Prevenção de Ataques em Sistemas Distribuídos via Análise de Intervalos
Authors: Paisante Vitor Mendes , Saggioro Luiz Felipe Zafra , Rodrigues Raphael Ernani , Oliveira Leonardo Barbosa , Pereira Fernando Magno Quintão
Published: July 2022

A análise de largura de variáveis determina o maior e menor valores que cada variável inteira de um programa pode assumir durante a sua execução. Tal técnica é de suma importância para detectar vulnerabilidades em programas mas, até o momento, não existe abordagem que aplique essa análise em sistemas distribuídos. Tal omissão é séria, uma vez que esse tipo de sistema é alvo comum de ataques de software. O objetivo deste artigo é preencher tal lacuna. Valendo-nos de um algoritmo recente para inferir protocolos de comunicação, nós projetamos, implementamos e testamos uma análise de largura de variáveis para sistemas distribuídos. Nosso algoritmo, ao prover uma visão holística do sistema distribuído, é mais preciso que analisar cada parte daquele sistema separadamente. Demonstramos tal fato via uma série de exemplos e experimentos realizados sobre os programas presentes em SPEC CPU 2006. Um protótipo de nossa ferramenta, implementado sobre o compilador LLVM, está disponível para escrutínio.
Controlando a Frequência de Desvios Indiretos para Bloquear Ataques ROP
Authors: Ferreira Mateus Tymburibá , Santos Filho Ailton , Feitosa Eduardo
Published: July 2022

Em função de seu vasto emprego em investidas contra sistemas computacionais modernos, proteções contra códigos maliciosos baseados na técnica denominada Return-Oriented Programming (ROP) têm sido extensamente estudadas. Apesar disso, ainda não se conhece uma solução definitiva. Este artigo demonstra que, através do controle da frequência de instruções de desvio indireto, é possível evitar a consolidação de ataques ROP. Para isso, foi desenvolvido um protótipo destinado a ambientes Linux, Windows, Android e OSX. Experimentos realizados com exploits confirmaram a eficácia do modelo proposto a um custo computacional comparável e, em alguns casos, inferior àquele alcançado por proteções correlatas.
An Ontological Approach to Mitigate Risk in Web Applications
Authors: Marques Marcius M. , Ralha Célia G.
Published: July 2022

Information Security (InfoSec) is becoming a high priority asset to support business activities, as organizations struggle to assure that data is available and secure in web applications. However, security is not a concern from the beginning of the development process, mainly because developers are not security specialists. Consequently, vulnerable systems are designed and when attacked can compromise organization's data and operations, enclosing high financial losses. Because most attacks targets the application layer, we propose an intelligent approach based on ontology to mitigate risks in web applications. An ontological approach can contribute to InfoSec knowledge dissemination and reduce the burden of implementing secure web applications on organizations. The ontology is based on the OWASP Top 10 Project, applied to reduce the gap between the application developer and the security knowledge. The proposed model is employed in the development's design phase; with more secure web applications as the outcome. The extensible and reusable developed ontology is evaluated in a prototype scenario of a web application named 'SMS Broadcast'. The results show that vulnerabilities can be reduced by increasing the security awareness of web developers during the application development process.
Software implementation of SHA-3 family using AVX2
Authors: Cabral Roberto , López Julio
Published: July 2022

The Keccak algorithm was the winner of the competition organized by NIST to choose the new standard hash algorithm, called SHA-3. In this work, we present the details of our software implementation in conformity with draft FIPS 202. We follow two approaches for the implementation of SHA-3, the first one computes the digest for a single message, and the other one computes in parallel four digests from four different messages. The performance for the single implementation was accelerated using vector instructions of 128/256 bits, and it is as fast as the best implementation optimized for 64 bits published on eBASH. The parallel implementation is about 2.5 faster than the single message implementation. The cryptographic primitive extendable-output functions, which is part of the draft FIPS 202, were also implemented.
Autenticação contínua para smartphones baseada em assinatura acústica
Authors: Colomé Marcelo da Luz , Nunes Raul Ceretta
Published: July 2022

Com o aumento de dados e informações sensíveis armazenados nos smartphones, controlar o acesso aos dispositivos é essencial para redução de riscos. Neste sentido diferentes mecanismos de autenticação tem sido explorados, tal como o uso de senhas ou gestos. Entretanto, os usuários costumam utilizar combinações ou gestos facilmente reproduzíveis, o que têm estimulado a perquisa por métodos de autenticação contínua baseados na interação do usuário e que executam em background. Este artigo propõe um novo método de autenticação contínua baseado em assinatura acústica produzida a partir da interação usuário-smartphone.
A Survey on Tools and Techniques for the Programming and Verification of Secure Cryptographic Software
Authors: Braga Alexandre , Dahab Ricardo
Published: July 2022

This paper contributes to broaden the discussion on tools and techniques in cryptographic programming and verification. The paper accomplishes three goals: (i) surveys recent advances in supporting tools for cryptographic software programming and verification; (ii) associates these tools to current security practices; and (iii) organizes their use into software programming and verification steps. The paper concludes that there is no single tool for secure development of cryptographic software. Instead, only a well-crafted toolkit can cover the whole landscape of secure cryptographic software coding and verification.
Modelo de ativação multi-domínios de papéis RBAC usando controle de acesso baseado em atributos
Authors: Abreu Junior Vilmar , Santin Altair Olivo
Published: July 2022

Este artigo apresenta um modelo de controle de acesso baseado em atributos (ABAC) com ativação única (SRA) de papéis RBAC em múltiplos domínios. A ativação de papéis entre os domínios é transparente para o usuário, análoga ao Single Sign-On da autenticação. A autonomia do administrador na definição das permissões de cada papel é mantida em cada domínio. Foi implementado um protótipo integrando XACML com papéis, separações de tarefas e sessões do RBAC, utilizando autorizações OAuth em ambiente de web services RESTFul. As avaliações do protótipo mostraram o mínimo de impacto no tempo de resposta do SRA em relação a um domínioúnico, observado em requisições simultâneas de acesso.
Investigando o uso de Características na Detecção de URLs Maliciosas
Authors: Bezzera Maria Azevedo , Feitosa Eduardo
Published: July 2022

URLs maliciosas tornaram-se um canal poderoso para atividades criminosas na Internet. Embora as atuais soluções para verificação de URLs apresentem altas taxas de precisão, com resultados bem ajustados, um questionamento pode e deve ser feito: será que realmente é possível ou factível se obter percentuais beirando 100% de precisão nessas soluções? Neste sentido, este artigo conduz uma investigação de características, bases e formatos de URLs, visando mostrar que os resultados de validação e verificação de URLs são bastante dependentes de certos aspectos e fatores. Através da extração de características (léxicas, DNS e outras), diretamente da URL, algoritmos de aprendizagem foram empregados para questionar a influência dessas características no processo de validação e verificação de URLs. Assim, quatro (4) hipóteses foram elaboradas e a avaliação mostra que é possível discordar dos resultados de vários trabalhos já existentes na literatura.
Teclanômade: Uma solução de autenticação para usuários de dispositivos inteligentes baseada em Teclados Nômades
Authors: Neto Antonio L. Maia , Fernandes Artur Luis , Martins Frederico , Melo Leandro T. C. , Cotta Leonardo , Saggioro Luiz Felipe Z. , Loureiro Antonio A. F. , Oliveira Leonardo B.
Published: July 2022

Smart devices são cada vez mais presentes em nossas vidas. A relevância crescente desses dispositivos torna a concepção de mecanismos de autenticação efetivos uma questão crucial. Neste trabalho, sustentamos que propostas "estado da arte" são vulneráveis a ataques conhecidos ou não são capazes de atender as demandas de usabilidade. Assim, para abordar este problema, propusemos o Teclanômade, um esquema de autenticação de usuários em dispositivos baseado em teclados itinerantes. Quando comparado às propostas existentes, o Teclanômade é capaz de aprimorar a usabilidade ao manter a posição relativa das teclas igual à dos teclados tradicionais. O aumento da privacidade, por sua vez, é fruto da natureza nômade do teclado. Mais precisamente, a privacidade advém do fato de que as teclas aparecem em posições distintas da tela cada vez que o teclado é acionado. Nossos resultados indicam que a sobrecarga resultante do Teclanômade– no caso, o atraso na entrada do usuário para fins de autenticação – é, em média, de apenas 0,5 segundo.
Atualização Reversa: Garantindo Consistência de Estados em Redes Definidas por Software
Authors: Mattos Diogo Menezes Ferrazani , Duarte Otto Carlos Muniz Bandeira
Published: July 2022

A aplicação de novas políticas de segurança e a atualização de políticas já existentes em uma rede são causas comuns de instabilidade no funcionamento da rede, levando à interrupção de serviços e, até mesmo, a estados transitórios vulneráveis da configuração da rede. Durante o processo de instalação de políticas de segurança, a rede pode passar por estados inconsistentes que podem levá-la a comportamentos inesperados. Este artigo propõe um esquema consistente para o processo de atualização de políticas em Redes Definidas por Software, chamado de Atualização Reversa. O artigo prova a consistência da proposta através de um modelo formal. Assim, as principais contribuições deste artigo são: (i) a generalização do conceito de consistência por pacote no plano de dados de uma Rede Definida por Software e (ii) o esquema consistente proposto de atualização de políticas. Um simulador de Redes Definidas por Software foi desenvolvido e validado. A simulação de um cenário de uma aplicação de política de segurança, em uma topologia real de rede, mostra que a sobrecarga gerada pelo esquema proposto é muito baixa. Além disso, os resultados comprovam que o processo de Atualização Reversa proposto é bem mais rápido que a Atualização de Duas Fases proposta na literatura.
IntelFlow: Towards adding Cyber Threat Intelligence to Software Defined Networks
Authors: Ancieta Javier Richard Quinto , Rothenberg Christian Esteve
Published: July 2022

Security is a major concern in computer networking, which faces increasing threats as the commercial Internet and related economies continue to grow. Our work aims to explore advances in Cyber Threat Intelligence (CTI) in the context of Software Defined Networking (SDN). More specifically, we propose IntelFlow, an intelligence detection system for Software Defined Networking (SDN) that follows a proactive approach using OpenFlow to deploy countermeasures to the threats learned through a distributed intelligence plane. We show through a proof of concept implementation that the proposed system is capable of delivering a number of benefits in terms of effectiveness, altogether contributing to the security of modern computer network designs.
Criptografia Baseada em Identidade: Uma Análise Comparativa sob a Perspectiva da Internet das Coisas
Authors: Maia Neto Antonio L. , Nogueira Michele , Patil Harsh Kupwade , Cunha Ítalo , Loureiro Antonio A. F. , Oliveira Leonardo B.
Published: July 2022

Identity-Based Cryptography (IBC) employs user's identity as public key, eliminating digital certificates. IBC is promising in constrained environments as Internet of Things (IoT) due to its benefits, such as facilitating public key management. However, different aspects on IBC (e.g. the need for bilinear pairing) require attention when applied to IoT in order to meet basic security requirements on these environments. This paper presents a comparative analysis of identity-based cryptosystems considering their application in IoT. The main characteristics of IoT serve as reference for the analysis. Hence, this paper contributes giving an overview about the benefits and drawbacks of the main identity-based cryptosystems on IoT.
Control Flow Protection Against Return Oriented Attacks
Authors: Rincón Álvaro , Boccardo Davidson , Pirmez Luci , Rust Luiz Fernando
Published: July 2022

Recent ROP (Return Oriented Programming) attacks are characterized by evading traditional protection methods, encouraging the scientific community to seek for a reliable and practical security solution. This work presents a novel technique based on control flow protection, and with a low overhead, making it suitable for constrained architectures in terms of processing, storage and energy. A prototype of the protection technique was developed and tested for ARM-Linux environment. The results show that our solution is effective and capable of preventing such ROP attacks with negligible overhead.
Customer Participation Stress In Service Encounters: Developing A Customer Participation Demands–Resources Model
Authors: Haager Stephanie , Büttgen Marion , Ates Zelal , Schumann Jan H.
Published: July 2022

Prior customer participation research has mostly focused on its positive effects and largely neglected potential negative outcomes. However, customer participation might be stressful and such customer participation stress (CPS) may have negative consequences on customers’ perceptions and behavior during the service process. This research extends previous research by investigating the stressors within the actual customer participation process as well as its negative effects. Based on a critical incident study, the authors develop a comprehensive model of CPS by adjusting the job demands-resources (JD-R) model to the customer participation context. The authors test the model with data from German retail banks’ customers (N=522). The results confirm that customers experience CPS. The adapted JDR model explains this stress, show that participation demands increase and participation resources reduce CPS. In contrast with prior research, we did not find that social support buffers but even enhances the negative effects of participation demands on CPS. Findings moreover reveal that CPS impairs customer participation. Managers can use these findings to improve their customer participation strategies according to CPS and its drivers.

Published: July 2022

This first German-language study of yoga in prison comprehensively and interdisciplinarily bundles essential findings about a widespread and yet little-known measure in the penal system. Against the background of the promising international state of research and yoga-theoretical assumptions, the question of the effectiveness of prison yoga is placed in the context of desistance research. A nationwide inventory and a longitudinal questionnaire survey in North Rhine-Westphalian prisons provide first-time data on yoga classes in the German prison system as well as perspectives and numerous suggestions for further scientific discussion and for a systematic expansion of existing yoga classes in German prisons.
Book Review: Transforming Print: Collection Development and Management for Our Connected Future
Authors: Andreadis Debra
Published: July 2022

This book provides an interesting and insightful look at the broad cross-section of print collections with digital surrogates, and supplies many good reasons why print is still valuable even with the proliferation of digital options. I would like to begin my review by taking a cue from chapter 3 (“Working Toward Human-Centered, Reparative Change”): I am a white, cisgender, able-bodied woman, and a library administrator. As the authors of that chapter state, it is important to take note of how the authors’ “identities shape this work, but also how yours informs your understanding of” (34) the work. Within that context, I found this book to provide useful examples of how print materials can be instrumental in “equity, diversity, inclusion, and social justice (EDISJ)” (118) work within libraries.
Book Review: Fundamentals of Planning and Assessment for Libraries
Authors: Busch Tammie
Published: July 2022

Many librarians do not learn much about planning or assessment in their master’s program, but are expected to engage in both as part of their job despite feeling they do not have sufficient knowledge to do so with accuracy and precision. This is what the authors of this title found in a survey conducted of librarians for whom assessment is a significant part of their job. Fundamentals of Planning and Assessment for Librarians, part of the ALA Fundamentals Series, uses concerns of survey respondents to create a solid introduction for librarians interested in learning the basics of planning and assessment. The authors have a strong pedigree as they have collaborated and published on this topic for a decade as well as designed and co-taught a planning and assessment course for an information science master’s program. Using a constructivist approach, this title seeks to provide practical, applicable information for librarians with limited knowledge of planning and assessment, or for library and information science students wanting an overview of the topic.
Book Review: Rightsizing the Academic Library Collection, Second Edition
Authors: Pope Barbara M.
Published: July 2022

Rightsizing the Academic Library Collection, Second Edition, is an update to the first edition published in 2015, which was awarded a starred review in Library Journal in 2015.1 In the first edition, Ward introduced readers to rightsizing, a tool which enables academic librarians to efficiently and effectively cull collections of little used, irrelevant materials, and reduce collection size, while retaining relevant materials to meet the “changing needs of users” (vii). Miller notes that the first edition resonated with her due to problems at her institution like Ward described. Since the first edition was published, there have been developments to support rightsizing, including forming shared print networks to maintain access to at-risk titles, thus prompting a second edition.
Milton Friedman: Life and scientific contributions
Authors: Jovanović Milan
Published: July 2022

The text is about the life and work of one of the most influential economists of the last century - Milton Friedman. The paper discusses some of Friedman's greatest contributions to economic theory and practice, starting with the earliest life of Milton Friedman, and the historical circumstances that were of decisive influence on his life. An analysis of several of Friedman's most significant works, written mainly in the years spent at the University of Chicago, examines Friedman's contribution to economic theory. Friedman's contribution to the reaffirmation of quantitative money theory and consumption analysis, controversial interpretation of the causes of the Great Depression, critique of the Phillips curve, with reference to the Keynesian-monetarist debate and Friedman's contribution to the methodology of economics are discussed. The last part of the paper presents the position on Friedman's socio-political influence on a global level. There is talk of Friedman's contribution to strengthening the concept of liberalism, affirmation of the ideas of the free market, individual freedom and personal integrity, while reducing the regulatory role of the state in the economy.

Published: July 2022

Fast development of information and communications technology also resulted in dynamic changes in banking sector. The subject of this paper is the analysis of electronic banking presence among bank clients in Montenegro. Additionally, the paper shall present the data on the use of computers and internet access in companies and at home as well as data on use of internet and mobile banking with the reference to their trends in previous years. The objective of the paper is to determine and show the advantages of the application of electronic banking both for the banks and their clients where the data from 2020 shows that during coronavirus pandemic, the number of e-banking service users in the country has grown considerably. Having in mind that electronic banking impacts the efficiency and speed of business operations between banks, banks and clients, as well in banks themselves, it is necessary to consider factors of poorer presence of Internet and mobile banking in Montenegro in comparison to other highly developed countries in Europe so that the access to and their application would improve and be more represented.
Oesophageal and gastric cancers: From epidemiology to modern treatment
Authors: Milošević Nikola , Milanović Srđan
Published: July 2022

Oesophageal and gastric cancers are among the ten most common malignancies in the world. These are diseases of the elderly population, and more common in men. These cancers are multifactorial diseases, with the influence of genetically inherited syndromes and acquired factors such as smoking, obesity, Barrett's oesophagus, and Helicobacter pylori infection. The clinical symptoms include dysphagia, weight loss, mediastinal and abdominal pain, nausea, and malaise. CT examinations of the chest, abdomen, and pelvis, and also esophagogastroduodenoscopy with biopsy and histopathological verification are needed for a complete diagnosis. The most common histological type of oesophageal cancer is squamous cell carcinoma, and most common gastric carcinoma is adenocarcinoma. Screenings for these cancers are not performed routinely, except in countries with a high incidence rate. The most widely accepted TNM classification is used to determine the stage. Oesophageal and gastric cancer treatment is multimodal and includes surgery, chemotherapy, and radiotherapy. Surgery is the first line of treatment in these cancers, especially in the local stages. Chemotherapy is used in almost all stages of the disease. Radiotherapy has its place in treatment, especially in locally advanced stages. It can be used as postoperative and preoperative radiotherapy, usually in combination with chemotherapy. Treatment of oesophageal and gastric cancers in the future will develop in the direction of advancing diagnostics, surgical procedures, immunotherapeutic agents as well as new radiotherapy techniques.

La aplicación del protocolo, la comunicación y las relaciones institucionales en el ámbito local: el caso del Ayuntamiento de Calvià.
Authors: González Marí Alejandro
Published: July 2022

Las instituciones públicas tienen el menester de responder a las necesidades que reclama la sociedad sin apelar a los partidos políticos que las gobiernan. De entre todas ellas, las corporaciones locales son las más cercanas a la ciudadanía debido a la vecindad existente entre la institución y los espacios públicos. Por ello, la imagen que emiten debe ser muy cuidada y, además, tener un propósito, no solo de transmitir un mensaje sino de aunar con él la cultura, las costumbres, los contextos con los que convive y lograr ocupar el imaginario social común que reside en los ciudadanos. El objetivo de este trabajo es investigar la importancia que adquiere la transmisión del mensaje y la imagen emitida por las instituciones públicas locales a sus ciudadanos mediante la organización de actos, cobrando una mayor importancia en la aplicación del protocolo, las relaciones institucionales y la comunicación. Siguiendo una metodología de enfoque cualitativo, se ha decidido llevar a cabo una comparación de actos homogéneos que permiten discernir entre cuáles son los aspectos destacables que intervienen en la transmisión del mensaje en función del contexto, escenografía, asistentes y ciudadanos.
Transtierro: El concepto legado por José Gaos
Authors: Córdoba Paulo
Published: July 2022

Este artículo sostiene que el concepto de transtierro, inventado por el filósofo español José Gaos, durante su exilio en México, constituye uno de sus legados filosóficos. Con la finalidad de fundamentar esta tesis, se llevarán a cabo tres pasos: 1) se abordará la noción de legado filosófico para mostrar en qué consiste ese tipo específico de legado, 2) se trazará una breve historia conceptual del transtierro, y 3) se mostrará en qué sentido el transtierro puede ser visto como uno de los legados filosóficos de Gaos. Al final, se espera dejar construido un texto que deja abierta las posibilidades de seguir pensando el transtierro en la actualidad.
Límites a la libertad de enseñanza y Ley Orgánica de Educación (LOMLOE). Un debate constitucional en permanente definición
Authors: Vivancos Comes Mariano
Published: July 2022

La reciente aprobación de la LOMLOE ha propiciado un intenso debate sobre su contenido y, muy significadamente, sobre aquellos aspectos del texto legislativo orgánico más controvertidos desde la perspectiva constitucional. Más allá de la controversia generada en torno a su singular tramitación, impulsada con suma celeridad durante la pandemia y fruto de un procedimiento legislativo técnicamente cuestionable, la crítica se ha focalizado en las novedades legales referidas a la educación concertada, el modelo pedagógico de escuela diferenciada o el recorte de la potestad directiva respecto de las titularidades privadas. El texto orgánico estatal sobredimensiona la vertiente prestacional del derecho a la educación a fuerza de limitar su intrínseco valor de libertad y nos desliza hacia un cuestionable modelo educativo estatalizante que no sólo se aparta del consenso constitucional sino que puede menoscabar seriamente el sistema de valores que fundamentan la UE. Reabriendo, en definitiva, un debate constitucional cuya resolución arrojará luz sobre aspectos determinantes del modelo educativo español, condenado a una inestabilidad crónica por un legislador estatal incapaz de forjar consensos perdurables en el tiempo.
protección a la infancia y la adolescencia desde un punto de vista competencial: evolución y límites tras la Ley Orgánica 8/2021, de 4 de junio
Authors: Sánchez Barroso Borja
Published: July 2022

La evolución histórica del concepto «menor de edad», que ha pasado de designar meros objetos de protección a auténticos sujetos de derechos y obligaciones, no ha tenido solamente un impacto sustantivo, sino también competencial. Las diferencias observadas entre la Ley Orgánica 1/1996, de 15 de enero, de protección jurídica del menor de 1996 y la reciente Ley Orgánica 8/2021, de 4 de junio, de protección integral a la infancia y la adolescencia frente a la violencia (LOPIVI) sacan a la luz retos novedosos para el deslinde de competencias estatales y autonómicas en materia de infancia y adolescencia, dentro del marco constitucional y estatutario existente. Más allá de la competencia sobre legislación civil, a la que se acogía tradicionalmente el Estado, y la competencia en materia de asistencia social, asumida por las Comunidades Autónomas, el desarrollo de la LOPIVI obliga a interpretar nuevos títulos competenciales en relación con esta materia. Alguno de ellos guarda relación con la interpretación del concepto de legislación básica en diversos ámbitos (educativo, sanitario, administrativo, etc.). Otros, los más relevantes, con el alcance de las condiciones básicas contempladas en el art. 149.1.1.ª CE. En todos estos casos, la LOPIVI ofrece certezas, pero también algunas dudas, sobre su posible cobertura competencial. Tras analizarlas en profundidad, valoraremos la solución política alcanzada para resolverlas (al menos de forma provisional) y formularemos propuestas de interpretación futura para deslindar con mayor precisión las competencias estatales y autonómicas en materia de protección de infancia y adolescencia.
prohibición de discriminación directa por razón de sexo en la jurisprudencia del Tribunal de Estrasburgo
Authors: Agudo Zamora Miguel
Published: July 2022

Este trabajo trata la doctrina emanada de la jurisprudencia del Tribunal Europeo de Derechos Humanos que ha consagrado la prohibición de discriminación directa por razón de sexo.Se estudian en primer lugar aquellos casos de discriminación directa que han afectado a las mujeres, en ámbitos tales como el laboral y el de los beneficios sociales o las prácticas médicas. Continúa el trabajo con un apartado dedicado a la violencia de género.Posteriormente se analizan aquellos otros en los que el perjudicado ha sido el hombre en ámbitos tales como los beneficios relacionados con la tenencia de hijos, la pensión de viudedad, la prestación de servicios o las penas de prisión y el régimen penitenciario.Y la conclusión principal a la que se llega en este trabajo es que, sin poner en duda la importante labor que contra la desigualdad y la discriminación directa por razón de sexo ha desarrollado el Tribunal de Estrasburgo, en ocasiones los enfoques jurisprudenciales e incluso los importantes hallazgos interpretativos del Tribunal se han visto empañados también por estereotipos de género.Este trabajo ha sido realizado en el marco del Proyecto de Investigación RTI2018-100669-B-100 «GEN-DER: Generando una interpretación del Derecho en clave de igualdad de género», enmarcado en el Programa Estatal de I+D+i Orientada a los Retos de la Sociedad - Ministerio de Ciencia e Innovación (2019-2021).
¿Se pueden garantizar los derechos sociales? Una propuesta para la nueva Constitución chilena
Authors: Martínez Estay José Ignacio , Peredo Rojas Marcela Inés , Poyanco Bugueño Rodrigo Andrés
Published: July 2022

En el marco del proceso constituyente chileno, y ante las ideas que proponen reemplazar la actual Carta fundamental por una que considere un principio de Estado social o la justiciabilidad reforzada de los derechos sociales, el propósito del presente artículo es explicar los limites dogmáticos que encuentra la justiciabilidad de esta clase de prerrogativas y porqué una mejora de este tipo sólo podría traducirse en una mejora relativa en la exigibilidad de las prestaciones respectivas. En este marco, una mejora que respete al mismo tiempo las competencias y responsabilidades de las autoridades, los límites de la labor jurisdiccional y las características técnicas de los derechos sociales, podría consistir en la inclusión de un organismo colegiado y consultivo que, tal como en otros países, permita considerar estas demandas de forma oportuna al interior del proceso legislativo, lo que junto con respetar la necesidad de que las políticas sociales tengan un origen democrático, ayudaría a que la labor de adjudicación del juez se centre en la interpretación propiamente jurídica de las disposiciones constitucionales pertinentes.
Enmienda democrática de la Convención Americana sobre Derechos Humanos. Una propuesta de participación de la ciudadanía
Authors: Salas Cruz Armando
Published: July 2022

La Convención Americana sobre Derechos Humanos contempla el procedimiento para ser reformada. Más allá del intento fallido de 1993, el instrumento fundamental de la región en materia de derechos humanos nunca ha sido enmendado desde su entrada en vigor hace más de cuarenta años (1978). Este escenario, con sus posibles razones y consecuencias, es el que se esboza en el presente trabajo, con el propósito de replantear la interpretación del art. 76 convencional y sugerir la necesidad de la participación ciudadana en la construcción de las futuras enmiendas. La perspectiva adoptada se centra en la forma de la enmienda, de su legitimidad democrática, desde una postura que entiende que la base de la evolución general del sistema interamericano, y evolución específica del mecanismo de protección, es la reforma del texto convencional. La reforma reglamentaria, utilizada hasta ahora como técnica de cambio, es complementaria e insuficiente por sí sola.
La formación sanitaria especializada en Pediatría y sus Áreas Específicas; una perspectiva desde el médico interno residente

Published: July 2022

Our pediatric care model is a benchmark in Europe thanks to excellently trained specialists, who pay attention to child and adolescent health at all levels of care. However, an outdated training system in many aspects, also with other factors such as the shortage of paediatricians, can put the continuity of our model at risk. The objective of this study is to analyze different points of training and care work from the point of view of the pediatric resident. For this, a descriptive study has been carried out through the data collection conducting a direct form, with the majority of the main national training centers being represented, with an equitable disposition of the answers between the different years of residence. Residents who have answered our form consider generally the current 4-year program insufficient and demand the recognition of pediatric subspecialties. In turn, most of them aim to work in hospital care, which contrasts with current healthcare needs. The data exposed and argued in this study, show the need to adopt changes from training to resource managemente, so that they adapt to the new needs of national Pediatrics.

Nuestro modelo de atención pediátrica es referente a nivel europeo gracias a especialistas excelentemente formados, que prestan atención a la salud infantojuvenil en todos los niveles asistenciales. Sin embargo, un sistema formativo en muchos aspectos desactualizado junto a otros factores como el déficit de pediatras, pueden poner en riesgo la continuidad de nuestro modelo. El objetivo de este estudio es el de analizar distintos puntos de la formación y labor asistencial desde el punto de vista del residente de pediatría. Para ello, se ha realizado un estudio descriptivo a través de la recogida de datos mediante formulario directo, obteniendo respuestas de la mayoría de los principales centros formativos nacionales, con una disposición equitativa de las respuestas entre los distintos años de residencia. Los residentes que han contestado nuestro formulario consideran, de forma general, insuficiente la formación actual de 4 años y reclaman el reconocimiento de las subespecialidades pediátricas. A su vez, la mayoría tiene como objetivo trabajar en Atención Hospitalaria, lo cual contrasta con las necesidades asistenciales actuales. Los datos expuestos y argumentados en este estudio, ponen en evidencia la necesidad de adoptar cambios desde la formación hasta la planificación de recursos, de forma que se adapten a las nuevas necesidades de la Pediatría nacional.

In this article, the author conducts a study that contributes to the analysis of the limits of the permissibility of the implementation of international law on the basis of constitutions and charters of subjects of the Russian Federation. The subject of the study is the legal norms contained in the constitutions and charters of the subjects of the Russian Federation, as well as the practice of their implementation.The object of the study is the social relations that develop in the process of implementing the norms of international law in the constitutions and charters of subjects.The purpose of the study is to improve the legal norms regulating the limits of the permissibility of the implementation of international law in the constitutions and charters of the subjects of the Russian Federation. The methodological basis was formed by the methods of scientific cognition, special attention is paid to the dialectical method of state-legal and social phenomena in interaction with general scientific and private scientific methods. The result of the work is the development of a classification of constitutions and charters of the subjects of the Russian Federation, contributing to the definition of the limits of the permissibility of the implementation of international law.The presented classification will make it possible to improve the legal status of a person and a citizen faster, to exercise his rights in the context of the implementation of a completed order for social justice, taking into account the priority of national legislation over international norms. This is one of the directions set out in the Messages of the President of the Russian Federation to the Federal Assembly in 2019-2020. The proposed classification option would allow.it is faster to implement, in practical terms, the breakthrough development of the state, which is based on the constitutional idea of man as the highest value of the state, and in the science of constitutional law to provide an opportunity to implement the norms of international law in the constitutions and charters of the subjects of the Russian Federation, taking into account the limits of admissibility.
Legal characteristics of the will and expression of the will of the people in direct forms of democracy
Authors: Kravchenko Oleg Aleksandrovich
Published: July 2022

The subject of this study is the constitutional assurance of the validity of the will of the people when voting, as well as the theoretical and practical problems that arise in this case. In resolving this issue, the key is the problem of determining the nature of the will and the will of the people. The scientific problem raised concerns the correlation of the will of the people with its expression, as well as the establishment of a constitutional and legal connection between democracy and the expression of the will of the people. In practical terms, the scientific problem posed is manifested in the existence of a threat to the constitutional system in the form of the possibility of reflecting the distorted will of the people in the constitutionally significant voting results. The author suggests proceeding from the non-contractual nature of the general volitional act of the people in direct forms of democracy, which is understood as a political decision taken by a majority of votes in the absence of an agreed (unanimous) expression of the will of all citizens (the theory of real democracy). In contrast to this approach, the theory of the social contract proceeds from the contractual nature of the general volitional act of the people, which is understood as a social contract based on the agreed (unanimous) will of all citizens (the theory of ideal democracy). It is concluded that due to the non-contractual nature of the general volitional act of the people, the legal consequences of making a political decision should apply to all citizens of the state, including both those citizens who expressed their will against such a decision and those citizens who did not express their will. The novelty of the proposed provisions lies in the differentiation of the will and the will of the citizen, as well as the differentiation of the will (the general will of the people) and the will of the people (the general will of the people).
External enclosing structures of a rural house in Siberia: Soviet experience
Authors: Dranitsa Mariya Vyacheslavovna
Published: July 2022

The article is devoted to the peculiarities of the construction of low-rise houses in rural settlements of Siberia of the Soviet period. Changes in the country affected the construction of rural settlements in Siberia. Changes in the formation of rural settlements affected the external enclosing structures. The main development trends and characteristic features of external enclosing structures are determined. Prerequisites for the use of new materials for enclosing structures are described. Typical design is considered as a means of ensuring fast and high-quality construction of rural houses in Siberia, and its impact on enclosing structures revealed. The external enclosing structures in the design and construction of "exemplary" rural settlements are considered. The external enclosing structures of low-rise housing construction in Siberia during the Soviet period are considered as an object of research. The subject of the study is the methods of analysis of scientific literature and system–structural analysis of rural houses in Siberia and their external enclosing structures built in the Soviet period. The novelty lies in the fact that the changes in the construction of Siberian rural houses during the Soviet period were considered and how they affected the external enclosing structures. The main conclusions are that radical changes took place in rural settlements of Siberia during the Soviet period, this was reflected in the external enclosing structures. The traditional wooden materials were replaced by factory-made materials. At that time, they tried to unify low-rise rural houses. Standard projects were developed that could be adapted to the Siberian climatic conditions. The revision of design standards contributed to the development and implementation of new design approaches. This has led to an increase in the typological diversity of housing with various types of external enclosing structures. During this period, "exemplary" rural settlements in Siberia began to be actively designed and built, for the construction of which materials of factory-made external enclosing structures with the addition of local materials were used.

Epidemic viruses seriously affect human health and the normal operation of society, so it is particularly important to effectively kill viruses. In this work, the thermal performance of a thermoelectric air disinfection system are studied. Utilizing the characteristics of semiconductor thermoelectric sheets with both cold and hot ends, the system can increase the air temperature by heating (cound be used in sterilization), and then, reduce the temperature of the air by cooling. The measurement results show that the air temperature can be increased to 80 ℃ first, and then cooled to 35 ℃. The total energy utilization rate of the system can reach up to 1.2. In addition, combined with the measurement results and numerical calculations, the parameters such as the number of thermoelectric element series, input power, air flow, and boundary insulation can be used to analyze their effects on the system performance. The system may have broad potential applications in public health, medical care, and household disinfection.

The Laplacian-energy-like invariant of a finite simple graph is the sum of square roots of all its Laplacian eigenvalues and the incidence energy is the sum of square roots of all its signless Laplacian eigenvalues. In this paper, we give the bounds on the Laplacian-energy-like invariant and incidence energy of the corona and edge corona of two graphs. We also observe that the bounds on the Laplacian-energy-like invariant and incidence energy of the corona and edge corona are sharp when the graph is the corona or edge corona of two complete graphs.
