오프라인 프로그래밍을 이용한 SCARA 로봇의 통합 제어 시스템 설계
정경규,장영희,차보남,한성현,이만형 한국공작기계학회 2001 한국공작기계학회 춘계학술대회논문집 Vol.2001 No.-
We developed a Off-Line Graphic Simulator which can simulate a robot model in 3D graphics space in Windows 95 version. 4 axes SCARA robot was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D graphics.

Ethyl acetoacetate was prepared by the condensaiton of Ethyl acetate using phase transfer catalyst. In this study the writer investigated catalyst activity of such quaternary ammonium salts as Benzyl-triethylammonium chloride (BTEAC), Benzyltrimethylammonium chloride (BTMAC Tetra-n-butylammonium bisulfate (TBAB) and Trioctylmethylammonium chloride (TOMAC). Among these salts, BTEAC and TBAB catalyze the condensation of Ethyl acetate, and the percent yield of Ethyl acetoacetate is roughly proportional to the moles of catalyst added.
몇 가지 4차암모늄염의 상간이동촉매반응 (Ⅱ) : 아닐린의 슬픈화반응

Phase Transfer Catalysis of organic phase soluble Quaternary ammonium salts such as Tetra-n-butylamm-onium bisulfate (TBAB), Benzyltriethylammonium chloride (BTEAC), Benzyltrimethylammonium chloride (BTMAC) and Benzyldimethyltetradecylammonium chloride (Zephiramine), in the sulfonation of Aniline was attempted. Among the these salts, TBAB, BTEAC and BTMAC catalyze the sulfonation of Aniline. The reaction was strongly catalyzed by TBAB and BTEAC.
p-Chlorotohiene으로 부터 p-Toluic acid의 합성
정경규 釜山大學校 師範大學 1975 교사교육연구 Vol.2 No.2
p-Toluic acid was synthesized by the Grignard synthesis with p-Chlorotoluene and activated magnesium metal. The activated magnesium metal was prepared by reduction of anhydrous magnesium chloride with some alkali metals in various ethers. The addition of potassium iodide and some other metal halides to reaction mixture has produced a highly reactive magnesium metal and p-Toluic acid in high yields.
