Hydro-environmental impact assessments (HEIA) in tunnel constructions have been performed through various methods including preliminary investigations, field tests, numerical simulations, and monitoring. Specially, it is very important to evaluate quantitatively groundwater inflows into tunnels as well as drawdowns caused by tunnelling. Obvious definitions between porous and fractured rock media in hvdrogeologic properties of study regions must be needed to execute HEIA for rational tunnel construction in fractured bedrocks. In this paper, we propose a HEIA on tunnel constructions in fractured rocks media resulted from various hydrogeologic field tests and numerical models on given regions and determination of systematic order, i.e. the technical road map (TRM) of HEIA. These systematic HEIAs are expected to be usefully applied to base data in tunnel construction in fractured rock media.

The current society, namely information society is now moving to a specific topic which is SMART. In this sense, recently a variety of social areas including communications and SOC domains are moving fast to this topic. In Korea, The electric power area has been doing a pioneering job relatively successfully and the water supply area is just now taking the first step. The purpose of this research is to develop a technical Framework for Smart Water Grid Service. Related researches has been studied and the 4 constituting technical element areas were defined first. For each of the four areas, a framework modeling was fulfilled and as a result, a TRM(Technical Road Map) was suggested for each of the area. Finally, an Enterprise TRM covering all of the 4 areas was described. Furthermore, the currently suggested Framework model was compared to a related model and it was found that the integration of the models is desirable to wholly cover from Macro to Micro level applications and services. It is expected that the current approach contribute, more or less, to the smart implementation in the areas of water management.

In this paper, we offer a new strategic portfolio model for national IT R&D project selection in Korea. A risk and return (R-R) portfolio model was developed using an objectively quantified index on the two axes of risk and return, in order to select a strategic project and allocate resources in compliance with a national IT R&D strategy. We strategize using the R-R portfolio model to solve the non-strategy and subjectivity problems of the existing national R&D project selection model. We also use the quantified evaluation index of the IT technology road map (TRM) and the technical level reports (TLR) for the subjectivity of project selection, and try to discover the weights using the analytic hierarchy process (AHP). In addition, we intend to maximize the chance for a successful national IT R&D project, by selecting a strategic portfolio project and balancing the allocation of resources effectively and objectively.

지난 10여년간 한국 사회는 기술적, 경제적, 정치적으로 많은 성장과 변화, 그리고 발전을 거듭하여 세계 13의 경쟁력을 자랑하고 있다. 하지만, 우리나라의 사회적 성장 수준은 세계 30위에 그치고 있어 노령화 정책, 환경 문제, 양극화문제, 균형 발전 등의 사회적 성장과 삶의 질 향상을 위한 노력이 필요한 상황이다. 지속가능한 안전한 삶에 대한 국민적 관심과 요구가 높아지고 있음에도 불구하고 우리 사회는 일상생활과 밀접한 전기 화재 및 가스 사고에서부터 국가 산업 경쟁력 및 심각한 환경문제까지 야기할 수 있는 발전소 혹은 대형 플랜트 사고에 이르기까지 위험 요소를 안고 있다. 이에 본 연구는 이러한 에너지 관련 시설 및 활동으로부터 발생할 수 있는 사고를 예방하고 조치할 수 있는 안전 기술 개발 현황에 대하여 조사하고 이를 바탕으로 향후 국내 에너지 안전 기술의 개발 방향에 대한 의견을 제안하였다. 또한, 국내 가스 및 설비 안전 기술의 현황을 파악하고 이를 토대로 안전 기술의 유형을 분류하여 향후 관련 기술의 방향성 제시를 위해 중장기 TRM(technical road map)을 제시하여 에너지 안전 기술의 경쟁력 확보를 위한 토대를 마련하였다.
