최근 기업은 저장된 데이터를 비즈니스 인텔리전스 기반으로 통합하고 분석한다. 이를 위해서 기업들은 ETL(Extraction, Transformation, Loading) 기술을 이용하여 다양한 소스로부터 데이터를 추출하여 변환한 후 데이터웨어하우스에 저장한다. 그러나 데이터웨어하우스/데이터 마트 기반 비즈니스 인텔리전스 프로젝트들은 기존의 사용하던 툴이 기능상의 한계를 드러내면서 시스템 통합, 마이그레이션, 동기화 등의 어려움이 있다. 특히, 서로 다른 ETL 툴을 사용하는 경우 메타데이터의 통합, 데이터 실시간 동기화 기술, 데이터 표준화, 데이터 매칭 등이 어려워 부분적으로만 지원되고 있는 실정이다. 본 논문에서는 다양한 데이터 통합 및 추출, 변환하여 데이터웨어하우스에 저장할 수 있는 XMDR-DAI를 제안한다.

As the domestic consulting industry matured, consultants were required to have insight into customer's business and consulting business. Gaining these insights requires deep understanding of the business domains and high degree of competencies. This study empirically analyzed the data collected through the survey in order to apply the ICMCI competence model to domestic consultants. As a result of the study, it was found that business competency and technical competency had a positive effect on project performance, but values & behavior competency were not statistically significant. On the other hand, it was found that only technical competency, values & behavior competency had a positive effect on social-relational competency. Through this study, it was confirmed that a deep understanding and perception of the consulting business is necessary to grow into a professional consultant, but there is a limit to generalizing the research results because the characteristics of the population cannot be sufficiently reflected with a small sample.

With the penetration of the Internet and e-commerce, a 'crowdfunding' has emerged as a new way of financing. Crowdfunding has the advantage for a person to able to a simple way to finance her/his an innovative product or service from crowd. However, the success rate for crowdfunding projects is less than half. In this study, we introduce social exchange theory to explore the impact of trust and perceived psychological risk on the intention to participate in a crowdfunding website. Different from previous studies that have focused on a crowdfunding creator, we consider two different perspectives of a project creator and a project supporter. In addition, we compare perceptions of crowdfunding in different cultural contexts by conducting survey in two different countries Korea and Austria. Result shows that trust in recommendation and trust in website have different impacts on the intention to participate from two different perspectives. It also shows that perception of the quality and transparency of information provided by crowdfunding website has greater impact on trust in Korea than that in Austria. In case of perception of psychological risk, it has a negative impact on Austria's intention to create or support a project. On the other hand, it has relatively small impact on the intention to support and does not affect the intention to create a project in Korea.

This study presents a FZOGP(fuzzified zero-one goal programming) model and a DHP (Delphic Hierarchy Process) that can be used to help information systems(IS) managers decides which IS projects should be selected. Delphic method is conducted prior to AHP so that not only can the objectives to be considered in analysis be determined, but the opinions of all decision makers can also be incorporated in problem formulation. While the DHP provides an ideal ranking process for the selection of IS Projects, it does not consider real constraints that exists in decision making process. Then this study intends to show how the DHP can be used to establish a priority structure for use within a FZOGP model. The advantages of FZOGP model are as follows: the imprecise aspiration level for each objective can be considered in FZOGP model. And, the common features between the new FZOGP and the GP models are that the objective functions in both models are minimized and the structure of their formulations are the same.

Changes have occurred in the professional capabilities of the construction project managers after the global financial crisis. As representatives of construction companies and projects, construction project managers have full responsibility over a construction project. Throughout its life cycle, from design through construction to completion, the business capabilities of such managers are regarded as critical elements in the changes in the country's construction economy. Therefore, this study aimed to determine the main capabilities of current construction project managers, and to analysis of its competitiveness using Important-Performance Analysis(IPA). The results of IPA were as follows; (1)capability to win new contracts and capability to collect information of new project are needed for external relation competitiveness, (2)gerentocratic management mind-set and active breakthrough are needed for internal project management competitiveness, and (3)capability to predict issues and self-improvement are needed for self discipline competitiveness. However, this work is still considered to provide the basic data that can help Korean construction companies who plan to educate the project manager's strengthen their medium and long-term capabilities.

Single window has become a critical point of trade facilitation. While Korea has set up the first web based single window 'uTtradeHub', China has also been working on a seamless single window. As strong governmental support, advanced technology, leading agency and legal framework are success factors for single window, China already has solid foundation for this. For the leading agency, this research suggests the CIECC as a leading agency with linkage to E-Port service for seamless trade service for companies. We expect that Chinese single window will materialize in near future by a leading agency with the help of strong governmental support.
