Purpose: This study was undertaken in order to determine factors affecting health promoting lifestyle of elderly women. Method: The subjects were 299 elderly community residing women over the age 65 living in 2 large cities. The instruments used for this study were a survey of general characteristics, health promoting lifestyle(47items), perceived health status(6 items), self-efficacy(l7 items), and social support(18 items). The data was analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and Stepwise Multiple Regression. Result: The result of the study are as follows: The average item score for the health promoting lifestyle was 2.46, the highest score on the subscale was interpersonal support(M=2.83). A significant difference between age, education level, income, experience of smoking, alcohol, exercise, and health promoting lifestyle were found. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting lifestyle was social support(55%). Conclusion: Social support accounted for 54% of the variance in health promoting lifestyle in the elderly women. Therefore, health promoting programs that increase social support should be developed to promote a healthy lifestyle of the elderly women.

Purpose: The purpose of this study was to identify the moderating and mediating effects of self-leadership in the relationship between organizational culture and nurses' informatics competency. Methods: Participants in this study were 297 nurses from the cities of Busan and Ulsan. The scales of organizational culture, self-leadership and informatics competency for nurses were used in this study. Descriptive statistics, Pearson correlation coefficient, stepwise multiple regression were used for data analysis. Results: Nursing informatics competency of the participants was relatively low with a mean score 3.02. There were significant positive correlations between subcategories of perceived organizational culture, self-leadership and nursing informatics competency. Self-leadership was a moderator and a mediator between organizational culture and informatics competency. Conclusion: Based on the results of this study, self-leadership promotion strategies to improve nursing informatics competency are needed.

This study proposed a plan to seek a more practical way of life norm education of today's families on the basis of family rule in the traditional society by comparison between the older generation's family life rule education and college students. The study was made by analysing rules in Chosun Dynasty questionaire nair was drawn up on the basis of it. The subjects of this study were college students of one largest cities and their 800 parents. Collected data was processed by frequency analysis, ANOVA, interrelation and regression which are used through SPSS computer programs, Study results show that acceptance level is higher among the older generation but the necessity of family standare education is urgent beyond the generations. Also people who have lived with grand parents feel more necessity of education family norm. When the education could not be made in families because parents excessive protection examination-centered education, and bad effects of mass media then emphasis has to be made to create life culture which makes family norms to be kept continuously by the education at schools, education culture centers and public facilities.

This study has investigated the perception of adults in relation to healthy family to help identify import issues. Gathered information were then incorporated to education programs for the Healthy Family Support Center. For this purpose, a survey was conducted in four cities in Kyungnam during March 2007. The responses of 213subjects have been used for the final analysis. The results of this analysis lead to three major findings. Firstly, the surveyed adults regarded positive interaction and domestic family functions as essential activities in healthy families. Secondly, the participants exhibited a very low knowledge-level of the 'Healthy Family Act', and the Healthy Family Support Center. Finally, the respondents said that they are more likely to specifically participate in educational program and counseling program if it helps them prevent family programs.

The Purpose of this study was to define the School Health Education Concepts, to establish the learning objectives and contents for school health education, and to diagnose the phenomenal aspects related to current school health Education in Korea. The results of its diagnosis indicated that the Education Ministry had never had any open opportunities for the teachers to get health education licence, and. universities had never issued health education teacher′s licence to the perspective students in Korea. Under such condition, there was "Korean nursing teacher′s association" for school health education, which had lectures, for two to three years, in order to learn how to develop, teach and evaluate the school health program. Currently, School boards in cities recommended that all nursing teachers should teach school health education in classes for six hours in a week without any fixed health program. Also, There was only "Korean Society for Health Education" for the purpose of dealing with school health education, which had been publishing annual journal. This study demonstrated how to develop school health education curriculum, which composed of the methods for needs assessment and PRECEDE Model(Predisposing, Reinforcing, and Enabling Causes in Educational Diagnosis and Evaluation).

Most distance functions, including taxicab distance, are defined on Cartesian plane, and recent studies on distance functions have been mainly focused on Cartesian plane. However, most streets in cities include not only straight lines but also curves. Therefore, there is a significant need for a distance function to be defined on a curvilinear coordinate system. In this paper, we define a new function named polar taxicab distance, using polar coordinates. We prove that this function satisfies the conditions of distance function. We also investigate the geometric properties and classifications of circles in the plane with polar taxicab distance.

Everything in the world is becoming connected and interactive due to the Internet. The future of interactive smart environments such as smart cities, smart industries, or smart farms demand high network bandwidth, high network flexibility, and self-organization systems without costly hardware upgrades, and they provide a sustainable, scalable, and replicable smart environment backbone infrastructure. This paper presents a new Hybrid Software-Defined architecture for integrating Internet-of-Things technologies that are essential technologies for smart environments. It combines a software-defined networking infrastructure and a real-time distributed network framework with an advanced optimization to enable self-configuration, self-management, and self-adaption for providing seamless communication and efficiently managing a vast number of smart heterogeneous devices.

It has been a long time that black smoke emitted from buses and trucks powered with diesel engines, especially city-buses, came to be a serious air pollution problems in large cities as Seoul and Pusan. Therefore, proper means to reduce black smoke from diesel engines have to be considered as soon as possible, because it will take quite a long time to replace major passenger transportation system in cites from city-buses to subway. This paper, as a study on the reduction of diesel black smoke, showes how the black smoke of diesel engines can be reduced at various loads and engine speed by supplying small amount of gaseous fuel as LPG into the intake manifold. Thermal efficiency has been also considered for users, and confirmed through the engine test.
