이 연구는 공공부문이 구축/관리중인 지식정보자원의 시민활용 실태를 점검하고 유비쿼터스 기술을 활용한 지식정보자원의 시민활용성 제고방안 모색을 목적으로 한다. 이를 위하여 부산광역시의 시민 200 명을 대상으로 설문조사를 실시하여 지식정보자원에 대한 인지도/활용도/활용장애요인과 유비쿼터스 기술에 대한 인지도/활용도/유용성을 조사하였고, 향후 유비쿼터스 기술을 활용한 공공행정, 교육학술, 사회문화/복지, 생활경제 등 4 대부문 16 개분야 32 개의 지식정보자원에 대한 시민활용 의향을 분석하였다. 분석결과 지식정보자원에 대한 인지도와 활용도는 보통보다 낮은 수준에 있으며, 그 이유로는 개인정보유출에 대한 불안, 지식정보자원 소재에 대한 정보부족, 지식정보자원 활용 비용의 부담 및 활용의 불편 등으로 나타났다. 향후 유비쿼터스 기술을 활용한 지식정보자원 활용의향에 대해서는 실생활과 밀접한 관련을 갖고 있는 교통/기상정보, U-Care 및 U-Health 정보, 금융, 공연예술, 관광여가 등의 정보에 대해서는 높은 의향을 보이나, 실생활과 직접 관련이 적고 전문적인 능력이나 관심이 요구되는 행정정보공개, 정책참여, U-학술연구 등에 대해서는 낮은 의향을 보이는 것으로 나타났다.

This research attempts to explore the competitive advantage of the Busan New Port based on the comparative analysis against the major ports. The competitive environment of the global shipping business poses a variety of challenges for the port authorities. Pursuing the hub position in the Northeast Asia, Busan new port needs an in-depth competitive analysis against the major ports in Singapore and China. This research proposes the strategies to exploit the locational advantage of the port while upgrading the operational efficiency. The recent development of the information technology suggests a viable solution for the Busan port.

With current. difficulties in Korean agricultural sector, the biotecilnoiogy is considered as the most important factor to offset the inferiority in the agriculture. New products by using the biotechnology would be commercialized and consumed by both producers and consumers. Before its production and distribution researches on new product should be undertaken in many aspects, especially in terms of economic aspects. Main objectives of this study are to measure the economic value of the new product using the agro-biotechnology, here potato microtubers, and to examine whether the stated preferences theory, the Contingent Valuation Method(CVM), could be accepted in the economic analysis for the new biotech product. Through the demand function derived from the consequences of functional relationship, the consumer's surplus was estimated.

지난 몇 십년동안 전 세계적으로 제조기술 분야의 급속한 성장으로 대부분의 제조업에서 눈부실만한 품질향상과 생산성 극대화를 이루어 왔다. 하지만 현재 제조기술 분야는 새로운 문제에 직면하고 있다. 실제 현장에서 관리하고자하는 품질특성은 정규분포를 따르지 않는 경우가 많은데, 대부분의 통계적 공정관리기술체계가 정규분포를 기반으로 하고 있다는 것이다. 이러한 이유로 비정규 공정에서 극소불량관리, 미세변동관리에 대한 연구가 시급한 실정이다. 하지만 비정규 분포를 통계적으로만 해석하고 설계하기 위해서는 현실적으로 한계가 있으며, 경제적 설계의 접근방법이 또 하나의 좋은 대안이 될 수 있다. 본 논문에서는 비정규 공정에서 관리도의 경제적 설계를 위한 연구동향을 살펴보고 추후 연구방향에 대해 제시하고자 한다.

Technology standard continues to exist as an social agreement throughout all industry. With development of Information and Communication, it is recently considered as a strategic factor for enhancing interoperability and increasing market dominance. Hence, technology standard research(standardization research) have a significance in analyzing the process of standard adoption and its economic effect and deriving theoretical and policy implications. However, as existing relative researches are lack in consideration on indigenous value of technology and its interoperability, there exists limitation in drawing the result of technology centered analysis. The goal of this study is to suggest new technology centered standard method by implying function of technology differentiation rate and technology preference that are deduced by technology network analysis into two stage game theory. As an example of empirical case, we selected wireless pan technology of Internet of Things, and derive its technological structure and implications related to standard.

This research seeks to investigate the economic feasibility of a small size aircraft development and BASA certification enterprise. To achieve the objective, this research investigates cost which requires for proceeding a small size aircraft development and BASA certification enterprise. This research also investigates the economic effects and economic benefits acquired from exporting civil aircraft. Costs and benefits are assumed using cash flow by types of airplanes. On the basis of the cash flow, this research calculates B/C ratio, NPV, IRR for investigating the economic feasibility. The result shows that there are economic feasibility for both very light jet and piston aircraft. Between these two aircraft types, more economic feasibility exist for very light jet than piston aircraft.

This research focus on estimating the economic effects of TOD system development from the perspective of new market creation, R&D planning cost reduction and increase of R&D projects' commercialization success rates. The research is conducted through simulation and scenario analysis with assumptions about economic effect parameters. Scenario analysis shows that scenario 1 (the application ratio of the new TOD system to total Korean R&D programs' planning is 1.4%) results in total economic effects, 921.3 billion won in 2011 price with B/C ratio 6.15, that scenario 2 (the application ratio is 1.9%) results in total economic effects, 1,250.3 billion won in 2011 price with B/C ratio 8.34, and that scenario 3 (the application ratio is 0.9%) results in total economic effects, 592.2 billion won in 2011 price with B/C ratio 3.95. The research contributed to the prior evaluation of economic validity of "R&D on Technology Opportunity Development (TOD) system" and to cultivating the new methodology of economic benefit estimation in the area of R&D on system development.

Recently, as climate change caused by greenhouse gases is intensifying, the international community has committed to reduce greenhouse gas emissions. The purpose of this study is to present the methodology and major considerations for investment judgment. Two actual cases of overseas projects were selected as study subjects. As an analysis method, the major risk factors were defined as a probability distribution, and the NPV was stochastically estimated using the Monte Carlo simulation method. In addition, assuming a policy change, the range of NPV change was analyzed. As a result, the average NPV of project A was lowered by 19%, and the probability of showing a negative NPV was 12.2%. The average value of project B was lowered by 12.5%. Considering the policy change, project A can obtain economic benefits only when it obtains 72.9% or more of the total amount of carbon credits generated, and project B is economically feasible when it acquires 49.5% or more. As a result, the average value of project A is lower than the net present value under basic assumptions, so caution is needed in investment decisions depending on changes in major risk factors. Additionally, considering policy changes, the carbon credit distribution ratio should be differentially applied depending on the project size, and this was presented as a specific figure.

에너지 시스템의 도입 목표는 에너지 사용자 및 국가적인 측면에서 차이가 있을 수 있다. 따라서 에너지 수급 및 이용의 효율화를 추구하는 국가 에너지 정책의 실현을 위하여는 정부는 성에너지성이 우수한 지원에 인색하여서는 안된다. 특히 에너지 시스템 도입의 국가적 목표를 에너지 사용자 측면에서 강조되어야 할 경제성에 두고 에너지 정책을 수행하여 나간다면 국가적인 차원에서 성에너지화는 불가능하게 됨에 유의하여야 한다.
