Synthesis and Reactions of Benzimidazoline-2-thione Derivatives
이태룡,김경태,Lee Tae Ryong,Kim Kyongtae Korean Chemical Society 1989 Bulletin of the Korean Chemical Society Vol.10 No.1
Two properties of sodium naphthalenide (2), i.e. a strong base and a good electron donor were utilized for one pot synthesis: 2-alkylthiobenzimidazoles were synthesized in excellent yields from the reactions of benzimidazoline-2-thione (1) with an equimolar amount of alkyl halides in the presence of 2. Continuous addition of a different alkyl halide without the isolation of 2-alkylthiobenzimidazoles afforded 1-alkyl-2-alkylthiobenzimidazoles having different alkyl groups at N and S atoms in excellent yields. Further addition of 2 to 1-alkyl-2-alkylthiobenzimidazoles gave excellent yields of 1-alkylbenzimidazoline-2-thiones. When 2 in THF was added to a suspension of 1-alkyl-2-alkylthiobenzimidazoles in THF, a bond cleavage between N and C of alkyl group as well as S and C of alkyl group occurred. This is in contrast to the observation in which only cleavage between S and C of alkyl group takes place in the homogeneous solution.

Recently, the charbroiled beef Korean Restaurants have much more difficult problems than any other Food Service. Business the sale amounts reduced due to dull market and too many restaurants sprang up like so many mushrooms after a rain, including fluctuations of 0-15 and hydrophobic cow. So many restaurants were in serious financial difficulties. Moreover, Import liberalization of Beef cause rapidly increasing consumption of Import Beef in Korea. So the host will face the change to maintain their restaurants themselves. They gradually sold Import Beef disguised just as Korean Beef. The costumers believe what they are eating tastes different from Korean Beef. and finally the customers think that most restaurants use just Import Beef. Therefore, I'll study on how the manager will persuade the customers to eat beef in their restaurants, on how to distinguish Korean Beef from Import Beef, and on the different Eating-out. At last, I'll suggest that how to service the customers with excellent Korean Beef distinguished from Import Beef and how to plan the Marketing Strategy respond to the change in their circumstances.
초고속 대용량 바이오 기술과 이의 화장품연구 활용 방안
이태룡 ( Tae Ryong Lee ) 대한화장품학회 2001 대한화장품학회지 Vol.27 No.2
최근 인간 유전체 사업(Human Genome Project)의 완성과 DNA Microarray,Proteomics, Bioinformatics 등의 초고속, 대용량 처리 바이오기술(High Throughput Biotechnology) 의 발전과 함께 생명과학 분야의 연구는 획기적인 변화의 시기를 맞이하게 되었다. 이미 의약품 분야는 이러한 기술을 활용한 연구가 보편화 되어있고 선진 외국 회사들의 화장품연구 또한 이를 활용한 연구가 본격화 되고 있다. 화장품개발에 있어서도 이러한 기술들의 활용이 불가피하게 되었다. 여기서는 이러한 새로운 바이오기술들에 관해 간단히 알아보고 향후 이러한 기술들의 효과적인 화장품개발 관련연구 활용범위와 활용방법에 대하여 알아본다.
