Objectives : The purpose of this study is to show the differences of mental stress measured with heart rate variability (HRV) and to evaluate the effects of Aromatherapy under mental stress, according to the depression index. Methods : The volunteers were allocated into 2 groups by BDI scores. Each group is divided into 2 subgroups again. After instrumentation and 10-minutes rest period, mental stress by operation was provided for 15-minutes. HRV was recorded before and after the mental stress. Then the control groups rested for 15-minutes. The experimental groups were treated with Aromatherapy. And then HRV was recorded. Results : 1. There were no significant differences in the mean HRT and SDNN between each group. 2. LF, HF, and LF norm showed different changes in each group. 3. LF/HF ratio showed significant changes. Conclusions : These results suggest that psychic factor makes an important rule under the mental stress and the effect of Aromatherapy, and Aromatherapy is effective to recover mental stress.

This paper proposes the method to develop information system for maintenance of urban transit. We have to develop the standard information system, but have difficult to get user"s requirement. To solve this problem, we propose the method, web-based, component-based, and prototype-based development method. Proposed method may provide a procedure to develop information system that have hard to get user"s requirement.

Most surveillance systems of urban transit are based on CCTV(Closed Circuit Television). However, there is limitation that the passive monitoring system using CCTV in urban transit surveillance system to monitor massive environment applies thousands of cameras and it depends on operator's instinctive judgement whether it happens an accident or disaster. Urban transit operation corporations try to introduce the intelligent technology to overcome these problems as mentioned above. The intelligent system can be organized various ways and made configuration for purpose and function. In this paper, we describe the configuration problems of the existing surveillance system and propose the proper intelligent system configuration for urban transit. We expect that the proposed configurations are very helpful to introduce the intelligent technology for urban transit surveillance system.

This paper is intended to provide a method to design control software for the TCMS, train control and monitoring system. The TCMS with this control software will be applied KOREA Standard EMU. The control software is designed by SCADE Case tool to concern safety and reliability. The function for the EMU is implemented in software easily programmed, using a functional block, graphic programming language. The control software has modular design and each module is tested with SCADE simulator. This time we focus a door control module, present a design method and a simulation method for that module.

Most recognition algorithms for intelligent surveillance system are based on analysis of the video collected from one camera. Video analysis is also used to compute the internal parameters used in the recognition process. The algorithm computes only the video of the fixed area so that it is a insufficient method and it could not use information of the related areas. However, intelligent integrated surveillance system should be constructed to correlate the events in the other areas as well as in the fixed area. In this paper, in order to construct the intelligent integrated surveillance system, we describe the method not to focus on the video of each camera but to aware the whole event by sharing information between cameras, which is more accurate. The method would be used to aware the event in the fixed area such as stations in urban transit.

Service areas in the urban transit need to construct the intelligent integrated surveillance system, because they are the public places that many people get together at one time. In past, analogue, closed-circuit televisions and analogue video recorders are used to construct the surveillance system. Now, a lot parts of the analogue systems that depend on the images have been changed to the complicated system, which consists of sensors and images and also, to be digitalized. In past, the surveillance system was used as an inspection devices to examine the spots after happening some events. But, with a high level of the computer and communication technologies, it is possible that the digitalized data leads the intelligence systems to prevent some accidents by using the various analysis techniques. And the data could be used to decide surveillance policies and provide some information on the safety and management policies as well as surveillance policies. In this paper, we define the intelligent surveillance system and suggest the major functions of the system. Also, we suggest the fundamental functions that every part should get and describe the way to develop the system.
