Cardio-cerebrovascular diseases (CCD) account for 24% of the causes of death to Koreans and its proportion is the highest except cancer. Currently, the risk of the cardiovascular disease for domestic patients is based on the Framingham risk score (FRS), but accuracy tends to decrease because it is a foreign guideline. Also, it can't score the risk of cerebrovascular disease. CCD is hard to predict, because it is difficult to analyze the features of early symptoms for prevention. Therefore, proper prediction method for Koreans is needed. The purpose of this paper is validating IG-MLP (Information Gain - Multilayer Perceptron) evaluation based feature selection method using CCD data with simulation. The proposed method uses the raw data of the 4^th ~ 7^th of The Korea National Health and Nutrition Examination Survey (KNHANES). To select the important feature of CCD, analysis on the attributes using IG-MLP are processed, finally CCD prediction ANN model using optimize feature set is provided. Proposed method can find important features of CCD prediction of Koreans, and ANN model could predict more accurate CCD for Koreans.

This study was performed to investigate the biological activity of yangha flower buds as well as to manufacture of yanggeng prepared with various levels (0 g, 3 g, 6 g, 9 g, and 12 g) of yangha flower buds. DPPH and ABTS scavenging activities of yangha flower buds were 96% and 57% compared to levels of vitamin C, respectively. In the oxygen radical antioxidant capacity assay, antioxidant activity increased dose dependently up to $500{\mu}g/mL$ of yangha flower buds. There was no toxicity up to $1,000{\mu}g/mL$ in vascular smooth muscle cells, and yanggeng significantly reduced migration and proliferation by platelet-derived growth factor-BB-stimulated rat aortic smooth muscle cell migration and proliferation. In the sensory evaluation, the optimal sample was YY9, which was prepared with 9 g of yangha flower buds. It can be concluded that yangha flower buds show antioxidant and vascular protective activities. The optimal sample (YY9) is expected to contribute as a new functional food.

This study examined effects of 12 weeks of body weight based combined exercise training (resistance training for 30 min, aerobic training for 30min) on body composition (% body fat, lean body mass, fat mass and BMI (body mass index)) and cardiovascular factors (ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV)) in elderly women. A total of 32 subjects participated in this study, and were randomly divided into either exercise group (n = 16, EG) or control group (n = 16, CG). All variables at pre-test were analyzed by independent t-test for baseline test, and all data post the study period were analyzed by two-way repeated measures ANOVA with contrast testing (α = 0.05). Our results indicate that body composition (% body fat, lean body mass, fat mass and BMI) in both EG and CG do not differ significantly. However, the right and left sides of baPWV in EG was significantly reduced, as compared to CG. Taken together, these results indicate that combined exercise training for 12 weeks positively influences the cardiovascular factors, and may prevent cardiovascular diseases in elderly females (over 65 years), thereby resulting in increased quality of life for the elderly.

This study aims to provide basic data for maintaining and promoting health of obese middle-aged women who are interested in various chronic diseases such as cardiovascular disease and coronary artery disease by comparing and analyzing the effect on body composition and lipid metabolism through a 12-week Pilates mat exercise program for obese middle-aged women. This study targeted middle-aged women residing in Gyeonggi-do A, who are obese middle-aged women in their 40s and 50s with a body fat ratio of 30% or more, and had no regular exercise in the past three months. Obese middle-aged women(n=19) were divided into two groups, the Pilates mat exercise program group(n=9) and the control group(n=10), conducting exercise for 60 minutes three times a week for 12 weeks. As a result of analysis, the exercise group had a positive effect on body weight, skeletal muscle mass, body fat mass, body fat percentage, and BMI in body composition, but not in the control group. In the lipid metabolism, the exercise group had a positive effect on TC, TG, HDL-C, LDL-C, and FFA, but not in the control group. These results suggest that the 12-week Pilates mat exercise program conducted in this study is an exercise program that can prevent cardiovascular and chronic diseases in obese middle-aged women.

This study conducted to investigate incidence rate and association of serum lipid profiles with incidence of ischemic heart disease. Study subjects consisted of 417,642 adults aged 30 years and over, who underwent physical examination and responded to questionnaire from health examination center of 19 university general hospitals. Hazard ratio of risk factor for ischemic heart disease (IHD) were calculated by Cox's proportional hazard regression model adjusted for ages, BMI and lifestyle (drinking, smoking and exercising). For TC/HDL ratio, hazard ratio of IHD in male increased from 1.21 times to 1.84 times increase with TC/HDL ratio, and that in female also increased from 1.26 times to 1.86 times. For TG/HDL ratio, hazard ratio of IHD in male increased from 1.17 times to 1.49 times increase with TG/HDL ratio, and that in female also increased from 1.42 times to 1.97 times. For LDL/HDL ratio, hazard ratio of IHD in male increased from 1.26 times to 1.82 times increase with LDL/HDL ratio, and that in female also increased from 1.26 times to 1.68 times. In conclusion serum lipid indexes are the significant risk factors for cardiovascular diseases. The higher the concentration of TC, LDL and TG is, the lower the concentration of HDL is, hazard ratio for IHD increased. Ratio of TC/HDL, TG/HDL and LDL/HDL were also verified to be significant risk factors for IHD.

Purpose: This study was designed to identify the incidence risk of cardicerebrovascular disease (CVD) among male bus drivers, and to examine and compare the predictors of their health behavior according to the level of CVD incidence risk. Methods: The convenience sample of 222 male bus drivers were recruited from a bus company located in Jeonnam province. Data were collected from self-reported questionnaires and annual medical examination records from 2010. The CVD incidence risk was calculated based on the risk criteria for industrial workers. Results: The 26.6% and 26.1% of the participants were in the moderate and high risk group, respectively. The 72% of the participants were in the precontemplation stage and reported no intention to change their unhealthy lifestyles. Stepwise multiple regression analyses showed that current smoking, excessive alcohol drinking, physical inactivity and lack of knowledge were negative predictors of good health behavior in the normal/low risk group (Adj $R^2$=.443). Heavy alcohol drinking, current smoking, physical inactivity and dyslipidemia were reported by the moderate/high risk group (Adj $R^2$=.427). Conclusion: This study suggested that targeted education and counseling are needed to modify unhealthy lifestyles such as alcohol consumption, smoking and exercise among middle aged male drivers. Especially, dyslipidemia should be managed among those who are at risk for CVD.

This study was tested growth hormone and fatigue materials after eight-week high-intensity interval exercise to middle aged women (40's~50's women) who have been obesity without other disease. Two group of 20 candidates were randomly divided 10 persons as exercise group and control group. Exercise was conducted 8 weeks 4 days 35 minutes, before the study each group was checked vital sign for fatigue materials. It showed the following results. First, it has been increased growth hormone level after exercise program compared each group, significantly. Secondly, it has been decreased fatigue materials due to the high-strength interval workout for 8 weeks compared control as significantly. As a result, eight-week high-intensity interval exercise could be increased growth hormone levels by reducing fatigue and it might be preventing fatigue materials levels. We would suggest that high-strength interval workout for 8 weeks could have a positive effect for preventing and reducing fatigue and related disease, obesity.

Purpose: The purposes of this study were to review the research trends and to identify developmental direction of studies on community interventions according to the ecological model for workers with cardiovascular diseases (CVD) risk factors. Methods: Electronic databases including PsycINFO, PubMed, EMBASE, CINAHL, and Cochrane Library and the reference lists of articles were searched. All articles were assessed in relation to inclusion and exclusion criteria, resulting in 29 researches being reviewed. Each review was critically appraised by two authors using a guideline of PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses). Results: Nowadays, interventions in organizational level, integrated and web-based interventions are increasing to prevent CVD risk factors for workers. Even though the importance of psychosocial aspects to prevent CVD, the only 2 studies included psychosocial factors in the outcome variables. Also, 14% among 29 researches were based on theories. Conclusion: Psychosocial factors such as job stress, depression, and emotional labor could be CVD risk factors. Therefore, interventions including psychosocial aspects are needed to prevent workers' CVD risks more effectively. Theory-based interventions are needed to support interventions' effects and to develop the nursing science.
