Poultry is one of the most intensive and dynamic sectors of agricultural production, it is an avantgarde industry not only in animal husbandry, but also in all agriculture. However, various infectious diseases do not bypass this industry. The problems of industrial and private poultry farming are such diseases of poultry as pasteurellosis, colibacteriosis, salmonellosis, staphyllococcosis. The development of new treatments for these diseases is an urgent trend in modern veterinary medicine, which includes preclinical trials, and in particular the assessment of the tolerability of the drug. We conducted studies of the combined antibacterial drug Dithrim® OR. It has been established that oral use of Ditrim® OR in a therapeutic and three-fold therapeutic dose does not have a pronounced pathological effect on the body of broiler chickens. During the experiment, no bird death or clinical signs of intoxication (depression, diarrhea, etc.) were noted. The bird was active and well-fed. The live weight of chickens in the experimental groups did not significantly differ from the weight of the bird that was kept in the control group. It has been found that the preparation at the specified doses, duration and method of use does not adversely affect the body of broiler chickens and is well tolerated by animals.

The article presents morphological changes of the cornea in small domestic animals during crosslinking. The research was carried out on the basis of the Department of Anatomy and Histology of Animals named after Professor A. F. Klimov, as well as the Center for Veterinary Ophthalmology of Dr. Shilkin A.G. Morphological studies were performed in the Department of Pathomorphology of the FSAU «MNTC «Eye Microsurgery» named after Academician S. N. Fedorov». The objects of the study were selected cats (n=10) aged 4 to 6 years and dogs (n=10) aged 4 to 6 years of the Yorkshire Terrier breed (n=5) and Chihuahua (n=5), admitted to the «Center of Veterinary Ophthalmology of Dr. A. Shilkin.G.», euthanized as a result of received polytrauma incompatible with life. Analysis of the data obtained allowed us to conclude that corneal collagen crosslinking affects changes in the morpho-functional features of the corneal stroma. The data on changes in the anterior layers of the stroma, which are expressed by a compact packing of fibers without signs of edema, as well as a demarcation line separating the impact area from the indifferent zone, are scientifically substantiated. The results obtained are basic in the development of new methods of therapeutic strategy and tactics in the treat-ment of animals with keratopathies of various genesis.

The article presents a comparative micromorphological characterization of dental hard tissues in the domestic dog depending on the generation (deciduous and permanent). The research was conducted at the veterinary clinic «Zoovetcenter», Khanty-Mansiysk Autonomous Okrug, Surgut, at the Department of «Animal Diseases and Food Safety» of Saratov State University of Genetics, Biotechnology and Engineering by N. I. Vavilov and the Department of Anatomy and Histology of Animals named after Professor A. F. Klimov of Moscow State Academy of Veterinary Medicine and Biotechnology – MVA by K. I. Skryabin. The object of the study was a domestic dog (n=30) aged from 5 months to 2 years. The material for the study were extemporized teeth (n=50) of different generation. We used a complex methodological approach, including: fabrication of tooth slides according to the generally accepted technique with subsequent staining with histological dyes, light microscopy and micromorphometry. The study of the obtained tooth slides showed differences in the structural organization of dental hard tissues at different stages of odontogenesis in the domestic dog (deciduous and permanent generation of teeth). The percentage ratio of dental hard tissues in relation to the pulp chamber was revealed. The peculiarities of the organization of the root system depending on the age features have been established. The obtained results can be used in the identification of age and dental tissues, and are basic in the improvement of old and development of new methods of differential diagnostics of dentopathologies in small domestic animals.

Otitis externa is a common pathological condition of small pets requiring antimicrobial therapy. Widespread unjustified use of antibiotics exacerbates the existing problem of antibiotic resistance, and the number of isolates with multidrug resistance (MDR) is increasing. In this regard, an actual task is to search and evaluate alternative methods of antimicrobial therapy, for example, bacteriophages. In this study, the antibacterial activity of an experimental bacteriophage-based drug was evaluated against current participants in the etiopathogenesis of otitis externa in dogs and cats: Staphylococcus pseudintermedius, Staphylococcus aureus, Streptococcus pyogenes, Staphylococcus schleiferi subsp. Coagulans, Staphylococcus hyicus, Pseudomonas aeruginosa, Escherichia coli, Streptococcus canis, Enterococcus faecalis. The bacteriophage-based drug showed expressed antibacterial efficacy in vitro. When diluted 128 times, the cocktail of bacteriophages stably lysed test cultures of bacteria. There is a need for constant search and expansion of the number of virulent strains of bacteriophages to create an experimental means for the treatment of external otitis externa in dogs and cats, nevertheless, due to the positive results of the studies conducted, the actual potential of bacteriophages as an alternative to antibiotic therapy for pathologies of the external auditory canal in small pets is confirmed.

Gray rats occupy a significant share in the number of synanthropes living next to humans. The fight against them is difficult, due to their high adaptability, as well as the risk of poisoning of non-target wild and domestic animals. Insufficiently organized deratization measures lead to an increase in the number of rodent populations and their settlement of new adjacent territories. Gray rats belong to the species of mouse-like rodents resistant to the action of many factors, including developing resistance to the effects of rodenticidal baits based on anticoagulants. Experimental studies have shown that the eating of at least 50 % of the daily requirement of baits containing 0,005 and 0,0025 % of the concentration of DV bromadiolone by gray rats during one day can cause 1 % death. When analyzing the results obtained when feeding baits, it was found that for the death of gray rats, the maximum dose was 100 mg/ kg, and the minimum was 6,88 mg/kg. Gray rats in conditions of free access to food and bait can consume up to 0,7 g of rodenticidal agent to achieve a lethal effect, but it will be enough for individuals to eat about 40 g for this.

Clinical and subclinical forms of mastitis are widespread in dairy cows and cause premature slaughter of animals due to lack of milk, agalactia, atrophy and hardening of the udder. The incidence of mastitis in dairy cows averages about 25 %, but the manifest form of mastitis occurs in 50 % of lactating cows. Culling large numbers of dairy cows can have a negative impact on production profits. The early slaughter of dairy cows is influenced by various factors, mainly violations of veterinary and zootechnical husbandry rules. It should be noted that veterinary measures for the prevention and treatment of mastitis are not always effective. Statistics from the veterinary department show that the average age of Russian dairy cows is 2,7 lactations. The decisive role in the etiology of mastitis depends on three interrelated factors (infectious agent, protective properties of the macroorganism and environmental influences). At the onset of the disease, a sterile inflammatory process occurs, which is then complicated by the microbial community. Opportunistic microorganisms accumulate in the tip of the nipple and the nipple canals, penetrate the nipple and suprapapillary cisterns and cause an infectious process. Inflammatory processes in the intestines, organs of the reproductive system, etc. can also lead to infection of the mammary glands. The part of the udder that produces the most milk is most often affected. Microorganisms penetrate the mammary gland in three ways (mammary, hematogenous and lymphatic). During the inflammatory process, under the influence of microorganisms, milk proteins are destroyed, the pH of the environment changes, and clots and flakes appear. Subsequent changes depend on the severity of the inflammatory process. If timely measures are taken, the physiological processes and structure of the breast tissue can be restored, otherwise atrophy of one lobe (quarter) of the mammary gland will occur. The clinical symptoms of subclinical mastitis are unknown. Serous-catarrhal exudate appears in the alveoli, the components of which are lymphocytes, plasma cells and multinucleated cells. The protein composition of milk undergoes significant changes, which are characterized by a decrease in the content of total protein and casein, an increase in the concentration of whey protein, an increase in the alkalinity of milk, and an increase in the number of somatic cells. If cows with subclinical mastitis are left untreated, they resolve spontaneously in 12–20 % of cases and develop clinical signs in 15–20 %.

The aim of the study is to investigate the effectiveness of the own treatment regimen for bovine teleziosis in Aberdeen Angus calves. The experience involved 20 calf heads aged 8 months of the Aberdeen Angus breed with a confirmed diagnosis of bovine teleziosis (10 heads with Thelazia gulosa, 10 heads with Thelazia rhodesi). The insecticidal preparation "Entomazan" was applied topically to animals by bathing with a prepared 0.2 % emulsion one-time after confirming the diagnosis of teleziosis by flushing from the conjunctival cavities and the tear canal, the agent for treating cattle of a patient with self-developed teleziosis was applied directly to the conjunctival cavities of the affected eyes of the calves in the proposed dosage – 1 ml in each eye daily, one-time, within 10 days. The efficacy of the therapy was monitored on Days 2, 5 and 10. Results and discussion. The developed treatment regimen for bovine teleziosis was 100 % effective in clinical trials. On the 5th day after the treatment, no individuals of telezia were found in the control washes. Insecticidal efficacy of the regimen is maintained for 10 days. This scheme has the advantage that the patented agent for the treatment of cattle with teleziosis contains both the main antiparasitic component – levomesol, having 100 % efficacy against nematodes Thelazia gulosa and Thelazia rhodesi, and anti-inflammatory – dexamethasone 15, antibacterial – florfenicol, locally analgesic – 0.5 % novocaine. This combination of components is unique, since the action of the agent is effective against bovine teleziosis, as well as in the treatment of kerato-conjunctivitis.

IMPROVING THE ORGANIZATION OF CENTRALIZED RESTORATION OF AGRICULTURAL EQUIPMENT PARTS
Authors: Trukhanska Olena , Ostapenko Oleksii
Published: January 2024

Effective use of machines largely depends on timely and high-quality maintenance and repair. Due to the increase in the volume of restoration of units and aggregates at specialized enterprises, an opportunity was created in the workshops of farms and collective farms to more widely apply the aggregate method of restoration and repair. Improving the organization of centralized restoration of damaged parts makes it possible to restore tens of millions hryvnas worth of parts in a year. The organization of centralized delivery of material and technical means to farms is applied using the services of equipping farms with the necessary equipment in assembled, adjusted and run-in form.
Increasing the level of concentration of repair production, deepening its specialization will allow to significantly improve the quality of repair, to bring the resource of repaired machines, tractors, combines and aggregates up to 80%.
Before repairing driven discs of clutches of tractors, cars, combines, to replace friction linings, it is necessary to carry out operations of drilling, riveting and knocking off old linings. These operations require a lot of labor and the use of additional tools, which leads to significant capital investments.
The paper proposes a device for cutting the fastenings of the friction linings of the driven clutch discs. Taking into account the conditions of agricultural enterprises, which have repair workshops, and the presence of vertical boring and milling machines, it is proposed to organize their use for the operation of removing worn friction linings.
For riveting of friction linings of driven clutch discs, the development of a hydraulic stand is proposed, which can be made from standard units in the workshops of agricultural enterprises. Using this stand will make it possible to increase labor productivity when performing this operation and reduce its time.
DEVELOPMENT OF MACHINE UNIT FOR RESOURCE-SAVING TECHNOLOGIES OF SOIL PROCESSING
Authors: Shvets Ludmila , Ostapenko Valerii
Published: January 2024

Water and wind erosion are possible on crop rotation fields. By using various agrotechnical techniques, it is possible to minimize soil erosion. One of these techniques is the creation of shafts about 10 m wide and 80-100 cm high at a certain distance. Effective agrotechnical anti-erosion techniques are slitting, special porous and comb plowing, organization of soil-protective crop rotations, strip placement of winter and spring crops, grain and row crops, creation of buffer strips of grasses, liming of washed lands and drains.
In the steppes or areas where the topography of arable land has a slope, it is recommended to use various technologies of minimal tillage to counteract wind and water erosion. Surface treatment of the land ensures the accumulation of plant residues in the surface layer of the soil. This increases the amount of organic matter in the upper layers, which, in turn, improves the strength of the aggregates and the resistance of the soil to the action of raindrops and wind gusts. When plowing sloping fields, contour plowing is a useful method of reducing the risk of erosion. It uses the topography of the field to absorb water, preventing it from running down the rows.
Crop residue remaining on the surface is also a factor in which minimal tillage protects the land from erosion. In general, both plants and their remains on the surface effectively slow down the speed of movement of both water on the surface of the soil and air above it. From a physical point of view, plant cover growing on the surface, as well as plant residues, effectively protects the ground, for example, from the impact of raindrops.
If we talk about traditional crops, it should be noted that perennial grasses provide the best protection, and cereals can moderately resist erosion. When growing row crops, such as sugar beet or corn, most of the land remains uncovered, meaning that these crops provide less protection. The worst option from the point of view of erosion is steam without growing any crops and without preserving the harvest residues on the surface.
Analysis of existing machines for soil protection against wind and water erosion was carried out. The proposed design of the machine for plowless tillage.
MODELING OF WORKING BODIES FOR THE EXTRACTION OF SUGAR BEET ROOTS TAKING INTO ACCOUNT THE DYNAMICS OF SOIL STICKING ON THEIR SURFACE
Authors: Zayets Maksym
Published: January 2024

This article is devoted to the study of the process of the formation of soil adhesion on the surface of the root crop during digging, which allows in the process of modeling and designing the surfaces of the active working organs of root harvesting machines. Analyzing scientific research on this topic, it is possible to observe little attention paid to this problem, therefore the work on this topic is quite relevant. The purpose of this work is to simulate the process of soil taring, which can lead to root crop damage and a decrease in product quality.
The article provides a dynamic analysis of this process, taking into account various factors, such as moisture, stickiness and other physical and mechanical properties of the soil, digging speed, shape and geometric parameters of the root crop.
The Mohr-Coulomb method was chosen as the model, which made it possible to solve certain problems of the root crop extraction process and perform simulation of soil behavior for a wide range of load systems based on parameters, agricultural soils.
Determination of the main characteristics of the soil in the simulation of beet extraction was carried out for a moderately heavy loam in a wet state, for which most of the input parameters for the PLAXIS software were known. These samples were subjected to standard rapid triaxial tests at an initial stress of 3 kPa, up to σ3 200 kPa. possible methods of avoiding excessive soil sticking and increasing the efficiency of harvesting root crops are substantiated. The results of the research can be useful for agricultural enterprises and sugar beet producers to optimize the process, which will allow to improve the quality of the products.
Summing up, modeling the root crop extraction process is an important tool for optimizing the parameters of the harvesting machine and reducing the energy component of the digging process. This can improve the efficiency and quality of root crop production, which is important for agricultural enterprises and root crop producers. Additional research and development in this field can contribute to the continuous improvement of the root crop extraction process, which will make it possible to take into account the obtained data when designing the working bodies of beet harvesting machines.

Published: January 2024

The issue of transportation of agricultural products from the producer to the buyer is important for our country. Russia's full-scale war against Ukraine emphasized the extreme importance of the transport complex for the economy and society. With the beginning of invasion of Ukrainian land, air communication with the world was completely stopped, and sea ports were also blocked. With the beginning of hostilities on the territory of Ukraine, the routes of transportation of agricultural products were disrupted, a large number of elevators were destroyed, the road surface of warehouses was destroyed, and sea ports were seized.
The purpose of this article was to study the current state of freight transportation in the conditions of martial law, to improve and stabilize the ways of transporting agricultural products. The task was to find ways to improve logistics and ways to protect grain products from missile strikes, as well as possible ways to export this grain from the territory of Ukraine.
The article presents the results of an analytical analysis of the state of transportation of agricultural products, suggests ways to stabilize and solve the problem. The development of logistics and cooperation with foreign partners, the construction of protected hubs for storing grain products, as well as the construction of modern elevators that could accumulate large volumes of products for their further transportation in large batches to consumers. The best option for Ukraine would be the creation of grain hubs in European countries, as well as transport grain by motor vehicle, accumulate grain in large batches, and deliver it to other parts of the world, through the ports of Europe. However, today it is not so easy, because currently European countries are imposing restrictions on the import of our grain products.
Today, despite the difficult military situation, the lost part of the transport infrastructure and logistics, Ukraine is one of the largest grain exporting countries. The restoration of traditional ways of freight transportation and the constant search for new ones is a sign of a healthy and promising policy for the development of the transport industry. The European choice of our state, the support of partners will ensure uninterrupted freight transportation and will give new impetus to the development of river and railway transport.

Published: January 2024

The efficiency of planting seeds and, therefore, the yield of agricultural crops depend significantly on the characteristics of the mechanisms of copying sowing sections. These mechanisms can be conditionally divided into two categories: radial and parallelogram. Radial mechanisms with leashes are used in traditional technologies and require high-quality preliminary processing, and radial mechanisms with pressure rods are suitable for any agrophones
The durability of the movable joints of the parallelogram copying mechanism of the sowing complex depends on their resistance to wear. This stability is determined by the mode of operation, chemical composition and structure of the surface layer of parts, as well as physical-mechanical and tribotechnical characteristics.
With an average seasonal task for Agro-Soyuz Turbosem II 19-60 sowing complexes within 3–4 thousand hectares, the total service life of experimental parts is at least 4 years, which is at least four times more than in the case of serial parts.
The positive effect of the absence (or the presence within the measurement error) of wear of steel parts of movable joints that work in connection with polymer composite material (PCM) was revealed. The average resource of experimental parts in the hinges of the parallelogram copying mechanism for Agro-Soyuz Turbosem II 19-60 seeding complexes is 20589 ha. The average value of the wear of the experimental parts was determined to be 1.78 mm, and the intensity of their wear was 1.02×10-4 mm/ha. It was established that the wear of UPA-6-30 PCM parts in the moving joints of the copying mechanism occurs according to the normal distribution law ( = 0.108), which allows very accurate prediction of their resource. The consistency of the experimental distribution with the theoretical distribution was checked using the Kolmogorov criterion. It is confirmed that the distribution takes place according to the normal law. An analysis of reliability indicators during shortened tests was also carried out and the probability of failure-free operation of experimental parts made of polymer-composite material was determined. According to the results of field tests of the elements of the movable joints of the mechanism of copying the sowing complex, it was established that the resource value of 20,558 hectares exceeds the indicators of serial parts by 4 times.

Published: January 2024

Arachidonic acid (ARA) is an essential fatty acid with numerous biological activities that benefits human health. However, ARA-rich phosphatidylcholine (PtdCho), which has a higher bioavailability than ARA-rich triacylglycerols, is scarce in the natural source. In this study, we developed an enzymatic modification approach for the synthesis of ARA-rich PtdCho from ARA-rich ethyl esters (EE). The maximum incorporation of ARA into PtdCho (24.02%) was achieved from the optimized conditions, including ARA-rich EE/PtdCho mass ratio of 2:1, hexane, lipase Novozym 435 as a biocatalyst (15% of enzyme load) and reaction time of 24 h. The 31P nuclear magnetic resonance (NMR) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) results revealed that the PtdCho content decreased to 17.53% and the ARA-containing PtdCho species was primarily identified as PtdCho (18:2/20:4). Taken together, this investigation offers a new reference for the efficient production of ARA-rich PtdCho via enzymatic modification and paves a theoretical groundwork of industrial production practice.
Pharmacotherapeutic potential of Vitis vinifera (grape) in age-related neurological diseases
Authors:   Shahid Beheshti University of Medical Science, Jadidian Faezeh
Published: January 2024

Age-related neurological disorders (ANDs), including neurodegenerative diseases, are complex illnesses with an increasing risk with advancing years. The central nervous system's neuropathological conditions, including oxidative stress, neuroinflammation, and protein misfolding, are what define ANDs. Due to the rise in age-dependent prevalence, efforts have been made to combat ANDs. Vitis vinifera has a long history of usage to treat a variety of illness symptoms. Because multiple ligand sites may be targeted, Vitis vinifera components can be employed to treat ANDs. This is demonstrated by the link between the structure and action of these compounds. This review demonstrates that Vitis vinifera and its constituents, including flavonoids, phenolic compounds, stilbenoids and aromatic acids, are effective at reducing the neurological symptoms and pathological conditions of ANDs. This is done by acting as an antioxidant and anti-inflammatory. The active Vitis vinifera ingredients have therapeutic effects on ANDs, as this review explains.
المرأة والمشاركة السياسية

Published: January 2024

تنقسم هذه الدراسة إلى ثلاث أقسام، يبحث القسم الأول منها في مفهوم المشاركة السياسية، ويتناول القسم الثاني الدور السياسي للمرأة العربية في المراحل المختلفة من تطور المجتمع العربي. أما القسم الثالث فهو دراسة ميدانية حول المشاركة السياسية للمرأة العربية الليبية. 

حاولنا في القسم الأول تحديد مفهوم المشاركة السياسية انطلاقا من تحليل العلاقة القائمة بين البناء الاجتماعي والواقع التاريخي من جهة، وسلوك الإنسان السياسي من جهة اخرى، ولما كان البناء الاجتماعي بمؤسساته ونظمه المختلفة هو الذي يحدد السلوك الإنساني، فان المشاركة السياسية للمرأة العربية إنما تتوقف على مدى مشاركتها في المؤسسات الاجتماعية والإنتاجية والثقافية، وكذلك على امكانياتها الموضوعية والفعلية في تحديد وتوجيه سياسة المجتمع، فالسلوك السياسي إنما يخضع للمؤسسات الاجتماعية والبنية المجتمع. 

أما في القسم الثاني من هذه الدراسة فقد وقفنا على الأدوار السياسية والاجتماعية التي تقلبت فيها المرأة العربية في التاريخ. ولئن كانت المرأة العربية قد تحررت في صدر الإسلام مما يعوق سلوكها الاجتماعي، فدخلت ميادين الحياة مجاهدة وطبيبة ومربية.. إلخ، فان نظام الحكم العثماني جردها من هذه المكتسبات الإنسانية، وحرمها من حقوقها الطبيعية فأصبحت أسيرة البيت، واقتصر دورها على الجانب الفيزيولوجي، وبذلك عزلت المرأة عن المجتمع وصار الرجل قيمة عليها.

الشأن في دراسة مصدر أي كتاب أن تسبق بدراسة محتواه غير أن القرآن الكريم يختلف عن غيره ، فإن دراسة مصدره تختم مخالفة هذه القاعدة، ذلك أن فكرة مصدره الإلهي هي الجزء الأساسي في دعوته، إذ نراه من أول القرآن إلى آخره يتحدث إلى الرسول أو عنه ولا يتركه يعبر عن فكره الشخصي في كل جزء منه يتكلم الله تبارك وتعالى ليصدر أمرا أو ليشرع قانونا، ليخبر أو لينذر، يا أيها النبي، يا أيها الرسول، إنا أوحينا إليك، إنا أرسلناك، بلغ ما أنزل إليك ، إتل عليهم ، قل، سيقولون، افعل، لا تفعل.
ليبيا بين الجغرافيا الطبيعية والجغرافيا البشرية
Authors: الكيخيا أ.د. منصور
Published: January 2024

لكل من الجغرافيا الطبيعية والجغرافيا البشرية تأثيرها في المكان والسكان، فظواهر البيئة الطبيعية من موقع وتضاريس ومناخ وموارد بشرية تشكل الإطار الجغرافي العام للدولة ، وتتفاعل مع المكونات البشرية التي تعيش عليها، ومع التغيرات التاريخية التي مرت بها ، لتعطي الدولة معالمها، وتحدد صفاتها ، ومدى فاعليتها في محيطها الإقليمي والدولي ... أي تحدد ملامح شخصيتها .. وهذا ما تحاول هذه الدراسة تلخيصه وإبرازه في ليبيا.
ظاهرة طبيعية أثرت وما زالت تؤثر في ليبيا منذ فجر التاريخ حتى عصر النفط ، وهي كونها مساحة جغرافية واسعة من الأراضي الجافة قليلة أو نادرة الأمطار ، خالية من الأنهار والمجاري المائية .. قليلة الإنتاج الزراعي والصناعي ، منخفضة الكثافة السكانية لدرجة أن مساحات واسعة من أراضيها تكاد تخلو من السكان . هذه البيئة . فقيرة الإمكانيات والسكان - تقع جغرافياً بين جزيرتين سكانيتين عامرتين بالإمكانيات الاقتصادية والبشرية .
الموقع الجغرافي لليبيا بين هاتين الكتلتين جعلها حدا فاصلا بينهما ، ففي غربها تقع منطقة شمال أفريقية الأطلسية بمرتفعاتها وغاباتها وأنهارها ووديانها وتجمعاتها السكانية ،وفي شرقها تقع كتلة أخرى أكثر حيوية واستقراراً وسكاناً تعمر وادي النيل شماله وجنوبه منذ أزمنة موغلة في القدم. كهذا تظهر المساحة التي تشغلها ليبيا فراغا (Non écoméne) بين منطقتين عامرتین (Ecoméne) ، فهي إذن تشكل حدا فاصلا بينهما ، ومجالاً حيوياً لكل منهما .. هكذا كانت الرقعة الجغرافية التي تشكلها ليبيا على مر العصور ، تتأثر بتغيرات أوضاعها الخاصة ، وبتغيرات الكتلتين المتاخمتين لها شرقاً وغرباً ، فإذا قويت شوكة إحداهما وملكت القوة والتفوق أغراها ذلك بالتوسع ؛ فتحاول الهيمنة على الأجزاء التي تليها من ذلك الفراغ الجغرافي تأمينية للحدود وبسطة للنفوذ ، وقد يتعدى الأمر إلى أن تعبر إحداهما ذلك الفراغ محاولة السيطرة على الأخرى ، لتتحول ليبيا في هذه الحالة إلى جسر عبور للقوات المتصارعة.
Pandemia y religión: ¿más secularización o más religiosidad? Las contradicciones de la presencia religiosa en la España post-COVID 19
Authors: Ruiz Andrés Rafeel
Published: January 2024

Cuando irrumpió la pandemia de la COVID-19, se expandió social y mediáticamente la sensación de que nada volvería a ser igual. Pasados unos años, hemos comprobado cómo la pandemia no ha implicado un cambio profundo de las tendencias que estábamos experimentando anteriormente, sino que ha primado la voluntad de normalidad y de continuación de la vida. En este texto me adentraré en las trayectorias religiosas a partir de 2020, rastreando la evolución de las dos posibles alternativas que ya entonces fueron descritas: una sociedad postpandémica más secularizada o más religiosa/espiritual. Para ello, me centraré en la  contextualización de las dinámicas previas a marzo de 2020, las reflexiones surgidas en el momento de mayor preocupación colectiva por la COVID-19 y la evolución posterior, concluyendo que el impacto más importante de la pandemia en este ámbito ha sido la intensificación de las contradicciones sociorreligiosas en sociedades como España.
La sinodalidad como alternativa a una Iglesia polarizada. Análisis del documento de trabajo de la etapa continental
Authors: García Maestro Juan Pablo
Published: January 2024

Caminar hacia una Iglesia sinodal implica tomar conciencia de las tensiones que genera vivir la unidad en la diversidad. Una de las tensiones es la de quedar atrapado en el conflicto, que es lo que estamos viviendo en nuestra Iglesia tan polarizada. Cuando nos quedamos atrapados en el conflicto se estrechan los horizontes, se pierde el sentido de la totalidad y nos fragmentamos en subidentidades. Es la experiencia de Babel y no la de Pentecostés. Otra tensión es la de separarse espiritualmente, desinteresándose de las tensiones en juego, continuando la propia senda sin implicarse con los cercanos en el camino. Por el contrario, “la llamada es a vivir la tensión entre la verdad y la misericordia, como hizo Jesús. El sueño es el de una Iglesia que vive plenamente una paradoja cristológica: proclamar con audacia la propia enseñanza auténtica y, al mismo tiempo, ofrecer un testimonio de inclusión y aceptación radicales mediante un acompañamiento pastoral basado en el discernimiento” (DEC 30).
¿Por qué una asignatura de religión confesional en la escuela?
Authors: Esteban Garcés Carlos
Published: January 2024

La presencia de la religión confesional en la escuela suele ser impugnada por ser una propuesta particular en un espacio común. Aunque haya otros escenarios posibles, este artículo fundamenta algunos porqués de un enfoque confesional para el hecho religioso en la escuela, extensible al ideario católico que pueden tener los centros escolares en una sociedad plural. Una clave será que tener identidad particular es precisamente común a todos y todas, desde ahí construye lo público y la pluralidad; otra será la necesidad educativa de promover visiones de la vida con sentido para que los alumnos puedan elegir con libertad su proyecto vital. Para educar la diversidad parece necesario conocer las posibles identidades a las que, lógicamente, se les exige respetar una ética mínima  ompartida y basada en la dignidad humana. Así, la presencia de la enseñanza de religión, confesional o no, puede ser una aportación al bien común.

THE EFFECT OF WORK SYSTEMS, ORGANIZATIONAL BEHAVIOR, PSYCHOLOGICAL WELL-BEING, AND ORGANIZATIONAL COMMITMENT, ON JOB SATISFACTION
Authors: Dewi Truli Susatyo , Abadi Ferryal
Published: January 2024

State Civil Apparatus (ASN) must have high performance. High-Performance Work Systems (HPWS) can increase employee and organizational productivity. In this study, we examine how HPWS relates to Organizational Citizenship Behavior (OCB), how psychological well-being (PWB) influences job satisfaction, and examine how PWB, organizational commitment, and job satisfaction function as mediators of HPWS-OCB interaction with the ASN population in 42 DKI Jakarta Provincial Government Organizations (OPD). Sampling was taken by purposive sampling, with ASN requirements with a minimum working period of 1 year. The survey was conducted in June 2023 to obtain data from 185 respondents who received 33 questions via Whatsapp. The data were evaluated using the Structural Equation Model Partial Least Square (SEM-PLS). HPWS has a significant positive effect on PWB and organizational commitment. HPWS does not affect OCB. The positive HPWS-OCB relationship can be fully moderated by PWB. PWB has a significant positive effect on organizational commitment and will increase OCB. HPWS does not affect job satisfaction. HPWS through PWB mediation and organizational commitment has a significant effect on job satisfaction. Organizational commitment does not mediate the HPWS-OCB relationship. Job satisfaction does not affect OCB. Government organizations should implement HPWS in ASN management so that ASN feels PWB and in the end voluntarily carry out OCB, which leads to improving the quality of excellent service and organizational performance

Authors: Butarbutar Injen Pardamean , Purnamasari Novia , Safitri Koko
Published: January 2024

This research aims to conduct an analysis of Five Forces and BCG Matrix for Apple Inc. The Five Forces analysis is used to evaluate the competitiveness of the industry in which Apple operates, while the BCG Matrix is employed to measure the company's product portfolio. Data for this study are sourced from reliable resources, including the company's financial reports, industry reports, and related publications. The Five Forces analysis reveals that the technology and software industry in which Apple operates is highly competitive. Threats from major competitors, the level of product substitution, and the bargaining power of buyers significantly impact the company's strategies and performance. However, Apple's strong brand equity and robust product ecosystem provide a competitive advantage in navigating the pressures from these five forces. In the BCG Matrix analysis, Apple's core products such as the iPhone, iPad, and Mac show a position of stars and question marks, indicating high growth potential. On the other hand, some older products and unproven innovations fall into the category of cash cows and dogs, with lower growth prospects. The results of the Five Forces and BCG Matrix analysis provide a comprehensive overview of Apple's market position and aid in formulating the company's long-term strategies. Apple's management can leverage these findings to optimize the product portfolio and address competitive challenges in the ever-evolving technology industry. While Apple holds a strong market position, new challenges will continually emerge, necessitating effective strategies to maintain competitiveness and ensure the company's growth in the future.
