최근 들어 국제 방사선 방호위원회(ICRP: International Commission on Radiological Protection)의 ICRP-60에서는 원전 작업종사자의 연간 허용 피폭량을 현행값인 5 rem보다 연 평가 2 rem으로 제한 운영토록 권고하고 있다. 이렇게 엄격해지는 방사선 관리규정에 능동적으로 대처할 수 있도록 새로운 방호차원에서 관련 계통 및 기기들의 방사선량을 낮출 수 있는 기술 개발이 절실한 실정이다. 각국의 원전에서는 방사능을 강구하고 있는 실정이다.(중략)

Rem Koolhaas has pursued new architectural approaches breaking with conventional ones. Around the 1990s when large-scale projects occurred with the union of Europe ahead, Koolhaas recognized the limits to the existing methods for responding to such changes. Accordingly, he came to use design methods based on 'congestion' and 'void' as strategical alternatives, which became the moment for him to leap forward from the previous working sphere based in Europe to becoming an architect who would be commissioned a number of large-scale global projects. Therefore, this study intends to investigate his design methods which utilized congestion and void, and to derive spatial characteristics from the projects based on such methods. First of all, the study looked into the historical background, definition and process of congestion and the void as design methods, and analyzed his projects to which such methods were applied by classifying them into the following categories: 1) the void that removes a space of singularity; 2) the void that penetrates space while making a flow; and 3) the void that is formed by vertical extrusion. Then, the characteristics of architectural spaces made in this way were identified as 1)the single-body appearance made by congestion and the following types of space made by the void: 2) the non-uniformly shaped space that looks like floating; 3) the flexible space with various flows and directions; and 4) the space with virtual possibilities that embrace contingent events. This understanding of Rem Koolhaas's design methods which were attempted in various ways at his critical turning point will be the foundation to understand the overall world of his works.

Recently, significant tries appeared in the spatial design field were appreciated as tries to find crossing between space formation and discourse. This study is to find spatial clues from Gilles Deleuze, the modern philosopher's literature where he developed his discourse analyzing paintings of Francis Bacon, and reveal common characteristics with the contemporary spatial design. According to the analysis of Deleuze, Bacon's paintings are separated into frame-aplat, shape-figure, and contour-track. From these three elements, I extracted spatially analyzing languages of 'occurrence of shape-accident', 'space of track-sense', and 'interaction of aplat-background.' Then with these analyzing languages, I analyzed latest works of Rem Koolhaas. Deleuze Space Theory confirmed in works of Rem Koolhaas is the application of accident-focused occurred between the user and space, the space that induces accident, and differentiation between the user and space or space and site. As a result, I could confirm the common characteristic that both modern discourse and spatial design are understood as 'difference' from life and movement.

This study analyzes the place of modem architecture based on the place theory of C. N, Schultz. For applying Schultz's theory to the modern architecture, It is required to examine the modern cityscape, features of inner space of architecture and features of program. By analyzing the avant-garde architecture of Rem Koolhaas on such basis, the potentiality of placeness of modern architecture could be verified and the alternatives would be searched. It is inferred that the placeness features of Rem Koolhaas' public architecture is under the influence of the interpretation of program based on the humane background rather than the physical aspects of surroundings. The inner space shows the non-linear features, the metaphor of city. The obscurity of physical boundary illustrates the flexible features with ambiguous boundary. Consequently, the inner space expresses the surreal atmosphere that doesn't match the purposes of usage of architecture, the traditional concept. The outer shape is recognized as the by-product from the interpretation of internal program rather than it considered the surrounding context. The outer shape has the relatively simple formative shape and contrasts against the complicated inner space by using the non-physical materials. It is found that Koolhaas' architecture doesn't pursue the features of placeness of traditional concept. However, It is inferred that his architecture has the possibility of placeness by attaching the meaning through the social roles of each architecture. It gives the substantial suggestion to the modern architecture that can't easily acquire the placeness of traditional concept due to the environment of modern city.

Today, the views on Temporality of space have been changed not only to be based on the concept of time, but also to identify the space with a body adapted to the new circumstances. The study suggests that the actions of performers in space have been important by changes of views and are connected to the music phenomenology mixed with music whose tempo is the phenomenology related with of human consciousness itself, and derives the temporal property by putting them into Rem Koolhaas space with the fluid quality. According to Clifton's Phenomenology of Music, an understanding of music is made in both human body and consciousness as two ways to listen to sounds and enjoy music. Though a correlation between the characteristics of Clifton's Phenomenology of Music and one of resulted from uncertainty and immateriality of modern space Temporality, we could work out four kinds of characters which are the continuity of the fluidity from temporal programs, contrasting changes or synchronicity, the multidimensionality from synesthesia of line and face, ventilation by quality of the material and immaterial circumstances of sound effects, the implication in events resulted from cognition for information and unexpected actions, and the autonomy of the route of a variety of experiences including intimate connection of inter-related events and temporary and diverse external conditions. Hereby Temporality of musical phenomenology in Rem Koolhaas's space can be experienced by systems base oh the importance of host's motion, changes of programs according to the motion as well as uncertainty and immaterial changes. Due to the changes user's emotion and motion is undergone as Temporality that changes automatically.

Objectives: This study was performed to review the research trends in treatment for REM sleep behavior disorder (RBD) in Traditional Chinese Medicine (TCM) and Kampo in Japan. Methods: We searched articles in CNKI (China National Knowledge Infrastructure) under the key words, "RBD", and Chinese words related with it in Traditional Chinese Medicine, Traditional Chinese Medicinal Herbs and Combination of Traditional Chinese Medicine With Western Medicine' field, and also in CiNii (Citation Information by NII); we also searched articles in Kampo Square in Japan under the key words, "RBD" and Japanese words related with it. We found 10 papers, and then selected 6 of them except the non-clinical and unrelated studies. We then analyzed their way of diagnosis, treatments, study type and etc.. Results: 6 studies were divided into 4 case reports, one control study, and one literature review study. All of the studies reported that Herbal medicine for RBD was effective as much as Western medicine like clonazepam and paroxetine. However, the quality and the quantity of these clinical studies were not enough. Conclusions: It seems that the researches for RBD have gradually been performed in TCM and Kampo. We hope that our study can activate/push forward clinical research for this disorder in Korean traditional medicine.

The present investigation was performed to evaluate the homeostatic regulation of sleep architecture by the ethanol extract of Korea red ginseng (KRG), since the available data were often controversial. In addition, it was also interested in whether the sleep-wake stages were differently affected by low and high doses of KRG. Each adult Wistar male rat was implanted with a transmitter for recording EEG and activity via telemetry. After one week of surgery, polygraphic signs of undisturbed sleep-wake activities were recorded for 12 h (between 9:00 am and 9:00 pm) after KRG administration. KRG (10 and 100 mg/kg) increased non-rapid eye movement (NREM) sleep as well as total sleep. The total percentages of wakefulness were decreased comparably. KRG (10 mg/kg) decreased the power density of the ${\delta}-wave$ (0.75-4.5 Hz) and increased ${\alpha}-wave$ (8.0-13.0 Hz) in the NREM and rapid eye movement (REM) sleep. KRG also decreased ${\delta}-wave$ power density in wake time. However, KRG (100 mg/kg) increased ${\delta}-wave$ and decreased ${\theta}-wave$ (5.0-9.0 Hz) power density in wake time, while showed little effect on the power density in NREM and REM sleep. In conclusion, low and high doses of KRG increase spontaneous sleep and NREM sleep and differently regulate the EEG spectra in REM and NREM sleep.
