This study divided a group of healthy adults aged 20 or older who had a health examination at J General Hospital in Gyeonggi Province into three groups according to the degrees of metabolic syndrome risk factors. They include the normal group (n=58), the pre-metabolic syndrome group (n=112) and the metabolic syndrome group (n=32). They were compared in exercise capacity and cardiac structure and function and impacts of exercise capacity on the cardiac diastolic function. All the groups took echocardiography to have their cardiac structures and functions examined and an exercise stress test to have their exercise capacity measured. The research findings were as follows: There were differences in exercise capacity, cardiac structure, and diastolic heart function among three groups. Between exercise capacity and diastolic heart function was found to be related. It turned out exercise capacity affected the cardiac diastolic functions. In conclusion, there were significant differences in exercise capacity between the normal group and the metabolic syndrome group and in the cardiac structure and function among the normal, metabolic syndrome, and pre-metabolic syndrome group. In addition, METs (metabolic equivalents) and heart rate recovery of exercise capacity turned out to affect cardiac diastolic functions.

Purpose: This review examined literature relevant to adolescent's health behavior in order to identify key behaviors and factors related to health behaviors for targeting health promotion interventions. Method: A critical review of 29 research articles was carried out using the guidelines suggested by Cooper. Result: The majority of the studies were descriptive and cross-sectional. Generally. the study includes sub-dimensions such as general hygiene and daily life habit, safety and accident prevention, nutrition and eating (tobacco, drinking), exercise, mental health and stress management, health duty (drug, health examination, disease prevention). Factors highly related to health behaviors were age, living areas, economic status, parent health behaviors, parent health concern, social support, friends influence, self-efficacy, self-esteem, locus of control, and the perceived health status. Sex, parent education and health knowledge were not related to health behaviors of adolescents. Conclusion: Several conceptual and methodological problems were identified in the studies review, such as restricted conceptualization of health behaviors and sampling issues which limit the generalizability of the study outcomes. Further research is needed to enhance the concept clarification and generalizablity of the study results.

Purpose: This study was to investigate factors influencing the Framingham risk score-Coronary heart disease (FRS-CHD) according to gender and body mass index (BMI) of adults who participated in the 5th Korea National Health and Nutrition Examination Survey (KNHANES V-3). Methods: This study used a cross-sectional design with secondary analysis with KNHANES V-3. The FRS-CHD scores were measured with ages, sex, blood pressure, cholesterol, high density lipoprotein, smoking, and diabetes mellitus. With demographic characteristics, family history of ischemic heart disease, types (intensity) and days of physical activities, perceived stress, drinking, menopause (in female), and BMI scores were measured. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. Results: FRS-CHD was significantly associated with types (intensity) and days of physical activities, educational level, occupation, and marital status, explaining 19.1~76.8% of the variance in men. FRS-CHD was significantly associated with types (intensity) and days of physical activities, menopause, and education level, explaining 55.0~59.5% of the variance in women. Conclusion: Factors influencing FRS-CHD were significantly different according to gender and BMI. To reduce the risk of coronary artery disease, it is necessary to develop gender-specific physical activity programs according to BMI.

Lightweight metallic truss structures with open, periodic cell are currently being investigated because of their multi-functionality such as thermal management and load bearing. The Kagome truss PCM has been proved that it has higher resistance to plastic buckling, more plastic deformation energy and lower anisotropy than other truss PCMs. The subject of this paper is an examination of the failure mechanism of Wire woven Bulk Kagome(WBK). To address this issue, the out-of-plane compressive responses of the WBK has been measured and compared with theoretical and finite element (FE) predictions. For the experiment, 2 multi-layered WBK are fabricated and 3 specimens are prepared. For the theoretical analysis, the brazed joints of each wire in WBK are modeled as the pin-joint. Then, the peak stress of compressive behavior and elastic modulus are calculated based on the equilibrium equation and energy method. The mechanical structure with five by five cells on the plane are constructed is modeled using the commercial code, PATRAN 2005. and the analysis is achieved by the commercial FE code ABAQUS version 6.5 under the incremental theory of plasticity.

The purpose of this study was to determined the rate of sensitization to food allergen in children with Atopic Dermatitis (AD) in Korea. A total of 3,783 patients (male = 1983, female = 1800) with AD (age under 18 years) who had visited Samsung Medical Center from 1998 to 2003 were enrolled in the study. Food hypersensitivity was measured by specific IgE to egg, cow's milk, soy, peanut, wheat, buckwheat, beef, pork, chicken, shrimp, crab, salmon, mackerel, etc. Specific IgE levels > 0.7 kU/L. by Captured Allergen Product (CAP) assay were considered positive. Chi-square test at p value < 0.05 was used to examine the difference of the prevalence by sex and age. The rate of sensitization to multiple food allergens was 31.2% and decreased with age. Hypersensitivity to egg showed highest prevalence, which was 24.3%, compared to the prevalence of other foods. High prevalence of hypersensitivity to milk. wheat, soy, peanut, crab or shrimp was observed (11.6- 17.7%). Low prevalence of hypersensitivity to beef, pork, tuna or chicken was observed (1.9-3.5%). Children aged under 3 years had significantly higher prevalence of hypersensitivity to egg, milk, soy and beef than children aged at least 3 years. Our results stress the need for examination of food hypersensitivity aimed at identified and limited each food allergen among children with AD caused by food to help patients outgrow their food allergy.

The pivotal emphasis of the physical training for the security agents of the security headquarters in the North Korea is to inspire them with the defense physical training-centered ideology and the war spirit. Their special martial arts is the protectee-centered offensive arts rather than the self-centered arts. It puts emphasis on training black belt-holders in diverse martial arts rather than in a certain martial art. Thus, the physical training for security agents in the South Korea should be also developed into the ways to rear them as black belt-holders in diverse martial arts rather than to foster them as high grade-holders in a certain martial art. And also, professors majoring in security and physical science have to develop jointly the measures to improve the physical and mental agility and the basic physical strength to inspire rapid handling and perseverance, to develop the physical training program to reduce mental and physical stress of security guards, to develop the standard for the examination of physical strength suitable for the body figures of Korean people and the regular evaluation with the standard and to apply traditional folk-games such as the swing and the seesaw to the physical training for security guards.

Purpose: Most research on risky drinking among adults in Korea has focused on problem drinking and high-risk drinking. This paper examines the nature of heavy episodic drinking_(HED) among adults and seeks to identify the risk factors for HED by analyzing differences by gender and age. Method: Participants were 3,886 adults aged 19-64 years from the database of the fifth Korean National Health and Nutritional Examination Survey (KNHANES-V, 2010). Data were analyzed by conducting the Rao_Scott chi-square test, an ANCOVA, and logistic analysis with SAS 9.2. Results: Individuals between 19 and 29 years of age had the highest HED among all age groups. Individuals between 40 and 49 (male adults) and those between 30 and 39 (female adults) showed HED associated with stress, suicidal ideation, smoking, and other health behavior-related variables. Risk factors that affected HED in male adults were age, educational status, and current smoking, while for female adults, the factors were age, educational status, employment, marital status, and current smoking. Conclusions: It is necessary to develop appropriate intervention programs that abate negative emotions and lessen the risk of HED in adults with consideration to gender and age differences.

The purpose of this study is to investigation the eating habits and health-related behaviors of adolescent students. 700 students are randomly selected in 6 high schools in Chunchon area. The most students take three meals a day. but most of girl students take less two meals a day or often go without a meal. There are the tendency that boy-students are more satisfied with their meal habits, but they have the health problems caused by irregular meals. There are more boy-students have the regularity of meal habits than girl students. and the former have the more tendency of going without a meal than the later which shows that girl-students have to give more attention to their health management. Their sleeping hours are not enough to recover the tiredness. The higher grads they are in the less time they have to take a rest. The tenth grads students are shown to feel the most serious stress. but have few opportunities to take a medical examination, which means that we have insufficiency of health education as a precautionary measures. Accordingly, it is important that teachers have to provide students with education of good meal habit which is fit to their real life. In modern times, as there are the tendency that more women participate in the social activity. we will reinforce the education that the boy-students may take active part in the health management without distinction of the roles between boy and girls-students.
