The author made a clinical study of postoperative respiratory function and analgesic effect of intrathecal morphine HCI which had been administered to 40 of a total 80 adult male and female patients who underwent abdominal operation with spinal anesthesia from March, 1980 to September, 1981 at Dept. of Anesthesiology, Busan National University Hospital. The results obtained were as follows; 1) Vital capacity during 6 to 12 hours after operation was significantly increased in patients given intrathecal morphine as compared with other groups of patients. 2) Patients given intrathecal morphine showed a significant increase in tidal volume during 6 hours after operation. 3) There was no significant change in the level of arterial oxygen tension at pre-and postoperative period in all groups of patients. 4) The average duration of postoperative analgesia was 33.6 and 33.8 hours respectively in patients who were given intrathecal morphine.

The purpose of this thesis is to get data which need to set up the positive directions for Coeducational Technical High School. To attain these data, Technical High School boy and girl students' consciousness of career was examined, and then their consciousness levels of career, choices of career, views for getting a job, and states of career education were compared and analyzed. The main points to accomplish the purpose of this thesis are as follows : 1. Do Technical High School students' motives of entrance and major choice indicate a meaningful difference by both sexes? 2. Do Technical High School students' self-consciousnesses indicate a meaningful difference by both sexes? 3. Do Technical High School students' consciousnesses of career indicate a meaningful difference by both sexes?

Due to the environmental change in market, cost, delivery time and quality are critical in manufacturing industry. One challenging alternative is employing ERP system. In this paper, the procedure developing ERP for small and medium industry will be presented. Several effects such as real time production scheduling and work load analysis, information sharing over all department and improving flexibility in receiving orders will be expected.
생산공정 혁신 방안에 관한 연구: Physical Programming을 이용하여
차명수 경성대학교 산업개발연구소 2010 산업혁신연구 Vol.26 No.1
본 논문은 Physical programming을 사용하여 열화(deteriorating)하는 공정에서 초기 공정 평균과 생산주기를 결정하는 두 가지 모델을 다루고 있다. 내용물의 양이 규격하한을 만족하지 못하는 경우 이를 불량으로 간주하는 문제를 canning 문제라 한다. canning 문제는 많은 사람들에 의해 연구되어 왔으나 품질과 비용을 동시에 고려하는 모델은 거의 연구된 바가 없다. 대부분의 연구들은 품질을 비용으로 변환시켜 단목적 함수의 문제로 다루었다. 그러나, 현실적으로 품질을 비용으로 정확히 변환시키는 것이 매우 어렵거나, 불가능한 경우가 일반적이다. 본 연구에서는 품질과 비용을 두 개의 목적함수로 하고 Physical programming을 사용하였다. Physical programming은 다목적 최적화를 다루는 비교적 최신의 기법으로 다목적 최적화에 있어서 목적함수의 선호도를 가중치로 변환시키는 유용한 도구이다. 본 연구에서 사용하는 design metric은 불량률과 생산비로 두 개 모두 값이 적을수록 좋은 척도이다. 결정변수는 초기 공정평균과 생산주기이다. 품질특성은 정규분포를 따르며, 열화가 시작되는 시점은 지수분포를 따른다고 가정한다. 열화에 의해 공정평균이 일정하게 변화하는 경우와 공정평균이 시간에 대해 선형적으로 변화하는 경우의 두 가지에 대한 모델을 제시하였다. 각 모델에 대한 수치 예제도 다룬다.

In this paper, the optimal replacement policy for a car under warranty is considered. It is assume that Customers buy a new or used car. We propose an optimum cost model for car replacement which minimize the total average cost. Numerical example will be given and the meaning of it will be discussed.

Technical High School students want to get a job to stand on their own feet and to become a member of a community. Therefore, we will have to reinforce the education so that Technical High School students can prepare for society that centers their faculty and be applied to actual spot of industry. Vocational School students receive the consignment education but want to go on to university. Therefore, by diversifying the kinds of job in Vocational School. providing the students with the wider guidance for getting a job and the information for getting a job, and developing the new program, we will have to provide the students with a practical vocational education.
