Clinical Outcomes of Thrombolytic Therapy in Patients with Mild Stroke: Single-Center Experience in a Tertiary Care Institution
Authors: Karadeli Hasan , Simsekoglu Ruken
Published: February 2021

Objective: The term ‘mild stroke’ is used to describe stroke patients
with a NIHSS score of 0 to 6. There is still no clear decision regarding
the application of iv recombinant tissue plasminogen activator (iv-tPA)
to patients who is admitted with an acute ischemic stroke and is in the
mild stroke category. In our study, we aimed to analyze the data of
patients who applied to our stroke center with an acute mild stroke
clinic and received iv-tPA treatment and their three-month follow-up.
Methods: A total of 47 (age 69.1 ± 14.1, 28 female) mild stroke patients
were included out of 350 patients receiving thrombolytic therapy.
Intravenous thrombolysis was initiated with a maximum delay of 4.5 hours
in all patients. Patients had a NIHS score less than 6. NIHSS scores
immediately before starting thrombolytic therapy and scores 24 hours
after treatment were recorded. Modified Rankin Scale scores (mRS) at
admission, 1 and 3 months were recorded. Results: NIHSS scores of the
patients who received tPA decreased significantly after the treatment (p
= 0.001). The patients’ 1st and 3rd month mRS scores were statistically
significantly decreased according to the mRS scores when they entered
the treatment (p = 0.001). Conclusions: This study highlights the
efficacy of iv-tPA in acute ischemic stroke patients with mild symptoms
and demonstrates the low risk profile of this therapy.

In current work, we have firstly synthesized
4-(2-chlorobenzyl)-1-(4-hydroxy-3-
((4-hydroxypiperidin-1-yl)methyl)-5-methoxyphenyl)-[1,2,4]triazolo[4,3-a]quinazolin-5(4H)-one
(1) by ring-opening, cyclization, substitution, doamine condensation and
Mannich reactions. The structural properties of the title compound 1
were explored using spectroscopy (1H NMR, 13C NMR, MS and FT-IR) and
X-ray crystallography method. The single-crystal structure confirmed by
X-ray diffraction was consistent with the molecular structure optimized
by density functional theory (DFT) calculation at B3LYP/6-311G (2d, p)
level of theory. The geometrical parameters, molecular electrostatic
potential (MEP) and frontier molecular orbital (FMO) analysis were
performed by DFT using the B3LYP/6-311G (2d, p) method. Molecular
docking has shown favorable interaction between the title compound 1 and
SHP2 protein. The inhibitory activity of target compound 1 on SHP2
protein at 10 μM is better than the reference compound (SHP244).

Published: February 2021

Accurate assessment of right ventricular (RV) function is drawing a
growing attention. Pressure-volume (PV) loop analysis is the gold
standard method for evaluating RV function; however, it is not widely
employed due to its invasive nature and complexity. The present report
is the first to have drawn a RV PV loop in a patient with pulmonary
hypertension, with a simultaneous recording of RV pressure and volume
using high fidelity micromanometry and 3D echocardiography. This allows
for less invasive and simple assessment of RV function, potentially
promoting better understanding and management of pulmonary hypertension
and other cardiovascular diseases.

Social entrepreneurship as a tool for the development of non-government organization’s activities: a case study of the association "Oranzais stars"
Authors:   Latvia University of Life Sciences and Technologies, Bale Inga , Auzina Anita ,   Latvia University of Life Sciences and Technologies
Published: February 2021

In Latvia, de-institutionalization is gradually taking place, which is envisaged in the European Social Development Plan at the level of public policy. In Latvia, the non-governmental sector (NGO) sector is largely dependent on external funding. In addition, competition for external financing is increasing. One of the solutions to reduce the effect of external financing is to engage in economic activity. Social entrepreneurship is becoming increasingly popular in Latvia - a business model that allows economic activities to be carried out without losing the mission, goals and social impact of NGOs. Social entrepreneurship is a way of effectively addressing the concerns of different groups at risk of social exclusion, which can have a positive long-term impact on the development of both the city and society itself. Social entrepreneurship has the potential to solve various social problems, thus facilitating municipal work and reducing municipal budget expenditures. For municipalities, social enterprises are a tool for solving social problems, which allows them to solve social problems in the municipalities by using a trans-regional approach, without taking risks on investments, failure, changes in market demand. The aim of the study is to create scenarios for the development of NGO activities, using the example of Association “Oranzais stars” (Orange Ray). Main research methods used: monographic method, strategic analysis and planning methods - PEST, SWOT, VRIO matrix, scenario method. The main result of the methods applied in the thesis is the development of a suitable and sustainable business model as the society moves towards the implementation of social entrepreneurship.

Published: February 2021

In order to ensure the development and competitiveness of an organization, it is essential to continuously enhance processes, particularly those that generate revenue, i.e. business processes, as well as to introduce innovations. One of the business processes at BBS-Dizain Ltd that needs to be enhanced is the catering service. The aim of the research is to examine possibilities for shortening order processing times at BBS-Dizain Ltd. The research concluded that the average rating of order processing time at the restaurant given by the employees of BBS-Dizain Ltd (internal customers) was higher (4 points) than the rating given by visitors (external customers) (3.49 points). A contingency analysis showed that there was no correlation between the ratings given by external and internal customers; therefore, the restaurant’s personnel did not critically assess their performance in terms of order processing time. Since changes in the demand for the dishes on the menu of the restaurant exceeded 25%, and none of the dishes on the menu was a leader in terms of revenue generated, there were no dishes, the cooking process of which BBS-Dizain Ltd needed to optimize. The chefs of BBS-Dizain Ltd could enhance their skills in preparing Group AY meals, as the demand for them was relatively steady. Rearranging the workplace of a chef, using the 5S methodology, and replacing the worktop for the chef with a freezer allows significantly – two-fold – reducing the number of the steps made during the shift. However, rearranging the restaurant’s storeroom, using the 5S methodology, allows saving 95 % time spent on searching for things needed. Therefore, the possibilities to reduce order processing times at the restaurant of BBS-Dizain Ltd involve decreasing unnecessary movements of chefs at their workplaces and reducing the time spent on searching for things in the storeroom.

Pumpkin seed oil (PSO) possesses a protective potential against liver injury due to the presence of biologically active ingredients. Adult male albino rats were administrated PSO (per os, 2 mL/kg b.w./day) and a 12% ethanol solution in water, ad libitum, with an average intake of 8.14 g of ethanol/kg bw/day for 6 weeks. Congestion, hepatic central vein dilation, portal vein branch dilation, Kupffer cell hyperplasia, fatty liver changes, hepatocyte focal necrosis were observed after daily alcohol intake. All observed changes were reduced when PSO was ingested with ethanol. PSO intake itself induced discrete cellular edema, congestion and slight dilatation of the central and portal vain branches. Chronic ethanol intake elevated catalase (CAT) activity and glutathione reductase (GR) protein expression; concomitant PSO intake had no effect on CAT activity or GR protein expression. PSO intake decreased the activities of GR, glutathione-S-transferase (GST) and xanthine oxidase (XOD) in the liver, probably due to the ingestion of antioxidants. Intake of PSO and ethanol significantly decreased cytosolic superoxide dismutase (SOD1) and increased NF-?B protein expression compared to ethanol intake, suggesting that the protective effects of PSO were mediated by the NF-?B signaling pathway. Our results reveal a therapeutic potential of PSO in alcoholic liver disease.
Corporate Social Responsibility and Technological Innovation
Authors: Jia Yonghong , Gao Xinghua , Billings B. Anthony
Published: February 2021

This study examines the relation between corporate social responsibility (CSR) and firm innovation. We replicate and extend the work of Mao and Weathers (2019), who investigate employee treatment and innovation, and find that CSR has an incremental effect on innovation outcomes (measured as citation-weighted patent counts) beyond the documented effect of employee treatment. The CSR effect mostly comes from CSR strengths rather than concerns. This effect remains robust after we address potential endogeneity concerns using three identification strategies. We also find that the CSR effect exists only in situations of more effective board monitoring, stronger CEO leadership, and greater employee human capital, and is greater in complex firms. Our overall evidence is consistent with the argument that CSR enhances technological innovation as it helps firms develop internal resources and capabilities related to creative corporate culture, long-term orientation, and employee knowledge and skills that are critical and conducive to innovation success.

Measuring Accounting Fraud and Irregularities Using Public and Private Enforcement
Authors: Donelson Dain C. , Kartapanis Antonis , McInnis John , Yust Christopher G.
Published: February 2021

Most accounting studies use only public enforcement actions (SEC cases) to measure accounting fraud. However, private cases (securities class actions) also play an important enforcement role. We discuss the legal standards and processes for both public and private enforcement regimes, emphasize the importance of screening cases for credible fraud allegations, and show both yield credible fraud measures. Further, we demonstrate these research design choices affect inferences from prior research and a hypothetical research setting. Finally, we show common measures of accounting irregularities using Audit Analytics to proxy for fraud result in significant false positives and negatives and develop a fraud prediction model for use in future research. We recommend using both public and private enforcement with appropriate screening when examining accounting fraud to reduce Type I and II errors, or reporting the sensitivity of findings across regimes. This is particularly important given the reduction in accounting-related enforcement after 2005.

Corporate Control Contests and the Asymmetric Disclosure of Bad News: Evidence from Peer Firm Disclosure Response to Takeover Threat
Authors: Chen Shuping , Miao Bin , Valentine Kristen
Published: February 2021

We examine the voluntary disclosure behavior of peer firms of hostile takeover targets. We find that peer firms under control threat use a disclosure strategy that emphasizes bad news: they provide more bad news forecasts, tend to bundle bad news forecasts with earnings announcements, use more negative tone in conference call presentations, and more evenly distribute negative tonal words throughout the presentation to heighten the visibility of bad news. This asymmetric disclosure of bad news is concentrated in firms whose managers have greater incentives to mitigate the control threat—firms with younger CEOs, CEOs with higher total compensation, and firms with weaker anti-takeover provisions. Further tests show that peer firms also manage accruals downward. We contribute to the sparse literature on the impact of corporate control contests on voluntary disclosure by demonstrating that peer firms under control threat emphasize bad news to preempt control threat.

Debt Covenants and Accounting Manipulation
Authors: Laux Volker
Published: February 2021

This paper studies the effects of allocating control rights to lenders via debt covenants when managers can sometimes misreport the accounting information on which the covenants are based. When contract renegotiation is exogenously prohibited, including a covenant in the contract is ex ante optimal because it increases both the probability that poor projects are liquidated and the manager's effort incentive. When the parties can renegotiate the contract, the results can flip: granting the lender more control can lead to less frequent liquidations of low-quality projects and lower managerial effort incentives and thereby reduce the manager's ex ante payoff. The key behind these results is not the manager's incentive to misreport per se, but her desire to take subsequent actions that conceal the misreporting. The model generates predictions regarding the determinants of accounting-based covenants, and the effects of covenants on misreporting, managerial effort, the frequency of liquidations, and firm value.

Flat Oral Glucose Tolerance Test During Pregnancy: Maternal Characteristics and Risk for Adverse Outcomes
Authors: Naeh Amir , Wilkof-Segev Renana , Jaffe Anat , Maor-Sagie Esther , Hallak Mordechai , Gabbay-Benziv Rinat
Published: February 2021

Flat oral glucose tolerance test (OGTT) curve is characterized by low glucose levels, seemingly nonresponsive to glucose load. Few studies have explored flat OGTT during pregnancy and have yielded conflicting results, some suggesting risk for fetal growth restriction. This study evaluated the characteristics and perinatal outcomes of women with a flat OGTT during pregnancy. We found that a flat OGTT curve occurs in younger, leaner pregnant women. Also, flat OGTT curve was significantly associated with a male fetus and higher levels of pregnancy-associated plasma protein A at the first-trimester screening. Although flat OGTT can possibly reflect some degree of hyperinsulinemia, it is generally not associated with adverse maternal or neonatal outcomes.

Authors: Kuo Shihchen , Ye Wen , de Groot Mary , Saha Chandan , Shubrook Jay H. , Hornsby W. Guyton , Pillay Yegan , Mather Kieren J. , Herman William H.
Published: February 2021

OBJECTIVE

We estimated the cost-effectiveness of the Program ACTIVE (Adults Coming Together to Increase Vital Exercise) II community-based exercise (EXER), cognitive behavioral therapy (CBT), and EXER+CBT interventions in adults with type 2 diabetes and depression relative to usual care (UC) and each other.

RESEARCH DESIGN AND METHODS

Data were integrated into the Michigan Model for Diabetes to estimate cost and health outcomes over a 10-year simulation time horizon from the health care sector and societal perspectives, discounting costs and benefits at 3% annually. Primary outcome was cost per quality-adjusted life-year (QALY) gained.

RESULTS

From the health care sector perspective, the EXER intervention strategy saved $313 (USD) per patient and produced 0.38 more QALY (cost saving), the CBT intervention strategy cost $596 more and gained 0.29 more QALY ($2,058/QALY), and the EXER+CBT intervention strategy cost $403 more and gained 0.69 more QALY ($585/QALY) compared with UC. Both EXER and EXER+CBT interventions dominated the CBT intervention. Compared with EXER, the EXER+CBT intervention strategy cost $716 more and gained 0.31 more QALY ($2,323/QALY). From the societal perspective, compared with UC, the EXER intervention strategy saved $126 (cost saving), the CBT intervention strategy cost $2,838/QALY, and the EXER+CBT intervention strategy cost $1,167/QALY. Both EXER and EXER+CBT interventions still dominated the CBT intervention. In comparison with EXER, the EXER+CBT intervention strategy cost $3,021/QALY. Results were robust in sensitivity analyses.

CONCLUSIONS

All three Program ACTIVE II interventions represented a good value for money compared with UC. The EXER+CBT intervention was highly cost-effective or cost saving compared with the CBT or EXER interventions.

This article is adapted from a speech Dr. de Groot delivered in June 2020 as President, Health Care & Education, of the American Diabetes Association at the Association’s 80th Scientific Sessions, which was held online as a result of coronavirus disease 2019. Dr. de Groot is an Associate Professor of Medicine in the Division of Endocrinology, Diabetes and Metabolism at Indiana University (IU) School of Medicine. She serves as the Acting Director of the IU Diabetes Translational Research Center. Dr. de Groot is the 2020 recipient of the Rachmiel Levine Medal for Leadership from the American Diabetes Association.

In the year 2020, we marked the 50th anniversary of the field of behavioral science in diabetes in the modern era. Over this relatively short period of time, this field has charted the psychosocial landscape of prediabetes and diabetes by establishing the prevalence and impact of emotional and behavioral aspects of diabetes. Interventions to address these conditions have been developed that span the T2 to T4 translational research spectrum ranging from the intrapsychic to population-based interventions. Policies ranging from standards of care to Medicare benefits have been implemented. A review of research in the area of diabetes and depression is provided as an example of innovations in this field. Behavior is the foundation of all interventions we make in diabetes and prediabetes. As a mature science, it is critical to stemming the tide of diabetes and its outcomes. To make additional strides, we must rebalance our focus and augment funding for behavioral interventions for individuals, communities, and health care systems in conjunction with other forms of treatment.

The Effect of Cast Iron Preheating on the Microstructure of Welding Results by Using Cin-2 Electrodes
Authors: Sabirin Ahmad , Purwantono Purwantono
Published: February 2021

Cast iron is commonly found in engineering tools such as machine frames, vise, lathes, planers, pressing tools, V-belt pulleys and others. Cast iron is a metal which is relatively difficult to weld because it contains more than 0.3% carbon. As a matter of fact, a lot of welding workers still experience failure in welding the cast iron, so they require the proper procedures to perform welding on the cast iron like the heat treatment before the welding. This study was aimed at obtaining the effect of preheating variations on the weld joints in which the process of welding the material used the type of open V seam connection. The specimen used was a cast iron with a thickness of 10 mm and the electrode used was the JIS Z 3252 DFCNiFe electrode. The method applied in this research was the microstructure observation testing toward the welding result by using Shielded Metal Arc Welding (SMAW). Based on the results of the study, it can be concluded that by applying the preheating variation treatment on the cast iron welding, there was a change in the microstructure and it was dominated by pearlite-ferrite in the weld metal area. As a result, the rough graphite that looks like roots became smooth after experiencing the preheating treatment because the ferrite was evenly distributed in the heat affected area. To conclude, the most superior specimen for the cast iron preheating among the four specimens was the one with 425oC temperature.

Published: February 2021

The article examines the information and analytical technology implemented during the operation of electrical networks, based on the capabilities of multi-agent monitoring of the somatic and mental condition of the staff of power grid companies and predictive analysis of anthropogenic risks of energy production within the framework of a risk-based approach to human resource management. The analysis includes instrumental monitoring, assessment of indicators (using objective data) characterizing the condition of operational managers, operational and maintenance staff involved in real technological and business processes for servicing equipment of network companies using optimization theory methods, fuzzy sets, index analysis, provision of integral information to operational managers and management of energy companies, the formation of proposals on the areas of investment in the development of their human resources based on solving the optimization problem of minimizing damage due to wrong actions, inaction and violation of safety requirements for energy production. It is proposed to use a system of dimensionless index indicators for assessing the condition of staff, predictive analysis of the success of their professional activities and the formation of its ontological model in order to manage anthropogenic risks to ensure reliable and safe functioning of energy production with the possibility of developing measures and scenarios of impacts on staff within the production process. The article presents approaches to the formation of monitoring technology, which ensures the construction of unified systems for recording the condition of staff operating electric power facilities, statistics of failures due to staff's fault to determine the optimal type, composition and cost of impact on staff, improving their health based on multi-agent analysis of monitoring data, allowing to direct the flow of events in accordance with the conditions set by the availability of funds for these purposes. The authors have developed a mathematical apparatus, proposed devices and software, with the help of which an automated analysis of the indices of the condition of staff of each category, servicing equipment units (assemblies) and the formation of scenarios of impacts on it (agent-based modeling of condition-controlled behavior) has been carried out.
From a Government-Based Partnership to a Civic-Governed Paradigm

Published: February 2021

This article reports a pioneering qualitative research study that illuminates the way a global philanthropic partnership enabled the Israeli government to launch a national program which later evolved into a non-governmental initiative. It examines the model of an urban and social rehabilitation program through the prism of its funding partnership, citizen participation practice, and collaboration with municipalities; it also illustrates the way this government-based model was transformed into a new program, detached from governmental ties and shifted to focus on communal and international people-to-people connections and collaborations. The article traces the programmatic transformation that unfolded over four decades.
Śmiech - skąd pochodzi, czym jest i czemu służy?
Authors: NETER JULIA
Published: February 2021

Śmiech jako rodzaj ekspresji i komunikacji wyewoluował dużo wcześniej niż mowa, będąc sygnałem współpracy i współdziałania. Pod tym względem spełnia bardziej podstawową funkcję niż uśmiech. Głównym celem niniejszej pracy jest próba udzielenia odpowiedzi na pytania: skąd śmiech pochodzi, czym jest i czemu służy oraz rozwiązania problematyki jego wielofunkcyjności. W ramach podjętej analizy została przeanalizowana współczesna literatura dotycząca tytułowej problematyki i kolejno nakreślona filoi ontogeneza śmiechu u zwierząt oraz ludzi jako zachowania wrodzonego. Następnie przedstawiono jego „produkcję” (także tego, który powstaje podczas łaskotek) oraz ekspresję i indukcję z wątkami patologicznymi. Ostatnia część artykułu traktuje o społecznych funkcjach śmiechu, zwłaszcza jego wpływie na dobrostan funkcjonalny. W zakończeniu opisano dalszy kierunek potrzebnych weryfikacji naukowych a także wyzwań, jakie stoją przed psychologią pozytywną.

W ramach współczesnego kosmopolityzmu można wyróżnić dwa główne nurty stawiające sobie rozbieżne teoretyczne cele. Pierwszy z nich można intepretować jako apologetyczną konceptualizację późnokapitalistycznych tendencji globalizacyjnych, drugi zaś jako próbę przezwyciężenia konfliktów wynikających z oporu wobec globalnej uniformizacji rozmaitości form życia społecznego. Opozycyjność obu tych celów jest odpowiedzialna za istotne rozbieżności we współczesnych doktrynach kosmopolitycznych. W niniejszym artykule, który stanowi próbę ponownego odczytania wybranych momentów w dziejach starożytnego kosmopolityzmu, zwracam uwagę na wewnętrze napięcia tej doktryny, które kształtowały jej rozwój w epoce starożytnej. Moim celem jest wskazanie, w jaki sposób radykalizm moralny i polityczny kosmopolityzmu cynickiego został zastąpiony na gruncie późnego stoicyzmu za pomocą umiarkowanej, gradualistycznej koncepcji Hieroklesa, opartej na idei oikeiosis.
Social containers as a tool of social and spatial segregation

Our paper deals with the establishment of the container settlements in Poland and the grassroots response to it: by the inhabitants and by political activists. In particular we are interested in how local authorities strategically frame housing issues to create social acceptance of diminishing standards of social housing in Poland and the involvement of the mainstream media in the process. We are focusing on strategies as well as tactical efforts to overcome structural and discursive opportunities emerging in the process of the anti- container campaign. Exclusionary discourse about the ‘container ghettos’ becomes a justification for local authorities to use social containers as tool of social and spatial segregation as well as to discipline communal tenants. In response of this process activists had to develop new diagnostic mobilizing frames and put considerable effort into frame alignment processes and forged new alliances with other actors. We analyze the campaign from the perspective of social movement studies, in particular structural theories of collective action. One side effect of such policies is unspoken racism, which we - after E. Balibar - interpret mostly in class terms aimed at the economically maladjusted. Empirically, our paper draws upon sociological intervention and 40 in-depth interviews with the inhabitants of the container settlements in Poland in 7 different cities conducted in 2008-2012; participantobservations of the settlements and of the campaign against them due to personal involvement of one of the authors.

Objetivo: Relatar o processo de criação e confecção de uma sequência pedagógica que foi aplicada com a utilização de jogos didáticos para alunos de ensino médio, da rede pública de educação, em um município do Pará. Relato de experiência: A aplicação da dinâmica aconteceu durante uma Feira de Profissão, no dia 18 de maio de 2019. A feira é um evento organizado por todas as universidades de ensino superior para expor os variados cursos de graduação disponíveis aos alunos do ensino médio. Acadêmicos do curso de enfermagem organizaram o “Tabuleiro Anatômico”, como forma de chamar a atenção dos alunos para uma conhecida disciplina do curso, Anatomia Humana. A partir disso, a dinâmica aconteceu durante os períodos de manhã, tarde e noite, de 08h às 20h, contando com a participação de cerca de 100 alunos de escolas públicas, estes com idades que variavam de 15 a 20 anos. Considerações finais: A estratégia educativa funcionou como um instrumento no ensino de anatomia, trazendo para uma disciplina tida, como exaustiva a ludicidade, um maior interesse no público infanto-juvenil.

Polycystic ovarian syndrome can affect fertility due to anovulatory cycles, luteal phase defects, hyperprolactinemia, and sex hormone imbalance, it remains untreated. The present study aims prevalence of polycystic ovarian disease (PCOD) of clinical/subclinical infertile women, different age groups and to analyze the association between circulatory level of gonadotropins, luteinizing hormone and follicle-stimulating hormone (LH and FSH) and prolactin (PRL) in polycystic ovary syndrome (PCOS) women of different reproductive age and its impact on fertility of women. The hormonal reports for LH, FSH, and PRL of 100 female patients were analyzed. Women suffering from oligomenorrhea and amenorrhea are given priority in this study. These samples were categorized into five different age groups of 15–20 years, 21–25 years, 26–30 years, 31–35 years, and 36–40 years. Obtained hormonal data of LH, FSH, and PRL were pooled and the average was taken to compare with the normal range of hormone. A significant age-dependent variation observed in circulatory serum levels of gonadotropins (LH and FSH) and PRL. The study reveals that the highest PCOD patients were observed in the age group of 21–25 years. Whereas, 30% to 15–20 years, 60% to 21–25 years, 40% to 26–30 years, 30 % to 31–35 years, and 20 % to 36–40 years of reproductive age group. Most affected population of PCOS women ranges in between 21 and 25 age groups, whereas the 36–40 age group was least affected. Age-related alteration in the circulatory level of PRL (hyperprolactinemia) and pulsatility of LH and FSH can be considered as the important factor regulating neuronal mechanisms of hypophyseal gonadal and peripheral endocrine feedback.

Background: Adherence to antiretroviral (ARV) treatment is known as an important component in achieving the success of an optimal HIV therapy program. Poor adherence to antiretroviral therapy (ART) is associated with less effective viral suppression, which creating permanent treatment resistance. The purpose of this study was to examine factors affecting adherence to ARV therapy. Subjects and Method: A cross-sectional study was conducted in Malang, East Java, from September to October 2019. A sample of 200 PLWH was selected by fixed disease sampling. The dependent variable was adherence to ARV therapy. The independent variables were cues to action, perceived susceptibility, perceived benefit, attitude, and CST service. The data were collected by medical record and questionnaire. The data were analyzed by a multiple linear regression. Results: Adherence to ARV therapy in PLWH increased with strong cues to action (OR= 6.40; 95% CI= 3.13 to 13.12; p<0.001), strong perceived susceptibility (OR= 3.61; 95% CI= 1.82 to 7.13; p<0.001), strong perceived benefit (OR= 4.68; 95% CI= 2.37 to 9.28; p<0.001), and positive attitude (OR= 5.39; 95% CI= 2.69 to 10.83; p<0.001). CST service was associated with adherence to ARV therapy but it was statistically non-significant (OR= 0.63; 95% CI= 0.33 to 1.20; p=0.130). Conclusion: Adherence to ARV therapy in PLWH increases with strong cues to action, strong perceived susceptibility, strong perceived benefit, and positive attitude.

Published: February 2021

The article analyses the features of publications of works of art by Ukrainian and foreign writers accompanied by AR applications. The authors substantiate the relevance and outlined the prospects for the use of augmented reality books in reading lessons in primary school. The article demonstrates the possibilities of using AR-technology for the development of creative imagination, emotional intelligence, creative and figurative thinking. A methodical model of augmented reality application at Reading lessons in primary school has been developed. The main stages of this model are detailed: involvement; interaction; listening, reading and listening; research; creative work; evaluation. The main purpose of the proposed model is to involve the “digital generation” in reading activities, the formation of primary school students’ need to learn about the world through fiction. Theauthorshave developedanumber ofgametasks, duringwhichjuniorstudentshave theopportunity to explore the virtual world of the work of art in detail, as well as to interact with literary characters. This approach allows students to visually imagine the reality depicted by the writer, to approach the understanding of images, to learn more about the values, being in the virtual surface of the art world, which contributes to the creative imagination of students and the formation of their figurative thinking. The creative stage involves students expressing their own attitude to what is read. Students are invited to think, compose simple texts about their thoughts, impressions, observations. Besides, on the basis of a work of art, students learn to fantasise: change the ending of the story or invent a new story with the hero of the work of art. The results of reading activities of junior students in the classroom with the use of augmented reality is proposed to evaluate the following criteria: motivational, emotional, active, and valuable. According to these criteria, the indicators are outlined. The results of the study, a survey of primary school teachers and students prove the effectiveness of the use of AR-applications and their benefits for enhancing the reading activities of students.
