Authors: Aswathi Rajakumar Raja , Kumar Kolappanpillai Pazhani , Ramakrishnan Bagavathiperumal
Published: December 2023

Heart disease is the leading cause of death worldwide. It has an impact on not only the health of patients but also the economies and expenses of the countries. Numerous machine learning and data mining approaches are being developed and explored currently in order to predict various diseases. This paper aims to address the pressing global issue of heart disease by leveraging machine learning and data mining techniques. Specifically, it focuses on utilizing a Fuzzy C means (FCM) approach for attribute segmentation, employing the Whale Optimization Algorithm (WOA) for feature selection, and utilizing Deep Convolutional Neural Networks (DCNNs) for medical diagnosis and early prediction. In this study, the initial stage involves segmenting patient records' attributes using the FCM method. Subsequently, high-ranking features are selected through the WOA algorithm. These segmented features are then input into DCNNs to construct a robust medical diagnosis system and enable early-stage prediction. The DCNNs autonomously extract crucial features without human intervention, enhancing the accuracy of disease prediction. The performance evaluation of the proposed classifier is conducted using the Python platform, with the DCNN achieving an impressive accuracy level of 90.12% during testing. This indicates the DCNN's capability to accurately predict the presence or absence of cardiac disease, showcasing its potential as an effective tool in healthcare. The integration of FCM attribute segmentation, WOA feature selection, and DCNN-based prediction holds significant practical implications. It offers healthcare professionals a valuable tool for diagnosing and predicting heart disease early, potentially saving lives.
Performance analysis of IoT networks in terrestrial environment utilizing LZW data compression technique
Authors: Sisodia Ankur , Yadav Ajay Kumar
Published: December 2023

The proliferation of Internet of Things (IoT) devices in terrestrial environments necessitates efficient data transmission and management protocols to optimize network performance. This research paper presents a comprehensive study on the implementation of IoT networks in a terrestrial setting, focusing on the integration of LZW (Lempel-Ziv-Welch) compression with three prominent IoT protocols: CoAP (Constrained Application Protocol), M2M (machine-to-machine), and MQTT (Message Queuing Telemetry Transport). We did a thorough test of these protocols using the NetSim simulator. We looked at how well they worked in terms of throughput, en-to-end delay, and routing overhead, all of which are important for loT network efficiency. The point of our study is to find out what the pros and cons of these protocols are when they are combined with LZW compression in a terrestrial loT setting. The results of our analysis reveal significant variations in the performance of CoAP, M2M, and MQTT when subjected to data compression. Throughput efficiency, which directly impacts data transmission rates, is scrutinized alongside end-to-end delay, a critical factor in ensuring timely data delivery. Additionally, we explore the implications of protocol choice on routing overhead, a crucial metric for network resource utilization. This research contributes to the ongoing efforts to optimize IoT networks in terrestrial settings, offering valuable guidance to network architects and developers seeking to strike the right balance between protocol selection and data compression for improved IoT performance.
Spectrum-Aware Transitive On-Demand Routing Protocol for Military Cognitive Radio Ad Hoc Networks
Authors: Phaswana Phetho , Velempini Mthulisi
Published: December 2023

The advancement of wireless technology is increasing the demand for scarce spectrum. Cognitive radio ad hoc networks (CRAHNs) were proposed as a solution to spectrum scarcity which is also deployed in combat. However, military cognitive radio ad-hoc networks (MCRAHNs) are subject to destruction and frequent link breakages. The challenge with MCRAHNs routing is the timing-out of packets. This paper proposes the spectrum-aware transitive multi-cast on-demand distance vector (SAT-MAODV), optimised for throughput and delay. The relay nodes are selected based on zonal data and mobility. This is achieved through handshaking and sharing of location data. The nodes are expected to store location data of nodes encountered, which is used in routing and in determining the movement of the node. The mobility of military nodes is organised and structured, which simplifies routing. The SAT-MAODV was evaluated in network simulator 2 and the results show that the scheme is effective. UsingSAT-MAODV instead of xWCETT reduced routing path and node relay delay by at least 65% and 13% respectively, and increased achievable throughput by 31%. It also improved the delivery ratio by 9% while reducing latency by 27% in comparison with MARSA.

Authors: Zuma Nompumelelo , Sibindi Ntandoyenkosi
Published: December 2023

Using the National Youth Development Agency (NYDA) as a case study, this paper considers the challenges of implementing enterprise resource planning (ERP). Data was collected from management and employees using both qualitative and quantitative research techniques. The study established challenges beyond the technical issues, these included: misalignment of the system to the organisation processes, product quality and unavailability of the system’s helpdesk, lack of top management support, and lack of pilot testing, insufficient end-user training, resistance to change management, lack of processes integration, poor  technology planning and security and risk matters. Furthermore, the management process that resonates on knowledge transfer, knowledge management, and change management poses a complex challenge in the implementation of ERP. The study  recommends the alignment of the user environment, effective change management, and knowledge strategies that are essential to drive ERP. It is also recommended to close the gap between what ERP offers and what end users want and can do.
Online Platform Privacy Policies
Authors: Mugadza Kimberley , Mwalemba Gwamaka
Published: December 2023

In January 2021, Meta (then Facebook) published an update to its WhatsApp privacy policy which included, among other things, a decision to share some user data with Facebook. This action, together with previous events like the notorious Cambridge-Analytica data breach, has sparked debates about the protection of online privacy, specifically the balance of rights and responsibilities relevant to the protection of social media user data. This qualitative study contributes to that debate by exploring the perceptions and reactions of South African WhatsApp users to these policy changes. The findings highlight the significance of platforms like WhatsApp in the daily socio-economic activities of users in developing countries. This reliance on social media for communication and access to vital information creates an imbalance of power between users and platform owners. The situationis worsened by the lack of effective regulatory frameworks that governments and institutions in developing countries can use to enforce their privacy laws, leaving users vulnerable to potential exploitation from digital platforms. This study contributes to the broader discourse on safeguarding online privacy as Western technology companies continue to gain access to data that is generated by an ever-increasing global user base.
SOLAR AND GEOMAGNETIC ACTIVITY IN 19-25 CYCLES
Authors: Sumaruk T. P. , Sumaruk P. V. , Neska A.
Published: December 2023

The paper presents the results of the analysis of changes solar and geomagnetic activity in 19−25 Wolf cycles. A forecast of the maximum geomagnetic activity cycle 25 is made.
Solar activity is presented by sunspot number RZ, geomagnetic activity is expressed by the energetic index calculated from the data of the "Lviv" and "Belsk" geomagnetic observatories. By annual averages RZ values, the 11-year window was used to obtain the solar activity minimum (around 1711, 1810, 1901, and 2009). The minimum of 2009 was one of the smallest in the observed data, and we took it as the beginning of the 24th cycle and the 100-year solar activity cycle. The maximum of the 24th cycle occurred in 2014 for RZ and in 2015 for energetic index.
Cycle 25 began in 2019 according to RZ, and in 2020 cording to energetic index. For cycles 19−25 solar activity is 1−2 years ahead of magnetic activity. The identified quasi-biennial variations over the studied period and the lag of geomagnetic activity from solar activity allow us to predict the magnitude of geomagnetic activity and its maximum in cycle 25.
According to our calculations, the maximum of geomagnetic activity will occur around 2026 and its magnitude will be 1.5−2 times higher than the maximum of the 24th cycle.
A NEW METHOD OF INVESTIGATION OF THE ORIENTATION OF GALAXIES IN CLUSTERS IN LACK OF INFORMATION ABOUT THEIR MORPHOLOGICAL TYPES
Authors: Mrzygłod B. , Godłowski W.
Published: December 2023

The problem of the formation of structures in the universe is one of the most important issues of modern extragalactic astronomy and cosmology. The tool enabling the verification of a particular formation scenario is analysis the spatial orientation of the galaxies from deprojection of their images. Obtaining correct analysis results obliges to take into account the fact that galaxies are oblate spheroids with the real axis ratio depending on the morphological type, which, however, is not given in most of the currently available astronomical data. According to the approach used in the new method of investigation, on the basis of estimated frequencies of occurrence of given morphological types, obtained using sufficiently numerous observational data, simulations are performed, which enable to recognize new angle distributions used in orientation studies. These distributions already contain information on the frequency of the appearance of galaxies of particular morphological types in clusters, allowing for more accurate results of the statistical tests carried out during the analysis. The method is an extension of results developed in Godłowski 2012 and Pajowska et al. 2019.

This work is a continuation of the study of the response of the Odesa geomagnetic anomaly to the manifestations of solar and planetary geomagnetic activity. Not far from the territory of this magnetic anomaly there is the geomagnetic observatory "Odesa" and the decameter radio telescope "URAN-4" of the RI NASU. A catalogue of magnetic storms for the period 1987-1994 and 2000-2009 was compiled for the monitoring program of high-power space radio sources at RT "URAN-4" using the database of the geomagnetic observatory "Odesa". In this paper, a comparative analysis of the features of the manifestations of geomagnetic storms in the zone of the Odesa magnetic anomaly, planetary storms and ionospheric storms in the 22nd and 23rd cycles of solar activity is carried out. The main results are as follows. The magnetic anomaly amplifies the effects of regional manifestations of planetary magnetic storms. The number of different types of magnetic storms and the dynamics of their changes in the Odesa anomaly differ significantly in the 22nd and 23rd cycles of solar activity. Comparisons have shown that the duration of magnetic storms in the Odessa anomaly is longer than the duration of planetary magnetic and ionospheric storms. According to the data of the «URAN-4» radio telescope, geomagnetic storms form various manifestations of the effects of ionospheric flickers and flux changes for space radio sources depending on the time of their observations. For the region of the Odesa geomagnetic anomaly, such comprehensive studies have not been carried out before. The conducted studies will become an important basis for understanding the influence of magnetic anomalies on the dynamics of the ionosphere during periods of solar and geomagnetic activity.

Published: December 2023

The system of ten radio telescopes VLBA (Very Large Baseline Array), with a maximum baseline of about 8,600 km, of the National Radio Astronomy Observatory of the USA (NRAO USA) carries out systematic monitoring observations of about 500 active galactic nuclei (AGN), the results are presented in the MOJAVE database. The resulting angular resolution (~0.47 arcseconds at a frequency of 15.4 GHz) is enough to separate the close surroundings of the AGN and its jet. The results of corresponding observations make it possible to compare the features of movement in the jet with the processes of activity of the AGN, as well as to study its spatial structure.
The MOJAVE database contains the spectral densities of the radio fluxes of the AGN, radio images for each epoch of observations at the frequency of 15.4 GHz, and "Separation jet" diagrams (showing the angular separation of the jet components over time). This information makes it possible to study the movement of these components. In this work, a general analysis of movement patterns of the components of the 3C 273 jet was performed. In the published papers of the MOJAVE team, a similar analysis wasn’t presented for all jet’s features.

Session-Based Time-Window Identification in Virtual Learning Environments
Authors: Maslennikova Aleksandra , Rotelli Daniela , Monreale Anna
Published: December 2023

Students organize and manage their own learning time, choosing when, what, and how to study due to the flexibility of online learning. Each person has unique learning habits that define their behaviours and distinguish them from others. To investigate the temporal behaviour of students in online learning environments, we seek to identify suitable time-windows that could be used to investigate their temporal behaviour. First, we present a novel perspective for identifying different types of sessions based on individual needs. The majority of previous works address this issue by establishing an arbitrary session timeout threshold. In this paper, we propose an algorithm for determining the optimal threshold for a given session. Second, we use data-driven methods to support investigators in determining time-windows based on the identified sessions. To this end, we developed a visual tool that assists data scientists and researchers to determine the optimal settings for session identification and locating suitable time-windows.
How Does Inclusion Impact Employees in Organisations? Literature Review
Authors: Dudek Alicja
Published: December 2023

Purpose: The purpose of this systematic literature review is to review the current state of research on the impact of inclusion in organisations on employees.
Methods and materials used: The presented analysis of the empirical literature on the impact of inclusion was undertaken utilising two databases: Scopus and the Web of Science. In addition, a manual search of prominent journals within the ‘Organisational Behaviour and Human Resource Management’ category was performed. A total of 166 articles resulted from the conducted literature search, with 11 studies meeting the inclusion criteria.
Main findings: Inclusion is a concept inspiring empirical research aiming to identify the positive impact of inclusiveness on employees in organisations. Empirical research indicates that inclusiveness has a positive impact on employees by stimulating their creativity, reducing turnover, increasing organisational commitment and citizenship behaviour, and improving employee well‑being and self- ‑esteem. The area that has received the most attention is inclusive leadership, but inclusive practices and, more broadly, inclusive organisations are also explored.
Principal conclusion: The research focuses on the positive impact of inclusion on an organisation’s employees: their attitude, behaviour and intentions. The review has revealed that the dominant stream of research is inclusive leadership. What is lacking, however, is empirical research on how inclusion affects other stakeholders, so future studies should explore that.
The Potential of Personality Tests in the Candidate Selection Process: A Critical Analysis Using Argument Mapping
Authors: Zawadzki Kamil , Wojdyło Monika
Published: December 2023

Psychological testing – including personality tests – is one of the methods used by contemporary organisations for selection of candidates. This article provides a systematic analysis of arguments concerning the validity of this selection method using the argument mapping technique. The study highlights doubts regarding the validity of assessing a candidate’s potential on the basis of such tests due to the significant potential for result manipulation by the candidate. The primary conclusion drawn from this analysis is that personality tests should only be used as a complementary instrument alongside other selection techniques. Test‑based assessment methods should be used optionally, while adhering to appropriate standards for conducting such tests. The study also suggests a shift away from self‑report tests and entrusting their execution and interpretation to individuals with relevant qualifications.

Authors: Tummala Srinivas , Banothu Anilkumar , Kumar B. , Lakshman M. , Ambica G. , Ravikumar Y.
Published: December 2023

Background: Methotrexate (MTX) is an anticancer drug and its clinical efficacy is limited to the toxicity associated with the liver. In this study, we examine the potential role of aqueous leaf extracts of Bacopa monnieri to counter methotrexate-induced hepatotoxicity. Methods: This study was undertaken by considering 36 numbers. Wistar male rats were randomly segregated into six groups, with six rats per group. Groups 1 and 2 were kept as normal controls and methotrexate was treated on the 9th day. While groups 3 and 4 received an aqueous extract of the leaf of B. monnieri at two varied doses of 150 and 300 mg/kg, respectively, as a treatment, Whereas groups 5 and 6 kept B. monnieri perse and the standard hepatoprotective drug silymarin @ 200 mg/kg and experiment was conducted for 14 days period. After the experimental procedure, AST, ALT, TNF-á and IL-10 were measured and histopathology of the liver was done. Result: The present study revealed significant alterations in AST, ALT, TNF-alfa and IL-10 in methotrexate-treated rats (group 2) when compared to group 1 and treatment groups 4 and 5 revealed significant improvement and these results were validated through imaging in the histopathology of the liver. We conclude that Bacopa monnieri can efficiently reduce methotrexate-induced liver inflammation and can be used in the management of hepatotoxicity in the liver.

Background: Naturally occurring iodide iodine exhibits complex soil behavior. Even though higher plants don’t consider iodine a vitamin, living things need it. Iodine is part of the thyroid hormone, which is vital to human health and metabolism. Potassium is the most effective cation for tomato plants and has a crucial role in improving several post-harvest quality characteristics in tomato fruits as well as in almost all vegetables. Methods: In the present work, we assessed the growth, yield and quality (Ascorbic acid, Titrable acidity and soluble solids) of tomatoesfrom different sources of chitosan and potassium iodate alone and combinations. The field experiment was carried out in the Thondamuthur block of Viraliyur village in the Coimbatore district of Tamil Nadu in 2022. The experiments were performed in randomized block design with three replications in palaviduthi soil series using hybrid tomato “Shivam”. Result: The chitosan iodate complex and foliar application combination enhanced the growth, yield and quality of tomato. Potassium iodate alone applied to soil and foliar, improved fruit quality but did not prevent acid loss during ripening. Chitosan reduces respiration and oxygen permeability to preserve losses. Thus, potassium iodate chitosan complex was favoured for boosting plant growth, fruit yield and quality.

Authors: Tirchi N. , Holgado R. , Karahacane T. , Mokabli A.
Published: December 2023

Investigation on plant-parasitic nematodes (PPN) in Algeria date back to the late 19th century. Important research has been performed since this period until currently generating significant information. The aim of this literature assembling is making available an outline of the current situation of plant nematology in the country. This review is based on the available information existing at universities’ libraries and research articles obtained by visiting web pages and Google Scholar. All pertinent information was collected from 2018 until today. This review article shows three periods for Algerian agricultural nematology: First period includes the years of French colonialism and two decades after independence. Publications on PPN started in the late 19th and early 20th centuries by French and Italian researchers, working in Algeria. The second period (1980-end 1990s) was characterized by the emergence of Algerian researchers. They successively became central academics having the responsibility to educate graduate students. Their research topics were studies on geographical distribution and evaluation of damage degrees of some PPN. The third period (2000 until today) is characterized by the progression in nematological research in the country; research topics expanded and became more diverse. Collaboration between universities, National Institute of Agronomic Research and National Institute of Plant Protection are the organisations contributing to the development of nematology. Till date, a total of 38 genera and 43 species of PPN including economically important nematodes were documented in Algeria.

En Colombia el conocimiento etnomicológico es cobijado por las comunidades campesinas e indígenas y se estima que 70 especies son consumidas. En este trabajo se estimó la importancia cultural de los hongos silvestres comestibles (EMCSI) en cuatro municipios de Boyacá (San Mateo, Miraflores, Togüí y Pauna). Los hongos se utilizan como alimento y raramente como medicina; de un total de 20 especies reportadas, se evidencia el uso local de 12 especies. Los hongos con mayor EMCSI fueron Crepidotus palmarum, Auricularia fuscosuccinea, Ramaria spp., Agaricus aff. trinitatensis y Pleurotus sp.1. Las variables culturales que describen el conocimiento tradicional incluyen ocho de las consideradas en el EMCSI, a excepción del índice económico. Este trabajo construye una relación de conocimiento de forma dinámica; la participación de la comunidad involucra un intercambio de saberes que debe verse reflejado en la conservación de los bosques, la apropiación de este servicio ecosistémico de provisión y el fortalecimiento del interés por el conocimiento tradicional en los jóvenes y niños.

Published: December 2023

Objetivo: Escrito a partir de resultados parciales de una investigación en la línea de saberes, conocimientos y prácticas en la formación de profesores de matemáticas, este artículo busca develar las realidades ocurridas en las aulas de clase de matemática escolar a causa de la pandemia generada por el virus SARS-CoV-2. Su principal interés es el análisis del significado vital de los fenómenos y la comprensión del sentido e importancia que éstos tienen en el contexto de práctica.
Método: Es una investigación cualitativa de tipo fenomenológico hermenéutico desde la perspectiva práctica de la investigación educativa de Van Manen, es decir, de la experiencia vivida.
Estrategia/recolección de información: Revisión documental, legislaciones, informes y entrevistas en profundidad.
Originalidad/aporte: La implementación de elementos propios de la investigación colaborativa y del análisis narrativo permitieron detectar las "huellas del contexto".
Conclusiones: Las voces de los profesores del área dan cuenta de los retos que tuvieron que afrontar diferentes comunidades educativas durante el primer año de esta contingencia sanitaria, mostrando las realidades en el acontecer del proceso de enseñanza-aprendizaje de las matemáticas. Además, los análisis realizados a los relatos de los docentes mostraron los tropiezos que tuvieron los maestros al creer que la realidad educativa allí emergente se trataría simplemente de una implementación de recursos tecnológicos existentes, sin tener presente las implicaciones sociales, morales, culturales y éticas que ello acarrearía; evidenciaron los momentos de incertidumbre, tensión y preocupación suscitados por la crisis sanitaria y, finalmente, muestran la capacidad de resiliencia de los principales protagonistas del acto educativo.

Published: December 2023

Mediterranean Diet has been widely studied and its nutritional, healthy, and sustainable benefits have been recognized. However, in the last decades, globalization has brought about major changes in the developed world and a progressive deviation from the main Mediterranean patterns. Fresh food and traditional recipes continue to be valued and their beneficial effects on health are scientifically proven. Despite this, they have been largely replaced by fast and less nutritious food is it possible to perform alternatives and procedures that help us to mitigate some deviations from the Mediterranean Diet, contributing to a more right, sustainable, and nutritious food system in a globalized world? This communication reinforces the idea that food technology and scientific advances must be properly applied to meet the challenges faced by Mediterranean countries.

Authors: Kruppa Ifj József 
Published: December 2023

Between 2017 and 2020, the yields and green yields of different triticale varieties and the most important nutritional parameters of triticale silage were investigated in Szarvas. The plots were sown in 4 replicates in autumn each year in a block system experiment and each plot received the same agro-technique. The earliest date of the 1st sampling in each treatment was timed to the optimal growth stage for triticale (the ear in boot was 6 cm) followed by three additional sampling. Cut 2 to 4 took place nearly every 7 days. Among the triticale varieties (genotypes) tested in the experiment, Hungaro, Dimenzio, GK Szemes and GK Maros. Between 2017 and 2020, the grain yield averages of the varieties ranged from 4.39 to 5.22 t/ha. From the first sampling date, the varieties were able to produce an average green yield of 16.6 to 26.3 t/ha with a dry matter content of 30%. At the second sampling date, the most dynamic increase was green yield 31.2 t/ha and 30.1 t/ha. By the third harvest date, the best yields were around 28.1-34.4 t/ha. At the fourth sampling time, the average yield increase of the varieties was dynamic and ranged from 26.4 to 41.5 t/ha. At the first sampling, the best fibre digestibility (NDFd48) was measured to be 67.4-73.2 %, which steadily decreased at subsequent samplings. At the fourth sampling, the worst fibre digestibility was measured to be 52.4-60.1 %, which represented a significant decrease at all sampling times.

Published: December 2023

Standards aim to limit the transmission of the infectious disease rough drinking water. To determine that the drinking water is safe and comply with the standards, information about the changes of the physicochemical parameters that occur during distribution was assessed in Souk Ahras city/Algeria. For this purpose, several samples from distribution network were taken at the consumer’s tap during the spring and summer period of 2017/2018. The obtained values of each parameter of the 14 original physicochemical were compared with the standard values set by Algeria standards. The results showed that concentration levels of chlorine free, temperature, magnesium, turbidity, nitrate, phosphate, calcium exceeded the limits of Algeria standards in certain districts, while, pH, conductivity, sulfate, dissolved oxygen, permanganate index, ammonium and nitrite were well within the limits. Signs of the presence of harmful germs and probably malfunctions in part of the equipment of the treatment processing and distribution facilities were detected.

Elastic Buckling Loads of Cold-Formed Steel Channel Sections with Perforations
Authors: Hieu Pham Ngoc
Published: December 2023

Cold-formed perforated steel sections have been commonly applied to meet the demands for technical installations, leading to the reduction of capacities of these such sections. The capacities of these sectional types have been considered in the American Specification AISI S100-16 using the Direct Strength Method (DSM). This method known as the innovative method for the design of cold-formed steel sections allows predicting the sectional capacities of perforated sections based on elastic bucking loads. Elastic buckling analyses are compulsory for the application of the DSM in the design. The determination of elastic buckling loads of perforated sections is cumbersome with the usage of current buckling analysis software programs. The paper, therefore, presents a simple method for the determination of elastic buckling loads of cold-formed perforated channel sections, especially the paper is aimed to introduce a module software program used for elastic buckling analyses of these such channel sections based on this simple method. This program is convenient for buckling analysis, and it becomes a key program for the application of DSM in the design of cold-formed perforated steel channel sections. This software program is subsequently utilized to investigate the effects of web hole dimensions on the elastic buckling loads of cold-formed steel channel sections with perforations under compression or bending. The investigated results provide fundamental understandings of the buckling behaviors of perforated channel sections due to the effects of the web holes.
A Systematic Investigation of Historical Churches in Michigan, USA
Authors: Korkmaz Kasim 
Published: December 2023

Michigan is very rich with an abundance of historical churches listed in the National Register of Historic Places including the second oldest Catholic parish in the nation. These historical churches reflect the city’s multicultural nature with their alluring architecture and offer a crucial socio-cultural involvement in extreme events as broadly observed during the pandemic period. On the other hand, Michigan is also prone to disasters such as hurricanes, tornadoes, and fires. The last flood in May 2020 resulted in dam failures and caused severe damage in Midland, Michigan. Therefore, preservation planning is urgently needed to be prepared for such extreme events including climate-related flooding. The research work investigates the historical churches in Michigan and their structural resistance to a possible natural disaster. In the research, a rapid visual inspection approach and FEMA methodology were used in combination to ensure the safety of historical churches for disaster preparedness. A structural investigation procedure was carried out for eighteen historical churches in Michigan to understand the current structural status of the historical churches. The churches were selected based on their historical characteristics. Selected churches are also the famous ones in Michigan. As a result of the carried investigation process, structural capacities, structural responses, damage risks, and hazard risks of the historical churches were defined. Structural capacities were defined with the target to increase resilience for the recovery, rebuild, and preparation for possible future disasters.
