Capture and Reuse of Knowledge in ICT-based Decisional Environments

Health care practitioners continually confront with a wide range of challenges, seeking to making difficult diagnoses, avoiding errors, ensuring highest quality, maximizing efficacy and reducing costs. Information technology has the potential to reduce clinical errors and to im-prove the decision making in the clinical milieu. This paper presents a pilot development of a clinical decision support systems (CDSS) entitled MEDIS that was designed to incorporate knowledge from heterogeneous environments with the purpose of increasing the efficiency and the quality of the decision making process, and reducing costs based on advances of in-formation technologies, especially under the impact of the transition towards the mobile space. The system aims to capture and reuse knowledge in order to provide real-time access to clinical knowledge for a variety of users, including medical personnel, patients, teachers and students.Clinical Decision Support Systems, Knowledge Management, Knowledge Interoperability, Mobile Interface, Object-relational Mapping

The authors present a case study in the field of clinical decision support systems based on emerging technologies. They consider the changes generated by the upraising social technologies and the challenges brought by the interactive knowledge building within vast online communities.Knowledge Acquisition, CDDSS, 2D Barcodes, Mobile Interface

Premises and alternatives for dimensioning the enterprises bank credits

The paper deals with bank lending to economic agents from the premises and objectives of conducting this process by outlining the determinants of the extent to which banks can lend firms. In this regard, reference is made of financing and economic systems recognized in current theory and practice that have implications for the size of bank loans used by businesses. In particular, it cited the specific context of "economics of debt from banks, as outlined certain guidelines and limits that are to be taken into account by banks when determining the maximum loan that can be given.The central place is in the paper, sizing alternatives to bank loans by assessments made according to the specific determinants of work in concrete terms, the beneficiary companies. In particular, research work deepens the quantification of bank loans to assets necessary for the formation of economic assets. In this regard, consideration is sizing options (credit) promoted in banking practice, but it outlines the possibility of applying other solutions, especially one focused on the study of mathematical and statistical processing of the information provided electronically, usually through the levels certain synthetic indicators, which represent a factor / variable-issue compared to the factor / variable-effect, which is the maximum allowable credit

Effects of Using Borrowed Capital within the Companies’ Activities

The paper approaches some aspects regarding the use of the borrowed capital by the companies, in the light of the effects generated by it in relation to their own activity. The treatment of these effects starts from the premise that, beside the effect of increasing the total capital of which the company can dispose by obtaining loans, there are complementary effects such as increasing of costs, financial leverage and financial risk, which are analyzed in terms of the specific implications on the company’s activity. There are taken into consideration some particularities and their implications which come from the formation of the borrowed capital for the company, determined, in principal, by the use of the bank loans, respectively the use of the bond loans, inclusively in relation with the use of equity

In Memoriam: Prof. Ioan Dzitac - Editorial

In 2021, the International Journal for Computers, Communications and Control (IJCCC) entered its 16th year of existence. The first issue of the sixteenth volume of IJCCC was planned to be a special one dedicated to pay a tribute to the exceptional work and results of Lotfi Zadech, a great scientist born in 1921, who in uenced an immense number of the scholars all over the world. That special issue was thought and organized by Ioan Dzitac who wrote the Editorial. Several outstanding scholars were invited and accepted to publish in the intended special issue. It was Ioan Dzitac's last paper. Unfortunately, on 6th February, when the special issue was almost ready to be published, the heart of Ioan Dzitac suddenly stopped beating. Now, it is our sad duty of honour to propose to collaborators and readers of our journal a special issue meant to commemorate and pay a tribute to Ioan Dzitac, an honest and generous person, a talented and hardworking scientist and professor, an effective and empathic manager, a close and dear colleague and friend

Banking Services Based on High Information Technologies and their Implications

The paper approaches the most advanced information technologies, whose implementation gives shape to a new type of bank the bank of the future. Within the context, there are characterized the banking services, offered by this bank, such as home-banking, electronic banking, virtual banking and on-line banking from the point of view of their operation and of the performances, brought by using them, for the modern banking systems, including the Romanian one, presently and for thefuture

Collaborative Decision-Making: Concepts and Supporting Information and Communication Technology Tools and Systems

Collaboration means in substance that several entities such as humans, computers, robots, enterprises and so on jointly perform a certain task instead of working individually so that a better result could be obtained. Decision-making is a specific form of activity, commonly carried out by human agents, which is meant to eventually select a certain course of action which is expected to result in attaining a desired result. The chapter is meant to present a concise and balanced view of the basic concepts and main classes of supporting information and communication tools and systems regarding decision-making processes carried out by several collaborating human agents called participants. The reasons for collaboration are briefly explained followed by an exposure of collaboration application in the multi-participant decision-making settings. Having presented the classification of decision problems and decision-making units, the main phases of a specific multi-participant form of Herbert Simon’s decision process model are described followed by the presentation of two main forms of close and soft collaboration, namely consensus building and crowdsourcing, respectively. The need for technology support offered to collaborating participants is justified and two main classes of decision supporting systems, namely Decision support systems and the ever more largely used platforms, are addressed. A practical example of an open ended and evolving platform is presented. Open questions about the further role the information and communication tools in multi-participant decision-making processes are eventually formulated from two perspectives, digital humanism and dataism, respectively

ECONOMIC GROWTH AND IMPACT FACTORS IN COUNTRIES OF CENTRAL AND EASTERN EUROPE

This paper starts from the premise that the performance of the economies of different countries, respectively their economic growth, is sinthtically expressed by the GDP growth indicator, whose dynamics evolves under the impact of a variety of determining factors, including some of financial-monetary nature. Thus, there are highlighted specific causal linkages and influences of economic and financial factors represented by certain indicators (inflation, unemployment, exports as percentage of GDP, imports as percentage of GDP, domestic credit as percentage of GDP, non-performing loans rate) to GDP growth rate, by using econometric methods. Much of the paper is focused on on shaping an econometric model in which GDP growth rate is dependent variable and the other mentioned indicators are impact factors, respectively determinant variables. Along the mentioned determining factors, in our model is evaluated also the impact of the manifestation of the recent financial crisis, considering it as an additional determinant dummy variable. By processing the data for a group of countries of Central and Eastern Europe over the period 2000-2013, there result findings on the impact of each of the determining factors on the economic growth in the countries concerned and are formulated the appropriate assessments and conclusions

Implications on the Profitability of Banking Activity in the Context of the Current Global Financial Crisis

In this paper, the author outlines synthetically, first, landmarks of the manifestation of the global financial crisis effects with implications on the profitability of commercial banks, highlighting causal linkages which determine the return on assets (ROA) of the commercial banks. In this context it is deepened the research also in terms of the dynamics expressed by the evolution of banks’ ROA and of the correlations of the respective rate with some macro indicators (the changes in EUR/RON exchange rate, the unemployment rate, GDP variation etc.), by adapting and using an econometric model in which the changes in ROA is the dependent variable while the other indicators are determinant variables. The results obtained by processing the data corresponding to the variables included in this econometric model, including the change in non-performing loans volume, within the analysis aiming the situation in Romania in the period 2008-2013, basically highlight negative implications of the mutations occurring on the background of the current financial crisis manifestation, reflected in reducing the profitability of the banking activity

Audit for Information Systems Security

The information and communication technologies advances made available enormous and vast amounts of information. This availability generates also significant risks to computer systems, information and to the critical operations and infrastructures they support. In spite of significant advances in the information security area many information systems are still vulnerable to inside or outside attacks. The existence of an internal audit for information system security increases the probability of adopting adequate security measures and preventing these attacks or lowering the negative consequences. The paper presents an exploratory study on informatics audit for information systems security.Information System Risks, Audit, Security
