본 연구는 1960년대 정부의 지원 정책 부재가 우리나라 학교도서관 발전에 미친 영향에 대하여 고찰하고자 한다. 특히 1960년대에 학교도서관의 확산에도 불구하고 실효성 있는 <도서관법> 제정이 동반되지 않음으로 인하여, 이후 학교도서관이 쇠락할 수밖에 없었던 과정을 주로 살펴보았다. 이 논문은 그간 정부의 지원 정책에서 소외되어 온 학교도서관 역사를 되돌아보고, 어느 때보다 제도적 지원이 절실한 우리나라 학교도서관이 과거의 전철을 밟지 않도록 하는데 의의가 있다. This study examines the effect of the absence of a government support policy on the development of school libraries. Specially this article focuses on the rise and fall of school library in 1960's over the making first Library Law. It is meaningful that our school libraries, which have been alienated due to the lack of government polices, are not following in the footsteps of the past, as they are in need of state support.

Congenital coronary arteriovenous fistula is uncommon disease, and was first described by Krause in 1865. About 20% of the cases, it associates additional congenital heart diseases. A 5-year-old female patient was diagnosed as coronary AV fistula with VSD, and was taken surgical correction under cardiopulmonary bypass. VSD was small and subarterial in type, and the fistula was dilated as adult thumb tip size at its distal portion. VSD was closed directly through the pulmonary arteriotomy and the aneurysmal dilation was opened vertically, then it was obliterated using 5-0, 6-0 prolene continuous suture fashioning into a long slender tube. Postoperative course was uneventful.

Tumors of the mediastinum are usually classified according to their location in the anterior, middle, or posterior mediastinum. Mediastinal teratomas are characteristically located at anterior mediastinum with only rare incidence in the posterior mediastinum. Two cases of posterior mediastinal teratoma were experienced recently, in the department of thoracic surgery, Seoul National University Hospital. The incidence of posterior mediastinal teratoma was 4.2% among 48 mediastinal teratomas in our experience. Two cases are all benign teratoma located at right posterior costophrenic angle, and histologically showed tissues from three germ layers including bone and fat.

Cathode materials and their precursors are prepared with transition metal solutions recycled from the the waste lithium-ion batteries containing NCM (nickel-cobalt-manganese) cathodes by a $H_2$ and C-reduction process. The recycled transition metal sulfate solutions are used in a co-precipitation process in a CSTR reactor to obtain the transition metal hydroxide. The NCM cathode materials (Ni:Mn:Co=5:3:2) are prepared from the transition metal hydroxide by calcining with lithium carbonate. X-ray diffraction and scanning electron microscopy analyses show that the cathode material has a layered structure and particle size of about 10 ${\mu}m$. The cathode materials also exhibited a capacity of about 160 mAh/g with a retention rate of 93~96% after 100 cycles.

본 연구에서는 이용량이 기하급수적으로 증가하는 A대학 기관리포지터리(IR)의 자료 유형별 이용통계와 이용자가 A-IR에 접근하는 접근경로의 변화 추이를 분석하였다. 특히, 접근경로의 변화 추이에 초점을 맞추어 다양한 노출경로의 확보가 A-IR 이용확산에 기여한다는 것을 검증하였으며, SNS 등 시대적 소통방식이 A-IR의 접근경로로 활용된다는 것도 확인하였다. 이를 통해서 향후 기관리포지터리를 활성화하는 노출경로의 다양화 등 운영방향을 제시하고자 하였다. In this study, the use statistics by type of data in the A university of a Institutional Repository(IR) with exponential growth in usage and the trend of changes in the access path for users to access A-IR were analyzed. In particular, it was verified that securing various exposure paths contributed to the spread of A-IR by focusing on the change in the approach path, and also confirmed that the method of communication between the ages, such as SNS, is used as the approach path of A-IR. Through this process, the company was planning to suggest the direction of operation, including diversification of exposure paths that activate the institutional repository.

The records of 268 patients, who were diagnosed as spontaneous pneumothorax during the period 1975 to 1984, treated at the department of thoracic and cardiovascular surgery, Hanyang University Hospital, were reviewed retrospectively to evaluate the effect of surgical intervention on each indications. Of these,.61 patients [22.8%] were taken operation to treat the pneumothorax after closed thoracostomy. We have classified the 61 patients to evaluate the therapeutic effect on each indications. And the therapeutic effect is based on the chest tube indwelling days. The results were as follows: 1. The chest tube indwelling days of the group who were taken closed thoracostomy only was average 14.13*9.17 days [range 5-66 days], and that of the group who were finally taken the thoracotomy after closed thoracostomy was 21.85*12.30 days [range 5-55 days]. 2. The indications of thoractomy were thoracoscopic findings, recurrence and continuous air leakage. 3. The chest tube indwelling day of the group who was taken thoracotomy by thoracoscopic findings was average 11.67*6.51 day, that was relatively short compared to those of the other groups. 4. The continuous air leakage group after closed thoracostomy was subdivided into three subgroups, continuous air leakage in 1st attack, thoracoscopic findings in 1st attack, and recurrence. 5. Of these, the chest tube indwelling day of the subgroup, who was taken operation by thoracoscopic findings, was 21.33e8.26, that was relatively short compared with those of the other subgroups. We use the thoracoscope as excellent diagnostic tool to detect the operation indication in the spontaneous pneumothorax patients. And we gain the benefits to shorten the chest tube indwelling days and admission days, and also to protect the recurrence.

A 51 year-old male was admitted with the chief complaints of swallowing difficulty and pain on neck and upper chest for 2 months prior to admission: He was taken biopsy under esophagoscopy, and the result was squamous cell carcinoma. Preoperatively we studied the esophagogram and chest CT. On these, we found the main appreciable mass at midesophagus easily. But, we missed the upper cervical unexpected mass. So we performed the esophagectomy and lymph node dissection from upper clavicle level to the esophagogastric junction by thoracic approach as wide as possible, and cervical esophagostomy and feeding gastrostomy also. At that evening we reviewed the studied films in detail, and we found another mass lesion at C4-C6 level of cervical esophagus. We performed the 2nd operation e.g. cervical esophagectomy on next morning without hesitation. Between these two masses, there was almostly normally looking skip area grossly. The squamous cell carcinoma of the esophagus could be multicentric in character and may have skip area. But, we heard little reports until now. The two masses could be different in origin or be same probably by submucosal spreading. Anyway, it was an alarming case to the surgeon not to neglect the another possible lesions in squamous cell type. Postoperative course was uneventful, he took G-tube feeding with no problems on 7th postoperative day. Now he took the postoperative irradiation at out patient department.

Despite low mortality and excellent long-term results after repair of Tetralogy of Fallot, certain associated anomaly such as single pulmonary artery continues to be told to have a high operative mortality and morbidity, and there is still some debate on appropriate surgical intervention. During the 4 year period from 1981 to 1984, surgical repair was performed on 5 patients with tetralogy of Fallot and congenital [4 cases] or acquired [1 case] absence of left pulmonary artery. Previous left pneumonectomy had been performed in the patient with acquired absence of a pulmonary artery. Transannular patch or RVOT patch alone with or without pulmonic valvotomy was used with some modifications to reduce pulmonic insufficiency in individual patient. In contrast with previous reports, all patients survived operation and have exhibited marked symptomatic improvement without pulmonic valve insertion nor valved conduit.

The case of a patient with abnormal position of the atrial septum resulting in a left atrium with two atrioventricular valves and a disconnected right atrium is presented with review of related articles. Anatomic details showed atrial situs solitus and a left sided cardiac apex. The right atrium received both venae cavae and a coronary sinus. No AV valve was found in the right atrium, and the floor of this chamber was placed above the posterior wall of right ventricular chamber. The atrial septum with secundum ASD was displaced to right anteriorly at its lower portion and inserted to right of tricuspid annulus. The tricuspid and mitral valve configuration was that of so-called partial ECD, i.e. mitral cleft with large anterior mitral leaflets. The ventricular septum was intact and both ventricular chambers were equally well developed with normal relationships. Surgical repair of this anomaly was performed by resecting the abnormally positioned lower part of the atrial septum, repairing the cleft of the anterior mitral leaflet, and septating the atrium for diverting the systemic and pulmonary venous blood to RV and LV, respectively.
