To obtain basic data used for establishing the criteria of deterioration in renovation of educational facilities, current problems of material and method and quality improvements were examined. In this study, the elementary schools built 20 and 70 years ago were unintentionally chosen and studied. With the data of the repair of old educational facilities, the results are as follows. The First problem is that the construction priority which was based on non-experts decision. The Second problem is that maintenance method which changes the materials after their life was ended. So, refer to remodeling of educational facilities, the selections of proper materials and methods to use of each function were main object in this study.

This paper studied Lee Han-Choel's career who was known as the first Korean who had participated in several survey and repair projects of Korean historic buildings as a field engineer during the Japanese colonial era. This paper investigated documents and drawings to find out what he had done specifically in the field, and distinguished the records he had written by handwriting comparison method. In addition, the author analyzed the contents of the articles he published and clarified their significance in Korean architectural history. Through this study, the author expected to clarify Lee's historical status as the first Korean modern expert in the field of historic building conservation, and to supplement the research for the history of Korean during the Japanese colonial era.

To analyze the states of operation of radiotherapy facilities in the period from 1979 to 1992 and to get the base for efficient operation and maintenance of the radiotherapy facilities. Data on the records of annual number of patients operated by each facility; span of suspension of operation, the cost and span of repairing, and parts of oui-of-order in the period from 1979 to 1992 were analyzed. We made a comparative analysis of average annual number of patients, annual span of the suspension of operation, annual cost ratio of repair, span of repairing per break down, and total number of broken parts. We could get following annual number of patients(day), span of the suspension of span ($\%$)(day). annual cost ratio fo repair($\%$), span of repairing per break down(Min-Max, day), and number of broken parts from this analysis. 1. Cobalt unit (Picker C-9) : 10,389(43), 0.4(0.83) 0.07, 1hr-2, 3 2. Linac(Clinac 6/100) : 11,492(50), 4.0(9.57), 0.98, 1hr-30, 12 3. Linac(Clinac 18) : 9.115(44), 12.7(30.5), 3.54, 1hr-108. 41 4.

The rate of operation of Cobalt unit($99.6\%$) was higher that of Linear Accelerators ($87.3\%$). The rates operation of Simulator and RTP computer were very close to that of Cobalt unit. 2. In order to raise up the working ratio of accelerator. it is desirable that we keep our engineer to learn a sufficient technical skill and the equipment agent to stock sufficient spare parts. 3. In order to maintain Linear Accelerator efficiently, it is desirable to have annually $2.3\%$ of the purchase price of equiment for repairing.

A 1/4-scale two-bay eight-storey reinforced concrete frame was tested on shaking table. Initial shaking table tests were carried out through a set of real seismic excitations to investigate the seismic behavior of the RC frame. Subsequently, the damaged frame was repaired using epoxy injection technique, and then subjected to the tests with the same records. The purpose of this study was to investigate experimentally the dynamic characteristics, cracking pattern and lateral inter-story stiffness of RC frames using epoxy injection technique. The test results indicate that epoxy-injection technique appears to be a satisfactory method for repairing earthquake-damaged structure.

많은 공동주택의 공급에도 불구하고 정부의 정책은 주택의 건설, 공급위주로 주택정책을 시행함에 따라 주택의 유지관리 측면에서는 소홀히 하여왔다. 그 결과로써 주택자원의 이용과 주거생활에 불편을 초래하고 있다. 따라서 본 연구에서는 현행제도와 현 조사실태의 수선주기를 비교, 분석하여 개선방안을 제시하고 있다. 분석 결과 적정시기의 적합한 수선을 하는 것이 장기적으로 볼 때 건물 노후화를 늦출 수 있고 건물의 기능을 초기와 비슷하게 유지시킬 수 있음을 알 수 있었다. 따라서 효율적인 수선 유지 관리를 통하여 건물의 노후화와 기능을 지연시킬 수 있을 것이다.

조선 말기 방한용 깔개인 모담(毛毯)이 창덕궁 성정각의 해체 공사 중 발견되었다. 문헌기록에 비해 현전하는 조선시대 모직물 유물이 많지 않아 유물로서 가치가 높다. 특히 1907년 창덕궁 성정각을 수리한 기록이 있어, 모담은 19세기 말 또는 20세기 초에 제작된 것으로 생각된다. 출토 모담은 자적색 계열의 바탕 직물로 위에 황색, 홍색 등으로 선염한 색사를 표면에만 삽입하여 문양을 시문하였다. 모담의 식서부분은 S연의 면사가 확인되었으며, 지경사는 Z연의 황마사, 지위사는 S연의 황마사, 문경사는 S연의 모사를 사용했다. 특히 무늬는 루프파일의 색사로, 색사의 경계면에서 일부 컷 파일이 확인되나 지위사로 고정되어 표면에 거의 드러나지 않는 다. 황마사와 모사를 사용한 것은 18세기 중엽 유럽의 브뤼셀 카펫의 영향을 받은 것으로 짐작된다. 모담의 문양을 밝히는 데 한계가 있으며 다만 문양이 부분적으로 반복됨을 알 수 있다. 이상의 연구내용을 도출하기 위해 문헌과 회화자료 외에 현미경 분석, 적외선 분광분석을 실시하였다. 또한 유물에 사용된 염료를 밝히기 위해 색도측정을 토대로 자외-가시광 분광분석을 실시하여 천연 염색한 직물 샘플에 대한 교차분석을 시도하였다. 그 결과 모담의 녹색 모사는 쪽을 사용하지 않았으며, 자적색의 바탕조직은 소목으로 염색한 것으로 추정할 수 있다.

Background The most common cutaneous malignant masses are basal cell carcinoma (BCC) and squamous cell carcinoma. The predominant site of a malignant mass is the face, which has many opportunities to be exposed to ultraviolet radiation. However the predilection sites of malignant masses have been equivocal due to the use of general regions, rather than anatomical landmarks, in surveys. A facial esthetic unit is an anatomical site classified as an area of similar facial contour characteristics that can be distinguished from other areas. The purpose of this study is to determine widely accepted anatomical landmarks using the esthetic unit. Methods We retrospectively analyzed 118 cases of malignant masses in our clinic from January 2005 to October 2012. We evaluated the patients' age, gender, and predilection site of the malignant mass by esthetic unit through pathology, medical records and patient photographs. We mapped the occurrence site of the malignant mass on schematic drawings of the esthetic units. Results Most of the malignant masses were BCC. The ratio of males to females was 1:1.41. The frequent predilection site of a malignant mass was on the nasal unit (33.1%), followed by the buccal unit (11.0%). Primary closure was the most common method of repairing a surgical defect (38.9%), followed by a local flap (35.5%). Conclusions This review described the relationship between clinical characteristics and esthetic units by proposing objective predilection sites for malignant masses, which can be used commonly as a framework in the study of malignant masses by unifying equivocal occurrence sites.

Background Nonabsorbable sutures are favorable for repairing flexor tendons. However, absorbable sutures have performed favorably in an animal model. Methods Two-strand sutures using the interlocking modified Kessler method with polydioxanone absorbable sutures 4-0 were used to repair completely ruptured flexor tendons in 55 fingers from 41 consecutive patients. The medical records of average 42 follow up weeks were analyzed retrospectively. The data analyzed using the chi-squared test, and Fisher's exact test was used for postoperative complications. The results were compared with those of other studies. Results Among the index, middle, ring, and little fingers were injured in 9, 17, 16, and 13 fingers, respectively. The injury levels varied from zone 1 to 5. Of the 55 digits in our study, there were 26 (47%) isolated flexor digitorum profundus (FDP) injuries and 29 (53%) combined FDP and with flexor digitorum superficialis injuries. Pulley repair was also conducted. Concomitant injuries of blood vessels and nerves were found in 17 patients (23 fingers); nerve injuries occurred in 5 patients (10 fingers). Two patients had ruptures (3.6%), and one patient had two adhesions (3.6%). Using the original Strickland criteria, all the patients were assessed to be excellent or good. Also, fibrosis and long-term foreign body tissue reactions such as stitch granuloma were less likely occurred in our study. Compared to the Cullen's report that used nonabsorbable sutures, there was no significant difference in the rupture or adhesion rates. Conclusions Therefore, this study suggests that appropriate absorbable core sutures can be used safely for flexor tendon repairs.

장흥 보림사는 신라 경덕왕 18년(759)에 원표(元表)대사에 의해 화엄종찰로 개창되었으나 체징(體澄)이 헌안왕 2년(858)에 가지산사로 이석함으로서 선종사찰의 중심 도량으로서 지위를 확보하게 되었으며, 조선시대에 들어와 대단히 번창하였던 사찰이다. 이 연구는 1995년 장흥 보림사의 사천왕상에서 발굴된 복장불서 가운데 보물 제745-9호로 지정된 "월인석보(月印釋譜)"(권25)를 대상으로 서지학의 관점에서 지류문화재의 보수 및 보존처리 과정을 다룬 연구 논문이다. 연구 결과는 다음과 같다. 보존처리 전 형태적 특징을 보면, 책의 크기는 가로 22cm, 세로 32.3cm, 책의 두께는 2.8cm, 오침안정버법(五針眼訂法)의 선장(線裝)형태를 유지하고 있으며, 총 142장(3~144장)이 발견되었다. 책의 상태는 사천왕상에 빗물이 스며듦으로서 책의 일부분이 규칙적으로 얼룩져 있을 뿐만 아니라 앞부분과 뒷부분의 장은 부식으로 인한 손상이 심한 상태며, 중앙부분은 비교적 양호한 상태를 유지하고 있음이 확인되었다. 보존처리 과정은 1) 제1차 세척과정, 2) 판본 보완 및 보수 과정, 3) 제2차 세척 및 보존처리 과정, 4) 재단 및 제책과정, 서투 및 표갑의 제작 등으로 나누어 실행하였다. 보존처리 후 책의 외형은 가로 22.5cm, 세로 32.7cm, 두께 3.2cm로 가로 0.5cm, 세로 0.4cm, 두께 0.4cm 등의 외형적 변화가 발생하였으며, 장수(張數)는 총 151장으로 표지를 포함하여 9장의 매수가 증가하였다.
