This study examined health foods intakes and related variables among the middle aged(150 men and 159 women) in the Jeonbuk region. Health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured health food supplements(MHFS). The number of people taking health foods were higher for those in their 50's than in their 40's. The consumption rate of TF in men was the highest among health foods, this result had significance. The reasons for taking health foods were recovery from fatigue, supplement of nutrients and making smooth body activity in general, but TF was used to increase of vigor. The consumption rate of health foods was a little different according to social-economic factors, namely, the consumption rate of CM was higher in people in rural than urban areas, those who graduated from middle school than university, blue color & self-employed as opposed to housewives and service workers, low level income than high level income, and Buddhism and no religion than Christian. The consumption rate had a correlation with the habits of smoking, alcohol drinking and exercise ; namely, the consumption rate of CM was higher than VMS and MHFS on smokers and alcohol drinkers. The more the frequency of exercise, the higher the consumption rate of TF, but the duration of the exercise was not correlated. This study suggests that middle aged people need nutritional education for the right recognition and selection of health foods and to consider the nature of each type of health foods.

Purpose: This study examined the effects of the abdominal hollowing technique applied during plank exercises at different shoulder angles between the ground and the humerus on the abdominal muscle activity Methods: The subjects were 36 male volunteers. They were randomized to perform plank exercises or plank exercises using the hollowing technique at 80˚, 90˚, 100˚, and 110˚ between the ground and the humerus. The abdominis muscles were measured using a surface electromyogram. Independent t-tests examined the changes in the activity of these muscles according to the two exercise methods at each angle. The changes in muscle activity were examined according to the selected angles by one-way analysis of variance. Results: The activity of abdominal muscles was investigated according to the angle between the ground and the humerus during the plank exercise. As a result, the muscle activity increased significantly with decreasing angle in the rectus abdominis, external oblique, and internal oblique·transverse abdominis muscles (p<0.05). In terms of the changes in abdominal muscle activity after hollowing plank exercises at the given angles between the ground and the humerus, an increase in angle resulted in a statistically significant increase in the rectus abdominis muscle activity (p<0.05). The activities of the rectus abdominis, external oblique, and internal oblique/transverse abdominis muscles after hollowing plank exercises showed statistically significant increases (p<0.05) compared to those after plank exercises. Conclusion: The hollowing technique and the increase in the angle between the ground and the humerus may be an effective exercise method for increasing the muscle activity of the abdominis muscles.

This study was conducted to investigate the relationship among prevalence of obesity, nutritional status and factors related to obesity of women who exercise regularly. The subjects of this study were 100 women who have been exercising regularly for more than 6 months. They were mostly housewives ages 24 to 63 years and had graduated middle or high school. Their average income was form 700 to 1,500 thousand won per month and most of them had 2 r 3 children. They sleep usually 6~8 hours a day. Most of physical indices of obesity were increased progressively with age. Among them , weight (61.5$\pm$1.4kg), subscapular (16.3$\pm$1.4mm) and abdomen(31.4$\pm$1.2mm) skinfold thickness were higher in 50 years than in others. BMI after exericse was decreased compared with BMI before exericise. WHR was 0.82 in 40 years and 0.85$\pm$0.01 in 50- to 60- year-old group. The percentage of body fat increased with advancing years and the highest values were shown in 50 - to 60-year old group (skyndex value : 38.6$\pm$0.6, BIA value : 28.7$\pm$0.8<0.05). The prevalence of obesity was measured by bioelectrical impedance fatness analyzer (BIA), obdy mass index (BMI) and skinfold thickness were 17.0%, 24.0% and 78.0% respectively. Most subjects were in good nutritional status, but in the subjects aged 24~49, energy (89.3%), iron (93.3%) and vit. A (97.4%) intake were slighltyl lower than the RDA. Energy intake was slightly insufficient tot he 50-63year old subjects (88.6%) compared with RDA. It seemed that they restricted calorie intake for the weight control. The energy percentage of carbohydrate, fat and protein was 65 : 20 : 15, the result of which came closed to the recommended calorei composition. There were positive correlations between obesity and other variable such as age. number of childeren and physical indics.

Purpose: This study was conducted to examine the effects of a PNF intervention using elastic bands on edema, range of motion (ROM), and pain in post-mastectomy patients with upper limb lymphedema, according to their hand grip type. Methods: The subjects were 14 female patients who were at Stage II lymphedema after undergoing mastectomy for Stage II breast cancer. They were randomly divided into an experimental group (n =7) and a control group (n = 7). Both groups participated in a treatment program four times (one time under the therapist's instructions and three times as self-exercise) a week for 4 weeks. Both groups repeated an upper limb PNF pattern exercise for 30 min using elastic bands after receiving a manual lymph drainage treatment for 1 hour. Here, subjects in the experimental group performed the PNF exercise with an open-hand grip by putting their hands into the loops of elastic bands and keeping their fingers spread out. Subjects in the control group performed the PNF exercise with a closed-hand grip by holding the loops of elastic bands with their fingers. In both groups, the subjects' edema, ROM, and pain levels were measured before the intervention and 2, 3 and 4 weeks after the intervention. Results: As a result of the experiment, both groups demonstrated edema reductions, ROM increases, and pain reductions in four areas of the upper limbs. Notably, the experimental group exhibited larger ROM increases in flexion, extension, and abduction as well as greater edema and pain reductions than the control group. In particular, the most significant effects were found in the elbow of the four upper limb areas for edema reductions and in extension for ROM increases. Conclusion: The present study indicates that exercise therapy-based approaches using elastic bands in post-mastectomy patients with upper limb lymphedema can have different effects depending on the type of hand grip (open or closed), which is the body's most distal part. Therefore, these approaches should be based on the conditions of the distal parts of the patient's body for their effective applications in clinical practice.

Introduction : In Korea, national attention to the workplace health promotion programs (HPP) for employees began in early 1990s. Governmental supports for the HPP and education programs have given to the employees. The purpose of this study is to find the performance degree of employees' health promoting lifestyle(HPL). Subjects and Methods : For this study, 615 employees who attended governmental educations were selected as research samples. The tool for measuring HPL used in this study was developed for Korean by In-Sook Park in 1995. It is composed of 4-point scaled 60 items and divided into 11 subcategories. The data were collected by self reporting questionnaires from June to December in 1997. Those data were analyzed percentile, mean, standard deviation, ANOVA, t-test with SAS program. Major findings are as follows; 1. The total mean score of the employees' HPL performance was 2.66. The average scores of 'harmonious relationships' category were the highest as 3.11, whereas the one of 'professional health maintenance' were the lowest as 2.02. The remains were 'sanitary life'(2.90), 'emotional support(2.85), 'regular diet'(2.84), 'self achievement'(2.78), 'healthy diet'(2.56), 'rest and sleep'(2.56), 'exercise and activity'(2.54), 'diet control'(2.53), 'self-control'(2.52). 2. The factors affecting HLP were category of industries and sex, age, marital status, education level, major, educational experience of health promotion, among personal characteristics. The employees of service industries, female, older age, married, nurse, educated for health promotion, graduated from junior college performed HLP more than the others. 3. The participation rates of employees for HPP were 12.4%, because of limited time and facilities and equipments. Recommendations; 1. The regulation for performing the health promotion programs in the industries is essential for activating industrial health promoting movement. 2. More governmental supports for educations and services for health promotion programs in the industries are needed. 3. For behavioral changes of the employees, the contents of educations have to consist of exercise and activity, rest and sleep, diet and smoking habits. 4. The evaluating studies for ready made health promotion programs in the industries are expected.

Through a questionnaire survey of 607 respondents over 20 years old currently residing in Seoul, general conditions, items and amount of daily diet, preference of dining-out and instant food, and concern for health were surveyed and the results are as follows. A large portion of respondents, at 36.2% of all respondents, were 20 years old, 57.7% of them graduated from high school or over, and most of them(61.9%) were over middle-class level of living standard. More than half (50.9%) of whom paid less than 10% for dining-out took breakfast as a rule, and 38.3% of whom regularly took meals and 37.3% of them took their regular daily routines. But among whom spent more than 31% for dining-out 46.2% of them took snacks between meals every day. Also, among whom spent more then 31% for dining-out, about 25.6% of them usually dined out every day. On concerns for health, among whom spent less than 10% of dining-out expense, 53.9% of them took exercise almost every day and 32.8% for 30 minutes, and 34.6% of them were generally healthy and 67.5% of them had normal blood pressure. But among whom spent more than 31% for dining-out expenses, 10.3% of them were not healthy, 15.4% had higher blood pressure and 20.5% had lower blood pressure, thus those portion were relatively higher compared with the former group. From those research results, therefore, group who spent lower dining-out expenses were older people with lower educational and living level but regularly took breakfast and exercise. Thus, their daily schedules were routine and took regular meals with healthy condition. The group with lower dining-out expense took right food pattern and kept healthy condition, and, therefore, it implied that dining-out gave significant influence to food pattern of grown-ups. Therefore, nutrition education for grown-ups might be necessary again and our foods as a diet should be re-evaluated and re-highlighted. To formulate the practical nutrition education in early childhood, practical, systematic, and continuous nutrition education might be required and effective and multidimensional education programs should be developed. In addition, various menus of breakfast with diverse materials, wide range of nutrition, and being convenient and time-saving must be studied in the near future.

PURPOSE: This study compared the effects of chest expansion resistance exercise (CERE) and breathing retraining (BRT) on stroke patients' chest expansion and maximal inspiratory pressure(MIP), thereby intending to present an effective intervention method for enhancing their respiratory functions. METHODS: The subjects were 30 stroke patients and randomly and equally assigned to a CERE group (10), a BRT group (10), and a control group (10). The intervention was applied to each group five times per week, 30 minutes per each time, for six weeks. A tapeline was used to measure upper and lower chest expansion and MIP prior to and after the intervention and the results were compared. RESULTS: After the intervention, the upper and lower chest expansion was considerable in the CERE group (p<.01), significant in the BRT group (p<.05) but was not significant in the control group (p>.05). According to the post-hoc test result, the upper and lower chest of the CERE group and the BRT group significantly expanded compared to that of the control group (p<.05) and the upper and lower chest of the CERE group statistically significantly expanded relative to that of the BRT group (p<.05). According to the MIP evaluation result, the CERE group saw considerable improvement (p<.01) and the BRT group underwent significant changes (p<.05), but there were no significant changes in the control group (p>.05). The post-hoc test result was that the CERE group and the BRT group saw significant improvement compared to the control group (p<.05) and the CERE group experienced statistically significant enhancement relative to the BRT group (p<.05). CONCLUSION: As an intervention for respiratory function improvement, CERE is considered effective for strengthening respiratory muscles and promoting chest expansion through manual resistance by a therapist.
