Authors: Dinçer Gülşah , Yıldız Emel
Published: December 2024

Çağdaş Pazarlamada markalaşma; tüketici memnuniyetinin sağlandığı, tüketiciye vaat edilen hizmetin sunulduğu ve tüketici ile markanın birbirini doğru anlamasını sağlayan bir süreçtir. Tüketicilerin ürünü satın almaktaki amaçlarından biri ürünü denemek ve oluşturacağı bağlılığı değerlendirmektir. Tüketici ile ürün arasındaki ilişkinin kalitesi ve sürekliliği işletme başarısını önemli ölçüde etkilemektedir. Bu anlamda işletmelerin, tüketicilerin satın alma ve satın aldıkları ürünü değerlendirmelerine kadar geçen süreyi doğru yönetmeleri gerekir. Tüketici hafızasında ürün hakkındaki düşüncelerin kalıcı olmasında marka rezonansının önemli bir yeri vardır. Marka rezonansı, markaya bağlılık ve bu bağlılığın derecesi olarak ifade edilebilir. Literatür incelemesinde marka rezonansını etkileyen çeşitli kavramlar üzerinde durulmuş olsa da marka rezonansını etkileyen keşfedilmemiş alanların yer aldığı fark edilmiştir. Bu düşünceden yola çıkılarak, literatüre katkıda bulunmak ve markalaşmada marka rezonansının etkileyen faktörleri belirlemek amacı ile marka deneyimi, marka tutumu ve ilişki kalitesinin marka rezonansına etkileri incelenmiştir. Araştırma için beyaz eşya kullanan 401 kişi örneklem olarak seçilmiştir. Araştırmada veri toplama yöntemlerinden kolayda örnekleme yöntemi kullanılmış olup, veriler açık ve kapalı uçlu soruların yer aldığı anket ile çevrimiçi olarak uygulanmıştır. Elde edilen veriler AMOS 24 ve SPSS 21 istatistik paket programları ile test edilmiştir. Araştırma sonucunda ilişki kalitesi ve marka deneyiminin marka rezonansını pozitif yönde etkilediği ayrıca marka tutumunun bu etkide aracı rolü olduğu tespit edilmiştir.

Authors: Polat Erhan , Altun İslam , Dabakoğlu Mehmet
Published: December 2024

Günümüz dünyasında, ticaret üzerinde etkili olan temel faktörler arasında politik riskler giderek daha önemli hale gelmektedir. Ülkeler arasındaki güç mücadelesi, toplumsal olaylar, uluslararası sözleşmeler ve yoğun rekabet ortamı, ticari faaliyetlerde politik risklere yönelik etkili tepkilerin geliştirilmesini zorunlu kılmaktadır. Genel olarak, risklerle başa çıkma metotları geliştirilmiş olup, bu metotlar politik riskler için de uygulanmaktadır. Risk yönetim stratejileri ve risklerin olumsuz sonuçlarını azaltmaya yönelik kontrol faaliyetleri bu bağlamda önem kazanmaktadır. Kontrol faaliyetleri, iç kontrol sistemine destek veren ve risk değerlendirmesi sonucunda ortaya çıkan risklere karşılık verilmek üzere oluşturulan tespit edici, önleyici, düzeltici faaliyetleri kapsamaktadır. Bu çalışmada, Güneydoğu Anadolu İhracatçı Birlikleri (GAİB) üyesi firmaların politik risklerinin tespiti, risk yönetim stratejileri ve kontrol faaliyetleri arasındaki ilişki incelenmiştir. Araştırmaya, bölgedeki 274 farklı sektörde faaliyet gösteren işletme katılım sağlamıştır. Anket yoluyla elde edilen veriler SPSS paket program yoluyla analiz edilmiştir. Analiz sonuçlarına göre politik riskler ile risk yönetim stratejileri ve kontrol faaliyetleri arasında anlamlı bir ilişki bulunmadığı tespit edilmiştir. Bu durum firmaların risk yönetim stratejilerini belirlerken politik riskleri yeterince dikkate almadıklarını göstermektedir. Çalışma, risk yönetimi stratejilerini güçlendirmek için kontrol faaliyetlerinin artırılması, büyük ölçekli işletmelerin deneyimlerinden yararlanılması ve uygulamaların iyileştirilmesinin önemini vurgulamaktadır. Politik risk ortamı ve risk yönetim stratejileri arasındaki ilişkinin daha derinlemesine incelenmesi için daha kapsamlı araştırmalar önerilmektedir.
EKONOMİK BÜYÜME, CARİ AÇIK VE BÜTÇE AÇIĞI ARASINDAKİ İLİŞKİLER: TÜRKİYE ÖRNEĞİNDE JOHANSEN EŞBÜTÜNLEŞME ANALİZİ
Authors: Yıldırım Nuh Ekrem
Published: December 2024

Bir ülkenin önemli ekonomik performans göstergelerinden birisi olan cari işlemler hesabı, ekonomik ve siyasi çevreler tarafından takip edilmektedir. 1980’ler sonrasında sermaye hareketlerinin yaygınlaşmasıyla cari açık kavramı, ülkelerde temel problemler arasında yer almıştır. Ülkelerin belirli bir dönemdeki diğer ülkelerle olan mali ve ekonomik ilişkileri dış ödemeler bilançosu ismi verilen bir tabloda izlenir ve cari işlemler dengesi de bu tablonun alt kalemini oluşturmaktadır. Cari işlemler açığı, bir ülkenin dış dünya ile olan ekonomik ilişkilerini ortaya koymakta ve bu cari açığın azaltılması için ülkelere önemli görevler düşmektedir. Cari açığın uzun dönemde borçlarla kapatılma gayreti ülkelerin gelecek nesillerinin ekonomik refahına ciddi zararlar vermektedir. Bir ülkenin ekonomik olarak büyümesi için, cari açığın sürdürülebilir seviyede olması önemlidir. Son yıllarda cari açık ile ilgili birçok çalışma yapılmış ve Türkiye’de en çok tartışılan konular arasında yer almıştır. Bu çalışmanın amacı, 2002-2021 zaman aralığında Türkiye’nin ekonomik büyüme, cari açık ve bütçe açığı yıllık verileri arasındaki uzun vadeli ilişkileri eşbütünleşme metodolojisi ile incelemektir. Johansen eşbütünleşme analizi bulgularına göre cari işlemler açığındaki %1’lik bir artış, GSYH’yi yaklaşık olarak %0.59 azaltmakta; bütçe açığındaki %1’lik bir artış ise GSYH’yi yaklaşık olarak %1.68 oranında artırmaktadır. Hata düzeltme katsayısı ise dengeye uyarlanma sürecinin hızlı bir şekilde gerçekleştiğini, ayrıca denge ilişkisinden sapmaların bir dönemden daha kısa bir dönemde tekrar durağan bir sürece yaklaştığını göstermektedir.

Olumsuz tutum ve inanç konusunda daha derinlemesine araştırmalar yapılması önerilmektedir.
Magnetic Resonance Imaging Prior Authorizations for Orthopaedic Care Are Negatively Affected by Medicaid Insurance Status
Authors: Harrer Samantha , Hedden Kathryn , Mikaeili Sadegh , Bazrafshan Nazila , Gentile Pietro M. , Gealt David B. , Brown Matthew L.
Published: December 2024

Background:

Magnetic resonance imaging (MRI) has revolutionized musculoskeletal care. However, its high costs and high utilization has prompted many insurance payors to require a prior authorization. This process remains burdensome and results in delays to patient care. The purpose of this study was to examine the relationship between several variables and the denial rate of outpatient MRI prior authorization requests from a single institution's department of orthopaedics.

Methods:

MRI prior authorization insurance data was retrospectively collected from January 2019 to December 2022. Patient demographics, imaging characteristics, and insurance details were extracted and stratified into generalized categories. Analysis of variance, multivariate logistic regression models, and odds ratios (ORs) were used to predict the likelihood of request denial with α = 0.05.

Results:

Of the 17,913 total MRI prior authorization requests identified, 885 (4.94%) were denied. Race and socioeconomic status were not markedly different between the authorized and denied cohorts; however, primary insurance payor, chief symptom, and anatomic location to be imaged were found to have notable differences between authorized and denied cohorts (P < 0.0001). MRIs of the spine were less likely to be authorized compared with the shoulder (OR 0.51), upper extremity (OR 0.43), knee (OR 0.38), lower extremity (OR 0.34), and foot and ankle (OR 0.75) with P < 0.02 for each. Horizon NJ Health and Horizon Blue Cross Blue Shield, both Medicaid payors, were also less likely to authorize requests compared with other payors (Aetna, OR 0.37 and United Healthcare, OR 0.36) (P < 0.01 for both).

Conclusion:

The low denial rate of initial prior authorization requests over 4 years at our institution underscores the questionable utility of the prior authorization process. Our results are consistent with the current literature that has reported higher rates of denials for MRI prior authorization requests of the spine. Although we were not able to quantify the effect of these denials on patient care, the overall time required to process these requests undoubtedly causes delays in patient care. despite no notable difference seen in socioeconomic status, Horizon NJ Health, a major provider of only Medicaid insurance plans at our institution, was associated with a higher likelihood of denial. This suggests that MRI prior authorization requests submitted for Medicaid patients are more likely to be denied and cause an inequitable delay in care due to this process.

An Analysis on Strategies for English Translation of Chinese Cuisine Names from the Perspective of Skopos Theory: A Case Study of A Bite of China
Authors: Xu Qian
Published: December 2024

The core of Skopos theory is that in the process of translation, translators can realize dynamic communication between two languages with different cultural backgrounds according to the purpose of the original text and their own subjective initiative. Skopos theory places the translator in a broader social context, and translators should consider all possible participants when carrying out translation activities. Taking the English version of A Bite of China as an example, this paper summarizes the problems in the translation process by arranging and classifying the names of Chinese dishes in the program and their English translations. The cultural information conveyed, and the main methods of translation are proposed, including literal translation, transliteration, literal translation plus transliteration, free translation, literal translation plus free translation, etc. After in-depth comprehensive analysis, it is believed that enough attention should be paid to the English translation of Chinese dish names, and translators should improve their cultural awareness in the process of translation, so as to better spread Chinese culture.

Developing power control algorithms for dynamic multi-connection industrial wireless sensor networks
Authors: Do Thanh Quan  , Bùi Tiến Anh
Published: December 2024

In this paper, we propose a Dynamic Multi-Connection Industrial Wireless Sensor Network (DMC IWSN) model to improve data transmission efficiency in a factory workshop. We introduce a new power control algorithm called Window-Selection (WS), which adjusts sensor power based on predefined upper and lower limits. The algorithm reduces power when it exceeds the upper limit, increases power when it falls below the lower limit, and maintains power within these bounds. We compare the performance of the WS algorithm with the Max-Min (MM) algorithm, and a scenario no power control in terms of the weakest sensor capacity and total capacity in uplink transmission. Simulation results show that the WS algorithm achieves the highest capacities, while the MM algorithm moderately improves system performance in the DMC IWSN model.
Research on simulation of a bullet skimming the ground by the finite element method
Authors: Phan Ba Binh , Phan Van Vu
Published: December 2024

It is greatly complicated to research the process of bullets penetrating into the ground due to the diversity and heterogeneity of ground physical characteristics. The empirical formulas have been developed for scenarios involving deep penetration of bullets into the ground so far; however, equivalent calculations for bullets skimming the ground scenarios remain absent. This paper has established a finite element method (FEM) simulation model for deep penetration and validated it against empirical data. Leveraging this validated model, simulations have been extended to examine the bullets skimming the ground behavior of bullets. The results have delineated the impact angles at which bullets skimming the ground occur for soil with average compaction density. This methodology can be adapted to various soil types to construct a comprehensive set of parameters for bullets skimming the ground angles, thereby optimizing artillery performance.

Published: December 2024

This paper introduces a design for a microwave substrate integrated waveguide (SIW) power amplifier (PA) for modern wireless communications. The amplifier design incorporates complementary split ring resonator (CSRR) structures integrated within the SIW to achieve low-loss characteristics and miniaturization through a below cut-off frequency operation approach. The designed PA operates at 8 GHz and exhibits good performance, which are measured output power Pout of 35.51 dBm, a maximum power added efficiency PAE of 47.2% and a power gain of 12.51 dB. The final circuit occupies just a compact size of 41 x 15.7 mm2 benefiting from using the CSRR structure. The proposed PA employs a low-cost QFN packaged GaN HEMT device from Qorvo and it was designed and fabricated on a cost-effective RO4003C substrate. The simulated results agree well with the measured ones validating the accuracy of the design. With promising measured results, the proposed PA can be a potential candidate for using in the modern wireless communication systems.

Authors:   MEng Electrical Engineering, CEAS, University of Cincinnati, Das Priyanka
Published: December 2024

Accurate localization underscores effective operations for underwater Remotely Operated Vehicles
(ROVs). Localization in underwater ROVs faces challenges due to signal attenuation, sensor drift, and
environmental noise, but it suits most engineering experiences. Exploring optimization techniques for sensor
integration to enhance localization accuracy leverage advanced algorithms and sensor fusion methods.
Diversified sensors like Doppler Velocity Loggers (DVL), Inertial Measurement Units (IMU), and acoustic
systems rely on Kalman filters, particle filters, and machine-learning approaches for best localization. Bridging
the gap associated with sensors and improving data fusion foster ROV reliable navigation. The driven
environmental trials for introduced sensors showcase a dynamic aspect of engineering exploration into
localization technology. Efficient sensor fusion and integration through diversification of ROV technologies
guarantee precise localization for different underwater explorations, including mapping, inspections, and
construction. Therefore, companies and experts focusing on deep-sea and underwater surveys utilize optimized
sensor integrations, better outcomes, and reduced operations risks in localization to support complex exploration
missions.

Authors:   Assistant Professor in Computer Science, Khalsa College (ASR) Of Technology & Business Studies,  Mohali –Punjab., Kaur Simranjit
Published: December 2024

Cyber-physical systems are an essential and frequently used infrastructure for resolving today's most
challenging problems. As we all know, making rapid and accurate decisions in a big data setting (also called a
critical/significant environment) is a tough challenge. This chapter's potential investigates the specifics of one of the
most significant technological revolutions developing "Cyber-Physical Systems" and the increasing role of artificial
intelligence techniques in these systems. Artificial intelligence techniques are essential in information security
because they can rapidly evaluate millions of incidents and recognize various threats – from malware leveraging
zero-day vulnerabilities to risky actions that might result in a phishing attack or download of malicious code. We
conducted an efficient search in Web of Science, PubMed, Scopus, and EBSCO for articles published up to April
2021 that addressed federated learning, deep learning, machine learning, graph-based approaches, intrusion detection
tree approaches, and Signature Based Malicious Behavior Detection in cyber-security. Additionally, the work
compared various attack detection techniques in cyber-physical systems against associated challenges and quality
metrics such as accuracy, bandwidth, Variance of Noise, Sparsity rate, Pushing recall, F1-score, precision, and recall.
It extensively discusses the context for artificial intelligence in cyber-security, including the different cyber-physical
security attacks. The unique aspect of this work is that the survey summarizes current concepts and their limitations,
focusing on future research potential in artificial intelligence techniques for Cyber-Physical Systems. This research
work would facilitate multiple researchers and scholars investigating cyber-physical domains and serve as a basis for
further studies.

A New Crowdfunding Model for Financial Inclusion Based on Donations and Interest-Free Debt: A Fuzzy Agent-Based Simulation Approach
Authors: Lamrani Alaoui Youssef , Elfakir Adil , Tkiouat Mohamed
Published: December 2024

Purpose — Although microfinance was initially heralded as a promising methodology for reducing poverty, it has become increasingly criticised. Hence, calls for innovative models that promote financial inclusion have intensified. This research aims to fill in this gap by developing a new model that combines donation-based crowdfunding with interest-free lending, and subsequently evaluating its performance using appropriate decision-making tools.
Design/Methodology/Approach — The study adopts an agent-based perspective whereby the idea is to encode the behaviour and decisions of the model’s entities in straightforward rules and subsequently analyse the outcomes of their interactions through agent-based simulation (ABS). To address the uncertainty inherent in human agents’ judgements, a fuzzy logic inference system has been incorporated as well.
Findings — Findings show that the proposed model has (i) a better success rate in funding new entrepreneurs, (ii) higher collection of management fees, and    (iii) a reduced number of failed projects. This model incorporates monitoring to reduce moral hazard risks and provides health and life insurance for entrepreneurs, ensuring both project efficiency and the well-being of the entrepreneurs.
Originality/Value — This study contributes to the Islamic crowdfunding (ICF) literature by introducing a new hybrid model that integrates donations with interest-free loans. It explores the impact of this design on crowdfunding platform success and the well-being of micro-entrepreneurs, using an agent-based perspective.
Research Limitations/Implications — Despite its merits, the proposed model has certain limitations. Like many crowdfunding models, entrepreneurs who fail to secure financing may be susceptible to the risk of idea theft. Concerning model validation, although a significant portion of the model’s data is calibrated using real data, the conception and simulation introduce certain free parameters (such as the learning factor and monitoring efficiency), which renders the validation process somewhat challenging.
Practical Implications — This innovative solution can help crowdfunding platforms refine their policies and interventions to enhance project funding success and contribute significantly to broader financial inclusion efforts.
Essence from within: Unveiling the voices of Nepalese master's degree students in English and biology education on internal assessments within the semester system
Authors: Shah Rajendra Kumar , Paneru Narendra Raj , Bohora Bhuwan Bahadur
Published: December 2024

This study explores the changes in the examination system at Tribhuvan University, which originally adopted an annual examination system, switched to a semester system in 1971, and then reverted to the annual system in 1981. In 2013, the semester system was reintroduced, and it is now widely implemented across the university and other institutions in Nepal, although some undergraduate programmes still follow the annual system. These changes reflect ongoing efforts to reform the examination system, yet it remains unclear whether these reforms were based on comprehensive research and whether students’ experiences were adequately considered. The major objective of this study is to explore the lived experiences of Master’s degree students regarding internal assessments within the current semester system. A phenomenological approach was employed, with in-depth interviews conducted with eight students from the MEd English and Biology Education programmes at Tribhuvan University, Sanothimi Campus. The findings suggest that while the university has made significant strides in improving its educational and assessment systems, further improvements are necessary in the internal assessment procedures. Key areas for reform include enhancing student attendance, fostering more active classroom participation, involving students in research activities, and improving writing skills. Additionally, the study highlights the need for improvements in the quality of written examinations system and recommends that the curriculum be more aligned with real-world applications and focused on skill development.

Published: December 2024

A green city is a city with good planning that has an environmentally friendly character and seeks to manage its resources for everything that focuses on environmental balance. In an effort to create a green city, various planning and implementation programs have been and are being carried out, both by the government, private sector and also the community in order to realize the concept of a green city. One form of sustainable program to support, this is known as the Green City Development Program (Program Pengembangan Kota Hijau) or more easily abbreviated as P2KH which refers to the Regional Spatial Planning Plan (Rencana Tata Ruang Wilayah) or abbreviated as RTRW. Green cities themselves have indicators called eight (8) green city attributes, including: green open space, green waste, green transportation, green water, green energy, green building, green community, and green planning and design. The background on this research is presented in three criteria, including empirical problems, theoretical frameworks, and legal foundations used as references or legal guidelines for implementing the green city concept. It is known that the complexity of society's demands increases as the population increases. This of course becomes a challenge in managing environmental resources. Problems such as traffic jams, air pollution, increasing volumes of waste, slums, flooding and other social inequality problems, which of course with the increasing population, logically result in the living area becoming increasingly narrow. What happened in Malang City is no exception. Malang City has great potential for better services, especially in the context of realizing a green city. The research results show that there are eight green city attributes that have been implemented in several activities in Malang City. In practice, these eight attributes need continuous development. The concept of a green city is not a simple concept that can be planned once and then realized, it is a holistic, continuous and sustainable concept. Therefore, this research provides an in-depth look at strategies for developing green city attributes in Malang City using a qualitative approach. The strategy for developing green city attributes in the city of Malang is carried out through the SOAR and SWOT analysis stage, the development stage, the role enhancement stage, the support and development stage of appropriate technology, coordination and synergy between actors, as well as evaluation and supervision in improving the quality of the green environment and public awareness of development of the green city concept in Malang City.
