The economical decision and the management of risk
The decision process as we know it today is influenced by many factors, especially by the important changes that appear in the economical environment. A good decision can be taken only after analyzing all available data and information, but, at the same time, after identifying and, if possible, reducing the influence of any possible risks that may appear. In this article, we refer to some aspects of the decision and the decision process and, in the second part, to elements regarding risk management.decision, risk management
Identifying Data Affected by Aberrant Errors. Applied Program
Statistical survey has become a very powerful tool for understanding reality and interpreting it and prediction. Nevertheless, even with the accepted margin for errors, a survey’s results may be inconcludent. This is mostly due to sample data quality. In this article, we refer to two tests to identify and eliminate aberrant errors, and at the end we present a program for applying these tests.Chauvenet, Young, program
A reality for any firm – the Information Technology
In a fast moving economy, no organization can expect good results without implementing new technologies. Computers, networks, software systems are a reality and denying it will eventually lead to a negative impact on the organizations’ results. In this, we refer to some aspects of information technology and the advantages and disadvantages that software systems can provide to a manager or management team and, in the end, to an organization.informational system, informatics system, DSS

Special Features In Turbulent Mixing. Comparison between Periodic and Non Periodic Case
After hundreds of years of stability study, the problems of flow kinematics are far from complete solving. A modern theory appears in this field: the mixing theory. Its mathematical methods and techniques developed the significant relation between turbulence and chaos. The turbulence is an important feature of dynamic systems with few freedom degrees, the so-called far from equilibrium systems. These are widespread between the models of excitable media.Studying a mixing for a flow implies the analysis of successive stretching and folding phenomena for its particles, the influence of parameters and initial conditions. In the previous works, the study of the 3D non-periodic models exhibited a quite complicated behavior, involving some significant events - the so-called rare events. The variation of parameters had a great influence on the length and surface deformations. The 2D (periodic) case is simpler, but significant events can also issue for irrational values of the length and surface versors, as was the situation in 3D case.The comparison between 2D and 3D case revealed interesting properties; therefore a modified 2D (periodic) model is tested. The numerical simulations were realized in MapleVI, for searching special mathematical events. Continuing this work both from analytical and numeric standpoint would relieve useful properties for the turbulent mixing. A proximal target is to test some special functions for the periodic model, and to study the behavior of the structures realized by the model
EUROPEAN LABOR MARKET EVOLUTION. PAST, PRESENT, FUTURE CHALLENGES
This paper aims to create a general image of the European Labor
Market from the end of WWII to present day, as well as to identify some major trends in Labor Market evolution in the following years. The focus is set on the direct link between labor market and economic development, and the evolution from the consumption society to the knowledge society today, and the global society of
tomorrow, and the influences on the structure of labor, from very skilled employees in industry to service professionals and the increased need of IT&C personal in the future

Coumadin ridge mass assessed on three-dimensional transoesophageal echocardiography
Transoesophageal echocardiography is often recommended in the evaluation of cryptogenic stroke, especially in those patients with no or few risk factors. We report the case of 66-year-old male with a history of multiple ischaemic strokes, admitted to our stroke unit following the discovery of multiple and diff use new ischaemic lesions on a cerebral magnetic resonance imaging. Transoesophageal echocardiography led to the discovery of a very small mass attached to the tissue fold between the left superior pulmonary vein and the left atrial appendage (often referred to as "coumadin ridge"). The three-dimensional acquisition allowed detailed characterization of this mass. No other source of emboli was detected. The mass was considered to be most likely a tumour and was probably the cause of the multiple strokes. Due to the already advanced neurological disease and the small dimensions of the mass surgery was considered inappropriate. The patient was initiated on oral anticoagulants. This case highlights the importance of three-dimensional ultrasound in the detection and evaluation of intracardiac masses.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
An atypical evolution of tako-tsubo cardiomyopathy
An 83-year-old woman with a possible history of myocardial infarction presented with acute chest pain and dyspnoea. The electrocardiogram showed no signs of acute coronary syndrome, but Q waves in the anteroseptal leads. The blood tests showed an important elevation of troponin T level. Emergency coronary angiography revealed normal epicardial arteries, but the left ventriculogram demonstrated anterior akinesis and ballooning with normal apical and basal function. An atypical takotsubo cardiomyopathy was suspected and the patient received beta blocker and ACE inhibitor treatment. Two days later the echocardiogram evolved to a classical pattern of apical ballooning with normalization on the follow-up examination 5 weeks from the acute episode. To our knowledge, this is the first case report describing an evolving pattern of wall motion abnormality from an anterior wall ballooning to an apical form.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
