Firms can make scale of economy and scope of economy by internalizing and using new advanced technology and knowledge from technology cooperation network, decrease risk and cost with partner firm of technology cooperation network, and increase market advantage of product & strengthen firms' position in the market. Due to the advantages of technology cooperation network, the related studies have focused on the positive effect of technology cooperation network. However, the related studies investigating the relationship between technology cooperation network and firm performance have only examined the role of technology cooperation network. Safeguarding mechanism, relationship learning, and relationship performance are categorized into the process of technology cooperation network, and this categorization is applied as resources, capability, and performance by resource based view. The empirical results are reported as belows. First, relationship specific investment and relationship capital positively affect on relationship learning as capability. Second, information sharing, common information understanding, and relationship specific memory development positively affect on long-term orientation, but information sharing has no impact on efficiency and effectiveness. Third, relationship specific investment positively affects on relationship capital and efficiency and effectiveness have positive effects on long-term orientation. Applying technology cooperation network in asymmetric technology dependency with resource based theory, this study suggested the importance of both safeguarding and relationship learning by investigating the relationship among safeguarding, relationship learning, and relationship performance. And it is worthy that this study investigated how firms' behavior change affects relationship performance in the relationship of technology cooperation partner.

This study is to identify the relationship in non-profit social welfare organizations(SWOs) between financial sources and service delivery. Especially the impact of the former to the latter is its main concern. For this purpose, gathered are the 1992, 1999 financial reports of those study organizations, and some qualitative data on a number of the organizations collected by the author is also used for verifying and interpreting the data. Gronbjerg's study(1992) provided an analytical tool for decomposing financial structure of human service organizations, and resource-dependency perspective was a theoretical framework for interpreting the impact of financial composition to service delivery. The findings are as follows: (1) Between 1992 and 1999, there was a noticeable change in financial composition among SWOs. Government subsidies has increased in terms of both amounts and percentages, for residential facilities 75% to 82% and for nonresidential facilities 37% to 47%. Funding from donations shows no abrupt changes, although absolute amounts were slight increasing. Fees were sharply decreasing, especially for the non-residential facilities which previously enjoyed them as valuable resources for preventing unnecessary influence from government. (2) The funding sources of SWOs and their strategies to acquire them has impact on service delivery. Although non-government fundings(donations and fees) were found to give elasticity to SWOs, various problems associated with acquiring them (i.e., changing the clientele) would prohibit SWOs from fully concentrating to those fundings. Meanwhile, government fundings are characterized as stable, and, as such, most of the SWOs prefers. Limited elasticity, red-tape, 'sacrifice of quality of service' over efficiency, etc. are referred to the problems.

The scheduling problem that maps independent tasks to heterogeneous resources in distributed computing systems is known as NP-complete［1］. GRID［2］ is an example of distributed systems that consisted of heterogeneous resources. Many algorithms to solve this problem have been presented［1,3,4,5］. The scheduling algorithm can be classified into static scheduling algorithms and dynmic scheduling algorithms. A dynamic scheduling algorithm can be used when we can not predict the priority of tasks. Moreover, a dynamic scheduling algorithm can be divided into on-line mode algorithm and batch mode algorithm according to the scheduling time［1,6］. In this paper, we propose a new on-line mode scheduling algorithm. By extensive simulation, we can see that our scheduling algorithm outperforms previous scheduling algorithms.

본 논문은 지구의 지속적인 발전을 위해서 지구환경문제인 지구온난화 방지에 대한 방법으로 이산화탄소 저감을 위한 방안에 관해서 검토하였다. 지속가능성을 위협하고 있는 빈부의 격차를 축소하고 동시에 지구온난화에 대한 환경개선을 국제적인 틀 안에서 환경비교우위에 기초한 산업구조의 조정과 공동이행활동이라고 하는 방안을 제안하고, 이러한 방안에 관해서 분석평가하고 비교한 것이다. 구체적으로는 이산화탄소 문제를 지구 전체 문제라고 가정하고 방안을 강구하였다. 국가간의 GNP와 고용에 미치는 영향은 최소한으로 하면서 이산화탄소 배출량을 줄이는 양국의 산업구조를 명확하게 한 것이다. 더욱이 남북문제도 동시에 해결한다는 것에 착안해서 이론전개를 하고 있다. 따라서, 여기서는 환경비교우위의 개념을 응용해서 부가가치단위당 이산화탄소 배출이 상대적으로 적은 부문(환경적 우위 부문)에 생산을 특화하고 이것과 반대의 환경적 열위부문에 대해서는 상대국으로부터 수입에 의존하는 것에서 국제적으로 이산화탄소 배출이 적은 산업의 재배치를 실현하는 것이 가능하다라고 하는 논리전개로부터 그 결과를 명확하게 하였다. 또한, 지구환경개선을 목표로 하는 또 하나의 전략인 공동이행활동에 관해서 분석하였다. 이것에 관해서는 경제적으로 온실효과가스를 줄인다는 것뿐만 아니라 선진국에서 개발도상국으로의 기술이전을 촉진하고 남북격차를 시정한다는 점에서 기대가 크다는 것에 착안하고 게임이론을 통해 일본과 중국의 실제 데이터를 사용하여 공동이행활동의 가능성을 평가하였다. 이러한 두 가지 방책의 특징을 검토하여 효율적인 방안을 제시하고 그 방안에 대하여 고안하고 시뮬레이션 분석을 하였다. 그 결과 융합방안에서는 상술한 환경비교우위의 정학적 분석결과와 공동이행의 게임분석결과를 고려하고 확장된 공동이행 게임의 균형점까지 자원의 원조를 한다는 전제조건하에서 2010년까지 이산화탄소 배출량 추이를 산정한 결과 융합방안이 보다 효율적이라는 것이 판명되었다. 이러한 내용을 바탕으로 본 논문에서는 현재 지구 온난화 문제의 해결에 있어서 걸림돌이 되고 있는 남북문제의 격차와 협력에 관한 곤란한 문제에 착안해서 환경적 우위와 융합방안이라고 하는 새로운 방안을 제안하였다. 그리고 각각의 방안에 대해서 상세히 분석하고 일본과 중국을 모델로 실제 정책으로의 실현가능성을 분석하였다.

In order to guarantee system survivability against attacks based on new methodology, we need a solution to recognize important resources for essential services and to adapt the urgent situation properly. In this paper, we present a dynamic resource reallocation scheme which is one of the core technologies for the implementation of intrusion tolerant systems. By means of resource reallocation within a node, this scheme enables the essential services to survive even after the occurrence of a system attack. If the settlement does not work within the node, resource reallocation among nodes takes places, thus the essential services are transferred to another prepared server node. Experimental result obtained on a testbed reveals the validity of the proposed scheme for resource reallocation. This scheme may work together with IDS(Intrusion Detection System) to produce effective responsive mechanism against attacks.

Competitiveness of a firm essentially depends on the value of the product or service the firm supply. Product or service of high value derives customer purchase activity. Service mix is the process which creates competitiveness by value creation for customers through optimal combination of physical characteristics of product and service. This research is to contribute competitiveness increase of Korean manufacture industry by study of the effect of service mix as to the business competitiveness. Usually competitiveness advantage approach relies on the industry structure competition theory and the resource-based approach. However, it is said that, while the industry structure competition theory helps finding attractive industry, it rarely helps finding which companies succeed or fail in the specific industry. The resource-based viewpoint approach is limited in that this cannot provide any theory or systematic frame for the analysis even though it has contributed a lot to the competitiveness increase. Power process approach is applied to this study in order to overcome this limit and to Increase the business competitiveness. Power process is the process to create the value, the source of power by interaction of power elements, value, needs, environment and relation, the five power determination elements. Power process is a process that creates value to satisfy the power objective for the attainment of the goals of the power subject. This study is to contribute for the manufacture industry by establishing service mix strategy from the power process viewpoint.

The mathematical models for GIS-based spatial data integration have been developed for geological applications such as mineral potential mapping or landslide susceptibility analysis. Among various models, the effectiveness of fuzzy logic based integration of multiple sets of geological data is investigated and discussed. Unlike a traditional target-driven fuzzy integration approach, we propose a data-driven approach that is derived from statistical relationships between the integration target and related spatial geological data. The proposed approach consists of four analytical steps; data representation, fuzzy combination, defuzzification and validation. For data representation, the fuzzy membership functions based on the likelihood ratio functions are proposed. To integrate them, the fuzzy inference network is designed that can combine a variety of different fuzzy operators. Defuzzification is carried out to effectively visualize the relative possibility levels from the integrated results. Finally, a validation approach based on the spatial partitioning of integration targets is proposed to quantitatively compare various fuzzy integration maps and obtain a meaningful interpretation with respect to future events. The effectiveness and some suggestions of the schemes proposed here are illustrated by describing a case study for landslide susceptibility analysis. The case study demonstrates that the proposed schemes can effectively identify areas that are susceptible to landslides and ${\gamma}$ operator shows the better prediction power than the results using max and min operators from the validation procedure.

Clients' outsourcing strategies noted in the IT outsourcing literature generate varying levels of client dependence on vendors. This study investigates clients' efforts to mitigate such dependence by utilizing multiple vendors. We use the theoretical lenses of resource dependency and opportunism to study this phenomenon. Specifically. we consider degree of outsourcing, duration of contract, and externalization of control as strategic choices that engender vulnerabilities that clients seek to offset by using multiple vendors. This study then considers the basis of the outsourcing relationships, clients' satisfaction with the relationships. and clients' IT workforce size as conditions that induce clients' concerns about vendor opportunism. This study argues that these conditions can exacerbate clients' experience of vulnerability. further encouraging clients' use of multiple vendors. The research model developed is tested in a survey of firms in South Korea. Results suggest a strong impact of outsourcing strategic choices on the number of vendors used by clients. The anticipated moderating effects of opportunism were only weakly supported by the data though. Theoretical and practical implications of the results are considered and suggestions for future research are offered.

This study analyzed the factors influencing the technology transfer of Government-Funded Research Institutes from the perspective of resource-based view. In particular, we analyzed the effects of research resources, research capacity, and research results diffusion variables on technology transfer performance. The research resource variables affect the primary output of R&D (patents, research papers) but direct effect on the technology transfer performance was very weak. Among the research competency variables, patent-related variables such as patent registration, patent holdings have a significant effect on the technology transfer performance. However, the research papers have a negative effect on the technology transfer performance. The research results diffusion variables such as TLO organization and TLO budget may partly have a positive impact on technology transfer, but the statistical significance is not clear.
