  • Pantograph, which collects current from cartenary system, is one of important parts of high-speed train. Kinematic analysis is basic component of pantograph design. But kinematic analysis is very complex and time-consuming. Therefore numerical calculation of pantograph kinematics is necessary. In this study, pantograph kinematic analysis software was developed and relationship between kinematic parameters and pantograph performance was investigated. The software and relationship between kinematic parameters and pantograph performance are helpful to pantograph designers

  • beta-Amyloid (A$\beta$) peptide is the major component of senile plaques and considered to have a causal role in the development and progression of Alzheimer's disease. There has been compelling evidence supporting that $A\beta$-induced cytotoxicity is mediated through oxidative and/or nitrosative stress. Recently, considerable attention has been focused on dietary manipulation of oxidative and/or nitrosative damage. L-Egrothioneine (EGT) is a low-molecular weight naturally occurring thiol compound of dietary origin which exists in milimolar concentrations in the brain, liver, kindney, erythrocytes, ocular tissues and in seminal fluids of mammals.

  • In this study, the product design technology to facilitate the assembly automation is developed. First, checkistis are developed to analyse weakpoints which make assembly automation difficult. The weakpoints of assembly automation can be redesigned by using design rules for assemblability which are systematized in this research. In addition, the assemblability of product can be evaluated qualitatively with the new developed assembly evaluation method. This evaluation method is performed in the respect of the component parts, the assembly method and the assembly motion.

  • Service-oriented computing systems have been issued by their properties of reducing software development time and effort by reusing functional service units. The reusability of services can effectively promote through loose coupling between services. But strong associations of object-oriented systems such as inheritance and aggregation create a rather tight coupling between objects. The component-based systems without inheritance and aggregation create a loose coupling between components. Thus components provide service realization at runtime using the functionality provided by their interfaces. Therefore legacy component-based systems need to have service-oriented computing concept in order to support functional service units efficiently. Also, conventional methods for service-oriented computing system have not suggested the clear classification of service layers, the clear service identification guideline introducing service layers and a service mapping method between serviceces of each layer. Therefore we suggest the service classification and the identification guideline of business view and implementation view introducing layers and propose a mapping between two views. That is, we research service layers, service identification, diversified service sizes and a service mapping method between services of each layer. This can be applied to legacy component-based system to extend to the service-oriented computing system.

  • In order to investigate regional variation of food component in the top shells, Omphalius pfeifferi capenteri, caught from Jeju, Sogwipo, Hallim and Songsan, Jeju island, Republic of Korea, food sanitary (heavy metal and volatile basic nitrogen), nutritional (mineral, total amino acid contents, fatty acid composition), taste (extractive nitrogen) components and sensory evaluation (color, texture and taste) were measured. From the result of the contents of heavy metal and volatile basic nitrogen, the top shell might not invoke health risk in using food source, The extractive nitrogen contents of top shell were $343.0\~385.4\;mg/100\;g$. The amounts of total amino acids were $12.5\~13.2\;g/100\;g$, and the major compound among them were glutamic acid, proline and aspartic acid. The major compound among mineral were sodium, calcium, potassium and magnesium. In fatty acid composition, polyenes with essential component or healthy functionality such as 20:4n-6, 20: 5n-3 and 22: 5n-3 were the major components. But, lipid content was extremely small. Judging from the results of chemical and sensory evaluation described a above, food components were not different among top shells caught from various area.

  • Recently software industry in GIS(geographic information system) becomes an interesting issue by performing a large scale of national GIS application development as well as even small unit of FMS(facility management system). Also, there exist many cases to combine GIS with various business domains such as MIS(marketing information system), CNS(car navigation system) and ITS(intelligent transportation system). In this situation, in order to develop an efficient and useful GIS application for a short term, there must be a deep consideration of not only developing GIS component but also managing GIS component. In fact, even though there exist many certain components having high reusability, excellent interoperability and good quality, their reusability may be reduced because of their difficulty to access in a certain repository. Therefore, it is important to classify components having common characteristic based on their particular rule with reflecting their functionality and non-functionality before cataloging them. Here, there are two non-functional classification categories discussed such as GIS content-dependent metadata and GIS content-independent metadata. This cataloged components will help application developers to select easily their desired components. Moreover, new components may be easily producted by modifying and combining previous components. Finally, the original goal of all this effort can be defined through obtaining high reusability and interoperability of GIS component.

  • The purpose of this study is to analyze the thermal characteristics of garments marketed for Korean males and to investigate the influence of each garment on ensemble, by measuring their insulation values(clo) using thermal manikins. The results are as follows. The total insulations(clo) of ensembles for S/S seasons are between 1.46 and 2.6 clo, with the mean of 2.12 clo. The insulation in the still air condition is 1.23 clo, which means a decrease of 42% compared to the total insulation of all the component garments. The insulation of ensembles for S/S seasons in the dynamic air condition decreased by 46.8%, compared to the still air condition. The total insulation(clo) of ensembles for F/W seasons is between 3.84 and 7.36 clo with the mean of 4.74 clo. The insulation in the still air condition is 2.26 clo, which means a decrease of 53.6% compared to the total insulation of all the component garments. The insulation of ensembles for F/W seasons in the dynamic air condition decreased by 36.2%, compared to the still air condition. As the clo value of each component garment gets higher, the insulation of ensembles gets higher. Especially, the insulation of ensembles was more influenced by outer wear than inner wear. The insulation of ensembles could be predicted by the insulation of outerwear better.
