The focused ion beam (FIB) method is widely used to prepare specimens for observation by transmission electron microscopy (TEM), which offers a wide variety of imaging and analytical techniques. TEM has played a significant role in material investigation. However, the FIB method induces amorphization due to bombardment with the high-energy gallium ($Ga^+$) ion beam. To solve this problem, electron beam induced deposition (EBID) is used to form a protective layer to prevent damage to the specimen surface. In this study, we introduce an optimized TEM specimen preparation procedure by comparing the EBID of carbon and tungsten as protective layers in FIB. The selection of appropriate EBID conditions for preparing specimens for TEM analysis is described in detail.

Like all other European countries, as a result of gradual industrialization, Germany is just before the start of new social system; the so-called 'aged society'. Over half of the century, Germany focused their welfare system on facilities. However, with the start of the new 'aged society', they introduced a new concept which consists mainly on home care and community care. These new concepts resulted from the general idea that even elderly have the right to live an independent quality life. Therefore, to satisfy the elderly with such life it has been seen as necessary not only to offer them efficient protection but to introduce an economical welfare system and facility scheme. The regional integration plan for welfare is one of the open schemes in which the lifestyle of the elderly are seen as the whole. Participated by several members and specialists of all social standings, necessary facilities are planned. By looking into a project example carried out in Germany, this study is aimed to increase the quality of the elderly welfare system and facility construction plan.

The colony education policy of Japanese Empire was, as a su n.0, ppression on national salvation education of Korean, on the one hand it was liquidation of Korean national spirit and other hand, it has the object to Japanizing Koreans through cramming Japanese language and its culture. During the Japanse occupation of Korea, the libraries had two roles, one was to press Korean and its culture and the other was to civilize Koreans for Japanizing. The purpose of this study is to examine the role of rural-mini libraries whether the former or the latter. From 1932 to The Chosun Governor- General Department (Chosun Chongdokboo) actively spread 'The Movement of Rural Development in Korea. At the same time there were many rural -mini libraries in Korean rural and fishing community. Under the colony of Japanese Empire, colony policy was itself very tough that Japanese Empire did their utmost ideas to win Korean culture over and Japanzing Korean with every possible pressures. Since rural-mini libraries were planned by the chosun Governor-General Department, however, were established by Korean themselves with the property of local education center( Hyanggyo). Therefore, rural-mini libraries were as facilities to promote rural economic development for providing Japanese with some materials which need to conduct a war, and to introduce local people to participate in civilizing activity themselves and farmers and fishermen were forced to group to be educated in Japanese language and its reading. Rural-mini libraries were, as it were, not as facilities for enlightening Korean peoples but as facilities for civilizing Koreans.

This Study has intended to extract traditional elements for making Korean traditional garden through survey on theexperts and practitioners of landscape architecture. The survey form includes questions about representative type of traditional garden, representative elements of traditional garden, and necessary elements for making traditional garden, etc. The results are as follows; 1) the representative type of Korean traditional gardens are palace and villa gardens. 2) the available traditional facilities should be applicable with contemporary culture only maintaining the original form. 3) the major traditional facilities are water-scape such as ponds and mountain streams with traditional pavilions. 4) plants should be selected in spontaneous plants in Korea but it is possible to introduce species recorded in old documents. It is difficult to suggest the method of layout and design strategies in this study, but continuous studies in this line will be helpful to designing Korean traditional garden suitable in contemporary landscape.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.

This paper will introduce the development case study about virtual-reality-based operation training system for steel making process. Steel making process consist iron making process to create liquid steel, pig iron, by reduction process, steel making process to make molten steel by refining, continuous casting process to make slab, and rolling process to make final product like coil, plate. This steel making process deals with liquid and solid products, so facilities of steel making process are very various and complicated. In addition, according to various customer requirements, the recycle of facilities and recipes changing have been fast. So the training for skilled operators is very important point. In this paper, we develop steel making training system based virtual reality for training skilled operator. This system consists of virtual machine, virtual HMI, and virtual control panel. And for fitting the characteristics of each process and increasing the education effectiveness, we develop dynamic methods like the method of dynamic education system configuration, initial facilities setup operation education system, and etc.

Recently advanced nations utilize evaluation system about LCC, and KOREA begin to introduce the system to reduce construction expense. And Introducing "Technical proposal type bid" that is new government construction order mode made needs for valuation of price to evaluate facilities LCC. These days LCC is evaluated by BTL and turnkey project in KOREA, but it is suffering from difficulty in evaluation. because evaluation element and standard are indefinite. In addition LCC evaluation of public construction business except BTL and turnkey is not consisting. Therefore, in this research we present LCC evaluation Index for systematic and objective evaluation.

This study was aimed at examine eating behavior and food preferences of children in preschool nursery facilities. A survey was conducted on parents using questionnaires including general characteristics, eating behavior, and food habits at home and food preferences of children in 6 nursery facilities. The children involved in this study were 150 boys and 154 girls, aged 1 to 7 years old. Sixty three percent(187 children) of the children were on 'regular' meal times, and 37.0%(110 children) were on 'irregular' meal times. The major reason for their irregular meal times were 'their' concentration on other tasks'(26.6%) and 'no appetite'(25.5%). The meal eaten best by children was 'dinner' while that eaten worst was 'breakfast'. The major type of their eating habit problem was 'unbalanced diet'(62.1%), and their mothers' response to the unbalanced diet was 'trying to persuade the child'(71.6%). The number of snacks at home was one or twice a day(97.3%), and 'preference'(67.8%) was the main reason for selecting particular snacks. Their preferred staple foods were 'cooked rice with meat & vegetables and Chinese noodles', and 'noodles with bean sauce', and their preferred soup was 'seaweed soup' Also, their most preferred meat dishes were 'fried chicken' and 'thin sliced barbecued beef. Children preferred side dishes with animal foods to those with vegetable foods. Since children liked mixed dishes, it seems desirable to introduce foods which children dislike as ingredients in mixed dishes.
