Published: June 2022

The thought process needed to formulate problems and solutions so that these solutions can become effective information processing agents in solving problems is called computational thinking (CT). The process of implementing learning using the CT approach is related to those provided by Google for Education, namely abstraction, algorithm design, decomposition, and pattern recognition. CT is a term that refers to the main ideas and concepts in the fields of informatics and computer science, so the proposed Community Service (PkM) activity this time will introduce looping and branching materials. Learning is taught and presented in a fun way, and then activities are carried out that discuss the problems that exist around the students of SMAN 5 Pekanbaru. It is hoped that by injecting the CT concept it can foster students' creativity, foster a culture of information, algorithms, and computational thinking, and involve students in utilizing information technology, computers, and applications from an early age

Russian Byron in the XXI Century: Notes on Modern Translations of Sun of the Sleepless
Authors: Nenarokova Maria R.
Published: June 2022

This work reviews and analyses translations of Byron’s poem Sun of the Sleepless in modern Russia. Fourteen translations of this poem that appeared on the Internet from 2000 to 2021 serve as a case study. Of the ten authors, only two are professionally connected with literature. The rest are amateur translators. Analysis of the texts showed that, according to the classification of translations created by R.R. Tchaikovsky and E.L. Lyskenkova, all discovered translations are divided into four groups: translations-variations, translations-modifications, imitations and poems based on the original. Six translations-variations continue the traditions of the Russian translation school, conveying the form and content of the original with varying degrees of accuracy. Translations-modifications are characterized by a greater degree of freedom. They do not convey the form of the original, they make changes to the contents of the original, but their connection with Byron’s text is easily traced. Another group of texts refers to imitation translations: the author created five versions of the text, which are connected with the original only by an attempt to preserve the poetic meter and vocabulary. One more poem can be considered written to the motive of Sun of the Sleepless. The content of these texts differs sharply from the original. Here we can say that reading Byron awakened in the authors the need for their own creativity. A review of translations shows that Byron's lyrics are still in demand in Russia.
Subjective and Objective Orientation in Space by Means of Pronominal Deixis in Danish
Authors: Nikulicheva Dina B.
Published: June 2022

The article focuses on the three-term model of a communicative situation and its role in the restructuring of the system of deictic pronouns in the Danish language. It is argued that in addition to binary oppositions that indicate close (denne, dette, disse) or remote (den, det, de) location of an object in physical space modern Danish develops a three-term opposition of analytical demonstrative pronouns (complex demonstratives), reflecting the interaction between the three participants in a communicative act: the speaker, the listener and the external world. The study of analytical demonstrative pronouns in the Corpus of Modern Danish (Korpus DK) shows that complex demonstratives that combine two indicators of proximal deixis (denne her, dette her, disse her) are used as subjective markers of the 1st person, signaling that the deictic object intrudes into the speaker's personal space. Complex demonstratives that combine indicators of proximal and distal deixis (den her, det her, de her) are used as cohortatives, signaling the compatibility of perception of the deictic object by the addresser and the addressee. Complex demonstratives that combine indicators of the distal deixis (den der, det der, de der) serve as signals of a subjectively withdrawn or alienated object. Thus, the paradigm of complex demonstratives in the Danish language based on the idea of three “spatial belts” is established: the personal space of the speaker (1st person), the common space of communication shared with the addressee (2nd person) and the external space into which the speaker mentally remotes reproved or alienated deictic objects (3rd person).
LncRNA HOTAIR/MiR-217/GPD2 Axis Medicates Hypoxia Injury of Myocardial Cells
Authors: Dai LiHua
Published: June 2022

This study examined impacts of lncRNA HOX Transcript Antisense RNA (HOTAIR), miR-217 and Glycerol-3-phosphate dehydrogenase 2 (GPD2) on progressions of cardiomyocytes after hypoxia damage. Hypoxia treatment induced low cell viability and increased apoptosis. RT-qPCR evaluated suppressed expressions of lncRNA HOTAIR. Overexpressed lncRNA HOTAIR accelerated AC16 cell viability but restrained cell apoptosis and proinflammatory protein expressions while the knockdown of HOTAIR caused opposite results. MiR-217 then was examined to be inhibited by HOTAIR overexpression, whose upregulation reduced AC16 cell viability but facilitated apoptosis and pro-inflammatory protein expressions. Luciferase reporter test then verified that GPD2 was bound and decreased by miR-217, which promoted AC16 cell viability but hampered cell apoptosis and pro-inflammatory protein expressions after overexpression. Moreover, PI3K/AKT signaling pathway was activated by overexpression of GPD2
The Role of Women in Indigenous Conflict Management in the Mokgalwaneng Village in the Moses Kotane Local Municipality, South Africa
Authors: Mboh Lovelyne , Ekobi Gabriel
Published: June 2022

Abstract Women have been occupied with managing conflicts in African indigenous communities. However, their contribution in conflict resolution has not been documented in South Africa. The aim of this qualitative study was to explore the role of women in managing indigenous conflicts in the Mokgalwaneng community. The data were collected from 14 participants from the Mokgalwaneng community by means of semi-structured and unstructured interview guides and thematically analysed. Three main themes were identified: the types of indigenous conflict, causes of indigenous conflict and the role of women in indigenous conflict management in the Mokgalwaneng community. Findings revealed that there are several types of indigenous conflict in the area. Land, domestic, theft and adultery, fornication and rape were raised as the causes of conflict. Women used indigenous conflict management techniques such as accommodating, collaborating and compromising to manage indigenous conflicts in the area. Also, women in the Mokgalwaneng village assisted indigenous institutions of elders and traditional leaders in resolving conflicts. Although women played a role in the indigenous conflict management, they were being marginalised in relation to indigenous conflict management. This study recommended that gender inclusive conflict management policy should be introduced as this might help promote gender equality and alleviate gender bias.

ABSTRACT

Acne is a major problem for teenagers, especially at puberty. Guava leaves (Psidium guajava Linn .) are

plants that contain several secondary metabolites, including the tannins, triterpenoids, glycosides, and

flavonoids, which have anti-acne activity. So far, acne reduction is still being done using synthetic cosmetics.

However, synthetic cosmetics often irritate, so that herbal cosmetics are an alternative. Formulation of

herbal cosmetics for acne need to do. This study aims to determine the best formula for anti-acne cleanser

emulgel from the ethanol extract of guava leaves based on the physical evaluation. Guava leaf extract as

obtained by the maceration method uses ethanol as a solvent, then an emulgel was prepared with an extract

concentration of F1 (5%) and F2 (10%). Emulgel characteristics were determined by physical evaluation

including organoleptic, pH, emulsion type, viscosity, spreadability, homogeneity, foam stability, power clean,

and hedonism. The best formula was determined by the number of tests that meet the requirements and are

liked by consumers. The results had shown F1 is the best formula based on physical evaluation.

ABSTRACTAntioxidants in the ethanolic extract of suji leaves (Pleomele angustifolia) have the potential as a sunscreen. The use of chitosan in the nanoparticle system is able to protect the degradation of flavonoids due to the influence of temperature and light. Tween 80 and cetyl alcohol play a strategic role in the formation of cream preparations. The purpose of this study was to determine the characteristics of sunscreen cream with variations of Tween 80-cetyl alcohol containing the active ingredient of ethanol extract of suji leaves encapsulated in a nanoparticle system. Chitosan nanoparticles of suji leaf ethanol extract (KEEDS) were prepared using ultrasonic agitation. KEEDS nanoparticles were made into cream preparations with variations of Tween 80-cetyl alcohol (T80:SA) FI (3:3)%, FII (3:10)%, FIII (10:10)%. The formed cream was observed for organoleptic, homogeneity, type of cream, and measured the value of pH, spreadability, adhesion, viscosity, and sunscreen activity using a UV-Vis Spectrophotometer at a wavelength of 290–320 nm. Organoleptic data, homogeneity, pH and cream type were analyzed descriptively, while the spreadability, adhesion, viscosity and sunscreen activity were analyzed using ANOVA with 95% confidence limit. KEEDS nanoparticle cream visually looks homogeneous, with a brownish white color, soft texture, and the aroma of suji leaves. The pH value of the preparation is 4.74-4.88, the type of cream is O/W. The variation of the T80:SA combination resulted in significant differences in the values of dispersion, adhesion, viscosity and sunscreen activity between the three formulas (sig < 0.05).Keywords: cetyl alcohol, chitosan, cream, leaves Suji (Pleomele angustifolia), sunscreen, Tween 80

Drying grain requires a large area with heavy work because farmers have to turn the grain that lies on the field every hour and requires a lot of energy because it is done under the hot sun. Drying of grain by farmers involves still checking the level of dryness manually using only the human senses as a measuring tool. One of the drawbacks is that manual checking process is not accurate enough and will affect rice production. So we need an innovation in existing technology to measure the level of drought.This robot is designed in the form of a prototype where the grain mixer system is in the middle. The movement of the robot is only forward and backward which will be controlled using a smartphone by the operator and the width of the grain area to be stirred is 50 cm or along the stirrer. Temperature and humidity sensors will be installed at the bottom which will make it easier to measure the temperature and humidity of the stirred grain making it easier for farmers to monitor the level of grain dryness.

It has been shown that C3H8 is activated on the metal oxide catalysts and C6H6 interacts with the zeolites yielding the C6H7+ intermediate, which acts as an agent of proton transfer from a zeolite to a metal catalyst, and another intermediate C9H13+ . Cumene, alkylbenzenes, and propene are formed as a result of the conversion . Acomparison of the results of the conversion of these mixtures on the composite catalysts with different zeolites shows that the formation of cumene and propene is thermally controlled and the formation of the other products is kinetically controlled. It has been concluded that the coupling of the redox properties of the metal oxide catalysts with the acid–base properties of the zeolite catalysts facilitates the low–temperature transformations of the C6H6 : C3H8 mixtures.

Authors: Strecker Philip , Boeker Martin , Buechner Simon , Scheible Raphael
Published: June 2022

Medical Subject Headings (MeSH) is one of the most important vocabularies for information retrieval in medical research. It enables fast and reliable retrieval of research on PubMed/MEDLINE, the world’s largest body of medical literature. The original English version of the thesaurus can be accessed via a MeSH Browser developed by the NLM. Recently, a multilingual MeSH Browser was proposed to enable usage across languages. To improve upon the original system, a new user interface (UI) was developed using contemporary web design frameworks in combination with principles from cognitive science. It aims to simplify access for medical professionals and increase overall usability. Evaluating such design improvements continually is necessary to quantify the possible positive impact for online systems in medical research. This study therefore directly compares the resulting system to the NLM Browser, using an established online questionnaire. Results show significant improvements in content and navigation as well as overall user satisfaction, while offering feedback for future improvements. This underlines the benefits of employing contemporary web design in terms of usability and user satisfaction.

Visualization System for the Impact of Context Open Data in Clinical Settings
Authors: Alonso Eduardo , Garcia-Navarro Teresa , Larburu Nekane
Published: June 2022

The usage of context open data, such as environmental data, socio-economic resources, etc., in clinical settings has been limited till now. But in recent years the number of studies that consider these factors is increasing. However, for clinicians, researchers or other stakeholders to be able to use this information in clinical practice, appropriate visualizations tools must be developed. At the same time, the data are generally displayed in formats that are difficult to interpret. The use of geolocalized visualizing tools through maps provides a better understanding in most cases. The proposed tool aims to contribute to the development of systems that can help to the exploitation of clinical and context open data, making them more easily interpretable.

Published: June 2022

Visualizations form an important part of public health informatics (PHI) communications. Visualizing data facilitates discussion, aids understanding, makes patterns apparent, promotes analysis, and fosters recall. How rare are novel visualizations in the PHI literature? In Phase 1, we used a rapid review methodology to test the commonness of the Sankey diagram in the PHI theory literature via an automated text search for key terms. In Phase 2, we prototype an uncommon chart type. A total of 27 relvant papers were searched and a computer-generated Sankey diagram was prototyped. PHI professionals have access to visualization tools emerging from social media and niche systems. PHI literature underutilizes uncommon visualizations requiring programming expertise. The authors advocate for: multi-disciplinary teamwork, technical education, the use of open visualization tools, and further adoption of visualization for public health professionals.
A Systematic Review on Improving Health Literacy in Rural Africa Using Mobile Serious Games
Authors: Ouedraogo Ismaila , Some Michel J. , Benedikter Roland , Diallo Gayo
Published: June 2022

Driven by an increase in the availability of cheap low-cost mobile phones and a jump in the number of telecom subscribers, the African gaming world is booming. Most importantly, it has opened an opportunity for rural communities to have an almost identical mobile phone experience than people living in urban areas. It has also opened an opportunity to leverage this high penetration of mobile devices to design mobile-based applications such as mobile serious games. The latter assists individuals living in these communities to modify, change or shape their behaviors and attitudes desirably. This paper reviews mobile serious games in healthcare education, especially those intended to improve health literacy in rural Africa. The challenges and issues encountered in the design and use of persuasive mobile games as a tool can promote behavior change among people living in the rural African communities.

Authors: Joseph Amanda L. , Monkman Helen , Kushniruk Andre W.
Published: June 2022

The journey map concept evolved out of the service design field and is still relatively new in the healthcare landscape [1]. Journey maps are visualizations that effectively highlight organizational issues and allow stakeholder groups to be depicted by interest or function for a comparative visual analysis [2]. There are five journey map approaches: 1) Mental (Cognitive) Model Map, 2) Customer Journey Map, 3) Experience Map, 4) Service Blueprint Map, 5) Spatial Map. The objective of this article is three-fold: 1) quantify and delineate the journey mapping visualization techniques utilized from the phase 1 scoping review [2], 2) create a Journey Map Evaluation Guide, 3) create a Journey Map Decision Support Tool to facilitate a standardized method for journey map selection. For those less familiar with journey mapping, this framework can serve as a decision-making tool to facilitate the most effective choice among the different journey mapping visualization approaches. The tools presented in this study can provide a mechanism to standardize the assessment, classification and utilization of journey maps in the healthcare sector and industries abound.

Rural women in developing countries do not have any option but to visit the distant city to see the obstetricians and gynecologists in case of any maternal and child health issues. However, it becomes more difficult to travel during the COVID-19 pandemic situation. Thus, the telehealth service using the Portable Health Clinic can be very effective for maternal and child health care services. Since the PHC system provides home delivery services through the local health workers, the rural women can avail regular continuum of care services. This study found a 300% increase in participation in the continuum of care. This is not because they receive the service at home but also because they can receive consultancy from urban specialist doctors without travel during the pandemic situation.
Health-Related Content in Transformer-Based Deep Neural Network Language Models: Exploring Cross-Linguistic Syntactic Bias
Authors: Samo Giuseppe , Bonan Caterina , Si Fuzhen
Published: June 2022

This paper explores a methodology for bias quantification in transformer-based deep neural network language models for Chinese, English, and French. When queried with health-related mythbusters on COVID-19, we observe a bias that is not of a semantic/encyclopaedical knowledge nature, but rather a syntactic one, as predicted by theoretical insights of structural complexity. Our results highlight the need for the creation of health-communication corpora as training sets for deep learning.
