This paper is focused on the traditional sash weaving handicraft of‘She’ethnic group, which is located in Fujian, Zhejiang, Jiangxi, Guangdong province of China. This research is main-ly based on the field work, analyzed and inter-preted the traditional sash in systematic and reasoned way. The summary of this study are as follows : 1. On its technological aspect, weaving structure of the traditional sash is made of warp rod backed weaving. The used tool is primitive one but the weaving process includes scientific method. 2. From the social-cultural point of view, the sash ha been the symbol of love towards her lover. Every woman of this group had taken training for this sash weaving from a child. 3. On its ethnological aspect, it has been long history and has interchanged with other ethnic group like Miao, Han and also Okinawa country of Japan. The pattern inside this sash are almost looks like characters, but they are not Chinese characters whereas are the inde-pendent code of‘She’ group and have been inherent from ancestors and which will be tran-smitted to their posterity. These independent code of‘She’group are the traditional message to their later generation implicating their natural circumstances, human relationship, ethnic myth, spirit etc. 4. I recognize that the pattern inside the sash is defined as the communicative code and in comparison to language, it is more repetition and less apparent as close code. Nowadays China has been developed es-pecially in the economical fields rapidly. Under the circumstances traditional weaving culture of ethnic groups has been facing a crisis of disappearance, which will be a great loss for the country as well as the human beings. For this reason, I emphasize that it is very immediate to make co-researches into the material culture of Chinese ethnic groups.

The B-lymphocyte differentiation from committed B-cell progenitors to antibody-secreting cells was discussed. B-cell progenitors derived from hematopoietic stem cells undergo the rearrangement of immunoglobulin(Ig) gene. The earliest cells as B-cell precursors have cytoplasmic Is(${\mu}$ chain). The entire Is molecule is expressed on the surface after synthesis of L chain. The resting B cells(Go stage) stimulated by binding antigen via Ig-receptors are activated(G$_1$ stage) and followed by proliferation(S stage), coupled with further selection(affinity maturation. class switch). The production of antibody against a particular antigen depends on the activation of B cells with surface Is capable of reacting with that antigen. This process does not occur in isolation but is controlled by helper and suppressor T cells and antigen presenting cells(APC). The mechanism of T cell-dependent B-cell response for production of antibody is largely explained by the cell to cell cooperation and soluble helper factors of T cells. 1) The antigen specific B cells and helper T cells are linked by Is-receptors, leading to the delivery of helper signals to the B cells. 2) Helper T cells recognize the processed antigen-derived peptides with the MHC class II molecules(la antigen) and is stimulated to secrete B-cell proliferation and differentiation factors which activate B cells of different antigenic specificity. The two models are shown currently 1) At low antigen concentration, only the antigen-specific B cell binds antigen and presents antigen-derived peptides with la molecules to helper T cells, which are stimulated to secrete cytokines(IL-4, IL-5, etc.) and 2) At high antigen concentration, antigen-derived peptides are presented by specific B cells, by B cells that endocytose the antigens, as well as by APC Cytokines secreted from helper T cells also lead to the activation of B cells and even bystander B cells in the on- vironmment and differentiate them into antibody-secreting plasma cells.

India is a gigantic market with a population of 1.2 billion and an economy that is growing at the second-fastest pace in the world. The volume of trade between India and Korea has been sharply increased with the increase of dispute since 2000. Although avoidance of disputes is always a priority, it is also important to prepare methods of dispute resolution which are efficient and economical. So, understanding of Indian dispute resolution system is a necessary requirement for successful business operation with Indian companies. This article analyzed and compared with the various ways of Indian ADR such as negotiation, mediation, conciliation, Lok Adalat and arbitration in order to help the Korean traders who enter into business with the Indian companies to settle their disputes efficiently. In conclusion, this article suggests the following ways to overcome problems of dispute with Indian companies: First, the Korean companies should recognize the characteristics of Indian ADR Ways respectively. Second, the Korean companies should utilize the conciliation or the mediation in small claim but arbitration in large claim. Third, Write a contract and insert the KCAB's standard arbitration clause in their contract.

Face recognition system has advanctage to automatically recognize a person without causing repulsion at deteciton process. However, the face recognition system has a drawback to show lower perfomance according to illumination variation unlike the other biometric systems using fingerprint and iris. Therefore, this paper proposed a robust face recogntion method against illumination varition by slective fusion technique using both visible and infrared faces based on fuzzy linear disciment analysis(fuzzy-LDA). In the first step, both the visible image and infrared image are divided into four bands using wavelet transform. In the second step, Euclidean distance is calculated at each subband. In the third step, recognition rate is determined at each subband using the Euclidean distance calculated in the second step. And then, weights are determined by considering the recognition rate of each band. Finally, a fusion face recognition is performed and robust recognition results are obtained.

This paper is on a system design of recognizing sound sources and tracing locations from detecting a section of sound sources which is strong in surrounding environmental sounds about sound sources occurring in an abnormal situation by using signals within the section. In detection of the section with strong sound sources, weighted average delta energy of a short section is calculated from audio signals received. After inputting it into a low-pass filter, through comparison of values of the output result, a section strong in background sound is defined. In recognition of sound sources, from data of the detected section, using an HMM(: Hidden Markov Model) as a traditional recognition method, learning and recognition are realized from creating information to recognize sound sources. About signals of sound sources that surrounding background sounds are included, by using energy of existing signals, after detecting the section, compared with the recognition through the HMM, a recognition rate of 3.94% increase is shown. Also, based on the recognition result, location grasping by using TDOA(: Time Delay of Arrival) between signals in the section accords with 97.44% of angles of a real occurrence location.

3D visualization of geological environments using remotely sensed data and the various sources of data provides new methodology to interpret geological observation data and analyze geo-information in earth science applications. It enables to understand spatio-temporal relationships and causal processes in the three-dimension, which would be difficult to identify without 3D representation. To build more realistic geological environments, which are useful to recognize spatial characteristics and relationships of geological objects, 3D modeling, topological analysis, and database should be coupled and taken into consideration for an integrated configuration of the system. In this study, a method for 3D visualization, extraction of geological data, storage and data management using remotely sensed data is proposed with the goal of providing a methodology to utilize dynamic spatio-temporal modeling and simulation in the three-dimension for geoscience and earth science applications.

The purpose of this thesis is to study the social and cultural background and characteristic of neo-classicism which appered in the modern fashion of the pluralistic society of the latter half of 20th century to understand that the product of societh such as fashion mode reflects the situation of society and culture. For this purpose, documentary studies about the concept and background of neo-classicism, were preceded, and analyzed the occurrence background and characteristic of neo-classicism of the modern fashion after the 1980's, which showed up in post-modernism fashion. The characteristics of neo-classicism expressed in modern fashion is as follows; First, they are expressed in modern fashion in forms of simplicity by means of minimizing process of sewing or ornamenting and deletion of dart. Second, retro-style in terms of concerning of the past, is featured in various styles of Greco-roman drapery and expresed in forms of mixing clothing elements of modern and classic in modern times. Third, the trend of ecology in terms of interest of the nature and the thought that the spiritual world is more important than the material world. It is expressed by using natural elements adn natural materials, which wanted to get the nature and human into one and search for the losed nature of modern men. Fourth, the pursuit of the beauty of the human body, is expressed in forms of body-prioity style through using see-through or elastic materials, which is knit, lycra, spandex, etc. In conclusion, we can recognize that the social product reflects social and cultural situation. And the characteristic of neo-classicism has the meaning of harmonizing the human and nature and the returing the humanity.

This article is a theoretical and empirical study of engineering and gender, and also explores the policy development of WIE program. WIE in Korea aims to foster talented women engineers through the introduction of gender-sensitive engineering education system, field-adaptive skill improvements of women students, and industry-university collaborations. This study examines gender perspectives to analyze our WIE program. It is important to recognize that it's not enough to acquire institutional and structural equity in developing women in engineering. Above all, we should note our situations that has frustrated women's career development in engineering. In university education, we need to improve the engineering faculty's recognition of gender equity. Efforts to establish the professional identity of women engineers, involvement of men and women students, and building of women engineers' network are necessary elements to implement successful WIE program. Additionally, we discuss that policy support to WIE program should be continued and enlarged in university level.

This study is tried in order to link informal arithmetic reasoning to formal algebraic reasoning. In this study, we investigated elementary school student's non-formal algebraic reasoning used in algebraic problem solving. The result of we investigated algebraic reasoning of 839 students from grade 1 to 6 in two schools, Korea, we could recognize that they used various arithmetic reasoning and pre-formal algebraic reasoning which is the other than that is proposed in the text book in word problem solving related to the linear systems of equation. Reasoning strategies were diverse depending on structure of meaning and operational of problems. And we analyzed the cause of failure of reasoning in algebraic problem solving. Especially, 'quantitative reasoning', 'proportional reasoning' are turned into 'non-formal method of substitution' and 'non-formal method of addition and subtraction'. We discussed possibilities that we are able to connect these pre-formal algebraic reasoning to formal algebraic reasoning.
