With the lanuch of the World Trade Organization(WTO) system, National and international trends toward more liberalized regulation of telecommunications terminal equipments drive the globalization of the telecommunications market. Despite of such trends, most countries have long viewed the type approval system as a major hindrance to overseas maketing because of a hodgepodge of diverse type approval system of telecommunications terminal equipments in each country. But, recently, many countries under these situations try to make a better understanding of respective requeirements of each country's many countries under these situations try to make a better understanding of respective requirements of each country'stype approval system, and where possible to strengthen commonalities, through referred to as "multual recognitio" system for the purpose of the development of procedures for hamonization oftype approval system in "one world, one market". Thus, this paper covers the definition, considerations and the case studies of mutual recognition between countries. Also, this paper suggests the desirable and general model of mutual recognition to be applied all the countries, which are being preparing and processing it.g and processing it.

The purpose of this study was to examine the differences between aggressive and nonaggressive boys with the use of a social information processing approach. The subjects were 80 3rd & 6th grade boys selected from a public elementary school in Seoul. The subjects were interviewed individually. Following the presentation of each story, five questions were asked. A 2 x 2 Analysis of Variance was performed for each of the 5 dependent measures. Results showed (1) Aggressive boys were more likely to attribute a hostile intention to the behavior of peer. (2) Aggressive boys predicted their own response as more hostile and aggressive. (3) The 6th graders generated more alternative solutions than the 3rd graders. (4) Non significant results are not reported in the abstract. (5) Aggressive boys were likely to choose an ineffective solution.

In this paper, we present a graphics processing unit (GPU)-based matching technique for the purpose of fast feature matching between different images. The scale invariant feature transform algorithm developed by Lowe for various feature matching applications, such as stereo vision and object recognition, is computationally intensive. To address this problem, we propose a matching technique optimized for GPUs to perform computations in less time. We optimize GPUs for fast computation of keypoints to make our system quick and efficient. The proposed method uses a self-organizing map feature matching technique to perform efficient matching between the different images. The experiments are performed on various image sets to examine the performance of the system under varying conditions, such as image rotation, scaling, and blurring. The experimental results show that the proposed algorithm outperforms the existing feature matching methods, resulting in fast feature matching due to the optimization of the GPU.

This paper deals with the architecture of an information processing model for the human concept understanding required in constructing intelligent man-machine interfaces. The architecture employed is a parallel processing by networking. For this purpose, personal computers are interconnected by LAN and are, in their roles, divided into three levels. A concept has two aspects; i.e., language and image. In the present model, the system as the holistic whole of personal computers together with peripheral devices processes visual information in cognitive level, searching for feasible solutions from a variety of aspects. An image inputted through peripheral systems is categorized and matched with those ever experienced with the aid of that categorization, and thus an image is identified.

In this research, a new quantitative fabric drape evaluation system has been developed using image processing technology. The purpose of this research is to get the more detailed information of fabric drapability quantitatively from digital images captured with a digital camera generally commercialized. The shape parameters of a 3-dimensional geometric drape model were defined as the number of nodes, frequency and amplitude. Also, various statistical information of drape shapes can be obtained using image processing technology and frequency analysis as well as traditional drape coefficients. Hardware system to capture drape images is simply composed of three parts including a digital USB (Universal Serial Bus) camera, a frame cover and a stand for camera to attach to traditional drape tester. The evaluation software coded with the MS Visual C++ is operated under the MS windows 9x above.

A critical issue in the performance of a video-on-demand system is the I/O bandwidth required in order to satisfy client requests. Several approaches: batching, bridging, piggybacking are used ot reduce the I/O demand on the video server through sharing. Piggybacking is the policy for altering display rates of requests in progress fro the same object, for the purpose of merging their corresponding I/O streams into a single stream, which can serve the entire group of merged requests. In this paper, we propose a new policy called an adaptive reservation-based piggybacking that dynamically reserves the I/O stream capacity of video server for popular videos according to video server loads to immediately schedule the requests for popular videos. The performance of the proposed policy is evaluated through simulations, and is compared with that of simple piggybacking. As the result, we know that the adaptive reservation-based piggybacking provides better service probability, average waiting time and percentages saving in frames than simple piggybacking.

같은 도메인 내에 서로 다른 관점을 다루고 중복되는 정보를 포함하는 온톨로지들이 증가함에 따라서, 이들 사이에 재사용 및 공유를 위한 통합이 중요한 과제로 떠오르게 되었다. 또한 도메인 온톨로지로부터 상위 온톨로지를 추출하는 방법에 관한 연구도 온톨로지의 재사용과 공유를 목적으로 진행되고 있다. 본 논문에서 우리는 맵핑을 이용한 온톨로지 통합을 바탕으로 상위 온톨로지 생성 방법을 제안하고, 이를 정형화된 형태의 일반적인 목적을 가지는 온톨로지(general-purpose ontology)로 확장시켜 나가는 방안에 대해 살펴본다. 본 논문에서 제안된 온톨로지들 사이의 매핑은 개념들 간의 관계를 효율적으로 만들고, 해당 도메인에 대한 일반화된 온톨로지는 추후 사용자들의 공유를 용이하게 한다.
