North Korea has stressed Information Technology in policy fostering science as Kim Jong-il has been interested in IT industry. In view of development of e-business in Northeast Asia, South Korea is to cooperate with North Korea. It is the time to look into the current situation, strategy and issues of IT in North Korea. Although North Korea is forced to select the development of IT Industry as growth engine, the problems in the IT Infrastructure are as follows:lack in communication infrastructure, lack in diversity of software, low level of hardware, limited use of internet. This paper deals with the IT Infrastructure of North Korea and IT and e-Commerce Cooperation, introduction of e-Trade between South and North Korea.

Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

택지개발사업비에서 간선시설 설치 비용이 차지하는 비중은 상당히 높으나, 부과의 행정적 편의상 일정규모 이상의 사업시행자가 부담하는 경향이 크다. 이로 인해 주변 기성시가지 및 소규모 택지개발사업지구에서 설치된 간선시설에 무임승차하게 되는 경우가 빈번하여 분담의 형평성 및 개발이익의 사유화 문제를 노정하고 있다. 이 연구는 대규모 택지개발사업에서 설치되는 도로시설의 무임승차를 파악하기 위한 방법론을 정립하고 실증분석하여, 합리적인 간선시설 비용분담을 위한 합리적 근거를 제시한다. 실증분석을 위한 사례지구로 부천상동택지지구를 선정하였다. 부천상동지구에 의한 교통유발을 도출하기 위해 개발시나리오를 설정하였으며, 교통네트워크 분석을 사용하여 간선시설을 이용하는 교통량, 통행시간, 통행비용을 시나리오별로 산출하였다. 그 결과, 부천상동택지지구 주요 간선시설 중 당해 지구가 부담해야 할 비율은 전체의 83% 정도로 분석되었다. 이 연구의 방법론과 결과는 향후 개발사업에서 간선시설 설치를 위한 비용의 부담주체와 부담정도를 설정하는데 기여할 수 있을 것이다.

최근 자율주행에 관한 관심은 자율주행차량의 주행기술 개발과 함께 주행환경을 이루는 인프라 개발을 함께 고려하는 자율협력 주행이 주목을 받고 있다. 자율협력 주행의 개념에 따라 본 연구에서는 기존 정밀도로지도의 정보를 보완할 수 있는 자율주행을 위한 신규 인프라를 분석하고 해당 인프라를 정밀도로지도에 추가하는 방안을 연구하였다. 자율주행을 위한 신규 인프라는 개선 물리 시설물 2종과 센서 전용 물리 시설물 1종을 제시하였다. 정밀도로지도 분석 결과 분기점과 같은 정보는 거의 변화하지 않는 정보이지만 분기점에서 발생할 수 있는 장애물에 주의하라는 의미 전달을 위해 자율주행을 위한 인프라를 추가할 수 있을 것으로 예상된다. 이와 같이 자율주행을 위한 신규 인프라는 기존 도로 시설물이 수행하는 안내, 지시, 주의 환기 등의 역할을 지원해야 할 필요가 있다.

Global Flood Alert System (GFAS) is an attempt to make the best use of satellite rainfall data in flood forecasting. The project of GFAS is promoted both by Ministry of Land, Infrastructure and Transport-Japan (MLIT) and Japan Aerospace Exploration Agency (JAXA), under which Infrastructure Development Institute-Japan (IDI) has been working on the development of Internet-based information system and just launched trial run of GFAS in April 2006 on International Flood Network (IFNet) website. The function of GFAS is to connect space agencies and hydrological services/river authorities in charge of flood forecasting and warning by providing global rainfall information in maps, text data e-mails and so on which is produced from binary global rainfall data downloaded from National Aeronautics and Space Administration (NASA) website. Although the effectiveness of satellite rainfall data in flood forecasting and warning has yet to be verified, satellite rainfall is expected to play an important role to strengthen existing flood forecasting systems by diversifying hydrological data source.

Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

In this work, a comparative study of multi-objective meta-heuristics (MOMHs) for optimum design of a walking tractor handlebar is conducted in order to reduce the structural mass and increase structural static and dynamic stiffness. The design problem has objective functions as maximising structural natural frequencies, minimising structural mass, bending deflection and torsional deflection with stress constraints. The problem is classified as a many-objective optimisation since there are more than three objectives. Design variables are structural shape and size. Several well established multi-objective optimisers are employed to solve the proposed many-objective optimisation problems of the walking tractor handlebar. The results are compared whereas optimum design solutions of the walking tractor handlebar are illustrated.

In this study, the Discrete Element Code was applied to the analysis of falling rock blocks. The simulation was performed using the PFC2D computer code. Falling rock blocks should be applied as additional force to each others. The force affect the motion of falling rock blocks. This was used to find out the behavior of each blocks. This study revealed that the DEM can successfully capture the behavior of falling rock blocks.
