尹載殖,金元燮 全北大學校 1987 論文集 Vol.29 No.-
Artificial intelligence(AI) is the study that makes the intelligent computer resembled human being. In this paper, we deal with the studying objects of Al classified fundamental field and application field, then we consider the application systems and the development trends of AI. Also, this paper described the application prospects of AI and formulated a set of measures to the computer industry in Korea, based on the application system and the development trends of AI.

In this study, the actual Survey, Correction and calculation for a triangular net were done the methods of triangulation and trilateration respectively, and their accuracies and consuming costs were compared by the results obtained from the above two methods. In conclusion it has been proved that the method of Trilateration is more advantageous than that of triangulation in terms of both accuacy and consuming costs.

This paper describes the experimental results for a Development of Fuel cell which is connected to a Generator system as a power-source. The fuel-cell power system model used in our experiments is composed of 2kW (100V, 20A rating) alkalielectrolyte H_2-air fuel cell and DC-AC converter. We carried out many experiments under the condition that this fuel-cell power system as a power source was connected with a simulated distribution network. We obtained its static characteristics and transient characteristics when voltage fluctuation or short-circuit failure occurred in the distribution network. From these results, We have found that fuel-cell power system is able to apply to a distribution system. And also, this paper describes basic matters and problems for conceptional design about a feulcell power plant to practical use. We investigate as following factor : ㆍapply points of a fuel-cell power plant in electric power system. ㆍtarget rating of a fuel-cell power plant. ㆍsystem composition of fuel-cells and inverter. ㆍrequired operational performance of its power plant. ㆍestimation of H_2-gas production methods. ㆍtechnical study problems in future We believe firmly that this paper is very useful when the utility introduce a fuel-cell power plant as a power source in electric power system.
混和劑에 依한 흙·시멘트 龜裂防止 效果에 對한 硏究 (Ⅱ)
尹載殖 全北大學校 1980 論文集 Vol.22 No.-
There are various causes of crack in the Soil-Cement which has been stable handling. But, among them, the cause of drying-contraction which was happened by the hydraulic operation of cement comes to the greatest effect. This study is the test to reduce the degree of the drying-contraction using the Admixing-Agent. The Admixing-Agents used in this testing are lime and Fly-Ash. Making the molds, the writer experiments the degree of drying-contraction in a laboratory.
Direct Stiffness Matrix에 의한 線型트러쓰 構造物의 解析
尹載殖,崔外鎬 全北大學校 1969 論文集 Vol.11 No.-
The direct stiffness matrix method has gained prominence in the last decade decade mainly for determining internal forces and displacementsof highly redundant strctures. A computerized analytical approach, using the direct stiffness matrix method, is developed for plane and space truss andtwo examples are solved for each truss. This method is more concise than the other matrix methods. Therefore the computer program data input are greatly simplfied.

Pure tantalum powder has been produced by combining Na as a reducing agent, $K_2$TaF$_{7}$ as feed material, KCl and KF as a diluent in a stainless steel (SUS) bomb, using the method of metallothermic reduction. And we examined various types of after-treatment that affect the high purification of powder. A significant amount of impurities contained in recovered powder was removed in various conditions of acid washing. In particular, 20% (HCl + HNO$_3$) was effective in removing heavy metal impurities such as Fe, Cr and Ni, 8% H$_2$SO$_4$ + 8% $Al_2$(SO$_4$)$_3$ in removing fluorides such as K and F from non-reactive feed material, and 2% $H_2O$$_2$ + 1 % HF in removing oxides that formed during reaction. Significant amounts of oxygen and part of light metal impurities could be removed through deoxidation and heat treatment process. On the other hand, because it is difficult to remove completely heavy metal impurities such as Fe, Cr, and Ni through acid washing or heat treatment process if their contents are too high, it is considered desirable to inhibit these impurities from being mixed during the reduction process as much as possible.
원료물질과 환원제의 외부공급에 따른 탄탈륨 분말의 제조 및 특성
윤재식,박형호,배인성,김병일 한국분말야금학회 2003 한국분말재료학회지 (KPMI) Vol.10 No.5
This study examined the correlation of various operational factors including reaction temperature and the quantity of reductant and diluent with the characteristics of powder using $K_2$ TaF$_{7}$ as feed materials, Na as a reductant and KCl/KF as a diluent. Also to control the particle size and shape, external supply system developed, it can provide a feed material and a reductant at a fixed quantity and evaluated the characteristics of tantalum powder. When the external supply system was applied instead of the batch type process that charges feed material, reductant and diluent at the same time, it was possible to induce regular reduction reaction between feed material and reductant, which increased the recovery rate and reduced the mixture of impurities. In particular, the application of the external supply system enabled the control of reaction temperature and reaction speed according to the feeding rate of feed material during reduced reaction, and resultantly it enabled the manufacturing of granular-shaped powder with a regular granularity of 2∼3 ${\mu}{\textrm}{m}$ and purity of 99.5%.
