Authors: Ivanišević Marko , Savić Stevan , Trbić Goran , Gvozden-Sliško Dijana
Published: September 2024

The thermal characteristics of urban areas differ from the thermal characteristics of the surroundings. The phenomenon of urban heat islands exists both in large urban areas and in smaller medium-sized areas. In the research of urban heat islands, there are two main approaches - direct measurements of air temperature in the field and reading temperatures from remote sensing products. In this study, remote sensing products from Landsat 8 and Landsat 9 missions were analyzed to determine differences in thermal characteristics of specific land use types within the territory of the city of Banja Luka. A total of 23 satellite images from various months of 2023 were collected, and the thermal characteristics were analyzed using an image from July. Considering the terrain's relief complexity in the observed area, the analysis also included the aspect of elevation levels. The research results indicate that built-up areas generally have higher temperatures compared to other land use classes by at least 2°C. The lowest average temperatures were observed in forest and water surface classes. Looking at elevation zones, the highest average temperatures were recorded in the first elevation zone up to 200 meters above sea level, reaching 30.4°C. All analyses were conducted using open-source software packages. The findings of this research can be beneficial for various sectors such as spatial/urban planning, health, energy, water management, forestry, and similar fields. Additionally, the research results can contribute to future detailed studies focusing on defining local climate zones and thermal variations within them.
SMaRT-mobile-BioMeteoS a mobile biometeorological station designed for the real time monitoring of heat stress
Authors: Pecelj Milica
Published: September 2024

Urban areas are increasingly challenged by rising temperatures, demanding adaptive measures to strenghten community resilience. With hotter summers and more frequent, severe heatwaves, managing exposure to extreme heat has become a critical issue. The concept of "resilient cities" aims to mitigate the negative impact of extreme heat and air pollution. A key requirement for effective mitigation is the heat stress assessment. Currently, Belgrade, the largest urban area in region, lacks direct monitoring of micrometeorological conditions. This gap means there is limited spatial insight into heat stress and thermal comfort distribution. Real-time micrometeorological monitoring is essential for improving heat exposure assessment. This paper introduces mini smart mobile biometeorological station (sMaRT-mobile-BioMeteoS), a device that combines meteorological and air quality sensors to monitor heat stress, thermal comfort, and air pollution in urban environments.
Memento Milutin Milanković
Authors: Pecelj Milovan , Pecelj Milica
Published: September 2024

Milutin Milanković persevered for more than fifty years before his theory on insolation was validated by the CLIMAP research project in 1976, led by James Hays, John Imbrie, and Nicholas Shackleton, which illuminated Earth's paleoclimatic history and resolved the mystery of ice ages. Despite enduring decades of skepticism and challenges to his theory, Milanković remained steadfast in his focus on understanding past climate dynamics linked to ice age occurrences. Early in his career, geographer Pavle Vujović played a crucial role in encouraging Milanković's ideas, introducing him to the works of influential meteorologists and climatologists like Hahn and Trabert. Milanković's theory eventually gained recognition and strong support from Köppen and Wegener, and later received further affirmation through contributions from Sergel, Ebrel, Berger, and Head III. In addition to his revolutionary work on Earth's climate history, Milanković also made significant contributions to the understanding of the migration of the magnetic poles over Earth's surface trough geologic history and the calendars.
Regional disparities in productivity: Evidence from NUTS 3 level in Serbia
Authors: Manić Emilija , Molnar Dejan , Mitrović Đorđe
Published: September 2024

One of the biggest challenges in Serbia today is uneven regional development. Serbian regional disparities are among the largest in Europe, characterized by distinct stratification and multidimensionality. The existing spatial inequalities are not only those of the traditional type "North - South" and Belgrade/Novi Sad in relation to the rest of the country, but there are also large increasing differences within the region (NUTS 2 level). However, despite all these development challenges, the issue of regional disparities in productivity has been hardly investigated by the scientific and professional public in Serbia. This paper intended to analyse the level of Serbian regional inequalities in productivity within the NUTS 3 areas (subregions). The goals of the research are: the investigation of the effectively usage of the production factors potential at the subregion level (primarily labor force), the determination of inequality degree in labor productivity, and ranking of the NUTS 3 areas according to that criteria. Hypotheses were tested using the data envelopment analysis method (DEA) and the efficiency coefficient, where the educational structure of the workforce, the share of investments in gross added value (investment rate), employment and the rate of opening new businesses were used as input indicators, while the output outcome was measured using ratio of gross value added (GVA) and the number of employees (approximation for labor productivity). The obtained results clearly indicate differences in the level of development potentials utilization within the observed territorial entities. These results can be used both for determining the basic directions of future development and regional policies, as well as an argument for considering territorial reorganization at the subregions level in Serbia.
Globalization and spatial distances: "End of geography" and "death of distance"?

Published: September 2024

Geographic distance between certain parts of the World during most of human history had the function of a barrier and reduced the possibilities of communication between them. The impossibility of quickly overcoming large distances and information exchange was the main obstacle to connecting distant societies and the main brake on the establishment of global connections. Advances in transportation technologies in the 20th century eased spatial barriers to some extent. But only with globalization, the emergence of the Internet and the development of information technologies at the end of the 20th century, the concept of geographic distance was radically changed and physical distance as a barrier was eliminated to a significant extent; terms like cyberspace, virtual reality, deterritorialization, etc. were created. Today, when social networks enable instant communication on a planetary level, in people's minds the compression of time and space leads to a completely different understanding of distance and its relativization. The increasingly easy transport of people and goods over long distances, the explosive growth of information and communication technologies and other phenomena contained in the term globalization have led many authors to discuss the diminishing importance of geographic distances as significant forces in driving economic and social activities. The concept of the "death of distance" and the "end of geography" were developed, which imply that in the modern world geographic distance is no longer important, because interpersonal communication and economic activities are increasingly transferred from real physical to virtual digital space. This paper critically examines these concepts, with the aim of proving how, even in conditions of total global networking, geographic distances still play a significant role in interpersonal relations and global economy.
The influence of changed bioclimatic conditions on urban planning: Analysis of the heat load in Belgrade during 30 years
Authors: Lukić Milica , Filipović Dejan
Published: September 2024

Under the influence of climate change, the urban microclimate is also changing. Air temperature is certainly one of the most important parameters used to describe the urban climate. However, since the urban microclimate is a very complex system, the impact of changed climatic conditions on the quality of life in urban areas cannot be monitored using only one meteorological parameter. In today's context, when we feel the effects of climate change on our well-being almost every day, planners and urban planners, as well as everyone else who participates in the creation of public policies of urban development, must change the way they perceive the urban microclimate. Analysis of outdoor thermal comfort should become an integral part of plans and strategies that determine the vision of the future development of our cities. In accordance with the above, this paper focuses on the analysis of the thermal comfort of the central zone of Belgrade, using the bioclimatic index Heat Load (HL) during a period of 30 years (1991-2020). The main goal of the research is to present how the thermal comfort in the central, most densely populated, and built-up parts of Belgrade has changed over the past three decades and how these findings can contribute to more sustainable urban development. The results are presented at the annual and seasonal level. The research is based on the daily meteorological data of RHSS, their mean daily and term values (07h, 14h, and 21h CET) recorded at the meteorological station Belgrade - Observatory (44°48N, 20°28E). The conducted analysis shows a moderate increase in the number of days with a higher degree of heat load, that is, days when the values of the HL index ranged from 1.026 to 1.180 (warm) and 1.181 to 1.750 (hot), especially during the summer months.

Published: September 2024

High-quality recreation contributes significantly to life satisfaction. In recent decades, this field has experienced intense changes. Recreational activities and their popularity are changing, even if the core of the most common activities (walking, hiking, cycling, swimming...) remains fairly stable. Many of the most widespread recreational activities are linked to specific recreational infrastructure, so the existence of an adequate and accessible recreational infrastructure is also important in terms of quality of life. In addition, recreational activities, especially outdoor recreation activities, also play a significant role in the context of tourism. In tourism areas, tourists are an important segment of recreational infrastructure users, and an attractive recreational infrastructure is often one of the factors influencing the choice of a particular destination. Accordingly, Slovenian tourism policy also pays a lot of attention to the tourism potential of outdoor recreation. Nevertheless, knowledge about the state of recreational infrastructure in Slovenia is very patchy, and data on recreational infrastructure is usually not systematically collected or does not exist at all. In order to enable the analysis of this important content area, we have created a typology of recreational infrastructure and compiled its inventory through extensive data collection. Various categories of recreational infrastructure are presented in the form of specific spatial layers with different attributes. Our research focused on the question of what are the main characteristics of recreational infrastructure in Slovenia, what is its spatial distribution and what are its specific characteristics in tourist areas. The characteristics of recreational infrastructure are influenced by demand, the specific environmental/geographical requirements of individual recreational activities as well as by various policies. The growing heterogeneity of recreational infrastructure and the emergence of new types of infrastructure are evident.
Sustainable rural economy of the Zlatibor region
Authors: Jeftić Marija , Nikolić Teodora
Published: September 2024

The paper presents the possibilities of reviving villages and the rural economy in Serbia in accordance with the concept of sustainable development. A stable ecological, economic and social environment is an important condition for the development of rural areas because it enables the establishment of a base that can prospectively enable employment from a local point of view and investments aimed at environmental protection. In modern times, the natural and living environment of rural areas are significantly threatened by the process of urbanization and its accompanying effects, which has been particularly reflected in the changes in the functional and socio-economic status of villages. The classification of urban and rural settlements, based on relevant indicators, creates a solid information base for all actors in the planning process, especially planners and decision-makers in the future conceptions of the development of various territories, i.e. strategies and planning documents, from local communities to entire national territories. Attention is devoted to the application of the mechanism of small development nuclei as a potential base for the population to remain in the countryside, production of healthy food, energy from alternative sources, environmentally acceptable waste treatment technologies, etc.
Spatial planning and political power
Authors: Đorđević Dejan , Pjanović Bojana , Tomić Tijana
Published: September 2024

This essay is dedicated to the old topic of the influence of politics on spatial planning. Planning is and has always been a state policy instrument in space and as such it is inevitably linked to the ideologies, interests and priorities of political structures. Under the circumstances of rapidly changing political parameters, both in Serbia and in the world, it is becoming increasingly difficult for planning to keep pace, especially when it comes to the long-term and relative stability of politics in space, which is a requirement for good planning in general. This is certainly not helped by the statements that the market is more important than the plan and that in the neoliberal concept spatial planning must not become a so-called business barrier. As a result of the explicit interest of political power in spatial development in Serbia in the first two decades of the 21st century, there has been an excessive politicisation of planning. It is enough to mention the recent examples of spatial plans for special purpose areas for the Belgrade Waterfront, Rio Tinto and the Spatial Plan of the Republic of Serbia, regardless of the quality of the planning solutions. In public discourse, planning is often labelled as risky, impossible, impotent, malicious and even unconstitutional. On the other hand, there is an opinion that spatial planning is alive and well and that it takes place according to the circumstances. The hypothesis that is further developed in the essay is that in order to remain effective in a changing political environment, spatial planning must become more pragmatic and, what is not new, must sometimes save space from political visions with the quality of planning solutions.
Integrated territorial investments a new opportunity for the development of urban areas

Published: September 2024

Cohesion policy, as one of the most important public and powerful investment policies of the European Union, aims to promote employment, i.e. overall economic development, and ultimately to improve the quality of life of citizens, both in the Member States and in the EU as a whole. In response to current challenges, the consolidation of the framework has led to numerous reforms, including the strengthening of the part focused on cities as agents of social and economic development. In this context, the Integrated Territorial Investment (ITI) mechanism emerged, which represents a new opportunity for the development of urban areas by integrating resources from various European funds and operational programs and investing in activities that strengthen the role of cities as drivers of overall development. The paper analyzes the possibilities of using the mechanism of integrated territorial investments, which was tested in Serbia in 2023 as part of the technical assistance of the European Union Local Development Program EU PRO Plus. Since one of the prerequisites for its application is the definition of urban areas and the adoption of their development strategies, the program supported local governments in applying an integral and sustainable approach to development planning, i.e. in the creation of territorial strategies. With the aim of improving the competencies of local self-government units in the introduction and implementation of an integral approach to territorial development, a total of 12 territories - urban areas comprising 31 local self-governments - were selected. Since the centers of urban areas become partners in the implementation of the ITI mechanism and are part of the system that manages the European Union funds, it is undeniable how important it is to enable local self-governments in Serbia to apply and optimally use the funds available in this financial framework. In this context, the paper aims to contribute to shedding light on the possibilities of using the ITI mechanism to support urban development in Serbia.

Authors: Gvozden-Sliško Dijana , Ćurić Ana , Ivanišević Marko
Published: September 2024

In the recent years, geoheritage and geodiversity have gained increased importance when it comes to nature protection. Term geoheritage defines sites both cultural important and natural heritage with emphasized geomorphological, geological, pedological, archeological (Article 15 "Official Gazette of Republic of Srpska" no.38/22), paleoarcheological and hydrological values. Therefore, geoheritage objects represent a significant geodiversity of the Republic of Srpska. Some objects of geoheritage, located within the territory of the Republic of Srpska, have been protected since the very beginning of institutional nature protection. Regarding its' importance, many geomorphological objects were protected as natural heritage by State institution for protection of cultural monuments and natural rarities in 1950s and 1960s. Some of the cave geoheritage objects that were under protection in the middle of 20th century are: Ljelješnica, Jurkovica, Rakovac, Čukovac, Provalija, Govještica, Banja Stijena, Vaganska and others. In the 21st century the trend of protecting natural heritage and geoheritage objects continues. The Republic Institute for the protection of cultural, historical and natural heritage made so far 15 Studies for the protection of cave geoheritage objects, among which 14 represents "Natural monuments" and one "Nature park". Important geoheritage that enjoys legal protection in accordance to the Law on Nature Protection are: Rastuša Cave, Ljubačevo Cave (northern RS), Ledana Cave, Vaganska Cave, Mračaj Cave (central RS), Mokranjska Miljacka Cave, Kuk Cave, Orlovača Cave, Ledenjača Cave, Girska Cave, Govještica Cave, Banja Stijena Cave (East RS), "Pod Lipom" Cave, "Velika pećina" Cave, Pavlova Cave and Đatlo Cave (South RS). In addition to the mentioned caves and pits, the Institute has also protected the canyon of the Prača River, where the caves Govjestica and Banja Stijena are located. The natural monument "Vrela Sane" was protected in 2021, thereby protecting the cave Mračaj. The geonatural heritage of the Republic of Srpska, with its geomorphological, geological, pedological, archaeological, and hydrological significance, represents potential for the development of geotourism, which is why special attention needs to be directed towards proper and functional management of protected geoheritage. The geoheritage of the Republic of Srpska, its preservation, and protection represent a significant part of the modern concept of nature conservation, which includes the protection and use of natural resources within the framework of sustainable development.
New trends in the development of regional geography at the Faculty of Geography in Belgrade
Authors: Pavlović Mila
Published: September 2024

Regional geography is one of the oldest geographical disciplines. It was included in the school curriculum after the First World War. Regional geography at the Faculty of Geography has gone through many phases, ups and downs. In the 20th century, its development followed by the contemporary trends of regional geography in the world, applied to the territory of the former Yugoslavia and Serbia. In the two and a half decades of the 21st century, there have been new trends in the development of regional geography. However, the question arises as to whether such regional geography at the Faculty of Geography is based on the principles of modern scientific directions. Can articles that only formally have the term regional in their title be categorised as regional geography? A certain number of dissertations have insufficiently clear content that belongs to other fields, e.g. tourism, environment, etc., rather than to regional geography. In the last two and a half decades, some supervisors and committee members of dissertations in regional geography often have no experience in studying the fields the dissertation deals with, while members with sufficient experience are avoided. This raises the question of their competence in regional geography. International journals publish articles by regional geographers who have absolutely no scientific connection to regional geography topics. One of the problems of contemporary regional geography at the Faculty of Geography in Belgrade is the diminishing scope of field work, as the problems, processes and trends of a given area are increasingly viewed only from a cabinet perspective. The question rightly arises whether the new tendencies in the development of regional geography at the Faculty of Geography follow modern trends or whether the classical, traditional regional geographers should keep their distance from the new tendencies?

Iraq’s Lost Century

Published: September 2024

Shia religious authorities, in collaboration with their political allies in the Iraqi parliament, seek to redefine Iraq’s personal status law according to religious rules. On July 29, the largest bloc in Iraq’s parliament, introduced a controversial bill to amend the Personal Status Law of 1959. This proposed amendment would mandate that Iraqis, upon marriage, choose either Shia or Sunni jurisprudence to govern all personal status-related matters within their marriage. This change creates legal uncertainty by replacing predictable, codified law with premodern, uncodified Islamic jurisprudence. Moreover, it disproportionately affects women, especially by facilitating early marriages.
Digestion products of bread and cheese cause addictive behavior in a planaria model
Authors: Cochin Dylan , Barcus Gillian , Edelberg Martin
Published: September 2024

Addiction is defined as compulsive engagement in certain practices despite considerable danger and other harmful consequences. Gluteomorphin and casomorphin are peptides derived from the digestion of bread and cheese and are known to bind to opioid receptors. However, it is unclear if gluteomorphin or casomorphin are addictive in a similar manner to extrinsic opioids such as morphine. Since 75% of the American diet consists of wheat and dairy, the implication of addiction could have a major impact on diet and obesity. Thus, the purpose of this study was to investigate the addictive potential of gluteomorphin and casomorphin in a planaria model. We conducted controlled experiments comparing planaria exposed to water, gluteomorphin, or casomorphin. We utilized light/dark testing, motility, & stereotypical movements to test for acute exposure, withdrawal, sensitivity/tolerance, environmentally placed conditioning, and cross sensitivity with nicotine. Our results from acute exposure, abstinence induced withdrawal, environmentally placed conditioning, and sensitization/tolerance assays suggest that gluteomorphin and casomorphin are addictive. Additionally, results in cross sensitization testing with nicotine were inconclusive and further evaluation is recommended. These findings establish grounds to further investigate the potential addictiveness of gluteomorphin and casomorphin, digestion products of bread and cheese respectively.

Aiming at Gaussian white noise in remote sensing images, a remote sensing image denoising algorithm based on shearlet transform and goodness of fit test is proposed. Firstly, the noisy remote sensing image is decomposed into different sub-bands by shearlet transform, and the denoising threshold is estimated by using the statistical relationship of Gaussian white noise coefficients in shearlet domain; secondly, the goodness of fit test statistic of high-frequency sub-band is calculated, and the statistic is compared with the denoising threshold for denoising; finally, the coefficient matrix is inversely shearlet transformed to reconstruct the denoised image. Simulation experimental results show that the algorithm can effectively remove Gaussian noise in remote sensing images, maintain the edge texture information of the image, and obtain a higher peak signal-to-noise ratio under different noise levels, which is an average improvement of 0.33 dB compared with the shearlet threshold denoising algorithm.

Published: September 2024

Aiming at the problem that the detection of abnormal data in multidimensional data sets is not processed by dimensionality reduction, which leads to low detection accuracy, high false positive rate and long detection time, a method for detecting abnormal data in multidimensional data sets based on spectral clustering is proposed. Firstly, the data in the multidimensional data set is clustered by Laplacian matrix to preliminarily classify the data; secondly, the local linear embedding (LLE) algorithm is used to reduce the dimensionality of the classified data, and the high-dimensional data set is expressed by feature vectors to remove redundant information in the multidimensional data set; finally, the processed multidimensional data set is input into the support vector machine model, and the abnormal data is detected according to the calculation of regression estimation value. Experimental results show that the proposed algorithm has higher accuracy, lower false positive rate and shorter detection time for detecting abnormal data in multidimensional data sets.

Authors: Delin Li , Junxian Chen , Yonggang Wang , Lu Wang , Zhaoqing Shen
Published: September 2024

Aiming at the problem of distinguishing the driving characteristics of different types of drivers in sharp bends, a driver behavior classification method based on vehicle driving parameters was proposed. By analyzing the real vehicle driving data, six variables were selected, namely, vehicle type, speed before entering the bend, speed after exiting the bend, deceleration behavior before entering the bend, whether to follow the car, and speed difference between entering and exiting the bend. A latent class model was constructed, and the characteristics of different types of drivers were determined based on the model. The results show that the model can classify drivers in sharp bends into three types: stable type, restricted type, and free type. The characteristic parameters of stable type drivers are in the median of the three types of drivers, and they tend to enter and exit the bend at a constant speed; restricted type drivers have the most obvious deceleration or following driving characteristics when entering the bend; and free type drivers have the highest speeds entering and exiting the bend, and the deceleration behavior after exiting the bend is the most obvious.

Authors: Yisun Chen , Zhang Xiaoman , Cai Ning , Mou Shuangli , Yu Zong
Published: September 2024

The digital intelligence-driven marketing technology and online sales service functions of network platforms are conducive to the production and sales of green products. Therefore, this paper constructs a network platform supply chain model consisting of a manufacturer and a platform, considering that the manufacturer invests in green technology to produce products, and the network platform uses consumers' online shopping data to carry out digital intelligence-driven marketing activities. The marketing strategy of the manufacturer and the platform co-marketing green products is studied, and the problem of the manufacturer using the cost-sharing contract to cooperate with the network platform to carry out digital intelligence-driven marketing of green products is considered. The study found that: 1) Optimizing green investment and digital-driven marketing costs, as well as enhancing consumers' sensitivity to green products and digital-driven marketing, are conducive to improving the profitability of network platform supply chain members and the green level of products; 2) Under the agency sales strategy, the commission rate charged by the network platform is the main factor affecting the sales strategy choices of manufacturers and platforms. There is a commission rate threshold that allows manufacturers and platforms to obtain more profits compared to the resale strategy; 3) Under the agency sales and resale strategies, manufacturers can use cost-sharing contracts to effectively incentivize network platforms to sell green products, and there is a cost-sharing threshold that allows manufacturers and network platforms to have the opportunity to obtain Pareto-improved profits. Network platforms charging less commissions and manufacturers sharing larger marketing costs are conducive to achieving a win-win situation in economic and ecological benefits.

Introduction: Tooth autotransplantation is the replacement of aɸmissing tooth with another tooth within aɸpatient’sɸdentition. It usually involves aɸtransfer of an impacted or erupted tooth from aɸdonor site to an extraction or surgically created recipient site. Material and method: The patient (12 years) with two impacted maxillary canines (13 and 23) was referred to the Orthodontic department of Clinic of Stomatology and General University Hospital. The patient underwent orthodontic treatment combined with autotransplantation of teeth 13 and 23. The case report presents the autotransplantation of impacted canines with incomplete root formation and preserved vitality after the procedure. Conclusion: Full esthetics as well as function of the dentition with lower financial demands was achieved by the autotransplatation of both impacted canines. It is another treatment option, especially in case of impacted teeth in unfavourable position which does not allow active orthodontic extrusion or where standard treament could be associated with an increased risk of damage to the adjacent anatomical structures.
A magyarországi jogharmonizáció elmúlt húsz éve – mennyiségi, minőségi gyorselemzés

A magyarországi jogharmonizáció jóval hosszabb időre nyúlik vissza, mint a tagság elnyerése óta eltelt húsz esztendő. Ez természetes, hiszen a csatlakozásnak komoly jogi feltételei voltak: hazai jogunkat képessé kellett tenni az uniós normák befogadására, sőt, ezen joganyag nagy részét már a csatlakozást megelőzően át kellett venni. Az, hogy mindez milyen megközelítéssel és milyen módszertannal történik, meghatározó nemcsak a tagállami jog megfelelő reakcióképessége szempontjából, hanem a nemzeti jog integritásának megőrzése okán is. Az alábbi írás azt veszi végig, hogy a magyar jog hogyan viszonyult az egyes uniós jogforrásokhoz, milyen harmonizációs kitettségekkel nézett szembe és ezekre milyen megoldásokat adott.
Az Európai Unió és a tagállamok viszonyának történelmi alakulása és jövője

Magyarország 20 éve tagja az Európai Uniónak és ez kihatással van közjogi intézményeire. Magyarország és más országok alkotmányai feljogosítják a tagállamokat az Unióban való részvételre, ugyanakkor meghatározzák a szupranacionális szintű együttműködés határait is. Az alkotmányos uniós klauzulák tekintetében az uniós együttműködés bővülésével folyamatos tartalmi növekedés mutatható ki. Az európai uniós intézmények és a tagállamok közötti párbeszédben vita alakulhat ki az uniós és a nemzeti jog közötti hierarchikus viszonyt illetően, amely elsősorban az Európai Bíróság és a tagállamok alkotmánybíróságai között manifesztálódik. Az uniós tagság kihatással van a hatalommegosztásra, a demokrácia és jogállamiság kontrolljára.

Bu araştırma Erzincan ilinde bulunan bir eğitim ve araştırma hastanesinde görev yapan sağlık çalışanlarının tekno-stres algıları ile mesleki tükenmişlikleri arasındaki dolaylı ilişkide dönüşümcü liderlik davranışlarının aracılık rolünü tespit etmek amacıyla gerçekleştirildi. Araştırma amacı doğrultusunda literatürdeki tekno-stres (bağımsız değişken), mesleki tükenmişlik (bağımlı değişken) ve dönüşümcü liderlik (aracı değişken) ölçekleri kullanıldı. Hastanede doktor, hemşire, diğer sağlık personeli, idari personel ve destek personeli olarak görev yapan 1462 çalışandan basit rastgele örnekleme yöntemi kullanılarak 341 kişiye ulaşılarak araştırma gerçekleştirildi. Araştırma amacı doğrultusunda belirlenen hipotezlerin sınanabilmesi için AMOS22, SPSS 27 ve process macro eklentisi kullanılarak geçerlilik ve güvenirlik analizleri, korelasyon analizi ve aracılık rolünün tespiti için de process macro model 4 uygulandı. Araştırma sonuçlarına göre sağlık çalışanlarının tekno-stres düzeyleri ile mesleki tükenmişlikleri arasında istatistiksel olarak anlamlı ve yüksek düzeyde pozitif bir ilişki tespit edildi. Ayrıca sağlık çalışanlarının tekno-stres düzeyleri ve mesleki tükenmişlikleri ile dönüşümcü liderlik davranışları arasında istatistiksel olarak anlamlı ve yüksek düzeyde negatif bir ilişki bulgulandı. Sağlık çalışanlarının tekno-stres algıları ile mesleki tükenmişlikleri arasındaki dolaylı ilişkide dönüşümcü liderlik davranışlarının kısmi aracılık rolüne sahip olduğu da belirlendi. Sonuç olarak yapılan araştırma ve bulgular değerlendirildiğinde ayrıca ilgili alan yazını incelendiğinde özellikle yerli literatürde tekno-stres ile mesleki tükenmişlik arasındaki ilişkide dönüşümcü liderliğin aracı rolünün irdelendiği bir çalışmaya rastlanmamıştır. Yapılan bu çalışmanın ilgili literatüre önemli bir değer sağlayacağı düşünülmektedir.
