Authors: Vogiatzis Antonios , Orfanoudakis Stavros , Chalkiadakis Georgios , Moirogiorgou Konstantia , Zervakis Michalis
Published: December 2022

Multiclass image classification is a complex task that has been thoroughly investigated in the past. Decomposition-based strategies are commonly employed to address it. Typically, these methods divide the original problem into smaller, potentially simpler problems, allowing the application of numerous well-established learning algorithms that may not apply directly to the original task. This work focuses on the efficiency of decomposition-based methods and proposes several improvements to the meta-learning level. In this paper, four methods for optimizing the ensemble phase of multiclass classification are introduced. The first demonstrates that employing a mixture of experts scheme can drastically reduce the number of operations in the training phase by eliminating redundant learning processes in decomposition-based techniques for multiclass problems. The second technique for combining learner-based outcomes relies on Bayes’ theorem. Combining the Bayes rule with arbitrary decompositions reduces training complexity relative to the number of classifiers even further. Two additional methods are also proposed for increasing the final classification accuracy by decomposing the initial task into smaller ones and ensembling the output of the base learners along with that of a multiclass classifier. Finally, the proposed novel meta-learning techniques are evaluated on four distinct datasets of varying classification difficulty. In every case, the proposed methods present a substantial accuracy improvement over existing traditional image classification techniques.
A Novel Discretization Procedure in the CSI-FEM Algorithm for Brain Stroke Microwave Imaging
Authors: Mariano Valeria , Tobon Vasquez Jorge A. , Vipiana Francesca
Published: December 2022

In this work, the contrast source inversion method is combined with a finite element method to solve microwave imaging problems. The paper’s major contribution is the development of a novel contrast source variable discretization that leads to simplify the algorithm implementation and, at the same time, to improve the accuracy of the discretized quantities. Moreover, the imaging problem is recreated in a synthetic environment, where the antennas, and their corresponding coaxial port, are modeled. The implemented algorithm is applied to reconstruct the tissues’ dielectric properties inside the head for brain stroke microwave imaging. The proposed implementation is compared with the standard one to evaluate the impact of the variables’ discretization on the algorithm’s accuracy. Furthermore, the paper shows the obtained performances with the proposed and the standard implementations of the contrast source inversion method in the same realistic 3D scenario. The exploited numerical example shows that the proposed discretization can reach a better focus on the stroke region in comparison with the standard one. However, the variation is within a limited range of permittivity values, which is reflected in similar averages.
A Data-Driven Framework for Small Hydroelectric Plant Prognosis Using Tsfresh and Machine Learning Survival Models
Authors: de Santis Rodrigo Barbosa , Gontijo Tiago Silveira , Costa Marcelo Azevedo
Published: December 2022

Maintenance in small hydroelectric plants (SHPs) is essential for securing the expansion of clean energy sources and supplying the energy estimated to be required for the coming years. Identifying failures in SHPs before they happen is crucial for allowing better management of asset maintenance, lowering operating costs, and enabling the expansion of renewable energy sources. Most fault prognosis models proposed thus far for hydroelectric generating units are based on signal decomposition and regression models. In the specific case of SHPs, there is a high occurrence of data being censored, since the operation is not consistently steady and can be repeatedly interrupted due to transmission problems or scarcity of water resources. To overcome this, we propose a two-step, data-driven framework for SHP prognosis based on time series feature engineering and survival modeling. We compared two different strategies for feature engineering: one using higher-order statistics and the other using the Tsfresh algorithm. We adjusted three machine learning survival models—CoxNet, survival random forests, and gradient boosting survival analysis—for estimating the concordance index of these approaches. The best model presented a significant concordance index of 77.44%. We further investigated and discussed the importance of the monitored sensors and the feature extraction aggregations. The kurtosis and variance were the most relevant aggregations in the higher-order statistics domain, while the fast Fourier transform and continuous wavelet transform were the most frequent transformations when using Tsfresh. The most important sensors were related to the temperature at several points, such as the bearing generator, oil hydraulic unit, and turbine radial bushing.

Published: December 2022

Cities have an undoubted significant role in climate change mitigation. Several cities across the globe have made commitments to sustainability transitions through green strategies. In the recent past, Europe has witnessed a surge in the development of smart cities and advancement towards creating more sustainable cities. At the moment, the concept of Positive Energy Districts (PEDs) further encourages districts and cities to change their business-as-usual ways to be more carbon neutral. This paper looks at the five cities of Maia, Reykjavik, Kifissia, Kladno, and Lviv that are a part of an ongoing Horizon 2020 project. The purpose of the paper was to understand the steps the cities have taken to select the 10 solutions for replication. The information was collected through discussions, interviews and implementation plans developed by each city. It must be highlighted that each city’s circumstances differ in terms of political support, finances, technical expertise, and stakeholders’ interest, and this applies to all world cities when discussing the implementation of new efficient solutions. Cities across Europe and beyond may find themselves in a similar situation, and therefore, this paper also provides a story of the five Fellow Cities as they transition towards PEDs.
How Many Students and Items Are Optimal for Teaching Level Evaluation of College Teachers? Evidence from Generalizability Theory and Lagrange Multiplier
Authors: Li Guangming
Published: December 2022

Budget and cost are two of the problems that cannot be ignored when conducting a measure study. Based on the application of generalizability theory, combined with Lagrange multiplier, this paper explores how many students and items are optimal for teaching level evaluation of college teachers under budget constraints to maintain the sustainable development of higher education. A total of 397 students are required to evaluate 10 teachers’ teaching level using the Teaching Level Evaluation Questionnaire for College Teachers, and we make different generalizability designs (i.e., (s:t) × i, (s:t) × (i:v) and (s:t) × (i:v) × o) for the collected data. The study unifies the Lagrange multiplier formula, derives the optimal sample size formula of different designs under budget constraints in generalizability theory, and calculates the optimal sample size for teaching level evaluation of college teachers in different designs with the estimated variance components. Results indicate that: (1) the unified formula of Lagrange multiplier has a stronger robustness and can be applied to different study designs under budget constraints in generalizability theory; (2) the occasion has a great effect on teaching level evaluation for college teachers; (3) the (s:t) × (i:v) × o design has a high efficiency in estimating the optimal sample size of teaching level evaluation for college teachers; (4) the design of (s:t) × (i:v) × o is the optimal generalizability design of teaching level evaluation for college teachers under budget constraints in generalizability theory; and (5) under budget constraints of teaching level evaluation for college teachers in generalizability theory, the optimal sample size of students is 31 for each teacher and the optimal sample size of items is 7 for each dimension.

Published: December 2022

Shallow landslides restrict local sustainable socioeconomic development and threaten human lives and property in loess tableland. Therefore, the appropriate creation of risk maps is critical for mitigating shallow landslide disasters. The first task to be done was to evaluate the vulnerability of shallow landslides based on a machine learning model (random forest (RF), a support vector machine (SVM) and logistic regression (Log)), and a physical model (SINMAP) in the loess tableland area. By comparing the differences, the best method for evaluating the vulnerability of shallow landslide was selected. The nonlinear response relationship between shallow landslides and environmental factors was quantified based on the frequency ratio. Multicollinearity analysis was used to identify 10 factors that were applied on ML to construct the spatial distribution model. The SINMAP model used a DEM and soil physical parameters to determine the stability coefficient of the study area. The results showed that (1) shallow landslides in Dongzhiyuan mainly occurred on shady slopes with an elevation of 1068–1249 m, a slope gradient of 36°–60° and a concave shape. The stream power and stream transport indexes increased with increasing rainfall erosion, making shallow landslides likely. The susceptibility of shallow landslides changed parabolically with the change in the NDVI and mainly occurred in grassland and shrubland. (2) The four methods performed similarly in predicting the sensitivity of shallow landslides. The high-incidence areas were on both sides of eroded gully slopes. The tableland and gully bottom areas were not prone to shallow landslides. (3) The highest area under the curve (AUC) values were generated from the RF training and validation datasets of 0.92 and 0.93, respectively, followed by SVM AUC values of 0.91 and 0.92, respectively; Log AUC values of 0.91 and 0.89, respectively, and the SINMAP model AUC values of 0.69 and 0.74, respectively. In conclusion, the RF model best predicted the susceptibility of shallow landslides in the study area. The results provide a scientific basis for disaster mitigation on the Loess Plateau.
A New Perspective on Interpreting the Accounting Information of Listed Companies: Research on the Asset Structure Difference and Earnings Value Based on a Sustainable Development Strategic Perspective
Authors: Wu Fengpei , Ock Young-Seok , Su Xiang
Published: December 2022

The quality of accounting information of listed companies has always been of great concern for investors, creditors, government departments, and other stakeholders. As the core component of accounting information, earnings information is essential, which is hailed as a wind vane by every stakeholder. The sustainable development strategy of companies requires companies to reasonably allocate company resources and promote the long-term and rapid development of the company. Based on the sustainable development strategic perspective, this paper takes Chinese A-share non-financial listed companies from 2007 to 2020 as a sample to study the correlation between asset structure differences and earnings value relevance. The research logic of this paper is: the corporate strategy determines the resource allocation scheme of the company, the resource allocation scheme determines the asset structure, and the asset structure determines the generation mode of profits. Therefore, there are different profit compositions, and the differences in profit compositions lead to differences in the corporate earnings value relevance. The research results show that, overall, compared to the companies with a large proportion of investment assets, the companies with a large proportion of operating assets have a stronger earnings value relevance to their net profit. From the perspective of the main composition of profits, companies with a large proportion of operating assets have a stronger value relevance to their core profits. Companies with a large proportion of investment assets have a stronger value relevance to their investment income. Listed companies’ different asset structures is an essential factor affecting the corporate earnings value relevance. Additionally, listed companies’ different asset structure results from the corporate strategic development choice, which shows that the corporate strategy affects the relevance of the corporate earnings value. This provides a new perspective for accounting information users to interpret the corporate earnings information, helps accounting information users to understand and analyze corporate financial statements more accurately, and has a particular reference significance for investment decision making.

Published: December 2022

In this study, we aimed to investigate the presence of an alteration in the feeding ecology of fish after the deployment of anti-trawling reefs at the Punta Tramontana site (Sardinia, Italy). To achieve this aim, we examined prey in the stomach contents of two target species of fish: Diplodus annularis and Mullus surmuletus. The samples were obtained from fishing activities carried out over one year from June 2017 to October 2018 at two impact sites, selected by the presence of artificial reefs, and two control sites. The results showed that installing these artificial devices increased the food spectrum availability of the target species and induced two different ecological feeding behaviors, probably derived from their different ecologies. D. annularis changed its alimentary strategy from generalist at control sites to specialist at impact sites, focusing its diet on the crustacean Gnathia maxillaris. Mullus surmuletus was not affected by the presence of the barriers, which constitute an additional site where the fish feed during their foraging activities. In conclusion, these anti-trawling reefs, in addition to the purpose for which they are designed (in this case, avoiding illegal trawling), did not produce any negative environmental impact on surrounding marine biota.
Chemometrics of the Environment: Hydrochemical Characterization of Groundwater in Lioua Plain (North Africa) Using Time Series and Multivariate Statistical Analysis

Published: December 2022

This study aims to analyze the chemical composition of Lioua’s groundwater in order to determine the geological processes influencing the composition and origin of its chemical elements. Therefore, chemometrics techniques, such as multivariate statistical analysis (MSA) and time series methods (TSM) are used. Indeed, MSA includes a component analysis (PCA) and a cluster analysis (CA), while autocorrelation analysis (AA), supplemented by a simple spectral density analysis (SDA), is used for the TMS. PCA displays three main factors explaining a total variance (TV) of 85.01 %. Factors 1, 2, and 3 are 68.72%, 11.96%, and 8.89 % of TV, respectively. In the CA, total dissolved solids (TDS) and electrical conductivity (EC) controlled three groups. The elements SO42−, K+, and Ca2+ are closely related to TDS, the elements Na+, Cl−, and Mg2+ are closely related to CE, while HCO3− and NO3− indicate the dissociation of other chemical elements. AA shows a linear interrelationship of EC, Mg2+, Na+, K+, Cl−, and SO42−. However, NO3− and HCO3− indicate uncorrelated characteristics with other parameters. For SDA, the correlograms of Mg2+, Na+, K+, Cl−, and SO42− have a similar trend with EC. Nonetheless, pH, Ca2+, HCO3− and NO3− exhibit multiple peaks related to the presence of several distinct cyclic mechanisms. Using these techniques, the authors were able to draw the following conclusion: the geochemical processes impacting the chemical composition are (i) dissolution of evaporated mineral deposits, (ii) water–rock interaction, and (iii) evaporation process. In addition, the groundwater exhibits two bipolar characteristics, one recorded with negative and positive charges on pH and Ca+ and another recorded only with negative charges on HCO3− and NO3−. On the other hand, SO42−, K+, Ca2+, and TDS are the major predominant elements in the groundwater’s chemical composition. Chloride presence mainly increases the electrical conductivity of water. The lithological factor is dominant in the overall mineralization of the Plio Quaternary surface aquifer waters. The origins of HCO3− and NO3− are as follows: HCO3− has a carbonate origin, whereas NO3– has an anthropogenic origin. The salinity was affected by Mg2+, SO42−, Cl−, Na+, K+, and EC. Ca2+, HCO3−, and NO3− result from human activity such as the usage of fertilizers, the carbonate facies outcrops, and domestic sewage.
A State Machine-Based Droop Control Method Aided with Droop Coefficients Tuning through In-Feasible Range Detection for Improved Transient Performance of Microgrids
Authors: Srikanth Mandarapu , Venkata Pavan Kumar Yellapragada
Published: December 2022

The cascaded droop-voltage-current controller plays a key role in the effective operation of microgrids, where the controller performance is critically impacted by the desigheme, a constant value n of the droop controller. Moreover, in critical loading (e.g.: connection/disconnection of large inductive load), the pre-set value of the droop coefficient brings asymmetry in transient performance leading to instability. Hence, to improve symmetry by reducing the trade-off between transient response and stability margin, this paper proposes a state machine-based droop control method (SMDCM) aided with droop coefficients’ tuning through in-feasible range detection. Here, to realize the issues and the role of the droop controller’s dynamics on the microgrid’s stability, a small-signal stability analysis is conducted, thereby, an in-feasible range of droop values is identified. Accordingly, safe values for droop coefficients are implemented using the state machine concept. This proposed SMDCM is compared with the conventional constant droop control method (CDCM) and fuzzy logic-based droop control method (FLDCM) in terms of frequency/power/voltage characteristics subjected to different power factor (PF) loading conditions. From the results, it is seen that CDCM failed in many metrics under moderate and poor PF loadings. FLDCM is satisfactory under moderate PF loading, but, showed 54 Hz/48 Hz as maximum/minimum frequency values during poor PF loading. These violate the standard limit of ±2%, but SMDCM satisfactorily showed 50.02 Hz and 49.8 Hz, respectively. Besides, FLDCM levied an extra burden of 860 W on the system while it is 550 W with SMDCM. System recovery has taken 0.04 s with SMDCM, which completely failed with FLDCM. Similarly, voltage THD with FLDCM is 58.9% while with SMDCM is 3.08%. Peak voltage due to capacitive load switching is 340V with FLDCM and 150 V with SMDCM. These findings confirm that the proposed SMDCM considerably improved the transient performance of microgrids.
Framework for Healthiness Assessment of Water Cycle to Decide the Priority of Enhancement and Restoration Plans
Authors: Jin Youngkyu , Lee Sangho , Kang Taeuk , Kim Yeulwoo , Lee Namjoo
Published: December 2022

The water cycle in watersheds is vulnerable due to climate change; hence, the need for sustainable watershed management is increasing. This paper suggests a framework for a healthiness assessment of the water cycle to provide a guideline for systematic watershed management considering the previous and current states. The suggested framework aims to prioritize restoration and enhancement plans based on the graded healthiness of the water cycle elements by the watersheds. The framework is composed of two assessment procedures: a problem-focused assessment to identify problems such as flood, drought, and river depletion in the watershed and the highest priority assessment to select the watershed for enhancement and restoration plans. The healthiness assessment method for each metric is suggested based on the Korean Framework Act on Water Management. The framework was applied to four different watersheds in South Korea. The framework is proven to be an effective method to identify practical emerging problems for the water cycle in each watershed. The framework can contribute to providing technical information to detect the water problem of the watershed by objectively diagnosing the watersheds with various potential water problems via the healthiness assessment.
Semantic Interpretations of Proper Names in Literary Translation: Terry Pratchett’s “Wyrd Sisters” in Bulgarian
Authors: Manova-Georgieva Yana
Published: December 2022

Name crafting has been and still is of importance when devising a literary character with certain traits and features that are meant to outstand a character’s personality. Thus, literary names serve as a handy tool in any piece of writing, since they complete their bearers in a discrete, yet a vivid way when given an appropriate name by the author of a piece of writing. As far as fantasy is concerned, the choice of literary names is freer, but still requires more creativity, given the fact that fantasy names can be translated. When rendered from one language into another, names undergo various structural alterations, semantic modulations, or even syntactic reconstructions. Therefore, the current paper aims at analysing literary names in Terry Pratchett’s fantasy novel “Wyrd Sisters” with focus on their rendering into Bulgarian. Etymology and semantic interpretations are to be sought for as well as morphological and syntactic structure of names in both languages of interest in favour of the hypothesis that literary names carry meaning which, when revealed, gives a more concrete idea of a personage in a novel.

Published: December 2022

This study aimed to explore the views of pre-service teachers (freshman students) at English Language Teaching program at a state university in Turkey towards the use of L1 (mother tongue) in English as a Foreign Language (EFL) classrooms while also investigating their actual use of L1 during an extracurricular teaching event. It also aims to find out if there is a relationship between participants’ educational background in language learning, their views towards use of L1 and their actual use of L1. This study employed a qualitative approach by collecting data through semi-structured interviews and these interviews were supported with field notes taken by the researcher. The findings showed that ELT students mostly favored the use of L2 (target language) in the classroom and stated that it must be used as much as possible; however, some participants also stated that L1 could be used depending on the proficiency of students. The analysis of the interviews showed that there was no relationship between the participants’ actual use of L1 and their educational background for the participants. Finally, the study suggests some implications towards the ELT curriculum in line with the findings.
Socialización entre mujeres: mandatos de feminidad y propuestas políticas feministas
Authors: Ferreyra Marta Clara
Published: December 2022

En este texto reflexiono sobre tres estrategias de socialización entre mujeres en el marco de la acción política: la lógica de las idénticas (Amorós, 2007), la tiranía de la falta de estructuras (Freeman, 1999) y las tretas del débil (Ludmer, 1984). Señalo la persistencia de mandatos de feminidad en estas estrategias y las analizo alrededor de las propuestas políticas feministas de sororidad y affidamento. Me decanto por esta última pues resignifica las diferencias, liderazgos y autoridades entre mujeres, otorgándoles una valoración positiva y reconociéndolas como estratégicas para la acción política, lo cual, a su vez, siembra terreno fértil para la articulación con otros proyectos de justicia social. Concluyo que transformar las relaciones entre mujeres resulta esencial para fortalecer su incidencia política, especialmente en tiempos donde el retorno de la ultraderecha en diversas latitudes amenaza la fuerza ganada por los feminismos y los derechos de las mujeres en general.

Women’s experiences of heavy menstrual bleeding and medical treatment: a qualitative study in primary care
Authors: Dutton Brittany , Kai Joe
Published: December 2022

Background

Heavy menstrual bleeding (HMB) is common and can affect women’s lives. Evidence on women’s experiences and their treatment of this problem after seeking primary care is lacking.

Aim

To explore women’s experiences of HMB and their medical treatment up to 10 years after initial management in general practice.

Design and setting

This was a qualitative study in UK primary care.

Method

Semistructured interviews with a purposeful sample of 36 women who had participated in the ECLIPSE trial of medical treatments for HMB in primary care (levonorgestrel-releasing intrauterine system or other usual medical treatments — oral tranexamic acid, mefenamic acid, combined oestrogen–progestogen; or progesterone alone). Data were analysed thematically and a process of respondent validation was undertaken.

Results

Women reported the wide-ranging and debilitating impact of HMB on their lives. They had often normalised their experience underlining persisting societal taboos about menstruation and reflecting low general awareness of HMB as treatable. Women commonly delayed seeking help for several years. They could then be frustrated by lack of a medical explanation for HMB. Women who had pathology identified felt able to make better sense of their HMB. Experiences of medical treatments varied considerably but were strongly influenced by the perceived quality of healthcare interactions with clinicians. Other influences on women’s treatment included considerations for their fertility, health concerns, family and peers, and views when approaching menopause.

Conclusion

Clinicians should be aware of the considerable challenges faced by women with HMB; widely differing experiences of, and influences on, their treatment; and the value of patient-centred communication in this context.

Stress, Sleep, and Exercise Habits Among Extension Employees During the COVID-19 Pandemic
Authors: Anding Jenna , Smith Miquela , Cummings Scott
Published: December 2022

We compared perceived stress among 804 Extension employees during the initial months of the COVID-19 pandemic and again six months later. Work expectations, sleep and exercise habits were assessed. More than 46% of those responding believe work expectations are “much” or “moderately more” since the pandemic began. Nearly 60% report moderate levels of stress and 54% were sleeping less. Of those who were physically active (n=677) before the pandemic, 39% were exercising less. Because stress, sleep, and physical activity affect health, supervisors should recognize the impact the pandemic has on employees, and encourage the use of available resources to promote wellness and work/life balance.

Published: December 2022

Misconceptions regarding agricultural careers are exacerbated by increasing urbanization and are one of many differences in perspective between urban and rural communities. The One Georgia 4-H Urban-Rural Experience addresses this divide through a statewide youth exchange focusing on the agricultural sector. The program includes a multifaceted look at agricultural careers through visits to urban and rural communities. Focus group evaluations revealed the impact on youth through exposure to new careers, increased understanding of the diversity of agriculture, awareness of the interconnected nature of urban and rural communities, and a sense of belonging to a diverse group of youth.

The functions of the cabin on agricultural machinery go beyond protecting against the risk of overturning and adverse weather conditions, such as wind and rain. The cabins must also have a shield against physical, chemical, and biological risks, present in crops. In this context, the work aims to present the design of equipment capable of measuring atmospheric pressure, the incidence of ultraviolet radiation from the sun, temperature, and relative humidity of the air, inside and outside agricultural cabins, at the same time. The design methodology used in the development of the equipment demanded the definition of customer requirements, which were converted into design requirements. From the analysis of these, the design specifications were established. To meet the formulated specifications, the functional structure of the equipment was defined through a synthesis process (operating concept). The conception generated by the equipment, in two modules, inside and outside the cabin, allows the performance of differential comparative analyzes between the parameters in the two environments considered, serving as a tool for the development of cabin designs for safer agricultural machines.

Brazil has a diversity of plant species and many of them are medicinal plants used in the production of herbal medicines. Passiflora incarnata is popularly known as passion fruit, its fruits and aerial parts have anxiolytic and sedative properties. Recent studies have shown that P. incarnata has several bioactive compounds such as indole alkaloids, cyanogenic glycosides, maltol and flavonoids. Among the substances identified in the species, vitexin has action on the Central Nervous System, interfering with the functioning of gamma-aminobutyric acid. Thus, the objective of the study was to identify and quantify the vitexin present in the ethyl acetate fraction of the aerial parts of the passion fruit. For this, the aerial parts of P. incarnata were submitted to extraction with ethanol, followed by fractionation in organic solvents, obtaining the hexane, dichloromethane and ethyl acetate fractions. The presence of vitexin in the ethyl acetate fraction was verified by Thin Layer Chromatography (TLC) and the total flavonoid content by colorimetric reaction in a spectrophotometer. The quantification of vitexin was performed by High Performance Liquid Chromatography (HPLC). The total flavonoid content was 5.34 mg/g and 960 µg/g of vitexin in the ethyl acetate fraction. Studies like this contribute to the development of new pharmaceutical formulations from the substance vitexin.

A Diretriz Nacional para Elaboração do Programa de Gerenciamento do Uso de Antimicrobiano em Serviços de Saúde, desenvolvida pela ANVISA em 2017, reza que a elaboração de protocolos para esses programas deve ser realizada de maneira multidisciplinar, sendo que este pilar é o que mais demonstra desafios. Para além destes, há também desafios voltados aos dados coletados e recursos financeiros. A partir do alto consumo de antibióticos, os programas de gerenciamento são capazes de causar impacto clínico, econômico, além do bem-estar do paciente. Diante dos impactos das diretrizes, o objetivo desta revisão sistemática é descrever o papel dos programas de gerenciamento para antibioticoterapia em unidades hospitalares e os principais desafios no seu desenvolvimento e implementação. Foi realizado um levantamento de dados nas bases PubMed, Periódico Capes e Lilacs, utilizando como critérios de elegibilidade a leitura dos títulos, resumos e conteúdo geral de acordo com o que fora selecionado. Durante o desenvolvimento desta revisão foram utilizados descritores que levaram a busca por artigos que relacionavam a implementação de programas de gerenciamento de antibióticos em hospitais onde são descritos desafios encontrados nesta ação. Fora realizada a leitura dos 819 artigos selecionados e logo após a aplicação dos critérios de elegibilidade restaram 11 onde foi feita leitura integral e foram extraídos 48 desafios principais onde o mais recorrente está relacionado à equipe multidisciplinar. Durante este estudo uma das maiores dificuldades foi encontrar artigos que relatassem a respeito das dificuldades, pois a maior parte destes demonstraram somente a execução e o êxito na implementação. Após a análise dos desafios encontrados, evidenciou que 37,5% deles são relacionados à equipe, com destaque na resistência dos profissionais envolvidos, além de outros como a ausência de dados confiáveis (8,3%), falta de recursos tecnológicos/financeiros (8,3%) e falta de capacitação (12,5%), que podem impactar diretamente na implementação destes programas.

Дана робота присвячена дослідженню тимчасових змін типів земногопокриву в межах природно-заповідного фонду України. Перш за все, цеаналіз зміни лісового покриву (вирубка чи лісовідновлення) за відкритимиданими Global Forest Change 2000–2020 з просторовою роздільноюздатністю 30 м з визначенням найбільш проблемних типів заповідників, девідбувалась вирубка лісів у 2000–2020 рр. Іншим аспектом дослідженняє моніторинг використання земель природно-заповідного фонду длясільського господарства, зміни площ сільськогосподарських полів у часі таїх порівняння. Це дослідження проведено на основі власних карт земногопокриву з просторовою роздільною здатністю 10 м за 2016–2020 рр., а такожу порівнянні з відкритим набором даних World Cover Map для Україниза 2020 р. Для створення власних карт земного покриву для всієї Українивикористані оптичні супутникові (Sentinel–2) та радарні дані (Sentinel–1).У роботі описана технологія побудови карт класифікації земного покривудля великих територій на основі супутникових даних. Розглянуто основніетапи попередньої обробки супутникових даних, методологія злиттяданих різної та однорідної природи за різні часові дати. За допомогоюнаборів геопросторових продуктів досліджено динаміку змін площі лісу тапосівних угідь за різними видами природно-заповідного фонду України за2000–2020 рр. Найбільшу частку ліси займають в заповідних урочищах,парках-пам’ятках садово-паркового мистецтва та дендрологічних парках(більше 73 % лісів), з яких найбільші зміни відбулися в заповідних урочищах на 1,81 % площ (1,7 тис. га) та дендрологічних парках — на 1,02 %площ (17 га). Дослідження та результати показали, що в цілому на національному рівні зміни з часом не суттєві (до 3 % для лісів і до 2 % длясільськогосподарських площ), однак вони мають велике значення,оскільки природні ресурси обмежені, а якість життя людства залежитьнасамперед від природи, екології та якості навколишнього середовища.
