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.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

Studies were conducted to investigate the response of some horticultural plants to various light qualities provided by different kind of materials such as cellophane sheets, EVA, PVC(polyvinyl chloride,. and polyethylene (FE) films of different color. Major findings are summarized as follows. White fluorescence light and red light promoted seed germination of lettuce and inhibited that of radish seeds. Blue light inhibited the seed germination of both types of light-sensitive seeds. The light sensitivity varied considerably depending upon the kind of crops, cultivars, and the seed batches of the same cultivar. The blue light was equally or more strongly effective in inhibiting the seed germination as compared to the farred light. The growth of young seedlings developed from seeds was considerably promoted when grown under orange colored plastic film coverings The growth of larger seedlings was, however. not influenced by the color of plastic films Mulching pepper field with colored PVC film did not show further advantages over the commonly -used black PE film. Herbicidal activity of oxyfluorfen was very strong under natural light or red light conditions, and weak under blue or green light conditions The degree of oxyfluorfen-induced phytotoxicity varied considerably depending upon the light quality and the kind of vegetable crops.

Studies were conducted to investigate the effect of Lasso [Alachlor: 2-Chloro-2'6'-dimethyl-N-(methoxymethyl) acetanilied]on mulched and nonmulched hot pepper filed. Lasso treatment greatly inhibited weed growth and the granular formulation was more effective than emusifiable concentrate in controlling weed growth in both mulched and nonmulched plots. Lasso effect was not apparent about 50 days after treatment. The growth of pepper plant was greatly promoted by mulching and yield of green peppers was more than doubled by transparent polyethylene film mulching. There was no plant in the entire plot which showed apparent phytotoxicity by Lasso treatment.

목적 : 교합성 골수강내 금속정술 후 발생한 대퇴골 간부 골절의 불유합의 치료 결과를 알아 보고자 하였다. 대상 및 방법 : 1990년 5월부터 2000년 7월까지 대퇴골 간부 골절에 대한 교합성 골수강내 금속정술후 발생한 불유합에 대해 치료받은 환자중 1년 이상 추시 가능하였던 33명을 대상으로 후향적으로 조사하였다. 수술 당시 평균 연령은 40세(19~68)였으며, 남자가 27례, 여자가 6례였다. 불유합의 형태는 Weber와 Brunner와 분류 방법에 따르면 과혈관형 10예(30%), 무혈관형 21예(64%), 혼합형이 2예(6%), 무혈관형중에서 감염성이 5예(23%)였다. 결과는 수술 방법에 따른 골 유합 기간 및 불유합, 부정 유합, 감염 등의 합병증의 유무로 평가하였다. 결과 : 수술 방법은 불유합의 원인과 형태에 따라 결정하였으며, 5가지 방법으로 시행하였다. 골수강내 금속정 교환술을 시행한 경우가 7예, 골수강내 금속정 교환술 및 골 이식술을 함께 시행한 경우가 11예, 외고정술 5예, 금속판 고정 및 골 이식술 3예, 해면골 이식술만을 시행한 경우가 7예였다. 골유합 기간은 각각 평균 19주, 17주, 20주, 16주, 15주로서 치료 방법 간에 통꼐학적인 의의는 없었다. 전례에서 술 후 감염이나 불유합, 부정 유합 등은 관찰되지 않았다. 결론 : 교합성 골수강내 금속정술후 발생한 대퇴골 간부 골절의 불유합의 치료에 있어서는 불유합의 원인과 형태를 잘 분석하여 그 원인에 맞는 적절한 치료 방법을 선택하는 것이 골유합을 얻는데 매우 중요하다고 생각된다. Purpose : We analyzed the results of treatment for the nonunion of femur shaft fractures after interlocking intramedullary(IM) nail fixation. Materials and Methods : Thirty-three patients who underwent interlocking IM nailing due to femur shaft fractures from May, 1990 to July, 2000 and followed up for more than one year were evaluated retrospectively. Mean age at the time of operation was 40 year(Range, 19-68). 27 cases were men and 6 cases were women. By Weber and Brunner classification of the nonunion, hypervascular type were 10 cases(30%), avascular type 21cases(64%), mixed type 2 cases(6%). Infected type among the avascular type of noumion were 5 cases(23%). Results were evaluated with bone union by treatment methods and complications. Results : According to the causes and types of nonunion, we performed IM nail exchange in seven cases, IM nail exchange and bone grafting in eleven cases, external fixation in five cases, compression plating and bone grafting in three cases, and only cancellous bone grafting in seven cases. Radiographical union was achieved in 19weeks, 17 weeks, 20 weeks, 16 weeks and 15 weeks respectively. There’s no statistically significant difference between treatment methods. There are no cases of nonunion, malunion and infection. Conclusion : The selection of appropriate treatment method by the cause and type of each nonunion is very important to achieve the bony union in the treatment for the nonunion of femur shaft fractures after interlocking intramedullary nailing.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.
