How to Improve the Web Information Space?
Miroslav Milinović, University Computing Centre, Croatia
Abstract
The Internet information space is extremely broad, complex and rich
in diverse contents, but, at the same time, inadequately organised.
Web information sources are characterised by contents distribution and
dynamics, therefore managing the Internet information space is not easy.
Since the Internet information space is based on the Web, this presentation
will deal exactly with web technologies and their practical implementation.
It will look into the extent to which the development of the omnipresent
Web and its accompanying technologies has contributed to the quality
of the information space, and the ways to use new technologies in day-to-day
work.

IT Armageddon: Seconds from Disaster
Ivica Ostojić, CISCO, Croatia
Abstract
The evolution of the world wide communications and the Internet began
in the 1960's, but their real expansion took place as late as the early
90's. The Internet became an indispensable tool, both in private and
in business life. We are not aware of the fact that all of our activities
are based upon specific data and information. Data in correlation with
other data constitute a piece of information. The Internet is an infinite
source of data and information. Therefore, whether we are ready or not,
the Internet is becoming a part of our lives.
However, nothing in the world is black or white. The Internet has two
sides. Today, security and privacy on the Internet represent a serious
problem, one which people do not take seriously enough. The fact that
computers are increasingly taking over more and more control over the
life processes of people does not make things any better. Network security
today is one of the biggest problems of the Internet, perhaps even the
greatest one. Every day we witness the newspaper articles and television
reports on security problems in the world of computers that have led
to financial losses, disclosure of classified information, etc.
Therefore, this presentation will show methods of computer systems attacks
and defence, with special emphasis on e-commerce, illustration of the
classic attacker profile, the condition in the Republic of Croatia,
and the methods of defence from such attacks.
Biography
Ivica Ostojić has been present in the computer security area for 10
years. His special line of work are security system controls, performed
by carrying out penetration tests, documentation audits according to
the internationally recognized standards such as ISO 17799, BS 7799-2,
SOX Section 404, COBIT, that is, the sphere of computer forensics.
For the last 5 years he has been a member of the IBM Croatia, covering
the CEEMAS (Central Eastern Europe - Middle East - Africa - Austria
- Switzerland) area as a Computer Security Consultant. Since the end
of June 2006, he has been working at the Cisco Systems as a Consulting
System Engineer for Computer Security, for the CEE area (Central Eastern
Europe).
Ivica Ostojić holds internationally recognized certificates on the computer
security, CISM and CISSP. He also has a Master's Degree on the thesis:
"Methods of Computer Systems Attacks and Defence", presented
in 2002.
GÉANT2: Latest developments and its importance for the Croatian research and education community
Dai Davies, DANTE, United Kingdom
Abstract
The world of research networking has developed dramatically in the last
20 years. Initially it was a field exclusively for network technician
specialists. In those days you had to have a sound knowledge of operating
systems and packet switching to get in the act.
Internet technology changed this picture significantly. For the first
time connectivity became available to ordinary users. In the absence
of any service a networking service that provides connectivity is bound
to be seen as innovative. The reality was, however, that performance
was always, and to some extent remains, a weakness.
The liberalisation of telecommunications markets in Europe, including Croatia, has enabled very large amounts of network capacity to be provided. This, to some extent, helps deal with performance issues. The reality however is that performance has today most users of research networks at the level where research networking was twenty years ago. Unless you are a network engineer or an operating systems specialist it is inaccessible.
GÉANT2 is part of an attempt to change this situation. It places much more emphasis on delivering end-to-end services to users and on providing users with tools to monitor what is provided on their behalf. The same challenges apply to all European countries and undoubtedly users of CARNET and the management of CARNET find themselves confronted with the same issues.
The main issue facing research networking in the next two years is to focus on service rather than technology. The presentation will consider the progress made in the context of GÉANT2 in terms of introducing services and the obstacles research networking needs to overcome in order to cater for an increasingly diverse and demanding user population.
Biography
Dai Davies is one of the founder General Managers of DANTE, the pan-European
research and education (R&E) network organisation that was set up
in July 1993. DANTE’s primary mission is to plan, build and manage pan-European
research and education networks on behalf of Europe’s National research
and Education Networks (NRENs). Over the last decade DANTE has implemented
various pioneering generations of such network, always focussing on
advanced communications services. As a result Dai has considerable experience
of the translation between technology and service in a broad range of
communications activities. GÉANT2 represents the latest generation of
pan-European R&E network. Building on the achievements of its predecessor
networks, GÉANT2 once again breaks new ground for global research networking
with its innovative hybrid network solution. GÉANT2 sets new standards
in terms of technology, network capacity, service portfolio and international
connectivity.
As research networking becomes a global activity, so DANTE becomes increasingly
involved in initiatives worldwide to build regional backbones and to
interconnect them to GÉANT2. DANTE is currently managing initiatives
focussed on the Mediterranean, Latin America and Asia-Pacifc regions
through the EUMEDCONNECT, ALICE and TEIN2 projects respectively.
Prior to DANTE, Dai was Director of the COSINE Project Management Unit
in Amsterdam. COSINE was a European project aimed at providing the academic
research community with telecommunications networking capabilities to
facilitate co-operative research.
In his earlier career Dai had worked for various European telecoms operators,
both in senior technical and commercial positions.
Dai holds degrees in Engineering and Computer Science from Cambridge
University.
ICT in education – lessons from the past, challanges for the future
Hamish Macleod, University of Edinburgh, United Kingdom
Abstract
Technologies not only provide us with new ways of doing things, but
also give us new things to do, and reasons to do things differently.
McLuhan observed that first we shape our technologies, and then our
technologies shape us. When applied in the field of education, technologies
may be used to support traditional practices, or to transform our practices
and provide us with new and engaging opportunities for exploratory and
experiential learning. Even the most radical and transformative applications
of educational technology however, need to be developed in continuity
with our long established, and continually emerging, understandings
of the nature of human learning and knowledge construction. There is
a danger that preoccupation with the potential of the new can seduce
us into educational practices simply because the technology makes them
possible, rather than because they are grounded in a good understanding
of human psychology. Powerful motivators for learning come from curiosity,
and from human relationship and social communication. Through the power
of large databases, high speed networks, and sophisticated simulations
of real and virtual worlds, technology can provide us with rich and
engaging environments for exploratory and collaborative learning. And
such systems are not exclusively the province of large educational institutions
or government departments, but are part of the everyday experience of
even the youngest schoolchildren. This paper will review some of the
ways in which these technologies can provide powerful and motivating
environments for learning.
Biography
Hamish Macleod is a Senior Lecturer at the University of Edinburgh in
Scotland, where he is a member of the University’s Centre for Teaching,
Learning and Assessment with a particular interest in the applications
of information and communication technologies (ICT) in education. He
has a background in psychology, and teaches courses on Understanding
Learning in the Online Environment, and Introduction to Digital Environments
for Learning at Masters level. His particular experience has been with
the uses of computer-mediated communications, and with the use of computer-based
games, role-play and simulations in support of teaching and learning.
A long standing area of research involvement has been with undergraduate
ICT literacy, and the ways in which the technologically mediated social
practices of young people are increasingly coming to interact with their
educational activities and aspirations.
