    The aging population has inspired the marketing of advanced real time devices for home health care, more and more wearable devices and mobile applications, which have emerged in this field. However, to properly collect behavior information, accurately recognize human activities, and deploy the whole system in a real living environment is a challenging task. In this paper, we propose a feasible wireless-based solution to deploy a data collection scheme, activity recognition model, feedback control and mobile integration via heterogeneous networks. We compared and found a suitable algorithm that can be run on cost-efficient embedded devices. Specifically, we use the Super Set Transformation method to map the raw data into a sparse binary matrix. Furthermore, designed front-end devices of low power consumption gather the living data of the habitant via ZigBee to reduce the burden of wiring work. Finally, we evaluated our approach and show it can achieve a theoretical time-slice accuracy of 98%. The mapping solution we propose is compatible with more wearable devices and mobile apps.

    The VitalPoll Telemedicine System (VTS) was designed and developed for wireless home healthcare. The aims of this study were: to design the architecture and communication methods for a telemedicine system; to implement a physiologic routing hub to collect data from different medical devices and sensors; and to evaluate the feasibility of this system for applications in wireless home healthcare. The VTS was built using Bluetooth wireless and Internet technologies with client/server architecture. Several medical devices, which acquire vital signs, such as real-time electrocardiogram signals, heart rate, body temperature, and activity (physical motion), were integrated into the VTS. Medical information and data were transmitted over short-range interface (USB, RS232), wireless communication, and the Internet. The medical results were stored in a database and presented using a web browser. The patient's vital signals can be collected, transmitted, and displayed in real time by the VTS. The experiments verified no data loss during Bluetooth and Internet communication. Bluetooth and the Internet provide enough bandwidth channels to tranmit these vital signs. The experimental results show that VTS may be suitable for a practical telemedicine system in home healthcare.

    Directory of Open Access Journals (Sweden)

    Hong SeungHo

    2011-01-01

    Full Text Available The use of wireless sensor networks in home automation (WSNHA is attractive due to their characteristics of self-organization, high sensing fidelity, low cost, and potential for rapid deployment. Although the AODVjr routing algorithm in IEEE 802.15.4/ZigBee and other routing algorithms have been designed for wireless sensor networks, not all are suitable for WSNHA. In this paper, we propose a location-based self-adaptive routing algorithm for WSNHA called WSNHA-LBAR. It confines route discovery flooding to a cylindrical request zone, which reduces the routing overhead and decreases broadcast storm problems in the MAC layer. It also automatically adjusts the size of the request zone using a self-adaptive algorithm based on Bayes' theorem. This makes WSNHA-LBAR more adaptable to the changes of the network state and easier to implement. Simulation results show improved network reliability as well as reduced routing overhead.

    Issa Ahmed, Rudhwan

    There are several techniques that have been implemented for smart homes usage; however, most of these techniques are limited to a few sensors. Many of these methods neither meet the needs of the user nor are cost-effective. This thesis discusses the design, development, and implementation of a wireless network system, based on multi-non-invasive sensors for smart home environments. This system has the potential to be used as a means to accurately, and remotely, determine the activities of daily living by continuously monitoring relatively simple parameters that measure the interaction between users and their surrounding environment. We designed and developed a prototype system to meet the specific needs of the elderly population. Unlike audio-video based health monitoring systems (which have associated problems such as the encroachment of privacy), the developed system's distinct features ensure privacy and are almost invisible to the occupants, thus increasing the acceptance levels of this system in household environments. The developed system not only achieved high levels of accuracy, but it is also portable, easy to use, cost-effective, and requires low data rates and less power compared to other wireless devices such as Wi-Fi, Bluetooth, wireless USB, Ultra wideband (UWB), or Infrared (IR) wireless. Field testing of the prototype system was conducted at different locations inside and outside of the Minto Building (Centre for Advanced Studies in Engineering at Carleton University) as well as other locations, such as the washroom, kitchen, and living room of a prototype apartment. The main goal of the testing was to determine the range of the prototype system and the functionality of each sensor in different environments. After it was verified that the system operated well in all of the tested environments, data were then collected at the different locations for analysis and interpretation in order to identify the activities of daily living of an occupant.

    Wireless sensor networks (WSNs) provide noteworthy benefits over traditional approaches for several applications, including smart homes, healthcare, environmental monitoring, and homeland security. WSNs are integrated with the Internet Protocol (IP) to develop the Internet of Things (IoT) for connecting everyday life objects to the internet. Hence, major challenges of WSNs include: (i) how to efficiently utilize small size and low-power nodes to implement security during data transmission among several sensor nodes; (ii) how to resolve security issues associated with the harsh and complex environmental conditions during data transmission over a long coverage range. In this study, a secure IoT-based smart home automation system was developed. To facilitate energy-efficient data encryption, a method namely Triangle Based Security Algorithm (TBSA) based on efficient key generation mechanism was proposed. The proposed TBSA in integration of the low power Wi-Fi were included in WSNs with the Internet to develop a novel IoT-based smart home which could provide secure data transmission among several associated sensor nodes in the network over a long converge range. The developed IoT based system has outstanding performance by fulfilling all the necessary security requirements. The experimental results showed that the proposed TBSA algorithm consumed less energy in comparison with some existing methods. PMID:28042831

    Wireless sensor networks (WSNs) provide noteworthy benefits over traditional approaches for several applications, including smart homes, healthcare, environmental monitoring, and homeland security. WSNs are integrated with the Internet Protocol (IP) to develop the Internet of Things (IoT) for connecting everyday life objects to the internet. Hence, major challenges of WSNs include: (i) how to efficiently utilize small size and low-power nodes to implement security during data transmission among several sensor nodes; (ii) how to resolve security issues associated with the harsh and complex environmental conditions during data transmission over a long coverage range. In this study, a secure IoT-based smart home automation system was developed. To facilitate energy-efficient data encryption, a method namely Triangle Based Security Algorithm (TBSA) based on efficient key generation mechanism was proposed. The proposed TBSA in integration of the low power Wi-Fi were included in WSNs with the Internet to develop a novel IoT-based smart home which could provide secure data transmission among several associated sensor nodes in the network over a long converge range. The developed IoT based system has outstanding performance by fulfilling all the necessary security requirements. The experimental results showed that the proposed TBSA algorithm consumed less energy in comparison with some existing methods.

    Full Text Available This paper presents a home area network (HAN-based domestic load energy consumption monitoring prototype device as part of an advanced metering system (AMS. This device can be placed on individual loads or configured to measure several loads as a whole. The wireless communication infrastructure is supported on IEEE 805.12.04 radios that run a ZigBee stack. Data acquisition concerning load energy transit is processed in real time and the main electrical parameters are then transmitted through a RF link to a wireless terminal unit, which works as a data logger and as a human-machine interface. Voltage and current sensing are implemented using Hall effect principle-based transducers, while C code is developed on two 16/32-bit microcontroller units (MCUs. The main features and design options are then thoroughly discussed. The main contribution of this paper is that the proposed metering system measures the reactive energy component through the Hilbert transform for low cost measuring device systems.

    In order to estimate typical radio frequency exposures from indoor used wireless communication technologies applied in homes and offices, WLAN, Bluetooth and Digital Enhanced Cordless Telecommunications systems, as well as baby surveillance devices and wireless headphones for indoor usage, have been investigated by measurements and numerical computations. Based on optimised measurement methods, field distributions and resulting exposure were assessed on selected products and real exposure scenarios. Additionally, generic scenarios have been investigated on the basis of numerical computations. The obtained results demonstrate that under usual conditions the resulting spatially (over body dimensions) averaged and 6-min time-averaged exposure for persons in the radio frequency fields of the considered applications is below ∼0.1% of the reference level for power density according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines published in 1998. Spatial and temporal peak values can be considerably higher by 2-3 orders of magnitude. In case of some transmitting devices operated in close proximity to the body (e.g. WLAN transmitters), local exposure can reach the same order of magnitude as the basic restriction; however, none of the devices considered in this study exceeded the limits according to the ICNIRP guidelines.

    Brain Computer Interface (BCI) based environment control systems could facilitate life of people with neuromuscular diseases, reduces dependence on their caregivers, and improves their quality of life. As well as easy usage, low-cost, and robust system performance, mobility is an important functionality expected from a practical BCI system in real life. In this study, in order to enhance users' mobility, we propose internet based wireless communication between BCI system and home environment. We designed and implemented a prototype of an embedded low-cost, low power, easy to use web server which is employed in internet based wireless control of a BCI based home environment. The embedded web server provides remote access to the environmental control module through BCI and web interfaces. While the proposed system offers to BCI users enhanced mobility, it also provides remote control of the home environment by caregivers as well as the individuals in initial stages of neuromuscular disease. The input of BCI system is P300 potentials. We used Region Based Paradigm (RBP) as stimulus interface. Performance of the BCI system is evaluated on data recorded from 8 non-disabled subjects. The experimental results indicate that the proposed web server enables internet based wireless control of electrical home appliances successfully through BCIs.

    2015-06-01

    Full Text Available We live in an aging society, an issue that will be exacerbated in the coming decades, due to low birth rates and increasing life expectancy. With the decline in physical and cognitive functions with age, it is of the utmost importance to maintain regular physical activity, in order to preserve an individual’s mobility, motor capabilities and coordination. Within this context, this paper describes the development of a wireless sensor network and its application in a human motion capture system based on wearable inertial and magnetic sensors. The goal is to enable, through continuous real- time monitoring, the creation of a personalized home-based rehabilitation system for the elderly population and/or injured people. Within this system, the user can benefit from an assisted mode, in which their movements can be compared to a reference motion model of the same movements, resulting in visual feedback alerts given by the application. This motion model can be created previously, in a ‘learning phase’, under supervision of a caregiver.

  11. IDEOLOGICALLY CHALLENGING ENTERTAINMENT (ICE

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Ideologically Challenging Entertainment (ICE is entertainment that challenges ‘us vs. them’ ideologies associated with radicalization, violent conflict and terrorism. ICE presents multiple perspectives on a conflict through mainstream entertainment. This article introduces the theoretical underpinnings of ICE, the first ICE production and the audience responses to it. The first ICE production was Two Merchants: The Merchant of Venice adapted to challenge ideologies of the Arab-Israeli Conflict. A mixed-methods study of audience responses explored whether this production inspired audiences to shift their ideological views. Each performance included two versions of the adaptation: a Jewish dominated society with an Arab Muslim minority, contrasted with an Arab Muslim dominated society and a Jewish minority. A mixed-methods study of audience responses explored whether this production inspired audiences to shift their ideological views to become more tolerant of differences away from ideological radicalization. Of audience members who did not initially agree with the premise of the production, 40% reconsidered their ideological views, indicating increased tolerance, greater awareness of and desire to change their own prejudices. In addition, 86% of the audience expressed their intention to discuss the production with others, thereby encouraging critical engagement with, and broader dissemination of the message. These outcomes suggest that high quality entertainment – as defined by audience responses to it - can become a powerful tool in the struggle against radicalised ideologies.

    2005-09-01

    A point-of-care system for continuous health monitoring should be wearable, easy to use, and affordable to promote patient independence and facilitate acceptance of new home healthcare technology. Reconfigurability, interoperability, and scalability are important. Standardization supports these requirements, and encourages an open market where lower product prices result from vendor competition. This paper first discusses candidate standards for wireless communication, plug-and-play device interoperability, and medical information exchange in point-of-care systems. It then addresses the design and implementation of a wearable, plug-and-play system for home care which adopts the IEEE 1073 Medical Information Bus (MIB) standards, and uses Bluetooth as the wireless communication protocol. This standards-based system maximizes user mobility by incorporating a three-level architecture populated by base stations, wearable data loggers, and wearable sensors. Design issues include the implementation of the MIB standards on microcontroller-driven embedded devices, low power consumption, wireless data exchange, and data storage and transmission in a reconfigurable body-area network.

    Brain-computer interface (BCI) system is a system that achieves communication and control among humans and computers and other electronic equipment with the electroencephalogram (EEG) signals. This paper describes the working theory of the wireless smart home system based on the BCI technology. We started to get the steady-state visual evoked potential (SSVEP) using the single chip microcomputer and the visual stimulation which composed by LED lamp to stimulate human eyes. Then, through building the power spectral transformation on the LabVIEW platform, we processed timely those EEG signals under different frequency stimulation so as to transfer them to different instructions. Those instructions could be received by the wireless transceiver equipment to control the household appliances and to achieve the intelligent control towards the specified devices. The experimental results showed that the correct rate for the 10 subjects reached 100%, and the control time of average single device was 4 seconds, thus this design could totally achieve the original purpose of smart home system.

    Full Text Available Omega-3 polyunsaturated fatty acids (n-3 PUFAs enriched eggs are popular for their enrichment of PUFAs, but their freshness and quality are prone to decline with time, particularly if storage conditions are not well maintained. Home storage is the last but a neglected important tach in eggs supply chain, but few studies are available on the egg storage in the home stage. This study aimed to evaluate the internal quality change of both n-3 PUFAs enriched and conventional eggs by simulating eggs stored at consumers’ home in refrigeration and under room temperature. The egg quality indices (Haugh unit, yolk index, weight, and albumen pH were adopted and analyzed for both storage conditions. Wireless sensor network (WSN was used for real-time monitoring of the temperature and humidity during storage. The results showed that temperature, humidity and time of storage all have an influence on the freshness of both n-3 PUFAs enriched and conventional eggs and there is no significant difference happened to n-3 PUFAs enriched eggs and conventional eggs. Refrigeration can decelerate the quality deterioration of both n-3 PUFAs enriched and conventional eggs and consumers should be educated about how to maintain the internal quality of eggs during home storage.

    A project was developed for the creation of an Internet-based network aimed at improved management of home care activities in brain-injured children. At the patient's side, a home care unit was provided, made of a portable medical device, and a tablet PC. Measured clinical data were blood oxygen saturation, heart rate, breath rate and quantity of movement. Thanks to device portability, the patient was free to move while measurements were taken. At prescribed time intervals, measured data were automatically transmitted to the tablet PC via Bluetooth. From the tablet PC, data were transmitted remotely to a Service Centre (via ADSL or GPRS) and made available for consultation by health care professionals through the project Web portal. At the portal, other functionalities were also available, both for patients and families, and for professionals (such as weekly planning agenda, access to relevant information resources, communication tools). Information was delivered for the right participant through a workflow engine. A first trial involving nine patients was performed for two months. At the end, although some improvements were suggested, good acceptance was detected, and 78% of patients and families claimed to be interested in further use of the platform.

    Full Text Available Evil-Twin is becoming a common attack in smart home environments where an attacker can set up a fake AP to compromise the security of the connected devices. To identify the fake APs, The current approaches of detecting Evil-Twin attacks all rely on information such as SSIDs, the MAC address of the genuine AP, or network traffic patterns. However, such information can be faked by the attacker, often leading to low detection rates and weak protection. This paper presents a novel Evil-Twin attack detection method based on the received signal strength indicator (RSSI. Our approach considers the RSSI as a fingerprint of APs and uses the fingerprint of the genuine AP to identify fake ones. We provide two schemes to detect a fake AP in two different scenarios where the genuine AP can be located at either a single or multiple locations in the property, by exploiting the multipath effect of the Wi-Fi signal. As a departure from prior work, our approach does not rely on any professional measurement devices. Experimental results show that our approach can successfully detect 90% of the fake APs, at the cost of a one-off, modest connection delay.

    2013-11-01

    Full Text Available The analysis of human behavior patterns is increasingly used for several research fields. The individualized modeling of behavior using classical techniques requires too much time and resources to be effective. A possible solution would be the use of pattern recognition techniques to automatically infer models to allow experts to understand individual behavior. However, traditional pattern recognition algorithms infer models that are not readily understood by human experts. This limits the capacity to benefit from the inferred models. Process mining technologies can infer models as workflows, specifically designed to be understood by experts, enabling them to detect specific behavior patterns in users. In this paper, the eMotiva process mining algorithms are presented. These algorithms filter, infer and visualize workflows. The workflows are inferred from the samples produced by an indoor location system that stores the location of a resident in a nursing home. The visualization tool is able to compare and highlight behavior patterns in order to facilitate expert understanding of human behavior. This tool was tested with nine real users that were monitored for a 25-week period. The results achieved suggest that the behavior of users is continuously evolving and changing and that this change can be measured, allowing for behavioral change detection.

    The effective care and support of community healthcare nurses (CHNs) contribute greatly to the healthy aging of older adults living at home. Integrating innovative technologies into CHNs' daily practice offers new opportunities and perspectives for early detection of health issues and interventions among home-dwelling older adults. To explore the perception of acceptability among CHNs of an intelligent wireless sensor system (IWSS) for use in daily practice for the detection of health issues in home-dwelling older adults receiving home healthcare. Descriptive and qualitative data were sourced from a pilot randomized controlled trial involving 17 CHNs using an IWSS in their daily practice to rapidly detect falls and other health issues in patients' homes. IWSS alerts indicating behavior changes were sent to CHNs. Their perceived usefulness (PU) and perceived ease of use (PEOU) were assessed. The acceptability of IWSS technology was explored using a questionnaire and focus group discussions. The PU and PEOU of the IWSS technology were low to moderate. A majority of the CHNs were dissatisfied with its performance and intrusiveness; they reported multiple obstacles in the usefulness and ease of use of the IWSS technology in daily practice. To improve the IWSS technology's low to moderate acceptability among CHNs, we recommend a more user-centered implementation strategy and an embedded model of nursing care.

    2016-01-01

    This book focuses on the emerging research topic "green (energy efficient) wireless networks" which has drawn huge attention recently from both academia and industry. This topic is highly motivated due to important environmental, financial, and quality-of-experience (QoE) considerations. Specifically, the high energy consumption of the wireless networks manifests in approximately 2% of all CO2 emissions worldwide. This book presents the authors’ visions and solutions for deployment of energy efficient (green) heterogeneous wireless communication networks. The book consists of three major parts. The first part provides an introduction to the "green networks" concept, the second part targets the green multi-homing resource allocation problem, and the third chapter presents a novel deployment of device-to-device (D2D) communications and its successful integration in Heterogeneous Networks (HetNets). The book is novel in that it specifically targets green networking in a heterogeneous wireless medium, which re...

    The extensions of the environment with the integration of sensing systems in any space, in conjunction with ubiquitous computing are enabling the so-called Smart Space Sensor Networks. This new generation of networks are offering full connectivity with any object, through the Internet of Things (IoT) and/or the Web, i.e., the Web of Things. These connectivity capabilities are making it feasible to sense the behaviours of people at home and act accordingly. These sensing systems must be integrated within typical elements found at home such as furniture. For that reason, this work considers furniture as an interesting element for the transparent location of sensors. Furniture is a ubiquitous object, i.e., it can be found everywhere at home or the office, and it can integrate and hide the sensors of a network. This work addresses the lack of an exhaustive study of the effect of furniture on signal losses. In addition an easy-to-use tool for estimating the robustness of the communication channel among the sensor nodes and gateways is proposed. Specifically, the losses in a sensor network signal due to the materials found within the communication link are evaluated. Then, this work proposes a software tool that gathers the obtained results and is capable of evaluating the impact of a given set of materials on the communications. This tool also provides a mechanism to optimize the sensor network deployments during the definition of smart spaces. Specifically, it provides information such as: maximum distances between sensor nodes, most suitable type of furniture to integrate sensors, or battery life of sensor nodes. This tool has been validated empirically in the lab, and it is currently being used by several enterprise partners of the Technological Centre of Furniture and Wood in the southeast of Spain.

The study identifies entrepreneurial orientation within a defined franchise system, using the entrepreneurial character theme matrix developed by Thompson (2002. Research methodology comprises the survey approach, using electronic media and Surveypro analysis (Dillman, 2000. Hypothesis tests highlight the absence of statistically significant entrepreneurial orientation in the franchise system, despite a significant orientation in a multiple-outlet proposition analysis. Conclusions and recommendations include mobilising and communicating the action factors associated with entrepreneurial orientation, involving all franchisees within the system. Managerial implications include the motivation of developing multiple-outlet franchise systems. Future research involves broadening the data set across industries and borders.

The task has to include playful and light-hearted content. We explore some words in English that may help us to understand the concept of "scientific entertainer" from a semantic point of view (showman, master of ceremonies, entrepreneur, go-between) also in Spanish language (counsellor, mediator, methodologist) and finally in Latin and Greek (tripalium, negotium, chronos, kairos). We define the clinical, manager or research health-worker who is skilled in primary care as a "primarylogist". Copyright © 2011 Elsevier España, S.L. All rights reserved.

    Full Text Available The term Entertainment Industry has been used interchangeably with the term Creative Industries and also has been suggested to be part of the creative industries. The creative industries seeks to provide commercially viable artistic and creative products, known as intellectual property, and in the process of such provision, contributes to the nation’s creative economy. From an education perspective in Southeast Asia, two observations can be made. Firstly, the focus of education in relation to the entertainment industry has always been technical. Secondly, the introduction of the concepts of the creative industries in Southeast Asia has spurred new trends in the education of the entertainment industry. Outside of Southeast Asia, there have been a growing number of academic programs in the field of Entertainment. From within Southeast Asia, Malaysia has taken the lead to introduce two new trends in the entertainment education – entertainment management and entertainment arts.

    Laser shows and beam effects have been a source of entertainment since its first public performance May 9, 1969, at Mills College in Oakland, California. Since 1997, the Photonics Center, NgeeAnn Polytechnic, Singapore, has been using laser shows as a teaching tool. Students are able to exhibit their creative skills and learn at the same time how lasers are used in the entertainment industry. Students will acquire a number of skills including handling three- phase power supply, operation of cooling system, and laser alignment. Students also acquire an appreciation of the arts, learning about shapes and contours as they develop graphics for the shows. After holography, laser show animation provides a combination of the arts and technology. This paper aims to briefly describe how a krypton-argon laser, galvanometer scanners, a polychromatic acousto-optic modulator and related electronics are put together to develop a laser projector. The paper also describes how students are trained to make their own laser animation and beam effects with music, and at the same time have an appreciation of the operation of a Class IV laser and the handling of optical components.

    Full Text Available Digital projection technology allows for effective and entertaining spatial augmented reality applications. Leveraging the capabilities of reasonably accurate object tracking using commodity cameras and/or depth sensors to determine the 3D position and pose of objects in real time, it is possible to project dynamic graphical content on arbitrary surfaces, such as a person’s face. Coupling these capabilities with a simple drawing application, participants can have the experience of "painting" on someone’s face, or even on their own, by observing the projection in a mirror. Similarly, integrating 2D rigid-body, fluid and gravity simulation, one may interact with virtual objects projected on their own face or body.

  4. The mathematics of various entertaining subjects

    CERN Document Server

    Rosenhouse, Jason

    Volume 1 : The history of mathematics is filled with major breakthroughs resulting from solutions to recreational problems. Problems of interest to gamblers led to the modern theory of probability, for example, and surreal numbers were inspired by the game of Go. Yet even with such groundbreaking findings and a wealth of popular-level books exploring puzzles and brainteasers, research in recreational mathematics has often been neglected. The Mathematics of Various Entertaining Subjects brings together authors from a variety of specialties to present fascinating problems and solutions in recreational mathematics. Contributors to the book show how sophisticated mathematics can help construct mazes that look like famous people, how the analysis of crossword puzzles has much in common with understanding epidemics, and how the theory of electrical circuits is useful in understanding the classic Towers of Hanoi puzzle. The card game SET is related to the theory of error-correcting codes, and simple tic-tac-toe tak...

    Entertainment venues in China are associated with risky sexual behavior. Most previous studies related to entertainment venues in China have focused on sex workers and commercial sex, but this study addressed sexual health in a sample of the general urban population. A randomly selected sample of market vendors (n = 4,510) from an eastern city was recruited and assessed to examine relationships between entertainment venue visits and sexual risk. Both behavioral (self-reports of unprotected sex) and biomedical (STD test results) measures were used. About 18% of the sample (26.8% of men and 9% of women) reported visiting entertainment venues in the past 30 days. Those who visited entertainment venues were more likely to be male, younger, single, with higher education, and to have more discretionary income. For both men and women, visiting entertainment venues was a significant predictor for unprotected sex and STD infection. Gender differences were observed in predicting unprotected sex and STD infections. Entertainment venues could be potential sites for place-based intervention programs and outreach for the general population.

  12. Promoting Occupational Safety and Health for Cambodian Entertainment Sector Workers.

    2016-08-01

    Cambodia has developed booming textile, garment, tourism, and entertainment service industries since the mid-1990s. The 2007 global financial crisis pushed many garment workers, who lost their jobs, into the entertainment sector. Entertainment workers are typically engaged informally by their employers and are subjected to long working hours, sexual harassment, and violence. Many who sell beverages are forced into excessive alcohol consumption as part of their work. Many are also expected by their employers and clients to provide sexual services. To address unsafe and unhealthy working conditions for these workers, an innovative occupational safety and health regulation was adopted in 2014. This first-of-its-kind occupational safety and health regulation was developed jointly by the Cambodian Ministry of Labour and Vocational Training and employers' and workers' organizations in the entertainment sector. The implementation of this regulation can also be a viable contribution of occupational safety and health to HIV interventions for these workers. © The Author(s) 2016.

    Full Text Available The article discloses the cultural and social conditions of the entertainment phenomenon in Ancient Greece and Rome and the attitude of the authorities to it. The appearance of entertainment is closely related to the worship of cult of Gods. It is shown that the Romans being more materialistic and pragmatic paid less attention to spiritual entertainment than Greeks who fostered dramatic performances. Greek rulers and noblemen saw relaxational and educational function of the entertainment and also considered it as reducing tension and promoting solidarity. However, they did not intrude into its practical organization and had only a monitoring position, whereas the Romans were more interested in daily life and its bodily pleasures. Accordingly in recreational activities – games there dominated the spirit of competition, especially the gladiators games, which were bloody and cruel, but heated passions of spectators whose majority was comprised of plebs. There is shown that the authorities considered the entertainment as an effective tool to reach political aims, especially for gaining the support of commons in various elections, so they financed gladiators’ performances generously.This tradition is still topical in the flow of years. These days it has become the constituent part of the political marketing.

    The development of wireless biological electronic sensors could open up significant advances for both fundamental studies and practical applications in a variety of areas, including medical diagnosis, environmental monitoring, and defense applications. One of the major challenges in the development of wireless bioelectronic sensors is the successful integration of biosensing units and wireless signal transducers. In recent years, there are a few types of wireless communication systems that have been integrated with biosensing systems to construct wireless bioelectronic sensors. To successfully construct wireless biological electronic sensors, there are several interesting questions: What types of biosensing transducers can be used in wireless bioelectronic sensors? What types of wireless systems can be integrated with biosensing transducers to construct wireless bioelectronic sensors? How are the electrical sensing signals generated and transmitted? This review will highlight the early attempts to address these questions in the development of wireless biological electronic sensors.

    2007-01-01

    Researchers and practitioners who have sought to understand public reluctance to donating organs in spite of favorable attitudes toward organ donation have long thought that belief in myths about donation contribute to the problem. How these myths emerged and more important, why they have persisted in spite of national education campaigns is not clear. In the absence of direct personal experience with organ donation or transplantation, we believe that most people receive their information about donation through the media. In this study, we identify all entertainment television shows with organ donation storylines or subplots broadcast on ABC, NBC, CBS, and FOX from 2004-2005. Frame analysis reveals 2 competing metaframes: the moral corruption of the powerful and organ donors are good people. In addition to the metaframes, 4 secondary frames, and 6 tertiary frames are identified. Organ donation is framed in mostly negative terms, with a few notable exceptions. Recommendations for how to address negative framing of organ donation in the media are offered.

    This paper presents an overview of state-of-the-art architectures for integrating wireless sensor and actuators networks into the Future Internet. Furthermore, we will address advantages and disadvantages of the different architectures. With respect to these criteria, we develop a new architecture overcoming these weaknesses. Our system, called Smart Home Context Management System, will be used for intelligent home utilities, appliances, and electronics and includes physical, logical as well as network context sources within one concept. It considers important aspects and requirements of modern context management systems for smart X applications: plug and play as well as plug and trust capabilities, scalability, extensibility, security, and adaptability. As such, it is able to control roller blinds, heating systems as well as learn, for example, the user's taste w.r.t. to home entertainment (music, videos, etc.). Moreover, Smart Grid applications and Ambient Assisted Living (AAL) functions are applicable. With respect to AAL, we included an Emergency Handling function. It assures that emergency calls (police, ambulance or fire department) are processed appropriately. Our concept is based on a centralized Context Broker architecture, enhanced by a distributed Context Broker system. The goal of this concept is to develop a simple, low-priced, multi-functional, and save architecture affordable for everybody. Individual components of the architecture are well tested. Implementation and testing of the architecture as a whole is in progress.

    Full Text Available The first broadcast of a World Cup footballon television, to Brazil was in 1970, via Embratel. Before that, the people followed the games of the Brazilian team on the radio. Gradually, the owners of television networks realized that football could generate good financial results, with the exposing of advertisements during the broadcasts, similar to what was already done on the radio. Thus, the television, focused on the growth of audience and number of advertisers, covered football with a language of entertainment. The narration of the matches, in which the figure of the narrator is more like that of an entertainer, and improvement of the transmission technologies that improve the image quality every day, take away from football the characteristic of being just a sport to occupy the place of an entertainment. In this context, the sport becomes an article of purchase and sale. The purpose of this study is to demonstrate how this entertainment language was made up on Brazilian television, based on the broadcast sports, especially football, and like the television, which represented a technological leapin the country over the radio, assumed of the sport, country’s most popular as a commodity, interfering with the dynamics of Brazilian society. Finally, an attempt to understand how the researches that allow a technological development change behaviors and vice versa, that is, how the demands of society lead to a race to develop new technologies.

  4. A Wireless Sensor Enabled by Wireless Power

    Lee, Da-Sheng; Liu, Yu-Hong; Lin, Chii-Ruey

    2012-01-01

    Through harvesting energy by wireless charging and delivering data by wireless communication, this study proposes the concept of a wireless sensor enabled by wireless power (WPWS) and reports the fabrication of a prototype for functional tests. One WPWS node consists of wireless power module and sensor module with different chip-type sensors. Its main feature is the dual antenna structure. Following RFID system architecture, a power harvesting antenna was designed to gather power from a standard reader working in the 915 MHz band. Referring to the Modbus protocol, the other wireless communication antenna was integrated on a node to send sensor data in parallel. The dual antenna structure integrates both the advantages of an RFID system and a wireless sensor. Using a standard UHF RFID reader, WPWS can be enabled in a distributed area with a diameter up to 4 m. Working status is similar to that of a passive tag, except that a tag can only be queried statically, while the WPWS can send dynamic data from the sensors. The function is the same as a wireless sensor node. Different WPWSs equipped with temperature and humidity, optical and airflow velocity sensors are tested in this study. All sensors can send back detection data within 8 s. The accuracy is within 8% deviation compared with laboratory equipment. A wireless sensor network enabled by wireless power should be a totally wireless sensor network using WPWS. However, distributed WPWSs only can form a star topology, the simplest topology for constructing a sensor network. Because of shielding effects, it is difficult to apply other complex topologies. Despite this limitation, WPWS still can be used to extend sensor network applications in hazardous environments. Further research is needed to improve WPWS to realize a totally wireless sensor network. PMID:23443370

    The classic movie Metropolis (1926), which is nowadays considered a cinema milestone, has shown the possibility to build robots called androids that are science and fiction run together to realize a dream: the human-like robot. In that movie, Dr. Rotwang transforms a simple and cold calculating robot into the body of a beautiful woman. Robots have often been depicted as metal creatures with cold steel bodies, but there is no reason why metals should be the only kind of material for construction of robots. The authors examined the issues related to applying electroactive polymers materials (EAP) to the entertainment industry. EAP are offering attractive characteristics with the potential to produce more realistic models of living creatures at significantly lower cost. This paper seeks to elucidate how EAP might infiltrate and ultimately revolutionize entertainment, showing some applicative examples.

    Science.gov (United States)

    Shields, D.; Carol, J.; Balbach, E.; McGee, S.

    1999-01-01

    OBJECTIVE—To determine how people in the California-based entertainment industry think about the portrayal of tobacco use in movies and on television. Specifically, to explore who decides when to include tobacco in a project; how that decision is made; what issues are considered; what messages are intended; whether and how the issue of secondhand smoke is considered; and what advocacy methods might be useful in influencing future decisions about tobacco portrayal.
DESIGN—Qualitative in-depth interviews of entertainment industry personnel,with a semi-structured interview protocol to guide the interview.
SUBJECTS—54 subjects drawn from a convenience sample of writers, actors, directors, producers, studio executives, and others involved in the film industry.
RESULTS—Hollywood is heterogeneous with varying perspectives on rates of tobacco use portrayal; intentionality of the decision to use and the necessity to portray tobacco use; and its degree of acceptance of responsibility for influencing societal smoking. Tobacco depiction may originate with the writer, actor, or director and is included most frequently to elucidate character or portray reality. On-camera smoking is influenced by actors' off-camera tobacco use.
CONCLUSIONS—The research presented can help advocates better understand the norms and values of those working within the entertainment industry and thereby assist them in creating more effective change strategies.

    Electronic wireless sensors could cut medical costs by enabling physicians to remotely monitor vital signs such as blood pressure, blood glucose, and blood oxygenation while patients remain at home. According to the IDC report "Worldwide Bluetooth Semiconductor 2008-2012 Forecast," published November 2008, a forthcoming radio frequency communication ("wireless connectivity") standard, Bluetooth low energy, will link wireless sensors via radio signals to the 70% of cell phones and computers likely to be fitted with the next generation of Bluetooth wireless technology, leveraging a ready-built infrastructure for data transmission. Analysis of trends indicated by this data can help physicians better manage diseases such as diabetes. The technology also addresses the concerns of cost, compatibility, and interoperability that have previously stalled widespread adoption of wireless technology in medical applications.

  20. "Entertainment-education:" an idea whose time has come.

    Piotrow, P T

    1994-03-01

    The "enter-educate" technique, which presents educational messages in the guise of entertainment, is being used effectively all over the world. Soap operas depict the struggles of a single mother or of a father who has infected his family with AIDS, songs remind listeners that contraception gives them choices, and animated videos breathe new life into sex education. The Johns Hopkins University has supported approximately 36 television series and specials, 9 radio dramas, 3 songs, and 9 music videos. Other organizations are expanding their work in this field. Surveys before and after exposure to enter-educate productions and clinic records can be used to measure changes in attitudes and behavior attributable to the productions. Evaluations of projects have shown that the audience pays attention and then moves from understanding to agreement to action (such as talking to their spouse or family, going to a clinic, using family planning, or practicing safer sex). The theoretical basis for the enter-educate approach can be traced to Aristotle who discussed the capacity for drama to convey moral teaching. More recently, Albert Bandura developed a theory of social learning which states that people learn by observing and adapting the behavior of others to their own lives. Miguel Sabido, a Mexican producer, applied Bandura's theory to develop the first enter-educate soap operas. The enter-educate approach is pervasive (through rapidly spreading mass media), popular (people seek entertainment), personal (depicting the private lives of the characters), passionate (invoking intense emotions), persuasive (through audience identification with characters), practical (since the talent and delivery infrastructure already exists), and profitable (entertainment pays its way, can generate profits and promote careers, and is cost-effective).

    Spike is the only television network in North America “for men.” Its motto, “Get more action,” is suggestive of pursuits of various forms of violence. We conceptualize Spike not as trivial entertainment, but rather as a form of pop culture that erodes the gains of feminists who have challenged the prevalence of normalized hegemonic masculinity (HM). Our paper highlights themes of Spike content, and connects those themes to the literature on HM. Moreover, we validate the identities and lives ...

    Malatesta, L.; Raouzaiou, A.; Pearce, L.; Karpouzis, K.

    The current work presents the affective interface adaptations in the Musickiosk application. Adaptive interaction poses several open questions since there is no unique way of mapping affective factors of user behaviour to the output of the system. Musickiosk uses a non-contact interface and implicit interaction through emotional affect rather than explicit interaction where a gesture, sound or other input directly maps to an output behaviour - as in traditional entertainment applications. PAD model is used for characterizing the different affective states and emotions.

    Wireless computer networks are increasing exponentially around the world. They are being implemented in both the unlicensed radio frequency (RF) spectrum (IEEE 802.11a/b/g) and the licensed spectrum (e.g., Firetide [1] and Motorola Canopy [2]). Wireless networks operating in the unlicensed spectrum are by far the most popular wireless computer networks in existence. The open (i.e., proprietary) nature of the IEEE 802.11 protocols and the availability of ''free'' RF spectrum have encouraged many producers of enterprise and common off-the-shelf (COTS) computer networking equipment to jump into the wireless arena. Competition between these companies has driven down the price of 802.11 wireless networking equipment and has improved user experiences with such equipment. The end result has been an increased adoption of the equipment by businesses and consumers, the establishment of the Wi-Fi Alliance [3], and widespread use of the Alliance's ''Wi-Fi'' moniker to describe these networks. Consumers use 802.11 equipment at home to reduce the burden of running wires in existing construction, facilitate the sharing of broadband Internet services with roommates or neighbors, and increase their range of ''connectedness''. Private businesses and government entities (at all levels) are deploying wireless networks to reduce wiring costs, increase employee mobility, enable non-employees to access the Internet, and create an added revenue stream to their existing business models (coffee houses, airports, hotels, etc.). Municipalities (Philadelphia; San Francisco; Grand Haven, MI) are deploying wireless networks so they can bring broadband Internet access to places lacking such access; offer limited-speed broadband access to impoverished communities; offer broadband in places, such as marinas and state parks, that are passed over by traditional broadband providers; and provide themselves with higher quality, more

    People spend considerable amounts of time and money listening to music, watching TV and movies, and reading books and magazines, yet almost no attention in psychology has been devoted to understanding individual differences in preferences for such entertainment. The present research was designed to examine the structure and correlates of entertainment genre preferences. Analyses of the genre preferences of more than 3,000 individuals revealed a remarkably clear factor structure. Using multiple samples, methods, and geographic regions, data converged to reveal five entertainment-preference dimensions: Communal, Aesthetic, Dark, Thrilling, and Cerebral. Preferences for these entertainment dimensions were uniquely related to demographics and personality traits. Results also indicated that personality accounted for significant proportions of variance in entertainment preferences over and above demographics. The results provide a foundation for developing and testing hypotheses about the psychology of entertainment preferences. © 2011 The Authors. Journal of Personality © 2011, Wiley Periodicals, Inc.

  9. A Robust Camera-Based Interface for Mobile Entertainment

    2016-02-01

    Full Text Available Camera-based interfaces in mobile devices are starting to be used in games and apps, but few works have evaluated them in terms of usability or user perception. Due to the changing nature of mobile contexts, this evaluation requires extensive studies to consider the full spectrum of potential users and contexts. However, previous works usually evaluate these interfaces in controlled environments such as laboratory conditions, therefore, the findings cannot be generalized to real users and real contexts. In this work, we present a robust camera-based interface for mobile entertainment. The interface detects and tracks the user’s head by processing the frames provided by the mobile device’s front camera, and its position is then used to interact with the mobile apps. First, we evaluate the interface as a pointing device to study its accuracy, and different factors to configure such as the gain or the device’s orientation, as well as the optimal target size for the interface. Second, we present an in the wild study to evaluate the usage and the user’s perception when playing a game controlled by head motion. Finally, the game is published in an application store to make it available to a large number of potential users and contexts and we register usage data. Results show the feasibility of using this robust camera-based interface for mobile entertainment in different contexts and by different people.

    To test the entertainment media as an effective method for distributing social messages, a project was developed to promote responsible sexual behavior of young people in the Philippines. Music videos were used to sell the message of responsible sexual behavior and to encourage counseling for discussing and solving their problems. In surveys 4 months after the project began, 90% of the young people heard the message and after 6 months, 82% responded to aided recall. There are also indications that about 50% of the people that heard the message talked about it with their friends and peers. Over 56% stated that it had an impact on them and 7/10 of these asked for more information on boy-girl relationships. The information sought was in relation to choice, maintaining the relationship, self-control, marriage preparation, and education priority. After 7 months, 9/10 surveyed were aware of the telephone counseling service offered. There were over 1300 calls handled each month; most of the callers were single girls between 15-24 years of age, and needed information on boy-girl, parent-child, and peer relationships. In addition, sexual behavior, self esteem, and marriage questions were asked. The majority (82%) of those surveyed believed that a boy-girl relationship needs love, sharing, respect, commitment and open communication. Over half believed sexual relations should begin after marriage and 47% believed in sexual relations when they were mature enough. This program demonstrated that media entertainment education for social development is promising.

  1. Wireless sensor networks for monitoring physiological signals of multiple patients.

    Dilmaghani, R S; Bobarshad, H; Ghavami, M; Choobkar, S; Wolfe, C

    2011-08-01

    This paper presents the design of a novel wireless sensor network structure to monitor patients with chronic diseases in their own homes through a remote monitoring system of physiological signals. Currently, most of the monitoring systems send patients' data to a hospital with the aid of personal computers (PC) located in the patients' home. Here, we present a new design which eliminates the need for a PC. The proposed remote monitoring system is a wireless sensor network with the nodes of the network installed in the patients' homes. These nodes are then connected to a central node located at a hospital through an Internet connection. The nodes of the proposed wireless sensor network are created by using a combination of ECG sensors, MSP430 microcontrollers, a CC2500 low-power wireless radio, and a network protocol called the SimpliciTI protocol. ECG signals are first sampled by a small portable device which each patient carries. The captured signals are then wirelessly transmitted to an access point located within the patients' home. This connectivity is based on wireless data transmission at 2.4-GHz frequency. The access point is also a small box attached to the Internet through a home asynchronous digital subscriber line router. Afterwards, the data are sent to the hospital via the Internet in real time for analysis and/or storage. The benefits of this remote monitoring are wide ranging: the patients can continue their normal lives, they do not need a PC all of the time, their risk of infection is reduced, costs significantly decrease for the hospital, and clinicians can check data in a short time.

  14. Wireless remote monitoring system for sleep apnea

    Oh, Sechang; Kwon, Hyeokjun; Varadan, Vijay K.

    2011-04-01

    Sleep plays the important role of rejuvenating the body, especially the central nervous system. However, more than thirty million people suffer from sleep disorders and sleep deprivation. That can cause serious health consequences by increasing the risk of hypertension, diabetes, heart attack and so on. Apart from the physical health risk, sleep disorders can lead to social problems when sleep disorders are not diagnosed and treated. Currently, sleep disorders are diagnosed through sleep study in a sleep laboratory overnight. This involves large expenses in addition to the inconvenience of overnight hospitalization and disruption of daily life activities. Although some systems provide home based diagnosis, most of systems record the sleep data in a memory card, the patient has to face the inconvenience of sending the memory card to a doctor for diagnosis. To solve the problem, we propose a wireless sensor system for sleep apnea, which enables remote monitoring while the patient is at home. The system has 5 channels to measure ECG, Nasal airflow, body position, abdominal/chest efforts and oxygen saturation. A wireless transmitter unit transmits signals with Zigbee and a receiver unit which has two RF modules, Zigbee and Wi-Fi, receives signals from the transmitter unit and retransmits signals to the remote monitoring system with Zigbee and Wi-Fi, respectively. By using both Zigbee and Wi-Fi, the wireless sensor system can achieve a low power consumption and wide range coverage. The system's features are presented, as well as continuous monitoring results of vital signals.

    Objective Throughout the past several years, there have been a number of entertainment celebrity suicides in South Korea. The aim of this study was to investigate the clustering of suicides following celebrities' suicides in South Korea from 2005 to 2008, particularly according to certain characteristics. Methods Seven celebrity suicides were examined and defined using the Korean Integrated Newspaper Database System (KINDS) and from these, we considered four affected periods occurring 28 days after each celebrity's suicide. A Poisson time-series autoregression model was used to estimate the relative risk of the total suicide number for each affected period from 2005 to 2008. Logistic regression analysis was performed to investigate whether there were specific increases in the numbers of suicides in subgroups matching each celebrity. Results There were significant increases in the risk of suicide during the affected periods. Remarkable increases were found in the subgroups matching each celebrity, especially in the group in which all factors (sex, age, and method) were similar. Conclusion This study provides confirmation that a significant copycat effect was induced by these celebrities' suicides, especially among people who identified more with the celebrities. This implies that countermeasures for upright media coverage of celebrity suicides should be discussed and practiced properly in South Korea. PMID:26766949

  6. Entertaining Democracy in the Era of Neo-Liberalism

    Directory of Open Access Journals (Sweden)

    James Curran

    2016-08-01

    Full Text Available James Curran’s article “Entertaining democracy in the Era of Neo-liberalism” is an essay written from the 13th SBPJor Conference Meeting in Campo Grande in 2015; a conference in which he was the opening speaker. The article was approved for publication in the BJR at the end of 2015, but we have decided to publish it in a special edition of Journalism and Democracy as it deals precisely with this issue. Curran begins the article by questioning the current state of democracy as it pertains to the decline of the nation state and the emergence of transnational institutions of deliberation which he calls “multilevel governance” but “is not matched by the development of a multilevel sense of citizenship”. As almost a prelude to the Brexit, Curran draws attention to the fact that the English do not consider themselves European despite being a part of the European Union. He tied this nationalist ideal not only to the British, but to other country populations in general. In a world dominated by transnational corporations and the presence and constancy of national media “supporting a national identity” he predicted that “Attempts at new institutional building are out of step with media development”. His analysis highlights several problems that are weakening modern democracy like “the increasing centralization of power by political leaders” and the “increasingly unrepresentative nature of the political class  rendering them in some countries almost a ‘separate caste’”. Reading Curran’s text allows us to reflect on the situation in Brazil. At first, it is pessimistic and places meanings that we have lobbied for outside of our borders: “Governments are less able to govern; political power is becoming more centralized; and the unelected influence of big business is becoming greater”. The media also has a hand in contributing towards a “growing sense of disconnection from politics”, making reference to politics as

    1992-01-01

    Health communicators use entertainment and mass media to prevent HIV transmission. Population Services International operates an AIDS Mass Media Project as an adjunct to its Condom Social Marketing Project. It collaborates with the Government of Zaire's National AIDS Program. Its 1st target is urban youth because most AIDS cases in Zaire were infected as teenagers, urban youth have access to television (TV), and they take part in high risk sexual behavior. The project uses various AIDS songs to reach this group. A 6-month posttest shows that the 1st song was so effective that 65% heard it and that 93% of them recalled the major AIDS messages and 85% said that they changed their behavior. The project distributes a video of the 1990 World AIDS Day concert. Research in Zaire and other African countries shows that the threat AIDS poses to children's health strongly motivates parents' behavior. Thus the 2nd target is the 20-30 year old group--young and prospective parents. The project boasts a 4-part TV series about a groom who does not reveal his AIDS status to his young bride until after their wedding night. 2 scenes stress the benefits of condoms. After its 1st airing, 66% of the 20-30 year old group in Kinshasa watched all 4 parts of the series. Of these, about 75% said they would change their behavior. Most people in Zaire change behavior by using condoms. Indeed, during the mass media campaign, condom sales grew 1000% which saved almost 7200 lives. The project also features comic strips informing working men and women and teenagers about AIDS and distributes an inexpensive notebook listening AIDS facts and myths for school children. The project uses regional radio stations to broadcast 28 AIDS feature programs, 22 radio spots, 8 AIDS radio dramas, and 2 songs to high priority rural areas. These AIDS radio efforts have indeed influenced AIDS knowledge and attitudes.

    2016-02-01

    Full Text Available The growing demand of bandwidth in this modern internet age has been testing the existing telecommunication infrastructures around the world. With broadband speeds moving towards the region of Gbps and Tbps, many researches have begun on the development of using optical wireless technology as feasible and future methods to the current wireless technology. Unlike the existing radio frequency wireless applications, optical wireless uses electromagnetic spectrums that are unlicensed and free. With that, this project aim to understand and gain better understanding of optical wireless communication system by building an experimental and simulated model. The quality of service and system performance will be investigated and reviewed. This project employs laser diode as the propagation medium and successfully transferred audio signals as far as 15 meters. On its quality of service, results of the project model reveal that the bit error rate increases, signal-to-noise ratio and quality factor decreases as the link distance between the transmitter and receiver increases. OptiSystem was used to build the simulated model and MATLAB was used to assist signal-to-noise ratio calculations. By comparing the simulated and experimental receiver’s power output, the experimental model’s efficiency is at 66.3%. Other than the system’s performance, challenges and factors affecting the system have been investigated and discussed. Such challenges include beam divergence, misalignment and particle absorption.

    This brief focuses on radio resource allocation in a heterogeneous wireless medium. It presents radio resource allocation algorithms with decentralized implementation, which support both single-network and multi-homing services. The brief provides a set of cooperative networking algorithms, which rely on the concepts of short-term call traffic load prediction, network cooperation, convex optimization, and decomposition theory. In the proposed solutions, mobile terminals play an active role in the resource allocation operation, instead of their traditional role as passive service recipients in the networking environment.

    Broadband wireless networks based on a number of new frequency windows at higher microwave and millimeter-wave frequencies have been actively pursued to provide ultra-high bandwidth services over a wireless networks. These networks will have a large number of antenna base-stations with high throughput. Significant reductions in antenna base-station complexity can be achieved if most of the signal routing and switching functions centralized at a central office in the network. In such a network, fiber feed networks can be effectively deployed to provide high bandwidth interconnections between multiple antenna base-stations and the central office. With wavelength division multiplexing, efficient optical fiber feed network architectures could be realised to provide interconnection to a large number of antenna base-stations. In this paper, we present an over view of our recent research into system technologies for fiber wireless networks.

    Poor, H. Vincent; Schaefer, Rafael F.

    2017-01-01

    Security in wireless networks has traditionally been considered to be an issue to be addressed separately from the physical radio transmission aspects of wireless systems. However, with the emergence of new networking architectures that are not amenable to traditional methods of secure communication such as data encryption, there has been an increase in interest in the potential of the physical properties of the radio channel itself to provide communications security. Information theory provides a natural framework for the study of this issue, and there has been considerable recent research devoted to using this framework to develop a greater understanding of the fundamental ability of the so-called physical layer to provide security in wireless networks. Moreover, this approach is also suggestive in many cases of coding techniques that can approach fundamental limits in practice and of techniques for other security tasks such as authentication. This paper provides an overview of these developments.

  2. Terabit Wireless Communication Challenges

    Science.gov (United States)

    Hwu, Shian U.

    2012-01-01

    This presentation briefly discusses a research effort on Terabit Wireless communication systems for possible space applications. Recently, terahertz (THz) technology (300-3000 GHz frequency) has attracted a great deal of interest from academia and industry. This is due to a number of interesting features of THz waves, including the nearly unlimited bandwidths available, and the non-ionizing radiation nature which does not damage human tissues and DNA with minimum health threat. Also, as millimeter-wave communication systems mature, the focus of research is, naturally, moving to the THz range. Many scientists regard THz as the last great frontier of the electromagnetic spectrum, but finding new applications outside the traditional niches of radio astronomy, Earth and planetary remote sensing, and molecular spectroscopy particularly in biomedical imaging and wireless communications has been relatively slow. Radiologists find this area of study so attractive because t-rays are non-ionizing, which suggests no harm is done to tissue or DNA. They also offer the possibility of performing spectroscopic measurements over a very wide frequency range, and can even capture signatures from liquids and solids. According to Shannon theory, the broad bandwidth of the THz frequency bands can be used for terabit-per-second (Tb/s) wireless communication systems. This enables several new applications, such as cell phones with 360 degrees autostereoscopic displays, optic-fiber replacement, and wireless Tb/s file transferring. Although THz technology could satisfy the demand for an extremely high data rate, a number of technical challenges need to be overcome before its development. This presentation provides an overview the state-of-the- art in THz wireless communication and the technical challenges for an emerging application in Terabit wireless systems. The main issue for THz wave propagation is the high atmospheric attenuation, which is dominated by water vapor absorption in the THz

    2015-11-01

    Students at the University of Arizona have a relatively rare opportunity to learn in a state-of-the-art planetarium. Originally opened as a campus planetarium in 1975, the Flandrau Science Center recently expanded into the digital realm. In 2014 Flandrau’s antique Minolta star projector was joined by a full-dome 4K digital projection system powered by a high performance computer cluster. Currently three science courses are taught in the planetarium for non-science majors — stellar astronomy, astrobiology, and planetary science (taught by SJK).The new digital system allows us to take our classes off the surface of Earth on a journey into the cosmos. Databases from dozens of spacecraft missions and deep-space telescopic surveys are tapped by the software to generate a realistic immersive 3D perspective of the universe, from local planets, satellites and rings to distant stars and galaxies all the way out to the limit of the visible universe. Simple clicks of a mouse allow us to change the orientation, trajectory, and speed of the virtual spacecraft, giving our students diverse views of different phenomena.The challenge with this system is harnessing the entertainment aspect for educational purposes. The visualization capabilities allow us to artificially enhance certain features and time scales. For example, the sizes of Earth and the moon can be enlarged on-the-fly to help demonstrate phases and eclipses. Polar axes and latitude lines can be added to Earth as it orbits the sun to help convey the reasons for seasons. Orbital paths can be highlighted to allow students to more accurately comprehend the population of near-Earth asteroids.These new immersive computer-generated visualization techniques have the potential to enhance comprehension in science education, especially for concepts involving 3D spatial and temporal relationships. Whether or not this potential is being realized will require studies to gauge student learning and retention beyond the short

  4. Energy Survival: entertainment as a resource for local energy actions

    Energy Technology Data Exchange (ETDEWEB)

    Elburg, Henk van; Moosdijk, Catelijne van de [SenterNovem (Netherlands)

    2007-07-01

    In 2005, SenterNovem, the Dutch Broadcasting Corporation, a publishing company and a consortium of local authorities launched 'Energy Survival'; a renewing energy marketing strategy for children to create a demand for local energy actions. New elements are powerful branding and the use of cross media techniques through national TV, internet, local events and primary education. Through entertainment, Energy Survival influences children's attitude towards energy consumption and its convincing relation with the environment. It aims at qualifying children to become 'energy ambassadors' in their own local environment: family, school and neighbourhood. Energy Survival has become a well tested energy game-concept for children in whom public and private partners cooperate under one brand name and with a clear division of roles and interests. However, the backbone of the concept is the local approach: local actions in municipalities and in primary schools, supported by television and internet where children learn to deal with the upcoming energy challenges of the planet they will inherit. By providing an internet-based teaching method, especially primary schools will be an effective multiplier to reach children. Broadcasting the energy game on national TV on the one hand, and local events and preliminaries on the other hand, ensure opportunities for widespread 'duplication' of the concept, adapted to local policy priorities regarding sustainable energy because each municipality is permitted to choose its own themes. Despite the fact that the project is still young and that the partners consider it as a 'long term-investment', the first independent monitoring results indicate that Energy Survival so far is quite successful. Ratings of the first TV-series show a national market share of 20 % in the age group 6-12 years and significantly more interaction between children and their parents on energy related issues.

    Entertainment education and the promotora model are 2 evidence-based health communication strategies. This study examined their combined effect on promoting healthy eating among mothers in a family-based intervention. Participants were 361 Mexican-origin families living in Imperial County, California, who were randomly assigned to an intervention or delayed treatment condition. The intervention involved promotoras (community health workers) who delivered 11 home visits and 4 telephone calls. Home visits included a 12-minute episode of a 9-part situation comedy depicting a family struggling with making healthy eating choices; an accompanying family workbook was reviewed to build skills and left with the family. Baseline and immediate postintervention data were collected from the mothers, including the primary outcome of daily servings of fruits and vegetables. Other dietary and psychosocial factors related to healthy eating were examined. At postintervention, mothers in the intervention reported increases in daily vegetable servings (p ≤ .05); however, no changes were observed in fruit consumption. Improvements were observed in behavioral strategies to increase fiber (p ≤ .001) and to decrease fat intake (p ≤ .001), unhealthy eating behaviors (p ≤ .001), and individual (p ≤ .05) and family-related (p ≤ .01) perceived barriers to healthy eating. Entertainment education and promotoras engaged families and improved mothers' diets. Further research should examine the dose needed for greater changes.

    International Nuclear Information System (INIS)

    Nasri, M.; Helali, A.; Sghaier, H.; Maaref, H.

    2011-01-01

    The emerging technology during the last years allowed the development of new sensors equipped with wireless communication which can be organized into a cooperative autonomous network. Some application areas for wireless sensor networks (WSNs) are home automations, health care services, military domain, and environment monitoring. The required constraints are limited capacity of processing, limited storage capability, and especially these nodes are limited in energy. In addition, such networks are tiny battery powered which their lifetime is very limited. During image processing and transmission to the destination, the lifetime of sensor network is decreased quickly due to battery and processing power constraints. Therefore, digital image transmissions are a significant challenge for image sensor based Wireless Sensor Networks (WSNs). Based on a wavelet image compression, we propose a novel, robust and energy-efficient scheme, called Priority Image Transmission (PIT) in WSN by providing various priority levels during image transmissions. Different priorities in the compressed image are considered. The information for the significant wavelet coeffcients are transmitted with higher quality assurance, whereas relatively less important coefficients are transmitted with lower overhead. Simulation results show that the proposed scheme prolongs the system lifetime and achieves higher energy efficiency in WSN with an acceptable compromise on the image quality.

    Wireless communication is witnessing tremendous growth with proliferation of different standards covering wide, local and personal area networks (WAN, LAN and PAN). The trends call for designs that allow 1) smooth migration to future generations of wireless standards with higher data rates for multimedia applications, 2) convergence of wireless services allowing access to different standards from the same wireless device, 3) inter-continental roaming. This requires designs that work across multiple wireless standards, can easily be reused, achieve maximum hardware share at a minimum power consumption levels particularly for mobile battery-operated devices.

    During the last few years, wireless networks have been increasingly used both inside hospitals and in patients' homes to transmit medical information. In general, wireless networks suffer from decreased security. However, digital watermarking can be used to secure medical information. In this study, we focused on combining wireless transmission and digital watermarking technologies to better secure the transmission of medical images within and outside the hospital. We utilized an integrated system comprising the wireless network and the digital watermarking module to conduct a series of tests. The test results were evaluated by medical consultants. They concluded that the images suffered no visible quality degradation and maintained their diagnostic integrity. The proposed integrated system presented reasonable stability, and its performance was comparable to that of a fixed network. This system can enhance security during the transmission of medical images through a wireless channel.

    Full Text Available BACKGROUND: Noise-induced hearing loss (NIHL is a major concern in the non-manufacturing industries. This study aimed to investigate the occupational noise exposure and the NIHL among Chinese restaurant workers and entertainment employees working in the service industry in Hong Kong. METHODS: This cross-sectional survey involved a total of 1,670 participants. Among them, 937 were randomly selected from the workers of Chinese restaurants and 733 were selected from workers in three entertainment sectors: radio and television stations; cultural performance halls or auditoria of the Leisure and Cultural Services Department (LCSD; and karaoke bars. Noise exposure levels were measured in the sampled restaurants and entertainment sectors. Each participant received an audiometric screening test. Those who were found to have abnormalities were required to take another diagnostic test in the health center. The "Klockhoff digit" method was used to classify NIHL in the present study. RESULTS: The main source of noise inside restaurants was the stoves. The mean hearing thresholds showed a typical dip at 3 to 6 KHz and a substantial proportion (23.7% of the workers fulfilled the criteria for presumptive NIHL. For entertainment sectors, employees in radio and television stations generally had higher exposure levels than those in the halls or auditoria of the LCSD and karaoke bars. The mean hearing thresholds showed a typical dip at 6 KHz and a substantial proportion of the employees fulfilled the criteria for presumptive NIHL (38.6%, 95%CI: 35.1-42.1%. Being male, older, and having longer service and daily alcohol consumption were associated with noise-induced hearing impairment both in restaurant workers and entertainment employees. CONCLUSION: Excessive noise exposure is common in the Chinese restaurant and entertainment industries and a substantial proportion of restaurant workers and entertainment employees suffer from NIHL.

    Full Text Available This paper presents the design of a wireless remote control system based on the ZigBee communication protocol. Gathering data from sensors or performing control tasks through wireless communication is advantageous in situations in which the use of cables is impractical. An Atmega328 microcontroller (from slave device is used for gathering data from the sensors and transmitting it to a coordinator device with the help of the XBee modules. The ZigBee standard is suitable for low-cost, low-data-rate and low-power wireless networks implementations. The XBee-PRO module, designed to meet ZigBee standards, requires minimal power for reliable data exchange between devices over a distance of up to 1600m outdoors. A key component of the ZigBee protocol is the ability to support networking and this can be used in a wireless remote control system. This system may be employed e.g. to control temperature and humidity (SHT11 sensor and light intensity (TSL230 sensor levels inside a commercial greenhouse.

    Conventional thinking holds that underground- and underwater radio communication is not possible, except at very low frequencies employing very long antennas and high transmit power. However, researchers at The University of Iowa have demonstrated that using inexpensive, low-power radios, it is in fact possible to achieve reliable underground radio communication over distances of several meters. This allows for creating underground wireless sensor networks. A proof-of-concept network was established at The University of Iowa, where nodes that measure soil moisture content are buried over a 20×20 m area (up to 1 m deep). The nodes organize themselves into a wireless sensor network, reconfigure routes as radio link quality waxes and wanes, cooperate in routing data packets to a surface base station, and so on. In an agricultural research setting, an advantage of such buried wireless sensor networks is that, if nodes were buried deep enough, they may be left in place during agricultural field work. Power consumption is an important issue in wireless sensor networks. This is especially true in a buried network where battery replacement is a major undertaking. The focus of continuing research is developing methods of inductively recharging buried sensor batteries.

    Wireless is a powerful core technology enabling our global digital infrastructure. Wi-Fi networks are susceptible to attacks on Wired Equivalency Privacy, Wi-Fi Protected Access (WPA), and WPA2. These attack signatures can be profiled into a system that defends against such attacks on the basis of their inherent characteristics. Wi-Fi is the standard protocol for wireless networks used extensively in US critical infrastructures. Since the Wired Equivalency Privacy (WEP) security protocol was broken, the Wi-Fi Protected Access (WPA) protocol has been considered the secure alternative compatible with hardware developed for WEP. However, in November 2008, researchers developed an attack on WPA, allowing forgery of Address Resolution Protocol (ARP) packets. Subsequent enhancements have enabled ARP poisoning, cryptosystem denial of service, and man-in-the-middle attacks. Open source systems and methods (OSSM) have long been used to secure networks against such attacks. This article reviews OSSMs and the results of experimental attacks on WPA. These experiments re-created current attacks in a laboratory setting, recording both wired and wireless traffic. The article discusses methods of intrusion detection and prevention in the context of cyber physical protection of critical Internet infrastructure. The basis for this research is a specialized (and undoubtedly incomplete) taxonomy of Wi-Fi attacks and their adaptations to existing countermeasures and protocol revisions. Ultimately, this article aims to provide a clearer picture of how and why wireless protection protocols and encryption must achieve a more scientific basis for detecting and preventing such attacks.

  8. NASA Bluetooth Wireless Communications

    2007-01-01

    NASA has been interested in wireless communications for many years, especially when the crew size of the International Space Station (ISS) was reduced to two members. NASA began a study to find ways to improve crew efficiency to make sure the ISS could be maintained with limited crew capacity and still be a valuable research testbed in Low-Earth Orbit (LEO). Currently the ISS audio system requires astronauts to be tethered to the audio system, specifically a device called the Audio Terminal Unit (ATU). Wireless communications would remove the tether and allow astronauts to freely float from experiment to experiment without having to worry about moving and reconnecting the associated cabling or finding the space equivalent of an extension cord. A wireless communication system would also improve safety and reduce system susceptibility to Electromagnetic Interference (EMI). Safety would be improved because a crewmember could quickly escape a fire while maintaining communications with the ground and other crewmembers at any location. In addition, it would allow the crew to overcome the volume limitations of the ISS ATU. This is especially important to the Portable Breathing Apparatus (PBA). The next generation of space vehicles and habitats also demand wireless attention. Orion will carry up to six crewmembers in a relatively small cabin. Yet, wireless could become a driving factor to reduce launch weight and increase habitable volume. Six crewmembers, each tethered to a panel, could result in a wiring mess even in nominal operations. In addition to Orion, research is being conducted to determine if Bluetooth is appropriate for Lunar Habitat applications.

  9. Examining relations of entertainment with social interaction motives and team identification.

    2010-10-01

    The goal was to investigate a potential causal pattern between the motives of sport spectators and team identification by using a cross-lagged panel design. Questionnaires were completed by 229 participants at the beginning and end of one NCAA (National Collegiate Athletic Association) college football season for 4 mo. in the USA. The questionnaire included three items for each motive (Social Interaction and Entertainment), three items measuring team identification, and demographic items. The relation of Entertainment at Time 1 to team identification at Time 2 was larger than the relation of team identification at Time 1 to Entertainment at Time 2. This suggests that the motivation of Entertainment may lead to the formation of team identification more than team identification leads to Entertainment. However, the motive of Social Interaction did not show the same pattern. As results of this study suggested some spectator sport motives might lead to identification with a team, the hypothesis that all motives would be the basis of team identification might not be correct.

  10. Pro-socially shareable entertainment television programmes: a programming alternative in developing countries?

    Science.gov (United States)

    Singhal, A; Svenkerud, P J

    1994-12-01

    Over the period 1975-82, the Mexican television network created and aired seven entertainment soap operas promoting educational-development themes like adult literacy, smaller family size norms, and an higher social status for women. These emissions earned high ratings in Mexico and in other Latin American countries where they were subsequently broadcast. Evidence suggests that many of the social objectives of the soaps were met. In light of such success, the authors investigated the potential of pro-socially shareable entertainment television programs in developing countries. These programs use entertaining media formats to carry pro-social messages to a wide, yet culturally-proximate audience group. Entertainment television genres such as melodramatic soap operas offer certain advantages for carrying pro-socially shareable messages to audiences. The possibility of using other television genres and media channels, however, also needs to be seriously considered. Pro-socially shareable entertainment programs do have their limitations and problems, with a certain degree of message dilution invariably accompanying the quest for shareability. Targeting specific problems in specific audience groups is difficult and the identity of a relatively small homogeneous group can be threatened in a larger culturally proximate group. The value-laden nature of pro-social content can also be problematic.

    Full Text Available Topic: Using a qualitative methodology, this study attempts to provide a general framework of the functions of mobile communication, and to identify the specific preferences of mobile phone users regarding the commercial messages received on their personal devices. Research objectives: (1 To identify the specific characteristics of mobile communication as perceived by mobile users; (2 to define and analyze the functions of wireless communication as perceived by mobile phone users; and (3 to investigate users preference regarding the content of commercial wireless communication. Previous research: Bauer et al. (2002 identified time, location, information and personalization as relevant acceptance factors for mobile advertising. Barwise and Strong (2002 developed a conceptual model, arguing that social norms, user's motives, mode, time, location and personal characteristics will affect the processing of mobile information by consumers. Tsang et al. (2004 evidenced the influence of entertainment, informativeness and irritation, while Bauer et al. (2005 argued that consumer attitudes are influenced by perceived information, entertainment, and social utility. In a similar study, Xu and Gutierrez (2006 tested the effect of entertainment, irritation, informativeness, credibility and personalization on the attitudes of Chinese consumers. Research methodology: First, a series of academic and practical articles and reports have been accessed in order to assess the existing knowledge on this topic. Second, five focus groups have been organized with six mobile phone users, aged between 20 and 40 years old. Each focus group comprised an equal number of male and female participants. The focus groups lasted between 45 and 60 minutes and addressed three main issues: the specific characteristics of the mobile phones as a commercial communication media, the functions of mobile phone communication, and the specific preferences of mobile phones users regarding the

    This article presents an entertainment education strategy used to influence Hollywood prime-time and daytime television programs to add storylines on the importance of immunizations to their shows. Rather than giving information about immunizations to show producers, directors, actors, and writers, we furnished "log lines" and true stories about immunizations that could be used to inspire scripts that included immunization themes. By working through personal contacts within the entertainment television industry's closed system of networks, we were able to gain entree and some airtime for our campaign agenda. Embedded messages aired on eight popular shows in the 1996-1997 broadcast season, with five scheduled to air in the 1997-1998 season. These efforts were evaluated qualitatively, focusing on issues of personal networks, content of aired messages, and comparative costs for paid airtime. The strategy developed can be adapted for a range of entertainment education interventions.

    2013-01-01

    Following our article entitled “Jekyll or Hyde? Better browse securely” in the last issue of the Bulletin, some people wondered why the CERN wireless network is not encrypted…   There are many arguments why it is not. The simplest is usability: the communication and management of the corresponding access keys would be challenging given the sheer number of wireless devices the CERN network hosts. Keys would quickly become public, e.g. at conferences, and might be shared, written on whiteboards, etc. Then there are all the devices which cannot be easily configured to use encryption protocols - a fact which would create plenty of calls to the CERN Service Desk… But our main argument is that wireless encryption is DECEPTIVE. Wireless encryption is deceptive as it only protects the wireless network against unauthorised access (and the CERN network already has other means to protect against that). Wireless encryption however, does not really help you. You ...

    2006-01-01

    This study examines the relative contribution of exposure to entertainment and music magazines on binge drinking among a group of teenagers under the supervision of a juvenile court system in a medium-sized western United States community. Despite having a large proportion of adolescent readers, entertainment and music magazines typically include a substantial number of advertisements for alcoholic beverages in each issue. Data were collected via a self-report questionnaire administered to 342 juvenile offenders (ages 12-18 years). Three-quarters of our respondents reported they have used alcohol and about 37% indicated they were binge drinkers. As anticipated, binge drinkers were more frequent readers of entertainment and music magazines than non-binge drinkers. Binge drinkers also estimated that larger portions of their classmates used alcohol and would be more accepting of regular drinking than non-binge drinkers. Results of a multivariate logistic regression analysis to predict whether our subjects typically consumed five or more drinks during a drinking episode indicated that perceived ease of access, age, gender, the number of best friends who drink, parental drinking (inversely), and entertainment and music magazine reading frequency were significant predictors of binge drinking. We conclude that the predictive influence entertainment and music magazine reading frequency may actually reflect a selectivity bias among a segment of the youth sub-culture already inclined toward alcohol use and abuse. We recommend that entertainment and music magazine reading should be considered only within the constellation of other risk factors when assessing risk for potential alcohol abuse.

    2009-01-01

    This chapter examines the official 'entertainment', in all its forms, provided to inmates in Australian and New Zealand asylums--later mental hospitals--between c.1860 and c.1945. Visitors came into asylum grounds and patients were permitted periods of leave, all for the purposes of entertainment and recreation. Surviving recreation buildings, their grounds and institutional archives, bear silent witness to the noisy and lively recreational activities of past patients, staff and visitors. This chapter reconstructs these practices in twenty public and three private asylums from this period by examining a diverse range of sources, including archives, histories of asylums and newspaper articles.

    Workplace exposure to optical radiation from artificial sources is regulated in Europe under the Artificial Optical Radiation Directive 2006/25/EC implemented in the UK as The Control of Artificial Optical Radiation at Work Regulations 2010. The entertainment environment often presents an extremely complex situation for the assessment of occupational exposures. Multiple illumination sources, continuously changing illumination conditions and people moving during performances add further complexity to the assessment. This document proposes a methodology for assessing the risks arising from exposure to optical radiation and presents detailed case studies of practical assessment for two large entertainment venues.

  7. From early wireless to Everest.

    Science.gov (United States)

    Allen, A

    1998-01-01

    Medical information has been transmitted using wireless technologies for almost 80 years. A "wired wireless" electronic stethoscope was developed by the U.S. Army Signal Corps in the early 1920's, for potential use in ship-to-shore transmission of cardiac sounds. [Winters SR. Diagnosis by wireless. Scientific American June 11, 1921, p. 465] Today, wireless is used in a wide range of medical applications and at sites from transoceanic air flights to offshore oil platforms to Mt. Everest. 'Wireless LANs' are often used in medical environments. Typically, nurses and physicians in a hospital or clinic use hand-held "wireless thin client" pen computers that exchange patient information and images with the hospital server. Numerous companies, such as Fujitsu (article below) and Cruise Technologies (www.cruisetech.com) manufacture handheld pen-entry computers. One company, LXE, integrates radio-frequency (RF) enhanced hand-held computers specifically designed for production use within a wireless LAN (www.lxe.com). Other companies (Proxim, Symbol, and others) supply the wireless RF LAN infrastructure for the enterprise. Unfortunately, there have been problems with widespread deployment of wireless LANs. Perhaps the biggest impediment has been the lack of standards. Although an international standard (IEEE 802.11) was adopted in 1997, most wireless LAN products still are not compatible with the equipment of competing companies. A problem with the current standard for LAN adapters is that throughput is limited to 3 Mbps--compared to at least 10 Mbps, and often 100 Mbps, in a hard-wired Ethernet LAN. An II Mbps standard is due out in the next year or so, but it will be at least 2 years before standards-compliant products are available.

    Large-scale internal migration in China may be an important mechanism for the spread of HIV/sexually transmitted infections (STIs) because of the risk behaviours of migrants. We conducted a self-administered survey among 724 employees of a high-end entertainment centre in Kunshan, Jiangsu Province, China. Using logistic regression, we examined the association of hometown of origin (Kunshan city, elsewhere in Jiangsu Province, or another province in China) and consecutive years living in Kunshan with measures of HIV/STI risk behaviour. We found that increased time living in Kunshan was associated with lower odds of using condoms as contraception [odds ratio (OR) = 0.78, 95% confidence interval (CI): 0.64-0.95] and consistent condom use with a casual partner (OR = 0.66, 95% CI: 0.47-0.93), after controlling for gender, marital status age and income. The odds of having had an STI were significantly lower for Kunshan natives than those originally from outside provinces (OR = 0.25, 95% CI: 0.07-0.96), but increasing years living in Kunshan was not related to lower risk for an STI. Our findings do not support the hypothesis that migrants living far from home participate in higher risk behaviour than locals. Findings suggest that adaptation to local culture over time may increase HIV/STI risk behaviours, a troublesome finding.

    2015-12-01

    Research on smart homes has significantly increased in recent years owing to their considerably improved affordability and simplicity. However, the challenge is that people have different needs (or attitudes toward smart homes), and provision should be tailored to individuals. A few studies have classified the functions of smart homes. Therefore, the Kano model is first adopted as a theoretical base to explore whether the functional classifications of smart homes are attractive or necessary, or both. Second, three models and test user attitudes toward three function types of smart homes are proposed. Based on the Kano model, the principal results, namely, two "Attractive Quality" and nine "Indifferent Quality" items, are found. Verification of the hypotheses also indicates that the entertainment, security, and automation functions are significantly correlated with the variables "perceive useful" and "attitude." Cost consideration is negatively correlated with attitudes toward entertainment and automation. Results suggest that smart home providers should survey user needs for their product instead of merely producing smart homes based on the design of the builder or engineer.

    Khalil, Georges E; Rintamaki, Lance S

    2014-04-01

    This article investigates pathways between the exposure to an entertainment-education (E-E) television drama called Three Rivers and positive discussion of organ donation among viewers of the drama in the United States. A cross-sectional survey was conducted using an online advertising for a period of one week. Survey participants included 1325 adults living in the United States, who had viewed the first episode of Three Rivers on television. Data were collected on recall of events in the storyline, perceived entertainment value, perceived accuracy of the presented health information, rejection of organ donation myths and positive discussion of organ donation and the storyline. Covariates were registration for organ donation, membership to the donation or transplant community and demographic variables. Results show that viewers with high recall of the storyline were more likely to reject myths about organ donation and engage in pro-donation discussions with others. Perceived entertainment value and perceived accuracy acted as mediators in such relationships. The insertion of accurate health information in television drama may be effective in promoting positive discussions about organ donation and myth rejection. Recall of events from the televised E-E drama Three Rivers, entertainment value and accuracy perception were associated with positive discussion.

    2003-01-01

    The growing number of the elderly in industrialised countries is increasing the pressure on respective health care systems. This is one reason for recent trends in the development and expansion of home health care organisations. With Internet access available to everyone and the advent of wireless technologies, advanced telehomecare is a possibility for a large proportion of the population. In the near future, one of the authors plans to implement a home health care infrastructure for patients with congestive heart failure and patients with chronic obstructive pulmonary disease. The system is meant to support regular and ad-hoc measurements of medical parameters in patient homes and transmission of measurement data to the home health care provider. In this paper we look at network technologies that connect sensors and input devices in the patient home to a home health care provider. We consider wireless and Internet technologies from functional and security-related perspectives and arrive at a recommendation for our system. Security and usability aspects of the proposed network infrastructures are explored with special focus on their impact on the patient home.

    In this title, the authors leap into a novel paradigm of scalability and cost-effectiveness, on the basis of resource reuse. In a world with much abundance of wirelessly accessible devices, WSN deployments should capitalize on the resources already available in the region of deployment, and only augment it with the components required to meet new application requirements. However, if the required resources already exist in that region, WSN deployment converges to an assignment and scheduling scheme to accommodate for the new application given the existing resources. Such resources are polled

    Full Text Available The rural wireless networks are increasingly in demand by associations and autarchies to expand Internet access in this type of areas. The problem of such solutions centers not only in network deployment and its maintenance, but also in the equipment installation on clients, which always has big costs. This installation and configuration must be performed by a technician on site, so that the equipment can be integrated in the infrastructure. To try to mitigate this problem, it is presented a solution that allows the clients to install, with transparency, the device at home, reducing not only the cost for the management entity but also for the clients. This way, for info-excluded people or with new technology low experience level, it is the user that integrates himself in the network, making him part of the process, fostering the network usage.In this article are specified not only the system architecture but also the way that it works and how it obtains the desirable result. The tests made to the solution show the quickness, reliability and autonomy in the execution of the tasks, making it a benefit for rural wireless networks.This solution, by its robustness and simplicity, allowed an uptake to the IT by people who never thought to do it, namely an advanced age group (elderly who want to join the world of the new technologies

    It is believed that we are just at the beginning with wireless, and that a new age is dawning for this breakthrough technology. Thanks to several years of industrial manufacturing in mass-market applications such as cellular phones, wireless technology has nowadays reached a level of maturity that, combined with other achievements arising from different fields, such as information technology, artificial intelligence, pervasive computing, science of new materials, and micro-electro-mechanical systems (MEMS), will enable the realization of a networked stream-flow of real-time information, that will accompany us in our daily life, in a total seamless, transparent fashion. As almost any application scenario will require the deployment of complex, miniaturized, almost "invisible" systems, operating with different wireless standards, hard technological challenges will have to be faced for designing and fabricating ultra-low-cost, reconfigurable, and multi-mode heterogeneous smart micro-devices. But ongoing, unending progresses on wireless technology keeps the promise of helping to solve important societal problems in the health-care, safety, security, industry, environment sectors, and in general opening the possibility for an improved quality of life at work, on travel, at home, practically "everywhere, anytime".

    We applied Compressive Sensing to design an affordable, convenient Brain Machine Interface (BMI) measuring the high spatial density, and real-time process of Electroencephalogram (EEG) brainwaves by a Smartphone. It is useful for therapeutic and mental health monitoring, learning disability biofeedback, handicap interfaces, and war gaming. Its spec is adequate for a biomedical laboratory, without the cables hanging over the head and tethered to a fixed computer terminal. Our improved the intrinsic signal to noise ratio (SNR) by using the non-uniform placement of the measuring electrodes to create the proximity of measurement to the source effect. We computing a spatiotemporal average the larger magnitude of EEG data centers in 0.3 second taking on tethered laboratory data, using fuzzy logic, and computing the inside brainwave sources, by Independent Component Analysis (ICA). Consequently, we can overlay them together by non-uniform electrode distribution enhancing the signal noise ratio and therefore the degree of sparseness by threshold. We overcame the conflicting requirements between a high spatial electrode density and precise temporal resolution (beyond Event Related Potential (ERP) P300 brainwave at 0.3 sec), and Smartphone wireless bottleneck of spatiotemporal throughput rate. Our main contribution in this paper is the quality and the speed of iterative compressed image recovery algorithm based on a Block Sparse Code (Baranuick et al, IEEE/IT 2008). As a result, we achieved real-time wireless dynamic measurement of EEG brainwaves, matching well with traditionally tethered high density EEG.

    Budinger, Thomas F.

    2003-03-01

    This review is divided into three sections: technologies for monitoring physiological parameters; biosensors for chemical assays and wireless communications technologies including image transmissions. Applications range from monitoring high risk patients for heart, respiratory activity and falls to sensing levels of physical activity in military, rescue, and sports personnel. The range of measurements include, heart rate, pulse wave form, respiratory rate, blood oxygen, tissue pCO2, exhaled carbon dioxide and physical activity. Other feasible measurements will employ miniature chemical laboratories on silicon or plastic chips. The measurements can be extended to clinical chemical assays ranging from common blood assays to protein or specialized protein measurements (e.g., troponin, creatine, and cytokines such as TNF and IL6). Though the feasibility of using wireless technology to communicate vital signs has been demonstrated 32 years ago (1) it has been only recently that practical and portable devices and communications net works have become generally available for inexpensive deployment of comfortable and affordable devices and systems.

    What is home? A building, a physical and mental phenomenon, or a concept?  There are many homes and ways `to home oneself´. Many of us quite often dwell in other places than at home (as professional commuters between two places, as travellers staying in hotels, as children of divorced parents...... living one week with mom and one week with dad). We spend so much time in and between these movements and settings that we may even (have to learn how to) ‘home ourselves'. In other words, we may use different strategies in order to create a homely feeling and a certain sense of belonging. This paper...... expands on the notion that home indicates more than a house, but also responds to the overuse of the concept home. The aim of this article is to examine how home is done, stretched between everyday life, practices, dreams, loss and cultural ideas of home. My intention is not to remove home...

  8. Sensors for the Senses: Meaning-making via self-active entertainment experiences

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available In his ACM Computers in Entertainment article, titled "Artist and Audience: Emerging the Nano-entertainment experience", the author posited on how Inhabited Information Spaces, created as core catalyst of research, may be questioned as a multisensory future virtual work of art. This themed Human-Computer Interaction for Entertainment contribution for the EAI INTETAIN 2015 conference builds upon the earlier work by questioning meaning making from such self-active entertainment experiences. Contextually, self-active relates to actor empowerment via ICT, whilst entertainment refers to HCI paradigms that are fun, engaging, and enjoyable. Conceptualizing, designing and realizing alternative digital media entertainment situations in stage performance, interactive installations and exhibitions at leading Museums for Modern Art, National and International major events, contributed to development of a sensor-based system conceived as a platform to investigate meaning making having societal impact beyond art. The system involves arrays of selectable sensor profiles mixed and matched according to requirements. Sensing of human input can be through worn (biosignal e.g. EEG, ECG, EMG, GSR, held, and/or non-worn sensors (volumetric, linear and planar interface profiles. Mapping of sourced human data is to a variety of digital content including art-based (music making, digital painting, lighting effects, video games, Virtual Reality and robotic devices.

    Forsyth, Alasdair J M; Lennox, Jemma C; Emslie, Carol

    2016-10-01

    This qualitative research investigates the alcohol experiences of entertainers who perform within licensed premises. Previous, mainly quantitative, studies have found that entertainers, specifically musicians, are an occupational group who drink excessively. This qualitative study draws on a wider sample of entertainers to examine their accounts of drinking in the workplace and the explanations they provide for this. We conducted individual semi-structured interviews (n=24) with band-members, variety acts and DJs in Glasgow, Scotland. This revealed a workplace characterised by continual opportunities for often free alcohol consumption. Unlike most occupations, for entertainers 'drinking-on-the-job' was normative, expected, and sometimes encouraged by peers, the public, employers or sponsors. Entertainers also experienced performance-related incentives to drink before, during and/or after a show; including anxiety, matching their intoxication level to the audience's, and 'reward-drinking'. This qualitative research confirms the unique nature of the entertainer-alcohol link, even in comparison to that found within other leisure industry occupations. While providing some explanation as to why entertainers might drink excessively, participants' accounts also suggested potential strategies for avoiding the negative outcomes of workplace drinking.

    2007-01-01

    On June 14, 2006 three reports were published by the Institute of Medicine (IOM) in regards to "THE FUTURE OF EMERGENCY CARE IN THE UNITED STATES HEALTH SYSTEM". The three combined reports: Hospital-Based Emergency Care at the Breaking Point, Emergency Medical Services at the Crossroads and Emergency Care for Children Growing Pains, are a clear reflection of the state we currently face, even without a major disaster. Some key findings drawn from all three reports showed that the emergency care system is ill-prepared to handle a major one. For example, many of the 41 million citizens who do not have medical insurance end up using the Emergency Departments (ED) as their source of "regular" care and many of these EDs are at or over capacity, there is little surge capacity for a major event, whether it takes the form of a natural disaster, disease outbreak, or terrorist attack. If we had during the major disaster event, a "contagion" element, i.e. pandemic flu, then the problem would be even more complicated, since the "regular" hospital patient population would need to be isolated from these patients. If we add to this equation the length of time involved in the "current" process of vaccine creation and production (i.e. the volume of vaccines that would be required to be provided to the citizens of the world), the scenario does not look to promising. A new model is needed then to address these requirements. In the developed world we have a number of devices (e.g., radio, TV, Computers, telephones, mobile devices, etc.) and infrastructure (e.g., cable, wireless networks, etc.) that are already supplying the homes and the individuals with a large number of independent applications and different types of information. These stovepipes or independently developed family that include: tele-banking, Telehealth, tele-education, e-commerce, entertainment on demand, etc. when "connected" as an integrated set, may provide an ideal environment, where families may stay at home for

    2010-01-01

    Forearm crutches are frequently used in the rehabilitation of an injury to the lower limb. The recovery rate is improved if the patient correctly applies a certain fraction of their body weight (specified by a clinician) through the axis of the crutch, referred to as partial weight bearing (PWB). Incorrect weight bearing has been shown to result in an extended recovery period or even cause further damage to the limb. There is currently no minimally invasive tool for long-term monitoring of a patient's PWB in a home environment. This paper describes the research and development of an instrumented forearm crutch that has been developed to wirelessly and autonomously monitor a patient's weight bearing over the full period of their recovery, including its potential use in a home environment. A pair of standard forearm crutches are augmented with low-cost off-the-shelf wireless sensor nodes and electronic components to provide indicative measurements of the applied weight, crutch tilt and hand position on the grip. Data are wirelessly transmitted between crutches and to a remote computer (where they are processed and visualized in LabVIEW), and the patient receives biofeedback by means of an audible signal when they put too much or too little weight through the crutch. The initial results obtained highlight the capability of the instrumented crutch to support physiotherapists and patients in monitoring usage

    Drink driving is a significant public health concern, and contributes to many road fatalities worldwide. The current study is the first to examine the prevalence and correlates of drink driving behavior in a sample of night-time entertainment precinct attendees in Australia. Interviews were conducted with 4214 night-time entertainment precinct attendees in two metropolitan and three regional cities in Australia. Seven correlates of self-reported drink driving were examined: gender, age, occupation, blood alcohol concentration (BAC), alcohol consumed prior to attending a licensed venue, energy drink consumption, and other drug consumption. Fourteen percent of night-time entertainment precinct attendees reported drink driving in the past three months. Bivariate logistic regression models indicated that males were significantly more likely than females to report drink driving in the past three months. Blue-collar workers and sales/clerical/administrative workers were significantly more likely to report drink driving behavior in the past three months than white-collar workers. The likelihood of reporting drink driving during the three months prior to interview significantly increased as BAC on the current night out increased, and when patrons reported engaging in pre-drinking or other drug use. The multivariate model presented a similar pattern of results, however BAC and pre-drinking on the night of the interview were no longer independent significant predictors. Males, blue collar/sales/clerical/administrative workers, and illicit drug consumers were more likely to report engaging in drink driving behavior than their counterparts. Interventions should focus on addressing the considerable proportion night-time entertainment precinct attendees who report engaging in drink driving behavior. Copyright © 2016 Elsevier Ltd.

  1. Use of "entertainment" chimpanzees in commercials distorts public perception regarding their conservation status.

    Directory of Open Access Journals (Sweden)

    Kara K Schroepfer

    Full Text Available Chimpanzees (Pan troglodytes are often used in movies, commercials and print advertisements with the intention of eliciting a humorous response from audiences. The portrayal of chimpanzees in unnatural, human-like situations may have a negative effect on the public's understanding of their endangered status in the wild while making them appear as suitable pets. Alternatively, media content that elicits a positive emotional response toward chimpanzees may increase the public's commitment to chimpanzee conservation. To test these competing hypotheses, participants (n = 165 watched a series of commercials in an experiment framed as a marketing study. Imbedded within the same series of commercials was one of three chimpanzee videos. Participants either watched 1 a chimpanzee conservation commercial, 2 commercials containing "entertainment" chimpanzees or 3 control footage of the natural behavior of wild chimpanzees. Results from a post-viewing questionnaire reveal that participants who watched the conservation message understood that chimpanzees were endangered and unsuitable as pets at higher levels than those viewing the control footage. Meanwhile participants watching commercials with entertainment chimpanzees showed a decrease in understanding relative to those watching the control footage. In addition, when participants were given the opportunity to donate part of their earnings from the experiment to a conservation charity, donations were least frequent in the group watching commercials with entertainment chimpanzees. Control questions show that participants did not detect the purpose of the study. These results firmly support the hypothesis that use of entertainment chimpanzees in the popular media negatively distorts the public's perception and hinders chimpanzee conservation efforts.

  2. Transportation into narrative worlds: implications for entertainment media influences on tobacco use.

    Science.gov (United States)

    Green, Melanie C; Clark, Jenna L

    2013-03-01

    A growing body of research suggests that smoking portrayals in movies influence adolescent tobacco use. However, the mechanism for this influence remains unclear. The aim of this paper is to provide an overview of research on narrative transportation theory, particularly as applied to movies and smoking. We propose that this theory can provide a valuable framework for guiding research on the role of entertainment media in smoking and other addictive behaviors. We review empirical work on transportation theory and highlight the psychological mechanisms underlying transportation effects. 'Transportation into narrative worlds' refers to cognitive, emotional and imagery engagement into a narrative (including movies and entertainment media). We link this work with research on the effects of movie smoking. Research suggests that individuals who are more highly transported into narratives show greater attitude, belief and behavior change. Transportation effects work through reducing counterarguing, creating connections (identification and liking) with characters and increasing perceptions of realism and emotional involvement. We propose several future directions and research challenges for applying a transportation framework to the issue of entertainment media effects on smoking and tobacco disparities. Understanding factors contributing to transportation may provide a more nuanced view of who will be affected by movie smoking, and understanding the psychological processes underlying narrative persuasion may guide intervention efforts. Narrative transportation theory suggests that individuals' cognitive, emotional and imagery immersion in a narrative is a key mechanism of attitude, belief and behavior change. This theory provides a potentially generative and psychologically grounded framework for increasing knowledge about the boundary conditions and processes underlying the effects of entertainment media on tobacco use. © 2012 The Authors, Addiction © 2012 Society for

    2012-01-01

    A wireless damage location sensing system uses a geometric-patterned wireless sensor that resonates in the presence of a time-varying magnetic field to generate a harmonic response that will experience a change when the sensor experiences a change in its geometric pattern. The sensing system also includes a magnetic field response recorder for wirelessly transmitting the time-varying magnetic field and for wirelessly detecting the harmonic response. The sensing system compares the actual harmonic response to a plurality of predetermined harmonic responses. Each predetermined harmonic response is associated with a severing of the sensor at a corresponding known location thereof so that a match between the actual harmonic response and one of the predetermined harmonic responses defines the known location of the severing that is associated therewith.

    Full Text Available This article is the report of research conducted to answer two main questions; first, to what extent and under which forms using internet as entertainment is prevalent among users aged between 24 to 40 years in Tehran? And second has this kind of usage changed with passage of time (since the beginning of usage until the time of research? The research was designed and conducted with descriptive and qualitative method and the relevant data were gathered by using the techniques of deep interview with a sample (15 persons of the statistical population of users (the first generation of internet users in Tehran. The findings show that using internet as entertainment among the sample is usual usages which include chatting, blogging, music downloading, browsing the webs containing pornographic materials and Orcat in terms of leaning order. The responses of interviewees show that after the passage of ten years, using internet as entertainment has significantly declined. Chatting, browsing the webs containing pornographic material and cybernetic searching in terms of learning order have been mentioned the usual forms in early periods of internet usage.

  9. The werther effect of two celebrity suicides: an entertainer and a politician.

    Directory of Open Access Journals (Sweden)

    Jae-Hyun Kim

    Full Text Available PURPOSE: Suicide is a major health problem in Korea. Extensive media exposure of celebrity suicide may induce imitative suicide, a phenomenon called the Werther effect. We examined the increased suicide risk following the suicides of an entertainer and a politician, and identified the relative suicide risks. METHODS: News articles about the celebrity suicides were obtained from three major newspapers and analysed for quantitative and qualitative features. Imitative suicide risk was investigated by applying a Poisson time series autoregression model with suicide mortality data from the National Statistics Office for 1.5 years before and 1.5 years after each celebrity's suicide. The period with a significantly increased number of suicides immediately after the celebrity's suicide determined the Werther effect band. The relative risk during this period was examined for different ages, genders, and suicide methods. RESULTS: News reports were more numerous and they contained more positive definitions about the entertainer's suicide. The risk of suicide deaths rose markedly after both celebrity suicides. However, the Werther effect band was longer for the entertainer (6 weeks than for the politician (4 weeks. The relative suicide risk was significant for almost all ages and both genders during that of both individuals. Use of the same suicide method was a prominent risk factor after both celebrity suicides. CONCLUSIONS: Our results confirm the existence of imitative suicide behaviours, suggesting a facilitation effect of media reports. Guidelines for responsible media reporting need to be implemented to enhance public mental health in Korea.

  10. Heavy Sexual Content Versus Safer Sex Content: A Content Analysis of the Entertainment Education Drama Shuga.

    2016-12-01

    Extremely popular with Kenyan youth, the entertainment-education drama Shuga was designed with specific goals of promoting condom use, single versus multiple sexual partners, and destigmatization of HIV. Almost as soon as it aired, however, it generated controversy due to its extensive sexual themes and relatively explicit portrayal of sexual issues. To determine how safer sex, antistigma messages, and overall sexual content were integrated into Shuga, we conducted a content analysis. Results indicated that condom use and HIV destigmatization messages were frequently and clearly communicated. Negative consequences for risky sexual behavior were communicated over the course of the entire series. Messages about multiple concurrent partnerships were not evident. In addition, in terms of scenes per hour of programming, Shuga had 10.3 times the amount of sexual content overall, 8.2 times the amount of sexual talk, 17.8 times the amount of sexual behavior, and 9.4 times the amount of sexual intercourse as found in previous analysis of U.S. entertainment programming. Research is needed to determine how these factors may interact to influence adolescent viewers of entertainment education dramas.

  11. Travel Series as TV Entertainment: Genre characteristics and touristic views on foreign countries

    2009-04-01

    Full Text Available Why is it not the deprived developing country, but rather the tempting destination the host arrives in when guiding the audience in a travel series? And how can we explore the specific combination of entertainment and education that travel series represent? Basically the travel series genre is a hybrid of journalistic documentary, entertaining lifestyle series and TV ads and the different series put different emphasis on the different genre elements. Travel series represent a certain kind of mediated consumption and they reflect lifestyle identity in relation to touristic consumer cultures. Like other lifestyle series dealing with consumption products and lifestyle markers encompassing fashion, food, garden, design and interior that balance somewhere between journalism and advertising, travel series typically deal with destinations, travel modes, cultural experiences and food as commodities. To understand the cultural and democratic value of travel series as a popular TV genre in the context of public service broadcasting, it is not the fact that the series contain educative and enlightening information about foreign cultures told in an entertaining and popular way that are of my interest. Rather it is tourism and media consumer culture as such, one has to expound as valuable democratic and cultural practice. The article presents different matrices of the respectively cultural and consumer knowledge that the different types of travel series include.

    2017-01-01

    Background: The purpose of this study was to describe advertisements of children's entertainment products in a popular magazine, Parents, and to determine if they illustrated behavior that was physically active or sedentary. Methods: The sample was comprised of Parents magazines (January 2010 to December 2015). Coding involved determining if the advertisement was promoting sedentary or active behavior. Results: Nearly all of the 169 advertisements in the sample (n = 166; 97.6%) were for products that depicted sedentary behavior. The most common types of entertainment products advertised were DVDs (n = 72), plastic stacking products (n = 18), books (n=14), and electronic devices (n = 13). The most popular theme that appeared in the advertisements was the entertainment product would enhance intelligence (n = 85; 50.3%, 95% CI: 0.43-0.58). The overwhelming majority (n = 136; 80.5%. 95% CI: 0.76-0.87) of the advertisements involved the presence of a character. Conclusion: This type of advertising does not contribute to the nation's goals of increasing physical activity among youth.

    Full Text Available We study the energy-efficient configuration of multihop paths with automatic repeat request (ARQ mechanism in wireless ad hoc networks. We adopt a cross-layer design approach and take both the quality of each radio hop and the battery capacity of each transmitting node into consideration. Under certain constraints on the maximum tolerable transmission delay and the required packet delivery ratio, we solve optimization problems to jointly schedule the transmitting power of each transmitting node and the retransmission limit over each hop. Numerical results demonstrate that the path configuration methods can either significantly reduce the average energy consumption per packet delivery or considerably extend the average lifetime of the multihop route.

    Josephson junction parametric amplifiers are playing a crucial role in the readout chain in superconducting quantum information experiments. However, their integration with current 3D cavity implementations poses the problem of transitioning between waveguide, coax cables, and planar circuits. Moreover, Josephson amplifiers require auxiliary microwave components, like directional couplers and/or hybrids, that are sources of spurious losses and impedance mismatches that limit measurement efficiency and amplifier tunability. We have developed a wireless architecture for these parametric amplifiers that eliminates superfluous microwave components and interconnects. This greatly simplifies their assembly and integration into experiments. We present an experimental realization of such a device operating in the 9–11 GHz band with about 100 MHz of amplitude gain-bandwidth product, on par with devices mounted in conventional sample holders. The simpler impedance environment presented to the amplifier also results in increased amplifier tunability.

    Wireless sensor network (WSN) is an ad-hoc network technology comprising even thousands of autonomic and self-organizing nodes that combine environmental sensing, data processing, and wireless networking. The applications for sensor networks range from home and industrial environments to military uses. Unlike the traditional computer networks, a WSN is application-oriented and deployed for a specific task. WSNs are data centric, which means that messages are not send to individual nodes but to geographical locations or regions based on the data content. A WSN node is typically battery powered and characterized by extremely small size and low cost. As a result, the processing power, memory, and energy resources of an individual sensor node are limited. However, the feasibility of a WSN lies on the collaboration between the nodes. A reference WSN node comprises a Micro-Controller Unit (MCU) having few Million Instructions Per Second (MIPS) processing speed, tens of kilobytes program memory, few kilobytes data m...

    Clements, Samuel L.; Carroll, Thomas E.; Hadley, Mark D.

    2011-04-01

    With the wide array of home area network (HAN) options being presented as solutions to smart grid challenges for the home, it is time to compare and contrast their strengths and weaknesses. This white paper examines leading and emerging HAN technologies. The emergence of the smart grid is bringing more networking players into the field. The need for low consistent bandwidth usage differs enough from the traditional information technology world to open the door to new technologies. The predominant players currently consist of a blend of the old and new. Within the wired world Ethernet and HomePlug Green PHY are leading the way with an advantage to HomePlug because it doesn't require installing new wires. In the wireless the realm there are many more competitors but WiFi and ZigBee seem to have the most momentum.

  17. Proposal of Wireless Traffic Control Schemes for Wireless LANs

    Science.gov (United States)

    Hiraguri, Takefumi; Ichikawa, Takeo; Iizuka, Masataka; Kubota, Shuji

    This paper proposes two traffic control schemes to support the communication quality of multimedia streaming services such as VoIP and audio/video over IEEE 802.11 wireless LAN systems. The main features of the proposed scheme are bandwidth control for each flow of the multimedia streaming service and load balancing between access points (APs) of the wireless LAN by using information of data link, network and transport layers. The proposed schemes are implemented on a Linux machine which is called the wireless traffic controller (WTC). The WTC connects a high capacity backbone network and an access network to which the APs are attached. We evaluated the performance of the proposed WTC and confirmed that the communication quality of the multimedia streaming would be greatly improved by using this technique.

    Switching techniques have been first proposed as a spacial diversity techniques. These techniques have been shown to reduce considerably the processing load while letting multi-antenna systems achieve a specific target performance. In this thesis, we take a different look at the switching schemes by implementing them for different other wireless applications. More specifically, this thesis consists of three main parts, where the first part considers a multiuser environment and an adaptive scheduling algorithm based on the switching with post-selection scheme for statistically independent but non-identically distributed channel conditions. The performance of this switched based scheduler is investigated and a multitude of performance metrics are presented. In a second part, we propose and analyze the performance of three switched-based algorithms for interference reduction in the downlink of over-loaded femtocells. For instance, performance metrics are derived in closed-form and these metrics are used to compare these three proposed schemes. Finally in a third part, a switch based opportunistic channel access scheme is proposed for a cognitive radio system and its performance is analyzed in terms of two new proposed metrics namely the average cognitive radio access and the waiting time duration.

    NASA field center Marshall Space Flight Center (Huntsville, AL), has invested in advanced wireless sensor technology development. Developments for a wireless microcontroller back-end were primarily focused on the commercial Synapse Wireless family of devices. These devices have many useful features for NASA applications, good characteristics and the ability to be programmed Over-The-Air (OTA). The effort has focused on two widely used sensor types, mechanical strain gauges and thermal sensors. Mechanical strain gauges are used extensively in NASA structural testing and even on vehicle instrumentation systems. Additionally, thermal monitoring with many types of sensors is extensively used. These thermal sensors include thermocouples of all types, resistive temperature devices (RTDs), diodes and other thermal sensor types. The wireless thermal board will accommodate all of these types of sensor inputs to an analog front end. The analog front end on each of the sensors interfaces to the Synapse wireless microcontroller, based on the Atmel Atmega128 device. Once the analog sensor output data is digitized by the onboard analog to digital converter (A/D), the data is available for analysis, computation or transmission. Various hardware features allow custom embedded software to manage battery power to enhance battery life. This technology development fits nicely into using numerous additional sensor front ends, including some of the low-cost printed circuit board capacitive moisture content sensors currently being developed at Auburn University.

    2016-08-01

    Full Text Available A wireless rechargeable sensor network (WRSN consists of sensor nodes that can harvest energy emitted from wireless chargers for refilling their batteries so that the WRSN can operate sustainably. This paper assumes wireless chargers are equipped with directional antennas, and are deployed on grid points of a fixed height to propose two heuristic algorithms solving the following wireless charger deployment optimization (WCDO problem: how to deploy as few as possible chargers to make the WRSN sustainable. Both algorithms model the charging space of chargers as a cone and calculate charging efficiency according power regression expressions complying with the Friis transmission equation. The two algorithms are the greedy cone covering (GCC algorithm and the adaptive cone covering (ACC algorithm. The GCC (respectively, ACC algorithm greedily (respectively, adaptively generates candidate cones to cover as many as possible sensor nodes. Both algorithms then greedily select the fewest number of candidate cones, each of which corresponds to the deployment of a charger, to have approximate solutions to the WCDO problem. We perform experiments, conduct simulations and do analyses for the algorithms to compare them in terms of the time complexity, the number of chargers deployed, and the execution time.

    Jibaja-Weiss, Maria L; Volk, Robert J

    2007-01-01

    Decision aids have been developed by using various delivery methods, including interactive computer programs. Such programs, however, still rely heavily on written information, health and digital literacy, and reading ease. We describe an approach to overcome these potential barriers for low-literate, underserved populations by making design considerations for poor readers and naïve computer users and by using concepts from entertainment education to engage the user and to contextualize the content for the user. The system design goals are to make the program both didactic and entertaining and the navigation and graphical user interface as simple as possible. One entertainment education strategy, the soap opera, is linked seamlessly to interactive learning modules to enhance the content of the soap opera episodes. The edutainment decision aid model (EDAM) guides developers through the design process. Although designing patient decision aids that are educational, entertaining, and targeted toward poor readers and those with limited computer skills is a complex task, it is a promising strategy for aiding this population. Entertainment education may be a highly effective approach to promoting informed decision making for patients with low health literacy.

    2011-01-01

    Entertainment-education (E-E) may offer an effective way to reduce risky behavior by modeling healthy behaviors. Although there is some empirical evidence to support the effectiveness of the E-E strategy, much of this research has been conducted in countries with different media landscapes than that of the United States and controlled experiments in this context are rare. Moreover, empirical tests of the relative effectiveness of E-E messages and other message formats are needed. In this study, 437 undergraduates participated in a three-wave panel experiment in which they viewed one of three programs (E-E, education, or entertainment). Safer sex intentions and behaviors were measured several days before, immediately following, and 2 weeks after exposure. Results demonstrate that effects of exposure to this E-E program vary depending on gender and past experience with sexual intercourse. In particular, females and those who had not initiated sexual intercourse showed the strongest effects. Discussion of theoretical implications and suggestions for future research are provided.

  6. The challenges of social marketing of organ donation: news and entertainment coverage of donation and transplantation.

    Science.gov (United States)

    Harrison, Tyler R; Morgan, Susan E; Chewning, Lisa V

    2008-01-01

    While great strides have been made in persuading the public to become potential organ donors, actual behavior has not yet caught up with the nearly universally favorable attitudes the public expresses toward donation. This paper explores the issue by situating the social marketing of organ donation against a broader backdrop of entertainment and news media coverage of organ donation. Organ donation storylines are featured on broadcast television in medical and legal dramas, soap operas, and other television serials approximately four times per month (not including most cable networks), and feature storylines that promote myths and fears of the organ donation process. National news and other non-fictionalized coverage of organ donation are even more common, with stories appearing over twenty times a month on average. These stories tend to be one-dimensional and highly sensationalized in their coverage. The marketing of organ donation for entertainment essentially creates a counter-campaign to organ donation, with greater resources and reach than social marketers have access to. Understanding the broader environmental context of organ donation messages highlights the issues faced by social marketing campaigns in persuading the public to become potential donors.

    2008-12-01

    Makgabaneng is an entertainment-education radio serial drama written and produced in Botswana to promote prevention of HIV. This effort is part of the national response to HIV/AIDS. Broadcast of the serial drama began in August 2001, and two new 15-minute episodes air each week. We examined associations between exposure to Makgabaneng and outcomes related to HIV testing, including stigmatizing attitudes, intention to be tested, talking with a partner about testing, and testing for HIV, among 555 sexually active respondents. The four measures of exposure to Makgabaneng were frequency of listening, duration of listening, talking about the program, and attentiveness to and identification with relevant characters. Data were collected approximately 18 months after the drama began airing. We found positive associations between exposure to the program and intermediate outcomes, including lower level of stigmatizing attitudes, stronger intention to have HIV testing, and talking to a partner about testing. Although associations were identified with all four measures of exposure, increased duration of listening was associated with more positive outcomes than the other measures. This finding suggests that longer term exposure to entertainment-education programming may be important for behavior change.

    Purpose Suicide is a major health problem in Korea. Extensive media exposure of celebrity suicide may induce imitative suicide, a phenomenon called the Werther effect. We examined the increased suicide risk following the suicides of an entertainer and a politician, and identified the relative suicide risks. Methods News articles about the celebrity suicides were obtained from three major newspapers and analysed for quantitative and qualitative features. Imitative suicide risk was investigated by applying a Poisson time series autoregression model with suicide mortality data from the National Statistics Office for 1.5 years before and 1.5 years after each celebrity’s suicide. The period with a significantly increased number of suicides immediately after the celebrity’s suicide determined the Werther effect band. The relative risk during this period was examined for different ages, genders, and suicide methods. Results News reports were more numerous and they contained more positive definitions about the entertainer’s suicide. The risk of suicide deaths rose markedly after both celebrity suicides. However, the Werther effect band was longer for the entertainer (6 weeks) than for the politician (4 weeks). The relative suicide risk was significant for almost all ages and both genders during that of both individuals. Use of the same suicide method was a prominent risk factor after both celebrity suicides. Conclusions Our results confirm the existence of imitative suicide behaviours, suggesting a facilitation effect of media reports. Guidelines for responsible media reporting need to be implemented to enhance public mental health in Korea. PMID:24386428

    Entertainment-education has proved to be an engaging medium through which to explore health and social issues in populations. Given the popularity of the zombie theme in popular culture it is no surprise therefore that the Centers for Disease Control and Prevention adopted this theme in an effort to engage youth and young adults in emergency preparedness. However, an earlier observational study involving elementary school children based on this premise raised concerns that it may have unexpectedly promoted a focus on firearms. A randomized control study involving 89 children (average age 10.4 years) was therefore conducted to explore this possibility in more depth. One group was exposed to a natural disaster scenario, while the other group was exposed to the zombie pandemic theme. When subsequently asked to prepare emergency kit lists, participants in the zombie themed scenario were 15.84 times as likely to include firearms in their lists compared with participants who were exposed to the natural disaster scenario. Although the sample size in this study was small, it is suggested that future interventions using entertainment-education need to explore all aspects of the messages implicit in their chosen medium, rather than just focusing on one element.

    The European directive 2006/25/EC on minimum health and safety requirements regarding the exposure of workers to the risks arising from optical radiation provides for risk assessment in workplaces. This is particularly important in entertainment, where intentional exposure to spotlights may be required for periods of 8 hours per working day. The aim of the study was to provide the lighting engineers with information, relative to the risks associated with spotlights, to help them to estimate the risks a priori of a lighting plan. This study consisted of determining the risks associated with 63 different spotlights, then distributing them into 4 groups of risks defined by the standard EN 62471, in calculating their permissible minimal exposure distance, corresponding to the use of 1 and 5 spotlights for a daily exposure time of 8 hours. This study highlighted that spotlights may cause health problems for entertainment workers. The classification proposed by the standard EN 62471 is not sufficient to estimate the risks of a lighting plan. Furthermore, the permissible minimal exposure distance and the permissible maximal exposure time do not constitute relevant parameters to reduce the risks to acceptable values. (authors)

    The purpose of this qualitative study is to understand how a sample of visiting nurses experienced the practice of home health nursing in the inner city and how they perceived the anticipated introduction of wireless, pen-based computing into their practice. Focus groups were held with visiting nurses 1 week before the introduction of the wireless, pen-based computers. The data were analyzed using Strauss and Corbin's (1990) method for concept development. The following central concepts emerged from the focus groups with visiting nurses: "Missing contact in the field," "Consumption of time writing on forms," "Using the computer to help with the practice of home health nursing," and "Home nursing is a lifeline." These concepts, based on the commentaries by visiting nurses, help one to understand the problems encountered by visiting nurses in the delivery of home health care, identify ways to incorporate evolving technologies to enhance nursing practice, and consider approaches to computer skill acquisition.

    The development of smart cities has been the epicentre of many researchers' efforts during the past decade. One of the key requirements for smart city networks is mobility and this is the reason stable, reliable and high-quality wireless communications are needed in order to connect people and devices. Most research efforts so far, have used different kinds of wireless and sensor networks, making interoperability rather difficult to accomplish in smart cities. One common solution proposed in the recent literature is the use of software defined networks (SDNs), in order to enhance interoperability among the various heterogeneous wireless networks. In addition, SDNs can take advantage of the data retrieved from available sensors and use them as part of the intelligent decision making process contacted during the resource allocation procedure. In this paper, we propose an architecture combining heterogeneous wireless networks with social networks using SDNs. Specifically, we exploit the information retrieved from location based social networks regarding users' locations and we attempt to predict areas that will be crowded by using specially-designed machine learning techniques. By recognizing possible crowded areas, we can provide mobile operators with recommendations about areas requiring datacell activation or deactivation.

    The growing need for underwater observation and subsea monitoring systems has stimulated considerable interest in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. This communication technology is expected to play an important role in investigating climate change, in monitoring biological, biogeochemical, evolutionary, and ecological changes in the sea, ocean, and lake environments, and in helping to control and maintain oil production facilities and harbors using unmanned underwater vehicles (UUVs), submarines, ships, buoys, and divers. However, the present technology of underwater acoustic communication cannot provide the high data rate required to investigate and monitor these environments and facilities. Optical wireless communication has been proposed as the best alternative to meet this challenge. Models are presented for three kinds of optical wireless communication links: (a) a line-of-sight link, (b) a modulating retroreflector link, and (c) a reflective link, all of which can provide the required data rate. We analyze the link performance based on these models. From the analysis, it is clear that as the water absorption increases, the communication performance decreases dramatically for the three link types. However, by using the scattered light it was possible to mitigate this decrease in some cases. It is concluded from the analysis that a high-data-rate underwater optical wireless network is a feasible solution for emerging applications such as UUV-to-UUV links and networks of sensors, and extended ranges in these applications could be achieved by applying a multi-hop concept.

    2008-01-01

    A lightweight, low-power camera dart has been designed and tested for context imaging of sampling sites and ground surveys from an aerobot or an orbiting spacecraft in a microgravity environment. The camera penetrators also can be used to image any line-of-sight surface, such as cliff walls, that is difficult to access. Tethered cameras to inspect the surfaces of planetary bodies use both power and signal transmission lines to operate. A tether adds the possibility of inadvertently anchoring the aerobot, and requires some form of station-keeping capability of the aerobot if extended examination time is required. The new camera penetrators are deployed without a tether, weigh less than 30 grams, and are disposable. They are designed to drop from any altitude with the boost in transmitting power currently demonstrated at approximately 100-m line-of-sight. The penetrators also can be deployed to monitor lander or rover operations from a distance, and can be used for surface surveys or for context information gathering from a touch-and-go sampling site. Thanks to wireless operation, the complexity of the sampling or survey mechanisms may be reduced. The penetrators may be battery powered for short-duration missions, or have solar panels for longer or intermittent duration missions. The imaging device is embedded in the penetrator, which is dropped or projected at the surface of a study site at 90 to the surface. Mirrors can be used in the design to image the ground or the horizon. Some of the camera features were tested using commercial "nanny" or "spy" camera components with the charge-coupled device (CCD) looking at a direction parallel to the ground. Figure 1 shows components of one camera that weighs less than 8 g and occupies a volume of 11 cm3. This camera could transmit a standard television signal, including sound, up to 100 m. Figure 2 shows the CAD models of a version of the penetrator. A low-volume array of such penetrator cameras could be deployed from an

    Full Text Available Social media has phenomenally changed the communication landscape. Particularly social network sites have received enormous popularity and user acceptance globally. The business model of many social network sites is based on advertising. The survival of these social network sites depends on the user acceptance of advertising appearing on these websites. Users usually accept the advertising which is consistent with their motivations for using social network sites. The current study examines the underlying dimensions of entertainment motivation for using social network sites and their impact on user acceptance of social network advertising. Analysis of data from 450 university students show entertainment motivation for using social network sites a multidimensional (SNSs construct consisting of enjoyment, social escapism, relaxation and pass time factors. Furthermore, the results exhibit that SNSs entertainment motivation partially impacts user acceptance of social network advertising.

    Full Text Available Abstract Background Few studies have examined the benefits of regular physical activity, and risks of sedentary behaviour, in young children. This study investigated associations between participation in sports and screen-entertainment (as components of physical activity and sedentary behaviour, and emotional and behavioural problems in this population. Methods Cross-sectional analysis of data from 13470 children (50.9% boys participating in the nationally representative UK Millennium Cohort Study. Time spent participating in sports clubs outside of school, and using screen-entertainment, was reported by the child's mother at child age 5 years, when mental health was also measured using the Strengths and Difficulties Questionnaire. Results 45% of children did not participate in sport clubs and 61% used screen-entertainment for ≥ 2 hours per day. Children who participated in sport had fewer total difficulties; emotional, conduct, hyperactivity-inattention and peer relationship problems; and more prosocial behaviours. These relationships were similar in boys and girls. Boys and girls who used screen-entertainment for any duration, and participated in sport, had fewer emotional and behavioural problems, and more prosocial behaviours, than children who used screen-entertainment for ≥ 2 hours per day and did not participate in sport. Conclusions Longer durations of screen-entertainment usage are not associated with mental health problems in young children. However, our findings suggest an association between sport and better mental health. Further research based on longitudinal data is required to examine causal pathways in these associations and to determine the potential role of this and other forms of physical activity in preventing mental health disorders.

    We propose a novel intervention to train the speed and accuracy of attention orienting and eye movements in Autism Spectrum Disorder (ASD). Training eye movements and attention could not only affect those important functions directly, but could also result in broader improvement of social communication skills. To this end we describe a system that would allow ASD children to improve their fixation skills while playing a computer game controlled by an eye tracker. Because this intervention will probably be time consuming, this system should be designed to be used at homes. To make this possible, we propose an implementation based on wireless and dry electrooculography (EOG) technology. If successful, this system would develop an approach to therapy that would improve clinical and behavioral function in children and adults with ASD. As our initial steps in this direction, here we describe the design of a computer game to be used in this system, and the predictions of gaze position from EOG data recorded while a subject played this game.

    Full Text Available Network coverage is one of the basic issues for information collection and data processing in ZigBee-based wireless sensor networks. Each node may be randomly distributed in a monitoring area, reflecting the network event of tracking in ZigBee network applications. This paper presents the development and coverage evaluation of a ZigBee-based wireless network application. A stack structure node available for home service integration is proposed, and all data of sensing nodes with an adaptive weighted fusion (AWF processing are passed to the gateway and through the gateway to reexecute packet processing and then reported to the monitoring center, which effectively optimize the wireless network to the scale of the data processing efficiency. The linear interpolation theory is used for background graphical user interface so as to evaluate the working status of each node and the whole network coverage case. A testbed has been created for validating the basic functions of the proposed ZigBee-based home network system. Network coverage capabilities were tested, and packet loss and energy saving of the proposed system in longtime wireless network monitoring tasks were also verified.

    2015-10-01

    Full Text Available The research and the implementation of home automation are getting more popular because the Internet of Things holds promise for making homes smarter through wireless technologies. The installation of systems based on wireless networks can play a key role also in the extension of the smart grid towards smart homes, that can be deemed as one of the most important components of smart grids. This paper proposes a fuzzy-based solution for smart energy management in a home automation wireless network. The approach, by using Bluetooth Low Energy (BLE, introduces a Fuzzy Logic Controller (FLC in order to improve a Home Energy Management (HEM scheme, addressing the power load of standby appliances and their loads in different hours of the day. Since the consumer is involved in the choice of switching on/off of home appliances, the approach introduced in this work proposes a fuzzy-based solution in order to manage the consumer feedbacks. Simulation results show that the proposed solution is efficient in terms of reducing peak load demand, electricity consumption charges with an increase comfort level of consumers. The performance of the proposed BLE-based wireless network scenario are validated in terms of packet delivery ratio, delay, and jitter and are compared to IEEE 802.15.4 technology.

    2017-10-01

    Wireless smart sensing is now widely used in various applications such as health monitoring and structural monitoring. In conventional wireless sensor nodes, significant power is consumed in wirelessly transmitting the raw data. Smart sensing adds local intelligence to the sensor node and reduces the amount of wireless data transmission via on-node digital signal processing. While the total power consumption is reduced compared to conventional wireless sensing, the power consumption of the digital processing becomes as dominant as wireless data transmission. This paper reviews the state-of-the-art energy-efficient digital and wireless IC design techniques for reducing the power consumption of the wireless smart sensor node to prolong battery life and enable self-powered applications.

    Full Text Available This paper presents visually enhanced sports entertainment applications: AR Baseball Presentation System and Interactive AR Bowling System. We utilize vision-based augmented reality for getting immersive feeling. First application is an observation system of a virtual baseball game on the tabletop. 3D virtual players are playing a game on a real baseball field model, so that users can observe the game from favorite view points through a handheld monitor with a web camera. Second application is a bowling system which allows users to roll a real ball down a real bowling lane model on the tabletop and knock down virtual pins. The users watch the virtual pins through the monitor. The lane and the ball are also tracked by vision-based tracking. In those applications, we utilize multiple 2D markers distributed at arbitrary positions and directions. Even though the geometrical relationship among the markers is unknown, we can track the camera in very wide area.

    2011-11-01

    Takotsubo cardiomyopathy (TC) is an uncommon entity. It is known to occur in the setting of extreme catecholamine release and results in left ventricular dysfunction without evidence of angiographically definable coronary artery disease. There have been no published reports of TC occurring with visual stimuli, specifically 3-dimensional (3D) entertainment. We present a 55-year-old woman who presented to her primary care physician's office with extreme palpitations, nausea, vomiting, and malaise movie at her local theater. Her electrocardiogram demonstrated ST elevations in aVL and V1, prolonged QTc interval, and T-wave inversions in leads I, II, aVL, and V2-V6. Coronary angiography revealed angiographically normal vessels, elevated left ventricular filling pressures, and decreased ejection fraction with a pattern of apical ballooning. The presumed final diagnosis was TC, likely due to visual-auditory-triggered catecholamine release causing impaired coronary microcirculation. © 2011 Wiley Periodicals, Inc.

    Full Text Available Focusing on the often neglected individual modes of consumption and ascriptions of meaning, I propose a theoretical and conceptual framework for the analysis of the diversity of the use and appropriation of the boys' love (BL genre. Within the framework of theories of media gratification, I bring together key elements of BL fandom, such as playing with masculinities, and central concepts of entertainment research. To assess these concepts' appropriateness and to do justice to the transnational phenomenon that BL has become, I also consider qualitative interviews conducted in Japan and Germany. The gratifications sought and gained by BL fans (fujoshi and fudanshi, rotten girls and boys vary, including the physiological (arousal, the social (exchange, belonging, the cognitive (parasocial interaction, and the aesthetic (immersion. My empirical findings highlight the diversity of BL use, while my conceptual framework additionally works as a reference for a comparison of these use patterns and other media preferences as well as global trends of media consumption.

    There is little research describing how intoxication levels change throughout the night in entertainment districts. This research aims to describe levels of alcohol intoxication across multiple Australian metropolitan and regional nightlife districts. This study was conducted in the night-time entertainment districts of three metropolitan cities (Sydney, Melbourne and Perth) and two regional cities (Wollongong and Geelong) in Australia. Data collection occurred approximately fortnightly in each city on a Friday or Saturday night between 8 pm and 5 am. Brief structured interviews (3-10 min) and breathalyser tests were undertaken in busy thoroughfares over six months. Of the 7037 individuals approached to participate in the study, 6998 [61.8% male, mean age 24.89 years (standard deviation 6.37; range 18-73)] agreed to be interviewed. There was a linear increase in blood alcohol concentration (BAC) levels throughout the night.

    Incidences of violence are elevated in night-time entertainment districts. Research suggests that safety-related behavioural strategies adopted while drinking can reduce negative alcohol-related outcomes. The current study investigates the use of safety strategies and its association with experiences of violence among patrons from the general population. Patron interviews (N = 3949) were conducted in and around licenced venues in Newcastle (New South Wales) and Geelong (Victoria) during peak trading hours (Friday and Saturday, 21:00-01:00 h). Participants (mean age = 24.3, SD = 5.8; male 54.4%) were asked to report what measures, if any, they used to keep safe when drinking and whether they had been involved in a violent incident in the last 12 months. After controlling for patron demographics and location, the use of multiple (more than one) safety strategies was significantly associated with reduced odds of involvement in a violent incident (odds ratio = 0.64, 95% confidence interval 0.49-0.85, P = 0.002). Significant gender differences were observed in the number and type of safety strategies reported. Increasing the number of safety-related behaviours during drinking occasions is associated with a small but significant reduction in experiencing alcohol-related harms, such as violence.

    Full Text Available Wireless infrared communications can be defined as the propagation of light waves in free space using infrared radiation whose range is 400–700 nm. This range corresponds to frequencies of hundreds of terahertz, which is high for higher data rate applications. Wireless infrared is applied for higher data rates applications such as wireless computing, wireless video and wireless multimedia communication applications. Introduced by Gfeller, this field has grown with different link configurations, improved transmitter efficiency, increased receiver responsivity and various multiple access techniques for improved quality. Errors are caused because of background light, which causes degradation overall system performance. Error correction techniques are used to remove the errors caused during transmission. This study provides a brief account on field theory used for error correction in wireless infrared systems. The results are produced in terms of bit error rate and signal-to-noise ratio for various bit lengths to show the ability of encoding and decoding algorithms.

    Wireless technologies are getting widely used in various industrial processes for equipment condition monitoring, process measurement and other applications. In case of Nuclear Power Plant (NPP), it is required to review applicability of the wireless technologies for maintaining plant reliability, preventing equipment failure, and reducing operation and maintenance costs. Remote sensors, mobile technology and two-way radio communication may satisfy these needs. The application of the state of the art wireless technologies in NPPs has been restricted because of the vulnerability for the Electromagnetic Interference and Radio Frequency Interference (EMI/RFI) and cyber security. It is expected that the wireless technologies can be applied to the nuclear industry after resolving these issues which most of the developers and vendors are aware of. This paper presents an overview and information on general wireless deployment in nuclear facilities for future application. It also introduces typical wireless plant monitoring system application in the existing NPPs

    Full Text Available Wireless body sensor networks based on ultra-wideband radio have recently received much research attention due to its wide applications in health-care, security, sports and entertainment. Accurate localization is a fundamental problem to realize the development of effective location-aware applications above. In this paper the problem of constrained state estimation for individual localization in wireless body sensor networks is addressed. Priori knowledge about geometry among the on-body nodes as additional constraint is incorporated into the traditional filtering system. The analytical expression of state estimation with linear constraint to exploit the additional information is derived. Furthermore, for nonlinear constraint, first-order and second-order linearizations via Taylor series expansion are proposed to transform the nonlinear constraint to the linear case. Examples between the first-order and second-order nonlinear constrained filters based on interacting multiple model extended kalman filter (IMM-EKF show that the second-order solution for higher order nonlinearity as present in this paper outperforms the first-order solution, and constrained IMM-EKF obtains superior estimation than IMM-EKF without constraint. Another brownian motion individual localization example also illustrates the effectiveness of constrained nonlinear iterative least square (NILS, which gets better filtering performance than NILS without constraint.

    2007-12-01

    We have developed an automated system for analyzing Hi-net seismograms for earthquake early warning (EEW) in Japan. Because of limitations imposed by station spacing, our system generally cannot issue an EEW to areas within about 30 km distance of the earthquake's hypocenter. We estimate that about 10 times the number of stations would be needed to issue an EEW in these areas, but the overhead would be cost prohibitive for governmental agencies. The practical deployment of EEW in Japan has started in October, 2007 and millions of people are expected to purchase and install the receiving/alarm unit of EEW. Since most of these units are connected to internet and equipped with a CPU and memory, we realized that the addition of an inexpensive seismometer and digitizer would transform the receiver into a real-time seismic observatory, which we are calling a home seismometer; these modifications only cost about $20. The home seismometer can help to generate alerts at the time of the occurrence of a large local earthquake by using locally observed data. Also, home seismograms can be used to estimate the amplification factor in sedimentary layers, which will be used to determine the site correction for shaking intensity by comparing the waveform data from the home seismometer against those from nearby Hi-net or K-NET stations. This amplification factor, which is essentially the basis of a shake-map with very-high spatial resolution, will help to establish a safety index of houses/buildings for large earthquakes, since a structure located at a site with large seismic amplification can be damaged more seriously than those with small amplification factors. The installation of home seismometers will create an extremely dense seismic network that is without precedence. We are developing an automatic system that collects waveform data from all home seismometer installations, calculates earthquake parameters in real-time, and then sends back alarms signals based on computed

    A compact, ambulatory biometric data acquisition system has been developed for space and commercial terrestrial use. BioWATCH (Bio medical Wireless and Ambulatory Telemetry for Crew Health) acquires signals from biomedical sensors using acquisition modules attached to a common data and power bus. Several slots allow the user to configure the unit by inserting sensor-specific modules. The data are then sent real-time from the unit over any commercially implemented wireless network including 802.11b/g, WCDMA, 3G. This system has a distributed computing hierarchy and has a common data controller on each sensor module. This allows for the modularity of the device along with the tailored ability to control the cards using a relatively small master processor. The distributed nature of this system affords the modularity, size, and power consumption that betters the current state of the art in medical ambulatory data acquisition. A new company was created to market this technology.

    Full Text Available Rudimentary brain machine interface has existed for the gaming industry. Here, we propose a wireless, real-time, and smartphone-based electroencephalogram (EEG system for homecare applications. The system uses high-density dry electrodes and compressive sensing strategies to overcome conflicting requirements between spatial electrode density, temporal resolution, and spatiotemporal throughput rate. Spatial sparseness is addressed by close proximity between active electrodes and desired source locations and using an adaptive selection of N active among 10N passive electrodes to form m-organized random linear combinations of readouts, m≪N≪10N. Temporal sparseness is addressed via parallel frame differences in hardware. During the design phase, we took tethered laboratory EEG dataset and applied fuzzy logic to compute (a spatiotemporal average of larger magnitude EEG data centers in 0.3 second intervals and (b inside brainwave sources by Independent Component Analysis blind deconvolution without knowing the impulse response function. Our main contributions are the fidelity of quality wireless EEG data compared to original tethered data and the speed of compressive image recovery. We have compared our recovery of ill-posed inverse data against results using Block Sparse Code. Future work includes development of strategies to filter unwanted artifact from high-density EEGs (i.e., facial muscle-related events and wireless environmental electromagnetic interferences.

    2007-01-21

    The recent advances in microsensor and semiconductor technology have opened a new field within computer science: the networking of small-sized sensors which are capable of sensing, processing, and communicating. Such wireless sensor networks offer new applications in the areas of habitat and environment monitoring, disaster control and operation, military and intelligence control, object tracking, video surveillance, traffic control, as well as in health care and home automation. It is likely that the deployed sensors will be battery-powered, which will limit the energy capacity significantly. Thus, energy efficiency becomes one of the main challenges that need to be taken into account, and the design of energy-efficient algorithms is a major contribution of this thesis. As the wireless communication in the network is one of the main energy consumers, we first consider in detail the characteristics of wireless communication. By using the embedded sensor board (ESB) platform recently developed by the Free University of Berlin, we analyze the means of forward error correction and propose an appropriate resync mechanism, which improves the communication between two ESB nodes substantially. Afterwards, we focus on the forwarding of data packets through the network. We present the algorithms energy-efficient forwarding (EEF), lifetime-efficient forwarding (LEF), and energy-efficient aggregation forwarding (EEAF). While EEF is designed to maximize the number of data bytes delivered per energy unit, LEF additionally takes into account the residual energy of forwarding nodes. In so doing, LEF further prolongs the lifetime of the network. Energy savings due to data aggregation and in-network processing are exploited by EEAF. Besides single-link forwarding, in which data packets are sent to only one forwarding node, we also study the impact of multi-link forwarding, which exploits the broadcast characteristics of the wireless medium by sending packets to several (potential

    Wireless sensor networks (WSN) based on the IEEE 802.15.4 Personal Area Network and ZigBee Pro 2007 standards are finding increasing use in home automation and smart energy markets providing a framework for interoperable software. The Wireless Connections in Space Project, funded by the NASA Engineering and Safety Center, is developing technology, metrics and requirements for next-generation spacecraft avionics incorporating wireless data transport. The team from Stennis Space Center and Mobitrum Corporation, working under a NASA SBIR grant, has developed techniques for embedding plug-and-play software into ZigBee WSN prototypes implementing the IEEE 1451 Transducer Electronic Datasheet (TEDS) standard. The TEDS provides meta-information regarding sensors such as serial number, calibration curve and operational status. Incorporation of TEDS into wireless sensors leads directly to building application level software that can recognize sensors at run-time, dynamically instantiating sensors as they are added or removed. The Ames Research Center team has been experimenting with this technology building demonstration prototypes for on-board health monitoring. Innovations in technology, software and process can lead to dramatic improvements for managing sensor systems applied to Developmental and Flight Instrumentation (DFI) aboard aerospace vehicles. A brief overview of the plug-and-play ZigBee WSN technology is presented along with specific targets for application within the aerospace DFI market. The software architecture for the sensor nodes incorporating the TEDS information is described along with the functions of the Network Capable Gateway processor which bridges 802.15.4 PAN to the TCP/IP network. Client application software connects to the Gateway and is used to display TEDS information and real-time sensor data values updated every few seconds, incorporating error detection and logging to help measure performance and reliability in relevant target environments

    Full Text Available The applied cultural analysis work presented in this article was conducted with independent professionals who work in a flexible time-space format – known as telework – for the entertainment, new media, and arts sector in the Los Angeles area. Most participants are associates of the production and post-production boutique “Studio Can” as well as the curatorial new media and arts nonprofit organization “PalMarte.” When working in a flexible time-space format, boundaries between leisure/family life and work at home, or personal and public realms, tend to become blurred. This blurred context involves a web of cultural complexity that exists behind the materialization of boundaries. Through empirical material, this article examines rhythms and mechanisms between flexibility and stability, unveiling a viscous consistency of everyday life. This work helps to better understand the relation between leisure/family life and work at home, as well as stability and change, to rethink these realms and how they relate to each other but also how they transform one another. Although culturally different, these realms are bridged through the material culture that surrounds them. As conveyors, objects (such as a heating pad and activities culturally transport participants between realms. Research methods combined time-diaries, interviews, observation, visual ethnography, and autoethnography. While applying academic knowledge into a non-academic setting to rethink realms and how they relate and transform each other in a bridged relationship, this work is also an invitation to rethink the relationship between the realms of academia and non-academia.

    To explore risk factors associated with induced abortion among sexually active female entertainment workers (FEWs) in Cambodia. Cross-sectional study. Phnom Penh and Siem Reap, Cambodia. This study included 556 FEWs aged 18-47 years randomly selected from entertainment establishments in the two cities in 2014 using a two-stage cluster sampling method. Data were collected through face-to-face interviews using a structured questionnaire. History of induced abortion during the time working as a FEW. Of the total sample, 45.6% reported currently using a contraceptive method with condom (42.4%) being the most common method, followed by pills (25.6%). One-fourth (25%) of the respondents reported having been pregnant at least once, and 21.4% reported having at least one induced abortion during the time working as a FEW. After controlling for other covariates in a multivariate logistic regression model, FEWs with a history of induced abortion remained significantly more likely to be currently working in a karaoke bar (AOR=1.75, 95% CI 1.10 to 2.78), to have worked longer as a FEW (AOR=1.42, 95% CI 1.06 to 1.43), to have had a greater number of sexual partners in the past 12 months (AOR=1.86, 95% CI 1.02 to 1.54), to be currently using a contraceptive method (AOR=1.52, 95% CI 1.01 to 2.29), to be able to find condoms when they needed them (AOR=2.03, 95% CI 1.09 to 3.82), and to report inconsistent condom use with non-commercial partners in the past 3 months (AOR=1.62, 95% CI 1.06 to 3.44). This study highlights the high rates of unwanted pregnancies that ended in induced abortions among FEWs in Cambodia. Access of FEWs to quality sexual and reproductive healthcare services is deemed a high priority. Integrated interventions to improve sexual and reproductive health among these vulnerable women should be tailored to reach the most-at-risk groups. Published by the BMJ Publishing Group Limited.

    Linkages between HIV and reproductive health (RH) among female entertainment workers (EWs) have not been addressed well in most developing countries. In Cambodia, there has been considerable research on HIV epidemiology among EWs. However, there have been limited studies on RH and specifically factors related to abortion. We examine socio-behavioral characteristics, and RH practices as determinants of abortion among Cambodian EWs. A survey was conducted in Siem Reap and Battambang and Phnom Penh provinces/city among EWs in September 2012. Trained female interviewers administered the survey to 595 EWs. Two-stage cluster sampling was used to select EWs. Bivariate associations were examined using chi-squares; univariate and multivariate logistic regression were used to assess factors independently associated with reporting having at least one abortion while working as an EW. Three-quarters (75 %) of EWs were sexually active, of which nearly one third reported at least one abortion while working as an EW. About 40 % of EWs reported recent an abortion in the past six months. Contraceptive use in the past year was low. Factors found to be independently associated with reporting a recent abortion included: ages 25-29 (OR = 2.2, 95 % CI: 1.2-4.0), living with spouse/cohabitated partner (OR = 2.2, 95 % CI: 1.1-4.2), longer duration of entertainment work (OR = 4.8, 95 % CI: 2.5-9.2), higher number of partners (OR = 4.4, 95 % CI: 2.2-8.7) and being a karaoke worker (OR = 2.2, 95 % CI: 1.1-4.4). This study highlights a high proportion of EWs reporting abortion. While HIV vulnerability of EWs has been clearly established, broader RH needs have gone largely unrecognized and not prioritized. Though HIV/RH integrated initiatives have been introduced by the HIV program, challenges for EWs with multiple risks from professional and partners are profound. Therefore, there is an urgent need for practical programmatic approaches to help address their RH needs.

    Full Text Available This paper presents a direct wireless battery charging system. The output current of the series-series compensated wireless power transfer (SS-WPT system is used as a current source, and the output voltage of AC-DC converter controls the current source. Therefore, the proposed wireless battery charging system needs no battery charging circuit to carry out charging profiles, and can solve space constraints and thermal problems in many battery applications. In addition, the proposed wireless battery charging system can implement easily most other charging profiles. In this paper, the proposed wireless battery charging system is implemented and the feasibility is verified experimentally according to constant-current constant-voltage charging profile or multi-step current charging profile.

    2000-01-01

    Full Text Available There is at present a worldwide effort to develop next-generation wireless communication systems. It is envisioned that many of the future wireless systems will incorporate considerable signal-processing intelligence in order to provide advanced services such as multimedia transmission. In general, wireless channels can be very hostile media through which to communicate, due to substantial physical impediments, primarily radio-frequency interference and time-arying nature of the channel. The need of providing universal wireless access at high data-rate (which is the aim of many merging wireless applications presents a major technical challenge, and meeting this challenge necessitates the development of advanced signal processing techniques for multiple-access communications in non-stationary interference-rich environments. In this paper, we present some key advanced signal processing methodologies that have been developed in recent years for interference suppression in wireless networks. We will focus primarily on the problem of jointly suppressing multiple-access interference (MAI and intersymbol interference (ISI, which are the limiting sources of interference for the high data-rate wireless systems being proposed for many emerging application areas, such as wireless multimedia. We first present a signal subspace approach to blind joint suppression of MAI and ISI. We then discuss a powerful iterative technique for joint interference suppression and decoding, so-called Turbo multiuser detection, that is especially useful for wireless multimedia packet communications. We also discuss space-time processing methods that employ multiple antennas for interference rejection and signal enhancement. Finally, we touch briefly on the problems of suppressing narrowband interference and impulsive ambient noise, two other sources of radio-frequency interference present in wireless multimedia networks.

    Energy Technology Data Exchange (ETDEWEB)

    Simpson, M.L.; Sayler, G.S. (Univ. Tennessee)

    2003-11-10

    The goal of this project was the development of a family of wireless, single-chip, luminescence-sensing devices to solve a number of difficult distributed measurement problems in areas ranging from environmental monitoring and assessment to high-throughput screening of combinatorial chemistry libraries. These wireless luminescence integrated sensors (WLIS) consist of a microluminometer, wireless data transmitter, and RF power input circuit all realized in a standard integrated circuit (IC) process with genetically engineered, whole-cell, bioluminescent bioreporters encapsulated and deposited on the IC. The end product is a family of compact, low-power, rugged, low-cost sensors. As part of this program they developed an integrated photodiode/signal-processing scheme with an rms noise level of 175 electrons/second for a 13-minute integration time, and a quantum efficiency of 66% at the 490-nm bioluminescent wavelength. this performance provided a detection limit of < 1000 photons/second. Although sol-gel has previously been used to encapsulate yeast cells, the reaction conditions necessary for polymerization (primarily low pH) have beforehand proven too harsh for bacterial cell immobilizations. Utilizing sonication methods, they have were able to initiate polymerization under pH conditions conductive to cell survival. both a toluene bioreporter (Pseudomonas putida TVA8) and a naphthalene bioreporter (Pseudomonas fluorescens HK44) were successfully encapsulated in sol-gel and shown to produce a fairly significant bioluminescent response. In addition to the previously developed naphthalene- and toluene-sensitive bioreporters, they developed a yeast-based xenoestrogen reporter. This technology has been licensed by Micro Systems Technologies, a startup company in Dayton, Ohio for applications in environmental containments monitoring, and for detecting weapons of mass destruction (i.e. homeland security).

    Can stories succeed where traditional forms of diplomacy have faltered? This study examined whether a primetime drama could impact American viewers’ knowledge, attitudes, and behavior with respect to U.S. foreign policy and funding by surveying 173 viewers of an episode of Law & Order: SVU (“Witness”). Additionally, this study sought to uncover which theoretical construct — involvement with a specific character or involvement with the narrative more generally (transportation) — best predicted impact. The fictional character in question was Nardelie, a woman forced to flee the Democratic Republic of the Congo after repeated rape by militias vying for “conflict minerals,” so named because control of these valuable minerals has triggered numerous conflicts. Separate regression analyses suggested a positive relationship between impact of the storyline and both theoretical constructs. However, when both constructs were entered into a single regression, involvement with Nardelie was the stronger predictor of knowledge (e.g., conflict minerals, sexual violence, and asylum issues) and current or future behavior (i.e., discussing global health) while transportation was the stronger predictor of attitudes (i.e., support for aid). This suggests that, while correlated, these constructs do not completely overlap. Implications of these results and the use of entertainment education in public diplomacy are discussed.

    2009-02-01

    To examine the concurrent effects of exposure to movie smoking and tobacco marketing receptivity on adolescent smoking onset and progression. Cross-sectional study of 4524 northern New England adolescents aged 10-14 in 1999 with longitudinal follow-up of 2603 baseline never-smokers. Cross-sectional outcomes included ever tried smoking and higher level of lifetime smoking among 784 experimenters. The longitudinal outcome was onset of smoking among baseline never-smokers two years later. Movie smoking exposure was modelled as four population quartiles, tobacco marketing receptivity included two levels-having a favourite tobacco advert and wanting/owning tobacco promotional items. All analyses controlled for sociodemographics, other social influences, personality characteristics of the adolescent and parenting style. In the full cross-sectional sample, 17.5% had tried smoking; both exposure to movie smoking and receptivity to tobacco marketing were associated with having tried smoking. Among experimental smokers, the majority (64%) were receptive to tobacco marketing, which had a multivariate association with higher level of lifetime smoking (movie smoking did not). In the longitudinal study 9.5% of baseline never-smokers tried smoking at follow-up. Fewer never-smokers (18.5%) were receptive to tobacco marketing. Movie smoking had a multivariate association with trying smoking (receptivity to tobacco marketing did not). The results suggest separate roles for entertainment media and tobacco marketing on adolescent smoking. Both exposures deserve equal emphasis from a policy standpoint.

  1. Meaningful, entertaining, popular and ‘Bavarian’: art into design in nineteenth century Munich

    Directory of Open Access Journals (Sweden)

    Stefan Muthesius

    2014-12-01

    Full Text Available Among European regional stereotypes few come across as strongly and consistently as ‘Bavaria’. Its strength is derived from the ways in which it appears to be firmly and comprehensively grounded in its land and its people. This article traces the way in which some of the stereotype’s associated forms and images, principally those related to the domestic environment, were first conceived during the nineteenth century. The principal claim is that it was the nineteenth century artists, architects and designers in the Kunststadt Munich, who, helped by the critics, arrived at very specific valorisations of their designs, which could then be applied in an essentialist way to all artefacts of the region, old or new. The article divides the Munich design activities into two phases. During the 1850s designers aimed for a poetic and ‘volkstümlich / popular’ kind of decoration of common objects, including scenes from Bavarian ‘folk’ poetry. In the second phase, during the 1870s and 1880s, interest turned more directly to the domestic environment of Alpine houses, valorising a plain wooden character. Clearly, an absolute belief in in a primeval and unchanging ‘Bavaria’ cannot be entertained any more. But neither should one classify it all as modern kitsch. The latter attitude must be the reason why the subject has hardly been touched on in the copious art histories of Munich so far.

  2. Portrayals of schizophrenia by entertainment media: a content analysis of contemporary movies.

    Owen, Patricia R

    2012-07-01

    Critics of entertainment media have indicated that cinematic depictions of schizophrenia are stereotypic and characterized by misinformation about symptoms, causes, and treatment. The pervasiveness and nature of misinformation are difficult to ascertain because of the lack of empirically based studies of movies portraying schizophrenia. This study analyzed portrayals of schizophrenia in contemporary movies to ascertain prevalence of stereotypes and misinformation about schizophrenia. English-language movies featuring at least one main character with schizophrenia that were released for showing in theaters between 1990 and 2010 were analyzed for depictions of schizophrenia. Two researchers independently rated each character with a checklist that assessed demographic characteristics, symptoms and stereotypes, causation, and treatment. Forty-two characters from 41 movies were identified, a majority of whom were male and Caucasian. Most characters displayed positive symptoms of schizophrenia. Delusions were featured most frequently, followed by auditory and visual hallucinations. A majority of characters displayed violent behavior toward themselves or others, and nearly one-third of violent characters engaged in homicidal behavior. About one-fourth of characters committed suicide. Causation of schizophrenia was infrequently noted, although about one-fourth of movies implied that a traumatic life event was significant in causation. Of movies alluding to or showing treatment, psychotropic medications were most commonly portrayed. The finding that misinformation and negative portrayals of schizophrenia in contemporary movies are common underscores the importance of determining how viewers interpret media messages and how these interpretations inform attitudes and beliefs both of the general public and of people with schizophrenia.

  3. Educational storylines in entertainment television: audience reactions toward persuasive strategies in medical dramas.

    2015-04-01

    Medical television drama series provide an important source of health information. This form of entertainment-education (E-E) can be used to influence knowledge, attitudes, and behaviors toward health-related issues. In the literature, E-E is generally regarded as a persuasive strategy in itself, whereas in an increasing number of E-E programs, several different persuasive strategies are used. An important question is how the audience ethically evaluates these strategies. The aim of the present study is to examine viewers' ethical judgments toward the use of three persuasive strategies in E-E: product placement, framing, and persuasion toward a controversial position. A survey among 525 viewers of 5 popular medical dramas demonstrates that viewers evaluate the use of the currently investigated attitudinal statements about potential persuasive strategies in E-E as being immoral and that viewers prefer neutral storylines. Adopting a strategy that viewers find inappropriate may interfere with the intended prosocial effects of E-E. A broader understanding of the appropriate and inappropriate uses of persuasive strategies in E-E is indispensable for effective E-E productions.

  4. Framing in Entertainment-Education: Effects on Processes of Narrative Persuasion.

    2017-12-01

    Nowadays, entertainment-education (E-E) is often used as a persuasive strategy to stimulate prosocial behavior. Although E-E is mostly regarded as a persuasive strategy in itself, in an increasing number of E-E programs several persuasive strategies are used to communicate the educational message to the audience. This study investigates the effects of a strategy widely used in health communication, but not previously studied in the field of E-E: framing. To this means we examined the effect of two different ways an E-E message can be framed: by emphasizing either the losses of not performing the behavior in question or the gains of performing this behavior. A serial multiple mediation model showed that framing affected intention to refrain from drunk cycling via counterarguing and attitude toward drunk cycling; the use of a gain frame decreased counterarguing, which decreased the attitude toward drunk cycling. This subsequently resulted in a higher intention to refrain from this behavior. Implications of these results are discussed.

  5. Cultural diversity and entertainment in the media ambience of the spectacle

    2017-06-01

    Full Text Available http://dx.doi.org/10.5007/2175-7984.2017v16n35p178 The scope of this figurative-procedural analysis is the correlation between communication and cultural diversity. Firstly, it is discussed the role played by image in contemporary Western culture. It is affirmed, then, that the audiovisual production integrates the transactions between sociohuman and machinic networks, which not only support and question the forms and means of symbolization, but also correspond to a late example of this same interaction. More specifically, the analysis falls on the interaction of audiovisual production with other modes of production and circulation of symbolic goods, especially in the setting of mediatic environments, in the very act of recomposing other modes of symbolization as contents of these socio-technical environments. The examination of the convergence of televisual media and the carnival ludic-aesthetic eventgenre of the Rio de Janeiro Samba Schools Parade demonstrates that in the reconstitution of the spectacle-show’s ambience, it is possible to observe mechanisms of contemporary entertainment, and especially the mechanism of cultural valuing of a given social expression.

  6. Identification With Characters, Elaboration, and Counterarguing in Entertainment-Education Interventions Through Audiovisual Fiction.

    2016-01-01

    The aim of this article is to further knowledge of the explanatory processes of narrative persuasion in the field of health communication, using data obtained in a research study of entertainment-education based on audiovisual fiction. Participating in the study were 208 young persons between the ages of 14 and 20, randomly distributed to three different groups. Each of the groups was exposed to a different episode of the Colombian television series Revelados, desde todas las posiciones. The results showed that greater identification with the main character of the episode transmitting a prevention message was associated with greater cognitive elaboration, which in turn led to more favorable attitudes toward the topics addressed. However, counterarguing was not observed to play a significant mediating role. The findings of this study allow us to conclude that getting people to think and reflect can help persuade them, which suggests that narrative persuasion models and dual models of rhetorical persuasion can be compatible in certain contexts, such as when messages are designed in such a way that characters make explicit arguments that endorse a prosocial message through dialogues.

    Modified rectangular compact microstrip patch antenna having finite ground plane is proposed in this paper. Wideband Microstrip Antenna (WMSA) is achieved by corner cut and inserting air gaps inside the edges of the radiating patch having finite ground plane. The obtained impedance bandwidth for 10 dB return loss for the operating frequency f{sub 0} = 2.09 GHz is 28.7 % (600 MHz), which is very high as compared to the bandwidth obtained for the conventional microstrip antenna. Compactness with wide bandwidth of this antenna is practically useful for the wireless communication systems.

    Full Text Available Abstract Background Wireless local area networks (WLANs are considered the next generation of clinical data network. They open the possibility for capturing clinical data in a prehospital setting (e.g., a patient's home using various devices, such as personal digital assistants, laptops, digital electrocardiogram (EKG machines, and even cellular phones, and transmitting the captured data to a physician or hospital. The transmission rate is crucial to the applicability of the technology in the prehospital setting. Methods We created two separate WLANs to simulate a virtual local are network environment such as in a patient's home or an emergency room (ER. The effects of different methods of data transmission, number of clients, and roaming among different access points on the file transfer rate were determined. Results The present results suggest that it is feasible to transfer small files such as patient demographics and EKG data from the patient's home to the ER at a reasonable speed. Encryption, user control, and access control were implemented and results discussed. Conclusions Implementing a WLAN in a centrally managed and multiple-layer-controlled access control server is the key to ensuring its security and accessibility. Future studies should focus on product capacity, speed, compatibility, interoperability, and security management.

    The average age of population is predicted to be raised universally but the number of nursing staff is not increasing at the same rate. This leads us to the situation where, e.g., we have too many patients for one nurse. On the other hand, sparse population in some regions, such as Northern or Eastern Finland, causes a severe problem that doctors are far away from patient. In this paper, we summarize the possibilities and applications that utilize wireless technologies in healthcare sector and which can be useful in nursing activities. The use of new innovations is one way to solve the problems that are based on the expected lack of professional staff in the future. Despite of the very natural hospital link, the developed technical solutions have applications outside hospital. Remote care of aging people and other special groups need to be done daily and almost real-time. Keeping people home instead of hospital is one way to decrease the entire care costs. In addition to the obvious human context, we derive some other applications where we can benefit wireless nursing and remote sensing techniques.

    Full Text Available A home embodies a sensorial space that is layered with personal memories and traces of history. The success of a home in providing a strong sense of place depends on various factors such as geographical location, climatic conditions, and occupants’ world-views and perceptions. This paper explores Muslims’ perceptions of privacy, modesty and hospitality within their homes through their lived experiences. This case study focuses on three Muslim families living in Australian designed homes within the same suburb of Brisbane, Australia. The study provides prefatory insight into the ways in which these families perform their daily activities and entertain their guests without jeopardizing their privacy needs. The study examines the significance of modesty in the design of Muslim homes as a means by which family members are able to achieve optimum privacy while simultaneously extending hospitality to guests inside and outside their homes. The findings of this study provide opportunities too, for expanding research into culturally adaptable housing systems to help meet the changing needs of Australian multicultural society.

    Entertainment magazine websites provide a continuous stream of celebrity news accessed by over 13 million unique viewers each month. Celebrities' experiences of pregnancy and new motherhood appear to be popular topics within these media outlets; however, little research has investigated the content of this coverage. In this study, investigators coded articles (N=387) published between August 1, 2007 and August 1, 2008 on three popular entertainment magazine websites. Relatively few articles about celebrities' pregnancies discussed weight (13%) or shape (30%), and an even smaller proportion (6.2%) included any discussion of postpartum body dissatisfaction. This suggests a gap between portrayal of celebrities' pregnancies and postpartum experiences and those of non-celebrity women. This disparity is concerning as it might lead to unrealistic expectations about pregnancy and postpartum for both pregnant readers and a more general audience. This study provides important initial information about the messages these media provide regarding pregnancy-related appearance. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Attempts to develop a Wireless Health Advanced Mobile Bio-diagnostic System (abbreviated as WHAM-BioS) have arisen from the need to monitor the health status of patients under long-term care programs. The proposed WHAM-BioS as presented here was developed by integrating various technologies: nano/MEMS technology, biotechnology, network/communication technology, and information technology. The biochips proposed not only detect certain diseases but will also report any abnormal status readings on the patient to the medical personnel immediately through the network system. Since long-term home care is typically involved, the parameters monitored must be analyzed and traced continuously over a long period of time. To minimize the intrusion to the patients, a wireless sensor embedded within a wireless network is highly recommended. To facilitate the widest possible use of various biochips, a smart sensor node concept was implemented. More specifically, various technologies and components such as built-in micro power generators, energy storage devices, initialization processes, no-waste bio-detection methodologies, embedded controllers, wireless warning signal transmissions, and power/data management were merged and integrated to create this novel technology. The design methodologies and the implementation schemes are detailed. Potential expansions of this newly developed technology to other applications regimes will be presented as well.

    Networks of wirelessly communicating sensors are a promising technology for future data-gathering systems in both civilian and military applications including medical and environmental monitoring and surveillance, home security and industry. Optical wireless communication is a potential solution for the links, particularly thanks to the small and lightweight hardware and low power consumption. A noteworthy feature of optical wireless communication at ultraviolet wavelengths is that scattering of radiation by atmospheric particles is significant, so that the backscattering of light by these particles can function as a vehicle of communication as if numerous tiny reflecting mirrors were placed in the atmosphere. Also, almost no solar radiation penetrates the atmosphere in this spectral band, which is hence called the solar blind ultraviolet spectrum, so that very large field-of-view receivers can be used. In this paper we present a model of a non-line-of-sight (NLOS) optical wireless sensor network operating in the solar blind ultraviolet spectrum. The system feasibility is evaluated and found to facilitate miniature operational sensor networks. The problem of multi-access interference is addressed and the possibility of overcoming it using WDM diversity methods is investigated.

    The number of patients that require medical assistance is increasing each day while staff-patient ratio is not balanced causing issues such as treatment delay and often leads to patient dissatisfaction. Besides that, healthcare devices are getting complex and challenging for it to be handled and interpreted personally by patient. Lack of staff and challenges in operating the medical devices not only affect patient in hospital but also caused problem to home care patients that require full attention and constant monitoring. This urges for a development of new method or technology. At present, Wireless Sensor Network (WSN) is gaining interest as one of the major components in enabling Internet of Things (IoT) since it offers low cost, low power monitoring besides reducing devices dependency on wires or cable. Although, WSN is initially developed for military application, nowadays, it is being integrated into various applications such as environmental monitoring, smart monitoring and agricultural monitoring. The idea of wireless monitoring with low power consumption motivates researchers to discover the possibility of deploying wireless sensor network for mission critical application such as in healthcare applications. This paper presents the details on the design and development of wireless sensor network using Waspmote from Libelium Inc. for mission critical applications such as healthcare applications.

    The distributed wireless quantum communication network (DWQCN) has a distributed network topology and transmits information by quantum states. In this paper, we present the concept of the DWQCN and propose a system scheme to transfer quantum states in the DWQCN. The system scheme for transmitting information between any two nodes in the DWQCN includes a routing protocol and a scheme for transferring quantum states. The routing protocol is on-demand and the routing metric is selected based on the number of entangled particle pairs. After setting up a route, quantum teleportation and entanglement swapping are used for transferring quantum states. Entanglement swapping is achieved along with the process of routing set up and the acknowledgment packet transmission. The measurement results of each entanglement swapping are piggybacked with route reply packets or acknowledgment packets. After entanglement swapping, a direct quantum link between source and destination is set up and quantum states are transferred by quantum teleportation. Adopting this scheme, the measurement results of entanglement swapping do not need to be transmitted specially, which decreases the wireless transmission cost and transmission delay. (general)

    Extraction of electromagnetic energy by an antenna from impinging external radiation is at the basis of wireless communications and wireless power transfer (WPT). The maximum of transferred energy is ensured when the antenna is conjugately matched, i.e., when it is resonant and it has an equal coupling with free space and its load. This condition, however, can be easily affected by changes in the environment, preventing optimal operation of a WPT system. Here, we introduce the concept of coherently enhanced WPT that allows us to bypass this difficulty and achieve dynamic control of power transfer. The approach relies on coherent excitation of the waveguide connected to the antenna load with a backward propagating signal of specific amplitude and phase. This signal creates a suitable interference pattern at the load resulting in a modification of the local wave impedance, which in turn enables conjugate matching and a largely increased amount of extracted energy. We develop a simple theoretical model describing this concept, demonstrate it with full-wave numerical simulations for the canonical example of a dipole antenna, and verify experimentally in both near-field and far-field regimes.
