  • This study is the investigation of dressing the deceased Kings and the King's robes in the coffin in the Yi Dynasty of Korea. The Authentic Records of the Yi Dynasty and the Diaries of Sung Jung Won (承政院日記) are mainly referred to as the research materials. The Concrete contents are the robes of the 20th King Kyung long (景宗 : $1720{\sim}1724$) to the 23rd King Soon Cho(純祖 : $1800{\sim}1834) in the Yi Dynasty. As the result of the study, the kinds of the robes in dressing the decreased Kings and the Kings' robes in the coffin are more than forty. The kinds of textile fabrics are about fifty-seven, the kinds of colours of textile fabrics are twenty-nine. All the kinds of costume-from the Kings' ceremonial robes to the Kings' ordinary robes are generally collected, and these kinds of costume are of help for the study of the costume history in the Yi Dynasty. In this study I intend to end in presenting the research materials, and in the later study I have a mind to study each costume in the concrete.

  • Using zirconium ceramics makes the ferrule, which is the part of optical communications. The quality of optical communications is directly affected by the concentricity of the optic ferrule. The products of optic ferrule should be meet the following general conditions which are the outer diameter of 2.5mm and the inner diameter of 0.125mm, and high quality conditions which are the concentricity of 0.1~$0.3\mu\textrm{m}$, the form accuracy of $0.2\mu\textrm{m}$, the roundness and the cylindricity of $0.1\mu\textrm{m}$ and the surface roughness of 10nm. Generally, the diamond wheel is used for the high efficiency and precision grinding of the materials. It is good for keeping the shape as it has little wear. Because of the loading phenomena, however, it is difficult to keep the fresh surface of the wheel. In grinding process, grinding fragments resemble fine powders rather than chips. It can easily get attached to the wheel surface and thus cause a loading. The loading takes place, in which the impurities stick to the wheel surface, and the grinding characteristics of wheel is deteriorated. To prevent all of these, a suitable dressing method should be used for the wheel. In this research, the dressing system fur co-axial grinding machine was designed and produced for the machining of ferrule, which is a high performance part. The performance of the developed dressing system was evaluated by measuring the form accuracy of ferrule, which is machined by the dressed wheel in developed dressing system.

  • Chipping is an unavoidable phenomenon in the slot grinding process of hard and brittle materials. However, it should be reduced for the improvement of surface integrity in the manufacture of optical and semiconductor components. Electrolytic In-process Dressing (ELID) technique for metal bonded superabrasive grinding wheel has been developed for mirror surface grinding of hard and brittle materials. Electrically dressed wheel surface has sharply exposed abrasives and results in lower grinding force, higher grinding efficiency in grinding. The paper deals with a newly developed method for slot grinding using ELID and was implemented to improve grooved surface quality and decreases chipping size on the edge of the groove. As a result, we accomplished chipping-free grooves and obtained the clear ground surfaces on glass and WC.

  • This study was conducted for the optimization of ingredients in salad dressing using Hwangdo peach (Prunus persica L. Batsch). The experiment was designed according to the D-optimal design of mixture design, which included 14 experimental points with 4 replicates for three independent variables (olive oil 40~65%, peach puree 27~50%, vinegar 8~20%). The linear regression models for pH, viscosity and color value and the quadratic regression models for emulsion stability, all sensory evaluation of the products were proven to be valid by the F-test for the overall significance of the regression model at a 5% level. Viscosity and pH of the products increased as olive oil content. Color value, viscosity and pH of the products increased as peach puree content. pH, viscosity, redness, and yellowness of the products decreased as vinegar content. Sensory evaluation result of the products showed that general preference for the products were increasingly affected by the increases in contents then decreased as they exceeded the optimum levels. In consequence, according to result from the first stage of the experiment, the optimum ingredients ratios of the raw materials were set in olive oil 52.43%, peach puree 35.07%, and vinegar 13.91% for ingredients of apricot dressing. These results provided the possibility that peach can be applied to the preparation of a dressing, and thereby present baseline data for the development of new dressings. This is also presumed to meet demands of customers who are always in pursuit of new products.

  • 개의 전층피부 창상에서 삼출물의 정도와 창상수축, 상피화, 그리고 치유에 대해 hydrocollodi(Duoderm/$\circledR$, HC)과 hydrogel(Nu-Gel$\circledR$, HG) occlusive dressing materials 의 효과를 비교하였다. 3쌍의 정사각형 전층피부 창상을 2${\times}$2cm 의 크기로 12마리 개의 몸통 등외측 면에(6개의 창상/한 마리) 만들었다. HC와 HG, 생리 식염수(대조창)를 무작위로 배분한 2개의 창상에 각각 적용하였다. 창상의 육안적 소견과 병리조직학적 소견을 4주 동안 평가하였다. 창상유발 7일 후, 비교 그룹 간의 평균 창상수축 정도, 평균 상피화율, 평균 창상 치유율에 유의성있는 변화가 관찰되지 않았다. 창상 유발 14일(P<0.01)과 21일(P<0.05) 후, HG 처치창의 평균 상피화율이 HC 처치창의 평균 상피화율과 대조창의 상피화율보다 유의적으로 더 높게 나타났다. 창상 유발 21일 후(P<0.05), HG 처치창의 창상 수축율이 HC 처치창의 평균 창상 수축율과 대조창의 평균 창상 수축율보다 유의적으로 더 높게 나타났다. 창상 유발 21일 후(P<0.02), HG 처치창의 창상 치유율이 HC 처치창의 평균 창상 치유율과 대조창의 평균 창상 치유율보다 유의적으로 더 높게 나타났다. 창상 유발 1, 4, 7일 후, HC 처치창과 대조창의 피하에 다형핵 백혈구의 심한 침착이 관찰되었고, HG 처치창의 피하에 중등도의 다형핵 백혈구의 침착이 관찰되었으나, HG 처치창, HC 처치창 간의 어떠한 유의적인 변화도 발견되지 않았다. 창상 유발 14일 후, HG 처치창에서 상피성 세포가 유의적으로 표면 위로 자라났고, 부종은 창상 밑 조직까지 감소하였으며, 육아조직은 교원질 섬유로 대체되었다. 창상 유발 21일 후, 다른 창상에 비해, HG 처치창은 유의적으로 창상 표면이 거의 재생성 상피로 덮였으며, 육아조직은 창상 유발 14일 후와 비교해서 유의적으로 교원질 섬유로 대체되었다. 위의 모든 결과에서 보듯이, 개에서 전층피부 창상의 처치 시 HG의 사용은 HC와 생리 식염수에 비해 창상치유 복구기의 치유 속도를 촉진하는 것으로 사료된다.
