It is necessary to understand a self-expression and communication in cyberspace using digital photography We have studied the digital camera consumer's self-expression and communication skills and strategy through ethnographic interviews. In this study, we have used ethnographic interviews of 7 informants who had personal web site and are using digital cameras. As a result, It has turned out that informants expressed their self taking pictures of their daily life, friends, and family. Also they imply meaning and feeling in the pictures that had been taken to express their lives. The communication in cyberspace has turned out that informants communicate with other people with digital pictures to show their life. They communicated each other and give information. It means that they made information by themselves to give and share with other people as prosumer. Digital photography to express themselves and communicate in cyberspace enhanced human relationship that had made in cyber space. And it helps to form their self identity. They express their cyber identity with digital photography and it is similar to their self identity that expresses in real life.

There are several reasons to take X-ray in case of inpatients. Some of them who cannot ambulate or have any risk if move are taken portable X-ray at their wards. Usually, in this case, many other people-patients unneeded X-ray test, family, hospital workers etc-are indirectly exposed to X-ray by scatter ray. For that reason I try to be aware of free space scatter dose accurately and make the point at issue of portable X-ray better in this study. kVp dose meter is used for efficiency management of portable X-ray equipment. Mobile X-ray equipment, ionization chamber, electrometer, solid water phantom are used for measuring of free space scatter dose. First of all the same surroundings condition is made as taken real portable X-ray, inquired amount of X-ray both chest AP and abdomen AP most frequently examined and measured scatter ray distribution of two tests individually changing distance. In the result of measuring horizontal distribution with condition of chest AP it is found that the mAs is decreased as law of distance reverse square but no showed mAs change according to direction. Vertical distribution showed the mAs slightly higher than horizontal distribution but it isnt found out statistical characteristic. In abdomen AP, compare with chest AP, free space scatter dose is as higher as five-hundred times and horizontal, vertical distribution are quite similar to chest AP in result. In portable X-ray test, in order to reduce the secondary exposure by free space scatter dose first, cut down unnecessary portable order the second, set up the specific area at individual ward for the test the third, when moving to a ward for the X-ray test prepare a portable shielding screen. The last, expose about 2m apart from patients if unable to do above three ways.

The present study investigated the actual conditions of physical therapy rooms at long-term hospitals in Korea and conducted a comparative analysis to develop an efficient floor plan and facility improvement measures. 1. At hospitals surveyed, physical therapy services were used at a high frequency but they did not have enough space for rehab treatment and long paths of patient flow were found to make patient management inconvenient. Therefore, physical therapy units should be conveniently located both in terms of distance and direction so as to be accessible from patient rooms or wards. The space should be organized in a concentrated layout for efficiency of physical therapy, and floor planning for therapy units should ensure the best possible viewing angle to therapists. 2. With regard to the disease characteristics of patients, many physical therapy rooms were in difficult circumstances because of poor facilities, so they need to secure skilled personnel, supplement apparatuses and equipment and have rooms for functional recovery, hydrotherapy and operation treatment. In addition, each of the curtained or partitioned areas for treatment should be set up with consideration for the amount of space taken up by medical equipment. The area under each bed should be designed for patient convenience so that it can be used as storage space for patient's belongings and shoes. 3. Patients complained about the lack of physical therapy space, resting places or exercise areas and demanded the expansion of rehab programs and facilities. Physical therapy facilities need to be improved for patient privacy and effective natural ventilation. 4. At most of the long-term hospitals surveyed, physical therapy units were found to have small areas and treatment equipment and devices were insufficient compared to the number of patients. Therefore, it is required to secure more space (at least 138.24 sq. meters per 100 beds) and improve facilities for better physical therapy services.

"Urban traditional housing" means a type of urban housing which retains characteristics of traditional Korean houses for ordinary people. It is a form of housing created in the process in which traditional Korean ways of life are applied to swift modernization. In Korea's traditional housing, the "court" functioned as a living space that promoted family bonding. The space of the court still remains in the urban traditional housing. However, rapid popularization of the westernized housing form, i.e., apartments, resulted in standardization and westernization of our housing and living patterns, and as a result, the court in urban traditional housing came to lose its original meaning. The objects of this study are residents of urban traditional housing. By studying them, this research aims, firstly, to understand the meaning of the inner court, secondly to analyze correlation between the residents' consciousness of the inner court and their use of the space, and ultimately to find various possible forms of our future housing. For this research, twenty six houses in the Gahoe-dong area in which urban traditional houses are densely built up were investigated. According to the result of this research, the inner court in current urban traditional housing is a space existing inside a house but directly exposed to outer air at the same time. It is a private but shared space. It contributes to forming a pleasant atmosphere by facilitating ventilation and providing sunlight. In addition, it is a living space that actively reflects the Korean living style that values family life.

The importance of communication which is oriented to interaction, fusion and connection is more increased in the post-information society. The information environment is already realized as interface to reach immediately and freely to the databased information and knowledge. The contemporary libraries execute very important roles as an intellectual infra of modern times to deliver the great human achievement and create new culture. In the mean time, the rapid information-oriented society and the development of digital technology bring out big change in the traditional dispatch and receipt method of information. For this reason, libraries as the community space of visitors integrates physical space - electronic space and reconstructs new temporary culture and value to build the new interface that connects human to human, human to space and human to information. On the premise of these awareness, this study analysis the creative interface factor of Tama Art University New Libraries in Ito Toyo in order to research the function and the application method of modern libraries. And the results are follows. 1)We can make sure the significance of communication and the integration consciousness between digital technology and analogue sensitivity that is the characteristic of the post-information society. 2)We can classify for the creative interface factors by the character as space factor(Arcade, Gallery, Lounge, AV Booth, Cafe), facility/equipment factor(Laboratory, Media, Bar, Info Shelf, Media Seat) and furniture factor(Carrel, Desk, Mag Table, XI Shelf). 3)We can see that these interface factors change the stream of library users and that the library is constructed for library users to create and discovery something easily from books and modern technologies. And we can realize also that these factors are creative installation to lead out naturally the latent liberty sense of users.

정지궤도급 차세대 통신위성에 탑재될 디지털신호처리기에는 디지털 고속통신을 위한 FPGA가 사용된다. 적용된 FPGA는 높은 열소산량을 가지고 있으며, 이로 인한 접합온도의 상승은 부하경감 요구조건을 만족하기 어렵고 장비의 수명과 신뢰도 저하의 주요 원인이다. 지상과는 달리 우주환경에서의 전장품의 열제어는 대부분 열전도를 통하여 이루어지고 있다. CCGA 또는 BGA 형태의 FPGA는 인쇄회로기판에 장착되지만, 인쇄회로기판의 열전도율은 FPGA의 열제어에 효율적이지 못하다. FPGA의 열제어를 위하여 부품 리드와 하우징을 직접 연결하는 히트싱크를 제작하였으며, 우주인증레벨의 열진공시험을 통하여 그 성능을 확인하였다. 높은 전력소모량을 가진 FPGA는 우주환경에 적용하기 어려웠으나, 히트싱크를 적용함으로써 부하경감 온도 마진을 확보하였다.

본 논문에서는 위상 공간 분석을 통해 3D 벡터 필드를 표현하는 방법을 제안한다. 이 방법은 상미분 방정식과 벡터 필드 위상과의 연결에 기초를 두고 있다. 위상 공간 분석은 위상 공간 형태의 자율 방정식 시스템의 기하학적 보간법이 되어야 한다. 이 방정식 시스템의 모든 해는 공간에서의 곡선이 아니라 곡선을 따라가는 점의 움직임과 일치한다. 이러한 분석은 이 논문의 기반이다. 새로운 방법은 3차원 벡터필드에서 육면체 셀을 5 또는 6개의 사면체 셀로 분해하는 것을 요구한다. 임계점은 각 사면체의 간단한 선형 시스템을 풀어서 간단하게 구할 수 있다. 각 사면체의 일반해에 의해 그려지는 전체 곡선과 사면체의 한 면을 포함하는 평면과의 교차점을 계산함으로써 탄젠트 곡선은 구해진다.
