"A method for locating abnormal sound in transmission line channels based on time delay estimation and equipment coordinates." Journal of Physics: Conference Series 2384, no. 1 (December 1, 2022): 012005. http://dx.doi.org/10.1088/1742-6596/2384/1/012005.
Full textAbstract:
Abstract To get rid of the current transmission line visual monitoring device which only relies on a single photo-monitoring method, this paper proposes a method based on time-delay estimation and equipment coordinates to locate abnormal sound in the transmission line channel. Firstly, the audio-visual equipment is selected to collect the abnormal sound information of any transmission line as the reference warning record, and the relative time difference between other warning records and the reference warning record is determined. Then, the corresponding audio-visual equipment of the reference alarm record is used as a reference point to set up a Cartesian coordinate system, obtain the GPS information of other audio-visual equipment, unify the GPS information, and get the coordinates of other audio-visual equipment; finally, based on the reference point coordinates, other audio-visual equipment coordinates, and the relative time difference, the transmission channel abnormal sound source coordinates are obtained. Through the experiment of firecracker sound, we can get the firecracker sound within 2km in the open environment, which proves that the location method can effectively enhance the monitoring effect of the transmission channel.

Full textAbstract:
Audio-visual records and archives constitute a fundamental heritage that satisfies multiple needs, including education, training, research and entertainment. As such, there is a need to appropriately preserve and conserve them so they can be accessed for as long as they are needed. In spite of their significant role in safeguarding cultural heritage, audio-visual records and archives, are often neglected and accorded less attention than paper-based records, especially in developing countries. Hence, there is a risk of losing information held in audio-visual form. That is why this study looked at how the National Archives of Zambia (NAZ) and the Zambia National Broadcasting Corporation (ZNBC) preserve audio-visual materials to ensure long-term accessibility of the information. The study investigated the types of audio-visual collections held, the storage equipment used, measures put in place to ensure long-term accessibility of audio-visual materials, the disaster preparedness plans in place to safeguard audio-visual archives and the major challenges encountered in the preservation of audio-visual materials. The findings of the study revealed that films (microfilm and microfiche), photographs and manuscripts, and video (video tapes) and sound recordings (compact cassette) constitute the biggest audio-visual collection preserved. The equipment used to store audio-visual materials included open shelves, specialised cabinets, electronic database for digitised materials, aisle mobiles and cupboards. The measures taken to ensure the long-term accessibility of audio-visual collection included digitisation and migration of endangered records and archives; fumigation of storage areas; conservation of damaged materials and regulation of temperatures and humidity in the storage areas. The disaster preparedness plans in place mostly covered structure insurance; protection against fire and water by way of installing fire extinguishers; smoke sensors; fire detectors and construction of purpose-built structures. The major challenges faced were financial constraints; technological obsolescence; lack of playback equipment; limited training; lack of strong back-up systems and inadequate storage facilities.

This research aims to assess the availability of audiovisual equipment and materials in schools and their practical usage in classroom teaching. The research design used is quantitative descriptive, and the instrument utilized for this research is a questionnaire. The data analysis technique employed is the Miles and Huberman Interactive analysis model. This study was conducted in 5 middle schools, with seven teachers as research subjects. The findings of this research indicate that the status of audiovisual equipment needs to be improved. Computers, televisions, tape recorders, and public address systems are only owned by 64.62% of the schools. Variables such as school management type, school age, school resources, and school strength do not significantly influence the possession of adequate or inadequate equipment in the schools. A total of 87.4% of the schools have effectively used audiovisual equipment. The school administration has yet to make any efforts to properly procure and utilize audiovisual equipment and materials, primarily due to the financial challenges associated with equipment maintenance.

The purpose of this study is to explore the audio-visual preferences of exercisers in urban forest parks in China and to make practical suggestions for park landscape design. Taking Beigushan Forest Park in Lianyungang City, Jiangsu Province as a case, based on field research and questionnaire survey, this study analyzed the audio-visual preference characteristics of exercisers in the park, revealed the correlation between audio-visual preference and exercisers’ behaviors and individual characteristics, and explored the influence of audio-visual preferences on exercise feelings by establishing a structural equation model. It was found that (1) the forest and its avenue landscape and birdsong are most preferred by exercisers; (2) the audio-visual preferences of people with different exercise forms differ, for example, people who slowly walk, run, and briskly walk have stronger preferences for natural soundscape and visual landscape, while people who use fitness equipment have stronger inclusiveness for human activity sound and prefer public facility-based landscapes. In addition, some individual characteristics such as exercise intensity and exercise frequency significantly affect exercisers’ audio-visual preferences; (3) visual landscape preferences have a greater direct impact on exercise feelings, with natural waterscape having the greatest direct impact, but overall soundscape preferences do not have a high degree of direct impact on exercise feelings, with natural sound still having a strong positive impact. These findings provide a more quantitative basis for the landscape design of urban forest parks from the perspective of exercise behavior.

Recognition of Kazakh language as the state language of the Republic of Kazakhstan by the Constitution of the Republic of Kazakhstan, adoption of ‘State programme of functioning and development of languages for 2011–2020’, the Law of the Republic of Kazakhstan ‘On languages of the Republic of Kazakhstan’, ‘The State programme on education and science development for 2016–2020’ allowed our native language to develop and prosper. Nowadays, special attention is paid to the problem of teaching the Kazakh language. In today's organised pedagogical environment, it is not fully examined the need for the development of communication skills of elementary school students and scientifically-based and practical communication to solve this problem via audio and graphic tools. Therefore, this article focuses on the need to teach elementary school students to work with audio and graphic materials and technology issues on the use of practical materials. Provided that the theoretical foundations for the development of communication skills of elementary school students through audio-visual aids hold true, the structural-substantial model will allow the development of each student’s individual abilities and creativity. Taking into account the foregoing, we have set up a positive outline of the effectiveness of the work with audio equipment through the organisation of practical work, practice-assemblage, research, diagnostics, practical work in elementary school teachers through specially organised thematic seminars

Background: Appropriate and cautious doffing is vital to prevent self-contamination and infection from the highly contagious SARS-CoV-2 virus. In current study satisfaction levels of front-line health care workers regarding doffing assisted by a novel real-time remote audio-visual aided approach was assessed.Methods: A questionnaire-based survey was carried out among 158 health care workers. The questionnaire was developed and validated to assess the participants’ satisfaction level regarding the instructions being given remotely for doffing through the real-time remote audio-visual aided technique pertaining to the various facilities available for doffing, remote communication for doffing steps, audio-visual technical issues, rectification of the breach in safety and the level of anxiety.Results: The survey received a 79% response rate. 74.6% of the respondents were highly satisfied. 61.9% agreed on the adequacy of doffing space, 70.9% strongly agreed/agreed regarding the availability of adequate equipment, 78.5% strongly agreed/agreed with the instructions. The overall median (IQR) satisfaction score was 9 (8-10).Conclusions: Real-time remote audio-visual aided doffing approach is a simple, technology-aided strategy that is shown to enhance the satisfaction and motivation of the health care workers. This can potentially help in reducing the number of personnel required in directly monitoring doffing leading to freeing up more people to work with the patients while reducing unnecessary exposure. This translates to effective utilisation of resources. The high satisfaction associated with the use of this system boosts the feasibility of its implementation in every tertiary care setup.

The data in this research comes from primary and secondary data. Data collection methods use observation, interviews and documentation. Interviews were conducted with the community at the PkM location. The research results obtained in the implementation of coaching on the use of audio-visual media consist of several stages. First, the teacher makes preparations by preparing equipment in the form of a projector, sound system, laptop and children's story CDs. Second, the teacher carries out apperception, such as asking questions about the story they are going to learn. Then, the teacher conditions the children to sit neatly and comfortably, after that the teacher shows a video with a duration of 15 minutes. After that, the teacher and children conduct questions and answers regarding the video that has been presented and give the children worksheets to measure the extent to which the children understand the material presented using audio-visual media. With this audio visual learning media, children are able to: increase interest in learning, motivate them in the learning process, and children get a real picture of the concepts being studied and this becomes an advantage in itself. The inhibiting factors in efforts to maximize the use of visual media are human resources, infrastructure and also less than optimal internet signals

Full textAbstract:
It is noteworthy nowadays that monitoring and understanding a human’s emotional state plays a key role in the current and forthcoming computational technologies. On the other hand, this monitoring and analysis should be as unobtrusive as possible, since in our era the digital world has been smoothly adopted in everyday life activities. In this framework and within the domain of assessing humans’ affective state during their educational training, the most popular way to go is to use sensory equipment that would allow their observing without involving any kind of direct contact. Thus, in this work, we focus on human emotion recognition from audio stimuli (i.e., human speech) using a novel approach based on a computer vision inspired methodology, namely the bag-of-visual words method, applied on several audio segment spectrograms. The latter are considered to be the visual representation of the considered audio segment and may be analyzed by exploiting well-known traditional computer vision techniques, such as construction of a visual vocabulary, extraction of speeded-up robust features (SURF) features, quantization into a set of visual words, and image histogram construction. As a last step, support vector machines (SVM) classifiers are trained based on the aforementioned information. Finally, to further generalize the herein proposed approach, we utilize publicly available datasets from several human languages to perform cross-language experiments, both in terms of actor-created and real-life ones.

Interactive video conferencing has the advantages of having audio and visual contact with students during a set class period while having the disadvantages of scheduling multiple locations and keeping the equipment functioning at peak performance. Likewise, using a web platform such as WebCT provides a framework with excellent options to develop a course that is both audio and visually rich. This solution also presents its own difficulties as required textbooks change and the platform version may be upgraded. In this presentation, the advantages and disadvantages of both formats will be reviewed. In addition, helpful hints for blending these two teaching methods together to create a custom course will be discussed.

Objective The aim of this study is to determine the effects of a powered exoskeleton on measures of physical and cognitive performance. Background US warfighters carry heavy equipment into battle, and exoskeletons may reduce that burden. While exoskeletons are currently evaluated for their effects on physical performance, their cognitive effects are not currently considered. Method Twelve military members participated in a simulated patrol task under three conditions: wearing a powered exoskeleton (PWR), an unpowered exoskeleton (UNP), and without wearing an exoskeleton (OFF). While following a confederate over obstacles at a constant pace, participants performed additional audio and visual tasks. Dependent measures included visual misses, visual reaction time, audio misses, audio reaction time, incremental lag time, and NASA-TLX scores. Results The variability in the follow-task lag time was lowest with OFF and highest with UNP, highlighting reduced ability to maintain pace with the exoskeleton. Visual reaction time was significantly slower with PWR compared to OFF for 5 of 12 subjects. The NASA-TLX overall workload scores were lower for OFF compared to PWR and UNP. Conclusion Efforts to understand individual variability are warranted such that exoskeleton designs can be used for a wider set of the population. While not all subjects had measurable differences in the selected performance tasks, the perception of increased workload was present across subjects. It remains to be determined what difference in reaction time would be operationally relevant for task-specific settings. Application Findings draw attention to the need to consider “cognitive fit” and subject differences in the design and implementation of exoskeletons.

Full textAbstract:
This descriptive quantitative study aims to examine how university lecturers think about employing audiovisual materials in terms of the benefits and challenges that they experienced in their EFL classes. The data was gathered from 155 English lecturers at universities in the Mekong Delta via a questionnaire that included 35 closed-ended questions and two open-ended questions. The study's findings demonstrated that participants' attitudes about using audiovisual aids in their EFL classrooms are overwhelmingly favorable. These educators concurred that using audiovisual aids during class not only makes their teaching easier but also benefits students' language skills development and English vocabulary growth thanks to the engaging, interactive qualities of instructional materials. The findings also show that audiovisual assistance will be challenging when technological equipment is insufficient. To improve the effectiveness of their teaching, lecturers must also keep up with technology advancements and create lesson plans that incorporate audiovisual materials.

The study aims at investigating the relationship between teachers’ utilization of instructional materials and students’ attitudes towards learning science subjects in Rwandan secondary schools. The sample size comprised sixty-three science secondary school teachers in Muhanga district that were selected purposively to participate in the study. A descriptive research design was used and data were collected using an online designed survey using google form. Teachers Scale Questionnaire for the use of Instructional materials and students’ exhibited attitudes questionnaire each contained seven affirmative statements were used as the research tools. Participants’ responses were based on the five point Likert scale to disclose their perceptions in relation to the topic being investigated. The findings from Pearson’s Product Moment Correlations (r) indicated that constructs used were strongly correlated, moderately correlated, and few were weakly correlated. Use of illustrations, use of photographs and visual aids to demonstrate concepts enhance students’ remembering and retention of instructions therefore the variables exhibit strong correlations (r = .923; .803). Use of laboratory equipment and reagents during experimentation, use of models and drawings to illustrate concepts exhibited a moderate correlation with students’ classroom participation (r = .449; r = .785). Creativity and innovation and integration of audio-visual aids into lessons were strongly correlated (r = .947). Strong correlations were found between use of tech-tools during classroom practices (r = .871), use of a variety of instructional materials (r = .901) and creativity and innovation. Interestingly, use of printed materials, visual aids, and audio-visual aids lead to improved students’ classroom interaction, and was strongly correlated with teachers’ integration of audio-visual teaching and learning aids into lessons (r = .889). The findings of this study constitute the basis to validate the relationship between teachers’ use of instructional materials and students’ attitudes in the learning process. We therefore recommend teachers to maximize the use of variety of instructional materials during classroom practices.

In recent times, the use of subtitles and audio descriptions in movies for individuals with either hearing or visual impairment and the need to develop systems to provide these have been realized. However, even the need and possibility for deaf-blind individuals to enjoy movies have not been discussed yet. This study created an environment for deaf-blind individuals to “watch” a film, and conducted a screening of feature-length films with subtitles and audio descriptions. Interviews of 26 deaf-blind individuals indicated that 56% had watched films in a theater after becoming deaf-blind and before the screening session. When watching the films, 26.9% of participants used individual monitoring devices, headphones, or other conventional video or audio equipment. Furthermore, 50% were able to use either subtitles or audio descriptions. Regardless of their impairment conditions, participants responded positively towards watching the film in the screening session. Among the deaf-blind, 42.1% of the partially sighted and deaf, blind and hard of hearing, and partially sighted and hard of hearing individuals appreciated a special aspect of the theater, i.e., “sharing an opportunity and communication with others.”

Orthopaedic simulators are popular in innovative surgical training programs, where trainees gain procedural experience in a safe and controlled environment. Recent studies suggest that an ideal simulator should combine haptic, visual, and audio technology to create an immersive training environment. This article explores the potentialities of mixed-reality using the HoloLens to develop a hybrid training system for orthopaedic open surgery. Hip arthroplasty, one of the most common orthopaedic procedures, was chosen as a benchmark to evaluate the proposed system. Patient-specific anatomical 3D models were extracted from a patient computed tomography to implement the virtual content and to fabricate the physical components of the simulator. Rapid prototyping was used to create synthetic bones. The Vuforia SDK was utilized to register virtual and physical contents. The Unity3D game engine was employed to develop the software allowing interactions with the virtual content using head movements, gestures, and voice commands. Quantitative tests were performed to estimate the accuracy of the system by evaluating the perceived position of augmented reality targets. Mean and maximum errors matched the requirements of the target application. Qualitative tests were carried out to evaluate workload and usability of the HoloLens for our orthopaedic simulator, considering visual and audio perception and interaction and ergonomics issues. The perceived overall workload was low, and the self-assessed performance was considered satisfactory. Visual and audio perception and gesture and voice interactions obtained a positive feedback. Postural discomfort and visual fatigue obtained a nonnegative evaluation for a simulation session of 40 minutes. These results encourage using mixed-reality to implement a hybrid simulator for orthopaedic open surgery. An optimal design of the simulation tasks and equipment setup is required to minimize the user discomfort. Future works will include Face Validity, Content Validity, and Construct Validity to complete the assessment of the hip arthroplasty simulator.

ABSTRACT Integration in operation theater (OT) usually refers to systems integration, which means functionally connecting the OT environment. It includes integration of patient information system, audio, video, surgical lights and room lights, building automation (HVAC), medical equipment, telemedicine, videoconferencing, etc. When integrated, all technology can be manipulated from a central command console by single operator. Integration in OT holds the key for effective application of minimally invasive surgery, robotic surgery and functioning of hybrid OT. Apart from the conventional planning team for an OT, bringing on board an IT professional is a must for planning IT requirements. Integration in OT requires 15% more space than the conventional OT in order to accommodate the IT gadgets, i.e. walk-in technology room that would house teleconferencing and A/V equipment, blade-server computers, fiberoptic network electronics, teleconferencing and video conferencing equipment, audio-visual racks, etc. the level of integration can vary within an OT depending upon the user requirement. Space requirement for a general I-OT is about 60 m2, a cardiovascular I-OT or one that includes robotics may come up to 80 m2 or more, and I-OT with in-room imaging equipment requires at least 100 m2. Integration in OT not only increases the efficiency and patient safety in delivery of healthcare but can significantly increase efficiency and effectiveness both in teaching and research.

Pediatric patients are generally uncooperative during radiology examinations. Radiographic images can become blurry due to movement. This will cause to repeat examinations, thereby significantly increasing radiation exposure, and it can pose significant risks to children, patient families, and radiation workers. The research aims to create and test the effectiveness of a fixation device equipped with Audio-Visual elements for pediatric chest radiography examinations in Anteroposterior and Lateral projections. The experimental method involves developing the fixation device in the Radiodiagnostic Department Laboratory of Poltekkes Kemenkes Jakarta II. The effectiveness of the fixation device is assessed through surveys and interviews involving 66 respondents at hospitals in Jakarta from January to July 2023 during pediatric chest examinations. The average results indicate that the device can be used in hospitals (3.27±0.63), it’s safe to use (3.00±0.74), and highly effective (3.17±0.67). The overall average value of 3.16±0.68, suggests that the fixation device is suitable for use in pediatric chest examinations. The obtained images from the Anteroposterior and Lateral projections optimally describe of lung organs, the heart, and blood vessels within the thoracic cavity. Suggestions for further development of the safe device include the addition of leg supports, pediatric chair can be moved forward/backward and patient restraints to prevent falling or movement

The development of education libraries cannot be understood outside the context of education history. Changes in educational practices and technology spurred three phases of development in the history of education libraries. Early examples, often called curriculum laboratories, developed as spaces to create educational materials where limited numbers existed. As standardized curriculum grew, common laboratories gave way to curriculum materials centers, which housed materials so that future teachers could preview them. The rise of audio-visual equipment transformed education libraries once again into centers housing a variety of instructional materials. This paper traces the development of education libraries through these three phases.

Sudden cardiac death is a sudden and highly fatal condition. Implementing high-quality emergency cardiopulmonary resuscitation (CPR) early on is an effective rescue method for this disease. However, the rescue steps of CPR are complicated and difficult to remember, and the quantitative indicators are difficult to control, which leads to a poor quality of CPR emergency actions outside the hospital setting. Therefore, we have developed CPR emergency equipment with a multisensory feedback function, aiming to guide rescuers in performing CPR through visual, auditory, and tactile interaction. This equipment consists of three components: first aid clothing, an audio-visual integrated terminal, and a vital sign detector. These three components are based on a micro-power WiFi-Mesh network, enabling the long-term wireless transmission of the multisensor data. To evaluate the impact of the multisensory feedback CPR emergency equipment on nonprofessionals, we conducted a controlled experiment involving 32 nonmedical subjects. Each subject was assigned to either the experimental group, which used the equipment, or the control group, which did not. The main evaluation criteria were the chest compression (CC) depth, the CC rate, the precise depth of the CC ratio (5–6 cm), and the precise rate of the CC ratio -(100–120 times/min). The results indicated that the average CC depth in the experimental group was 51.5 ± 1.3 mm, which was significantly better than that of the control group (50.2 ± 2.2 mm, p = 0.012). Moreover, the average CC rate in the experimental group (110.1 ± 6.2 times/min) was significantly higher than that of the control group (100.4 ± 6.6 times/min) (p < 0.001). Compared to the control group (66.37%), the experimental group showed a higher proportion of precise CC depth (82.11%), which is closer to the standard CPR rate of 100%. In addition, the CC ratio of the precise rate was 93.75% in the experimental group, which was significantly better than that of 56.52% in the control group (p = 0.024). Following the experiment, the revised System Availability Scale (SUS) was utilized to evaluate the equipment’s usability. The average total SUS score was 78.594, indicating that the equipment’s acceptability range was evaluated as ‘acceptable’, and the overall adjective rating was ‘good’. In conclusion, the multisensory feedback CPR emergency equipment significantly enhances the CC performance (CC depth, CC rate, the precise depth of CC ratio, the precise rate of CC ratio) of nonprofessionals during CPR, and the majority of participants perceive the equipment as being easy to use.

Cryogenic electron microscopy (cryoEM) has emerged as a revolutionary method for solving high-resolution structures and studying the dynamics of macromolecular complexes and viruses in near-native states. However, the availability of the equipment, and the time and cost needed for training, severely limit the opportunities for training. To solve these problems, a virtual reality-based training system, CryoVR, has been developed to prepare trainees before operating real-world cryoEM equipment. This paper describes the design and assessment of CryoVR (available at https://www.purdue.edu/cryoVR), which helps users learn cryoEM experimental procedures in a virtual environment, allowing immersive training with step-by-step tutorials with vivid visual, audio and text guidance. Implemented as a training step before a novice user interacts with the expensive real-world cryoEM equipment, CryoVR can help users to become familiar with hands-on operational procedures through multiple training modules and earning certificates after passing the built-in Exam mode. Qualitative evaluation and feedback of CryoVR from users with various levels of cryoEM experience indicate the substantial value of CryoVR as a tool for a comprehensive cryoEM procedural training.

In this article, we argue that physical rooms cannot be replaced by virtual space without literally losing the student’s body and that experimenting with rooms and active learning is imperative for improving and advancing students’ learning. Our case study offers insight into a ‘soft room experiment’ without hard furniture or audio-visual equipment at one Australian university and makes recommendations that will be useful in many other educational environments. Our qualitative research project is based on feedback from students and staff as well as on class observation. Findings show that learning spaces need to be designed with appropriate pedagogies in mind, be multifunctional and ideally also multi-sensory.

The article is devoted to clarifying the essence and procedural order of computer data examination in criminal proceedings. This type of examination, as defined by the Law of Ukraine No. 2137-IX dated 15.03.2022, is a novelty of criminal procedure legislation and requires theoretical elaboration. It is noted that the legislative consolidation of the types of examination should be determined by the need to establish specific procedural requirements for their conduct. It is specified that the direct object of such an examination is the audio-visual representation of computer data, which is defined as information contained in the storage device of an electronic computer in a format suitable for processing, transmission and interpretation by computer computing devices.
Within the framework of the article, the examination of computer data is distinguished from the examination of computer equipment (by the object criterion) and from the removal of information from electronic information systems (by the (non)secrecy criterion). The author emphasises that the procedural order of the analysed procedural action is regulated by Articles 104, 105, 223, 237 of the CPC of Ukraine, as well as the requirements for collection and verification of evidence (Chapter 4 of the CPC of Ukraine), the principles of criminal proceedings (Chapter 2 of the CPC of Ukraine) and other general provisions of criminal procedural legislation. The subjects of the computer data examination are the investigator, prosecutor, coroner, detective and operative officer (upon written order).
It is recommended to conduct the investigated procedural action involving a specialist. The computer data examination is defined as a public investigative (detective) action carried out by the prosecution with the use of electronic computing equipment by means of direct perception of audio-visual expression of computer data in order to obtain information about facts relevant to criminal proceedings.

To learn a lesson well, we need to hear, see, ask questions about it, and discuss it with others. Not only that, teachers need to "do it", that is to describe something in their own way, to show their example, to try to practice their skills and to do tasks that demand the knowledge they have gained.Problems that want to be studied in this research are: Is using Audio-Visual model in students of class IX SMP Negeri 2 Painan year 2015 – 2016. Steps in using the Audio-Visual implementation method? This research was conducted in class VII of SMP Negeri 1 Painan. This place was chosen because based on the results of class observations and interviews with English teachers in the classroom it can be concluded that the skills of students listening in English is still low. This is because teachers do not use adequate techniques, limited books that are in school and media equipment is still lacking. Research time. This research was conducted from early October as a description of the implementation of this study can be seen in the following table: This stage is intended to thoroughly review the actions that have been done, based on data that has accumulated in the previous step. And look for difficulties experienced by students and teachers in the process of action that has been done. Students are invited to discuss each cycle to ask about their difficulties. The teacher reflects on past events as the process of action takes place. All the data obtained are analyzed and evaluated to refine the action in the next cycle or whether or not the treatment given to the students is continued. By knowing that the triggers of low learning activity and learning achievement are in factors such as the method used by the teacher, so the use or replacement of conventional methods into constructivist methods is indispensable, consequently the researchers tried the Audio-Visual learning model in an attempt to solve problems at school. Based on the low learning activities and student achievement that are presented on the background of the problem, the use of Audio-Visual learning model attempted to be able to complete the purpose of this research is to know the improvement of student achievement. How much improvement has been made clear at the end of the analysis. From the results of the research presented in Chapter IV and all the data that have been submitted, the research objectives submitted can already be achieved. To answer the purpose of research is the achievement of student prestai achievement can be seen evidence that has been submitted. From the baseline data almost all students got the score below, then in cycle I decreased to 8 students and cycle II scores all students above the standard specified in the school. From the initial average of 4.5 increased to 6.3 in cycle I and on the second cycle rose to 7.9. From the initial data no students are complete while in cycle I become more that 4 students and on cycle II all students reach mastery.From all supporting data proving the achievement of learning objectives can be submitted that Audio-Visual model can give the expected answers according to the purpose of this study. All this can be achieved is due to the readiness and hard work of researchers from the time of making the proposal, review the things that have not been good with friends of teachers, preparation of grids and research instruments, the use of means of data triangulation to the implementation of the maximum research.

Universities have a role and function to educate the community in addition to conducting lectures. One form of activities from this role is to provide information to the community in the form of providing guidance, sharing knowledge or training. With the advancement of internet technology today, this can be done through online platform. However, this must be supported by qualified equipment in order to gain interesting and acceptable outcomes for the community as well as students. In this service, a studio that can be used to support teaching activities and community counselling for academic community in Politeknik Negeri Bandung is created. The making of this broadcast studio is divided into three stages. The first is the making of a three-dimensional model of the room using 3D modelling software. The second stage is the civil work to build a broadcast studio. The last stage is the completion of the broadcast studio with supporting equipment for video content creation. The results obtained are quite satisfactory. From the majority of answers obtained from the survey, students find this studio useful, quite comfortable to use and worthy of creating video content. For the audio section, the correspondents believe that this aspect still needs to be improved, while the room layout and visual equipment are considered good and attractive.

The use of audio visual media based on YouTube channels can shape the character of children at Al-Ikhsan TPA, especially children who have religious, honest, curious, hard working, social care and responsibility characters. Learning using the YouTube channel has several obstacles, including an unstable network and bad weather, resulting in changes to the learning schedule. Therefore, researchers provide recommendations in the form of adding a learning schedule by utilizing the YouTube channel 2-3 times a week, this is done so that children's character formation becomes more effective and optimal.

Full textAbstract:
Contemporary research equipment is not only extremely complex and very expensive, it is typically fully computerized and most tasks are executed without student participation. This creates a number of substantial educational drawbacks and limitations. The paper presents a virtual multifunctional X-ray laboratory (v-Lab) that helps overcome the above mentioned problems, addresses the demands of distance and blended education and meets learning habits of today's students. The v-Lab enables students to practice concepts, tasks, and equipment operations in a manner that can't be achieved on actual equipment. It employs virtual X-ray equipment that realistically imitates the functionality and design of actual equipment and also includes educational analytical software. Virtual data can be exported to popular software as well. Highly interactive online experiments using virtual equipment have been created for undergraduate students to learn fundamental principles underlying the analytical x-ray methods and become familiar with the design and operation of the X-ray equipment. A variety of visual, audio and traditional learning and assessment resources were integrated with virtual experiments to provide students with "just-in-time" learning opportunities. The virtual equipment has also been used for preparing undergraduate and graduate students to perform various research studies including but not limited to: X-Ray diffraction study of phase transitions in ferroelectric ceramics and nanoscale thin films, qualitative phase analysis of various compounds, nanostructured materials and human kidney stones, etc. Examples of virtual experiments used for teaching crystallography and other science and engineering courses at several US and Russian universities are presented and discussed. An easy-to-use authoring tool enables instructors to customize existing virtual experiments, and create new ones, as well as to add their own samples into the sample collection.

Full textAbstract:
From prehistorical archaeological sites to middle-American banks, classic Nashville recording studios, and present-day concert halls, spatial acoustics influence human experience, behavior, and interactions. We previously proposed a definition of aural heritage: “spatial acoustics as physically experienced by humans in cultural contexts,” and have tested equipment and methods to document aural heritage in diverse sites. In fieldwork and in the studio/lab, we have evaluated and extended standard room acoustics techniques to address ecological validity (realism) in aural heritage preservation including specific human-centered methods. For the translation of aural heritage data into auralizations, we have focused on multichannel audio with and without congruent visual immersion, anticipating multimodal virtual reality presentations of cultural heritage reconstructions. Here, we overview our multi-year project to develop, test, and share aural heritage preservation, translation, and access technologies via three detailed case study applications and associated outreach projects. We (1) summarize the translatable aural heritage data collection protocol for long-term preservation; (2) discuss preferred methods for processing aural heritage data into scalable auralizations for different audio platforms; and (3) preview extensibility pathways for other researchers to implement these methodologies that enable researchers and public audiences to explore and experience this aspect of intangible culture.

Full textAbstract:
With the advent of innovative technology, many traditional schools have resorted to modern techniques to facilitate student learning. Early steps recognize the role of technology in education. Which indicates the importance of audio-visual equipment like tele media, recording media, computer etc. Thus, educational technology emphasizes the art of employing so-called hardware, innovative media, and machine industry methods for educational purposes. It has now become clear that the systematic way in which technology is used to achieve a purpose is as important as the use of technology. Today the software aspect of educational technology has reached an important point i.e. it is useful in molding behavioural practices or in other words useful for solving problems of promoting learning and motivation. The most widely known meaning of educational technology today is more special than the acquisition of its hardware or software.

"Telehealth language assessments using consumer grade equipment in rural and urban settings: Feasible, reliable and well tolerated." Journal of Telemedicine and Telecare 23, no. 1 (July 9, 2016): 106–15. http://dx.doi.org/10.1177/1357633x15623921.
Full textAbstract:
Introduction Telehealth can be an effective way to provide speech pathology intervention to children with speech and language impairments. However, the provision of reliable and feasible standardised language assessments via telehealth to establish children’s needs for intervention and to monitor progress has not yet been well established. Further, there is limited information about children’s reactions to telehealth. This study aimed to examine the reliability and feasibility of conducting standardised language assessment with school-aged children with known or suspected language impairment via a telehealth application using consumer grade computer equipment within a public school setting. Method Twenty-three children (aged 8–12 years) participated. Each child was assessed using a standardised language assessment comprising six subtests. Two subtests were administered by a speech pathologist face-to-face (local clinician) and four subtests were administered via telehealth. All subtests were completed within a single visit to the clinic service, with a break between the face to face and telehealth sessions. The face-to-face clinician completed behaviour observation checklists in the telehealth and face to face conditions and provided feedback on the audio and video quality of the application from the child’s point of view. Parent feedback about their child’s experience was elicited via survey. Results There was strong inter-rater reliability in the telehealth and face-to-face conditions (correlation coefficients ranged from r = 0.96–1.0 across the subtests) and good agreement on all measures. Similar levels of attention, distractibility and anxiety were observed in the two conditions. Clinicians rated only one session of 23 as having poor audio quality and no sessions were rated as having poor visual quality. Parent and child reactions to the use of telehealth were largely positive and supportive of using telehealth to assess rural children. Discussion The findings support the use of telehealth in the language assessment of school-aged children using a web application and commercially available computer equipment. This reliable and innovative service delivery model has the potential to be used by speech pathologists to provide assessments to children in remote communities.

Full textAbstract:
The article describes an experimental study aimed at determining the effectiveness of the use of media in the formation of foreign language communicative competence of future primary school teachers on the example of the discipline "Foreign language education: a foreign language with teaching methods." The concept of "media" is considered as objects, equipment and materials that ensure the functioning of the media information space in the form of audio, visual, audio and visual messages and are allocated by the teacher to organize an active process of learning a foreign language. It is noted that the choice of media was in accordance with the practical objectives of the training sessions. The procedural and effective components of the ascertaining and forming stages of the experiment are analyzed. It is noted that the developed diagnostic tools allowed to conduct diagnostic testing, to determine insufficiently formed foreign language communicative competence of future primary school teachers and to update the formative experiment to test the effectiveness of media in foreign language teaching. It is noted that the content of the discipline was updated with topics, issues related to the analysis, evaluation and use of various types of media, which contributed to the use of modern teaching methods and technologies. A comprehensive survey of students on their awareness of the impact of media on the effectiveness of learning a foreign language and the formation of their media skills is also analyzed. The dynamics of the levels of formation of foreign language communicative competence of future primary school teachers, that also affected the quality of student achievement is demonstrated in the paper.

Full textAbstract:
Advancements in information and instruction technology have led to the evolution of a new type of classroom referred to as “smart classrooms”. These have enhanced audio-visual equipment, computers and seating layouts designed to facilitate interactive learning. Placement of different sound-absorbing finishes in an efficient manner improves the listening conditions within the classroom and reduces the amplification of internally generated noise such as that from computers and instructional equipment. This study investigates the best overall configuration of sound-absorbing material placement and characteristics of surface treatment in an attempt to enhance the listening conditions in smart classrooms. A typical layout of a smart classroom was modeled and simulated using room acoustics computer modeling. Acoustics indicators such as Reverberation Time (RT), Sound Clarity (C50) and Speech Transmission Index (STI) were used for comparing alternative cases in optimising sound-absorbing material characteristics and placement. Additionally, measurements were conducted in similar classrooms to assess the magnitude and characteristics of generated noise. To determine the impact of the resulting background noise simulations were carried out. The resulting configuration of sound-absorbing material for a typical smart classroom can also be utilized by architects and educational institutions to enhance the acoustics of existing conventional classrooms in the process of being converted or upgraded.
