The purpose of this study is to analyze and compare accuracy and kinematic characteristics of forehand strokes upon using the left-hand and non the using left hand in tennis. Six unskilled collegiate players who complied primary tennis course participated in this study. Subjects were requested to hit 10 balls with 4 types each: first, it was two directions(down the line, cross), second, it was two velocities(slow ball, fast ball) and then it was type of using left hand. Variables such as accuracy, time, distance, angle and velocity variables were measured by USPTA method and video cameras. The results of this study are as follows: 1) accuracy of hitting balls was not different according to the type of using left hand. While there was an interaction between ball velocity and hitting direction. 2) impact positions of hitting ball were not different according to the type of using left hand. While impact positions were done near by target direction in cross direction then down the line direction. 3) shoulder rotation angle was not different according to the type of using left hand. While shoulder rotation angle was grater in down the line direction than cross direction. 4) the maximum velocity of racket head was faster in using left hand than non using left hand.

Silicone gel breast implants may induce local(fibrous capsular contracture) or systemic(rheumatoid arthritis, systemic sclerosis, etc) complications. The exact mechanism of fibrous capsular contracture has not been fully understood. In the present study, we tried to find out the effect of silicone gel on the fibroblast proliferation which has been known as a major contributing factor in fibrous capsular contracture formation. In vitro, activated macrophages are known to secrete monokines which affect fibroblast proliferation and collagen synthesis. And tumour necrosis factor-α(TNF-α) and interleukin-6(IL-6), which were released by macrophages, were reported as potent stimulator of fibroblast proliferation. The goal of this study is to investigate the role of macrophages and tumour necrosis factor-αor interleukin-6 in the interaction of fibroblasts and silicone gel. We designed four groups, two experimental and two control, using Institute for Cancer Research(ICR) mouse peritioneal macrophage and silicone gel. For the preparation of the conditioned medium of macrophages, peritoneal macrophages were prepared and cultured for 24 hours on the silicone gel-coated and naked (not coated) surface [silicone gel-macrophage conditioned medium(SCM; experimental group) and normal polystyrene-macrophage conditioned medium(NCM; control group) respectively]. To correct the effect of 10% fetal bovine serum which was included in Rapid Prototyping and Manufacturing Institute (RPMI) 1640 medium and draw the effect only by macrophages, the RPMI 1640 medium with 10% fetal bovine serum was cultured by the same method on the silicone gel-coated and naked surface (silicone gel-macrophage free conditioned medium; SFM and normal polystyrene-macrophage free conditioned medium; NFM respectively). Each conditioned medium was added onto NIH 3T3 fibroblasts culture at a final 25% concentration of total culture medium and followed by the cultivation for 24 hours. For antibody neutralizing experiments, each conditioned medium was preincubated with polyclonal rabbit anti-mouse TNF-α antibody or polyclonal rat anti-mouse IL-6 antibody for 1 hour and then, conditioned medium with antibody was added to the culture medium of NIH 3T3 fibroblasts by the same method. After 24 hours cultivation, total number of viable fibroblast(cell growth), DNA synthesis and collagen synthesis of fibroblasts with each medium were measured by sulforhodamine B(SRB) assay, 3H-thymidine and 3H-proline incorporation respectively. The results were as follows: 1. In the experiment about the effect of the conditioned medium on the fibroblast activity, the experimental group(SCM), compared with the control group(NCM), showed a significant increase of the cell growth (p<0.01), a significant decrease of DNA synthesis(p<0.001), but no significant difference in the collagen synthesis. 2. In the experiment about the effect of polyclonal rabbit anti-mouse TNF-α antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.01), but no significant difference in the collagen syn thesis. 3. In the experiment about the effect of polyclonal rat anti-mouse IL-6 antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.0001), but no significant difference in the collagen synthesis. In conclusion, culture supernatants (conditioned medium) of peritoneal macrophages, activated by silicone gel, stimulate the NIH 3T3 fibroblast proliferation. TNF-α and IL-6, products of macrophage, are involved in the stimulation of NIH 3T3 fibroblast proliferation in an in vitro condition.

Extracting a license plate is an essential stage in the automatic car identification. Because car images are usually degraded and processes for the images are a computationally intensive job, it is difficult to extract a license plate correctly from the images. In this paper, we propose an extraction method of a license plate region based on color image segmentation. To segment the color image, we use a distributed genetic algorithm and transformed Hue-Saturation-Intensity color space as a measure of distance. The method offers robustness in dealing with deformation of car images and inherent parallelism to improve processing time. A test with car images on the roads shows an extraction rate of 93.8%. This result suggests that the proposed method works well with real-world situations, and is pertinent to be put into practical use.

Dieser Dissertation ist die Auslegung des Wesen als Reflexion in Hegels "Wissenschaft der Logik. In Hegels Denken das Wesen ist erstens 'Reflexion. Die Reflexion bestimmt sich diese Reflexionsbestimmungen, d. i. die Identitat, den Unterschied, den Widerspruch. Die Reflexionsbestimmungen haben zwar die Form, sich selbst gleich und daher unbezogen auf Anderes und ohne Entgegensetzung zu sein; aber wie sich aus ihrer naheren Betrachtung ergeben wird-oder wie unmittelbar an ihnen als der Identitat, dem Unterschied, dem Widerspruch erhellt-, sind sie bestimmte gegeneinander. Daher hat as notig, daB diese drei Reflexionsbestimmungen mit dialektischen Erlegung auslegt, d. i. daB warum es in seiner Gleichheit mit sich ungleich und Widersprechend, in seinem Widerspruch mit sich identisch, und an ihm selbst diese Bewegung des Ubergehens einer dieser Bestimmungen in die andere ist.

윤영묵,장효찬,김동석,김상원,박미옥,박재복 대구효성가톨릭대학교 1998 연구논문집 Vol.57 No.2

Lymphoma arising in mucosa-associated lymphoid tissue(MALT) is extranodal marginal zone lymphoma displaying a proliferation of follicle marginal zone-type cells(centrocyte-like cells or monocytoid B-cells), often with surrounding reactive germinal centers and lympoepithelial lesions. This typically expresses pan-B-cell markers and monotypic immunoglobulin but not CD5 or CD10. Ocular MALT consists of the lacrimal gland, lcular soft tissue, orbit, conjunctiva and cornea. Lymphoma arising in thses sites is of very rare occurrence in up to 1.5% of all patients with non-Hodgkin's lymphoma. Herein we report two cases of ocular MALT lymphoma which was very rare in the dermatologic field. Case 1, 73-year-old man, developed the right upper conjunctival swelling measuring about 2.0×2.5cm for about 1 year. Histologically, the excised lesion showed follicular centers and infiltration of centrocyte-like cells of B-cell lineage in the stroma but no lymphoepithelial lesions, consistent with low-grade B-cell lymphoma. Case 2, a 66-year-old female, had a rapid course of about 1.2×1.0cm-sized, soft, wellow mass arising from lacrimal gland of the right upper eyelid for about 1 month. Hostologically, the lesion showed diffuse patterend features admixed with centrocyte-like cells and large cells such as centroblast, compatible with high-grade lymphoma. Case 2 received combined chemotherapy of m-BACOD, with a somewhat improvement.

This paper is a thesis on the validity of abbreviation registration that middleman is omitted. Especially, I considered on the validity of abbreviation registration, middleman is omitted, since enforcement of an express provision for registration of immovables, 1990. 9. 1, in this paper. The major contents of this paper can be summarized as follows. Ⅰ. Introduction (1) A background of abbreviation registration in which middleman is omitted. (2) The explanation for the point of an argument. Ⅱ. Typical mode of abbreviation registration that middleman is omitted Ⅲ. Theory and judicial precedent of the former time, September 1, 1990. Ⅳ. Theory and judicial precedent of the later time, September 1, 1990. Ⅴ. The contents of the result be inquired by question. Ⅵ. Conclusion I studied on the validity of abbreviation registration in which middleman is omitted, have concern with an express provision for registration of immovables. The writer think so that validity of abbreviation registration that middleman is omitted must be admitted also even though an express provision for registration of immovables being enforced. The detailed reason for that is stated in chapter Ⅵ.
