Distance Learning and Character Building in Rural Area During the Covid-19 Pandemic

The COVID-19 pandemic has brought a number of obstacles and challenges in learning. The bigger obstacle is found for schools in rural areas. Starting from the problem of the availability of supporting facilities, parental support, to the problem of teacher readiness in carrying out learning and character education during the COVID-19 pandemic. Therefore this study aims to describe the teacher's strategy in carrying out distance learning and character education in rural area during the Covid-19 pandemic. This research was a qualitative research, involving 13 teachers. The data were collected through observation, interview, and questionnaire. The data analysis was carried out in by using a qualitative descriptive analysis. The data were analyzed through three stages, namely data reduction, data presentation, and data verification. The data were validated through source, method, and theory triangulations. The results of this study indicate that the teachers’ strategies in implementing distance learning include: Whatsapp-based online distance learning, offline distance learning, and mixed distance learning. There were 3 strategies to carry out character education during the Covid-19 pandemic, namely direct feedback through examples or narrative in the text. Examples given were also in the form of pictures; and through a checklist of daily and weekly activities. Various obstacles occured in distance learning and character education. Parents also felt stressed because of the increased burden during the pandemic. Therefore, collaboration between various components is needed to design the most effective learning strategies in rural areas.
Analysis of bistability at the coupling between waveguide and whispering gallery modes of a nonlinear hemicylinder

The optical bistability caused by the coupling between modes of the parallel-plate waveguide and a nonlinear hemicylindrical crystal is studied using theoretical and numerical analysis. In such a system a waveguide channel is parallelly coupled to whispering gallery modes (WGMs) of a hemicylindrical microresonator ensuring bistable behaviour at input intensities of the order of a few MW cm−2. The characteristic minimum switching time of the system (around 30 ps) can be controlled by varying the thickness of the metal layer which couples the waveguide and WGMs. This is conditioned by the change of the quality Q-factor, as well as the coupling coefficient of the resonator. The main advantages of the system are fabrication simplicity, small sizes of the order of 3 µm, integrability with other optical components and the possibility of adjusting the processes by making use of the electro-optical effect.
Assessment of Fetal Dose and Health Effect to the Fetus from Breast Cancer Radiotherapy during Pregnancy

Decision for radiotherapy during the first trimester of pregnancy may occur, as patients may not realize their pregnancy at the very early stage. Since radiation dose can affect fetal development, the aim of this study was to evaluate fetal dose and associated deterministic effects and risks to the fetus from breast cancer radiotherapy of an 8-week pregnant patient. PHITS (Particle and Heavy Ion Transport code System) Monte Carlo simulation and the J-45 computational pregnancy phantom were used to simulate breast cancer radiotherapy from a 6 MV TrueBeam linear accelerator using the three dimensional-conformal radiotherapy (3D-CRT) technique with a prescribed dose to the planning target volume (PTV) of 50 Gy. Once the fetal dose was evaluated, the occurrence of the deterministic effects and risks for developing stochastic effects in the fetus were assessed using the recommendations of NCRP Report No. 174, AAPM Report No. 50, and ICRP Publication 84. The fetal dose was evaluated to be 3.37 ± 2.66 mGy, suggesting that the fetus was expected to have no additional deterministic effects, while the risks for developing cancer and malfunctions were similar to that expected from exposure to background radiation. The comparison with the other studies showed that accurate consideration of fetal position and size was important for dose determination in the fetus, especially at the early pregnancy stage when the fetus is very small.
Econometric Analysis of Dutch Disease Implication of China-Africa Trade

This study revisits the analysis of the Dutch disease implication of China-Africa trade for Africa’s non-mineral resources sectors; specifically, manufacturing and agricultural sectors, while focusing on the trade relationship between China and 27 African countries for the period of 19years, 2001 to 2019. This prompted an econometric analysis with the use of two-step dynamic (difference and system) panel Generalized Method of Moment (GMM) models, which was also complemented with dynamic least squares panel econometric regression. The preliminary analysis revealed that Ethiopia is the largest African trading partner with China, with an average of about 21percent China-Ethiopia trade ratio, while Botswana has the least trade relation with China, with 1.5percent Botswana-China trade ratio. The result of our econometric analyses suggests that higher China-Africa trade has the potential to reduce Africa’s manufacturing value-added. In other words, China-Africa trade is not causing Dutch disease in Africa but has the potential to cause Dutch disease in the future. Furthermore, the result suggests that higher China-Africa trade has the potential to increase Africa’s agricultural sector productivity. This implies that China-Africa trade has no tendency of causing Dutch disease in the agricultural sector. Our results are robust to different data structures for the dynamic GMM model.
Improved Dividend Estimation from Intraday Quotes

Liquid financial markets, such as the options market of the S&P 500 index, create vast amounts of data every day, i.e., so-called intraday data. However, this highly granular data is often reduced to single-time when used to estimate financial quantities. This under-utilization of the data may reduce the quality of the estimates. In this paper, we study the impacts on estimation quality when using intraday data to estimate dividends. The methodology is based on earlier linear regression (ordinary least squares) estimates, which have been adapted to intraday data. Further, the method is also generalized in two aspects. First, the dividends are expressed as present values of future dividends rather than dividend yields. Second, to account for heteroscedasticity, the estimation methodology was formulated as a weighted least squares, where the weights are determined from the market data. This method is compared with a traditional method on out-of-sample S&P 500 European options market data. The results show that estimations based on intraday data have, with statistical significance, a higher quality than the corresponding single-times estimates. Additionally, the two generalizations of the methodology are shown to improve the estimation quality further.
Does Energy Drink Provokes Gait Modifications in Young Healthy Adults?

Energy drinks have become increasingly popular among young adults and athletes in the last few years. Despite their popularity, little research has substantiated the claims of the positive effects on physical performance of popular energy drinks. Most current research focuses on caffeine alone, but does not often look at how mixing it with other psychoactive substances might alter its effects. Purpose: This study aimed to determine the alterations of gait tasks after consumption of three popular energy drinks on young healthy adults. Methods: Fifteen women and five men were recruited, screened, and signed informed consent to participate in this study. All participants were healthy young adults with no apparent comorbidities that might have been impacted by the consumption of energy drinks. Motion analysis was conducted using Movement Lab TM sensors placed at key anatomical points. Subjects were asked for two bouts of gait tasks pre-energy drink consumption, and then repeat the same tasks after energy drink consumption. Results: There were no significant modifications in gait, however, observable trends were detected in postural gait parameters following the consumption of a Rockstar energy drink. Conclusion: We infer that the trends observed could be attributed to the specific key ingredients used in Rockstar and might have caused gait deviations post consumption. Further studies should focus on Rockstar alone and its specific key ingredients of caffeine, guarana, ginseng, and milk thistle to determine their influence on gait deviations.
Phytochemical Contents of Different Parts of the Seeded Raisins from the South‐East Anatolia: Enzyme Inhibitory Potential of Pulp Extracts

In this study, some phytochemical properties of six seeded raisin species that are mainly cultivated in Southeastern Anatolia were investigated. Additionally, some physical and quality characteristics, phenolic contents (by LC‐MS/MS; Liquid Chromatography Tandem Mass/Mass Spectrometer System), anticholinesterase, and antioxidant capacities (DPPH; 2,2‐diphenyl‐1‐picrylhydrazyl free‐radical scavenging, ABTS; 2,2‐azinobis(3‐ethylbenzothiazoline‐6‐sulphonic acid cation‐radical scavenging activity and CUPRAC; cupric reducing antioxidant capacity) of the cultivars were investigated on ground raisins. In all three methods, the antioxidant activity values of seed extracts were determined to be higher than those of leaf and pulp extracts. Remarkably, the seed extract of Banazı Siyahı showed the highest antioxidant activity in ABTS (IC50: 4.35±0.02 μg/mL), DPPH (IC50: 10.78±0.78 μg/mL), and CUPRAC (A0.5: 9.33±0.45 μg/mL) methods. Additionally, the ethanol extracts of all pulp samples showed higher anticholinesterase activity against acetyl‐(AChE) and butyrylcholinesterase (BChE) enzymes than galantamine. According to the LC‐MS/MS results, catechin (21.362 mg analyte/g extract) and epicatechin (44.667 mg analyte/g extract) found to be quite rich in Kerküş seed extract and isoquercitrin (116.873 mg analyte/g extract) and astragalin (31.915 mg analyte/g extract) detected to be quite rich in Banazı Siyahı leaf extract. Considering the mineral content of the varieties and the soil samples they grow in, all of the grape varieties analyzed in the study was found to be rich. Based on these findings, it might be suggested that Banazı Siyahı and Kerküş varieties have potential to be utilized in pharmaceutical and food industries, due to their contents of catechins, isoquercitrin and astragalin.
A Comparative Study of Magnetic Flux Ropes in the Nightside Induced Magnetosphere of Mars and Venus

We analyzed Mars Atmosphere and Volatile Evolution (MAVEN) and Venus Express (VEX) data of magnetic flux ropes observed in both Mars and Venus nightside induced magnetosphere, in order to understand their statistical characteristics and possible formation processes. We statistically identified 382 (286) events at Mars (Venus) via the minimum variance analysis and investigated the flux rope properties including their geometrical configurations of axial core field direction and spatial distributions. Interestingly, there is no significant difference with respect to the variety of the flux rope axial orientation between Mars and Venus, indicating that about at least one fourth of events do not necessitate magnetotail reconnection for their formations. However, the spatial distribution shows that flux ropes at Venus tend to be observed near the central plasma sheet, whereas those at Mars are more spread out. Moreover, the events tend to be observed more frequently in the −E hemisphere, where the solar wind electric field (ESW) is pointing toward the planet, rather than in +E hemisphere, where the ESW direction is away from the planet. The geographical distribution shows that flux ropes at Mars tend to be observed more frequently in the southern hemisphere where the strong crustal magnetic fields are primarily distributed. Therefore, such a tendency indicates that the Martian crustal magnetic fields could play significant roles on generating flux ropes in the nightside magnetosphere of Mars.
Microendoscopic Dorsal Laminectomy for Multi-Level Cervical Intervertebral Disc Protrusions in Dogs

The objective of this study was to evaluate the feasibility and clinical outcomes of microendoscopic dorsal laminectomy for multi-level cervical intervertebral disc protrusions in dogs. Eight client-owned dogs diagnosed with multi-level cervical intervertebral disc protrusions using computed tomography (CT) and magnetic resonance imaging (MRI) were included in this retrospective case series. Microendoscopic dorsal laminectomies (MEL) were performed with an integrated endoscopic system to the cranial and caudal vertebrae of the affected intervertebral joints. Pre- and post-operative neurological status, operation time, intra-operative complications, and postoperative complications were reviewed. Post-operative CT images were obtained to measure the dimensions of laminectomy and compared to those of planned laminectomy. Full endoscopic procedures were feasible in 7 dogs (87.5%) and the laminectomy dimensions were in agreement with pre-operative planning. In all dogs, major intra- and postoperative complications did not occur. Conversion to open surgery was required in one case. Short-term postoperative clinical deterioration was found in two dogs. Long-term clinical outcomes were good and comparable to those reported in previous studies of open dorsal laminectomies. MEL is a promising minimally invasive approach to multi-level cervical dorsal laminectomy for intervertebral disc protrusions. This technique may improve postoperative discomfort compared to the open approach. Further studies are needed to directly compare outcomes between these two approaches.
The Interventions of a Mobile Mental Health Unit on the Refugee Crisis on a Greek Island

This present study concerns refugees and asylum seekers who have been referred to a Mobile Mental Health Unit (MMHU-Ch) in rural Greece on a Northeast Aegean Island during the refugee crisis in 2015. Our objective is the examination and recording of psychopathology characteristics’, the presentation of the therapeutic interventions provided, and the difficulties. The sample is composed of 418 requests made by refugees, asylum seekers, adults, and children. The clinical and demographic data have been gathered from the MMHU-Ch’s charts. The study is retrospective, descriptive with quantitative and categorical variables. The data has been analyzed with the utilization of SPSS. The dominant diagnosis in children involves anxiety disorders, developmental disorders, and PTSD. One noteworthy finding is the high percentage of suicide behavior regardless of psychiatric diagnosis, which should be further examined. As far as interventions are concerned, the conclusions which have arisen are the gradually stronger commitment of the referents, but also the high percentage of requests that dropped out. Further examination of the interventions and their efficiency is recommended as well as probing the features of psychopathology in the long term with a view to clarifying the patronizing and aggravating factors.
The Effect of Educational Service Quality on Career Decision-Making Self-Efficacy and Career Attitude Maturity as PUBLIC VALUES of Airline Service Major

Purpose: This study aims to investigate the relationship between self-efficacy and career attitude maturity in career decision-making of educational service quality developed to improve the quality of education in the Department of Aviation Service and strengthen competitiveness in the department. It is insufficient research to apply educational service quality considering the characteristics of the Department of Airline Service, and it is expected that this study will be used as basic data to help efficient department operation and establish strategies for fierce entrance exams. Method: For empirical analysis, a total of 231 responses were collected from students enrolled in the Department of Aviation Services at two-year and four-year universities located in Korea from September 6 to September 14, 2021, of which 221 were used for empirical analysis, excluding 10 unfaithful responses. In the empirical analysis, frequency analysis, factor analysis of measurement variables, reliability, and validity were investigated through SPSS 21.0. Results: It was confirmed that the reputation factor, a sub-factor of educational service quality, is an important factor in all sub-factors of career decision-making self-efficacy. In addition, It was confirmed that self-evaluation, a sub-factor of career decision-making self-efficacy, is an important factor in career attitude maturity. It was shown that the employment support factors of education service quality were all important factors in the determination, purpose, certainty, and independence of career attitude maturity. Conclusion: Through the results of this study, it was confirmed that aviation service department education service quality had a significant influence on career decision-making self-efficacy and career attitude maturity. To increase college students' self-efficacy and career attitude maturity in career decision-making, it is necessary to accurately grasp the importance perceived by college students, increase the leading performance of aviation service majors, and actively engage in career preparation behavior. The result of this study suggests how the educational service quality in the airline service department currently recognized by students is related to career decision-making self-efficacy and career attitude maturity and suggests improvement measures for the development of the department.

On the Issues of Spatial Modeling of Non-Standard Profiles by the Example of Electromagnetic Emission Measurement Data

This paper examines the possibility of the spatial modelling of the Earth’s natural pulsed-electromagnetic-field measured values, which form a closed profile without the data inside. This geophysical method allows us to map active tectonic movement which breaches the integrity of pipes. During the experiment, 4.5 km of profiles were measured in the Admiralteysky district of St. Petersburg, Russia. Regular electromotive force (EMF) values and anomalous EMF values were obtained, ranging from 0 to 900 µV and above 900 µV, respectively. The anomalous values are associated with tectonic faults in the bedrock. The data obtained are characterized by complex spatial anisotropy associated with the development of two groups of tectonic faults of different orientations. The authors have considered the problems of the spatial modeling of the data obtained. The main problems, the solutions to which should allow the obtaining of adequate models, have been identified. Based on the analysis of the measurement results, geological features of the studied areas, as well as variography, the following possible solutions were proposed: changing the measurement technique; dividing the data array according to the main directions of anisotropy; the need to introduce additional correction coefficients. The problem revealed in this article requires further research on the basis of the obtained results, which will reduce the cost and timing of such studies, and, as a result, give an opportunity to take into account active tectonic disturbances during the construction and scheduled maintenance of underground utilities, which is especially important within the framework of the concept of sustainable development.
Urban Neighbourhood Environments, Cardiometabolic Health and Cognitive Function: A National Cross-Sectional Study of Middle-Aged and Older Adults in Australia

Population ageing and urbanisation are global phenomena that call for an understanding of the impacts of features of the urban environment on older adults’ cognitive function. Because neighbourhood characteristics that can potentially have opposite effects on cognitive function are interdependent, they need to be considered in conjunction. Using data from an Australian national sample of 4141 adult urban dwellers, we examined the extent to which the associations of interrelated built and natural environment features and ambient air pollution with cognitive function are explained by cardiometabolic risk factors relevant to cognitive health. All examined environmental features were directly and/or indirectly related to cognitive function via other environmental features and/or cardiometabolic risk factors. Findings suggest that dense, interconnected urban environments with access to parks, blue spaces and low levels of air pollution may benefit cognitive health through cardiometabolic risk factors and other mechanisms not captured in this study. This study also highlights the need for a particularly fine-grained characterisation of the built environment in research on cognitive function, which would enable the differentiation of the positive effects of destination-rich neighbourhoods on cognition via participation in cognition-enhancing activities from the negative effects of air pollutants typically present in dense, destination-rich urban areas.
Gendered microaggressions towards the “only” women coaches in high-performance sport

ABSTRACT For women, being underrepresented in high-performance sport coaching is endemic. They also often report a sense of minoritisation, and incidents of discrimination. The purpose of the present study was to understand, using a gender-microaggressions perspective, how sexism manifests for women in elite coaching who report to be the “only” woman in their context, how they respond to such experiences, and how such discrimination is enabled. Through interviews with nine high-performance female head coaches globally, the prevalent type of microaggressions experienced were gendered microinvalidations. But findings also demonstrate that these women attempted to resist sexism. Nevertheless, being the “only” women restricted their resistance because they could not form collective power that led to transformations in the coaching culture. More action is required to build critical, evenly distributed masses of women across the coaching pathway. Future research must also address the features of organisational contexts that provide fertile grounds for exclusionary cultures.
Automatic Control for Time Delay Markov Jump Systems under Polytopic Uncertainties

The Markov jump systems (MJSs) are a special case of parametric switching system. However, we know that time delay inevitably exists in many practical systems, and is known as the main source of efficiency reduction, and even instability. In this paper, the stochastic stable control design is discussed for time delay MJSs. In this regard, first, the problem of modeling of MJSs and their stability analysis using Lyapunov-Krasovsky functions is studied. Then, a state-feedback controller (SFC) is designed and its stability is proved on the basis of the Lyapunov theorem and linear matrix inequalities (LMIs), in the presence of polytopic uncertainties and time delays. Finally, by various simulations, the accuracy and efficiency of the proposed methods for robust stabilization of MJSs are demonstrated.
