OBJECTIVE

Hyperextension of C0–2 is a debilitating compensatory mechanism used to maintain horizontal gaze, analogous to high pelvic tilt in the lumbopelvic complex to maintain an upright posture. This study aims to investigate the impact of cervical deformity (CD) correction on this hyperextension. The authors hypothesize that correction of cervical sagittal malalignment allows for relaxation of C0–2 hyperextension and improved clinical outcomes.

METHODS

A retrospective review was conducted of a multicenter database of patients with CD undergoing spinal realignment and fusion caudal to C2 and cephalad to the pelvis. Range of motion (ROM) and reserve of extension (ROE) were calculated across C2–7 and C0–2. The association between C2–7 correction and change in C0–2 ROE was investigated while controlling for horizontal gaze, followed by stratification into ΔC2–7 percentiles.

RESULTS

Sixty-five patients were included (mean age 61.8 ± 9.6 years, 68% female). At baseline, patients had cervical kyphosis (C2–7, −11.7° ± 18.2°; T1 slope–cervical lordosis mismatch, 38.6° ± 18.6°), negative global alignment (sagittal vertical axis [SVA] −12.8 ± 71.2 mm), and hyperlordosis at C0–2 (mean 33.2° ± 11.8°). The mean ROM was 25.7° ± 17.7° and 21.3° ± 9.9° at C2–7 and C0–2, respectively, with an ROE of approximately 9° for each segment. Limited C0–2 ROM and ROE correlated with the Neck Disability Index (r = −0.371 and −0.394, p < 0.01). The mean number of levels fused was 7.0 ± 3.1 (24.6% anterior, 43.1% posterior), with 87.7% undergoing at least an osteotomy. At 1 year, mean C2–7 increased to 5.5° ± 13.4°, SVA became neutral (11.5 ± 54.8 mm), C0–2 hyperlordosis decreased to 27.8° ± 11.7°, and thoracic kyphosis (TK) increased to −49.4° ± 18.1° (all p < 0.001). Concurrently, mean C0–2 ROM increased to 27.6° ± 8.1° and C2–7 ROM decreased significantly to 9.0° ± 12.3° without a change in ROE. Controlling for horizontal gaze, change in C2–7 lordosis significantly correlated with increased TK (r = −0.617, p < 0.001), decreased C0–2 (r = −0.747, p < 0.001), and increased C0–2 ROE (r = 0.550, p = 0.002).

CONCLUSIONS

CD correction can significantly impact cephalad and caudal compensation in the upper cervical and thoracic spine. Restoration of cervical alignment resulted in increased C0–2 ROE and TK and was also associated with improved clinical outcome.

Authors: Gerasimenko S.S. , Nosova E.A.
Published: May 2022

The article, based on the theoretical foundations of statistical management, considers the tasks, the solution of which should contribute to obtaining the information necessary for the effective functioning of the market segment. Its effective functioning means achieving a balance between supply and demand, which should result from the collection, processing and use of objective, meaningful and operational data on effective customer demand and their use for management decisions by manufacturers to meet it. It is noted that the formation of such information support market analysis requires taking into account the specific characteristics of the participants of its individual segments, which sells a particular product for certain categories of buyers. This requires prior market segmentation and the development of its own system of statistics for each of them. After determining the set of indicators whose knowledge of the level and trends should contribute to the justification of management decisions, there is a task of finding a data source. In the context of digitalization of society, in addition to the data of the State Statistics Service, electronic sources provide great assistance in this. However, they also have certain shortcomings, which cause significant risks in decision-making based on the results of the analysis for which such data were used. Taking into account the above remarks, the article proposes to carry out its segmentation, to develop the necessary system of statistical indicators to assess the attractiveness and analysis of the situation of a certain segment, to identify data sources to calculate the level and track trends, identify ways to further change on business entities involved in the market, in order to obtain competitive advantages.
A Framework for the Assessment of Fiscal Consequences of Global Trade Wars
Authors: Bilousova O. S.
Published: May 2022

The article is devoted to topical issues of assessing the consequences of trade wars for the fiscal space of third countries. The main preconditions and causes of the trade conflict between the United States and China were studied. The main models for assessing the consequences of global trade wars were analyzed. Particular attention is paid to the global integrated monetary, fiscal and global trade models, which are based on the principles of general economic equilibrium and are widely used to assess the economic consequences of global challenges, including trade wars. It was found that the global integrated monetary and fiscal model, other macroeconomic models were aimed at determining the economic consequences and effects and cannot be directly used to assess fiscal risks and likely budget losses due to global trade wars. The aim of the article is to deepen the principles of assessing the fiscal consequences of trade wars in the conditions of uncertainty in foreign economic policy and directions of restructuring of the world value chains. The economic consequences of the conflict and the channels of their spread to third countries were identified taking into account the deepening globalization processes. The direct and indirect dependence of exports and imports, GDP, investments, factor productivity level and tax revenues on changes in foreign trade, tariff increases, increasing uncertainty in world trade in the short, medium and long term is highlighted. The estimates obtained by different models are summarized. The fiscal consequences of the trade conflict between the United States and China for Ukraine as a country with a small, open and predominantly commodity economy were quantified. The inclusion in fiscal risks of probable losses of foreign trade from global trade wars, arising due to various reasons, which may decrease the tax revenues or increase the expenditures on the public support of enterprises, is justified. Changes in the methodology for assessment of fiscal risks are proposed, enabling to estimate the cost impact of fiscal risks on the public budget of Ukraine. Proposals for improvements in the statistical monitoring of business activity of enterprises, to form an appropriate information base for monitoring foreign economic activities, assessing fiscal risks and making decisions to ensure the sustainability of public finance and public support for enterprises in the conditions of global trade wars, are substantiated.

Published: May 2022

The paper discusses the issues of improving students' media literacy skills to help them to navigate through an increasingly complex information so- ciety. It reports on a project aimed at applying the blended learning model to boost high school students' media literacy levels. The given model is recognized to have a number of advantages for both teachers (tutors) and learners (students). It is generally accepted that the blended learning method provides students with profound theoretical knowledge and retains the emphasis on practice. Besides, online classes offer a great opportunity to reach a wider audience. The purpose of the paper is to describe the authors' experience in introducing a new method for improving the learners' media literacy skills based on the blended learning model. The survey responses demonstrated that the accessibility, ease-of-use, and duration of the classes were deemed effective in terms of students' engagement and increases in their media literacy level. The course helped learners to develop their critical thinking and other media-related skills, to identify propaganda, ma- nipulation, and fake messages found in media streams.

Published: May 2022

This paper is discusses the problems of the short-term forecasting of financial time series using supervised machine learning (ML) approach. For this goal, we applied several the most powerful methods including Support Vector Machine (SVM), Multilayer Perceptron (MLP), Random Forests (RF) and Stochastic Gradient Boosting Machine (SGBM). As dataset were selected the daily close prices of two stock index: SP 500 and NASDAQ, two the most capitalized cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), and exchange rate of EUR-USD. As features we used only the past price information. To check the efficiency of these models we made out-of-sample forecast for selected time series by using one step ahead technique. The accuracy rates of the forecasted prices by using ML models were calculated. The results verify the applicability of the ML approach for the forecasting of financial time series. The best out of sample accuracy of short-term prediction daily close prices for selected time series obtained by SGBM and MLP in terms of Mean Absolute Percentage Error (MAPE) was within 0.46-3.71 %. Our results are comparable with accuracy obtained by Deep learning approaches.

The Origins of Japan’s Contemporary Diplomatic Strategy in East Asia: 2001–2012
Authors: Filippov Dmitry
Published: May 2022

Throughout the first decade of the 21st century, Japan’s East Asia policy saw the emergence of several new strategies and initiatives. The two key strategies of this period were the East Asian Community and the Arc of Freedom and Prosperity, which reflected differing approaches towards the role of China in the developing regional order. The goal of this article is to analyse the ideological foundations of these two strategies, as well as the reasons behind their failure. It also examines the question of why Japan’s diplomatic initiatives changed so rapidly during these years. Finally, the article looks at the shifts in Sino-Japanese relations which represent a key variable in the evolution of Japan’s East Asia policy. While Japan’s East Asian policy of this period is well researched in Russian academic literature, the majority of studies examine the policies of specific prime ministers, with Asian diplomacy typically viewed within the framework of foreign policy in general. Meanwhile, a more dynamic analysis of the development of Japan’s regional strategy is lacking, and it is this gap that this article attempts to fill. Based on the analysis of Japanese government documents, as well as a wide range of studies of Japan’s foreign policy by Russian and foreign scholars, from monographs and academic journals to online outlets, it presents the evolution of Japan’s strategy in East Asia as a competition between two foreign policy initiatives, the East Asian Community and the Arc of Freedom and Prosperity. The article also highlights the prime ministers’ personal views and beliefs, which had a significant effect on creating a particular strategy. The article concludes that the two aforementioned strategies were underpinned by different political philosophies, with the East Asian Community aiming to accelerate East Asian integration based on common economic interests and embracing China, while the Arc of Freedom and Prosperity prioritised relations with countries sharing Japan’s democratic values and viewed China as a regional outsider. It was precisely Sino-Japanese ties, however, that were perhaps the biggest reason why neither strategy achieved much success at the time; either Japan considered the bilateral relations too economically beneficial to deliberately alienate China, or they suffered from too much tension which precluded further development of economic relations.

Authors: Sittichok Ketvara , Vongphet Jutithep , Seidou Ousmane
Published: May 2022

Expected changes in temperature, rainfall, water yield and surface runoff dynamics under RCP 8.5 were estimated in the Phetchaburi River Basin, Thailand, using outputs of five regional climate models. Observed temperatures and precipitations were downscaled using a combination of quantile mapping and nearest neighbour methods. The SWAT model was used to estimate changes in hydroclimatic variables in both the near-term (2006-2050) and long-term (2051-2099) temporal frames. All models predicted higher temperatures in the future (28.7-30.4°C) compared to the historical situation (28.0-28.3°C). The patterns of maximum temperature from most models were shifted one month earlier but there was no significant change for minimum temperature. Disagreement between models could be found in projected precipitations for the short term, but most of them pointed to an increase in rainfall in the long term, especially for maximum rainfalls ranging from 1,637 to 1,947 mm. CNRM-CM5 presented large differences in the future rainfalls compared to other models. Surface runoff/water yield significantly increased by 14%/17% in the long-term following the same trend as rainfalls with a slight change in the short-term.
Sawdust as Low-Cost Adsorbents for the Removal of Heavy Metals From Water
Authors: Ahmaruzzaman Md.
Published: May 2022

Sawdust is currently investigated as a sorbent to eliminate heavy metals from wastewater and other aqueous solutions. The raw material is relatively cheap and is available in abundance. Sawdust also helps to eradicate other contaminants, such as dyes, pesticides, phenols, toxic salts, etc. This literature discusses the elimination of heavy metals from wastewater through the help of sawdust. The composition of the sawdust, and the work done concerning the sorption of heavy metals, kinetics, adsorption isotherm, etc., are discussed in this study. The adsorption capacity of sawdust depends on the concentration of adsorbate, composition and characterisation of adsorbent, and the type of modifications. Also, the challenges faced during research are mentioned in this literature. More research should be done in this field to enhance the use of sawdust on large-scale cost-effectively.

Published: May 2022

The continuous rise of industrial waste has a tremendous impact on communities and the environment of Thailand. The purpose of this study was to develop a Structural Equation Model (SEM) for industrial waste management in the industrial business sectors. Four aspects arranged in the order of importance were as follows: Process Management, Business Ethics, Technology and Innovation, and Participation respectively. The hypothesis test result showed that the Business Ethics directly influenced the Participation and the Technology and Innovation, the Technology and Innovation directly influenced the Participation and the Participation directly influenced the Process Management; all the four paths were at the statistical significant level of 0.001, the Technology and Innovation directly influenced the Process Management at the statistical significant level of 0.01. As a whole, no differences between industrial waste management for enterprises in and outside the industrial estates at the statistical significance level of 0.05. The analysis of SEM revealed that it passed the assessment criteria and was consistent with the empirical data. The chi-square probability level, the relative chi-square, the goodness of fit index, and the root mean square error of approximation were 0.089, 1.143, 0.961, and 0.017, respectively.
Household Solid Waste Management in a Developing World: An Overview
Authors: Datta Madhumita Ghosh
Published: May 2022

Households in developing countries are the primary waste generators. Therefore, this study aims to identify the composition and factors responsible for household solid waste generation. It also studies the current status of household waste management in India and strategies for waste minimisation and management. Findings revealed that household waste is heterogeneous. The urban household produces substantial amounts of waste, and vegetables and food waste are major components. Family size has either a positive or negative impact on waste generation. A higher-income household with more purchasing power has a clear positive impact on waste generation. People living together share food items and consumer goods, so fewer food scraps, leftovers, and packaging wastes are there. With advanced education, household wastes are higher, whereas households with secondary education produce the least waste. There is an accumulation of fresh graduates but few are aware of current environmental issues. Municipalities are responsible for collecting and disposing of solid waste, but at present, they focus mostly on the collection part, while innovation in waste treatment is scarce. Nevertheless, a few cities in India have taken a positive approach to the selection of waste management strategies. Also, household solid waste can be converted from burden to resource by sensitising people to segregate waste at the source and following sustainable strategies.
The Jacobson radical for an inconsistency predicate
Authors: Schuster Peter , Wessel Daniel
Published: May 2022

As a form of the Axiom of Choice about relatively simple structures (posets), Hausdorff’s Maximal Chain Principle appears to be little amenable to computational interpretation. This received view, however, requires revision: maximal chains are more reminiscent of maximal ideals than it seems at first glance. The latter live in richer algebraic structures (rings), and thus are readier to be put under computational scrutiny. Exploiting this, and of course the analogy between maximal chains and maximal ideals, the concept of Jacobson radical carries over from a ring to an arbitrary set with an abstract inconsistency predicate: that is, a distinguished monotone family of finite subsets. All this makes possible not only to generalise Hausdorff’s principle, but also to express it as a syntactical conservation theorem. The latter, which encompasses the desired computational core of Hausdorff’s principle, is obtained by a generalised inductive definition. The over-all setting is constructive set theory.
Primitive recursive equivalence relations and their primitive recursive complexity
Authors: Bazhenov Nikolay , Ng Keng Meng , San Mauro Luca , Sorbi Andrea
Published: May 2022

The complexity of equivalence relations has received much attention in the recent literature. The main tool for such endeavour is the following reducibility: given equivalence relations R and S on natural numbers, R is computably reducible to S if there is a computable function f : ω → ω that induces an injective map from R-equivalence classes to S-equivalence classes. In order to compare the complexity of equivalence relations which are computable, researchers considered also feasible variants of computable reducibility, such as the polynomial-time reducibility. In this work, we explore Peq, the degree structure generated by primitive recursive reducibility on primitive recursive equivalence relations with infinitely many equivalence classes. In contrast with all other known degree structures on equivalence relations, we show that Peq has much more structure: e.g., we show that it is a dense distributive lattice. On the other hand, we also offer evidence of the intricacy of Peq, proving, e.g., that the structure is neither rigid nor homogeneous.
Reverse triple I method based on the Pythagorean fuzzy inference model and its application
Authors: He Yanping , Nan TaiBen , Zhang Haidong
Published: May 2022

This paper is devoted to discussing the reverse triple I method based on the Pythagorean fuzzy set (PFS). We first propose the concepts of Pythagorean t-norm, Pythagorean t-conorm, residual Pythagorean fuzzy implication operator (RPFIO) and Pythagorean fuzzy biresiduum. The reverse triple I methods for Pythagorean fuzzy modus ponens (PFMP) and Pythagorean fuzzy modus tollens (PFMT) are also established. In addition, some interesting properties of the reverse triple I method of PFMP and PFMT inference models are analysed, including the robustness, continuity and reversibility. Finally, a practical problem is provided to illustrate the effectiveness of the reverse triple I method for PFMP in decision-making problems. The advantages of the new method over existing methods are also expounded. Overall, compared with the existing methods, the proposed methods are based on logical reasoning rather than using aggregation operators, so the novel methods are more logical, can better deal with the uncertain problems in complex decision-making environments and can completely reflect the decision-making opinions of decision-makers.
Uncertain support vector regression with imprecise observations
Authors: Li Qiqi , Qin Zhongfeng , Liu Zhe
Published: May 2022

Traditional support vector regression dedicates to obtaining a regression function through a tube, which contains as many as precise observations. However, the data sometimes cannot be imprecisely observed, which implies that traditional support vector regression is not applicable. Motivated by this, in this paper, we employ uncertain variables to describe imprecise observations and build an optimization model, i.e., the uncertain support vector regression model. We further derive the crisp equivalent form of the model when inverse uncertainty distributions are known. Finally, we illustrate the application of the model by numerical examples.
Bipolar interval-valued fuzzy set in graph and hypergraph settings
Authors: Gong Shu , Hua Gang
Published: May 2022

Graphs and hypergraphs are popular models for data structured representation. For example, traffic data, weather data, and animal skeleton data are all described by graph structures. Interval-valued fuzzy sets change the membership function of general fuzzy sets from single value functions to interval-valued functions, and thus describe the fuzzy attributes of things in terms of fuzzy intervals, which is more in line with the characteristics of fuzzy objectives. This paper aims to define the bipolar interval-valued fuzzy hypergraph to reveal the inner relationship of fuzzy data, and give some characterizations of it. The characteristics of bipolar interval-valued intuitionistic fuzzy hypergraph and bipolar interval-valued Pythagorean fuzzy hypergraph are studied. In addition, we discuss the characteristics of the bipolar interval-valued fuzzy threshold graph. Finally, some instances are presented as the applications of bipolar interval-valued fuzzy hypergraphs.
Fuzzy logic-based modeling and analysis of SBCNC-60 machine for turning operation of surface finish and MRR output
Authors: Saxena Arti , Dubey Y.M. , Kumar Manish
Published: May 2022

On the everlasting demand for better accuracy, high speed, and the inevitable approach for the high-quality surface finish as the basic requirements in the process industry, there felt the requirement to develop models which are reliable for predicting surface roughness (SR) as it is having a crucial role in the process industries. In this paper, SBCNC-60 of HMT make used to study the purpose of machining, while cutting speed (CS), feed rate (FR), and the depth of cut (DoC) were considered as parameters for machining of P8 material. Turning experiments data is studied by keeping two parameters constant at the mid-level out of three parameters. An artificial intelligence technique named fuzzy was engaged in working out for surface roughness and material removal rate (MRR) to design the models of reliable nature for the predictions. The accurate prediction performance of the fuzzy logic model was then better analyzed by calculating MAPE, RMSE, MAD, and correlation coefficient between experimental values and fuzzy logic predictions. MAPE, RMSE, MAD, and correlation coefficient calculated 2.66%, 8.20, 6.44, and 0.98 for MRR and 4.19%,1.16, 0.86 and 0.90 for SR, respectively. Hence, the proposed fuzzy logic rules efficiently predict the SR and MRR on P8 material with higher accuracy and computational cost.
Performance evaluation of IaaS cloud using Stochastic Neural Network
Authors: Kotteswari K. , Bharathi A.
Published: May 2022

Cloud computing is an on-demand model that computes shared and dynamic resource availability in a remote or independent location. Cloud computing provides many services online to clients in a pay-as-you-go manner. Nowadays, many organizations use cloud computing techniques with the prime motive that cost can be reduced, and resources are dynamically allocated. Performance evaluation and measurement approaches for cloud computing help the cloud services consumer to evaluate their cloud system based on performance attributes. Although the researchers have proposed many techniques and approaches in this direction in past decades, none of them has attained widespread industrial benefit. This paper proposes a novel quality evaluation methodology named Stochastic Neural Net (SNN) to evaluate the cloud quality of Infrastructure as a Service (IaaS). This model deeply measures the performance by considering every activity of the IaaS system. Based on their characteristics, these works suggest key QoS factors for individual parts and activities. The individual QoS metric makes the SNN methodology acquire accurate results regarding performance measurement. The performance evaluation result can be used to improve the cloud computing system. The proposed model is compared with other standard models. The experimental comparison shows that the proposed model is more efficient than other standard models.

Published: May 2022

The use of floors with hollow linersis one of the possible ways to reduce the materialconsumption and weight of buildings made ofmonolithic concrete, almost without reducing theirreliability. Reducing the weight of structures is animportant advantage in the construction of facilities in seismically active regions.However, the introduction of such plates inconstruction is constrained by the lack of theoretical research and the necessary regulatory framework and experience in designing these structures.The article considers the problems of calculations and construction of a lightweight monosummer floor on the example of a specific 18-storey residential building. The basic principlesand methods of construction and calculation ofhollow monolithic floors are given.The method of modeling a slab of reducedstiffness is the most expedient for the constructionof a spatial calculation model of a building withdifferent floor slabs.According to the results of the study, it wasfound that the hollow floor has advantages over thesolid typical in many parameters. The key differences are in the consumption of concrete -18.6%,the consumption of steel - 24.2% and the ownweight of the floor - 32.9%.Lightweight slabs are best suited for buildingswith large spans and low payloads, but their usewill be effective for buildings with large spans andsignificant payloads.

Como hemos visto en cuadernos anteriores, las investigaciones siempre necesitan de distintas técnicas para levantar información. Algunas de las que hemos descrito son la entrevista, la encuesta y fotovoz (¡Recuerda que hay muchas más!) Además, debes saber que una investigación puede ser: a) Temporal: son datos recogidos en distintas fechas para comprobar si los resultados son constantes en el tiempo, es decir, si se mantienen igual o van cambiando. b) Espacial: los datos recogidos se hacen en distintos lugares para comprobar coincidencias, similitudes.Una vez que ya hemos aplicado nuestras técnicas para recolectar información y obtuvimos datos, ¿qué debemos hacer con la información recogida? Tal como observas en el esquema, el siguiente paso es analizar los datos que hemos recolectado.

Bahan baku polipropilena (PP) memiliki cakupan luas dalam hal produk yang bisa dihasilkan, mulai dari alat-alat rumah tangga hingga industri. PP yang memiliki keunggulan dapat dibentuk ulang memberikan potensi pemakaian ulang bahan baku yang telah melalui proses pemanasan. Penelitian mengenai perbandingan sifat kekerasan dan penyusutan terhadap produk PP murni dan campuran PP yang telah mendapat pemanasan berulang sebanyak enam kali di dilakukan untuk melihat potensi penggunaannya. Hasil penelitian menunjukkan penurunan sifat kekerasan dan peningkatan penyusutan terjadi seiring penambahan komposisi PP hasil pemanasan ulang. Kekerasan PP 100% murni dibandingkan dengan PP 100% pemanasan ulang ke enam turun sebesar 5% yaitu dari 60,4 Shore D dan 57,4 Shore D. Penyusutan produk masih dibawah 2% baik arah panjang maupun arah lebar. Penyusutan pada arah panjang lebih besar dibandingkan arah lebar, pada produk PP murni terjadi penyusutan sebesar 1,43% pada arah panjang dan 1,35% arah lebar, sedangkan pada produk PP 100% pemanasan ulang arah panjang mecapai 1,65% dan arah lebar 1,61%. Penurunan ini menunjukan bahwa material PP yang telah melalui pemanasan berulang mengalami degradasi walaupun tidak signifikan. Perubahan sifat mekanik (kekerasan) dan fisik (penyusutan) ini sebagai pertimbangan dalam pemilihan bahan dasar murni atau campuran agar mendapatkan produk sesuai dengan spesifikasi dengan memanfaatkan bahan dari sisa produk yang tidak terpakai.

The increase in the human population, which continues to increase accompanied by the rate of conversion of agricultural land to non-agricultural land is increasingly causing a problem of food supply. Aquaponics is one solution to this problem, but conventional aquaponics treatment must be done manually and will require a lot of time and energy in caring for it if the land is large enough. The implementation of IoT technology can help in the aquaponics treatment. This research aims to create a control and monitoring system for aquaponic cultivation built in a greenhouse. The parameter to be controlled is the water level of the fish pond using an ultrasonic hc-sr04 sensor and a solenoid valve which functions to fill the water in the pond. While the parameters to be monitored are the water level and the pH of the fish pond water. Data from the sensor is sent using the HTTP protocol by the NodeMcu microcontroller to the database via the internet network. The results of this research indicate that the control system has been successfully created where the solenoid valve will turn on when the distance between the ultrasonic sensor and the pool water level is more than 50 cm. The results of water measurements are still fluctuating due to placement of ultrasonic sensors under the water pipe to the fish pond. Meanwhile, the monitoring system will present measurement data in the form of graphs where the data will be updated every 30 minutes.

The work is devoted to the analysis of legal norms of the current law of the International Financial Center “Astana» and the current law of the Republic of Kazakhstan, regulating civil relations on the territory of the International Financial Center «Astana». The relevance of the work is confirmed by the fact that the new Concept of the legal policy of the Republic of Kazakhstan until 2030 pays special attention to the development of the civil law industry, coupled with an emphasis on creating a favorable investment climate. The purpose of this work is to analyze the current law of the Center, adopted acts of the International Financial Center «Astana» in the field of civil law relations. In addition, the article discusses the issues of the action of the highest legal force of the Constitution of the Republic of Kazakhstan on the territory of the Center. The author identified two approaches: the first is the absoluteness of the constitutional postulate of the highest legal force of the Constitution on the territory of the Center. The second approach is to be somewhat limited, taking into account the special legal regime of the Center. Particular emphasis is placed on the operation of the acts of the Center in the field of civil legal relations. Based on the adopted acts of the Center, the author analyzes the possibility of applying collaborations of legal norms, including the norms of statutory and case law of England and Wales to regulate a specific legal relationship. At the same time, we believe that for another type of legal relationship, such an application is not provided for by the acts of the Center.

Within the framework of the current legal reforms, the streamlining of the rule-making system and the systematization of normative legal acts are of particular importance. An urgent issue remains the need to develop high-quality draft regulatory legal acts, adjust or cancel outdated norms, use foreign experience in norm-making. At the same time, the development of the national system of rule-making is impossible without taking into account the established scientific theories and ideas. Often, when developing legal norms, the principles of rule-making are declared, but they do not fill the provisions of a normative legal act with their content. There are isolated cases of appeal of bodies-developers of draft regulatory legal acts to fundamental scientific research, statistical data, and sociological research. As a result, the quality of regulations suffers, and conflicts and gaps arise. The article focuses on the issue of normative consolidation of the principles of rulemaking in the legislation of the Republic of Kazakhstan. The study is based on the study of the experience of post-Soviet countries. There are considered and analyzed the most common principles of rule-making. The article suggests measures to improve the national legislation in the field of rule-making activities, including by proving the need to introduce the principles of rule-making into the domestic practice of developing draft normative legal acts. At the same time, the emphasis is placed on the need to consolidate the principles of rule – making at the level of a legislative act - the Law of the Republic of Kazakhstan «On Legal Acts». This approach will make it possible to oblige all subjects of the rule-making process to use the principles of rule-making at the stage of developing a draft regulatory legal act.
