본 논문에서 이론적으로 분석하고자 하는 기술포트폴리오 매트릭스는 기술매력성(계속적 개발잠재성, 응용범위, 호환가능성)과 자원강도(지배범위, 잠재성, 반응속도)에 기초한 기술투자 분석 또는 전략적 기술관리를 위한 유용한 의사결정 수단이다. 즉, 기술포트폴리오는 국내기업뿐만 아니라 현지투자기업의 연구개발과 관련된 의사결정을 위하여 활용될 수 있다. 특히, 본 연구에서는 글로벌 기업에 있어서의 본사 및/또는 현지자회사간의 기술포트폴리오 매트릭스를 분석함으로써 글로벌 기업의 기술포트폴리오 관리를 위한 방법을 제시하고자 한다.

A fixed k-coloring problem is introduced and dealt with by efficient heuristic algorithms. It is shown that the problem can be transformed into the graph partitioning problem. Initial coloring and improving methods are proposed for problems with and with and without the size restriction. Algorithm Move, LEE and OEE are developed by modifying the Kernighan-Lin's two way uniform partitioning procedure. The use of global information in the selection of the node and the color set made the proposed algorithms superior to the existing method. The computational result also shows that the superiority does not sacrifice the time demand of the proposed algorithms.

Advances in information technology (IT) are becoming one of the most significant driving forces changing the structure of global financial management. This phenomenon is occurring in all industries ; the hotel industry is no exception and must quickly adapt to this new trend. This study discusses IT investment in the hospitality industry with a particular emphasis on assessing the value of IT investment and its investment strategy.

Firms pursue new business opportunities for growth. Market development strategy is one of the growth strategies, which develops new market segments with current products. However, new market generally has high uncertainty, or high risk. Firms should consider the risk in making and implementing the market development strategy. In this paper, an optimal marketing resource allocation model is developed, taking into account the risk attitude of a firm in market development. Under the assumption of exponential utility function, the global optimal solution is derived, and the implications are provided.

As the importance of technology planning has been increased, the various methods of the technology planning have been developed by global leading companies recently. The goals of companies are set after investigating market and customer. And finally, a strategic roadmap is diagrarnrnatized as a picture to show how to accomplish them based on technology forecasting.

Fierce competition in today's global markets, the heightened expectation of customers have forced business enterprises to invest in, and focus attentions on, their Supply Chains, Also Cross Docking is an essential part of SC, and integrating Cross Docking with vehicle routing scheduling is needed to smoothly link the physical flow of SC, However, there is no the mathematical model which focuses on Cross Docking with vehicle routing scheduling. Therefore, the integrating model considers Cross Docking and vehicle routing scheduling will be developed in this paper. And the solution based on Tabu algorithm to this model will be provided.

In this paper a face optimization algorithm is developed for solving the problem (P) of optimizing a linear function over the set of efficient solutions of a multiple objective linear program. Since the efficient set is in general a nonconvex set, problem (P) can be classified as a global optimization problem. Perhaps due to its inherent difficulty, relatively few attempts have been made to solve problem (P) in spite of the potential benefits which can be obtained by solving problem (P). The algorithm for solving problem (P) is guaranteed to find an exact optimal or almost exact optimal solution for the problem in a finite number of iterations.

In this paper a face optimization algorithm is developed for solving the problem (P) of optimizing a linear function over the set of efficient solution of a bicriterion linear program. We show that problem (P) can arise in a variety of practical situations. Since the efficient set is in general a nonoconvex set, problem (P) can be classified as a global optimization problem. The algorithm for solving problem (P) is guaranteed to find an exact optimal or almost exact optimal solution for the problem in a finite number of iterations. The algorithm can be easily implemented using only linear programming method.

This paper introduces a vehicle-following-system in which a moving vehicle recognizes the front vehicle's tail-light color and luminance, while maintaining a certain distance and avoiding collision. Using color images rather than using gray-scale images makes it easier to detect the objective color and eliminates the need of a thresholding. The Methods used are RGB to HSV conversion and global region growing method. This paper contributes to the basic study of Color-Vision, and can be extended to color inspection systems.

KSCD(Korea Science Citation Database)를 기반으로 국내 과학학술지 논문에 대한 인용색인을 구축하였으나, 국내 학술지에 대한 인용현황만으로는 연구자들이 원하는 자신들의 논문의 인용현황을 포괄적으로 알기 어려우므로 해외 인용현황을 알기 원하는 요구에 부응하기 위해, WOS의 API를 활용한 인용현황 서비스를 구현하였다. 이에 기반하여 그 결과에 대한 데이터 분석을 수행하고 국내연구자의 SCI 전체 논문 분석결과와 비교하였다.
