Authors: Tsisinska Oksana , Podolchak Nazar
Published: February 2023

The article defines “public administration” as a set of principles, methods, forms, and means of impact on the activity of a region and a country as a whole. The operation of the mechanisms of interaction between public administration entities in cross-border cooperation is recommended to be categorized by interaction entities in the public domain, which, in turn, are divided by the number of entities, their composition, role, and participation. The article provides the classification of the mechanisms of interaction between public administration entities in the framework of cross-border cooperation: by the coverage with a legal framework that secures interaction, by the coverage with interaction, by the types of cooperation between interaction entities in a border region where a regional authority is the main entity, by the types of cooperation between interaction entities in cross-border region or space where a regional authority is the main entity, by interaction scope, by the results of interaction, by interaction intensity, by the levels of formalization and public administration, by initiative, by cooperation effect in a border region, and by the duration of cooperation. The mechanisms of interaction between public administration entities in a cross-border region or space are suggested to be divided by the features of interaction, coverage (based on the boundaries of cross-border space), activity sectors, the impact of other entities and institutions operating beyond the public domain, etc. The instruments of cross-border cooperation most frequently used by public administration entities at border areas of Ukraine are outlined, including international agreements, border cooperation agreements, Local Border Movement Agreements, Neighborhood Programs, joint cross-border development strategies, regional development strategies with priorities set on cross-border cooperation, regional cross-border cooperation development programs, new cross-border cooperation forms (Euroregions, clusters, industrial zones and parks, etc.), direct contacts – meetings, events, forums, etc. The article specifies the principles of public administration, including structural principles, principles of process, and principles of the final result.
SOURCES OF TRAUMATIC EXPERIENCE & CROSS-CONTOUR MENTAL HEALTH RECOVERY TECHNOLOGY
Authors: Kalishchuk Svitlana , Korvat Larysa
Published: February 2023

The article highlights the sources of psycho-emotional patterns of traumatic experience and outlines a cross-contour technology for overcoming their prolonged impact on human mental health. The mechanisms of semantic coding and decoding of events in the world by a person are defined. Three hierarchical contours of human consciousness are objectified, each of which contains both principles of mental health protection and risks of its violation. Using methods of bodynamic, transpersonal and projective approaches it is proved that the person's reaction to traumatic events is determined by his pre-biographical and early biographical experience. The presented cross-contour technology allows to increase resilience to crisis events of war, to reduce uncertainty and to activate personal dimensions of freedom and responsibility. The corrective component of the technology focuses on the reorganization of the person's semantic system in response to the crisis events of the world. The purpose of the technology is to reduce uncertainty and hesitation and activate the dimensions of freedom and responsibility. The subjective specificity of the world creation by a human is revealed, that is, reflection, generation and understanding of reality
Growth Hormone and Growth Retardation in Autoimmune Type-1 Diabetes. Insulin an Important Endocrine Growth Factor
Authors: Aziz Kamran Mahmood Ahmed
Published: February 2023

Growth hormone (GH) secretory alterations and dysregulations with insulin-like growth factor-I (IGF-1) axis among type-1 diabetic children and adolescents is well established. In this poorly controlled abnormal metabolic state, GH hypersecretion is observed with decreased levels of Insulin-like Growth Factors (IGFs), IGF binding proteins-3 (IGFBP-3), and growth hormone binding protein (GHBP). These all factors results in decreased growth velocity and growth retardation in type-1 diabetic children and adolescents. Insulin is the most important metabolic regulator of this system. Absolute insulin deficiency, as observed in type-1 diabetics, is the primary cause of this dysregulation and alterations. Several published studies have shown that elevated HbA1c and poor glycaemic control are the main factors of this abnormal metabolic state. Conversely, studies have also demonstrated that good glycaemic control with basal bolus insulin regimens or insulin pump can improve diabetic state with restoration of normal growth. Hence this perspective review focuses on these important aspects of growth abnormalities in type-1 diabetic patients and concludes that health care policy makers should develop a close monitoring program and system with multi-disciplinary team approach to prevent further diabetes related growth complications.

Authors: JJ De Agustin
Published: February 2023

Objective: To assess the sensitivity and specificity of the “horse saddle” sign in the diagnosis of osteoarthritis Methods: An exploratory clinical comparative cross-sectional study where an ultrasound of the hands and comparative radiographs in PA view were performed on patients with osteoarthritis, inflammatory arthritis and healthy patients seen in the Rheumatology clinic of the Vall de Hebron Hospital. Age, sex and time of evolution of the disease were collected as clinical variables. The MCP, PIP and DIP joints from the second to the fifth finger of both hands were viewed with grayscale in longitudinal and transverse plane of both the dorsal and palmar face, assessing for osteophytes, synovitis and the horse saddle sign. Results: A total of 38 patients with osteoarthritis, 20 patients with inflammatory arthritis (8 psoriatic, 9 RA, 1 LES, 1 PMR and 1 Sjogren) and 2 healthy patients were assessed. It was found that the horse saddle sign had a sensitivity of 66.7% and specificity of 86.4% in osteoarthritis showing a p-value of 0.052 by means of the chi-square test. 87% of patients with the horse saddle sign had osteoarthritis and only in 2 patients with RA and in the patient with LES. Conclusion: The horse saddle sign is an ultrasound sign with good sensitivity and specificity for the diagnosis of hand osteoarthritis comparable to other classic ultrasound signs such as osteophytes and synovitis.

Authors: R Divisha
Published: February 2023

Traditionally, the practice of using herbal medicines for diseases of livestock and poultry has given numerous benefits to the farmers. Since poultry are reared intensively, a high incidence of diseases poses a big threat to small - scale poultry production systems. The major poultry diseases prevalent among chicken include Avian influenza, Marek's disease, Coccidiosis, Fowl typhoid, Ranikhet disease and Chronic respiratory disease . In order to control the disease occurrence and prevent huge mortality, farmers are opening up to alternatives such as ethno veterinary medicine as they provide a substitute to newer expensive poultry drugs.
The Dignity of Democracy in the Appointment of Acting Regional Heads by the President: Legal Construction After the Constitutional Court Decision Number 15/PUU-XX/2022
Authors: Riadhussyah M , Farhan Farhan , Hamdani Fathul , Nata Kusuma Lalu Aria
Published: February 2023

Purpose of the study: The purpose of this study is to examine the legality of the position and authority of the acting regional head, as well as to examine the dignity of democracy in the appointment of acting regional heads by the president and its construction after the Constitutional Court Decision Number 15/PUU-XX/2022.
Methodology: This study applies normative legal research methods using a statutory, conceptual, and case approach.
Results: The results of the study show that the appointment of acting regional heads is the operationalization of the concept of politically appointed presidential power and not the concept of election (political elected) as regional heads.  The consequence is a lack of regional legitimacy and a lack of relations with the people because it is not the people's choice.  This condition shows a portrait of the decline of democracy in the regions.  In this case, the government should prepare by making implementing regulations related to the mechanism for selecting regional heads by not degrading the democratic values as mandated by the Constitutional Court in its decision Number 15/PUU-XX/2022.
Applications of this study: This article provides an analysis of how democratic principles should still be applied in the process of appointing acting regional heads.  This research is expected to be useful and can be a reference material for those who conduct research, especially with regard to the appointment of the acting regional head.  Thus, this research is expected to enrich the scientific treasures and studies related to the mechanism for appointing acting regional heads.
Novelty/ Originally of this study: The research related to the appointment of acting regional heads is still very minimal.  So with the research that examines the dignity or portrait of democracy in the mechanism for appointing the acting regional head, it is considered very important as reference material in the process of implementing democracy in Indonesia.

Published: February 2023

The aim of the work was to study the features of the rabies epizootic process manifestation in the territory of the Rostov region. To achieve the intended aim the comprehensive epizootological research and the retrospective epizootological analysis were carried out based on the veterinary reports of the Rostov Region State Budgetary Institution «Rostov Regional Station for Animal Diseases Combating, with Anti-Epizootic Squad» and the Rostov Region Veterinary Medicine Directorate. In the result of research it was found that for the period from 2018 to 2021, 35 rabies epizootic foci were registered within the territory of 24 municipalities of the Rostov region. During this period of time the disease was detected in 8 species of domestic and wild animals. The main reservoir and source of rabies infection causative agent in this territorial entity of the Russian Federation are dogs (31.4 %), foxes (22.8 %), cats (14.3 %), cattle (14.3 %) and jackals (8.5 %); single cases of the disease (8.7 % in total) were detected among wolves, martens and horses. When analysing the annual dynamics of the rabies incidence in animals, the clear-cut seasonality of the disease is discovered. The disease is mainly recorded in the autumn-spring period, whereby the seasonal dynamics has the two-peak character with two highest points in April and November. Such seasonal fluctuations are explained by the breeding biology of wild carnivores, such as foxes and jackals, with wolves and martens involved in the epizootic process. The unstable and tense rabies epizootic situation in the Rostov region indicates the need to regulate the number of wild carnivores on its territory and to carry out planned activities on their immunization.

Published: February 2023

Aim: Our aim was to compare the direct enzymatic measurement with four formulas which are used in determining the value of low density lipoprotein cholesterol (LDL-C) levels.

Material and methods: A total of 33842 patients’ files were retrospectively reviewed and data was collected. Triglyceride (TG) group 1, 2, 3, 4 and 5 were consisted of TG levels ≤99 mg/dl, 100-199 mg/dl, 200-299 mg/dl, 300-399 mg/dl and ≥ 400 mg/dl, respectively. LDL-Group 1, 2, 3, 4 and 5 were composed of LDL-C≤100 mg/dl, 101-130 mg/dl, 131-160 mg/dl, 160-190 mg/dl and >190 mg/dl, respectively.

Results: All formulas tended to undervalue LDL-C concentrations compared to direct method (p<0.001 for all). The Chen formula had higher degree of correlation compared to other formulas. Acceptable result of Friedewald formula was 53.77%, Chen formula was 62.72%, Hattori formula was 24.72, and Anandaraja formula was 45.98%. Bland-Altman plot results showed disagreement of four formulas with significant proportional and systematic bias compared to direct method. There was no agreement of calculated LDL-C with direct LDL-C when the data was subgrouped according to TG levels. No agreement between direct LDL-C and calculated LDL-C was found. Correlation analysis showed moderate to high level of correlation for Friedewald, Chen, and Hattori calculations, whereas Anandaraja formula showed low to moderate correlation. The Friedewald and Anandaraja formulas mostly misclassified LDL-Group 3 subjects, whereas the Chen and Hattori formulas mostly misclassified LDL-Group 4 subjects.

Conclusion: The Chen formula might be an acceptable alternative of the Friedewald formula and other formulas.

Published: February 2023

Introduction: The study of the genetic aspects of bone metabolism disorders in children is a theoretical and practical interest for pediatrics, especially according to the age and ethnic positions. There is a number of gene polymorphisms (primarily the vitamin D receptor (VDR) gene) that determine the norm and pathology of bone tissue formation. Calcium absorption worsens when there is no functional VDR and active forms of vitamin D. As a result the level of bone mineralization decreases. In children such disorders lead to the development of osteopenia.

Objective: To determine the frequency of allelic variants of the VDR gene (rs1544410, rs2228570) and to evaluate its relationship with the level of vitamin D in children under one year old in the Kazakh population.

Material and methods: 197 children under one year of age were examined for vitamin D by electrochemiluminescent immunoassay and genotyping of the VDR polymorphism (rs1544410, rs2228570) by PCR.

Results: It was found out that children with the C allele of the VDR rs2228570 gene have a reduced level of vitamin D by 1.84 times (95% CI 1.10 - 3.07) and CC - by 2.3 times compared with children with normal vitamin D levels.

Statistical analysis by the Kruskal-Wallis method showed that the serum level of vitamin D in AA carriers for the VDR rs1544410 was significantly reduced comparing to the level in GG and GA carriers (p=0.03).

Conclusion: The study confirms the need for further in-depth study of the genetic aspects of bone metabolism disorders in children for the development of personalized medicine.

Authors: Guliev Namig Nizami
Published: February 2023

The article highlights the results of studying the follow target mode on board the ships equipped with dynamic positioning (DP) systems. There is analyzed the position of a ship in a follow target mode when the DP mode is on, as well as the ability of a ship following a target to hold the position and course under given environmental conditions. Ships equipped with the DP system have strict requirements regarding the parameters of the follow target mode. There are listed the advantages for specific operations: technical servicing the oil and gas fields, examining the pipelines, hydrographic surveys, etc. Functionality of the hydroacoustic reference system, which is the main component of the ship follow target system, is studied. It has been stated that the follow target mode allows the ship to follow the target automatically. In most cases, the target is an unmanned remotely operated vehicle (ROV). ROV is a robot performing specific tasks under water controlled from the ship. ROV support vessels specialize on such operations. The ROV equipment and capabilities depend on the complexity of the task. The simplest tasks are inspection of the pipeline, platform supports, watching divers, visual inspection of an object lowered to the bottom, etc., when ROV is equipped with cameras, searchlights and, occasionally, sonars. To carry out the construction work or maintain the underwater facilities there are needed the servicing ROVs equipped with tools for specific purposes. There has been illustrated a model chart of the ship motion and dislocation of the ROV working area. Connection between ROV and the ship by means of a fiber optic cable is considered in detail, the advantages and disadvantages of this connection are listed. Conclusions are drawn about the widespread use of DP systems on modern ships, in particular those operating in the oil and gas industry, as well as in other areas of marine operations.

Authors: Golovko Sergey Vladimirovich , Kulakhmetov Rustam Faridovich , Kaliev Renat Garifullaevich , Nenastyev Egor Aleksandrovich
Published: February 2023

The article considers the methods of upgrading the system of cable supply from the vessel. The system controls operation of the electric motor, through which the cable is unwound from the reel, and regulates the position of the guide which delivers the cable into the water. The need to create an automatic system for laying cable from a ship, which will provide the minimal deformation and minimal cable consumption, is proved. The first system is designed to control the speed of the electric motor that unwinds the cable from the reel. Adjustment is carried out due to the signal from the tension sensor (current signal is 4 - 20 mA). The signal goes to the programmable logic controller. The analog output signal from the controller (the current signal also ranges within 4 - 20 mA) is fed to the frequency converter, which, in turn, changes the rotation speed of the electric motor in accordance with the prescribed program. The second system is designed to change the position of the guide delivering the cable overboard. The proposed system compensates for the change in the position of the cable in the water under the influence of the current. The adjustment is made depending on the signal from the angle change sensor, which will go to the programmable logic controller. The first system is considered in detail, its electrical circuit diagram and electrical functional diagram are presented, as well as other elements of the system (sensor, programmable logic controller). A description of the circuit operation is given
Kinetics of motor oil aging in marine diesel engines under continuous and periodic refill to compensate loss
Authors: Tarasov Maxim Igorevich , Kicha Gennadiy Petrovich
Published: February 2023

The article considers the balance of the engine oil aging components in the diesel engine lubrication system with the refinement of oil composition caused by the oil product loss. The motor oil aging process has been identified under continuous and periodic oil refill in order to replenish the lubrication system with fresh oil which would compensate the burnt off oil products. There were derived and solved the differential equations of the oil product balance for such aspects of aging as contamination by insoluble impurities and multifunctional additives impact, which helped understand the general regularities and kinetics of the studied process. Novelty of the approach to theoretical description of the process consisted in the fact of filtering the insoluble and colloidal components of mechanical impurities and additives by the purification and burnout means. Cyclic picture of aging allows to analyze the state of the oil aging before and after refill with its periodic refreshment. The dependence is transformed and presented in a form where it is possible to determine the state of the oil at each aging cycle, without examining the intermediate concentrations of impurities and additives. The advantage of the obtained kinetic integral expressions for oil aging is the ability to determine the conditions for a long-term or permanent mode of its use in the lubrication system of a diesel engine. There are given the formulas by which the intensity of filtration and the concentration of additives in fresh oil or the time of their impact are calculated at a given oil loss and provide a pre-rejection mode of using circulating luboil in a diesel engine.

Published: February 2023

Extraction of alluvial sand and gravel materials is a large industry. It has been widely developed in many regions of Russia, which has an increasing impact on the riverbed processes in the form of changes in the morphological structure of riverbeds and floodplains under the influence of changing flow hydraulics. Changes in the hydrological regime and morphology of the riverbed can bring negative effects and progress over time, as well as at a considerable distance from the mining sites, as can be seen from the examples, which indicates the need for their comprehensive study. Leading higher educational institutions and research organizations in the field of hydrology, water transport and fisheries study the problems of the impact of anthropogenic changes in river beds. Summarizing the experience, it is recommended to predict the impact of a potential quarry on the hydrological conditions and morphology of the whole river section by numerical modeling of the channels in 3-D problem formulation. Different technological schemes of open pit mining are considered and modeled, the most acceptable (sparing) option minimizing the negative impact on the environment is selected and justified. In order to control the results obtained by numerical simulation, studies were also carried out using the methods recommended by the regulatory literature. Analysis of the results revealed their great convergence. The final results of the research were compared with the allowable parameters in the regulatory documents, recommendations were made on improving the quarry mining technology for minimizing its negative impact on the channel processes and the resulting transport logistics.

Methods: It is a descriptive qualitative study. Conclusion: By using Dozier and Broom’s theory regarding the role of PR, this study proved that PR successfully helps overcome internal communication barriers experienced by nurses and patients. It plays as an expert advisor by providing input to hospital management and bridging the communication between nurses and patients. PR also acts as a problem solver by providing training on communicating correctly. Implications: Communication barriers can be overcome if nurses have good communication skills and understanding. As a support for the hospital system, PR provides regular communication training for nurses struggling to serve patients during the covid-19 pandemic.

Tres movimientos para la transformación curricular: la extensión universitaria como engranaje
Authors: Pérez de Maza Teresita
Published: February 2023

Mediante el abordaje de los conceptos de flexibilidad, apertura e integralidad, en el presente artículo se exploran tres movimientos instituyentes en la universidad latinoamericana que ejercen tensión en el determinismo curricular y que ubican a la extensión universitaria como «motor del engranaje» para la transformación curricular: la integralidad, la curricularización y la territorialización. Se concluye que la extensión universitaria necesita recuperar su rica tradición latinoamericana en torno al compromiso de la universidad con los sectores excluidos y con la transformación de la sociedad, lo que la aproxima como función práxica, sociopolítica y síntesis de toda la universidad.

En el presente artículo se hace un análisis de los aspectos más relevantes de la matriz energética de Colombia y una indagaciónde las estrategias de producción, desarrollo y adaptación de las energías renovables en el país y su impacto en cuanto a la disminución de emisiones de Gases Efecto Invernadero (GEI). El desarrollo de este documento parte del Plan Nacional Colombia, Diario energético 2050, elaborado por La Unidad de Planeación Minero-Energética UPME. En él se establecen las metas propuestas frente al marco energético del país. Así mismo, en este artículo se hace una revisión de los aspectos generales de energías alternativas como eólica, solar, geotérmica, hidráulica y biomasa, que permite establecer el potencialde Colombia en este tipo de energías. La investigación realizada permitió concluir que existen leyes e incentivos, principalmente de carácter tributario, que promueven el desarrollo de las energías renovables. Sin embargo, son necesarios mayores esfuerzos por parte de las entidades gubernamentales para establecer políticas que permitan desarrollar un mercado potencial para este tipo de energías y que cumplan con los requerimientos de sostenibilidad ambiental, social y económica para el desarrollo energético del país

“La ciudad informal: la loma de San Lázaro en Tunja” es el resultado del trabajo conjunto entre la Universitá Degli Studi Roma y la Universidad de Boyacá a lo largo de los talleres realizados entre los años 2015 y 2017 y del II Taller Internacional de Arquitectura – Ciudad informal” en el 2015, durante los cuales los docentes de las dos instituciones trabajaron una metodología de aprendizaje basado en problemas y plantearon varias alternativas de solución a la problemática del lugar, una zona que conjuga la tradición indígena, colonial y el ser un punto clave en la Ruta Libertadora con la realidad de un sector de invasión, ilegal, sin servicios públicos, equipamentos y espacio público. Estas propuestas constituyen el inicio de proyectos de investigación que aborden el tema y busquen soluciones sostenibles a los procesos de urbanización y ordenamiento territorial.

The present study aimed to assess the effects of three probiotic-supplemented diets on growth, cecal fermentation, blood biochemical, and intestinal morphological features in growing rabbits reared under summer conditions. Rabbits were allotted into four groups: G1 rabbits were fed the basal diet (control), G2 rabbits received Enterococcus faecium (EF) and Clostridium butyricum (CB) complexes (1 × 108 and 2.5 × 106 cfu/kg diet, respectively), G3 rabbits were given CB (2.5 × 106 cfu/kg diet) and yeast complexes (1 g/kg diet), and G4 rabbits received EF (2 × 108 cfu/kg diet) and yeast (1 g/kg diet). G2 rabbits exhibited the highest performances in terms of enhanced body weight and weight gain, protein efficiency ratio and feed conversion ratio (P<0.05). Serum total protein, globulin, immunoglobulin M, and highdensity lipoprotein concentrations were higher in probiotic-fed rabbits than those in controls. Additionally, lipid profile parameters were significantly reduced in the probiotic-fed rabbits, with the lowest concentrations measured in G4 rabbits (P<0.05). Rabbits given EF and CB had the highest total volatile fatty acid (VFA ) and propionic acid levels and the lowest ammonia concentrations. Increased villi length and muscular layer thickness and reduced crypt depth were observed in rabbits receiving EF and CB compared with the values obtained in controls (P<0.05). In summary, supplementing fattening rabbit diets with EF and CB, as a novel formulation, might be a promising and easy method to enhance growth performance under hot climate conditions by improving the feed utilization, immune response, serum lipid profile, cecal VFA production, and duodenal morphology.

Nile tilapia is known for its relative tolerance to some biotic and abiotic stressors. However, long-period water exchange may impair the health status and, thereby, the growth performance and feed utilization. In this regard, using herbal extracts may help to relieve the adverse impacts of low water quality on the productivity of this fish species. A 100-day feeding trial was designed to examine the effects of dietary supplements of Aloe vera leaves (AVE), and chamomile flowers, Matricaria chamomilla (CFE) extracts on water quality, growth performance, and well-being of Nile tilapia. Fish (3.95±0.05 g, n=1200) were distributed into five groups (15 fiberglass tanks, 2 m3) under a water exchange rate of 20% every two days for standard control (T0) without herbal supplements. Groups (T1, T2, T3, and T4) were exposed to a long water exchange period of 50% every month, wherein T1 (stressed control), T2, T3, and T4 groups were fed a diet supplemented with 0% herbal extract, 1% AVE, 1% CFE and 0.5% AVE +0.5% CFE, respectively. Results showed that feeding on a T2 diet exhibited a clear improvement under a long period of water exchange stress, and it is almost similar to their counterparts under normal conditions (T0) in terms of specific growth rate, survival rate, feed intake, feed conversion ratio, and protein efficiency ratio. Moreover, the lowest levels of aspartate aminotransferase were obtained with T2 and T0. In addition, the highest white blood cell count and hemoglobin values were recorded with group T0, followed by T2, and T4, while there was no significant difference between T3 and T1. Fish under stressed conditions without herbal extracts (T1) showed the lowest performance and survival rate compared to T0 and T2 groups. In conclusion, feeding diet supplied with 1% A. vera extract to stressed fish restored their performance and well-being to the level of their counterparts under normal conditions.
A Moral Entrepreneur in the Land of Consensus: Making School Policy in Switzerland
Authors: Fouquet-Chauprade Barbara , Revaz Sonia , Charmillot Samuel
Published: February 2023

This article examines the way in which political decisions on schooling are made, with the double constraint of a search for consensus, anchored in Swiss politics, and the presence of moral entrepreneurs (Becker, 1985).We analyse the tensions that this creates in the design of a reform of lower secondary education and the forms that the conflict takes. The analyses show an over-politicisation of educational issues, exacerbating the divisions between policy actors.
