The observation of the new biotite isograd (chlorite + chloritoid = andalusite + biotite) in the Mungyong coal field requires the modification of Harte and Hudson's (1979) metapelite grid which eliminates the stability field of staurolite + cordierite assemblages. The newly proposed metapelite grid by Ahn and Nakamura (2000) can define more properly the isograd reaction observed from nature. We discuss first topological interrelations between synthetic system (FASHO-, KFASHO-, KFMASH system) on an isobaric section at 2kbar, where phase relations are well constrained. The following discussion is concentrated on the topological relations between stable reactions. At the last, we discuss the petrogenetic significance of the Ahn's petrogenetic grid compared with theoretically computed grids. Ahn's petrogenetic grid is consistent with synthetic and natural system, and is one of the excellent example of KFMASH approximation in metapelite.

Amplification based on empirical relations is widely used for seismic microzonation of urban centers. Amplifications are used to represent the site effects of a particular soil column. Many empirical correlations are available to estimate the amplification of seismic waves. These correlations are based on the ratio of shear wave velocity of foundation/rock to soil velocity or 30 m equivalent shear wave velocity ($Vs^{30}$) and are developed considering deep soil data. The aim of this work is to examine the applicability of available amplification relations in the literature for shallow engineering bedrock sites by carrying out site response studies. Shear wave velocity of thirteen sites having shallow engineering bedrock have been selected for the study. In these locations, the depth of engineering bedrock (> 760 ${\pm}$ 60 m/s) is matched with the drilled bore hole. Shear wave velocity (SWV) has been measured using Multichannel Analysis of Surface Wave survey. These sites are classified according to the National Earthquake Hazards Reduction Program (NEHRP) classification system. Amplifications for an earthquake are arrived for these sites using empirical relations and measured SWV data. Site response analysis has been carried out in SHAKE using SWV and using synthetic and real earthquake data. Amplification from site response analysis and empirical relations are compared. Study shows that the amplification arrived using empirical relations does not match with the site response amplification. Site response amplification is much more than empirical values for same shear wave velocity.

According to the passage of an age, a method which communicates each other between the city and space, and space and a human has changed. Recently, as the city is developing related with the public, the sphere and a territory of activity of a public has been wider in an environment of the city. Therefore, development of night scenery and the rise of a medium of a vision are accompanied with a new material and the high-technology. Innovation of abundant techniques tends to being surface and mass media, and breaks from the architectural aspect of space as mutual expansion of relations between interior and exterior, and making a boundary obscurely. Space design represents peculiarity of non-territorial which modern art, an advertisement, a media and a reflection are integrated as getting over above tendency. As we find out methods which the public can communicate with the space in wider territory, the public and the space can extend mutual relations and the design of modern space is been varying a part as the space which has a context of city and synthetic sociality for the public by avoiding independent objects.

청소년기는 가족관계를 통해 1차적 사회관계를 경험하는 시기이기 때문에 청소년의 가족관계는 매우 중요하다. 특히 사회복지서비스를 제공받고 있는 조손가족 청소년은 일반 청소년에 비해 부정적인 가족관계로 인한 심리·사회적 문제를 일으키는 경우가 많아 그들의 가족관계를 완화하여 다시 회복할 수 있는 적응유연성이 필요하다. 본 연구에서는 조손가족 청소년의 가족관계가 적응유연성에 미치는 영향에 있어 자아존중감, 공감, 내·외통제감을 매개변수로 설정하였고, 그들 간의 경로를 파악하여 전체적인 측면에서의 통합적인 인과성을 밝히고자 하였다. 이를 위해 전국 단위의 조손가족 청소년 492명을 대상으로 Amos 19.0 프로그램을 이용하여 상관관계 및 경로분석을 실시하였고, 모형의 유의성 및 경로 간의 직·간접효과의 통계적 유의성을 검증하였다. 분석 결과, 조손가족 청소년의 가족관계는 적응유연성에 직접적인 영향을 미쳤고, 자아존중감, 공감이라는 매개기능을 통해서 간접적인 영향력이 상대적으로 높아짐을 확인할 수 있었다. 이를 통해 조손가족 청소년의 가족관계에 있어 자아존중감, 공감, 내·외통제감에 초점을 맞춘 사회복지프로그램 개발과 활용이 사회복지실천적 접근과제임을 제안하였다.

Through this study I would like to examine the meaning system of the symbolized codes related with real costume figures of the abstract concept of the style of the mourning ceremonial dress in Chosun Dynasty as a variable cause of communication through non-language method by the structural analysis of coding of the ceremonial dress style and the meaning system of the codes centering on the traditional book of funeral etiquette dealing with hueneral cereony in the period. To achieve this purpose, I have used the symbolic theory of constructive concept by F. de Saussure, cultural notation theory of Roland Barthes & Umberto Eco, and structural style of costumes by Myung-Sook Han. The result of the study is as follows. 1. As Chosun Dynasty was a society in which people considered courtesy so much important and practiced the basic Confucian ideas of the three bonds and five moral disciplines in human relations, the characteristic of funeral rites in Chosun Dynasty consists in expression of the thoughts of moral ethics & relative systems and systems of clan rules, etc which was a langue determining the symbols of mourning ceremony dress because the mourning ceremony dress in the period should have the feature of a langue. The mourning ceremonial dresses in the period had five grades of the consume and the grades were determined to be classified into five levels according to the clan system of the chief mourner with sang, ha bang. And the method of the association of the mourning ceremonial dress codes had the six principles of Chinchin, Jonjon, Myoungboon, Chulip, Changyu, and Jongbok. 2. Regarding the mourning ceremonial costumes in Korean society, the meaning of funeral ceremony was expressed by the signifier and materials of the mourning costumes in the society. During the process of the funeral, the intangible feeling of condolence was the expression of mourning and the tangible mourning ceremonial dress was the signal with the lamentation meaning. Especially, characters and patterns were removed from the mourning ceremonial dresses in spite of their function of symbols and the styles of costumes were emphasized. Especially the meaning of condolences was symbolized by attachment of some small pieces of cloth on the upper garments. Hemp was mainly emphasized to be the material of the costumes and some different meanings showed according to the quality of the material hemp. The mourning ceremonial dresses were distinguished from ordinary dresses, which were emphasized because they gad some symbolic meaning of the mourning. 3. Considering the association of the synthetic relations of the costumes from the viewpoint that the mourning ceremonial dresses would be classified according to a system, the symbolization of them were avaliable by sex according to how to combine them and there were no distinction between social classes in the society.

When designing a gear drive, designers should specify tolerances reasonably considering accuracy, cost, and manufacturing capability. In field design, however, designers mostly assign adequate tolerance without correlations between parts and assembly, resulting in iterative design dependent on experts know-how. In order to resolve this, the tolerance design system for a cylindrical gear drive is developed both to support tolerance design automation and to synthesize design processes of part and assembly tolerances. In this research, part tolerances are designed with the databases constructed by ISO, Ks, JIS and bearing catalogue, Assemble tolerance, that is, backlash tolerance is designed by synthesizing part design tolerances stochastically using the formulated assembly relations. This system can include part tolerance and fitting accuracy of shaft adn bearing in practical design. In addition, this system provides field-designers with a synthetic guideline for tolerance design of a gear drive.

In this paper, a rheo-optical methodology based on small angle light scattering and polarimetry is applied to investigate in-situ and on a time resolved basis the flow-induced structures in aqueous biopolymeric blends. Water-dextran-gelatin is chosen as an example. It is verified to what extent the laws and scaling relations, originally developed for synthetic polymer blends, are valid for the morphology development in this aqueous biopolymeric mixture. It was observed that under low shear rate conditions, the biopolymeric emulsion can be regarded as a conventional emulsion. However, at high shear rates flow induced homogenization occurs.
