Truamatic aortic rupture is usually fatal if left untreated. Prompt diagnosis is the cornerstone of suscessful management. But the usual screening tests are non specific and the accuracy of computerized tomography is low, Aortography which is a time consuming procedure may result in false-positive interpretations and significant morbidity. Recently transesophageal echocardiography provides a rapid, effective and relatively safe means of evaluating the distal aortic arch and also affords the opportunity to evaluate the heart during the same study, which may be of benefit in cases of suspected cardiac injury. The experience with the traumatic aortic ruptured patient and a critical review of the literature suggests that transesophageal echocardiography is a useful technique for the diagnosis of ruptured aorta following blunt chest trauma.

窒素水準이 배 품종一長十郎, 新高, 晩三吉 品種의 諸般生理現象에 미치는 影響

오중환 안성산업대학교 1983 論文集 Vol.15 No.-

1) N질의 시비량 增加에 따라 施肥量이 普肥區보다는 倍肥量區에서 收量增收 경향이 있었고 過肥區에서는 현저하게 增收性이 컸다. 2) N질의 시비량의 增加에 따라서 葉面積이 各 品種 共히 넓어졌다. 3) N질의 시비량에 따라 糖度는 過肥區가 普肥區나 倍肥區에 比하여 낮았음을 알 수 있었다. 4) Osmotic pressure를 species 별로 비교한 바 Nwlf 시비량이 증가함에 따라 삼투압이 증가하고 장십랑의 平均이 667.4인데 比하여 新高는 735.4였고 晩三吉은 732.2로 나타났다. 5) 內生的 Hormone의 Fructose와 Glucose 함량을 比較한 바 長十郞이 Fructose가 1.28mg이었고 Glucose가 17.12mg인데 比하여 新高와 晩三吉은 長十郞의 含量에 比하여 相當히 낮았다. 6) N施肥量에 따른 品種別 病葉數는 N施肥量이 증가 할수록 各品種 共히 증가되었고, 病葉數가 많았던 品種은 晩三吉이 가장 많았고 다음은 新高였고 아주 강한 耐病性의 品種은 長十郞 品種이었다. 7) 과수원 토양은 10cm와 20cm의 深層에서 채취하여 5요소를 分析한 바 20cm범위내에서 全窒素有機物, 燐酸, K가 많았고 Ca와 Mg는 表土에 가까운10cm 範位內에 含量이 많았다. 8) 窒素施肥量에 따른 品種別로 잎중의 질소함량을 N施肥量對時期別로 比較한 바 6월부터 8월말로 生育이 旺盛 할수록 N의 함량이 높았고 N施肥量이 증가됨에 따라 各 品種 共히 잎중 窒素의 농도가 높았다. 9) N시비량에 변화에 따라 인산의 葉中 농도를 6월부터 8월말에 걸쳐 조사한 바 成葉에 이름에 따라 品種 共히 P_2O_5의 量이 增加하였고 N過肥區의 P_2O_5의 量은 倍肥區에 比하여 葉中 함량이 낮았는데 이는 窒素와 燐酸間의 antagonism 現狀이라 생각 되었다. 10) N量의 倍加現狀에 따라 K_2O의 흡수량은 過肥區에서 잎중 함량이 감소 되었는데 이는 N : K의 拮抗作用 때문이라 推測 되었다. 11) N量의 倍加現狀에 따라 CaO와 Mgo의 일중 함량 변화는 成葉期에 이름에 따라 증가하는 경향이 顯著하고 過肥區에서 兩成分이 잎중 함량이 낮았는데 이는 N : Ca, N : Mg의 拮抗作用 때문이라 여겨진다. 1) Fallowing of the quantity of nitrogen, double nitrogen quantity fertilizer plot was increased yield comparison with normal nitrogen quantity, excessive nitrogen fertilizer plot was more increased yield than other treatment plot. 2) Leaves area were increased by increasing nitrogen fertilizer. 3) The quantity of nitrogen was increased, soluble solid (sugar content) was increased in normal nitrogen & double nitrogen fertilizer plot than excessive nitrogen fertilizer plot. 4) comparative with variety of osmotic pressure, the osmotic pressure was increased by increasing of nitrogen quantity, Singo's osmotic pressure was 735.4 & mansamgil variety osmotic pressure was 737.2 comparison with changsiprang's 667.4. 5) Comparative with quantitive of hormone of the fructose and Glucose, fructose of Changsiprang was 1.28mg, Glucose was 17.12mg but Singo and Mansamgil's glucose and fructose was more decreased than changsiprang. 6) Each variety of disease number of leaves were increased as increasing nitrogen quantitive fertilization, the most disease leaves was mansamgil variety than other varieties. 7) The analysis of ochard soil elements in depth from 10 to 20cm, total nitrogen organic matter P_2O_5 and K_2O were more encluded, Ca and Mg were more soil surface 10cm range area. 8) Each variety of nitrogen content in leaves by fertilizer were nitrogen quantitive fertilizer comparative with seasonal, nitrogen content was more higher by growth pear trees from June to the last of August. Fallowing of the nitrogen fertilizer increasing, each variety was more inculded nitrogen in leaves. 9) The observation of the P_2O_5 in leaves from June to August change the nitrogen fertilizer quantity, each variety was more inculded P_2O_5 as a old leaf, the double nitrogen fertilization plot's P_2O_5 element was lower in leaves than normal nitrogen fertilizer. It was think that between the nitrogen and phosphoric acid was antagonism. 10) As the phenomenon quantity of double nigrogen, observation a quantity of the K_2O was the lowest in leaf of excessive nitrogen plot. It was throught that there was antagonism between M:K fertilizer. 11) As the increasing the nitrogen fertilizer, the change of inculded of CaO and MgO were more increased in leaves as an old leaf, the excessive nitrogen plot was lower two elements in leaf. It was thought that there was antagonism in N:Ca, N:Mg.

오중환 안성산업대학교 1971 論文集 Vol.3 No.-

1. 各 殺蟲劑들이 葡萄晩腐病防除에 미치는 效果는 Tuzet, Difolatan>Bordeux,Daconil의 順으로 效果가 좋았다. 2. 現在 장려하고 있는 Daconil 30gr/18ℓ에 희석 살포하는 것은 만부병 방제효과를 나타내기에는 약한 것 같다. 3. Tuzet 과 Difolatan은 枝稍와 果實에 심한 약해가 유발되었다. 4. Dithane 과 Daconil 은 안심하고 사용할 수 있었다. To find out the most effective ones among the several fungicides being applicable to ripe rot in Grape growing, several fugicides were com compared each other and following results were obtained 1. The order of effectiveness was Tuzet ≒ Difolation > Bordeux ≒ Daconil. 2. It seems that the current recommended 30 gr of Daconil per 18ℓ or water is too weak to be effective to the ripe rot. 3. Tuzet and Difolation have induced the chemical damaged on branches, shoots and fruits of grapes.

Gunshot injuries to the heart, lung and great vessels are rare, but gunshot injuries are increasing with increased use of guns in hunting. We experienced a patient whose heart had been injured in a hunting accident and report with literature reviews. A 43-year-old man was admitted to our hospital with gunshot wounds to the scalp, face, upper extremity, and anterior chest. Computed tomography and echocardiography revealed several pellets in the chest wall, epicardium, and myocardium of the right ventricle. The pellets in the chest wall and epicardium were removed by a left thoracotomy, but the pellet in the myocardium of the right ventricle was not removed. The patient was discharged from the hospital without any significant residual complications and has been followed up for 9 months after discharge.

배나무잎 검은점병의 발생원인 조사

오중환 안성산업대학교 1996 論文集 Vol.28 No.-

Symptom development of pear abnormal leaf spot was highest at the day/night temperature regimes of 23/18℃, and reduced remarkably at the higher and lower temperature regimes as 28/23℃ and 18/13℃. When the pear leaves were bagged or wrapped with various covering materials, little or no symptoms were developed. This was considered to be due to the masking effect of the symptom development induced by high temperatures as up to 46.8℃ after leaf covering. Chemical properties of soil samples from diseased and healthy trees did not show a consisent trend except phosphate whose content was higher in the soil from diseased trees. Simptom development was delayed when moisture levels in soil was over on below the optimum conditron, although the final disease severity did not differ greatly.

배나무잎 이상반점 증상의 접목전염에 관한 연구

오중환 안성산업대학교 1995 論文集 Vol.27 No.-

배나무잎 이상반점 증상의 접목전염 여부를 온실과 포장에서 여러가지 접목방법으로 시험 하였다. 이병가지와 건전가지를 2월에 채취하여 건전한 실생대목에 접목한 결과 이병가지를 접목한 가지에서만 발병되었다. 또한 이병가지와 건전가지를 각각 첫 번째 접수와 두번째 접수로 하여 건전한 실생대목에 접목했을때도 예외 없이 두번째 접수에서의 발병이 확인되었다. 이병주와 건전주를 기부에 설접(舌接)하여도 두주 모두 발병하였다. 지표식물 HN-39를 두번째 접수로 이용하고 첫번째 접수를 이병가지로하여 배나무 실생대목에 접목하면 HN-39에서 심하게 발병하였다. 농업과학기술원 과수원에서 건전주에 이병가지를 고접하면 고접한 당년에는 접수에서만 발병되었고 다음 해에는 고접한 주지에, 3년차에는 배나무 전체가 심하게 발병되었다. 이상의 결과로 볼 때 배나무 이상반점증상은 병원이 접목전염하는 것으로 생각된다. Nature of graft transmissibility of pear necrotic leaf spot disease was examined by various grafting methods in the greenhouse and field. When the diseased and symptomless twigs were collected in winter and grafted in the next spring to the seed-originated healthy root stock, the abnormal leaf spot was developed only in the case of the diseased twigs. Double grafting on a seed-originated healthy root stock, where the diseased and the symptomless twigs were used as 1st and 2nd scion, respectively, developed necrotic leaf spot lesions without exception on the 2nd scion. Tongue-graft with the diseased and the symptomless trees also incited abnormal leaf spots on the both trees. Necrotic leaf spots were also developed on HN-39, an indicator pear tree, used as a 2nd scion in a double graft test, where the diseased twig and a seed-originated healthy tree were used ad the 1st scion and the root stock, respectively. when the diseased twig was top-grafted to the healthy root stock, lesion developtment of necrotic spot was limited to the grafted twig itself in the 1st yea, but expanded to the main branches in the 2nd year, and spread over the whole tree in the 3rd year. This result indicates that the causal agent of necrotic leaf spot disease is transmitted by graft.
