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.

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.

Bozkir, Buğra; Acet, Tuba; Özcan, Kadriye
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.

Karabulut, Besim; Çelik, Hüseyin
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.

Sayilan, Aylin Aydin; Kulakac, Nursen
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.

In this study, the effect of green tea powder (GTP) in ice cream production on the ice cream properties and viability of probiotic bacteria [Bifidobacterium animalis ssp. lactis (Bifidobacterium BB-12) (P)] was investigated. Four ice cream groups (Control, C: without GTP and P; Probiotic Control (PC): with P; P+1% GTP; P+3% GTP samples) were produced. Bifidobacterium BB-12 (P) was added at 108 cfu/mL. pH, overrun, color, first dripping time, complete melting time and sensory properties were carried out on the second day. P was counted at 2, 15, 30, 45, 60, 75 and 90 days of storage. Bifidobacterium BB-12 number of PC was 6.54 log cfu/g at the 90th day. Bifidobacterium BB-12 number of PC was 7.10 log cfu/g, P+1% GTP sample was 6.48 log cfu/g and P+3% GTP sample was 5.84 log cfu/g at the 75th day. Bifidobacterium BB-12 number of PC was 7.24 log cfu/g, P+1% GTP sample was 6.59 log cfu/g and P+3% GTP sample was 6.69 at the 60th day. Sensory properties and probiotic counts showed that P+1% GTP sample could be accepted as a probiotic ice cream until day 75. Hence, GTP could be successfully used as a functional ingredient in the production of probiotic ice cream.

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.

Eroğlu, Alperen; Onur, Ertan
Unmanned aerial vehicles have been widely used in many areas of life. They communicate with each other or infrastructure to provide ubiquitous coverage or assist cellular and sensor networks. They construct flying ad hoc networks. One of the most significant problems in such networks is communication among them over a shared medium. Using random channel access techniques is a useful solution. Another important problem is that the variations in the density of these networks impact the quality of service and introduce many challenges. This paper presents a novel density-aware technique for flying ad hoc networks. We propose Density-aware Slotted ALOHA Protocol that utilizes slotted ALOHA with a dynamic random access probability determined using network density in a distributed fashion. Compared to the literature, this paper concentrates on proposing a three-dimensional, easily traceable model and stabilize the channel utilization performance of slotted ALOHA with an optimized channel access probability to its maximum theoretical level, 1/e, where e is the Euler’s number. Monte-Carlo simulation results validate the proposed approach leveraging aggregate interference density estimator under the simple path-loss model. We compare our protocol with two existing protocols, which are Slotted ALOHA and Stabilized Slotted ALOHA. Comparison results show that the proposed protocol has 36.78% channel utilization performance; on the other hand, the other protocols have 24.74% and 30.32% channel utilization performances, respectively. Considering the stable results and accuracy, this model is practicable in highly dynamic networks even if the network is sparse or dense under higher mobility and reasonable non-uniform deployments.

This study responds to a polemic on Indonesia’s formalization of Islamic law, which is inseparable from the dynamics of political authority and the internal views of Muslims. It seeks to describe, explore, construct, and analyze the Indonesianization of Islamic law, as proposed by Kamsi, an Islamic law professor at Sunan Kalijaga State Islamic University of Yogyakarta, as one of the efforts to make Islamic law become the national law. The Indonesianization of Islamic law, namely by legislating or codifying Islamic law through the state system so that it is enforceable in Indonesia. This study is conceptual research using a legal philosophy approach to comprehend an Islamic legal thought from a sharia scholar using the content analysis method. The results of this study show that the concept of Indonesianisation of Islamic Law uses a modern knowledge system as the paradigm. This effort seeks to nationally legalize Islamic law through Indonesian legal instruments that can give birth to inclusiveness and tolerance coupled with pluralism with differentiation in unification. Its theoretical implication emphasizes a need for epistemological and axiological adjustments to realize the concept of Indonesianization of Islamic law. The idea should also apply nationally within the framework of Pancasila (the Indonesian state’s ideology) as a democratic country.

Akyüz, Ahmet Mutlu; Durmuş, İbrahim
The environment of uncertainty created by the COVID-19 pandemic period has caused difficulties especially for healthcare professionals in their work activities. The purpose of this research is to find out which variables might affect the commitment of healthcare professionals to their works during this COVID-19 period. Based on the data announced by the Ministry of Health during the pandemic in the first quarter of 2021, it was decided to conduct a research on doctors, nurses, caregivers, and medical secretaries working in hospitals in the cities of the Eastern Black Sea Region of Turkey which generally show high risk. In the developed research model, satisfactory conditions (SC), emotional commitment to change (ECC), and psychological ownership (PO) as variables that may directly or indirectly affect the commitment of healthcare professionals to their works (CW) were used. The Smart PLS program was used in the analysis of the research model and hypothesis. It was seen that the ECC of healthcare professionals has a positive and significant (.694; p <.000) effect on SC. It was understood that the PO of healthcare professionals has positive and significant effects on their CW (.394; p <.000). It was also observed that the presence of SC has positive and significant effects on the PO of the healthcare professionals in the current situation (.796; p <.000). It was observed that only the effect of ECC of healthcare professionals on their CW is insignificant (.097; p >.086). Looking at the indirect (intermediary) effects obtained as a result of the research, it was seen that all of the hypotheses consist of positive coefficients. This situation reveals that the mediating variables have complementary effects on the obtained results.

Popescu, Cristina Raluca Gh.; Karapınar Kocağ, Esra
To begin with, Sustainable Development Goals are of tremendous importance in all areas, being seen as vital aims in all domains, which makes them indispensable when it comes to addressing the particularities of the labour market these days. Subsequently, human resources occupy a distinctive and unique position when referring to the implications derived from targeting Sustainable Development Goals, especially in the context represented by the period specific to the COVID-19 pandemic and the international events that followed immediately after that. This study investigates the work motivation of individuals, and whether they would be willing to work more hours if they are paid. Motivation and attitudes towards working more hours might be affected by several factors, and they are important contributors to business performance. Not only business performance is to be affected, but this is also a part of Sustainable Development Goals where labour market conditions and productivity concerns are addressed, along with several other factors. Using the Quarterly Labour Force Survey from 2017 to 2022 that is conducted by Statistics South Africa, this study attempts to shed light on individual preferences for working more hours in the case of South Africa. Considering the dichotomous dependent variable, a binary response model is utilised to explore the determinants of such behaviour. Findings of the probit model reveal that socio-demographic factors such as gender, marital status, education level, and work experience are important indicators to explain this preference. More precisely, being female increases the likelihood of willingness to work more hours if paid by 1.1 percentage points, and being never married increases that probability by 2.7 percentage points. Within education categories, the highest coefficient in magnitude, having tertiary education decreases the probability of willingness to work more hours by 8.2 percentage points. As an important labour market indicator, one more year to commence working increases the probability of willingness to work more hours by 0.4 percentage points.

Araz, Onur
The three-element tuned mass damper (T-TMD) is an effective passive control device for single-degree of freedom structures due to harmonic external force. Unlike previous studies, this study aims at proposing a methodology for optimization of T-TMD positioned at the top floor of multi-degree of freedom structures under seismic loads. The equations of motion for a multi-story building controlled by a T-TMD are derived, and the T-TMD is then optimized using an advanced firefly algorithm (AFA) in the frequency domain. The aim of the optimization is to minimize the amplitude of the acceleration transfer function of the top floor of the building. The proposed methodology is implemented in two different shear buildings, and the optimum parameters are then verified by using benchmark earthquakes with different frequency components. The comparisons with the available works illustrate the availability of the AFA. The effect of the mass ratio on the optimum parameters of the T-TMD is also discussed in detail. Numerical results show that the use of the optimum T-TMD is an effective strategy to minimize the maximum structural responses of the multi-story buildings under seismic excitations. In particular, the optimum T-TMD is very effective when the maximum story responses (i.e., displacement and acceleration) occur at the top floor of the building.
