최공집 圓光大學校 附設 體力科學硏究所 2002 體力科學硏究 Vol.25 No.2

The subjects of this study were sampled by using the Cluster Random Sampling with the population that consists of the 4th, 5th and 6th graders of elementary school and the 1st, 2nd and 3rd graders of middle school, who are currently training at Taekwondo training centers in Metropolitan City. The way to sample was made by randomly sampling 500 men and women from 30 Taekwondo training centers, which are registered at the Taekwondo Association of Kwangju Metropolitan City, and having a questionnaire survey with the method of self-assessment marking, that is, the direct interview method. Except 58 questionnaires that were judged to answer insincerely or had missing parts, 422 questionnaires were used for the actual analysis. The objective of this study is to research the trainees' satisfaction level about facility factors, analyze the contents, and thereby make the plan to activate Tae kwondo training centers, in order to effectively operate Taekwondo training centers. Thus, this study concluded as follows. First, it showed no significant in the comparison by gender and training period, and it showed the significant difference between 4th and 5th grader trainees of elementary school ~1st grader trainees of middle school and over 2nd grader trainees of middle school. Second, the satisfaction level of 4th grader ~1st grander trainees of middle school for facility factor was shown as high, whereas over the 2nd grader trainees of middle school low. Third, as for age, it showed the significant difference between the 10 year -old trainees, 11 year-old trainees ~14 year-old trainees and over 15 year-old trainees, and the satisfaction level of 10 year-old trainees for facility factors was shown as high, wheres over 15 year-old trainees low. Fourth, as for grade(Poom Geup), it showed the significant difference between the trainees with Geup grade and trainees with over Poom grade, and it showed the characteristic that the satisfaction level of the trainees with Geup grade for facility factors was high, whereas the trainees with over Poom grade low.

Saccharin의 展望性있는 化學的 製法과 副産物의 利用에 關한 硏究

柳珙植 群山大學校 1983 論文集 Vol.6 No.-

It seems very likely that the consumption of saccharin will be increased, according to the increasing national income and the variety of processed foodstuffs, with demand of carolieless foodstuffs for the prevention of supernutrition and diseases of adult people. Therefore all the nations in the world have been concentrated on developing artificial sweetstuffs substituting sugar for. As a result of it, the manufacturing process in the past was the one which used to solve O-toluene Sulfon Amid with 30% Sodium Hydroxide; this time the method is the one which is solved with definite diluted Sodium Hydroxide. This is why we want to reduce the poionous content as possible avoiding conc Alkaline Substances. Para-toluen Sulfo Chloride produced as by-product seems likely to be used as the followings: (1) the Ester, treated and manufactured with Alkaline Alchol, can be used as Alkalifing Reagent. (2) This Chloride can be used as Chlorifying Agent of Carbon Acid in Organic Synthesis. (3) this Chloride is used for the manufacture of Dialky1 Amine. (4) this Chloride is used for the manufacture of Chiramine T, Water disinfectant and Halazone. As the above, in order to keep our good health and to save foreign currency, we should not import the whole quantity of original crude sugar, but develop this area, by-products produced in the manufacture, and poisonless Saccharin in large quantity. Thus, if we export this in large quantity, taking the exclusive property of each market in the world, it is expected that this would contribute to economic development for exporting Korea.

界面活性濟의 化學的 特性과 應用에 關한 硏究

柳珙植 群山大學校自然科學硏究所 1986 自然科學硏究 Vol.1 No.-

I have investigated from surfactant to be used widely in daily life. 1. I have found a lot of special interesting things in which consists of Hydrophiles solution and oil. 2. I have reaffirmed to find out two kinds of type of dissociation which is done and not. It would be necessary to be capable of searching for the development of use in ion. 3. I have found the result in which surfactant could be applied in every field of utilities. Above all, emulsification has been functioned with a big important utilities. Above all, only the best way to choose suitable surface tention must be understood its function and utilities of it.

대기중 부유입자상물질의 통계적 해석에 관한 연구

강공언,신대윤 조선대학교 생산기술연구소 1992 生産技術硏究 Vol.14 No.2

In order to investigate the statistical analysis of ambient suspended particle at Seoul in Korea, airborne particulate matters were collected by High-Volume Air Sampler from April 1988 to May 1991, and size distribution of the aerosols were measured by filters on nine stages Andersen Air Sampler from January 1990 to December 1990. And with respect to seven components in the total suspended particulate, the factor analysis was performed. As a result of factor analysis by using the varimax rotation method, the chemical components in the TSP were able to characterize with two principal factors. The first factor (Factor 1) was considered to be a factor indicating the contribution of natural sources and the second factor(Factor 2) was a factor indicating the contribution of anthrophogenic sources. For concentration of size distribution measured by Andersen Air Sampler, tne factor analysis was also performed. As a result of factor analysis by using the varirnax rotation method, particle size distribution of atmospheric particulate was divided into two groups, coarse particle group was made by particles lager than 2.1㎛ in diameter and fine groups smaller than 1.1㎛ in diameter.

The results of this study on recreation and physical education are as follows : 1. It is necessary to develop technique and to cultivate taste of sports and plsy which can enjoy recreation as physical training. 2. It is necessary to make use of spare time and to build up view of value which rightful understanding and attitude on recreation. 3. It is necessary to create atmosphere in other that one may always apply recreation by completely furnishing physical facilities. 4. It is necessary to improve practical habit and capability which can assist physical training by making spare time fitting to aptitude. 5. It is necessary to emphasize importance of role in physical training as rightful recognition on recreation.

수학 모델을 이용한 체조 선수의 인체 분절의 관성 특성

尹恭和,朴宇奎 慶一大學校 1997 論文集 Vol.14 No.2

This study was conducted to determine the inertial charactristics of the body segment such as mass, mass center, and moments of inertia with respect to the three principal axes of rotation passing through the mass center of Korean male gymnasts using a mathematical model. The subjects chosen for this study were 7 male university gymnasts of 18-21 years of age. Two 35mm cameras enabled simultaneous photographs of the body to be made. The optical axes of the cameras were horizontally aligned to provide anterior and lateral views of the body. The photographic records were analyzed by reading the image using the scanner, defining the contours and required points of the segments using the mouse, and computing the inertial charactristics. The model of the human body described in this study was an advancement over previous mathematical models in that a representation of the segments by elliptical disc 5 mm wide followed the shape fluctuation of the body more closely. The accuracy of the method was evaluated by comparing the estimates of total body mass with the mass as measured on weigh scale. Table 2 provides the results of this study as mass, mass center, and moments of inertia of male gymnast body segment.

漱石作品における文體の變遷について : 「如し」を例として

羅工洙 全南大學校 人文科學硏究所 2001 용봉인문논총 Vol.30 No.-

근대 일본 소설의 거장인 나쓰메 소세키(夏目漱石)의 작품을 통해서 그 문체의 변화를 고찰하였다. 지금까지의 연구와는 다른 방법으로 「如し」를 통해서 고찰하였다. 그 내용을 정리하면 다음과 같다. ① 「如し」 와 「 樣だ」 의 사용률을 볼 경우, 초기작품에 비교적「如し」 의 비율이 높고, 후기작품으로 갈수록 점점 줄어든다. ② 「如し」의 활용을 볼 경우, 초기작품에 훈독문에서 많이 사용되는 종지형이 보이지만 후기 작품에는 사용되고 있지 않다. 그리고 동사 연용형과 접속할 경우, 훈독문에서 많이 사용되는 격조사 「が」 가 초기작품에 많이 있지만, 후기작품에는 사용되지 않는다. ③ 「みたやうだ」「みたいだ」를 볼 경우, 전 작품에서 「みたやうだ」가 보이지만, 후기작품에서 신 어법인「みたいだ」가 사용되고 있다. 이러한 결과가 나온 배경은 소세키는 어릴 적부터 한문을 배웠고, 기본적으로 한문의 소양이 깊었기 때문이다. 많은 한시를 남긴 것으로도 그 능력이 있음을 알 수 있다. 소세키는 작가활동을 타인보다 늦게 시작하여, 이미 언문일치의 확립.성립의 시기에 출발하였고 작가자신도 언문일치에 지대한 관심을 갖고 있었다. 그러나, 한문에 소양이 깊었던 소세키는 언문일치의 문장에 한문맥과 같은 문어적 표현을 써 넣고 있다. 그것이 특히 초기문장에 그 빈도가 높고, 후기작품에 갈수록 작아지는 것이다. 짧은 작가생활이었지만, 점점 구어화 할려고하는 움직임이 있었다.
