Recently as the advent of knowledge-based competition, the major industrialized countries including Korea, are expanding their R&D investment and promoting policies for diffusing of R&D performance. For this, NASA, DoD and such agencies in the United States define Technology Readiness Level (TRL) as a quantified indicator for performance management, and also impose Technology Readiness Assessment (TRA) as a evaluation system, that evaluates technology maturity using TRL. These tools are judged to be very effective in R&D projects especially with the object of practical use. When this concept is applied to the domestic national construction and transportation R&D project for the purpose of practical use, it is expected that the evaluation system overcomes its weakness of focusing only on academic results and improves significantly on intent of achieving practical use. Thus in this study, TRL/TRA implementation model of construction and transportation R&D project for achieving purpose of practical use is presented through an analysis of TRL/TRA concept and domestic national construction and transportation R&D project's characteristics and current evaluation/management system.

The aim of this paper is to explore limits to the institutional formation and operation for network city as a case study of Daegu-Gyeongbuk Free Economic Zone (DGFEZ) in the introductory context. The legal and institutional framework of FEZ in Korea can be characterized by multi-dimensional, vertical or horizontal governance. However, in terms of its implementation process of DGFEZ, the density of the public-private network becomes relatively week, and consequently, the level of participation by local people was not institutionalized in a more collaborative way. With respect to the network city for DGFEZ, while at the initial stage its plan was highly focused upon the conceptual framework of the city, the process of its implementation was based upon a polarization strategy of individual unit and a performance-oriented type. Other evidence for it is that administrative organization in DGFEZ changed from development-based throughout investment attraction-focused up to region-based department. Therefore, there are limits to the institutional formation and operation for the network city in the context of DGFEZ.

Conflicts in the construction of large public facilities carried out as national projects are crucial issues we have to deal with. There are growing concerns for and oppositions to large construction projects in terms of environmental deterioration and the dissolution of local communities. In the case of projects that promise the creation of jobs and investment, the competition and disputes are increasing and being intensified. Therefore, there is a considerable amount of study on the competitions and conflicts between regions. Previous studies have focused on the procedures of public policy, governance structure, the role of local media. Contrary to the previous studies, this study investigates the spatial ways of constructing conflicts. Based on the analysis of the project of "Southeastern New International Airport", there is a mismatch between the spatial boundary of cost/benefit and agents (regions) of disputes. The agents of conflicts also show the politics of multiple scales by constructing alliances and breaking the network in the process of the airport project. The findings suggest that the conflicts on regional development should be understood as the construction of dynamic regional politics on regional development rather than as the by-product in the practice of policies.

일반적으로 기술융합이라는 용어는 IT, BT, NT 등 성격이 다른 큰 범주에서 기술간의 결합으로 인식되고 있다. 현재까지의 기술융합 연구들은 IT기술을 중심으로 한 융합과 관련 국가 정책에 관한 것이 대부분을 차지하고 있어 큰 기술 범주 위주에 국한되어 있다. 하지만 동일한 목적을 위해 수행하는 유사 기술영영에서의 기술융합 역시 기술혁신의 수단으로 간과할 수 없는 영역이다. 실제로 미국, 유럽 등의 선진국에서는 기술융합 전담기관을 신설하여 프로젝트 내의 기술간 융합에 관심을 갖고 있지만, 국내에서는 프로젝트 범위의 기술융합 가능성 및 실효성에 대한 연구가 부족한 실정이다. 이에 본 연구에서는 지식경제부에서 수행하는 가스하이드레이트 연구개발사업을 실증사례로 하여 프로젝트 범위의 기술 융합에 관하여 기술융합의 필요성, 적용가능성, 실효성에 초점을 맞추어 고찰하였다. 가스하이드레이트 개발 사업은 지식경제부 내 가스하이드레이트 개발사업단 주관으로 2005년에 시작되었으며 2014년까지 I 지역 탐사 및 시추, II 지역 탐사 및 시추, 시험생산의 3단계의 달성목표를 가지고 있다. 가스하이드레이트는 천연가스가 저온 고압 상태에서 물과 결합해 형성된 고체 에너지로 화석연료 고갈에 따라 이를 대체할 가장 유력한 청정에너지원으로 주목받고 있다. 현재 가스하이드레이트 개발사업단에서는 지구물리탐사분야 지질지화학분야 개발생산분야로 세부 기술모듈을 형성하여 목표달성을 위해 노력하고 있지만, 중과제간 교류가 부족한 상황으로 인해 목표달성을 위한 기술력의 확보 및 향후 상업생산에 대한 불확실성이 증가하고 있는 상황이다. 이와 같은 상황을 해결하기 위해서 기술개발 및 혁신의 수단인 기술융합의 필요성이 증가하고 있다. 기술혁신은 기초연구, 응용연구, 개발, 학습, 투자 등의 일련의 과정을 거쳐 경제적 성과와 사회적 영향을 만들어내는 개념으로 정의 할 수 있다. 기술혁신을 이루어내는 가장 중심적인 역할을 담당하는 기술융합은 2개 이상의 요소기술들이 결합하여 기술이 갖지 않는 새로운 기능을 발휘하는 기술혁신의 한 현상으로 정의할 수 있다. 기술융합은 21세기 초에 접어들어 급속하게 변화하는 양상을 보이며 예상보다 경제에 더 큰 영향을 미치고 있다. 가스하이드레이트 각 단계에서의 애로점을 극복하기 위한 기술혁신을 위해 지구물리탐사 지질지화학 개발생산분야간의 융합의 가능성 등을 타진해본 결과, 각 기술융합들을 기술융합 유형에 맞춰 분류할 수 있었으며 유형별 적용가능성과 기대효과 측면에서 비교분석을 수행하였다. 분석의 정밀도를 높이기 위하여 기술융합 유형에 대한 이론과 실제 가스하이드레이트 전문가들과의 설문을 통해 비교분석을 실시하였다. 가스하이드레이트 실증 사례에 대한 분석 결과, 기술융합 이론은 기존의 큰 기술범주뿐만 아니라 작은 범주에도 적용할 수 있으며, 필요성과 적용가능성, 실효성 면에서도 충분한 고찰을 통해 기술융합 이론의 적용 범위를 좁히면 더 많은 연구와 융합기술을 얻을 수 있다는 결론을 얻을 수 있다.

New Opening of Suseo-Pyeongteak High Speed Railway (HSR) will be a new leap in the Korean railway history. However if this section of HSR line around Seoul Metropolitan Area opens, the confluence of new HSR and existing HSR line in Pyeongteak-Osong section will cause a bottle neck problem. In other words, the opening of Suseo-Pyeongteak HSR line will make the capacity of track reach the limit and the section of railroad between Pyeongteak and Osong will be saturated. This will also make such troubles as restricting the number of train which stops at Cheonan-Asan station. In this study, based on the train assignment theory of TVM430 signal system, the methods of calculating headway and number of train are reviewed and the plan for application of optimal operation pattern during peak hour between Pyeongteak-Osong section is also suggested. To remove the bottle neck problem in this HSR section, 3 alternatives are suggested and the expected effects and problems of each alternative are also analyzed. The results show that the troubles caused by excess of track capacity can be removed without any additional cost if the minimum headway in operating system for HSR is adopted in this section. In the future, if these alternatives are considered to the long-term plan for operating train and signal systems, this will improve the efficiency of train operation, which can remove the bottle neck in the HSR line.

As many companies have been interested in big data, they have invested a lot of resources to get more customer data. Some companies try to trade the data illegally. In order to collect more customer data, companies provide various incentive programs to customers. However, their results are normally much less than their expectations. This study focuses on exploring the relative importance of the factors which influence customer attitudes to providing his/her personal information. This study conducts a conjoint analysis to assess trade-offs among the five influential factors-monetary reward, concern for data collection, concern for secondary use, concern for unauthorized use, and concern for errors. This study finds that the customer attitude to providing personal information is most influenced by the concern for secondary use. Furthermore, it shows that there are some differences between the light internet user group and the heavy internet user group in the relative importances of these factors. The monetary rewards appeal to the heavy internet users, rather than the light internet users.

Recently, the importance of research and development for technological innovation is increasing. The rapid development of research and development has a number of positive effects, but at the same time there are also negative effects that accelerate crimes of information and technology leakage. In this study, a research security level measurement model was developed that can safely protect the R&D environment conducted at the organizational level in order to prepare for the increasingly serious R&D result leakage accident. First, by analyzing and synthesizing security policies related to domestic and overseas R&D, 10 research security level evaluation items (Research Security Promotion System, Research Facility and Equipment Security, Electronic Information Security, Major Research Information Security Management, Research Note Security Management, Patent/Intellectual Property Security Management, Technology Commercialization Security Management, Internal Researcher Security Management, Authorized Third Party Researcher Security Management, External Researcher Security Management) were derived through expert interviews. Next, the research security level evaluation model was designed so that the derived research security level evaluation items can be applied to the organization's research and development environment from a multidimensional perspective. Finally, the validity of the model was verified, and the level of research security was evaluated by applying a pilot target to the organizations that actually conduct R&D. The research security level evaluation model developed in this study is expected to be useful for appropriately measuring the security level of organizations and projects that are actually conducting R&D. It is believed that it will be helpful in establishing a research security system and preparing security management measures. In addition, it is expected that stable and effective results of R&D investments can be achieved by safely carrying out R&D at the project level as well as improving the security of the organization performing R&D.

In this paper, we discuss the role of allocative efficiency and X-efficiency in determining resource allocation under the share tenency. Economic efficiency of resource allocation is related to land reform. Classical and neoclassical schools insist that land reform must be achieved for agricultural development by more efficient use of inputs. According to them, there is no incentive for tenants to use inputs until $MVP{\ell}=wage$ under the share tenancy. But "equal efficiency" school's conclusions are different. They conclude that there is no productivity differences between owner cultivation and share tenancy, owing to monopoly power of landlords and/or landlords's transaction costs. Considering X-efficiency, the share tenancy is not as efficient as the owner cultivation. On the other hand, the productivity differences may be reverse, in which landlords cultivate their lands by wage contracts. Land reform--reduction of land rent or redistribution of land--will be benefitable not only for agricultural development, but also for resource allocation in farm management.
