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.

In order to study about the basic productivities on the estuary of the Kum River, first, I conducted several experiments on the tidal variation on the site encircled on Fig. 1. I measured PH, water temperature, outside temper ature, chloronity, nutrient salts. PH variation range was 7. 20-7. 95, water tempreature increased with outside one, chloronity varied from 1.0 to 13‰, NO2-N increase is proportional to part of fresh water flowed into the estuary and their range is 0.28-0.15㎍-aton/L. P04-P content increase is reversely proportional to fresh water content In general nutrient salts showed more higher value with water temperature increase. The results in detail of this experiment are shown up at Table 1, 2.
폴리 에틸렌 테레프탈레이트 섬유의 改質에 의한 染色性 改良에 關한 硏究

This paper concerns with the utilization of the treatment of sulfuric acid for improvement of dyeing of poly ethylene terephthalate(P. E. T) fiber. The P. E. T. fiber drafted to various times was treated with 70~74% sulfuric acid at 80~95℃ for 30~120min and neutralized with 2% ammonia. The fiber thus prepared has remarkable advantage in high yields of colours when dyed with C. I. Basic Green 4. The tensile strength of 3.2 times drafted P. E. T. fiber is as high as that of used fiber.

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.
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.
