In this article, the conditions of invalidity of legal transactions and the consequences prescribed by the law are considered.

The article proposes a solution to the problem of goal-setting from the standpoint of activity and competency-based approaches. Concrete formulations of the goals and objectives of the academic disciplines "Methodology of Teaching Natural Sciences" and the school course "Natural Sciences" are given. The choice of these disciplines to illustrate examples of the formulation of the learning goal is determined by their specificity. Since in the course of “Natural Sciences”, students should learn the initial concepts of natural sciences (biology, geography, ecology, human physiology, history of society, etc.), the proposed examples of the wording of the goals and objectives of science lessons will help, according to the authors, teachers and other specialists in the field of education to formulate, by analogy, the goals of disciplines from other areas of science. The specificity of the school course "Natural Sciences" determines the specifics of the theory and technology of teaching this discipline. The wordings of the goals and objectives of the course “Methods of Teaching Natural Sciences” proposed by the authors are developed in accordance with the goals and objectives of the school discipline “Natural Sciences” in compliance with the logic of presentation, a sufficient degree of validity and convincing conclusions, as well as taking into account the specifics of the subject and the didactic principle of continuity.

Among many environmental conditions that affect a person, the most important factor is nutrition. Today, there is no doubt that there is a direct link between nutrition, health and disease. Proper nutrition ensures normal growth and development of a person, contributes to the prevention of diseases, has a positive impact on life expectancy and creates conditions for adaptation to the environment. A very actual topic for public catering in the Republic of Kazakhstan, namely for fast food companies, is the development of new recipes and culinary products from relatively inexpensive vegetable raw materials, as well as qualitatively new food products with a purposefully changed chemical composition. One of the main ways of solving problems of expanding the production of products for quick service, as well as products for dietary and therapeutic and preventive nutrition is the use of sprouted grains and beans. In this article, poly-grain mixtures of sprouted wheat and extruded soy beans in different ratios are studied and considered. Poly-grain mixtures developed by us are balanced in nutrients, vitamins and amino acids. The research was carried out on the basis of the accredited testing laboratory of RUBICOM enterprise LLP and the scientific laboratory of the Innovative Eurasian University. The purpose of this work is to study a promising method for increasing the nutritional value of grain mixtures by extruding them at different temperature conditions. To achieve this goal, the following tasks were planned: – to study the grain of soy beans and sprouted wheat on the organolepti c characteristics and chemical composition of the poly-grain mixture; – examine the chemical composition of the poly-grain mixture before extrusion; – choose the optimal mode of the extrusion process; – study and analyze the chemical composition of poly-grain extruded mixture; It should be noted that we have developed for the first time the optimal technological mode of extrusion of poly-grain mixture from sprouted wheat and soy beans, and the physical and chemical composition of the poly-grain mixture was studied. The results of the research presented in this paper are the basis for the development of recipes and technologies for fast food products. The reliability and validity of scientific statements is confirmed by the choice of modern methods of chemical composition analysis.

In this article, the author examines the grounds and principles of criminalization of encroachments against the personal freedom of a person and a citizen. The purpose of this study is to analyze the legal validity of criminalization of acts that infringe on personal freedom. The article emphasizes that the criminalization of socially dangerous acts taking place in society plays a leading role among the means of influencing crime. In the practice of developing criminal legislation, there are many examples when previously unpunished criminal acts were later recognized as a crime at the legislative level. The methodological basis of the research is based on traditional general scientific and special legal methods: system-structural, historical-legal and comparative-legal. The researcher notes that the need to criminalize crimes against personal freedom is primarily due to the following reasons: a high degree of public danger; negative dynamics of these acts; the existence of conditions for committing these crimes that cannot be eliminated without criminal liability; the need for a criminal law guarantee of protection of constitutional rights and legislative provisions; the existence of international legal obligations of the state to counteract the acts in question. Subsequently, the article makes a reasonable conclusion that in the Republic of Kazakhstan, in fact, there were and is currently objective grounds that prompted the legislator to criminalize attacks on personal freedom. The author refers to the principles of criminalization of acts against personal freedom: legal and criminological (the possibility of influencing socially dangerous acts through criminal law measures; the procedural feasibility of prosecution; the principle of proportionality of sanctions and economy of repression); socio-economic (the significant nature of the material and moral harm caused by the crime; the advantage of positive consequences over negative ones; the availability of material resources for the implementation of the criminal law ban; ); socio-psychological (sufficient level of public legal awareness and psychology; historical traditions). In the article, the author concludes that the Kazakh legislator really had every reason to criminalize acts against personal freedom. At the same time, it is emphasized that despite the relative regularity of criminal law acts that infringe on personal freedom, the legal regulation of criminal liability for them still requires further improvement.

Main problem: It is very important for each company to obtain an industrial certificate, which makes it possible to get into the Register of Domestic Manufacturers, as they expect to receive large orders. With the receipt of an industrial certificate, their prospects for participation in various tenders and purchases will significantly increase, where they can show their abilities, compete with domestic producers, and also have an advantage over importers. Since July 1, 2019, the industrial certificate has become mandatory for participation in public procurement. Corresponding changes to the rules for public procurement were made by the Ministry of Finance of the Republic of Kazakhstan. Taking into account the experience of the «Rules for determining the country of origin of goods, issuing a certificate of origin of goods and canceling its validity», approved by Order of the Acting Minister for Investment and Development of the Republic of Kazakhstan dated February 24, 2015. No. 155», it becomes clear that the document does not take into account a number of «narrow» specifics of individual industries. Purpose: development of amendments and additions to the «Rules for the formation and maintenance of the register of domestic producers of goods, works and services, as well as the issuance of an Industrial Certificate» for the subsequent possibility of obtaining an Industrial Certificate by a chemical industry enterprise for the production of mineral fertilizers. Methods: study and analysis of literary sources, statistics and modeling of the procedure for issuing an Industrial Certificate. Results and their significance: the problems of application were studied, ways to solve these problems were found, and amendments and additions to the “Rules for the formation and maintenance of the register of domestic producers of goods, works and services, as well as the issuance of an industrial certificate” were developed. At the moment, the Rules need to be carefully finalized. It is necessary to consider this issue together with authorized state bodies, associations and business representatives, since obtaining an Industrial Certificate will directly affect participation in public procurement, and, accordingly, the economy of the Republic of Kazakhstan.

Main problem: The article highlights the problem of tests as methods of psychology, the influence of validity and reliability on the results of psychological research. Purpose: Uncovering the significance of validity and reliability on psychological research results. Results and their significance: Testing is an important method in psychology, allowing measuring various aspects of the psyche and behavior of a person. The history of the development of tests in psychology goes back more than a century and began with the work of Francis Galton and Alfred Binet. Over time, the tests have become widely used in various fields such as education, personnel selection, clinical diagnosis and research. Basic requirements for tests include reliability (repeatability of results), validity (measurement accuracy), standardization (same test conditions) and objectivity (lack of subjectivity in assessment). Tests must be designed using psychometric principles to ensure accuracy and validity of results. Modern tests include a variety of measurement techniques, such as tests of personality, intelligence, aptitude, and professional skills. The use of tests in psychology requires professional training to correctly interpret the results and make valid conclusions. Testing as a method of psychology continues to evolve, and its role remains key in the study of the human psyche and behavior. Testing in psychology has a wide range of applications, including assessing personality traits, identifying psychological disorders, and predicting behavior and success in various areas of life. The development of computer-based tests and online platforms makes testing more efficient and convenient for researchers and participants. Modern tests increasingly take into account cultural differences and the diversity of individual characteristics, which contributes to more accurate and tailored assessments. It is important to remember that the use of tests requires ethics, confidentiality and compliance to ensure the reliability and validity of the data obtained.
