류공식 군산대학교 1979 論文集 Vol.1 No.1
This paper is an attempt to survey and analyze copper contents in the sea-water of downstream of the GumRiver which empties into the Yellow sea holding contaminated water from the mining and metallic industries. To survey and analyze it, eight different areas of sea-water of the Gum River was picked up from the upper surfaces and the lower stratum at each full and ebb tides on April 20, 1978. Then careful examination in to the copper contents was made and the following results were obtained : 1. The sea-water of examining area of the downst rcam of the Gum River holds 0.048-0.141 parts per million (PPM) of copper contents, and the average is around 0.079 (PPM) 2. Copper contents at each full and ebb tides made some differences respectively. At ebb) tide copper contents (0.095) is rather heavier than that (0.063) at the full tide. It indicated that the sea-water comprised much copper contents. 3. It has been examined that the lower stratum (0.092) contains more copper contents than in the upper surface of the sea-water (0.067). 4. The result obtained after the examination by each area indicated that around Jang Hang Refinery, 1st area, the copper contents is heaviest (0.125) and the mouth of downstream of the Gum River, 3rd area, revealed the least amount (0.046) of copper contents. 5. Since the turbidity at the downstream of the Gum River is thick when seen through the naked eyes, the contamination seems to be serious, but it is thought that the pollution of the Gum River is not still sorious in terms of the quantity of copper, on of heavy metal, contained.

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.

尹恭和 慶一大學校 1999 論文集 Vol.16 No.4
The results of this study on juvenile problems and role of physical training are as follows. 1. It is necessary to build up emotional stability, law-abiding spirit, rightful view of value, and positive attitude of young people through activities of physical training. 2. It is necessary to provide comnunity that prootes cultured and balanced phyusical and spiritual health of young people through physical training. 3. It is necessary to grasp device of spare time in order that only young people who can be adapted to their lesson and spare time may personally have faith of success. 4. It is necessary to build active personality and to educate effective humanity which are trained through mind and body at the meaning of harmonized development of young people. 5. It is necessary to build spiritua power and sense of value that young people should fulfill responsibility and duty of group through physical training.

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.

金公朱,姜濚義 全北大學校 1988 論文集 Vol.30 No.-
Silk and wool are the two most important natural protein fibers. Because of there different Physical chemical properties the two fibers show quite different dyeability. In this study, we tride silk/wool blend fabric in one step using a one bath dyeing method. Acid dyes, 1 : 2 type metal complex dyes, and complex type reactive dyes used as the dyes. The results of the exsperiments can be summarized as follows
