In this paper, special purpose arithmetic unit for mobile graphics accelerator is designed. The designed processor supports six operations, such as $1/{\chi}$, $\frac{1}{{\sqrt{x}}$, $log_2x$, $2^x$, $sin(x)$, $cos(x)$. The processor adopts 2nd-order polynomial minimax approximation scheme based on IEEE floating point data format to satisfy accuracy conditions and has 5-stage pipeline structure to meet high operational rates. The SFAU processor consists of 23,000 gates and its estimated operating frequency is about 400 Mhz at operating condition of 65nm CMOS technology. Because the processor can execute all operations with 5-stage pipeline scheme, it has about 400 MOPS(million operations per second) execution rate. Thus, it can be applicable to the 3D mobile graphics processors.

In this paper, we propose user authentication methods using a microphone and a speaker in smart phones. The proposed methods guarantee that the user is located close to the target device by transmitting the challenge via an audio channel. We propose two authentication methods; user authentication for a PC or a website using a smart phone as a hardware token, and user authentication to log on to a smart phone using a PC as a token. Because our methods use typical peripheral devices such as a microphone and a speaker, they do not require any special-purpose hardware equipment. In addition, the elderly and the handicapped can easily use our methods because the methods are activated by simple operations.

Nowadays as many Grid communities appear, the requirement of singlepoint-to-multipoint data transfer in Grid environment is growing. In a typical LAN or a special purpose network environment, a multicasting technology was used in such a data dissemination transfer case. However, compared with unicasting fouler performance transfer performance the multicating transfer is worse, and the obligation of a special hardware setting makes it difficult to implement in common Grid environment. Therefore, in this paper we propose on effective data dissemination mechanism for Grid environment named DDMG(Data Dissemination Mechanism for Grid), DDMG uses P2P(Peer-to-Peer) mechanism and Globus XIO library to improve the performance in a data dissemination process and to support heterogeneous protocols in Grid environment. We also evaluate the performance of DDMG mechanism in LAN and WAN environment by comparing with unicast transfer.

Recently, Korea has been established and operated International Schools manifesting to improve the nation's capacity of the foreign languages skill and to cultivate internationally trained professional manpower. In order to achieve the vision of a world-class educational organization, it has to be designed for the facility standards to meet the international accreditation standards. Therefore, the main purpose of this study is to research about basic resources through comparison of facility conditions between public schools in Korea and international accredited schools. By comparing those two different plan drawings are found the following things. First, Schools which established with International Accreditation Standard are prepared detailed criteria for the facility, Furthermore information about the furnishings included, in addition to specific equipments for classes are stated to be prepared. Secondly, it is more effective when special classrooms such as music and science are equipped with various spatial elements, enough educational equipment storage, teacher's study rooms, practical training rooms and student's activity rooms to support various teaching programs and learning efficiently. Lastly, there was a clear tendency that not only hardware but also software standards for the audiovisual room and library have been more enhanced to enable multidisciplinary educational approaches with the recent education training trend.

In order to widely use volume rendering technology in practical fields, a user should be able to control the classification parameter interactively and extract a meaningful information easily from the 3D data as fast as it can be. Previous work on an accelerating volume rendering reconstructs an isotropic volume from an anisotropic one and classifies in pre-processing time and then renders the classified volume rapidly in run time. But, this traditional step may result in long pre-processing time and no real-time feedback. In this paper, we present an efficient classification and rendering method that allows a user to set the opacity transfer function interactively at rendering time on a personal computer without special-purpose hardware.

This is a successive study of the development and application of an electronic safeguard system for elderly men (senile dementia patients) who wander without purpose because of declined mental capability, while retaining their physical ability. The new safeguard system is designed with some additional functions on the basis of the previously developed system. Firstly, alarms are designed not to disturb other patients at night, so that informations about doors from which the patients go out may be transmitted to helpers individually by radio paging system. Secondly, the system hardware can be set up anywhere without laying particular signal transmission cables, provided that there exist AC power distribution lines for the utilization as a transmission line of signals to alarm indicators. Thirdly, it is possible to have a grasp of the whole states of the safeguard systems at the center of operation by monitoring the operational state of each system with a necessary data acquisition according to its instruction through telecommunication network. Thus, each safeguard system can be economically supplied to the special nursing homes and the helpers are ensured more released from physical and psychological burdens so that they can devote themselves to the care of senile elderly men, thereby improving their patients' comfort and human dignity.
