PAUD Teacher Strategies in Supporting Learning in The Covid-19 Pandemic Period
Authors: Sianturi Fortina Verawati
Published: January 2022

The existence of COVID-19 which still hit Indonesia until in November 2020 had a negative impact on education in Indonesia, especially early childhood education. This makes learning, which was a face-to-face system, must be changed to distance education. In order for learning to continue optimally, of course, the teacher must be able to apply different learning strategies. In the pandemic era, schools implement online learning strategies, including at the Playgroup level. Online learning for children, of course, presents its challenges for the teachers. This study aims to investigate online learning strategies at the playgroup level. Play is also a means for children to channel their great energy and discover new things that were previously unknown in a fun way. And this is certainly different from learning that is understood by adults with all the rules and demands at the end. Playing (while learning) in early childhood has a purpose that adults may not realize, where when a child plays, in fact he is developing the potential that exists within him to become a solid initial capital for himself in the future when facing problems in life. This paper is expected to provide references and education to parents and early childhood teachers in particular to be able to understand the world of early childhood, one of which is by understanding the nature of play and the meaning of play for early childhood. This is obtained by exploring various sources from several literatures from the results of research and thought where the results can be used for early childhood parents and teachers to be more precise in assisting and designing learning for early childhood so that the pearl of early childhood learning, namely playing while learning can be achieved.

Abstrak

Penelitian bertujuan untuk menjelaskan fenomena hasil penilaian belajar  Sosiologi jenjang sekolah menengah atas (SMA) di masa pandemi COVID-19. Evaluasi hasil belajar penting dilakukan karena di masa pandemi COVID-19, peserta didik di Jawa Timur justru dihadapkan dengan berbagai tes dalam menentukan kelulusan. Kebijakan tersebut sebenarnya bertentangan dengan keleluasaan yang disarankan oleh pemerintah, yaitu dengan menerapkan model nontes, seperi portofolio ataupun proyek. Jenis penelitian yang dilakukan adalah kualitatif deskriptif. Informan penelitian adalah guru-guru Sosiologi jenjang SMA yang tergabung dalam Musyawarah Guru Mata Pelajaran (MGMP) Sosiologi Kota Malang yang dipilih melalui teknik purposive sampling. Teknik pengumpulan data menggunakan wawancara dan data penelitian dianalisis menggunakan teknik analisis alir. Hasil penelitian menunjukkan bahwa guru dan peserta didik mengalami tekanan dan hasil tes yang diperoleh oleh peserta didik tidak memuaskan. Fenomena tersebut menjadi ironi dalam dunia pendidikan karena sebenarnya guru dan sekolah tahu bahwa pembelajaran di masa pandemi COVID-19 tidak mungkin optimal seperti pembelajaran tatap muka.

 

Abstract 

The research aimed to explain the phenomenon of sociological learning assessment results of high school students during a COVID-19 pandemic. Evaluation of learning is important to do because in the midst of the existing situation, students in East Java are actually faced with various tests in determining graduation. This policy actually contradicts the flexibility that has been suggested by the government, namely by applying the non-test model. The type of research used descriptive qualitative. Research informants were high school Sociology teachers who are members of the Malang City Sociology MGMP who were selected through purposive sampling technique. Meanwhile, the research data were analyzed using flow analysis techniques. The results showed that teachers and students experience pressure and the test results are certainly not satisfactory. This phenomenon is an irony in the world of education because actually teachers and schools know that learning during a COVID-19 pandemic may not be optimal like face-to-face learning.

Published: January 2022

Modeling of mating curved surfaces for practical use in the design of mechanical engineering products based on a parametric kinematic screw. In mechanical engineering, when modeling conjugate curved surfaces of kinematic pairs, trochoid graphs and electronic modeling installations were used, they had low accuracy and productivity. It is proposed to optimize the process of creating universal graphic tools, where there is, in fact, a graphic representation of the parameters of kinematic conjugate curved surfaces, a change in one of which leads to a change in others, opens up the possibility of obtaining the shapes of parts with predetermined parameters. It should include wishes to expand the capabilities of the propeller diagram [1], taking into account the real picture of the kinematics in the design, which, when the distance between the axes of the propellers changes, would give a real idea of the change in the geometry of the contact surface at each point of the instantaneous movement of the wheels. The kinematic screw has proven itself well for the formation of conjugate ruled surfaces [3], therefore, geometric 3d-modeling of the kinematic parametric screw diagram for the formation of conjugate curved surfaces has become an urgent problem. The technique of 3d-modeling of the kinematic screw diagram is based on the theorems of Professor A.M. Podkorytova [4]. Modeling of mating curved surfaces on the basis of a parametric kinematic screw means that from graphic constructions at any stage of design, you can easily go to the calculation by an analytical method, if you need to check or accurately determine the parameters. It will allow you to visually represent the process of obtaining conjugate curvilinear kinematic pairs, to analyze the influence of each parameter on the profile and its structural dimensions, you can identify errors in the profiling of conjugate curved surfaces where to avoid them, which is what this article is about.

The peculiarities of the use of panoramic windows in the residential segment of the region are determined. An analysis of scientific publications in magazines with the impact - a factor and the approaches to increasing the energy efficiency of the thermal insulation shell of the building with glass elements of the facade are determined. The advantages and disadvantages of the use of panoramic windows in terms of heat engineering properties of a fencing structure are outlined. It is determined that according to the normative method of calculating the given thermal resistance, there may be a significant difference in calculating the entire facade and design for one room. To confirm the comparative calculation, which resulted in the resulting thermal resistance for a fragment of the facade (where there are two windows) is 3,3 m2 K / W (corresponding to the requirements of the normative value), and when calculating the fragment of this facade of a separate room with a panoramic window with a panoramic window. The result of the given thermal resistance is 2,6 m2 K / W (which is significantly lower than the normative value). The factors influencing the technical state of panoramic windows are outlined and lead to a decrease in the heat-insulating characteristics of the enclosing structures of the building; As well as measures and organizational and technical solutions, which allows the use of panoramic windows in modern housing construction. It is proposed for the heating of premises with panoramic windows of the scheme of placement of heating systems, namely: installation of vertical radiators on the side of the double-glazed windows; Planting a convector-type floor battery; arrangement of the system "Warm floor" and combined systems; internally floor convectors; infrared heaters; Installing slit or plinth convectors in the floor below the window, on the wall or ceiling. Recommended investors of new apartments to pay attention not only to the facade of the facade in the design decisions of external enclosures of buildings with the use of panoramic windows, as well as technical solutions of windows, ventilation and heating systems, which significantly affect the energy efficiency of the future apartment.

Published: January 2022

The main mission of civil engineer is to ensure he reliability of the structure with maximum efficiency of time, materials and energy. In construction, everything must be provided in the design workshop - both strength and economic feasibility. Balancing on the "edge of the abyss" requires a precise mathematical apparatus. The modern mathematical apparatus of soil mechanics is based on the solutions of the theory of elasticity and the theory of limit equilibrium. In this case, the calculation of the bases is carried out from the conditions of purely elastic connection and the ultimate loads are determined without connection with deformations. Most of the elastic-plastic deformation - from the end of the elastic stage to the loss of stability is not covered by the calculation models. At the same time, the reserves of the elastic-plastic zone allow to increase the load on the foundation, provided that the subsidence of the elastic stage does not yet reach the maximum allowable value for this structure. The boundary element method (BEM) allows to solve problems of this kind. The main disadvantage of foundations on a natural basis is the complexity of its manufacture and high material consumption. These shortcomings can be eliminated by building foundations in cavities of a predetermined shape, which are formed in the soil. These include foundations in compacted ditches, which are arranged in wells with expansion at the bottom. The soil retains its full-fledged composition, so that the work includes a side surface that receives part of the vertical load and provides significant resistance to horizontal forces. The paper presents a method of integration of a mathematical model of behavior under load of foundations in a compacted pit with a numerical BEM. A theoretical study presents the effect of the addition of sand-gravel mixture on the bottom of the compacted pit on the bearing capacity of pyramidal piles.

The purpose — to evaluate the effectiveness of the developed algorithm for determining the tactics and methods of treating intraarticular fractures in HIV-infected patients. Material and methods. From 2016 to 2020, 56 HIV-infected patients with intra-articular fractures underwent surgical treatment. In the course of treatment, an algorithm developed in the clinic for determining the tactics and method of treating HIV-infected patients was used, which proved effective in treating extra-articular fractures. Results. The results were evaluated in the average expected time of the fracture consolidation of the selected location, as well as 6 and 12 months from the moment of surgery using the algorithm developed by us for determining the tactics and method of treating fractures in HIV-infected patients. Good results (according to the Luboschitz — Mattis scale) were noted in 16 (30,8%), satisfactory — in 27 (51,9%) and unsatisfactory — in 9 (17,3%) cases. For patients of this category, the most typical complications were the rapid progression of deforming arthrosis of the joints, the secondary displacement of bone fragments against the background of bone resorption, and the development of an inflammatory process of predominantly non-infectious etiology. Conclusion. The use of the developed algorithm for determining the tactics and method of treatment in HIV-infected patients with extra-articular fractures, taking into account the effect of HIV infection and antiretroviral therapy on the processes of bone remodeling and soft tissue regeneration, can significantly reduce the number of unsatisfactory treatment results. At the same time, the peculiarities of the effect of HIV infection on the state of cartilage, subchondral bone and synovial fluid determine the nature and risks of postoperative complications in HIV-infected patients. In the future, it is planned to correct the developed algorithm taking into account the data obtained and to carry out a comparative analysis of the treatment results.

Osteopoikylosis is a rare osteochondropathy that does not have specific clinical manifestations. The literature does not sufficiently cover the issues of surgical aspects of the treatment of patients with bone fractures in this pathology. A clinical case of a femoral neck fracture in a 30-year-old patient with a diagnosis of osteopoikylosis established in childhood is considered. In addition to the fracture, the X-ray examination revealed characteristic changes in the proximal metaepiphyses of the femurs and pelvic bones. The patient underwent osteosynthesis of the femoral neck with cannulated screws. During the operation, a number of features associated with changes in bone density were noted. There were no peculiarities of the postoperative period. Osteosynthesis of the femoral neck in a patient with osteopoikylosis is technically possible. The presence of osteosclerosis foci requires more careful monitoring of the trajectory of the guide spokes.

For fixing tibiofibular syndesmosis, a full-threaded cortical screw 0 3.5 mm, or a Tight Rope system is often used. Fixing with a screw restricts the amplitude of movements of the foot. A fracture or loosening of the screw before the onset of fusion of the ligaments of tibiofibular syndesmosis is possible. The screw must be removed to avoid the formation of persistent limitations of the function of the ankle joint. The Tight Rope dynamically fixes the syndesmosis, does not limit the amplitude of movements and does not require removal, but its efficiency is insufficiently proven. The purpose — to study the physiological mobility in the tibiofibular syndesmosis for the subsequent more accurate choice of the fixation method. Material and methods. On 5 cadaver samples, 10 studies of fibular mobility were performed with intact ligaments of tibiofibular syndesmosis and after their dissection under conditions of fixation with a full-threaded screw 0 3.5 mm, a partial-threaded screw 0 4.0 mm, and a Tight Rope system. Results. The amplitudes of mobility in the tibiofibular syndesmosis were determined in an intact state and in a state of fixation with different implants; the best fixator and the technique of its installation were determined. Conclusion. During the experiment, the assumption was confirmed that a partial-threaded screw installed without the effect of tightening does not limit the volume of movements in the tibiofibular syndesmosis, which allows starting early functional rehabilitation and excludes the need for a staged removal of the screw.

The study is aimed at improving treatment of Osgood — Schlatter disease by reducing periods of pain relief and clinical and radiological recovery, minimizing the relapses of the disease and rehabilitation period. The study involved 70 people (aged from 8 to 18 y.o., the mean age 13 y.o.) with a diagnosis of Osgood — Schlatter disease, types 1-4, based on clinical and radiological data. The patients were divided into two groups: basic and control ones, both receiving comprehensive treatment, which included lifestyle correction, physiotherapy, and therapeutic exercises for the knee joints. In addition, each patient of the basic group received one injection of platelet-rich autoplasma, and as a result, in 3 days after the injection the pain syndrome completely stopped. In the control examination one week after the injection, the edema in the upper third of the leg significantly decreased, and the range of motion in the knee joint fully restored. Three months after the injection, all adolescents returned to active lifestyle, physical activity and sports. Complications and relapses of the disease were not observed during monitoring for 12 months. The use of platelet-rich autoplasma stimulating reparative osteogenesis for the treatment of Osgood — Schlatter disease (types 1-4) results in highly effective treatment due to minimally invasive intervention, shortening the time of pain syndrome, and shortening the period of rehabilitation and return to active lifestyle.

The purpose — to analyze the results of surgical treatment of patients with hemangiomas of the thoracolumbar spine by puncture vertebroplasty. Material and methods. Clinical data and results of surgical treatment of 124 patients operated on in 2014-2020 were analyzed. Preoperative examinations included clinical studies, WAS, Oswestry, X-ray, MSCT, and MRI. MSCT and MRI studies were carried out for diagnosis and to study the treatment results. Single hemangiomas were present in 63 (50,8%) patients, 44 (35,4%) patients had hemangiomas at two or more levels. In 17 (13,7%) patients, hemangiomas were present in both the thoracic and lumbar regions. Results. In 87,8% of cases, MSCT studies in the postoperative period showed filling the hemangioma cavity by more than 80%. Control MRI studies 6 months and a year after surgery in none of the cases revealed a continued growth of hemangioma. Pain syndrome according to WAS before surgery averaged 46/56 points, after 12 months — 15/20 points. According to the Oswestry questionnaire, the average score reduced from 32 to 6 points after 6 months. Conclusion. Puncture vertebroplasty with bone cement is an effective, safe and minimally invasive method for treating hemangiomas of the thoracolumbar spine. The main goals of vertebroplasty are to restore the supporting ability of the affected vertebra, achieve analgesic and antitumor effects.
