Published: May 2023

This article aims to find the implementation of religious moderation and the formation of student tasamuh attitudes at MAS Al Huda, Pangkalan Susu district. This research is qualitative, collecting data through observation, interviews, and documentation studies. Primary data sources in this study include; principals, teachers of Akidah Akhlak, School Public Relations, and PKS 3 for Student Affairs and Students. The next step of data analysis is collecting data, reducing data, presenting data, and concluding data. The results of the study revealed that planning was carried out during the preparation of the syllabus and included matters relating to religious moderation in the material of Akidah akhlak. While implementing learning, the teacher uses learning methods that follow the material, such as the lecture method, and even prioritizes group discussions to instill a moderate attitude in students, namely mutual respect, respect, being fair to group friends, and being sporty during the learning process. The implication is that it has an impact on the attitudes that are built in students, such as students having better religious attitudes and social attitudes, such as being obedient to worship, respecting others, establishing intimacy, having social care, having a nationalist spirit, being tolerant, and obeying the rules.

Authors: GÖK Ahmet , KARAMETE Aysen
Published: May 2023

The purpose of this study was to adapt the computational thinking scale developed by Tsai, Liang and Hsu (2021) into Turkish in order to determine the computational thinking skill levels of secondary school students according to such basic elements defined by Selby and Woollard (2013) as abstraction, decomposition, algorithmic thinking, evaluation and generalization and to do the related validity and reliability study. A total of 454 high school students (9th – 12th grade) determined with the convenient sampling method constituted the sample of the study. The original scale was made up of 19 5-point Likert-type items. Confirmatory Factor Analysis (CFA) was performed to examine the conformity of the data collected via the adapted scale to the five-factor structure of the original scale. As a result of CFA, it was seen that the factor structure of the original scale was preserved. The reliability of the scale was checked with the internal consistency coefficient for the whole scale and its factors. The Cronbach Alpha coefficients obtained were .84 and McDonald's omega coefficients obtained were .86. The scale's Turkish adaptation was found to be a valid and trustworthy measurement tool for establishing the computational thinking proficiency levels of students in high school.

Hierarchical Model and Decision Optimization Algorithm for Distributed Data Storage and Processing
Authors: Krotov K.
Published: May 2023

The task of optimizing distributed data storage and processing is difficult to solve in a limited time. In this regard, a hierarchical approach has been applied to solve it, which provides for the presentation of a generalized problem in the form of a set of hierarchically ordered subtasks, for each of which locally optimal solutions are determined at the appropriate hierarchy level. To optimize solutions for distributed data storage and processing, a process model has been formed, presented in the form of a set of hierarchically ordered components, a mathematical model of a hierarchical game, which is a way to optimize solutions at hierarchy levels. In order to determine effective solutions at hierarchy levels, an algorithm for local optimization of solutions based on genetic algorithms has been developed. The construction of data processing schedules assigned to computing devices is implemented using the proposed heuristic procedure. The application of the developed models of the distributed data storage and processing process, hierarchical game models and algorithms for optimizing solutions made it possible to significantly increase the dimension of the problem, take into account the parameters characterizing data transmission channels when optimizing solutions at hierarchy levels, and minimize the amount of unused resources.

Authors: Williams Kelly , Oo Thet , Martirosyan Danik
Published: May 2023

The objective of this literature review was to evaluate the effectiveness of the exploring the effectiveness of lactobacillus probiotics in weight management: a literature review in weight management. Obesity is defined as the accumulation of excessive fat, which may result in many potential health risks. A body mass index over 30 is considered obese, and obesity rates have increased by over 400% since 1975. Obesity is one of the leading underlying causes of health issues in developed nations, causing problems such as cardiovascular disease, stroke, and certain cancers. Additionally, obesity is also known to be heavily associated with type ii diabetes, high blood pressure (hypertension), and musculoskeletal disorders. To combat the issues connected with obesity, diet, and exercise are essential. In this article, we recommend the use of probiotics’ biocompound from the genus lactobacillus in addition to diet and exercise as an intervention for obese individuals. Probiotics may facilitate weight loss by increasing microbiome quantity and variety, regulating immune responses, and improving metabolic rates. An online search was conducted in the following databases: pubmed® and the functional food center’s journal database. Studies published between January 1, 2010, and April 1, 2023, were included. More rcts are needed to increase the certainty of the evidence and to verify our conclusions, especially in those who have conditions that are comorbid with obesity, such as type 2 diabetes.Another major objective of this research will be reviewing accumulated data from the perspective of functional food definition and steps on how to create ideal functional food products. Functional foods, products that contain bioactive compounds, such as vitamins, minerals, antioxidants, and other beneficial substances, are crucial in promoting health and preventing diseases. Functional food science involves isolating and combining bioactive compounds to create functional ingredients that provide targeted health benefits. The development of functional food incorporates a multidisciplinary approach to food science, nutrition, biotechnology, and other related fields. Hence, by accumulating data on functional food science and by using quantum end tempus theories about bioactive compounds, researchers can provide valuable insights for creating ideal and innovative functional food products that meet consumer demands for healthier food options. Keywords:Obesity, probiotics, Lactobacillus, quantum theory of functional foods, type 2 diabetes
PRODUCTIVE PRAGMATISM: Industrial democracy under neoliberal capitalist conditions
Authors: Ravn Johan E. , Imaz Alias Oier , Ortega Igor , Haga Trond Sanne , Greenwood Davydd J.
Published: May 2023

This essay presents two case examples of the context and practices of industrial democracy: Norwegian industrial democracy exemplified with the Aker case and the Mondragon Cooperative Experience (a term Mondragon often uses to describe its whole structure and history). The comparison illustrates the necessity of combining general systems theory, the distinction between political and socio-technical participation, and the role of ethos, worldview, and heedfulness in understanding how these enterprises operate and manage ongoing challenges. Our central motive is to promote the expansion of organizational democracy within the global industrial system as a superior and more humane alternative to global neoliberal capitalism. These are not simple comparisons because these systems have different histories, contexts, and dynamics. In making the comparison, we show that the constant process of balancing and rebalancing political and socio-technical participation is a key dynamic in keeping such democratic systems viable. We also show that enterprise ethos and worldview, far from being an add-on or a “soft” dimension, is the bedrock on which such systems rely. After making this general presentation, we put these systems in motion to show how they address the challenges of downsizing and strategic planning. Downsizing and strategic planning show both systems’ ability to face unexpected events and effectively cope with their potential consequences. We conclude that the differences between the cases show there is no one right way to create democratic organizations, but that paths exist and remain open for many different versions of these more humane and successful industrial organizations so necessary for creating sustainable societies.

Linear polyimides based on both of the 2,2´-diamino-1,1´-binaphthalene enantiomers and their racemic mixture were synthesized and characterized. A two-step synthetic route, consisting of the preparation of the polyimide precursor followed by its thermal imidization at temperatures not exceeding 200°C, was employed. The products were analyzed by FTIR and 1H NMR spectroscopy. All of the tested materials were nearly fully imidized after 25 h. The final polyimides possess high glass transition temperatures, are thermo-oxidatively stable and are soluble in common organic solvents as 1-methyl-2-pyrrolidone, tetrahydrofuran and chloroform; additionally, those prepared from the enantiomers show optical activity. The values of specific optical rotations for the polymers were higher than those for the corresponding monomers. However, the directions of their optical rotations were identical. Due to their rather low molar masses, the final polyimides form brittle self-standing films. Thin layers of these products on porous polyimide substrates were made under forming composite membranes.

Epoxy methacrylate of bisphenol-C-jute/treated jute and their sandwich composites of white coir, brown coir, wild almond, bamboo, betel nut, and palmyra were prepared by a compression molding technique under 5MPa pressure and at room temperature for three h. The neat sample showed almost double tensile strength than its jute composite, while it is comparable for treated jute. The composites revealed substantially improved flexural strength compared to neat. The neat, jute/treated jute and their sandwich composites indicated good impact strength, pretty good Barcol hardness, and fairly good electric strength. The neat sample showed excellent volume resistivity, while jute/treated jute and their sandwich composites revealed reasonably good volume resistivity. The composites showed high water ingress tendency, excellent hydrolytic stability, and different diffusivity in different environments at 30oC. Water ingress trend was observed the same for all the composites in different environments, and it is H2SO4 > HCl >NaOH >H2O>NaCl. The sandwich composites may find their applications as low-cost housing and insulating materials and also for marine vessels.

Abstract. The aim of the article was to study and summarize the information about modern aspects of fusarium ear and grain of wheat, strategically important crop in the Russian Federation. Scientific novelty. As a result of analysis of scientific literature data on fusarial ear blight, the following main factors (features) were identify that develop ideas about this branch of knowledge: the biology of pathogens, their ecological plasticity; the difficulty of visual identification of phytopathogenic micromycetes of the Fusarium genus; specific etiology and harmfulness of the disease; insufficient effectiveness of measures to protect crop. Methods. In the process of research, by using analytical and statistical methods, the collection, analysis and generalization of information on biological properties, intrapopulation variability, the ability to produce mycotoxins dangerous for humans and animals, and other properties of phytopathogens of the Fusarium genus were carried out. Results. The information about significant factors causing the spoiling of an agricultural crop was systematized, and the urgency of the problem of fusarium ear and grain of wheat in the Russian Federation was shown. From the analysis of the data obtained, it follows that to control the destructive disease of wheat, it is necessary to study in depth the characteristics of the pathogen, and carry out a set of protective measures with timely identification of the phytopathogen. The presence of unresolved issues causes the continuation of research on the development of genetic methods of fusarium pathogen indication, assessment of the species composition of fungi and methods of forecasting their epiphytotic distribution; fungicide preparations using modern achievements of biotechnology, including nanotechnology and chemical synthesis; instrumental base for monitoring wheat crops for seeding with fusarium pathogens.

Abstract. The study of phytobiotics application is one of the topical directions in the strategy of antimicrobial resistance containment. The aim of this work was to study the effects of separate and combined use of enrofloxacin and phytobiotic drugs in 400-day-old laying hens. Methods. The studies were conducted on four groups of Loman-classic layers; in the course of the experiment, enrofloxacin and a phytobiotic based on sea buckthorn cake and mustard, cedar and sea buckthorn oils were introduced into the diet. Results. It was found that the use of drugs had no significant effect on the composition of microflora and the level of antibiotic resistance of gastrointestinal bacteria in chickens because by the age of 400 days the intestinal microbiomes of laying hens were already formed, stable and contaminated with AMR agents. Also when combining antibiotic and phytobiotic there was an increase in egg laying rate, average egg weight, accelerated excretion of enrofloxacin from the body of layers and reduction of its content in the egg to the detection limit. While in the group of laying hens receiving only enrofloxacin, its residual content in the egg was detected 2 weeks after cessation of its introduction. Thus, in the course of this research, the most optimal was the combined use of enrofloxacin with a phytobiotic drug, which had the most noticeable positive effect on metabolic parameters, productivity and egg quality. The novelty of the work is to obtain data on the effect of phytobiotic drug on a number of health indicators, productivity of laying hens and egg quality, and the selection of promising scheme of its use.

Se comparó los niveles del Pensamiento Crítico (PC) de enfoque cuantitativo con diseño descriptivo y transversal, en colegios privados con metodologías distintas, uno con Modelo Pedagógico Tradicional (MT) y el otro con Modelo Pedagógico basado en la Enseñanza para la Comprensión (MPEC), el cual utiliza estrategias constructivistas en el aula. La muestra estuvo compuesta por un total de 138 estudiantes entre 15 a 18 años del Nivel Medio, seleccionados de forma aleatoria; siendo así 69 participantes de cada modelo. El instrumento utilizado para la medición fue la Prueba de Pensamiento Crítico - Watson Glaser en su versión en español. Los resultados indican diferencias significativas en las cinco dimensiones factores: inferencias, suposiciones, deducciones, interpretación de la información y análisis de argumentos, con una posibilidad de 5% de error admisible, en donde los estudiantes del MPEC obtuvieron mejor rendimiento. Se recomienda incluir en los programas de las instituciones educativas el desarrollo de las habilidades del PC, en base al MPEC.

Purpose: The given study was done to find out the changes in biochemical profiles before and after nutritional rehabilitation of the children admitted at the Department of Paediatrics, Assam Medical College with severe acute malnutrition (SAM). Materials and Methods: A hospital based observational study was conducted from May 2020 to April 2021 with 55 consecutive cases of SAM. Vitros System 5600 was used for analysis of 13 biochemical parameters. Results: The mean values of serum sodium, potassium, and chloride at admission were 134.59±19.37 mEq/L, 4.22±0.80 mEq/L, and 101.12±16.36 mEq/L and that after rehabilitation were 136.66±19.95 mEq/L, 4.42±0.68 mEq/L, and 103.97±4.83 mEq/L. While that for magnesium, calcium, and phosphorous on admission were 2.11±0.38 mg/dL, 8.70±1.00 mg/dL, and 4.33±1.23 mg/dL and that after rehabilitation were 2.10±0.29 mg/dL, 9.45±0.65 mg/dL, and 4.76±0.84 mg/dL, respectively. The mean values of serum total protein, albumin, globulin, and A: G on admission were 6.53±1.44 g/dL, 3.30±0.88 g/dL, 3.23±0.87 g/dL, and 1.06±0.33, respectively, and that after rehabilitation were 6.84±0.98 g/dL, 3.86±0.57 g/dL, 2.98±0.69 g/dL, and 1.34±0.28, respectively. The mean of urea and creatinine on admission were found to be 26.25±19.30 mg/dL and 0.34±0.24 mg/dL, respectively, and that after rehabilitation were 23.91±11.76 mg/dL and 0.31±0.15 mg/dL respectively. Random blood sugar (RBS) on admission was 85.20±17.88 mg/dL and that after rehabilitation was 94.18±14.82 mg/dL. After rehabilitation, the mean value of calcium, phosphorous, albumin, A: G, and RBS were significantly raised. The minimum duration required for rehabilitation was 12 days with prevalence being maximum among the Tea-tribes (80.00%). Conclusion: The biochemical derangements in a patient with SAM are associated with significant morbidity and get improved after nutritional rehabilitation.
How well are we prescribing medications to our children?
Authors: Rajeev Manu , Bhaskar Vikram
Published: May 2023

Introduction: Prescription errors are common and every step in the process of writing a prescription has the potential for error. These errors can be broadly attributed to the lack of knowledge or lack of skill. Poor legibility, inaccuracy in writing, incomplete prescriptions, omissions, and use of abbreviations are the most common type of errors. Objectives: The primary objective of our study was to assess the completeness and legibility of the prescriptions. This is to estimate the rates of skill-based errors. Secondary objective of this study was to assess the appropriateness of the prescriptions using the pediatrics: Omission of Prescriptions and Inappropriate prescriptions (POPI) tool. Methods: This was a cross-sectional study, conducted in the pediatric outpatient department of a tertiary teaching hospital in New Delhi, India. Prescriptions received by outpatients attending both the general and special pediatric clinics were collected and evaluated using the World Health Organization Guide to Good Prescribing and the Medical Council of India guidelines. Results: A total of 343 prescriptions were assessed, in which 753 drugs were prescribed. A total of 1709 errors were uncovered pertaining to the completeness of the prescription. A majority of the prescriptions were written by postgraduates trainees (206), followed by senior residents (61), consultants (42), and junior residents (20). Abbreviations were used while mentioning the drug names in 53.64% prescriptions. The mean legibility score of all prescriptions was 3.35. Forty (11.66%) prescriptions were found inappropriate as per the International POPI tool. Conclusion: The legibility and completeness are largely overlooked yet crucial to the “Art of Prescription Writing.” They deserve as much awareness and education as the appropriateness of the drugs prescribed. The international POPI tool is a promising tool to analyze the appropriateness of pediatric prescriptions.
Extraskeletal mesenchymal chondrosarcoma of the abdomen: A rare clinical presentation

Published: May 2023

Extraskeletal mesenchymal chondrosarcoma (EMCS) is a rare malignant soft tissue tumor of chondroprogenitor cell origin. Originally, it was restricted to the bone only but that is no longer the case. Recent literature reports that 20–33% of these tumors occur at the extraskeletal sites. We report one such case, in which the tumor involved the anterior abdominal wall muscles and also had a large intra- abdominal mass that covered a large part of the peritoneal cavity. The clinical features and computed tomography findings suggested the diagnosis of a malignant desmoid tumor with intra-abdominal extension; however, the histopathological examination and the immunohistochemistry proved the tumor to be EMCS. The case is reported due to the dilemma in diagnosis, its rarity, large size, parietal, and intra-abdominal extension with multiple site involvement.

Published: May 2023

Dermatofibrosarcoma protuberans (DFSP) is a rare and low-grade sarcoma of fibroblast origin with a tendency to invade and recur locally. The most common sites of origin of DFSP are the head, neck, and extremities. However, DFSP breast has also been reported. It infiltrates surrounding subcutaneous tissue and fascia, with an incidence of <2% for lung metastases. Surgery being the main modality of the treatment, literature has shown that radiation therapy also plays an important role to improve local control in case of recurrent tumors. In this article, we will be discussing one such rare case of DFSP in a recurrent setting and the role of radiation therapy.
