One mid-esophageal carcinoma underwent esophagogastrectomy using an exclusive right thoracic approach entailing mobilization of the stomach through the esophageal hiatus. 62 year old male farmer was admitted with chief complaints of dysphagia and weight loss of 5 Kg. for 6 months, and regurgitation after soft meal for one week prior to this admission. Preoperative esophagogram revealed stricture with fungating mass at the level of the carina, which was diagnosed as squamous cell carcinoma at the time of esophagoscopic biopsy about 33 cm from incisor. Bronchoscopy revealed no invasive lesion or carinal fixation, and laboratory examinations were excellent for operative intervention. An exclusive right thoracic approach through right 5th rib bed was made for radical esophagectomy, mobilization of the stomach through the esophageal hiatus and primary esophagectomy. Postoperative recovery was uneventful except increased bronchial secretion due to senile emphysema, and follow up for 5 months after esophagectomy revealed good functioning esophagus with mild epigastric fullness after meal. Exclusive right thoracic approach for radical esophagectomy seems to be the procedure of choice in selected cases.

In order to know the comparative histological structure of the tongue of some domestic and laboratory animals, the root of the tongue has been investigated by light microscopy. The filiform papillae were mainly distributed in the root of the tongue of most animals and many foliate papillae were also found in the dog and rabbit. On the other hand, only filiform papillae were found in the fowl. The very well-developed mucosa was found in the cattle and in the dog, fowl, rat and mouse was fair. The lamina propria was well developed in the cattle, dog and pig, The muscle layer was well developed in the cattle. The adipose tissue which distributed between the muscle fibers was mainly found in the dog. The lingual glands were well developed in the pig, fowl and rabbit. The properties of these glands were shown strung acid mucopolysaccharide in the dog and pig, weak acid mucopolysaccharide in the fowl, rabbit and rat and neutral or acid mucopolysaccharide in the mouse. The species differences on the histological structure of the tongue were also ascertained by light microscopical observations.

Clinical observations were made on a total 104 cases of spontaneous pneumothorax during the period of 5 years from MAR. 1971 to MAR. 1976 at the Dept. of Chest Surgery, Korea University Medical College. The ratio of male to female cases was 7.4 : 1 in male predominance, and age distribution was 73% of the total cases within the 15-40 age range. There were 56 patients (53.8%) of right sided pneumothorax and 44 patients (42.3%) of left sided pneumothorax, 8 patients presented bilateral spontaneous pneumothorax. The etiologic factors were tuberculous origin in 42.3%, rupture of bullae or blebs in 15.4%, acute pulmonary infection in 3.8%, pulmonary paragonimiasis in 2.9%, cysticercosis 1%, Marfan's syndrome in 1.9%, unknown causes in 32.7%. In all 104 cases, closed chest tube thoracostomy were performed for reexpansion of collapsed lung. In 50 cases of 104 cases, intrapleural instillation of Quinacrine HCl (Atabrine, Winthrop Laboratories, New York, N.Y.) thru the chest tube was used to control of recurrent pneumothorax, and compared observation with 54 cases control group of closed chest tube thoracostomy only. In both groups, 1) cure rates were 63% in control group and 88% in Atabrine group. 2) average duration of inserted chest tube were 5.6 days in control group and 5.7 days in Atabrine group.

The first case was a 20 year old female who has been suffered from epigastric pain, and anorexia for 2 years. A thumb tip sized pulsion diverticulum 4cm above the esophagocardial junction was elicited by esophagogram and on exploration. A diverticulectomy with long esophagocardiomyotomy was performed. The second case was a 30 year old house wife who has had postprandial epigastric pain for 2 months accompained with frequent vomiting. Fiberscopy and esophagogram showed epiphrenic diverticulum of the esophagus. Same operative procedures were carried out and obtained a good result as first case. The third case was a 55 year old house wife who was admitted to this Chest Surgery Department because of regurgitation and intermittent vomiting for approximately 3 months. Esophagogram showed a large epiphrenic diverticulum of the esophagus. On exploration, a tennis ball sized pulsion diverticulum was found on the anterolateral wall of the esophagus. A partial esophagectomy including the diverticulum and esophagoesophagostomy was performed. The specimenshowed some erosive changes of the mucosal surface of the diverticulum and also the esophagus suggestive of diverticulitis and esophagitis. She has been satisfactory result until 4 months postoperatively, when she developed regurgitation and epigastric pain. Esophagogram showed stenosis of the operative site. Readmission and esophageal dilatations were done and improved without any problem. Epiphrenic or supradiaphragmatic diverticulum of the esophagus is a rare condition. Pathophysiologically, the conditions accompanied the spasm of the esophagus, many authors prefered the procedures of a diverticulectomy plus long esophagocardiomyotomy rather than simple diverticulectomy or esophagectomy and esophagoesophagostomy. Here we report the cases and reviewed the literatures.

During the period of 4 years from August 1, 1975 to August 1, 1979, authors have experienced 100 cases of multiple rib fractures by nonpenetrating injury at Department of Thoracic Surgery, Paik Foundation Hospital in Seoul, Korea. 1. The ratio of male to female patients with multiple rib fracture was 2.6:1 with male predominance and 84% of the total cases were between 20 and 50 years of age. 2. The most common cause of multiple rib fracture was traffic accident and falls accounted for the next largest group. 3. The most common site of rib fracture was 4th rib to 7th rib level on both hemithorax [52%]. 4. Associated injuries were cerebral contusion in 26%, clavicular fracture in 22%, long bone fracture in 22%, pelvic bone fracture in 10%, and scapular fracture in 8%. 5. Early complications and/or result of the multiple rib fractures were lung contusion in 23 cases, subcutaneous emphysema in 21 cases, hemothorax in 21 cases, hemopneumothorax in 6 cases, and flail chest in 12 cases. 6. The flail chests were managed by strapping the chest with adhesive plaster, external traction of flail segment with towel clip, ventilatory assistance for marginal clinical indications, and in cases of complicated with intrathoracic hemorrhage, wire fixation of flail segment through open thoraco-tomy. 7. The principles of therapy for hemothorax and/or pneumothorax were rapid reexpansion of the lungs by thoracentesis [11%] and closed thoracostomy [22%], but open thoracotomy had to be done on 3 cases because of massive bleeding or intrapleural hematoma and diaphragmatic rupture. 8. The over all mortality was 4% [4 among 100 cases] and the cause of all deaths was head injury.

가상화는 게스트라고 불리는 다중 가상 머신이 하나의 호스트 머신에서 동시적으로 수행할 수 있도록 하기위하여 물리적 자원을 다중 논리적 자원으로 추상화하는 기술이다. XEN에서 가상 하드 디스크를 지원하는 방법은 파일, 개별 파티션 및 실제 디스크와 같이 세 가지 방법이 있다. 가장 공통적으로 채택되는 방식은 하나의 디스크를 다중 파티션으로 나누고 각각의 파티션을 가상 하드디스크로서 각각의 가상 머신에 할당하는 파티션-기반 방식이다. 이러한 방식은 하드 디스크 기록 방식의 물리적 특성 때문에 내부 실린더 상에 위치한 파티션의 성능이 외부 실린더 상에 위치한 파티션의 성능보다 낮아져서 성능편차가 발생한다는 문제점을 지닌다. 또한, 서로 다른 가상 머신에서 요청된 I/O 요청들 간의 긴 탐색 거리를 필요로 하기 때문에, 동시에 다중 가상머신이 동작할 때 동시적 I/O 성능을 감소시키는 잠재적 문제점을 갖고 있다. 우리는 이와 같은 성능 불균형과 성능 감소를 극복하기 위해서 Onion과 Pizza로 불리는 새로운 두 가지 파티션 구조를 제안한다. 우리는 XEN 4.1에서 Domain-0 용도로 사용되어지는 Linux kernel 2.6.32를 수정함으로써 우리의 제안을 구현하였다. 성능평가 결과, Original의 파티션 구조와 비교 하였을 때, Pizza 구조는 가상 머신간의 공평성을 높이는 성능 결과를 보였으며 Onion 구조는 공평성을 개선했을 뿐만 아니라, 임의 또는 순차적 I/O에 관계없이 동시적 I/O 성능을 개선함을 파악할 수 있었다. Virtualization is a technology that abstracts physical resources into multiple logical resources so that multiple virtual machines, also called as guests, can run concurrently in a single host machine. In XEN, there are three different ways to support a virtual hard disk; file, individual partition, and real disks. The most commonly adopted way is the partition-based one, that divides a single disk into multiple partitions and assigns each partition into each virtual machine as a virtual hard disk. One problem of this approach is that the partition located on inner-cylinders gives a unfairly worse performance than the partition on outer-cylinders due to the physical characteristics of the hard disk recording mechanism. Also, it has a potential to degrade concurrent I/O performance when multiple virtual machines run concurrently due to a long seek distance between the I/O requests requested from different virtual machine. To overcome the unfairness and performance degradation, we propose two novel partitioning schemes, called Onion and Pizza. We have implemented our proposals in the XEN 4.1 by modifying the Linux kernel 2.6.32 which is used for the Domain-0. Performance evaluation results have shown that the Pizza scheme can enhance fairness among virtual machines while the Onion scheme can improve not only fairness but also performance regardless of random or sequential I/O, compared with the original partitioning scheme.

Due to the currently increased desire for improving the living environment of the residents in apartment buildings, some problems related to the noises from the indoor facilities & equipment have been raised and thus the requirements for improving the functions of such facilities & equipment and for reducing the noises from such ones are increasing. However, in case of the facilities & equipment, it is in the situation that such facilities & equipment are designed and established while the unique characteristics of the sound source and their effects on a unit house are not considered. Therefore, to predict the noisy situations in advance based on the noise characteristics of facilities & equipment and the types of rooms is a very important matter for reducing the noises from such facilities & equipment. In this study, the noise of the equipment, in order to understand the effect on the room, and using acoustic simulation. Flat-shaped, area, we tried to try to predict the noise reduction amount in the room due to the changes in the internal organs material. Kitchen hood noise through the field measurement of the apartment has to understand the impact on the living, We have applied the frequency another sound source characteristic value and terms and conditions to simulate. In kitchen hoods noise installed partition wall effects on the living room during the kitchen and living room, in the simulation after changing the sound absorbing material, to compare the results before and after change. We were compared with each other before and after partition-specific installation in the same plane. It was found that a considerable noise reduction effect from the plane after installing the partition wall.
