Institutional Approaches for Studying System-Oriented Networks
Authors: Taylor Cody , Nowell Branda
Published: May 2024

Institutional, policy, and management scholars and practitioners are increasingly interested in leveraging network perspectives, methods, and data to understand complex social phenomena, including the various stages of the policy process, community mobilization, and coupled natural and human systems. Viewing these phenomena through the lens of system-oriented networks can be valuable for understanding and intervening within complex policy arenas. However, currently, there is no clear consensus on who and what constitutes a relevant actor in a system-oriented network. Furthermore, numerous conceptual and methodological traditions for conceptualizing, measuring, and analyzing system-oriented networks have arisen, and each is linked to different disciplinary traditions. In this paper, we showcase six approaches from the public policy and public management literature for conceptualizing and analyzing system-oriented networks. We offer a conceptual framework for characterizing different approaches which considers differences in their focal system of interest, analytical focus, theoretical orientation, and approach for determining network boundaries. We review these elements with an eye toward helping scholars and practitioners interested in system-oriented networks to make informed decisions about the array of available approaches.

Radio-frequency identification technology finds extensive use in various industrial applications, including those involving metallic surfaces. The integration of radio-frequency identification systems with metal surfaces, such as those found in the automotive sector, presents distinct challenges that can notably affect system efficacy due to metal’s tendency to reflect electromagnetic waves, thus degrading the functionality of conventional radio-frequency identification tags. This highlights the importance of conducting research into academic publications and patents to grasp the current advancements and challenges in this field, aiming to improve the applications of radio-frequency identification tags technology on metal. Consequently, this research undertakes a concise review of both the literature and patents exploring radio-frequency identification technology’s use for on-metal tags, utilizing resources like Google Scholar and Google Patents. The research categorized crucial aspects such as tag flexibility, operating frequency, and geographic origins of the research. Findings highlight China’s prominent role in contributing to metal-focused radio-frequency identification tag research, with a considerable volume of articles and patents. In particular, flexible tags and the Ultra-High Frequency range are dominant in both scholarly and patent documents, reflecting their significance in radio-frequency identification technology applications. The research underscores a vibrant area of development within radio-frequency identification technology, with continued innovation driven by specific industrial needs. Despite the noted advances, the presence of a significant percentage of no longer valid patents suggests substantial opportunities for further research and innovation in radio-frequency identification technology for on-metal applications, especially considering the demand for flexible tags and for solutions in systems that offer specialized characteristics or are tailored for specific uses.

Background: In Nigeria, most children with tuberculosis (TB) present at primary health clinics where there are limited personnel skilled in collecting appropriate respiratory specimens from those who cannot produce sputum. KNCV Nigeria, in collaboration with the National Tuberculosis Control Program, implemented a modified simple, one-step (SOS), stool-based Xpert MTB/RIF method for diagnosis of TB in children who cannot expectorate sputum. We evaluated the impact of its implementation on childhood TB diagnosis. Method: A cross-sectional study was conducted across 14 selected states using secondary data of children presumed to have TB. Stool was collected from children presumed to have TB and processed using Xpert. Result: Out of 52,117 presumptive TB cases, 52% were male and 59.7% were under 5 years old. A total of 2440 (5%) cases were diagnosed with TB, and 2307 (95%) were placed on treatment. Annual TB notifications increased significantly after the introduction of the stool-based Xpert test when compared to those in the pre-implementation period. Increasing contributions from stool testing were observed throughout the implementation period, except in 2020 during the COVID-19 era. Overall, stool Xpert testing improved childhood TB notification in the studied states. Interventions aimed at awareness creation, capacity building, and active case finding improved the performance of the test.

Authors: Adeyanju Gbadebo Collins , Essoh Tene-Alima , Sidibe Annick Raissa , Kyesi Furaha , Aina Muyi
Published: May 2024

Background: Cervical cancer, caused by human papillomavirus (HPV) infection, is the second-largest cancer killer of women in low- and middle-income countries. The brunt of the global burden is borne predominantly in Sub-Saharan Africa. In 2020 alone, 70,000 of the 100,000 infected women in Africa died from it, thereby making up 21% of global cervical cancer mortality. The introduction of the HPV vaccine into the National Immunization Program was expected to change the trajectory. However, uptake of the vaccination has been poor, especially for the second dose. Only about half of the countries in Africa currently provide the vaccine. Without urgent intervention, the 2030 global cervical cancer elimination targets will be undermined. The study aims to understand the key challenges facing the HPV vaccine and to develop a roadmap to accelerate the uptake. Method: Fourteen countries were purposively included using a cohort design methodology and the investigation spanned March–July 2023. The Africa region was stratified into three focus-group discussion cohorts (Abidjan, Nairobi and Dar es Salaam), comprising pre-selected countries that have already and those about to introduce the HPV vaccine. In each country, the EPI manager, the NITAG chair or representatives and an HPV-focal researcher were selected participants. The methods involved a collaborative and knowledge-sharing format through regional and country-specific discussions, plenary discussions, and workshop-style group missions. Results: The study reached a total of 78 key stakeholders, comprising 30 participants in cohort one, 21 in cohort two and 27 in cohort three. Key outcomes included the prevalence of declining HPV2 vaccination across all countries in the region; country-specific barriers impeding uptake were identified and strategy for accelerating vaccination demand initiated, e.g., utilizing investments from COVID-19 (e.g., electronic registry and multisector coordination); individual countries developing their respective HPV vaccination recovery and acceleration roadmaps; the identification and inclusion of a zero-dose catch-up strategy into the vaccination roadmaps; support for a transition from multiple-doses to a single-dose HPV vaccine; the incorporation of implementation science research to support the decision-making process such as vaccine choices, doses and understanding behavior. Conclusion: Beyond research, the study shows the significance of scientific approaches that are not limited to understanding problems, but are also solution-oriented, e.g., development of roadmaps to overcome barriers against HPV vaccination uptake.

Published: May 2024

Dams are regarded as crucial pieces of structure that store water for irrigation and municipal uses. Given their vital role, the dam’s water quality assessment is considered to be an important criterion and requires constant monitoring. In this research, we attempted to use two water quality indices (WQIs) methods to assess the water quality of the Keddara Dam, which is located on the Boudouaou River, Algeria, using eleven water quality parameters (temperature, pH, conductivity, turbidity, total suspended solids (TSS), full alkalimetric title (TAC), hydrometric title (TH), nitrite ions (NO2−), nitrate ions (NO3−), ammonium ions (NH4+), and phosphate ions (PO43−)) for data recorded from 29 December 2018 to 3 June 2021. Application of The Canadian Council of Ministers of the Environment (CCME) WQIs and the Weighted Arithmetic Method (WAM) indicated that the Keddara Dam’s water quality parameters were within the WHO’s permissible level, except for the conductivity and turbidity values. The results of the CCME WQI ranged from acceptable (81.92) to excellent (95.08) quality, whereas the WAM WQI ranged from 9.52 to 17.77, indicating excellent quality. This demonstrates that the Keddara Dam is appropriate for agriculture and municipal use. The water quality indices (WQIs) methods are recommended as valuable tools that allow both the public and decision-makers to comprehend and manage the water quality of any aquatic environment by providing flexibility in choosing variables.

Published: May 2024

Key Points

The revised ANCA kidney risk score accurately predicts ESKD in patients with ANCA-associated vasculitis, with increasing risk associated with higher scores.

ANCA kidney risk score performs well in this population, identifying new risk factors and showing similar effectiveness to the previous ANCA renal risk score.

Background

Predicting the outcome of ANCA-associated vasculitis is a difficult task. One of the most promising prognostic scores, the ANCA renal risk score, has recently been updated and renamed to ANCA kidney risk score (AKRiS). We wanted to test its performance in our population.

Methods

In total, 164 patients were included and categorized in subgroups analogous to that of both scores. Multivariable logistic regression analysis was applied to assess the risk of renal failure. In addition, baseline data and outcome were compared between the subgroups of each score to retrieve useful clinical information.

Results

Stratified by AKRiS category, the proportions of patients who developed ESKD at 36 months were 9.8%, 29.1%, 63.0%, and 83.3%, respectively (P < 0.001). Those belonging to the higher risk groups showed more pronounced proteinuria and anemia at diagnosis (P = 0.001, P < 0.001, respectively). Although our patients exhibited a more severe disease phenotype than those of ANCA renal risk score and AKRiS, both scores performed equally well: The Harrell C-index was similar (0.8381 versus 0.8337). Beyond that, we found differences and similarities in the risk associations between the subgroups of both scores and disease activity or patient outcome, with some of them being described for the first time. For example, there was a higher risk of renal failure with anemia but not with C-reactive protein and the Birmingham Vasculitis Activity Score and an increased incidence of relapsing disease in the lower risk categories of ANCA renal risk score.

Conclusions

Here, we present the first external AKRiS validation confirming the improved ESKD prediction of the revised score in our cohort. Furthermore, we highlighted associations between risk score categories and patient mortality or vasculitis relapse.

Published: May 2024

Background: Infective endocarditis (IE), a severe and economically impactful condition, lacks substantial epidemiological data in the North Africa and Middle East (NAME) region. This study focused on analyzing the trends and burden of IE in NAME from 1990 to 2019, taking into account factors like age, gender, and socio-demographic index (SDI). Methods: The Global Burden of Disease data from 1990 to 2019 was retrieved from the Institute for Health Metrics and Evaluation (IHME) website. Results: Between 1990 and 2019, the age-standardized rates (ASR) for IE incidence increased by 59%, and prevalence and years lived with disability (YLDs) rose by 12% and 9%, respectively, while the ASRs for deaths, disability-adjusted life years (DALYs), and years of life lost (YLLs) saw reductions of 22%, 34%, and 34% in the NAME region. Death rates among children under five declined by 72%. Gender and the SDI did not significantly influence these changes. Saudi Arabia witnessed the most significant increase in ASR of IE incidence since 1990, while Turkey had the highest rates in 2019. The year 2019 also saw the highest death rate among those aged 70 and over, with over 91000 DALYs from IE. DALYs decreased by 71.5% for children under five from 1990 to 2019 but remained stable for individuals in their seventies. Jordan showed the most notable decrease in ASRs for deaths, DALYs, and YLLs among children under five. Conclusion: This study highlights the changing epidemiology of IE in the NAME region, recommending the establishment of multidisciplinary IE registries, antibiotic prophylaxis guidelines for healthcare-associated IE, and strategies to control antimicrobial resistance as key mitigation measures.

Authors: Momayaz Sanat Zahra , Siami Zeinab , Alatab Sudabeh , Vahedi Homayoon , Fanni Zeinab
Published: May 2024

Human cytomegalovirus (HCMV) is classified within the Herpesvirales order and is prevalent in 50%‒80% of the general population. Most carriers experience this infection without noticeable clinical symptoms. HCMV causes a lifelong latent infection that can be reactivated due to immune disorders and inflammation. The reactivation of HCMV becomes particularly significant when it coincides with inflammatory bowel disease (IBD). While cytomegalovirus (CMV) colitis in IBD patients was identified years ago, the role of CMV in triggering flare-ups, acute severe colitis, treatment resistance, and other outcomes in IBD patients experiencing CMV reactivation remains a subject of ongoing debate. In this review, we aim to address an updated insight into aspects related to the CMV colitis in IBD patients including epidemiology, risk factors, clinical features, diagnostic tests, histology, place of immunosuppressants and indications for antiviral treatment. We suggest for personalized and thorough assessment based on the disease phase and colitis severity when prescribing drugs to these patients. Furthermore, we emphasize the importance of regular patient follow-up to monitor drug side effects, ensuring treatment success, and minimizing the risk of colectomy.
Numerical simulation of the influence of detonation products on a supersonic airflow process
Authors: S.S. Vasiliv , K.V. Ternova
Published: May 2024

Currently, there is a large number of control bodies used in modern rocket technol-ogy. Gasdynamic systems are usually used in rocket engines to change the thrust vector, less often - to create asymmetric air flow around the case. But the application of the det-onation process for such scheme can have better energy and dynamic characteristics compared to existing systems. The driving force in such scheme is created not only by the reactive mass force of detonation products ejected from the gas generator, but also by the effect of an intense shock wave on the pattern of supersonic flow around the rocket. Therefore, it is necessary to evaluate the performance and efficiency of the experiment. The purpose of the study is a priori numerical study of the detonation wave effect on the supersonic flow in the nozzle. Modeling was carried out in the Solid Works application software package. The geometric parameters of the model coincide with the experimental model. It is a flat nozzle, one of the walls is longer than the other and imitates the surface of the rocket. Air, accelerating in the nozzle to supersonic speeds with Mach number M=1.3...2, flows around this wall. Setting devices affecting the flow in it, it is possible to investigate their influence and the possibility of creating a lateral (controlling) force. When detonation is used to disturb the flow, an intense shock wave is generated in it, which changes the pres-sure distribution on the wall surface. Some holes for pressure sensors are made in the wall to fix this disturbance over time. A priori numerical modeling was carried out in order to estimate the parameters of the interaction of detonation products with the supersonic air flow. The pressure range and duration of the process have been determined, which allows selection of equipment and planning of the experiment. Patterns of velocity and pressure distribution in the model over time were obtained.

Authors: M.O. Lukianets , Y.S. Sulema
Published: May 2024

Recent advancements in Internet of Things (IoT) technologies have led to an exponential increase in the generation of temporal multimodal streaming data from various IoT devices. Aggregating and processing this data efficiently poses significant challenges, including scalability, reliability, and synchronization issues. This paper proposes a novel method for aggregating temporal multimodal streaming data from IoT devices based on reactive programming principles. We begin by analyzing recent research and publications in the field to identify existing challenges and limitations in aggregating temporal data from IoT devices. The key problem addressed in this study is the efficient aggregation of data streams while ensuring scalability, reliability, and synchronization across different devices. The primary objective of this research is to develop a method that can hierarchically organize and aggregate temporal data streams from IoT devices while addressing the challenges of scalability and reliability. To achieve this, we leverage reactive programming techniques, specifically the GroupJoin operation, which allows for the seamless integration of data streams from multiple sources. Our method involves initializing the aggregation process by passing relevant data streams from two devices to the GroupJoin operation and configuring the settings for operation. Additionally, we introduce flexibility in the aggregation process by allowing for the hierarchical structuring of data streams based on physical or logical criteria. Furthermore, we discuss the implementation of our proposed method using the Rx library for .NET, which provides implementations for various programming languages, ensuring its adaptability across different platforms. We benchmark the performance of our method against a naive implementation, demonstrating its efficiency and scalability in aggregating temporal data streams from IoT devices. In conclusion, our proposed method offers a scalable and reliable solution for aggregating temporal multimodal streaming data from IoT devices. By leveraging reactive programming principles, we address key challenges in data aggregation and provide a flexible method for organizing and processing data streams efficiently.

Authors: Ako Ignatius , Olowu Owin
Published: May 2024

To obtain a thorough understanding of the influence of schistosomiasis infections on the transmission dynamics of tuberculosis, a deterministic mathematical model for the transmission dynamics of tuberculosis (TB) co-infection with schistosomiasis is created and examined. The aim of the research is to examine the reasons behind the backward bifurcation in the co-infection dynamics of tuberculosis and schistosomiasis. The backward bifurcation phenomena can be caused by the following parameters, according to the model's analysis (when the associated reproduction number is less than one), other than the well established route of exogeneous re-infection of latently infected TB individuals, the relative rates at which humans with latent schistosomiasis ($\eta_1$) and active schistosomiasis ($\eta_2$) are infected with TB, respectively, the lowered rate of reinfection with schistosomiasis ($\psi$), the fraction of individuals who experience fast progression to active TB ($p$), the adjustment parameter which accounts for the increased probability of infectiousness of humans with active TB and latent schistosomiasis ($\Pi_1$), the treatment rate of people infected with active TB exposed to schistosomiasis ($\zeta_{T1}$) and the rate of progression to active TB and exposed to schistosomiasis to active TB and active schistosomiasis ($\sigma$).
EU regulations on reporting sustainable development as a determinant of limiting the environmental pressure of chemical enterprises in Poland
Authors: Kryk Barbara , Kożuch Małgorzata
Published: May 2024

The period of validity of Directive 2014/95/EU, which imposed on enterprises the obligation to present non-financial information in separate non-financial reports, the so-called ESG was aimed to check its effects, complementary regulations and actual actions in the environmental area. Numerous works have analysed various aspects of non-financial reporting in the context of the directive, including several on ESG reporting in relation to air pollution emissions. However, it has not been examined yet whether there is a relationship between the level of reporting and the effects of pro-environmental activities in the context of the impact of regulations on it. A research gap in this area was identified, and therefore, the aim of the paper is to examine how selected chemical companies in Poland adapt to the EU guidelines on ESG reporting in the environmental dimension and whether it has an impact on reducing their pressure on the environment. The research period is 2010-2022, and the three-stage study used a quantitative-qualitative methodological approach. In the first and third stages, descriptive statistics and time series analysis methods were used. The second one includes methods such as content analysis, case analysis, GES Risk Rating, and expert analysis. The research carried out made it possible to conclude on the impact of non-financial reporting regulations on the environmental pressure.

Authors: ФРОЛОВА Л. А. , БАСКЕВИЧ О. С.
Published: May 2024

В останні роки область використання феритів кобальту розширюється. Перш за все це обумовлюється його специфічними властивостями, такими як високі значення коерцитивної сили, хімічна стабільність, значна магнітокристалічна анізотропія. Фізико-хімічні властивості нанодисперсних феритів кобальту залежать від багатьох факторів (технологія отримання, умови синтезу, природа вихідних речовин). Наразі актуальним є розробка і використання новітніх технологій синтезу феритів, що забезпечують отримання нанодисперсного продукту. Крім того, на властивості фериту кобальту впливає наявність додаткових катіонів металів. Змішані ферити дуже перспективні у зв'язку з можливістю варіювання їх властивостей. У роботі розглядалася можливість використання методу планування експерименту щодо вибору оптимальних режимів феритизації при синтезі кобальт-нікелевого фериту. Фазовий склад феритів визначали рентгенофазовим аналізом. Магнітні властивості визначалися за допомогою вібраційного магнітометру. Залишкову намагніченість, коерцитивну силу визначали за побудованими петлями гістерезису. На основі численних експериментів, були обрані як основні технологічні параметри, що впливають на магнітні характеристики, вихідне рН розчину, час обробки, температура проведення процесу. У роботі розглянуто вплив умов синтезу на залишкову намагніченість, коерцитивну силу та константу анізотропії нікель-кобальтових феритів, отриманих плазмовим методом. Для побудови експериментально-статистичних моделей було використано повний трифакторний експеримент. Встановлено, що основними впливовими факторами є початкове рН розчину, температура обробки. Представлені математичні моделі адекватно описують отримані залежності. Результати показали, що рН реакційної середовища є параметром, який збільшує значення залишкової намагніченості, коерцитивної сили та константи анізотропії.

Косметичні емульсійні креми увійшли у повсякденні потреби життя кожної родини. Через прагнення мати зволожену шовковисту шкіру і відтягнути момент появи зморшок попит на креми зростає з кожним роком. Відбувається стрімке удосконалення технологій, складників, різноманітність інгредієнтів стає все більш широкою. Емульсійні креми – це однорідна суміш двох основних фаз: водної та жирової типу вода – олія, олія – вода або змішаного типу, до складу яких можуть бути внесені біологічно активні добавки (вітаміни, настої та екстракти рослинної сировини тощо). Враховуючи анатомічні та фізіологічні особливості шкіри на різних ділянках, що визначають необхідність інтенсивного косметичного впливу і, відповідно, вимоги до складу, дерматологічні, косметичні, споживчі характеристики кремів, створення кремів на основі емульсії потребує використання цілого комплексу допоміжних речовин, які забезпечують стабільність крему. Допоміжні речовини проявляють біологічну активність, що дозволяє їм включатись у деякі біохімічні процеси структур шкіри, підсилюючи косметичну ефективність діючих інгредієнтів. В той же час їх вплив не завжди є безпечним для здоров’я та шкіри споживача, тому дослідження складників косметичних засобів є надважливим завданням. Проведено дослідження складових емульсійних косметичних кремів для обличчя різних торгових марок: «Lancôme Hydra Zen Anti-Stress Moisturizing Cream», «Biotherm Aquasource Gel», «La Roche-Posay Effaclar Duo (+) Acne Treatment Cream». Визначено основні активні інгредієнти та проаналізовано їх вплив на властивості косметичних засобів. Показано, що досліджені креми не містять в своєму складі компонентів, які здатні негативно впливати на стан шкіри. Встановлено, що за органолептичними показниками досліджувані зразки повністю відповідають нормативній документації. Експертним методом проведена бальна оцінка емульсійних косметичних кремів для обличчя. Визначено, що крем «Lancôme Hydra Zen Anti-Stress Moisturizing Cream» за органолептичними показниками отримав максимальну кількість балів, але більш ефективним за своєю дією виявився емульсійний крем «La Roche-Posay Effaclar Duo (+) Acne Treatment Cream».

Published: May 2024

У роботі розглянуто питання формування цінової задоволеності пацієнтів медичних закладів як конкурентної переваги, що дозволяє приваблювати та утримувати пацієнтів в умовах конкуренції, що постійної зростає. На основі використання методу «контент-аналізу» показано основні підходи до визначення категорії «задоволеність» споживача, що в свою чергу дозолило розвинути зміст терміну та обґрунтувати її складові для сфери послуг. Так, в сфері послуг задоволеність споживача містить як раціональні, так і емоційні складові. Крім того, з огляду на характер та характеристики послуг, споживач приймає рішення щодо їх покупки орієнтуючись на ціни, оскільки через них може судити про якість послуг та сформувати уявлення про цінність що буде надана споживачеві. Дано роз’яснення щодо ролі ціни у формуванні задоволеності споживача, яку можна охарактеризувати як вирішальну. Показано, що цінова задоволеність споживача є складовою унікальної цінності, яка, в свою чергу, становить необхідну умову забезпечення конкурентоспроможності медичного закладу на ринку медичних послуг. Встановлено, що цінова задоволеність споживача вимірюється такими якісними характеристиками як прозорість, гідність, сприятливість, безпека, надійність та чесність та дано характеристику кожної з зазначених складових. Розглянуто три основні фази виникнення цінової задоволеності споживача медичної послуги: формування очікування, порівняння, цінова задоволеність, дано їх характеристику, з’ясовано основні чинники, що впливають на формування цінової задоволеності. Як результат виділено три основні види цінової задоволеності, що можуть мати різні наслідки, найгіршим з яких може бути повна відмова від послуг підприємства. Виділено складнощі з якими можуть зіштовхнутися постачальники послуг на різних фазах виникнення цінової задоволеності, які потребують опрацювання з метою їх уникнення та підвищення ефективності задоволення споживачів. Надано практичні рекомендації щодо формування цінової задоволеності пацієнтів медичних закладів, з урахуванням наявних сучасних технологій та каналів комунікації зі споживачем. Водночас подальшої деталізації потребують інструменти формування цінової задоволеності, які дозволять сформувати ефективну маркетингову стратегію медичного закладу.

Методичну основу даної наукової роботи складають висновки щодо аналізу і теоретичного узагальнення наукових підходів до координації економічного розвитку в умовах цифрової циркулярної економіки, що наведені в роботах теоретичного та практичного характеру. Для досягнення поставленої мети в статті використані методи графічної інтерпретації результатів аналізу та узагальнення, методи теоретичного аналізу, синтезу. У статті встановлено, що останнім часом світова економіка функціонувала в лінійному форматі. Автори дійшли висновку, що такий тип економічного розвитку створює певні ризики для нормального існування всього світу, який споживає більше ресурсів, ніж може відновити. Доведено, що циркулярна економіка це змінює. Визначено, що для реалізації таких світоглядних рішень у глобальному вимірі важливо створити відповідну цифрову основу. Встановлено, що впровадження цифрових технологій належить до засобів забезпечення переходу до замкнутої економіки. Зроблено висновок, що нові технології та бізнес-моделі, а також високі темпи їх впровадження несуть нові ризики (втрата даних, неякісне програмне забезпечення, технічне відставання, недостатній рівень компетенцій, порушення конфіденційності втрата робочих місць, технічні збої), але кібербезпека робить швидкі цифрові зміни безпечнішими. Зазначається, що для мінімізації цих ризиків важливо впроваджувати ефективні заходи кібербезпеки, регулярно оновлювати системи та програмне забезпечення, налагоджувати навчання персоналу та дотримуватись етичних стандартів використання технологій. Зрештою, брак впевненості користувачів у безпеці онлайн-сервісів та захисті конфіденційності ставить під загрозу можливість використання повного потенціалу інформаційно-комунікаційних технологій для стимулювання інновацій, циркулярного економічного зростання та прогресу в напрямку таких трансформаційних змін. Встановлено, що з розвитком цифровізації та комп’ютеризації як у виробничих процесах, так і в повсякденному житті масштаби кіберзагроз будуть зростати пропорційно збільшенню набору циркулярних продуктів і послуг, що використовують інформаційні технології, та кількості їх споживачів. Зважаючи на це, забезпечення кібербезпеки є актуальним завданням державного та приватного секторів, а розробка адекватних заходів протидії таким викликам і загрозам стає важливим вектором державної політики. Доведено, що проблема кібербезпеки стає надзвичайно гострою та важливою, з цього випливає, що подальший розвиток циркулярної економіки в умовах цифровізації та отримання її переваг людством нерозривно пов’язане з одночасним розвитком відповідної системи кібербезпеки.

Authors: Tkachenko Alla , Pozhuev Oleksandr
Published: May 2024

In the study, the place of virtual assets in property and obligation relations and the possibility of their recovery in the event of declaring the debtor bankrupt were considered. Investigating the legal status of virtual assets, existing contradictions were established regarding: the form of existence of virtual assets; recognizing them as a means of payment on the territory of Ukraine or as an object of exchange for property (goods), work (services); determination of virtual assets that may be levied upon enforcement of decisions by bodies of the state executive service, etc. It is noted that the procedure for recovering virtual assets is partially determined by the Civil Code of Ukraine. It is emphasized that none of the articles of the GCU provides for the regulation of either the circulation of virtual assets or the mechanism of their recovery in the event of declaring a business entity bankrupt. KUzPB also ignored virtual assets. In civil law, virtual assets are recognized as an object of law and are subject to recovery in case of forced execution of decisions by state executive bodies, in economic law, as objects of law, they are completely ignored. It is substantiated that in order to ensure the timely, complete and impartial execution of court decisions and decisions of other bodies (officials), the provisions of the Law of Ukraine "On Virtual Assets" dated February 17, 2022 under No. 2074-ХХ need to be brought into compliance with the Law of Ukraine. About executive proceedings" dated June 2, 2016 according to No. 1404-VІІІ in the part of defining a clear and completed mechanism for foreclosure on virtual assets in a compulsory manner. A Roadmap has been proposed to ensure the possibility of recovery of virtual assets in the event of declaring the debtor bankrupt, the implementation of which will contribute to the creation of the legal field necessary for the settlement of transactions with virtual assets.

This research attempts to investigate the teacher talk types employed in classroom interaction using Flander Interaction Analysis Categories System (FIACS) framework. This research was qualitative research with a descriptive method. The research participants were an English teacher and eleventh-grader students of SMAN 1 Gunungsari. The data collection method is audio recording and observation. The data were collected through two class meetings. To analyze the data, the researchers used interaction analysis systems adapted from Flanders (1970). The study’s findings showed that the seven types of teacher talk were found in classroom interaction with varied percentages of certain occurrences. Of the seven types, lecturing and giving directions were mostly applied by the teacher, which indicated that the teacher’s domination in classroom interaction was high. The teacher offered the students more information and knowledge as well as gave them directions, commands, or orders in the learning process. It also showed that the percentage of direct talk was higher than indirect talk. It is expected that the teachers would use this study as a reference to think about the types of teacher talk they should use to raise their students' engagement in classroom interaction.

Sickle cell disease still constitutes a worrying public health problem today. In its major form, it remains a significant cause of infant mortality in our countries. Objective: To study the epidemiological aspects of sickle cell disease in the pediatric department of Sikasso hospital. Methodology: This is a prospective cross-sectional study running from January 1, 2017 to December 31, 2017, a period of one year, meeting the inclusion criteria. Results: During the study period, 4800 patients were consulted in the department including 72 cases of sickle cell anemia, i.e. a prevalence of 1.5%. The average age was 29.5 months. Children under 5 years old were the most represented with 55.5% of cases. The male sex was more common with a sex ratio of 1.4. Depending on the father's Hb type, the AS form represented 87% of cases. In 14 cases, or 70%, the mothers of our patients carried the sickle cell AS trait. Patients were known to have sickle cell disease before the age of 5 in 55.5% of cases. The SS form was the most represented with 57% of cases. The circumstances of discovery were dominated by abdominal pain and osteoarticular pain with 41.7% and 27.8% respectively. Pallor and jaundice were the most common signs on admission with 37.5% and 17.5% of cases respectively. Complications were dominated by CVO and infection with respectively 56.2% and 25%. Conclusion: Difficulties remain in management, linked on the one hand to the unfavorable socio-economic conditions of our populations and on the other hand to the unavailability of certain key tests such as hemoglobin electrophoresis and reticulocyte levels at Sikasso hospital.

A strong business intelligence strategy can deliver accurate data and reporting capabilities faster to business operators; help them make better quicker business decisions. Holding this statement constant, the researchers investigated business intelligence and decision making in MSMEs in Africa. The study is qualitatively done with six participants who responded to an unstructured questionnaire employed to gather the needed relevant data. The collected data were meticulously transcribed and analyzed. After completion, the numerous data entry forms underwent internal validation to guarantee that the replies were accurately categorized before being harmonized and divided into two main categories- competitive advantage and operational efficiency. The Study found that business intelligence is pivotal for timely decision-making in firms especially in the MSMEs sector of the Nigeria economy as it is a strategy used by owner-managers in the organization to achieve operational efficiency and competitive advantage in a tense business environment like Nigeria. It is evident, therefore, that Africa especially Nigeria is not doing badly in the MSMEs sector of the economy and to sustain this stride, governments at all levels must factor in MSMEs and technology into their policy formulation and implications. It is only when that is done that Africa in general and Nigeria, in particular, can boost of not only registering its name in the global economic map but will have a viable economic base that will continue to attract foreign direct investment.

Authors: Mbugua James Kariuki
Published: May 2024

This study set out to investigate the effect of operational risk management on the performance of commercial real estate entrepreneurial investments in Kenya. The study adopted a descriptive survey design having a quantitative approach. The target population was 9,320 real estate entrepreneurs comprising 884 sourced from SoftKenya directory, 95 from the Kenya Developers Association, 320 from the Estate Agent Registration Board and 8,021 from National Construction Authority having their registered offices in Nairobi, Nakuru, Kisumu and Eldoret. A sample size of 384 participants was selected using a stratified random sampling procedure. Data was collected using an online questionnaire emailed to respondents. The collected data was analysed descriptively and inferentially using frequency distribution – mean and standard deviation, Chi-square, Pearson’s Correlation and multiple linear regression analysis with the aid of the Statistical Package for Social Sciences (SPSS), version 20.0. The significance of each risk factor was examined using Risk Significant Index method. From the study findings, operational risks were found to be relatively low in severity compared to technical, financial and environmental risks in the commercial real estate sector in Kenya. The level of management effort in mitigating sources of operational risk was also low. Management of operational risk coefficient attained a statistical significance, which leads to the conclusion that operational risk management affects the performance of commercial real estate entrepreneurial investments in Kenya. With more than 60% of the staff in the sector having low knowledge of risk management, bridging the skill and knowledge gap is critical for better risk management outcomes for the sector. This responsibility should be shared between the government and the real estate entrepreneurs. The government should create forums or curriculum where risk management practice and concepts are trained.

Authors: Makino Shinji
Published: May 2024

Valsalva retinopathy is as the rupture of superficial capillaries secondary to an increase in retinal venous pressure, following a sudden change in intrathoracic or intra-abdominal pressure. The Valsalva maneuver is quite common in daily life and typical activities such as coughing hard, vomiting, straining, constipation, and sexual activity can all lead to it. We reported a rare case of multi-level hemorrhages by the Valsalva maneuver in an elderly female with hypertension after heavy straining due to constipation.
