  • 최근 무선 통신 기술의 발전에 힘입어 Software D Defined Radio(SDR) 기술을 적용한 유연성이 높 은 다기능 군용 통신 시스템의 구현이 이루어지고 있다. SDR 기술은 기존의 항공기, 차량에서 사용 하던 다양한 방식의 통신 시스템과의 연동을 가능 하게 하고. 미래의 시스댐에 대응하는 군용 통신 시스댐의 구현에 있어 큰 역할을 수행하게 되리라 예측된다. 이에 본 고에서는 군사통신 시스댐을 위 한 SDR 연구로 꼽히는 미 공군의 SPEAKeasy와 D DARPA의 GloMo 프로젝트에 관하여 알아보고 향 후 발전 방향을 가늠해 본다.

  • 현재 많은 기업이나 조직이 전사아키텍처(이하 EA)기반에서 어플리케이션 시스템(이하 응용시스템)을 구축 및 운영하고 있으나 응용시스템 개발 단계에서 EA관점의 응용시스템 아키텍처(응용아키텍처)를 충분히 고려하는 경우는 드물었다. 본 논문에서는 EA관점의 응용시스템 구축을 효과적으로 수행하기 위해서 프로젝트 내 어플리케이션 아키텍트(이하 AA)의 주요업무를 정의하고 조직의 EA를 만족할 수 있는 수행방법을 도출하였다. 소프트웨어 아키텍트(이하 SA)와 AA의 수행업무를 고찰하여 효과적인 프로젝트 수행을 위한 조직구성을 정의하고 AA의 수행업무 중 EA와 밀접한 관련이 있는 업무에 대해 수행 방법을 연구하였다. 또한 EA 응용레벨 별 산출물과 소프트웨어 아키텍처 정의서와의 일관성을 유지할 수 있는 방안을 도출하였다.

  • Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

  • Virtual project organization may be recognized as one of the promising business models in which many knowledge sources externalize through cross boundaries of knowledge-based organizations. This paper proposes a knowledge competence evaluation of virtual project organization based on the following perspectives: 1) Individual knowledge perspective, 2) Activity-oriented knowledge perspective, and 3) Knowledge-driven social network perspective. In the framework, individual knowledge competence having experienced or learned from knowledge-based activities and virtual networks in the project, should be evaluated according to the assumption that knowledge and collaboration competence depends on the activities and networks acquired proportionally by the past participation to projects. An illustrative SI example is given in order to validate the proposed evaluation and computing procedure.

  • Community-based disaster preparedness approaches are increasingly important elements of vulnerability reduction and disaster strategies. They are associated with a policy trend that values the knowledge and capacities of local people. In this research, we describe the community diagnosis method and develop Flood Disaster Risk Reduction Index(FDRRI) for assessment of flood vulnerability. FDRRI is composed of four indicators such as Flood Exposure Indicator(FEI), Sensitivity Indicator(SI), Risk Reduction Indicator(RRI), and Community Preparedness Indicator(CPI). We anticipate to present the guideline for selection national preparedness projects and uplift community's preparedness capacity.

  • 본 연구는 2014년 부산지역에서 발생한 집중호우에 따른 피해상황을 읍 면 동 단위의 행정구역에 대해 조사하고, 각 행정구역별 수해복구사업의 우선순위를 결정 할 수 있는 방법을 모색하는 것을 목표로 한다. 피해현황은 인명피해(사망, 이재민 수), 건물 및 선박, 농경지 침수에 의한 피해, 공공시설물에 대한 피해를 조사하였다. 또한 피해 요인별 피해액을 집계하여 수해복구사업의 평가기준으로 이용하였다. 사업의 경제성은 B/C분석 결과를 통해 반영하였다. 각 행정구역에 대한 우선순위는 다기준분석 중 PROMETHEE, ELECTRE 방법으로 분석하였고 표준화 방식은 T-Score방식을, 가중치는 엔트로피 방식으로 결정하여 분석에 반영하였다. 본 연구에서는 실제 발생한 호우에 대한 피해복구사업에 적용하여 검증을 시도하였으나, 향후 치수사업의 다양한 대안을 선정하고 우선순위를 결정하여 실제 도시개발 및 정비 사업 등으로 분야를 확장할 수 있을 것으로 기대한다.

  • Since the concept of software engineering was first used in 1968 by NATO Science Committee, a lot of research work and improvements have been made on software development methodology and software quality control, but they still fall short of ensuring successful development of small and medium scale software systems. Under these circumstances, Center for Software Engineering (CSE) at National IT Industry Promotion Agency(NIPA) has been conducting studies on quality control methodologies of software visualization well-suited for small and medium scale software systems, and also working on the systemization and quantification of software quality control. In this paper, we attempt to scope on the software development management of domestic and foreign small and medium-sized enterprises that are lying in the blind spot, compared to large enterprises with well-organized software development systems. In particular, based on software visualization that CSE is pursuing for small and medium-sized developers, we propose a practical quality control methodology well-suited for small and medium scale projects, and a low-cost quality control management tool by combining open-source quality control tools. Our proposal is expected to induce developers' mind change in SI-specialized small and medium-sized software enterprises, increase their profits and improve customer satisfaction through project quality control.

  • Forests are being seriously fragmented as a result of land development. Land development with disregard to its subsequent environmental impacts is a primary threat to biodiversity by incurring massive habitat losses and changes in structure and composition of forests. The purpose of this study was to develop the impact assessment model for quantitative distance or degree of disturbance by land developments. This study conducted a survey about structure and composition of forest species to determine degree of impact from land development. The edge effect of forest fragmentation on the number of bird species, population size, and bird diversity was obvious. In particular, the bird diversity sharply declines around the forest edge where intensive land development projects take place. To assess the disturbance of forest species, the factors selected were the bird diversity and the rate of edge species. The impact assessment model about bird diversity was explained by type of forest fragmentation and type of vegetation ($R^2$=0.23, p<0.005). The other model about edge species explained by a distance, type of forest fragmentation, type of vegetation, and width of road ($R^2$=0.34, p<0.001). In order to test the applicability of the model developed in this study, the models was applied to the Samsong housing development in Goyang-si, Gyunggi-do. The impacts of land development on the bird species were reasonably quantified to suggest effective mitigation measure. The impact assessment model developed in this study is useful to assess the magnitude of disturbance of bird species. Particularly, the model could be applied to the current Environmental Impact Assessment practices to predict and quantify the impacts of land developments projects on forest bird species.

  • In the 21th century, many people predict the change of agricultural conditions in our country because of the arrival of knowledge- information age. Now it is supposed that agricultural technology comes to $45%{\sim}50%$ level compare to advanced countries. So the development of new technology in agriculture are demanded all the more. Agriculture in the 21th century will be grown based on the connection of environment, knowledge and taffeta. The agricultural conditions in Kyongbuk has more profitablity and potentiality, because there are wide lands, distinguished 4 seasons, various main production crops and cultural inheritance etc. For the innovation of agricultural technology in Kyungbuk, province this plan presented 7 visions; such as foods-life, knowledge-brain, precisious environment, resouces-saving, export-market, traditional- specialization and development-participation agriculture and 7 basic strategies; such as environment-stabilization, speciality-discrimination, standard-modeliztion, demand-market, field-practicality, management-information, specialization-cooperation strategy. The major contents of this plan were presented to achieve strengthen -ment and advancement of competitive power on the agriculture of Kyongbuk; 21 superme technologies get to develop the highest technique, 21 major conventional projects will be mown continuously, 21 main clops snakes to intensify competitive power. Wheras, we will be propulsed 21 special projects for increasing a phase of Kyongbuk R D. A. and we inculuded 74 items of Si-Gym region for balanced development of area This plan consisted of 1,730 items in 84 fields and about 260 billion won will be invest every year. When it is finished successfully in 10 years, agricultural technical level of Kyungbuk will be not only promote to $80{\sim}90%$ level to advanced country, but also clanged to competitive industry, and farming villiages might be changed to a space of comfortable life.
