Назва: Application of robotics for automating livestock feeding and farm management Автори: Мартиненко, Володимир Олександрович; Martynenko, Volodymyr; Соколік, Віталій Дмитрович; Sokolik, Vitaliy; Плацканов, Владислав Володимирович; Plackanov, Vladislav Короткий огляд (реферат): The aim of the study was to evaluate the effectiveness of applying robotics for automating livestock feeding and farm management in Ukraine. The methodology was based on a comprehensive approach combining time recording, energy auditing, and economic analysis methods at four agricultural enterprises in the Kyiv, Cherkasy, Vinnytsia, and Poltava regions. Computer modelling (MATLAB Simulink), biosensor monitoring of animals, and advanced statistical methods (GPower, Shapiro-Wilk criterion) were used. The study found that the introduction of robotic feeding systems increased the accuracy of feed component dosing by 20.7%, feed mixing uniformity by 24.8%, reduced energy costs by 53.9%, and increased animal productivity by 12.3-13.7%. The economic feasibility is confirmed by an average payback period of 4.3 years with an internal rate of return of 27.5%, a return on investment of 34.7%, and a profitability index of 1.85. It has been determined that the most cost-effective solution is to introduce robotic systems on farms with a livestock population of 100 to 150 heads, where the use of suspended rail systems provides the best ratio of investment costs to economic benefit. The results of the study are of direct practical importance for the modernisation of livestock farms in Ukraine and can be used as a basis for the development of state programmes to support technological modernisation in the agricultural sector.

Назва: Scenario modeling of grain production potential in conditions of military risk: The case of Ukraine Автори: Zavadska, Yu.; Iatsenko, O.; Fiore, M.; Yatsenko, O.; Христенко, Ольга Андріївна; Khristenko, Olga Короткий огляд (реферат): This paper examines the transformation of Ukraine’s grain sector under the conditions of the full-scale war and its implications for global food security. Using annual data from 2000 to 2023, we forecast grain production potential for 2025–2026 carrying out ARIMA models (a non-seasonal specification within the SARIMA family). To support interpretation under heightened uncertainty, the results are discussed through three military-risk scenarios -low, medium, and high—that differ in the severity of constraints on agricultural operations and export logistics. The study finds that even under the high-risk scenario, Ukraine retains the capacity to supply over 5% of global grain exports. We argue that the key determinants of sector resilience include technological modernization, institutional support, and logistical adaptation. Additionally, an integrated scenario matrix is developed to link strategic priorities, implementation levers, and financing sources for grain-sector modernization. Four vectors for strengthening long-term resilience are identified: economic, technological, institutional, and European integration. The findings suggest that a coordinated, multi-vector strategy can help offset wartime losses and support Ukraine’s integration into the European market with higher value added and greater resistance to external shocks.

Назва: Emergency Household Water Treatment for Conflict-Induced Supply Disruption: A Case Study of Multi-Contaminant Raw Water in Mykolaiv, Ukraine Автори: Калініченко, Антоніна; Kalinichenko, Antonina; Ushchapivska, Tetiana; Honcharenko, Iryna; Гончаренко, Ірина Василівна; Hovorukha, Vira; Tashyrev, Oleksandr; Sporek, Monika; Patyka, Volodymyr Короткий огляд (реферат): Damage to urban water supply infrastructure can rapidly compromise access to safe water and force households to rely on alternative sources of uncertain quality. This study presents a case-based assessment of water quality and emergency household-level treatment options in Mykolaiv, Ukraine, following conflict-induced disruption of the centralized water supply system. Water samples collected from selected groundwater and distribution-network points were analyzed for physicochemical, organoleptic, and microbiological indicators, including total dissolved solids, hardness, sulfates, chlorides, iron, permanganate oxidizability, total microbial count, and E. coli. The results showed elevated mineralization, increased sulfate and chloride concentrations, high hardness, organic load indicators, and episodic microbiological contamination in several samples. A low-cost four-stage household treatment procedure combining chemical oxidation, thermal treatment, sorption, and short-term preservation was evaluated as a preliminary emergency approach. The procedure improved odor, taste, hardness, iron content, permanganate oxidizability, and microbiological safety; however, it did not fully reduce total dissolved solids, sulfates, or chlorides to drinking-water standards. Therefore, the treated water should be considered non-potable and suitable mainly for limited domestic and hygienic uses unless additional desalination or blending is applied. The study highlights both the potential and the limitations of simple household-level interventions under emergency water supply disruption and emphasizes the need for decentralized treatment support, monitoring, and long-term infrastructure recovery.

Назва: Monitoring successful cases of relocated enterprises and the contribution to regional development Автори: Христенко, Ольга Андріївна; Khristenko, Olga; Олійник, Тетяна Георгіївна; Oleynik, Tatyana; Табацкова, Ганна Вячеславівна; Tabatskova, Hanna Короткий огляд (реферат): The aim of this study was to analyse the socio-economic contribution of successfully relocated enterprises to the development of host regions in Ukraine and EU countries. The methodology was based on an applied study of cases of Ukrainian and European enterprises that changed the location of the operations. Relocation under wartime challenges ensured business survival and had a multiplier effect for communities. The company “Kulinichi” moved production from Kharkiv to Lviv region, invested EUR 20 million in a bakery complex, created more than 3,000 jobs (500 – for internally displaced persons); revenue increased from UAH 113.8 million in 2022 to UAH 214.3 million in 2024. The company “Akvaizol” moved from Kharkiv to Kalush, built a plant on an abandoned site, created 100 jobs; revenue in 2023 amounted to UAH 901 million, assets in 2024 – UAH 1.283 billion. The company “Chumak”, after losing its plant in Kakhovka, placed production in several regions and initiated the construction of a plant in Odesa region (potential for 5,000 jobs); revenue increased from UAH 573.3 million in 2022 to UAH 1.36 billion in 2024. The joint-stock company “Ukrai-nian Energy Machines” created branches in Lviv, Zakarpattia and Chernivtsi re-gions to reduce risks. In the EU, relocation was carried out for economic, logistical and regulatory reasons: the companies JPMorgan, Goldman Sachs, Citigroup, Bank of America and Morgan Stanley relocated part of the staff and assets to Frankfurt, Paris, Dublin, and Madrid to maintain access to the EU internal market. The company Bosch implemented a strategy of moving production closer to the consumer, expanding it in Hungary. The practical significance of the study lies in the use of the results to improve the policy of supporting relocated business and to develop indicators of its socio-economic impact.
