  • This study uses expert analysis as a method of research to identify the value of hanok in rural landscapes. To do so, the study conducted the Delphi method and the AHP survey twice. First, the Delphi method was used on experts who have either studied rural landscape, regional development, hanok or have adequate knowledge in such areas, concerning the definiton of sustainable rural landscapes, the role of hanok in rural landscapes, the problems rural hanoks face, and the preservation and utilzation of rural hanok. Based on this, the AHP survey was conducted. The survey results showed that sustainable rural landscapes are 'landscapes in which the transformation proces coexists from traditonal to modern times.' The role of the rural hanok was shown to be 'the forming of landscapes that expres the historical flow of the vilage.' In the subsequent survey of rural landscapes, the order of import limitationance of hanok was regionality, historicity, harmoniousnes, eco-friendlines and familarity. However, a may be that this study is based on expert opinion which may not be regarded as universal. Therefore, future research on the basis of this study wil have to be conducted in a way to identify the value of hanok in rural landscapes from the perspective of various groups.

  • Background: Guideline for practice is useful because it can be the standard for assessment and way to improve quality. We need to take account of expert opinion and consensus as well as scientific evidences to develope practice guideline because it should be practical. Delphi method has been developed to gather opinions from experts fairly. This study was designed to develop practice guideline and apply it to practices as a method to improve quality in primary medical care. Methods: Hypertension(in adults over 18 years old) was selected as a target problem. Self questionnaires about management of hypertensive patients were developed by a researcher with advice of 11 experts. The questionnaires were designed to response as a 5 pont scale. The results of previous questionary were given to respondents in second and third questionnaires. If needed, the questionnaires were changed on the previous responses. The items with medium greater than or equal to 4 point in 1st and 2nd responses were accepted in guideline. The items with medium lesser than or equal to 3 point were questioned again about whether they can be excluded or not. The criteria for assessment was made with reference to guideline and applied to 85 hypertensive patients of 9 family practitioners. At 3 months after practice guideline had been given to family practitioners, performance of same practitioners was assessed with 36 new hypertensive patients. Results: 23 professors in family medicine, 22 family practitioners and 6 cardiologists, responded among 50, 50, 15 respectively. Practice guideline with 33 items was developed as a result of 3 times questionaires. The difference of responses between professors in family medicine, family practitioners and cardiologists was not significant. Performance of practice was improved in diagnosis, history taking about 6 fields, laboratory examination and decision making about time of pharmaceutical prescription. It was not improved in physical examination, life style modification, method of pharmaceutical prescription, choice of initial antihypertensives and history taking about duration of disease and diet habit. It was decreased in history taking about psychosocial factors. The assessment scores were low in history taking, physical examination and life style modification before and after use of practice guideline. Conclusion: Practice guideline for hypertension could be developed by Delphi method. Performance of practice improved partially after use of guideline.

  • Globally, cancer research has been considered one of the most important field of biomedical researches. Recently, in Korea, there are increasing concerns about cancer research and the development of national cancer control programme. For the efficient investment in cancer research at the national level, strategic approach is needed based on the nationwide information about current status of research. However even the basic data on cancer research have not been systematically collected, and are not available when necessary. The aim of this study is to assess current status of cancer research. For this purpose, this study applied two round Delphi method in which fifteen experts in cancer research fields participated. They rated each items on the initial list at the first round, and modified their responses at the second round. Panels responded that pathogenesis of cancer, research & development of cancer drug, and oncogene, etc. are the most urgent and important research Holds. They assessed national level of cancer research as being 49.6% of the world highest level. Coefficient of variation tended to be lowered with the iteration. Predictive stability was evaluated to be lower in items of urgency than in items of importance and research level. Although this study shares the same limitations in the selection of the experts with many other Delphi studies, it provides a primary data that would be required to plan the national strategy of the cancer research.

  • In the stock marketing. investor needs speedy and accurate decision making for the investment. A stock exchange index provides the important index of the early of 1993 in Korea using Fuzzy Delphi Method(F. D. M) which is widely used to a mid and long range forecasting in decision making problem. In the Fuzzy Delphi method, considerably qualified experts an first requested to give their opinion seperately and without intercommunication. The forecasting data of experts consist of Triangular Fuzzy Number (T.F.N) which represents the pessimistic, moderate, and optimistic forecast of a stock exchange index. A statistical analysis and dissemblance index are then made of these subject data. These new information are then transmitted to the experts once again, and the process of reestimation is continued until the process converges to a reasonable stable forecast of stock exchange index. The goal of this research is to forecast the stock exchange index using F.D.M. in which subjective data of experts are transformed into quasi -objective data index by some statistical analysis and fuzzy operations. (a) A long range forecasting problem must be considered as an uncertain but not random problem. The direct use of fuzzy numbers and fuzzy methods seems to be more compatible and well suited. (b) The experts use their individual competency and subjectivity and this is the very reason why we propose the use of fuzzy concepts. (c) If you ask an expert the following question: Consider the forecasting of the price index of stocks in the near future. This experts wi11 certainly be more comfortable giving an answer to this question using three types of values: the maximum value, the proper value, and the minimum value rather than an answer in terms of the probability.

  • BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.
