Published: December 2022

The stigma associated with AIDS is a setback for HIV/AIDS prevention, care, and treatment. Persons living with HIV/AIDS (PLWH), and those that fear they might be HIV-infected, fear judgment and discrimination from within their community, and more especially from their health care services. Thus, this study seeks to establish a baseline index of the stigma level for HIV in Saint Kitts and Nevis (SKN), as well as estimate this level among local health care providers (HCP). A total of 88 participants volunteered for the study, consisting of 43 PLWH and 45 HCP. Data from the PLWH was collected by trained physicians, while the HCP collected their data via a self-administered questionnaire. The results of the study reveal that the majority of PLWH had experienced stigmatization due to their health condition, either externally or internally, or both. The study revealed deficiencies in HIV-patient counseling and possible breaches of confidentiality regarding HIV status disclosure. However, the results of the study statistically showed an occupational bias concerning potential confidentiality breaches, as none of the skilled participants had their status revealed without their permission. This differed for the semi-skilled and unskilled participants. Amongst the HCP, the study revealed both passive and active displays of HIV stigma, attributed mainly to insufficient training. The study also revealed that HCP’s perception of their work environment in terms of safety negatively impacted their interaction with the PLWH. The results of this study underline the need for active participation from the SKN Community and Government, to ensure the quality of life for PLWH, as this could have a boomeranging effect on the health of the society as a whole.

Published: December 2022

Dr. Yap Eye Hospital, Yogyakarta uses aseptic gel containing 70% ethyl alcohol to refill antiseptic containers during times of antiseptic scarcity. The study aimed to evaluate the effectiveness and sterility of the refill antiseptics in reducing the number of colonization on the hands of nurses. It was a quasi-experimental using pre- and post-control groups design involving 56 nurses who used antiseptics in a bottle sterilized by plasma device (plasma bottle) compare to those washed using detergent (detergent bottle) before being refilled. Sterility tests were performed every two wk for up to two mo. Colonization pre and post hand hygiene practices were determined as an efficacy test and compared using the Mann-Whitney test in STATA 14. Antiseptic in plasma bottles remains sterile until the week8th since refilled, longer than detergent bottles (6th weeks). The pre-handrub colorizations were 0.04-16.92 CFU/cm2 and decreased significantly post-handrub to 0.00-3.08 CFU/cm2 (p<0.0001). Significant decrease pre- vs post-handrub colonization was observed in usage of detergent bottle (0.04-31.04 vs 0.00-10.48 CFU/cm2, p=0.0007). There was no significant difference in ∆ colonization for two bottles (0.40-15.76 vs 0.04-30.92 CFU/cm2, p=0.8790). In conclusion, antiseptic in the plasma bottle remains sterile longer than in the detergent bottle since refilled. Both of them are equally effective in reducing colonization after handrub activity.

Development of teachers' meta-competencies using pedagogical facilitation
Authors: Koroleva Anna V.
Published: December 2022

The meta-competencies in professional activity are as important as their development ways in the system of general and vocational education. An integrated approach is necessary in the formation of meta-competencies as universal flexible structures in the basis for professional competencies both in the process of vocational education and in obtaining direct work experience. They begin to form spontaneously mainly during the period of secondary general education, therefore it is advisable to make this process more manageable. Suggested pedagogical facilitation is a suitable tool for this. However, the organization and implementation of the facilitation session requires the teacher to have experience as a participant. We describe the methodology of organizing the practical part of the advanced training course for teachers of specialized classes of Derzhavin Tambov State University based on the principles of pedagogical facilitation. The purpose of the practical part of the course is to create educational technology as an author's collective product. The use of pedagogical facilitation in this case allows teachers to gain positive experience of participation in the facilitated process, creation of a group creative product, new application of their personal pedagogical experience, development of their own meta-competencies. In general, the results recorded in the form of created collective author's educational technologies and feedback from the course participants confirm the effectiveness of our approach to organizing a refresher course for teachers. It is concluded, that teachers have a unique professional experience, the best of which can be transformed into an effective author's educational technology if they are given a new form (structure of educational technology) and combine their efforts in a pedagogical facilitation session.

Hadis Im?mah Jibr?l Perspektif Astronomis
Authors: Awaludin Muhammad , Sofyan Muhammad Saleh , . Sazali
Published: December 2022

Hadis Im?mah Jibr?l merupakan hadis yang paling lengkap dan banyak dipakai sebagai dasar penentuan waktu salat oleh ulama fikih. Di dalamnya, Jibr?l datang kepada Rasul dan menunjukkan waktu salat dalam dua hari yang berbeda. Jika tidak dilihat dari perspektif astronomis, secara redaksional, hadis ini mengandung ambiguitas. Di hari pertama Jibr?l menunjuk untuk mengerjakan waktu salat Zuhur ketika panjang bayangan telah sama dengan bendanya, sementara di hari yang kedua, justeru salat Asar yang dikerjakan di waktu itu.

Makalah ini menganalisis hadis Im?mah Jibr?l itu dari perspektif Astronomi agar tidak menimbulkan kesan ambigu. Pembacaan astronomis terhadap Im?mah Jibr?l dalam makalah ini menunjukkan bahwa hadis ini telah terkonfirmasi oleh teori-teori astronomis. Artinya, hadis ini telah mempertimbangkan pergerakan kemiringan semu matahari (dalam ilmu falak disebut sebagai deklinasi) yang memberi pengaruh kepada perbedaan panjang bayangan ketika Zuhur dan Asar dalam satu tahun. Pembacaan ini membuktikan Jibr?l sebagai pembawa wahyu Tuhan, sejak lebih dari seribu dua ratus tahun yang lalu, telah menerapkan teori yang kemudian dirumuskan dan dikembangkan di abad modern ini. Dengan kata lain, makalah ini juga membuktikan bahwa hadis sebagai salah satu sumber ajaran Islam, akan senantiasa relevan di tempat manapun dan kapanpun juga

A plataforma digital YouTube tem se tornado popular entre as crianças e uma prática cuja popularidade vem aumentando nesse espaço é a do unboxing, que consiste em vídeos nos quais seus protagonistas, denominados YouTubers, abrem embalagens e fazem demonstração de novos produtos, como brinquedos e itens colecionáveis. O presente artigo buscou analisar, à luz do Direito do Consumidor, se a eventual publicidade veiculada por meio desses vídeos gera responsabilidade civil por publicidade ilícita do YouTuber anunciante. Para tanto, foi realizada pesquisa exploratória de natureza bibliográfica, em doutrina especializada, e documental, a partir das decisões do Conselho Nacional de Autorregulamentação Publicitária. Foi empregado o método indutivo, uma vez que se partiu de uma análise de fatos específicos a respeito da atuação dos YouTubers para uma conclusão geral referente ao tema da responsabilidade civil por publicidade ilícita. Verificou-se a presença de elementos da publicidade ilícita nos vídeos unboxing, não só pela abusividade do direcionamento ao público infantil, mas também pelo caráter velado da publicidade. Ademais, concluiu-se pela responsabilidade civil objetiva dos YouTubers que veiculam tais conteúdos, visto que participam ativamente da elaboração da comunicação mercadológica e podem receber contraprestação da empresa fornecedora, além de exercerem grande influência sobre seus seguidores.
Variable vs. Fixed Dosing of Monoclonal Antibodies in Oncology
Authors: Tzenios Nikolaos , Tazanios Mary , Chahine Mohamad
Published: December 2022

Oncological patients need the proper doses of medications to facilitate their recovery. The two basic approaches used in dosing Monoclonal Antibodies (mAbs) are fixed-dose combination and variable dosing. In Fixed-Dose Combination Drugs (FDCs), two or more active components are combined in a single formulation at a predetermined dose. Variable dosage, which has long been the industry standard, is the polar opposite of this approach. The body changes over time; the Body Surface Area (BSA) in square meters is often used as a Measure (m2). This study uses a systematic review. Most mAbs used in oncology are predominantly given as cytotoxic anticancer drugs using body-size-based (variable) regimens. Despite the benefits of fixed-dose, variable dosing has become the industry standard, despite being criticized for ineffectiveness. While variable dosing has some advantages, the prevalent view is that continuous dosing has significant advantages based on the balance of probabilities. After assessing each alternative, including its benefits and drawbacks, history of use, and suitability in the current context, fixed dosing emerges as a viable option.

The compound was tested as a potential inhibitor of human monoamine oxidase (MAO) A and B. It demonstrated notable inhibition with an IC50 value of 0.036 μM for MAO-B and isoform specificity. The product was characterized by 1H NMR, 13C NMR, and HRMS. In conclusion, the new active MAO-B inhibitor may serve as a candidate for the future discovery of therapeutic agents for neurodegenerative disorders such as Parkinson’s disease.
History of Advances in Genetic Engineering of Viruses Prior to COVID-19 Pandemic
Authors: Teppone Mikhail
Published: December 2022

Due to the fact that to date, the question of the origin of SARS-CoV-2 has not been resolved yet, the author analyzed the main advances in the development of genetic engineering of viruses that took place before the onset of the COVID-19 pandemic. The first artificial genetically modified viruses could appear in nature in the mid-1950s. The technique of nucleic acid hybridization was developed by the end-1960s. In the late 1970s, a method called the "reverse genetics" emerged to synthesize RNA and DNA molecules. In the early 1980-s, it became possible to combine the genes of different viruses and insert the genes of one virus into the genome of another virus. Since that time, the production of vector vaccines began. Currently, by modern technologies one can assemble any virus based on the nucleotide sequence available in the virus database or designed by a computer as a virtual model.Scientists around the world are invited to answer the call of Neil Harrison and Jeffrey Sachs of Columbia University, for a thorough and independent investigation into the origin of SARS-CoV-2. Only a full understanding of the origin of the new virus can minimize the likelihood of a similar pandemic in the future.

Published: December 2022

Software-defined networks (SDN) seek to solve the problems in current network schemes by simplifying their management through their reprogrammability and accessibility to the overall network infrastructure. One aspect to improve in SDN-based schemes is the precise classification of your traffic load, this can improve various aspects such as quality of service, dynamic access control, prioritized random access, among others. This research aims to propose a conceptual architecture of SDN and evaluate different machine learning methods for traffic classification. To this end, SDN architectures are analyzed and different modules are proposed to strengthen their management with the help of low computational cost classifiers. The architecture proposes the following main modules: Capture network traces module, Learning Engine module, and ML-model and Flow classifier. To determine the model to be used in the Learning Engine and Flow classifier modules, different classifiers were evaluated using a database of network traffic, as a result, it was determined that the gradient boosting algorithm is the most suitable to be integrated with the proposed SDN architecture.

La presente investigación tiene como objetivo determinar la fuerza de agarre aplicada en los 5 niveles de abertura del dinamómetro hidráulico Jamar en operadores de producción de una industria médica en Ciudad Juárez, Chihuahua, México. La muestra se conformó por 54 participantes mayores de edad. Se obtuvieron medidas con un dinamómetro hidráulico de Jamar solo de la mano dominante. Para determinar diferencias significativas en los niveles de abertura se realizó un análisis ANOVA de un solo factor con el software Minitab 20, el cual dio como resultado un valor p menor que α=0.05, con un nivel de confianza del 95 %. La abertura óptima en el que se obtuvo mayor aplicación de fuerza de agarre tanto en hombres como en mujeres fue en el nivel 2, obteniendo una media de 41.33 kgf para los hombres y 26.74 kgf para las mujeres, mientras que el nivel donde se obtuvo menor aplicación de fuerza fue el 5 para ambos géneros. Se concluyó que el nivel de abertura del dinamómetro influye de forma significativa sobre la aplicación de fuerza, por lo que es importante que estas consideraciones sean tomadas en cuenta al memento de diseñar herramientas manuales de trabajo.
Videoanálisis y técnica Monte Carlo para calcular la cota máxima de la fuerza de una patada
Authors: Torres-Zúñiga Vicente
Published: December 2022

En este estudio, se analizó la videograbación casual de un testigo, donde un luchador profesional patea a un adversario y, complementando con información pública, se estimó la fuerza de las piernas al dar el golpe. Sin embargo, siendo los datos obtenidos de una fuente secundaria, las ecuaciones deterministas por sí solas son inadecuadas para calcular la incertidumbre asociada, por lo que se utilizó un proceso de cálculo aleatorio. Programando las peores condiciones tolerables, se obtuvo una gran coherencia (es decir, correlación: R2 = 0.991, y una diferencia de error de 10 %) entre la simulación numérica y un modelo estadístico y además se determinó la fuerza promedio de las piernas y su desviación estándar: 98 ± 27 N (error porcentual: 28 %), de modo que la fuerza máxima de las piernas (y de baja probabilidad) es de 3σ = 182 N. Así, considerando la masa neta, la fuerza máxima del movimiento es 758 N. Esta información se contrastó, sin contradicción, con la literatura sobre deportes de contacto. Se muestra a detalle que una adecuada acotación de números aleatorios en una ecuación determinística permite enmendar la falta de información en casos videograbados, de modo que se puede optimizar la estimación del intervalo de incertidumbre cuando los datos de medición son poco confiables.

Pavement Bases from Recycled Materials
Authors: Кayumov A. К. , Zinevich S. I. , Kovalev Y. V.
Published: December 2022

Road bases are the main bearing layers of the road pavement, the purpose of which is the perception of the load from cars and its distribution on the subgrade soil. The base structure is determined by calculation depending on the planned traffic load and traffic intensity and usually consists of two layers, and for capital coatings, the upper layer of the two-layer base is made of materials reinforced with binders. The base of the pavement is a rather expensive construction and it is important for its construction, where possible, to use local materials, as well as secondary materials, i. e. industrial and construction industry waste.  In the process of construction and repair works, the use of secondary raw materials can significantly reduce the cost of their implementation. Moreover, this practice not only reduces the cost of work, but also reduces the negative impact on the environment. The paper considers the possibility of constructing a pavement base from such secondary materials as spent molding sands (foundry waste), cement granulate (a product of crushing old cement concrete structures, construction waste) and asphalt granulate (a product of milling worn asphalt concrete pavements). In this case, the cost of the base is significantly reduced  while еnsuring its necessary strength. Spent sands were used as a leveling layer, cement granulate

Durante muchos años, la agricultura en las zonas alto andinas del Perú no ha presentado mejora tecnológica, sino se ha convertido en agricultura dependiente de agroquímicos, lo que está provocando que los suelos estén perdiendo productividad, obligando al agricultor a un uso excesivo de agroquímicos o abandonar estos suelos y buscar otros para continuar usándolos. En el presente trabajo experimental, se busca identificar si las diferencias en los parámetros físico-químicos y biológicos del suelo abandonados mediante el entierro de plantas vivas, técnica conocida como incorporación de abonos verdes. Las especies que se usaron en la investigación fueron Trifolium pratense L.(T1) Lolium multiflorum L. (T2), la asociación entre las especies Trifolium pratense L. y Lolium multiflorum L. (T3) y el control (Control). Al ser incorporadas o enterrada las especies en el suelo, se buscó identificar qué cambio generaban en el suelo y si es eficiente esta técnica para generar un cambio en la estructura química y biológica del suelo. El proceso de investigación inició en febrero del 2021, las muestras de suelo fueron tomadas en tres tiempos, la primera en febrero, la segunda toma muestra en el mes de mayo y la última muestra en junio. En la primera toma, se obtuvo el resultado del estado del suelo, en la segunda toma de muestra, el parámetro que resultó significativo fue el parámetro biológico (respiración microbiana), el cual presentó un cambio significativo entre los tratamientos y el control. La respiración microbiana - CO2 (mg/g*h), fue 0.106 mg/g*h, para el T1, para el T2 fue 0.088 mg/g*h, y para T3 fue 0.090 mg/g*h, mientras el control fue 0.006 mg/g*h. Este resultado muestra un incremento en la actividad microbiana cuando el suelo presenta una cobertura verde, que fueron los tratamientos, debido a que esta brinda humedad y ayudan a la regulación de...
The good, the bad, and the blameless: A thematic analysis of the parental role in childhood obesity on an Internet discussion board
Authors: Koivumäki Terhi , Jallinoja Piia
Published: December 2022

Background
Childhood obesity affects an increased percentage of families globally. For families, obesity is often a tense issue, not least because of the negative stigma and cultural perceptions associated with it. Discussions around childhood obesity do not take place only at homes or in health care, but increasingly on social media, such as Internet discussion forums. On these platforms, parents, including those having a child with obesity, are exposed to cultural ways of framing childhood obesity, and defining who is responsible for children’s weight.
Method
We gathered and analysed 16 discussion threads on childhood obesity taken from a Finnish internet discussion forum, vauva.fi, between 2015 and 2021 (a total of 331 posts). For the analysis, we chose threads where parents having a child with obesity took part. The data were analysed and interpreted with inductive thematic analysis.
Results
In the online discussion on childhood obesity, the posts were mostly about the reasons and solutions for obesity, and obesity was discussed in the context of parental responsibility and lifestyle choices within the family. We located three themes that were used to define parenthood: being a good parent, being a bad parent, and being a blameless parent. Parents listed healthy elements in their family’s lifestyle to prove their good parenthood, whereas other commenters frequently tried to point out mistakes in the parents’ behaviour or offer advice. Moreover, many acknowledged that some factors causing childhood obesity were outside the parents’ influence. In addition, many parents brought up that they were genuinely ignorant of the reasons for their child’s overweight.
Conclusions
Our results showed that for the parents and other commentators childhood obesity is not only a question of weight and lifestyle changes. Instead, defining good of parenting and related tasks was a recurring theme in the discussions. Consequently, counselling for parents in health care should be expanded from supporting a healthy lifestyle to strengthening parents’ identity as being good enough parents. Furthermore, efforts should be made to increase parents’ self-efficacy. In addition, supporting parents to accept and process feelings related to the child’s weight would help them to adapt to their situation.
A novel authentication scheme for group based communication for IoT oriented infrastructure in smart cities

Published: December 2022

As a result of the rapid developments in digital technologies, smart cities have been adorned with several digital gadgets based on the Internet of Things (IoT). The essential part of smart city operations is IoT communications. IoT devices generate, process, and exchange a large amount of security-critical and privacy-sensitive data regularly, resulting in attractive targets for threats and attacks. Group-oriented communication, such as data gathering and area monitoring, is critical in the IoT World. It enables users to manage various IoT devices simultaneously. Conventional one-to-one authentication techniques donot consider the resource constraints of IoT devices in grouped communication. They also do not solve the issue of massive machinecommunication (mMTC) scalability. Many to Many (M2M)authentication approach of group authentication makes grouporientedcommunication and mMTC very secure. The lower timecomplexity of Group-based authentication (GBA) makes theseprotocols very popular for efficient and secured communication.This paper uses a polynomial-based group authentication schemeand membership verification to ensure efficient and threat-freecommunication among IoT devices. Bi-variate polynomials havebeen used instead of single variable functions in the proposedscheme. The protected nature of the bi-variate polynomial makesthe proposed scheme very secure and reliable. Furthermore,establishing the session key makes the proposed scheme effectiveand efficient. Security analysis of the proposed work shows itsefficiency over existing schemes.

Late-onset Fuchs endothelial corneal dystrophy (FECD) is a disease affecting the corneal endothelium (CE), associated with a cytosine-thymine-guanine repeat expansion at the CTG18.1 locus in the transcription factor 4 (TCF4) gene. It is unknown if CTG18.1 expansions affect global methylation including TCF4 gene in CE, or if global CE methylation changes at advanced age. Using genome-wide DNA methylation array, we investigated methylation in CE from FECD patients with CTG18.1 expansions and studied the methylation in healthy CE at different ages. The most revealing DNA methylation findings were analyzed by gene expression and protein analysis. 3488 CpGs had significantly altered methylation pattern in FECD though no substantial changes were found in TCF4 . The most hypermethylated site was in a predicted promoter of aquaporin 1 (AQP1) gene, and the most hypomethylated site was in a predicted promoter of coagulation factor V (F5 for gene, FV for protein). In FECD, AQP1 mRNA expression was variable while F5 gene expression showed a ~23-fold increase. FV protein was present in both healthy and affected CE. Further gene expression analysis of coagulation factors interacting with FV revealed a ~34-fold increase of thrombomodulin (THBD). THBD protein was detected only in CE from FECD patients. Additionally, we observed an age-dependent hypomethylation in elderly healthy CE. Thus, tissue-specific genome-wide and gene-specific methylation changes associated with altered gene expression were discovered in FECD. The age-associated hypomethylation observed in healthy elderly CE might contribute to FECD’ late onset. TCF4 pathological methylation in FECD because of CTG18.1 expansion was ruled out.

The suitability of cement-treated high plasticity graded gravel soils for the construction of road base and sub-base layers is discussed in this paper. The selected high plasticity gravel soils are classified into several levels based on their size, i.e., G50-50& G50-50*, G35-65& G35-65*, G25-75& G25-75*, respectively, to explore the effect of gradation on their strength and durability. The California Bearing Ratio (CBR) test determines the improved CBR % for each gradation when the cement admixture is increased using the partial curing method (3 days wet gunny bags and 4 days water curing). To measure the durability of the mixture, wet and dry tests were performed on all high - plasticity cementitious graded gravel mixtures. As per the test results, the gravel level, plasticity, and curing process directly affect the mixture's strength and durability. According to the test results, high plasticity soils, gradations G50-50& G50-50*, have CBR % values of 96 to 112 & 81 to 102 respectively, with 6–7% of cement addition under partial curing method, which is more than adequate for the base and sub-base layers of road construction as per MoRTH specifications. Scanning electronic microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) analysis revealed a significant amount of ettringite and a higher Si / Ca ratio in the high plasticity graded gravel mixes (HPGG) than in the cement-treated high plasticity graded gravel mixes (CT-HPGG); thus, the cement-treated high plasticity graded gravel soils possess greater strengths and durability.
