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.

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.

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.

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.

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.
