Response of date palm offshoots (Phoenix dactylifera L.) to the foliar spray of salicylic acid and citric acid under salinity conditions
Authors: Shareef Hussein J. , Abbas Muayed F. , Jasim Abbas M.
Published: August 2022

Antioxidants enhance the salt tolerance of date palms. A field experiment was carried out on date palm offshoots to improve the salt tolerance of the Sayer cultivar. Salicylic acid and citric acid (500 and 1,000 ppm) were used. The results showed that all growth parameters of plant height, leaf area, and leaf numbers decreased under the salinity conditions. The antioxidant applications increased the plant height, leaf area, carbohydrates, and relative water content compared with the control. Citric acid at 1,000 ppm decreased electrolyte leakage and malondialdehyde. Indoleacetic acid decreased, whereas abscisic acid increased under salinity. The antioxidant application increased indoleacetic, whereas abscisic acid decreased. Proline, protein content, and peroxidase activity increased under antioxidants. Also, the potassium and K/Na ratio increased under antioxidant applications. Citric acid improved the characteristics more than salicylic acid, encouraging farmers to use it for its low cost as an antioxidant to reduce environmental stress damage.

The aim of the study was to assess the current state and productivity of black alder (Alnus glutinosa (L.) Gaertn.) stands and determine the optimal conditions for the emergence and further growth of its natural regeneration in Ukrainian Polissya. The area of black alder stands in Ukrainian Polissya (Ukrainian forest zone) is 162,348 ha, reaching 8.4% of the total forest area. Volyn Region has the largest area of alder stands within Ukrainian Polissya (61,271 ha covering 37.7% of the total area). In the forests of this region, a more detailed study of the current condition, productivity, growth and regeneration of alder stands was performed. The natural regeneration under the alder canopy was characterized as poor. The largest numbers of alder seedlings (1,600–1,800 stems per ha) were recorded under the canopy of 76–78-year-old stands with a relative density of stocking of 0.63–0.70 and 80–100% of alder in their composition. Naturally regenerating alder seedlings had mainly group distribution on the area (occurrence is up to 40%). These specificities should be taken into account to promote natural seed regeneration of alder stands.

Published: August 2022

This study aimed at clarifying species composition and ecological structure of the ground beetles associated with oilseed rape fields during flowering, ripening and post-harvest, as well as pastures adjacent to them. Field work was carried out in 2017. Pitfall traps (5 in each site) were set in 20 sampling sites in the Transylvania region, Cluj County. A total of 8,151 individuals were collected (7,576 in rapeseed fields and 575 in pastures) belonging to 82 species from 29 genera. The richest tribes were Harpalini (25 species), Zabrini (12 species), Pterostichini (10 species), and Carabini (9 species). The most species-rich were the genera Harpalus (13 species), Amara (11 species), Carabus and Ophonus (8 species each). The most abundant species in the rape fields were Poecilus cupreus (1,760 ind.), Brachinus explodens (1,500 ind.), Brachinus elegans (1206 ind.), and Anchomenus dorsalis (875 ind.). The most abundant in the grasslands were Pterostichus hungaricus (101 ind.), Calathus fuscipes (74 ind.), Harpalus caspius (67 ind.), and Cylindera germanica (64 ind.). The species found only in rape fields were 36 while 13 species were exclusive to pastures; 34 species were discovered in both types of habitats. The investigation acquired some new data on carabid diversity in Romania, including two new country records.

Published: August 2022

In aircraft construction, when creating samples of new equipment, shock tests are often performed, both on individual components and the entire product. It requires introducing non-destructive testing devices into production, it is one of the most important factors in accelerating scientific and technological progress, raising the quality and competitiveness of manufactured products. Applying modern means of non-destructive testing, there is the problem of their protection from external vibrations, which affect the sensitivity, accuracy and reliability of high-precision measurements. In such cases, the conversion of measuring information during powerful vibration and shock tests, as a rule, is carried out by piezoelectric acceleration sensors. Although to provide impact testing, there is a need to develop and use stand-alone recorders. The main requirements for these recorders are to ensure the autonomy and operability of the recorder onboard the test product and to ensure the synchronization of the registration of the shock load.
Automatic Detection of Chip Pin Defect in Semiconductor Assembly Using Vision Measurement
Authors: Lu Shengfang , Zhang Jian , Hao Fei , Jiao Liangbao
Published: August 2022

With the development of semiconductor assembly technology, the continuous requirement for the improvement of chip quality caused an increasing pressure on the assembly manufacturing process. The defects of chip pin had been mostly verified by manual inspection, which has low efficiency, high cost, and low reliability. In this paper, we propose a vision measurement method to detect the chip pin defects, such as the pin warping and collapse that heavily influence the quality of chip assembly. This task is performed by extracting the corner feature of the chip pins, computing the corresponding point pairs in the binocular sequence images, and reconstructing the target features of the chip. In the corner feature step, the corner detection of the pins using the gradient correlation matrices (GCM), and the feature point extraction of the chip package body surface using the crossing points of the fitting lines are introduced, respectively. After obtaining the corresponding point pairs, the feature points are utilized to reconstruct the three dimensional (3D) coordinate information in the binocular vision measurement system, and the key geometry dimension of the pins is computed, which reflects whether the quality of the chip pins is up to the standard. The proposed method is evaluated on the chip data, and the effectiveness is also verified by the comparison experiments.
Evaluating an Inland Waterway Cargo Vessel’s Energy Efficiency Indices
Authors: Kalajdžić Milan , Vasilev Matija , Momčilović Nikola
Published: August 2022

Although the International Maritime Organization (IMO) introduced the energy efficiency requirements for ships more than a decade ago, to date, inland navigation has not been affected by corresponding regulations at all. Therefore, inland waterway vessels are left with no mandatory requirements that could push their technology into more energy efficient design. Fortunately, there are certain pioneering attempts to define energy efficiency criteria for inland vessels. This paper tries to gather and provide a review of such methods. Moreover, a typical Danube cargo inland vessel’s data are used to evaluate their current energy efficiency levels with respect to provisional criteria. Consequently, two methods are found and used here. They are both based on IMO’s energy efficiency concept but modified for the inland waterway vessels. The methods delivered a significant difference in applicability and were difficult to compare. Moreover, shallow and deep-water effects are explored in the same regard but provided unsound conclusions. The final results displayed discrepancies in energy efficiency levels for the same vessels and so the methodology should be improved and harmonised, if it is to be introduced as mandatory for inland waterway vessels. The analysis provided a glimpse into the current condition of the traditional design of the Danube inland fleet, with respect to the emerging energy efficiency policies.

Authors: MUȘETESCU Radu-Cristian , GRIGORE George-Eduard , NICOLAE Simona
Published: August 2022

Today, oil is one of the most popular commodities traded globally, due to its indispensable character and multiple properties offered to mankind. Increased attention is paid to the analysis of volatile and fluctuating trends in the overall price of this valuable energy source. Using the autoregressive conditional heteroskedasticity models such as GARCH(1,1), GARCH-M(1,1) and EGARCH(1,1), the present study has as a priority objective in estimating and predicting the volatility of the oil returns series (Brent Crude Oil return series) in the 1987-2022. The main results highlighted the preference in using the asymmetric model EGARCH (1,1) on the measurement of conditional variance, showing that Brent Crude Oil reacts over 90% to any existing market’s shock (i.e.: information, events, facts, news, etc.) in a negative manner/way. At the same time, various tests and evaluation conditions were used (ARCH-LM Test, Durbin-Waston Test, High Log likelihood, Lowest Schwarz Information Criteria) in investigating the level of performance in estimation the conditional crude oil volatility. Each GARCH (1,1) model is meeting brilliantly these conditions and acquiring the character of stability and validity in use. At the same time, performing forecast analysis on crude oil volatility in two different time periods: 1987-2022, respectively 2020-2022, it was shown that existence of the phenomenon of clustering-volatility over the time, with strong implications for the functioning mechanism of international financial markets. Fulfilling those restrictive conditions, the symmetric and parametric model GARCH-M (1,1) becomes, in our case, the most efficient model in forecasting the volatility of Brent Crude Oil return series in the analysed period.
Bitcoin is so Last Decade – How Decentralized Finance (DeFi) could Shape the Digital Economy
Authors: MNOHOGHITNEI Irina , HOROBEȚ Alexandra , BELAȘCU Lucian
Published: August 2022

Ever since the Global Financial Crisis, the financial system has seen an accelerated level of innovation. Bitcoin offered a decentralized alternative to money, with thousands of other cryptoassets quickly emerging. Most recently, Decentralized Finance (DeFi) promises to offer a new digital economy, with smart contracts replacing the need for financial intermediaries. This new market aims to reinvent traditional financial products in a more transparent and interoperable way. In this paper we aim to undertake an extensive literature review of the financial stability risks posed by the fast-growing DeFi market and assess these using the Financial Stability Board’s fintech framework. We find that DeFi could pose several challenges to traditional financial infrastructure, primarily by increasing interlinkages between cryptoassets and traditional financial markets. However, if DeFi evolves in a safe way, it could increase competition and financial inclusion with overall positive implications for financial stability.
Parapsychology and Transpersonal Psychology in Dialogue: Could These Two Movements Be Brought into Better Alignment?
Authors: Friedman Harris L. , Radin Dean , Krippner Stanley
Published: August 2022

Parapsychology and transpersonal psychology were founded independently and have evolved separately as two distinct movements, although there is considerable overlap in both their content and in the interests of a number of scholars who are active in both areas. Harris Friedman, Co-President of the Association of Transpersonal Psychology, and Dean Radin, President of the Parapsychological Association, engaged in an informal discussion on the salient commonalities and differences between the two movements, focusing on exploring ways that the two could be brought into better alignment, such as including more transpersonal approaches within parapsychological studies and vice versa. Stanley Krippner, whose seminal work straddles both areas, chaired the panel, introducing and serving as a discussant for Friedman’s and Radin’s views, as well as in presenting his own views on the relationship between parapsychology and transpersonal psychology.

Published: August 2022

85 adult residents of the Yamalo-Nenets Autonomous Okrug were examined: group 1 - 38 natives, group 2 - 47 newcomers (33.4±5.7 years). Using the ASPON-nutrition program, we studied the intake of vitamins A, E, D and C with food for 3 days. A significantly better supply of dietary rations of natives with vitamins E (p=0.012) and D (p=0.006) was established against the background of a significantly worse intake of vitamins A (p=0.015) and C (p=0.047) compared with newcomers. This can be explained by the insufficient consumption of dairy products, vegetables, fruits and greens by the indigenous inhabitants of the Yamalo-Nenets Autonomous Okrug, combined with a large intake of fish and deer meat.

Development of Course Booking System (Front-end & Back-end) Based on Mobile Application to Help Tutoring Elementary and Junior High School in Indonesia
Authors: Febrianti Elsa
Published: August 2022

Tutoring is informal education to help students who have problems outside of school. Students are helped to adjust to their learning situation so that they can develop efficiently according to their abilities. In Indonesia, there are still many students who do not understand the learning material delivered at school, so they must deepen the material outside of school learning. Especially since the COVID-19 pandemic hit, the effectiveness of learning activities has decreased because the learning process is carried out online which results in less interactive learning. Therefore, the EduAlecta application was created which is engaged in digital-based education. The EduAlecta app can help teachers increase their income and connect with students who need tutoring outside of school hours. The EduAlecta application system has the advantage of applying GPS so that students can determine the study location they want and students can arrange the tutoring they ordered. The method used in the front-end design is user centered design and the back-end design method uses waterfall.

Anxiety, depression, and suicidal ideation in patients with chronic dermatoses
Authors: Srivastava Gautam , Srivastava Govind
Published: August 2022

Skin is a source of great confidence and pride for an individual; a chronic disease affecting the skin can become a cause of constant stress and lack of self-esteem. Since the natural history of such diseases is very prolonged with periods of exacerbations and remissions, the psychological symptoms tend to increase in severity leading to anxiety, depression, and even suicidal ideations. Disorders such as acne, psoriasis, eczema, and alopecia are often associated with psychiatric comorbidities – psoriasis being the one with the most psychiatric aberrations. In general, the younger patients show more pronounced features of suicidal ideations when compared to other age groups. This parallel psychiatric aspect of skin diseases needs to be simultaneously addressed for the optimal treatment of both the physical and mental health of such patients.

Published: August 2022

This study is a review and a cumulative piece of work on Pt- and Au-based nanoparticles and H2 blockers drugs. It has been studied that Pt- and Au-based nanoparticles are used more often in different biomedical applications. Nanoparticles based on these two metals are highly biocompatible and can be used for the diagnosis of various diseases through in vitro imaging, tissue engineering, and drug delivery. The compatibility of Pt- and Au-based nanoparticles is increased using polymer-nanocomposite hybrids, which can participate in delivering a large number of drugs to modulate and improve the biodistribution and uptake of drugs on the cellular level. Another part of this review focuses on H2 blocker drugs. These drugs are specific classes for the suppression of gastric juice or acids under different gastrointestinal conditions. Famotidine has also been reported as a marker drug for COVID-19 patients. This review provides cumulative information on H2 blocker drugs and nanoparticles in single articles and specifies their role in different treatments associated with different types of cancers, gastrointestinal disorders, and COVID-19.
Surgical management of post-COVID invasive rhino-orbito-cerebral mucormycosis and its outcomes: Role of neurosurgeons in a tertiary care center
Authors: Das Anand Kumar , Mani Suraj Kant , Singh Saraj Kumar
Published: August 2022

Background:

Mucormycosis, which was previously considered to be rare, has emerged with a new challenge in patients infected with or recovering from COVID-19. Immunocompromised patients are particularly prone to developing this disease. The most common form of presentation is rhino-orbito-cerebral mucormycosis (ROCM). We present various neurosurgical approaches to an entire spectrum of its clinical manifestations.

Methods:

This is a retrospective study of patients who were admitted to the neurosurgery department with ROCM and a history of COVID-19 infection between November 1, 2020, and September 1, 2021. All cases of ROCM underwent contrast-enhanced computed tomography/magnetic resonance imaging of the brain, paranasal sinuses, and orbit. A tissue biopsy was sent for histopathological analysis. All confirmed cases received liposomal amphotericin B and surgical treatment was immediately undertaken.

Results:

Out of 200 patients with ROCM, 40 patients presented with neurological manifestations. Seven out of 40 patients had focal lesions in the brain and skull bone that needed neurosurgical intervention along with sinus debridement and antifungal treatment. These seven patients presented with different clinical manifestations: large-vessel stroke (one), medium-vessel stroke (one), frontal lobe abscess (one), frontal bone osteomyelitis (two), isolated central nervous system involvement (one), and mucor mimicking trigeminal schwannoma (one). The surgical intervention included decompressive craniectomy, frontal craniotomy, subtemporal craniotomy, and a minimally invasive supraorbital keyhole approach.

Conclusion:

In high-risk patients, a high level of clinical suspicion combined with appropriate investigations should be performed as soon as possible. Symptoms and early warning signs should not be overlooked, as treatment delays can be fatal. A minimally invasive surgical approach is possible in view of decreasing the morbidity of large craniotomy.
Intraosseous schwannoma in the clivus mimicking chordoma treated with endoscopic endonasal surgery: A case report
Authors: Ishikawa Takaaki , Akutsu Hiroyoshi , Hara Takuma , Tanaka Shuho , Masumoto Tomohiko , Ishikawa Eiichi
Published: August 2022

Background:

Intraosseous schwannomas are extremely rare and they have not yet been reported to occur in the clivus. We report a schwannoma in the clivus mimicking chordoma and review intraosseous schwannomas of the skull.

Case Description:

A 62-year-old man presented with gradually worsening hoarseness with dysphagia and atrophy of the left tongue, trapezius muscle, and sternocleidomastoid muscle. Magnetic resonance imaging showed that the tumor was mainly located in the clivus, and a computed tomography (CT) scan revealed an osteolytic lesion with expansion of the clivus and preservation of the bony cortex. Endoscopic endonasal surgery was performed to diagnose and treat symptoms. The tumor was subtotally removed without any complications. The histopathological findings revealed typical schwannoma, which showed Antoni A and Antoni B patterns positive for S100 protein. Based on the preoperative imaging, intraoperative and histopathological findings, the tumor was considered to be an intraosseous schwannoma in the clivus, and no recurrence was observed after 1 year of postoperative follow-up.

Conclusion:

Even though the intraosseous schwannoma in the clivus is uncommon, it should be considered as a differential diagnosis if an expansive lesion without destruction of the cortical bone is shown on CT as well as iso-hyperintensity on T2-weighted magnetic resonance imaging.
Double bypass for mycotic middle cerebral artery aneurysm
Authors: Rennert Robert C. , Budohoski Karol P. , Mortimer Vance R. , Couldwell William T.
Published: August 2022

Background:

Ruptured intracranial mycotic aneurysms have high morbidity and mortality and present unique surgical challenges because of vessel friability.[1] Flow-preserving strategies are needed for more proximal lesions that cannot be treated with vessel sacrifice.

Case Description:

A 33-year-old man with no medical history who presented with fevers and peripheral septic emboli was found to have infective cardiac valve vegetations. He reported headaches and left arm weakness; an irregular 7 × 8 × 9 mm bilobed middle cerebral artery mycotic aneurysm involving multiple M3 branches with subarachnoid hemorrhage was found on cranial imaging. Multifocal and small intraparenchymal hemorrhages from septic emboli were also seen. Clip trapping and revascularization were recommended. A right frontotemporal craniectomy was performed, preserving the superficial temporal artery. After extradural exposure, a hole was drilled in the middle fossa floor lateral to the foramen ovale. The Sylvian fissure was split and the larger M3 branch was isolated. An endoscopically harvested saphenous vein graft was anastomosed to the cervical external carotid artery, tunneled through the middle fossa floor, and anastomosed end-to-side to the larger M3. The aneurysm was clip trapped and the involved smaller M3 was transected and anastomosed end-toend to the superficial temporal artery. Indocyanine green videoangiography confirmed patency of both bypasses. Postoperatively, the patient received antibiotics and a mitral valve replacement. He was neurologically intact on 1-month and 2-year follow-up.

Conclusion:

Although technically demanding, tailored revascularization and clipping of ruptured mycotic cerebral aneurysms are a viable treatment option for these complex lesions.
BANK'S OPERATIONAL RISK MANAGEMENT MECHANISMS IMPROVEMENT
Authors: Mishchenko Volodymyr , Naumenkova Svitlana
Published: August 2022

The article examines the mechanisms and methods of operational risk management in Ukrainian banks. It is determined that operational risk is a complex type of banking risk, and the peculiarity of its implementation is that it is inherent in all banking processes, products, business lines and activities and has an unpredictable nature. It is proved that the improvement of operational risk management contributes to the sustainable functioning of banks and the stability of the entire banking system. The main principles of the bank's operational risk management system formation and functioning are determined, which include: objectivity and regularity of risk identification and assessment; timeliness of their detection and evaluation; complexity; structured management; proportionality; delimitation of control functions and operational activities; independence of individual governing bodies; confidentiality; transparency and efficiency. Given the complex and dynamic nature of operational risks, as well as the active digitalization of the banking business, it is recommended that operational risks include reputational risks, information risks and cyber risks. Based on the calculations, it is established that the impact of operational risks on the performance of domestic banks tends to increase, the leveling of which requires the development of new management mechanisms through the creation and effective operation of operational risk management. A system of measures to improve operational risk management based on the use of the «three lines of protection», which includes classification, identification, measurement, monitoring, control and reporting of operational risks, as well as assessment of economic and social consequences of risk events. The main methods of operational risk management are identified and it is proved that the key direction of their use should be preventive measures to avoid or minimize the economic consequences of risks, and coverage of losses arising from their implementation should be provided by specially formed reserves of internal capital. An indicative list of key indicators has been developed and approaches to characterizing operational risk events that can be used by domestic banks in practice to minimize the consequences of operational risks have been improved.

The importance of applying a scientific approach to the identification of classification features of the studied concept allows to increase the validity of the choice and ensure high efficiency of investment, which directly affects the development of not only the economy but also other spheres of life. In the article the author studies the views of leading economists and features of the legislative interpretation of the studied concept. Considering the main approaches to the definition of investment, we conclude that this concept is quite multifaceted, specific to different countries based on the level of development, socio-cultural characteristics and manifests itself as a financial and economic category. It was found that the contradictions are due to the interpretation of the concept of «investment» from different positions, according to each area of ​​their study. Therefore, it is proposed to consider this category in different aspects (financial, economic, macroeconomic, technical, industrial, etc.), which will emphasize the importance of certain aspects in certain areas in the formation of the concept of «investment», without narrowing its essence. Based on the considered definitions of the essential characteristics of investment, the author's vision of the interpretation of the «investment» concept is proposed. The multifaceted interpretation of the concept of "investment" gives rise to various approaches to the classification of of this financial and economic category types, which prompted the author to systematize scientific approaches and form a generalized classification of investment types by basic classification criteria. A new type of investment has been proposed – land leasing investments, which are relevant for strengthening the country's defense capabilities and restoring military strength, assistance and protection of the population, can be used as a result of force majeure, including war. The use of a systematic classification will allow a more detailed approach to the study of the nature of investment processes that occur at all levels of economic entities' economic activity. The practical aspect of the generalized and proposed classification of investment types can be further used in statistical research and analysis of the investment market.

The article is devoted to the study of the peculiarities of legal protection of corporate property rights of members of a limited liability company. It was established that the corporate property rights of the company members mediate the process of their property participation in the organization's activities. The publication focuses on the legal nature and peculiarities of the realization of property rights, which have been legally established at the legislative level, in particular: the right to payment of the value of the share in the event of leaving the company; the right to the payment of dividends, the preferential right to purchase a share of another member of the company, which is alienated to a third party; the right to receive part of the property remaining after settlements with creditors in case of liquidation of the company; the right to alienate a share (part thereof) to other participants or third parties on a paid or free basis. The specified rights are differentiated by the authors according to the criterion of the presence or absence of attachment to the size of the share of the authorized capital. Attention is focused on restrictions on the exercise of individual rights. It was established that in addition to property rights, which are regulated at the legislative level, members of a limited liability company can acquire corporate property rights, which are enshrined in the founding documents. On the basis of the conducted analysis, it was concluded that despite the attempt made to improve the regulation of relations related to the realization of corporate property rights, both at the doctrinal level and in practice, a number of unresolved problematic issues remain.

The article deals with the issue of factual grounds for conducting investigative (search) actions during a pretrial investigation in criminal proceedings. An analysis of national criminal procedural legislation, which regulates the procedure and grounds for conducting investigative (search) actions, is carried out. The author offers an opinion according to which the establishment of information that forms the basis of a decision to conduct an investigative (search) action, as well as the assessment of their sufficiency, depend on a number of components: the formulation of the basis of the investigative (search) action in the law, which may contain an indication of the need substantiation of the investigative (search) action with any data; from the degree of limitation of the rights and freedoms of the trial participants by the action of the investigator; from the procedural status of a participant in a pretrial investigation, in respect of which an investigative (search) action is being conducted; from the requirements of the law regarding the execution of a decision to conduct an investigative (search) action (the need to issue a motivated resolution, judge's decision). The diverse nature of the interpretation of the factual grounds for conducting investigative (search) actions is explained by the uncertainty of the position of the legislator himself. We believe that the category "ground" should have a fairly clear meaning; the basis cannot be determined by the purpose of the investigative (search) action, and therefore, it is necessary to formulate it in the law in an appropriate manner in relation to the conduct of all investigative (search) and other procedural actions. The author does not agree with the position according to which the actual grounds for conducting an investigative (search) action can be established exclusively by evidence obtained in the manner prescribed by the criminal procedural law. The author's definition of the factual grounds for conducting investigative (search) actions is proposed, which means the presence of sufficient factual data obtained as a result of procedural actions, during which a statement (notification) about a committed criminal offense was received, items and documents were seized (temporary access to things and documents, detention), received other evidence (investigative (search), secret investigative (search) actions) and make it possible to reasonably believe that during such an investigative (search) action, new or confirmed existing evidence will be obtained, which has significance for criminal proceedings.

Published: August 2022

Sustainable development of urban transport systems is an urgent task of the modern world. High population density and a significant number of industrial enterprises and enterprises in the service sector require not only ensuring the mobility of city residents and the economic activity of enterprises, but also the creation of comfortable living conditions with the preservation of ecology and natural parks in the urban landscape. Incorrect transport planning of the late 20th and early 21st centuries led to rapidly growing motorization and long traffic delays. The created concepts of the development of the transport infrastructure of large cities require constant measurement of the results of changes and correction if necessary. First of all, the work defines the concept of "city transport systems" and their classification. Social and non-social (quantitative, qualitative) indicators used to characterize urban transport systems are described. The main requirements for the urban monitoring system and its key structural elements are given. A monitoring system is proposed, in which the basic management goals related to infrastructural changes (Task 1), the attitudes of users of transport services (Task 2), as well as the impact on the economy (Task 3) and development costs (Task 4) are highlighted. 5 groups of indicators have been formed, which can be used to monitor the development of the city's transport systems: intensity, safety, accessibility, convenience and connectivity. Among the indicators, there are both indicators of objective assessment ("hard" indicators) and indicators of subjective assessment ("soft" indicators). The information base of the article consists of publications by prominent Ukrainian and foreign scientists, data from the Tom Tom transport analytics service, and the current legal framework of Ukraine, which regulates urban transport systems, and urban development strategies. The following methods of scientific research were used for the research: dialectical method, method of scientific abstraction, method of content analysis, method of analysis and synthesis, comparative method, method of generalization and graphic method.
