"Mixed construction of platform" means the platform which was constructed by mixing heterogeneous materials such as roof tiles or bricks with divided stone of trimmed stone. This kind of construction technique was not known or found from the building sites of Goguryo or Silla so far and therefore it used to be understood as a unique platform construction technique or the product of technology and creativeness of Baikje's craftsman. The mixed construction of platform of Baikje came to position itself as one of the patterns of platform mainly used over Sabi period and we found the pattern from the sites including Imryugak site in Gongju, temple for royal tomb in Gwanbuk-ri, Wangheungsa Temple site, building site in Keumseong Mountain, Ohapsa Temple site in Byryeong. From the fact that they used a variety of materials which they could easily get around them such as roof tiles or bricks in addition to stones for the construction of platforms, we can see the feasibility and decoration characteristics of their material supply at that time. On the other hand, this mixed construction of platform was not popular in Goguryo and Silla, the major reason for which is judged to be non-existence of platforms to construct using bricks or roof tiles which could be constructed together with platform using divided stones. This is supported by the results of excavation of Hwangryongsa Temple site, Bunhwangsa Temple site, Heungryunsa Temple site of Silla which gave us comparatively abundant excavation data, and Jeongreungsa Temple site, Cheongamsa Temple site, Toseongrisa Temple site and building site in Daeseong Mountain castle and Anhak Palace site of Goguryo. For further progressive study on the mixed construction of platform of Baikje in the future, we will have to review more on the social background and technical background with the linkage with archeology and architecture at that time which led to the creation of such platform.

In order to reflect traditional elements in modern design, designers should be able to creatively apply elements of traditional Chinese clothing. To understand this, a deep understanding of and insights into the traditional clothing culture are required. In this study, the characteristics of traditional Chinese women's clothing from the Wei, Jin, and Northern and Southern Dynasties of China to the Qing Dynasty were analyzed by dividing them into silhouette, color, pattern, materials, and detail. The characteristics of the silhouette were classified into A, H, X, and O types, of which types A and H were the most common. As for the color characteristics, there are relatively many five cardinal colors, and for the contrast of colors complementary colors were mainly used. As the for pattern characteristics, real patterns, animal patterns, character patterns, geometric patterns, and mixed patterns were used. Four types of materials were mainly used: silk, hemp, cotton, and wool. The detail characteristics were also anlyzed by classifying them into collar, sleeve, neckband, and gusset. Based on the results of this analysis, a satisfaction survey was conducted on the design of modern Chinese women's clothing. The result of satisfaction with design elements showed that the images of vest and suit were most preferred, H and X silhouettes, and yellow and white were the most preferred. Geometric and plant patterns were preferred, as were silk and acetate materials. Based on the result of chi-square analysis of design element preferences according to the characteristics of the subject, there was no difference according to occupation, residential area, or income, and there were differences in silhouette, color, materials, and detail according to age.

The effects of a mixing vane on air-water mixed flow have been experimentally studied in this work, to investigate the basic mechanisms that the mixing vane affects critical heat flux (CHF). Experiment was performed for various flow rates focusing on bubbly flow and annular flow patterns. Acrylic tube (1.7m long, 11 mm I.D.) and the split vane type mixing vane were used, and ring-type conductance probes were used to measure the liquid film thickness in annular flow. Experimental results show that, (a) bubbly-to slug flow transition and churn-to-annular flow transition occur respectively near the mixing vane compared to the tests without mixing vane, (b) in bubbly flow region, the mixing vane breaks the bubbles into smaller ones and forwards bubbles to the center region of the tube by the centrifugal force, (c) the liquid film thickness in annular flow is decreased near the mixing vane for mass fluxes.

For the improvement of the pump characteristics in the partial capacity range, it must be verified that the influence of the impeller design factor on the internal flows and the influence of the impeller internal flows on the pump characteristics. In this paper, in order to understand the influence of outlet angles on flow conditions and characteristics of a mixed flow pump, experiments were carried out for four kinds of impeller, which have the same inlet angle distributions and meridional section shapes. Results shown that separation and stall in the partial capacity range were enlarged by the outlet angles. The relationship between the separation and the stall at the impeller and the discharge flow conditions were clarified.

As the increasing integrity of VLSI, the BIST(Built-In Self Test) is used as an effective method to test chips. Generally the pseudo-random test pattern generation is used for BIST. But it requires too many test patterns when there exist random resistant faults. Therefore we propose a mixed test scheme which applies to the circuit under test, a deterministic test sequence followed by a pseudo-random one. This scheme allows the maximum fault coverage detection to be achieved, furthermore the silicon area overhead of the mixed hardware generator can be reduced.

$(SrBi_2Nb_2O_9)_{0.5}-(Bi_3TiNbO_9)_{0.5}$ ceramics were fabricated by the mixed-oxide method, and the structural and electrical properties with variation of ball-milling time were investigated. All SBN-BTN specimens showed the typical polycrystalline X-ray diffraction patterns without the presence of the second phase. The SBN-BTN specimen sintered at $1200^{\circ}C$ and ball-milled for 168h showed the average grain size of $16{\mu}m$. The dielectric constant and dielectric loss of the SBN-BTN specimen sintered at $1150^{\circ}C$ and ball-mill for 72h were 225, 0.4% at 1KHz, respectively.

To alleviate NOx emission, a variety of approaches has been applied. In marine diesels, the application of SCR systems has been considered an effective exhaust aftertreatment method for NOx emission control. Most current SCR systems use a various catalyst for the reaction of ammonia with NOx to form nitrogen and water. In theory, it is possible to achieve 100% NOx if the NH3-to-NOx ratio is 1:1. However, the reaction has a limited non-uniformity of the exhaust gas flow and ammonia concentration distribution. Therefore it is necessary to investigate the optimum flow conditions. In order to achieve uniform flow at monolith front face, we are equipped with a various mixed device. In this paper, it is presented that the mixed devices play an important role improvement of flow patterns and particle distributions of NH3 by numerical simulation.

Theoretical fringe patterns were calculated and regenerated by using power series type Williams equations and coefficients estimated from the photoelastic data. Results of calculated values were evaluated by comparing experimental data points with the regenerated theoretical fringe loops. Statistical accuracy evaluation between regenerated fringe values and experimental ones showed that standard deviation was minimum and correlation coefficient was maximum when the first four terms of Wiliams equations were used.

The study of mixed convection in a room with heated bottom surface and various partitions has been numerically investigated using a finite volume method. The parameters studied here are, 50$\overline{Nu}=\overline{Nu_n}{\cdot}(1+c(Re/Gr^{1/2})^d)$, where $\overline{Nu_n}$ corresponds to pure natural convextion.
