The growing popularity of mobile application has led to researchers and practitioners needing to understand users' mobile application download behaviors. Using large-scale transaction data obtained from a leading Korean telecommunications company, we empirically explore how application download rank, which appears to users when they decide to download a new application, affects their extended mobile application download. This terminology refers to downloading an additional application in the same category as those that they have already downloaded. We also consider IT characteristics, user characteristics, and application type that might be associated with the extended application download. The analysis generates the following result. Overall, a higher rank of a new application encourages the extended application download, but the linear relationship between the rank and the extended application download disappears when critical rank points are incorporated into the model. Further, no quadratic effect of rank is found in the extended application download. Based on the results, we suggest theoretical and managerial implications.

In recent years, many leading corporations are actively adopting IT as competitive resources to improve productivity and processes efficiency with strategic alignments. In effect, IT investment also continues to increase. As a vast growth of IT investment, questions and criticism on recent IT investment results are also rapidly being raised. Especially, improper decision making and management on IT investment may cause negative impact on the company's reputation and finances, therefore companies need reasonable and wise investment decision making on new IT projects. This study applies the conceptual framework of IT governance to IT investment decision making cases to examine how IT investment governance influences the quality of IT investment decision making and how business-IT strategic alignment affects the quality of IT investment decision making. This paper contributes to identify the main factors for reasonable and effective IT investment decision making and expected to provide proper guidelines for IT investment decision making.

1969년 락희개발(주)로 건설업을 시작한 GS건설은 지난 2005년 명칭을 새롭게 바꾼 후 건축, 토목, 플랜트 환경 등에 다양한 사업을 벌이고 있다. GS건설은 지난해 수주 8조2400억원, 매출 5조6300억원을 달성해 수주, 매출업계 1위에 올랐으며 특히 수주잔액이 총 25조 6000천억원으로 향후 4~6년치 매출을 확보해 건설업계의 정상을 질주하고 있다. 이러한 추진력은 올해도 이어져 수주 8조8000억원, 매출 6조원의 신장된 목표를 설정하여 건설업계 1위를 수성하기 위해 최선을 다하고 있다. 또한 GS건설은 탄탄한 재무구조와 높은 브랜드 이미지, 우수한 기술력을 바탕으로 각 분야에서 지속적인 성장을 거듭, 건설업계에 서 새로운 Leading Company로 자리매김할 계획이다. GS건설은 지난해 6월 자재 입출고 현황 등을 매일 전산으로 체크해 공기, 비용, 안전율, 불량률을 획기적으로 줄일 수 있는 종합 건설관리시스템(TPMS)을 도입하여 기술수준과 관리 능력을 향상시킴으로써 차별화된 경영과 함께 시스템 경영으로 Cost Innovation을 꾀하고 있다. 이와 함께 GS건설은 TPMS를 내년 말까지 전 사업장에 정착시킴으로써 시공의 성역화 및 과학화를 주도할 계획이다.

Busan North port is facing crisis due to the opening of the New port. The North Port and NewPort are competing for a limited volume of cargoes and this competition is leading after all to price competition, lowering cargo work fee that may result in the failure of both This paper proposed the balanced development plans, which are the strategies of business tie-up and activation between the North Port and NewPort by introducing the strategy of "co-opetition" and the analysis for the success factor of co-opetition: to solve this operational problems on Busan port. It is found out that activation strategy is more successful co-opetition strategy than business tie-up strategy. The execution for the two co-opetition strategies will lead Busan Port to the balanced development as well as the enhanced competitiveness and will leap Busan port into global hub port as well.

Telematics, one of the so-called New Growth Engine of IT839, is a leading IT service where wireless internet service represented by information and mobility is extended to the area of transportation. To provide telematics service, Telematics service provider have to connect with various Contents Provider or Service Provide server - for example - LBSS(Location Based Service Server), ASPS(Application Service Provider Server), TELICS(TELematics Information Center Server), GMS(Geo-mobility Server), WTPS(World Telematics Protocol Server) and MAUS(Map Air Update Server). Presently, It is nearly impossible or very difficult for the company that are manufacturing and testing telematics device to develop and test telematics solution without connecting Telematics Service Provider, Service Provider, Contents Provider. And, it is very difficult to connect in TSP, CP, SP having the product to be developed. In this paper, we proposed virtual telematics service provider. The proposed Virtual Telematics Service Provider is to provide telematics services and functionalities by integrating telematics servers into TSP gateway virtually. In other words, VTSP is performs with the role of TSP, CP, SP. And the VTSP support integration of telematics servers, interfacing and monitoring between terminal and the integrated servers.

Following this introduction, this paper presents two conceptual and theoretical analyses-(i) CSR and its relation to profit and charity (ii) CSR as part of a service business model. The paper then illustrates these concepts using a comparative study of four service firms, with particular emphasis on their different CSR activities and how these affect the mission of each company. All four of the service companies are global actors with strong Service Brands (Edvardsson, Enquist and Hay, 2006) and a leading position in using CSR as a driving force for doing business: IKEA, Starbucks, H&M and the Body Shop. The paper then draws together the conceptual analysis and the case studies in a discussion of how CSR can be a proactive driver in the service business. Because of the limit space for a QMOD paper the focus is on the conceptual and theoretical analysis part and the empirical part and discussion/conclusion has to be further developed.

Since delamination often propagates at the interfacial layer between a surface skin and a foam core, a crack arrester is proposed for the suppression of the delamination. The arrester has a semi-cylindrical shape and is arranged in the foam core and is attached to the surface skin. Here, energy release rates and complex stress intensity factors are calculated using finite element analysis. Effects of the arrester size and its elastic moduli on the crack suppressing capability are investigated. Considerable reductions of the energy release rates at the crack tip are achieved as the crack tip approached the leading edge of the crack arrester. Thus, this new concept of a crack arrester may become a promising device to suppress crack initiation and propagation of the foam core sandwich panels.

In this paper, nonlinear vibration behaviors of multi-phase Magneto-Electro-Elastic (MEE) doubly-curved nanoshells have been studied employing Jacobi elliptic function method. The doubly-curved nanoshell has been modeled by using nonlocal elasticity and classic shell theory. An exact estimation of nonlinear vibrational behavior of smart doubly-curved nanoshell has been obtained via Jacobi elliptic function method. This method can incorporate the influences of higher order harmonics leading to an exact estimation of nonlinear vibration frequency. It will be indicated that nonlinear vibrational frequency of doubly-curved nanoshell relies on nonlocal effect, material composition, curvature radius, center deflection and electro-magnetic field.
