Distance metrics and their extensions are widely accepted tools in supporting distancebased decision making, consensus building, and preference aggregation systems. For several models of this nature, it may be necessary to elucidate the problem output in the original input domain. When a particular parameter of interest is desired to be produced in this original domain, i.e., the scale, the decision makers simply resort to constraints that function in parallel with this goal. However, there exist some cases where such a membership is guaranteed by the mathematical properties of the distance metric utilized. In this paper, we argue . . . that the scale constraints utilized in this manner under the distance-metric optimization framework are, in some cases, completely redundant. We provide necessary mathematical proofs and illustrate our arguments through an abstract physical system, examples, a case study, and a brief computational experiment Daha fazlası Daha az

In this manuscript, with grounding in Liu–Lin axioms of greyness degree and information content, we provide new results that relate to these concepts in consideration of a number of mathematical operations over a sequence of grey numbers. In particular, we derive greyness degree results of summation, conic combination, and convex combination of a sequence, as well as inverse of a number and normalization of a number over a sequence. Then, we turn our attention to prove information content results for the union and intersection of a sequence. We illustrate our results by using a simple Monte Carlo simulation in the multi-attribute de . . .cision-making context, and by using an interesting dice-rolling experiment. Through our analysis, we also provide some new definitions, such as for conic combination, convex combination, normalization, and union and intersection operations. The novelty of the derived results in this study is that they can help researchers and practitioners of grey systems in tracking probable intensifications and reductions in the greyness degree in successive application steps of their working methods. Moreover, researchers are provided with two results to calculate information content for the union and intersection of grey numbers in an uncomplicated manner Daha fazlası Daha az

Gerek günümüzün teknolojik gelişimi gerekse bilgiye kolay erişim, bireylerin hastalıkları hakkında bilgi sahibi olmalarını ve kendilerine neyin iyi geldiğini araştırabilmelerini sağlamaktadır. Ancak bireylerin sağlık hizmetine eirşimi için sağlık okuryazarlığı önemli bir yere sahiptir. Sağlık okur yazarlığı en geniş anlamda bireylerin tam iyilik hali için sağlığını koruma ve geliştirme amaçlı bilgi edinme, anlama ve kullanma yeteneğidir. Tüm insanları yakından ilgilendiren bu yetenek kadınları daha da çok etkilemektedir. Keza kadın sağlığı hem kendisini hem de ailesini etkilemektedir. Sağlık okuryazarlığı pek çok faktörden etkilemek . . .tedir ve demografik özellikler bu faktörlerin başında yer almaktadır. Bu bilgiler ışığında çalışmanın amacı kadınların eğitim düzeyinin sağlık okuryazarlığına etkisinin incelenmesidir. Çalışmada öncelikle sağlık okuryazarlığı kavramı ve sağlık okuryazarlığı ile ilişkili kavramlar hakkında geniş literatür çalışmasına yer verilmiştir. Çalışmanın metodoloji kısmında Avrupa Sağlık Okuryazarlık ölçeği ile kolayda örneklem yöntemi ile belirlenmiş İstanbul’datoplam beş ilçede ikamet eden 250 ev hanımı kadın ile yüz yüze anket yapılmıştır. Geçersiz sayılan iki anket sonrasında 248 anket üzerinden SPSS programı ile veriler analiz edilmiştir. Araştırmaya katılan ev hanımlarının cinsiyet, meslek, evde herhangi bir iş yaparak para kazanıp kazanmadığı, yaşanılan il, çalışmama nedeni vb. demografik soruları sorulmamıştır. Böylelikle araştırmaya katılanların yaş aralığı ve eğitim durumları ile sağlık hizmetlerinden ne kadar etkin faydalandığı, sunulan hizmetlerin farkındalığı, akıllı ilaç kullanımı hakkındaki bilgileri ve sağlık okur yazarlığı hakkındaki bilgi ve farkındalıkları ölçülmüştür. Yapılan ölçümlerin değerlendirilmesi sonucunda ev hanımlarının yaşları ile sağlık okuryazarlığı arasında istatistiki açından anlamlı bir ilişki bulunmazken eğitim durumları ve sağlık okuryazarlığı düzeyleri arasında istatistiki açıdan anlamlı bir ilişki olduğu gözlemlenmiştir. Veriler, İstanbul Ayvansaray Üniversitesi Akademik Araştırma ve Yayın Etiği Kurulunda, 27.08.2021 tarihinde yapılan 2021/7 toplantı numaralı etik kurul raporu ile toplanmıştır.

Both today's technological development and easy access to information enable individuals to have knowledge about their diseases and research what is good for them. Health literacy has an essential issue in individuals' access to health services. In the broadest sense, health literacy is the ability of individuals to acquire, understand, and use the information to maintain and improve their health for their full well-being. This ability, closely related to all people, affects women even more because a woman's health affects both herself and her family. Many factors affect health literacy, and demographic characteristics are at the forefront of these factors. In the light of this information, the study aims to examine the effect of women's education level on health literacy. In the study, first of all, studies in the literature about the concept of health literacy and the concepts related to health literacy are included. In the methodology part of the study, a face-to-face survey was conducted with 250 housewives residing in five different districts of Istanbul by using the European Health Literacy scale with the convenience sampling method. Two invalid questionnaires were removed from the collected data, and the data were analyzed with the SPSS program over 248 questionnaires. In the study, participants' age range, educational status, how effectively they benefit from health services, their awareness of the services provided, their knowledge about smart drug use, and their knowledge and awareness of health literacy were measured. In the study, the participants were not asked questions such as their profession, whether they earn money by doing any work at home, and the reasons for not working. As a result of the analysis, there was no statistically significant relationship between the age of housewives and health literacy, but a statistically significant relationship was observed between education status and health literacy levels. The data were collected with the ethics committee report with meeting number 2021/7 held on 27.08.2021 at the Academic Research and Publication Ethics Committee of Istanbul Ayvansaray University. An informed consent form was presented to the participants Daha fazlası Daha az

In today's global competitive environment, where the functional benefits of products and services converge, the concept of experience has become increasingly important for brands in creating customer loyalty. In the present study, the effects of sensory, affective, behavioral and intellectual dimensions of brand experience on brand resonance, which represents a high level of active loyalty and interaction in the brandcustomer relationship, were examined through two brands selected from two different sectors. The research was carried out using the survey method by reaching a total of 465 people who are users of the relevant brands. I . . .n the analysis of the collected data, it was aimed to determine the effect of different dimensions of brand experience on brand resonance separately, and to compare the results by repeating the analysis for both brands. The results obtained in the study show that affective, behavioral and intellectual experiences had a significant effect on brand resonance in both selected brands, while sensory experience dimension did not make a statistically significant contribution to explaining brand resonance Daha fazlası Daha az

In this study, it was aimed to determine how consumers who receive distance education services evaluate this education and to determine the factors and expectations that enable individuals to turn to distance education. In this context, by determining the effects of distance education quality, perceived benefit, perceived convenience and advantage on consumer satisfaction, it is aimed to contribute to the marketing strategies that institutions will develop for distance education service. In the research, data from 403 users of an institution providing distance education in English were collected using a survey method; The data obtai . . .ned was tested using the SPSS 20 package program. Research findings show that the quality characteristics (content quality, teacher quality, accessibility, and usability) of distance education positively affect the perceived benefit, perceived convenience and advantage. The perceived benefit from distance education and the perceived convenience and advantage also affect customer satisfaction positively. Accordingly, distance education service enterprises, which can improve the content quality, the quality of teachers and provide easy accessibility, also ensure the satisfaction of the buyers. In addition, it was concluded that the effects of the relevant variables on the satisfaction of users who receive distance education services differ on the basis of the demographic characteristics of the user Daha fazlası Daha az

In the current account, we present an analysis of a non-discriminating criterion under simple additive weighting synthesis, considering a deep decision hierarchy. A non-discriminating criterion describes a criterion where all decision alternatives under consideration perform equally. We question eliminating such a criterion from the decision hierarchy in search of simpler problem representation and computational efficiency. Yet, we prove such an approach may result in order misrepresentations between decision alternatives. This analysis is performed in the form of four research questions that relate to the detection of certain condi . . .tions under which such distortions in the order integrity of decision alternatives will occur, calculating the change in their final performances, distinguishing the alternatives whose performances are consistent, and examining the role of the normalization procedure adopted in averting such distortions when the non-discriminating criterion is ignored. Along these lines, this study provides clear inferences which are of interest to researchers and decision makers, using simple additive weighting and similar methods that rely on additive synthesis Daha fazlası Daha az
