The Government Archives & Records Service collects the official document which is produced from the government offices system and it preserves. Currently the major general document quantity is 470,000 files(2000 years 3 end of the month), from in the that the document of Japanese General in Korea is 30,000 files degree. The document of Japanese General in Korea compares in whole major general quantity and hold the specific gravity which it does it writes but, quality to in the data at quantitative it will can use from the history researcher keeps the value which is important. The Government Archives & Records Service's Document or Japanese General in Korea is composed of 27 record group, and When seeing with the fact that it is a received document where the considerable portion of the document is not the production document, that possibility seems highly, bur The document of Japanese General in Korea is putting in the contents which is various, it keeps feed value which is important it will be able to confirm, 'region administration' and an irrigation association', prosecution of document' recording back from 1910 years until 1945 years it is produced the documents of most to be almost contained, the history value is nigh very. The data which is not the possibility of buying from the different which place it admits. The Government Archives & Records Service arranges government-general document which keeps the value which is important system and in order to preserve a many effort it tilts. It follows in quality of the file and it draws up a detail list with there to be it will be able to provide the bias of searching and reading, it becomes, it records the document with reader who easily it constructs the system search it will be able to apply the document which is necessary. The government-general document is applied but well to be respected history researcher the many interest is demanded.

Transgenic plants have been studied as delivery system for edible vaccine against various diseases. Edible plant vaccines have several potential advantages as follows: an inexpensive source of antigen, easy administration, reduced need for medical personnel, economical to mass produce and easy transport, heat-stable vaccine without refrigerator, generation of systemic and mucosal immunity and safe antigen without fetal animal-virus contaminants. The amount of recombinant antigens in transgenic plants ranged from 0.002 to 0.8% in total soluble protein, depending on promoters for the expression of interested genes and plants to be used for transformation. Throughout the last decade, edible plant vaccine made notable progresses that protect from challenges against virus or bacteria. However edible plant vaccines have still problems that could be solved. First, the strong promoter or inducible promoter or strategy of protein targeting could be solved to improve the low expression of antigens in transgenic plants. Second, the transformation technique of target plant should be developed to be able to eat uncooked. Third, marker-free vector could be constructed to be more safety. In this review we describe advances of edible plant vaccines, focusing on the yields depending on plants/promoters employed and the results of animal/clinical trials, and consider further research for the development of a new plant-derived vaccine.

이 연구에서는 소성힌지 구간 내에 유공이 있는 철근콘크리트 보의 전단성능을 평가하였다. 실험은 소성힌지 구간 내에 유공의 유무와 유공의 직경을 변수로 하였으며, 실험 결과 소성힌지 구간 내에 0.2D 이하의 유공을 설치하는 경우 유공을 충분히 보강하였다면 유공이 없는 실험체와 비교하여 동등 이상의 전단성능을 나타냄을 확인하였다.

이 연구에서는 유공이 있는 철근콘크리트 보의 전단성능을 평가하였다. 실험은 유공 유무를 변수로 수행하였으며, FEM해석 프로그램인 ATENA 3D를 이용하여 실험결과와 비교하였다. 실험결과, 유공이 있는 실험체는 유공이 없는 실험체에 비하여 낮은 전단 내력을 나타내었으며, 해석결과는 유공 유무에 관계없이 실험결과를 매우 정확히 예측하였다.

The preparation conditions of alumina powder extracted by hydrochloric acid from domestic San-Cheong kaolin have been investigated. In order to obtain best conditions to extract alumina by hydrochloric acid, experiments carried out with various acid concentrations, reaction temperatures, reaction times, and pH. The optimum conditions were 20 wt.-% for hydrochloric aicd concentration, 100℃ for reaction temperature, 7hrs for reaction time and pH8. The yield of alumina found to be 89.2wt.-% under these conditions. Two drying methods, direct and ethanol distillation drying method to control the precipitated agglomeration have deen compared. The ethanol distillation drying method revealed more narrow particle size distribution and less agglomerate than the direct drying method.
