Antibiotic resistance (AR) has emerged as a critical global public health concern, particularly due to the spread of antibiotic-resistant bacteria (ARB) and their genes in natural environments. The oceans, which host diverse ecosystems and serve as major food sources, are increasingly affected by ARB pollution, originating from human, agricultural, and industrial activities. Simultaneously, climate change (CC) exacerbates the situation by raising ocean temperatures, lowering pH, and altering marine biodiversity—creating optimal conditions for bacterial survival and gene transfer. This review explores the interconnectedness between ocean pollution and CC and how both factors influence the distribution and persistence of ARB and antibiotic resistance genes (ARGs) in marine ecosystems. Through a systematic literature review of 174 peer-reviewed articles, the study highlights how anthropogenic pollutants—especially antibiotics, heavy metals, and plastics—contribute to resistance emergence. Furthermore, it discusses the transmission pathways from pollution hotspots (e.g., hospitals, agriculture, wastewater) to the oceans. The One Health (OH) strategy is presented as a comprehensive solution to address the environmental, human, and animal health risks posed by antibiotic pollution. This paper serves as a basis for future research into surveillance, mitigation, and policy interventions for controlling AR in marine environments.

As business complexity and global competition intensify, the limitations of traditional cost accounting systems in providing relevant information for strategic decision-making become increasingly apparent. This has driven the adoption of Activity-Based Costing (ABC) and subsequently Activity-Based Management (ABM), which have evolved as vital tools to accurately allocate costs based on activities and transform this information into value-enhancing and efficiency-improving strategies. This study aims to map the landscape, influence, and visibility of ABC and ABM publications through a comprehensive bibliometric analysis using VOSviewer. The research method involves a Systematic Literature Review (SLR) for data collection and screening from 488 publications (2023-2025) indexed in Scopus from Google Scholar, followed by data analysis and visualization of co-authorship and keyword co-occurrence networks. The analysis results show the dominance of core concepts such as "activity-based costing/management," "activity," "costing," and "management" as the foundation of research. Identified thematic clusters include the basic applications of ABC and its impact on performance, managerial aspects of ABM, efficiency, and the challenges and benefits of implementation. Temporal trends indicate a shift in the focus of recent research towards the strategic and managerial contributions of ABM/ABC in enhancing efficiency, supporting decision-making, and driving organizational performance. Density visualizations confirm research "hotspots" in these areas, while also highlighting potential research gaps for the future. The conclusion demonstrates the continuous relevance of ABC and ABM as adaptive cost and performance management tools, as well as the evolution of the discipline continually adapting to modern business's strategic needs, guiding researchers and practitioners for further exploration.

Fire is an event that often occurs due to human negligence. Losses from fire include damage to goods, business delays and can even cause loss of life. For early handling of fires, a "Fire Fighting Control Design Using MQ-2 Sensor and Fuzzy Logic Based 5 Channel Flame Sensor" has been created. This tool uses the MQ-2 sensor to detect gases related to fires, such as hydrocarbon gas. A 5 channel flame sensor is used to detect flames. The predetermined fuzzy logic rules will be used to control the fire extinguisher and implemented using the Arduino Atmega 2560 microcontroller as the brain of the system. Next, the microcontroller will send a control signal to the 12V DC pump output as a water spray system to deal with fires. The test results of this system show that the tool can detect early fire hotspots and respond well to fire extinguishing according to the fuzzy rule decisions carried out by testing the tool with 30 fire spots at different distances.
