To overcome disadvantages of usual spread foundation in large space structure, some prototypes of a joint of the PHC pile to steel pipe column that directly connects a column to a PHC pile are analytically studied. With the consideration of strength requirement and stress concentration of joint of the PHC pile to column, we suggest the most appropriate one.

This study is designed to analyze the similarity of fit and appearance between 3D virtual torso length sloper with real torso length sloper according to three 3D virtual clothing simulation programs (Optitex, CLO 3D, i-Designer), three body types (A, N, H) and fit status. We selected three representative body type models of females aged 20~30 and got their direct body measurements. Using these body measurements, we developed three 3D avatar body models and made three torso length fitted sloper with long sleeves. Thirty expert fit judges consisting of technical designers and graduate students assessed the similarity of fit and appearance between 3D virtual clothing and real clothing by observing images classified into front, back and side scene. We conducted ANOVA and post-hoc analyses to compare fit and appearance between real clothing and virtual clothing depending on three program. The results showed that CLO 3D represented fit and silhouette most similarly among the programs, especially girths, width and length. i-Designer tended to be relatively good to represent stress fold amount and silhouette. Optitex was assessed relatively better in expressing ease amounts in torso girths and armscye girths, but relatively worse for width, length, stress fold amount and silhouette.

난류유동에 의한 소음은 계산비용의 관점에서 음향 상사법을 이용하여 전산유체 기법과 결합해 다양한 해석모델이 연구되고 있다. FW-H 음향상사법을 이용한 유동소음해석의 연구가 활발히 이루어지고 있으나, 기존 문헌들의 결과에서는 계산비용의 관점에서 난류유동에 의한 소음성분을 생략하고 있다. 그러나, 최근의 연구에서 유동소음특성에 있어 난류소음의 중요성이 밝혀진바 있다. 본 논문에서는 RANS 난류모델과 투과성 경계면을 이용한 Permeable FW-H 음향상사법을 이용한 난류유동소음해석에 대해 연구하였다. 2D 실린더에 대하여 직접적으로 변동압력을 추출하는 직접법과 난류성분을 고려하지 않은 FW-H 상사법, 또 난류소음의 성분을 포함하는 Permeable FW-H 방법의 경우를 비교하였다.

It is identified that an initial person who built of ‘Seoul Gyedong Modernized Hanok(former Min Hyeong-gi house)’ used as ‘Bukchon Culture Center’ in present, was not Min Hyeong-gi, but his wife, Yu Jin-gyeong, and she built it when 8 years went on after his death(1879~1973), and the construction year was at the gate of Chuseok in 1921. Yu Jin-gyeong was Head Family’s Eldest Daughter-in-law in family of Yeo Heung-min who was an influential person at the late Joseon Dynasty and was widow who had only son for 3 generations. And she built this house and moved to gain daughter and live futher grandchilds together in law in new nest. It is arranged that an annex surrounds with main building as the central figure. And this house emulates Yeonkeong-dang in backyard of the Changdeok Palace for 'preservation of main building' and Chim-bang-ga-toe applied on a bedroom in a palace is applied around nobleman family's the main room. It is rare case and expresses that a palace factor is borrowed. Yu Jin-gyeong's house is that a tradition Hanok is adjusted closely in city and central and basing mode as 'protective bedding' and building concept as 'a noble and protective architecture' is realized. So it has a character that development of Hangrang architecture is appeared and Head Family’s Eldest Daughter-in-law widow of modern upper class had a special benefit. As well as, a meaning that it is experimental house based on tradition and is build of Hanok with housekeeping as the central figure for appear a form which has minimal Hangrang for housekeeping in yangban family of modern city, can be found.

There are lots of and kinds of stone pagoda and stone Buddhas at Unjusa Temple in Hwasun, Jeonnam, which is thus called as Cheontap(千塔) or Cheonbul.(千佛) Several archaeological excavations have been conducted in Unjusa though, the foundation purpose or background motivation is yet wrapped in mystery. Circular shape is representative pagoda of Unjusa made of round frame or spherical roof but circular stone pagoda is unusual that there is no similar example found in India or China as well as in Korea. Located in the symbolic center, Circular stone pagoda is a key to understand Unjusa. Yundeung(輪燈) is made of stone for circular stone pagoda and there are craft lamp and large lamp. The large lamp, for the palace courtyard on the occasion of Palgwanhoe,(八關會) consists of discs and light on each disc. Outdoor lamp of circular stone pagoda made of stone for permanent preservation purpose. Unjusa is a very special temple with stone-yundeung for circular stone pagoda. In this study, a circular stone pagoda that is the source of yundeung said. Unjusa circular stone pagoda next to the title of 'yundeung pagoda' and proposes to call.

The plastic hinge region of RC pier ensures its nonlinear behavior during strong earthquake events. It is assumed that the piers secure sufficient strength and ductility in order to prevent the collapse of the bridge during strong earthquake. However, the presence of a lap-splice of longitudinal bars in the plastic hinge region may lead to the occurrence of early bond failure in the lap-splice zone and result in significant loss of the seismic performance. The current regulations for seismic performance evaluation limit the ultimate strain and displacement ductility considering the eventual presence of lap-splice, but do not consider the lap-splice length. In this study, seismic performance test and analysis are performed according to the cross-sectional size and the lap-splice length in the case of longitudinal bars with lap-splice located in the plastic hinge region of existing RC bridge columns with circular cross-section. The seismic behavioral characteristics of the piers are also analyzed. Based upon the results, this paper presents a more reasonable seismic performance evaluation method considering the lap-splice length and the cross-sectional size of the column.

This paper presents the theoretical analysis for the flow driven by surface tension and gravity force in an inclined circular tube. The present study introduces detailed mathematical procedures for Casson viscosity model. The equations of velocity distribution and flow rate are developed to describe the displacement of a non-Newtonian fluid that continuously flew into a circular tube by surface tension. The equation of modified volumetric flow shows the complicated form of (10) due to yield stress term, and the equation of velocity distribution which includes the yield stress and inclination angle of circular tube is composed of terms of r and rc as form of (14).

Bar type waveguides are frequently employed as a buffer rod between ultrasonic senor and hard-to-access object in many measurement applications. Difficulty in pulse echo measurements using a buffer rod is caused by spurious echoes due to reflection, mode conversion and interference within the buffer rod of finite size. These spurious echoes degrade the signal to noise ratio (SNR) because of their possible interference with desired target signals. A tapered buffer rod or rods with non-symmetrical cross sections were used before to reduce these unwanted spurious echoes. In this paper, we propose signal processing techniques to remove the spurious echo signals. Experiments were performed in order to examine the refocusing and recovering the initial input waveform in the long range propagation of ultrasonic waves in cylindrical waveguides. Two different time reversal processes (regular TR and reciprocal TR or inverse filtering) are tested and the experimental results were compared

Plates are frequently used in constructing nuclear power plant structures as a structural member. Creating holes in plates, complying with the function, may sometimes is needed. As the buckling may cause the plate to be failed, this study deals with investigating the effects of the thickness of the plate having through holes on its buckling. A range of thicknesses from 1mm to 10mm is considered for the plate to be investigated. Two holes of diameters of 10mm are created in the plate. The load having the magnitude of 1N/m is applied on the left edge of the plate. Both plates with and without holes are investigated. Results showed that thin plates can fail due to geometrical failure while thick plates may fail due to materials failure. The maximum difference in buckling load between the plate with hole and without hole has occurred for the plate having the thickness of 6mm.

One-dimensional flux theory (1DFT) is conventionally used for design of secondary clarifier of wastewater treatment plant. However, the 1DFT cannot describe turbulence, density current, shape parameters of the clarifier. In this study, we optimized the configurations of influent guide baffle and effluent baffle through the simulation using computational fluid dynamics (CFD) and its verification by particle image velocity (PIV) test. The energy dissipating inlet (EDI) without influent guide baffle (0°) showed the best efficiency for minimizing downward velocity under the center well of the clarifier. The lowest velocity distribution around the effluent weir region could be obtained with the McKinney baffle (EB-2). The performances of the influent and effluent baffles were clearly verified by PIV test results.

In this study, to resolve the brazing type circular saw, the insert type circular saw has designed and made. Also, to confirm the performance of new type circular saw, the various experiments were carried out under condition of tip's shape and machining conditions.

This study aims to conduct a investigation on the gusset of a Kimono sleeve to achieve excellent movability through an evaluation of its fit wearing by conducting comparative research in terms of the length of the gusset pattern according to sleeve angle, which having a great effect on the wearing and activity of the top of a Kimono sleeve. A prototype was manufactured by developing the basic Kimono sleeve based on the method of Ernestine Kopp’s basic bodice pattern. The sleeve angles which was applied to the prototype pattern of the Kimono sleeve ware approximately 50°, 70° and the gusset was diamond-shaped which has a width of 10cm and lengths of 9cm, 10cm and 11cm. As a result, in the case of 55° of the sleeve angle, the angle was gradually increased as the length of gusset was extended, although, in the case of 68° of the sleeve angle, there was not remarkable effects between increased gusset length and the value of the angle. This result could be analyzed that the gusset did not affect remarkably since the sufficient movability was gained with only the angle in the case of 68°. Also, in the results of experiment on 55° angle, as 9cm, 10cm and 11cm of length of gusset commonly indicated over 70° in average, it was found that the movability was obtained sufficiently in every part.

고속도로 영업소 진입로에는 운전자에게 주의환기를 주기 위해 횡방향 럼블스트립이 설치되어 있다. 이러한 럼블스트립은 대부분 직사각형 형상을 갖고 있다. 럼블스트립의 형상에 따라 소음의 특성이 다르게 나타나는 것으로 알려져 있다. 본 연구에서는 직사각형 형태의 럼블스트립을 원형의 럼블스트립으로 개선함에 따른 소음특성 변화에 대한 연구를 수행하였다. 서울외곽순환고속도로 영업소 광장에 개선된 원형 형상의 럼블스트립을 적용하고, 사후 모니터링을 실시하여 개선 전·후의 소음특성에 대해 분석하였다. 본 연구 결과, 럼블스트립의 개선 전·후 소음특성은 개선후의 교통량이 증가했음에도 소음은 감소하는 것을 알 수 있었다. 차량주행속도는 개선 전·후 모두 약 58km/h로 거의 유사하게 나타났다. 원형의 럼블 스트립이 직사각형 형상의 럼블스트립보다 시간대별로 약 1~3dB(A)의 소음저감 효과가 나타났다. 이런 현장적용의 결과를 볼 때, 횡방향 럼블스트립의 다양한 규격(럼블스트립의 간격, 깊이, 형상 등)에 대한 추가적인 연구를 진행하면 더 우수한 성능의 럼블스트립 규격을 개발할 수 있을 것으로 사료된다.

One of the distinguished literary critics in the 20th century Northrop Frye is fully qualified to be remembered and positively reevaluated in the study of literature and religion. However, his literary world has not been adequately studied by Korean scholars and literary critics. For this reason the purpose of this paper is to introduce his literary world and examine it with the perspective of literary-biblical scholarship. The archetypal criticism has been regarded as his peculiar method for combining myth with proclamation(kerygma). According to him, the Bible is literature wearing the cloth of a sufficient metaphor. And in the Bible there are various mythic stories built in metaphor. In many cases myth reveals its own meaning in a form of typology. Typology is a manner of combination between archetype and antitype. The Old Testament is combined by typology with the New Testament. Frye pays attention to the importance of myth in the Bible in the atmosphere of depreciation of myth in the field of biblical studies, which was initiated by the biblical scholar R. Bultmann. His schematic framework stands on the archetypological interpretation of the Bible. Frye constantly negotiates Christian typology and mythic archetype. Also he enriches typology with patterns drawn from comparative anthropology. His archetypological interpretation surely widens our eyes to see the mythic wholeness and unity of the Bible. Of course there has been some criticisms of his insights and method. That is, his reading of the Bible through the archetypology revives a form of Christian supersessionism that detaches the Hebrew Scriptures from the shifting complications of their particular realizations. However, his academic achievements cannot be depreciated by few problems. As he quotes Bruno’s saying(Est aliquid prodisse tenus) in the introduction of the Great Code, it is great that he preceded to a certain extent in the study of literature and religion.

This paper presents the theoretical analysis for the flow driven by surface tension and gravity force in an inclined circular tube. The governing equation is developed to describe the displacement of a Newtonian fluid that continuously flew into a circular tube by surface tension, which represents a second-order, nonlinear, nonhomogeneous and ordinary differencial form. It was found that the theoretical predictions of the governing equation were excellent agreement with the unsteady state solutions for horizontal tube and the results of force balance equation for steady state.

The founder of the ‘Paik In - Je House in Ga Hui Dong’ in the Bukchon Hanok Village was found as Han Sang- Ryong (1880.11.14. ~ 1947.?) and the time when it was built was by the late June in 1913. Han Sang Ryong was the director of the HanSung Bank during the Japanese colonial period and he was the industrialist in the management committee and the economy coordinator in the economic area. The way how he could accumulate the huge amount of money was because his Uncle Lee Yoon Yong and Lee Wan Yong brothers were participating in various concessions under the protection of the colony government such as Chosun colonial government. Through seven years of preparation for building the mansion, the social function he presented to his house was ‘the house built for the banquet hall’. He invited many celebrities of politics and economy to this house and built his fundaments for his social activity through interactions. To solve the construction concept, he used the way of ‘duplicity and juxtaposition’, and his mansion was reborn as a modernized urban Hanok through the reinterpretation by his program out of the old Confucian rules. Han Sang Ryong’s mansion is significant and valuable in the period since it was a pioneer in challenging the creative housing in the developing stage of Hanok in early modern era, and the highest social level people were trying to show off through the Hanok as a product.
