  • This study analyzes the impact of occupational health risk assessments on the safety and health levels and the safety behaviors of workers in manufacturing workplaces. An online survey was conducted among 3,172 companies, yielding 637 responses. The statistical analysis on the collected responses revealed three key findings. First, the safety and health levels (safety importance, safety comprehension, safety awareness) positively influence the outcomes of occupational health risk assessments(safety practice, safety management, safety improvement) and safety behaviors (activity change, safety check). Second, the effectiveness of occupational health risk assessments has a positive impact on safety behaviors. Lastly, the effectiveness of occupational health risk assessments partially mediate the relationship between safety and health levels and safety behaviors. These findings are expected to contribute to the promotion of risk assessments in the field of industrial health and to enhancing safety performance by improving workplace safety, health levels, and safety behavior.

  • Purpose: This study was constructed in order to examine factors that influence work-related musculoskeletal disease (WMSD) approvals and current status according to the company size. Method: This is a descriptive study that utilized Industrial Accident Compensation Claim Data. Workplaces with over 35,811 workers derived from the 2012 claim data, which comprised approximately 91.5%, were selected for this study. Then workplaces were divided into three groups according to the number of workers: less than 5, 5~299, and 300 and over. Results: Since 2008, the number of small sized workplaces has increased. The 2012 data showed that 32.5% of workers at small sized workplace had WMSD. However, workplaces with 5~299 workers showed WMSD approval rate of 60%. Of note most WMSD approved workers were employed by manufacturing and construction companies, regardless of the workplace size. Most of them were engaged in elementary tasks. The days of medical treatment at OPD and IPD were most prevalent among workers at the largest workplaces. Conclusions: It is certain from this study that WMSD has been polarized by the company size. More policy attention should be paid to the WMSD status of workers at small sized workplaces which usually do not have their own health office.

  • This paper is written following an analysis of occurrence trend of industrial disaster in manufacturing industry. One of major reason of industrial accident is unsafe action caused by lack of work supervision. so we have surveyed the understanding level of supervisors for industrial safety and their education of industrial safety which is forced by industrial law. We have got the result that the supervisor's education is necessary to prevent industrial disaster but it's not fit for their own workplace for various reasons from the survey and analysis. I would like to suggest effective solutions. The institute of education should train that they can execute safety and health works themselves by classification of the industrial category, company scale and located region. Also, government should endow supervisors with authority and responsibility for the activation of education system. Finally, government should support the expense of education to medium and small-sized enterprises especially, and they should be interested in the attendance and execution of education. They will achieve the goal to prevent industrial disasters in manufacturing industry through the enforcement of effective supervisor system as per the remark mentioned above.

  • The aerosol nanoparticles are suspected to be exposed to workers in nanomaterial manufacturing facilities. However, the exposure assessment method has not been established. One of important issues is to characterize background level of nanoparticles in workplaces. In this study, intensive aerosol measurements were made at a $TiO_2$ manufacturing laboratory for five consecutive days in May of 2010. The $TiO_2$ nanoparticles were manufactured by the thermal-condensation process in a heated tube furnace. The particle number size distribution was measured using a scanning mobility particle sizer every 5 min, in order to detect particles ranging from 14.5 to 664 nm in diameter. Total particle number concentration shows a severe diurnal variation irrespective of manufacturing process, which was governed by nanoparticles smaller than 50 nm in diameter. During the background monitoring periods, significant peak concentrations were observed between 2 p.m. and 3 p.m. due to the infiltration of secondary aerosol particles formed by photochemical smog. Although significant increase in nanoparticle concentration was also observed during the manufacturing process twice among three times, these particle peak concentrations were lower than those observed during the background measurement. It is suggested that the investigation of background particle contamination is needed prior to conducting main exposure assessment in nanomaterial manufacturing workplaces or laboratories.

  • 지구온난화로 인하여 태양광 발전에 대한 관심이 커지고 있다. 이에 따라 태양전지를 만드는 핵심물질인 폴리실리콘의 수요도 나날이 증가하고 있으며 시장이 커짐에 따라 생산공정에서 크고 작은 사고들이 발생하고 있다. 그 예로 2013년 상주시의 폴리실리콘 제조공장에서 염산이 누출되었고 2014년에는 여수시의 폴리실리콘 제조공장에서 화재가 발생하였으며, 2015년에는 군산시의 폴리실리콘 제조공장에서 STC(Silicon Tetrachloride)가 누출되었다. 이러한 누출 사고들은 사업장 내부에만 영향을 주는 것이 아니라 인근지역까지 영향을 줄 수 있다는 것이 특징이다. 따라서 본 연구에서는 폴리실리콘 제조공정에서 사용되는 위험물질을 파악하고, 최악의 누출 시나리오를 적용했을 때 누출량과 피해범위를 정량적으로 예측하였다. 그 결과 폭발에 따른 피해거리는 726 m로 예측되었고, 독성에 대한 피해거리는 4,500 m로 예측되었다. 그리고 TCS(Trichlorosilane), STC(Silicon Tetrachloride), DCS(Dichlorosilane)가 누출되어 공기 중의 수분과 반응하여 HCl이 생성될 경우 피해거리는 최대 5.7 km까지로 예측되었다.

  • Objectives: The purpose of this study was to investigate types and characteristics of chemical substances used in LCD(Liquid crystal display) panel manufacturing process. Methods: The LCD panel manufacturing process is divided into the fabrication(fab) process and module process. The use of chemical substances by process was investigated at four fab processes and two module processes at two domestic TFT-LCD(Thin film transistor-Liquid crystal display) panel manufacturing sites. Results: LCD panels are manufactured through various unit processes such as sputtering, chemical vapor deposition(CVD), etching, and photolithography, and a range of chemicals are used in each process. Metal target materials including copper, aluminum, and indium tin oxide are used in the sputtering process, and gaseous materials such as phosphine, silane, and chlorine are used in CVD and dry etching processes. Inorganic acids such as hydrofluoric acid, nitric acid and sulfuric acid are used in wet etching process, and photoresist and developer are used in photolithography process. Chemical substances for the alignment of liquid crystal, such as polyimides, liquid crystals, and sealants are used in a liquid crystal process. Adhesives and hardeners for adhesion of driver IC and printed circuit board(PCB) to the LCD panel are used in the module process. Conclusions: LCD panels are produced through dozens of unit processes using various types of chemical substances in clean room facilities. Hazardous substances such as organic solvents, reactive gases, irritants, and toxic substances are used in the manufacturing processes, but periodic workplace monitoring applies only to certain chemical substances by law. Therefore, efforts should be made to minimize worker exposure to chemical substances used in LCD panel manufacturing process.

  • 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.

  • Objectives: The purpose of this study is to analyze the occupational safety and health(OSH) state of precarious employee. Methods: The questionnaire of this survey is composed of 9 categories that are the workplace general information and the state of occupational injury and disease, OSH organization, OSH education and training. The subjects of this survey were the Manufacturing. The hypothesis of this study is where the proportion of precarious employee is higher, the OSH state is worse. To verify this hypothesis, we grouped the subjects into three categories by the proportion of precarious employee like as 0%(all standard employee), less than 30% and 30% or more. Using the SPSS 12.0 program to analyze the data, logistic regression analysis were implemented to find affective factors for the rate of occupational injury and disease. Results: 2,633 manufacturing workplaces were included for subjects. The proportions of precarious employee were 9.6 %. In manufacturing industry, about 70 % companies had no precarious employee. 16.8 % companies were in less than 30 % group, 13.2 % companies were in 30% or more group. For the rate of occupational injury and disease, the precarious group were 0.85(${\pm}1.8$), 1.19(${\pm}2.9$), 0.59(${\pm}1.1$). There was a trend that the higher precarious proportion groups was the higher rate of occupational injury and disease by the logistic regression analysis. It is more strong relationship than company size and OSH committee. Conclusions: We could find a significant result there was a positive relationship between the hiring proportion of precarious employee and the rate of occupational injury and disease in manufacturing industry with 50 employees and more.
