  • In the view point of further reducing the inter-symbol interferences studied in our previous paper 〔1〕, a quadrature pair of wavelet-based filter banks that are composed of a pair of cosine and sine modulated filter banks is applied to MC-CDMA transmultiplexing. For that fact, the symbol duration gets twice longer than the one in , 〔1〕, the interference effects due to channel overlapping and Doppler spread can be effectively alleviated while increasing the channel utilization efficiency. Moreover, the well-known wavelet properties are exploited to design the prototype filter in such a way to maintain the size of sidelobes much smaller than those of the FFT, the interference reduction effect can be further obtained. To verify the behavior of our proposed quadrature filter bank based MC-CDMA system, the reverse-link bit error rates with respect to SNR under Rayleigh fading and additive white Gaussian noise channel environments are computed. The results show an improved system performance over the conventional MC-CDMA.

  • If the motion is universal over the differences between the ancient age and the modern age, and between primitiveness and civilization, It is required to be studied, which make it possible to discover the universally valid interpreting elements of various societies and cultural phenomena. The study on the motion, as a base of universal motion study on animation and character modelling is considered as a very important part. The sampled motion prototype was classified by the continuity and the synchronicity that is a basis of modular analysis and of motion flow. Koguryo's mural paintings in old tombs has been the heritage and the symbol of the nation's historical identity and pride in Korean history. Koguryo is obviously a part of Korean history, which are of Korean elements. Accordingly, the mural paintings that this study has explicated is the origin as well as the history of Korean visual animation history, while the analysed and restored motion prototype is a module of Korean motion with golden section proportion.

  • Myths and architectural spaces are cultural products symbolizing ideologies and objects respectively. Myth has the structure and the contents of a unique view of the world that reflects thoughts and representations of the nationalities. This study is about 'the spaces of the memory' adapted by the mythic tradition among many aspects of the Japanese tradition. The process of this study is illustrated as follows: At first, it mentions the concept of Gilbert Durand's mythic imaginaries and prototype with the method on how the myth is applied to the architectural spaces in the cultural context. Secondly, It clarifies basic meaning arrangement of the Japanese traditional spaces related to the myth. It shows sourceful 'prototipical system' that lies in the relation between thoughts and representations, regarding the shinto's spaces in terms of mythical imaginaries and Japanness. Thirdly, it ascertains mythical structure represented in the traditional space designs on terms with 'prototype' from symbolic system of the myth. It selects the cases among Japanese contemporary architects's works designed after 1960's, and analyses the meanings. In conclusion, it clarifies that this way can be a suggestion as the space design method combining the human's imaginary property with the time-stratigraphic region, and offering creative ideas for the strategy of the space design brand image that embraces a wide range of culture, ecology, and sensibility.

  • This study was done for the proposal for improvement for junior sportswear which is substitutable as uniforms in the form of elementary school and physical education uniforms by analyzing detailed features through investigation. Accordingly, we developed a prototype design for physical education uniforms as a symbol of the school to enhance the aesthetic and functional satisfaction. The results are as follows. When we developed physical education uniforms, we put activity on our first priority while taking the improvement in both aesthetic and functional aspects into consideration. In addition, we tried to make sure the uniforms reflect the refined and trendy elements to meet students needs to satisfy their aesthetic sense in dress. Reflecting the improvement proposals and preferences of the students, six different prototype designs were developed and evaluated on the basis of two concepts of "new basic" and "trendy". The highest ranking, the physical education uniforms design 1 is based on new basic concept and characterized with slim fit considering activity which will be worn as fall/winter physical education uniforms. Design 1 uses ottoman functional knit as a fabric material which is not only students favorite but also good in both flexibility and warmth. Top with style of high-neckline collar and full open zip-up is simplified with the incision lines and detail. It is a set-in sleeve design in which blue and yellow collars signifying school color are properly placed along with the incision lines in harmony.

  • This study investigated dialog sequence prototype that was the structure of communication, which could be shown in family counseling conversation between therapists and clients. The study was intended to review the process stages of family counseling through literature review, and divided functional phases into 'atmosphere formation phase', 'family evaluation phase', 'persuasion phase of cognitive change', 'confirmation phase of change experience', and 'termination phase'. The study selected two family therapists and 30 clients for research objects. They allowed data collections for the study after the explanation about the research objects. The transcribers were trained by the consent of transcription, which used particular symbol for verbal and nonverbal contents in conversation. The transcribed data were analyzed by dialog grammar, one of the linguistic dialog analysis method developed by Hundsnurscher(1994). This study described and explained dialog sequence prototype that displayed in conversation between family therapist and client through the total sessions in family therapy. The study found three types of dialog sequence prototype in 'atmosphere formation phase', eight types in 'family evaluation phase', nine types in 'persuasion phase of cognitive change', eight types in 'confirmation phase of change experience', and eight types of 'termination phase'. Even if the dialog sequence prototype mentioned above cannot be applied to the process of family therapy at its face value, these findings may contribute to beginners in counseling and graduate students majoring family therapy to do practice in counseling. The research has a limitation in which the study investigated dialog sequence prototype of conversation in two persons. Future research needs to include dialog sequence prototype of conversation among more than three persons. Specifically, when a family therapist do family counseling, he/she treats more than three family members as usual. Therefore, the researchers hope that future study investigates dialog sequence prototype between therapist and client, client and client, among therapist, client and other family members.

  • This paper proposes a methodology for automatic hierarchy classification of subtitles in a engineering document by the a fact that heading symbols of subtitles represent a hierarchical structure of the document. The proposed methodology is composed of two methods: extracting subtitles from plan text document and determining hierarchical structure of the subtitles. The subtitles in a document is extracted by comparing heading symbol patterns with predefined heading symbol groups, and the depth levels of the subtitles are determined by analyzing relative location of subtitles according to change of the heading symbol patterns. A prototype module, which can transform a plain text document into a structured XML document in accordance with a hierarchical structure of subtitles, is developed based on the proposed methodology, and the performance of the module is analyzed with 20 engineering documents.

  • In this paper, we have proposed the design and implementation for efficient Command Control and Alert(C2A). Information fusion must be done for knowing the state and identification of targets using multi-sensor. The threat priority of targets which are processed and identified by information fusion is calculated by air-defence operation logic. The threat targets are assigned to the valid and effective weapons by nearest neighborhood algorithm. Furthermore, the assignment result allows operators to effectively operate C2A by providing the operators with visualizing symbol color and the assignment pairing color line. We introduce the prototype which is implemented by the proposed design and algorithm.

  • The vehicle navigation system is developed for helping driver to retrieve driving information more easily and fastly. Navigation System informs driver many pieces of driving information - roadway structure and system, on-line traffic condition, the position of vehicle, route guidance, destination and other information service. As the style of information is diverse and the amount of information is large, driver may have mental and visual overload. The display of information can disturb the driver's attention and this can cause accidents. This state is caused by the defect of human-machine interactions. When the navigation system is designed, human factors - cognitive, judgment, operating - must be considered. The display style must be designed simply and easily, not to be obstacle of human -machine interface. In this study, outside-in view display style and inside-out view display style are compared each other. Two factors are measured. One is cognitive factor-time of cognition on information that is displayed by screen display, cognition error rate. The other is image of screen display - subject's feeling about several styles of display, degree of subject's preference. The prototype of roadway is four kinds - Cross, T-cross, Y-cross and O-cross. Roadway display for test is taken from paper maps. Traffic condition display style, vehicle position display style and route guidance display style are taken from current display style. Traffic condition display style is symbol. Vehicle position display style and route guidance display style are described as color and symbol. The test on screen display is implemented doing given tasks. Then the test is analyzed statistically, The result of test analysis gives the guideline to the designer for the map display of the vehicle navigation system.
