Recently, audio-visual speech recognition (AVSR) has been studied to cope with noise problems in speech recognition. In this paper we propose a novel method of deciding weighting factors for audio-visual information fusion. We adopt the particle swarm optimization (PSO) to weighting factor determination. The AVSR experiments show that PSO-based normalized confidence measures (NCM) improve the rejection performance of mis-recognized words by 33%.

In this paper, a method to cope with short-term blackout is proposed. The proposed method uses a capacitor bank consisting of supercapacitors. A supercapacitor is a good means for short-term energy storage. The proposed circuit is simple and accordingly easy to construct and to control. A prototype is constructed and experimental results are presented.

Along with the international technology transfer market, as the domestic market grows, more professional technology analysts are needed and it became more necessary to investigate the qualification of those experts to cope with growing market. In this study, the current working condition of those experts is described, qualification system is analyzed and more realistic suggestions on the system to activate the market and to encourage the experts will be introduced. The study was performed based on the questionnaire sent to the person who works in related fields, such as industry, technology transfer center, universities, etc.

Surveying and GIS have increasingly contributed to improve the quality of humane life through the development of its technology. While the surveying professions are now experiencing the crisis of identity. In this paper, we aim to study the concepts and presence of newly used terminologies, present state and future vision of surveying and GIS in Korea. To cope with various surveying consumers for expanding the market and their demands, enhancement of educational system, complement of laws legal system, construction of cooperative system in business are basically required.

Cognitive-behavioral approach to two cases with chronic headache was presented. Cognitive-behavioral interventions focus on indirectly altering symptom-related physiological activity by changing the way patients cope with headache-eliciting stressors. This treatment focuses directly on the patients' cognitive and behavioral changes. Cognitive-behavioral treatment can be divided into three phases Education, self-monitoring, and problem-solving or coping-skills training. Literature reviews on the follow-up evaluation of therapeutic effectiveness revealed that cognitive-behavioral treatment is effective in the management of chronic headache.

This paper presents an image processing technique to get traffic information such as vehicle volume, velocity, and occupancy for measuring the traffic congestion rate. To obtain these information, two horizontal lines are previously set on the screen. A moving vehicle is detected using the gray level difference on each line, and also template matching method at night. Threshold values are determined by sampling pavement grey level, and updated dynamically to cope with the change of ambient light conditions. These technique is successfully used to calculate vehicle volume, occupancy, and velocity. This study can be applied to traffic signal control system for minimizing traffic congestion in urban areas.

The environment of the access network service market is characterized by uncertain demand and various competing alternative technologies. In Korea, despite the introduction of competition, dominant Public Network Operator(PNO) still leads the market. Therefore, the decision of PNO has a great impact on the access network evolution. In this paper, we propose an model which aims to reduce risks and both investment and operating costs, to cope with the uncertain demand and technology evolution. We expect this model to provide a tool analyze risks and evaluate various strategies on the network evolution.

In this paper, the elemental components and improving purpose in advanced safety management system are reviewed to cope with a railway fire accident. And a considering procedure(V-cycle) of long-term plan for railway fire safety improvement is proposed. For the purpose of preventing recurrence of accident, items which have to be considered in the course of accident investigation and cause analysis are presented according to the stage of investigation activity.
