the overall motor abilities to the examinations of the individual factors. The investigations on the sex differences of motor ability have been progressed from the comparative studies of fitness for performance to the examination of the sex differences of the factor structures. This part, in particular, escaped from simple comparative studies of the factor structures, have a tendency of applying a comparative study method based on communality of factor pattern matrix, factor similarity, correspondence to the hypothesized factor, simpleness of the factor interpretation, simple structures of the factors, etc..
