Kahoot! App: An Interactive Tool to Enhance the English Participation of Grade 7 Students

This study is aimed at improving the participation of 30 Grade 7 students during the Academic Year 2021-2022 through the Kahoot! App. Kahoot! is a game-based student-response system that focuses on engaging the students in the classroom. Through class observations and interviews, it was found that students were rarely volunteering to answer questions and contribute to the discussion because of the traditional tools used by the teacher. To further validate the researchers’ observations, the respondents were given a pre-survey checklist as well as a post- post-survey checklist. This was to determine their extent of participation before and after the employment of the intervention. Results showed that the mean score of the respondents in their pre-survey was 1.79 or Strongly Disagree, while in their post-survey, it was 4.41 or Strongly Agree which means that there was a mean difference of 2.63. Also, the t-value of -37.51 means that the pre-survey checklist obtained a lower result than the post-survey checklist. This is attributed to the fact that the students favored and preferred Kahoot! App than Google Form. In addition, the p-value of 0.000 is less than the .01 level of significance which further validates that there is a significant difference of the pre-survey and the post-survey. This implies that the intervention of this research proved to improve the participation of the students in English. Thus, the intervention of this study is highly recommended for teachers to use in facilitating assessment activities in online setting because of the its engaging features like colorful backgrounds, pictures, interesting graphics, and immediate feedback, which motivate the students to participate.

TEACHING NARRATIVE TEXT THROUGHMIND MAPPING TECHNIQUE

This research focused on teaching narrative text through mind mapping technique. The objectives of this research were to know and describe the process of teaching narrative writing using mind mapping. The data of this study were qualitative and quantitative. The qualitative data were obtained by observing the teaching-learning process during the implementation of the actions and interviewing the students and the collaborator about the implemented actions. The qualitative data were in the forms of field notes and interview transcripts. Meanwhile, the quantitative data were gained by assessing the students’ writing skill through the pre-test and the post-test. Therefore, the quantitative data were in the form of students’ writing scores in the pre-test and the post-test. The results of this study showed that the use of the mind mapping was effective to improve the students’ writing skill. The use of colorful pictures of mind mapping in the BKOF and MOT stages was effective to make the students more enthusiastic in the writing activities. The writers found that the student’s problems in writing were that the students were confused to develop their ideas because they did not have many vocabularies. Furthermore, the students had problems in matters of capitalization, punctuation, grammatical error, and organization. They also needed too much time to finish their writing.

Development of acerola (Malpighia emarginata DC.) fruit jelly with addition of red propolis: bioactive compounds and antioxidant activity / Desenvolvimento de geleia de fruta de acerola (Malpighia emarginata DC.) com adição de própolis vermelha: compostos bioativos e atividade antioxidante

Jelly is a product obtained by cooking whole fruit or its pieces or fruit pulp or juice with sugar and water, and concentrating the mixture to a gelatinous consistency. The objective of this work was to elaborate acerola jelly with the addition of the red propolis extract and to evaluate the product by determining physicochemical and bioactive (total phenolic and flavonoids, anthocyanin contents) compounds composition supported by its antioxidant activity (DPPH, ABTS, FRAP and ORAC) and sensorial analysis. Four jelly formulations were prepared with variations in the red própolis contents: T1 (no red própolis addition), T2 (1.5% addition of the red própolis), T3 (3.0% addition of the red própolis), T4 (4.5% addition of the red própolis). The Ext. 1 (Extraction 1 was used where the solvents methanol 80% and acetone 70% were used) were the best for the tests of antioxidant activities DPPH, ABTS AND ORAC of jellies with the addition of red propolis extract. For FRAP, the jelly presented the highest averages for the treatments of (Ext. 2 Where 95% ethanol,) where it used ethanol as a solvent. The organic acids which were detected revealed the presence of oxalic ac-id (3.02 mg/mL to 3.69 mg/mL), quinic acid (28.53 mg/mL to 39.67 mg/mL), L-ascorbic acid (3.70mg/mL to 4.35mg/mL), citric acid (0.16 mg/mL to 0.52 mg/mL), showing significant difference (p≤0.05) between them. Phenolic compounds identified were L-ascorbic acid, protocatechuic acidrut-in: difference (p≤0.05) between them. Phenolic compounds identified were: quecertin3glucoside, epicatechin, epigallocatechingallate, epicatechingallat2 hydroxycinnamic acid, daidzein), showed higher results for the extracts ob-tained from treatment 2 where ethanol was used as solvent. 2-hydroxycinnamic acid, daidzein), showed higher results for the extracts ob-tained from treatment 2 where ethanol was used as solvent. Color, texture and physicochemical characteristics (moisture, total soluble solids - TSS, pH, titratable acidity - ATT, protein, lipid, carbohydrate) were determined. Sensory analysis was conducted only after approval by the Research Ethics Committee (CEP), Federal University of Sergipe (Opinion number: 3.769.247). Untrained judges were subjected to sensory testing where they responded to the attributes on hedonic scales evaluating appearance, color, aroma, viscosity, flavor, sweetness and overall impression. The results showed the highest averages for T2 with the addition of 1.5% propolis extract compared to standard jelly. For Acceptance Index, all treatments scored above 70%, which signifies products acceptability by consumers.

Identification of fountain pen ink properties which determine the amount put on paper during handwriting

Handwriting with a modern fountain pen is an unique experience in present time, far beyond the pure necessity of making notes. The differences to ballpoint pens, rollerballs or pencils are in the tactual perception of the nib gliding over the paper surface and in the visual impression of a freshly drawn ink line with all the colour impressions and changing light reflections when a wet line dries and reveals either shading or sheen. This subjective impression of the wet line is commonly described as ink wetness and a lot is discussed and speculated about why one ink writes „wet“ and another „dry“. While such a subjective impression can not, the amount of ink put onto the paper can be measured quantitatively. To that end, a number of commercially available fountain pen inks were used to draw lines of a certain length and the amount of ink laid down on the paper was measured. These ink consumption data were correlated to the physical and chemical properties by a principal component analysis. The most significant outcome was the primary dependence of „ink wetness“ on surface tension, followed by viscosity and conductivity with unexpected and partly counter-intuitive correlations.

Effects of incidental reminders on prospective memory in children.

Prospective memory (PM) involves remembering to carry out intended actions in the future (e.g., posting a letter on the way to school or passing on a message) and is important for children's independent functioning in daily life. This study examined, for the first time, the effects of incidental reminder cues on children's PM. Five- and 7-year-old children (n = 160, 50% female, predominantly White from lower-middle- to middle-class families) had to remember to put cards with a picture of a dog into a box (placed behind the child) every time they finished working on an activity book with a line drawing on each page (activity-based PM task). Additionally, the picture presented on the last page of each activity book was manipulated to examine the role of incidental reminders on PM. Results showed that 7-year-old children significantly outperformed 5-year-olds on the PM task despite age equivalence of performance on the ongoing visual search task. For both age groups, an incidental reminder (a line drawing of a dog) that was similar to the target of the PM task (a card with a color picture of a dog) significantly improved PM compared to the no-reminder condition (a line drawing of a flower), while reminders related to the PM action (a line drawing of a box) or semantically related to the target of the PM task (a line drawing of a cat) were not effective. These findings have important practical and theoretical implications and open up interesting avenues for future research. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Active Learning Activities in a Collaborative Teacher Setting in Colours, Design and Visualisation

We present our experience with developing active learning activities in a collaborative teacher setting, along with guidelines for teachers to create them. We focus on developing learner skills in colours, design, and visualisation. Typically, teachers create content before considering learning tasks. In contrast, we develop them concurrently. In addition, teaching in a collaborative setting (where many teachers deliver or produce content) brings its own set of challenges. We developed and used a set of processes to help guide teachers to deliver appropriate learning activities within a theme that appear similarly structured and can be categorised and searched in a consistent way. Our presentation and experience of using these guidelines can act as a blueprint for others to follow and apply. We describe many of the learning activities we created and discuss how we delivered them in a bilingual (English, Welsh) setting. Delivering the learning activities within a theme (in our case, colours) means that it is possible to integrate a range of learning outcomes. Lessons can focus on, for instance, skill development in mathematics, physics, computer graphics, art, design, computer programming, and critical thought. Furthermore, colour is a topic that can motivate: it sparks curiosity and creativity, and people can learn to create their own colourful pictures, while learning and developing computing skills.

Automatic Gray Image Coloring Method Based on Convolutional Network.

Image coloring is a time-consuming and laborious work. For a work, color collocation is an important factor to determine its quality. Therefore, automatic image coloring is a topic with great research significance and application value. With the development of computer hardware, deep learning technology has achieved satisfactory results in the field of automatic coloring. According to the source of color information, this paper can divide automatic coloring methods into three types: image coloring based on prior knowledge, image coloring based on reference pictures, and interactive coloring. The coloring method can meet the needs of most users, but there are disadvantages such as users cannot get the multiple objects in a picture of different reference graph coloring. Aiming at this problem, based on the instance of color image segmentation and image fusion technology, the use of deep learning is proposed to implement regional mixed color more and master the method. It can be divided into foreground color based on reference picture and background color based on prior knowledge. In order to identify multiple objects and background areas in the image and fuse the final coloring results together, a method of image coloring based on CNN is proposed in this paper. Firstly, CNN is used to extract their semantic information, respectively. According to the extractive semantic information, the color of the designated area of the reference image is transferred to the designated area of the grayscale image. During the transformation, images combined with semantic information are input into CNN model to obtain the content feature map of grayscale image and the style feature map of reference image. Then, a random noise map is iterated to make the noise map approach the content feature map as a whole and the specific target region approach the designated area of the style feature map. Experimental results show that the proposed method has good effect on image coloring and has great advantages in network volume and coloring effect.

A Color-Picture Version of Boston Naming Test Outperformed the Black-and-White Version in Discriminating Amnestic Mild Cognitive Impairment and Mild Alzheimer's Disease.

Despite the ubiquity of the Boston naming test (BNT) in clinical practice and research, concerns have been expressed about its poor quality pictures, insufficient psychometric properties, and cultural bias in non-English language backgrounds. We modified the black-and-white BNT with a set of color pictures since color effects have been suggested to improve naming accuracy in the visual naming test. This study aimed to examine and compare the reliability and validity of the color-picture version of BNT (CP-BNT) and the black-and-white version of BNT (BW-BNT) to differentiate amnestic mild cognitive impairment (aMCI) or mild Alzheimer's disease (AD) from the cognitive normals. This study included two subgroups, and each subgroup had 101 normal controls, 51 aMCI, and 52 mild AD. One subgroup undertook BW-BNT and the other conducted CP-BNT. The reliability, convergent and discriminant validity, and the diagnostic accuracy of two versions of BNT were evaluated. The CP-BNT showed a greater area under the curve (AUC) than the BW-BNT for aMCI (80.3 vs.s 69.4%) and mild AD (93.5 vs. 77.6%). The CP-BNT also demonstrated better convergent validity with CDR global scores and better reliability (Cronbach's coefficient 0.66 for the CP-BNT vs. 0.55 for the BW-BNT). At the optimal cutoff value of spontaneous naming, the CP-BNT demonstrated improved sensitivity and specificity for differentiating mild AD from NC with a higher positive predictive value, negative predictive value, and lower false-positive rate. Compared with BW-BNT, CP-BNT is a more reliable and valid test to assess cognitive and naming impairment.

Comparison of Dy3+-doped barium borate and lithium aluminoborate glass

The optical properties of Dy3+ in barium borate (BaB) glass are compared to those of Dy3+ in lithium aluminoborate (LiAlB) glass. Sample series with varying modifier-to-former ratio and different Dy3+ concentration are analyzed for their optical absorption, external quantum efficiency, luminescence yield, and chromaticity. The photoluminescence (PL) spectra are dominated by two emission bands in the visible spectral range, namely at 483 nm and 575 nm. The BaB as well as the LiAlB glass series show a luminescence quenching upon increasing the Dy3+ concentration, though the optical absorption increases linearly. For both, a change in the modifier-to-former ratio from 1 : 2 to 1 : 4 leads to an increase in luminescence yield with the maximum at a Dy3+ content of (0.2–0.3) at.%. Compared to LiAlB glass, the absorption coefficient as well as the PL quantum efficiency of Dy3+ are slightly lower in BaB glass. The colour impression of the BaB and the LiAlB glass series are very similar; it changes with the modifier-to-former ratio as well as the Dy3+ concentration. The analysis of the PL lifetime measurements on the basis of the Förster model yield an intrinsic Dy3+ lifetime of slightly above 900 μs. For a Dy3+ content of 0.5 at.%. and higher, the energy transfer between neighbouring Dy3+ ions is noticably enhanced.

Structural color printing via polymer-assisted photochemical deposition

Structural color printings have broad applications due to their advantages of long-term sustainability, eco-friendly manufacturing, and ultra-high resolution. However, most of them require costly and time-consuming fabrication processes from nanolithography to vacuum deposition and etching. Here, we demonstrate a new color printing technology based on polymer-assisted photochemical metal deposition (PPD), a room temperature, ambient, and additive manufacturing process without requiring heating, vacuum deposition or etching. The PPD-printed silver films comprise densely aggregated silver nanoparticles filled with a small amount (estimated <20% volume) of polymers, producing a smooth surface (roughness 2.5 nm) even better than vacuum-deposited silver films (roughness 2.8 nm) at ~4 nm thickness. Further, the printed composite films have a much larger effective refractive index n (~1.90) and a smaller extinction coefficient k (~0.92) than PVD ones in the visible wavelength range (400 to 800 nm), therefore modulating the surface reflection and the phase accumulation. The capability of PPD in printing both ultra-thin (~5 nm) composite films and highly reflective thicker film greatly benefit the design and construction of multilayered Fabry–Perot (FP) cavity structures to exhibit vivid and saturated colors. We demonstrated programmed printing of complex pictures of different color schemes at a high spatial resolution of ~6.5 μm by three-dimensionally modulating the top composite film geometries and dielectric spacer thicknesses (75 to 200 nm). Finally, PPD-based color picture printing is demonstrated on a wide range of substrates, including glass, PDMS, and plastic, proving its broad potential in future applications from security labeling to color displays.

Comparison of color accuracy and picture quality of digital SLR, point and shoot and mobile cameras used for dental intraoral photography – A pilot study

The present study aimed to compare the picture quality and color accuracy of three cameras, namely, Point and shoot, DSLR and mobile cameras, and determine the most suitable camera for dental photography (intra-orally and for casts). A computer program, namely, NRM (No-Reference matrix BRISQUE), was used to evaluate the quality of the photos taken by three cameras. Further, color accuracy was determined by computation of total color difference (ΔE) by identifying the L∗a∗b∗ values.The ANOVA (Kruskal-Wallis) analysis was done to assess the difference in the quality of cast photos, and it showed a statistically significant difference (p < 0.05) between the cameras. The post hoc analysis showed the NRM value of Point and shoot (18.93 ± 2.04) better than the Mobile phone (20.59 ± 2.65). However, no statistically significant difference was obtained while assessing the picture quality of the intraoral photographs using One-Way ANOVA (Fisher's) (P = 0.05).Evaluation of total color difference (ΔE) showed fewer differences between the DSLR and the Point and shoot than the mobile camera. There was no statistically significant difference in ΔE value in the participant photographs. The L in the LAB values of both the cast and the participant photograph showed a similar result, with the mobile phone showing a lighter value than the other two cameras. The B value in the participant photos showed a significant difference between the mobile and the Point and shoot cameras.The quality of Point and shoot, DSLR, and mobile cameras were equally good for taking pictures of any external surface, but the mobile camera offered more brightness and appeared more yellow. On the other hand, the quality was similar for intraoral images with mobile and Point and shoot cameras, although color accuracy was better with Point and shoot and DSLR cameras.

The Doll. By Nhung N. Tran-Davies and Illustrated by Ravy Puth

This book is about a refugee who comes to Canada with her mother and six siblings as a young child. When she first arrives, a girl around her age gives her a doll. The refugee who receives the doll grows up to become a doctor and sees that another group of refugees is coming to Canada. Remembering her own experience, she goes to the airport to give the doll to another little girl arriving in Canada. This book shows young children about the importance of kindness and welcome. By paying an act of kindness forward, the author shows how human beings are connected. Illustrated with colourful pictures, the book is written in a poetic style. The repetition of keywords and events would appeal to children in early primary grades. However, the vocabulary and indirect telling of key events are more appropriate for an...

Development of a Finite Element Method and Its Application in a CAD

The presented review of existing domestic and foreign CAD systems showed that the use of FEM in their structure remains quite relevant before other methods in the speed of calculations, sufficient accuracy and software implementation in the CAD structure. To solve the problems of mechanics of elastomers and composites based on them, an over-view of the developed domestic software MIRELA+ is presented in more detail. This complex solves many problems of solid mechanics: it has a special focus on solving problems of dissipative heating, parameters of fracture mechanics of massive elastomeric structural elements and thin-layer rubber-metal elements with cracks with changing physical, mechanical and thermophysical parameters under cyclic deformation. Not many of the domestic programs can implement this, and licenses for foreign programs cost tens of thousands of dollars.This paper also presents methods of discretization by finite elements and an algorithm for constructing a system of re-solving equations used in MIRELA+, expressions for determining the components of the coordinate transformation tensor, the strain tensor at the FE centers in a Cartesian coordinate system. Examples of visual representation in a three-dimensional image using a color picture are given, where each shade or color corresponds to a certain range of numerical values of the corresponding function.

From PKU Online Lessons for Dietetics Students to the PKU Sandwiches Album

The purpose of the manuscript is to present to academic teachers, doctors and nutritionists how practical online classes with dietetics students can be used to develop ready-made tools at work and for the education of phenylketonuria (PKU) patients and their caregivers/parents. During online classes in 2020, as part of the subject—diet therapy of metabolic blocks, 53 students prepared PKU sandwiches at home. Each PKU sandwich has a calculated nutritional value, and phenylalanine exchanger content, but does not include low-protein bread. The selection of a particular type of PKU bread depends solely on the PKU patient, hence it was deliberately not included in the calculations. The sandwiches, made by students and assessed by academic teachers, will be published with the following title “The PKU Sandwiches Album”. The Album with more than 400 colorful pictures of PKU sandwiches, will be expected to inspire patients and help them add appeal to their diet, enriching it with new tastes, at the same time facilitating the memorizing process of ingredients, thanks to visualization and presented calculations, and motivating them to comply with strict dietary recommendation. The same nutritional calculations and ideas for sandwiches, with the use of different bread, e.g., gluten-free, may be useful in other diseases, such as celiac disease.

APLIKASI DIGITAL MARKETING UNTUK MENINGKATKAN OMZET PENJUALAN PRODUK KERAMIK HANDMADE NARUNA

The ceramic products discussed in this paper are hand-processed ceramic tableware with a competitive advantage in using the glazing technique at Naruna Ceramic Studio (NCS), Salatiga, Central Java, Indonesia. This technique is a coloring method after the first combustion of a ceramic kiln that can give a characteristic to the product giving an attractive and elegant color impression that can increase sales turnover and competitiveness of NCS compared to similar. The COVID-19 pandemic that continues to exist in Indonesia forces the number of customer sales to not be able to interact directly with NCS, so it is necessary to change a new marketing strategy carried out by NCS to increase turnover. The digital marketing method in this paper is applied by the author and NCS to market handmade ceramic tableware products with a finishing process using the glazing technique. The Digital Marketing System applied by NCS and researchers is to build an advertising platform that can influence consumer behavior so that it can make a significant contribution to increasing the turnover of this ceramic product seller. The ads that posted on Facebook, Instagram, YouTube, TikTok, and Website will be done will be based on the landing page which ends in the marketplace (Shopee, Tokopedia) and the WhatsApp application which is managed by NCS customer service. The final results up to October 2020 showed an increase in turnover of 65% after the implementation of this DM was implemented

Revisiting Dr. Seuss’s The Lorax as Stimulus for Sustainable Development Goal 15

Dr. Seuss’ vivid picture book <em>The Lorax</em> (1971) depicts the story of how the Street of The Lifted Lorax (setting) came to be. There is an air of mystery about the place as we wonder how the Truffula forest, once teeming with wildlife and the dominant presence of the Lorax (the titular character), grew into such disrepair. The disappearance of the Lorax is a puzzle which is solved as events within the story unfold. With the use of colorful pictures that visually appeal to the young audience, the book attempts to create a sense of responsible use of resources and sustainable development around the imagined world of Truffula trees. Through its perusal, Seuss evokes a sense of eco consciousness in the readers as they empathize with the displacement and helplessness felt by the protagonists. The text, while managing to convey the gravity of the situation, reiterates the urgence to ‘promote sustainable use of terrestrial ecosystems’ as per the Sustainable Development Goal 15. This paper aims to discuss how <em>The Lorax</em> seeks to challenge the anthropocentric point of view by replacing it with a deep ecological stance. This will be done by critically examining the role of the protagonists and analyzing how key incidents of the text compare to the real-life developments and contribute to the present-day scenario, keeping Nature as the focus.

Perovskite Solar Cells with Vivid, Angle‐Invariant, and Customizable Inkjet‐Printed Colorization for Building‐Integrated Photovoltaics

The steadily growing market share of building‐integrated photovoltaics (BIPVs) places the aesthetics of solar modules in the focus of research and development. In this work, a colorization method based on inkjet‐printed reflective pigments is adapted for the emerging perovskite photovoltaics. Herein, not only excellent control of color impression, brightness, and pattern is demonstrated, but also angle invariant color perception, which makes the presented approach stand out among the many published colorization strategies for perovskite solar cells (PSCs). Compared to uncolored reference solar cells, bright magenta and yellow PSCs display a remarkable relative power conversion efficiency (PCE) of up to 65% and more than 11% absolute PCE. Moreover, PSCs with more BIPV‐relevant coloring patterns such as a mimic of a marble or corten steel surfaces are demonstrated. The colorization method presented is inexpensive and ready for scalable solar module production. To demonstrate the scalability of the proposed concept, a small‐area perovskite solar module (4 cm2 aperture area) in white marble optics exhibiting a PCE of almost 14% as a potential application is presented.

V. Nabokov’s Colors: Meanings and Methods of Creation

Dictionaries of color designations give an idea of a color picture of the world belonging to the investigated author. They are a segment of the general panorama of the author’s poetic world. These dictionaries usually represent the alphabetical order of tokens denoting color, indicating the number of tokens, as&#x0D; well as quotes from text fragments with links to the source. Vladimir Nabokov created and over the years maintained the myth of his amazing relationship with color, so the study of his color picture of the world is a special case. The basis of the research is created by the authors of the article. It is «Dic-&#x0D; tionary of Color Meanings in the Lyrics of Vladimir Nabokov». The principle of its compilation is based on the «color alphabet» set forth by the writer in two autobiographical versions («Other Shores» and «Speak, Memory: An Autobiog-&#x0D; raphy Revisited», as well as in the novel «The Gift», where Nabokov actually presented a reference dictionary of his own color terms and gave color characteristics the form of a dictionary interpretation. Special attention in the article is paid&#x0D; to the most extravagant ways of endowing color meanings. An illustration of these methods is reconstruction of the meanings of the following author’s color designations: «Gallic gloss», «Smolensk porridge» and «gutta-percha» – «clyster» –&#x0D; «sienne brûl, sepia».

Color ghost imaging through the scattering media based on A-cGAN.

Ghost imaging plays an important role in the field of optical imaging. To realize color ghost imaging through the scattering media, we propose a deep learning method with high generation ability. Through our method, we can efficiently reconstruct color images with rich details, in line with human perception and close to the target color pictures. Experimental results show that our method can image through the scattering media with different scattering intensities and achieve good results even at a sampling rate of 0.1.

Let’s Get Personal, Let’s Get Physical: Approaching the Bodily Self in Clinical Interactions

Medicine usually looks at the body as a biochemical and physical apparatus – from a distant third-person perspective, with fragmented, reductionist positions, unidirectional causal models, and highly selective foci. Even psychiatrists and psychotherapists focus more and more on the brain as an organ, look at genes and colourful pictures. And just as biomedical medicine stares at physical and chemical facts and ignores the person, one could say that psychotherapy stares at personality, cognition, and behaviour and ignores the body. But the lowlands where being-a-person and having-a-body meetmatter a lot for becoming ill, staying, and getting well. What attitudes and what approaches can help us understand the bodily self? After very briefly summarizing current understandings of embodiment and enactivism, we will suggest some practical consequences for everyday clinical diagnostics.
