Abstract
This research presents a machine learning-based approach aimed at optimizing the rate of penetration (ROP) in S-shaped wells. The method uses historical drilling data from wells in Southern Iraq to find out the best drilling operating variables. Dynamic Time Warping (DTW) is applied to prioritize data from wells with similar characteristics to enhance relevance. The framework is adaptable, incorporating new field data and expert insights as necessary. The performance of the method was evaluated by comparing the results to existing well data, with clear improvements identified.
Initially, two machine learning models—Extra Trees Regressor and XGBoost—were utilized to predict ROP using 17 different input factors, such as torque and SPP. The accuracy of these models was assessed using correlation coefficients, and Extra Trees Regressor, the more accurate model, was selected to proceed into the second phase.
Next, Particle Swarm Optimization (PSO), Genetic Algorithm (GA), and Firework Algorithm (FWA) were used to fine-tune key parameters like WOB, RPM, surface pump pressure (SPP), and flow rate to further improve ROP. The dataset comprised data from 6 wells, the data was partitioned to 75% to train the ML models and 25% to test them. In the prediction phase, the correlation coefficients for the models were: Extra Trees Regressor (0.99) and XGBoost (0.97) for the training set, and Extra Trees Regressor (0.96) and XGBoost (0.94) for the testing set. The average optimization improvements were 30.66% for GA, 22.33% for PSO, and 14.5% for FWA.

Introduction. Tourist-recreational sector is one of actively developing sector of economy. Development of tourist-recreational sector is of multiplicative nature, which means the joint development of catering, hotel services and hospitality industry, advertisement, agriculture, insurance, etc. The goal of the study is to analyze the local systems of tourist-recreational sector based on the example of Volga Federal District and reveal their major perspectives for development. The following indicators were chosen for the analysis 1) number of foreign citizens, housed in the territory of Volga Federal District in the collective and individual accommodation facilities; 2) number of Russian citizens, housed in the territory of Volga Federal District; 3) number of tourists, housed in sanatorium-and-spa institutions of Volga Federal District; 4) number of tourist organizations, performing activities with service consumers; 5) number of Russian tourists, sent to tours. Results. According to the analysis, Republic of Tatarstan takes the first place among the regions of Volga Federal District by number of foreign citizens housed in the hotels, Nizhny Novgorod oblast takes the second place, and Samara oblast - the third one. Republic of Tatarstan also takes the first place by number of Russian tourists sent to tours, Perm Territory takes the second place. Conclusion. The group of leading regions by tourist-recreational indicators (Republic of Tatarstan, Nizhny Novgorod oblast, Republic of Bashkortostan, Perm Territory) was revealed. Mari El Republic and Republic of Mordovia show low results in the tourist-recreational sector development. Thus, it is important to pay a particular attention to the tourist sector development in these regions.
МЕСТНЫЕ БЮДЖЕТЫ: ДОХОДЫ, МЕЖБЮДЖЕТНЫЕ ТРАНСФЕРТЫ, ДОЛГОВЫЕ ОБЯЗАТЕЛЬСТВА
Authors: Зотиков Н.З. , Урусова И.Н. 
Published: February 2025

Местные бюджеты являются главным звеном всей бюджетной системы России. Основными источниками доходов бюджетов различных уровней являются закреплённые за ними налоговые доходы, неналоговые доходы, а также межбюджетные трансферты. В статье анализируются роль и значение доходов местных бюджетов. Авторский подход заключается в том, что в статье рассматриваются доходы не отдельных видов местных бюджетов, а всех местных бюджетов в целом. Цель статьи – исследование проблемных вопросов формирования доходов местных бюджетов на основании официальных данных Минфина России. Исследованием установлено, что финансовые проблемы местных бюджетов, особенно муниципальных районов и поселений, заложены в самом налогово-бюджетном механизме, без внесения в него существенных изменений благополучие местных бюджетов недостижимо.
Introduction. The existing fiscal mechanism, in which certain tax revenues are assigned to each level of the budget system, has led to deficits of regional and local budgets, their subsidization; they need constant gratuitous injections from the federal center. Regional and local budgets were practically without funds for successful economic development. The aim and objectives of the study are to use the official data provided by the Ministry of Finance of the Russian Federation for a period of several years in order to analyze financial problems and their causes not only in relation to local budgets in general, but also to the budgets of municipal districts, municipal areas, rural and urban settlements. Methods. The study is based on such research methods as analysis and synthesis, grouping, generalization, table method, etc. The results obtained indicate an unsatisfactory financial condition of the budgets of municipal districts, urban and rural settlements that prevail in the structure of local budgets. Tax revenues assigned to local budgets (personal property tax, land tax) make up no more than 20-25 per cent of the local budget tax revenues; over two thirds of the local budget tax revenues accounts for the federal tax - personal income tax. A significant share of the total revenue of local budgets comes from gratuitous revenues, grants and subsidies which do not foster interest in the development of local territories, but only cover local budget deficits. Conclusion. The study confirmed that effective taxes should be assigned to local budgets, which would encourage interest of the local budgets in the development of their territories. This relates to the taxes received by local budgets before the introduction of the Tax Code of the Russian Federation: VAT, income tax. The practical relevance of the study is that its findings and suggestions can be used in the activities of the relevant branches of government in the development and enhancement of the fiscal policy.

Social Media Food Influencers and Follower’s Local Food Purchase Intention: A Parasocial Relationship Perspective
Authors: Syarif Rahmat , Sucipto Kiki Reski Ramdhani , Rimakka Al Isra Denk , Pratama Andi Ahmad Dzaki Maheza 
Published: February 2025

Background: The presence of Social Media Food Influencers (SMFIs) has created a new landscape in local food tourism. Despite extensive studies focusing on the crucial role of influencer marketing through the lens of parasocial relationships, how SMFIs can foster these relationships and consequently influence their followers' intentions to purchase local food remains underexplored.
Purpose: This research examines how the parasocial relationship between SMFIs and their followers influences the latter's intention to purchase local food.
Method: This research employed the quantitative approach. It involved 439 active Instagram users who follow SMFIs as research respondents. They were recruited using the purposive sampling technique. Additionally, using Smart-PLS software, the Partial Least Squares Structural Equation Modeling (SEM-PLS) was applied to statistically test the data and the research hypotheses.
Findings: This research reveals that influencers' content value (informative value), interaction strategy (interactivity), and credibility (expertise and attractiveness) positively and significantly influence the parasocial relationship between followers and social media food influencers (SMFIs). The results also indicate that this parasocial relationship influences followers' intention to purchase local food.
Conclusion: This study highlights the critical role that food influencers play in fostering parasocial relationships, which significantly influence followers’ intentions to purchase local food. The findings reveal that the effectiveness of food influencers is largely contingent upon their ability to engage followers through informative content, interactive communication, and the establishment of perceived expertise.
Research implication: The research findings offer significant implications for tourism marketers and local food business managers. Social media food influencers can be regarded as influential promoters of local food, enhancing tourists’ interest and purchase intentions through the parasocial relationships facilitated by social media.

Published: February 2025

Penelitian ini bertujuan untuk menganalisis prediksi kebangkrutan pada perusahaan makanan cepat saji yang terdaftar di Indeks Saham Syariah Indonesia (ISSI) dan terkena dampak aksi boikot dengan menggunakan Model Springate sebagai metode evaluasi. Fokus penelitian adalah untuk menentukan tingkat risiko kebangkrutan dan mengidentifikasi perusahaan dengan potensi kebangkrutan tertinggi selama periode 2021-2023. Data yang digunakan adalah data sekunder yang diambil dari laporan keuangan triwulanan perusahaan. Metode analisis menggunakan pendekatan kuantitatif dengan Model Springate yang mencakup empat rasio utama: modal kerja terhadap total aset, laba sebelum bunga terhadap total aset, laba sebelum pajak terhadap liabilitas lancar, dan penjualan terhadap total aset. Hasil penelitian menunjukkan bahwa sebagian besar perusahaan dalam sampel berada dalam zona risiko kebangkrutan, terutama perusahaan dengan rasio likuiditas dan profitabilitas yang menurun secara signifikan. Secara khusus, perusahaan dengan skor Springate di bawah ambang batas 0,862 dianggap berpotensi bangkrut. Temuan ini memberikan wawasan bagi manajemen perusahaan untuk mengantisipasi risiko finansial dan dapat dimanfaatkan oleh para pemangku kepentingan untuk mendukung keputusan investasi serta pengembangan strategi keuangan di masa depan.

Abstract
This study aims to analyze the prediction of bankruptcy in fast food companies listed on the Indonesian Sharia Stock Index (ISSI) and affected by boycotts using the Springate Model as an evaluation method. The focus of the research is to determine the level of bankruptcy risk and identify the companies with the highest potential for bankruptcy during the 2021-2023 period. The data used is secondary data taken from the company's quarterly financial statements. The analysis method uses a quantitative approach with the Springate Model which includes four main ratios: working capital to total assets, profit before interest to total assets, profit before tax to current liabilities, and sales to total assets. The results show that most of the companies in the sample are in the bankruptcy risk zone, especially companies with significantly decreased liquidity and profitability ratios. Specifically, companies with a Springate score below the threshold of 0.862 are considered potentially bankrupt. These findings provide insights for company management to anticipate financial risks and can be leveraged by stakeholders to support investment decisions and the development of future financial strategies.

Authors: Kato Takenori , Hasegawa Toshinori , Kuwabara Kyoko , Ohno Masasuke , Kuramitsu Shunichiro , Naito Takehiro , Mizuno Akihiro , Sakai Yosuke , Oishi Hiroyuki 
Published: February 2025

BACKGROUND
The management of recurrent brain metastases after initial stereotactic radiosurgery (SRS) remains challenging, with high local recurrence rates following salvage surgery. While preoperative SRS has shown promise for newly diagnosed metastases, its application in post-SRS recurrences is largely unexplored.

OBSERVATIONS
The authors treated three patients with recurrent brain metastases using preoperative re-irradiation followed by resection. Gamma Knife SRS was performed at marginal doses of 16–18 Gy, followed by resection within 24–48 hours. Local control was achieved in all patients without radiation-related complications. Histopathological examination confirmed the presence of viable tumor cells and radiation-induced changes. Follow-up magnetic resonance imaging revealed no evidence of tumor recurrence or adverse effects. Two patients remained alive at 35 and 19 months, whereas one died of primary cancer progression at 20 months.

LESSONS
Preoperative re-irradiation followed by resection for recurrent brain metastases after initial SRS is feasible and offers promise for short-term safety, local control, and rapid symptom improvement. The ability to promptly implement SRS enables its application in oncological emergencies. These findings suggest that preoperative re-irradiation can be a valuable strategy for managing symptomatic post-SRS recurrent brain metastases that require prompt surgical intervention.

THE PRINCIPLE OF "FUNCTIONAL DIVERSITY" IN THE ORGANIZATION OF OPEN PUBLIC SPACES IN CITIES
Authors: Husiev Mykyta 
Published: February 2025

A study of the experience of developing open public spaces in cities has made it possible to identify common features of their functional and spatial organization. The organization of any open public space in cities is based on specific principles by which it is formed: general principles, as well as special principles. The theoretical and practical experience of organizing open public spaces in cities is analyzed, on the basis of which the common features of their functional and spatial organization are derived. The importance of forming an open public space of cities is shown by deriving specific principles of its organization. The principle of "functional diversity" is to fill open public urban space with functions that can interest and satisfy the social needs of as many different groups of people as possible, regardless of their status, condition, or age. The principle of "functional diversity" is considered in detail, and the techniques that reveal it are identified. The author lists which of the general and special principles of organization of open public spaces in cities can be identified using the techniques discussed in the article. On the example of the project implemented by the author, recommendations are given for the organization of open public spaces in cities based on techniques that reveal the principle of "functional diversity". The relevance of the issue of deriving specific principles for the organization of open public spaces in cities (in particular, the principle of "functional diversity" and the techniques that reveal it) is due to the need for methodological and practical recommendations on the physical and functional content of various types of open public spaces in cities for their activation, attraction of people and comfortable stay in them, taking into account the world experience of their functional and spatial organization.
