본 연구는 40세 이상 중년의 남자 근로자 253명을 대상으로 신체 적합도 및 여가중 신체 활동과 혈중 지질 중 심혈관질환 발생에 특히 중요한 혈중 총콜레스테롤 값, HDL 콜레스테롤 값 및 총콜레스테롤/HDL 콜레스테롤 비와의 관련성을 알아 보기 위하여 시도된 단면조사연구이다. 단순분석에서 혈중 총콜레스테롤 값과 유의한 상관 관계가 있는 변수는 신체 적합도(r=-0.27), 비만지수(r=0.27)였다. 여가중 신체 활동은 총콜레스테롤 값이 170mg/dl 이상군에서만 총콜레스테롤 값과 유의한 상관관계(r= -0.20)가 있었다. HDL 콜레스테롤 값과 유의한 상관관계가 있는 변수들은 신체 적합도(r=0.15), 비만지수(r=-0.22)및 1주간 음주량(r=0.14)이였다. 총콜레스테롤/HDL 콜레스테롤 비와 유의한 상관관계가 있는 변수들은 신체 적합도(r=0.23), 비만지수(r=0.32), 총흡연지수(r=0.13), 1주간 음주량(r=-0.13) 및 야채 선호도(r=0.13)이었다. 신체 적합도는 안정시 맥박수와 중등도의 상관관계(r=-0.66)가 있었고, 여가중 신체 활동(r=0.19)및 비만지수(r=-0.18)와도 유의한 상관관계가 있었다. 다중회귀분석(Multiple linear regression) 결과 혈중 총콜레스테롤 값과 유의한 관련성을 보이는 변수는 신체 적합도(beta=-0.23)와 비만지수(beta=0.18)이었다. HDL 콜레스테롤 값과 유의한 관련성을 보이는 변수는 비만지수(beta=-0.25)뿐이었다. 총콜레스테롤/HDL 콜레스테롤 비와 유의한 관련성을 보이는 변수는 비만지수(beta=0.30)와 신체 적합도(beta=-0.16) 및 야채선호도(beta=0.14)이었다. 결론적으로 중년 남성 근로자들에서 신체 적합도는 비만지수와 함께 혈중 총콜레스테롤 값, HDL 콜레스테롤 값, 총콜레스테롤/HDL 콜레스테롤 비의 중요한 관련 요인이었다. 여가중 신체 활동은 혈중 총콜레스테롤 값이 170mg/dl 이상인 군에서만 혈중 총콜레스테롤 값과 관계가 있었고, 신체 적합도와는 관련성이 유의하지만 크지 않았다. 따라서 신체 적합도가 여가중 신체 활동보다 혈중 지질 농도의 더 중요한 관련요인이며, 앞으로 신체 활동에 관련된 역학적 연구에서 신체 적합도가 독립적이고 중요한 요인으로 추가되어야 할 것이다.

This study performed a structural questionnaire survey and non-structural interview of the ladies apparel manufacturers in Daegu on the qualification for the employees, skills required for job performance, job training, automatic manufacturing systems, and the use of computer. The results are as follows. 1. Almost all of the apparel manufacturing systems were Pair System, except one Line System in one company. In terms of outsourcing, most of the manufacturers answered “yes,” and in 1998 the outsourcing process was sewing, but in the year 2002, outsourcing has been increased :12 manufacturers(57.1%) outsourcing most of the processes except patterning, 3(14.3%) outsourcing the finish of sewing. 2. The workforce of 1998 and that of 2002 shows a significant difference(P＜. 01) between office work and management. The number of office workers has decreased from 15 down to 5.3 people. On the other hand, that of the management has slightly increased from 5.3 to 9.2 people. The number of the manual workers has decreased from 32.2 to 28.7 people. And the number of tailoring and patterning workers has slightly decreased, but the number has increased in sewing from 3.7 to 7.0 people. 3. The wage of an employee shows a significant difference between a sewing assistant(P＜. 01) and a production manager(P＜. 05), and the wage of a sewing assistant, in particular, has slightly raised from ￦905,000 to ￦1,054,000. 4. The qualifications required of employees are “cooperative human relations”(30.8％), “diligence,” and “ability for job analysis”(26.9％), and “positive thinking” (15.4％) in 1998, and “ability for job analysis”(38.5％), “cooperative human relations”(34.6％), and “positive thinking” (15.4％) in 2002. The areas for job openings are significantly different(P＜. 01) depending on the year. Job openings in the design section has increased from 1(3.8％) to 16 manufacturers (61.5％), and decreased in tailoring section from 22(84.6％) to 2 manufacturers(7.7％). Job openings in the sewing section have increased form 2(7.7％) to 6 manufacturers (23.1％). In terms of sex of the employees, there is a significant difference(P＜. 001). 19 companies(73.1％) wanted “male” in 1998, but 8 companies(30.8％) answered that they want “female” and 17 companies(65.4％) answered that “it does not matter.” About the educational background, there was a significant difference between the years. The number of the companies that want junior college graduates with an associate degree has increased(15 companies(57.7％). There was a significant difference(P＜. 05) in major of the employee. The number of the companies that want fashion majors has increased from 5(19.2％) to 20(76.9％). 5. In terms of job skills required, there was no significant difference. In 1998, “production skills” (46.2％) and “ability for job analysis” (26.9％) were required, and in 2002, “ability for job analysis” (42.3％) and “emotional skills” (26.9％). 6. In regard to training for job skills, “fashion professional training” has slightly decreased from 65.4％ in 1998 to 46.2％ in 2002, however, “training for job analysis” has slightly increased from 30.8％ in 1998 to 46.2％ in 2002, which indicates the fact that “fashion professional training” and “ability for job analysis” have been emphasized. 7. The number of the manufacturers purchased apparel CAD has increased from 1(3.8％) to 3(11.5％), and the number of the manufacturers that have no plan for purchase has increased from 16(61.5％) in 1998 to 15(57.7％), still taking up a big proportion. 8. About the use of computers in manufacturing, there is a significant difference(P＜. 05). The number of the manufacturers using computer has increased from 5(19.2％) to 15(57.7％) and that of the manufacturers which do not use computers has decreased from 17(57.7％) to 8(30.8％). 9. In the interviews with the owners of the manufacturers, they pointed that schools should give more weight on practical training courses, the invitation of experts in the specific field, complex production systems, training courses for sewing, field trip courses, and furthering specialty education, personality and vocational education.

복합유기용제를 취급하는 근로자들을 대상으로 유기용제의 폭로가 신경행동기능에 미치는 영향을 평가하기 위하여 대구지역의 중소규모 사업장에서 톨루엔, 크실렌, 메틸에틸케톤 및 신나에 만성적으로 폭로되는 유기용제 폭로군 48명과 폭로군과 같은 사업장에 근무하면서 유기용제에 폭로되지 않은 대조군 50명을 대상으로 1996년 8월에서 10월까지 연령, 교육수준, 음주, 흡연량 및 직업관련 변수들을 조사하고 Neurobehavioral Core Test Battery의 검사항목 중 Benton visual retention검사, 숫자부호 짝짓기, 숫자 외우기, 목적점찍기를 시행하였다. Benton visual retention검사는 폭로군이 7.9개, 대조군이 8.2개로 두군에서 유의한 차이가 없었으며, 숫자부호 짝짓기의 경우 폭로군이 55.6개, 대조군이 62.1개로서 폭로군이 유의하게 적었다(p<0.01). 숫자 외우기의 총 점수와 거꾸로 따라외우기의 점수가 폭로군에서 유의하게 적었으며(p<0.05, p<0.01) 목적점찍기의 바르게 찍은 점의 개수가 폭로군에서 유의하게 적었다(p<0.05). 연령의 변화에 따른 신경행동기능의 일관성있는 변화는 없었으나 Benton visual retention검사의 경우 젊은 연령군이 고연령군에 비해 대조군에서 유의하게 높은 성적을 보였다(p<0.05). 부호숫자짝짓기의 경우 폭로군과 대조군 모두에서 학력이 높을수록 검사성적이 유의하게 높은 경향을 보였다(p<0.05). 숫자부호짝짓기에서 섭취하는 알콜의 량이 많을수록 폭로군의 부호숫자짝짓기 검사성적이 감소하는 경향을 보였다(p<0.05). 목적점찍기의 경우 폭로군에서 흡연량이 증가할수록 성적이 감소하는 경향을 보였다(p<0.05). 신경행동학적 검사성적을 종속변수로 하고 유기용제의 폭로유모, 나이, 학력수준, 알콜 및 흡연량을 독립변수로 한 다중회귀분석에서 Benton visual retention검사는 연령이 증가할수록 그 성적이 감소하는 경향을 보였으며(p<0.05), 숫자부호짝짓기는 학력이 높을수록 성적이 증가하는 것으로 나타났다(p<0.01). 숫자외우기에서는 유기용제의 폭로가 유의한 변수로 채택되었다(p<0.01). 목적점찍기의 총점수는 흡연량과 교육수준이(p<0.01), 바르게 찍은 개수는 흡연량과 유기용제의 폭로가 유의한 변수로 채택되었다(p<0.05). 유기용제의 폭로에 의해 지각반응(perception-response)과 단기기억능력(short-term memory)이 민감하게 영향을 받는 것으로 평가되었으며, 특히 허용 농도이하에서도 장기적으로 폭로되는 경우 폭로자의 신경행동기능에 변화를 초래할 수 있음을 확인할 수 있었다. NCTB에 의한 신경행동기능의 평가는 신경독성물질의 폭로이외에도 연령과 교육수준에 영향을 받으며 특히 지속적 운동능력의 경우 흡연에도 다소 영향을 받을 가능성을 제시하였다.

목적: 최근 컴퓨터가 대량 보급되면서 VDT 증후군이 점차적으로 증가하고 있다. VDT 증후군은 VDT 작업자들에게 나타나는 근골격계 질환, 신경정신계 장애, 눈의 긴장, 피로, 자극과 충혈 등 안과적 증상을 포함한다. VDT 증후군의 환경요인으로는 전자파, 컴퓨터 화면의 크기, 밝기, 조명, 모니터 및 작업대의 높낮이, 작업시간, 작업의 종류, 작업자와 스크린과의 거리, 실내습도 및 온도, 사무실내의 공기오염, 환기 등이 있다. 본 연구에서는 근거리 시각 작업으로 인한 VDT 증후군에서 나타나는 주요 신체증상 및 신체 및 심리적으로 영향을 줄 수 있는 환경적 요인을 조사하였다. 방법: 연구대상자는 19세부터 28세사이의 남자 54명, 여자 66명으로 총 120명이었다. 책이나 문서 읽기, 컴퓨터 작업 등에 대한 근거리 작업을 할 때에 나타나는 신체적 증상과 육체적 불편함을 설문지를 이용하여 조사하였다. 조사항목에는 근업작업에 따른 주요 신체 증상과 눈의 자각 증상, 작업환경에 대한 만족도, 키보드, 마우스 사용시의 손목 통증 경험 등을 포함하였다. 결과: 장시간 컴퓨터, 문서, 전자기기를 사용할 때에 대부분(70%)이 신체적인 통증을 느끼는 것으로 나타났다. 통증부위는 주로 목과 허리(57.1%), 눈(45.2%), 두통(31%) 등이었다. 환경적 요인에서는 적절치 못한 조명으로 눈의 통증을 호소하는 사람들이 78.3%였다. 대부분의 증상은 '눈의 피로'(38.3%), '눈의 건조성'(31.9%), '눈의 흐릿함'(23.7%)이었다. 대상자들은 의자에 대한 불편함을 호소하였고 키보드, 마우스 사용 때 손목의 통증은 대부분 경험하였다. 결론: 전자기기, 문서 등을 이용할 때 빛, 공간, 자세, 작업대 등의 다양한 환경적 요인들이 조화롭지 못해 눈의 피로, 신체적인 피로감을 느낄 수 있다. 따라서 문서작업을 할 때에는 휴식시간에 대한 자기관리와 같은 예방법을 개발하여 눈의 피로를 줄여야 할 것이다. 또한 지속적인 연구를 통해 근골격계 질환 예방을 위해 최적의 시각적인 환경을 위한 인간공학적 디자인으로 작업환경을 바꾸어야 할 것이다.

For the analysis of mortality differentials by socioeconomic factors based on death registration data, we have considered four variables : place of residence, educational attainment, marital status and occupation. The age range adopted were 5 to 64 years of age for place of residence, and 25 to 64 years of age for the other factors. The mortality differentials by socioeconomic variables were clear and in the expected direction: mortality levels among urban residents, better educated groups, and non- agricultural workers were lower than among the other sub- groups. The average mortality level in rural areas is much higher than in urban areas : the rural mortality levels were at least double the urban levels at ages below 40 years, but became smaller after age 40, and no clear differentials by urban I rural residence increased until 1974~76 for the both sexes, but since the then differentials have declined slowley for both sexes. This changing pattern of mortality differentials by place of residence can be explained by historical socioeconomic development : the development generally started in urban areas, and rural areas followed : in the course of socioeconomic development the differences between the death rates in the two areas became smaller and finally the mortality levels in the two areas became nearly the same, as is found in the developed countries nowadays. The inverse relationships between mortality and educational level became stronger between the periods 1970~72 and 1984~86, but showed the same atterns of mortality differentials in both period : larger differences among the younger age groups, and for males, than among the older age groups, and for females. The increasing mortality differentials in the fourteen-year period between 1970~72 and 1984~86 were caused by inadequate living standards of the non- educated, whose proportion in the total population, however, dropped sharply during that period. Also, the much lower proportions of low - educated groups or of persons with no formal education among males than females helped to establish the clearly pronounced differentials. The mortality differentials by marital status in Korea showed the usual pattern : the mortality rates of the married in each age and sex group were clearly lower than those of others during the fourteen-year period between 1970~72 and 1984~86. In Korean society which remotes universal marriage, the never married recorded especially high death rates, presumably mainly because of ill - health, but also possibly because of the stigma attached to celibacy. However, the mortality differentials by marital status changed with the changes in the proportionate distribution by marital status during the period : the differences between the death rates of the married and never married groups became smaller, the proportion of the never married group increased : in contrast, the differences between mortalities of the married and widowed / divorced / separated groups widened, with the decrease in the proportion of the later group ; this tendency was perticularly marked for females. Occupational groups also showed clear mortality differences : among four occupational groups mortality of males was highest among agricultural workers and lowest among 'professional, admi-nistrative and clerical workers, However, when the death rates were standardized by educational level, the death rates by occupation in age group 45~64 years were nearly the same (excet for the mixed group consisting of unemployed, students, military servicemen and unknown). Therefore, the clear mortality dfferentials by occupation in Korea resulted mainly from the differences in educational level between different occupation groups. Since socioeconomic characteristics are related to each other, the net effect of each variable was examined. Each of the three variables - ducational level, marital status and urban / rural residence affected significantly Korean adult mortality when the effects of the other variables were controlled. Among the three variables educational level was the most important factor for the determination of the adult mortality level. When male's occupation was added to the above three variables, the effects of occupation on adult mortality were notably smaller after control for the effects of the other three variables while the net effects of these three variables were nearly the same irrespectively whether occupation was included or not. Thus, the differences in educational level (mainly), place of residence and marital status bring out the clear differences in observed mortality levels by occupation.

Objective : To estimate the magnitude of psychosocial distress and examine eligible factors associated with the development of psychosocial distress in Korean employees, using a nationwide sample. Methods : A total of 6,977 workers were recruited from 245 companies. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, social support at work, personality traits (locus of control, type A behavior pattern), self-esteem, and psychosocial distress. Results : The results showed that 23 % of workers were categorized as high stress, 73% as moderate, and 5% as normal. Hierarchical multiple regression analysis showed that psychosocial distress was more common in younger workers, both male and female. Regular exercise was negatively associated with increase of psychosocial distress. In job characteristics, as expected, low decision latitude, high job insecurity, and low social support at work were related to high psychosocial distress. Personality traits such as locus of control and type A behavior pattern, and self-esteem were more powerful predictors of psychosocial distress than general characteristics, health-related behavior, and job characteristics. There were some gender differences. While men who are less educated and single (unmarried, divorced, and separated) experienced higher levels of psychosocial distress than those who are educated and married, women who feel high job demand experienced higher levels of psychosocial distress than those who feel low job demand. Conclusions : The proportion of the high stress group was higher than expected, and psychosocial factors like social support and personality characteristics (e. g. locus of control, type A behavior pattern and self-esteem) were more significant factors for psychosocial distress than other variables. This finding suggests that some psychosocial factors, especially inadequate social support, low self-esteem and lack of internal locus of control for the development of psychosocial distress, will also operate as an intervention strategy in the worksite stress reduction program. It is strongly required that worksite stress reduction programs should be established in at both occupational and level as well as in individual levels.

In this study, grade of subjective symptom appealed by laborer of Jeollabuk-do was evaluated using questionary regarding factor made effect on musculoskeletal disease and in addition, studied relationship with health promotion life style of them. Based on the result, relationship of general characteristics of musculoskeletal subjective symptom and life-style of the subjects was concluded as below. 1. General characteristics of study subjects were as following. Ratio of male was higher as 57.7% of male and 42.2% female and age distribution was 5.1% of 20s, 34.99% of 30s, 36.3% of 40s and 23.7% of 50s and therefore, $30{\sim}40$ aged groups showed highest ratio. Most subjects (74.9%) was married status and in case of education level, high-school graduate and dropout (23.3%) and over-college graduate (46.8%) showed highest distribution. $1{\sim}2$ Mil. KRW (29.5%) and $2{\sim}2.99$ Mil. KRW (21.2%) is the main income distribution and however there was high ratio of non-reply (29.0%). In case of employment period, $10{\sim}14$ years (15.3%) and over 15 years (29.6%) showed highest ratio and there were many non-reply (39.4%) and in addition, 67.6% replied as own house and 14.3% as lease on deposit base in question of residence type. 2. Subjects showed high ratio of subjective symptom appeal of 62.79% and many cases (50.23%) appealed 1 or 2 symptoms. Symptom by body region was 29.8% (waist), 27% (shoulder), 21.2% (knee), 15.5% (neck), 9.5% (ankle), 8.1% (wrist) and 5.0% (elbow) in order. In case of relationship with general characteristics, female comparing with male, non-residence of own house, subjects with lower education level and employment period of $10{\sim}14$ years showed higher appeal rate and kind of symptoms than others. Therefore, it was concluded that rate of musculoskeletal symptom appeal have close relationship with gender, level of living, education level, age and employment period. 3. In case of severe pain of upper body except waist and ankle, it was appealed in both or right side and it means that upper body pain is originated from right side and right region pain is transited to both region pain. In addition, there was 39.41% of non-reply to existence of right-left region pain and therefore, it was evaluated that, in may cases, there was no awareness of their own symptom condition even on subjective symptom. 4. Degree of pain was, as pain over middle level, evaluated as 2.79 on full mark of 4.0 and in order of waist (2.97), ankle (2.83), knee (2.82), wrist (2.82), neck (2.79), shoulder (2.70) and elbow (2.62). In addition, 71.97% appealed $2{\sim}3$ cases for the latest 1 week. Owing to subjective symptom, 54.95% drop into hospital or pharmacy, 10.32% made temporary retirement or absence, 7.99% transferred into more comfortable duty and $39.4{\sim}54%$ experienced one or more managing mentioned above. 5. Fulfillment of health promotion life style of subjects was evaluated on full mark of 4.0 and total score was 2.63. Average mark of each area was personal relationship (3.05), self-realization (2.92), stress management (2.63), health control (2.48), physical exercise (2.19) and nutrition management (2.19) and personal relationship was highest and physical exercise and nutrition management were lowest. As general characteristics influencing health promotion life style, gender, residence style and employment period showed significant difference. Male showed higher mark than female and showed higher mark in order of own house, others, lease on deposit base, monthly rent. Subjects with longer employment period showed higher mark with significant difference. 6. Accounting of factor influencing each area of health promotion life style, self-realization showed significance in marriage status, income, residence style and education level and health control in age, residence style and employment period. Physical exercise showed significant difference in gender, age, residence style and employment period and nutrition in gender, age, residence style and employment period. Stress management showed significant difference in residence style and employment period and however not in personal relationship. 7. Health promotion life style relating with existence and kind of pain showed significant difference in all area except personal relationship area. In absence of pain, there was statistically significant high score in all area even in total health promotion life style and all area. Accounting of kind of pain, cases of $1{\sim}2$ kinds of pain and $5{\sim}6$ kinds of pain showed relatively high score and it was lower than mark of subject stated absence of pain. 8. Subjects appeal symptom were classified by symptom region and difference of total and each areas were evaluated. General area (p=0.002), self-realization (p=0.012), health management (p=0.023), physical exercise (p=0.028), nutrition management (p=0.028) and stress control (p=0.001) showed statistically significant difference and not in personal relationship area. Especially, elbow, shoulder and neck area marked high and group appealed pain of knee, arm and elbow, foot and ankle marked low. Based on those results, subjective symptom should be accounted seriously in diagnosis of occupational musculoskeletal disease of laborer and among subjective symptom, general characteristics of gender, age, condition of living, education level and employment period make effect. Generally subject appeal symptom marked lower than subject without symptom appeal and it means that life management of subject appealing musculoskeletal pain make important role in management and treatment of occupational musculoskeletal disease.
