This paper has investigated the effects of employees' organizational cynicism on their organizational commitment and pro-union behavioral intentions in the context of repetitively implementing business innovation program. The cynical responses about the business innovation program & projects have been classified into four categories; Exit, Voice, Loyalty and Neglect. The research samples have been drawn from managers and office employees at four business sites of conglomerates in Korea. According to the analysis, business innovation program which is continuous and repetitive has made managers and office employees have highly cynical attitudes. In turn, the organizational cynicism has accelerated their Exit and Neglect responses, but shrunk Voice and Loyalty responses. As a result, it has been confirmed that the organizational cynicism has a direct effect on organizational commitment and pro-union behavioral intentions. In addition, it has been concluded that Exit and Neglect had a negative effect on organizational commitment but a positive effect on pro-union behavioral intentions. Even though Voice and Loyalty had a positive effect on organizational commitment, they had no significant effect on pro-union behavioral intentions. Furthermore, no mediating effect has been detected. Implications and suggestions for future research were then discussed.

This study examined the effect of vocal loudness on nasalance measures, under the conditions of three sentence patterns (i.e., Oral sentences, Mixed sentences, Nasal sentences). The vocal loudness level was classified into soft voice (55 dB), medium voice (65 dB) and loud voice (75 dB). The participants in the present study were 30 normal adults (male: female =1:1). Kay's Nasometer 6200 was used to measure nasalance and Sound level meter was used to adjust the loudness level. The results of the present study are as follows. Firstly, the change in vocal loudness is in the following. In the Oral sentence stimuli, the loud voice for both male and female showed the highest nasalance degree, and the medium voice the lowest level. In the Mixed and Nasal sentence stimuli, however, male participants showed the highest degree of nasalance in the soft voice, and the lowest degree in the loud voice, and female showed the highest degree of nasalance in the soft voice and the lowest in the medium voice. Secondly, when each subject's nasalance scores were ranked in a ordered manner, noticeable tendency. Lowest nasalance score occurred in the loud voice and the highest nasalance score was recorded in the soft voice during participants' reading of the Nasal sentences. However, it was hard to find such pattern in the Oral sentences. It is assumed that velopharyngeal function could be related to these findings. Furthermore, the findings associated with vocal loudness may have diagnostic as well as clinical implications.

Voice service is very demanding in cognitive radio networks (CRNs). The available spectrum in a CRN for CR users varies owing to the presence of licensed users. On the other hand, voice packets are delay sensitive and can tolerate a limited amount of delay. This makes the support of voice traffic in a CRN a complicated task that can be achieved by devising necessary considerations regarding the various network functionalities. In this paper, the support of secondary voice users in a CRN is investigated. First, a novel packet scheduling scheme that can provide the required quality of service (QoS) to voice users is proposed. The proposed scheme utilizes the maximum packet transmission rate for secondary voice users by assigning each secondary user the channel with the best level of quality. Furthermore, an analytical framework developed for a performance analysis of the system, is described in which the effect of erroneous spectrum sensing on the performance of secondary voice users is also taken into account. The QoS parameters of secondary voice users, which were obtained analytically, are also detailed. The analytical results were verified through the simulation, and will provide helpful insight in supporting voice services in a CRN.

The purpose of this study was to investigate the reason why puberphonia patients revisit hospitals after completion of its treatment and the effect of visual voice therapy on voice improvement. The subject the study included are two puberphonia patients who had been diagnosed by laryngologists. The patients who were diagnosed as puberphonia by the laryngologist and treated by the a speech pathologist, completed their treatment and revisited hospital. The study used laryngoscopy, acoustic and aerodynamic analysis before and after voice treatment to investigate what change happens and why generalization of treatment effect did not occur naturally in the daily life. Their voices of pre-therapy and post-therapy were analyzed on the aspects of acoustics, aerodynamics and laryngeal endoscopy. As a result, it was found that fundamental frequency(Fo) was significantly lowered in respect of acoustic change and maximum phonation time(MPT) was increased to some extent in respect of aerodynamic change. In addition, there was a laryngoscopic change and commissure glottic chink disappeared generally in the phonation. The reason why the generalization did not occur naturally in one’s daily routine was mainly due to the fact that high-pitched voicing was used for a long time. Other than that reason, negative reaction or attitude of surrounding people and lack of confidence were to blame for failure of generalization.

Vocal nodule is one of the representative chronic diseases of vocal folds, and it can be cured by surgical removal or voice therapy. The aim of this study is to evaluate the effect of the accent method, one of the popular effective voice therapy, in the patients with vocal nodule. Authors executed the accent method in 17 patients with vocal nodule who visited the Voice & Speech Therapy Clinic, Pusan National University Hospital analysed the voice before and after treatment using the local findings, acoustic analysis and aerodynamic analysis MPT. The voice was analysed with MDVP of CSL and MPT was checked using stop watch. The parameters included Fo, Jitter, Shimmer and noise to harmonic ratio(NHR) as acoustic analysis. The results were obtained as follows. In the evaluation by the local findings, it was improved to 77% in the patients of vocal nodule. Jitter and Shimmer were shown to be improved significantly. In particular, it was shown to be improved significantly in patients with vocal nodule. As the result of this study, the improvement of aerodynamic aspect was more statistically significant than that of acoustic parameters. When I generalized the above mentioned results, we suggest that it is a useful voice therapy which can be helpful to the improvement of voice, applying the accent method to the vocal nodule patients, and there are currently many methods to be used in the voice therapy, but it is thought which the accent method is the good treatment as the alternatives of keeping the continuous medical treatment.

This study investigates the effect of voice quality on speech intelligibility and the relationship between voice quality and intelligibility for children with spastic CP. We recruited 36 children with spastic CP (mean age 10.43 year, 17 girls, 19 boys, spastic type 34, mixed 2) from a special school and a rehabilitation hospital. Voice samples for the perceptual analysis of voice quality were extracted from a sustained vowel /a/ and were rated on the GRBAS scales by two experienced speech language pathologists. Ten adult subjects with no hearing problems evaluated speech intelligibility for the 37 words listed in the Assessment of Phonology and Articulation for Children on a 7-point interval scale. The children with spastic CP were divided into three groups according to the rated G scores on the GRBAS scales (G1(n)=10, G2(n)=13, G3(n)=13). Analyses of ANCOVA and Pearson correlation showed that there was a significant difference in speech intelligibility among three groups. There was also a significant correlation in G scale (grade), A scale (asthenia), B scale (breathy) score, and speech intelligibility. These findings suggest that poor speech intelligibility of spastic CP might be related to asthenia and breathiness. Vocal intensity should be increased and vocal functioning should be improved for speech therapy to improve speech intelligibility of the children with spastic CP.

Purpose: The application of IoT is finding continuous acceptance in our daily lives, particularly, smart speakers are making life easier and convenient for consumers. This research aims to develop and test an integrated model of factors influencing consumer's adoption of voice-enabled IoT devices. Design/methodology/approach: Based on the VAM, an integrated voice-enabled IoT device adoption model is proposed. Gender differences on five constructs relating with perceived value (perceived usefulness, perceived enjoyment, perceived security risk, perceived technicality and perceived cost) was also examined through PLS-MGA technique. The usage experience of consumers was also controlled in the integrated VAM. Findings: Result shows that Perceived-Usefulness, Perceived-Enjoyment and Perceived-Cost have a strong effect on Perceived-Value. However, Perceived-Technicality and Perceived-Security-Risk are non-influential and have no significant effect on PV. Additionally, Perceived-Value and Social-Influence plays a significant role in predicting adoption intention. Gender differences also exist in consumers perception of usefulness, enjoyment and cost. In comparison to the basic value-based adoption model, the integrated model provides more insight on consumers adoption of voice-enabled IoT devices. Originality/value: Using an integrated model, this study is one of the first scholarly attempt at modelling the influential factors for adopting smart speakers i.e., voice-enabled IoT devices, with implications for improved adoption.

Background and Objectives : Vocal nodule is common inflammatory vocal cord lesion which could be improved by voice rest or voice therapy. But some patients, who do not have any improvement after voice therapy, should take laryngomicorsurgery or additional long-term voice therapy. So we try to find prognostic factors which affect the results of voice therapy. Materials and Methods: There are 36 patients (response group) whose symptoms improved after initial voice therapy and 16 patients (no response group) whose symptoms did not improve at all. We compared clinical features (durations of symptoms, voice abuse, laryngopharyngeal reflux), GRBAS scale, acoustic analysis, aerodynamic analysis and voice handicap index between the two groups from January, 2006 to June, 2008. Results: Response group underwent voice therapy 4.5 times (ave.) and no response group underwent 6.7 times (ave.). No response group has longer duration of symptoms, higher GRBAS scale score, higher NIH ratio, and higher MFR than those of response group. Conclusion : This study found that the prognosis of voice therapy in patients who have longer duration of symptoms, high NIH ratio, and bad perceptional test result is not likely to be good. In those cases, we should recommend earlier surgery, voice therapy after surgery, and inform about the necessity of long-term voice rehabilitation or voice therapy in order to get favorable compliance.

Purpose - This study investigated the effect of paternalistic leadership on Chinese employees' creative work involvement. In addition, it also examined the mediating effects of group cohesiveness and employees' voice behavior in the above relationship. Design/methodology/approach - Based on survey data from 452 employees working in Chinese firms, empirical analysis was conducted by using hierarchical regression model. Findings - As a result, it was found that the authoritative of paternalistic leadership had a negative effect on employees' creative work involvement, and the moral and compassion of paternalistic leadership have a positive effect on employees' creative work involvement. Second, we found that loneliness had a positive mediate effect in the relationship between the paternalistic leadership and employees' creative work involvement. Research implications or Originality - This paper confirmed the paternalistic leadership still has an important impact on the creativity of Chinese employees, making up for the lack of previous literatures. In addition, it was confirmed that group cohesiveness and voice behavior play an important mediating role between paternalistic leadership and employees' creative work involvement. We also discuss important theoretical and practical implications of these findings.
