  • For reappearance of driving perception in a driving simulator, a washout algorithm is required. This algorithm can reappear the vehicle driving motions within workspace of the driving simulator. However classical washout algorithm contains several problems such as selection of order, cut-off frequency of filters, generation of wrong motion cues by characteristics of filters, etc. In order to overcome these problems, this paper proposes a new washout algorithm which gives more accurate sensations to drivers. The algorithm consists of an artificial inclination of the motion plate and human perception model with band pass filter and dead zone. As a result of this study, the motion of a real car could be reappeared satisfactorily in the driving simulator and the workspace of motion plate is restrained without scaling factor.

  • This paper addresses issues of perceptual constancy in speech perception through the use of a spatial metaphor for speech sound identity as opposed to a more conventional characterisation with multiple interacting acoustic cues. This spatial representation leads to a correlation between phonetic, acoustic and auditory analyses of speech sounds which can serve as the basis for a model of speech perception based on the general auditory characteristics of sounds. The correlations between the phonetic, perceptual and auditory spaces of the set of English voiceless fricatives /f $\theta$ s $\int$ h / are investigated. The results show that the perception of fricative segments may be explained in terms of 2-dimensional auditory space in which each segment occupies a region. The dimensions of the space were found to be the frequency of the main spectral peak and the 'peakiness' of spectra. These results support the view that perception of a segment is based on its occupancy of a multi-dimensional parameter space. In this way, final perceptual decisions on segments can be postponed until higher level constraints can also be met.

  • The present study examined if individual listeners' perceptual variations were associated with their cognitive characteristics indexed by the Autistic Spectrum Quotient (AQ). This study first investigated the perception of the lexical pitch accent contrast in the Kyungsang Korean currently undergoing a sound change, and then tested if listeners' perceptual variations were correlated with their AQ scores. Eighteen Kyungsang listeners in their 20s participated in the perception experiment where they identified two contrastive accent words for auditory stimuli systematically varying F0 scaling and timing properties; the participants then completed the AQ questionnaire. In the results, the acoustic parameters reporting reduced phonetic differences across accent contrasts for younger Kyungsang generation played a reliable role in perceiving the HH word from HL, suggesting the discrepancy between the perception and the production in the context of sound change. This study also observed that individuals' perceptual variations were negatively correlated with their AQ sub scores. The present findings suggested that the sound change might appear differently between production and perception with a different time course, and deviant percepts could be explained by individuals' cognitive measure.

  • Purpose: A descriptive study was conducted to examine the relationship of illness perception, self-efficacy, and self-care of patients who were diagnosed pulmonary tuberculosis. Methods: The study was conducted using a convenient sample from two hospitals in Incheon and Seoul. One hundred forty four patients completed a questionnaire which included questions on general characteristics, a Brief Illness Perception Scale, a Self-efficacy Scale and a Self-care Scale. Data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson Moment Correlations and stepwise multiple regression analysis. Results: There was a statistically significant positive correlation between illness perception and self-care (r=.335, p=.000) and between self-efficacy and self-care (r=.687, p=.000). Stepwise multiple regression analysis revealed that among the three variables the most powerful predictor was self-efficacy. Self-efficacy and illness perception were significant factors and accounted for 54.2% of the variance of self care in pulmonary tuberculosis patients. Conclusion: Self-efficacy and illness perception were influencing factors in self care among patients with pulmonary tuberculosis. Hence further interventional researches are needed that consider these two variables.

  • Purpose: The purpose of this study was to investigate the emergency-room nurse's perception and performance about the protection behavior of the consumer health information. Method: The participants were 191 emergency-room nurses in secondary, tertiary medical center nationally. The data were analyzed by SPSS 12.0 program. Result: First, the total average scores of the degree of the perception and performance by emergencyroom nurses on protection behavior of the consumer health information were $4.24{\pm}0.30$ and $3.51{\pm}0.26$. Second, the degree of the perception and performance on protection behavior of the consumer health information was heavily dependent on the following general characteristics of the participants: age, nurse position, career, and education experience on protection behavior of the consumer health information. Third, there was a positive correlation between the degree of perception and performance about the protection behavior of the consumer health information. Conclusions: The results showed the statistically significant partial correlation between the degree of perception and performance. Therefore, it is suggested to apply the concrete education program to enhance the perception in order to improve the performance.

  • The purpose of this study is to determine the Mediating Effects of Job Engagement between Perception in Compensation and Innovation Behavior in Chinese Enterprise Workers. The empirical study was conducted by a questionnaire survey on 700 workers in companies located in the southern area of China. The statistical analysis results revealed the following. First, the perception in compensation of Chinese workers has significant positive effects on the innovation behaviors. And intrinsic compensation has more relative significant effects than extrinsic compensation. Second, the perception in compensation has significant positive effects on the job engagement. In this case, extrinsic compensation has more relative significant effects than intrinsic compensation does. Third, job engagement of workers has significant positive effects on the innovation behaviors. Fourth, job engagement has mediating effects between perception in compensation and innovation behaviors. In conclusion, for the sustainable growth and competitive advantage of Chinese enterprises, it is important to perceive the needs of extrinsic and intrinsic perception in compensation of workers, and to design suitable compensation policies and programs to promote innovation behaviors and job engagement considering the distribution and procedural justice, and also to reflect the needs and job characteristics of workers.

  • Background and Objectives: The aim of this study is to evaluate the effect of music training on the characteristics of auditory perception of speech and music. The perception of speech and music stimuli was assessed across their respective stimulus continuum and the resultant plots were compared between musicians and non-musicians. Subjects and Methods: Thirty musicians with formal music training and twenty-seven non-musicians participated in the study (age: 20 to 30 years). They were assessed for identification of consonant-vowel syllables (/da/ to /ga/), vowels (/u/ to /a/), vocal music note (/ri/ to /ga/), and instrumental music note (/ri/ to /ga/) across their respective stimulus continuum. The continua contained 15 tokens with equal step size between any adjacent tokens. The resultant identification scores were plotted against each token and were analyzed for presence of categorical boundary. If the categorical boundary was found, the plots were analyzed by six parameters of categorical perception; for the point of 50% crossover, lower edge of categorical boundary, upper edge of categorical boundary, phoneme boundary width, slope, and intercepts. Results: Overall, the results showed that both speech and music are perceived differently in musicians and non-musicians. In musicians, both speech and music are categorically perceived, while in non-musicians, only speech is perceived categorically. Conclusions: The findings of the present study indicate that music is perceived categorically by musicians, even if the stimulus is devoid of vocal tract features. The findings support that the categorical perception is strongly influenced by training and results are discussed in light of notions of motor theory of speech perception.

  • The purpose of this study is to find out what kind of media perception can be experienced by the audience when artificial intelligence technology meets art, where new technologies are invented one after another. Among the artificial intelligence works, I selected works that stand out in relation to perception and investigated what kind of media perception the audience experiences when artificial intelligence technology meets art. By examining the characteristics of machine hallucinations, uncanny, and artificial empathy with the media perception of artificial intelligence art, these perceptions were ultimately identified as aura perception within family resemblance. In the future, artificial intelligence technology will develop further and artists will not stop experimenting with them. It is expected that the works created by artists will expand the audience's perceptual experience while providing new experiences to the audience.
