기업특성과 물류정보기술 활용간의 관계에 관한 실증적 연구 : 구미 지역 제조업을 중심으로
이시호 한국정보시스템학회 1996 情報시스템硏究 Vol.5 No.1
The role of Logistics Information Technology(LIT) activity within the firm has broadened considerably over the past decade and it been a topic of growing importance for both practitioners and academicians since the mid-1990's as logistics efficiencies have become a main concern in today's business management. This research empirically examines the difference between firm characteristics and LIT activity, thus it offers an strategic guideline for practicers.
Sodium Starch Sulfate의 합성과 그의 응용(I)
이시호,고석원 한국섬유공학회 1983 한국섬유공학회지 Vol.20 No.4
Starch sulfate was synthesized as sodium salt by reacting DMF-So$_3$complex with starch nitrite which had been obtained by substituting the hydroxyl groups of starch to nitrite groups by treating starch with dinitrogen tetroxide in N,N-dimethylformamide (DMF) medium. In the process of synthesizing the starch sulfate, the optimum condition was obtained by measuring the sulfur content and the degree of substitution (D.S.) at the various conditions of suspending time in DMF, nitrosation temperature, sulfation time and sulfation temperature. In the sulfation, the reasction order, reaction rate constant and activation energy from Arrhenius plot were also investigated. Sodium starch sulfate was reacted with amine compound, e.g. ethylenediamine, in the presence of acid and the resulting product was identified by IR spectral analysis. On the other hand, sodium starch sulfate was reacted with the crosslinking agent, e.g. DMDHEU, in the presence of NH$_4$Cl catalyst and the resulting product was identified by IR spectral analysis.
