본 논문에서는 세탁기용 DD모터로 사용되고 있는 BLDC를 대신하여 외전형 Switched Reluctance Motor (SRM) 타입으로 세탁기의 부하에 따라 저속/고토크인 세탁모드, 고속/저토크인 탈수모드의 특징에 만족시키는 전동기를 설계한다. 이와 같은 특징을 고려하여 외전형 SRM의 극 조합을 12/8, 18/12, 30/20, 36/24에 대해 설계하고 FEM을 통해서 특성을 해석한다. 이 중 세탁기용 전동기에 알맞은 구조를 선정하고자한다.

This study analyzed satisfaction with and washing of newborn clothing (especially the innerwear washing behaviors) which are considered to be the most basic items among newborn clothing.The survey was conducted on mothers with children under 24 months old. Using an average of 6.7 innerwear items that were changed average 2.3 times a day with baby formula and breast milk representing the main contaminants. When washing clothes for a newborn, respondents were mainly concerned with: rinsing residual detergent, removing stains and contaminants, and sterilization and disinfection. Items were washed by a laundry label to prevent clothes damage. A baby-friendly or environmentally-friendly detergent was used to wash before being worn after purchase was separated and washed in various washing courses of the washing machine every day, boiled, rinsed an average 3.6 times, and dried mainly in the sun. Environmentally friendly cotton (59.5%) and organic cotton (41.6%) products were mainly used; however, items were washed separately from regular laundry. Respondents were satisfied with methods of washing. Consumers are concerned about washing because they think that washing affects a newborn's health. Therefore, it is necessary to provide consumers with appropriate information on washing and establish regulations for the use of harmful substances in newborn clothing and detergents.

These studies are carried out to improve silk availability for anticrease by useing methacrylate monomer polymerization method with in silk fiber. For this purpose, degree of anticrease, stiffness and shrinkage of various silk fabrics, included finish or not, after repeat of washings and polyster fabric was compared as standard. The adopted samples are ; 1. Polyester, Georgette, Woven density…90cm-85g/m 2. Silk, Twill, Degumed, Light, Woven density…90cm-90g/m 3. Silk, Twill, Degumed, Heavy, Woven density…90cm-200g/m 4. Silk, Stain, Degumed, Light, Woven density…90cm-90g/m The reached results are as followings. 1. The results of improving on anticrease by the finished method were about ten per cent increase against their original samples. 2. The light density silks showed satisfactory improve for anticrease, but the heavy one remained as rather poor condition. 3. The results for degree of textile stiffness were investigated to make sure reserve their textile feeling and observed to be good condition upon the finish work. 4. Textile shrinkage after the repeat of soap wash was investigated on indivisual test sample and silk fabrics showed more shrinkage than polyester which it seemed to be tentering shrinkage druning their general finishing processes. 5. The investigation showed that anticrease, stiffness and shrinkage of the sample textile were more or less deteriorated regardless silk or polyester by the repeat of washings. These matters are considered that such results were obtained because of the fiber fatigue nature. 6. The report reached that silk textiles should be used by dry cleaning methed after finish of any resin finish to reserve their improved anticrease nature.

무선 전자상거래(M-Commerce)는 이동 통신 네트워크 기술과 무선 단말기를 기반으로 하여 언제 어디서나 필요한 시점에서 행할 수 있는 상거래를 의미하며 이때, 전자지불 방식의 하나인 전자화폐는 실물화폐와 유사한 성질을 만족해야 한다. 본 논문에서는 이산대수문제에 기반한 메타-메시지 복원과 은닉 서명 기법을 이용하여 전자화폐가 이중사용, 돈 세탁 그리고 불법 무기 구매 둥 부정한 수단으로 악용되었을 때 신뢰센터가 사용자의 익명성을 제어하고 지불 금액을 다시 복원할 수 있는 알고리즘을 제안한다.

The purpose of this study was to investigate i) the current state of washing knowledge and washing habits ii) the effect of washing behaviors on washing satisfaction. A survey questionnaire was developed and implemented to married women in their 30's or 40's. A total of 210 responses were analyzed by frequency analysis, t-test and ANOVA with PASW18.0. The results are as follows. First, the ways in which women do the laundry was analyzed. Married women in their 30s and 40s usually do the laundry at home and are familiar with washing symbols and do not rely on common sense. Most of them like to rely on the washing machine guidelines for detergent concentration and use the right amount for environmental protection. They also adjust the washing machine setting effectively considering laundry time, water temperature and care label. Second, the groups divided by demographic variables showed meaningful results about washing knowledge. Particularly, there is no significant difference on washing knowledge between housewives and career women. Third, the groups divided by the levels of washing habits showed suggestive results about washing satisfaction. The groups who have correct washing habits generally a indicated high degree of washing satisfaction. Finally, marketing implications for the businesses of laundry, laundromat and the manufacturers of washing machine are suggested.

This study investigates the actual wearing conditions of functional mountaineering garments in Korea and provides suggestions on the development of more effective functional mountaineering garments through the examination of consumer data. This survey was based on 107 respondents who enjoy mountaineering and was composed of 5 sections consisting of personal information, purchasing habits, essential features for mountaineering garments, satisfaction levels based on features and functions, and additional comments on the improvement of mountaineering garments. Respondents said that essential features for mountaineering garments are quick absorbing/drying, insulation, water and wind proof, and elasticity. These properties become more effective when users wear mountaineering garments in layers. They want lower prices and easy to wash garments. Therefore, it is necessary to consider not only the main functions, but also the needs of consumers for easy washing and price.

In this study, what is motivation factors through academic study about whether to choose a career for chef and analysis career choice motives and IPA between importance and satisfaction and motivation was to analyze the impact of factors affecting satisfaction. The impact on job satisfaction according to the chef choose the real motivation, self-centered, values, etc., but having a significant impact on satisfaction stable did not have any effect on satisfaction. Therefore, the management runs the company makes employees motivate to engage in promoting stability through increased opportunities to employees, the ability to demonstrate opportunities, compensation, career development, work environment improvement. In addition, unlike the restaurant operated by individually casinos and luxury hotels apply overtime, laundry service, employee cafeteria, night shift allowances, operated by the Labor Standards Act such work 40 hours, but the non-corporate individual restaurant or newly opened hotels that still don't have it showed the low importance for welfare benefits, and expected to have a high turnover rate.

This study investigated underwear consumption behavior of women, who were 20∼59 years old and resided in Incheon during 2002 summer. 372 women completed questionnaires, and data were analyzed using factor analyses, t-test, ANOVA, $\chi$$^2$-analyses. They usually purchased underwear considering comfort and economic factor at a discount store. They wore sleeveless T-shirts, but they didn't wear underpants except panties highly all the year round. Higher rate of them wore pantyhose instead of underpants during autumn, winter and spring. They demanded unstitching of stitches and lengthened sleeves in most of the groups. And older and lowly educated women group wanted widen armhole of upper underwear, and tighten waistband of panties. They generally washed in washing machine using cold water. Besides they added oxygen bleach and softner during wash and final rinse. Older than 20's boil their underwear frequently. The women in a group of boiling commonly answered the looseness of waistband. It is recommended not to boil but to soak with bleach added warm water for improving the whiteness and durability of underwear. For a treatment with higher temperature deprives the elasticity of spandex.
