Experimental study using 36 rats was operformed to survey whether vein interposition was able to serve as a conduit for nerve regeneration and to compare this result with those of the nerve graft. Gross and histologic examination revealed orderly growth of nerve fibers through tlhe vein graft in case of 5mm nerve gap up to 1 month, and in case of 10mm gap up to 2 month, and nearly 15mm gap up to 3 months following experiment. The regenerating axon grew up along the internal surface of the vein graft and any distinct intraneural as well as extraneural fibrosis was not observed. In conclusion, nerve repair using vein graft could be employed in the clinical field if the result of the functional study including E.M.G. shows effectiveness.

A Program always has been the element of architecture, which has advented since 18C. And it has been changed simultaneously with the alteration of architecture. In modern architecture, the functionalism handles with a program as rational and functional side of architecture. When a social change progresses and gets complex, a program of architecture also gets complex. A new interpretation about program appeared in response to the functionalism, in which the form and the configuration of a building was decided with its use. One building denoted singular program, but now it includes diverse programs. The program itself shows not only with the function of a building but also with social sense. As a result, the form and the configuration of a space is closely related to a program. This paper considers alterations of program accompanied by social changes and finds out the relationship between new programs and space configurations. And also, we are trying to use space syntax which is a quantitative method to analyze physical space configurations. New York PRADA, designed by Rem Koolhaas, coexists with two programs such as commerce and culture, and shows the relationship between a contemporary society and a new program. Searching for the relationship of space configuration and program, we find out the alteration of space configuration in the contemporary society. In the future, this could develop a comparative study of space configuration in modernism buildings which are used with the same purpose. Also space analysis based on the scientific theory will be a foundation in understanding various complex spaces.

The purpose of this study is to develop application method of structural welded wire fabric(WWF) for practical use in domestic construction industry. One of the main problems of adapting WWF for building construction is the various types of fabric, so the productivity in the factory and in construction field is decreased. The result of this study are as follows. The shape of welded wire fabric was proposed for application in slab and wall(especially the shape of WWF for slab should be one direction reinforcement type). And economical advantage of WWF was analyzed. WWF could be adapted 80.4% cost of SD400.

In domestic construction industry, re-bar work is one of the conventional works that have low productivity and are done by outdated method that is mainly independent on just manpower. And in urban area construction project, the basement covers all of the site, so there is no enough space for stocking and manufacturing re-bar. Nowadays re-bar factory manufacturing is widely spread for coping with this actual problem and developing the outdated re-bar work. But there is little development of re-bar factory manufacturing from its beginning and the dissonance is growing in the job-site using re-bar factory manufacturing. So in this study, we analysed the status of re-bar factory manufacturing and suggested the application method of re-bar factory manufacturing for more practical use. The results of this study are as follows. For successful adaption of re-bar factory manufacturing (1) the partnering of the participants is very important. So in the time of making contract, the method for improving partnership must be considered. And (2) for lessening the re-bar loss in factory manufacturing, it is considered using the Coil re-bar. Finally (3) for making the work process between job-site and factory more streamlined, it is needed making the standard of bar-list shape ID.

Objectives: To compare the efficacy of two types specific exercise intervention (deep and superficial abdominal muscle exercises) in the treatment of patients with chronic low back pain (CLBP). Design: A randomized, comparative, repeated-measures. Subjects: Twenty-four patients with CLBP (at least for 3 months), mean age±SD=51.58±16.21 (yrs). Methods: Twenty-four patients with this condition were assigned randomly to two treatment groups. Both first and second group underwent 3 weeks specific exercise treatment program. The first group specific trained for the deep abdominal muscles. The second group specific trained for the superficial abdominal muscles. Results: After intervention, the first group showed a statistically significant reduction in pain intensity and functional disability levels (p<.05). The second group showed no significant change in these parameters after intervention (p>.05). Conclusions: According to results, a "deep abdominal muscle exercises" treatment approach appears more effective than a "superficial abdominal muscle exercises" treatment in patients with CLBP.

In modernism, Functionalism of architecture handled program with rational and functional side. New translation about program appeared repulse of functionalism, which form and configuration of building was decided with its use. Which building included singular program, now includes diverse program. Program itself aspects not just with function but also with social sense. As a result form and configuration of space changes. This paper considers program change accompanied with social change and find out the relation between new programs and space configuration. Give quantitative method a trial, space syntax, to analyze physical space configurations. New York PRADA, designed by Rem Koolhaas, coexists with two programs commerce and culture. Prospect the relation between contemporary society and new program and find out what kind of relation to confirm contemporary social change of space configuration. This could develop comparative study of space configuration in same used modernism buildings. Also space analysis based on scientific theory will be a foundation in new space analysis.

이윤원,이민순,윤상욱,김진수 中部大學校 自然科學硏究所 1999 自然科學硏究論文集 Vol.8 No.1

수락계곡에 있어서 산록시면 하부의 이치림의 군락구조에 대한 속성을 조사한 결과 다음과 같이 요약할 수 있다. 1. 본 군락은 54종의 식생으로 구성되었는데 교목층은 참나무류가 우점하고 있으며, 아교목층 저목층으로 내려갈수록 서어나무 신갈나무의 중요치가 높아지고, 초본층에서도 서어나무 물푸레나무 치묘가 많이 발생하고 있으므로 굴참나무가 우점하는 군락에서 신갈나무, 서어나무 군락으로 천이 cycle이 진행중인 것으로 판단된다. 2. 군락전체의 종다양도는 1.5452로 높았으나, 교목층의 종다양도는 낮았고, 종내경쟁이 심하였으며, 종간경쟁은 초본층이 가장 심하였다. 또한 저목층에서 안정도가 가장 높게 나타났으며, nich breadth는 초본층이 가장 높게 나타나는 것을 볼 때 초본층에서 교목층까지 차례로 생태적 지위가 재편성되는 과정으로 판단된다. 3. 수고 분포도와 흉고직경급 분포도를 토대로 군락동태를 예측해본 결과 천이 초기종인 굴참나무, 갈참나무가 교목층에 우점하는 군락에서, 천이 후기종인 신갈나무, 서어나무가 침입하여 천이가 진행중인 군락으로 판단된다. This research was aimed at figuring out the characteristics of community structre of secondary forest ecotone of deciduous broad leaved trees in foot slope of Wolsobong area, Which valley and foot slope and hill side doing net crossed. It can be expected to provide the fundamental data for tending and natural regeneration of broad leaved forest, in the Mt. Daedun as being known as temperature middle zone. The results are such as follows: The vegetation of the secondary forest ecotone, which foot slpoe and hill side being crossed, was composed of 54 species, the canopy domineted species, Quercus spp., for example. And under story, shurb layer was going lower, dominance species were Carpinus laxiflora, Quercus monglica. So it might be said that the investigated area is doing succession at the present time. Species diversity appeared 1.5452 at high values. Therefore the investigated area is reflecting species composition by environmental factors. On the other hand, at the each layer level, species diversity of the upper layer was lower values and interspecific encounter of herb layer the highest. And it may be concluded that niche breadth does appeared reforming, due to the stability of shurb layer strong of intraspecific encounter. Through analyzing dynamics of the community with using data, height distribution and D.B.H. class distribution range, Quercus variabilis, Quercus aliena species were rapidly growing well adapting. Afterwards it is assessed that the community structure of researched area will be obviously devoloped climax such as dominated Quercus monglica or Carpinus laxiflora community.
