Представлено результати досліджень просторової структури старовікових деревостанів на території природного заповідника «Горгани» та національного природного парку «Сколівські Бескиди» зі встановленням запасу вуглецю стовбурової деревини за вертикальними горизонтами. Дослідження просторової структури деревостанів природного походження є актуальними з погляду з’ясування можливостей адаптації лісів до зміни клімату, а також здатності лісових екосистем протидіяти абіотичним і біотичним збуренням.
Основними лісоутворювачами у старовікових деревостанах заповідних територій є аборигенні деревні види – бук лісовий, ялиця біла та ялина європейська. Диференціація дерев за ступенями товщини описується бімодальним розподілом. Спостережено високу мінливість за діаметром та висотою, що вказує на гетерогенність ознак обстежених насаджень. Розподіл запасу за висотними горизонтами нерівномірний: у верхньому ярусі зосереджено до 80% загального запасу та до 40% – загальної кількості дерев на 1 га. У старовікових деревостанах заповідної зони НПП «Сколівські Бескиди» за кількістю дерев домінує верхній ярус (до 60%), нижній ярус вміщає до 30%, середній ярус – до 20% дерев. У старовікових деревостанах ПЗ «Горгани» кількість дерев у верхньому та середньому ярусах є дуже подібною – тут зосереджено до 30% дерев, а у нижньому ярусі – до 40%. Для старовікових насаджень заповідних територій властивий групово-випадковий тип розміщення дерев. Щільність вуглецю стовбурової деревини у досліджуваних деревостанах є найвищою у першому ярусі і може змінюватися від 110 до 220 т/га.

Термопластичні плівки – один із перспективних видів клейових матеріалів для виготовлення нетоксичної фанери. У цій роботі запропоновано використання первинної термопластичної плівки поліетилену низької густини (ПЕНГ) для виготовлення фанери. Основним завданням дослідження було з’ясувати механічні властивості фанери, склеєної зі шпону різних порід деревини плівкою ПЕНГ різної товщини. Для кращого розуміння процесу склеювання листів лущеного шпону термопластичною плівкою було використано деревину різних порід – тополі, берези, граба та бука, а також різні товщини плівки – 50, 80, 100 і 150 мкм. Для порівняння виготовляли фанеру, склеєну карбамідоформальдегідним клеєм.
Результати дослідження продемонстрували, що зразки фанери з використанням шпону деревини усіх досліджуваних порід, склеєних плівкою ПЕНГ, володіють задовільними механічними властивостями: міцністю на зріз, міцністю на згин та модулем пружності. Встановлено, що така фанера, за значеннями міцності на зріз, має досить високі показники, які перевищують рекомендоване значення міцності 1,0 МПа згідно стандарту EN 314-2. З’ясовано, що порода деревини шпону більшою мірою впливає на механічні властивості фанери, тоді як товщина плівки ПЕНГ впливає меншою мірою. Фанера з тополевого шпону мала найнижчі значення міцності на згин та модуля пружності, крім міцності на зріз, яка була на тому ж рівні, що і для березової та грабової фанери. Зразки букової фанери мали найкращі механічні властивості.  
На загал, результати дослідження підтвердили доцільність заміни рідкого термореактивного карбамідоформальдегідного клею на термопластичну плівку ПЕНГ для виготовлення малотоксичної фанери, яку можна застосовувати у виробництві меблів (особливо – дитячих) та оформленні інтер’єру і екстер’єру.
Вплив кліматичних чинників на формування радіального приросту деревини горіха грецького
Authors: Osadсhuk Leonid , Mahuran Volodymyr , Kondratiuk Liubov
Published: December 2024

Кліматичні умови Правобережного Лісостепу України, зокрема кількість опадів і середньомісячні температури, впливають на ріст і розвиток горіха грецького, який є одним із характерних видів для цього регіону. Відзначено важливість вивчення впливу кліматичних чинників на ріст лісових насаджень та необхідність їх урахування під час вирощування горіха грецького у Правобережному Лісостепу.
Статистичний аналіз деревно-кільцевих хронологій свідчить про придатність їх для подальшого аналізу в зв’язку з тим, що встановлені серії мають міжсерійний коефіцієнт кореляції 0,59 для плантаційного насадження та 0,55 для лісового деревостану. Чутливість деревно-кільцевої хронології плантаційного насадження дещо перевищує середнє значення і становить 0,32, а для лісового насадження становить лише 0,17 і є нижчою, ніж середнє значення. Таким чином, горіх грецький при плантаційному вирощуванні є більш чутливим до варіабельності умов довкілля порівняно, з лісовими насадженнями, які є більш стійкішими впливу до негативних чинників.
Також за результатами аналізу значень радіального приросту, стандартного відхилення, коефіцієнтів варіації та чутливості деревно-кільцевих хронологій, виокремлено періоди росту і розвитку горіха грецького, які характеризувались певними особливостями формування радіального приросту.
Радіальний приріст горіха грецького при плантаційному вирощуванні показав достовірний зворотний зв’язок із опадами, проте опади не мали значного впливу на формування приросту за діаметром у дерев, які ростуть у лісових умовах. Різна реакція горіха грецького на кліматичні зміни в плантаційних насадженнях і лісових умовах дає змогу застосовувати відповідні технологічні заходи для нівелювання або послаблення прояву негативних стресових кліматичних проявів.
Кліматоформуюча роль продукційного процесу лісів України
Authors: Tretyak Platon , Lukianchuk Nelia , Krynytskyy Hryhoriy
Published: December 2024

Ліси України щорічно можуть депонувати понад 22 млн т вуглецю, продукувати понад 60 млн т кисню, транспірувати 36272 млн т водяної пари, споживаючи при цьому 24 млн ГВт∙год енергії. Цей матеріально-енергетичний баланс життєдіяльності лісів України є у 4 рази меншим, ніж лісів Німеччини і у 1,3 рази меншим, ніж лісів Польщі. Відповідні пропорції властиві також для здатності лісової рослинності охолоджувати повітряний басейн. В Україні цей показник становить 2,48ºС в межах вкритих лісом земель. У межах всієї території України таке охолодження може становити 0,39ºС, що є удвічі більшим показником, ніж відповідне значення для всієї території Центральної та Східної Європи.
Частка такого продукційного процесу лісів у межах Волинської, Рівненської та Житомирської областей Поліського регіону може становити 24% відповідних показників в Україні загалом, а лісів у межах  Львівської, Тернопільської, Хмельницької, Івано-Франківської та Чернівецької областей, що у Лісостеповій зоні, може становити 23%. В межах обраних модельних областей України потенціал продуктивності та показники матеріально-енергетичного балансу лісів можуть бути рівним або у 2-3 рази більшими, ніж у лісах України, а також від двох до шести разів більшим, ніж у лісах Центральної та Східної Європи загалом. Цей аспект має важливе локальне кліматоформуюче значення, оскільки призводить до збагачення повітря киснем і водяною парою та його охолодження.
Для підвищення матеріально-енергетичних показників життєдіяльності лісової рослинності потрібно зосередити увагу на необхідності збільшення площі лісів та їх продуктивності. Бажано вирощувати деревостани, що відзначаються високими показниками щорічного приросту стовбурової деревини. Цього можна досягнути збільшенням представництва у лісостанах швидкорослих деревних видів, що призведе до збільшення питомих сум площ перерізу стовбурів дерев та загальних запасів деревостанів, а також показників їхнього щорічного приросту.

Authors: Antipov I. , Vasylenko T.
Published: December 2024

Context. The mass spread of Wi-Fi networks is facilitated by the simplicity of their deployment, high speed, universality, and convenience of use. The development and dissemination of these networks continue despite a number of shortcomings. One of the shortcomings is their vulnerability to various types of attacks, including those based on the forgery (imitation) of identification data. At the same time, there are physical layer characteristics, knowledge of which expands the understanding of the network’s state, can contribute to increasing the reliability of network subscriber identification, and thus prevent a number of attacks. This research is aimed at the theoretical and practical substantiation of the possibility of their application.
Objective. The aim of the study is to assess the application of detailed analysis of signal spectra emitted by devices connected to wireless Wi-Fi networks for their identification. To achieve this goal, it is necessary to analyze the experimentally measured spectra of wireless devices connected to the Wi-Fi network and evaluate the possibility of using the spectrum for the identification of mobile devices.
Method. This work proposes a method for processing the results of measuring the spectra of Wi-Fi device emissions by evaluating the asymmetry coefficient of the Wi-Fi device spectrum’s cross-correlation function. Mathematical modeling was used to assess the effectiveness of the method.
Results. The research results show that the minimum value of the asymmetry coefficient when comparing the template with different positions of one’s own device, and large values of the asymmetry coefficient when comparing templates with foreign spectra. Therefore, this characteristic can also be used for the identification of Wi-Fi devices.
Conclusions. The research results suggest the possibility of applying the proposed method for the identification of mobile devices, which will qualitatively complement existing security models with another feature for detecting unauthorized access.
MODELING OF THE SPREAD OF TUBERCULOSIS BY REGIONS IN UKRAINE
Authors: Boyko N. I. , Rabotiahov D. S.
Published: December 2024

Context. Modelling the spread of tuberculosis in Ukraine is particularly relevant due to the increasing number of cases, especially in 2023.
Objective. The aim of this study is to solve modeling tasks by applying modern machine learning methods and data analysis to build predictive models of tuberculosis spread at the regional level.
Method. To model the spread of tuberculosis at the regional level in Ukraine, it is proposed to use several approaches, such as the SIR model, cellular automata, and Random Forest. Each of these methods has its unique advantages and can provide a more detailed understanding of the dynamics of disease spread. The SIR model (Susceptible-Infectious-Recovered) is a classical epidemiological model that describes the spread of infectious diseases in a population. The model assumes three groups of the population: S (Susceptible) – susceptible to infection; I (Infectious) – infected and capable of transmitting the infection; R (Recovered) – those who have recovered and gained immunity. Cellular automata are a discrete model that uses a grid of cells to simulate spatiotemporal processes. Each cell can be in different states (e.g., healthy, infected, immune) and change its state depending on the states of neighboring cells. Random Forest is a machine learning method that uses an ensemble of decision trees for classification or regression. This method can be applied to predict the spread of tuberculosis based on a large number of input parameters. Using these methods will allow for a deep analysis and comprehensive results regarding the spread of tuberculosis at the regional level in Ukraine. This, in turn, will facilitate the development of effective strategies to combat the disease and improve public health..
Results. The results of applying the Random Forest and SIR methods were described and analyzed in detail. For Random Forest, the metrics MSE and R2 were evaluated, showing high prediction accuracy. In the case of the SIR algorithm, visual assessment of the results revealed insufficient accuracy due to model limitations. Comparing the chosen methods with other studies, a conclusion was made about the need to consider more complex algorithms to obtain more accurate results.
Conclusions. Based on the research results, it can be concluded that the Random Forest method is sufficiently effective for predicting vulnerable social groups and that the SIR algorithm is less effective for modeling the spread of tuberculosis. For further research development, it is recommended to consider more complex algorithms and account for additional factors influencing the spread of the disease. Moreover, to better understand further actions to combat the disease, it is advisable to simulate the spread of tuberculosis among the population of Ukraine.

Authors: Bodyanskiy Ye. V. , Savenkov D. V.
Published: December 2024

Context. This paper provides a new approach in concept drift detection using an ensemble of simple spiking neural networks. Such approach utilizes an event-based nature and built-in ability to learn spatio-temporal patterns of spiking neurons, while ensemble provides additional robustness and scalability. This can help solve an active problem of limited time and processing resources in tasks of online machine learning, especially in very strict environments like IoT which also benefit in other ways from the use of spiking computations.
Objective. The aim of the work is the creation of an ensemble of simple spiking neural networks to act as a concept drift detector in the tasks of online data stream mining.
Method. The proposed approach is primary based on the accumulative nature of spiking neural networks, especially Leaky Integrate-and-Fire neurons can be viewed as gated memory units, where membrane time constant Гm is a balance constant between remembering and forgetting information. A training algorithm is implemented that utilizes a shallow two-layer SNN, which takes features and labels of the data as an input layer and the second layer consists of a single neuron. This neuron’s activation implies that an abrupt drift has occurred. In addition to that, such model is used as a base model within the ensemble to improve robustness, accuracy and scalability.
Results. An ensemble of shallow two-layer SNNs was implemented and trained to detect abrupt concept drift in the SEA data stream. The ensemble managed to improve accuracy significantly compared to a base model and achieved competitive results to modern state-of-the-art models.
Conclusions. Results showcased the viability of the proposed solution, which not only provides a cheap and competitive solution for resource-restricted environments, but also open doors for further research of SNN’s ability to learn spatio-temporal patters in the data streams and other fields.

Geride kalan yüzyılın son çeyreği ile birlikte yeryüzünün evrimini şekillendiren en önemli değişim adımlarından biri olan küreselleşme, insanlık adına dünyayı daha iyi bilinir, takip edilebilir ve farklı açılardan karşılaştırılabilir bir noktaya taşımıştır. Daha hızlı ve kolay erişim ile etkileşim üzerine inşa olunan bu yakınsama, kapsam sürekli genişleyen yoğun bir rekabeti de beraberinde getirmiştir. Bugün gelinen noktada, rekabette avantajı ve maddi-manevi farklı odakları olabilen karlılığı sağlayacak çabaların asıl kaynaklarından biri de benzerler arasında fark edilmek ve tercih edilmeyi sağlayacak bir fark yaratmaktır. Fark edilme ve fark yaratma çabasının günümüzdeki en somut adımlarından biri, sunulan mal ve/veya hizmetleri belirli bir kalite düzeyine çıkarmak ve söz konusu kalitenin sürekliliğini güvence altına almaktır. Sistematik ve çok fonksiyonlu bir işleyişi gerektiren bu süreç tanınmak, onaylanmak ve yetkin kabul edilmek anlamına gelecektir ve bugün hemen tüm kurum ve kuruluşların asli çabasıdır. Bu çalışmada, tüm dünyada olduğu gibi Türkiye’de de fark edilme ve fark yaratma açısından yükseköğretim kurumlarının gündeminde daha çok yer almaya başlayan kaliteli hizmet bağlamında akreditasyon süreci ve bu süreçte üniversite kütüphanelerinin rolünün ortaya konulması amaçlanmıştır. Yükseköğretim kurumlarının akreditasyon sürecine kütüphanelerin penceresinden kavramsal temelli bir bakışın kurgulandığı çalışmada, betimleme yönteminden yararlanılmıştır. Çalışmanın kapsamını, kalite ve akreditasyon kavramları ile süreçlerinin yükseköğretim kurumlarının kütüphaneleri ile kesişen yanları ile bu yanların sürece katkısının kavramsal boyutu oluşturmaktadır. Kalite ve akreditasyon süreçlerinin yükseköğretim kurumlarındaki yeri ve önemini kütüphane ile olan ilişkisi üzerinden serimlemeyi hedefleyen çalışma, bu yönüyle ulusal literatürde benzerlerinden ayrılmaktadır. Kalite ve akreditasyon süreçlerinin yakın gelecekte Türkiye’deki yükseköğretim kurumlarının öncelikli gündemi içinde yer almaya devam edeceği öngörüsü ile bakıldığında, çalışmanın hem üniversite kütüphanelerin akredite sürecindeki yeri ve öneminin daha belirgin görülmesini, hem de bu kütüphanelerin sürece katkısının derinliğinin sorgulanmasını sağlayacağı değerlendirilmektedir.
КІНЕТИКА ВИЛУЧЕННЯ ОЛІЇ З МАКУХИ СОНЯШНИКУ В УМОВАХ АДРЕСНОЇ ДОСТАВКИ ЕНЕРГІЇ

Published: December 2024

У даній статті розглядаються результати досліджень кінетики вилучення олії з макухи соняшнику. Відомо, що після пресування в капілярних структурах макухи залишається олія. З метою більш ефективної переробки сировини, залишки олії екстрагують органічними розчинниками.
З метою підвищення якості та екологічної безпеки, неполярні екстрагенти, такі як гексан або екстракційні бензини, які є продуктами переробки нафти, поступово замінюють відновлюваним і менш токсичним етанолом.
Проте існує проблема невисокої розчинності тригліцеридів жирних кислот в етанолі. Ефективність етанолу в якості екстрагента пов’язується з емульгуванням олій, а не тільки розчиненням.
У статті пропонується інтенсифікувати як масообмінну складову процесу вилучення олії (екстрагування), так і гідромеханічну (емульгування) за допомогою технологій адресної доставки енергії.
Робиться припущення, що механізм механодифузії в умовах дії мікрохвильового поля не тільки руйнує капіляри сировини та інтенсифікує дифузійні процеси, а й збільшує вихід дрібнодисперсних крапель олії в екстрагент.
Проведено експериментальні дослідження залежності кінетики екстрагування олії від температури, гідравлічного режиму, розміру частинок, питомого підведення енергії. Здійснено спроби гідромеханічного відокремлення олії від емульгованого екстракту.
Встановлено, що адресна доставка енергії та подрібнення макухи збільшують вихід олії. Збільшення питомих енерговитрат у досліджуваному діапазоні не впливає на вихід олії, що відкриває можливості до зменшення цього показника та подальшого підвищення енергетичної ефективності процесу.

Partial resection as a treatment for mucoid degeneration of the anterior cruciate ligament: a case report
Authors: Amith Kumar Krishna , Narayan Ranjith
Published: December 2024

Mucoid degeneration of the anterior cruciate ligament (MDACL) is an uncommon degenerative disease. Objective. To present a case of mucoid degeneration of the anterior cruciate ligament diagnosed using Magnetic Resonance Imaging and treated with arthroscopic resection. Methods. In our case report, we examined the medical history of a patient and developed a list of clinical manifestations observed in our case. Magnetic Resonance Imaging is the most efficient approach for differentiating between mucoid degeneration of the anterior cruciate ligament and other knee joint disorders. Results. Our patient presented with a 3-month history of right knee discomfort. The age of the patient was 28 years old. There were no indications of edema or instability, although his knee flexion ranged from 0°–100°. We diagnosed MDACL using MRI and arthroscopic findings. In T2-weighted images, the ACL exhibited an abnormally elevated signal with a mass-like structure of its fibres. In T2-weighted coronal images, the association between the fibres and the aberrant soft tissue was discernible. Based on normal preoperative findings, this case was diagnosed and presented. Magnetic Resonance Imaging revealed a celery-stalk-like appearance of the anterior cruciate ligament suggesting mucoid degeneration of the anterior cruciate ligament, with additional joint effusion. Upon arthroscopy, the anterior cruciate ligament appeared homogenous and hypertrophied with a bulbous lateral portion. The yellow and sclerotic lesions on the lateral portion of the anterior cruciate ligament were excised precisely. Conclusions. In the present case, arthroscopic resection of a degenerating ACL that is causing pain demonstrated good results. In some cases it could lead to subjective progressive laxity after the surgery. The prognosis is dependent on the age of the patient and what other injuries they might have. MDACL should be considered when there is unusual discomfort in the spine and limited flexing. MRI and arthroscopy both pointed to the same diagnosis.
Konflikt o piękną Helenę czy o szlaki handlowe? – aspekty gospodarcze jako potencjalna przyczyna wybuchu wojny trojańskiej
Authors:   Uniwersytet im. Adama Mickiewicza w Poznaniu, Sypniewska Nell
Published: December 2024

The article presents the causes of the mythical Trojan War. In the original Homeric account, commonly known in the laterform of the written version of the Iliad, the author states that the outbreak of the war was brought about by the kidnapping of Helen, the wife of the King of Sparta, by the Trojan prince Paris. According to later Greek sources, the causes of the conflict were a series of kidnappings of women and a related violation of the divine principle of hospitality, xenia. Today, the ancient concepts are being abandoned in favor of an explanation of an economic nature, establishing Troy at the center of the Anatolian trade routes. This hypothesis, formulated by archaeologists working at Troy, places it in the role of a center of trade between the Black and Aegean Seas as well as Anatolia and the Mediterranean area. The above-mentioned assumptions caused a lot of controversy, which resulted in a discussion in the scientific community. The aim of the article is to analyze the economic aspects of the Trojan War that resulted from this dispute, in the form of the presentation of the Anatolian Bronze Age trade routes.

The botanical characteristics, cultivation patterns, and economic importance of Piper nigrum are reviewed, alongside its extensive use in treating respiratory conditions, gastrointestinal disorders, and inflammation. The bioavailability-enhancing effects of piperine, which amplify the absorption of drugs and nutrients, are emphasized. Also, black pepper essential oil has many health benefits, such as protecting neurons, lowering blood sugar, and fighting cancer. These benefits are mostly due to compounds like β-caryophyllene, sabinene, and limonene. While the pharmacological potential of black pepper is well-recognized, this review highlights critical research gaps, including the need for standardized methodologies and robust clinical trials. By synthesizing data from multidisciplinary studies, this work provides a comprehensive outlook on the multifaceted applications of black pepper, laying a foundation for future innovations in health and industry.

Seaweed has been consumed for hundreds of years due to its biologically active properties, particularly its high antioxidant activity. It is low in fat and a good source of fiber and minerals, and is considered nearly a complete protein. The new product, in addition to the kelp powder content, is distinguished by the addition of Lactobacillus paracasei culture and spelt flour. This study highlights the development and characterization of a novel kelp powder-based bakery product. Three experimental variants (B1 - muffin with 5% kelp powder, B2 - muffin with 10% kelp powder, and B3 - muffin with 15% kelp powder) were comparatively analysed. The muffins were subjected to physicochemical, microbiological, and spectrophotometric analyses. The finished product was monitored over a period of 5 days, stored at room temperature. The acceptability of the new probiotic muffin assortment was evaluated with a sample of 137 participants, mostly consumers of bakery products. The results of the analyses showed that the muffins exhibited microbiological characteristics within the allowed limits for up to 3 days of storage at room temperature, after which an increase in the total number of yeasts and molds was observed. The new product is high in bioactive compounds but low in fat due to the addition of brown seaweed.

Published: December 2024

Although whey has long been considered a by-product of no major value, today it is recognized for its rich nutritional content and the ability to add diversity and benefits to the daily diet. Modern technologies and innovations in the field of whey processing allow turning it into a valuable product, providing nutritional benefits and a delicate taste that can be easily integrated into a variety of products. The objective of this research was to obtain an innovative product, a whey cheese with sensory properties and a high nutritional value by incorporating oregano essential oil (Origanum vulgare) in the cheese obtained, the analysis of the product and the evaluation of the preservation effect of oregano essential oil. Three types of whey cheese (’’urda’’cheese) were produced: the control ’’urda’’ cheese with no addition (UM); ’’urda’’ cheese with 0.01% addition of oregano essential oil (UO1); and ’’urda’’cheese with 0.02% addition of oregano essential oil (UO2). Analyses of the finished product concerned fats, acidity, E. coli, the number of yeasts and molds and coagulase-positive staphylococci. The sample with 0.02% oregano essential oil was found to be the most appreciated, followed by the control sample, which took second place, and finally, the sample with 0.01% oregano essential oil. The control sample recorded a greater increase of acidity relative to UO2, which is due to the antimicrobial activity of oregano essential oil. After determining the fat content and the total dry matter, lower values were determined in the sample with added essential oil (0.02%) compared to the control sample. For yeasts and molds, a much more moderate increase is observed in the sample with the addition of 0.02% essential oil.

Aim. To identify the most appropriate surgical treatment method for patients with colorectal cancer metastases to the liver by means of a comparative analysis of immediate and long-term outcomes of anatomical and parenchyma-sparing liver resections.

Materials and methods. A retrospective analysis was conducted on the surgical treatment outcomes of 87 patients with colorectal cancer metastases to the liver who underwent surgery between 2008 and 2023. The analysis involved the pseudorandomization method to eliminate the influence of unaccounted factors and improve the statistical validity of the study. Age, sex, body mass index, synchronous nature of metastasis, number of metastases, tumor burden, etc. were used as variables to calculate the probability factor.

Results. A total of 87 observations were analyzed. Using the pseudorandomization method, 18 pairs of patients who underwent anatomical resection and parenchyma-sparing surgery were formed. The volume of blood loss was significantly lower in the parenchyma-sparing resection group (Me 250 ml; 187–525 ml) compared to the anatomical resection group (Me 850 ml; 315–2325 ml; p = 0.001). The duration of hospital stay after parenchymal-sparing resections accounted for 12 days, while after anatomical resections, it comprised 18 days (p = 0.031). The incidence of postoperative complications revealed no significant difference (p = 0.348). Positive resection margins were more frequently found in patients who underwent parenchyma-sparing surgery (16.7% and 5.6%, p = 0.289). The difference in overall and disease-free survival was not statistically significant.

Conclusion. Parenchymal-sparing liver resection is found to be a safe alternative to anatomical resection, allowing for the maximum preservation of liver tissue while achieving adequate oncological outcomes.

Introdução: As relações entre os indivíduos são construídas, ao longo do ciclo vital, influenciam a funcionalidade da família, sendo relevantes para a unidade dos membros e função de qualquer família. Desta forma, a boa funcionalidade familiar (FF) promove a manutenção e integridade físico-psicológica dos membros da família, garantindo o bem-estar e estilos de vida promotores de saúde. Objetivo: Analisar a relação entre a FF e o grau de dependência à nicotina. Metodologia: Trata-se de um estudo descritivo-correlacional, transversal e de abordagem quantitativa, no qual participaram 364 utentes de uma Unidade de Saúde Familiar (USF), do norte de Portugal. Na recolha de dados utilizámos um questionário online, tendo os dados resultantes da sua aplicação sido tratados através do software SPSS 29.0, com recurso à estatística descritiva e inferencial. Resultados: Do total da amostra (n= 364) a maioria dos utentes respondentes, membros de uma família, era do sexo feminino (69,0%), pertencia ao grupo etário dos 34-44 anos (62,4%), detinha o estado civil de casado (63,7%) e possuía como habilitações literárias o Ensino superior (60,7%). A maioria da amostra percecionava a sua família com altamente funcional (76,4%), dos quais 21,2% eram consumidores de tabaco e o maior grupo destes utentes (n=77) foi classificado com um grau de dependência à nicotina Muito Baixo (36,4%). Não se verificaram diferenças estatísticas significativas entre a pontuação da FF e o grau de dependência à nicotina (Kruskal-Wallis: p ≥0,127). Conclusões: A maioria dos utentes perceciona ter uma família altamente funcional, sendo que a maioria da amostra foi classificada no grau Muito baixo e Baixo de dependência à nicotina. Não existe relação entre a perceção da FF e o grau de dependência à nicotina. No entanto existem algumas famílias com perceção de Disfunção severa que é necessário acompanhar e promover intervenções para a melhoria da FF.
