The study was curried out to collect information to establish a framework for nutrition education for the prevention of chronic degenerative disease. We analyzed differences in diet quality, food habits and health status of workers by work condition. Anthrometric parameters of height, weight and body fat were measured and biochemical parameters including glucose, total cholesterol, GOT, GPT and hemoglobin were determinded for 194 subjects. To assess the nutrient intake and diet quality of workers, dietary intake was measured by the day 24-hour recall method, Average daily nutrient intake, except for phos-phorous and vitamin C was lower than Korean RDA. The obesity related behavior score was significantly better in laborers than in office workers, while chronic degenerative diseases related to food habit score was significantly better in laborers than in office workers, while chronic degenerative diseases related to the food habit score was beet in offices workers than in laborers. Blood pressure, blood glucose levels were significantly higher in laborer than in office workers. Dietary variety score (DVS) food composition group score(FCGS), mean adequacy ratio(MAR) of office worker were better than those of labor workers. When diet quality was evaluated by FCGS(food composition group score) 16.0% of the subjects acquired 5 points and 14.4% of the subjects acquired 2 points.　MAR and INQ showed a significantly positive correlation with DVS and FCGS . This results indicated that the onset possibility of hypertension and diabetes mellitus among chronic degenerative disease was higher in laborers than in office workers, while the onset possibility of obesity was higher in office workers than in laborers. In conclusion the overall diet quality of office workers is betters than that of laborers, therefore, nutrition education for prevention of chronic degenerative disease of industrial workers needs to be more focused on the improvement of the health status of laborers.

Purpose: This study was to identify the stages of change in smoking cessation behavior and factors associated with the stages of smoking cessation behavior according to the trans-theoretical model. Methods: The subjects were 154 industrial workers working at H Industry in N City, Chonnam Province who were currently smoking and had smoked in the past. Data were analyzed by descriptive statistics, ANOVA, and Duncan's multiple comparison test using SAS Version 10.0. Results: The subjects were distributed among the stages of change in smoking cessation behavior: there were 28 subjects (18.2%) in the precontemplation stage, 71 (46.1%) in the contemplation stage, 21 (13.6%) in the preparation stage, 8 (5.2%) in the action stage, and 26 (16.9%) in the maintenance stage. The amount of smoking per day, self-efficacy, and advantages (pros) of smoking were significantly associated with the stage of change in smoking cessation behavior. Conclusion: This study suggested that the stage of change in smoking cessation behavior of the subject should be identified prior to the application of intervention programs, nursing intervention strategies should be considered to reduce the amount of smoking per day, and the disadvantages of smoking should be perceived.

Working in the forest would require a wide range of skills and experience for specific tasks which involve with a high level of risks to worker's safety. However, there has been a concern on the current standard wage system for forest workers because it does not effectively reflect the characteristics of typical working conditions in the forest. In addition, the current standard wages for forestry workers was estimated based on the construction industry's wage system. Therefore, the purpose of this study is to assess a current wage system through the mail survey method and to develop a new wage system for forest worker which effectively reflects skill sets and experience required for successful completion of the work in the forest. We mailed the survey questionnaire consisting of 19 questions to 659 forest workers and received 188 responses resulting in a 28.5% response rate. The results showed that the current average optimal wages of forest worker, special worker and feller were 97,680won/day, 127,559won/day and 152,403won/day, respectively though there were variations depending on the regions. In developing the new standard wage system, this study suggest the current work types(worker, special worker and feller) could be divided into 5 work types (forest-environment workers, forest operations in beginner, forest operations in intermediate, forest operations in advanced and forest equipment operator) reflecting specialty of forest operation thereby stabilizing the new wage system for forest workers.

Work-related injurieshave become the issue in the twentieth century. Musculoskeletal disorders are the most common work-related injuriesand the most frequent from of work-related i11-health (more than 50％ of total work-related injuries (BLS 1990)). The workers at copy shops have complained of pain in their back, legs, and shoulders. Most of them work for more than 8 hours a day. They have claimed that their pains were associated with repetitive and continuous work over a long term. The purpose of this research is to suggest an ergonomically comfortable redesign of the copy machine. This study was performed by conducting a survey of copy shop workers who have complained of job-related physical pain, and analyzing their working postures. The copy machine was ergonomically modified to reduce the workers' pain. The VIS10N 3000 software was used to analyze the posture. The analysis showed significant difference in the ranges of back and neck motion (p<0.05).

This study examined the effects of a multifaceted intervention program on the psychological condition, empowerment, work readiness, and functional capacity for job performance of industrially injured workers. Twelve injured workers in C hospital were included in this study. The subjects participated in a social rehabilitation program 2 hours a day, twice a week, for 8 weeks in total, as well as a work hardening program 3 to 4 hours a day, 5 times a week, for 8 weeks in total. The study was conducted from March to September, 2017. A multi-dimensional psychological examination, empowerment scale, work readiness interview and functional capacity evaluation were conducted and the test scores compared before and after the program with the Wilcoxon signed rank test. In the multi-dimensional psychological examination, there were significant differences in the levels of anxiety, depression, lack of social support, and somatization symptoms (p<.05) except anger. The participants also showed significant differences in the empowerment scale, work readiness scale, and functional capacity evaluation. This study suggests that a multifaceted intervention program can be effective in improving the psychologic condition, empowerment, work readiness, and functional capacity of industrially injured workers and, in turn, may improve their rate of returning to work.

This case report attempts to present a case of acute toxic hepatitis in fire extinguisher manufacturing workers exposed to 2,2-dichloro-1,1,1-trifluoro-ethane (HCFC-123) in August 2017 in Korea. Twenty-two-year-old male workers were exposed to HCFC-123 for 1.5 hours one day and for 2.5 hours the other day, after which one worker died, and the other recovered after treatment. The workers were diagnosed with acute toxicity of hepatitis. However, exposure levels of HCFC-123 were not known with no work environment measurement done. Therefore, this study was conducted to estimate the exposure concentration of HCFC-123 via a job simulation experiment. In the simulation, the HCFC-123 exposure concentration was measured with the same working practice and working time as with the workers aforementioned. As a result, the workers who infused HCFC-123 into storage tanks were estimated to be exposed to HCFC-123 at a concentration of $20.65{\pm}10.81ppm$, and a mean concentration of area samples within a working radius were estimated as $70.30{\pm}18.10ppm$. Valve assembly workers working on valves of a fire extinguisher filled with HCFC-123 were exposed to HCFC-123 at concentrations of $91.65{\pm}4.03ppm$ and $115.55{\pm}7.28ppm$, respectively, in the simulation, and area samples simulated within the working radius were also found to be high with concentrations of $122.75{\pm}91.15ppm$ and $126.80{\pm}60.25ppm$, respectively. Nitrogen gas packing workers, who did not handle HCFC-123 directly, were exposed to the agent at a concentration of $71.80{\pm}8.49ppm$. These results suggest that exposure to HCFC-123 at high concentrations for 1.5-2.5 hours caused acute toxic hepatitis in two workers.

Korea has been rapidly industrialized during the past 35 years. During this period, Korea has emphasized only production and workers health has been ignored. Workers are most frequently exposed to organic vapors, such as thinners. This study was performed to evaluate worker exposures to organic solvents by size and type of industry. Results are summarized below. Workers were exposed to mixtures of toluene, xylenes, trichloroethylene, n-hexane, acetone, methanol, n-butanol, n-butyl acetate, and MIBK. Considering additive effects of the compounds, exposure indices (EIs) were calculated. It was found that worker exposures to organic solvents were highest in small industries and lowest in large industries. During a day shift, the highest exposure was indicated 3 - 5 p.m. in the afternoon. Workers in small industries had potential exposures exceeding permissible exposure limits for organic solvents. Local exhuast systems were inappropriate and respiratory protective devices were not supplied to the workers in small industries. Neither program for safe use and storage of toxic materials nor program for respirators was found in any of the plants investigated. Based on the results of the study, workers of small scale industries should be considered first in industrial health.

Purpose: The purpose of this study was to identify the factors influencing smoking cessation in female workers. Methods: This study was secondary analysis based on the data from the Community Health Survey, 2014 with the subjects of 2,007 female workers. The data were analyzed using $x^2$ test and multiple logistic regression. Results: 29.2% of female workers had the intention to quit smoking. The subjects with office jobs showed higher smoking cessation intention than non-office jobs. Smoking cessation intention was influenced by the amount of smoking per day, previous attempts to quit smoking, sleeping time, the presence of chronic disease, the presence of depressive symptoms, weight control behavior and subjective body images. Conclusion: These findings show that tailored interventions should be provided depending on the types of occupations in order to increase smoking cessation in female workers. In addition, smoking cessation programs need to consider not only the smoking related factors but also physical and psychological health including chronic disease, weight, and depression.

Objectives: The purpose of this study was to compare vitamin D levels, sleep quality, and anxiety symptoms between shift workers and daytime workers and analyze the mediating effect of vitamin D and sleep quality between shift work and anxiety symptoms. Methods: The subjects of the study were 6744 people who received a medical examination while working for an electronics manufacturing company in 2016. We evaluated their shift work, vitamin D levels, sleep quality, and anxiety symptoms with blood samples and questionnaires. Chi-square test, t-test and path statistical analysis were performed. Results: The shift workers had significantly higher symptoms of anxiety than the day workers, significantly lower levels of vitamin D in the blood, and significantly poorer quality of sleep. The results of the pathway analysis confirmed that blood vitamin D and sleep quality had a mediating effect between shift work and anxiety symptoms. Conclusions: Shift workers should be constantly paying attention to mental health effects such as anxiety symptoms. Shift workers should also be alerted of the risk of vitamin D deficiency, encouraged about sun exposure and vitamin D intake, and required to undergo training and counseling on sleep hygiene.

Objectives: This study was conducted to find out the prevalence and risk factors of anemia according to shift work. Methods: Data from the Korean National Health and Nutrition Survey (2016-2020) were used. 9,787 workers were divided into shift workers and non-shift workers. The work type between 6AM-6PM was defined as day work, and other work types were defined as shift work. A chi-square test was used to indicate the distribution of risk factors expected to affect shift work in both frequency and percentage. Multiple logistic regression analysis was performed to find out the relationship between anemia prevalence and shift work. Results: As a result of analysis, multiple logistic regression analysis of anemia prevalence and shift work, the OR (95% CI) of male workers on shift work was 2.186 (1.139 to 4.194) and there was a statistically significant difference. Conclusions: In conclusion, anemia in male shift workers should be considered a possibility of health problems. In the future, research based on various data collection should be conducted for research to reveal various causes or diseases of anemia in the future.
