Özbek, Adem
Today, one of the main factors that increases the importance of sustainability and green finance is the scarcity of resources that meet needs. Sustainability has important benefits in reducing environmental erosion, such as acting as a carrier for the transportation of existing resources to future generations. Green finance is the use of financial resources in projects that embrace climate change aspects in the creation of a sustainable environment. At this point, banks, which are at the center of the financial system, are at a key point in terms of both maintaining sustainability and directing economic resources to the right areas. In the study, existing sustainability and green finance legislation studies in Turkey were followed. In addition, an attempt has been made to compile the studies carried out by banks operating in Turkey on sustainability and green finance. As a result of the study, it was seen that significant regulations were not made in credit policies in the banking system in Turkey, especially in terms of reducing environmental pollution. At the same time, it is seen that public banks include more sustainability and green financing in their policies than private and foreign capital banks.

Okan, Serdar
The purpose of this study is to examine customer satisfaction-related studies conducted between 2019 and 2021, focusing solely on articles, conference papers, and book chapters within the national literature context. The aim is to conduct a meta-analysis and analyze the existing dependent/independent variables related to customer satisfaction in terms of effect size, in order to establish a common consensus. After the screening process, 34 studies were included, and after determining the dependent/independent variables from these studies, a total of 7 different variables and 70 data points (k=70) were obtained, with a sample size (N) of 26,442. The collected data was subjected to meta-analysis using the Jamovi 1.6.23 program. Based on the findings, the variable with the highest effect size was customer loyalty with a value of 0.87, while empathy had the lowest effect size with a value of 0.55. The results indicate that the three variables with the largest effect sizes are customer loyalty, trust, and reliability, respectively. Based on this information, when customers trust and perceive a business as reliable, they engage in consuming its products/services, resulting in loyalty towards the business.

Objective: This study aims to investigate the effects of manipulation and mobilization treatments applied to the L3 segment on sportive performance to prevent performance anxiety and low performance resulting from competition stress in athletes. Material-Method: Sixty male volleyball players aged 18 to 25 were enrolled in this randomized controlled trial. Participants were randomly assigned to one of three groups: a manipulation, a mobilization, and a control group. After completing the required warm-up program, participants underwent either manipulation or mobilization based on their assigned group. Hip range of motion, lumbar range of motion, T-Test time (seconds), 10-meter sprint time (seconds), vertical jump height (cm), and horizontal jump distance (cm) were evaluated immediately before and after the interventions. Results: There were no significant differences between the groups regarding participants' age and height (p>0.05). The mobilization group had the highest mean body mass index and weight (p=0.05). In the intra-group analysis, statistically significant improvements were observed in the spinal manipulation group for hip external rotation, lumbar flexion, extension, T-test performance, and right lumbar flexion (p<0.05). In the mobilization group, significant changes were noticeable for right hip flexion, left hip abduction, hip external rotation, lumbar flexion, extension and lateral flexion, T-test performance, 10-meter sprint, and horizontal jump. Across all groups, all measures were statistically significant except for hip flexion, hip adduction, hip internal rotation, and lumbar lateral flexion (p<0.05). Conclusion: Comparing the data between the groups revealed that the spinal manipulation group demonstrated superior outcomes in right hip extension, right hip external rotation, lumbar flexion, extension, T-test performance, and 10-meter sprint times compared to the spinal mobilization and control groups. We believe that pre-competition spinal manipulation interventions may offer the greatest benefit for volleyball players.
- MakaleAçık Erişim2024A Study on The Relationship Between Organic Agriculture and Agricultural Employment in Türkiye
Merddan, Kurtuluş
Organic agriculture is a sustainable agricultural system with different principles that is carried out within the scope of certain rules. Due to the substitution of organic inputs with chemical inputs, getting the products ready for sale, weed control, and similar operations by hand, enterprises engaged in organic farming require a larger labor force. All these jobs increase employment opportunities in rural areas and allow small family businesses to continue production. In this study, it has been tried to reveal the relationship between organic agriculture and agricultural employment with the help of an econometric model and to determine the effect of organic agriculture on employment. The study analyzed a 17-year time series of data spanning from 2004 to 2021 to identify the factors influencing agricultural employment, taking into account various aspects of organic agriculture, including the number of organic agricultural products, the count of farmers engaged in organic agriculture, the area dedicated to organic agricultural production, the organic wild collection area, the total area allocated for organic agricultural production, the quantity of organic agricultural production, the number of entrepreneurs involved in organic agriculture, the unit price of subsidy for organic agriculture, and the total amount of subsidy provided to organic agriculture. Based on the results of the regression analysis, it was determined that the number of organic products does not have a significant effect on agricultural employment. In addition, it was found that the wild harvesting area is positively significant for agricultural employment and that the total production area of organic agriculture and the amount of subsidy are negatively significant. The results of the research reveal that a 1% increase in the wild harvesting area related to organic agriculture would lead to an increase of more than 0.28% in the agricultural employment rate, while a 1% increase in the total production area and the amount of subsidy would lead to a decrease of 0.40% and 0.44% in the agricultural employment rate, respectively.

Vural, Selvi
The aim of this study is to determine the impact of presenteeism on job performance. In the scope of the research, job performance has been examined in terms of both contextual and task performance. This study was conducted with the participation of personnel responsible for ground handling services in the aviation sector. Given the determined objective, it was deci-ded that the quantitative method is suitable for the research, and data were obtained through scale forms. To assess employees' presenteeism tendencies, the "Stanford Presenteeism Scale (SPS-6)" was utilized, while the "Job Performance Scale" was employed to measure job performance. The findings suggest that presenteeism impacts job performance in both task and con-textual dimensions. The results demonstrate that presenteeism significantly and positively affects both areas of job performance. This study highlights the beneficial effect of presenteeism on job performance. However, this significant positive relationship between presenteeism and performance does not entirely eliminate the fact that presenteeism is seen as a problem in busi-nesses.

Şimşek, Ahmet Bahadır
Health systems assessment is critical to ensure the sustainability of health services. The interest of researchers in analysing health systems, which intensified during the pandemic, is motivated by the opportunity to identify weaknesses and propose changes. Health systems analyses provide valuable feedback for policy makers, especially in developing countries, which struggle with obstacles such as limited resources, financial constraints and deficiencies in health infrastructure. As a developing country, Türkiye has been striving to ensure equal access to health services through its health transformation programme. In the last decade, developments such as the increase in Syrian migrants and economic contraction have negatively affected this effort. This situation motivates the need to analyse the current situation in the Turkish health system and provide suggestions for improvement. The literature on the Turkish health system mostly focuses on broad health system indicators such as health service accessibility, efficiency, quality and user satisfaction. This study focuses on assessing the accessibility of health infrastructure resources. In the study, health infrastructure indicators related to the Turkish health system are evaluated on a province basis for the period from 2012 to 2021. The evaluation is based on the descriptive statistics of the dataset and the province-based health index. The findings show changing trends and gaps in access to health services with the increase in population in the period 2012-2021. Some variables (e.g. population per hospital and population per bed) show low variances, while others (e.g. population per intensive care bed) show large differences. These differences may indicate unequal development and investment in health infrastructure. For policy makers, they emphasise the need to develop policies to address these inequalities and to distribute resources equitably. Analysing the health index values shows inequalities in access to health resources in different provinces of Türkiye as a score. In particular, while some provinces such as Isparta and Bolu stand out with consistently high index scores, lower index scores in other provinces such as Şanlıurfa, Mardin, Ağrı and Şırnak indicate that inequalities in access to health services are faced. This index identifies changes and gaps in the distribution of health resources and shows policy makers priority areas for intervention.

The aim of the study is an experimental study on football coaches' psychological well-being, psychological resilience, burnout levels and the relationship between them. The sample of this research, which used a descriptive research design, consisted of 146 football coaches. The data were obtained by applying the 'Psychological Well-Being Scale', 'Maslach Burnout Scale' and 'Connor-Davidson Psychological Resilience Scale'. 146 coaches from Denizli, Ankara and Izmir amateur football leagues participated in the study in 2019. Data regarding the applied scales were analyzed in the SPSS 18 program. It was determined that the psychological well-being, psychological resilience and burnout levels of football coaches were statistically moderate. However, the level of psychological resilience was found to be a significant predictor of burnout and psychological well-being levels. According to the results of the study, football coaches have a statistically moderate burnout, psychological resilience and psychological well-being capacity. Based on the information obtained from the face-to-face interview, it was determined that they felt highly exhausted/powerless. As a result, the study is valuable as it reveals that football coaches are highly affected by the lives of their athletes and that they need support to overcome the psychosocial problems they experience.
AtıfOpenAlex2İncele - MakaleAçık Erişim2024A Simplified Inventory Classification Approach: Combining Multiple Criteria Using the BORDA Method
Şimşek, Ahmet Bahadır
Traditional inventory classification approaches, such as ABC (Always Better Control), VED (Vital-Essential-Desirable), and their matrix forms, typically account for a limited range of inventory characteristics. Techniques like multi-criteria decision analysis, linear programming, and heuristic algorithms, which can consider more characteristics, require technical knowledge and expertise. However, the majority of small and medium-sized enterprises (SMEs) lack the staff capable of applying these methods. Therefore, a method that can accommodate numerous characteristics and is easy to use is necessary. This paper introduces a classification approach that combines multiple inventory characteristics using the BORDA method, specifically designed to assist SME managers with limited technical expertise. A dataset containing 47 stock keeping units (SKUs), including the average cost, annual cost, and lead time characteristics, is used to demonstrate the application of the proposed approach. The implementation reveals that the BORDA method provides a comprehensive and unbiased solution to inventory classification by systematically combining the rankings of various inventory characteristics. This approach simplifies the classification process by integrating multiple characteristics in a straightforward manner, making it particularly suitable for SMEs.

Aktas, Songul; Ay, Ozge Palanci
Breastfeeding is an important period in terms of mother and baby health. In order to benefit from breast milk at the maximum level during the breastfeeding process, it is important for the mother to start breastfeeding as soon as possible after birth and to be able to maintain breastfeeding. In this process, physiological, psychological, social and motivational factors have an effect on the continuity and maintenance of breastfeeding. If the mother experiences any breastfeeding problem during breastfeeding, her motivation to breastfeed may decrease. In recent studies, breastfeeding trainings have been applied with different techniques to encourage mothers to breastfeed during the breastfeeding process, to support them to feel competent and strong in this process and to increase their motivation for breastfeeding, adapted to their individual needs. One of these techniques is the motivational interview technique. Motivational interviewing technique has a supportive role in helping mothers to adapt to the breastfeeding process, to determine their attitudes towards breastfeeding, to address their lack of knowledge about breastfeeding, their concerns about this process, to increase their confidence and intrinsic motivation about breastfeeding, and to continue breastfeeding by helping behaviour change when necessary. In this article, the importance of motivational interviewing technique in providing breastfeeding motivation in the postnatal period is explained.

Celen, Pinar; Erdem, Hasan Hüseyin
In this paper, a coal (lignite) fired thermal power plant having capacity of 160 MW is taken into consideration and the impact of condenser pressure, moisture content of lignite, excess air coefficient, the efficiency of turbine pressure and heater numbers on power plant thermal efficiency is investigated. It is aimed to determine the performance losses of each equipment by means of thermodynamics and economic analysis. In this scope, it is expected that the power plant operator will be able to evaluate the reduction potential of equipment performance losses and ensure more effective use of the power plants by correctly planning the maintenance and rehabilitation needs and time. In the calculations, the boiler efficiency was determined with EN 12952-15 standard (indirect method) since this method has higher accuracy in coal-fired boilers. It is seen that the condenser pressure and excess air coefficient increments have no significant impact on power plant efficiency compared to moisture content of lignite, excess air coefficient, efficiency of turbine pressure and heater numbers. The significant effect is observed for fuel moisture content which rises from 22% to 47% and the power plant efficiency falls from 40% to 28%. The variation of the power plant thermal efficiency in case of failure of heaters is investigated and the power plant efficiency has decreased from 40.17% to 36.09% when the pre-heaters are no longer in to be in use because of any reason. In addition, revenue losses are estimated for each main equipment efficiency reduction for better use of power plant capacities and electricity lowering production costs.

Aim: Osteoarthritis (OA) is a chronic, degenerative joint disease that is characterised by joint pain and stiffness. The development of kinesiophobia is common in OA patients, especially related to pain and loss of function. The aim of our study was to determine the relationship between kinesiophobia and pain, quality of life and physical functions in patients with knee OA. Material and Method: A total of 60 patients (30 females and 30 males, aged 40-65 years) diagnosed with Kellgren-Lawrence (KL) grade 2 and 3 OA participated in this cross-sectional study. Tampa Scale for Kinesiophobia (TSK), Short Form Health Survey (SF-12), Visual Analogue Scale (VAS), Knee Injury and Osteoarthritis Outcome Score Physical Function Short Form (KOOS-PS), Oxford Knee Score (OKS), Lower Extremity Functional Scale (LEFS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Berg Balance Scale (BBS) scales and Timed Up and Go (TUG), 6-Minute Walking Test (6MWT), The Five Repetition Sit to Stand Test (5STS) and Stair-Climbing Test (SCT) functional tests were performed. Results: A statistically significant difference was observed between the male and female groups in all scales and functional test results, with the exception of TSK (p<0.05). A positive correlation was found between kinesiophobia and SCT in the female group, while a negative correlation was found between TUG and SF-12 PCS in the male group (p<0.05). Conclusion: The findings indicated that, in general, kinesiophobia was not significantly correlated with pain, knee score, balance, quality of life and functional tests in male and female OA patients. However, some scales and tests showed positive and negative correlations with kinesiophobia in both groups, although limited.

This study aimed to determine the differences in pain, quality of life and functional status of individuals with Knee Osteoarthritis (KOA) between grades. The study included 90 patients with different grades (Grades 1, 2, and 3) of KOA. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lower Extremity Functional Scale (LEFS), Berg Balance Scale (BBS), Knee Injury and Osteoarthritis Outcome Score-Physical Function Shortform (KOOS-PS), Short Form Health (SF-12), Oxford Knee Score (OKS) and Visual Analogue Scale (VAS) scales were applied. Timed Up and Go test (TUG), Five Times Sit to Stand Test (5STS), Stair Climb Test (SCT), 6-minute Walking Test (6MWT) and proprioception measurements were performed for functional assessments. Foot Posture Index (FPI-6), Navicular Drop Test (NDT) and Foot Function Index (FFI) tests were used for foot posture evaluations. In the functional tests performed in the study, a significant decrease in test performance was observed in the 6MWT and SCT tests as the grade level increased (P<0.05). In TUG and 5STS tests, a significant decrease in performance was detected only in Grade 3 compared to other grades (P<0.05). Similarly, there were significant differences between the grades in all scales applied (P<0.05). In proprioception evaluations, similar medians were found between sides (P>0.05). In FFI averages, significant differences were found especially in pain (P=0.036) and insufficiency (P=0.008) parameters compared to grade 3. This study revealed noticeable differences in knee scores, pain, quality of life scales and functional tests at different stages of KOA. These differences were generally negative as grade levels increased. However, consistent with previous research, conflicting results were identified, emphasizing the need for a nuanced understanding of KOA.

1970’lerdeki petrol krizinden sonra, petrol fiyatlarının ekonomi üzerine etkileri konusundaki tartışmalar hız kazandı. Petrol tükenebilir bir enerji kaynağı olmasının yanında ortaya çıkardığı çevre kirliliği birçok gelişmiş ülkeyi yenilenebilir enerji kaynaklarına yöneltmiştir. Ayrıca Petrol fiyatlarındaki dalgalanmalar ve dışa bağımlılığı arttırması ülke ekonomileri için istikrar bozucu etkiler doğurmaktadır. Bütün bunlar petrol rezervi bulunan ve ekonomileri büyük ölçüde petrol sanayiine bağlı olan ülkeler için tehdit unsuru oluşturmaktadır. Bu çalışmada toplam petrol üretimi ve tüketimi Avrupa’dan daha fazla olan ve önceki çalışmalarda genellikle fazla odaklanmayan Rusya, Azerbaycan ve Endonezya’da petrol fiyatları, ihracat ve döviz kuru arasındaki ilişkiyi incelemiştir. Panel nedensellik testlerinin kullanıldığı çalışma 1996-2021 dönemini kapsamaktadır. Analiz sonuçları ilgili ülkelerde petrol fiyatlarından ihracat ve döviz kuruna tek yönlü bir nedensellik ilişkisinin olduğunu göstermektedir. Ayrıca, ihracattan döviz kuruna doğru tek yönlü bir nedensellik ilişkisi olduğunu tespit edilmiştir.
