Historically, women's health needs have been viewed primarily as reproductive, and all other health needs have been dealth with without considering their responses to disease and treatment(Strickland & Giger, 1994). It has mostly been through the efforts of women's group, especially health care team, that more recognition has been given to the overall health of women worker in recent years. The purpose of this study was to examine the depression, self-esteem and health practice in order to identify health care strategies to improve health promotion among women workers in small workplace. The consisted of 94 women workers who work at small manufacturing industry. The data were collected from January to February, 2002. The instruments for this study was Rogenburgs self-esteem scale, Zung s depression self-reporting scale and Breslow & Enstrom s health habits scale. The analysis of data were performed with frequency, percentage, t-test, ANOVA. $\chi^2$ test, pearson correlation and multiple regression using SPSS Win 10.1 program. 1. The average depression score was 1.87 which is relatively low and the average self-esteem score was 2.75 which is relatively moderate. The total mean score for health practice was 4. 10(range 0-7) which is relatively high moderately. 2. Health practice had not a statistically significant correlation with depression and self-esteem, but the depression had a statistically significant correlation with self-esteem(r=-.401, p=.000). 3. There was not a significant difference In depression, self-esteem and health practice according to the general characteristics 4. There was a significant difference in sub category of health practice according to the status of living with family and status of marriage. As far as the health practice of women workers living with family practiced better health than women workers no living with family concerning breakfast(p=.03) and as far as the health practice of women workers no living with family practiced better health than women workers living with family concerning sleeping time(p=.04). There was a significant difference in breakfast(p=.04), smoking(p=.00), and BMI(p=.05) according to the status of marriage. 5. The major factor was age and explained for $7\%$ of health practice. The repeated study should be carried out to figure out the health practice and its related factors of female workers at small manufacturing industry.

This study was performed to find out the exposure level of mixed organic solvents, excretion of urinary hippuricacid and subjective symptoms according to the exposure of organic solvents of female workers who works on 5 shoes manufacturing industries in Taejon City from 24, september to 20, october 1993. The studied groups were divided into 3 groups that were consist of direct exposure group(48 workers), indirect exposure group(49 workers) and non-exposure group(68 workers) to the organic solvents. The exposure levels of toluene of direct exposure group which $89.86{\pm}56.20ppm$ had higher than that of indirect exposure group which had $40.23{\pm}47.21ppm$. In the exposure level of mixed organic solvent(R-value), direct exposure group was $2.84{\pm}1.53$ and exceeded approximatly 3 times the R-value. Whereas, indirect exposure group was not exceeded the R-value as $0.80{\pm}0.61$. In the excretion level of urinary hippuric acid, direct exposure group was $1.78{\pm}1.25g/l$, indirect exposure group was $1.22{\pm}0.93g/l$ and non-exposure group was $0.51{\pm}0.18g/l$ respectively. Therefore both direct exposure group and indirect exposure group were significantly higher than non-exposure group(P<0.01). In the correlation between toluene levels and urinary hippuric acid level, the direct exposure group had positive correlation(R=0.8309, P<0.01), also indirect exposure group had positive correlation(R=0.5859, P<0.05) and also in the correlation between the R value of mixed organic solvents and the urinary hippuric acid levels, the direct exposure group had positive correlation(R=0.4492, P<0.05), and indirect exposure group had ositive correlation(R=0.7911, P<0.01). In the complain rates of the worker's subjective symptoms at work, both direct exposure group and indirect exposure group were higher than non-exposure group(P<0.05, P<0.01). But the sujective symptoms of "floating sensation" of direct exposure group had significantly higher than indirect exposure group. In the percent of subjective symptoms complaints during the worker's daily life, both direct exposure group and indirect exposure group had generally more statistical significance than nonexposure group(P<0.01), direct exposure group had not statistical significant difference from indirect exposure group. As the results mentioned above, it has been analysed that the indirect at the adjacent manufaturing process are exposed to the considerable amount of solvent. Therefore, I think that there should be the betterment of surrounding through the complete working environment management to the occurrence source of the organic solvent, the changes of health management system to the indirect-exposed workers, and the systematic management of the special medical examination and the like.

Background: The European Centre for Ecotoxicology and Toxicology of Chemicals' Targeted Risk Assessment (ECETOC TRA) tool has been recognized by EU REACH as a preferred approach for calculating worker health risks from chemicals. Objectives: The applicability of the ECETOC TRA to occupational exposure estimation from industrial uses of methanol was studied by inputting surveyed and varied parameters for TRA estimation as well as through comparison with measured data. Methods: Information on uses of methanol was collected from seven working environment monitoring reports along with the measured exposure data. Input parameters for TRA estimation such as operating conditions (OCs), risk management measures (RMMs) and process categories (PROCs) were surveyed. To compare with measured exposures, parameters from the surveyed conditions of ventilation but no use of respiratory protection were applied. Results: PROCs 4, 5, 8a, 10, and 15 were assigned to ten uses of methanol. The uses include as a solvent for manufacturing sun cream, surfactants, dyestuffs, films and adhesives. Methanol was also used as a component in a release agent, hardening media and mold wash for cast products as well as a component of hard-coating solution and a viscosity-controlling agent for manufacturing glass lenses. PROC 8a and PROC 10 of a cast product manufacturer without LEV (local exhaust ventilation) and general ventilation as well as no respiratory protection resulted in the highest exposure to methanol. Assuming the identical worst OCs and RMMs for all uses, exposures from PROC 5, 8a, and 10 were the same and the highest followed by PROC 4 and 15. The estimation resulted in higher exposures in nine uses except one use where measured exposure approximated exposures without RMMs. Conclusions: The role of ECETOC TRA as a conservative exposure assessment tool was confirmed by comparison with measured data. Moreover, it can guide which RMMs should be applied for the safe use of methanol.

도시산업구조의 진단과 예측은 지속가능한 도시발전계획수립을 위한 주요한 과제이다. 지금까지의 산업관련 도시공간구조 연구들은 주로 도시산업체 자료나 총 종사자수 자료를 활용하여 산업유형별 공간분포의 측정에 집중되어져 왔다. 그러나 최근 비정규직 문제를 포함한 근로자의 종사상 지위가 중요한 이슈가 되는 시점에서 본 연구는 읍면동 단위의 1994년 및 2004년 종사상 지위별 자료를 수집하고 동 변화자료를 기반으로 공간분석 단위를 일치시킨 후 GIS를 활용하여 종사상 지위분류체계 자료를 활용한 도시산업구조의 질적 변화를 공간적 관점에서 해석하였다. GIS환경에서 부산시 산업구조의 종사상지위 유형별 분석 결과는 다음과 같다. 첫째, 전통적인 노동집약적 산업이 한계에 부딪히고, 서비스업 및 도소매업은 영세한 생계형으로 진행되어 부산의 고용흡수력이 떨어질 수밖에 없었으며 통계상으로는 종사자의 수가 증가하였으나 비정규직과 비임금 노동자가 급증하면서 부산지역 일자리의 질이 하락하고 있는 것으로 측정되었다. 둘째, 전통적인 도심지는 쇠퇴하는 반면 신도시나 신흥공업단지가 형성된 지역, 제조업보다 서비스업이 발달한 지역이 일자리가 증가하는 경향을 보였다. 본 연구의 결과는 도시발전의 근간이 되는 산업구조의 행태적 패턴 뿐 아니라 종사상지위라는 질적 평가를 통한 장기적 차원의 산업발전계획안 마련을 위한 기초자료로서의 활용을 기대한다.

This study was conducted to investigate the kinds of health promotion program which workers want, worker's intention for participation, proper method, time, duration and manager. A self-administered questionnaire method was used to collect data from 412 employees of 3 worksites in Chungpook and Kyungkee. This survey was carried out from Aug. 10 to Aug. 20, 1998. The results of this study are as follows: 1. In male, among health promotion programs, favorite ones were physical fitness(32.2%), periodic health check-up(24.6%), and stress management(18.0%). In female, among health promotion programs, favorite ones were periodic health check-up(26.0%), physical fitness(22.0%), and body weight control(19.5%). 2. The more young subjects are, the more they like physical fitness program, and the female like body weight control program regardless of BMI. Manufacturing worker preferred back pain prevention program to clerical worker did. In female, drinker preferred stress management program to non-drinker did. 3. The more old subjects are, the more they like back pain prevention program, and non-smoker preferred body weight control program to smoker did. 4. In health promotion program format which the subjects wanted, learning of self-examination techniques was 41.1%, worksite screening was 3l.0%, availability of pamphlets and audiovisual materials was 20.0%, presentation of worksite educational sessions was 7.9%, and the most wanted manager for the program was medical doctor and then nurse, physical trainer, psychological counselor. The favorite health promotion program duration was less than 30 minutes(49.6%), and the favorite time was before work(49.6%). 5. Among respondents, 48.5% was smokers, 81.8% was drinkers, 39.9% engaged in the regular exercise, 68.2% engaged in regular diet habit. In vaccination, 50.2%, if possible, wanted to be vaccinated and 37.6% never wanted to be vaccinated. 6. Ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit responded they were in good health. There was a significant difference between exercise and health status. Need and intention for participation of health promotion program were high in ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit. According to results for this study, if the favorite programs, exercise, periodic health check-up, stress management program, are operated at a proper time and with managers they want, this programs can really raise the participation of employees. And as employees want to learn self-examination techniques if worksite educational sessions are performed, health promotion program can effectively be operated.

The purpose of this study is to understand women's wear manufacturing industries. First, the study was to investigate the present production systems and how much the automatic facility are by comparing them. This study enhanced more efficient, stable, and suitable work line. This intern will direct the way in which automatic facilities will be created. Second, through this study on the general character of the inspectors, the ratio of impaired goods, and the reasons for unsatisfactory goods, I intended to find out a way to decrease the impaired goods and to produce competitive and high quality goods. The results of the survey can be summarized as follows; 1. The result of the research on the automatic industrial facilities shows that the majority of the factories (77.4%) are 40% below the automatic facility rate. The reasons for this according to order are that was a deficit in money, no reason for expensive machines, and lack of the technique and the number of workers required to handle the machines. 2. At this time, the most required equipments are shown according to its importance; automatic sewing machine, automatic cutting machine, automatic spreading machine, and finishing & pressing machine. So in the women's wear manufacturing industries, they think that they need more automatic cutting machine, automatic spreading machine in the cutting field rather than high price automatic machine in the sewing field such as pattern former, pocket welting, automatic sleeve connecting machine and automatic label connecting machine. 3. The result of the research in the goods quality shows that the average impaired rate is 12.7% at the first inspection. In addition the average rate for complete impaired rate is 1.52%. The line system shows that it has a impaired rate that is double the rate of the pair system. Because of this, the industries plan to combine the line system and pair system to create an improved and suitable production system which can boost the quality and productivity of the goods. 4. The fabric is the main point of the impaired goods. The factors of the impaired goods in manufacturing are the lack of mental abilities of the worker, impaired fabrics and a lack of cooperation in the working system. Furthermore, there is a lack of technique for new material. 5. To prohibit impaired goods in manufacturing, there need to be a way to educate the workers and to enhance the workers' mind on the productive goods. Also there need to increase in the investments of automatic production machines. Finally there need to be a standardized working line. Therefore, there need to be an improvement on the management of the production of goods, the development of technique and an increase in the education for the workers, with this there will be a decrease in impaired goods, and an increase in better quality of goods to enforce the domestic apparel industries.

Objectives: The aim of this study is to evaluate exposure levels of the extremely low frequency magnetic fields(ELF-MF) radiated from various electric facilities in Liquid Crystal Display(LCD) manufacturing processes. Methods: This study measured the exposure levels of personal and local ELF-MF for the electronic facilities installed in two LCD manufacturing companies. Samplers were installed around workers' waist during working hours to identify personal exposure levels, and direct reading equipment were located at 3 cm, 10 cm, and 30 cm away from the surface of the electronic facilities to measure local exposure levels. Average and maximum(ceiling) values were calculated for personal and local exposure levels. Results: Average and maximum of personal exposure levels for each worker were 0.56(mean) ± 0.02(SE) µT and 6.31 ± 0.75 µT, respectively. Statistical analyses of the study found that maximum of the personal exposure levels for engineers was significantly higher than that for operators since engineers spend more time near the electronic facilities for repairing. The range of maximum personal exposure levels was 0.50 ~ 43.50 µT and its highest level was equivalent to 4.35 % of ACGIH(American Conference of Governmental Industrial Hygienists) exposure limit value(1 mT). Maximum of local exposure levels was 8.18 ± 0.52 µT and the electronic facilities with higher exposure levels were roof rail and electric panel, which were not related to direct manufacturing. The range of maximum local exposure levels was 0.60 ~ 287.20 µT and its highest level was equivalent to 28.7 % of the ACGIH exposure limit value. Lastly, the local exposure levels significantly decreased as the measurement distance from the electronic facilities increased. Conclusions: Maximum of personal and local exposure levels did not exceed the exposure limit value of ACGIH. However, it is recommended to keep the workers as far as possible from the sources of ELF-MF.

Recently, an electricity sensor system has been installed and operated to prevent failures and accidents by identifying whether a transformer is normal in advance of failure. This electricity sensor system is able to both measure and monitor the transformer's power and voltage remotely and send information to a manager when unusual operation is discovered. However, a battery is required to operate power detection devices, and battery systems need ongoing management such as regular replacement. In addition, at a maintenance cost, occasional human resources and worker safety problems arise. Accordingly, we apply a linear electromagnetic generator using vibration energy from a transformer for an electric sensor system's drive in this research and we conduct optimal design to maximize the linear electromagnetic generator's power. We consider design variables using the provided design method from Process Integration, Automation, and Optimization (PIAnO), which is common tool from process integration and design optimization (PIDO). In addition, we analyze the experiment point from the design of the experiments using "MAXWELL," which is a common electromagnet analysis program. We then create an approximate model and conduct accuracy verification. Finally, we determine the optimal model that generates the maximum power using the proven approximate kriging model and evolutionary optimization algorithm, which we then confirm via simulation.
