In this paper, it is proposed the management items for voice traffic using CDRs so that global carriers can treat and manage the voice traffic for a customer, and defined computational expressions to produce the management items. From them, we have designed the management system, which is composed of web interface module, analysis module, data collection module and database management module, and have improved the availability and convenience of the system using web technologies. In addition, we have tested these items using CDRs in real environments that are collected by the global carrier in order to verify their validity. It is expected that the proposed web based voice traffic management system provide a global carrier with network information collection, fault detection/trouble-shooting and high quality of service through analyzing the characteristics of subscribers.

This study investigated if there are differences between Korean and Chinese consumers among the determinants of consumer complaint intention, type of complaint intention, and traits of complaining behavior. Sample subjects used in this study were female college students in Jeollabukdo and Jeollanamdo, Korea and Yunnam, China. Questionnaire data from 780 college students(Korea: 441, China: 339) were analyzed through a reliability analysis, factor analysis, frequence, mean, and multiple regression analysis. The results of the study were as follows. First, complaint intention of college students was divided into 3 factors, voice, private, and third party. Second, the findings of regression analysis for the total sample showed that the determinants of the factor 'voice' were the country, salespeople, product involvement, complaint cost, psychological tension, and social benefit. Whereas, the determinants of the factor 'private' were the producer, product involvement, psychological tension, and social benefit. Also, the determinants of the factor 'third party' were the country, oneself, salespeople, complaint cost, personal norms, and social benefit. Third, significant differences were indicated in the determinants of the 'voice', 'private' and 'third party' factors of complaint intention between Korean and Chinese consumers. Fourth, the complaint intention factors of 'voice' and 'third party' of Chinese consumers were higher than Korean consumers. Fifth, the attributions to dissatisfaction of Korean consumers were higher than Chinese consumers, and the product involvement, possibility for success, and consumer complaint attitudes of Chinese consumers were revealed to be higher than Korean consumers.

The purpose of this study is to provide basic data for human resource management and efficient hospital management of organization by checking the effect of psychological contract of nurses on voice behavior. It is a descriptive research study that survey nurses who consented responded to the research questions. As a result, nurse practitioners showed a low level of perceptions of organizational commitment, psychological contracts, transactional contract and relational contract. There was a positive correlation between transactional contract and constructive voice(p<.05), and there was a negative correlation between relational contract and destructive voice(p<.05). Therefore, it is necessary to establish a system in which internal and external compensation can be made according to changes in roles of nurses in order to carry out new polices and organizational changes. It is also necessary to improve the organizational culture so that nurses can actively participate in policy and organizational change.

Background and Objectives : It has been pointed out that alcohol intake in human beings induces changes in voice register and maximum phonation time. These changes supposedly result from injection of the vibratory vocal folds. The purpose of this study was to clarify the voice changes associated with alcohol intake and the changes of laryngeal mucosa. Materials and Methods : The subjects included 29 volunteers, including 20 men and 9 women ranging in age from 22 to 31 years. Alcohol intake was accomplished by oral administration of 23% soju 1 bottle (255cc). Serum alcohol concentration levels were evaluated hourly for 3 h after ingestion of alcohol. Seven measurements were performed at pre-alcohol intake and post-alcohol intake hourly : fundamental frequency, jitter, shimmer, noise to harmonic ratio as the acoustic analysis, maximal phonation time, mean flow rate, and subglottal pressure as the aerodynamic analysis. The changes of laryngeal mucosa were evaluated by flexible laryngoscope at each measurement. Results : By comparing the acoustic and aerodynamic data and laryngeal mucosa before and after alcohol intake, there were not remarkable changes (p>0.05). Conclusion : The voice and laryngeal mucosa have not remarkably changed according to alcohol concentration in this study. Furthermore studies on the voice change induced by multiple alcohol concentrations are required.

This study aimed to investigate the clinical utility of voiced sentence tasks for voice evaluation. To this end, we analyzed the correlation between perturbation-based acoustic measurements [jitter percent (jitter), shimmer percent (shimmer), Noise to Harmonic Ratio (NHR)] using sustained vowel phonation, and cepstrum-based acoustic measurements [Cepstral Peak Prominence (CPP), Low/High spectral ratio (L/H ratio)] using voiced sentences. As a result of analyzing data collected from 65 patients with voice disorders, there was a significant correlation between the CPP and jitter (r = -.624, p = .000), shimmer (r = -.530, p = .000), NHR (r = -.469, p = .000).This suggests that the cepstrum measurement of voiced sentences can be used as an alternative to the analysis limitations of the pathological voice such as not possible perturbation-based acoustic measurement, and result difference according to the analysis section.
