» Electronical Health Record's Systems. Interoperability

» Simona Angela Apostol, Cosmin Câtu and Corina Vernic

Understanding the importance that the electronic medical health records system has, with its various structural types and grades, has led to the elaboration of a series of standards and quality control methods, meant to control its functioning. In time, the electronic health records system has evolved along with the medical data’s change of structure. Romania has not yet managed to fully clarify this concept, various definitions still being encountered, such as “Patient’s electronic chart”, “Electronic health file”. A slow change from functional interoperability (OSI level 6) to semantic interoperability (level 7) is being aimed at the moment. This current article will try to present the main electronic files models, from a functional interoperability system’s possibility to be created perspective.

» A fixpoint semantics for „memory cells” in synchronous dataflows

» Cătălin Dima

We study an iteration operation modeling the repeated behavior of syn-chronous dataflows in which all partial results are issued and also memorized for the next computation step. The definition is by means of a fixpoint equation. We prove some equational properties of iteration, comparing them to the ones of the Elgot iteration. We also prove a normal form theorem for dataflows and show that equality is decidable for canonical dataflows associated to freely generated algebraic theories.

» Teacher's Evaluation – a Component of Quality Assessment System

» Tiberiu Marius Karnyanszky, Laurenţiu Dan Lacrămă, Lucian Luca and Ioana Iacob

One of the most important activities to increase the importance and the responsibility of the higher education is the quality management, assessment and evaluation. Starting from 2006, a national mechanism was created in Romania and all the educational institutions have to apply a concrete algorithm to ensure the internal evaluation, the external evaluation and, the most important, to increase the quality of the educational process. This paper presents the implementation of the quality assessment in “Tibiscus” University of Timişoara, particularly at the Faculty of Computers and Applied Computer Science.

» Expert Software for the Determination of Juvenile People's Obesity

» Tiberiu Marius Karnyanszky, Corina Muşuroi and Carla Amira Karnyanszky

Keeping the health condition at the juvenile population is the concern of both the medical staff and the Physical education teachers. Considering the steady tendency of the growth of the number of the youth with excessive weight (overweighed or obese), the intervention to combat this phenomenon must be initiated in the early stage when this condition occurs. The screening method for evaluating the body weight presented in this study uses a calculus program through which, based on the input data (age, sex, weight the width of the skin fold), an evaluation regarding the each juvenile's weight and the body structure can be done. This program can be used in schools, high schools, universities, to signal the weight excess and to appreciate the intervention results for getting a normal weight.

» About Testing the Speed of Calculating the Shortest Route

» Tiberiu Marius Karnyanszky and Bogdan Şelariu

Applied into a various area of domains, the graph theory and its applications allow the determination of the shortest route. The common algorithm to solve this problem is Bellman-Kalaba, based on the matrix multiplying operation. If the graph is very large (e.g., the dimension of the associated incidence matrix is big), one of the main problems is to reduce the calculus time. This paper presents a testing method able to analyze if an acceleration of the Bellman-Kalaba is possible and able to determine the time efficiency.

» Hospital Acquired Infections: Advantages of a Computerized Surveillance

» Leonard Mada

Objective: To assess the advantages of a computerized surveillance system to detect Healthcare-Associated Infections (HAI).
Methods: All HAI reported to the Timis County branch of the Romanian National Health Insurance and the Public Health Authority during the year 2007 were collected and assessed for validity.
Data sources: International data were used to estimate the true HAI rate. Electronic records from the microbiology lab were used to predict the rate of HAI. Advanced models using DRG data and pharmacy order forms were not possible due to lack of this data.
Results: Only 10 out off 17 hospitals in Timis County reported the number of HAI. There were 529 cases during 2007, corresponding to <0.4 cases / 100 hospital admissions compared to 4.5 – 9.1 cases / 100 admissions in the medical literature. We estimated a true number of 6,000 HAI in Timis County during 2007. 29 MRSA and another 88 ceftazidime resistant strains were isolated during July 2007 in one of the hospitals. The total of 117 potential HAI comes close to the 150 HAI predicted for that hospital. Conclusions: Romanian hospitals report less than 10% of the HAI. Available electronic data can be used to estimate the true rate of HAI.

» Adaptation of Black-Box Software Components

» Rolf Andreas Rasenack

The globalization of the software market leads to crucial problems for software companies. More competition between software companies arises and leads to the force on companies to develop ever newer software products in ever shortened time interval. Therefore the time to market for software systems is shortened and obviously the product life cycle is shortened too. Thus software companies shortened the time interval for research and development. Due to the fact of competition between software companies software products have to develop low-priced and this leads to a smaller return on investment. A big challenge for software companies is the use of an effective research and development process to have these problems under control. A way to control these problems can be the reuse of existing software components and adapt those software components to new functionality or accommodate mismatched interfaces. Complete redevelopment of software products is more expensive and time consuming than to develop software components. The approach introduced here presents novel technique together with a supportive environment that enables developers to cope with the adaptability of black-box software components. A supportive environment will be designed that checks the compatibility of black-box software components with the assistance of their specifications. Generated adapter software components can take over the part of adaptation and advance the functionality. Besides, a pool of software components can be used to compose an application to satisfy customer needs. Certainly this pool of software components consists of black-box software components and adapter software components which can be connected on demand.

» On the Category of Partial Bijections

» Emil Schwab

Categories of partial functions have become increasingly important principally because of their applications in theoretical computer science. In this note we prove that the category of partial bijections between sets as an inverse-Baer*-category with closed projections and in which the idempotents split is an exact category. Finally the Noether isomorphism theorems are given for this exact category.

» Matrix Representations of the Thermo-dynamic Functions used for Studying the Burning of Gas Combustibles

» Amado George Ştefan, Silviu Marcel Dan and Gabriel Marin

The paper contains data regarding the processes that occur art normal pressure and the variations of enthalpy, entropy, molar isobar heat, isobar potential. The variations of enthalpy and molar isobar heat are useful in the calculation of the thermic balance-sheet, and those in connection with the isobar potential are useful for the calculation of the balances. The enthalpy and entropy are linear combinations of the temperature functions and, being taken as a basis for the calculation of isobar potential. The indicated proprieties for each component can be calculated, if we know the approximation function for the isobar molar heat and the known value of the propriety at a temperature. In order to find the, coefficients we consider known the values of the molar isobar heat at five values of absolute temperature, after which we apply the linear algebra method.
