The study included 350 randomly selected neonates/infants discharged in the period April 2018–May 2019. CRE colonization was present in 88/350 (25.1%) of patients. Klebsiella pneumoniae producing KPC and OXA-48 carbapenemase were detected in 45 and 42 subjects, respectively, while NDM producing Escherichia coli was identified in one patient only. All OXA-48 strains harbored blaCTX-M-15, while both blaTEM and blaSHV were present in all but one KPC-producing strain. CRE isolates exhibited a multidrug resistance pattern with uniform fluoroquinolone resistance, universal susceptibility to colistin, and variable susceptibility to aminoglycosides. Administration of carbapenems was common (~50%) and it was strongly associated with colonization, as well as the combinational therapeutic regimens that included me...

Among the meningococci, serogroup B dominated (83%), followed by serogroup C (11.3%). High antigenic diversity was found, with fine type P1.5-1,10-4 being the most frequent. Moderate susceptibility to penicillin was common (55%). Within pneumococci, serotypes 19F, 14, 6B, 6A, 18C, 23F, 3, and 7F prevailed, while 19A was rare (3.6%). The coverages of PCV10 and PCV13 were 68% and 84%, respectively. Major sequence types were ST320, ST15, ST273, ST271, and ST81. Non-susceptibility to penicillin (66.7%), cefotaxime (37%), and macrolides (55%) was predominantly detected in vaccine-related serotypes. Among the 11 invasive H. influenzae isolates collected, there were six Hib, three non-type b, and two non-typeable strains (ntHi) that were...

In general, there are several methods, but the combined method simplifies data collecting and subsequent processing of results in comparison with other methods. Components determination was performed on the high precision levelling network in Serbia, by calculating undulation on each point, so as the azimuth and length of each side of the network starting from a reference point. The length of sides is in the range of 20 km to 300 km. A point approximately located in the middle of the network was chosen as a reference point. By applying least-squares method, the estimated values of the components were obtained. In addition to the statistical evaluation of the deflection of vertical components, the paper shows a comparison of the obtained values with the values from the global Geopotential models, which justifies using the combined method for networks of similar design.

Physical education classes are still the most organized mass system for engaging kids and young people in physical activities, through which certain influence on the organism is made. For a long sequence of years there are indications of certain changes in physical education classes as part of educational reforms in countries undergoing transition. Therefore there is possibility for innovation, improvement and further perfection of existing physical education classes syllabi in accordance with the needs of students and the society. Until now syllabi have been improved, changed and then applied without taking into account elements of physical education syllabi based on the quality analysis. In this paper comparative analysis of physical education syllabus for junior school age was performed for the following countries:...

Far from the center of those events, prurient shows of cheerleaders are a peripheral part of a sport event and contribute to the empowerment of the cult of the body in contemporary sport through its sexualization while the reason is surely a profit that goes to the organizers of those events. However, a different approach is possible and authors state an example of the basketball club Alba from Berlin, the management of which had decided, after 25 years, to stop the practice of cheerleading during the time-outs of the matches. The management stated the reason for the fact that the appearance of young attractive women cheerleaders is not convenient today because the club strives to promote women in sport as basketball players who could be a role model for the youth. A similar reason why they do not have cheerleaders could be found amongst some clubs from the National Footb...

The importance of physical activity is further accentuated in modern society’s living conditions. Technology is becoming increasingly present and children’s movement is brought to a minimum. Therefore, children are included in the system of sport, where competition occupies a central role. Parents frequently attend children’s training and competitions. The goal of this paper was to determine the influence of parents as part of the sports audience on children who practice sport. The authors wanted to ascertain the extent to which parents arrive at their child’s training and matches in order to provide support, in what measure they interfere with the coach’s work in training and matches and whether they punish Pannoniana, vol.

At the same time, they can be contagious to highly vulnerable individuals seeking health care. This study aims at estimating the seroprevalence of antibodies against SARS-CoV-2 and associated factors in HCW from a large referral hospital in Barcelona, Spain, one of the countries hardest hit by COVID-19 in the world.MethodsFrom 28 March to 9 April 2020, we recruited a random sample of 578 HCW from the human resources database of Hospital Clínic in Barcelona. We collected a nasopharyngeal swab for direct SARS-CoV-2 detection through real time reverse-transcriptase polymerase chain reaction (rRT-PCR), as well as blood for plasma antibody quantification. IgM, IgG and IgA antibodies to the receptor-binding domain of the spike protein were measured by Luminex. The cumulative prevalence of infection (past or current) was defined by a positive SARS-CoV-2 rRT-PCR ...

Production systems may employ conflicts in the scope of problem solving issues regarding research and development business processes. In that manner, conflicts may be perceived as positive events. This paper investigates the conflict styles in one production system which may be seen as one of the major activities in the conflict management process. The results suggests that the production systems should strive to direct conflicts into collaboration style so conflict resolution could provide benefits for the system.

E ects of proprioceptive trainings on the examined motor abilities were estimated by two explosive strength tests, three coordination tests and two agility tests. All respondents were tested before the application of the experimental treatment (pre-test) and a er its completion (post-test). To examine di erences in the achieved results between the initial and nal measurement for each group, t-test for dependent samples was used. To determine di erences between groups at the initial and nal measurement, t-test for independent samples was used. By comparing results from the initial and nal measurement, improvement in all tests for the observed abilities was perceived in the experimental group, while improvement in coordination tests and one agility test was noticed in the control group. Testing di erences in results between groups in the nal measurement showed that there are di ered only in agility tests, and in favour of the experimental group. Based on the obtained results, the conclusion was that the application of proprioceptive training in rhythmic gymnasts can contribute to improvement of agility, while in other observed abilities we cannot conclusively claim that improvement was the direct product of proprioceptive training.

The statements reflected the ethical theories of Aristotle (14 statements), Kant (14 statements) and Mill (16 statements). The hypothetical model of ethical theories was verified on a sample of 163 students at the Faculty of Sport and Physical Education in Belgrade (119 male students and 44 female students), attending all years of study (n1=22, n2=34, n3=36, n4=48, n5=23). We hypothesized that students would display greater maturity in terms of education and reaffirm their positions towards ethical issues in physical culture as they progressed in their studies, and also that the male and the female students had their specific moral outlooks on the reality of physical culture. When comparing the basic statistical indicators of students' responses to statements reflecting the ethical theories (Aristotle, Ka...

Prema jednoj sveobuhvatnoj sociološkoj definiciji, kultura se može shvatiti kao zaliha informacija i nagomilanog znanja, načina mišljenja, osjećanja i djelovanja koje određena društvena grupa prenosi na svoje potomke. Ovu definiciju možemo transponirati na područje zdravstvene i tjelesne kulture. Tako se zdravstvena kultura može definirati kao zaliha informacija i nagomilanog znanja, načina mišljenja, osjećanja i djelovanja vezanih za zdravlje i različite oblike zdravstvenog ponašanja. Slično, tjelesna kultura može se definirati kao zaliha informacija i nagomilanog znanja, načina mišljenja, osjećanja i djelovanja vezanih za oblast tjelesnog odgoja, rekreacije i sporta. Autori nastoje izdvojiti točke susreta zdravstvene i tjelesne kulture, te razmatraju tjelesnu kulturu i zdravstvenu kulturu kao vrijednosti. Najzad, autori navode rezultate empirijskog istraživanja o vrijednostima tjelesne kulture na uzorku studenata prve i pete godine studija Fakulteta sporta i fizičkog vaspitanja Univerziteta u Beogradu. Rezultati pokazuju da studenti visoko vrednuju zdravstvenu kulturu kao jednu od primarnih i specifičnih vrijednosti tjelesne kulture. Studenti pete godine studija s napredovanjem znanja u svim sferama studijskog programa proširuju svoj spoznajni vidik, pa tako i vrednovanje zdravstvene komponente, ne samo kao biološki dane u vrijednosnom sistemu tjelesne kulture nego i kao šire psihološke, sociološke, obrazovne i kulturološke komponente. Ključne riječi zdravstvena kultura, tjelesna kultura, zdravlje, tjelesnost, vrijednosti 1. Uvod. Kultura, zdravstvena kultura i tjelesna kultura U uvodnom dijelu rada razmotrit ćemo najznačajnija shvaćanja kulture. Riječ kultura dolazi od latinskog izraza cultura koji znači uzgajanje, oplemenjiva nje, obrađivanje, a kada se ovaj izraz primijeni na pojedinca, tada upućuje na humanizaciju ljudske prirode. U klasičnom smislu, ovaj pojam se najprije koristi u antropologiji u značenju cjelokupnog načina života jednog naroda. Antropolozi koji su izučavali preko tri stotine definicija pojma kulture, sma traju da je kategorija kulture višeznačan pojam: kultura se smatra sekundar nom prirodom, neizostavnim kontekstom ljudskog života, smatra se da se čovjek ne bi mogao razvijati bez kulture jer ona omogućava razvijanje sućin skih sposobnosti bez kojih čovjek ne bi bio čovjek itd. 1 Otuda se zbog višeznačnosti ove kategorije može govoriti o različitim aspektima kulture: ona

As the special payloads of the missiles, used projectiles are packaged as the metal liners, joined with explosive charges, to design explosive propulsion effect. Their final form and velocity during shaping depend on distributed temperatures in explosively driven plastic deformation process. Developed simulation model consider forming process without metal cover of explosive charge, in aim to discover liner's dynamical correlations of effective plastic strains and temperatures in the unconstrained detonation environment made by payload construction. The temperature fields of the liner's copper material are considered in time, as the consequence of strain/stress displacements driven by explosion environmental thermodynamically fields of pressures and temperatures. Achieved final velocities and mass loses as the expected explosively formed projectiles performances are estimated regarding their dynamical shaping and thermal gradients behavior vs. effective plastic strains. Performances and parameters are presented vs. process time, numerically simulated by the Autodyne software package.

The problem is very pronounced during periods of high solar activity, when various processes in ionosphere occur. This paper shows one way to model the ionosphere, which opens the possibility of calculating delays, which can then be applied as a correction during measurement processing. On the other hand, thanks to the knowledge of geodesy and global positioning system, the scientists involved in the ionosphere problem get a very powerful tool that can be used to form a two-or three-dimensional model of the ionosphere. One such two-dimensionаl model is presented in the paper.

However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study of waste heat recovering of the exhaust flue gas in a 1415 kWe cogeneration plant. This waste heat can be recovered by installing an economizer to heat the condensed and fresh water in thermal degasification unit and reduce steam use for maintaining the temperature of 105?C for oxygen removal. Design methodology of economizer is presented.

This paper describes the auditory parts of this system as well as interfaces to relevant parts of the complete system, including tracking and network streaming. In the demonstration, the Visitor is wearing headphones and a microphone. At the Destination, the two Locals are both wearing a microphone, while the Visitor is represented using a fixed position Totem with a single loudspeaker. The Position and movements of participants, particularly the head, are tracked and from this sound is rendered to include binaural cues so the visitor is able to move around in a limited space while perceiving Destination sound as "stationary". This setup includes 3 main tasks: Tracking coordinates are combined to calculate directions. This ...

Slično, tjelesna kultura može se definirati kao zaliha informacija i nagomilanog znanja, načina mišljenja, osjećanja i djelovanja vezanih za oblast tjelesnog odgoja, rekreacije i sporta. Autori nastoje izdvojiti točke susreta zdravstvene i tjelesne kulture, te razmatraju tjelesnu kulturu i zdravstvenu kulturu kao vrijednosti. Najzad, autori navode rezultate empirijskog istraživanja o vrijednostima tjelesne kulture na uzorku studenata prve i pete godine studija Fakulteta sporta i fizičkog vaspitanja Univerziteta u Beogradu. Rezultati pokazuju da studenti visoko vrednuju zdravstvenu kulturu kao jednu od primarnih i specifičnih vrijednosti tjelesne kulture. Studenti pete godine studija s napredovanjem znanja u svim sferama studijskog programa proširuju svoj spoznajni vidik, pa tako i vrednovanje zdravstvene komponente, ne samo kao biološki dane u vrijednosnom sistemu tjelesne kulture nego i kao šire psihološke, sociološke, obrazovne i kulturološke komponente. Ključne riječi zdravstvena kultura, tjelesna kultura, zdravlje, tjelesnost, vrijednosti 1. Uvod. Kultura, zdravstvena kultura i tjelesna kultura U uvodnom dijelu rada razmotrit ćemo najznačajnija shvaćanja kulture. Riječ kultura dolazi od latinskog izraza cultura koji znači uzgajanje, oplemenjiva nje, obrađivanje, a kada se ovaj izraz primijeni na pojedinca, tada upućuje na humanizaciju ljudske prirode. U klasičnom smislu, ovaj pojam se najprije koristi u antropologiji u značenju cjelokupnog načina života jednog naroda. Antropolozi koji su izučavali preko tri stotine definicija pojma kulture, sma traju da je kategorija kulture višeznačan pojam: kultura se smatra sekundar nom prirodom, neizostavnim kontekstom ljudskog života, smatra se da se čovjek ne bi mogao razvijati bez kulture jer ona omogućava razvijanje sućin skih sposobnosti bez kojih čovjek ne bi bio čovjek itd. 1 Otuda se zbog višeznačnosti ove kategorije može govoriti o različitim aspektima kulture: ona

As the special payloads of the missiles, used projectiles are packaged as the metal liners, joined with explosive charges, to design explosive propulsion effect. Their final form and velocity during shaping depend on distributed temperatures in explosively driven plastic deformation process. Developed simulation model consider forming process without metal cover of explosive charge, in aim to discover liner's dynamical correlations of effective plastic strains and temperatures in the unconstrained detonation environment made by payload construction. The temperature fields of the liner's copper material are considered in time, as the consequence of strain/stress displacements driven by explosion environmental thermodynamically fields of pressures and temperatures. Achieved final velocities and mass loses as the expected explosively formed projectiles performances are estimated regarding their dynamical shaping and thermal gradients behavior vs. effective plastic strains. Performances and parameters are presented vs. process time, numerically simulated by the Autodyne software package.

The problem is very pronounced during periods of high solar activity, when various processes in ionosphere occur. This paper shows one way to model the ionosphere, which opens the possibility of calculating delays, which can then be applied as a correction during measurement processing. On the other hand, thanks to the knowledge of geodesy and global positioning system, the scientists involved in the ionosphere problem get a very powerful tool that can be used to form a two-or three-dimensional model of the ionosphere. One such two-dimensionаl model is presented in the paper.

However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study of waste heat recovering of the exhaust flue gas in a 1415 kWe cogeneration plant. This waste heat can be recovered by installing an economizer to heat the condensed and fresh water in thermal degasification unit and reduce steam use for maintaining the temperature of 105?C for oxygen removal. Design methodology of economizer is presented.

This paper describes the auditory parts of this system as well as interfaces to relevant parts of the complete system, including tracking and network streaming. In the demonstration, the Visitor is wearing headphones and a microphone. At the Destination, the two Locals are both wearing a microphone, while the Visitor is represented using a fixed position Totem with a single loudspeaker. The Position and movements of participants, particularly the head, are tracked and from this sound is rendered to include binaural cues so the visitor is able to move around in a limited space while perceiving Destination sound as "stationary". This setup includes 3 main tasks: Tracking coordinates are combined to calculate directions. This ...
