Çomaklı, Şafak Ertan; Merddan, Kurtuluş
Türkiye’de Cumhuriyet’in kuruluşundan 1980 yılına kadar olan dönem boyunca tarıma dayalı bir ekonomi benimsenmiş, nüfusun çoğunluğu tarım sektöründe istihdam edilmiş ve tarım korumacı politikalarla desteklenmiştir. 1980 sonrası alınan kararlarla birlikte serbest piyasa ekonomisine geçiş süreci başlamış ve tarımı desteklemeye yönelik politikalar da azaltılmıştır. 1980 sonrası uygulanan iktisat politikaları; üretimin, işgücünün, sermayenin ve sosyal politikaların yeniden yapılanmasını, dış ticaret ve mâli piyasaların ulusal ve uluslararası akımlarda serbestleştirilmesini hedeflemiştir. Ortaya konulan bu politikaların sektörel bazda farklı yansımaları olmuştur. Bu çalışmada; 1980 sonrası Türk tarımın sektörel yapısı, Türkiye ekonomisindeki yeri ve 1980 sonrası yabancı sermayenin sektörel dağılımı ele alınmıştır. Bu kapsamda geçmişte uygulanan tarım politikaları kısaca ele alınıp, 2000 sonrası yapısal düzenlemeler, yabancı sermaye hareketlerinin dönüşüm süreci ve yabancı sermayenin gelecek eğilimleri değerlendirilmeye çalışılmıştır. Çalışma, yerli ve yabancı alan yazınından ve çeşitli kurumlardan elde edilen verilerden faydalanılarak hazırlanmıştır. Bu çalışma ile, bu alanda yapılanları bir araya getirerek mevcut eksiklikleri dile getirmek hem de gelecekte benzer konularda çalışma yapmayı düşünenlere yol gösterici olmak hedeflenmektedir.

Ceylan, Hüseyin; Kaplan, Ahmet; Bekar, Murat
Work accidents are serious issues that disrupt harmonious environment in workplace. They cause not only death, injury or disability of employees, but also serious financial loss for businesses and countries. Work accidents are highly preventable incidents, when necessary, precautions are taken. Like the whole world, in Turkey also there are risky sectors where work accidents are intensified. The identification of risky sectors in Turkey, is the first step of being able to fight against work accidents in this sector. Therefore, in this study the riskiest sectors in Turkey were investigated basing on the official accident data from the last ten years. Thus, first of all, the sectoral distribution of work accidents, death and permanent incapacity cases that occurred in Turkey in 2010-2019 was examined. Sectors were evaluated in terms of six different parameters: the number of work accidents, the number of deaths because of work accidents, the number of permanent incapacities because of work accidents, general accident incidence rate, fatal accident incidence rate, and permanent incapacity accident incidence rate. The top ten sectors with intensity have been determined for each parameter. Then, all these data were combined and the ten most risky sectors in Turkey in terms of work accidents were defined. In the last 10 years, the sector of "41-Building Construction" has been found to be the riskiest sector in Turkey, where the most work accidents have occurred, the most employees die and the most employees are permanently disabled. On the other hand, the "05- Mining of Coal and Lignite" sector, in which the general accident incidence rate, fatal accident incidence rate, and permanent incapacity accident incidence rate values are the highest, was the second most risky sector.

Introduction: Patients do not feel competent in managing their post-heart surgery processes. They need access to the right information to manage their symptoms. A mobile app is the right tool for this process, with its accessibility and reminder features at any time. We investigated the effects of 4-week mobile app training on respiratory functions and maintenance of drug compliance in patients after heart surgery. Material and methods: This paper reported the findings of an experimental study, which recruited a total of 120 participants of whom all underwent heart surgery. The following outcomes were measured: TriFlo results, the Morisky Questionnaire - self-reported measure of adherence, and results of the Symptom Interpretation Questionnaire. Results: All groups showed a significant difference in Symptom Interpretation Scale subscales after using the mobile app. When the results of the research are evaluated, it can be said that there is a need for nurses to produce new-generation technological equipment to meet the needs of new products to be used in the field of health. Conclusions: Individuals can solve their post-operative symptom management problems with a mobile app. The use of a mobile app positively contributes to the management of the 2 most common symptoms after heart surgery. Mobile apps are used in many disease processes in the world. The results of these studies contribute to the limited information presenting results regarding drug compliance and lung capacity in patients with a bypass between mobile apps.

Ozyurt, E.
This study numerically investigated the elevated temperature resistance of earthquake-damaged square hollow section (SHS) T-joints subjected to brace axial compressive load. The residual stresses and deformations due to the earthquake were obtained from a pushover analysis. The extensive numerical simulations were analyzed using nonlinear finite-element software to examine the effects of the beta ratio, gamma ratio, damage level ((D) over cap), and initial applied load (n(f)) on the fire resistance of SHS T-joints after verification of the numerical simulations based on the available test results in the literature. The results indicated that the fire resistance of SHS T-joints with axial compressive load in the brace member decreased significantly due to the residual stresses and deformations from the earthquake. This situation worsened in all numerical models as the damage level increased. The reduction rate of the critical temperature at various damage rates was independent of the initially applied load ratio, but the loading rate directly affected the fire resistance of the joint regardless of the earthquake. As the beta ratio decreased, the yielded area at the brace-to-chord intersection region increased. Thus, the critical temperature of the joints at a constant damage level was inversely proportional to the beta ratio. Joints with a large gamma ratio had larger residual stresses and deformations than those of corresponding joints with a small. ratio. Therefore, the fire resistance of the joints after the earthquake decreased as the chord-wall thickness decreased. The critical temperature of the joints with either a large beta or gamma ratio was limited by the deformation limit at high damage levels. The fire resistance of the SHS T-joints after the earthquake decreased due to residual stresses and deformations. That effect increased even more in joints with high beta and. ratios.

Recepoglu, Mursit
This study has examined the causality relationship between public expenditures, economic growth and income inequality for transition economies called the Commonwealth of Independent States (CIS). In the study, in which the 1998-2019 period was analyzed, the effects of public expenditures on economic growth and income inequality were determined with the bootstrap panel causality test. Bootstrap panel causality test results show that there is a one-way causality relationship from public expenditures to economic growth for Armenia, Belarus, and Kazakhstan. On the other hand, a one-way causality relationship has been determined from public expenditures to income inequality in Belarus and Kazakhstan, and from income inequality to public expenditures in Kyrgyzstan. In Moldova and Russia, however, no causal relationship could be obtained between the variables. The overall evaluation of the findings obtained from the panel causality tests concluded that public expenditures in CIS member countries are closely related to both economic growth and income inequality. CIS member countries need state interventions in order for the market system to fully settle in transition period. However, implementing policies that do not exclude private investments and do not harm the functioning of the market economy should be elaborated during practicing public expenditure policies in these countries in transition.

Sever, Mehmet Onur; Zambak, Omer
In this study, the effect of 12-week basic swimming training of sports science students on some respiratory parameters was determined. In the 2nd, 3rd and 4th grades of Gumushane University School of Physical Education and Sports, 64 (111) male students who did not take swimming lessons and 47 who took swimming lessons participated voluntarily. The experimental group was given breath work for 12 weeks during the course content and for 10 minutes at the end. Measurements were taken from the students twice before and after the 12-week education. SPSS 25.0 program was used in the analysis of the data collected within the scope of the research. Independent comparison of age, height and body weight measurements of the athletes in the experimental and control groups. Samples T Test was used. In the comparison of time, group, group x time changes of FVC, MVV, VC and FEV1 measurements, Repeated Measures ANOVA analysis was used. Statistical significance level was taken as (p<0.05). As a result of the research, a significant result could not be reached in FVC and FEV1 values between Tests, Groups and Group x time intervals, whereas VC was only between tests. However, statistically significant differences were found between MVV and VC Tests, Groups and Group x Time values. In short, it has been shown that students who take swimming lessons have statistically higher lung volumes than students who do not take the lesson. However, swimming activity can be recommended to increase respiratory efficiency of university students.

Demir, Sertac Timur
In this article, everyday technology, which tends to expand without limits, is discussed in the context of contemporary practices that start from antenatal to death and that correspond to the desire for immortality of modern man. For this purpose, it is examined how technology intervenes in life and death through the episodes of Arkangel, Right Be Back, and San Junipero in Black Mirror, the popular science fiction series. In this study, the current social and human dilemmas that appear in the narratives are discussed, without ignoring the technical analysis of the series. In this respect, gene based medical studies that reformat the body, smart and synthetic technologies that add a new dimension to digital control and surveillance, contemporary medical and technoscientific assumptions about death and immortality are debated. The theoretical framework of this article consists of theoreticians such as Jean Baudrillard, David Le Breton and Byung Chul Han who consider that the change in social structure and relations is mainly driven by technology and critically approach this unavoidable trend. According to the main argument and inference of this research, technologies that can descend to every part of the body are no longer just the comfort and convenience extensions of daily lite, and they affect almost all ontological processes between existence and extinction by being articulated with human destiny. However, this global trend is also the loss of the natural and the real for the modern characters who are deprived of the human conditions such as pain and death that make life precious.

Kaya, Asli Uner
Some philosophers of mind claim that non-reductionist physicalist theories of the mind cannot explain the causal interaction between consciousness and the physical world. The problem is about explaining how consciousness, which cannot be reduced to physical processes, interacts with the physical world without violating the laws of physics. John Searle claims to have solved the problem of mental causation in his theory of mind, which he calls Biological Naturalism, exhibiting a non-reductionist attitude. In this study, I aim to evaluate Searle's solution to the problem of mental causation. For this purpose, I will first touch on mental causation and how it is understood. Then, I will outline the problem and address the specific criticisms against non-reductionist physicalists. Finally, considering these criticisms, I will show under what conditions Searle's solution to the problem of mental causation can be accepted as correct.

Çelik, Meryem; Ilyasoglu, Huri
The aim of this study was to investigate the effect of black lentil flour (BLF) on the quality of wheat bread. The control bread with wheat flour and BLF-supplemented breads (2, 6 and 10 %, respectively) were prepared and analyzed in terms of proximate composition, physicochemical and sensorial properties, total phenolic content (TPC), and antioxidant activity. The BLF-supplemented breads provided significantly higher protein compared to the control bread (p < 0.05). Moreover, it improved significantly TPC and antioxidant capacity (p < 0.05). However, the addition of BLF reduced significantly the specific volume of the bread, L* and b* values of both crumb and crust (p < 0.05). The BLF had no influence overall acceptability. Our findings revealed that the BLF may a have potential use to enhance the quality of wheat bread.

Abis, Selmani
The goal of the study is determining the relationship with football players' positive thinking skills and sportsmanship orientations. The study consisted of a total of 690 football players in 30 teams competing in the 1st, 2nd and 3rd groups of the 4th region of the regional amateur league organized by the Turkish Football Federation in 2021-2022, and the sample consisted of 149 athletes voluntarily participating in this universe. Personal information, positive thinking and sportsmanship orientation scales were used collecting data. Statistical analysis was performed on a computer environment. Pearson moment product correlation analysis (r) was applied. As a result, it was determined that the positive thinking skills and sportsmanship orientations of the regional amateur footballers were at a level that could be considered high. A positively moderate correlation was seen between positive thinking skills and sportsmanship orientations sub-dimensions and total scores. Athletes competing in this league, which is the last stage of the transition from amateur to professional, are considered to be semi-professional and it is thought that their ability to resist various pressures such as psychological and physiological in challenging competitions is due to their sportive experience and abilities.

Avci, Ibrahim
The concept of consumption, which has an important place in people's lives, is generally expressed as the use of produced goods and services in line with needs. Consumption now includes the psychological needs of people as well as their physical needs. Consumers can buy things they do not need by acting pleasure-orientedly, and they exhibit consumption behaviors to provide psychological satisfaction. One of the consumer-purchase patterns is found to demonstrate others in the social environment. Therefore, non-need consumption focused on pleasure and display causes excessive consumption; this situation can also cause wastefulness. Accordingly, in the present study, the aim was to examine the effect ofconspicuous consumption behavior on wasteful consumption behavior and the mediating role of hedonic consumption behavior in this effect. With the online survey form prepared, 519 participants were reached between the dates of 21.05.2020-06.07.2020. The data obtained were analyzed with the SPSS 21, AMOS 24, and PROCESS 3.5 programs. After the analysis, it was concluded that conspicuous consumption behavior has an effect on wasteful consumption behavior and that hedonic consumption behavior has a mediating effect.

Purpose The author investigates the effects of human capital on labor income share in the 15 sectors of the European Union (EU)-13 countries and the United Kingdom (UK) over the period 2008-2015. Design/methodology/approach The author employs pooled ordinary least squares (OLS) estimation with panel data, using the EU KLEMS database. Findings The results show that when education level increases, labor income share increases and gender-based labor income share differentials decrease. Return to education is higher in qualitative sectors in contrast with the other sectors. Moreover, there are gender-based labor income share differentials at the sectoral level. These differentials are higher in nonqualitative sectors, while they are relatively lower in qualitative sectors. Research limitations/implications The biggest limitation of the study is that the data range cannot be expanded because of the database. The author is of opinion that the empirical findings will guide to policy makers in terms of wage setting. Originality/value The expected contribution of this study to the literature is to investigate the effect of human capital on labor income share at the sectoral level for the EU-13 countries and the UK. As far as the author knows, there is no study which investigates this topic at the sectoral level such a comprehensive, in the literature.

Esmaeilzad, Nasim Seyedpour; Dino, Ipek Gursel; Güney, Dilara; Yildirim, Yusuf Ersoy; Turan, Rasit; Özden, Talat; Amaducci, S
Agrivoltaic systems combine soil-grown crops with photovoltaic (PV) panels erected several meters above the ground. Combining solar panels and food crops on the same land can maximize land utilization. Under the PV panels, however, microclimate factors like solar radiation, air temperature, humidity, and soil temperature change. An agrivoltaic system must optimize sunlight sharing between solar panels and crops to maximize food energy production. It has been challenging to improve and analyze the performance of agrivoltaic systems due to the lack of a defined crop-specific parameter. In this work, we present a practical option to partially replace bifacial modules with semi-transparent ones, providing comparable levels of crop protection and greater climate change resilience while generating green energy and increasing land-use efficiency. The agrivoltaic system must be tailored to satisfy the needs of crops. For this purpose, a simulation model was conducted, which examined the impact of module transparency and cell layout based on light availability.

Ulukavak, Mustafa; Yalçinkaya, Mualla; Kayikçi, Emine Tanir; Öztürk, Serkan; Kandemir, Raif; Karsli, Hakan
In this study, the relationships between possible ionospheric total electron content (TEC) anomalies and earthquake focal depths and fault types were investigated using 3,099 global earthquakes with Mw >= 6.0 between 2000 and 2020. The relationship between the ionospheric TEC changes and earthquakes has been previously discussed in the literature. However, very few studies have examined the relationship between the focal depths and the fault types of these earthquakes. In general, three indices, namely the disturbance storm-time index (Dst), the planetary geomagnetic activity index (Kp), and the solar flux (F10.7), are used to characterize the space weather conditions (SWC) that affect TEC anomalies and to identify the active/quiet days for future earthquakes. In this study, 13 different indices were used: indices that measured solar activity included proton flux (Pf) at six different energy levels, F10.7, and extreme ultraviolet (EUV0.1-50 nm and EUV26-34 nm). Meanwhile, geomagnetic storm indices included Dst, Kp, the z-component of the magnetic field index (Bz), and proton density (P-d). By using the ionospheric TEC values derived from global ionosphere maps (GIM-TEC), both negative and positive ionospheric TEC anomalies were observed for 15 days before and 4 days after the earthquakes using a statistical analysis technique that involved a 15-day moving median. The earthquakes were grouped according to their fault types (normal, thrust, and strike-slip) and focal depths (shallow, intermediate, and deep). Their relationships with the negative and positive TEC anomalies in the quiet days before the earthquake were examined. Negative and positive anomalies were observed approximately 3-12 days before earthquakes that occurred on normal faults, approximately 5-8 days before earthquakes that occurred on thrust faults, and approximately 1-12 days before earthquakes that occurred on strike-slip faults. The average TEC anomaly changes were calculated to be 43.4% total electron content unit (TECU) for normal faults, 44.8% TECU for thrust faults, and 41.3% TECU for strike-slip faults. Positive anomaly values were exhibited by larger earthquakes on normal and thrust faults, whereas negative anomaly values tended to occur on strike-slip faults. Negative and positive TEC anomalies were detected around 3-12 days before shallow earthquakes, around 1-13 days before intermediate-depth earthquakes, and around 1-12 days before deep earthquakes. The average TEC anomaly changes were calculated to be 44.4% TECU for shallow earthquakes, 43.3% TECU for intermediate-depth earthquakes, and 42.6% TECU for deep earthquakes. Positive anomaly values were also found to be higher than the negative anomaly values in each group. We propose that there is a relationship between the ionospheric TEC anomalies that occur before large earthquakes and their fault types and focal depths. (C) 2022 American Society of Civil Engineers.

Objective: Thyroid gland surgery and its surgical complications are situations that a surgeon frequently encounters in his daily practice. In our study, it was aimed to examine the effect of different treatment methods given to patients who underwent thyroidectomy on hypocalcemia. Material and Methods: Three hundred and seventy-one patients who underwent thyroidectomy at Ondokuz Mayis University Medical Faculty General Surgery clinic between December 2016 and January 2021 were retrospectively included in the study. Parameters such as surgery indications, fine needle aspiration biopsy results, preoperative serum calcium values, type of surgery, serum calcium values at postoperative 1st day and 1st month, postoperative hospital stay, drugs prescribed at discharge, histopathological diagnosis of the patient, and whether there was incidental parathyroidectomy or not were included. Results: Mean age of 371 patients who underwent thyroidectomy was 49 (19-82) years. Total thyroidectomy was the most common type of thyroidectomy with 61% (n= 225) of the patients. There was a significant decrease in pre- op and post-op calcium values in all three types of surgery performed on the patients, and there was no significant difference between the different types of surgery. Post-operative day one and month one serum calcium values were significantly increased in all groups (p=.000). The increase in post-op serum calcium level was most common in the group using calcium carbonate + cholecalciferol + calcitriol. Conclusion: The use of post-op calcitriol in patients undergoing thyroidectomy seems to be quite effective in preventing the development of hypocalcemia.

Introduction Data regarding the possible role of heparanase (HPA) in the occurrence of left atrial/left atrial appendage (LA/LAA) thrombus in patients with atrial fibrillation (AF) is lacking. The goal of the present study was to assess the association between plasma levels of HPA and LA/LAA thrombus in AF. Methods A total of 687 patients with nonvalvular AF (NVAF) without anticoagulation therapy were included from January 2016 to June 2019. Serum HPA analysis was performed with a commercially available human ELISA kit. Logistic regression models were used to test for association. Results Serum HPA levels were significantly higher in patients with LA/LAA thrombus than in those without LA/LAA thrombus (270.8 [193.4 +/- 353.2] pg/mL vs 150.3 [125.2 +/- 208.4] pg/mL; P < 0.001). In multivariate analysis, serum HPA remained a significantly independent predictor of LA/LAA thrombus (odds ratio 1.674, 95% confidence interval [CI] 1.339-2.289, P < 0.001). In the receiver operating characteristic (ROC) curve analysis, HPA showed a predictive value with an area under the curve (AUC) of 0.757 (95% CI 0.652-0.810, P < 0.001). The optimal cutoff level for HPA predicting LA/LAA thrombus was 210.7 pg/mL, with a sensitivity of 74.3% and a specificity of 64.8%. Conclusion An elevated HPA level was associated with the presence of LA/LAA thrombus in patients with AF. HPA might portend the risk for the prothrombotic state in AF patients.

In this study; the essential oils of flowers and leaves of P. elaeagnifolia plants were obtained by hydrodistillation method in a Clevenger type device. The chemical composition of volatile oils diluted with hexane were determined by analyzing with a GC-MS/FID instrument. The quantity of antioxidant activity of the obtained essential oils was determined by total phenolic content, free radical scavenging amounts, total flavonoid content, total antioxidant content, free radical scavenging capacity and ferric reducing antioxidant power capacity according to methods. Antimicrobial activity of essential oils was determined against 23 different microorganisms by disc diffusion method. As a result; essential oil yields in percentage are 0.44% and 0.72% in the flowers and leaves of the P. elaeagnifolia. Chemical classes with the highest percentage of compounds in essential oils of plant parts: Hydrocarbons (79.77%) and aldehydes (33.31%) were detected in the flowers and leaves of the P. elaeagnifolia. In addition, the main components found in essential oils are tricosane (36.98%-15.89%) in the flowers and leaves of the P. elaeagnifolia. The determination of antioxidant activity obtained from samples collected from plant parts was determined total phenolic substance amounts in the range of 48.57-68.32 mg GAE/100 mL, free radical scavenging amounts between 9.52-40.95 mg AA/100 mL, flavonoid substance amounts in the range of 1.34-3.95 mg QE/100 mL, total antioxidant amounts in the range of 66.93-185.10 mg AA/100 mL, free radical scavenging capacity between 23.40-81.02 mg AA/100 mL and FRAP capacity in the range of 4.20-10.50 mg FeSO4/100 mL. According to the results obtained with total phenolic content, free radical scavenging amounts, total flavonoid content, total antioxidant content, free radical scavenging capacity and ferric reducing antioxidant power capacity was determined the highest antioxidant properties in leaves of P. elaeagnifolia. According to the results of the antimicrobial activities analysis obtained from the collected samples of plant parts, it was determined that only the flowers of P. elaeagnifolia show antimicrobial activity against the microorganisms used.

Objective: To investigate the role, interest, and competence of the Turkish urologists for urologic surgeries which are also performed by the other surgeons. Materials and Methods: We conducted a 22-item online survey and invited urologists by e-mail. Questions were asked to evaluate the attitudes, performances, and capabilities of the urologists in surgeries which could be performed by the other surgeons. Results: A total of 305 responses were evaluated. The female incontinence surgery, pediatric urologic surgery, and adrenal surgery are mostly performed by the urologists in their hospitals. Turkish urologists mostly do not perform the following surgeries and interventions themselves and refer patients to the other surgeons for a percutaneous nephrostomy (47.2%), urinary diversions using the intestinal segments (44.9%), kidney transplantation (11.8%), and the transgender surgeries (7.2%). Almost half of the urologists do not perform adrenal surgeries (50.2%). Most urologists agree that they should be the main surgeons for all these surgeries. Conclusion: Urologists are no longer the main surgeons for some surgeries which are included on the urologic curriculum. Many urologists avoid performing the major urologic surgeries. Urology educators should familiarize the new urologists with all the urologic surgeries.

In the present study, four different ice creams were produced using cow, buffalo, goat, and sheep milk. The physicochemical, sensory properties and aroma profile analyzes of ice creams were carried out and the differences were evaluated. Dry matter rates of cow ice cream (CIC), goat ice cream (GIC), sheep ice cream (SIC) and buffalo ice cream (BIC) ranged from 27.96% to 30.51% and SIC had the highest content of dry matter (30.51%). Ash values of ice creams were determined between 0.61% and 0.75%. Titra-table acidity values varied between 0.11% and 0.18%. pH values of ice creams ranged from 6.49 to 7.04. Fat values of ice creams were determined between 4.05 (g/100g) and 5.10 (g/100g). The lowest overrun value (20.61%) was determined in SIC. The highest first dripping time (1980 s) and complete melting time (5970 s) were found in GIC. A total of 41 aroma compounds were determined by gas chromatography-mass spectrometry (GC-MS) and the BIC was the most aromatic product containing 36 aroma compounds. After the BIC, 15, 13 and 8 aroma compounds were detected in CIC, GIC and SIC, respectively. Additionally, aroma compounds 2-hexanone, 2-heptanone, limonene, 2-nonanone, 2-undecanone, 2-tridecanone, 2-pentadecanone were detected in all ice cream types. To evaluate the correlations between the aroma compounds, the principal component analysis (PCA) method was applied to ice cream samples and a strong positive relation was detected between CIC and GIC. In terms of sensory analysis, general acceptability properties were not statistically different (p>0.05) between all ice creams. SIC had the lowest flavor score and CIC had the highest one as sensory property.
