This paper investigates the effects of public R&D support on medium-sized firms' R&D investment. The paper collects a panel dataset of Korean manufacturing firms' R&D investment and public support, and employs the DID (difference-in-differences) regression for the test of stimulating or crowding-out effect. Empirical analysis examines how the effect of public R&D support differs between small and medium-sized firms and whether firm size and technological capability moderate the effect in the sample of medium-sized firms. Empirical results show that public R&D support tends to generally stimulate private pure R&D investment for both small and medium-sized firms. Comparing the results for small and medium-sized firms, this paper finds that the stimulating effect is relatively larger and more significant for medium-sized firms, while the effect is not significant for small ones. Furthermore, the paper shows that the stimulating effect of public R&D subsidy on private R&D investment is relatively stronger for medium-sized firms with superior technological competence and the effect of tax support is greater for incompetent firms. These results suggest that public R&D policies and R&D programs, differentiated from those for existing small firms, are necessary for medium-sized firms to stimulate private R&D continuously and formulated carefully by considering firm size, technological capability and growth potential.

Studies on technological innovation of SMEs have made remarkable growth both qualitatively and quantitatively, but each study has a limitation to generalize due to lack of data, diversity of methodologies and variables. Therefore, a systematic and comprehensive statistical approach to obtain generalized conclusions through numerous empirical studies can help both the strategic decision making of SMEs and the government's innovation policies. The purpose of this study is to comprehensively analyze the technological innovation process of SMEs through meta-analysis. For this, the antecedents of technological innovation, the relationship between technological innovation and management performance of SMEs were analyzed. The results of using 62,512 samples from 111 domestic empirical studies were as follows; First, to improve the technological innovation of SMEs, internal cooperation, innovation culture, dynamic capabilities, and absorptive capacity were important antecedents. Second, in terms of IP performance, which was introduced as a proxy for technological innovation, human resource management, technological opportunities, commercialization capabilities, financial resources, and R&D expenditure. Third, technological innovation has a medium-sized effect on financial performance, however the effect of IP performance has a small effect size. Lastly, in the relationship between technological innovation and financial performance, the method of measurement and publication type showed statistically significant moderating effects.

In knowledge-based economies, the facilitation of knowledge diffusion among R&D performing actors has become the most important factor for the growth of national science and technology. Korea has strived for revitalizing R&D partnerships between public and private sectors since 1970, but results of KIS (Korean innovation survey) data analysis show that R&D cooperation with public institute or academic sector are not a great help to Korean firm's innovation on the whole. Especially, in small and medium sized firm, R&D partnerships with public sector do not have positive influence on their innovation. This implies policies of activating R&D partnership should be formulated based on firm's cooperation demand. In addition to this, discriminatory cooperation plans between large firms and small and medium sized firms are needed to raise the effectiveness of R&D partnership.

Crucial aspects to successfully realizing the re-emergence of a contemporary and sustainable supercomputing community in South Korea will involve the devoted efforts and support from key government and R&D organizations. We suggest various supplementation plans regarding the roles of support for the statutory plan. This includes the committee and the plans which are often missing necessary support systems that help competent ministries to plan properly according to the missions of the research center. This dissertation suggests that adjustment in the HPC trends will depend upon exposing and correcting problems in the law as well as overall improvement of the law. Also, the total development of a super computing market is necessary. The results of these guidelines will create a spread of demand for supercomputing for national IT resource sharing, and will foster the development of supercomputer specialists worldwide. Other major end results include significant increases in research productivity and increased rates of product development.

동사의 애매성이란 동일 동사 내부에서 공기하는 명사의 상충적 의미의 분포에 의해 발생한다. 이는 동일한 동사라 하더라도 명사의 상위개념, 흑은 개개의 명사에 따라 동사의 의미가 달라진다는 것을 의미한다. 동사의 애매성 해소를 위한 구문의미사전은 동사가 갖는 격틀과 논항에 오는 명사의 단어 집합에 의해 구성된다. 기계용 사전에서의 동사의 애매성이란 명사의 상위개념, 혹은 개개의 명사에 관한 정보가 결여될 때 나타난다. 지금까지의 구문의미사전은 개개의 동사가 갖는 격틀을 중심으로 논합명사의 예만을 제시하거나 명사의 상위개념을 기술하는 형식으로 구성되어 왔다. 이는 형식적인 패턴의 추출에는 유용하지만 대역어 선정을 위한 구문의미사전과 같은 섬세한 의미 정보를 필요로 하는 사전에서는 거의 효력을 발휘하지를 못한다. 다국어를 전제로 한 동사 대역어의 추출을 목적으로 하는 구문의미사전에서는 동사와 공기하는 논항명사의 철저한 추출과 검증에 의한 명사목록의 구축이 애매성 해소와 정확한 동사 대역어의 선정에 전제가 된다. 본 논문에서는 KAIST Corpus를 기반으로 현재 구축 중인 한국어 구문의미사전의 개요와 구축 과정에서 얻어진 방법론을 소개한다. 이 연구개발 결과는 과학기술부 KISTEP 특정연구개발과제 핵심소프트웨어개발 국어정보처리기술개발 중 "대용량 국어정보 심층 처리 및 품질 관리 기술 개발"의 지원을 받았다.

Keyword indexed in multidisciplinary journals show trends about science and technology innovation. Nature and Science were selected as multidisciplinary journals for our analysis. In order to reduce the effect of plurality of keyword, stemming algorithm were implemented. After this process, we fitted growth curve of keyword (stem) following bass model, which is a well-known model in diffusion process. Bass model is useful for expressing growth pattern by assuming innovative and imitative activities in innovation spreading. In addition, we construct keyword co-occurrence network and calculate network measures such as centrality indices and local clustering coefficient. Based on network metrics and yearly frequency of keyword, time series analysis was conducted for obtaining statistical causality between these measures. For some cases, local clustering coefficient seems to Granger-cause yearly frequency of keyword. We expect that local clustering coefficient could be a supportive indicator of emerging science and technology.

Since the year 2000, emphasis has been placed on a more strict evaluation of national academic societies and their journals, which has caused most societies to endeavour to produce higher quality journals and research. Korean Earth Science Society (KESS) should be such an exemplary model. Thus, the purpose of this study was to isolate characteristics of well-evaluated academic societies and explore the direction KESS should proceed to better its educational agents and strengthen its research contributions. Back in 2002, the Korean Research Foundation graded the journal of KESS as an officially qualified journal. It was bequeathed the first institute to be registered in the category of Earth Science. Furthermore, such classification was accepted as national academic classification and Scientific Citation Index through a public hearing executed by the Korea Institute of Science and Technology Evaluation and Planning in 2003. Currently, the Korean Research Foundation is reviewing a proposal to approve Earth Science as a unique citation index category. This proposal is quite crucial in that such an approval would be followed by increased funding and affect the future status of KESS. More support and interest from all members of KESS are required to establish the identity of Earth Science as an independent academic entity.
