Authors: Tjahjana R. Heru
Published: May 2022

AbstractIn this paper, uncoupled two agents modeling is proposed using an optimal bilinear control approach. The model is proposed using assumptions: an absence of the multi agent leader, each agent cannot control the others, each agent never collides with the others, and each agent has the same properties. The special functional cost consisting of a repellent cost is considered. The Pontryagin Maximum Principle is used to determine the optimal path for each agent. After control and optimal path for each agent are obtained some of the simulation results are exposed in this paper.Keywords: uncoupled agent; modeling; bilinear system. AbstrakDalam penelitian ini, pemodelan dua agen yang tidak berpasangan disajikan dengan pendekatan kontrol optimal bilinear. Model yang diusulkan dalam paper ini ditulis dengan asumsi: tidak adanya pemimpin dalam sistem multi agen, setiap agen tidak dapat mengendalikan atau mempengaruhi agen yang lain, setiap agen tiak boleh bertabrakan satu sama lain, dan para agen mempunyai sifat-sifat yang identik. Fungsional biaya khusus yang membuat para agen tidak bertabrakan dipertimbangkan dalam penulisan paper ini. Prinsip maksimum Pontryagin digunakan dalam penentuan lintasan optimal dari para agen.  Beberapa hasil simulasi disajikan dalam paper ini.Kata Kunci: agen tak berpasangan; pemodelan; sistem bilinear.
A Property of Lattices of Sublattices Closed Under Taking Relative Complements and Its Connection to 2-Distributivity
Authors: Czédli Gábor
Published: May 2022

For a lattice L of finite length n, let RCSub(L) be the collection consisting of the empty set and those sublattices of L that are closed under taking relative complements. That is, a subset X of L belongs to RCSub(L) if and only if X is join-closed, meet-closed, and whenever {a, x, b} ⊆ S, y ∈ L, x ∧ y = a, and x ∨ y = b, then y ∈ S. We prove that (1) the poset RCSub(L) with respect to set inclusion is lattice of length n + 1, (2) if RCSub(L) is a ranked lattice and L is modular, then L is 2-distributive in András P. Huhn’s sense, and (3) if L is distributive, then RCSub(L) is a ranked lattice.
Efecto de la microestructura y los tratamientos térmicos sobre aleaciones hipereutécticas de Al-Si Solidificadas Rápidamente

Published: May 2022

RESUMEN La aleación eutéctica AA-4032 es ampliamente utilizada en pistones de motores de combustión interna dada su buena combinación de propiedades a temperaturas intermedias. Una mejora importante en las propiedades podría obtenerse mediante el aumento de la fracción de Si en aleaciones Solidificadas Rápidamente (SR) y posteriormente compactadas, evitando así la formación grandes placas de Si características de las aleaciones hipereutécticas. Sin embargo, si bien se es conocido su comportamiento mecánico, el estudio del comportamiento frente a la corrosión aún es incompleto. En este trabajo se estudiaron dos aleaciones hipereutécticas, con 20%m y 30%m de Si (composición nominal), obtenidas por SR y compactación por Extrusión en Caliente, en comparación con la aleación eutéctica AA-4032 (12%m de Si). Posteriormente, se realizaron tratamientos térmicos de Solubilización (1h-530ºC) y un Envejecimiento artificial (170ºC-10hs). La caracterización microestructural se realizó mediante Difracción de Rayos X (DRX) y Microscopía Electrónica de Barrido (MEB) y Espectroscopia Dispersiva en rayos X (EDS). Se analizó el comportamiento frente a la corrosión por medio de ensayos de polarización potenciodinámica en solución 0.1M y 1M NaCl a temperatura ambiente y pH neutro. Las superficies de las probetas ensayadas fueron caracterizadas morfológicamente mediante MEB y EDS. Se discute la influencia del contenido de Si en las aleaciones y su distribución en la microestructura sobre la forma de las curvas de polarización y sus parámetros característicos. Microestructuralmente se observó que el proceso de SR evitó la formación de las placas de Si primario, mientras que los tratamientos térmicos promovieron, entre otras cosas, la esferoidización de las partículas intermetálicas. Por otro lado, los ensayos de corrosión mostraron que: el potencial de picado de las aleaciones resultó ser independiente del contenido de Si, que las muestras solubilizadas presentaron la menor corriente de pasivación y que en todos los casos se produjo la disolución preferencial del aluminio.
Aerodinâmica de autos para o ensino médio na abordagem dos Três Momentos Pedagógicos
Authors: Vieira Crislan Alves , Pires M.O.C.
Published: May 2022

The topic of fluid dynamics is rarely addressed fully in high school classes. The absence of this subject in the school year, the extensive content and the lack of connections with the student’s reality are features that put aside hydrodynamics and aerodynamics discussion in the classroom. However, the presence of these areas is recognized in the daily life. For this purpose, examples can be cited from the support of aircraft to the pressure of water coming out of the tap. This proposal attempts to include a routine subject for students. The automotive aerodynamics do not surprise the student and, at the same time, it allows to systematize the formal teaching of the phenomena of fluid physics and take the sustentability assumption in acount. The proposal constitutes a class sequence aided by a low-cost experiment and a simulator of a wind tunnel. For the elaboration of this proposal, the Freirean teaching methodology known as the Three Pedagogical Moments (3MP) was used.

Esses valores foram comparados com outros adotados na literatura, mostrando boa concordância.
Pequena introdução a QFT
Authors: Thibes Ronaldo
Published: May 2022

Abstract We deliver a motivational introduction to quantum field theory, aimed at curious students interested in that important and broad realm of contemporary physics. Assuming knowledge of the well-known quantum mechanics and special relativity fundamentals, we briefly review and discourse about its main ideas, methods and precepts, looking forward a generalization to quantum field theory. We show how the apparent incompatibility between relativity and quantum mechanics, present in some initial textbooks on the subject, may be elucidated and cleared out through the field concept, allowing for a consistent description of elementary particles interactions in the domains of validity intersection for those two theories. We explain in a clear and simple way what came to be known in the literature as second quantization. The text, eminently didactic and motivational, is accessible to final year undergraduate or starting post graduate students with a good prior knowledge of special relativity and quantum mechanics.

Recomenda-se a implementação de ações e estratégias, com destaque para a educação em saúde, a fim de prevenir casos de intoxicação exógena.
International Political Economy and Sustainable Finance: Assessing the EU’s Green Deal and UNCTAD’s Green New Deal
Authors: Jäger Johannes
Published: May 2022

Abstract Sustainable green finance is often promoted as an innovative tool to deal with environmental problems. This paper assesses policy proposals at the level of the EU and UNCTAD’s Green New Deal, specifically regarding its suggestions in the field of sustainable finance. It provides a theoretical framework in the tradition of critical political economy and combines a global perspective with regulation theory in order to assess different strategies in the area of sustainable finance. The respective proposals and initiatives can be considered as possible blueprints for hegemonic strategies within different contexts. However, the analysis suggests both proposals, although substantially different and representing different entities in the international political economy, fail to provide a systematic answer to the problems of a highly unequal over-use of natural and environmental resources at a global level.

Published: May 2022

Abstract Tick-borne pathogens belong to one of the two main groups of occupational biohazards, and occupational exposure to such agents puts soldiers at risk of zoonotic infections, such as those caused by rickettsiae. There are few studies on acarological fauna and occupational risk in military areas in Brazil. Thus, the present study aimed to analyze the diversity of ticks present in the military training areas of municipalities in the Southeast Region of Brazil. The ticks were collected from the selected areas using the dragging and flagging techniques as well as by visual detection on the operators’ clothing, and environmental information was also recorded. A total of ten species were collected from the 66 surveyed areas, belonging to five genera and nine species: Amblyomma sculptum, Amblyomma dubitatum, Amblyomma brasiliense, Amblyomma longirostre, Amblyomma aureolatum, Dermacentor nitens, Rhipicephalus spp., Ixodes spp. and Haemaphysalis spp. The frequent presence of tick species in military training areas along with traces and sightings of wild animals, most commonly capybaras (Hydrochoerus hydrochaeris), in most of the studied areas, indicates high levels of exposure of the military to tick vectors of spotted fever group rickettsiae and the possible occurrence of infections among the troops.

A Economia Solidária pode ser entendida como experiências econômicas fundamentadas em valores diferenciados e praticadas a partir da autogestão. Este trabalho teve o objetivo entender como a educação pode fortalecer a Economia Solidária, buscando trazer, inclusive, algumas das temáticas educativas demandadas pelos trabalhadores e trabalhadoras da ES. Inicialmente dialogou-se sobre o papel da Educação no Modo de Produção Capitalista, a fim de entendê-la, também, enquanto instrumento de transformação. Foi trazido para o debate as possibilidades de espaços de educação (educação formal, informal e não-formal) com vistas na defesa da educação não-formal como o espaço pedagógico mais apropriado para a ES, aliada a prática da educação popular. Por fim, uma pesquisa exploratória, descritiva e de caráter qualitativo, realizada com os coordenadores do Fórum de Economia Solidária de Guarabira e Região, através de um grupo focal e entrevistas semiestruturadas, possibilitou constatar diversas demandas formativas, relacionadas a gestão dos empreendimentos, aspectos organizacionais, mas, principalmente, sobre os princípios e valores que norteiam a ES. Sugere-se o desenvolvimento de novas pesquisas direcionadas a essas demandas e preocupadas com a adaptação do conhecimento científico ao perfil do público direcionado.

Nuclear accent placement in broad focus intransitives in native and non-native English: an investigation of syntactic and pragmatic factors
Authors: Landblom Stephanie A , Ionin Tania
Published: May 2022

Simple broad focus intransitives in English have been observed to occur with variable nuclear accent (NA) placement on either the subject or verb. This variability can be difficult to acquire in a second language (L2), especially when the speaker’s first language (L1), such as Spanish, has less flexible NA placement. Learners tend to transfer L1 intonational patterns into their L2, but there is still more to understand about the learning trajectory. Furthermore, the factors driving the NA placement alternation in intransitives are not yet fully understood for L1 speakers; there is a debate about whether NA placement is driven by syntactic factors, pragmatic factors, or a combination of the two. The study reported in this paper used an oral production task to elicit broad focus intransitives from both L1 English speakers and L1 Spanish L2 English learners. Verb type and expectedness were crossed in stimuli construction in order to test the effects of both syntactic and pragmatic factors on NA placement for both speaker groups. The results indicate that L1 speakers are most likely to produce NA on the subject of expected unaccusative verbs, and to produce NA on the verb in all other conditions. L2 speakers show a stronger preference for utterance-final NA placement on the verb, which is likely transferred from the preferred pattern of their L1. At the same time, L2 learners of higher proficiency do show evidence of acquiring the target NA placement pattern.

On cooling rate of metal melt in steel-pouring ladle and tundish during steel continuous casting
Authors: Vil’danov S. K. , Bondarev D. Yu.
Published: May 2022

Correlation analysis methods were used to study the thermal state of liquid metal at the stage of steel continuous casting under the assumption that measurable objects are random variables. Thermal state of the metal melt is characterized by the values ​​of the metal temperature Tn at this stage and duration of the stages τn and it is described by an integral indicator – cooling rate Wn . Cooling rate is the ratio of temperature difference of the liquid metal at the beginning and end of the stage to the duration of this stage. The metal cooling rates were calculated at various stages of steel continuous casting. The first stage includes the period from the completion of metal processing at a unit of complex steel processing to the start of vacuum treatment. The second stage includes the period from the start of vacuum treatment to its completion. The third stage includes the period from the end of vacuum treatment to the first temperature measurement in the tundish. And further, there are periods of successive temperature measurements in the tundish. It has been established that the metal cooling rates vary considerably depending on the technological stages. Absolute values ​​of the cooling rate differ by more than an order of magnitude. The minimum metal cooling rate is fixed in the tundish. Its value is 0.09  °С/min. The maximum cooling rate of the metal was revealed when the metal was tapped from the steel-pouring ladle into the tundish, while the cooling rate was 1.43  °C/min. The main factors influencing the metal cooling rate were revealed. These factors include the presence of a layer of liquid slag on the metal melt surface in the steel-pouring ladle after out-of-furnace processing. These factors include initial temperature of the liquid metal after completion of treatment at the unit of complex steel processing, the liquid metal temperature after completion of vacuum treatment, presence of oxide solution formed by slag-forming mixtures on the liquid metal surface, presence and effectiveness of heat-insulating mixtures, as well as the heat-insulating characteristics of refractory linings. During vacuum treatment, the metal cooling rate was essentially determined by convective energy losses and energy losses for heating the inert gas. After the stage of vacuum treatment, the cooling rate is significantly reduced due to the use of heat-insulating mixtures. The highest metal cooling rate is set when it passes through the steel outlet channel and the metal protection pipe when filling the tundish. The lowest metal cooling rate is typical when it is in the tundish, due to the presence of a porous plastic refractory layer with low thermal conductivity.
Pendulum surface plastic deformation of cylindrical blanks
Authors: Zaides S. A. , Quan Ho Minh
Published: May 2022

The article discusses the features of kinematics of the working tool in form of circular sector during hardening by pendulum surface plastic deformation (SPD), which is carried out due to two successive processes – rolling and sliding in the contact zone of the deforming element with the blank. Forecasting of the possibility of its application for finishing and hardening processing of cylindrical parts such as shafts and axles is presented; the kinematic parameters of the pendulum SPD process in a rectangular coordinate system are described. Based on analysis of the components of motion types (rotational, translational, oscillatory) of the blank and tool, functions of the trajectory length, magnitude of the resulting velocity and acceleration were determined, which make it possible to control the technological parameters and modes of the pendulum SPD process. Reliability of the kinematic analysis is confirmed by the results of simulation with ANSYS  19.1 computer program. The results of dynamic modeling showed that under the same hardening conditions with a stationary position of the working tool and its opposite rotation with the blank, the intensity of temporary stresses increases by 10 % and 17 %, respectively, compared to the rolling scheme. With pendulum SPD, the intensity of temporary stresses increases sharply and reaches a maximum value (485 MPa), the distribution of which is uniform in comparison with other methods. In addition, regularity of the intensity distribution of temporary stresses over the cylinder depth is shown, where it is clear that in the case of SPD by sliding, the depth of plastic deformation h has a higher value compared to the SPD by rolling (by 1.5 – 2.3 times). Under the same hardening conditions, the highest value of the depth of the hardened zones is obtained with pendulum SPD (h = 2.8 mm), which leads to changes in the physical, mechanical and operational properties of the blank deeper surface layer.

Disruptions in Translational Intertextuality across Multilingual Translations of a Historical Inscription
Authors: KAHYAOĞLU Serhat , YILDIZ Mehmet
Published: May 2022

This is the first research study to investigate translational intertextuality across multilingual translations of a historical inscription through retranslation and relay translation. It aims to offer a translational chain by linking the studied translations that involve different translational strategies and reveals intra- and multi-lingual alterations within the collection of the analyzed works. The corpus of the study consists of six academic works – on the interlingual translations of a historical inscription in Alanya, Türkiye – in five different languages, including the source language. To analyze the corpus, qualitative content analysis and purposeful sampling are applied. It is revealed that the translations tend to change their textuality through semantic alterations and application of translational phenomena, and thanks to the alterations, it is seen that the source text evolved through translations. It is suggested that translational intertextuality has a crucial role in the creation of new texts in a target language based on a translation, and the studied corpus illustrated that any disruptions in translational intertextuality affect the other rings of the translation chain, directly or indirectly helping to disseminate false knowledge or/and foreignizing the resultant text for the target audience. Moreover, it is highlighted that an ulterior translation can be affected by these disruptions; therefore, the disrupted prospective translational intertextuality could influence the intertextual ties across disciplines established by translations.

Türk dış politikası Lozan Antlaşması ile birlikte bir yandan Osmanlı Devleti’nden devraldığı mirasın yıllar içerisinde birikmiş sorunlarını çözmeye çalışırken bir yandan da bölgesel dostluk ve güvenlik ilişkilerini geliştirmeye çalışmıştır. Bu sürecin en önemli belirleyicilerinin başında ise Birinci Dünya Savaşı’nın sonuçlarının yarattığı siyasal ve askeri gelişmeler gelmiştir. Şüphesiz ki bu durum İkinci Dünya Savaşı’nın da habercisi olmuştur. Türkiye Cumhuriyeti bölgesinin hızla savaşa sürüklenen bu gerçekliği içerisinde bir yandan uluslararası ittifaklara dâhil olurken bir yandan da bölgesel güvenlik antlaşmaları yapmıştır. Ancak bu durum sanıldığı kadar kolay olmamıştır. Nitekim sınır komşuları ile tarihsel süreçten gelen sorunların aşılması gerekmektedir. Ki bu noktada Yunanistan önemli bir yere sahiptir. Ancak her iki ülkenin karar alıcıların pragmatik ve akılcı siyaseti sorunların çözümünü hızlandırmış ya da bir süreliğine dondurmuştur.
Bu çalışmada Balkan Antantına giden süreçte ve hemen sonrasında Yunanistan iç politik gelişmelerindeki muhalif yaklaşımlar, Atina Türk elçiliği raporlarından hareketle incelenmeye çalışılmıştır.

Published: May 2022

Introdução: O diagnóstico do hiperparatireoidismo primário (HPTP) melhorou nos últimos anos, identificando-se a forma assintomática com hipercalcemia leve e a normocalcêmica, com níveis normais de cálcio. Objetivo: identificar o perfil epidemiológico e estabelecer a prevalência de doença óssea e litíase renal em pacientes com HPTP atendidos no ambulatório de um centro de atendimento terciário à saúde no estado de São Paulo, Brasil. Métodos: Análise retrospectiva dos prontuários de pacientes atendidos no ambulatório no período de julho de 2015 a junho de 2016 com diagnóstico de HPTP (44 pacientes). Considerando a presença de hipercalcemia, foram caracterizados dois grupos de pacientes: com hipercalcemia (n=36) e com normocalcemia (n=8). Os exames laboratoriais e de imagem foram avaliados. Resultados: O grupo hipercalcêmico mostrou média de idade superior à do normocalcêmico e menor função renal. A diminuição da massa óssea esteve presente em ambos os grupos hipercalcêmico e normocalcêmico com prevalência de 82% e 62,5% e de osteoporose de 57,6% e 37,5%, respectivamente. A litíase renal, analisada por ultrassom renal, foi identificada em 42% e do grupo hipercalcêmico e em 66,6% do grupo normocalcêmico. Conclusão: a osteoporose e a litíase renal são frequentes no HPTP, tanto na forma hipercalcêmica como normocalcêmica. Abordagem adequada dos portadores dessa morbidade pode prevenir complicações ósseas e renais.
Cognitive Predictors of Academic Success: How Do the General Patterns Work in the Early Stages of Education?
Authors: Dvoinin A.M. , Trotskaya E.S.
Published: May 2022

The article provides an overview of modern works devoted to the study of cognitive predictors of academic success. The general patterns of forecasting are revealed: the most powerful and universal predictor of academic success at different stages of school education is psychometric intelligence; creativity is less significant and rather unstable. It is argued that these patterns are poorly traced at the level of preschool education. Particular cognitive functions are significant for predicting the future educational achievements of preschoolers: information processing speed, visual perception (in combination with motor functions), short-term memory, and attention. Spatial abilities have a certain prognostic potential, though reasoning in preschoolers is not a strong predictor of academic success; executive functions have the greatest predictive power. It is noted that the general patterns in predicting the academic success of students can be traced in elementary school: the predictive potentials of psychometric intelligence are revealed, the power of individual cognitive abilities (in particular, spatial abilities) increases, the contribution of executive functions to the prediction decreases. The general tendency for non-cognitive factors (educational motivation, some personality traits) to increase with age also begins to appear in elementary school.

Published: May 2022

Choux pastry kering substitusi konsentrat protein ikan gabus mempunyai kandungan protein dan lemak yang cukup tinggi sehingga mendorong penurunan mutu fisik dan kimiawi selama penyimpanan. Pengemasan yang tepat pada choux pastry ini perlu dilakukan untuk mencegah terjadinya penurunan mutu produk. Tujuan penelitian ini untuk mengukur pengaruh kemasan yang digunakan terhadap mutu choux pastry kering dengan susbtitusi konsentrat protein ikan gabus yang disimpan pada suhu 26-29oC selama 56 hari. Penelitian berupa eksperimen dengan desain rancangan acak lengkap (RAL) dua faktor perlakuan yaitu jenis kemasan (aluminium foil dan plastik polipropilena) serta waktu penyimpanan (14, 28, 42, dan 56 hari). Penyimpanan dilakukan menggunakan metode ESS (Extended Storage Studies). Data dianalisis menggunakan uji statistik oneway anova dengan derajat kepercayaan 95%. Apabila ada perbedaan nyata dilanjutkan pengujian dengan DMRT pada taraf α 5%. Choux pastry kering dengan pengemasan aluminium foil dan plastik polipropilena selama penyimpanan 56 hari tidak berbeda nyata dari atribut rasa, warna, dan aroma akan tetapi berbeda nyata dari segi tekstur. Terjadi peningkatan nilai asam lemak bebas, angka peroksida, dan kadar air pada choux pastry kering seiring semakin lama waktu penyimpanan. Kemasan aluminium foil lebih baik digunakan sebagai pengemas choux pastry kering dibandingkan dengan kemasan plastik polipropilena dilihat dari tekstur, asam lemak bebas, kadar air, dan angka peroksida choux pastry kering selama penyimpanan

Ikan patin (Pangasius hypophthalmus) adalah salah satu ikan air tawar dengan nilai ekonomi tinggi. Pengasapan ikan patin di Kecamatan XIII Koto Kampar menghasilkan lemak isi perut. Mayoritas minyak dari limbah ikan patin merupakan lemak perut. Tingginya rendemen minyak mendorong pemanfaatan sebagai produk pangan, seperti mayones. Penelitian ini bertujuan untuk meningkatkan kualitas dari minyak ikan patin dan uji sensori mayones. Minyak diekstraksi dari pemanasan lemak perut ikan patin di suhu 65°C selama 7 jam dengan pemurnian magnesium silikat (magnesol) konsentrasi (1, 2, 3, 4, dan 5%) dalam mengadsorpsi warna dan aroma dari minyak ikan patin. Hasil sidik ragam memperlihatkan bahwa konsentrasi magnesol 3% berpengaruh nyata dalam menurunkan karakteristik minyak antara lain viskositas, kadar ALB, bilangan peroksida, dan bilangan TBA dari 61,83 menjadi 37,00 cP; 0,70 menjadi 0,15%, 3,03 menjadi 1,94 meq.O2.kg-1, dan 9,58 menjadi 6,79 mg.mal.kg-1. Mayones dengan minyak murni konsentrasi magnesol 3% berwarna kuning cerah, tidak beraroma amis, bertekstur agak kental, dan berasa minyak ikan patin. Secara keseluruhan, mayones agak disukai oleh panelis berdasarkan penilaian hedonik.

Active film adalah salah satu tren dunia untuk kemasan makanan. Active film seringkali mengandung bahan aktif antimikroba, antioksidan, penangkap oksigen, dan sawar UV untuk membantu menjaga kesegaran makanan. Kitosan merupakan salah satu bahan aktif yang dapat dimanfaatkan sebagai active film. Kitosan memiliki aktivitas antimikroba yang baik tetapi hanya dapat digunakan pada pH rendah. Oleh karena itu, kitooligosakarida/chito-oligosaccharide (COS) yang merupakan oligomer kitosan dengan kelarutan lebih baik berpotensi sebagai alternatif. Penelitian ini bertujuan untuk menentukan karakter COS yang dihasilkan dengan metode depolimerisasi mikrogelombang, ultrasuara, dan kombinasi mikrogelombang-ultrasuara serta menentukan sifat mekanis active film terbaik dari COS yang diproduksi dengan kosentrasi 1,5% dan 2%. COS yang diperoleh berwarna kekuningan dengan nilai viskositas 12-17 cP dan bobot molekul berkisar dari 22,1-29,3 kDa yang nilainya lebih kecil daripada kitosan (>50 kDa). COS yang diproduksi menunjukkan aktivitas antimikroba pada bakteri B. subtilis, S. aureus, dan E. coli. Hasil penelitian menunjukkan bahwa terdapat berat molekul COS yang optimal yang dapat dimanfaatkan sebagai bahan film. COS dengan berat molekul rendah cenderung memiliki sifat mekanis film yang buruk karena ikatan antar-molekulnya lemah. Secara keseluruhan, sifat mekanis terbaik film dicapai pada film COS ultrasuara konsentrasi 2%. Film tersebut memiliki ketebalan 0,25 mm nilai WVTR terendah pada 5,25 g/m2/hari, kekuatan tarik, dan elongasi berturut-turut 5,43 N/mm2 dan 76,7%. Warna film COS yang kekuningan cenderung menyerap sinar UV lebih baik dibandingkan dengan film kitosan.

Evolución del concepto de seguridad hemisférica a la luz de las nuevas amenazas.
Authors: Angel Alvarez Jaime Alberto
Published: May 2022

Después de la caída del bloque socialista y el fin de la Guerra Fría, el panorama de la política, de la economía y de la seguridad global ha cambiado de manera radical. En este artículo de investigación se analiza el papel de la seguridad nacional como concepto integral que debe responder a los múltiples y complejos desafíos de cada región del globo. Se halló que el fin del mundo bipolar significó cambio de escenarios en términos de seguridad internacional. El fin de la disputa entre el capitalismo y el comunismo, tras la aparición de una potencia hegemónica mundial y la inexistencia de un sistema de seguridad que respondiera al veloz cambio de la historia al que la humanidad estaba asistiendo, generaron la necesidad de redefinir las reglas de juego en el mundo en función de la posible existencia de armas de destrucción masiva y de múltiples conflictos regionales. Se concluye que el actual esquema de seguridad hemisférica tiende a colapsar ante la desatención de los países y la desarticulación de los esfuerzos por controlar situaciones apremiantes de seguridad.
El estado civil de “compañero permanente” en Colombia y la negativa de su reconocimiento en España.
Authors: Marín Ordóñez Jennifer Stella
Published: May 2022

El estado civil configura la existencia de derechos y obligaciones entre cónyuges, compañeros permanentes, padres e hijos. En las siguientes líneas se podrá apreciar de manera breve cómo ha sido reconocido el estado civil de compañero permanente por vía jurisprudencial en Colombia y todo ello basado en los presupuestos legales existentes; así como también se alcanza a dilucidar la normativa y doctrina española a efectos de demostrar que no existe un limitante para que se proceda con la regulación integral de las uniones de pareja estable y claro está para el reconocimiento de dichas uniones como estado civil.
