Analyzing classroom interactions focusing on IRF patterns and turn-taking
Authors: Hidayatullah Efendi
Published: September 2024

This study aims to analyze patterns of interaction and turn-taking in the context of classroom learning using a classroom discourse analysis approach. This research focuses on understanding the communication dynamics between teachers and students and identifying dominant patterns during the learning process. The method used is qualitative, with data collection through observation using video recorder instruments in class XI SMK Muhammadiyah Mertoyudan. The research participants were a teacher and class XI students of SMK Muhammadiyah Mertoyudan, totalling 24 students, consisting of 1 teacher and 23 students. The data results show the sequences developed from the questions between teacher and student interactions. The results of this study support the view that the discursive role of the Feedback sequence in IRF (Initiation-Response-Feedback Sequence) is to develop dialogue between teachers and students. The findings of this study on the IRF pattern are that the teacher dominates the communication in the classroom 63,4% and students 36,6%. The findings indicate that the non-delivery of learning is the main problem of students' lack of understanding of the material, lack of students' ability to think critically, and responsiveness to students. These findings can be used to develop more inclusive and effective teaching strategies that pay attention to a more balanced distribution of talk time and interaction between teachers and students. This research contributes to the literature on Classroom Discourse Analysis by filling the knowledge gap on the classroom's interaction pattern and its implications for teaching practices with feedback in IRF. The results of this study can provide valuable insights for educational practitioners and help improve students' critical communication strategies in the classroom.

Experiencia del sentir en la arquitectura vernácula en la ciudad de Cochrane, Región de Aysén, Chile
Authors: De la Rosa González Catalina
Published: September 2024

En el presente artículo se abordará el análisis y estudio de obras arquitectónicas vernáculas de la comuna de Cochrane, a través de un recorrido que conlleva desde la materialidad utilizada por los primeros pobladores de la zona para asentarse en tierras inhóspitas y extremas, pasando por la sensación que nos produce la construcción misma, hasta los símbolos que estos crean para ser reconocidos en el tiempo. La materialidad será nuestro primer acercamiento hacia la percepción del entorno próximo, el Paisaje, dado por su condición geográfica. De esta forma, se puede entender que, pese a que los signos son una formación cultural, la memoria que se genera por estos en cada uno es subjetivo y propio. Es decir, se asimila lo observado para integrarlo a la percepción individual: aprehensión fenomenológica. La experiencia en el lugar nos invita a comprender relaciones sensitivas del humano y la naturaleza fenomenológica, deconstruyendo la visión antropocéntrica donde no hay sensibilidad con el medio, dando un sentido más íntimo e intuitivo al habitar.
Es así como esta investigación se plantea como una sistematización de una experiencia donde la observación y el registro de los modos de habitar propios del sur de Chile, en la ciudad de Cochrane, región de Aysén, dan pie para una tipología inicial del habitar, derivada de los casos de estudios seleccionados.
Academia y ciudad
Authors: Duarte M. Pablo Patricio Iván
Published: September 2024

Este artículo busca reflexionar acerca de los actores y factores responsables de la ausencia o escasa relación en el diálogo entre la academia y la ciudad. Esa es la principal materia que pretende abordar este estudio, además de documentar la producción de un gesto editorial de la revista COTA, que intenta colaborar en el encuentro entre ambas instancias para propiciar un crecimiento intelectual, cultural y democrático de la sociedad en la ciudad.
Revista COTA ha sido comprendida, desde sus inicios, como una publicación académica y profesional sobre la ciudad, pero dedicada al público general. Esto marca una diferencia con otras publicaciones del mismo ámbito, pues se plantea fomentar la apertura del conocimiento sobre la actualidad de nuestra ciudad y arquitectura en una publicación innovadora y creativa, así como constituirse en un instrumento de difusión de trabajos generados, tanto en el ámbito académico como en el desarrollo profesional de cada disciplina. Estimular en el ciudadano la lectura de la visión crítica y la construcción de una mirada multidisciplinar sobre la ciudad para fortalecer su compromiso hasta mejorar la convivencia con el espacio habitado.
A la fecha, ya son 20 números publicados, con tres mil ejemplares hasta la edición nº11 y luego, en tirajes mas acotados por número. Surge, así, la necesidad de evaluar y hacer un seguimiento de la puesta en marcha del proyecto Revista COTA; si ha logrado cumplir con los objetivos editoriales, identificando, por ejemplo, los criterios de evaluación de distintos grupos, tales como columnistas, lectores y grupos académicos. Con esto se busca potenciar el medio y proyectarlo, según los resultados de la evaluación. Lo anterior se plantea, también, como un modo de pasar de lo mono disciplinar a lo multi o trans-disciplinar, en un espacio que permita una mirada más colaborativa entre las especialidades, siempre desde el rol de la arquitectura como disciplina madre que invita a desarrollar temáticas que le son propias, pero convergentes con otras.

Authors: Hidayat Sidiq Syamsul , Abdillah Umar Fachri , Mujahidin Irfan , Asyari Rifa Atul Izza , Prabowo Muhammad Cahyo Ardi
Published: September 2024

As area surveillance technology, the camera is still suboptimal because it cannot detect suspicious human movement and there is no real-time security alert. Although motion detection is implemented, it is only activated when a person passes the PIR sensor, triggering the camera to capture the object. Due to its lengthy process, it is less effective. This study aims to develop a home surveillance system that uses object detection technology to detect unusual human movements. The system is also equipped with real-time early warning through a Telegram Messenger application. The system is then tested using various parameters that may impact the precision of detection results, including object poses, camera height, and camera distance. The system can detect objects that make unusual movements in 69 images or 57.5% of the tests, based on the analysis of 120 test data. Through the integration of object detection technology and real-time Telegram-based alerts, this home surveillance system significantly demonstrates the capability to accurately identify suspicious human motions thereby enhancing area surveillance effectiveness and adaptability to various environmental conditions.

Published: September 2024

Road crack detection is critical to road infrastructure maintenance, requiring sophisticated and accurate approaches. This research explores the utilization of a combination of Wavelet and Convolutional Neural Network (CNN) methods to improve efficiency and accuracy in detecting cracks in road images. The wavelet method was chosen for its capability to capture information at different scales, enabling improved feature extraction. Meanwhile, CNN was utilized to comprehend the spatial context and tackle image complexity. The research involves several stages, including data collection, pre-processing, decomposition using the Wavelet method, forming of the CNN architecture model, training, testing, and evaluating the result. The tested images involve three main types of cracks: alligator, linear, and images without cracks. The testing results show that the developed model is capable of classifying cracks with an F1-score of 0.96, recall of 0.96, and precision of 0.96. In real-time detection of road cracks, the testing obtained an F1-score of 0.84, recall of 0.92, and precision of 0.77. This research contributes to the advancement of road crack detection technology by leveraging the capabilities of Wavelet and CNN, enhancing the accuracy and efficiency of crack detection in road maintenance.

Published: September 2024

This experimental investigation reveals the preparation of natural composite material from foxtail palm tree seeds. The fruits from the foxtail palm tree are used for the extraction of oil, and the by-product of the extraction process is freely dumped. This study attempts to utilize the waste by-product of foxtail palm tree fruit as a valuable natural composite material. The fabrication was done using the hand lay-up method for the proposed reinforcement (4% and 8%) of filler materials. The obtained composite materials are subjected to significant mechanical characterization of tensile behaviour, flexural property, and hardness. In addition, the morphological study was also carried out by the scanning electron microscope (SEM). The results show that, as the reinforcement percentages of filler material increase, the mechanical properties are improved. This may be due to the uniform dispersion of natural fibres in the polymer. The tensile strength was improved by 22.43% and 29.08% for 4% and 8% filler reinforcement. Similarly, the stiffness property was improved by 9.32% for 4% reinforcement and 18.68% for 8% reinforcement when compared with neat composite. The SEM images reveal the failure analysis, bonding strength and fibre pull-out in the composites. Finally, the foxtail fruit fibre shows promise as a reinforcing agent in composite materials, improving their mechanical properties and making them suitable for various applications requiring strength, stiffness, and resistance to deformation.

Installing rooftop Solar Power Plants (SPP) represents the most efficient solution for reducing substantial electricity consumption in office buildings and hospitals, as Makassar Eye Hospital exemplifies. The research commences by addressing concerns about electricity availability and daily usage at the hospital while evaluating the solar radiation potential. Subsequently, the development of the SPP system begins. A location assessment is conducted using various tools to gather the necessary data for SPP design. In this study, the planning phase involves the utilization of PVSyst software for the technical analysis of electrical energy generation and system performance calculations. Additionally, the economic analysis includes evaluating the initial investment costs for establishing the SPP and considering prevailing market prices for components. The feasibility of the SPP investment is determined by calculating key financial metrics, including the Payback Period (PP), Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI), and Return on Investment (ROI). According to the economic analysis findings, the initial investment cost for the SPP amounts to Rp. 544.031.733. The energy production value per kilowatt-hour (kWh) stands at Rp. 1.278, resulting in a Payback Period (PP) of 13,8 years, a Net Present Value (NPV) of Rp. 138.182.638, an Internal Rate of Return (IRR) of 11.51%, and a Return on Investment (ROI) of 25.4%. These results affirm the plan's feasibility, as the IRR value surpasses the Discount Rate (8.43%).
Blockchain-BIM: reducing cost in green retrofitting for sustainable construction development
Authors: Husin Albert Eddy , Kristiyanto Kristiyanto , Kussumardianadewi Bernadette Detty
Published: September 2024

During the implementation process, the construction sector significantly affects the environment, leading to environmental pollution and the overconsumption of natural resources. This jeopardizes the sustainability of a healthy living environment, requiring a solid system to control development. A sustainable and environmentally friendly development system is crucial from architectural, construction, and economic perspectives. However, when applying the concept of Green Building to existing buildings, the cost of green retrofits has increased by about 10.77%. A case study was carried out on the existing BRIN (National Research and Innovation Agency) building to provide alternative solutions to reduce these green retrofitting costs, making sustainable construction the primary option in developing the construction sector. One way to address this cost increase is using the Blockchain-Building Information Modeling (BIM) application, an alternative method to determine the most economical cost based on input or a given model. BIM models contain non-geometric information, including materials for building components, quantities, prices, procedures, scales, and sizes. This allows for real-time data exchange and collaborative decision-making between stakeholders, improving visualization and modeling and lowering costs due to better construction outcomes and higher productivity probability. The implementation of Blockchain-BIM is expected to result in green retrofit cost savings of at least 3% on each green level according to the Ministry of Public Works and Housing (PUPR) of the Republic of Indonesia Technical Guidelines No. 01/SE/M/2022, namely Primary, Intermediate, and Main.

In the last few years, much research has focused on the stability and improvement of the thermo-physical properties of single-component nanofluids. Some studies have not made many improvements to the stability and thermophysical properties of various types of green nanofluids from several variations of nanoparticles. Green nanofluids must be developed to improve heat transfer performance from their stability and thermal conductivity factors. Stability and thermal conductivity of Nano-silicate suspended in a base mixture of water /ethylene glycol with the ratio of 60:40, different volume concentrations were investigated. The experiments carried out were the stability of the green nanofluids investigated for volume concentrations of 0.1~0.3% and temperature conditions from 30 to 70°C for thermal conductivity measurement using TEMPOS Thermal Properties Analyzer. The experimental results showed that the stability analysis of the green nanofluids prepared by the UV-Vis method was stable up to 30 days after preparation with a sonication time of 1 hour with a ratio of 70-80%. The evaluation of the zeta potential for green nanofluids obtained a value of 33.57 mV with a moderate stability classification. The highest thermal conductivity for the green nanofluids was obtained at 0.3%, and the maximum increase was 17% higher than that of the base liquid (W/EG). Green nanofluids with a concentration of 0.1% gave the lowest effective thermal conductivity of 1.09 time at 70°C.

Published: September 2024

As a part of an area, residential real estate has various spatial configuration patterns, which are part of the elements that form its environment. Depending on the context of certain places, spatial configuration and security reinforcement become a concern regarding the issue of crime prevention, which promotes a safe neighbourhood that avoids the risk of crime. A phenomenon took place where there are several preventive actions were carried out at the basic stage of planning and designing residential real estate, but these efforts later brought various methods and priorities that determine spatial configuration or security reinforcement to serve either as the main reference or adjustment at the initial step. This research dissects the relationship between spatial configuration patterns and security systems applied using the Crime Prevention Through Environmental Design (CPTED) approach to obtain the most optimal solution in preventing crime and reducing crime rates. This research used descriptive analytical methods in a comparative way to derive the final synthesis of three residential real estates in Bintaro Jaya as study objects. The results of this research discovered the most conducive type of residential real estate in terms of its security level. These findings can enrich the development of studies on similar topics and contribute to the consideration of design criteria related to spatial configuration and security reinforcement of residential real estate in anticipating potential crimes.

The concept of digital farming can help farmers increase their agricultural production yield. One of the technologies to support digital farming is robotics, which can be utilized to complete a redundant task efficiently for 24 hours. This paper presents a simple and effective harvesting robot that is applied to harvest a ripe strawberry. The mechanical and electrical design is kept simple to ensure it is reproducible. The input from a proximity sensor and image detection by a Pi camera is utilized by FLC (Fuzzy Logic Controller) to improve the effectiveness of the harvesting task. The image processing method in this study is image segmentation, which fits with the limited source of the microcontroller available in the market. The experiment included 60 times (20 times center, left, and right position) harvesting using the FLC algorithm and 60 times without FLC to show the effectiveness of the proposed method. From 60 experiments without an FLC experiment, there is an 80% hit rate for strawberries positioned in the middle of an image plane and 55% for left and right strawberries. From 60 times of FLC experiment, 95% hit rate for strawberries positioned in the middle of an image plane, 80% for left and right strawberries. The average time required to finish the task without FLC for strawberries in the middle is 13.51 s, the left is 11.04 s, and the right is 17.28 s. While the average time required to finish the task with FLC for strawberry in the middle is 12.90 s, the left side is 11.71 s, and the right side is 10.93 s. This study is intended to show that simple designs can be helpful and affordable when applied to greenhouse farming in Indonesia.

Authors: Nahdatunnisa Nahdatunnisa , Tahir M. Arzal
Published: September 2024

An optimal pedestrian pathway should cater to various user needs, encompassing safety, comfort, and universal accessibility. This research endeavors to evaluate the efficacy of pedestrian pathways, with a particular focus on public green spaces in Kendari City. The study emphasizes the implementation of an inclusive design concept for pedestrian pathways, ensuring the protection and fulfillment of rights for all demographic groups. To achieve its objectives, the research employed both qualitative and quantitative methods. A qualitative case study approach was utilized to assess architectural elements, while a Likert scale was employed for the performance evaluation. The findings from the performance assessment indicate that the service attribute values fall short of being optimal. Observational data suggest that most existing facilities fail to adhere to universal design principles, catering to the needs of all individuals. Consequently, there is a pressing need for physical modifications in the pedestrian pathway areas. These modifications include the installation of ramps, clear markings, and pathways for people with disabilities (guiding blocks), as well as the integration of trees and plants, trash receptacles, traffic signs, and essential utilities such as street lighting and billboards. Furthermore, the research highlights the necessity of organizing street vendor (PKL) zones across all area segments to enhance overall accessibility and usability.
Pasternak and Severyanin: Two Editions of Vokzal
Authors:   National Research University Higher School of Economics (School of Philological Sciences), Levina Maria D.
Published: September 2024

Boris Pasternak’s early work, in particular, in the first two books of poems, Bliznets v tuchakh (Twin in the Clouds, 1914) and Poverkh bar’erov (Over the Barriers, 1916/1917), demonstrates the “traces” of Igor Severyanin’s (Igor Lotarev) style and imagery. However, in 1928, Pasternak significantly rewrote his early poems for a new book. The poet frees several poems from Severyanin’s influence but does not eliminate the elements of his older contemporary’s poetics and stylistic features. The present article shows the evolution of reminiscences from Severyanin’s texts in early and late editions of Pasternak’s Vokzal (Station, 1913, 1928). In the 1928 edition of Vokzal, Pasternak abandons some of Severyanin’s techniques presented in the 1913 edition in favor of “simplification.” Therefore, he moves away from the “artsy” vocabulary and Latin alphabet and, at the same time, adds colloquial words. Nevertheless, despite the emphasized transition to a new period in his work, Pasternak seems to retain some of his former style’s particular signs.
Estate as “A House at the Edge of Time” in Texts of English Children’s Writers of the 19th–21st Centuries
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Veligorsky George A.
Published: September 2024

Since the 19th century, British literature addressed to young readers begins to emerge an unusual image of the world, in which, without the intervention of a fantastic element and almost imperceptibly for the reader, different times and eras are harmoniously combined. The crucial technique for creating such a universe is an anachronism, skillfully used by the author and not exposed to him; the latter, in turn, can leave clues for an attentive reader ready to join his “game.” The image of such a space turns out to be consonant with ideas developed in literary studies in recent years, such as the concept of “mythical (nonlinear) time” (M. Nikolaeva), “closed world” (P. Hunt), “palimpsest world” (M. Certeau), etc. The most important locus of such a world in the texts we are considering (Water Babies by Ch. Kingsley, The Wind in the Willows by K. Grahame) turns out to be a noble estate, to denote which we propose to use the term we introduced — “house on the edge of time.” As an additional task, we will analyze the world of W. Maine’s novel Earthfasts (1966), a fantastic “borderland,” which, in our opinion, serves as a development of the image of the Vendale in the tale by Charles Kingsley.
Mass Carbon Monoxide Poisoning on a Train in Italy, March 1944. History Reconstructed
Authors:   Emeritus Physician, Virginia Mason Medical Center, Seattle, WA, Hampson, MD Neil B.
Published: September 2024

World War II was approaching its end in Italy in 1944 when one of the worst train disasters in world history occurred near the small town of Balvano in the Apennine Mountains. The train did not derail or crash into something as in most major train disasters. Instead, it entered a mountainous railway tunnel, and when it emerged, over 500 passengers were dead from carbon monoxide poisoning. The event was not allowed to be publicized for almost two decades. This manuscript reconstructs the story of possibly the most significant incident of carbon monoxide mortality ever recorded.

Published: September 2024

Understanding codon usage has been vital for optimizing biotechnological
applications across various domains. In response to this necessity, this
review examines the impact of codon usage on protein expression systems,
highlighting strategies to enhance yield and solubility in prokaryotic
and eukaryotic hosts. We have discussed the role of codon usage in
vaccine development, emphasizing how tailored codon sequences improve
antigen expression and immune responses. In therapeutic protein
production, optimizing codon preferences is shown to increase yields and
reduce misfolding, facilitating the cost-effective manufacture of
complex proteins. The review further explores the significance of codon
usage in gene therapy, metabolic engineering, and synthetic biology,
where precise codon design can drive innovations in genetic circuits and
metabolic pathways. Additionally, we addressed emerging technologies and
methodologies that enhance our understanding of codon optimization,
paving the way for future advancements in biotechnology. By integrating
insights from most recent studies, this paper underscores the importance
of codon usage and its optimization, highlighting its transformative
potential in enhancing the efficacy and scalability of biotechnological
processes. Overall, we propose future directions for research,
advocating for a multidisciplinary approach that combines computational
tools and experimental validation to unlock the full potential of codon
usage in biotechnology.
A Randomized, Noninferiority, Comparative Evaluation of Vascular Securement Devices: Cost and Clinical Analysis
Authors: Simmons Colby G. , Williams Jason D. , Kheirandish Azin , Kaizer Alexander M. , Brainard Jason C.
Published: September 2024

Highlights

Background:

Peripheral intravenous catheters (PIVCs) are a near universal element of modern medicine with nearly 2 billion PIVCs placed annually worldwide. Virtually all PIVC complications are related to stabilization. Recent innovations in dressings and securement have sought to minimize these complications; however, evidence is lacking in determining superiority of devices and selecting one product over another. In this quality assurance evaluation, we attempted to select a more cost-effective and optimal product for use in our large, tertiary-referral academic institution.

Methods:

A randomized, noninferiority, comparative evaluation was undertaken to compare an integrated securement device (ISD) new to our institution to our institution’s current standard adhesive securement device (ASD). Patients were selected for randomization based on likelihood of a >5-day postoperative inpatient stay, allowing for prolonged daily follow up and survey of both patients and nurses.

Results:

Results showed that the ISD outperformed the ASD in terms of efficiency of application, adhesive quality, stability, overall satisfaction, and patient comfort. Additionally, the ISD demonstrated a lower rate of complications than the ASD. Cost analysis revealed that the ISD was 28% less expensive than the ASD, resulting in significant cost savings and fewer venipunctures.

Conclusion:

Intravenous catheter placement is the most common procedure performed annually in hospitalized patients. Given the large volume of PIVC insertions each year and associated costs, combined with the frequency of complications, it is imperative to identify a more adequate and cost-effective device. Our quality improvement project, at a high-volume, tertiary care referral center, provides the groundwork for similar studies at other institutions and supports a more cost-effective and potentially safe delivery.

Background. The significance of the problem of treatment of acute pancreatitis is due to an increase in the incidence with an increase in the number of necrotizing forms, accompanied by a high incidence of severe complications and high mortality.

Objective. To identify the impact of regionally used extracellular microvesicles of mesenchymal stromal cells on the endogenous intoxication markers in acute necrotizing pancreatitis in the experiment.

Material and methods. Acute pancreatitis was induced by the introduction of a 0.3 ml of 5% solution of non-ionic polyethylene glycol octylphenol ether detergent into the caudal part of the rat pancreas. The study was conducted on 42 adult Wistar rats, which were randomly divided into 4 groups. Group I (n=6) included intact animals, Group II (control group) (n=12) included rats with pancreatitis without treatment, Group III (n=12) consisted of rats with pancreatitis treated with analgesia + infusions of 0.9% sodium chloride solution (saline), Group IV (n=12) included rats with pancreatitis treated with analgesia+ saline infusions + regional application of extracellular microvesicles of mesenchymal stromal cells. Cells were obtained from the bone marrow of healthy animals. Microvesicles were obtained by differential centrifugation under sterile conditions. Microvesicles were administered one day after the pancreatitis induction through the catheter installed into the pathologically altered part of the pancreas. The dose of microvesicles was calculated as equivalent to (derived from) 1 million mesenchymal stromal cells. The hematological parameters, markers of the systemic manifestation of the pathological process (alpha-amylase, aspartate aminotransferase, alanine aminotransferase), the endogenous intoxication markers (lipid peroxidation activity, nitric oxide level), the systemic inflammatory response markers (tumor necrosis factor-alpha, interleukin-6) were studied on the 3rd and 7th day from the start of disease modeling.

Results. Regional use of extracellular microvesicles of mesenchymal stromal cells in the treatment of acute experimental necrotizing pancreatitis at an early stage helped to normalize the level of blood platelets, reduce enzymeemia, elements of endogenous intoxication (interleukin-6, tumor necrosis factor-alpha), and the nitric oxide level.

Conclusion. The early application of extracellular microvesicles of mesenchymal stromal cells in the treatment of acute necrotizing pancreatitis in an experiment has a positive effect on parameters, which are key links of pathogenesis and leading markers of this disease severity.

Background. The number of heart transplant patients makes 1 per 100,000 in the Russian Federation, 1.2 per 100,000 population in the Tambov Region. The medical community is poorly informed about the specific features of managing such patients during non-cardiac surgical interventions. The article presents a case report of the management of a patient with a transplanted heart undergoing surgery for acute appendicitis. Preoperative preparation, anesthesia management, surgery, and postoperative care and rehabilitation were provided taking into account the presence of a transplanted heart in the patient, according to the Guidelines developed by the experts of the V.I. Shumakov Federal Research Center of Transplantology and Artificial Organs where the heart transplant had been performed to the patient, and standard clinical recommendations.

Case Report. An 18-year-old patient diagnosed with acute phlegmonous appendicitis with a heart transplanted in 2021 for dilated cardiomyopathy underwent laparoscopic appendectomy 3 years after heart transplantation. Anesthesia was provided taking into account the presence of a denervated donor heart, a high risk of myocardial ischemia and heart ailure (low cardiac output syndrome), and the need for a timely correction of hypovolemia and hypotension. Anesthesia management was a general combined multicomponent anesthesia.

Conclusion. This clinical case has shown the possibility of providing medical care to a patient with a transplanted heart at a modern level in an urban multidisciplinary hospital. Non-cardiac surgery was performed in accordance with recommendations of specialists of V.I. Shumakov Federal Research Center of Transplantology and Artificial Organs and clinical recommendations in order to achieve optimal results and the fastest possible rehabilitation in the postoperative period.

Background. Unexpected transmission of an infectious disease agent with a kidney graft to a recipient is a rare event but it is associated with significant morbidity and mortality, especially when exposed to multidrug-resistant bacteria that have not been eliminated by standard antibiotic prophylaxis.

Objective. To demonstrate the need for immediate removal of a primary infected kidney graft in the event of local purulent complications due to the rapid development of sepsis in immunocompromised patients.

Results. The paper describes a clinical course of the infectious process in two kidney recipients each of whom underwent transplantation of a primary infected graft from a single donor, taking into consideration the transplantectomy timing and the treatment outcomes.

Conclusion. The Case Report shows the need for immediate transplantectomy in a kidney graft recipient when local purulent complications are detected with confirmed primary infection of the graft due to a high risk of the rapid development of sepsis and threat to life.
Robotic surgery in the aspect of liver transplantation

Introduction. Almost 60 years have passed since the first liver transplant performed by Thomas Starzl. During this time, medical technologies have gradually improved, which has made it possible to use more and more new methods and approaches in this type of medical care. One of the new techniques of recent decades is robotic surgery, which is gradually being introduced into medical practice, including in the field of transplant medicine.

Objective. The purpose of writing this review was to summarize knowledge and describe the current status of development of robotic surgery in the aspect of liver transplantation, namely: liver resection in donors, as well as graft implantation in the recipient.

Material and methods. The review includes foreign and domestic publications on minimally invasive donor liver surgery. Publications on the topic of robotic liver resection in the aspect of liver transplantation were also processed.

Conclusion. Robotic surgery using advanced robotic systems represents the next step in the development of minimally invasive technologies in liver transplantation. Robotic systems provide more precise and dexterous control of instruments, allowing surgeons to perform complex procedures with greater precision and less risk to patients. However, the robotic approach is still very limited in geographical distribution and requires much more experience than laparoscopy. The upcoming introduction of new robotic systems that support haptic feedback or cavitronic ultrasonic surgical aspirators will further promote a widespread adoption of robotic liver resection in liver donors and liver recipients.
