Health effects of pesticide among vinylhouse workers in Sangjoo County, Kyungpook Province were assessed by measuring cholinesterase, glutathion reductase, and methemoglobin. Activities of cholinesterases among vinylhouse workers and general farmers were 3.89U and 3.98U in serum and 5.29U and 5.50U in red blood cells, respectively. While levels of methemoglobin between vinylhouse workers(0.16%) and general farmers(0.17%) were very similar, glutathione reductase among vinylhouse workers were 8% lower than that of general farmers. Inhibition of RBC cholinesterase among vinylhouse workers was two times greater than general farmers, suggesting a greater exposure of vinylhouse workers to the organophosphate pesticides. Methemoglobin level among vinylhouse workers with more than or equal to 10 vinylhouse units was 13% higher than that of the workers with less than 10 units. Vinylhouse workers using protective gears during pesticide spray showed higher level of reduced glutathione and lower level of methemoglobin, as compared to the non-users. This indicates that protective gears play an important role against pesticide exposure. Vinylhouse workers practicing good personal hygiene showed a higher level of reduced glutathione, as compared to those with poor personal hygiene, indicating that personal hygiene is also an important factor in reducing pesticide exposure. The present study represents a first attempt to analyze cholinesterase, methemoglobin and glutathione reductase activities among the vinylhouse workers. While neither vinylhouse workers nor general farmers showed abnormal findings among biochemical parameters used in the present study, increased level of methemoglobin and decrease of glutathione reductase activity among vinylhouse workers suggest that these workers have been subject to a higher exposure of pesticide than general farmers.

Purpose: The purpose of this study is to find out the cognizance of medical device safety information (MDSI) monitoring in the hospital and oriental hospital workers, and the different aspect of MDSI between oriental medical devices and medical devices. Methods: The survey was performed both in the oriental medicine hospital and general hospital. The survey had 16 items; 2 items basic questions, 5 items in the awareness of MDSI, 5 items in the education of MDSI, 4 items in the necessity of defining oriental medical devices and differences between general and oriental medical devices. A total of 120 hospital worker were participated; 60 oriental medicine hospital workers and 60 general hospital workers. They had worked in the oriental medicine or general hospital associated with 'Medical Device Safety Monitoring Center, Dongguk University Ilsan Hospital' in 2019 and 2020. Results: The cognizance of MDSI was high both in oriental medicine hospital and general hospital workers and there were no significant differences between oriental medicine and general hospital workers. When we divided the hospital workers into the senior workers who had worked for over 3 years and junior workers for less than 3 years, the senior workers had higher awareness of MDSI than junior workers. However, the cognizance of education of MDSI was high which was not different between senior and junior workers. Both hospital workers thought that it was necessary to define oriental medicine device legally and the oriental medical device might have low risk and less side effect than medical device. Conclusion: The cognizance of MDSI was high and there was no significant differences between oriental medicine and general hospital workers. Because the senior hospital workers had higher recognition of MDSI, we need to provide the continuous education program for junior hospital workers. Although oriental medical device are thought to be safer than medical device, we need to have a legal definition.

Objectives: This study compared the characteristics of the work environment between agricultural and general workers and analyzed the effects of agricultural working characteristics on work-related health problems. Methods: The participants of this study were 2,347 agricultural workers and 48,042 general workers who were selected by applying standardized weights to the raw data of 50,538 respondents from the 6th Korean Working Condition Survey (KWCS). Variables applicable to both worker groups and related to exposure to hazardous risk factors in the working environment, working hours and intensity of work, health problems and work-related status, and satisfaction with the work environment were selected. Chi-square tests and independent sample t-tests were performed to evaluate the differences in the variables between the two groups. Multivariate logistic regression analysis was conducted to analyze the effects of work environment characteristics on work-related health problems. Results: Compared to general workers, agricultural workers were more exposed to hazardous environments, irregular work patterns such as working on Saturday/Sunday, and short repetitive tasks. They reported more work-related and general health problems, including back pain, upper extremity muscle pain, lower extremity muscle pain, and general fatigue. Agricultural workers showed lower satisfaction with their work environment than general workers. Factors affecting one or more work-related health problems included gender, working years, hazardous factors, irregular work pattern, working hours, and labor intensity. Conclusions: Our findings showed that agricultural workers were relatively more vulnerable to safety issues compared to other occupational groups. Therefore, it is necessary to establish standardized safety and health standards and strengthen systematic safety and health management policies and services for agriculture.

Background: During and after the Fukushima nuclear disaster (FND), many parents were concerned about the effects of radiation on the health of their children. Purpose: To clarify the factors that influenced general workers living with children and the effect of child age groups in implementing preventive behaviorsagainst radiation following the FND. Materials and Methods: A descriptive study of preventive behaviors among general workers was carried out 3-5 months after the nuclear disaster. The subjects were 1,394 regular workers, who took part in radiation seminars run by the Fukushima Occupational Health Promotion Center between July and September, 2011. In total, 1,217 responses were submitted, of which 1,110 were eligible for the present study. This anonymous questionnaire survey inquired about the presence and age of children in the household and about radiation preventive behavior implemented after the FND. The contribution of each variable was assessed by logistic regression analysis. Results: General workers in Fukushima who lived with younger children performed more preventive behavior against radiation during and after the FND. In particular, both location-related and daily routines were practiced significantly more frequently (p<0.01) by workers living with a child in the age ranges of 0-6 (8 of 10 items) and 7-12 (5 of 10 items). Conclusions: This is the first study to assess the positive association between living with children by age group and increased preventive behavior against radiation implemented by general workers after the FND.

This study examined the perceptions of emotional labor among the National General Hospital and Private General Hospital in Chungcheong area. The purpose of this study is to examine the perceptions difference of public and private general hospitals. In addition, we tried to analyze the effect of emotional labor on organizational commitment by distinguishing between workers in National and Private General Hospitals. The purpose of this study is to provide the theoretical base data for mitigating emotional labor of hospital workers in the future. The results of the analysis are as follows: First, In the case of employees working at the National General Hospital, the influence of the emotional labor of the hospital workers on the organizational commitment of the hospital workers increased as the frequency of emotional expression increased. However, it was found that as attentiveness of emotional expression and emotive dissonance deepened, the degree of organizational commitment of hospital workers decreased. On the other hand, the influence of emotional labor of the hospital workers on the organizational commitment of the hospital workers in the Private General Hospital was found to be better in the organizational commitment as they pay more attention to emotional expression. However, in the case of emotive dissonance, The more deeply emotive dissonance, the less the organizational commitment of Private General Hospital workers. Second, the frequency of emotional expression in the hospital workers' perception difference of emotional labor was higher than that of the National General Hospitals. However, in the variety of emotional expression, it was confirmed that the employees of the Private General Hospitals had more varied expressions of emotions than those of the National General hospitals. In addition, it was found that the difference of recognition of the organizational commitment of the hospital workers according to the type of hospital work was higher in the organizational commitment of the employees of the National General Hospital than those of the Private General Hospitals.

The aim of this study was investigating the consumers' and apparel firm worker's awareness and reliability of the environmental friendly textile materials. The subjects of the questionnaire survey were general consumers(n=235) and workers at Korean apparel firms(n=236). The questionnaire was developed to measure the awareness and reliability on nine environmental friendly textile materials. The results showed that general consumers had a higher reliability on the function of the environmental friendly materials but had a lower awareness than the workers at the apparel firms. Women and subjects, who experienced in purchasing the environmental friendly products, had higher awareness and reliability of the environmental friendly textile materials than others. The workers at apparel firms had higher awareness of the environmental friendly textile materials than the general consumers, but the reliability on the function of the materials was relatively low. The reliability and awareness differed by the firms' major products and their jobs. The workers at the children's clothing firms and sportswear firms had higher level of awareness about the environmental friendly textile than the workers at the casual-wear firms. The workers' awareness on environmental friendly textile materials was differentiated by their jobs. The product developers and material buyers had higher awareness on the environmental friendly textiles compare to the workers of the sales or marketing division. These results imply that promoting environmental friendly textile material to the sales person is needed in order to increase the sales volume of the products.

Purpose: This research aims to investigate into company workers' awareness of scaling and related factors and provide basic materials for setting up appropriate policies to improve the hygiene of the mouth of industrial workers and developing training programs for the worker's hygiene of their mouth, as part of researches to establish schemes for improving the workers's hygiene of their mouth. Method: Questionnaire was conducted by convenience sampling for 220 office workers belonging to H Group located in Seoul Metropolitan city over about 5 weeks between December 17, 2007 and January 20, 2008. The questionnaire for this study was constructed in consideration of general characteristics of the subjects, behaviors of the dental management. and scaling. The collected questionnaires were electronically processed using SPSS 12.0. Result: The followings are the findings of this research. First, in general, scaling is experienced by male unmarried worker in their 40s. whose monthly average income is 1.00-1.99 million won and have little interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is not good. Second, scaling is experienced once every six months by the worker in their 50s or older, who are college graduates and have much interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is good. Third. scaling is not periodically conducted because of high costs of it in terms of almost every parameter of general characteristics. Fourth, they have correct knowledge of scaling since they regard it as 'removing of plaque and tartar' in terms of every parameter of general characteristics. Fifth, the workers' sex (pE0.05), hygienic condition of the mouth (pE0.05) and knowledge of scaling (pE0.001) have a significant effect on their scaling experience. Conclusion: It is considered that dental health management should be continued by training of the importance of prevention through scaling as measure for dental health promotion of workers.
