  • The purpose of this study is to present an in-site evaluation method for building insulation performance using Infra-red camera. The research contents of this study are to evaluate validity and suitability of building insulation defect survey using Infra-red camera for apartment housing with temperature & heat flow pattern analyze method. By establishing the in-site evaluation method building insulation performance using infra-red camera, it is expected that 1) building envelope repair market will be activated by using developed method in ESCO and remodeling companies, 2) the method developed in this research will contribute to reduce national energy consumption by promoting old building insulation remodeling.

  • Agenesis of the hemidiaphragm is unusual congenital anomaly associated with a high mortality. A case of congenital agenesis of left diaphragm was experienced in 22-day old male patient who was dyspneic and cyanotic on admission. Emergency exploration through the left eight interspace thoracotomy showed complete agenesis of the left diaphragm. The stomach and transverse colon covered with peritoneal sac was partially herniated into left hemithorax. The left lung was slightly hypoplastic. This neonate had no intestinal malrotation. The defect was reconstructed using Dacron graft. Dacron patch was sutured with interrupted Ethibond to chest wall anteriorly, esophagus aorta and costomediastinal sinus medially, and the tenth rib posterolaterally. Postoperatively, Extubation was performed at 1st day, but some respiratory difficulty was noted. Severe dyspnea was occurred at postoperative 11th day and so reintubation was done. Intermittently ventilatory support and intravenous alimentation were continued for 9 days after that. Thereafter he had no respiratory problems at discharge.

  • Cerebrospinal fluid (CSF) rhinorrhea usually occurs as a result of trauma including operation. Unheated CSF rhinorrhea may induce major morbidity such as meningitis and brain abscess, etc. This paper presents a review of four cases of traumatic CSF rhinorrhea Sites of CSF leakage were easily found out by intrathecal fluorescent dye injection. Surgery was performed by external ethmoidectomy approach and dural tear and bone defect was repaired with abdominal fat and free mucosal graft taken from amputated middle turbinates. We conclude that repair using free fat and mucosal graft via external ethmoidectomy approach could be accepted as the intial method of CSF rhinorrhea management.

  • Automatic junctional tachycardia is one of common atrial arrhythmia after open heart surgery which is often refractory to antiarrhythmic agents. We have experienced refractory automatic junctional tachycardia in two patients. In the first, it occured after cryosurgery for AV nodal reentry tachycardia and simultaneous dissection of a posterior septal bypass tract. In the second, it complicated the postoperative course of a patient who received intracardiac repair for double outlet right ventricle, ventricular septal defect, and pulmonary stenosis. Conventional therapy with atrial pacing, verapamil, digoxin, and electrical cardioversion were ineffective. Therefore, amiodarone was administered intravenously and it controlled automatic junctional tachycardia. The need for accurate and rapid diagnosis of this condition along with results of treatment are discussed.

  • Burn-in is an engineering method for screening out products containing reliability defects which would cause early failures in field operation. Previously, various burn-in models have been proposed mainly focused on the trade-off of shop repair cost and warranty cost ignoring manufacturing yield. From the view point of a manufacturer, however, burn-in decreases warranty cost at the expense of yield reduction. In this paper, we provide a general model quantifying a trade-off between product yield and reliability, in which any defect distribution from previous yield models can be used. A profit function is expressed in burn-in environments for determining an optimal burn-in time. Finally, the method is illustrated with gate oxide failures which is an important reliability concerns for VLSI CMOS circuits.

  • Protein modification by small ubiquitin-like modifier (SUMO) controls diverse cellular functions of protein targets including transcription factors and coregulators mainly in the nucleus and participates in maintaining cellular homeostasis. In addition, SUMO system plays important roles in DNA damage repair and maintaining genome integrity. Thus, in some cases, the loss of control on SUMOylation or deSUMOylation processes causes a defect in maintaining homeostasis and hence gives a cue to cancer development. Furthermore, recent study showed that SUMO system is also involved in cancer metastasis. In this review, we will summarize and discuss the possible role of SUMO system in cancer development and metastasis.

  • Authors carried out a retrospective study in 22 infants with Bochdaleck`s hernia who were operated upon, the results are; 1] the male to female ratio was 2:1 and the incidence of left side was threefold prevalent than right, 2] the chief complaint of those who were operated upon in neonatal period was dyspnea and diagnosis was possible by chest A-P, 3] primary repair was possible except one patient in whom a prosthesis was used. 4] complication occurred in 41% and pulmonary complication was most common including 5 pneumothorax, 5] mortality rate was 14%, the deaths occurred in infants who were operated upon within 48 hours of life and the lesion was left without sac, the defect was larger than average and all died within 72 hours after operation.

  • 지하철, 고속철도, 신공항, 공동구, 지하보도, 지하차도, 하수도, 도로 및 철도 등 의 지하구조에는 일반적으로 박스형태의 콘크리트 구조물이 건설되고 있다. 1990년 대 중반 이후 시공 및 사용중인 지하 박스 콘크리트 구조물의 균열 및 누수 등의 문제점이 사회적인 문제로 부각되기 시작하였다. 이러한 지하 박스 콘크리트 구조물에 발생할 수 있는 문제점은 크게 결함(defect), 손상(damage), 열화(deterioration)의 3가지로 구분될 수 있으며, 이들 원인은 구조물에 균열(cracking), 누수(leakage), 처짐(deflection), 부동침하(settlement) 재료분리(segregation) , 박리(delamination), 부식(corrosion), 박락(spalling)등의 현상으로 나타난다.(중략)
