Gabriele Di Simone, A. Pietrosanto, A. Espírito-Santo, B. Ribeiro, V. Paciello
Smart cities and smart homes are driving economic growth and improving the quality of people's life by enabling local development and harnessing technologies, especially the ones leading to smart outcomes and connectivity. Application of smart solutions will enable human living environments to use technology, information and data to improve infrastructures and services in the behalf of human beings. The welfare of elderly people living alone, at their homes, or, in rest houses, can significantly be improved with the introduction of these smart solutions. Wireless indoor tracking of elderly people is an important feature together with the DLMS/COSEM protocol. Above all using low power devices to assist and monitoring them. The paper highlights implementation in the real world, proposing a method that can be suited in a large range of cases thanks to the scene analysis. An indoor scalable infrastructure allows the tracking method to be implemented incrementally with different performances, where optimal accuracy comes from an adaptable threshold. The method has been tested in different environments using both simulations and direct measurements. Result from the proposed method are compared with the KNN method.

Marta Manovel López, Miguel Maldonado López, I. D. L. T. Díez, J. C. P. Jimeno, Miguel López Coronado, Joel Rodrigues
This paper aims to evaluate OphthalDSS, a new mobile Decision Support System (DSS) for red eye diseases diagnosis, and presents the results after evaluating the Quality of Experience (QoE) by medical students of the University of Valladolid, Spain. The main utilities that OphthalDSS offers, will be a study guide for physicians and medical students, and a clinical decision support system for primary care professionals. The decision algorithm will be implemented by an Android mobile App and the QoE will be evaluated by a short inquiry. The algorithm OphthalDSS is capable of diagnosing more than 30 eye's anterior segment diseases. A total of 67 medical students have evaluated the QoE. The different blocks in which the survey is organized have achieved a score of at least the mean value. Most of the surveyed students agree with that OphthalDSS does the function that they expected, the information presented in it is totally reliable, it is intuitive and has got an appropriate appearance, and they highlight the decision algorithm's effectiveness.

Nurturing wearable and mHealth technologies for self-care: Mindset, tool set and skill set 培养自我保健的可穿戴和移动健康技术:心态、工具集和技能集
Zilu Liang, Yukiko Nagata, Mario Alberto Chapa Martell, Takuichi Nishimura
This study aimed to understand whether and how wearable technologies and mHealth services could be nurtured for self-care at the individual-level. We launched a self-care online survey in 2015, and a total of 188 participants (66% female; mean age = 30 years) completed the survey. Following the survey, we also conducted a qualitative study with 12 Fitbit users. In both studies, we focused on understanding three prerequisite elements for behavior change: mindset, tool set and skill set. The results showed that most people had the mindset that self-care was important for preventing chronic diseases, and their top health concerns were sleep quality, body weight, mood, skin conditions and chronic fatigue. As for tool set, users acknowledge the potentially positive impact and efficacy of the technologies in facilitating self-care. However, current technologies have several usability issues such as low accuracy, low technology transparency, and limited feedback. As for skill set, two major obstacles were identified: difficulty in sustaining the usage of the technologies, and lacking domain knowledge and data analysis skills to gain insights from personal data. Different from existing studies which mainly focused on understanding the tool set, i.e., the technologies and services per se, this study produced new insights on the current landscape of people's mindset and skill set on adopting the technologies for health behavior change. We also summarized the opportunities and challenges to guide researchers in designing new wearable technologies and mHealth services for self-care.
本研究旨在了解可穿戴技术和移动医疗服务是否以及如何在个人层面上培养自我保健。我们在2015年发起了一项自我保健在线调查,共有188名参与者(66%为女性;平均年龄= 30岁)完成调查。在调查之后,我们还对12名Fitbit用户进行了定性研究。在这两项研究中,我们都专注于理解行为改变的三个先决因素:心态、工具集和技能集。结果显示,大多数人都认为自我保健对预防慢性疾病很重要,他们最关心的健康问题是睡眠质量、体重、情绪、皮肤状况和慢性疲劳。至于工具集,用户承认这些技术在促进自我保健方面的潜在积极影响和功效。然而,目前的技术存在一些可用性问题,如准确性低、技术透明度低和反馈有限。在技能方面,确定了两个主要障碍:难以维持技术的使用,以及缺乏从个人数据中获得见解的领域知识和数据分析技能。现有的研究主要侧重于了解工具集,即技术和服务本身,与此不同,本研究对人们在采用技术以改变健康行为方面的心态和技能的现状产生了新的见解。我们还总结了指导研究人员设计新的可穿戴技术和自我保健移动健康服务的机遇和挑战。

An attribute based access control scheme for secure sharing of electronic health records 用于安全共享电子健康记录的基于属性的访问控制方案
H. S. G. Pussewalage, V. Oleshchuk
Electronic health records (EHRs) play a vital role in modern health industry, allowing the possibility of flexible sharing of health information in the quest of provisioning advanced and efficient healthcare services for the users. Although sharing of EHRs has significant benefits, given that such records contain lot of sensitive information, secure sharing of EHRs is of paramount importance. Thus, there is a need for the realization of sophisticated access control mechanisms for secure sharing of EHRs, which has attracted significant interest from the research community. The most prominent access control schemes for sharing of EHRs found in literature are role based and such solutions have the drawback of requiring the users to be registered in the system. Therefore, we propose a secure attribute based EHR sharing scheme using selective disclosure of attributes, which can meet the security requirements of EHRs. The proposed model is policy based and the access decisions are made based on the possibility of a user for being able to provide a proof that the user possesses a set of attributes that satisfies the access policy referenced to the access requested resource. Furthermore, the proposed model is capable of granting access for registered users in the system as well as unregistered but legitimate users, paving the way towards realizing a secure and flexible EHR sharing scheme.
电子健康记录(EHRs)在现代医疗行业中发挥着至关重要的作用,它允许灵活地共享健康信息,从而为用户提供先进、高效的医疗服务。虽然共享电子病历有很大的好处,但鉴于这些记录包含大量敏感信息,安全共享电子病历至关重要。因此,有必要实现复杂的访问控制机制来安全共享电子病历,这已经引起了研究界的极大兴趣。文献中发现的用于共享电子病历的最突出的访问控制方案是基于角色的,这种解决方案的缺点是需要用户在系统中注册。因此,我们提出了一种基于安全属性的电子病历共享方案,该方案采用选择性的属性公开,能够满足电子病历的安全要求。所建议的模型是基于策略的,访问决策是基于用户能够提供证明的可能性来做出的,证明用户拥有一组属性,这些属性满足访问请求资源所引用的访问策略。此外,所建议的模型能够为系统中的注册用户以及未注册但合法的用户授予访问权限,为实现安全灵活的电子病历共享方案铺平了道路。

Assessing the relational database model for optimization of content discovery services in medical imaging repositories 评估用于优化医学影像存储库中内容发现服务的关系数据库模型
A. P. Alves, T. Godinho, C. Costa
Medical imaging has been an essential contributor to high-quality medical decisions. In the past few years, the production of medical imaging data has grown impressively, thanks to the increasing number of imaging centers and higher resolution modalities. Keeping high availability and acceptable performance in this scenario raises new challenges related to storage, discovery and distribution of imaging data. Nowadays Picture Archiving and Communication System (PACS) must optimize these processes to the limit to cope with Big Data usage scenarios. In this regard, this work explores novel technologies to improve the performance of query and retrieve services in medical imaging context, ensuring always the compatibility with Digital Imaging and Communications in Medicine (DICOM) standard. The focus is the optimization of querying services. Namely, we conducted several controlled experiments to determine the best database model to support these services. More precisely, we studied the performance of a traditional PACS archive, based on a relational database, against a more recent NoSQL database. We used large datasets with 7 million medical images that represent accurately a year of medical practice. The result of this work is a set of guidelines for the correct usage of analyzed databases in big data medical imaging scenarios, including the advantages and limitations of each model.
医学影像一直是高质量医疗决策的重要贡献者。在过去几年中,由于影像中心数量的增加和更高分辨率的模式,医学影像数据的产生有了令人印象深刻的增长。在这种情况下,保持高可用性和可接受的性能提出了与成像数据的存储、发现和分发相关的新挑战。如今,为了应对大数据的使用场景,PACS必须对这些流程进行最大限度的优化。在这方面,本工作探索了新的技术,以提高查询和检索服务在医学成像环境中的性能,确保始终与医学数字成像和通信(DICOM)标准兼容。重点是查询服务的优化。也就是说,我们进行了几个受控实验,以确定支持这些服务的最佳数据库模型。更准确地说,我们研究了基于关系数据库的传统PACS存档与较新的NoSQL数据库的性能。我们使用了包含700万张医学图像的大型数据集,这些图像准确地代表了一年的医疗实践。这项工作的结果是一套指导在大数据医学成像场景中正确使用分析数据库的指南,包括每种模型的优势和局限性。

A queue-size & channel quality based adaptation of the energy detection threshold in IEEE802.15.6 CSMA/CA IEEE802.15.6 CSMA/CA中基于队列大小和信道质量的能量检测阈值自适应
V. Marbukh, Martina Barbi, K. Sayrafian-Pour, M. Alasti
IEEE802.15.6 is a radio interface standard for wireless connectivity of wearable and implantable sensors and actuators located inside or in close proximity to the human body i.e., Body Area Network (BAN). Medical applications impose stringent requirements on BAN Quality of Service (QoS), including reliability and on-time availability of data. However, interference from other co-located BANs or other nearby devices sharing the same spectrum, e.g., due to BAN mobility, may cause unacceptable QoS degradation. This paper suggests that the impact of such QoS degradations can be minimized with a queue-size and channel quality based adaptation of the Energy Detection Threshold (EDT) at the transmitting nodes. Guided by known results for Q-CSMA/CA, we propose an adaptive EDT algorithm for use in the IEEE 802.15.6 BAN standard. Our preliminary simulation results demonstrate the performance gain of our algorithm compared to using a fixed EDT, and thus warrant future efforts in the adaptive EDT optimization as a mechanism to maintain QoS in various interference scenarios.
IEEE802.15.6是一种无线接口标准,用于位于人体内部或靠近人体的可穿戴和可植入传感器和执行器的无线连接,即人体区域网络(BAN)。医疗应用对BAN服务质量(QoS)提出了严格的要求,包括数据的可靠性和准时可用性。然而,来自其他同址BAN或共享同一频谱的其他附近设备的干扰,例如,由于BAN移动性,可能导致不可接受的QoS退化。本文提出可以通过在传输节点上基于能量检测阈值(EDT)的队列大小和信道质量调整来最小化这种QoS退化的影响。在Q-CSMA/CA已知结果的指导下,我们提出了一种用于IEEE 802.15.6 BAN标准的自适应EDT算法。我们的初步模拟结果表明,与使用固定EDT相比,我们的算法获得了性能增益,因此保证了自适应EDT优化作为在各种干扰情况下保持QoS的机制的未来努力。

Accessing image resolution and frame rate effects in radiology from a human and a machine point of view 从人和机器的角度访问放射学中的图像分辨率和帧率效果
Roland Ellerweg, P. Voigt, Tuomas Alhonnoro, M. Pollari, Phil Weir
In teleradiology a vast amount of medical images is sent from one location to another location. If the network infrastructure between the locations is poor, users experience long download times or, if a client application is used, application lags. To solve this issue lossless compression algorithms can be used as a first option. Unfortunately these algorithms can only compress the data to a certain degree which is most of the time not enough for the heavy requirements in teleradiology. As a second option the image data can be compressed lossily by reducing the image quality. This however can have an impact on the work of the user and also on image processing tools, when the images are post-processed. In this contribution we give a first impression of frame rate and resolution effects on the work of both, humans and machines, using the example of tumor diagnosis.
在远程放射学中,大量的医学图像从一个位置发送到另一个位置。如果位置之间的网络基础设施较差,则用户会经历较长的下载时间,或者如果使用客户端应用程序,则会出现应用程序滞后。为了解决这个问题,可以使用无损压缩算法作为首选。不幸的是,这些算法只能将数据压缩到一定程度,这在大多数情况下不足以满足远程放射学的高要求。作为第二种选择,可以通过降低图像质量对图像数据进行有损压缩。然而,当图像进行后处理时,这可能会对用户的工作以及图像处理工具产生影响。在这篇文章中,我们以肿瘤诊断为例,给出了帧率和分辨率对人类和机器工作的影响的第一印象。

In this contribution we give a first impression of frame rate and resolution effects on the work of both, humans and machines, using the example of tumor diagnosis.","PeriodicalId":167022,"journal":{"name":"2016 IEEE 18th International Conference on e-Health Networking, Applications and Services (Healthcom)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128846886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Survey on cybersecurity issues in wireless mesh networks based eHealthcare 基于无线网状网络的电子医疗安全问题调查
K. Saleem, Khan Zeb, A. Derhab, Haider Abbas, J. Al-Muhtadi, M. Orgun, A. Gawanmeh
Information and Communication Technologies (ICT) based applications for Ambient Assisted Living (AAL) help elderly or individual people living home alone. AAL system reliability is mostly based on the recent emerging class of network that is known as wireless mesh network (WiMesh). In WiMesh the information security is the most difficult problem to tackle because the medium is open to cyber-attacks. Moreover, when we talk about AAL where the complete personal information is digitized and stored, the need for implementation and maintenance of strict security measures is essential. In this article, we present a critical literature survey on communication security issues in e-health care environments. We highlight and explore the representative state of the art security prototypes for eHealthcare environments and also provide the details of their security characteristics. In addition, we discuss in detail the challenges and opportunities of these systems.
基于信息和通信技术(ICT)的环境辅助生活(AAL)应用可以帮助独居的老年人或个人。AAL系统的可靠性主要基于最近出现的一类网络,即无线网状网络(WiMesh)。在微信中,信息安全是最难解决的问题,因为该媒体容易受到网络攻击。此外,当我们谈到AAL时,完整的个人信息被数字化和存储,需要实施和维护严格的安全措施是必不可少的。在这篇文章中,我们提出了一个重要的文献调查通信安全问题在电子卫生保健环境。我们重点介绍并探讨了电子医疗保健环境中最先进的安全原型的代表性状态,并提供了其安全特征的详细信息。此外,我们还详细讨论了这些系统的挑战和机遇。
