Published: August 2022

Objectives:

Tooth decay is an irreversible complication of calcified tooth tissues that is characterized by demineralization of the inorganic part and destruction of organic matter in the tooth and often leads to the formation of cavities. In the present study, we investigated the antibacterial effect of zinc nanoparticles (ZnNPs) green synthesized with Lavandula vera DC. by microwave method on Streptococcus mutans and Actinomyces viscosus compared with chlorhexidine.

Material and Methods:

ZnNPs were green synthesized using L. vera extract using the microwave and were characterized by scanning electron microscope, X-ray diffraction technique, nano-sizer-zetacizer, and Fourier-transform infrared spectroscopy. Antibacterial effects were evaluated through determining the minimum inhibitory concentration (MIC) of ZnNPs in comparison with chlorhexidine on standard strains of S. mutans and A. viscosus, by microbroth dilution method according to Clinical and Laboratory Standards Institute guidelines.

Results:

The absorption peak of ZnNPs was in the range of 230–330 nm. The size of ZnNPs varied from 30 to 80 nm, while most nanoparticles were between 50 and 60 nm. The best MIC related to ZnNPs + chlorhexidine was reported with 1.66 and 1.66 μg/ml for S. mutans and A. viscosus, respectively. Furthermore, the lowest MICs related to ZnNPs alone were obtained with 13.33 and 16.33 μg/ml for S. mutans and A. viscosus, respectively. ZnNPs + chlorhexidine in comparison with chlorhexidine had a significant (P < 0.05) antibacterial effect and inhibited the growth of both bacteria.

Conclusion:

ZnNPs especially combined with chlorhexidine exhibited promising antibacterial effect in comparison with chlorhexidine alone. However, further studies are needed to clarify the accurate mechanisms and toxicity of ZnNPs.

Tankyrases are multifunctional polymerases proteins that regulate numerous cellular processes including Wnt signaling, telomere maintenance and tumor suppressors. Therefore, tankyrases are characterized to be an effective target for the management of numerous cancers. Despite the number of available inhibitors, the on-target intestinal toxicity serves as the major challenge in developing new drugs against TNKS1 protein. Considering the same, in the present study, an effort has been made to identify novel and potent inhibitors from the NPACT library by employing various computational approaches. The results from our analysis revealed that obovaten and duartin exhibit a higher docking and binding energy score than the reference (XAV939) molecule. Further, post-processing analysis by PCA and FEL studies also concluded that these hit molecules strongly bind to the TNKS1 protein. In essence, the inhibitory activity of these molecule was validated across 77 colorectal cancer cell lines by employing a deep neural network algorithm. Taken together, our study uncovers natural compounds obovaten and duartin as possible drug candidates for the treatment of cancer through TNKS1 inhibition.

Published: August 2022

Synthesis of nanoparticles through plant-based products which are eco-friendly and safer, can be used for various purposes such as environmental, biomedical and antibacterial applications. The present work deals with an environmentally benign process for the synthesis of TiO2 nanoparticles using Butea monosperma and Woodfordia fruticosa plants. Synthesized TiO2 nanoparticles using whole-plant extract were characterized using UV-VIS, FTIR, XRD and SEM analysis. The appearance of a characteristic vibrational mode of TiO2 in the range of 880 and 450 cm-1 confirmed the synthesis of nanoparticles. In the case of UV-VIS analysis, a red shift was observed in the band position as the calcination temperature was increased. XRD and SEM analysis helped in determining crystalline phase and morphology respectively.

Authors: Nirmala S. , Kumaraguru N.
Published: August 2022

This work focused on studying the adsorption of Cu(II) from aqueous solutions by acid activated carbon prepared from Centella asiatica (CA) leaves. Under batch mode, the performance of activated CA in the removal of Cu2+ ions is assessed with a focus on operational parameters such as pH (2 to 9), activated CA dose (25 to 150 mg/g), initial Cu2+ ions concentration (10 to 50mg/L), contact time (10 to 90min) and temperature (30 to 60°C). Adsorption data are tested with isotherms (Langmuir and Freundlich) and kinetic models (pseudo-first order and pseudosecond order). Thermodynamic parameters (ΔGo, ΔHo and ΔSo) are computed. The following results are optimized under batch mode: initial concentration of 10 mg/L, activated CA dose of 100 mg/L, contact time of 90 min, pH of 6 and temperature of 300C. The adsorption isotherm fits well with Langmuir model. The adsorption is well controlled by the pseudo-second order. The computed thermodynamic parameters signified the reaction process’s feasibility, endothermicity, spontaneity and physisorption. The results show that activated CA can effectively remove Cu2+ ions from aqueous solutions.

Published: August 2022

Integrating carbon dioxide (CO2) electrolysis with CO2 capture provides exciting new opportunities for energy reductions by simultaneously removing the energy-demanding regeneration step in CO2 capture and avoiding critical issues faced by CO2 gas-fed electrolysers. However, understanding the potential energy advantages of an integrated process is not straightforward due to the interconnected processes which require knowledge of both capture and electrochemical conversion processes. Here, we identify the upper limits of the integrated process from an energy perspective by comparing the working principles and performance of integrated and sequential approaches. Our high-level energy analyses unveil that an integrated electrolyser must show similar performance to the gas-fed electrolyser to ensure an energy benefit of up to 44% versus the sequential route. However, such energy benefits diminish if future gas-fed electrolysers resolve the CO2 utilisation issue and if an integrated electrolyser shows lower conversion efficiencies than the gas-fed system.

Structurally ordered L10-PtM (M = Fe, Co, Ni, etc) intermetallic nanocrystals (iNCs), benefiting from the chemically ordered structure and higher stability, are one of the best electrocatalysts used for PEMFC. However, their practical development is greatly plagued by the challenge that high-temperature annealing (> 700 °C) has to be used for realizing disorder-order phase transition (DOPT) due to the high activation barrier (Ea), which always leads to severe particle sintering, morphology change, and makes it highly challenging for gram-scale preparation of desirable PtM iNCs. Here, we report a general low-melting-point metal induced bond strength weakening strategy to promote DOPT of PtM (M = Ni, Fe, Cu, Zn) alloy catalysts. We demonstrate that the introduction of Sn can reduce DOPT temperature to a record-low temperature (≤ 450 °C), which enables ten-gram-scale preparation of high-performance L10-PtM iNCs. X-ray spectroscopic studies, in-situ electron microscopy and theoretical calculations reveal that the Sn-facilitated DOPT mechanism at record-low temperature involves the weakened bond strength and reduced Ea via Sn doping, the formation and fast diffusion of low coordinated surface free atom, and subsequent L10 nucleation. Most importantly, the 15% Sn-doped L10-PtNi iNCs display outstanding performance in H2-air fuel cells with a high peak power density of 1.45 W cm-2 for Pt alloy catalysts and less than 25% activity loss after 30000 cycles at a quite low cathode Pt loading amount of 0.12 mg¬Pt cm-2, representing as one of the most efficient cathodic electrocatalyst for PEMFCs.

The catalytic activity of multifunctional microporous materials is directly linked to the spatial arrangement of their struc-tural building blocks. Despite great achievements in the design and use of isolated catalytic sites within such materials, the precise determination of their atomic-level structure and their local environment still remains a fundamental chal-lenge, especially when they are hosted in non-crystalline solids. Here, we show that by combining NMR measurements with pair distribution function (PDF) analysis and computational chemistry, a very accurate picture of the organometallic Cp*Rh catalytic sites inside the cavity of porous organic polymers can be determined. Two microporous supports based on bipyridine and biphenyl motifs functionalized with NH2 or NO2 groups were considered. Making use of differential PDF, Dynamic Nuclear Polarization (DNP) enhanced solid-state NMR spectroscopy on 15N labelled–NH2 and –NO2 materi-als, and 129Xe NMR, the detailed structure of the heterogenized organometallic complex and its confinement within the amorphous porous organic polymers is revealed with a precision of 0.1 Å, fully matched by the computed models. While the same well-defined molecular structure is observed for the organometallic catalyst independently of the functionalisa-tion of the porous organic polymer, subtle changes are detected in the average ligand-pore wall distance and interactions in the two materials.

Accelerating catalytic chemistry and tuning surface reactions requires precise control of the electron density of metal atoms. In this work, nanoclusters of platinum were supported on a graphene sheet within a catalytic condenser device that facilitated electron or hole accumulation in the platinum active sites with negative or positive applied potential, respectively. The catalytic condenser was fabricated by depositing on top of a p-type Si wafer an amorphous HfO2 dielectric (70 nm), on which was placed the active layer of 2-4 nm platinum nanoclusters on graphene. Potential of +/-6V applied to the Pt/graphene layer relative to the silicon electrode moved electrons into or out of the active sites of Pt, attaining charge densities more than 1% of an electron or hole per surface Pt atom. At a level of charge condensation of 1-10% of an electron per surface atom, the binding energy of carbon monoxide adsorbed to a Pt(111) surface was computed via density functional theory to vary from 5 to 48 kJ/mol (0.05-0.50 eV), consistent with the range of carbon monoxide binding energies determined from temperature programmed desorption (ΔBE,CO of 20±1 kJ/mol or 0.19 eV) and equilibrium surface coverage measurements (ΔBE,CO of 14±1 kJ/mol or 0.14 eV). Impedance spectroscopy indicated that Pt/graphene condensers with potentials oscillating at 3,000 Hz exhibited negligible loss in capacitance and charge accumulation, enabling programmable surface conditions at amplitudes and frequencies necessary to achieve catalytic resonance.

En este trabajo se presenta una estrategia de gestión de la energía (EMS) basada en reglas como parte de un proyecto de investigación que busca la inclusión de fuentes híbridas en bicicletas de pedaleo asistido (BPA). Para su concepción y desarrollo se considera la densidad de energía y la densidad de potencia de las fuentes existentes con base en el diagrama de Ragone, con el fin de optimizar y mitigar la degradación de estas, aumentando su vida útil y minimizando los costos económicos de su uso en diferentes perfiles de velocidad. La EMS desarrollada es simple, intuitiva y fácil de implementar en diferentes vehículos eléctricos híbridos (HEV), consta de tres EMS locales para las fuentes disponibles evaluadas por simulación utilizando un modelo propuesto en la literatura. En este caso de estudio se optimiza el uso de las fuentes de energía en un laboratorio modular-móvil (ECCE), el cual es utilizado para evaluar bajo condiciones reales los componentes eléctricos de vehículos eléctricos híbridos. El ECCE tomado como referente se compone de una pila de combustible, supercondensadores, un paquete de baterías de plomo y un sistema de frenado regenerativo. Componentes similares a los del ECCE pueden conformar una fuente híbrida para BPA y de esa forma aumentar su autonomía. Lo anterior permitiría ampliar las ventajas de una BPA como alternativa de transporte incluso para grandes distancias y topografías quebradas. El proyecto permitirá una mayor apropiación de tecnologías emergentes orientadas hacia la mitigación de la contaminación ambiental y la lucha contra elcambio climático. Con la EMS propuesta se logra minimizar costos de operación de un HEV mediante un despacho económico combinado con toma de decisiones técnicas basadas en reglas, para de esa manera darles un mejor aprovechamiento a las fuentes.

Published: August 2022

Los crecientes desastres naturales en todo el mundo han venido generando pérdidas económicas, ambientales y humanas. En este artículo se presenta un análisis preliminar, con herramientas computacionales, de series históricas de la cuenca alta del Río Caquetá, tanto de caudales IDEAM como de precipitación ERA5. La mitigación de inundaciones debe ir de la mano con la mitigación de las sequías, debido a que si se conocen los regímenes históricos de lluvias mensuales y sus cantidades, se pueden establecer sistemas de embalses que sirvan de infraestructura para la producción agropecuaria y que, al mismo tiempo, promuevan la infiltración en la cuenca alta, de manera que se aumente la infiltración en los acuíferos al máximo para mitigar así los fenómenos de inundación y sequía, al tiempo que se generan procesos productivos sostenibles. Para ello, la primera aproximación debe iniciarse con el análisis de datos mediante herramientas computacionales. En este caso, se empleó la herramienta computacional WEAP, utilizando, como datos de entrada, los datos de reanálisis ERA5 en cuanto a datos de lluvia, para obtener un histórico de lo sucedido en la cuenca en esta ventana temporal y para los datos de caudal los datos del IDEAM.

Collaborative strategies and museum practice: An inquiry into the concept of relationships as social capital for Aotearoa New Zealand museums
Authors:   , De Stefani Samuele
Published: August 2022

This dissertation is about the relational dimension of Aotearoa New Zealand museums. Borrowing concepts from social and organisational studies, it investigates why and how New Zealand museums are leveraging relationships, partnerships, and other forms of cooperation to expand their reach, engage audiences and communities, collect and share material and symbolic resources, and increase participation. The urgency of the research stems from the most recent debate in several fields of academic study: that contemporary society appears as an increasingly interconnected context in which organisations are required to play an active role and strategically use their networks to build social capital. In this scenario, museums must abandon their insularity in favour of a more holistic approach towards their external environment to achieve their social, economic, and cultural goals.

The study explores diverse forms of collaboration initiated within the sector. Collaborative strategies are interpreted and contextualised within the New Zealand museum sector to understand historical influences, current challenges, expected outcomes, potential applications and future innovations. The research methods employed hereafter to answer the research questions reflect such complexity: a literature review, document analysis, interviews with museum staff, and a sector survey have been used to collect data. The purpose was to understand current thinking about museum relationships and decipher narratives, values, and challenges connected with collaborations.

The idea of the museum that emerges from the findings sheds new light on the social role of cultural organisations and aims to stimulate further research on relational museology. A conceptual framework for the critical interpretation of relationships called the ‘Relational Wind Rose’ is proposed at the end of this dissertation, offering professional museum staff a practical tool to conduct stakeholder analysis. The Relational Wind Rose could also help museums identify opportunities, mitigate risks, and manage challenges inscribed in their networks. Relationship management is becoming a vital skill for museum staff.
Teaching Applied Piano Singing While Playing Based on Xindi Applied Piano Pedagogy: Taking Fujian Vocational College of Art as an Example
Authors: Luo Yan , Yang Hongmei
Published: August 2022

As known to all, China has witnessed remarkable development in addition to its effective implementation of the “double reduction” policy. Under such circumstance, the piano has drawn more interest and parental affection as a vital course that may improve students’ all-round qualities. While piano education is gaining momentum, the country has raised the requirements for the piano teacher workforce in terms of their professional qualities. Under the background of promoting quality-oriented education nationwide, piano education in Chinese vocational colleges of art has garnered more attention. In contrast to applied piano instruction, which has received wide recognition and promotion, the traditional elite private teaching model targeted at nurturing pianists has more than ever failed to meet societal demands. The majority of graduates from vocational colleges of art seem to be unable to apply what they have learned. They are unable to compose accompaniment for simple songs, write piano music, provide piano accompaniment for singers, or sing while playing the piano. As a result, they fall short of living up to the expectations of piano teaching and meeting the needs of music teacher employment in primary and secondary schools. The development of “Xindi Applied Piano Pedagogy” can effectively address the aforementioned problems. As piano teachers, the authors experimented with Xindi Applied Piano Pedagogy to teach singing while playing the piano to first-year students at Fujian Vocational College of Art. A measurement table was used to measure the differences in various musical abilities of those students after the experiment, statistical analysis of the data was performed, and the preliminary results were obtained. The results showed that training in Applied Piano Singing while Playing led to a noticeable improvement in students’ musical literacy, harmonic hearing, singing while playing beloved songs, and other abilities. Xindi Applied Piano Pedagogy is guided by the philosophy of talent cultivation, featuring “application, theories, and practice.” It can be tailored to different students, so that they can indeed apply what they have learned and enhance their practical and innovative capabilities.

Published: August 2022

The purpose of the study was to evaluate the effectiveness of low-intensity laser radiation in the complex treatment of trophic ulcers of the lower extremities in patients with varicose veins based on objective criteria. Materials and methods. Clinical and histomorphological studies were performed on patients aged 15 to 75 years who were treated for small and medium stage II ulcers on the lower extremities at the Training and Surgical Clinic of the Azerbaijan Medical University and the Central Hospital of the Gazakh region. The criteria for inclusion in the study were men and women of the above mentioned age, and the presence of ulcerative necrotic lesions of the lower extremities. The exclusion criteria were heart failure, systemic diseases, oncological diseases, hormone therapy, and pregnancy. The patients included in the study groups were comparable in age and sex characteristics, the volume of ulcerative lesions of the lower extremities, the duration of the disease and the somatic state. In the main group, in the treatment of trophic ulcers of the lower extremities of small and medium sizes, Venocoryl ointment, low-intensity laser radiation and endovenous laser ablation using a modified ptfe-coated cylindrical light guide were used. The control group included 25 patients, in whose regional treatment only standard retro-specific methods of treatment using endovenous laser ablation were used. The comparison group included 25 patients who underwent endovenous laser ablation and were prescribed Venocoryl ointment. The experimental groups included 21 men and 54 women aged 15 to 75 years. Results and discussion. The rate of healing of trophic ulcerative wounds during the second month after the start of therapy in the main group in patients of the main group was 0.131 ± 0.008 cm2 per day, in the comparison group – 0.125 ± 0.007 cm2; in the control group – 0.072 ± 0.004 cm2 per day. When observing patients for up to 6 months, the following was noted: in the main group, after the application of the laser, it was possible to completely heal the wound defect in 21 patients (84%) in the main group, 17 patients in the comparison group (68%) and 13 patients in the control group (52%). In the course of the research, it was found that in the main group for the first month there is an active process of epithelization and a reduction, against this background, of the ulcer, and, despite the decrease in the rate of reparative processes in this group, the ulcer epithelializes much earlier and faster. Conclusion. The high rate of healing with the use of laser radiation, compared with standard treatment, was maintained throughout the study period

Published: August 2022

The purpose of the work was to study the epidemiological aspects of arbovirus infections in the southeastern part of Azerbaijan using serological studies and questionnaires using forms developed by us. Materials and methods. The study involved 633 residents of the southeastern part of Azerbaijan (Lankaran, Masally districts, the territory of the Qizil-Aghaj State Reserve), who underwent a serological survey on a voluntary basis. Results and discussion. Seropositive were 15.3 ± 1.4% of the examined. 6 types of arbovirus infections have been identified – West Nile Fever, Sindbis, Tahyna, Batai, Uukuniemi and Bhanja. The dominant types of arboviruses were Sindbis and Tahyna, the detection rate of which is 30.5 ± 4.5 and 26.2 ± 4.4%, respectively (χ2=0.56; P>0.05), detection of other types did not exceed 10.4 ± 2.9% (χ2=9.21; Р<0.01). The level of seropositivity depended on the condition of the residents at the time of blood sampling. Comparative evaluation of the identified symptoms in seropositive residents and their interpretation allows to identify risk groups, which is advisable for reducing serological studies and identifying seropositive patients more targetedly. It has been established that the most effective infection occurs in May–June and September–October, when the activity of mosquitoes and the density of their settlement in residential premises and other biotopes in the human habitat is the highest. Conclusion. The study of the seasonality of infection of residents with arbovirus in epidemiological terms is very important, as it allows planning and implementing appropriate preventive measures. Based on the data obtained, it can be argued that the most effective infection of residents occurs in May–June and September–October, when the activity of mosquitoes and their density in residential premises and other biotopes in the habitat of residents is the highest. Infection can also occur in summer, late autumn and early spring, but it is not very effective.

The purpose of the study was to highlight the experience of training specialists in the specialty «Nursing» in the conditions of distance education using telecommunication systems. Materials and methods. Based on the analysis of literary sources, educational programs and pedagogical experience of the department of general medicine with the course of physical therapy of Oles Honchar Dnipro National University, we highlight the peculiarities of the training of specialists in the specialty «Nursing» in the conditions of distance education using telecommunication systems. Results and discussion. The modern development of Ukraine is characterized by a gradual increase in the demand for higher medical education. Today, education is perceived as a strategic commodity and a force of society, which prompts Ukrainian universities to respond to changes, ensuring their existence and development in the conditions of globalization. In connection with the above, the problem of the quality of higher education in remote conditions is gaining the greatest relevance at the current stage of the development of society. A feature of today's medical education is that not only doctors but also nurses have the opportunity to obtain higher education. Today, a nurse is not only a specialist who provides patient care and is an «assistant» to a doctor but a modern nurse is considered a manager and leader of the relevant work in a medical institution. To date, educational and scientific programs in the specialty «Nursing» determine the need to ensure the training of highly qualified specialists capable of implementing the medical and diagnostic process, care and guardianship of patients in health care institutions of various profiles and at home; organization and management of the work of nursing structural units; implementation of the educational process at universities and institutions of postgraduate education, as well as scientific research on nursing problems. The tasks of the educational program are formed on the basis of today's challenges and fully meet the needs of society and the interests of potential employers. Conclusion. The latest educational technologies in the professional training of specialists in the specialty «Nursing» in the conditions of distance education with the use of telecommunication systems should be aimed at the most informative teaching of material and effective conducting of practical classes, which ensures the improvement of the quality of education, the maximum development of individual creative abilities and the adaptation of education to modern requirements, which ultimately leads to a high level of training of future nursing specialists

The purpose of the study is to examine the impact of rehabilitation fitness on the physical condition of women with musculoskeletal disorders. Materials and methods. The study was held on the basis of the fitness club "LIGA" in Lviv and was attended by 65 women of the first mature age with musculoskeletal disorders. The methods used were: theoretical analysis and generalization of data from scientific and methodological literature; pedagogical observation; sociological method; pedagogical testing; pedagogical experiment; medical and biological methods; methods of mathematical statistics. Results and discussion. As the survey showed female fitness club visitors pay attention to the study of various aspects of leading a healthy lifestyle. The main sources of informing women about the need for health-improving classes for most women (47.2%) were friends and 27.0% of people received information from the Internet. Strength fitness is preferred by 62.0% of people. 22.3% of women preferred cyclic kinds of physical activities. Dance fitness programs attract 8.9% of respondents. Further research was aimed at studying the impact of rehabilitative fitness classes on women's health. 21 women who had osteochondrosis and consented to participate in the study were involved in the pedagogical experiment. The program of rehabilitation fitness classes was developed taking into account the recommendations of specialists and was aimed at restoring the functional state of the spine and preventing recurrence of the disease. In addition, women were offered individual recommendations for daily water intake, a balanced diet and daily routine. Conclusion. It was found that 68.8% of women surveyed are interested both in information about general health and health promotion and leisure activities; 22.6% of women are interested in the features of certain types of health activities; 12.9% of people would like to learn about the possibilities of non-traditional remedies and 1.1% are not interested in healthy living. It is determined that after the use of rehabilitation fitness classes the number of persons with below average level decreased by 19.1%; the number of women with an average level of physical condition increased by 23.8% and the number of persons with above-average level increased by 4.8%. However, women with low and high level of physical condition were not detected. It was found that the percentage of fat in women before the pedagogical experiment was 22.98 ± 6.37%, while after three months of training its rate was 20.24 ± 5.79%. There was an improvement of this indicator by 11.9%. In terms of weight, it decreased by 2.13 kg

The aim of this study is to propose a model of stability and sensitivity for the studies used in the implementation of multi-criteria decision making (MCDM). In this context, it is proposed to use the steps "sensitivity analysis based on the variation of criterion weight, sensitivity analysis based on sequence reversal feature and comparison analysis with results from different sorting methods" for stability and sensitivity analysis. In the implementation part of the method, the Fragile Five countries were used as criteria for the unemployment rate, state budget, GDP growth, inflation, current account balance, risk premium for these countries. The criteria were weighted with MEREC and the ordering of alternatives was carried out with WISP. In the application phase of the method, it was found that the model was sensitive to changes in weight coefficients with different weights assigned to criteria over 22 scenarios. It has been observed that the model provides valid results in a dynamic environment through 4 different scenarios created in the sequence inversion step of the model. For the reliability of the MEREC-WISP-based model, a ranking comparison was made with some commonly used methods such as PIV, CoCoSo, COPRAS, WEDBA, TOPSIS and SAW and the results were found to have a high correlation.
Dijital Hizmetlerin Vergilendirilmesi ve Seçilmiş Ülke Uygulamaları

İnternet, bilgisayar ve mobil cihazlarının kullanımının gündelik hayatın bir parçası olmasının sonucu olarak dijital ortamlarda pazarlama ve satış faaliyetlerinin de buraya taşınması söz konusu olmuştur. Kamu kurumları, özel şirketler ve bireyler, internet mecralarında çeşitli mal ve hizmet alımını gerçekleştirmeye başlamış, bu durum ülkesel sınırları ortadan kaldıran küresel bir ekonomi oluşmasını da beraberinde getirmiştir. Dijital ekonomide de geleneksel ekonomi gibi çeşitli unsurlar bulunmaktadır ki dijital hizmet de bunlardan biridir. Bankacılık işlemleri, güvenlik işlemleri, rezervasyon, tur satışı, bilirkişi uygulamaları, reklam gibi pek çok hizmet bugün dijital ortamda verilebilir hale gelmiş, bu durum hizmet satışında vergilendirme konusunu da gündeme taşımıştır. İnternet ortamında özellikle hizmet satışının fiziksellikten uzak olması, ülkelerin sınırları dışında gerçek ve tüzel kişilerin işlem yapabiliyor olması, para transferlerinin belirsizleşmesi ve ödemelerin artık geleneksel para yollama yöntemleri ile yapılmaması, vergilendirme konusunda sorunlar oluşturmaktadır. Bu nedenle, vergi problemlerini çözmek için ülke yönetimleri birlikte hareket etmek ve küresel kurallar oluşturmak durumunda kalmışlardır. İktisadi İşbirliği ve Gelişme Teşkilatı (OECD) ve 20’ler Grubu (G20) ülkeleri başta olmak üzere, Amerika Birleşik Devletleri (ABD) ve Avrupa Birliği (AB) içerisinde tüm ülkelere rehberlik edecek olan genel vergilendirme ilkeleri belirlenmiştir ve ülkeler de bu ilkelere bağlı olarak mevzuatlarını oluşturmuşlardır. Bu çalışmada, ülkemizde ve dünyada hemen hemen aynı tarihlerde uygulamaya konan dijital hizmet vergilendirmesinin ne olduğu ve seçili ülkelerde uygulamaların nasıl gerçekleştirildiği sorusunun cevabı aranmıştır. Araştırma sonucunda, dijital hizmet vergisinin farklı ülkelerdeki uygulamalar benzerlik göstermektedir, fakat belirlenen vergi oranlarında ayrışmaktadır.
