Background: A cancer survivor is defined as anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of their life. The purpose of this study was to examine whether physical functions, health-related outcomes, nutritional status and blood markers in community-dwelling cancer survivors aged 75 years and older are different from those who do not have cancer Materials and Methods: Two hundred seventy-five participants were asked by physicians, nurses, and physical therapists, questions regarding cancer history in a face-to-face interview. Data were collected for demographic information, physical functions, such as handgrip strength, knee extension power, abdominal muscle strength, static standing balance, walking speed and the timed-up-and-go test, health-related outcomes, nutritional status, and blood markers. The measured parameters of survivor diagnosed with cancer were compared with those without a history of cancer. Results: Thirty-seven older adults were previously diagnosed with cancer. Female cancer survivors had lower knee extension power (p<0.05), abdominal muscle strength (p<0.05), walking speed (p<0.05), timed-up-and-go test score (p<0.05), and time to spend on walking per day (p<0.05) than older women without a history of cancer. In men, none of the measured parameters were significantly different between cancer survivors and older men with no history of cancer. Conclusions: The present study shows that partial physical function of women cancer survivors aged 75 years and older differs from that in women with no history of cancer.

Background: Workplace violence was recognized to be social problems that might impact the health status and the job satisfaction of employee in hospitals. This study investigated the current status of violence and job stress among hospital employees working at administration and discharging department. Methods: The study subjects were 213 administrative employees working at 20 general hospitals. Data were collected by self-administered questionnaire that included information such as demographics, job-related characteristics, experience of violence, and job stress. The violence was classified as verbal violence, physical threat, and physical violence occurred by patients and caregivers. Analysis of variance, t-tests, correlation analysis, and multiple linear regression analysis were performed to examine the associated factors with job stress. Results: The levels of verbal violence, physical threat, and physical violence were $1.64{\pm}1.08$, $0.54{\pm}0.67$, and $0.04{\pm}0.17$, respectively. The score of job stress was $2.74{\pm}0.50$ and it was associated with age, existence of spouse, drinking frequency, subjective health status, disease history, night-time treatment, and public health administration career in simple analysis. In multiple linear regression analysis, the level of verbal violence experience was significantly associated with job stress (B=0.09, p=0.001). Also physical threats (B=0.18, p<0.001) and physical violence (B=0.48, p=0.008) showed positive association with job stress. Conclusion: This study attempted to examine the association between experience of violence and job stress in administrative employees at medical institutions. Levels of violence showed positive correlation with the job stress. Environment improvement to protect employee from violence and management of employees who experienced workplace violence are needed to reduce the job stress.

In order to evaluate the physical and psychological health effects from automobile air pollution, 99 employees who worked near a main street were given a general health questionnaire, and the prevalence of their subjective complaints was measured. The collected data were classified according to gender, sleep time, degree of regular exercise, self-consciousness of symptoms, length of employment, work time, rest time, and smoking status. The results obtained were summarized as follows: The scores related to health complaints regarding physical and psychological items were higher in females than in males. THI scores were higher for the < 4 hour sleep time group. The health complaint scores for physical items were higher in the regular exercise group, whereas most scores for mental items were higher in the irregular exercise groups. The health complaints scores for physical and psychological items were higher in the unhealthy symptom group than in other groups. Those employees who had worked for > 4 years showed significantly higher rates of complaints regarding the eyes and skin. THI scores were higher for the < 6 hour working time group. The smoking group showed higher scores regarding health complaints related to physical items. The THI scores of the respiratory organs, mouth, anus, and digestive organs were significantly higher for the smoking group than for the non-smoking group. In summary, this study shows that the health complaint scores regarding physical and psychological symptoms tended to be higher among the unhealthy group, the less sleep time group, the less work time group, smokers, and females. These results can be used to improve the psychosomatic health status and working environments of employees who work near a main street.

Objectives: The purpose of the study was to test a model of physical activity of elderly living in Korea, determine significant factors contributing the physical activity, and examine significant paths in the model. Methods: A cross-sectional study was conducted using a convenience sample of 207 elderly men and women, aged 60 and older, residing in Busan Metropolitan City. Data were collected from July to August 2009 and analyzed using Predictive Analytics Software (PASW) and Analysis of a Moment Structures (AMOS). Results: The fitness of the modified model was confirmed to be appropriate (${\chi}^2$ = 55.61, ${\chi}^2$/df = 1.32, p = .078, RMSEA = .04, GFI = .96, AGFI = .91, NFI = .90, NNFI = .94, CFI = .97, PNFI = .48). The elder's age, previous exercise behavior, and self-efficacy were significant in explaining the variance in their physical activity. We found that (a) perceived health status, perceived benefits, perceived barriers, and social support directly affected self-efficacy; (b) previous exercise behavior and perceived health status directly affected perceived benefits; (c) previous exercise behavior directly affected perceived barriers; and (d) and education level, extent of pocket money, and economic level directly affected social support. Conclusions: The younger the age, the more previous exercise experience, and the higher the self-efficacy, the more S. Korean elders demonstrated improved physical activity.

The purpose of this study is to promote understanding of physical activity and metabolic syndrome in middle-aged adults and to provide basic data of interventions development for the prevention and management of metabolic syndrome. Using the 2020 data for Korea National Health and Nutrition Examination Survey, 1,786 middle-aged adults between the ages of 40 and 64 with no missing data were analyzed. As a result of the study, 56.5(±2.1)% of men and 52.9(±1.81)% of women were sufficient activity group among physical activity, and the proportion of men was higher than that of women, but it was not statistically significant(t=1.27, p=.207). The prevalence of metabolic syndrome was 38.9(±2.1%) of men and 25.4(±1.5)% of women, the prevalence of men was significantly higher than that of women(t=5.12, p<.001). Compared to the insufficient activity group, the sufficient activity group had a 0.71(95% CI: 0.57~0.88) times the risk of developing low HDL(high density lipoprotein)- cholesterol(p=.002), and this pattern was maintained even after adjusting for age, education level, body mass index, smoking status, and drinking status(p=.002). Based on the results of this study, a physical activity and metabolic syndrome risk group in middle-aged adults should be selected, and physical activity promotion program to improve high density lipoprotein-cholesterol among metabolic syndrome indicators should be developed.

Purpose : To identify general characteristics of school personnel with recent fatigue which was the most frequent symptom among subjective symptoms and to explore fatigue-related factors by evaluating physical and perceived health status, life style, and symptoms through data mining techniques. Methods : We collected a data of the 1,147(male 545, female 602) who were elementary, middle, or high school personnel, answered a questionnaire, and received physical examination in Seoul School Health Center from September to November in 2000. And we investigated the differences between fatigue group and non-fatigue group for demographic characteristics, physical health status, perceived health status, symptoms, and laboratory values by frequency, chi-square test, t-test, or simple logistic regression analysis by SAS package 8.1, and then selected significant variables as input variables of a decision tree analysis of CART model by SAS E-miner. Results : In general characteristics, the fatigue consisted of 41.1%(male 35.2%, female 46.4%) among 1,147 school personnel. In classical statistics, factors related with fatigue were female, lower means of systolic and diastolic pressure, young age, personnel in middle school, irregular eating habit, no exercise a week or less than 30minutes exercise a day, perception of unhealthy status, and subjective symptoms including short of breath at exercise. In simple logistic regression to examine the relationship between selected independent variables and fatigue as a dependent variable, the odds ratio of gender (female vs male) was 1.58 times, and young age ( 20s vs 60s) 20.67 times, and middle vs high school personnel 1.86 times. However, we mined combined several characteristics by SAS-E miner. In CART model, if health perception was healthy, and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%. Conclusions : The fatigue consisted of 41.1%(male 35.2%, female 46.4%). In classical statistics, fatigue-related factors among school personnel were young age, female gender, perceived unhealthy status, subjective physical symptoms, poor life-style, and lower blood pressure rather than only physical health status. However, in data mining, if health perception was healthy and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%.
