For the last 14 years decision factors have been searching for the magic formula in restructuring the healthcare sector. Eventually, the government has come to appreciate the benefits of IT solutions. Our paper presents recent advances in wireless technologies and their impact on healthcare, in parallel with the results of a study aimed to acknowledge the presence of the medical community on Romanian WWW and to evaluate the degree of accessibility for the general population. We have documented Web sites promoting health services, discussion forums for patients, online medical advice, medical image teleprocessing, health education, health research and documentation, pharmaceutical products, e-procurement, health portals, medical links, hospitals and other health units present on the Web. Initial results have shown that if the current trend in price decreases for mobile communications continues and if the government is able to provide funding for the communication infrastructure needed for pervasive healthcare systems together with the appropriate regulations and standards, this can be a long-term viable solution of the healthcare crisis.

In the development of any DSS, validation and uncertainty analysis are critical steps. Environmental problems are not only complex and multi-factorial, but also carrying, in most cases, a large amount of uncertain information. Uncertainty management must therefore be incorporated in environmental DSS and the evaluation process is not complete without uncertainty analysis. Validation is also part of the support system's evaluation and is designating the process of establishing the usefulness and relevance for the decision-making model for the intended application. Different approaches for assessing model validity, validation techniques and the relation between validation, verification and evaluation, together with different types and sources of uncertainty in environmental DSS and methods of representing and managing uncertainty are reviewed.

Moisil received posthumously the IEEE Computer Pioneer Award for the development of polyvalent logic switching circuits, the Romanian School of Computing, and support of the first Romanian computers. Moisil, one of the greatest Romanian intellectuals, was first of all a gifted mathematician. His mentors were Bertrand Russell, Stefan Banach and Kazimierz Kuratowski, and the Romanian mathematicians Spiru Haret, Dimitrie Pompeiu and Gheorghe Ţiţeica, among others. He graduated mathematics at the University of Bucharest in 1926 and obtained the Ph.D. in 1929 with a thesis of applied mathematics "Analytical Mechanics of Continuous Systems". His first works were devoted to functional analysis applied in the mechanics of deformable media and also to abstract algebra. But where we will focus on mostly is his visionary attitude embedded into a special sense for new directions in mathematics and the encounter during his activity at the University of Iaşi, with the Polish school of logic, marking the beginning of the wonderful adventures in the field of multi-valued logic. My contribution is focused on emphasising the major milestones of the journey of the mathematician towards the magic world of computer science.

Large collections of heterogeneous data, from ancient manuscripts to sounds, videos and spatial data are now available in electronic format. Digital libraries are capturing human knowledge and distributing it over the web. The increasing volume of data in today digital repositories and library data warehouses has determined a wide use of computer-based sophisticated analysis techniques. Special operation of data mining can be performed in order to answer questions of librarians and researchers in information science. In 2003, S. Nicholson and J. Stanton introduced a new term -- bibliomining - for data mining library systems.

Today we are defining information retrieval as the interdisciplinary science of searching for documents, for information within documents and for documents' metadata in databases and on the World Wide Web. For many decades IR was concerned with finding the needed information from large collections of text documents. The explosive growth of the use of digital multimedia, from image and graphics to audio and video files over the Internet and wireless communications, or stored on DVDs and CD-ROMs, has determined the development of a specific sub-field of IR, i.e. multimedia information retrieval. In this lecture I will focus only on text retrieval methods. The retrieving unit is the document and documents from a collection are extracted to form the text data base. The documents are Web pages, if we are searching the Web. The retrieving process is simple but not at all trivial: a user is issuing a query; the ...

Daily use of computer is a habit among children, so we decided optimization cario-prevention in school children aged 6-12 using a software. We designed an interactive application as a "diary" in which the child answers questions like: have you brushed your teeth in the morning/evening/after eating sweets? have you had a tooth ache today? etc. Data is saved daily and the user profile is generating. The doctor is automatically notified by the application if the child tooth hurts. DMF-T index value for the study group was 2, the reason for dentist visit was pain (80.6% of case). The Pearson coefficient between the D component of DMF-T with the frequency of tooth brushing (-0,506), sweets eating (-0,595) and the doctor visits (-0,443) is statistically significantly (p=0.00). The software application "Dentist" by the child-parent-doctor feedback mechanism is modeling the child behavior for oral health. The data obtained can be used as statistical data.

Starting with Computer Aided Learning (CAL), Computer Aided Training and Instruction (CAT and CAI) and up to present e-Learning, the research main goals were to improve learning and teaching in schools, to adapt teaching and learning to individual needs through personalized software, and last but not least, to provide the necessary learning resources at a lower cost. With the same aims in mind, we have carried out several experiments in order to better understand how educational software has to be designed and developed to better answer teachers and students expectations, to enhanced e-learning usability. In our paper we are presenting some of the experiments concerning school children 6 to 12 years old. Children were introduced to a virtual environment - a library (the virtual image of the central university library) and their behaviour was observed. Children participating in the study were computer literate. We were interested in identifying key factors that can motivate children to read books from the library. The study started in 2009. Based on our observations the virtual library application was modified several times in order to obtain better answers to educational aims and a higher degree of satisfaction from the young user.

There are new treatments, new medical technologies that can answer to some of these challenges, but often access to them is prohibited by the costs associated. An old proverb, attributed to Erasmus of Rotterdam says that "Prevention is better than cure". In our paper we are presenting a health portal-PRO VITA-designed to support education for a healthy lifestyle of the citizens of the district of Sibiu. In designing the portal we had considered, from the medical point of view, the fact that primary prevention starts with reduction of risk factors. From the technical point of view we took advantage of the opportunities offered by Web 2.0 services and technologies (web-based communities, wikis, blogs, social networks, RSS, LPWS-lifetime personal Web space, podcasts, Second Life, etc.), combined with the multi-agent paradigm.

The “Lucian Blaga” University of Sibiu has one of the most advanced digital libraries of Romania. In order to enhance the quality of the library services we have designed an exploratory study aimed to asses the impact of the digital library on student learning behaviour. Students, from almost all faculties (medicine and pharmacy, engineering, sciences, history and philology, law etc), have been involved in the study. They have been asked to answer to a questionnaire about how they are using the digital library, what other sources of information they are using, if they are satisfied with the library services, if and how they have obtained the required bibliography. The information obtained from questionnaires was compared with data on students' interaction with the digital library and with their learning outc...

And among all technologies, information technology is the one that has a direct and constant influence on our lives. Our society is evolving around information technology, it is a "information society", and we are witnessing the emergence of a new culture - the digital culture. This new culture is our reality but also a "field of study that seeks to explore the cultural ramifications of digital technology, and how the alterations in the patterns of communication, information processing, and archiving resulting from the use of digital technology have influenced human behaviour". In this lecture I will first discuss the different faces of digital culture, from e-mails, chats and blogs to digital art and social networks. Secondly, I will try to enlighten the impact of the digital revolution on education, with special references to engineering education. My argument will be based on several case studies, especially co...

SysTerN has been developed using the framework of the TeleNurse ID-ENTITY Telematics for Health EU project as a support for the dissemination actions carried on by CCSSDM (Center for Health Computing Statistics and Medical Documentation of the Romanian Ministry of Health) for Romania and other Central Eastern European countries. Currently, the terminology system uses the alpha version of ICNP, but this version is going to be replaced by the beta version. SysTerN is designed primarily for Romanian users but an English version is also available for other partners from CEE countries.

Concerning the first issue, the authors propose a standard for the information literacy skills certification as an extension of the already existing computer literacy ECDL/ICDL standard. Such a combined standard can be included in the regular university curriculum, based on the experience of already successful implementation of the ECDL standard as a university course Introduction to Informatics. For the second issue which is a more philosophical one, the authors draw some parallel between Internet, as a source of information, and older radio and TV broadcasting technologies, concluding that there is a significant danger that each new and promising technology, after passing the challenging, difficult and inspiring pioneering phase, becomes boring and over-commercialized. There is a hope that awareness of such danger will help to avoid it.

All standard testing parameters can easily be adjusted so the system can be used for many different purposes. Importance of web-based applications is directly connected with the fact that clients' side is free of any additional software installation. Programming technique is more complicated, but final results are more robust and useful. There are enough free software tools to implement almost any such system. The advantages of open technologies are well known and the target platform can be Linux, as well as Windows. Using different algorithms we can achieve client-server communication with a relatively few web pages and JAVA applications. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for popularity of such applications. The system was tested and proved to be reliable and comfortable to use.

The model is part of a larger project-DANTE-Socio-Cultural Models implemented through multi-agent architecture for e-learning-that has as main objective the development of a model for the virtual education system, student centred, that facilitates the learning through collaboration as a form of social interaction. The model requires its own universe in which the human agents interact with the artificial ones (software agents). The project presumes the combination of the artificial intelligence (multi agent) system with elements of the socio-cultural theory of learning by collaboration and human actors.
