Authors: Usman Sriati , Budi Budi , Kamaruddin Abdul , Faradila Ayu
Published: August 2023

ABSTRACTThis research analyzes the implementation of the "bits and pieces" game on students' learning outcomes in writing English descriptive texts. A quasi-experimental design with Junior High School students as the population and a cluster random sampling technique used to draw the sample. Furthermore, two groups were administered pre- and post-test to collect the data. According to the data analysis, a noteworthy disparity existed in the post-test outcomes between the two groups. The experimental group had an average score of 86.60, whereas the control group had 62.43 score. By setting a significance level of 0.05 and degree of freedom (df) of 40 (21+21-2), the t-test demonstrated that the calculated t-value (6.487) surpassed the critical value (1.684), thereby indicating the acceptance of the research hypothesis. This implied that bits and pieces games have an effect on enhancing students’ learning outcomes. Therefore, the game can be a great contribution for English teachers in teaching English descriptive text, in terms of improving content, mechanics, organization, sentence structure, and grammar. ABSTRAKPenelitian ini menganalisis implementasi permainan bits dan pieces terhadap hasil belajar siswa dalam menulis teks deskriptif dalam bahasa Inggris.

Rasgos de la concepción de «antigüedad» de Jules Michelet contenidos en su «Introduction à l´histoire universelle»
Authors: Pérez-Medina Simón-Vladimir
Published: August 2023

El artículo busca exponer los principales rasgos de la concepción de antigüedad contenidos en la Introduction à l´histoire universelle creada por Jules Michelet en el siglo XIX, para lo cual se utiliza principalmente una metodología analítica aplicada al texto, complementada por una de carácter sistémico que permite ubicarla en el contexto de la época en que fue escrita. La búsqueda de aquel objetivo hizo posible que las siguientes páginas estén divididas en dos partes dedicadas, la primera, a establecer los aspectos básicos del autor y su obra; y la segunda, a señalar tres asuntos: primero, la noción de historia antigua contenida en aquella obra del sabio francés; segundo, la manera en que éste desarrolló sus ideas sobre cada pueblo tratado en sus líneas sobre la antigüedad; y tercero, las frecuentes alusiones a hechos de esta época contenidas en su explicación de las posteriores etapas de la historia universal.

The problem of solving a system of linear ordinary differential equations with constant coefficients is one of the most important problems in both the theory of ordinary differential equations and linear algebra. Therefore, on the one hand, new methods and algorithms are being developed for such systems, and on the other hand, existing methods and algorithms for solving such systems are being improved. One of the most well-known methods for solving a system of linear ordinary differential equations with constant coefficients is the method of reducing a system of linear equations to a single higher-order equation, which makes it possible to find solutions to the original system in the form of linear combinations of derivatives of only one unknown function.In this paper, we consider a refinement of the method for reducing a system of linear ordinary differential equations with constant coefficients to a single higher-order equation, which makes it possible to find a general solution to the original system; namely, we study the expressibility of all functions of the system of linear homogeneous differential equations with constant coefficients x^' (t)= A⋅x(t) in the form of linear combinations of derivatives of only one unknown function x_k (t), which is part of this system. For any matrix A, all of whose eigenvalues are not multiples, a new simple criterion for expressibility in terms of matrix ranks is formulated, and its correctness is proved. The result obtained can also be applied in the study of solutions of the system x^' (t)= A⋅x(t) for periodicity and in the study of linear systems for complete observability.

Published: August 2023

The relevance of the research topic is determined by the rapid development of technology, the variability of the external environment and the beginning of the third industrial revolution, which leads to instability, uncertainty and complexity of the modern world. It is noted that the existing production management tools do not meet new challenges, and that new management tools are needed to ensure the flexibility and effectiveness of production in a volatile environment. The article proposes the concept of creating intelligent control systems for industrial enterprises based on knowledge, fuzzy logic and intelligent information processing. An industrial enterprise is viewed as a complex system consisting of hierarchies of goals, decision making and business processes. A brief analysis of the main types of automated production management systems, such as ERP, APS, MES, SCADA and APCS is given. It is noted that in connection with the transition to industry 4.0, there is a need to create intelligent control systems (ICS) based on knowledge, fuzzy logic and intelligent information processing. It is proposed to develop existing automated control systems by creating built-in intelligent elements capable of automatically solving optimal control problems and influencing production by transferring control actions to the control system. The system is developed on the basis of mutually integrated standard automated control systems and the situational center of the enterprise. The implementation and use of ICS will increase the speed and efficiency of decision-making, allowing enterprises to better adapt to changes and optimize the use of resources.
H/D exchange studies of methane activation mechanisms in heterogeneous catalysis
Authors:   Institute of High Temperature Electrochemistry of the Ural Branch of the Russian Academy of Sciences, Zakharov Dmitriy M.
Published: August 2023

The development of technologies for the efficient conversion of methane and other light hydrocarbons is becoming vital to the chemical industry. The main technologies for methane conversion are based on solid and liquid catalysts such as metals, oxides and oxide-supported metals. Methane is a highly stable molecule, and the analysis of the catalytic activity of materials with respect to the C-H bond cleavage in methane is of paramount importance for the development of novel methane conversion catalysts. One of the most promising methods for studying methane activation over a catalyst is H/D isotope exchange between the gas and condensed phases. The method provides reliable in situ information on the cleavage of chemical bonds in molecules and allows researchers to elucidate the elementary steps of catalytic methane activation and the stable intermediates involved in the activation process. This paper focuses on the critical analysis of H/D isotope exchange studies of the methane activation mechanism over various metals, oxides, composites, and other catalysts, from the earlier studies to the recent advances in the field. The existing theoretical and experimental approaches to study the H/D exchange between methane and a catalyst are discussed in the paper. A critical analysis of the structure-composition-catalytic activity relationships of the catalysts with respect to methane activation is provided.

Published: August 2023

Perovskite or perovskite-related structural materials are widely studied for their many functional properties. They can be used as components of energy sources such as solid oxide fuel cells. Along with classical perovskites, layered perovskites can also carry out high-temperature proton transport and are promising materials for use in electrochemical power engineering. In this paper, the possibility of heterovalent and isovalent doping of La and Sc sublattices of bilayer perovskite SrLa2Sc2O7 was made for the first time. It was shown that electrical conductivity increases in the row of bilayer perovskites SrLa2ScInO7 – SrLa2Sc2O7 – BaLa2In2O7 – BaNd2In2O7.
Dagkirurgi for økonomien sin del
Authors: Dahl Miriam , Boge Jeanne Helene , Eide Petrin Hege , Horne Rolf
Published: August 2023

I 2020 ble bortimot 70% av alle kirurgiske inngrep i Norge utført som dagkirurgi. Ved dagkirurgi kommer pasienten til sykehuset og reiser hjem samme dag, og pasienten er sin egen sykepleier før og etter operasjonen.
Denne artikkelen handler om hvordan den norske regjeringen har posisjonert seg til dagkirurgi. Artikkelen er basert på analyser av regjeringsdokumenter om dagkirurgi fra perioden 1995-2020. Den franske sosiologen Pierre Bourdieu sin praktikkteori og praxeologiske konstruksjoner av regjeringsdokumentenes habitus, er brukt som analytiske verktøy.
Analysene viser at den dominerende argumentasjonen i regjeringsdokumentene handler om at dagkirurgi er kostnads- og ressursbesparende. Argumenter som at dagkirurgi kan være et gode for pasientene, benyttes for å legitimere gjeldende praksis.
Regjeringens argumentasjon for mer dagkirurgi er i samsvar med selvhjelpsideologien som oppstod i sykepleiefaget på 1960-tallet og med LEON-prinsippet som oppstod på 1970-tallet, om omsorg på lavest mulig omsorgsnivå.  Argumentasjonen samsvarer også med New Public Management-ideologien som fikk innpass i offentlig sektor i Norge på 1990-tallet.
A CONQUISTA DA UNIVERSIDADE: OCUPAÇÃO INDÍGENA EM TORNO DE UM TERRITÓRIO EM DISPUTA
Authors: Machado Tadeu
Published: August 2023

O presente artigo se propõe fazer uma análise sobre a presença de estudantes indígenas nas universidades. Para a construção do presente trabalho foi utilizada pesquisa bibliográfica, além de recorrer aos dados da Sinopse do INEP, como também ao envolvimento do pesquisador com os povos indígenas do Oiapoque, município do Estado do Amapá. Consideramos que a presença de estudantes indígenas nas universidades é um fato relativamente novo na história das universidades brasileiras, e que, portanto, merece de uma atenção minuciosa para sua análise, uma vez que faz parte de uma conjuntura que necessita de uma reflexão em torno das políticas reivindicadas pelos povos ameríndios e que continuam na pauta indígena como uma ação necessária. Nos últimos 15 anos tem-se acentuado a presença de estudantes indígenas nas universidades brasileiras. Mesmo entendendo que isso representa a força da mobilização do movimento indígena, compreendemos que ainda precisamos avançar para que a universidade seja conquistada em sua totalidade pelos indígenas e se torne também um território seu.
Effects of Placebo on the Management of Chronic Low Back Pain
Authors: Ambrožič Mark , Manojlović Denisa
Published: August 2023

A placebo is the result of an individual's neurobiological and psychophysiological responses to a substance or therapy that has no therapeutic effect but produces an improvement. Previously, some commonly prescribed therapies for chronic low back pain have been shown to be no better than placebo or only marginally more effective. The aim of this systematic literature review was therefore to examine the effects of placebo on the management of chronic low back pain. A review of the literature available in the PubMed, CINAHL and PEDro databases from 2012 to 2023 provided a set of nine studies. The results of the included studies suggest that placebo is part of any therapy in the form of various interacting biopsychosocial factors. Placebo has been shown to have the greatest effect on the emotional aspect of the pain experience, with less effect on the functional capacity of the patient. The authors of the included studies confirmed that expectation is the most important factor in placebo analgesia, which is also influenced by the physiotherapist through (in)adequate communication. In addition to the individual's expectations, his/her experience and mindset toward the therapy may also determine to what extent the placebo will work. All of these factors vary from individual to individual. Therefore, it is not possible to give a unique answer about placebo effects and factors, and further research in this area is needed in the future.

Published: August 2023

Los divertículos intestinales son sáculos o pequeñas bolsas que se desplazan hacia adelante desde la luz del intestino hacia el exterior de éste, hallándose con más frecuencia en una zona del colon izquierdo llamada sigma. Este término hace referencia a la existencia de divertículos en el colon; y, hablamos de diverticulitis cuando alguno de estos divertículos se inflama. La mayor parte de los divertículos de colon se producen por un aumento en la presión interna del colon. Esto provoca, con el paso de los años, que sus capas internas (mucosa y submucosa) se hernien o prolapsen a través de los puntos de la pared más débiles y con menor resistencia, dando lugar a la aparición de los divertículos. Estos distinguidos galenos explican el tema de una manera sencilla pero científica, fruto de su experiencia en hospitales y clínicas a lo largo del país.

Wood material is destroyed over time by biotic and abiotic factors. Many of the historical buildings are made of wooden materials and these materials can degrade over time with the effect of environmental conditions. In order to ensure the sustainability of these buildings with historical value, they need to be repaired and strengthened over time. In this study, 20x20x360 mm wood specimens of Ash tree species were strengthened with carbon, basalt and glass based FRP materials. The flexural properties of the reference sample without wrapping and the samples reinforced with carbon, basalt and glass based FRP material were examined. For this purpose, at first three-point bending test has been performed, and then obtained results are compared with the numerical ones found from finite element analysis software ANSYS. As result, a good agreement has been found between experimental and numerical results. As a result of the flexural tests, the load-displacement curves, values of flexural strength and values of modulus of elasticity the samples were determined. In this study, it was determined that the highest load carrying capacity value belongs to the sample reinforced with carbon-based FRP polymers.

Enzymatic browning reactions by polyphenol oxidases cause alteration of appearance, flavor and nutritive value of vegetables and fruits. It is one of the important problems for vegetables used as salads and causes lots of economic losses. In this study, polyphenol oxidase (PPO) from Eruca sativa was extracted and characterization studies were carried out. Substrate specificity for variable substrates, optimum pH, optimum temperature, effect of different metal ions were assayed. Km and Vmax values were determined as for pyrocatechol Km = 10.24 mM, Vmax = 0.0018 U min-1, catechin; Km = 12.57 mM, Vmax = 0.0012 U min-1, gallic acid; Km = 23.07 mM, Vmax = 0.0001 U min-1. Optimum pH and temperature were determined as pH:7.0 and 20 oC respectively. Effect of various metal ions such as, K+, Fe2+, Mg2+, Zn2+, Cu2+ and Hg2+ on enzyme activity were measured. K+, Mg2+, Zn2+, Cu2+ ions inhibited PPO activity significantly. However Fe2+ ion did not inhibit PPO activity.

Authors: CELIK Nihat , TOKTAŞ Alaaddin
Published: August 2023

This article proposes a regression model for the shear-cutting process of grain-oriented electrical steel magnetic cores of transformers made from different gages and magnetic properties of steels. In the experimental runs, 3 levels for thickness (230, 270, and 300 µm) and 4 levels for magnetic features of electrical steels are considered. Core steels are supplied as foils and slit to designed lengths in slitting machinery along the rolling direction of coils. The best magnetic features rely on the rolling direction of the coil and the transverse direction of the coil is subject to the shear-cutting process. The result of cutting operations, discontinuities, and degradations in magnetic properties may occur because of deterioration in crystallography and strain gradation on laminated sheets. Shear-cutting process factors have a strong influence on magnetic degradation even the magnitude of the no-load loss of the transformer core. In this study, the mathematical relation between shear cutting factors sheet thickness ST, counts of hits CH, and the response burr length BL is determined using regression modeling. For this purpose, the process parameters of GEORG TBA 400 cut-to-length machinery in use core production is studied. The calculated coefficient of determination is close to almost 1.00 i.e., R2 = 0.9896 which means the factors are sufficient to model the response, and the model is obtained with a good prediction performance. The aim of the present study is building up a useful process control tool for the machinery and raise a discussion alike process in industry.

Two Significant Factors Affecting the Dimensions of the ZnO Nanorods During Chemical Bath Deposition: Precursor Solution Concentration and HMTA Content
Authors: KARDEŞ Memnune , ÖZTÜRK Koray
Published: August 2023

The effects of zinc ion concentration and hexamethylene tetramine (HMTA) content of the aqueous precursor solution on the aspect ratios of the one-dimensional (1D) ZnO nanorods during chemical bath deposition (CBD) were investigated. The ZnO nanorods were grown on these seeded substrates by the low-temperature CBD method at 95 °C for 5 h. In the first part of this investigation the zinc nitrate hexahydrate (ZNH) to HMTA molar ratio was kept constant at a ratio of 1:1 for each of the CBD solutions prepared with different Zn^(+2) ion concentrations of 0.025, 0.035, 0.050, and 0.075 M. The number densities of the nanorods (i.e., number of nanorods per unit area) were increased with the increasing concentration. In the second part, the ZNH to HMTA molar ratio was varied to differ from the 1:1 value and, in turn, to obtain the precursor solutions relatively rich in Zn^(+2) or OH^-ions. Here, the concentration of the precursor solution was kept constant at 0.05 M. The lateral growth perpendicular to the c-axis of the ZnO nanorods was found to be suppressed with the increasing HMTA content (e.g., for the ZNH to HMTA molar ratio of 0.4: 1) due to its capping effect. However, the precursor solution containing an excessive amount of HMTA led to a decrease in the probability of crystal growth, which has been attributed to the OH^- ion enrichment.

Radon Gas Estimation from Building Materials
Authors: BAŞDEMİR Safa , YALÇIN Caner
Published: August 2023

Radon gas originating from building materials is generally thought to cause low concentration. Investigation and estimation of radon levels originating from building materials are important in terms of public health due to the use of dense concrete in tunnel form type houses, which is a building type widely used in Turkey, even though a significant part of Turkey is an earthquake zone. In this article, the effects of different parameters such as 238U concentration in building materials, diffusion constant of building elements, emanation rate, and ventilation rate on radon gas concentration are investigated. As a result, it is concluded that in some cases (such as high diffusion coefficient and insufficient ventilation rate) in houses built with tunnel form concrete structures, the radon level arising from building materials can reach a level that cannot be neglected.

Published: August 2023

In the paper we investigate the dynamics of a life insurance company depending on changes in macro indicators. For the sensitivity study, profitability testing is performed for the average life insurance contract. Profitability testing is based on an estimate of the expected present value of future cash flows. Various approaches to the choice of discount rates are investigated. The choice of strategy for using the rates of the zero-coupon yield curve built on the UAH domestic government bonds is substantiated. The dependence of the zero-coupon yield curve on the change in the key rate is shown. The dynamics of the model at different levels of the interest rates, namely guaranteed investment income, average profitability of investment activity, key rate, is considered. The scenario of the predicted decrease in the key rate at the stage of post-war reconstruction of Ukraine is considered. The profitability of the insurance company was tested based on the macro parameters of the specified scenarios. The expediency of using the chosen approach for researching the dynamics of a life insurance company in the conditions of the current high volatility of the Ukrainian economy is shown.

Published: August 2023

Trigonometric regression models take a special place among various models of nonlinear regression analysis and signal processing theory. The problem of estimating the parameters of such models is called the problem of detecting hidden periodicities, and it has many applications in natural and technical sciences. The paper is devoted to the study of the problem of detecting hidden periodicities in the case when we observe only one harmonic oscillation with discrete time, where random noise is a local functional of Gaussian random sequence with singular spectrum. In particular, the random sequence in the model can be strongly dependent. For estimation of unknown parameters the periodogram estimator is chosen. Sufficient conditions of the consistency of the amplitude and angular frequency periodogram estimator of the model described above are obtained in the paper. The proof of Lemmas 1 and 2 gave an important asymptotic properties of the random noise functional related to the periodogram estimator which necessary for the proof of the main results.

High-quality data recorded by a dense network of 53 seismic stations in the Garhwal–Kumaun Himalaya between February 2017 and December 2021 is analyzed. A total of 813 local earthquakes are relocated using a newly developed regional 1D velocity model incorporating station corrections. In addition, focal mechanism solutions of M ≥ 3.8 events are estimated using waveform inversion. The relocated seismicity patterns along with the focal mechanism solutions are utilized to present a seismotectonic scenario of the region. Almost 95% of the relocated seismicity is found to be clustered along the Himalayan seismic belt (HSB), down to ∼24 km depth. Seismicity in this belt is interpreted to be caused due to interseismic stress loading associated with the ongoing India–Eurasia collision tectonics. A few scattered hypocenters in the deeper crust between 30 and 50 km depth attest the strength of the downgoing Indian plate. Focal mechanisms in the seismogenic upper crust reveal thrusting of the Indian plate beneath the Lesser Himalaya, with compression normal to the strike of the Main Central Thrust (MCT). The north-dipping thrust mechanisms can be associated with a near-horizontal Main Himalayan Thrust (MHT). In addition, more steeply dipping faults above it define the Lesser Himalayan duplex systems, similar to those in western and Nepal Himalaya. A prominent ∼50 km wide seismicity gap region observed within the HSB is probably due to (1) a locally varying locking width of the MHT; (2) an unruptured, ductile segment at the eastern end of the rupture zone of the great 1803 earthquake (Mw 7.8 ± 0.2); and (3) a slab tear in the MHT, similar to those in subduction zones.

DÖVİZ KURU, PETROL FİYATLARI VE DOĞRUDAN YABANCI SERMAYE YATIRIMLARI ARASINDAKİ İLİŞKİ: G7 ÜLKELERİ ÜZERİNE BİR ANALİZ
Authors: BAKKAL Hakan
Published: August 2023

Bu çalışma döviz kuru, petrol fiyatları ve doğrudan yabancı sermaye yatırımları arasındaki ilişkiyi inceleme amacını taşımaktadır. Bu amaçla, petrol tüketiminde ve doğrudan yabancı sermaye
girişlerinde en büyük paya sahip G7 ülkeleri için 1980-2019 dönemine ait verilerle değişkenler arasında eşbütünleşme ve nedensellik ilişkileri araştırılmaktadır. Çalışmada son yıllarda geliştirilen, yapısal kırılmanın formuna ve önceden bilinmesine gerek duyulmayan SOR birim kök testi, Fourier ADL eşbütünleşme ve Fourier Granger nedensellik testleri kullanılmıştır. Elde edilen sonuçlar Almanya, Fransa, İtalya ve Japonya’da değişkenler arasında uzun dönemli bir ilişkiyi göstermektedir. Ayrıca, petrol fiyatları ile döviz kuru ve petrol fiyatları ile doğrudan yabancı yatırım arasında nedensellik ilişkileri mevcuttur. Kanada için reel döviz kuru ile petrol fiyatları arasında çift yönlü nedensellik varken, ABD için reel döviz kurundan petrol fiyatlarına doğru, Almanya için ise petrol fiyatından reel döviz kuruna doğru nedensellik bulunmaktadır. Fransa ve İngiltere’de ise petrol fiyatlarından doğrudan yabancı sermaye yatırımlarına doğru tek yönlü bir nedensellik bulunmaktadır. Petrol fiyat şoklarının yol açtığı döviz kurundaki oynaklık ve üretim maliyetleri üzerindeki baskıyı azaltmak için petrole olan bağımlılığın azaltılması gerekmektedir. Petrol fiyat şoklarının olumsuz etkilerini minimize etmede ülkelerin enerji kaynaklarının çeşitliliğini artırıcı stratejileri uygulaması önem taşımaktadır

RELIGIOUS FREEDOM IN THE USA: SEPARATION BETWEEN CHURCH AND STATE
Authors: YÜKSEL Üstün , BÜYÜKBAŞ Hakkı
Published: August 2023

Religious freedom has been established as a fundamental right in the United States of America (U.S.A.). Thomas Jefferson’s famous ‘wall of separation’ metaphor has taken religious freedom under protection against possible oppression by the state, by building a high wall between church and state. Jefferson’s metaphor established the legal basis of religious freedom as a fundamental human right by defining the boundaries of church and state relations. James Madison also, the author of the U.S. Constitution, attributes a special importance to religious freedom. The U.S. Constitution guaranteed freedom of religion in the First Amendment. American style of church and state separation might be an intriguing topic for Turkish citizens’ constitutional debate. Turkey has been in search of a new and civil constitution recently. In this regard, Former Speaker of the Grand National Assembly İsmail Kahraman proposed in 2021 that Türkiye’s new constitution should ‘guarantee religious freedom for Turkish citizens’. Therefore, we are interested in examining the American style of church and state relations for freedom of religion.
Chess Training for the Elderly: Insights and Prospects as a Dementia Preventive Treatment
Authors: Bart William
Published: August 2023

This article reviews research on chess training as a treatment to promote cognitive fitness and to delay the onset of dementia among the elderly. Alternative treatments are needed to address the widespread problem of dementia among the elderly, primarily because all drug treatments developed thus far to cure or delay dementia have been deemed either unsuccessful or unsafe. Chess training augmented by artificial intelligence is presented as an alternative treatment to address the dementia crisis. Computer-based technology and open-source chess software such as Stockfish 14 with the artificial intelligence component NNUE have the capacity to enhance chess training programs for the elderly. Although research on chess training for the elderly is sparse when compared to research on drug treatments for dementia, one pilot study, as an example, provided evidence that chess training is a viable intervention to improve cognitive fitness among the elderly. The elderly participants in the study enjoyed the chess lessons and looked forward to the challenge and the camaraderie in the group games against artificial opponents available on websites such as chess.com. Chess instruction is a safe, practical, and efficient intervention that should be implemented in community senior centers and retirement villages. Also, chess instruction in community senior centers and retirement villages provides a potentially highly generative and interesting setting for the scientific study of chess and its utility in addressing the enormous public health problem of Alzheimer’s Disease and other forms of dementia. Chess training should be seriously considered as an intervention to be used in research in the quest to promote brain health among the elderly and to protect the elderly from the ravages of Alzheimer’s Disease and other forms of dementia.
Bioética en clave filosófica: el fundamento (bio)ontológico desde la propuesta de Juliana González Valenzuela
Authors: Guerrero Sotelo Roxana Nayeli , Orellana Centeno José Eduardo , López Toledo Sabina
Published: August 2023

El enriquecimiento de las propuestas bioéticas construidas desde y para Latinoamérica ha ido en aumento en las últimas décadas, a efecto de contribuir a ello es que nuestro objetivo es presentar una propuesta de interpretación bioética en clave filosófica a partir de la identificación de los conceptos centrales de la filósofa mexicana Juliana González Valenzuela. Se identificó un doble fundamento bio-ontológico: a) la “fenomenología dialéctica de la vida” que permite la síntesis entre el aspecto biológico y cultural del ser humano, así como la superación de sus contradicciones; y b) el Homo humanus que posibilita la existencia del ser bio-ético afirmado en tanto un ser auténtico y en tanto busca una vida buena (eu-bíos y eu-zoein). La reflexión y crítica de las implicaciones que el fundamento bio-ontológico apareja hipotéticamente al derecho y al poder, nos llevó a identificar las principales líneas argumentativas, pero principalmente se evidenció el vínculo necesario entre el ser bio-ético y dichas disciplinas, en virtud de su naturaleza social y comunitaria (zoon politikón, ζῷον πολῑτῐκόν).
Strategic Plan Of The Major Countries At The Geneva Conference On Indochina And The Position Of The Democratic Republic Of Vietnam On The Issue Of Restoring Peace In Indochina In 1954
Authors: Hoang Dr. Tham Thi
Published: August 2023

On July 21, 1954, the Geneva Accords on Indochina was signed in Geneva, Switzerland, ending the Vietnamese people's long-term resistance war against the French colonialists, completely liberating North Vietnam, opening a new phase of the Vietnamese revolution with the aim of reunifying the country. The signing of the Geneva Accords on Indochina confirmed the first international legal recognition of the three Indochina countries signed and recognized by the major countries attending the Conference. In particular, for Vietnam, this is also the first time that major countries have had to recognize Vietnam's independence, sovereignty and territorial integrity, creating a very important premise and legal basis for Vietnam to continue its struggle against the intervention and aggression of the US imperialists.
Many foreign and Vietnamese scholars have researched and published many works in the form of books and articles from different perspectives and approaches regarding the Geneva Conference and Accords on Indochina. In this article, the author approaches from the perspective of a researcher about the two wars against France and the US of the Vietnamese people on the basis of accessing published domestic and international open sources with the hope of clarifying three issues: 1. Analyzing and clarifying the international context at the time of the Geneva Conference on Indochina; 2. Clarifying strategic intentions and purposes of major countries attending the Geneva Conference on Indochina; 3. Clarifying the position of the Democratic Republic of Vietnam towards the Geneva Conference on the restoration of peace in Indochina.
