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.

Çelik, Orkun
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.

Objective: To compare the clinical preferences of urologists in prostate cancer screening and diagnosis with current guideline recommendations.Materials and Methods: The study is based on an online survey that consists of 21 single response or multiple response questions. By e-mail, 2,305 certified urologists in active practice as well as urology residents in their last year of training were invited to participate in the study. Descriptive statistics were used to analyze practice patterns and demographics. The respondents were divided into groups based on their experience in urology, hospital type and academic title.Results: Our results show that preferences of the majority of urologists conflicts with recommendations of European Association of Urology Prostate Cancer Guidelines regarding prostate biopsy method, management of a patient with high prostate-specific antigen value, use of additional test and performance scoring systems, role of multiparametric prostate magnetic resonance imaging.Conclusion: Urologists act in the direction of their habits or clinical experience rather than current guidelines regardless of their experience. Both clinicians and professional organizations should work on what can be done about the reflection of rapidly changing scientific knowledge on the field and the improvement of the health service provided.

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.

Gumushane region in Turkey is rich in plant diversity. The flowers and leaves of Pyrus elaeagnifolia Pall. plants that will form the basis of this research were collected from the places determined. 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.

Sahin, Ceyda Uzun; Aydin, Merve; Kulakaç, Nursen
BACKGROUND/AIMS: The global coronavirus disease (COVID-19) pandemic affects society seriously in terms of psychosocial aspects, but this effect is more intense on some specific population groups. University students are among the most affected population groups by the pandemic. This study was conducted to determine the anxiety, motivation, stress levels, and associated factors among health science students during the COVID-19 pandemic. MATERIALS AND METHODS: The population of this descriptive and cross-sectional study consisted of students studying at health-related departments in three universities in Turkey. The data were collected from 855 students determined by the stratified sampling method using the online survey method. A questionnaire developed by the researchers and the Beck Anxiety Inventory (BAI) were used to collect the data. Percentage, mean, standard deviation, t-test, One-Way ANOVA test, Pearson correlation, and linear regression analysis were performed to evaluate the data. RESULTS: The results revealed that the mean age of the students was 20.85 +/- 2.37 years (min: 18; max: 41), 80.5% were women, 38.0% were nursing students, 13.7% had a family member with the diagnosis of COVID-19. The BAI mean score was found to be 29.00 +/- 7.8. According to the multiple linear regression analysis, the factors affecting students' anxiety scores significantly were being female, impaired sleep and nutrition patterns, decreased motivation, increased stress level and having a family member with the diagnosis of COVID-19. CONCLUSION: Health science students experience severe anxiety due to COVID-19 pandemic and have moderate motivation and stress scores. Being a woman, having impaired sleep and nutrition patterns, reduced motivation, increased stress level and a family member diagnosed with COVID-19 are factors influencing the level of anxiety.

AtıfWoS5İncele - MakaleAçık Erişim2022The cultural practice of decluttering as household work and its potentials for sustainable consumption
Muster, Viola; Iran, Samira; Muensch, Marlene
Popular literature and guidebooks on minimalism and decluttering have brought the idea of less is more into the mainstream. Although decluttering constitutes a central household chore in consumer societies, it is rarely communicated as work within the current popular minimalism discourse, but rather as an expression of self-care. Whether and to what extent this lifestyle minimalism can contribute to sustainable consumption has - with a few exceptions - not yet been studied in detail. In this article, decluttering is first conceptualized in between housework and self-care. Based on this work, potentials and limits for the promotion of sustainable consumption are outlined. Finally, initial insights from an ongoing citizen science project on decluttering in Germany are presented. The qualitative results from two workshops and two reflection exercises show that the main motivation for participants is the dissatisfaction with their multitude of possessions and the desire for fewer material possessions in the future. The decision to declutter can be understood as a window of opportunity in which individuals are willing to reflect on and realign their possessions and desires for goods. Thus, we argue that decluttering can be a relevant starting point for changing consumption behavior toward (more) sustainable consumption. At the same time, it remains unclear whether and to what extent the participants' willingness to change regarding possessions and consumption actually leads to more sustainable consumption behavior after decluttering. It is even conceivable that the newly gained space will stimulate additional consumption. Decluttering would then rather function as a catalyst for further consumption (and would have no or rather a negative contribution to sustainability goals). Further research is needed to shed light on this.

Sahin, Huseyin; Kose, Oguz; Oktay, Tugrul
Purpose This study aims to optimize autonomous performance (i.e. both longitudinal and lateral) and endurance of the quadrotor type aerial vehicle simultaneously depending on the autopilot gain coefficients and battery weight. Design/methodology/approach Quadrotor design processes are critical to performance. Unmanned aerial vehicle durability is an important performance parameter. One of the factors affecting durability is the battery. Battery weight, energy capacity and discharge rate are important design parameters of the battery. In this study, proper autopilot gain coefficients and battery weight are obtained by using a stochastic optimization method named as simultaneous perturbation stochastic approximation (SPSA). Because there is no direct correlation between battery weight and battery energy density, artificial neural network (ANN) is benefited to obtain battery energy density corresponding to resulted battery weight found from SPSA algorithm. By using the SPSA algorithm optimum performance index is obtained, then obtained data is used for longitudinal and lateral autonomous flight simulations. Findings With SPSA, the best proportional integrator and derivative (PID) coefficients and battery weight, energy efficiency and endurance were obtained in case of morphing. Research limitations/implications It takes a long time to find the most suitable battery values depending on quadrotor endurance. However, this situation can be overcome with the proposed SPSA. Practical implications It is very useful to determine quadrotor endurance, PID coefficients and morphing rate using the optimization method. Social implications Determining quadrotor endurance, PID coefficients and morphing rate using the optimization method provides advantages in terms of time, cost and practicality. Originality/value The proposed method improves quadrotor endurance. In addition, with the SPSA optimization method and ANN, the parameters required for endurance will be obtained faster and more securely. In addition, the energy density according to the battery weight also contributes to the clean environment and energy efficiency.

Objective: The etiology of Threatened Abortion is not clearly known. One of the hypotheses thought to play a role in the pathophysiology of threatened abortion is that bleeding occurring in threatened abortion causes the development of a chronic inflammatory reaction in the decidua. Because of this hypothesis, we aimed to evaluate the relationship between a threatened abortion and inflammatory markers procalcitonin, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). Methods: This is a prospective, controlled study. Serum procalcitonin, neutrophil-lymphocyte ratio and platelet-lymphocyte ratio of 55 pregnant women diagnosed with threatened abortion were compared with the results of 55 healthy pregnant women. ROC analysis of procalcitonin, NLR and PLR was performed for threatened abortions. Results: Procalcitonin and NLR levels were significantly higher in the threatened abortions group than in the control group (p < 0.05). The area under the curve (AUC) in ROC analysis was within the 95% confidence interval for procalcitonin and NLR, both of which were statistically significant (p < 0.05). Procalcitonin and NLR resulted as appropriate parameters as diagnostic decision-makers in predicting threatened abortions. Conclusion: There is an association between procalcitonin and NLR and threatened abortion. This result may support that inflammatory reaction plays a role in the etiology of threatened abortion.
