Ammonia 工業의 成長과 體質改善 및 展望에 관한 考察

柳珙植 群山大學校 1982 論文集 Vol.3 No.-

As I have referred to the prospect of Ammonia industry development and constitutional improvement up to now, Ammonia is considered not only the important material dirrctly connected with chemical industry but also one of basic materials for modern civilization. As a result of it, heneral conditions seem to grow up for the big development of this area industries in our nation, Ammonia has come to have further more connection not only with fertilizer but also our daily life as materials for petrolium chemical industry. And Ammonia industry has developed to have a great part on the nation's economic improvement. The advanced countries tend to dare to get rid of small scaled Ammonia plants of ages ago, and to try to bring up the new type process and enlarge the scale of factories. In the tendancy of Ammonia industry constitutional improvement all over the world we should finally come to use the higher priced Ammonia fertilizers and artificial fivers, etc., compared with the foreign manufactures because of the backwardness in the international competition, no matter how we carry out management rationlization and improve the industrial process in part with ready-made manufacturing systems and facilities. Therefore, it is considered that the major problem our nation has faced is that, in order to strengthen the international competitive force, we should manufacture artcles of Korean make, in low cost, made from Ammonium-materials by maunfacturing Ammonia in low cost through daring industrial constitutional improvement by way of not only bring in high technique according to the developing world Ammonia maunfacturing tendancy but also promoting plant-enlargement. Also, we must put our emphasis on developing an abudant electric power and manufacturing Hydrogenium in low cost using electrical analysis of water. In the viewpoint that our country is in want of natural resources and non-oil producing nation, Ammonia can be available for the basic materials, if we reserch and develope this area further more.

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.

This study aimed at examining how the organizational citizenship behavior as a significant attitude variable of organization members appear through daily sports activities and self-efficacy in local administration organizations. To study the organizational citizenship behavior of local public officers as an important attitude variable and the human resource management program that is used to guide their behaviors, it made an assumptive model based on the results of precedent studies and intended to examine its cause and effects. To achieve the purpose of the study, this study presented specific items to be examined and intended to identify them as follows. This study used questionnaire for the study, and it consists of questions about daily sports activities, self-efficacy, organizational citizenship behaviors, altruism, courtesy, sportsmanship, conscientiousness and civic virtue. The data, this study used the 'SPSSwin Ver. 10.01 statistics package' on a personal computer to perform descriptive statistics and demonstration of a research model and its assumption. For the statistical analysis, it used the single-dimensional analysis using Cronbach's Alpha, the Cross Tabulation, the Analysis of Variance (ANOVA) and the Multi-Regression.

유리섬유를 적층한 에폭시 수지의 충격특성에 관한 연구

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.

韓方藥의 藥理

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.

익산지역에서 자동 및 수동채취방식에 따른 강수의 화학적 특성 비교

강공언 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.3

In order to understand the precipitation acidity and chemical composition of ion species in Iksan area as well as to know the difference of chemical characteristics in precipitation samples from the viewpoint of precipitation sampling method, precipitation samples were collected by wet-only automatic precipitation sampler and hulk manual precipitation sampler in Iksan, from March 2003 to August 2003. The mean pH of precipitation was 5.0. There was a little significant difference in the mean value of pH between automatic and manual sampler. However, pH values of some precipitation samples were lower in automatic sampler than in manual sampler, especially in case of precipitation samples with small rainfall for March 2003. The mean concentrations of each ions in precipitation were generally a little higher in precipitation samples collected by the manual sampler than in those collected by the automatic sampler because of accumulation of dry deposition on the surface of glass funnel installed at the manual sampler during the sampling period of no rainfall. Dominant species determining the acidity of precipitation, were NH₄+ and nss-Ca^(2+) for cations and nss-SO₄^(2-) and NO₃- for anions. The mean concentration of NH₄+ and nss-Ca^(2+)j were 31 μeq/L and 9 μeq/L for the automatic sampler and 40 μeq/L and 16 μeq/L for the manual sampler, respectively. In addition, nss-SO₄^(2-) and NO₃- were 27 μeq/L and 13 μeq/L for the automatic sampler and 32 μeq/L and 17 μeq/L for the manual sampler, respectively. Although the concentrations of the acidifying ions of nss-SO₄^(2-) and NO₃- were about 3 times higher than those for foreign pristine sites, precipitation acidity were estimated to be natural due to the neutralization reaction of the alkaline species of NH₄+ and nss-Ca^(2+) with its higher concentrations. Considering the ratios of nss-SO₄^(2-)/NO₃- and NH₄+/nss-SO₄^(2-), it was found that ammonium sulphate was dominant in Iksan precipitation. The major non-sea salt ions were maximum concentrations for March, but decreased with increasing of precipitation amount.
