본 연구는 미취학 어린이를 대상으로 손씻기 교육 방법에 따른 미생물학적 변화를 모니터링한 연구이다. 연구는 3세에서 5세까지의 서울시 어린이집 어린이 10명을 대상으로 수행하였다. 미생물 분석은 손씻기 교육 전, 1주간 동영상 교육실시 후, 1주간 동영상 교육 및 손씻기 실습 교육병행 후로 분류하였다. 손씻기 교육 전 어린이들의 손에서는 일반세균, 진균, 대장균군 및 황색포도상구균이 검출되었다. 2주간 손씻기 동영상 교육과 실습교육을 연속적으로 실시한 결과 손씻기 교육에 따른 손 위생상태는 개선되었다. 결과 손씻기 교육은 취학 전 어린이를 대상으로 손씻기 교육을 반복적으로 수행할 경우 더욱 효과적일 것으로 생각된다. 특히 미취학 아동의 경우 평생 습관을 확립시키는 중요한 시기이므로, 언제, 어디서 손을 씻어야 하는가에 대한 구체적인 교육이 필요할 것으로 생각된다.

This stduy was carried out to investigate the effect of concentration of PC12 and washing of sperm of sperm motility and acrosome reaction, and the effect of sperm incubated in mTALP solution containing PC12 112.5$\mu\textrm{g}$/ml on development of follicular oocytes matured in vitro. The results obtained were as follows. 1. When fresh sperm was once washed and then incubated in mTALP solution containing 0, 75, 112.5 and 225$\mu\textrm{g}$/ml PC12 for 15minutes, 225$\mu\textrm{g}$/ml showed significantly higher percent of acrosome reacted sperm than 0, 75, 112.5 and 225$\mu\textrm{g}$/ml. 2. When once or twice washed fresh sperm was cultured in mTALP containing 112.5$\mu\textrm{g}$/ml PC12 for 15minutes, no-washing showed significantly higher percent of motile sperm than that once- and twice-washing showed significantly higher percent of acrosome reacted seprm than no- and once-washing. 3. When sperm was cultrued in mTALP containing PC12, 112.5$\mu\textrm{g}$/ml for 15minutes and then was cocultured with bovine follicular oocytes matured in vitro, 11.2 to 22.4% of the oocytes were coleaved to more than 2cell stage.

Mechanical properties and hand evaluation of wool/acrylic(W/A) blend knits were conducted before and after repeated washing to get the optimum W/A blending ratio, which could help achieve the optimum mechanical and hand properties of the knits. The five test fabrics using the yarns with different W/A blending ratios($\%$), 100/0, 70/30, 50/50, 30/70, 0/100, were knitted. The fabrics were washed by a rotating drum type washing machine. Then, objective mechanical and hand properties were evaluated by KES-FB, Kawabata evalution system for fabric. The results are as follows: there was no change in the hand value of the knitted fabric with the W/A-blended yarn caused by the change in the blending ratio before washing. After washing, however, the increase of acrylic's blending rate caused the bending property to decrease proportionally, while the friction coefficient of the surface property increased. Furthermore, the study showed that W/A 50/50 possesses the most superior tensile property and shearing property, which could attain the optimum blending ratio. Similar results in hand value were derived in all the samples. After washing, however, the increase in acrylic's blending rate caused a proportional decrease in KOSHI and an increase in FUKURAMI. In addition, W/A 50/50 gained the biggest NUMERI value, again corresponding to the optimum blending ratio. Similar results in total hand value were derived in all the samples before washing. After washing, though, all the total hand values decreased, and, as the wool fabric's blending rate increased, the total hand values proportionally decreased further.

The most important practical feature that represents the performance of a washing machine is its ability to remove stains or soils from clothes. There are various tests to measure a washing machine's ability to remove stains or soils from clothes. The results of these tests are dependent upon the kind of soiled fabrics used. Moreover, these results may reflect some aspects of the effectiveness of a washing machine in cleaning clothes due to the paritcular compositions of chemicals which comprise soils in soiled fabrics and the particular conditions in which the results are evaluated. After selecting factors presumed to have a major effect on the cleaning ability of a washing machine and choosing most widely used soiled fabrics, we use experimetal statistics methods to screen real factors from them that influence the cleaning ability of a washing machine in a statistically significant manner for each soiled fabric. Using the least number of experimental rules required to extract the necessary information, we then proceed to present the study on the relations between the sets of selected factors and the soiled fabrics. We would then suggest which soiled fabrics is the best for evaluating the performance in cleaning clothes of a washing machine based on the above study.

This study investigated the detergency and functionality of laminating finished fabrics for outdoor wear based on repeated washing. Laminating finished fabrics were selected as the main fabrics for outdoor wear and used as test fabrics. The effects of outdoor exclusive detergent and normal neutral detergent were examined according to washing time, temperature, rpm and detergent concentration based on the use of a Terg-O-Tometer. Re-soiling of the test fabrics was measured by Florio-Mersereau. Permeability, water repellency, water resistance and absorbency were estimated to measure improvements and effects in regards to outdoor exclusive detergent in optimal washing conditions. The detergent effect of outdoor exclusive detergent was superior compared to normal neutral detergent. Re-soiling was lower with exclusive outdoor detergent than with normal neutral detergent. The measurement of functionality for laminating finished fabrics before and after washing indicated that functionality was decreased with repeated washing.

Generally, polyester microfiber has much greater dye uptake than that of regular ones. In spite of high dye up-take visual shade depth of dyed fabric decreases with smaller denier, which results in poor washing fastness of dyed fabric. In this study, in order to investigate the washing fastness, polyester microfiber fabric was dyed by using two type of disperse dyes and treated with 3 different reduction clearing methods. The reduction clearing methods in this study are normal alkaline reduction clearing, $N_2$ gas replacement method, and ultrasonic treatment during reduction clearing. The results were as followings ; The most important factors affecting the washing fastness of polyester artificial suede fabric were found to be the reduction clearing method, the chemical structure of used disperse dyes and the structure and denier of fibers. It was also obtained that the heat treatment of dyed fabric decreased the washing fastness due to the dye migration from inner phase to surface.

In cotton fabric sizing the domestic material is normally starch finds itself more frequent uses than the PVA size does. In this study we have examined the effects of ironing temperature and washing temperature on the removal of sized PVA by washing and have got following temperature on the removal of sized PVA by washing and have got following results: 1. the removal of PVA is related approximately to the reciprodal of the ironing temperature. 2. the higher the ironing temperature, the lower is the removal of PVA; and if the ironing temperature is higher than $140^{\circ}C$ the removal of PVA decreases abruptly even if the washing temperature were still high. 3. The most appropriate washing temperature should be at least $75^{\circ}C$when the ironing is carried out at 10$0^{\circ}C$ the same holds for $80^{\circ}C$to $120^{\circ}C$and $90^{\circ}C$to $120^{\circ}C$, respectively.

The washing effects on pretilt angle generation in a nematic liquid crystal (NLC), 4-n-pentyl-4’-cyanobiphenyl (5CB) on a rubbed polyimide (PI) surface with trifluoromethyl moiety have been successfully studied. The pretilt angle of 5CB is increased by the washing process on the rubbed PI surface. The surface tension on the rubbed PI surface increases with the rubbing strength RS and then saturated above RS=150 mm. The pretilt angle of 5CB for all washing processes on the rubbed PI surface decreases with the surface tension. We have found that the pretilt angle of 5CB on the rubbed PI surface may be attributed van der walls (VDW) dispersion interaction between the LC molecules and the polymer surfaces having trifluoromethyl moieties.

In order to investigate the detergency of the mixture of compact detergent and bleaching agent to fabric stained with a coffee and a red wine, respectively, and a japanese wet stained fabrics, to evaluation of detergency was studied under various washing conditions. In order to study the effect of alkaline agent addition on the detergency, the soda ash was added in the compact detergent system. The results are as follows : In a low temperature washing condition, the alkalinity of washing liquor effected more the removal of the composite stained fabrics than that of oilic stained fabrics. For the colored stained fabric such as red wine stained sample, the influence of the repeated washing treatment on the detergency was not significant factor. On the other hand, the influence of the repeated washing treatment for the coffee stained and japanese wet stained fabric on the detergency was gradually increased.
