Opis:
Utilization of drones is going to become predominated in cellular networks as aerial base stations in order to temporary cover areas where stationary base stations cannot serve the users. Detecting optimal location and efficient number of drone-Base Stations (DBSs) are the targets we tackle in this paper. Toward this goal, we first model the problem using mixed integer non-linear programming. The output of the proposed method is the number and the optimal location of DBSs in a two-dimension area, and the object is to maximize the number of covered users. In the second step, since the proposed method is not solvable using conventional methods, we use a proposed method to solve the optimization problem. Simulation results illustrate that the proposed method has achieved its goals.

Opis:
Introduction Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated with neck pain. Since head, cervical and thoracic postures and their relation with neck pain has not been studied in Iranian office employees, the purpose of this study was to investigate the relationship between some work-related and individual factors, such as poor posture, with neck pain in the office employees. Material and methods It was a cross-sectional correlation study carried out to explore the relationship between neck pain and sagittal postures of cervical and thoracic spine among office employees in forward looking position and also in a working position. Forty-six subjects without neck pain and 55 with neck pain were examined using a photographic method. Thoracic and cervical postures were measured using the high thoracic (HT) and craniovertebral (CV) angles, respectively. Results High thoracic and CV angles were positively correlated with the presence of neck pain only in working position (p < 0.05). In forward looking position, there was no statistically significant difference between the 2 groups (p > 0.05). Conclusions Our findings have revealed that office employees had a defective posture while working and that the improper posture was more severe in the office employees who suffered from the neck pain.

Opis:
Composting is commonly used for waste management and the evaluation of its quality is important for successful application. Seed germination test is commonly adopted due to its capacity to examine the toxicity level of compost. The seed test is usually evaluated on the final product and the results can vary with the different methods and the type of seed utilized. In this study, the evolution of seed germination tests during the composting process of municipal waste (MSW) mixed with poultry manure (PM) of two species tomato and sugar beet was examined. The impact of compost water extracts on seed germination and plant primary root growth for each sampling was reported. The chemical parametrs were evaluated on the final product. Results show that mixture C1 with a higher amount of municipal waste gave less compost yield than mixture C2. After 35 days of composting, the compost was phytotoxic for tomato and sugar beet seeds. The seeds of the two cultures reacted differently to the same compost. The compost could stimulate sugar beet germination at days 110, 140, 180, 212 and 252. Seed germination of sugar beet was increased and delayed by one day by the compost stabilized and mature as compared with the control.

Opis:
At the beginning of 2020, the world faced a new and unexpected challenge. Such a harmful situation has a potential to increase tensions in societies and create citizens’ distrust in their own governments and the European Union. In relation to these observations, the main hypothesis assumes that citizens’ trust in the Union decreased during the pandemic, compared to previous periods. Thus, the aim of the study is to identify the dynamics of trust in the EU in the member states. The research’s object is the citizens of the EU member states and the focus on dynamics in the levels of trust in 2016–2020, measured based on selected indicators. The data for analysis comes from the Eurobarometer. Statistical methods (frequencies and cross tables) and comparative approach are used for the analysis. On the macrolevel, it seemed that European leaders could do better, especially in the initial stages of the COVID-19 pandemic. However, the results of the Eurobarometer survey performed in the summer of 2020 show that average trust in the Union did not decreased. Тhe data shows that there is a variety across the countries, which was not presented in the current study. Thus, a further examination focused on the context in each of the countries is required, namely policies and measures stringency.
Na początku 2020 roku świat zetknął się z nowym i niespodziewanym wyzwaniem. Tak niesprzyjająca sytuacja ma potencjał zwiększenia napięć wśród społeczeństw i budowania sytuacji braku zaufania obywateli wobec własnych rządów i Unii Europejskiej. W odniesieniu do tych obserwacji główna hipoteza badawcza to założenie, że podczas pandemii zmniejszyło się zaufanie obywateli wobec państw członkowskich Unii Europejskiej w stosunku do lat poprzednich. W związku z tym celem badania jest identyfikacja dynamiki zmiany zaufania wobec Unii Europejskiej wśród jej państw członkowskich. Przedmiotem badania są obywatele Unii Europejskiej oraz skupienie na dynamice poziomu zaufania w latach 2016–2020 badane na podstawie wybranych wskaźników. Wykorzystane dane pochodzą z systemu Eurobarometr. Na potrzeby analizy posłużono się metodą analizy statystycznej (częstości i tablic krzyżowych) oraz porównawczej. Wydaje się, że na makropoziomie decydenci europejscy mogli sobie poradzić lepiej, zwłaszcza na wstępnych etapach wybuchu pandemii COVID-19. Wyniki ankiety przeprowadzonej przez Eurobarometr latem 2020 roku pokazują, że sytuacja różni się między państwami, czego jednak nie zaprezentowano w niniejszym badaniu. Z tego powodu potrzeba dalszych analiz skupionych na kontekście każdego państwa, tj. polityk szczegółowych i poziomu restrykcyjności wykorzystanych środków.

Water deficit is one of the major environmental issues affecting biodiversity. Drought-related works are conducted to explore the mechanisms involved in drought vulnerability or resistance and to adopt the most advantageous tool to monitor these changes. Field spectroscopy, an accessory tool of remote sensing, evaluates the reflectance to collect continuous spectrum from materials. In the conducted study, the potential of using UV-Near infrared (NIR) spectroscopy as a non-destructive and reliable approach in monitoring of drought effects on three Medicinal and Aromatic Plants species (MAPs): Lavandula stoechas, Cistus laurifolius and Pistacia lentiscus from Northern Morocco during dry (July 2021) and wet (March 2022) period was addressed. It was found that Lavandula stoechas species is more impacted by water deficit than Cistus laurifolius and Pistacia lentiscus. Indeed, this species has a lower reflectance in Visible and NIR regions of the spectrum after a period of drought and therefore a higher vulnerability to water deficit than the other two species.

Opis:
In reference to cultural patterns in collectivistic societies, teaching and learning are greatly influenced by the teachers’ collectivistic or individualistic cultural orientation (Kaur & Noman, 2015). However, in dealing with both audiences and their teaching platforms, a chasm appears between methodologies and their applications since collectivistic societies are reluctant to accept methodologies perceived as mere Western innovations. In other words, a seemingly pedagogical incongruence arises where direct individualistic Western influence is perceived as unsuitable to a collectivistic mindset. One must keep in mind that family members in collectivist societies, who view themselves as part of a group rather than independent individuals, seem to feel more interdependent and mutually responsible for each other. In addition to Vygotski’s assertion that children’s cognitive development is enriched through social interaction with more skilled individuals (1978), Bandura (1982) emphasizes that the degree to which learners believe in their own self-efficacy influences their functioning cognitively, motivationally, emotionally, and their decision making process. Also, self-efficacy is perceived to accelerate the process of adapting to a new environment while learners adopt new cultural practices and consent to norms and expectations. In our exploration, second-language learners (SLLs) from collectivistic societies advance academically—English as a second language included—within the frame of sociocultural theory, since they seem to be motivated by their culturally- induced sense of obligation to honor their parents and other group members. These SLLs are positively influenced by their prior experiences with the group’s perceptions and expectations of their capability to learn an additional language (Bandura & Schunk, 1981; Schunk, 1991). Our research seems to indicate that this outcome is significantly affected by the self-efficacy and self-reliance produced by prior successes in challenging tasks that may have been mandated by the SLL’s elders. In addition, SLLs also seem to succeed in accomplishing more challenging goals as they observe their families’ values and traditions even when they are in a society that enforces individualistic values.

Objectives The objective was to characterize and compare SARS-CoV-2 serology among Norwegian school employees and retail employees, and describe preventive measures taken at the workplaces. Material and Methods A cohort of 238 school and retail employees was enrolled to an ambidirectional cohort study after the first COVID-19 pandemic wave. Self-reported exposure history and serum samples were collected at 10 schools and 15 retail stores in Oslo, Norway, sampled at 2 time-points: baseline (May–July 2020); and follow-up (January–March 2021). SARS-CoV-2 antibodies targeting both spike and nucleocapsid were detected by multiplex microsphere-based serological methods. Results At baseline, 6 enrolled workers (5 in retail) presented with positive SARS-CoV-2 serology, higher than the expected 1% prevalence (3%, 95% CI: 1–6, p = 0.019). At followup, school and retail groups presented 11 new seropositive cases altogether, but groups were not significantly different, although exposure and preventive measures against viral transmission at workplaces were different between groups. Self-reported medical history of COVID-19 infection showed that all but one positive SARS-CoV-2 serological findings arising between baseline and follow-up had been diagnosed with virus testing. Conclusions Distribution of SARS-CoV-2 positive serology after the first wave was slightly higher than expected. Distribution of infection was not significantly different between the groups at baseline nor at follow-up, despite difference in exposure and protective measures. Nearly all new seropositive cases discovered between baseline and follow-up, had already been diagnosed, highlighting the importance of extensive viral testing among workers.

Objectives To evaluate prenatal exposure to radiofrequency radiation (RFR) from telecommunication using a mobile phone questionnaire, operator data logs of mobile phone use and a personal exposure meter (PEM). Material and Methods The study included 1228 mother–infants pairs from the Mothers and Children’s Environmental Health (MOCEH) study – a multicenter prospective cohort study ongoing since 2006, in which participants were enrolled at ≤ 20 weeks of pregnancy, with a follow-up of a child birth and growth to assess the association between prenatal environmental exposure and children’s health. The questionnaire included the average calling frequency per day and the average calling time per day. An EME Spy 100 PEM was used to measure RFR among 269 pregnant women from November 2007 to August 2010. The operators’ log data were obtained from 21 participants. The Spearman’s correlation test was performed to evaluate correlation coefficient and 95% confidence intervals between the mobile phone use information from the questionnaire, operators’ log data, and data recorded by the PEM. Results The operators’ log data and information from the self-reported questionnaire showed significantly high correlations in the average calling frequency per day (ρ = 0.6, p = 0.004) and average calling time per day (ρ = 0.5, p = 0.02). The correlation between information on the mobile phone use in the self-reported questionnaire and exposure index recorded by the PEM was poor. But correlation between the information of the operators’ log data and exposure index for transmission of mobile communication was significantly high: correlation coefficient (p-value) was 0.44 (0.07) for calling frequency per day, and it was 0.49 (0.04) for calling time per day. Conclusions The questionnaire information on the mobile phone use showed moderate to high quality. Using multiple methods for exposure assessment might be better than using only one method.

Opis:
The aim of the study study was to model, with the use of a neural network algorithm, the significance of a variety of factors influencing the development of hearing loss among industry workers. The workers were categorized into three groups, according to the A-weighted equivalent sound pressure level of noise exposure: Group 1 (LAeq < 70 dB), Group 2 (LAeq 70-80 dB), and Group 3 (LAeq > 85 dB). The results obtained for Group 1 indicate that the hearing thresholds at the frequencies of 8 kHz and 1 kHz had the maximum effect on the development of hearing loss. In Group 2, the factors with maximum weight were the hearing threshold at 4 kHz and the worker’s age. In Group 3, maximum weight was found for the factors of hearing threshold at a frequency of 4 kHz and duration of work experience. The article also reports the results of hearing loss modeling on combined data from the three groups. The study shows that neural data mining classification algorithms can be an effective tool for the identification of hearing hazards and greatly help in designing and conducting hearing conservation programs in the industry.

Background. Health education is one of the main cores of primary health care (PHC). However, there is limited evidence on the difficulties of implementing health education programs. This study explored the barriers of implementing health education programs in Iranian rural communities. Objectives. A qualitative study with conventional content analysis approach was conducted. Applying purposeful sampling, 34 rural folks and health care providers were employed to participate in the study. Data were collected through individually, semi-structured interviews. Data analysis continued until data saturation, when no new theme or idea emerged. Material and methods. A qualitative study with conventional content analysis approach was conducted. Applying purposeful sampling, 34 rural folks and health care providers were employed to participate in the study. Data were collected through individually, semi- -structured interviews. Data analysis continued until data saturation, when no new theme or idea emerged. Results. Four themes, including “Ineffective teaching and learning processes”, “Lack of health educators’ motivation”, “Communication gaps”, and “Lack of resources and facilities for teaching and learning” emerged as the barriers of implementing health education programs in rural communities. Conclusions. Several executive and communicational problems were identified as the local-level obstacles of implementing health education programs in rural areas. Better understanding on the extensive range of health education barriers in rural areas may be helpful for rural health workers and stakeholders in designing and/or revisiting health education programs in rural communities.
