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.

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 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.

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.

The current study attempts to provide the field of knowledge management with theoretical grounds from the perspective of social network, resource dependency, and institutional theory. Social network theory considers that knowledge management plays a critical role in organizational innovation through the process of knowledge sharing/creation, communication systems, and a cooperative culture and trust, whereas resource dependency perceives knowledge management as contributing to cost reduction through the process of knowledge capture/storage, database systems, and reward/incentive systems. Plus, from the perspective of institutionalization, this study discusses that organizations can not benefit from knowledge management if it is adopted with the motive of isomorphic change. Finally, this study compares and integrates the three perspectives, and discusses the implications and limitations.

This study investigated population characteristics that influencing treatment service use of people who are voluntarily using drug dependency treatment services by using logistic and hierarchical regression analysis. The research model of the current study was driven by the framework of the 'the Behavioral Model of Health Services Use(the Andersen model)' that has been broadly applied to study on health behavior. This study used data from a sample group of 80 adults by using purposive sampling. This study found that some predisposing factors, enabling factors and need factors have direct effects on service use. In detail, individuals who graduated from high school use drug dependency treatment utilities more than those who did not. Further, individuals who were given more support from family, peers, or others, use the treatment utilities more frequently and were more willing to use the utilities continuously. Furthermore, the greater the perceived need felt by the dependent, the greater the tendency to enter hospitals or shelters. The important implications of this study for social work practice and social policy can be summarized as follows: first, this study supports the idea that intervention for drug dependents in Korea should be focused on environment resources rather than population characteristics; and government must support drug dependent treatment systems; the present study was the first to investigate Korean drug dependents through taking a more positive view, as well as the first to apply 'the Behavioral Model of Health Services Use', and as such represents an example of how studies could be productively conducted in the future. Despite these implications, there remain some limitations in this study. These include the following: limitation in generalizability of the results; the cross-sectional nature of the study design; survey research through the questionnaire method; using foreign scales; and the difficulty of classifying treatment settings.

In the present analysis, a number of sun control devices are examined for their performance in promoting the interior visual environment. Two exemplary cases are introduced for their excellence in harnessing the concept of daylighting and passive concepts. Of these, the Johnson Controls branch office building in Salt Lake City manifests the effectiveness of light shelves and clerestory windows in implementing these concepts. Distinct optical characteristics are found for overhangs, light shelves, louvers, and blinds as they interfere with the path of sunlight. Substantial amount of energy could be saved if the fundamentals of these devices are truly understood in their application to residential and commercial buildings. Sustained efforts should be made in this regard by the builders, architects, energy consultants, and educators who make contributions in energy management.

A computationally efficient inversion scheme has been developed using the extended Born or localized nonlinear approximation to analyze electromagnetic fields obtained in a single-hole environment. The medium is assumed to be cylindrically symmetric about the borehole, and to maintain the symmetry vertical magnetic dipole source is used throughout. The efficiency and robustness of an inversion scheme is very much dependent on the proper use of Lagrange multiplier, which is often provided manually to achieve desired convergence. In this study, an automatic Lagrange multiplier selection scheme has been developed to enhance the utility of the inversion scheme in handling field data. The inversion scheme has been tested using synthetic data to show its stability and effectiveness.
