The health center has to play an important role in promoting community health and satisfying a variety of community health needs and demands in the decentralized Korea. The nearly enacted Community Health Act compels every health center to make its own health plans which intend to deal with local health problems and plan its future health care. This obligation is obviously a big burden to most health centers. They do not have experiences in and abilities of making local health care plans. In order to establish a systematic community health plan, health centers have to concentrate their efforts on enhancing the ability of making health care plan through gathering and analysing the local health informations. However, it is very difficult in reality. This is simply because it will take long time to accomplish these activities. It seems natural that various professionals and researchers participate in carrying out the process of making community health plan in the initial stage. No standardized methodology and analysing framework exist even in the health professional society. Nonetheless, it is common to introduce survey research methodologies in analysing consumer's health care utilization and cost, and in identifying factors influencing health behaviors. Many researchers and professionals have applied social survey methodologies in obtaining information on providers and health policy makers as well. The authors have found that few studies have ever utilized local health data stored at the self-employed medical insurance society as the data source of planning activities. The purpose of this study is to illustrate the usefulness of the data stored at the Sung-Dong Gu Self-employed Medical Insurance Society in establishing the community health plan. The major contents of this study are as follows ; 1. frequency of utilization by age, area, sex, type of medical care institutions, and some major diseases 2. Medical treatment by type of medical care institutions, by classification of 21 diseases, by frequency of three-character categories 3. Medical treatment of major neoplasm and some chronic diseases by age, sex, and area. The conclusion of this study is that it is of great potentiality to find out the local health problems and to use them in blueprinting the community health plan through comparing the frequency of medical utilization analyzed by a variety of variables with NHI health data or the health data from survey research.

The purpose of this paper is to suggest the improving plans about the system as searching an effective managing devices for NEIS with analysis of managing condition. For the plans, questionnaire was performed in the five sections to primary and secondary school teachers. Those were recognition about C/S, Introduction and conductive processing of NEIS, Satisfaction of specific task on school affairs and educational matters, its function, efficiency and security as well as technical problem. Those were recognition about C/S, Introduction and conductive processing of NEIS, Satisfaction of specific task on school affairs and educational matters, its function, efficiency and security as well as technical problem. The results are following: First. in spite of satisfaction with function of C/S, it have been some problems such as frequent patch and down of server. Secondly, although the introduction of NEIS was done in hurry without gathering teachers' opinions and sufficient research of system, it has been expected to settle down normally with correction and security. Thirdly, positive reaction was generally showed in research on satisfaction of specific task for school affairs and educational matters. Fourthly, most of teachers have known the functions of NEIS and recognized its convenience. Although they has not thought it reduced their work, they have realized it's convenient for dealing with statistics. Lastly, they think of NEIS as the essential system for the age of information, in spite of problems such as reveal of personal data and security. Therefore, we should keep eyes to problem of an invasion of human right. In addition, study deep into NEIS should be conducted with consistent security for the system. In order to it. technical and legal system should be carried out side by side.

In this essay, following final conclusions have been drawn by analyzing medical ideology and research system of Yi cheon in Yi hak yip mun("醫學入門"). Firstly, even though the existing medical history researchers are not noting the system of Yi-cheon's medical ideology, this essay has proved the man as a doctor who succeeded the (main system) based on the content of Yi-hak-yip-mun("醫學入門") by Ju-Dan-Gae(朱丹溪). The outline of this proof is as follows. 1. Those doctors who had actively researched in Myung era(明代), were basically taking over the medical studies and result of Gum-Won era(金元代). However, depending on whose theory is to be followed, the followers are largely divided into two groups of Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派). In addition, both Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派) hold contradictory ideologies to that of the main medical system. In Yi-hak-yip-mun("醫學入門"), Yi-cheon(李?) ties The Text of Whang-Jae-Nae-Kyung("黃帝內經"), Jang-Jung-Kyung(張仲景), Yu-Ha-Gun(劉河間), Yi-Dong-Won(李東垣), Ju-Dan-Gae(朱丹溪) into one pedigree. With regard to the main system, he especially marks Ju-Dan-Gae(朱丹溪) for his efforts in gathering various medical theories into a large compilement. 2. When Yi-Cheon(李?) was writing Yi-Hak-Yip-Mun("醫學入門"), he made references to various medical publishings, among those book which he had utilized, books by Ju-Dan-Gae Academics(丹溪學派) had affected him more than anything else in terms of both quality and quantity. 3. Yi-Cheon(李?)'s "Congested Phlegm Theory(痰鬱論)" had succeeded "Congested Phlegm Theory(痰鬱論) of Ju-Dan-Gae Academics(丹溪學派). His Yi-Hak-Yip-Mun("醫學入門"), carries a more complete form of "Congested Phlegm Theroy(痰鬱論) which was made into a more systemic and widely applicable method which was by Ju-Dan-Gae Academics(丹溪學派). Secondly, Yi-Hak-Yip-Mun("醫學入門"), is a medical book which was written in the process of systemic reorganization of medical theories of various academic parties in Myung 명 era. Since this process was hearing its completion in the period of Yi-Cheon(李?), he chose specific ways of reshuffling, whilst seeking ways to efficiently utilizing existing medical information . He provided a standard to specific ways. He rearranged the existing medical theories based upon these standards. He also contributed to clinical medicine by providing description of symptoms focused upon the symptoms differentiated In Conclusion, Yi-Hak-Yip-Mun("醫學入門") holds systematic medical information which was developed by Ju-Dan-Gae Academics(丹溪學派). Also, Yi-Cheon(李?) uniformly classified the clinical experiences of existing Ju-Dan-Gae Academics(丹溪學派). He had contributed in the clinical use of Ju-Dan-Gae Academic(丹溪學派)'s clinical experience by providing main points from differentiation of symptoms.

Anchovy scoop nets, a kind of lift net have been used in the coastal area of Cheju and South sea of Korea. An incandescent lamp(AC 100V, 1kW) is being used as a fishing lamp for gathering anchovy. Fishing lamp was installed at 1m ahead of the prow and 1.5m higher than the water surface. The fishing lamp let fish school rise to the water surface and attract to bag net. Accordingly, a successful anchovy catching depends on controling of fishing lamp. On the study, the distribution of spectral irradiance illumination of incandescent lamp(1kw) and the irradiance efficiency of reflection plate were analyzed and discussed to investigate the ability of fishing lamp which can attract anchovy school effectively. The results obtained are summarized as follows : 1. Around 180% of irradiance efficiency of incandescent lamp was increased by using the reflection plate. The light of lamp was radiated into water with circular shape. 2. The irradiance illumination of incandescent lamp in air was a maximum in wave length of 994nm but it was 690nm at 0.5m and 1.0m of water depth. 3. The relationship between water depth(x) and water illumination(y) of vertical light is represented as follows : y=146.03e supper(-0.37x) 4. The light of incandescent lamp(1kW) pass through much better into vertical direction than horizontal but it was estimated that the light was not able to reach depth of 20m.

Article 36 of the Building Code Enforcement Ordinance requires that an exterior evacuation stairs be installed for the buildings of three stories and over with cultural facilities or gathering places which have over $1,000\;m^2$ floor area of public performance halls or recreational facilities. The concentration of population together with the increase of high-rise buildings in cities call for various precautionary measures to be taken against human disasters. For the past ten years high-rise buildings showed 85% of increase, marking a steep rise. This increase of high-rise buildings may lead to human disasters in urban areas and, in case of fire breakout, may cause great loss of human lives and property damages. The most difficult fire-fighting activities in high-rise building fires are those of evacuation. Because smoke spreads through the upper floors, the securement of evacuation route in high-rise buildings may be the only way to minimize loss of lives. In high-rise buildings exterior escape stairs are necessary because it is difficult to secure evacuation route with only direct stairs or interior stairs. The Building Code now in force provides insignificant coverage on the exterior evacuation route installment and therefore becomes an inadequate means for evacuation route securement in high-rise building fires. To compensate for this inadequacy the Building Code should be revised to include a mandatory clause that an exterior evacuation stairs be established for the buildings of ten stories and over which can be categorized into high-rise building group.

In order to investigate the possibility of wine-making with the grape variety cultivating in Korea, the basic analysises were carried out; analysis of the grape maturity during ripening period, the composition of grape juice, and the chemical components of wine from different varieties. Also the yeasts existing naturally on the grape were isolated and identified. For the selection of strain, the characteristics of 6 strains were studied. The results obtained were summarized as follows. 1. The reducing sugar content increased considerably during two weeks after the ordinary grape-gathering period. 2. The sugar content was highest in Muscat bailey A, which could be fermented naturally. The other varieties, Campbell Early, Steuben, and Alden needed chaptalisation for wine-making. 3. The permanaganate number and the methanol content of wine from all varieties were lower than french wine. 4. The sensory evaluation of wine showed that the pink wine was appreciated better than the red wine of same variety and the foxy taste of wine from hybrid grape influenced little to Korean. 5. The selected 6 strains were identified as Saccharomyces chevaliers, Saccharomyces capensis and Saccharomyces globosus. The strain No. 3 and No. 4 showed the most excellent characters for wine-making.

One of the main objectives of National Assessment of Educational Achievement (NAEA), which is implemented by Korea Institute of Curriculum and Evaluation(KICE), is to manage the qualities of National Curriculum. Thus we considered NAEA as the research for educational program assessment and tried to find out how to make NAEA better for achieving that objective. For the purpose of this paper we analyzed the present conditions of NAEA into four perspectives. And then according to each perspective we explored schemes for improving NAEA. In conclusion, we proposed the following; Firstly, in relation to assessing students' understanding of the mathematics contents, the meanings of Achievement Levels have to become much more clear and concrete. in relation to assessing for comparing student' understanding according to mathermatics content areas, the number of items has to be increased for elevating validities of NAEA. Thirdly, in relation to gathering the information about properties which are shown by the students in particular Achievement, it is necessary to think about how to produce items for the purpose in the step of developing items in NAEA. Finally in relation to collecting the data which can be useful for relevance of mathematics contents, it is necessary to make a special group of items for identifying relevance of mathematics contents, and to apply performance assessments on part of the students, not whole students.

This paper shows alternative route search and preference route search for the traffic route search, and proposes the use of the fuzzy non-additive controller by the application of AHP(analytic hierarchy process). It is different from classical route search and notices thinking method of human. Appraisal element, weight of route is extracted from basic of the opinion gathering for the driving expert and example of route model was used for the finding of practice utility. Model evaluation was performed attribute membership function making of estimate element, estimate value setting, weight define by the AHP, non additive presentation of weight according to $\lambda$-fuzzy measure and Choquet fuzzy integral. Finally, alternative route search was possible to real time traffic route search for the well variable traffic environment, and preference route search showed reflection of traffic route search disposition for the driver individual. This paper has five important meaning. (1)The approach is similar to the driver's route selection decision process. (2)The approach is able to control of route appraisal criteria for the multiple attribute. (3)The approach makes subjective judgement objective by a non additive. (4)The approach shows dynamic route search for the alternative route search. (5)The approach is able to consider characteristics of individual drivers attributed for the preference route search.

Objectives: The aims of this study were to review the standards and key components of the standards for disposable masks in Korea, the US, EU, Japan, and China and to evaluate the appropriateness of disposable masks during a virus pandemic. Methods: We reviewed the standards in the above countries and compared their key elements for each standard. For the second purpose, systemic paper gathering using key words like 'mask', 'respirator' 'virus', and 'coronavirus' in the PubMed search engine was performed. Fifty-three papers were selected and reviewed in regard to the appropriateness of test protocols with sodium chloride(NaCl) particles for virus filtration and the effectiveness against viruses. Results: The standards for masks are largely divided into two categories: US standards and EU standards. In Korea, the Ministry of Employment and Labor adapted the EU standards for workers and the Health Masks adopted the Ministry of Employment and Labor standards by the Ministry of Food and Drug Safety. Regarding airborne viral infections, WHO emphasizes only droplet infection, while many studies have shown that small particles enter the air through coughing or sneezing, which increases the possibility of airborne infection. Compared to other particles, various factors such as airborne viability and the ability to replicate the virus in the body are further involved in the virus's airborne infection rate. Airborne infection is classified into absolute air infection, preferential air infection, and opportunistic air infection. The NaCl-certified N95 mask showed good filtration efficiency against viruses and NaCl particles were proved to be a surrogate material for viruses. From this, KF94 is also expected to be effective in blocking viruses. Conclusion: The N95 test method could be used as a surrogate test method for virus filtration. N95-class masks have been found to effectively block viral infections in the air. However, surgical or medical masks are only partially effective against airborne virus infection though they could effectively block large droplet infection. However, most studies considered in this study targeted N95 in foreign countries and studies on masks actually used in Korea are very limited, so studies on microorganisms and reuse on domestic masks should be conducted in the future.
