Abstract
Internet Banking has emerged as one of the most remarkable and profitable ecommerce applications over the last decade. The home banking is a service that allows new ways of interaction with customers, turning possible to overcome the barriers of distance between bank institutions and their clients. Despite the increasing importance of home banking, very few studies were made in the Portuguese context and, therefore, very little are known about the profile of users of this service particularly in some specific domains. This paper has the objective to show the results of our study considering the use of Internet Banking among Portuguese college students contextualized with other existing studies/publications and performing a critical analysis from the obtained results. We realized that the large majority of students use Internet Banking, consider the service safe, adopt it essentially for money movements and have a strong perception that bank institutions adopts anti-frauds mechanisms. Additionally, our study demonstrated that there is a strong association between the simultaneously use of home banking and MBNet services, and we realized that the user perception about the safety of Internet Banking increases with the use of these services. © Filipe Moreira, Pedro Rocha and Fernando Almeida, 2012.

Abstract
Unified Communications (UC) have the potential to dramatically simplify and improve enterprise communications, reducing costs and improving revenue opportunities. This paper proposes an architecture of three layers for a UC solution based on open source technologies and open standards. The Infrastructure layer is responsible for the physical IP infrastructure network, the Server Hardware and Operating System layer includes the back-end operating system and server services that can be used by the UC platform and the Business Applications layer integrates the UC with other external applications. Finally, the paper presents the major benefits of UC solutions, giving a special emphasis to the benefits derived for the use of a standards-based I P communications.

Abstract
Unified communications (UC) have the potential to dramatically simplify and improve enterprise communications, reducing costs and improving revenue opportunities. By integrating various forms of communications, such as voice, video, instant messaging, conferencing, presence and voicemail, individuals and groups can more effectively control and manage their inbound and outbound communications sessions. However, Large Enterprises (LE) and Small & Medium Enterprises (SMEs) have a diverse perspective look of UC and different needs. In this paper we will analyze the reasons that motivate the business leaders to introduce unified communications and we will study with detail the large enterprises and SMEs approach for the implementation of a unified communications solution. © 2009 IADIS.

Abstract
Unified Communications (UC) have the potential to dramatically simplify and improve enterprise communications, reducing costs and improving revenue opportunities. However, these benefits do not come without risks. The introduction of an IP-based UC solution brings an array of new vulnerabilities into the enterprise, exploited by a growing number of malicious programs. This paper presents the most common of risks faced by the major dominant technologies used in unified communications solutions and an approach to mitigate them.
