Nowadays, the demand of civil application of an UAV has been being increased all over the world. And many projects are going on to develop a new regulatory system for an UAV to access a national airspace. Especially, to fly UAV over the non-restricted airspace as a standard airworthiness standard, many authority funded research institutes and associations are studying regulatory environment. For the UAV to access civil airspace, the certification system of the aviation regulation have to allow this. FAA of US, CASA of Australia and European authorities are now issuing an experimental airworthiness certificate to a civil UAV. This is the first step of issuing a standard airworthiness certificate. And many people believe that civil UAV can fly over a NAS if some technical issues are resolved. In this study, I would like to present an international trends of a civil UAV regulation system, reliability trend of unmanned aerial system and would like to bring up a our regulatory environment and suggest an UAV regulatory policy.

The enforcement of the Kyoto Protocol to reduce greenhouse gas is definitely a challenge we cannot avoid. Korea ranks 10th in the world and 1st among OECD countries in terms of the volume of greenhouse gas emission and is expected to join Annex I countries which have to reduce emission after 2012. For the sustainable development, we shouldn't depend upon fossil fuel energy longer. This study will provide preliminary data to developing renewable energy systems for urban generation. There are investigated a recent case study of CONCERTO projects co-funded by the European Commission and analyzed application of renewable energy systems as a urban energy source.

$Epichlo\ddot{e}$ endophytes, including Neotyphodium spp. and $Epichlo\ddot{e}$ spp., enhance plant growth, mediate more plant tolerance or resistance to biotic and abiotic stresses, and also synthesis various biologically active compounds in their host plants, and important in many areas. In early stages, most of $epichlo\ddot{e}$ endophytes were described during surveys practiced by American, European and Oceania scientists, while fungal endophytes within native Asian plants were poorly investigated. In recent years, an $Epichlo\ddot{e}$ sp. and 4 Neotyphodium spp. were described in cool season Chinese native gramineous plants. Most of Chinese native Neotyphodium spp. were presumed as hybrids originated from members of ETC and EBY. Investigation on NRPS genes shows lack of toxic ergopeptines and potential production of peramine. Biological and ecological roles of Chinese native $epichlo\ddot{e}$ endophytes should be investigated in future, and it will be very valuable if we can have some joint projects with Korean scientists for Asian native $epichlo\ddot{e}$ endophytes.

Currently, advanced countries such as European countries and Japan invest lots of efforts to develop improvement of electric power production and supply, environmental countermeasure, and renewable energy development. Accordingly, Korea has been putting efforts to all kinds of electric related technical development based on the mid-long term plan. Further, it is necessary to increase effectiveness of R&D investment by propelling joint research activities with advanced countries for development of important technologies. Based on this background, this study tries to find thought-provoking suggestions of energy projects, programs and policies. For a comparative analysis, Japan which is similar to Korea in terms of market size and policies, and EU where joint research has been actively carried out among nations are analyzed and compared to policies and joint R&D activities of Korea.

National projects on renewable energy and new energy are driven more actively than ever in many countries for the exhaustion of fossil fuel energy from the turn of the century. Such activities began to spread out in railway industry with centering around west European countries. Electric energy is generated on the hybrid vehicle itself, which contributes to reduction of the cost for construction of the infrastructure required for the supply of electric power. Hybrid tram is mainly composed of propulsion system to control electric energy, automatic guidance system to control steering and operation, and central vehicle unit to control and monitor major electronic devices. Generation and supply of electric power are made by the combination of engine generator and battery, or fuel cell and super capacitor.

As cognizance of necessity of environmentally friendly building is growing, techniques to construct environmentally friendly envelope of contemporary architecture is being changed and developed. Though the stream of times likes this, applications of those are focused on office buildings but rarely on residential projects. A begin of this study is to address analysis of environmentally friendly envelope techniques in urban housing in Europe constructed after 1995 which is the very time that the notion of ecological architecture. The result of this analysis should be a suggestion of radical data to make buildings be more buildings be more environmentally friendly and having amenities.

Sustainability assessments tend to integrate ecological, social, and economic concerns. Sustainability assessment could be considered the highest rung in the assessment ladder. Broad strategies that seek to integrate individual SEA(Strategic Environmental Assessment) could be subjected to a sustainability assessment. Sustainability assessment could incorporate global and transboundary effects and priorities into SEA and project-level EIA(Environmental Impact Assessment). SEA could provide an environmental context and direction for project-level EIA. Procedural and substantive EIA requirements can be addressed through tiering such as sustainability assessment, SEA, project-level EIA. In Korea, PERS(Prior Environmental Review System) that has been utilized to evaluate administrative plans related with various kinds of development projects should be evolved not only to incorporate environmental impacts into early stage decision-making, but also to implicate sustainability assessments that include social equity and economic efficiency. Integration of SEA and sustainability assessment can be initiated through the application of DPSIR (Driving Force - Pressure - State - Impact - Response ) framework that was developed by European Environmental Agency.

The purpose of this study is to analyze the concept of 'individual' found in architecture of British Archigram Group. Although many critics and historians have judged Archigram as a simple technocrat, the concept of individual employed by Archigram since their Living City Exhibition undermine their representational works. Archigram's concept of individual was basically influenced by the European historical context since the Renaissance and at the same time by the philosophy of existentialism. Since Archigram proposed their individualistic trend In the Living City Exhibition, they have created many individualistic architecture such as Living Pod, Cushicle, Suitaloon, etc. Through these experimental projects, Archlgram's concept of individual did not intend to get rid of the society itself, but to form a society based on the individual autonomy and on the interaction between individuals. In the city of Archigram, there was ultimately the new symbiosis between individual units and this symbiosis completed new world.

The purpose of establishing GPS networks of continuously operating reference stations (CORS) is aimed to assist land surveying or crustal deformation in the early stage. However, with a fast evolving and improving path the GPS technique has been extended to accurately measure atmospheric precip itable water vapor as a core objective of many projects developed in many countries and regions such as the SuomiNet (U.S., UNAVCO), COST716 (European, COST), GEONET (Japan, GSI), ...etc. In this paper, we present the current progress of the being-set-up GPS network in Taiwan whose atmospheric profile observations mainly count on the traditional radiosonde soundings as typically seen in any other part of the world. The GPS data collected from the Taiwan dense GPS network primarily supported by Central Weather Bureau are processed using the Bernese software version 4.2. Precipitable water vapor is then derived with the auxiliary surface meteorological measurements. Time series of precipitable water are examined and analyzed. A focus on the extreme weather cases is shown as an example.
