Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

CdS thin film was fabricated by chemical bath deposition method and polycrystallined by the proper heat treatment. The physical properties of the amorphous and polycrystal of CdS thin film were observed and calculated by measuring the X-ray diffraction patterns, optical absorption, transmission and photoconductivity. From the present experiments, we obtained the energy band gap of the CdS polycrystal thin film to be 2.42eV and the In donor impurity level to be 0.025 eV below the conduction band : Another result was to be a_o=4.13Å and c_o=6.75Å for lattice constants of the hexagonal structure. Also, we attempted it to find the possibility of the application to photosensor. To apply cds this film to the photosensor more sufficiently, further experiments are required to accumulate data on such problems.

世界平和와 韓國의 役割

姜永晧,李瑛雨,金宇泰 경북대학교 법정대학 1976 法大論叢 Vol.14 No.-

World peace is an ideal which mankind has been searching for a long time. The League of Nations and the United Nations, established after World War Ⅰ and Ⅱ respecetively, were the results of the desire of peace-loving people attempting to solve international disputes and conflicts by peaceful means. Following the end of World War Ⅱ through 1950's the world has experienced a period of Cold War, replaced by an era of peaceful co-existence during 1960's. In 1970's the thaw in the struggle among big powers developed which further lessened the likelihood of war among the super powers. Taking advantage of improving international atmosphere, however, north Korean Communists have disguised themselves as the champion of peace and offered many so-called "peaceful unification formulas", thus misleading the world opinion. It is the objective of this paper to correct the misinformation concerning the problem of peace in Korea and to reveal true motive of the north Korean Communists by clarifying ROK's position on the issue of peaceful unification of the Korean Peninsula. Chapter Ⅰ is an introduction to this paper stating the problems and issues to be discussed in the paper. Chapter Ⅱ deals with putting Korean people's view of peace on the basis of the world peace by making clear the true idea of peace through historical development of peace theory in western history and searching the types of the world peace. Chapter Ⅲ is a study of peaceful nature of Korean people from the perspectives of Korean history. In order to make an effective analysis on above issue the Chapter is divided into three parts: first, a brief examination of the origin of Korean race; second, a study of Korean history based on mythology such as "Hong-Ik In-Gan" philosophy found in Dan-Gun myth and "So-Do" philosophy prevelant during the period of Three Hans; third, a historical recollection of numerous invasions of the Korean Peninsula by foreigners and yet the fact that at no time had Korea invaded its neighboring countries. Chapter Ⅳ deals with a period since the second World War, and particulary since the establishment of the Republic of Korea in 1948, in which the Korean Government, inheriting the spirit of peaceful nature of its people, has been pursuing peace. The Chapter is divided into two parts. The first deals with the period up to 1970 during which the R.O.K. was established (in 1948), the Korean War was erupted (in 1950), and the normalization of relations between Kore and Japan was achieved (in 1965). Internally, political stability and economic growth were realized in order to establish a firm base for an eventual peaceful unification of the Peninsula. Externally, this period saw the Republic of Korea expanding its diplomatic activities by establishing multilateral relationship with foreign countries. Since the beginning of the 1970's. President Park Chung Hee has universally published a series of epock-making plans to settle peace on the Korean Peninsula. President Park's August 15 Declaration (1970), a south-north joint communigue´ (1972), the declaration of a new foreign policy for peace and peaceful unification (1973), the proposal of non=aggression pact between the south and north (1974), and the proposal of three basic principles for peaceful unification (1974)-these are the expressions of the R.O.K.'s efforts to settle peace on the Peninsula and to contribute actively to the world peace. By studying the contribution of Korea to the world peace, it is hoped that the efforts by the Korean Government by clearly understood and this article would contribute in a small way toward the eventual unification of the Korean Penininsula.
