The congenital esophageal atresia with tracheoesophageal fistula has been reported only 15 cases up to date in Korea, but this might be the first cases that was operated on successfully. A five day old male infant underwent the Haight`s operation on Nov-l,1968. The diagnosis was made by the esophagography and the operation was performed transpleurally through the right fifth intercostal space and the Stamm`s feeding gastrostomy was made on at the same time. The post-operative course has been uneventful until now. A literature review was done in this subject.

We have experienced 59 cases of videothoracoscopic operation for 7 months from January to August 1992 at Yongdong Severance Hospital, Yonsei University College of medicine. There were pneumothorax in 21 cases, mediastinal mass in 12 cases, diffuse intestitial lung disease in 7 cases, Buerger's disease in 1 case, metastatic lung cancer in 1 case and sclerosing hemangioma in 1 case. We had performed a variety of procedures (bullectomy in 21 cases, sympathectomy in 17 cases, mass excision in 12 cases, lung biopsy in 8 cases, lobectomy in 1 case). The patients were uneventful in post-operative courses.

This paper concerns the development of NC programming system TIG (Turning with Interactive Graphics) with interactive graphics for turning operation. The system cosists of the processor, the post-processor and the system-user interface. Different from previous segment contour based NC graphic programming systems, the frliability and efficiencyof programming is realized by using Boolean operation with block unit based ICONs for the geometry definition. The tool motion can be also displayed on the screen together with the part contour. The system calculate automatically the number of passes based on the user specified cutting conditions.

Price discount is one of the commonly used promotion strategies to increase sales and revenue. If a discount is perceived before the purchase (i.e., pre-purchase discount), consumers are likely to perceive it as a potential gain. If it is noticed after making a regular-priced purchase (i.e., post-purchase discount), consumers may develop negative emotions and attitudes. Based on the rising transparency and omnipresence of price and discount information through web and mobile platforms, we attempt to tackle an understudied topic on the negative effect of post-purchase price discount. Specifically, post-purchase discount information may increase consumers' perception of monetary loss, which may affect consumers' decision to return the product, potentially increasing the operating costs borne by retailers. Based on a close scrutinization of the current market environment and previous academic literature, we suggest a novel conceptual framework to understand consumers' perception, attitude, and behavior (perception of loss, willingness to return) upon perceiving various formats of discount promotion (absolute value vs. percentage discount) posterior to the purchase of a product. We also look at the effect of price level (low-priced vs. high-priced). For marketing practitioners, we intend to suggest optimal promotion formats that can alleviate consumers' negative perceptions and prevent additional operation costs.

Purpose: The purpose of this study was to examine and analyze the post operative fasting period of neonates in the intensive care unit (ICU) after receiving open heart surgery in order to provide optimal nutrition support for these neonates. The variables included biochemical nutrition indexes (albumin, total lymphocyte count, total cholesterol) and patient outcomes (duration of mechanical ventilation, ICU stay, hospital stay, infectious complication). Methods: The participants were 124 neonates in ICU after receiving open heart surgery, and the design of this study was to investigate their post operative fasting period retrospectively to analyze the biochemical nutrition indexes and patient outcomes according to post operative fasting period. Results: The results for 4 groups according to post operative fasting period showed that the group with less 48 hours of fasting had the best biochemical nutrition indexes and patient outcomes, followed by the 48-72 hour group, the 72-144 hour group, and the over 144 hour group. Conclusion: The results indicate that for new born babies receiving open heart surgery, the period of fasting after the operation should be minimized and tube feeding should be started as soon as possible.

But the study for treating them was rarely investigated. The purpose of this study was to report a case associated with treatment of the post-hysterectomy syndrome. Methods : A 52-year-old woman, who suffered from headache, dizziness, indigestion, lumbargo, insomnia, hyposthenia et al after total abdominal hysterectomy (TAH), was enrolled in this study. She received oriental treatments such as herbal medicine, acupuncture, moxibustion and dry cupping therapy for 8 days. Results : The symptoms after hysterectomy were markedly reduced by oriental treatments. Conclusion : The present study suggests that oriental treatments have a significant effect on the post-hysterectomy syndrome.

; A 15 years old girl was operated due to tuberculous paratracheal lymph node enlargement resulted in marked narrowing of lower part of trachea. She had suffered from sputum expectoration difficulty, which was developed dyspnea and cyanosis. 1st operation was simple removal of enlarged paratracheal lymph node through Rt. thoracotomy but restenosis sign developed 2 months later in spite of Anti-Tbc. medication. 2nd operation was resection of constricted tracheal portion [2.5cm] 8 end to end anastomosis under Extra Corporeal Circulation. Under Extra Corporeal Circulation trachea reconstruction offered many conveniences during operation.

Transposition of great arteries is relatively common cyanotic heart disease excluding TOF and is divided to two groups: complete TGA and congenitally corrected TGA. We experienced operations in 3 cases of TGA, the 1st case was 12 year-old male: TGA[SDD] + VSD+PS and treated with Rastelli`s operation, but expired due to low cardiac output syndrome postoperatively. The 2nd case,13 year-old male was also TGA[SDD]+VSD+PS and treated with Rastelli`s operation with good operative result. The 3rd case was 18-year old male: congenitally corrected TGA[SLL]+VSD+ PA+ASD and operation was done according to the met. hod reported by Danielson et al in 1980. Post-operative AV block led to implantation of permanent epicardial pacemaker with good result.

In ancient East Asia surgical methods existed even before the modern surgical methods were introduced. These surgical methods were mainly used to treat tumor, bruises, and dermatosis. The methods include many techniques such as making incisions in the skin, tell when to operate, and the aftercare following an operation. The traditional ways are not practiced any more due to its being replaced by the anesthesia techniques originating from the West, but the ancient methods can still be found in documents and these methods can be reproduced through such documents. There is a possibility that this ancient method could replace the present day method because of its nature-friendly characteristic as well as its post-operation management.
