Conference Object Analysis, Design, Test, and Devops in Microservice-Based Software Architectures: Results From Pakistan(Springer international Publishing Ag, 2024) Unlu, Huseyin; Soylu, Gorkem Kilinc; Ahmad, Isra Shafique; Demirors, OnurIn today's software industry, Microservice-based Software Architecture (MSSA) has been a common practice and has been adopted by many companies. MSSA differs from traditional object-oriented architecture in several ways. The architecture moved away from being data-driven and evolved into a behavior-oriented structure. The usage of a single database is replaced by the structures in which each microservice is developed independently and has its own database. Therefore, adaptation demands software organizations to transform their culture. However, there is no de facto method for analyzing, designing, and testing systems for these architectures, similar to object-oriented analysis and design practices. This study aimed to understand how Pakistani software organizations undertake analysis, design, test, and DevOps processes in software projects adopting the MSSA paradigm. To achieve this goal, we surveyed 49 participants from various agile organizations in Pakistan, encompassing different roles and domains. The results reveal that Pakistani software organizations continue using familiar object-oriented analysis and design approaches. However, they have already started exploring event-oriented analysis and design methods for MSSA projects.Article A Cluster of Surprise Egg Toys as Designed Objects at the Intersection of Design and Culture [2](Common Ground Research Networks, 2022) Talu, N.This study examines the cultural context of a cluster of surprise egg toys. The cluster contains 167 toys, collected between the years 1993 and 2015. The study methodology consisted of content analysis involving both qualitative interpretation and quantitative techniques. The interpretation is initiated with the toys’ physical materiality. Analysis is then developed on the compositional modalities of each toy, the place of each in the cluster, and the cluster as a whole. Qualitative interpretation and theoretical analysis of detailed descriptions and groupings of the cluster highlight the central themes found at the intersection of design and culture. Analysis of the cluster reveals that it carries the duality, or the tension, between modern and postmodern cultures with one elevating functionality and the other using storytelling as a means of creativity. They are designed objects and design things blending the two cultures in their physical content, and can be seen as artifacts that contribute to the value of design in everyday life within the context of mass culture. © Common Ground Research Networks, Nilüfer Talu, All Rights Reserved.Article Citation - WoS: 9Citation - Scopus: 13Microservice-Based Projects in Agile World: a Structured Interview(Elsevier, 2024) Unlu, Huseyin; Kennouche, Dhia Eddine; Soylu, Gorkem Kiling; Demirors, OnurContext: During the last decade, Microservice-based software architecture (MSSA) has been a preferred design paradigm for a growing number of companies. MSSA, specifically in the form of reactive systems, has substantial differences from the more conventional design paradigms, such as object-oriented analysis and design. Therefore, adaptation demands software organizations to transform their culture. However, there is a lack of research studies that explore common practices utilized by software companies that implement MSSAs.Objective: In this study, our goal is to get an insight into how practices such as an agile methodology, software analysis, design, test, size measurement, and effort estimation are performed in software projects which embrace the Microservice-based software architecture paradigm. Together with the identification of practices utilized for the MSSA paradigm, we aim to determine the challenges organizations face to adopt microservice-based software architectures.Method: We performed a structured interview with participants coming from 20 different organizations over different roles, domains, and countries to collect information on their views, experience, and the challenges faced.Results: Our results reveal that organizations find agile development compatible with microservices. In general, they continue to use traditional object-oriented modeling notations for analysis and design in an abstract way. They continue to use the same subjective size measurement and effort estimation approaches that they were using previously in traditional architectures. However, they face unique challenges in developing microservices.Conclusion: Although organizations face challenges, practitioners continue to use familiar techniques that they have been using for traditional architectures. The results provide a snapshot of the software industry that utilizes microservices.Article Citation - WoS: 3Citation - Scopus: 3Synthesis, Cytotoxicity, and Antibacterial Studies of 2,4,5,6-Substituted Hexahydro-1h(Wiley, 2023) Yetişkin, Egehan; Gündoğdu, Özlem; Mete, Derya; Celebioglu, Neslihan; Kara, Yunus; Şanlı-Mohamed, GulsahIn this study, synthesis of novel isoindole-1,3-dione analogues bearig halo, hydroxy, and acetoxy groups at the position 4,5,6 of the bicyclic imide ring was performed to examine their potential anticancer effects against some cell lines. A multistep chemical pathway was used to synthesize the derivatives. The cytotoxic effect of trisubstituted isoindole derivatives were evaluated by determining cellular viability using the MTT assay against A549, PC-3, HeLa, Caco-2, and MCF-7 cell lines. The C-2 selective ring-opening products were obtained from the ring-opening reaction of 5-alkyl/aryl-2-hydroxyhexahydro-4H-oxireno[2,3-e]isoindole-4,6(5H)-diones with nucleophiles such as chloride (Cl-) and bromide (Br-) ions. In addition, the ring-opening products halodiols were converted to their related acetates. The anticancer activity of synthesized isoindole-1,3-dione derivatives was investigated against HeLa, A549, MCF-7, PC3, and Caco-2 cells in vitro and resulted in varies cytotoxic effect depend on the group attached to the isoindole molecule. Furthermore, the evaluation of the antimicrobial action of trisubstituted isoindole derivatives against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria was assessed and found out selective inhibition of the both bacterial growth via different trisubstituted isoindole derivatives. The results of this work encourage further research on the potential utilization of trisubstituted isoindole derivatives as cytotoxic and antimicrobial agents.Article A Cluster of Surprise Egg Toys as Designed Objects at the Intersection of Design and Culture(Common Ground Research Networks, 2022) Talu, NilüferThis study examines the cultural context of a cluster of surprise egg toys.
