Authors: Aghigh Arash , Preston Samuel E. J. , Jargot Gaëtan , Ibrahim Heide , Del Rincón Sonia V , Légaré François
Published: April 2023

Tumors, their microenvironment, and the mechanisms by which collagen morphology changes throughout cancer progression have recently been a topic of interest. Second harmonic generation (SHG) and polarization second harmonic (P-SHG) microscopy are label-free, hallmark methods that can highlight this alteration in the extracellular matrix (ECM). This article uses automated sample scanning SHG and P-SHG microscopy to investigate ECM deposition associated with tumors residing in the mammary gland. We show two different analysis approaches using the acquired images to distinguish collagen fibrillar orientation changes in the ECM. Lastly, we apply a supervised deep-learning model to classify naïve and tumor-bearing mammary gland SHG images. We benchmark the trained model using transfer learning with the well-known MobileNetV2 architecture. By fine-tuning the different parameters of these models, we show a trained deep-learning model that suits such a small dataset with 73% accuracy.
Safe and efficient dental cavity preparation by applying a gradient-in-power approach from Er,Cr:YSGG laser: an in-vitro study
Authors: Al-Shammari Alyamama MH. , Salman Ansam M. , Al-janabi Abdulhadi
Published: April 2023

In this in-vitro study, a gradient-in-power approach aims to ensure no temperature elevation beyond the necrosis limit (5.5 °C) during laser cavity preparation of dental hard tissues. The applied optimal Er,Cr:YSGG laser parameters were: 20 Hz pulse repetition rates (prr), average powers at a maximum of 5.5 W for enamel switched to a maximum of 3.5 W for dentine surface specimens. A fabricated fast-response all-optical fiber sensor was used to monitor temperature change simultaneously. A scanning electron microscope (SEM) and a Fourier transform infrared (FTIR) spectroscopy were used to assess the irradiated surfaces. Holes of 500 µm in depth were obtained with no morphological and chemical alterations.
Designing microwave photonic signal processors based on microcombs
Authors: Moss David
Published: April 2023

Microwave photonic (MWP) transversal signal processors offer a compelling solution for realizing versatile high-speed information processing by combining the advantages of reconfigurable electrical digital signal processing and high-bandwidth photonic processing. With the capability of generating a number of discrete wavelengths from micro-scale resonators, optical microcombs are powerful multi-wavelength sources for implementing MWP transversal signal processors with significantly reduced size, power consumption, and complexity. By using microcomb-based MWP transversal signal processors, a diverse range of signal processing functions have been demonstrated recently. In this paper we provide a detailed analysis for the errors induced by experimental imperfections processors. First, we investigate the errors arising from different sources including imperfections in the microcombs, the chirp of electro-optic modulators, chromatic dispersion of the dispersive module, shaping errors of the optical spectral shapers, and noise of the photodetector. Next, we provide a global picture quantifying the impact of error sources on the overall system performance. Finally, we introduce feedback control to compensate the errors caused by experimental imperfections, achieving significantly improved accuracy. These results provide a guide for optimizing the accuracy of microcomb-based MWP transversal signal processors.
Collation of a century of soil invertebrate abundance data suggests long-term declines in earthworms but not tipulids
Authors: Barnes Ailidh E. , Robinson Robert A. , Pearce-Higgins James W.
Published: April 2023

Large-scale declines in terrestrial insects have been reported over much of Europe and across the world, however, population change assessments of other key invertebrate groups, such as soil invertebrates, have been largely neglected through a lack of available monitoring data. This study collates historic data from previously published studies to assess whether it is possible to infer previously undocumented long-term changes in soil invertebrate abundance. Earthworm and tipulid data were collated from over 100 studies across the UK, spanning almost 100 years. Analyses suggested long-term declines in earthworm abundance of between 1.6 to 2.1% per annum, equivalent to a 33% to 41% decline over 25 years. These appeared greatest in broadleaved woodlands and farmland habitats, and were greater in pasture than arable farmland. Significant differences in earthworm abundance between habitats varied between models but appeared to be highest in urban greenspaces and agricultural pasture. More limited data were available on tipulid abundance, which showed no significant change over time or variation between enclosed farmland and unenclosed habitats. Declines in earthworm populations could be contributing to overall declines in ecosystem function and biodiversity as they are vital for a range of ecosystem services and are keystone prey for many vertebrate species. If robust, our results identify a previously undetected biodiversity decline that would be a significant conservation and economic issue in the UK, and if replicated elsewhere, internationally. We highlight the need for long-term and large-scale soil invertebrate monitoring, which potentially could be carried out by citizen/community scientists.
Applicability of Hubbert model to global mining industry: Interpretations and insights
Authors: Riondet Lucas , Suchet Daniel , Vidal Olivier , Halloy José
Published: April 2023

The Hubert’s model has been introduced in 1956 as a phenomenological description of the time evolution of US and world oil fields production. It has since then acquired a vast notoriety as a conceptual approach to resource depletion. It is often invoked nowadays in the context of the energy transition to question the limitations induced by the finitude of mineral stocks. Yet, its validity is often controversial despite its popularity. This paper offers a pedagogical introduction to the model, assesses its ability to describe the current evolution of 20 mining elements, and discusses the nature and robustness of conclusions drawn from Hubbert’s model considered either as a forecast or as a foresight tool. We also propose a novel way to represent graphically these conclusions as a “Hubbert’s map” which offers direct visualization of their main features.

Authors: Widayanti Costrie Ganes , Dewi Kartika Sari
Published: April 2023

COVID-19 has caused tremendous challenges for people with disabilities, such as those with vision loss, which affect their daily lives. This qualitative study was undertaken on six participants with vision loss to understand the challenges they had when implementing health protocols in the prevention of COVID-19. Open coding, axial coding, and selective coding were conducted to analyse the data. The study also pointed out that participants experienced physical, psychological, economic and social challenges in exercising the health protocols of COVID-19, such as in implementing physical distancing and wearing face masks. The participants felt alienated because of their limited direct interactions and experienced loss of income. Online learning caused minimize learning experiences and accessibility problems. These challenges potentially widen discrimination and inequality practices for people with disabilities in Indonesia with COVID-19 mitigation preparedness plan.
COVID-19 telah menimbulkan tantangan bagi penyandang disabilitas, termasuk mereka dengan hambatan visual, yang mempengaruhi kehidupan mereka sehari-hari. Penelitian ini merupakan studi kualitatif yang bertujuan untuk memahami tantangan dan strategi yang dilakukan partisipan dengan hambatan visual berkaitan dengan melaksanakan kebijakan protokol kesehatan. Open coding, axial coding, dan selective coding dilakukan untuk menganalisis data. Hasil penelitian menunjukkan bahwa partisipan mengalami tantangan fisik, psikologis, sosial, dan ekonomi selama menjalankan protokol kesehatan COVID-19, yang meliputi penggunaan masker dan menjaga jarak. Partisipan menilai adanya pembatasan sosial menimbulkan perasaan terasing karena interaksi tidak dapat dilakukan secara leluasa dan berkurangnya bahkan hilangnya pendapatan. Pembelajaran online mengakibatkan terbatasnya pengalaman belajar dan akses terhadap materi pembelajaran. Tantangan ini berpotensi memperkuat praktik diskriminasi, yang telah terjadi sebelumnya sehingga semakin memperlebar praktik eksklusi bagi penyandang disabilitas di Indonesia, terutama berkaitan dengan manajemen mitigasi penanganan bencana COVID-19.
Perempuan dengan Disabilitas Merespon Covid-19
Authors: Ro'fah Ro'fah
Published: April 2023

This research shows that --reinforcing existing research-- women with disabilities experience quite complex obstacles and impacts of Covid 19. The intersection between disability and gender creates the seriousness and complexity of the impacts experienced. The economic and social impact faced by women with disabilities is strengthened by their already vulnerable position economically and socially: lack of accessibility, social protection policies that are not inclusive and cultural factors still stigmatizing. However, in contrast to the assumptions about powerlessness and dependency, these women are strong figures whose resilience has been built. The Bantul earthquake that made them disabled has shaped them as resilient women who see the impact of Covid as a lighter disaster. These women even see Covid as a medium to form a positive identity and challenge stigma, prejudice, and social construction about the inability of women with disabilities to become mothers and wives.
Penelitian ini menunjukkan bahwa --menguatkan penelitian yang sudah ada-- perempuan dengan disabilitas mengalami hambatan dan dampak Covid 19 yang cukup kompleks. Persinggungan antara disabilitas dan gender melahirkan keseriusan dan kompleksitas dampak yang dialami. Dampak ekonomi dan sosial yang dihadapi perempuan penyandang disabilitas dikuatkan dengan posisi mereka yang sudah rentan secara ekonomi dan sosial:  minimnya aksesibilitas, kebijakan perlindungan sosial yang tidak inklusif dan juga faktor kultural yang masih menstigmasi. Namun, berbeda dengan asumsi tentang ketidakberdayaan dan ketergantungan, perempuan perempuan ini adalah sosok kuat yang sudah terbangun resiliensinya. Gempa Bantul yang menjadikan mereka penyandang disabilitas telah membentuk mereka sebagai perempuan reselien yang melihat dampak Covid sebagai musibah yang lebih ringan. Perempuan perempuan ini bahkan melihat Covid sebagai media mereka membentuk identitas positif dan menggugat stigma dan prejudice dan konstruksi sosial  tentang ketidakmampuan perempuan disabilitas menjadi ibu dan istri.
Three Strikes and You’re Out: The Demographics of Indiana’s Habitual Offender Law
Authors: Thuesen Isaac
Published: April 2023

Decades of research have shown that racial minorities face a higher rate of incarceration and lengthier prison sentences in the United States compared to their White counterparts (Alexander, 2012; Steffensmeier et al., 1998; Chiricos & Crawford, 1995). Moreover, racial minorities and young people often face disproportionately harsher penalties for specific offenses such as drug possession (Steffensmeier et al., 1998).
One of the primary drivers of racial inequality in criminal sentencing has been “habitual offender” laws (Crow & Johnson, 2008). These laws impose sentence enhancements for repeat felony offenders and have been enacted by multiple states across the country. While scholars have repeatedly found that Florida’s habitual offender law has been disproportionately applied to racial minorities, virtually no attention has been devoted to Indiana’s habitual offender law (Crawford & Johnson, 2008; Caravelis et al., 2011; Beres & Griffith, 1998).
In order to fill this gap in the literature, I used the Indiana Prosecutor Case Management System to examine case summaries of all habitual offender cases from 2015 to 2019 in Marion, Indiana’s largest and most racially diverse county. For each legal case, I coded the defendant’s race and age, the quantity and nature of their past crimes, the length of the defendant’s sentence, and whether or not they were convicted of the habitual offender enhancement. I then examined the statistical associations between these variables to ascertain whether Indiana’s habitual offender law has been disproportionately applied to young defendants, racial minorities, or drug offenders.

Hola, guapo, ¿qué pasa? Formas de tratamiento como problema de sociopragmática intercultural y didáctica de lenguas
Authors: Baran Marek
Published: April 2023

Recognizing that appellative systems are subjected to particular sociocultural codifications, through this study we try to verify whether the didactic presentation of the address forms, and in particular of the address forms of the Spanish-speaking world, is not limited only to a formal schematization, overlooking the interpretative clues about the scope of use and sociopragmatic conventions. Carrying out the analysis of a few manuals of Spanish as a foreign language, we try to find out what functional values acquire the address forms in the proposed contextualizations. In our approach, we take into account both pronominal and nominal address forms. Similarly, we propose to investigate the question of conceptualizations through which different methods of Spanish as a foreign language reflect the notional contents linked to the contexts of formality and proximity.
Electrochemical analysis of the dissolution of gold in a copper–ethylenediamine–thiosulfate system
Authors: Xiang Peng-Zhi , Liu Qiong , Deng Chao , Ye Guo-hua
Published: April 2023

Thiosulfate gold leaching is a green gold extraction technology. Here, the effects of thiosulfate, copper ion, ethylenediamine, and polarization voltage on the dissolution of gold in this system were investigated by an electrochemical method. The results showed that the addition of thiosulfate promoted the dissolution of gold, but increasing the thiosulfate concentration had a little additional effect. The addition of ethylenediamine also increased the dissolution of gold, but the dissolution resistance of gold increased after adding ethylenediamine. The dissolution of gold increased, the diffusion resistance increased, and the dispersion effect increased upon increasing the copper ion concentration. The copper–ethylenediamine–thiosulfate system did not display passivation (or only weak passivation) upon increasing the polarization voltage, which indicates that the system was relatively stable. The influence of three factors on the dissolution of gold followed the order thiosulfate > copper ion > ethylenediamine.
Research on the behaviour and mechanism of void welding based on multiple scales
Authors: Shi Ruxing , Yu Xingsheng , Chen Huiqin , Jiao Yongxing , Chen Juan , Chen Fei , He Sizhe
Published: April 2023

As the core foundation of major national equipment, large forgings have a great influence on the national economic construction, the development of national defence equipment and the development of modern cutting-edge science and technology. In the production of large forgings, welding the internal void of forgings is a technical problem that directly affects the quality of large forgings. In view of the phenomenon of void welding in large forgings, the behaviour and mechanism of void welding were deeply studied based on the stretching test and molecular dynamics simulation, combined with a lot of theoretical analysis. The results show that multi-pass stretching deformation is a kind of plastic deformation process which can eliminate void defects. When the forging ratio reaches 2.2, the void can be welded completely and the tensile strength can be restored to the level of the matrix. With the increase of compression deformation, the stress will increase sharply, especially at the grain boundary. In addition, the main void welding mechanism of 30Cr2Ni4MoV steel is the recrystallization and grain growth mechanism. Recrystallization and grain growth are of great significance for promoting the reduction of void volume and realizing metallurgical bonding of the interface.

Authors: Clayton Priscilla , Trak-Fellermeier María Angélica , Macchi Alison , Galván Rodolfo , Bursac Zoran , Huffman-Ercanli Fatma , Liuzzi Juan , Palacios Cristina
Published: April 2023

Objectives

Children 10–20 years old in the US are currently obese, showing suboptimal hydration as 60% fail to meet the US Dietary Reference Intakes for water. Studies have shown a significant inverse association between hydration status and body composition in children, although most failed to use the Dual-X-Ray Absorptiometry Scan (DEXA), the gold standard for body composition. Limited studies used an objective marker to measure hydration, such as urine specific gravity (USG) from a 24-h urine collection. Therefore, this study aimed to examine the association between hydration status (measured from USG in a 24-h urine sample and assessed from three 24-h dietary recalls) and body fat % and lean mass (assessed from a DEXA scan) in children (10–13 years, n=34) and adolescents (18–20 years, n=34).

Methods

Body composition was measured using DEXA, total water intake (mL/d) was assessed from three 24-h dietary recalls and analyzed using the Nutrition Data System for Research (NDSR). Hydration status was objectively measured using USG via 24-h urine collection.

Results

Overall body fat % was 31.7 ± 7.31, total water intake was 1746 ± 762.0 mL/d, and USG score was 1.020 ± 0.011 uG. Linear regressions showed significance between total water intake and lean mass (B=12.2, p<0.05). Logistic regressions showed no significant association between body composition and USG and total water intake.

Conclusions

Findings showed total water intake was significantly associated with lean mass. Future research should be conducted to explore other objective markers of hydration and with a larger sample.
Binet's second formula, Hermite's generalization, and two related identities
Authors: Boyack Rufus
Published: April 2023

Legendre was the first to evaluate two well-known integrals involving sines and exponentials. One of these integrals can be used to prove Binet’s second formula for the logarithm of the gamma function. Here, we show that the other integral leads to a specific case of Hermite’s generalization of Binet’s formula. From the analogs of Legendre’s integrals, with sines replaced by cosines, we obtain two integration identities involving logarithms and trigonometric functions. Using these identities, we then subsequently derive generalizations of Binet’s and Hermite’s formulas involving the integral of a complex logarithm.
Racism and Related Concepts in the Russian Linguistic Consciousness
Authors: Denisova-Schmidt Elena , Markovina Irina
Published: April 2023

This paper discusses one approach to investigating the concept of racism and related concepts in the linguistic image of the world of Russian language users. It focuses on the collection of data (associative experiments) and its psycholinguistic interpretation as well as on the theories behind the experiments, including the theory of linguistic consciousness (teorija jazykovogo soznanija). The study outcomes suggest that Russian language users condemn racism but express this condemnation in a culturally specific way, which might lead to significant misunderstandings and conflicts in the international context.
Zur Syntax der polnischen Leichten Sprache
Authors: Radünzel Claudia
Published: April 2023

Easy Language as a means for communicative accessibility is designed for use by people with communication impairments and low literacy skills in general, e. g. persons with intellectual disability, functional illiterates or individuals with dementia. Compared to standard written Polish, the complexity of this variety is reduced on all linguistic levels. The present article deals with the level of syntax and follows on from a previous study concerning the syntax of Easy-to-read Russian. It aims to contribute to the linguistically substantiated elaboration of Easy-to-read Polish by submitting suggestions for avoiding complex syntactic structures. Various subgroups of clause constructions and complex sentences are included. It turns out that the endeavour to make sentences as short, simple and comprehensible as possible is quite complex and certainly not easy. The presented suggestions await further discussion among linguists as well as systematic testing with target groups of Easy-to-read Polish. Since Easy Language has been implemented in Polish legislation, it is to be expected that this fact will result in an amplification of Easy-to-read text offers in the future. Therefore, there is a need for more intensive research in the field of Easy Language that can be seen as crucial in enabling people with disabilities and other persons with reading difficulties to fully enjoy the fundamental right to information and participation in social life.

Authors: Rhaouti Maroua , Lamouime F , Lakranbi M , Smahi M
Published: April 2023

Introduction: Malignant peripheral nerve sheath tumors represent all the neoplasias developed at the expense of cells located in the peripheral nerve sheaths. Complete surgical excision with microscopically healthy edges remains the only curative treatment. Through a clinical case, and a review of the literature, we will report our experience in the management of a tumor of the peripheral nerve sheaths. Observation: Madam K.L, 34 years old, admitted for management of a spontaneously painful left axillary mass, and in whom the clinical examination found a patient, in good general condition, with the presence of a 8cm left axillary mass hard to fixed palpation in relation to the 2 planes, painless on palpation. Thoracic computed tomography revealed an encapsulated left axillary tissue mass compressing the axillary pedicle measuring 84mm*67mm with areas of necrosis. MRI had objectified the presence of a fusiform mass extended to the inter-scalene space most likely evoking a tumor of the malignant peripheral nerve sheaths. The patient had undergone complete tumor excision with section of the left subclavian artery and end-to-end anastomosis, with simple postoperative consequences. Conclusion: MPNSTs are rare tumors. Surgery occupies an essential place in the treatment of this disease, it must be planned in order to avoid vascular and nervous risks. Radiotherapy may be indicated as an adjuvant or in the event of an unhealthy margin.
Neolito bendruomenės ir jų keramika Pietryčių Lietuvoje

Published: April 2023

Molinių indų atsiradimas Pietryčių Lietuvos bendruomenėse VI tūkstantmečio pr. Kr. pabaigoje atspindi ilgai trukusių daugialypių socialinių-ekonominių transformacijų pradžią, sietiną su neolitizacija. Dėl prastų archeologinės medžiagos išlikimo sąlygų ir aptinkamų tik gyvenamųjų vietų, kuriose persimaišę įvairių laikotarpių radiniai, bendruomenių pažinimui svarbiausi šaltiniai – gyvenviečių gamtinė aplinka ir jose randama keramika. Pagal neolitinę keramiką dažnai apibrėžiamos archeologinės kultūros, klasifikuojamos bendruomenės, tačiau ji visų pirma atspindi atskirų individų – puodų lipdytojų meninę išraišką prisitaikant prie kultūrinių tradicijų, tačiau įnešant savitų elementų, taip pat indų gamintojų ir naudotojų socialinį statusą, mitybą, gyvenimo būdą, ryšį su kitomis bendruomenėmis. Detaliai tiriant keramiką ji suteikia informaciją apie gyvenamąją aplinką, florą, fauną, lipdžiusio žmogaus pirštų prisilietimus, jo meninį suvokimą ir technologinius sprendimus. Daugelį archeologinėje literatūroje sutinkamų mitų apie keramiką lemia menkas jos mikrostruktūros ir gamybos procesų suvokimas, todėl disertacijoje pateikiama detali informacija nuo molio masės mineralų, galimų organinių medžiagų ir jų savybių iki indų lipdymo, išdegimo ir panaudojimo. Pietryčių Lietuvos neolitinės keramikos technologiniai sprendimai ir jos panaudojimas atspindi skirtingus bendruomenių požiūrius į aplinkos resursus, dinamiškus tradicijų vystymosi ir perdavimo procesus, prisitaikant prie besikeičiančios gamtinės, kultūrinės ir socialinės aplinkos.

Published: April 2023

Objective: The aim of this research is to investigate the sero-prevalence of hepatitis B (HBV) and hepatitis C (HCV) infection among apparently healthy volunteer blood donors, as well as the relationship between serological evidence of viral hepatitis and age and demographic characteristics. Methods: A retrospective study of sequential blood donation findings from January to December 2017 was performed in North Darfur, Western Sudan. The descriptive quantities were calculated using Chi-square test. Results: A total of 4527 respondents showed an interest in donating blood. All of them were between the ages of 17 and 49 years. A total of 247 (5.5%) and 19 (0.4%) donors tested positive for HBV and HCV, respectively, while 4280 (94.5%) and 4508 (99.6%) donors tested negative for HBV and HCV, respectively. On both HBV and HCV, there was a strong association between serological evidence of viral hepatitis and age (P =0.000). In comparison to the other age categories, the prevalence of HBV and HCV was higher in age group (35-39) and (40 or more) years, (76/247) 30.8 % and (171/247) 69.2 % for HBV and (7/19) 36.8% and (12/19) 62.2 % for HCV. Conclusions: Blood donors in North Darfur have been shown to have a high prevalence of HBV infection and a low frequency of HCV. There was a statistically significant relationship between viral hepatitis and age, but a negative statistically significant relationship between occupancy and age.

Background: This Phase IV post-marketing study was conducted to demonstrate the safety and efficacy of sofosbuvir/velpatasvir fixed-dose combination (FDC) in adult Indian patients with HCV infection as per the recommendation of the Drugs Controller General (India). Methods: This single-arm, open-label, multicenter study was conducted across 22 sites in 409 patients in India. All the eligible patients received once-daily sofosbuvir/velpatasvir (400mg/100mg) FDC for 12weeks. Safety was assessed by monitoring the adverse events (AEs) and efficacy was measured by the proportion of patients achieving sustained virological response (HCV RNA <15 IU/mL or undetectable) at 12weeks after the end of the treatment (SVR12). Results: Between October 2018 to June 2020, 409 patients were enrolled. Twenty patients discontinued the study due to consent withdrawal or lost to follow-up. The SVR12 rate was 90.8%. Sensitivity analysis showed consistent results with SVR12 rates of more than 93%. The combination was well tolerated and none of the AEs reported were related to the study drug, requiring dose reduction, or discontinuation of the study treatment. Conclusions: Once daily sofosbuvir/velpatasvir FDC for 12 weeks was found to be safe, well tolerated, and effective in patients with HCV infection. Trial Registration: The trial is registered at clinical trial registry of India with registration number CTRI/2018/08/015359. (CTRI Trial Data)
Impact of COVID-19 on the Sense of Job Security Among Community Pediatric Hospitalists
Authors: Kim Tae Yeon , Jackson Kelsey , Marek Rachel , Kumar Shelley , Fromme H. Barrett
Published: April 2023

OBJECTIVES

The coronavirus disease 2019 (COVID-19) pandemic offers a prime opportunity to examine the ability of community pediatric hospital medicine programs to respond to external stressors. This study aims to characterize the impact of the COVID-19 pandemic on compensation and furlough among community pediatric hospitalists, as well as self-reported sense of job security.

METHODS

This study was part of a larger quantitative project investigating community pediatric hospitalists’ career motivators. The survey was drafted through an iterative process by the authors. It was disseminated via e-mail to a convenience sample of community pediatric hospitalists obtained through direct contact with community pediatric hospital medicine programs. Data were collected on changes in compensation and furlough because of COVID-19, as well as worry about job security measured as self-reported worry about one’s job being permanently terminated on a 5-point Likert scale.

RESULTS

Data were collected from 31 hospitals across the United States with 126 completed surveys. Because of COVID-19, many community pediatric hospitalists experienced reduced base pay and benefits and a minority experienced furlough. Nearly two-thirds (64%) reported some worry about job security. Initial base pay reduction, working in suburban areas compared with rural areas, and affiliation with a university-based center or free-standing children’s hospital were significantly associated with greater worry about job security.

CONCLUSIONS

The initial response to the COVID-19 pandemic resulted in changes in compensation and furlough for some community pediatric hospitalists and many expressed concerns about job security. Future studies should identify protective factors for community pediatric hospitalists’ job security.

Ecoliteracy lessons have been given to students, but in reality there has been no improvement in awareness of the environment. For example, students still throw garbage carelessly. Ecoliteracy is a means of making students aware of the importance of maintaining environmental balance. The research aims to find the right method or model in teaching ecoliteracy skills in elementary schools (SD). This type of research is literature study. The research subject is a form of elementary school students' awareness of the importance of protecting the environment. While the research data collection method uses the PRISMA method. Meanwhile, the research data collection instrument used a systematic literature review (SLR) which consisted of identifying, evaluating and interpreting the results of previous studies. Sources of research data from Scopus and Eric articles. The data were analyzed using the quality assessment method, namely analyzing article data that is in accordance with ecoliteracy learning in elementary schools. The results of the study found that there were 8 articles, namely: 1) one article problem solving model, 2) two article teaching materials, 3) two article contextual learning, 4) one project-based model, 5) one article adiwiyata school, 6) one article technology. Based on the research findings, it can be concluded that ecoliteracy research specifically discusses ecoliterate learning models in elementary schools, only three articles. In the process of learning ecoliteracy in elementary school, it is necessary to develop a special model for learning ecoliteracy in elementary school.Keywords: Ecoliteration, Elementary Schools
“Beauty of the Person” According to Karol Wojtyła (Ontology and Experience)
Authors: Radziechowski Dariusz
Published: April 2023

This paper outlines the essential core of Karol Wojtyła’s thought on beauty. By introducing the central category of “beauty of the person”, Wojtyła essentially integrated and ordered therewith all the other meanings of the term. Whatever is beautiful in an adequate sense is also morally good. As far as human beauty is concerned, Wojtyła pointed out that it is differentiated by gender, i.e. female beauty and male beauty, and by “layers,” i.e. external beauty (aesthetic, sensual and bodily beauty) and, more importantly, internal beauty, which constitutes the beauty of a person as a person. Outer beauty allows a person to be noticed, to be discovered, but in love one cannot stop at outer beauty (the temptation to treat the body as a possible object of use). For love is love of the whole person, not only of his or her beautiful body and sexual attractiveness. A specific issue is the analysis of the creation of beautiful things, which at the same time are imprinted in the interior of man and – as long as man does not give in to the egoistic “temptation of self-emptying” – bear witness to his “immortality.”
A Novel Generative Image Inpainting Model with Dense Gated Convolutional Network

Damaged image inpainting is one of the hottest research fields in computer image processing. The development of deep learning, especially Convolutional Neural Network (CNN), has significantly enhanced the effect of image inpainting. However, the direct connection between convolution layers may increase the risk of gradient disappearance or overfitting during training process. In addition, pixel artifacts or visual inconsistencies may occur if the damaged area is inpainted directly. To solve the above problems, we propose a novel Dense Gated Convolutional Network (DGCN) for generative image inpainting by modifying the gated convolutional network structure in this paper. Firstly, Holistically-nested edge detector (HED) is utilized to predict the edge information of the missing areas to assist the subsequent inpainting task to reduce the generation of artifacts. Then, dense connections are added to the generative network to reduce the network parameters while reducing the risk of instability in the training process. Finally, the experimental results on CelebA and Places2 datasets show that the proposed model achieves better inpainting results in terms of PSNR, SSIM and visual effects compared with other classical image inpainting models. DGCN has the common advantages of gated convolution and dense connection, which can reduce network parameters and improve the inpainting effect of the network.

In this pandemic situation, radiological Images are the biggest source of information in healthcare and, at the same time, one of the foremost troublesome sources to analyze. Clinicians now-a-days must depend to a great extent on therapeutic image investigation performed by exhausted
radiologists and some of the time analyze and filter themselves. Due to overflowof patients, transmission of these medical data becomes frequent and maintaining confidentiality turns out to be one of the most important aspects of security along with Integrity and availability. Due to varied
features of image data, different algorithms are used to protect data from unauthorized access. This paper basically center on the distinctive cryptographic techniques used for the image encryption and decryption of the medical image data within the field of information security. In addition,
a comparative analysis is carried out among the parameters used to measure security of the existing literatures.
Visual search patterns for multilingual word search puzzles, a pilot study
Authors: Beelders Tanya
Published: April 2023

Word search puzzles are recognized as a valid word recognition task. Eye gaze patterns have been investigated during visual search and reading, but the word search puzzle requires both searching and word recognition. This paper will discuss findings from an eye-tracking study of word search puzzles in three languages, of varying fluency for the participants. Results indicated that participants employ a search strategy that is somewhat dependent on language fluency and varies from a rigid, structured search pattern to randomly searching for a target word. The majority of gaze measurements are not significantly influenced by either word length or fluency of presented language, although mean fixation durations are longer for shorter words.

This study aims to support a mandatory reading of a novella for high school students by a serious game. The study includes 41 students. The first class is included in the experimental study, which uses a serious game to read the novella. The second class served as the control group and engaged only in analog reading. The evaluation is based on a questionnaire with reading, user, and narrative engagement items. Furthermore, the assessment consists of in-depth interviews with teachers and students. The findings positively affected students’ engagement in the experimental group. Primarily focused attention and reward are higher in the experimental group. However, there was no difference in the narrative engagement between the two groups, indicating that the story (digital or not) is well explained. The qualitative findings revealed positive comments, especially for the reading engagement and the story world. The novelty in this study is the outlined game design process, guided by elements in the foundation, game design, prototyping, and implementation. For the game design, we outlined how to transform the principles from Sweetser and Wyeth to applied design implementations. An important aspect was to illustrate the protagonist with schizophrenia.
Perfecting a General Notarial Bond: You Can't Have your Cake and Eat It! ABSA Bank Limited v Go on Supermarket (Pty) Limited (The Spar Group Limited intervening) (9442/2022) [2022] ZAGPJHC 173 (24 March 2022)
Authors: Koekemoer Michel Marlize , Brits Reghard
Published: April 2023

A general notarial bond registered over movable property grants the bondholder a real security right enforceable against third parties only if the bond has been perfected by transferring possession of the property to the bondholder. Based on the facts and judgment in Absa Bank Limited v Go On Supermarket (Pty) Limited, this analysis revisits the basic principles of and requirements for the perfection of a general bond. We ultimately criticise the judgment on three scores. Firstly, the court regarded the form of delivery (transfer of possession) applicable in this matter as symbolic delivery, but we point out that it amounted to constitutum possessorium – meaning that the attempted perfection of the bond was ineffective. Secondly, the parties conceded and the court accepted that the general bond could not be perfected over property subject to the special notarial bond of another creditor. We reason that this is incorrect. It is indeed possible to attach property subject to the security right of another creditor, although the first creditor's rights will be preferred over those of the creditor who subsequently attached the property. Thirdly, the court rejected the argument that the general bond could not be perfected over property owned by another creditor in terms of a reservation-of-ownership clause in a sale agreement. However, the court should not have rejected this argument, since it was correct. A general bond indeed cannot cover property belonging to someone other than the debtor, unless the person agreed, and thus it was not possible in this case to attach the property belonging to someone other than the debtor.

Introdução: A obesidade infantil está em crescente aumento em nosso país, estando fortemente relacionada a mudanças socioeconômicas e a transição nutricional, caracterizando hábitos alimentares inadequados e alterações no estilo de vida, sendo fatores de risco precoce para surgimento de comorbidades. Objetivo: Revisar na literatura os hábitos de consumo alimentar e estado nutricional de escolares. Metodos: Revisão integrativa de estudos científicos das bases de dados Scientific Electronic Library Online (SciELO), Google Acadêmico, PubMed (NCBI) e LILACS, do período de 2015 a 2020, nos idiomas português, inglês e espanhol, preferencialmente escolhendo artigos originais. Para a busca foram usados os descritores: “estado nutricional e consumo alimentar de escolares”, “hábitos alimentares de escolares”, “estado nutricional de escolares”, “preferências alimentares”, “mudanças alimentares”, “alterações de peso corporal”, “comportamento alimentar”, “obesity”, “food consumption”, “nutritional status” e “alimentación escolar”. Resultados: Foram encontrados 134 artigos em análise inicial de títulos, em segunda análise foram selecionados 27 por meio da leitura dos resumos e após leitura completa foram excluídos os que não atenderam ao objetivo do estudo, sendo selecionados 8 artigos para condução do trabalho. Uma alimentação variada, baseada em alimentos in natura está relacionada com escolares eutróficos, em contrapartida, escolares que realizam poucas refeições ao dia e apresentam dietas ricas em alimentos industrializados possuem alterações de peso, como sobrepeso e obesidade. Nesse contexto, ocorre o acréscimo da prevalência de sobrepeso e obesidade em escolares e declínio dos índices de desnutrição. Constatou-se a influência da escola e da família nas práticas alimentares, sendo as atividades de Educação Nutricional boas estratégias para melhora dos hábitos alimentares de escolares. Conclusão: A alimentação rica em alimentos industrializados apresentou correlação positiva com alterações no estado nutricional, principalmente excesso de peso em escolares, interferindo no desenvolvimento, crescimento, em alterações metabólicas, podendo ser preditores para doenças crônicas não transmissívei e consequentemente interferir na qualidade de vida.
