This novel approach, intended for incorporation into Kazakhstan’s grant framework, involves a two-tiered examination process – an initial assessment by the National Center for State Scientific and Technical Expertise (NCSTE) followed by a secondary review by the National Scientific Councils (NSC). The rationale behind this shift away from an overemphasis on quantitative and qualitative project details towards a qualitative, semantic, conceptual, and methodological representation is rooted in the constraints of NCSTE/NSC resources and other pertinent factors. We have adopted and tailored the Technology Readiness Level (TRL), Manufacturing Readiness Level (MRL), and Capability Readiness Level (CRL) scaling methodologies for R&D and RNTD activities by devising a novel Scientific Readiness Levels (SRL) methodology. This has resulted in the compilation of SRL scales for fundamental (FRL), applied (ARL), and innovative projects (IRL), bringing economic efficiency to the grant funding evaluation process.","PeriodicalId":51923,"journal":{"name":"Economic Annals-XXI","volume":"457 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135827769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These children are actively engaged in the ethno-intellectual sport of Togyz Kumalak which from an ethnohistorical perspective is a part of the socio-cultural heritage of the nomadic societies of Central Asia. Spanning a timeframe of 12 months, this multi-faceted study was articulated in a three-stage design framework. The initial stage involved a baseline assessment of the children’s nutritional statuses, utilizing anthropometric measurements and dietary recall surveys as empirical tools. Medical experts and biologists collaborated to identify the economic implications of nutrient imbalances that could lead to metabolic disorders and subsequent healthcare costs. The second stage encompassed the formulation and execution of nutritional interventions that were economically vetted for sustainability and impact. These interventions were derived from the baseline data and involved dietary supplementation, counseling, and a well-balanced nutritional regimen designed in consultation with coaches, trainers, and parents. During this stage, economic considerations were central to the discourse as experts across disciplines expounded on the optimal ratio of vital macro- and micronutrients, adequate caloric content, and even distribution of nutrients throughout the day. Such a comprehensive approach to diet structuring amplifies the economic viability by elucidating how a balanced nutritional intake can enhance athletic and intellectual performance, impact competition outcomes positively, and improve post-training recovery – thereby potentially mitigating of long-term healthcare expenditures. The study culminated in a rigorous post-intervention assessment that employed both cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA) methodologies. The results revealed not only a statistically significant improvement in the nutritional statuses of the children but also confirmed the cost-effectiveness and scalability of the interventions implemented. The economic aspects were augmented by metrics that interlinked the immediate benefits of the interventions with broader economic considerations, such as the potential reduction in healthcare-related costs over time. Research contributes profoundly to public health dialogues, offering insights into the optimization of resources to heighten the general well-being and performance, particularly in the specialized arena of ethno-intellectual sports like Togyz Kumalak. It successfully straddles the crossroads of health economics, cultural sports, and public health, emphasizing the potential for integrative approaches in the amelioration and proliferation of community-centered health programs. This multifaceted economic analysis thus serves as a robust model for scalable and economically viable public health strateg","PeriodicalId":51923,"journal":{"name":"Economic Annals-XXI","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135827771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is based on the analysis of the fatty acid composition of the product, which is a key factor influencing its consumer properties and production cost. The main economic aspect of this research is that the use of vegetable oils in spread production allows for a reduction in raw material costs, as they are usually cheaper than butter. This, in turn, can lead to a decrease in the final product cost and an increase in its market competitiveness. During the study, two samples of the product were selected for analysis of their fatty acid composition using gas chromatography. The results showed that with the addition of vegetable oils, the content of polyunsaturated fatty acids in the spread composition ranged from 2.271±0.114% to 12.421±0.621%. This indicates a high level of product balance, which can also contribute to its consumer appeal. The article also focuses on determining the optimal technological parameters for obtaining a high-quality product. The recommended parameters (temperature of 34°C, speed of modes ranging from 110 rpm to 150 rpm) allow for the production of a homogeneous emulsion without visible separations, which can also reduce production costs and improve product quality. The results of this study can be used by cream vegetable spread manufacturers to optimize the production process and improve economic efficiency.","PeriodicalId":51923,"journal":{"name":"Economic Annals-XXI","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135827646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology involves employing Hofstede’s dimensions – Power Distance, Individualism versus Collectivism, Masculinity versus Femininity, Uncertainty Avoidance, and Long-Term versus Short-Term Orientation – as a heuristic tool to evaluate the attributes of scientific culture in Kazakhstan. In this way, we shed light on how scientists in Kazakhstan interact with the prevailing cultural norms and expectations, offering a detailed view of culturally embedded scientific practices. To clarify, the five dimensions are adapted in the following manner: Firstly, Scientific Power Distance pertains to the degree of hierarchical authority within scientific institutions. High power distance in this setting implies a significant disparity between junior and senior researchers, thereby affecting the dynamics of collaboration and innovation. Secondly, Scientific Individualism-Collectivism measures the extent to which the scientific culture either fosters individual achievement and originality or prioritizes group cooperation. Thirdly, Scientific Masculinity-Femininity assesses the predominance of either competitive (Masculine) or collaborative (Feminine) traits within the scientific community. Fourthly, Scientific Uncertainty Avoidance deals with the community’s tolerance for uncertainty and ambiguity, indicating whether there’s a preference for structured environments. Lastly, Scientific Long-Term Orientation gauges the focus of scientific endeavors, whether they aim for immediate outputs or invest in long-term research. The Kazakhstan scientific system is thus situated within this adapted framework of five dimensions, providing an intricate mapping of how cultural attributes impact scientific pursuits in the country. The importance of cultural phenomenology in the scientific domain comes from its focus on the observation and interpretation of the cultural factors that influence scientific thinking, progress, and implementation. It recognizes that science is not an isolated activity but is deeply entrenched in societal and cultural systems. In the specific context of Kazakhstan, a country experiencing rapid socio-economic changes, the scientific system is not only shaped by various facets of cultural identity but also makes substantial contributions to socio-economic development. Regarding the empirical findings of this study, the data illustrates the profound economic impact of the scientific system in Kazakhstan. From increased R&D investment to job creation and attracting significant Foreign Direct Investment (FDI), the scientific system appears to make a direct and meaningful contribution to the nation’s economic growth and development.

This is driven by the dual goals of improving public health outcomes and stimulating economic growth. Dairy products, a staple in the Kazakh diet, have been identified as a key sector for development. However, the domestic dairy industry faces significant economic challenges. Firstly, the industry is in its nascent stages of recovery following a prolonged period of economic stagnation. Secondly, high-quality domestic dairy products are facing stiff market competition from inexpensive foreign imports, which often do not meet the necessary quality and nutritional standards. This has implications for both public health and the economic viability of domestic dairy producers. Thirdly, the country is at the initial stages of exploring combined technologies to produce dairy products enriched with herbal supplements, known as combined dairy products. This emerging sector represents a potential avenue for economic diversification and value addition within the dairy industry. The objective of the study outlined in the provided paper is multifaceted, encompassing economic, technological, and public health dimensions within the context of Kazakhstan’s domestic dairy industry. Specifically, the study aims to explore the economic potential and viability of producing combined cheeses with intermediate moisture content. To achieve this objective, we propose to examine the organoleptic and physico-chemical characteristics of such dairy products. By investigating these attributes, the study seeks to shed light on the implications of producing these combined cheeses for production costs, marketability, and potential profitability. This endeavor is situated within the broader strategic goal of enhancing Kazakhstan’s domestic food production industry, particularly focusing on dairy products, which are a staple in the Kazakh diet. The research is driven by dual imperatives: improving public health outcomes and stimulating economic growth. To gain empirical data and real market needs understanding, the authors conducted a poll of the residents of three major cities of Kazakhstan: the capital Astana, Almaty and Shymkent. The poll involved 1,000 residents of each of the named cities, which is approximately 0.5-1% of the population of such cities as of 2020. The poll was conducted over a one-month period among supermarket customers of different ages who choose dairy products – soft cheeses. Respondents were asked three questions, namely: In your opinion, is there a need in the Republic of Kazakhstan to produce a new dairy product, in particular soft cheese, with high vitamin content and low-fat content, based on organic fermented vegetables? What price would you be willing to pay for such a product? Should the new product be produced by national producers? The findings show that almost every resident of large cities of th","PeriodicalId":51923,"journal":{"name":"Economic Annals-XXI","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135827768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
