Aim: Based on these ideas, our research aims to measure the attitudes of cycling athletes in Elazig province towards ecorecreation.. Methods: A total of 178 athletes from 242 cycling athletes, including cycling sports clubs, associations, and individual athletes in Elazig province, participated voluntarily. It consists of 31 substances and 6 sub-dimensions developed by Ayyildiz and the 'Personal Information Form' prepared by the researchers as a data collection tool. Attitude Scale Towards Ecorecreation(ASTE), which was created in a 5-point Likert type format, was used. Spss 22.00 package program was used for the analysis of the data and the level of significance was determined as p<0.05. In the study, t-test analysis was applied to determine the significance of the differences between two groups and ANOVA was applied to determine the significance between more than two groups. Pearson correlation analysis was used to determine the direction and severity of the relationship between variables. Results: As a result of the research, there was a semantic difference in the individual and environmental sensitivities of licensed cycling athletes. A significant difference was observed in the Attitudes and Behavior towards Ecorecreation sub-dimensions of the athletes who are interested in another nature sport. Conclusion: The increase in positive behaviors towards nature has clearly become clear that it is directly related to being in nature. Accordingly, researchers believe and draw attention to the fact that in order to increase the positive effect on nature, it is necessary to be intertwined with nature and to adopt it.

Tosun, Sibel; Onur, Fulya Eslek
Morphological awareness (MA) has been regarded as a profoundly important aspect of enhancing both vocabulary breadth and depth. As one of the predictors of morphological competence, knowledge of derivational suffixes has a crucial place among all morphemes because they have the ability to change word class. This descriptive study, which employed a quantitative approach, aimed to investigate students' receptive and productive knowledge of derivational class-changing suffixes and to identify to what extent they can produce appropriate derivatives in different word classes. Predictive roles of receptive and productive MA on writing achievement are also a subject of the current study. To achieve the purpose, 50 undergraduate EFL students studying at the School of Foreign Languages at a state university, whose ages ranged between 18 and 22 participated in the study. The results of the study indicated that the participants were significantly better at the receptive task than in productive task. It has also been found that productive MA uniquely predicts writing performance scores. The current study is noteworthy in that it aims to shed light on the strengths and weaknesses of the learners' morphological knowledge as well as provide insights for similar settings on the areas to specifically focus on while teaching derivational suffixes.

Kutlu, Banu; Dorucu, Mustafa
We determined the toxic effects of seven metals. copper (Cu), manganese (Mn). zinc (Zn), cobalt (Co). molybdate (Mo), lead (Pb), and cadmium (Cd) on the microalgae Tefraselmis chuii (Butcher, 1959). We exposed 50 mL of cultivated microalgae (f/2 Gaillard) in the exponential growth phase. with three replicates, to concentrations of 0 (control). 0.1, 1.0, 5.0, 10, 25. and 50 g L of each metal for 72 hours. The cellular count was recorded daily to evaluate any potential lethal effects. An increase in cellular density was seen in the control treatment. All treatments exposed to metals showed a logarithmic increase in cell density within 48 hours, with a cellular decrease that became evident later on. This study result with an insignificant decrease at low concentrations of Cd, Pb, and Cu at 24 hour was probably attributed to their use as micronutrients at these low concentrations. The most lethal effect was observed with Cd treatment, which killed 50% of the microalgae population at a concentration of 0.62 mu g L-1. In this study, this concentration was three times lower than that of lead and mercury. while being ten times lower than that of cobalt and molybdate. To elucidate the adverse effects on seawater environments, the microalgae Tetraselmis chuii is recommended as a model species.

BackgroundThe aim of this study is to histologically and biomechanically investigate the effects of local PRP and ozone therapy (O2O3) on tendon-to-bone healing in a rabbit model of the supraspinatus tendon tear.MethodsFour groups were formed to have seven rabbits in each group: repair, R; repair + PRP, RP; repair + ozone, RO; and repair + PRP + ozone, RPO. The supraspinatus tendon was detached by sharp dissection from the footprint and an acute tear pattern was created. Thereafter, tendon repair was performed with the transosseous technique. In the RP group, PRP, and in the RPO group, PRP + O2O3 mixture was injected to the tendon repair site. In the RO group, O2O3 gas mixture was injected into subacromial space three times a week for a total of 4 weeks. The study was ended at postoperative 6th week.ResultsWhen compared with the R group, a statistically significant increase was observed in the biomechanical strength of the RP and RPO groups. The highest increase in biomechanical strength was detected in the RPO group. The histology of the RO and RPO groups showed better collagen fiber continuity and orientation than the R and RP groups.ConclusionsThe results obtained from this study show that the ozonized PRP can be used as biological support to increase tendon-to-bone healing. However, these results need to be supported by clinical studies.

In this study, it was aimed to determine the factors affecting parents' share on social media about their children. This is a qualitative study which was conducted with the participation of 88 parents. Data were collected through an online questionnaire consisting of open-ended questions. It was revealed that most of parents participating in the study posted about their children on social media. It was determined that parents mostly pay attention to the children's appearance and privacy while sharing posts regarding their children on social media. It has been observed that among the factors affecting sharing, the factor of staying in contact with the social environment of the parents stands out. Besides, some parents' desire to make special days permanent and the fact that their shares make them feel happy were other factors which draw attention. It was concluded that the parents did not have sufficient knowledge about the legal processes that may arise from their social media posts.

Akbaba, Emel; Aydin, Sevinc; Sanyurek, Nesrin Karaca
Vitis vinifera L. is cultivated throughout the World including Turkey which is one of the largest producers of grape. Grape is consumed as fresh or dry fruit as well as used in the wine industry in which good quality of grapes are preferred. Grape is also a part of the traditional Mediterranean diet which is linked to a low risk of cardiovascular and degenerative diseases. Kohnu is a geographically labeled type of grape cultivated in the eastern cities of Turkey. In this study, Kohnu grapes harvested from two different cities of Turkey were compared through phenolic compounds, phytosterols, vitamins, fatty acids, and antioxidative properties. The concentrations of phenolic compounds in the sample from Elazig were obtained to be significantly higher as compared to the sample from Malatya. Especially vanillic acid was found to be much higher in Elazig samples. The concentrations of fatty acids especially palmitic acid, palmitoleic acid, oleic acid, and linoleic acid were obtained significantly higher in Elazig samples as compared to Malatya samples. Vitamin and phytosterol concentrations of the samples from Elazig were also determined as higher as compared to Malatya samples. Significantly higher antioxidant activity of Kohnu grape seeds from Elazig was obtained via DPPH radical scavenging activity and MDA levels. The antioxidant profile of Kohnu grape seeds of Elazig samples could be related to phenolic composition and vitamins.

Ates, Mehmet; Yilmaz, Ersen; Kar, Bulent; Durukan, Ilknur Kars
Recent advancements in nanotechnology have garnered increasing attention due to the improvements in producing and utilizing particles whose sizes are extremely small. There is particular interest in metal nanoparticles due to their distinctive properties. Silver nanoparticles (Ag-NPs) have been of particular interest owing to their unique electrical, optical and physicochemical properties as well as their biomedical applications. Ag-NPs are the fastest growing class of nanoscale materials because of their antibacterial activities. They are now considered to be the next generation antimicrobials. Today, owing to their disinfectant properties, Ag-NPs are extensively used in numerous consumer products, including disinfecting medical devices and home appliances, paints, optical devices, plastics, textiles, soaps and laundry detergents, cosmetics, health-care products, as well as in food packing and food products as preservative and anti-caking agents. Despite their widespread usage, the products containing Ag-NP additives are a serious environmental and human health concern because of their toxicity. Studies on cell and bacterial cultures have shown that Ag-NPs are toxic; and the toxic effects are mainly due to the dissolved Ag ions when Ag-NPs degrade in water. In this study, considering the criteria outlined above, the purpose of the study and Ag-NPs were chemically synthesized in the laboratory environment and modified as chitosan coating. UV-Vis spectroscopy, transmission electron microscopy, scanning electron microscopy, X-ray crystallography and zeta potential analysis were used to characterize the silver nanoparticles.

Ustundag, Aybike; Gencer, Cetin
The number of forest fires has increased significantly in recent years. Interventions to forest fires from air and land are very difficult and dangerous. In addition, since these interventions are time-consuming, forest fire can spread to a much wider area. In this study, an automatic fire extinguishing system was designed using SCADA for 5 forest regions up to 5 hectares. In the event of a fire in the system, the smoke sensor in the fire area becomes active and the IP camera image in this area is displayed on the screen. The pressurized water flushing tap, which automatically rotates 360 degrees, works in the area. If desired, automatic operation can be canceled and manually adjusted water flushing tap can be operated. The system gives a warning when the tank water drops below 1 ton. The aim of this study is to automatically intervene early in any fire that may occur in the forest and to control the fire before it spreads.

In this study, three hybrids of Origanum (Lamiaceae) were examined in detail using morphological, karyological, palynological and molecular approaches. One of the three hybrids, O. × aytacii, is here described for the first time, and is compared with its putative parents, O. sipyleum and O. vulgare subsp. hirtum. In addition to morphological, karyological and palynological features, we also examined nuclear ribosomal DNA (ITS) sequences of O. × intermedium (O. onites × O. sipyleum), O. × intercedens (O. onites × O. vulgare subsp. hirtum) and their purported parental species that share the same area with the new hybrid. Pollen grains were hexacolpate and isopolar. The range of Polar/Equatorial ratio (P/E) of pollen for investigated taxa varied from 0.74 to 0.99. All investigated taxa are diploid with a chromosome number as 2n = 30. According to molecular results, O. × aytacii was the most polymorphic taxon. In addition, DNA sequences showed that O. × intercedens was more similar to O. vulgare subsp. hirtum than to O. onites, and O. × intermedium was more similar to O. onites than to O. sipyleum. Furthermore, O. onites and O. vulgare subsp. hirtum have many different ITS haplotypes, probably resulting from backcrossing with different individuals. Results obtained in this study demonstrate that hybridization has played a major role in the process of Origanum speciation.

Gul, Muhammet; Guneri, Ali Fuat
The increased focus of people on the quality of health care in recent years has led hospital owners to develop strategies and policies to improve medical services through the establishment of new hospitals. For hospitals to be competitive, the hospital's location and proximity to potential patients are considered crucial factors in establishing new hospitals. In this context, evaluating and selecting the most suitable hospital location to establish a new hospital from the multicriteria decision-making (MCDM) perspective is a priority for the entrepreneurs or government to gain a competitive advantage. Therefore, this study aims to present a systematic literature review of the hospital location selection problem considering the applied methods and application areas. The preferred reporting items for systematic review and meta-analysis statement (PRISMA) are used as a reference framework. Initially, known electronic databases (Web of science, IEEEXplore, Scopus, Science direct, and Google Scholar) were searched up to the early 2021. A number of 47 articles are selected and analyzed under this systematic framework based on inclusion-exclusion points. State-of-the-art developments in adopting MCDM methods and their fuzzy extensions are summarized. All the articles have been examined in a systematic taxonomy to find answers to six research questions (trend, country of origin, outlet journal, MCDM methods used, MCDM environment and criteria type, and decision criteria used). Results show that (1) AHP and GISbased MCDM models are the most contributing approaches to the solution of this problem, (2) location selection criteria are mostly cost, demand, environment, population, government, competition in the market, and distance to some important places, (3) the fuzzy structure is also preferred in addition to the MCDM structure depending on the crisp data type, and (4) the location selection criteria are mostly considered subjective. We pay attention to promising directions that can dominate future research in this field from a methodological or applicability perspective. This study shows the current views and opportunities for researchers and practitioners and acts as a guide to encourage more creative studies in this field.

The objective of this study were to identify the fatty acid composition for decanoic (C10:0), tridecanoic (C13:0), myristic (C14:0), pentadecanoic (C15:0), palmitic (C16:0), stearic (C18:0), oleic (C18:1n9c), linoleic (C18:2n6c), arachidic (C20:0), arachidonic (C20:4n6), heneicosanoic (C21:0), erucic (C22:1n9) and Cis-4,7,10,13,16,19-docosahexaenoic (C22:6n3) acids by Neocallimastix, Orpinomyces, Caecomyces and Piromyces species of rumen fungus during in vitro culture. Fatty acid (FA) profile of anaerobic fungi comprises carbon chains of length ranging from 10 to 22 were analyzed as methyl esters. Analysis of fatty acids was performed using Gas Chromatography-Mass Spectrophotometer (GC-MS). FA measures are presented as proportions of relative amounts (% total fatty acid). The highest amounts of fatty acids for all samples were found as myristic (C14:0) acid. The tridecanoic (C13:0) acid represented the second abundant FA in the fungi in all experimental groups. Stearic acid (C18:0) was the third major fatty acid for isolates investigated in the current study. In addition, another fatty acid was palmitic (C16:0) acid with relative amount representing >20% of total FA in all samples. Pentadecanoic (C15:0) acid could not be found in any other samples except Orpinomyces sp. (GMLF5). It is concluded that biohydrogenation of fatty acid composition by anaerobic gut fungi are very variable.
