Recently, it is important to process multimedia data efficiently. Especially, in case of retrieval of multimedia information, technique of user interface and retrieval technique are necessary. This paper proposes a new technique which detects cuts effectively in compressed image information by MPEG. A cut is a turning point of scenes. The cut-detection is the basic work and the first-step for video indexing and retrieval. Existing methods have a weak point that they detect wrong cuts according to change of a screen such as fast motion of an object, movement of a camera and a flash. Because they compare between previous frame and present frame. The proposed technique detects shots at first using DC(Direct Current) coefficient of DCT(Discrete Cosine Transform). The database is composed of these detected shots. Features are extracted by HMMD color model and edge histogram descriptor(EHD) among the MPEG-7 visual descriptors. And detections are performed in sequence by the proposed matching technique. Through this experiments, an improved video segmentation system is implemented that it performs more quickly and precisely than existing techniques have.

The various colors and transparency of DSC and operability unrelated with directions greatly expand the use of BIPV, as a multi-functional composite of module. Therefore the possibility of DSC BIPV is examined by the case study and the analysis and then its applicability is examined. Most of the DSC BIPVs, which are found through a total of six case studies and analyzes in Korea and abroad, are mainly implemented with window glass and shading devices. This is related to the DSC transparency property. Improvements are due to the irritation of the eye due to the color of the red module. Therefore, it is important to take into account the color of the BIPV window depending on the use of the building and the room. Meanwhile, some colors of application model may stimulate eyes and such colors should be considered by use of buildings and rooms in the application of BIPV window. DSC BIPV has prospective diffusibility with the development of flexible module for the application of building surface.

Except for traditional industrial art and history of design development, Korea jewelry industry before 1980's, had little meaning in the aspect of marketing and business. Domestic jewelry market which have changed from the value of goods to value of ornaments, faced important transition point for jewelry industry by the chance of in Asian Game held in 1986, and money of overseas traveler after 1980s. The rapidly-grown Jewelry field by the introduction of detail casting method to make it possible mass-production of the products before 1990's, began to change into new system, with introducing CAD/CAM after 1990's. Jewelry industry has changed from manual work called handmade to the detail casting industry based on master for mass-production. For this, the development of master, with the design development, have been suggested as important task to jewelry industry firms, and by the introduction of CAD/CAM, the diversification of design and master development has been made up. In this study, we would try to find out current status of domestic jewelry field and to understand CAD/CAM, and advantage of CAD/CAM, and through this, suggest good solution to precipitate domestic jewelry market.

Modern figurative work is designed to have more creativity and characteristic traits by pure thought of the formative ceramic arts. In compliance with the demand which is various the design development could be satisfied an individuality and a taste is become accomplished. In this view, this study looks over expressive aspect of Cubism to present partition as a independent formative ceramic arts is able to contribute emotionally to our whole lives. In this procedure, this work is produced to express a three-dimensional effect and a spatial effect, approaching a figurative side. This is to overcome the limitation of Cubism art expressed in a two-dimensional surface in spite of its multi-dimensional observation of a given object. Accordingly, this study tries approaching pre-understanding of expressive aspect of Cubism which was the important turning-point in 20c art and expansion of the modern ceramic art field before producing the work. This study shows the possibility to become a creative and practical ceramic art work, approaching the new point of view breaking from the established conception. Consequently, the field of ceramic art could be expanded to a part of modern ceramic art as an object of study in art of life.

Flame structure and extinction mechanism of counterflow methane/air non-premixed flame diluted with nitrogen are studied by NASA 2.2 s drop tower experiments and two-dimensional numerical simulations with finite rate chemistry and transport properties. Extinction mechanism at low strain rate is examined through the comparison among results of microgravity experiment, 1D and 2D simulations with a finite burner diameter. A two-dimensional simulation in counterflow flame especially with a finite burner diameter is shown to be very important in explaining the importance of multidimensional effects and lateral heat loss in flame extinction, effects that cannot be understood using a one-dimensional flamelet model. Extinction mechanism at low strain rate is quite different from that at high strain rate. Low strain rate flame is extinguished initially at the outer flame edge, the flame shrinks inward, and finally is extinguished at the center. It is clarified from the overall fractional contribution by each term in energy equation to heat release rate that the contribution of radiation fraction with 1D and 2D simulations does not change so much and the overall fractional contribution is decisively attributed to radial conduction ('lateral heat loss'). The experiments by Maruta et at. can be only completely understood if multi-dimensional heat loss effects are considered. It is, as a result, verified that the turning point, which is caused only by pure radiation heat loss, has to be shifted towards much lower global strain rate in microgravity flame.

The three important phases in the development of ligand immunoassays are identified and summarized. The competitive radiolabelled hormone measurement had been developed in the first and early in the second generations(1950s to 1960s), such as radioimmunoassays(RIA) or immunoradiometric(saturation) assays(IRMA), and used in all most of the hormone and also analyte in biological samples. In the second generation, ultrasensitive non-isotopic immunoassays(NIA) were developed using monoclonal antibodies(McAb), labelling the McAb and high specific activity non-isotopic labels. After their usefulness, advantages and disadvantages has been evaluated and non-competitive methods are discussed. The chip/microarray based multianalyte ligand assays(microspot or genechip methods) are developed and known as alternative ones in the third generation. We summarize the developments of NIAs and its usefulness, and then introduce briefly the new ligand assays.
