La producción de varios prototipos se traduce en mayores costos en la etapa de diseño y optimización de un múltiple de admisión. El objetivo de esta investigación radica en el análisis de datos de velocidad de fluido arrojados por la simulación fluido dinámica de distintas geometrías de unas toberas de admisión de alto rendimiento. En fase inicial se usó la modelación teórica, la representación de un objeto en el plano abstracto para caracterizarlo, en la fase de análisis de resultados, fue el método comparativo, donde se observó los datos obtenidos mediante un estudio paralelo. La relevancia de la investigación radica en la obtención de ganancias porcentuales en velocidades mínimas hasta del 271% mientras en velocidades máximas hasta del 52%. Se concluye que la razón de los resultados se da al modificar el diámetro de las toberas versus su longitud. Se demostró la efectividad de este tipo de simulaciones, con el fin de impulsar estudios posteriores en el área de diseño para elementos mecánicos.

Fraud Hexagon: Detection of Fraud of Financial Report in State-owned Enterprises in Indonesia
Authors: Sudrajat Sudrajat , Suryadnyana Nyoman Adhi , Supriadi Taufiq 
Published: June 2023

This study aims to identify the potential for fraudulent financial reporting using the Fraud Hexagon approach with pressure, capability, collusion, opportunity, rationalization, and ego indicators. The population in this study is state-owned companies with observations for 12 years, from 2010 to 2021, and uses regression analysis with SPSS tools to test the Hypothesis. The results showed that pressure and ego could detect the potential for fraudulent financial reporting. There is a tendency for management to report conditions that are different from the actual conditions when under pressure in the form of performance targets that are not supported by the resources they have. CEO duality also provides an excellent opportunity for fraudulent financial reporting practices because when there is a position war, there is no cross-check between departments, so other parts cannot detect the potential fraud committed by the CEO. This condition also indicates weak control processes that provide wider opportunities for fraudulent financial reporting. At the same time, variables of ability, collusion, opportunity, and rationalization cannot detect financial statement fraud. This condition is because state-owned companies are required to implement the Minister of Finance Regulation number PER-11/MBU/07/2021 and the Financial Services Authority number 13/POJK.03/2017 as the basis for the implementation of Good Corporate Governance so that it is possible to commit financial reporting fraud very small.

Published: June 2023

Peptide mapping is a key method for studying the primary structure of proteins. With its sensitivity to the slightest changes in the covalent structure of a protein, this method is applicable both to medicinal product identification at the control stage and to production process stability monitoring.The aim of the study was to develop and validate a peptide-mapping procedure for the identification of a novel highly glycosylated recombinant C1 esterase inhibitor.Materials and methods. The authors studied recombinant human C1 esterase inhibitor products and trypsin. The study involved peptide mapping using reverse-phase high-performance liquid chromatography and high-resolution mass spectrometry. The following statistics were calculated to evaluate the results: mean, standard deviation, and coefficient of variation. The validation parameters included specificity, precision, and robustness.Results. The authors tested several variants of sample preparation for tryptic digests, including additional N-glycanase treatment and complete deglycosylation, and established the optimal conditions for sample preparation and chromatographic separation of C1 esterase inhibitor peptides to obtain consistent chromatographic profiles (peptide maps). The authors identified characteristic peaks and the corresponding relative retention time and area ranges. The absolute retention time of the second (characteristic) peak was approximately 16.5–16.9 minutes. The relative retention times were 2.14–2.21 for peak 9, 2.55–2.64 for peak 12, 2.97–3.14 for peak 14, 3.11–3.29 for peak 15, and 6.20–6.63 for peak 28.Conclusions. The authors developed a peptide-mapping procedure for C1 esterase inhibitors and optimised the conditions to achieve an over 18-hour reduction in sample preparation time. This procedure met the established acceptance criteria for specificity, precision, and robustness.

Published: June 2023

Objective — to evaluate the dynamics of sleep quality and duration, as well as quality of life after 12 months of follow‑up in patients with moderate to high cardiovascular risk against the background of stress caused by military actions.
Materials and methods. The prospective, open, non‑placebo controlled investigation has been conducted over 12 months with participation of 87 patients with moderate to high cardiovascular risk. Women prevailed among patients (50 (57.5%)), the mean age was (59.39±12.09) years. Obesity of I degree was established in 47.1%, II degree obesity in 32.3%, III degree obesity in 11.8% of patients, and excessive body mass was registered in 8.8% of the examined subjects. There were no subjects with normal body mass. At baseline, essential hypertension of various stages was established in 58.9% of patients. All patients underwent assessment of cardiovascular risk based on Framingham scale, index of quality of life with SF‑36 «Health Status Survey» questionnaire, stress level with Perceived Stress Scale, presence of sleep disorders with the use of criteria of the International Classification of Sleep Disorders (2014), as well as measurement of anthropometric parameters.
Results. The prevalence of stress was 100.0% with no significant difference between women (99.8%) and men (100.0%), (OR=0.96 with 95% CI 0.72—1.28). At baseline, circadian disturbances of sleep and alertness prevailed in patients (41%), while after 12 months of observation, insomnia was more common in the entire observation group (55.8%). At the end of the study, the number of patients who had difficulty falling asleep increased (from 35.3% to 81.2%, р <0.05), who had difficulty maintaining uninterrupted sleep (from 38.2% to 66.6%, р <0.05), who had awakening before the planned time (from 58.8% to 75.0%, р <0.05), who had nausea/vomiting as a manifestation of sleep disturbance (from 17.6% to 37.5%, р <0.05), who had deterioration of attention/concentration/memory (from 58.8% to 77.1%, р <0.05).
Conclusions. Against the background of chronic stress, insomnia prevailed among all sleep disorders in patients with moderate to high cardiovascular risk. As a result of the study, the significant decrease in the quality of life index from 69.7% to 43.2% has been established in this category of patients against the background of chronic stress.

Authors: Chernyavs'ka Iryna , Klemiatin Akim 
Published: June 2023

In current conditions, the issue of reducing the potential negative impacts on project stakeholders, improving efficiency, and increasing satisfaction from participating in project work remains relevant in project communications management.
The article aims to study the problems of defining and using the most effective communication channels in project stakeholder management. The theoretical and methodological basis of the work is a set of principles and methods of scientific research: the principle of systematization and theoretical generalization, methods of grouping and ranking.
According to the goal, the task was set to substantiate the effectiveness of communication channels depending on the degree of remoteness of the project stakeholders. Based on the study, the concept of a project was clarified, which, according to the PMBOK Project Management Standard, is understood as a temporary activity aimed at creating a unique product, service, or result and is part of the value delivery system. The contextual factors of the internal and external environment of the organization, which influence the project's results, were studied. The basis for the analysis was the scientific works of domestic and foreign scientists on the mentioned issues, materials, and data from the official website of the Ukrainian Project Management Association.
The theoretical and methodological basis of the work is a set of principles and methods of scientific research: the principle of systematization and theoretical generalization, methods of grouping and ranking. As a result of the study, the sphere of execution, "Stakeholders," which is one of the eight spheres of project implementation, was considered. The definition of communication as a vital part of the value supply system by the sphere of execution of the "Stakeholders" project was recorded, and the dependence of the effectiveness of communication methods on the used communication channels was determined according to the model of the effectiveness of communication channels by Alistair Cockburn. It has been proven that applying this model can have a beneficial effect on increasing communication effectiveness during project implementation. A matrix of the effectiveness of communication channels was built, which details the consequences of stakeholder communication methods depending on their remoteness.
ORGANISATION OF ACCOUNTING AND ANALYSIS OF THE USE OF BUDGETARY FUNDS BY THE UKRAINIAN SSNS
Authors: Khmelyuk Alona , Hudz Alina 
Published: June 2023

The article summarises and substantiates methodological issues related to improvement of the organisation of the accounting process of budgetary institutions and analyses the use of budgetary funds under conditions of uncertainty (martial law). Based on the materials of reliable accounting and financial statements of the 1st State Fire and Rescue Unit of the Main Directorate of the State Emergency Service of Ukraine in the Dnipro region, methodological approaches to accounting for exchange and non-exchange transactions are determined. The basic principles of accounting organisation and elements of formation of the accounting policy of a strategic budgetary institution are analysed. The form of accounting as locally unified (automated) is evaluated and the accounting registers and their method of formation are presented. The study of the regulation of accounting records has made it possible to identify certain features in terms of regulatory and legislative subordination. In particular, it is emphasised that the Methodological Council on Accounting in the Ministry of Internal Affairs of Ukraine contributes to ensuring uniform methodological approaches to the organisation of the accounting process. It is established that the formation of accounting records in the institution is carried out on the basis of the Working Chart of Accounts, which is formed with the preservation of the account classes of the Chart of Accounts in the public sector. It has been proved that local automation of accounting for all business transactions facilitates control over the use of budgetary funds and promotes the introduction of uniform methodological accounting principles. Based on the reliable financial statements of a budgetary institution, an analysis of dynamic changes in the structure of expenditures by elements of expenditures on exchange operations is carried out. The results of the analysis led to forecasts of expenditures for a short-term period of one year.
The paper develops methodological approaches to forecasting calculations. It proves the impossibility of using trend equations as the main method of forecasting economic phenomena under conditions of uncertainty (martial law). An algorithm for forecasting the volume of expenditures based on the use of the rate of acceleration of dynamics as a multiplier is presented. The methodology of calculation was used in the course of the study and the forecasting of expenditures for the next reporting period was carried out. It is proposed to apply the obtained results as a calculation of the institution's allocation plan for the next reporting period under conditions of uncertainty (martial law).

Published: June 2023

The article provides a theoretical substantiation of methodological approaches to organisation of accounting, control and analysis of production stocks. The regulatory framework is evaluated and the main stages of its functioning are outlined. The main components of the accounting policy elements of production inventories have been identified. The algorithm for forming an effective organisation of production inventory accounting is outlined and tested. Based on the reliable financial statements of PJSC "Dnipro Mineral Fertilizer Plant", the presented methodology for organising accounting, control and analysis of production inventories has been tested. The basic principles of documenting operations of production stocks are studied and peculiarities in terms of inventory recording at a chemical enterprise are identified. A scheme of document flow of inventory movement has been developed. In the course of the study, a comparative analysis of judgements on determining the value of production stocks according to the national and international methods of their reflection was carried out. The main differences in the methods of valuation of inventories for their disposal are identified and characterised. It has been concluded that the valuation of inventories by the FIFO method in martial law is inappropriate. The paper assesses the accounting treatment of production inventories. The organisation of synthetic inventory accounting is described and a journal of business transactions on inventory movements for the month of the current year is formed. It has been established that the organisation of inventory accounting is carried out in accordance with the current regulatory framework and the Order "On Accounting Policy at an Enterprise". In the course of the study, certain conditions for the occurrence of irrelevant production inventories were accepted. The basis for these judgements is the analysis of accounting records on inventory movements. The mechanism for applying decision-making models under conditions of uncertainty is implemented. The analytical table was used to calculate the loss in a discrete situation. On the basis of the calculations, analytical conclusions are formulated. The effectiveness of applying the decision-making model "Minimisation of maximum regret" has been proved. The resulting model allowed to complete analytical conclusions and prove the effectiveness of the use of accounting and analytical reflection of production stocks in order to make effective management decisions.

Girlhood as Storytelling and (Anti-)creation in Dodie Smith's I Capture the Castle
Authors: Szirák Anna 
Published: June 2023

Abstract
The power of imagination and the capacity for storytelling can mirror creation and God-like capabilities: anything can occur if one can imagine it. Observing this connection between narrator and God, in this article I analyze the representation of girlhood in British author Dodie Smith's I Capture the Castle (1948). I show how protagonist and narrator Cassandra uses the framework of her girlhood to narrate and create the lives of those around her and examine the ways in which her power alters as she begins to enter the stage of grown womanhood. With a close reading that understands Cassandra's storytelling powers as Biblically structured, I consider the narratorial possibilities of girlish fantasy and father-daughter dynamics.
