이동길,윤용익,최광무,전길남 한국정보과학회 1985 한국정보과학회 학술발표논문집 Vol.12 No.1
본 연구에서는 ESS 개발환경을 고려하여 Production Quality CHILL Compiler 개발의 환경조성을 위한 prototype CHILL subset compiler 을 설계 제작하였다. KAIST parser generating system 등을 이용하여 front end 을 설계 제작하였으며 Amsterdam Compiler Kit 으로부터 back end 와 intermediate machine 의 환경을 제공받아 CHILL subset 을 위한 prototype compiler 을 설계 제작하였다. 아울러 CHILL 의 concurrent facility 들을 위한 CHILL monitor을 설계 제작하였다.
광미적치장의 최적 처리방안 선정을 위한 경제성 분석 연구

Economical analysis has been conducted for the selection of a economical and effective method of treating tailing dam. Treating methods can be classified into 3 groups, namely consolidation, refilling and take-out methods, consisting of a total of 8 methods. As a result of estimating the net present value and sensitivity analysis of all the methods, mine green framework (MGF) and soil cement wall (SCW) methods were determined to be more economical than the others. Based on more thorough assessment from an economical and technical point of view, MGF was finally chosen as the optimum method between the two.
The pH Effect for Rare Earth Metals Nd, Pr and Y in Aqueous Solution Dissolved Mg, Zn and Al
이동길,정원섭,김용환,이인원,전호환,박현 대한금속·재료학회 2010 METALS AND MATERIALS International Vol.16 No.5
The pH variations of Mg, Zn and Al solutions to which had been added the rare earth metals Nd, Pr and Y were observed in 3.5 wt.% NaCl with respect to high energy mechanical ball milling effects. Mg was directly dissolved and exhibited a pH value of 10.5. On the other hand, Zn and Al needed to be saturated for a certain amount of time. The addition of rare earth metals played a role in increasing the pH with low reduction potentials. Additionally, mechanical ball milling provided high energy to Mg + x wt.% Zn + 0.5 wt.% Nd mixture by fracturing fragmentation of metals, which led to an increase in the pH when the mixture was immersed in 3.5 wt.% NaCl. The addition of Zn to Mg + 0.5 wt.% Nd caused a higher pH than when Mg + 0.5 wt.% Nd alone was added.
