The scientific publishing industry is dominated by a few publishers that use centralized systems, which decrease the quality of studies and make the publication process longer. Traditional publication systems generally have high publication costs, slow and biased review processes, copyrights held by publishers, lack of rewards for contributors, lack of connection among researchers, etc. Accordingly, we propose a decentralized blockchain-based scientific publication platform to eliminate the traditional publication system deficiencies. The proposed system uses Ethereum smart contracts to accelerate the publication process and abate the biased evaluation process while reducing the publication cost. The proposed model also improves the quality of scientific studies by adding new features to the publication process. The proposed system increases the number of publishers, makes the publication process fully traceable, and makes scientific papers globally available to anyone with a small fee. In addition, the system provides journals with decentralized models and integrates scientific papers with related data or datasets. The editors, reviewers, and cited authors are also rewarded. The proposed system has been implemented using Ethereum Virtual Machine (EVM), which consists of a front-end, middleware, and back-end. When an author submits a manuscript for evaluation, the system automatically finds the most appropriate editors and reviewers for related fields. After the publication process finishes, editors, reviewers, cited authors, and other contributors are rewarded as a system token-based cryptocurrency.

Decentralized finance, powered by blockchain technology, is growing day by day. This field, which emerged a few years ago, today manages $70 billion in assets. In this study, the concept of decentralized finance is discussed and explained the differences from traditional finance. Then, compliance with the legal regulations and the requirements to ensure compliance are mentioned. An evaluation has been made about the financial services offered by the decentralized finance field and the stock market and stablecoins that it uses as a tool while providing these services. Its economic effects, security and, privacy dimensions are examined. In the study, the differences between centralized and decentralized finance, which generally covers legal, economic, security, privacy, and market manipulation, are systematically analyzed. A structured methodology is presented to distinguish between centralized and decentralized financial services

Thermal stress, driven by the combined influence of high temperature and humidity, has become a critical public health concern in rapidly urbanizing Mediterranean cities. This study introduces the QGIS Summer Simmer Index (QSSI) Calculator, an open source plugin developed in Python and Qt Designer to provide fast and reproducible mapping of summer thermal stress. The tool integrates the Summer Simmer Index (SSI) directly into the QGIS environment, enabling users to generate spatially explicit bioclimatic stress maps without relying on external modeling platforms. Adana was selected as the pilot area due to its prolonged hot and humid summer conditions. The results indicate that more than 80% of the urban population is exposed to Hot or Very Hot SSI classes during the summer season, highlighting significant risks for nearly 1.8 million residents. These findings demonstrate the plugin’s value as a practical spatial decision support tool for climate adaptation and urban heat management. Future versions will incorporate additional environmental variables to improve model detail and broaden applicability.

Blockchain technology is one of the technologies emphasized both academically and practically due to the possibility of application integration in different fields. The tourism sector has an interest in blockchain technology due to its early and rapid adoption of technology. Today, blockchain technology is mainly used in finance. However, it is also preferred in tourism due to the opportunities it provides in data management, payment systems, identity management and loyalty programs. In this study, a literature review was first conducted to examine the use of blockchain technology in the tourism sector. Then, the first pioneer companies that emerged in the field of tourism were classified. The relationship between blockchain and tourism is evaluated within the scope of institutional analysis. Then, an analysis was carried out within the framework of the diffusion of innovation theory. As a result, it has been determined that blockchain technology is still developing. However, the promising and growing number of the first sectoral solutions increases the likelihood of acceptance. There is a lack of knowledge about blockchain among industry players and consumers. Integration of blockchain technology with tourism applications is ongoing, but no generally accepted standard has emerged. It has been determined that there are deficiencies regarding local and global legal regulations.

This study investigates the sociocultural and functional organization of residential interiors in Istanbul through an object-based spatial analysis. Utilizing a dataset of over 46,780 photographs from 1,968 Airbnb listings in Istanbul, the research employs computational methods, specifically web scraping with Python for data acquisition, and advanced computer vision and artificial intelligence models (MiniCPM-V:8B and LLaVA-Llama3:8B) for identifying objects and mapping their spatial relationships. The study aims to reveal how the interconnections between objects within distinct room types–dining room, kitchen, living room, bathroom, and bedroom–shape spatial integration and influence daily life activities. Key findings demonstrate the central role of the dining table in dining rooms through strong connections with chairs, the critical function of the sink in kitchens linked to preparation areas and appliances, the dominant relationship between the coffee table and sofa in living rooms reflecting comfort and social interaction, and the distinct functional priorities of hygiene in bathrooms and comfort in bedrooms. The analysis reveals that the spatial structure of domestic environments in Istanbul is increasingly characterized by object clusters and user-object interactions, moving beyond traditional physical boundaries. These findings underscore the significant influence of cultural values, hospitality practices, and social interaction patterns on the spatial configuration and integration of contemporary homes, offering insights into the evolving nature of domestic space in an urban context.
