Plant, civil engineering and construction equipment data of overseas construction are obtained and then analyzed, classified and integrated by experts. With those refined data set, we built classification system and defined property information with reference to international standard (ISO 15926, IRDL). If class in ISO 15926 is predefined for equipment of interest, we used the class as is. If not, we created and defined new classes on the basis of ISO 15926 classes. If there is similar class for equipment of interest, extension or inheritance methods were used. As a result, classification system of five levels and 637 classes were built and construction equipment information were expressed in open structure of XML such as tree structure of classification system and detailed information with number equipments for each specific equipment. We also developed the electronic catalog system which is basically equipment information management system providing various product search functions.

First, the purpose of this research is to review the Online Dispute Resolution (ODR) regulations in Korea to resolve disputes which can arise in international e-commerce in the near future. Second, this research tries to look for alternative solutions to dispute resolutions according to these regulations. Third, this research pursues to enhance the effectiveness of business deals by providing efficient and satisfactory dispute resolution methods for e-commerce business. Furthermore, this study evaluates the definition of global e-commerce by comparing Online Dispute Resolution (ODR) with Alternative Dispute Resolution (ADR). Through analyzing the domestic ODR system and ADR system, this research could boost the employment of settlements in small-sized disputes through easy and convenient consumer access to both ODR and ADR procedures. The enhancement of the competitiveness of Korean companies in the global market is estimated to take place as a result. This research is estimated to provide benefits to our businesses both domestically and internationally by using ODR regulations and ADR methods. Moreover, this research is anticipated to verify usefulness in terms of consumer protection by advancing consumers' access to dispute solution authorities locally and abroad.

Poly(trimethylene terephthalate-co-trimethylene 2,6-naphthalate)s (P(TT-co-TN)s) with various copolymer composition were synthesized, and their chain structure, thermal property and crystalline structure were investigated by using $^1$H-NMR spectroscopy, differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD), respectively. It was found from sequence analysis that all the P(TT-co-TN) copolymers synthesized have a statistical random distribution of TT and TN units. It was also observed from DSC thermograms that the glass transition temperature increases linearly with increasing the TN comonomer content, whereas the melting temperature of copolymer decreases with increasing the corresponding comonomer content in respective PTT- and PTN-based copolymer, showing pseudo-eutectic melting behavior. All the samples melt-crystallized isothermally except for P(TT-co-66 mol % TN) exhibit multiple melting endotherms and clear X-ray diffraction patterns. The multiple melting behavior originates from the dual lamellar population and/or the melting-recrystallization-remelting. The X-ray diffraction patterns are largely divided into two classes depending on the copolymer composition, i.e., PTT and PTN $\beta$-form diffraction patterns, without exhibiting cocrystallization.

Membrane strip 면역 크로마토그래피 방법을 이용하여 정량분석을 수행하기 위해 스크린프린팅 기술에 의해 제작된 membrane 전극 상에 항체를 고정화하였고 신호발생물질로써 전도성고분자인 polyaniline이 결합된 colloidal gold를 사용하였다. 이때 사용이 적합한 전도성 고분자는 수용액에 대해 용해도가 높아야 하고 또한 면역반응 최적조건인 중성 pH에서 전기전도도를 유지할 수 있어야 한다. 이를 위해 기존의 polyaniline을 $LiPF_6$로 doping 하거나 새로운 수용성 고분자인 LEB-SPAN을 사용하여 전기전도도 측정용 면역 gold를 합성하였다.

최근 국내에서는 이상기온으로 인한 국지성 폭우와 여름철 태풍과 집중호우로 인한 다양한 재해 유형 중 산악지역을 중심으로 토사재해의 피해가 증가하는 추세이다. 국내 지형의 특성상 국토의 65% 이상이 산지로 형성되어 있어 개발이 필요하며 급격한 도시화로 인해 급경사지 및 산지가 도심지와 인접해 있다. 지속적인 도시화 산업화로 인하여 주거지 및 산업단지에 대한 피해가 지속적으로 증가하고 있으며, 도심지 인구밀도가 높은 우리나라는 토사재해 발생 시 그 피해 규모가 외국과 달리 크게 발생하고 있다. 최근 10년간(2001~2010년) 연평균 인명피해 68명, 재산피해 1조 7,044억원과 비교해 볼 때 인명피해는 20%, 재산피해는 25%, 수준으로 감소하는 것으로 보이지만, 도심지의 피해는 오히려 증가하고 있다. 이와 같은 도심지 토사재해를 예방하기 위해서는 도심지의 건물 등을 고려하여 시뮬레이션이 가능한 토사재해 3D 시뮬레이터 개발이 필요한 실정이다. 본 논문에서는 3D 시뮬레이터 개발을 위한 자료 수집 및 분석 및 현재까지 개발 된 시뮬레이터를 통해 실제 피해지역인 우면산의 피해상황을 가시화를 실시하여 시뮬레이터의 성능을 검증하였다.

Insulator is being used for material of railroad vehicles as a barrier of heat and noise. But it shows various fire properties in case of fire. In this study, we compared smoke density(Ds) values of rubber foams with the different thickness of glass fiber cross-Al foil according to the standard of ASTM E 662. The result showed that the insulator and barrier property played an important role in decreasing the value of smoke density

As an era of nano science approaches, the understanding on the shape and optical properties of various materials in a nanoscale range is getting important more seriously than ever. Accordingly the development of high spatial-temporal-spectral resolution measurement tools for characterization of nanomaterials/structures is highly required. Generally, the various properties of sample can be measured independently, e.g. to observe the structural property of sample, we use the scanning electron microscopy or atomic force microscopy, and to observe optical property, we have to use another independent measurement tool such as photoluminescence spectroscopy or Raman spectroscopy. In the case of nano-materials, however, it is very difficult to find out the same position of sample at every different measurement processes, and the condition of sample can be changed by the influence of first measurement. The tip enhanced Raman scattering(TERS), which can simultaneously measure the two or more information of sample with nanoscale spatial resolution, is one of solutions of this problem. In this talk, I will present our recent nano Raman scattering data of graphene that measured by TERS and optimized tip fabrication method for efficient experiment.

The $SnO_2$/(n)Si solar cell was fabricated by electron beam evaporation method, and their properties were investigated. In proportion to increase of substrate and annealing temperature, the conductivity of $SnO_2$ thin film was increased, but its optical transmission decreases because of increasing optical absorption of free electrons in the thin film. $SnO_2$/Si Solar cell characteristics were improved by annealing, but the solar cells was deteriorated by heat treatment above 500[.deg. C]. The optimal outputs of $SnO_2$/Si solar cell through above investigations were $V_{\var}$:350[mV], $J_{sc}$ ;16.53[mA/c $m^{2}$], FF;0.41, .eta.=4.74[%]

This study is aimed for investigating the rheology property and fluidity of superplasticizer which is necessary using for high flowing concrete fluidity establishment. Therefore, this study is analysis the rheology property and fluidity by different according temperature and elapsed time. From the results, the fluidity and rheology value were different according temperature. Over 2$0^{\circ}C$, the flow value of A, B, C, D, E type is increased, according as the increase of temperature, but the flow value of F type is decreased.
