안종득(Jong-Deuk Ahn) 한국정보기술학회 2014 한국정보기술학회논문지 Vol.12 No.6
This paper presents a new method for classifying inferiority of vehicle engine harness based on visual inspection system. Visual inspection system are composed not only S/W algorithm which consist of color information, line tracking and color matching but also H/W module for object recognition and statistical processing as well. The proposed algorithm performed a series of tasks for acquiring engine image from CCTV camera, recognizing color, order, gap and length of cable, and automatic classifying the inferiority of vehicle engine harness. To testify the performance of implemented system, 1000 times of experiments are executed with respect to the ratio of recognition and false acceptance rate(FAR). Experimental results shows that recognition rate of 99.7% is evaluated regardless of wire direction and position, and under the same condition FAR is 0% respectively. In case of processing time, it results in average 200ms under, finally demonstrate the effectiveness of real-time processing.

Considering the recent substantial increase in national research and development (R&D) budgets in the energy sector there has been increased Interest in the effectiveness of government R&D investments. We conducted a case study to calculate the allowable scale and effectiveness of R&D investment by calculating the direct performance improvement effect resulting from R&D investment as an economic value. Using conditions that existed prior to R&D investments as a reference, five cases in which performance improved due to R&D investments were compared and analyzed. The government’s financial investment is increasing rapidly in line with the establishment of the national hydrogen roadmap. R&D is needed to enhance the current low technology readiness level of hydrogen fuel cells compared to solar and wind energy fields. Therefore, an R&D project to improve the performance of the fuel cell system was selected as this case study’s subject. Using the results in this study, the allowable level of investment in the task unit of national R&D projects could be calculated. Moreover, it is advisable to provide a standard for rational decision making for new R&D investments since it is possible to determine investment priorities among a large number of candidates.

최근 전세계적으로 신재생에너지에 대한 관심과 투자가 증폭되고 있으며, 우리나라에서도 그 간의 지속적인 연구개발 지원에 힘입어 국산기술 확보 및 산업화가 점차적으로 이루어지고 있는 것으로 분석되고 있다. 더욱이 신정부에서는 국정지표인 녹생성장의 실현방안으로 신재생에너지에 대한 지원을 대폭 확대하고 있어 관련 기술개발 투자도 지속적으로 확대될 것으로 보인다. 본 고에서는 이러한 국내 신재생에너지 기술개발 관련 정책 및 기술개발 동향에 대하여 알아보고, 특히 급속한 성장세 속에 2008년 전세계 태양전지생산량이 7.9GW1) 에 달한 태양광 분야는 우리나라가 강점을 갖고 있는 반도체, LCD 기술과 유사하여 국내의 축적된 기술과 인프라를 활용할 경우 조기에 세계수준의 기술력을 확보할 것으로 기대되고 있으며, 정부에서는 태양광 분야를 수출전략산업화 하기위해 집중적인 투자에 나서고 있다. 이러한 상황에서 그간의 기술개발 현황, 실적 및 향후 전망 등에 대하여 살펴보고자 한다.
구축사례를 통한 효율적 공공기관 EA 구축 방법론 제안

The Law of effective building and operation for the information systems took effect at Dec. 2005. Every government and public agency have to build own enterprise architecture(EA), sometimes it"s called the Information Technology Architecture(ITA), by this law. The Ministry of National Defense(MND) built the enterprise architecture(EA) during 2006. 12~2007. 11 by this law too. We knew the specific characters of the public sector thru the EA project. The public sector is less active than commercial sector and most members of the public sector are just looking on the project as a spectator. So the most of key for the success of EA is how to catch the Sponsorship and Participation of members. In this paper we propose the effective building methodology for the Enterprise Architecture of public agency applying the MND-EA. The other governments and public agencies can build own the EA easily by the proposed methodology.

The photovoltaic (PV) industry, which occupies about 80% share of domestic new and renewable energy (NRE) sales, has played an important role in the development of the Korean NRE industry. This was made possible by the government"s implementation of the 3rd Basic New and Renewable Energy Plan, which promoted strategic PV R&D, infrastructure building, and a variety of PV deployment programs. For instance, ‘One Million Green Homes’, ‘Feed in Tariff ’, and ‘Renewable Portfolio Standards’ programs contributed greatly to the dissemination of PV systems in the country. Furthermore, these programs were supported with more than 380 billion Won over 6 year period (2007~2012). The strategic PV R&D contributed to the fast follow-up in commercial technologies. Because of the recent, sharp decline in PV prices caused by oversupply and economic crisis in European countries, both foreign and domestic PV companies are going through painful restructuring. Under these circumstances, the Korean PV industry needs to find a new strategy for making a breakthrough, and in this sense a proactive role of the Korean government is desperately needed.

본 논문에서는 관리자가시스템 운영과 감사 측면에서 침해사고에 대응하고 사고 발생 즉시 포렌식 데이터를 수집 분석 및 복구할 수 있는 포렌식 데이터의 실시간 수집 절차 모델을 제안한다. 제안한 모델은 기능 요소별로 구별된 7단계 절차를 가지며 추상적이고 관리적인 기존의 포렌식 절차와는 달리, 관리자가 시스템 운영과 감사 측면에서 침해사고에 대응하고, 사고 발생시 포렌식 데이터를 수집 분석 및 복구할수 있는 절차들이 포함되어 있다. 또한 즉각적인 대응이 어려운 경우 기존의 절차와 마찬가지로 종합적이고 조직적인 대응이 가능하도록 대응 전략 체계화 단계를 통한 포렌식 데이터 수집 단계로의 피드백 절차를 둔다. This study proposes a model of collection process for real-time forensic data, in which the manager was to respond to infringement incidents in terms of system operation and inspection and to collect, analyze and restore forensic data immediately after an incident took place. The suggested model was modeled in seven processes according to functional elements. Unlike the old and managerial forensic processes, the model allowed the manager to react to infringement incidents in the aspects of system operation and inspection and to follow the processes of collecting, analyzing, and restoring forensic data in case of an incident. There also was a feedback process designed towards the step of gathering forensic data through the stages of systematizing reaction strategies in order that he or she be able to bring about comprehensive and structural responses to an incident like the former processes in which it is difficult to bring about instant responses.
