Communities and emerging semantics in semantic link network:discovery and learning

The World Wide Web provides plentiful contents for Web-based learning, but its hyperlink-based architecture connects Web resources for browsing freely rather than for effective learning. To support effective learning, an e-learning system should be able to discover and make use of the semantic communities and the emerging semantic relations in a dynamic complex network of learning resources. Previous graph-based community discovery approaches are limited in ability to discover semantic communities. This paper first suggests the Semantic Link Network (SLN), a loosely coupled semantic data model that can semantically link resources and derive out implicit semantic links according to a set of relational reasoning rules. By studying the intrinsic relationship between semantic communities and the semantic space of SLN, approaches to discovering reasoning-constraint, rule-constraint, and classification-constraint semantic communities are proposed. Further, the approaches, principles, and strategies for discovering emerging semantics in dynamic SLNs are studied. The basic laws of the semantic link network motion are revealed for the first time. An e-learning environment incorporating the proposed approaches, principles, and strategies to support effective discovery and learning is suggested.

iServe:a serious game for servitization

Servitization concerns the process of manufacturers shifting from a focus on producing and selling tangible goods to service-based business models. Factors that drive adoption of servitization are financial, strategic (competitive advantage) and marketing. However, uptake is slow and active efforts are being made to transfer knowledge about servitization to the manufacturing sector. This paper presents early results from the first test of a serious computer game which has the goal of educating managers about what advanced services are and how they fit in supply chains. Results suggest the role-play scenario tested is appropriate for an audience of largely non-expert gamers, and that the approach has the potential to instruct users about the role of services in the supply chain.

Kompetencia alapú, output orientált oktatás az ideális foglalkoztathatóság érdekében

A kutatási projektünk tanulmánysorozata a magyar gazdaság fejlődésének különböző gazdaságfejlesztési útjait vizsgálja 2020-ig, amelyben a foglalkoztathatóság kérdése kulcs szerepet kapott. Jelen tanulmányunkban arra a kutatási kérdésre keressük a választ, hogy milyen oktatási rendszerre lenne szüksége a magyar gazdaságnak ahhoz, hogy az említett 2020-ig megvalósítható különböző gazdaságfejlesztési utak számára, biztosítani tudja a megfelelő mennyiségű és minőségű emberi erőforrást. A kutatási kérdés megválaszolásának érdekében bemutattuk az oktatási rendszer értékteremtési logikáját, a kompetencia alapú, outputorientált oktatás koncepcióját, a jelenlegi oktatási rendszert és annak kialakulását a rendszerváltás óta, valamint a gazdaságfejlesztési utak megvalósulásához készített számításainkat. A magyar oktatási rendszer, annak stacioner fejlődése esetén nem lesz képes még a stacioner gazdaságfejlesztési út (átlagosan évi 1%-os GDP növekedés 2020-ig) emberi erőforrás szükségletének a biztosítására sem, nemhogy az ennél magasabb GDP növekedéssel járó ipari termelésen, vagy gazdasági szolgáltatásokon nyugvó különböző szcenáriók szükségletének biztosítására. A diplomások túlképzésének a hiedelme megalapozatlan, nem a diplomások mennyiségével van a probléma, mivel belőlük lesz a legnagyobb hiány a különböző gazdaságfejlesztési pályák alapján, hanem maximum azok minősége vethet fel kérdéseket. Ahhoz, hogy a gazdasági növekedésünk mögé az emberi erőforrás hazánkban megfelelő minőségű és mennyiségű legyen egy teljesen új koncepció szükséges az oktatással kapcsolatban. Be kell vezetni a kompetencia alapú, output orientált oktatási modellt, amelynek irányításában a munkaerőpiac szerepét jelentősen meg kell erősíteni, és az át-, és továbbképzések területének hangsúlyát jelentősen növelni kell. Mindezek hiányában, vagy az óhajtott gazdasági növekedés nem lesz megvalósítható, vagy fél milliós nagyságrendű képzett munkaerő importjára fog Magyarország rászorulni. ________ The working papers of our research project analyze the development paths of the Hungarian economy until 2020, where employability is one of the cornerstones of the research. The research question addressed in this paper is what kind of educational system does Hungary need if we want to provide the needed human resources for the mentioned development paths until 2020. To answer the research question we introduced the value creation logic of the educational system, the concept of competency based output oriented education, today’s educational system and its 20 years history and our calculations for the development paths. The Hungarian educational system with its stationer development will not be able to provide the needed human resources to the stationer economic development path (average 1% GDP growth until 2020), not to mention the more productive manufacturing based or service based scenarios. The belief of overeducation in higher education is unfounded, the graduates will have the highest shortage according to the development paths, however their quality could raise some questions. To provide the needed quality and quantity in human resources for the economic development we need to implement a radically new educational concept, the competency based output oriented educational system, where the control of labor market and the emphasis of retraining, development as well as life-long learning has to be significantly strengthened. Without these either the desired growth will not be achievable or we should import around half million trained worker to Hungary.

Autonomic hardware manager: uma arquitetura de hardware autonômico usando a solução de repositório ativo de componentes

This Thesis main objective is to implement a supporting architecture to Autonomic Hardware systems, capable of manage the hardware running in reconfigurable devices. The proposed architecture implements manipulation, generation and communication functionalities, using the Context Oriented Active Repository approach. The solution consists in a Hardware-Software based architecture called "Autonomic Hardware Manager (AHM)" that contains an Active Repository of Hardware Components. Using the repository the architecture will be able to manage the connected systems at run time allowing the implementation of autonomic features such as self-management, self-optimization, self-description and self-configuration. The proposed architecture also contains a meta-model that allows the representation of the Operating Context for hardware systems. This meta-model will be used as basis to the context sensing modules, that are needed in the Active Repository architecture. In order to demonstrate the proposed architecture functionalities, experiments were proposed and implemented in order to proof the Thesis hypothesis and achieved objectives. Three experiments were planned and implemented: the Hardware Reconfigurable Filter, that consists of an application that implements Digital Filters using reconfigurable hardware; the Autonomic Image Segmentation Filter, that shows the project and implementation of an image processing autonomic application; finally, the Autonomic Autopilot application that consist of an auto pilot to unmanned aerial vehicles. In this work, the applications architectures were organized in modules, according their functionalities. Some modules were implemented using HDL and synthesized in hardware. Other modules were implemented kept in software. After that, applications were integrated to the AHM to allow their adaptation to different Operating Context, making them autonomic.

RAGE Reusable Game Software Components and Their Integration into Serious Game Engines

This paper presents and validates a methodology for integrating reusable software components in diverse game engines. While conforming to the RAGE com-ponent-based architecture described elsewhere, the paper explains how the interac-tions and data exchange processes between a reusable software component and a game engine should be implemented for procuring seamless integration. To this end, a RAGE-compliant C# software component providing a difficulty adaptation routine was integrated with an exemplary strategic tile-based game “TileZero”. Implementa-tions in MonoGame, Unity and Xamarin, respectively, have demonstrated successful portability of the adaptation component. Also, portability across various delivery platforms (Windows desktop, iOS, Android, Windows Phone) was established. Thereby this study has established the validity of the RAGE architecture and its un-derlying interaction processes for the cross-platform and cross-game engine reuse of software components. The RAGE architecture thereby accommodates the large scale development and application of reusable software components for serious gaming.

Tissue engineering: technological advances to improve its applications in reconstructive surgery

Background. Tremendous advances in biomaterials science and nanotechnologies, together with thorough research on stem cells, have recently promoted an intriguing development of regenerative medicine/tissue engineering. The nanotechnology represents a wide interdisciplinary field that implies the manipulation of different materials at nanometer level to achieve the creation of constructs that mimic the nanoscale-based architecture of native tissues. Aim. The purpose of this article is to highlight the significant new knowledges regarding this matter. Emerging acquisitions. To widen the range of scaffold materials resort has been carried out to either recombinant DNA technology-generated materials, such as a collagen-like protein, or the incorporation of bioactive molecules, such as RDG (arginine-glycine-aspartic acid), into synthetic products. Both the bottom-up and the top-down fabrication approaches may be properly used to respectively obtain sopramolecular architectures or, instead, micro-/nanostructures to incorporate them within a preexisting complex scaffold construct. Computer-aided design/manufacturing (CAD/CAM) scaffold technique allows to achieve patient-tailored organs. Stem cells, because of their peculiar properties - ability to proliferate, self-renew and specific cell-lineage differentiate under appropriate conditions - represent an attractive source for intriguing tissue engineering/regenerative medicine applications. Future research activities. New developments in the realization of different organs tissue engineering will depend on further progress of both the science of nanoscale-based materials and the knowledge of stem cell biology. Moreover the in vivo tissue engineering appears to be the logical step of the current research.

HEALTHCARE INFORMATION SYSTEMS INTEGRATION USING SOA

The growing pressure to increase the quality of health services, as well as reducing costs, has caused healthcare organizations to increase the use of Information and Communication Technologies (ICT) through the development and adoption of Healthcare Information Systems (HIS). However, the need for exchange of information between HIS and between organizations has also increased, resulting in the problem of interoperability. This problem is considered complex, but the use of Service Oriented Architecture (SOA) appears as a good way to address this issue. This paper presents a systematic review, performed in order to find out how and in which contexts SOA is being used to ensure the interoperability of HIS.

Procedimentos de informação portuária electrónica

A integração de sistemas é uma necessidade cada vez mais necessária face à exigência e competitividade dos negócios. Uma forma de respondermos a estes factos é através da tecnologia, acompanhando-a e aprofundando-a. O presente documento apresenta uma proposta de solução tecnológica a estes factos. O caso que iremos abordar trata-se da necessidade de renovar o sistema de gestão portuária a nível nacional, garantido uma continuidade de negócio, assim como a implementação de novas funcionalidades que permitam a esta plataforma ser totalmente independente e integrável com outros sistemas e/ou adaptável a outras organizações no futuro. SOA, Service Oriented Architecture, foi a filosofia adoptada para garantir a facilitação do tráfego marítimo através da harmonização de processos e procedimentos entre os vários portos, fundamentalmente no referente à interconexão e interoperabilidade, e a partilha e troca electrónica de informação processual entre os vários membros da comunidade marítima e portuária. ABSTRACT; System integration is a necessity progressively more required due to the business demand and competitiveness. It is possible to respond to the latter facts with technology, by following it and developing it. This study proposes a technological solution for the abovementioned facts. The case to be addressed is the need to renovate the port management system in a nationwide scale, assuring simultaneously the continuity of the business and the implementation of new functionalities that allow for this platform to be utterly independent and applicable to other systems and/or adaptable to other organizations in the future. SOA, Service Oriented Architecture, was the theory adopted to guarantee the simplification of the maritime traffic, by harmonizing the processes and the procedures among the several ports, especially concerning the interconnection and interoperability, and the electronic sharing and exchange of information referent to processes amongst the numerous members of the maritime and port community.

Modelling and simulating retail management practices: a first approach

Multi-agent systems offer a new and exciting way of understanding the world of work. We apply agent-based modeling and simulation to investigate a set of problems in a retail context. Specifically, we are working to understand the relationship between people management practices on the shop-floor and retail performance. Despite the fact we are working within a relatively novel and complex domain, it is clear that using an agent-based approach offers great potential for improving organizational capabilities in the future. Our multi-disciplinary research team has worked closely with one of the UK’s top ten retailers to collect data and build an understanding of shop-floor operations and the key actors in a department (customers, staff, and managers). Based on this case study we have built and tested our first version of a retail branch agent-based simulation model where we have focused on how we can simulate the effects of people management practices on customer satisfaction and sales. In our experiments we have looked at employee development and cashier empowerment as two examples of shop floor management practices. In this paper we describe the underlying conceptual ideas and the features of our simulation model. We present a selection of experiments we have conducted in order to validate our simulation model and to show its potential for answering “what-if” questions in a retail context. We also introduce a novel performance measure which we have created to quantify customers’ satisfaction with service, based on their individual shopping experiences.

The roles of community pharmacists and other pharmacy staff:public perceptions

Introduction: The focus of the community pharmacist’s (CP’s) activities continues to move away from traditional dispensing activities towards the provision of health services. Current functions of CPs cover a combination of roles including prescription matters, counselling and service provision. These expanding roles, along with raised prescription volume, have increased CP workload. Therefore, it has become commonplace to delegate certain activities to other pharmacy staff (PS). This research aimed to examine public perceptions of CPs and other PS functions. Methodology: A self-completion postal questionnaire was sent to a random sample of 9769 members of the general public in England. Participants were asked to indicate which functions they believed CPs and other PS perform. Data were imported into SPSS 22 for analysis. Results: A response rate of 15.7% (n = 1537) was achieved. The roles most commonly attributed to CPs were monitoring prescription appropriateness (90.4%, n = 1390) and counselling patients on prescribed medicines (90.4%, n = 1389). The role most commonly attributed to other PS was sales transactions (92.4%, n = 1420). Similar numbers of responders agreed that the delivery of health services was the role of both CPs and other PS (58.9%, n = 906; 57.0%, n = 876). Conclusion: Despite a move towards more service based practice, the public still primarily associate the CP’s role with activities centred on dispensing. The provision of health services was seen to be equally carried out by CPs and other PS. As the CP’s service-based activities continue to develop, promotional activities may be required to ensure developments in CP functions are recognised by the public
