Background: Open surgical repair of abdominal aortic aneurysms was initiated by Dubost in 1952. Despite the rapid expansion of percutaneous endovascular repair, open surgical repair is still recognized for curative intent. We retrospectively analyzed surgical outcome, complications, and mortality-related factors for patients with abdominal aortic aneurysms over a 6 year period. Material and Method: We analyzed 18 patients who underwent surgery for abdominal aortic aneurysms between March 2002 and March 2008. The indications for surgery were rupture, a maximal aortic diameter >60 mm, medically intractable hypertension, or pain. Result: The mean age was $66.6{\pm}9.3$ years (range, $49\sim81$ years). Twelve patients (66.7%) were males a 6 patients were females. Extension of the aneurysm superior to the renal artery existed in 6 patients (33.3%), and extension to the iliac artery existed in 13 patients (72.2%). Five patients (27.8%) had ruptured aortic aneurysms. The mean maximal diameter of the aorta was $72.2{\pm}12.9$ mm (range, $58\sim109$ mm). Surgery was performed by a midline laparotomy, and 6 patients underwent emergency surgery. The mean total ischemic time from aorta clamping to revascularization was $82{\pm}42$ minutes (range, $35\sim180$ minutes). The mortality rate was 16.7%; the mortality rate for patients with ruptured aneurysms was 60%, and the mortality rate for patients with unruptured aneurysms was 0%. The postoperative complications included one each of renal failure, femoral artery and vein occlusion, and wound infection. The patients who were discharged had a long-term survival of $34{\pm}26$ months (range, $4\sim90$ months). Rupture and emergency surgery had a statistically significant mortality-related factor (p < 0.05). Conclusion: Emergency surgery for ruptured aortic aneurysms continues to have a high mortality, but unruptured cases are repaired with relative safety. Successfully operated patients had long-term survival. Even though endovascular aortic repair is the trend for abdominal aortic aneurysms, aggressive application should be determined with care. Experience and systemic support of each center is important in the treatment plan.

Patients with congenital heart diseases (CHD) are confronted with early- and late-onset complications, such as conduction disorders, arrhythmias, myocardial dysfunction, altered coronary flow, and ischemia, throughout their lifetime despite successful hemodynamic and/or anatomical correction. Rhythm disturbance is a well-known and increasingly frequent cause of morbidity and mortality in patients with CHD. Predisposing factors to rhythm disturbances include underlying cardiac defects, hemodynamic changes as part of the natural history, surgical repair and related scarring, and residual hemodynamic abnormalities. Acquired factors such as aging, hypertension, diabetes, obesity, and others may also contribute to arrhythmogenesis in CHD. The first step in evaluating arrhythmias in CHD is to understand the complex anatomy and to find predisposing factors and hemodynamic abnormalities. A practical stepwise approach can lead to diagnosis and prompt appropriate interventions. Electrophysiological assessment and management should be done with integrated care of the underlying heart defects and hemodynamic abnormalities. Catheter ablation and arrhythmia surgery have been increasingly applied, showing increasing success rates with technological advancement despite complicated arrhythmia circuits in complex anatomy and the difficulty of access. Correction of residual hemodynamic abnormalities may be critical in the treatment of arrhythmia in patients with CHD.

Objective: This study was conducted to confirm the effect of physiotherapy on the balance and walking in dog with sciatic nerve injury and degenerative arthritis of stifle joints. Design: Single case study Methods: The dog walked abnormally for six months and was administrated in S animal hospital. The dog's right hindlimb was operated for cranial cruciate ligament repair and the dog had been taking a nonsteroidal anti-inflammatory analgesic before being refered. There was severe degenerated osteoarthritis in the right hindlimb. During stance and walking, the right hindlimb was often shown partial weight bearing. The dog's left hindlimb was shown plantigrade stance and walking. The radiograph was shown an intact calcaneal tendon in the left hindlimb. In the neurologic examination, sciatic nerve injury in the left hindlimb was confirmed. The dog was treated using muscle strengthening, proprioceptive exercise, underwater treadmill and Laser therapy two, or three times a week for 3 months. At the 10th and 17th treatment, it was evaluated through stance and gait analyzer system to measure dog's balance and walking. Results: 3 months following physiotherapy, the dog's balance was improved in center of pressure(COP). And peak vertical force(PVF), vertical impulse(VI) was increased in right hindlimb and double stance was decreased. Conclusions: Physiotherapy may have improved the prognosis in this dog with severe osteoarthritis and sciatic nerve injury. This study suggested that animal physiotherapy is a valuable way to improve balance and walking.

The purpose of this study is to systematize the objectives and contents related to clothing education curriculum, and to research the needs for clothing education curriculum required y the Home Economics teachers working from elementary school to high school. These needs have been shown in the research by questionaires, which were distributed to the teachers in the Department of Home Economics School in Teajon and Ch‘ungch’ ongnam-do. The main results of obtained this study are as follows: First as the objectives of clothing education curriculum which are different from each school and each grade have not completely been systematizied they must be carefully reexamined and reorganizied in a coherent system. Second in the findings on the teacher's needs of clothing education curriculum the Home Economics teachers in elementary schools have basic knowledges and skills on clothing education. The teachers in middle schools have the knowledge of the selection care repair of cloths and also acquire skills for clothing education and consumption are some what difficult for elementary students to understand and the contents have been overlapped with those of middle schools curriculum they are not organized in a coherent system of clothing education curriculum higher than over and to systematize clothing education in a coherent and a unified way we must continue to study them and the needs for clothing education.

Advancements in bio-ceramic technology has revolutionised endodontic material science by enhancing the treatment outcome for patients. This class of dental materials conciliates excellent biocompatibility with high osseoconductivity that render them ideal for endodontic care. Few recently introduced bio-ceramic materials have shown considerable clinical success over their early generations in terms of good handling characteristics. Calcium enriched mixture (CEM) cement, Endosequence sealer, and root repair materials, Biodentine and BioAggregate are the new classes of bio-ceramic materials. The aim of this literature review is to present investigations regarding properties and applications of CEM cement in endodontics. A review of the existing literature was performed by using electronic and hand searching methods for CEM cement from January 2006 to December 2013. CEM cement has a different chemical composition from that of mineral trioxide aggregate (MTA) but has similar clinical applications. It combines the biocompatibility of MTA with more efficient characteristics, such as significantly shorter setting time, good handling characteristics, no staining of tooth and effective seal against bacterial leakage.

From 1983, until June, 1990, 10 patients with various type of truncus arteriosus underwent total surgical correction including Rastelli procedure at Seoul National University Hospital. The age at operation ranged from 1 month to 9 years [mean 2.1 years]. Six patients had truncus type I, 3 patients had truncus type II, and one patients had truncus type IIIc. Right ventricular pulmonary artery continuity was established with a porcine valved conduit in 6 patients, mechanical valved conduit in 1 patient, and bovine pericardial conduit in 3 patients. The postoperative right ventricular /left ventricular pressure ratio ranged from 0.4 to 0.71 [mean 0.51${\pm}$0.14]. The lung histology revealed grade II pulmonary obstructive disease even at 4 month of age. Five patients were dead in hospital [50%], and they were less than 2 year of age. One patient, who had severs congestive heart failure preoperatively, died of low output syndrome and the other died of low output syndrome with postoperative bleeding. There were three death, because of a pulmonary hypertensive crisis that might have been prevented. Two of the five survivors had conduit failure over a mean follow up of 42 months [range 1 to 78 months]. Obstructed conduit was removed and a new conduit constructed using the conduit bed as the posterior wall and the patch of bovine pericardium and Dacron as patch the roof of the conduit. One patient died of acute cardiac failure during the operation. Although results in infants less than 2 years old have not been good, current improvement of intra-and postoperative care suggested that prompt repair is indicated for infants with truncus arteriosus.

A 66-year-old male patient arrived at the emergency room with a crush injury to his chest. Multiple rib fractures, hemothorax on both sides, left scapular fracture, liver laceration, and retroperitoneal hematoma were found upon the radiologic examination. After closed thoracostomy, the patient had been initially admitted to the intensive care unit, but he was transferred to the general ward on the next day. On the 4th post-trauma day, the patient complained of severe pain and there was bloody drainage through the chest tube. This case is an exploration with the consideration of the possibility of major bleeding and the subsequent repair of the descending thoracic aorta. This case is regarded as a case in which the aorta wall was damaged as the sharp margin of the fractured ribs caused continuous irritation.

The management of defects in barracks facilities is carried out in such a way that defects found by the facility's manager are listed and requested to be repaired by the contractor. However, the standards and methods for the inspection of defects in the management of these defects are not specified in detail, so it is difficult to check the defects in detail. In response, the study first analyzed the current status of the number of defects that occurred in 2021 at official residences and barracks of certain units. As a result of the analysis, the number of defects that were not taken care of and that were not taken until the previous month was more than 10 cases on average per month. In order to reduce the number of such defects, major improvements in the field, timing, and safety inspection were found after the inspection of the military's facilities and safety, and the analysis of the manual of maintenance management. In addition, items for improvement of the checklist were derived through an analysis of the repair of defects caused by the unit's official residence and a total of 10 barracks facilities. Based on this, a checklist was proposed to manage defects in barracks facilities through interviews with military facility managers.

If multiple magnets are ingested, the potential exists for the magnets attracting one another across the gastrointestinal tract and inducing pressure necrosis, perforation, fistula formation, or intestinal obstruction. We report the case of a 12-year-old boy who suffered from a fistulous communication between the lesser curvature of the mid-body of the stomach and the duodenal bulb, caused by 4 ingested magnets (Singing Magnets, China). The patient presented with moderate mental retardation, a one-year history of cyclic vomiting, and abdominal discomfort. We present the findings of simple abdominal radiography, esophagogastroduodenoscopy, computed tomography, and upper gastrointestinal series. An emergency exploratory laparotomy was performed, which revealed a gastroduodenal fistula. Fistula repair and the removal of 4 magnetic toys were subsequently performed. We emphasize that clinicians who care for children should be aware of the hazards of magnetic toy ingestion.
