Primary lymphedema tarda is considered to be a congenital disease with delayed manifestations. The cause is unknown; an autoimmune destruction of lymphatic channels can be hypothesized. We report a case of isolated lymphedema of the left lower extremity in a 38-year-old male. The diagnosis of lymphedema was confirmed by lymphoscintigraphy and appropriate diagnostic studies were done to rule out other known causes of limb edema. We report a rare case of primary lymphedema tarda of the left lower extremity.

Background and Objectives : Helicobacter pylori (H. pylori) is accepted as a principal cause of chronic gastritis and an important factor in the pathogenesis of peptic ulcer and gastric malignancy. The aim of our studies is to investigate relationships between H. pylori and gastric epithelial cells. Materials ðods : One hundred and eighty one H. pylori positive cases of gastric biopsy specimens were studied immunohistochemically and ultrastructurally. Results : p53 positive staining exhibited foveolar epithelial hyperplasia in 1 out of 32 cases, regeneration in 2 out of 12 cases, incomplete intestinal metaplasia in 5 out of 41 cases, complete intestinal metaplasia in 3 out of 18 cases, chronic ulcer in 1 out of 9 cases, tubular adenoma in 2 out of 14 cases and intestinal type of adenocarcinoma in 16 out of 21 cases. Ultrastructurally, H. pylori was observed to be in direct contact with the microvilli of the target cells and was demolishing the surface microvilli. The organisms were in close contact with the uncoated cell membrance. Penetration into the gastric cells by a few organisms was associated with marked cell damage and ultimately to cell disintegration. Conclusion : Our results suggest that H. pylori plays a role in the pathogenesis of gastric cancer, leading a relatively slow, long lasting process that induces chronic active gastritis, intestinal metaplasia, dysplasia, and adenocarcinoma of intestinal type.

A strengthening technique for reinforced concrete beams using external unbonded reinforcement offers advantages in speed and simplicity of installation over other, established, strengthening techniques. The purpose of this paper is to investigate the capabilities of a new retrofitting technique, namely external prestressing(Bow), for flexural strengthening of beams. The paper provides a general description of structural behavior of beams strengthened using the technique. Results of 2 physical tests on strengthened reinforced concrete continuous beams are reported and compared. It is shown that the technique can provide greater strength enhancement to lightly reinforced sections and that provision of deflectors enhances efficiency.

This survey introduces such highly influential factors based on the related literature review here in korean and aborad and examines their interrelation, and it is also examined developing stage of information system organization, if there is any difference in the importance of major factors that affects accounting information system performance in every growth phase, when the turning points, internal environment changes of company on the way from computer resource mangement tp data resource management is divided as marked ones, each low and high phases. The hypothesis based on the conceptual framwork can be largely divided in to two kinds ; the first hypothesis is on the relationships between the results of the accounting information system performance and major affecting factors and the second one is on relationships betwwen the development stage of information system dpt., and maf. The outcomes of empirical analysis of these hypothesis can be concluded like this : First, the correlation with the performance variables and four major affecting variables except the authority of information system dpt. has been proved to be significantly positive. Secondly, top management commitment is found to be related with two performance variables in every development stage. The relationships with user involvement indicate singnificant relevancy with performance variables in every development stage, but the relationship between use of system and user involvement has been more significantly presented in the low stage. From these result of analysis top management commitment is the most important factors in affecting the performance of accounting information system and interdependencu between the user dpt. and information system dpt., user involvement follows however., the authority of information system dpt. has no leverage.

This study aims to analyze illustrations in Wise Life textbooks for the 6th and the 7th elementary school curricula. The 7th textbook has been decreased in the number of illustrations comparing with the 6th one. But illustrations per each page in the textbook and each lesson have been increased in number. In the ratios to a page face, these illustrations for the 6th and 7the textbooks are mostly below 1/4 up to now. Meanwhile, the illustrations of two, 2/3 and 1/3 ratios to a page face have been increased in the 7th textbook, relatively. So, it is considered that the stupid arrangements of these illustrations for 6th textbook have been improved for 7th one. Photos of above illustrations are mostly quadrangular and circular in the 6the and the 7th textbooks. Of above photos, the quadrangular ones in the 7th textbook have been decreased about 10% comparing with ones of the 6th textbook. Although the role of motivation inducement for the illustrations of the 7th textbook is more or less improved, those ones keep below 10% so far. The illustrations of the present textbooks possess backgrounds showing urban and farming lives, in general. On the other hand, it is suggested that the contents of several life styles which are exampled as a fishery village or developing field of oceanic resource would be included in the illustrations of Wise Life textbook, in future.

Background and Objectives: Immunolabelling of interstitial Cajal(IC) cells in the intestinal wall has recently been developed by using a specific marker, the anti-c-Kit antibody. Substance-P is a well-known neurotransmitter in the gastro-intestinal tract. Since the gastro-intestinal wall structures have already been well documented in the guinea pig, immunohistochemistry was done for the c-Kit-positive IC network and substance-P receptor(NK1R) in an attempt to provide a morphological basis for the mechanism regulating gastro-intestinal movement. Materials and Methods: Cryosection and whole-mount preparations of guinea pig small intestine and colon were single and double immunolabelled using the anti-c-Kit and NK1R antibodies. Immunolabelled specimens were observed under a confocal laser scanning microscope. Results : According to a three dimensional reconstruction study, it was found that (1) the c-Kit-positive celluar networks were widely distributed in the intestinal wall, (2) c-Kit-positive celluar networks encircled the ganlion, with strands in reticular configurations, and (3) the c-Kit-positive cells showed colocalization with NK1R in circular muscle(CM), not myenteric plexus(MY). Conclusion: The charateristic profiles of IC containing c-Kit-positive celluar networks and the relationship between c-Kit-positive and NK1R-positive structures provide a morphological basis upon the mechanism regulating gastro-intestinal motility.

The purpose of this paper is to evaluate the response of Precast Prestressed Concrete Interior Wide Beam-Column Joint subjected to cyclic lateral loading. To this end, the experimental investigation was performed with six half-scale specimens of interior connection. The design parameters are the beam to column depth ratio, and the number of tendons within column core. One of the specimens, IJH-6, is modeled for the connection at the top floor of a structure. The test results showed that the specimens sufficiently resist up to limiting drift ratio of 0.035 in accordance with the provisional standard by ACI of acceptance criteria for concrete special moment frames.

Experimental results from the cycle lateral load tests for post-tensioned precast wide beam-column connections were presented. Six exterior beam-column assemblages of half scale were tested in the laboratory. The specimens consist of U-shaped precast wide beams and concrete columns. The continuity at the beam-column joint is achieved with the topping concrete and post-tensioning. The specimens were designed with parameters of the beam-to-column depth ration and the number of tendons within column core. The test results showed that the post-tensioned precast wide beam-column connection satisfied the provisional standard by ACI of acceptance criteria for concrete special moment frames.
