In this study we analysed time allotment and the contents of a health textbook and its teacher's guide book of the 7th elementary curriculum. We intended to offer the basic data needed to establish the single health education. So the analysed results are as follows according to the health education model developed by the korean nursing association and health teachers' meeting and the teaching time allotment presented by the teacher's guide book. It's goal is practice in regular class time of the subjects for the time and contents of health education in the 7th elementary curriculum. The total class periods of health education of the 7th elementary curriculum are 229 hours and annual periods of health education per year are an average of 38 hours. The health education of the 7th elementary curriculum is separated into the 9 following subjects: Wise life, Pleasant life, Righteous life, We are 1st grade, Physical education, Science, Social studies, moral education and Practical course. The health education of the 6th elementary curriculum was combined with the units of physical education, but in the 7th curriculum it must be separated by a single, required health subject. The contents of health education of the 7th elementary curriculum is mostly dominated by units of community and environmental health with a total of 55 hours (24%). Therefore, the units of home health and social health, development of physical strength are fairly insignificant. The newly added contents in the 7th curriculum are "pregnancy and child birth, the protection and counterplan from rape, the reasons and prevention of stress, the reasons and the treatment of obesity, the damage of smoking and drinking, etc. According to the result above, we must establish the criteria for each year's health education in the 8th elementary curriculum. The contents of mental health, home health and social health should be revised and added new items. The health education that is separated in some subjects now must be established as a systematically integrated health education.

It is more likely that the degree of air quality degradation that we have faced would be much lessen, if integrated management of air pollution control and assessment had been fully enforced by the local administrations, not by the centralized environmental agency in the first place. As the selfgoverning local administrations have been established since 1995, the need for air quality control by the local administration or local agency is getting the ground. However, in practice, air quality control by the local administration rarely put into effect due to lack of basic data which cover the present trends of air quality in each local city or county and are necessary for decision making. The emissions of SO$_2$ in each city and county of Korea in 1993 were calculated in this study, based on energy consumptions and emission factors. The ambient concentrations of SO$_2$ also were estimated by applying modified Miller-Holtzworth model. Observed and estimated concentrations of SO$_2$ showed that about 17.5 percents of cities and counties in the country were more polluted than the target value, 20ppb/year. The emissions and ambient concentrations of SO$_2$ in each city and county in 2000, 2005, and 2010 were also forecasted, assumed business as usual senario. It was shown that, in 2010, the emissions of SO$_2$ will be 2.8 times more than those of 1993 and much of them are from industrial sector. Also shown that 38.3 percents of cities and counties will be more polluted than the target value and most of them are polluted areas in 1993. The methods and results of this study could be used in developing the efficient reduction strategies in each city and county.

Objectives: Public release of and feedback (here after public release) on institutional (clinics and hospitals) cesarean section rates has had the effect of reducing cesarean section rates. However, compared to the isolated intervention, there was scant evidence of the effect of repeated public releases (RPR) on cesarean section rates. The objectives of this study were to evaluate the effect of RPR for reducing cesarean section rates. Methods: From January 2003 to July 2007, the nationwide monthly institutional cesarean section rates data (1 951 303 deliveries at 1194 institutions) were analyzed. We used autoregressive integrated moving average (ARIMA) time-series intervention models to assess the effect of the RPR on cesarean section rates and ordinal logistic regression model to determine the characteristics of the change in cesarean section rates. Results: Among four RPR, we found that only the first one (August 29, 2005) decreased the cesarean section rate (by 0.81 percent) and continued to have an impact period through the last observation in May 2007. Baseline cesarean section rates (OR, 4.7; 95% CI, 3.1 to 7.1) and annual number of deliveries (OR, 2.8; 95% CI, 1.6 to 4.7) of institutions in the upper third of each category at before first intervention had a significant contribution to the decrease of cesarean section rates. Conclusions: We could not found the evidence that RPR has had the significant effect of reducing cesarean section rates. Institutions with upper baseline cesarean section rates and annual number of deliveries were more responsive to RPR.

HW/SW codesign is integrated design of systems implemented using both hardware and software components. Many design tools has been developed to support this new paradigm, so far. Current codesign tools are not widely used as been expected because of variety problems - rapidly evolving technology, platform dependency, absence of standard specification method, inconsistent user interface, varying target system, different functionality In this paper, we propose a web-based distributed HW/SW codesign environment to remedy this kinds of problem. Our codesign environment has object-based 3 tier client/server architecture. It supports collaborative workspace through session service. Fully object-oriented design of user interface(OOUI) enables easy extension without change of user Interface. Furthermore it contains transaction server and security server for efficient and safe transfer of design data. To show a validity of our design, we developed prototype of web-based HW/SW codesign environment called WebCEDA. Our model of HW/SW codesign can be used for web-based generic CAD tools.

There have been lots of researches for providing a personalized service to a customer using one-to-one marketing and collaborative filtering techniques in E-Commerce. However, there are technical difficulties for providing the recommendation of products far users, which often involve high complexity of computation. In this paper, we have presented an integrated method of classification problem solving method and constraint based configuration techniques. This method can reduce a complexity of computation by classifying a solution domain space that has a higher complexity of composition. Thereafter, we have modeled customers constraints and the components of products to configure a complete system by passing it to constraint processing module in Constraint Satisfaction Problems. Constraint-based configuration uses the constraint propagation using the constraints of buyers and the constraints among PC components to configure a proper product for a customer. We have transformed and applied vector space modeling method in the field of information retrieval to consider a customer satisfaction in addition to the CSP. Finally, we have applied our system to test data fur evaluating a customers satisfaction and performance of the proposed system.

This study investigated the causal relationships among the elderly, looking at social participation, depression, self-reported health, and life satisfaction. It was especially focused on the mediating effects of depression and self-reported health on the relationship between social participation and life satisfaction. From the 2006 Korean Longitudinal Study of Aging, data for 4,155 elderly over age 65 was analyzed with structural equations modeling with Amos 7.0 and sobel test. Major findings were as follows. First, social participation of the elderly has a negative influence on depression and a positive influence on self-reported health and life satisfaction. Second, self-reported health has a partial mediating effect on the relationship between social participation and life satisfaction. Third, the direct effect of depression on life satisfaction was not statistically significant, while the direct effect of social participation was significant. Therefore, depression was not proved as a significant mediator. This study tested the effects of social participation on depression, self-reported health, and life satisfaction empirically and confirmed the partial mediating model, in which social participation improves the elderly's self-reported health, which in turn improves the elderly's life satisfaction. These results suggest the importance of an integrated approach for the healthy and successful aging and the diverse types of social participation in an elderly person's quality of life.

This study explores the effectiveness and applications of event collection programs, which are integrated programs with event experience and collection experience as a cooperation model that combines school education and library resources as course-related materials. For the purpose, a triangulated analysis with both quantitative and qualitative data was conducted. As a result, This study examined an event collection program's effectiveness which were positive effects on the participated students' reading and perceptions on the roles of their school libraries. The event collection supported the students to self-construct their knowledge by exploring information with the provision of a collection with various materials on a topic, which would be hardly provided within the traditional library subject classification, and that the event collection program could be a useful tool for self-directed reading due to its promotion of interaction, sharing, and participation among materials and the participated students by functional factors of experiential marketing.

Atmospheric carbon monoxide (CO) and ozone $(O_3)$ play the important trace gases in tropospheric chemistry, through its concentration in the troposphere directly influences the concentrations of tropospheric hydroxyl (OH). Understanding the impact of CO and $O_3$ on the global tropospheric chemistry requires measurements of the global atmospheric CO and $O_3$ distributions. This study focuses on the identification of CO and O3 released in the East Asia between March 2000 and February 2004. During the period, the MOPITT instrument onboard the Earth Observing System (EOS)-Terra platform collected extensive measurement of CO. So we have used MOPITT data at 700hPa to analyze seasonal distribution of CO concentration. And the O3 measurements for this study were Total Ozone Mapping Spectrometer (TOMS) and Dobson spectrometer provided NASA/GSFC and Yonsei University, Korea. During springtime, the CO and O3 concentrations were increased over East Asia for April, May, and June. CO and O3 transport and chemistry in the springtime in East Asia are studied by use of the HYbrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model.
