In order to performing the joint operation of Korean army efficiently, informations about surveillance, reconnaissance, and situation awareness need to be possessed jointly. In the first development phase (basis type) of the Korean joint tactical data link system (JTDLS-K), essential tactical information and recognized situation are owned among platforms in common by using existing wireless terminals. In the second development phase (completion type) of the JTDLS-K, a JTDLS which can perform network centric warfare (NCW) will be developed in due consideration of technology development of the basis type and common technology maturity degree. This is a joint battlefield system that can show fighting power simultaneous and polysynthetically through providing command and control messages effectively to each platform, which is participating in the joint and combined operations. In this paper, the development of JTDLS-K with a common data processor based on common link integration processing (CLIP) is described. From the test results of the system presented in this paper, it is demonstrated that quadrature phase shift keying (QPSK) signals can be applied to the system.

현행 민영화정책이 공기업의 효율성제고를 최우선 목표로 설정한 것은 타당한 선택이었음에도 불구하고, 경제력집중 심화에 대한 우려와 주식시장의 제약 등을 이유로 민영화정책은 그 추진실적이 부진하고 향후 지속 여부가 불투명한 것이 현실이다. 본(本) 논문(論文)은 우리나라 공기업민영화를 둘러싼 논쟁의 핵심인 경제력집중(經齊力集中), 경쟁도입(競爭導入), 주식시장여건(株式市場與件) 등이 공기업민영화와 관련하여 어떻게 이해되어야 할 것이며, 바람직한 정책대응(政策對應)은 무엇인지를 논의하고 있다. 재산권이론(財産權理論)을 동원하여 주인(主人) 있는 경영(經營)의 의미를 재해석할 때, 기업지배(企業支配) 통제구조(統制構造)의 정착이 요원한 우리 현실에서 민영화가 기업효율을 제고하려면 민간대주주(民間大株主)의 지배(支配)를 인정하는 방식이 최선책(最善策)이며, 소유가 분산되고 전문경영체제(專門經營體制)를 도입하는 민영화방식은 지배구조(支配構造)의 실패가능성(失敗可能性) 때문에 차선책(次善策)이라고 평가된다. 그러나 효율성 차원의 최선책은 경제력집중이라는 국민경제적 비용을 초래하므로, 정부로서는 경제력 집중이라는 비용(費用)과 효율성이라는 편익(便益)을 조화시키는 방안을 모색할 수밖에 없다. 이 경우 정부가 고려할 보완책(補完策)으로는 감자후(減資後) 민영화(民營化)와 분할민영화(分割民營化)가 있다. 한편 자연독점의 특성이 뚜렷한 일부 네트워크사업분야를 제외하면, 민영화시 경쟁도입(競爭導入)은 기업효율성과 국민경제의 배분효율성을 제고하므로 정부로서는 당연한 선택일 것이다. 경쟁은 공기업의 인수자격규제에 있어서도 새로운 기준을 제시하는데, 민영화를 정부(政府)와 민간(民間)사이의 M&A로 이해하고 경쟁제한적(競爭制限的) 기업결합(企業結合)을 규제하는 공정거래법(公正去來法)의 정신(精神)이 인수자격규제기준이 되어야 하며, 업종전문화(業種專門化) 발상(發想)에 근거한 인수자격규제는 득보(得)다 실(失)이 클 것이다. 아직도 자생적 성장기반이 취약한 주식시장의 제약에 따라 민영화일정의 탄력적인 조정은 불가피하지만, 정부는 상장(上場)의 필요성(必要性)을 재검토하고, 매각(賣却)의 우선순위(優先順位)를 조정하며, 무엇보다도 양질(良質)의 주식(柱式) 공급(供給)이 수요(需要)를 창출하는 메커니즘을 개발해야한다. 이와 함께 본(本) 논문(論文)은 현행 추진체계(推進體系)에 내재된 민영화의 지연가능성이 심각한 문제임을 지적하였고, 대규모 공기업의 민영화가 대기업(大企業)의 새로운 전형(典型)을 창출하여 한국자본주의(韓國資本主義)의 건전한 발전을 앞당기는 역사적 기회라는 점을 강조하고 있다. 마지막으로 재벌인수가 가능한 경우와 규제되어야 할 각각의 경우에 대하여 민영화정책(民營化政策)의 '체크리스트'를 제시하고 있다.

This paper is to conceptualize 'new urbanization' on the basis of a certain possibility of 'sustainable urbanization' in the capitalist society, while admitting some criticism on its possibility. For this purpose, first of all, this paper points out some economic and environmental difficulties in the Fordist regime of accumulation and the developmentalist strategies which have promoted the modem urbanization in the industrial society. Then, this paper examines the concept of 'sustainable development' which has been suggested to manage such problems in modem industrial cities, and explores its limitation that the application of this concept has been usually confined to some ex post facto - that is, weak sustainable development - strategies to resolve urban environmental problems. Finally, in order to overcome these problems both of developmentalism and of weak sustainable development, this paper conceptualize strong sustainable development for new urbanization and suggest urban environmental strategies for strong sustainable cities.

This paper presents the algorithm using fuzzy inference that preestimates each link speed changed by different kinds of road situations. The elements we are considered are time zone, rainfall probability information and lane control information. This paper is consists of three parts. First of all we set up the fuzzy variables, and preestimate link speed changed by various road situations. For this process, we build the membership functions for each fuzzy variable and establish the fuzzy inference relations to find how fuzzy variables influence on link speed. Second, using backtracking method, we search the shortest route influenced by link speed changed by fuzzy inference. Third, we apply this algorithm to hypothetical network and find the shortest path. As a result, it is shown that this algorithm choose appropriate roundabout path according to the changing road situations.

Implementation of DPI(Deep Packet Inspection) system on a general purpose multiprocessor platform is an attractive option from the implementation cost point of view, since it does not require high-cost customized hardware. Load balancing has been considered as a primary means to achieve high performance in multi processor systems. We claim, however, that in case of DPI system design simply balancing the load of each processor does not necessarily yield the highest system performance. Instead, we propose a method in which tasks are allocated to processors based on their functions. We implemented the proposed method in dual processor Linux system and compare its performance with the existing load balancing methods. Under the proposed method, one processor is dedicated to deal with interrupt handling and generic packet processing, while another processor is dedicated to DPI processing. According to experimental results, the proposed scheme outperforms the existing schemes by 60%, mainly because of the reduction of cache miss and spin lock occurrences.

This study illustrates and compares the platform strategy of Apple and Samsung, which have been operating their own App stores, by using the $IISI^n$ model. Apple, the first mover of the platform, has employed closed strategy for quality control of the platform and customer loyalty. On the other hand, Samsung has employed open strategy for increasing the platform network effects. The result of this study showed that the platform strategy "Openness", which is a free entry of participants, and "Sharing" of created value, are important along with the excellent platform environment. As a pioneering study of the platform strategy for the co-creation, this research contributes to both theory and practice.

Technology innovation is a competitive weapon of sustainable economic growth at the urban and regional level and the growth of firms. In this study, we empirically investigate the effects of collaborative R&D activity on product innovative outputs and process innovative outputs in manufacturing firms in Korea. We analyze the links between collaborative R&D activity and two types of innovative outputs using an alternative negative binomial regression model. The major finding is that collaborative R&D activity has significant positive effects on both product and process innovation. The results also identify a positive link between all types of innovative outputs and other R&D activities including internal R&D activity, patent activity, external technology and capital goods acquisitions. To induce corporate growth that enhances the productivity of individual firms and produces prolonged economic growth, policy makers should place greater emphasis on creating effective arrangements to promote establishing collaborative R&D strategies for manufacturing firms.
