Published: April 2024

There are many natural products in the environment that influence other organisms. How nervous systems sense these compounds to initiate a behavioral response remains an active area of chemical ecology research. We developed a Course Undergraduate Research Experience (CURE) utilizing Caenorhabditis elegans chemotaxis assays to test how ant compounds are detected by heterospecific nervous systems. These experiments can be conducted in an undergraduate laboratory course, where new insights into interspecies interactions can be generated through genuine research experiences in a classroom setting.

Objective. To verify the association between reproductive autonomy and sociodemographic, sexual, and reproductive characteristics in Quilombola women (a term indicating the origin of politically organized concentrations of Afro-descendants who emancipated themselves from slavery). Methods. Cross-sectional and analytical study with 160 women from Quilombola communities in the southwest of Bahia, Brazil. Data were collected using the Reproductive Autonomy Scale and the questionnaire from the National Health Survey (adapted). Results. Out of the 160 participating women, 91.9% declared themselves as black, one out of every three were aged ≤ 23 years, 53.8% were married or had a partner, 38.8% had studied for ≤ 4 years, over half (58.1%) were unemployed, only 32.4% had a monthly income > R$ 430 (80 US dollars), 52.5% had their first menstruation at the age of 12, 70.7% had not accessed family planning services in the last 12 months, and over half used some method to avoid pregnancy (59.0%). The women had a high level of reproductive autonomy, especially in the "Decision-making" and "Freedom from coercion" subscales with a score of 2.53 and 3.40, respectively. A significant association (p<0.05) was found between the "Total reproductive autonomy" score and marital status, indicating that single or unpartnered women had higher autonomy compared to married or partnered women. Conclusion. The association of social determinants of health such as marital status, education, and age impacts women's reproductive choices, implying risks for sexual and reproductive health. The intergenerational reproductive autonomy of Quilombola women is associated with sociodemographic and reproductive factors.
God of Justice and Reconciliation?
Authors: Punt Jeremia
Published: April 2024

Justice and reconciliation are central concepts in the NT, in explicit and implicit ways, and the terms and their usage often betray their Jewish origins and setting. As the ultimate author of justice and reconciliation, God also expects as much from God’s followers, and ultimately from and towards the cosmos. Mindful that their encompassing reach may lead to semantic inflation, justice, and reconciliation in themselves – but particularly as divine attributes – need to be plotted over a broader spectrum that may have been the case in the past, and with much more attention to these notions in their particular first century context.

Introduction. Health science students represented a particularly vulnerable group during the pandemic. Studies in various regions have found a high prevalence of psychopathology, associated with the presence of stressors such as contact with patients, isolation, and financial difficulties. Objective. To determine the stressors for and frequency of depression, anxiety and substance use in Latin American health science students during the COVID-19 pandemic. Method. A questionnaire-based, cross-sectional study was conducted to measure the presence of stressors and determine anxiety and depression symptoms through the PHQ-9 and the GAD-7 scales, and substance use in 777 students from ten countries, from June 2020 to January 2021. Results. The most frequent stressors were having a loved one diagnosed with COVID-19 and being diagnosed with another illness. A total of 54.1% of the sample had depression, and 46.2% had anxiety according to the rating scales cut-off points, while 24.8% reported substance use. Reading or listening to news about the pandemic was the main stressor associated with the presence of psychopathology. Discussion and conclusion. Latin American health science students displayed high frequencies of psychopathology associated with various stressors. It is therefore important to monitor the mental health of this population to prevent low academic performance.
Improved Surrogacy Regressions for Clinical Trial Endpoints in Relapse/Refractory and Newly Diagnosed Multiple Myeloma
Authors:   , Butler Rhys Jonathan , Alvarez Nicolas J.
Published: April 2024

Use of surrogate endpoints such as objective response rate (ORR) and progression-free survival (PFS) is common in multiple myeloma (MM) risk-benefit modelling for treatment approval, and notably accelerated approval. Yet, there is conflicting evidence supporting their surrogacy between themselves and overall survival (OS). This systematic review characterises all published single arm trials and randomised controlled trials (RCTs) in MM using ORR, PFS, TTP and OS endpoints between 1999 and 2022 (databases provided in supplemental information), and assesses the strength of surrogacy between each relationship, to determine if current data can support improve estimations for survival endpoints. The regressions were evaluated with the coefficient of determination with Pearson's correlation, and the F-test was used in cases of multivariate regressions. The analysis demonstrated that current regressions overpredict survivability endpoints, but there are multivariate models that can accurately predict clinical outcomes with patient characteristics and surrogate endpoints for both RRMM and NDMM.

Published: April 2024

Primary ciliary dyskinesia (PCD) is a rare hereditary disease, a ciliopathy that is based on a defect in the ultrastructure of the cilia of the epithelium of the respiratory tract and similar structures. All parts of the respiratory tract are affected. About half of the patients with PCD have transposition of the internal organs (Kartagener syndrome – KS).

The aim was to investigate the clinical and genetic characteristics of patients with PCD with and without KS.

Methods. An assessment of clinical and genetic characteristics was performed in a sample of 127 patients with PCD, who were divided into 2 groups: patients with KS (n = 60) and without KS (n = 67). The groups were compared on the basis of their medical history (according to the PICADAR scale), clinical, instrumental and laboratory data, including the results of light and video microscopy, transmission electron microscopy (TEM) and genetic testing.

Results. According to the results of comparative characterization of patients with PCD with and without KS, there were similarities in the medical history, decreased lung function indices, videomicroscopy results – ciliated epithelium beating below 6 Hz, TEM – predominance of dynein arm defect. The PICADAR score was higher in the group with KS than in the group without it; congenital heart defects and renal pathology were found more frequently in patients with KS, while hearing loss and nasal polyposis were found more frequently in patients without KS. Electron microscopy revealed defects in the outer and inner dynein arms of the cilia in 50% of patients in both groups, and a tendency to lack of the central pair of microtubules in 18% of patients without KS. The following genes responsible for PCD were found in both groups: DNAH5, CFAP300 and HYDIN. DNAH5 gene variants were more common for KS patients (61.1%), while HYDIN gene variants were only found in patients with PCD without KS (15.8%).

Conclusion. The identified differences may help in the diagnosis of the groups studied.

Authors: Krylova N. A. , Amelina E. L. , Krasovsky S. A. , Shumkova G. L.
Published: April 2024

Cystic fibrosis (CF) is characterized by the development of a severe nutritional deficiency. A low BMI directly correlates with low lung function and requires active nutritional support. Pathogenetic (targeted) therapy aimed at restoring the chlorine channel function also leads to weight gain. The effects of CFTR modulators on extrapulmonary pathology in adult CF patients in Russia have been described very little.

Aim. To evaluate the sequential impact of two targeted drugs – the potentiator ivacaftor and the triple combination of CF transmembrane regulator modulators elexacaftor/tezacaftor/ivacaftor – on the nutritional status of an adult patient with cystic fibrosis receiving nutritional support.

Conclusion. Therapy with CFTR modulator in combination with sipping nutritional support promotes significant weight gain in adult CF patients. The triple combination of elexacaftor/tezacaftor/ivacaftor has a more active effect on nutritional status than ivacaftor alone. The targeted therapy requires supervision by a nutritionist.

Published: April 2024

Background: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) has proven effective in boosting bystander CPR rates in out-of-hospital cardiac arrests (OHCA). Recently, Thailand has implemented a DA-CPR program. Our objective was to delineate the obstacles to initiating chest compressions by callers.
Methods: We reviewed dispatch recordings of OHCA cases received by the ambulance call center from July 2012 to March 2015. Excluding audio recordings of subpar quality, trained evaluators documented the successive stages of the dispatcher's CPR recognition, delivery of CPR instructions, and the caller's execution of CPR. The time required to achieve these milestones was recorded, while barriers hindering chest compressions were identified.
Results: Throughout the study period, researchers identified 280 cases of OHCA. Among these cases, it was observed that 134 bystanders declined to administer CPR. Reasons for refusal varied: 25.4% cited difficulty in controlling their emotions, 21.65% encountered challenges accessing the scene, 20.9% refused to perform CPR, 14.9% dropped out of the call, 9.7% did not approach the emergency patient, 5.9% were unable to perform CPR due to physical limitations, and 2.9% faced difficulty moving the emergency patient to the ground floor.
Conclusions: Barriers were present in 47.85% correlating with a reduced proportion of CPR initiation and longer delays in CPR initiation.

Authors: Ilambarathi M. , Yeolekar Aditya , Roy Dhrubo , Saxena Savyasachi , Kumar Suresh
Published: April 2024

Background: Prochlorperazine is commonly used for managing vertigo and dizziness-associated vestibular disorders. This study was designed to evaluate the effectiveness and safety of prochlorperazine in Indian patients with vestibular migraine.
Methods: In this prospective, multicenter, open-label, single-arm study, VM patients received 5 mg of prochlorperazine thrice daily for 5 days. The primary endpoint measured changes in clinical response using the scale for vestibular vertigo severity level and clinical response evaluation from baseline to days 6, 15, and 30. Secondary endpoints included symptom severity improvement and changes in SVVSLCRE from baseline up to day 30. Safety and tolerability were also assessed. Statistical analysis used the Wilcoxon signed-rank test and student-paired t-test.
Results: Out of 259 enrolled patients, 254 (98.1%) completed the study with a mean (standard deviation) age of patients was 42.22 (10.7) years; 72.2% were females. Significant improvements in clinical response and symptom severity were observed at all follow-up periods. 81.5% of patients showed VM symptom improvement by day 6, with 77.2% exhibiting moderate to good changes in SVVSLCRE scores. 83.4% experienced milder vestibular symptoms after 6 days. Furthermore, a significant difference (p<0.001) in mean values was observed from baseline at different follow-up periods. 11 (4.3%) adverse events (AEs) were reported, with headache being the most common (2, 0.8%); all AEs were unrelated to the study drug, and patients reported good tolerability.
Conclusions: Prochlorperazine showed significant improvement in clinical response and symptom severity with acceptable safety and tolerability in VM patients.
Post-therapeutic detection of local tumor persistence of head and neck cancer: the value of routine control endoscopy with biopsy and medical imaging
Authors: Engert Tobias , Acu Leyla , Schoenhofer Johann , Rommers Nikki , Ahmad Nader
Published: April 2024

Background: Insufficient local tumor control is the main cause of treatment failure in head and neck cancer (HNC). Re-staging HNC is challenging because of post-therapeutic tissue distortion. We investigate whether medical imaging and biopsy is more sensitive in identifying tumor persistence.
Methods: In our clinic a re-staging with a control endoscopy and medical imaging is performed 3 months after therapy for some HNC patients. In this retrospective study, we compare the accuracy of imaging to the histology (gold standard). Imaging reports were classified according to 3 scales and re-assessed by 2 neuroradiologists. Furthermore, we evaluate recurrence rates and disease-free survival.  
Results: 100 cases were evaluated. 14 patients presented with positive histology at the re-staging. Biopsy detected malignancy in 7 patients with inconspicuous imaging. Disease-free survival during the first 2 years was generally low (n=55). The accuracy of the RECIST scale was 0.74 with a sensitivity of 0.50 and a specificity of 0.78. Imaging reports reviewed according to the Lee-scale and a self-developed scale presented an accuracy of 0.47 and 0.51. Re-assessment of imaging by 2 neuroradiologists showed an accuracy of 0.87.
Conclusions: Medical imaging alone serves as a moderate diagnostic tool to diagnose local persistence of HNC 3 months after therapy. Radiologic misdiagnosing can be addressed by control endoscopy. Our results indicate a benefit of routine biopsies since reliance on imaging may fail to notice tumor persistence. A binary classification of imaging showed a higher accuracy than conventional imaging scales and may help to predict tumor recurrence within 24 months after re-staging.

Published: April 2024

Background: This study assesses the mid-term clinical and functional outcomes, implant survivorship and impact of age on patients implanted with either cruciate retaining/posterior stabilized (CR/PS) total knee system (TKS).
Method: This is an ongoing, prospective, multicentre, real-world study enrolling 300 patients: younger adults (<55 years; n=69), older adults (55 years to <65 years; n=92) and elders (≥65 years; n=139). Primary safety endpoints: implant survivorship and cumulative revision rate. Secondary endpoints: Knee Society Score (KSS), Western Ontario and McMaster universities osteoarthritis (WOMAC) score, range of motion (ROM), SF-36 questionnaire for assessment of quality of life (QoL), radiographic analysis, and any adverse events at 6 weeks, 6 months, 1-3 years. 
Results: Primary endpoint demonstrated absence of any revision across all age categories during the 3 years study period. Secondary outcomes KSS (clinical and functional) showed non-significant difference among elderly (91.13±7.90 and 98.18±4.62, respectively) in comparison to young adults (91.03±8.61 and 98.91±3.75, respectively). All three age-groups showed significant improvement in ROM (p<0.001) till 3 years 121.05°±7.74°, 123.22°±4.26°, and 122.43°±5.8° respectively, with no differences among the age groups. We observed that WOMAC and SF-36 QoL scores improved with each follow-up (p<0.001) across all age groups. Radiographs showed no implant wear or osteolysis during the investigation.
Conclusions: Age seems to play no notable role on the post-TKA outcomes. Over a 3-year period, we observed marked enhancements in patient measures such as ROM, KSS, WOMAC, and QoL indicating and strongly affirming the safety and efficacy of CR/PS TKS prostheses.
The Pragmatic Principles in the Grammar Descriptions
Authors: Borisova Elena
Published: April 2024

The text of the article is dedicated to the development of means of describing grammatical categories. In the first place, attention is paid to categories that are capable of conveying nominative, or lexical, meaning, such as the category of number which conveys the opposition of meanings "one" and "many". In Russian grammar, the rules for the use of the grammatical category of verb aspect are considered the most complex case. The semantic component of this category is contradictory and requires a large conceptual apparatus. However, even in this case, not all cases of real use of aspectual forms receive a consistent interpretation. Many "difficult cases" can be reinterpreted with the help of new concepts related to modeling speech activity. The article demonstrates the possibility of using pragmatic tools, in particular Grice's postulates and the principle of relevance, to describe the most complex fragments of the language system. An attempt is made to analyze the most complex cases of the use of Russian verb aspect, which is not always reduced to the opposition of completed and incomplete action. Cases of competition - context in which the choice of aspect is not related to the main aspectual meanings, causing difficulties in learning Russian - are meant. Examples are described where the choice of aspect can be explained by the speaker's desire for clarity and comprehensibility in accordance with pragmatic principles. This approach - interactive, i.e. considering the interaction between speaker and listener - allows not only to formulate rules for choosing aspect in cases noted in practical textbooks, but also to explain why the rules from textbooks may not work, not predict the real correct use of aspectual forms.

Authors: Kulpina Valentina
Published: April 2024

The article concerns the means of expressing politeness of the Speaker in Slavic languages: Russian, Polish (the most detailed description), Check, Bulgarian and Macedonian. The aspects of study of the forms of politeness and the names of politeness types, precise from the point of view of thought and form are analyzed. The forms of politeness of Slavic languages are considered comparatively with the forms of politeness of Japanese language as they are presented in the works of V.M. Alpatov. V.M. Alpatov worked out the theory of Japanese forms of politeness which is useful for the researches of etiquette in the Slavic languages and it is showed in the article. Changing in the rules of the politeness, caused by the democratization of communication, is also mentioned. The connections between rules of the politeness and the mentality of Slavic nations are revealed. The categorical specificity of forms of politeness in different Slavic languages is showed. The material is analyzed from the point of view of presence / absence of some parameters in above mentioned Slavic languages. There is underlined that the forms of politeness are for native speakers natural and organic; their structure and hierarchy they do not observe and reflect. The didactic aspects of the subject are analyzed as very important ones.
Utópia és társadalomtudomány – Értelmezés a Fahrenheit 451 című könyv nyomán
Authors: Dudik Benedek
Published: April 2024

Utopian and dystopian works have traditions hundreds of years, but their golden era did not begin until the 20th century. The genre is very often depicted as a literary genre, but in reality it is much more than simple fiction. These novels are as much social science and social theory writings as they are works of phantasmagoria. In my writing, I strive to explain this line of thought based on Ray Bradbury’s 1953 novel Fahrenheit 451. In the course of my work, following the fictional story of Guy Montag, I intend to present the peculiarities of the genre, its social science relations and its relationship with our contemporary society, in parallel with other dystopian works of the 20th century.
Utilizing Polyethylene Terephthalate (PET) In Insulation Fired Clay Bricks
Authors: ELDEEB Ali
Published: April 2024

In order to improve the thermal insulation properties of fired clay bricks, the addition of polystyrene has been a common practice. However, in this study, we propose an alternative approach by substituting polystyrene with recycled polyethylene terephthalate (PET) derived from drinking water bottles. The PET is shredded and added to the brick composition, with a maximum inclusion level of 25%. Various tests were conducted to evaluate water absorption, apparent porosity, bulk density, cold crushing strength, and thermal conductivity of the bricks at temperatures up to 800 degrees Celsius. The results indicate that incorporating 20% crushed plastic by weight yields bricks comparable to ASTM C155-97 standard bricks.

Published: April 2024

Since the advent of modern technology, accelerated by the COVID-19 pandemic, open distance learning (ODL) has become increasingly popular. ODL has emerged as a flexible mode of education that allows learners to collaborate online, breaking down geographical barriers. In the context of ODL, incorporating collaborative learning strategies has gained significant attention due to its potential to enhance the quality of education and foster a sense of community among learners. Cooperative learning in ODL is a pedagogical approach that encourages learners to actively engage with their peers, instructors, and course materials to construct knowledge. It leverages various technologies and online platforms to facilitate interactions among learners, creating a virtual classroom that transcends geographical boundaries. This systematic literature review provides insights into past studies on collaborative learning strategies, focusing on students' interest and motivation, retention, and achievements. The analysis of existing ODL practices aims to highlight the benefits and drawbacks of collaborative learning strategies in ODL. The results of this research contribute to our understanding of effective teaching methodologies in ODL. Additionally, it underscores the pressing need for innovative solutions to address the challenges of fostering collaboration among students.

A landfill is a site to dispose of materials that threaten the environment, such as leachate, poisons, or greenhouse gases. Leachate is a liquid that can contribute to water pollution if there is a leakage of flow into groundwater sources from landfill waste or other outside water sources. Leachate is a liquid accumulated from landfill waste and other outside water sources. To prevent this leachate from mixing with water resources when it flows into the soil, the behavior of Kenaf (Hibiscus Cannabinus) as a landfill liner system is investigated and understood thoroughly on how permeability properties can increase with the soil. In addition, the herbaceous plants known as Kenaf have beneficial mechanical properties, and they do not pose any threat to the health of human beings. Kenaf has significant potential for commercial usage because of the ease with which it can be cultivated and the low prices at which it can be harvested. In addition, Kenaf can contribute to infrastructure and innovation for economic growth and development (SDG 9.0), where it can reduce the usage of clay linear and simultaneously, increase the Permeability of the soil properties to resist the flow of leaches into the soil. This admixture is gaining popularity as a result of the fact that it has a relatively low cost and is simple to apply. In this investigation, Kenaf was used because of its reputation as a good absorbent product that can hold up to six times its weight and has a leaching capability of less than one percent. The results of laboratory work are presented to demonstrate that this material is suitable for usage in landfills to solve the leachate problem.
Structural and dielectric properties of Eu3+,B3+ co-doped CoNb2O6 ceramic
Authors: İlhan Mustafa , Ekmekci Mete Kaan , Esmer Kadir
Published: April 2024

The boron co-doped CoNb2O6:xEu3+, yB3+ (x=1, 3, 6, 9, 12 mol%, y=10 mol%) ceramics were obtained by the molten salt method, which has advantageous properties such as short reaction time, low sintering temperature, improved homogeneity, and crystallinity. The ceramic samples were examined by structural and dielectric analyses. In X-ray diffractions, the orthorhombic columbite type CoNb2O6 structure was obtained, and also a minor EuNbO4 phase was detected with increasing Eu3+ doping concentrations. Additionally, increasing Eu3+ concentration led to a slight increase in crystallite size, and two theta peak shifts occurred towards higher angles associated with shrinkage in the lattice or reduction in the lattice constant. In SEM examinations, a slight increase was observed in grain sizes from 1 to 9 mol% Eu3+ in the range of 1-30 m, while some decrease occurred in grain sizes at 12 mol%, and there was an evident increase in plate-shaped and elongated grains. The dielectric constant (ε') of the ceramic samples increased with increasing Eu3+ concentration and reached approximately 35 and 0.24 at 20 Hz for 9 mol% Eu3+, respectively. The increase in dielectric loss with increasing Eu3+ was associated with an increase in ionic conductivity, in which Eu3+ substitution does not suppress oxygen vacancies or make them more ordered.

Authors: Mejía Ríos Jennifer , Sepulveda Casadiesgo Yulian Adalberto , Díaz Téllez Ángel Saúl
Published: April 2024

La transdisciplinariedad emerge como una herramienta clave para enfrentar la complejidad del mundo académico y social contemporáneo. Esta reflexión tuvo como orientación el objetivo: examinar desde lo bibliográfico la influencia de la perspectiva transdisciplinar en la investigación social y educativa, considerando su énfasis en la complejidad y los desafíos asociados. Mediante una metodología que integra paradigmas filosóficos y epistemológicos, se lleva a cabo una búsqueda extensa en bases de datos académicas, y se aplica un análisis avanzado con el software Atlas.ti, basándose en el marco ReSiste-CH de Condina (2020). Uno de los hallazgos centrales identifica a la metáfora como una herramienta indispensable en la construcción del conocimiento transdisciplinario. En el artículo se revela cómo la transdisciplinariedad puede influir en la formación de pensadores futuros. A pesar de la profunda visión desde la mirada de los transdisciplinar, se reconoce una orientación principalmente académica en el estudio, lo que podría limitar perspectivas más amplias. En el análisis, se consideran los principios de Alan Sokal y Jean Bricmont como esenciales para alcanzar la transdisciplinariedad en la investigación. En conclusión, la transdisciplinariedad, pese a sus retos inherentes, representa una oportunidad para adquirir un conocimiento enriquecido. Esta reflexión insta a la comunidad académica a superar las barreras tradicionales y a valorar la interconexión del conocimiento en un mundo dominado por la complejidad.

On 23rd December, hardly a day away from Christmas eve celebrations in Kenya, the capital city of Nairobi was pounded by a rain storm for a good 20 minutes after which, there were reports of uprooted trees which had fallen on vehicles killing people and on houses. The 20-minute disruption blocked roads and blew up electricity transmitters, causing many Kenyans to go without electricity and associated Christmas celebrations and even carols. For many households, no electricity for two days meant food beginning to go bad and no internet for those who wished to send Season’s greetings, or just to go on working.

Developing Multi-disciplinary Capacity for Agriculture, Health and Nutrition - Challenges and Opportunities
Authors:   International Food Policy Research Institute, Babu Suresh
Published: April 2024

It is increasingly recognized that the ultimate goal of agriculture is nutrition and health of the population. Yet, linkages among these sectors in designing and implementing programs and policies that complement and reinforce their goals remain weak. This is largely due to inadequate capacity to address challenges faced jointly by these sectors. Low levels of individual sector capacities add to the burden of developing multi-disciplinary capacity to address policies and programs that will have implications for the related sectors and thwart achieving the full nutrition and health benefits of agriculture in many developing countries. Yet, serious efforts to develop such multi-disciplinary capacity in Africa remain limited.

Published: April 2024

The article presents the problem of particulate matter and heavy metal emissions from the tribological systems (road abrasion, brake and tyre wear) road of cars equiped with internal combustion engines (ICEs), battery electric vehicles (BEVs), hybrids and plug-in vehicles (PHEVs). The results of mathematical modelling carried out for obtaining of the emissions of particulate matter and heavy metals, such as As, Cd, Cr, Cu, Ni, Pb, Se and Zn, resulting from the road abrasion, brakes and tyre wear, are presented. Emissions are shown depending on the average speed and type of traffic (traffic in the city (urban), outside the city (rural) and on the highway) and the type of vehicle.

The article carries out a detailed analysis and evaluation of indicators related to the combustion process (pressure and temperature in the engine combustion chamber, heat release rate, heat release fraction) in a JCB 444 TA4i compression-ignition engine fuelled with diesel and hydrogenated vegetable oil (HVO). During the empirical tests, the operation of the exhaust gas recirculation (EGR) system was stopped and no other changes were made to the engine settings (factory settings were used). In the first stage, the empirical tests were carried out at speed characteristics on an engine dynamometer. Then, an experiment was carried out at the engine crankshaft speed corresponding to the maximum torque - which consisted of determining the indicators related to the combustion process at a constant mass flow of fuel: diesel and HVO fuel. This provided information on the effect of hydrogenated vegetable oil on the combustion process in relation to the diesel engine feed. The conclusions drawn from the empirical study can be used to develop guidelines to change the operating map of a compression-ignition engine when it is fed with hydrogenated vegetable oil.
CUMHURİYET DÖNEMİNDE DEPREMLERLE MÜCADELEDE KAMU POLİTİKALARININ ROLÜ

Published: April 2024

Türkiye coğrafi konumu ve yer şekilleri itibariyle afetlerin sık yaşandığı bir bölgedir. Geniş yüzölçümü nedeniyle aynı anda farklı coğrafi olaylar bir arada yaşanabilmektedir. Ayrıca nispeten genç jeolojik yapısı nedeniyle sıklıkla depremler yaşanmaktadır. Depremler ciddi can ve mal kayıplarına neden olmaktadır. Bu çalışmada cumhuriyetin ilanından bugüne Türkiye’de yaşanan depremler ve depremlerle mücadelede uygulanan kamu politikalarının neler olduğu Resmi Gazetede yayımlanmış şekliyle ele alınarak analiz edilecektir. Çalışmada içerik analizi yönteminden yararlanılmıştır. İçerik analizi yönteminde Resmi Gazetede deprem, zelzele ve sarsıntı kelimeleri ayrı ayrı arama kısmına yazılmıştır. Toplamda 402 başlıkta bu kavramların geçtiği düzenlemelerin yapıldığı görülmüştür. Çalışmada dönemsel ayrım 7 ve üzerinde şiddette depremlerin yaşandığı dönemlere göre yapılmıştır. Buna göre beş farklı döneme ayrılmıştır. Dönemler itibariyle belli spesifik ve genel düzenlemelerin yapıldığı görülmüştür. Zaman içerisinde depremlerle mücadelede belli bir olgunluğa erişilmişse de esasında can ve mal kayıplarının sayısı henüz istenilen seviyelerde olunmadığını göstermiştir. Depremlerle mücadelenin en önemli unsurları; uluslararasılaşma, katılım ve kurumsallaşma ve koordinasyondan oluşmaktadır. Türkiye’de kurumsal anlamda bir ilerleme kaydedilmiştir. Vatandaşların güveninin henüz istenilen noktada olmamasından dolayı katılımın da istenilen seviyelerde olmadığı görülmüştür. Kahramanmaraş Depreminde MTV iptali için Anayasa Mahkemesine başvurulması buna örnek olarak gösterilebilir. Deprem tecrübesi yüksek olan ülkelerden yeterince istifade edilemediği son depremdeki can kayıplarından anlaşılmaktadır. Koordinasyon konusunda da AFAD’ın sadece depremle ilgili değil deprem dışındaki işlerle de ilgilenmesi bir eksiklik olarak değerlendirilebilir. Çalışmada deprem ve kamu politikaları konusunda çalışma yapacak olanlara yardımcı olmak açısından literatür oluşturulması, ayrıca deprem konusunda daha önce yapılmış olan düzenlemelerden yararlanılarak gelecekte eksik görülen hususların tamamlanması konusunda politika yapıcılara yol gösterici öneriler sunulması hedeflenmektedir.
