The aim of this study was to investigate the effects of chiropractic high velocity low amplitude (HVLA) sacroiliac and lumbosacral manipulation on the sprint, jump racing and jumping performance of amateur soccer players with asymptomatic dysfunction of the sacroiliac and lumbosacral joints. The 20-m sprint, 20-m jump racing and horizontal jumping distance of the soccer players analyzed in this study were measured before and after the applications. Sprint and obstacle course racing time were measured by stopwatch and video recordings. In total, 30 patients were included in the study. The participants were divided into 2 groups each with 15 members and were randomly selected. A sham manipulation was applied to the control group and chiropractic HVLA lumbosacral and sacroiliac manipulation was applied to the experimental group. The 20-m sprint time of the control group decreased from 3.49 & x202f;s to 3.46 & x202f;s. In the experimental group the 20-m sprint time decreased from 3.44 & x202f;s to 3.22 & x202f;s. The sprint values of the experimental group were statistically significantly faster than the control group (p & x202f;< 0.05). In the control group the 20-m obstacle course time decreased from 3.87 & x202f;s to 3.79 & x202f;s. In the experimental group the 20-m obstacle course racing time decreased from 3.75 to 3.60 & x202f;s. There was no statistically significant difference between the two groups (p & x202f;> 0.05). In the control group the horizontal jump distance increased from 266.93 & x202f;cm to 268.80 & x202f;cm. This score increased from 261.13 & x202f;cm to 267.80 & x202f;cm in the experimental group. Comparison of the horizontal jumping distance revealed that the experimental group had a statistically significant better performance than the control group (p & x202f;< 0.05). Ziel dieser Studie war es, die Auswirkungen der chiropraktischen Iliosakral- und Lumbosakralmanipulation mit hoher Geschwindigkeit und niedriger Amplitude (HVLA) auf die Sprint-, Sprungrenn- und Sprungleistung von Amateurfußballspielern mit asymptomatischer Dysfunktion der Iliosakral- und Lumbosakralgelenke zu untersuchen. Die in dieser Studie analysierten 20-m-Sprint, 20-m-Sprungrennen und die horizontale Sprungweite der Fußballspieler wurden vor und nach den Anwendungen gemessen. Die Zeiten der Sprint- und Sprungrennen wurden mittels Stoppuhr und Videoaufnahmen gemessen. Insgesamt wurden 30 Patienten in die Studie eingeschlossen. Die Teilnehmer wurden in 2 Gruppen mit je 15 Mitgliedern aufgeteilt und nach dem Zufallsprinzip ausgewählt. In der Kontrollgruppe wurde eine Scheinmanipulation und in der Versuchsgruppe eine chiropraktische lumbosakrale und sakroiliakale Manipulation mit „high velocity low amplitude“ (HVLA) angewendet. Die 20-m-Sprintzeit der Kontrollgruppe verringerte sich von 3,49 auf 3,46 s. In der Versuchsgruppe sank die 20-m-Sprintzeit von 3,44 auf 3,22 s. Die Sprintzeiten der Versuchsgruppe waren statistisch signifikant schneller als die der Kontrollgruppe (p0,05). In der Kontrollgruppe erhöhte sich die horizontale Sprungweite von 266,93 auf 268,80 cm. In der Versuchsgruppe stieg dieser Wert von 261,13 auf 267,80 cm. Der Vergleich der horizontalen Sprungwerte ergab, dass die Versuchsgruppe eine statistisch signifikant bessere Leistung als die Kontrollgruppe aufwies (p

The purpose of this study is to examine scientific publications about Geography Education in terms of bibliometric indicators. Case study method, one of the qualitative research methods, was applied in this study. The scanning range of bibliometric data obtained from the WoS database generated by Clarivate Analytics covers the dates between 1975 and March 2020. The bibliometric analysis technique was conducted in the study. As a result of the analyses, it was revealed that 559 of 64,874,978 studies registered in the WoS database between 1975 and 2020 were the studies related to Geography Education. It was also observed that 196 (35.06%) of these records were in the education / training research category. Through the analyses, it was concluded that the most common type of publication related to Geography Education was the articles with a total number of 196. Moreover, it is seen that approximately 106 of the published articles have been published during the years between 2016 and 2020. This rate indicates that the educational researches related to Geography Education have increased in recent years. In addition, at the end of the analyses, it was comprehended that there are 330 different authors contributing to the related field. It was determined that a total of 535 different keywords were utilized in 196 articles, and the most effective journal was the “Journal of Geography and Environmental Education”. Besides, it is observed that the researchers from 25 different countries have published some articles that contribute to the field. In this regard, the most active country is the United States, and it is respectively followed by Britain, Australia, and Turkey. That Turkey with 18 articles takes place at the 4th rank among the 25 different countries indicates that some comprehensive studies related to this field are carried out.

The aim of this study is to determine the scope validity of the graph drawing interpretation skill checklist that can be used in social studies teaching. The literature review was made while the draft skill checklist was prepared at first. There have generally been some graph drawing and interpretation skill checklist studies at secondary and higher education levels. However, a graph drawing and interpretation skill checklist prepared for the social studies course at the primary education level has not been found. In the next step, items of the graph drawing and interpretation skill checklist were prepared. It has been benefitted from the literature on the graph drawing and interpretation for this. Attention has been paid to the preparation of items that assess the graph drawing and interpretation skill at the elementary education level. The scope validity of the items was analyzed employing the technique developed by Lawshe (1975) based on assessments of 10 specialists in their field. Analysis results show that the scope validity ration of the skill checklist was sufficient, thereby being workable in assessing the graph drawing and interpretation skill in social studies teaching.

The current study aims to determine prospective teachers’ opinions about WebQuest applications by both introducing them to the WebQuest teaching materials and obtaining their experiences in the WebQuest design process. This study employs phenomenology as a qualitative research approach. The study was conducted in the spring semester of the 2017-2018 academic year with the third year undergraduate students in the social studies education department of a state university in Ankara. Two different data collection tools, a Peer Evaluation Form and an Interview Form, were used. Content analysis was used to analyze the data obtained. According to the findings of the study, social studies preservice teachers think that teacher supervision of Webquest teaching activities is advantageous. Preservice teachers defined the specific principles of WebQuest teaching activities as a weak factor. Additionally, preservice teachers emphasized that WebQuest teaching activities are difficult to implement in environments where Internet and computer facilities are not available. Even though almost half of the participants stated that they wanted to include WebQuest teaching activities in their classes when they started the teaching profession, they expressed about their concerns.

This study deals with the evaluation of the Weather Research and Forecast (WRF) model’s parameterization schemes when used for global horizontal irradiation (GHI) forecasts, to assess the feasibility of solar energy utilization. The study area is the southeastern Anatolia (SEA) region of Turkey, with favorable weather conditions for solar energy generation. The results indicate that the values in the hourly output of GHI in the model were overestimated for all configurations at all stations compared to observations. The relative mean bias error values at five stations for all configurations vary between 10-21% for clear-sky and 17-30% for partly-cloudy conditions. Similarly, the relative RMSE values at the five stations vary between 20-39% for clear sky and 41-70% for partly-cloudy conditions. However, there are noticeable differences among the various configurations of the WRF parameterizations.

Coşkun, Reşat (Arel Author), Background: In our study, it was aimed to research the effect of kinesiological tape on pain, shoulder movement angles, and daily life activities. Methods: The control group (n:15) was applied with classical physiotherapy program including ultrasound, tens and exercise. The experiment group (n:15) was applied kinesiological-tape for seven days in addition to classical physiotherapy and rehabilitation program. Pretreatment and post-treatment pains of the patients were measured by using Visual Analog Scale (VAS), the goniometer was used to measure the shoulder ranges, Constant-Murley measured daily life activity levels, and DASH-T measured shoulder disability level.Results: As the VAS scores of the control group inactivity reduced by 11,21 points, the scores of the experiment group decreased by 24,53 points. The difference in scores between the two groups is significant statistically (p0,05). For shoulder movement opening, all records of the experiment group are significantly better than that of the control group, except the flexion increase. Conclusion: Kinesiological tape application ensuring a reduction in pain for rotator cuff injury in a shorter period is a treatment also providing significantly better results in shoulder movement recovery, increase in functionality, and a decrease in disability.

Ground-based solar-radiation observations have rather high random errors, which were sourced from maintenance, calibration and/or inaccurate instruments in Turkey. Satellite-based radiation data obtained from the National Aeronautics and Space Administration (NASA) were compared with reliable ground observations, and it was found that the global solar incident insolation data of the NASA Surface Meteorology and Solar Energy (SSE) dataset is usable, with a rather low mean relative error of about 4%. Therefore, monthly and annual spatial distribution over Turkey and solar-radiation time series were analysed in order to detect the potential of solar radiation and to find out variations and trends, respectively.

Solar energy applications need reliable forecasting of solar irradiance. In this study, we present an assessment of a short-term global horizontal irradiance forecasting system based on Advanced Research Weather Research and Forecasting (WRF-ARW) meteorological model and neural networks as a post-processing method to improve the skill of the system in a highly favorable location for the utilization of solar power in Turkey.

The optimum values of the section variables (side slope, bottom width, flow depth, and radius) for triangular, rectangular, trapezoidal, and circular channels are computed by minimizing the cost of the channel section. Manning's uniform flow formula is treated as the constraint of the optimization model. The cost function is arranged to include the cost of lining, the cost of earthwork, and the increment in the cost of earthwork with depth below the ground surface. The optimum values of section variables are expressed as explicit functions of unit cost terms. Unique values of optimum section variables are obtained for the case of minimum area or minimum wetted perimeter problems. Key words: open channel design, optimization, minimum cost, best hydraulic section.
