This study aims to identify the causal relationship among public technology transfer, technological performance, and research and development (R&D) productivity. Using the impulse-response function(IRF) of a panel vector autoregressive model (panel VAR), this study suggests the results of how long the factors such as technological performance (patent), public technology transfer, and R&D productivity takes and lasts if a one-unit shock of standard deviation occurs. As a result, first, the increase of public technology transfer activities has no power to increase the technology performance but improve the R&D productivity. If the public institute increases its technology transfer activities by one unit, the R&D productivity will increase within five years. Second, the impact of increasing technological performance on improvement of public technology transfer and R&D productivity is an insignificant. Third, the effect of R&D productivity on the public technology transfer creates a substantial reaction after a current time. Considering the structural relationships among public technology transfer, technological performance, and R&D productivity, if policy makers intend to construct the active R&D circumstance, technology suppliers should be motivated to run the active R&D mechanism because they achieve gains.

We investigate the effect of government and public sector R&D Investment at IT Industry on the amount of Production, export and nongovernment R&D Investment at IT Industry. We, firstly, examine the stationarity of each variable by the unit root t-test and perform the co-integration test for the pairs of variables. We use YECM(Vector Error Correction Model) according to the results of co-integration test for the examination of Granger-causality between variables. It is found that there exist an Granger-causality between public sector R&D Investment and nongovernment R&D investment and also between public sector R&D Investment and export. Secondly, we analyze the impulse response of government and public sector R&D Investment at IT Industry on the amount of production, export and nongovernment R&D investment at IT Industry based on VECM model. It is found that the response of the amount of production is highest at 3th period and is lowest at 8th period and that of export shows similar pattern.

The importance of intangible assets have increased unprecedentedly with the advent of the knowledge-based society. Investment in R&D has contributed to the rise of productivity and firm-value in the capital markets. but it is very difficult to determine the economic benefits of R&D investment, due to elusive link between time requirements and the realization of firm value from R&D investment. This study examines the differential effects of R&D expenditure and patents on firm-value by industry. Patents are intangible, proprietary rights that develops new products, plays a crucial role in market competition and results in research and development activities. If firms get patents, their R&D expenditure is assumed to be successful. The study analyzes whether successful R&D expenditure has a significant effect on the firm-value. The study considers two industries : high-tech industries and low-tech industries. These industries are expected to have different effect on R&D expenditure and firm-vale. The results of the study indicate that the successful R&D expenditure increased the firm-value. Successful R&D expenditure in high-tech industries more increased the firm-value more than that in low-tech industries.

4차 산업혁명의 도래와 함께 급변하는 환경에 대응하기 위한 기업의 적극적인 연구개발(R&D) 투자의 중요성은 한층 더 강조되고 있다. 하지만 대리인이론의 주장에 따르면 성과창출을 위해 오랜 기간이 요구되고 마케팅, 공정개선 등의 다른 투자들과 비교할 때 상대적으로 높은 실패 위험을 내포하는 특성으로 인하여 경영자들은 R&D 투자를 소홀히 하는 경향을 나타내기 쉽다. 이를 극복하기 위해 R&D 투자에 대한 의사결정에 영향을 미칠 수 있는 조직과 개인 수준의 다차원적 요소들의 영향을 파악하고, 이를 적극적으로 기업운영에 반영하는 것이 지속가능한 경쟁우위 창출을 위한 핵심과제로 부각되고 있다. 하지만 어떠한 요소들이 이 같은 전략적 의사결정에 영향을 미치는지에 대한 선행연구는 매우 미흡한 실정이다. 따라서 본 연구에서는 기업의 과거 성과창출 방식의 경로 의존적 영향과 경영자 개인 수준의 지배적 논리가 R&D 투자에 대한 의사결정에 중대한 영향을 미치는 핵심요소들이 될 수 있다는 이론적 주장에 근거하여, 기업가 지향성이 기업의 과거 혁신성과와 R&D 투자 간의 관계를 부분 매개하는 연구모형을 제시하고, 이를 242개 국내 제조업과 서비스 기업들을 대상으로 한 실증연구를 통해 검증하였다. 분석결과에 따르면 연구 모델과 가설들에서 예상했던 바와 같이 국내 기업들의 과거 혁신성과는 R&D 투자에 직접적인 정의 영향을 미치는 것으로 나타났다. 또한 기업가 지향성은 혁신성과와 R&D 투자의 관계를 부분 매개하는 것으로 나타났는데, 이는 기업의 과거 성과가 경영자 개인 수준의 지배적 논리를 강화하고, 이는 다시 기업의 의사결정에 영향을 미칠 수 있다는 주장을 뒷받침하는 실증적 분석결과이다. 과거 혁신성과가 기업의 경로의존성에 의해 미래의 혁신전략에 영향을 미칠 수 있고, 이 같은 관계가 경영자의 지배적 논리를 통해 영향 받을 수 있다는 본 연구의 분석결과는 기업들이 환경변화에 부합하는 충분한 R&D투자를 이끌어내기 위하여 경영자의 지배적 논리라는 개인수준의 요소와 기업의 과거성과라는 조직수준의 요소를 조화롭게 활용해야 한다는 사실을 시사하고 있다.

Unmanned Aerial Vehicles (i.e., drone) are gaining a lot of interest from a wide range of application domains such as infrastructure monitoring and parcel delivery service. In those service scenarios, multiple UAVs are involved and should be reliably operated by so-called UAV management system. For that, we propose oneM2M standard based UAV management and control system which is specifically targeted at traffic management of low-altitude UAVs. In this paper, we include oneM2M platform architecture and its implementation for UAV management system in conjunction with UAV interworking procedure.

This paper presents a R&D investment model for the Information and telecommunications(l&T) technology using multiple objective linear programming(MOLP). The MOLP model involves the simultaneous maximization of three linear objective functions associated with three criteria, which are social, technological, and economic criterion. This model is different from the traditional one which only involves the maximization of economic criterion. It yields a suitable R&D investment ratio to each technology field. Its application to the National R&D Project in l&t Industry is also presented. In this application, the Analytic Hierarchy Process(AHP) is proposed to estimate the weights, which used as the coefficients in each objective function of the MOLP model. Then the problem is solved using the interactive method STEM. It is showed that with the aid of STEM, the MOLP model can be useful decision aid in formulation R&D investment plan in l&t industry. It is expected that the MOLP model works as the basis for planning R&D investment strategy in l&T industry.

The purpose of this study is to develop Meta Evaluation Indicators for Defense R&D Programs in Korea. At first, the four components of this meta evaluation model were designed, which are evaluation context, evaluation input, evaluation process and evaluation outcome. And fifty two indicators for this meta evaluation were developed by experts who performed evaluations for Defense R&D Programs. The reliability of components and items was verified by Cronbach's ${\alpha}$ coefficient. It was over 0.6 in all areas. The validity of components and items was verified by Factor Analysis. Analytic Hierarchy Process method was used in assigning the evaluation weight. The survey of twenty two evaluators participated in Defense R&D Programs showed that the Consistency Ratio was under 0.1 in evaluation components and items. In this study, an objective and reasonable set of Defense R&D Meta Evaluation Indicators was developed to increase the responsibility of Defense R&D Programs and improve the quality of evaluation results.
