Intelligent Manufacturing Systems (IMS) Program is an industry-driven and government-endorsed initiative which assists and encourages the formation of international research consortia to address technical and other emerging manufacturing challenges in the 21$^{st}$ century$^{[1]}$ . The IMS initiative places special emphasis on the establishment of R＆D projects which demonstrate equitable cooperation, including the protection of intellectual property. In this explanatory paper, a brief overview of the IMS Program is described, together with abstracts of some selected projects and a research result of Globeman21 project. The IMS prospective is also given.n.

Recently, robot research and development was interesting the inside and outside of the country. Medical robot surgery showed diverse advantages according to advanced technical robot research. Also the academic society, research institute and industry showed concerning to the medical robot system. There is a growing need to introduce medical research for aging society. The surgical landscape is quickly changing because of the major driving force of robotics. Robot system and biomedical engineering research as defined a new engine of development show present ways of future revitalization of medical robot system. Medical robot system will be even more utilized when we keeps trying to combine high biomedical technique, IT research, and robot technique. In this review article, we begin with a short historical review of medical robotics, followed by an overview of clinical applications where robots have been applied.

The European Standards Organisation (CEN) has planned to develop a complete set of harmonized European building standards. The Eurocodes, being the design standards, form part of this total system of European standards, together with standards for fabrication and erection and product standards. After a period of experimental use of the ENV(European Pre Standard)-versions of the Eurocodes, these are now converted into official EN's (European Standards). Design of composite steel and concrete buildings and bridges is covered by Eurocode 4. An overview will be given of the historic development of Eurocode 4, the structure and contents of the EN version and the present status and planning for completion. The Eurocode treatment of some selected technical items will be presented in more detail.

MPEG audio uses the masking effect, high frequency component synthesis based on spectral band replication, and channel expansion based on parametric stereo for efficient compression of audio signals. In this paper, we present an overview of the state-of-the-art channel expansion technology in MPEG audio. We also present technical overviews and application examples to broadcasting services for HE-AAC v.2, MPEG Surround, spatial audio object coding (SAOC), and unified speech and audio coding (USAC) which are MPEG audio codecs based on the channel expansion technology.

This technical paper contains the information of the Dye-Sensitized Solar Cells (DSSC) working principal where diffusion mechanism acts as electron transport to absorb the sunlight energy to generate the electrical energy. DSSC is photo electrochemical cell that implements the application of photosynthesis process. The performance of electron transport in DSSC has been reviewed in order to enhance the performance and efficiency of electron transport. The improvement of the electron transport also discussed in this paper.

The purpose of this paper is to review recent developments in lower limb exoskeletons. The exoskeleton system is a human-robot cooperation system that enhances the performance of the wearer in various environments while the human operator is in charge of the position control, contextual perception, and motion signal generation through the robot's artificial intelligence. This system is in the form of a mechanical structure that is combined to the exterior of a human body to improve the muscular power of the wearer. This paper is followed by an overview of the development history of exoskeleton systems and their three main applications in military/industrial field, medical/rehabilitation field and social welfare field. Besides the key technologies in exoskeleton systems, the research is presented from several viewpoints of the exoskeleton mechanism, human-robot interface and human-robot cooperation control.

The global demand for underground facilities has increased substantially in the past decades, and a substantial number of underground projects have had to deal with challenging ground conditions in urban environments. Particularly challenging are weak and unstable water bearing soils. Advancements in shielded TBM tech-nology have led to significant improvements regarding the ability to control ground deformations in soft ground. Nonetheless, ground collapse may occur even when the most advanced TBM designs are employed if unexpected adverse ground conditions are encountered or if insufficient stabilizing pressure is transferred to the tunnel face. This paper reviews common approaches for face stability and face pressure transmission calculations, and provides an overview of some of the latest technological developments and considerations for soft ground TBM applica-tions.

The purpose of this study was to review the current status and problems of the national qualification system in the Environmental field focusing on deficiencies of the regulatory system and qualities of environmental professional including the Environmental control Professional Engineer, Environmental Engineer, Environmental Industrial Engineer and Environmental field. An overview of the environmental field, its current status, domestic qualification items and training conditions in environment-related areas, laws of environmental field, and data of the job analysis were reviewed. The concrete and extensive development plans for the qualification system of the Environmental field are as follows: First of all, a job analysis should be made of on the introduction of new systems or policy modification to reflect technical changes and national policies about the environmental field in the qualification exam. Second, it is essential to prepare policies that are suitable for the qualification system in the Environmental field and that improve its effectiveness. Third, the appropriate policy measures should be taken in order to elevate the social standing of Environmental field qualification holders.

과학기술의 발전으로 세계 각국의 경쟁은 지상을 넘어 우주로 나아가고 있다. 현재 미국을 비롯한 세계 우주기술 선진국들은 달 및 행성탐사 우주선 개발과 같은 유인 우주기술 개발에 박차를 가하고 있다. 따라서 미국, 러시아, 유럽연합(독일, 프랑스 등 11개국), 캐나다, 일본을 중심으로 운영되고 있는 우주정거장은 유인 우주행성탐사 시 생명체 유지에 필요한 시스템 개발과 검증을 위한 기초/응용과학 실험실로 활용되고 있다. 특히 우주환경에서 화재의 발생과 감지/소화의 메카니즘을 이해하고자 다양한 연소실험이 이루어지고 있다. 본 논문에서는 가장 기본적인 우주환경인 미세중력환경에서의 화염의 점화 및 형상특성을 고찰해보고 우주환경 화재안전에 관한 일반적인 내용을 기술하였다.
