The Impact of Scratch-Assisted Instruction on Computational Thinking (CT) Skills of Pre-Service Teachers

The present study aimed to determine the effect of Scratch-assisted expressions and applications on the Computational Thinking skills of pre-service teachers. For this purpose, the research was designed with an exploratory sequential design, a mixed research method. Thirty-three pre-service teachers participated in the study. Data were collected with Computational Thinking Scale before and after the applications conducted in the Instructional Technologies course, and with a survey form developed by the author and face-to-face interviews conducted with the participants at the end of the course. Based on the data obtained, it was determined that the applications conducted in the course improved the Computational Thinking skills of the participants. Although the improvement did not differ based on gender, it was determined that the differences were significant based on creativity, algorithmic thinking, and critical thinking sub-dimensions. Furthermore, it was observed that there was a positive and significant correlation between Computational Thinking and academic achievement. Also, pre-service teachers stated that Scratch applications contributed to the acquisition of Computational Thinking skills. It was suggested that the present study findings would contribute to future studies on Computational Thinking acquisition in similar courses.

The roles of Information and Communication Technology (ICT), and the Data Management Scheme (DMS) in smart grid technologies were also presented with respect to the Oman national power grid. Furthermore, the topologies of energy sales and smart metering were considered as some of the salient benefits of the integration of smart grid technologies in the Sultanate power grid.
Study of Integrated Antennas-Filters on Dielectric Resonators

New structures of dielectric resonators, simultaneously performing the functions of antennas and input filters of transceiver-transmitting devices of communication in the microwave wavelength range, are proposed. The new structures have the form of coupled systems of dielectric resonators, some of which are located in the segment of the evanescent waveguide and perform the functions of a band-pass filter, and the other part of the resonators are located in open space and perform the functions of an antenna system. A part of the resonators of the antenna subsystem has the form of dielectric semi-cylinders glued onto a metallic conductive screen and plays the role of directors forming the radiation characteristic. Two cases of the same and different in shape and material dielectric resonators are considered. For the case of dielectric resonators of different types, using the perturbation theory, a system of equations was obtained for the coefficients of the expansion of the scattering field from the known coupled oscillations of the system. Using the developed theory, the frequency dependence of the reflection coefficient of the proposed antenna-filters was calculated. It is shown that the proposed structures are characterized by much more rectangular amplitude-frequency characteristics, which allows to effectively solve the problems of electromagnetic compatibility of several communication systems using adjacent bandwidths. An additional advantage of the considered antenna filters are smaller dissipative losses, which is important for reducing bit errors. Calculated radiation patterns of antennas in the far zone. It is also shown that the radiation characteristics of the antennas do not change, or change only slightly compared with antennas made only with the help of similar structures of dielectric resonators. The obtained simulation results can significantly reduce computation time and optimize complex communication systems that simultaneously perform channel separation and radiation functions.
RE-UNITING A PEOPLE SEPARATED BY ‘ARTIFICIAL’ BOUNDARIES USING 100 WORDS: AN AUTOETHNOGRAPHY ACCOUNT OF MALOZI, BASOTHO AND BATSWANA OF SOUTHERN AFRICA

Scholars in this study interrogated the Malozi of Zambia, Batswana of Botswana and Basotho of Lesotho and established their purported common ethnic heritage in a quest to contribute to the attainment of the Sustainable Development agenda. The researchers applied Autoethnography and interrogated similarities and differences in 100 purposively selected words. 100 words were selected across themes common to humanity as follows: (i) human body, (ii) family, (iii) environment, (iv) food, (v) animals, and (vi) religion. Finding showed a 100 percent level of similarity across the six themes above with minor variations. Therefore, commonalities in the use of words among the three ethnic groupings is a pointer to a common heritage despite being separated by geographical boundaries. Equally, minor differences in language pronunciations exist but not profound enough to warrant polyacculturation. Thus, blurring the ‘artificial’ boundaries in existence as perceived by members of those groups. This discourse spurs a realization of a common culture and identity.
Bio-fortified maize: Cornerstone in plant breeding to combat hidden hunger in developing countries

Received: 20 December 2020 Revised received: 07 March 2021 Accepted: 20 March 2021 Malnutrition has been one of the major global health problems mainly in underdeveloped and developing world causing massive economic damage as well as distressing human life. Deficiency of useful micronutrients like vitamins and minerals including low level of availability of better quality protein causes hidden hunger which can be alleviate with the help of genetic bio-fortification of crops. Besides all the challenges, biofortified maize crops like quality protein maize along with the provitamin A and Zn hold a great future to address the malnutrition challenge combating the deficiency of malnutrtients. This is the most sustainable, cost-effective and potentially wide-reaching approach which can bridge the gap between agriculture and nutrition. Biofortification can be achieved both by agronomic and genetic approaches. The Importance, genetics and potential of bio-fotification is thoroughly reviewed to provide useful findings for new readers and researchers.

Diversity of Batrachospermales (Rhodophyta) in the Iberian Peninsula

Fifty-four streams of the Iberian Peninsula were investigated to document the species richness and phylogeny of Batrachospermum and morphologically similar genera, determine phylogenetic affinities of taxa and infer biogeographic trends. Species were identified using morphology and DNA sequence data for the rbcL gene as follows: Batrachospermum gelatinosum, B. pozoazulense, Paludicola keratophyta, Sheathia arcuata, S. boryana, S. confusa, Torularia atra, Virescentia helminthosa, V. vogesiaca, and Volatus carrionii. Batrachospermum gelatinosum and S. boryana were most frequent (sampled from 16 and 11 streams, respectively). Torularia atra and V. vogesiaca were each collected in a single stream, whereas the other five taxa were present in three to six streams. Virescentia vogesiaca is well known from other parts of Europe but had previously not been reported from the Iberian Peninsula. Biogeographic trends based on DNA sequence data show a flora with most species being well represented in parts of Europe, two taxa (B. gelatinosum and V. carrionii) that are shared between Europe and North America, one between Europe and South America (Paludicola keratophyta) and one cosmopolitan species (T. atra). Previous studies reported twelve taxa in the region using current taxonomy. This study has confirmed seven of these taxa with sequence data and morphology.

Social representation on the learning of Dentistry students from the Federal University of Maranhão included in the curricular internship in Primary Health Care

This study aimed to identify the social representation on the learning of students of the Dentistry course at the Federal University of Maranhão, at the end of a curricular internship in Primary Health Care, and compare the results with the current National Curricular Guidelines. A qualitative study was carried out using a questionnaire, an instrument used to assess the internship, and only the first question was of interest to this study. In this question, students were asked to evoke five words that demonstrated their learning at the end of the internship in increasing order of importance. The questionnaire was completed by graduates from the 5 period between 2016 and 2019, totaling 100 evaluations. A structural approach and Prototypical Analysis were adopted, considering the frequency and order of words, composing a central and peripheral core. Software OpenEVOC® identified 500 evoked terms and 10 that established a social representation. The central core consisted of the following terms: planning, knowledge, and management; the first periphery: organization; the contrast zone: territorialization and humanization; and the second periphery: commitment, reality, patience, and goals. Evocations suggested that the internship consisted of activities that equipped the professionals with the necessary skills and abilities for the new professional profile. The social representation of students in the Dentistry course included in an environmental internship in Primary Health Care is marked by terms typical of implementing knowledge in the Brazilian public health system and shows the course’s curricular programs’ contents.

The approximate solution of one dimensional stochastic evolution equations by meshless methods

In this article, we develop an iterative scheme based on the meshless methods to simulate the solution of one dimensional stochastic evolution equations using radial basis function (RBF) interpolation under the concept of Gaussian random field simulation. We use regularized Kansa collocation to approximate the mean solution at space and the time component is discretized by the global $ theta $-weighted method. Karhunen-lo`{e}ve expansion is employed for simulating the Gaussian random field. Statistical tools for numerical analysis are standard deviation, absolute error, and root mean square. In this work, we solve two major problems for showing the convergence, and stability of the presented method on two problems. The first problem is the semilinear stochastic evolution problem, and the second one is stochastic advection-diffusion model with different control values.
Yield Attributing Characters and Yield of Mungbean Crop as Affected by Phosphorus, PSB, and Vermicompost

Pulses cover a vast area of the Bundelkhand (UP) and Mungbean is prominent among the pulse crops and it is grown on a larger scale using local varieties entirely in dryland conditions and on residual soil moisture and fertility. In Bundelkhand, farmers grow the crops traditionally and without considering the scientific recommendations. Inorganic fertilizers (synthetic) are an important source of plant nutrients but their continuous and injudicious use posing health and environmental complications. Minimum use of inorganic sources of nutrients and rely on integrated nutrient management is the way to tackle the health and environmental issues due to imbalance and excessive use of inorganic nutrients. Phosphorus, PSB and vermicompost are found to play very important role in boosting the yield of legume crops. This research is, therefore, taken into account to evaluate the response of Mungbean crop to phosphorus, PSB, and vermicompost. The leguminous crops require more phosphorus as it is required for energy transformation in nodules. Phosphate solubilizing bacteria (PSB) is assumed to have greater significance because it helps to convert insoluble organic phosphates into simple and soluble forms. Vermicompost is a better and rich source of N, P, K, and micronutrients. Besides, containing a good proportion of exchangeable Ca, Mg, Na, etc., vermicompost enhances organic carbon to the soil and meagerly helps to release of nutrients and in turn uptake is improved. A field experiment was performed during Kharif season, 2019 at Agriculture Farm of Banda University of Agriculture and Technology Banda, Uttar Pradesh, India. Results of the study reveals that the basal applications of 75 kg DAP, 5 t Vermicompost (VC) ha-1 and seed treated by Phosphate Solubilizing Bacteria (PSB) led to a significant increase in yield attributing characters and yield and gave by 22.57% more yield advantage than the farmer’s practice. However, the application of higher doses of DAP with VC and PSB gave luxuriant growth to the crop rather than increased yield.
Chronic nonbacterial osteomyelitis: report of thirteen cases

Introduction: Chronic Nonbacterial Osteomyelitis (CNO), also known as Chronic Recurrent Multifocal Osteomyelitis (CRMO), is a rare autoinflammatory bone disorder that causes multifocal or unifocal aseptic lytic lesions in bone biopsy and is characterized by periodic exacerbations and remissions of sterile osteomyelitis. The aim of this report was to describe clinical features, subsidiary exams, treatment and outcome of thirteen cases of CNO followed in a tertiary center in Brazil. Methods: We carried out a single-center retrospective descriptive review of clinical records, including thirteen children and adolescents with CNO followed between 2010 and 2020 in our tertiary service in Brazil. Medical records were reviewed in order to collect data about clinical presentation, inflammatory markers, radiological and histological findings, treatment and outcome.The diagnosis of CNO was based on the Bristol diagnostic criteria for CRMO. Results: Thirteen patients were included in this study, of whom 46% were female. Median of current age and of follow-up time were 11 years (range 8.5-20.4) and 40 months (range 9-123), respectively. Median age at disease onset was 8.1 years (range 0.8–15.3) and median age at diagnosis was 11 years (range 7-16.1). The most affected sites were metaphysis and diaphysis of long bones. Median number of initially affected bones was 4.0 (range 1-7). Five patients had recurrences. All patients had increased acute phase reactants at disease onset. All patients had at least one of the characteristic findings on MRI (lytic lesions, osteitis, hyperostosis and periostitis). Five patients received systemic glucocorticoids, eight received methotrexate and seven received bisphosphonates (alendronate). Conclusion: The awareness of the features of CNO is important for an early diagnosis and may avoid unnecessary diagnostic procedures and prolonged antibiotic therapies.
Automatic Text Summarization for A thesis submitted for the Degree of Master of University of Colombo School of Computing

With the rapid development of information and communication technology, people are surrounded with vast amounts of information albeit with less and less time or ability to make sense of it. The field of automatic summarization which has been in existence since the 1950’s is anticipated to find solutions to this issue. With the adaptation of Unicode technology in 2004, the Sinhala language began to appear in computers rapidly and Sinhala language users also began to experience the above issue. This research on Automatic Text Summarization in Sinhala is carried out to find the possible approaches to address the above issue with the minimum linguistic resources. The field of automatic text summarization began with some classical approaches which attempted to indentify the most salient information of an article using some thematic features. This research was intended to indentify such features for the Sinhala language with the most suitable approach to define each of these features for achieving accurate summaries. In order to benefit from all these features, this research proposes a best possible linear combination of identified features. The proposed method was evaluated by comparing the machine generated and human extracted summaries based on the primary assumption that the human summaries are perfect. Results show that the sentence location feature is the best individual feature for extracting most informative sentences from Sinhala articles while the linear combination of keyword feature, title words feature and the sentence location feature giving the best performance for a summarizer. Results revealed some equations to define the flow of information over a Sinhala article which can be used in many such applications. Further, this research provides a benchmark for future research on Sinhala automatic text summarization.
