Esophagel atresia and tracheoesophageal fistula may occur as separate entities but usually occur in combination. First described by Durston in 1670, esophageal atresia was not successfully treated until 1939 when Ladd in Boston and Leven in St. Paul obtained the first survivors utilizing the methods of gastrostomy, esophagostomy and extrapleural ligation of the tracheoesophageal fistula as multiple operations which required months of hospitalization. Two years later Cameron Haight performed the first successful primary repair and afterward about 2000 cases of esophageal atresia with distal tracheoesophageal fistula reported in the world. In Korea, there appeared about 27 cases in the literature and 8 successful repaired cases noted in these year. Anther report two cases of esophageal atresia, of which one case was successfully treated with Haight`s method. Case 1.: Normal full term delivered boy with chief complaints of respiratory difficulty and persistent drooling with chocking, 3. lkg, was admitted with emergency 5 hours after delivery. Physical findings revealed no specific abnormal signs except distended abdomen and grunting respiration. Esophagograrn and bronchogram revealed proximal esophageal atresia and distal tracheoesophageal fistula proximal to the carina. Parent refused operative therapy and patient died 24 hours after discharge. Case 2. :3. lkg. normal full term delivered girl was admitted 4 days after delivery with chief complaints of regurgitation after feeding, chocking, cyanotic spell and fever since the day after delivery. Physical examination revealed persistent drooling, grunting respiration, and fever with moderate dehydration. Tracheoesophageal suction and fluid therapy with antibiotics improved her condition and subsided ]pneumonic condition. Esophagogram revealed markedly dilated proximal esophagus as blind loop and stomach distended with gas, and repairing operation as Haight`s method was performed on the 7th day after delivery. Patient tolerated all the operative procedure well and recovered uneventfully. Esophagogram on the 7th postoperative day showed passage of the lipiodol through the anastomotic side with moderate stricture,and feeding permitted. Patient tolerated all the feeding amount well and discharged on the 11th postoperative day. Followup revealed intermittent regurgitation after feeding and corrected with bougination.

To achieve high precision machine totals with high speed, it is needed to develop excellent rigidity statically, dynamically and thermally as well. In this view the chief things that thermal deformation of machine tool structure is directly related to high precision. And thermal behavior for transmission procedure have an effect on high precision. It is needed to exact temperature distribution of each members and all contact elements included for machine tool structure. This paper deals with thermal behavior caused by temperature variation in a high speed feeding process. At this procedure of temperature distribution is estimated using a Predictor-Corrector Method.

Since we have been discussing tile relationship of economizing at this paper. Value engineering (VE), as the term is generally understood, is concerned with reducing the cost of units or equipments which go into production. Until recently, our immediately problems of resources has been a short-term strategy. But due to the shortage of resources, our chief raw materials depend on the importation. In order to cope with such a present problems, first of all the policy of economizing resources by which the loss of materials can be minimized, and resources can be applied to more effectively, should be advanced to all things. Therefore, as the method of policy for the long tel.m for the sake of the use of resources, and as VE technical method can be assured in resonablity, it can be established of permanent organization (VE Team).

The chief factors for the penetration and diffusion of chloride ions in concrete are water-cement ratio(w/c), aging, thickness of cover concrete, chloride ions concentration of given environment, wet and dry conditions and etc. In this study, effect of w/c and aging on the characteristics of chloride ions diffusion in concrete were researched when environmental factors for the penetration and diffusion of chloride ions were constant. For this purpose, the voltages passing through the diffusion cell were measured by using accelerated test method using potential difference, and then diffusion coefficients of chloride ions by using Andrade's method were estimated for 44%, 49.5% and 55% of w/c, respectively. As a result, correlation among diffusion coefficients of chloride ions, w/c and aging were concluded through multiple regression model.

We have experienced 5 cases of Pectus excavatum corrected by Ravitch method without use of K-wire or metal bar from Jan. 1985 to Apr. 1986. All cases were male. The symmetric depression was in 4 cases, asymmetric one was in one case. The chief complaints were dyspnea on exertion, frequent U.R.I. and inferiority. The flail chest was developed in all cases, but it was insignificant in all cases except one who needed assist ventilation. Mediastinitis was developed in one case one week postoperatively but well managed with drainage. A distance from the posterior surface of sternum to the anterior surface of vertebral body was estimated preoperatively and postoperatively. Postoperative result was evaluated as the change of distance postoperatively. The change was 1.5cm minimally to 3.5cm maximally. Late results were "Excellent" in 3 cases and "Good" in 2 cases.uot; in 2 cases.

The goal of the present research was to develop a mean to determine indices of drought warning and emergency necessary to manage drought and establish water supply contingency plan for the municipal and industrial water supply system in urban areas. To do this, we worked on the Sayun catchment which is the main water source of Ulsan and used measured hydrologic data (storage, inflow, supply, outflow) from 1980 to 1996. The indices of drought calculated by the method of Phillips drought index based only on monthly precipitation do not pertinently represent drought phenomena in case water supply is from dam or reservoir in an urban area. Therefor, we developed the drought index technique including inflow, storage, outflow and supply which are the chief factors of drought management. The result showed that the method of Phillips drought index considering the capacity of water supply was excellent when applied to practical drought phenomena.

In order to study the immunohistochemical effects of Opae-san on gastric ulcer induced by HCl-aspirin in rats, experiments were done by oral administration and measure histological features of ulcer lesion, scaning electron microscopic appearance, the changes of numbers of parietal cells, chief cells, gastrin and somatostatin-immunoreactive cells. The obtained results are as follows: 1. Ulcerative lesions were numerously detected in control groups especially in junction of cardiac-fundic gastric mucosa and histologically very severe injury to gastric epithelium were observed too but in the Opae-san administrated groups, no gross lesion of ulcer were detected and histologically minor injury of gastric mucosa were observed. Most slight injuries to gastric mucosa were observed in 5 days after treatment. 2. The numbers of parietal cells were remarkably increased in control group but in Opae-san administrated groups appeared significant decrease compared to control groups. Most remarkably decrease of the numbers of parietal cells compared to control groups were observed in 5 days after treatment. 3. The numbers of chief cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably increase of the numbers of chief cells compared to control groups were observed in 5 days after treatment. 4. The numbers of gastrin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of gastrin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 5. The numbers of somatostatin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of somatostatin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 6. Scaning electron microscopically, severe denude and degeneration of gastric mucosa were observed in control groups but in Opae-san administrated groups the lesions were remarkably decreased compared to control groups.

Objectives : This study was planed to evaluate clinical status of the alopecia patients who had visited Korean medicine clinic. And the result from this study would provide a standard in Korean medical diagnostic and classification method of alopecia. Methods : Clinical records of 183 patients with alopecia seen from January 2004 to April 2005 at Korean medical clinic was examined. They were classified into 4 different types according to chief complains besides alopecia by 2 Korean medical doctors. Results and conclusions : We made clinical analysis of patients of alopecia from January 2004 to April 2005. Among the alopecia patients who visit Korean medical clinic, people age between 20 and 30 had high ratio. The duration from the recognition of initial hair loss to the time of the first visit to the Korean medical clinic was less than 12 months in 20.8%(38/138), and less than 60 months in 72.2% (132/183). The condition of alopecia was more worse than other alopecia patients who visit the west medical clinic. Also the ratio with increased temperature of face or scalp is chief complaint except alopecia in alopecia patients was high in men and the ratio with dysfunction of digestive system or chronic weakness was high in women. Among the incidence of alopecia, the androgenic alopecia was most in number; 43.7%(80/183) and the sex distribution showed 83 men and 100 women.
