Modeling and implementation of system for evaluation of published research outputs

Cilj – Prvi cilj istraživanja je kreiranje modela podataka i implementacija informacionog sistema zasnovanog na modelu za potrebe vrednovanja publikovanih naučno-istraživačkih rezultata. Model bi bio primenjen u CRIS UNS informacionom sistemu, kao podrška sistemu vrednovanja. Drugi cilj istraživanja je utvrđivanje u kojoj meri i na koji način se može automatizovati proces evaluacije koji se zasniva na različitim pravilima i pravilnicima. Metodologija – Kako bi se definisalo proširenje CERIF modela neophodno je bilo identifikovati različite aspekte podataka koji su prisutni u evaluaciji naučno-istraživačkih publikacija. Stoga, zarad potreba istraživanja, odabrana su i analizirana su dokumenta koja predstavljaju različite nacionalne pravilnike, okvire i smernice za evaluaciju. Za modelovanje specifikacije arhitekture sistema za vrednovanje korišćeni su CASE alati koji su bazirani na objektno-orijentisanoj metodologiji (UML 2.0). Za implementaciju proširenja CERIF modela u CRIS UNS sistemu korišćena je Java platforma i tehnologije koji olakšavaju kreiranje veb aplikacija kao što su AJAX, RichFaces, JSF itd. Pored navedene opšte metodologije za razvoj softverskih sistema korišćeni su primeri dobre prakse u razvoju informacionih sistema. To se pre svega odnosi na principe korišćene u razvoju institucionalnih repozitorijuma, bibliotečkih informacionih sistema, informacionih sistema naučno-istraživačke delatnosti, CRIS sistema, sistema koji omogućuju evaluaciju podataka itd. Ekspertski sistem koji bi podržao automatizaciju procesa evaluacije po različitim pravilnicima odabran je na osnovu analize postojećih rešenja za sisteme bazirane na pravilima i pregleda naučne literature. Rezultati – Analizom nacionalnih pravilnika i smernica dobijen je skup podataka na osnovu kojeg je moguće evaluirati publikovane rezultate po odabranim pravilnicima. Razvijen je model podataka kojim se predstavljaju svi podaci koji učestvuju u procesu evaluacije i koji je kompatibilan sa CERIF modelom podataka. Predloženi model je moguće implementirati u CERIF kompatibilnim CRIS sistemima, što je potvrđeno implementacijom informacionog sistema za vrednovanje publikovanih naučno-istraživačkih rezultata u okviru CRIS UNS. Ekspertski sistem baziran na pravilima može biti iskorišćen za potrebe automatizacije procesa evaluacije, što je potvrđeno predstavom i implementacijom SRB pravilnika u Jess sistemu baziranom na pravilima. Praktična primena –Zaključci proizašli iz analize pravilnika (npr. poređenje sistema i definisanje metapodataka za vrednovanje) se mogu primeniti pri definisanju modela podataka za CERIF sisteme i za sisteme koji nisu CERIF orijentisani. Sistem za podršku vrednovanju publikovanih naučno-istraživačkih rezultata je implementiran kao deo CRIS UNS sistema koji se koristi na Univerzitetu u Novom Sadu čime je obezbeđeno vrednovanje publikovanih naučno-istraživačkih rezultata za različite potrebe (npr. promocije u naučna i istraživačka zvanja, dodele nagrada i materijalnih sredstava, finansiranje projekata, itd.), po različitim pravilnicima i komisijama. Vrednost – Dati su metapodaci na osnovu kojih se vrši vrednovanje publikovanih rezultat istraživanja po raznim nacionalnim pravilnicima i smernicama. Dat je model podataka i proširenje CERIF modela podataka kojim se podržava vrednovanje rezultata istraživanja u CRIS sistemima. Posebna prednost pomenutih modela je nezavisnost istih od implementacije sistema za vrednovanje rezultata istraživanja. Primena predloženog proširenje CERIF modela u CRIS sistemima praktično je pokazana u CRIS sistemu Univerziteta u Novom Sadu. Sistem za vrednovanje koji se bazira na proširenju CERIF modela pruža i potencijalnu interoperabilnost sa sistemima koji CERIF model podržavaju. Implementacijom informacionog sistema za vrednovanje, vrednovanje naučnih publikacija je postalo olakšano i transparentnije. Potvrda koncepata da se ekspertski sistemi bazirani na pravilima mogu koristiti za automatizaciju vrednovanja, otvara totalno novi okvir za implementaciju informacionih sistema za podršku vrednovanja postignutih rezultata istraživanja.Aim – The first aim of the research was creation of data model and implementation of information system based on the proposed model for the purpose of evaluation of published research outputs. The model is applied in CRIS information system to support the system for evaluation. The second objective was determination of the manner and extent in which the evaluation process that is based on different rules and different rulebooks could be automated. Methodology - In order to define the extension of the CERIF model, it was necessary to identify the various aspects of data which is relevant in evaluation of scientific research publications. Therefore, documents representing different national regulations, frameworks and guidelines for evaluations were selected and analyzed. For the modeling of the system architecture, CASE tools were used, which are based on object-oriented methodology (UML 2.0). To implement the extension of the CERIF model within the CRIS UNS system, JAVA platform and technologies that facilitate creation of web applications such as AXAJ and RichFaces were used. In addition to this general methodology for development of software systems, best practice examples from the information systems development are also used. This primary refers to the principles used in development of institutional repositories, library information systems, information systems of the scientific-research domain, CRIS systems, systems that enable evaluation of data, etc. The expert system that supports automation of the evaluation process by different rulebooks was selected based on analysis of the existing solutions for rule based systems and examination of scientific literature. Results - By analysis of the national rulebooks and guidelines, a pool of data was gathered, which served as a basis for evaluation of published results by any analyzed rulebook. A data model was developed, by which all data involved in the evaluation process can be represented. The proposed model is CERIF compatible. The proposed model can be implemented in CERIF compatible CRIS systems, which was confirmed by the implementation of an information system for evaluation of published scientific research results in CRIS UNS. An expert system based on rules can be used for the needs of automation of the evaluation process, which was confirmed by the presentation and implementation of the Serbian Rulebook by Jess. Practical application - The conclusions raised from the analysis of rulebooks (e.g. Comparison of systems and defining metadata for evaluation) can be applied in defining the data model for CERIF systems and for systems that are not CERIF oriented. The system for support of evaluation of published scientific research results was implemented as part of the CRIS UNS system used at the University of Novi Sad, thus providing evaluation of published scientific research results for different purposes (e.g. promotion in scientific and research titles, assignment of awards and material resources, financing of projects, etc.), according to different rulebooks and commissions. Value – Metadata is provided on which basis the evaluation of published research results by various national rulebooks and guidelines is conducted. A data model and an expansion of the CERIF data model that supports the evaluation of the research results within CRIS systems are given. A special advantage of these models is their independence of the implementation of the system for evaluation of research results. The application of the proposed extension of the CERIF model into CRIS systems practically is demonstrated in the CRIS system of the University of Novi Sad. The system that implements an expansion of the CERIF model provides a potential interoperability with systems that support CERIF model. After the implementation of the information system for evaluation, the evaluation of scientific publications becomes easier and more transparent. A confirmation of the concept that the expert systems based on rules can be used in automation of the evaluation process opens a whole new framework for implementation of information systems for evaluation

Rehabilitation Treatment After Anterior Cruciate Ligament Surgery with Isokinetic and Isotonic Exercises

Generalni cilj ovog istraņivanja je da se uporede uĉinci izokinetiĉkog i izotoniĉkog vjeņbanja na rezultate rehabilitacije pacijenata tri mjeseca nakon hirurńke rekonstrukcije prednjeg ukrńtenog ligamenta. Analiziran je uzorak od 180 ispitanika podijeljen u dva subuzorka u odnosu na vrstu rehabilitacionog tretmana koji je provoĊen. Ispitivanu grupu A-izokinetiĉku saĉinjavalo je 90 muńkih ispitanika, prosjeĉne starosti 28.54±4.44 godina. Kod njih je rehabilitacioni protokol bio zasnovan na izokinetiĉkom vjeņbanju natkoljenih mińića. Ispitivanu grupu B-izotoniĉku (klasiĉnu) saĉinjavalo je 90 muńkih ispitanika, prosjeĉne starosti 27.93±4.27 godina. Kod ovih ispitanika se u rehabilitacionom protokolu za jaĉanje natkoljene muskulature primjenjivao program vjeņbanja sa dodatnim otporom, tj. izotoniĉko vjeņbanje u trenaņnoj sali. Prije poĉetka rehabilitacionog tretmana uraĊen je inicijalni izokinetiĉki test pri ugaonoj brzini od 60°/s kod svih ispitanika. Nakon tri i ńest sedmica rehabilitacionog tretmana raĊeni su kontrolni testovi istim naĉinom i prateći iste parametre kao i na inicijalnom testu. Na osnovu vrijednosti analize MANOVA i analize DISKRIMINATIVNA, naĊeni su znaĉajno bolji rezultati izokinetiĉkih testova u ispitivanoj grupi A - izokinetiĉkoj u odnosu na ispitivanu grupu B - izotoniĉku. Razlika izmeĊu ispitivanih grupa je bila znaĉajnija na finalnom mjerenju nakon ńest sedmica rehabilitacionog tretmana u odnosu na kontrolno mjerenje nakon tri sedmice tetmana. Na osnovu dobijenih rezultata istraņivanja zakljuĉujemo da je izokinetiĉko vjeņbanje djelotvornije po pitanju rehabilitacije natkoljenih mińića nakon rekonstrukcije prednjeg ukrńtenog ligamenta.General aim of this study is to compare the effects of isokinetic and isotonic exercise on the rehabilitation results in patients three months after surgical reconstruction of the anterior cruciate ligament. A sample of 180 subjects was analyzed, divided into two subsamples in relation to the type of rehabilitation treatment that was performed. The examined group A-isokinetic, consisted of 90 male subjects, at the average age of 28.54±4.44. Their rehabilitation protocol was based on isokinetic exercise of the upper leg muscles. The examined group B-isotonic (classical), consisted of 90 male subjects, at average age of 27.93±4.27. In the case of these subjects, an exercise program with additional resistance was applied in the rehabilitation protocol for strengthening the lower leg muscles, i.e. isotonic exercise in the gym. Before the start of the rehabilitation treatment, an initial isokinetic test was performed at an angular velocity of 60°/s in all subjects. After three and six weeks of rehabilitation treatment, control tests were performed in the same way and the same parameters were followed as in the initial test. Based on the values of MANOVA analysis and DISCRIMINATIVE analysis, significantly better results of isokinetic tests were found in the examined group A – isokinetic, compared to the examined group B –isotonic. The difference between the examined groups was more significant at the final measurement after six weeks of rehabilitation treatment compared to the control measurement after three weeks of testing. Based on the results of the research, we conclude that isokinetic exercise is more effective in terms of rehabilitation of the lower leg muscles after the reconstruction of the anterior cruciate ligament

RESULTADOS CLÍNICOS DA REDUÇÃO DO DÉFICIT DE TORQUE EM EXTENSORES E FLEXORES DO JOELHO APÓS A RECONSTRUÇÃO DO LIGAMENTO CRUZADO ANTERIOR

In this prospective study, we presented the effect of isokinetic training on the clinical outcome of rehabilitation in relation to the reduction of the torque deficit in thigh muscles (DEF) after anterior cruciate ligament (LCA) reconstruction. The prospective study followed 144 subjects, 72 women and 72 men, with a mean age of 28.20 ± 4.52, four months after anterior cruciate ligament reconstruction with a hamstring graft. Subjects were divided into two groups according to the type of rehabilitation treatment they underwent. Subjects of the isokinetic group (72 subjects, 36 males and 36 females), underwent kinesitherapy according to the isokinetic exercise protocol which consisted of a one-day isokinetic training lasting for thirty minutes, five times a week for six weeks. Subjects of the classical group (72 subjects, 36 males and 36 females) underwent kinesitherapy based on standard isotonic exercises to increase muscle strength, i.e. exercises with weights and in the gym. The difference in the outcome of rehabilitation was objectified by a concentric-concentric isokinetic test at an angular velocity of 60 °/s before the start, after three weeks and after six weeks of rehabilitation. The monitoring parameters were: torque deficit of the injured leg knee extensor in relation to the uninjured leg (EXDEF) -% and torque deficit of the knee flexor of the injured leg in relation to the uninjured leg (FLDEF) -%. Neste estudo prospectivo, apresentamos o efeito do treinamento isocinético no resultado clínico da reabilitação em relação à redução do déficit de torque nos músculos da coxa (DEF) após a reconstrução do ligamento cruzado anterior (LCA). O estudo prospectivo acompanhou 144 indivíduos, 72 mulheres e 72 homens, com média de idade de 28,20 ± 4,52, quatro meses após a reconstrução do ligamento cruzado anterior com enxerto de isquiotibiais. Os indivíduos foram divididos em dois grupos de acordo com o tipo de tratamento de reabilitação que realizaram. Os sujeitos do grupo isocinético (72 sujeitos, 36 homens e 36 mulheres), foram submetidos à cinesioterapia de acordo com o protocolo de exercícios isocinéticos que consistia em um dia de treinamento isocinético com duração de trinta minutos, cinco vezes por semana, durante seis semanas. Os sujeitos do grupo clássico (72 sujeitos, 36 homens e 36 mulheres) foram submetidos à cinesioterapia baseada em exercícios isotônicos padrão para aumentar a força muscular, ou seja, exercícios com pesos e na academia. A diferença no resultado da reabilitação foi objetivada por um teste isocinético concêntrico-concêntrico com velocidade angular de 60 ° / s antes do início, após três semanas e após seis semanas de reabilitação. Os parâmetros de monitoramento foram: déficit de torque do extensor do joelho da perna lesada em relação à perna não lesada (EXDEF) -% e déficit de torque do flexor do joelho da perna lesada em relação à perna não lesada (FLDEF) -%

DIAGNOSTIC OF SPINAL COLUMN MOBILITY USING SCHOBER’S TEST FOR LUMBAL SYNDROME BY APPLICATION OF PHYSICAL THERAPY AND SPORT RECREATION

The research was conducted on the sample of 90 male and female subjects with chronic lumbar syndrome, aged between 20 and 50, of which 45 men and 45 women who were divided in three groups, 30 subjects per each group, formed on the basis of exercises done by the subjects during and upon the rehabilitation (III groups). The longitudinal and time bound research was executed (8 months). The research was conducted in the Department V “Banja Slatina”, in the Institute for Physical Medicine and Rehabilitation “Dr Miroslav Zotović” in Banja Luka, including three Fitness centres in Banja Luka. The goal of the research was to compare results of testing of subjects who continued to engage in sport recreation after termination of a rehabilitation process in the Institution for Physical Medicine and Rehabilitation - IPMR “Dr Miroslav Zotović” in Banja Luka (by means of usual physical procedures) and the results of those subjects who did not continue kinesitherapy, nor sport-recreational activities. For the statistical analysis in the SPSS program ANOVA was used, especially Post Hoc Test – Tukey HSD. The results showed that during the eight-month research there was a statistically significant improvement of the observed parameters (Schober index), but with the application of programmed physiotherapy with recreation (gr. II) the best results were achieved, as well as more stable remission, which could be explained by biological effects of the programmed physiotherapy together with sport recreation.  Article visualizations

Successful treatment of cardiogenic shock by stenting of the left main coronary artery in acute myocardial infarction

Introduction. Patients with non-ST elevation acute coronary syndromes (NSTE-ACS) are sometimes severely hemodynamicly compromised. Urgent coronary angiography should be performed in these patients in percutaneous coronary intervention (PCI) centers according to the ESC NSTE-ACS guidelines to determine suitabilty for percutaneous or surgical revascularization. Case report. We reported a 62-year-old male with chest pain admitted to the Coronary Care Unit. ST segment depression of 2 mm in leads I, L and V4-6 was revealed at electrocardiogram. After following 6 hours the patient had chest pain and signs of cardiogenic shock despite of the therapy. Chest x-ray showed pulmonary edema. Echocardiographic examination showed dyskinetic medium and apical segments of septum. The patient underwent coronary angiography immediately which revealed 75% stenosis of the left main coronary artery with thrombus. The use of a GPIIb/III inhibitor-tirofiban and stent implantation resulted in TIMI III flow. After that the patient had no chest pain and acute heart failure subsided in the following days Echocardiography done at the fourth day from PCI showed only hypokinesis medium and apical segment of septum. The patient was discharged at day 11 from admission in a stable condition. Conclusion. Stenting of left main coronary artery stenosis in patients with cardiogenic shock and non- ST segment elevation acute coronary syndromes may be a life saving procedure

The safety of enoxaparine use in elderly with acute myocardial infarction

Background/Aim. Enoxaparin (ENOX), the lowmolecular- weight heparin, used in acute myocardial infarction (AMI) could lead to hemorrhage. The aim of this study was to determine whether bleeding was more often in AMI patients older than 65 or 75 years who receive ENOX or unfractionated heparin (UFH). Methods. Among the patients with AMI hospitalized during three successive months receiving ENOX or UFH, three group of parameters were investigated: demographic, ischemic and bleeding TIMI criteria. Results. Among 85 hospitalized patients with signs of AIM, there were 35 (41.2%) old 65 years or less, 32 (38.5) old 66-75 years and 18 (21.2%) older than 75 years. In AMI elderly patients, according to the received ENOX/UFH: ischemic complication (18.2 vs. 21.4%) were insignificantly lower and the number of lethal outcomes (18,2 vs. 17,8%) were insignificantly more often in ENOX group; represented only by one patient (age beyond 75 years), major and non-major bleeding events occurred only in UFH group. Conclusion. The ENOX usage in AMI in patients older than 65 years did not show any significant difference in efficacy and bleeding rate comparing to UFH

Prolonged Treatment of Disseminated Echinococcosis – a Case Report

Cistična ehinokokoza (CE), koju uzrokuje E. granulosus, zoonotska je bolest koja se pojavljuje na gotovo svim kontinentima, a endemična je za područje Mediterana. Bolest se najčešće prezentira afekcijom jednog organa i solitarnom cistom, a kod manjeg broja bolesnika radi se o diseminiranoj bolesti koja pogađa višestruke organe. U ovom je radu prezentirana mlada žena s diseminiranom ehinokokozom kod koje su hidatidne ciste verificirane u jetrima, slezeni, plućima, bubrezima i perikardu. Zbog specifičnosti oblika bolesti, dobi bolesnice te zbog čestih relapsa bolesti nakon završetka terapije, liječena je albendazolom kroz duži vremenski period. Želimo prezentirati nešto drugačiji modus liječenja ehinokokokze koji je rezultirao povoljnom regresijom i kontrolom bolesti.Cystic echinococcosis (CE), which is caused by E. granulosus, is a zoonotic disease present in almost every continent and endemic for the Mediterranean. The disease is principally presented with the involvement of a single organ and mainly with solitary cyst but in the smaller number of patients it can be a case of disseminated disease affecting multiple organs. In this report we present a young woman with disseminated echinococcosis with multiple hydatid cysts verified in liver, spleen, lungs, kidneys and pericard. Due to the specific form of disease, patient`s age and common relapses after the end of therapy, the patient was treated with albendazole for a prolonged period of time. We would like to present a somewhat different approach to the treatment of echinococcosis which resulted in regression and better control of the disease

Isokinetic quadriceps physiotherapy after knee surgery: a retrospective study

IntroductionQuadriceps weakness after knee surgery is the most common consequence that can have different consequences not only for the knee itself but also for the locomotor system in general. This study aimed to compare the results of isokinetic and isotonic exercise on torque restoration quadriceps on knee surgery.MethodsA sample of 180 subjects was analyzed and divided into two subsamples according to the type of rehabilitation protocol that was implemented. The examined group A-isokinetic consisted of 90 male subjects aged 28.54 ± 4.44 years, with a rehabilitation protocol based on the isokinetic exercise of the quadriceps. The examined group B-isotonic also consisted of 90 male subjects aged 27.93 ± 4.27 years, with a rehabilitation protocol for strengthening the quadriceps that applied an exercise program with additional resistance, i.e., isotonic exercise in the gym. Before the start of the rehabilitation treatment, an initial isokinetic test was performed at an angular speed of 60 °/s in all subjects. After 3 and 6 weeks of rehabilitation treatment, the control tests were performed in the same way as in the initial test.ResultsBased on the values of MANOVA analysis and discriminative analysis, significantly better results of isokinetic tests were found in the examined group A-isokinetic compared with those in the examined group B-isotonic. At the final measurement of group A, 83 respondents (92.2%) were placed in the “biggest” class out of the 90 respondents.ConclusionBased on the obtained research results, we conclude that isokinetic exercise is more effective in terms of physiotherapy of quadriceps hypotrophy after knee surgery
