Saylan, Kemal
The Ottoman Empire, gave importance managing and running mines in its own territories from its foundation period. The Empire which took advantage of experience of the conquered regions improved mining industry to the competitive level with Europe in the 15th and 16th centuries. But the Empire was not able to keep pace with developments since 18th century and fell behind with the industry. It consequently took some steps to stimulate the sector. So that, many native's businessmen of Muslim and non-Muslim aspired that to mines in Licese, but they could not manage a stable. In this period, European companies applied for the Licese mine in the sanjak of Karahisar-i Sarki, as well as the other mines in Anatolia. The most important of these companies is British Asia Minor Mining Company. After Asia Minor Mining Company had purchased the mine in Licese, economy of region revived. Activities of company have changed patterns of work in the region. The inhabitants who previously engaged in farming began to receive a sallary as provision of effort. However, the activities of company in the region caused to security and political problems. In this work, we deal with the status the mines in Licese and the economic, social and political effects of the mining activities of Asia Minor Mining Company in the region.

Sentürk, Suat Hayri
Having the largest share of public revenues tax has a vital importance in terms of state. Today, main purpose of the tax administration constitutes to obtain high tax revenues with low administrative costs, in many countries. In the same way, voluntary tax complince for the tax authorities is an important issue. Increasing degree of voluntary tax compliance will increase tax revenues. Voluntary tax compliance is an acceptable accurate reporting of tax liability by the taxpayers. The aim of this study is to examine the relationship between voluntary tax compliance and benefit principle of taxation. Benefit principle of taxation states that taxes should be based on benefits received from public goods. Benefit principle of taxation will increase voluntary tax compliance.

Top, Yener; Adanur, Hakan; Öz, Mehmet; Yasar, Mehmet
In total, 95% of all business enterprises established in Turkey are micro-scale, and this figure increases to 98.6% in the forest products industry. Micro-scale enterprises are important in terms of production, employment, and overcoming economic imbalances among regions. The forest products industry, which includes three subdivisions within the manufacturing sector, occupies an important place in the overall Turkish manufacturing sector. Thus, this study examined the structural characteristics of forest product enterprises in Gumushane Province. The research involved in-person interviews with personnel at 47 enterprises. The data revealed that the sawmill division was especially important with respect to the use of local poplar logs. The sawmill and furniture divisions accounted for 28% of all enterprises and 26% of all employees in the manufacturing sector in Gumushane. We found that 57% of enterprises had difficulty in finding working capital and 55% of enterprises experienced shortages of labour. The average contribution of each forest products business to employment (2.55) was more than that of other manufacturers in Gumushane (2.27). The forest product businesses in Gumushane resemble other micro-scale enterprises located in other regions of Turkey in terms of their structural properties.

Dogan, Caglayan; Cubukcu, F
Some Explicit Polaroids is one of the most sensational plays reflects consumerist culture of 2000s twentysometings is described as controversial. Some Explicit Polaroids is a political criticism on the confrontation of the two generations and reflects consumerist tenets, which hold values of globalisation. This study tries to prove that Ravenhill's work is totally reflection of the logic of consumerism and post-consumerism in terms of contemporary British society that is subjected to contemporary plays mostly. This study particularly unveils the perception of consumerist culture that is embodied within the scope of Ravenhill's perspective on British society; therefore, it aims to shed some light the globalised and cruelly capitalised world. The beginning of this study discusses the ongoing understanding of theatre and its representative perspectives after nasty nineties, as well as the social, economic, and political processes that led to the arrival of In-Yer-Face Theatre. Additionally, Mark Ravenhill's theatre aesthetic and his contributions towards contemporary British Theatre are briefly revealed. In this study, the evaluations written on consumerism and globalization are dealt with according to their resonances in the play. (C) 2015 The Authors. Published by Elsevier Ltd.

Dogru, Bulent
This study analyzes the nonstationarity of per capita real GDP for 11 Middle East and North Africa (MENA) Countries over the period 1970 to 2012 using two recently developed methods. SURADF and CADF panel unit root tests allowing for cross sectional dependence are used to determine whether output fluctuations are permanent or transitory. Contrary to the traditional view of business cycle, we find econometric evidence supporting the idea that the output fluctuations in MENA region are mostly permanent. These results also emphasize that the effectiveness of stabilization policies aimed at real output by the government should be reviewed to achieve longlasting results.

Dogru, Bulent
In this study it is analyzed whether there is a cause-and-effect relationship between inflation and budget deficit in Turkey with the annual data covering the time period between 19782002 when inflation was high and chronic. Econometric methods used in the study is based on the Johansen co-integration analysis and Granger causality connected error correction model. Empirical results suggest that in the longrun budget deficit and inflation is co-integrated, while budget deficit is Granger cause of inflation in short-run. However, inflation is not Granger cause of budget deficit. In other wordse causality is unilateral. The research also found that, response of inflation to a percentage increase in budget deficit is greater than ten percent in short-run.

Öztürk, Serkan
Many practical problems encountered in quantitative oriented disciplines entail finding the best approximate solution to an over determined system of linear equations. In this study, it is investigated the usage of different regression methods as a theoretical, practical and correct estimation tool in order to obtain the best empirical relationship between surface wave magnitude and rupture length for Turkey earthquakes. For this purpose, a detailed comparison is made among four different regression norms: (1) Least Squares, (2) Least Sum of Absolute Deviations, (3) Total Least Squares or Orthogonal and, (4) Robust Regressions. In order to assess the quality of the fit in a linear regression and to select the best empirical relationship for data sets, the correlation coefficient as a quite simple and very practicable tool is used. A list of all earthquakes where the surface wave magnitude (Ms) and surface rupture length (L) are available is compiled. In order to estimate the empirical relationships between these parameters for Turkey earthquakes, loglinear fit is used and following equations are derived from different norms: Ms = 1.02* LogL + 5.18, for L-2 Norm regression (R-2=0.71), Ms = 1.15* LogL + 4.98, for L-1 Norm regression (R-2=0.92), Ms = 1.04* LogL + 5.15, for Robust regression (R-2=0.75), Ms = 1.25* LogL + 4.86, for Orthogonal regression (R-2=0.68), Consequently, the empirical equation given by the Least Sum of Absolute Deviations regression as Ms = 1.15* LogL + 4.98 with a strong correlation coefficient (R-2=0.92) can be thought as more suitable and more reliable for Turkey earthquakes. Also, local differences in rupture length for a given magnitude can be interpreted in terms of local variation in geologic and seismic efficiencies. Furthermore, this result suggests that seismic efficiency in a region is dependent on rupture length or magnitude.

Deliser, Bilal
One of the dominant subjects of Quranic sciences, Muteshabihu'l Quran is presented in a different approach and classification in this study. The approach contains a classification which will help us to see unity. The data having no practical value and not helping us understand Quran or use related information in terms of methodology will not take place in the classification while muteshabihat (ambiguity) and some new information will be involved. On the other hand, this triple classification is a practical one which will help us put historical information and discussions into place. In the classification, Muteshabihu'l Quran will be analyzed under three main titles as follow: 1. Literal similarity, 2. Muteshabihat (ambiguity) discussed within the context of the verse 3/7 in Al-i Imran (Surah), and 3. Muteshabihat formed within the scope of the attributes of Allah. In the study, some overlooked approaches will be brought to the attention of readers, and some efforts will be made for linguistic, historical and socio-cultural understanding of the subject.

Yilmaz, Ozgur
The French Revolution and the invasion of Egypt created a crisis period in Ottoman-French relations and also arrested the French initiatives to trade in the Black Sea from the 17th century. However, on 25 July 1802 with the Treaty of Paris, the French were also given the right to trade in the Black Sea. In this way, France added the Black Sea to his privileges. With the 2nd and 3rd articles of the treaty, France has obtained the right to create consular agents on various points of the Black Sea. In this context, by a decision of 21 September 1802, a general consulate in Sinop and two consular agents in Trabzon and Eregli, depended to consulate general of Sinop, established. Pascal Fourcade was appointed as consul to Sinop and arrived to the city in the October of 1803. Fourcade was welcomed in a good way in Sinop; but the anarchy reigned in Anatolia after the Tayyar Pasha's exile, and intrigues of Russian colleague, Konuchenco, Fourcade stayed in difficult situations in the city. In fact, the preference of Sinop, as a general consulate centre was not in accordance with the terms of the period. Although Sinop had one of the best ports of the Southern Black Sea, the city was not as active as in the past on a commercial basis. It is known that Sinop was one of the places that mostly affected by Ottoman-Russian wars. Sinop had profited commercial relation that took place between the north-south ports of the Black Sea under the Ottoman dominance over the Black Sea. Especially in trade with Crimea, Sinop was the main port for Anatolian products. However, ever-expanding dominance of the Russia over the Black Sea, not only affected commercial relations between Black Sea ports but also started a decline period for southern Black Sea ports as Sinop and Trabzon that had strong commercial affairs with northern Black Sea. In this state Sinop was a small coastal town in the beginning of 19th century. But as the French consul stated, Sinop would became a strategic position as a port for trade of Anatolia and Iran in case of favourable conditions. Fourcade had very high expectations for the future of the city. The most important task of French consul was to achieve new markets for French goods; receive raw materials coming from Iran and Anatolia and establish warehouses for goods in Sinop. In this regard, Fourcade was describing the city as a trading port that had a very bright future and comparing the city to Alexandria and Baghdad, and also trying to show that Sinop was better port than Samsun and Trabzon. Fourcade's these expectations were not only connected to the creation of favourable conditions for trade and establishment of the necessary infrastructure. In fact, the realization of these plans depended on Tayyar Pasha's power, the governor of southern Black Sea region. As Fourcade's words, the main purpose of the consul was to establish good relations with Tayyar Pasa and convince him to gains of future French trade in his region. In the spring of 1804, Fourcade met with Tayyar Pasha and achieved positive results for his future plans; but because of obstructions of Russian consul in Sinop Fourcade did not realize his plans that emerged after the consul and Tayyar Pasa's interview in Bafra. Moreover defeat of Tayyar Pasha by Yusuf Pasha and exile to Sohum in 1805 created a real period of solitude for Fourcade in Sinop. Fourcade was met in early days in Sinop with Russian jealousy. When he arrived to Sinop, the city had been hosting Russian consuls since 1785. So, the biggest obstacle to plans of French consul was the Russian colleague Konuchenco. As the agent of Russia who did not want another European power in Black Sea, Konuchenco showed all his effort to fail Fourcade's mission in Sinop. In this context it is difficult to say that French Foreign Ministry predicted Russian rivalry in the Black Sea ports. Whereas with the Treaty of Kucuk Kaynarca, Russian had gained to right to trade in Black Sea and soon after the treaty they established a consular network in the port cities. Sinop was one the port cities that the Russian preferred to create a consular agent. Russian consuls in Sinop were so powerful that they could change kadi of Sinop. There were also very strong relations between Russian consul Konuchenco and Tayyar Pasa who had territories in Crimea consigned to Battal Huseyin Pasa, father of Tayyar Pasa, in his exile in Russia. In the first two years of consulate, Fourcade complained so often the relations between Tayyar Pasa and Konuchenco and Russian dominance over the Sublime Porte that seen in Sinop. Indeed, until the expulsion of Russian consul in February 1807, a diplomatic war had taken place in Sinop. Both consuls followed each other tightly and try to stop each other's activities. In this way, in the early years of the 19th century Sinop lived a provincial diplomacy period that created by presence of French and Russian consuls in the city. After the Tayyar Pasha's exile to Sohum, all the balance in Anatolia had changed. In the period of Tayyar Pasa's reign in the region, Fourcade had only to try to establish good relation with Tayyar Pasa for French trade; but after 1805, Fourcade rested between a multiple powers in Sinop. In this state the turmoil reigned in Anatolia after the Tayyar Pasha's exile was a real obstacle for Fourcade's plans. Furthermore the consulate was attacked by Greek sailor under the Russian protection in 1806 when Fourcade was in Kastamonu. But aggression of 1807 was more drastic for French consulate in Sinop. Fourcade and chancellor of consulate, Bernage, were injured by Laz sailors who participated the turmoil ended Selim III' reign, debarked in Sinop in way of their homeland. The expulsion of Russian consul Konuchenco from Sinop by Ottoman-Russian War broke out in 1806 was really created a liberty atmosphere in the city. But Russian-French rapprochement and the Treaty of Tilsit reversed this atmosphere against to French in Anatolia. These new conditions that clearly seen in aggression of 1807, showed also the future of the Fourcade's mission in Sinop. Although Fourcade's Sinop consulate did not obtain significant result for French trade; his six-year consulate left us very valuable documents that exist in French foreign ministry archives in Paris and Nantes. These consular reports and detailed travel voyages accounts are very valuable sources for Southern Black Sea region at beginning of the 19th century. Fourcade, like an archaeologist and geographer travelled in his consular district and prepared detailed reports on Sinop, Kastamonu, Ladik and Amasya region. A portion of them were published; but there are also some reports are not reached until now. It is the Fourcade's archaeological activities that make the Sinop consulate worthwhile in the world of science. But beyond this, archival sources on Fourcade's six-year consulate, gives us valuable information about on the situation of Anatolia in Age of Ayans at the beginning of the 19th century, Russian impact on the Black Sea and history of Ottoman-French relations in the Black sea. This study aims to make a review on Fourcade's Sinop consulate by using resources of the French archives.

Background - Mean platelet volume (MPV) is an indicator of platelet activation. The pathophysiology of the primary and secondary Raynaud's Phenomenon (RP) have not been completely established. The aim of this study was to investigate the relationship between MPV and RP. Materials and Methods - Our study was a prospective randomized study carried out from January 2011 to March 2012. The study group consisted of 39 patients: 27 (70%) patients having primary, 12 (30%) patients having secondary RP. An age-, gender-, and body mass index-matched control group consisted of 40 healthy participants. We compared the MPV in patients with RP and control participants statistically. Results - MPV of RP group was 8.79 +/- 1.37 femtoliter (fL) while MPV of control group was 8.39 +/- 1.36 fL. Comparison of MPV of RP group and control group showed no difference (p = 0.274). The mean of MPV was significantly higher among patients with secondary RP (9.76 +/- 1.68 fl) when compared with patients with primary RP (8.37 +/- 0.96 fl) (p = 0.018). Conclusion - The results of our study suggest that MPV may be used as a marker in secondary RP.

Atrial fibrillation (AF) is the most common sustained arrhythmia and associated with adverse outcomes and increased risk for thromboembolic events. Warfarin is still the most extensively prescribed oral anticoagulant in AF to prevent ischemic complications. We aimed to determine the differences at platelet indices with warfarin usage layered by International Normalized Ratio (INR). A total of 250 patients with permanent non-valvular AF (mean age 70.2 +/- 9.1; 153 female) were divided into two groups. Group 1 included 125 patients whose INR is between 2.0 and 3.0 (called as effective'') and Group 2 included 125 patients whose INR is <2.0 (called as ineffective''). Also 123 age- and sex-matched individuals in sinus rhythm enrolled as control group (Group 3). After physical and echocardiographic examination, complete blood counts and INR were studied. There was no statistically significant difference in age, sex, co-morbidities and medications, also hemoglobin, white blood cell and platelet counts among the groups. The CHA(2)DS(2)-VASc scores were similar between Groups 1 and 2. The mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) were significantly higher in Group 2 than Groups 1 and 3 and similar between Groups 1 and 3. MPV was positively correlated with PDW and PCT and also inversely correlated with INR value and platelet count. On multivariate logistic regression analysis, MPV, PDW and PCT were independent predictors of ineffectiveness of INR. The results of this study showed that MPV, PDW and PCT are increased in patients with non-valvular AF without effective warfarin treatment. Warfarin usage adjusted by INR is associated with lower values of these platelet indices, even lower as the values of subjects in sinus rhythm. MPV, PDW and PCT are independent predictors of INR ineffectiveness and seem to be useful parameters for monitoring the effectiveness of warfarin treatment.

Local scouring at piers of river bridges affects the bridge safety adversely. Proper design and implementation of scour countermeasures can limit potential bridge failures. This study deals with the description of a computer program developed in VB.Net language to design armoring type bridge scour countermeasures. This program is applied to a bridge located in Rize, Turkey. To this end, flow, bed material, and bridge structural characteristics are defined to determine the maximum depths of scour at bridge elements. Using this information, various alternatives are tested from constructional, geotechnical, hydraulics, and economic feasibility viewpoints. Based on a selection index, partially grouted riprap is found to be a suitable countermeasure for the cited project.

Gücer, Mehmet Ali; Aslan, Zafer
The Yoncayolu Metamorphic Rocks (YMR), exposed in the Sakarya zone (Erzincan, NE Turkey), consists mainly of greenschist rocks which are chlorite schists, muscovite-chlorite schists, metabasic rocks and lesser extent of pyhllites and calc-schists. All YMR are fine-grained, weakly foliated and often cut by quartz veins. The common mineral assemblage is chlorite+albite+epidote+quartz+/-clinozoisite+/-actinolite+/-opaques. Geochemically, protoliths of the YMR resemble calc-alkaline volcanic arc rocks. The YMR have high contents of large ion lithophile elements (LILEs) and low contents of high field strength elements (HFSEs) similar to mid-ocean ridge basalt (MORB). (La/Lu)(CN) values are between 0.26 and 6.16. The REE patterns show slight or no Eu anomalies (Eu-CN/Eu* of 0.48 to 1.13), suggesting minor plagioglase fractionation. 40Ar-39Ar dating on plagioclases from the metabasic samples of the YMR gave ages of 100.8+/-3.4 Ma (Albian) and 94.1+/-3.3 Ma (Cenomanian), suggesting that metamorphism was related to the closure of the Neo-Tethyan Ocean. Metamorphism took place during subduction of the Neo-Tethyan Ocean between similar to 90-70 Ma. Chlorite geothermometry yielded a temperature of 320-350 degrees C and a pressure around 4 kbar. All these findings lend support for greenschist facies metamorphic conditions during the formation of the YMR.

Nas, Salim Serkan; Nas, Evin
Leachate quality varies depending on many factors such as the depth and the content of solid waste, seasonal variations in solid waste, and the duration of storage of solid waste; design and operation of storage space; geological and hydrogeological characteristics of storage area; and environmental interaction of leachate, which affect each other. One of the two major sources of leachate is the moisture content of the waste stored and the other is the mass of water entering the storage area from outside. A major part of the mass of water entering the storage area from outside is the infiltration of rain water through the storage area. The purpose of this study is to assess the seasonal variation in leachate of Gumushane (Central) open dump area using the 'water balance method' for the determination of the factors affecting the seasonal variation in leachate of landfill, which particularly holds a higher risk of contaminating the environment. In addition, some of the measures to be taken in solid waste storage areas in order to minimize the mass of leachate are presented.

Patient: Female, 14 Final Diagnosis: Ovarian mucinous cystadenoma Symptoms: Abdominal enlargement center dot abdominal pain center dot constipation Medication: - Clinical Procedure: Specialty: Obstetrics and Gynecology Objective: Rare disease Background: Although ovarian tumors are most commonly observed in adults, they relatively rarely occur in children. The majority of ovarian masses encountered in the premenarchal or childhood stages are non-neoplastic lesions such as benign functional cysts. Epithelial tumors account for 8-10% of all ovarian tumors and are histologically classified as mucinous or serous. The most common benign epithelial ovarian tumor is cystadenoma. Case Report: We report the case of a 14-year-old premenarchal girl with chronic abdominal pain, constipation, and abdominal enlargement. A computed tomography detected a huge left ovarian cystic tumor. A 9-kg ovarian tumor was removed surgically. Pathology showed a benign mucinous cystadenoma (MCA). Conclusions: Ovarian neoplasms in children present a diagnostic quandary, and very often the diagnoses are missed or delayed. When the diagnosis is made, a prompt and fertility- preserving surgical treatment must be performed and followed to prevent recurrence.

Objective: To provide guidance in the selection of the appropriate patient for arthroscopic debridement. Materials and Methods: Ninety patients who were diagnosed with gonarthrosis according to modified American College of Rheumatology (ACR) criteria and who underwent arthroscopic debridement and meniscectomy were evaluated. Functional assessment of patients was made based on preoperative as well as 1 month and 1 year postoperative results of the Lysholm Knee Score and the Visual Analog Scale (VAS). One year postoperatively, the Tapper-Hoover Scoring System was used to calculate long-term results. Analyses were conducted using SPSS 18 software. For this study ethics committee approval was received from the ethics committee of Ataturk University Medical Studies Department Head on 08.10.2010 at the 6th meeting with regards to the document written on 16.06.2010 with number 998. Results: Differences between preoperative and 1-month and 1-year postoperative values in the Western Otorino and McMaster Universities Osteoarthrosis (WOMAC) Index, Lysholm and VAS were found to be statistically significant (p<0.001) (Table 1). According to TapperHoover results, 82.8% of patients benefited from arthroscopic debridement in the long term (Table 2). Among body mass index (BMI) groups, the WOMAC, Lysholm and VAS values of obese patients were worse than those of normal weight and underweight patients, and the difference was statistically significant (p<0.005). Late-term results of patients younger than 55 were superior to those over 55. Conclusion: In the treatment of patients with gonarthrosis, arthroscopic debridement is a good option. Patients who have a low BMI and are younger than 55 years old experience more benefit from arthroscopic debridement.

Durmaz, Mustafa; Daloglu, Ayse
In Turkey many roofs exposed to snow loads exceeding the design snow loads are damaged or collapsed. Roof snow load specified for structural design in Turkish codes is calculated as the product of a ground snow load multiplied by the conversion factors that depend on the roof properties. In this study, the ground snow loads in Turkish codes are evaluated via statistical analysis of Turkey snow data obtained from 92 Turkish State Meteorological Service stations. The probability plot correlation coefficient test for Gumbel, lognormal and Weibull distributions are used to determine the best fit of the probability distribution considering the snow data. 50-year design ground snow loads and snow depths of the stations determined by using the selected distributions are compared to those proposed in Turkish codes. It is concluded that TS 498 is unsafe for Eastern Black Sea and Eastern Anatolia regions and Gumbel distribution used in TS 7046 does not represent half of the snow data.
