Análise de Política Externa
Authors: Lira-Brito Renato Victor , Melo Estevão Luiz de Lacerda Vidal Albuquerque
Published: December 2023

Neste trabalho, resenhamos a obra “Foreign Policy Analysis: a Toolbox”, um livro-texto de autoria dos professores de Ciência Política Jean-Frederic Morin e Jonathan Paquin. O livro, que faz uma apresentação sobre o campo de Análise de Política Externa, foi pensado como uma caixa de ferramentas, de onde pesquisadores e estudantes podem tirar referências, ideias e conceitos que irão auxiliá-los em suas pesquisas.  O trabalho se divide em dez capítulos, e nele são apresentadas uma série de teorias de política externa que lidam com tomadores de decisão, atores burocráticos, instituições políticas, atores sociais, a racionalidade, a cultura, e a estrutura do sistema internacional. Notamos a falta de um detalhamento maior sobre determinadas teorias e teóricos, que poderiam ter sido contextualizados de uma forma melhor, assim como de discussões mais aprofundadas sobre estudos de caso - algo que poderia ter sido melhor explorado, uma vez que o campo de análise de política externa contém diversos desses estudos. Não obstante, acreditamos que os autores tiveram sucesso em apresentar uma grande variedade de teorias e abordagens - na realidade, bem mais do que normalmente se esperaria em livros didáticos introdutórios. Isso permite que os estudantes de Relações Internacionais e Política Externa estendam a sua visão acerca de como esse campo é estudado cientificamente. Acreditamos que esse livro-texto é um ótimo auxílio didático ou mesmo um livro base para disciplinas de análise de política externa em cursos de Ciência Política ou Relações Internacionais.
Autorregulação profissional e controle
Authors: Grillo Fernanda Fontenelle
Published: December 2023

O presente estudo se propõe a explorar a autorregulação profissional no Brasil, manifestada através dos Conselhos de Fiscalização Profissional, com o objetivo de avaliar a necessidade de controle interno dessas entidades pelo Poder Executivo Federal, uma questão levantada pelo Tribunal de Contas da União. A pesquisa aborda a natureza jurídica das corporações profissionais, identificadas como entidades públicas paraestatais que operam como espaços administrativos autônomos em relação ao Poder Executivo central. A legitimidade autônoma dessas entidades, distinta da legitimidade democrática aplicada à Administração Pública em geral, é destacada. O estudo investiga ainda as características do pluricentrismo e do hibridismo da Administração Pública do século XXI, inerentes a contextos nos quais o público e o privado se mesclam, e a necessidade de superar legados do Estado Liberal, como o princípio da unidade. O trabalho também analisa como as Ordens Profissionais são tratadas no Direito comparado, com enfoque no ordenamento português, e explora os conceitos de tutela, supervisão ministerial e controle interno. A metodologia do trabalho baseou-se na análise da legislação aplicável às entidades de fiscalização do exercício profissional, as posições doutrinárias e a análise do julgamento do processo de auditoria sobre o tema pelo Tribunal de Contas da União. Os resultados indicam que a supervisão do Poder Executivo Federal e o controle interno nas corporações profissionais é inadequada, devido à falta de previsão legal, ao potencial conflito com o sistema de controle próprio já existente nos Conselhos de Fiscalização Profissional e à violação da autoadministração e autorresponsabilidade dessas entidades.

GAYA KEPEMIMPINAN PEREMPUAN SEBAGAI PEJABAT PUBLIK DI LINGKUNGAN PEMERINTAH DAERAH KABUPATEN MINAHASA
Authors: Trifena Revangelista Mambu
Published: December 2023

The aim of this research is to examine the leadership style of women as public officials in the Minahasa Regency Regional Government. The method in this research is a qualitative method with persuasive, facilitative, contributive and transformational indicators. Data analysis uses a qualitative descriptive approach starting from data reduction, data presentation and data verification. The results of the data analysis show that the leadership styles practised by public officials within the Regional Government of Minahasa Regency are persuasive, facilitative, contributive and transformational. Of these four leadership styles, the persuasive leadership style approach is more dominant. In the persuasive leadership style, female leaders seek to persuade and inspire others. Persuasive leaders do not always use authority or power to achieve obedience but instead use trust and honesty to gain followers. Persuasive leadership also reflects an empathetic and other-oriented personality. Because leaders with a persuasive style can understand the needs and psychological conditions of their followers, they can convey messages and instructions in a way that is relevant and meaningful for each individual.

Published: December 2023

This research aims to test the financial system optimization model and apparatus competency to increase village financial accountability. This research is motivated by an obstacle in the use of the financial system which is not yet optimal because it is predicted that there are still many village officials who are not yet able to use it. Descriptive and verification methods were used to test the model. This research came from 351 members of the population consisting of heads of financial affairs or financial operators in the Village Government in Tasikmalaya Regency. Sampling was carried out using a non-probability sampling technique with a purposive sampling method with the criteria of a village government that had implemented a village financial system (Siskeudeus), so the sample size in this study was 56 villages. Each village is represented by one sample person to be used as a respondent. The results of this research show that the village financial system is in good condition, ready to be used, and statistically has a significant positive effect on financial accountability. Different results were found in that the competence of village officials was deemed inadequate in the attitude category, so that this condition reduced the level of village financial accountability.

Published: December 2023

The 21st century is characterized by the development of new research innovations and technologies in agriculture which is ultimately aimed at overcoming the poverty of the world population and solving the food problem. Agricultural information plays a major role in overcoming this problem which is considered as an essential source of agriculture where the government, policymakers, decision-makers, researchers, teachers, students, scientists, managers, and farmers are the potential users (Zaman, 2002). The work deals with the study of the models of information-consulting centers in developed countries. It highlights the coordinated work of farmers, consulting services, and researchers which is shown by their mutual cooperation, sharing of research results with farmers, introduction of innovation, and a unified vision. In the above target groups (farmer-extensionist-scientistresearcher), we studied the current situation in Georgia, as a result of which gaps were identified, which prevents open, transparent, and effective cooperation between them, and mutual exchange of information and knowledge. Based on international experiences, we have proposed a model and recommendations that will contribute to the improvement of the country's agro-information systems and the effective work of the agricultural sector.
WeaveX: Nature-inspired non-planar strategies for extrusion additive manufacturing
Authors: Xu Wenpeng , Xu Hao , Zhai Xiaoya , Jiang Jingchao
Published: December 2023

In conventional 3D printing, the layer-by-layer approach leads to
mechanical weaknesses, particularly in the vertical tensile strength
(Z-axis) and the shear resistance between layers. To address this, our
study introduces a novel non-planar toolpath planning framework for
3-axis printers, named WeaveX, inspired by nature. This method
involves moving the nozzle in the XY plane while periodically adjusting
its height in the Z-axis, enhancing interlayer bonding and shear
resistance. We developed two distinct toolpath designs: Scheme 1, which
varies layer thickness, and Scheme 2, which maintains a consistent layer
thickness. These designs were closely examined to understand their
impact on toolpath width and layer thickness, considering various
parameters. Both schemes resulted in “dumbbell”-shaped toolpath
geometries, a characteristic that can be lessened by reducing print
speed. Mechanical tests revealed that objects printed using these
schemes significantly outperform traditional planar toolpath methods in
terms of mechanical strength, showing improvements of 31.9% and 67.5%
in interlayer shear resistance. Notably, these new strategies can be
combined with each other or with conventional methods, broadening their
potential applications.
On Standardized Service Interfaces for the Interoperability of Tokenized Asset Networks
Authors: Hardjono Thomas , Lipton Alexander , Pentland Alex
Published: December 2023

Many businesses seeking new capabilities that blockchains may offer are deterred from fully embracing the technology due to fears of the classic ”vendor lock-in” and platform-capture into one specific blockchain. From an asset-centric perspective, most business applications seek certain desirable functional guarantees with regard to the state of the tokenized asset on the blockchain. These new capabilities must be accessible through standardized service interfaces. The emerging tokenized asset networks based on decentralized ledger technology must integrate seamlessly into existing financial IT systems through similar standard interfaces. As such, if blockchains are to be a foundational technology in the future Web3 Internet of Value, then several classes and types of standardized APIs must be specified, published, and widely deployed by the nascent tokenized asset industry. These standard APIs must provide business applications with a single uniform interface to the many and varied blockchains today, thereby reducing business IT costs and preventing platform-capture.
Collabo: A Collaborative Machine Learning Model and its Application to the Security of Heterogeneous Medical Data in an IoT Network
Authors: Ekolle Zie Eya , Ochiai Hideki , Kohno Ryuji
Published: December 2023

With the increase in globalization, the degree of electronic
communication increases. Such an increase is also experienced by many
sectors including the medical sector, which communicates and generates
large amounts of data related to the spread of diseases as observed in
the case of the COVID-19 pandemic. This has led to the deployment of
Internet of Things (IoT) networks in many medical centers. However, one
main challenge is how to maintain the security of the data and devices
in the network. In this study, we discuss the cybersecurity risk
associated with IoT networks used for medical services and provide a
solution for protecting medical data and devices using an agent-based
approach. Unlike most conventional cybersecurity models that use agents
based on deterministic logic or independent learning agents to detect
and prevent cybersecurity attacks, we propose a cybersecurity model
using a collaborative network of learning agents, called Collabo, that
share both mutual and causal values regarding their actions on a common
security target. Our experimental results demonstrate the significance
of our model over conventional models.
Probabilistic wind power forecasting resilient to missing values: an adaptive quantile regression approach
Authors: Wen Honglin
Published: December 2023

Probabilistic wind power forecasting approaches have significantly
advanced in recent decades. However, forecasters often assume data
completeness and overlook the challenge of missing values resulting from
sensor failures, network congestion, etc. Traditionally, this issue is
addressed during the data preprocessing procedure using methods such as
deletion and imputation. Nevertheless, these ad-hoc methods pose
challenges to probabilistic wind power forecasting at both parameter
estimation and operational forecasting stages. In this paper, we propose
a resilient probabilistic forecasting approach that smoothly adapts to
missingness patterns without requiring preprocessing or retraining.
Specifically, we design an adaptive quantile regression model with
parameters capable of adapting to missing patterns, comprising two
modules. The first is a feature extraction module where weights are kept
static and biases are designed as a function of missingness patterns.
The second is a non-crossing quantile neural network module, ensuring
monotonicity of quantiles, with higher quantiles derived by adding
non-negative amounts to lower quantiles. The proposed approach is
applicable to both missing-at-random and missing-not-at-random cases.
Case studies demonstrate that our proposed approach achieves
state-of-the-art results in terms of the continuous ranked probability
score, with acceptable computational cost.
Framing cognitive machines: A sociotechnical taxonomy
Authors: Albuquerque Pedro H. , Albuquerque Sophie
Published: December 2023

Aims: we propose a sociotechnical taxonomy for the analysis of
socio-economic disruptions caused by technological innovations.
Methodology: a transdisciplinary principled approach is used to build
the taxonomy through categorization and characterization of technologies
using concepts and definitions originating from cybernetics,
occupational science, and economics. The sociotechnical taxonomy is then
used, with the help of logical propositions, to connect the
characteristics of different categories of technologies to their
socio-economic effects, for example their externalities. Results: we
offer concrete illustrations of concepts and uses, and an Industry 5.0
case study as an application of the taxonomy. We suggest that the
taxonomy can inform the analysis of opportunities and risks related to
technological disruptions, specially of those that result from the rise
of cognitive machines.
Utilidad de la tractografía por DTI para el tratamiento de tumores cerebrales supratentoriales y malformaciones arteriovenosas por radiocirugía
Authors: Bennett Colomer Carlos , Urtubia Pérez Pablo
Published: December 2023

Introducción: El tratamiento radio quirúrgico de lesiones supratentoriales conlleva el riesgo de generar déficits neurológicos secundarios al daño de tractos críticos. El uso de tractografía por DTI permite identificar estos tractos y limitar la dosis que reciben. La utilidad de esto no ha sido bien definida en la literatura. Método: Revisión sistemática narrativa de la literatura sobre integración de tractografía en planificación de tratamiento radio quirúrgico de MAVS y tumores supratentoriales, en términos de identificación de constraints (relacionando complicaciones con dosimetría dentro de determinados tractos), modificaciones de planificación inducidas por tractografía, y comparación de resultados clínicos con y sin tractografía. Resultados: Se identificaron 12 estudios, la mayor parte series retrospectivos. Se sugiere que distintos tractos presentan complicaciones a diferentes dosis: para el tracto piramidal, las complicaciones parecen aparecer sobre los 20 Gy (mayor riesgo a nivel de la cápsula interna), al igual que para la rama frontal del fascículo arcuato. La rama temporal de éste parece tener una mayor sensibilidad (complicaciones sobre 8 Gy). La vía óptica posterior tiene una sensibilidad similar al nervio óptico y quiasma, con potenciales lesiones apareciendo sobre los 8 Gy. Hay consenso en diferentes estudios de que la integración de la tractografía en la planificación permite disminuir significativamente la dosis recibida por los tractos estudiados sin comprometer la cobertura y dosis en target, y un trabajo muestra mejor resultado clínico al incluir tractografía de la vía motora y fascículo arcuato en la planificación.
Study of Temperature Gradients in Concrete Products in the Process of their Heat Moisture Treatment
Authors: Подвальный С.Л. , Усачев А.М. , Васильев Е.М.
Published: December 2023

Постановка задачи. Работа посвящена проблеме совершенствования технологического процесса производства бетонных изделий, в частности улучшению показателей этапа их тепловлажностной обработки. В качестве таких показателей выбраны пространственный и временной градиенты температуры в толще бетонного изделия, превышение которыми максимально допустимых для данного типа бетона значений отрицательно сказывается на прочности изделия. С другой стороны, паровлажностная обработки изделий с заведомо низкими значениями этих градиентов приводит к увеличению времени рассматриваемого этапа технологического процесса, т. е. к снижению производительности линии. В связи с этим поставлена задача количественной оценки температурных градиентов в сечениях бетонных изделий в процессе их тепловлажностной обработки путем использования соответствующей математической модели. Результаты. В результате исследований, проведенных на модели температурных полей в наиболее длительном режиме — режиме охлаждения, показана существенная неравномерность распределения температуры на границах сред «бетон — воздух», выявлены критические зоны этих полей в сечениях изделий и временные интервалы их существования. Выводы. Сделан и подтвержден вывод о целесообразности снижения температуры в камере по экспоненциальному закону и о необходимости контроля ее градиентов в критических сечениях изделий.

Statement of the problem. The work is devoted to the problem of improving the technological process of production of concrete products, in particular, improving the performance of the stage of their heat and moisture treatment. As such indicators, the spatial and temporal temperature gradients in the thickness of the concrete product are chosen, the excess of which exceeds the maximum allowable values for this type of concrete and adversely affects the strength of the product. On the other hand, steam-moisture treatment of products with obviously low values of these gradients leads to an increase in the time of the considered stage of the technological process, i. e. to reduce line performance. In this regard, the task was set to quantify the temperature gradients in the sections of concrete products in the process of their heat and moisture treatment by using the appropriate mathematical model. Results. As a result of studies carried out on the model of temperature fields in the longest mode — cooling mode, a significant uneven distribution of temperature at the boundaries of the «concrete-air» media was shown and critical zones of these fields in the sections of products and time intervals of their existence were identified. Conclusions. A conclusion was made and confirmed on the expediency of reducing the temperature in the chamber according to the exponential law and on the need to control its gradients in the critical sections of products.

Проведенный вычислительный эксперимент по математической модели распределения температурного поля позволил определить соблюдение температурного режима вулканизации материала защитного покрытия по всему объему вулканизата при определенных граничных условиях.

Statement of the problem. The process of vulcanization of the material of the protective coating of pipe metal based on low molecular weight oligodiene is possible only when creating and maintaining the specified temperature conditions in terms of the volume of vulcanizate. To study the regularities of the distribution of temperature fields in the vulcanized coating and to ensure the necessary temperature conditions of heat treatment, taking into account the influence of external influences, it became necessary to develop a mathematical model of the distribution of the temperature field in the protective coating material during its heat treatment using induction heating. Results. A mathematical model of the distribution of the temperature field in the vulcanized coating of pipe metal based on low molecular weight oligodiene has been developed. Conclusions. The conducted computational experiment using a mathematical model of the distribution of the temperature field made it possible to determine compliance with the temperature regime of vulcanization of the protective coating material over the entire volume of vulcanizate under certain boundary conditions.

Поражения ЯК в основном концентрируются на слизистой оболочке прямой и толстой кишки и подслизистой оболочке. Для пациентов с ЯК легкой и средней степени тяжести лучшее фармакологическое лечение включает глюкокортикоиды, иммунодепрессанты, антибиотики и биологические препараты, но длительное применение может иметь серьезные токсические побочные эффекты. Флавоноидные растительные натуральные продукты достигли замечательной эффективности при лечении язвенного колита. Фармакологические механизмы связаны с противовоспалительным действием, стимулированием заживления слизистой оболочки, поддержанием иммунного гомеостаза кишечника и регуляцией кишечной флоры. В этой статье мы обобщаем флавоноидные компоненты противоязвенного колита и их механизмы, о которых сообщалось за последние 10 лет, чтобы обеспечить основу для рационального клинического использования и разработки новых препаратов против язвенного колита.

Introducción: Las enfermedades prevalentes en adultos mayores son las enfermedades cardiovasculares, respiratorias, neurológicas y músculo esquelético. El objetivo fue determinar las enfermedades prevalentes en adultos mayores en la comunidad de Combuyo. Metodología: El estudio corresponde a un enfoque cuantitativo, descriptivo, transversal, observacional, prospectivo, la población de estudio fue de 41 adultos mayores. Los criterios de inclusión fueron personas mayores de 59 años con residencia >6 meses, la recolección de datos fue a través de un cuestionario de 8 preguntas cerradas de selección múltiple, posterior al consentimiento de adultos mayores, la base de datos se realizó en Excel, el análisis fue a través de un análisis de frecuencia. Resultados: la edad de mayor prevalencia fue de 60 a 65 años (49 %), población femenina (56 %), la patología cardiovascular más prevalente es la hipertensión arterial 29,2 %; diabetes 9,8 % artritis reumatoidea 26,8 %, y 4,9 % trastorno del sueño. Discusión: Por lo tanto, los hallazgos son similares a estudios realizados en distintos países de Latinoamérica, evidenciando leve discrepancia; estas patologías identificadas se convierte en un factor de riesgo para el desarrollo de otro tipo de enfermedades; es así que los hábitos y estilos de vida de los adultos mayores son elementos esenciales en la prevención de enfermedades o en el manejo de enfermedades existentes; por ese motivo estamos frente a desafíos que deben de considerarse en la política de salud  y seguir promoviendo nuevas recomendaciones y respuestas dirigidas a cada población, en función a estudios comunitarios, para soluciones concretas.

Published: December 2023

La computación del ADN es una forma de computación que usa moléculas de ADN y moléculas biológicas en lugar de las tecnologías informáticas tradicionales basadas en silicio, una de las razones por las que empezó a ser interesante estudiar la computación del ADN es que un sólo gramo de ADN con un volumen de 1 cm3 puede contener tanta información como un billón de discos compactos, aproximadamente 750 terabytes. Otra característica importante de los procesos del ADN es la capacidad de realizar muchas operaciones en pararelo, lo que es posible gracias a la capacidad de replicación del ADN.Richard Feynman introdujo por primera vez el cálculo molecular a principios de 1960, pero fue hasta 1994 cuando Leonard Adleman, de la Universidad del Sur de California, demostró un uso del ADN para resolver el problema Hamiltoniano de 7 puntos. Después de su trabajo, diversos investigadores han encontrado nuevas aplicaciones para la computación del ADN, y en diversas áreas se ha descubierto la importancia de llevar los cálculos a nivel molecular. El objetivo del artículo es mostrar cómo se utiliza la teoría de campos finitos para construir códigos cíclicos que permiten modelar la estructura del ADN. Esta modelación es importante porque se conocen algoritmos basados en ADN que permiten resolver, mediante procesos químicos, algunos problemas clásicos como el del árbol de expansión mínima y el del coloreado de una gráfica con tres colores. Actualmente, se están desarrollando simulaciones de estos algoritmos mediante computadoras.

Biomaterials are substances that have been engineered to interact with biological systems for a medical purpose, either a therapeutic or diagnostic one. Biomaterials have a rich history of evolution, as they have continuously transformed from simple inert substances to complex, interactive materials, designed to communicate with biological systems and promote tissue regeneration and healing. Titanium, due to its excellent biocompatibility, corrosion resistance, and mechanical properties, has established its place as one of the most used biomaterials, particularly in orthopedics and dental applications. This article provides an overview of titanium as a biomaterial, highlighting its properties, applications, and recent advancements.

This research addresses the metallurgical and mechanical response during the annealing of Ti6Al4V parts fabricated by selective laser melting. The as-manufactured Ti6Al4V exhibited a very fine α´ martensitic structure with low ductility of less than 10%. It was observed that the fine α´ martensitic structure transformed into two phases of α and β by applying heat treatments at 850 and 1020 °C followed by furnace cooling. The experimental results demonstrated that 850°C/2h/FC heat treatment has optimum mechanical performance in terms of tensile strength and ductility.
