Pyrolyzed Silk Carbon Fabric-Enabled Wearable Functional Actuators With Heating and Sound-Emitting Capabilities

Textile-based wearable electronics are widely favored by researchers due to their superior comfort. However, there are few studies on textile-based flexible actuators with multiple uses. In this article, a highly flexible actuator with heating and sound-emitting capabilities enabled by pyrolyzed silk carbon fabrics is developed. The functionalized fabrics with ideal physical properties are prepared by a high-temperature reduction method, which is simple and efficient. Its electrothermal and photothermal effects endow the device with heating function. The steady-state temperature can reach 188 °C and 280 °C under 0.80-W/cm2 electricity power density and 1.46-W/cm2 laser power density with high stability, respectively. By taking advantage of thermoacoustic effect, it can also produce intuitive sound messages. Test results show that acoustic properties are in good agreement with theoretical model. The output sound pressure level can be stabilized at about 55 dB in the range of 8–20 kHz under 101-mW power. The actuator carries great potentials in wearable thermal and acoustic applications.

MUSIC RADIO RECORDINGS AS OBJECTS OF THE ARCHIVAL STORAGE

The purpose of the article is to characterize the peculiarities of organizing the storage of musical audio recordings in the repositories of radio stations. The methodology is based on the use of general scientific and special methods. The universal nature of music as a special language determines the internationality of music art. From the moment of birth and during the past years verbal report of the unwritten conditions, that are connected to music sound record accumulation in different cultural institutions, has changed not once. The transformations of this relationship were caused by different reasons – social, political, technical, and technological nature. In current high-technology conditions integration properties inherent in the holistic process of creation, circulation, and spread of information, accumulated in music compositions for radio. Today the formation of the new qualitative communication area with the rapid growth of the sound messages streams level occurs. The article is dedicated to the scientific problem of the preservation and use of music audio recordings of radio companies as objects of archival storage. Archived musical radio records are defined as a special cluster of the communication area. The socio-communicative approach is the methodological basis of the publication. The scientific novelty. The main directions of ensuring the preservation, restoration, and restoration of music audio recordings of archival audio recordings are substantiated, as well as the peculiarities of digitization and use of sound documents of this type, are revealed. The specifics of the formation of the respective collections are considered on the example of the BBC Archive Center and The British Library Sound Archive as leading foreign institutions where music records are stored. It is concluded that digital technologies have led to a change in the culture of music consumption and, accordingly, have transformed the processes of storing music archival recordings in the repositories of radio companies, which have acquired specific properties. Examining music radio recordings as archival objects have shown that in the age of the digital revolution, the music industry around the world has undergone significant changes. Both the revenue structure and the cost structure of record labels and music radio companies have fundamentally changed. Conclusions. Digital technologies have led to a change in the culture of music consumption (there has been a change in the ideology of authorship for music products) and the emergence of digital recording technologies that use artificial intelligence, digital workstations, etc. In this regard, the specifics of the organization of storage of music archival recordings were transformed, in particular in the phono repositories of radio companies that have acquired specific properties of the service grade (reprint of archival music recordings that were previously specially recorded for radio stations).

Identification of a new acoustic sound field trend in modern catholic churches

This work describes the sound field transformation in catholic churches up today, focusing on a new possible acoustic trend in modern buildings.In the past, the sacred sense inside a church was greatly reinforced by the surrounding atmosphere of a very reverberant space, with possible echoes, that infatuated the perception of God and his presence. On the contrary, nowadays, concentration and intimacy are preferred.Modern Church buildings have become acoustically complex places. They are complex from the geometric point of view, because their dimensions and shapes may be extremely varied, passing from simple auditorium-like churches to complicated ones characterized by curved walls, side chapels, vaults which often act as partially coupled volumes. The range of the possible sound messages is also extremely varied passing from the spoken word to congregational singing and sometimes to organ music during the same liturgical service.In this paper some main recommendations to follow in the acoustic design of new catholic churches are presented, explaining two case studies in detail: the Santa Gianna Beretta Molla Church in Trezzano, Milan (IT) and the Massimiliano Kolbe Church in Bergamo (IT).Room Acoustics procedures and implementations of computer simulation techniques are included. A new approach for the acoustic design is proposed in which the acoustic response is suitable for both speech and music as recent room acoustics’ studies for other typologies of building such as theatres and multipurpose auditoria suggest.

INFLUENCE OF SOCIAL NETWORK DEPENDENCY ON PERCEPTION OF PUBLIC SPACE OF THE CITY.

Throughout history, it has always been important for a person to believe in something and be dependent on something (be it a religion, a cult, a group of like-minded people, virtual popularity, rules of video games, etc.). It created a protective effect, gave a sense of involvement (overcoming loneliness) and developed self-confidence. At the same time, this phenomenon turned into emotional dependence and stimulated the person to perform a certain set of actions to get a portion of emotions.At the beginning of the 21st century, over 3 billion people (40% of the population) use virtual public space to communicate with each other [5]. Accordingly, the real public spaces of cities are experiencing decadence. Decadence manifests itself precisely in information that carries space.An individual, moving around the city, is concentrated mainly on himself or in the virtual world in his smartphone. Morover, he is constantly in a hurry and has no time. All the services that he used to apply for here, in this square, are now in his hand and are carried out with one click on the screen. The exchange of emotions and impressions between friends and relatives more and more often takes place in video messages, sound messages, or in chat rooms, using stamped animoji and gifs. The opinion of an authoritative intelligent person is also no longer the subject of a search in a cafe (as in times of “ penny universities”), since more than half of people have a social network profiles and are willing to communicate with you in virtual space. Furthermore, social networks give fast virtual love and attention from completely strangers, something that people have been working on for a long time and which they deserve for years in real life. A successful photo or text and commenting on it, cause an emotional “pat”, which physiologicaly can replace hugs and meeting with friends in a public space.In this context, modern city spaces with eternal haste, annoyed people, public transport, buzzing sounds and unpleasant smells cause stress and desire to rather cross them, or again return to virtual space. Public spaces are gradually losing their communicative function.The leading direction of projects that win the European Public Prize for urban space [7] shows that developers in recent years have been interested in transforming historic, locally known public spaces into open-air museums or so-called “Instagram spaces ".Do not forget about the dependence on video games, which in 2018 officially received the status of a mental disorder.Virtual, painted public spaces in video games, drawing inspiration from very real urban spaces, for people suffering from video-gambling addiction, over time replace the physically tangible ones.Caused by changes in technological culture and the emergence of new emotional dependencies, the style of behavior and lifestyle of modern man is also undergoing changes. These changes are neither good nor bad in substance, but rather a natural process of development. Most importantly, from the point of view of the urbanist- architect, is the realization that the appearance, filling and content of public spaces of cities is transforming. Some features are gradually dying out of their own necessity and other appearing, making the public space interesting for a city dweller already with a set of other emotional dependencies.

The Significance of the Process of Music Therapy for Children with Multiple Social and Communication Disabilities

Music therapy is an interdisciplinary branch of science and a form of therapy which enables establishing contact with every human being by means of an aesthetic sound message. The aim of this paper is to present the influence of music therapy procedures on communicative and social areas of the development of children with multiple disabilities, namely two boys. Moreover, the research activity is also concentrated on the ways music influences particular cases, namely which chosen music therapy strategies. The article presents individualizing research in a qualitative dimension. The outline of the research project is presented with its problem matters, research objectives, methods (of individual case study), and research techniques, as well as a detailed description of the research tool - The Individualized Music Therapy Assessment Profile (IMTAP) recommended by the American Music Therapy Association (AMTA). The results presented in a detailed description and observation schedule as well as data collected from interviews demonstrates and, at the same time, answers the research question that music therapy is a useful and effective form of therapy in the case of two boys with multiple disabilitities – to improve social and communicative functioning of the their development.

Análisis acústico del Auditório Padre Werner em Unisinos

The acoustic quality in enclosed spaces is defined by the constructive characteristics of the environment, which must be designed to increase the propagation of the sound. Therefore, the sound message to be transmitted, whether spoken, song or by music instruments, can be intelligibly captured by the listeners. Among the main characteristics that influence the sound behavior in rooms are its dimensions, its geometric shape and the finishing materials applied on their internal surfaces. Each room has different acoustic requirements, directly related to the purpose for which it is intended. Therefore, the professional responsible for the design and construction of these environments should analyze and recognize the needs of each case. In this way, the present case study presents the evaluation of the acoustic quality of a multiple use auditorium, at Unisinos Campus, in Sao Leopoldo, southern Brazil. Acoustic measurements were performed to calculate the Reverberation Time (T30) and the Early Decay Time (EDT) of the room. Afterwards, the modelling of the auditorium in the acoustic simulation software CATT-Acoustics was carried out, allowing the estimation of other objective acoustic parameters such as the Speech Transmission Index (STI), Definition (D50) and Clarity (C80). The results obtained through measurements and acoustic simulations show that the auditorium has satisfactory acoustic quality for speech, but it is not so suitable for receiving musical presentations. The model generated in the software also made it possible to simulate constructive solutions aiming to improve the acoustic quality of the room.

Rádio e inclusão: uma análise de experiências de rádio para surdos em portugal

A rádio adquiriu um conjunto de novas ferramentas em virtude da sua migração para as plataformas digitais e, em concreto, para a Internet. Como defendem vários autores, falar hoje de rádio, significa considerar este como um meio multimedia e multiplataforma. A partir deste pressuposto, abrem-se novos caminhos para a rádio, quer no que toca ao acesso, quer em relação à captação de novos públicos que estavam afastados deste meio. A comunidade surda integrava naturalmente esse público incapacitado para escutar mensagens exclusivamente sonoras. Cenário que se alterou com esta “nova rádio”. Em 2005 e 2013 a TSF e a Antena 1, respetivamente, realizaram duas emissões de rádio com tradução para Língua Gestual Portuguesa. O presente artigo procura analisar essas duas experiências e lançar uma reflexão sobre o papel da rádio enquanto meio de inclusão da pessoa com deficiência e em particular dos surdos.

Variation of Some Water Quality Parameters from Winter to Summer Period in Chittagong Karnafully River of Bangladesh

A study has been conducted to investigate the variation of water quality parameters during January to June of 2014 in Karnafully River of Chittagong, Bangladesh. Water samples were collected from January to June 2014 of each month in 5th day. Samples of water from three points of Karnafully Rive were collected and brought in laboratory for analysis and analyzed by using different standard prescribed methods. Total eight water quality parameters were measured like as pH, EC, TDS, Total Hardness, Fe, Cl-, As and Turbidity. All the water quality parameters were attenuated from January (winter) to June (summer) except pH. Another important fact was most of the parameter’s values exceeded the permissible limit recommended by WHO. It is a concerning event for ecology and environment of this catchment area. Our findings will convey a sound message for the government body and policy maker to set up rules and regulation in order to keep ecological balance as well as save our environment and this research will be helpful for public awareness. An immediate attention from the concerning body is mandatory in order to protect the aquatic environment of Karnafully River as well as food chain contamination.

Repeated exposures and child centered nutrition phrases increases young children’s consumption and liking of lentils

BackgroundUse of repeated exposure in fostering development of food preferences has been examined; however, other techniques such as adult verbal communication have not. Child centered nutrition phrases (CCNP) have been developed, but the efficacy of adults’ use of these developmentally appropriate, nutritionally sound messages to improve children’s intake and liking of lentils has not been evaluated. ObjectiveTo determine whether repeated taste exposure (RE) and RE+CCNP would increase young children’s liking and intake of lentils. MethodsChildren (3–6 y; n=29) were offered lentils on 14 occasions (baseline, 12 exposures, and post). Taste preference and consumption were recorded and lentil consumption was measured to the nearest 0.1g. A generalized linear model was used to assess the potential group (RE or RE+CCNP) by exposure interaction on the proportional intake (weight eaten divided by weight offered). A subsequent logistic regression analysis was carried out to estimate the change in the odds of children reporting liking in the RE+CCNP group compared to the RE group. ResultsChildren’s consumption and liking of lentils increased with repeated exposure. Children exposed to CCNPs consumed a greater amount of lentils, although it was not statistically significant; however their reported liking at the beginning (p=0.04) and intermediate (p=0.02) time periods was more frequent than children who did not receive CCNP. ConclusionsRepeated taste exposure resulted in increased liking and intake of lentils in young children, and the use of CCNP may facilitate children’s liking and intake of certain foods.

La estructura emocional del mensaje publicitario en radio

La publicidad radiofónica sufre una evidente crisis de creatividad al no haber encontrado su acomodo en un modelo de radio basado en la locución y el género informativo. Este artículo plantea la necesidad de utilizar la ruta periférica o heurística para captar y mantener la atención del receptor. En este marco, se propone la narrativa y la escenificación dramática como técnica persuasiva eficaz. El objetivo es diseñar una herramienta conceptual que pueda ser útil para idear una narración sonora al servicio de una determinada estrategia comercial. En primer lugar, se hace una revisión del poder persuasivo de la narración según las posibilidades del código sonoro. En segundo lugar, se desarrollan las claves escénicas y publicitarias (marca, producto, ventaja, beneficio y target) del mensaje sonoro. Y en tercer lugar, estas claves se incorporan en un modelo cuyo funcionamiento es pretestado mediante ocho casos de diferentes cuñas.

Fighting Skin Cancer With a Musical Sound

Australian youth have good knowledge about skin cancer prevention as a result of over three decades of traditional mass media campaigns. However, youth sun protection behavior remains poor. This case study describes the results of a unique social marketing campaign (the Sun Sound) aimed at translating youths’ knowledge into improved sun protection behavior. Formative research identified that a key barrier to sun protection was youth regularly forgot to protect their skin. As such, the campaign centered on a musical jingle that was broadcast at outdoor recreational settings as a “cue to action” reminder to use sun protection at the time and point of sun exposure. The Sun Sound was trialed at two coastal communities in New South Wales, Australia, during summer 2009–2010. The media launch generated 17.6 million Australian audience impressions (advertising value A$257,785). Intercept surveys conducted with 467 youth aged 12–18 years found there was high unprompted recall (41%) and understanding (79%) of the Sun Sound message. The Sun Sound was found to be an effective cue to action in prompting sun protection behaviors when heard, with over a third (38%) of respondents reporting use of additional sun protection upon hearing the jingle. Since the pilot, the Sun Sound has expanded to over 60 pools, beaches, and selected venues across Australia. The campaign demonstrates it is possible to influence behavior by targeting audiences at the actual point that behavior occurs, using research-informed insights and a relevant marketing mix.

Keep your postprandial curve flat

Post-prandial glycaemia and triglyceridemia increase should be kept low. This is one of the sound messages that emerge from the recent research in metabolism and nutrition. In fact, low glycaemia and lipemia post-prandial levels are associated with lower use of glucose and triacylglycerols for the synthesis of storage fat, lower oxidative stress, and lower inflammatory response. These actions play positive roles in the prevention and control of the metabolic and degenerative disorders typical of modern societies. How can we keep low post-prandial glycaemia and lipemia responses? The most immediate approach is the choice of low-glycemic index foods. An International group of experts met in Stresa (Italy) from June 5th to June 7th and redacted a consensus document (which can be downloaded at http://www.nutrition-foundation.it/convegni/glycemic-index-summit-2013.php) in which they underscore how the isocaloric substitution of high-glycemic index foods with low-glycemic index ones is easy and effective. Italian-style pasta, as an example (and specifically spaghetti, if not overcooked, i.e. “al dente”), induces post-prandial glycemic curves that are flatter, and reach lower peaks, as compared with bread and – even more so – with standard potatoes. Indeed, the European Food Safety Authority (EFSA) acknowledges that a low glycemic response is advantageous for the consumer and that food items with these features can bear specific health claims. Another possibility to keep low post-prandial glycaemia and triglyceridemia is the use of food items obtained from plants (popular with some ethnic groups) that can favorably influence the glycemic response to a meal, via multiple mechanisms. A paper from Indian authors underscores the role of a tropical legume (“horse gram”) in the control of post-prandial glycemia (curiously, the sprouts of this plant, now more and more used in the area, are less effective than unprocessed seeds of the plant); a paper from Mexico, on the other hand, shows the favorable effects of infusions prepared from local herbs (Hypericum and Salvia) on insulin sensitivity in a rat model, which should translate also into a better handling of food carbohydrates. Keeping the post-prandial curves as flat as possible: this is one of the goals that should be jointly addressed by food technologists, biochemists, and nutritionists. Notably, food companies should also pay more attention to this important issue.

El complejo salto de la radio convencional a la webradio. Usos y percepciones de los universitarios

El traspaso de la radiofonía hertziana a la webradio ha supuesto una reconfiguración de los contenidos radiofónicos más allá del ámbito estrictamente sonoro.

Cancer survivors: familial risk perception and management advice given to their relatives

The aim of this study was to describe 2 years cancer survivors' perception of the cancer risk running in their family, and to describe how frequently these survivors recommended cancer screening to their relatives. A national cross-sectional survey was launched by the French Ministry of Health to investigate the living conditions of adult cancer patients 2 years after cancer diagnosis. Among the 13,923 patients identified, 6,957 were eligible to participate in this study and 4460 (64.1%) answered the questionnaire administered by telephone. One participant out of every two (50.8%) reported that they thought their relatives' risk of cancer was greater than that of the relatives of unaffected persons. Higher percentages were recorded among breast and colorectal cancer patients (65 and 65.1%, respectively), and lower percentages among those with lung and hematological cancer (34.9 and 28.4%, respectively). Overall, 61.1% of the participants had already advised relatives to undergo cancer screening and 10.4% planned to do so. Eighty-one percent of the participants with breast cancer and 76.3% of those with colorectal cancer said they had advised relatives to undergo screening. Lower percentages were obtained among patients with urinary tract (41.7%) and hematological malignancies (27.1%). Although patients' perceptions tend to fit the latest data on the frequency of cancer germline mutations, physicians should help their patients to convey more accurate advice to their families. If survivors were better informed, they could play a critical role by conveying relevant and sound risk reduction messages to their relatives.

′Cinemadness′: In search of sanity in films

Byline: G. Swaminath, Ajit. Bhide The Camera Never Lies,But What About the Film Maker ? Dr. Ashok Pai, a veteran psychiatrist and a film script writer and producer, from the once sleepy town of Shimoga in Karnataka, made some astute observations on the strange story-telling in some highly successful 'action films'. The secret agent enters the villain's den and finds himself in a dingy warehouse stacked with gunnysacks full of a whitish powder. Dipping his finger into one of them, he licks it and exclaims, "Uranium!" This fills the minds of audience with horror about the audacity of the unseen villain and his capacity to amass ingredients of mass destruction. Very few among the audience reflect on the important scientific issues related to this scene. For example, can uranium, a dangerous radioactive chemical, be stored in gunnysacks? Will not such storage create havoc across miles, most impo rtantly for the nearby goons on whose strength the villain rules? Will any intelligent person, especially a secret agent, ever put his finger into an unknown substance and lick it as a means of identification? And finally, how come a radioactive element when licked does not produce devastating effects on the hero? Cinema in general and Indian cinema in particular has a fantastic disconnectedness from reality. Are there really beautiful 20-year-old blonde nuclear scientists wandering in bikinis in their labs?[sup] [1] Is there a 20-year-old petite neurosurgeon as portrayed in the movie Kambakt Ishq? Do terrorists really build bombs with convenient displays that inform us how much time we have to deactivate the contrivance?[sup] [1] Do men and women in Indian villages really run around trees, singing songs of undying love with a full orchestra playing in the background? Are the police always corrupt and incompetent?[sup] [1] These questions never arise in the audience's mind as the sole purpose of the audience in viewing the film is to drown in fantasy while being entertained. Unfortunately, such crass fare is served to pass for 'wholesome entertainment.' Many, who understand the irrationalities of a scene, are willing to suspend logical judgment and even accept it as artistic license. The rest, who fail to understand this, take back the message that uranium can be stored in gunnysacks and such associated irrationalities. This shapes their knowledge, their attitude and perception of issues related to uranium. The power of the medium can never be overestimated. The passive acceptance of irrational ideas, as in the scene described above, does not necessarily affect society at large in any measurable way, given the remoteness of the chances of the average moviegoer coming into contact with anything related to nuclear physics. However, the same stance cannot be taken with regard to sensitive issues, such as mental illness. Owing to their sheer novelty and the mystic element, psychological issues, mental illness and the mentally ill occupy an important place in the minds of film makers. Films on issues related to mental illness have been box office hits, and we would reckon that they feature at least among the top 50 films of all time in any language. This repeated portrayal of the mentally ill and mental illness with the usual distortions has contributed a lot to the stigma and burden which the mentally ill and their caretakers have to bear. Time to Change It is now time to change. And heralding this is a remarkable effort by a leading psychiatrist, Dr. Peter Byrne, a researcher in the field of stigma of mental illness; and a film expert, Sue Baker, who have started Time to Change, an advocacy group. Their slogan is, "Let's end mental health discrimination."[sup] [2] Dr. Byrne has brought out a report, Screening Madness, which analyzes the contributions of cinema in influencing public perception and attitudes positively or otherwise.[sup] [2] The report states that characters with mental health problems are being depicted as "more demonic and crueler than at any time in movie history. …
