This study to survey the change of life conciousness of 1040 middle school boys and girls completing the camping in Bak-Dam-Sa Student's Camping Place. I asked them to answer my questionnairess, and then have come to the conclusion from them as follows. 1. The spirit of self-sacrifice After camping, the dissatisfactions and complaints are decreased notably in the case of both boys and girls, and they have became not to avoid the hard work and changed into affirmative attitude to things. Above all, in the case of girls, the have changed into the positive action from the shame and appearance. 2. Self-confidence It turned out that students, both boy and girl altogrther, through camping, could have the opportunity to fine out their merit and demerit; in case of girl students, the could have the opportunity to be able to find out something to please themselves, and in case of bi\oy students, they could have the opportunity to make friends with others. Also, When they were asked if they could express their opinions with confidence, they showed a high positive response with the result of significant changing. 3. Responsibility After camping when they were asked on responsibility, they both boy and girl altogether, positively responded that they never failed to perform their tasks, never gave them up, and their best in everything they did. 4. Public morality After camping, for both boy and girl, positive changes has been brought in on the used of public facilities, fulfillment of every rules in school life, caution of safety during school life and experiences learned at school or at home. 5. Cooperation The result of camping shows that qualities of both boys and girls have meaningfully changed as respects the cooperative relations between friends, recognition of importance in community life, inprovenment of the spirit of collaboration and harmony with friends of teachers.

목 적 : 진폐증은 분진으로 인해 인체의 면역기전이 작용하여 폐섬유화가 진행되는 질환으로, 인체의 면역기전에 작용하는 구리와 아연은 진폐증의 병리적인 진행과정인 폐섬유화에 관여한다. 본 연구의 목적은 초기진폐증 유소견자와 진행된 진폐증 환자의 혈청 구리와 아연의 농도를 정상인과 비교함으로써 체내 구리와 아연의 농도가 진폐증의 섬유화의 진행정도에 따라 변동함을 밝히고, 이를 이용하여 폐섬유화의 진행정도를 추정할 수 있는 지표를 제시하고자 한다. 방 법 : 진폐정밀기관에 내원한 초진내 원자 100명과 진폐요양기관에 입원한 진폐증 환자 100명을 선정한 후 흥부사진소견을 ILO 분류법의 진폐진행정도에 따라 각각 세 군(Stage Vl, V2, V3 & Stage Pl, P2, P3)으로 구분한 후 각 군의 혈청구리와 아연의 농도를 비교분석하였다. 대조군으로는 폐결핵, 심근경색, 뇌경색을 경험한 적이 없는 일반인 100명을 선정하였다. 결 과 : 초진내 원자군의 혈청 구리농도는 섬유화의 진행단계에 따른 유의한 차이를 보였으며, Stage V3에서 가장 높았다. 입원환자군에서는 혈청 구리농도가 대조군과 유의한 차이를 보이지 않는데 (p=0, 152), 이는 입원환자의 불량한 영양상태와 건강상태 때문인 것으로 추정된다. 초진내원자군과 입원환자군의 혈청 아연농도는 섬유화의 진행에 따라 통계적인 차이를 보였으며, Stage V2와 Stage P2, P3에서 각각 대조군에 비해 유의하게 낮았다. 혈청 아연과 구리농도의 비또한 양군에서 섬유화의 진행에 따라 의미있게 높았는데, 섬유화가 현저히 진행된 단계 (Stage V3, Stage P2, P3)에서 대조군과 의미있는 차이를 보였다. 결 론 : 초진내 원자와 입원환자의 혈청 Cu/zrl 비는 섬유화의 진행정도가 현저할수록 대조군에 비해 유의하게 높게 나타났다. 진폐증 환자들의 혈청 Cu/zn 비는 진폐증의 폐섬유화의 진행정도를 추정함에 있어 상당히 유용한 지표로 이용될 수 있으며, 폐섬유화의 진행과정에서의 혈청 구리와 아연의 작용기전을 이용한 치료방법의 마련에도 도움이 될 것으로 판단한다. Objectives : Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. Methods : The subjects of thls study was 200 diagnosed persons as pneumoconiosis, of whom 700 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and compared. Results : The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zlnc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. Conclusions : As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

Over the last few year, there has been a growing interest in quantitative representation of heat transfer phenomena in weld pools in order to relate the processing conditions to the quality of the weldment produced and to use this information for the optimisation and robotization of the welding process. Normally, a theoretical model offers a powerful alternative to check out the physical concepts of the welding process and to calculate the effects of varying any of parameters. To solve this problem, a transient 2D(two-dimensional) heat conduction model were developed for determining weld bead geometry and temperature distribution for the GMA welding process. The equation was solved using a general thermofluid-mechanics computer program, PHOENICS code, which is based on the SIMPLE algorithm. The simulation results showed that the calculated bead geometry from the developed model reasonablely agrees with the experiment results.

Following recent advanced industrialization, the amount of polyurethane to use as thermal insulating materials, upholstery, mattresses and packing materials in automotive and furniture industry is increasing world-widely, and the number of polyurethane-producing worker will be increased. Because the numerous organic solvents are used in polyurethane-producing factory, the workers in this work site is exposed to many organic solvents. Of the organic solvents, Toluene Diisocyanate(TDI) has many hazardous effects to human. The effects of TDI on human are the irritation to respiratory mucosa and gastrointestinal symptoms. Conjunctival irritation, dermal inflammation (redness, pain, vesicular formation) and gastrointestinal symptom(nausea, vomiting. abdominal pain) are reported just after short-term exposure of TDI. TDI is known to give rise to bronchial asthma, as the immune disorder. And because of strongly volatile characteristics of TDI, it is suggested as a more injurious material to human health, especially human immune system, than other organic solvents. Bronchial asthma inducing mechanism of TDI is not clearly known, but on the analogy of TDI induced symptoms and recent studies, early-onset asthma is type I hypersensitivity reaction mediated by immunoglobulin E(IgE), and late-onset asthma is maybe type III hypersensitivity reaction by circulating IgG. And we know that the complicated human immune function is likely to move in such that mechanisms, there are not studies on immune indices evaluating the bronchial asthma-related immune function. The evaluation of change patterns of humoral immunity including IgE and IgG and cellular immunity including T-helper cell. T-suppressor cell and T-cytotoxic cell will be helpful to evaluate exposure degrees and prognosis in TDI exposed workers. Because TDA(toluene diamine) as a biological exposure index of TDI becomes the focus of interest, we know that a study on the correlation between urinary TDA and air TDI and immunological indices will make a contribution to biological effect monitoring indicies. We examined human immunity indicators such as WBC, %Lymph (percentile of Lymphocyte in WBC), %T-cell(percentile of T-lymphocyte in total lymphocyte). CD4, CD8, C3, C4, IgA, IgG, IgM, IgE in peripheral blood to evaluate the health hazard of the TDI-exposed workers. And we examined TDA to evaluate correlation between exposure and effect. Total 90 subjects was selected, 45 workers who worked in the polyurethane-producing factories as an exposed group, and 45 cases who were office workers(10 cases), other blue collors(27 cases), and medical college students(8 cases) as a control group. And the results were as follows; 1. The logarithm of IgE-Log10(IgE)±SD-in peripheral blood of a exposed group was significantly higher than a control group, 2.22 ±0.62 in case group compared with 1.98±0.53 in control group. (p<0.05) 2. IgA and IgM in the polyurethane-producing workers were 261.02±83.12㎎/㎗, 151.97 ±59.64 ㎎/㎗, respectively, and 292.77±100.45, 179.17±100.78 in control group. IgA and IgM was slightly lower in polyurethane-producing group than control.(p>0.05) 3. WBC, %Lymph. %T-cell, C3, C4, CD4, CD8, CD4/CD8 ratio and IgG in case group were 6.391.1 ea/㎖, 37.53 %, 59.54 %, 76.68 ㎎/㎗, 0.76×10(9) ea/L, 0.63×10(9) ea/L, 1.39, and 1606.29 ㎎/㎗, respectively, and 6,974.7 ea/㎖, 35.12 %, 59.64 %, 71.95 ㎎/㎗, 33.94 ㎎/㎗, 0.80×10(9) ea/L, 0.61×10(9) ea/L, 1.39, and 1581.51 ㎎/㎗ in control group. There was no statistical significance between two groups.(p>0.05) 4. In the comparison of each other companies, average of individual urinary TDA in polyurethane paint manufacturing companies is higher than that of polyurethane sponge foaming companies. And, the concentration of 2.6-TDA which is a metabolite of well-vaporized 2.6-TDI is higher than that of 2.4-TDA in the polyurethane sponge foaming companies. But, the concentration of 2.4-TDA which is a metabolite of illvaporized but well skin-absorbed 2.4-TDI is higher in polyurethane paint manufactures. 5. There were no statistical significance in the correlations between individual urinary TDA and immunologic indices.

Low back pain in computer terminal operators is a very common but important symptom. While the occupational risk factors of low back pain were approved obscurely, there have been few studies on analysis or understanding of occupational risk factors. Therefore, we studied occupational risk factors of low back pain, especially for ergonomic factors as well as general characteristics of workers. We selected 98 subjects for this study, computer terminal operators ordinary using computers in Pusan. We calculated the subjective severity of low back pain of each operator by the Low Back Pain Scoring System. The relation of low back pain score to general characteristics of worker was also analyzed. We analyzed the relationship between low back pain score and individual efforts to prevent low back pain. We measured the ergonomic factors of each computer terminal operator-Trunk Inclination(TI), Arm Flexion(AF), Elbow Angle(EA), Head Tilting(HT), Knee Angle(KA), using of foot plate and gap between the popliteum and chair. The correlations between these ergonomic factors and low back pain score were then analyzed. And the results are as follows: 1. The prevalence rate of low back pain in computer terminal operators was 39.8% in this study, when low back pain score was converted by the low back pain scoring system. 2. According to general characteristics of workers related to low back pain, the scores were higher in the older age group, the married and the longer work carriers.(p<0.05) 3. In the analysis of the relationship between low back pain score and individual effort to prevent low back pain, regular exercise, history of schooling for prevention of low back pain, and declaration of intention to participate in low back pain education or exercise were stastistically significant(p<0.05). And the more severe the low back pain, the higher the intention to participate in low back pain education they had in this study. 4. In the analyses of relationships or correlations between low back pain score and each of the 7 categories of ergonomic factors, only head tilting had a weak reverse correlation with low back pain(r=0.2999, p<0.01). From now on, cohort studies for the risk factors of low back pain of workers, who have been forced to work in non-ergonomical positioning at the work site, will be necessary. On the background of these ergonomic studies, the occupational health profession should be required to manage ergonomic working conditions.

남연,오차재,박정래,이동준,조병만,이수일 大韓産業醫學會 2002 대한직업환경의학회지 Vol.14 No.1

목 적 : 부산지역의 근로복지공단에서 1991년부터 1999년까지 과로사 관련 보상심사가 이뤄진 총 219례를 대상으로 과로사의 발생양상과 그 인정여부에 영향을 밀치는 요인을 밝힘으로써 향후 과로사 관련 연구의 기초적 자료를 제공하고자 하였다. 방 법 : 부산지역의 3개 근로복지공단 지사에 소장된 과로사 심사기록을 대상으로 재해자의 인구통계학적 변수와 소속사업장과 근무환경에 대한 변수, 사망원인질환과 기존질병력, 업무상 과중부하의 성격과 분류, 직무수행성과 직무기인성 여부에 대해 조사하였다. 그리고 행정기관의 과로사 인정에 영향을 미치는 요인들을 평가하였다. 결 과 : 1. 전체 219례 중 135례(61.6 %)가 과로사로 인정을 받았으며, 96년 이후 매년 50례 이상의 보상신청이 이뤄져 왔다. 전체의 30.6 %가 50인 미만의 영세사업장 소속이었고, 직업운전사와 경비 직종이 34.7 %로 높았다. 연령층은 50대 이상이 48.8 % 였고, 하루 12시간 이상의 근무자가 29.6 % 였다. 근무형태에서는 교대근무와 심야근무 등의 불규칙 근무형태가 37.5 %였으며, 새로운업무에 배치된 지 6개월 이내에 발생한 경우가 21.5 %였다. 2. 사망원인으로는 뇌출혈 등의 뇌혈관계 질환이 전체의 49.8 %로 심장질환보다 많았고, 현행법령상의 인정범위에 속하는 경우가 85.4 %였다. 또한 선행질병력이 48.9 %에서 나타났는데, 대다수가 고혈압 등의 순환기 질환으로 확인되어 이들 병력자들의 보건관리에 중점을 둘 필요를 보였다. 3. 운전과 감시·정밀작업, 위험작업, 잦은 장기 출장 등의 위험요인에 노출된 경우가 전체의 53.9 %였고, 재해에 선행된 돌발사건이 전체의 17.8 %에서 관찰되었다. 업무상 과중부하에서 업무량증가와 업무시간연장이 전체의 64.7 % 였고, 6개월 이상의 장기적인 육체적, 정신적 과중부하가 있었던 경우가 42.5 %였다. 이 결과로 볼때 현행 법령상의 장기적인 과로에 대한 인정범위가 보다 확대되어야 할 필요를 보여준다. 4. 과중부하가 발생에 기여한 것으로 평가된 예가 전체의 76.3 %로 실제 인정율보다 높았다. 이중 충분요인으로 작용한 경우가 43.6 %, 부분요인인 경우가 10.4 %, 변경·촉진요인인 경우가 22.3 %였다. 5. 과로사 인정여부와 각 변수간의 로지스틱 회귀분석에서는 해당 업무의 근무경력이 6개월미만인 경우가 교차비 6.76(p=0.016), 사망질환이 법규상의 뇌심혈관계질환에 포함되는 경우가 교차비 3.00(p=0.034)을로 유의하게 높았다. 업무상 과중부하의 증가가 있는 경우는 교차비가 2.02로 높았으나 통계적 유의성은 다소 낮았다(p=0.081). 반면 50대 이상의 고령층과 기존 병력자의 경우는 상대적으로 불인정되는 경향을 보여 현행 행정기관의 인정기준이 과로에 민감한 대상층을 포괄하지 못하고 있음을 보여주었다. 결 론 : 부산지역에서의 과로사는 주로 50인 미만의 영세사업장 중 운전업, 경비업 등에 종사하는 40대 이상의 중·고령층 근로자에서 많았다. 재해자중 다수에서 뇌·심혈관계질환 병력이 확인되었고, 행정기관의 과로사 인정에는 법규상 인정범위의 뇌·심혈관계질환으로 사망한 경우와 재해자의 근무경력이 6개월 미만인 경우에서 인정되는 경우가 의미있게 높았다. 반면 기존 질병력이 있거나 50대 이상의 고령층의 경우 과로사로 인정되지 못하는 경우가 보다 많게 나타났다. 그러나 본 연구에서는 장기적인 과로와 과중부하를 유발하는 고위험직업에서의 과로사 빈도가 높아 현행 법규상의 과로인정기간의 범위를 넓혀야 할 것이고 직업에 대한 고려를 포함하는 인정기준의 검토와 개선이 요구된다. 그리고 과로사를 예방하기 위하여 업무시간 및 업무량의 개선과 관리가 필요할 것으로 판단된다. Onjectives : Karoshi is a word meaning death from work-overload. Work-related diseases due to continuous overwork are primarily cerebro- and cardio-vascular in nature. In korea, despite an increase in the incidence of Karoshi, it is not easy to recognise by workmen's compensation in Korea. This study intended to establish basic information concerning the incidence of Karoshi. Methods : 219 cases were collected based on workers' compensation records of three Busan Regional Centers of Labor Welfare Corporation from 1991 to 1999. The size of workplace, occupation, daily working time, type of working schedule, job tenures, characters of work-overload and duration of work-overload were investigated according of subgroups of general characterictics. Both univariate and multiple logistic regression analyses were userd to estimate the relationship between risk factors and a recognition of Karoshi. Results :1. 61.6 % of total cases were recognized as Karoshi. 30.6 % occurred in a small workplace of less than 50 workers, 34,7 % were drivers or guardss, and 48,8 % were more than 50 years old. Additionally, 29.6 % worked more than 12 hours, 37.5 % were irregular hours and shift workers and 21.5 % of the total had been on the job less than 6 months. 2. Of the causes of death, 49,8 % was cerebro-vascular diseases and it was more than cardio-vascular ones. And 80.4 % of total cases was belonged to the recognition-category of the Labour Ministry's Law. The previous desease history was found on 49.8 % of all cases. Of them, hypertension was most common as 21.9 %. 3. 53.9 % of patients were exposed to job hazards such as driving, monitoring, guarding, risky jobs and frequent long-term official trips. 64.7 % recorded a increased work-overload of job contents and working hours. Of the several types of work-overload, 42.5 % displayed long-term physical and psychotic work-overload and 22.2 % exhibited job characteristic work-overload. 4. In this study, work-overload was associated with the incidence of Karoshi in 76.3 % of cases. This rate was higher than the recognition of Workmen's compensation recorded by the Korea Labor Welfate Corporation. Of these, 43.6 % belonged to sufficient factors, 10.4 % partial factors, and 22.3 % were due to aggravating factors. 5. Logistic regression demonstrated that death due to cerebro- and cardio-vascular disease, short-tenure within 6 month was significantly associated with a recognition of Karoshi (p=0.034, OR=3.00, CI=1.09~8.30/p=0.016, OR=6.76, CI=1.43~32.07 respectively) and that an increase of work-overload was also associated, but its statistical significance was slightly lower(p=0.081, OR=2.02, CI=0.91~4.46). However, no association was found between this recognition and overtime work, hazardous job, irregular work schedule, low-income, injury-onset place, or small size of workplace. The elderly group(>50years old) and those with a previous disease history were negatively associated with recognition although the statistical associaltion was low. Conclusions : Karoshi in Busan occurred frequently in a small workplace of less than 50 workers, especially drivers or guards. Additionally, these cases worked more than 12 hours, were irregular hours and shift workers. The death due to cerebro- and cardio-vascular disease, short-tenure within 6 month was significantly associated with a recognition of Karoshi. However Karoshi in this study occurred frequently in overtime work and high risk groups of work-overload. Therefore, for prevention of Karoshi, work-overload and overtime work need improved and controled.

부산지역 신발제조업 근로자중 유기용제에 폭로되고 있는 150명을 폭로군으로 하고, 일반사무직 근로자 53명을 대조군으로 하여 인적특성, 직업에 대한 만족도, 자각증상, 작업과 관련된 스트레스의 정도를 조사하고, 유기용제 폭로량의 지표가 되는 요중 마뇨산 및 근로자 건강진단 항목인 혈중 요소질소, 혈청 크레아티닌 그리고 조기 신기능 장애의 지표로 알려진 요중 NAG 활성치를 측정하여 얻은 바를 아래와 같이 요약한다. 1. 요중 NAG 활성치는 폭로군에서 4.63U/g creatinine, 대조군에서 2.95U/g creatinine로 폭로군에서 높게 측정되었고(p<0.05), 유기용제 폭로에 의한 신기능 변화에 민감한 결과를 보였다. 2. 설문조사에서 직업에 대한 불만족, 이직을 원하는 경우, 건강에 대한 염려, 직업과 관련된 스트레스 및 유기용제 폭로와 관련된 증상호소가 대조군에 비해 폭로군에서 유의하게 증가되어 있어(p<0.05), 유기용제에 폭로되고 있는 신발제조업 근로자들의 보건관리는 산업보건학적 측면에서 매우 중요한 것으로 나타났다. 3. 폭로군중 근무기간 5년 이상인 대상자에서 요중 NAG 활성치는 5.92U/g creatinine, 근무기간 5년 미만인 경우 4.34U/g creatinine으로, 유기용제 폭로 기간이 길어짐에 따라 요중 NAG활성치는 통계학적으로 유의하게 증가되어 있었다(p<0.05). 4. 요중 NAG활성치는 근무기간을 가중한 톨루엔 총 폭로량과 유의한 정의 상관관계를 보여(p<0.05), 용량-반응관계를 보여 주었다. 이상의 결과에서, 복합유기용제에 만성적으로 폭로되는 근로자들에 공통적으로 발생할 수 있는 조기 신기능 장애를 감시하기 위하여, 요중 NAG활성치를 측정한 자료를 이용하면 유기용제 폭로 근로자들의 보건관리를 위하여 자료를 제공할 수 있을 것으로 생각된다. Personal characteristics, degree of satisfaction for work, subjective symptoms, and stress related to working condition were investigated from 150 workers exposed to organic solvents in shoe factories and 53 official workers in Pusan area, and urinary hippuric acid concentration which represented the amount of exposed organic solvents, BUN and serum creatinine which were renal function tests for worker's health examination and urinary N-acetyl-β-D-glucosaminidase activity were measured. The results obtained were summarized as follows. 1. The mean value of urinary NAG activity of exposed group was higher than that of control group(p<0.01), and subjects whose NAG activities were over refrence range in exposed group were far more than in control group(p<0.05), therefore urinary NAG activity was a sensitive test for the change of renal function due to exposure of organic solvents. 2. Unsatisfaction for occupation, want to change occupation, worry about health, stress related to job and symptoms related to exposure of organic solvents investigated by questionnaire were higher in exposed group than in control group, therefore the health management for workers exposed to organic solvents in shoe factories was important in the viewpoint of occupational medicine. 3. The mean value of urinary NAG activity in the subjects whose working duration were over 5 years was higher than in the subjects whose working duration were over 5 years was higher than in the subjects whose working duration were under 5 years, therefore the longer exposured duration was, the higher urinary NAG activity was. 4. Urinary NAG activity had positive correlation with time weighted amount of total toluene exposure therefore dose-response relationship was suspected. As above results, it will be very useful to apply the data of urinary NAG activity to the health management of workers exposed to orgaic solvents in order to monitoring of early renal dysfunction which was common in the workers chornically exposed to mixed organic solvents.
