Dünyanın varoluşundan itibaren çeşitli periyotlarda iklim değişikliği ile karşı karşıya kalan yeryüzü, özellikle Sanayi Devrimi’nden itibaren insanların doğayı tahakküm altına almaları sonucunda insan kaynaklı nedenlerle ilk kez ortaya çıkmıştır. Sanayileşme ve kentleşme, fosil yakıtların kullanımının aşırı artışı, ormansızlaşma gibi nedenler sonucunda sera gazlarının atmosferde birikerek iklimlerin düzenini değiştirmesi olarak ifade edilen iklim değişikliği, küresel bir boyuta ulaşarak canlı ve cansız tüm varlıkların geleceğini tehdit etmektedir. İklim değişikliğinin yeryüzünde sel ve taşkınlar, kuraklık, yağış rejimlerinin düzensizleşmesi, salgın hastalıklar, zorunlu yer değiştirmeler gibi çok sayıda olumsuz etkisinin yanında insan sağlığı üzerinde de birçok zararı olduğu bilinmektedir. Can kayıpları; kalp, damar ve akciğer rahatsızlıkları; bebek ölümleri ve psikolojik rahatsızlıklar, iklim değişikliğinin insan sağlığı üzerinde doğrudan ya da dolaylı neden olduğu başlıca zorluklar olarak değerlendirilmektedir. Bu çalışmanın amacı; iklim değişikliğinin vatandaşlarda anksiyeteye neden olup olmadığını Türkiye’de yaşayan vatandaşlar üzerinden ele almaktır. Çalışmanın iki temel hipotezi bulunmaktadır. H1: Türkiye’de yaşayan vatandaşların iklim değişikliğine karşı anksiyeteleri düşüktür. H2: Demografik değişkenler, vatandaşların iklim anksiyeteleri açısından farklılaşmaktadır. Araştırmada nicel araştırma tekniklerinden anket tekniği kullanılmış ve Türkiye’de yaşayan 407 kişiden yanıtlar toplanmıştır. Elde edilen veriler SPSS 23 paket programı kullanılarak analiz edilmiştir. Analiz yöntemi olarak yüzde ve frekans dağılımı, açıklayıcı faktör analizi, Mann-Whitney U Testi ve Kruskal-Wallis Testleri kullanılmıştır. Araştırma sonucunda Türkiye’de yaşayan vatandaşların iklim anksiyetelerinin oldukça düşük olduğu görülmüş ve H1 hipotezi kabul edilmiştir. İklim değişikliği anksiyetesi skorlarının genel anlamda oldukça düşük olduğu görülmüş, çeşitli önermeler açısından demografik değişkenler arasında farklılaşma olsa da genel mahiyette anlamlı olmadığından H2 hipotezi reddedilmiştir.

Published: December 2023

This research delves into the integration of a high-touch high-tech approach for preservice English teachers who developed a hypothetical qualification-based job preparation Metaverse platform within the framework of the ADDIE model. Various generative AI tools were utilized to streamline content creation process for the Metaverse platform, with simultaneous vetting and curation of the content by preservice teachers to ensure its pedagogical relevance and suitability. This Metaverse job preparation platform offers dynamic interactive content for career exploration through MBTI, SWOT analysis, along with virtual simulations to navigate different career trajectories, create resumes, and improve interview skills in English. To validate the effectiveness of the high-touch high-tech program, a non-parametric Wilcoxon rank-sum test was performed: the average post-evaluate scores increased for most variables, with perceived interest (PE, z = -4.141, p < 0.001) and social influence (SI, z = -2.707, p = 0.006) showing statistically significant results. By focusing on the tasks that generative AI can undertake in collaboration with human teachers, this research highlights a five-stage AI-human teacher role model that combines AI capabilities with human expertise. This research offers a glimpse into a high-touch, high-tech educational paradigm, where the fusion of technology and human insight works to enhance learning outcomes.

Between Fancy and Functionality: Comparative Thermal Performance Analyses of Selected External Building Shading Elements in Tropical Building Design
Authors: Olaniyan S. A. , Adebisi I. I. , Onigbogi O. O..
Published: December 2023

Tropical region is characterized by high temperature, arising from high solar radiation. Incoming near-infrared energy emanating from excessive direct sunlight leads to increase in the indoor temperature with its attendant indoor thermal discomfort. Thus, there is the need for protection of the interior from this excessive direct heating. One of such protective approaches is the introduction of exterior shading elements to block the incoming solar energy. To achieve this in a typical tropical city of Ogbomoso, Nigeria, several forms of exterior window shading elements are adopted predominantly based on individual preferences, fancies, etc., without scientific consideration for their effectiveness. This study therefore investigated performance effectiveness of each type, with a view to identifying the most effective shading element in the study area. The study adopted the use of multiple/iterative building performance simulation tool, DesignBuilder for evaluating indoor thermal performance of a typical three-bedroom residential building, with regard to four predominantly adopted fixed external shading elements in the study area. Virtual models of five variants of the building were subjected to energy performance simulation analysis, using weather data for Ogbomoso. While the first building tagged Building I was modelled without any shading element, to serve as the control building, the remaining four tagged Building II, Building III, Building IV and Building V were modelled with overhangs, side-fins, hybrids and louvres shading system respectively. Building V recorded highest reduction (56.55%) in the indoor solar gains. This was followed in the order of Building IV (23.90%), Building II (16.00%), and Building III (7.63%). Thus, effectiveness of external louvres system as an external shading device over side-fins and overhangs in the study area could be established. This research is necessary to minimize additional active energy required to reduce the indoor thermal discomfort arising from solar gains (through reduced annual space cooling loads). This will increase building energy efficiency and reduce carbon emissions for overall clean and safe global environment

Published: December 2023

Thermal discomfort in lecture theatres can create unsatisfactory conditions for effective learning. Achieving a thermally comfortable indoor environment in any building is of great importance for all building users. However, this has become a complex task in educational buildings. This study assessed the thermal comfort parameters in 6 lecture theatres of the main campus of Ahmadu Bello University, Zaria. The study adopted both the objective and subjective approach of thermal comfort assessment. Checklist was used to characterize lecture theatres while measuring devices were used to collect data on air temperature, relative humidity, and air velocity. A total 510 questionnaire was used to collect data on users’ perception on thermal sensation. Findings from the objective assessment for morning and afternoon sessions, showed that the indoor air temperature, relative humidity, and air velocity were in the range of 27.53oC to 35.59oC, 35.29% to 55.34%, and 0.01 m/s to 1.23 m/s respectively. Findings from the subjective assessment showed the thermal sensation vote to be 28.4% and 18.6% for morning and afternoon votes respectively. Results from the inferential statistical analysis showed significant differences (p≤0.05) in the mean value of the thermal comfort parameters measured across all the theatres. The study recommended that natural ventilation should be adequately augmented with sufficient mechanical ventilation systems in the lecture theatres to enhance the thermal condition of the indoor spaces. Also, future designs of lecture theatres should comply with accepted standard for achieving optimum thermal comfort.

Introduction. Flaviviruses, possessing natural neurotropicity could be used in glioblastoma therapy using attenuated strains or as a delivery system for antitumor agents in an inactivated form.
Objective. To investigate the sensitivity of glioblastoma and pancreatic carcinoma cell lines to vaccine strains of yellow fever and tick-borne encephalitis viruses.
Materials and methods. Cell lines: glioblastoma GL-6, T98G, LN-229, pancreatic carcinoma MIA RaCa-2 and human pancreatic ductal carcinoma PANC-1. Viral strains: 17D yellow fever virus (YF), Sofjin tick-borne encephalitis virus (TBEV). Virus concentration were determined by plaque assay and quantitative PCR. Determination of cell sensitivity to viruses by MTT assay.
Results. 17D YF was effective only against pancreatic carcinoma tumor cells MIA Paca-2 and had a limited effect against PANC-1. In glioblastoma cell lines (LN229, GL6, T98G), virus had no oncolytic effect and the viral RNA concentration fell in the culture medium. Sofjin TBEV showed CPE50 against MIA Paca-2 and a very limited cytotoxic effect against PANC-1. However, it had no oncolytic effect against glioblastoma cell lines (LN229, T98G and GL6), although virus reproduction continued in these cultures. For the GL6 glioblastoma cell line, the viral RNA concentration at the level with the infection dose was determined within 13 days, despite medium replacement, while in the case of the LN229 cell line, the virus concentration increased from 1 × 109 to 1 × 1010 copies/ml.
Conclusion. Tumor behavior in organism is more complex and is determined by different microenvironmental factors and immune status. In the future, it is advisable to continue studying the antitumor oncolytic and immunomodulatory effects of viral strains 17D YF and Sofjin TBEV using in vivo models.

Introduction. Although domestic pigs and wild boars are the main reservoir of zoonotic hepatitis E virus (HEV) genotypes in temperate countries, the presence of antibodies to HEV (anti-HEV) in the indigenous population of circumpolar territories, i.e. outside the habitat of wild and domestic pigs, indicates the presence of an alternative reservoir of the virus. Reindeer (Rangifer tarandus) may be a potential reservoir for HEV in the polar regions. The purpose of the study was to determine the prevalence of anti-HEV among domestic reindeer in the Republic of Sakha (Yakutia).
Materials and methods. Sera from 497 domestic reindeer from the Oymyakon (n = 425) and Ust-Yansky districts (n = 72) of the Republic of Sakha (Yakutia) were tested for anti-HEV. A commercial ELISA kit DS-ELISA-ANTI-HEV-G (Diagnostic Systems-Stolitsa LLC, Russia) was used for detection of anti-HEV IgG, but a rabbit polyclonal antibody against deer IgG labeled with horseradish peroxidase (KPL, USA) at a dilution of 1 : 100 in phosphate-buffered saline were used instead of the human specific conjugate from the kit.
Results. The average detection rate of anti-HEV in reindeer sera was 15.5% (95% CI: 12.6–19.0%). The detection rate of anti-HEV significantly increased with age, from 3.5% (95% CI: 1.1–9.0%) in calves aged 3–6 months to 25.0% (95% CI: 1.6 –36.5%) in deer aged 2–4 years (p 0.0001). From this age group, anti-HEV detection rates reached a plateau, not differing significantly between older age groups (p 0.05). The average anti-HEV detection rate among reindeer 2 years of age and older was 19.0% (95% CI: 15.3–23.4%). There were no statistically significant differences in the frequency of anti-HEV detection between female and male reindeer, both among adult animals and among calves.
Conclusion. The observed anti-HEV detection rates among domestic reindeer in the Republic of Sakha (Yakutia) indicate that infection caused by HEV or an antigenically similar virus is common in these animals. The dynamics of antibody accumulation in the reindeer population indicates that infection apparently occurs during the first two years of life.

Desde a antiguidade, o plantio de ervas e plantas foi aliado dos seres humanos, uma vez que, além das questões alimentares e nutricionais, ele ofereceu mecanismos medicinais para a sociedade como na civilização egípcia, considerada berço da farmácia e medicina, por exemplo. Com o advento das técnicas in silico, a pesquisa de plantas medicinais e seus respectivos mecanismos terapêuticos tornaram-se mais acessíveis e elaboradas, fazendo com que os estudos na área sejam desenvolvidos com uma maior precisão e qualidade. O Brasil, por possuir uma vasta extensão territorial e abranger diferentes zonas climáticas, abriga inúmeras espécies de vegetais, contribuindo para que existam alternativas terapêuticas a partir do uso de substâncias encontradas em plantas nativas. A espécie Tabebuia avellanedade, conhecida popularmente como Ipê Roxo, é utilizada na medicina popular como antineoplásica, anti-inflamatória, analgésica, anti-malárica e anti-infecciosa. O presente estudo foi elaborado com o intuito de elucidar, a partir de ferramentas in silico, as propriedades terapêuticas dos compostos majoritários encontradas na espécie citada, de modo a esclarecer seus mecanismos difundidos na medicina popular. Foi observado que a β-lapachona, presente na casca do vegetal, inverteu efeitos tumorais em camundongos portadores do tumor de Ehrlich, reduziu a viabilidade das células de melanoma em ratos, apresentou propriedades antiangiogênicas. Além disso, o extrato seco da casca da espécie em estudo apresentou efeito antibacteriano em cepas de H. pylori, apresentando resultados semelhantes à antimicrobianos como metronidazol e azitromicina. Foi evidenciado potencial antiparasitário contra a L. amazonenses e L. infantum e propriedades analgésicas e antiinflamatorias por aumentar significativamente o limiar da dor em camundongos. Dessa forma, é possível perceber que a T. avellanedae possui grande capacidade terapêutica e, a partir de mais estudos envolvendo a espécie será possível testar suas substâncias in vitro, possivelmente in vivo, e a partir de então promover a triagem de fármacos.

Published: December 2023

The study has shown how classifiers behave when identifying and categorizing Alzheimer's disease stages. The main characteristics of various frequency bands were fed into the classifier as input. The accuracy of recognition is evaluated using machine learning classifiers. The effort aims to create a novel model that combines pre-processing, feature extraction, and classification to identify different stages of disease. The study starts with band filtering, moves on to feature extraction, which derives several bands from the EEG signals, and then employs KNN, SVM, and MLP algorithms to measure classification performance. AD detection and classification using machine learning classifiers such as KNN, SVM, and MLP is the main focus of this research. Five wavelet band characteristics are used by the built-in classifiers to categorize different disease phases. These characteristics are computed using DWT, PCA, and ICA, which aid in obtaining wavelet-related knowledge for learning. The proposed machine learning model achieves a classification accuracy of 95% overall.

Authors: Anas Nisar Syed , Jamil Tariq
Published: December 2023

This study focuses on the mechanical behavior of natural fiber-reinforced polymer composites (NFRPs), which are gaining prominence as sustainable materials due to their biodegradability and eco-friendliness. In this study, we aimed to gain a profound understanding of the mechanical behavior of selected NFRPs. Static structural analysis was conducted to simulate tensile effects, while vibrational analysis was performed to predict natural frequencies. The results indicated that all fibers exhibited minimum stress at the 67.5° angle and maximum stress at the 22.5° angle during tensile testing. Additionally, minimum deformation occurred at the 0° angle, whereas maximum deformation was observed at the 67.5° angle. Interestingly, the NFRPs exhibited similar natural frequencies for the lower modes (1st and 2nd), with negligible alterations due to fiber angles. The core aim of this study is to showcase the practicality and viability of the investigated NFRPs by employing sophisticated finite element analysis to anticipate their material behavior beforehand, allowing for a comprehensive comparison of the natural frequencies, stresses, and deformations with traditional Carbon Fiber Reinforced Polymer (CFRP) composites, thereby exploring the potential of NFRPs as feasible alternatives.

Interacción Suelo-Estructura para edificaciones con platea de cimentación por los modelos estático y dinámico
Authors: Olivera Raúl , Villarreal Genner
Published: December 2023

Las condiciones dinámicas del suelo y la flexibilidad de la cimentación, son factores que condicionan la respuesta estructural de las edificaciones, sin embargo, actualmente se considera para el diseño sismorresistente que el suelo es completamente rígido e indeformable, con nula capacidad de amortiguamiento, condición que se determina y establece mediante el empotramiento perfecto de la edificación en la base. Este criterio hipotético de empotramiento facilita el análisis y diseño de las estructuras sismorresistentes, sin embargo, se obvia un factor condicionante de importancia, pues al presentarse rigidez variable en los estratos, amortiguamiento y asentamientos diferenciales, los esfuerzos y las deformaciones en los elementos estructurales pueden variar, disminuyendo o incrementando la demanda sísmica. Con estos precedentes, en el estudio se consideraron las condiciones dinámicas del suelo, mediante los principales modelos de interacción suelo-estructura. En el estudio, se realizó la modelación de una estructura multifamiliar con los diversos coeficientes obtenidos de los modelos desarrollados por Winkler, Pasternak, Barkan & Savinov, Norma Rusa, Gazetas & Mylonakis, Pais & Kausel, en el estudio de suelos se determinó que el suelo se clasifica como flexible S3, y la zona de peligro sísmico es Z=4 correspondiente al distrito y provincia de Tumbes. Con los resultados obtenidos del modelamiento, se demostró que los esfuerzos, las deformaciones y la frecuencia de vibración de la estructura se incrementaron, en comparación con la misma estructura modelada con el criterio hipotético de restricción en la base.

Применение компьютерных технологий позволяет спрогнозировать качественные и количественные показатели оценочных параметров срезаемого слоя до стадии изготовления, что, в свою очередь, позволяет вносить изменения в геометрию инструмента, решать задачи по улучшению эффективности обработки до его изготовления. Проведено исследование на примере предложенного метода формообразования РК-профильных отверстий, суть которого заключается в применении фрезы с конструктивной радиальной подачей. С применением разработанного программного обеспечения был проведен анализ изменения кинематических углов фрезы, определены интервалы изменения передних и задних углов в процессе резания, установлено время контакта i-го зуба фрезы, сформированы выводы о неравнозначности условий нагружении зубьев фрезы при обработке и созданы предпосылки для последующего изучения износостойкости инструмента. Результаты проведенного исследования могут быть применены при проектировании металлорежущего инструмента для формообразования гранных внутренних поверхностей, в частности, при расчете значения переднего и заднего углов инструмента

one of the main tasks facing the domestic mechanical engineering, and, in particular, tool production, is the design of metal-cutting tools based on modern computer technologies using mathematical modeling of cutting processes at the development stage. The use of computer technology makes it possible to predict the qualitative and quantitative indicators of the estimated parameters of the cut layer before the manufacturing stage, which in turn makes it possible to make changes to the geometry of the tool and solve problems to improve the processing efficiency before its manufacture. In this article, a study was carried out using the example of the proposed method of shaping profile holes with equiaxed shape, the essence of which is the use of a cutter with a constructive radial feed. Using the developed software, an analysis of changes in the kinematic angles of the cutter was carried out, the intervals for changing the front and rear angles during the cutting process were determined, the contact time of the i-th cutter tooth was determined, conclusions were drawn about the unequal loading conditions of the cutter teeth during processing, and the prerequisites were created for the subsequent study of wear resistance tool. The results of the study can be used in the design of metal-cutting tools for shaping faceted internal surfaces, in particular when calculating the values of the rake and back angles of the tool

The main metallurgical aspects that must be taken into account in the production of disk blanks with a diameter of up to 300 mm by hot forging are presented using the example of a nickel high-temperature alloy of the VZh179 type. The temperatures of phase transformations in the material under study are determined using the method of differential thermal analysis. On the basis of these data, the temperature-time modes of heat treatment of disk forgings are selected. The computer simulation of the hot forging process is carried out in the QForm 3D software package.

The structure and properties of borated layers obtained on steels with different alloying elements by the method of liquid electrolysis-free boriding in a melt with the addition of yttrium oxide are studied. It is shown that the presence of an additive of yttrium oxide makes it possible to significantly increase the depth of the borated layers and reduce the microhardness of the borated layers. Elemental analysis showed the presence of yttrium content on the surface of the samples in an amount of up to 1.565 % wt. X-ray diffraction analysis revealed the presence of classical boride phases FeB, Fe2B.

Published: December 2023

This study aims to investigate the role of psychological contract breach as a predictor of employee voice behavior. For this study, data was collected from employees working in A category hotels in Srinagar, Kashmir, India. The findings offer empirical evidence supporting the hypothesis that psychological contract breach (PCB) has a negative relationship with employee voice (EV). The finding is consistent with social exchange theory, suggesting that employees reactions are influenced by the treatment they receive from their organizations. The study contributes to the current body of literature on psychological contract breach and its impact on discretionary work behaviors.

Another common type of HAIs is phlebitis. Phlebitis is a common infection associated with healthcare. Phlebitis prevention initiatives are primarily dependent on the expertise of nurses, this knowledge is directly tied to the nurses' performance of their duties and the success or failure of those duties in preventing patients from contracting phlebitis.

Objectives: The purpose of this study was to determine the correlation between nurse’s knowledge and phlebitis prevention efforts at Idaman Hospital, Banjarbaru City

Methods: A cross-sectional, correlational design was adopted for this research. Probability sampling using stratified random sampling is used for the sampling. In all, 129 nurses made up the study's sample. Data was gathered using questionnaires on basic demographics of the nurse, nursing knowledge, and phlebitis prevention efforts by nurse.

Results: The results of the study found that there is a correlation between knowledge and efforts to prevent phlebitis at Idaman Hospital, Banjarbaru City (p value=0.001; OR=3.77). Nurses who have good knowledge have the opportunity to make efforts to prevent phlebitis events optimally by 3.77 times compared to nurses who have poor knowledge.

Conclusion: The better the nurse's understanding of the incidence of phlebitis, the more effective will be the nurses' efforts to avoid phlebitis at Idaman Hospital in Banjarbaru City

DETERMINANTS OF MYOCARDIAL INFARCTION OUTCOMES IN A NON-PERCUTANEOUS CORONARY INTERVENTION HOSPITAL IN JAKARTA
Authors: Laili Talitha Syifa , Winarti Wiwin
Published: December 2023

Background: Global cardiovascular challenges persist, notably in myocardial infarction (MI). Despite studying factors such as age, sex, MI type, and comorbidities impacting survival, knowledge gaps exist, particularly in Indonesia without recent MI data, especially in non-PCI settings.
Objectives: This study seeks to bridge the knowledge gap concerning determinants of post-MI survival in hospitals without PCI facilities in Jakarta, Indonesia.
Methods: Adopting a retrospective cross-sectional design, 112 medical record patients from an Emergency Department of non-PCI hospital in Jakarta were selected via purposive sampling. A structured checklist was utilized to assess 16 variables and the primary endpoint was post-treatment status. The study employed Chi-square, Fisher's exact, and Likelihood ratio tests to analyze the relationship between demographics, risk Factors, and MI treatment access and the post-treatment status.
Results: Results highlighted that of 112 myocardial infarction (MI) patients, males constituted 70.5%, with Non-ST Elevation Myocardial Infarction as the predominant subtype (57.1%). Most participants (86.6%) were ≥45 years old. Prevalence rates included hypertension (56.3%), Diabetes Mellitus (40.2%), Congestive Heart Failure (42.0%), and prior MI (27.7%). Post-MI survival stood at 92.9%, with 7.1% mortality. The results revealed a significant correlation between cardiogenic shock and MI outcomes (p=0.000), indicating a protective advantage (OR: 0.018) for those without cardiogenic shock against MI-related mortality.
Conclusion: While cardiogenic shock has been reaffirmed as the sole predictor of post-myocardial infarction mortality in our study, it's crucial to heighten awareness of other MI determinants, including age, gender disparities, smoking status, and the dynamics of therapeutic measures. This underlines the pressing need for early identification and evidence-based management strategies.
