살균전 통조림 내용물의 온도와 냉각처리 유무가 통조림의 살균에 미치는 영향을 조사하였다. 살균시간을 최소화하고 레토르트안과 통조림냉점의 두 곳에서 온도를 감지하여 치사율의 적산치를 계속적으로 이행할 수 있는 컴퓨터시스템을 이용하였다. 8% 벤토나이트 분산액을 301-5호관에 채우고 반복 실험을 통해서 내용물의 초온의 차이와 냉각수의 처리 유무 공히 살균시간에 뚜렷한 영향을 미쳤다. The effect of initial can temperatures and water cooling treatment on the cans for thermal sterilization was described. The accumulated lethal rate method based on microcomputer-based electronic system has introduced in this experiments to minimize the process time and provide precise temperature measurements at 2 points with continuous calculation of the lethal rate. According to a series of experiments which were performed by using 301-5 cans of 8% bentonite suspension, there was significant effect in accumulated lethal rate initiated in different temperatures and treated water cooling treatment.
國際化時代에 對應하는 日本農業 硏究와 새營農者敎育의 動向

海外旅行의 自由化에 따라서 各國의 相互交流가 빈번하게 되었다. '90年代 들어서는 國際化時代가 加速化 되고 있다. 우리와는 여러 가지 面에서 農業與件이 類似한 日本은 經濟大國이 된 餘力을 産業硏究와 새營農者敎育刷新에 경주하고 있다. 農業學術 硏究는 從來 獨自的으로 分散하여 實施해온 것을 聯合協力體制로 하여 地域農業의 總合的인 發展을 圖謀하는 統合體機構를 만들어 實施하고 있다. 즉 愛媛大學, 高知大學 및 香川大學이 平等한 立場에서 聯合하여 獨立硏究科로 開設한 博士課程의 生物資源生産學, 生物資源利用學, 生物資源保全學의 3個專攻을 들 수 있다. 農業試驗 硏究도 從來 各 分野別로 分散하여 實施해온 것을 近來에 와서 한데 모아 總合試驗으로 新說 整備하여 名實相符한 農業試驗 硏究의 中心이 되고 있다. 福岡縣 農業總合試驗場이나 態本縣 農業硏究센터가 그 보기가 되겠다. 새營農者敎育은 '70年代에 즈음하여 2年制短期大學(專門大學)水準으로 中央 1個校 各縣에 縣立 農業大學校를 設立하여 全員合宿으로 1年次는 敎養, 農業 基礎와 生産課題 敎育을 하고 2年次는 敎養, 農業基礎와 生産經營 課題敎育을 하여 地域産業發展의 中核 農業後繼者를 養成하고 있었다. 近來에 와서는 이들 農業者大學校가 縣의 農業硏究센와 한 構內에 있어 實體的인 敎育을 履修시키고 있었다. 農業硏究나 새營農者 敎育의 方向은 먼저 消費者자 원하는 良質의 農産物의 低廉한 原價로 生産하는데 모든 努力을 傾理하고 있었다. 즉 바이오 텍크技法의 畜産, 園藝 品種改善에 따른 優秀한 農産物을 省力化 農法으로 生産하고 있었다. 徹頭徹尾하게 실제교육을 長期間에 걸쳐 받아 해마다 輩出되는 2,100名이 後繼 農民이 되어 國際化 時代에 對應하는 日本農業을 계승하고 있었다. The Foundamental purpose of this study was to survey the current situation of agricultural research and new farmer's Education of Japan being equivalent to the international age in order to find out the improvement of Korean situation of them. Korea was very similar to Japan in every point of the developing processes of agriculture past 30 years. It is learned from this study that trends and changes of agricultural research and new farmer's education of Japan were as follows; 1) Local research stations and provincal colleges were unified to enable them to fulfil the top grade of reseaches in order to meet the rapid change of the agricultural technologies by the central government and the local government. 2) General developed countries had the short-term (less than one year) training program for new farmers, but Japan had two years' education program as a junior college level for new farmers. "Learning by doing" -courses of basic agriculture, schoolprojects of farm management, field practices of farm management in varrious developed farm houses were followed by the cooperative education among the farmer's training center, the provincial goverment and the local agricultural research stations.
A Statistical Theory of Conformational Properties of Amphiphile Molecules at the Air-Water Interface
Young Shang Pak,Hyungsuk Pak Korean Chemical Society 1991 Bulletin of the Korean Chemical Society Vol.12 No.2
A lattice mean field theory is developed to investigate the conformational properties of monolayer amphiphiles at the air-water interface. By generalizing Dill and Cantor's method and by extending Whittington's recurrence equation, we derive the supermatrix recurrence equation which is applied to calculation of various segment density profiles and order parameter, etc. In deriving the equation, we incorporated the chain stiffness effect and the chain connectivity which are distinguished features of linear chain molecule. Our result shows that, as the surface coverage $\sigma$ increases the chain ordering process with respect to vertical axis of the lattice system becomes dominant.
Computational Study of Human Calcitonin (hCT) Oligomer
Pak, Young-Shang,Shin, Jung-Ho,Jang, Soon-Min Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.12
We have performed long time REMD simulation on 15-19 residues of human calcitonin hormone (DFNKF) which is known to form highly ordered amyloid fibril. The simulation started from randomly oriented multiple DFNKF strand. Using all-atom level simulations with the generalized Born solvation (GB) model (param99MOD3), we observed spontaneous formation of ${\beta}$-sheet for tetramer. Interestingly, the current simulation gives anti-parallel sheet as a major conformation, consistent with experiments. The major interaction stabilizing the anti-parallel sheet seems to be the inter-strand hydrogen bond.

Endoscopic submucosal dissection has been a useful treatment of selected colorectal neoplasia cases. The incidence of perforation related to colorectal endoscopic submucosal dissection is 5-20%. However, while there have been numerous reports regarding retroperitoneal, mediastinal, pleural and subcutaneous emphysema after therapeutic colonoscopy, pneumoscrotum is a relatively rare manifestation of perforation associated with colorectal endoscopic submucosal dissection. In particular, pneumorrhachis, or air within the spinal cord, following therapeutic colonoscopy, is extremely rare. Herein, we report a conservatively treated perforation case as having pneumorrhachis, penumoscrotum, and pneumoperitoneum after colorectal endoscopic submucosal dissection.
