Data mining is the task of accessing useful information from a large capacity of data. It can also be referred to as searching for correlations that can provide clues about the future in large data warehouses by using computer algorithms. It has been used in the tourism field for marketing, analysis, and business improvement purposes. This study aims to analyze the tourist profile in Turkey through data mining methods. The reason relies behind the selection of Turkey is the fact that Turkey welcomes millions of tourist every year which can be a role model for other touristic countries. In this study, an anonymous and large-scale data set was used under the law on the protection of personal data. The dataset was taken from a leading tourism company that is still active in Turkey. By using the k-means clustering algorithm on this data, key parameters of profiles were obtained and people were clustered into groups according to their characteristics. According to the outcomes, distinguishing characteristics are gathered under three main titles. These are the age of the tourists, the frequency of their vacations and the period between the reservation and the vacation itself. The results obtained show that the frequency of tourist vacations, the time between bookings and vacations, and age are the most important and characteristic parameters for a tourist's profile. Finally, planning future investments, events and campaign packages can make tourism companies more competitive and improve quality of service. For both businesses and tourists, it is advantageous to prepare individual events and offers for the three major groups of tourists.

Mule Bone (1931), Zora Neale Hurston's collaboration with Langston Hughes, has been credited as the 'first' attempted by African Americans to create black folk comedy. The proposed research is driven from a question to the recent scholarship's tacit consent on such historic importance imposed on the play. This paper suggests a possibility that De Turkey and De Law (1930), Hurston's edition of the collaboration work, could be the truly first attempt in the tradition of American black folk comedy. By illuminating a series of historical moments in which Hurston first expressed her dream for writing a real black folk comedy that would be a really new departure in the African American drama, then collaborated with Hughes on the dream play project, and eventually quit the collaborationship due to artistic dispute with Hughes, this paper explains why Hughes edition Mule Bone came to remain 'unfinished' and, more importantly, fall short of Hurston's original goal and expectation from the collaboration. On the other hand, this paper sheds light on the significance of often-ignored Hurston's edition De Turkey and De Law by demonstrating how this play, compared to Mule Bone, fulfills her original idea of black folk comedy in terms of contents and themes compared with Mule Bone. Adding to the knowledge about little known behind story related to the Mule Bone controversy and the subsequent birth of the two different editions of the Hurston-Hushes collaboration project, supplementing the dearth of the related research with a critical comparison of the two editions, and discussing the validity of Hurston's edition as the real sense of black folk comedy, this paper argues for the necessity of reconsidering the origin of the mentioned genre. This paper finally concludes that De Turkey and De Law, replacing Mule Bone, deserves a right to be truly the first American black folk comedy genre in the sense that it was completed and copyrighted three months earlier than Mule Bone and that, more importantly, it cherished the original aim and artistic vision of black folk comedy Hurston first planned and expected through the collaboration with Hughes.

A computer-assisted desktop is developed for layout design of a concrete gravity dam on the basis of safety and economy. Using a set of regression equations, a dam layout is proposed. With reference to the regression equations and relevant input data, overall dam dimensions are determined by satisfying the stability criteria jointly under usual, unusual, and extreme loading conditions with the desired hydraulic conformity. Among several feasible alternatives, the program enables a designer to select the optimum layout, which corresponds to the minimum total cost of the structure. The method is applied to a case study to examine dimensions of proposed alternatives and to compare them with those of an existing dam.

Being one of the most important textile and apparel producers for years, Turkey began to become active in terms of retailing. Although retailing industry is in its growing phase, the social and economic influences caused the customers' tastes and demands to be more distinctive and segmented in parallel with the advancement of the retail industry. Therefore, the retail industry began to develop in more fragmented way where clear boundaries between different types of retailers were established. In this study, the apparel retail market is overviewed and analyzed within the context for determination of the current situation and future prospective. To this aim, the textile and apparel companies that are active in Turkey were classified into groups based on the type of distribution channels they used. Then, the performances of the groups were established using the secondary type of resources. Finally, the findings were summarized, by showing the similarities and differences between different channels.

The concern about the possibility of food can be a vehicle for the transmission of Clostridium difficile to humans has been raised recently due to the similarities among the strains isolated from patients, foods and food animals. In this study, therefore, the prevalence of C. difficile was investigated in beef and chicken meat products collected from 57 different butcher shops, markets and fast food restaurants in Sakarya province of Turkey. Two out of 101 samples (1.98%) was positive for C. difficile indicating a very low prevalence. The pathogen was isolated from an uncooked meatball sample and a cooked meat $d{\ddot{o}}ner$ sample, whereas not detected in chicken meat samples. The meatball isolate was resistant to vancomycin and tetracycline, while the cooked meat $d{\ddot{o}}ner$ isolate was resistant to vancomycin and metronidazole. Both isolates were sensitive to moxifloxacin and clindamycin. Toxins A and B were not detected. This study reveals the presence of C. difficile in further processed beef products in Turkey.

Teachers' attitudes and beliefs are related to teaching practices and are dependent upon their teaching domain. The present study compares conceptual models of creative student oriented teaching practices of mathematics teachers in two OECD countries, South Korea and Turkey to provide an insight for teacher educators and policy makers. Teaching and Learning International Survey 2008 (TALIS 2008) data are used to test the fit of a path analysis model with a subsample of l337 middle school mathematics teachers ($N_{Korea}$ = 562 vs. $N_{Turkey}$ = 775). The study showed that Turkish teachers were younger and less experienced, whereas Korean teachers were better educated. Despite the statistical differences in attitudes, beliefs and practices between countries, it was found that the teaching practices of mathematics teachers in both countries were more complex than to be explained only through attitudes and beliefs.

Depending on the increased energy needs, a large number of dams have been built around the world. These dams have significant impacts on river ecology and climate change. When the climate change scenarios are examined, it is stated that the annual average temperature in Turkey will increase by 2.5-4 degrees in the future years, the south of the country will be opposed to the severe drought threat, and the northern regions will have a flood risk. In particular, it can be predicted that many dams and dam lakes built in the North of Turkey may increase the impact of climate change. In this study, the effects of the dams constructed in Çoruh basin on climate change are examined. Environmental and ecological problems of dam reservoirs have been examined. As a result of the data received from meteorological stations, it was determined that temperature and rainfall changes in the region. In this direction, solution proposal is presented.

House dust mites play an important role in the pathogenesis of allergic diseases. Many factors may influence mite growth. The presence of mites is related to mean temperature and humidity as well as altitude. The aim of this study was to analyze the mite fauna in 5 regions of western Anatolia, Turkey, that have similar climatic properties with low mean temperature and humidity, but differ in altitude. During the period October-November 2004, house dust was collected from 290 homes in 5 different cities. House dust mites were isolated in 67 (23.1 %) of 290 samples. The family Pyroglyphidae (Astigmata) was present in all positive samples. This study suggests that the selected western Anatolian regions that share similar environmental conditions host similar dust mite populations.
