Glimpses of history of the Soviet light industry in Adygea: Maikop sewing factory

The relevance of the research is due to the rise of domestic industry and the tendency to restore light industry in the regions of the country. Despite the great scientific interest in the industry and fashion of the Soviet period, research on the history of the development, formation and functioning of light industry in Adygea has not been carried out, and therefore the chosen topic is very relevant. The problem of restoration and development of light industry, both in the country and in the region, solves a huge layer of economic and social problems of society, one of the main ones is the saturation of the domestic market with high-quality and affordable consumer goods. The goal of the research is a retrospective analysis of the activities of the Maikop sewing factory from the period of creation to the liquidation of the enterprise, based on significant periods of production. The research methods used are structural-functional, historical-genetic, chronological, retrospective, statistical, comparativetypological ones. The results of the research are the first published archival documents on the activities of the Maikop Sewing Factory, as well as the presented retrospective analysis of the factory activities, which makes it possible to assess the contribution of the Adygea sewing industry to the economic development of the region during the period of developed socialism, ensuring a steady increase in the well-being of the people, satisfying consumer demand.As a result of the research, the material on the history of the Maikop Sewing Factory, one of the cityforming enterprises of Adygea, has been systematized and introduced into scientific circulation. The industry began its development with a small hosiery cooperative “Rising Star”, which united various artisans and craftsmen. Over the next seventy years of its existence, the cooperative grew into a large industrial sewing enterprise, the production structure of which had a complete technological cycle. The factory included three branches, the total number of which was more than 2,000 employees. In the mid-1980s, the Maikop Sewing Factory was modernized with new foreign high-performance equipment, which allowed it to increase its industrial potential. The enterprise repeatedly emerged as the winner of socialist competitions at various levels, the factory teams annually participated in internal factory competitions, fulfilling the production plan by 130-140% and always calling on a related team to participate in the socialist competition. The Maikop Sewing Factory had its own brand store, a medical center, two kindergartens and a hostel. This article is a tribute to all the factory employees, and, of course, to the production directors, who throughout the Soviet period of the enterprise’s exis tence served as the very bonds for the entire team: Petr Vasilyevich Petrovsky, Ivan Sergeevich Paliy, Leonid Vasilyevich Fetisov and Lyudmila Kuzminichna Tchaikovskaya.

Sultanate Oman: a New Stage in the Development of Bilateral Trade with China

The article analyzes the dynamics and structure of bilateral trade between China and the countries of the League of Arab States (LAS), primarily with the Sultanate of Oman. It has been established that there is an increase in the trade turnover between China and its partner, while the balance is often not in favor of China due to the almost exclusive import of Arab hydrocarbons from China and exports of traditional products of machinery and light industry. At this stage, China has become the largest foreign trade partner of the Arab countries, displacing Western states in this area. The relevance, as well as the scientific and practical significance of the study, is due to the need, firstly, for a deeper analysis of the bilateral trade between the People's Republic of China and the Sultanate of Oman and the partial use of this experience in the Russian economy, and, secondly, to study the specifics of the development of the national economy and trade of the Sultanate of Oman, which is an urgent need from the perspective of, increasing its share in the extractive, industrial and financial sectors. The study was conducted on the basis of statistical and analytical materials and expert assessments of international institutions (UNCTAD, UN, OECD, WTO, IMF, World Bank) and organizations (OPEC, Arab Monetary Fund, Arab League, SAM, GCC, Arab Fund for Economic and Social Development), research institutes of China, the results of the author's own research. In conclusion, the author comes to the conclusion that it is important for Arab countries to form a long-term paradigm for the development of trade and economic relations with both China and other countries, and a conceptual model for its state regulation, taking into account not only current, but also the long-term interests of their own stable socio-economic development. In our opinion, the preferred option may be, for example, a unified (within the framework of the GCC) approach to solving these problems.

Features of information mathematical model in designing leather garments

The development of the leather industry in Kazakhstan is based on the annual production of hides of large and small livestock, and only 15% of hides of cattle in Kazakhstan are processed and further used for the manufacture of finished goods. According to official data, up to 40.6 thousand tons of wool are produced annually in the republic. However, a minuscule part of this volume is recycled. In modern research, the compilation of skin characteristics for the design of clothing is of particular interest. To achieve the goal of studying the features of the information mathematical model in the design of leather clothing related to the dynamics of the development of structural elements, specific interrelated tasks were solved through the formation of structural elements in clothing. Several constructive transformation options using graph theory are recommended. A mathematical model has been calculated for an optimal solution based on an impressive expert assessment of the structural elements of clothing, in the form of an information mathematical model described, which will simplify the formalization of the process of creating any clothing as a system that includes modular components to speed up the development of leather clothing, which is of interest in the design of leather clothing in the light industry.

Research on Overseas Market Demand Forecasting Model for Light Industry Products Based on Data Mining

Light industrial products have a significant share in international trade, and with the passage of time, the export volume of these products is also increasing year by year. From the revenue reports of Hikvision over the past 10 years, it can be seen that the sales of light industrial products, both domestically and internationally, are steadily increasing. Among the eight categories of light industrial products exported from China, five categories including tobacco and alcohol, textiles, cosmetics, gold and jewelry, and furniture show a positive growth in the number of exports. In the Vietnamese market, manufacturing and transportation are among the sectors that have the greatest impact on the growth of the Vietnamese economy. Surveys indicate that the volume of cargo transportation in Vietnam is increasing year by year, leading to a rising demand for transportation AGV robots. In the forecast model for cargo volume in the Vietnamese market, it is predicted that the volume of cargo transportation will gradually increase in the future, and therefore, the demand for pallet robots will also gradually increase with changes in cargo volume.

LICEDB: light industrial core enzyme database for industrial applications and AI enzyme design.

Enzymes, serving as eco-friendly catalysts, are progressively supplanting traditional chemical catalysts in light industry sectors such as feed, papermaking, textiles, detergents, leather, and sugar production. Despite this advancement, the variability in the performance of natural enzymes and the fragmentation and diversity of existing data formats pose significant challenges to researchers. Furthermore, AI-driven enzyme design is limited by the quality and quantity of available data. To address these issues, we introduce the light industrial core enzyme database (LICEDB), the first database dedicated exclusively to managing and standardizing enzymes for light industry applications. LICEDB, with its integrated modules for data retrieval, similarity analysis, and structural analysis, will enhance the efficient industrial application of enzymes and strengthen AI-driven predictive research, thereby advancing data sharing and utilization in the field of enzyme innovation.

The paper considers one of the important tasks of automated design of rational cutting schemes for rectangular materials on leather goods parts, namely the task of interactive correction of automatically designed rational cutting schemes for rectangular materials on leather goods parts. To successfully solve this task, the technological and mathematical formulation of this task is given. In the task of interactive design of cutting schemes for rolled materials for leather goods parts, the following main structural components for the mathematical model were identified and an analytical description of each of these components is presented: analytical representation of the material configuration; analytical representation of information about the external contours of the parts being placed; parameters that determine the location of parts on the plane; analytical description of conditions that prevent the intersection of parts with the edges of the material; the ability to identify each part on the material; ensuring mutual non-intersection of the active part with parts that are already in the cutting scheme; analytical formulation of the objective function. For the description of structural components: - the ability to identify each part on the material; - to ensure mutual non-intersection of the active part with the parts that are already in the cutting scheme, the method of angles was used, which allows to uniquely identify the mutual placement of the point and the polygon (the active point is inside the polygon or outside it). Using the analytical description of the selected structural components, algorithms for implementing this task were proposed in a software product for interactive correction of rational cutting schemes designed in automatic mode for rectangular materials into leather goods parts. The developed software product has a friendly interface and does not require additional knowledge of computer science when working with it. This product can be useful in preparatory and cutting production in light industry.

FORMATION OF THE PROFESSIONAL COMPETENCE OF FUTURE FASHION INDUSTRY SPECIALISTS WITH EMPLOYERS' INVOLVEMENT IN THE EDUCATIONAL PROCESS

The modern labour market in the fashion industry requires specialists with creative thinking, strong communication skills, initiative, and with the ability for continuous self-education, and quick adaptation to the demands of modern production environments. These specialists must possess high professional competence and practical skills for working in the real production sector. To form such specialists, it is increasingly relevant to consider the issues regarding the interaction between higher professional education systems and potential employers, as well as the exploration of innovative forms of integration and mutual interest between universities and businesses. This research aims to explore methods of forming the professional competence of future fashion industry specialists, considering employers' experiences and their involvement in the educational process. To determine the impact of educational activities conducted in production environments on forming professional competence in future fashion industry specialists, principles of the systemic approach were used. Theoretical methods such as synthesis, analysis, and generalisation were employed,alongside empirical methods including observation, interviews, questionnaires, testing, and surveys. The research is devoted to solving the issues of forming professional competence in future specialists in the fashion industry and developing students’ interest in the future profession by involving experienced industry specialists in the educational process and using the technical base of enterprises. The authors proposed innovative models for forming professional competencies inhigher education students studying Speciality 182: Light Industry Technologies by conducting variouseducational events in the industrial environment. The authors share their practical experience in conducting educational activities for students of Speciality 182: Light Industry Technologies at fashion industry enterprises and the methods of organising classes in the production environment of factories. They offer the following recommendations: each educational component's curriculum should establish a mandatory list of activities involving employers and specify the content of the classes. It is advisable to carry out classes at fashion industry enterprises, as a form of educational activity, purposefully and systematically. These activities should be at least 10-15% of the total study time, provided that partners characterising production processes will emphasise the professional growth prospects, and the profession's importance, additionally increasing students’ motivation. The use of active teaching methods in the educational process contributes to the formation and development of future fashion industry specialists' general and professional competencies and the development of independent thinking, creative activity, readiness for continuous education and self-education.

The characteristics of chronic benzene poisoning in 176 Chinese occupational population cases.

Benzene is a widespread environmental carcinogen known to induce leukemia. Chronic benzene poisoning is a significant occupational health issue in China, particularly among workers exposed to benzene. The aim of this study was to analyze the distribution patterns and trends of occupational benzene poisoning cases. This study included 176 cases who are diagnosed with occupational chronic benzene poisoning, via the Occupational Disease Direct Network Reporting System of the Sichuan Center for Disease Control and Prevention from 2005 to 2019. Data on gender, date of birth, years of benzene exposure, enterprise size, ownership type, industry were collected and descriptively analyzed. No significant differences were observed between males and females in terms of age or benzene exposure duration. The variation in gender distribution across 4 periods highlighted significant differences (χ 2 = 13.06, p = 0.004). Linear regression analysis indicated that the number of workers increased with year as the independent variable (r2 = 0.40, p = 0.016). The working duration of benzene exposure appeared to decline, but this trend was not statistically significant. The majority of employees were in medium and large-sized enterprises. Before 2016, workers were mainly in joint-stock enterprises and equipment manufacturing industries; however, from 2017 to 2019, benzene poisoning cases were increasingly found in private and light industries. Overall, this study may provide data resources for risk assessment among occupational benzene-exposed workers; therefore, the monitoring of benzene concentrations in the workplace should be strengthened, and targeted preventive measures for workers must be effectively implemented to protect their health.

Unleashing the Export Potential of Light Engineering Products: Evidence from a Firm-Level Survey

Based on a firm-level survey, this article analyzes the export potential, capacity, and challenges of the light engineering industries (LEI) in Bangladesh. The light engineering sector accounts for 2.5% of the country’s GDP and employs over 10 million people. Many of the firms operating in this industry are small-scale and decentralized, which makes them more accessible to local communities and helps in the promotion of inclusive growth. The industry's products are affordable and customized to meet the needs of local consumers, making them an essential component of the country's development strategy. However, there is a lack of credible information regarding the location of the light engineering enterprises and their export potential. The contribution of this paper is to fill this critical gap. The paper finds that the LE firms' location and specialization depend on the availability of raw materials and local demand; the firms operate with a small number of workers (less than 10) and mostly use domestic raw materials and conventional machines. However, they rarely replace their machinery, which affects productivity. Major findings also include that light engineering firms mostly produce agricultural machinery, spare parts, and machinery and parts for the construction sector, transport, textile, food processing, and molding industries. Meanwhile, the paper finds that less than 2% of the firms are currently exporting due to limited production capacity, lack of quality raw materials, insufficient capital, unskilled workers, and lack of policy support. Around 16% of the surveyed firms believe they have high export potential, whereas 82.4% of firms have no plans regarding exporting their products to the global market. To promote the industry's export competitiveness and overcome ongoing challenges, a set of policy recommendations are given, including effective policy implementation, utilization of firm-level dataset, product quality improvement, skills development, use of modern technologies, and adequate policy support from the government.

Facilitating or Inhibiting: Digital Transformation and Carbon Emissions of Manufacturing Enterprises

As global attention to the issue of climate change grows, the concepts of carbon peaking and carbon neutrality, proposed by China, have increasingly gained traction. In this international context, digital technology and green development are closely interwoven, carving out a distinct path for countries worldwide to achieve carbon emission reduction goals. This study empirically explores the mechanism of how digital transformation impacted the carbon emissions of Chinese A-share listed manufacturing enterprises from 2007 to 2021. The results indicate a significant inverted U-shaped nonlinear connection between digital transformation and carbon emissions within manufacturing enterprises. Green technology innovation, which is among the crucial driving forces for sustainable development, can act as a mediating factor. External environmental regulations positively moderate the relationship between digital transformation and carbon emissions in manufacturing firms. Furthermore, the heterogeneity analysis reveals that the nonlinear impact of digital transformation on carbon emissions in manufacturing enterprises is particularly significant in western regions, non-resource-based cities, light industry sectors, and large-scale enterprises. This paper innovatively verifies, at the micro level, the inverted U-shaped impact of digital transformation on carbon emissions in manufacturing enterprises, as well as its underlying mechanism. It provides theoretical support and practical guidance for the effective implementation of carbon emission reduction in the manufacturing sector. Meanwhile, it also offers valuable insights for manufacturing enterprises to formulate strategies that take both digital development and sustainable development into account, thereby contributing to the achievement of sustainable development.

Influence of Ownership Structure on the Innovation Activity of South Asian Companies at Different Life Cycle Stages

The lack of understanding management of corporate and financial innovation management in South Asia raises the fear of the declining effects of new technologies. Therefore, it is of practical interest to compare the estimates of the impact of ownership concentration in different innovation-intensive industries to minimize the agency problem among managers and shareholders. The paper provides an econometric analysis using panel regression of model testing on companies from technologically sophisticated industries, such as the Heavy and Light Industry, Information Technology (IT), and Consumer Staples from South Asia in different life cycles stages from 2015 to 2020. The South Asian market is volatile and receptive to innovations, but R&D capacity in some countries remains low. The paper provides a better understanding of the relationship between the concentration of different forms of ownership and the intensity of innovation, using industryspecifics and life cycle stages. It’s known that institutional investors are still interested in developing new digital marketing channels by competing with industry “disruptors” due to the lack of necessary strength in the IT industry along with barriers to cross-border investment. The paper confirms a linear and inverted U-shaped relationship between different forms of ownership structure and innovation activity. The results allow focusing on industrial and cultural differences to avoid agency and resource conflicts for majority shareholders of the company to build effective corporate governance, achieving strategic goals and minimizing the risks of improper management decisions in R&D.
