Magnetohydrodynamics analysis of magnetorheological fluid damper
Authors: Tharehalli Mata Gurubasavaraju , M. Muralidhar Singh
Published: July 2023

A key feature of magnetorheological fluid is its variability of rheological properties in which upon exposing this fluid, the viscosity of the fluid changes accordingly. Hence this nature can be implemented in various engineering applications. To understand its influence in a magnetorheological (MR) damper, it is essential to study the flow behaviour using computational and numerical methods. The main objective of this work is to estimate the influence of the external magnetic field on the fluid flow velocity inside the damper using magnetohydrodynamic analysis. Finite element analysis, magnetostatic analysis, and magnetohydrodynamic (MHD) analysis have been carried out to investigate the change in the shape of the velocity profile across the flow gap of the monotube MR damper under the various magnitude of magnetic force using the MHD module of ANSYS fluent software. The simulation is conducted by considering laminar, steady-state, and incompressible fluid flow. In finite element analysis, the magnitude of magnetic flux density (MFD) ‘B’ was evaluated at various direct currents. Later, obtained MFD has been applied perpendicular direction to the flow of MR fluid. The effective length of the fluid exposed to the MFD is taken as 2 mm to 28 mm in an overall flow length of 30 mm. The extracted results have shown that the fluid flow velocity reduces with an increase in the magnetic flux density. It has been observed that 10.42 % reduction in velocity upon increasing the magnetic flux density from 0.25 T to 1 T at 75 kPa pressure. The reason for a reduction in velocity is because of variation in the rheological properties of the fluid under the magnetic field, which is very much essential to produce a good damping effect in the MR damper.

Published: July 2023

This study explored the employment of advertising texts as tools for teaching grammar to for-eign learners of English, as their constituent organisation is assumed to enhance the understanding of some grammatical details. Ten advertisements of beverages, banks, telecommunications, condiments, cream, and soap served as the research material. After the application of the grammar of interaction to the communicative components, the tables and graphs functioned to calibrate the grammatical mnemonics and semantic resources of the clauses. This study analysed the use of orthographic clauses, Six Countries, Six Voices, and One Song;alphanumeric clauses, Dial *966*911# to stop debit transactions on your account; and compounding, DataPlus, Smartphone as qualities of advertising. One also observed novel constructions such asEazyBanking and Souper; acronyms, as in UBA United Bank for Africa; and hash-tag as in #EachForE-qual, as well as the deployment of interspersed and splintered grammatical entities such as Starting from 17:59, Olympic Gold Medalist, Cheers to those who came before us and Pledge to drink right. The authors suggest that applications of the textual devices characteristic of advertising in the university classroom might encourage learners to practise the grammar of English.

Published: July 2023

Currently, in the education system of our country, interest in the diagnosis and assessment of the personal development of the child is again increasing. Moreover, the approach that the modern education system offers is characterized by scale and structure. Educational institutions have been offered new federal state educational standards. The standard indicates that the assessment of the personal results of students should be carried out in the aspect of the readiness and ability of students to self-development, the formation of motivation for learning and cognition, the development of value and semantic attitudes of students, reflecting their individual and personal positions, the development of social competencies and personal qualities, as well as the foundations of civic identity. Requirements for achieving personal results in regulatory documents are not supported by diagnostic tools – diagnostics. Educational results are proposed to be developed by educational organizations independently, which cannot but cause them difficulties. The indicated problem can be solved by creating a diagnostic apparatus for assessing the pedagogical conditions of personality-oriented education in a particular educational organization, taking into account the age characteristics of children. The article reveals the methods of assessing personal results and pays special attention to the method of mapping.

Published: July 2023

Introduction. Design education in Russia has been going through a complex, more than a century-long path of reforming and reorganizing educational institutions and the pedagogical process. The rethinking and processing of pedagogical concepts in the fields of education focused on training in-demand specialists takes place in parallel with external global processes on the basis of existing and new scientific knowledge, technology development, as well as ideas about the creative potential of the individual as a whole, and the tasks of the designer as a specialist, in particular, which is acutely relevant in modern realities. The purpose of the article is to study the semantic content of such key terms for pedagogy as the educational field and the education system, as well as the derivation of design education into a separate educational system. Methodology and methods of research. The methodological basis of the research was the following scientific methods: the phenomenological method, through which we identified the main features of the use of certain terms in contradictory meanings, in particular such terms as “educational environment”, “educational field”, “educational industry”, “subject area”; structural and functional method analyzing stable relationships and the relationship between the elements of the concepts considered in the article; the method of comparative analysis, which allowed us to identify common and different in the concepts under study and offer our own vision of the design education system at the present stage. The result of our research is the conclusion that design education, having a special subject area (area of professional activity), can be defined into a separate educational system, meeting the needs of the modern design industry. As a conclusion, we propose to consider design education from the point of view of an independent educational system, which will enable educational institutions to revise the structure and content of design education to increase efficiency in training highly qualified specialists and, as a consequence, to increase the level of economic achievements of the country.

The history of the development of the regular straight stem in hip arthroplasty
Authors: Wellauer Hanna , Heuberger Roman , Gautier Emanuel , Tannast Moritz , Steinke Hubert , Wahl Peter
Published: July 2023

Since the middle of the 20th century, total hip arthroplasty has become a very successful treatment for all end-stage diseases of the hip joint. Charnley solved with his low frictional torque arthroplasty the problem of wear and friction with the introduction of a new bearing couple and the reduction of the head size, which set the prerequisite for the further development of stem design.

This narrative review presents the major developments of regular straight stems in hip arthroplasty. It does not only provide an overview of the history but also assembles the generally scarce documentation available regarding the rationale of developments and illustrates often-unsuspected links.

Charnley's success is based on successfully solving the issue of fixation of the prosthetic components to the bone, using bone cement made of polymethyl-methacrylate. In the field of cemented anchorage of the stem, two principles showing good long-term revision rates emerged over the years: the force-closed and the shape-closed principles.

The non-cemented anchorage bases on prosthesis models ensure enough primary stability for osteointegration of the implant to occur. For bone to grow onto the surface, not only sufficient primary stability is required but also a suitable surface structure together with a biocompatible prosthetic material is also necessary.

Published: July 2023

In this paper, a new accelerated extrapolation Krasnoselski-Mann type algorithm for finding common element in the solution set of the hierarchical fixed point and split monotone variational inclusion problems are introduced in the setting of a real Hilbert space. We then prove that a sequence generated by the algorithm converges strongly to such common element which also approximates solution of some fixed point problem of demimetric mapping in the space. Finally, some applications and numerical experiment are given to show effectiveness of the proposed algorithm over the recently known related results in the literature. The established results extend and generalize many recent ones announced in the literature.

Published: July 2023

The Bromo Tengger Semeru National Park (or Taman Nasional Bromo Tengger Semeru/TNBTS) is a popular tourist destination in Indonesia, and the local authorities encourage the development of new local specialty products. One locally available commodity is coffee. This study investigated the best formula for Tengger herbal coffee. The randomized block design (RBD) consisted of two factors, including the coffee types (i.e., Arabica, Robusta, and Arabica:Robusta (50:50)) and the proportion of coffee:fennel seed powders (i.e., 92:8, 90:10, and 88:12). Physicochemical and organoleptic quality parameters were analyzed. In all coffee types, the addition of fennel seed powder at different concentrations significantly affects the sensory attribute (i.e., color, taste, and aroma) and the physicochemical characteristics of Tengger herbal coffee. The blending of coffee with fennel seed powder improved the taste and aroma of the herbal coffee. The best formulation was obtained from A3B3, a mixture of 44% Arabica coffee: 44% Robusta coffee: 12% fennel seed powder. This formula resulted in Tengger herbal coffee with pH 4.9, 16.6 color lightness, 0.64% total insoluble solids (TIS), 0.07% caffeine content, 47.2 mg GAE/g total phenol, 0.49 ppm antioxidant activity (IC50), and 0.58% reducing sugar. The findings confirmed that Tengger herbal coffee offers health benefits from its antioxidant activity, alongside the potential as a traditional beverage product.

Authors: Liang Chen , Zhan Huaiyu , Li Bingyun , Fu Shiyu
Published: July 2023

The compositions of alkaline extractives in bamboo sulfonated chemi-mechanical pulps (SCMP) were analyzed by UV spectroscopy and gas chromatography-mass spectrometry (GC-MS), and their effects on peroxide bleaching were studied. The extractives were composed of short-chain aliphatic compounds, phenols, and fatty acids, of which phenols were the major components. The amount of extractives was increased with the dosage of NaOH, and correspondingly, the bleachability of the extracted pulp was improved. When 3.5% NaOH was used, the brightness gain was 5.83%ISO, and the post-color (PC) number was decreased by 55.7%. The phenol compounds, which might easily generate conjugated structures, may play an important role in bleachability of bamboo SCMP and brightness stability of pulp.
Cost reduction studies of decorative laminates

Published: July 2023

Barrier paper, which is made of bleached absorbent kraft pulp, is a significant layer of decorative laminates, since it controls the see-through of brown color of saturating kraft paper and its opacifying effect usually is achieved by a heavy loading of TiO2. The TiO2, due to its very small particle size, passes between the cellulosic fibers and drains into the white water. To overcome this problem, papermakers try to use various retention aids for improving overall retention of TiO2, but agglomeration of TiO2 causes a decrease in light scattering efficiency of TiO2. During the subsequent saturation operation, the air in the voids is replaced by melamine formaldehyde, which has a refractive index close to that of cellulose. As a result, the sheet becomes translucent and poses ‘see through’ problem. Keeping this in view, anhydrous magnesium silicate is used as an extender with TiO2 because it effectively increases the overall filler retention, sheet brightness, opacity. The dispersed aqueous slurry of anhydrous magnesium silicate forms fine gel that entraps TiO2 in the wet web and prevents removal of fines and fillers. The addition of 25% TiO2, 7% micronized soapstone powder, 8% anhydrous magnesium silicate, 1% melamine formaldehyde, and 0.1% sodium hexameta-phosphate was found to improve the overall retention by 65.25% and to cut the manufacturing cost by US$ 546.00 per tonne of pulp without affecting the product quality.

Published: July 2023

Composite membranes for dialysis were prepared by a Loeb-Sourirajan (L-S) phase inversion process. After adding nanocrystalline cellulose (NCC), the ultrafiltration coefficient of the dialysis membrane could reach 48.37 L•m-2•h-1•mmHg-1. The clearance of lysozyme and urea could reach 70.25 % and 90.38 %, respectively. Simultaneously, the retention ratio of BSA could remain over 96%. Afterwards, in order to judge the hydrophilic nature of the dialysis membrane, the contact angle and surface energy were tested and calculated. And then the tensile strength and elongation ratio were measured to reflect the mechanical properties. The membranes were also observed with transmission electron microscopy (TEM) and atomic force microscopy (AFM) to reveal the state of dispersion and dimensions of NCC. The porous structures of dialysis membrane were researched with both scanning electron microscopy (SEM) and AFM.
Adsorption of pitch and stickies on magnesium aluminum hydroxides treated at different temperatures
Authors: Li Guodong , Liu Wenxia
Published: July 2023

Magnesium aluminum hydroxides (MAH) of nitrate and carbonate forms were prepared by co-precipitation, dried at different temperatures, and employed as an adsorbent for pitch and stickies in papermaking. Results indicated that MAH that had been heat-treated had higher adsorption capacity to model pitch and stickies at neutral pH. Low-temperature-dried magnesium aluminum hydroxides of nitrate form (MAH-NO3) had higher adsorption capacity to model pitch and model stickies than those of the carbonate form (MAH-CO3). Increasing the drying temperature of MAH reduced the difference of adsorption capacity between MAH-NO3 and MAH-CO3. Higher-temperature-dried magnesium aluminum hydroxides also showed higher adsorption capacity to model pitch and stickies when the drying temperature was lower than 550 oC. MAH displayed higher adsorption capacity while a lower initial adsorption rate of model stickies than of model pitch. The model pitch and stickies were adsorbed on MAH significantly by charge neutralization and distributed mainly on the surface of the platelets of magnesium aluminum hydroxides. The experimental isothermal adsorption data of model pitch and stickies on MAH dried at 500 oC fit well to the Freundlich and Dubinin–Radushkevich isotherm equations.

Inequality in the Face of Death under Covid-19 in Ukraine
Authors: SHEVCHUK PAVLO
Published: July 2023

If there is a decline in mortality, it is mainly in younger age groups. As a result, more and more deaths are occurring in older age groups. In advanced societies, therefore, people are becoming “more equal in the face of death”. A sharp increase in mortality, such as that caused by the Covid-19 pandemic, affects different age groups of the population to different degrees. It is therefore relevant to study the change in inequality of life expectancy under the conditions of a sudden shock. The purpose of this paper is to analyse the inequality of lifespan variation in Ukraine in 2020—2021 and to compare it with countries with different levels of mortality. Previous studies of lifespan variation specifically devoted to Ukraine, or those that used data for Ukraine, were conducted or related to the pre-Covid period. The novelty of this work is the study of the behaviour of indicators characterising the inequality of lifespan before and during the two years of the epidemic, for which data are available. The demographic me t hod for constructing life tables and statistical methods for calculating lifespan variation indicators were used. Those are: Gini coefficient, average inter-individual difference in length of life, lifespan disparity, entropy of the life table, standard deviation of age at death, coefficient of variation. These indicators were calculated for the period 1989—2021 for Ukraine, Poland, Sweden, Spain, Japan, and England and Wales. It was confirmed that life expectancy is generally inversely related to inequality in the life table. It was found that this rule can be violated during mortality shocks such as the Covid-19 pandemic. It is shown that male life expectancy and lifespan inequality in Ukraine decreased in 2020—2021. Average inter-individual difference in length of life and lifespan disparity have decreased by 6.6—6.9 %. On the other hand, almost all indicators of inequality for women have increased. The life expectancy elasticity indicator (entropy of the life table) turned out to be the most sensitive, increasing to 4.9 %. At the same time, it is interesting to note that the standard deviation of age at death for women in Ukraine decreased by 1.8 %. The Covid-19 pandemic has affected inequality depending on sex and the country’s pre-Covid level. Inequality indicators in Japan have hardly changed. Inequality rates rose in Spain and Sweden before returning to their previous downward trend. Available data for England and Wales suggest a continued slow trend towards greater inequality.
Poverty of the Ukrainian Pensioners: Pre-War Situation and Influence of the War
Authors: POLІAKOVA SVITLANA , KOHATKO YURII
Published: July 2023

The purpose of the article is to determine the level of poverty among Ukrainian pensioners, assess deprivations, including those in different types of settlements, and forecast the impact of full-scale military actions on the increase in monetary poverty. Studying poverty among pensioners during wartime is very important, as retirement age is a time in life when a person can no longer ensure a stable income, except for their pension, and requires access to healthcare and various social services. Military actions in some parts of Ukraine make normal existence impossible and critically exacerbate the problem of poverty, while in other areas, they significantly increase the poverty level due to a general decline in the standard of living. Various methods are used to study poverty among pensioners in Ukraine, both specialized and general scientific methods. The monographic method, bibliometrics, and content analysis are used for preliminary study of the problem. The computational method, forecasting, and modeling are used to forecast the impact of full-scale military actions on the growth of monetary poverty. The scale of pre-war poverty levels among Ukrainian pensioners, including self-assessment, has been assessed. In 2021, 26.3 % of urban and 29.2 % of rural pensioner households were classified as poor according to the relative criterion. On average, 23.4 % of households across the country were classified as poor. The level of poverty has been determined based on deprivations. The poverty level based on deprivation indicators in different types of settlements (share of households experiencing 4 or more deprivations) in 2020 was 2.6 times higher in rural areas compared to the corresponding indicator in cities. Deprivations among Ukrainian pensioners have been assessed in terms of types of settlements. Forecasts for poverty among Ukrainian pensioners have been provided based on the absolute criterion of expenses below the actual subsistence minimum. According to the forecasts of experts from the Ptoukha Institute for Demography and Social Studies of the National Academy of Sciences of Ukraine, in 2023, the share of the population living on less than the actual subsistence minimum will increase by 1.7 times throughout the country, compared to 2021, and reach 67.8 %. Taking into account the fact that the poverty level among pensioners, especially older people, significantly exceeds the average indicators for the country from year to year, the majority of elderly people — 76.4 % in cities and 83 % in rural areas — will fall into the category of poor.

Water is considered as the working fluid of wet steam turbine units. The importance of a purposeful change in the thermophysical properties of water used for energy needs is indicated. A reagent-free method (transverse magnetic field of permanent magnets) of influence on water is proposed. Literature data on currently available papers dedicated to the study of water properties is presented. It is shown that the mechanisms of influence of external physical fields on the physicochemical and thermophysical properties of water have not been elucidated as of now. It is emphasized that the properties of distilled water during exposure and after exposure to physical fields are even less studied. The currently existing contradictions between theoretical ideas about the properties of water and experimental results are considered. It was found that currently there are no correct methods and equipment capable of indicating changes in water properties in real time. As a solution, the equipment and method of analyzing the optical density of distilled water is proposed. The shortcomings of most existing experimental works on the study of the influence of physical fields on the optical density of water are analyzed. The requirements for devices intended for measuring the optical density of distilled water are formulated. A stand was made and experimental work on the study of the dependence of the optical density of distilled water on the induction of a magnetic field that affects it was carried out. It is proved that the magnetic field affects the optical density of distilled water in the infrared range of wavelengths both in the direction of increase (4.1%) and in the direction of decrease (1.7%) depending on the induction of the magnetic field and the speed of water flow through the working section of magnetization device. A hypothesis explaining the obtained result is proposed.

Gastrointestinal complications of cystic fibrosis (CF) are often the earliest manifestations of disease and contribute to significant morbidity and mortality. Early diagnosis of CF is paramount, as early intervention has been associated with improved long-term pulmonary and nutritional outcomes. In this review, we describe common gastrointestinal, pancreatic, hepatic, and nutritional manifestations of CF in neonates to aid clinicians in diagnosing and managing the earliest gastrointestinal manifestations of CF. Furthermore, we discuss how the use of CFTR-targeted therapies by pregnant and/or breastfeeding persons may affect CF diagnosis in newborns and their potential impact on halting or reversing CF disease progression.
Pediatric Intestinal Transplantation Management and Outcomes

Published: July 2023

Intestinal failure is the anatomic or functional loss of intestinal function below the minimum required to absorb nutrients to maintain health and growth. Parenteral nutrition is the main supportive therapy for children with intestinal failure, but if serious complications develop, intestinal transplantation may be needed to sustain life. Referral to a multidisciplinary intestinal rehabilitation team and an extensive evaluation are necessary steps before listing for transplantation. Immunosuppression is part of life-long therapy after transplantation, and children continue to have high medical needs. Serious complications include acute cellular rejection, graft-versus-host disease, infection, and post-transplant lymphoproliferative disease. However, intestinal transplantation has led to improved outcomes in recent years and is a viable life-saving option for many children with intestinal failure.
Sickle Cell Crises in Pregnancy: Fetal and Neonatal Implications
Authors: Cole Ashley Appiagyei , Wagner Stephen M. , Gupta Megha
Published: July 2023

Sickle cell disease (SCD) is the most common inherited condition worldwide. In the United States, SCD affects 100,000 births every year, mostly persons of African descent. In SCD, red blood cells assume a sickle shape when deoxygenated. This leads to the occlusion of small blood vessels and decreased oxygenated blood flow, resulting in ischemic and thrombotic injury to various organs, which further leads to organ dysfunction. In pregnancy, patients with SCD are at an increased risk of vaso-occlusive crises, which further increases the risks of maternal, fetal, and neonatal morbidity and mortality.

OBJECTIVES

Access to readily available, reliable, and easy-to-use coronavirus disease 2019 (COVID-19) tests remains critical, despite great vaccination progress. Universal back-to-school testing offered at early care and education ([ECE]; ie, preschool) sites to screen for positive cases may help preschoolers safely return to, and stay in, ECE. We examined the acceptability and feasibility of using a quantitative polymerase chain reaction COVID-19 saliva test for young children (n = 227, 54.0% girls: mean age = 52.3 ± 8.1 months) and their caregivers (n = 70 teachers: mean = 36.6 ± 14.7 years; n = 227 parents: mean = 35.5 ± 9.1 years) to mitigate the spread of COVID-19 and reduce days of school and work missed for households with children who test positive.

METHODS

Participants were recruited at ECE sites serving low-income communities as part of the Rapid Acceleration of Diagnostic Testing–Underserved Populations Back to Early Care and Education Safely with Sustainability via Active Garden Education project (NCT05178290).

RESULTS

Surveys in English or Spanish administered at testing events to children and caregivers at ECE sites showed child and adult acceptability and feasibility ratings were generally high. More favorable child and parent ratings were positively associated with child age and whether the child was able to produce a saliva sample. Language preference was not associated with any outcomes.

CONCLUSIONS

Saliva sampling for COVID-19 at ECE sites is an acceptable strategy as an additional layer of protection for 4- and 5-year-olds; however, alternate testing strategies may be needed for younger children.

OBJECTIVES

Equitable access to coronavirus 2019 (COVID-19) screening is important to reduce transmission and maintain in-person learning for middle school communities, particularly in disadvantaged schools. Rapid antigen testing, and at-home testing in particular, could offer substantial advantages over onsite testing from a school district’s perspective, but it is unknown if engagement in at-home testing can be initiated and sustained. We hypothesized that an at-home COVID-19 school testing program would be noninferior to an onsite school COVID-19 testing program with regard to school participation rates and adherence to a weekly screening testing schedule.

METHODS

We enrolled 3 middle schools within a large, predominantly Latinx-serving, independent school district into a noninferiority trial from October 2021 to March 2022. Two schools were randomized to onsite and 1 school to at-home COVID-19 testing programs. All students and staff were eligible to participate.

RESULTS

Over the 21-week trial, at-home weekly screening testing participation rates were not inferior to onsite testing. Similarly, adherence to the weekly testing schedule was not inferior in the at-home arm. Participants in the at-home testing arm were able to test more consistently during and before returning from school breaks than those in the onsite arm.

CONCLUSIONS

Results support the noninferiority of at-home testing versus onsite testing both in terms of participation in testing and adherence to weekly testing. Implementation of at-home COVID-19 screening testing should be part of schools’ routine COVID-19 prevention efforts nationwide; however, adequate support is essential to ensure participation and persistence in regular at-home testing.

Electrolyte disorders are very common in the pediatric population. Derangements in serum sodium and potassium concentrations are among the most frequently seen given the risk factors and comorbidities unique to children. Pediatricians, in both outpatient and inpatient settings, should be comfortable with the evaluation and initial treatment of disturbances in these electrolyte concentrations. However, to evaluate and treat a child with abnormal serum concentrations of sodium or potassium, it is critical to understand the regulatory physiology that governs osmotic homeostasis and potassium regulation in the body. Comprehension of these basic physiologic processes will allow the provider to uncover the underlying pathology of these electrolyte disturbances and devise an appropriate and safe treatment plan.

O presente artigo tem como objetivo geral demonstrar a importância da dimensão étnico-racial na área da habitação, enfatizando os fenômenos socioespaciais atuais, com foco na seletividade socioterritorial. Para tal, utiliza-se de ampla revisão de literatura fundamentada no materialismo histórico e dialético em Marx, bem como nas análises sobre território e espaço de Milton Santos. Assim, evidenciando as motivações deste recorte fazer-se fundamental na área a partir de um resgate histórico sobre a formação socioespacial do espaço urbano no Brasil, tornando notória a consequente seletividade socioterritorial existente nos dias atuais. A partir da contextualização histórica, as ocupações irregulares são tidas como um reflexo desta questão e as Zonas Especiais de Interesse Social (ZEIS) tornam-se um importante suporte na garantia de moradia adequada à população de baixa renda; porém, ainda um tanto ineficazes sem um olhar atento para quem são os usuários das políticas e serviços ali presentes. Ademais, se fomenta o debate sobre a dimensão étnico racial precisar estar presente desde a formação acadêmica, visto que atualmente o conteúdo referente a temática é escasso ou quase nulo.
La extorsión frente al robo con violencia en las personas y su modalidad agravada por uso de armas: una primera aproximación
Authors: Salas Manuel Rojas

Los tipos penales del robo simple con violencia sobre las personas y su modalidad agravada comparten elementos comunes con el tipo penal de la extorsión, lo que podría llevar a confusiones prácticas en su aplicación, cuando en la realidad se trata de figuras absolutamente independientes entre sí, lo que puede derivarse claramente de la estructura misma de los tipos penales.

This study investigates the relationship between tourist satisfaction, destination image, and tourist loyalty. A descriptive correlational study was used as the research methodology, with destination image as the independent variable, tourist satisfaction as the mediating variable, and tourist loyalty as the dependent variable. The data was taken from domestic tourists visiting Jakarta, with a total sample of 280 people. Structural Equation Modelling with Smart PLS. was used to analyse the data. The findings revealed a significant positive correlation between city image and tourist loyalty, city image and tourist satisfaction, and tourist satisfaction with tourist loyalty. The relationship between city image and tourist loyalty is also mediated by tourist satisfaction. The higher the value of the city's image, the more satisfied and loyal the tourists to the city. Based on the findings of the study, theoretical and managerial implications are provided, and recommendations for further study are made.
