Transforming leaders to transform hospitals. Cultivating ethical leadership for compassionate healthcare
Authors: Ricci Elena
Published: October 2024

The importance of compassionate care has been widely acknowledged in the literature as a crucial component for enhancing patient care, improving clinical outcomes, and reducing burnout, compassion fatigue, malpractice, and healthcare costs (Watts et al., 2023). However, many healthcare systems continue to struggle with effectively implementing and sustaining compassionate care practices due to the burden of administration, limitations in resources, and a focus on efficiency and profitability. The purpose of this paper is to advocate for the necessity of (re) “humanizing” the healthcare environment, which is urgently needed today to counteract the trend of eroding the value or essence of care practices by refocusing on the patient and their family. Specifically, this paper will argue that to reverse this trend, it is crucial to transform the education of healthcare facility leaders and managers at all levels. It is vital to provide them with guidelines and training that is not only technical but also ethical, with a focus on character education. This approach would enable them to recognize the right values and effectively address complex situations from a moral perspective. Providing leaders with the opportunity to flourish through dedicated programs can positively transform our hospitals and healthcare facilities. Such programs are essential for creating a balanced healthcare environment where efficiency and compassionate care coexist, leading to improved care outcomes, reduced costs, and enhanced well-being for professionals.

Authors: Chetty Sheldon , Ross Andrew
Published: October 2024

Background: South Africa has high number of patients on antiretroviral treatment, necessitating innovative approaches to decongest healthcare facilities. The Central Chronic Medicines Dispensing and Distribution (CCMDD) programme is a national initiative that identifies stable chronic patients for collection at pick-up points away from the health facility. This study aimed to compare patient satisfaction and virological suppression among those who collected medication through the CCMDD programme and routine care.Methods: This descriptive retrospective analytical study was conducted at a community health centre in Pietermaritzburg from 01 January 2018 to 31 December 2018 and included a questionnaire and access to their medical records on the national medicines database. The 117 patients in the routine care and CCMDD programme groups were assessed at baseline and evaluated at 6 months and 12 months, which were the time points for viral load (VL) testing.Results: Of the 234 participants, 34 out of 117 (31.6%) remained in routine care at the 6-month review, and all but 7 patients had transferred to the CCMDD after 12 months. At the end of the study, 7 patients had VLs above 50 copies/mL and continued in routine care, while 97% (n = 27/234) remained virologically suppressed. None of the CCMDD programme patients moved out of the programme.Conclusion: Satisfaction with the CCMDD programme is indicated by the patients’ continued VL suppression, highlighting its potential to decongest healthcare facilities and reduce the strain associated with medication collection.Contribution: The findings in this study validate patients being registered onto the CCMDD programme.

Authors: Saleem Renas N. , Yassin Ahmed Khudair
Published: October 2024

BACKGROUND:

Gene expression profiling has become a fundamental tool in cancer diagnosis and management. B-cell non-Hodgkin lymphoma (B-NHL) is a group of malignant neoplasms originating from the lymphoid tissues, mainly the lymph nodes and the gene expression technique was used to unravel its complexity and aid in clinical decision-making.

OBJECTIVES:

The aims of this study were to find the significance of gene expression profiling focusing on colony-stimulating factor 1 receptor (CSF1R), myeloid differentiation factor 88 (MyD88), and tumor necrosis factor-α (TNF-α) as a promising approach in B-NHL diagnosis and their comparison with healthy controls.

PATIENTS, MATERIALS AND METHODS:

The current clinical prospective study was mediated from June 1, 2021, to December 30, 2022, of NHL patients in Kurdistan, Iraq. Seventy-three patients were recruited from Nanakali Hospital for Blood Diseases and Cancer, Erbil. The integration of gene expression biomarkers uses quantitative real-time polymerase chain reaction technique to diagnose B-NHL. Specifically, we focused on three key genes MyD88, TNF, and CSF1R whose expression profiles were analyzed in B-NHL patients and controls. We leveraged a dataset to explore gene expression patterns in B-NHL and applied classification algorithms to distinguish between B-NHL patients and controls.

RESULTS:

The initial results show the overall lower CSF1R expression in B-NHL as compared to the controls and a significant reduction in CSF1R expression in females (≤50 years and >50 years). The result considers lower CSF1R expression in B-NHL males (≤50 years) and higher but not significant in males (>50 years).

CONCLUSIONS:

These B-NHL-expressed genes may be considered potential diagnostic markers with their meaningful comparisons to control groups, and they could be proposed to guide the management of patients and facilitate their stratification into clinical trials.
Expanding the therapeutic horizon in acute myeloid leukemia: The role of phosphoinositide-3-kinase-γ inhibition
Authors: Das Soumyajit , Singh Mahendra Pratap , Rai Nishant , Sah Sanjit
Published: October 2024

Acute myeloid leukemia (AML) remains a formidable challenge due to its high relapse rate and limited therapeutic options. This study investigates the role of phosphoinositide-3-kinase-γ (PI3Kγ) in AML and explores the therapeutic potential of the PI3Kγ inhibitor, eganelisib, in preclinical models. Using genome-wide CRISPR interference screening, we identified PI3Kγ as a critical survival pathway in certain AML subsets. We demonstrated that inhibition of PI3Kγ with eganelisib disrupts oxidative phosphorylation, thereby impeding AML cell survival and proliferation. Notably, the combination of eganelisib with cytarabine showed enhanced efficacy, suggesting a synergistic interaction that improves treatment outcomes. These findings indicate that PI3Kγ is a viable therapeutic target in AML and that PI3Kγ inhibitors could be pivotal in overcoming treatment resistance and reducing relapse.

Authors: Cao Jiaru , Zhang Ling , Tang Baopeng
Published: October 2024

Arrhythmias are a common cardiovascular disease with multiple clinical manifestations, of which ventricular arrhythmias may indicate the risk of sudden cardiac death. Although great progress has been made in the treatment of ventricular arrhythmias, there is still no solution for sudden malignant arrhythmic events. Portable electrocardiogram (ECG) monitoring tools play a vital role in the process of monitoring spontaneous arrhythmias, especially in early cardiovascular diseases without clinical symptoms, the use of ECG monitoring tools can provide more timely and accurate observation of the occurrence of occult arrhythmias. This mini-review summarizes the application of ECG monitoring tools in the process of arrhythmias and provides a potential reference for monitoring the occurrence of early arrhythmias.

Authors: Mairuae Nootchanat , Buranrat Benjaporn , Yannasithinon Supataechasit , Cheepsunthorn Poonlarp
Published: October 2024

Purpose: To investigate the antioxidant and anti-inflammatory effects of Oroxylum indicum (L.) Kurz leaf extract on lipopolysaccharide (LPS)-activated BV2 microglia.
Methods: BV2 cells were treated with LPS for 24 h in the presence or absence of Oroxylum indicum (O. indicum) leaf extract. The levels of reactive oxygen species (ROS), nitric oxide (NO), and interleukin 6 (IL-6) were quantified with CM-H2DCFDA, Griess reagent assay, and  enzyme-linked immunosorbent assay (ELISA) test, respectively. The antioxidant activity of O. indicum leaf extract was assessed in vitro using DPPH, ABTS and FRAP assays.
Results: Treatment with LPS resulted in significant increases in the levels of ROS, NO, and IL-6, when compared to untreated cells.  However, co-treatment with O. indicum leaf extract significantly suppressed the production of these inflammatory markers (p < 0.05). In  addition, the leaf extract of O. indicum exhibited antioxidant activity in the DPPH, ABTS, and FRAP assays. The contents of flavonoids and  phenolics in O. indicum leaf extract were 13.25 ± 0.163 mg QE/g of dried extract and 82.58 ± 1.772 mg QE/g of dried extract, respectively (p  < 0.05).
Conclusion: The leaf extract of O. indicum exhibits anti-inflammatory and antioxidant properties in LPS-activated BV2 cells.  This finding indicates that the leaf extract of O. indicum has promising potentials as a new source of herbal medication with anti- inflammatory properties. However, there is a need for more studies to unravel the fundamental mechanisms of their actions.
Effect of intravenous thrombolysis with butylphthalide, edaravone and recombinant tissue plasminogen activator (rt-PA) on serum inflammatory factors in patients with ischemic stroke
Authors: Zhe Xiao , Zhang Shijun , Ren Huiyun
Published: October 2024

Purpose: To study the impact of edaravone in combination with edaravone and recombinant tissue plasminogen activator (rt-PA)  intravenous thrombolysis on serum inflammatory factors in ischemic stroke subjects.
Methods: Eighty ischemic stroke patients in the First Affiliated Hospital of Xi'an Medical University, Xi’an, China were randomly assigned  to study and control cohorts, each with 40 subjects. Patients in control cohort were administered edaravone and rt-PA intravenous  thrombolysis. The study cohort received butylphthalide in combination with edaravone and rt-PA intravenous thrombolysis. Treatment effectiveness/efficacy, neurological function, self-care ability, inflammatory indicator levels, and blood cell levels were compared between  the 2 cohorts.
Results: Efficacy was significantly better in the study cohort than in the control cohort (p < 0.05). After treatment, NIHSS  score was significantly lower in the study cohort than in control cohort, while ADL score was significantly higher in the study cohort (p <  0.05). After medication, CRP level was decreased significantly in both cohorts, but was significantly lower level in the study cohort (p <  0.05). Treatment led to significant reductions in white blood cell count, neutrophil count, and NLR ratio in the study cohort, relative to the  control cohort (p < 0.05).
Conclusion: The use of butylphthalide in combination with edaravone and rt-PA intravenous thrombolysis  produces significant and beneficial effects on ischemic stroke subjects by regulating abnormal levels of inflammatory cells, improving  coagulation status and decreasing inflammation. Moreover, it ameliorates neurological defects and improves activities of daily living.  There is, however, a need to determine the mechanisms of action of this combination therapy and the influence of other cofounding  factors on the activities of the combination therapy.

Published: October 2024

Purpose: To investigate the effect of adipose-derived mesenchymal stem cells (ADMSCs) on doxorubicin (DOX)-induced cardiomyopathy in rats.
Methods: A total of 30 male Sprague-Dawley rats were randomized into control (n = 10) and study groups (n = 20). Control group  received no intervention while the study group received DOX administered intraperitoneally (i.p.) six times daily at a dose of 2.5 mg/kg/ day. The study group was divided into 2 groups. One group received DOX + normal saline (0.9 %w/v) sodium chloride (NaCl) solution  ntraperitoneally at a dose of 1 mL/kg/day. Another group received DOX + ADMSC at a dose of 2.0 x 106 cells/kg intraperitoneally twice a  week. Biochemical parameters and histopathological changes in blood and heart tissue samples were compared among groups.
Results:  Caspase-3 immuno-expression, plasma malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), growth differentiation  factor-15 (GDF-15), pro-brain natriuretic peptide (Pro-BNP), troponin, heart transforming growth factor–β (TGF-β) were significantly lower  in DOX+ ADMSC compared to DOX + saline group (p < 0.05). However, caspase-3 immune expression and the number of regularly arranged cardiomyocytes significantly decreased in DOX + ADMSC group compared to DOX + saline group (p < 0.05).
Conclusion:  Adipose-derived mesenchymal stem cells (ADMSCs) reduce caspase-3 immunoexpression, restore cardiac histology, and ameliorate DOX- induced cardiac injury. Further investigation and clinical trials are recommended, especially to determine the continued safety and efficacy of AD-MSC-based therapy in cardiac injury.
In-Plane and Out-of-Plane Bending Vibration Analysis of the Laminated Composite Beams Using Higher-Order Theories
Authors: Prof. R-Ali Jafari-Talookolaei
Published: October 2024

In this paper, higher-order shear deformation theories for a thorough analysis of the in-plane and out-of-plane vibrational characteristics of laminated composite beams have been presented. Through the introduction of new displacement fields and the consideration of rotary inertia and Poisson's effect, the kinetic and potential energies of the beams have been derived. This formulation, displaying significant generality, accommodates arbitrary stacking sequences. Utilizing the finite element method, a new element has been presented for calculating the beam's vibrational characteristics. Featuring three nodes, each with seven degrees of freedom, this higher-order element provides a detailed representation of complex behaviors. Mass and stiffness matrices have been derived using the energy method and apply boundary conditions through the penalty approach. The results exhibit a high degree of consistency and alignment with those obtained from the 3D commercial software ANSYS, validating the accuracy and reliability of the proposed methodology for structural analysis. This comprehensive approach contributes to advancing the understanding and modeling of laminated composite beams in diverse engineering applications. The effects of different parameters on the in-plane and out-of-plane vibration analysis of laminated composite beams have been investigated in detail.

Bovine neonatal diarrhoea (BND) is a problem of great relevance in cattle herds, resulting in a decline in productivity and performance in production units, and causing great economic losses. The objective of the study was to determine the prevalence of BND in the state of Veracruz. In total, 300 lactating calves were sampled. Samples were analysed for Rotavirus, Coronavirus, Escherichia coli and Cryptosporidium spp. Differences between groups were determined by chi-square and risk factors were determined by Odds Ratio. The general prevalence of three geographical areas sampled was 85%. Regarding the analysed pathogens, Cryptosporidium spp. Had the highest prevalence with 76%, followed by E. coli with a prevalence of 42%. Two pathogens were present in coinfections with a 32% prevalence, unlike diarrhoea caused by one, three or four pathogens. Calves that consume standing water after birth present a higher risk of infection. It is necessary to establish sanitaryprogrammes to reduce the risk of infection, help to avoid economic losses, and improve the productivity of the herd. BND related pathogens Rotavirus, Coronavirus, Escherichia coli and Cryptosporidium spp. are present in the sampled areas.

Published: October 2024

Salmonellosis is one of the most common food-borne zoonoses, and the most common source of infection for humans is meat and meat products. In 2023, 1125 samples of portioned meat (chicken, pork, beef) were tested in butcher shops in five districts of northern Croatia. The samples were tested for the presence of bacteria of the genus Salmonella, which were isolated in 88 (7.82%) samples. Salmonella was isolated from 604 chicken meat samples in 69 (11.4%) samples, from 319 pork samples in 10 (3.1%) samples and from 202 beef samples in 9 (4.5%) samples. Serological typing identified S. Infantis in 60 (87%) isolates from chicken meat samples, S. Mbandaka in 6 (8.7%) and S. Enteritidis in 3 (4.3%) samples. In pork, S. Derby was identified in 2 (20%) isolates, S. Typhimurium, S. Typhimurium (monophasic), S. London and S. Rissen in one isolate each (10%). In beef, S. Bovismorbificans was detected in 5 (55.6%) and S. Muenster in one (11.1%) isolate. Salmonellosis can be an economic problem due to the damage it causes in intensive production, but also a significant public health challenge as it spreads into the environment through the consumption and handling of contaminated meat in slaughterhouses, food processing and retail facilities. The implementation of appropriate hygiene measures and good hygiene practices from farms and slaughterhouses to butchers could help to reduce the contamination of meat with bacteria of the genus Salmonella.

Authors: Kameneff Marine , Marques Inês , Lima Tiago , Saavedra Maria José , Anastácio Sofia , Da Silva Gabriela Jorge , Silveira Eduarda
Published: October 2024

Carbapenemase-producing (CP) strains represent a substantial global threat, deactivating carbapenems and conferring resistance to β-lactam antibiotics. They can spread across various environments, yet data on their presence in marine animals are sparse. This study aimed to assess the occurrence of carbapenemase-producing strains in wild marine animals and to analyse their antimicrobial resistance (AMR) profiles to crucial antimicrobials and heavy metals frequently encountered in the marine environment due to anthropogenicactivity. A total of 28 samples were obtained from a fish auction in the Centre Region of Portugal. Non-fermenting bacilli (NFB) was isolated from the visceral content of wild marine animals. Identification of isolates was achieved through PCR-based amplification of the 16S rRNA gene, followed by sequencing. Antimicrobial susceptibility testing was conducted according to EUCAST guidelines, covering nine antimicrobials. Research of carbapenemases and metal tolerance genes was conducted by PCR, and statistical analysis utilized the Fisher’s exact test. Pseudomonas spp. and Aeromonas spp., among other isolates were identified (n=47/9/7, respectively). Susceptibility profiles showed 100% resistance or intermediate resistance to ticarcillin, piperacillin, piperacillin-tazobactam, ceftazidime, ciprofloxacin, and imipenem (n=63/63), while 27% were resistant to meropenem (n=17/63) and 13% to tobramycin (n=8/63). All of them exhibited susceptibility to amikacin and carried multidrug resistance (MDR) profiles, including heavy metal genes (merA and silA). None harboured the carbapenemase genes searched (blaKPC, blaGES, blaIMP, blaNDM or/and blaVIM). In this study, MDR profiles to clinically important antimicrobials were observed, including to carbapenems. However, no carbapenemase-producing strains were identified, suggesting the presence of other genes or alternative mechanisms of resistance. These findings underscore the importance of monitoring AMR in marine ecosystems, particularly given its close ties to the food chain.

BuddhistRoad Paper 2.9 "Chan Practice, Summer Retreat, and Winter Retreat of Uyghur Buddhists as Seen from Old Uyghur Practitioner Inscriptions"
Authors: Fu Ma
Published: October 2024

Like pilgrims, Uyghur Buddhist practitioners also left inscriptions at various Buddhist sites during the 10th to the 14th centuries; for the most part, these have been ignored or mistaken for pilgrim inscriptions. Since the practices and general life of Uyghur monks are still not clear, due to a lack of written records, the practitioner inscriptions, though fragmentary and rare, contain highly valuable data. These inscriptions provide evidence of the practice of Chan Buddhism (Chin. chanzong 禪宗) and the annual monastic retreat of the Uyghur Buddhists. In addition to a summer retreat, some Uyghur monks also participated in a winter retreat, just like the monks in Dunhuang (敦煌). However, many Uyghur monks did not last for the full three months required by Buddhist teaching.

Authors: Shoalihin Shoalihin , Suhaety Yeye , Lestari Atun
Published: October 2024

The use of Smartfren SIM cards is increasing along with the public's need for fast and stable internet services. However, a deep understanding of public interest in the SIM card is necessary to optimize marketing strategies and increase sales. Proper analysis can help companies identify potential target markets and develop effective marketing strategies. We chose the K-Nearest Neighbors method to analyze public interest in using Smartfren SIM cards. This study aims to develop and evaluate the K-Nearest Neighbors model in predicting public interest in using Smartfren SIM cards. This study uses a dataset containing information about Smartfren SIM card users. We divide the data into two sets: a training set for model building and a test set for evaluating model performance. We apply the K-Nearest Neighbors method to classify the data into two categories: interested and not interested. We evaluate the model performance using accuracy, precision, recall, and F1-score metrics. We present the evaluation results as a confusion matrix. The developed K-Nearest Neighbors model showed excellent performance with an accuracy of 94.29%, a precision of 94.20%, a recall of 100%, and an F1-score of 97.01%. These results indicate that the K-Nearest Neighbors model is effective in predicting people's interest in Smartfren SIM cards. The high recall value indicates that the model is able to identify all interested individuals without missing any, while the high precision value indicates that the model rarely makes false positive prediction errors. This study concludes that the K-Nearest Neighbors method is very effective for use in analyzing people's interest in using Smartfren SIM cards. We can rely on the developed model's strong performance for real-world applications in marketing strategies.

Hazardous natural processes and phenomena of various origins not only have a direct negative impact on the population and the economy, but also could act as a kind of “trigger” for the occurrence of accidents and emergencies in the technological systems and infrastructure facilities that they affect. Such types of accidents and emergencies, which are triggered by the impact of any natural hazard, are considered as natural hazard triggered technological accidents (so called Natechs). Especially dangerous social and environmental consequences have accidents resulting in releases of various pollutants. Accidents that disrupt the normal living conditions of the population create emergency situations. The paper presents the results of a long-term study of Natech events, their causes and consequences, temporal and regional distribution in the Russia. The observation period was 1991–2023. The main research method is the compilation of an electronic database (DB) of technological accidents, followed by statistical and geographical analysis. The information in the DB is collected in a structured form that allows searching and computer processing of the accumulated data. Data about previous dangerous events, collected in a DB over a sufficiently long period of time (more than 30 years in our case), can be interpolated to predict their future development, as well as to assess natural risks for the population. The author’s DB contains information about accidents and emergencies at technological facilities that occurred in Russia since 1991, including those caused by the impact of natural hazards. The main types of Natechs are distinguished. The areas of the highest risk of their occurrences have been identified. The contribution of various natural factors to the formation of the identified types of Natechs has been studied. Almost half of all events (48%) were caused by the impact on technological objects of a whole complex of dangerous hydrological and meteorological processes and phenomena, which include unfavorable combinations of various climatic parameters and hazards, such as strong winds, liquid and solid precipitation, floods, hard frosts, heat waves, lightning strikes, and others

The paper presents the results of a survey conducted among the population of two protected areas (PAs) in Serbia − the Carska Bara Special Nature Reserve (SNR) and the Vlasina Outstanding Natural Landscape (ONL). The aim was to determine whether the proclamation of a protected area affects the daily life and economy of the local population and how much the local community is involved in the management process? Emphasizing tourism as the only sustainable activity suitable for protected areas, a survey was conducted. The two areas analyzed here were chosen due to the proximity of settlements, i.e. their presence in the area of protected property, the still present traditional way of using natural resources (grazing, beekeeping, collecting mushrooms, snails and fruits, exploitation of mineral raw materials, fish farming) and the use of wild flora and fauna (mowing meadows, use of reeds and rushes), and length of tenure under protection. An additional point of interest is the fact that one of them is a plain and the other is a mountainous area. The perception of the local residents about life in the protected area, their future plans and the manager, were obtained. Respondents answered questions concerning their perception of everyday life in a protected area. Do they have personal benefit or harm? Are they engaged in tourism? Can they make a decent living from tourism? Is the number of visitors is higher after obtaining the protected status? Who is the manager and is he caring more about nature or the needs of the local population? The survey included 474 residents older than 18, in five settlements of the Carska Bara Special Nature Reserve and in seven settlements of the Vlasina Outstanding Natural Landscape. 39.0% women and 61.0% males made up the sample. The respondents’ average age was 40.8 years old. The majority of those surveyed belonged to the employee category. Responses were analyzed using descriptive demographic statistics, with the help of the Statistical Package for the Social Sciences. The obtained results are quite pessimistic, because they confirm the initial assumption that the population of protected areas in Serbia has very little or no benefit at all from living near a protected area.

As a historian of geography, I work on what constitutes geographical science, its object of study, its founding concepts and methodology; I analyze how geography is born and developed at the national and international levels through the circulation of knowledge. Therefore, I wondered about the apparent paradox contained in the very title of the congress (5th Congress of Slavic Geographers and Ethnographers) which closely associates geography and ethnography, in the continuity of previous congresses dating from the interwar period (Prague 1924, Poland 1927, Kingdom of Yugoslavia 1930 and Kingdom of Bulgaria 1936). In many countries, the academic world of the social sciences appears today increasingly compartmentalized; in geography in particular, there is on one side human geography and on the other physical geography, this was not the case during the interwar period, at the time of the first four congresses. What does this association with ethnography say about the evolution of geography (I speak here from the point of view of the geographer that I am) as a discipline at a time when geomorphology is predominant in geography? What are the links between ethnography, human geography and physical geography at the time of the first four congresses of Slavic geographers and ethnographers? In an attempt to shed light on this issue, I propose to study the part of human geography and ethnography in the 27 field notebooks of the French geographer Emmanuel de Martonne based on the results of a research program that I have coordinated at the Centre Nationale de la Recherche Scientifique (CNRS) and entitled Corpus Emmanuel de Martonne. Given the close links between Emmanuel de Martonne and Jovan Cvijić, two great geomorphologists (but not only) internationally recognized, I will introduce some comparisons between them. After discussing the emergence of concepts related to human geography in the first half of the 20th century, the presentation will show what methodology and field tools are used by E. de Martonne and J. Cvijić to describe and explain human facts.
GEOPHILOSOPHY OF MODERN: PROLOGOMENA
Authors:   University of East Sarajevo, Faculty of Philosophy, Department of Geography, Pale, Bosnia and Herzegovina, Mutabdžija Goran
Published: October 2024

This paper provides a methodological framework for the synthesis of geographical thinking during the century-long period of modern, which began with the introduction of regular university geography classes in the 1870s and ended with the announcement of the spatial turn in the social sciences in the 1970s. To offer an original solution in the field of research on contemporary geographical thinking, the author started from the analysis of reference works in this field. Based on the characteristics of the philosophy of basic geographical approaches (empiricist, positivist, humanist, and structuralist), the author singled out three dominant concepts: historical-geographical, philosophical-geographical, and political-geographical. Based on these examples and theoretically based on classification of scientific thinking, the author offered a post-structuralist account of the history of geographical thinking. It is based on two assumptions, that there was a strong reception of key ideas from other scientific disciplines (philosophy, social theory, and regional economy) and that geophilosophy can serve as a kind of amalgam that will offer a post-structuralist framework for presenting contemporary geographical thinking. Since a mere presentation of the historical development of modern geography would to a significant extent represent only a bibliographic-encyclopaedic presentation of the development of certain approaches (positivist, humanist, and structuralist), the author combined an evolutionary-historical presentation (analytical method) with an idiographic and nomothetic approach. Thus, a theoretical framework was created which will give this research a synthetic character and which will be applied to socio-geographical studies of the contemporary history of Sarajevo from the point of view of behavioural geography.
CULTURAL HERITAGE OF THE REPUBLIC OF SRPSKA—IDENTITY CODES OF THE PAST, PRESENT, AND FUTURE

The study examines the preservation of the cultural heritage of the Republic of Srpska and its significance for the cultural identity of the region and its community. Cultural heritage serves as a testimony to the past and plays a crucial role in shaping the present and future of society. The study outlines the historical development of the protection system, beginning with the socialist Yugoslav period, during which the first institutions were established and legal frameworks for the systematic protection of cultural heritage were created. The foundations laid during this period remain of key importance today. Contemporary challenges in protecting the cultural heritage of the Republic of Srpska arise from the complexity of Bosnia and Herzegovina’s administrative structure, which is divided into two entities (Republic of Srpska and Federation of Bosnia and Herzegovina) and the Brčko District. This division results in fragmented responsibilities and overlapping jurisdictions across various levels of government, complicating the coordination and implementation of heritage protection laws. The academic community also plays a significant role through its contributions to research, documentation, and the protection of cultural heritage. Furthermore, the analysis provides an overview of development strategies for cultural heritage and spatial planning documentation, which are crucial for preserving heritage. The study comprehensively reviews the current preservation conditions and presents recommendations for improving the protection system. It emphasizes the need for better institutional coordination and more effective legal enforcement to ensure the proper protection and preservation of the cultural values of the Republic of Srpska, which form the foundation of its identity code for future generations.
REVITALISING THE COUNTRYSIDE? ETHNOLOGICAL RESEARCH ON COUNTER-URBANISATION AND RURAL TRANSFORMATION IN BULGARIA

The depopulation of rural areas in Bulgaria is a complex and long-lasting process that began in the mid-20th century. The sizable internal population movements from rural to urban areas in Bulgaria during the communist era led to rapid urbanisation. This was as the result of forced collectivisation and industrialisation. Further rural depopulation was exacerbated by mass emigration abroad in the first two decades of the post-communist transition. This led to a serious deterioration in the demographic, economic, social, and cultural characteristics of rural areas. However, in the last decade, although the general trend of decreasing rural population (and the country’s population in general) has been maintained, the number of movements from rural to urban areas has been smaller than those in the opposite direction. These movements include both returnees to their ancestral villages and new settlers buying rural property. The newcomers also include Bulgarian citizens who have returned from living and working abroad, as well as foreigners who have chosen to settle in Bulgarian villages. The paper aims to provide an overview of the research work on counter-urbanisation in the country that has been carried out by a research team from the Institute of Ethnology and Folklore Studies with Ethnographic Institute and Museum of the Bulgarian Academy of Sciences since 2018. The conceptual framework of the research will be presented. Aiming to investigate the forms and mechanisms of social, cultural, and economic interaction between rural newcomers themselves and with local residents, and how this affects rural transformation, we integrate ethnography with approaches from other disciplines such as social geography, rural sociology, human ecology, policy studies, etc. Key research questions that we address include: What attitudes and prerequisites do locals and newcomers have towards each other? How are different cultural perceptions reconciled in rural settings? How are different knowledge and habits transferred and assimilated? To what extent are compromises made in a diversifying rural environment? What are the potential sources of conflict and what are the strategies for resolving them? How the practices and activities of each group affect the rural landscape and shape the ways in which existing local environments, assets and resources are used.
