The purpose of this study was to investigate knowledge, attitudes and practices of women toward breast self-examination and to identify factors that may influence compliance with breast examination. The subjects for this study were 282 women in three hospitals located in In-Chun. Data were collected during the period from October 15 to 30, 1993 by means of a structured questionnaire. The data were analyzed using the SAS program and include descriptive statistics, 1-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. The results of study are as follows : 1. The mean knowledge score for the total sample was 13.58. Factors affecting the women's knowledge of breast cancer and BSE were : age, level of education, experience with breast cancer patients, experience in learning BSE, information about BSE, self-practice of BSE, level of intention to perform BSE, and participation in a BSE class. 2. Elements related to attitude included : (a) perceived feeling of susceptibility to breast cancer, and (b) belief about the effectiveness of BSE. The mean perceived susceptibility score was 1.62 and the mean effectiveness score was 4.22. Factors affecting the women's perceived susceptibility to breast cancer were exercise for health, level of intention to perform BSE , intention to recommend to others and self-practice of BSE. The relation between the womens' belief about effectiveness of BSE and level of intention to perform BSE and intention to recommend to others were statistically significant. 3. The mean self-practice score for the total sample was 4.01. Factors affecting the women's practice were experience with breast cancer patients, information about BSE, experience in learning BSE, enlisting the help of significant peers, and level of intention to perform BSE. Results indicated 35.8% of the total sample practiced BSE. The most frequent reason women gave for not performing BSE was “Didn’t knew about BSE technique”, “Didn’t think do it”. 4. No relation was found between knowledge and attitudes and practices. 5. When all the variables were examined for their contribution to the variance in the practice of BSE, it was found that confidence in ability to detect a mass by BSE, knowledge about breast cancer and BSE, and experience with breast cancer patients were significant variables and explained 35.8% of the variance. From the results of this study it can be said that women need to be taught proper BSE technique so they can become more proficient in detecting breast abnormalities.

Objectives: The purpose of this study was to examine the relationship between the differences in employment status and self assessed health in Korea. Methods: We analyzed 4 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS), which was conducted on 1,207 men and 582 women who had undergone a change in employment status. The study subjects were placed into 1 of the following 4 groups based on their employment history; Non-precarious workers, Precarious to non-precarious workers, Non-precarious to precarious workers and Precarious workers. Logistic regression was then used to examine the relationship between the changes in employment status and self assessed health. Results: When males were considered, self assessed health was better among the precarious to non-precarious workers (OR 1.58, 95% CI=1.57-1.60) and the precarious workers (OR 1.29, 95% CI=1.28-1.30) than in the non-precarious workers, after adjusting for age, socioeconomic status (education level, occupational class, marital status, average equivalent household income and average number of hours worked per week), health behavior (smoking, drinking and exercise) and medical service access (regular medical examination, have chronic disease or hospitalized within 1 year). When female workers were considered, the precarious to non-precarious workers (OR 1.89, 95% CI=1.86-1.92), non-precarious to precarious workers(OR 1.24, 95% CI=1.23-1.26) and precarious workers (OR 1.27, 95% CI=1.25-1.28) all reported poorer health than the non-precarious workers after adjusting for the aforementioned factors. Conclusions: This study showed that changes in employment status were associated with differences in self assessed health among men and women. Specifically, the results of this study showed that a corresponding positive outcome based on self assessed health was greater for employees that changed from precarious to non-precarious jobs and for male employees with precarious jobs., whereas female employees with non-precarious jobs had higher self assessed health. However, additional longitudinal studies on the health effects of employment status should be conducted.

Purpose: The aim of this research was to investigate the effects of self-sit-to-stand training on balance ability and sit-to-stand ability in hemiplegic stroke patients using a multisensory feedback device. Methods: A total of 19 stroke patients participated in this study, and they were divided into two groups: 10 underwent self-sit-to-stand training using a multisensory feedback device, and 9 underwent sit-to-stand training with a physical therapist. In both groups, sit-to-stand training was performed for 30 min, 3 times a week, for 6 weeks. The subjects also underwent physical therapy twice a day for 30 min, 10 times a week, for a total of 60 sessions. Balance ability was evaluated using the AFA-50 and Berg Balance Scale. Sit-to-stand ability was evaluated using the five times sit-to-stand test. Results: Sway length, pressure, and total pressure all significantly increased in both groups, and there was no difference between the two groups. The Berg Balance Scale results showed that balance ability significantly increased in both groups, and there was no difference between the two groups. The five times sit-to-stand test results showed that sit-to-stand ability significantly increased in both groups, and there was no difference between the two groups. It was found that the self-sit-to-stand training using a multisensory feedback device had a positive effect on balance control and sit-to-stand ability. When the two groups were compared, no difference in balance ability or sit-to-stand ability was observed. Conclusion: The findings of this study indicate that self-sit-to-stand training using a multisensory feedback device is as effective as sit-to-stand training with a physical therapist. Hence, self-sit-to-stand training using a multisensory feedback device could be an effective home-based exercise protocol for hemiplegic stroke patients to improve their balance and sit-to-stand abilities.

The purpose of this study was to evaluate the relationship between lifestyle and health status among employees in a community. The participants were 199 white collar workers in J city. Data were collected from August 7 to 24, 2012 using the self-report questionnaire. Data were analyzed by descriptive statistics, t-test, ANOVA and Pearson coefficient correlation with SPSS/Win 17.0. There was a statistically significant correlation between lifestyle and health status(r= .164, p= .020). Mental component summary of health status was a statistically significant correlated with leisure activity(r= .270, p= .000) and regular exercise(r= .180, p= .011). Therefore, this study provided support for associations between lifestyle and health status. We suggest that strategies to emphasize leisure activity and regular exercise would be important for white collar workers to improve their mental health.

Objective: The aim of this study was to determine the impact of the application of whole body vibration training (WBV) on the balance ability of patients with an American Spinal Injury Association (ASIA) type C or D spinal cord injury. Design: Randomized controlled trial. Methods: Twelve patients with spinal cord injury were enrolled in this study. The participants were randomized to an experimental group (n=6) or control group (n=6). The subjects in the experimental group received WBV exercise and the control group received the sham exercise without vibration. The vibrations were adjusted vertically to the patient at a 30 Hz frequency and 3 mm amplitude. The whole body vibration lasted for 16 minutes in total including 5-minutes warm-up and cool-down at the beginning and end of the program, respectively. The static sitting balance ability was assessed by measuring the postural sway while sitting on the force plate with the eyes opened or closed. Postural sway length was measured for 30 seconds with a self-selected comfortable position. Results: In the static balance test, the anterio-posterior, medio-lateral, and total postural sway length with the eyes open and closed was improved significantly before and after the intervention in the experimental group (p<0.05). The experimental group showed significantly more improvement than the control group (p<0.05). Conclusions: Our results demonstrated that WBV training has a positive effect on improving static sitting balance and enhanced control of postural sway in patients with an ASIA-C or D type spinal cord injury.

Purpose: The purpose of this study is to determine the effect of motor imagery training on residual upper extremity strength and activities of daily living of chronic cervical spinal cord injury patients. Methods: Twelve ASIA A B patients, who had more than a 12-month duration of illness and C5 or 6 motor nerve injury level, were randomly divided into experimental group (n=6) and control group (n=6). Patients in the experimental group performed motor imagery training for five minutes prior to general muscle strengthening training, while those in the control group performed general muscle strengthening training only. The training was performed five times per week, 30 minutes per day, for a period of four weeks. General muscle strengthening training consisted of a progressive resistive exercise for residual upper extremity. Motor imagery training consisted of imagining this task performance. Before and after the training, EMG activity using BTS Pocket Electromyography and Spinal Cord Independent Measure III(SCIM III) were compared and analyzed. Results: The residual upper extremity muscle strengths showed improvement in both groups after training. Comparison of muscle strength improvement between the two groups showed a statistically significant improvement in the experimental group compared to the control group (p<0.05). SCIM III measurements showed significant improvement in the scores for Self-care and Transfer items in the experimental group. Conclusion: Motor imagery training was more effective than general muscle strengthening training in improving the residual upper extremity muscle strength and activities of daily living of patients with chronic cervical spinal cord injury.

This study was conducted to compare the dietary characteristics of middle-aged people with different obesity index or food habits. Questionnaires were collected from 480 subjects in Daejon. The data were analyzed by $X^2$-test and ANOVA. The subjects were distributed into the normal weight group(66.3%), overweight group(18.3%) and underweight(15.4%) based on BMI. Twenty-five percent of males and 23.0% of females in the 50＇s belonged to the overweight group. The least consumed food was milk or milk products among the five basic food groups. The frequency of exercise was low in their daily life. The had better food habits than the males. The overweight group had worse food habits than the normal weight or underweight group. The underweight group ate light meal and ate slowly. The better the subjects had, the more regularly they took breakfast(p＜0.001). The good food habits group were more interested in their dietary life and were more careful in selecting foods for their health than the bad food habits group(p＜0.001). Based on the results of this study, the practical education programs should be focused on more intake of milk or products and on daily exercise for the self-health maintenance of middle-aged people. Also, proper education programs should be developed for males and females in their 50＇s to practice weight control and regularity of meals in their life, and to utilize nutrition knowledge in dietary life. Further research on the comparision of dietary characteristics are needed with consideration of the subjects ratio according to BMI.

The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.

Background: The purpose of this study was to investigate the estimated proportion for influenza vaccination and to identify factors associated with influenza vaccination in Korean diabetic patients. Methods: Data from the fourth, fifth, and sixth (except for 2013) Korea National Health and Nutrition Examination Survey (n=3,726) was used. A chi-square test was performed to investigate the estimated proportion for influenza vaccination, and a multiple logistic regression analysis was used to identify the factors associated with self-reported influenza vaccination. Results: In men, 28.8% of diabetes patients 30-64 years of age, and 76.1% of elderly (over 65 years of age) diabetes patients received influenza vaccination. In women, 37.7% of diabetes patients 30-64 years of age, and 78.4% of elderly diabetes patients received influenza vaccination (p<0.0001). The determinants of influenza vaccination were marriage, hypertension (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.07-2.24), residence within a mega city, unemployment (OR, 3.94; 95% CI, 1.24-12.54), and exercise via (weekly) walking for diabetic men; and hypertension (OR, 1.71; 95% CI, 1.16-2.52), chronic disease (OR, 1.81; 95% CI, 1.08-3.02), and exercise via walking (OR, 2.65; 95% CI, 1.49-4.73) for diabetic women. Conclusion: Influenza vaccination remains relatively low in young diabetic patients. It is necessary to recommend vaccination to young diabetic patients, and to devise other strategies to improve vaccination.

The purpose of this study was to identify factors related to daily activities of post myocardial infarction patients. Data were collected from Aug. 1 to Aug. 31, 1988 through an interview schedule lasting for about 30~60 minutes by the investigators. Tools for this study were a daily activities scale and a subjective physical symptom scale developed by the researchers, and Zung's self rating depression scale. The subjects were 45 men 18 women post myocardial infarction patients who were receiving follow up care at SNU Hospital. The data were analyzed by percentage, mean t-test ANOVA, the Pearson moment Correlation Coefficient test, and Cronbach's $\alpha$ reliability test. The results were as follows. \circled1 Reliability of the daily activities scale was 0.91 by Cronbach's $\alpha$. In the daily activities scale, items about transfer, exercise, and job related activities were most highly rated as meaningful to the post myocardial infarction patients. \circled2 The average daily activities score of these patients was 3.30 (maximum point ; 4) all scores were high except for exercise and job related activities. \circled3 There was a significant difference in daily activities according to sex ; men had a higher daily activities score than women (T＝2.32, p＜0.05). \circled4 There was a significant difference in daily activities according to job status. Subjects having a job had a higher daily activities score. \circled5 The lower the depression score, the higher the daily activities score(${\gamma}$＝-0.5748, P＜0.05). \circled6 The lower the subjective physical symptoms score, the higher the daily activities score(${\gamma}$＝ -0.6015, p＜0.05).
