Ebstein`s anomaly is a rare congenital cardiac malformation and characterized by downward displacement of an abnormal tricuspid valve cusps. But until now, the ideal surgical correction is still controversial. We present a case of Ebstein`s anomaly experienced lately. The patient was 13 year old girl with the complaints of dyspnea on exertion, fatigability and cyanosis. Echocardiography revealed downward displacement of septal leaflet of tricuspid valve and atrialized right ventricle. Cardiac catheterization and cineangiography revealed ASD and large right atrium. During operation, the atrialized right ventricle was plicated and tricuspid annuloplasty was done. And the two secundum type ASD`s were closed by direct suture closure. The patient`s postoperative course was uneventful and discharged on the 24th postoperative days.

Pulmonary sequestration is an uncommon congenital malformation characterized by the presence of non-functioning lung tissues which receives its blood supply from an anomalous systemic artery instead of a pulmonary arterial branch. We present a case of intralobar pulmonary sequestration experienced lately. The patient was 7 years old girl with the complaints of chronic productive cough and right lower chest pain. Serial chest films showed a large cyst with or without a air-fluid level on the right lower lung field. Aortography revealed an aberrant artery originating from thoracic aorta just above the diaphragm and that drained into the right inferior pulmonary vein. During operation, a large abscess cavity measuring 6.5x5x5 cm in dimension at the right lower lobe was noted. And the two aberrant arteries, measuring 3 mm in diameter, arising from thoracic aorta 5 cm above the diaphragm was noted. After division and ligation of the aberrant arteries, right lower lobectomy was performed and the patient`s postoperative course was uneventful.

Mesothelioma is a primary tumor of the pleura. There are two forms of mesotheliomas; diffuse form and localized form. The majority of localized mesotheliomas are benign, but the tumor with pedicle recur at 20% after removal of it. Malignant localized fibrous mesothelioma is differential diagnosed pathologically and clinically with diffuse mesothelioma. Symptoms of localized mesothelioma are generally related to the size of the tumor. We presented one case of malignant localized fibrous mesothelioma. The patient was 32 years old female and chief complaints were dyspnea and dry cough. Sputum cytology and needle lung biopsy were not able to diagnose definitely the tumor. Explothoracotomy was carried out for definite tissue biopsy. At the time of operation, huge adult head size mass was in the right thoracic cavity. The surface of the mass was nodular, multilobular and had hard consistency. Pedicle was formed above first rib and its diameter was 4.5cm. There was no adhesion except to RUL. Frozen biopsy suggested mesothelioma. Extirpation of the mass, right upper lobectomy. and partial pleurectomy were carried out.

A surgical operation on a patient with infected left atrial myxoma is presented. The patient was a 50-year-old woman who was admitted to the Kyung Hee Medical Center Hospital on March 7 1987 with complaints of high fever, cough and dyspnea that occurred a few days prior to admission. She, who no definite history of the previous cardiac-related problems was obtained from, had visited a dentist to have her eight teeth pulled out a few months prior to this admission. A preoperative 2-D echocardiogram revealed a left atrial tumor, strongly suggesting myxoma and two blood cultures drawn prior to surgery yielded streptococcus viridans. Under the preoperative impression of an infected left atrial myxoma, the tumor was removed through a biatrial approach after establishing CPB and cold cardioplegic. Pathologic examination of the tumor demonstrated a typical myxoma with bacterial colonies within. Postoperative course was uneventful and she was completely well at discharge from the hospital. To our best knowledge, this report is the first surgical experience of infected left atrial myxoma in the Korean literature.

Den have been many construction projects in urban n We have a lot of problems which have to be solved especially against residence complaints existing building damage due to construction worts. We sometimes have to pay a certain amount of cost to solve the above problem, not in planning. In addition to, we have to suffer from work delay due to confronting problem. Almost all of these are due to blasting work to break solid rock to be excavated. Therefore, this study is focused on finding out how to reduce noise more cheaply. Four cases(4) as cheaper but more effective way have been tested to find out which way of local fence will have better moise reduce function in a field site. Where five(5) large breakers are being operated. It is concluded that more form and shape of local movable panel than the site of panel can be influenced on noise reduce.

The Caustious blasting have often increased Complaints of ground Vibration and Sound when the Wire-Tunnel Constructed in Pusan. In order to prevent the influence to housing structure, it was necessary to predict blasting-Induced Vibration and Sound. The Suveyer determined the Burden and spacing of Drill holes, minimum delay charges within a allowable Vibration and Sound Level. Tunnel drilling and Ignition patterns are made as follows; No. 1 Tunel (Stable rock, hard rock) No.2 Tunnel (Instable plastic rock; wethered rock) and other Tunnels (Instable rock). The result of 1st testing blasting of No. 1 Tunnel was recorded Under allowable Vibration Level but sound was over 75 Db of allowable value. So Tunnel drilling pattern was amended with 52 Non-charg holes to reduce the blast-sound. The other pattern had no need to amend.

This paper presents on the structural behavior of the the methyl methacrylate monomer (MMA) double wide flanged the glass fiber-reinforced polymer(GFRP) pipe composite structures for the manhole raise. The evaluation of structural performance on this composite structure was conducted by the axial load, fatigue load, and ultimate load test. The assessment indicates that the MMA double wide flanged GFRP pipe composite structures was confirmed safety, durability and reliability in result as expected. It was found that this composite structure was able to short working times to around 30-50% and construction costs to around 10-23% with compare other construction methods. Also, environmental pollution and civil complaints will be prevented because there will be no longer any noises, vibrations, dust, or construction wastes.

This study has been peformed to investigate storage space types of old-fashioned traditional dwelling units where older couples maintain their traditional farming lives. In this study it is observed that residents of the traditional farm-houses are exposed to higher level of environmental and emotional pressures. However it is also observed that the older residents are generally manifesting a consistent subculture of the old-timers without noticeable complaints. The usage and morphology of storage spaces are as follows: (1) Storage space in the ceiling are under control of old couple and used for seasonally varied farm products and household equipment. (3) All the households use longterm storage space under wooden floor; the hidden ground is used for keeping miscellaneous tools and fermented foods for years. Overall in this stud it is observed that traditional farm houses are well modified for physically and emotionally frail elderly residents.
