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.

The purpose of this study was carried out an epidemiological survey on the prevalence rate of the canine heartworms in Seoul City and the districts of Pa-Ju, Seong-Nam and Po-Chon in Kyonggi province of Korea from September 1994 to the end of September 1995. The blood samples from 292 male and 193 female dogs (pet, 363 ; fighting dogs, 60 ; working dogs, 62) were examined for the adult heartworms cuticle antibodies using the enzyme-linked immunosorbent assay (ELSA) kits. The test was designed to detect the antibodies of the host against the specific cuticle antigens produced with the adult heartworms.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The status of facilities, management of the experiment, practices, and Science education teaching method in middle school have been investigated. The present status and reasonable management of middle school science education have been grasped from the questionaires. The results are as follows : The reasonable management for expeiments and practices of science education were scanty in the middle school around the urban and rural schools owing to the shortage of facilities and equipments, crowded class, excessive classes, work for teachers, excessive contents of present textbook and insufficience of administrative support etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper.
Cyclophosphamide가 Mouse 肝臟의 燐酸鹽 分解酵素 活性에 미치는 影響
강성준,이군자,정호삼,이규식 한양대학교 의과대학 1985 한양의대 학술지 Vol.5 No.2
Cyclophosphamide which is known as a widely used anticancer drug is very effective against a lymphosarcoma, leukemia and nonneoplasmic diseases such as rhematoid arthritis and lupus erythematosus. Cyclophosphamide acts on a DNA as a alkylating agent inhibiting the cell division and growth. And it is also known that metabolites of cyclophosphamide damages the liver cell. The authors have, therefore, undertaken to pursue the effect of cyclophosphamide on the phosphatase activity in the liver. Albino mice, DDY strain, weighing 20gm were used as experimental animals. The experimental animals were administered daily with 200gm of cyclophosphamide per kilogram of body weight were divided into 7-day treatment group and 10-day treatment group. The specimens obtained from the liver were fixed with 10% formalin and sliced at 16 μm thickness in a frozen cryostat. The activity of alkaline phosphatase was observed by the Gomori's method and activity of the adenosine triphosphatase was observed by the Wachstein-Meisel's method for histochemical study. The results were as follows. 1. Alkaline phosphatase activity of the hepatic lobule was moderately positive at the periportal and intermediate zone of the 7-day cyclophosphamide treatment group and trace activity of alkaline phosphatase was observed at the periportal and intermediate zone of the 10-day cyclophosphamide treatment group. 2. Adenosine triphosphatase activity of the hepatic lobule was moderately positive at the periportal, central and intermediate zone of the 7-day cyclophosphamide treatment group and weakly positive at the central and periportal zone of the 10-day cyclophosphamide treatment group.
