The modem industrial society is developing while growing more diverse and gigantic. Accordingly, occupational injuries or accidents can be caused in various situations, not just in the limited range of workplaces but also in the surroundings, and interest has increased in the prevention of occupational accidents with respect to occupational health and safety, and environment. Thus, this thesis will consider 4MlE (Man, Machine, Method, Material, Environment) as the fundamental causes of accidents and introduce a model of system in which the output of the process control system is replaced by accidents with its input by 4M1E. Furthermore, it will demonstrate how occupational hazardousness can be measured, whereby it can also be rated, by examining the relationship between 4M1E and types of accident in terms of the categories of severity, frequency, and detectability, based on the application of the model to the framework of FMEA.

Objective : This study used the data of the National Statistical Office to analyze the time use of disabled youth and their self-satisfaction with it by their type of occupation. Methods : Using raw data extracted from Statistics Korea, 84 disabled youth from 10 to 24 years old were re-classified into six occupational areas based on Occupational Therapy Practice Framework (OTPF)-3. The occupational types were classified according to the time use by individuals based on data from Statistics Korea. Finally, according to the type of occupation, self-satisfaction with the use of time was identified. Results : The total amount of time spent by disabled youths was the largest in the rest and sleep categories, followed by daily living, education, leisure, social participation, and play. The analysis of occupational types showed that the groups were turned around (10.71% of participants), high activity group (50.00%), low activity (28.57%), and balanced (10.71%). There were significant differences between types in the first five of the aforementioned categories. There was no significant difference in the lack of time use, but there was a significant difference among their satisfaction with their use of time. The balanced type (21.53%) reported the most satisfaction. inadequacy Conclusion : The purpose of the project was to provide the raw data of intervention activities that can improve the quality of life and health of disabled youth. By analyzing their time use and occupations, deficiencies in time management and their satisfaction with their use of time can be noted.

Objectives: In this study, we analyze statistics on industrial accidents caused by chemical skin contact and provide skin toxicity hazard information on the related domestic system and circulation volumes. Methods and Results: We analyzed occupational fatalities and skin diseases caused by chemical leaks and contact from 2007 to 2016(10 years) and surveyed data on occupational skin diseases using the 2014 work environment survey data. The NIOSH Skin Notation Profiles for 57 chemical substances, which are provided to prevent occupational skin diseases, were searched and hazard information on skin contact with chemical substances was classified. In order to identify skin toxicity information among domestically distributed and legally regulated substances and to investigate skin-toxic substances, MSDS basic data on 19,740 chemical substances provided on the homepage of Korea Occupational Safety & Health Agency were searched. Acute toxicity(dermal) category 1-4 substances totaled 1,020, and the number of chemical substances classified as category 1 and 2 substances were 135 and 137, respectively. In the chemical substances prescribed by the Ministry of Employment and Labor, 173 substances were classified into acute toxicity(dermal) categories 1-4, 58 of which correspond to category 1 or 2. Conclusions: Within the present range of industrial accidents, the proportion of skin diseases due to contact with chemicals is not high. However, there is always a risk of occupational skin diseases due to increasing chemicals and due to the use of new chemicals. It is hoped that this information will be used by workplace safety and health officials and health and safety experts to prevent acute toxity(dermal) due to chemical skin contact.

Background: Radiation exposure can occur as a result of occupational activities utilizing sources of radiation. The average level of occupational exposure is generally similar to the global average, but some workers receive more than this. In this study, the occupational exposure data for workers in Korea to check the recent trend of radiation exposure. Materials and Methods: The data collection and analysis are carried out by two separate periods based on the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) survey. One is the year 2003 to 2014 for a recent survey, and the other is 2015 to 2019. All available data were collected by annual reports from radiation dose registry organizations. Results and Discussion: The annual dose over the record level to the total workers did not change much compared with the total increasing number of workers in this period. The dose to the nuclear fuel cycle field has a tendency to decrease. It resulted from the efforts of radiation dose reduction with high technology introduced to this area. Also, it is important result that the radiation dose to the workers in radiography is remarkably reduced. Conclusion: The number of radiation workers and average doses were analyzed for occupational categories in Korea. It still needs cooperative efforts between the dose registry organizations for the efficient dose management of Korean radiation workers.

Background: Osteoarthritis of the knee is considered to be related to knee straining activities at work. The objective of this review is to assess the exposure dose-response relation between kneeling or squatting, lifting, and climbing stairs at work, and knee osteoarthritis. Methods: We included cohort and case-control studies. For each study that reported enough data, we calculated the odds ratio (OR) per 5,000 hours of cumulative kneeling and per 100,000 kg of cumulative lifting. We pooled these incremental ORs in a random effects meta-analysis. Results: We included 15 studies (2 cohort and 13 case-control studies) of which nine assessed risks in more than two exposure categories. We considered all but one study at high risk of bias. The incremental OR per 5,000 hours of kneeling was 1.26 (95% confidence interval 1.17-1.35, 5 studies, moderate quality evidence) for a log-linear exposure dose-response model. For lifting, there was no exposure dose-response per 100,000 kg of lifetime lifting (OR 1.00, 95% confidence interval 1.00-1.01). For climbing, an exposure dose-response could not be calculated. Conclusion: There is moderate quality evidence that longer cumulative exposure to kneeling or squatting at work leads to a higher risk of osteoarthritis of the knee. For other exposure, there was no exposure dose-response or there were insufficient data to establish this. More reliable exposure measurements would increase the quality of the evidence.

Purpose : This study aimed to evaluate the relationship between self-esteem and quality of life according to the job satisfaction occupational therapists, and to contribute to wards providing positive directions to improve the quality of work performed by the occupational therapists and their quality of life. Methods : A total of 118 occupational therapists working on site were surveyed during the study period, from April 8, 2019, to May 10, 2019. The collected data were expressed as frequency and percentage and were subjected to Pearson's correlation analysis and multiple regression analysis using SPSS (Windows ver. 20.0). Results : First, the occupational therapists' job satisfaction job satisfaction averaged 3.20 points, with the highest chance of promotion among the lower factors, followed by the conservative level, the work itself, and interpersonal relationships. Second, the analysis of job satisfaction according to the general characteristics of the subjects revealed statistically significant differences with respect to age, marital status, highest education level, service period, average pay, and average working hours of the occupational therapists. Third, the sub-category of job satisfaction and self-respect showed the most positive correlation with the person-in-charge, and the sub-category of job satisfaction and the quality of life showed the most positive correlation with interpersonal relationships. This shows that higher job satisfaction increases the self-esteem and quality of life. Fourth, the significant task satisfaction sub-factor predictor for the self-esteem of the occupational therapists was the job itself, and the significant job satisfaction sub-factor predictor for quality of life was interpersonal relationships. Conclusion : The results of this study showed that among the sub-categories of job satisfaction of the occupational therapists, work itself and interpersonal relationships had the greatest effect on the self-esteem and quality of life of the occupational therapists.

This study was attempted to understand the phenomenon in depth by exploring the special experiences of occupational health nurses who guided occupational health nursing practice education. Participants were eight occupational health nurses who had experience teaching occupational health nursing practice for more than a semester. Data collected as focus groups were analyzed by phenomenological methods. As a result of the analysis, the experience of student practice education of occupational health nurses was derived into four categories: 'Nursing student practice education started from their own experiences', 'Proceeding nursing student practice despite difficulties', 'Feel rewarding' and 'Presenting alternatives'. An understanding the experience of nursing student practice education by occupational health nurses can be used as a reference to improve or develop occupational health nursing practice curriculum, such as establishing practice regulations suitable for the characteristics of occupational health nursing practice subjects.

Objectives: This study was designed to investigate the current status of the association of job-related information such as employment status, workplace environment, and hazard material exposures with health examination outcomes. Methods: The study used data from KNHANES 2007-2009 representing the three years of 2007-2009, which was conducted annually using a rolling sampling design that involved a complex, stratified, multistage, probability-cluster survey of a representative sample of the non-institutionalized civilian population in Korea. The final analytical sample consisted of 17,240 participants. Information on age, education, smoking history and alcohol intake was collected during the health interview. Job related information consisted of employment status, workplace environment, and hazardous material exposure. The selected indices of health examination were blood pressure, fasting glucose, blood cholesterol, HDL, SGOT, SGPT, and BUN. Results: In multiple logistic regression analysis using hypertension and pre-hypertension as dependent variables and job related categories as independent variables after covariate adjustments, the odds of hypertension and pre-hypertension were significantly lower in those with responsibility and power in their job activities. Interestingly, low odds for hypertension were observed among those who reported that their jobs were fast-paced. Conclusions: This study confirmed that some job-related categories in employment status, workplace environment, and hazardous material exposure had an association with health outcome status. It is worthwhile to comment that high responsibility and power in job activities were revealed as one of the important favorable factors to improve health condition of workers.

Objectives: The purpose of this study is to provide current the recent information on indium-related adverse health effects and the Korean indium-related industries. Methods: Peer review papers were searched in environmental, occupational and medical journals with the keyword of 'Indium' and 'ITO' and reviewed. To determine the indium related industries and indium consumption amounts, references and database were investigated and analyzed. In addition, field walk-through surveys and interviews were conducted in order to collect field data and to ascertain the field situation for the processes and industries. Results: A total of 10 cases of indium lung diseases have been reported in series since the first case reported in 2001. Seven cases were found in Japan, two cases in the United States, and one in China. No indium lung case has been reported yet in Korea, but it is believed that there are high potential risks among workers in indium-related industries. There are four categories in indiumrelated- industry; indium production and smelting, manufacturing of indium products such as ITO target, the production of thin films of flat panel display, and indium recovery industry. We found that all these types of industries are operating in Korea. Therefore, it is necessary for industrial hygienists to understand the processes and industries related to indium as well as the adverse health effects of indium. Conclusions: It was found that all four categories of indium-related industry from the indium production to recovery industry are active in Korea. However, the adverse health effects of indium are not well recognized. Therefore, it is believed that there is a high risks in indium-related industry, and it is necessary to make emergency interventions.
