Navigating Diversity in Plural Indonesia
Authors: Akun Andreas
Published: May 2023

The research aimed to show the supposedly unquestionable national slogan ‘Unity in Diversity’. It still got severe challenges today, as proven by the rise of religious, political, and psychological underpinnings of intolerance surrounding the 2019 presidential election, politically dividing Indonesian into pros or cons of NKRI (Negara Kesatuan Republik Indonesia or The United Nations of Indonesia). This was a reader response research of EnglishDepartment students using short stories to gather their perspectives on the role of Multicultural Literature (ML).The short stories were taken from internationally recognized authors from Indonesia, the USA, Japan, France, China, and Egypt. Questionnaires and interviews were used to intensively collect the participants’ experiences and ideas. The results of the research show that diversity problems are identified, and solutions are proposed through the literary learning curriculum design and process. It also shows the need to promote multicultural literature practice for English department students. The mastery of Multicultural Literary Competence is finally proposed as one of the golden goals of Indonesian national education, where diversity is the true color of Indonesia to easilyequip graduates to become global citizens. Today’s interconnected, globalized world has required millennials to possess CQ (Cultural Quotient) regardless of their diverse background. This CQ can effectively be cultivated through multicultural literature in a multicultural education system. Only through mastering CQ cultivated through ML are Indonesian graduates ready to enter the global and digital competition as global citizens.

Authors: Oktiani Yufita Ria , Putri Evi Jovita
Published: May 2023

The research examined the persuasive strategies employed in selected UNICEF speakers’ speeches (BTS - RM and Jin, Millie Bobby Brown, and David Beckham). The observation aimed to determine the types of persuasive strategies used in selected UNICEF speakers’ speeches and how they were implemented. The research employed a descriptive qualitative approach in its research design. In the data analysis process, the analysis was conducted by describing and interpreting each data point in the form of words or utterances according to the context. A purposive sampling of all facts was used to collect data. In addition, the research used Aristotle’s theory of persuasion as a reference to help understand and analyze the data found from the speech. According to the data analysis, the research discovers 49 data points that utilize persuasive strategies. They employ all of Aristotle’s persuasive strategies to persuade their audience. These are the strategies of ethos, pathos, and logos. In their speeches at the children’s day event, BTS, and David mostly express pathos, while Millie mostly expresses logos. It proves that by expressing their credibility, serving realistic information, and including the hearer’s emotions in their speech, UNICEF speakers intentionally attempt to achieve their purpose.
Development of an Evaluation Checklist for Localized Chinese Language Textbooks in Sri Lanka
Authors: Dassanayake Noel
Published: May 2023

The research analyzed the limitations of existing Chinese language textbooks in Sri Lanka and proposed a tentative checklist for evaluating localized Chinese language textbooks. The discourse on the effectiveness of global textbooks in local contexts and the need for evaluating such textbooks had seen new paradigm shifts in parallel to the transformations in new language environments. A majority of the institutes and programs teaching Chinese as a Foreign Language in Sri Lanka were using global CFL textbooks as their main study material, and their effectiveness had not yet been evaluated by researchers. The research conducted a quadruple perspective analysis, including an online survey with learners and teachers to examine the issues in existing CFL textbooks, a review of existing literature on textbook evaluation, an analysis of existing CFL textbooks in Sri Lanka, and an examination of existing language textbook evaluation criteria. The findings of the survey indicate that global textbooks have not catered to the specific language requirements of the informants. Insensitivity to the local and regional cultural content, minimal utilization of learners’ L1 repertoire, ambiguous inapt translation of vocabulary, and market-oriented presentation of teaching-learning content is found to be core issues, and high pricing and inaccessibility also are influential issues. Based on the quadruple perspective analysis, the research has developed a tentative evaluation checklist of 37 items with a specific emphasis on localization and culture sensitivity.
Optimal Control in a Multiagent Opinion Dynamic System
Authors:   St. Petersburg State University, Gao Jingjing , Parilina Elena ,   St. Petersburg State University
Published: May 2023

The paper considers a multiagent system of opinion dynamics modeling a finite social network opinion transformation. In the system, there is an influencer or a player who is interested in making the agents' opinions in the system close to the target opinion. We assume that the player can influence the system only at a limited number of time periods. The player minimizes his costs by selecting moments to control the multiagent system at these moments, while at any time period he observes the agents' opinions. The optimization problem is solved using the Euler-equation approach. The numerical simulations represent the proposed method of finding the optimal solution of the problem.
Tax Authority and Taxpayers: How Does Mutual Collecting of Information Affect the Effectiveness of Tax Control
Authors:   St. Petersburg State University, Kumacheva Suriya Sh. , Tomilina Galina A. ,   EPAM Systems
Published: May 2023

Lots of works have been devoted to the modelling of tax control. In the classic game-theoretic formulation, the subject of study is the interaction between tax authority and taxpayers. However, along with such attitude to the problem, some works allow us to study auxiliary problems related to tax collection and tax control. Two of these issues are worth mentioning. The first is the dissemination of information about future tax audits among the taxable population. The second is the gathering and analysis of information on the tendency of taxpayers to evasion. It was shown that both processes can be used to adjust the tax authority's strategy and optimize audits in order to improve tax collection. However, the mutual collecting of information on tax audits by the taxpayers and the tax authority decreases the total tax revenue. The study of formulated problem is accompanied by the modelling of both processes, their simulation, and comparative analysis of the results.

The problem of dividing the community into groups of related participants has been solved, an appropriate algorithm for finding the most influential community agents has been proposed. Clustering was carried out using an algorithm for reducing the adjacency matrix of a directed graph with nodes representing members of a social network and edges representing relationships between them. The applications to the problems of working groups, advertising in social networks and complex technical systems are considered.
Existence of Stable Coalition Structures in Three-player Games with Graph-constrained Solution
Authors:   St. Petersburg State University, Sun Ping
Published: May 2023

The stability of coalition structures is investigated in the sense that no player prefers to individually deviate from the current coalition considering his utility. This principle is close to the concept of the Nash equilibrium. The evaluation of each player's utility is determined with respect to the solution concept- the Shapley value with exogenous directed graph constraint. The existence of a stable coalition structure with respect to such a solution is examined for two-player as well as three-player games.
Concept of Social Value Orientation in Measuring Cooperative Behavior Incentive in Games
Authors:   St. Petersburg State University, Xia Yuyan , Li Yin ,   St. Petersburg State University,   Harbin Institute of Technology
Published: May 2023

The purpose of this study is to explore the effects and mechanisms of cooperation indicators such as interpersonal trust, social preferences, and social value orientations on cooperative behavior, and we develop a psychologically grounded model of trust-based cooperation. Some accounts of cooperation in product choice games have focused on developing simple indicators of game severity i.e., the extent to which the game facilitates noncooperative choices that are derived exclusively from the game's payoff structure. However, this approach does not provide a clear explanation of the psychological mechanisms why the game's payoffs affect the rate of cooperation. When considering individuals' social preferences and positive expectations (beliefs) for how to predict the emergence of trust-based cooperation as an expected utility maximizing strategy, we show a simple decision model for trust-based cooperation. In addition, we show how these predictions are associated with a game-specific cooperation index. We then describe under what conditions trust-based cooperation is rationalizable and how trust-based decisions can be understood through the interplay between of payoffs, preferences, and beliefs.
Una razón existencial y personal: aprehensión y asentimiento en John Henry Newman
Authors: Briones Rodrigo
Published: May 2023

John Henry Newman (1801-1890), quien ha ejercido una enorme influencia intelectual en el desarrollo de la teología católica contemporánea, es menos conocido por sus aportes a la filosofía. Indagando en su principal obra filosófica, Un ensayo para contribuir a una gramática del asentimiento, intentamos mostrar cómo los conceptos de aprehensión y asentimiento reflejan una teoría del conocimiento de carácter existencial y personal, en clara confrontación con el racionalismo imperante de su época. A través del examen de tales nociones, en el entramado conceptual no fácil de la Grammar, pretendemos justificar que son muchos los elementos por los que Newman puede ser considerado plenamente un filósofo, en cuanto contribuye significativamente a una gnoseología y antropología personalistas.
Protective Effects of Curcumin and its Analogues via the Nrf2
Pathway in Metabolic Syndrome
Authors: Rajabi Shahnaz , Darroudi Majid , Naseri Kobra , Farkhondeh Tahereh , Samarghandian Saeed
Published: May 2023

Metabolic Syndrome (MetS) refers to a set of medical conditions including insulin
resistance, central obesity, atherogenic dyslipidemia, and hypertension. Due to these
dysregulations, if not treated, MetS could increase the risk of CVA, CVD, and diabetes.
As described by WHO, CVD is the leading cause of mortality in the world which
motivates researchers to investigate the management of its risk factors, especially MetS.
It is reported that oxidative stress secondary to the abundant generation of free radicals
oxygen species (ROS) and the ensuing altered redox status play an important role as a
mediator in MetS. As a result, using new antioxidant agents with higher bioavailability
has been proposed as an efficient treatment.

:

Curcumin (a polyphenol of the diarylheptanoids class), which is used as a traditional
medicine for various diseases including cardiovascular diseases and diabetes, is characterized
by its antioxidant properties which, at least in part, are mediated via the activation of
the Nrf2/ARE signaling pathway. Nrf2 is a transcription factor that plays a key role in
regulating internal defense systems and increases antioxidant levels to decrease oxidative
damage and cell apoptosis. Nrf2 expression and stability are enhanced by curcumin, leading
to a higher rate of Nrf2 migration to the cell nucleus to regulate ARE gene expression,
thus protecting cells against oxidative stress. In this article, we provide a comprehensive
review of the molecular effect of curcumin and its derivatives via Nrf2 regulation
in several conditions, such as diabetes, hypertension, dyslipidemia, and obesity.
Exploring the Potential Mechanism of Action of Ursolic Acid against Gastric Cancer
and COVID-19 using Network Pharmacology and Bioinformatics Analysis
Authors: Liu Zhiyao , Huang Hailiang , Yu Ying , Jia Yuqi , Li Lingling , Shi Xin , Wang Fangqi
Published: May 2023

Background:

Patients with gastric cancer (GC) are more likely to be infected with 2019 coronavirus
disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the prognosis
is worse. It is urgent to find effective treatment methods.

Objective:

This study aimed to explore the potential targets and mechanism of ursolic acid (UA) on GC and
COVID-19 by network pharmacology and bioinformatics analysis.

Methods:

The online public database and weighted co-expression gene network analysis (WGCNA) were used
to screen the clinical related targets of GC. COVID-19-related targets were retrieved from online public databases.
Then, a clinicopathological analysis was performed on GC and COVID-19 intersection genes. Following
that, the related targets of UA and the intersection targets of UA and GC/COVID-19 were screened. Gene Ontology
(GO) and Kyoto Encyclopedia of Gene and Genome Analysis (KEGG) pathway enrichment analyses
were performed on the intersection targets. Core targets were screened using a constructed protein-protein interaction
network. Finally, molecular docking and molecular dynamics simulation (MDS) of UA and core targets
were performed to verify the accuracy of the prediction results.

Results:

A total of 347 GC/COVID-19-related genes were obtained. The clinical features of GC/COVID-19 patients
were revealed using clinicopathological analysis. Three potential biomarkers (TRIM25, CD59, MAPK14)
associated with the clinical prognosis of GC/COVID-19 were identified. A total of 32 intersection targets of UA
and GC/COVID-19 were obtained. The intersection targets were primarily enriched in FoxO, PI3K/Akt, and
ErbB signaling pathways. HSP90AA1, CTNNB1, MTOR, SIRT1, MAPK1, MAPK14, PARP1, MAP2K1,
HSPA8, EZH2, PTPN11, and CDK2 were identified as core targets. Molecular docking revealed that UA
strongly binds to its core targets. The MDS results revealed that UA stabilizes the protein-ligand complexes of
PARP1, MAPK14, and ACE2.

Conclusion:

This study found that in patients with gastric cancer and COVID-19, UA may bind to ACE2, regulate
core targets such as PARP1 and MAPK14, and the PI3K/Akt signaling pathway, and participate in antiinflammatory,
anti-oxidation, anti-virus, and immune regulation to exert therapeutic effects.

Neurological Disorders
Authors: Agrawal Neetu , Bhardwaj Aditya , Singh Sonia , Goyal Ahsas , Gaurav Anand
Published: May 2023

The role of medicinal plants has been advantageous due to their manifestation through
various cellular and molecular mechanisms. Inhibition of the monoamine oxidase enzyme is suspected
to be a highly effective treatment for various neurological illnesses like Alzheimer's disease,
Parkinson’s disease, depression, social phobia, and panic disorders. The study of phytochemicals
and plant extracts used as a traditional source of medication revealed that they possess the vast potential
for monoamine oxidase inhibition. Thus, the article focuses on the potential use of plant extracts
and phytochemicals as sources of novel MAO inhibitors for treating neurological disorders.
Exhaustive literature search revealed that a variety of phytochemicals from the categories such as
flavonoids, alkaloids, glycosides, alkyl phenyl ketones, coumarin derivatives and essential oils
have displayed potential MAO inhibition. This review highlights the progress made in the discovery
and development of plant-based MAO inhibitors and aims to provide medicinal chemists with
an overview of this information to aid in the development of clinically viable drugs.
A Novel Combined Model to Predict the Prognosis of COVID-19: Radiologicalmetabolic
Scoring
Authors: Zorlu Seray Akçalar , Öz Ayşegül
Published: May 2023

Aims:

To investigate the performance of a novel radiological-metabolic scoring (RM-S) system to predict mortality and intensive care unit (ICU)
requirements among COVID-19 patients and to compare performance with the chest computed-tomography severity-scoring (C-CT-SS). The RMS
was created from scoring systems such as visual coronary-artery-calcification scoring (V-CAC-S), hepatic-steatosis scoring (HS-S) and
pancreatic-steatosis scoring (PS-S).

Methods:

Between May 2021 and January 2022, 397 patients with COVID-19 were included in this retrospective cohort study. All demographic, clinical and
laboratory data and chest CT images of patients were retrospectively reviewed. RM-S, V-CAC-S, HS-S, PS-S and C-CT-SS scores were
calculated, and their performance in predicting mortality and ICU requirement were evaluated by univariate and multivariable analyses.

Results:

A total of 32 (8.1%) patients died, and 77 (19.4%) patients required ICU admission. Mortality and ICU admission were both associated with older
age (p < 0.001). Sex distribution was similar in the deceased vs. survivor and ICU vs. non-ICU comparisons (p = 0.974 and p = 0.626,
respectively). Multiple logistic regression revealed that mortality was independently associated with having a C-CT-SS score of ≥ 14 (p < 0.001)
and severe RM-S category (p = 0.010), while ICU requirement was independently associated with having a C-CT-SS score of ≥ 14 (p < 0.001) and
severe V-CAC-S category (p = 0.010).

Conclusion:

RM-S, C-CT-SS, and V-CAC-S are useful tools that can be used to predict patients with poor prognoses for COVID-19. Long-term prospective
follow-up of patients with high RM-S scores can be useful for predicting long COVID.
A Randomized Comparison of Transradial and Transfemoral Approach in
Hepatic Arterial Infusion Chemotherapy
Authors: Li Basen , Li Qin , Peng Ling , Xiang Kun , Xu Anhui
Published: May 2023

Introduction:

Hepatic arterial infusion chemotherapy (HAIC) has been popular for treating unresectable hepatocellular carcinoma (HCC). However, there are few reports comparing the transradial approach (TRA) and transfemoral approach (TFA) in HAIC.

Objective:

This study aimed to compare the duration of the hepatic artery catheterization, fluoroscopy time (FT), radiation exposure, safety, and quality of life associated with the procedure in patients undergoing HAIC via TRA and TFA.

Methods:

This prospective, single-center, randomized, controlled study included 120 patients with unresectable HCC undergoing HAIC procedures. Patients were randomly assigned to group A (n = 60, TRA-HAIC) or group B (n = 60, TFA-HAIC). The hepatic artery catheterization time, FT, entrance surface dose (ESD), dose area product (DAP), procedure-related complications, and quality of life associated with the procedure were assessed between the two groups. Independent-sample t-test and analysis of variance (ANOVA) were used to assess differences. Statistical significance was set at P < 0.05.

Results:

HAIC procedures were successfully performed in both groups. The hepatic artery catheterization time (19.35 ± 5.84 vs. 18.93 ± 5.62 minutes, P = 0.837), FT (2.35 ± 2.23 vs. 2.25 ± 2.16 minutes, P = 0.901), ESD (259.32 ± 167.46 vs. 250.56 ± 170.58 mGy, P = 0.449), and DAP (125.37 ± 60.65 vs. 120.56 ± 64.33 Gy.cm3, P = 0.566) were comparable between the two groups. The incidence of artery occlusion (10.0% vs. 0%, P < 0.001) in the TRA group was significantly higher than that in the TFA group. TRA was associated with a statistically significant (P < 0.05) improvement in the quality of life.

Conclusion:

TRA to HAIC was associated with greater improvement in the quality of life associated with the procedure compared with TFA. Both approaches to HAIC had similar efficiency, safety, radiation exposure, and procedure duration.
Contrast-enhanced Ultrasound of Xanthogranulomatous Endometritis: A Case
Report and Literature Review
Authors: Wu Hailan , Liu Juan , Chen Li , Peng Juan
Published: May 2023

Introduction::

Xanthogranulomatous endometritis (XGE) is a rare inflammatory disease, which can easily misdiagnose as cancer in imaging diagnosis. Diagnosis
of XGE relies on histopathological examination and immunohistochemistry.

Case Presentation:

In this study, a case of a 72-year-old female with XGE and elevated CA125 is presented, which was misdiagnosed as endometrial cancer in
transvaginal ultrasonography and ovarian cystadenocarcinoma in CT. However, the features of XGE on the contrast-enhanced ultrasound (CEUS)
were different from that of endometrial cancer. The patient finally underwent laparoscopic hysterectomy and bilateral adnexectomy.

Discussion::

The histopathological examination and immunohistochemistry suggested xanthogranulomatous endometritis (histiocytic endometritis). This case
report manifests that CEUS may be a new noninvasive diagnostic method for XGE, which may reduce extensive tissue sampling and unnecessary
hysterectomies for patients.

Published: May 2023

Aims:

This study aimed to isolate and identify the Streptococcus spp. bacteria from patients with dental caries infection. Furthermore, the antibacterial activity of new plant extracts on isolated Streptococcus spp. was also evaluated.

Methods:

A total of 150 samples were obtained at random from people of various ages and genders who were suffering from dental caries infection. Four different culture media were used for isolation: nutrient agar, MacConkey agar, blood agar, and Streptococcus selection agar. The identification of bacterial isolates was distinguished by macroscopic examination and the VITEK 2 system.

Results:

Only 120 cases (80%) showed positive culture, and these were distributed as follows: Streptococcus sanguinis had the highest rate and accounted for 38.33%, and Streptococcus pseudoporcinus represented only 29.16%. A 20% decline was reported for Streptococcus salivarius, with the lowest proportion being 12.5% for Staphylococcus warneri. The MIC for 16 tested plant extracts ranged from 0.97 to 125 µg/mL, whereas the MBC values ranged from 3.9 to 500 µg/mL. Imipenem was a positive control, with MIC values ranging from 3.9 µg/mL to 15.6 µg/mL; the MBCs varied from 31.2 to 125 µg/mL against all isolated species.

Conclusion:

Among the isolated bacterial species from tooth decay, Streptococcus sanguinis had the highest rate of isolated bacteria and accounted for 38.33%, while Staphylococcus warneri had the lowest percentage at 12.5%. Sargassum, Proskia, and Cicer arietinum were three distinct extracts that demonstrated superior antibacterial activity against all of the tested bacterial species. Their MIC values ranged from 0.97 µg/mL to 15.6 µg/mL, and the MBC values were between 3.9 µg/mL and 31.2 µg/mL.

Authors: Wan Rong , Shen Shien , Xiao Wenqin , Jiang Weiliang , Li Kai , Guo Xingya , Zong Guanzhao , Wang Chuanyang , Bao Jingpiao , Chen Jiahui , Cheng Zhiyuan , Shen Jie
Published: May 2023

Aim:

In the present study, we aimed to investigate the effects of Fenbufen treatment on the SAP model induced by caerulein and lipopolysaccharide.

Background:

Severe acute pancreatitis (SAP) is an extremely dangerous disease with high mortality, which is associated with inflammatory response and acinar cell death. The caspase family plays an important role in cell death, such as caspase-1 and caspase-11 in pyroptosis. In recent years, caspases have been shown to be a novel pharmacological target of Fenbufen.

Objective:

Effects of Fenbufen on pancreatic tissue damage and serum levels of lipase and amylase in SAP in mice; Effect of Fenbufen on caspase-1 pathway in SAP in mice; Effect of Fenbufen on caspase-1/caspase-11-mediated pyroptosis of PACs in SAP in mice; Effect of Fenbufen on isolated PACs and caspase-1/caspase-11-mediated pyroptosis in vitro.

Methods:

In vivo, eighteen female C57BL/6 mice were randomly divided into 3 groups: the NC group, the SAP group, and the Fenbufen +SAP group with 6 mice in each group. The SAP model was induced by intraperitoneal injection of caerulein and lipopolysaccharide. The pathological changes in pancreatic and the serum levels of lipase and amylase and the relative gene and protein expressions in each group were compared. In vitro, pancreatic acinar cells were assigned to 5 groups: medium group, SAP group, Fenbufen 100μM group, Fenbufen 200μM group, and Fenbufen 400μM group. The cell damage and the relative gene and protein expressions in each group were evaluated.

Results:

Our results showed that Fenbufen ameliorated the severity of SAP and decreased the serum levels of lipase and amylase. Meanwhile, the in vivo and in vitro data demonstrated that Fenbufen inhibited the activation of caspase-1 and caspase-11, decreasing the levels of IL-1β, IL-18, and GSDMD. In in vitro experiments, we found that by inhibiting the activation of caspase-1 and caspase-11, Fenbufen significantly reduced lactate dehydrogenase (LDH) excretion by acinar cells.

Conclusion:

In general, our data showed that Fenbufen could protect the pancreatic acinar cell from injury by inhibiting pyroptosis.

Authors: Zhang Hongxin , Jin Hui , Ma Shaowei
Published: May 2023

Background:

SLAM plays an important role in the navigation of robots, unmanned aerial
vehicles, and unmanned vehicles. The positioning accuracy will affect the accuracy of obstacle
avoidance. The quality of map construction directly affects the performance of subsequent path
planning and other algorithms. It is the core algorithm of the intelligent mobile application. Therefore,
robot vision slam has great research value and will be an important research direction in the
future.

Objective:

By reviewing the latest development and patent of Computer Vision SLAM, this paper
provides references to researchers in related fields.

Methods:

Computer Vision SLAM patents and literature were analyzed from the aspects of the
algorithm, innovation, and application. Among them, there are more than 30 patents and nearly 30
pieces of literature in the past ten years.

Results:

This paper reviews the research progress of robot visual SLAM in the last 10 years, summarizes
its typical features, especially describes the front part of the visual SLAM system in detail,
describes the main advantages and disadvantages of each method, analyses the main problems in
the development of robot visual SLAM, prospects its development trend, and finally discusses the
related products and patents research status and future of robot visual SLAM technology.

Conclusion:

The Robot Vision SLAM can compare the texture information of the environment and
identify the difference between the two environments, thus improving accuracy. However, the current
SLAM algorithm is easy to fail in fast motion and highly dynamic environments, most SLAM
action plans are inefficient, and the image features of VSLAM are too distinguishable. Furthermore,
more patents on the Robot Vision SLAM should also be invented.
Examining the Feasibility, Acceptability, and Effectiveness of Remote Training on Community-Based Participatory Research: Single-Arm Pre-Post Pilot Study (Preprint)
Authors: Fortuna Karen , Bohm Andrew , Lebby Stephanie , Holden Kisha , Agic Branka , Cosco Theodore D , Walker Robert
Published: May 2023

BACKGROUND

Over the past decade, a growing body of scientific evidence has demonstrated that community engagement in research leads to more relevant research, enhances the uptake of research findings, and improves clinical outcomes. Despite the increasing need for the integration of community engagement methodologies into the scientific inquiry, doctoral and master's level competencies in the field of psychiatry often lack dedicated training or coursework on community engagement methodologies.

OBJECTIVE

A total of 13 service users, peer support specialists, caregivers of people with mental health challenges, and scientists (with specialties ranging from basic science to implementation science) aged 18 and older participated in remote training on community-based participatory research. Data were collected at baseline, 2 days, and 3 months.

METHODS

A total of 13 service users, peer support specialists, caregivers of people with mental health challenges, and scientists (with specialties ranging from basic science to implementation science) aged 18 and older participated in remote training on community-based participatory research. Data were collected at baseline, 2 days, and 3 months.

RESULTS

The pilot study demonstrated that a 3-month remote training on community-based participatory research (“Partnership Academy”) was deemed feasible and acceptable by service users, peer support specialists, caregivers of people with mental health challenges, and scientists. Improvements were found in research engagement and the quality of partnership. A marked increase in distrust in the medical system was also found. Groups submitted 4 grant applications and published 1 peer-reviewed journal at a 3-month follow-up.

CONCLUSIONS

This pre- and postpilot study demonstrated it is possible to train groups of service users, peer support specialists, caregivers of people with mental health challenges, and scientists in community-based participatory research. These findings provide preliminary evidence that a 3-month remote training on community-based participatory research (“Partnership Academy”) is feasible, acceptable, and potentially associated with improvements in research engagement as well as the quality of partnership and output, such as manuscripts and grant applications.
Integrative Approaches to Sleep Management in Skin Disease: Systematic Review (Preprint)
Authors: Kulkarni Vishnutheertha A , Mojica Isaiah , Gamsarian Vahram , Tahjian Michelle , Liu David , Grewal Tjinder , Liu Yuyang , Sivesind Torunn E , Lio Peter
Published: May 2023

BACKGROUND

Dermatological conditions, especially when severe, can lead to sleep disturbances that affect a patient’s quality of life. However, limited research exists on the efficacy of treatments for improving sleep parameters in skin conditions.

OBJECTIVE

The objective was to perform a systematic review of the literature on dermatological conditions and the treatments available for improving sleep parameters.

METHODS

A literature review was performed using the PubMed, Ovid MEDLINE, Embase, Cochrane, and ClinicalTrials.gov databases from 1945 to 2021. After filtering based on our exclusion criteria, studies were graded using the SORT (Strength of Recommendation Taxonomy) algorithm, and only those receiving a grade of “2” or better were included.

RESULTS

In total, 25 treatment studies (n=11,025) assessing sleep parameters related to dermatological conditions were found. Dupilumab appeared to be the best-supported and most effective treatment for improving sleep in atopic dermatitis (AD) but had frequent adverse effects. Topical treatments for AD were mostly ineffective, but procedural treatments showed some promise. Treatments for other conditions appeared efficacious.

CONCLUSIONS

The evaluation of sleep parameter changes in dermatological treatments is predominantly restricted to AD. Systemic interventions such as dupilumab and procedural interventions were the most efficacious. Sleep changes in other dermatoses were limited by a paucity of available studies. The inclusion of a sleep assessment component to a broader range of dermatological treatment studies is warranted.
Correlation between Parenting Styles and Learning Stress Junior High School Chinese class Students in Zibo City, China
Authors: Zhang Zihan , Wang Guixia
Published: May 2023

In this study, we investigate the significance of parenting styles in the educational development of junior high school students, recognizing the vital role of family education during this formative period. As the primary educators of their children, parents wield considerable influence on their offspring’s lives, with family education offering distinct advantages over other forms of education. The status and role of family education remain undisputed. Parenting styles encompass a combination of upbringing concepts, behaviors, and emotional expressions toward children. We examine the characteristics and determining factors of different parenting styles, focusing on three typical family upbringing patterns: authoritative, Authoritarian, and democratic. Additionally, we explore the significant impact of these diverse parenting styles on students’ stress levels related to learning Chinese. The paper delves into the essential role of effective and suitable parenting styles in fostering comprehensive and healthy development in students. Furthermore, we elucidate the strategies and methods for establishing positive parenting styles. This quantitative correlational research involved a random sample of 330 participants, collected from three junior middle schools in Zibo City. Utilizing SPSS, we analyzed the relationship between parenting styles and Chinese learning stress among junior high school students
Mesh Optimization using Python Libraries
Authors: Ashok Dr. S. K. , M Dhanush , R Sanjay
Published: May 2023

Abstract: In this project, the mesh of a 3D model is optimised using Python tools (Pymeshlab and Blender python). This is accomplished by the "mesh decimation" procedure, which involves lowering the mesh's total number of triangles. The goal of this procedure is to reduce the complexity of the mesh while preserving the general form and geometry of the original model. The project's main objective is to boost real-time applications' performance, which must provide quick rendering and visualisation. The project attempts to optimise the mesh in order to achieve higher frame rates and better animations, which can enhance the user experience as a whole. It is important to note that the project's main goal is to optimise the mesh without modifying the model's topology or geometry. This indicates that the original structure and shape
Settlement of Square Footing Resting on Geogrid Reinforced Sand and Bottom Ash

Abstract: The concept of soil reinforcement is commonly used in geotechnical engineering. In the past, metallic grid reinforcements were employed to reinforce geotechnical constructions with the concept, but more recently, synthetic reinforcements have been used. Researchers regularly used reinforced sand as a foundation material. However, with the proper reinforcement, other industrial waste products including fly ash, bottom ash, and red mud can also be used as a foundation material because they have a non-plastic nature similar to that of sand. Ash from power plants is considered waste. Geosynthetic reinforced bottom ash is an effective composite material that can be used as a building material for numerous geotechnical engineering applications. Geogrid placed at D/B = 0.5 is found to be more effective than geogrid placed at D/B = 1 and D/B = 1.5. Bottom ash shows less settlement when compared to sand in both reinforced and unreinforced case

Abstract: This work presents an inquiry into Enzyme Induced Calcite Precipitation (EICP) as a way for enhancing the engineering properties of highly plastic soil, in keeping with previous studies on eco-friendly ground improvement methods. The highly plastic soil samples were collected from Kuttanad, Alapuzha. In order to precipitate calcium carbonate (CaCO3) through urea hydrolysis, an equimolar mixture of cementation solution, consisting of urea and calcium chloride along with varying amounts of urease enzyme as catalyst, was added to the collected soil samples. The plasticity, strength, and microstructure of soils will be examined using a variety of tests, including the Atterberg limits test, Unconfined Compressive strength (UCC) testing, and Scanning Electron Microscopy (SEM) analysis. After EICP treatment and 7-day curing, the highly plastic soils showed a significant improvement in their plasticity and strength properties, as evidenced by a decrease in liquid limit and plasticity index, an increase in plastic limit, and a notable improvement in undrained shear strength. The results of the study proves that EICP can be used as an excellent treatment method th improve the plasticity and strength characteristics of highly plastic soils

Abstract: Automated Teller Machines are widely used nowadays by people. But It’s hard to carry their ATM card everywhere, people may forget to have their ATM card or forget their PIN number. The ATM card may get damaged and users can have a situation where they can’t get access to their money. In our proposal, use of biometrics for authentication instead of PIN and ATM card is encouraged. Here, The Face ID is preferred to high priority, as the combination of these biometrics proved to be the best among the identification and verification techniques. The implementation of ATM machines comes with the issue of being accessed by illegitimate users with valid authentication code. This project provides service to the user only when the user is legitimate or the user is verified by the legitimate user of the ATM card. The users are verified by comparing the image taken in front of the ATM machine, to the images which are present in the database. If the user is legitimate the new image is used to train the model for further accuracy. This system uses openCV to process the image being obtained and Haar Cascade Classifier to detect the faces in the image. The face recognition is done using Local Binary Pattern.To overcome these problems,the project ’ATM Security system based on Face recognition, PIN and OTP’ consists of conventional features ie is Personal Identification Number (PIN) along with additional features like face recognition and one-time password (OTP) is used. Database holds information about a user’s account details, images of his/her face and a mobile number which will improve security to a large extent.
Concentration bounds for quantum states and limitations on the QAOA from polynomial approximations
Authors: Anshu Anurag , Metger Tony
Published: May 2023

We prove concentration bounds for the following classes of quantum states: (i) output states of shallow quantum circuits, answering an open question from \cite{DMRF22}; (ii) injective matrix product states; (iii) output states of dense Hamiltonian evolution, i.e. states of the form eιH(p)⋯eιH(1)|ψ0⟩ for any n-qubit product state |ψ0⟩, where each H(i) can be any local commuting Hamiltonian satisfying a norm constraint, including dense Hamiltonians with interactions between any qubits. Our proofs use polynomial approximations to show that these states are close to local operators. This implies that the distribution of the Hamming weight of a computational basis measurement (and of other related observables) concentrates.An example of (iii) are the states produced by the quantum approximate optimisation algorithm (QAOA). Using our concentration results for these states, we show that for a random spin model, the QAOA can only succeed with negligible probability even at super-constant level p=o(log⁡log⁡n), assuming a strengthened version of the so-called overlap gap property. This gives the first limitations on the QAOA on dense instances at super-constant level, improving upon the recent result [BGMZ22].
Modalidades do estranho na poesia de William Butler Yeats
Authors: Manzan Corsi Edson
Published: May 2023

Esta obra tem, como objeto de estudo, três modalidades do estranho na poesia do escritor irlandès William Butler Yeats. São elas: a incidência do Duplo, o contato com os Mortos, o modo de operação deles, tanto no âmbito metafísico quanto no mundo dos Vivos, e o modo de pensar Animista que abarca a onipotência de pensamento. Acreditamos que isso é possível de ser teoricamente pensado e estudado a partir das ideias apresentadas por Sigmund Freud, em seu ensaio "O estranho" ("Das Unheimliche"), publicado em W 19 1919. Para auxiliar nossa discussão do problema, utilizamos algumas considerações do psicanalista francês Jacques Lacan. Por exemplo, o que ele expõe em seu seminário dedicado à angústia e no seu ensaio sobre o "estádio do es pelho". Multas ideais e conceitos importantes de críticos literários como T. S. Eliot, W. H. Auden, Tzvetan Todorov, Emil Staiger, Joseph Warren Beach, Ezra Pound, entre outros, foram também utilizados como base para o desenvolvimento de nossa discussão sobre o tema do estranho, nas fronteiras entre a literatura e a psicanálise. O pensamento de Friedrich Nietzsche também ajudou-nos a entender o conceito que Yeats desenvolveu e usou de "alegria trágica" e a relação do poeta com o pensamento trágico, discutido pelo filósofo alemão e que influenciou a obra do escritor irlandês. Isso possibilitou, na poesia que Yeats escreveu, aparecer um aspecto de absurdidade, de ambição por assimilar-se ao coro da tragédia visível, por exemplo, no capítulo sobre o duplo e que podemos encontrar em seus mais importantes poemas.

This paper aims to determine the impact of the coronavirus disease (COVID-19) on small and medium enterprises in Fiji, which are at risk of crisis. The COVID-19 pandemic exaggerated almost all nations and made small and medium-scale enterprises (SMEs) very vulnerable (Higgins-Desbiolles, 2020). This study recommends policies to stakeholders by reviewing the situation of SMEs in Fiji after the surge of the COVID-19 pandemic. Replies from SME owners were collected and analyzed using descriptive analysis and appropriate graphs. According to the findings, SMEs in Fiji have experienced negative consequences of COVID-19 in the way of shortages of supplies, carriage disruptions, decreased demand for products and services, decreased earnings and sales, inadequate operations, and lockup and staff layoffs. The impact of COVID-19 on SMEs is still being studied, which helps with proactive preparation for the fourth wave of the outbreak (Ashford et al., 2020). The use of samples and quality data set collected using the instrument adds value to the study’s findings and their uniformity. The current body of knowledge in Fiji’s SME sector strengthened the analysis of the sector’s crisis consequences, which has previously gone unnoticed.

Published: May 2023

Software organizations are increasingly embracing the advantages of
Global Software Development (GSD), such as access to highly skilled
developers and reduced development costs. However, the implementation of
Requirement Change Management (RCM) activities in GSD is often hindered
by a lack of communication and coordination among project stakeholders,
as well as an insufficient focus on traceability and monitoring of RCM
activities. To overcome these issues, we have enhanced and improved an
existing RCM framework to mitigate the identified challenges and to
develop a quality product while achieving customer satisfaction and
business objectives. To evaluate the effectiveness of the proposed
Enhanced AZ-Model, we sought feedback from the industrial experts and
performed a statistical analysis of the collected data. The Enhanced
AZ-Model was further validated by performing simulations of the model.
The empirical and simulation results indicate that the Enhanced AZ-model
efficiently and effectively manage the demanded changes according to the
budget and time constraints.

Conventionally, the method of solving fourth-order initial value
problems of an ordinary differential is to first reduce it to a system
of first-order differential equations. This approach affects the
effectiveness and convergence of the numerical method as a result of the
transformation. This paper comprises of the derivation, analysis, and
implementation of a new hybrid block method which is derived by
collocation and interpolation of an assumed basis function. The basic
properties of the block method including zero stability, error
constants, consistency, order, and convergence were analyzed. From the
analysis, the block method derived was found to be zero-stable,
consistent, and convergent. Also, the block method was tested on some
numerical examples and the result computed shows that the derived
schemes are more accurate than existing methods in the literature.
