      • Strongyloides stercoralis의 Rhabditis form에 對한 硏究

        朴成均 대구보건대학 1995 대구보건대학 論文集 Vol.15 No.-

        In july 1990, I discovered rhabditis nematodes of two-cases from collected stool test at cooperation dressing room where is located in Taegu. Rhabditis nematodes isolated from their feces were cultured at 30℃ by a filter paper culture method. After careful observation of male and female adults, we confirmed them as Rhabditis elongata Schneider, 1866 on the morphological basis of the male genitalia, and the papillae and measurements of various parts of the worm bodies.

      • Palaemon nipponensis 內 Paragonimus westermani의 metacercaria로 因한 水汚染 調査 硏究

        朴成均 대구보건대학 1988 대구보건대학 論文集 Vol.11 No.-

        In this study the author observed the status of water contamination by Palaemon nipponensis, either alive or dead infected with Paragonimus westermani. The P. nipponensis used as materials were infected heavily with metacercaria of Paragonimus westermani. The live P. nipponensis were in water for a long time, and then the sediments of the water were examined to find out whether or not the liberation of the metacercaria from the body of the P. nipponensis had caused contamination of the water with metacercaria. Killed P. nippomensis were also preserved in water for some time, physical, stimuli in terms of moderate degree of shaking were added to the preserved water once a day and half amouut of the water was replaced with tapped water of same temperature everyday. Status of the decay of the P. nipponensis, liberation of the metacercaria from the boby of the P. nipponensis or contamination of the preserved water by the metacercaria, and numbers of metacercaria harboured in the body of the P. nipponensis were examined everyday. The fate of the metacercaria liberated from the P. nipponensis into water was also observed. The results of this study can be outlined as follows : 1)No metacercaria was detected in the water which contained live P. nipponensis infected with Paragonimus westermani. 2)The preserved water with dead or Killed P. nipponensis was found to be contaminated by the metacercaria of Paragonimus westermani, which had been caused by the decay and despersion of the flesh of the P. nipponensis. 3)The liberated metacercaria survived for 10 days in the water at 21∼27℃. 4)The liberated metacercatia were found to be sinking into water of s.q. 1,000 with velocity of 35.8㎝ per minute.

      • 벤덤의 政治思想에 관한 硏究

        朴成均 東亞大學校 大學院 1986 大學院論文集 Vol.11 No.-

        Nowadays England is trying to accomplish the welfare state with proiority given to par-liamentary democracy. We can not think this fact disregarding of historical transition of parliamentary democracy according to the change of English society. therefore we can find historical teachings through the consideration of the process of historical development up to the present time and in this sense it deserves special emphasis to study England historically today. In these days lively study of 19th century history of england is conngcted with these matters, because historical review is considered as important matters. This dissertation is only to analyse and view the political thought of Bentham, a utilitarian whose thoughts have an effect on the current of the times in the era of civil revolution with the process of industrial revolution, and it concerns about the historical background of his times. We designated Bentham as a great thinker. Because he developed the basic principles or conceptions in order to liberal reforms according to utilitarianism. And his thoughts are contained these matters such as law, politics, economics, education, education, social problems, international problems, religious problems, etc, which effected so widely. These were almost all the matters which modern states confronted at that time. Furthermore his greatness is to applicate these thoughts widely on the state which oriented modernity. Specially his principles which aims at democratic development of parliamentary government were very up-to-date at that time. Therefore this dissertation mainly considered the assertions about parliamentary reform which is based on the utilitarianism.

        In order to improve the mechanical properties and to utilize the useful properties of siloxane, -(AB) - type copolymers hove been the subject of study. The copolymers composed of siloxane(A) with functionalized end group as a soft segment and organic polymer(B) as a hard segment. In this study, -(AB) - type polysiloxane-polyurea copolymers were synthesized by reacting the g, m aminopropyl-terminated poly(1,1,1-kifluoropropylmethyl-dimethy1) siloxane as a soft segment and 4,4'-dicyclohexyl methane diisocyanate(H-MDI) and then 4,4'-methylenebis(cyclohexyl amice)Pl-DAM) as a hard segment in a mixed solvent system of THFINMP. It was found that there was THF/NMP mixture ratio to dissolve the copolymers according to the variations of siloxane content and F/O composition. The effects of the siloxane content, molecular weight, block length and the composition upon the mechanical properties were investigated. It was shown that the mechanical properties related to the degree of phase mixing of hard segment and soft segment.

      • 배추 파 무에 附着되어있는 寄生蟲卵 및 幼蟲의 調査

        朴成均 대구보건대학 1992 대구보건대학 論文集 Vol.13 No.-

        The high incidence of intestinal parasite eggs among the Korean people almost same as 40 years ago might be partly interpreted by the fact that they are all found of raw vegetables cultivatied on the farms fertilized with non-treated night soil. The cabbages, onions (scallion) and radishes were collected from the five areas of Taegu vicinity and the number of parasites attached to those vegetable were investigated to compare with the results obtained 10years ago by the same methods of sampling and examination as the present survey. The reaultant findings were summerized as follows : 1) The eggs of ascaris, hookworm, trichostrongylus and whipworm, rhabditoid larvae and filariform larvae of hookworms were detected from those vegetables. Additionally, a number of larvae of free living nematodes and morphologicaly undertermined eggs were also observed. 2) The maximum number of parasites found from one vegetable were as follows : 16 ascaris eggs on a cabbage, 27 hookworm eggs on an onion, 8 whipworm eggs on a cabbage, 68 filariform larvae of hookworm on an onion. 3) The onion were highly contaminated by the number of parsites as much as 177.6 including the larvae of free living nematodes, the next being the cabbages with 3 and the radishes with 4.1 in average. 4) No notable relationship was observed between the size of vegetables and the number of parasites attached to them. 5) Ascaris eggs were found from 56% of all cabbages, 28% of the Onions and 40% of the radishes : whipworm eggs were detected on 40% of radishes and the filariform larvae of hookworms were observed from 40% of onions examined. It may be concluded that there is un notable change in the number of of parasites attached to the vegetables coollected from the Taegu vicinity compared to the results investigated by the same method 10 years ago.
