Aydin, Kemal; Hidiroglu, Mehtap; Kahraman, Nizamettin
Automotive industry in recent years, has gained great importance. In line with this, DP600 and DP800 dual-phase steels and the electrical resistance spot welding method were used in the study. During the experimental trials, different welding currents (6, 7, and 8 kA) were selected and all other welding parameters were kept constant. The effects of the welding parameters on microstructure, hardness, tensile-shear, and cross-tensile strength were analyzed. In the phase measurements, 27.06–29.97% martensite and 70.73–73.85% ferrite phases were found. When the hardness values in the HAZ regions were examined, it was seen that the highest hardness values were 356 ± 5 HV in the DP600 and 451 ± 5 HV in the DP800 with a current intensity of 6 kA. Consequently, it was determined that tensile-shear and cross-tensile strengths had increased in parallel with the increase in the welding current and the highest values were determined as 8 kA–15.91 kN in tensile shear and 8 kA–4.91 kN in cross-tensile strength.

Küçük Matcı, Dilek; Çömert, Resul; Avdan, Uğur
Urban areas of major cities in developing countries are expanding rapidly due to rapid population growth and industrialization. Determining the reasons for rapid urbanization and the amount of urban area that will be needed in the future is important for the planned growth of these cities. In this study, the LU/LC change of Eskisehir city center that has a rapid rate of urbanization and industrialization in Turkey between 1984 and 2020 was determined. Then, the area needed for urban and industrial areas in 2030 was investigated using the Cullullar Automata–Markov Chain (CA–MC) hybrid model simulation. Each year's LU/LC map was produced with over 80% kappa accuracies performing the pixel-based Random Forest (RF) algorithm for change analysis. In the change analysis made between 1984 and 2020, it was determined that there was a change of 117% in the urban area and 977% in the industrial area. The prediction was made for the validation of the CA–MC model from the period 2000–2010 to 2020. When compared with the 2020 LU/LC map, the model success was obtained as 0.84, 0.87, and 0.87 in the Kstandard, Klocation, and Kno Kappa metrics, respectively. By using the 2010–2020 periods in the estimation of 2030, it has been observed that the urban and industrial area will increase by 22.95%; therefore, there will be decreases in agriculture and other natural areas as in previous years.

In this study, we examine the dual expression of Valeontis’ concept of parallel p-equidistant ruled surfaces well known in Euclidean 3-space, according to the Study mapping. Furthermore, we show that the dual part of the dual angle on the unit dual sphere corresponds to the p-distance. We call these ruled surfaces we obtained “dual parallel equidistant ruled surfaces” and we briefly denote them with “DPERS”. Furthermore, we find the Blaschke vectors, the Blaschke invariants and the striction curves of these DPERS and we give the relationships between these elements. Moreover, we show the relationships between the Darboux screws, the instantaneous screw axes, the instantaneous dual Pfaff vectors and dual Steiner rotation vectors of these surfaces. Finally, we give an example, which we reinforce this article, and we explain all of these features with the figures on the example. Furthermore, we see that the corresponding dual curves on the dual unit sphere to these DPERS are such that one of them is symmetric with respect to the imaginary symmetry axis of the other.

Genemo, Musa Dima
Video processing is getting special attention from research and industries. The existence of smart surveillance cameras with high processing power has opened the for making it conceivable to design intelligent visual surveillance systems. Know a day it is very possible to assure invigilators safety during the examination period. This work aims to distinguish the suspicious activities of students during the exam for surveillance examination halls. For this, a 63 layers deep CNN model is suggested and named "L4-BranchedActionNet". The suggested CNN structure is centered on the alteration of VGG-16 with added four blanched. The developed framework is initially turned into a pre-trained framework by using the SoftMax function to train it on the CUI-EXAM dataset. The dataset for detecting suspicious activity is subsequently sent to this pre-trained algorithm for feature extraction. Feature subset optimization is applied to the deep features that have been obtained. These extracted features are first entropy coded, and then an ant colony system (ACS) is used to optimize the entropy-based coded features. The configured features are then input into a variety of classification models based on SVM and KNN. With a performance of 0.9299 in terms of accuracy, the cubic SVM gets the greatest efficiency scores. The suggested model was further tested on the CIFAR-100 dataset, and it was shown to be accurate to the tune of 0.89796. The result indicates the suggested frameworks soundness.

Mızrak, Sefa; Çam, Handan
The effects of natural and technological disasters on human, the environment, economy and social life can be prevented via scientific and technological developments. Especially, international scientific studies provide a better understanding of the nature, characteristics and effects of disasters. Therefore, a more resilient community can be built after disasters by reducing the damages of disasters at national and international level. The aim of this study was to investigate the factors affecting the disaster resilience of countries. In this study, by analyzing the data of 181 countries in 2018 and 2019, the rate of total population affected by disasters was employed as dependent variable and the factors indicating the development level of countries as independent variables. The data were analyzed with the help of ArcGIS 10.7 program using ordinary least squares regression analysis that reveals general relationships and geographical weighted regression analysis that shows local relationships across study area. In conclusion, in the general model, compulsory education duration in 2018 was the only variable that positively and significantly predicted the rate of total population affected by disasters. While neonatal mortality rate and unemployment predicted positively and significantly the rate of total population affected by disasters in 2019, urban population rate predicted negatively and significantly. The effect of all the independent variables on the rate of total population affected by disasters differed depending on time and region. The result of this study is expected to contribute to the national and international organizations responsible for disaster risk reduction efforts to prepare more effective and efficient disaster plans. In addition, the method and approach of this study may give an idea to scientists investigating on disasters.

Şimşek Demirbağ, Kübra; Demirbağ, Orkun
Purpose: Based on the job demands and resources (JD-R) model and conservation of resources (COR) theory, this paper aims to develop and test a model that examines the moderating role of daily remote work hours and the mediating role of work–family conflict on the effects of excessive workload and time pressure on life satisfaction due to mandatory remote work arrangements. Design/methodology/approach: Hierarchical regression analysis was used to analyze data from 400 professionals working in the IT sector in Turkey. Scales developed by previous researchers were used to measure excessive workload, time pressure, work–family conflict and life satisfaction. While these four variables were measured with 19 statements, daily remote work hours were determined with a single question. The collected data were validated using confirmatory factor analysis, and the hypotheses were tested using structural equation modeling. Furthermore, the reliability and validity of the data were confirmed. Finally, PROCESS was applied to examine moderated mediation. Findings: According to the analysis results obtained from the above sample data, daily remote work hours moderate the mediating role of work–family conflict in the relationships between (1) excessive workload and life satisfaction and (2) time pressure and life satisfaction. In other words, the findings show that job-related demands arising from workload, time pressure and remote work hours prevent employees from meeting their family obligations, thereby increasing work–family conflict and ultimately affecting life satisfaction. Practical implications: The study can help employers, managers, human resource professionals, policymakers and researchers increase employees' life satisfaction due to the changes in job demands experienced by employees in companies that have transitioned to remote work practices. It can provide new approaches for dealing with dissatisfaction arising from work-related conflicts in Turkey's changing environment. The results can greatly facilitate the Turkish companies' efforts to create more innovative work arrangements and make an outstanding contribution to improving employee performance in Turkey's transition to remote work practices by focusing on reducing workload, time pressure and long working hours and creating employee-centered remote work models. Originality/value: As per World Health Organization, the world will face frequent pandemic in the coming years, and thus organizations should be aware of remote work practices that will become widespread. This study provides a new perspective on the impact of employees' changing job demands on work–family conflict and life satisfaction during organizations' transition to new work arrangements in the face of the social crisis created by the COVID-19 pandemic. The study also contributes to closing the research gap between job demands, work–family conflict and life satisfaction.

Araz, Onur; Cakir, Tufan; Ozturk, Kasif Furkan
The main goal of this paper is to investigate the influence of the earthquake frequency content on the optimization of tuned mass damper (TMD) for multi-story buildings. Earthquake frequency content is divided into three groups (i.e., low, intermediate and high frequency content) according to the ratio of peak ground acceleration to the peak ground velocities. Time-domain analyses are performed to obtain the dynamic responses of 10-story and 40-story shear buildings equipped with a TMD under twelve different earthquake records. Advanced firefly algorithm is used to obtain the optimum parameters of the TMD such as the frequency ratio and the damping ratio. The optimization criterion is selected as the minimization of the maximum top story displacement of the building with TMD. The optimum parameters of TMD designed by this paper and its control performance are compared with those of other previous works available in the literature. Compared to the other methods, the optimum TMD designed by this study especially performs better in reducing the maximum top story displacements. Furthermore, it is discussed why TMD is ineffective in reducing the maximum floor accelerations of 40-story building, and then the effect of different mass ratios and objective functions in reducing the maximum responses of both buildings under critical earthquake excitation is investigated in detail. The results also show that the frequency content of earthquake ground motions has a significant effect on the optimum parameters of TMD and its control performance.

Seydi Ali Reis first mentioned the declination angle in his book titled Kitab-ı Muhit in 1554. Kitab-ı Cihannüma (1654), Füyuzat-i Mıknatisiye (1731), and Mârifetname (1757) gave the magnetic declination angle values in Anatolia. We have compiled magnetic declination data from 1500 to the present day in Anatolia and Istanbul. The plot of the magnetic declination angle was drawn for the first time using historical data between 1500 and 1947 for Istanbul. Three new magnetic declination maps for the periods of 1909–1910, 1970 and 2009 were produced for Turkey. The annual change map based on the data of 1970 and 2009 is also given for whole Turkey. The agonic line extending in NW-SE direction between Sinop and Antep divides Anatolia into two regions in 1910. The mean declination values obtained from qibla direction measurements made by the Presidency of Religious Affairs in all mosques give 3.11° E for 1970 and 4.74° E for 2009 in Turkey.

Ozturk, Kasif Furkan; Cakir, Tufan; Araz, Onur
The present study deals with evaluation of the effects of different ground motions, backfill-structure interaction (BSI) and soil-structure interaction (SSI) on dynamic response of a box culvert wing wall. In obtaining numerical results, five different earthquake records with different frequency contents, five different backfill types and four different subsoil types are taken into account. Firstly, a finite element model (FEM) and three analytical models are proposed for analysis of the wing wall-backfill system under fixed-base case, and these fixed-base models are compared with each other through both modal analysis and displacement time-history analysis under the assumption of linear-elasticity. After validating the ability of the FEM approach, by extending the fixed-base FEM to take account of elastoplastic behavior of soil and SSI, a three dimensional (3-D) model has been described, and 3-D nonlinear analyses have been carried out in time domain. The numerical results show that the seismic response of the wing walls are affected remarkably by the SSI, BSI and frequency content of the earthquake.

Sayar, Esra; Şengül, Mustafa; Ürkek, Bayram
Blueberry was added to ice cream samples produced from camel's milk at different concentrations. The physicochemical, rheological, and sensory properties, total phenolic content (TPC), and antioxidant capacity of samples were investigated. The acidity and hardness values of the samples increased, but total solids, fat, protein, pH, ash, overrun values, and complete meltdown time significantly decreased with increasing concentration of blueberry. The L* and b* values decreased, while a* and H° values increased due to the presence of natural colorants in blueberry. The viscosity and consistency coefficient values of ice cream samples decreased depending on the blueberry concentration, whereas TPC and antioxidant capacity increased. The addition of blueberry did not have any affirmative or negative effect on the sensory properties of samples except for appearance, color, and flavor scores. Consequently, blueberry could be added to the ice cream produced using camel's milk at less than a ratio of 10% to improve its nutritional properties. Novelty impact statement: Ice cream made from camel's milk with blueberry is a novel dairy product. It is a functional product due to its high antioxidant activity and total phenolic component. The addition of blueberry does not have a negative effect on the sensory properties of the ice cream. As a result, blueberry and camel's milk could be used in new ice cream formulations to produce a nutritional and functional product.

Dactylorhiza romana subsp. georgica is found in Anatolia and is traditionally used by local people both as food and to alleviate various ailments. Although various biological activities of the plant have been partially investigated, these properties have not been comprehensively revealed in the light of scientific data. In this study, it was aimed to elucidate the antioxidant, antimicrobial, enzyme inhibition (alpha amylase, alpha glucosidase, and tyrosinase) and DNA protective activity and phenolic content of the extracts obtained from orchid tubers using different extraction methods. For this, the fresh and dry tubers of the plant were extracted with ethanol at different times in an ultrasonic water bath, shaker and their combinations with each other. ABTS, DPPH, and FRAP methods were used to determine the antioxidant properties of plant tubers. In addition, the phosphomolybdate method was used to determine the total antioxidant capacity. The spectrophotometric method was preferred to reveal the enzyme inhibition activity. The antimicrobial activity of the extracts was investigated by microdilution method. In addition, the phenolic content of the plant was analysed by HPLC. The DNA protective activity of the extracts was determined by using the pUC 19 plasmid. According to the results obtained, it was revealed that each extract exhibited various biological activities. According to the HPLC results, the highest phenolic component in the extracts was determined as p-hydroxybenzoic acid. As a result, it was observed that the biological activities of orchid tubers changed according to different extraction methods. Accordingly, due to the high biological activities of orchid tubers, they have a high potential for use in the food and pharmaceutical industries.

Şenaslan, Fatih; Aydin, Murat
The ternary Zn–27Al–1Cu alloy is produced from raw materials by the gravity casting method. The produced alloy was subjected to aging after solutionizing and quenching. The effect of aging at different periods on the microstructure and damping behaviour of the alloy was investigated. The microstructural investigations revealed that the microstructure of the alloy in the as-cast state consisted of aluminium(Al)-rich α dendrites surrounded by eutectoid β phase, and zinc(Zn)-rich η phase and copper(Cu)-rich ε phase. The heat treatment eliminated the dendritic microstructure of the casting alloy and transformed it into a coarse-grained (β-matrix) stable form containing Zn-rich and Cu-rich precipitates. The microstructural changes after aging process were directly affected the mechanical properties of the alloy. The hardness and tensile strength increased with increasing ageing time up to 2.5 hours, but the percent elongation decreased. When the aging time reached 5 hours, hardness and tensile strength decreased while percent elongation increased significantly. The impact energy, namely toughness, increased in the early stage of aging, reduced sharply with increasing aging time and remained stable with a small increase in the prolonged stage of aging. The highest impact energy was attained from the aged alloy for 0.5 hours. The variation in damping energy was dependent on the changes in microstructural and mechanical properties caused by different aging periods. The prolonged aging process transformed the fracture characteristic of the as-cast alloy from relatively brittle to ductile fracture.

This study aimed to determine the grafting success and carbohydrate distributions for newly registered foxy grape varieties grafted on different American grapes and grown in humid conditions in the Black Sea Region of Turkey. In the study, ‘Rizessi’, ‘Çeliksu’, ‘Ülkemiz’, ‘Rizellim’, and ‘Rizpem’ foxy grape varieties were grafted on 140Ru, SO4, and 110R American rootstocks. The graft success, growth, and development characteristics were determined, and carbohydrate accumulations and distributions at the graft area, under the graft area (rootstock), and above the graft area (scion) of the grafted grapevines in the dormant period were also determined. The highest graft success rate was 100.00% in the combinations of ‘Rizessi’/SO4, ‘Rizellim’/SO4, ‘Rizpem’/SO4, ‘Rizellim’/110R, and ‘Rizpem’/110R. The percentage of vine saplings ranged from 86.00% (‘Rizellim’/SO4) to 27.14% (‘Rizpem’/140Ru). Regarding carbohydrate distribution, the ‘Rizessi’/140Ru, ‘Rizessi’/SO4, ‘Rizessi’/110R, ‘Çeliksu’/SO4, ‘Çeliksu’/110R, ‘Ülkemiz’/SO4, ‘Rizellim’/140Ru, ‘Rizellim’/SO4, ‘Rizpem’/SO4, and ‘Rizpem’/110R combinations showed a balanced distribution. The highest total carbohydrate accumulation (100.41 mg·L−1) was detected in the root region of the ‘Ülkemiz’/SO4 combination. On the other hand, vine sapling rate enhanced as carbohydrate accumulation increased in the grafting area. The SO4 American rootstock was found to be more successful than the others.

BACKGROUND: Understanding the effects of the COVID-19 pandemic on the perception and image of the profession are key factors in nurses' perceptions regarding their roles and their future. OBJECTIVE: The purpose of this study was to determine the effect of the COVID-19 pandemic on the perception and image of the nursing profession among nurses working in surgical units. METHODS: This cross-sectional, correlational study was conducted with 216 nurses using the random sampling method between 10 and 30 March, 2022. The study data were collected using an information form, the Perception of Nursing Professional Scale (PNPS), and the Scale for the Image of the Nursing Profession. RESULTS: The nurses' mean age was 32.53±9.16 years (min 21, max 57) and their mean professional experience was 16.44±9.80 years (min 1, max 44). The mean PNPS score was 73.12±9.46, and the mean Scale for the Image of the Nursing Profession score was 171.11±11.16. Female nurses had significantly higher positive perceptions of nursing levels than male nurses. Gender, having a history of COVID-19, marginalization during the pandemic, and perception of the nursing profession significantly affected image perceptions of nursing at multiple linear regression analysis. These variables explained 43% of the total variance. CONCLUSION: Nurses working in surgical units during the COVID-19 pandemic exhibited a good level of professionalism and image perception concerning nursing.

Karapınar Kocağ, Esra; Longhi, Simonetta
One of the reasons why people hold anti-immigration attitudes is the fear that immigrants “rob jobs” of natives and decrease wages. However, academic literature finds that this is not the case. Nevertheless, in various countries, people still tend to oppose immigration. Opposition to immigration was particularly high in Turkey in the early 2000s, where almost half of the respondents to the Turkish part of the European Social Survey reported they would prefer to allow no immigrants into Turkey. This is although immigration to Turkey is very low. Turkey is becoming an important destination country as conflicts in neighboring countries force many people to flee. Therefore, understanding the opposition to immigration in Turkey is crucial for managing age immigration flows efficiently. For this purpose, we investigate the determinants of attitudes towards immigration in Turkey using the European Social Survey and Turkish population census data. The findings of the ordered probit model reveal that Turkish people tend to hold more negative attitudes towards immigration where the regional share of immigrants is higher. The little chance of contact with immigrants in Turkey through a lower share of immigrants compared to other European countries seems to influence natives’ pro-immigrant attitudes negatively.
