The purpose of this study is to develop the diagnostic indices system that can be applied to the evaluation of rural village level, because the indicators developed in many existing studies were mostly consisted of statistical data in higher level than rural villages as well as those were difficult to apply to rural village level empirically. In order to develop the empirical diagnostic indices system, which has 52 indices with 7 categories, this study not only classified the kind of rural village facility and the regional development project of government, but also surveyed the specialist opinion with Delphi method. Especially, this study standardized the all diagnostic indices with positive value to remove the indices with negative values. Finally, the results that the study applied the empirical diagnostic indices to the 15 sample villages of Jinan-gun and Cheongyang-gun showed that there was the applicability of the indices system in the village level.

The main contribution of this research is that it gives:(1) a rational criterion to select the best self-localizing method for a particular situation, and (2) an appropriate arrangement of the landmarks to minimize the error. In this paper, the authors propose a set of indices to evaluate the accuracy of the self-localizing methods, and the indices are derived from a sensitivity which is defined as the ratio of the localizing error to sensor error. And then, we compare the accuracy of self-localizing a mobile robot with landmarks based on the indices, and propose a rational way to minimize the localizing error.

본 연구에서는 국내외 산불위험지수들의 국내 적용성에 대해 평가하였다. 이를 위해, 먼저, 전 세계적으로 많이 사용되는 산불위험지수들을 소개하고 그 계산 과정을 비교하였다. 이후 실제 국내 산불 발생 건수의 경년 변동 및 계절적 변동 경향을 각 산불위험지수의 적용 결과와 비교하였다. 마지막으로, 향후 국내에 적용 가능한 지수들을 선정하고 그 적용성을 높일 수 있는 보완 방향을 제시하였다. 고려한 산불위험지수는 미국에서 개발된 MI, KBDI, FFWI, mFFWI, 러시아에서 개발된 NI, ZhI, MNI, 그리고 국내에서 개발된 DWI 등이다. 본 연구의 대상지역으로 동해안 지역을 선정하였으며, 산불 발생 건수는 산림청에서 제공하는 산림통계연보를 참고하였다. 연구결과 대부분의 산불위험지수는 경년변동 정도가 크지 않아 실제 산불 발생 건수를 잘 나타내지는 못하는 것으로 나타났다. 그러나 대부분의 산불위험지수가 월 변동은 잘 나타내는 것으로 나타났다. 산불위험지수와 실제 산불 발생 건수의 상관분석 결과 최종적으로 동해안 지역에 적합한 지수로 mFFWI, MI, ZhI, DWI 등을 선정하였다. 그러나 이들 지수는 현재 상태로 국내 산불 발생을 적절히 나타낸다고 판단하기는 어려우며 추가의 보완이 필요한 것으로 판단되었다. 지수별로 보완되어야 할 부분도 각각 다르며, 따라서 이들에 대한 평가도 보완이 수행된 이후에야 가능할 것으로 보인다.

본 연구는 지역재난관리체계의 평가지표개발을 위해 인위재난의 계층구조 및 지표를 설정하고 각 계층구조별 평가지표간 가중치 및 우선순위를 결정하였다. 측정 결과 예방영역의 상대적 중요도가 가장 높게 평가되었다. 또한, 대응영역이 예방영역 다음으로 높게 평가되었다. 그 이유는 인위재난은 재난발생이 곧 피해발생으로 이어지기 때문에 피해자 구조나 탐색을 강조하게 되어 대응의 중요성이 강조된 것으로 판단된다.

There are two ways to mitigate the drought. One is the structural measures such as storage of irrigation water, development of emergency wells, etc. The other one is the nonstructural measures such as water saving management by the early warning system. To precast and evaluate the drought, we need to develop the drought indices for agriculture. In the present drought preparedness plans of Ministry of Agriculture and Forestry (MAF), it is prescribed that the preparedness levels should be classified by considering the precipitation, reservoir storage, soil moisture in paddy and upland, and the growing status of crops. However there are not clear quantitative criteria for consistent judgment. This shows that we have not selected and utilized the proper drought index for agriculture and we did not have the information system to calculate the drought indices periodically and warn the outbreak of the drought. The objectives of the study are to develope of Agricultural Drought Evaluation System and to evaluate this indices for current agricultural status using the system.

Ample research effort has been oriented into developing damage indices with the aim of estimating in a reasonable manner the consequences, in terms of structural damage and deterioration, of severe plastic cycling. Although several studies have been devoted to calibrate damage indices for steel and reinforced concrete members; currently, there is a challenge to study and calibrate the use of such indices for the practical evaluation of complex structures. The aim of this paper is to introduce an energy-based damage index for multi-degree-of-freedom steel buildings that accounts explicitly for the effects of cumulative plastic deformation demands. The model has been developed by complementing the results obtained from experimental testing of steel members with those derived from analytical studies regarding the distribution of plastic demands on several steel frames designed according to the Mexico City Building Code. It is concluded that the approach discussed herein is a promising tool for practical structural evaluation of framed structures subjected to large energy demands.

The purpose of this study is to develop indices and a scoring method for effectively evaluating the project of rural well-longevity villages which makes up for insufficient parts of existing projects on improving settlement foundation and production environment. Evaluating indices include qualitative factors originated from the characteristics of the project so a scoring method based on an information measure technique is used for evaluating the results from each village. Evaluating indices are provided differently depending on each purpose for evaluation. Result indices can be used for ranking project villages and fundamental indices can be used to analyze villages elaborately to improve project plans.

To evaluate iron nutritional status and to compare biochemical indices used for evaluation of iron nutriture, fasting blood sample was taken from 96 Korean female college student and hemoglobin(Hb) concentration, hematocrit(Hct), serum iron, total iron binding capacity(TIBC) and serum ferritin concentration were measured and transferrin(TF) saturation was calculated. Prevalence of iron deficiency varied from 4.2% when judged from Hb concentration and Hct to 38.5% and 40.6% when TIBC and serum ferritin concentration were used. TIBC was negatively correlated with serum ferritin(r=0.4561, p<0.001), while other indices showed positive but less significant correlations(p<0.05). Regarding iron status judged by serum ferritin was regarded as true iron status, the present cutoff points of Hb, Hct, serum iron, TF saturation were very insensitive in identifying the subjects with iron deficiency. Only TIBC was suitable for detecting iron deficiency in the study subjects. It is concluded from the study results that iron deficiency in young Korean adult women would be significantly underestimated with presently used biochemical measurements except TIBC and new cutoff points of these indices were proposed based on sensitivity, specificity measured prevalence, and positive and negative predictive values.

In this study, a structural health monitoring system for cable-stayed bridges is developed. In the system, condition assessment of the structure is performed based on measured records from seismic accelerometers. Response indices are defined to monitor structural safety and serviceability and derived from the measured acceleration data. The derivation process of the indices is structured to follow the transformation from the raw data to the outcome. The process includes noise filtering, baseline correction, numerical integration, and calculation of relative differences. The system is packed as a condition assessment program, which consists of four major processes of the structural health evaluation: (i) format conversion of the raw data, (ii) noise filtering, (iii) generation of response indices, and (iv) condition evaluation. An example set of limit states is presented to evaluate the structural condition of the test-bed and cable-stayed bridge.

Technology Management and Research & Development(R&D) have been one of the most difficult divisions for measurement and evaluation. In spite of these difficulties, the importance of R&D has been dramatically increased. It is very difficult to manage more efficiently and effectively than any other departments of production, finance, marketing and so on. As criticizing the shortcomings of the traditional evaluation system in making decisions for corporate management which has only been focused on financial indices, so Kaplan & Norton has suggested the Balanced Scorecard(BSC) which can be managed Critical Success Factors(CSF) in accordance with corporate's strategy. The Analytic Network Process(ANP), based on the Analytic Hierarchy Process, allows the decision makers to leap beyond the traditional hierarchy to the interdependent environment of network modeling. Based on BSC, this study has developed the evaluation system for R&D which has used ANP transforming quantitative and qualitative indices to the quantifying scales in evaluating R&D.
