THE AGREEMENT ON TRADE-RELATED ASPECTS OF INTELLECTUAL PROPERTY RIGHTS (TRIPS)

he paper delves into the development and intricacies of international legal frameworks for intellectual property (IP) rights protection and commercialization, focusing on agreements like the Paris and Berne Conventions. It outlines the evolution from initial measures safeguarding industrial property to broader copyright and trademark protections, facilitated by entities such as the World Intellectual Property Organization (WIPO) and the World Trade Organization (WTO). The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) is highlighted for establishing minimum standards for IP protection and enforcement, integrating provisions for dispute resolution, and managing the balance between IP holders' interests and the public good. TRIPS' role in addressing challenges posed by differing national norms and its efforts to mitigate IP rights abuse through limitations and exceptions, known as the Three-Step Test, are emphasized. This analysis underscores the importance of a fair and balanced IP system that promotes global innovation and creativity, acknowledging the need for a harmonious integration of varied national laws within the global trade and IP protection landscape.

Power quality improvement of unipolar-input-bipolar-output DC transmission system via load power balancing

In DC transmission and distribution systems, both unipolar and bipolar transmission modes exist, and DC transformers used in these systems are also available in either unipolar or bipolar configurations. In actual systems, due to requirements such as economy, land occupation, and reliability, there is a tendency to use a system with unipolar input and bipolar output. However, the bipolar loads, if unbalanced, will lead to increased equipment costs and voltage imbalance, causing power quality problems. This paper defines the Power Unbalance Factor (PUF) to describe the power quality of the studied DC transmission system and presents an improved DC transformer topology based on a power balancing system. This topology realizes bipolar voltage balance and improves the power quality of the DC transmission system when the load is unbalanced. The influence of the proposed solution on the power design of the DC system is demonstrated through theoretical analysis, and its effectiveness for improving the DC power quality is verified by both simulations in MATLAB/Simulink environment and physical experiments. When the power electronic transformer needs to be overloaded, the proposed topology can reduce the design power of the two branches by using the difference power, which is economical.

A semi-automatic analytical methodology for characterizing the energy consumption of MRI systems using load duration curves.

Magnetic resonance imaging (MRI) scanners are a major contributor to greenhouse gas emissions from the healthcare sector, and efforts to improve energy efficiency and reduce energy consumption rely on quantification of the characteristics of energy consumption. The purpose of this work was to develop a semi-automatic analytical methodology for the characterization of the energy consumption of MRI systems using only the load duration curve (LDC). LDCs are a fundamental tool used across various fields to analyze and understand the behavior of loads over time. An electric current transformer sensor and data logger were installed on two 3T MRI scanners from two vendors, termed M1 (outpatient scanner) and M2 (inpatient/emergency scanner). Data was collected for 1 month (7/11/2023 to 8/11/2023). Active power was calculated, assuming a balanced three-phase system, using the average current measured across all three phases, a 480V reference voltage for both machines, and vendor-provided power factors. An LDC was constructed for each system by sorting the active power values in descending order and computing the cumulative time (in units of percentage) for each data point. The first derivative of the LDC was then computed (LDC'), smoothed by convolution with a window function (sLDC'), and used to detect transitions between different system modes including (in descending power levels): scan, prepared-to-scan, idle, low-power, and off. The final, segmented LDC was used to measure time (% total time), total energy (kWh), and mean power (kW) for each system mode on both scanners. The method was validated by comparing mean power values, computed using the segmented 1-month LDC, for each nonproductive system mode (i.e., prepared-to-scan, idle, lower-power, and off) against power levels measured after a deliberate system shutdown was performed for each scanner (1 day worth of data). The validation revealed differences in mean power values<1.4% for all nonproductive modes and both scanners. In the scan system mode, the mean power values ranged from 29.8 to 37.2kW and the total energy consumed for 1 month ranged from 11106 to 14466kWh depending on the scanner. Over the course of 1 month, the portion of time the scanners were in nonproductive modes ranged from 76% to 80% across scanners and the nonproductive energy consumption ranged from 8010 to 6722kWh depending on the scanner. The M1 (outpatient) scanner consumed 99.9 and 183.9kWh/day in idle mode for weekdays and weekends, respectively, because the scanner spent 23% more time proportionally in idle mode on the weekends. A semi-automatic method for quantifying energy consumption characteristics of MRI scanners was introduced and validated. This method is relatively simple to implement as it requires only power data from the scanners and avoids the technical challenges associated with extracting and processing scanner log files. The methodology enables quantitative evaluation of the power, time, and energy characteristics of MRI scanners in scan and nonproductive system modes, providing baseline data and the capability of identifying potential opportunities for enhancing the energy efficiency of MRI scanners.

Why might cord blood be a better source of platelets for transfusion to neonates?

Thrombocytopenia (defined as a platelet count <150×109/L) is a common condition in preterm neonates and may occur in 18-35% of all infants admitted to the Neonatal Intensive Care Unit (NICU). Neonatal platelet functionality in terms of reactivity is often described as reduced compared to adults, even in healthy, term neonates. However, this platelet "hyporeactivity" does not correspond to a global functional impairment of the normal delicately balanced neonatal hemostatic system. The extent to which neonatal thrombocytopenia and platelet hyporeactivity contribute to the bleeding risk in preterm neonates remains unknown. Prophylactic platelet transfusions are often administered to them to reduce the risk of bleeding. However, recent literature indicates that adopting a higher platelet transfusion threshold than a lower one results in significantly higher death rates or major bleeding and can be harmful. Although the mechanism by which this occurs is not entirely clear, a mismatch between adult transfused platelets and the neonatal hemostatic system, as well as volume overload, are speculated to be potentially involved. Therefore, future research should consider novel transfusion products that may be more suitable for premature neonates. Blood products derived from umbilical cord blood (UCB) are promising, as they might perfectly match neonatal blood features. Here, we discuss the current knowledge about UCB-derived products, focusing on UCB-derived platelet concentrates and their potential for future clinical application. We will discuss how they may overcome the potential risks of transfusing adult-derived platelets to premature infants while maintaining efficacy.

AN ONTOLOGICAL MODEL OF WORKERS’ REMUNERATION WITHIN THE CONTEXT OF AN ENTERPRISE DIGITAL TRANSFORMATION

The article is devoted to issues related to the modeling of the business process of forming wages for manufacturing enterprise workers in the context of digital transformation. The importance of modeling the business process of paying workers is shown, on which the efficiency of the production process largely depends, and, accordingly, the efficiency of the enterprise as a whole. A model for the formation of workers’ wages has been developed, including information, technological and organizational aspects. An objective assessment of the work of workers leads to increased motivation, high-performance and high-quality work. The application of a balanced scorecard system is shown, which makes it possible to move from strategy to operational planning, taking into account the mutual influence of four modules – financial, production, consumer and innovation. Together, these modules have a significant impact on improving the efficiency of the entire enterprise. However, without digital transformation, it is impossible to consider the innovative activity of an enterprise. In addition, it is only in the conditions of digital information that it is possible to abandon the poorly documented distribution of shift-daily tasks to workers and promptly monitor their implementation. The development of a methodology for paying workers leads to the fact that having operational results of production activities, it is possible to objectively evaluate the work of workers, monitor their activities and determine the amount of encouragement not only once a month, but also daily. The implementation of this technique allows you to activate workers to perform shift-daily tasks within the time limits set by the plan and in the prescribed range, increase production discipline, encourage economical use of material, energy and other resources. In addition, production information is promptly displayed in the management system, which allows managers to have an up-to-date picture of the production plan implementation.

Factors influencing millennial employees’ turnover intention in multinational corporations in Penang, Malaysia

This quantitative study explores the influence of organizational culture on the turnover intentions of millennial employees within multinational corporations (MNCs) in Penang, Malaysia. As millennials increasingly comprise a substantial portion of the workforce, their turnover rates have significant implications for organizational efficacy. The research examined the relationship between key elements of organizational culture—namely employee empowerment, work-life balance, and reward systems—and millennials’ decisions to stay with or leave their employers. Data were gathered through a questionnaire distributed to 183 millennial employees in the Penang MNC sector, employing a random sampling approach and utilizing Google Forms for submission. The survey instruments were based on established scales from prior research to ensure robustness and relevance. The findings indicate that all the studied variables significantly affect turnover intentions, with employee empowerment emerging as the strongest predictor, followed by work-life balance, and then reward systems. These results underscore the critical role of organizational culture in shaping millennial turnover intentions. The study’s insights can guide MNCs in Penang to implement strategic initiatives aimed at fostering a positive work environment that emphasizes empowerment, balance, and appropriate rewards, thereby enhancing employee retention within this pivotal demographic. While this study provides detailed insights specific to the Malaysian context, its findings may serve as a preliminary reference point for MNCs in similar regional contexts, suggesting further research to explore the applicability of these insights globally.

Combined effects of functional task training with electrical stimulation on motor abilities and balance in children with diplegia

BackgroundChildren with spastic diplegic cerebral palsy (CP) often demonstrate gluteus medius weakness that causes balance deficits and frequent falling during walking.PurposeThe aim of the study was to evaluate the combined effects of functional task training with electrical stimulation of bilateral hip abductor muscles on motor abilities (standing and walking) and balance in children with spastic diplegic CP.MethodsThirty children with diplegic CP of both sexes whose ages ranged from 7 to 10 years were assigned randomly into two equal groups. For both groups, motor abilities were assessed by gross motor function measure (GMFM), and balance (static and dynamic) was assessed by the humac balance system before and after the study. The control group received a functional training program focusing on standing walking and balance exercises. While children in the study group received the same functional training program with bilateral electrical stimulation of gluteus medius muscles for 50 min. The treatment program for both groups was conducted for 3 sessions/week for 8 weeks.ResultsThere were statistically significant differences between the control and study group post-treatment in GMFM as well as the center of pressure test and weight shift test in favor of the study group (p < 0.05).ConclusionUsing functional task training with electrical stimulation for treatment of children with spastic diplegic CP have significant effects on improving their motor abilities and balance that suggests using it in rehabilitation for these children.

Особенности налогообложения разработки минерально-сырьевых ресурсов: мировой и отечественный опыты

Building a balanced system for obtaining a fair share of resource rents is one of the central objectives for the governments in the countries, rich in mineral resources. The special attention is paid to the high-margin projects on extraction of the hydrocarbon raw materials. Thus, the state share in the exploitation of its natural resources includes a variety of components, type and scope of which are determined by the specific conditions of a mining project. The article reviews the main tax instruments used in development of the mineral deposits, also considers the main trends in development of the international tax systems and their reflection in the Russian practice. It is shown that the main directions of the fiscal policy include simplification and striving for simplicity of administration, transparency in contracts between investors and governments, focus on transfer price issues, transition from gross royalties to taxation of economic results. Peculiarities of the budget policy in Russia determine development of agreements between the governments of the mining regions and mining companies aimed at the infrastructure and social facilities development, as a form of indirect natural rents for the development of the territories and local communities.

Physical qualities of acid sulfate soil: its limitations and implications for oil palm production

ABSTRACT Global demand has pressured the extension of oil palm production areas in Thailand to acid sulfate soils. Besides their severe acidity and nutrient imbalance, the soil physical quality is expected to restrict production. This research defined the critical physical limitations of acid sulfate soils for oil palm production. The soil parameters of physical quality were assessed, covering 32 points in both the topsoil (Ap) and subsoil horizons. These parameters consisted of penetration resistance in the wet and dry seasons, saturated hydraulic conductivity (Ksat), bulk density (BD), the water characteristic curve, available water capacity (AWCA), available water content (AWCO), infiltration, and the S-index (a single indicator of soil physical quality derived from the parameters of the van Genuchten equation). The results showed critical physical quality constraints, particularly concerning the S-index and water shortage. The poor physical quality was more distributed in the Ap horizon (S-index = 0.024) than in the subsoil (S-index = 0.033). The penetration resistance was moderately restricted (3.26 Mpa) to the plant roots only in the dry season. Corresponding to the S-index data, the Ap horizon had a lower AWCA (0.21) than the subsoil (0.30). Most negative AWCO values in the subsoils (78%) during the wet season suggested a severe water shortage for oil palm production. Further research is needed to refine a specific partial drainage technique under oil palm canopies, focusing on the air-water balance system.

Reliability analysis and preventive maintenance policy for consecutive k$k$‐out‐of‐n:F$n: F$ balanced system under failure criterion operating in shock environment

AbstractThis paper presents a consecutive ‐out‐of‐: balance system in a shock environment, where the state transition of component is induced by external shocks. If a predetermined threshold number of effective shocks are applied to component in a critical state, the component will fail. The state of the system is defined by the number of consecutive failing component groups in the system, which leads to system failure when a critical number of consecutive failing components is reached. To minimize maintenance costs, we propose a preventive maintenance method with an optimization model. We use finite Markov chain imbedding and Phase‐type distribution to calculate component group failure rates and associated probability functions in discrete and continuous time, respectively. The validity and accuracy of the model are confirmed by numerical examples and Monte Carlo simulations.

A morphometric comparison of the ductus reuniens in humans and guinea pigs, with a note on its evolutionary importance.

The mammalian inner ear contains the sensory organs responsible for balance (semicircular canals, utricle, and saccule) and hearing (cochlea). While these organs are functionally distinct, there exists a critical structural connection between the two: the ductus reuniens (DR). Despite its functional importance, comparative descriptions of DR morphology are limited, hindering our understanding of the evolutionary diversification of hearing and balance systems among mammals. Using virtual 3D models derived from micro-CT, we examine the morphology of the DR and its relationship to the bony labyrinth in humans compared to that in a commonly used animal model, the guinea pig. Anatomical reconstructions and univariate measurements were carried out in the software 3D Slicer. Data indicate similarities in DR morphology between humans and guinea pigs in terms of overall shape. However, there are considerable differences in relative DR length and width between humans and guinea pigs. Humans possess a relatively shorter and narrower DR but with wider openings to the saccule and cochlear duct. This results in a relatively more constricted DR lumen in humans which may differentially limit fluid transfer between the saccule and cochlea. Our results reveal previously hidden morphological diversity in the communication between the hearing and balance systems of the mammalian inner ear which may indicate alternative strategies for isolating the Organ of Corti from the peripheral vestibular system throughout mammalian evolution.

P-385 Personalized immunotherapy in RIF patients with different endometrial immune profiles

Abstract Study question Does immunotherapy effective in patients with recurrent implantation failure (RIF) according to the type of endometrial immune profile? Summary answer Immunotherapy based on the profile of the endometrial immune system has significant results in increasing the pregnancy rate and live birth rate. What is known already Personalized medicine in the area of infertility is in its early stages, and considering the promising results of personalization of treatment in other disorders, including cancer, it is expected to have acceptable results in infertility as well. Given that one of the key factors that affects the infertility of RIF patients is the imbalance of the endometrial immune system, efforts have been made to correct this disorder to increase the chances of fertility. Studies have classified RIF patients into different groups based on endometrial immune system profiles: Balanced, High, Low, and Mixed endometrial immune system activity. Study design, size, duration The study selected 267 RIF patients who were referred to Valiasr Hospital in Tabriz from Aug 2020-Sep 2023, and divided them into five groups: unclassified RIF patients (n = 89), patients with normal and balanced endometrial immune system profile (n = 63), and patients with high (n = 53), low (n = 38) and mixed (n = 24) profiles of endometrial immune system. Based on type of disorder identified, the appropriate immunotherapy was suggested for each group, including vaginal probiotics, lymphocyte therapy and Tacrolimus. Participants/materials, setting, methods The study classified RIF patients based on the endometrial immune system profiles, by the gene expression level of IL-18, IL-15, TWEAK, Fn-14, and CD56. The study included a group of unclassified RIF patients, who underwent routine IVF/ET cycles without immunotherapy. The Balanced group received no immunotherapy. For the Low endometrial immune group, probiotics and lymphocyte therapy were used. High group received probiotics and Tacrolimus, and for Mixed group, probiotics, Tacrolimus, and lymphocyte therapy were used. Main results and the role of chance The primary and secondary endpoints of this study were clinical pregnancy and delivery of a live born infant, respectively. The results showed that RIF patients without classification based on the profile of the endometrial immune system who went through the routine process of IVF/ET cycles had a 25.8% and 23.5% pregnancy and live birth rates, respectively. The pregnancy and live birth rates of the Balanced group was 28.5% and 25.3% (P=NS) while it was significantly higher in the High (56.6%, 54.7%), Low (47.3%, 44.7%) and Mixed groups (37.5%, 29.1%), respectively. According to the obtained results, it was found that the appropriate immunotherapy treatment based on the endometrial immune activity profiles in RIF patients has significantly increased the effective implantation rate in the IVF/ET cycles (P &amp;lt; 0.05). Limitations, reasons for caution It is necessary to examine a larger number of patients. Further work is needed to explore other parameters that are affected by endometrial immune system disorder and that can help classify RIF patients and recommend the most effective treatment. Wider implications of the findings For RIF patients, accurate identification of the cause of the disorder can be very effective for choosing the best treatment method. Personalized immunotherapy for RIF patients with immunologically abnormalities can lead to very promising and acceptable results while having few complications.

A staging table of Balkan crested newt embryonic development to serve as a baseline in evolutionary developmental studies.

There is an increased interest in the evolution and development of newts from the genus Triturus because: (1) morphological differentiation among the nine constituent species largely corresponds to different ecological preferences, (2) hybridization between different species pairs has various evolutionary outcomes in terms of life history traits and morphology, and (3) the genus expresses a balanced lethal system that causes arrested growth and death of half of the embryos. These features provide natural experimental settings for molecular, morphological, and life-history studies. Therefore, we produce a staging table for the Balkan crested newt (T. ivanbureschi). We provide detailed descriptions of 34 embryonic stages based on easily observable and interpretable external morphological characters, to ensure reproducibility. Compared with previous staging tables for Triturus, we include a vastly increased sample size and provide high-resolution photographs in lateral, ventral, and dorsal view, complemented by videos of specific developmental periods, and accompanied by detailed explanations on how to delineate the specific stages. Our staging table will serve as a baseline in comparative studies on Triturus newts: an emerging model system in evolutionary and developmental studies.

Acute and Acclimated Effects of Wearing Compression Garments on Balance Control in Community-Dwelling Older Adults.

Falls are very serious health concerns among older adults. Providing additional cutaneous and proprioceptive feedback to older adults may enhance their balance control and therefore reduce the incidents of falls. This study aimed to investigate the acute and acclimated effect of wearing waist-to-above-ankle compression garments (CGs) on balance control in community-dwelling older adults. Thirty-one older adults participated in the study. The Timed Up and Go, Berg Balance Scale, and the Fall Risk Test of the Biodex Balance System were used in a random order to examine balance control in three testing sessions 1week apart. Results indicated wearing CGs had a significant impact on the Timed Up and Go test (p < .001), Berg Balance Scale (p = .001), and the Fall Risk Test (p = .001). For the Timed Up and Go test, participants exhibited significant improvement in both the acute (8.68 vs. 7.91s) and acclimated effect (7.91 vs. 7.41s) of wearing CGs. For the Berg Balance Scale, participants showed significant improvement after wearing CGs for 1week in comparison to the no CGs condition (55.77 vs. 55.39 points). For the Fall Risk Test, participants showed a significant improvement in the acute effect of wearing CGs in comparison to the no CGs condition (1.55° vs. 1.31°). This exploratory study showed that wearing waist-to-above-ankle CGs provided a positive impact on balance control in healthy community-dwelling older adults. It lays the foundation for future studies with a larger sample size to investigate the potential benefits of wearing CGs in individuals with balance control deficits and/or other comorbidities.

State-of-Charge Estimation of Reconfigurable Supercapacitor

Abstract A large body of research has been done on state-of-charge (SOC) estimate of supercapacitors in the literature; most of the works have been on SOC estimation of individual supercapacitor units. Nonetheless, supercapacitors are usually linked to balancing circuits in real-world applications in order to remove inter-cell imbalances. The cells’ system dynamics shift to a new mode when the balancing circuit is turned on, making the SOC calculation techniques that are currently in use inappropriate. Our proposal in this research is a Kalman filtering-based reconfigurable supercapacitor balancing system SOC estimate method. By fusing a reconfigurable balancing circuit with the equivalent circuit model of supercapacitors, we create a linear switching systems model. The switching system’s discrete-time form is shown, and its observability is examined. With filter gains dynamically modified according to the system mode, a switching Kalman filter is intended to estimate the SOC of the switched system. The accuracy of SOC estimation is greatly improved by the suggested method when supercapacitors are in the balancing mode, as confirmed by the simulation results.

Capital deepening and land average grain yield convergence: Evidence from China

The shift of agricultural labor force to non-agricultural sectors has paralleled China's economic development, leading to a substantial rise in labor costs relative to capital. Consequently, the agricultural production has witnessed a shift towards capital-intensive practices. The capital deepening coincides with the significant increase in China's grain output while the main cause of capital deepening in China's grain production is poorly understood. This study examines the effect of increasing in various capital investments on the grain yield growth and growth convergence in China's main production areas, based on the data collected from the data set of the Compilation of Cost-Benefit Data of Agricultural Products (CCBDAP). Results show that the increases of chemical fertilizer, pesticide and machinery input have played key roles in the increase of grain yield. For early indica rice, japonica rice, wheat and maize, the average land output bears a β convergence. These findings suggest that more capital investments are supposed to accelerate the growth of grain yield per unit of land, take the opportunity of practicing the cross-provincial balance system of occupation and compensation of cultivated land. Moreover, strategic adjustments to the spatial distribution of grain cultivation are recommended to maximize the utilization of limited arable land resources while upholding national food security objectives.

Estimation of Evapotranspiration in South Eastern Afghanistan Using the GCOM-C Algorithm on the Basis of Landsat Satellite Imagery

This study aims to assess the performance of the Global Change Observation Mission—Climate (GCOM-C) ETindex estimation algorithm to estimate the actual evapotranspiration (ETa) in southeastern Afghanistan. Here, the GCOM-C ETindex algorithm was adopted to estimate the monthly ETa for the period from November 2016 to October 2017 using a series of Landsat 8, Thermal Infrared Sensor (TIRS) Band 10 satellite imagery. The estimation accuracy was evaluated by comparing the results with other estimates of ETa, namely the mapping evapotranspiration with the internalized calibration (METRIC) model, the MODIS Global Evapotranspiration Project (MOD16), the surface energy balance system (SEBS) tools, and with the crop evapotranspiration under standard conditions (ETc) as estimated by the FAO-56 procedure. The evaluation was made for irrigated wheat, maize, rice, and orchards and for non-irrigated bare soil land. The comparison of ETa values showed good correlation among the GCOM-C, METRIC, and FAO-56, while the MOD16 and SEBS showed significantly lower values of ETa. The agreement with the METRIC ETa implies that the simple GCOM-C algorithm successfully estimated the ETa in the region and that the precision was similar to that of the METRIC. This study provides the first high-quality evapotranspiration data with the spatial resolution of Landsat Band 10 data for the southeastern part of Afghanistan. The estimation procedure is straightforward, and its results are anticipated to enhance the understanding of regional hydrology.

High Performance Balanced Linear Polarization Photodetector Based on 2D ReS2

AbstractConventional research on linear polarization photodetector for 2D materials has focused on the search for different anisotropic materials, combinations between materials, introducing plasmonic structures, and patterning 2D materials to improve performance. However, these methods provide limited improvement in polarization sensitivity. Here, a balanced photodetector structure is proposed that does not require an additional process and relies only on the presence of anisotropy in the material itself to substantially improve the polarization sensitivity. The balanced photodetector consists of two ReS2 photodetectors, where the single ReS2 photodetector exhibits excellent performance at 650 nm illumination, including a responsivity and detectivity of 0.28 A W−1 and 4.22 × 109 Jones. Benefiting from the anisotropy of ReS2, the single photodetector achieves excellent polarization sensitivity of 2.79 at 650 nm. The balanced photodetector system achieves an excellent performance of ≈20 dB linear polarization extinction ratio and 0.003° Hz−1/2 noise equivalent light polarization difference at 100 kHz. These performances can also be further optimized by adjusting the gate voltage. The results provide a basis for further development of high‐performance polarization photodetector for 2D materials.

INTERACTION OF THE JUDICIARY AND THE PRESIDENT OF THE REPUBLIC OF KAZAKHSTAN

The work is devoted to studying the issue of interaction between the judicial branch of government and the highest official of the President of the Republic of Kazakhstan. The areas of activity in which the judiciary and the President interact are identified. Among the important and fundamental ones, the sphere of human rights and freedoms is highlighted, in which the Court and the President, as elements that make up the mechanism of the state, closely interact with each other in providing guarantees of constitutional rights and freedoms of the individual and providing them with judicial protection. Particular attention is paid to the constitutional powers of the courts to exercise judicial control regarding the compliance of acts of the President with the Constitution and the laws of the republic, as well as the administration of justice in criminal cases. Similarly, attention is drawn to the constitutional powers of the President to issue an act of pardon for a person convicted by the court, as well as to deprive him of an honorary, military, special or other rank, class rank, diplomatic rank, qualification class, and state awards. The view is focused on the special procedure for implementing the constitutional and legal responsibility of the President and the termination of the constitutional powers of judges. The legislation and judicial practice of the Russian Federation in the issues raised are covered. The regulatory legal acts of the Republic of Kazakhstan defining the constitutional status and powers of the courts and the President were analyzed. Upon completion of the work, brief conclusions are given, arguing that courts and judges, firstly, when exercising their constitutional powers, have both external and internal independence, and secondly, they interact with all government bodies and officials, including the President, in strict adherence to the system of checks and balances that do not allow them to violate the unity of state power itself, its usurpation or concentration.
