Authors: Saxena Aishwarya , Singh Anushi , M. Govindaraj
Published: September 2023

Customer churn, the loss of customers to a business, is a significant challenge in the banking industry. Retaining existing customers is crucial for banks to maintain profitability and sustain growth. This paper focuses on analyzing customer churn in the banking sector. The study utilizes data mining and predictive analytics techniques to analyse customer behaviour, identify churn patterns, and develop predictive models. This research uses a data mining technique called Gaussian mixture model clustering-based adaptive support vector machine (GMM-ASVM) to forecast customer loss in the banking industry. By analyzing consumer competency and loyalty to the banking industry using GMM, this study predicts customer behaviour using a clustering approach. An accuracy of 98% was attained while classifying the clustering results using ASVM. This study gives bank administrators the ability to analyse the behaviour of their clients, which may trigger appropriate tactics based on engaging quality and increase appropriate actions of administrator capacities in interactions with customers.

Authors: Vijay G. S. , Sharma Meenakshi , Khanna Roma
Published: September 2023

The creation of methods and models that can learn and make predictions or judgments based on such learning is artificial intelligence (AI). By combining an AI-driven intrusion detection system (IDS) with the BAT optimization method and a Deep Convolutional Neural Network (DCNN), we provide a revolutionary strategy to the revolutionize network management. Utilizing the advantages of deep learning and BAT optimization, the goal is to increase the efficiency of intrusion detection in the network management. Here, the classification effectiveness of the DCNN is increased by using the BAT optimization strategy. The suggested framework combines a DCNN model, which is excellent in pattern data collection, pre-processing by using normalization, and prediction tasks, with the BAT Optimized with Deep Convolutional Neural Network (BATO-DCNN) method, recognized for its capacity to identify optimum solutions in the challenging search spaces. The suggested method effectively tunes the DCNN using BAT optimization, leading to the better convergence and accuracy. The results of the research show that the recommended methodology performs better than traditional approaches in terms of accuracy, precision, F1-score, and recall measures. The results of this study support the current research in the area of network security and open the door for improved network management systems.

Authors: Wadesango Newman , Jori Admire K. , Lovemore Sitsha
Published: September 2023

The purpose of this desktop study was to examine the efficacy of e-government technologies and the obstacles to their efficient use. The researchers assessed how well e-government affected service delivery, how it might result in cost savings and the advantages and difficulties of adopting and using it. The study also looked at the advantages of using e-government to investigate this. E-efficiency in providing services was demonstrated by greater citizen involvement and interaction with the local government, increased openness and accountability, and cost savings. The study revealed that the use of e-government improves traditional methods of conducting business and providing services while also enabling access to information and services online, reducing the need for rework, increasing transparency and accountability, and encouraging citizen participation. The ineffective use of e-government in local authorities was hampered by a lack of funding, inadequate enabling infrastructure, low ICT literacy levels, and the digital divide, among other factors. It was evidenced in this study, that e-procurement leads to cost savings, thus it affects cost reduction strategies positively. Thus, e-procurement reduces inventory costs.
Enhancing diagnostic accuracy for unidentified primary tumors with remora-optimized novel machine learning approach
Authors: Singh Ashok Kumar , Kumar Pradeep , Sapcota Samir
Published: September 2023

Unidentified originating Tumors (UPT) are a kind of cancer where the originating location of the disease is still unclear, despite cancer cells throughout the body. In other words, even when malignant cells are present, medical professionals are unable to pinpoint the precise organ or tissue where the disease first started. The medical industry offers a big opportunity for Machine Learning (ML) to contribute significantly to illness prediction. One of the primary health challenges that each country faces is the tumor or cancer. In this study, we create a Remora Optimized Gated Recurrent Neural Network (RO-GRNN) to predict UPTs. The proposed approach consists of three stages: pre-processing, classification, and optimization. At first, we classified the UPT using the datasets given in the UCI ML library. The acquired Magnetic Resonance Imaging (MRI)/ Computed Tomography (CT) images will therefore have noise, lowering the efficiency with which classification may be accomplished. Pre-processing techniques like filtering and contrast augmentation could be used to eliminate unwanted noise from the offered images. The Gated Recurrent Neural Network (GRNN) and the Remora Optimization Algorithm (ROA) were both used in the development of the suggested classifier. Multiple optimization procedures, including basic and parametric optimization, take advantage of the ROA inside the GRNN. The proposed approach is employed in Origin Pro, and F1-Measure, recall, precision, and accuracy are some of the performance matrices that are used to evaluate effectiveness. The suggested approach is contrasted with the current ANN, SVM, and LSTM approaches. This research revealed that the proposed method has a 98% accuracy rate for UPT prediction.

Authors: Singh Naveen Kumar , Gupta Rahul , Sahu Satyaapir
Published: September 2023

Early detection of lung cancer nodules, which is often dependent on a tomography scan filmic examination, greatly increases the probability of survival. Earlier tumor detection reduces lung cancer mortality by increasing the likelihood of successful therapy. Traditionally, radiologists have analyzed medical pictures for signs of lung cancer using a laborious and inaccurate systematic approach. The confidentiality and integrity of medical data have become a serious challenge for healthcare applications as a result of the tremendous improvement in the transmission of medical data in the healthcare sector. This research makes use of computational intelligence methods. In this research, a brand-new Enhanced vortex search algorithm optimized Support Vector Machine (EVSAO-SVM) is developed for detection and classification. Preprocessing using the Gaussian Filter, segmentation with Otsu thresholding, feature extraction with local binary patterns (LPB), and classification and prediction with the EVSAO-SVM are the processes that are simulated. Regarding performance criteria including accuracy, sensitivity, specificity, and F1-measure, this study indicates the suggested framework's superiority over the traditional approaches. The results of the tests conducted demonstrate that the suggested model can reach up to 95.42 percent sensitivity, 96.24 percent accuracy, 98.92 percent specificity, and 94.26 percent F1 measure.

Published: September 2023

Concrete is substantially a prerequisite material being used but as the year’s pass, the concrete structures due to external load application might be subjected to the inevitable crack formation that can degrade their durability and strength. The addition of bacteria and the supplementary calcium source creates a pervious layer over concrete fissures similar to calcite precipitation in sealing pores and micro-cracks in the concrete. This review exemplifies the usage of several species of calcite-precipitating, alkali-resistant Bacillus bacteria as crack healing agents and nutrients added for bacteria sustainability in the concrete and mortar at diverse age periods. Various strategies have been proposed to endow self-healing in concrete in past decades. This review summarizes the effect of micro-capsules, hydrogels, cellulose fiber, polymers, mineral admixtures and bacteria type when employed in cementitious materials. This study exuviates light on the advantages of bio minerals produced via bacteria metabolism that improves mechanical properties, durability parameters and microstructure behaviour. It can be summarized that the inclusion of bacteria in concrete and mortar improves its properties resulting in crack healing, making it more sustainable and reducing maintenance cost. Furthermore, research can be a promising investigation into the longevity of the bacteria for its extensive practical outcome-based application.

Authors: Jyothi S. Renuka , Verma Shikhar , Gupta Prerana , Ramakant
Published: September 2023

Sleep disorders (SD), such as obstructive sleep apnea (OSA), restless legs syndrome (RLS), and others, may affect anybody, regardless of health or the presence of chronic problems like Multiple Sclerosis (MS). People with Multiple Sclerosis (PwMS) and a community population from So Paulo, Brazil, were compared for issues with sleep, depression, fatigue, and the chronotype. Participants in the PwMS trial were not the same as those in the So Paulo Epidemiologic Sleep (SPES) study. Analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) tests were used to investigate the sleep questionnaire responses to determine the impact of various factors. Covariates are factors that include age, sex, and activity. The results of the sleep surveys with the Expanded Disability Status Scale (EDSS) have been analyzed utilizing the Pearson correlation test (PCT). Propensity score matching additionally decreased predict bias for differences between the two groups. The tools for the analysis were Stata 14 with IBM SPSS Statistics for Windows, version 22.0. By comparing the PwMS, the Episono group (EG) slept less soundly and felt more sleepy when they woke up. In the Episono group, OSA and RLS were more common. The two groups' choices for the morning and the middle did not differ according to chronotype. The EDSS and sleep problems did not correlate. PwMS described being completely worn out. Sleep issues were less common, although disease-modifying drug-treated weariness was more common in PwMS than in a sample of So Paulo city residents. There was no difference in chronotype. The immunomodulatory medications often used for MS may have affected these results.

Status prawny zapisobiercy windykacyjnego (zagadnienia wybrane)
Authors: Witczak Hanna
Published: September 2023

Wprowadzenie do polskiego systemu prawnego zapisu windykacyjnego jest kolejnym etapem reformy prawa spadkowego. Stanowiący wyjątek od zasady sukcesji uniwersalnej legatum per vindicationem wywołuje skutki o charakterze rzeczowym, tzn. że w chwili otwarcia spadku przeznaczone w zapisie dla uprawnionego określone prawo przechodzi na zapisobiercę. Nabycie zapisu z chwilą otwarcia spadku ma, tak jak nabycie spadku, charakter tymczasowy. Zapisobiercy windykacyjnemu przysługuje uprawnienie do złożenia oświadczenia o przyjęciu lub o odrzuceniu zapisu. Treścią oświadczenia zapisobiercy windykacyjnego może być tylko przyjęcie albo odrzucenie zapisu. Odmiennie niż ma to miejsce w przypadku spadkobiercy, zapisobierca windykacyjny nie ma możliwości poprzez złożenie oświadczenia o przyjęciu spadku o odpowiedniej treści (przyjęcie wprost lub z dobrodziejstwem inwentarza), wpłynąć na zakres swojej odpowiedzialności za długi spadkowe. Zakres odpowiedzialności zapisobiercy za długi spadkowe został ograniczony ustawowo do wartości przedmiotu zapisu windykacyjnego według stanu i cen z chwili otwarcia spadku - ograniczenie pro viribus patrimonii. Do chwili działu spadku zapisobiercy windykacyjni wraz ze spadkobiercami ponoszą solidarną odpowiedzialność za długi spadkowe, natomiast od chwili działu spadku spadkobiercy i zapisobiercy windykacyjni ponoszą odpowiedzialność za długi spadkowe proporcjonalnie do wartości otrzymanych przysporzeń. Mechanizm rozłożenia ciężaru długów spadkowych na te dwie kategorie podmiotów tłumaczy się tym, że - materialnie rzecz biorąc - zapis windykacyjny jest powołaniem do spadku w zakresie jednego przedmiotu, a nie zapisem.

Authors: Larsman Pernilla , Ulfdotter Samuelsson Amanda , Räisänen Christine , Rapp Ricciardi Max , Grill Martin
Published: September 2023

BACKGROUND: The construction industry is heavily affected by occupational accidents, and it is important to investigate how leadership behaviors promoting safety on construction sites are fostered among construction-site managers. OBJECTIVE: The overall aim of this study was to investigate how safety-leadership behaviors can be developed in the construction industry, specifically focusing on managerial role modeling. METHODS: A two-wave longitudinal cohort study with approximately four months between measurement occasions was conducted among construction-site supervisors in Sweden (n = 51). Supervisors’ ratings of their site managers’ and their own generic and safety-specific contingent reward (CR) leadership behaviors were obtained by means of questionnaires. Cross-lagged panel models were tested within a path model framework to test the hypothesis that site managers’ leadership behaviors prospectively influence supervisors’ leadership behaviors. RESULTS: Site managers’ CR behaviors prospectively influenced supervisors’ CR behaviors, both generic CR behaviors (β= 0.29, p = 0.01) and safety-specific CR behaviors (β= 0.22, p = 0.04). For safety-specific CR behaviors, a reversed effect (β= 0.26, p = 0.03) was also found, implying that supervisors’ behaviors prospectively influenced site managers’ behaviors. CONCLUSION: Site managers act as role models for supervisors when it comes to developing safety-leadership behaviors on construction sites. The results also indicate that site managers are influenced by their subordinate supervisors’ safety-leadership behaviors. Hence, there seems to be reciprocal interaction between site managers and supervisors in which they influence each other and together shape safety-leadership practices at their construction sites.
The Comparison of Traverses Adjusted by Non-Rigorous and Rigorous Methods of Adjustment
Authors: Oranyelu Olisemeka
Published: September 2023

In geodetic surveying, the adjustment of traverses has long been a topic of discussion and analysis. Scholars have posited that the adjustment of traverses can be approached either non-rigorously through methods such as the Bowditch or Transit techniques, or rigorously through more advanced methods. Empirical evidence has consistently indicated that the rigorous adjustment of surveying data yields results of superior accuracy compared to non-rigorous methodologies.

This research endeavour is dedicated to a comprehensive comparison of traverse adjustments within a specified sector of the Federal University of Technology Owerri. The study focuses specifically on a closed loop traverse comprising twelve station points, characterized by inter-point distances spanning the range of 200 meters to 300 meters. The primary instrument employed for this traverse was the Total Station. The traverse underwent scrutiny to ensure closure, and it was found to be well within acceptable limits. Subsequent computations involved both non-rigorous techniques, specifically the Bowditch and Transit rules implemented within an Excel platform, and rigorous methodologies, specifically the employment of the Adjust software based on the least squares’ principle.

The basis for comparison in this study primarily revolves around the computed standard deviation of the adjusted parameters, along with a meticulous assessment of the disparities in the individual coordinates derived from non-rigorous approaches. Significantly, the Transit method emerges as the superior choice, demonstrating a greater degree of accuracy when juxtaposed with the Bowditch method. Consequently, this research underscores the 

recommendation for the adoption of the Transit method over the Bowditch approach in the context of traverse adjustments.

The concept of the evolutionary synthesis of complex control systems, which are the subject of study in classical control theory, and the concept of the evolutionary synthesis of intelligent fault-tolerant control systems, which are the result of the intellectualization of traditional complex control systems in order to solve problems of rational decision-making, the difference between these concepts from each other, are considered. At the same time, the intellectualization of complex systems should be considered as a positive type of development of control systems, which significantly facilitates making the right decisions, since the decision mechanisms in them are similar to the mechanisms used by human intelligence. The main feature of these types of complex control systems is the inability to unambiguously adequately describe the complex control system under study using classical mathematical methods. Mathematical models are suitable only for describing some moments, the most general properties and patterns, and there is always a wide range of issues and problems that cannot be described on the basis of existing formal methods. The methodology of evolutionary synthesis, combining the best achievements of classical control theory and the theory of artificial intelligence, is designed to help solve these problems.

The paper analyzes an experiment on two-dimensional (in azimuth and elevation) noise suppression in an active radar in the decimeter wavelength range. The radar includes an adaptive antenna array, the canvas of which has a rectangular topology. As jammers, a continuous tone generator is used, as well as a phase-shift keyed signal generator – a Barker code of length 11. In both cases, the interference can be considered narrowband. As a useful signal (reflected from the target), a Barker code of length 11, generated by the simulator, was used. The noise suppression was carried out by the power vector method, as well as by the method of direct inversion of the noise correlation matrix. The case of a short sample when evaluating the correlation matrix is considered separately, as the most interesting for practice in conditions of limited computing resources of digital signal processors. A set of scenarios is considered both in azimuth and in elevation. In all scenarios, there was one interference and one useful signal. For each of them, the estimation of losses in relation to signal-tonoise, the interference suppression coefficient was performed, and the directivity diagrams of the adaptive antenna array were formed. The processing of the experimental data showed the high efficiency of the power vector method. In all scenarios, interference is suppressed almost to the level of thermal noise.

Knowledge about the age dynamics of physical development indicators of operational level officers has significant importance in the context of scientific research and practical activities of military personnel. The aim is to determine the age dynamics of physical development indicators among operational level officers in the first and second periods of mature age. Material and methods. We used anthropometric research methods, including measuring body length, body weight, and girth sizes of different body parts. Also, we used bioelectrical impedance analysis to determine body composition, including fat amount, muscle mass, water content, and other parameters. In addition, we measured skin-fat folds to assess the distribution of fat tissue in different parts of the body. Using the obtained results, we performed mathematical analysis, such as descriptive statistics and significance criteria. Parametric criteria were used to compare indicators of physical development between age groups of officers, too. Research results. We found out that the age indicator between the studied groups had a statistically significant difference (p <0.05). However, we found the absence of statistically significant differences (p >0.05) in anthropometric characteristics, such as body length, body weight, body mass index, total fat content and its distribution in individual parts of the body, total water content, muscle weight and bone mass between the officer groups. But also, we found that the content of visceral fat in officers of the second period of adulthood was statistically significantly higher (p <0.05), which indicates the presence of age-related changes in the distribution of visceral fat in the body. Comparison of the average group results of five skin-fat folds in the studied groups of officers did not reveal statistically significant differences (p >0.05). These results indicate that the distribution of fat mass in officers of the operational level of the first and second periods of adulthood may be similar and the age factor does not significantly affect this aspect of anthropometry. We established the absence of a statistically significant (p >0.05) difference in girth measurements of various body parts (neck, shoulder, wrist, chest, waist, pelvis, hip) between operational level officers of both age groups. This means that the indicators of physical development of operational-level servicemen remain stable during the first and second periods of adulthood. Conclusion. The obtained results of the study indicate the absence of a statistically significant (p >0.05) difference between the vast majority of the studied indicators. Also, that the physical development of operational level officers of both age groups remains stable, except for certain aspects such as visceral fat content.

Power in University Archives: Imperialism and Disparities in Nigeria and the United States
Authors: Cermak Robert
Published: September 2023

This article examines the structural disparities between the archives at the University of Nigeria Nsukka (UNN) and Michigan State University (MSU). While Nigerian archivists work to preserve their institutions’ local content, they must contend with cultural and infrastructural constraints foreign to their American counterparts. To elucidate these differences, this analysis builds upon Stoler’s ‘archival turn’ framework which shifts the gaze on archives to consider them as subjects of inquiry rather than mere sources of data. Reflecting on my own experience working with physical archives at UNN and MSU, along with digital artifacts from these institutions’ websites, I analyze the contents and accessibility of hardcopy and digital collections at both universities. In conclusion, I argue that the ongoing and uneven footprint of imperialism, both socio-cultural and infrastructural, results in an unequal distribution of Trouillot's ‘archival power’ amongst global institutions like UNN and MSU. Additionally, I highlight means by which some Nigerian scholars have contested imperialism to reclaim ownership over their own archival contents and narratives.

Published: September 2023

Introdução: Na Diabetes Mellitus Tipo 1 (DM1) ocorre uma destruição maciça das células beta do pâncreas, produtoras de insulina, acarretando redução desse hormônio. Assim, é necessária administração exógena de insulina para controle diário da glicemia. No entanto, o controle é difícil, predispondo os pacientes acometidos pela doença a problemas na saúde pelo descontrole glicêmico. Por isso é de grande importância o estudo dos mecanismos imunológicos envolvidos na patogênese dessa doença. Objetivo: Evidenciar os mecanismos imunológicos envolvidos na patogênese da DM1. Método: Trata-se de uma revisão integrativa, em que os estudos foram buscados nas bases de dados PubMed e Scielo pelos descritores. Após a seleção, tais estudos foram avaliados e submetidos aos critérios de exclusão pelos pesquisadores, restando 20 artigos para a realização do estudo. Resultados: Os locus do MHC II são os mais correlacionados com o desenvolvimento de DM1. Os locus estudados que apresentam correlação com a doença são DP, DQ e DR, responsáveis por expressar a proteína da membrana. Pacientes com genótipos específicos presentam maior chance de desenvolvimento da doença. Essas alterações genéticas podem ser de origem hereditária, sendo mais relacionadas com irmão e pai afetados do que com mãe afetada. Além disso, Células Treg e células TCD8+ fazem parte do fator imunológico que exerce influência sobre o desenvolvimento da DM1, porque há uma modificação das funções dessas células, criando um fator autoimune. Há uma certa limitação em relação a esses estudos, já que não se pode afirmar nada de maneira assertiva, uma vez que os mecanismos genéticos e imunológicos, abordando os biomarcadores, ainda não são muito elucidados. Conclusão: Há fatores imunológicos genéticos e celulares envolvidos no desenvolvimento de DM1. Entretanto, são necessários estudos mais aprofundados para compreender como essas ferramentas poderiam ser utilizadas no rastreio e mapeamento dos pacientes com predisposição a DM1.

У статті проведений критичний аналіз сучасних даних щодо парвовірусного ентериту собак. На сьогоднішній день захворювання собак цим вірозом викликає занепокоєння ветеринарних лікарів-практиків у зв’язку з його широким розповсюдженням на території України та в цілому світі. Додаткові ризики розповсюдження інфекції створює велика кількість безпритульних собак, серед яких не проводяться діагностичні та профілактичні заходи по боротьбы з парвовірусним ентеритом. Збудником парвовірусного ентериту собак є невеликий за розмірами вірус з родини Parvoviridae. Джерелом інфекції виступають хворі собаки та вірусоносії. Крім собак хвороба складає небезпеку для єнотовидних собак, лисиць, куниць. Найбільш сприйнятливі до захворювання молоді собаки віком від двох до п’ятнадцяти тижнів. Собаки віком понад три роки в більшості випадків не хворіють на парвовірусний ентерит. Тварина заражається навіть при короткотривалому контакті з інфікованою твариною або вірусовмісним матеріалом. Існують фактори, що впливають на зараження собак, такі як природна резистентність організму, наявність колострального імунітету, стать вік, порода, тощо. Виділяють наступні форми захворювання: серцеву, кишкову, абортивну, змішану, що проявляється ураженням певних систем організму собаки та проявом відповідних клінічних і патолого-анатомічних змін. На цей час розроблено багато методів діагностики парвовірусного ентериту, проте у зв’язку з мутацією збудника, вони потребують постійного удосконалення. Збудник парвовірусного ентериту собак стійкий до впливу факторів зовнішнього середовища, що створює додаткові проблеми при проведенні дезінфекції. Наявність великої кількості засобів специфічної профілактики не завжди ефективно призводить до зниження показника захворювання тварин, тому що ці засоби можуть використовуватися без урахування епізоотичної ситуації, особливостей організму собак, віку тварин тощо.

Свинарство є широко представленою галуззю тваринництва в Україні. Однак, впродовж останніх років відмічається стійка тенденція до зниження як товарного, так і племінного поголів’я свиней в господарствах усіх форм власності різних виробничих потужностей. Відповідно, надзвичайної актуальності набуває дотримання заходів біобезпеки в господарствах для недопущення спалахів серед поголів'я заразних захворювань. Запорукою недопущення на територію свинарських господарств біологічних небезпек будь-якого характеру є, крім високотехнологічного обладнання, наявність професійного персоналу для виконання технологічних операцій. Провівши аналіз існуючого комплексу запроваджених заходів біобезпеки в одному зі свинарських господарств Чернівецької області було встановлено, що саме «людський фактор» є слабкою ланкою в системі заходів біобезпеки господарства. В господарстві взято під контроль можливість потрапляння біологічних агентів з кормами, відрегульована система вентиляції виробничих приміщень в усіх вирощуваних вікових групах тварин. На територію комплексу не допускають сторонніх осіб не пов’язаних безпосередньо з виробничим процесом, однак встановлено порушення режимів перебування в «чистій» та «брудній» зонах, виробничих приміщеннях окремих працівників комплексу. В господарстві налагоджена чітка система заходів для недопущення потрапляння збудників на територію тваринницького господарства зовні, що наразі дозволяє господарству позиціонуватися як вільне від основних специфічних патогенів. За міжнародними стандартами дане господарство має статус SPF (червоний рівень). В господарстві функціонує та неухильно дотримується чітка схема вакцинопрофілактики, що також додатково слугує одним із важливих чинників підтримання біобезпеки. Вакцинопрофілактикою охоплено різновікові групи тварин. Особливий акцент здійснюється на вакцинації поросних свиноматок. Відповідно, ефективними засобами є максимальне запровадження європейських технологій виробництва свинини, де вплив людського фактору мінімізовано.

Прогресивний розвиток тваринницької галузі в Україні базується на декількох основних засадах, однією з яких є відтворення. Ефективне відтворення основного стада є гарантією стійкого розвитку як кожного окремо взятого тваринницького господарства, так і галузі загалом. За сталої кількості поголів’я в господарстві ремонт складає близько 25%, а при нарощуванні поголів’я ‒ від 30% до 40%. Відомо досить велике коло причин зниження, а інколи і повного припинення відтворної здатності корів. Для установлення конкретних причин актуальним є розробка ефективних методик прогнозування та діагностики гінекологічних патологій корів, особливо у транзитному періоді. Метою дослідження було дослідження кореляції між зміною окремих біохімічних показників крові корів на 30‒60 добі після отелу та відтворною здатністю самок. Дослідження проводились протягом 2021-2023 років у господарствах Cумської області із безприв’язним типом утримання. Продуктивність при цьому була на рівні 7200‒7500. Кров для біохімічних досліджень відбирали із підхвостової вени в період від 30 до 60 днів після отелу. В подальшому проводили біохімічні дослідження за загальноприйнятими методиками. Отриманий цифровий матеріал оброблено методами варіаційної статистики з використанням SPSS Data editor 17.0 version. Встановлено напружений білковий обмін у корів в післяотельний період, що характеризувався верхньою межею рівня загального білка ‒ 86,0±2,58 г/л та білковим коефіцієнтом ‒ 0,76±0,037 од. Зареєстровано зниження рівня глобулінів у 1,2 рази у неплідних корів, що супроводжується зменшення білкового коефіцієнту у 1,24 рази. У неплідних корів характерним було підвищення аспаратамінотрансферази та лужної фосфатази у 1,37 (р≤0,01) і 1,17 рази (р≤0,05) відповідно. Проте у корів першої групи (фертильні тварини) зареєстровано тенденцію підвищення коефіцієнта де Рітіса у 1,29 рази та зниження рівня азоту сечовини крові у 1,19 рази порівняно із неплідними коровами. Важливим прогностичним критерієм є вищий у 1,13 рази рівня вітаміну Е (12,8%) у фертильних корів. Діагностовано гіпокальціємію та гіперфосфоремію у крові неплідних корів із кліренсом із здоровими у 1,18 рази (р≤0,05), що спричиняло тенденцію до зниження Са/Р співвідношення. Зміни біохімічних показників у крові тварин обох підгруп усіх інших мікро та макромінералів вірогідно не відрізнялись, за виключенням цинку, рівень якого у крові неплідних тварин був вищий у 1,3 рази (р≤0,05).

With the recent legalization of cannabis in Canada, there is an urgent need for information about its effects on Indigenous populations due to the impact of cannabis on the mental health of Indigenous Peoples in Canada being largely unknown. Using the guiding principles of Etuaptmumk (Two-Eyed Seeing), Sharing Circles were held to hear the needs and experiences of Indigenous People in relation to their mental health and cannabis use. From these engagements and using gender-based and distinctions-based analysis, four recommendations were developed for academic institutions, medical regulatory authorities and health and social care providers (HSCPs) to consider when caring for Indigenous People living with mental health issues. The findings point to the disconnection between recent research on medical cannabis and its availability to Indigenous People through accessible mediums, HSCPs, and the lack of cultural safety in health and social services. The four recommendations provided are helpful to both educate frontline HSCPs about the needs and experiences of Indigenous People and improve access to current information and best practices for Indigenous People who use cannabis for mental health from the regulatory and representation perspective.

Después de casi siete años de actividad de los sexenios autodenominados como “del cambio”, es conveniente efectuar un análisis de la política laboral que han llevado a cabo y que previsiblemente podría ayudar a la solución del crítico problema del desempleo en México. En este artículo se analiza especialmente el Programa del Primer Empleo, tanto desde sus perspectivas teóricas como de sus adecuaciones prácticas, así como de otros tres programas de menor alcance que revelan una sustitución de la política laboral por una política de apoyo social.
