진딧물의 경보페로몬인 (E)-β-Farnesene의 합성과 생물활성시험
강석구,정경운,이정운,고현관 성균관대학교 기초과학연구소 1986 論文集 Vol.37 No.1
(E)-β-Farnesene, the alarm pheromone of aphids was synthesized from nerolidol by reacting in a sealed tube at 150℃ for 24h with DMSO. Base(KOtBu/DMSO) catalized elimination of HCl from farnesyl chloride at 50℃ for 4h afforded (E)-β-farnesene as the major product. Farnesyl chloride was prepared from nerolidol or farnesol with SOCl_2 or HCl. Biological activity test of (E)-β-farnesene thus synthesized was conducted.

Purpose: Most outcome studies of bypass surgery are limited to five years of follow-up. However, as human life expectancy has increased, analyses of more long-term outcomes are needed. The aim of this study is to evaluate 10-year outcomes of anatomical bypasses in aortoiliac occlusive disease. Methods: From 1996 to 2009, 92 patients (82 males and 10 females) underwent aortic anatomical bypasses to treat aortoiliac occlusive disease at Samsung Medical Center. The patients were reviewed retrospectively. Kaplan-Meier survival analyses were performed using PASW ver. 18.0 (IBM Co). Results: A total of 72 patients (78.3%) underwent aorto-femoral bypasses (uni- or bi-femoral), 15 patients (16.3%) underwent aorto-iliac bypasses (uni- or bi-iliac), and 5 patients (5.4%) underwent aorto-iliac and aorto-femoral bypasses. The overall primary patency rates of the 92 patients were 86.2% over 5 years and 77.6% over 10 years. The 10-year limb salvage rate and overall survival rate were 97.7% and 91.7%, respectively. Conclusion: The overall patency rates of bypass graft and limb salvage rates decreased as time passed. The analysis of results after bypass surgery to treat arterial occlusive disease will be needed to extend for 10 years of follow-up.
Development of Automatic Vibration System
Gwan-Hyung Kim,Oh-Hyun Kwon,Am-Suk Oh 한국정보통신학회 2015 2016 INTERNATIONAL CONFERENCE Vol.7 No.1
For the upgrading concentration and accuracy of the marksman, various types of disturbance are applied during firing exercise. Soldiers and policemen usually try to upgrade their shooting skill using periodic disturbance or aperiodic disturbance when they have firing exercises. In this paper, we will study and show the development of the automatic vibration system based on motion platform which can be used in firing exercise of police and military. The system is operating under the both different environments, i.e., periodic disturbance and aperiodic disturbance.
