Authors: Lee Min Ho , Xiao Limin , Rychen Jonathan , Rinaldi Mariano P. , Arifianto Muhammad Reza , Vigo Vera , Fernandez-Miranda Juan C.
Published: December 2024

OBJECTIVE

Despite its potential advantages, robotic surgery has yet to be applied to skull base procedures. Complex anatomy and restricted access have limited the development of robotic skull base surgery. The authors’ aim was to conduct a feasibility study of robotic surgery for posterior fossa skull base lesions.

METHODS

Six silicone-injected postmortem human heads were prepared for the robotic surgery. Because there was no drilling tool with the robot, specimens were dissected in advance using an endoscope and microscope. The following approaches were investigated: 1) supracerebellar-infratentorial; 2) retromastoid; and 3) posterior occipitocervical junction surgeries. For each approach specific anatomical landmarks were identified, and the surgical freedom (vertical distance angle between the tools) was measured.

RESULTS

In the case of the supracerebellar-infratentorial approach, the authors used 3 burrs with 1.5 cm of diameter: 1 paramedian and 2 laterally. The view of the pineal region was visualized, and sufficient surgical freedom of both tools was secured. The median vertical distance was 1.2 cm (range 1.1–1.8 cm), and the median angle between the tools was 105° (range 92°–110°). On the other hand, in the retromastoid approach, with a single burr 2.5 cm in diameter, the root exit zone of the facial nerve was barely visible, and a space for tools to access was not secured. The median vertical distance was 0.8 cm (range 0.6–1.0 cm), and the median angle between the tools was 10° (range 6°–12°). In the case of the posterior occipitocervical junction approach, the authors used the 3 tubular retractors, 1 in the middle and 2 laterally. Even though the space was narrow, the medulla and adjacent nerves could be identified, and a moderate level of surgical freedom could be obtained for tool mobilization. The median vertical distance was 1.6 cm (range 1.2–2.5 cm), and the median angle between the tools was 90° (range 88°–95°).

CONCLUSIONS

Although robotic surgery has yet to be applied to neurosurgery, it is expected to be helpful in posterior fossa skull base surgery if appropriate tools can be developed.

Published: December 2024

OBJECTIVE

This study aimed to introduce a novel artificial intelligence (AI)–based robotic system for autonomous planning of spinal posterior decompression and verify its accuracy through a cadaveric model.

METHODS

Seventeen vertebrae from 3 cadavers were included in the study. Three thoracic vertebrae (T9–11) and 3 lumbar vertebrae (L3–5) were selected from each cadaver. After obtaining CT data, the robotic system independently planned the laminectomy path based on AI algorithms before the surgical procedure and automatically performed the decompression during the procedure. A postoperative CT scan was performed, and the deviation of each cutting plane from the preoperative plan was quantitatively analyzed to evaluate the accuracy and safety of the cuts. The duration of laminectomy was also recorded.

RESULTS

A total of 285 cuts were made on thoracic and lumbar vertebrae. The average duration for unilateral longitudinal cutting was 16.38 ± 4.76 minutes, while for transverse cutting it was 4.44 ± 1.52 minutes. In terms of accuracy assessment, 3 levels were divided based on the distance between the actual cutting plane and the preplanned plane: 77 (84%) were grade A, 15 (16%) were grade B, and none were grade C. Regarding safety assessment, 74 (80%) were designated safe (grade A), with 18 (20%) classified as uncertain (grade B).

CONCLUSIONS

The results confirm the accuracy and preliminary safety of the robotic system for autonomous planning and cutting of spinal decompression.

OBJECTIVE

Robot-assisted (RA) technology is becoming more widely integrated and accepted in spine surgery. The authors sought to evaluate operative and patient-reported outcomes (PROs) in RA versus fluoroscopy-assisted (FA) pedicle screw placement during minimally invasive surgery (MIS) transforaminal lumbar interbody fusion (TLIF).

METHODS

The authors retrospectively studied elective patients who underwent single- or multilevel MIS TLIF for degenerative indication using FA versus RA pedicle screw placement. Patients were selected from September 2021 to May 2023 at a single institution with multiple surgeons whose practice consists of primarily MIS. Outcomes included fluoroscopy dosage per screw, operative time per screw, anesthesia time per screw, estimated blood loss (EBL), screw revision rate, inpatient surgical complications, and minimal clinically important difference (MCID) of Oswestry Disability Index (ODI) and numeric rating scale (NRS) scores at the 6- and 12-month follow-ups. Comparability of groups was analyzed by univariate analysis. Multivariable analysis modeling fluoroscopy time per screw was performed, adjusting for confounders.

RESULTS

One hundred eighty-three patients (n = 133 in the FA group vs 50 in the RA group) were included. Patients in the RA cohort were significantly younger than those in the FA group (mean age 63.8 ± 11.9 vs 59.8 ± 11.0 years, p = 0.037). A total of 932 pedicle screws were placed (mean 5.1, range 4–8 per patient). The RA cohort demonstrated significantly lower intraoperative fluoroscopy dosage per screw (4.9 ± 7.6 mGy per screw vs 20.3 ± 14.0 mGy per screw, p < 0.001), significantly longer anesthesia time per screw (49.1 ± 12.6 vs 43.6 ± 9.2, p = 0.009), and similar operative time per screw (33.3 vs 30.7 minutes, p = 0.125). The screw revision rate for symptomatic radiculopathy was zero in both groups. Revision surgery requiring screw removal or reposition was performed in 4 total cases (RA group: 1/50 for infection; FA group: 2/133 for infection, 1/133 for foraminotomy). Both groups demonstrated significant improvement in PROs at 6 and 12 months compared with preoperatively. Moreover, both groups achieved MCID at similar rates.

CONCLUSIONS

When implementing RA technology, one can expect similar perioperative outcomes as FA techniques in addition to significantly lower radiation exposure. Moreover, there is no statistically significant difference in postoperative PROs between RA and FA. Longer anesthesia times may also be encountered, as in this study, which is likely a result of more complex robotic setup and workflow.

Authors: Хина А. Г. , Лисичкин Г. В. , Крутяков Ю. А.
Published: December 2024

В обзоре обобщены результаты работ по экспериментальному изучению физиологических процессов, происходящих в организме высших растений при их взаимодействии с высокодисперсным серебром. Показано, что наночастицы серебра способны к интернализации корнями и листьями растений, а затем к перемещению по всему растительному организму по апопластному и симпластическому путям. Попадая в организм растения, наночастицы серебра вызывают каскад внутриклеточных реакций. В зависимости от условий воздействия наночастиц, они могут приводить как к усилению роста растений и активизации в них процессов специфической и неспецифической защиты, так и к негативным последствиям, таким как угнетение развития. Показаны ключевые факторы, определяющие направленность и интенсивность воздействия наночастиц серебра на высшие растения, такие как доза и путь поступления наночастиц, а также их физико-химические параметры, включая размер наночастиц и природу поверхностного стабилизатора. Рассмотрены перспективные направления дальнейших исследований.

Исследовали фракционный состав жирных кислот (ЖК) липидов, выявлены основные направления их участия в структурно-функциональных адаптациях у доминирующих и редко встречающихся видов высших сосудистых растений арктических тундр Западного Шпицбергена. Выявлены различия по величине и изменчивости состава ЖК по фракциям: для гликолипидов – от 25 до 76%, для фосфолипидов – 10–28%, для нейтральных липидов – 7–57%. Установлена взаимосвязь между жирнокислотным составом разных фракций липидов и показателем “активность вида” у растений разного географического происхождения и экологии. Основные направления адаптации, связанные с липидной составляющей у арктических растений, включают участие насыщенных и ненасыщенных ЖК в разных соотношениях в зависимости от эколого-географических особенностей видов. Отмечено разнообразие ЖК с очень длинной цепью во фракционном жирнокислотном составе липидов у всех арктических растений. Показано, что в обеих адаптивных стратегиях: “избегание” и “адаптация” активно участвует липидная составляющая, которая обеспечивает соответствующую функциональную активность вида и его представленность в арктических тундрах Западного Шпицбергена.

Published: December 2024

Кокколитофорида Emiliania huxleyi была выделена в клоновую культуру из планктона прибрежных вод Черного моря в феврале 2023 г. Штамм альговируса EhV-SS2, поражающий этот вид водорослей, изолирован из прибрежных вод в мае 2023 г. С помощью сканирующей электронной микроскопии показано, что вирусные частицы имели форму икосаэдра диаметром 124–174 нм. Выявлено наличие суперкапсида у данного штамма и определен его титр (2.5×105 вирионов/мл). Исследовано влияние альговируса на рост и эффективность работы ФС II (Fv/Fm) E. huxleyi при различном уровне биогенных элементов в среде. На протяжении латентного периода альговируса (0–101 ч) отмечено снижение отношения Fv/Fm водорослей относительно его значений в контроле. В интервале времени с 101 по 168 ч в культуре появились первые лизированные вирусом клетки, выявленные с помощью световой и сканирующей электронной микроскопии. В течение периода с 168 по 264 ч процесс лизиса усилился, а его скорость на полной среде f/2 была в пять раза выше, чем при дефиците азота или фосфора. Скорость лизиса клеток на морской воде, лишенной питательных элементов, была в два раза ниже, чем на полной среде. К концу эксперимента (через 264 ч) в инфицированной культуре наблюдались функционально активные клетки, как покрытые кокколитами, так и лишенные их. Доля последних на среде f/2 составила 95%, тогда как при дефиците азота и фосфора она была незначительной.

Изучено влияние состава сахаров и pH питательной среды на рост и развитие пыльцевых трубок у интрогрессивного гибрида ели европейской и сибирской (Picea abies (L.) Karst. × P. obovata Ledeb.) in vitro. Показана динамика роста пыльцевых трубок ели. Установлено, что относительно высокая скорость роста пыльцевых трубок во многом обуславливает особенности физиологии их развития. Описана картина быстрого синтеза целлюлозы в процессе гидратации пыльцевых зерен ели. Выявлены различия компонентного состава пыльцы и пыльцевых трубок. Содержание белков, аминокислот, РНК, ДНК, липидов и полисахаридов по градиенту длины пыльцевых трубок у ели возрастали скачкообразно по направлению к растущему кончику и стабилизировались по достижении примерно половины их максимальной длины. При этом общее содержание углеводов в пыльцевых трубках по градиенту длины практически не изменялось. Описаны процессы формирования на поверхности пыльцевых трубок внешних колец, состоящих в основном из целлюлозы и каллозы. Высказано предположение, что такие кольца могут участвовать в регулировании тургора и в частичной компартментализации протопласта в пыльцевых трубках ели. Каллозу в пыльцевых трубках у ели следует рассматривать как ситуативный антистрессовый полисахарид, который не является постоянным компонентом стенки трубки.
Scopeloberyx shakhovskoyi, a new species of Melamphaidae family from the Atlantic Ocean
Authors: Kotlyar A. N.
Published: December 2024

A new species of family Melamphaidae is described from the central section of the Atlantic: Scopeloberyx shakhovskoyi. The species belongs to the oligorakered Scopeloberyx fishes (15–18 rakers on the first gill arch and pectoventral horizontal distance between the vertical lines of lower edge of the pectoral fin and the origin of pelvic fin is less than 5% SL). The fish were caught at depths in a range of 700–0 m. Scopeloberyx nigrescens sensu Keene is proposed as synonymous to the new species.

Published: December 2024

Environmental and ecological effects of the dam of the high-pressure Bratsk Hydroelectric Power Station (HPS) on the fish population and the probability of fish downstream migration from the Bratsk Reservoir have been studied. It has been revealed that thermal stratification of the water column is a significant factor in the ecological differentiation of the fish population in the upper reaches of high-pressure hydroelectric plants. According to hydroacoustics data, most of the ichthyomass, consisting of "warm-water" representatives of the Percidae (65%) and Cyprinidae (22%) families, is concentrated in the relatively warm layer of the epilimnion. Juvenile fish from 30 to 50 mm in size (up to 70% of the total fish number in this layer) are also concentrated here. In the cold-water hypolimnion, the fish population is represented by large single individuals of whitefish (Coregoninae). The data on distribution of fish in the lower and upper reaches of the dam, fish nutrition patterns, growth rate, and the presence of injuries that occur when fish pass downstream through hydroelectric plant dams are presented. Revealed differences in the growth rate of perches from the upper and lower reaches are associated with their constant inhabiting of water masses with contrasting temperatures. Net catches in the lower reaches over the four seasons of research lack injured individuals. These facts prove the absence of mass downstream passage of fish through the Bratsk HPS dam. Juveniles of cyprinids and perches accumulate in the upper warm layer of 0–10 m, i.e. outside the zone of the intake flow formation, which makes their entrance to intake openings at a depth of more than 20 m hardly possible.
Effect of illumination on the movement of rainbow trout Oncorhynchus (Parasalmo) mykiss (Salmonidae) juveniles in water flow and the level of thyroid hormones and cortisol in their blood

Published: December 2024

Long-term influence (53 days) of long-term constant illumination (100 and 1000 lux illuminance) on the behavior of rainbow trout Oncorhynchus (Parasalmo) mykiss juveniles and the level of thyroid hormones and cortisol in their blood has been experimentally recorded. At 100 lux illuminance, the fish moved equally upstream and downstream; i.e., their behavior was to stay in the current habitat. At 1000 lux illuminance, the fish more often moved upstream; i.e., their behavior was to leave the current habitat. The experimental illumination regimes did not affect the thyroid hormones and cortisol levels in the fish blood.

Published: December 2024

Scientific monitoring of pelagic fish stocks in 2004–2005 and 2014–2017 provided information on characteristics of sexual maturation of Atlantic chub mackerel Scomber colias in the coastal waters of the Central-Eastern Atlantic. Based on these results we describe ecological and geographical variability of some biological characteristics of the species. Features of sexual maturation of females and males of the mackerel can be described by a logistic equation obtained in the R programming environment. Fork length, at which 50% of individuals aged 1+ are mature, is 18.4 cm for females and 20.0 cm for males; 100% of individuals are mature at age 3+ with a fork length of 32.3 and 30.8 cm for females and males, respectively. A high proportion of spawning chub mackerel individuals in the Central-Eastern Atlantic have been recorded from February to March and from June to July. Chub mackerel in the coastal waters of this region are similar in life cycle characteristics to the populations of the waters off the Canary Islands and the Madeira Archipelago, but differ from the populations of the waters off mainland Portugal, the Azores, South Africa, and the Bay of Biscay in faster sexual maturation and growth rates.

Published: December 2024

The effectiveness of the food chemosensory attractants for attraction and angling of wild common carp, Cyprinus carpio by the bottom tackle of two types (carp “boil” device and “makushanka” device) was evaluated in the experiments, done in 2018 in the natural water reserve—the Akhtuba River (polygon of 80x30 m). There were 6 types of the bait used: sunflower meal, and boils with flavor of “Strawberry,” “Plum,” “Tutti-frutti,” “Sweet corn” and “Mussel.” The wild common carp was attracted to the polygon by inserting into the river the attracting groundbait, combined from sunflower meal cake, corn and wheat kernels and red clay (ratio 1:1:1:5). In 2–3 days after beginning of the attraction, the number of carp and its daily catch increased sharply and in a week reached the level which stay stable up to the end of experiment, that lasted for 79 days, from June, 19 through September, 5. Total catch was 1048 fish of body weight from 2 to 14 kg, average daily catch was 7.23±2.13 specimens. The catch on the makushanka was stable during the whole time of the experiment and was about 13–15% of the total catch, while the catch on the boils of the different flavors vary. At the beginning of the experiment the most of carps were catched on the boils having “Mussel” flavor. Then the catch on this boil type decreased to the middle of July, but the catch on the boil having “Sweet corn” flavor tended to increase up to 70–75% of the total catch on the boils of all types. The maximal catch on the boils with “Sweet corn” flavor correlated with the appearance of many anglers on the river, who used kernel for fish attraction. The catch on the boils of fruit and berry flavor vary, but stay relatively low, the minor catch was on the boils of “Strawberry” flavor. There was no plausible difference in the fish body weight, landed on different baits. The obtained data support the results of other studies showing important role of chemoreception in common carp behavior. We suppose that attraction of the wild common carp to the study polygon was due to the substances released by groundbait and accepted through the olfactory system, while the catch on the particular bait was a function of its smell, taste and textural features. It was found out that effectiveness of the food attractants can change during relatively short timeline (summer season), thereafter indicates the plasticity of the fish preferences mediated by chemosensory systems.

The article considers the determination of the optimal structural and technological parameters of injection molding, which are necessary to simulate the process of filling the mold cavity with a viscous liquid, which involves the construction of a numerical model of the flow of a viscous liquid in the mold cavity. The simulated process of the movement of a viscous liquid in the mold cavity using the finite element method. The implementation of the finite element method in the presented form leads to a symmetrical system of linear algebraic equations relative to the unknown nodal values of the velocity and pressure vector components. The use of the Moldex3D software complex made it possible to visualize the process of filling the cavity of the mold during the manufacture of the sole. The complex includes tools that provide automatic discretization of the initial area into triangular elements, formation of the matrix of finite elements taking into account the boundary conditions and solving the system of linear equations. By varying the location of the inlets and their diameters (that is, the initial values of the melt velocities in each inlet), it is possible to achieve the optimal location of the joining lines (places where the polymer solution flows are welded). Thus, simulating the process of filling the mold cavity with PVC material through the four inlet holes, it is possible to observe the process of formation of joints.
The proposed mathematical model of the flow of a viscous liquid in the cavity of the mold and the method of its implementation using the Moldex3D software complex will allow determining the optimal design of the molds and the technological modes of the process of filling them with polymer material.

Published: December 2024

Стаття присвячена вивченню питань, що пов’язані з забезпеченням бізнес-процесів виробництва продукції ресурсами та управління цим процесом. Функціонування будь-якого підприємства та його розвиток забезпечується ресурсами – перш за все, їх наявністю та вмінням їх раціонально використовувати. Розглянуто поняття ресурсного забезпечення виробничих та бізнес-процесів підприємств, що є основним для успішної діяльності будь-якого підприємства. Узагальнено погляди науковців щодо поняття «ресурсного забезпечення». Визначено, що для ефективного функціонування бізнес-процесів та підвищення конкурентоспроможності підприємства повинна бути сформована система управління ресурсним забезпеченням діяльності підприємства. Визначені та охарактеризовані основні види ресурсів та сформовано структуру системи ресурсного забезпечення виробництва продукції. Враховуючи, що молочне скотарство є однією із стратегічних галузей тваринництва в Україні та забезпечує продовольчу безпеку держави, розглянуто напрямки управління ресурсами при виробництві молока, адже структура системи ресурсного забезпечення для кожного бізнес-процесу є індивідуальною. Проаналізовано на основі статистичних спостережень динаміку виробництва молока за останні роки. Визначено важливість забезпечення ресурсами на всіх рівнях управління підприємством. Цифровізація бізнес-процесів забезпечує швидкий доступ до баз даних, дозволяє здійснювати контроль та оперативно приймати рішення щодо ефективного використання ресурсів. Основним завданням забезпечення конкурентоспроможності продукції є  зниження витрат на її виробництво. З допомогою цифровізації процесів вдасться оптимізувати надходження та витрати на всіх рівнях виробництва, адже зменшення ресурсоспоживання можливе лише при проведенні комплексної оцінки їх витрат та визначення шляхів раціонального  використання. Це допоможе підприємству обрати правильний напрямок формування ресурсів та їх використання, а також досягти конкурентних переваг на економічному ринку.

Стаття присвячена дослідженню дивідендних торгових стратегій як інструменту для зниження ризиків, пов'язаних з інфляцією, і збереження реальної вартості капіталу інвесторів. У роботі проаналізовано основні загрози інфляції для інвестиційного портфеля, що знижують купівельну спроможність і негативно впливають на дохідність традиційних пасивних стратегій, таких як індекс S&P 500. Висвітлено переваги дивідендних акцій як ефективної альтернативи для інвесторів, які прагнуть не тільки отримувати регулярні дивіденди, але й захищати свої активи від інфляційного впливу та інших ринкових ризиків.

Authors: Depri Hude , Fitriani Wahidah , Akbar M Ravi
Published: December 2024

AbstrakTujuan penelitian ini adalah menganalisis efektifitas media pembelajaran terhadap kreativitas siswa dalam proses pembelajaran Pendidikan Agama Islam (PAI) di sekolah menengah (SMA). Media dirancang pada setiap elemen pembelajaran PAI. Namun tidak semua media relevan dengan pembelajaran. Oleh karena itu, guru mesti melakukan analisis kebutuhan dalam memilih dan menggunakan media yang relevan. Meskipun media audio visual melalui cap cut, You Tube dan video animasi terlihat menarik, namun siswa sering tidak dapat menemukan fungsi media terhadap pembelajaran. Hal ini disebabkan karena belum terdapat penugasan yang ideal setelah menggunakan media. Bahkan media hanya sekedar pelengkap saja. Penelitian ini menggunakan metode kuantitatif komparatif dengan sasaran sampel sebanyak 100 siswa di SMAN 1 Lintau. Komparasi dilakukan terhadap media audiovisual yang dirancang pada setiap elemen PAI kelas X. Hasil penelitian menunjukkan bahwa efektifitas media terhadap kreatifitas siswa tertinggi pada media elemen SKI sebesar 45%. Sedangkan media pada elemen Al-Qur’an Hadis hanya meningkatkan 21% kreatifitas siswa. Kata kunci:  Kreativitas, Media Pembelajaran

Published: December 2024

Participatory approaches to innovation aim to address persistent failures of technology to respond to end-user needs and context. Here, we present the results of a transdisciplinary project aimed at co-developing new technologies for water quality monitoring in remote locations in developing countries. Drawing from critical social science, we developed and implemented a suite of approaches to engage community members and other regional stakeholders in an innovation process that is simultaneously social and technical. Part of our community engagement activities involved the sampling and molecular analysis of drinking water sources from two communities on the island of Efate in Vanuatu. The results revealed evidence for temporal variations in the extent of faecal contamination from different sources. This analysis was used to help frame discussions about microbial contamination, water quality and health, which, along with other structured conversations, led to technical and institutional specifications for water quality sensing. These co-developed specifications were striking, contradicting widely assumed requirements for handheld, rapid, mobile devices. Informed by these specifications, a device for monitoring colorimetric changes in response to microbial growth was designed and built. This device was able to quantify growth of faecal coliform indicator species Escherichia coli inoculated into sterile media. Subsequently, we showed the device could detect E. coli inoculated into sterilised river water. The limit of detection was as low as a single E. coli cell in 100 mL of liquid. Detection at this low concentration was achieved in 16 hours, meeting a specification requirement established through the co-design process.
Building Consensus in the Circular Economy: A Transdisciplinary Framework for Developing Collaborative Decision-Making Tools
Authors: Elnourani Mohamed , Rönnbäck Anna Öhrwall
Published: December 2024

The transition towards a circular economy requires an overarching perspective that recognises the dynamic and interdisciplinary nature of our current economic growth landscape. Circular economy inherently involves numerous stakeholders across the product life cycle. To establish efficient circular economy practices among these actors, this study suggests a novel framework for developing collaborative and interdisciplinary decision-making tools. By looking into relevant literature, organising a workshop, and analysing standard tools used in a circular economy like KPIs, risk analysis, Cost-Benefit Analysis, etc., we managed to capture the multidisciplinary challenges and dynamics faced by stakeholders of the circular business model. The contribution of this paper is the development of a framework that bridges requirement management techniques from product development practices with circular economy principles to facilitate effective decision-making processes. The framework effectively balances diverse stakeholder requirements, addressing uncertainties and multi-ownership challenges through product life cycles. This framework may be used to validate existing tools used by businesses and systematically develop new ones when needed. By facilitating collaboration around the circular economy, this framework not only reduces the environmental impact of economic growth but also encourages society to move towards more collective efforts to achieve sustainability. Finally, this article highlights the importance of a transdisciplinary approach in a systematic and effective transition to a circular economy.
Engineering Community Resilience: A Transdisciplinary Early Career Researcher’s Journey in Cultivating Bottom-Up Energy Initiatives Amidst Uncertainty
Authors: Djinlev Vanja
Published: December 2024

Navigating the evolving landscape of energy systems demands a multifaceted approach that combines engineering expertise with a holistic understanding of societal, economic, and environmental considerations. Early career researchers (ECRs) play a crucial role in bridging these disciplines, fostering innovation, and driving sustainable energy transitions. This paper delves into the unique intersection where an ECR in the engineering field transcends traditional technical boundaries, venturing into the realm of social sciences to foster energy communities. By employing a transdisciplinary approach, ECRs are not only contributing to the technical advancements in energy systems but are also actively engaging in community leadership and development, as tenets of energy communities. The role of engineers in this context is redefined – from mere providers of technological solutions to facilitators and catalysts of community-driven change. However, cultivating these initiatives is not without its challenges. The paper investigates the various forms of uncertainty that pose significant barriers to the development of bottom-up energy initiatives. These include regulatory ambiguities, market fluctuations, evolving technological landscapes, and financial constraints. Central to this paper is a case study from North Macedonia – the first energy community in the country, which provides concrete insights into the practical aspects of building and sustaining energy communities in a transitioning energy landscape. This case study not only illuminates the challenges faced but also showcases the strategies and approaches employed to overcome them. It serves as a microcosm of the broader global challenge in transitioning to more resilient, community-driven, and sustainable energy systems.
