朴基泰 충주대학교 1990 한국교통대학교 논문집 Vol.24 No.-
A Study for the Efficency preperation of ?? When stanless steel electrode as cathode and graphite rode electrode as an anode were set up in silver nitrate solution of 300㎖ beaker and the electrolysis was performed. I found that the most efficiency deposited ?? at anode had following conditions. 1. Concentration of the electrolyte is 1.0M AgNO₃ 2. Intencity of the current is 300mA. 3. Distance between two electrode is 5cm. 4. Width of the anode is 1.5cm 5. The economic electrolysis time is about 100 minutes. 6. When the equipment has to be set up crystal combined, not the crystal, it is made larger and the efficiency become higher.

초미세 위치결정시스템을 이용한 실리콘 웨이퍼의 파괴거동에 관한 연구
박기태,이병룡,박규열,홍동표 韓國工作機械學會 2000 한국생산제조학회지 Vol.9 No.1
The background of this study lies in the investigation of the formation mechanism of ductile mode(nanometer-size) chips of bristle materials such as fine ceramics, glass and silicon. As the first step to achieve this purpose, this paper intends to observe the micro-deformation behavior of these materials in sub ㎛ depth indentation tests using a diamond indentor. In this study, it was developed Ultra-Micro Indentation Device using the PZT actuator. Experimentally, by using the Ultra-Micro Indentation device, the micro fracture behavior of the silicon wafer was investigated. It was possible that ductile-brittle transition point in ultimate surface of brittle material can be detected by adding an acoustic emission sensor system to the 'Ultra-Micro Indentation apparatus.

金屬 酸化物에 의한 Benzylamine類의 酸化 反應에 關한 硏究
朴基泰 忠州大學校 1995 한국교통대학교 논문집 Vol.30 No.2
Selection properties of metallic oxidizing agent such as NiO₂and Ag7O8NO₃were investigated through oxidations of benzylamine and its 6ring-substituted derivatives. It was observed that benzonitriles and benzaldehydes were main products in oxidations of benzylamines, and the ratio of these two products varied with each oxidizing agent. The selective property of each of these oxidizing agents was investigated by checking the ratio of yields of two main oxidation products, benzonitriles and benzaldehydes. In Ag7O8NO₃Oxidations, a substituent effect was observed. That, the ratio of benzaldehydes was increased by electrondonating groups while the ratio of benzonitriles was increased by electron-withdrawing groups.

工業專門大學 敎育의 效率을 높이기 爲한 硏究 : 食品工業科를 中心으로 mainly on the Department of Food Engineering
朴基泰 忠州大學校 1982 한국교통대학교 논문집 Vol.15 No.1
This study was undertaken to investigate various problems on the effective education of students who are taking up Food Engineering Technical Junior College. The results obtained from the questionnaires of 132 students are as follows: For the purpose taking up the course of food Engineering in college, it is more desirable to admit the students who have mastered general Chemistry of high school level. The system for the entrance examination should be reformed for the effective education at the Technical Junior College.

金屬酸化物에 依한 Benzylamine의 酸化反應에 關한 硏究
朴基泰 忠州大學校 1991 한국교통대학교 논문집 Vol.25 No.-
The amount of available oxygen contained in Ag??O??NO?? is 2.94 x 10??g atomic oxygen/g Ag??O??NO?? which is similar to NiO??. When Benzylamine is oxidized by other metallic oxides, the mixture of Benzaldehyde and Benzonitrile or Benzaldehyde is formed. But, when Benzylamine is oxidized by Ag??O??NO??, 100persent Benzonitrile is formed. Therefor, it is proved that Ag??O??NO?? is an appropriate oxidizing agent which can produce pure Benzonitrile.

金屈酸化物에 依한 Benzylamine류의 酸化反應에 關한 硏究
朴基泰 忠州大學校 1994 한국교통대학교 논문집 Vol.29 No.2
Selective properties of metallic oxidizing agents such as NiO₂ and AgO were investigated through oxidations of benzylamine and its 6ring-substituted derivatives. It was observed that benzonitriles and benzaldehydes were main products in oxidations of benzylamines, and the ratio of these two products varied with each oxidizing agent. the selective property of each og these oxidizing agents was investigated by checking the ratio of yields of two main oxidation products, benzonitriles and benzaldehydes. In AgO oxidations, a substituent effect was observed. That is, the ratio of benzaldehydes was increased by electrondonating groups while the ratio of benzonitriles was increased by electron-withdrawing groups.

Ag O NO₃-H₃PO₄에 의한 Benzylamine류의 산화 반응에 관한 연구
朴基泰 忠州大學校 1996 한국교통대학교 논문집 Vol.31 No.2
Benzylamine and its bring-substituted derivatives were used to study selective properties of metallic oxidizing agent Ag??O??NO₃, through oxidation. It was observed that benzonitriles and benzaldehydes were dominant products in oxidations of benzylamines, and the ration of these two products varied with each oxidizing agent. By investigation of the ration of yields of tax main oxidation products, benzonitriles and benzaldehydes, the selective property of each of these oxidizing agent was studied. In Ag??O??NO₃-benzene oxidation, a substituent effect was observed that, the ratio of benzalhyde was increased by electron-donating groups while the ratio of benzonitriles was increased by electron-withdrawing groups. The substituent effect was also observed and the intensity of substituent effect was more increased when Ag??O??NO₃-H₃PO₄was used as oxidizing agent.
