Wijsman rough I-convergence limit point of triple sequences defined by a metric function
Ayhan Esi,Nagarajan Subramanian,AYTEN ESI 원광대학교 기초자연과학연구소 2018 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.15 No.1
We introduce and study some basic properties of Wijsman rough $I-$ convergent of triple sequence and also study the set of all rough $I-$ limits of a triple sequence.
Chlodowsky type (λ, q)-Bernstein Stancu operator of rough triple sequence space of fuzzy numbers
Ayhan Esi,Nagarajan Subramanian,M. Kemal Ozdemir 원광대학교 기초자연과학연구소 2022 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.24 No.1
We define the concept of rough limit set of a triple sequence space of Chlodowsky type (λ, q)-Bernstein Stancu polynomials of fuzzy numbers and obtain the relation between the set of rough limit and the extreme limit points of a triple sequence space of Chlodowsky type (λ, q)-Bernstein Stancu polynomials of fuzzy numbers. Finally, we investigate some properties of the rough limit set of Bernstein Stancu polynomials.

Broken rotor bars in induction motors can be detected by monitoring any abnormality of the spectrum amplitudes at certain frequencies in the motor current spectrum. Broken rotor bar fault detection schemes should rely on multiple signatures in order to overcome or reduce the effect of any misinterpretation of the signatures that are obscured by factors such as measurement noises and different load conditions. Multiple Discriminant Analysis (MDA) and Artificial Neural Networks (ANN) provide appropriate environments to develop such fault detection schemes because of their multi-input processing capabilities. This paper describes two fault detection schemes for broken rotor bar fault detection with multiple signature processing, and demonstrates that multiple signature processing is more efficient than single signature processing.
An Exploration of Korean Discourses on Public Diplomacy
Ayhan, Kadir Jun World Association for Triple Helix and Future Stra 2020 Journal of Contemporary Eastern Asia Vol.19 No.1
There is great confusion over what constitutes public diplomacy (PD), who its actors are, and the relevance of non-state actors. In the Korean context, in addition to the general fuzziness of the concept, linguistic peculiarities of the terms gonggong and gongjung both of which refer to public, waegyo, which is interchangeably used for international affairs, foreign policy and diplomacy, and juche which is simultaneously used for actor and agent, add more layers of confusion. While the term PD in Korea is based almost entirely on Western conceptualization, these linguistic peculiarities prevent fruitful conversations among scholars and practitioners on PD. Against this background, this research note explores and addresses conceptual ambiguities that pertains to PD and the policy discourse on the topic, particularly on non-state PD in Korea. The paper draws on Korean government's PD-related policy documents and Diplomatic White Papers and all relevant academic articles found in Korean-language journals registered in the Korean Citation Index (KCI), which are analysed to gain an understanding of the PD-related policy discourse in Korea.

Objective: The aim of the study was to investigate whether lithium chloride and medroxyprogesterone acetate can potentiate the cytotoxicity of imatinib mesylate in human endometrial cancer in vitro and the effect of midkine in these therapies. Methods: Imatinib mesylate (50 μM), lithium chloride (100 μM), medroxyprogesterone acetate (200 μM) and their combination were applied to monolayer and three dimensional cultures of human Ishikawa endometrial cancer for 72 hours. The cell proliferation index, apoptotic index, caspase-3 and midkine levels, cell cycle distributions in monolayer cultures and cell ultrastructure in spheroid cultures were evaluated. Results were statistically analyzed using the Student’s t-test. Results: All drug applications inhibited cell proliferation (p<0.05), however the combination were the effective groups for 72 hours (p<0.05). Interestingly, although the loss of efficiency was seen higly seen every 24 hours at single applications, the inhibition rates of the combination groups were almost same for 72 hours. In concordance with these results, the apoptotic index, caspase-3 levels (p<0.05), cell morphology and ultrastructure damages were much higher in the combination groups. Imatinib mesylate induced S-phase arrest, however other groups induced G0+G1-phase arrest at 24 hours and all groups induced G0+G1 arrest at 72 hours (p<0.05). Imatinib mesylate and imatinib mesylate with medroxyprogesterone acetate induced highest decrease in midkine levels, respectively (p<0.05). Conclusion: The present study showed that the combination of imatinib mesylate with lithium chloride and medroxyprogesterone acetate is highly active in Ishikawa endometrial carcinoma in vitro and the inhibition of midkine involved in their mechanism of action against endometrium defense.

Throughout the six decades evolution of the public diplomacy concept, international relations approaches have remained at the margins of the field. An important international relations theory that has been virtually non-existent in the public diplomacy literature is the English School of international relations. This theory has been the centerpiece of literature in diplomatic studies, but curiously, has not been applied to public diplomacy. In this editorial, I outline a public diplomacy framework for global governance issues that builds on the English School and Pamment's framework on the intersection of international development and public diplomacy.
