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.

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.

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.

韓方藥의 藥理

김공수,유광석,한종현 圓光大學校 韓醫學硏究所 1993 원광한의학 Vol.3 No.1

Western medical science places the highest priority on scientific analysis and research. Therefore, Western medicine has obtained good results by estabilishing specific countermeasures against individual diseases, with causes thoroughly analysed and positively diagnosed. On the other hand, Oriental medical science has been particular about intergrating the part into the whole, in general. The superiority and/or inferiority of one approach over the other cannot be determined by either of the two medical sciences, due to the fundamentally different bases. Therefore, the two medical schools must now be combined, by distinguishing and isolating the respective characteristics in treatment, first seperatly and then combined, during a transition period. If Western medical science may be likened to a piece of brick, as its substance can be easily defined, Oriental medical science may be likened to cement. If one were to build a medical science house for the 21st century, a comfortable house could be built using either to the medical sciences as building material, Western medical science, corresponding to brick, or Oriental medical science, corresponding cement. Bricks are easily dimensioned and standardized, whereas cement is not only fixed in from, but requires a great deal of experience for its successful use. Howerever, both items are essential as building materials. It may be held that we can successfully treat the complicated pathogens of diseases afflicting the aged and chronically ill patients by making full and intelligent use of both medical sciences.

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.

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.
