다가올 유비쿼터스 시대를 선도할 기술 중 하나인 USN(Ubiquitous Sensor Network)은 산업 전반에 커다란 변화를 가져올 것으로 기대된다. USN은 각종 센서 노드로부터 사물 및 환경 정보를 감지, 저장, 가공, 통합하고 상황인식 정보 및 지식 콘텐츠 생성을 통하여 언제, 어디서. 누구나 원하는 맞춤형 서비스를 자유로이 이용할 수 있는 첨단 지능형사회의 기반 인프라이다. USN과 더불어 이를 활용하기 위한 USN 어플리케이션의 개발들이 늘고 었으며 이에 USN 미들웨어의 필요성 또한 증가하고 있다. USN 디렉토리 서비스는 USN 미들웨어를 구성하는 핵심 서비스 중 하나이며, 지역적으로 분산된 USN 자원에 대한 정보를 관리하고 USN 자원에 대한 검색을 실시간으로 제공하는 서비스이다. USN 자원은 고정된 자원과 이동성을 지닌 자원으로 나눌 수 있다. 하지만 현재 이동성을 지닌 센서 노드(Mobile Sensor Node)를 지원할 수 있는 USN 디렉토리 서비스는 보이지 않고 있다. 본 논문은 이러한 Mobile Sensor Node의 특성을 지원하는 USN 디렉토리 서비스의 모델들을 제시하고 그에 대한 설계 및 구현을 논한다.

This study was to reveal consumer attitudes about open shelf-life dating method of the packaged foods. Consumers consider that open shelf-life dating to the packaged foods gives good information to choose the products to buy, but also confusion with unclear open shelf-life dating marked on the package. For the perishable foods, consumers tended to get more attention to the open shelf-life dates. Consumers prefer the dating method of edible periods better than sellable periods to the packaged foods. The female consumers consider that open shelf-life dating is more important to buy the packaged foods than male consumers do.

USA and Europe are leading a transport airplane industry. In Asia-Pacific region, air transportation and MRO industries are forecasted to be grown up rapidly. Furthermore, Japan and China entered into design and manufacture state of regional airplane, and developing countries entered into severe struggle competition for MRO industry. Global aircraft MRO and engine MRO industries are forecasted 3.4% and 7% growth respectively in next decade. In this paper, authors propose promotion strategy for technology intensive MRO of aircraft engine to create a higher value-added business.

A ground penetrating radar survey with a 500 MHz radar antenna was applied to make archaeological investigation in Nakajima of Ishikawa Prefecture, Japan. The ability of the radar system to aid in the archaeological preservation of burial ground was the primary concern of the experiments. The average variance of the radar wave returned from progressively deeper reflectors in a tomb were contoured at 2.4 nanoseconds intervals. The results of analysis indicates the location of trenches and the coffin area at the tomb site. The orientation of the coffin is dearly defined on contour maps made below 9.6 nanoseconds horizon. The general features detected by the GPR were also reconfirmed by electric resistivity survey made at the site. The radar was accurate in ascertaining the location, orientation, and the general construction style of the coffin.

Furthermore, Japan and China entered into design and manufacture state of regional airplane, while developing countries entered into severe struggle competition for MRO industry. Global aircraft MRO and engine MRO industries are forecasted 3.4% and 7% annual growth respectively in the next decade. In this paper, authors propose promotion strategy for technology intensive MRO of aircraft engine to create a higher value-added business.

In the process of site selection for a radioactive waste disposal, site characterization must be carried out to obtain input parameters to assess the safety and feasibility of deep geological repository. In this paper, methodologies of site characterization for radioactive waste disposal in Korea were suggested based on foreign cases of site characterization. The IAEA recommends that site characterization for radioactive waste disposal should be performed through stepwise processes, in which the site characterization period is divided into preliminary and detailed stages, in sequence. This methodology was followed by several foreign countries for their geological disposal programs. General properties related to geological environments were obtained at the preliminary site characterization stage; more detailed site characteristics were investigated during the detailed site characterization stage. The results of investigation of geology, hydro-geology, geochemistry, rock mechanics, solute transport and thermal properties at a site have to be combined and constructed in the form of a site descriptive model. Based on this site descriptive model, the site characteristics can be evaluated to assess suitability of site for radioactive waste disposal. According to foreign site characterization cases, 7 or 8 years are expected to be needed for site characterization; however, the time required may increase if the no proper national strategy is provided.

Consolidation properties of Shihwa deposits were analysed by means of depositional environments. Depositional environments including particle size distributions, sediment structures, geochemical properties, porewater chemistries and carbon age dating were analysed using undisturbed samples retrieved successively from a boring hole in the study area. Laboratory oedometer tests and anisotropic consolidated triaxial tests (CKoUC) for undisturbed samples were performed to examine the overconsolidation phenomena. Based on the results of analysis of depositional environments, it was found that the upper silt/clay mixed layer was deposited under marine condition while underlying sand and clay layers were deposited under fluvial condition. Planar laminated structures of silts and clays were dominant in marine deposits. Although there was no clear evidences that geological erosion had occurred in marine deposits, overconsolidation ratios of the upper marine samples were greater than unity Stress Paths of the upper marine samples behaved similarly to those of normally consolidated clays. Data plotted in stress state charts showed that the marine deposits were normally consolidated in geological meaning. These apparent overconsolidation of the marine deposits can be explained by the structures i.e. chemical bonding due to the difference of the rate of deposition, not by geological erosions and ground water fluctuations.

The government real estate policy has repeatedly relaxed and reinforced controls under the mutually contradictory targets. Switching over the supporting policy after the IMF crisis to the regulating policy from 2003, the government housing policy began to generate ill effects due to various regulations. This stud carefully investigates and statistically tests the transmissions of variations in the housing prices between the metropolitan areas in the early stage of the preceding administration, under the effect of the supporting scheme, and those in the late stage, under the effect of the restricting scheme. The distinctive feature between the two periods is found to be much simplified interrelationships of the price variations in the latter period. Consolidated leading role of capital sphere, by concentrated economic strength, suggest the obvious imbalance between variations in the metropolis housing prices.
