ABSTRACT
This paper is held in the information technology services management environment, with a few ideas of information technology governance, and purposes to implement a hybrid model to manage the services of a database, based on the principles of information technology services management in a supplementary health operator. This approach utilizes fundamental nuances of services management guides, such as CMMI for Services, COBIT, ISO 20000, ITIL and MPS.BR for Services; it studies harmonically Availability and Continuity Management, as most part of the guides also do. This work has its importance because it keeps a good flow in the database and improves the agility of the systems in the accredited clinics in the health plan.

ABSTRACT
Ubiquitous and mobile context-aware computing is an essential component of the smart cities infrastructure. Widely available wireless networks, the maturity level of distributed computing and the increasing number of mobile devices have significantly influenced the human experience with computing. In the present paper, we discuss the need for a model that will be able to represent a formal structure of a context-aware system in a device. The core functionality of the model is expected to expose context-aware behaviour and support dynamic integration of mobile devices and context-aware behaviour. The major contribution of this work is to identify deficiencies of the existing model which is using the notions from sociology such as Role, Ownership and Responsibility.

ABSTRACT
Background: Progressive chronic kidney disease (CKD) failure and kidney diseases are increasing at an alarming rate all over the world. However, despite the remarkable advance in health technology, where it has become possible to successfully screen patients and predict kidney progression, a large portion of the world population is still unaware of their disease and risk exposure. Mobile Health (mHealth) solutions associated with health campaigns and programs proved to be an effective mean to enhance awareness and behaviour change at individual and social level.
Objective: The aim of this survey was to present the results of an environmental scan of what has been happening in the field of kidney disease prevention campaigns in recent years, with a focus on the use of mobile health as a tool to enhance the campaign's effects on targeting people and change their behaviour.
Methodology: It was conducted a systematic and comprehensive review, combining experimental studies with theoretical perspectives, to look for evidence regarding the evaluation of kidney disease prevention campaigns. The databases consulted for the present survey were: MEDLINE, PubMed, Google Scholar, PsycINFO, SAGE Journals Online, and Web of Science among other sources, for an analysis period from January 2000 to June 2016.
Results: Concerning the 14 analyzed examples with impact on kidney disease prevention campaign evaluation, two main campaigns were referred: The World Kidney Day (WKD) campaign, and the Kidney Early Evaluation Program (KEEP). The indicators used in this analisys were in most cases comparable regarding the campaign messages, objectives and interventions tools, although em both cases the use of mHealth or other technologies is residually comparing to other diseases prevention campaigns or programs.
Conclusions: This review pointed to the inexistence of behavioural change evidence as a target of the kidney disease prevention campaigns and their evaluation. General deficiencies concerning the use of technology to target and engage populations and lack of theory-based interventions, might have contributed for these results. This study highlights the need for reviewing the campaigns design and methodologies, redesigning strategies all over the campaign processes and the need of developing more tools and indicators, based on technology intervention for population's engagement on campaigns regarding kidney disease prevention.

ABSTRACT
E-commerce has been increasingly applied as it promotes economic growth by enabling online shops to compete within a global market scenario. There are critical success factors that permit to distinguish a good business on the Internet and this knowledge may allow reaching an important competitive advantage for business sustainability. As many disciplines are involved, when determining critical success factors, e-commerce requires an effective coordination and integration in a collaborative way. In e-commerce, as well as in any other ecosystem, the breaking down of some integrating elements may provoke a collapse on the whole system. The various stakeholders involved in a given business should, therefore, be involved and work together to achieve a high-quality product that fully satisfies the end customer's needs and wishes. To meet the above requirement, this paper proposes a multi-perspective critical success factors (MPCSF) model for online shopping.

ABSTRACT
A comparison study of the Web interaction evolution of a group of people with intellectual disabilities, when performing search tasks using the YouTube platform, is presented. For the effect, we compare results in two assessment moments (the second assessment moment was performed, within the 6 months after the first one).
We aimed at evaluating the evolution of their digital skills by comparing two assessment moments through the following usability variables: effectiveness, we register the rate of successful complete conclusion of Web search activities using the YouTube; efficiency, where it was register: time of task conclusion, number and type of difficulties found and errors made; satisfaction, the rate of acceptance and comfort when performing the tasks; and, autonomy indicators.
The results revealed that participants depicted more learning skills when performing the second assessment moment, which is indicated by the number of participants who were able to conclude the activities and it's also confirmed by the prominent results of the second assessment moment. When it comes to errors, they made more errors in the first assessment moment in general. While handling the input devices the participants had a better performance with the mouse than the keyboard however in the second assessment moment they improved their skills with the mouse and keyboard input device. However, we believed that the keyboard will never be a device that they can be autonomous with due to their reading/ writing difficulties, which itself represents a didactic challenge when it comes to the very presentation of appropriate methodologies and techniques that may help them overcome such problem. Overall, users with intellectual disabilities had a good experience with the YouTube interface because they were motivated and satisfied during the execution of the tasks, however they were not autonomy with the search option.

ABSTRACT
The Letrinhas information system contributes to the improvement of students' reading literacy combining the potential of mobile devices and the specific needs of students and teachers. This information system has emerged within the framework of a partnership established between the Instituto Politécnico de Tomar (IPT) and the Artur Gonçalves Cluster of Schools, in Torres Novas, Portugal.
After three years of the creation of the tool and its use in a real learning environment, the evaluation already carried out suggests a high degree of satisfaction on the part of teachers and students, as well as a very positive impact on improving the reading skills of the students involved in the project.
The latest version of Letrinhas has new features which lead to the specific challenges and needs of the teachers in the above-mentioned cluster of schools. Being so, in addition to the evaluation and improvement of reading skills, the new version provides features that enable the creation of educational scenarios promoting learning environments that enhance, not only the autonomy of students, but also their motivation.
