The aim of this study was to investigate the effects of diaphragmatic kinesiology taping on physical fitness parameters in university students. Twenty male university students participated in this study voluntarily. Muscle facilitation technique was applied on back and abdominal region coinciding diaphragm muscle. For sham application, same tape material was applied without a special stretch or technique. International Physical Activity Questionnaire Short Form (IPAQ-SF), 2 km walking test, prone plank, side plank, Sorenson test and Standing stork test were used for evaluation. After the first evaluation, we waited 72 hours for the second application. Firstly, 10 participants had tape application and the other half had sham taping. In the second session, we changed the application. In the taping and placebo applications, a significant relationship was found between prone endurance test values before and after application (p<0.05). In the kinesio tape and placebo applications, a significant relationship was found in 2 km walk performance compared to untaped condition evaluation before and after the application (p <0.05). In the before-after evaluations within the group, a significant difference was found in the kinesio tape and placebo applications in the 2-kilometer walking test, but there was no statistically significant difference in the comparisons between the kinesio tape and placebo applications.

Basoglu, Mustafa Engin
Maximum power point tracking (MPPT) strategy is one of the major parameters affecting efficiency in photovoltaic (PV) systems. In this paper, distributed MPPT approaches are compared with central mode MPPT. Advantages and disadvantages of submodule level MPPT technique and module level MPPT approach are shown with simulation studies. Comparisons are made with incremental conductance (IC) algorithm. In this context, non-isolated zeta converter is used as a power-processing unit. Effect of the MPPT strategy on the collected energy performance is observed by simulation studies performed in MATLAB/Simulink. It is clear by these studies that energy capture is bigger in submodule level MPPT strategy and module level MPPT with respect to central mode which is seen by simulations. However, central mode MPPT offers cost effective solution because of the low hardware requirements.

Cengiz, Sevil; Uçar, Fahri; Uçar, Meltem; Orhan, Deger; Yigit Gerigelmez, Asuman
Garlic (Allium sativum) is a spice used for centuries for both condiment and medicinal purposes. Studies have shown that it has antibacterial, antiviral, anti-inflammatory, antifungal, antimutagenic, antioxidant, antiallergic, anti-aging, antitumoral and immunostimulatory activities. Activation of caspase3 initiates the caspase activation chain, leading to apoptosis. In this study aimed to determine the apoptotic effect of DMSO-containing aged garlic extracts (AGE) on Myoid Cancer Cell lines (HL-60). Flow cytometry method and spectrophotometric caspase-3 activity analyzes were used using human lymphocyte cells as a control group. The highest apoptotic effect on HL-60 cell lines was observed in aged garlic extracts at a concentration of 12.5 mg/mL (10.9%). It was determined that caspase-3 activity in HL-60 cell lines increased by 1.28 to 3.02 times compared to lymphocyte cells. It was concluded that aged garlic extracts triggered apoptosis by increasing the activity of caspase-3 in HL-60 cell lines. It is thought that the aging of garlic has an anticancer effect and additional studies on this subject may bring new perspectives to cancer treatment.

The aim of this article is to design and model a quadrotor with autopilot system and differential morphing using the Simultaneous Perturbation Stochastic Approximation (SPSA) optimization algorithm. Along with differential morphing, quadrotor modelling and control was also done. Although it is simple in structure, it has a complex structure in terms of model and control. Newton-Euler method was used for the dynamic model. Non-linear motion equations have been converted to linear motion equations. The full quadrotor model was drawn in the Solidworks program. Mass and moment of inertia information was obtained from this model. Simulation model was created by using state space model approach in Matlab / Simulink environment. Proportional integral derivative (PID) algorithm was used as the control structure. Differential morphing and PID coefficients rates were determined with SPSA. With the optimization method, determining the differential morphing rate, PID coefficients and applying it to the quadrotor provides a very innovative method.

Çatal Reis, Hatice; Yılancı, Gulsena
As a result of the development of cities and inclination towards urbanization, natural areas decreased while urban areas increased. In this respect, determination of impermeable surfaces is important for the problems covering; effects of urbanization on natural environment, global environmental variation, urban atmospheric process, human activities and the effects of urbanization on the environment. Remote sensing images are used to examine and classify land cover/uses. Traditional classification methods are mainly divided into supervised classification and unsupervised classification. The aim of this study is to classify land cover/use and to state temporal change using the Support Vector Machines (SVM) approach, which is a supervised classification method. Arnavutkoy district of Istanbul was chosen as the study area for land use and change detection analysis. Landsat 5/7/8 satellite images of Arnavutkoy district were obtained and SVM process was applied to obtain these images. Firstly, four classes were created for each image: urban areas, vegetation, bare soils and wetlands SVM was applied and accuracy analysis was performed to the images classes of which were created before. CAD software and GIS software were used for image processing. The classification accuracy for SVM was found to be 98.66%, 98.31%, 98.95%, 97.99%, 96.37%, 97.90% (from 1995 to 2019). In addition, ROC analysis was used for comparison of accuracy analysis. As a result of this study, land cover/use change of Arnavutkoy district in the last 20 years has been determined. The urban area of the district was 40.99 km2in 1995 and 93.76 km2in 2019. In addition, the impact of the Europe's largest airport on land cover / use has been examined. The results showed that the accuracy of using SVM to classify land use/cover is high. Therefore, it has been proposed that this algorithm is used as an optimal classifier for land use/cover maps.

Şimşek, Ahmet Bahadır
This study addresses the adaptation of the course timetabling problem to the online education system forced by the Covid-19 pandemic. The seating capacity constraint that shapes the timetabling decision in online education conditions loses its validity. It is replaced by a bandwidth constraint that restricts the number of instantaneous connections. Overlapping courses in the same time slot increase the number of instant connections and excessive connections cause technical problems. Bandwidth constraint requires the distribution of total connection in a day over all time slots. However, while this is achieved, the time slots should be allocated fairly to the departments. In this study, a multi-objective mathematical model is proposed that distributes the courses fairly on the day and time slot axis and distributes the total number of connections to time slots in each day as equally as possible. The model adopts the maximum difference minimizing approach and requires solving the objectives sequentially according to the order of them.The model was tested with the real data of the 2020-2021 fall semester of a 7 department faculty. The model has 12084 decision variables and 15567 constraints and an optimal solution gets in approximately 28 minutes. Results were compared with a decentralized and manually prepared timetable. The comparison shows that the model is superior to the manual timetable in the distribution of courses across the day and time slot. Also, the model can reduce the number of students in the peak time slot by 22% compared to manual scheduling.

Kahya, Volkan; Araz, Onur
Tuned mass dampers (TMDs) are used to reduce dynamic vibrations of structures under environmental loads such as wind or seismic excitation. In this paper, the optimum design of nontraditional tuned mass dampers (NT-TMD) attached to a damped main structure under harmonic excitation was investigated. Unlike the traditional TMD, the damping element in NT-TMD is directly connected to the ground. In this study, the effectiveness of NT-TMD on the attenuation of vibrations on the damped main system under harmonic load is investigated. The optimum parameters of the NT-TMD are obtained by using the hybrid pattern search (HPS) technique. According to numerical results, it is seen that non-traditional TMD is more effective than traditional TMD in reducing vibration.
