The purpose of this study is to analyze the capacities of innovation in the organization, and to examine the effects of corporate entrepreneurship, R&D capability, technology commercialization capacity and technology orientation. First, the research model and hypothesis were established based on the literature research and 153 questionnaires were distributed and collected among management office workers among manufacturing workers in Kyungbuk. The results of this study confirm that the corporate entrepreneurship positively affects R&D capacity and that R&D capacity has a positive effect on technology commercialization capacity. And we confirmed the significant moderating effect of technology orientation. However, there is no mediating effect of R&D capability on the relationship between corporate entrepreneurship and technology commercialization. These findings can provide guidelines for organizational management in the cultural aspect by identifying the effects of in-house entrepreneurship and technology orientation on cultivating the innovation capacity of management office at the organizational level.

This paper analyses the effect of R&D investment on local economies. R&D investment contributes to the regional local economy by increasing employment and production activity of the investees. The investees may end up with increased productivity, sales and employment. At the regional R&D level, the central government R&D fund and firm self R&D budget will be the source of R&D investment. Further positive effects are inter-related with local industries. This study carried out an empirical analysis on the effect of R&D investment on local economies using Korean panel data after comparing international literatures. The dynamic panel estimator is used to estimate an autoregressive model with lagged dependent variable. Using the Da Silva method, mixed variance-component moving-average error process is estimated and selected. R&D investment is very important factor to improve the productivity of a region and the size of the effect is dependent on the time periods within the Korean economic history.

본고에서는 현재와 같은 자원내쇼낼리즘으로 인한 에너지 위기를 극복하고, 국내의 부존천연자원을 최대한으로 총동원하여 개발해야 한다는 필요성에 입각하여, 농촌산재의 극소수력, 풍력자원을 개발하고, 이와 아울러 저수지, 양수개발시설등을 병용함으로서 경제적이고 신뢰성있는 전력을 농촌에 공급하여 이로써 농촌의 전화, 기계화, 수리화, 치수효과를 도모하고 새마을 운동의 목적을 효과적으로 달성하도록 한다는것은 매우 바람직한 일이라 할 수 있다. 농촌전원개발은 또 과학기술의 발전과 농촌소득증대, 농촌노동력의 효과적 이용등의 견지에서 다목적의 성격을 지니고 있기 때문에 그 자원조사 및 개발을 하루 속히 실현할 것을 촉구하고 기대한다.

The purpose of this study is to investigate the effects of public R&D subsidies on private R&D. We have analyzed rationales for the public R&D subsidy from different perspectives. On the basis of literature review, a two step research model is constructed: participation phase (when firms benefit from public subsidies) and decision phase (when firms make decision on additional R&D investments). Using propensity score matching(PSM) method, we compare the potential outcome of the treated group to a matched controlled group of non-subsidized firms. The data used in this paper was collected from various sources. The Korean Innovation Survey 2008(manufacturing sector) is a main source of data. Financial data such as revenue, asset and capital stock, and number of employees were supplemented from the Nice Information Service KIS Value database. The R&D survey, conducted by MEST(Ministry of Education, Science and Technology) each year, was also used for the R&D expenditures of the manufacturing firms. This study comes up with the following empirical results. First, a firm's innovation capability, financial constraints, and sector appear to influence the selection of firms who were benefited from government's financial supports for R&D. Second, empirical results show that public R&D funding complements private investment on average and appear to have perpetual effects on the following year. Finally, sectoral difference in the effect of public subsidies on firms' R&D investment was confirmed. In addition, SMEs show more positive effects than large firms.

This study is intended to demonstrate how different factors induce the Korean government's direct investment in research and development according to the type of business enterprise in Korea. We analyzed that what factors made the government directly invest in research and development by using a total of 18,272 company panel data, which are not limited to specific industries or government-led research and development (R&D) programs. The results showed that the direct investment for R&D by the government led to the increase in the number of researchers in SMEs. For major companies, the direct investment resulted in the increase of sales and company's own R&D expenses. Moreover, this study found that government's direct support for R&D even led to the decrease of SMEs' own R&D expenses; however, this result was not statistically significant. In addition, the most significant factor to increase both SMEs' and major company's own R&D expenses was the sales amount of the company, rather than government's direct investment for R&D. The factor that increases sales was the company's own R&D expenses, rather than government's direct investment for R&D. Through the analysis using Mixed Effects Model, this study suggested the policy should be changed to make SMEs invest in its own R&D expenses, rather than to secure researchers of SMEs by government's direct investment for R&D.

This study developed a methodology for estimating the fatality reduction by introducing technical regulation on pedestrian protection in pedestrian-vehicle collisions. Modeling a probabilistic pedestrian fatality model with logistic regression approach was one of keen interests, which employed in estimating the fatality reduction. Collision speed obtained from the accident reconstruction was used in the model development. The effects of fatality reduction, in case various Head Injury Criterion (HIC) and collision speeds are applied for the regulation. were presented as the major outcome of this study. It is expected that the outcome of this study would be an invaluable tool to assist in developing various technologies and policies for pedestrian protection.

고랭지 지역 등에서 매년 집중강우로 인하여 많은 양의 토양유실이 발생되고, 이로 인한 탁수 사태가 장기화되면서 많은 환경 및 사회적 문제가 발생되고 있다. 환경부에서는 2007년 고탁수 발생지역을 비점오염원 특별 관리지역으로 지정하고 전 방위적인 비점오염 저감 노력을 수행하고 있다. 최근 환경부와 농림부에서는 농업지역의 비점오염원 저감을 위해 필지단위 BMP를 적용하고, 저감효과를 모니터링하고 있으며, 2011년도에는 BMP 적용에 따른 삭감효과를 평가할 수 있는 모델이 개발되었다. 하지만 모델을 이용하여 정확한 BMP 적용에 따른 삭감효과를 산정하기 위해서는 필지에서 발생되는 유출량 및 유사량에 대한 검보정이 수행되어야한다. 그러나 기 개발된 삭감효과 산정모델은 사용자가 유출량 및 유사량에 대한 검보정을 수동으로 실시하기 때문에 검보정 과정 중 사용자의 주관적인 경향이 모델 변수 선정에 영향을 미칠 수 있어 비효율적이다. 정확성 및 객관성을 확보한 검보정 수행을 위해서는 반드시 자동 검보정 툴 개발이 필요하다. 이에 본 연구에서는 Parasol 방법을 이용하여 삭감효과 산정모델의 자동 검보정 툴을 개발하고 적용성을 평가하였다. Parasol 방법은 최적화 및 불확실성 분석방법으로, 원격 토지 표면 모델링 토양 침식, 지하 수문학과 같은 유역 모델 보정 및 수문학의 다른 분야에서 많이 사용되고 있는 SEC-UA 알고리즘을 사용하여 매개변수들을 자동 변환하고, 목적함수로 SSQ를 이용하여 최적매개변수를 찾아낸다.
