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.

Although the rare earth elements (REEs) recycling industry is expected to increase worldwide in hightech industry, regulations for worker safety have yet to be established. This study was conducted to understand the potential hazard/risk of REE recycling and to support the establishment of regulations or standards. We review the extensive literature on the toxicology, occupational safety, and health issues, and epidemiological surveys related to the REEs, and propose suitable management measures. REE recycling has four key steps such as collection, dismantling, separation, and processing. In these processes, hazardous substances, such as REEs-containing dust, metals, and chemicals, were used or occurred, including the risk of ignition and explosion, and the workers can be easily exposed to them. In addition, skin irritation and toxicities for respiratory, nervous, and cardiovascular systems with the liver toxicity were reported; however, more supplementary data are needed, owing to incompleteness. Therefore, monitoring systems concerning health, environmental impacts, and safety need to be established, based on additional research studies. It is also necessary to develop innovative and environment-friendly recycling technologies, analytical methods, and biomarkers with government support. Through these efforts, the occupational safety and health status will be improved, along with the establishment of advanced REE recycling industry.

In some ceramic industries, worker exposure to dust, crystalline free silica and lead were determined and evaluated. The conclusions are as follows. 1. Crystalline silica in bulk samples was 10.5 % in sanitary ware industry, 9.4 % in tile industry, and 2.1 % in ceramic insulator industry respectively. The free silica content of air filter sample was 8.03 % in table ware industry, 5.59 % in sanitary ware industry, and 1.32 % in ceramic insulator industry. Because silica content in ceramic dust is relatively high, it is should be considered silica as important factor in evaluating for ceramic industry. 2. The silica contents in dust from tile, sanitary ware and table ware industries are above 5%, it should be classified as "Type" 2 dust. 3. The airborne concentration of respirable crystalline silica was $27.9{\mu}g/m^3$ in a sanitary ware factory and $5.8{\mu}g/m^3$ in a ceramic insualtor factory. Three of ten samples sampled the above factories were exceeded the occupational exposure levels, $100{\mu}g/m^3$. 4. Geometric mean(GM) of total dust in 11 factories was $1.00mg/m^3$ and GM of respirable dust concentration in 5 factories was $0.33mg/m^3$. Sanitary ware industry had the highest concentration of total dust, $1.62mg/m^3$ and of respirable dust, $0.88mg/m^3$. 5. Average lead concentration in air was $0.05mg/m^3$ in glazing process of 2 factories manufacturing table ware. Five of ten sample(50%) were exceeded $0.05mg/m^3$. Therefore lead exposure in pottery industry should be considered as important problem.

Objectives: The present study examined whether smoking rate has declined in 1992-2006 and who the high risk groups were on industry classification and employment type. Methods: Data from 91,263 persons aged 25-64 years were analyzed from three rounds of the Social Statistical Surveys of Korea between 1992 and 2006. Industry indicators were divided by the 9th Korean Standard Industrial Classification. Age-adjusted prevalence of smoking was calculated. Prevalence ratios(PR) and differences(PD) were estimated using log-binomial regression analysis. Results: Age-adjusted prevalence of smoking decreased between 1992 and 2006, specially the smoking prevalence of regular employees decreased most. PD in age-adjusted prevalence of smoking were the biggest between regular and daily employees. PR of the temporary employees', daily employees', self-employed persons' in order was wider than that of regular employees. PR increased significantly increased between 1999 and 2006 for those in manufacturing, construction, wholesale & retail trade, service industries. Increases in PR(regular/irregular) for women in service industry were statistically significant. Conclusions: Despite reducing overall cigarette smoking rates in males, the smoking rate was not reduced equally by industry classification and employment type in both genders. More adjustable antismoking policies and consideration of employment type are requested to reduce inequalities in smoking.

In the process of devising an efficient meal service system for the elderly, 478 elderly were interviewed at 6 different social centers with the elderly meal service program in Seoul area to monitor degree of satisfaction and/or needs of the beneficiaries regarding the program. The survey was conducted during the month of December 2002 by well-trained interviewers using self-developed questionnaire. Results were analyzed statistically using SAS package program. Most of the beneficiaries were low economic class and 76% of them had doctor diagnosed disease(s). Among the beneficiaries of congregate meal service, mean score of 12 aspects of satisfaction was 3.72 out of 5. For most of the questions, female elderly and healthy elderly responded with higher score than male elderly and unhealthy elderly, respectively (p<0.05, p<0.01). On the other hand, beneficiaries of the home-delivered meal service were little bit less satisfied with the service (3.54 out of 5). Compared to the beneficiaries of congregate meal service, larger portion of beneficiaries of home-delivered meal service wanted more meats (28.5 % vs. 17.1 %) and vegetables (23.2 % vs. 12.3 %) as side dishes. On the other hand, the most preferred type of cooking and/or seasoning was stewing for both cases. Based on these findings, it is suggested that more fresh foods should be used than processed foods in the preparation of meals for the elderly and, more fish-, meat- and vegetable- dishes should be served to come up to the needs of the elderly. Onto this, mainly Korean style meals with some intermittent Western, Japanese or Chinese style meals served at the right temperature would suffice most of the elderly needs.

Objectives: We investigated whether the rate of depressive symptom is higher among family members of asthmatic patient compared to people who had no asthmatic family member. Methods: This study used data from the fourth and fifth Korea National Health and Nutrition Examination Survey (2007-2012). In this cross-sectional study, 15,987 men (mean age 46.4) and 20,906 women (mean age 47.4) were included. To compare the rate of depressive symptoms in individuals who had a family member with asthma and those who did not have, we analyzed data using survey logistic regression. Results: Diagnosed depression was reported by 3.0% of the study population, by 4.2% of asthmatic patient's family member, and by 3.0% of individuals who did not have a family member with asthma. Family members of asthmatic patient increased odds of diagnosed depression compared with those who did not had an asthmatic family member (odds ratio = 1.56, p = 0.008). Conclusions: To prevent depression among family members of asthmatic patient, health education for entire family of asthmatic patient need to be considered. Also, government and policy makers should give more attention to caregivers who had a family member with asthma.

This study was conducted to investigate distribution of lead particles by operation of industry, to evaluate the effect of particle size on the absorption to workers, and to recommend the Occupational Health Standard for lead. Total lead concentrations in the secondary smelting industry were higher than those in the battery and litharge manufacturing industry. Total lead concentrations in other industries except radiator manufacturing industry exceeded the standard of $50{\mu}g/m^3$. Only radiator manufacturing industry indicated lead concentrations significantly lower than those in other industries(p<0.05). Average blood lead level of workers was $85.1{\mu}g/dl$ in secondary smelting manufacturing, $51.3{\mu}g/dl$ in the battery manufacturing, and below $40{\mu}g/dl$ in the litharge and radiator manufacturing industry. Blood lead levels of workers by industry were significantly different(p<0.05). From relationship between airborne lead concentrations by size and lead in blood, confidence limits of airborne lead concentration equivalent to $40{\mu}g/dl$ of permissible limit in blood, was $147.9-489.8{\mu}g/m^3$ as total lead and $28.8-79.4{\mu}g/m^3$ as ACGIH-RPM. It is recommended that two separate occupational health standards for lead should be established by particle size. Airborne concentration of $150{\mu}g/m^3$ as fatal lead dust and $30{\mu}g/m^3$ as respirable lead dust was recommended.

The purpose of this study is to identify relationships between safety and health indices in a shipbuilding industry. From the results of periodical health examination, job stress test, and health questionnaire for musculoskeletal disorders, the author stratified the 704 shipbuilding workers into categories of smoking, drinking frequency, the amount of exercise per week, obesity, blood pressure, diabetic symptoms, liver function, audibility, job stress, fatigued condition, musculoskeletal symptom, and accident. The results show that occupational injuries are highly related to smoking, drinking frequency, auditory capacity, fatigued condition, and musculoskeletal symptoms. These results can be used to develop more effective accidental occupational injury prevention programs for shipbuilding industries.
