Countries have different brassiere patterns, and this study produced and compared 3/4 brassiere patterns from different countries to determine the difference in patterns, and to investigate the stress distribution and shape of cross section while wearing brassieres using 3D virtual fitting system. Despite the growing interest in underwear, there is a lack of related books and research on brassiere patterns, which causes the difference in sizes and pattern drafting methods by countries. Thus, research on this is needed. 3D virtual fitting system has been introduced to compare patterns, thereby improving visible effects and reducing the loss in cost caused by underwear pattern fitting test. According to the result of pattern analysis, The Secoli type exhibited the least breast cover rate (14.9 cm), while the largest cover rate was shown in Christina and ESMOD types (17.7 cm). It is believed that the difference in pattern drafting causes the difference in the total length of a brassiere. Furthermore, the Secoli, Moda Burgo, and ESMOD brassieres drafted from basic bodice pattern were found to be longer than the Christina and Han Sunmi brassieres attained from direct pattern drafting. Moreover, the darts' volume of upper and lower cups in Christina and Han Sunmi types was similar in shape. The shapes of cradle drafted from basic bodice pattern were a straight line, while those from direct drafting formed a curved shape. In fitting multiple cross sections, the Secoli, Moda Burgo, and ESMOD brassieres had gaps between the brassieres and the body. Among these, the largest number of gaps was observed in the ESMOD type pattern. This study aimed at performing comparative analysis of various brassieres' pattern drafting types as a basic research for developing a brassiere pattern drafting type.

Recently, strong interest in the well-being and healthy food trends lead a spreading of rice processing products such as rice noodles, rice breads, and rice cakes. However, most of rice varieties developed in Korea showed very limited processing properties in processing of noodles compare to that of wheat flour. Moreover, low competitiveness as a raw processing materials due to high price give poor evaluations for rice noodles processing. To cope those barriers, 'Saemimyeon' a Tongil type high yielding variety with a high amylose contents was developed in RDA. 'Saemimyeon' showed about 10~32 % of increase in yield as 7.08MT/ha and 26.7% of high amylose contents together with easy grinding property of 65.7% of high chalkiness ratio. The both of milled as well as brown rice of 'Saemimyeon' were well fit for processing properties in rice pasta where the contents of rice flour for rice pasta was 99% (1% of Tapioka starch was intermixed in to the rice flour). A spaghetti type for wet noodles and macaroni type for dry noodles were developed, respectively. Each of pasta were showed relatively more or less an equal quality and panel test compare to that of durum wheat pasta products. Finally, rice pasta products could suggest an alternative idea for a new rice processing items where rice noodles market was stagnant.

Nowadays, We have had a growing interest in high-speed vessels' because it is very important to save time and cost in marine transportation. The development of hull form for high-speed vessels is high priority to secure the competitive power for the transportation of cargos. Therefore, the demand of the high-speed vessels is gradually increased, but the conventional hull forms are limited by rapidly increasing resistance upon the increase of ship speed in high-speed region. Therefore, new concepts for the hull form of high-speed vessels have been requested. One of the derived hull forms for that demand is the hull form of trimaran type. Trimaran has a very slender main hull as compared with conventional single hull so that is reduced in wave resistance. The slender main hull has the undesirable characteristics of stability, but two side hulls make up for the week points in the stability. That is, trimaran is able to have desirable performances for the resistance and stability. In this paper, for the design of 200TEU class container vessel with trimaran type, which will be cruised in Yellow-Sea region, firstly a preliminary hull is designed, and the model test is carried out with the variation of side hull position. From the experience of the preliminary hull form design, an improved hull form for the 200TEU container are designed, and the model tests are carried out. Also, a numerical computation technique is adopted for the simulation of flow phenomena around the designed hull forms. The final hull form is compared with existing ships for the resistance performance from the computation with computer and ship model tests.

The purpose of this study was to investigate consumer's behaviors on the laundering of baby's clothing according to washing machine types. The subjects were 255 consumers with babies(0-2 years) in Korea. The data were collected with a self-administered questionnaire and analyzed by Chi-square test and multiple response analysis, and SPSS 12.0 statistics package was used. Consumers were separated into two groups according to washing machine types with general pulsator type and drum-type. Consumer's behaviors between general pulsator type group and drum-type group of washing machines were also examined. The results of this study were as follows. In the consumer satisfaction for washing machine, mostly drum-type group of consumers were satisfied with their washing machines. As the reasons of washing machine's dissatisfaction, noise, washing time and low washing efficiency were high in the pulsator type group, and washing time, noise and high price in the drum-type washing machine group. The consumers concerned about separation of clothing and laundering label while they washed laundry by washing machine. However, they didn't separate clothing because the small volume of laundry and a long washing time. The most interest and required thing of consumers was complete rinsing without any detergents used in washing as well as the removal of soils for baby's clothing regardless of two washing machine types. And they complained food soils like milk and mother's milk etc. were not completely removed by washing machine. As a whole the washing frequency of baby's laundry was once per a day and the rinsing also more than three times per a laundry. Most of the consumers used a private detergents for baby's clothing(detergents for baby's clothing only), and preferred to the high or boiled temperature washing as a desirable baby's laundering. There were significant differences between general pulsator type group and drum-type group of washing machines on the laundering of baby's clothing in this study.

PURPOSE. The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. This study compared the bond strength of porcelain to millingable palladium-silver (Pd-Ag) alloy, with that of 3 conventionally used metal-ceramic alloys. MATERIALS AND METHODS. Four types of metal-ceramic alloys, castable nonprecious nickel-chrome alloy, castable precious metal alloys containing 83% and 32% of gold, and millingable Pd-Ag alloy were used to make metal specimens (n=40). And porcelain was applied on the center area of metal specimen. Three-point bending test was performed with universal testing machine. The bond strength data were analyzed with a one-way ANOVA and post hoc Scheffe's tests (${\alpha}=.05$). RESULTS. The 3-point bending test showed the strongest ($40.42{\pm}5.72$ MPa) metal-ceramic bond in the nonprecious Ni-Cr alloy, followed by millingable Pd-Ag alloy ($37.71{\pm}2.46$ MPa), precious metal alloy containing 83% of gold ($35.89{\pm}1.93$ MPa), and precious metal alloy containing 32% of gold ($34.59{\pm}2.63$ MPa). Nonprecious Ni-Cr alloy and precious metal alloy containing 32% of gold showed significant difference (P<.05). CONCLUSION. The type of metal-ceramic alloys affects the bond strength of porcelain. Every metal-ceramic alloy used in this study showed clinically applicable bond strength with porcelain (25 MPa).

이 연구의 목적은 중$.$고등학교 기술$.$가정과 교사의 수행평가에 대한 관심도 및 실행수준, 실행실태, 지원정도를 분석하여 수행평가의 보다 효과적인 실행을 위한 지원 체제를 수립하기 위한 기초자료를 제공하는 데 있다. 연구 자료는 텍사스대학의 교사 교육을 위한 연구 개발 센터에서 Hall. Hord등이 개발한 관심에 기초한 혁신채택 모형을 연구 도구로 하여 경기도에 소재한 95개 중$.$고등학교 기술$.$가정과 교사를 대상으로 우편을 통한 설문지로 수집하였으며, 157부를 최종 분석에 사용하였다. 자료는 SPSS/WIN 프로그램을 이용하여 평균, 표준편차, 백분율, t-test, ANOVA, 카이검증 분석을 실시하였다. 이 연구를 통해 밝혀진 결과를 요약하면 다음과 같다. 첫째, 기술$.$가정과 교사들의 수행평가에 대한 관심도는 대부분이 실행 초기 상태를 나타내고 있었던 반면에, 실행수준은 4. 5단계에 많은 빈도를 보여 교사들은 자신의 수행평가 실행수준을 관심도가 시사하는 것보다 더 높게 평가하는 것으로서 이는 학교에서 본인의 관심도와는 관계없이 업무상 평가와 관련된 지침을 만들고 평가에 대한 근거 자료를 남겨야 하는 교육 현장의 현실과도 관련이 있는 것으로 보인다. 둘째. 수행평가 실행실태는, 실행수준이 높은 교사일수록 수행평가 본래의 취지에 부합된 실행실태를 보여주었으며, 수행평가 시행을 위한 지원에 대한 기술$.$가정과 교사들의 인식 정도를 조사 분석한 결과는 전반적인 평균점수가 7점 만점에 3점 이하로 나타나 지원의 정도가 미비한 것으로 나타났으며, 관심유형 및 실행 수준별 분석에서도 단계별 지원이 전반적으로 이루어지지 못하고 있음을 알 수 있다. 이상과 같이 중$.$고등학교 기술$.$가정과 교사들의 수행평가에 대한 관심도와 실행수준. 실행형태를 알아본 결과 교사들의 개인적 특성에 따라 관심유형과 실행수준에서 많은 차이점이 있음을 알 수 있었으며, 그 실행형태 또한 다양하게 나타나고 있으나 수행평가에 대한 지원 정도를 분석한 결과는 관심유형별로 차별화 된 지원이 전혀 이루어지지 못하고 있는 실정이므로 수행평가의 효과를 극대화하기 위해서는 교사 자신이 수행평가에 대해 지속적인 관심을 가져야 하고, 학교당국. 교육행정가. 교육전문가 등의 변화 지원자는 수행평가 실행과정 동안 발생하는 문제들을 해결할 수 있도록 개별화된 지원을 아끼지 않아야 한다. 따라서 교사들의 관심유형과 실행수준에 따라 수행평가에 대한 지원을 달리함으로써 교사들의 관심도와 실행수준을 향상시켜야 할 것이며 보다 효과적인 수행평가가 실시되도록 해야 할 것이다.

This study aims to investigate the impacts of marketing motive (public- vs. firm-interest) and ad appeal (soft- vs. hard-sell) types on consumers' ad attitudes and behavioral intention in hotels' green advertising. From 711 US respondents, a multivariate analysis of covariance (MANCOVA) was employed to test main effects of marketing motive and ad appeal types on ad recipients' affective and cognitive ad attitudes, while controlling their environmental consciousness. Further, the study conducted a multiple regressions analysis to examine the influence of ad attitudes on respondents' intention to visit the hotel. The study found that a public-serving claim can yield more positive affective ad attitude than a firm-interested claim, regardless of ad image type (soft- or hard-sell image). The result also revealed that a soft-sell ad image can elicit more positive affective ad attitude than a hard-sell one. On the other hand, the study showed that consumers' affective and cognitive ad attitudes are significant predictors of behavioral intention (i.e., visit intention). The study provided theoretical and managerial implications for hospitality researchers and hotel marketers to effectively design hotels' green advertising to ultimately increase consumers' visit intention.
