This study was conducted to evaluate the degree of stress state and the risk factors related to in 967 white collar workers and 275 blue collar workers by using Psycosocial Well-being Index. The results obtained were as follows : 1. In the white collar workers and blue collar workers, young age, low education and low income groups had high scores of stress, while in white collar workers, female had high scores of stress but in blue collar workers, male had high scores of stress. 2. According to psychosocial well-being index, mild stress sto were 73.9% and 53.1%, high risk stress state were 8.9% and 44.4%, and healthy state were 17.2% and 2.6% in white collar and blue collar workers respectively. 3. The total stress score was highly associated with the factors of depression, social performance and self-confidence, general well-being and vitality, and sleeping disturbance and anxiety in order. 4. In reliability test of stress factors, Cronbach's $\alpha$ coefficients of depression, social performance and self-confidence, general well-being and vitality, and sleeping disturbance and anxiety were 0.89, 0.81, 0.79, and 0.74 respectively. In conclusion, it suggested that age, sex, marital status, income, education, sleeping time, smoking and exercise habit were associated with stress score, all of the above factors should considered to occupational health.

The purpose of this study is to review previous domestic and foreign studies and to investigate personal work-life harmonization through theoretical research on familyfriendly management using a dual agenda approach. The authors briefly identified trends and critically reviewed domestic researches on family-friendly management and foreign studies of scholars that overcame the limitations of domestic studies to present a foundation for work-life harmonization through a dual agenda approach. As a result, the existing family-friendly management was found to be compatible with work and family but was not effective in developing personal careers. The workers who actively accepted family-friendly management as part of their work-life balance were mostly female laborers who were employed part-time, had lower academic education, earned lower wages and, in general, were non-professional workers without specific skills or career aspirations. The remainder of the workers, full-time male employees, with higher education and with professional knowledge and skills, inevitably worked longer, more labor-intensive hours, due to the advent of the dual agenda approach. A new work-life harmonization program is urgently needed not only for family-friendliness but also for healthy organizations, individual career development and personal wellbeing.

PURPOSE: This study examined the necessity of a musculoskeletal injury-prevention program for automobile parts manufacturing workers by assessing the body composition, muscle strength, and posture according to sex and age. METHODS: Two hundred eighty-two workers (men, 218; women, 64; mean age, 38.97 years; and mean work tenure, 10.29 years) participated in this study. They completed a questionnaire on their general characteristics, excluding personal identification codes. The participants were evaluated for body composition, muscle strength, and posture using InBody, a hand dynamometer, and the Image J program through photography, respectively. An independent t-test and one-way analysis of the variance were used for the comparisons according to sex and age, respectively. RESULTS: Significant sex-related differences in muscle strength and grip force were observed (p<.05). In addition, the left-side pelvic inclination was significantly higher in the female participants than in the male participants (p<.05). Significant age-related differences in the skeletal muscle mass and muscle strength were observed around 40 years (p<.05). Significant correlations were observed among the body composition (skeletal muscle and body fat masses), muscle strength, and posture (pelvic inclination; p<.01). CONCLUSION: Significant differences in pelvic inclination by sex and muscle strength by age were found, even in healthy workers. Additional posture and muscle strength measurements will be needed for workers who participate in the musculoskeletal injury prevention program because they are exposed to an incorrect posture for many hours or in many repetitive tasks.

The widespread use of VDU has improved the efficiency of information transmission between man and machine, but has caused new occupational health and ergonomics problems. In this study, we tried to construct a fuzzy hyman performance model of VDU workers in Korea. Fuzzy inferences of human perfor- mance are obtained from the fuzzy inference rule with the job difficulty, CFF, SACL, Type A. and the degree of concentration in VDU work. Eight healthy female undergraduate students at Kyungnam university for subjects aged 20 to 23 years were examined in this experiment. They calculated continuous addition, subtraction, and multiplication of 1 or 2 digit numbers that were produced randomly on the CRT. Subjects peoformed two types of a numeric operation, which easy and difficult work produced 400 and 600 problems within a 40 minute work session, respectively. Subjects were tested over two workdays according to the type of work(easy and difficult) consisting of four 40 minutes work sessions in the morning. Each work lasted for five minutes with a ten minutes rest break. 117 fuzzy inference rules were obtained from the experimental data. The value of consequent part was obtained by a descent method. The difference between real human error and estimated value of fuzzy inference was $1.8075{\pm}1.8591%(M{\pm}SD)$. The difference in easy and diffcult works were $2.69{\pm}2.13%$ and $0.92{\pm}0.93%$, respectively.

A survey on the nutritional state was conducted from June 11 to Nov. 30, 1971, on 673 women workers $(16{\sim}25\;yrs)$ Jorking in a factory of food industry. Total body fat content was measured by skin-fold thickness (S. F. T.) with caliper at three region of the body. And it was calculated by regression equation, with the following conclusions were abtained. 1. The mean with standard deviation body height and weight of the Korean women workers were $155.0{\pm}4.21\;cm$ and $50.1{\pm}5.31\;kg$; respectively. 2. Their mean skin-fold thickness with their standard deviation triceps region of upper arm, 14.3{\pm}3.42$; Subscapular region, $18.0{\pm}5.57mm$; Abdominal region, $19.3{\pm}4.87mm$ and total aveager, 17.2{\pm}3.91mm$. 3. The body fat contents according to body fat weight regression equation were;fat weight. 10.7 kg; fat-free weight, 39.4kg; fat weight/ fat-free weight, 27.5%; fat-free mass/ total body mass 77.6%, and fat weight/ total body mass,21.6%. 4. Since the sknin-fold thickness between the triceps and upper abdominal region and between the former and Subscapular region were correlated with the coefficients of 0.838 and 0.615 respectively. and the following regression equations were established. a) S. F. T. of Subscapular region $(mm)=0.929{\times}$S. F. T. of triceps region (mm)+4.707. b) S. F. T. of Abdominal $region(mm)=1.24{\times}$S. F. T. of triceps region(mm)+1.50. Nutritional survey on the women workers in a fact ory of food industry, performed as above by the S. F. T. method, elucidated the fact that their nutritional state is as good as the control healthy female, and that their energy uptake may well be said to be satisfactory.

This study divides female consumers according to eco-friendly attitudes and the purchase frequency of eco-clothing products; in addition, it analyzes the characteristics of each group in terms of LOHAS lifestyles, the attitudes for eco-clothing products, and satisfaction. Eco-clothing attitudes of female consumers were lower than eco-friendly attitudes. A total of 360 female consumers were divided into 4 group according to purchase frequency and the eco attitude, Type 1: survival (33.0%), Type 2: wellbeing (25.6%), Type 3: curious (15.0%), Type 4: LOHAS (26.4%); in addition, age, income, marit alstatus, occupation, LOHAS lifestyle and shopping places were differentiated by type. Type 1 (low eco attitude and low eco-clothing purchase) were composed of the youngest, college students, low income, low level of LOHAS lifestyles and low level of eco-clothing attitude. Type 2 (high eco attitude and low eco-clothing purchase) were interested in healthy eating & exercise among LOHAS lifestyles; in addition, Type 1 & 2 showed alow level of eco-clothing satisfaction. Type 3, low eco attitude and high eco-clothing purchase, were characterized with high expenditures on clothing relative to income as well as lower levels of family activities and leisure life than LOHAS Type 4. Type 4 (high eco attitude and high eco-clothing purchase) were the oldest group and mostly composed of married workers (the highest income) with the highest LOHAS lifestyles and the highest level of eco-clothing satisfaction.

The purpose of this study is to help female office workers in relieving their stress in rapidly changing modern society and maintaining a healthy and beautiful life by analyzing the complex effects of alternative beauty therapy on stress relaxation targeting 50 female office workers in their 30s to 40s, usually showing a high stress index due to their work. Aroma therapy and dry relax massage were carried out for 15 minutes as a beauty therapy, and stress index of the subjects was confirmed through survey before performing the beauty therapy. The experiment was conducted once a week for four weeks, and the cortisol concentration in saliva was analyzed for the outcome measurement. As a result, average stress index was 3.97 which showed a high value, and the cortisol concentration of the subjects after the experiment decreased significantly (p<0.05), and especially subjects who were married and had caregiving responsibility showed more changes in their cortisol concentration. The above result shows that dry relax massage using aroma is highly effective for mind and body relaxation of women in their 30s to 40s who are significantly stressed. If such beauty measures are applied properly, it is judged to be helpful for managing the stress.

The author investigated the zinc concentrations in sera of 110 methamphetaimine abusers (male 87, female 23) and of 41 healthy official workers(male 29, female 12) using inductively coupled plasma emission spectrometer. The serum zinc concentrations were analysed according to hepatitis C virus antibody(Anti HCV), hepatitis B surface antigen(HBsAg) and alanine aminotransferase(ALT) value in both groups. The analytical results were obtained as follows 1. The mean zinc concentration of MAP abuser group($298.5{\pm]246.9{\mu}g/100ml$) was 2.5 times higher than that of control group($118.8{\pm}25.4{\mu}g/100ml$). 2. The distributions of zinc concentration in both groups were skewed pattern. 3. The zinc concentrations were higher in Anti HCV-positive group and abnormal ALT value group than Anti HCV-negative group and normal ALT value group. But HBs-Ag positive group had lower zinc concentration than HBs-Ag negative group. 4. The number of anti HCV-positive subjects was increased and the zinc concentrations were decreasd in proportion to the abusing duration of MAP.

With increased use of neurotoxic agents in manufacturing industries, hazardous effects of neurotoxic agents pose significant problems in protecting health of workers who work in these industries. A normal range of neurobehavioral performance is required to study hazardous effects of neurotoxic agents among workers. However, such reference for Korean population is not available yet. The objective of this study is to estimate a normal range of neurobehavioral test performance of female workers in Korea. Data for neurobehavioral test performance developed by the World Health Organization were obtained from 165 female workers. Study subjects, 140 production workers and 25 clerks, who voluntarily participated in this study were not occupationally exposed to neurotoxic agents. The mean age and the mean education years of them were 32 years and 10.9 years, respectively Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention tests among the Neurobehavioral Core Test Battery(NCTB) were included in the evaluation. Subjects were interviewed by a trained interviewer for their detailed occupational history $Mean({\pm}SD)$ performance of the participants were: $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in the Santa Ana dexterity test of the preferred and non-preferred hands; $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in correct dot of the pursuit aiming test; $57.7{\pm}16.0$ in the digit symbol test; $274.8{\pm}44.6$ msec in the mean simple reaction time and $70.5{\pm}69.0$ msec in the mean standard deviation of it; and $7.8{\pm}1.7$ in the Benton visual retention test. Most neurobehavioral performance scores were correlated significantly with age and educational level. Educational level was found to be a significant independent variable which was associated with all test scores. Age was significantly associated with scores of pursuit aiming and digit symbol tests.

Background: Young male and female workers are over-represented in statistics concerning negative outcomes of poor work environment and risky work. Young workers often have low awareness of risk, a lack of safety training, and inadequate introduction to the work. The aim of this study was to identify the knowledge and experiences of pupils of vocational schools concerning potential work environment risks in their future work. Methods: The study design was a dual one, and included a questionnaire and focus group interviews. The study group consisted of 239 pupils from 10 upper secondary schools, who were graduating pupils in four vocational programs: the Industrial Technology Programme, the Restaurant Management and Food Programme, the Transport Programme, and the Handicraft Programme (in which students specialize in wood products). The upper secondary schools were located in the central region of Sweden. Results: The pupils had limited knowledge that employers must, by law, conduct risk analyses and prevent risks. Many felt that they themselves are mainly responsible for performing their tasks safely. Pupils in all programs mentioned acute risk as the greatest risk at work. The theoretical education about safety at work was provided in the $1^{st}$ year of the 3-year vocational programs. Conclusion: A systematic approach to pupils' training in work environment, which is a basis for a safe and healthy workplace, is lacking. The study findings indicate that pupils are offered knowledge far from that intended by laws and by state-of-the-art occupational health risk research.
