Published: October 2024

In recent years, the shift towards open-plan offices has been gaining momentum, with the aim of enhancing intellectual productivity through improved worker communication. A wealth of research has focused on the link between the acoustic environment and intellectual productivity. Yet,
the intricate factors that bridge the acoustic environment with intellectual productivity remain elusive. This study endeavors to illuminate the pivotal role of impression evaluations in bridging the gap between the acoustic environment and intellectual productivity. Through a detailed empirical
analysis conducted over six days in a real-world open-plan office, we investigated both the sound environments and the workers' impression evaluation during this period. Based on the results of the survey, an evaluation structure that represents the relationship between the acoustic environment
and intellectual productivity in open-plan offices was studied using structural equation modeling. The results of the analysis showed that workers of multi-person work were more susceptible to the effects of acoustic environment than individual workers.

Published: October 2024

To perform the coastal acoustic tomography measurement, the locations of stations should be first selected at some appropriate sites on or near the coast. When selecting the locations, it is important to consider vehicle accessibility, the presence of structures such as barges, and
the absence of obstructions to sound transmission and reception. Based on these conditions, the five stations were selected for the coastal acoustic tomography observation in Yeosu Bay of South Korea in 2023. In this observation, total six sound propagation lines were used for the inversion
of the sea current speed. The sea current speed estimated for each sound propagation line was compared to that from ADCP installed in Yeosu Bay. As a result, when the angle between a line along which the Yeosu Bay's dominant sea current flows and the sound propagation line was small, the estimated
current speed was similar to that from ADCP data. This can be considered to be because the smaller the time difference obtained from tomography measurement, the greater the impact of arrival time measurement error on the current speed. This result shows that the orientation of the lines between
stations should also be considered important for selecting the locations of stations.

Authors: OUAKKA Slimane , VAN DAMME Bart , PENNEC Yan , KOUROUSSIS Georges
Published: October 2024

Urban areas are increasingly subjected to vibrations from various sources within the urban environment. Therefore, there is an urgent necessity to find measures that can minimize their negative effects. This pa-per investigates the concept of metamaterial and analyzes the impact of
its inclusion on the range and span of band-gaps at low frequencies (up to 80 Hz), which characterize the vibrational waves in urban areas. This is achieved by developing a finite element model of the relative unit-cell and conducting a parametric investigation on the geometrical characteristics
and material properties of the inclusion. Furthermore, the depth of the embedded inclusion is also examined to understand the transition of metamaterials from seismic (with the inclusion fully embedded) to resonant ones, where the inclusion is on the surface. Finally insights are given in
order to help on the selection of the correct parameters to minimize a certain range of frequencies.

Published: October 2024

Traffic noise can cause significant annoyance. We administered noise annoyance surveys in two Florida facilities located near a highway and a busy road while traffic noise levels were being measured. In Trilogy school, thirty middle & high school students rated the annoyance caused
by traffic noise inside the school to be an average of 1.9 (SD 2.0) on a scale from 0 to 10. Traffic noise was just as disturbing as other sounds inside the school. However, the fraction of students reporting any level of traffic noise disturbance was significantly higher outdoors (80%) than
indoors (48%). Additionally, traffic noise caused some difficulty hearing the teacher for 9.7% of students. In Shands Hospital, the average ratings of annoyance from traffic noise given by 107 staff (M=1.1, SD=2.0) and 104 patients (M=1.2, SD=1.4) were not higher in areas of the hospital that
were closer to the road or the helicopter landing pad compared to the other areas of the hospital. Traffic noise was substantially less disturbing than other noise inside the hospital, e.g., tube station. However, traffic noise caused moderate to extreme annoyance for 12.4% of patients and
some degree of sleep disruption for 27.9% of patients.
Theoretical and experimental analysis of a nonlinear vibro-acoustic energy sink
Authors: GIVOIS Arthur , MOUSSA Rita , DAUCHEZ Nicolas
Published: October 2024

This study is concerned with the experimental and theoretical analysis of a vibroacoustic nonlinear system devoted to absorption application. Based on the nonlinear energy sink principle, the dynamics of the system is reduced to two coupled degrees of freedom, one of which exhibits
nonlinear behavior due to a large displacement mechanism. The set-up allows for precisely characterizing the nonlinear function of the mechanical system, first uncoupled and then coupled with an acoustic and linear resonator. Continuation procedures are performed experimentally and numerically,
respectively using a phase-locked loop (PLL) and the asymptotic numerical method implemented in the MANLAB software package. The comparison between theoretical predictions and experimental results obtained on the uncoupled system allows for a parameter identification of the nonlinear resonator.
Measurements on the coupled system highlight the energy pumping phenomenon, which can be predicted from numerical predictions in which identified parameters are introduced. The procedure aims at proposing analytical models for achieving efficient level attenuation, and providing design guidelines
for sound reduction at high levels in confined spaces.

Published: October 2024

New highways have been introduced into Kosovo landscape in recent years. The trajectory of the highways crosses through the fields and in the middle of some previously remote rural settlements. This has changed the environment for these areas and the environmental noise is a major concern.
This study aims to estimate the population exposed to high traffic noise levels around the highway routes in Kosovo. GIS has been used to model the highway lines, the terrain and the buildings on site. Roadside traffic noise measurements as well as traffic flow measurements have been conducted
to approximate the noise sources. An approximate noise map has been generated for the studied area. The population exposed to daytime and nighttime road traffic noise were estimated. The results show the need for road traffic noise reduction measures and areas where they are most needed.

Published: October 2024

Regulatory guidelines mandate strict noise levels during concerts, specially for night leisure soundscapes, yet accurate compliance assessment is hindered by the presence of extraneous noises. This paper presents a methodology focused on creating a specialized dataset tailored to address
this challenge. We have captured several live concerts, ensuring the dataset's relevance and applicability in noise compliance assessments. This paper exposes the methodology followed since the deployment of the sensors until the labeling of the most relevant parts of it by using the LAeq
levels to select the most prominent sound sources. The dataset has been used to use a PANN and incorporate a classification mechanism into a noise monitoring platform for live concerts. By leveraging LAeq levels to identify prominent sound sources, our methodology ensures the inclusion of
key acoustic events in the dataset, facilitating subsequent analysis and classification tasks. The integration of a PANN (Pretrained Audio Neural Network) enables the development of a robust classification mechanism tailored to the intricacies of live concert environments. This work underscores
the importance of specialized datasets in addressing the challenges of noise compliance in concert settings, offering a modest resource for advancing research and practical applications in this field.

Published: October 2024

Nowadays, multirotor drone usage has become widespread for various purposes: amateur or professional videos, building inspection, civil security, military defense, etc. But this usage increase has also seen growing concerns about community noise annoyance in inhabited areas, acoustic
detectability for security and military purposes, or remote wildlife monitoring. Predicting the drone noise can now be accurately achieved thanks to computational aeroacoustics (CAA). The present work deals with the aeroacoustic simulation and measurement of a quadcopter drone and in-flight
condition prediction. The CAA simulation of a single rotor is first compared with test bench measurements in an anechoic room. Comparison for the full drone is then derived from this single-rotor comparison. Finally, the study is further extended to in-flight comparisons, in order to show
that CAA simulation can help design quieter drones in real operating conditions.

Wind Turbine Noise (WTN) variability is often related to the influence of local micrometeorology as well as to space and time variations in the ground properties. Thus, the PIBE Project (2020-2024) aims to estimate these variabilities and their associated uncertainties. Its objective
is to enable engineering companies or wind farm developers to estimate more accurately the risk of noise. In the WP2 of the PIBE project, 3 approaches are explored: (i) a NUMerical approach through the development of a metamodel, (ii) an EXPerimental approach through a major in-situ measurement
campaign lasting more than 1 year, and (iii) a STATistical approach consisting in the evaluation of WTN variability. The NUM approach consists in sound emission calculation of each wind turbine using the Amiet's theory, and sound propagation calculation using a wide-angle Parabolic Equation
(WAPE) modelling. The EXP part of the PIBE project has led to the development of a large database, accessible via a dedicated Shiny application. The last approach (STAT) has been carried out using both an open-access online tool called WindTUNE and an open-source tool based on Code_TYMPANTM,
namely OCP. The 3 approaches (NUM + EXP + STAT) are presented and the corresponding results are discussed.

Published: October 2024

One of the objectives of the European JPI Oceans DeuteroNoise project is to investigate the soundscapes within different sea basins. Measurement campaigns, including the recording of raw noise data (wave files), have been carried out in the Venice Lagoon, in the North Adriatic and on
Barcelona shore. In this work we will present the first results. The data acquired were processed to obtain the characteristic spectrum and noise levels; subsequently the velocity of the particles will be acquired and analysed. The analysis of the recorded data involves the design of a taxonomy
of anthropogenic noise sources, e.g. large ships, small boats or any other existing noise source. The recorded data were labelled with these sources, describing their main audio characteristics (spectral distribution, temporal evolution, etc.) for their characterization and future blind identification.
Throughout the measurement period, ship and route data were acquired using AIS (Automatic Identification System) and Vessel Monitoring System (VMS) in the measurement sites. The preliminary analysis and labelling, together with ship and route data, will allow the reproduction of acoustic environments
of anthropogenic origin in laboratories and the creation of acoustic maps of the basins investigated using commercial software.
A fundamental study on energy-based assessment of Shinkansen railway noise in Japan
Authors: KATAYAMA Mayu , HARADA Kazunori , MARUYAMA Naoya , SUGAHARA Akiko , HIRAGURI Yasuhiro
Published: October 2024

This study examines the assessment of environmental noise standards for the Shinkansen in Japan, which predominantly relies on averaging the highest noise levels, specifically L_(A,Smax) obtained from actual measurements taken at key locations along the Shinkansen routes. In contrast,
the international approach, based on Europe, typically involves energy-based evaluations that calculate noise exposure over time using estimated values. By investigating the correlation between L_(A,Smax) and energy-based noise levels (L_AE), including data from the latest Shinkansen model,
the N700S, this research aims to explore the potential for adopting energy-based noise assessments in Japan, aligning with international methodologies. Additionally, it compares the relationship between measured L_AE and L_(A,Smax) with that of estimated L_(A,Smax) and measured L_(A,Smax).
The study also examines the calculation equations by derivingL_(A,Smax) from L_AE and considers factors contributing to the increase in Root Mean Square Error (RMSE), such as differences in routes, distances from the track surface to the measurement points, vehicle types, and the influence
of building clusters.
A high-resolution acoustic goniometer for characterizing sound diffuser reflections
Authors: XIANG Ning , CHEN Ziqi
Published: October 2024

Noise control engineering and architectural acoustics practice have widely applied diffusing elements and devices to create surface scattering and diffuse reflections. An acoustical goniometer in the form of a circular microphone array has been used to characterize scattered responses
for various types of diffusing elements/devices. This research is also intended for experimental validation of diffraction simulations of diffusing devices based on the physical theory of diffraction (PTD). To cope with experimental challenges, particularly for the research in the physical
theory of diffraction, an acoustic goniometer must achieve a high enough angular resolution in addition to fulfilling far-field requirements. This paper discusses practical implementations and experimental results of portable goniometers with a radius of up to five meters and an angular resolution
of 1.25 degrees. The practical implementation is intended to be easily deployable in empty, indoor spaces of sufficiently large dimensions for scattered reflection characterization. This paper discusses an effort of increasing experimental efficiency of characterization procedures for oblique
incidences.

Published: October 2024

In this study, a field experiment was carried out in a kindergarten classroom for 5-year-olds where a small spaces for calming down were installed. The small space has a box shape for one person with a width, depth, and height of 42, 57, and 74 cm, and two units were installed with
different inside sound-absorbing conditions. The noise attenuation due to the small space was about 6 to 7 dB above 500 Hz bands with additional internal sound absorption. The experiment was performed for two months in a room with short and long reverberation, respectively, during which the
use of the space was automatically observed using a mat sensor and the room sound was recorded at the same time. As a result, the frequency and duration of use of the spaces increased in the room with longer reverberation. Also, the duration of use of spaces with internal sound absorption
tended to be longer.
Sound insulation characterisation of innovative natural ventilated façade in the context of living lab installations
Authors: SHTREPI Louena , GERBOTTO Andrea , FAVOINO Fabio , ASTOLFI Arianna
Published: October 2024

Building acoustic standards like EN 14351 and ISO 10140 regulate the measurement of sound insulation of transparent elements, with indications of the test sample dimensions, test conditions, and criterions of adaptations of the results to different on-site conditions. However, given
the research on innovative transparent building envelope including internal ventilation as double skin facades, these methodologies present limitations related to the characterization of the high variability of operating conditions in real in-field conditions. To this aim the acoustic performance
could be explored with more flexible methods inside the multi-domain context of Living Labs, which present an opportunity for multiple characterizations and testing costs reduction. This work investigates the possibility of using the sound-intensity probe method to evaluate the airborne sound
insulation of a transparent building element with internal ventilation. For this purpose, a comparative measurement campaign has been performed on the same building element installed in two Living Labs. The results show good compatibility between the different measurements and scales supporting
the application of this methodology for comparative studies in the perspective of innovative building components measurements, and the application in Living Labs.

Published: October 2024

Binaural beats are perceived when two different frequencies are presented dichotically to a listener, causing the perception of a beating sound. They have been associated with beneficial effects on cognitive functions such as learning, concentration, and creativity. Studies however
often yield incomparable or inconclusive results, due to inconsistent methodologies. Through a systematic examination, following the Garcia-Argibay Protocol, we aim to provide a more detailed understanding of the effects of binaural beats in music on cognitive functions. Specifically, we will
compare auditory stimulation with music containing binaural beats of the alpha and gamma frequencies to a control condition presenting music without binaural beats. We will measure the differential effect of 12 Hz and 40 Hz binaural beats on working memory performance, operationalized through
the N-back task, and investigate the impact of these frequencies on concentration levels measured via the global-local task. Lastly, heart rate will be used as a continuous measurement throughout the experiment in order to evaluate the effectiveness of the different frequencies in inducing
calmness.
Natural ventilation and acoustic privacy in settlement cores: a review of window technology and night-time economy planning policy
Authors: COOKE J. T.
Published: October 2024

This study reviewed the potential of partially open windows to address the challenges of natural ventilation and night-time airborne noise within settlement cores. These areas, which often feature historic buildings, require sensitive interventions to balance the conservation of heritage
with the need for liveable, sustainable cities. The 'night-time economy' (NTE) encompasses a diverse range of businesses, services, and events that operate beyond traditional daytime hours, such as restaurants, bars, nightclubs, entertainment venues, cultural events, and 24-hour services.
Night-time noise disturbances can be detrimental to residents' health and well-being. A case study examined the solutions proposed by contemporary NTE planning policy to address night-time noise in settlement cores, particularly in instances where the expansion of NTE areas and extended trading
hours are considered. No physical solution mitigation strategies for noise reduction were identified in the NTE policy, and only a management approach was proposed. This study examines the potential of innovative acoustically attenuated partially open windows as a strategic solution to airborne
night-time noise pollution from a night-time economy. This solution may improve energy efficiency and sustainability in cities while allowing the night-time economy and residential areas to coexist more harmoniously.

Published: October 2024

A mechanism for solving the urgent problem of forecasting technical impacts and residual life depending on operating time is presented. It is proposed to use the theory of multiple regression analysis as a methodological basis, provided that the factors can be both independent, controlled, and dependent and uncontrollable, their combinations cannot be fully realized, and the objective function is measurable. The factors used are the values that determine the operating mode: the speed of the crankshaft, temperature, engine load. Such a task in the article is called the second forecasting task by the authors. The practical implementation of this mechanism is carried out using the example of constructing a multiple linear regression model of the dielectric constant of a high-speed diesel engine oil.

Vigor–Organization–Resilience Framework for Assessing Ecosystem Health in the Qinghai–Xizang Plateau
Authors: Yang Junliu , Xin Zhongbao , Li Xiaoyu , Liang Xiaoyu
Published: October 2024

Ecosystem health (EH) assessment is vital for understanding and improving the state of ecosystems. Analyzing the geographical and temporal evolution and predicting future EH trends under land-use changes deepens our understanding of regional ecosystem dynamics. This method offers valuable insights for managing and sustaining ecosystems, highlighting the importance of incorporating land-use changes in EH assessments. In this study, the CA-Markov model is used to predict future vegetation and land use in 2030. Additionally, it utilizes the vigor–organization–resilience (VOR) framework to evaluate the current and future health of the Qinghai–Xizang Plateau (QXP) ecosystem. The analysis is based on vegetation and land-use data from 1980 to 2020. EH is unhealthy in most areas of the QXP, with 63.17% of the area in grades “seriously unhealthy” and “generally unhealthy”, 18.30% in grades “sub-healthy”, only 18.53% in grades “generally healthy”, and none in grades “pretty healthy”. The EH of the QXP deteriorated markedly between 1980 and 2000 due to factors such as overgrazing and indiscriminate logging. The EH of the QXP reached its lowest point in 2000 and has been gradually improving since then due to ecological engineering and environmental awareness. Based on the 2030 projection, the area of healthier ecosystems (“generally healthy” and “pretty healthy”) on QXP will reach its highest value. The results provide a new research tool that can markedly broaden the time series for EH studies and effectively inform current and future ecological development on the QXP.

Improving the adsorption efficiency of porous adsorbent materials for organic liquids with high viscosity is crucial for addressing oil spill incidents. In this study, a high-performance aerogel adsorbent composed of polyimide (PI), hydroxyapatite nanowires (HAPnws), and reduced graphene oxide (rGO) has been fabricated, which leverages reduced flow tortuosity through anisotropic structures and solar-assisted viscosity reduction via photothermal materials. The prepared anisotropic PI/HAP/rGO aerogel, with directional channels, shows unique mechanical properties with high stiffness along the axial direction and compressibility along the radial direction. PI/HAP/rGO, featuring vertically aligned channels, demonstrated superior adsorption efficiency (the adsorption coefficient

for an engine oil with a viscosity of ~144 mPa·s) for oil of varying viscosities compared to similar aerogels with uniform pores, because of the substantially reduced flow tortuosity. The photothermal properties of rGO further enhance the adsorption speed of PI/HAP/rGO for viscous oil under sunlight, including crude oil with ultrahigh viscosity. In addition, PI/HAP/rGO exhibits excellent fire resistance, allowing for reusability via both adsorption–compression and adsorption–combustion cycles. The robust and compressible PI/HAP/rGO aerogels with high adsorption efficiency for viscous oil and fire resistance represent an ideal solution for practical oil spill treatment, and this approach also offers inspiration for the development of advanced adsorbent materials.

Published: October 2024

This study investigates a novel method of instructing interior architecture students on building specifics pertaining to walls by utilizing the combination of virtual reality (VR) and game-based learning. The creation and application of a virtual reality game called "VR ConstructED," which aims to improve knowledge of wall construction methods, materials, and design consequences, is the study's focus. This project intends to improve students' understanding of wall-related construction elements and their applicability in real-world circumstances by utilizing the immersive and interactive properties of virtual reality technology in conjunction with gamification methods. Through a case study involving academic staff and students at Bahçeşehir University, the efficacy of this pedagogical strategy will be assessed. Using a mixed-methods approach, the study collects quantitative data from surveys and qualitative data from semi-structured interviews. These questionnaires will evaluate the academic performance, contentment, and VR game participation of the students. The main goal is to clarify the advantages and difficulties of using virtual VR to teach construction features, such walls, so that curriculum designers and teachers may make informed decisions. Additionally, by illustrating how gamification and the integration of VR technology may greatly improve student engagement and academic achievement, this study hopes to contribute to the larger area of design education. The results of this study are anticipated to add to the body of knowledge in architectural education and stimulate more research into specific VR applications for design pedagogy.

Published: October 2024

The widespread dissemination of contradictory information through various media platforms can increase anxiety and confusion among younger generations. This highlights the need to promote Media Literacy (ML) skills, enabling them to evaluate online information's validity critically. Video game-based learning can be valuable in this context, fostering active learning and critical thinking. Therefore, developing and sharing innovative resources like interactive content and video games is crucial to enhancing young people's ML skills and resilience to disinformation. The YO-MEDIA project, involving three universities in Italy, Portugal, and Spain and a journalist association, aims to develop ML in young people during times of crisis (e.g., pandemics and wars) through game-based learning strategies and professional training. The project carried out 29 semi-structured interviews in the partner countries with various stakeholders to understand perspectives on media design practices and ML formulation for young people in crises. These interviews aimed to collect education and media professionals' insights on promoting ML and critical thinking among youth during crises. It also seeks to gather best practices and understand these professionals' challenges when fostering ML among youth. This study's findings suggest that the interviewees deem ML vital for distinguishing accurate information from misinformation during crises, especially relevant for young individuals. Essential skills for these young people include critical thinking, filtering information, and recognizing online threats. Effective strategies involve operating within digital environments frequented by young people, encouraging critical thinking, and nurturing collaboration. Professionals face challenges such as a lack of training, engaging young people's attention, and keeping pace with digital environments. The interviewees also emphasized the importance of ML training for informal educators and media professionals. They recommended Massive Open Online Courses (MOOCs) for their flexibility and accessibility. According to the interviewees, an ML game should involve research, interpretation, and decision-making processes and be accessible to young people with disabilities. They identified several ML projects and resources, including multimedia labs, youth parliaments, and critical thinking tools. This study contributes to developing games that promote critical thinking and ML in young people. It also aids in establishing ongoing professional training in ML for informal educators, teachers, media professionals, and other stakeholders.

School bullying is a phenomenon of great concern worldwide, with profound implications for the emotional development of those involved. Leveraging the interactive nature of game-based learning provides a unique opportunity for active student engagement that goes beyond traditional pedagogical methods. This article aims to explore students' perceptions of bullying and present a digital game as an alternative educational approach to raising students' awareness, empathy, and empowerment. Furthermore, it will be demonstrated how an art-based virtual museum game engages students in exploring and understanding the phenomenon. A needs assessment on bullying was conducted on a student population sample during the school year 2023 - 2024. Subsequently, a digital 3D escape room type game (named "e-BOB") was used, which was redesigned and reconstructed by the students from an initial project within the Panhellenic Students Competition of Onassis Foundation "Hack the Art: Yiannoulis Halepas". The game was developed using Unity, Blender, and Krita platforms and is set in an art museum. Players interact with the sculptor's exhibits through micro-scenarios and quizzes drawn from the sculptor's life and artwork that tackle the issue of bullying. Key game features include goal achievement within a time limit and discovery of hidden elements. The analysis of the needs assessment data found that all students had been involved in bullying behaviors either as victims, perpetrators or observers. The majority of students focused mainly on direct forms of bullying and less on indirect forms, and most were unable to distinguish bullying from 'simple teasing', demeaning bullying behavior. Those at greater risk are the ones who show some element of differentiation in relation to the stereotypes of the social context in which they live. Several students indicated that the school environment needs to address the issue sufficiently. Finally, the game contributed to students' empathy about bullying, enhancing their self-reflection and managing strategies. Raising awareness, mental empowerment, and empathy for bullying requires dynamic and innovative approaches. With its potential for self-awareness and student activation, game-based learning should be incorporated into educational programs for bullying prevention and management within schools.

This proceeding is an ongoing doctoral dissertation that will examine the effect of a serious game on bullying participant roles and social-emotional well-being. "This serious game, which is called TheraBuddy, is a Turkish interactive visual novel that is aimed at helping children and youth using cognitive-behavioral counseling and solution-focused counseling techniques." The protagonist of TheraBuddy is the player. According to story, the player is transfered to a school where bullying incidents occur. The player makes friends named Elma, Den, and Lu at this school. The player’s goal during the story is to offer solution-focused or cognitive-behavioral help to friends involved in bullying incidents, whether as victims or perpetrators. TheraBuddy consists of nine parts, including an introduction and eight chapters. Throughout the story, two characters named Ozguro and Bilgin help the player make choices, and the story of TheraBuddy continues according to the player’s choices. TheraBuddy was coded and hosted using the Ren'Py game engine. Characters and backgrounds were designed through Canva, and the TheraBuddy characters were voiced using Elevenlabs AI Voice Generator. As a result, an interactive anti-bullying game that is currently only playable offline has been developed. Work is currently being done to make this offline game a web-based game. It is believed that TheraBuddy will be helpful in combating bullying and strengthening students socially and emotionally. In the future, when the online version of TheraBuddy is completed, this belief will be tested under experimental conditions.

Businesses' ecosystems are ever-changing. In this highly competitive era, manufacturing Small-Medium Enterprises (SMEs) are gradually transforming their business operations with state-of-the-art digital technology. This study has established how digital technologies, such as big data analytics, the Internet of Things, and chatbots technologies, affect the business performance of manufacturing SMEs. However, the business performance of manufacturing SMEs is greatly impacted by digital technologies. The purpose of this research is to investigate how digital technologies affect manufacturing SMEs in emerging nations. The goal of digital technology influence is to boost manufacturing SME productivity. In order to find pertinent materials on the topic, this study's technique, which focuses on document analysis, is qualitative.  Nineteen empirical papers were used in arriving at the objective of the study through the database of Web of Science, Google Scholar, and Scopus through keyword search. It was discovered that digital technologies significantly enhance the business performance of manufacturing SMEs. The current study has provided new directions, insights and structure for future studies since there is little research on digital technology on manufacturing SMEs. Additionally, the research will assist leaders in their efforts to defend the expenditure of funds on the construction of technology infrastructure for their organizations.

Цель. Оценить кровопотерю, болевой синдром и безопасность применения холодной плазмы при удалении небных миндалин интракапсулярно и экстракапсулярно. Материалы и методы. Объектом исследования стали 58 пациентов с диагнозом «хронический тонзиллит, декомпенсированная форма». Пациенты были разделены на 2 группы по 29 человек в каждой. В 1-й группе выполнялась интракапсулярная коблационная тонзиллэктомия, во 2-й – экстракапсулярная коблационная тонзиллэктомия. Интраоперационно оценивались объем кровопотери и время, затраченное на операцию. В течение 10 дней регистрировались случаи ранних и отсроченных кровотечений и уровень боли. Результаты. При проведении коблационной тонзиллэктомии как интракапсулярно, так и экстракапсулярно объем интраоперационных кровотечений составил v 1,6 мл в первой группе и v 2,1 мл во второй группе; время, затраченное на операцию, при интракапсулярной тонзиллэктомии составило t 24,7 мин., при экстракапсулярной t – 4,3 мин. Заключение. Боль в послеоперационном периоде была меньше у пациентов, которым небные миндалины были удалены интракапсулярно. Время, затраченное на оперативное лечение, больше при интракапсулярном методе ввиду более деликатного удаления ткани.

Purpose. To assess blood loss, pain and the safety of using cold plasma when removing palatine tonsils intracapsularly and extracapsularly. Materials and methods. The subjects of the study were 58 patients diagnosed with chronic tonsillitis, decompensated form. The patients were divided into 2 groups of 29 people each. In the 1st group, intracapsular coblation tonsillectomy was performed, in the 2nd group, extracapsular coblation tonsillectomy. The amount of blood loss and the time spent on surgery were assessed intraoperatively. Incidents of early and delayed bleeding and pain levels were recorded over a 10-day period. Results. When performing coblation tonsillectomy both intracapsularly and extracapsularly, the volume of intraoperative bleeding was v=1.6 ml in the first group and v=2.1 ml in the second group, the time spent on surgery for intracapsular tonsillectomy was t 24.7 minutes, for extracapsular tonsillectomy t – 4.3 min. Conclusion. Pain in the postoperative period was less in patients whose tonsils were removed intracapsularly. The time spent on surgical treatment is longer with the intracapsular method, due to more delicate tissue removal.
