| 1 | Fintech investments in European banks:a hybrid IT2 fuzzy multidimensional decision‑making approach显示文摘Financial technology(Fintech)makes a significant contribution to the financial system by reducing costs,providing higher quality services and increasing customer satisfaction.Hence,new studies play an essential role to improve Fintech investments.This study evaluates Fintech-based investments of European banking services with an application of an original methodology that considers interval type-2(IT2)fuzzy decision-making trial and evaluation laboratory and IT2 fuzzy TOPSIS models.Empirical findings are controlled for consistency by applying the VIKOR method.Moreover,we conduct a sensitivity analysis by considering six distinct cases.This study contributes to the existing literature by identifying the most important Fintech-based investment alternatives to improve the financial performance of European banks.Our empirical findings illustrate that results are coherent,reliable,and identify“competitive advantage”as the most important factor among Fintech-based determinants.Moreover,“payment and money transferring systems”are the most important Fintech-based investment alternatives.It is recommended that,among Fintech-based investments,European banks should mainly focus on payment and money transferring alternatives to attract the attention of customers and satisfy their expectations.This is also believed to have a positive impact on the ease of bank’receivable collection.Another important point is that Fintech-based investments in money transferring systems could help to decrease costs. | Gang Kou Ozlem Olgu Akdeniz Hasan Dincer Serhat Yuksel | 2021 | Financial Innovation2021，7，1： | 38 |
| 2 | Diabetes and cardiac autonomic neuropathy: Clinical manifestations, cardiovascular consequences, diagnosis and treatment显示文摘Cardiac autonomic neuropathy(CAN) is a frequent chronic complication of diabetes mellitus with potentially life-threatening outcomes. CAN is caused by the impairment of the autonomic nerve fibers regulating heart rate, cardiac output, myocardial contractility, cardiac electrophysiology and blood vessel constriction anddilatation. It causes a wide range of cardiac disorders, including resting tachycardia, arrhythmias, intraoperative cardiovascular instability, asymptomatic myocardial ischemia and infarction and increased rate of mortality after myocardial infarction. Etiological factors associated with autonomic neuropathy include insufficient glycemic control, a longer period since the onset of diabetes, increased age, female sex and greater body mass index. The most commonly used methods for the diagnosis of CAN are based upon the assessment of heart rate variability(the physiological variation in the time interval between heartbeats), as it is one of the first findings in both clinically asymptomatic and symptomatic patients. Clinical symptoms associated with CAN generally occur late in the disease process and include early fatigue and exhaustion during exercise, orthostatic hypotension, dizziness, presyncope and syncope. Treatment is based on early diagnosis, life style changes, optimization of glycemic control and management of cardiovascular risk factors. Medical therapies, including aldose reductase inhibitors, angiotensin-converting enzyme inhibitors, prostoglandin analogs and alpha-lipoic acid, have been found to be effective in randomized controlled trials. The following article includes the epidemiology, clinical findings and cardiovascular consequences, diagnosis, and approaches to prevention and treatment of CAN. | Akif Serhat Balc?o?lu Haldun Müderriso?lu | 2015 | World Journal of Diabetes2015，6，1： | 22 |
| 3 | Prevalence of gastroesophageal reflux disease in a country with a high occurrence of Helicobacter pylori显示文摘AIM To evaluate the prevalence of gastroesophageal reflux disease(GERD) with additional symptoms, relationship with Helicobacter pylori(H. pylori) of this country-wide study.METHODS Data from 3214 adults were obtained with validated questionnaire. Eight hundred and forty-one subjects were randomized to be tested for H. pylori via the urea breath test. 'Frequent symptoms' were defined heartburn and/or regurgitation occurring at least weekly.RESULTS The prevalence of GERD was 22.8%, frequent and occasional heartburn were 9.3%-12.7%, regurgitation were 16.6%-18.7%, respectively. Body mass index(BMI) ≤ 18.5 showed a prevalence of 15%, BMI > 30 was 28.5%. The GERD prevalence was higher in women(26.2%) than men(18.9%)(P < 0001). Overall prevalence of H. pylori was 75.7%. The prevalence was 77.1% in subjects without symptoms vs 71.4% in subjects with GERD(χ~2 = 2.6, P = 0.27). Underprivileged with the lowest income people exhibit a higher risk.CONCLUSION GERD is common in Turkey which reflects both Western and Eastern lifestyles with high rate of H. pylori. The presence of H. pylori had no effect on either the prevalence or the symptom profile of GERD. Subjects showing classical symptoms occasionally exhibit more additional symptoms compared with those without classical symptoms. | Serhat Bor Gul Kitapcioglu Elmas Kasap | 2017 | World Journal of Gastroenterology2017，23，3： | 8 |
| 4 | Recurrent carpal tunnel syndrome: Evaluation and treatment of the possible causes显示文摘AIM To investigate the causes of the recurrent carpal tunnel syndrome(CTS) and implemented surgical interventions.METHODS Four hundred and eighty-seven patients, who were diagnosed with CTS and underwent surgical intervention between October 2016 and September 2007, were evaluated in this retrospective study. The age, gender, physical evaluation findings, electrophysiological examination reports and implemented surgical treatment methods were analyzed.RESULTS Thirty-nine of the cases were operated due to recurrent CTS. Further examination of the patients with recurrent CTS revealed that ten cases had diabetic polyneuropathy, three cases had hypothyroidism, two cases had rheumatoid arthritis and one case had systemic amyloidosis. Postoperative electromyography confirmed the neuropathy was due to systemic diseases. The remaining 23 patients with recurrent CTS did not have any systemic disease and all of them had applied previously to another health center. CONCLUSION We concluded that the recurrence rates in CTS might be decreased with exploration and incision of the entire transverse ligament. Damage to the motor and sensory branches of the median nerve could be avoided with an incision on the ulnar side. | Ahmet Ero?lu Enes Sar? Ali K?van?

| 5 | Balanced scorecard-based analysis of customer expectations for cosmetology services:a hybrid decision modeling approach显示文摘The goal of this study is to analyze and characterize customer expectations in the cosmetics sector.Within this framework,first,the extant literature is reviewed,and 12 most prominent performance measurement criteria are identified.Then,these criteria are organized along the four different balanced scorecard dimensions.By employing an Interval Type-2 Fuzzy DEMATEL methodology,the weighted importance of these dimensions and criteria are identified.Additionally,with the Interval Type-2 Fuzzy TOPSIS approach,13 leading cosmetic service providers in Ukraine are ranked based on their relative scores.The findings of the study indicate that consumer is the most significant dimension while learning and growth seem to have the least importance.Similarly,it is also concluded that all consumerfocused criteria(i.e.diversification of services,feedback on the product and services,and customer loyalty)have the highest priorities in the complete criterion set. | Dursun Delen Oleksandr Dorokhov Liudmyla Dorokhova Hasan Dincer Serhat Yüksel | 2020 | Journal of Management Analytics2020，7，4： | 3 |
| 6 | A hybrid heterogeneous Pythagorean fuzzy group decision modelling for crowdfunding development process pathways of fintech‑based clean energy investment projects显示文摘This study aims to evaluate the crowdfunding alternatives regarding new service development process pathways of clean energy investment projects.In this framework,a new model has been generated by considering the consensus-based group decisionmaking with incomplete preferences,Pythagorean fuzzy decision-making trial and evaluation laboratory(DEMATEL)and technique for order preference by similarity to ideal solution(TOPSIS).Moreover,a comparative evaluation has been performed with Vise Kriterijumska Optimizacija I.Kompromisno Resenje methodology and sensitivity analysis has been made by considering 4 different cases.The main contribution is to identify appropriate crowdfunding-based funding alternatives for the improvement of the clean energy investments with a novel MCDM model.By considering the iteration technique and consensus-based analysis,the missing parts in the evaluations can be completed and opposite opinion problems can be reduced.Furthermore,with the help of hybrid MCDM model by combining DEMATEL and TOPSIS,more objective results can be reached.It is concluded that the analysis results are coherent and reliable.The findings indicate that the full launch is the most significant criterion for equity and debt-based crowdfunding alternatives.On the other side,the analysis has the highest weight for reward and donation-based alternatives whereas design is the most essential item regarding the royalty-based alternative.Additionally,it is also defined that equity-based crowdfunding alternative is the most significant for the service development process of clean energy investment projects.In this way,it will be possible to provide a continuous resource for clean energy investment projects.On the other hand,by providing financing with equity,there will be no fixed financing cost for clean energy investors.If these investors make a profit,they distribute dividends with the decision of their authorized bodies. | Yue Meng Haoyue Wu Wenjing Zhao Wenkuan Chen Hasan Dincer Serhat Yuksel | 2021 | Financial Innovation2021，7，1： | 2 |
| 7 | Investigation of carbon contamination in lost foam castings of low carbon steel显示文摘Lost foam casting(LFC) process is a special casting method in which polymeric foam patterns with refractory coatings are utilized as a mould component. In this work, four types of foam: expandable polyethylene(EPE), expandable polypropylene(EPP) and expandable polystyrene(EPS) foams with two different densities were employed as pattern materials. LFC and conventional green sand mould casting methods were used to cast a low carbon steel, A216 Grade WCB. Both casting processes were carried out at 1,580 °C. Chemical analysis results showed that the carbon contamination level was high and was influenced by pattern type. Metallographic investigations revealed a significant increase in the percentage of pearlite phase in all LFC samples. Densities of manufactured samples were calculated in order to evaluate porosity of the products. It was determined that the densities of the LFC samples were lower than the green sand mould cast reference sample(RS). Vickers hardness tests were also carried out and increments in hardness values with increased carbon content was observed. | Oznur Kilic Serhat Acar Alptekin Kisasoz Kerem Altug Guler | 2018 | China Foundry2018，15，5： | 2 |
