Dose distribution of Korean radiation workers classified by occupational categories was analyzed. Statistics of the occupational radiation exposure(ORE) in 2002 of the radiation workers in diagnostic and dental radiology were obtained from the Korea Food and Drug Agency(KFDA) who maintains the database for individual radiation dose records. Corresponding statistics for the rest of radiation workers were obtained by processing the individual annual doses provided by the Korea Radioisotope Association(KRIA) after deletion of individual information. The ORE distribution was classified in term of 28 occupational categories, annual individual dose levels, age groups and gender of 52733 radiation workers as of the year of 2002. The total collective dose was 66.4 man-Sv and resulting average individual ORE was 1.26 mSv. Around 80% of the workers were exposed to minimal doses less than 1.2 mSv. However, it appeared that the recorded doses exceeded 20 mSv for 43 workers in the industrial radiography and for 147 workers in the field of radiology. Particularly, recorded doses of 23 workers in radiology exceeded the annual dose limits of 50 mSv, which is extraordinary when the working environment is considered. It is uncertain whether those doses are real or caused by careless placing of dosimeters in the imaging rooms while the X-ray units are in operation. No one in the workforce of 16 operating nuclear power plant units was exposed over 20 mSv in 2002. Number of workers was the largest in their 30's of age and the mean individual dose was the highest in their 20's. Women were around 20% of the radiation workers and their average dose was around one half of that of man workers.

The purpose of this study was to understand socio-demographic factors related to older adults' participation patterns in lifelong education. For the purpose, this study used the raw data of 2017 Survey of the Living Conditions of the Elderly (SLCE) conducted by The Korea Institute for Health and Social Affairs. From the data of 10,073 older adults, their lifelong education participation, participating program types, participating organizations, and participating frequency were analyzed by their sex, age, educational level, household income, the longest job status, and health status. This study found that female, age of 70-74 and 75-79, educational levels of high school and higher, the longest job status of regular employees and unpaid family workers, and decent health status of older adults more participated in lifelong education. According to lifelong education program types, significant differences were found between education groups of middle school/lower and groups of high school/higher and between 1, 2 quintile income groups and 3, 4, 5 quintile income groups. In relation to the participating organizations, groups of 70 years and older, middle school and higher education level, under 3 quintile income, and poor health tended to participate in lifelong education at the elderly welfare center, senior citizens, and elderly classrooms. In terms of participation frequency, high school and college/higher than 0 year of school education, and regular workers than unpaid family workers were more frequently participated in lifelong education. This study showed the inequality in lifelong education participation according to older adults' demographic characteristics; finally, this study suggested necessary policies and academic discussions for future older adults' lifelong education.

This study examined and compared the droplet infection prevention activity and cough etiquette knowledge among nursing hospital workers. Data were collected from March 4 to 29, 2019, through personal interviews using a questionnaire in 177 nursing hospital workers (health care provider: n=61, non-health care provider: n=116). The data were analyzed using a x²-test, Fisher's exact test, independent t-test, and ANOVA. The general characteristics were statistically significant between the two groups in terms of sex and age. The prevention activities of droplet infection showed statistically significant differences between the two groups in usually carrying a tissue, usually carrying a handkerchief, usually carrying a mask, carrying a handkerchief at respiratory symptoms, hand washing frequency, and cough etiquette compliance. Knowledge of cough etiquette showed significant differences between the two groups. The knowledge of cough etiquette, according to the non-health provider's prevention activities of droplet infection, was statistically significant in usually carrying a mask and cough etiquette education. Therefore, it is necessary to raise the knowledge about cough etiquette and develop strategies for habitual cough etiquette for each nursing hospital worker.

This study attempted to investigate the difference in service orientation according to the individual characteristics of hair salon workers, and to identify the internal marketing factors of hair salon that influence service orientation. Questionnaires for empirical research were collected from hair salon workers in Gyeongnam, and the results of analyzing the collected questionnaires through IBM SPSS Statistics 26 are as follows. First, as a result of analyzing the difference in service orientation according to the individual characteristics of hair salon workers, the '40s or older' group and the 'working period of 10 years or longer' group showed statistically higher service orientation than other groups. Second, as a result of analyzing the causal relationship between internal marketing and service orientation, it was found that welfare, compensation system, education and training of internal marketings had the statistical effect on service orientation, and in particular, the compensation system had the strongest effect on service orientation. Therefore, service orientation for customers should be improved through internal marketing activities that take into account the individual characteristics of hair salon workers. The improvement of service orientation means the customer's intention to reuse, suggesting that ultimately the management performance of hair salon companies can be further improved.

This study was designed to estimate the prevalence of arthritis and to identify subgroups with high prevalence rates of arthritis. Study subjects were 18,406 Korean adults aged 19 and more from the 4th (2007-2009) Korea National Health and Nutrition Examination Surveys data. Annual self-reported prevalence and its rate ratios by demographic and behavioral factors were calculated using SAS 9.2 with survey procedure. The result was as follows. The crude prevalence of arthritis was 11.7% (osteoarthritis 10.2% and rheumatoid arthritis 1.7%). The prevalence was increased by age strata (2.4% in 19-44 aged, 16.4% in 45-64, 38.3% in 65 and more). After adjusting for age, we found the subgroups with high prevalence: older people, women, residents in non-apartment area, separated and divorced people, people with low education, people with several occupations (agricultural and fishery workers, elementary occupations, and unemployed), people with low household incomes, people with medical aid, and people with higher BMI. Those subgroups may be target populations in community health programs to control the disability from arthritis.

This is a study of the determinants of sexual, contraceptive, and abortion behavior among unmarried female adolescents and young adults, which has emerged as a growing and serious health problem in Korea. As part of a larger project, data were gathered in three export zones: Kuro (Seoul), Kumi (Kyngbuk) Masan Changwon (Kyongnam) ; and the study samples are regrouped into three categories: 1) factory workers, i.e. , the reference group serving as program participants, 2) entertainment workers, and 3) ob-gyn patients. This study indicates that entertainment workers are at highest risk of experiencing premarital sex, STDs, contraceptive failure, unwanted pregnancies, and induced abortion. Of them, 20 percent had STDs as a result of first sexual experience: and about seven tenths had two or more pregnancies due to the adoption of low-efficacy methods. The proportion of those who had ever been pregnant was 60 percent for the group as a whole: 36 percent for the program participants: 64 percent for the entertainment workers ; and 91 percent four the ob-gyn patients. These proportions are exactly the same for abortion in each group, which means that all pregnancies ended in induced abortion. Of the respondents who said that they were sexually active at the time of survey, abortions were very high: 1.6 for the program participants, 2.3 for the entertainment workers, and 1.9 for the ob-gyn patients. About 80 percent of the women had abortions during the first trimester, and two thirds of the first abortions took place between the ages of 20 and 23. About one fourth experienced post-abortion complication, which was highest among the program participants (39 percent). Sixty percent of those with complications visited a hospital or took medicine to treat the problem. Even after the experience of induced abortion, the use of contraception was very low, except among the entertainment workers, whose level of use reached 53 percent. The most obvious recommendation, arising from this research, is that 'good-quality' counselling and family planning services be established under the auspices of both national and local government, particularly targeted for the entertainment workers as well as the factory workers in various textile, electronic, manufacturing, and other industrial sectors. We believe that entertainment sectors should be restructured radically so that young women who work for amusement bars and other entertainment sectors obtain protection from the risk of having unwanted pregnancies, STDs, and induced abortion.

A survey on sanitary management at 98 food service institutions located in Jeollabuk-Do were conducted. Food service institutions included 13 hospitals, 38 schools, 40 enterprises, and 7 others. The sterilization in boiling water was used for disinfection of tableware, spoon and chopsticks, and dish towel. Cooking kit, refrigerator, chopping board, and knife were sterilized with disinfectant. Frequency of sanitary training program on employees was 56.1% for 1 time/month, 12.2% for 2-3 times/month, and 11.3% for 1 time/week. Preparing ratio of defrosting, warehouse and rest room, and washing and sterilization diary were 73.8, 60.5, and 54.5%, respectively. However, checking ratio of environments (9.5%), personal sanitation (10.8%), and sanitary training program diary(8.4%) were low. Major obstacle factors on the introduction of Hazard analysis critical control point (HACCP) system into food service institutions were lack of equipment and facilities (54.1%) and lack of understanding and data on HACCP system (17.3%). Therefore, in order to reduce the outbreak of food-borne diseases increasing frequency, we estimated that the introduction of sanitary management system and the conversion of dietician' perception on sanitary managements in food service institutions were needed.

This study aimed to implement the enhancement program for the social work practice competency for children of community child center workers and to evaluate the program's effects. For this purpose, the program was implemented for ten community child center workers five times for five weeks(once a week, 120 minutes per session). For the quantitative evaluation, a non-equivalent control group design among quasi-experimental designs was used, and for the qualitative evaluation, the written materials related with the program were collected and analyzed. The results of the quantitative evaluation revealed that the social work practice skills and worker-client relationship empowerment of the community child center workers who participated in the competency enhancement program were significantly improved. In the qualitative evaluation, the subjective experiences were presented, including the improvement of the worker's practice competency and the worker's awareness of the changes in the child, the recognition of the strong points and the points to be improved in the program. This study is expected to raise the expertise and effectiveness of community child center workers, and ultimately, to contribute to the healthy development and the improvement of the mental health of children by improving the social work practice competency of the workers in community child centers, which comprise the representative service delivery system for children in South Korea.
