Detergency is the action of imparting from an undesirable soiled substance. One of the largest applications of detergents is for cleaning of hair skin. Generally, shampoo is a hair care product used for the removal of oils and dirt substance. In this study, detergency of soiled fabrics using PEG hydrogenated castor oil used to be dry shampoo. At first, detergency of soiled fabrics with ethanol was examined. In the best physical properties of ethanol, detergency of soiled fabrics from PEG - 20, 40, 60 and 80 hydrogenated castor oil was tested with Terg - O - Tometer. The detergency was analyzed and compared through the Gravimetric and contact angle. Gravimetric method was able to measure of detergency easily and simply. Contact angle analysis was used to compare good detergency. As results, it was shown that detergency of PEG - 20 hydrogenated castor oil in 60 % ethanol was 11.5 %. In this point, contact angle difference of soiled water was 2.32 ˚. 0.4 g PEG - 20 hydrogenated castor oil in 60 % ethanol was effective for detergency, but the detergency value was limited

이 연구는 제7차 교육과정기의 과학 교과서와 실험관찰 교과서에 제시된 삽화를 성역할 고정관념 측면에서 분석하고 6차 교육과정기의 과학 교과서와 비교하였다. 교재에 나타난 삽화에서 성별에 따른 등장인물의 빈도를 세고, 활동 유형을 분석하였다. 연구 결과는 다음과 같다. 1) 과학 교과서의 전체 삽화 수는 6차에 비해 7차에서 2배 정도 증가하였다. 2) 아동의 경우 학습활동에서는 성에 관계없이 등장 빈도가 대체적으로 균형을 이루었지만, 학습의 활동에서는 남학생의 등장 빈도가 여학생보다 더 높았다. 3) 행동 특성에서는 남녀 학생 모두 적극적으로 묘사되었고, 소극적으로 묘사되는 여학생의 비율은 6차 과학 교과서에 비해 감소하였다. 4) 성인의 경우에는 남성의 등장 빈도가 여성보다 높게 나타났다. 5) 가사 활동을 하는 모습에서는 여성의 등장 빈도가 40%로 높게 나타난 반면, 남성은 드물게 나타났다. The illustrations in elementary science textbooks and experimental workbooks based on the 7th national curriculum were analyzed for gender-role stereotyping, and compared with those of the 6th curriculum. The frequencies of men and women who appeared on text illustrations were counted and the types of roles assigned to males and females were investigated. The results were as follows. 1) The 7th national curriculum textbooks contained double the number of illustrations in the textbooks based on the 6th curriculum. 2) Boys and girls were illustrated in 'learning activities' with equal frequency, but boys were more frequently represented than girls in illustrations of 'other' activities. 3) Both boys and girls were generally depicted in 'active' processes and the ratio of 'passive girl' illustrations decreased as compared with the 6th national curriculum. 4) Male adults were more frequently represented than female adults in both textbooks and experimental workbooks. 5) 40% of female adults were illustrated doing housework, while male adults were rarely illustrated in such a role.

Tumor-infiltrating lymphocytes ('1°ILs) interact most closely with tumor cells and thus are more likely to reflect tumor host interactions accurately. But it is unknown whether such T cells are nonspecific inflammatory cells or a subset of specific host immune responses. In this study, there was no clear correlation between the infiltration of T lymphocytes in stomach cancer and the overexpression of c-ErbB-2 or increasing class I MHC expression on tumor cells. A positive correlation was seen between the presence of TILs in the tumor and tumors with diploidy by flow cytometric DNA analysis. The proliferative responses of Ills stimulated with IL-2, anti-CD3 mAb, or both were examined. When compared to normal mucosal-associated lymphoid tissue lymphocytes, the proliferative response of TILs to high dose IL-2 was minimal. A similarly poor response to anti-CD3 mAb plus IL-2 was also observed. The freshly isolated TILs exhibit reduced ability to proliferate in response to IL-2, anti-CD3 mAb or both. The microenvironment of the tumor suppresses the proliferative capacity of the TILs. The mechanism of this suppression remains unknown. It could be mediated by suppressor cells, by soluble substances within the tumor, or both. To examine this question, supernatants of stomach cancer cells (SNSNU-1) were tested for the presence of immunosuppressive factors. Human peripheral blood T-cells and tumor-draining lymph node lymphocytes (TDLNL) were incubated for 3 days with SNSNU-1 and then assessed for proliferative responses to PMA, anti-CD28 mAb, or both and for the inducibility to express IFN- r or IL-4 mRNA to PMA. Peripheral blood T-cells pretreated with SNSNU-1 were unable to proliferate in response to PMA, anti-CD28 mAb or both. SNSNU-1 also produces inhibitory activities of TDLNL proliferative response to PMA or anti-CD28 mAb and PMA (49%, 52%, respectively). In contrast, culture supernatants obtained from HEp-2, K562 or Daudi showed normal proliferative responsiveness of peripheral blood T-cells and TDLNL by PMA, anti-CD28 mAb or both.

Korean railroad has been an industrial artery of the country for a long time and has played enormous roles in the transportation of passengers and goods. As a result, this sector has been striving for a continuous improvement in various aspects of the train in order to provide a better service to all passengers. This pattern of improvement can be observed in two broad categories: Electric components and mechanical components. However, in the process of improvement, some problems have occurred due to more complicated system structure, In electric components such as air conditioning units, lighting devices and other subsidiary devices, there occasionally shut off the electric line by the over current relay due to the switches and/or contactors caused by instant failure of the device trouble. The other case is mechanical components such as driving systems and braking devices, there are abnormal condition which are attacked other substances(eg. dust), burst in rubber contact panel, cracked, in welded pipes...etc. Even though, nowadays less, those problems have been minimized significantly in recent year aim to feel more comfortable and softer. So, this paper bases on this motive and analyses into the train examines the current state as well as the main factors causing system fault. It has been reported that train entrance doors and associated rollers are the most fault-prone component. Hence a detailed analysis was undertaken in this particular topic. By it analysis produced valuable insights on how to further improve the current system. It is expected that such preventive maintenance will improment overall quality of the service before faults.

To create good urban environment using old agricrltural crops, eight old crops were evaluated for growth and pollution injury at five districts in Seoul. The results are summarized as follows ; 1. In investigation of ten air pollutants in July and August, it was detected heavy contents at Kuroku districts, while Kwangzinku and Songpaku showed the least contents. There have resulted SO2 to be the most detection in Kuroku during experiment period. Whereas O3 showed them the most at Songpaku in August, while it was Soedaemunku in July. In dust content, Kuroku had the least in July, while Yongsanku was in August. 2. In the growths during three months of five districts in Seoul, Nicotiana tabacum was the worst, while five crops such as Perilla frutescens, Ricinis communis, Zea mays, Sorghum bicolor, Cassis tora were the best for growth. Yongsanku out of five districts was the worst them in general, however, there were the best growth in Sedaemunku. Perilla frutescens, Sorghum bicolor, Loix mayuen showed good overall everywhere. In pollution injury, it was quite different from distticts and crops, there showed more 3.0 grade of severe infury Gossypium nankion at Songpaku, Cassia tora at Kuroku, Nicoriana tabacum at Kuroku and Songpaku respectively. There were shown at Kuroku and Songpaku to be the heavy injury while three districts such as Seadaemunku, Yongsanku, Kwangzinku showed a little injury. 3. In contents of sulfur absorption in leaves among them, they were quite different from districts and crops. Sorghum bicolor, in Kwangzinku absorbed it the most, whereas there were the least it in Seodaemunku and Songpaku. Sorghum bicolor was the most absorption for it at Kwangzinku, while Ricinus communis at Kwangzinku, and Zea mays at Seodaemunku were analyzed the least for them. 4. Pollutant that showed overall the highest correlation coefficients with plant growths was O3, next was SO2 and NOx in order of them. The most crops had high correlation coefficients with O3. The crop which had high correlation coefficients for growth with O3 was particulary Perilla frutescens. They had correlation negatively between them in plant height, and plant width, while there were positively correlation between them with pollution injury. Sorghum bicolor showed also th have high correlation with O3, and Ricinus communis negatively correlation between O3 and plant width, and to have correlation positively between dust contents and no. of branches. Zea mays also gave results positively high correlation between O3 and injury leaves due to pollution while there were negatively high correlation for growth with it. Cassia tora showed also positively high correlation between pollution injury and O3.

We manufactured and characterized different sets of GaAs/AlGaAs multiple quantum well structures for the long wavelength infrared photodetection. The samples were grown by MBE. We changed the aluminum composition of barrier region from 0.24 to 0.30 in 0.02 steps, and performed double crystals X-ray diffraction(DCXRD) and the photoluminescence measurements. DCXRD measurements correctly gave the expected aluminum compositions. Photoluminescence measurements revealed that the ground state energy of the well increases with composition as desired, but the change was not very significant.

Of all facial fractures in children, condylar fractures have the greatest propensity to produce a growth disturbance. The pediatric condylar fracture occurs very frequently in the mandible, but this injury is occasionally ignored due to difficulty of diagnosis and no cooperation of patient. The adequate initial diagnosis and active treatment must be performed because delayed and improper treatment lead to possible severe complications such as facial asymmetry, TMJ pain, limiation of motion and deflection, midline deviation of the dental arch. So, the goal of managing condyle fractures in the growing patient is to restore mandibular symmetry, occlusion, function without interfering with future growth. Commonly, fracture teatment aims at restoring function through repositioning and rigid fixation of the bony fragments. However, the generally preferred management of condylar fractures in growing children is nonsurgical. So, we present the clinical and radiographic follow-up results of 4 condylar fractures in pediatric patients whom we managed in conservative and functional method. We can summarize our protocol in management of pediatric condylar fracture as the following: The IMF using acrylic resin splint with circumferential wiring was performed for 1 or 2 weeks. After releasing IMF, the active physical therapy was done with guiding elastic band. Opening deviation was controlled by mannual pressure of surgeon or parents for 2 weeks. When unstable occlusion or functional problem remained, functional appliance after construction bite registration was used for several months.
