Optical Switch Network의 Implementation에 관한 연구
김영택,김현천 慶星大學校 1991 論文集 Vol.12 No.3
To implement a kind of Broadband Integrated Digital Service, Photonic switching network system with a chracteristic of rearrangeably Non-blocking ability has been studied. Two implementation module 222, were used in performance analysis to compare the traffic capacity concerning the rearrangement probablity Results show that the difference between the two non-blocking modules is trivial in an implementation point of view.

In order to find out the effect of Anti-Histamine of the Sungmagalkuntang and Sungmagalkuntang-plus-samultang I've investigated the effect of the time to death, the peripheral vascular Peaneability, the amount of secretion of Gastric Juice, the total Acidity of Gastric Juice, the contraction of Intestine Tube by Histarnine and the effect of the Skin-Reaction by the decrease of DNCB. These results are following 1. The effect of Mice s rime to death by Histamine was that the injection group of sungmagalkuiigtang and the injection group of sungmagalkungtang-plus-samultang both have had the effect of the extention uf the time lo death, which indicated a statistical significance in comparison with comparative group. 2. The effect of the increased vascular permeability by Histamine was that the injection group of sungmagalkuntang and the injection group of sungmagalkuntang-plus-samultang both have had the effect of the restraint of the increased vascular permeability, which indicated a statistical significance in comparison with comparative group. 3. The effect of the the amount of the secretion of Gastric Juice by Histamine stimulus was tirat the injection group of sungmagalkuntang-plus-samultang only has had the effect of restraint of the increased of the secretion of Gastric Juice, which indicated a statistical significance in comparison with comparative group. 4. The effect of the chan,ge of total Acidity of Gastric Juice by Histamine's stimulus was that the injection group of sungmagalkuntang-plus-samultang only has had the effect of the restraint of the increase of tolal Acidity of Gastric Juice,, which indicated a statistical significance in comparison with comparative group. 5. The effect of the contraction of Intestine Tube by Histamine was that sungmagalkuntang and sungmagalkuntang-plus-samultang both have had the effect of the contraction and the restraint According to the increase of the density, the effect of the restraint was more clear. But the difference of the effects between two substances had little. 6. The effect of the reaction of skin by the decrease of DNCB was that the injection group of sungmagalkuntang and the injection group of sungmagalkuntang-plus-samultang have had the decreased effect of the Skin-Reaction in comparison with comparative group. sungmagalkun-tang-plus-samultang aws more effective. In these results shown above, both sungmagalkuntang and sungmagalkuntang-plus-samultang was shown as more effective one

Adult intussusception is a rare condition, unlike in children. There is an identifiable bowel lesion as a leading point in most of cases. Retrospectively we reviewed 22 patients with adult intussusception, and analyzed CT scans of 13 patients during the last 5 years. Twenty of the 22 patients had various causes of intussusception and 7 patients were as sociated with primary malignancy, 5 patients with benign tumor, and 4 patients with adhesive band. CT scans of 13 cases all showed characteristic target appearance or sausage-like soft tissue mass within the bowel, suggesting intussusception. In eleven of the 13 patients(84.6%) an intussuscepting mass was identified on CT scan as the lead point. Specific diagnosis for the cause of intussusception could be made by CT in four of 13 cases (three lipomas and one mucocle). In conclusion. CT is useful not only for the diagnosis but also for the evaluation of the leading causes of intussusception. Especially, CT could determined the exact causes of intussusception in cases of lipoma and mucocele.
