The current study investigates how student-teacher interaction can be developed through task-based teaching in undergraduate students' Saudi teaching and learning context. An experiment was conducted for five weeks on 85 male undergraduate students at a Saudi public university based in Jeddah, Saudi Arabia. The study investigated different types of student-teacher interaction through task-based teaching (speaking activities). The results revealed that the experimental group (43 students) evinced much more enthusiasm, willingness, engagement and readiness in their inclass participation than their peers in the control group (42 students). The student-teacher interaction also helped students to be more responsive to general and specific topics in speaking activities. The study recommends that decision-makers in education make student-teacher interaction part of the student's monthly assessment. It also recommends that more efforts be made to foster the awareness of students, teachers, and parents awareness of the academic and non-academic importance of interaction. One final recommendation of the research is that student-teacher interaction should be more emphasized and integrated into the school curriculum and adopted as a critical teaching strategy.

A social phobia is an anxiety disorder characterized by extreme fear and phobic avoidance of social and performance situations. Medications or cognitive-behavior methods have been mainly used in treating it. These methods have some shortcomings such as being inefficient and difficult to apply to treatment. Lately the virtual rcality technology has been applied to dcal with the anxiety disorders in order to compcnsate for these defects. A virtual environment provides a patient with stimuli which cvokes a phobia. and the patient's exposure to the virtual phobic situation make him be able to overcome it. In this study, we suggested the public speaking simulator based on a personal computer for the treatment of social phobia. The public speaking simulator was composed of a position sensor. head mount display and audio system. And a virtual environment for the treatment was suggested to be a seminar room where 8 avatars are sitting. The virtual environment includes a tracking system the trace a participant's head-movement using a HMD with position sensor and 3D sound is added to the virtual environment so that he might fcel it realistic. We also made avatars' motion and facial expression change in reaction to a participant's speech. The goal of developing public speaking simulator is to apply to treat fear of public speaking efficiently and economically. In a future study. we should get more information about immergence and treatment efficiency by clinical test and apply it to this simulator.

This study was done to understand nonpharmacologic pain management for pediateric patients and nurses' knowledge and attitudes toward it. The aim of this study was that which method did the patient's use according to the nurses' age, and how did they effectively use these methods in their field. The subjects of this study were 77 nurses working in the Pediatric unit in the Kyung Medical Center from September 2 to 15, 1999 using questionnaire form. The results of this study were as follows : 1. We divided the subjects into four groups : Younger than one year old, 1-6 years, 6-12 years, 12-18 years group. In the group younger one year old, most of the nurses participating in this study used speaking in soft quiet tones, supportive touch, toys, pacifiers. In the group of 1-6 years, they used speaking in soft quiet tones, toys, distracting attention, story talking, and visual stimulus. In the group of 6-12 years. they used pop-up books, providing information, cold therapy, speaking in soft quiet tones, supportive touch. In the group of 12-19 years, most of them used providing information, controling respiration and supportive touch. 2. The effective nursing intervention used in their field are speaking in soft quiet tones, pacifiers and nesting with blanket in the group of younger than one year old. Un the group of 1-6 years old, speaking in soft quiet tones, toys, and supportive touch were effective method in the control of nonp-harmacologic pain management. In the group of 6-12 years old, story talking, supportive touch, and speaking in soft quiet tones were effective method and in the group of 12-18 years old, providing information, cold therapy and supportive touch were effectively used to control nonpharmacologic pain management. 3. To compare the general characteristics and non-pharmacologic pain nursing intervention, in the group of younger than one year, touching stimuli is widely used. In the groups of 1-6, and 6-12 years old, visual and audio method were widely used. In the group of 12-18 years old, sensitive intervention were used as well as education, information and guided imagery. In conclusion, there was no significant difference in nurses' demographic characteristics, child's age and nonpharmacologic pain management. There was significant difference only in the nurses working area, that is nurses working in the surgical department used more audio-visual-tactile pain management methods than medical department.

The purpose of this paper is to research the phonetic parameters used on the voice imitation. First of all, the fundamental frequency is imitated effectively. Distinctive prosodic patterns are used repeatedly on the voice imitation. Speaking rate is used in special measure in case the target speaker has extraordinary speaking rate. Also formant frequency is imitated variously. In sum, distinctive characteristics perceived by listener are used on voice imitation.

Background and Objectives: The purpose of this study is to investigate the change of vocal tract length according to the level of the pitch by the singers. Materials and Methods: Fifteen tenors were asked to produce successive /a/ sound in G4(382Hz) for the head register, C3(131Hz) for the chest register and usual speaking sound. The control group consisted of 15 males of an similar age who are not professional singers. The length of vocal tract was calculated by applying the formula of Fn=(2n-1) c/4L(F : formant frequency, c : the speed of sound in the vocal tract(350m/sec), L : length of vocal tract, $n=1,2,3,4,{\ldots}{\infty}$). Results: In singer's group, there showed no significant statistical difference of length among head and chest register and usual speaking sound. However in the control group, there showed statistically significant difference of length. Comparison of the absolute difference in the length of vocal tract by changing level of pitch in phonation, between the control group and the singers group. Changing from G4 phonation to C3 phonation and C3 phonation to usual speaking sound showed statistically difference of vocal tract length was less in the singers group than the control group. Conclusion: The change of vocal tract length, in either speaking or singing, was less in singers than the control group. We could assume that the singers maintain their larynx position constantly throughout the pitch range when phonation.

Our present study was performed to investigate acoustically the Korean normal adults' voices, with enough large number of subjects to be reliable. 120 Korean normal adults (60 males and 60 females) of the age of 20 to 39 years produced sustained three vowels, /a/, /i/, and /u/ and read a part of 'Taking a Walk' paragraph, and by analyzing them acoustically with MDVP of CSL, we could get the fundamental frequency ($F_{0}$), jitter, shimmer and NHR of sustained vowels: speaking fundamental frequency ($SF_{0}$), highest speaking frequency (SFhi), lowest speaking frequency (SFlo) of continuous speech. As results, on the average, male voices showed 118.1$\sim$122.6 Hz in $F_{0}$, 0.467$\sim$0.659% in jitter, 1.538$\sim$2.674% in shimmer, 0.117$\sim$0.114 in NHR, 120.8 Hz in $SF_{0}$, 183.2 Hz in SFhi, 82.6 Hz in SFlo. And, female voices showed 211.6∼220.3 Hz in F0, 0.678∼0.935% in jitter, 1.478∼2.582% in shimmer, 0.098∼0.114 in NHR, 217.1 Hz in $SF_{0}$, 340.9 Hz in SFhi, 136.0 Hz in SFlo. Among the 7 parameters, every parameters except shimmer showed the significant difference between male and female voices. And, when we compared the three vowels, they showed significant differences one another in shimmer and NHR of both genders, but not in $F_{0}$ of males and jitter of females.
