In this paper, we introduce a new soft computing technique that dwells on the ideas of combining fuzzy rules in a fuzzy system with polynomial neural networks (PNN). The PNN is a flexible neural architecture whose structure is developed through the modeling process. Unfortunately, the PNN has a fatal drawback in that it cannot be constructed for nonlinear systems with only a small amount of input variables. To overcome this limitation in the conventional PNN, we employed one of three principal soft computing components such as a fuzzy system. As such, a space of input variables is partitioned into several subspaces by the fuzzy system and these subspaces are utilized as new input variables to the PNN architecture. The proposed soft computing technique is achieved by merging the fuzzy system and the PNN into one unified framework. As a result, we can find a workable synergistic environment and the main characteristics of the two modeling techniques are harmonized. Thus, the proposed method alleviates the problems of PNN while providing superb performance. Identification results of the three-input nonlinear static function and nonlinear system with two inputs will be demonstrated to demonstrate the performance of the proposed approach.

In order to enhance encoding speed in dynamic image encoding using H.264/AVC, reducing the time for motion estimation which takes a large portion of the processing time is very important. An approach using graphics processing unit(GPU) as a coprocessor to assist the central processing unit(CPU) in computing massive data, will be a way to reduce the processing time. In this paper, we present an efficient block-level parallel algorithm for the motion estimation(ME) on a computer unified device architecture(CUDA) platform developed in general-purpose computation on GPU. Experiments are carried out to verify the effectiveness of the proposed algorithm.

In this paper, We propose a method of motion interpretation of pedestrian for active traffic signal control. We detect pedestrian object in a movie of crosswalk area by using the code book method and acquire contour information. To do this stage fast, we use parallel processing based on CUDA (Compute Unified Device Architecture). And we remove shadow which causes shape distortion of objects. Shadow removed object is judged by using the hilbert scan distance whether to human or noise. If the objects are judged as a human, we analyze pedestrian objects' motion, face area feature, waiting time to decide that they have intetion to across a crosswalk for pdestrians. Traffic signal can be controlled after judgement.

In this study on the creation of parks in North Korea, which is closely re]toted to the developmental stages in North Korea, park construction plans are investigated according to the following periods: 1) from the Liberation of Korea in 1945 to the outbreak of the Korean War, 2) from the end of the Korean War to the 1950's, 3) 1960's and 4) 1970's and 1980's Major North Korean parks are also presented and common characteristics of park-making in North Korea are analyzed in the following way : 1) the character and function of the parks, 2) the development of landscaping, 3) the creation of unique North Korean parks. This study was conducted through archival research of North Korean documents and it may be limited due to the intrinsic problem of reliability that the documents have, and also to an impossoble on-the-spot survey. However this study is of value because it presents North Korean parks, as yet unpublished in South Korea, and it can be used as valuable information for further study and especially for the planning of parks and green space system in preparation for a probable unified Korea. For a profound stuffy, broader and more accurately detailed North Korean documents must be obtained and opened to the public. A comparative study on the principles of spatial composition and design elements of the parka in South and North Korea mutt also be conducted so as to find a model for the Korean park for a future unified Korea.

This study is examine the scales applied to buildings in the age of Unified Silla through construction sites excavated and its results are as follows; First, scales used in the age of Unified Silla were varied like Jucheok, Dangcheok and Hancheok, but it was generally accepted that Dangcheok was used in Yeongjocheok Since it was found that the scales applied to Dabotap at the Bulguksa temple and main building of the Gameunsa temple belonged to Goguryeo, Yeongjocheok scale used early in the age of Unified Silla was transitional and it was thought that Goguryeocheok and Dangcheok were used togethar. Second, according to actual rulers in Korea, china and Japan, the length of Dangcheok(ruler used in Chinese Tang era) mostly belonged to the extent of $29.25cm\;{\sim}\;30.5cm$(central value: 29,71cm). Third, plane features of main building of temple are assumed that it had five rooms in front compartment until the 7th century and then it was diversified to three, five and seven compartment. The size of compartment was same in the scale of front Eokan and Hyeopkan until late 7th century, but since then the dimension of Eokan tended to be wider than Hyeopkan. It was judged that the front Eokan used triple scales like 9, 12, 15, 18 cheok. Fourth, the length of residential structures was 17.5cheok${\sim}$36cheok and Bcheok was commonly used for front side of structure, The length of official structures was 8.4cheok${\sim}$36.3cheok which is similar to residential structures. However it has been confirmed that each of 9cheok, 12cheok, and 15cheok has been used for Eokan and Hyeopkan which gave presumption that triple scales was used for the measure.

Present study introduces an implementation of product data management (PDM) that can be applied to the design of ship propulsion system. The PDM system is developed based on both object oriented software development environment and Open Scene Graph (OSG) library while the system architecture is modeled by the unified modeling language (UML). Suggested PDM system also integrates the modeling & simulation components required to estimate the performance of ship propulsion system as the product information is represented based on the 3-dimensional digital mock-up (DMU). Finally, functions of the implemented PDM system that is integrated with the M&S softwares are illustrated in order to suggest a practical guidance for the efficient design of ship propulsion system.

Recently, USN applications are in the early stage of commercialization. But, there are still several problems to develop USN applications. It is mainly due to the current development scheme that solution vendors makes all of them including HW, SW, sensor modules. The development of USN applications could be revitalized if three entities such as PC platform developers, PC device vendors, and application developers would do their best as in PC development. In this paper, we suggest an sensor node platform architecture supporting sensor independency to overcome the difficulty of developing USN applications. Traditional platforms like Tiny-OS and Nano-Q+ do not support such sensor independency. At first, we present a unified API for sensor independency, and also suggest an architecture to support sensor independancy. Our architecture results in the revitalization of developing USN applications.

This paper proposes the new high-performance circuit architecture of the transform and quantization for unified video CODEC. The proposed architecture can be applied to all kinds of transforms and quantizations for the video compression standards such as JPEG, MPEG-1/2/4, H.264 and VC-1. We defined the permutation matrices to reorder the transform matrix of the $8{\times}8$ DCT and partitioned the reordered $8{\times}8$ transform matrix into four $4{\times}4$ sub-matrices. The $8{\times}8$ DCT is performed by repeating the $4{\times}4$ DCT's based on the reordered and partitioned transform matrices. Since our circuit accepts the transform coefficients from the users, it can be extended very easily to cover any kind of DCT-based transforms for future standards. The multipliers in the DCT circuit are shared by the quantization circuit in order to minimize the circuit size. The quantization circuit is merged into the DCT circuit without any significant increase of circuit resources and processing time. We described the proposed DCT and quantization circuit at RTL, and verified its operation on FPGA board.
