This study investigated factors that affect stress recognition, depression, suicidal thoughts and health-related quality of life for diabetics over 50 years of age. Five hundred one diabetics were surveyed who participated in the 4th Korea National Health and Nutrition Examination Survey 2009. The data were analyzed with multiple regression analysis and Structural Equation Model to determine the factors. The results are as follows. Men, older and lower income groups, those not involved in economic activities, smokers, and drinkers showed a lower quality of life (p<0.001). There was no correlation with moderate-intensity exercise. Stress recognition (t=-4.229, p<0.001), depression (t=-2.156, p<0.05), and suicidal thoughts (t=-3.274, p<0.001) had significant effects on the quality of life (p <0.001, $R^2=0.25$). The most important of these factors is stress. Being diagnosed as a diabetic changes the lives of patients, who come under stress from controlling their blood sugar level. Societal support should be developed to help patients cope with the challenges of diabetes.

Purpose: The purpose of this study was to identify the effects of the cognitive training program on cognitive function, stress and depression in geriatric hospitals. Methods: The subjects of the experimental group were 17 elderly patients who attended the cognitive training program in Geriatric Hospitals and the subjects of the control group were 15 elderly patients who attended in geriatric hospitals. The persons in training group must take cognitive training program for 4 weeks by 3 times a week. The Mini-mental State Examination Korea version (MMSE-K), Geriatric depression Scaleshort form-Korea version (GDS-K) and Korean Computerized Neurobehavioral Test (KCNT) were utilized to determine cognitive function, stress and depression. The collected data were analyzed by descriptive statistics, t-test and ANOVA using SPSS/PC 12.0 program. Results: Cognitive function (t=-7.625, p=.000) in the elderly after receiving the cognitive training program was significantly more improved than before intervention. Also, Stress and depression (t=2.73, p=.004) was significantly more reduced than before the intervention. Conclusion: This cognitive training program was partially effective in improving cognitive function, neurobehavioral performance and reduce stress and depression. Therefore, it is recommended that this program be used in clinical practice as an effective nursing intervention in geriatric hospitals.

Heart related diseases mainly caused by heavy work load and increasing stress in human daily life. Therefore, researches on mobile healthcare monitoring for daily life has been carried out. Notably, wearable healthcare monitoring system which has least restriction has been tried to provide an emergency alert of abnormal heart rate. In this study, we developed chair type unconstrained BCG measurement system which able to perform continuous heart status monitoring at the office and daily life in the unconstrained way. Furthermore, adaptive threshold is used to detect the heart rate from BCG signals. The HRV(heart rate variability) is calculated from heart rate interval. ECG signal measured using conventional method and BCG signal measured using unconstraint system are carried out simultaneously for the purpose of performance evaluation. From the comparison result, BCG signal shows a similar heart beat characteristic as ECG signal. This proves the possibility of practical implementation of unconstraint healthcare monitoring system. In addition, medical examination like valsalva maneuver is performed to observe the changes in HRV due to stress. By performing valsalva maneuver, heart is said to be placed under an artificial physical stress condition. Under this artificial physical stress condition, the time and frequency domain of HRV parameters are evaluated.

The purpose of this study is to analyze the association of smoking cessation attempts and the perceived stress level and to identify the factors affecting the perceived stress level of quit smoking. The study utilized the 2015 Korean National Health and Nutrition Examination Survey, and was applied an Ordinal Logistic Regression to examine the association of smoking cessation attempts and perceived stress level. The current smoker those who experience failure in smoking cessation, were more stressful than those who experience success in smoking cessation (OR=1.72, CI;1.41-2.08). This study identified smoking cessation failure as a major psychiatric factor associated with high perceived stress level, and suggests high stress after smoking cessation failure as one of the reasons why smokers do not reach complete smoking cessation. Also, in order to promote smoking cessation, it is needed to have political approach in reducing the psychiatric hurdle like high stress after smoking cessation failure.

Purpose: The purpose of this study was to investigate the risk factors related to prehypertension in Korean adults. Methods: The data were obtained from the Korean National Health and Nutrition Examination Survey 2005. The subjects of this study were 3,981 adults aged over 20 years of age. Demographic characteristics, alcohol drinking, smoking, physical activity, stress, BMI, serum lipid profiles and blood pressure were analyzed in this study. Results: Prevalence of prehypertension was 38.9% in this study. As the result of multiple logistic regression, the risk of prehypertension in male, elderly and low income persons was increased. And the risk of prehypertension was increased in the case of problem drinking, alcohol abuse, formal smoker, overweight, obesity and hyperlipidemia in triglyceride. Conclusion: To decrease prehypertension prevalence, it is necessary to detect and manage the influencing risk factors of prehypertension such as alcohol drinking, smoking, obesity, physical activity, stress and serum lipid profiles.

Objectives : The objective of this study is to report the improvement of two patients with Iliolumbar ligament syndrome showed a physical examination positive. Methods : Two patients were treated by acupuncture therapy with chuna therapy at pelvic. We evaluated the effectiveness by numerical rating scale (NRS) and Oswestry Disability Index(ODI). Results : Both patients improved significantly NRS score and ODI score. And both patients' symptoms were alleviated. Iliolumbar ligament stress test was changed from positive to negative. Conclusions : We conclude that acupuncture therapy with chuna therapy at pelvic is an effective treatment to reduce the iliolumbar ligament originated pain. But there is a limit on this study due to sufficient number of cases. Further studies will be needed.

In this work, an experimental examination was carried out to study interfacial stresses developed at the junction zones between carbon fiber reinforced plastic (CFRP) fabrics (~1 mm thickness) and tensile concrete portion in CFRP retrofitted RC beams. In this respect, initially six similar RC beams of $150{\times}150{\times}1000mm$ dimensions were prepared. Three of which were strengthened with CFRP fabrics at the tensile side of the beams. Furthermore, a notch was cut at the center of the bottom surface for all of the studied beams. The notch was 15 mm deep and ran across the full width of tension side of the beams. The mentioned interfacial stresses could be calculated from strains measured using strain gauges mounted on the interface zone of the tensile concrete and the CFRP sheet. Based on the results obtained, it is shown that interfacial stresses developed between CFRP fabrics and RC beam had a noticeable effect on debonding failure mode of the latter. The load carrying capacity of CFRP strengthened RC specimens increased ~75% compared to that of the control RC beams. This was attributed to the enhancement of flexural mode of the former. Finally, finite element analysis was also utilized to verify the measured experimental results.
