Smartphone technologies can support older adults in their daily lives as they age in place at home. However, they may struggle to use these technologies which impacts acceptance, adoption, and sustainable use. Peer to peer community learning has the potential to support older adults to learn using (smartphone) technologies. This paper studies such a learning community approach and how it can support older adults to learn using and adopt the smartphone application GoLivePhone. This technology assists older adults in their daily living by supporting them through fall detection and activity tracking. In particular, the interface of this application can evolve and adapt as older adults become more knowledgeable during the use process or as their abilities change. This paper shows a field study with seven older adults learning and using the GoLivePhone technology through a living lab approach. These older adults participated in this research in a technology learning community that was set-up for research purposes. For this we used ordinary Samsung A3 smartphones with the simplified GoLivePhone software, particularly designed for older adults. At the end of the learning class we conducted an additional focus group to both explore factors facilitating older adults to learn using this technology and to identify their main personal drivers and motivators to start and adopt this technology. We collected qualitative data via open questions and audio recording during the focus group. This collected data was subject to a thematic analysis, coding was primarily performed by the first author, and reviewed by the other authors. We provide insights into how peer to peer community learning can contribute, and found both super-users and recall tools to be helpful to support sustainable use of smartphone technology to support older adults to age in place.

Study Design: Mixed methods study including quantitative data analysis and qualitative analysis of semi-structured interviews. Objectives: Utilizing information and communication technology can facilitate professional communication within health care on a global scale. This study aimed to identify the educational and peer-to-peer communication needs of craniomaxillofacial (CMF) surgeons across the globe, determine preferred modes of communication, and assess technological and other barriers to online education and peer-to-peer communication. Methods: We performed semi-structured videoconference interviews of 92 CMF surgeons from around the globe, with the largest number in the Asia/Pacific region, the Middle East, and Latin America. We triangulated quantitative summaries with qualitative themes to improve validity and enable a more comprehensive understanding of participant perspectives. Results: The interviews revealed 3 main areas of technology use: new surgical technology, technology that enables information exchange, and communication technology. When asked about technology and communication platforms used in the course of their work, 33 participants (36%) mentioned PubMed or other journal-related sites; 25% recalled using YouTube as a resource; 23% described conducting internet searches using Google or other search engines; 21% used WhatsApp groups; and 11% used closed Facebook groups. Conclusion: CMF surgeons embraced communication technologies that allowed them to quickly obtain knowledge especially on new surgical technology, discuss cases on demand, and maintain strong communication with their global peers.

In this paper, a distributed peer-to-peer (P2P) electricity trading model was proposed to study economic interactions between load aggregators (LAs) and microgrid operators (MGOs) considering network losses in a distribution system. In this model, the economic interactions among market participants were formulated as a Nash bargaining game, where LAs and MGOs can bargain with each other on the trading volume of electricity and payment. To achieve the Nash bargaining solution, the game was divided into two sub-problems: social welfare maximization and payment bargaining. Then, the alternating direction method of multipliers was used to solve the two sub-problems with limited information exchange. Finally, we tested the proposed model on a 12 × 12 km2 distribution system, and the results verify its effectiveness.

Long Time

The trend towards using IEC61850 standards in feeder terminal unit (FTU) design is inexorable, but at present in China, IEC60870-5-104 is mostly used in distribution automatic system (DAS) information exchange. Thus it can be seen that IEC61850 standard will coexist with IEC60870-5 standard for a long time. IEC61850-80-1 provides the method of exchanging information from IEC61850 CDC-based data model using IEC60870-5-101 or IEC60870-5-104. This paper makes a brief analysis on the structure of DAS based on IEC61850, proposes the information model of FTU in accordance to IEC61850 and maps the information model to IEC60870-5-104 using IEC61850-80-1, which takes the advantage of IEC60870-5-104’s excellent real-time performance to realize peer-to-peer communication between FTUs.
