    Saw-YOLOv5: Scale-Aware YOLOv5 for Object Detection in Aerial Images

    Doruk, Abdullah Enes; Algul, Mucteba; Akyurek, Feyzullah; Alpaydm, Osman Kursat; Uslu, Fatmatulzehra

    The detection of objects in aerial images is impor-tant for many real world problems related to military defense, transportation, and etc. However, this is a challenging task as a result of the presence of various scales of objects in the same image, the large variety of contexts across aerial images, various brightness levels due to image acquisition at different times of the day and so on. To address these challenges, this paper introduces Saw-YOLOv5 for object detection in aerial images. Saw-YOLOv5 is a deep network based on YOLOv5, which was proposed for object detection in natural images. Saw-YOLOv5 extends YOLOv5 with the addition of several attention modules in its design. The results of our experiments, conducted on the aerial dataset delivered by the Turkey Technology Team for the Artificial Intelligence in Transportation Competition, showed that Saw-YOLOv5 outperforms previous methods, particularly for pedestrian detection, by yielding a mean mAP of 80.23% over all objects.

    Chemical Content of Volatile Oil of Primula veris subsp. columnae, Obtaining the Methanol Extracts and their Biological Activities

    Karapınar, Çağrı; Öz, Mehmet

    The proportions and constituents of the essential oils of flowers and leaves of Primula veris subsp. columnae were determined, and the antioxidant and the antimicrobial (antibacterial and antifungal) properties of their methanol extracts were investigated. Percentage ratios and main components of the Primula veris subsp. columnae plant, which grows naturally, were detected by extracting flower and leaf volatile oils. The components of the volatile oil were identified with Gas Chromatography Mass Detector-Flame Ionization Detector (GC-MS/FID). A total of 62 compounds were identified in flower volatile oil, and methyl 4methoxysalicylate (37.1%) was determined as the main compound. While defining the structure of 50 compounds in leaf essential oil, linoleic acid (40.1%) was established as the main compound. As the result of the extraction of flowers and leaves with methanol, the extractive substance was obtained as 34.5% in flowers and as 28.8% in leaves. Methanol extraction and the antioxidant properties of the Primula veris subsp. columnae plant were quite high. In the antifungal and antibacterial activity test conducted on the volatile oils and methanol extracts of flowers and leaves of the Primula veris subsp. columnae species, only flower volatile oil showed weak inhibition properties.

    Mobile care app development process: using the ADDIE model to manage symptoms after breast cancer surgery (step 1)

    Aydin, Aydanur; Gürsoy, Ayla; Karal, Hasan

    The use of mobile applications is widespread in patient monitoring or education today. This study aims to describe the design and development process of a mobile app that supports patient self-care after breast cancer surgery. We used the ADDIE model to develop and test the mobile app. ADDIE (Analysis, Design, Development, Implementation, Evaluation) is a systematic approach based on a standard instructional design model for creating training materials. The model consists of five phases, each with its own set of steps. Once the steps within each phase are completed, the model progresses to the next phase, ultimately resulting in a “usable” product. Different team collaborations were established within each phase, and support was obtained from multiple experts during the design process. Thanks to this model, the information that patients need was transformed into a technological product. This article, which explains the stages of the product design process for mobile applications, provides information that may be helpful to researchers working on similar products.

    Hydrocarbon migration and structural reservoir traps in the Western Black Sea Basin: evidence from satellite-derived gravity tensor data

    Maden, Nafiz; Doğru, Fikret

    The Black Sea, situated between Türkiye, Bulgaria, Romania, Ukraine, and Russia, is tectonically separated into two different sub-basins: Eastern and Western Black Sea. These two sub-basins have been a target of interest for oil and gas exploration for several decades. Although the participation of the Black Sea Basin in the global oil market is very small compared to the Caspian Sea, this basin is considered a potential hydrocarbon deposit since both areas have similar characteristics in terms of source rock. In this study, satellite-derived Bouguer and free-air gravity data were interpreted to disclose the prospective hydrocarbon reservoirs and gas hydrate deposits within the Western Black Sea Basin. The locations of the maxima identified in the I2 invariants map were assessed as five substantial hydrocarbon prospective zones three of which are in the Turkish Exclusive Economic Zone. Numerous oil and gas seeps are evidence of lateral and vertical hydrocarbon migration from the source rock through major faults in the WBSB where the maximum I2 anomalies are observed.

    Hydrodynamic performance evaluation of screening on the physical unit operations in wastewater treatment based on experimentally validated CFD computations

    Şahin, Nagehan; Şibil, Rahim

    This paper introduces an evaluation of the hydrodynamic performance of the flow in the screens used on the physical unit operations in a selected full-scale wastewater treatment plant (WWTP) based on Computational Fluid Dynamics (CFD) simulations. The numerical study was carried out with the ANSYS Fluent, CFD software by using the three-dimensional (3 D), steady, incompressible flow based on the Reynolds-Average Navier-Stokes equations with three different turbulence modeling. The hydrodynamic behavior of the screening facility, combined with head pond-upstream channel-bar screens was evaluated under different conditions of the mass flow rate and velocity fields. Also, the numerical study was validated against the experimental study, which implemented in-situ measurements by Acoustic Doppler Velocimeter (ADV), and consistent results were obtained between the numerical and experimental study. Interestingly, while the Realizable (real) k-ε turbulence model with the relative error of 9.31% gave the best predicting results in the head pond, the renormalization group (RNG) k-ɛ turbulence model with the relative error of 9.05% gave the best predicting results in the upstream channel and through bar screens. As a result of the experimental measurements and CFD analyses carried out in the full-scale WWTP, the function of the screening facility was found to be incomplete. Moreover, a hydraulically improved new geometry was presented to operate the existing WWTP efficiently.

    Microwave decontamination processing of tahini and process design considerations using a computational approach

    Topcam, Huseyin; Coskun, Eda; Son, Ezgi; Kutuk, Dilay; Aytac, S. Aykut; Mert, Behic; Ozturk, Samet; Erdogdu, Ferruh

    Tahini, as a low moisture food product, is linked to several outbreaks of Salmonella recently even though a high temperature roasting (of sesame seeds) through its production is involved. Therefore, a final decontamination approach might be required for safety. Considering its higher oil content and lower thermophysical properties, conventional approaches are not easy to apply while preserving the quality attributes. Therefore, microwave heating was used for decontamination purpose. For this purpose, a computational mathematical model was developed first to determine the temperature distribution of tahini during microwave heating, and microbial inactivation studies for Salmonella enteritidis (ATCC 13076) were carried out. Changes in color and peroxide values were evaluated, and the experimentally validated model was further used to design an industrial process to achieve a 5-log cycle reduction as an efficient decontamination processing. The target temperature over 80 °C within the sample was demonstrated to achieve such a process, and industrial scale process conditions were presented for 262 kg/h process capacity.

    The effect of transurethral resection of the prostate on sexual life quality in patient spouses

    Aydin Sayilan, Aylin; Kulakac, Nursen

    The purpose of this study was to determine the effect of transurethral resection of the prostate (TURP) surgery on quality of sexual life in patients' spouses. A pre/post-operative test, quasi-experimental design with no control group was employed. The research was conducted in the urology clinics of two hospitals in the west of Turkey between 30 June and 30 September 2022. It was completed with 172 patient spouses recruited using non-probability sampling. The study data were collected using an individual information form and the Sexual Quality of Life-Female questionnaire. The preoperative test applied prior to surgery was administered by the face-to-face interview method, while the postoperative test was completed by telephone interviews 8 weeks after the initial data collection. The mean age of the individuals undergoing TURP surgery in this study was 62.69 ± 7.98 years (min 40, max 77), and the mean age of the spouses was 57.91 ± 7.46 (min 39, max 73). Sexual Quality of Life-Female scores after surgery were significantly higher than the pre-surgical values (p < 0.001). A significant difference in sex life quality was determined in terms of age, education, employment status, presence of chronic disease, number of children, and ‘love marriages’ (p < 0.05). The sexual life quality of the spouses of patients exposed to TURP surgery increased significantly 8 weeks after the procedure. The quality of sex life was higher among individuals with higher education levels, working individuals, and those who ‘married for love’, but decreased in line with age and number of children.

    Determining the factors affecting the disaster resilience of countries by geographical weighted regression

    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.

    Who said there is no place like home? Extending the link between quantitative job demands and life satisfaction: a moderated mediation model

    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.

    Effect of earthquake frequency content on seismic-induced vibration control of structures equipped with tuned mass damper

    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.

    Evaluation of Cherts in Gumushane Province in Terms of Alkali Silica Reaction

    Demir Şahin, Demet

    Alkali–silica reaction (ASR) occurs when alkali oxides coming from the cement composition in concrete come together with reactive silica and moisture coming from the aggregate. Additional maintenance and repair costs caused by the development of ASR in concrete cause the cost to increase. However, thanks to the measures taken against ASR in the early period, it contributes to the creation of sustainable and durable concrete structures. The article investigated the usability of cherts with eight different chemical compositions as aggregates in ready-mixed concrete plants in Gümüşhane. Cherts have been investigated for alkaline reactivity and are intended to be used largely as a source for concrete plants. ASR length changes of the samples prepared according to ASTM C1260 standard were determined after 3, 7, 14, and 28 days of the curing period. Microstructural examination, ultrasonic P-wave velocity, and bending and compressive strength experiments supporting ASR were carried out. The obtained test results were compared between the reference (limestone) sample and each other, as well as with the values specified in the standards. The compressive and bending strength values of the samples increase depending on their ASR. It was observed that the crack structures and types increased depending on the increase in the crack values.

    Sahin, Ali Kivanc; Cavdar, Bora; Dogan, Ramazan Ozgur; Ayas, Selen; Ozgenc, Busra; Ayas, Mustafa Sinasi

    To reduce potential threats to public health and economic losses, water distribution systems, which are critical parts of industrial control systems, require accurate and effective anomaly detection. The successful incorporation of machine learning models into anomaly detection procedures has been made possible by recent developments in computer science. In this research, a hybrid CNN-LSTM framework for anomaly detection in water distribution systems is presented using Python programming language in the JupyterLab environment. The performance of the proposed CNN-LSTM network model is carefully evaluated on the publicly available WADI dataset, which contains several types of attacks for a water distribution testbed, using a statistical window-based anomaly detection approach. The experimental results show acceptable precision, recall and F1 scores of 0.8619, 0.7041, and 0.775, respectively, demonstrating the efficiency of the framework in detecting anomalies in the water distribution system.

    Effect of individual characteristics, risk perception, self-efficacy and social support on willingness to relocate due to floods and landslides

    Mızrak, Sefa; Turan, Melikşah

    People may have to leave their home, environment, region and country because of disasters or disaster risks. Effective and efficient disaster risk reduction activities involving the community can reduce disaster risks and enable people to reside more safely and peacefully in their environment. The objective of this study was to investigate whether individual characteristics, risk perception, self-efficacy and perceived social support were correlated with the willingness to relocate due to floods and landslides. The data were collected from 947 people residing in Gümüşhane Province (Türkiye) using a survey. In the study, a total of ten models were tested with the help of ordinal logistic regression analysis. Consequently, the participants' willingness to relocate due to landslides was determined to be higher than the willingness to relocate due to floods. University students and people with chronic diseases and flood and landslide experiences had a greater willingness to relocate. Residence duration and informal social support were negatively correlated with relocation willingness. Those who believed that they could protect themselves in the event of a flood and landslide were more likely to relocate. Among risk perceptions, probability increased relocation willingness mostly due to floods, while fear increased relocation willingness mostly due to landslides. This study attempted to provide policy makers and scientists insight into disaster risk reduction and disaster risk communication related to relocation.

    Determination of shear behavior of magneto-rheological elastomers under harmonic loading

    Mazlum, Ugur; Celik, Ilhan

    Magneto-rheological (MR) materials can respond reversibly and quickly under the effect of an external magnetic field. MR materials contain micron-sized iron particles. These iron particles are typically dispersed in an elastomer or a liquid. These materials due to their properties constitute a kind of smart material in terms of engineering material. Such materials are used as isolators in various engineering applications, structures, and sound control subsystems. This study aimed to determine the mechanical properties for shear behavior of MR materials for under harmonic loading. Parameters such as matrix materials with different hardness values, powder types, magnetic field, frequency, and deformation were studied. The parameters related to the MR material itself were analyzed with the obtained data. The present study reveals that considering the sensitivity to magnetic field parameter, composite materials having the most suitable properties were produced with Shore 2 hardness value and SQ magnetic powder. It had been observed on increase about 200% at the rate of Shore A10 and A2 as a result of comparing the hardness scale. Also according to the powder rate while there was an increase on worth effect of relative MR, it is seen that the biggest increase had been in SQ powder with 199% worth. When looked some studies in literature, about comparing different hardness values such as matrix materials powder types etc. there aren’t any studies. The state of magnetic field thinks that features such as MR effect, Storage, and Loss modulus haven’t been examined yet.

    Secular variation of magnetic declination for the past 500 years from Empire to Republic in Anatolia

    Maden, Nafiz; Yıldız, Burak

    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.

    Seismic Disturbances and Geodetic Effects: Unraveling the Impact of the Mw = 6.2 Petrinja Earthquake on the Croatian Positioning System CROPOS

    Bjelotomić Oršulić, Olga; Varga, Matej; Yalvac, Sefa

    A destructive Mw = 6.2 earthquake struck NW Croatia on 29 December 2020, ranking among the most hazardous events in the country in the last century. This study assesses the impact of the earthquake on the permanent geodetic stations of the Croatian national positioning system. Using a novel approach, we combined positioning station data with satellite radar data for the first time in a geodynamic study across Croatia. The analysis involved collecting daily solutions data from 11 nearby network stations as well as multi-temporal satellite images before and after the earthquake. The results reveal a significant co-seismic shift, with the Sisak reference station experiencing the largest displacement of 5 cm to the southeast. Stations up to 100 km from the epicenter exhibited horizontal shifts between 1 and 2.5 cm and vertical shifts between 2 and 4 cm. Satellite images confirmed the co-seismic effects on the permanent stations. The study establishes a strong correlation between geodetic and geological findings, suggesting that vertical displacements result from superficial deposit consolidation in the river plains due to the earthquake shaking, while positional displacement reflects tectonic block movements along the activated strike-slip fault system. The late 2020 earthquake may have further relaxed the accumulated strain on the Mt. Medvednica thrust fault system, which had ruptured in early 2020 with a lower magnitude than expected.

    The effects of psychosocial interventions applied to forensic psychiatry patients on social functioning and anger level: a meta-analysis study

    Emirza, Elif Güzide; Gülirmak Güler, Kübra; Uzun, Sevda

    This study was conducted to determine the effects of psychosocial interventions on social functioning and anger levels in forensic psychiatry patients. Data for this meta-analysis study were gathered by searching databases such as PubMed, Web of Science, EBSCOhost, Google Scholar, and YÖK Thesis Center, without any year restriction, from September to December 2023. After a thorough review, 12 studies were deemed appropriate for the analysis. The findings of this meta-analysis indicate that psychosocial treatments administered to forensic psychiatry patients led to an increase in their level of social functioning (SMD: 0.513, 95% CI: 0.072–0.995; Z = 2.280; p <.05) and a decrease in their level of anger (SMD: −0.701, 95% CI: −1.301 to −0.100;Z = −2.287; p <.05). It was also observed that the effectiveness of the psychosocial intervention was not influenced by the type of psychotherapy, the country where the study was conducted, or the duration of the treatment. Psychosocial interventions for forensic psychiatry patients positively affect the mental health of individuals.
