Economy Politics and Sports Promotion

The development of games and sports has relations with the economy and politics of the country. It is evident from the world history that in every regime the ruler has tried to promote games and sports in the country, although their objectives might not be similar. There are instances of nations which have promoted physical culture, games and sports for making their nation physically fit as well as mentally alert, to prepare their defense personnel for tough jobs and even to reduce the national budget on medical expenditure of their citizens. The political set-up of the country shapes the fate of sports and games. The reality is that the economy of the country is now subject to politicization. It may not be wrong if it is said that prior to the promotion of sports and games, the destiny of the economy of the nation is decided by the politics of the country. The responsibility of formulation and implementation of economic policies, taking into consideration the needs of the country as well as the development of national economy matching with the rest of the world lies with National Government run by the Political leaders, Economists and Bureaucrats. In the promotion of games and sports, political system of a country plays a vitalrole

Regulatori struje aktivnih filtara snage za poboljšanje kvalitete snage: Tehnička analiza

Non-linear load deteriorates the quality of current waveforms at the point of common coupling of various consumers. Active power filter (APFs) is used to mitigate the most concern harmonic pollution in an electrical network. The controller part is the nucleus of an active power filter configuration. Active power filter performance is affected significantly by the selection of current control techniques. The active filter and its current control must have the capability to track sudden slope variations in the current reference to compensate the distorted current drawn by the voltage source inverter. Therefore, the choice and implementation of the current regulator is more important for the achievement of a satisfactory performance level. In this survey, technical reviews of various types of controllers covering a wide range have been presented. This work also reveals the advantages and disadvantages of the practiced control strategies. The effectiveness of the study will help the researchers to choose the proper control methods for various applicationsof active power filter.Nelinearni tereti pogoršavaju kvalitetu strujnih valova u točki u kojoj se spaja više potrošača.

Teaching Medical Microbiology With a Web-Based Course During the COVID-19 Pandemic: Retrospective Before-and-After Study

Background: The COVID-19 pandemic has imposed unprecedented hurdles on health care systems and medical faculties alike. Lecturers of practical courses at medical schools have been confronted with the challenge of transferring knowledge remotely. Objective: We sought to evaluate the effects of a web-based medical microbiology course on learning outcomes and student perceptions. Methods: During the summer term of 2020, medical students at Saarland University, Germany, participated in a web-based medical microbiology course. Teaching content comprised clinical scenarios, theoretical knowledge, and instructive videos on microbiological techniques. Test performance, failure rate, and student evaluations, which included open-response items, for the web-based course were compared to those of the on-site course from the summer term of 2019. Results: Student performance was comparable between both the online-only group and the on-site comparator for both the written exam (n=100 and n=131, respectively; average grade: mean 7.6, SD 1.7 vs mean 7.3, SD 1.8; P=.20) and the oral exam (n=86 and n=139, respectively; average grade: mean 33.6, SD 4.9 vs mean 33.4, SD 4.8; P=.78). Failure rate did not significantly differ between the online-only group and the comparator group (2/84, 2.4% vs 4/120, 3.3%). While lecturer expertise was rated similarly as high by students in both groups (mean 1.47, SD 0.62 vs mean 1.27, SD 0.55; P=.08), students who took the web-based course provided lower scores for interdisciplinarity (mean 1.7, SD 0.73 vs mean 2.53, SD 1.19; P<.001), opportunities for interaction (mean 1.46, SD 0.67 vs mean 2.91, SD 1.03; P<.001), and the extent to which the educational objectives were defined (mean 1.61, SD 0.76 vs mean 3.41, SD 0.95; P<.001). Main critiques formulated within the open-response items concerned organizational deficits. Conclusions: Web-based courses in medical microbiology are a feasible teaching option, especially in the setting of a pandemic, leading to similar test performances in comparison to on-site courses. The lack of interaction and the sustainability of acquired manual skills warrant further research

Detection of Bordetella trematum in a diabetic patient with a skin and soft tissue infection

A 38-year-old obese male with spastic diplegia and diabetes was hospitalized due to progressive ulcers of both lower extremities (Figure 1A). Computed tomography showed subcutaneous inflammation with suspected fascial involvement. The patient underwent surgical debridement, after which clindamycin was started empirically. Cultures from tissue samples grew gram-negative rods, identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) as Bordetella trematum (Figure 1B) and, in minor quantity, Myroides odoratimimus. Antimicrobial susceptibility testing of B. trematum was performed to obtain minimal inhibitory concentrations (in μg/mL; ampicillin ≤2; piperacillin ≤4; cefuroxime ≥64; ceftazidime 4; meropenem ≤0.25; moxifloxacin 2). Following the debridement, the patient’s condition improved substantially (Figure 1C), and he was discharged soon thereafter

Update on Coagulase-Negative Staphylococci—What the Clinician Should Know

Coagulase-negative staphylococci (CoNS) are among the most frequently recovered bacteria in routine clinical care. Their incidence has steadily increased over the past decades in parallel to the advancement in medicine, especially in regard to the utilization of foreign body devices. Many new species have been described within the past years, while clinical information to most of those species is still sparse. In addition, interspecies differences that render some species more virulent than others have to be taken into account. The distinct populations in which CoNS infections play a prominent role are preterm neonates, patients with implanted medical devices, immunodeficient patients, and those with other relevant comorbidities. Due to the property of CoNS to colonize the human skin, contamination of blood cultures or other samples occurs frequently. Hence, the main diagnostic hurdle is to correctly identify the cases in which CoNS are causative agents rather than contaminants. However, neither phenotypic nor genetic tools have been able to provide a satisfying solution to this problem. Another dilemma of CoNS in clinical practice pertains to their extensive antimicrobial resistance profile, especially in healthcare settings. Therefore, true infections caused by CoNS most often necessitate the use of second-line antimicrobial drugs
