김종희,이재영,박용기 대한금속재료학회(대한금속학회) 1977 대한금속·재료학회지 Vol.16 No.1

Ti-Al 합금과 수소의 반응에서 aluminum이 반응속도에 미치는 영향을 알기 위해 온도 범위 670℃∼800℃와 3Torr의 수소 압력에서 thermogravimetric 방법으로 Ti-Al 합금과 수소의 반응 속도를 측정했다. 순수한 titanium과 수소의 반응 속도를 지배하는 단계는 titanium 내에서의 수소확산이었으며 aluminum이 0∼7.5at.% 첨가된 합금에서도 수소와의 반응속도는 합금에서의 수소 확산에 의해 지배됨을 알았다. Fick의 확산 방정식을 풀어 순수한 titanium α상에서의 수소 확산 계수를 구하였다. 수소확산 계수는 온도 함수로 다음과 같이 표시된다. D(㎠/sec)=3.70×10^(-2)exp(-14,400±450)/RT) 또 aluminum이 6at.% 첨가된 Ti-Al α 합금에서의 수소 확산계수는 다음과 같다. D(㎠/sec)=2.79×10^(-2)exp(-17,400±410)/RT) Kinetics of the reaction of hydrogen with titanium and Ti-Al alloys have been studied in the temperature range of 670℃-800℃ at % Torr hydrogen pressure using thermogravimetric method. It is found that the reaction controlling step of the two systems is hydrogen diffusion in metals. The diffusion coefficients of hydrogen in pure titanium and Ti-6 at.% Al alloy are D(㎠/sec)=3.70×10^(-2)exp-(14,400±450)/RT) and D(㎠/sec)=2.79×10^(-2)exp-(17,400±410)/RT) respectively. Aluminum decreases makedly the diffusion coefficient of hydrogen. It can be probable explained by that aluminum decreases the interstitial site of titanium lattice.

인터페이스 공간의 참여 프로그램에 관한 연구

김종희,유진형 한국공간디자인학회 2009 한국공간디자인학회논문집 Vol.4 No.1

디지털 기술의 발달이 가져온 인터페이스의 진화는 엄청나다 이와 관련하여 상공간과 같은 실제 생활 공간에서는 어떻게 인터페이스가 구현되고 있는가, 그리고 앞으로 어떤 방향의 인터페이스 개발이 바람직한 것일까? 상공간의 인터페이스를 디자인 하는데 있어서 사용자가 참여할 수 있는 프로그램을 구현하는 것은, 디지털 가상 인터페이스의 참여라는 장점을 현실 공간에서 구현한다는 점에서 의미가 있다. 디지털 첨단 기술을 이용한 고비용의 인터렉티브 공간이 아닌, 일상 상공간에서 실현이 가능한 공간내 참여 프로그램이 필요하며 그 가능성은 열려있다. 사용자가 참여하는 공간 프로그램과 이를 반영한 인터페이스는 공간을 사용자 입장에서 긍정적으로 바꾸고, 공간의 가치면에서는 공간을 더욱 유연하고 풍부하게 바꿀 수 있기에 미래 상공간의 중요한 특성이 될 것이라고 본다. Interface has evolved significantly since digital technology has developed. With the relation to the fact, how have living spaces been expressed and what would be better future of the interface development? It seems to be meaningful making a virtual program which enables users to participate in designing a real commercial space. Because there is an opportunity that users can take part in making their own living space by applying the virtual program rather than spending lots of cost on utilizing state-of-the-art digital technology. It can be concluded that the virtual program would be valuable in that users can make their space in the way they want and the space could be utilized much more efficiently and flexibly.

On the hypothesis that Calvin's doctrine of predestination is the Trinity-centered one, neither God-centered one, nor Christ-centered one, not Holy Spirit-centered one, we examined it, and we can arrive at the result as following. The ultimate cause of predestination is the will of God, the basis of election is Christ, and the sign of predestination is related with the work of Holy Spirit, being with the elect, and not being with the reprobate. Therefore we may say that Calvin's doctrine of predestination is Trinitarian one, and this means that the works of the Trinity in the decree and the execution of predestination, which are distinguished without division among the works of the three persons of the Trinity, are emphasized.

地方交付制度의 問題點과 改善方案

현재 우리나라에서 운영하고 있는 지방재정조정제도에는 방교부세제도, 국고보조금제도, 지방양여금제도가 있다. 그러나 이들 각각의 특성이 분명하지 않아 제도의 투명성이 부족하고 제도운영의 목표와 이에 따른 적절한 수단이 정확하게 연결되어 있지 않아 효율성이 의문시되고 있다. 지방교부세제도는 지방자치단체의 세입과 세출간의 불균형, 지역간 재정력 격차의 해소라는 목표를 위해서는 가장 우수한 제도이나 특정 공공재 공급의 확대를 위한 방법으로는 가장 열등한 방법이다. 교부세 재원 중 일부는 특별교부세와 증액교부세라고 하여 국고보조금과 같은 형태로 배분되고 있어 제도의 투명성과 효율성을 저해하고 있다. 그리고 측정 항목들이 해당 예산과목의 일부만을 포함하고 있기 때문에 산정되는 기준재정수요가 전반적인지 방재 정 수요를 반영 하지 못하고 있다. 이러한 문제들을 해결하기 위해서는 지방교부세의 배분방식을 단순화하고, 법정교부세율을 단계적으로 상향 조정 하며 , 지방교부세 배분에 있어 신축성을 제고하며, 보정 계수 기능을 강화하여야 한다. 그리고 재정지출규모가 큰 지방자치단체에 많은 교부금이 지원되고 지출삭감을 위해 노력하는 지방자치단체에 적게 교부되는 폐단을 시정하기 위하여 교부금체감제도를 도입하는 방안도 고려 해 보아야 한다. The total steam generator leakage limit for all steam generators ensures that dosage contribution from the tube leakage will be limited to a small fraction of 10 CFR 100 limits. The leakage limit per steam generator is intended to assure that steam generator tube integrity is maintained in the event of a main steam line rupture or under LOCA conditions. Analytical assessments through EPRI procedures revealed that the present leakage limit of 10 ℓ/hr have assured the steam generator tube integrity of Ulchin nuclear power plant. Therefore it is not necessary to lower the allowable leak rates further but to establish its own allowable leak limits based on the plant operation history.

소나무의 monoterpenoids가 질화작용에 미치는 영향

강호남,김종희 慶南大學校 附設 基礎科學硏究所 1998 硏究論文集 Vol.12 No.-

The nitrification processes (ammonium oxidation and nitrite oxidation) were investigated to evaluate the role of monoterpenoids in Pinus monoterpenoids (β-pinene, sabinene and camphene) on nitrification. Among nitrification processes, the ammonium oxidation process has no relations with the amount of monoterpenoids, but the nitrite oxidation process was inhibited by the presence of monoterpenoids in soil. β- pinene should not be inhibited in nitrification, but sabinene and camphene should be inhibited nitrification.

This is a study of the physiological nutrition source of Alternaria panax which causes a disease in the leaves of ginseng. The effects of hydrogen Ion concentration, trace element source of metal and inorganic nutrition on the growth of this fungus have been obtained. The effects of optimum hydrogen Ion concentration on the growth of this fungus in Waksman and potato liquid extract medium were respectively 5.5-6.0 and 4.0∼4.5 The hydrogen Ion concentration after culture altered its formal medium concentration; the strong acid changed into weak acid, and the strong alkali into weak alkali. The effects of number of thiamine concentration on the growth of this fungus were much enhanced when 16r thiamine concentration were added in the basal medium per 20cc, and the fungus growth in the thiamine control basal medium appreciably decreased. The hydrogen Ion coucentration changed a little bit into acidity. The effects of several kinds of biotin concentration on the growth of this fungus were progresed significantly when 20μr biotin per 10cc and 0.1PPM thiamine were added to the basal medium and the growth diminished when biotin control medium and 100μr biotin concentration were added. When the basal medium was supplemented with simple vitamine or a thiamine to each simple vitamine, the effects of each vitamine on the growth of this fungus showed that biotin and thiamine were best in each vitamine unit, and when the calcium chloride and the control of vitamine were matched, the effects were poor. In the case of calcium pantothenate added to thiamine, the growth was much enhanced but in case of calcium chloride added to thiamine, the growth was poor results. When thiamine each simple vitamine concentration was added in the basal medium generally the growth was much better than in the case of added to each vitamine concentration. In a mixed concentration boiled oatmeal extract medium was most effect on the growth of fungus, and the control of mixed or simple vitamine showed poor results. The hydrogen Ion concentration was changed appreciably into weak acidity. As for the effect of minimum metal source on the growth of fungus, an optimum Mol concentration of ferric chloride, Natrium molybdaenicum, zinc sulfate and Manganese sulfate were different in each Mol concentration: the ferric chloride was 1/1,000 Mol, natrium molybdaenicum 1/60,000 Mol, zinc sulfate 1/8,000 Mol and manganese sulfate also 1/10,000 Mol. The range of hydrogen Ion concentration after culture was generally changed into alkali region. As for the effect of inoganic nutritional elements on the growth of the fungus, the optimum range, the potassium phosphate monobasic, dibasic was 0.05%, magnesium sulfate 0.075%and calcium chloride 0.025%. Also all control of inorganic nutritional elements have showed unfavorable effects. The hydrogen Ion concentration was altered its formal hydrogen Ion concentration into weak acidity but majnesium sulfate was changed into weak alkali.

The effect of firing temperature, soaking time and batch composition upon the glass phase and pore formation as well as their distribution in slag foamed glass was investigated. Sulfur dioxide gas produced by the oxidation and reduction of metal sulfide in waterslag was attributed to foam forming agent. Slag foamed glass matrix was mainly composed of 35~60% glas phase and melilite crystalline phase. The increment of bentonite addition in batch lowered the foam forming temperature in studied system. The result showed also that the foam size distribution was broadened as th firing temperature wa inbereased.
