This study was designed to identify the performance of occupational health services of 37 industries located in Kyung in area. The data was collected by a structured questionnaire developed by the Academic society of Community Nursing. This analysis had two factors, one was related to six of the industries, and the other was the actual assignment procedures of the health team members. This study was undertaken from December 4, 1992 to January 21, 1993. The results of the study were as follows: 1. The study group was primarily manufacturing industries which employed 300-1,000 employees. 2. The actual assignment state of occupation health team members with the exception of nurses was not kept to the regulations of the industrial safety health law. 3. The following was the analysis of the performance of occupational health services with two factors: 1). The larger the size of the six industries, the more the performance of health education, health assessment, and health screening. 2) The actual. practice of occupational health team members working environmental measurement, was more frequently performed by a nurse other than health team members together. 4. 1) The subscription rate of the laborers for primary health screening was 94%, and of these 10% had the need of secondary health screening. As a results of the secondary health screening the degrees were 'A' 45%, 'C' 92%, 'R' 21%. Of these degrees 'C', 'R' 4% were follow up cases. 2) 43% of laborers needed special health screening and .of these the subscription rate was 99%. The main item of the special health screening was physical factors. After the special health screening 46% required .follow up, 30% required medical treatment, only reporting 18%, change work 8%, suspension from work place 2%.

This paper sought to help north Korean women understand their lives and seek to integrate the in-house between North and South Korea by organizing the overall reality of north Korea's fashionable hairstyles and beauty industry. The research method looks at the appearance management activities of North Koreans in north Korean media, media outlets, and testimonies of north Koreans who have been on the outstay since Kim Jong-un's ruling, among other things, and analyzed their hair activities. C. Studies have shown that some improvements have been made since the Kim Regime through the smuggling of foreign goods by yusists. In addition, it was confirmed that beauty education is being systematically edied out through a beauty training institute in North Korea, and that it has changed from a fixed salary system to an ability-based allowance. This study shows a limitation that north Korea has failed to study. It is believed to be a boon to future research on North Korean hair.

This study was conducted to examine the academic stress, menstrual attitude, and dysmenorrhea of adolescents and to understand their effects on dysmenorrhea. The subjects of the study were high school girls and 131 people who agreed to participate in the study were analyzed. Correlation analysis shows that the more negative the person is about menstruation, the more severe the physical symptoms, the more active the action, and the greater the emotional change, the more severe the person experienced dysmenorrhea. Factors affecting dysmenorrhea in adolescents were physical symptoms and positive acceptance among menstrual attitudes, and 68.8 percent explained the variable. In conclusion, considering the positive acceptance of menstruation and physical symptoms of adolescents, it is necessary to develop educational programs that provide integrated knowledge to manage dysmenorrhea in school health, and further individual and multidimensional approaches such as emotional support programs for negatively experienced emotions.

With the shortage of labor force in small and medium-size industries, the Korean Employment Permit System (EPS) continues to bring migrant workers. However, the question remains of the health and safety management of their migrant workers. Considering that a significant part of safety and health problems are caused by migrant workers due to a lack of information on identifying risk and inexperience in the field. Telephone interviews were conducted to investigate the migrant workers' perspectives on workplace safety practices. The survey focused on workers' accident histories, understanding of safety practices, and responding to industrial accidents. A total of 66 accidents occurred among 30 participants. 10 accidents were not reported to the employer (company), which the foreign workers judged to be minor injuries that should not be reported as accidents. 80.0% of the participants expressed dissatisfaction with the PPE they were using. Among various reasons lack of understanding due to language barriers, lack of awareness of the importance of safety, communication difficulties were major reasons for the caused accidents and potential health issues. It is necessary to improve the safety and health support system by providing practical support through specialized educational institutes with experts in the field. A legal framework and a proper safety management system need to be maintained. This study suggests changing the current policy to improve the health and safety of migrant workers by, establishing specialized educational institutes with locally grown foreign experts in the field.

The study aims to comprehend the health needs of multicultural families, identify relevant policies, and explore ways to enhance health information accessibility through Information and Communication Technology (ICT). Employing a qualitative research method, the health status of multicultural families was analyzed through literature review, followed by in-depth interviews. The findings revealed a lower priority given to health policies for multicultural families compared to other governmental sectors, with limited discussion on leveraging ICT for improved accessibility. In-depth interviews highlighted four main themes: "Early experiences in Korean society," "Language barriers in medical facilities," "Unmet healthcare needs for various reasons," and "High demand for health-related services." To safeguard health rights and enhance information accessibility, we recommend strengthening linguistic support in healthcare institutions, implementing government efforts for multicultural families, and designing user-centered ICT platforms.

Objectives: Operators of overhead traveling crane in a ship assembly factory perform work to transmit large vessel blocks to an appropriate working process. Hazardous matters such as metal dusts, carbon monoxide, carbon dioxide, ozone, loud noise and fine particles are generated by variable working activities in the factory. The operators could be exposed to the hazardous matters during the work. In particular, welding fumes comprised of ultra fine particles and heavy metals is extremely hazardous for humans when exposing a pulmonary through respiratory pathway. Occupational lung diseases related to welding fumes are increasingly on an upward tendency. Therefore, the objective of this study is to assess properly unknown occupational exposure to the welding fumes among the operators. Methods: This study intended to clearly determine an equivalence check whether or not chemical constituents and composition of the dusts, which existed in the driver's cab, matched up with generally known welding fumes. Furthermore, computational fluid dynamics program(CFD) was used to identify a ventilation assessment in respect of a contamination distribution of welding fumes in the air. The operators were investigated to assess personal exposure levels of welding fumes and respirable particulate. Results: The dust in an operation room were the same constituents and composition as welding fumes. Welding fumes, which caused by the welding in a floor of the factory, arose with an ascending air current up to a roof and then stayed for a long time. They were considered to be exposed to the welding fumes in the operation room. The personal exposure levels of welding fumes and respirable particulate were 0.159(n=8, range=0.073-0.410) $mg/m^3$ and 0.138(n=8, range=0.087-0.178) $mg/m^3$, respectively. They were lower than a threshold limit value level($5mg/m^3$) of welding fumes. Conclusions: These findings indicate that an occupational exposure to welding fumes can exist among the operators. Consequently, we need to be keeping the operators under a constant assessment in the operator process of overhead traveling crane.

Objectives: The purpose of this study was to investigate the status of asbestos-containing materials (ACMs) used on ships and to consider measures for preventing worker exposure to asbestos fibers. Methods: A total of 17 ships including 16 ships under repair and a ship under construction at shipyards in Korea were investigated. Bulk samples were collected from suspected ACMs on engine exhaust pipes, boiler steam pipes, generator exhaust pipes, and etc. in ships in order to identify the presence of ACMs. Types and contents of asbestos were determined using polarized light microscopy (PLM). Results: ACMs were found from 14 ships out of 17 ships investigated. Only chrysotile asbestos was found from all samples. ACMs were mainly found from samples collected at the exhaust pipes of the engine, generator and incinerator, and boiler steam pipes where exhaust gases or steam of high temperature pass through. In most cases, types of ACMs were asbestos-containing fabrics such as asbestos tape. Friable ACMs were also found in some cases. Use of ACMs on ships was relevant to built time and owner of the ships rather than type and tonnage of the ships. Conclusions: ACMs were found from most ships built prior to 2000s. Therefore, measures for preventing asbestos-related diseases such as preparation of asbestos map on the ship and installation of warning signs, hazard communication with workers (ship-repairing workers, engine room workers and etc.), and follow-up for worker's health management are needed.

The objective of the survey is to define and judge exposure profiles semi-qualitative data in high risk processes using styrene. The survey was conducted on 98 factories out of 229 factories based on data from periodic working environment monitoring for styrene. Styrene is widely utilized as a raw material for PS and co-polymers such as ABS, SAN, SBR, SBL, unsaturated polyester resins(UPR) and others. An approximate breakdown of styrene's markets in Korea is PS 30%, expandable PS 17%, ABS 33%, SAN 5%, SBL 4%, SBR 3%, UPR 1% and other 7%. Although UPR accounts for 1% of total amount of styrene, workers dealing with it are exposed to very high concentrations up to 64 ppm. Especially styrene is widely used in the laminating process of fiberglass reinforced plastics(FRP) manufacturing industry. The Applications using styrene are largely classified into two sections which are applied to styrene monomer(SM) and UPR. SM is utilized for a raw material of resins, surfactant and adhesive. UPR is employed for FRP and non-FRP. For SM control targets are mixing colors and packing in the gelcoat resins manufacturing industry(MI), for UPR control targets out of works using UPR are 1) laminating in the MI of plastics, automobile parts and boats, 2) mixing and packing in the SMC/BMC MI, 3) molding and cutting in the other specific plastics MI, 4) mixing and coating in artificial marble product MI, 5) dipping in the electric motors & transformers MI, 6) molding in the button MI, 7) painting in the musical instrument MI. Findings from the study have given the information for the high risk processes and working practices so that occupational health professionals could focus on targeted workplaces to prevent occupational diseases. It is also useful to develop a control strategies and specific controls for high risk processes and facilities using styrene.

Objectives: This study was aimed at the examination of the lead exposure status of smelting process workers in steelmaking using scrap iron. Methods: The study was conducted from July to September 2012 by means of measurements taken during the smelting process, with 45 minutes set for a one-time smelting work cycle when it comes to personal air sample and area air sample. As such, daily work hours were classified into 360 minutes for measurement. The analysis of lead concentration was conducted using AAs based on the NIOSH 7300 method. Results: In the case of the personal specimens that were subjected to periodical measurement 45 minutes per one session during the smelting process, 40 out of 42 specimens measured were found to contain lead, with an average concentration level of $0.028mg/m^3$ (Max: $0.182mg/m^3$, Min: $0.005mg/m^3$, TWA-more than 50%: 4 out of 6 units). In the case of regional specimens, lead was detected in 45 out of 48 specimens measured, with an average concentration level of $0.037mg/m^3$ (Max: $0.220mg/m^3$, Min: $0.007mg/m^3$ ). In the case of regional specimens subjected to measurement using a day as the work cycle, lead was detected in 15 out of 15 specimens measured, with an average concentration level of $0.049mg/m^3$ (Max: $0.478mg/m^3$, Min: $0.005mg/m^3$ ). Conclusions: It concluded that smelting process workers in steelmaking are exposed to lead because scrap iron is used as a raw material. It is thus necessary to introduce legal management to prevent occupation-related disease in smelting process workers in steelmaking.

Objectives : The purposes of this study were to evaluate exhaust ventilation systems(EVSs) and to suggest problems and improvements. Methods : For 50 small and medium-sized enterprises, we carried out evaluation of EVSs. We evaluated hoods with smoke tester and measurement of capture velocity. In addition, we used several indicators for performance evaluation designed in this study. Results : 1. Based on the smoke flow pattern and the criteria of occupational health and safety act, 67.8% of hoods were rated 'good' level at smoke test whereas 26.3% were rated 'good' level at measurement of capture velocity. 2. 29.3% of hoods, of which ratio of measured actual air flow at hood(Qah) to required ideal exhaust air flow at hood(Qih) was 1 or more, were rated 'good' level. 3. The % of EVS, of which ratio of measured actual air flow at stack(Qast) to total required ideal exhaust air flow at hood(Qith) was 1 or more, was 29.0%. 4. For the ratio of measured Qast to existing air flow at fan(Qfan), only 5% of EVSs were 1 or more and 26.0% were 0.8 or more but less than 1.0. 5. For the ratio of measured Qast to total measured actual exhaust air flow at hood(Qath), 74.0% were 0.8 or more but less than 1.0. 6. The percentage of EVS, of which ratio of total measured Qath to existing Qfan was 0.8 or more, was 19.0%. 7. The percentage of EVS, of which ratio of total measured Qath to total required ideal exhaust Qith was 1 or more, was 26.0%. 8. For the comprehensive evaluation indicators designed in this study, 29.0% were 0.8 or more. Conclusions : We found that few exhaust local ventilations at small and medium-sized enterprises were rated 'good' level and that most exhaust local ventilations had 'poor' design and installation. Therefore, relevant professional manpower and enterprises have to construct exhaust local ventilation where it is needed, and technical guidance and economic support are needed to improve 'poor' exhaust local ventilation after self-evaluation.
