Telemedicine Software Application
UNGUREANU, Ovidiu Costica,POPESCU, Marius-Constantin,CIOBANU, Daniela,UNGUREANU, Elena,SARLA, Calin Gabriel,CIOBANU, Alina-Elena,TODINCA, Paul International Journal of Computer ScienceNetwork S 2021 International journal of computer science and netw Vol.21 No.2
Currently, hospitals and medical practices have a large amount of unstructured information, gathered in time at each ward or practice by physicians in a wide range of medical branches. The data requires processing in order to be able to extract relevant information, which can be used to improve the medical system. It is useful for a physician to have access to a patient's entire medical history when he or she is in an emergency situation, as relevant information can be found about the patient's problems such as: allergies to various medications, personal history, or hereditary collateral conditions etc. If the information exists in a structured form, the detection of diseases based on specific symptoms is much easier, faster and with a higher degree of accuracy. Thus, physicians may investigate certain pathological profiles and conduct cohort clinical trials, including comparing the profile of a particular patient with other similar profiles that already have a confirmed diagnosis. Involving information technology in this field will change so the time which the physicians should spend in front of the computer into a much more beneficial one, providing them with the possibility for more interaction with the patient while listening to the patient's needs. The expert system, described in the paper, is an application for medical diagnostic of the most frequently met conditions, based on logical programming and on the theory of probabilities. The system rationale is a search item in the field basic knowledge on the condition. The web application described in the paper is implemented for the ward of pathological anatomy of a hospital in Romania. It aims to ease the healthcare staff's work, to create a connection of communication at one click between the necessary wards and to reduce the time lost with bureaucratic proceedings. The software (made in PHP programming language, by writing directly in the source code) is developed in order to ease the healthcare staff's activity, being created in a simpler and as elegant way as possible.

Objective: Mechanical alterations of the spine, which can cause chronic low back pain (LBP), are a frequent indication for spinal fusion. Studies have shown differences between genders in patients’ evaluations of health-related quality of life (HRQoL) after spinal procedures, but results have been conflicting, and some authors have suggested that cultural variation could explain these discrepancies. The objectives of this study were to determine the influence that gender plays on HRQoL, disability, and the correlation between the 2 in people undergoing spinal fusion for chronic LBP at a neurosurgical centre in Eastern Europe. Methods: Patients undergoing fusion surgery at a single centre for LBP with a duration of more than 3 months were included. They were evaluated using the Short Form Health Survey version-2.0 (SF-36v2) and Oswestry Low Back Pain Disability Index (ODI) questionnaire preoperatively and 1 year after the surgical procedure to identify differences between genders and to evaluate correlations between disability and quality of life. Results: We included 31 female and 30 male patients. The male patients had higher disability scores at the preoperative evaluation, but improved more than females in all domains of disability at the postoperative evaluation. HRQoL improved similarly in both genders. The ODI score showed a strong or moderate correlation with 6 of the domains of the SF-36 in males, but with only 3 domains in females. Surgery had a positive impact on the mental status of more men than women at risk of depression. Conclusion: The type of benefit that surgery offers seems to be influenced by gender. While HRQoL improved in both genders, disability decreased significantly more in male patients. Male patients also showed a closer correlation between HRQoL and disability. We conclude that men and women place different importance on specific aspects of their overall quality of life.

Numerical modelling and codification of imperfections for cold-formed steel members analysis
Viorel Ungureanu,Dan Dubina,Jacques Rondal 국제구조공학회 2005 Steel and Composite Structures, An International J Vol.5 No.6
Buckling and post-buckling of cold-formed steel members are rather difficult to predict due to material and geometrical non-linearity. However, numerical techniques have reached a level of maturity such that many are now successfully undertaking ultimate strength analysis of cold-formed steel members. In numerical non-linear analysis, both geometrical and material imperfections, have to be estimated and properly used. They must be codified in terms of shape and magnitude. The presented paper represents a state-of-art report, including relevant results obtained by the authors and collected from literature, on that problem.
