Sobre os Diversos Modos de Apreensão do Eu no Itinerário Husserliano
Authors: Carvalho Tássia Vianna de
Published: December 2024

Pretendemos, neste artigo, apresentar as transformações que a noção de Eu ganha no decorrer do itinerário husserliano; desde a sua exclusão do campo de investigação de uma fenomenologia das vivências, tal como ocorre na Investigações Lógicas, especificamente na 5ª investigação, até a descoberta do Eu Transcendental, como polo ao qual os vividos remeteriam, com a instituição de uma fenomenologia transcendental como aparece no Ideias I. Desaguando, por fim, em uma investigação a respeito da gênese constituição deste Eu, tal como será requerida pela investigação fenomenologia de teor propriamente genético. Investigaremos, portanto, as distinções e relações entre estas noções de Eu, em vistas de mostrar que não se tratariam de múltiplos Egos, compreendidos como objetos distintos, mas estes consistiriam em diversos modos de apreensão de um mesmo Eu, a saber, um Eu Funcional.
A indissociabilidade entre subjetividade e objetividade em Sartre
Authors: Lessa Lucas Marques
Published: December 2024

Procura-se demonstrar que a ontologia fenomenológica afasta Jean-Paul Sartre dos realismos e dos idealismos clássicos, uma vez que, embora na aparição os dois tipos de seres se dão conjuntamente, seu método aponta para uma distinção entre ser-Em-si e ser-Para-si. Se no plano ontológico os seres encontram-se separados, fenomenologicamente se nota a união entre eles. À vista dessa confluência factual entre esses dois seres, ensejam-se a preeminência da existência por parte em Em-si e a preeminência da significação por parte do Para-si. Sendo assim, trata-se de mostrar ainda que, na intrincada relação entre objetividade e subjetividade, o Para-si, por possuir o condão de outorgar sentido à realidade ôntica, não se encerra em sua facticidade e é capaz de transcendê-la, em que pese se ver diante de situações incontornáveis e por ele não desejadas.

Published: December 2024

Este texto objetivou compreender a concepção de um grupo de professores sobre o desinteresse escolar dos alunos e suas relações com a indisciplina. Para coleta de dados da pesquisa, foi aplicado um questionário para professores de Ciências e Biologia da Educação Básica de um município no Oeste do Paraná. Os dados foram analisados mediante Análise Textual Discursiva (ATD). Da análise dos resultados emergiram quatro categorias, das quais elegemos a categoria “Geração Digital” para a produção do metatexto. Constatamos que os meios digitais emergem como um fator significativo, dos quais estabelecem estreitas relações com os indicativos do desinteresse escolar, bem como a falta de compreensão sobre os objetivos da educação científica e também a falta do conhecimento das regras disciplinares são fatores que levam a manifestação da indisciplina. Ponderamos que para minimizar as situações de indisciplina e do desinteresse escolar é preciso considerar uma diversidade de concepções e contextos envolvidos, e para isso é necessário estabelecer uma diretriz disciplinar consistente, que promova uma cultura de respeito e diálogo, bem como buscar constantemente estratégias pedagógicas inovadoras que promovam o engajamento e a motivação dos professores e alunos no processo de ensino e aprendizagem

Published: December 2024

Esta proposta tem como objetivo discorrer sobre a elaboração de um modelo didático que facilite o ensino de Química Orgânica para estudantes com deficiência visual e passível de aplicação para outras estruturas químicas.  O ensino de Química muitas vezes se mostra de difícil compreensão por trabalhar conteúdos abstratos, o que ocasiona muitas dificuldades de aprendizagem para os estudantes da educação básica e superior, além de gerar visões equivocadas sobre essa ciência. Desta forma, destacamos a importância do uso de modelos didáticos táteis que possibilitam a percepção de estruturas moleculares na dimensão macroscópica, seja para alunos com deficiência visual ou normovisuais na área de química orgânica. Partimos de um sobrevôo pela literatura da área para mostrar a importância da educação inclusiva e as dificuldades de se compreender o ensino de Química, principalmente pela complexidade e constante uso de modelos teóricos apresentados apenas oralmente pelos docentes. O modelo didático tátil proposto aponta um caminho que contribui para o ensino de Química Orgânica, especificamente o conteúdo de hidrocarbonetos e com o rol de pesquisas que se dedicam a um ensino de Química mais inclusivo e produção de materiais didáticos

RESEARCH ON THE IMPACT OF PERCEIVED ORGANIZATIONAL SUPPORT ON PRESCHOOL TEACHERS' TURNOVER INTENTION
Authors: Dai Yu  , Xue Shuyin
Published: December 2024

To promote high-quality development in preschool education and explore the relationship between preschool teachers' perceived organizational support and turnover intention, a survey was conducted among 932 preschool teachers in Guangdong Province. The findings reveal that preschool teachers' overall perceived organizational support score is at a high level, while their turnover intention score is slightly below average. This indicates that certain achievements have been made through the nation's implementation of measures to further deepen the reform of preschool education. With perceived organizational support serving as a protective factor against preschool teachers' turnover intention, this study further explores the relationship between these two variables. These research findings have practical significance for kindergartens in improving preschool teachers' work happiness and reducing turnover rates.

cinematografía mexicana como discurso nacional: las bases del antiyanquismo
Authors: Flores Moreno Marco Antonio
Published: December 2024

Se mostrará cómo la cinematografía nacional transitó de ser una diversión para la oligarquía a un producto de consumo popular, ligado a la inversión estatal y a las necesidades de la política.  Se podrá ver cómo desde el gobierno de Porfirio Díaz (Oaxaca, 1830-1915) hasta los inicios del gobierno de Manuel Ávila Camacho (Teziutlán, 1897-1955), se trató de articular un sentido de nacionalismo a través del cine. De esta manera, el gobierno trató de controlar los valores de la mexicanidad y dictar un papel a cada sector de la sociedad.
Analiza potencjału administracji publicznej Ukrainy w kontekście procesu europeizacji
Authors: Litwin-Lewandowska Dorota
Published: December 2024

Europeanization is a process occurring in the public administration structures of EU Member States and those in the process of European integration and involves the implementation of solutions and, as a result, the adaptation of national administrations to the European model of public administration. There is a paucity of studies on this issue in the literature, especially from the perspective of the current challenges facing the public administration of Ukraine in connection with the ongoing public administration reform. The fundamental research problem is the analysis of the potential of the Ukrainian government administration in the process of adapting the national public administration to the requirements resulting from the European integration process. This reform is one of the priority reforms in countries applying for EU membership, and the progress of the integration process depends on an effective public management system. The aim of the research was to analyze Ukraine’s ability to formulate and coordinate state policy as one of the dimensions of public administration modernization, but also to demonstrate how the EU supports this process. Russia’s aggression against Ukraine significantly disrupted the process of Europeanization of administration and verified policy priorities. Despite this, Ukraine has achieved a satisfactory level of preparation in the area of public administration reform. A success that proves the expansiveness and mobility of Ukraine’s central administrative bodies is that the policy-making system is capable of performing critical functions that guarantee coherent, competent, and efficiently organized policy conduct, even in a situation of full-scale war.
Wpływ konfliktu rosyjsko-ukraińskiego na ewolucję polityki zagranicznej Grecji
Authors: Adamczyk Artur
Published: December 2024

The main goal of this article is to present the evolution of Greece’s foreign policy, especially towards Russia and Ukraine, in the context of the impact that the outbreak of the Russian-Ukrainian conflict in 2022 had on this evolution. In order to present the fundamental reasons for the changes in Greek foreign policy, it was necessary to outline the main determinants shaping this policy, which primarily include the permanent sense of threat to the security and territorial integrity of Greece from Turkey. The analogy between Russian aggression against Ukraine, underpinned by revisionist arguments, and Ankara’s aggressive policy towards Athens, questioning the ownership of the Aegean islands to Greece, was emphasized. It was also pointed out that, as a consequence, Greece is now firmly against Russia and is supporting Ukraine both humanitarianly and militarily, counting on the fact that in a similar situation of the Turkish threat, its NATO and EU allies will provide it with strong support.

Authors: Kowalik-Bylicka Joanna
Published: December 2024

The article discusses events from 1706 to 1709, associated with the Great Northern War in the Polish-Lithuanian Commonwealth, focusing on the reign of Stanisław Leszczyński and the role of Stanisław Antoni Szczuka by the king’s side. Primary sources include the correspondence of Lithuanian Grand Chancellor Karol Stanisław Radziwiłł (1669-1719), particularly letters from royal secretaries Samuel Kazimierz Szwykowski and Jozafat Michał Karpi, which document daily events of the war in the Commonwealth. These letters were published in two volumes by Jerzy Dygdała in 2018 and 2019 and include information from contemporary newspapers, excerpts from Radziwiłł’s diary, and an attributed account of the king’s journey to Saxony by Szczuka. Additional sources feature correspondence between Stanisław Antoni Szczuka and his wife, Konstancja Potocka Szczuka, as well as court expenses from this period. During Leszczyński’s reign, Szczuka served as an advisor and royal minister, overseeing the royal chancellery, preparing documents for the monarch’s signature, and receiving diplomatic missions. The letters of Szwykowski and Karpi reflect Leszczyński’s trust in Szczuka, who was known for his wisdom, dedication to the Commonwealth, and advocacy for national unity. Renowned for his oratory skills, Szczuka expressed skepticism toward the political and military plans of Charles XII and disapproved of the Swedish army’s conduct in the Commonwealth.

A Linear Programming Approach to Invest Provident Fund of Retirees
Authors: - Preeti Bhide
Published: December 2024

Old age is an unavoidable period in everyone’s life. Although, it cannot be avoided everyone tries to make it easier at least by financially by proper pre-planning. Many government employees in India have pensions but the people working in private sector do not get it. But they receive a one-time Provident Fund (PF) at the time of retirement. This paper proposes a Linear Programming (LP) model to help retired individuals to strategically invest their Provident Fund in multiple asset classes. By considering factors such as risk, amount of investment and return rates, the model provides optimized investment suggestions to maximize returns without compromising financial security. The model uses LP to determine the best portfolio allocation, offering retirees a quantitative tool to enhance their investment decisions by properly verifying all the possibilities.
Magnetic behaviour of Er and Mg doped Bismuth ferrite Nanocomposites: Synthesis and its Characterization.
Authors: - Thirumoorthi.A
Published: December 2024

Multiferroic materials have significant attention due to the coupled magnetic, ferro- electric and ferro-elastic orders. Among all multiferroic materials, bismuth ferrites (BiFeO3, BFO) are the only single-phase room temperature multiferroic materials known, and have multifunctional applications. Bismuth ferrite possesses magnetic ordering of antiferromagnetic with a spatially modulated spin structure. Consequently, many researchers are engaged in releasing the ferromagnetism from space-modulated spin structure. This paper provides insights into the synthesis and characterization of Er3+ and Mg2+ co–doped single-phase BFO nanocomposites namely BEFO, BEFMO–1 and BEFMO–2 with different mole ratios of magnesium by sol-gel method. FT – IR spectra confirmed the presence of Bi/Er –O bonds in doped BFO and the Raman spectra indicates the structural transformation of rhombohedral to orthorhombic. SEM images showed the undoped and doped BFO nanocomposites synthesized were spherical in shape and PL studies revealed that the reduction in the density of oxygen vacancies causing decrease in electron-hole recombination. Bismuth ferrites provide enhanced magnetic (Ms, Mr and Hc) behaviours due to doping of Er and Mg.

Abstract
Satisfaction is a state of mind. It is an evaluative appraisal of something. The term refers to both “contentment” and “enjoyment”. As such it covers cognitive as well as affective appraisals. Satisfaction can be both evanescent and stable through time. Current synonyms for life satisfaction are “happiness” and “subjective well-being”. One advantage in using the term “life-satisfaction” rather than the word “happiness” is that it emphasizes the subjective character of the concept. The word happiness is also used to refer to an objective good; especially by philosophers. The term life-satisfaction has the advantage over the label of “subjective well-being” is that life-satisfaction refers to an overall evaluation of life rather than to current feelings or to specific psychosomatic symptoms. The concept of life satisfaction is part of a broader field of enquiry, commonly referred as Quality of Life (QoL), which is one of the prime areas of interest in positive psychology. The prime concern in that field is to develop criteria for the good life. Older farmers are often viewed as less flexible and less willing to engage in a new or innovative activity due to fear of risk whereas young farmers may take more risk averse to implement new technologies on their farm. Hence the influence of age on farmers’ satisfaction is to be researched. The data obtained were quantified and put to statistical analysis for drawing meaningful conclusions. This paper concluded that there was an overall positive response of farmers and need for a strategy to improve farmer’s life satisfaction.

Evaluating the Influence of Different Colors on Nocturnal Insects Attraction: Behavioral and Ecological Implications
Authors: - Pawan Kumbhar , - A. R. Bhusnar
Published: December 2024

This study investigates the phototactic behavior of insects in response to different wavelengths of light, specifically red, blue, and white light. Phototaxis, the movement of organisms toward or away from light, plays a crucial role in insect navigation, foraging, mating, and migration. The experiment involved using light traps exposed to the three light colors from 7:00 PM to 10:00 PM over a 15-day period to assess insect attraction. Due to the sensitivity of insect compound eyes to shorter wavelengths, nocturnal species were hypothesized to be most attracted to blue light, which resembles natural twilight and serves as a navigational cue. In contrast, red light was expected to elicit minimal attraction due to its longer wavelength, which many insects cannot detect effectively. White light, containing a broad range of wavelengths, was anticipated to produce a mixed response depending on species-specific visual sensitivity. The findings provide insight into how light wavelength influences insect phototaxis, with potential applications in ecological research and pest management strategies.

Published: December 2024

This study investigates the dynamic changes in the concentrations of various volatile organic compounds (VOCs) in edible oils subjected to prolonged heating. Using High-Performance Liquid Chromatography (HPLC) with a UV detector at 254 nm, we measured the concentrations of α-methyl styrene, β-methyl styrene, ortho xylene, meta xylene, para xylene, benzene, toluene, ethyl benzene, propyl benzene, isopropyl benzene, and iso-butyl benzene in coconut, cottonseed, groundnut, mustard, palm, rice bran, sesame, sunflower, rapeseed, safflower, and soybean oils over heating durations of 0, 2, 4, and 6 hours. The results provide a detailed illustration of the behaviour of these compounds under heat: Mustard oil initially had high concentrations of α-methyl styrene (103.00 µg/Kg) and β-methyl styrene (110.00 µg/Kg) which decreased to 46.00 µg/Kg and 52.00 µg/Kg. Cottonseed oil started with high benzene levels (48.00 µg/Kg) which were significantly reduced to 3.00 µg/Kg. Rice bran oil displayed an initial benzene concentration of 10.00 µg/Kg that reduced to 2.10 µg/Kg. Coconut oil, starting at 36.00 µg/Kg of benzene, saw a reduction to 3.00 µg/Kg. Palm oil began at 21.00 µg/Kg of benzene and decreased markedly to 0.02 µg/Kg. The reduction rates varied, indicating that different oil types have distinct thermal stability and volatile emission behaviours under similar heating conditions. This comprehensive dataset underlines important implications for food safety, especially concerning the selection and use of cooking oils in environments where prolonged heating is common, affecting both culinary quality and occupational health safety.
Evaluation of land resources for sustainable agricultural land use planning: A case study
Authors: Nagdev Ritu , Meena R.K. , Kumar Ashok , Joon Vikas , Surya Jaya N.
Published: December 2024

Various soil and water constraints, such as impeded drainage and declining groundwater, along with sub-optimal input management and utilization practices, contribute to the lower agricultural productivity in the Rajpura block of the Patiala district, Punjab, compared to other areas of the state. Thus, an attempt has been made to evaluate the land resources of the block to explore the possibilities of diversified agricultural land uses. Site characteristics, limitations, and potentials revealed that the soils of the block belong to land capability subclasses IIs, IIse, IIIse, and IIIsw. Land capability subclass IIs constitutes the maximum area of the block, i.e., about 52.77%, followed by subclass IIIsw (22.89%), IIse (8.65%), and IIIse (1.68%), respectively. The soils of the block belong to land irrigability classes 1, 2sd, and 3sd. Land irrigability class 1 covers the maximum area of the block, i.e., 50.8%, followed by 2sd, which covers 33.51% of the area, while 3sd covers the minimum area (1.68%) of the block. Thus, based on the land capability and irrigability classifications, some management strategies were suggested to ensure better land utilization.  Such strategies include the use of soil and water resources according to their capability instead of following non-scientific practices. The assessment of the Rajpura block's land is a crucial method for assessing the suitability of the soil and suggesting necessary management measures to boost agricultural output, which in turn promotes sustainable land use planning.

Published: December 2024

Present study was conducted in Mohal Khad, Kullu Valley, Himachal Pradesh, investigated the diversity and flower-visiting frequency of insect pollinators on mustard (Brassica campestris). The visual sampling method during the peak bloom of mustards recorded a total of 24 species of insect pollinators from 4 orders, 13 families, and 19 genera, with Hymenoptera being the dominant order, while Coleoptera had the least presence. The Indian honeybee (Apis cerana indica) was the most frequently observed visitor, highlighting its significant role in pollination. Mustards act as an essential foraging source for insect pollinators during early spring in temperate regions, where they bloom earlier than other temperate crops.  The findings help emphasize the importance of mustard cultivation along with the conservation of native species, Apis cerana indica, over exotic ones for sustainable agriculture in the Himalayan region.

Authors: Juyal Sakshi , Gautam Aarushi , Pant Manu
Published: December 2024

The Persian walnut, or English walnut, is one of the most prized walnuts, popular for its timber, medicinal properties, oil, and nuts. Due to its high demand across the globe, walnut cultivation has exponentially grown over the years. Despite having the appropriate climate, the state of Uttarakhand still does not cultivate walnut on a large scale. The alternative to growing walnuts with better quality and high production is through in vitro propagation. The present study was conducted to propagate walnut varieties growing in the Uttarakhand region through direct and indirect organogenesis. The DKW medium proved to be the most effective for nodal explant culture, while the MS medium yielded superior results for callus induction. We also optimized the media by varying the liquid/semisolid medium and plant growth regulator combinations. The genotype from higher altitudes of Uttarakhand was found to respond better to the in vitro treatments. The findings can prove useful in propagating good-quality walnut varieties in Uttarakhand on a large scale.

Published: December 2024

The tribes of the Tons Valley in Uttarakhand, India, prepare Pakhoi, a traditional drink, as the subject of the current study. This drink is known to have therapeutic properties and has potential applications in anti-cancer research. The present study investigates the antiproliferative activity of key compounds found in this drink. Numerous computational tools have assessed the physicochemical properties, pharmacokinetics, drug likeness, and medicinal chemistry of these compounds. SwissADME and Molsoft were utilized to determine properties such as drug likeness scores, especially for Tomentin, which showed the highest score of 1.09. To evaluate anticancer potential, PASS Online software was employed to obtain bioactivity scores; the program reports activity as probable activity (Pa) with values ranging from 0.000 to 1.000 and has a 95% accuracy rate. Pa values greater than 0.7 suggest greater pharmacological action, whereas values less than 0.7 indicate less activity. A variety of drugs regulate ion channel modulators, crucial therapeutic targets that facilitate the passage of charged particles across cell membranes. The next server predicted Haplopine, molecule 4, to be the most bioactive ion channel modulator, with a score of 0.35. Molinspiration: Kinase inhibitors are drugs that selectively inhibit or alter disease-related signaling. Atherospermidine, one of the components in the drink, displayed a bioactivity score of 0.32 as a kinase inhibitor. CLC-Pred was employed to determine the cytotoxicity of major compounds found in the drink for specific cancer cell lines, which shows the value of Pa 0.907 and Pi 0.004. Furthermore, we used PaccMann, a compound that indicates efficacy against cancer cell lines, to determine the IC50 value. It predicted that Narciclasine and Tomentin would be efficient in reducing the proliferation of certain cell lines. Molecular docking was conducted to gain insights into the molecular interaction between the compounds and their specific targets, and the ligand shows the best binding affinity with the protein target CDK4 with -9.7 binding affinity. Swiss Target Prediction helped identify the targets associated with the compounds.  The study provided significant insights into the potential of the tribal drink as an anticancer therapeutic agent.

Therefore, determining the properties of air pollutants is very important for researchers and practitioners working in this field. In this study, the statistical distributions of some air pollutants are determined using the Gumbel, Weibull, generalized Pareto, log-normal, gamma, Rayleigh, and inverse Weibull distributions. The data was obtained from stations Boyabat and Merkez stations in Sinop province in 2017. The Kolmo-Gorov–Smirnov test was used to determine the underlying distributions of the air pollution data. Then we use the root mean square error and coefficient of determination criteria to determine which distribution better fits the air pollution data. Finally, numerical results have shown that the generalized Pareto distribution demonstrates the best overall modeling performance, followed by log-normal and inverse Weibull distributions.

The Shiono–Knight method (SKM) was used to calculate a lateral profile of the depth-averaged velocity and determine the flow rate for a compound channel, both in the presence and absence of emergent vegetation on the floodplains. The SKM is an analytical solution of the Navier–Stokes equations. The effect of vegetation (trees) on flow was simulated using two approaches: with an averaged friction factor and by adding a drag force term in the Navier–Stokes equation. Based on flume and field experiments in compound channels with and without emergent vegetation, values of parameters for the dimensionless eddy viscosity and the secondary flow term were identified using the Monte Carlo sampling technique. The surface of the main channel bed was smooth and made of concrete, whereas the floodplains and all sloping banks were covered by cement mortar composed of terrazzo. Calculations were performed using various models, ap-plied to both laboratory and field data sets. The obtained velocity and flow rate distributions were consistent with observations.

Published: December 2024

A new bounded distribution called the unit Weibull loss distribution has been derived. The corresponding probability density function plots reveal that it can be used to analyze data that exhibit right skewness, left skewness, and approximately symmetric and decreasing shapes. Furthermore, the corresponding hazard rate function plots indicate that it is adequate to fit data that have J, bathtub, and modified bathtub hazard rate shapes. This makes the new distribution suitable for modeling data with complex characteristics. Statistical properties such as the quantile, moments, and moment-generating function are determined. Risk measures, including value-at-risk, tail value-at-risk, and tail variance are also calculated. Furthermore, different principles are derived for the computation of insurance premiums. The parameters of the distribution are estimated using different methods, and their performance is assessed via Monte Carlo simulations. The accuracy of the estimates is thus empirically demonstrated. A quantile regression model with responses following the unit distribution is developed. Applications of the proposed distribution and its corresponding regression model to three insurance data sets are carried out, with their performance compared with other models. The results show that they outperform the other competing models. Thus, the new methodology can serve as an alternative modeling toolkit for modeling insurance data.

Published: December 2024

The insurance market is changing due to new distribution channels, requiring insurers to update their pricing models. We propose a mathematical approach using Bayesian GLM to adjust insurance pricing. Our strategy modifies the pricing model by incorporating distribution channels while utilizing the initial model as a baseline. Bayesian generalized linear models (GLM) enable effective model updates while incorporating existing knowledge. We validated our approach using data from the general insurance sector, comparing it with the traditional approach. Results show that Bayesian GLM outperforms the traditional method in accurately estimating pricing. This superiority highlights its potential as a powerful tool for insurers to remain competitive in a rapidly changing market. Our approach makes a significant mathematical contribution to insurance pricing, allowing insurers to adapt to market conditions and enhance their competitive edge.
The Opone family of distributions. Beyond the power continuous Bernoulli distribution
Authors: Opone Festus C. , Chesneau Christophe
Published: December 2024

Recent developments in applied statistics have given rise to the continuous Bernoulli distribution, a one-parameter distribution with support of [0, 1]. In this paper, we use it for a more general purpose: the creation of a family of distributions. We thus exploit the flexible functionalities of the continuous Bernoulli distribution to enhance the modeling properties of well-referenced distributions. We first focus on the theory of this new family, including the quantiles, expansion of important functions, and moments. Then we exemplify it by considering a special baseline: the Topp–Leone distribution. Thanks to the functional structure of the continuous Bernoulli distribution, we create a new two-parameter distribution with support for [0, 1] that possesses versatile shape capacities. In particular, the corresponding probability density function has left-skewed, N-type and decreasing shapes, and the corresponding hazard rate function has increasing and bathtub shapes, beyond the possibilities of the corresponding functions of the Topp–Leone distribution. Its quantile and moment properties are also examined. We then use our modified Topp–Leone distribution from a statistical perspective. The two parameters are supposed to be unknown and then estimated from proportional-type data with the maximum likelihood method. Two different data sets are considered, and reveal that the modified Topp–Leone distribution can fit them better than popular rival distributions, including the unit-Weibull, unit-Gompertz, and log-weighted exponential distributions. It also outperforms the Topp–Leone and continuous Bernoulli distributions.
Graph models for identifying robot-packable patterns of pallet loading
Authors: Pieńkosz Krzysztof
Published: December 2024

In the logistics processes of trade business, goods delivered from warehouses to retailers are often transported on pallets. The paper concerns the issue of using a robot for automatic palletizing. In order to put an item in a given place on a partially loaded pallet, the robot must have free access to that place, i.e., the place must not be covered. A graph model and a formalized method for determining the sequence of putting goods on a pallet is proposed to avoid such collisions. It is also shown that not every packing pattern can be loaded by a robot. However, some pallet loading approaches have been identified that always guarantee a feasible robot packing.

Published: December 2024

We study a queueing model with disasters, working breakdowns, balking, reneging, and vacations. This is a novel and realistic queueing model that captures the complex dynamics and behaviors of an automatic manufacturing system (AMS) with various uncertainties and disruptions. The system loses all customers when a disaster occurs and repairs start immediately. New customers get slower service during breakdowns. We use matrix methods to find the system’s steady state along with performance measures like the expected number of customers lost, the expected waiting time, and system reliability. We also optimize the system parameters (system capacity, number of servers, service rates) to minimize the cost function using a combined direct search method and quasi-Newton method. Our results can enhance the AMS’s performance, profit, and customer satisfaction.

Published: December 2024

This paper researches differential cooperative games with a coalition structure. To show the payoffs of players, the Owen value for traditional case is extended to the new cooperative model, and its existence and uniqueness are discussed. Furthermore, the relationship between the core and the Owen value is shown. In addition, the sub-game consistency of the Owen value is analyzed that maintains the efficiency of the payoff throughout the game. With the defined characteristic function, it is proved that the Owen value is sub-game consistent. Finally, theoretical results of this paper are applied to solve the problem of cost allocation of environmental governance.

Authors: Babakr Abdullatif Taha , Nour Eldein Mohamed Mahmoud
Published: December 2024

Aim: Breast cancer (BC), a disease in which abnormal breast cells grow out of control and form tumors, is a prevalent life-threatening disease worldwide. Oxidative stress has been implicated in the development and progression of various cancers, including BC. Assessing lipid peroxidation and overall antioxidant status in BC offers valuable information on disease progression, patient prognosis, and the effectiveness of therapeutic options.
Methods: A total of 150 women were categorized into three groups: normal, benign mass, and BC. Participants were selected and evaluated at the cancer clinic; fasting blood samples were collected, and total antioxidant capacity (TAC), oxidized low-density lipoprotein (Ox-LDL), cancer antigen (CA) 15-3, and carcinoembryonic antigen (CEA) were measured. Subsequently, statistical analysis was performed to compare the levels of these parameters in different groups and examine the analytical performance of TAC and Ox-LDL in BC.
Results: In patients with malignancy, the serum level of TAC was significantly decreased compared with the benign group (8.3 U/mL and 16.04 U/mL, respectively) (P < 0.001). Healthy controls exhibited higher levels of TAC (43.4 U/mL). The levels of Ox-LDL in BC were significantly increased in both malignant and benign groups (3,831 pg/mL and 1,234 pg/mL, respectively) compared with normal controls (682 pg/mL) (P < 0.001). CEA and CA15-3 were drastically increased in the BC groups compared with the control group. A significant area under the curve was observed in the receiver operating characteristic (ROC) curve analysis for TAC (0.975, P < 0.001) and Ox-LDL (0.986, P < 0.001).
Conclusions: This study revealed that patients with BC had lower TAC and higher Ox-LDL serum levels, indicating elevated oxidative stress. These levels may serve as promising monitoring parameters in BC.

Published: December 2024

La hernia de hiato es una patología frecuente con sintomatología leve en la mayoría de los casos. Las complicaciones derivadas de ella son infrecuentes, requiriendo cirugía urgente el 1-2% de los casos. Se expone el caso clínico de una hernia de hiato tipo III gigante incarcerada, que en ese contexto sufre una perforación gástrica intratorácica. Por este motivo requiere intervención quirúrgica urgente, realizando una gastrectomía total con anastomosis esófagoyeyunal. Se añaden imágenes de la tomografía y del hallazgo intraoperatorio. La incarceración de la hernia de hiato suele presentar una exacerbación de la sintomatología. De este modo, puede progresar desde la inflamación hasta la isquemia transmural gástrica con necrosis asociada. Aunque la técnica quirúrgica en la cirugía urgente de la hernia de hiato no está claramente definida, en algunos casos con isquemia y necrosis asociada, la gastrectomía parcial o segmentaria podría ser suficiente. Sin embargo, en casos de afectación isquémica y necrosis extensas, como sucedió en el caso presentado, puede ser necesaria la gastrectomía total.
