Hodgkin’s lymphoma (HL) is a malignancy of B-cell origin that mainly affects the tissue of the lymph nodes, spleen, disease and bone marrow. In majority of patients the diagnosis is made in the age between 15 and 30 years, followed by another peak at age ≥ 55 years. The cause is not known for certain, but there are various risk factors such as: genetic disease (family history); environmental associations (woodworking industry, etc.); history of phenytoin treatment, altered therapy, or chemotherapy. An important is a role of infection: Epstein-Barr virus (EBV), mycobacterium tuberculosis, herpesvirus type 6, and human immunodeficiency virus (HIV — human immunodeficiency virus). Immunosuppression (post-transplant patients who take immunosuppressants), congenital immunodeficiency disorders (Klinefelter syndrome, Chediak-Higashi syndrome, Wiskott-Aldrich syndrome), some autoimmune diseases (rheumatoid arthritis, celiac disease, Sjogren’s syndrome, systemic lupus erythematosus) increase the risk of the disease. The WHO (World Health Organization) classification divides LC into two main types: classic (which accounts for about 95% of cases) and nodular — with a predominance of lymphocytes (occurs in 5 % of patients). Typically diagnosis is not to complicated, when routine methods of examination are used. In 2022, approximately 8,540 LC cases were diagnosed in the United States, and 920 patients died from the disease. Primary lesions of the lungs are rare and account for 0.5 % of all primary lung neoplasms. Lung involvement usually indicates the stage IV of the disease. About 85-90% of patients with limited-stage classical Hodgkin lymphoma are treated, compared with 75–80 % of advanced-stage disease. Patients who do not achieve complete remission after treatment or who relapse within 12 months have a poor prognosis. Current report presents atypical clinical case of Hodgkin’s lymphoma causing difficulties in diagnosis. Conclusions. The initial manifestations of Hodgkin’s lymphoma as the primary lung disease is an extremely rare, therefore, in order to shorten the time from the moment the patient enters the clinic to the verification of the diagnosis, it is better to use mini-invasive diagnostic methods (videothoracoscopic biopsy of the mass, transthoracic needle biopsy), which allows obtaining a diagnosis and choose the safest and most optimal type of treatment. Key words: Hodgkin’s lymphoma, transthoracic needle biopsy of the lung, computed tomography, young age, lungs.

When and How to Deviate from a Preregistration
Authors: Lakens Daniel
Published: December 2023

As the practice of preregistration becomes more common, researchers need guidance in how to report deviations from their preregistered statistical analysis plan. A principled approach to the use of preregistration should not treat all deviations as problematic. Deviations from a preregistered analysis plan can both reduce and increase the severity of a test, as well as increase the validity of inferences. I provide examples of how researchers can present deviations from preregistrations and evaluate the consequences of the deviation when encountering 1) unforeseen events, 2) errors in the preregistration, 3) missing information, 4) violations of untested assumptions, and 5) falsification of auxiliary hypotheses. The current manuscript aims to provide a principled approach to deciding when to deviate from a preregistration and how to report deviations from an error-statistical philosophy grounded in methodological falsificationism. The goal is to help researchers reflect on the consequence of deviations from preregistrations by evaluating the test's severity and the validity of the inference.

Published: December 2023

Conduct problems in childhood affect the daily lives of children and their families and have serious economic implications for society. The Incredible Years parent program (IY) is a manualized behavioral parent training that aims to improve parenting skills in order to reduce conduct problems of children. We conducted a cost-effectiveness analysis of IY, compared to care-as-usual (CAU), in preschoolers at risk for a chronic pattern of conduct problems. In a case-control design with a two-year follow-up, we assessed intervention costs, use of public services (e.g., healthcare and special education), property damage, travel costs, and parental productivity losses. Conduct problems reduced in children in the IY condition, relative to CAU. From the public authorities perspective, the net costs to reduce the child’s conduct problems by one point of observed conduct problems (meaning a reduction of one disruptive behavior each 20 minutes) were €187. Taking the parents’ perspective and the societal perspective it was €88 and €155, respectively.

Algorithmen und Daten in kulturwissenschaftlicher Forschung
Authors: Franken Lina
Published: December 2023

This article outlines a research programme for the specific perspective of empirical cultural studies in the digital humanities. As six areas of digital humanities in application, it elaborates computational methods and algorithms, digital and digitised data, infrastructures, resources, digital handcraft and basic digital skills. These are combined with perspectives of reflection, especially in relation to algorithmic assemblages, practices in the community of practice, infrastructures and resources as power structures, and data in its changeability and incompleteness. Due to researchers’ fear of algorithms and data, these areas have so far only been realised in rudimentary form. However, it is precisely with the expertise of empirical cultural studies that uncertainties and misunderstandings can be used productively to further develop existing approaches, expand them to meet the needs of cultural studies and iteratively connect them with cultural analytical concepts. Possibilities and implications cannot be explored with tools and scripts as a transfer of existing methods into digital procedures. These change approaches to knowledge that can be realised in close human-technology relations combined with computational thinking.

Authors: Jaafer Duaa , A. Mahdi Samira
Published: December 2023

The aim of this in vitro study was to analyze the effect of a blue light (λ = 420 – 480 nm), a single-walled carbon nanotube -OH, and their combination on the viability (cytotoxic or enhancement) of the skin cancer A431 cell line after 24 hours of incubation periods. Cell culture is the process of removing cells from living tissues and growing them in a laboratory setting until they are ready to be tested using photodynamic therapy and nanoparticles, which is known as direct irradiation in vitro. Skin cell plates (A431 cell line) grown in culture medium supplemented with 10% fetal bovine serum (FBS) were irradiated with blue light, treated with the nanoparticle, and treated with the combination of them, and plates were incubated for 24 hours. In all the experiments, a crystal violet assay was used to determine the viability of the cells, and the intensity of color was measured by a plate reader. The cells were kept at 37°C. Blue light results showed a considerable decrease (p≤0.001) at 240 seconds after 24 hours of incubation time in viability percent; nanoparticle results showed a considerable decrease in the viability percent  (p≤0.001) for all concentrations; the most effective concentration was 200 µg/ml; and the combination results showed a significant decrease in cell viability percent (p≤0.001)  for all concentrations as compared with the control group. The single-walled carbon nanotube- OH with a concentration of 200 µg/ml produced the greatest results when combined with a light exposure period of 240 seconds.

The Impact of Depression on Life Satisfaction through the Mediation of Grit and Self-evaluation of Academic Performance: Focusing on the Differences between Middle School and High School Freshmen
Authors:   The Education Research Institute, Hur Young Ju
Published: December 2023

The purpose of this study is to determine whether grit and academic performance self-evaluation doubly mediate the effect of depression on adolescents' life satisfaction, and to verify whether this relationship differs between first-year middle school students and first-year high school students. To achieve the purpose of this study, latent mean difference and multi-group structural equation analysis was conducted using the 4th year of data surveyed in 2021 among the 2018 data of the Korean Children and Youth Panel Survey(KCYPS). The results of the study are as follows. First, high school students had significantly higher levels of depression and lower levels maintaining interest and sustained effort of grit, self-evaluation of academic performance, and life satisfaction than middle school students. In particular, it was found that high school students' self-evaluation of academic performance and life satisfaction were very loudly lower than middle school students. Second, in both the first year of middle school and the first year of high school, life satisfaction was low when depression was high. However, it was found that if the level of sustained effort of grit and self-evaluation of academic performance improves, the negative impact of depression on life satisfaction can be reduced. In addition, it was found that only when the level of maintaining interest of grit improves simultaneously with the level of self-evaluation of academic performance can the negative impact of depression on life satisfaction be reduced. Furthermore, It was also found that in order to increase life satisfaction, we must focus on improving sustained effort of grit for first-year middle school students, and we must focus on simultaneously improving of maintaining interest of grit and self-evaluation of academic performance for first-year high school students. Based on these research results, this study was proposed to provide a grit promotion program and self-exploration program appropriate for each school level, in order to increase life satisfaction of first-year middle school and first-year high school students.

Published: December 2023

Focus groups allow researchers to collect data from multiple participants on a set of questions while simultaneously observing participant interactions during sessions. Traditionally, researchers conduct focus groups in person, though online focus groups have been increasingly used as technologies have improved. The pandemic increased the need for researchers to innovate online focus group practices. This paper aims to present best practices for using annotation functions on digital video conference platforms to conduct focus group interviews in veterinary medicine education research. We explain how Zoom, specifically its Annotate functions, offers a useful tool to facilitate online focus groups and assist veterinary medicine education research and practice. This method addresses many of the challenges that in-person focus groups have—dominant participants, geographical barriers, and confidential (instead of anonymous) participation—while still being able to collect quality data during a group interview. The best practices described here allow for capturing both qualitative and quantitative data from online participants while preserving their anonymity and increasing the ease of participation. Based on data we have collected, participants report being comfortable providing honest and direct responses across a variety of questions. This practice also allows the collection of simultaneous or delayed answers, which means that participants have more flexibility in how and when they respond compared to many in-person focus groups. This practical approach to online focus group research can assist in conducting veterinary medicine education research not just during the pandemic but whenever geographical barriers or a need for increased confidentiality are researcher concerns.

Authors: Myslavskyi V.
Published: December 2023

The scientific relevance. The formation and development of the newsreels and documentary films in Ukraine in the 1920s remains one of the least researched pages in the history and development of Ukrainian cinema. That is why the relevance of this research lies, mainly, in filling a significant gap in the history of Ukrainian cinema. A detailed study of newsreels and documentary films production will allow to reveal trends in the development of the Ukrainian film industry in the 1920s in the field of documentary films.

The purpose of the article is to study the specifics of the VUFKU policy on strengthening the material and technical base of Ukrainian film production during the 1920s, to study and analyze the history of the formation and development of the production of newsreels and documentary films in the specified period.

The methodology of analysis of the problem consists in using, first of all, the historical-systemic approach, which provides an opportunity to understand the dynamics of the development of newsreels and documentary films at a specific historical stage. The problem-chronological approach made it possible to distinguish by year the main directions of the VUFKU activity in the development of newsreels and documentary cinema within the defined chronological framework. The historical-systemic approach made it possible to understand the dynamics of the development of Ukrainian cinematography in the field of documentary cinema as a system at a specific historical stage.

The results of the research are that the article examines the prerequisites that served as an impetus for the emergence of a special technical basis for shooting newsreels. The way of development and establishment of newsreels production is considered. Genre and thematic directions of newsreels, types of newsreels, as well as the circumstances that led to the development of the production of newsreels and documentary films are analyzed. The composition, features and functions of the elements of the Ukrainian organizational and creative model of cinematography have been established.

The scientific novelty lies in the fact that the article for the first time, on the basis of a complex analysis, researches the process of transformation of structural elements of Ukrainian cinematography in order to establish the release of newsreels and documentary films.

The practical significance of the article lies in the fact that the results of the study will contribute to the filling of the “white spots” in the history of Ukrainian cinematography, in particular, the establishment of newsreels and documentary cinema as a component of Ukrainian cinematography, which contributes to the creation of a holistic concept of the development of domestic cinema, further understanding of the film production process of the past and present. The materials of the article can be used in further scientific and theoretical researches, during the creation of training manuals and separate sections of the history of Ukrainian cinema.

Introduction. Intravitreal administration of angiogenesis inhibitors for the neovascular form of age-related macular degeneration is considered the “gold” standard of treatment. One of the possible side effects of this intervention is a significant increase in intraocular pressure (IOP). Aim: Assessment of the dynamics of changes in the level of intraocular pressure in patients with neovascular age-related macular degeneration (nAMD) receiving therapy with angiogenesis inhibitors. Materials and methods: The study included 100 patients (100 eyes) diagnosed with nAMD: group 1 – 50 patients (50 eyes) who received intravitreal injection, group 2 (control) – 50 patients (50 eyes). At stage I of the study, the degree of increase in IOP in patients with nAMD after intravitreal administartion was assessed, at stage II – the effectiveness of prophylactic instillation of a 2% dorzolamide solution. Patients in group 1 received intravitreal administration of aflibercept 2 mg (Eylea®). IOP was measured with a 7CR pneumotonometer (Reichert, USA) before, 15 minutes, 30 minutes and 1 hour after injection. Results and discussion: 15 minutes after the administration of aflibercept, there was an increase in IOP levels by an average of 6.53 mm Hg. Art. (35%) from the initial value, after 30 minutes – a decrease of 5.01 mm Hg. Art. (27%) and achieving almost initial values after 60 minutes. Prophylactic instillation of dorzolamide 2% solution 30 minutes before surgery helped stabilize the normal IOP level.

Aim. To present modern views on various types of eating behavior in children and adolescents and their role in the development of obesity. Key points. Both hereditary predisposition factors and environmental factors play a role in the formation of obesity, among which eating behavior (PP) plays a significant role. Various questionnaires and scales are used to study PP disorders, one of the validated questionnaires is the Dutch Eating Behavior Questionnaire (DEBQ), which plays an important role in clinical practice, it allows you to simultaneously evaluate three main types of PP, which is important in the diagnosis of early PP disorders and contributes to the correction of identified disorders, as well as it allows to increase the effectiveness of therapeutic and preventive measures. It is also an urgent issue, especially given the limited number of medications allowed for the treatment of obesity in childhood and adolescence, is the search for approaches that can effectively treat obesity, especially in the long term, and therefore it is necessary to rely, inter alia, on knowledge of the peculiarities of eating behavior in patients in order to optimize the trajectory of treatment. Conclusion. In all cases, treatment of PP disorders should include a full, in-depth, detailed analysis of PP to understand the underlying factors and stress. Interventions should be tailored to each case, with the goal of restoring normal nutrition and nutritional intake and improving the patient's quality of life. Keywords: obesity, children, adolescents, eating behavior, Dutch Eating Behavior Questionnaire (DEBQ)

Coal is relatively cheap and abundant fossil fuel contributing to 40% of the world's electricity production. However, coal combustion generates a significant number of by-products, majority being the coal fly ash (CFA). The heterogeneous nature of CFA poses significant challenges in its value-added applications hence, requiring appropriate preprocessing treatments which are expensive and technically savvy. Therefore, this research aims to improve CFA's suitability for the application of value-added products through a technique called “washing cycles” which wash the CFA multiple times using distilled water under a controlled environment with continuous and vigilant monitoring to ensure accuracy throughout the entire process. To optimise this washing cycle process, parameters such as the number of washing cycles, stirring time, and temperature were analysed, and the results were optimised through surface response methodology. The analytical findings on the optimization process demonstrated that a suitable pre-treatment involved employing five washing cycles with a stirring time of 7.5 minutes. Furthermore, varying the temperature did not yield a substantial effect on the effectiveness of washing cycles, since the precipitation of Ca2+ ions even complicate the preprocessing. Therefore, we recommend conducting additional investigations into the efficient use of pre-processed CFA to produce value-added applications adhering to circular economy and sustainability.

Accurate characterisation of rock porosity is essential for assessing its strength and durability. This study explores both conventional and image analysis methods for determining rock porosity of two types of rocks, Bibai sandstone, a hard clastic rock and limestone, a soft rock. Conventional methods for determining rock porosity involve physical measurements and laboratory analysis, while image analysis methods utilize advanced imaging techniques such as CT scans or SEM to assess porosity based on visual information extracted from rock images. While various image analysis approaches exist to determine rock porosity, questions arise as to which approach is applicable and whether the results are comparable to current conventional methods. Hence, this study focuses on comparing the accuracy of alternative image analysis approaches. Representative rock chips from each core sample were examined using SEM, and 2D porosity was evaluated through image processing with ImageJ software. The Avizo visualisation software was employed to assess Bibai sandstone samples' porosity from CT images. The research offers insights into the pros and cons of each approach, contributing to the enhancement of accuracy and efficiency in rock porosity evaluation, particularly in geology, mining, and civil engineering applications.

Published: December 2023

The capability of certain microbial strains to uptake electrons and fix CO2 can be exploited to capture greenhouse gas and convert it into products of interest through a process called microbial bioelectrosynthesis. This study evaluated the capability of C. saccharoperbutylacetonicum N1-4 to utilize bicarbonate for growth, by both supplying electrons in a single-cell reactor and using a graphite-felt assembly as electrodes. The medium was supplemented with 4 g/L bicarbonate and 200 µM NADH. An open circuit experiment was carried out in a medium with bicarbonate and no complex nitrogen sources. The applied potential was -600 mVAg/AgCl. The impedance spectroscopy and cyclic voltammetry techniques were used to characterize and monitor the reduction and oxidation peaks. The conditions that promote the highest observed specific growth rate (0.87±0.18 h-1), were -600 mV, 4 g/L HCO3 -, and NADH. The growth rates of 0.57±0.01 h-1 were observed at 4 g/L HCO3 - without any potential input, and 0.51±0.10 h-1 at a potential of -600 mV in the presence of NADH. The results showed that an environment that provides exogenous electrons and an externally applied potential promotes the capability of C. saccharoperbutylacetonicum N1-4 to reduce CO2, as evidenced when biomass concentration and specific growth rate were increased.

Social media represent a relatively new phenomenon affecting the lives of people across the globe. Recently, the number of social media users reached billions, and this number increases every year. Previous studies indicated that excessive social media use may have adverse effects on mental and physical health. Therefore, it is important to explore what psychological factors may contribute to the excessive use of social media. It was found that social anxiety and alexithymia are robust predictors of excessive social media use. However, little is known about the role of empathy and Theory of Mind (ToM) in excessive social media use. Therefore, the primary aim of this study was to examine the mediating effect of empathy and ToM in the relationship between alexithymia and social anxiety. Collectively, 1737 subjects participated in the study (Mage = 25.28, SDage = 10, Females: 60.83%). We assessed empathy, social anxiety, ToM, loneliness, and excessive social media use. Structural Equation Modelling was used to test the mediating effect of empathy and ToM. It was revealed that there is a positive relationship between difficulty in identifying feelings (alexithymia) and social anxiety: B = 0.53 (95% CI [0.41 – 0.65], p < .001). Moreover, a significant positive association was found between social anxiety and excessive social media use: B = 0.28, 95% CI [0.14 – 0.37], p < 0.001. However, loneliness was unrelated to social media use. Similarly, there was no significant mediating effect of empathy and ToM on the link between difficulty in identifying feelings and social anxiety. Future research should examine the generalizability of our findings using different cultural/linguistic environments. The primary limitation of the study is the use of cross-sectional data which prevent to draw causal links between the explored relationships.
Mercury's xenolandscapes

The scientific understanding of such features of xenolandscape formation has been carried out, which corresponds to the filling of the scientific-cognitive synthesis of knowledge about this process with all available information appropriate to various natural sciences. At the beginning of awareness, this synthesis is xenoplanetological, with subsequent search and target xenolandscape interpretation and cartographic representation of characteristic, typical local and regional xenolandscape formations of Mercury. Predominantly medium-scale maps of such representations are, first of all, a reflection of local objects of xenoplanet landscape science. Moreover, these reflected objects are out-of-rank, that is, they have not yet been determined with respect to the ranks of xenolandscape formations, similarly formed due to the synergy of influences and interactions of different strengths, but genetically the same initial xenolandscape-forming factors of material and energy-field xenonaturals.

Whatever the general diversity of xenolandscape objects of other lithospheric planets, not the Earth, no matter how plentiful and diverse their inventory list may seem, the cosmic conditions for their appearance and the acquisition of their final forms are not rank-limited and, at the same time, essentially not differentiated - they are the same: meteorite falls , the most common example. Therefore, it is unrealistic and impossible to give even an approximate possible rank «link forward» of certain xenolandscape formations and present them as «mainly local» or «mainly lower regional» or even planetary ranks, now and further. This is due to the absence of many landscape-forming factors that are effective within the terrestrial nature, geocomponent and geofactorial, that is, material and predominantly energy, the activity of which is reduced almost to zero. But at the same time, the rank identification of each formation in particular, among all the available xenolandscape objects, is still possible – and this is not a self-contradiction here. In each specific case, and under each expressive illustration with a photo image or a model of such a xenolandscape formation, with its fixed spatial parameters (linear scale), the rank of the displayed formation is determined and indicated here under each figure.

The specificity of xenolandscape interpretations of the nature of the terrestrial lithospheric planets is a greater and more accessible performance for the synthesis of knowledge about local and regional landscape formations of xenoplanets using cartographic rather than verbal scientific models. Syntheses-descriptions of xenolandscape formations, typical for landscape scientists, are still waiting for an effective search for their scientific content.

Keywords: Mercury, planet, xenolandscape.

The article is dedicated to Y. Fedkovych as a full member of the South-Western Division of the Russian Imperial Geographic Society (1873–1876). It outlines the directions of work of this influential scientific association, which conducted, among other things, ethnographic studies regarding the study of all of Ukraine in the relevant aspect. The efforts of M. Dragomanov, an authoritative member of the Division, aimed at involving Y. Fedkovych in studies of Bukovinian Hutsulia are indicated. Starting this activity, the writer realized himself in various related forms, including purely literary ones, with colorful folklore and ethnographic content, and special research in folklore and ethnography (about customs and beliefs, calendar rituals of his fellow countrymen, etc.).

It is noted that Y. Fedkovych's membership in the South-Western Division of the Geographic Society was essentially the first official recognition of his personal contributions to the field of science.

Традиція зображення монархинь Великобританії в декоруванні тонкої кераміки кінця XVII–ХХ століть
Authors: Дєточка Ольга
Published: December 2023

Мета статті полягає в розкритті специфіки традиції зображення монархинь Великої Британії в декоруванні фарфору-фаянсу періоду кінця XVIІ–ХХ ст.
Результати дослідження. Визначено, що перші встановлені вироби з означеним штибом оздоблення датуються 1690 і 1702 роками, перший присвячений постаті королеви Англії, Шотландії й Ірландії – Марії ІІ (1689–1694). Другий ранній твір зображує її наступницю Анну (1702–1707). Водночас зацікавленість продукуванням місцевого фарфору-фаянсу з’явилася за часів королеви Шарлотти (1761–1718), що вплинуло на розвиток традиції зображення правительок Англії в оздобленні місцевих творів. З’ясовано, що звичай втілення образів монархинь набув розквіту за часів королеви Вікторії (1837–1897). Цю тенденцію зумовили такі чинники: активна діяльність і розширення асортименту британських тонкокерамічних мануфактур; пошук власних самобутніх мотивів декорування, які поступово звільнялися від впливу шинуазрі. Визначено, що масового поширення традиція зображення королев зазнала вже в період правління Єлизавети ІІ (1953–2022). Встановлено, що окреслений мотив декорування був репрезентований низкою таких знаних тонкокерамічних мануфактур і заводів Британії, як Дербі, Веджвуд, Вурстер, Споуд, Аддерлі.
Наукова новизна полягає в систематизації й уточненні інформації щодо застосування мотиву зображення монархинь в оздобленні тонкої кераміки Великобританії, зокрема періоду кінця XVII–ХХ ст.
Висновки. На основі здійсненого дослідження можна стверджувати, що мотив зображення королев є осібною віхою варіацій декорування, притаманних мистецтву фарфору-фаянсу Англії. Серед художньо-промислових осередків, які систематично зверталися до традиції зображення монархинь Туманного Альбіону, належать Вурстер, Веджвуд, Споуд, Доултон й окремі менш відомі майстерні Стаффордширу. Визначено, що ілюстрування сюжету королівських персоналій було більш притаманне оздобленню декоративних блюд, чашок і кубків, меншою мірою використовувався в декоруванні статуеток і медальйонів.
Вплив китайських фільмів про бойові мистецтва на тематику, образність і драматургію відеоігор
Authors: Чжан Ціньвень
Published: December 2023

Мета статті – виявити та проаналізувати вплив китайських бойовиків уся (wuxia) на індустрію відеоігор.
Результати дослідження. Індустрія відеоігор, яка активно розвивалася в 1980–1990-х рр., базувалася на темах і образах, популярних у масовій культурі. З середини 1980-х рр. розробники почали активно використовувати зовнішність і пластику акторів китайських фільмів уся, відтворювати характерні епізоди з відомих бойовиків, вставляти кат-сцени (цитати з фільмів). Якщо образ Брюса Лі почали використовувати у відеоіграх після його смерті, то Джекі Чан свідомо спрямував свою продюсерську та акторську діяльність на виробництво ігор. Поява масових багатокористувацьких комп’ютерних ігор стимулювала використання жанру уся в ігровій індустрії: було створено багато проєктів, де користувачі вступають в бій не з абстрактними запрограмованими перешкодами та неігровими персонажами, а з іншими живими гравцями в онлайн-режимі. З іншого боку, ігровий дизайн почав впливати на сценарну структуру фільмів уся – з’явилися різні рівні складності для головного героя, епізоди воскресіння та отримання другого життя, повернення до попереднього етапу або точки біфуркації (ситуації вибору), візуальний сторітелінг тощо.
Наукова новизна. Ця публікація вперше розкриває питання впливу китайських бойовиків уся на тематику та образність відеоігор.
Висновки. Доведено, що фільми уся вплинули на візуальну естетику, драматургію та бойову хореографію відеоігор. З’ясовано, що сучасна гейм-індустрія реагує на кожен успішний фільм уся створенням ігор на його основі; виробники франшиз у жанрі уся залучають геймінг до реклами та дистрибуції кінофільмів; оригінальні відеоігри уся розробляються як франшизи та адаптуються до кіно чи телебачення. Зроблено загальний висновок, що зв’язок фільмів та відеоігор в жанрі уся має характер взаємовпливу.

El río Hacha ubicado en Florencia-Caquetá, Colombia, abastece agua para el consumo humano y proporciona otros servicios ecosistémicos. Las actividades antrópicas han generado una presión en este recurso natural. Se realizó una valoración económica de la calidad de agua y los servicios recreativos en los balnearios del corredor vial del río. Se establecieron cuatro puntos en el tramo para medir indicadores fisicoquímicos del agua. Se realizó una encuesta en una muestra de 460 personas, cuyo análisis empleó los métodos de costo-viaje y valoración contingente. Se encontró que los indicadores de calidad de agua no exceden los límites permisibles para contacto primario. La recreación en los sitios genera beneficios económicos para la demanda local: la variación del excedente del consumidor ante un proyecto hipotético de mejora en la calidad del agua fue positiva. La disposición a pagar por hogar por una mejora en la calidad del agua asciende a $9.984,04 por año. Esto implica que existe un potencial de aprovechamiento sostenible en los servicios ecosistémicos asociados a la recreación en el recurso hídrico
