大學體育의 基礎體力 評價基準 設定에 關한 硏究 : with reference to college physical education

최명종 명지대학교 1976 明大論文集 Vol.9 No.-

The primary purpose of the present study is to grasp the present level of basic physical fitness and execrise performance ability of college students who are at the stage of maturity in terms of mental and physical development, in order to establish evaluation standards of physical fitness by item and classify them by grade, thereby promoting the physical fitness of college students to above the middle grade. It is further intend to provide college physical education with a maxium effect by promoting the physical fitness of those belonging to the upper grade to the level that may enable them to participate in various tournaments through extracurricular activities of an athletic club according to their motor aptitude. 150 each of the freshman and sophomore male and female students enrolled in Myongji University in Seoul were sampled randomly and their physical fitness and exercise performance ability were measured in June, 1976. The test items used are as follows: (1) Height and weight (2) Standing with eyes closed (3) Grasping power (light and left) and back muscular strength (4) Trunk flexion (5) Trunk extension (6) Sit up (male, 6 sec.) (female, 30 sec.) (7) Vertical jump (8) Handball throwing (9) T.K. Cureton's Zig Zag Run (10) 100M dash (male) and 50M dash (female) (11) 1,500M run (mal) and H.C. Carlson's test (female) The average values of these items measured were compared analytically with local college students, all-Korea college students, Japanese college students, T.K. Cureton's and Japanese Manhood Standards to discuss their approprietness. The minimum and maximum limits of measurement values were divided into 20 grades and evaluation standards of physical fitness (Tables 15 and 16) were prepared aftero btaining T-Score against percentage. A decision chart was also prepared by grade by dividing into 5 stages according to the total score by each item. The results obtained as follows: 1. The physical fitness of college students in our country is generally in poor condition. Therefore it is felt absolutely necessary for those engaged in physical education to devote themselves to the promotion of physical fitness of all students to the upper grade of the evaluation standards proposed in this paper. 2. Systematic curicula of college physical education should be organized in such a way as to promote the physical fitness of all students. 3. The grade of physical fitness of those taking the lecture of physical education for cultural purpose should be determined on an annual basis and a system related directly to the credit of students should be introduced for those who fail to reach the grade as determined. 4. Based on the physical fitness evaluation standards promposed in this paper, it is felt necessary to collec tsamples as widely as possible and select those items which may be backed by scientific date or have reliability, objectivity, and propriety of test and to carry out studuies of this kind continuously in the future.

韓國과 日本 女學生의 [스포츠]에 대한 意識의 構造와 그 比較

This study was designed to compare the factorial structure sports of consciousness among female students in Korea and Japan, 134 students from Korea and 215 Japanese students enrolled in the Faculty of International Studies at Kyoritsu Women's University took part in the survey by completing a questionnaire consisting of 25 items. The results can be summarized as folldws: 1. From the results of the questionnarie it was concluded that 7 factors affected the sports consciouess of Korean students. It was interesting to note that 52.6% of the Korea students and 67.63% of the Japanese studentswere dispersed within the first three factors. 2. The item on the questionnarie were divided into 5 categories affecting sports consciousness. These categories were emotional, physical, social, volitional and behavioural. There were similarities between the two countries in the social and emotional categories. In the physical and behavioural categories, however, the degree of similarity was considerably lower. 3. Students from both countries were represented strongly in the factor relating to sociability, which suggested that both Korean and Japanese students were very concerned about the importance and significance of sport as a means of forming and maintaining friendships. The Korean students in particular tended to regard sports not only as a way to kept fit, but also as a way to encourage better communications, both among individuals and in society as a whole. 4. Korean and Japanese students thought similarly with regard to factors relating to beauty. It was also found, however, that in both countries there was a difference in consciousness between students studying gymastic and those studying for more academic qualifications. The former tended to be more concerned with trying to enhance their mental strength. while the latter were more interested in obtaining the 'ideal' female figure.

사각 고토오크 하이브리드 스텝모터의 설계 및 개발

정태경,최명종 중앙대학교 생산공학연구소 1994 생산공학연구소 논문집 Vol.3 No.1

Rectangular type hybrid step motor is designed to generate thirty percents higher torque than existing step motors. The torque for the motor is generated by the electromagnetic force at the air gap between the stator and rotor. The generating torque is proportioned to the rotor volume, i. e. rotor diameter. The main idea in this study is that the diameter of rotor is increased to generate more torque for the same overall motor size. This motors are manufactured by varying the shape of the teeth width of the stator and rotor. The optimum shape of the teeth is selected form the standpoint as smaller step angular accuracy.

자기저항법을 이용한 외전형 BLDC모터의 해석 및 설계

최명종,정태경 중앙대학교 생산공학연구소 1995 생산공학연구소 논문집 Vol.4 No.2

본 논문에서는 자기저항법에 의한 복사기 종이 이송용 외전형 BLDC 모터를 설계, 해석하였다. 본 논문은 자기 저항법을 이용하여 내전형 BLDC 모터의 거시적 해석을 시도 하던중 외전형 BLDG 모터에 대해서는 정립된 해석방법이나 설계방법이 빈약하다는 것을 알고 이를 규명하기위해 시작되었다. 수식의 특정적인 부분과 일반화된 부분을 다시 정리하여 내전형에서 뿐만아니라 외전형에서도 적절한 수식수정을 통한 적용이 가능함을 입증하고 있다. 본 연구의 진행방향은 내전형 BLDC 모터를 설계하는 수식을 이용해 자기 저항법으로 여러기기의 특성상 잘 맞지 않는 실험식을 수정하여 기기 마다 달라져야하는 해석의 요소를 규명하였다. 제조업체에서 제공한 데이터와 전술한 방법에 의한 해석을 비교하여 해석결과의 타당성을 비교, 검증하였고 이 값을 가지고 외전형 BLDC를 설계하였다. Outer-rotor type brushless dc motor is designed to run at more constant speed because of large inertia comparing with inner-rotor type. The constant speed is acquired by increasing inertia. Also, the generating torque is proportional to the rotor volume, i.e. rotor diameter. The main idea in this paper is to design and analyze the outer-rotor type brushless dc motor by permeance method with given outer dimension. By modifying the conventional formulas of dc motor inner-rotor type brushless dc motor we can provide a design and anaysis method of outer-rotor type brushless dc motor. And we prove its justness through computer simulation.
