Research has shown that many smokers experience an increase in the desire to smoke when exposed to smoking-related cues. Cue exposure treatment (CET) refers to the manualized, repeated exposure to smoking-related cues, aimed at the reducing cue reactivity by extinction. In this study, we constructed a virtual reality system for evoking a desire of nicotine, which was based on the results of a Questionnaire of Nicotine-craving. And we investigated the effectiveness of the virtual reality system as compared to classical device (pictures). As a result, we reached the conclusion that virtual reality elicits more craving symptoms than the classical devices.

This paper aims to study that the defect exploration method to specimen's thickness, using an characteristic of an ultrasonic wave generating in ablation area and thermo elasticity area, has been applied to using a way of receiving it by Air-Coupled Transducer and transmitting it by an ultrasonic wave and a way of noncontact receiving and transmitting ultrasonic wave using a laser. The longitudinal, transverse waves have been used in 60㎜ thickness specimen and Lamb wave in 3㎜ to run artificial defect detection test. In this way, the usefulness of noncontact laser ultrasonic wave has been verified. To confirm the possibility of implementation on natural defect existing at real welding part, thickness in 3㎜ SM45C and STS304 artificial defect specimen has been made and defect detection test using Lamb wave has been executed. Detected signal by signal treatment has been expressed in visual not RF signal. By doing so the convenience of defect detection has been attempted and the effectiveness of defect signal visualization using Lamb wave has been confirmed compare with defect image through SAT.

In this study, researchers developing the estimative algorithm for artificial defects in semiconductor packages and performing it by pattern recognition technology. For this purpose, the estimative algorithm was included that researchers made software with MATLAB. The software consists of some procedures including ultrasonic image acquisition, equalization filtering, Self-Organizing Map and Backpropagation Neural Network. Self-Organizing Map and Backpropagation Neural Network are belong to methods of Neural Networks. And the pattern recognition technology has applied to classify three kinds of detective patterns in semiconductor packages : Crack, Delamination and Normal. According to the results, it was found that estimative algorithm was provided the recognition rates of 75.7% (for Crack) and 83.4% (for Delamination) and 87.2% (for Normal).

In process for production of Rubber Scheme Product that have the most inferior Working Environment is Medicine mixture and Scheme processing. Applying automation and Environment Treatment technology to the hazardous chemical and mixture processing, Through developed ’Mixture Automatic Machine for hazardous chemical Interruption type that is occurred at mixing rubber medicines’, we try to decline worker’s intensity of labour. Also, overcomes solution of work evasion phenomenon and manpower supply and demand’s difficulty by forming agreeable working environment and through the automatic scheme and mixture processing by preventing that hazardous chemical had known as disease causes of various importance disease is exposed to worker during the work. and we plan to do so that production of high added value product may be available.
