Identification of Children Using HOG
Authors: Abraham Jobin Reji
Published: December 2022

Abstract: Adults often utilize biometric recognition for a variety of tasks that require a personal identification evidence to be validated. Children's biometric identification, however, is still a challenge. In addition to helping find lost children and their families, developing border control systems to stop child trafficking, and assisting electronic recordkeeping systems, addressing this issue helps safeguard children against identity theft and identity fraud. Researchers are gathering biometric data from newborns' fingerprints, irises, and outer ears in order to start creating biometric recognition systems for kids. Children's ear mode was implemented using the hardware and software that were previously utilized for adults. Existing hardware was utilized in iris mode to find iris pictures. In order to capture children's fingerprints and transform the pictures into a backdrop format that complies with current international standards for issuing and comparing minutiae, new image processing gear and software have been created. Based on analyzing the effectiveness of usage and measuring the amount of performance, the benefits and drawbacks of utilizing each of these strategies throughout the first year of life were compared. Recommendations for the usage of each approach were given, despite the fact that they weren't always best practices.

Therefore, related studies were collected, and the subjects of the studies were analyzed through the frequency of the topics and the correlation of research subjects.
Methods Utilizing keyword ‘Self-directed’, ‘learning’, and ‘education’ with ‘detailed keyword search’, 160 KCI and KCI candidate journals published for last 10years are selected from RISS. A total of 640 keywords(4 from each article) from the selected 160 articles are analyzed utilizing Network Text Analysis.
Results The main results derived accordingly are as follows. First, research on ‘Self-directed learning’ has continued albeit in small numbers. Second, the most appearing keyword was ‘College education’ both in frequency and centrality analysis. Third, the research has been applied and studied in various subjects. Forth, the cluster of subjects consists of five groups, and the connection between “college education” and “satisfaction” was relatively high.
Conclusions Considering that the case of the SOLE of Sugata Mitra, an application of self-directed learning in the international community, conducting various studies in the expanded scope is meaningful. Since many studies have been mainly applied to university education setting in Korea, expanding the scope of studies to elementary education, secondary education, and lifelong education is able to deduce meaningful results. Second, it seems that self-directed learning can be applied in various integrated themes. Third, the contents and methods for teacher training in international education development cooperation need to be changed based on the philosophy of self-directed learning. Forth, it is suggested to devise a self-directed learning environment using mobile phones, considering the lack of “Broadband” and the dramatic growth in the supply and use of mobile phones in East African countries.

Quantum Fully Homomorphic Encryption by Integrating Pauli One-time Pad with Quaternions
Authors: Ma Guangsheng , Li Hongbo
Published: December 2022

Quantum fully homomorphic encryption (QFHE) allows to evaluate quantum circuits on encrypted data. We present a novel QFHE scheme, which extends Pauli one-time pad encryption by relying on the quaternion representation of SU(2). With the scheme, evaluating 1-qubit gates is more efficient, and evaluating general quantum circuits is polynomially improved in asymptotic complexity.
Technically, a new encrypted multi-bit control technique is proposed, which allows to perform any 1-qubit gate whose parameters are given in the encrypted form. With this technique, we establish a conversion between the new encryption and previous Pauli one-time pad encryption, bridging our QFHE scheme with previous ones. Also, this technique is useful for private quantum circuit evaluation.
The security of the scheme relies on the hardness of the underlying quantum capable FHE scheme, and the latter sets its security on the learning with errors problem and the circular security assumption.

Authors: Singh Punit , Kori Mohan Lal
Published: December 2022

Ulcer is defined as a rupture in the skin or mucus membrane with loss of surface tissue. It has defects in the epithelium, caused by a lesion with a lost epithelial layer in the stomach or diffused loss of mucosal layer within the oral cavity. The present study aimed to investigate the preliminary screening of Momordica charantia Linn. leaves for oral and stomach ulcers. The leaves of Momordica charantia Linn. were extracted with different solvents with increasing polarity. Preliminary phytochemical tests were carried out to detect the presence of various chemical constituents in petroleum ether, chloroform, ethyl acetate, ethanol, and aqueous extracts. Initial screening was done for the antiulcer effect on ethanol-induced stomach ulcers and glacial acetic acid oral ulcers. The antiulcer effect was observed by they measured the ulcer index, percentage inhibition of ulcer, gastric pH, total acidity, and gastric volume. In addition, biochemical assessments of proinflammatory mediators (TNF-α, IL-6, and PGE-2) were performed in mucosal tissues. Results of phytochemical screening revealed the presence of steroids, terpenoids, alkaloids, flavonoids, tannins, glycosides, and phenolic compounds. Results of in vivo study showed that the antiulcer effect was observed in a dose-dependent manner. Ethanolic extract of Momordica charantia Linn. with 200 and 400mg/kg b.w. Doses have significant antiulcer potential and were comparable to the standard (Omeprazole and ORASORE Gel). A significant (p<0.05) reduction in ulcer index and percent inhibition was observed in the stomach and oral cavity ulcers. Furthermore, the practical (p<0.05) restoration of inflammatory mediators indicated a supporting mechanism of ulcer healing of ethanolic extract. In conclusion, the antiulcer effect was shown in a dose-dependent manner may be due to the presence of secondary metabolites like phenolic compounds viz., flavonoids, and tannins in the ethanolic extract of Momordica charantia Linn.

Published: December 2022

Em janeiro de 2020 um novo tipo de coronavírus foi identificado: o SARS-CoV-2. Devido à alta transmissibilidade do vírus e à gravidade com que a COVID-19, doença por ele causada, se manifesta, mostrou-se necessário o isolamento social, o que afetou severamente os sistemas educacionais. Esses encontraram nas tecnologias de informação e comunicação – TIC uma solução possível para a emergência, o processo denominado como “ensino remoto”. Conhecer como professores de Química têm experenciado a docência durante esse período é o objetivo da pesquisa descrita. Trata-se de um estudo de caso em que um questionário de respostas abertas foi aplicado a professores de municípios localizados ao norte da Região Metropolitana do Rio de Janeiro. O pensamento de Edgar Morin foi o fundamento para a construção dessa investigação (MORIN; CIURANA; MOTTA, 2009; MORIN, 2020), o que levou a uma abordagem sensível, aberta e complexa do próprio processo investigativo. Enquanto teorias educacionais organizadoras do estudo foram empregadas teorias pedagógicas, de acordo com Libâneo (2006) e Freire (1987). Para a interpretação das respostas usou-se a Análise Textual Discursiva (MORAES; GALIAZZI, 2006). Os resultados revelam desafios pedagógicos e pessoais enfrentados pelos professores no período de adaptação à emergência educacional, como também a forma como esses desafios foram superados, quais as impossibilidades identificadas e quais as reflexões que decorreram dessa experiência. Como conclusões tem-se que, diante dos problemas enfrentados, os professores encontraram soluções didáticas para sua ação profissional, mostrando-se inovadores, assim como evidenciaram seu lado humano e sensível frente às dificuldades dos alunos e colegas, reconhecendo a necessidade de aproximações e partilhas.PALAVRAS-CHAVE: Docência; Ensino de Química; Educação Básica; COVID-19.

Published: December 2022

O presente artigo possui como objetivo central promover a discussão dos impactos dos processos de educação remota implementados durante a pandemia da COVID-19 nas escolas de Educação de Jovens e Adultos da rede estadual de educação do Rio de Janeiro. Assume destaque no trabalho os processos de resistência e de assimilação pelos docentes das diretrizes praticadas pelo poder público, onde foi conferida à educação remota um lugar central. Em contraposição às muitas contradições presentes no Ensino Remoto, devemos considerar que o processo de didatização dos conteúdos em práticas escolares é muito intricado e se estrutura por variados e distintos procedimentos complementares que se conjugam, chocam-se, estabilizam-se e se transformam temporalmente, por outro lado, conciliam os diferentes saberes que os professores mobilizam, como o saber de sua disciplina de referência, o saber pedagógico e, principalmente o saber da experiência. No entanto, de forma aligeirada e abrupta, sem formação específica ou experiência prévia, a comunidade escolar foi inserida em um experimento social sem precedente na história recente da educação escolar no Rio de Janeiro, com o estabelecimento de uma educação remota de grande envergadura, mas com pouco alcance efetivo sobre a comunidade escolar e, em perspectiva, com parcos resultados promissores para os processos de ensino e aprendizagem, principalmente considerando as especificidades dos educandos jovens e adultos.PALAVRAS-CHAVE: Educação de Jovens e Adultos; Ensino Remoto; Prática Docente; Absenteísmo Digital

Authors: ÖNSAL Gülnur
Published: December 2022

The dielectric anisotropy (Δε') is the response of the LC molecules to an applied electric field. In this study, the dielectric properties of 4-pentyl-4'-cyanobiphenyl (5CB) and N-(4-methoxybenzylidene)-4-butylaniline (MBBA) nematic liquid crystals with positive and negative dielectric anisotropy were investigated in detail. In addition, a structure with zero dielectric anisotropy was obtained by mixing MBBA and 5CB liquid crystals in certain rate (1:0.02). The behavior of the samples under 0V and 20V voltages was investigated in detail. Dielectric measurements were made with dielectric spectroscopy technique, which is a powerful method to investigate the molecular interaction mechanisms of liquid crystal materials, at a frequency of 1 kHz-10 MHz and a voltage of 0-20 V at room temperature. Some important parameters such as dielectric anisotropy (Δε'), relaxation frequency (fR), relaxation time (τ) were determined for the samples. When electric field is applied to nematic liquid crystals, it is seen that, depending on the voltage, the relaxation frequency decreases, and the relaxation time increases.
Development of High-Density SNP Markers for Evaluating Genetic Diversity and Population Structure in Pingwu Red Chicken
Authors: Wang Yuwei
Published: December 2022

Broilers supply humans with an abundance of high-quality chicken, and
the utilization of local poultry genetic variety is crucial for the
development of high-performing and efficient broiler breeders. Pingwu
red chicken is an outstanding native poultry genetic resource in Sichuan
Province, yet research on Pingwu red chicken DNA polymorphism lags
behind that of standard broiler breeds. To uncover the genetic variety
of Pingwu red chickens, blood genomic DNA from 18 Pingwu red chickens
was extracted, and high-throughput locus-specific amplified fragment
sequencing (SLAF-seq) was utilized for SNP marker analysis and
phylogenetic tree construction. To investigate the genetic evolutionary
relationship of Pingwu red chickens, a total of 952,944 high-quality
SNPs (integrity > 0.5 and MAF > 0.05) and SLAF
fragments were gathered, according to the study. This study successfully
uncovered the genetic foundation of Pingwu red chicken, indicating the
existence of three tiny clusters across all samples. Specific-length
amplified fragment sequencing (SLAF-seq) is a high-resolution technique
for identifying and genotyping de novo SNPs. This study concludes that
slaf-seq is an effective method for revealing the genetic variety of
Pingwu red chickens and provides a scientific basis for its use in
Pingwu red chicken evolution.

threatening their ecological balance. This trend concerns both the
lowland rivers flowing in densely populated areas, and the alpine
headwaters, where the effects of global change are dramatically evident
and often accompanied by alterations in river hydro-morphology. In
mountainous river stretches, regulation and morphological alterations
such as bank reinforcement, water abstractions, dams, and weirs are
increasing. In the Alps, protected areas and especially large National
Parks constitute an effective strategy to face the loss of biodiversity,
but little is known about their effectiveness regarding lotic
environments. To examine the recent trend in aquatic communities in
Alpine protected areas, we carried out biological samplings and
hydro-morphological evaluation in twelve high-altitude streams within
the oldest Italian National Park, the Gran Paradiso Park, located in the
heart of the Western Alps, and we compared results with a previous
survey performed in 2005, keeping the same experimental design. Our
results detected minimal changes in the hydro-morphology of the studied
watercourses. Biomonitoring indices associated with benthic communities
likewise do not evidence significant differences. Concerning diatom
flora, we found however in 2020 a greater uniformity in species
composition compared to communities of 2005, and a slight turnover
between species. In conclusion, our findings underline the effectiveness
of protected areas for the conservation of running water environments
because they limit hydro-morphological alterations thus increasing the
resilience of aquatic communities to climate change.
Sexual dimorphism as a facilitator of worker caste evolution in ants
Authors: Smith Chris
Published: December 2022

Ant societies are primarily composed of females, whereby labor is
divided into reproductive and non-reproductive, worker, castes. Workers
and reproductive queens can differ greatly in behavior, longevity,
physiology, and morphology, but their differences are usually modest
relative to the differences relative to males. Males are short-lived,
typically do not provide the colony with labor, often look like a
different species, and only occur seasonally. It is these differences
that have historically led to their neglect in social insect research,
but also why they may facilitate novel phenotypic variation – by
increasing the phenotypic variability that is available for selection.
In this study, worker variation along a size-shape axis corresponded
with variation in male-queen size and shape. As worker variation
increased within species, so did sexual variation. Across species in two
independent genera, sexual size dimorphism correlated with worker
polymorphism regardless of whether the ancestral condition was large or
small worker/sexual dimorphism. These results, along with mounting
molecular data showing that process of queen-worker caste determination
has co-opted many genes/pathways from sex determination, lead to the
hypothesis that sexual selection and selection on colony-level traits
are non-independent and that sexual dimorphism may even have facilitated
the evolution of the distinct worker caste.

Application of Full Automation as an Additional Tool for Effective Payment of Salaries of Civil Servants of Federal Government of Nigeria
Authors:   Department of Computer Science, National Open University of Nigeria  Abuja, FCT, Nigeria, Greg Onwodi
Published: December 2022

Automated systems can easily achieve significantly superior performance in terms of power, precision and speed of operation. It involves the conversion of a work process, a procedure, or equipment to automatic rather than human operation or control which premised on a deep re-organization of the work process, during which both the human and the machine functions are redefined. Early automation relied on mechanical and electromechanical control devices; however, the computer gradually became the leading vehicle of automation which is usually associated with computerization, digitization and digitalization. Automation has found itself to be a very important tool in the all sectors of life. This thesis is therefore focused majorly on the application of system automation as an additional tool for the payment purposes. It also provides a web based solution for account details verification to ensure 100% payment. Keywords: Automation, Payment, Salaries, Civil Servants, Web-based Solutions, Nigeria
Smart Intrusion Prevention System for the Local Area Network of Nigeria Immigration Special Study Centre, Gwagwalada, FCT, Abuja, Nigeria
Authors:   Department of Computer Science, National Open University of Nigeria  Abuja, FCT, Nigeria, Onwodi Greg
Published: December 2022

This study examines the Smart Intrusion Prevention System for the Local Area Network of Nigeria Immigration Special Study Centre, Gwagwalada, Abuja. Different research methodologies for Intrusion Prevention System was analysed and the hybrid based methodology was adopted because of its incorporation of the other methodologies. Configuration of the Intrusion Prevention System was studied and implemented using software known as Mikrotik. The Mikrotik software configuration was analysed properly. Among the major findings of the study was that the Local Area Network of Nigeria Immigration Special Study Centre, Gwagwalada, Abuja was relatively insecure with the sophisticated breed of attackers we have now. The study therefore recommended that Nigeria Immigration Special Study Centre, Gwagwalada, Abuja should integrate a known Intrusion Prevention System software and endeavour to keep it updated at all times. Also, they can work on system design and algorithm design for secure communication over complex networks.

Impaired Awareness of Hypoglycemia in Type 1 Diabetes: A Report of An NIDDK Workshop in October 2021
Authors: Seaquist Elizabeth R. , Teff Karen , Heller Simon R.
Published: December 2022

Hypoglycemia remains a limiting factor in the optimal treatment of type 1 diabetes. Repeated episodes of hypoglycemia result in impaired awareness of subsequent hypoglycemic events, inducing a vicious feed-forward cycle and increasing the risk of morbidity and mortality. Why this occurs and how to manage the problem in clinical practice remain uncertain. To address the obstacles and barriers that have hindered progress in this clinically important area, the National Institute of Diabetes and Digestive and Kidney Diseases convened a workshop on 14–15 October 2021. This perspective offers a summary of this outstanding meeting, which brought clinical and basic scientists from the fields of diabetes, neuroscience, psychology, psychiatry, and imaging together, on how to best advance the field of impaired awareness of hypoglycemia and hypoglycemia in general in patients with diabetes.
Democracy as experimentalism and experimentalism as anti-dogmatism
Authors: Saharrea Juan , Campeotto Fabio , Viale Claudio Marcelo
Published: December 2022

The purpose of this paper is twofold: to reconstruct Dewey’s conception of experimentalism, mainly through his pedagogical writings, on the one hand; and to show the relevance of this reconstruction to current reassessments of Dewey’s political thought, on the other. The grounds for our perspective have a double character too. Firstly, we reconstruct the links between experimentalism and education on the basis of the first edition of How We Think (1910, MW 6), perhaps one of Dewey’s most noteworthy pedagogical texts. Secondly, we critically address three different reassessments of Dewey’s experimentalism in contemporary political thought, namely: 1) Pappas’s defense of Dewey’s substantive idea of democracy; 2) Forstenzer’s proposal of Deweyan experimentalism as an appropriate methodology for political philosophy; and 3) Anderson’s vindication of Deweyan experimental democracy in the context of social epistemology. It is sustained that in HWT Dewey places experimentalism as a kind of antidote against dogmatism and unreflective ways of reasoning. Thus, he links experimentalism with anti-dogmatism placing a special role in schooling for at least two reasons: 1) it is in the schooling phase that children are still sensitive to the development of certain habits; 2) dogmatism seems inevitable in any society but the educational phase is a key instance to try to avoid it. Neither (1) nor (2) are present in contemporary reassessments of Deweyan experimentalism.
