The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was investigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 ㎎/㎏ b.wt. in CCl_4-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 ㎎/㎏ b.wt. in CCl_4-induced chronic liver disease, 30 ㎎/㎏ b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

Objective : Our purpose of this study was to determine the clarity and consuming time of fetal surface screening in thirty-eight fetuses from 24 to 32 weeks of gestation by use of two and three-dimensional ultrasonography. Methods : From May 1998 to July 1998, we performed the fetal surface screening of the fetal face, extremities, and spine. Thirty-eight fetuses of 24-32 weeks of gestation (thirty-seven normal fetuses and one abnormal fetus) were studied by use two-dimensional (AI 5200S, 3.5-5.0MHz; Acoustic Imaging Technologic Cooperation, U.S.A.) and three-dimensional ultrasonography (Volusion 530D, 3.5-5.0 MHz ; Kretz-Medicine, Korea). On the fetal face, we evaluated both orbits, nose, lips and brow. Both hands and feet, five digits and toes should be seen in this study. We evaluated cervical spine and lumbosacral junction of the spine. Results : The maternal average age of 38 patients was 29.9 years and the average gestational age was 29.7 weeks. The results of fetal surface screening were as follows : face (both orbits 89.5%, lips 92.1%, nose 92.1%, and brow 89.5%), extremities (both hands 68.4% and feet 73.7%), and spine (cervical spine 94.7% and lumbosacral junction 97.4%) by use of two-dimensional ultrasonography. By use of three-dimensional ultrasonography, results were as follows : face (both orbits 76.3%, lips 81.6%, nose 81.6%, and brow 78.9%), extremities (both hands 76.3% and feet 78.9%), and spine (cervical spine 71.1% and lumbosacral junction 73.7%). Consuming time for two-dimensional ultrasonography were 4.7 minutes for face, 11.6 minutes for extremities, and 5.7 minutes for spine. Using three-dimensional ultrasonography results were 12.8 minutes for face, 17.9 minutes for extremities, and 11.7 minutes for spine. Average consuming time of all fetal anatomic screening was 22.0 and 42.4 minutes by use of two and three dimensional ultrasonography. In one abnormal fetus had cleft lip and polydactyly of right foot which were detected all by three-dimensional ultrasonography, but we couldn't detect the polydactyly by two-dimensional ultrasonography. Conclusion : Three-dimensional ultrasonography was more time-consuming method, but we suggested that three-dimensional ultrasonography was superior than two-dimensional ultrasonography in fetal surface screening.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

In the construction industries of many developed countries, the fiber reinforced plastic thin walled structural shapes have been investigated theoretically and experimentally to develop the effective design methods in addition to the feasibility study of using this material as alternatives of conventional construction materials due to its many attractive mechanical properties. In this paper the determination methods of the design strength of glass fiber reinforced plastic thin walled structural shapes under concentric axial compression are presented by extending the existing equations for the buckling analysis of structural shapes composed of isotropic plate components. In the derivation of equations for the flexural, torsional, flexural-torsional, and flange and web local buckling stress the material was assumed to be an orthotropic and the orthotropic material properties were taken into account. In addition, the effect of Poisson's ratio on the buckling strength of fiber reinforced plastic thin walled structural shapes was investigated to find whether it is negligible for the buckling analysis of the material in which the effect was usually neglected for the isotropic structural shapes. If the effect of Poisson's ratio is neglected, approximately 4.6% lower buckling loads were obtained and this leads to a conservative section design.

As a modern material, fibers are embedded in surrounding matrix materials and unidirectionally reinforced to form orthotropic fiber-reinforced plastic materials. Desirable material characteristics such as corrosion resistance, light weight, high specific strength and stiffness make this material an alternative construction materials. For effective use of such materials, the stability of various orthotropic structural shapes composed of thin plates need to be analyzed. Generally, the buckling behavior of thin plates with a cutout at the center has been limited to empirical studies and finite element analyses. A general formulation for the buckling behavior for this case is studied. Theoretical buckling analyses of plates with a hole at the center is investigated. The geometric complexity of the problem prohibits derivation of closed-form solutions from the equilibrium equations. Thus energy principles and the assumed displacement shapes are used to consider the effects of the cutout on buckling. On all edges, the boundary conditions are assumed to be simply supported with uniformly distributed stress. Experiments are based on rectangular box specimens. The results from finite element analyses and experiments are used to evaluate the validity of the theoretical results where theoretical results are concluded to be sound.

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.
