Burnout of Students in Distance Learning During the Covid-19 Pandemic

With the decline in covid-19 cases and facing the transition from pandemic to endemic, it requires people to be able to maintain health to avoid the terror that is very real for people in the world. As a result of this incident, many countries are reorganizing the paralysis of the economy, society, sports, health, and education. In the world of education, especially in universities, lecturers are required to adapt learning to situations and needs, one of which is through the presentation of material online attractively and attractively according to students so that students will continue to be enthusiastic in the lecture process. Distance learning, carried out from home online, if carried out continuously without presenting attractive, creative, and innovative material from lecturers, is feared to cause negative impacts for students, such as psychological effects, one of which is burnout. The purpose of this study was to determine the level of burnout of students during remote learning during the COVID-19 pandemic. The method used in this study was a survey. The subjects in this study were students of the physical education study program at PGRI Palembang University. Data collection techniques using Burnout questionnaires that are distributed to respondents online with the help of google form.
Predictors of condom use among unmarried sexually active women of Reproductive age in Tanzania

Background: Condom is one of the methods for prevention against Human Immunodeficiency Virus and other Sexually Transmitted Infections. It is also considered an effective method for preventing unwanted pregnancies. Despite the several interventions that have been put to promote condom use, still a large proportion of women do not use condom during sexual intercourse. Objectives: This study aimed at determining predictors of condom use among unmarried sexually active women of reproductive age in Tanzania. Methods: This study used secondary data from the 2015-16 Tanzania Demographic and Health Survey and Malaria Indicator Survey (2015-16 TDHS-MIS). It involved unmarried sexually active women aged 15-49 years. Multiple binary logistic regression was used to determine predictors for condom use at last sexual intercourse. Results: Overall, lower proportion (31.1%) of unmarried sexually active women used condom at last sexual intercourse. The odds of using condom during last sexual intercourse was lower aOR=0.67 and aOR=0.65 for women aged 20-24 and 25+ years respectively). Women who reported higher age (18+ years) at first sex had higher odds (aOR=1.65) of using condom compared to those started sex before 15 years old. Women owning telephone had higher odds (aOR=1.44) compared to women without telephone. Also, higher odds of using condom were observed for women in the Southern, South West highlands, and Eastern zones compared to the Central zone. Discussion: Age, marital union, parity, wealth, ownership of; mobile phone, television, access to newspapers, and radio significantly predicts condom use among unmarried sexually active women of reproductive age in Tanzania. Conclusion: The level of condom use among unmarried women in Tanzania is very low and varies by age, age at sex intercourse, ownership of phone and zones. Targeted interventions are needed to promote the condom use among unmarried women in order to mitigate the risk of HIV and un-intended pregnancies.
The Totally Asymmetric Simple Exclusion Process with a Shortcut of Arbitrary Length

In this work we continue the study of the totally asymmetric simple exclusion process, defined on an open network, consisting of head and tail simple chain segments with a double-chain section, inserted in-between [1,2]. We consider the case when the two branches of the double-chain section are of dierent length, thus modelling a bypass on a linear track. The model was first introduced and studied in [3] for a zero length of the shortcut. However, further study [2] reveals rather different and unexpected results. We study here the interesting case which arises when the network is in the maximum current phase. Preliminary numerical simulations show how the density profileof the middle segment changes from high to low density depending on the length of the shortcut and also on the probability of taking the shortcut. These results may have interesting implications for planning of roadway traffic as well as for better understanding of the behaviour of some processes in biological systems [3,4]. References [1] J.

Online Teaching during the COVID-19 Pandemic: A Case Study of Albania

The spread of COVID-19 has caused the interruption of education in all levels of schools, forcing them to seek urgent solutions to reconfigure traditional education programs for distance learning. The emergency restrictions related to social distancing, gathering, etc., have generated a disruption, resulting in a massive quick shift to distance and online teaching. The disruption of teaching has been highly critical and complex, especially for developing countries due to the lack of technological infrastructure, low Internet access, low level of preparation of teachers and parents to use technology, and lack of learning motivation. This paper aimed at identifying the main teaching practices, challenges, and contextual characteristics that impacted the adoption and use of online teaching solutions, during the COVID-19 outbreak, in a developing country, Albania. The paper reached this goal by providing the results of a survey involving 100 educators from different levels of public education institutions in Albania (high schools and universities). The results revealed that despite a set of challenges faced, the online teaching experience during the pandemic time brought improvements in computer teaching skills and communication with students by using several applications for interactivity.
Sarcopenia in Patients with Liver Cirrhosis Assessed by Skeletal Muscle Ultrasound and Its Relation to Serum Testosterone Level

Background: When it comes to quantifying muscle mass in cirrhotic patients, Computed Tomography (CT) is the gold standard; nevertheless, CT is not practical for muscle measurement due to its high cost, radiation exposure, and logistical issues. Ultrasound detection of quadriceps muscle thickness has been recently presented as a more convenient bedside method to assess sarcopenia. The objective of the present study is to evaluate the role of ultrasound in assessment of biceps and quadriceps muscles thickness and echogenicity index as diagnostic parameters in liver cirrhosis patients and to study the relationship between sarcopenia and testosterone levels in these patients. Patients and methods: A total of 50 cirrhotic patients were enrolled in this study from June 2021 to June 2022 at the Internal Medicine Department of Benha University Hospital. Our study included patients having diagnostic evidence of advanced liver cirrhosis (clinical, laboratory, and/or ultrasonographic) and aged >18 years. Results : Testosterone in men was found to have a favorable and statistically significant relationship with handgrip (r = 0.667, P <0.001). In contrast, it showed significant negative correlations with rectus femoris echo index (r = -0.459, P = 0.008) and F-SARC (r = -0.766, P <0.001). Non-significant correlations were reported between testosterone and biceps echo index (P = 0.523), biceps thickness (P = 0.340), and rectus femoris thickness (P = 0.185). Conclusion: The thickness and echogenicity index of muscle is a reliable index for gauging muscle wasting in cirrhotic individuals. Sarcopenia can be evaluated with ultrasound, which might make it possible to track patients' nutritional condition over time.
Further contribution to the Siwalik flora from the Koilabas area, western Nepal

The present study on fossil plants comprising well-preserved leaf and fruit impressions from the Siwalik sediments exposed near Koilabas in western Nepal is the first detailed and systematic work. The floral assemblage recovered from these sediments is impoverished both in quality and quantity as constituted by 25 species belonging to 22 genera and 15 dicotyledonous families of angiosperms. This assemblage adds significant data to the Siwalik Palaeobotany. On the basis of present assemblage as well as already known data from the area, the palaeoclimate, palaeoecology, and phytogeography of the area during the Mio-Pliocene in the Himalayan foothills have been deduced. The significance of the physiognomic characters of the fossil leaves in relation to climate has also been discussed.
Could the Majority of the Greek and Cypriot Population Be Vitamin D Deficient?

OBJECTIVE: Hypovitaminosis D is prevalent in epidemic proportions in many developed countries. The aim of this study is to investigate the prevalence of adequate 25-hydroxyvitamin D [25(OH)D] levels in two Mediterranean countries, Greece and Cyprus. METHODS: Data such as 25(OH)D, the month of blood sample collection, and demographic information were blindly collected from 8780 Greek and 2594 Cypriot individuals over 5 years. Comorbidities were also recorded for 839 Greek subjects. Univariate and multivariate analyses were used to examine the relationship between these variables and 25(OH)D levels. RESULTS: In the samples studied, 72.7% of the Greek and 69.3% of the Cypriot population sample had inadequate levels of 25(OH)D. The mean level for the Greek subjects was 25.1 ng/mL and for Cypriots 25.8 ng/mL. For both samples, only month and gender were significantly associated with 25(OH)D levels, and the highest mean levels were recorded in September. For the recorded diseases, the lowest levels were recorded in sickle cell anaemia 13.6 ± 10.2 ng/mL, autoimmune diseases 13.0 ± 8.4 ng/mL, and cancer 22.6 ± 9.5 ng/mL. CONCLUSIONS: The prevalence of vitamin D deficiency is paradoxically high in both Mediterranean countries.
Mechanics of musical instruments

The study of the functioning of musical instruments requires knowledge of various branches of mechanics, such as linear and nonlinear vibrations and radiation of strings, plates, bars, membranes, air columns, including the self-sustained oscillations of such systems and fluid mechanics. The aim of this book is to give a systematic account of these phenomena in the context of musical instruments, insisting more on the physical and mathematical methods used to obtain simplified models than on details of the behaviour of particular instruments or specific models.
Aerobiology: Aspects and Prospects

Aerobiology is the study of all biologically significant materials that are transported in the atmosphere. Air-borne bioparticles are either beneficial or hazardous, affecting the health and economic prosperity of man on one hand and serving as bio-indicators on the other. Aerobiology has been used as a discipline and as well as a tool for other disciplines such as medicine (allergology - both human & animal diseases, immunology, occupational hygiene), agriculture (plant pathology, pest management, arthropod dispersal), forestry & gene ecology, meteorology, climatology, biometeorology, microbiology, biodeterioration, indoor air quality, air pollution, industrial aerobiology, cultural heritage, palaeobotany, etc. Aerobiologists should encourage closer collaboration among various disciplines in order to achieve a more meaningful outcome.
Dances with Social Robots: A Pilot Study at Long-Term Care

Dance therapy can have significant physical, emotional and cognitive benefits for older adults. In particular, social robots can be developed to autonomously facilitate dance sessions to engage these individuals with the aim of improving quality of life. To successfully integrate and promote long-term use of social robots into long-term care homes for such recreational activities, it is important to explore both residents’ and staff’s perceptions of such robots. In this paper, we present the first pilot human–robot interaction study that investigates the overall experiences and attitudes of both residents and staff in a long-term care home for robot-facilitated dance sessions. In general, the questionnaire results from our study showed that both staff and residents had positive attitudes towards the robot-facilitated dance activity. Encouraging trends showed residents had higher ratings for statements on perceived ease of use, safety, and enjoyment than the staff. However, the staff had a statistically significantly higher rating for willingness to use the robots for dance facilitation. Some key statistical differences were also determined with respect to: (1) gender within the resident group (men had higher ratings for the robots being useful in helping facilitate recreational activities), as well as between staff and residents (resident men had higher perceived safety), and (2) prior robot experience (residents with limited prior experience had higher ratings on perceived ease of use and perceived enjoyment than staff with the same level of experience). The robot-facilitated dance activity was positively received by both older adults and staff as an activity of daily living that can enhance wellbeing while also being safe, easy to use and enjoyable.
The below-ground carbon and nitrogen cycling patterns of different mycorrhizal forests on the eastern Qinghai-Tibetan Plateau

Mycorrhizal fungi can form symbiotic associations with tree species, which not only play an important role in plant survival and growth, but also in soil carbon (C) and nitrogen (N) cycling. However, the understanding of differences in soil C and N cycling patterns among forests with different mycorrhizal types is still incomplete. In order to determine the similarities and differences of soil C and N cycling patterns in different mycorrhizal forest types, three primary forests dominated by ectomycorrhizal (EcM), arbuscular mycorrhizal (AM) and ericoid mycorrhizal (ErM) trees respectively were studied on the eastern Qinghai-Tibetan Plateau. Indicators associated with soil C and N cycling, including leaf litter quality, soil C and N contents, soil C and N fluxes, and soil microbial biomass C and N contents were measured in each mycorrhizal type forest. The results showed that leaf litter quality was significantly lower with high C:N ratio and lignin: N ratio in ErM forest than that in AM and EcM forests. Soil CO2 flux (508.25 ± 65.51 mg m−2 h−1) in AM forest was significantly higher than that in EcM forest (387.18 ± 56.19 mg m−2 h−1) and ErM forest (177.87 ± 58.40 mg m−2 h−1). Furthermore, soil inorganic N content was higher in the AM forest than that in EcM and ErM forests. Soil net N mineralization rate (−0.02 ± 0.03 mg kg−1 d−1) was lower in ErM forest than that in EcM and AM forests. We speculated that AM and EcM forests were relatively characterized by rapid soil C cycling comparing to ErM forest. The soil N cycling in EcM and ErM forests were lower, implying they were ‘organic’ N nutrition patterns, and the pattern in ErM forest was more obvious.
COVID-19 pandemic and minority health disparities in New York City: A spatial and temporal perspective

New York City (NYC) was the epicenter of COVID-19 pandemic for a long time, and the government introduced a city-wide lockdown policy to mitigate the spread of virus. Minority communities, however, suffered disproportionally high percentage of infection and mortality rates, a disturbing phenomenon that deserves scrutiny. Adopting a spatial and temporal perspective, this study aims to investigate health disparities in this pandemic by focusing on mobility in the city. Considering both public transit and the lockdown policy essential factors that impact infection and mortality, this study introduced a measure indicating mobility-restricted transit as the spatial factor. Additional factors include ethnic minorities based on their nativity and three categories of social vulnerability: socioeconomic status, household composition, and housing type. This study selects eight phases, each of which consists of 2 weeks to derive infection and mortality rates to investigate the impacts of those factors. As infection and mortality data are published based on ZIP code, this study further estimates the infection and mortality rates at a finer level of census tract through spatial apportionment. Results reveal the significant impact of mobility-restricted transit on both infection and mortality and show certain clusters of neighborhoods being highly impacted. In addition, this study identifies neighborhoods where native-born and foreign-born of each ethnic minority (Blacks, Hispanics, and Asians) have high risk of infection and mortality. Through a spatial and temporal perspectives, this study identifies the complexity of patterns in minority health disparities in COVID-19 pandemic, which can inform policy makers for localized support to vulnerable neighborhoods to alleviate minority health disparities.

Using the context of physics problem solving to evaluate the coherence of student knowledge

A combined tool for precision boring and burnishing a tubular workpiece includes a bore head and a burnishing head which are advanced by a feed tube into the interior of the tubular workpiece while the latter is rotated about its axis. In order to reduce the stresses on the three above-mentioned elements and to avoid markings on the finished surface, two of the three elements are connected by a coupling, which while transmitting torque between the two connected elements, permits limited deviations of the axes thereof.
Coercive field of ultrathin Pb(Zr0.52Ti0.48)O3 epitaxial films

The polarization reversal in single-crystalline ferroelectric films has been investigated experimentally and theoretically. The hysteresis loops were measured for Pb(Zr0.52Ti0.48)O3 films with thicknesses ranging from 8 to 250 nm. These films were grown epitaxially on SrRuO3 bottom electrodes deposited on SrTiO3 substrates. The measurements using Pt top electrodes showed that the coercive field Ec increases drastically as the film becomes thinner, reaching values as high as Ec≈1200 kV/cm. To understand this observation, we calculated the thermodynamic coercive field Eth of a ferroelectric film as a function of the misfit strain Sm in an epitaxial system and showed that Eth strongly depends on Sm. However, the coercive field of ultrathin films, when measured at high frequencies, exceeds the calculated thermodynamic limit. Since this is impossible for an intrinsic coercive field Ec, we conclude that measurements give an apparent Ec rather than the intrinsic one. An enormous increase of apparent coercive fie.
Short- and Long-Term Impacts of the COVID-19 Pandemic on Suicide-Related Mental Health in Korean Adolescents

This study investigated the short-term (in 2020) and long-term (in 2021) impacts of the COVID-19 pandemic on suicide-related characteristics in Korean adolescents in comparison with the pre-pandemic period (in 2019) and examined the factors associated with those impacts. Secondary data of the cross-sectional 15th–17th (2019–2021) Korea Youth Risk Behavior Web-based Survey targeting adolescents in school were utilized. The proportions of adolescents with depression, suicidal ideation, suicide planning, and suicide attempts were 26.5%, 12.2%, 3.7%, and 2.4%, respectively. Following an adjustment, depression, suicidal ideation, and suicide attempts significantly improved in the short term and depression and suicide attempts improved significantly in the long term (i.e., 2021), albeit to a lesser degree. The associated variables in the short-term analysis (i.e., 2020) reflected the socioeconomic vulnerabilities (e.g., lower household socioeconomic status [SES], unhealthy status, and unhealthy behaviors), as well as the socioeconomically favorable indicators (e.g., high household SES and high academic achievement). In the long-term, suicidal ideation was no longer associated with a lack of engagement in hand washing, and suicide attempts were no longer associated with the amount of internet time used for studying. For a successful suicide prevention, it is necessary to develop in-school interventions that address the relevant factors identified in this study and the community-based interventions that target out-of-school adolescents.
A STUDY ON THE ENERGETIC EFFICIENCY OF DIFFERENT FAT SOURCES AND LEVELS IN BROILER CHICK VEGETABLE DIETS

This study was undertaken to asses the energetic efficiency of calories provided by different fat sources and levels in Avian broiler chick diets, either on isocaloric or excess energy basis. Therefore, nine isocaloric-isonitrogenous diets were formulated. The control (corn-soybean diet) contained no added fat, while sunflower oil, palm oil, dry fat (Ultrakcal dry) or soy lecithin were incorporated into the other eight diets at the expense of energy provided by yellow corn at 2.5% or 5% of the diet. Four more diets having excess ME were obtained by adding each of these fat sources to the control diet at 2.5%. Each diet was fed to four replicates of seven chicks each, during the starting and growing period until 42 days of age. The obtained results could be summarized as follows: the level of dietary fat in isocaloric -isonitrogenous diets had no effect on dressing percentage, but abdominal plus visceral fat in chicks carcass was increased due to dietary inclusion of fat. Moreover, increasing of the ME content of the control diet by additional fat produced carcasses of higher dressing percentage and more depot fat. 6-Feeding fat-containing diets decreased the moisture and protein contents and concomitantly increased the lipid content in chicks meat. 7- Neither dietary fat source nor its level affected the chicks-meat pH value. However, values of water holding capacity and tenderness of chicks meat were decreased , and color score was increased upon feeding the fat-containing diets. 8-Neither dietary fat source nor its level affected total proteins in the plasma of chicks. On the other hand, concentrations of plasma total lipids, triglycerides and cholesterol were increased concurrently with increasing the dietary fat level.
