Objectives: The purpose of this study was to investigate whether chemical exposure among workers has relevance to dyspnea using data from the $3^{rd}$ Korea Working Conditions Survey. Methods: The research subjects were 29,711 wage workers. Chemical exposures consist of four factors, (1) breathing in vapors, fumes, dust and dirt, (2) breathing in organic solvent vapors, (3) handling or touching chemicals, and (4) secondhand smoke. Multiple logistic regression analysis was performed to examine the association between chemical exposure and dyspnea in the last 12months using proc surveylogistic in SAS 9.3 statistical software excluding people who had received a diagnosis of hypertension or obesity that can affect the respiratory distress symptoms(n=27,842). Results: Chemical exposure among workers was associated with dyspnea after adjustment for demographics and job characteristics. Prevalence of dyspnea was 4.9 per 1,000 among men and 5.8 per 1,000. Compared to a total score of 0 points of chemical exposure among workers, a total score of 1, 2-3, and 4 points tended to have increased risk of dyspnea in a dose-response manner for both men (OR=1.43, 1.93, and 4.26; P-for trend=0.002) and women(OR=1.10, 2.81, and 7.70; P-for trend=0.002). Stratified analysis by duration of current job showed that the association between chemical exposure and dyspnea tended to get stronger until 15 years and then disappeared afterwards, which reflects healthy worker survivor effect. Conclusions: We observed significant association between chemical exposure and dyspnea using the data of the $3^{rd}$ Korea Working Conditions Survey. Our results warrants providing knowledge related to chemical exposure, performing prevention activities, and creating various health policies to protect workers.

This study was to evaluate the associations between urinary S-Phenyl-mercapturic acid(S-PMA) as a new indicator of biological monitoring for low level of exposure to benzene and independent variables such as the air concentration of benzene in the breathing zone of workers, the years of work, and smoking. In this study the subjects were the total of 145 drawn from 53 workers who were occupationally exposed to benzene and 92 workers who were not. The results were as follows: 1. In the workplace geometric mean concentration of benzene in the breathing zone of workers was 0.31 ppm(0.02 - 3.26 ppm) for the spraying workers and 0.25 ppm(0.02 - 3.95 ppm) for the printing workers. 2. The geometric mean of uninary S-PMA for non exposed group was $8.9{\mu}g/g$ creatinine($0.6-72.3{\mu}g/g$ creatinine), 80.3% (74 workers) of the total non-exposed workers indicated less than $20{\mu}g/g$ creatinine of uninary S-PMA. The difference of uninary S-PMA by sex, age, smoking was not significant. 3. The geometric mean of urinary S-PMA for workers who were exposed to benzene was $37.2{\mu}g/g$ creatinine, and was four times higher than that of workers who were not exposed. And 79.3% (42 workers) of the total exposed workers indicated more than $20{\mu}g/g$ creatinine of urinary S-PMA. 4. Regarding the level of benzene in the air, urinary S-PMA was the highest level of $147.9{\mu}g/g$ creatinine in the workers who were exposed to air concentration of 0.5 ppm of benzene and was higher as the level in the air was increased. 5. The correlation coefficient between log urinary S-PMA and log benzene concentration in the breathing zone was 0.80, and the following linear equation was found between urinary log S-PMA and log benzene concentration in the breathing zone : log S-PMA(${\mu}g/g$ creatinine) = 0.564 log benzene in air(ppm) + 0.192 (n=53, r=0.80, p=0.000) In conclusion, the concentration of S-PMA in urine proved to be good parameter for biological monitoring benzene exposure at the workplace even at low level of benzene in air.

In this study the factors of fire damage are analyzed through previous research reviews. Local environmental factors as well as those factors attributed to fire damage (number of fire events, number of injured, number of death, economic loss) were selected to compose mutual relationship model. In order to verify this relationship model, official statistics concerning fire damage were collected from 228 local governments and compared with results from previous research. As a result of this comparison four dependent variables and 22 independent variables that affect fire damage were analyzed. Independent variables are divided into human vulnerability factors, physical vulnerability factors, economic vulnerability factors, mitigating factors and local characteristics. To analyze a relationship between selected dependent variables and independent variables, we applied a semi-logarithm model and performed regression analysis. Among the 22 independent variables, the number of the weak to disaster, social welfare service workers, workers in manufacturing industry, and the number of workers in restaurants and bars per 10,000 people show the significant correlation with the number of fire incidence. The number of death from fire is significantly related to two variables which are the number of social welfare service workers per 10,000 and the ratio of commercial area. Damage cost is significantly dependent on the property taxes per 10,000 people. These factors were included in the research model as vulnerability factors (human, physical, economic) and mitigating factors and local characteristics, and the validity of research model was verified. The result could contribute to fire-fighting resource allocation in Korea or they can be utilized in establishing fire prevention policy, which will enhance the national level of fire safety.

Korea's elevator industry is one of the world's eighth-largest industrial sectors and the third largest in the world by new installations. This year, the number of elevators has exceeded 700,000, and the number of new installations is 30,000-40,000 every year. However, the news of elevator-related accidents is reported continuously through the media and the accident rate is not decreasing. In particular, among the recent accidents related to elevators, accidents related to elevator workers are increasing, causing social problems. This year, the National Assembly's Environmental Labor Relations Commission's National Auditors lost five lives a year and 12 elevator workers were killed in fall and stenosis accidents during the installation, maintenance and replacement of the elevators for about two years since 2018. It took place to adopt the representatives of four domestic elevator companies as witnesses. An elevator worker is a collective term for workers involved in the design, manufacturing, installation, replacement, maintenance, inspection, management, and supervision related to the elevator industry, and the related accidents are called elevator worker accidents. Analysis of elevator-related accidents in the past has shown that the fault of the user accounted for 70% of the total, and the fault of the worker accounted for about 2.5%, and the accident occurred to the user or the user due to carelessness of the worker during the lift-related work. Currently, elevator-related accidents are reported by the Korea Elevator Safety Agency under Article 48 of the Elevator Safety Management Act under the Ministry of Interior and Safety. If deemed necessary for the prevention and prevention of recurrence of an elevator accident, the cause and condition of the elevator accident may be investigated. However, the current draft law is limited only to elevators after installation inspection, and is separated from the Ministry of Employment and Labor's data on accidents occurring in the manufacturing and installation stages related to the elevator industry. This study analyzes the recent safety accidents of elevator workers and prepares safety measures to prevent them through the risk analysis, and also draws out the problems and improvements of the current elevator worker accident investigation to find the elevator worker accident rate that is on the increase trend.

Objectives : The purpose of this study is to examine the recognition and needs on the national health insurance coverage of scaling in industry accident injury patients. National health insurance coverage of dental scaling will start in September, 2013. Methods : Subjects were 649 industrial injury patients and they completed self-reported questionnaire. Data were analysed using SPSS version 20.0 for percentage, chi-square test, t-test, ANOVA, post-hoc Scheffe test, and Pearson's correlation coefficient. Results : Recognition on national health insurance coverage of dental scaling was not fully known to industrial injury patients (24.5%). Highly educated and high income workers seemed to recognize national health insurance coverage of dental scaling (p<.001). Recognition for national health insurance coverage of dental scaling revealed a significance (r=.576, p<.001). Most of the industrial injury workers thought that 50,000 to 100,000 Korean Won of dental scaling fee is reasonable. The coverage of dental scaling should be more than twice over 20 years old. Conclusions : It is necessary to encourage the patients to take regular dental scaling checkup and make them know the health insurance coverage of scaling. The preventive oral health care may improve oral health care and quality of life.

This study was intended to analyze the clothing shopping orientations and purchasing practices for men's dress shirts. It was conducted by means of convenience sampling survey with male office workers who usually wear dress shirts at work and who also live in Seoul, Geonggi, and Chungcheong area. The data collected were analyzed by frequency analysis, cross-tabulation analysis, factor analysis, t-test, and ANOVA using SPSS. The results are as follows: 1) Clothing shopping orientations were classified into six factors: brand oriented; planned; enjoying; expediency oriented; negative shopping; and low price oriented. There were partially significant differences in clothing shopping orientations according to the surveyees' age. 2) The surveyees prioritized low price and expediency in clothing shopping, but they also showed low interest in brands. 3) The criteria for purchasing were in the order of size, color, comfort, and design. There were also partially significant differences in the estimation criteria for dress shirts according to marital status and age. 4) Most respondents tended to purchase 3 or 4 pieces of dress shirts a year, paying 30,000 to 50,000 won for a piece, usually at department stores. 5) When they purchase a dress shirt, they always considers its size. In the case of married men, however, it is the laundry tag that they do care about.

Objectives: This study is aimed to illustrate the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate by safety and health management type in workplaces. Methods: In order to analyze the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate of different safety and health management types in workplaces, selected data from the Occupational Safety and Health Research Institute were used. Results: The occupational accident rate in workplaces where safety and health managers had been appointed was lower than in those where safety and health management was entrusted to other organizations, while the result was the opposite in regards to the fatality rate per 10,000 workers caused by accident. However, the occupational fatality rate per 10,000 workers in workplaces where safety and health managers have other roles was 426% higher than those where safety and health management was entrusted to other organizations. Moreover, the musculoskeletal disorder rate of the workplaces where safety and health managers have other roles was 15% higher than those where health management was entrusted to other organizations. Conclusions: It is necessary to review the effectiveness of systems in which safety and health managers can concurrently engage in other roles.

Purpose: This study was designed to find out the related factor of the health promotion behavior of pneumonconiosis patients. Method: Data were collected by questionnaires from 160 patients in a Workers Accident Medical Center. Data were analyzed by Pearson's correlation coefficient and multiple regression. Result: There were positive correlations among health promotion behavior, self-efficacy(r=.674, p=.000), perceived benefit(r=527, p=000) and self-esteem(r-471, p=000). But there was not correlation between the health promotion behavior and perceived health state. Multiple regression analysis showed that the most powerful predictor was self-efficacy, followed by self esteem. Conclusion: This study revealed that important factors such as self-efficacy and self-esteem should be treated for increasing of the health promotion behavior of pneumonconiosis patients.
