Healthcare providers have many complex and unique challenges. This paper proposes a systematic framework for conceptualizing the data-driven and mobile- and cloud-enabled smart healthcare systems. With adoption of smart healthcare systems, - more service oriented, more instrumented (from sensors to smart phones for monitoring health), interconnected (local and global epidemiological patterns), and intelligent (algorithms help recognize patterns and suggest appropriate responses from lots of data) - healthcare organizations can provide cost effective quality healthcare services with less IT set-up cost and reduced risk. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.35 http://doi.ieeecomputersociety.org/10.1109/MITP.2013.22 EVER INCREASING ENERGY COSTS, AND SAVING REQUIREMENTS, ESPECIALLY IN ENTERPRISE CONTEXTS, ARE PUSHING THE LIMITS OF ENTERPRISE RESOURCE PLANNING TO BETTER ACCOUNT ENERGY, WITH COMPONENT-LEVEL ASSET GRANULARITY. USING AN APPLICATION-ORIENTED APPROACH WE DISCUSS THE DIFFERENT ASPECTS INVOLVED IN DESIGNING ENERGY AWARE ERPS AND WE SHOW A PROTOTYPICAL OPEN SOURCE IMPLEMENTATION BASED ON THE DOG DOMOTIC GATEWAY AND THE ORATIO ERP. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.22 http://doi.ieeecomputersociety.org/10.1109/MITP.2013.21 We analyzed the software testing approach “Exploratory Testing (ET)” through a systematic review of literature to understand the consequences of ET as Technical debt. The evidence shows that ET is used as an alternative to any structured software testing approach to speed up the testing tasks and proved to be cost effective at the time of testing. Nevertheless ET also has many weaknesses that are not apparent at the time of testing but prompt up in later phases of system life cycle. Theses weaknesses incur increased rework and cost, and hence are considered to be the sources of TD. In addition we propose the possible solutions to embark upon these weaknesses that indeed help to reduce the testing technical debt of ET. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.21 http://doi.ieeecomputersociety.org/10.1109/MITP.2013.19 Software is increasingly developed in global projects, and such projects are challenged by distance, time zones and cultural differences. Knowledge management is central in order to ensure effective development of a product with the right features with the right level of quality. A central question is then what knowledge management approach to apply in global software development. This article draws on established research in software engineering, combined with three focus groups in two global companies to discuss what knowledge management schools are appropriate on a global level and what approaches are relevant for greenfield global projects. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.19 http://doi.ieeecomputersociety.org/10.1109/MITP.2013.4 Expediting the establishment and recognition of a disciplined profession of Enterprise Architecture requires the development of the elements of any generally recognized profession. In recent years, considerable study has been given rise to an inventory of those elements. Based on this research, the IEEE Computer Society developed a model of the elements of technical professions. In the past, formal professions have gradually evolved over time, arriving at maturity over many years (decades and longer in some cases). Our challenge has been to instantiate the Computer Society model to accelerate the maturation of the emerging profession of Enterprise Architecture. This is the Roadmap Journey. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.4 http://doi.ieeecomputersociety.org/10.1109/MITP.2013.1 From the data management point of view cloud computing provides full availability for users as they can read and write data anytime, anywhere. The acknowledgment time is almost stable and independent of associated users, size of the database or any added computing/communication constraints. Furthermore, users are freed for the burden of taking backups. If components fail, it is the responsibility of the service provider to replace them and make the data available using replicas in the meantime. This paper is a survey on 16 popular Cloud databases. http://doi.ieeecomputersociety.org/10.1109/MITP.2013.1 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.121 Social computing is an emerging field, which encompasses a diverse range of topics. A broad comprehension of major topics involved in social computing is important for both scholars and practitioners. The paper presents and analyzes the voluminous social computing related studies to date. The paper applies document co-citation analysis, pathfinder network, core document and Herfindahl-Hirschman index theories for the literature review. The results not only provide insight to this subject area, but also afford conduit for the future research in this discipline. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.121 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.118 Filtering based on blacklists is a major countermeasure against malicious websites. However, blacklists must be updated because malicious URLs tend to be short-lived and they may be partially mutated to avoid blacklisting. Due to these characteristics, it can be assumed that unknown malicious URLs exist in the neighborhood of known malicious URLs created by the same adversary. We propose an effective blacklist URL generation method, which discovers URLs in the neighborhood of a malicious URL by using a search engine. Those suspicious neighborhoods around malicious URLs require further investigation to determine their blacklisting candidacy. We experimentally evaluated the proposed generation method by using actual blacklisted URLs for both drive-by-download and click-download infection. The results showed that the proposed method can effectively improve identification of malicious URLs and maintenance of blacklist coverage. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.118 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.102 A software product is not used alone. It is integrated with supporting hardware and software. Together with developers, users, and other players, they form a software ecosystem. Accordingly, the success of a software product not only depends on the quality of the functions it can provide, but also depends on the success of its interdependent hardware, software, and other interacted players within its ecosystem. The software ecosystem studied so far ignored an important factor, the energy source. In this paper, market is considered as the energy source of a software ecosystem. It directly or indirectly affects all players within this ecosystem and finally determines the success of a software product. We call this market-driven software ecosystem. Our analysis of market-driven software ecosystem is performed on two communities: open source community and mobile computing community. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.102 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.90 This study proposes a new 2-in-1 medical monitoring system that enables medical devices to transmit vital sign data to an application host device on a network. The medical monitoring system is based on international standards, providing an interoperable platform on which personal healthcare systems exchange measurement data compliant with the data exchange protocol ISO/IEEE 11073-20601 and data device specifications of ISO/IEEE 11073-104zz series of standards via a Bluetooth HDP interface. The 2-in-1 medical monitoring system is the first dual-meter device providing both blood glucose and blood pressure measurements certified by International Organization, Continua Health Alliance. This medical monitoring system meets conformance requirements as well as basic interoperability requirements with other Continua certified devices. Using the 2-in-1 medical monitoring system, allows users to measure their vital signs, blood pressure, and blood glucose to be transmitted to any Continua application host device without an interoperability problem. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.90 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.88 Semi-structured processes are data-driven, human-centric, flexible processes whose execution between instances may vary dramatically. Due to their unpredictability and data-driven nature, it is becoming increasingly important to mine traces of events collected from these processes. Process mining techniques can help facilitate this goal. It may be daunting for novice users to determine which process mining algorithm to use when. In this article we compare five process mining algorithms available via ProM, introducing the reader to important capabilities of each algorithm. Readers can utilize the decision tree provided in this article to decide how suitable each mining algorithm is to a specific problem. Semi-structured processes, however, present challenges that are not addressed by these mining techniques. Therefore, in this article, we identify three key characteristics of semi-structured processes and the mining challenges they present, highlight a selection of emerging mining approaches that can address these challenges and discuss their applications. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.88 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.86 A large number of IT employees will soon be leaving the workforce due to retirement, which presents a serious problem for many IT departments. This problem is of greater concern in organizations and industries with complex business practices, legacy systems, or greater proportions of older workers. These organizations are vulnerable to a phenomenon called Y2Gray. This paper explores Y2Gray by explaining the problem, identifying organizations at risk, and presenting recommendations to address this problem. We share our findings from interviews with two firms that are coping with Y2Gray. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.86 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.68 Modern business applications have Operational Business Intelligence features that require processing analytical queries (OLAP) and business transactions (OLTP) together at the same time and on the same data. This results in mixed workloads (OLTP and OLAP on the same data) which are a big challenge for current database management systems. Cloud Computing fosters the development of data management systems that are optimized for specific application scenarios. We propose an architecture for Software-as-a-Service business applications that allows to process these mixed workloads with a special-purpose main-memory database system, while meeting strict service level objectives with stringent response time and throughput guarantees. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.68 http://doi.ieeecomputersociety.org/10.1109/MITP.2012.24 Interactions are described among some of the pillars of information assurance: authenticity, availability, confidentiality, integrity, and non-repudiation. For some pairs, efforts aligned with the goal of one pillar can frustrate efforts aligned with the other pillar. For example, availability may introduce conflicts with each confidentiality, integrity and authenticity, whereas confidentiality and integrity are largely complementary. http://doi.ieeecomputersociety.org/10.1109/MITP.2012.24 http://www.computer.org/portal/site/itpro/ IT Professional http://www.computer.org/portal/site/itpro/
