SMART PUBLIC OPINION MONITORING AND ANALYSIS SYSTEM FOR ETHNIC REGIONS: A MULTI-MODAL APPROACH USING MACHINE LEARNING
Authors: Li Yuexuan , He Junlin , Xiang Wei
Published: March 2024

In ethnic regions, public opinion plays a vital role in shaping social stability and harmony. However, monitoring and analyzing public opinion in these regions can be challenging due to the complex linguistic and cultural factors involved. To address this issue, this study proposes a Smart Public Opinion Monitoring and Analysis System for Ethnic Regions, which utilizes a multi-modal approach for data acquisition and machine learning techniques for analysis. The system collects public opinion data from multiple modalities, including text, speech, image, and video, and uses intelligent speech processing and text translation to analyze non-textual data. The sentiment analysis module evaluates the polarity of public opinion, while the topic modeling module identifies key topics and keywords of public interest. The system also includes an early warning and risk detection module that uses machine learning algorithms to detect potential risks and generate alerts in real-time. Finally, the data visualization module presents the analysis results in an intuitive and user-friendly manner. The proposed system has been tested on a dataset of public opinion data from ethnic regions, and the results demonstrate its effectiveness in monitoring and analyzing public opinion in different modalities. The system can help government agencies and relevant stakeholders to respond quickly to potential risks and maintain social stability in ethnic regions.
Public Administration in the Conditions of War: Challenges and Prospects
Authors: Kryvoruchko Iryna
Published: March 2024

The article analyzes modern approaches to the concept of public administration, outlines a number of features of this concept, and defines modern challenges and key problems of public administration in the conditions of war in Ukraine.
It has been established that the process of formation of the domestic system of public administration should begin with the creation of an appropriate institutional environment aimed at the formation of new value orientations for the entire society and each person separately. Particular attention is paid to guaranteeing the social well-being of society, solving urgent problems of a social and economic nature, ensuring and improving the quality of life of the population, especially in conditions of war.
It is substantiated that the policy of public administration should include the implementation of the following stages: monitoring and analysis of the effectiveness of the functioning of the economy in the conditions of modern globalization processes and uncertainty under conditions of war; development and justification of the goal and key tasks of the socio-economic development of the state; the formation of an effective and efficient mechanism of the public administration system.
In order to build an effective system of public administration for Ukraine, it is proposed to solve the following tasks: redistribution of powers between public authorities, as well as elimination of duplicate functions between them; expansion of opportunities for the participation of representatives of civil society in the process of public administration; increasing the level of motivation of civil servants; improving the quality of administrative services; further digitization of the public administration system; coordination of the activities of economic entities with the aim of ensuring comprehensive socio-economic development of both individual territories and the country as a whole.
Implementation of the State Policy for the Development of the Health Care System in the Conditions of European Integration on the Basis of Risk Management Strategy
Authors: Zamchiy Serhii
Published: March 2024

The article examines the essence and peculiarities of strategic management of the development of the health care system in conditions of uncertainty and the main directions of implementation of the European integration state policy of the development of the health care system based on the risk management strategy and the assumption that the transformational processes accompanying the functioning and development of health care I encourage radical, not partial changes in the relevant system.
It was found that the formation of a system of multi-level management of the functioning and development of the health care system based on risk management should cover all its subsystems and components, as well as provide for the division into several successive stages, or stages, each of which represents real changes in system during a certain period of time, taking into account the risks inherent in each level of its functioning, taking into account the interaction of various subjects, whose activities are aimed at achieving certain socially significant results.
It was determined that the goal of risk management in the health care system should be considered to be the formation of a certain set of targeted measures and actions, the reduction of the actual deviation from the achievement of planned goals and objectives and the corresponding performance indicators due to the selection of a risky alternative and the minimization of losses from the risk, as well as on the basis of: using means of avoiding and reducing the degree of risk in a legal way; control and optimization of risk when it is not possible to avoid it in full; conscious acceptance of the degree of risk in the case when this decision is justified from a socio-economic, political, technological and managerial position.
It is proven that under conditions of uncertainty, there is a need to build an effective risk management strategy and apply appropriate management mechanisms in the process of implementing the state policy of health care development and its integration into the European public and social space. The risk management strategy for the implementation of the state policy for the development of the health care system should be understood as a certain set of targeted measures, as well as a set of methods and means of risk identification, their forecasting and response in order to control and reduce the probability of making unreasonable decisions, the results of which may lead to negative consequences for the functioning and development of the relevant system with further analysis of the results of relevant decisions.

aim: Ruptured abdominal aortic aneurysm (rAAA) is associated with a high mortality rate which, is especially significant in rural and provincial regions. In Aotearoa New Zealand, Māori experience higher rates of AAA and worse overall medium-term survival following AAA repair. This study aimed to understand the prevalence of incidental AAA on routine abdominal computed tomography (CT) scans over 12 months. method: A retrospective review of all abdominal CT scans performed on patients ≥50 years at Gisborne Hospital between 1 December 2018–1 December 2019 was performed. results: A total of 811 scans were reviewed, with 42 incidental AAA detected (5.2%). The majority of incidental AAA were in males aged ≥65 (65.8%), with a higher prevalence for Māori compared to New Zealand European (NZE) (16.2% vs 8.1%, p=0.052). This pattern was also seen in females, aged ≥65 (10.9% in Māori vs 3.8% in NZE, p=0.047). conclusion: The detection of AAA on routine abdominal CT scans appears to be a useful adjunct in lieu of targeted AAA screening in our region. A high prevalence of incidental AAA (5.2%) over 12 months, with a significantly higher prevalence noted in Māori males and females ≥65 years (16.2% and 10.9%), was observed.

Medical simulation has become an integral aspect of modern healthcare education and practice. It has evolved to become an essential aspect of teaching core concepts and skills, common and rare presentations, algorithms and protocols, communication, interpersonal and teamworking skills and testing new equipment and systems. Simulation-based learning (SBL) is useful for the novice to the senior clinician. Healthcare is a complex adaptive system built from very large numbers of mutually interacting subunits (e.g., different professions, departments, equipment). These subunits generate multiple repeated interactions that have the potential to result in rich, collective behaviour that feeds back into the organisation. There is a unique opportunity in New Zealand with the formation of Te Whatu Ora – Health New Zealand and Te Aka Whai Ora – Māori Health Authority and the reorganisation of the healthcare system. This viewpoint is a white paper for the integration of SBL into our healthcare system. We describe our concerns in the current system and list our current capabilities. The way SBL could be implemented in pre- and post-registration phases of practice are explored as well as the integration of communication and culture. Interprofessional education has been shown to improve outcomes and is best done with an interprofessional simulation curriculum. We describe ways that simulation is currently used in our system and describe other uses such as quality improvement, safety and systems engineering and integration. The aim of this viewpoint is to alert Te Whatu Ora and Te Aka Whai Ora of the existing infrastructure of the simulation community in New Zealand and encourage them to invest in its future.

Published: March 2024

Gadung tuber (Dioscorea hispida dennst.) is a carbohydrate-rich food source that is easily
found in Indonesia. Studies have been carried out on pretreatment methods to reduce antinutritional compounds in gadung tubers. So gadung tubers can be promoted as the raw
materials of several food products such as pasta. Drying is the most crucial process that
will determine the final quality of the pasta product. This study aimed to investigate the
kinetic models of gadung tuber pasta drying and its physical quality. Four thin-layer
models (Newton, Page, Handerson-Pabis and Logarithmic) were employed to find the
selected model. The gadung tuber pasta was formulated using low, medium, and high
protein wheat flour and then was dried at a temperature of 30-70℃. The moisture content
was observed every 30 mins for 240 mins. The result showed that the moisture reduction
was higher in higher drying temperatures and lower protein wheat flour. The Logarithmic
model was selected to predict the drying kinetics of gadung tuber pasta drying with the
highest value of R2
and the lowest value of RMSD. The cyanide content in gadung tuber
pasta meets the standard, indicating that the gadung tubers pasta may safety to consume.

Published: March 2024

Encapsulation is one of the methods to protect iron from oxidation. Among the
encapsulation methods, gelation could be the simplest one. This method requires the
matrix which could form a gel. Alginate fulfills the requirements as an encapsulant by
creating beads. However, performances of the encapsulation are determined by the
conditions of the gelation process. The aim of this study was to study the effect of the iron
-alginate ratios (0.05-0.5, w/w) and pHs of gelation (5-10) on the properties of alginate
beads for iron encapsulation. CaCl2 solution was used as a cross-linked agent to form
beads. Solution of iron-alginate was dropped into CaCl2 solution (150 mL, 1 M) using 5-
mL unneedled syringe from about 5 cm above the cross-linked solution surfaces. The
results showed that the ratio of iron-alginate and pH have a negative correlation with
moisture content, diameter beads, and encapsulation efficiency but iron loading. Neutral
pH-gelation produced softer bead texture. The highest efficiency encapsulation was found
in pH 5 of gelation. Release of iron was higher in pH 6.8 than that in pH 1.2. Increase in
iron-alginate ratio led to have more syneresis effect. However, higher pH-gelation tended
to have lower syneresis.

META-NARRATIVE OF SANSKRIT IN INDIAN ENGLISH WRITINGS
Authors: Dr. Shreeja Tripathi Sharma
Published: March 2024

Sanskrit has been the primary language and the receptacle of sublime expressions in early India. The language became an object of engagement for Indologists and Orientalists who began a series of translations of Sanskrit works in English and initiated an association that subsequently culminated in form of Indian English Writings. The gradual absorption of English in Indian culture became partly accountable for rendering original works of Sanskrit inaccessible due to incomprehensibility as well as distortions in translations and cultural misrepresentations. Yet, it was also the chief reason why crucial works of the Sanskrit tradition survived. It is in this context that this research paper analyses Sanskrit as an enduring source of influence in the genesis of the canonical tradition of Indian Writings in English.

A Semantic-Sensitive Approach to Indoor and Outdoor 3D Data Organization
Authors: Wei Youchen
Published: March 2024

Building model data organization is often programmed to solve a specific problem, resulting in the inability to organize indoor and outdoor 3D scenes in an integrated manner. In this paper, existing building spatial data models are studied, and the characteristics of building information modeling standards (IFC), city geographic modeling language (CityGML), indoor modeling language (IndoorGML), and other models are compared and analyzed. CityGML and IndoorGML models face challenges in satisfying diverse application scenarios and requirements due to limitations in their expression capabilities. It is proposed to combine the semantic information of the model objects to effectively partition and organize the indoor and outdoor spatial 3D model data and to construct the indoor and outdoor data organization mechanism of “chunk-layer-subobject-entrances-area-detail object.” This method is verified by proposing a 3D data organization method for indoor and outdoor space and constructing a 3D visualization system based on it.

Authors:   Financial University,  Moscow, Russia, Ruban-Lazareva N.V.
Published: March 2024

The subject of the study is tax risks arising in the implementation of strategic tasks of Russia's development to ensure the achievement of socially significant results in the breakthrough scientific, technological and socio—economic de-velopment of the country, improving people's living standards in 2024. The objectives of the work are to identify the essence and sources of significant tax risks that create uncertainty in the implementation of strategic objectives of Russia and national projects, and the formation of their consequenc-es/probabilities matrix. The sources of tax risks visualized using the Ishikawa method are analyzed. The key problems preventing the successful fulfillment of the strategic tasks set for the Russian economy and the implementation of na-tional projects are shown. The essence of tax risks is established as a result of the influence of tax uncertainties on the fulfillment of the tasks of national pro-jects and the ways to prevent them as a result of the control and analytical work of tax authorities aimed at ensuring macroeconomic stability and a steady increase in socio-economic indicators are presented. Proposals have been formulated to eliminate the sources of tax risks. The con-clusion is made about the need for continuous tax control of tax risks during the entire period of fulfillment of the national development goals of Russia.

Authors:   Financial University,  Moscow, Russia, Popova A.V.
Published: March 2024

The subject of the study is public relations related to ensuring state policy in the social sphere and strengthening the foundations of the welfare state in Russia. The purpose of the work is to develop theoretical ideas about the doctrine of the welfare state and its practical implementation in the legislation of the Russian Federation. Due to the analysis of theoretical approaches to the definition of the concept of "social state" from a legal point of view, it has been established that at present there is an urgent need to clarify the substantive content of the concept of a social state. Through a comparative legal analysis of federal and regional legislation in the social sphere, the need for the adoption of a social code has been identified, which should be valid throughout the state due to the fact that a huge array of normative legal acts, legal documents related to the socio-economic sphere of life of Russian society, not only complicates the work of state bodies designed to ensure the implementation of the doctrine of social the state, but also the realization of human and civil rights and freedoms on the territory of Russia. It is concluded that the social doctrine of the Russian Federation should proceed from the spirit and letter of the Constitution of the Russian Federation, the principles of social justice and social equality based on the understanding of the welfare state, assuming mutual responsibility of citizens, society and the state.
Problems and Prospects of Tax Policy for the Sustainable Development of Regions
Authors:   Financial University,  Moscow, Russia, Panskov V.G.
Published: March 2024

The subjects of the research are the policy of the federal center in relation to the regions and its impact on ensuring sustainable development and economic growth in Russia. The purpose of the work is to identify the reasons for the insufficient effectiveness of regional tax policy, in the development and justification of measures that contribute to solving existing problems in ensuring sustainable economic development. The essence of two terminologically similar concepts is analyzed: "regional tax policy" and "regional tax policy" – and it is proved that they have a fundamentally meaningful difference. The substantiations are given, indicating that the current regional tax policy does not fully contribute to increasing economic activity, strengthening the responsibility of regional and municipal authorities, ensuring the sustainable development of the relevant territories and generates dependency. It has been established that the achievement of sustainable development of the territory can be ensured on condition of increasing the level of independence of regional and local budgets and increasing the share of their own, and primarily tax, revenues. It is proved that a shift in emphasis is required from financial assistance to regions and municipalities towards increasing the share of their own tax revenues, as well as decentralizing the tax powers of government authorities by giving regions and municipalities their rights to tax administration and management of elements of federal taxes received by the relevant budgets. Conclusions are drawn that further improvement of regional tax policy should be carried out by practical solutions to the problem of increasing the budgetary independence of regional and local authorities, increasing the efficiency of their activities, responsibility and interest in the sustainable development of the economy of the territories and accelerating the pace of development of the Russian economy as a whole.

Authors: Siddiqui Raqshan Wajih , Siddiqui Tabish Wajih , Siddiqui Shiza Wajih
Published: March 2024

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects the overall cognitive, emotional, social, and physical health of the affected individual. It is characterised by challenges in social communication and interaction, repetitive and stereotyped behaviours, and narrow interests. The pathogenesis of ASD is thought to involve a combination of genetic and environmental factors. Increasing evidence suggests that vitamin D deficiency during pregnancy and early childhood may contribute to the development of ASD. While studies have indicated that vitamin D supplementation can significantly improve symptoms of ASD, the underlying mechanism remains elusive. This review summarises the association between vitamin D levels and ASD, explores potential mechanisms underlying vitamin D's role in ASD, and examines the effect of vitamin D supplementation on ASD symptoms.

Land fires in South Sumatra are an annual problem during the long dry season. It was recorded that in 2015, 2016, 2017, and 2018, the land fires spread massively in the four districts of South Sumatra. The peatlands located within oil palm plantations in the Districts of Ogan Komering Ilir, Banyuasin, Musi Banyuasin, and the district of Ogan Ilir were the source of the fire. The haze not only attracts national but also international attention. Besides human contribution to land fire, climate change should also be considered. The role of El Nino makes the season uncertain. Land fires affect human health and other human activities in the affected areas. Three legal instruments guarantee and protect the people's right to the environment, i.e., The 1945 Indonesian Constitution, the 2009 Law No. 32 on the Environment, and the 1999 Law No. 39 on Human Rights. The problem raised herein is to what extent people can claim the right to a clean environment as human rights guaranteed and protected in those legal instruments. The results of the discussion show that those three legal instruments do not protect people whose human rights have been violated. This is because 2000 Law No. 26 on Human Rights has no jurisdiction over environmental matters. It is suggested that establishing a special Environmental Court is the solution to protect community environmental human rights cases.

Published: March 2024

The illicit cigarette trade has begun to receive scholarly attention globally. Empirical studies on the illicit cigarette trade are available in the context of Indonesia. However, the Indonesian judicial system lacks a focus on treating illegal practices. To fill the gap, we examine Indonesian court decisions involving the illicit cigarette trade between 2010 and 2019. We provide an overview of the enforcement of Indonesia’s Excise Law 2007 relating to offences related to the illicit cigarette trade. By using a systematic quantitative literature review, we collected data on Indonesian court decisions and found the following: (1) convictions for the practice of illicit trade in cigarettes were relatively steady, with a total number from one to six court decisions annually; (2) certain offences from Indonesia Excise Law 2007 have not been found in the convictions, suggesting their underutilisation in terms of monitoring and enforcement effort; (3) the primary motivation of illicit cigarette traders as reported through the judicial system is the economic benefit or “profit” available to the enterprise; and (4) the sentencing decisions are dominated by the application of the “cumulative principle” with fines and imprisonment applied at the same time. The finding on the average length of imprisonment for illicit cigarettes, which was around 18 months, shows that this crime has low risk compared with the punishment for illicit trade in drugs and narcotics in Indonesia.

The main purpose of this article was to study the behavior of vehicle transmission belts in conditions similar to real ones, which can appear during their use. Transmission belts can be classified into several categories, but depending on their function, can be belts that work in dry conditions or immersed in oil. In this study, were analyzed both types of transmission belts. The samples were subject to different physical-mechanical tests: determination of hardness, density, thickness, abrasion, flex resistance, tensile strength and percentage extension and also to various conditions like, high and low temperature, immersion in liquids (oil, toluene, diesel). All the tests were performed before and after exposure, according to actual standards in ICPI accredited laboratory. Microscopy studies were done before and after the exposure to various factors, in order to appreciate the damage degree. Also, chemical specific analyses were made for determining the transmission belts composition. The findings from this study provide important insights into the behavior of transmission belts under different operating conditions.
Evolution of migration processes in Cladocera populations
Authors: Razlutskij V. I.
Published: March 2024

An intrinsic rate of population increase (r) in a local habitat is determined by the birth-to-death ratio and by migration processes. In natural populations, including Cladocera, r is estimated as the logarithm difference of population densities at the end and at the beginning of time interval. Under this method of evaluation, migration processes are already included in the final population density. A realized intrinsic rate of population increase (rmax) can be determined from the data on age-related mortality and fecundity by the life table method. The high regression relation (R2 = 0.867) was found between rmax, the first time of reproduction (Drepr) and mean fecundity during the reproduction period (mean_mx). Drepr is known for most of Cladocera, the mean_mx analog can be easily determined in their natural populations; these parameters can be used to evaluate a possible intrinsic rate of population increase (rcalc). The differences between r and rcalc can be used to evaluate migration processes. If these differences are positive, then individuals are emigrating from the population, if they are negative, then there occurs the influx of immigrants.

Published: March 2024

The results of using poly(methyl methacrylate) coatings for the development of the capacitive sensors for analyzing the content of heavy metals in water (using Ni2+ ions as example) are presented. Structural and morphological characteristics of the formed conductive nickel layer and nanostructured poly(methyl methacrylate) films were studied by atomic force microscopy. Based on the analysis of the dependence of the capacitive characteristics of the original sensor on the frequency at different concentrations of Ni2+ ions, the following operating characteristics of the sensor were established: response time – 5 min; operating range of Ni2+ ion concentrations: 1 ‧ 10–3–50 mM; lower detection limit ≈ 0,06 mg/l. It is shown that the formation of a poly(methyl methacrylate) coating on a conductive nickel layer by the spin coating method increases the service life of the sensor to eight cycles while maintaining the level of sensor sensitivity.
Analysis of Potential Cropping Seasons of Cayenne Pepper (Capsicum frustescens L.) Based on Water Balance in Alfisol Dryland, Tuban Regency, East Java, Indonesia
Authors: Zuhdi AH. Maftuh Hafidh , Indarwati Lisa Dwifani
Published: March 2024

Dryland agriculture is crucial for understanding how to effectively manage land water for the crops. Water balance analysis plays a pivotal role in comprehending the hydrological cycle and water availability for crop production. The Tuban Regency is one of the fifth largest cayenne pepper-producing areas in East Java, Indonesia, particularly in Grabagan and Bancar Districts. However, for sustainable growth, it is imperative to extend cultivation to other sub-districts within Tuban Regency. In the cultivation of cayenne pepper, attention to soil water availability is important due to its susceptibility to drought, directly impacting vegetative growth and overall plant production. This research aims to establish a planting pattern for cayenne pepper based on water balance analysis in Alfisol drylands within Montong, Kerek, and Singgahan Districts of Tuban Regency. The study, conducted from July to September 2023, employed Thornthwaite and Mather water balance analysis,drought index assessment, and day without rain analysis. The research findings reveal variations inwater balance conditions within the study areas, with Montong and Kerek Districts experiencing a land water surplus for three months and a nine-month deficit. Singgahan District, on the other hand, encountered a surplus for four months and a deficit for eight months. The drought index indicates a high level, peaking in September for Montong (87%), Kerek (91%), and Singgahan (87%) Districts. Cayenne pepper plants exhibit the potential for annual cultivation in Alfisol drylands of Montong, Kerek, and Singgahan Districts, with a growing duration of six months. The optimal planting window spans from December to May, followed by potentially a second planting in June and July for crops with a minimum available water value exceeding 19% or those with a shorter harvest life. From August to November, the land lies fallow due to a soil water availability that is close to 0% and a 27% risk of days without rain in the extreme drought category, rendering the soil unsuitable for growing crops.

Published: March 2024

Grain quality is essential for assessing the overall quality of the grain produced and determining the market value of the final product. The objective of this study was to evaluate the physical quality of grains cultivated using both organic and non-organic methods. The research employed grains from red, white, and black rice genotypes planted during the third period. Each sample consisted of 100 grams, with three replicates. Data analysis involved variance testing using T and BNT tests, with a significance level set at 5%. Parameters for assessing the physical quality of grains included moisture content, empty grains, damaged kernels (yellow), calcified kernels (young kernels), foreign matter, other varieties, odors, and pests. The research took place at the Polytechnic Organic Farm and Plant Laboratory of Politeknik Negeri Lampung from January to April 2022. The findings indicated that the grain yields of red, white, and black rice genotypes quantitatively exhibited lower levels of yellow/damaged kernels and calcified/young kernels when cultivated organically compared to non-organic methods. However, for other analyses, the results did not show significant differences between the two cropping systems. Nevertheless, the grains of red, white, and black rice genotypes met the quality standards outlined in SNI 01-0224-1987, classified as grade II for organic cultivation and grade III for non-organic cultivation.
Performance of Convergent Breeding Wheat (Triticum aestivum L.) Lines in the Lowlands

The development of tropical wheat in Indonesia is currently confined to the availability of wheat’s optimal environments in the highlands. Wheat competes with major highland crops, such as vegetables, which also have high economic values. Despite this, the demand for wheat in Indonesia remains high, whether in the form of wheat flour, wheat meal, or oats. Wheat breeders are actively working to create various crossbreeds so that wheat can adapt and perform effectively in lowland areas. The convergent breeding method is one of the strategies employed to produce genotypes with superior performance. Convergent breeding enhances genetic diversity by incorporating superior traits from all parent plants. The breeding results expedite the emergence of genetic combinations between selected parents. This method involves combining several parent varieties with various traits, with the hope that their offspring will inherit all the characteristics of the crossed parents. Our study with wheat convergent breeding has reached the F6 generation, and in this current study we evaluated the performance of each observed trait in different environments, with the goal of determining the levels of homogeneity and homozygosity. The study utilized a randomized complete block design with three replications, and the crops were planted in various locations. The planting locations selected were those that are >1000 m above sea level (asl), and at a lowland of ± 250 m asl. Wheat performance based on stomatal characteristics showed a reduction in the lowland, which indicates a response to climatic conditions in a particular environment. The higher the environmental temperatures, the smaller the stomatal size, which reduces plant water loss. Noteworthy findings include the tallest plant in CBF-6. CAMN23(265), the highest number of tillers in CBF-6. CAMN233 and CBF-6.CAMN8(4), the largest flag leaf area in CBF-7.CAMN60, and the highest 100-seed weight, as well as overall yield in CBF-7.CAMN119. An analysis of the lowland sensitivity index identified ten moderate genotypes that could potentially adapt well and achieve optimal yields.

Memória Musical na Doença de Alzheimer: Uma revisão sistemática
Authors:   , Mendes Maiky Jhones do Amaral
Published: March 2024

Objetivo: Avaliar a preservação da memória musical explícita, implícita e autobiográfica em indivíduos com Doença de Alzheimer.

Método: Trata-se de uma revisão sistemática da literatura, onde foram analisados os primeiros 100 resultados da plataforma Google Scholar com os descritores music+memory+alzheimer, e após 3 processos de inclusão foram selecionados 9 artigos, sendo 4 envolvendo a memória explícita e implícita e 5 envolvendo especificamente a memória autobiográfica. Foi avaliada a preservação da memória em um total de 153 indivíduos com DA, 243 idosos saudáveis e 86 jovens saudáveis, totalizando 329 indivíduos do grupo controle e um total de 482 indivíduos testados.

Resultados: Foi evidenciada uma perda severa da memória episódica em indivíduos com DA, ao passo que a memória semântica foi preservada tanto no estágio leve e moderado, e até em alguns casos graves da demência. A memória implícita (de habilidades) foi preservada em diversos indivíduos com DA, pois mantiveram suas habilidades musicais com pouca ou nenhuma perda. Além disso, a exposição a um estímulo musical familiar pode auxiliar na evocação de memórias autobiográficas em indivíduos com demência, mas os resultados não se diferenciam nos grupos controle, mostrando que apenas os indivíduos com DA desfrutam deste efeito.

Conclusões: Este estudo evidenciou que a música exerce grande influência na memória do indivíduo, sendo parte dela preservada até mesmo em uma demência severa como a DA. Sendo evidenciadas essas preservações, mais estudos que abordem tais domínios da memória podem ser realizados em âmbito nacional para analisar possíveis alterações demográficas. Além disso, mais estudos podem ser feitos em relação a utilização destes aspectos na melhora da qualidade de vida dessas pessoas, visto que a música pode agir nas consequências severas da demência, e pode ajudar tanto o indivíduo com DA, quanto seus familiares.

PROTEGIENDO A LAS MUJERES POLÍTICAS DE LA VIOLENCIA 2023
Authors: Santano Ana Claudia
Published: March 2024

El proyecto "Protegiendo a las mujeres políticas de la violencia" pretende combatir la violencia política contra las mujeres en el presente y evitar que se produzca en el futuro trabajando directamente con las mujeres de los partidos políticos para desarrollar colectivamente soluciones que ayuden a prevenir y combatir esta práctica. Su puesta en marcha se centra en capacitar a las mujeres dentro del ámbito de los partidos, formándolas para identificar la violencia contra las mujeres en política (VCMP) y denunciar su ocurrencia, así como organizar acciones internas de prevención.

El Observatorio de la Violencia Política contra las Mujeres está formado por varias instituciones, entre ellas: Transparência Eleitoral Brasil, Grupo LiderA (IDP) y Grupo Ágora (UFC). Se trata de una iniciativa pionera en el país y reconocida en el extranjero, como por ejemplo por la Unión Europea y la Comisión Interamericana de Mujeres de la Organización de Estados Americanos (OEA).

Para desarrollar el proyecto, se celebraron reuniones tipo bootcamp con mujeres de todos los partidos políticos en las cinco regiones del país. El objetivo de esta iniciativa de ámbito nacional es movilizar a las mujeres de los partidos políticos y desarrollar conjuntamente estrategias para prevenir y combatir la violencia política contra las mujeres. Esta publicación reúne toda la información sobre el proyecto y está pensada para inspirar nuevas iniciativas de diálogo entre los partidos políticos y la sociedad civil.
