This research focused on determining the brassiere preference index and wearing status of chinese ladies in their 20's living in the Shanghai region of China, to help Korean lingerie companies in their development of bras to successfully advance into the Chinese lingerie market. The main research tool of this research was various different surveys, and the results of the surveys were evaluated using the SPSS 12.0 for Window program. The results of the survey can be summarized as: 1) consciousness and satisfaction level of the body. The satisfaction level of the brest was proportionate to the size of the brassiere, thus, people showed higher level of satisfaction for cone-shaped, semi-circular shaped, prominent-shaped(exposing), lifted-shaped brest over flat-shaped brest. Concerning the relationship between the shape of the brest and the age of the customers, people under 22 years of age preferred flat-shaped, and those between 23-24 years of age preferring exposing and lifted brest, thus as females mature and get older, the size of their brest increases, thus having preference on more circular and lifted-shaped brest and bras. 2) Status of bra wearing in China When we look at the size of the bra in relation to the shape of the brest, those classified as having 'flat-shaped' brest showed a high proportion of A-cups, ranging from 75A, 70A and 80A, where as those of 'cone-shaped' brest represented high ration of B-cups, ranging from 75B, 75A and 80B. Majority of those classified as having 'semi-circular shaped' and 'prominent-shaped(exposing)' brest showed a high ration in the size 80 range. And vast majority of those classified into the 'lifted-shaped' brest group, were reported of having C-cup size bras. 3) Status of Bra Purchasing As people mature, the main reason behind choosing a bra was the actual design of the bra, where they emphasized the importance of aesthetic values. People classified as having 'flat-shaped' and 'cone-shaped' brest emphasized the importance of design and beauty, while those having 'semi-circular shaped,' 'prominent-shaped(exposing),' and 'liftedshaped' brest groups emphasized the importance of hygiene and the material(fabric) of the bra. This shows that when people have relatively smaller brest, they emphasize the importance of external appearance whereas when the size of the brest increases, they pay more attention to the function of the bra rather than the external appearance.

The flow and heat transfer characteristics for three-dimensional mixed convection flows in a radiator flat tube with U--shaped grooves are analyzed numerically. The flow and temperature fields are calculated by using the modified SIMPLE algorithm for irregular geometry. One tube specification among the various flat tube exchangers is recommended by considering the heat transfer and pressure drop. The effects of variation of coolant flow conditions and external air conditions on the flow and the thermal characteristics for the selected tube are investigated. the results show that inlet velocity of coolant flow is the very important factor in heat transfer and pressure drop, and top side is better position than the others as fin cleave to tube.

A finite element program is developed to analyze the flow phenomena in SMC compression molding as a viscoplastic model. The calculation of temperature distribution is also carried out by uncoupling the thermal analysis from the flow analysis. SMC molding processes with a flat plate substructure and the one with a T-shaped rib are considered in numerical simulation. The numerical results provide deformed shapes, temperature distribution in a SMC charge, and the forming load. The simulation of compression molding of a flat plate with a T-shaped rib requires a remeshing technique for the whole process.

다호리 유적에서 출토된 판상칠기에 대하여 수종 및 칠 도막, 금속장식 분석을 실시하였다. 판상칠기에 사용된 수종은 소나무류로 식별되었고 칠 도막의 현미경 관찰 결과, 총 5회의 칠을 했으며 칠 전체 두께는 약 100 ㎛이다. 적외선 분광 분석을 통해 정제칠과 비교하여 옻칠임을 확인하였다. 원형의 금속장식에 대한 성분 분석 결과는 주석과 납의 이원계 합금으로 백랍(白蠟, Pewter)이라 불리는, 주석을 주체로 하는 합금으로 확인되었다. 더불어 지금까지 조사된 다호리 유적 출토 유물의 수종이 활엽수재였던 것에 반해 판상칠기의 목재는 침엽수재인 소나무류로 밝혀졌다.

Low cycle fatigue tests on the hydrogenated welding seam of Zr-Sn-Nb alloy at room temperature and 360 ℃ had been carried out by using the funnel-shaped flat specimens. The relationships between nominal stress & strain directly measured across the funnel and local stress & strain at the root of the funnel are given by considering cyclic plasticity correction. The results show that the fatigue resistance of welding seam at room temperature is only slightly better than that at 360 ℃. Probabilistic fatigue life curves are obtained by using a two-parameter power function.

본 논문에서는 a-Si(amorphous-Silicon) TFT(Thin Film Transistor) LCD (Liquid Crystal Display)상에서 다중 비디오 신호원을 디스플레이 할 수 있는 $\Delta$-shaped 보간 방식올 제안하였다. 제안한 방식은 단순한 회로만으로 구현이 가능하므로 펼드 메모리와 같은 비용의 증가 없이도 평판 디스플레이(FPD : Flat Panel D Display) 시스템에 적용될 수 있다. 제안한 방식과 기존의 방식을 비교하기 위하여 PSNR(Peak Signal Noise Ratio)을 도입하였으며, 컴퓨터 시율레이션상의 처리결과를 에지 특성에 초점을 두어 평가하였다. 컴퓨터 시율레이션을 통해 에지와 이미지의 국부특정의 관점에서 볼 때, 제안한 방식이 기존의 방식보다 우수함을 확인하였다. 마지막으로 제안한 방식의 특성과 트레이드 오프(trade-off)에 대하여 논하였다.

The peanut-shaped cloth diaper has cut uncomfortable crotch region off the square-shaped cloth diaper into a peanut-shape, and finished the edge by bias with multi-layers of fabric. This study has the purpose on providing the basic data for designing the peanut-shaped cloth diaper. For this purpose, the peanut-shaped cloth diapers on market were collected and analyzed by their shape and size, and also the patterns and differences in making were compared. 26 products from 17 brands were collected as samples. The analysis factors are the shape and size of the peanut-shaped cloth diaper, and characteristics and patterns in making. Among the samples, only 3 diapers were straight-shaped; the rest of them were peanut-shaped. The size difference between the big and small peanut-shaped cloth diapers was very large; the total length of the small one was 36.5cm-39cm which was very common, and the total length of the big one was more than 44cm. All diapers had longer width in the back than the front. The width of the front and back was different for each sample, therefore, it seemed to have some difficulties to set the standard. The peanut-shaped cloth diaper had different make-up depending on its characteristics including. absorbance, washing and drying. It was usually made by cotton woven of diamond jacquard or knit, and finished the edge by woven bias or knit bias. The peanut-shaped cloth diapers were various including a sheet of diaper, two sheets of diapers fixed with velcro, three sheets of diapers, and etc. For the patterns of the diapers, only two samples out of all had three dimensional shape, and the rest were produced using flat shape. There were no distinction between the diapers of girls and boys. Therefore, it is necessary to make the product based on scientific data about the peanut-shaped cloth diaper.

Using the extensive datasets, I analyze the effect of tick size changes on the intraday patterns of spread and depth. I show that intraday variations in spread (depth) are greater (smaller) with smaller tick size during the early hour of trading and become smaller (larger) during the last hour of trading. And the standardized spreads (depths) are quoted at the lower (higher) levels as the tick size becomes smaller. I also find that U-shaped intraday spread pattern changes to the reverse flat S-shape while inverted U-shaped depth pattern does to the flat S-shape.

An analytic approach has been employed to study condensate film thickness distribution inside cave-shaped cavity of a flat plate heat pipe. The results indicate that the condensate film thickness largely depends on mass flow rate and local velocity of condensate. The increasing rate of condensate film for circular region reveals about 50% higher value than that of vertical region. The physical properties of working fluid affect significantly the condensate film thickness, such as the condensate film thickness for the case of FC-40 are 5 times larger than that of water. In comparison with condensation on a vertical wall, the average heat transfer coefficient in the cave-shaped cavity presented 10∼15% lower values due to the fact that the average film thickness formed inside the cave-shaped cavity was larger than that of the vertical wall with an equivalent flow length. A correlation formula which is based on the condensate film analysis for the cave-shaped cavity to predict average heat transfer coefficient is presented. Also, the critical minimum fill charge ratio of working fluid based on condensate film analysis has been predicted, and the minimum fill charge ratios for FC-40 and water are about Ψ$\_$crit/=3∼7%, Ψ$\_$crit/=0.5∼1.3% respectively, in the range of heat flux q"=5∼90kW/㎡.
