So the essential point of warehouse's function is exchanged to attach greate important to information technology and client services. But the existing warehouse management systems have many weak points in part of information technology and client services. In this paper, we suggest the plan of introducing the RFID system into warehouse management system for an efficient management. We also develop warehouse management system to show in realtime 3D a location information of goods in the warehouse.

사설시조에 나타난 시·공간 표상의 양상

이형대 한국시가학회 2002 韓國 詩歌硏究 Vol.12 No.-

Space is related with the condition of life. Time is related with the process of life. which is the form of revealing life. In this respect, space and time are closely related with each other. This paper aims at elucidating aspects of spatiotemporal representations reflected in the dimension of experience and imagination, particularly in the difference of dwelling environments which form primitive experiences in poetics. The spatiotemporal representions in Saseolsijo(a form of Sijo(Korean ode) with unlimited length in the middle verse) incorporating experiential lyricism in rural life are not only circular and sequential, but also showing limit of closed life-world. That may be primarily because space and time are represented in close connection with the lives of people who had lived in such environments. On the contrary, spatiotemporal experiences in city life are intermittent, segmental and floating. These characteristics may be mostly caused by the facts that in the city goods are produced and consumed without any connection with the natural law of seasons and people maintain life pattern on the basis of the law of competition. Separation between working place and home and that between working time and leisure time are the marked indications. So, I argue that the sentimental aspects in city life were reflected or, reversely injected in the often occurred scenes like 'spots of amusement' and 'lapses of the moment' in Saseolsijos. In an extreme of spatiotemporal consciousness are expressed hallucinatory spatiotemporal representations. In them, the sequentiality of space and time disappears and a new semantic term gets formed. This formation depends on the writer's will and it can be variedly transformed by her. So, I conclude that it is similar to productions of romantic imagination.

In order to observe the effects of freeze-dried saliva of Agkistrodon caliginosus and Agkistrodon saxatilis, the Korean poisonous snakes, on the contractility and action potential of frog ventricular muscle cells, the isometric tension in a vertical chamber and the action potential in horizontal chamber were recorded and analyzed. The following results were obtained; 1. ED_50, to reduce the contractility was 4-8ug/ml in the case of A. saxatilis and 8-16ug/ml in the case of A. caliginosus which all were higher than that of A. brevicaudus and the inhibitory effect on the contractility was greater in the case of A. saxatilis than that of A. caliginosus. 2. In the case of A. saxatilis, APD_50(time to repolarize 50% of action potential amplitude) decreased from 820±80 ms to 710±60 ms, the overshoot and the V max(Maximum depolarization rate) decreased from 34±8 mV to 18±4 mV, from 98±8 V/s to 89±4 V/s respectively. 3. In the case of A. caliginosus, ADP_50 decreased from 880±70 ms to 720±40 ms, the overshoot and the V max decreased from 28±6 mV to 20±4 mV, from 89±8V/s to 77±12V/s, respectively. 4. Inhibition of contractility and overshoot potential were more prominent in A. saxatilis and APD_50 was more decreased in A. caliginosus. The above result showed that Korean snake venoms would decrease the ionic current underlying the rapid upstroke phase and slow inward currents by calcium ions simultaneously in a frog ventricular muscle cells.

목적 : H. pylori가 위장관 질환의 병인에 깊은 관련이 있어 이의 적절한 진단 및 치료가 중요하게 대두되고 있다. 이에 저자들은 소화기 증상을 주소로 내원한 환자들을 대상으로 내시경 검사를 실시하여 H. pylori검출을 위한 CLO검사, IgG 항체검사 및 H&E 염색 등을 시행하여 각 질환별로 H. pylori 감염의 양성율을 알아보고 검사법에 따른 민감도 및 특이도를 그 유용성에 대하여 조사하였다. 대상 및 방법 : 1996 4월에서 8월까지 경북대학교병원에 소화기증상을 주소로 내원한 총 313명의 환자를 대상으로 내시경 검사를 실시하여 H. pylori 검출을 위한 CLO 검사, IgG 항체검사, 조직염색 검사를 실시하였다. 결과 : 전체 대상 환자수는 313명이었고 연령별 분포는 16세부터 80세 까지 다양하였으며 그중40대, 50대, 60대가 각각 69예(22%), 73예(23.3%), 65예(20.8%)로 전체 환자중 66%를 차지하였다. 남녀비는 2.07 대 1로 남자가 많았다. 대상환자의 평균나이는 52±15세였고, 전체 대상환자에서 H. pylori 양성군과 음성군의 평균나이는 각각 50±15세, 54±15세 였고, 궤양환자군에서 H. pylori 양성군과 음성군사이의 평균나이는 각각 49±14.8세, 55±13.8세로 나타났다. 각 질환별분포는 위염이 72명(23%), 십이지장 궤양이 85명(27.2%), 위궤양이 80명(25.6%), 위암이 20명(6.4%), 비궤양성 소화불량이 13명(4.2%), 기타가 43명(13.7%)이었으며, H. pylori 감염 양성율은 위염이 71%, 십이지장 궤양이 86.8%, 위궤양이 58.3%, 위암이 75%, 비궤양성 소화불량이 75%였으며 특히 유문륜 궤양에서는 100%의 양성율을 보였다. 소화성 궤양군과 비궤양군에서의 H. pylori 양성율을 비교해 본 결과 궤양군에서는 73.1%, 비궤양군에서는 72%로 통계학적으로 차이는 없었다(P=0.91). 소화성 궤양환자에서 출혈이 동반된 군과 동반되지 않은 군에서의 H. pylori 양성율을 비교해 본 결과 출혈이 동반된 군에서의 양성율은 54.5%였고, 출혈이 동반되지 않은 군에서는 77.5%의 양성율을 보여 출혈이동반되지 않은 군에서 통계학적으로 유의하게 높았다(P=0.014). 나이에 따른 양성율을 알아본 결과 50세 이하에서는 78.5%였고, 50세 이상에서는 67.5%로서 양성율이 낮았으나 통계학적으로 유의성은 없었다(P=0.052). 각 검사법에 따른 민감도 및 특이도는 전체 환자중에서는 CLO검사가 88.9%, 96.1%, IgG항체검사 90.8%, 58.5%, H&E 염색검사 86.9%, 79.2%로서 민감도는 비슷하게 나왔으나 CLO검사는 상대적으로 특이도가 다른 검사법에 비해 높았다. 궤양군에서의 CLO검사의 민감도와 특이도는 92.0%, 95.6%였고, 비궤양군에서의 민감도와 특이도는 84.3%, 96.8%로서 비궤양군에서는 CLO검사의 민감도는 약간 낮았다. 나이에 따른 CLO 검사의 민감도 및 특이도는 50세 이하에서는 91.5%, 93.1% 였고, 50세 이상에서는 86.3%, 97.9%로서 50세 이상에서는 상대적으로 CLO검사의 민감도가 낮았다. 결론 : 본 연구에서는 위장질환에 따른 H. pylori 양성율을 알아보았는데, 다른 보고에서 처럼 높게 나왔으며, 진단 방법으로 사용한 CLO검사, IgG항체 검사, 조직염색검사 등은 모두 비교적 높은 예민도를 나타냈고, 그중 CLO검사가 간편하고 경제적이라는 면에서 임상적으로 유용한 검사로 여겨지나 상대적으로 CLO검사의 민감도가 낮은 비궤양성 질환과 50세 이상의 환자군에서는 CLO검사 외에 다른 검사방법을 병행함으로써 H. pylori의 진단율을 높일 수 있을 것으로 사료된다. Background: Gastric colonization by Helicobacter. pylori is common among patients with peptic ulcer and gastritis. And various diagnostic tests are available in confirming H. pylori infection. The aim of this paper is to estimate the prevalence of H. pylori infection in Gastroduodenal disorders and compare the sensitivity and specificity of the most widely available tests. Methods: A total of 313 patients were tested for H. pylori infection by IgG Ab, CLO test and H&E stains. Results: The prevalence of H. pylori infection was significantly higher in duodenal ulcer(86.8%) than in gastric cancer(75%), gastritis(71%) and gastric ulcer(58.3%)(P=0.009). The sensitivity and specificity of each test was as follows: CLO test(88.9%, 96.1%), IgG Ab test(90.8%, 58.5%), H&E stain(86.9%, 79.2%). Sensitivity of CLO test in peptic group was 92.0%, whereas in non-peptic group, it was 86.3%. Sensitivity of CLO test in age under 50 was 91.5%, that over 50 it was 86.3%. Conculsions: There is a strong association between H. pylori and gastrointestinal disorders. CLO tests have relatively high sensitivity and specificity, especially in peptic group and younger age(below 50 yr)group. But in those patients in which CLO tests are less sensitive (age>50 or non-peptic group), more than one test may be necessary to diagnose the presence of the organism.

This study was carried out to evaluate the feasibility of current lead indicators used in screening lead who were sspeted to have been exposed to lead were selected as 'case'and 207 female workers from non-lead industry were selected for 'control'. The results obtained were as follows: 1. The mean values of blood lead for case and control were 31.4㎍/dl, 22.2㎍/dl,respectively. The difference observed in the mean concentration between case and control was statistically signifi-ant(P<0.01) 2. The mean values for blood ZPP by hematofluorometer for case and control were 31.3㎍/dl, 25.4㎍/dl,respectiely. And difference between two groups was statistically significant(P<0.01). 3. No statistically significant correlation was found between working duation and blood lead, blood ZPPlovel. 4. According to the simple correlation analysis,ZPPand urine lead were found to be statistically correlated with blood lead(P<0.01) 5. According to the discriminant analysis using blood lead as a dependent variable, it showed 89.1% predictability when using 40㎍/dl as a cutting value which is used as a screenig cutting value for industry workers health examination, while 81.8% for 30㎍/dl,77.54% for 20㎍/dl, respectively. 6. Lead related simptons which is used for screening the lead ntoxicated patients were used as a dependent variables in multiple regression analysis to find useful lead indicator. And significant independent variables were found to be ZPP, Age, and Hct. 7. Above results suggest that objective evalution of feasibbility of several lead indicators should be developed to correct the disutility of current lead screeng system in Korea.

The present study deals with student circle activities at Pusan National University in an effort to improve student circle guidance. University circles are regarded as influencing an individual's self-growth. Two sources of data were used for this research. A total of 764 students at Pusan National University who were randomly sampled out of the registered students in 1982 Spring semester were the main subjects. Another source for the study were from 70 student circle leaders whose responses to another questionaire in a special leader training session held on October of 1982. Student respondents for this study were analyzed in three groups;(1) students who participate in circle activities at the time of the research, (2) students who participated in a circle in the past but not active at the time of the questionaire interview, (2) students who have never been members of a circle. The student respondents who were or have been members of the circles in which they participate:social service circles;academic circles; circles for special hobbies; religious circles; athletic circles for special hobbies; anti-communism circles. Some of the important findings from this research are summarized in the following. (1) Pusan National University students enjoy more student circle activities as demonstrated in the sheer number of student circle activities registered in the Student Affairs Section of the University. Circles with friendship purpose seem to decline, while circles for special hobbies and academic purposes tend to increase. (2) Many students were found to drop out of the circle activity mainly due to the lack of the circle activity information before their participation in those circle. More coeds than male students show this tendency. (3) Student circle members with specific purpose and goal in mind before participating in those circle regard aircle activity as contributing to the self-growth. (4) Many respondents think that circle activities are vital and necessary in the campus life. However, they do not find proper circle to paticipate. (5) The role of the student circle guidance professors was found to be important. (6) Problems for funding the student circles and finding meeting places for the circle activity remain to be solved. In short, the present study underlines the importance of the activization student activities which can be achieved through intensive circle guidance by circle advice professor and proper funding.
