This paper looks at "network" aspects of research and development (R'||'&'||'D) with a special focus on small and medium (S'||'&'||'M) automotive part makers in Korea. It throws light on recent changes in the technological capability building mechanism of Korean automotive firms. The Korean automotive firms have mostly built up technological capability from scratch. It is widely acknowledged that they have benefited from two cooperative relations: namely (1) the close cooperative relationship with their own assemblers and (2) technical assistance from auto parts makers abroad. Too much emphasis on these two links can, however, keep us from understanding new developments. This paper argues that auto parts firms have diversified their networks for technological development. It is based on the analysis of the data drawn from the survey on technological development activities of small and medium sized firms, which was carried out by the Korea Federation of Small and Medium Business. Many automotive firms have recently increased joint R'||'&'||'D links with university and/or research institution while their reliance on foreign sources have decreased.

This paper discusses the economics of local loop architecture focusing on existing technologies, ADSL, HFC, and new one, PLC, and suggests a new modeling approach of access network system and the numerical equations. To modelize access network system and drive the numerical equations, we consider the double star and the tree & branch architecture and made block diagram of each access system. In addition, we introduce the density of subscriber as a variable and the equation of seeking the optimal number of cell in a service area. The economics of local loop architecture is analyzed in two ways, i.e. with and without consideration of the cost of cable and infrastructure. From the numerical analysis, we find that in case of not including the cost of cable and infrastructure, there is no much difference in the cost per one subscriber, while, in case of including it, there is remarkable difference among technologies. Therefore we conclude that the economics of local loop architecture is depend on the density of subscriber and existing network infrastructures.

혁신클러스터는 전 세계적으로 지역의 경쟁력을 높이는 주요 도구로 활용되고 있다. 한국도 정책적으로 다양한 형태의 혁신클러스터를 조성 및 육성하고 있다. 하지만 성공적인 혁신클러스터 육성을 위한 체계적인 분석은 활발하지 않은 실정이다. 본 연구에서는 문헌연구를 통해 혁신클러스터의 성공요인을 도출하고, 이를 활용하여 분석을 위한 프레임워크를 제시하였다. 또한 제시한 프레임워크에 따라 판교테크노밸리를 대상으로 사례연구를 하였다. 분석 결과 성공적인 혁신클러스터를 위해서는 혁신지향적인 환경, 지속적인 정책적 지원, 지식 네트워크의 활성화, 혁신성과의 환류가 중요한 것으로 나타났다.

Since the early 1990s, cluster-based policies have been celebrated as the basis of successful regional industrial and technological development strategy by encouraging regional innovation and technological spillover. Most recently, the Korean government has also begun to seek to initiate some strategies for promoting industry clusters. However, it is problematic that the cluster policies still focus on attracting related firms and establishing supporting agencies and physical infrastructures rather than improving social and institutional dimensions for cluster development such as social capital, networks, social learning capabilities, the governance of regional innovation. In this paper we attempt to elucidate social and institutional dimensions for cluster development and suggest some policy agenda to promote innovative cluster.

비즈니스 모델 혁신이란 비즈니스 모델을 구성하는 여러 가지 요소를 다각도에서 변형시켜 차별화되는 가치를 창출해내는 것으로 기업의 외부 환경이나 내부 환경 중 어느 한 쪽에 집중하기 보다는 내부의 자원과 역량, 그리고 외부 환경이 만나는 곳에서 최적의 선택을 하는 것이다. 그러나 비즈니스 모델 혁신에 대한 명확한 정의가 없고, 핵심 비즈니스 모델을 잘 활용하지 못하는 관계로 기업이 비즈니스 모델 혁신을 통해 성장한다는 것은 매우 어려운 일이다. 본 논문에서는 비즈니스 모델 혁신에 대한 정의를 체계적으로 정리하고, 비즈니스 모델 혁신이 필요한 시기가 언제인지, 어떠한 유형의 비즈니스 모델 혁신이 있는지를 몇 가지 사례를 통해 살펴보았다. 기업의 가치 제안, 가치사슬과 가치네트워크를 통한 가치 창출과 수익모델의 혁신 사례를 통해 비즈니스 모델 혁신이라는 다소 추상적인 개념을 좀 더 친숙하게 접근하였다. 마지막으로, 이미 성공한 기업 역시 비즈니스모델 혁신과 적응우위 강화로 급변하는 시장 환경에서 새로운 가치를 창출할 수 있음을 사례분석을 통해 입증하였다.

본 연구에서는 자기조직화 교사학습 신경망인 SOSL(Self-Organized Superised Learning)과 이 신경망의 구조를 제안한다. SOSL신경망은 하이브리드 형태의 신경망으로써 다수 개의 컴포넌트 에러 역전파 신경망들과 수정된 PCA신경망으로 구성된다. CBP신경망은 군집화되고 복잡한 입력패턴에 대하여 교사학습을 병렬적으로 수행한다. 수정된 PCA신경망은 군집화 및 지역투영에 의하여 원 입력패턴을 보다 작은 차원으로 변환시키기 위하여 사용된다. 제안된 SOSL은 많은 입력패턴을 가짐으로써 큰 네트워크 크기를 가지게 되는 신경망에 효과적으로 적용이 가능하다.

Due to the drastic technological innovation and introduction of various kinds, of new communication services, the structure and operation of communication networks are becoming complicated and diversified more and more. Accordingly, the necessity of flexible simulation tools which can be utilized for various performance evaluation jobs in various types of communication networks is growing. In this article, various existing simulation tools are briefly surveyed and the requirements for the simulator dedicated for the performance evaluation of communication networks are discussed. Then, a strategy to develop a simulator dedicated for the performance evaluation of communication networks is proposed. Our approach is based on the prototyping strategy, in which a relatively simple prototype structure is developed first and more functions are added whenever necessary. By following this strategy, a simulator can be developed and evolved in a timely manner at a relatively small cost.

In the knowledge-based society of the new millenium, major countries have implemented computer literacy. Recently the Korean government announced 'CyberKorea21'and established 5 year information & communication technology development plan. In Canada, project CANARIE represents a contribution to building the communications infrastructure of the high-speed communications networks of the 21st century. Countries around the world are looking to Canada as the model for Internet research network(Ca*net3) and 'connecting Canadian'. The purpose of this paper is on the strategic implications through comparative analysis of computer literacy between Canada and Korea.

This paper describes the evolutionary trajectory of the missions of public research institutes(PRIs) in Korea since 1960s and analyses the newly highlighted role of PRIs as the facilitators of regional innovation system, with questionnaire surveys and the case study of Gwangju Institute of Science and Technology(GIST). PRIs have played important roles in Korean rapid economic development by introducing and improving foreign high-technologies in 1970s and 1980s and by creating new advanced high-technologies in 1990s. In recent years, the functions as regional technology innovators have been considered important as regional innovation system has come to the center of discussion. According to the result of this study, Korean PRIs have recognized their roles relevant to regional innovation, such as developing the technologies of regional strategic industries and awakening regional innovative actors to a sense of research. Regardless of the functions as industrial technology suppliers, however, the bilateral networks between PRIs and regional industries are not revealed strong, whereas those with universities and other research institutes are relatively strong. In addition, the research cooperation of PRIs with regional innovative actors are different by where they are located. The case of GIST shows how a regional PRI operates, commercializes its academic achievement and encourages the regional transfer of the achievement systematically. Finally, this study draws some policy implications on developing regional PRIs.

The aim of this paper is to identify the characteristics of social economy in social farming practices, and to explore three core factors of experiment, openness and locality, which have a significant impact on the working-mechanism of social innovation. Though a few social farming practice appear nowadays in Korea, it can be witnessed social economic factors such as cooperation between networks and solidarity actors, pursuing social values in social farming. On the basis of the conceptual framework on the social economy characteristics, this study examines case analysis in order to find the possibilities as a social innovation of the social farming. Three farms perform multiple functions of care, labour integration, training in farming area, and sometimes make collaboration work with artists and local residents. Social farming can be social innovation practices in the view of the interaction of experiments, openness and locality within the context of an innovation process, networking, enhancing social capital.
