In this paper, we describe the implementation of a microphone input level control algorithm and the speech improvement with this level controller in personal computer environment. The volume of speech obtained through a microphone affects the speech recognition rate directly. Therefore, proper input volume level control is desired fur better recognition. We considered some conditions for the successful volume controller implementation firstly, then checked its usefulness on our speech recognition system with common office environment speech database. Cepstral mean subtraction is also utilized far the channel-effect compensation of the database. Our implemented controller achieved approximately 50% reduction, i.e., improvement in speech recognition error rate.

Background & Objectives: This study investigates the recognition on the necessity of the use of radiation for both college students who are considered that they have a high knowledge level in radiation and proposes basic materials to change the recognition of the use of radiation. Also, the investigation was applied to average people who showed the most negative attitudes on radiation. Methods: A questionnaire was applied to 600 college students for five days from October 10 to 15, 2005 and used in statistical analysis. Results: The average value obtained in the recognition of the use of radiation was 76.60 points in which male respondents who were majored in natural science, health, and engineering department and respondents who have experienced radiation related education, radiation diagnosis, and radiation treatment demonstrated higher levels. Also, the average value obtained in the recognition of the radiation damage was 71.66 points in which respondents who were majored in natural sciences, humanities, engineering, and health department showed higher levels than that of respondents who were majored in art and physical department. Groups that exhibited higher recognition levels in the necessity of the use of radiation were male respondents and respondents who were majored in natural science, humanities, and health department and have experienced radiation diagnosis and radiation treatment. In the results of the correlation analysis on the necessity of the use of radiation and recognition of radiation damages, the recognition of radiation damages was presented as negative attitudes in the case of the higher recognition level in the necessity of the use of radiation. Conclusions: Regarding the frequency of the use of radiation in Korea, a 80.9% of university students who showed a high education level had no experiences in radiation related education. Although they showed a relatively high level of 76.6 points in the recognition level of the necessity of the use of radiation, the negative attitude on the radiation damage was also presented as a high level of 71.7 points. Because the providing chance of radiation related information was limited as compared to the atomic power used in Korea and dependancy of the use of radiation, it is necessary to provide the basic information related in the use of radiation to the public. In addition, various investigations on the use of radiation and such negative attitudes are required in future for the public. Also, the correct information of the radiation safety should be delivered to the public.

Vehicle license plate recognition system is not generalized in Malaysia due to the loose character layout rule and the varying number of characters as well as the mixed capital English characters and italic English words. Because the italic English word is hard to segmentation, a separate method is required to recognize in Malaysian license plate. In this paper, we propose a mixed character level and word level English license plate recognition algorithm using deep learning neural networks. The difference of Gaussian method is used to segment character and word by generating a black and white image with emphasized character strokes and separated touching characters. The proposed deep learning neural networks are implemented on the LPR system at the gate of a building in Kuala-Lumpur for the collection of database and the evaluation of algorithm performance. The evaluation results show that the proposed Malaysian English LPR can be used in commercial market with 98.01% accuracy.

Rheumatoid arthritis as one of the chronic illness requiring management in long period of time puts great burden to patients, their family and society. For patients with chronic illnesses, providing a social support is important and the most important source comes from spouses. Therefore we assessed burden of husbands of female rheumatoid arthritic patients and also found out the factors affecting burden. The sample of study was 107 female rheumatoid arthritic patients and their spouses. The tool of assessing spouses' burden was the revised version of subjective and objective parameters developed by Montgomery et al.(1985). The results are as follows: 1. General characteristics of patients and spouses: The mean age of the patients was 48 years. Educational level of patients was high school 41.1%. The mean age of the spouses was 51years. Educational level of spouses was mostly high school(40.2%) and college(29.9%) graduate. The mean marital period was 23.4years. Average income per month was 1,609,000 won. The average duration since diagnosis was 9.4years. As a therapy, 67.3% chose standard drug therapy. Average rating of discomfort by patient was 3.05(range 1-5) and that of severity was 3.48 and that of dependency was 2.58. The husband's rating of their spouses disease severity was 3.68. 2. Husbands' burden: The average burden in subjective items was 21.61(range 6-36) and objective items was 35.24(range 10-60). The average of total burden was 56.59(range 16-96). 3. Husband's total burden correlated with patient's age, educational level of patients, therapy method, patient's level of discomfort, patient's severity, patient's level of dependence, husband's recognition of level of severity in statistical level. Husband's objective burden correlated with patient's age, educational level of patient, patient's level of discomfort, husband's recognition of level of severity. Husband's subjective burden correlated with patient's age, educational level of patients, therapy method, patient's severity, patient's level of dependence, husband's recognition of level of severity. 4. Linear correlation analysis on burden: The husbands' total burden is explained in 37 7% by husband's recognition of level of severity and husband's age. The husbands' objective burden is explained in 31.2% by patient's level of dependence, husband's age, husband's recognition of level of severity. The husbands' subjective burden is explained in 26.7% by husband's recognition of level of severity and patient's age. In conclusion, husbands' level of burden is affected by many factors and therefore nursing strategy for relieving burden of middle aged husbands should be individualized taking these factors into consideration.

Objectives : The oral health education for interaction between snack and oral health is made more in detail, it seems to contribute to improvement of oral health by reducing occurrence of dental caries. Methods : This study performed the survey for 530 high school and college students living in Y City, Chungbuk for 10 days from June 14, 2011 to understand the difference by the level of snack recognition. 530 copies of questionnaire were collected, the final 502 copies were analyzed and the results are as followings. Results : 1. As for the snack intake frequency, 'sometimes' and '2~3 times a day' was found to be largest with 32.0% respectively in female and 'sometimes' was largest with 34.9% in male. As for the '2~3 times a day' was most in high school students with 31.5% and 'sometimes' was most in college students with 39.0%. 2. As for snack characteristics, 'crispy' was most preferred in female and male with 43.7% and 39.4% respectively and, by school year, high school students and college students preferred 'crispy' most with 39.1% and 46.0% respectively. 3. As for the item of meal, 'sometimes skip' was most in female with 46.1% and 'all three meals a day' was most im male with 51.4%. 'All three meals a day' was proved to be most with 48.3%in high school students and 'sometime skip' was most in college students with 48.0%. 4. As for the difference of oral health management by school year, college students ($3.37{\pm}0.70$) proved to be higher in the oral health management (p<.01) than high school students ($2.98{\pm}0.81$) and the Negative snack recognition group ($3.24{\pm}0.73$) was found to be higher in the oral health management (p<.01) than the Positive snack recognition group ($3.06{\pm}0.82$). Although the interaction between school year and snack recognition level was not different in case of college students, the Negative snack recognition($3.17{\pm}0.77$) proved to manage higher oral health (p<.05) than the high snack recognition gathering ($2.81{\pm}0.80$) in case of high school students. 5. As for the difference of the oral health most im male wex and). Although the innteractifemale ($3.39{\pm}0.72$) proved to most the oral health (2.(p<.01) than male ($2.81{\pm}0.75$) and the group with Negative snack recognition terac ($3.24{\pm}0.73$) most d the oral health (2.(p<.01) than the group with Positive snack recognition level ($3.06{\pm}0.82$). As for effects of interaction between sex and snack recognition level, while there was not much difference in the oral health management by the snack recognition level in case of female, the cluster of low snack recognition level ($3.03{\pm}0.69$) proved to manage the oral health more (p<.01) than the gathering of high snack recognition level ($2.59{\pm}0.75$). Conclusions : To see the results as above, it can be seen the oral health management is higher as the snack recognition level is higher by sex and school year.

For speech recognition systems, rejection function as well as decoding function is necessary to improve the reliability. There have been many research efforts on out-of-vocabulary word rejection, however, little attention has been paid on non-target sentence rejection. Recently pronunciation approaches using speech recognition increase the need for non-target sentence rejection to provide more accurate and robust results. In this paper, we proposed filler model method and word/phoneme detection ratio method to implement non-target sentence rejection system. We made performance evaluation of filler model along to word-level, phoneme-level, and sentence-level filler models respectively. We also perform the similar experiment using word-level and phoneme-level word/phoneme detection ratio method. For the performance evaluation, the minimized average of FAR and FRR is used for comparing the effectiveness of each method along with the number of words of given sentences. From the experimental results, we got to know that word-level method outperforms the other methods, and word-level filler mode shows slightly better results than that of word detection ratio method.

The study begins with the proposition that customers' recognition of risk and their information level for a service firm and its product influence to the selection of information channel and loyalty of customers. Experimental study found that the likelihood of personal information channel selection would be increased as customers felt higher level of risk and as they had lower level of information when they purchased service products. The study also found that customer loyalty would be influenced by the risk recognition level, but the relationship between loyalty and information level was not significant.
