This study aimed to explore the pre- and postoperative differences in quality of life and perceived social support of Female-to-Male transsexual patients who underwent mastectomy and complete hysterectomy. Sixty-three Female-to-Male female individuals who underwent complete hysterectomy and mastectomy between November 2019 and November 2020 were included in this study. Data were collected using the Personal Information Form, Multidimensional Scale of Perceived Social Support, and the World Health Organization Quality of Life Scale Short Form. The pre- and postoperative perceived social support mean scores of patients were 57.2 ± 9.0 and 74.9 ± 7.3, respectively. The pre- and postoperative quality of life mean scores of patients were 76.9 ± 8.3 and 107.8 ± 10.1, respectively. There were statistically significant differences between the measurements (p <.05). In addition, the patients whose education level was primary school, whose income was less than their expenditure, whose father was a primary school graduate, whose family had a strict family opinion on sexuality, whose family had a traditional view, and who had a high body mass index were found to have higher postoperative social support perceptions and quality of life. The patients’ postoperative quality of life and perceived social support improved after sex reassignment surgery.

Göçmen, Elifcan
Coronavirus disease 2019 (COVID-19) brings about severe disruptions for human living, economics, and environmental balance. This pandemic has boosted the demand for personal protective equipment (PPE) and thus, medical wastes. Thus, a research hypothesis is stated whether it would be possible to provide more efficient distribution and inventory planning to optimize the PPE availability in a fuzzy environment. To confirm the hypothesis, in addition to addressing a scientific novelty considering integration of linear programming with fuzzy parameters, named as the Jimenez’s method and clustering heuristic methods, the practicality of these approaches is provided on a real case study and generated instances from Turkey. The computational results reveal that clustering the 32% of the hospitals ensures optimum total cost and solution time while feasibility degree changes between 0, 4, and 1 values of the Jimenez are not more effective on the results. Improved cost results reveal the economic importance of the healthcare supply chain management and optimal PPE distribution and inventory planning can break down the disease propagation and reduce the detrimental impacts on human life. The proposed approach, for the first time, ensures practical and theoretical insights of distribution and storage decisions across disciplines, namely, engineering and health-care organization authorities.

Basit, Gülden; Erkuş Küçükkelepçe, Gülhan; Arslan Şeker, Sevda
Introduction: Professional values give meaning and direction to clinical practices by providing a philosophical framework for nursing practices. The internalization of professional values is quite effective in providing professional service and is very important in terms of service quality. Design: This descriptive study has been conducted to determine the relationship between nurses' professional values and caring behaviors. Methods: A total of 176 nurses participated who worked in hospitals in this study. The data were collected online using the Nurse Information Form, Nurses Professional Values Scale-Revised (NPVS-R), and Caring Behaviors Assessment Tool Nursing Version-Short Form (CBAN-SF). Data analysis was performed using SPSS software, the Mann–Whitney U test, the Kruskall–Wallis test, and the Spearman correlation coefficient. Results: Of the nurses participating in the study, 66.5% are between the ages of 21–30, 80.7% are female, and 71% are university graduates. No statistically significant difference was found regarding professional values between the mean scores from the NPVS-R and CBAN-SF in terms of the nurses' age, gender, position, working style, clinic at which they work, or their educational status. The nurses scored high on the NPVS-R and CBAN. A moderate, significant, and positive relationship was found between nurses' overall scores on the NPVS-R and CBAN-SF. Conclusion: As nurses' perceptions of professional values increase, their perception toward assessing care behaviors also increases. In addition, a relationship exists between nurses' education levels and assessment of care behaviors and between their work experience and their perceptions of professional values. Conducting studies on the subject using different designs is recommended.

Raza, Ali; Khan, Umair; Eldin, Sayed M.; Alotaibi, Abeer M.; Elattar, Samia; Prasannakumara, Ballajja C.; Akkurt, Nevzat; Abed, Ahmed M.
Given the importance and use of electrically conducted nanofluids, this work aims to examine an engine-oil-based nanofluid including various nanoparticles. In the current study, a fractional model for inspecting the thermal aspect of a Brinkman-type nanofluid, composed of (molybdenum disulfide (MOS2) and graphene oxide (GO) nanoparticles flows on an oscillating infinite inclined plate, which characterizes an asymmetrical fluid flow, heat, and mass transfer. Furthermore, the Newtonian heating effect, magnetic field, and slip boundary conditions were taken into account. The objectives for implementing the Prabhakar-like fractional model are justified because this fractional algorithm has contemporary definitions with no singularity restrictions. Furthermore, the guided fractional model was solved using the Laplace transform and several inverse methods. The obtained symmetrical solutions have been visually analyzed to investigate the physics of several relevant flow parameters on the governed equations. Some exceptional cases for the momentum field are compiled to see the physical analysis of the flowing fluid symmetry. The results show that the thermal enhancement can be progressively improved with the interaction of the molybdenum disulfide-engine oil-based nanofluid suspension, rather than with the graphene oxide mixed nanoparticle fluid. Furthermore, the temperature and momentum profiles enhance due to the factional parameters for molybdenum disulfide and the graphene oxide-engine oil-based nanofluid suspension. This study’s graphical and numerical comparison with the existing literature has shown a very close resemblance with the present work, which provides confidence that the unavailable results are accurate. The results show that an increase improved the heat transmission in the solid nanoparticle volume fractions. In addition, the increment in the mass and heat transfer was analyzed in the numerical evaluation, while the shear stress was enhanced with the enhancement in the Prabhakar fractional parameter α.

Goksu, Ali; Omac, Basri; Sabancı, Serdal
Bulgur is a nutritious, healthy, and partially cooked food product with long shelf life and produced from wheat grains. In the present study, ohmic heating (OH) was used to cook bulgur as an alternative method to conventional cooking in case of bulgur pilaf due to its advantages including shorter heating time, uniform heat distribution in food, and higher energy efficiency. Bulgur was cooked in 0.1% salt solution to evaluate the effect of OH at various voltage gradients (10, 13, 16, and 19 V/cm) and conventional cooking processes on the textural properties of bulgur and energy consumption. The results showed that for the OH process, the total energy consumption for the cooking of bulgur reduced by approximately 80% compared to that for conventional cooking. In addition, the voltage gradients were significantly related to the cooking time, a crucial parameter for the water absorption of bulgur (p < 0.05). Novelty Impact Statement: Pre-cooked bulgur must be cooked in water by using electric or flame equipment before consumption. Nevertheless, in these systems, the cooking process consumes a pretty long time and causes a vast amount of waste energy. Therefore, alternative methods are needed to save time and energy. Thus, the ohmic heating was used as an alternative cooking process for bulgur prior to consumption.

Healthcare professionals have a significant role to play in the early diagnosis of child abuse and neglect (CAN), which is important in terms of protecting children's health. The study aimed to measure the change in the participants' level of diagnosing the risks and symptoms of CAN before and after the training by providing a training program to healthcare professionals including the signs of CAN, symptoms and procedures to be followed in this case. All healthcare professionals working in a State Hospital and Family Health Centers in Tunceli, Turkey, and who volunteered to participate in the study were included in the study (n = 125). The data were collected before and after the training by using the Personal Information Form and The Diagnosis Scale of the Risks and Symptoms of Child Abuse and Neglect (DSRSCAN). 39 participants (31.2%) reported that they had previously suspected CAN, and 35 (28%) stated that they had encountered CAN before. The mean DSRSCAN score of the healthcare professionals included in the study before the training was 3.38 (lowest =2.37, highest =3.55), while after the training, it went up to 3.60 (lowest =2.76, highest =5.00), and the difference between the pre-training and post-training DSRSCAN scores was determined to be statistically significant (p < 0.001). It was determined that when healthcare professionals were trained on CAN, their awareness could be further strengthened. Hence, training programs for healthcare professionals on diagnosing and reporting CAN should be updated and increased.

Artuğer, Fırat; Özkaynak, Fatih
What makes artificial intelligence techniques so remarkable in the field of computer science is undoubtedly their success in producing effective solutions to difficult computational problems. In particular, metaheuristic optimization algorithms are a unique example of using artificial intelligence techniques to generate approximate solutions to problems that cannot be solved in polynomial time, called NP. Obtaining a substitution box (s-box) structure that will satisfy the desired requirements in cryptography is an example of these NP problems. In the literature, it is a hot topic to optimize the s-box structures obtained from chaotic entropy sources with heuristic algorithms to improve their cryptographic properties. The study with the highest nonlinearity value (110.25) based on optimization algorithms to date has been published in 2020. In this study, a method with a higher nonlinearity value than the algorithms previously proposed in the literature is developed. It has been shown that the nonlinearity value can be increased to 111.75. These results will be a basis for new research on the chaos-based s-box literature and will motivate new studies to develop alternative optimization algorithms in the future to obtain s-box structures based on the random selection equivalent to the AES s-box.

This paper carried out numerical investigations on the flow and heat transfer characteristics of a phase change with two-dimensional rotation of the three-dimensional paraffin (RT -27)-filled rectangular encapsulated container (PCM-REC) in space. A three-dimensional transient numerical heat transfer model was established and the enthalpy method was used to simulate the solid-liquid phase transition process and the flow evolution at the PCM interface. In this paper, the solid-liquid interface distribution, temperature distribution and melting time of PCM in PCM-REC heated at a constant temperature on one side were compared when rotated at different angles (0°, arctan (0.4), 2arctan (0.4) and 90°) along the heating direction and vertical heating direction. Results demonstrated that the peak value of maximum natural convection velocity increased from 0.0072 m/s to 0.0184 m/s with increasing radial height when PCM-REC was rotated in vertical heating direction. When PCM-REC was rotated in two dimensions by the same angle, the melting time was fastest when γ was an obtuse angle, and with the increase of the obtuse angle, the melting time shortened from 17 min to 6 min; when γ was an acute angle, the melting time was slowest, and with the decrease of the acute angle, the melting time lengthened from 49 min to 288 min.

Background: Many implant options could be preferable for fixation after osteotomy in varus knee medial compartment arthrosis. Due to usage characteristics, it is important to compare the biomechanical properties of them. For this purpose, we aimed to examine three different implant types biomechanically in our study. Methods: Ovine tibiae undergoing medial open-wedge high tibial osteotomy were fixed in vitro with three different implants using an angular wedge plate, a metal block plate and an external fixator system. The fixed ovine tibiae were subjected to axial tensile, axial loading and three-point bending tests in a test machine. All biomechanical tests were repeated five times, the maximum and minimum values were ignored, and the average values of the remaining three test results were taken into account. The test results were interpreted after converted into force-elongation curves in Trapezium-X software. Findings: Biomechanical test results revealed some differences between implant types. While the metal block plate had the highest axial tensile strength value, it was the fixation group showing the lowest strength in axial load tests. The used fixator system was the highest strength in axial load tests and the lowest strength in axial tensile tests. Interpretation: Considering the clinically significant forces related to the biomechanical stability of the three different implants used for high tibial osteotomy, the fixator system would appear to be slightly superior, although it should be noted that torsional forces, as well as parameters that could change in living tissue, might affect the results.

Yilmaz, Ersen
In this study, nonmiscible polyvinyl chloride (PVC) and polymethyl methacrylate (PMMA) polymers were made miscible by using MA-St-MMA terpolymer as a compatibilizer. Maleic anhydride-styrene-methyl methacrylate (MA-St-MMA) terpolymer was synthesized in our laboratory and used. The synthesized terpolymer was determined by FT-IR spectroscopy. Equal mass PVC/PMMA mixture samples were prepared in series and the compatibilizer terpolymer varying between 2% and 10% by mass was added to the samples and the effect of the added terpolymer on the miscibility was determined viscometrically, thermally, mechanically and, visually. With the addition of the compatibilizer, the two components in the mixture behave like a single polymer with a single glass transition temperature (Tg) and the mixture became compatible. As a result of viscometric experiments, it has been determined that with the added MA-St-MMA terpolymer, the Δb value derivated from the Krigbaum-Wall equation which is the miscibility parameter of a mixture shifted into the positive (+) zone indicating that the two polymers became miscible. By visual analysis, it was observed that the added terpolymer reduced the opaque appearance and the phase separations of the mixture. From the tensile test, a significant improvement in impact toughness was observed. When all the data obtained were evaluated, it was determined that the synthesized MA-St-MMA terpolymer was a suitable compatibilizer for the mixture of PVC and PMMA.

Barramundi, Lates calcarifer is one of the commercial fish in Indonesia and other Southeast Asian countries. The species inhabits the coastal waters and is vulnerable to changes in the terrestrial environment due to coastal degradation, pollution, and global warming. The increase in temperature as a consequence of global warming affects the distribution and survival of aquatic organisms including fish. Therefore, this study aims to examine the effect of increasing water temperatures on the physiological conditions and gill histology of barramundi. The fish were exposed to eight levels of water temperature, ranging from 28oC to 35oC, for 15 days. The initial temperature was 28oC, which increased gradually by 1oC per 12-hour. Blood samples were taken at the end of the experiment for hemoglobin, glucose, cortisol, erythrocytes, leucocytes, and blood abnormality analyses. Gill samples were also taken for histological analysis. The results showed that water temperature significantly affected the level of glucose, cortisol, and erythrocyte cells (P<0.05), but did not influence hemoglobin levels and survival rate (P>0.05). A rapid increase in glucose and cortisol levels was also discovered at a temperature of 31oC above. The highest erythrocyte cell count was found at 35oC, gill cell abnormalities were occurred at temperature of 31oC and above, and the blood abnormalities increased linearly with water temperature. Based on these results, it is concluded that the water temperature did not affect the survival rate but the increase in temperature causes intense physiological stress.
