Authors: Kuzmenko V. ,   Institute of Mechanics and Automatics of Agroindustrial Production of the National Academy of Agrarian Sciences of Ukraine
Published: July 2024

Purpose. To determine experimentally the effect of the gap between the rollers, the difference in the speed of the rollers on the quality of corn grinding. Methods. Monographic, calculation and design methods were used during the research. The resulting raw wine was analyzed using sieve analysis. The quality of grinding was evaluated by the weighted average particle size – the grinding module and the percentage of particles in the crushed mass less than 40 mm in size. In processing and analyzing the results, statistical and regression analysis methods were used along with graphical methods. Results. According to the experimental results, the closeness of the relationship between the grinding module and the percentage of particles in the crushed mass less than 40 mm in size was determined. The dependence between the size of corn kernels and their weight was established. The dependences of the influence of the gap between the rollers and the difference in the speed of the rollers on the quality of corn grinding were determined. Conclusions 1. The developed experimental roller shredder allows us to study the influence of raw material parameters and design parameters in production conditions: circumferential speed and ratio of roll speeds, gap between rolls, roll compression force, height and pitch of reefs. 2. In the process of ripening, the humidity of the cob decreases from 45 % to 25 %, while the proportion of grain in the cob increases. The length of 80 % of corn kernels is 6–9 mm. The mass of the cob is 75–225 g, the average diameter varies between 34–43 mm and depends on the length of the cob, and these indicators are correlated with each other, the coefficient of determination is R = 0.784. 3. An increase in the compression force of the rollers in the range from 350 to 1750 N, the speed ratio from 1.0 to 2.5 contributes to the improvement of the grinding quality for all standard sizes of the rollers. At the same time, the grinding modulus decreases from 5.8 to 4.0 mm for the studied standard sizes of rollers in the first case and from 6.8 to 3.5 mm in the second case. The nature of the change in dependencies is linear for both cases. An increase in the gap between the rollers worsens the grinding quality. For a gap between the rollers of more than 4 mm, the share of raw materials smaller than 4 mm is only 19–28 %. The nature of dependencies is exponential. Keywords: roller grinder, grinding module, cob, corn grain, dependence, linear regression, coefficient of determination
Climate Change Projections in the Upper Awash River Basin of Ethiopia Using Statistical Downscaling Model
Authors: Cherinet Abirham , G/Yesus Marta
Published: July 2024

Climate change is becoming a major threat to the economic development of developing countries such as Ethiopia. Therefore, understanding the long-term variation and change of climate variables is crucial in developing a plan for sustainable development. This study aimed to project and analyze future climate change in the Upper Awash Basin (UARB) using a statistical downscaling model. Daily data was used every 30-year interval from the second generation of the Earth System Model (CanESM2) under three Representative Concentration Pathways (RCPs). The observed maximum and minimum temperature and precipitation values are a good simulation of the modeled data during the calibration and validation periods using the Pearson coefficient(R), the correlation coefficient(R2), and the Nash-Sutcliffe efficiency (NSE). The downscaled results showed that the mean maximum temperature of upper Awash river basin is likely to increase in the range of 0.32– 0.77°C for RCP4.5 in the 2050s (2041–2070) and 0.43-1.16°C in 2080s (2071–2099), whereas under the worst emission scenario (RCP8.5), the mean maximum temperature of the study area will increase in between 0.52-0.96°C in 2050s and 1.27-2.19°C in 2080s respectively. In the high emission scenario RCP 8.5, the monthly mean maximum temperature increases by 0.5 to 20c in the mid and end of the century. Under medium and high emission scenarios of the far-future period (2080s), the mean annual precipitation will increase by 10.2% and 21.5% compared to the reference period. In both RCP 4.5 and RCP 8.5, rainfall in the Bega/dry season is expected to increase in the 2050s and 2080s while Belg's (February–May) in all emission scenarios for all periods. Whereas in the RCP 4.5 and 8.5 emission scenarios, the Kiremit season is expected to increase in the 2050s and 2080s by 4.6 and 13.9%, respectively. In general, the increase in temperature could worsen the environmental conditions in warm seasons; and an increase in precipitation in the Kiremt season is expected to bring a likely risk of flooding

Published: July 2024

Makala hii ililenga kuchunguza upya wa Utenzi wa Mwana Kupona katika utenzi wa Howani Mwana Howani na Jawabu la Mwana Kupona. Makala hii iliongozwa na nadharia ya Bakhtin kuhusu lugha (1981) na Ufeministi wa Kiafrika iliyoasisiwa na Chioma (1980). Nadharia ya Bakhtin kuhusu lugha inashikilia kuwa lugha huwa na kani za aina mbili: nguvu za Kani Kitovu na Kani Pewa. Nguvu za Kani Kitovu zinafanya kazi kwa kuvuta vipengele vyote vya lugha na mbinu zake za ufasaha kuelekea katikati ili kutoa lugha moja iliyo sanifu au rasmi ambayo kila mmoja anaitumia. Nguvu hizo za Kani Kitovu zilikuwa kanuni zilozounganisha na kuleta kitu katikati. Nguvu za Kani Pewa zilijaribu kusukuma vipengele vya lugha kutoka katikati na kupelekea kuwa na wingi wa lugha au vijilugha. Kwa upande mwingine, Nadharia ya Ufeministi wa Kiafrika iliasisiwa katika miaka ya 1980 na Chioma na Kuendelezwa na Ogundipe (1994), Nnaemeka (2003) miongoni mwa wengine. Nadharia ya Ufeministi wa Kiafrika inafafanuliwa kama mapambano dhidi ya aina zote za dhuluma ili kupiga hatua katika kupata haki za wanawake. Jitihada hizi zinaweza kuwa za kijinsia, ubaguzi wa rangi, unyanyasaji wa kiuchumi kati ya dhuluma nyinginezo zinazolenga kumdhalilisha mwanamke (Bayu, 2019). Utafiti ulikuwa wa kimaelezo. Utafiti ulifanywa maktabani na nyanjani. Sampuli maktabani na nyajani iliteuliwa kimaksudi. Maktabani, mtafiti alisoma kwa kina matini iliyochapishwa kwa lengo la kupata data ya msingi. Nyanjani, mtafiti alifanya mahojiano na majadiliano na wanajamii walioteuliwa katika kukusanya data. Data kutoka katika tenzi zilizoteuliwa, maandishi yaliyohusu utafiti huu, data ya nyanjani zilichambuliwa kulingana na lengo la makala haya na mihimili ya nadharia kwa lengo la kuonyesha namna upya wa Mwana Kupona ulivyobainika katika utenzi wa Howani Mwana Howani na Jawabu la Mwana Kupona. Makala haya yalibainisha kuwa utenzi wa Howani Mwana Howani na Jawabu la Mwana Kupona zilisheheni upya kifani na kimaudhui katika mpito wa wakati.
Pole Assignment for Symmetric Quadratic Dynamical Systems: An Algorithmic Method
Authors: Pantazopoulou S. , Tomas-Rodriguez M. , Kalogeropoulos G. , Halikias G.
Published: July 2024

In this article an algorithmic method is proposed for the solution of the pole assignment problem which is associated with a symmetric quadratic dynamical system, when it is completely controllable. The problem is shown to be equivalent to two subproblems, one linear and the other multi-linear. Solutions of the linear problem must be decomposable vectors, i.e. they must lie in an appropriate Grassmann variety. The proposed method computes a reduced set of quadratic Plucker relations, with only three terms each, which describe completely the specific Grassmann variety. Using these relations one can solve the multi-linear problem and consequently calculate the feedback matrices which give a solution to the pole assignment problem. An illustrative example of the proposed algorithmic procedure is given. The main advantage of our approach is that the complete set of feedback solutions is obtained, over which further optimisation can be carried out, if desired. This is important for problems with structural constraints (e.g. decentralization) or norm-constraints on the feedback gain-matrix.

ADVANCING HUMAN-COMPUTER INTERACTION: EXPLORING THE FRONTIERS OF ARTIFICIAL EMOTIONAL INTELLIGENCE IN INTERACTIVE SYSTEMS AND ITS IMPLICATIONS FOR SOCIETAL INTEGRATION
Authors: Javed Dr. Saman
Published: July 2024

Purpose: Advancements in both computer hardware and software fields are utilized to attain progress across a variety of industries including business, manufacturing, education, health, and governance. However, there is a common denominator irrespective of the application of artificial intelligence (AI) i.e., affective or emotional intelligence (EI) of AI systems. This paper aims to discuss the integration of major elements of EI models into artificial emotional intelligence (AEI) systems.
Design/Methodology: The paper structure is descriptive. Based on 50 studies examining the areas of AI, EI, and AEI, the paper expands the discussion on the interlinks between AI and EI.
Findings: With the availability of big data, advanced data analytical tools, complex algorithms capable of conducting multivariate analysis, expandable memory, and retention, AI embarks on understanding, learning, and applying human emotions, and attaining emotional intelligence. This study proposes that artificial emotional intelligence can be achieved by simulating the learning mechanisms exhibited by human beings.
Research Implications
The indispensable interface between man and machine makes it pertinent to discuss AI’s ability to embrace and internalize human emotions. The study has implications for every industry, especially those that are looking to employ AI tools to assist or replace human counterparts.
Originality
Based on the most renowned model of emotional intelligence presented by Goleman, this study proposes a rudimentary EI model for outlining the basic facets of AEI systems. The study contributes to the literature examining the crossover between AI technologies, emotions, and learning.
A COMPARATIVE REVIEW OF TAEKWONDO TRAINING TECHNIQUES FOR CHILDREN IN CENTRAL ASIA AND THE USA
Authors: Bozorov Asadbek ,   Student of Cuyahoga Community College, Ohio, USA
Published: July 2024

This review looks at how Taekwondo is taught to kids aged 7-10 in Central Asia and the USA. Taekwondo is a Korean martial art that helps kids grow physically and mentally. In Central Asia, Taekwondo training focuses on traditional values and intense physical exercises. Kids learn about respect, discipline, and the history of Taekwondo. In contrast, Taekwondo classes in the USA are designed to be fun and engaging. They include games and rewards to keep kids interested while following a clear step-by-step program. Both methods have their benefits: Central Asia’s approach builds strong discipline, while the USA’s method makes learning enjoyable. The review suggests combining the best parts of both methods could be useful for teaching Taekwondo to kids everywhere.
ANALYZING ETHICAL DILEMMAS IN JOHN GALSWORTHY'S LOYALTIES WITHIN BRITISH SOCIETY THROUGH MAX WEBER'S THEORY OF RATIONALIZATION
Authors: Sabbar Mahmood Shakir ,   Thi Qar University, Department of Cultural Affairs, Iraq
Published: July 2024

The delicate moral complexities encountered by the characters in "Loyalties," a drama by John Galsworthy, expose the subtle workings of British society. This research looks at these problems from the perspective of Max Weber's rationalization thesis, which states that contemporary people put more stock in logic and reason than tradition and emotion. The moral difficulties and tensions brought about by the friction between individual allegiance and social expectations are brought to light by delving into Galsworthy's characters' motives and deeds. The characters' decisions are influenced by rationalization, which frequently causes a conflict between individual ethics and collective standards; Weber's theory helps to explain this. The ethical and social foundations of early 20th-century British society, as portrayed in Galsworthy's writings, are better understood through this study, which also sheds light on the broader effects of rationalization on human behavior and social structures.

Comparative Analysis of Piezo Energy Harvester Optimization Techniques: A Comprehensive Review
Authors: Pushpa Gothwal  , Ajay Kumar
Published: July 2024

Various power optimisation strategies were employed to build the customised and cost-effective PZT tile. It is critical for effective power generation to optimise the performance of PZT-based energy harvesting devices. This research compares three well-known PZT power optimisation techniques: Response Surface Methodology (RSM), Taguchi Method, and Machine Learning. (ML) The benefits, constraints, and applicability of each methodology for diverse circumstances are examined to give researchers and engineers with insights into picking the best optimisation method for their unique applications. According to the observations, the RSM and Taguchi analyses limit the input value. In contradiction ML methods can produce an accurate customised and optimised model. The only limitation with ML approaches achieves the accuracy due to data set limit. This paper presented the comparison review of the optimization techniques and suggested the best power optimization. It also includes the future scope of the methods.

O Sistema de Informações sobre Mortalidade (SIM) é a única fonte de dados com abrangência nacional, estatisticamente confiável e que permite calcular as taxas anuais de homicídio para cada Unidade Federativa (UF) desde 1980. No que se refere aos dados de mortes violentas, dois elementos, contudo, podem conspirar contra a qualidade da informação: o não preenchimento das características das vítimas e das condições em que o incidente ocorreu; e o número de mortes violentas com causa indeterminada (MVCI). Neste trabalho analisamos a qualidade dos dados sobre mortes violentas no SIM entre 2010 e 2021 para cada UF, focando esses dois elementos. Observamos uma deterioração dos dados a partir de 2019, em que o aumento de MVCI pode estar ocultando a verdadeira incidência de homicídios.

A reforma da previdência realizada em 2019 consiste na mais ampla reformulação do sistema previdenciário brasileiro desde a promulgação da Constituição Federal de 1988. Em que pesem importantes mudanças e avanços na sustentabilidade a médio e longo prazo sob a ótica da despesa, persistem grandes desafios para o financiamento futuro da previdência social. Há necessidade de debate mais profundo a respeito do financiamento da previdência e da seguridade social, tendo em vista o processo de rápido e intenso envelhecimento populacional e outras questões – como a expansão da figura do microempreendedor individual (MEI) – que adicionam pressão ao modelo atual de custeio. Este Texto para Discussão apresenta estimativas acerca das alíquotas necessárias ao custeio integral da previdência social, tanto do ponto de vista corrente quanto para a garantia do equilíbrio atuarial entre contribuições esperadas e o pagamento esperado de benefícios. Além da estimativa do que seria uma alíquota de equilíbrio, há que se considerar os diversos tratamentos previdenciários diferenciados – atuarialmente muito subsidiados, como o MEI –, que, a rigor, elevam essa alíquota necessária, além de outras questões. Ressalte-se também a previdência rural brasileira, no âmbito do Regime Geral de Previdência Social (RGPS), bastante desequilibrada e geradora de impactos relevantes sobre o financiamento global da previdência social no Brasil. Este estudo busca complementar os Textos para Discussão nos 2981 e 2988, que também trataram da questão do financiamento previdenciário.

An evaluation of a new equality, diversity, and inclusion activity that uses adaptive comparative judgement to improve delivery and outcomes
Authors: Topping Tony
Published: July 2024

This study evaluates a new introductory equality, diversity, and inclusion activity deployed in a first-year undergraduate engineering programme. It investigates the overall effectiveness of the activity at improving student understanding of equality, diversity, and inclusion (EDI) topics and how the use of adaptive comparative judgement (ACJ) contributed to this understanding. It also explores student perceptions of learning about EDI and participating in ACJ sessions. After completing the activity, students participated in an online survey and a single focus group. Survey results were analysed quantitively whilst focus groups results were analysed qualitatively using reflexive thematic analysis (RTA). Although the activity was somewhat effective at introducing EDI topics, and ACJ had a broadly positive impact, more development work is needed; student engagement with the activity and with their peers needs to be improved, and the way ACJ is deployed and used needs to be optimized.

In this study, we provide an exhaustive investigation of magnetic fluctuations in the first 14 Parker Solar Probe encounters. Our results show (1) enhanced magnetic fluctuations (θ

It is concluded that switchbacks are either generated locally in super-Alfvénic solar wind (in situ) or that a subpopulation of magnetic fluctuations generated in sub-Alfvénic solar corona (ex situ) evolves into switchbacks once in super-Alfvénic solar wind flow. In other words, in situ mechanisms are necessary for switchback formation. It is then hypothesized that interchange reconnection in sub-Alfvénic solar corona can provide both the necessary ex situ trigger and in situ evolution mechanisms for switchback formation, though other trigger mechanisms cannot be ruled out.

Published: July 2024

Introduction: The 2022 mpox global outbreak underscores the need for an improved understanding of mpox epidemiology, co-morbidities, and clinical management/outcome. We report a case of a 30-year-old Nigerian antiretroviral treatment-experienced person living with human immunodeficiency virus (PLHIV) who had PCR-confirmed mpox and chickenpox co-infection.
Case presentation: The patient presented with a generalized itchy rash of three weeks and antecedent low-grade fever. He had no recent travel, animal exposure, or same-sex relationship. Examination revealed generalized pustular and nodular eruptions without peripheral lymphadenopathy.
Results: CD4 count was 78 cells/mm3, wound swab microscopy revealed Gram-positive cocci in clusters and Gram-negative bacilli while culture yielded Pseudomonas aeruginosa. Despite supportive care and definitive antimicrobial therapy, his clinical condition deteriorated with sepsis-related multi-organ dysfunction and ultimately death.
Conclusions: Mpox and chickenpox co-infection may occur, with potentially fatal complications in the setting of advanced HIV disease. Increased surveillance for co-viral infections in PLHIV with febrile exanthema and aggressive management to improve outcome are recommended.

Introduction: Arterial and venous thrombotic events in COVID-19 cause significant morbidity and mortality. For optimal thromboprophylaxis treatment for hospitalized patients, especially those with severe COVID-19 symptoms, it is still unclear whether to use full- or therapeutic-dose versus prophylactic-dose anticoagulation therapy. The study aim was to evaluate the efficacy and safety of unfractionated heparin (UFH) for thromboprophylaxis in severe degree of COVID-19.
Methodology: In this cross-sectional study, the medical records of 160 COVID-19 patients at the COVID-19 Emergency Hospital Wisma Atlet, Jakarta, from March to August 2021, were collected. The predetermined inclusion criteria for patients were severe COVID-19 infection; age > 18 years; positive D-dimer level > 400 ng/mL; high-flow nasal cannula (HFNC) oxygenation; IMPROVE bleeding risk score < 7; and willingness to participate in the study. The primary outcome was activated partial thromboplastin time (APTT) target achievement, oxygenation changed to nasal cannula or ended with room air, mortality rate, and the principal safety criterion was presence of bleeding.
Results: Of 160 subjects, 63.8% were male and 45.6% were aged 45-59 years old. Obesity was the most common comorbidity at 45.6% Among all subjects, 9.4% experienced bleeding, with hematuria being the most frequent type at 66.7%. All subjects released HFNC, and no deaths were reported.
Conclusions: It can be concluded that administration of therapeutic doses of heparin in patients with severe COVID-19 had a low risk of bleeding and no patients were reported to have died. However, further investigation is needed to determine the long-term effects of therapeutic doses of anticoagulants.

Authors: Onaghinor Iyonu J , Achusi Izuchukwu B , Ariyo Olumuyiwa E
Published: July 2024

Introduction: Breast tuberculosis (TB) is a rare extra-pulmonary presentation of tuberculosis. In the western world, this accounts for less than 0.1% of breast conditions (all breast conditions, not limited to TB or extra-pulmonary TB), but can be up to 3-4% in regions endemic for TB such as in Africa and Asia.
Case presentation: We report a case of a 54-year- old human immunodeficiency virus (HIV)-positive lady who presented with six months history of multiple masses on the left breast which were initially suspected to be cancer of the breast. However, histology report of the mass confirmed TB of the breast.
Conclusions: Presentation of TB can be non-specific and atypical in patients with HIV infection, especially when it presents in extra-pulmonary forms.

Introduction: In Egypt, there is a paucity of new data regarding awareness of HIV/AIDS among physicians. This study aimed to assess the level of awareness, attitude, practice, and knowledge of a sample of Egyptian physicians regarding HIV regarding natural history, epidemiology, and virology, method of transmission, clinical manifestations, diagnosis, prevention, and management.
Methodology: Sixty-eight Egyptian physicians were enrolled in an observational analytic multicenter cross-sectional KAP study in Egyptian tertiary health care facilities covering different localities, including New Valley University, Assiut University, South Valley University, Helwan University, Alexandria University, Aswan University, and Al-Azhar University.
Results: The attitude of physicians towards the privacy of persons living with HIV, was the one with the highest percentage 85.3%. On the other hand, respondents think that only 25% of physicians do not stigmatize HIV patients. Moreover, only 25% of the study group do not stigmatize persons living with HIV. The highest proportion of favorable practice was 39.7% and the lowest was 17.6%. With regard to their knowledge about HIV, the lowest proportion of correct answers to a question was 4.4%, and the highest proportion was 92.6%. Most of the enrolled physicians were found to have a moderate knowledge score, 49/68 (72%). There was a significant difference between different specialties regarding knowledge scores.
Conclusions: There are some knowledge gaps among a sample of Egyptian physicians with regard to HIV/AIDS. In addition, Egyptian physicians may have a moderate degree of undesirable attitude and practice toward HIV/AIDS.
Non-fragile sampled-data control for synchronizing Markov jump Lur'e systems with time-variant delay
Authors: Zuo Dandan , Wang Wansheng , Zhang Lulu , Han Jing , Chen Ling
Published: July 2024

The issue of non-fragile sampled-data control for synchronizing Markov jump Lur'e systems (MJLSs) with time-variant delay was investigated. The time-variant delay allowed for uncertainty that was constrained to an interval with defined upper and lower boundaries. The components of the nonlinear function within the MJLSs were considered to satisfy either Lipschitz continuity or non-decreasing monotonicity. Numerically tractable conditions that ensured stochastic synchronization with a predefined $ \mathcal{L}_{2}-\mathcal{L}_{\infty} $ disturbance attenuation level for the drive-response MJLSs were established, utilizing time-dependent two-sided loop Lyapunov-Krasovskii functionals, together with integral and matrix inequalities. An exact mathematical expression of the desired controller gains can be obtained based on these conditions. Finally, an example with numerical simulation was employed to demonstrate the effectiveness of the proposed control strategies.

In this paper, we classified Hadamard $ 2 $-$ (51, 25, 12) $ designs having a non-abelian automorphism group of order 10, i.e., $ {\rm{Frob}}_{10} \cong Z_5:Z_2 $, where a subgroup isomorphic to $ Z_2 $ fixed setwise all the $ Z_5 $-orbits of the sets of points and blocks. Furthermore, we classified $ 2 $-$ (59, 29, 14) $ designs having a non-abelian automorphism group of order 14, i.e., $ {\rm{Frob}}_{14} \cong Z_7:Z_2 $, where a subgroup isomorphic to $ Z_2 $ fixed setwise all the $ Z_7 $-orbits of the sets of points and blocks. We also showed that there was no Hadamard $ 2 $-$ (59, 29, 14) $ design with automorphism group $ {\rm{Frob}}_{21} \cong Z_7:Z_3 $, where a subgroup of order 3 fixed setwise all the $ Z_7 $-orbits of points and blocks. Additionally, we used Hadamard $ 2 $-$ (59, 29, 14) $ designs obtained to construct ternary linear codes and linear codes over the finite field of order 5. We constructed ternary self-dual codes and self-dual codes over the finite field of order 5 from the corresponding Hadamard matrices of order 60.

Nosso objetivo neste artigo é apresentar o capitalismo como religião contemporânea, tendo o dinheiro como Deus e o marxismo e o liberalismo como correntes proféticas. O texto se divide em três momentos. Na primeira parte, buscamos definir “religião” a partir do conceito fundamental de Pulsão, tal como definido pelo psicanalista MD Magno. Na segunda parte, com base no texto clássico de Walter Benjamin e no recém-lançado “The enchantments of Mammon” de Eugene McCarragher, buscamos caracterizar o capitalismo como religião do nosso tempo. E por fim, analisando passagens das obras de Marx, Smith, Mises e Hayek, procuramos demonstrar que marxismo e liberalismo são vertentes proféticas da religião capitalista.
Contingência, correlacionismo e realidade:
Authors: Da Silva Leonardo Domingos Braga
Published: July 2024

Este trabalho examina as ideias filosóficas de contingência, correlacionismo e realidade, com foco nas críticas formuladas por Slavoj Žižek e Markus Gabriel ao projeto de Quentin Meillassoux. Žižek destaca uma crítica à absolutização da contingência em Meillassoux, argumentando que o filósofo não consegue verdadeiramente superar o correlacionismo kantiano. Žižek, ao contrário, defende a correlação transcendental como parte integrante da própria coisa em si, enfatizando a importância de entender a relação entre como as coisas são em si mesmas e como aparecem para um sujeito. Por outro lado, Markus Gabriel contribui ao enfatizar os modos de apresentação na constituição da realidade. Ele aborda a ideia de que a diferença entre como as coisas são em si mesmas e como são apresentadas é constitutiva da realidade. Gabriel explora a diversidade de modos pelos quais a realidade se manifesta, destacando a complexidade da relação entre sujeito e objeto. O texto também aborda a crítica de Žižek ao projeto meillassouxiano de buscar o em si lá fora, defendendo que a contingência não é apenas um aspecto externo à subjetividade, mas também inerente ao próprio sujeito como um corte no circuito da causalidade natural. Ao longo do artigo, são evidenciadas as divergências e contribuições desses filósofos, proporcionando uma análise aprofundada das relações entre contingência, correlação e a natureza fundamental da realidade. A interseção dessas críticas fornece uma perspectiva de leitura sobre os desafios e implicações da abordagem de Meillassoux no cenário filosófico contemporâneo.
Em busca de indícios do fetichismo da tecnologia na geografia crítica de Milton Santos
Authors: Dos Santos Matheus Henrique
Published: July 2024

Os sistemas e objetos tecnológicos pelos quais os modos de vida são inundados na atualidade são elementos imprescindíveis tanto para a análise crítica quanto para a compreensão do tipo de sociedade a que se almeja pela participação democrática. Diante disso, se opta por pontos de vistas diametralmente opostos: as tecnologias são necessariamente boas e contribuem para o desenvolvimento humano ou são, por outro lado, mecanismos de desumanização gradual. O objetivo desta escrita é demarcar a possibilidade de uma crítica efetiva a tecnologia sem abdicar de seu caráter ontológico, quando apoiada na necessidade da técnica para a transformação do mundo e construção de um espaço próprio a realização da vida humana. Para isso, buscou-se no conteúdo filosófico da obra de Milton Santos, pistas para compreender os conceitos de fetichismo da mercadoria e da tecnologia, de modo a reconstituir a relação mais direta e ativa dos sujeitos com o mundo, o espaço no qual realizam suas vidas, condição na qual o capitalismo opera uma mistificação sobre os objetos e os sujeitos. Conclui-se que um olhar a partir do espaço geográfico torna-se relevante para a análise da tecnologia, tendo em vista que congrega não só a estrutura de significado pela qual nossas ações são constituídas, mas os efeitos concretos, no espaço, dos sistemas de ações e objetos ligados a determinada vetorização de um poder que articula ideologicamente nossa relação com o mundo. Não é a tecnologia por si uma problemática, mas o modo pelo qual ela adquire valor em nosso contexto de vida.
Tradução do original "Aristotle's philosophy of mind", de Terence H. Irwin

A presente tradução pretende contribuir para o debate em torno da filosofia da mente em Aristóteles e, para tal, buscou-se enriquecer a discussão trazendo para a língua portuguesa o texto de Terence Irwin, autor referência na área, “Aristotle’s theory of mind”. Aristóteles em seu livro Sobre a Alma, traça importantes considerações sobre a mente, já que defende todos os seres vivos têm alma e dentre eles, há um subgrupo que apresenta mente. Mas até que ponto podemos traças paralelos entre os debates da filosofia da mente contemporâneos e as reflexões do assunto feitas por Aristóteles? Nesse sentido, Irwin pretende defender que as visões de Aristóteles sobre alma e corpo podem ser proveitosamente comparadas com as opções familiares dos debates sobre mente e corpo, e que uma comparação cuidadosa permite a conclusão bastante definitiva de que ele aceita uma posição reconhecidamente funcionalista.

Authors: Nguyen Minh Thi Binh
Published: July 2024

Our paper was conducted to certify the role of employee well-being, job satisfaction, and post-Covid-19 syndrome in the job performance of employees working at Linh Trung Export Processing Zone in Ho Chi Minh City. Based on previous theoretical and empirical studies, we constructed the research conceptual framework and hypotheses. We applied a convenience sample method and conducted a direct survey with 439 respondents who suffer from post-Covid-19 symptoms. SPSS 25 software and AMOS 24 software were used to test hypotheses. The results illustrated that employee well-being and job satisfaction had a positive and strong relationship with employee performance, while post-Covid-19 syndrome strongly and negatively impacted employee performance. Moreover, the factors affecting employee performance in descending order were employee well-being, job satisfaction, and post-Covid-19 syndrome. Finally, we showed some theoretical and practical contributions to enhancing the level of performance of employees working at Linh Trung Export Processing Zone in Ho Chi Minh City as well as at other companies in Vietnam suffering from post-Covid-19 syndrome.

A Faithful and Quantitative Notion of Distant Reduction for the Lambda-Calculus with Generalized Applications
Authors: Santo José Espírito , Kesner Delia , Peyrot Loïc
Published: July 2024

We introduce a call-by-name lambda-calculus $\lambda Jn$ with generalized
applications which is equipped with distant reduction. This allows to unblock
$\beta$-redexes without resorting to the standard permutative conversions of
generalized applications used in the original $\Lambda J$-calculus with
generalized applications of Joachimski and Matthes. We show strong
normalization of simply-typed terms, and we then fully characterize strong
normalization by means of a quantitative (i.e. non-idempotent intersection)
typing system. This characterization uses a non-trivial inductive definition of
strong normalization --related to others in the literature--, which is based on
a weak-head normalizing strategy. We also show that our calculus $\lambda Jn$
relates to explicit substitution calculi by means of a faithful translation, in
the sense that it preserves strong normalization. Moreover, our calculus
$\lambda Jn$ and the original $\Lambda J$-calculus determine equivalent notions
of strong normalization. As a consequence, $\lambda J$ inherits a faithful
translation into explicit substitutions, and its strong normalization can also
be characterized by the quantitative typing system designed for $\lambda Jn$,
despite the fact that quantitative subject reduction fails for permutative
conversions.
Klebsiella pneumoniae ve Acinetobacter baumanni Suşlarında Kolistin Duyarlılığının Saptanması: Yöntem Karşılaştırması
Authors: Koçer İpek , Demirbakan Hadiye
Published: July 2024

Amaç: Bu çalışma ile çok ilaca dirençli Gram negatif bakterilerde kolistin duyarlılığı için sıvı mikrodilüsyon (BMD) temelli ticari sistem ile kolistin sıvı disk elüsyon (CBDE) yöntemlerinin karşılaştırılması amaçlanmıştır.
Araçlar ve yöntem: Mart 2020 - Haziran 2022 tarihleri arasında çeşitli klinik örneklerinden izole edilen 112 K. pneumoniae ve 62 A. baumannii izolatı çalışmaya alındı. Suşların kolistin duyarlılıkları BMD temelli ticari sistem ve CBDE yöntemleri ile karşılaştırıldı.
Bulgular: K. pneumoniae izolatlarının CBDE test sonuçları ile BMD temelli ticari kit sonuçları arasında çok iyi uyum bulunmuştur (κ = 0.88). A. baumannii izolatlarının CBDE test sonuçları ile BMD temelli ticari kit sonuçları karşılaştırıldığında ise önemsiz düzeyde uyum bulunmuştur (κ = 0.11).
Sonuç: CBDE yönteminin Enterobacterales takımında kolistin duyarlılığının belirlenmesinde uyumu yüksektir. Acinetobacter izolatlarında ise uyum düzeyinin düşük olması altın standart BMD yöntemine alternatif rutin laboratuvarda uygulanabilir yöntemlere ihtiyaç olduğunu göstermektedir.

Authors: Altun İbrahim , Peker Gökhan
Published: July 2024

Amaç
Bu çalışmada amaç, Lindgren-turan osteotomisi ile beraber kapsüloplasti ve buniektomi uygulanan orta ve şiddetli halluks valguslu (HV) hastaların klinik ve radyolojik sonuçlarını değerlendirmektedir.
Hastalar ve yöntem
HV deformitesi olan, Modifiye Lindgren-Turan prosüdürü uygulanan 71 hasta orta ve uzun dönem sonuçları kontrollü kohort tip retrospektif olarak değerlendirilmiştir. Hastaların 54 (%76,1)’ü kadın ve 17 (%23,9)’si erkek, tüm hastaların ortalama yaşı 44,04±11,28 (min-max: 18-77) yıl ve ortalama 52,76±9,7 (min-max: 38-78) ay takip edildi. Hastalar klinik sonuçları AOFAS ve VAS ile değerlendirilirken, radyolojik olarak röntgenogram ile ameliyat öncesi ve sonrası halluks valgus açısı (HVA), distal metatarsal eklem açısı (DMAA), 1. ve 2. Metatars arası (İMA) açı ve metatars kısalıkları değerlendirildi. Çalışmada orta ve şiddetli halluks valguslu hastalar 2 gruba ayrıldı, hem grup içi hem de tüm hastaların ameliyat öncesi ve sonrası sonuçları SPSS 22 programında related-samples Wilcoxon Signed test ile analiz edilerek değerlendirilmiştir.
Bulgular
Tüm hastalarda ameliyat öncesi HV açısı, İMA ve DMAA değerleri sırasıyla 34,96±4,90, 12,56±1,80, 15,6±5,5 iken ameliyat sonrası ise 12,77±3,20, 6,67±1,450, 7,32±3,2’e düştüğü tespit edildi (p=0,001). Klinik olarak ise ameliyat öncesi AOFAS ve VAS değerleri sırasıyla 50,5±9 ve 7,41±0,93 iken ameliyat sonrası 80±6,5 ve 2,63±0,63 idi (p=0,001). 3 hastada yüzeyel enfeksiyon meydana geldi ve antibiyotik tedavisi ile düzeldi. 1 hastada ise kaynamama olması üzerine plak ile revizyon yapıldı.
Sonuç
Modifiye Lindgren-Turan osteotomisi ile hafif metatars kısalığına neden olmakla beraber buna bağlı olarak herhangi bir komplikasyona yol açmamaktadır. Bu metod ile mevcut deformiteler düzeltilebilmekte, klinik ve radyolojik olarak iyi sonuçlar elde edilebilmektedir.

Published: July 2024

Purpose: We aimed to investigate body satisfaction and somatisation levels in individuals diagnosed with obsessive-compulsive disorder (OCD).
Materials and Methods: For this purpose, 84 patients diagnosed with OCD who met the inclusion and exclusion criteria were included in our study. Structured Clinical Interview for DSM (SCID-5), Yale Brown Obsessive Compulsive Disorder Scale (Y-BOCS), Body Image Scale (BIS), Bradford Somatic Inventory (BSI-44) were applied to the participants.
Results: It was observed that the most common obsession of the participants was contamination, followed by other obsessions group and aggression, respectively. The most common compulsion was controlling compulsion, followed by cleaning and repetitive ritualistic compulsions, respectively. It was determined that the mean score of the participants was 21.7±7.7 points on the Y-BOCS, 137.6±26.3 points on the BIS, and 25.8±17.8 points on the BSI-44, and female scored statistically significantly lower than male on the BIS, while there was no significant difference between male and female in the other scales. It was observed that body image was higher in those with ordering and organising compulsions. Somatisation was found to be higher in those with accumulation, symmetry, somatic and repetitive ritual compulsions.
Conclusion: Body image and somatisation level of patients with OCD vary according to both sociodemographic characteristics and types of obsessions and compulsions. Our findings make an important contribution to the very limited literature on this issue.
