데이타베이스 관리시스템에서 중요한 문제중의 하나는 효율적인 버퍼관리이다. 데이터베이스 관리시스템에서 객체를 디스크에서 읽어오는 작업은 많은 비용을 필요로 하기 때문에 시스템의 성능을 향상시키기 위해서는 디스크 I/O의 횟수를 최소화하는 것이 매우 중요하다. 지금까지 디스크 I/O 횟수를 줄이기 위한 많은 버퍼관리기법들이 제안되었지만, 그 기법들은 시간적 근접성만을 고려하기 때문에 공간적 근접성도 존재하는 공간데이타베이스 환경에서는 좋은 성능을 보여주지 못했다. 본 논문에서는 공간데이타베이스의 시간적 근접성과 공간적 근접성을 동시에 고려하는 새로운 버퍼관리기법인 Spatial Locality Area Measure(SLAM) 기법을 제안한다. 제안한 버퍼관리기법은 SLM-tree와 M-LRU, 두 개의 구조체로 구성되었으며 공간데이타베이스 환경에서의 다양한 버퍼크기와 참조빈도에 대한 실험에서 뛰어난 성능을 보여준다.

Environmental differences across countries such as socio-cultural, political, economic, and technological differences require business strategies of multinational corporations to vary business practices across regions. Despite the keen awareness of the necessity for strategic adaptation to local context, IS management and strategy tend to remain similar across countries. One of the reasons is to maintain the stability and compatibility of information technology infrastructure. After a careful observation of retail business practice, this study finds IS strategy should also be highly responsive to the local context. This study shows how information resources including systems architecture, processes, human resources, and national context are interlinked together. Despite global excellence in general systems management, failure in such alignment can be a serious problem in extending competitive advantages across regions. This study aims to reveal issues to be taken care of in order to accomplish global technological alignment. Results of this study provide senior management with guidelines and a framework for aligning IT with regional strategic thrust that can improve local responsiveness of multinational companies.

브랜드는 고객들 사이에서는 프리미엄을, 투자자들에게는 주가 프리미엄을 제공한다. 나아가 매출을 늘리는 역할까지 하면서 기업의 성과를 가름하는 중요한 요소가 되고 있다. 돌비가 40년전에 내놓은 '기술의 라이센스 판매'라고 하는 발상과 비즈니스모델은 곧 인텔의 프로모션전략 '인텔인사이드'로 나타나고 샤프의 '플라즈마클러스터'전략의 마중물이 되었다. 그것은 기술이라고 보기 어려운 자산을 라이센스 하는 것 뿐만 아니라, 그것을 브랜드로 하기 위한 여러 가지 커뮤니케이션 활동 이나 매니지먼트 전략을 조합하여 발전시킨 것으로 시장에 있어서 경쟁우위의 취득과 장기수익의 확보에 유효한 것을 증명한 것이다. 테크놀러지 브랜드 마케팅이라고 하는 발상과 이론은 아직까지 많은 연구가 되고 있지 않으며 더구나 국내에서는 더 더욱 생소한 개념이라고 하겠다. 그러나 테크놀러지브랜드 마케팅은 확실히 기능 하고 있는 것을 알게 되었다. 결코 돌비나 인텔과 같이 명확한 의사를 가지고 진행되어진 것은 아니지만 많은 기업이 어떠한 방법으로든 자사기술의 브랜드화를 취하여 왔다. 여기에서 기술브랜드 마케팅으로 고객에게 신뢰를 얻으려고 노력하는 일본의 선진기업의 산업별 기업의 사례와 그 가능성에 대해 소개하여 동일업종의 국내기업들, 특히 창업기업에 있어 초기경영단계에서 부터 마케팅 전략도구로의 활용방안을 제시하여 본다.

InnovVizwas designed and developed anew as avisualization and simulationtool to present innovation and strategy information. The InnovViz system employs two key types of technology, namely mixed reality (MR) and neural network (NN). An experiment was conducted to examine the usability, acceptance and possible adoption of this new system. Participants comprised 4 experts from 4 top performing entrepreneurial firms and 161 master degree students from 2 leading universities. The study used a modified UTAUT model and a cognition and perception model. The results revealed that when the InnovViz was introduced, the key drivers to adoption are Facilitating Conditions (FC) and Voluntary to Use (VOL). Adequate knowledge and sufficient resources were found to strongly affect FC construct. The expert's rating of a firm's innovation and performance was more congruent with senior students with a technology-background than with a finance and accounting-background. InnovViz was seen as providing complex information with an ease of use and usefulness for showing data and assessment. Among the three types of visuals depicted by InnovViz, experts rated their usefulness in descending order as follows: Cube, Tetrahedron and Saturn. Finally, experts found backward simulation to be slightly more useful for assessment than forward simulation.

In the context of the convergence revolution that brings together culture, technology, and humanities, the fashion industry is aiming to form product strategies to create added value. The ultimate aim of these strategies is to satisfy consumers' diverse needs. Boosted by discussions on sustainability in the fashion industry, sustainability management activities are also emerging as a trend in product strategy. Therefore, it is important to consider both convergence and sustainability management activities together as drivers of fashion brands' product strategies. The main objectives of this study are as follows: (1) to examine the differences in sustainability evaluation by product strategy, (2) to determine how sustainability evaluation affects brand attitude and purchase intention, and (3) to identify how this effect varies according to the types of convergence and sustainability management activities. The main findings of this research are as follows. First, sustainability evaluation varies according to fashion brands' product strategy. Second, evaluation has a positive effect on brand attitude and purchase intention. Third, the effect varies according to the types of convergence and sustainability management activities. This study is an extension of previous research for combining fashion brands' convergence and sustainability management activities as a part of their product strategy, which, in turn, contributes to positive consumer responses on the marketing level. Moreover, results provide practical implications for fashion brands that enable them to establish efficient marketing strategies regarding to convergence and sustainability management activities.

To establish an effective security strategy, business enterprises need a security benchmarking tool. The strategy helps to lessen an impact and a damage in any threat. This study analyses many aspects of information security management and suggests a way to deal with security investments by considering important factors that affect security manager's decision. To address the different threats resulting from a major cause of accidents inside an enterprise, we investigate an approach that followed ISO17799. We unfold a criminology theory that has designated many measures against the threat as suggested by General Deterrence Theory. The study proposes a coherent model of the theory to improve the security measures especially in handling and protecting company assets and human lives as well.

This study aims to analyze which subsidiary configuration strategy is more effective under uncertainty especially technology base multinational corporations (henceforth MNCs). In previous studies real option theory scholars argue that high breadth subsidiary configuration is most effective strategy because that provides flexibility to MNCs global network. In this study I want unveil more various types of uncertainty such as technology and learning uncertainty which are more important for technology base firm and further more examine the effect of MNCs subsidiary configuration on firm R&D performance each uncertainty case. Empirical study is performed by negative binominal model based on Japanese 108 multinational corporations. The result shows that under technology uncertainty, high breadth subsidiary configuration is better for firm R&D performance but under learning uncertainty high depth subsidiary configuration is better. Thus, the effects of MNCs subsidiary configuration on firm value can differ by types of uncertainty.

This paper proposes an energy management strategy and adaptive control for superconducting magnetic energy storage (SMES) in a distribution power system with a grid-connected photovoltaic (PV) farm. Application of the SMES system can decrease the output power fluctuations of PV system effectively. Also, it can control the real and reactive powers corresponding to the scheduled reference values with adequate converter capacity, which are required at a steady-state operating point. Therefore, the adaptive control strategy for SMES plays a key role in improving the system stability when the PV generation causes uncertain variations due to weather conditions. The performance of proposed energy management strategy and control method for the SMES is then evaluated with several case studies based on the PSCAD/EMTDC$^{(R)}$ simulation.
