대부분의 주거정비사업관련 연구를 보면 사업추진에 미치는 영향변수를 규명하기 위하여 추진시점을 정하고 있으나 서로 다르게 정하고 있으며, 또한 이에 따른 변수값의 변화정도를 제시하지 않고 있으므로 본 연구에서는 추진시점의 차이가 사업입지변수에 어떤 영향을 보여주는가를 규명하기 위하여 서로 다른 추진시점을 정하고 해당 변수값의 변화정도를 관찰하였다. 사업의 추진단계는 구역지정, 추진위승인, 조합설립인가, 사업시행인가 등 4개의 단계로 구분하고 판별분석, 상관분석 등의 분석도구를 이용하여 그 차이를 규명하였다. 분석결과 재개발사업의 경우 사업시행인가단계를 제외한 3개의 추진단계는 동질의 집단으로 해석할 수 있었으나 사업시행인가단계는 타 단계와 서로 다른 경향을 보여주고 있어 동질집단으로 해석할 수 없었다. 반면, 재건축사업의 경우 4개 집단 모두 같은 경향을 보여주고 있어 동질집단으로 해석되나 구역지정단계의 판별분석결과값은 유의성이 낮게 나타나는 단점을 갖고 있다. 따라서 주거정비사업의 사업추진정도를 파악하는데 필요한 사업추진단계의 차이는 대부분 유사한 결과값으로 관찰되었으므로 사업추진단계에서 서로 다른 단계를 기준으로 분석하여도 같은 결과 값을 보여줄 것으로 사료된다.

미국 오하이오주 씬씨내티 대도시지역을 연구지역으로 하여 소규모 기업의 입지 및 연계 그리고 당면 문제점을 구명하였다. 현 입지의 유리성은 제품의 판매 용이가 가장 중요하게 나타나고 있으며 다음으로 고속도로와의 근접성이 중요한 입지조건이며 이들 기업의 물자의 공간연계는 아주 탄력적인 거리 조락 현상을 나타내고 있다. 지역별 물자의 공간연계를 보면 압도적 다수가 역내에서 공급되고 판매되어 소기업이 물자의 전방연계와 후방연계가 높고 지역경제에의 발전기여도가 높다는 기존의 주장들과 일치된다. 입지적 문제점 조사 결과는 전체적으로 불리한 입지조건이 없다는 응답이 가장 많았으나, 노동력 부족, 과다한 세금, 인접지역의 노후화, 용지부족이 현재 입지에서 불리한 것으로 조사되었다. 현재 소규모 기업이 당면하고 있는 가장 큰 문제는 양질의 노동력 확보가 어렵다는 것이며, 다음으로 제품 판매, 자금, 기술, 시설, 장비의 순으로 어려옴을 겪고 있는 것으로 나타났다. 비록 외부조직과 자문하겠다는 기업이 많지 않으나 이들이 역내 자문조직을 선호하는 것으로 드러났다. 이를 통해 볼 때 양질의 노동력 배출이 우선 과제이며 소규모 기업에 대한 판로개척과 자금지원, 기술 상담 등이 주된 육성방향이라고 본다. 이를 위해 역내 소규모 기업들간의 긴밀한 네트워크가 형성될 필요가 있으며 이들을 지원하는 연구소, 기업 협동조합, 대학간의 상호 협력적인 네트워크 체계를 구축할 필요가 있다.

In the context of sustainability which is understood as equilibrium among three elements; human, space and time, the imbalance within the Seoul metropolitan area hinders its own area or the nation from development. Claims for the balanced development in the area are set up on the premise that there is a locational order of priority among the zones named 'overpopulation suppression', 'growth management' and 'conservation'. Based on the systematic consideration of competitiveness this study adopts the premise as a research hypothesis. Factor scales derived from the factor analysis, a kind of multivariate dependence analysis play an important role in this research process since they are measured by interval-ratio level and can be used for dependent variables in the statistical analysis. The hypothesis test carried out by means of the analysis of variance(ANOVA) concludes that the hypothesis assuming no difference in the competitiveness is rejected but the alternative hypothesis of the locational order mentioned above should be adjusted. Eigenvalues derived from the factor analysis could be used as weights for aggregate factor scales and the scales show that the priority is in the order of growth management - overpopulation suppression - conservation zones. This finding has also a significant implication that the countermeasures to cope with the lowering of the competitiveness resulted from the continuous and absolute restraints should be provided. And strategic approaches which are composed of key factors for each zone are deducted from in-depth review. (1) overpopulation suppression zone; health-welfare, educational base, public service factors, focusing on health-welfare one, (2) growth management zone; public service factor and (3) conservation zone; health-welfare, educational base factors, also focusing on health-welfare one.

In new deregulated electricity market, short-term price forecasting is key information for all market players. A better forecast of market-clearing price (MCP) helps market participants to strategically set up their bidding strategies for energy markets in the short-term. This paper presents a new prediction strategy to improve the need for more accurate short-term price forecasting tool at spot market using an artificial neural networks (ANNs). To build the forecasting ANN model, a three-layered feedforward neural network trained by the improved Levenberg-marquardt (LM) algorithm is used to forecast the locational marginal prices (LMPs). To accurately predict LMPs, actual power generation and load are considered as the input sets, and then the difference is used to predict price differences in the spot market. The proposed ANN model generalizes the relationship between the LMP in each area and the unconstrained MCP during the same period of time. The LMP calculation is iterated so that the capacity between the areas is maximized and the mechanism itself helps to relieve grid congestion. The addition of flow between the areas gives the LMPs a new equilibrium point, which is balanced when taking the transfer capacity into account, LMP forecasting is then possible. The proposed forecasting strategy is tested on the spot market of the Nord Pool. The validity, the efficiency, and effectiveness of the proposed approach are shown by comparing with time-series models

It is expected that there will be delay of scheduled transmission network reinforcement and huge investment of renewable energy resources in Korea. As transmission capacity expansion delayed, supplying power to Seoul metropolitan area will not be increased as scheduled. In addition, uncertain renewable energy out of Seoul metropolitan area can cause transmission congestion in the future power system. These two combining effects will make the difference in locational marginal prices(LMP) and congestion costs increase. In that sense, this paper will analyze how much the congestion costs for Korea power system are incurred in the future power system. Most of previous approaches to analyze the congestion costs for electric power system are based on the optimal power flow model which cannot deal with hourly variation of power system. However, this study attempted to perform the analysis using market simulation model(M-Core) which has the capability of analyzing the hourly power generation cost and power transmission capacity, and market prices by region. As a result, we can estimate the congestion costs of future power system considering the uncertainty of renewable energy and transmission capacity.

In this paper the prevailing geography of the information sector, fousing on its occupatonal dimension, is examined. The purposes of this paper are to analyze the labor force share of information occupation workers at each special city and region, to compare the inter-regional distribution of information workforce and to analyze regional share of information occupations in manufacturing industry. Spatial pattern of size and occupational composition of information sector shows a core-periphery disparity. There is a clear evidence of Seoul's dominance of the information economy, particularly such as scientific and technical, consultative services, management and process control function. Also the distribution of information workers in manufacturing industry over space was polarized than is the case for total manufacturing employment and noninformation workers. Therefore Korean information economy is marked by a highly articulated spatial division of labor within individual industry, which can be attributed to the locational characteristics of information intensive industries and industrial composition of regional economy. From the results of this study, information employment prospects among regions of Korea would reinforce the unequal geography of job opportunity. In this light, regional policy efforts should be given to the improvement of information infrastructure to facilitate new computer-based service products and process in peripheral regions.

The philosophers think that the increase of loneliness in technological society is caused by the reduced feeling to some extent. They started to think the integral feeling in terms of existentialism away from Visualcentrism. It is apparent that in architectural design a concrete feeling(sense) out of Visualcentrism of modern architecture is reflected in a architecture. In particular, the architects such as Herzog & de Meuron, Steven Holl, Peter Zumthor, Kuma Kengo think that the existential value of the objects is important and would like to reflect the existence of materials on architecture. This study is to analyze the common points and different points regarding how in these works sensible experiences are approached. The results show that these works have common features containing escape from visual formativeness in the space, pursuit of locational connection, study on pure essence of the materials, and reflectance of the feeling of depth and motility. In addition, the actual beings of the materials for this feeling were mainly used and showed some difference in terms of the usage of local materials, natural environment, five senses of body. This study is important in the point of view that there are few researches that compared with the characteristics of architects' works while there were many researched that treated architecture as sensible view.

A biological assessments of fish community structure were carried out in the lower reach of Seomjin River from May 2009 to November 2010. The collected fish from the six surveyed sites were 63 species belonging to 24 families, and 10 orders. Although species was different depending on sites, the numbers of individuals were not shown significance on sites. Locational dominant species were different. For example, the dominant species on May were Zacco platypus at W-1, Zacco temminckii at W-2, Acanthogobius flavimanus at W-3 and W-4, and Leiognathus nuchalis at W-5 and W-6. There is no seasonal differences in species. Species diversity was the best up to 2.64 on May at W-1 from 1.33 on November at W-6. As a result of an analysis about environmental factors for the numbers of fish species and individuals in each surveyed sites, the most effective groups were DO, BOD, and COD. The proportional difference was high on May than November between transient and asymptotic projections for population size and population growth rate for simulations starting at the current or theoretical stage distribution.
