The article considers the fundamentalization of education in improving the future specialists professional training with usage of multimedia technologies by various scientists. Various points of view and approaches to defining the concepts of fundamentalization of education and multimedia technologies are identified. The concept of fundamentalization of professional training of a future specialist is based on the goals and functions of fundamentalization and - on the ways and means of achieving it, etc. Most authors agree only in their views that the fundamentalization of education is aimed at improving the quality of education and the education of the individual. Others involve the formation of a culture and worldview, increasing the creative and intellectual potential, forming the professional competence of a specialist and the potential for further education, and so on. The term multimedia refers to interactive systems that provide processing of moving and still video images, animated graphics, high-quality audio and speech. It is found out that professional training of a specialist by means of multimedia technologies includes not only the activities of the teacher and student, which form the learning process, but also the independent activity of the subject, self-development, assimilation of experience by the subject through analysis, comprehension and transformation of the field of activity in which he is included. It is revealed through the implementation of which approaches to the fundamentalization of higher professional education, it becomes possible to fully present theoretical training courses and effectively pass practical training by students, which contributes to improving the quality of training of future specialists in higher education institutions. Theoretical analysis of scientific views indicates a fairly serious attention of scientists to the problem of professional readiness of specialists and the possibility of higher educational institutions in preparing for it. At the same time, professional readiness is considered from different positions: as an active state of a person, which manifests itself in activity; as a result of activity; as goals of activity; as a quality that characterizes the attitude to solving professional problems and social situations; as a prerequisite for purposeful activity; as a form of activity of the subject; as an integral formation of personality; as a component of socio-professional culture; as a complex professionally significant neoplasm of the individual.

This paper proposes a sinusoidal modeling of polyphonic audio signals. Sinusoidal modeling which has been applied well to speech and monophonic signals cannot be applied directly to polyphonic signals because a window size for sinusoidal analysis cannot be determined over the entire signal. In addition, for high quality synthesized signal transient parts like attacks should be preserved which determines timbre of musical instrument. In this paper, a multiresolution filter bank is designed which splits the input signal into six octave-spaced subbands without aliasing and sinusoidal modeling is applied to each subband signal. To alleviate smearing of transients in sinusoidal modeling a dynamic segmentation method is applied to subbands which determines the analysis-synthesis frame size adaptively to fit time-frequency characteristics of the subband signal. The improved dynamic segmentation is proposed which shows better performance about transients and reduced computation. For various polyphonic audio signals the result of simulation shows the suggested sinusoidal modeling can model polyphonic audio signals without loss of perceptual quality.

Today, people are exposed to the various noisy environments, such as in the buses, subway and supermarkets where there are a lot of people. The noise issue is getting more serious as people want to use portable sound equipment and mobile phones even under this noisy condition. People want to use the portable equipment to exchange the information freely and they set the volume as 15dB higher than the noise around them, which almost reach at 110 dB. That amount of sound can cause noise induced deafness to the users and another issue to the others as additional noise source. A Bone-conduction system can be a solution to reduce noise and enhance voice signal of mobile phone. In this paper, we propose the way of cancelling noise and enhancing speech signal of mobile phones, by installing bone-conduction feedback system with ordinary mobile phones. With this system, we can reduce the environment noise and enhance the voice quality of mobile phones. Using this method, we can enhance the signal by around 17 dB.

The purpose of this study was to classify the internal members of nursing hospitals and Western hospitals that received the certification system of medical institutions, and to examine the effect of certification on member satisfaction, job stress, hospital operation effect, and improvement of medical services. In nursing hospitals, the certification system was higher in member satisfaction, hospital operation effect, and medical service effect than in Western hospitals, and members of Western hospitals were higher in job stress. In both nursing hospitals and Western hospitals, the satisfaction of members, hospital operation effect, and medical service effect according to certification showed positive (+) results. It is believed that the effect of the certification system has been empirically high in nursing hospitals as mandatory certification from 2013. Therefore, this study aims to contribute to the efficiency of hospital management and improvement of patient satisfaction through continuous quality management of medical care by analyzing the effect of certification system on medical service improvement.

In this paper, the performance enhancement algorithm of channel allocation for voice and data transmission in cellular networks is proposed. The voice activity detection has been applied to dynamic channel allocation procedure to detect and separate the silence and speech among conversation periods. Hence a data user can use the silent period of an active voice channel to transmit its information. To control the selecting of channel allocation policies, the information of number of data in transmission waiting queue has been determined in order to accept the performance measurement. In the simulation results, the improvement of the performance shows via the quality of services, which are an average delay in queue, a blocking probability, and an impact of the proposed scheme is presented in the system.

Patients with cleft lip and palate (CLP) must undergo corrective surgeries during infancy and early childhood. Many patients with CLP undergo orthognathic surgery during their childhood for correction of skeletal asymmetries or pharyngoplasty with a pharyngeal flap to improve the quality of speech and velopharyngeal function. During orthognathic surgeries, nasotracheal intubation is performed under general anesthesia. In our case report, the patient had undergone palatoplasty and pharygoplasty previously. During the orthognathic surgery, a flexible fiberoptic bronchoscope-guided nasotracheal tube was inserted through the pharyngeal flap ostium; however, active bleeding occurred in the nasopharynx. Bleeding occurred because the flap was torn. After achieving hemostasis, the surgery was completed successfully. Thus, if a patient may show the potential for velopharyngeal port obstruction, nasotracheal intubation should be performed with utmost care.

Spasmodic dysphonia is a chronic, focal, movement-induced, action-specific dystonia of the laryngeal musculature during speech. It can have a profound effect on quality of life, severely limiting people's communication, especially via telephone and in noisy backgrounds. Spasmodic dysphonia (SD) is usually of the adductor type characterized by glottic contractions causing tightness and voice breaks with forced-strangled voice, but it may also be abductor type or, much less commonly, mixed. Treatment options for adductor spasmodic dysphonia (ADSD) include voice therapy, surgical procedures, and botulinum toxin injections (Botox). The use of Botox injected into the laryngeal muscles remains the "gold standard" treatment for reducing the vocal symptoms of ADSD and Botox induces a temporary paresis of the laryngeal muscles and provides short-term relief of symptoms. Repeated injections of the laryngeal muscles, generally every 3-4 months, are required for continuous relief of symptoms. Improvement in vocal function has been reported after use of Botox injections, though a completely normal voice is rarely achieved. In this hospital, 1,030 patients have been enrolled for Botox injection therapy so far (May, 2012). In this review article, I'd like to present my personal experience of management of spasmodic dysphonia mainly by Botox injection.

Code Excited Linear Prediction(CELP) speech coders exhibit good performance at data rates below 4.8 kbps. This major drawback of CELP type coders is required much computation. In this paper, we propose a new pitch search method that preserves the quality of the CELP vocoder with reducing complexity. In the pitch searching, we detect the segments of high correlation by a simple preprocessing, and then carry out the pitch searching only for the segments obtained by the preprocessing. By using the proposed method, we can get approximately $77\%$ complexity reduction in the pitch search.

The aim of this study was to test the feasibility of a wireless transceiver that can be inserted into the ear canal. The wireless technology could minimize the cosmetic problems of patients, and it can be applied to binaural hearing aids for improving speech perception. In order to implement the ear canal insertable transceiver, simple finite-difference time-domain (FDTD) simulations were carried out to determine the feasibility, and the hardware of the transceiver was implemented within the ear shell. The size of the implemented transceiver was only $7{\times}7mm$, and it could successfully transmit signals to external devices. In order to measure the radiation pattern, a simple RF phantom was used, and the maximum attenuation from the phantom was observed to be 23 dB when the reference antenna was placed at a distance of 2 m from the transmitter.
