  • Twelve patients had undergone repair of atrioventricular septal defects. Age at operation ranged from 2.4 years to 17 years[mean, 8.25 years]. Five patients were male and seven were female. Three patients had complete atrioventricular septal defect[Rastelli type A] associated with Down`s syndrome. One of the three patient with complete atrioventricular septal defect had tetralogy of Fallot. Three patients had the intermediate form and seven patients had the partial form. The primum atrial septal defect was closed with pericardial patch. The atrioventricular valve septal commissure[mitral cleft] was closed with pledgeted sutures. Three complete atrioventricular septal defect were undergone by two-patch technique. A crescent-shaped Dacron patch was used to occlude the ventricular septal defect. One patient of partial form was sudden death 5 days postoperatively. There were no another complications after surgery. One patient underwent reoperation for opened mitral cleft 2.5 years postoperatively. New York Heart Association functional class of patients was improved postoperatively.

  • This paper deals with the effectiveness analysis of an engineering system, which has two units of different strengths in parallel and one unit as a cold standby unit. Failure times for all the units have negative exponential distribution whereas their repair times have general distribution. Single server caters the need for the system. The effectiveness analysis of the system is done by using regenerative point technique. The different measures of effectiveness such as mean sojourn time, mean time to system failure, availability, busy period, etc, are derived. Cost factors also taken into consideration.

  • The objective of this study is to suggest DARE (Decision Alternative Ratio Evaluation) Method, which is usually using in VE(Value Engineering), as one of the evaluating alternatives techniques, especially deciding location. The process of solving location problem consists of 4 stages which are Data gathering and Confirming check list, Design of evaluating methodology, Evaluating, and Conclusion. In second stage which is the most important one among those, DARE method is adopted to solve location problem as a objective and scientific technique. The members who are participated workshop extremely agree to whole procedure of methodology and also their own conclusion through Workshop. This case study shows DARE method fits with select optimal location.

  • Tendoachilles rupture has recently seen an increase in frequency, accounting for up to 40% of all tendon ruptures. However, an acute segmental rupture of the Achilles tendon is very rare with only one case caused by predisposing factors, such as steroid injection. In this report, we highlight an unusual clinical presentation of a segmental rupture of the Achilles tendon without any underling predisposing factor and without direct trauma. Herein, we discuss its mechanism. Twelve months after surgical repair with open technique, this patient became fully functional again in daily activity.

  • The purpose of this study is clear the characteristic of the condition of conservation and rehabilitation by investigates of Modern Architecture (Cultural Properties 51, common architecture 93, total 144) in Kyoto-city. In registration system for conservation of Modern Architecture of Kyoto city, regulation is stricter than statute of country and various assistances of repair and so on are adopting more active incentive policy. The condition of ownership of Cultural Properties is almost corporation or foundation and individual ownership is dwindling. Various portion conservation ways (annex facade elements replica) are appearing by technique assistance means to keep the original form. It is increase that the conditions of rehabilitation are to commerce equipment or open to the public as like an exhibition hall. In case of renovate to commerce equipment, tendency as cultural-composition equipment is increasing as like a local community.

  • 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.

  • When the laryngeal web is small it rarely produces significant symptomatology. Large webs may produce stridor on both inspration and expiration, as well as hoarseness in various degrees. We have recently experienced with three cases of post-operative anterior glottic web after removal of the papilloma suffering from dyspnea and hoarseness. Layngeal webs with a definite voice problem or stridor should be managed surgically. And so, thyrotomy and a stainless steel keel insertion at the glottic level for repair of laryngeal web was performed. This technique has produced satisfactory result in all cases.

  • 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.
