부분 심낭결손, 장기역위증을 동반한 기관지 낭종

고재웅 대한흉부심장혈관외과학회 1987 Journal of Chest Surgery (J Chest Surg) Vol.20 No.2

We recently experienced a case of bronchogenic cyst associated with situs inversus and partial pericardial defect. The patient was 26-day-old-male who showed severe respiratory difficulty. Left upper lobectomy and direct suture of partial pericardial defect were undergone successfully, but his postoperative course was unfortunate because of respiratory insufficiency.

With the advent of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. Rupture of the bronchus is an unusual result of nonpenetrating trauma to the chest. This case was a 30 years old male who was a worker in the mine. The patient had sustained a compression chest injury with multiple rib fracture. At the time trauma, he was suffered from dyspnea, hemoptysis and hemopnemothorax of both side were noted. After tracheostomy, corrective surgery was performed with end-to-end anastomosis on the 8th time after trauma. Postoperative course was uneventful and good result of bronchogram with hypaque on the 16th day after operation.

Nano-sized spherical MgB2 powders were synthesized by spray pyrolysis method. The influence of solution concentration and furnace reaction temperature on morphology and average particle size were investigated. For adequate preparation conditions, it has mostly spherical, solid and narrow particle size distribution. Average particle size(X50) distribution was below 100 nm. The critical temperature for the synthesized MgB2 was around 36K.

원로초대석-내 젊은 길목에서

고재웅,Go, Jae-Ung 한국하천협회 2006 하천과 문화 Vol.2 No.4

하천에서의 흐름은 상류(常流)흐름으로 대표된다. 곳에 따라 수로경사가 급한 곳에서 국부적으로 사류(射流)가 생기지만 홍수흐름이 아니고는 보기 힘든다. 하천을 좋아하면서 그리고 전공하면서 현장에서 부딪치는 홍수의 사류흐름은 다스리면서 극복해 나가야하는 대상이이기에 이에 따른 어려움이 적게 나타나기를 늘 바라면서 살아왔다.

流砂의 始動에 관한 實驗的 硏究

The initiation of sediment transport is determined from an "average Shields curve" at the present. A Considerable amount of scatter of experimental points in average Shields curve by many authors is mainly due to the inconsistency in the determining of the critical stage, and the fact that the experimental results corresponding to granular materials possessing different geometric properties are plotted on the same system of coordinates. In this paper experimental runs for twenty different size distibutions of sand bed materials were performed in 12m long and 0.5m wide channel and slope adjustable. The bed materials used in the experiements were natural river sand. The mixture of the grain size range from 0.019 mm to 6.0 mm. Five family of the dimensionless grain size distribution curves are represents the twenty different size distributions. The study results show the fairly well agreement with Yalin's suggestion. In this paper five family of Shields curve has been established where each individual curve would represent a particular geometry of granular material. Then the critical tractive force was correlated with the median size of the granular bed materials. The relationship is concluded as follows; ?? = 0.009 ??

Purpose: To report cases of corneal perforation among corneas treated with cyanoacrylate tissue adhesive. Methods: We performed cyanoacrylate tissue adhesive application on 1 case of corneal perforation due to fungal keratitis, one case of corneal perforation due to neurotrophic keratitis, one case of corneal fistula due to foreign body and one case of corneal perforation due to corneal stromal dystrophy. After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation was conducted in two cases, and keratoplaty was performed in another two cases. Results: Postoperative follow-up period was 12 months on average. In all four cases, ocular integrity was successfully restored. There was no sign of recurrence, infection or inflammation. Conclusions: Cyanoacrylate tissue adhesive monotherpy can restore ocular integrity successfully in various type of corneal perforation and After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation and keratoplaty can be performed additionally.

The study was carried out to investigate the effects of dietary carotenids and β-carotene on the hematological changes caused by alcohol administration into the rats. The results were analyzed using several statistical methods; SPSS computer program for measuring the mean values and standard deviations, one way ANOVA for the test of significance, Duncan method for post HOC multiple comparison, and Pearson method for measuring the correlation coefficient. The following are the conclusion from those statistical analysis. 1. ALB and TB were shown to have the most significant correlation among the blood compositions f개m the basic dietary groups. 2. BUN and CHO were shown to have the most positive correlation among those from the carrot-fed groups. 3. CA and AG were shown positively correlated, and CHO and IP negatively correlated, respectively among those from the cheese-fed groups. 4. AP was shown positively correlated among those from the alcohol-administrated groups. 5. CHO, CA and BUN were shown positively correlated, and CA was negatively correlated among those from the β-Carotene -fed groups. 6. TB and TP were not affected by the correlations between the blood composition from all the experimental groups.

A clinical study was performed on 363 cases of pulmonary tuberculosis treated surgically resection during the period of 3 years from January, 1986 to December, 1988 in the National Kong-Ju Hospital. The results obtained are follows: 1. The ratio of male to female was 1.6:1 in male predominance, age from 20 to 40 occurred 82.6% of the total cases. 2. The moderately advanced cases was the highest incidence with 53.2 % for extent of disease, duration of illness which 1 to 5 years before operation was 40.8 % of the total cases. 3. Preoperative sputum examination for AFB was 53.2 % in negative but in spite of chemotherapy, persistent positive sputum was 46.7%. 4. Indication for surgery were: total destroyed lung was 35.5 %, destroyed lobe or segment with or without cavity was 30.6%, empyema with or without bronchopleural fistula was 8.5%, according to type and site of surgical procedure, pleuropneumonectomy and pneumonectomy was the highest incidence with 53.4 %, left site was slightly more than right with 55.9 % of the total cases. 5. The incidence of postoperative complication was 10.2 % and then the highest incidence was empyema with or without bronchopleural fistula with 4%, according to type of surgical procedure, postpleuropneumonectomy and postpneumonectomy was 6.1 % of the total cases. 6. Postoperative mortality was 1.4 % of the total cases, according to cause of deaths, hypovolemic shock due to bleeding were 2 cases, respiratory failure were 2 cases and hepatic coma due to hepatic failure was 1 case.
