Discussions related to land use in Turkey in recent years has been increasing. These discussions are mostly between those who want to protect the natural environment and those who demand other sectoral investment areas. However, there has not been a comprehensive and holistic study assessment of the land use, except for local studies. For this reason, the present study has been conducted in order to reveal the change in land use in the country’s geography. In order to achieve the aims of the study, the literature was reviewed, institutional data were compiled, and the results of previous local studies were evaluated using appropriate methods. Factors affecting land use were examined in the study and it was seen from the findings that significant land use changes occurred in the last 75 years. Although land use suitable for natural structure was common in advance, after the 1980s sectoral needs came to the fore. With the accelerated urbanization and industrialization, tourism, mining and dam areas have become widespread. It has been determined that there is a need for new scientific studies on land use, revision of ineffective laws, and national land use plans that take into account the sectoral needs in order to reduce the discussions. 展开更多

BACKGROUND Monkeypox(Mpox),is a disease of global public health concern,as it does not affect only countries in western and central Africa.AIM To assess Burundi healthcare workers(HCWs)s’level of knowledge and confidence in the diagnosis and management of Mpox.METHODS We conducted a cross-sectional study via an online survey designed mainly from the World Health Organization course distributed among Burundi HCWs from June-July 2023.The questionnaire comprises 8 socioprofessional-related questions,22 questions about Mpox disease knowledge,and 3 questions to assess confidence in Mpox diagnosis and management.The data were analyzed via SPSS software version 25.0.A P value<0.05 was considered to indicate statistical significance.RESULTS The study sample comprised 471 HCWs who were mainly medical doctors(63.9%)and nurses(30.1%).None of the 22 questions concerning Mpox knowledge had at least 50%correct responses.A very low number of HCWs(17.4%)knew that Mpox has a vaccine.The confidence level to diagnose(21.20%),treat(18.00%)or prevent(23.30%)Mpox was low among HCWs.The confidence level in the diagnosis of Mpox was associated with the HCWs’age(P value=0.009),sex(P value<0.001),work experience(P value=0.002),and residence(P value<0.001).The confidence level to treat Mpox was significantly associated with the HCWs’age(P value=0.050),sex(P value<0.001),education(P value=0.033)and occupation(P value=0.005).The confidence level to prevent Mpox was associated with the HCWs’education(P value<0.001),work experience(P value=0.002),residence(P value<0.001)and type of work institution(P value=0.003).CONCLUSION This study revealed that HCWs have the lowest level of knowledge regarding Mpox and a lack of confidence in the ability to diagnose,treat or prevent it.There is an urgent need to organize continuing medical education programs on Mpox epidemiology and preparedness for Burundi HCWs.We encourage future researchers to assess potential hesitancy toward Mpox vaccination and its associated factors. 展开更多

BACKGROUND Arabic-speaking patients are underrepresented in orthopedic clinical studies,particularly in foot and ankle trauma research.The lack of validated Arabic language tools hinders their inclusion,creating a need for culturally and linguistically adapted instruments.The American Academy of Orthopedic Surgeons Foot and Ankle Outcomes Questionnaire(AAOS-FAOQ)is a widely used tool but has not been adapted for Arabic-speaking patients.AIM To translate,cross-culturally adapt,and validate the AAOS-FAOQ for Arabicspeaking patients with traumatic foot and ankle injuries.METHODS The cross-cultural adaptation followed established guidelines,involving forward and backward translations,expert review,and pre-testing.The final Arabic version was administered alongside the Arabic Short-Form 36(SF-36)to 100 patients for validity testing.Reliability was assessed through test-retest methods with 20 patients completing the questionnaire twice within 48 hours.Pearson correlation coefficients measured convergent and divergent validity with SF-36 subscales,while Cronbach's alpha and intraclass correlation coefficients(ICC)determined internal consistency and reliability.RESULTS Out of 100 patients,92 completed the first set of questionnaires.The Arabic AAOS-FAOQ showed strong correlations with the SF-36 subscales,particularly in physical function and bodily pain(r>0.6).Test-retest reliability was robust,with ICCs of 0.69 and 0.66 for the Global Foot and Ankle Scale and Shoe Comfort Scale,respectively.Cronbach's alpha for internal consistency ranged from 0.7 to 0.9.CONCLUSION The Arabic version of the AAOS-FAOQ demonstrated validity and reliability for use in Arabic-speaking patients with traumatic foot and ankle injuries.This adaptation will enhance the inclusion of this population in orthopedic clinical studies,improving the generalizability of research findings and patient care. 展开更多

In a re-examination of the Neogene stratigraphy of the Uşak,Güre,and Selendi basins of western Anatolia,western Turkey,the stratigraphic position of the previously definedİnay Group is revised,which was previously considered to be of the Middle Miocene age.Based on mammalian biochronology and stratigraphic relationships,two sequences are identified,separated by conformable/transitional contacts within the former group:the Middle Miocene Güre Group is composed of the FakılıFormation,characterized by alluvial fan deposits,and the lacustrine Derbent Formation.Radiometric dating of alkaline volcanics laterally associated with Güre Group sediments in the Uşak and Güre basins,and mammalian fossils re-evaluated into the MN5-6 biozones in the Selendi Basin,indicate early Middle Miocene.Considering the stratigraphic relationship with the overlying early Late Mioceneİnay Group as redefined,we estimate that the Güre Group was deposited in the Middle Miocene.Theİnay Group is characterized by a lateral-vertical transition from alluvial deposits of the Ahmetler Formation to the overlying lacustrine Ulubey Formation.An MN9-10 fauna,containing deinotheres,was found within the latter formation. 展开更多

Introduction: The WHO’s measles control strategy is based on epidemiological surveillance and vaccination. Little is currently known about the performance of the surveillance system, particularly in outlying areas. It is in this context that the present study was carried out to evaluate the measles epidemiological surveillance system in the Kangaba health district. Method: This was a descriptive cross-sectional study with retrospective data collection for the period from 1 January to 31 December 2022 in the Kangaba health district with 18 epidemiological surveillance officers. Data were collected using an observation grid and documentary analysis. Results: We found a simplicity of 97%, a representativeness of 95% and a reactivity of 53%. Not all notified cases were sampled (64%). Of the 17 CSCom, 8 were positive. A total of 34 confirmed cases of measles were recorded, with one death. Conclusion: Overall, the system is functional and well-established in the health centres, but it remains important to ensure that suspected cases are investigated and that the time between sampling and the availability of laboratory results is respected. 展开更多

Aluminum alloys are widely used in industry due to their light weight.These alloys are generally exposed to abrasive wear,which diminishes their effective lifespan.The wear resistance of these alloys is enhanced by adding various reinforcements,however,this enhancement comes at the cost of reduced fracture toughness.This paradox of increased wear resistance versus decreased fracture toughness in aluminum alloys can be resolved by using functionally graded materials (FGMs).This study focuses on the abrasive wear behavior of functional graded aluminum matrix composites reinforced with Al_(3)Ti particles.The wear properties of the composites were investigated by considering the characteristics of the composite such as matrix type and various composite zones,as well as the wear parameters such as abrasive particle diameter,load,sliding speed and distance.Taguchi method was used in the abrasive wear tests in order to get more reliable results in a timeefficient manner.Experiment recipes were created based on the L_(27)(3^(6)) orthogonal series.As a result of the study,it is observed that the wear resistance of the composites increases with an increase in Al_(3)Ti reinforcement content and hardness of the matrix.In addition,the size of abrasive particles and the applied load are significant factors affecting abrasive wear. 展开更多

Climate change-driven environmental stresses,particularly ultraviolet-B(UV-B)radiation,pose severe threats to grapevine(Vitis vinifera L.)productivity and physiological stability.This study investigated the protective role of melatonin in in vitro plantlets of two grapevine cultivars,‘Merlot’and‘Erci¸s’,subjected to low(≈8.25μWcm^(−2),16 h)and high(≈33μW cm^(−2),4 h)UV-B exposure.Significant cultivar-specific responses were observed(p<0.001).The‘Erci¸s’cultivar exhibited higher oxidative stress,with malondialdehyde(MDA)levels reaching 24.30 mmol g^(−1)FW in control plants compared with 14.91±0.25 mmol g^(−1)FW in‘Merlot’.Melatonin provided dose-dependent mitigation,reducing MDA to 12.68 in‘Erci¸s’and 8.52±0.13 in‘Merlot’at 200μmol L^(−1).Antioxidant enzyme activities increased significantly:superoxide dismutase rose from 0.02±0.01 to 0.10 EU g^(−1)in‘Erci¸s’and to 0.13 EU g^(−1)in‘Merlot’,catalase increased up to 0.08 in‘Erci¸s’and 0.16 in‘Merlot’,while ascorbate peroxidase reached 1.06±0.02 and 1.20±0.03,respectively.Pigment traits also improved,with chlorophyll content increasing to 23.70μg cm^(−2)in‘Merlot’and 22.66μg cm^(−2)in‘Erci¸s’,alongside enhanced nitrogen balance index values.Secondary metabolites were elevated,particularly total phenolic content(8.23 GAE 100 g^(−1)in‘Erci¸s’and 5.99 in‘Merlot’)and antioxidant capacity(17.24 and 8.15μmol TE g^(−1),respectively).Correlation analyses revealed strong positive associations betweenmelatonin and antioxidant enzymes(r=0.54-0.85),while principal component analysis explained 64.71%of total variance,separating cultivars and treatments clearly.Clustering patterns showed distinct grouping of enzymatic defenses,phenolic compounds,and pigments,reflecting coordinated protective mechanisms.Overall,melatonin application,especially at 200μmol L^(−1),significantly enhanced enzymatic and non-enzymatic antioxidant defenses,stabilized photosynthetic pigments,and reduced oxidative damage,with stronger protective efficiency in‘Merlot’.The research provided valuable insights for developing biotechnological approaches to enhance grape stress tolerance in the context of climate change challenges. 展开更多

Turkey is highly prone to landslides because of the geological and geographic location.The study area,which is located in a tectonically active region,has been significantly affected by mass movements.Flow type landslides are frequently observed due to this location.This study aims at determining the source area and propagation of debris flows in the study area.We used the heuristic method to extract source areas of debris flow,and then used receiver operating characteristic(ROC)curve analysis to assess the performance of the method,and finally calculated the Area under curve(AUC)values being 83.64%and 80.39%for the success rate and prediction rate,respectively.We calculated potential propagation area and runout distance with Flow-R software.In conclusion,the obtained results(susceptibility map,propagation and runout distance)are very important for decisionmakers at the region located on an active fault zone,which is highly prone to natural disasters.The outputs of this study could be used in site selection studies,designing erosion prevention systems and protecting existing human-made structures. 展开更多

Fluorite mineralization occurs along fractures and cracks of Middle Eocene and Pliocene limestones and marls in the north and northeast of the P?hrenk region (?i?ekdagi, Kirsehir). Tb/Ca – Tb/La and Y/Ho ratios were obtained from REE contents of fluorites which have revealed that mineralization is of hydrothermal type. Negative Ce anomalies and positive Eu anomalies reflect that hydrothermal solutions once had high oxygen fugacity. Fluid inclusion studies indicate that homogenization temperatures of mineralization varied between 90°C and 200°C, and hydrothermal solutions are composed of NaCl + KCl + MgCl2 + H2O. In addition, salinity measurements show that hydrothermal solutions were mixed with meteoric or rock formation water. Geologic setting, REE geochemistry and fluid inclusion studies suggest that mineralization was deposited from a solution generated by mixing of magmatic and meteoric water under epithermal conditions. 展开更多

The objectives of this study were:(1)to determine carbon stock changes in the soil and forest floor of black pine(Pinus nigra subsp.pallasiana)plantations in Turkey;(2)to determine the effects of thinning on annual carbon accumulation in both;and,(3)to investigate relationships between annual carbon storage in soil and forest floor and stand characteristics of black pine.Samples were taken in 90 plots from stands at the pole(dbh=11.0–19.9 cm)and sawlog(dbh=20.0–35.9 cm)stages.Carbon analyses of soil and forest floor samples showed that in unthinned plantations signifi cant organic carbon was sequestered an average of 1.47 Mg ha^−1 a^−1 in the soil and 0.20 Mg ha^−1 a^−1 in the forest floor.Organic carbon sequestered annually in the soil was signifi cantly lower in thinned than in unthinned stands,while diff erences in the forest floor were insignifi cant.There were positive correlations between carbon sequestered in the soil and stand age,average DBH,mean stand height,basal area,and site index.Carbon sequestered the forest floor increased with basal area.As a result,carbon sequestered in the soil should not be ignored in greenhouse gas inventories because carbon stored belowground was approximately 70%of the aboveground pool. 展开更多

Internet of Vehicles(IoV)is a new style of vehicular ad hoc network that is used to connect the sensors of each vehicle with each other and with other vehicles’sensors through the internet.These sensors generate different tasks that should be analyzed and processed in some given period of time.They send the tasks to the cloud servers but these sending operations increase bandwidth consumption and latency.Fog computing is a simple cloud at the network edge that is used to process the jobs in a short period of time instead of sending them to cloud computing facilities.In some situations,fog computing cannot execute some tasks due to lack of resources.Thus,in these situations it transfers them to cloud computing that leads to an increase in latency and bandwidth occupation again.Moreover,several fog servers may be fuelled while other servers are empty.This implies an unfair distribution of jobs.In this research study,we shall merge the software defined network(SDN)with IoV and fog computing and use the parked vehicle as assistant fog computing node.This can improve the capabilities of the fog computing layer and help in decreasing the number of migrated tasks to the cloud servers.This increases the ratio of time sensitive tasks that meet the deadline.In addition,a new load balancing strategy is proposed.It works proactively to balance the load locally and globally by the local fog managers and SDN controller,respectively.The simulation experiments show that the proposed system is more efficient than VANET-Fog-Cloud and IoV-Fog-Cloud frameworks in terms of average response time and percentage of bandwidth consumption,meeting the deadline,and resource utilization. 展开更多

This is a review article based on literature (national and international) and empirical approach. A general overview on research priority areas on biodiversity and approaches and tools to provide information for forest policy implementation on biodiversity are briefly summarized. Challenges for biodiversity research and related policy in Europe and Greece are depicted. General information on forests, protected areas and forest management in Greece is also presented. Major actions and measures for conservation of forest biodiversity in Greece are described and analysed.
