Göktas, Ozlem; Gidik, Betul
The importance of medicinal and aromatic plants in people's lives is growing due to their various uses and diverse cultivation conditions. This study aimed to determine the yield and yield components and quality features (oil ratio and fatty acid composition according to GC-MS) of six different tarragon (Artemisia dracunculus L.) local breeds grown organically in Bayburt province, Turkey. For this purpose, the data obtained by growing the plants in the experimental area during the two crop years, 2018 and 2019, were evaluated. As for the yield values, the highest values for green herb yield (275.41 kg ha-1), drug herb yield (99.89 kg ha-1), drug-herb percentage (44.00%), green leaf yield (208.97 kg ha-1), green leaf percentage (75.09%) and drog leaf yield (72.48 kg ha-1) were found in the local breed from Bayburt Central location. It was found that the oil percentages, evaluated to determine the quality traits, ranged from 5.39% to 7.02%. The most important fatty acid was alpha-linolenic acid (9.49%-23.1%), followed by linoleic acid (4.18%-13.89%) and palmitic acid (4.05-13.89%). As far as we know, this is the first study investigating tarragon's total oil content and fatty acid composition. The results show that the total oil content of this plant, which has remarkable pharmacological effects, is present in useful quantities compared to the leafy green and does not contain fatty acids that prevent its consumption as food. Therefore, this plant is expected to be used directly in various food products.

- MakaleAçık Erişim2021Estimation of shear strength parameters of a high plasticity clayey soil stabilized with lime at different curing temperatures using Response Surface Methodology (RSM)
Kamiloglu, Hakan Alper; Turan, Huseyin
Response Surface Methodology (RSM) is useful to find the optimum value of the response, to examine the relationship between independent variables and responses, or to shorten very complicated and timeconsuming numerical analyses. Although the RSM is a commonly used method in many branches of engineering, the use of this method is limited in geotechnical studies. In this study, the effect of curing temperature on shear strength and unconfined compressive strength parameters of lime stabilized clayey soil was examined. Within the scope of the study, it was aimed to evaluate the Response Surface Method to estimate these parameters with less experimental effort. In the study effect of the temperature was controlled with five different curing temperature level (3 degrees C, 13 degrees C, 23 degrees C, 33 degrees C, 43 degrees C). Three axial (UU) and unconfined compression tests were performed on 40 pieces of stabilized soil samples cured along 28 days at various temperatures. The experimental design was performed with Response Surface Methodology to reduce the test number. Within this scope, an equation was derived statistically to estimate the deviator strength of the samples. Statistical analyses were performed considering deviator strengths of the 18 pieces of samples. As a result of the study, it was seen that it is possible to estimate shear strength and unconfined compression strengths of the samples accurately by using fewer test numbers with Response Surface Methodology.

Gültekin, Omer Faruk
One of the important results of economic development is the development of trade and the increase in welfare. A reflection of the increase in welfare is the prolongation of human life and the increase in urbanization. Through these indicators, societies are expected to develop economically and socially. In this study, as a reflection of welfare, the effect of commercialization, average life expectancy and urbanization on income inequality in the Commonwealth of Independent States countries and some Baltic countries that gained independence after the dissolution of the Soviet Union after 1991 were investigated. In the study, trade openness and the share of countries in world trade representing commercialization, urbanization representing the increase in welfare, and disposable Gini coefficient and market Gini coefficient representing income inequality examined. For the estimations, four models were created and different results were obtained for each model. In the analysis process, descriptive statistics, correlation matrix, multicollinearity, cross-section dependence, heteroscadasticity, autocorrelation tests were applied. Depending on the test results, the Driscoll-Kraay test was applied and the results were estimated. According to the results, it can be said that while commercialization has a positive effect on income inequality, urbanization has a negative effect on income inequality.

Dayi, Ozkan
Throughout history, one of the most critical indicators of city life has been the organization of tradesmen. We observe that the merchants' structure evolved in response to the commercial, agricultural, and economic activities of people residing in the city center and its surrounding areas. We know that merchants, especially in the Iranian geography, were significantly affected by political and military activities and were shaped in a way that was dependent on political institutions throughout the Middle Ages. Tradesmen, who held a vital place in the city's structure and life within the Turkish-Islamic civilization, were significantly impacted by the Mongol invasion. We know that the merchant organization regained its essential place in city life during the Ilkhanate period, which re-established political unity in Iran and Western Asia after the Mongol invasion. During the Ilkhanate period, officials from the tradesman organization who supervised and chaired the organization were appointed by state administrators. Moreover, this structure supported the local administrators - usually bearing the title h & amacr;kim - who were appointed by the central authority to ensure the easier governance of cities. In the Ilkhanate state, members of the market and merchants' organizations regularly expanded their areas of activity. In this context, the article will discuss the organization of merchants within the city structure of the Ilkhanate state, providing details.

Kilinç, Mehmet
This study aims to reveal the mediating role of Machiavellianism in the effect of abusive supervision on knowledge-hiding behavior and the moderating role of moral identity in the relationship between Machiavellianism and knowledge-hiding behavior. The study adopts the Conservation of Resources (COR) Theory as its theoretical framework. Quantitative data were obtained from 408 healthcare professionals using the survey method. The analyses conducted via SPSS, AMOS, and Process Macro revealed that abusive supervision significantly increases knowledge-hiding behavior (beta = .855) and Machiavellianism (beta = .820). Furthermore, Machiavellianism acts as a mediator in the relationship between abusive supervision and knowledge-hiding. A notable finding is that moral identity acts as a moderator (beta = .134), strengthening the positive effect of Machiavellianism on knowledge-hiding behavior. Considering the analysis results, some suggestions specific to healthcare institutions, healthcare workers, and future studies were presented. Theoretically, this study contributes to the Dark Triad literature by demonstrating how abusive environments trigger resource conservation through knowledge-hiding. Practically, suggestions for preventing toxic leadership and improving ethical climates in healthcare institutions are presented. Health institutions should implement a reward system for employees who demonstrate helpfulness and teamwork to decrease Machiavellian behaviors.

Aktas, Yasemin
Marriage, which is the smallest structural unit of the society and where the foundation of the family was laid, was made a part of politics by the states and implemented. There are many reasons for attempting marriage between states, and many factors can be listed, such as ending wars, the continuation of peace, acquiring allies, and being able to leave an heir. Starting from the 11th century, in the Rupen dynasty that emerged in cukurava, political marriages were made in order to gain strong allies and dominate the region starting from the baron Constantine. Relationships were established with the Latin kingdoms, the Byzantine state of Nicaea, and the Crusader counties by exchanging daughters. In addition to political and military reasons, the desire of the Crusader counts to obtain financial benefits through dowry was also effective in the marriages, most of which were with the Crusader counts and Latin kings. Marriages, where arbitrariness was not in question, could start and end under certain conditions under the control of the church. In this study, the purposes, processes and termination of marriages performed by the Rupen dynasty that emerged in cukurova were discussed.
