Komut, Osman
One of the most important stakeholders in the sustainable management of non-wood forest products (NVVFP) is the forestry organization employees. In this study, the analysis of the perception, awareness and opinions of the forestry organization employees concerning the sustainable management of NWFPs was determined as the main aim. The study was conducted with a research pattern consisting of a questionnaire and semi-structured questions for employees at the level of employees, forest guards, office clerks and engineers within two different Regional Directorates of Forestry in Turkey. Mann Whitney U and Kruskal Wallis H statistical analysis tests were utilized for determination of the differences of opinions based on the variables. In the research, statistically significant (p<0.05) differences of opinion were determined based on the sub-groups of variables of the regional directorate, activity, receiving training, occupation, educational background, and gender. Research results have proved that the number of NWFPs which are evaluated economically and are harvested in a controlled manner is very low. It has been determined that the forestry organization employees don't find the work on NWFP adequate and they are concerned about the sustainable management of NWFPs.

Komut, Osman
Forest industry enterprises that process round industrial wood are the biggest consumers of the forestry sector. In this study, micro-scale forest industry enterprises that process round industrial wood are investigated. Questionnaires based on face-to-face interviews were utilized as a data collection tool. The raw material storage areas of 48 enterprises, visited during the study, were subjected to direct observation and examination in terms of storage methods, conditions and damages in logs. The ratio of the enterprises participating in the total number of enterprises in the study area occurred as 64%. The relationships between the defined variables were analyzed with the Chi-square independence test. The analysis of variance was used to determine the relationship between independent variables. The results showed that raw material supply methods of enterprises differ, and they vary as the enterprise size grows. The annual average revenue was a variable that caused statically significant differentiation (p<0.05) in the raw material supply methods between enterprises. The results proved that the supply of raw materials with the stumpage sale method increased the risk of bark beetle damage in logs. Improper storage methods and conditions were identified as causes of significant blue discoloration damage in coniferous tree logs.

Canbolat, Deniz; Turan, Ibrahim; Küpeli, Yunus Emre; Kilinç, Sedanur; Piliç, Sevim
Propolis, which has been used in traditional medicine for hundreds of years all over the world, is a resinous natural product with a complex content obtained by honey bees by mixing the buds of plants and pollen grains with enzymes they secrete. Propolis may have different contents due to the gathering region, plant source, bee variety and climate of the place where it is collected. Although there are many studies related to different regions, so far the propolis of the Savsat region in Artvin have not been studied yet. The aim of this study is to determine the antioxidant properties (determination of iron reducing power, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total phenolic and total flavonoid content) of propolis extracts of Artvin Savsat region prepared with phosphate buffer salt solution (PBS) prepared at different temperatures (45 and 60 degrees C) and to determine the erythrocyte hemolysis inhibition properties of the extracts. Total phenolic (11.91 +/- 0.5-24.14 +/- 1.38 mg gallic acid equivalent to g propolis) and total flavonoid (1.79 +/- 0.03-2.13 +/- 0.07 mg quercetin equivalent to g propolis) content of PBS extracts, iron power determination (12.80 +/- 0.36-27.15 +/- 0.12 mg ascorbic acid equivalent to g propolis), 2,2-diphenyl-1-picrilhydrazyl (DPPH) radical scavenging activity (%22.86 +/- 0.5-31.24 +/- 1.33) and erythrocyte hemolysis inhibition (%55.58 +/- 0.57-96.37 +/- 0.02) were determined using spectrophotometric methods. As a result of the experiments, it was determined that the extract with PBS obtained at a temperature of 60 degrees C was higher than the extract obtained at 45 degrees C, in terms of antioxidant properties and erythrocyte hemolysis inhibition ratio. Further studies are required to identify molecules that inhibit erythrocyte hemolysis in extracts and have antioxidant properties.

Hacikelesoglu, Hizir
Moral disengagement is a phenomenon that is at the centre of life in terms of being frequently referred to in social life. The fact that young people (as moral agents) are at the centre of criticism on moral issues makes it necessary to examine the areas in which young people are engaged and affected during this period. In this context, the present study aims to examine the relationship between social media addiction, religiosity and moral disengagement on a sample group of individuals aged 13-18. For this purpose, the research was designed according to the relational screening model, one of the quantitative research methods. The research data were collected through a sample group consisting of 415 people selected by the convenience sampling method. In the analysis of the obtained data, correlation and regression analyzes were performed by using SPSS 21. As a result of the research, there is a positive relationship between social media addiction and moral disengagement. On the other hand, a negative relationship was found between religiousness and moral disengagement. It has been determined that social media addiction and religiousness predict moral disengagement in opposite directions. In addition, it has been observed that religiosity is not a determining factor on social media addiction.

Çelik, Orkun; Erer, Elif
We aim to explore the role of gender in the government expenditure and unemployment nexus at regional level for Turkey. For this aim, we use the dataset covering the period 2004-2019 for 26 NUTS-2 regions in Turkey and employ a panel ARDL approach. The obtained empirical findings show that government expenditure and gross domestic product per capita provide overall, female, and male unemployment rates to diminish in the long term, which means the Keynesian approach is valid on the long term. Nevertheless, on the short term, government expenditure induces rises in the male and female unemployment rates. This result indicates the validation of the Abrams Curve Hypotesis in male and female unemployment rates on the short term. Also, inflation rate increases overall and male unemployment rate on the long term, but having significant and positive impact on only female unemployment rate on the short term. All these findings show that gender has a significant role in this nexus. The expected contribution of this study to literature is to investigate the impact of government expenditure on unemployment by gender at regional level for Turkey. We are of opinion that our empirical findings can guide policy makers in active plans fighting unemployment.

Karademir, Aysenur; Unver, M; Tanriverdi, M
This study aims to discover the history of Akbaba village, which is located in the Beykoz district of Istanbul. It was named after Mehmed Efendi, who was a dervish ghazi from Mehmed the Conqueror's anny. He built a dervish lodge, tekke, worshipped there until the rest of his life, and was then buried near it. Mehmed Efendi was known as Akbaba Sultan among the public, and his tomb has been a sacred place visited by Muslims since then. Canfeda Khatun, a ketkhuda wormy: of Sultan Murad M.'s harem, established a mosque and other main buildings there as part of her pious foundation, waif, and a village arose around them at the end of the sixteenth century. That was the way the land became a residential area during the Ottoman period. However, the waqf accounting registers reveal that there was more on Canted& Khatun's mind as the tekke's followers were janissaries in Akbaba. The village stayed as the way it was until 1826 when Sultan Mahmud II abolished the ocak of Janissaries, ending all their tekkes, including the one in Akbaba. As its followers were exiled, Canfeda's waqf lost its importance in the village. It seems that nobody remembers the significance of her waqf at Akbaba today besides the name of Canted& Khatun. This work explores the roots of the village through the help of archival documents, especially from the waqf accounting registers.

Demir, Sertac Timur
This article argues that a clear correlation exists between disease and the prevailing social functioning. In this respect, every disease can be seen as a metaphor for the age and society in which it emerges. In other words, every period carries a form of disease that bears traces of the dominant lifestyle. This study approaches the epidemic as a kind of sociological projection in the context of studying modern culture and continues the discussion along the lines critically opened by Susan Sontag (2005). lust as Sontag examined disease as a metaphor, this article debates the discourses on masks, social distancing, and hygiene within the scope of COVID-19 along a specific sociological axis around the concepts of speed, control, information, hyper-medicalization, and death as the dominant indicators of contemporary culture. For this purpose, the study seeks answers to the following questions through the leading social theorists of the field such as Bauman, Baudrillard, Turner, Furedi and Chul-Han: How does the global epidemic and the current health discourse embodied in it appear within the sociological context? What thoughts and tendencies emerge when examining the pandemic portrait as a social metaphor? For example, what kind of relationship exists between hygiene and cultural fears; among distance, social isolation, and avoidance; and between masks and the superficial idea of death concealed behind quantification? Undoubtedly, the pandemic is a critical breaking point in the history of modern medicine and has forced not only global health practices but also many value judgments to both paradoxically be accepted and questioned.

Electroencephalography (EEG) signals recorded during sleep are divided into 30-second segments and analyzed by experts and classified into sleep stages, and in this way, diagnosis and treatment of diseases are made. Computer-assisted sleep scoring systems can effectively reduce the burden of experts by classifying sleep stages. In this study, after preprocessing of the EEG signals, four features were obtained for each EEG band (20 features in total) with the autoregressive model and then classified with three different classifiers common in machine learning. The proposed method was tested on the data set called ISRUC sleep (Subgroup 3, ISRUC3) and the results were compared with the results of other studies. The results show that the proposed method is more successful than other existing methods, despite the use of fewer features.

Purpose Acute pulmonary embolism is a life-threatening cardiothoracic emergency leading to right ventricle systolic and diastolic dysfunction. In the present study, we investigated the right ventricle diastolic function and its predictive value in patients with acute pulmonary embolism. Material and methods Were prospectively recruited in this study 621 patients diagnosed with acute pulmonary embolism between December 2015 and June 2019. Among them, 173 were excluded, leaving 448 patients for follow-up. Transthoracic echocardiography was performed for the evaluation of the right ventricle systolic and diastolic indices. At 30-day follow-up, the patients were allocated either into the benign or in the complicated clinical course group. Results The group with complicated clinical course had higher value of pulmonary artery systolic pressure (PASP), right/left ventricle diameter ratio, E-wave velocity, E/A ratio, A ' wave velocity, E/E ' ratio, and time interval between E and E ' waves (P < .05), but lower values of tricuspid annular plane systolic excursion, A-wave velocity, isovolumetric relaxation time, deceleration time, E ', and E '/A ' (P < .05). Complicated clinical course was associated with shorter isovolumetric relaxation time (r = .564, P < .001), E/E ' (r = .495, P < .001), and TE-E ' (r = .596, P < .001). Receiver operator characteristic curve analysis showed that TE-E ' had the largest area under curve (TE-E ' 0.82, IVRT 0.77, E/E ' 0.72). A cut-off value of TE-E ' = 70 milliseconds had an 81.1% sensitivity and 71.4% specificity for the prediction of the complicated clinical course. Conclusion The assessment of the right ventricle diastolic function could predict the complicated clinical course in patients with acute pulmonary embolism.

Idil, Eral; Aydin, Ali Ekrem; Bulut, Esra Ates; Isik, Ahmet Turan
Aims: Older adults are at risk for polypharmacy, which has multidimensional safety, clinical and economic implications. Therefore, the optimization of drug therapy is one of the critical components of geriatrics clinical practice. This study is aimed to investigate the effect of drug rationalization on comprehensive geriatric assessment(CGA) parameters. Materials and Methods: The study was a retrospective and longitudinal study examining the effect of change in drug number on functionality and physical performance. A total of 515 patients were included in the study. Detailed medication history, laboratory findings, CGA parameters were recorded in the first admission. Polypharmacy was accepted as concurrent usage of five or more drugs. Medications of each patient were reviewed with the guidance of CGA and Beers Criteria. Results: The mean age of patients was 74.13 +/- 7.29 years, and 68.7% were female. The baseline mean number of drugs was 5.11 +/- 3.34. The polypharmacy group(269 patients) had a higher rate of geriatric syndromes and lower CGA scores in the first admission. After optimization of medications, the mean drug number decreased to 4.76 +/- 2.72. Depression, mobility and nutritional scores improved at the end of six months in the patients whose total number of drugs decreased, while global cognition, activities of daily living scores, and gait speed were preserved. Increasing the number of drugs was associated with lower mobility and functionality. Conclusion: Drug rationalization guided with CGA improves the nutritional, physical, and psychosocial status of geriatric patients. Thus, medication reviews have key importance in the management of older patients.

Background Cholesteatoma-related bone destruction is the cause of many complications due to chronic otitis media. This study aimed to evaluate osteoclastic activity in cholesteatoma-related bone destruction using tartrate-resistant acid phosphatase 5b, an enzyme specific to osteoclastic activity. Method Seventy-two patients diagnosed with chronic otitis media were included in this study and were divided into two groups: with and without bone destruction. The blood serum and tissue tartrate-resistant acid phosphatase 5b levels from both groups were compared. Results There were no significant differences in the level of serum enzymes between both groups. However, in tissue samples, tartrate-resistant acid phosphatase 5b levels were significantly lower in the bone destruction group than the group without bone destruction. Conclusion This study determined that the level of tartrate-resistant acid phosphatase 5b, a specific enzyme for osteoclastic activity in cholesteatoma-related bone destruction, is locally decreased. This data suggests that osteoclastic activity may decrease in cholesteatoma-related bone destruction. However, further experimental and clinical studies are required to clarify this highly complex mechanism.
