Published: August 2024

Abstract
The need to create resource-saving technologies of building materials using closed-loop production (CLP) has been analyzed. The features of the use of waste in the production of ceramic tiles, their influence on the properties of materials and possible limitations have been determined. The composition of the ceramic mass with the use of waste from the enrichment of quartz-feldspar raw materials of «Maydan-Vilsky Quarry» LLC has been developed. The results of the study of the chemical composition of KRM-12 established that the composition of its residue is characterized by a high content of silicon and potassium oxides, which allows us to conclude about a significant content of pegmatite. The chemical composition of the residue QRM-12 is characterized by an increased content of aluminum and potassium oxides, which indicates the presence of dispersed kaolin and pegmatite crystals. A feature of QRM-12 is increased plasticity – 9 units. The influence of the proposed composition on the characteristics of finished products is determined. Interpretation of the «mullite–silica–leucite» phase diagram showed that crystallization and grain growth are closely related to the amount and viscosity of the liquid phase present at the firing temperature. The technological and economic feasibility of using pegmatite enrichment waste in the production of competitive building materials is shown.

Abstract
The article discusses the possibilities of planning and managing processes of normalization of urban airspace using the example of pollution with nitrogen oxides and PM2.5 particles. An assessment of the level of air pollution in a large city using the example of Kyiv revealed a significant amount of nitrogen oxides along the main roads, and even the presence of green spaces does not save the situation. Due to differences in access to fresh air, different areas of the city develop their own microclimates with elevated temperatures and pollutant content. Such “hot areas” must be identified and declared hazardous to human habitation. It is noted that the largest amount of air is required to dilute the exhaust gases of diesel cars, where there is a large emission of soot, and carburetor cars, where there is a large emission of carbon monoxide. For almost all types of transport, the presence of nitrogen oxides is observed in emissions, which require a significantly larger amount of atmospheric air for dilution, with a difference of two times and an order of magnitude compared to carbon oxides and soot. Green spaces must occupy large areas to have a significant impact on the environment. Improving ecosystem services for air purification and climate regulation requires not only planning urban green spaces as a comprehensive solution, but also special air purification devices.
Comparative analysis of Ukrainian and international standards in the context of mining tailings dam design requirements
Authors: Radchuk O 
Published: August 2024

Abstract
The global global mining industry produces billions of tonnes of mine tailings each year. These tailings are typically a mix of finely ground rock, chemicals in the extraction process, and water. Tailings are commonly stored in Tailings Storage Facilities (TSFs). TSFs are dynamic structures that are designed and managed to contain the tailings produced by mining operations. The construction of industrial tailings storage facilities has become widespread at the current stage of development of the mining industry in Ukraine and abroad. The focus is primarily on ensuring the reliability and safety of these facilities during their design, construction, and operation, as a failure of such structures can have catastrophic consequences. This paper presents a review and a comparative analysis of the requirements of Ukrainian standards with international standards in the design of tailings storage facilities. Comparing Ukrainian and international standards in the context of tailings design requirements can provide insights into the similarities and differences in their approaches. Ukraine has specific regulations and guidelines for tailings design, which could differ from international standards. It is important to analyze how Ukrainian standards align with international best practices.
An energy expenditure approach in mass transit commuting choice preferences
Authors: Ponkratov Denys , Kopytkov Denys , Galkin Andrii , Samchuk Ganna , Davidich Yuri 
Published: August 2024

Abstract
Current urban development should not be possible without public transportation. Adequate mass transportation can only be ensured by disclosing a stable commuter’s travel distribution along routes. Due to this, urban transportation improvement via applying the sustainable transport principles such as free access and path choice and minimizing the use of various types of energy is a major challenge. In this case, special attention is paid to working trips, which constitute the largest burden on urban transport and have dense directions in a short time. As with any actions, public journeys are closely taken to human energy expenditure, which is further increased when passengers then have to perform their main workplace tasks. Thus, a public transport trip can be seen as the start of a working day. Consequently, mass transport systems should therefore be presented in a way that minimizes energy consumption by passengers. This can be found by establishing an interrelation between travel energy consumption and travel choice and, this way, explaining the attractiveness of stable route options. The attractiveness obtained should enable the travel choice probabilities to be calculated and the urban mass transit system to be better organized in satisfying the needs of users.
Risk factor assessment in agricultural supply chain by fuzzy logic
Authors: Muzylyov Dmitriy , Medvediev Ievgen , Pavlenko Olexiy 
Published: August 2024

Abstract
Significant uncertainty characterizes the harvest period. This aspect is due to various risks impacting agrifood supply chains. The occurrence of risks is due to hazards: technological failures, technical breakdowns, or adverse weather conditions. Hence, the operational time of the agricultural supply chain during the harvest period increases due to such risk factors. In essence, some hazards are fuzzy, and the nature of most threats is characterized by significant uncertainty. Classical risk assessment methods do not allow assessing simultaneously the impact of various risks, especially those expressed fuzzy (weather conditions). Therefore, the study objective is to design a fuzzy model assessing risk factors that impact the increase in the operating time of the agrifood supply chain during the harvest period. As initial parameters in the indistinct model, three groups of risk factors were accepted: weather conditions, technological failures and technical malfunctions. The MATLAB Fuzzy Toolbox is used to design the fuzzy model, and the model architecture is implemented in Simulink. The modelling results can be used to create the necessary reserves of the harvesting and transport complex to ensure timely harvesting and reduce the negative impact of hazards on the agricultural supply chain operating.

Published: August 2024

Abstract
Human resources research is always relevant, as their development is almost continuous. This work is dedicated to addressing issues related to the assessment, development, and strengthening of the human component of productive forces. A particular emphasis is placed on population replenishment through re-emigration. However, such programs have a nationwide scope and do not take into account the difficulties that regional leaders encounter when implementing such programs locally. Regions that receive migrants often face challenges such as housing shortages, limited space in childcare facilities and schools, and the potential strain on public transportation, as well as overloaded government services, and more. This occurs precisely because there is no forecasting of changes in the volume and structure of human resources, even in the short term. In the context of geopolitical transformations, making long-term predictions is not advantageous. Therefore, a simplified system for assessing the development of human resources, which, unlike others, considers the intensity of human resource outflows and migration processes, becomes relevant. This is why the purpose of this work is to create a mathematical model that will allow for the evaluation and prediction of the development of human resources. To achieve this goal, the author has decided on several tasks: building a mathematical model for evaluating the development of human resources, taking into account immigration and re-emigration growth, and developing coefficients for assessing the implementation of re-emigration stimulation programs.
Host–bacteria interactions: ecological and evolutionary insights from ancient, professional endosymbionts
Authors: Bontemps Zélia , Paranjape Kiran , Guy Lionel 
Published: August 2024

Abstract
Interactions between eukaryotic hosts and their bacterial symbionts drive key ecological and evolutionary processes, from regulating ecosystems to the evolution of complex molecular machines and processes. Over time, endosymbionts generally evolve reduced genomes, and their relationship with their host tends to stabilize. However, host–bacteria relationships may be heavily influenced by environmental changes. Here, we review these effects on one of the most ancient and diverse endosymbiotic groups, formed by—among others—Legionellales, Francisellaceae, and Piscirickettsiaceae. This group is referred to as Deep-branching Intracellular Gammaproteobacteria (DIG), whose last common ancestor presumably emerged about 2 Ga ago. We show that DIGs are globally distributed, but generally at very low abundance, and are mainly identified in aquatic biomes. Most DIGs harbour a type IVB secretion system, critical for host-adaptation, but its structure and composition vary. Finally, we review the different types of microbial interactions that can occur in diverse environments, with direct or indirect effects on DIG populations. The increased use of omics technologies on environmental samples will allow a better understanding of host–bacterial interactions and help unravel the definition of DIGs as a group from an ecological, molecular, and evolutionary perspective.
The Wuhan Alarm
Authors: Yang Dali L. 
Published: August 2024

Abstract
This chapter reviews the initial response to the emergence of COVID-19 cases in Wuhan, highlighting the contributions of clinicians, independent clinical laboratories, and hospital administrators. Contrary to popular belief, several clinicians, including Dr. Zhang Jixian, reported the early instances of pneumonia of uncertain etiology to local CDCs. Commercial diagnostic labs, notably Vision Medicals, played a pivotal role in identifying the causative pathogen as a SARS-like novel coronavirus. The chapter gives special emphasis to “Patient A,” whose inter-hospital transfer facilitated the dissemination of crucial disease information. It also reveals the non-utilization of the National Notifiable Disease Surveillance System for reporting these cases, which had significant implications for responding to the outbreak. Additionally, this chapter scrutinizes an unpublished joint investigation report that had a substantial impact on the official response to the epidemic.
The Decision to Seal Off Wuhan
Authors: Yang Dali L. 
Published: August 2024

Abstract
This chapter explores key events leading to the historic lockdown of Wuhan, a city of over 10 million people. It starts with the pivotal visit of the Senior Advisory Panel, led by Dr. Zhong Nanshan, on January 19, 2020, which confirmed extensive medical staff infections in Wuhan. It then discusses the State Council Executive Meeting on January 20, which recognized novel coronavirus pneumonia as a new infectious disease. Faced with escalating cases and insufficient response from Wuhan and Hubei authorities, Chinese leader Xi Jinping intervened, leading to the enforcement of a cordon sanitaire on January 23. The chapter emphasizes the strategic decision by China’s national health leadership to use experts like Dr. Zhong Nanshan to communicate the epidemic’s severity and enforce containment measures. It also elucidates how the Wuhan lockdown aimed to avert an immediate World Health Organization declaration of a public health emergency of international concern.
The Real Wuhan Lockdown
Authors: Yang Dali L. 
Published: August 2024

Abstract
This chapter delves into the critical role of community-level measures during the Wuhan lockdown. Contrary to popular perception, the initial phase of the lockdown was not strictly implemented as communities experienced chaos and difficulties. However, in February 2020, a shift in approach occurred when Xi Jinping and the national leadership replaced the top leaders in Wuhan and Hubei, redirecting the battle against the virus toward community engagement. The grassroots governance structure, as part of the Communist Party–led system, became instrumental in enforcing stringent home confinement rules and curtailing virus transmission concurrent with substantial improvements in hospital and quarantine capacities. Despite the challenges in execution, these measures found widespread acceptance within Chinese society, facilitated by a pervasive fear of the virus, advanced digital communication networks, and efficient supply chain logistics. Many of these strategies were adopted in other cities during China’s pursuit of the zero-COVID strategy.
Was the COVID-19 Pandemic Inevitable?
Authors: Yang Dali L. 
Published: August 2024

Abstract
This concluding chapter posits the complexities of the COVID-19 pandemic as a “wicked problem,” challenging existing governance frameworks and notions of regime type and governance quality. It notes that effective governance in responding to the pandemic necessitates rapid adaptation to evolving knowledge about the virus, advances in technology, and maintaining public trust. This chapter highlights two inter-related aspects of China’s outbreak response that undermined effectiveness. First are the fissures and tensions of fragmented authoritarianism in the Chinese party-state that prioritized stability and information control. Second was the weakness in strategic leadership during the early weeks of the outbreak. Noting China’s extraordinary capabilities evident in containing the virus post-lockdown, the final section considers the thought experiment of whether the COVID-19 pandemic could have been prevented had China had a transparent and open information environment.
Impact of Gender-confirming Chest Surgery on Sexual Health: A Prospective Study
Authors: de Schoulepnikoff Camille , Bauquis Olivier , di Summa Pietro G. 
Published: August 2024

Background:
Few studies have evaluated the improvement of the sexual well-being of transgender patients after breast augmentation or bilateral mastectomy. This prospective study aims to assess the potential improvement in body awareness during sexual intercourse, as well as the nipple-areolar complex (NAC) sensitivity recovery after gender-confirming chest surgery.

Methods:
From October 2019 up to April 2021, all transgender patients eligible for gender-confirming chest surgery in our institution were asked to fill out two questionnaires, namely BREAST-Q (a patient-reported outcome measure for use in reconstructive breast surgery and clinical practice) and Body Exposure during Sexual Activities Questionnaire (scientifically validated self-report assessments of body-image experiences in the context of sexual relations). The Semmes-Weinstein monofilament test was used to evaluate NAC sensitivity recovery. Different follow-ups were considered: preoperative and 4 and 12 months postoperative.

Results:
Twenty-one transmasculine and 12 transfeminine patients met the inclusion criteria. For both groups, the preliminary 4-month postoperative evaluations showed significant improvement in psychological well-being and chest/breast satisfaction compared with preoperative values. Body awareness during sexual intercourse improved significantly at 4 months postoperative in the transmasculine groups (P ≤ 0.001) and at 12 months postoperative in the transfeminine group (P ≤ 0.01). No correlation between body awareness during sexual intercourse and NAC sensitivity was observed among either group, transmasculine and transfeminine patients.

Conclusions:
Although aesthetic and psychological well-being increased quickly postoperatively, sexual health remained low among transfeminine patients until they completed their transition with vaginoplasty. NAC sensitivity recovery was found to not contribute to the improvement of the sexual health of transgender patients.
Multilayered Silver-containing Polyurethane-foam (Mepilex Ag) for Tie-over Bolster Fixation of a Skin Graft
Authors: Saijo Yusaku , Cho Hoyu , Mitsuwa Hideyuki , Ogawa Rei 
Published: August 2024

Summary:
Tie-over bolster fixation is the most common method of securing a skin graft. The bolster material can consist of various materials, including sterilized polyurethane foam. Mepilex Ag is a silver-containing polyurethane-foam wound-dressing material that has a broad-spectrum antibiotic effect. The use of a silver-containing polyurethane foam as bolster material in tie-over bolster fixation has not been reported previously. We report here our method of a multilayered silver-containing polyurethane-foam tie-over bolster fixation and its outcomes when used during reconstruction of a relatively small skin defect on the nasal dorsum with a full-thickness skin graft. The skin graft was completely viable, and there were no complications such as infection, hematoma, or necrosis.
Exosome-mediated Advancements in Plastic Surgery: Navigating Therapeutic Potential in Skin Rejuvenation and Wound Healing
Authors: Park Soo Yeon , Yi Kyu-Ho 
Published: August 2024

Summary:
Exosomes, tiny extracellular vesicles derived from various cells such as adipose-derived stem cells, bone marrow-derived mesenchymal stem cells, and human umbilical cord mesenchymal stem cells, exhibit considerable potential in wound healing due to their ability to facilitate cell communication and modulate inflammatory responses. These exosomes contribute positively to collagen synthesis and scar reduction, and have shown efficacy in documented clinical cases of wound improvement. Although research indicates their potential in reducing hypertrophic scars and suppressing keloid fibroblasts, further clinical investigations are warranted. In plastic surgery, exosome application postsurgery can enhance wound healing, particularly in cases prone to swelling or poor healing conditions. This study incorporates five case reports of individuals undergoing exosome treatment (EXOP; Sihler Inc., and Exodew; Hyundaimeditech, Inc.) for wound healing, providing practical insights into the application of this therapeutic approach. The five case reports presented in this study demonstrate the practical applications and efficacy of exosome therapy in promoting wound healing and reducing scarring. Exosomes emerge as a promising avenue within the field of plastic surgery, showcasing their potential to enhance wound healing, reduce scarring, and improve overall outcomes in clinical settings. The findings from this study underscore the importance of further exploration into the therapeutic benefits of exosomes in wound management, paving the way for their widespread adoption in clinical practice.

Authors: Demetri Leah R.F. , Chung Kevin C. , Blazar Philip E. 
Published: August 2024

SUMMARY:
Rheumatoid arthritis (RA) is a common inflammatory condition that can lead to debilitating hand and wrist deformity. Since the introduction of disease-modifying antirheumatic drugs in the 1990s, the rate of surgery for rheumatoid arthritis has dramatically decreased 1. Nonetheless, surgical intervention remains an important tool in the management of patients with RA, and young surgeons must seek out expertise in this domain due to diminished exposure during their training. In this article, we provide a comprehensive review of the evaluation and management of patients with wrist pathology due to RA as well as surgical technical pearls.

Published: August 2024

Abstract
Primary prostatic stromal sarcoma is extremely rare. Serum PSA is usually normal. Here, we report a case of primary prostatic stromal sarcoma in a 23-year-old man. 18F–prostate-specific membrane antigen (PSMA) PET/CT showed prostate mass and multiple low-density lesions in the liver with high PSMA expression. However, after chemotherapy, the level of PSMA expression in the prostate mass decreased, and PSMA expression lesions in the liver disappeared.

Abstract
We report a case of a 48-year-old man with recurrent hepatocellular carcinoma, who underwent FDG PET for restaging and demonstrated mildly tracer-avid arterial enhancing lesion in segment III (SUVmax, 5.7). Owing to low FDG uptake, patient was planned for 68Ga-SA.FAPi PET, which demonstrated higher tracer avidity in the lesion (SUVmax, 24.4). Subsequently, patient underwent 177Lu-microsphere SIRT (2.2 GBq) in segment III. The 3- and 6-month posttherapy SA.FAPi PET demonstrated an interval decrease in tracer uptake and size of treated lesion. This case highlighted the promising role of SA.FAPi PET in patient selection for 177Lu-SIRT and subsequent response assessment.
