The aims of this study were to analyze the Korean fire fighters' applications for the public worker's compensation between 2011 and 2013 and to suggest a feasible solution for prevention of work-related musculoskeletal disorders. The Korean Ministry of Public Safety and Security provided the complete list of fire fighters' application from January 2011 to December 2013. 510 applicants with chief complaint of musculoskeletal disorders were screened out of all 1596 applicants. Male applicants were 92%. Fire fighters in their early 40's applied most frequently, followed by those in early 30's. Musculoskeletal disorders of fire fighters were reported most frequently in May and June. Regionally, Seoul had most applicants and Jeonbuk showed the highest prevalence. Low back was the most frequently reported body part followed by the knee. Ligament was insured most frequently followed by vertebral disc and bone. The fire fighter's injury occurred while fire extinguish (38.3%), emergency medical service (37.7%), rescue (12.4%), and other duties. Result of this study suggests further investigation on the large variation in regional prevalence and on the injury mechanism of musculoskeletal disorders especially during the fire extinguish and emergency medical service.

This study aimed to assess the educational need for management of communicable disease prior to developing curriculum for Field Epidemiology Specialist Training Program on Infectious Disease. We sent questionnaires(72 items) to two personnels who were related to communicable disease in each public health center through e-mai and 300 were returned(62.0% of response rate). The subject for education which showed the highest educational need was management(2.31 point), followed by immunization(2.30 point), and the lowest was surveillance(2.10 point). Generally, the educational need was higher in the aspect of attitude or practice than in that of knowledge. The subject which showed the differences in educational need by job titles were immunization(p<0.01), outbreak investigation(p<0.01), and case management and sanitation(p<0.01). There was negative correlation between communicable disease management-working duration and educational need. Considering this result, the curriculum should be focused on strengthening the ability for problem-solving especially in management and immunization.

BACKGROUND: A preliminary investigation of the radon ($^{222}Rn$) concentration has been conducted, employing solid-state nuclear-track detectors (SSNTD) and a continuous radon monitor (CRM), for fourteen randomly selected agricultural greenhouses in Jeju Island, where the underground-air was used for air conditioning and $CO_2$ supplement. METHODS AND RESULTS: The SSNTD was used to measure the average radon concentration for three months and the CRM was used for an instantaneous measurement. In order to obtain the radon concentration of a greenhouse, the SSNTDs were placed at a number of evenly distributed points inside the greenhouse and the mean of the measured values was taken. In addition, in order to assess the radon concentration of the underground-air itself, measurement was also made at the borehole of the underground-air in each agricultural facility, employing both the SSNTD and CRM. It is found that the radon concentration of the greenhouses ranges higher than those not using the underground-air and the average of Korean dwellings. While the radon concentration of most agricultural facilities is still lower than the reference level (1,000 Bq/$m^3$) recommended by the International Radiation Protection Committee (ICRP), three facilities at one site show higher concentrations than the reference level. The three-month-averaged radon concentration and the instantaneous radon concentration of the underground-air itself ranges 1,228- 5,259 and 3,322-17,900 Bq/$m^3$, respectively, and regional variation is more significant. CONCLUSION: From this results, radon concentration of the underground-air is assumed that it is associated with the geological characteristics and the boring depth of the region located of their.

Correlation between occupational exposure levels to toluene and urinary hippuric acid (HA) concentrations were studied for 124 workers at 54 work places. The highest indoor toluene concentration measured at printing process was 81.116 ppm, and their geometric average concentration was as high as 12.304 ppm. The geometric average concentration of hippuric acid in urine samples from workers who are exposed to toluene was 0.714 g/g creatinine. This is almost five times higher than the average HA concentration from non-exposure workers. Printing workers showed the average HA concentration of 1.145 g/g creatinine from their urine samples. It is the highest concentration among the workers exposed to toluene. The correlation coefficient between HA concentrations in urine and indoor toluene concentration at work places was relatively high as r=0.624 (P<0.01). But the correlations of HA with sex, smoking, drinking, age and employment history was relatively low. We can express the regression equation for the urinary HA concentration which is Y = 0.037X + 0.562 as exposure toluene concentration is X. The urinary HA concentrations showed significantly increase depend on indoor toluene concentration at work place.

Glycogen storage disease type III (GSD type III, OMIM #232400) is a rare autosomal recessive disease caused by a deficiency of the glycogen-debranching enzyme (GDE) with a mutation in the AGL gene (OMIM *610860). It is known to be bifunctional enzyme, that is, having two independent catalytic activities; 1,4-${\alpha}$-D-glucan 4-${\alpha}$-D-glycosyltransferase (EC 2.4.1.25) and amylo-1,6-glucosidase (EC 3.2.1.33) that occur at separate active sites on a single polypeptide chain. Most patients with GSD type III usually have symptoms related to decreased glycogenolysis in liver and muscles, such as hepatomegaly, hypoglycemia, failure to thrive, hyperlipidemia, muscle weakness and cardiomyopathy (type IIIa), however some patients show symptoms restricted to liver (type IIIb). GSD type III is diagnosed by enzyme test through liver or muscle biopsy or mutation analysis of the AGL gene. We report the case of GSD type III proven by gene study after liver biopsy, which revealed c.476delA, c.3444_3445insA in exon 6, 27 of AGL gene in Korean patient.

It's basically meant to make a contribution to the promotion of the oral health of shipbuilding workers and to the improvement of oral health education planning, industrial oral health policy setting and the related system, as it seems that the working environments of shipbuilding workers are very harsh due to the unique characteristics of their working process. The subjects in this study were the workers who were selected by convenience sampling from shipbuilding companies and their subcontractors in South Jeolla Province that numbered 10. The workers were surveyed to determine the relationship between their oral health education experience and oral health awareness, and the findings of the study were as follows: Out of the 310 workers investigated, 89.4 percent had no experience to receive oral health education, those who had no experience to receive oral health education fell behind in terms of oral health knowledge, awareness, concern and perception of oral health importance, and there was close correlation among their oral health knowledge, awareness, concern and perception of oral health importance. Those without oral health education experience cited lack of opportunities as the reason, the workers preferred to receive education about the prevention and treatment of dental caries, and their favorite educational method was lectures given by dentists, the workers who had oral health education experience had a more intention to receive oral health education than the others who hadn't.

The purpose of this study was to assess the need for nutritional education in male workers living in Busan, Korea. This study surveyed 310 industrial workers at five companies in Busan using a questionnaire. According to the results, need for nutritional education scored 3.60/5.00 points. The usage rate of mass media as a means of acquiring nutritional information was significantly higher (P<0.001) in subjects in their 50s compared to other age groups. Regarding scores on need for nutritional education according to theme, 'balanced eating habits' showed the highest score, followed by 'food safety', 'diet therapy related to a disease', and 'food hygiene and food poisoning prevention'. In terms of frequency of nutritional education, 29.0% of subjects considered 'biannually' to be desirable, whereas 25.8% and 21.0% considered 'annually' and 'quarterly' to be desirable, respectively. The results of this study suggest that nutritional education for industrial workers should be implemented in various ways in accordance with their characteristics. Furthermore, considering workers' low awareness levels of the need for nutritional education, employees are required to take the education in order to encouraged to improve their nutritional status and commit to a desirable diet.

The purpose of this study was to develop the first social work skills inventory in Korea. Based upon the literature review of social work skills, the examination of an existing scale, and the comments from professionals in this field, 57 preliminary items were developed. Preliminary items were evaluated with a total of 370 social workers who were working in various fields of social work in Seoul and surrounding areas. A series of exploratory factor analyses were conducted to find out the optimal structure of the scale. After deleting 30 items with low factor loadings or being cross-loaded, the scale is composed of five factors. Confirmatory factor analysis confirmed the factor structure of the scale obtained by exploratory factor analysis. The first factor was named preparatory and assessing skills to be mostly used in the beginning phase of th social work process, the second factor was named change facilitating skills to be used to strengthen motivation to change, third factor was named ending and evaluating skills to be used to terminate the professional relationship and evaluate the outcome of the relationship, the fourth factor was named resource linking and utilizing skills to be used to utilize resources in order to solve clients' problems and the fifth factor was named ethical practice skills. Each component of the social work skills inventory is found to be reliable and valid. In sum, the social work skills inventory is an instrument encompassing basic skills necessary for social work process, skills for ethical social work practice, and skills necessary for utilizing environmental resources.

This study suggests a macroscopic method of evaluating forest recreation function based on physical characteristics of forests. The method was verified by a correlation between forest recreation function in popular top 45 mountains and popularity among them, with using data-mountain area, height, distance between mountain and cities, population around mountain, and size of public service. According to analysis of the forest recreation function, it is shown that top 8 mountains, including Jirisan and Seoraksan, provide over 64% of total recreation function, while they serve the function relatively lower than mountains near mega cities-Bukhansan in Seoul-do, in terms of the function per unit area ($km^2$). It is because, in a case of national and provincial mountains, the size of mountain is likely a critical factor for determining recreation function and the distance influences on it relatively lower. These findings implicate that a large size of forests bring the recreation function to visitors on nationwide level, whileas forests in suburban provide intensively it to near population to near population.
