Three kinds of domestic clay were selected, purified, through chemical methods and fractionated at different particle size. And thus fractionated clay particles less than 2μof each sample were taken for the measurement of Electrio phoretic mobility in oder to investigate its solid-liquid interfacial. electro chemical character. The electro phoretic mobilities of all the samples showed increased values with increasing PH values suspensions. This was considered as the surface of particle samples were charged negatively. The Hadong sample, Na-saturated after H_2O_2 treatment, indicated its equi potential at PH 2.6 of suspension. The Young-il sample made a little lower electrophoretic mobility when it was Na-saturated after H_2O_2 treatment than was only treated with H_2O_2.

姜濚義 順天大學校 1986 論文集 Vol.5 No.1

PET纖維의 energy절약형 染色法을 개발하기 위해 시도해본 常壓染色과 2相染色에 대한 染色性을 考察한 結果는 다음과 같다. 1. biphenyl/methylene chloride溶液의 常溫에서 처리한 PET의 結晶化度가 增可한 것같이 2相染色에 있어서도 같은 現狀을 나타냈으며 染着量의 向上의 原因이되고 있다. 2. biphenyl의 添加量에 따라 染色性이 向上되었으며 mecl₂系에서의 경우가 가장 컸다. 따라서 energy절약형 常壓分散染色은 5% biphenyl/mecl₂溶液에 21℃ 45초 처리한 PET섬유의 染色性이 가장 효율적이었다. 3. 100℃에서 Disperse Red 4에 의한 2相染色은 染料가 완전하게 용해된 溶劑相에서 水相에 보급되므로 染料濃度를 一定하게 유지할 수 있어 均染染色과 小용比染色의 硏究가 가능하며 溶劑로서는 Toluene Perchloro cthylene, Xylen 등이 유력시 되고 있다. Atmosphenic disperse dyeing and 2 phase dyeing properties of poly(ethylene terephthalate) fiber with C.I.Disperse Red 4 were investigated. The crystalline growth of PET fiber treated with bipheny / methylene chloride and 2 phase dyeing were also greater treated with other solutions. Equlibrium dye absorption and initial rate of dyeing of PET fiber treated with 5% biphenyl / methylene chloride and 2 phase dyeing were grater than those of sample with other solutions. I think that dyeing method of energy conservation of preated PET fiber is dyeing PET fiber preated with 5% biphenyl / methylene chloride and 2 phase dyeing. The solvents of 2 phase dyeing are toluene, m-xylene. perchloroethylene monochlorobenzene.

The study is on the traditional textile production, traditional dyeing and the formal dress through the field reserch concerning the folk attitude toward dress style around the Sunchon area. The formal dresses, which people wore on particular occasions such as the wedding clothing, shroud and mourning dresses, were very meager due to poor living standarded. People could not the formal dresses with full decoration. Bride and bridegroom wore the village owned wedding dresses, and if they could not afford to, they simply put cloth on to remember the occasion. In this area, people produced and wore hemp, cotton and Ramie only for self-sufficiency. At the present time the hemp cloth land is created in Bosung area and its products are made. As they are in increasing demand, their prospects seem to be very bright. The indigo plant dyeing as traditional dyeing has been done in this area because of natural condition good for dyeing, and recently natural dyeing by extracts from gardenia or hongwha etc. comes to spread. In consequence of this study, the fact is that our traditional costume is disappearing with the westernization. However, the development and inheritance of our traditional dyeing method and traditional textile production will take back to us ours.

강영한(Yeong-Han Kang),박종삼(Jong-Sam Park) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.4

본 연구는 임상에서 시행되고 있는 64 절편 다행검출 CT(MDCT)의 방사선량에 대해 알아보고 이 선량으로 인한 암 발생의 잠재적 위험(LAR)을 정량화하고자 하였다. CT 검사의 선량길이곱과 유효선량을 측정하였고, 이로 인한 암 발생 귀속위험은 미국 전리방사선의 생물학적효과 위원회 7차보고서를 이용하였다. 결과에서 두부 CT의 유효선량은 l.48mSv, 흉부 CT(조영제 포함)의 유효선량은 7.66mSv였으며, 복부 역동적 CT는 24.52mSv였다. 두부 CT의 LAR은 남성 7463명 중 1명, 여성 4926명 중 1명이었고, 흉부 CT (조영제포함)의 LAR은 남성 1449명 중 1명, 여성 952명 중 1명이었으며, 복부 역동적 CT는 남성 453명 중 1명, 여성 298명 중 1명이었다. 따라서 64 절편 MDCT 검사는 암발생위험과 무시할 수 없는 관련성이 있었고, 선량을 줄이기 위해 프로토콜 등을 조정하는 등의 세심한 노력을 기울여야 한다. This study was to estimate the radiation dose associated with 64-slice multidetector CT(MDCT) in clinical practice and quantify the potential cancer risk associated with these examinations. Lifetime attributable risks(LAR) were estimated with models developed in the national Academies' Biological Effects of Ionizing Radiation Ⅶ report. Mean effective dose were 1.48mSv in Brain axial scan, 7.66mSv in chest routine contrast, 12.l7mSv in coronary angiogram, 24.52mSv in Dynamic abdomen scan. LAR estimates for brain routine varied from 1 in 7463 for man to 1 in 4926 for women. In chest routine with contrast, LAR varied from 1 in 1449 for men to 1 in 952. LAR of Abdomen dynamic CT varied from 1 in 453 for men to 1 in 298 for women. So, 64-slice MDCT scan is associated with non-negligible LAR of cancer. Doses can be reduced by careful attention to scanning protocol.
