DETERMINATION OF INDIVIDUALS' QUALITY OF LIFE AND EXERCISE HEALTH BELIEF LEVELS
No full textThe aim of this research is to determine the quality of life and exercise health belief levels of individuals residing in Sakarya and to determine the differentiation status of quality of life and exercise health belief levels according to their demographic characteristics. The sample of the study consists of 349 people selected by simple random sampling method from these participants. Personal Information Form, The Health Belief Model Scale for Exercise (HBMS E) and World Health Organization Quality of Life Scale- Short Form were used as data collection tools. In the analysis of the data, the t-test for pairwise comparisons and the One Way Anova Test for multiple comparisons were applied to examine the differences between the variables. It was determined that the general averages of the participants' exercise health belief scale did not differ according to variables such as gender, marital status, regular exercise, age and income levels (p<0.005). A statistically significant difference was found between the general averages of the quality of life scale and the age variable (p<0.05). It was determined that there was a statistically significant difference between the general averages and all sub dimensions of the exercise health belief scale and the education variable (p<0.05). As a result, it has been determined that the educational status of the individuals participating in the research has a positive effect on their exercise health belief levels. As the age of individuals increases, it has been thought that it is an important determining factor in their quality of life
The Relationship between Recreation Awareness and Happiness Levels of Children in Turkey
No full textBackground. It is known that recreational awareness and physical activities are essential in increasing society's happiness. Objectives: This study aims to determine the relationship between the recreational awareness levels and happiness levels of children between the ages of 14-20, determine whether demographic variables affect recreational awareness levels, and examine the relationship between them. Methods. The study sample consists of 448 children (16.04 +/- 2.79), 272 males and 176 females, residing in two regions in Turkey. As a data collection tool in the research, The recreation Awareness Scale (RFS) and Oxford Happiness Scale were used. Pearson correlation, independent sample t-test, and one-way analysis of variance (ANOVA) were used to analyze the data. Quantitative research methods it is a research conducted with a relational screening model. Results. It was determined that the recreational awareness levels of the participants and social success, self-development, and pleasure-entertainment sub-dimensions were high, and their happiness levels were moderate. There was no significant difference between the recreation awareness sub-dimensions of the children participating in the study and the gender variable. There were statistically significant differences in pleasure-fun (P=0.001), social success (P=0.000), and self-development (P=0.000) in all sub-dimensions according to the living area variable. While there was no difference in the self-improvement (P=0.188) sub-dimension of the recreational awareness scale according to the monthly income variable, significant differences were found in the social-achievement (P=0.017) and pleasure-entertainment (P=0.015) sub-dimensions. As a result of the Pearson correlation analysis, it was determined that there was a weak positive correlation between the recreational awareness levels of the participants and their happiness levels (r= .610, P> 0.24). Conclusion. As a result of the analysis made between the recreation awareness levels of the children participating in the research, the recreation awareness levels of children in the age group participating in the research can be increased, and their happiness levels can be directly affected
Application of cellular neural network (CNN) to the prediction of missing air pollutant data
No full textBayat, Cuma (Arel Author)For air-quality assessments in most major urban centers, air pollutants are monitored using continuous samplers. Sometimes data are not collected due to equipment failure or during equipment calibration. In this paper, we predict daily air pollutant concentrations (PM(10) and SO(2)) from the Yenibosna and Umraniye air pollution measurement stations in Istanbul for times at which pollution data was not recorded. We predicted these pollutant concentrations using the CNN model with meteorological parameters, estimating missing daily pollutant concentrations for two data sets from 2002 to 2003. These data sets had 50 and 20% of data missing. The results of the CNN model predictions are compared with the results of a multi-variate linear regression (LR). Results show that the correlation between predicted and observed data was higher for all pollutants using the CNN model (0.54-0.87). The CNN model predicted SO(2) concentrations better than PM(10) concentrations. Another interesting result is that winter concentrations of all pollutants were predicted better than summer concentrations. Experiments showed that accurate predictions of missing air pollutant concentrations are possible using the new approach contained in the CNN model. We therefore proposed a new approach to model air-pollution monitoring problem using CNN. (C) 2011 Elsevier B.V. All rights reserved
Assessment of particulate matter in the urban atmosphere: size distribution, metal composition and source characterization using principal component analysis
No full text#nofulltext# --- Bayat, Cuma (Arel Author)In this study, the size distribution of airborne particles and related heavy metals Co, Cd, Sn, Cu, Ni, Cr, Pb and V in two urban areas in Istanbul: Yenibosna and Goztepe, were examined. The different inhalable particles were collected by using a cascade impactor in eight size fractions (9 µm) for six months at each station. Samples were collected on glass fiber filters and filters were extracted and analyzed using ICP-MS. Log-normal distributions showed that the particles collected at the Yenibosna site have a smaller size compared to the Goztepe samples and the size distribution of PM was represented the best by the tri-modal. The average total particle concentrations and standard deviations were obtained as 67.7 ± 17.0 µg m-3 and 82.1 ± 21.2 µg m-3, at the Yenibosna and Göztepe sites, respectively. The higher metal rate in fine and medium coarse PM showed that the anthropogenic sources were the most significant pollutant source. Principal component analysis identified five components for PM namely traffic, road dust, coal and fuel oil combustion, and industrial

A new approach to prediction of SO2 and PM10 concentrations in Istanbul, Turkey: Cellular Neural Network (CNN)
No full textBayat, Cuma (Arel Author)This article describes the application of a cellular neural network (CNN) to model air pollutants. In this study, forthcoming daily and hourly values of particulate matter (PM10) and sulphur dioxide (SO2) were predicted. These air pollutant concentrations were measured at four different locations (Yenibosna, Sarachane, Umraniye and Kadikoy) in Istanbul between 2002 and 2003. Eight different meteorological parameters (temperature, wind speed and direction, humidity, pressure, sunshine, cloudiness, rainfall) recorded at Florya and Goztepe meteorological stations were used to model inputs. First, the results of CNN prediction and statistical persistence method (PER) were compared. Then, CNN and PER outputs were correlated with real time values by using statistical performance indices. The indices of agreement (d) for daily mean concentrations were found using CNN and PER prediction models: 0.71-0.80 and 0.71-0.78 for PM10, and 0.81-0.84 and 0.77-0.82 for SO2 in all air quality measurement stations, respectively. From these values, CNN prediction model are concluded to be more accurate than PER, which is used for comparison. In hourly prediction of mean concentrations with CNN, d value is found as 0.78 and 0.92 for PM10 and SO2, respectively. Thus, it was concluded that CNN-based approaches could be promising for air pollutant prediction
Postmodern Features in Christoph Ransmayr's Novel "The Last World" (Die Letzte Welt)
No full textBu çalışma, Avusturyalı yazar Christoph Ransmayr’ın (1954-) 1988 yılında yayınlanan “Son
Dünya” (Die letzte Welt) adlı romanının postmodern bağlamda incelenmesini hedeflemektedir.
Roman içerisinde bulunan postmodernizmi yansıtan unsurlar, çoğulcul yöntem kullanılarak açığa
çıkarılmıştır.
“Son Dünya” romanı, antik Yunan şairi Publius Ovidius Naso tarafından, M.S. 2-7.
yüzyıllarda kaleme alınan “Dönüşümler” (Metamorphoses) romanının bir reprodüksiyonudur.
Hikâye, Naso’nun sürgüne gönderildiği Karadeniz’deki bir liman kenti olan Tomi’ye ve onu
bulmak için geri dönüşü olmayan bir yolculuğa çıkan Cotta’nın yaşadığı gerçek üstü olaylara
odaklanmaktadır.
"Son Dünya" romanının merkezinde, Naso'nun "Karadenizden Mektuplar"ında yer alan
alıntılarla şekillendirilen baş karakter Cotta yer almaktadır. Diğer karakterler ise Naso'nun efsanevi
eseri "Dönüşümler"den ilham alınarak yaratılmıştır. Bu eser, antik Roma'nın siyasi, idari ve hukuki
yapısı üzerinden günümüz konularını eleştirerek, Naso'nun “Dönüşümler”inden meydana getirilen
apokaliptik ve aynı zamanda fantastik bir dünyanın kesitlerini anlatmaktadır.
Çalışmanın devamında postmodernizm hakkında bilgi verildikten sonra, Ransmayr ve “Son
Dünya” hakkında bilgi verilmektedir. Ayrıca, romanın çeşitli postmodern özelliklerini yansıttığı,
çoğulculuk (Pluralität), metinlerarasılık (Intertextualität), üstkurmaca (Metafiktion), apokaliptik
(Apokalypse), mit-mitoloji (Mythos-Mythologie), büyülü gerçeklik (Magischer Realismus) gibi
unsurların nasıl ele alındığı açıklanmaya çalışılmıştır.This study aims to examine the novel "The Last World" (Die letzte Welt) by Austrian author
Christoph Ransmayr (1954-) in the context of postmodernism. The elements reflecting postmodernism
within the novel are revealed through the implementation of a pluralistic approach..
"The Last World" is a reproduction of the ancient Greek poet Publius Ovidius Naso's
"Metamorphoses," written between the 2nd and 7th centuries A.D. The story centers around Tomi, a
harbor town in the Black Sea where Naso is exiled, and the surreal events experienced by Cotta, who
embarks on an irreversible journey to find him.
At the heart of the novel "The Last World" lies the protagonist Cotta, shaped through quotations
from Naso's "Letters from the Black Sea." Other characters are inspired by Naso's legendary work
"Metamorphoses." This literary piece critically examines contemporary issues through the lens of
ancient Rome's political, administrative, and legal structure. It weaves together apocalyptic and
fantastical elements derived from Naso's "Metamorphoses," offering glimpses into a world both
extraordinary and surreal.
In the continuation of the study, after providing information about postmodernism, details about
Ransmayr and "The Last World" are given. Additionally, it is attempted to explain how the novel
reflects various postmodern features such as pluralism (Pluralität), intertextuality (Intertextualität),
metafiction (Metafiktion), apocalypticism (Apokalypse), myth-mythology (Mythos-Mythologie), and
magical realism (Magischer Realismus)

Knowledge levels and preference reasons regarding the doping of U23 Turkish National Team athletes
No full textThe aim of this study was to determine the knowledge level and preference reasons of U23 Turkish National Team athletes about doping. The sample of the study was created by 100 U23 Turkish National Team athletes from different branches. 5-points likert-type scale and a questionnaire consisting of 29 questions was applied to the athletes. In the analysis of the obtained data, descriptive statistics (percentage and frequency) and chi-square test were used. As a result, it was determined that 47% of athletes had enough knowledge about doping, and 81% of them knew that doping had great damages on health, but they were indecisive about the usage of doping. Although athletes tend to use doping, this result may be due to the risk of being caught by the World Anti-Doping Agency
The novel "Tyll" by Daniel Kehlmann in the context of postmodern fiction
No full textAvusturyalı-Alman yazar Daniel Kehlmann'ın 2017 yılında yayınlan en son eseri Tyll'in incelendiği bu çalışmada metne bağlı inceleme yöntemi olmak üzere çoğulcu araştırma metoduyla postmodern söylem özelliklerinin analizi amaçlanmakadır. Tyll, Otuz Yıl Savaşı ve Barok dönemden bir hikâyedir. Aynı zamanda eserin başkarakteri olan Tyll, eserde bütün öykülerde yer alan bir figürdür. Fakat eser ünlü hokkabaz hakkında yazılmış bir eser değildir. Kehlmann efsanevi Orta Çağ figürü ünlü hokkabaz Till ya da Thyl Eulenspiegel'i Otuz Yıl Savaşının Almanya'sına yerleştirerek Avrupanın siyasi ve entelektüel topoğrafyasını kararlı bir şekilde şekillendiren bir döneme hareket etmektedir. Bunu yaparken de Barok dönemi bir kahraman için tipik olan Tyll'e benzersiz nitelikler eklemekte ve sanatsal olarak iç içe geçmiş bir dünya canlandırmaktadır. İlk olarak bu çalışmada tez başlığında yer alan Tyll eseri ve yazarı Daniel Kehlmann ile igili bugüne kadar yapılan lisansüstü çalışmalar ile ülkemiz akademisyenlerinin makale ve bildirileri hakkında bilgiler verilmektedir. Daha sonra analizin yürütülmesi için gerekli olan teorik temeller aktarılmakta ve bu çalışma ile ilişkileri sunulmaktadır. Sunulan teoriler daha fazla içeriğe sahip olsalar da, kaynakların kendilerine atıfta bulunularak yalnızca analiz için yararlı olan yönler vurgulanmaktadır. Bu teorik bilgilere yardımcı olması adına Kehlmann'ın konuyla ilgili yaptığı açıklamalar da kullanılmaktadır. Postmodern edebiyat özelliklerine göre incelediğimiz çalışmada yazar Kehlmann ve eseri Tyll hakkında detaylı bir bilgi verildikten sonra çalışma, hangi satırların "üstkurmaca", "metinlerarasılık", "eklektiktizm", "kitsch", "çoğulculuk", "yeni çağ", postmodern gerilim/gizem" ve "postmodern kimlik" özelliklerini yansıttığı göstererek devam etmektedir. Daha sonra Tyll'den alıntılar kullanılarak yapılan tespitler ve analizler, teorik çerçevede ele alınan tezlere dayanarak yorumlanmaktadır. Sadece ilgili bölümler ele alındığından eserin bazı bölümleri analize dâhil edilmemiştir. Son olarak, analizi yapılan postmodern söylem özelliklerinin ve esere yansımasının genel bir değerlendirmesini ve bununla ilgili çıkarımları içeren "Sonuç" bölümü sunulmaktadır.In this study, where Austrian-German writer Daniel Kehlmann's latest work Tyll, which was published in 2017, is analyzed, is aimed to examine postmodern discourse features through textual analysis. Tyll is a story from the Thirty Years War and Baroque era. Tyll is a figure in all stories in the novel, but it is not a novel written about the famous juggler. Kehlmann bring the legendary, famous Medieval figure famous juggler Till or Thyl Eulenspiegel to Germany's Thirty Years War, which is a period that decisively shapes the political and intellectual topography of Europe. In doing so, he adds unique qualities to Tyll, typical of a Barock hero, and portrays an artistically intertwined world. Firstly, information about the novel Tyll and its autor Daniel Kehlmann, and post-graduate studies and articles of Turkey academicians are given. Then, the theoretical foundations required for conducting the analysis are introduced and their relations with this study are presented. Although the theories presented have more content, reference is made to the resources themselves, emphasized only those aspects that are useful for analysis. To help with this theoretical information, Kehlmann's explanations on these topics are also used. The study we examined according to the postmodern literary features, after gived detailed information about the author Kehlmann and his work Tyll, continues by showing, which lines reflect "metafiction", "intertextuality", "eclecticism", "kitsch", "pluralism", "new age", postmodern tension / mystery " and "postmodern identity". Then, the determinations and analyzes using quotes from Tyll are interpreted based on the theses dealt with in the theoretical framework. Some parts of the novel are not included in the analysis since only the relevant sections is handled with. Finally, the "Conclusion" section, which includes a general evaluation of the analyzed postmodern discourse features and its reflection on the work, is presented
