  • In speech recognition, confidence measuring is to decide whether it can be accepted as the recognized results or not. The confidence is measured by integrating frames into phone and word level. In case of word recognition, the confidence measuring verifies the results of recognition and Out-Of-Vocabulary (OOV). Therefore, the post-processing could improve the performance of recognizer without accepting it as a recognition error. In this paper, we measure the confidence modifying log likelihood ratio (LLR) which was the previous confidence measuring. It accumulates only those which the log likelihood ratio is negative when integrating the confidence to phone level from frame level. When comparing the verification performance for the results of word recognizer with the previous method, the FAR (False Acceptance Ratio) is decreased about 3.49% for the OOV and 15.25% for the recognition error when CAR (Correct Acceptance Ratio) is about 90%.

  • This study conducted a survey targeting 414 medical institution workers to identify the impacts of their emotional labor and the recognition level of medical service fee reduction influencing the reduction rate. The results were as follows. First, a review of the difference in the reduction rate by socio-demographic characteristics revealed that in both inpatient and outpatient reduction rate, there is a significant difference in the occupational description, working history at the current hospital, and the numbers of approved beds. Second, there is a correlation between emotional labor, the recognition level of medical service fee reduction, and the reduction rate. As a result of the analysis, there is a significant positive correlation between emotional labor and outpatient reduction rate, a significant negative correlation between the recognition level of medical service fee reduction and inpatient reduction rate, and a significant negative correlation between the recognition level of medical service fee reduction and outpatient reduction rate. Third, emotional labor has a significant positive effect on the inpatient reduction rate, and the recognition level of the medical service fee reduction has a negative effect on the inpatient reduction rate. The emotional labor also has a significant positive effect on outpatient reduction rate, and the recognition level of the medical service fee reduction has a significant negative effect on outpatient reduction rate.

  • Purpose: This study was to the investigate recognition of physical activity between physical therapy students (PTS) and non-physical therapy students (NPTS) by measuring the level of physical activity using International Physical Activity Questionnaires (IPAQ). Methods: A cross-sectional survey was completed by 191 university students. The IPAQ with an additional question (Is physical activity necessary for your future job?) was used to evaluate the recognition and the amount of physical activity. The collected data were calculated as MET-minutes scores and were classified as walking, moderate, and vigorous level of physical activity. The students were analyzed by dividing them into those who had a part-time employment (16 PTS and 12 NPTS) and those who did not have a part-time employment (80 PTS and 83 NPTS). Results: In students with a part-time employment, no significances were observed between the PTS and NPTS, in terms of MET, frequency and time of physical activity, and sitting time (p>0.05). In students without a part-time employment, the NPTS was significantly higher than the PTS for the MET and frequency of physical activity in a vigorous level (p<0.05), and there were no significant differences in other levels of physical activity (p>0.05). In the additional question, the PTS showed a slightly higher than the NPTS (p<0.05). Conclusion: The physical therapy students did not remarkable barrier to recognition of physical activity, but there was a difference in their recognition of the vigorous level of physical activity. Therefore, the understanding of physical activity for PTS would play an important role in the recognition of how physical activity can be promoted.

  • Recently, continuous dimensional emotion recognition from audiovisual clues has attracted increasing attention in both theory and in practice. The large amount of data involved in the recognition processing decreases the efficiency of most bimodal information fusion algorithms. A novel algorithm, namely the incomplete Cholesky decomposition based kernel cross factor analysis (ICDKCFA), is presented and employed for continuous dimensional audiovisual emotion recognition, in this paper. After the ICDKCFA feature transformation, two basic fusion strategies, namely feature-level fusion and decision-level fusion, are explored to combine the transformed visual and audio features for emotion recognition. Finally, extensive experiments are conducted to evaluate the ICDKCFA approach on the AVEC 2016 Multimodal Affect Recognition Sub-Challenge dataset. The experimental results show that the ICDKCFA method has a higher speed than the original kernel cross factor analysis with the comparable performance. Moreover, the ICDKCFA method achieves a better performance than other common information fusion methods, such as the Canonical correlation analysis, kernel canonical correlation analysis and cross-modal factor analysis based fusion methods.

  • In this paper, a problem of Thai sign language recognition using a neural network is considered. The paper addresses the problem in classifying certain signs conveying quantitative meaning, e.g., large or small. By treating those signs corresponding to different quantities as derived from different classes, the recognition error rate of the standard multi-layer Perceptron increases if the precision in recognizing different quantities is increased. This is due the fact that, to increase the quantitative recognition precision of those signs, the number of (increasingly similar) classes must also be increased. This leads to an increase in false classification. The problem is due to misinterpreting the amount of quantity the quantitative signs convey. In this paper, instead of treating those signs conveying quantitative attribute of the same quantity type (such as 'size' or 'amount') as derived from different classes, here they are considered instances of the same class. Those signs of the same quantity type are then further divided into different subclasses according to the level of quantity each sign is associated with. By using this two-level classification, false classification among main gesture classes is made independent to the level of precision needed in recognizing different quantitative levels. Moreover, precision of quantitative level classification can be made higher during the recognition phase, as compared to that used in the training phase. A standard multi-layer Perceptron with a back propagation learning algorithm was adapted in the study to implement this two-level classification of quantitative gesture signs. Experimental results obtained using an electronic glove measurement of hand postures are included.

  • This paper studies on the recognition rate change with respect to illumination variance and the confidence level of PCA(Principal Component Analysis) based face recognition by measuring the cumulative match score of CMC(Cumulative Match Characteristic). We studied on the confidence level of the algorithm under illumination changes and selection of training images not only by testing multiple training images per person with illumination variance and single training image and but also by changing the illumination conditions of testing images. The experiment shows that the recognition rate drops for multiple training image case compared to single training image case. We, however, confirmed the confidence level of the algorithm under illumination variance by the fact that the training image which corresponds to the identity of testing image belongs to upper similarity lists regardless of illumination changes and the number of training images.

Methods : 900 households(a 1% sample) were randomly selected from the total population of K city located in Kangwon province. An interview survey was performed with using a structured questionnaire for the subjects(923 persons) who had used medical service during the year before the survey, and the survey was done September, 2002. Results : When comparing the relating factors related with customer royalty according to the sociodemographic characteristics, the older group showed a significantly higher level of recognition for service quality, service reputation, internal customers' attitudes and switching cost. The lower income group showed a higher level of recognition for service quality, service image and switching cost. The lower educated group showed a higher level of recognition for service reputation, service image and internal customers' attitudes. The higher educated group showed a higher level of recognition for perceived risk, and seeking variety. In addition, the expert group or the service and manufacturing workers group showed a higher level of recognition for service involvement. On multiple regression analysis, internal customers' attitudes, service image, service reputation, service quality, switching cost, and substitutability showed significant relations with customer loyalty. Conclusions : This study showed that customer loyalty was significantly influenced by service factors like internal customers' attitudes, service image, service reputation, and service quality, and by market factors like switching cost, and substitutability. The results of this study can be used as a baseline for developing strategies to create and keep customers with high loyalty.

  • Purpose: The purpose of this study was to describe nurses' recognition of, and practice level in management of general nosocomial infections, and methicillin resistant staphylococcus aureus (MRSA) and vancomycin resistant enterococci (VRE) infections. Method: A self-administered questionnaire was used to collect data. Data were collected on June, 2003 from 190 nurses in one university affiliated hospital located in Suwon. Result: The mean score for nurses' recognition of general nosocomial infection control was 3.57, MRSA control was 3.54, and VRE control was 3.86. The mean score on practice for control of general nosocomial infection was 3.19, for MRSA control, 3.20, and for VRE control, 3.63. There were statistically significant relationships between the recognition level and practice level for general nosocomial, MRSA, and VRE infection control. According to the general characteristics of the nurses, the mean scores for both recognition and practice were higher for those nurses who had had infection control education, for those who had worked longer in nursing, and for those who worked in the ICU. Conclusion: It is suggested that appropriate hospital infection control programs should be developed through continuous education and practice to improve nurses' level of the practice in general infection control, and especially in MRSA and VRE infection control.
