  • Color is infinitely more complex and challenging when the human element is factored in. The nature of fashion presents additional issues that must be addressed, allowing for even greater possibilities. Fashion trends and fashion colors could be used as a starting point for investigating many possible applications in fashion industry. Modern fashion industry received various information from many medias. Fashion trends and fashion colors must be referred to primarily when planning fashion goods among so much information. In this study, changes in fashion trends and fashion colors from 1966 to 1995 were investigated. The results indicated fashion trends and fashion colors were involved with community, culture and economy. Furthermore, important characteristics of fashion trends were summarized. In recent 30 years fashion trends and fashion colors appeared practical fashion and natural color, amenity fashion and mild color. According to the fashion changes in sensitivity, the color change was evaluated. Fashion colors displayed changes from sign effect to symbol effect. Especially black changed from minus image to plus image made it important fashion color.

  • A new approach based on cone prism intersection method combined with sorting algorithm is proposed for the fast and robust signed distance field computation. In the method, the space bounding the geometric model composed of triangular net is divided into multiple smaller cells. For the efficient calculation of distance fields, valid points among the triangular net which will generate minimum distances with current cell are selected by checking the intersection between current cell and cone prism generated at each point. The method is simple to implement and able to achieve an order of magnitude improvement in the computation time as compared to earlier approaches. Further the method is robust in handling the traditional sign problems. The validity of the suggested method was demonstrated by providing numerous examples including Boolean operation, shape deformation and morphing of complex geometric models.

  • The posterior and multidirectional instability of the shoulder is a complex problem in terms of diagnosis and treatment. Increased joint volume by redundant capsular ligament has been regarded as a major pathogenesis of the posterior and multidirectional instability. Distinct from multidirectional hyperlaxity, multidirectional instability has symptoms related with increased translations in more than one direction. Recent report that shoulder symptom originates from labral lesion which was created by excessive rim-loading of the humeral head on the posteroinferior glenoid labrum during repetitive subluxation helps us to understand the pathogenesis of such instability. Painful jerk and Kim tests indicate labral lesion in the multidirectionally loose shoulder, suggesting multidirectional instability. Also, painful jerk test is a prognostic sign of failure of nonoperative treatment. The labral lesion can be an incomplete tear or a concealed lesion which often has been underestimated. Operative treatment is indicated when nonoperative treatment has failed. Arthroscopic capsulolabroplasty is a reliable procedure, which not only provides capsular balance, but also restores the labral height.

  • Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures

  • In this paper, we propsoe a new method of th ecommunication system for cooperative behaviors and works in collective autonomous mobile robots. A communication function among the collective robots is essential to intelligent cooperative works. In genral, global communication is effective for small number of robots. However when the number of robot goes on increasing, this becomes difficult to be realized because of limited communication capacity and increasing amount of information to handle. And also the problems such as communciation interfeence and improper message transmission occur. So we propose local communication system based on infrared sensor to realize the cooperative behavior among robots as the solution of above problem. It is possible to prevent overflow of information and exchange of complex information by fusion sign board model which transmits the information to unspecified robots and message passing model which communicate a specific robot. And we formularize optimal communication range by analysis of information propagation mechanism from the proposed comunication system. At last we verify the effectiveness of the proposed communication system from example of cooperative works.

  • In this paper, we present a real-time cattle action recognition algorithm to detect the estrus phase of cattle from a live video stream. In order to classify cattle movement, specifically, to detect the mounting action, the most observable sign of the estrus phase, a simple yet effective feature description exploiting motion history images (MHI) is designed. By learning the proposed features using the support vector machine framework, various representative cattle actions, such as mounting, walking, tail wagging, and foot stamping, can be recognized robustly in complex scenes. Thanks to low complexity of the proposed action recognition algorithm, multiple cattle in three enclosures can be monitored simultaneously using a single fisheye camera. Through extensive experiments with real video streams, we confirmed that the proposed algorithm outperforms a conventional human action recognition algorithm by 18% in terms of recognition accuracy even with much smaller dimensional feature description.

  • The prominent malar region has been recognized a sign of youth and beauty in caucasian who generally have a dolichocephalic and long face. But in the orients, especially Koreans who generally have a mesocephalic or brachycephalic face, it is considered an agressive, unesthetic facial appearance. So many patients require the shaving of prominent malar eminence and arch, and many methods of its reduction have been devised. For the exposure of malar complex, infraorbital skin incision, intraoral approach, preauricular approach, supraauricular scalp incision, and coronal approach have been used. And for the reduction of bony structure, direct shaving, contouring and repositioning of the malar complex after extirpation, and medially fracture of zygomatic arch have been used with its own merits. We performed the reduction malarplasty through intraoral approach. After two parallel oeteotomy at medial part of the zygomatic bone, the midsegment is removed. The posterior arch of zygoma was bended or green stick fractured. When more correction was required, the posterior arch was fractured medially through the step incision at skin. This method has a some advantages. Compared with the method for extirpation of malar complex, the infection rate is diminished, the resorption is small because of no free bone graft. And cheek drooping is prevented. Compared with the method of coronal approach, the surgical trauma is minimal. Now we report some cases of reduction malarplasty performed through intraoral approach and disscus the surgical technique and results.

  • 본 논문에서는 단일경계 표면플라즈몬 도파로의 모드특성을 잘 이해하기 위해 복소차분도표를 제안한다. 기존의 표면플라즈몬 모드는 군속도의 부호가 바뀌는 부분을 기준으로 분류되었는데, 여기에서 군속도는 표면플라즈몬 모드 진행방향의 전파상수와 광자 에너지에 대한 분산 관계식에서 접선의 기울기이다. 표면플라즈몬 모드는 진행방향에 대해 수직한 방향의 전파상수도 가지고 있기 때문에 이를 종합적으로 이용하여 모드를 분류하는 것이 필요하다. 복소차분도표는 전파상수의 실수 부와 허수 부의 차이를 변수로 하여 나타낸 도표로서 이를 이용하면 모드 분류가 가능하고 또한 광자 에너지에 따른 종합적인 전파상수의 변화 경향을 살펴보는 것이 용이하다.

  • It was early in the $20^{th}$ century when the space was begun to say through the mutual circumstances of form and contents. Adrian Forty explained that the characteristics of space can be divided into three steps by the period: a space of enclosure, a space as continuum and a space as an extension of the body. And there is common condition that all three spaces are accompanied by the form. In the new thinking of architectural form in terms of text in modern society, architecture becomes to more complex to understanding. Saying that there is nothing outside text (Il n'y a rien en dehors du text.) in the world, Jacques Derrida insisted the world to be texted and not to be special centrality, where can be existed by difference and delay its meaning. Text is the structural meaning (sign), not a metaphorical one (symbol). Without the symbol, the architecture can be recognized as text with signing to the form. For that, there is a question how can be explained the space in terms of text extracting the meaning and the symbol. Absolutely not intended by Mies van der Rohe, but in his works of houses and pavilion, its characteristics and traces of text can be seen. If it is possible to analyse his works in the textual view, space of Mies will be found in the same direction of text. And it will be an important opportunity to re-evaluate the space of Mies works standing in the heart of Modern Architecture.
