Boerhaave's syndrome is a very fatal condition occuring esophageal rupture during emesis and has the worst prognosis of the esophageal perforation. From May 2007 to March 2012 11 patients underwent surgical treatment for Boerhaave's syndrome at Inje University Sanggye Paik Hospital. There were 11 males whose mean age was 49.9 years ranging from 42 to 59. 2 cases of primary closure was performed and 9 cases of anastomosis using EEA (Esophago-Enteric Anastomisis) stapler. Mean operation time was 154.4 minutes and one patient who undergone primary repair died because of mediastinitis and sepsis on $35^{th}$ post-operative day. There was no leakage at other patients. Post-operative complication was one operative wound infection and one post-operative bleeding which was treated completely. Surgical treatment for Boerhaave's syndrome using EEA stapler is simple and effective technique but further studies with large number of cases should be carried out for better outcome.

The efficacy of a technique for the rehabilitation and strengthening of RC beam-column connections damaged due to cyclic loading was investigated. The repair mainly uses epoxy resin infused under pressure into the damaged region to retrieved back the lost capacity and then strengthening using fiber reinforced polymer (FRP) sheets for capacity enhancement. Three common types of reduced scale RC exterior beam-column connections namely (a) beam-column connection with beam weak in flexure (BWF) (b) beam-column connections with beam weak in shear (BWS) and (c) beam-column connections with column weak in shear (CWS) subjected to reversed cyclic loading were considered for the experimental investigation. The rehabilitated and strengthened specimens were also subjected to similar cyclic displacement. Important parameters related to seismic capacity such as strength, stiffness degradation, energy dissipation, and ductility were evaluated. The rehabilitated connections exhibited equal or better performance and hence the adopted rehabilitation strategies could be considered as satisfactory. Confinement of damaged region using FRP sheet significantly enhanced the seismic capacity of the connections.

후두의 Anterior glottic web에 대한 수술적 치료방법은 1924년 Haslinger가 처음으로 Web의 성공적인 Correction예를 보고한 이래 1935년 Iglauer, 1950년 Mc Naught, 1969년 Pennington, 1970년 Montgomery등이 각기 다른 치료법을 소개하였으나 그 치료목적이 전연합부의 상피화와 동시에 Denuded Vocal Cord에 형성되는 유착을 방지하는 데에 있었다. 저자등은 최근 후두유두종 3례에서 2∼3회의 제거술후에 유발된 Anterior glottic web를 경험하여 Stainless Steel Plate를 이용한 Keel을 제작하여 사용한 결과 만족할 만한 결과를 얻었기에 문헌적 고찰을 가하여 보고하는 바이다.

Global warming is affecting all industries, and has been applied very quickly in the energy sector. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a square solar flower of the biological mother was developed by using TRIZ technique(6SC).

Metro Subway System is widely known as the leader of public transportation in a metropolitan area. The signal interlocking is one of the most important organs that plays a major role in the system. By improving the quality of signal lights on the traffic system and keeping its maintenance on a high level will not only repair the current state, but it will also let the LED type signal semi-permanent. The device, which underwent a process of fine manufacture establishment and a close examination, obtained a patented article (2004, as a new device). Utilizing the equipment with cautious preservation on the system will enhance the current state of the signal device. Especially, the test for improvement and development based upon the technique that decreases the frequency of defect produced will further precipitate its efficiency. With authorization of imposing the LED lights on production, installment, and investigation of the system, the newly made equipment will bring improvement to the signal technology and to the industry at largest extent.

HVDC(High Voltage Direct Current) is an underwater cable between Jeju Island and Haenam in main land and supplies approximately 50% of electrical usage in Jeju Island. If there is any power failure due to HVDC, it will cost approximately 50,000 US dollars per day including Thermal Electrical Generation. Therefore it is absolutely necessary to recover the problem in rapid timely basis. In conclusion, jointing methode of HVDC cable is needed urgently to upgrade current HVDC underwater cable repair technique in Korea to minimize the cost and time factors.

The Bronchial stump disruption in bronchopleural fistula with empyema thoracis after pneumonectomy has remained one of the most dreaded complications of thoracic surgery. Management of chronic bronchopleural fistula still poses a therapeutic dilemma in spite of various surgical techniques that have been attempted to control this complication. Only recently, transsternal transpericardial approach for repair of the postpneumonectomy bronchopleural fistula has been utilized in some cases. The patient was a 31 year-old woman who was admitted to our hospital on August 18th, 1989 due to right postpneumonectomy bronchopleural fistula with empyema thoracis for 5 years since she had undergone right pneumonectomy due to pulmonary tuberculosis at E-hospital in 1984. Transsternal transpericardial closure of the fistula was employed and then the thoracic catheter was removed two months later, after the empyema cavity was sterilized by the Clagett method. So, we think this surgical technique is a relatively simple and effective method to the control of chronic postpneumonectomy bronchopleural fistula with empyema thoracis.

A 8-year-old, intact female, 2.1 kg, yorkshire terrier dog was referred to Animal Medical Center, Chonbuk National University due to right hindlimb lameness. Orthopedic examinations revealed pain during extension and flexion on stifle joint, positive cranial drawer sign, positive tibial compression test and patella luxation. Radiography showed the cranial displacement of right tibia with mildly increasing the synovial volume. The surgical procedure involved radial osteotomy of the proximal tibia and fixation by 1.2 T-locking plate. At two weeks after surgery, the patient was able to weight-bearing and gait gradually improved. This case report describes circular Tibial Tuberosity Advancement (cTTA) surgical technique and the successful surgical repair of cranial cruciate ligament rupture a dog.

In this paper three damaged exterior RC beam-column joints made of recycled aggregate concrete (RAC) were repaired. The aim of the study was to restore back the lost capacity of the beam-column joint to the original state or more. A relatively cheap material locally available galvanized steel welded wire mesh (GSWWM) of grid size 25 mm was used to confine the damaged region and then jacketed with cement mortar. Repaired specimens were also subjected to similar cyclic displacement as those of unrepaired specimens. Seismic parameters such as load carrying capacity, ductility, energy dissipation, stiffness degradation etc. were analyzed. Results show that repaired specimens exhibited better seismic performance and hence the adopted repairing strategies could be considered as satisfactory. These findings would be helpful to the field engineers to adopt a suitable rapid and cost efficient repairing technique for restoring the damaged frame structural joints for post earthquake usage.
