Bu çalışmada Türkiye ekonomisindeki 02.01.2013 ile 11.12.2018 dönemi günlük (5 işgünü) döviz kurlarındaki döngüler, periodogramlar yardımıyla belirlenmeye çalışılmıştır.Çalışmada günlük Türk lirası karşısında Dolar kapanış (Xt) ve Euro kapanış (Yt) değerleridikkate alınmıştır. Analizler sonucunda bu iki serinin de aynı periyodlarda hareket ettiğigözlenmiştir. Günlük döviz kurlarının durağanlığı standart birim kök testlerinin yanındaperiodogram tabanlı birim kök testi ile de sınanmış ve her iki serinin de birinci derecedenbütünleşik olduğu gözlenmiştir. Birinci derece fark serilerinde 4, 6 ve 7 günlük periyodlargözlenmiştir.

Natural gas and oil prices, which have an important place in the world energy markets, are among the fundamental inputs that are very important in terms of establishing sustainable economic policies. When these two input prices are analyzed cyclically, it is thought that any periodicity will be important in terms of economic policies and academic studies. These two input prices, which are important indicators of the industrial development levels of the countries, were investigated in the interactions and relations between each other. In this study, the periodic components of the monthly average gross oil and natural gas prices of the period 2004: 01-2018: 12 were investigated. The data in the study were compiled on the basis of monthly averages by compiling the prices in the international markets (end of day closing values as of 00:00). Data were obtained from Matriksdata data provider company by using a data terminal subscription. In addition to the standard unit root tests, the unit was tested with unit root tests based on periodograms and both series were not stable. Since both series are not stationary, first-order difference series are used for the determination of periodic components. While no periodic component was observed in natural gas prices, the prices of the crude oil prices were 36 months (three years), 60 months (five years), 45 months and 90 months. Although both series were integrated in the first degree, there was no long-term stable correlation between the two series. It can be said that these two series have different periodic structures.

In this study; the relationship between the professional motivation and job satisfaction levels of the administrative staff at Munzur University was evaluated together with the socio-demographic characteristics of the personnel. The distribution of the demographic characteristics (gender, age groups, marital status, personel cadre position and the total working time at the university) of the administrative staff participating in the survey were examined. It was also tested at 5% significance level whether the level of job satisfaction and professional motivation of the staff shows significant differences in terms of variables in the sociodemographic characteristics section, which is the first part of the questionnaire form. Similarly, the correlation between the job satisfaction of the staff and the level of professional motivation was also examined. The findings of the study indicate that there is a positive moderate correlation between job satisfaction levels and professional motivation levels. While socio-demographic characteristics indicated that job satisfaction and vocational motivation (total) levels were significantly different by age group, the total working times at university had an effect on job satisfaction.Finally, there was an effect on gender's professional motivation (external) levels, professional motivation (internal-total) differs in terms of personnel cadre positions.

Ekonometri ve zaman serileri alanında popüler birkonu durağan olmayan zaman serileri arasındaki eş- bütünleşme ilişkileridir. Engle-Granger in En KüçükKareler Metodu ve Johansen in Koşullu MaksimumOlabilirlik Metodu değişkenler arasındaki ilişkileri be- lirlemek için en yaygın kullanılan metodlardır. Ayrıcaperiodogram ordinatlarına dayanan bir birim kökütest etmek için önerilen metod, geleneksel testlere görebelli avantajlara sahiptir. Periodogramlar herhangi birmodel tanımlaması olmaksızın tanımlanabilmektedirve bir birim kök varlığı altında kesin dağılımı elde edile- bilmektedir. Daha yüksek dereceli süreçler için dağılımasimptotik olarak aynı kalmaktadır. Ayrıca son yıllar- da, bir çok gelişmekte olan ülke, ekonomik büyümeninönemli bir bölümü olarak turizm endüstrisinin gelişi- mine öncelik vermektedir. Bu bağlamda, turizme da- yalı büyüme hipotezi ekonomistler ve politika yapıcılararasında büyük ilgi çekmektedir. Bu nedenle çalışma- da, periodograma dayalı testin geleneksel testlere göreavantajını göstermek için, Türkiye de 1999:01-2010:12dönemi için turizm ve ekonomik büyüme arasındakiolası ilişki, Periodogram Metodu, Johansen MaksimumOlabilirlik Metodu ve Engle-Granger Metodu ile ince- lenmektedir

The climate that has a dynamic structure varies continuously. Basic climatological features of any region depend on many meteorological variables, such as precipitation and temperature records. The changes in these two variables reveal important clues about climate variations. Turkey is one of the sensitive areas for climate variation around the world. In this study, statistical analysis is applied to historical data set consisted of monthly precipitation totals (mm.) which are provided by the Turkish State Meteorological Service(TSMS) for 1999-2010 period in Turkey. Furthermore, a sinusoidal model for each region obtained by using a time series method is proposed in order to obtain a sinusoidal form for the precipitation to each region. Besides a basic form of Frequency Domain Techniques, usual Box-Jenkins ARIMA approach is applied in this study. In conclusion, it is observed that the sinusoidal model predictions are more appropriate than ARIMA techniques and usual generalized linear model (GLM) techniques.
