Authors: Maurel María del Carmen , Monti Cristina Mónica
Published: April 2024

El artículo surge del proyecto de investigación “La evaluación: una herramienta para la mejora de la práctica pedagógica”. El estudio se realizó en las cátedras Física I y Algoritmos y estructura de datos de la carrera de Ingeniería en Sistemas de Información de la Universidad Tecnológica Nacional. El trabajo consiste en una indagación empírica de carácter cualitativo. Para el análisis de los datos, se utilizaron diferentes herramientas metodológicas: Análisis documental, relatos de las prácticas en forma de entrevistas y encuestas, observaciones de aulas virtuales y talleres de validación de resultados.  Entre las conclusiones más significativas, surge que hay profesores que manejan cierto dominio conceptual sobre la evaluación formativa, sin embargo, se percibe que ese conocimiento no garantiza en muchos casos la transformación de sus prácticas evaluadoras. Hay propuestas metodológicas interesantes al respecto, pero su ejecución en el ámbito académico se ve muy acotada favoreciendo prácticas evaluativas cotidianas, rutinarias y estrechas.

Epithelial ovarian cancer (EOC) is one of the leading causes of cancer-related death in women worldwide, and is characterized by a high rate of recurrence after surgery and chemotherapy. We sought to implement a circulating tumor DNA (ctDNA)–based blood test for more accurate post-operative surveillance of this disease. We analyzed 264 plasma samples collected between June 2016 and September 2021 from 63 EOC patients using tumor-guided plasma cell-free DNA analysis to detect residual disease after treatment. Assay specificity was verified using cross-patient analysis of 1,195 control samples. ctDNA was detected in 51 of 55 (93%) samples at diagnosis, and 18 of 18 (100%) samples at progression. Positive ctDNA in the last on-treatment sample was associated with rapid progression (median 1.02 versus 3.38 yr, HR = 5.63,P< 0.001) and reduced overall survival (median 2.31 versus NR yr, HR = 8.22,P< 0.001) in patients with high-grade serous cancer. In the case of 12 patients, ctDNA assays detected progression earlier than standard surveillance, with a median lead time of 5.9 mo. To approach the physical limits of ctDNA detection, five patients were analyzed using ultra-sensitive assays interrogating 479–1,856 tumor mutations, capable of tracking ctDNA fractions down to 0.0004%. Our results demonstrate that ctDNA assays achieve high sensitivity and specificity in detecting post-operative residual disease in EOC.
Tracing the “Infectious Criminal”: A Genealogy of HIV Criminalization and Infectious Injustice in Finland
Authors: Kela Juulia
Published: April 2024

This article examines the junction of state healthcare and punishment through HIV criminalization. By problematizing the application of criminal law to HIV in Finland, the study locates a genealogy of the “infectious criminal” – a figure at the cusp of these two forms of state power. The article traces how this figure, evoked in official debates from the early 20th century onwards, justified punitive measures to control marginalized people, from poor merchants to prisoners-of-war, sex workers, vagrants, and later, migrants. Drawing on parliamentary archives, the article asks how punishment and existing social injustices are narrated, maintained, and connected. Revealing a continuum of punishment and healthcare, HIV criminalization – especially within a nation deemed exceptionally non-punitive and welfare-oriented – is a crucial point from which to examine the connections of social injustice and criminal justice.

Upper limb amputations are highly impairing injuries that can substantially limit the quality of life of a person. The most advanced dexterous prosthetic hands have remarkable mechanical features. However, in most cases, the control systems are a simple extension of basic control protocols, making the use of the prosthesis not intuitive and sometimes complex. Furthermore, the cost of dexterous prosthetic hands is often prohibitive, especially for the pediatric population and developing countries. 3D-printed hand prostheses can represent an opportunity for the future. Open 3D models are increasingly being released, even for dexterous prostheses that are capable of moving each finger individually and actively rotating the thumb. However, the usage and testing of such devices by hand amputees (using electromyography and classification methods) is not well explored. This article aims to investigate the usage of a cost-effective system composed of a 3D-printed hand prosthesis and a low-cost myo electric armband. Two subjects with trans-radial amputation were asked to wear a custom-made socket supporting the Hand and the Thalmic Labs Myo armband. Afterward, the subjects were asked to control and use the prosthetic and to grasp several objects by attempting to perform a set of different hand gestures. Both the Hand and the Myo armband performed well during the test, which is encouraging considering that the Hand was developed as a research platform. The results are promising and show the feasibility of the multifunction control of dexterous 3D- printed hand prostheses based on low-cost setups. Factors such as the level of the amputation, neuromuscular fatigue, and mechanical limitations of the 3D-printed hand prosthesis can influence the performance of the setup. Practical aspects such as usability and robustness will need to be addressed for successful application in daily life.

In this fast-paced world, the number of deaths due to the accident is growing at an expeditious rate. Major reasons for these accidents are rash driving, drowsiness, drunken driving, carelessness, etc. An indicator of survival rates after detecting accidents is the time between the occurrence of accidents and the advent of medical care to the victim. The rapid growth of technology has made everything more facile and this advancement in technology additionally increased accidents. Due to this delayed medical attention, the accident victims might die as well. As a solution to these problems, a system that detects road accidents and will provide an alert message through images to the most proximate hospital immediately is introduced. Whenever an accident occurs, the common man can use this app by uploading images of the accident and immediately report it to the nearby hospital and gathering information from RTO database.
Structure Visualization of 4-DASPI–Cucurbituril Supramolecular Complex to Predict the Solvatochromic Shift of Absorption Spectrum
Authors: Stepko A.S. , Lebedev-Stepanov P.V.
Published: April 2024

The study of supramolecular “host-guest” complexes in solutions is of fundamental and practical significance. The structures and formation enthalpy of supramolecular complexes for the 4-DASPI dye with two cavitands (cucurbit[6]uril and cucurbit[7]uril) have been obtained by the TDDFT quantum chemistry method with a camb3lyp basis. It was shown by visualization of the structures that the size of cucurbit[6]uril is too small and doesn’t allow the dye chromophore to penetrate into the cavitand cavity while the dye stays in the ground state, but the formation of an external complex is possible. On the contrary, formation of an inclusion complex with the cucurbit[7]uril is energetically favorable, and the dye chromophore penetrates into the cavity. Visualization of the complex structure allows us to determine the chromophore position relative to the given cavitand cavity, and thus we can predict the changes in the dye spectra due to complexation. The theoretical results of the work are in good correlation with the experiment.

Published: April 2024

The purpose of this work is to establish the possibility of using the finite element analysis method to study complex stress states in case of a femur fracture with subsequent data visualization. Experimental data were obtained on a solid-state mathematical parametric model of the femur, created on the basis of computer tomogram data, and repeating studies on native biological objects. As a result of mathematical modeling, oblique transverse and helical fractures of the diaphysis of the femur with elements of helical deformation were studied. The application of finite element analysis made it possible to visualize and predict the stresses arising in bone tissue under the impact of a blunt solid object in a complex stress state and the morphological features of femoral shaft fractures under different torsional loading forces of the proximal part of the femur. The data on the mechanism and morphology of the femoral shaft fracture obtained during modeling are confirmed by the results of original full-scale experiments.

Published: April 2024

This article analyzes the historical development of the institution of bankruptcy, highlights its evolutionary changes in the context of the general principles of humanism. It is noted that in the past bankruptcy was considered a serious crime, but in the 19th century a transformation of approaches was observed, where harsh sanctions gave way to the humanization of society. Changes in modern trends are considered, pointing to the rejection of the separation of bankruptcy systems and emphasizing the concept of an effective system of insolvency law and bankruptcy prevention. The article is aimed at a retrospective analysis and highlighting of key aspects of the evolution of the bankruptcy institution with an emphasis on the transition from a punitive to a compensatory concept and the importance of preventive measures. The period from the Middle Ages to the beginning of the 20th century was considered. The norms and legislative acts of France, Germany, and Italy are analyzed, highlighting the variety of approaches to determining the insolvency and responsibility of debtors. In particular, the laws issued in the 16th century, which for the first time distinguished between unfortunate and malicious insolvency, are examined. An important stage is the analysis of the period of bankruptcy law reforms in the 19th century, when a change in the direction of legislation on business preservation and social protection of employees of debtor enterprises is noted. The article also notes reforms in French and German legislation aimed at balancing liquidation and rehabilitation procedures. The general conclusion is that the history of bankruptcy is closely related to the social organization of the country and the financial challenges of its era.

Authors: Abuelhaija Ashraf , Saleh Gameel , Issa Samer , Nashwan Osama , Salama Sanaa
Published: April 2024

This article introduces two designs for dual-tuned built-in radio-frequency coil current sensing in 7-Tesla magnetic resonance imaging based on the current forcing property of the quarter-wave transmission line. The first design offers dual-tuned built-in coil current sensing at 1H/23Na resonant frequencies to probe the coil current consecutively at 298 MHz and 78.8 MHz, without the need for any integrated sensor on the coil. The second design enables dual-tuned built-in coil current sensing at 1H/31P resonant frequencies to probe the coil current at 298 MHz and 120 MHz consecutively. The first design achieved good matching (<-40 dB) and low insertion loss (<0.5 dB) for 1H and 23Na magnetic resonance signals. The 1H/31P design also exhibited good matching (<-30 dB) and low insertion loss (<0.67 dB). Therefore, both designs show promising potential for monitoring current flows in dual-tuned coils at the Larmor frequencies of different atomic nuclei.

Authors: Park Seungyong , Qu Longyue , Park Min-Seok , Jung Kyung-Young
Published: April 2024

The demand for wideband circularly polarized (CP) antennas in wireless communication applications has been increasing, given that it offers reliable signals with reduced interference. In particular, planar monopole antennas are a popular choice for use in CP applications due to their compact size and ease of integration. However, achieving CP characteristics often requires complex modifications, an increased antenna size, and design complexity. To address these challenges, this study proposes a simplified radiator structure modification for CP planar monopole antennas and validates the performance of the proposed antenna for ultra-wideband (UWB) applications by conducting both frequency-domain and time-domain analyses. The size of the proposed antenna is 34 mm × 41 mm × 1.6 mm, with FR-4 as the substrate. Both the -10 dB S11 bandwidth and 6 dB axial ratio axial ratio is 3.46–5.5 GHz, with the radiation patterns in the frequency range of interest being omni-directional. The proposed UWB CP antenna also yields decent antenna performance in time-domain analyses, such as the antenna fidelity factor and the system fidelity factor.
Near-Field Radar Equation Based on Fresnel Diffraction Formula to Detect Short-Ranged Targets for Automotive Radar
Authors: Oh Kyoung-Sub , Qin Pei-Yuan , Seo Dong-Wook
Published: April 2024

Although the classic radar equation has been widely used to analyze the link budget of an automotive radar, it is valid only when the targets are located in the far-field region of the transmitted field and the receiving antenna is located in the far-field region of the scattered field. This paper confirms this hypothesis using measured and simulated data for short-range radars. Furthermore, a novel radar equation based on the Fresnel diffraction formula is proposed for application in situations where the receiving antenna is located in the radiative near-field region (or Fresnel region) of a target, but the target is situated in the far-field region of the transmitting antenna. In addition, the proposed radar equation is assessed by comparing the measured and simulated data.
Heuristic Incremental Theory of Diffraction for a Wedge with Impedance Surfaces
Authors: Kim Jun-Seon , Lee Hyun-Soo , Park Jong-Eon , Seo Dong-Wook
Published: April 2024

This paper proposes a novel incremental theory of diffraction (ITD) formulation to calculate the fringe field from a wedge characterized by impedance surfaces and arbitrary exterior angles. The ITD formula was originally based on the Fourier transform pair relationship between the solution for the canonical wedge problem and incremental field contribution. However, this procedure can be utilized to report the ITD formula only for planar and half-planar impedance surfaces. Therefore, this paper develops a heuristic ITD formula by conceptually deriving the incremental diffracted field contribution from the uniform theory of diffraction coefficient and inferring the physical optics edge-diffracted field contribution from the terms related to the incidence shadow and reflection shadow boundaries. The proposed formula is applied to simple triangular impedance cylinder and disk models with impedance surfaces, and the results are compared with those of the method-of-moment and VIRAF’s ITD solver to show that is performs similar to the former and better than the latter.

Published: April 2024

Magnetoelectric dipoles have attracted global research attention due to its broadband, unidirectional, and high front-to-back ratio characteristics. This study implemented a co-simulation between a basic magnetoelectric dipole and its front feeding circuit through the step-by-step numerical extraction of its equivalent circuit model equipped with lumped and frequency-independent components. First, the series resonance subcircuit was derived from the series resonance point in the impedance of the magnetoelectric dipole. Second, the parallel resonance sub-circuit was achieved based on the parallel resonance point. By combining the series and parallel sub-circuits according to the sequence of their resonance frequency, the final form of the equivalent circuit for the basic magnetoelectric dipole was realized. Furthermore, to obtain the component values of the proposed circuit, a numerical fitting technique was adopted to accurately match the input impedance of the antenna and its equivalent circuit. A comparison of the circuit and antenna electromagnetic simulations showed that they agreed well with each other. Hence, the correctness and feasibility of the extraction process were verified. The overall results showed that the proposed circuit model can easily substitute for a basic magnetoelectric dipole in the implementation of antenna/circuit cosimulation in circuit simulators.

The huge number of information threats and their complexity prompts research and modeling of new methodologies and information protection systems. The development and improvement of information and cyber security systems includes the creation and processing of mathematical models using information technologies. This article is a follow-up study on the application of mathematical methods and technologies in cyber security, namely: methods of cluster analysis. The modern development of computer technology and the growth of their power have contributed to the wide implementation of Data Mining algorithms for processing large volumes of information in various fields of society and science, in particular in the field of cyber security. Cluster analysis allows the set to be divided into subsets, so that the elements of each subset are similar to each other, and the elements of different subsets are the most different. This provides an opportunity to eliminate the shortcomings of the qualitative approach in assessing information risks. The paper reviews scientific sources regarding the applied aspect of the application of clustering methods in security systems, because timely forecasting of possible incidents allows you to manage information risks and make effective decisions to ensure confidentiality, availability and integrity of information. The stages of the clustering procedure are characterized, the issues of choosing the distance measure and the similarity measure for the objects under study are highlighted. The comparative characteristics of the most popular methods of cluster analysis are presented: the “nearest neighbor” algorithm, “k-means”, “fuzzy c-means”, “cosine similarity”, their advantages and disadvantages are defined. This study can be useful and used in the educational process of students of the specialty 125 “Cyber security and information protection”.

The dual challenge of geopolitics/geoeconomics and South Korea’s economic security strategy: Continuity and Change
Authors:   The Korean Association Of Area Studies, Lee Seungjoo
Published: April 2024

This article sheds light on the dual nature of South Korea's economic security strategy: long-term continuity and changes that reflect structural shifts in the internal and external environment. South Korea’s economic security strategy has undergone several phases of transformation from the early 1960s to the present, while maintaining continuity. The continuities of South Korea’s economic security strategy are the combination of geopolitics and geo-economic responses, the lack of economic coercion, the mercantilist character, and the industrial policy-based strategy. One can also find a change in South Korea’s economic security strategy in that it closely integrates high technology into its economic security strategy. Specifically, it involves reducing vulnerabilities in the supply chain of high-tech industries, strengthening high-tech capabilities, and combining industrial policy and high-tech strategies.
Improving the System for Early Settlement of North Korean Refugees
Authors:   The Korean Association Of Area Studies, Oh Hyung Keun , Yeo Hyun Chul
Published: April 2024

North Korea under the socialist system has a structure in which the type and site of work are determined according to the central policy rather than employment other than individual ability in choosing jobs for its residents. Since it is important for North Korea, which is pursuing a planned economy, to achieve production goals set in accordance with each economic sector's plan, groups take precedence over individual abilities at the work site, and there are few changes in the working environment, such as turnover or relocation of work, so efforts or activities to equip individuals with competitiveness in their activities are of little significance. Most of the North Korean defectors who entered South Korea were subordinated in such a working environment at the time of their repatriation. South Korea is making great efforts to increase the competitiveness of individuals seeking employment because economic activities are determined according to the principle of marketism. North Korean defectors who were accustomed to the socialist planned economy system had jobs, but it is difficult to settle smoothly in that employment for adaptation to South Korean society is mainly achieved through competition with the general public. With 34,000 North Korean defectors now, their successful settlement in South Korean society as a priming water for the unification of the Korean Peninsula is drawing attention as a very important issue. This is because economic independence and income are achieved through employment, and the settlement of economic stability leads to stable participation in South Korean society. The economic activities of North Korean defectors will reduce the loss of social costs for them in South Korean society as a whole, which will further benefit the South Korean economy, and serve as a cornerstone for future unification of the two Koreas. Therefore, this study aims to suggest the possibility of obtaining compulsory employment-type qualifications in consideration of educational background and career in North Korea as an institutional improvement plan for early settlement based on economic stability in South Korea.
Southeast Asia's Survival Strategies in Great Power Competition: A Historical Perspective and Diachronic Comparison
Authors:   The Korean Association Of Area Studies, Lee Jaehyon
Published: April 2024

As the U.S.-China rivalry intensifies in Southeast Asia, Southeast Asian perspectives on the U.S.-China strategic competition have attracted much attention. This article attempts to analyze the current perspectives of Southeast Asian countries on the U.S., China, and U.S.-China rivalry based on their historical experiences, moving between the experiences of specific countries and the collective experience of ASEAN as a whole. It analyzes Southeast Asian perspectives and strategies on the US-China rivalry through a historical examination of strategies during the Cold War and post-Cold War periods. In addition, this study takes an inductive approach by observing the behaviors of Southeast Asian countries and then abstracting these behaviors, rather than starting from existing theories and interpreting the behaviors of Southeast Asian countries based on these theories. In conclusion, Southeast Asian countries, individually and collectively, have deployed and continue to deploy a combination of realistic but flexible responses such as hedging to great powers. This article demonstrates that these strategies overlap with institutionalist approach, such as the ASEAN-centered multilateralism mostly exercised during the post-Cold War era.
Bringing Political Economy Back In: ‘Just Transition’ and Distributive Conflict
Authors:   The Korean Association Of Area Studies, Kim Hyun Kyoung
Published: April 2024

The issue of climate change in political science has mainly been addressed at the international or global level, viewing environmental sustainability as a public good, and focusing on why intergovernmental cooperation to address climate change has often failed. However, it is necessary not only to analyze climate change at the global level but also to examine them at the domestic level, focusing on the conflicts of interest among various actors. With the widespread recognition that solving climate issues and transitioning to sustainable energy are inseparable, the recently emerged concept of 'Just Transition' is a suitable topic for approaching through frameworks developed in international political economy and comparative political economy. This paper explores how the issue of just transition intersects with important research in international political economy such as trade politics, as well as with social protection and welfare politics in comparative political economy. It argues that analyzing political conflicts surrounding just transition from a political-economic perspective is essential to establish effective governance for climate change mitigation.

The conversion decay w® p0e+e- with the CMD-3 detector on the VEPP-2000 electron-positron collider VEPP-2000 at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences was investigated. The data from the first scan were used in the work, which corresponded to an integral brightness of around 10 pb–1 in the energy range of 660 to 840 MeV in the center of mass system. The 1113 ± 37 signal events were detected. The product of the relative decay probability and ω-meson width G(w® e+e- ) × Br(w® p0e+e- ) = (4, 20 ± 0,12 ± 0, 25) ×10-7 MeV, as well branching ratio Br(w® p0e+e- ) = (6, 78 ± 0,19 ± 0, 40) ×10-4 are measured with better precision than the world average.

We present the results of experimental studies of electron content in the ionosphere over the territory of the Republic of Belarus based on data from global navigation satellite systems. The results of measurements of the precise positioning system of the Republic of Belarus and navigation data of GPS satellites in RINEX format were used as input data. Expressions for calculation of the total electron content using the two-frequency method and a combination of measurements by phase and code delays are given. Algorithms for eliminating cycle slip and determining differential code biases are used. Examples of calculating the vertical electron content over the Republic of Belarus at different moments of time are demonstrated. The obtained results are reasonable to use in monitoring of the ionosphere in order to provide reliable operation of radio systems, detection of ionospheric anomalies of natural and artificial origin, as well as forecasting of natural phenomena on their basis.
La paz en el espejo del constitucionalismo colombiano: la promesa incómoda de la Constituyente de 1991 y su resignificación en el constitucionalismo de la transición
Authors: Luna Tania
Published: April 2024

Peace is a right and a duty of obligatory compliance with the literal wording of Article 22 of the 1991 Political Constitution. Its arrival in Colombian constitutionalism is commonly presented as a rupture resulting from a national scenario of consensus and generalized clamor for peace in the early 1990s. However, although the right to peace was included for the first time as a right in the 1991 Constitution, peace as a constitutional value has been present as a quest in the history of Colombian constitutionalism and has been recurrently appealed to in moments of constitutional change in which the law has reclaimed from violence its role as organizer and recuperator of the thread of time. The text presented here defends the central idea that the Colombian Constitutional Court re-signified the constituent history around peace in times of transition and the duty of memory around the 2016 Peace Agreement, choosing a romanticized and foundational version of the past that freezes in time other pasts, subjects and alternative visions of peace.
Saúde, Sociedade e Meio Ambiente: ensaios preliminares

O momento em que se intensifica o debate mundial em torno da Agenda 2030 e os Objetivos do Desenvolvimento Sustentável (ODS) coincide com a ocorrência de pandemias que vêm causando graves danos em todo o mundo e desafiam a humanidade sobre o modo de como enfrentá-las, além de obrigar-nos a refletir e a agir rapidamente sobre suas causas e consequências. Elas chegam em um cenário mundial em que as pessoas conhecem e vivenciam, cada vez mais de perto, os efeitos nefastos de suas ações sobre o ambiente em que vivem. Ações e modos de vida que resultam em desigualdades estruturais, exploração econômica, migração crescente, mudanças climáticas e perda de biodiversidade, e até mesmo crimes ambientais.

Nesse contexto, movimentos fortes e determinados devem revestir-se de caráter imediato na busca pela transformação das sociedades, das economias e da relação humana com o meio ambiente. Por outro lado, as intervenções transformadoras, sejam elas políticas ou programáticas, necessitam ser avaliadas por meio de abordagens também abrangentes e, portanto, comprometidas com a análise dos seus efeitos sobre a saúde, a economia, a cultura e o meio ambiente, considerando igualmente os ciclos demográficos em diferentes regiões do mundo.

Atentos a esse cenário de transformações necessárias às intervenções, entre as quais devem estar incluídas investigações e avaliações da sua implementação e efetividade, a Linha Editorial Internacional de Apoio aos Sistemas de Saúde – LEIASS apresenta a seus leitores uma contribuição para o amadurecimento dessas diretrizes. Esperamos, por meio desta publicação, voltada à divulgação de ensaios teóricos e proposições metodológicas, que ela contribua para a conciliação e a integração de dimensões aparentemente desconexas dessas ações e que, diante da complexidade dos desafios nacionais e globais, ilumine esse debate. 

Esta edição é, portanto, composta por textos de colaboradores, docentes e pesquisadores, que apresentam ensaios, reflexões e estudos relativos à saúde global e às inter-relações estabelecidas entre o modo de viver das sociedades e os sistemas naturais. Ainda, abordam intervenções cujas perguntas avaliativas demonstram a amplitude e a abrangência que consideram a complexidade de suas dimensões.
Saúde global, bioética e direito humano à água: reflexões necessárias à saúde coletiva
Authors: Lopes Rayssa Horácio , Silva Cícera Renata Diniz Vieira , Silva Ísis de Siqueira
Published: April 2024

A desigualdade no acesso à água é discutida como um dos exemplos da profunda situação
de crise humanitária vivenciada em caráter global, que fere os direitos humanos
fundamentais e afeta especialmente os mais pobres e vulnerabilizados. Este ensaio
teórico pretende contribuir para essa discussão a partir de diálogos e reflexões de estudiosos
das áreas baseados na teorização de autores implicados nesses debates. O texto
está estruturado em seis seções, a saber: “Globalização e saúde global em um mundo
desigual”; “Considerações sobre a ética ambiental”; “Bioética: de Potter às reflexões
latino-americanas”; “Diálogo sobre os direitos humanos”; “Direitos humanos para todos
ou para ‘humanos direitos'?”; e “Por uma saúde coletiva emancipatória no alcance do
direito à água de qualidade”. Com tais reflexões, as autoras propõem um olhar crítico,
implicado e responsável da saúde coletiva acerca do direito à água de qualidade para
todos, considerando-o um mandatário bioético para o alcance de uma saúde global.
Comunidade dos Países de Língua Portuguesa e Determinantes Sociais da Saúde

Published: April 2024

O Conselho Nacional de Secretários de Saúde (Conass) e o Instituto de Higiene e Medicina Tropical da Universidade Nova de Lisboa (IHMT), de Portugal, lançaram hoje, durante a Assembleia do Conselho, o mais recente volume da Série Linha Editorial Internacional de Apoio aos Sistemas de Saúde (Leiass). Esta obra, resultado de uma colaboração sem precedentes entre as duas instituições, examina os Determinantes Sociais da Saúde (DSS) no contexto da Comunidade dos Países de Língua Portuguesa (CPLP).

Intitulado "Determinantes Sociais da Saúde na CPLP: Uma Análise Abrangente", o livro destaca a importância dos DSS como um conjunto de fatores que influenciam tanto positiva quanto negativamente a saúde de indivíduos, comunidades e populações inteiras. Escrito por uma equipe internacional de especialistas em saúde pública e políticas de saúde, esta obra é uma contribuição significativa para a compreensão e o enfrentamento das desigualdades em saúde dentro da CPLP.

Ao longo de seus 14 capítulos, o livro aborda uma variedade de tópicos pertinentes, desde a análise das diferenças sociodemográficas e de saúde entre os países membros, até discussões sobre intervenções políticas eficazes para promover a equidade em saúde. Os capítulos também exploram questões específicas, como a violência de gênero, a cobertura vacinal, e os impactos das mudanças climáticas na saúde.
