This paper proposes the ESFVQ(energy subspace fuzzy vector quantization) that employs energy subspaces to reduce the quantizing distortion which is less than that of a fuzzy vector quatization. The ESFVQ is applied to a speaker adaptation method by which Korean words spoken by unknown speakers are recognized. By generating mapped codebooks with fuzzy histogram according to each energy subspace in the training procedure and by decoding a spoken word through the ESFVQ in the recognition proecedure, we attempt to improve the recognition rate. The performance of the ESFVQ is evaluated by measuring the quantizing distortion and the speaker adaptive recognition rate for DDD telephone area names uttered by 2 males and 1 female. The quatizing distortion of the ESFVQ is reduced by 22% than that of a vector quantization and by 5% than that of a fuzzy vector quantization, and the speaker adaptive recognition rate of the ESFVQ is increased by 26% than that without a speaker adaptation and by 11% than that of a vector quantization.

The purpose of this paper was to understand the outlines of 1) common and free curricula implemented by the first pilot schools and 2) Home Economics related programs from both curricula. This study analyzed the 42 reports from the first pilot schools which implemented the free learning semester in 2013. The results showed that more than half of schools set two or more emphasis models of the free learning semester. In 15 out of 28 schools, the lesson hours of Home Economics were reduced by one to three hours. Various common curricula were implemented in many aspects of teaching-learning methods, curriculum, evaluation, and subject related career lessons. Free curriculum was implemented in four areas such as career exploration, student optional program, club activity, and art sports activity. In common curriculum, Home Economics was carried out in 17 out of 39 schools. The Home Economics class included subject related career lessons and improvement of teaching- learning methods. Various interesting activities and programs as a free curriculum were implemented in career exploration, students' optional program, and club activities in 38 schools. The most frequently implemented was the activity program related to food and nutrition. Further research was proposed to develop students' optional programs related to Home Economics subject, responding to their needs.

Recently one of interest concern in domestic housing market is to reduce the difference of supply and demand. Exact demand estimation by accurate demand region is a essential cue to reduce the gap. This empirical study compared the data of housing subscriber's real address with estimated demand area on household movement, which are applied by advanced studies. This empirical case data is related to 3 housing development districts in metropolitan area. As a result, This study found that the real demand area has a more widened coverage compared with those of household movement one. For to establish exact demand area, we found, more complementary considerations should be taken. Especially some factors such as distance between a project site and downtown of Seoul Metropolitan City, locational competitiveness on main demand and behind demand, and development scale are more considerable variables. In additionally, we found the demand areas are influenced by housing rental types, sizes and the real estate business trends. And also, this study found those factors should be considered with housing price and locational competitiveness.

Nowadays, it is possible to construct the DEMs of urban area effectively and economically by LiDAR system. But the data from LiDAR system has form of DSM which is included various objects as trees and buildings. So the preprocess is necessary to extract the DEMs from LiDAR DSMs for particular purpose as effects analysis of man-made objects for flood prediction. As this study is for extracting DEM from LiDAR DSM of urban area, we detected the edges of various objects using edge detecting algorithm of image process. And, we tried mean value filtering, median value filtering and minimum value filtering or detected edges instead of interpolation method which is used in the previous study and could be modified the source data. it could minimize the modification of source data, and the extracting process of DEMs from DSMs could be simplified and automated.

This paper examines the evolution of the systems of innovation approach and its main issues. At first, national systems of innovation have appeared on the purpose to substitute the neoclassical macroeconomic policies. But various criticisms have been raised because of the restriction within national boundary of analysis, the lack of dynamic analysis, the danger of institutional determination, the deficiency of theoretical accuracy in national systems of innovation. Technological systems, regional systems of innovation, sectoral systems of innovation have been developed to overcome criticisms about national systems of innovation. Nevertheless the unsettled questions in the systems of innovation approach remain. The academic and policy-making usefulness of the systems of innovation approach will be expanded by development of the complementary researches within approach.

팔머가뭄지수(Palmer Drought Severity Index, PDSI)는 가뭄을 정량적으로 표현하기 위해 제안된 최초의 포괄적인 가뭄지수라 할 수 있다. 가뭄을 단순히 하나의 기상인자로만 판단하려 한 것이 아니라 수문순환 과정 속에서 여러 가지 요소들의 복합적인 작용에 의한 결과로 인식하고 이를 가뭄지수 산정 과정에 고려하고자 하였다. 따라서 PDSI는 가뭄뿐만 아니라 습윤상황을 모니터링 하기 위한 용도로 이용될 수 있으며, 수분수지 분석을 통해 얻을 수 있는 함양량, 유출량, 토양수분량의 정보는 그 자체로서도 분석 대상 지역의 수분상황과 관련된 중요한 정보라 할 수 있다. 이러한 점에서 PDSI는 방법론상의 여러 가지 한계에도 불구하고 지금까지 가뭄의 모니터링 및 관리를 위해 우리나라를 비롯한 여러 국가 및 지역에서 널리 이용되고 있으며, 가뭄 정량화를 위한 새로운 가뭄지수 개발 시 적합성의 비교 기준으로 고려되고 있다. 그러나 지금까지 우리나라에서는 PDSI에서 고려하고 있는 기상 및 수문학적 조건이 우리나라의 상황을 적절히 표현할 수 있는가에 대한 검토가 미흡한 상황이라 할 수 있다. 우리나라의 자료를 이용하여 PDSI를 산정하였다 할지라도 지수 산정 과정에서 고려하고 있는 기상 및 수문특성이 적절하지 않을 경우 산정된 PDSI가 나타내는 가뭄상황과 실제 우리나라의 가뭄상황은 다를 수 있다. 특히 PDSI 산정 과정에서 잠재증발산량 산정 방법으로 이용하고 있는 월열지수법은 방법의 한계로 인해 우리나라와 같이 동절기 평균기온이 0도 이하로 떨어지는 경우에는 증발산량이 발생하지 않는 것으로 고려하고 있다. 이는 우리나라의 실제 증발산 발생 양상과 비교할 경우 크게 차이가 나는 점이라 할 수 있으며, 강수량과 증발산량의 관계에 대한 검토로부터 지수 산정 과정이 시작되는 PDSI에 있어 이러한 오차는 결과의 신뢰성 확보에 많은 어려움을 초래할 수 있다. 따라서 본 연구에서는 기존 PDSI에서 이용하고 있는 월열지수법을 대체할 수 있는 방법에 대해 검토하였으며, 잠재증발산량 산정 방법의 변경에 따라 산정된 PDSI의 변동 양상에 대해 분석하였다. 본 연구의 결과를 통해 가뭄 모니터링 및 관리를 위한 지표로 널리 이용되고 있는 PDSI의 활용에 있어 유용한 정보 제공이 가능할 것으로 판단된다.

The industrial development of Goryeong County was started by the operation of the Ssangrym Agro￢industrial complex in the 1980s. As of 2m3, there are 6 industrial complexes in Goryeong County which account for 80 percent of total employment and 67 percent of total production outPuts in local manufacturing. The local manufacturing industries grew steadily before the 1997 financial crisis which resulted in industrial decline and have shown again a growing tendency since 2000. In this period of growth, manufacturing outPuts are increased and the industrial structure are improved, while employment and value added are in stagnation. The major industrial agglomerations are based in Gaejin-Myun, Dasan-Myun and Ssangrym-Myun, all of which are those in which the agro-industrial complex is operated. More than half of local manufacturing finns are those which came to move in from other regions, looking for cheap labour forces, agglomeration of the related finns and the easy accessibility to transport and communication. However, such local advantages are increasingly losing due to the shortage of labour forces and the lack of industrial networks. Some policy agendas can be suggested as follows. First of all, industrial policy should attempt links with the building-up of the Daegu Technopolis and the up-grading of the local industrial structure towards the knowledge-based industries. Secondly, the local government should make efforts to establish the innovation supporting system for local firms and the industrial and residential basis.

A water resource plan is routinely based on a natural flow and can be estimated using observed streamflow data or a long-term continuous rainfall-runoff model. However, the watershed with the natural flow is very limited to the upstream area of the dam. In particular, for the ungauged watershed, a rainfall-runoff model is established for the gauged watershed, and the model is then applied to the ungauged watershed by transferring the associated parameters. In this study, the GR4J rainfall-runoff model is mainly used to regionalize the parameters that are estimated from the 14 dam watershed via an optimization process. In terms of optimizing the parameters, the Bayesian approach was applied to consider the uncertainty of parameters quantitatively, and a number of parameter samples obtained from the posterior distribution were used for the regionalization. Here, the relationship between the estimated parameters and the topographical factors was first identified, and the dependencies between them are effectively modeled by a Copula function approach to obtain the regionalized parameters. The predicted streamflow with the use of regionalized parameters showed a good agreement with that of the observed with a correlation of about 0.8. It was found that the proposed regionalized framework is able to effectively simulate streamflow for the ungauged watersheds by the use of the regionalized parameters, along with the associated uncertainty, informed by the basin characteristics.

오늘날 ICT는 타산업과의 융합을 통한 경제성장의 핵심수단 및 사회이슈를 해결할 도구로서 인식되고 있으나, 우리나라의 R&D 성과활용은 기술개발의 성공률에 비해 매우 낮은 수준이다. 이는 R&D의 공급자인 연구자 중심의 기획, 기술개발 추진이 주된 원인으로 지적되고 있다. 이에 따라, 수요자의 요구에 부합되는 시장성 있는 제품 서비스 구현이 R&D 추진의 중요한 요소로 대두되고 있으며, 기획에서부터 실사용자의 요구사항을 도출하고 기술개발과정에서 지속적으로 사용자의 피드백을 통해 수정해 나가는 리빙랩 방식의 적용이 절실히 필요한 상황이다. 그러나, 그동안 리빙랩 R&D는 사회문제해결형 또는 지역환경개선형에 집중해서 추진되어 왔다. 본 논문에서는 중소기업 R&D사업에의 리빙랩 도입 방안에 대해 검토해보고 이를 통해 기술개발 결과물의 사업화 가능성을 향상시키기 위한 효율적인 R&D 추진방안에 대해 제안하고자 한다.
