한 유럽 시골마을에 세워진 "책의 고성"-벨기에의 '레뒤마을'
신창섭,Sin, Chang-Seop 대한출판문화협회 1994 출판저널 Vol.150 No.-
이 글은 "MBC가이드" 94년 5월호에 게재된 신창섭씨의 현장리포트 "유럽의 책마을 레뒤를 아시나요?"를 전재한 것이다. 한적했던 중부유럽의 한 시골마을이 어떻게 해서 애서가들의 순례지로 각광받게 됐는가를 보여주는 이 글의 전재를 기꺼이 허락해준 "MBC가이드" 측에 감사를 드린다.
금속산화물을 이용한 이산화황과 산화질소의 동시제거(Ⅱ) : 금속산화물과 이산화황의 반응 Oxidative Sorption of SO₂ by Metal Oxide
신창섭 한국산업안전학회 1991 한국안전학회지 Vol.6 No.4
To remove SO₂ from flus gas, cupric oxide, manganese oxide and iron oxide were studied with varying loading value. The experiment was carried out in a flow reactor and the reactants were prepared by impregnation method using alumina. The reaction temperature was varied from 300℃ to 450℃. Experimental results showed that all of these metal oxides were effective on SO₂ removal reaction and cupric oxide was the best reactant. The sample with 10wt% loading value was better reactant than with 20wt% because in case of 20wt% loading, metal dispersion on the alumina surface was not uniform. And the SO₂removal efficiency was increased with the reaction temperature.

To remove NO from flue gas, a direct decomposition method to N₂ and O₂ was investigated by using copper / zeolite catalyst. The copper ion-exchanged HY type zeolite has high activity on NO decomposition. The decomposition activity was increased with the increase of ion-exchange level, contacting time and reaction temperature in the range of 300℃-500℃, and decreased with the oxygen addition.

The release of gas from the LPG storage tank by the rupture or leakage can occure explosion and this causes serious damage to people and structures. In this study, the explosion effect and damaging distance were measured for the LPG cloud explosion to perform the quantitative risk assessment for the PSM, and the effective parameters on the explosion were found. The gas dispersion and mass contaminant in the explosion limits were calculated by using DEGADIS, and it was converted to TNT equivalency and damaging distance. As a result, the wind speed was the most effective parameter on the diffusion rate and TNT equivalency, and the damaging distance were increased with decrease of wind speed and surface roughness.
활성탄소섬유가 충전된 유기가스용 방독마스크 정화통의 흡착특성

The adsorption characteristics of a respirator cartridge is affected by the kind of adsorbent, concentration of organic vapor, humidity and packing density of cartridge. In this study, activated carbon fiber(ACF) instead of activated carbon is used as a adsorbent of cartridges for the removement of organic vapor and the adsorption characteristics were examined. ACF made of cellulose showes high efficiency for the removal of carbon tetrachloride and the adsorption capacity was 0.569g/g ACF at 450 ppm. The relative humidity dose not affected to the adsorbed amount and Langmuir Isotherm was more adequate than Freundlich Isotherm for this adsorption phenomena.

The paper discusses several means for estimating appropriating discount rates to value non-traded assets. That is, this study discusses the relationship between market equity beta and observable finance information in Korean capital market. The estimated relationship can in principle be used to determine betas for non-traded entity for which conventional market model or pure-play techniques are impractical. The applicability of the method can be illustrated by using it to estimate the common equity beta of non-traded firm. The result of this study is that Patterson's model is not valid for the assessment of the systematic risk in Korean capital market. That is, the coefficient of BREV, DOL and DFL are, respectively, not statistically significant and R^(2) is too low.
