This study is intended to understand an implication and significant of anti-design and Italian radical fashion. Anti-design and radicalism is the main stream or origin and essence of post-modernism which hs been swaying our society at large through modern culture, economy, art, fashion etc, from the latter part of 1960s. In this paper, the author classified the italian radical fashion with the Archizoom, the Alchymia, the memphis fashion. In post-modernism fashion, radical fashion design of the Archizoom, Alchymia and Memphis group is in part a menifesto and in part a noncanonical history of the most progressive and heretical experiments of the world of fashion. Anti-designers of Italy call for a theory an practive in which the old methods and instruments and the old commendments of modernism are banished. They looked on fashion as material culture, a creative field with its own independent foundation and endowed with its own strong artistic intuition. IF radical design is dead, the energy it has stirred up is still alive nd kicking. One of the most progressive and well-informed culture milieus in Milian, seved as a point of reference for the vanguard of fashion.

One stream of the GDSS(Group Decision Support System) research is to investigate how GDSS affects decision performances of small groups according to task types, support features, meeting facilitation modes and meeting environments. But little study has investigated the effects of group member characteristics on group decision processes and outcomes depending upon whether GDSS is provided or not. To date, most GDSS studies have not controlled group member characteristics(e,g. personality, sex, decision style) in laboratory experiments. However, this study included the decision styles of group members as an independent variable. Therefore, this study investigated how differently members of two different decision styles perceive the use of GDSS in small group meetings through lab experiments. The two decision styles are feeling(F) style and thinking(T) style. We found that the effect of GDSS is a function of individual's decision style only in the communication thoroughness variable. The decision style is a statistically significant factor that can mediate the effects of the group support technology on the perceived communication thoroughness. Specifically, the GDSS is positively related to participants' perception about satisfaction on decision process, goal achievement, communication thoroughness, degree of influence-outward and effort for achieving meeting goals.

The effective extraction of key frames from a video stream is an essential task for summarizing and representing the content of a video. Accordingly, this paper proposes a new and fast method for extracting key frames from a compressed video. In the proposed approach, after the entire video sequence has been segmented into elementary content units, called shots, key frame extraction is performed by first assigning the number of key frames to each shot, and then distributing the key frames over the shot using a probabilistic approach to locate the optimal position of the key frames. Moreover, we implement our proposed framework in Android to confirm the validity, availability and usefulness. The main advantage of the proposed method is that no time-consuming computations are needed for distributing the key frames within the shots and the procedure for key frame extraction is completely automatic. Furthermore, the set of key frames is independent of any subjective thresholds or manually set parameters.

This paper describes the effect of the incidence angle on the turbulence structure in the wake of a turbine rotor blade at the low inlet free-stream turbulence level. For three incidence angles of -5, 0 and 5 degrees, mid-span energy spectrum as well as mid-span profiles of mean velocity magnitude and turbulence intensity are reported at three downstream locations in the wake. Vortex shedding frequencies are obtained from the energy spectrum. The result shows that as the incidence angle changes from-5 to 5 degrees, the boundary layer on the suction surface tends to be thickened, which results in widening of the wake. Strouhal numbers based on the shedding frequencies have a nearly constant value of 0.3, independent of tested incidence angles.

In the present investigation, we have studied the magnetohydrodynamic (MHD) heat transfer of peristaltic flow in a tube. The analysis is made without imposing any assumption to obtain the streamline and isothermal line directly. Galerkin's finite element method has been used on the governing Navier-Stoke's equation in the form of ${\psi}-{\omega}$. The graphs of the computed longitudinal velocity, temperature and pressure are plotted against different value of the emerging parameter by using the stream function and vorticity. The results are valid beyond the long wavelength and the low Reynolds number limits. We conclude that higher values of the parameters are not independent of the time mean flow rate.

This thesis is a study to Haengnang(行廊, a series of buildings) of Sijeon(市廛, licensed markets), which was built along with palaces, Jongmyo(宗廟) and roads in order to establish Hanyang(漢陽) as the capital of Joseon (朝鮮). Sijeon, built on Jongno and Namdaemun-ro, the main roads in Hanyang, created two-row lands on both sides of the road, and formed Pimat-gil as an inner road between the Jeonbang and Doga. The formation of the city proceeded along with the maintenance of the water path, and the situation of the water path parallel to the flow of Sijeon was achieved. The Sijeon building was a spatial structure managed by independent rooms as a result of reflecting the unique operation method of Sijeon. The Sijeon of Hanyang had an impact on the formation of land, architecture, roads, and waterways, and acted as a major factor in determining the urban spatial structure of Hanyang City.

한국 동해안의 가장 대표적인 연어과 어류인 연어(Oncorhynchus keta)의 집단 분석을 위한 연구가 국내에서는 많이 수행되지 않았다. 최근 연어과 어류의 계군을 분석하는데 유전자를 이용하는 방법들이 시도되고 있으며, 단일염기다형성(SNP)을 이용한 집단 구분 방법이 점차 많이 이용되고 있다. 본 연구에서는 한국 연어의 소상하천간 유전적 유사성과 차이점 및 일본 연어와 유전적 관계를 살펴 보기 위하여, 미토콘드리아의 COIII-ND3-ND4L 지역 720 bp 염기 서열을 분석하였다. 한국의 3개 지역(고성 북천, 양양 남대천, 울진 왕피천)에서 채집된 108개체와 일본의 2개 지역(홋카이도의 마시케와 하코다데)에서 채집된 44개체를 분석하여 29개의 haplotype을 확인하였다. 유전적 다양성은 남대천 연어에서 가장 높고 하코다데에서 가장 낮았다. Pairwise $F_{ST}$와 AMOVA를 이용한 집단 분석 결과, 한국 연어는 소상하천간 유전적 차이가 거의 없으며 일본 연어와도 크게 구분되지 않았다($F_{ST}<0.07$). 그러나, haplotype 유사성으로 본 각 개체의 유전적 관계는 한국 연어의 일부(약 25%)가 일본 연어와 구분되는 독특한 유전적 가계(lineage)를 형성하고 있으며, 국내 남대천과 북천 연어에는 왕피천과 구분되는 연어 가계가 존재함을 보여준다.

This study seeks what kind of factors influence to locate dwellings and to establish scenic spots in nature by a case study focused on a meandering stream. The study specially concentrates on the interrelationship between both residences and beautiful sceneries and a meander cut-off-area that reveals a special topographical characteristics, located at Samji village in Youngyang-eup, Youngyang-gun, Koungsangbuk-do. The meander cut-off area, developed at the middle or upper reaches of a river, often makes up specific landscapes such as precipitous cliffs, sheer cliffs and caves. And the area where is specially created by sudden change of flow due to erosion ;perceived by the cut surface to be the most beautiful scenic spot. These beautiful landscapes were used to be called as Dae, Dam or Gul and managed by Confucian scholars who enjoy refined taste and devote themselves to the study in nature. Moreover, the Ku-Hado-literary means the area of ex-flow-made the scholars' lving with a well prepared basis for agriculture where supplied a cornucopia of organic matters and water. The merit of agriculture made it possible that the scholars became economically independent, and the fact might be the essential point why the meander cut-off area took noticed. Actually, Cho-family has been in Smaji Village for generations, producing a large number of scholars and keeping the actual power of the region. The physical shape of the meander cut-off area, cozily surrounded by mountains, is considered as a good place for the dwelling due to the influence of traditional sight of view for location and P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world. It is a fruit in it own way that we could find the ancestors' discernment and wisdom from this study, who have lived their lives adapting themselves to the given natural environment and also utilizing the nature wisely. But this is a current-argued study on the meander cut-off area. Follow-up studies have to be continued about the landscapes of the meander streams and the meander cut-off areas scattered all over the country except Samji Village and draw the characteristics from the comparative analysis.

The completely mixed flow and plug flow (CAP) water quality model was developed for streams with discontinuous flows, a condition that often occurs in low base flow streams with in-stream hydraulic structures, especially during dry seasons. To consider the distinct physical properties of each reach effectively, the CAP model stream network can include both plug flow (PF) segments and completely mixed flow (CMF) segments. Many existing water quality models are capable of simulating various constituents and their interactions in surface water bodies. More complicated models do not necessarily produce more accurate results because of problems in data availability and uncertainties. Due to the complicated and even random nature of environmental forcing functions, it is not possible to construct an ideal model for every situation. Therefore, at present, many governmental level water quality standards and decisions are still based on lumped constituents, such as the carbonaceous biochemical oxygen demand (CBOD), the total nitrogen (TN) or the total phosphorus (TP). In these cases, a model dedicated to predicting the target concentration based on available data may provide as equally accurate results as a general purpose model. The CAP model assumes that its water quality constituents are independent of each other and thus can be applied for any constituent in waters that follow first order reaction kinetics. The CAP model was applied to the Geum River in Korea and tested for CBOD, TN, and TP concentrations. A trial and error method was used for parameter calibration using the field data. The results agreed well with QUAL2EU model predictions.
