CHILD PSYCHOLOGICAL DYNAMICS AS PERPETRATORS OF THEFT
Authors: Hardiyanti Rahmah  , Husin  , Sir Ahmad Rizhan  , Abdul Rashid bin Abdul Aziz
Published: November 2022

Child delinquency is an act that violates the norms or rules in society that is committed by children. Child delinquency is a social phenomenon caused by a form of social neglect which ultimately leads to deviant behavior or delinquency. But there are several factors that influence children to do these actions. This study aims to determine the psychological dynamics of children as perpetrators of theft, so they can handle or even prevent other children. This research uses a qualitative method, because this method can be used to explore and understand the meaning of a number of individuals or groups who are considered to have social or humanitarian problems. The results of this study indicate that children commit acts of theft because of a lack of attention from the family or even from their own parents to become a bad figure for their children. Likewise, the influence of peers who are naughty in association can also influence the behavior of children to become naughty. And a bad environment can influence children's behavior to be bad, because children tend to imitate what they see in their environment whether it's good or bad.

Published: November 2022

Performance management in question is with the aim of increasing the strategic focus and effectiveness of the company in ensuring continuous improvement of individual and team performance. The most popular approach is to use the BSC (Balanced Scorecard). Cafe Red&Blue wants to grow and maintain its business. Therefore, in this study we want to design an instrument for measuring performance at Red&Blue cafes using the BSC. The initial stage in designing the instrument is to conduct internal and external analysis to determine the position of the business in the industry and the strategy that must be used. The SWOT approach is used in the analysis of the internal and external environment. From the SWOT analysis, it can be seen that the Red&Blue cafe is in quadrant I position. The strategy that must be applied is an offensive and defensive strategy as a complement. This strategy requires Red&Blue to improve its marketing strategy in order to bring even greater opportunities to the business. The next stage is through the formulation of strategic objectives, the objectives of which are designed; increase profits, increase customer loyalty, improve relationships with new customers, develop quality products with innovation, develop good and quality services, improve employee job satisfaction, increase employee skills, and knowledge employee knowledge. The eight strategic objectives are translated into 2 key financial performance indicator (KPI) perspectives, 3 internal business process KPIs, 4 customer KPI perspectives, and 5 KPI growth and learning perspectives, with targets for each KPI set based on discussions with Red&Blue cafe owners.

Authors: Johari Johari
Published: November 2022

Waqf has become the world's attention because this instrument can be utilized as a solution to world crisis problems. One of the countries with the most significant potential for waqf is Indonesia, which is based on a large number of followers of Islam. The number of adherents of Islam in Indonesia alone reaches 209.1 million adherents of Islam and makes the potential for Indonesian waqf very large. This type of research is descriptive qualitative, using the case research method and collecting data in this study through observation and in-depth interviews with research objects. The technique used in this research is critical and interpretative analysis. Cash waqf can be distributed to beneficiaries for business capital in the agricultural sector as a family food security distribution scheme with several models: first, a profit-sharing method (Mudharabah). Second, a 0% loan (Qard Hasan)"; third, business strengthening (Musyarakah); fourth, alms and grants (khairiyah). The agricultural system is developed into a culture for every family to become food security by implementing an integrated farming system. Agricultural system, "low external input and sustainable agriculture," at home and group/production scale. With this system and a touch of technology, the future is projected as a comprehensive agricultural center. Production and marketing are carried out simultaneously by building an "agricultural industry" and an "agricultural market." Apart from that, it can also be used as an educational, tourism, and cultural village. The academic village is intended as a research and training/educational practicum place. The tourism village is defined as agro-tourism which has high economic value
Experiments with two Approaches for Tracking Drifting Concepts
Authors: Koychev Ivan
Published: November 2022

This paper addresses the task of learning classifiers from streams of labelled data. In this case we can face the problem that the underlying concepts can change over time. The paper studies two mechanisms developed for dealing with changing concepts. Both are based on the time window idea. The first one forgets gradually, by assigning to the examples weight that gradually decreases over time. The second one uses a statistical test to detect changes in concept and then optimizes the size of the time window, aiming to maximise the classification accuracy on the new examples. Both methods are general in nature and can be used with any learning algorithm. The objectives of the conducted experiments were to compare the mechanisms and explore whether they can be combined to achieve a synergetic e ect. Results from experiments with three basic learning algorithms (kNN, ID3 and NBC) using four datasets are reported and discussed.

Authors: Krämer Walter
Published: November 2022

The Maple Power Tool intpakX [24] de nes Maple types for real intervals and complex disc intervals. On the level of basic operations, intpakX includes the four basic arithmetic operators, including extended interval division as an extra function. Furthermore, there are power, square, square root, logarithm and exponential functions, a set of standard functions, union, and intersection. Reimplementations of the Maple construction, conversion, and unapplication functions are available. Additionally, there is a range of operators for complex disc arithmetic. As applications, verified computation of zeroes (Interval Newton Me- thod) with the possibility to find all zeroes of a function on a specified interval, and range enclosure for real-valued functions of one or two variables are implemented, the latter using either interval evaluation or evaluation via the mean value form and adaptive subdivision of intervals. The user can choose between a non-graphical and a graphical version of the above algorithms displaying the resulting intervals of each iteration step. The source code (about 2000 lines of Maple{code) of the extension intpakX is freely available [23].

Authors: Markov Minko
Published: November 2022

We investigate the NP-complete problem Vertex Separation (VS) on Maximal Outerplanar Graphs (mops). We formulate and prove a “main theorem for mops”, a necessary and sufficient condition for the vertex separation of a mop being k. The main theorem reduces the vertex separation of mops to a special kind of stretchability, one that we call affixability, of submops.

Mathematical Modeling for Studying Microbial Processes – Some Examples
Authors: Beschkov Venko , Sapundzhiev Tsvetan , Petrov Kaloyan , Vasileva Evgenia
Published: November 2022

Mathematical modeling may have different purposes in chemical and biochemical engineering sciences. One of them is to confirm or to reject kinetic models for certain processes, or to evaluate the importance of some transport phenomena on the net chemical or biochemical reaction rate. In the present paper different microbial processes are considered and modeled for evaluation of kinetic constants for batch and continuous processes accomplished by free and immobilized microbial cells. The practical examples are from the field of wastewater treatment and biosynthesis of products, like enzymes, lactic acid, gluconic acid, etc. By the aid of mathematical modeling the kinetics and the type of inhibition are specified for microbial wastewater denitrification and biodegradation of halogenated hydrocarbons. The importance of free and immobilized cells and their separate contribution to the overall microbial process is also evaluated for some fermentation processes: gluconic acid production, dichloroethane biodegradation, lactic acid fermentation and monochloroacetic acid biodegradation.
Approximating the MaxMin and MinMax Area Triangulations using Angular Constraints
Authors: Keil J. Mark , Vassilev Tzvetalin S.
Published: November 2022

We consider sets of points in the two-dimensional Euclidean plane. For a planar point set in general position, i.e. no three points collinear, a triangulation is a maximal set of non-intersecting straight line segments with vertices in the given points. These segments, called edges, subdivide the convex hull of the set into triangular regions called faces or simply triangles. We study two triangulations that optimize the area of the individual triangles: MaxMin and MinMax area triangulation. MaxMin area triangulation is the triangulation that maximizes the area of the smallest area triangle in the triangulation over all possible triangulations of the given point set. Similarly, MinMax area triangulation is the one that minimizes the area of the largest area triangle over all possible triangulations of the point set. For a point set in convex position there are O(n^2 log n) time and O(n^2) space algorithms that compute these two optimal area triangulations. No polynomial time algorithm is known for the general case. In this paper we present an approach to approximation of the MaxMin and MinMax area triangulations of a general point set. The algorithm, based on angular constraints and perfect matchings between triangulations, runs in O(n^3) time and O(n^2) space. We determine the approximation factors as functions of the minimal angles inthe optimal (unknown) triangulation and the approximating one.

Prinzmetal’s variant angina during laparoscopy: a case report of vasospasm in the context of cardiac arrest
Authors: Houbotte C , Hankenne L
Published: November 2022

We report the case of a 43-year-old male patient who experienced cardiac arrest during two elective laparoscopies for cholecystectomy. The first procedure was prematurely interrupted after the return of spontaneous circulation (ROSC) while the other was continued under intravenous (IV) perfusion of nitrates (isosorbide dinitrate). At each time, after a cycle of cardiopulmonary resuscitation (CPR) and injection of atropine 0.5 mg, sinus rhythm was restored. Only 3-lead electrocardiogram (ECG) outlines were recorded, showing ST-elevation in lead II. During the first incident, a coronary angiography was performed showing a vasospasm of the left anterior descending (LAD) coronary artery, reversible upon intracoronary injection of nitrates. ECG during catheterization showed ST-elevation in the anterior coronary territory. Calcium-channel blockers (CCB) were prescribed, and oral nitrates were added after the second episode. Cardiovascular prevention consisted in smoking cessation, aspirin and statins. Reporting this case seems to be relevant due to its unusual presentation: Prinzmetal’s angina is usually described as morning chest pains, and it rarely concerns Caucasian men. Moreover, the vasospasm was associated with cardiac arrest and ECG changes suggestive of ST-elevation myocardial infarction (STEMI). The final diagnosis was myocardial infarction with non-obstructive coronary arteries (MINOCA) due to coronary vasospasm, a few minutes after insufflation of pneumoperitoneum. So far, few cases have been described during non-cardiac surgery, and even fewer during laparoscopy. Sharing our experience seems important to attract attention to cardiovascular events that can occur under general anesthesia, especially when clinical presentation is rare.

Context: Therapeutic drug monitoring (TDM) allows personalizing the dose of valproic acid in patients with epilepsy to optimize drug therapy, minimize adverse effects and detect interactions. Aims: To determine valproic acid concentrations in serum samples from people with epilepsy and to analyze its clinical implications. Methods: Cloned donor enzyme immunoassay; descriptive, cross-sectional, non-randomized, convenience recruitment study of 57 voluntary patients with epilepsy (n = 39 male, 68.42%; n = 18 female, 31.58%) aged between 19 and 62 years. After three months of treatment with valproic acid, a single blood sample was collected from each volunteer at a minimal concentration. Results: Serum drug concentrations 51.30-100.10 mg/L (SD 5.94) and level/dose 2.17-5.31 (SD 1.14) were observed. Association was shown between the dose ratio/dose of valproic acid (R2 = 0.8693; p<0.05) and the Mann-Whitney U test (p<0.05). Valproic acid monotherapy and association with carbamazepine and phenytoin are not different between treatment groups (Mann-Whitney U test: p = 0.391 > α = 0.05). Conclusions: Serum valproic acid concentrations are within the therapeutic range, and there is a significant inverse linear correlation between dose ratio/dose, which must be considered to personalize the dose and optimize the pharmacotherapeutic result.
But Why Doesn’t It Get Better? Kinetic Plots for Liquid Chromatography, Part II: Making and Interpreting the Plots
Authors: Broeckhoven Ken , Stoll Dwight R.
Published: November 2022

Choosing a liquid chromatography (LC) column for a particular application can be a surprisingly challenging task. On the one hand, column manufacturers provide us many options to choose from, including particle types, pore sizes, particle sizes, and different lengths and diameters. On the other hand, we usually do not have time to experimentally evaluate many combinations of these parameters, and sometimes we end up picking something similar to the columns that are already available. The “kinetic plot” is a powerful graphical tool that can help leverage the best available theory to help us understand how different combinations of parameters (that is, particle size, length, among others) will perform in regard to the time needed to get to a particular column efficiency (and thus resolution), and therefore make well-informed decisions when choosing columns.
Is Golay’s Famous Equation for HETP Still Relevant in Capillary Gas Chromatography? Part 2: Assumptions and Consequences
Authors: Snow Nicholas H.
Published: November 2022

This installment is the second part of a discussion on the origins and uses for determining the height equivalent of a theoretical plate (HETP) calculations in gas chromatography (GC). This month, I discuss the good and challenging consequences of the Golay theory, its relevance, and some alternatives. Many of the variables that chromatographers view as independent have some interdependence, and we see several limitations of the theory. The complex relationships between HETP and temperature present a particular challenge when thinking about temperature-programmed GC compared to isothermal GC. This article concludes with comments regarding the continued relevance of this classical theory.
Perspectives and Pitfalls in Potency Testing of Cannabinoids by High Performance Liquid Chromatography (HPLC)
Authors: Catani Martina , Felletti Simona , Buratti Alessandro , De Luca Chiara , Cavazzini Alberto
Published: November 2022

Cannabis products have been recently legalized in many countries for recreational or medicinal use. Therefore, rigorous analytical methods to test the potency of samples is required prior to commercialization. In addition, growing interest in the properties of minor cannabinoids has increased the demand for high-throughput methods that can separate the largest number of compounds in the shortest amount of time. High performance liquid chromatography (HPLC) is emerging as the preferred analytical method for potency testing of cannabinoids, but more fundamental work is needed to solve critical issues and contribute to advancing knowledge.

Estimating Evapotranspiration and Crop Coefficient of Vegetable Crops Using Pot Micro-lysimeters
Authors: Octura Josh Elisha , Gadiaware Paisar , Octura Elpidio
Published: November 2022

Irrigation for crop production constitutes the most part of agricultural water worldwide. As most of the water withdrawn by agriculture is lost through crop evapotranspiration (ETC), efficient water management requires accurate and reliable estimation of ETC. To date, available methods for estimating ETC require expensive devices and extensive meteorological information, which become a problem in areas with no instruments and with limited data. The present study aimed to evaluate the performance of a technique to estimate ETC and crop coefficient (KC) of selected vegetable crops (lettuce, mustard, onion, bush bean, and “pechay”) using small plastic pots as micro-lysimeters under screen house conditions. Daily rainfall, reference crop evapotranspiration (ETO), and ETC were recorded. Correlation analysis between ETO and ETC showed a significant positive correlation in lettuce (R = 0.736), pechay (R = 0.687), onion (R = 0.761), and mustard (R = 0.467). The KC values of vegetable crops were obtained and the KC curve for each crop was generated by plotting the KC with respect to the stages of growth. Comparison between KC curves of crops obtained using the present technique with the generalized KC curve by the FAO56 Penman-Monteith (FAO56PM), the standard method for estimating ETC and KC, revealed a significant positive correlation in mustard (R = 0.998), onion (R = 0.982), and bush bean (R = 0.800) – suggesting that the KC curves of most crops obtained by using the present technique is comparable with the standard generalized KC curve by the FAO56PM. Taken together, these findings suggest that the present technique provided a close approximation of the water requirements of the crops tested. Since the technique is relatively simple and requires minimum input parameters for estimating ETC and KC compared to the standard method, the technique may be used as an alternative in remote areas where meteorological information is limited, as well as in places where urban agriculture is commonly practiced.
Bentonite Reinforced Chitosan Scaffold: Effect of Bentonite Exfoliation on Scaffold Properties
Authors: Chakraborty Soma , Pimentel Cristine Joy
Published: November 2022

Chitosan is under investigation as a biodegradable scaffolding material for tissue engineering. Crosslinked chitosan alone cannot form a self-supporting scaffold; hence, it needs reinforcement. The group reported the fabrication of chitosan scaffolds reinforced by exfoliated (E) and nonexfoliated or pristine (P) bentonite and compared their properties. Scaffolds were fabricated through the freeze-drying technique. Bentonite was exfoliated by allowing it to swell in water for a certain time interval. X-ray powder diffraction (XRD) profile showed that swelling reduced the crystallinity of bentonite. Both types of bentonite dispersed well in the chitosan matrix and imparted structural stability to the scaffolds. Scaffolds had interconnected pores; apparent porosity of scaffold with E-bentonite was higher than of scaffold with P-bentonite. The scaffolds swelled almost 35% in 3 d without losing structural integrity. The scaffolds could be compressed to 50% of their original height. The compression modulus of the scaffold with E-bentonite was higher than that of the P-bentonite scaffold.

Published: November 2022

Mango is an economically important fruit crop largely cultivated in the tropics and, thus, is constantly challenged by a myriad of insect pests and diseases. However, no detailed analysis of its resistance gene analogs (RGAs) has been performed, which is a vital resource for plant breeding. Here, we analyzed the RGAs of mango via de novo assembly of transcriptomic sequences and mining of the recently published whole genome sequence (WGS). From the transcriptomic assembly, a core mango RGA database with 747 protein models was established. Meanwhile, 1,775 RGAs were identified in the mango WGS and classified based on conserved domains and motifs: 54 nucleotide binding site proteins (NBS), 107 NBS – leucine rich repeat proteins (NBSLRR), 242 coiled-coil NBS-LRR (CNL), 79 toll/interleukin-1 receptor NBS-LRR (TNL), 78 coiled-coil NBS (CN), 30 toll/interleukin-1 receptor NBS (TN), 45 toll/interleukin-1 receptor with unknown domain (TX), 133 receptor-like proteins (RLP), 917 receptor-like kinases (RLK), 83 transmembrane coiled-coil domain protein (TM-CC), and seven NBS-encoding proteins with other domains. The transcriptome- and genome-wide RGAs have been functionally wellannotated through gene ontology (GO) analysis, and their expression profiles across different mango varieties were also examined. Phylogenetic analyses of expressed and genome-wide RGAs suggest highly divergent functions of the RGAs, which were broadly clustered into 6 and 8 major clades, respectively, based on their domain classification. From the mango RGA transcripts, 134 unique EST-SSR (expressed sequence tags – simple sequence repeat) loci were identified and primers were designed targeting these potential markers. Moreover, comparative analysis of mango with other plant species revealed 65 species-specific RGA families (396 orthologous genes) and detected 1,005 RGA gene duplication events. To date, this is the most comprehensive analysis of mango RGAs, which also provide insights into the dynamic mangopest co-evolutionary arms race and offer a trove of markers for utilization in resistance breeding.
Growth Response of Thunbergia grandiflora (Roxb. ex Rottler) Roxb. (Skyflower) on Shading and Anatomical Characteristics Under Various Soil Series
Authors: Galapon Micah Marie , Quimado Marilyn , Tinio Crusty , Combalicer Marilyn
Published: November 2022

Thunbergia grandiflora Roxb. (Acanthaceae) or “skyflower” is an exotic species that was reported to be aggressively spreading out of control in the tropical and subtropical ecosystems. This study assessed the invasive characteristics of the species by analyzing its growth characteristics on varying shading intensity and soil series, as well as anatomical characteristics in varying soil series. Growth characteristics include the height and root collar diameter (RCD), while anatomical parameters include the thickness of all dermal, ground, and vascular tissues. Based on the results of the shading experiment, T. grandiflora grew significantly in terms of height and RCD under full light conditions (1784.75 lx). The species can survive intense light condition but is suppressed under partial to fully shaded treatments. In the soil series experiment, the highest growth and RCD were observed in the Luisiana soil series with strongly acidic soil (4.1 pH). The leaf and stem anatomical structures of T. grandiflora have the characteristics typical of invasive species that can adapt to certain harsh conditions. This includes the presence of dense non-glandular trichomes, cystolith, multi-layered collenchyma cells in the hypodermis, sclerenchymatous tissues, wider xylem pores, and closely pack parenchyma cells in the stem. Therefore, anatomical structures of this species suggest its ability as an invasive species. Consequently, the invasive characteristics can be suppressed by controlling the shade and soil conditions during the wildling stage of the species. The species can be bioinvasive and the extent may depend on the prevailing conditions in the site. However, further researches on the species’ root physiological and anatomical responses to other biotic and abiotic factors in the environment are recommended. Also, knowing the invasiveness of T. grandiflora will help us identify possible strategies to limit the spread of the species, including early detection of the occurrence of species, avoiding disturbance in the area, and identifying species as biocontrol.
Geomorphometric Characterization and Analysis of the Bued Watershed Using Advanced Spaceborne Thermal Emission and Reflection Radiometer – Global Digital Elevation Model V3 through Geospatial Techniques
Authors: Daipan Bernard Peter
Published: November 2022

The present study analyzed and quantified the linear, areal, and relief geomorphometric aspects of the Bued Watershed in Benguet, Philippines using a 30-m spatial resolution digital elevation model. The study was carried out using geospatial techniques to describe the hydrogeological processes acting on the watershed including its landforms, geologic structure, and terrain features that are relevant in watershed conservation and natural resources management. The study site has a total area of 146.46 km² and a basin length of 23.38 km. Based on the linear parameters, it has four stream orders generated using a 1.5-ha critical source area (CSA). Stream order three, with a total of three stream segments, contributes much higher sediment loads to the Bued River. These stream segments are also controlled by geologic structures with a high possibility of flash floods during a high rainfall intensity. For the areal parameters, the study area was categorized as medium-watershed and less elongated. It has a low drainage density value (1.16 km/km²), which is characterized by a good vegetative cover. The study site has permeable subsurface material and lower relief, which turns out to have a more infiltration capacity. Whereas the drainage texture and form factor values (0.812 km and 0.27, respectively) described the study area with a lower peak flow of longer duration, these values indicate that the flood flows are easier to control. The linear parameters showed that most of the Bued Watershed area (44%) is located at an elevation of > 1000 masl with moderate to steep slopes, which make it more susceptible to erosions and landslides. This is consistent with the relief ratio and relative relief results (0.08 and 0.03, respectively), which suggest that the area is vulnerable to erosion.

Authors: YENİ Gizem , ERDOĞAN Melike
Published: November 2022

Sosyal sermaye birçok disiplinin ilgilendiği ayrıca beşeri ve ekonomik sermaye gibi diğer sermaye türlerine göre de çok daha yeni bir kavram olmakla birlikte normlar, güven, iletişim ve sosyal ağ öğelerini kapsamaktadır. Çalışmada var olan bilgiler ışığında ilişkilerin ve birlikteliklerin, bağlantı ve ağların bireylerin dışında kolektif açıdan da değer yaratan bir sermaye çeşidi olduğu kabulünden yola çıkılmıştır. Hemşehri dernekleri kente göç sonrasında bireylerin yardımlaşma ve dayanışma temelinde oluşturdukları yapılardır ve sosyal sermayenin oluşmasında da akla ilk gelen yapılanmalardır. Çalışmanın amacı; hemşehri derneklerinde güven, iletişim, sosyal ağ ve normlar çerçevesinde sosyal sermaye oluşumunun değerlendirilmesi, sosyal sermaye ve hemşehri dernekleri arasındaki ilişkiyi açıklamaktır. Çalışma nicel araştırma yöntemi olan anket tekniği ile gerçekleştirilmiştir. Çalışmanın örneklemini Edirne Merkez ilçede bulunan hemşehri derneklerindeki 240 üye oluşturmaktadır. Araştırmada elde edilen veriler sosyal ağ, güven, iletişim ve norm boyutları çerçevesinde SmartPls hazır yazılımı ile analiz edilmiştir. Analiz neticesinde katılımcıların sosyal sermaye düzeyinin yüksek olduğu sonucuna varılmıştır.
¿Por qué el trabajo duro de una persona funciona como heurístico de su carácter moral?
Authors: Conejero López Susana , Pascual Jimeno Aitziber , Etxebarria Bilbao Itziar
Published: November 2022

Las personas, por el solo hecho de percibir a un individuo como muy trabajador, tienden a atribuirle características morales positivas. Sin embargo, la evidencia empírica indica que esta es una atribución precipitada, injustificada. Todo sugiere que la percepción de un individuo como muy trabajador funciona a modo de heurístico, el cual nos permite evaluar de forma rápida, aunque tosca, el carácter moral global de dicho individuo. En el presente artículo se analizan los posibles orígenes del fenómeno, las pruebas que hay de su existencia, cómo puede explicarse y sus implicaciones tanto teóricas como prácticas. Este fenómeno puede deberse, en parte, a la fuerte influencia de la ética protestante del trabajo tan dominante en la sociedad occidental. A pesar de que la investigación empírica sobre este fenómeno es aún escasa, los estudios existentes lo apoyan claramente, al menos, en el ámbito laboral y en el contexto estadounidense. Además de la ética protestante del trabajo, este fenómeno puede explicarse haciendo alusión al heurístico de disponibilidad, así como a otros fenómenos muy próximos al citado heurístico: en concreto, hablamos aquí de la correlación ilusoria y del efecto halo. A partir del heurístico de disponibilidad se establece una correlación ilusoria entre el trabajo duro y el carácter moral; por su parte, el efecto halo contribuye a una visión positiva del individuo en ámbitos desconocidos, como puede ser el moral, a partir de su valioso desempeño en el ámbito laboral. El fenómeno que aquí hemos analizado puede acarrear una serie de sesgos, al igual que sucede con otros heurísticos. A pesar de que, en este caso, el juicio sobre la moralidad de la persona que de él se deriva es benévolo, su uso puede comportar efectos muy dañinos, también en el ámbito de la moralidad, por lo que hemos de estar alerta ante su presencia para evitar su posible influjo negativo.

Aim: Inflammatory fibroid polyp is one of the most rarely seen tumors in the gastrointestinal tract. It is clinically confusing as it can cause many different findings. On the other hand, it may histopathologically mimic a malignant lesion. Our knowledge about the presence of platelet-derived growth factor receptor α (PDGFRA) mutation in inflammatory fibroid polyps are increasing. Cases: Herein, histopathological and immunohistochemical findings of three different tumors, two localized in the small intestine and one in the stomach, were interpreted as compatible with inflammatory fibroid polyp. PDGFR mutation analysis was performed in both cases and the presence of mutation was detected. Conclusion: The pathogenesis and histogenesis of inflammatory fibroid polyps are uncertain. We obtained results supporting the presence of PFGR mutations in IFPs mimicking both benign and malignant tumors.

Published: November 2022

A Experiência do Usuário (User Experience - UX) é um atributo de qualidade indispensável para um produto de software. Contudo, há poucas evidências sobre a aceitação de métodos de UX em Ambientes Virtuais de Aprendizagem. Este artigo descreve um estudo exploratório que visa avaliar a aceitação do método UX Curve aplicado no Moodle. Para isso, 23 participantes voluntários usaram o UX Curve para avaliar o Moodle, em seguida, responderam a um questionário baseado no Modelo de Aceitação de Tecnologia. Como resultado, os participantes tiveram uma boa percepção sobre o UX Curve, pois conseguiram se expressar e descrever as experiências de forma fácil. Mas, sentiram dificuldades em recordar experiências vividas no início do uso do Moodle.

Published: November 2022

O feedback dado por professores a estudantes sobre atividades avaliativas é fundamental para a construção do conhecimento e compreensão acerca de sua trajetória de aprendizagem. Entretanto, frequentemente professores não conseguem fornecer feedback de qualidade e em tempo hábil, devido à sobrecarga de trabalho e à falta de tempo, gerando frustração para todos os envolvidos. Neste contexto, a plataforma Tutoria tem o objetivo de apoiar professores na correção de atividades avaliativas de maneira mais rápida, mantendo a qualidade e a personalização. Para isso, Tutoria utiliza técnicas de inteligência artificial para dar suporte na correção de questões discursivas, priorizando a usabilidade.

Published: November 2022

Este artigo tem como objetivo apresentar o desenvolvimento de um jogo, como suporte pedagógico para o trabalho em grupo, promovendo uma didática em rede entre os professores. A metodologia usada foi qualitativa, exploratória, pois, a partir de uma pesquisa bibliográfica narrativa, que serviu como base para a fundamentação, procuramos confeccionar o jogo das matrizes energéticas. Como resultado, criamos um jogo a partir do Construct3 e desenvolvemos com os professores propostas de ensino inclusivo, considerando a abordagem cooperativa com o suporte tecnológico. Concluímos que a criação do jogo pelo próprio professor estimula a utilização de ambientes de ensino cooperativos.
A Relevância e a Relação de Pensamento Computacional e Educação Financeira na Educação Básica Brasileira: Um Levantamento sobre o Entendimento dos Estudantes de Pedagogia, Licenciatura em Matemática e Educação
Authors: Lima Antonio Alexandre , Siqueira Sean Wolfgand Matsui , S. N. Nunes Maria Augusta
Published: November 2022

Pelas linhas da educação, a integração do Pensamento Computacional (PC) e da Educação Financeira (EF) favorecem a inclusão e, como temas inseridos recentemente na Educação Básica brasileira, poucos são os estudos que investigam o que entendem os profissionais da área de educação sobre tais temas (PC e EF), tanto isolados quanto integrados. Para preencher esta lacuna foi realizado um levantamento com a aplicação de questionário espontaneamente respondido por 30 alunos brasileiros das áreas de Pedagogia, licenciatura em Matemática e Educação. Os resultados mostram que 41% entendem o que é PC, 90% entendem o que é EF e 72% percebem a possibilidade da integração desses temas na Educação Básica brasileira.
Disentangling Justice
Authors: Gilgen Sandra
Published: November 2022

What is fair? The choice of an allocation norm, whether it be need, merit or equality, can either foster cooperation or conflict. Because of the general irreconcilability of these principles of justice, people are forced to make complex trade-offs when allocating resources. The resulting decisions are shaped by individual factors and context, but also the situation in which an allocation problem arises. Addressing these three levels simultaneously and taking the inherent interdependency of outcomes into consideration, this book adheres to a mechanism-based approach. Its findings support a functionalist perspective on distributive justice, highlighting the inherent relevance of the relational structure for the choice of allocation norms.
