Introduction: Due to the declaration of a state of emergency in the country due to the pandemic COVID-19, the education system was changed to online teaching. The implementation of distance education has led to an increased sedentary lifestyle, decreased physical activity, and increased use of information technologies. The purpose of this study was to analyze the sedentary habits of female students and their physical health during a period of restricted physical activity with reference to online instruction.Methods: The research was conducted among the first to third grade students of Secondary School Konjic, 45 days after the implementation of online instruction. Students of general secondary school (N = 83), business school (N = 68), and medical school (N = 55) completed the questionnaire after their parents gave their consent.Results: The total number of students surveyed was 206, with students from all three schools studied participating in online classes for up to 4 hours. Medical school students spend more than 3 hours completing schoolwork, while students at the other two schools spend up to 2 hours. Statistically significant differences in non-use of information technology during free time exist among medical students (p = 0.00). Female medical students reported daily symptoms such as headaches, reactions to the visual organ (dry eye, redness, and tearing), and pain in the fist area (twitching, cramps, and tingling). Statistically significant differences in the occurrence of pain in the upper back and chest girdle occurred in students of business school (p = 0.00) and general high school (p = 0.00) compared to medical students.Conclusion: Medical students who use information technology the most reported headaches, pain in the fist area, and frequent reactions to the sense of sight (dry eye, lacrimation, and redness). Assuming inappropriate positions during prolonged use of technology may contribute to poor posture.

Najveći broj ispitanika bile su medicinske sestre (57%), prosječne dobi 36 godina života i 13 godina radnoga staža. Većina ispitanika pokazali su relativno dobro znanje o HIV-infekciji (73%) i pozitivne stavove prema HIV-pozitivnim osobama (80%). Koeficijent korelacije za zbirne vrijednosti znanja i stavova iznosio je 0,336, sa statističkim značajem 0,002. Zaključak: Da bi se poboljšala praksa, smanjila stigma i diskriminacija HIV-pozitivnih osoba u zdravstvenim ustanovama, potrebno je provoditi kontinuiranu edukaciju svih zaposlenika.

African Swine Fever virus (ASFV) is a large double-enveloped DNA virus of the Asfarviridae family that causes a lethal hemorrhagic disease in domestic pigs and wild boars. Since 2007, a highly virulent genotype II strain has emerged and spread in Europe and South-East Asia, where millions of animals succumbed to the disease. Field- and laboratory-attenuated strains of ASFV cause highly variable clinical disease severity and survival, and mechanisms remain unclear. We hypothesized that the immunological and hygienic status of pigs is a determinant of ASF disease course. Here we compared the immunological profile at baseline and in response to ASFV infection in specific pathogen-free (SPF) and farm-raised Large White domestic pigs. At steady state, SPF pigs showed lower white blood cell counts and a lower basal inflammatory and antiviral transcriptomic profile compared to farm pigs associated with profound differences in gut microbiome composition. After inoculation with a highly virulent ASFV genotype II strain (Armenia 2008), severe clinical signs, viremia and pro-inflammatory cytokines appeared sooner in SPF pigs, indicating a reduced capacity to control early virus replication. In contrast, during infection with an attenuated field isolate (Estonia 2014), SPF pigs presented a milder and shorter clinical disease with full recovery, whereas farm pigs presented severe protracted disease with 50% lethality. Interestingly, farm pigs showed higher production of inflammatory cytokines, whereas SPF pigs produced more anti-inflammatory IL-1ra early after infection, and presented a stronger expansion of leukocytes in the recovery phase. Altogether, our data indicate that the hygiene-dependent innate immune status has a double-edge sword impact on immune responses in ASF pathogenesis. While the higher baseline innate immune activity helps the host in reducing initial virus replication, it promotes immunopathological cytokine responses, and delays lymphocyte proliferation after infection with an attenuated strain. Such effects should be considered for live vaccine development and vigilance.

The paper presents a neuro-fuzzy system for evaluating and predicting the success of a construction company in public tenders. This model enables companies to operate sustainably by assessing their own position in the market. The model was based on data from a seven-year study, where data from the first six years were used to adjust the model, while data from the last year of the study were used for testing and validation. The neuro-fuzzy model was tuned using the Artificial Bee Colony algorithm.

Lung transplantation is a therapeutic option for the treatment of advanced lung disease. The risk of pulmonary infections is increased in lung transplant recipients. We report a case of a pulmonary coinfection with Mycobacterium tuberculosis and Nocardia species in a lung transplant recipient.

Aim of this paper was to examine the contribution of football experience and the self-assessment of tactical/technical skills and social competencies on the perceived self-efficacy in junior and senior football players. A total of 164 football players from Bosnia & Herzegovina have taken part in the research, 79 of which were professional senior players and 85 were professional U18 (junior) players. Three measuring instruments were used in the research: A questionnaire on general information, a self-assessment scale of self-efficacy for football players and a scale for estimating tactical/ technical and social competencies in football was used to gather data. Based on the results and the conducted analyses, it is indicative that the model that encompasses the length of football experience and a self-assessment of tactical/technical and social competencies in senior football players contributed around 8.5% to the total explanation of perceived self-efficacy. In senior players, the length of experience has a greater significance in perceived self-efficacy compared to the perceived success in performing football elements. The set model doesn’t have an equal contribution in junior players, where the model entirely contributed with 14.3% of the explanation of perceived self-efficacy, and the perceived success of performing football elements also has a statistically significant contribution. So, the model which encompasses football experience and the perceived success in performing football elements (tactical/technical and social competencies in football) is not equally predictive in junior and senior players.

Because for many companies, continuous operation and maintenance of custom software are crucial, they usually want to ensure that this continues even if the software licenser cannot operate in the future, for example, due to bankruptcy. The easiest way to overcome this for the licensee is to get a copy of the updated source code. Software developers are understandably reluctant to give a copy of their proprietary source code to the customer. The most significant asset of software developers is usually their source code, which can contain valuable trade secrets. One of the ways a software developer can deal with a client that requires access to the source code is to agree to store the source code using a triple escrow agreement. Under the escrow source code agreement, the developer provides a copy of the source code and documentation to a neutral party for safekeeping. The third party will hand over the source code to the buyer only after certain conditions defined by the contract have been met, such as the bankruptcy of software developers. That keeps the developer's source code confidential while, in theory, giving the user access to it if necessary. In this paper, we present the term software escrow contract.

Background Electronic consultations (eConsults) are an increasingly used form of telemedicine that allows a nonspecialist clinician to seek specialist advice remotely without direct patient-specialist communication. Surgical clinics may see benefits from such forms of communication but face challenges with the need for intervention planning. Objective We aimed to use the Quadruple Aim Framework to integrate published knowledge of surgical outpatient eConsults with regard to efficacy, safety, limitations, and evolving use in the era of COVID-19. Methods We systematically searched for relevant studies across four databases (Ovid MEDLINE, Embase, Scopus, and Web of Science) on November 4, 2021, with the following inclusion criteria: English language, published in the past 10 years, and data on the outcomes of outpatient surgical eConsults. Results A total of 363 studies were screened for eligibility, of which 33 (9.1%) were included. Most of the included studies were from the United States (23/33, 70%) and Canada (7/33, 21%), with a predominant multidisciplinary focus (9/33, 27%). Most were retrospective audits (16/33, 48%), with 15% (5/33) of the studies having a prospective component. Conclusions The surgical eConsult studies indicated a possible benefit for population health, promising safety results, enhanced patient and clinician experience, and cost savings compared with the traditional face-to-face surgical referral pathway. Their use appeared to be more favorable in some surgical subspecialties, and the overall efficacy was similar to that of medical subspecialties. Limited data on their long-term safety and use during the COVID-19 pandemic were identified, and this should be the focus of future research.

Multimedia streaming over the Internet (live and on demand) is the cornerstone of modern Internet carrying more than 60% of all traffic. With such high demand, delivering outstanding user experience is a crucial and challenging task. To evaluate user Quality of Experience (QoE) many researchers deploy subjective quality assessments where participants watch and rate videos artificially infused with various temporal and spatial impairments. To aid current efforts in bridging the gap between the mapping of objective video QoE metrics to user experience, we developed DashReStreamer, an open-source framework for re-creating adaptively streamed video in real networks. DashReStreamer utilises a log created by a HTTP adaptive streaming (HAS) algorithm run in an uncontrolled environment (i.e., wired or wireless networks), encoding visual changes and stall events in one video file. These videos are applicable for subjective QoE evaluation mimicking realistic network conditions. To supplement DashReStreamer, we re-create 234 realistic video clips, based on video logs collected from real mobile and wireless networks. In addition our dataset contains both video logs with all decisions made by the HAS algorithm and network bandwidth profile illustrating throughput distribution. We believe this dataset and framework will permit other researchers in their pursuit for the final frontier in understanding the impact of video QoE dynamics.
