문제중심학습 (PBL)은 주어진 실제 환자문제를 학생 스스로 파악하여 학습과제를 설정하며, 학습한 내용을 논리적으로 적용하여 타당한 가설을 세워가는 과정을 거침으로써 학습이 이루어지는 새로운 교육 방법이다. 경북대학교 의과대학은 PBL을 도입하기 위하여 캐나다의 McMaster 의과대학을 단기 방문하여 그곳의 의학교육을 경험하고 PBL의 필요성을 절감하여, 1994년부터 2년간 시범적으로 PBL 수업을 운영한 후, 2년간 평가와 보완기간을 가졌다. 1994년부터 1996년까지 전학기에는 4학년과 3학년, 후학기에는 3학년과 2학년을 대상으로 6명을 한 조로, 45개의 소그룹을 만들고, 각 조에는 한 명의 지도교수를 배정하여 격주로 목요일 4교시에 PBL수업을 진행하였다. 설문조사 결과 4학년은 55.1%가, 3학년은 61.4%가 PBL이 필요하다고 응답하였으며 교수들은 83.9%가 필요하다고 답하였다. 이와 같은 결과에 근거하여 1999년도부터 시작하는 개편된 의학교육과정에 PBL이 정규과목으로 채택되었고, 이에 대비하여 1998년도 2학기에 의예과 2학년 학생을 대상으로 하여 PBL을 시행하여 그 결과를 평가하였다. 1999년도에는 의학과 1학년을 대상으로, 2000년도에는 의학과 2학년까지의 학생을 대상으로 PBL수업을 실시하였다. 본 연구자들의 조사에서, 학생들이 PBL에 대하여 상당히 이해하고 있으며, PBL의 학습목적을 대부분 달성한 것으로 나타나, 정규과목으로서의 PBL 시행에 전반적으로 긍정적인 평가를 한 것으로 판단되며, 조사결과에서 나타난 단점과 부족한 부분을 보완하고 개선한다면 PBL를 정착시키고 점차 확대 시행할 수 있을 것으로 생각된다. The effectiveness of Problem-based Learning (PBL) in medical education has already been acclaimed widely. Representatives of the curriculum committee at Kyungpook National University School of Medicine paid a visit to McMaster University School of Medicine in Canada in May, 1994 in order to learn mechanics and effectiveness of PBL in its medical education and they were impressed by the efficacy of PBL. Soon after that the school launched a pilot PBL tutorial for two years from 1994 through 1996 (4-semester) as a non-credit course for senior, junior and sophomore in medical school during one semester each, to introduce PBL to faculty members and students as well. After the pilot, opinion survey on PBL from both faculty and students revealed affirmative for PBL from 55.1% of seniors, 61.4% of juniors and 83.9% of faculty members. The faculty body at medical school was then encouraged by the pilot experience and decided to include the PBL as the part of medical education reform. During the fall semester in 1998, the senior at pre-medical course was given PBL experience to prepare for implementation of PBL at school of medicine. The PBL was implemented as an essential 2-credit-hour course in each semester commencing in 1999 to the freshmen class throughout the year; it was extended to the sophomore in 2000 and to the junior in 2001. Although there had been initial excitements of over expectations, confusion, and disappointments from faculty members and students, majority opinion of both parties on continuation of PBL was positive. The issues to be settled are preparation of study cases, students learning resources, and method of evaluating students performance. The PBL was started as an essential course in medical school in 1999 after 4 years of preparation and on the basis of our interim evaluations the following conclusions were made: we have reached the following consensus that students seem to follow the objectives of PBL and new PBL tutorial has well been accepted by students; and enhancing the program by correcting currently known weaknesses, the PBL tutorials could further be expanded to be a major modality of teaching in our medical school.

The spontaneous rupture of the esophagus is an uncommon disease, but without early diagnosis and treatment, the mortality rate is high. This report is on the two cases treated at the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyu-ngpook National University. The first patient, after heavy drinking, had vomiting followed by chest pain, dyspnea and subcutaneous emphysema. After diagnosis using an esophagogram, an operation was perfomed. About a 4cm rupture was found at the lower left part of the esophagus and was primarily sutured with the intercostal muscle. The patient was weaned from the ventilator after 40 hours. The second patient had symptoms the same as the first case. Six days after the app-earence of the symptoms, the patient was treated by the Thais onlay gastric patch method. The leakage happened after the surgery and he received a conservative treatment. After discharge no abnormalities, such as leakage and stricture, were found on the eso-phagogram The two patients now live a normal life.

We evaluated the correlationship between the predicted defect size at preoperative examination and the actual defect size at operation room, by examining 69 cases of ventricular septal defect operated at the deparment of Thoracic and Cardiovascular surgery, Kyungpook University Hospital from January 1988 to December 1990. We excluded cases associated with other cardiac anomalies. Of the 69 cases, 39 are male and 30 female, forming 1.3:1 sex ratio in males favor. Their age range from 6 months to 16 year, and 4.3 on the average Their body weights are from 6 to 45kg and 15 on the average. According to Soto`s classification, perimembranous type costitutes 42 cases[61%], doubly committed subarterial type 23 cases[33%], and muscular type 4 cases[6%]. The average diameter of defect size is 8.0$\pm$3.5mm measured in 2D-echocardiogram, 5.6$\pm$3.4mm in angiogram, and 7.4$\pm$4.4mm in operative field. There is statistically significant correlation between the size from 2D-echocardiogram and actual defect size[p=0.001], and no significant difference between the two. Especially in the cases without anurysmal formation, they are nearly the same. Cardiothoracic ratio, pulmonary to systemic flow ratio, pressure ratio and resistance ratio also have statistically significant correlation. Main pumonary artery to descending aorta diameter ratio is correlated with the actual defect size. There is statistically significant correlation between the size from angiogram and actual defect size with some difference.

A 25-month-old patient with complete atrioventricular septal defect and Tetralogy of Fallot underwent repair of both anomalies. The diagnosis was established preoperatively by 2D-echocardiography, cardiac catheterization and cardioangiogram, Repair was accomplished using cardiopulmonary bypass and profound hypothermia to 18C, Closing of the atrioventricular septal defect was achieved with the use of two Dacron patchs by an atrial approach alone. Infundibulectomy and outflow tract reconstruction with the transannular pericadial patch containing a monocusp were performed. Upon the postoperative evaluation by 2D-echocardiography, mitral regurgitation was absent, but a tiny dehiscence of ventricular patch and minimal tricuspid regurgitation were noticed.

경북대학교 의과대학에서는 1996년 의학과 인정 평가시 지적된 교육과정의 문제점인 강의위주 및 과다한 강의 시간, 자율학습 기회 부족등의 문제점을 보완하고 또한 의학과 교육 목표를 구현하기 위한 새로운 교육과정을 1999학년도부터 도입 운영하고 있다. 새 교육과정의 기본 이념은 환자 중심으로 생각할 수 있는 의료인을 양성하기 위하여 임상실습을 강화하며, 학생 중심으로 자율 학습을 유도하고, 문제 중심 교육을 하며, 강의는 개념정립이 용이하도록 통합 교육을 시행하는 것이다. 전체 학점 및 강의시간수는 180학점 4395시간에서 170학점 4256시간으로 줄였으며, 변화하는 사회적 요구에 부응 할 수 있는 의사를 양성하기 위하여 1, 2학년 과정에 의료와 사회, 환자-의사 관계 강좌를, 문제중심 토의학습(PBL)을 1, 2, 3학년에 각 2학점씩 신설하였다. 사회 여러 방면에서 의료인으로써 활동할 수 있게 유도하기 위하여 4학년 과정에서 실시하던 자율선택 임상현장 실습을 4주로 늘리고 2학점을 배정하였다. 새 교육과정을 원활하게 시행하기 위하여 3개 교실을 신설하였으며, 교육환경을 대폭 개선하고 확충하였다. 그러나 유급생 및 복학생의 학점 취득/인정 문제, 분반 학습 강좌의 평가 및 강좌 진행의 복잡성, 교수 확보 문제와 같이 예상되었던 문제점들 이외에도 오후 강좌에서 나타나는 낮은 출석률 및 강의 집중도, 계획과 다른 강좌의 운용문제, 그리고 일부 통합강좌에서 나타난 강의내용의 실질적 통합문제 등은 해결해야할 과제로 생각된다. The curriculum reform was undertaken at Kyungpook National University School of Medicine (KNUSM) to meet new educational objectives in order to cope with a rapid societal changes anticipated occurring in 21st century. The KNUSM Curriculum Development Committee was charged to formulate a new curriculum, which consisted of enhancement of patient-centered care based clerkship, integrated courses based on organ systems, problem-based learning, and additional teaching on social medicine, medical informatics and biomedical engineering. The philosophy of this curricular reform has been to modify methods of teaching medical students toward self-directed learning and student-centered. This whole concept was a drastic departure from the traditional lecturing. In the new curriculum, total of 180 credit courses, 4395 hours to graduate medical school were reduced to 170 credit courses, 4250 hours. As a part of the social medicine course, a 2 credit-hour course on patient-doctor relationship was taught and two credit-hour PBL tutorials were added to freshman, sophomore and junior years. In order to carry out this education reform, three new departments were inaugurated such as Biomedical Engineering, Medical Informatics and Medical Education. The school facility has also been improved during this preparatory period. The new curriculum has been implemented in 1999 academic year after approximately 4 years of preparatory period and annual faculty workshops have been held to monitor the progress of the reform and improve courses by evaluating impact of the change on both faculty members and students as well. The interim evaluation revealed several issues remained to be resolved. In conclusion, the acceptance of this reform was excellent from both faculty members and students although there have been continuous problem solving and adjustments necessary. The real assessment of the outcome of the reform requires many years to come and there has to be continuous monitoring of the progress and adjustment of curriculum are the pivotal of a success of the sort of education reform.

Purpose: Kyungpook National University School of Medicine initiated a pilot project to admit small number of qualified students who received BS degree or above in the field of sciences in 1996. This study was conducted to evaluate effectiveness of the pilot project. Methods: Students academic grades, outcome of their opinion surveys on adaptability to the school life, difficulties and problems from the classes of 1996 to 2001 were analyzed. Results: A total of 57 students were admitted to this program over the past 7-year period, 54.8% of them from natural science major and 36.8% from engineering. Students admitted with BS degree were performing above average in the class by % rank. There was no significant difference in academic performance between the natural science and the engineering major. Of 20 graduated, only one took career in basic medical science (physiology). The students thought undergraduate education was helpful in maturing personal characters than in knowledge or skill attainment. Conclusion: The achievement of medical students admitted after baccalaureate level was comparable to that of students with two years of premedical education.

본 논문에서는 정상류형 혈액 펌프의 일종인 축류형 혈액 펌프를 이용하여 혈액 펌프 시스템을 설계하였다. 이 시스템은 혈액 펌프, 신호 획득부, 인터페이스부, 신호 처리부로 구성되어 있고, 혈압과 심박수를 이용하여 혈압과 혈류량을 적절히 제어함으로써 좌심실의 기능을 보조할 목적으로 연구되었다. 전동 펌프가 회전할 때 생체내의 순환조건에 알맞도록 혈액 펌프의 회전수, 혈액 펌프에 걸리는 부하와 압력 정보를 적용하여 실험식을 만들어 제어에 이용하였으며 설계 제작된 모의 순환장치로써 실험한 결과 모의 혈관 내에서 적절한 혈압과 혈류의 제어가 가능하였고, 혈구의 변화량 실험 결과는 임시의 목적으로 사용가능함을 알 수 있었다. This paper outlines the development of a non-pulsatile axial flow type blood pump control system. By utilizing blood pressure and heart rate, this system can assist the left ventricle in controlling blood pressure and blood volume. The system is comprised of a blood pump, signal sensor, signal interface, and signal-processing component. A control algorithm is also proposed which can control non-pulsatile, continuous blood flow in the human circulatory system. To facilitate the control required fur non-pulsatile blood pump in a physiological system, an experimental control rule was developed utilizing ECG and blood pressure data, both of which are easily detectable variables in the bods. The system was then tested using a mock-up circulation system and we found that it is possible that this systems could be temporarily used in clinic.
