Published: June 2022

Social studies learning process has not been implemented optimally. The application of the Outbound variation of the Outdoor Learning method as a solution to this problem . The instrument used was an observation sheet for student creativity and collaboration. The implementation of learning using an outdoor learning strategy with outbound variations is carried out optimally with very good criteria. The application of this method is carried out by inviting students to study outside the classroom (out door learning) to increase student creativity and collaboration in a pleasant learning atmosphere. The outdoor learning approach (outdoor learning) of outbound variations for children is very useful, it is a learning program (training) for children carried out in the open based on the principle of "experimental learning" (learning through direct experience) which is presented in the form of games, stimulus, discussion and adventure as a medium for delivering material. This outbound learning aims to overcome the problems of children who lack motivation in learning activities, improve children's self-competence, develop abilities and creative ideas. The 21st century learning model includes: first, learning is directed at encouraging students to find out from various sources, not being told. Second, learning is directed to be able to formulate problems or ask questions, not just solve problems or answer. Third, learning is directed at training analytical thinking, as in the case of the decision-making process, not mechanistic and routine thinking. Fourth, learning emphasizes the importance of cooperation and collaboration in solving problems.

The effect of mud filtrate and eventually fine migrations in high-quality rocks considerably influence the reading of NMR and conventional logs. It poses a challenge in extracting useful information that can contribute to the petrophysical evaluation of the virgin zone, e.g., the rock quality index. This is critical for determining the permeability index and the saturation exponent n required for accurate determination of the water saturation. The rock quality index is understood as the ratio between free-fluid volume (FFV) and bound-fluid volume (BFV). This is equivalent to the pore-throat radius, which dominates fluid flow, that is negatively affected by the fine migration. This is reflected in a reduction of the porosity filled by free fluid. The free-fluid porosity undercall is corrected with the help of deeper-reading density data. After this correction, the NMR-derived permeability in the flushed zone, probably damaged by migrated fines, is used to calculate the permeability in the virgin zone. The determination of the oil saturation in the flushed zone from NMR logs was done in two ways—first, by applying statistically based machine-learning tools, and secondly, by applying the widely used 2D-NMR method, diffusion vs. T2 maps. Comparative analysis of these two methods shows that both lead to consistent results. The water saturation in the flushed zone is estimated to be eight times higher than in the virgin zone because of the high degree of invasion.

Rainfall in Nigeria is highly dynamic and variable on a temporal and spatial scale. This has taken a more pronounced dimension due to climate change. In this study, Standard Precipitation Index (SPI) and Mann-Kendall test statistical tools were employed to analyze rainfall trends and patterns in Gombe metropolis between 1990 and 2020 and the ARIMA model was used for making the forecast for ten (10) years. Daily rainfall data of 31 years obtained from Nigerian Meteorological Agency, (NIMET) was used for the study. The daily rainfall data was subjected to several analyses. Standard precipitation index showed that alternation of wet and dry period conditions had been witnessed in the study area. The result obtained showed that there is an upward trend in the annual rainfall amount received in Gombe over the last 31 years at a rate of 3.98 mm/year. The results for the forecast shows that the annual rainfall to be received in Gombe continues in a range above the mean which serves as an indication that the decade will experience more wet years than dry years. The study concludes that the pattern of rainfall in Gombe is a cyclic pattern. The current trend may affect soil moisture, flooding and subsequently lead to ecological change. The study recommends that inhabitants of the study areas should plan their cropping season based on climatic information of their area.
Lesión autoinducida por el paciente en la pandemia por COVID-19, una situación de recursos limitados. Revisión de tema
Authors: López Ramírez Viviana , Triana Luis Carlos
Published: June 2022

La ventilación mecánica invasiva (VMI) es una estrategia importante de manejo en el paciente con síndrome de dificultad respiratoria aguda (SDRA). En la pandemia por COVID-19 los innumerables casos de SDRA han llevado al uso de otros dispositivos de oxigenación no invasivos, que han expuesto al paciente a mayor esfuerzo respiratorio, evidenciándose lo que se conoce como “lesión pulmonar autoinducida por el paciente” (P-SILI, por sus siglas en inglés). El objetivo de esta revisión es exponer la evidencia científica disponible relacionada con este fenómeno en el contexto de la pandemia por COVID-19. Se realizó una revisión narrativa de la literatura del tema mencionado; la búsqueda se realizó hasta septiembre de 2020 en las bases de datos Medline, Embase, Central y Google Académico y se seleccionaron los artículos más representativos. La VMI es fundamental en el tratamiento del SDRA, pero en manos inexpertas puede generar lesión pulmonar por diferentes mecanismos. Por otro lado, el uso de otros dispositivos de ventilación no invasiva como la cánula nasal de alto flujo, podrían favorecer la P-SILI, una condición que al parecer, perpetúa la inflamación y lesión pulmonar inicial al paciente en respiración espontánea. La información disponible aún es insuficiente.

Inicialmente envío un especial y cálido saludo a todos los miembros de la Asociación Colombiana de Neumología y Cirugía de Tórax. Siento que mi vínculo con la Asociación Colombiana de Neumología y Cirugía de Tórax data desde cuando elegí la neumología como mi especialidad. El sentido de pertenencia al gremio germinó por voces de mi entonces mentor, el doctor Oswaldo Escobar Chamorro, miembro de número de nuestro gremio. Emergió una empatía por la Asociación mientras progresaba en mis estudios y conocimientos en el área médica, lo que luego, ya en el ejercicio profesional, se me transformó en espíritu de compromiso con la entidad. Y así, me fui involucrando con la asociación: inicialmente como miembro del Capítulo Costa Norte y posteriormente, como integrante de la Junta Directiva Regional, hasta llegar a ser su Presidenta en dos ocasiones.

Vistas la gran labor y los avances de la Asociación como comunidad científica, brotó en mí la ilusión de postularme para la Presidencia Nacional. El sueño se pudo consolidar gracias al apoyo inquebrantable de los miembros y, ahora, como Presidenta para el periodo 2021-2023, pretendo solidificar mis propuestas y mi visión a través de una labor que intento erigir en principios y metas comunes.
TECHNOLOGICAL CHARACTERISTIC OF A NEW APPLE TREE VARIETIES OF VNIISPK SELECTION FOR JAM PRODUCTION
Authors: Levgerova N. S. , Salina Е. S. , Sidorova I. А.
Published: June 2022

The data of the technological assessment for the suitability of new VNIISPK apple cultivars for jam are given: Aleksandr Boyko, Blagodat, Prazdnichnoye, Ivanovskoye and Patriot of winter maturation and Osipovskoye of summer maturation. Antonovka was taken as a standard cultivar. It is shown that according to organoleptic indicators, jam from all cultivars corresponded to GOST 31712-2012 and was at the standard level (4.4 points). However, according to the general tasting assessment, taking into account the appearance and taste, the jam from Patriot surpassed the jam from the standard cultivar; the jam from Blagodat was rated lower than the jam from Antonovka.  A low variation of tasting ratings was noted (V = 2.8%), which indicates the stability of the technological properties of the cultivars on which the consumer quality of the finished jam depends. In accordance with the requirements of GOST 31712-2012 for the content of soluble solids in jam, the studied cultivars are recommended for the production of various types of jam: sterilized, "homemade", unsterilized using a preservative and without. The high content of soluble solids in the jam of Alexandr Boyko and Osipovskoye makes these cultivars very promising for this type of processing, since it allows packing jam into various types of containers, including large ones without preservative. In terms of the content of titrated acids in jam, almost all cultivars were inferior to Antonovka. Only Osipovskoye and Prasdnichnoe met the requirements of the standard for this indicator (at least 0.3%). According to the content of catechins in jam, none of the cultivars exceeded Antonovka (37.9 mg / 100g). Blagodat and Prasdnichnoe contained the lowest amount of catechins in jam (8.4 mg/100 g). As a result of technological study, it was found that the greatest suitability for jam was characterized by Aleksandr Boyko, Osipovskoye, Blagodat and Prasdnichnoe. Jam made from the fruits of these cultivars can be packed in containers of various capacities, including large ones and without the use of preservative.

Published: June 2022

The article presents the results of studies on the effectiveness of minimum tillage, including without the main tillage, when cultivating spring wheat on leached heavy loamy chernozems of the northwestern natural zone of the Trans-Urals. The studies were carried out at the Kurgan Research Institute of Agriculture, a branch of the FGBNU Urfa Research Center of the Ural Branch of the Russian Academy of Sciences from 2014 to 2021, in a stationary experiment, laid down in the 70s of the XX century under the guidance of T.S. Maltsev. For two rotations of grain-fallow crop rotation (fallow - three wheat), the technology, which includes a combined system of tillage in a fallow field and without main tillage in the third and fourth fields, did not yield to classical plowing in terms of wheat yield (2.57 versus 2.62 t/ha). At the same time, it provided an average cost reduction for crop rotation by 7.9% and the highest profitability in the experiment (100% versus 87% for plowing). Studies conducted against the background of fertilizers and means of protection revealed the depressing effect of high pesticide loads on agrocenosis when cultivating spring wheat on a chemical fallow, which led to a decrease in yield relative to plowing on an average crop rotation against the background of nitrogen fertilizers without fungicidal protection by 13.6%, against the background of fertilizers and fungicides - by 10%. On the variants of mechanical and combined (mechanics + chemistry) processing methods, the variation in yield levels relative to plowing was within the experimental error. Significant changes upward or downward have not been established. As a result, it can be concluded that in the conditions of the northwestern natural zone of the Trans-Urals on heavy loamy chernozems, highly profitable production of spring wheat grain is possible in grain-fallow crop rotations within the framework of intensive technologies, with various levels of tillage minimization up to without basic tillage.

Published: June 2022

Based on the Wang-Landau algorithm, the Monte Carlo method was used to perform an energy analysis of the magnetic structures of the ground state of the two-dimensional Potts model with the number of spin states $q=4$ on a triangular lattice, taking into account the exchange interactions of the first $J_1$ and second $J_2$ nearest neighbors. The studies were carried out for the value of the interaction of the second nearest neighbors in the interval $-2.0 \leq J_2 \leq 0.0$. The magnetic structures of the ground state are determined for different values of the interaction of the second nearest neighbors. It is found that a change in the magnitude of the interaction of the second nearest neighbors in this model leads to a change in the magnetic ordering.
Design of Adaptive PID Controller for Lower Limb Rehabilitation Robot Based on Particle Swarm Optimization Algorithm.
Authors: Sabah Noor , Hameed Ekhlas , AL-Huseiny Muayed S
Published: June 2022

The proportional-integral-derivative (PID) is still the most common controller and stabilizer used in industry due to its simplicity and ease of implementation. However, in most of the real applications, the controlled system has parameters that slowly vary or are uncertain. Thus, PID gains must be adapted to cope with such changes.

In this research, an Adaptive Proportional-Integral-derivative controller (APID) is proposed to control the 2-DOF lower limb rehabilitation robot system. The parameters gains of the proposed controller are optimized using the Particle Swarm Optimization algorithm (PSO). The simulation results show no overshoot and zero steady-state error, but large settling time (ts=3.654 sec. for link1 and ts=2.844 sec. for link2) for linear path, and the actual path tracks the desired path with a large error for the nonlinear path. The results illustrate that the robot's performance is inefficient for linear and nonlinear paths when using the APID controller to control the lower limb rehabilitation robot. Therefore, the controller needs to modify for controlling the robot efficiently.
Antibody-dependent Enhancement during viral infections: Chemical and biochemical interactions among proteins
Authors: Zhang Xiaoxiao , Lin Yuhan , Wang Yuchuan , Ouyang Jess Lan , Liu Qiuyun
Published: June 2022

Antibody-dependent Enhancement during viral infections has been reported previously. It is also a concern amid current COVID-19 pandemic. As proteins can interact via ionic bonding, van der Waals force, aromatic stacking, hydrogen bonding and secondary chemical bonding to non-proton cations, these types of weak chemical bonding can synergize independently or collectively to consolidate protein aggregate structures, allowing more efficient viral entry into cells of vaccinated individuals and perhaps trigger respiratory syndromes upon infection of evolved virus with mutations capable of reinforcing weak chemical bonding. Virion production can be lowered with calorie restriction or dietary regimens, consequently imposing a bottleneck in the aforementioned process. Custom-made as well as universal strategies need to be developed to address concerns on various pathogens.

While the social component of decision making is well-studied, a social dimension has not yet been incorporated into existing quantitative models of choice under uncertainty. In this paper we review previous proposals for how best to include a social component into existing models and then introduce a new approach: the Social Expected Utility model. Our approach combines social discounting and expected utility models, and accounts not only for previous findings, but also leads to novel, testable predictions, including a surprising preference reversal effect. We present the results from four empirical studies that compare our model with alternative theories and we conclude that social discounting should be included in our efforts towards more comprehensive choice models.
Programming engagement: Shaping human-robot-public interaction in a smart city robot competition
Authors: Cuevas-Garcia Carlos , O'Donovan Cian
Published: June 2022

This chapter presents a situational analysis of SciRoc, a “Smart city Robots competition”, organised by the European Robotics League (ERL) in partnership with Milton Keynes City Council in the United Kingdom and a number of academic and commercial sponsors. Besides this competition, we use data collected during other ERL competitions in test beds and living labs in Madrid, Oldenburg, Bristol, mainstream media reporting and extensive conversations with participants. We argue that since competitions are constituted by different sets of rules, and since these rules intersect with the values, practices, assumptions, politics, and interests of their sponsors and organisers, they are appropriate sites for studying the institutional shaping of human-robot-public interaction. We identified three modes of human-robot-public engagement: embracing engagement, an open and attentive form of engagement that was sensitive to the needs, interests, and concerns of various participants, sponsors, and members of the audience. Second, bypassing engagement, a more constrained and constraining form of engagement that limited the possibilities of mutual understanding between competition participants and the various publics. Third, prefiguring engagement, a group of previous commitments and expectations that brought the event into being and gave it shape, but that rigidly framed the ways in which publics and participants could engage with each other. These three modes of engagement in turn revealed and were shaped by different logics of social ordering, namely conviviality, control, and care.
Schulstrukturreformen im Kontext der demografischen Entwicklung. Zur Ausbreitung integrierter Sekundarschulformen in Schleswig-Holstein und in weiteren Bundesländern
Authors: Ridderbusch Jens
Published: June 2022

Zusammen mit der PISA-Diskussion und einem deutlichen Schüler*innenrückgang waren in Deutschland seit Mitte der 2000er Jahre zahlreiche Strukturreformen im Sekundarschulbereich zu beobachten. Dabei entstanden verschiedene neue Sekundarschulformen, die die bestehenden Bildungsgänge stärker zusammenführten. Anhand des Fallbeispiels Schleswig-Holstein sowie einer die Bundesländer übergreifenden Betrachtung sollen wesentliche Triebkräfte der Reformdynamik herausgearbeitet werden. Dabei geraten auch Beharrungskräfte in den Blick, die den Schulstrukturwandel bis heute bremsen.
Steuerung der Schulentwicklung bei rückläufigen Schüler*innenzahlen als Erklärungsansatz für divergierende Entwicklungen des Privatschulwesens. Top-down vs. bottom-up am Beispiel von Mecklenburg-Vorpommern und Thüringen nach der Wiedervereinigung
Authors: Kann Caroline
Published: June 2022

In Folge der Halbierung der Schüler*innenzahlen in Ostdeutschland nach der Wiedervereinigung haben die Kultusministerien der neuen Länder im Bereich der Schulentwicklungsplanung mit unterschiedlichen Steuerungsansätzen reagiert. Am Beispiel von Mecklenburg-Vorpommern und Thüringen zeigt der vorliegende Beitrag auf, dass diese Steuerungsansätze eine zentrale Erklärung für den je nach Bundesland unterschiedlich stark ausgeprägten Anstieg von Schulen in freier Trägerschaft liefern. In Mecklenburg-Vorpommern, wo ein Top-down-Steuerungsansatz verfolgt wurde, führten restriktive Vorgaben bezüglich der Aufrechterhaltung von Schulstandorten zu einem starken Rückgang der öffentlichen Schulen bei gleichzeitig starkem Aufwuchs der Privatschulen. In Thüringen, wo sich die Landesebene aus der Schulentwicklungsplanung weitgehend heraushielt, wurden auf kommunaler Ebene seltener Schulschließungen beschlossen und zugleich auch weniger Privatschulen gegründet. Der Beitrag stützt sich auf die Dissertation der Autorin zum Rück- und Umbau von Schulstandorten bei Schüler*innenzahlenrückgang unter besonderer Berücksichtigung des Privatschulwesens.

Authors: Rhishita Jha  , Bharani Anjali , Dharmanshu Chaube
Published: June 2022

Background: Empyema thoracis is an accumulation of pus in the pleural space. It is estimated that 0.6% of childhood pneumonias progress to empyema, affecting 3.3/1,00,000 children. Various treatment options available include antibiotics alone or with chest tube drainage, intrapleural fibrinolytics, video-assisted thoracoscopic surgery, and open decortications.
Aims and Objectives: (1) The objective of the study was to study clinico-epidemiological and lab profile of pediatric patients with pleural effusion of infective etiology and (2) to study outcome and short term follow-up.
Materials and Methods: Prospective observational study conducted from June 2020 to May 2021 at the pediatric department of a tertiary care hospital, central India. Inclusion criteria: Children between 6 months and 14 years diagnosed with pleural effusion clinically and radiologically. Exclusion criteria: Effusion of traumatic or malignant origin. Detailed history, examination, and relevant investigations were recorded. Data were compiled and analyzed. Patients were treated with intercostal drainage, antibiotics and were referred for surgical intervention wherever necessary.
Results: Thirty-five patients were included in this study. The mean age of the patients was 4.4 years. Fever (100%), cough (88.5%) and breathlessness (65.7%) were the most common symptoms found at admission. Staphylococcus aureus was the most common organism isolated from pleural fluid. In the present study, 77% (27) patients were treated with ICD and antibiotics, 11.5% patients required surgical intervention, and 11.5% patients responded to antibiotics alone. The mortality rate in our study was 5.7% and the rest of the patients were successfully discharged and followed up.
Conclusion: Antibiotics and tube thoracostomy are effective methods of treating pyogenic empyema thoracis in children in resource poor settings.
Hepatic and Pancreatic manifestations of COVID-19
Authors: Avinash H Rajanna  , Vaibhav S Bellary  , Arun Udayaraj
Published: June 2022

Background: Since its first detection in November 2019, the outbreak of severe acute respiratory syndrome coronavirus 2 has influenced over 200 countries, areas or territories worldwide. The virus was initially thought to be a primary respiratory pathogen, but has been reported to have multisystem involvement, including cardiovascular, neurological and gastrointestinal manifestations. The manifestations of liver damage are usually mild and generally asymptomatic. While abdominal symptoms such as pain and diarrhoea are a known presentation, little is known about pancreatic injury as a complication of COVID-19 infection.
Aims and Objectives: The aim of the study was to describe the abnormality in liver enzymes and pancreatic enzymes and to correlate it with the severity and outcome of COVID-19 patients.
Materials and Methods: A total of 200 patients were enrolled during the study period from August-2020 to July-2021. Data were collected from case files of patients fulfilling the inclusion criteria.
Results: A cross sectional study conducted among 200 patients showed that the mean aspartate transaminase and alanine transaminase values were 41.89±50.22U/L and 37.69±41.41U/L respectively and mean amylase and lipase levels were 97.77±126.42U/L and 90.34±127.76U/L. The percentage of transaminitis that was present in patients who were discharged was 29.41% when compared to those who died which was 53.33% and this difference is statistically significant(P=0.02).However, there was no statistically significant difference observed in patients with elevated pancreatic enzymes with their outcomes. C
Conclusion: Hepatic injury is more commonly associated with an increased severity of the disease and also as a contributor for the greater mortality of the COVID-19 patients.
Infection related glomerulonephritis due to scrub typhus in paediatric population: A case series and literature review
Authors: Khuntdar Bidyut Kumar , Guchhait Riya , Roy Arghy Kamal
Published: June 2022

Background: Infection-related glomerulonephritis (IGRN) is an immune-complex mediated renal injury occurring simultaneously with the infection. Till date, though rare, all the reported cases of IRGN were caused by either Streptococcus spp. or Staphylococcus spp. Emerging suggestive risk factors for IRGN were diabetes mellitus, malignancy, HIV infection, and alcoholism. IRGN following Rickettsial infection, its disease course, and fatality are unknown.
Aims and Objectives: In the pediatric population most of the cases are diagnosed as post-infection glomerulonephritis that occurred after a latent period. Here we have presented five typical cases of IRGN with its complication caused by atypical organism. From both points of view, the case series is rare and unique.
Materials and Methods: The authors report five cases of IRGN in scrub typhus infection that illustrate the difficulty of its diagnosis and do a brief review of the literature on this topic.
Results: All the five cases were presented with fever, without any Eschar except one. Moreover, they presented with bizarre renal symptoms confounding diagnosis. All the cases had neutropenia and lymphocytosis that was the sole finding to point toward scrub typhus. But none of our cases had developed acute kidney injury as such.
Conclusion: Scrub typhus is an acute febrile illness. Hence, patients with nephritic presentation should be evaluated for Scrub typhus infection if associated with long-term unresolving fever.
Efficacy of admission cardiotocography on neonatal outcome in term pregnancy admitted in labor in a rural-based tertiary care center: A prospective study
Authors: Suchismita Bera  , Debjani Deb  , Rahul Ballov  , Chakraborty Sohanjan
Published: June 2022

Background: Cardiotocography (CTG) is first-line investigation for antepartum and intrapartum fetal assessment. Fetal monitoring during labor helps identifying fetuses at risk of hypoxic damage and helps institute appropriate intervention to optimize perinatal outcome and prevent neurological injuries.
Aims and Objectives: The present study was conducted to evaluate the efficacy of CTG on neonatal outcome and levels of obstetric intervention in term pregnancy admitted in labor.
Materials and Methods: The prospective study was conducted in Bankura Sammilani Medical College and Hospital during June 2019–December 2020 among 180 pregnant women in term having no obstetric complications that warranted continuous monitoring of fetal heart rate admitted in labor. Principles of descriptive statistics were used.
Results: The mothers were classified into three groups such as labor admission test (LAT) reactive, LAT suspicious, and LAT pathological. Majority of the mothers were aged <20 years, nullipara, primigravida, having clear liquor, which underwent emergency LUCS. About 35% mothers were carrying fetus having distress. The newborns of almost 44% mothers were admitted in NICU. The sensitivity of admission CTG to detect intrapartum fetal distress is 84.13%, specificity is 67.52%, positive predictive value is 58.24%, and negative predictive value is 88.76%.
Conclusion: Admission CTG does not benefit the neonatal outcome in normal- or low-risk women and rather results in increased obstetric intervention.
