The paper aims to establish the characteristics of the Korean firms' R&D investment and to estimate the private rate of return to R&D investment. For the empirical analysis, a balanced panel data is constructed with 695 firms on 8 year observations. The panel data enables to characterize R&D investment of the Korean firms, which is mostly conformed to the 'stylized facts' of R&D investment that found in the previous studies on foreign firms. Klette model was used to estimate the private rate of return on R&D investment and depreciation rate of R&D capital. The paper estimates that the rate of return on R&D investment is 10.5% on average or 16.4% on median for the whole industry whereas manufacturing firms show 10.4% on average or 16.4% on median. The depreciation rate was estimated about 32.9% for whole industry, where it ranges from the minimum 11.6% for metal industry and 49.5% for services. The median estimate of the rate of return for R&D investment of Korean firms is roughly two times higher than real interest rates for the same period, which implies that R&D investment allows sizable rent in addition to the opportunity cost of capital investment.

This paper aims at analyzing the use of REITs for developing student housing. To do this, firstly, the case studies of student housing REITs in U.S. are analyzed, and secondly, possibility and schemes of using REITs in Korea for the expansion of student housing. REITs are actively participated in the investment and management of student housing in U.S. and they are vertically integrated real estate investment operating companies which play a role of design-development-investment-managementconsulting. Student housing REITs can be fully used in Korea. To do this, special strategy integrating investment and management strategy should be examined. In these context, joint-venture model and PPP-conbined model are suggested to use REITs effectively.

The purpose of this paper is to give policy implications for relevant policy-makers by analyzing factors affecting performance of industrial R&D programs of the Ministry of Knowledge Economy. The independent variables are type of project leader organization(Big Enterprises, SMEs, Ventures Businesses, Public Research Institutions, Universities), cooperative or noncooperative R&D among industry-university-research institution, total number of project participant organization, total R&D investment, and the ratio of private investment to total R&D investment. The dependent variables are domestic or foreign patents granted and domestic or foreign papers accepted. The method of analysis is Poisson Regression analysis operated by STATA. The results of this research are follows ; Universities show higher R&D performance compared to enterprises or public research institutions in terms of patents and papers as well. Venture businesses show higher patent performance compared to SMEs. Inverted U-shaped relationship between total number of project participant organization and R&D performance is not supported. The higher total R&D investment, the higher R&D performance. The higher the ratio of private investment to total R&D investment, the higher R&D performance.

Recently, the government is very active to secure the financial resources by inducement of the private investment in fulfilling an extension of the SOC facilities. One of the reasons that the private investors hesitate to put money into the private finance projects, however, is the lack of knowledges about various risks to be possibly incurred during the project execution. This research was performed as one of the preparation works in order for a A engineering company to act as a prime contractor of the project management service in the private finance project, and finally developed the risk factor dictionary as a new concept to satisfy the requirement of a A company and overcome a limit of the existing risk checklists. Although the risk factor dictionary looks like the only simplified table to be the risk factors identified in three dimensions, the impacts and response strategies expressed in narrative and multi-items, and the responsible parties indicated, it has great meanings to get a lot of direct and indirect accomplishments over the simplified table during the development process.

미국의 ASC(American Superconductor Corp.)에서는 산화물계의 고온초전도선재를 대량생산하기 위한 대규모 투자를 계획하고 있으며 지금은 금속계 초전도선재처럼 장척의 고온초전도선재도 구매할 수 있는 시대로 접어들고 있다. 고온초전도체 벌크 및 박막의 경우도 새로운 프로세스들이 계속 시도되고 최적화 연구가 성과를 거두면서 고성능, 고품질의 재료들이 제조되고 있고 이것들을 이용한 상용화 연구개발이 미국, 일본을 중심으로 활발하게 이루어지고 있다. 최근 5년간의 고온초전도 분야에 대한 미국 연방정부의 연구비 투자 상황을 살펴보면 계속 증가추세에 있으며 벤처 비지니스의 민간기업들이 고온초전도체를 상용화하기 위한 많은 투자와 노력을 하고 있다. 고온초전도체는 그 사용 용도에 따라 벌크, 박막, 선재 등 다양한 형태로 만들어지고 있다. 본 고에서는 고온초전도체의 여러 연구분야 중 이론, 물성보다는 주로 응용기술적인 차원에서 재료 형태별로 최근의 연구개발 동향을 살펴보고자 한다.

The purpose of this study is to suggest a systematic procedural model for selecting competent project promoter. The proposed model was made by comparing domestic regulations and procedures with foreign nations', and through interviews with experts and literatures survey. The summaries of this paper are as follows. The current promoter selection procedure was evaluated by reviewing relevant papers, regulations and existing model. Some obstructions which hinder PPI project activation were identified, those are inadequacy of promoter qualification and negotiation process, lack of communication between parties, etc. Some alternatives which remove major obstructions are embodied in the model. The suggested model is comprised of PQ(prequalification), two phased evaluation for the technical proposals which include alternate, communication meeting, etc. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended. They will participate in each evaluation stage with full activities, and provide government with some technical materials for selecting promoter as coordinator.

As the national competitive power indicator, the infrastructures have been constructed with government's SOC budgets. However, even SOC budget is decreased, Public-Private Partnership Project (PPP project) has been introduced to solve demands on extending infrastructures, and among PPP projects, road projects take high portions. This study analyzes the operation & management item of financial model which is connected to the O&M cost and project proposal of previously proposed road project and analyzes the Korea Expressway Co.,'s project cost items and O&M tasks to reflect the characteristics of road projects. Based on results, this study suggests necessity of the O&M cost breakdown structure and the cost calculation standard on each cost item. Also, for the existing task execution tools, O&M cost calculation tool and finance analysis task tool will be integrated, and the system is suggested web-based system. Thus, it is expected that it contributes to the securing overall business values on PPP project and expending profit-base infrastructures.

This study is about the demand survey of R&D for preventing disaster and safety accidents. The results are as follows. First, the priorities of technology development is shown in the following order: natural disasters, human and social disaster, and safety accidents. Second, the amount of R&D investment is shown in the following order in respect of disaster management phase: prevention, preparedness, response and recovery. However, investment in the recovery phase was low. Third, it was concentrated on some types the demands of technological development in the public sector. There is a possibility of duplication of technology development in government investment. Suggest that interagency cooperation is required.

WTO 체제의 등장과 기술경쟁의 가속화로 기술의 확보가 기업경쟁력의 핵심으로 등장하고 있는데, 우리나라 정보통신 산업의 경우 민간부문의 기술개발 활동은 그 투자면에서 뿐 아니라 기술관리 측면에서도 취약성을 면치 못하고 있다. 이에 우리나라 정보통신산업체를 대상으로 연구개발전략의 실태를 조사하여 그 문제점과 개선대안을 탐색한다. 실태조사 결과 정보통신산업체들의 연구개발전략은 아직 전사적 차원의 "Total R&D"개념이 다소 부족하고 장기적인 관점에서의 연구개발 활동이 미흡한 것으로 나타나, 중장기기술개발계획과 연계된 전략적 연구관리체제의 도입이 필수적이다.

본 연구는 IT 기업의 R&D활동의 성과를 파악하는 것을 목적으로 한다. 공공 R&D의 성과에 대한 연구는 상당부분 진척이 이루어졌으나, 경제의 주체인 민간기업의 R&D 활동에 대한 연구는 부족한 실정이다. 이 연구목적을 위하여, 기업의 재무자료를 이용하여 R&D투자액을 집계하였으며, IT기업의 경영성과도 분석하였다. 분석한 결과를 간단하게 요약하면, 다음과 같다. 첫째, IT기업은 대기업의 R&D투자 비중이 $93.6\%$에 달한다. IT R&D 투자 상위 10개 기업이 IT 산업에서 매출액의 $71\%$, 종업원의 $61\%,$ R&D 투자의 $87\%$를 차지한다. 둘째, 기업의 투자활동은 선택과 집중의 원칙에 따라 R&D 투자에 주력하는 경향이 강해졌다. 유형자산투자는 급격한 감소를 보이는 반면, R&D투자는 증가하고 있다. 셋째, IT 중소기업의 R&D투자는 한계가 있을 수밖에 없다. 본 연구에서 나타난 분석결과의 시사점을 보면, IT 중소기업의 R&D 투자는 한계가 있을 수밖에 없다. 따라서 중소기업의 R&D투자의 효율성을 높여주는 한편, 미래성장의 seed에 대한 준비와 단기 개발연구를 통해 기업의 수익에 기여할 수 있도록 해야 할 것이다. 또한 IT 대기업과 중소기업의 R&D에 대한 효율적인 네트워크를 구축하는 것도 IT기업의 활성화를 위해 요구된다.
