Objectives: A physically active lifestyle is important for cancer survivors. Therefore, this study was conducted to 1) provide population-based estimates of the prevalence of physical activity and sitting time, and 2) their correlates in Korean cancer survivors. Materials and Methods: This study analyzed a cancer survivor subsample (N=1,482) from 2008-2013 Korea National Health and Nutrition Examination Survey (KNHANES), data selected with a complex sampling design. Overall and subgroup-specific prevalences of physical activity and sitting time were estimated. Correlates of moderate- to vigorous-intensity physical activity ( MVPA) and sitting time were tested using age-group-specific hierarchical multiple regression models. Results: Overall adherence rate to physical activity guidelines was 34.9% (95% CI=31.5-38.4). Age-group-specific adherence rates were 41.1% (95% CI=36.3-45.9) in adults (30-64 years old), and 25.3% (95% CI=21.0-25.3) in older adults (65 years or older). Adults spent 213.33 minutes (95% CI=172.4-254.3) per week on MVPA and 55.3 minutes (95% CI=36.4-64.6) on sitting time per day. In adults, sitting time was significantly associated with employed status (B=28.0, p=0.046), smoking (B=-47.4, p=0.020), and number of comorbidity conditions (B=-13, p=.037). MVPA was significantly associated with marital status (B=134.9, p<0.001), employment status (B=98.12, p=.046), and years since cancer diagnosis (B=104.7, p=0.015). Older adults spent 162.2 minutes (95% CI=119.5-204.8) per week on MVPA and 63.0 minutes (95% CI=45.0-89.5) on sitting time per day. Their significant correlates were sex (B= -45.2, p=0.014), smoking (B=-70.14, p<0.001), and years since cancer diagnosis (B=37.0, p=0.024). Age (B=5.8, p=0.042) and marital status (B=83.8, p=0.033) were also significantly associated with MVPA in older adults. Conclusion: A majority of Korean cancer survivors do not sufficiently participate in physical activity. In general, older, unhealthier, non-working, and being unmarried were risk factors for physical inactivity. While this study informs public health policy makers and practitioners about physical activity intervention demand for cancer survivors, future investigations should address psychosocial mediators to better inform intervention programs.
In order to provide the better and more effective dental health service, the study for manpower of dental laboratory technician with some relevant factors such as institutions for education and training, employment status and distribution of technicians, etc. was carried out through survey for 3,885 licensed technicians during 1965 - 1985. Results were obtained through the study as follows: 1. There are 14 junior health colleges in Korea and 3,106(79.9%) licensed dental technicians out of 3,885 graduated from health colleges and rest of them obtained their licenses through practical training in dental clinics. 2. 8,030 applicants have applied to the national examination which was carried out for 22 times during 1965 - 1985. The passing rate in the examination for 22 times showed 48.3% in average. 3. The dental technicians are working mostly in 404 dental laboratories and 2,522 dental clinics and hospitals through out the country. However, most technicians are dominantly working in large citis, because 255 (63.1%) dental laboratories and 1,537 (60.9%) dental clinics and hospitals are mainly located in Seoul and Busan. 4. Regarding distribution of the dental technician, 1,126(52.1%) technicians have been employed in the dental institutions, however, 530 (24.5%) could not have a job and the rest of them (504 technicians: 23.3%) were in leave absence from military service, travelling abroad and unknown reasons. 5. Through reference review, it was found that there were 95,886 dental technician (9/ 100,000 population) in the world during 1973$\sim$1977. However, 91,553 dental technicians lived in the developed countries (14/100,000 population)) also ratio between the dentist and the dental technician in the world showde 1:0.38. In such coentries where per capita income showed $100 in average, the distribution of the dental technician showed 0.272 per 100,000 population. 6. In an estimation of demand and supply for the dental technicians by the year from 1985 through 1996 in Korea, the supply is estimated by the capacity of educational institutions as over-production even through such estimation based on the future incresing of GNP and ratio between the dentist and the dental technicianas and also ratio between the dental technician and general population. At present such ratio shows less compared with the developed contries, however, it is estimated as over-supply in 1994.

Background: A preclinical study was conducted for evaluating a valved conduit manufactured with a glutaraldehyde (GA)-fixed bovine pericardium treated using an anticalcification protocol. Methods: Bovine pericardia were decellularized, fixed with GA in an organic solvent, and detoxified. We prepared a valved conduit using these bovine pericardia and a specially designed mold. The valved conduit was placed under in vitro circulation by using a mock circulation model, and the durability under mechanical stress was evaluated for 2 months. The valved conduit was implanted into the right ventricular outflow tract of a goat, and the hemodynamic, radiologic, histopathologic, and biochemical results were obtained for 6 months after the implantation. Results: The in vitro mock circulation demonstrated that valve motion was good and that the valved conduit had good gross and microscopic findings. The evaluation of echocardiography and cardiac catheterization demonstrated the good hemodynamic status and function of the pulmonary xenograft valve 6 months after the implantation. According to specimen radiography and a histopathologic examination, the durability of the xenografts was well preserved without calcification at 6 months after the implantation. The calcium and inorganic phosphorus concentrations of the explanted xenografts were low at 6 months after the implantation. Conclusion: This study demonstrated that our synergistic employment of multiple anticalcification therapies has promising safety and efficacy in the future clinical study.

Purpose: The purpose of this study was to investigate the relationships among health behavior, wellness condition, and stage of change in health behavior by risk of cardiocerebrovascular diseases (CVD) in male office workers. Methods: A total of 205 male office workers participated in the 2017 National Health Examination at a manufacturing/ R&D business in Seongnam and completed self-reported questionnaires. Results: There were significant differences in health behavior scores by risk of CVD (F=4.78, p=.009) and statistically significant differences in no smoking (F=5.86, p=.003), exercise (F=5.49, p=.005), and health checkup (F=4.39, p=.014). There were statistically significant differences in health behavior (t=-4.14, p<.001) and wellness condition (t=-2.61, p=.010) by the stage of change in health behavior. Health behavior had a weak positive correlation with wellness condition (r=.36, p<.001). Logistic regression analysis showed that, when adjusted for age and employment period, the probability of becoming attention or risk group was 11% lower for quitting smoking (OR 0.89, 95% CI 0.81~0.97, p=.006) and 18% lower for regular exercise (OR 0.82, 95% CI 0.70~0.95, p=.009). Conclusion: The direction of health management at the workplace should be changed to promote the wellness of all workers, not the management of the disease, and a health promotion program should be continued to emphasize health behaviors such as smoking cessation and regular exercise.

Objectives: Welding is a major task in shipbuilding yards that generates welding fumes. A significant amount of welding in shipbuilding yards is done on steel. Inevitably, manganese is present in the base metals being joined and the filler wire being used and, consequently, in the fumes to which workers are exposed. The objective of this work was to characterize manganese exposure associated with work area, total and particle size-selective mass concentration, and compare the mass concentrations obtained using a three-piece cassette sampler, size-selective impactor sampler and blood manganese concentrations. Materials: All samples were collected from the main work areas at one shipbuilding yard. We used a three piece cassette sampler and the eight stage cascade impactor sampler for the airborne manganese mass concentration of total and all size fractions, respectively. In addition, we used the results of health examination of workers sampled for airborne manganese. Results: The oder of high concentration of airborne manganese in shipbuilding processes was as follows; block assembly, block erection, outfitting installation, steel cutting, and outfitting preparation. The percentages of samples that exceeded the OES of the ministry of employment and labor by the cassette sampling method was 12.5%, however 59.1% of sampled workers by the impactor sampling method exceeded the TLV of the ACGIH. Conclusions: Even though the manganese concentrations in blood of workers exposed to higher airborne manganese concentration were higher than among those exposed to lower concentrations, there was no difference in blood manganese concentrations among work duration. The data analyzed here by characterizing size-selective mass concentrations indicates that the inhaled manganese of welders in shipbuilding yards could be mostly manganese-containing respirable particle sizes.
Objectives : Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Methods : Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Results : Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Conclusions : Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.
In order to maximize customer's satisfaction, high-value service needs to be created by reducing service delivery errors and miscommunications. Employee's job rotation experience will help them to reduce errors and develop their career. The purpose of this study is to examine the effect of job rotation on employability and subjective career satisfaction. The results clarifies the hotel's job rotation system and examine the relationship among job rotation, employability and subjective career satisfaction. Taking samples from full-time workers in hotel, total 370 participants were used in the analysis. The SEM approach was used to analysis the data with AMOS 20.0. The results show that job rotation has a positive influence on employability and subjective career satisfaction. Moreover, employability has a partial mediation effect between job rotation and subjective career satisfaction. Therefore, the study contributes to generate theoretical and practical implications in hospitality industry.

The purpose of this study was to figure out married female immigrants' experience and process of investing in human capital in Korea. The participants were 11 women from multicultural families who had experience of investing in human capital in Korea, could communicate in the Korean language, and were living in Daegu. The data were collected using intensive interviews. The major findings were as follows: The participants' level of education and work experience in native country were not accepted as human capital and offered no advantages or obtaining employment in Korea, while English language skills were useful for those pursuing an English lecturer position. The motives for investing in human capital were 'adjusting to early stage of marriage and a new environments', 'for their childrens' education', 'to improve female immigrants' level of education', 'seeking a better job', and 'advocating more education'. The types of investing in human capital were 'learning Korean language and culture', 'applying to Open University or taking a middle or high school qualification examination', 'obtaining certification', and 'entering regular university'. The participants' plans for investing in the future were 'finding their own job', 'entering regular university', and 'participating in useful educational programs including Korean language skills for daily life' The results showed that the participants' motives for investing in human capital were related in the stage of their marriage. The phases and changes in their motives during a marriage proved that the participants continued to invest in human capital according to their needs and situation.
Objectives: We evaluated the physical and mental health problems of waged workers in Korea who had different classes of occupation. Methods: We used data from the Korean National Health and Nutrition Examination Survey (2007-2017) to examine 22,788 workers who were waged employees and categorized these workers into 5 occupational classes. Results: "Unskilled manual workers" were more likely to be older, less educated, have lower monthly income, and work fewer hours per week. Among men and relative to "managers and professionals" (reference group), "skilled manual workers" were more likely to have physician-diagnosed osteoarthritis, "clerks" were less likely to report suicidal ideation, and "unskilled manual workers" were more likely to report suicidal ideation. Among women and relative to "managers and professionals" (reference group), "service and sales workers" and "unskilled manual workers" were more likely to report physician-diagnosed osteoarthritis, depressive feelings, and suicidal ideation. However, hypertension, hyperlipidemia, diabetes, and cardiovascular diseases did not differ among the occupational classes for men and women. Conclusion: We identified differences between men and women and among those in different occupational classes regarding employment status, physical health, and mental health. "Unskilled manual workers" of both genders were more likely to be older, less educated, have less monthly income, work fewer hours per week, and have suicidal ideation. Female "service and sales workers" were more likely to have osteoarthritis, depressive feelings, and suicidal ideation.
