Coronary artery disease(CAD) is associated with a high risk of recurrence and an increased mortality rate upon recurrence. Consequently, there is a need for continuous health behavior recommendations from medical staff. Therefore, a study was conducted on 219 patients hospitalized for coronary angiography. The study aimed to investigate the influence of medical staff recommendations on exercise adherence among CAD patients. In conclusion, regular exercise(RE) recommendation(OR 3.52, p=.036) and dietary advice from medical staff(OR 6.48, p=.022), having high exercise self-efficacy(OR 1.36, p=.001) positively affected RE adherence. Therefore, medical staff should strengthen personalized recommendations for RE and healthy diets, as well as develop exercise self-efficacy enhancement programs to encourage patient participation. Future research is recommended to explore the impact of the degree and method of medical staff recommendations on self-management practices among CAD patients.

The purpose of this study was to investigate the effects of combined exercise on blood inflammatory factors, DHEA-s and arterial stiffness in elderly women. The subjects were 42 elderly females volunteers, aged 70 to 85 years, composed of the combined exercise group (n=21) and control group (n=21). The 60 minute combined exercise program(aquarobics 1 time/week, strength exercise 2 times/week) was performed 3 times per week for 12 weeks, and the intensity was progressively increased every 4 weeks(1-4 weeks: RPE 12 to 13, 5-8 weeks: RPE 13 to 14, 9-12weeks: RPE 14 to 15). The test data were analyzed by two-way repeated measures ANOVA, paired t-test, independent t-test and the alpha level of .05 was set for all tests of significance. As a result, the combined exercise for 12 weeks reduced the inflammatory response of elderly women, and DHEA-s was found to have a positive effect on aging hormone. The arterial stiffness decreased the central arterial blood pressure (systolic and diastolic), prevented the increase of the pulse pressure and the wave increase index, and decreased the pulse wave velocity. These results suggest that regular and continuous combined exercise may be recommended for the healthy aging and longevity of elderly women by inducing anti-inflammation effect and improving the aging hormonal function and the vascular health.

An efficient approach to limit analysis is presented whereby a continuous perfectly plastic structure is replaced by a discrete mathematical model. It is formulated as a mathematical programming problem using the static theorem of plasticity. The discretization is accomplished by writing the governing equilibrium equations in finite difference form, and is combined with piecewise linearization of the nonlinear yield curve, thus converting the formulation into a linear programming exercise. Examples of reported cases involving plates and shells are solved to illustrate the ease of application of the present method, its flexibility and accuracy - features which it make attractive to practising engineers.

This study was conducted to describe disease characteristics, psycho-social factors and treatment behavior of patients with lupus and to analyze relationships anions these variables. The subjects were consisted of 120 lupus patients at G university hospital in Seoul. Data were collected by means of structured interview with questionnaires, and analyzed by using frequencies, $x^2$test, t-test, ANOVA, and correlation. The results were as follows; 1. The average age of the subjects was 31.34 years and average duration of suffering lupus was about 7.3years. Severity of symptoms was moderate and the disturbance of living activities was at the very low level. 2. Self-efficacy score of lupus patients was high, and life satisfaction was at moderate level. 3. Dosage for most of the subjects was about twice a day. 16.7% of them took non-prescribed medicine and only 27.5% perform exercise. 4. Positive correlation was shown among symptom, discomfort of living activities, self-efficacy and life satisfaction, while there was negative correlation among symptom and self-efficacy, symptom and life satisfaction, discomfort of living activities and self-efficacy, and discomfort of living activities and life satisfaction. In addition, exercise showed significant relationship with discomfort of living activities, and non-prescribed medicine showed significant relationship with discomfort of living activities and self-efficacy. These results show that lupus is a chronic disease of long suffering duration among young people. Severity of the symptom was at modest level, while discomfort of living activities were relatively insignificant. However self-efficacy was relatively high. Furthermore self-efficacy has influences on symptom and discomfort of life activities, just as exercise affects discomfort of life activities. Therefore it is required to examine further measures for continuous exercise.

The purpose of this study was to investigate the effects of 12-week walking exercise on body composition, physical fitness, cardiovascular function, blood lipids, GH, IGF-1and leptin in obese and normal middle school girls. Participants included 12 pairs of middle school girls who were matched for sex, age and stratified by BMI (Obese Group: BMI$\geq$25.0; Normal Group: BMI<23.0). The variables of all factors were measured in all the subjects before and after the 12-week walking exercise program. The test data were analyzed by paired t-test, and t-test using the SPSS 14.0 statistics package and the alpha level of p<0.05 was set for all tests of significance. Body composition showed a significant difference in both groups, but the variables of physical fitness, cardiovascular function, blood lipids, growth hormone, and leptin did not show a significant difference in the two groups. We conclude that regular and continuous walking exercise improved body composition, physical fitness, cardiovascular function, blood lipids, and insulin factors in both groups. Consequently, these findings suggest that walking exercise will be effective for preventing obesity and improving health-related factors in the middle school girls.

In old age, measures to cope with the natural phenomenon of aging and various diseases of the elderly due to the deterioration of physical function are also a challenge for this society. While interest in systematic health is increasing, it is true that awareness and interest in oral-related diseases is relatively lacking. This study aims to present basic data necessary to improve the quality of life for senior citizens aged 65 or older by improving the oral dryness caused by systemic health. By research method, improve oral dryness caused by whole-body health with the elderly over 65 and promote their oral health, inducing the increase of the salivary flow rate through oral health care education, oral exercise, and salivary gland massage. First, on the DMSQ according to the general characteristics of the elderly, the recognition of the whole body and oral health status, independent sample t-test and One-way ANOVA were conducted. Second, on changes in the salivary flow rate and saliva pH according to the general characteristics of the elderly, recognition of oral and whole-body health status, and whole-body health, paired samples t-test was conducted. Studies have shown that salivary gland flow increased significantly after oral exercise and salivary gland massage, the salivary flow rate significantly increased. In all variables of the recognition of the oral health status, the salivary flow rate increased after oral exercise and salivary gland massage, and in the whole-body health, regardless of hypertension, diabetes, cardiovascular disorders, and osteoporosis, the salivary flow rate increased after oral exercise and salivary gland massage, and the salivary flow rate increased after oral exercise and salivary gland massage if the subjects responded that they did not have thyroid abnormality, anemia, abnormalities of breathing, hypotension, gastrointestinal disturbance, or kidney diseases. As a comprehensive analysis of this study, many felt oral dryness when they had a problem with the whole-body health, and many felt oral dryness when they had a problem with oral health cognition. After applying oral exercise and salivary gland massage as intervention methods in the oral health care for the elderly, the salivary flow rate significantly increased, and it is judged that the methods were very effective for controlling oral dryness. Furthermore, it is judged that the factors affecting oral health, whole-body health, and oral dryness would be identified, which would be helpful for the promotion of whole-body health and oral health. It is judged that continuous research would be needed so that measures for the application of the oral care program and system for the elderly would be prepared in the future.
