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.

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.

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.

Spandex is man-made elastomer fiber. Chemically, polyurethane is produced by interaction of Glycol and Diisocyanate. From a physical point of view, these Spandex fibers owe their elasticity to the same thermodynamics as rubber, therefore, the high degree of fabric stretch availability permits its use in a wide range of textile fabrics. Particular interests are to improve the dyeing properties and to find out the dyeing mechanism. So, it is the purpose of this paper to present technology which will permit these yarn to be dyed with selected dyes and to describe the dyeing mechanism.

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.

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.

담화문법 관점에서의 지시대명사 celui와 celui-ci/la

김공대 한국 프랑스어문교육학회 1998 프랑스어문교육 Vol.6 No.-

Notre etude a pour objet les pronoms demonstratifs 'celui' et 'celui-ci/-la'. Nous entendons ainsi presenter des proprietes et des conditions syntaxiques des pronoms demonstratifs au point de vue de la grammaire du discours. Deuxiemement, nous voulons analyser les caracteres de l'endophoricites de 'celui' et 'celui-ci/-la'. Enfin, nous examinerons les rapports dont 1'information principale des cotextes du discours, par exemple, 1'information "active/ semi-active/ non-active' portent sur la relation de la reference. Les resultats principaux de 1'analyse de 'celui' au niveau de la grammaire du discours montrent premierement que 'celui' doit anaphoriser tout 1'ensemble du GN employe comme objet direct. Deuxierement, 'celui' doit anaphoriser le GN en tenant compte du genre et du nombre pour 1'accord de 1'anaphoricite. Troisiemement, 'celui+relative' peut etre employe pour eviter une ambiguite si nous voulons choisir 1'un des candidats-antecedents. Les resultats de 'celui-ci/-la' au niveau de la grammaire du discours sont les suivants : 1. Pour que 'celui-la' s'emploie comme attribut, le pronom interrogatif 'qui' doit contenir 1'information interrogative sur la personne en focus, et le pronom interrogatif 'lequel' le processus de 1'abstraction ou du choix. 2. 'Celui-ci/-la'ne maintiennent plus 1'anaphoricite avec les noms non-defenis. 3. Selon le resultat de 1'examen qui s'attache a la possibilite de remplacer des formes a 1'indice simple 'celui' par des formes a double indice 'celui-ci/-la', seule la phrase contenant un attribut voit cette possibilite reelle a condition que 1'attribut puisse se deplacer. 4. Il est possible d'operer un detachement a droite si 'celui-ci' anaphorise le GN a la fin de la phrase. Dans le cas de 'celui-la', si 'celui-la' anaphorise les pronoms 'il(s)' nous pouvons operer un detachement a droite. 5. Si le refere vise est [-Humain] 1'accord du genre est obligatoire; en revanche, s'il est [+Humain], 1'accord du genre ne 1'est pas. 6. 'Celui-la' anaphorise sans difficulte le GN, sujet, place au debut de la phrase; mais 'celui-ci' anaphorise le GN, objet direct, place a la fin de la phrase. Les resultats principaux de l'endophoricite de 'celui' et de 'celui-ci/-la' sont les suivants: (1) 'Celui' et 'celui-ci/-la' reclassifient les referes, surtout 'celui-la' prend le role le plus actif. 'Celui-la' montre son endophoricite par une relation de derivation (ex:31,32), de 1'hyperonyme/hyponyme' (ex:33,34), de 1'expression du sentiment (ex.35) et de la personnification (ex:36-38). 'Celle-la' montre son endophoricite par une relation de resume (ex:39,40) pour designer un fait ou un dit avec le sens de 'cette action' ou 'cette histoire'. (2) Ils fonctionnent par le contraste de la notion interne. 'Celui-ci' a le contraste, interne avec le GN determine par 'autre', pourtant 'celui-la' contraste non seulement avec le GN determine par 'autre', mais aussi avec le GN detache au debut ou a la fin de la phrase. (3). Ils identifient 1'antecedent avec la forme monolithique ou 1'appariement. En ce sens, 'celui-ci' anaphorise le plus proche, et 'celui-la' le plus eloigne, des deux candidats-antecedents.
