La resiliencia consiste en iniciar un nuevo desarrollo tras un acontecimiento traumático. Este fue el caso de los estudiantes que se enfrentaron a la pandemia COVID-19. Este estudio se centró en comprender la reacción de los estudiantes de la Facultad de Ciencias de la Información y los factores que influyeron en su resiliencia. El estudio se realizó en dos fases, en la primera se aplicó una encuesta a 149 estudiantes. En la segunda fase, se realizó una encuesta en la que participaron 124 estudiantes. Se utilizó Microsoft Forms® para generar las encuestas y los gráficos. Los resultados indican que, durante la pandemia de COVID-19, los estudiantes sintieron una mayor carga de trabajo en casa que en persona. Emocionalmente, experimentaron depresión y trastornos del sueño; muchos de ellos consideraron que su autoestima estaba dañada. Se observó que los estudiantes son resilientes en la medida en que cuentan con el apoyo de su familia, expresan sus problemas con amigos y seres queridos. También son resilientes cuando se fijan metas y mantienen la calma ante la adversidad. Del mismo modo, los alumnos tienen una actitud positiva ante los problemas y consideran que esto puede hacerles más fuertes. Lo anterior contribuye a comprender mejor cómo la resiliencia ayuda a los estudiantes a alcanzar sus objetivos académicos. Por otro lado, permite generar estrategias en la facultad para apoyar a los estudiantes, con el fin de enfrentar con éxito las dificultades que se presenten

In the animation industry there are different techniques that allow the creation of audiovisual content such as 3D, 2D, Stop Motion animation, etc. In the case of 3D animation, this consists of a process where everything is made of digitally encompassing the creation of characters, settings, objects and the animation itself. In the first stage of a 3D production, it is not required to use highly capable computing equipment until the final stage known as post-production. At this stage, all the elements that will make up the animation are brought together so that it can be approved and distributed on digital platforms. When trying to unite all the elements that make up the animation, they go through a process called rendering that allows us to obtain photo-realistic images and which in turn gives us the final product of the finished animation, for this stage it is no longer possible work with home computing equipment since even the most powerful computers on the market present problems or difficulties when rendering this type of projects. Faced with this problem, many studios and companies resort to the use of so-called “Rendering Farms” or “Clusters”, which consist of the parallel connection of several computing devices, thus achieving that they work as one, allowing greater power and efficiency when it comes to rendering perform tasks that require a lot of processing. Knowing this, the goal of this work is to create a render farm that allows emerging production houses with low resources to implement this tool, helping them complete animation projects that contain complex compositions or that require computing power to render these works

Authors:   Universidad Tecnológica de San Juan del Río, Jaen-Cuellar Jesús Uriel,
Published: March 2024

Solar panel cleaning is an important practice to ensure the performance and efficiency of solar energy systems. This brief description discusses the usefulness of cleaning solar panels and their impact on renewable energy production. The accumulation of dirt and other contaminants on the surface of solar panels can greatly reduce their ability to capture sunlight and convert it into electricity. Therefore, regular cleaning of panels is critical to maintaining their efficiency and maximizing energy production. The benefits of cleaning solar panels are substantial. By removing impurities, better penetration of sunlight is ensured, which translates into higher power generation. This ensures stable performance and increased power generation over time. In addition, regular cleaning prolongs the life of solar panels by preventing damage caused by the accumulation of dirt and other corrosive elements. Clean panels are less susceptible to damage and are less prone to failure

Published: March 2024

The investigation of the extraction of image objects features by filters based on tensor and vector data presentation is considered. The tensor data is obtained as a sum of rank-one tensors, given by the tensor product of the vector of lexicographic representation of image fragments pixels with itself. The accumulated tensor is approximated by one rank tensor obtained using singular values decomposition. It has been shown that the main vector of the decomposition can be considered as the object feature vector. The vector data is obtained by accumulating analogous vectors of image fragments pixels. The accumulated vector is also considered as an object feature. The filter banks of a set of objects are obtained by regularized inversion of the matrices compiled by object features vectors. Optimized regularization of the inversion is used to expand the regions of object features capture with minimal error. The object fragments and corresponding feature vectors are selected through a training iterative process. The tensor and vector approaches create two channels for recognition. High efficiency of object recognition can be achieved by choosing the filter capture band and creating filter branches according to the given bands. The filters create a convolutional network to recognize a set of objects. It has been shown that the obtained filters have an advantage over known correlation filters when recognizing objects with small fragments.

Authors: Rymarczyk Tomasz , Sikora Jan
Published: March 2024

The accuracy of calculations of integrals with logarithmic singularities for two methods, namely the method of ignoring singularities and the method of subtraction (consisting in separating the singular part from the remaining non-singular), are presented in this paper. Only two-dimensional problems, like Dirichlet's problems, as well as acoustic problems formulated in the frequency domain are considered. Problems related to the accuracy of calculations are discussed and the influence of frequency, as well as the influence of the geometry of the analysed area on the accuracy of calculations, are indicated. When we talk about the influence of geometry, we mean not only discretization, but also the configuration of the area, such as the sharp edges of the boundary line, assuming the use of the classic, without any modifications, Boundary Element Method.

Published: March 2024

Prolonged exposure to elevated temperatures exceeding 47°C, which can occur during root canal obturation, can cause damage of both dental and bone tissues. In order to study the temperature distribution on the surface of the tooth root a temperature measuring device with cold-junction compensation is proposed. For in vitro measurement of the temperature distribution on the surface of the tooth, 8 thermocouples placed in direct contact with the cementum of the tooth were used. In order to eliminate the cold-junction temperature variations, the temperature equilibration device and RTD were used. The suggested linear approximation for the thermocouples' conversion function provides a nonlinearity relative error of less than 0.05% for K-type thermocouples and 0.07% for J-type thermocouples over the temperature range from 20 to 60°C.

Authors: Fatima Naseem , Afghan Saera , Ara Yasmeen , Zafar Majida , Hina Hadia , Ahsan Khansa
Published: March 2024

Background: A range of physiologic, metabolic, and gut microbial changes occur during pregnancy. Pregnancy is linked to insulin resistance and hyperinsulinemia, which increase the risk of gestational diabetes. Probiotics are being extensively examined for their potential benefits in the treatment of a variety of disorders. Moreover, there is no local study connected before on the supplementation of probiotics in such cases to find the improvement in glycemic control level and prevention of gestational diabetes (GDM), so this study was planned.

Methods: This one-year randomised control trial was conducted at PIMS Islamabad, Department of Obstetrics and Gynaecology. After receiving informed permission, 126 patients were enrolled in the trial. In group A, patients were given a standard diet plan along with a probiotic sachet daily from 20 weeks of pregnancy until 26 weeks. In group B, patients were given a standard diet plan along with routine vitamins daily for the same period. Patients were followed-up in OPD up to 26 to 28 weeks, and OGTT was done, then GDM was labelled if OGTT deranged.

Results: At the 28th week, in the probiotic group, the mean fasting blood glucose was 78.84±18.42 mg/dl, and in the control group, it was 81.25±22.49 mg/dl (p-value = 0.515). At the 28th week in the probiotic group, the GDM was noted in 12 (19%) patients, and in the control group, it was in 22 (34.9%) patients (p-value = 0.045).

Conclusion: From this study, we may conclude that there is an effective role of probiotic supplementation in the prevention of GDM among high-risk obese pregnant women.

Published: April 2024

Jumlah kendaraan bermotor di Kabupaten Klaten Periode Tahun 2020-2022 mengalami peningkatan. Peningkatan jumlah kendaraan berimbas pada meningkatnya pula target penerimaan pendapatan daerah dari sektor perpajakan. Akan tetapi, dalam periode tahun tersebut, realisasi penerimaan pajak kendaraan bermotor belum mampu meraih target yang telah ditetapkan. Terdapat selisih antara realisasi penerimaan pajak dengan target yang diharapkan menunjukkan masih belum optimalnya kepatuhan dari wajib pajak kendaraan bermotor. Penelitian ditujukan agar diperoleh informasi adanya dampak kesadaran wajib pajak, pengetahuan pajak, serta kualitas layanan fiskus terhadap kepatuhan wajib pajak kendaraan bermotor. Peneliti menggunakan pendekatan kuantitatif dengan populasi berupa seluruh wajib pajak yang terdaftar di Kantor Samsat Pembantu Delanggu. Metode insidental sampling dipilih sebagai cara pengambilan sample dengan responden sejumlah 83 responden. Kualitas data diuji melalui uji validitas dan uji reliabilitas. Data yang terkumpul kemudian dianalisis dengan bantuan SPSS Versi 27.0 serta menggunakan analisis linear berganda. Dilakukan pula uji secara parsial variabel bebas terhadap variabel terikat dengan kesimpulan bahwa variabel kesadaran wajib pajak menunjukkan pengaruh positif dan signifikan, kemudian pengetahuan pajak memiliki pengaruh positif tetapi tidak signifikan dan kualitas layanan fiskus mempunyai pengaruh positif dan tidak signifikan. Selain itu, dilakukan pula uji f atau uji simultan dengan hasil kesadaran wajib pajak, pengetahuan pajak dan kualitas layanan fiskus secara bersama-sama mempunyai pengaruh secara positif dan signifikan terhadap kepatuhan wajib pajak kendaraan bermotor. Hasil dari uji koefisien determinasi sebesar 25,4% yang mempunyai makna bahwasanya variabel bebas dapat menjelaskan pengaruhnya pada variabel terikat sebanyak 25,4%, serta masih terdapat 74,6% pengaruh variabel lain yang belum dapat dijelaskan melalui penelitian ini.

Simulation of the vulnerability of the steppe landscape and climate zone of Ukraine to climate changes based on space image data
Authors: Lybskyi Mykola , Khyzhniak Anna , Orlenko Tetiana
Published: March 2024

Now, the whole world, including Ukraine, is facing one of the biggest environmental problems, namely, climate change. The steppe landscape-climate zone is one of the territories considered the most sensitive to Ukraine's current and future climate change threats. Studying the vulnerability to climate change of the steppe zone of Ukraine based on data from space surveys requires analysing a large amount of objective data, namely the products of remote sensing data processing. The article presents the results of combining remote sensing, geographic information systems, and multi-criteria decision analysis to identify vulnerable areas to the impact of climate change in the steppe landscape-climatic zone. This information will be used to recommend adaptation systems to modern conditions and reduce the impact of adverse climate changes. The proposed decision-making structure was developed in three stages: 1) collection and processing of available data from space surveys; 2) development of a model of vulnerability to climate change of the steppe landscape-climatic zone of Ukraine based on the method of analysis of hierarchies; 3) construction of the resulting map, which includes degrees of vulnerability to climate changes of the studied territory. Modern cloud processing methods for space survey data provide access to a large number of geo-informational products, including the characteristics of the earth's surface and the spatial distribution of climatic indicators accumulated over a long period. These products allow the processing of these data for large areas to be implemented quickly. This technique allows, based on expert assessments, to assess the combined impact of the most significant characteristics of the earth's surface and regional climate, prioritise their impact on the studied territory's vulnerability to climate changes, and implement its quantitative multi-criteria assessment.
