Recommending video content for use in group-based reminiscence therapy
REMPAD is a semi-automated cloud-based system used to facilitate digital reminiscence therapy for patients with mild-to-moderate dementia, enacted in a group setting. REMPAD uses profiles for participants and groups to proactively recommend interactive video content from the Internet to match these profiles. In this chapter, we focus on the design of the system and then the system architecture, the system build, data curation, and usage scenarios. We also report a series of steps carried out as part of our user-centered design approach to system development, and a series of analyses on interaction logs which indicate various levels of effectiveness for different configurations of the recommendation algorithm we use. The results indicate high user satisfaction when using the system, and strong tendency towards repeated use in future

Multimedia broadcast and internet satellite system design and user trial results
The EU funded project, System for Advanced Multimedia Broadcast
and IT Services (SAMBITS), has created an enhanced and synchronised,
multimedia terminal for merging satellite broadcast and internet
telecommunication services in a way that efficiently combines the large
bandwidth of the broadcast channel and the interactivity of the internet.
This paper proposes a novel broadcast and internet service concept, illustrates
this concept with two service scenarios and develops a system architecture to
demonstrate the range of key benefits provided by these new technologies.
It then describes the interactive multimedia terminal that was used for
consuming this new service concept. Finally, the results of the user trials on the
terminal are presented and discussed
Service Platform for Converged Interactive Broadband Broadcast and Cellular Wireless
A converged broadcast and telecommunication
service platform is presented that is able to create, deliver, and
manage interactive, multimedia content and services for consumption
on three different terminal types. The motivations of
service providers for designing converged interactive multimedia
services, which are crafted for their individual requirements, are
investigated. The overall design of the system is presented with
particular emphasis placed on the operational features of each
of the sub-systems, the flows of media and metadata through the
sub-systems and the formats and protocols required for inter-communication
between them. The key features of tools required for
creating converged interactive multimedia content for a range of
different end-user terminal types are examined. Finally possible
enhancements to this system are discussed. This study is of particular
interest to those organizations currently conducting trials
and commercial launches of DVB-H services because it provides
them with an insight of the various additional functions required
in the service provisioning platforms to provide fully interactive
services to a range of different mobile terminal types

Distributed Learning System Design: A New Approach and an Agenda for Future Research
This article presents a theoretical framework designed to guide distributed learning design, with the goal of enhancing the effectiveness of distributed learning systems. The authors begin with a review of the extant research on distributed learning design, and themes embedded in this literature are extracted and discussed to identify critical gaps that should be addressed by future work in this area. A conceptual framework that integrates instructional objectives, targeted competencies, instructional design considerations, and technological features is then developed to address the most pressing gaps in current research and practice. The rationale and logic underlying this framework is explicated. The framework is designed to help guide trainers and instructional designers through critical stages of the distributed learning system design process. In addition, it is intended to help researchers identify critical issues that should serve as the focus of future research efforts. Recommendations and future research directions are presented and discussed

Faktor-faktor adaptasi logistik terbalik di sektor pembuatan
Dalam dunia yang mempunyai sumber yang terhad, proses pemulihan yang digunakan untuk bahan atau produk adalah kunci untuk menyokong populasi penduduk dalam meningkatkan penggunaan bahan. Pengurangan bahan buangan menjadi kebimbangan kepada industri negara yang berkonsepkan kitaran bahan kerana bahan buangan tersebut merupakan salah satu sumber yang menjana ekonomi industri tersebut. Proses terbalik melibatkan kos yang besar berbanding keuntungan. Perubahan dalam undang-undang untuk melindungi alam sekitar telah memberi kesan kepada ekonomi dan perkhidmatan. Kini, semakin banyak syarikat yang menggunakan proses aliran terbalik untuk pergerakan barangan dalam sistem logistik mereka. Industri pembuatan merupakan industri utama dalam penggunaan aktiviti logistik terbalik. Sistem logistik terbalik merupakan aktiviti yang membentuk proses yang berterusan untuk penggunaan semula produk sama ada digunakan semula ataupun untuk pelupusan. Pembuatan semula ditakrifkan sebagai salah satu kaedah pemulihan yang digunakan untuk produk yang rosak atau bahagian-bahagian yang boleh diperolehi semula dalam keadaan kualiti yang sama dengan produk baharu dan boleh dimasukkan ke dalam produk baharu dan akan dijual semula dalam pasaran sama dengan bahagian atau produk baharu. Aktiviti logistik terbalik sering dilaksanakan oleh pengeluar asal kerana bahan yang digunakan semula diperlukan untuk pengetahuan dalam pengeluaran tertentu. Eltayeb dan Zailani (2010) menyatakan kebanyakan pengeluar di Malaysia tidak berminat untuk menggunakan semula barangan kitar semula atau pelupusan disebabkan oleh perbelanjaan tambahan untuk mengendalikan aktiviti yang berkaitan dengan logistik terbalik

Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast
While sound and video may capture viewersâ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution
is this new type of interactive content, offered
in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop
multimedia authoring package Macromedia Director
into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals.
The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper.
In the following sections, an overview of the
operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services.
The next section examines a number of metadata
languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services
