A museum architecture has been developed as important representation of a specific period in architectural history. Modern concept of museum architecture has started by Karl Fredrich van Schinkel(1781-1841) through das Altes Museum(1823-1830) back in early 20th century and it continues to be the model for museum architecture for over 30 years. By middle of the 20th century, the movement of redefining new model for the new era on the subject of museum architecture was developed. This development was lead by the three masters of the modern architecture at the time. F.L. Wright, Corbusier, Mies and they were responsible and very active in creating new concepts. Their works in museum design became the prototype and they tried hard to make sure their new concepts to be the stepping stone for further development. This study is to compare the three different museums designed by those masters of the modern architecture, particularly on the issue of the exhibition spaces. The purpose of the study will be focused on the point of interior architecture such as the matters of layout and design characteristics of the exhibition spaces. And it will reveal the impact made by those masters on the advanced development of the current generations of museum designers as well as to describe the prototype of exhibition space. The analyzation was done on FLW's Guggenheim Museum in New York, Corbusier's the National Museum of Western Art in Tokyo, and Mies' Die Neue National Galerie in Berliv. Comparable materials were collected through site visits and reference documents from various publications. It will be ideal if this study can be used for further development in new museum design in this country.

Although Frank Lloyd Wright represents himself as one of the greatest American master architect, the master architects contribution towards the advancement in the modern history of architecture goes beyond just creating landmark buildings. Through out his life, he was the leading architect not only in the area or architectural design but showed his talent in interior architecture, furniture, fabric, lighting fixture, art glasses, tablewares, silver wares as well as in graphic design which should cover all the elements related to the "total design" in architecture. As seen in his architectural design, the "total design" concept also reflects both beauty and logic of the nature and strengthens his theory of the organic architecture design. The research began with finding out the relationship between his architecture, nature and the supporting design elements mentioned above. the purpose of the research is to analyze the relationship of the spatial organization and the design elements in Frank Lloyd Wrights architectural works from the point of "total design" view and provide the valuable guide line for the development of the modern interior design. His design theory, based on the fundamental ideas of the nature, his organic architecture design, and reference materials to support total design concept will be discussed on chapter 2. And on chapter 3, application of the total design in his actual project will be analyzed. The data and analyzation have been completed based on written references and actual visit to the project sites. Frank Lloyd Wright placed highest value on the human beings and enjoyed presenting new ideas and forms to create better environment for the humans through his architecture and interior design projects. While he was presenting new ideas he continued to support design for democracy which has close relationship to the new frontier spirit of America. He was the master architect for the general society with accurate understanding of the life style of the public with design sensitivity shown in his concept of the total design.s concept of the total design.

This study is concerned with the process of development and architectural characteristics of secular stained glass in the 20th century. Stained glass had been architectural art from the origin. But it had declined since the Renaissance era, and began to revive in the early 20th century. Stained glass work is very flourish in Korea today, but it is still treated as simple decoration or 2-dimensional mosaic. Architect and interior designer even have little understanding of architectural character of stained glass. In order to recover the architectural nature of stained glass, I have considered the process of development of secular stained glass in the 20th century, and analysed the works of Frank Lloyd Wright, the postwar German artists, Georg Meistermann, Ludwig Schaffrath, Johannes Schreiter, and English artist, Brian Clarke. Major findings of the study are as followings : First, stained glass has come to life again from the secular glass painting decoration in the end of the 19th century, through Art-Nouveau, De Stil, Bauhaus in the beginning of the 20th century, and L'Art $Sacr\acute{e}$. Second, Frank Lloyd Wright, the postwar German artists and Brian Clarke have established the architectural concept and potentiality of the modem stained glass in the secular field. Third, They have done by coming back to the basic creative method by traditional lead-came technique in spite of the development of various materials and techniques. Forth, stained glass fundamentally has architectural characteristics as the characters of Space, Time, Place, Context, and they have showed the new possibility of stained glass by recovery of these characters.

This work continues a trend of developments aimed at exploiting the physical layer of the open systems interconnection (OSI) model to enhance wireless network security. The goal is to augment activity occurring across other OSI layers and provide improved safeguards against unauthorized access. Relative to intrusion detection and anti-spoofing, this paper provides details for a proof-of-concept investigation involving "air monitor" applications where physical equipment constraints are not overly restrictive. In this case, RF fingerprinting is emerging as a viable security measure for providing device-specific identification (manufacturer, model, and/or serial number). RF fingerprint features can be extracted from various regions of collected bursts, the detection of which has been extensively researched. Given reliable burst detection, the near-term challenge is to find robust fingerprint features to improve device distinguishability. This is addressed here using wavelet domain (WD) RF fingerprinting based on dual-tree complex wavelet transform (DT-$\mathbb{C}WT$) features extracted from the non-transient preamble response of OFDM-based 802.11a signals. Intra-manufacturer classification performance is evaluated using four like-model Cisco devices with dissimilar serial numbers. WD fingerprinting effectiveness is demonstrated using Fisher-based multiple discriminant analysis (MDA) with maximum likelihood (ML) classification. The effects of varying channel SNR, burst detection error and dissimilar SNRs for MDA/ML training and classification are considered. Relative to time domain (TD) RF fingerprinting, WD fingerprinting with DT-$\mathbb{C}WT$ features emerged as the superior alternative for all scenarios at SNRs below 20 dB while achieving performance gains of up to 8 dB at 80% classification accuracy.

Today, people are bombarded with information, high-technology and multimedia. With that in mind, museum can no longer attract visitor with traditional concept, so it must find some solution or stimulation to attract their attention back. New museum is becoming a experimental space for new culture, new education, and most of all a place to fulfill one's satisfaction of life. Over the past centuries, Guggenheim Foundation has done a great job in providing place for art and place to get emotional stimulation. Out of all of their museums, Frank L. Wright's Solomon R. Guggenheim in New York and frank O. Gehry's Guggenheim Museum in Bilbao had most unique character yet share similar feature to be recognized as the architectural landmark of the 20th & 21st century Although there are close to 50 years of gap between two museums, their unique, attractive, site-specific, emotional value comes from the two most innovative architect of the past and present century. For Wright the Guggenheim was his last project but it had one of the greatest impact on his career and for Gehry the museum gave him confidence that anything is possible. This study will focus on the spatial organization as well as the architectural formation of both museum to compare and analyze. The goal of the research is to give fundamental data which will reveal emotional elements as well as concepts from each work. The content of this research will mainly focused on their architectural philosophy and it will reveal their concept on human emotion as well as the characteristics of the spatial organization. The result of the study will be a valuable reference for people designing art & cultural facilities in the future.

The aim of this study is to analyze the organization of ithe internal space of Usonian houses that were designed by Frank Lloyd Wright between the 1930s and the 1950s. The Space Syntax Program was used to analyze spatial structure of these Usonian houses. The research range has been done on 9 case studies of Usonian house floor plans, which were designed from the 1930s to the 1950s. The shape of unit floor plans of Usonian house are usually in various L types, - types and transformed types etc.. The research results are as follows : 1) The service space(Kitchen etc.)is located at the center of house and it plays a role in separating the private space(bedroom etc.) and public space(living room etc.). 2) All of the bedrooms of Usonian houses have common characteristic : they are connected by a galley(corridor). 3) The organization of the inside space of most of these houses showed a tendency segregation space. 4) The galley inside space of Usonian house is the most integrated space in the house 5) The living room of the 1930s houses was analyzed as segregation space but it of 1940s and 1950s houses was analyzed as integration space 6) Although bedrooms are connected by galley, which is the highest integrated space of the inside space, this space is analyzed as a segregated space.

생체적합성 천연재료 중 하나인 탈미네랄화된 골분 (demineralized bone particle, DBP)은 골형성단백질 (BMP)을 함유하고 있어 골수간엽줄기세포 (BMSCs)의 분화를 유도한다. 본 연구에서는 DBP를 함유한 폴리 락타이드 (PLA)와 락타이드-글리콜라이드 공중합체 (PLGA) 다공성 지지체를 용매 캐스팅/염추출법으로 제조하였고, 수은다공측정계 및 전자주사현미경을 이용하여 특성결정 하였다. BMSCs는 골분화 배지를 이용하여 조골세포로 분화시켜 Wright-Giemsa, Alizarin red, von Kossa 및 ALP 염색으로 확인하였다. DBP가 함유된 지지체와 DBP가 함유되지 않은 지지체에 BMSCs를 파종한 후 면역결핍 누드마우스의 피하에 삽입하여 이들의 골형성 정도를 비교하여 보았다. 제조한 지지체의 다공도는 $90.2\%$ 이상이었고 평균 다공크기도 69.1$\mu$m 이상이었다. BMSCs는 Wright-Giemsa, Alizarin red, von Kossa 및 ALP 염색결과 조골세포로 분화가 가능했으며, 동물실험을 수행한 결과 DBP가 함유된 지지체에서 칼슘침착 영역을 확인할 수 있었지만 DBP가 함유되지 않은 지지체에서는 칼슘침착 영역을 확인하지 못하였다. 결론적으로 DBP를 함유한 지지체에서 DBP와 BMSCs가 골형성에 중요한 요인으로 작용한다고 사료된다.
