대표적인 비탈면 배수공법인 수평배수공은 비탈면 내 간극수압을 감소시키기 위해 국내외에서 다수 활용하고 있다. 이에 따라 다양한 연구들이 선행되어 왔으나, 수평배수공의 수량을 산정하기 위한 명확한 설계기준이 없어 획일적으로 시공되고 있다. 따라서 본 논문에서는 다양한 수평배수공의 배수성능과 영향인자에 대한 메커니즘을 규명하고자 현장토를 이용하여 모형토조실험을 수행하였다. 또한, 배수재 형상이나 크기에 따른 배수성능을 비교하고자 입도분포가 다른 시료에서의 유출량 결과를 비교 및 검토하였다. 정상류 상태에서 배수실험을 확인하기 위해 유출량을 측정한 결과, 모든 시료에서 최소 3분에서 최대 15분 뒤 일정한 속도로 배수되는 것을 확인하였다. 조립질 지반에서 단일 시간당 유출되는 양(단위 유출량)으로 비교한 경우, 배수재 형상과 크기에 따른 배수효과가 상이하여 배수성능에 영향을 미치는 것을 확인하였다. 향후 세립질 지반에서의 배수 성능실험과 수량을 결정하기 위한 기초자료로 충분히 활용될 수 있을 것으로 기대된다.

Painting style has mostly affected the creativity of fashion design. The formative of shape and color shown in each painting has close relationship with fashion design. With use of ideas of artists, the fashion designers have made clothes having novel and creative designs. Since the society becomes more diverse and complex and the men's life style has been changed, the contemporary man expresses himself by fashion and he needs the fashion having emotionality and individuality. In accordance with the contemporary customer's needs seeking for the individuality of his own, the development of much more originative and differentiated cloth design by adapting arts to fashion designs is needed. In this study, therefore, the paintings of Paul Klee, who is the representative contemporary artist, have been used as man's dress shirts and jean pants. The paintings have been printed by CAD system. As a result of the adaptation of Paul Klee's painting to men's dress shirts and jean pants, a modern and creative design is developed. And also a new and differentiated design is achieved freely with use of the CAD system by changing the design, textile, and color ways.

Indonesia is archipelago country and plural society which consist of diverse ethnic groups. This study select Java island and Java houses as a representative housing of Indonesia. The aim of this study is to present a comprehensive overview of traditional houses of Java in Indonesia by examining pre-existing literature. First, the Java House as a microcosm of the universe that shows universal and religious aspects. Furthermore, each building contains spiritual symbolism. These ideological aspects select the location and layout of the towns, villages and buildings, which create an order to the interior space. The space structure of Java housing is characterized by strong juxtaposition between east/west, front/back, public/private, male/female, and open space/ closed space. There is also a hierarchy of space, which were applied in floor level, height of space and lightness. The structure of the roof shows the best formativeness. Depending on the shape of the roof, the function of the building is shown, and also it represents the social rank and religious respect. Joglo's unique formativeness is an icon of the Java architect.

Plane detection is very important information for mission-critical of robot in 3D environment. A representative method of plane detection is Hough-transformation. Hough-transformation is robust to noise and makes the accurate plane detection possible. But it demands excessive memory and takes too much processing time. Iterative randomized Hough-transformation has been proposed to overcome these shortcomings. This method doesn't vote all data. It votes only one value of the randomly selected data into the Hough parameter space. This value calculated the value of the parameter of the shape that we want to extract. In Hough parameters space, it is possible to detect accurate plane through detection of repetitive maximum value. A common problem in these methods is that it requires too much computational cost and large number of memory space to find the distribution of mixed multiple planes in parameter space. In this paper, we detect multiple planes only via data sampling using Self Organizing Map method. It does not use conventional methods that include transforming to Hough parameter space, voting and repetitive plane extraction. And it improves the reliability of plane detection through division area searching and planarity evaluation. The proposed method is more accurate and faster than the conventional methods which is demonstrated the experiments in various conditions.

Effects of injection conditions on a pintle injector which is proper to recent liquid rocket engines requiring low cost, low weight, high efficiency and reusability were studied. The pintle injector with a typical moving pintle was used for atmospheric experiment using water and air. Injection pressures of water were considered 0.5 and 1.0 bar, 0.1 to 1.0 bar for injection pressures of air and 0.2 to 1.0 mm for pintle opening distance. Sauter mean diameters (SMD) of spray was measured at 50 mm distance from a pintle tip and SMD was treated as a representative parameter in this study. As a result, because of shape characteristics of the pintle injector, there was a transient region between the pintle opening distances of 0.6 and 0.7 mm and this region affected to mass flow rates and SMDs. Also, Reynolds numbers for gas, Weber numbers and momentum ratios were adopted as major non-dimensional paramters and the momentum ratio has strong correlation with SMD.

The purpose of this study is to suggest the possibility of futurism as original design pursuing newness in approaching 21C by studying how futurism having a great effect on fashion as innovatory ideology in early 20C did became paradigm in 20C fashion and the common peculiarity of the dress and its ornaments in this time before 21C. The Space Age Fashion and Techno-Cyber Fashion are representative futurism fashion of 20C. The common inner inclination in both Space Age Fashion and Techno-Cyber fashion are ; First, a future-oriented character. Second, a surrealism character, Third, an anti-cultural character. The greatest peculiarity in the common outer shape in both Space Age Fashion and Techno-Cyber Fashion is material. First, a innovatory choice. Second, an active motion. Third, a diverse effects. Future dress and its ornaments of 21C may be changed greatly by the development of technique, and this fact supports the forecast that the change of paradigm resulted from the development of science may have an effect on future dress and its ornaments as well as modern one. The paradigm change of futurism fashion would be continued, and its influence would work as main source shaping the form of design in 21C.

This work reports a set of approximate analytical solutions describing the initial transient process of close-contact melting between a rectangular parallelepiped solid and a flat plate on which either constant temperature or constant heat flux is imposed. Not only relative motion of the solid block tangential to the heating plate, but also the density difference between the solid and liquid phase is incorporated in the model. The thin film approximation reduces the force balance between the solid weight and liquid pressure, and the energy balance at the melting front into a simultaneous ordinary differential equation system. The normalized model equations admit compactly expressed analytical solutions which include the already approved two-dimensional solutions as a subset. In particular, the normalized liquid film thickness is independent of all pertinent parameters, thereby facilitating to define the transition period of close-contact melting. A unique behavior of the solid descending velocity due to the density difference is also resolved by the present solution. A new geometric function which alone represents the three-dimensional effect is introduced, and its properties are clarified. One of the representative results is that heat transfer is at least enhanced at the expense of the increase in friction as the cross-sectional shape deviates from the square under the same contact area.

In this paper, various structures of the healthcare smart clothing for real-time measurement of vital sign were suggested. The wearing efficiency was evaluated to find out the best ergonomic clothing in the suggested design. The supplementary effects of the clothing components (princess line, double fabric, cushion) on the stable and tight positioning of sensors to the body were evaluated with wear test. Five experimental clothing for male subject were made with closely-fitted shape and they included two representative structure: one was the integrated type of inner and outer garments and the other was the separated type with two garments. Eight subjects in their twenties were participated in the wear test to evaluate the wearing efficiency of experimental clothing. As results, the clothing structure of the separated garments with the inner and the outer shells were evaluated as more efficient and comfortable. However, the effects of clothing components on the light positioning of the sensors to the body surface were not differentiated each other in the subjective evaluation.
