In this paper, we introduce an ubiWarehouse system for the management of automobile parts. Because automotive parts are very various in kinds according to companies, models and manufacture year, it's hard to find exactly the desired parts and to control goods in stock. To solve this problem, we propose the model of context recognizer in which context data are expressed in a systematic type of 5W1H. And initial context data are grouped and integrated, and some conflict context information is solved. Finally user's intention is interpreted and served. As a result, the proposed system can be used to enhance conveniency and correctness of the management of various kinds of part's.

The objective of the study is to know demographic characteristics mobility motivation housing aspiration and housing values of expected purchasers of the small/medium size apartments located at 'H-area' in Ulsan to enhance their level of housing satisfaction through better planning. The result shows that moving motivation housing aspiration and housing values differ as what size respective expected purchasers want. As a regional characteristic the reality-oriented view of housing is apparent in that their interests are focused on the setups or facilities after-service and maintenance and that they think conveniency more important than the edifices' appearance or beauty.

Numerical analysis has been conducted to simulate pedestrian flow in the model of two-storied subway station. Because almost all the subway stations are two or three storied structure, simulations are conducted for the passengers those who get off the train and pass the wicket. Passenger flow analysis is very important factor to design the station and also to manage the operation of subway system. In the subway station, pedestrians move to the horizontal directions as well as vertical ones. Therefore, to consider the movement of pedestrians is necessary for the guarantee of safety and conveniency. As the up and down floors are connected with step, escalator and elevator, the entire movements in the multi-storied station should be simulated as like a 3-dimensional flow. Numerical schemes for the directional sweeping are developed to prevent the dependency on physical structure of station and to determine primary direction and secondary one. By using the developed program, we compared the simulation results of the effects of the location and size of exit and elapsed time.

The broadcasting system for the customer safety and conveniency is one of the important convenience facilities taking charge of customer guidance, emergency situation broadcasts for the people waiting at the platform, waiting lounge and train approaching broadcasts. To maintain this broadcasting facility local management control system(LMC) is needed. LMC observes operation status of the facility components which is set up at station and the observation results are confirmed through out remote management PC installed in the jurisdiction branch office. The staff only observes and confirms the errors of the electrical power source at broadcasting facility components accordingly the real mechanical troubles are detected by on-the-spot survey. this paper deals with existing broadcasting system only acting as a simple observation function and the research of LMC function extension which controls, monitors and tests broadcasting facility.

An automated surface-strain measurement system, named ASIAS, was developed by using the image processing and stereo vision techniques in the previous studies by the corresponding author and his coworkers. This system has been upgraded mainly to improve the accuracy through image enhancement, sub-pixel measurement, surface smoothing, etc., since the first version was released. The present study has still more improved the convenience of users as well as the accuracy of measurement by processing high resolution images 8 mega pixels or more which can be easily obtained from a portable digital steal camera. It is proved that high resolution image processing greatly decreases the measurement error and gives strain data without considerable deterioration of accuracy even when the deformed grids to be measured and the master grids for camera calibration are captured together in the same image, making the whole process of strain measurement much simpler.

In this paper, we describe the effective way of keyboard-hacking prevention and authentication system using a Smart Card. These days the securing information matters for pc-users are becoming more important as the internet business grows rapidly, and the ubiquitous computing environment is open tot everyone. Therefore, PC authentication is necessary to handle the access control to the target PC. Also, the keyboard-inputting information is necessary to be protected properly against the malicious attack. In this paper, we propose the keyboard-hacking protect systems and authentication system using a Smart Card, and show the conveniency and efficiency in the results.

The objective of this study is to introduce the spatial characteristics and the better arrangement of waiting areas in general hospital on comprehensing the patient's behavior as patient call-system and spatial characteristics is characteristics is changed. That is for improvement in the circumstance of waiting area more important than before, and for the patient satisfaction and patient's affirmative judgement of hospital quality by offering the convenience. Through this study, the way of improvement for waiting area can be suggested such as the beeper system, the restructuring of program information, the multiple aim space without hospital program, the reform of the seat's arrayal, the waiting area with conveniency.

Conventional disinfectants and disinfection method are expensive, hazardous and often require long periods of exposure. Recently, there is growing interest in complex disinfection process as a disinfection technique in medical instruments such as endoscope, hand piece bur to improve the disinfection efficiency and conveniency. The aim of this study was to evaluate the performance of a new complex process for the purpose of disinfection of Escherichia coli in water. Three single process (electrolysis, UV and ultrasonic process) was combined dual and triple disinfection process. The order of disinfection performance for E. coli in dual process lie in: Electrolysis + UV > Electrolysis + Ultrasonic > UV + Ultrasonic process. Disinfection efficiency of E. coli and degradation of N, N-Dimethyl-4-nitrosoaniline (RNO, indicating material of OH radical formation) of dual process was higher than that of the triple process (Electrolysis + UV + Ultrasonic process). In electrolysis + UV process, disinfection tendency was well agreed with RNO degradation tendency.

In this paper we propose multi-functional telephone rejecting a simultaneous call at home or small office with several telephones in one line. Also we describe the protocol to transfer a call to the other telephone in different place with ease. So the proposed scheme can protect a personal privacy and provide the conveniency. Since the proposed phone is implemented with Holtek HT95C20P microprocessor, the most of functions can be easily changed accordance with user's needs.

FRT design aims at high-tech vehicles of high efficiency and cleanness, it must materialize the meaning and role as new added value by applying car design aesthetics of a new future-oriented concept. In addition, different from ordinary vehicle design, FRT involves invisible factors such as pleasantness, safety, accessibility, controllability, movability, conveniency, culture, identity, brand image and fashionableness. Because FRT vehicles are transportation means used by various groups of people, they must be approached with the barrier-free design concept. Therefore, in order to enhance the potential of future transportation culture emphasizing creativity based on diversity, it is important to establish core design factors that create new added values and to apply new concepts to their roles.
