## 2 Smart Cities and Quality of Life: A Brief Literature Review  
The smart city concept focuses on enhancing the competitiveness of local communities and urban areas by leveraging innovative technological advancements to improve the quality of life for citizens, offering more efficient public services, and fostering a healthier environment [3; 4; 5; 6]. By utilizing advanced technologies, data analytics, and digital innovations, smart cities aim to increase the efficiency of urban services, improve resource management, and ultimately elevate residents' quality of life [48; 49; 50]. Integrating Internet of Things (IoT) devices, sensors, and big data allows these cities to optimize infrastructure such as transportation, energy, and waste management, while simultaneously promoting sustainability and resilience. Studies conducted by [PERSON] and [PERSON] [51] and [PERSON] [52] have shown that satisfaction with QoL is positively correlated with contentment regarding one's location and urban living conditions. A growing number of studies suggest that satisfaction with quality of life, as well as its measurement and improvement, is closely linked to the features and initiatives of smart cities [41; 42; 43; 44; 45; 46; 47]. As cities grow more complex, it becomes increasingly important to address factors such as health, safety, education, and environmental quality to ensure the well-being of citizens. The use of real-time data in smart cities offers powerful tools for assessing key indicators of quality of life, enabling more responsive governance, better public services, and a more citizen-centered approach to urban planning. By aligning smart technologies with the needs and experiences of city residents, smart cities represent a forward-thinking approach to shaping and enhancing life quality in modern urban settings. [PERSON] et al. [53] evaluated the perception of quality of life in a smart city by analyzing key elements of citizen satisfaction in Curitiba, a city in Southern Brazil known for being livable, green, inclusive, and ranked among the world's ten smartest cities. Interviews with 400 residents identified four main QoL domains: socio-structural relationships, environ mental well-being, material well-being, and community integration. Although Curitiba is ranked as one of the world's smartest and most livable cities, residents still report low satisfaction with certain smart city features. A study by [PERSON] et al. [54] proposed sustainability and smart city indicators from the citizens' perspective, considering the local context. The results, validated through exploratory and confirmatory factor analysis, revealed that citizen satisfaction is primarily linked to factors such as health and safety, well-being, recreation, public transport, walkability, social inclusion, primary services, city attachment, and the environment. [PERSON] et al. [55] assessed and compared cities across various European regions based on residents' satisfaction with urban life quality. Utilizing 26 indicators across five categories, the research examined differences in smart performance and quality of life among cities in different European regions. By leveraging data from the Urban Audit Perception Survey, ANOVA and post hoc analysis, it revealed significant variations in perceived quality of life across these regions. [PERSON] and [PERSON] [56] examined Macao, a developing smart city, focusing on how smart city quality of life (SCQOL) domains affect citizens' attitudes and support for smart city development (SCD). A survey identified five SCQOL domains: smart environment, smart people, smart livelihood, smart economy, and smart mobility. The results showed varying influences on support for SCD and categorized residents into three segments: passive, neutral, and enthusiastic supporters. [PERSON] et al. [57] analyzed the impact of smart governance factors on quality of life within the context of smart cities. Conducted as a quantitative, descriptive study, it involved a survey of 829 residents from a city in Northeast Brazil.
