食品公害에 대한 考察

We live in the age of various pollutions. One of them the food and drink pollutions are very grave and urgent for us. We often call this age the superior age of consumers. But the commercial morality has collapsed down in this country and it has worried the consumers constantly We can see the commodites of low quality and fraud goods are arranged in the shops, large or small, by fair means or foul. The cakes, drinks and food which contained and mixed with bacteria, poisonous elements and impurities not only have spoiled our body but also threatened our life. In this paper I have tried to examine and analyze the shapes, the ways of discrimination of bad or spoiled food and drinks. Besides, I have illustrated the poisonous elements which are contained in the bad or spoiled food and drinks and which are harmful to our body. It is urgent for the authorities concerned to lead and supervise the food and drink makers not to mix the harmful elements and moreover I suggest that they should take any powerful administrative or legal control or sanction to the evil food and drink makers and also should protect the people from the loss of health and life.

금강 하류의 기초생산성에 관한 연구 : 最長漲潮期(夏8~9月)의 염소도, 수온.PH, 영양염류 변동에 관한 연구 Study on the changes of chloronity, PH, water temperature, nutrient salts during the month at the greatest tidal cycle

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.

石灰石을 利用한 化學工業의 展望

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.

界面活性濟의 化學的 特性과 應用에 關한 硏究

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.

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.

In order to make a synthetic plan of complex organic compounds, first of all, it is necessary to be capable of searching for the objects' structures by each systematic thinking capacity and original ideas, accompanied by systematic synthesis. First, classifying of organic synthesis, 1. Total synthesis & partial synthesis 2. Rational synthesis & non-rational synthesis 3. Classified into linear synthesis and convergent synthesis Second, the synthesis of complex organic compounds 1. Finding out what is the important problem in synthetic process, the structure of the objects should be simplified by contrasting synthesis, and the important mid-materials and originals found. 2. Making several synthetic plans of them, comparing and examing the relative advantage and disadvantage(of them), making a decision of a specific synthetic plan, and selecting each procedure, specific reactions and reagents according to them should be chosen. 3. Planning and performing experiments, the result of them should be examined and analyzed, and the process to supplement insufficient parts added. 4. The rapid understanding of synthetic polymers requires full recongnation of the synthesis of complex organic compounds.
