<P><B>Purpose</B></P><P>To compare the physical characteristics of detrusor overactivity (DO) induced by intravesical infusion of saline in awake, sham rats and rats with chronic spinal cord injury (SCI), by simultaneous registrations of intravesical and intraabdominal pressures.</P><P><B>Methods</B></P><P>Male Sprague-Dawley rats, normal or with a spinal vascular clip at the level of Th9, were investigated cystometrically 1 and 4 weeks after SCI. Intravesical pressure (IVP) and intraabdominal pressure (IAP) were recorded simultaneously to evaluate true DO. During the filling phase, the event of IVP rises, defined as increments that exceeded 2 cmH<SUB>2</SUB>O from baseline, were determined as DO according to the absence of simultaneous changes in IAP.</P><P><B>Results</B></P><P>All SCI rats exhibited DO during the filling phase, which was not shown in sham rats. The frequency and pressure of DO had a tendency to decrease with time. The DO frequency of SCI rats after 4 weeks (0.9±0.2 min<SUP>-1</SUP>) was decreased compared with that after 1 week (2.1±0.4 min<SUP>-1</SUP>; P<0.05). The DO pressure of SCI rats after 4 weeks (8.4±1.9 cmH<SUB>2</SUB>O) was decreased compared with that after 1 week (11.6±2.9 cmH<SUB>2</SUB>O; P>0.05).</P><P><B>Conclusions</B></P><P>Cystometric studies in awake male SCI rats showed some significant changes in bladder function after SCI. All SCI rats exhibited DO during the filling phase, and showed different physical characteristics of DO over the course of time. The neurological basis of these time-related changes remains poorly understood, but may provide important prognostic information about long-term urological management in SCI patients.</P>

The microcomputer control of a brushless do motor without a shaft position sensor is implemented. The motor produces a trapezoidal back EMF voltage. The control system is operated by two phase feeding. In the two phase feeding mode, it is possible to obtain the rotor position data from the terminal votage which is not conducting. Microcomputer reads the positon data from the terminal voltage and output the data to the inverter control module. Experimental results show that this system is application to the low power drives of less than one hp for low performance such as fan, pumps and fome appliances.

This study carried out in order to investigate the most basic elements of suitability selection methods for composition of artificial reef. Acquired data by in-situ measurements and satellite remote sensing analysed in applying GIS. To identify the characteristic of marine environment around the West Sea, the South Sea and the East Sea of Korea, physical conditions-seabed sediment and depth, biological conditions-chlorophyll-${\alpha}$, chemical conditions-Sea Surface Temperature(SST) and DO were used. Suitable sites for artificial reef are selected Taean Peninsula, Geoje, Wando, Pohang, Seocheon, etc. From now on, it will be helpful to effectively utilize artificial reef as well as construct synthetic database. It is also expected to use basic data for artificial reef facilities management. 본 논문는 인공어초 조성의 가장 기본적인 요소인 적지선정을 위한 방법에 대해 고찰하였다. 현장관측과 위성 원격탐사(Remote Sensing, RS)로 획득한 자료를 지리정보시스템(Geographic Information System, GIS)을 활용하여 분석하였다. 한반도 주변해역의 해양환경 특성을 파악하기 위해 물리적 조건-해저저질, 수심, 생물적 조건-클로로필-${\alpha}$, 화학적 조건-해수온, DO를 활용하였다. 인공어초 적지로는 태안반도, 거제, 완도, 포항, 서천 등이 나타났다. 향후 본 연구는 인공어초 설치의 효율적인 활용뿐만 아니라 종합적인 데이터베이스의 구축에 도움을 줄 수 있을 것이다. 또한 인공어초 시설관리의 기초자료로 활용할 수 있을 것으로 기대된다.

Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

Recently, the interior design, closely related to architectural trends, has been identified its speciality as a prefession, and increasingly extended into scopes. Therefore, those circumstances make us redefine it's essential points and theories of interior design. It accordance with those contexts, for redefining principles of spatial composition in contemporary interior design, and proposing the direction of it's development, this paper examined how the designs of neo-constructivism, the most prevailing since post-modernism in terms of formation of architectural spaces, apply to the interior space. Probably, after these examinations, we would make through a part of new techniques of spatial configurations and try new directions of the scope in interior design and architectural design. Therefore, the main points of the examinations in this paper, based on the essence of interior design and the trend of contemporary architectural design, underlined in the scopes of development, design elements, compositional techniques, and the case study and analysis of neo-constructivism.

住宅 各部位의 適正寸數와 單位平面의 標準化에 關한 硏究 : -住宅建設의 工業化를 爲하여-

It is considered to be a challenge confronting the people concerned to bring down construction costs and to provide housing of dependable quality within the shortest time possible. In order to meet these demands, we most establish optimum dimensions for each component of a house, standardize the unit plan, and incorporate a mass production system through the industrialization of housing construction. This study, an attempt to meet the situation, is aimed at systematizing the housing construction through the establishment of optimum standers and the standardization of unit plans. To reach the goal as set forth above, an investigation and analysis was made of the dimensions of each part and also of each room per unit plan for apartment houses, tenement houses, and private homes which were built by housing construction industries in Korea. In this regard, the theoretical value of construction planning and the optimum value through MD have been abstracted and established, and an attempt has been made to standardize the systematic unit plan of various housing types through the utilization of this system. Also, with the improved quality of housing and the proventive measures being taken against slums, this study was intended to conform with MC through the open system as far as possible, dismissing the planning standards which are bent on the current housing situation. Accordingly, taking into account the difficulty with regard to the efficiency problem involved in the unit plan, I aimed at the standardization of the unit plan partially utilizing the closed system with reservations that in the future the standardization will have to be made through the open system alone.

Today, we realize that modern buildings and post-modern buildings are rely heavily on an insistent use of elementary geometrial shapes. Some, like the square, are easy to draw and others, like the circle and the triangle, or solids based on them like the cylinder, are rather more awkward to manage. Yet the worst contemporary architects and industrial designers will use them. The idea has got about that elementary geometrical shapes are in some way better than more complicated shapes. Generally Speaking, we owe this tendency to Neo-Classical architect. But it goes back much further. The objectives of this report are to analize the process that have been developed since seventeenth century, and this tendency can not equalize with original conception of Platonism.

There has been striking tendencies in most of the developing countries that historic traditions were consciously appreared to be preserved since the early Twentieth Century. Fine Arts Museum is aimed to collect, evaluate and exhibit all the concerned materials in such a way that it could culturally contribute to the public, to the extent possible. In terms of function & spatial composition of the museum, every work of arts could properly be displayed into the space where a collective art of spatial architecture is made possible. Many architects and planners have already studied future development of planning approaches for the fine arts museum, and yet urgent need of further analysis and specific research studies is revealed in a series of problems, that could give an inevitable result for particular solution. To this respect, the study report will mainly cover the following aspects; -Understanding the nature and structure of physical composition of recently built museums abroad since last decade, -Developing programmes and planning requirement from the result of case studies for Museums prepared by the writer on the spot during planning research work in the Europe, -Defining goals and objectives of desired future patterns in museum construction and implementing these objectives in plans and proposals.

The characteristic of Formal Expressions in Deconstructive Architecture were summerized in four features through the results of the analysis. They are as follows. 1) `The relation of architectural element and intertextuality' is expressed in discontinuation of context and refusal of functional building. 2) The concept of trace expresses as connection of place, decomposing of excavation of trace, trace of axis, trace of fragments. 3) Anti-gravity expression is there to express of open cubic, to outgrow of rectangular system, to outgrow of volume, to separate of ground connection. 4) The complex compositon of abstracted geometric form is there to abstracted geometry about indefinite shape, to layer through the overlap and collage, to de-meaning and amusement of form through the pursuit of uncertainty, to indeterminate of formal meaning through operation and composion of similar form cause to the diverse of meaning.

日本現代建築의 共通的 特性에 관한 硏究

尹道根,李一珩 弘益大學校 1992 弘大論叢 Vol.24 No.2

Contemporary architecture in Japan is entering an entirely new phase in the second half of the 1980s. In the late 1960s, doubts began to be expressed about Modernism, which until then had been the recogniged mainstream of architecture. There was much discussion, but it was only in the early '80s that an active debate was initiated concerning Post-Modernism. Today, however, matters have gone beyond this, and the situation appears particulary significant the Japanese architecture world was hither to understand to be fundamentally very different from its western counterparts. It is also true that many contemporary Japanese architects have reinforced this view that japanese architecture is unknowable by using abjectives such as "mysterious" and "Far Eastern" to describe their works, albeit in part in a metaphorical sense. This was probably due to a communication gap. There are several trends in current Japanese architecture which have still come out of the Japanese tradition of life, culture, region, climate itself. At the same time, stance of comtemporary Japanese architecture start from a common basis in world's design stream which can be called Post-Modernism, Deconsrtuctivism, Neo or New-Modernism. This study is aimed at analysis of common characteristics in comtemporary Japanese architecture.
