Challenges of using software size in agile software development: A systematic literature review
(CEUR-WS, 2018) Hacaloglu,T.; Demirors,O.; Information Systems Engineering
Software size is a fundamental measure for software management. Size is used for a variety of purposes, such as benchmarking, normalization, and portfolio measurement, and it is frequently considered as the sole input of estimation. Estimations can be produced for various reasons; e.g., to predict effort, cost and duration of software development projects. There are different types of software size measures. Particularly in projects where agile methodologies are adopted, measurement becomes a significant challenge as it is perceived as a non-value-added task and records of tasks such as requirements identification are not always consistent. The difficulties of applying traditional size measurement techniques in agile contexts, however, do not diminish the need, and new methods and techniques are introduced to improve the manageability of the agile projects. In this paper, we discuss estimation and measurement approaches in relation with ―software size in agile contexts. Based on this review, we present the perceptions of software size and related challenges, such as misinterpretation of size, difficulties in implementation, and acceptability of the measurement processes. We anticipate that providing a baseline for the state of software size measures in agile contexts and presenting related challenges, particularly in terms of its acceptability by practitioners can shed light on the development of new techniques. © 2018 CEUR-WS.

Comparative Analysis Of Patch Antennas With Rectangular Slots For Laminate And Wearable Materials At 5g Networks
(Institute of Electrical and Electronics Engineers Inc., 2024) Hakanoglu, B.G.; Agaya, E.; Gulmez, G.; Yalinsu, S.
In this study, new multi-band patch antenna design models are proposed for use in 5G networks. The purpose of the designs is to open rectangular slots on rectangular shaped patch antennas and bring them to the desired operating conditions with parametric analyzes. The designs were carried out by following the same procedure steps using five different dielectric laminate substrate materials, such as RO3003, RT6006, FR4, RO3203, RO6010, and one denim fabric base material. The antennas were compared in terms of return loss, gain and radiation characteristics. Except for the antenna designed with RO3203 at certain values of rectangular slots, radiation at multiple frequencies was obtained at 5G frequencies. With the proposed method, improvement was observed for return loss and bandwidth characteristics in the RO3203 based antenna. This study will be a resource for antenna researchers by revealing the responses of different substrate materials to the same design method for 5G bands in patch antennas. © 2024 IEEE.

A computer-controlled triaxial swelling test apparatus
(2004) Bilir,M.E.; Müftüoǧlu,Y.V.; Sari,D.
To avoid the problems encountered during and after the construction of engineering structures built within swelling rocks or soils, data related to swelling stresses and strains should be used in the design stage. For an effective design, it is important that the data used for this purpose should be derived from triaxial swelling tests. In this article, a re-designed and computer-controlled triaxial swelling test apparatus is introduced. Due to the limited amount of test equipment, the work associated with triaxial swelling tests has been rather limited and consequently a test standard has not been developed yet. The computer-controlled triaxial swelling test apparatus has made tedious swelling tests easier and thus it has provided better possibilities for the investigation of the triaxial swelling behavior of soils and rocks.

The Effect of Gamification on Brand Awareness: a Study of Retail Industry and Healthy-Living Applications
(Henry Stewart Publications, 2024) Alsan, H.; Tengilimoğlu, D.
Rapid developments in digitisation have resulted in gamification (ie, the use of game elements and game mechanics in non-game areas) becoming more common and easy to apply in digital environments. This study examines the use of gamification in the field of marketing, specifically its effects on brand awareness. As the paper shows, gamification helps to establish important bonds between the brand, the company and the customer. In this context, the paper analyses brand awareness by means of the survey method. Due to the size of the study population, the scope of the study was narrowed to apps promoting healthy living and apps produced by the retail sector. Convenience sampling was used to recruit 400 respondents. The survey found that gamification has a positive effect on brand awareness (r = 0.55) and that attitude to gamified apps has a positive effect on brand awareness (r = 0.58). Certain demographic factors were also found to influence the use of gamified apps. © HENRY STEWART PUBLICATIONS 2050-0076 (2024).

Estimation of the Mean Radiant Temperature in Office Buildings Using an Artificial Neural Network Developed in a Phyton Environment
(Taylor & Francis Ltd, 2025) Ozbey, Mehmet Furkan; Lotfi, Bahram; Turhan, Cihan
Thermal comfort describes an occupant's state of mind in a thermal environment, influenced by six parameters: air velocity, relative humidity, air temperature, mean radiant temperature (MRT), clothing value, and metabolic rate. MRT is the most problematic parameter since the obtaining process is difficult and time-consuming. MRT can be acquired by several methods such as calculations, measurements, assumptions, and software programmes. However, the methods have complexities and uncertainties. Comprehensive models are needed to obtain MRT. To this aim, this study presents an alternative method using one of the artificial intelligence methods, Artificial Neural Network (ANN), to predict MRT for indoor environments to abstain from the difficulties and complexities. A case building is selected in a university office building in Ankara, T & uuml;rkiye. The proposed model is developed and coded in a Python programming environment to predict the MRT using ANN. The results indicate that the ANN model, using only four inputs, predicts MRT with an R-2 value of 0.94 compared to the globe thermometer measurement method. The model's advantages over methods include simplicity, time efficiency and learning from the limited datasets such as difficulty in calculating terms like MRT.

Examination Of The Relationship Between Money Laundering And Tax Crimes Based On Financial Action Task Force (fatf) Standards: A Stocktaking For Türkiye
(Sosyoekonomi Society, 2025) Bülbül, D.; Güler, K.
Money laundering and tax crimes are financial crimes that have considerable costs to society, and there are notable interconnections between them. This study aims to examine the contribution of the measures introduced against money laundering by the Financial Action Task Force (FATF) to tax compliance and combating tax crimes and to evaluate the situation in Türkiye. The conceptual framework regarding these crimes and the connections between them are established in this context. The effects of the measures introduced against money laundering on tax compliance and crimes based on FATF standards are investigated. Finally, the situation in Türkiye is examined and analysed. The study shows that customer identification and reporting of suspicious transactions can contribute significantly to identifying taxpayers, transactions, and income that should be taxed and detecting tax evasion. Still, this potential is not sufficiently utilised in our country. © 2025, Sosyoekonomi Society. All rights reserved.

Exploratory Review of Quantum Computing Software Requirements Specification and Their Measurement
(CEUR-WS, 2024) Hacaloglu, T.; Soubra, H.; Bourque, P.
Quantum software sets itself apart from classical software owing to its powerful computational abilities rooted in entanglement and superposition. Unlike classical software, quantum software diverges notably across various dimensions, including computational models, hardware architectures, algorithms, deployment platforms, and problem domains. Quantum software is also often not standalone and interacts heavily with classical software, stressing the importance of carefully considering hybridization. From a software engineering standpoint, researchers generally agree that a different approach is required for quantum software, and they advocate a Quantum Software Development Life Cycle (SDLC). This exploratory study briefly outlines the specifics of quantum software, overviews the proposed approaches regarding the software requirements of quantum software, and then reviews the current alternatives for measuring the functional size of quantum software. This study indicates that only a few papers in the literature discuss the requirements and functional size measurements of quantum software. Their results are also mostly conceptual and have not yet been empirically validated. Functional size measurement using quantum software remains an open area for further research. © 2024 Copyright for this paper by its authors.

Factors Affecting Entrepreneurial Activity in an Emerging Economy in the Case of Turkey: the Role of the Covid-19 Pandemic
(Academic Conferences and Publishing International Limited, 2024) Usul, N.; Karadeniz, E.; Özdemir, Ö.
This paper seeks to study factors influencing the early stages of entrepreneurship within the context of coronavirus pandemic, specifically within an emerging country. We utilize from a unique dataset collected by Global Entrepreneurship Monitor which is the sole global research repository compiling data on entrepreneurial activities and individual entrepreneurial attributes across 50 countries worldwide. In particular, this study focuses on the GEM survey data pertaining to Turkey during the period coinciding with the COVID-19 pandemic in the year 2021. The analysis is done by binary logistic regression with dependent variable being total entrepreneurship activity. Findings indicate that opportunity-driven respondents, with high-status aspirations, possessing necessary skills and acknowledging the challenges of their entrepreneurial environment, are the ones who show a higher probability of engaging in entrepreneurial activities. While these variables have been scrutinized in existing literature, our contribution lies in examining their effects within an emerging market, a relatively understudied context, particularly in the aftermath of a global pandemic. Results suggest that the individuals reporting a substantial increase in income during the pandemic, and perceiving a harder business environment to start a new venture show elevated probabilities of becoming an entrepreneur. These two are the pandemic-related variables demonstrating statistical significance, which highlights the fact that this period created its entrepreneurs, who exploit high resilience and dynamic capacity to adapt to crisis times. They experienced a significant increase in their income, capitalized on their comparative advantage in entrepreneurial skills within an environment where starting a business is not easy and took advantage of the opportunities seeking for high status using their adaptive capacity. These findings are consistent with Theories of Resilience and Dynamic Capabilities. Finally, younger respondents are more inclined to engage in entrepreneurial activity, which is consistent with the existing literature. In light of these findings, policymakers are encouraged to invest in educational programs for potential entrepreneurs to enhance their self-efficacy, given that the necessary skills for business initiation emerge as a pivotal factor for engaging in entrepreneurial activities. Moreover, creating platforms for successful entrepreneurs to share their experiences could amplify the perceived prestige associated with entrepreneurship, which may attract potential entrepreneurs. © 2024 Academic Conferences and Publishing International Limited.

A Feminist Reading of Rupi Kaur's Milk and Honey
(Peter Lang Publishing Group, 2024) Serdaroğlu, D.; Department of English Language and Literature
Considered to be a fourth wave of feminist, Rupi Kaur deals with the problems of women, such as sexual discrimination, misogynism, violence and commodification of the female body. Despite the harsh criticism targeting her minimalist and simple writing style embellished with her own illustrations, Kaur makes her voice heard throughout the world via the Internet- especially the social media- by sharing her poems on the Instagram. The poet divided her milk and honey (2014), into four parts; in each of the four parts which symbolizes a different stage of a woman's life replete with fears, challenges, struggles and hopes, she not only talks about the sufferings of women and female empowerment but also with her illustrations, she attracts many readers visually. Hence, this chapter analyses Rupi Kaur's milk and honey from a feminist perspective by focusing on victimization and commodification of women as well as women empowerment with regard to her non- traditional writing style. © 2023 Peter Lang Group AG, Lausanne.

First Results From the Snd@lhc Experiment
(Sissa Medialab Srl, 2025) Durhan, O.
SND@LHC started taking data at the beginning of Run 3 of the LHC. The experiment is designed to perform measurements with neutrinos produced in proton-proton collisions at the LHC in an energy range between 100 GeV and 1 TeV. It covers a previously unexplored pseudo-rapidity range of 7.2 < η < 8.4. The detector is located 480 m downstream of the ATLAS interaction point in the TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of tungsten plates, interleaved with emulsion and electronic trackers, followed downstream by a calorimeter and a muon system. The configuration allows efficiently distinguishing between all three neutrino flavours, opening a unique opportunity to probe physics of heavy flavour production at the LHC in the region that is not accessible to ATLAS, CMS and LHCb. This region is of particular interest also for future circular colliders and for predictions of very high-energy atmospheric neutrinos. The detector concept is also well suited to searching for Feebly Interacting Particles via signatures of scattering in the detector target. The experiment has published several results. This work focuses on the experience gained from the first measurements and how this is being used to achieve the physics goals of SND@LHC. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

Investigation of Photosensitivity Side Effect of Systemic Doxycycline Used in the Treatment of Acne Vulgaris
(Pakistan Association of Dermatologists, 2023) Hasanbeyzade, S.; Saadet, E.D.
Objective In this study, photosensitivity and other side effects due to the usage of systemic doxycycline in summer during acne treatment and whether these side effects were related to the demographic and clinical properties of the patients were investigated. Methods Before conducting the study, approval of the ethics committee of the hospital was obtained. 251 patients who applied to the dermatology outpatient clinic between 01.05.2021-30.09.2021 and were diagnosed with moderate-severe acne were included in the study. Demographic characteristic of the patients, clinical and treatment features, and development of photosensitivity or other side effects during or after the treatment were examined. Results Side effects were seen in 9 out of a total of 251 patients (3.6%). Among these patients, 5 patients (2%) had erythematous papules or plaque-like lesions on the face, and 4 patients (1.6%) had erythematous papules on the forearms. A statistically significant difference for age, sex, the severity of the disease, and treatment dose was not detected between groups classified according to the side effects (p values were respectively: 0.67, 0.058, 0.343, and 0.858). Statistically, a significant difference was found between these groups for the treatment period and usage of sun protection (p values were respectively: 0.011 and 0.003). Conclusion In patients who have erythematous papules and plaques on the face, these findings regressed with topical treatment. Therefore these findings were considered to be due to the usage of the topical acne agent. However, most patients having erythematous papules on their forearms were not using sunscreens and had personal and/or familial history of atopy. Because side effects did not require cessation of the systemic treatment and regressed with administered treatment; in the case of regular usage of sunscreen and utilization of benzoyl peroxide in combination, the photosensitivity side effect was thought to be minimal. © 2023 Pakistan Association of Dermatologists.
