Bayram, Ozkan
In this study, vertically oriented (3D) graphene nanostructures (VGN) were obtained on Glass and Fluorine doped tin oxide (FTO) substrates at relatively low temperatures (approaximatelly at 400 °C) by using plasma enhanced chemical vapor deposition (PECVD) technique. VGNs were characterized using Raman, Uv–Vis and SEM spectroscopies, respectively. Raman spectroscopy showed that growth temperature significantly affected VGN formation and film quality. The layer structures of these VGNs were also confirmed by Raman mapping. The most important data obtained from this study is that although the applied radio frequency (RF) power is the same, the growth temperature significantly affects the graphene formation and morphologies. This was attributed to the fact that CH4 decomposition was very difficult at low temperatures. The optical transmittance of VGNs ranged from 50% to 95% (at 550 nm wavelength) and their electrical conductivity was also determined to be between 5.94 kohm/sqr and 11.2 kohm/sqr. The electrical and optical properties of VGNs, which have a large surface area, indicated that they may be an alternative material for sensor, solar cell and supercapacitor applications.

Sarikoca, Erem; Yurttaş, Süleyman
The aim of this study is to develop a scale to determine the attitudes of university students towards elderly people. 31 expressions were formed to cover all dimensions of the old discrimination. 400 university students participated in this study. In the analysis of the data, AFA and DFA were used. Cronbach's alpha coefficients were calculated to provide information on the reliability of the scale. With the AFA analysis, the items with the factor load values lower than 0.32 were tried to be scaled and 8 items were subtracted from the scale. For the validity of the scale, DFA was performed and a two-factor scale was obtained. According to the findings obtained from the analysis; RMSEA 0.062, NNFI 0.90 and CFI 0.91. These values showed good agreement between the sub-factors and the scale. According to the general Cronbach Alpha coefficient (0.801), it can be proposed that the scale is quite reliable.

Çelik, Safinur Yıldırım
It is known that in some diseases (SARS, mad cow, pig and bird flu) that have passed from animals to humans have increased in recent years. In consumers, the use of animal proteases in the production of food products leads to concerns about the spread of these diseases. For these reasons, it has been an increase in demand for the product obtained from plant sources. The fact that only a small proportion of commercially available enzymes are herbaceous, have encouraged researchers to search for new herbal protease sources that can be used commercially. In this study, for the first time protease enzyme was purified from the tubers of a Crocus biflorus and characterized. The protease enzyme was purified 86 fold by ammonium sulfate precipitation and ion exchange chromatography. Optimum pH and temperature was found as 5.5 and 50 °C. The values of Vmax and KM were calculated as 47 mg/mL.min and 0.9 g/L, respectively. The molecular weight of the enzyme was calculated to be 35 kDa by using SDS-PAGE. It was determined that the purified enzyme can be used in the process of casein coagulation, the first step of cheese making

Başar, Enes Emre
The presence of a large number of actors in the retail sector in recent years has led to intense competition. For this reason, it is increasingly important to determine the factors that affect retailer store preferences of consumers. In this direction, it is seen that a lot of studies have been done in the field of marketing. It has been generally focused that in these studies, low price, distance / location, store atmosphere and image, product variety and quality. These studies, however, have not revealed how the products consumers are planning to purchase have an effect on retailer store preferences. The lead product concept expresses which product categories are important in the retail store preference and explains consumer purchasing processes, thus providing a different perspective on retailer store preference. In this respect, the current study has tried to determine which product category is the lead product and examined the effects of lead product retailer's store preference. Thus, it is aimed to fill an important gap in the literature. In the scope of the research, the obtained data via the survey method from 444 consumers aged 18 years and living in the central district of Erzurum were analyzed. Findings show that fruit-vegetable product category is the lead product due to it has the greatest influence on consumers' retail store preferences

Özkan, Ahmet
In all of the orders which are the institutions of Sufism the Hazrat Ali and Ahl al-Bayt are shown love and respect. In addition, the love of the Hazrat Ali and Ahl al-Bayt seen in the works of the Sunni Sufis has caused them to be perceived as Alawi-Bektashi from time to time. One of the most important of these Sufis is Eshrefoghlu Rumi, the founder of the Eşrafiyye branch of Kadiriyye order. Eşrefoğlu, who frequently mentioned the Hazrat Ali and Ahl al-Bayt, particularly in his book Tarikatname, has been described as Alawi-Bektashi due to his expressions by some. This article was written to put forth Sunni Sufis’ and especially Eshrefoghlu Rumi’s perception of the Hazrat Ali and Ahl al-Bayt and to evaluate their being regarded as Alawi-Bektashi due to his views. For this purpose, first the understanding of the Sunni Sufis regarding the Hazrat Ali and the Ahl al-Bayt was addressed, and then comparisons were made by mentioning perceptions of Eshrefoghlu Rumi in question. In particular, the place of the Hazrat Ali and Ahl al-Bayt in the understanding of Sunni Sufism was identified. As a result, it was observed that both Sunni Sufis’ and Eşrefoğlu Rumi’s perception of the Hazrat Ali and Ahl al-Bayt developed in Sunni Sufi culture and the love of the Hazrat Ali and Ahl-al Bayt was very intense particularly in the followers of the orders connected to the Prophet Muhammad through the Hazrat Ali’s descendants. One of the findings of the research was that this perception of the Sunni Sufis and Alawi-Bektashi and Shia communities showed similarities from time to time.

Yaman, Murat; Küçükşen, Murat
Local administrations are the institutions which meet the local needs in the location. Local administrations are linked to democracy in terms of the participations in local decision-making processes. In this sense, the existence of democratic is dependent upon the access to local participation. Today, methods of local participation are divided into two categories as means of traditional and new participation. For this reason, classical and new methods of participation need to be evaluated in detail. The process of democratisation in local administrations and the axe of globalisation and localisation both require a detailed examination on participation with an expectation of important roles of new methods and tools for local participation. Within this context, this paper aims to evaluate and highlight the importance of means for local participation in the process of democratisation in local administrations

Today, significant improvements are experienced in e-book and tablet computer technologies as in direct proportion to each other. These technologies are often found place for theirselves in educational environments. Positive developments in this direction are also experienced in our country. From this point of view, the use of existing technologies that are becoming increasingly widespread in learning environments and analysing of user opinions in depth is considered significant. Within the scope of this study, it was aimed to be determined the user opinions about the application of video texts developed for e-books prepared for tablet computers as lesson finalizer. In this context, design based research method was preferred within the scope of the study. The study group consists of 22 participants selected from approximately 800 first grade students enrolled in the Social Services Department of Atatürk University Faculty of Open University. However, after the first cycle, it was continued to study with a total of 20 participants, 11 boys and 9 girls because of that 2 of participants had left. Semi-structured interview forms from qualitative data collection tools were used as a data collection tool in the study. Content analysis method, which is an inductive method, was used in the analysis of the interviews with the participants. In the study, learners deem necessary that video texts in the summary part of the lesson should be used. However, the sort of video, the number of video used in the content and the scope of video are seen to be effective in the summary section of the using of video. The learners noted that the using of video texts in the summary section is effective in terms of repetition, persistency, summarization, completion of missing and supporting of learning. It is thought that the excessive using of video in the lecturing negatively affects the views on video use. In the e-books developed for tablets, while, the video type and number of videos are effective in the using of video texts as a lesson finalizer, it can be said that preparing short videos which briefly describe the summary of the lesson, highlight important points and make subsequent studies easier are important.

In research, the following data were determined that all marmalade samples' total and water soluble dry matter contents were over 55%; water activity and total sugar contents were over 0.79 and 47 g/100g and HMF contents were found between 10.95 and 1094.11 mg/kg. All samples contained gallic acid, catechin, epicatechin, vanillin, chlorogenic acid, caffeic acid, coumaric acid, p-coumaric acid, hesperidin, routine, ellagic acid and quercetin in different ratios. Phenolic substance values of marmalade samples were between 64.67-205.75 µg GAE/g. The highest DPPH radical scavenging activity belonged to the cornelian cherry marmalade (%3.72±0.09). Because of the high phenolic composition and antioxidant activities of rosehip, blackthorn, cornelian cherry and Ahlat pear marmalades besides their significant health benefits may be used for developing functional foods. High HMF contents in blackthorn and Ahlat pear marmalades could be due to long processing time and boiling process at high temperature during conventional production, and consumers should be aware of this problem.

Carbonic anhydrase enzyme plays a vital role in metabolic events such as acid-base regulation and respiration. Inour research, it is tried to determine the inhibitory influences of the cardiovascular therapeutics esmololhydrochloride, amiodarone hydrochloride and lidocaine hydrochloride on human erythrocytes carbonic anhydrases(hCA I and II). In accordance with this purpose, carbonic anhydrase isoenzymes were purified from humanerythrocytes by using affinity chromatography method. Enzyme purity was checked by SDS-PAGEelectrophoresis method. After the carbonic anhydrase enzymes were purified, the inhibitory affects ofcardiovascular therapeutics on these enzymes, using esterase activity, which is the method of measuring in vitroactivity, were examined. The three cardiovascular therapeutics dose-dependently decreased activity of hCAs. IC50values of amiodarone hydrochloride, esmolol hydrochloride and lidocaine hydrochloride were found to be,respectively, 0.91 mM, 5 mM, 5.8 mM for hCA-I and 0.41 mM, 3.5 mM, and 6.36 mM for hCA-II. Our resultsproved that, under in vitro conditions, cardiovascular therapeutics significantly inhibit human CA-I and IIactivities. So, irregular use of these medicines may cause serious adverse effects in terms of human health.

The effects of exercise at the anaerobic threshold on nesfatin-1 levels have been investigated in trained male subjects. A total of 30 males performed an aerobic running exercise for 30 min in mornings. Venous blood samples were taken at rest and at the end of the test. ELISA method was used to analyse nesfatin-1 levels. Nesfatin-1 levels were found to be 102.8±5.1 ng/ml at rest and it increased to 109.6±6.2 ng/ml at the end of the test. However, this increase was not statistically significant (P=0.3). The nesfatin-1 level was found to be 1.695±0.09 ng/ml/kg when standardised to body weight. There was a correlation between body weight to nesfatin-1 levels and change of nesfatin-1 levels during exercise: R=0.50858 (p=0.004). We showed that nesfatin-1 is not exercise induced hormone but it may vary among the subjects either increasing or decreasing. Thus further studies should be performed in subjects with carying fitness status.

The purpose of this study is to examine the educational sciences scientific publication performance of Turkey and G-20 countries relatively by using some bibliometric data. This study was designed as a case study. Study group composed of Turkey and other G-20 countries. Bibliometric variables for educational sciences were obtained from SCImago and Ulakbim databases. Data analysis was processed with document analysis technique. Findings show that the number of published documents has increased dramatically in most of the G-20 countries since 2012. That is the same case for citable documents variable. Turkey is in the upper level for those variables. As for cites and citation rates, the rank differs considerably. While Turkey is in a better place for the first three variables, its citation rate rank is far below the table. On the other hand, h-index and impact factor vary greatly among the countries and some specific countries attract more attention with their performance values. To sum up, Turkey, with its documents, citable documents and cites, has relatively better statistics than citation rate, h- index and impact factor. This shows that the success gained in quantitative variables does not reflect positively on qualitative ones.
