The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.

One medium that has become very dominant in Nigeria’s communication system and could be used for the realization of the reforms agenda is the Home Video (Nollywood) industry in Nigeria. Nollywood gives us a peep into the culture, of Nigeria and Nigerians. The focus of this paper, therefore, is to critically examine the role of the home video in the effort to “fix” Nigeria. That Nollywood is getting a rightly deserved attention now makes it more important for us to examine how its films have fared in the dissemination and sustenance of the moral and ethical values that are so important for the success of these reforms. In doing this, the paper did a critical analysis of two home videos to analyse how they have portrayed some of the core virtues and vices that are characteristics of contemporary Nigeria. These include good neighbourliness, decency, equity, justice, fairness, materialism, corruption, violence, and voodoo, etc. It then offered some realistic suggestions towards achieving better moral and ethical values in our society.

In this paper, the authors demonstrate the use of software agents to extend the role of humans in a collaborative work process. The extended roles to agents provide a convenient means for humans to delegate mundane tasks to software agents. The framework employs the FIPA ACL communication protocol which implements communication between agents. An interface for each agent implements the communication between humans and agents. Such interface and the subsequent communication performed by agents and between agents contribute to the achievement of shared goals.

Success and failure in information technology (IT) projects depend on many factors. Based on the analysis of literature as well as the author’s research and experience, we can build a working hypothesis of a significant influence of the communication system on a final project outcome in the context of: • Communication between the project team and the outside world (users, suppliers, other project teams, etc.) • Communication within a project team In project management literature, communication occupies a significant position (Candle & Yeates, 2003; Maylor, 2003). Most research projects, however, are focused on the analysis of communication between the project team and the outside world while communication within the project team seems to take a second place. From the literature dealing with building effective project teams, research carried out by Mullins (2001) deserves a closer look. Mullins researched the key contradiction within a project team; he discovered that project leaders demand from their team members the willingness to compromise and subordinate while at the same time they promote individualism and want to foster creativity. Chaffe (2001), on the other hand, concluded that most people during their professional career lose both their creativity and individualism and prefer to conform to the existing standards. This is the very reason why some leaders prefer to build their teams from young people knowing that they lack experience. By doing that, they realize they increase the risk of not achieving their goals. Therefore, the IT leaders need to combine these conflicting trends and build the project team to ensure the overall success of the project. Adair (1999) indicates three criteria that need to be taken into consideration when evaluating potential team members: competence, motivation, and personal traits. The subject of this article is to prove the hypothesis that the communication system within the team significantly influences the its effectiveness. The key question that needs to be answered is: what conditions does the project leader need to create in order to maximize the positive and minimize the negative effects of teamwork? While at first glance this hypothesis might seem obvious, detailed analysis does not lead to decisive conclusions. While executing the project, teams could use different communication methods to both define the project tasks as well as evaluate results. The effectiveness of various communication methods can be very different; therefore, we want to prove the hypothesis that:

AbstractThis article, largely on the basis of in-depth research in archives in Lisbon, provides an account of the trading systems linking Delagoa Bay to its southern hinterland. Within this framework we argue that the role of the slave trade has been previously underestimated. There is evidence that the booming demand for slaves in Brazil and on the Mascarene Islands hit this region with force. The scale of that trade is difficult to establish because it was, by and large, illicit and so not systematically recorded. There are indications of a significant trade prior to 1823 and a substantial one after that date. There is also evidence that northern Nguni groups, including the Zulu kingdom, were deeply involved in this trading system. The main sources of captives, however, were militarily weak societies, like the Tembe, which lived closer to the Bay.
