본 연구는 최신 기술을 활용한 미래 교육에 관한 사범대 학생들의 인식이 어떠한지를 조사하고,이러한 인식이 학과에 따라 어떻게 다를지를 파악하기 위한 목적으로 연구가 진행되었다. 본 연구의참여 대상은 경북에 위치한 4년제 대학의 사범대학에 재학 중인 학생들 110명으로, 설문지는 59문항으로구성되었다. 최신 기술 활용에 대한 흥미 관련 문항, 최신 기술 활용에 대한 저항 문항, 최신 기술활용에 대한 불안 문항, 향후 10년 동안 교육의 모습에 대한 예상을 알아보는 질문으로 구성되었다. 또한 전공 및 성별에 따른 차이를 분석하기 위해 본 연구에서는 분산분석, 빈도분석, 대응표본 t-test,독립표본 t-test이 사용되었다. 조사 결과 현재 사범대학생들의 최신 기술을 활용한 교육에 대한 인식에서 영어교육과와 윤리교육과의 전공 변수가 통계적으로 유의미한 차이를 나타냈다. 영어교육을 전공한 학생들은 특히 신경망 번역에대한 인지도가 매우 높은 것으로 드러났다. 반면, 윤리교육과 학생들은 최신 기술을 활용한 수업에대한 활용 의지가 낮았으며, 또한 최신 기술을 활용한 수업에서도 교사의 역할이 더욱 중요해질 것이라고응답하였다. 이러한 연구 결과를 고려할 때, 향후 사범대 학생들을 대상으로 하는 미래 교육에서는디지털 기술에 대한 교육과 함께 AI가 대체할 수 없는 교사가 가르치는 영역에 대한 역량 교육이통합적으로 강조되어야 함을 알 수 있었다. The current study aimed to investigate the perceptions of pre-service teachers regarding the integration of advancedtechnologies into future education and to examine whether these perceptions differ significantly based on the pre-service teachers'academic majors. The participants consisted of 110 pre-service teachers majoring in Ethics education and English educationat a university in Korea's Gyeongsang Province. A questionnaire comprising 59 items was administered, addressing aspectssuch as interest in the utilization of advanced technologies, resistance to their use, concerns about their application, andexpectations for the future of education over the next decade. Statistical analyses, including a paired t-test, an independent t-test,frequency analysis, and analysis of variance, were employed to examine differences based on variables of gender and major. The study revealed statistically significant disparities in the perceptions of pre-service teachers from distinct majors,particularly between English education majors and ethics education majors, concerning the incorporation of advancedtechnologies in education. English education majors demonstrated notably high awareness, particularly in the domain of neuralmachine translation. Conversely, ethics education majors demonstrated a lower inclination to embrace the use of advancedtechnologies in their instructional practices. Additionally, ethics education majors expressed the belief that the role of teacherswould become more pivotal in classes integrating these technologies. Considering these research outcomes, it becomes evidentthat future education for pre-service teachers should underscore comprehensive training in both digital technology educationand the development of competencies in areas where artificial intelligence cannot replace the role of educators.

폐암의 항암약물및 방사선치료후 절제수술;8례 보고

이두연 대한흉부심장혈관외과학회 1992 Journal of Chest Surgery (J Chest Surg) Vol.25 No.9

Eight patients with proven clinical stage Ill lung carcinoma of which six were epidermoid cell carcinoma and two were small cell carcinoma underwent concomitant radiation therapy and chemotherapy before surgical resection from March 1990 to February 1992 at the thoracic surgical department, Yongdong Severance Hospital, Yonsei University College Medicine The therapy consisted of more than one cycle of chemotherapy every 4 weeks and concomitant irradiation. Three to four weeks after chemotherapy and radiation therapy, the patient were reevaluated for thoracotomy and pulmonary resection. Two patients were found to have unresectable lesions and, radiosotopes were implanted to the remaining tumors. Three patients had complete pneumonectomies and two patients had pericardial penumonectomyo. Only one patient had complete pneumonectomy & concomitant resection of ribs attached to tumors with reconstruction of chest wall with Marlex mesh. Complete sterilization of lung tumor and mediastinal nodes proven histologically was achieved in 2 patients, without operative mortality. The median survival of all patients was eight months, but the median survival of survivors which lung tumor were completely resected completely and whose pathologic reports showed stage I or 0, was about 18 months to now. The overall result indicates some benefit from this preoperative chemotherapy and radiation therapeutic regimen in patients with advanced unresectable lung cancer.

The use of computed tomography of the chest in mediastinal staging of lung carcinoma lies the premiss that malignant lymph nodes are larger than benign ones. We have studied the size of mediastinal lymph nodes & the malignancy rate in 55 lung carcinomas from March 1990 to July 1992 at the Department of Thoracic and Cardiovascular Surgery, Yongdong Severance Hospital, Yonsei University College of medicine. The lack of relationship between the size of mediastinal lymph node and the probability of malignancy helps to clarify the limitations of the use of computed tomography in the staging of the mediastinum in lung carcinoma. There was no tendency for all malignant lymph nodes to be larger than benign nodes. To allow comparison with our data, malignancy rates for all lymph nodes larger than 10mm are 24.8% in sensitivity & benign rates for all lymph nodes less than 10mm are 96% in specificity. But all mediastinal lymph nodes larger than 30mm are metastatic lymph nodes in our cases. We are going to try to have thoracotomy for complete resection of lung carcinoma as possible as we can if there no evidence of contralateral mediastinal metastases of lymph nodes, even though there are large mediastinal lymph nodes in lung carcinoma.

황견에서 좌측 폐이식수술 및 폐동맥결찰 수술후 폐동맥압 변하에 관한 연구

이두연 대한흉부심장혈관외과학회 1994 Journal of Chest Surgery (J Chest Surg) Vol.27 No.5

We have performed left lung transplantation followed by ligation of right pulmonary artery in 14 dogs at the Chest Disease Research Institute, Yonsei University College of Medicine from May 1992 to February 1994. Excised left lung was perfused with 1500cc of 4$^{\circ}$C cold Euro-Collin`s[E-C] solution at a pressure of 30cmH2O through main pulmonary artery and preserved in 4$^{\circ}$C cold E-C solution for one hour. Left lung transplantation were proceeded in order of left atrium, left main bronchus, left pulmonary artery and right pulmonary artery ligation as usual method. The femoral artery and pulmonary artery pressures were monitored for more than 5 hours after the transplantations in 14 dogs. Six recipient dogs had elevated mean pulmonary artery pressure to greater than 30mmHg after the left lung transplantation and ligation of right pulmonary artery. The cause of elevated mean pulmonary artery pressure was due to inadequate preservation resulting in ischemic damage to donor lungs in 3 cases, and inadequate surgical techniques in 3 cases. Two recipient dogs without surgical complications died immediate post-operatively due to hemorrhagic shock. The bleeding focuses were LA anastomotic site in one case and femoral artery puncture site in another case. The remaining 6 recipient dogs showed mean pulmonary arterial pressure less than 30mmHg. However, one dog had spontaneous pneumothorax in post-operative 4 days, and another dog had rejection phenomenon in post-operative 5 days which was confirmed by pathologic findings of extracted transplanted lung. One dog succumbed of severe hemoptysis which was due to lung abscess with pin point stenosis of bronchial anastomosis in post-operative 38 days. In conclusion, elevated mean pulmonary arterial pressure greater than 30mmHg in immediate postoperative period can be due to inadequate preservation of extracted lung or poor surgical techniques. And the two dogs succumbed of hemorrhagic shock even though the mean pulmonary arterial pressure was less than 30mmHg. It is thought that careful preservation of the extracted donor lung in 4oC E-C solution and complete surgical techniques are the most important factors early and late complications.

순차적 양측 폐이식수술은 수술시 및 수술후 합병증이 매우 다양하며 수술후 결과가 매우 불량하다. 저자 등은 양측 폐 이식수술후의 혈역학적 변화를 연구관찰하고자 하였으며 수술후 발생할 수 있는 거부반 응을 예방하기 위하여 양측 폐재식수술을 선택,시행하였으며 폐동맥의 뒤틀림이나 협착, 좌심방내의 혈전발 생 등을 예방하기 위하여 폐동맥 및 좌심방 부위를 혈관감자로 폐쇄시킨 후 폐측 폐동맥의 전면을 절단하였고, 폐측 상하 폐정맥부위 좌심방 전면을 절단한 후 1시간동안 폐동맥 절단부위를 통해 PGEI이 함유된 I-C 용액을 주입하였고 1시간동안 I-C용액이 함유된 거즈를 이용하여 냉각을 유지하였다. 다시 5-0 prolene을 이 용하여 봉합하였다. 좌심방을 봉합할 때 내면이 외 전되게끔 everted suture 방법으로 봉합하였다. 주기관지는 완전 절단후 telescope방법으코 단단문합하였으며 폐재식 수술전후의 동맥혈 산소가스치, 대퇴동맥 및 폐동맥 압을 측정하여 비교하였으며 수술전후의 뚜렷한 혈역학적 변화는 없었다. 절단 결찰된 폐는 PcEl이 함유된 I-c용액을 폐동맥으로 4o cmHlo 압력으로 Is ~h입분의 속도로 총량이 70 mfg되도록 주입하\ulcorner으며 그후 1시간동안 냉각된 I-C용액이 함유된 거즈를 이용하여 절단된 폐를 감싸서 냉각저류보관하여 허혈성 손상을 예방함으로써 수술수기에 대한 합병증이 없는한 양측 폐 이식수술후 성 적은 양호할 것으로 생각된다. Sequential bilateral lung transplantation may result in a variety of perioperative and postoperative complications, showing high perioperative morbidity and mortality rates. This research was performed to investigate the hemodynamic changes in adult mongrel dogs after bilateral reimplantation, two methods preferred for avoiding or minimizing graft rejection. The anterior portion of the pulmonary artery and the left atrium proximal to the superior and the inferior pulmonary veins were resected out and then re-anastomosed one hour later to prevent torsion or stenosis of the anastomotic site and the formation of a thrombosis in the left atrium. An everted suture technique was employed for the left atrium; An hour after the division, however, the main bronchus was tightly anastomose by interrupted sutures of No. 4-0 prolene in a telescope method. A modified I-C solution mixed with PGEI was infused into the cut portion of the pulmonary artery at the rate of 15 mllkglmin and at a pressure of 40 cmH20 for a total dosage of 70 mlfkg in order to preserve the transected lung. Topical cooling using wet gauzes soaked with cold I-C solution was performed for one hour to prevent ischemic lung injury. The above procedures are considered to be beneficial for achieving a satisfactory outcome for bilateral lung reimplantation.

We performed post-operative hemodynamic evaluation and lung perfusion scan after left lung transplantation in dog. The heart & lungs were extracted from donor dog while the both lungs were flushed with 4oC Euro-Collin`s solution after heparinization & infusion of prostaglandin E1.In the recipient dog, anastomosis of the left atrial cuff was performed by continuous 4-0 Prolene everted suture, and bronchial anastomosis by telescope method with 4-0 Prolene continuous suture. The end-to-end anastomosis of left main pulmonary arteries was performed with continuous 6-0 Prolene suture. After closure of left thoracotomy incision, the lung perfusion scan was performed post operative 2 days for evaluation of the function of the transplanted lung which showed good perfusion. The dog was sacrificed in the post-operative 5 days for autopsy.

Successful correction of the partial form of atrioventricular[AV] canal is now readily achievable. The most challenging technical features of this anomaly are the associated mitral valvular deformity and the frequent inability to obtain mitral competence. Residual mitral incompetence after repair of mitral cleft figures importantly in the causes of early and late failure. So, accurate and complete repair of the mitral valve cleft might be important. Determination of residual severe mitral regurgitation after repair is desirable to permit mitral valve replacement at the time. We have experienced one case of severe mitral regurgitation which was occurred 6 months after repair of partial form of A-V canal [ASD primum] in 22 years old virgin. Pre-op. left ventriculogram revealed severe mitral regurgitation in this patient. We preferred to perform mitral valve replacement with St. Jude valve in this patient at March 1984. Post-op. course was uneventful to now for 5 months and we report this case, review and discuss the literatures.

Between May 1979 and April 1989, 213 patients with esophageal injuries visited the Department of the Thoracic and cardiovascular surgery Department, Yonsei University College of Medicine. There were 159 non perforated esophageal injuries accompanied by hematemesis, and 54 perforated esophageal injuries. The causes of non perforated esophageal injuries were Mallory-Weise Syndrome [%], corrosive esophagitis [54], esophageal carcinoma [4], foreign bodies [2], sclerotherapy due to esophageal varices [3]. The causes of perforated esophageal injuries were esophageal anastomosis[13], malignancies[17], esophagoscopy or bougienage[5], chest trauma[5], foreign bodies[5], paraesophageal surgery[3], others[6] In esophageal perforation due to foreign bodies, esophagoscopy or bougienage, there were 6 cervical esophageal perforations and 9 thoracic esophageal perforations. There were no mortalities in the treatment of the cervical esophageal perforations and 5 deaths resulted in the treatment of 9 thoracic esophageal perforations. And four of six patients with thoracic esophageal perforations died in the initiation of treatment over 24 hours, after trauma. There were another 12 deaths in the patients with chest trauma, malignancies or chronic inflammation except esophageal injuries due to foreign bodies or instruments during the hospital stay or less than 30 days after esophageal injuries. One patient with esophageal carcinoma died due to bleeding and respiratory failure after irradiation. Another patient with esophago gastrostomy due to esophageal carcinoma died of sepsis due to EG site leakage. One patient with a mastectomy due to breast cancer followed by irradiation died of sepsis due to an esophagopleural fistula. Two patients with Mallory-Weiss syndrome died; of hemorrhagic shock in one and of respiratory failure due to massive transfusion in the other. One patient with TEF died of respiratory failure and another died of pneumonia and respiratory failure. One patient with esophageal perforation due to blunt chest trauma died of brain damage accompanied with chest trauma.

Segmental resection or wedge resection of the lung and direct cutting across of bronchi frequently results in postoperative airleaks or bronchopleural fistula in some cases. Many methods have been devised to handle air leak problems by oversuturing the raw edges, the application of pleural onlay flaps, the use of cautery or tissue adhesives, but these still has not solved the problem of air leaking from raw surfaces of the lung with only partial successful we have tried the use of histoacryl to closure the raw surface of the resected lung and compared it’s results with of the closure with chromic catgut sutures in cats from May 1989 to Jan. 1990 at the department of the thoracic and cardiovascular surgery, Yonsei University, College of Medicine. Ninety lobe of the lungs were used in this study and forty nine of which have been divided segmentally and closed with histoacryl on the raw surfaces. Forty one of which have been divided segmentally and closed with sutures using chromic catgut for control. There were air leakages in twelve cases among 49 cases with applying histoacryl and airleak were in two cases among 12 cases with reapply histoacryl, But there were air leak in two cases among 41 cases with sutures using chromic catgut and airleak were in one case among with resutures using chromic catgut.

심한 빈혈증상을 동반한 거대한 식도주위허니아 치험 1예 (Belsey Mark V 수술치험)

Paraesophageal hiatus hernia represents a rare hiatal hernia that are treated surgically. The completely asymptomatic paraesophageal hernia often does not reach the clinician or surgeon. But the presence of a symptomatic paraesophageal hernia is sufficient indication for surgery. The paraesophageal hernia may be approached either transthoracically or transabdominally. The general technique is essentially the same, whichever route is used. From either transthoracic or transabdominal approach, following reduction of the viscus and elimination of the sac, the diaphragmatic opening is then closed with interrupted heavy dacron or silk sutures in paraesophageal hiatus hernia. But if the phrenoesophageal membrane often is destroyed when the esophagogastric junction and the distal esophagus have been mobilized, it becomes important to fix the esophagogastric junction below the diaphragm, so that it does not slide through the hiatus and produce a sliding-type hiatus hernia in future. We have experienced one case of paraesophageal hiatus hernia which was accompanied with severe anemia in child. We preferred to approach through left thoracotomy incision and then pushed down the stomach into the abdominal cavity with complete excision of the hernial sac. We employed Belsey Mark V procedure using of Teflon felt pledgets with the mattress sutures against development of sliding-type hiatus hernia in postoperative period. postoperative course has been uneventful and good for about 3 months to this time.
