Carbon fiber/epoxy composites using electrodeposited monomeric and polymeric coupling agents were compared with the dipping and the untreated cases. Treating conditions such as time, concentration and temperature were optimized. Four-fibers embedded micro-composites were prepared for fragmentation test. Interfacial properties of four-fiber composites with different surface treatments were investigated with simultaneous acoustic emission (AE) monitoring. The microfailure mechanisms occurring from fiber break, matrix and interlayer crackings were examined by AE parameters and an optical microscope. It was found that interfacial shear strength (IFSS) of electrodeposited carbon fibers was much higher than the other cases under dry and wet conditions. Well separated and different-shaped AE groups occurs for the untreated and ED treated case, respectively.

According to previous reports, antioxidant activities of Codonopsis lanceolata could be increased by a steaming process. This study was performed to improve its antioxidant activity and skin whitening activities of C. lanceolata by high pressure and stepwise steaming complex process. The complex processed C. lanceolata showed highest free radical scavenging acitivity as 45.21%, and for phenol and flavonoid contents, complex processed C. lanceolata contained higher than those from conventional extraction process or steaming process alone. The Cytotoxicity of all C. lanceolata extracts also showed low cytotoxicity against human fibroblast cell (CCD-986sk) as 4.49 ~ 10.40%. In whitening activity, high inhibition of tyrosinase activity was estimated as 25.08% by adding the extracts from complex process. We found that whitening and antioxidant activity of complex processed C. lancolata extract was higher than those obtained from conventional extraction and a steaming process because various kinds of antioxidant compounds could be easily released by combined process, compared to one of each process.

A study of pulmonary diseases in the slaughtered cattle (n = 125) of Mymensingh town was conducted to study pathological findings using the standard methods from September 2001 through April 2002. The pulmonary lesions observed in this study included congestion, emphysema, anthracosis, pleuritis abscess and hemorrhage. The histopathological findings of congestion were characterized by hemorrhage, a large number of leukocytes infiltration in the lumen of the alveoli, bronchitis, bronchiolitis, proliferation of fibrous connective tissue and hyperplasia of bronchiolar epithelia. Histopathologically, emphysema was identified by the distended alveoli with thin and atrophied alveolar walls. In anthracosis, carbon particles were found in stroma and alveolar lumen. In pleuritic lesions, there was a proliferation of fibrous connective tissue along with the infiltration of mononuclear reactive cells. Abscesses were characteristic of the accumulation of neutrophils surrounded by immature fibroblasts forming a capsule like structure.

With accommodation of a population of many young people and families due to Hangang River New Town Housing Project and development of railway station spheres, a need is increasing to improve the quality of public libraries service for Gimpo citizens and to establish more libraries. This study thus analyzed the book lending data of Gimpo City libraries, and the city's libraries-related social media big data in an effort to forecast the users, and thus to propose four library service improvement measures. First, in terms of book gathering and book development policy plans, a proposal was made to expand good books for children and youth, and to expand general original-language books related to learning of English, and English books for children. Second, in terms of the establishment of additional libraries or specialization strategy, a proposal was made to establish exclusive children's libraries or English libraries, and to establish library specialization strategy with a focus on children and English themes. Third, in terms of library culture programs, a proposal was made to provide library culture programs in relation to children education and to expand weekend library culture programs. Fourth, in terms of library facilities, considering the convenience of parking facilities, a proposal was made to establish libraries near apartment complexes.

We have fabricated high-$\textrm{T}_c$ superconducting $\textrm{YBa}_{2}\textrm{Cu}_{3}\textrm{O}_{7-x}$(YBCO) grain boundary junctions at a step-edge on (001) $\textrm{SrTiO}_3$(STO) substrates. A diamond-like carbon (DLC) film grown by plasma enhanced chemical vapor deposition were used as an ion milling mask to make steps on the STO (100) single crystal and was removed by an oxygen reactive ion etch process. The c-axis oriented YBCO and TO thin films were deposited epitaxially on the STO substrate with a step-edge by pulsed laser deposition. The grain boundary junctions were formed at the top and the bottom of the step. The junctions worked at temperatures above 77 K, and had I\ulcornerR\ulcorner products of 7.5mV at 16K and 0.3 mV at 77K, respectively. The I-V characteristics of these junctions showed the shape of the two noisy resistively shunted junction model.

Administrative procedures are the heart of the activity in each Town Council. Citizens do transactions every day and, sometimes, they do not understand what they must do or the steps to follow. We are developing a Web-based system to help citizens with this task in an easy way. The application is integrated a four year project called Albacete[Digital] that began in 2002 with the purpose of building an e-government system in Albacete, a city with over 150.000 citizens. This Administrative Information Centre is the result of the Administration study in the first year of the project and it will continue with the on-line transaction in the following years.

The landscape structure of the both pre-industrial and industrial cities should be influenced to the topographical feature , religious thoughts, political ruling system and history. In the major socio-cultural factors in the pre-industrial townscapes in korea, the Feng - Shui(poongsu) which is an acient human settlement organization system based on the “Yin - Yang” principle and “Five Elements” and “Chryaegogong”system were the most important factors to the formation of traditional town scape in Korea. The landscape during the Japanese colonial periods were basically reorganized through change of “Boundary”, “Center” “Direction(path)” and “Domain” which were expressed by distinct traditional townscape in Yi dynasty. The physical shapes, meanings and behaviors of townscape were expressed properly of the intention of the colonization. As changes to the mordern industrial cities, the townscape had been amended landscape elements of the Japanese imperialism to an ideology of rebirth nation. Also as changes to the modern industrial cities, “Boundary”, “Center”, and “Domain” spreaded into the suburbs by funtionalsm and these were expressed an incoherent value system which were the advancement of growth, pursuit policies as well as an advancement of science techniques.

When constructing buildings, planning, design, construction, using & maintenance as building life cycle. Due to industrialization in 1960s and development of new town from the late 1980s to the early 1990s, Korean housing supply rate reaches almost 100%. After construction companies confronted limit of new building construction, they recognized remodeling as a part of construction, and organized remodeling team or FM team to improve sustainable industrial area. However, since companies in Korea are lack of experience and research activities for remodeling, it makes obstacle to improvement of remodeling business. So the objective of this study is to help carry out remodeling business by suggesting the counterplan through investigation of a risk of apartment remodeling business.

Tracer experiments were performed 4 times in December 1992 on the relatively flat terrain and nearby building area adjacent to the Taedok Science Town in Korea. Each experiment was continued for relatively short period of 1 or 2 hours with intermittent release of SF6 up to 2.07g/s at 10m height. Movement of tracer plume was tracked by a continuous tracer analyzer installed on an air monitoring van. Simulation with INPUFF was carried out to analyze and predict experiments. Measured profiles of tracer plume were narrow and sharp while predicted profiles by INPUFF were broad and slowly varied. Tracer plumes were detected at a short distance of 0.5 to 2.2 km mainly due to intermittent release and high value of lower detectable limit. Various experimental conditions were tested by INPUFF simulation in order to find desirable conditions. Higher wind speed and less variable wind direction could yield longer distance of plume tracking only when the lower detectable limit was sufficiently low. Distance of plume tracking was long and did not much depend on the lower detectable limit in stable atmospheric conditions.
