İşletmeler, bulunduğu belirlilik ve belirsizlik ortamlarında nitelikli bir nihai karar verebilmek için birden fazla kriteri göz önünde bulunduran çeşitli Çok Kriterli Karar Verme (ÇKKV) yöntemlerini uygulanmışlardır. Karar verme sürecinde ÇKKV yöntemleri, Karar Verici'nin (KV) birden fazla kriter kullanmasına izin vererek en iyi alternatifin seçilmesinde, alternatiflerin en iyiden en kötüye sıralanmasında veya benzer özellikleri ve davranışları gösteren alternatiflerin sınıflandırılmasında kolaylık sağlamaktadır. Gelişen teknoloji ile birlikte ekonomilerin rekabet gücü de artmaktadır. Ekonomiler rekabet gücünü artırmak için küçük ve orta büyüklükteki işletmelerin kuruluşlarını ve faaliyetlerini kolaylaştırmak amacıyla ciddi düzenlemeler yapmışlardır. Dünya Bankası Grubu ve Uluslararası Finans Kurumu, kolaylaştırıcı bir iş ortamını sağlayacak iş düzenlemeleri ve yasal sistemleri incelemek amacıyla İş Yapma Kolaylığı Endeksi'ni (İŞYKE) oluşturmuşlardır. Bu endeks, 189 ülke ekonomisini, iş yapmak için uygun ortama sahip olma kriterlerine göre sıralamaktadır. Çok kriterli bir yapıya sahip olan İŞYKE belirsiz, kesin olmayan ve tutarsız kriterler içerdiğinden, bu çalışmada ÇKKV yöntemlerinden ELECTRE III ve ELECTRE TRI yöntemleri bu sorunu çözmede uygun yöntemler olarak seçilmiştir. Çeşitli eşik değerleri işleme katan bu yöntemler, ülke ekonomilerini iş yapma kolaylığı açısından sıralamak (ELECTRE III) ve sınıflandırmak (ELECTRE TRI) için kullanılmıştır. Her iki yöntemin elde ettiği sonuçların güvenirliğini test etmek ve başlangıç parametre değerlerinin iyi kurulup kurulmadığını bulmak için, yöntemlerin değişik parametrelerine duyarlılık analizi yapılmıştır. Bu duyarlılık analizinin sonuçları gerçek veriler ile karşılaştırılmıştır. Ayrıca, literatürde çok kullanılan ÇKKV yöntemlerinde biri olan TOPSİS yöntemi, ELECTRE III yönteminin güvenirliğini test etmek için bu çalışmada kullanılmıştır. Literatürde genellikle ELECTRE TRI yönteminin kötümser atama kuralıyla yapılan sınıflandırması göz önünde bulundurulurken, bu çalışmada yöntemin hem iyimser, hem de kötümser atama kuralları göz önünde bulundurularak her iki atama kuralının karşılaştırılması amaçlanmıştır. Elde edilen sonuçlara göre, gerçek veriler ile karşılaştırıldığında ELECTRE III yönteminin ülkeleri iş yapma kolaylığı açısından sıralamada iyi bir performans gösterdiği, TOPSİS yönteminin ise aynı performansı göstermediği belirlenmiştir. ELECTRE TRI yöntemi ile hem iyimser hem de kötümser atama kuralı kullanılarak yapılan sınıflandırmada, gerçek veriler ile karşılaştırıldığında her iki atama kuralının birbirine çok yakın sonuçlar elde ettiği görülmüştür. Fakat iyimser atama kuralı ile elde edilen sonuçların gerçek sınıflandırmanın sonuçları ile biraz daha uyumlu olduğu sonucuna varılmıştır. Ayrıca, ülkelerin iş yapma kolaylığı gelir seviyeleriyle karşılaştırıldığında, ülkelerin gelir seviyelerinin iş yapma ortamlarını etkilediği görülmüştür.

In order to make a qualified final decision in the certainty and uncertainty environments, enterprises have applied various Multi-Criteria Decision Making (MCDM) methods that take into consideration multiple criteria. In the decision-making process, MCDM methods allow the Decision Maker (DM) to use more than one criteria, allowing the selection of the best alternative, the ranking of alternatives from the best to the worst, or the classification of alternatives that show similar characteristics and behaviors. With the developing technology, the competitiveness of economies also increases. Economies have made serious arrangements to facilitate the establishment and activities of small and medium-sized enterprises to increase their competitiveness. The World Bank group and the International Finance Corporation created the Ease of Doing Business Index (EDBI) to examine regulatory and legal systems that will facilitate a facilitating business environment. This index ranks 189 countries' economies according to the criteria for having a suitable environment for doing business. Since EDBI, which has a multi-criteria structure, contains imprecise, uncertain and inconsistent criteria, in this study, MCDM methods ELECTRE III and ELECTRE TRI have been chosen as appropriate methods to solve this problem. These methods, which incorporate various thresholds, have been used to rank (ELECTRE III) and sort (ELECTRE TRI) the economies of the country in terms of ease of doing business. In order to test the reliability of the results obtained by both methods and to find out whether the initial parameter values are well established, sensitivity analysis was performed to different parameters of the methods. In addition, TOPSIS method which is one of the most widely used MCDM methods in literature is used in this study to test the reliability of ELECTRE III method. While generally considering the sorting of ELECTRE TRI method with pessimistic assignment rule in the literature, this study aimed to compare both assignment rules by taking into account both optimistic and pessimistic assignment rules. According to the results, when compared with the actual data, it was determined that ELECTRE III method performed well in ranking countries in terms of ease of doing business, whereas TOPSIS method did not show the same performance. As a result of the sensitivity analysis, very close to the actual data were obtained. As a result of the sorting made using both the optimistic and pessimistic assignment rule of ELECTRE TRI method, it was seen that both assignment rules had very close results when compared with the actual data. However, it was concluded that the results obtained by the optimistic assignment rule were slightly more consistent with the results of the actual sorting. Moreover, when the ease of doing business of the countries is compared with their income levels, it is seen that the income levels of the countries affect the business environment.

In this study, the clinical findings, organ involvements, similarities, and differences in laboratory and imaging of the children with MIS-C and KD at the time of admission will be revealed in detail, and the treatment methods and follow-up results will be revealed. Material and method Our study was a single-center study and included pediatric patients who were treated with a diagnosis of MIS-C between March 2020 and July 2023 in the pediatric cardiology, pediatric emergency, pediatric infection, and pediatric intensive care clinics at Celal Bayar University and who were treated with a diagnosis of KD (complete/incomplete) between January 2015 and July 2023. MIS-C diagnosis was made according to the Turkish Ministry of Health COVID-19 guidelines. Sociodemographic characteristics, clinical, laboratory, and echocardiography findings, treatments given, and clinical course of all patients included in the study were evaluated. Results The median age was 30 months (7–84) in KD and 96 months (6-204) in MIS-C, and it was significantly higher in the MIS-C group (p = 0.000). Symptom duration was significantly longer in the MIS-C group (p = 0.000). In terms of clinical features, gastrointestinal syndrome findings (nausea, vomiting, abdominal pain) and respiratory findings (dyspnea) were significantly higher in the MIS-C group (p = 0.007, p = 0.000, p = 0.002, respectively). Regarding cardiovascular system involvement, coronary involvement was significantly higher in the KD group. However, valvular involvement, left ventricular systolic dysfunction, and pericardial effusion were significantly higher in the MIS-C group (p = 0.000, p = 0.001, p = 0.003, p = 0.023, respectively). In terms of laboratory findings, white blood cell count was higher in KD (p = 0.000), absolute lymphocyte count, platelet level, blood sodium, and albumin levels were lower in MIS-C group (p = 0.000, p = 0.000, p = 0.000, p = 0.000, p = 0.003, respectively), ferritin and troponin levels were significantly higher in MIS-C group. These results were statistically significant (p = 0.000, p = 0.000, respectively). D-dimer and fibrinogen levels were high in both groups, and no significant statistical difference was detected between the two groups. There was no significant difference between the two groups regarding the length of hospitalization and mortality, but steroid use was significantly higher in the MIS-C group (p = 0.000). Conclusion In conclusion, this study has demonstrated the similarities and differences between MIS-C and KD regarding clinical findings, organ involvement, and laboratory and imaging results.

An oasis for alien benthic foraminifera in the Aegean Sea
No full textThe benthic foraminiferal fauna in Pamucak Cove (NW Kuşadasi, Turkey) was investigated. A rich foraminiferal assemblage was observed around submarine springs, which were located 200 m off the coast. This foraminiferal assemblage is typical Mediterranean. However, the abundance of alien species is noteworthy. Fourteen alien foraminifera were found. Indo-pacific originated species; Quinqueloculina sp. C, Triloculina sp. A, Pyramidulina catesbyi (d'Orbigny), Brizalina simpsoni (Heron-Allen and Earland) and Amphistegina lessonii d'Orbigny were observed for the first time on the Turkish coastline. Specimens of Haddonia sp. and Cymbaloporetta plana (Cushman), abundantly observed in SW Antalya and Nodopthalmidium antillarum (Cushman), previously recorded from Iskenderun were also found in the study area, these are the first records for these species in the Aegean Sea. In addition, seven individuals of Euthymonacha polita (Chapman) were found around the springs, and this constitutes the first record of this species in the entire Mediterranean Sea. © 2010 The Author(s)
