Objective: In order to provide basic data required to evaluate the knowledge and behavior of old people towards health promotion and primary factors that influence them, to develop a health educational program. Method: A survey was conducted from March 6th 2004 to June 10th 2004. A total of 949 senior citizens over 60 participated in the survey. Results: The old people was the lower the educational level they had, the lower the level of health education experience they had and the lower the frequency of regular health check-ups they had. In regards to health education and health promotion, seniors citizens were neglected because of a lack of health awareness and knowledge, wrong habits related to healthy living, low access to medical examination, poor economic state, and low educational level. In addition to social atmosphere and systematic efforts by the government, senior citizens tried to find their own ways to have healthy living by improving their educational level, health awareness, and level of health knowledge, and lifestyle. Conclusion: Therefore, not only their family members, but local communities, public organizations, and the whole nation should make every effort to provide a effective health education system by using health educators for senior citizens. There is also a need to prepare a practical and systematic health education program for senior citizens so that they can enjoy comfortable and healthy living in their old age.

Based on the theory of planning behavior, the purpose of this study was to validate the path to consumers organic bakery product purchasing process, and moderating effect of price sensitivity. The improvement of national income and changes in diet due to economic growth began to increase consumption of organic and eco-friendly farm products, and thus products using organic materials began to be released in bakeries. Thus, it was necessary to understand consumer awareness and purchasing processes for organic bakery products. Specifically, the study examined the structural relations among purchase reasons, purchase motives, and purchase behavioral intention of organic bakery products. A survey was conducted in May 2019 from adults who had experience purchasing organic bakery products in Seoul metropolitan area, and 327 responses were used for data analysis. The findings of the study showed that consumers' interests in health, food safety, and environment had positive effects on their attitudes, subjective norm, and perceived behavioral control toward organic bakery products, while their interests in organic products did not have an effect on perceived behavioral control. There were significant differences in the purchasing process of organic bakery products according to their price sensitivity. The study suggests that the correct delivery of information on organic ingredients and the price policies available to many consumers will contribute to the revitalization of organic bakery products.

The conventional brace system is generally accepted as the lateral load resisting system for steel structures due to efficient story drift control and economic feasibility. But lateral stiffness of the structure decreases when buckling happens to the brace in compression, so that it results in unstable structure with unstable hysteresis behavior through strength deterioration. Buckling restrained brace(BRB) system, in which steel core is confined by mortar/concrete-filled tube, represents stable behavior in the post-yield range because the core's buckling is restrained. So, seismic performance of BRB is much better than that of conventional brace system in point of energy absorption capacity, and it is applied the most in high seismicity regions as damper element. BRBs with various shaped-sections have been developed across the globe, but the shapes experimented in Korea are now quite limited. In this study, we considered built-up type of restraining member made up of precast reinforcement concrete and the steel core. we experimented the BRB according to AISC(2005) and evaluated seismic performances and hysteresis characteristics.

Objectives： The rate of adolescent smoking is important because lead to adult smoking. And early onset of smoking is associated with chronic disease in adult life. The purpose of this study is to describe the smoking status of adolescents and identify the risk factors for smoking in each school. Methods： We selected the participant schools that are located in Yang-cheon Gu, Seoul, Korea, considering the social economic status. The subjects were included 719elementary school students,1,251 middle school students and 1,513 high school students. Self-reported questionnaires were administrated between December 16 and December 24 , 2002. Students were informed in writing that the survey was voluntary. The response rate was 98.7, 81.1 and 95.4 in elementary, middle, and high school, respectively. Results： The results of this study were as follows： 1) Students who have attempted to smoke were 8.8% in elementary school, 29.3% in middle school and 35.0% in high school. 2) The current smokers were 2.0%, 7.9% and 11.5% in elementary, middle and high school, respectively. 3) In elementary school, smoking of mends and physical health were significantly predicted the attempt to smoke. Stress, smoking of mends, alcohol, and binge drinking were associated with the attempt to smoke of middle school students. In high school, the attempt to smoke was related to gender, maternal education, depression, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking. 4) Current smoking was associated with smoking of mends and binge drinking in middle school and gender, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking in high school in multiple logistic regression. Conclusion： There is a need for health education and specific strategies to help adolescents prevent from smoking. Smoking prevention programs which include risk-taking behavior such as alcohol, method of copying with stress, and supporting environment were required.

For economic and technical reasons, it is difficult to obtain high quality undisturbed cohesionless samples, hence most researchers rely on preparing remolded and reconstituted representative samples of sandy soils. In this study, moist tamping, air pluviation, and dry deposition methods were applied to make remolded samples at similar relative densities. A series of isotropically consolidated drained tests were conducted with accompanied by measured elastic wave velocities in order to evaluate a difference between sample preparation methods and relative densities. For the elastic wave velocity measurements, piezoelectric elements were installed on the top and bottom cap of the triaxial device. The results showed that soil behavior relies on sample preparation methods, and that the trend of shear wave velocity was the same with volumetric strain behavior.

Pipe-rack structures supporting high temperature and pressure are of great importance to ensure the safety of the operation of the plants. If some damage occurred in the pipe-rack structure, the facilities not only bring damage to the commercial property, but also result in economic losses. Specially, since pipe-rack structures are exposed to various environmental conditions, it is essential to evaluate the thermal behavior of the structure caused by environmental conditions for the appropriate design and maintenance of the pipe-rack structure. Thus, based on a selected, typical pipe-rack structure, a thermal-stress coupled analysis was conducted to evaluate the temperature distributions and thermal stresses of the structure. For this, this study accounted for the operating condition of the pipe and the effect of environmental conditions, Yeosu in South Korea and Saudi Arabia in the Middle East. The results of the study showed the need for accounting for a variance in the environmental factors to evaluate the thermal behavior of the pipe-rack structure along with the working condition of pipe.

This study investigated the differences in health behaviors of adolescents depending on their sexual experiences. Secondary data analysis was conducted using the data of 61,861 respondents from the 2017 adolescents' health behavior online survey in Korea. Adolescents with sexual experience were typically male, in high school, from a boy's school, had low academic performance, lived apart from their parents, and of either high or low economic status; their health behaviors were characterized by more physical activity, stress, sadness and hopelessness, thought/planned/attempted suicide, drinking, and smoking. Almost half of adolescents with sexual experience (48.9%) did not use contraception. The results of this study are significant and can contribute to the development of sex education programs when considering the characteristics of Korean adolescents and their sexual health.
