This study examined the relations of educational level and life-style behaviors to the obesity. A total of 507 male adults aged 30 - 50 years completed the self-reported questionnaires. Educational level was used for measuring socioeconomic status. Activity at work, leisure-time activity and TV watching were measured for life-style behaviors related to physical activity, and some demographic and family history of disease as well. Subjects were categorized as obese when BMI was equal to or over 25kg/$m^2$, in which 19.7％ resulted obesity. Using multivariate logistic regression, the association between the measured factors and obesity was assessed. The odds ratios (OR) for risk of obesity did not differ with either age or monthly income. Subjects who completed high school (OR = 0.36; 95％ CI = 0.20 - 0.66) or university (OR = 0.34; 95％ CI = 0.16 - 0.71) had lower risk of obesity than those with education below middle school. Those with moderate activity level at work (OR = 0.41; 95％ CI = 0.24 - 0.72) showed lower risk of obesity than in inactive ones. The subjects watching TV more than 3.5 hr/day presented higher risk of obesity (OR = 2.46; 95％ CI = 1.28 - 4.74), compared with those watching TV less than 1.5 hr/day. The higher risk of obesity observed in high level of leisure time activity than in low one was considered due to that physical activity at work and leisure-time might counteract each other. Educational level and activity at work or leisure-time activity or TV watching were jointed and categorized, and then OR for obesity was estimated. The extent of obesity risk at a given level of each work activity or leisure-time activity or TV watching was different depending the educational level, which was significantly high when educational level was below middle school. Educational difference had no effect on activity level at work. However, higher educational attainment increased the leisure activity and reduced TV watching (p＜0.05), indicating that low education tended to contribute to more sedentary life-style. The findings of this study is concluded that low education was related to obesity in adult males, and its relation can partly be explained through acquiring inactive life-style behaviors. Individuals with low education might be more susceptible to the risk factors of obesity.

Objectives: This study was conducted to investigate general characteristics, job characteristics, characteristics of hospitals, and hospital coordinators, and to investigate the factors affecting the job satisfaction of medical workers. Methods: The data was collected through a self-reported questionnaire among 435 workers in plastic surgery and dermatology clinics in metropolitan city G. We investigated general characteristics, job-related characteristics, characteristics of medical institutions and hospital coordinators, job performance of hospital coordinators, and job satisfaction of medical workers. T-tests, ANOVA, correlation, and multiple regression analyses were conducted to investigate the factors related with job satisfaction. Results: The job satisfaction of the medical workers and the perceived job performance of hospital coordinators were $3.55{\pm}0.40$ and $3.74{\pm}0.43$, respectively. In multiple regression analysis, drinking frequency, number of night shifts, number of work days, and hospital coordinator introduction years were associated with the job satisfaction of medical workers. The more the overall job performance of hospital coordinators increased, the higher was job satisfaction(B=0.458, p<0.001). In detail, the more job roles(B=0.218, p<0.001), core competency(B=0.145, p=0.005), and leadership(B=0.099, p=0.037) increased, the higher was the job satisfaction of medical workers. Conclusions: The job satisfaction of the medical institution workers was associated with the perceived job performance of the hospital coordinator. In order to increase the job satisfaction of medical institution workers, a hospital coordinator with specialized job performance will be able to improve job satisfaction by carrying out efficient work in the medical institution.

Purpose : Several studies suggest that smoking and vitamin D level is a risk factor of metabolic syndrome. The objective of this study is to evaluate the association between smoking status, vitamin D levels and the Korean adult male and female metabolic syndrome. Methods : We assessed 3796 participants aged 19 years and older from the Korean National Health and Nutritional Examination Survey 2013, 2014. Smoking statuses were collected from self-reported questionnaires. Subjects were divided into three categories: non-smokers, former smokers, and current smokers. Vitamin D was tested by Radioimmunoassay method and the value of serum 25-hydroxyvitamin D, which is an index of vitamin D status in the body, was used. The diagnosis of metabolic syndrome was made using criteria modified NCEP-ATP III. Logistic regression analysis was used to calculate odds ratios between smoking status, vitamin D levels, and metabolic syndrome. Results : The overall prevalence of metabolic syndrome was 23.0 % in men and 15.4 % in women. After adjusting for smoking, the odds ratio for men's metabolic syndrome in current smokers was 1.77 (95 % CI, 1.30~2.41), while for former smokers OR was 1.63 (95 % CI, 1.15~2.31) compared with nonsmokers. After adjustment vitamin D, the odds ratio for women's metabolic syndrome in vitamin D deficiency was 1.44 (95 % CI, 1.11~1.87) compared with normal. Conclusion : Smoking status was associated with an increased risk of metabolic syndrome in Korean adult males and decreased vitamin D level was associated with an increased risk of metabolic syndrome in Korean adult females.

Objectives : To inquire the prevalence and the risk factors for myofascial pain syndrome (MPS) on young boys in order to use these results as the fundamental data for the prevention of their MPS. Methods : For 7 days in May 1999, this research was taken on 489 male students ranging from 6th to 12th grade. We randomly selected a class for every group and from these classes we operated physical examinations, self-reported questionnaires and from a rehabilitation doctor, MPS test was taken. Thoracic kyphosis and lumbar lordosis were also taken by using the inclinometer. We defined MPS as a regional pain complaint, palpable taut band that is painful on compression. Results : The shoulder MPS prevalence of the subjects were 29.7 persons/100 persons. The statistics revealed that as grades went up, the percentage significantly increased in the MPS prevalence. As of case-control study, 145 students who were tested postive in all aspects were placed as cases, and 176 students who were perfectly normal as controls on risk factors. As a result of comparing the student groups who were stisfied with their chairs to the student groups were not satisfied, the taller showed a significantly higher odds ratio (p<0.01). By the multiple logistic regression test, we concluded that the MPS disease was prevailed far more in the students in the higher grades (Odds ratio: 1.16, 95% C.I.: 1.03-1.31), and also those who were dissatisfied with their chairs than in the ones who were satisfied (Odds ratio: 1.92, 95% C.I.: 1.17-3.17). Conclusions : Significant correlations showed between the MPS diagnosed group and the students who are dissatisfied with their chairs. As a result, more research and observation has to be made concerning this disease, and the desks and chairs should be adjusted to suit the student's physical standards.

Early detection of cancer biomarkers in the blood is of vital importance for reducing the mortality and morbidity in a number of cancers. From this point of view, immunosensors based on nanowire (NW) and carbon nanotube (CNT) field-effect transistors (FETs) that allow the ultra-sensitive, highly specific, and label-free electrical detection of biomarkers received much attention. Nevertheless 1D nano-FET biosensors showed high performance, several challenges remain to be resolved for the uncomplicated, reproducible, low-cost and high-throughput nanofabrication. Recently, two-dimensional (2D) graphene and reduced GO (RGO) nanosheets or films find widespread applications such as clean energy storage and conversion devices, optical detector, field-effect transistors, electromechanical resonators, and chemical & biological sensors. In particular, the graphene- and RGO-FETs devices are very promising for sensing applications because of advantages including large detection area, low noise level in solution, ease of fabrication, and the high sensitivity to ions and biomolecules comparable to 1D nano-FETs. Even though a limited number of biosensor applications including chemical vapor deposition (CVD) grown graphene film for DNA detection, single-layer graphene for protein detection and single-layer graphene or solution-processed RGO film for cell monitoring have been reported, development of facile fabrication methods and full understanding of sensing mechanism are still lacking. Furthermore, there have been no reports on demonstration of ultrasensitive electrical detection of a cancer biomarker using the graphene- or RGO-FET. Here we describe scalable and facile fabrication of reduced graphene oxide FET (RGO-FET) with the capability of label-free, ultrasensitive electrical detection of a cancer biomarker, prostate specific antigen/${\alpha}$ 1-antichymotrypsin (PSA-ACT) complex, in which the ultrathin RGO channel was formed by a uniform self-assembly of two-dimensional RGO nanosheets, and also we will discuss about the immunosensing mechanism.
