The bronchopulmonary sequestration is a term used to describe an area of embryonic lung tissue supplied by an anomalous systemic artery. Two forms are recognised -extralobar and intralobar- with different clinical presentations. We have experienced a case of aspergillosis within an intralobar sequestration. The patient was 32 year-old female and had no specific complaints. The lung mass containing cystic lesion was found incidentally and confirmed to be intralobar sequestration on the operative field which showed aberrant artery in the inferior pulmonary ligament. The right lower lobectomy was done

최근 IC 설계 및 제조 기술의 급격한 진보에 따라 PC 보급이 포화상태에 이르면서 가전제품으로서 첨단을 자랑하던 PC가 일반 가정에서 TV의 보급률과 비슷해지며 대중화에 되어가고 있다. 이에 따라 임베디드 시스템 기술이 PC뿐 아니라 정보 가전, 정보 단말, 통신 장비, 항공, 군사, 물류, 금융, 차량, 교통, 사무 사업 제어 의료 등 전 분야에 걸쳐 다양하게 적용되고 있는 실정이다. 본 논문에서는 이러한 임베디드 시스템에서의 여러 디바이스를 효율적으로 관리하기 위한 한 가지 기법으로 프레임버퍼를 이용한 디바이스 통합 제어 모듈을 설계 및 구현하였다. 본 논문에서 제안하는 기법은 임베디드 시스템에서 사용자 인터페이스로만 부각되던 LCD 화면을 통해서 임베디드 시스템의 각종 디바이스를 진단하고 제어할 수 있게 하여 특별한 외부 장치 없이 곧바로 디버깅이 가능하도록 하였다.

자가 폐동맥 판막을 이용한 대동맥 판막 치환술을 항응고제 복용이 필요없고 내구성이 어느정도 입증되어 늘어나고 있으나, 자가 폐동맥 판막을 이용한 승모판막 치환술은 국내에 보고된 예가 없다. 53세 여자 환자로 류마티스성 승모판막 협차가 및 폐쇄부전, 삼첨판막 폐쇄부전, 만성 심방 세동, 그리고 자회전 관상동맥의 폐색등으로 진단받은 환자에서 자가 폐동맥 판막을 이용한 승모판막 치환술 및 maze 술식, 삼천판막 성형술, 관상동맥 우회수술을 시해하였다. 수술후 특별한 문제없이 회복하였으며 술후 시행한 심초음파 검사상 자가 폐동맥 판막의 이상 소견없이 잘 기능하고 있으며 항응고제 복용없이 잘 지내고 있다.

We report a case of a 40-year-old woman whose right ventricular out-flow tract was moderately obstructed by a heavily calcified pericardial ring. It was passing over the base of pulmonary artery and mid-portion of left ventricle but the other parts of the pericardium was mildly fibrotic. The pericardium and calcified ring were completely removed under cardiopulmonary bypass. The patient was recovered uneventfully and we could not find the specific cause of calcified pericardial ring.

Primary cardiac tumors are rare, and primary malignant cardiac tumors are even rarer. Of these, angiosarcoma was uncommon, Surgical resection of the tumor was very difficult because symptoms were nonspecific and did not become present until the tumor had advanced. A 15-year-old male patient was diagnosed with primary cardiac angiosarcoma by microscopic examination under surgery and underwent resection of the tumor, which compressed and obstructed the right atrium. He was discharged from the hospital after 15 days without any problems.

본지가 학술위원회의 회원보수교육사업의 일환으로 84호(76년 7, 8월호)부터 ''지면을 통한 보수교육''난을 마련하여 각 분야별 시리즈로 엮어 나왔읍니다만, 이번호 부터는 출판위원회가 ''보건간호학''편을 기획하면서 ''1차 건강관리를 위한 보수교육''으로 그 명칭을 마꿔 실제로 처음 내소(원)한 환자에 대해 간호원에 의해 행해지는 진단에서부터 신체의 각 기관의 검사에 이르기 까지를 보다 실제적이고 구체적인 내용으로 엮어보고자 하였읍니다. ''건강력 파악법''에 대해 연세대학교 조원정 조교수가 맡아 주셨고, ''간호원에 의한 건강사정법''에 대한 개괄적인 내용은 연세대학교 김조자 조교수가 맡아 주셨읍니다. 이어서 간호원에 의한 건강사정의 각 기관별 내용을 최근 $2\~3$년간에 걸쳐 A.J.N이 특별기획으로 수록해온 내용을 채택하여 수회에 나누어 번역소개 할 예정입니다.

Falls are fatal accidents that occur more than 420,000 times a year worldwide. Therefore, to study patients with falls, we found the association between extrinsic injury codes and principal diagnosis S-codes of patients with falls, and developed a prediction model to predict extrinsic injury codes based on the data of principal diagnosis S-codes of patients with falls. In this study, we received two years of data from 2020 and 2021 from Institution A, located in Gangneung City, Gangwon Special Self-Governing Province, and extracted only the data from W00 to W19 of the extrinsic injury codes related to falls, and developed a prediction model using W01, W10, W13, and W18 of the extrinsic injury codes of falls, which had enough principal diagnosis S-codes to develop a prediction model. 80% of the data were categorized as training data and 20% as testing data. The model was developed using MLP (Multi-Layer Perceptron) with 6 variables (gender, age, principal diagnosis S-code, surgery, hospitalization, and alcohol consumption) in the input layer, 2 hidden layers with 64 nodes, and an output layer with 4 nodes for W01, W10, W13, and W18 exogenous damage codes using the softmax activation function. As a result of the training, the first training had an accuracy of 31.2%, but the 30th training had an accuracy of 87.5%, which confirmed the association between the fall extrinsic code and the main diagnosis S code of the fall patient.

Conventional studies of Computer Assisted Instruction(CAI) and Intelligent Tutoring System(ITS) have been general patterns to solve problems, so to solve specialized problems, the learner which has the attitude of passiveness should to solve problems including unnecessary processing to the need of the system. Consequently, those are not support the process of creativity and individual problems for the learner to solve the fractional number operations as this study. This study is the design and implementation of ITS on the fractional number addition and subtraction for the supplementary student. Our system can diagnosis mistakes of learning and guide the student to know their errors of learning process automatically And our system assist the learners to study with self-initiative learning, replacement their lacking of learning and control the process of fractional addition and subtraction operation with creativity according to their level. We showed that this system had improved problems of lacking care to supplementary student result in are not enough teachers involved their school and that the learner had achieved the higher learning effect according to the improved self-initiative learning causing this system.

The patient was an eight-year-old female. She was diagnosed as dilated cardiomyopathy. She was supported with bi-ventricular assist because of heart failure for 15 days. After 7 days, she was suffered from prerenal type ARF and support with continuous veno-veno hemodyalisis(CVVHD). And then heart transplantation was performed, heart donor's blood type was A. Immune suppressants were used after due consideration for renal toxicity. ARF was resolved on post operative $14^{th}$ day. She was discharged on post operative $52^{nd}$ day without any specific post operative complication. She has been followed up without any immune rejection reaction upto 14 months.

Prosthetic valve endocarditis(PVE), although uncommon, is associated with significant mortality if the infection spreads into the paravavular structures with later abscess formation. However, combined antibiotic and surgical treatment is often successful. Accurate diagnosis by on echocardiography, effective myocardial protection during operation and increased surgical experience have improved the short-term and long-term outcomes for patients with PVE. A 35-year-old male had a history of replacement of aortic and mitral valve, and tricuspid annuloplasty on August 1994, was admitted due to sudden onset of aphasia, leftward deviation of both eyeballs and spiking fever and diagnosed of having PVE by echocardiography. Reoperation was done after 6weeks of antibiotic treatment. On the operative field, we could notice circumferential vegetation along aortic valve annulus, paravalvular leakage and abscess pocket. The mitral valve amlulus was healthy. The patient underwent redo aortic valve replacement using cryopreserved aortic homograft after radical debridement of infected issue. During the follow up of 7 months period the homograft was well functioning without recurrence of symptoms.
