Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

Leiomyomas are common in the myometrial layer of the uterus, though they are rarely found in other reproductive organs. Leiomyomas are benign, hormone-sensitive smooth muscle tumors. They develop during the reproductive years and regress after menopause. Preoperative diagnosis is difficult to make. We present a case of a 54-year-old woman with a vaginal wall tumor. The management in this case included surgical excision Histologic examination definitively confirmed the diagnosis of a vaginal leiomyoma. We report the details of this case along with a brief review of the literature.

교량의 실시간 거동 모니터링을 위한 GPS의 적용

박운용,정성모,곽두호,이흥규 東亞大學校 大學院 1999 大學院論文集 Vol.24 No.-

Real Time Kinematic GPS will allow a multitude of monitoring, navigation and engineering applications. Applications inclued real time deformation and movement monitoring and real time automated plant control. In a low dynamic environment, with a short baseline length, it is possible to position a roving receiver to an approximate accuracy of less than 5mm within a few seconds of thestart of the ambiguity. One Engineering application is the monitoring of the movement of cable suspension bridges. Such structures are capable of movements of up to a few meters under adverse wind conditions or heavy traffic loads. The use of relative OTF positioing at strategic points upon the bridge would allow close monitoring of the bridge's movements and calculate deformation and long-term deterioration factors for the bridge. Future bridge designs and traffic management schemes could also benefit from the monitoring system.

Photoacoustic Effects on Material-coated window

朴奉斗,尹志洪,韓聖愚 慶北大學校 産業開發硏究所 1979 硏究報告 Vol.7 No.-

Photoacoustic effect was studied with the air cell and tungsten lamp. The air cell had a material-coated window. As the coating material, one of the following materials was used; the lamp black, copper, nickel and aluminum. The incident light was chopped by the rotating disc, and entered through the material-coated window. The produced photoacoustic signal intensity is approximately inversely proportional to the chopping frequency. This effect was the same as that when the chopped light entered into the air cell from the opposite side, gas side. The signal intensity, however, was much smaller than that of tho light incident from the oppsite side. The photoacoustic signal intensity was varied with the thickness and kinds of coated material. In the case of aluminum the intensity was rapidly decreased when thickness increased. In the case of copper, however, the intensity was increased until the thickness increased to a certain value, and over this value the intensity was decreased slowly.

The purpose of this research is to understand the sex culture of college students by surveying the students' awareness and experience about sexual harassment and sexual assault, and their responses and opinions, and ultimately to provide basic data for in-campus programs and guidance against sexual harassment and assaults. To this end, the survey was composed of three parts; awareness on sexual harassment and sexual assaults, experience of sexual harassment or assault, and opinions on the consultation program on harassment and sexual assaults. The survey was conducted among 1,000 students in 9 colleges of Cheju National University (CNU), and analyzed the answers of 964 respondents. This research used SPSS statistical program to process data and conducted t-verification and F-verification. The results of the research are as follows. 1) The awareness on sexual harassment and assaults CNU students' common notions on sexual assaults, attitudes toward sexual relations, views on sexual harassment are a little different from the generally accepted ones, but lower than socially expected. In general, male students have more stereotypes on these matter sand take them less seriously than female students. Both of them have a man-oriented attitude. While female students take sexual harassment and sexual assaults as social problems, male students just take them as flirting. 2) Experience of sexual harassment and assaults After conducting a survey with three cases; committing experience, suffering experience, and experience of hearing of or seeing, there is no case in committing experience. In case of suffering sexual harassment or assaults, verbal, nonverbal, and physical cases are answered in order. In case of verbal harassment, female and male students suffer similarly, while more male students experience nonverbal, physical harassment and assaults, which shows that sexual harassment and assaults are happening irrespective sex. As to inflictors, strangers are the most. Sexual harassment and assaults occur more in other places rather than in campus, while in-campus cases are relatively less answered. In-campus cases are mostly between students, but there are cases where a staff member or a professor is an assailant, though very rare. About the reaction to sexual harassment and assaults, the highest number of students, male and female, answered they say "No" and ask to stop. Their reactions seem to be active and desirable. Most of them talk with their friends about the problem. 3) Opinion on the sexual harassment and assaults consultation center The level of awareness of CNU students about the center's regulations on sexual harassment and assaults cases is very low; therefore they said the center should give the priority to education for sexual assaults prevention. - As equally important as to resolve the cases of sexual harassment and assaults, there should be efforts to build a common perception on sexual harassment and assaults. To this end, education and discussion programs should be activated and continued to give students a right understanding of this issue. - In-campus sexual harassment and assaults are mostly between students, but there are cases where a staff member or a professor is an assailant, though very rare. Since such a case, if happening, is related to officials' duty and authority, it should be completely prevented. - Education program for the prevention of sexual harassment and assaults would be desirable to conduct in a small group consisting of friends or peers. - It is needed to widely inform members of the university about the regulations on sexual harassment and assaults. In this regard, compulsory and regular education should be offered to all the CNU students rather than one time campaign. - It would be desirable for the center to conduct all-year programs for the prevention of sexual harassment and assaults.
