Purpose: The purpose of this study was to describe and understand elementary school health teachers' role perception in their own perspectives. Methods: Data were collected from three focus groups composed of five participants for each group. Each focus group had an interview for two and a half hours on the average. The main question was "What is your perception on the roles of health teachers in elementary schools?" Qualitative data from transcribed notes and field notes were analyzed using qualitative content analysis. Results: Five main roles were identified from the participants. The participants perceived themselves as 'an expert of health education in school and community', 'a health service provider for school members', 'a health guardian for school members, the coordinator of healthcare related works in school, and the leader of school health. Conclusion: The participants have multiple role identities, which are very important for health management of school members. And the roles such as an expert of health education and a leader for school health are recently emphasized. The findings of this study can provide useful information to design orientation programs for newly appointed health teachers and continuing education programs for enhancing role performance of health teachers in elementary schools.

This study aims to develop a rational evaluation system which consists of the selection of evaluation items and the estimation of its weight for the Enhancement Program of the Quality of Life for Farmers and Fishermen and Rural Development. This system has two hierarchical steps. The first step shows the evaluation goals which are relevance, efficiency and effectiveness of the program. The second step stands for the evaluation items which have 11 sub-items such as necessity and externalization for the program, rationality of procedures, feedback and monitoring system, budgetary allocations, information activities, impacts on the program, achievements of the goals and so on. A tentative evaluation system was proposed by brainstorming and Delphi method of expert-group. Weighting values of evaluation items were calculated through pair-comparison works of expert group using stepwise matrix sheets by AHP(Analytic Hierarchy Process).

In this paper we mention the optimization of MPEG-4 VM (Moving Picture Expert Group-4 Verification Model) GA (General Audio) AAC (Advanced Audio Coding) encoder and the design of the decoder for PDA (Personal Digital Assistant) using MPEG-4 VM source. We profiled the VMC source and several optimization methods have applied to those selected functions from the profiling. Intel Pentium III 600 MHz PC, which uses windows 98 as OS, takes about 20 times of encoding time compared to input sample running time, with additional options, and about 10 times without any option. Decoding time on PDA was over 35 seconds for the 17 seconds input sample. After optimization, the encoding time has reduced to 50% and the real time decoding has achieved on PDA.

The need for evidence-based decision making in immunization programs has increased due to the presence of multiple health priorities, limited human resources, expensive vaccines, and limited funds. Countries should establish a group of national experts to advise their Ministries of Health. So far, many nations have formed their own National Immunization Technical Advisory Groups (NITAGs). In the Republic of Korea, the Korea Expert Committee on Immunization Practices (KECIP), established by law in the early 1990s, has made many important technical recommendations to contribute to the decline in vaccine preventable diseases and currently functions as a NITAG. It includes 13 core members and 2 non-core members, including a chairperson. Core members usually come from affiliated organizations in internal medicine, pediatrics, obstetrics, microbiology, preventive medicine, nursing and a representative from a consumer group, all of whom serve two year terms. Non-core members comprise two government officials belonging to the Korea Centers for Disease Control and Prevention (KCDC) and the Korea Food and Drug Administration. Meetings are held as needed, but at least twice a year, and sub-committees are formed as a resource for gathering, analyzing, and preparing information for the KECIP meetings. Once the sub-committees or the KCDC review the available data, the KECIP members discuss each issue in depth and develop recommendations, usually by a consensus in the meeting. The KECIP publishes national guidelines and immunization schedules that are updated regularly. KECIP's role is essentially consultative and the implementation of their recommendations may depend on the budget or current laws.

Purpose: The Purpose of this study was to build up guidelines for preventing constipation in the Korean elderly based on the National Guideline $Clearinghouse^{TM}$ Guideline. Method: The process is composed of four steps: first. the composition of an expert group; second, the evaluation by the expert group about the appropriateness and applicability of each recommendation in the guideline; third, systematic literature review for evidence searching; and fourth. the formation of guidelines for Preventing constipation in the Korean elderly according to experts' opinions and literature review. Result: The appropriateness and applicability of each recommendation showed high scores, but the score of applicability was lower than that of appropriateness. The reasons for lower score of applicability were lack of cognition on the importance of constipation management and lack of recent information and evidence-based knowledge on constipation. There were some inadequate recommendations in Korean clinical setting. So the modified and replaced recommendations were added to the guidelines for preventing constipation in the old adult population to improve the applicability in Korea. Conclusion: The results of this study can be used as fundamental baseline data for future study to develope guidelines for management of constipation in the elderly and will be adapted locally for Korean clinical setting.

These days, one of the issues well discussed is the obstruction or screen of sight to mountain-skyline by buildings. So question is to which heights buildings should be constructed over mountain-skyline and then harmony can be realized between mountain-skyline and building-outline. Based on the mentioned above, this study intends to find out the proper projection- level of buildings over background mountain-skyline when considering the types of mountain-skyline, building-outline and building-layout. The results of this study are first, the proper projection-ratio of buildings over background mountain-skyline can be 0.1 because assessment values on harmony-level are more than 3.0 in almost cases, second, the building-outline influences on the assessment values of harmony-level when the types of mountain-skyline are formed left-high & right-low and right-high & left-low, third, building-layout doesn't influence on the assessment va lues of harmony-level, finally, statistically difference doesn't exist between expert group and non-expert group in the assessment values of harmony-level.

In this paper, MPEG2(Moving Picture Expert Group 2) image data video decoding technique is presented, it is Huffman decoding method and fractal image method which is very complexive algorithm and have too much times to implement this method. This have defect of overlap decoding and transport work because of impossible to represent objective value of resemblance. The proposed method was calculated the mathematical absolute image resemblance and simplify the moving picture process to reducing the step of moving picture codefying. The results show that smoothed moving picture compared recent methods.
