Our country has made every efforts to develop Real Estate Transaction culture with emphasis on Licensed Realtors by introducing Real Estate Transaction Law in 1983. Also, MOLIT(Ministry of Land, Infrastructure and Transport) designated several organizations including KAR(Korea Association of Realtors) as Real Estate Transaction Information Network Licensees for data credibility enhancement and transaction transparency. Nevertheless, the level of law abiding spirit and transaction culture are still similar to those of the old 'Bokdeokbang' era. The under-developed transaction behaviors prevent the social capital of people's credibility on Licensed Realtors from advancing, and results in the outcomes of unnecessary social cost. That is, very low credibility on the data on Sales Items in the market and the fear of speculative real estate price uprise and market distortions are continuing on. In this context, the purpose of this study is to propose the model of GIS-based Modernized Real Estate Transaction System and its execution policies to support credible Real Estate Information to the general public for efficient transactions in the market. Accordingly, the study aims at contributing to the modernization of Real Estate Transactions, fostering competitiveness of Realtors in the Real Estate Market.

As the prevalence of cloud computing increases, various cloud service types have emerged, such as IaaS, PaaS, and SaaS. The growth and diversification of these cloud services has also resulted in the development of technology for cloud service brokers (CSBs), which serve as intermediate cloud services that can assist cloud tenants (users) in deploying services that fit their requirements. In order to broker cloud services, CSBs require the specification of structural models in order to facilitate the analysis and search for cloud services. In this study, we propose a variability-based service analysis model (SAM) that can be used to describe various cloud services. This model is based on the concept of variability in the software product line and represents the commonality and variability of cloud services by binding variants to each variation point that exists in the specification, quality, and pricing of the services. We also propose a virtual cloud bank architecture as a CSB that serves as an intermediate to provides tenants with appropriate cloud services based on the SAM.

This study is a study on the requirements, resources, and role of policy broker in the policy process. Particular attention was paid to two requirements of legitimacy (official authority, political support) and professionalism (information and expertise, skilled leadership) as the requirements of policy broker. This study analyzed the process of transforming the actor conflicts surrounding the media rep legislative process into a cooperative relationship by being mediated by a strong influential policy broker. Policy brokers can mediate opinions among participating actors and play a role in coordinating conflicting interests. In the mediarep policy process, the policy brokers were unable to resolve conflicts due to lack of legitimacy and expertise in the first phase (legislative grace period) and the second phase (legislative loophole). However, the legitimacy of the six subcommittees of the National Assembly (the legislative period) and the expertise of the Korea Communications Commission were able to succeed in policy-making by acting as a successful policy brokers through complementary activities.

This study aims to survey the influence of the internet-based real estate transaction systems used by the common people on their decision-making for buying the real estate. That is, the purpose of this study is to review how the system for selection of the real estate has influence on the decision-making for buying the real estate, by exerting influence on the customer-satisfaction. Also, I want to present a scheme for the more effective internet-based real estate transaction system so that the real estate agents may grasp the on-line real estate transaction system and understand the intention of the customers for buying, and thereby establish the active marketing strategy.

The most widely used information searching method in the current internet environment is the keyword-based one, which has certain limitations in terms of precision and recall. Most major internet portals provide directory-based searching as a means to complement these limitations. However, that they adopt different classification schemes brings significant inconvenience to the users, and it consequently suggests a need to develop mapping gateway to provide cross-portal, or cross-directory information searching. In this context, this study attempts to develop a prototype system of intermediary gateway for integrated search, using the directory services of three major portals, Naver, Yahoo and Empas, and test its performance.

개방형 혁신(Open Innovation)은 조직 내부에 국한되어 있던 기술개발 활동을 기업 외부까지 확장하여 외부 기술지식과 내부 기술력을 함께 활용하는 혁신성과 극대화 전략을 의미한다. 개방형 혁신은 기술개발의 성공률이 높고, 비용이 상대적으로 저렴하다는 장점을 갖고 있어 이에 근거한 기술중개서비스 전문기업들이 글로벌시장에서 활동하고 있다. 그 대표적인 사례가 나인시그마(NineSigma) 및 이노센티브(InnoCentive)이다. 그러나, 그러나 현재까지 이들 기업은 매출액 및 R&D 투자가 일정규모 이상인 글로벌 대기업을 대상으로 하고 있으며, 중소기업을 수혜자로 한 개방형 혁신 서비스는 충분히 제공되고 있지 않다. 본 연구에서는 부품 소재 중소기업을 주요 수요자로 한 개방형 혁신 기술중개서비스 모델을 제안하고 있다. 국내 부품 소재산업의 경쟁력 제고의 핵심 관건은 부품소재 중소기업의 기술혁신 역량 강화로 볼 수 있다. 본 연구에서는 개방형 혁신의 장점을 부품소재 중소기업에서 활용하기 위한 필요조건을 조사하고, 그에 근거하여 개방형 혁신 중개서비스 모델에 포함된 다양한 혁신주체들의 역할을 제안하였다. 본 연구의 세부 내용을 구조화하여 제시하면 다음과 같다. (1) 개방형 기술혁신체제의 정의와 동향 검토 (2) 국내외 개방형 기술혁신의 사례 조사 (3) 부품 소재기업 대상의 개방형 기술혁신체제 도입 필요성 타당성 검토 (4) 부품 소재산업 개방형 기술혁신 모델 개발 (5) 국내 부품 소재산업 발전을 위한 개방형 기술혁신 활성화 정책과제 검토

UDDI server is the web services registry enabling users to register and search for web services. However, the existing UDDI servers do not provide any information about web services qualify. We designed and developed a UDDI broker system which actively monitors and analyses the qualify of web services. The analysis results are presented to users in statistical figures and graphs. With this information a user can select a web service that meets his/her needs. Availability, performance, and stability were the metrics used for the service qualify measurement and analysis.

A series of coffee middlemen has come to be regarded as an exploitative force in the lives of small and poor coffee farmers, which is called 'coyote', controlling production, paying unfair prices for labor and goods, and participating in fraudulent practices to maximize their own profits. However, the reality of gains captured by coffee middlemen in the value chain might be exaggerated and even unfair. Therefore, the main aim of this paper is to reconsider the implication of coffee middlemen for the development of coffee value chain in Vietnam. It also attempts to identify their characteristics by investigating relations among coffee farmers, middlemen and processing/exporting firms. In terms of middlemen's margin in the coffee sub-sector, their margin is quite small when compared to other actors higher in the value chain. Rather, coffee middlemen in Vietnam have played a critical role as an intermediary of change in local economies. More specifically, coffee middlemen in Dak Lak has played a significant role as a market facilitator by stimulating the access of farmers to markets by providing buyers for farmers thanks to changes in institutional environment. Also, they have played a critical role as an agent of sustainable coffee production by encouraging sustainable coffee production in accordance with the demand of processing and exporting firms.

In this paper, we investigate industrial product intermediary's transformation strategy by exploiting advantages afforded by web based information technologies. Our motivation for this research stems from exploring intermediary's responding strategy to cope with supplier's threatening to disintermediation. From transaction cost perspective, internet can induce both the vertical quasi-integration (electronic hierarchy) and outsourcing (electronic market). Our rationale on directing one of these bi-directional movements is specified on intermediary's value adding on the supply chain. As such, we investigated supply chain performance, IT effects on customer's requirement of channel functions, and channel power structure. Propositions to suggest contingent e-transforming strategic alternatives are logically derived from dyadic nature of supply chain characteristics such as efficiency versus customer services, and supplier dominant versus easy replaceability of suppliers. The contingent e-transformation framework developed from intermediary's perspective is reviewed through longitudinal industry case analysis. Implications from the industry case analysis give us insights for the effectiveness of the framework to combine supply chain characteristics with intermediary's e-transformation.
