石灰石을 利用한 化學工業의 展望

柳珙植 군산대학교 1980 論文集 Vol.1 No.-

As stated above, we can realize that 'Lime stone' is one of the most important resources which are able to hare a dirrect connection with organic and inorganic chemical industry. 'Lime stone' is gengraphically distributed on a large scale and its deposits arc not only inexhaust ible but also rather superior ill its quality. Therefore this Lime stone Industry is considered to involve the possibility enough to he developed, and the industrialization of 'Lime stonc' call be one of new ways out of difficulty in chemical industry field in Korea, none-oil producing country, suffering with scarcity of resources in general. The materials of chemical industry being 'Lime stone', how to develop and bring up our chemical industry --- that relys on how to produce abundant electric power in low cost. Saying again, the basic problem is that electric power producing in low cost is the only way to bring lip our chemical industry. Therefore if it is possible to produce electric power abundantly in low cost by developing all the rivers possible and build up water power plants it is believed that we are able to bring up this 'Lime stone' industry with it and produce the same products from 'Lime stone' as we get from the petrolium chemical Industry.

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.

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.

류공식,최상구,이화우 群山大學校基礎科學硏究所 1993 基礎科學硏究 Vol.8 No.-

에폭시 수지의 경화제와 경화조건을 변화시켜가며 유리섬유/에폭시 적층판의 충격특성을 연구하였다. 상온경화에서는 분자사슬이 긴 폴리아미드(G-1034)를 경화제로 사용했을 때 가장 큰 충격강도를 나타내었다. 가열경화에서는 파괴개시에너지가 상온경화에 비하여 높게 나타났으며, 후경화에서는 파괴 전파에너지가 높게 나타났다. 저온시험에서는 모재로부터 섬유의 이탈이 많이 일어난 것이 높은 충격 강도를 나타내었다. The influence of hardener and curing condition were studied on the impact properties of epoxy resin laminated with glass- fiber experimentally. Generally, the initiation energy of the epoxy composites was increased with heat - cure, and the propagation energy was also increased with post-cure. The total impact strength of composites cured with hardener of polyamide type was than that of aliphatic or aromatic amine type. The impact strength was increased with enhancement of propagation energy when it was tested at low temperature.

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.

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.
