Urban resilience has become a key issue in sustainable urban development amid rapid urbanization, climate change, environmental pressures, and development imbalances. Although urban resilience and urbanization studies have each developed relatively systematic bodies of knowledge, comprehensive reviews of their relationship remain insufficient. This study examines the research trajectory, major themes, analytical perspectives, methodological approaches, and changing characteristics of studies on the relationship between urban resilience and urbanization. Based on literature from the Web of Science Core Collection, it combines bibliometric analysis, knowledge mapping, and interpretive review. Using CiteSpace, it analyzes publication trends, keyword co-occurrence, thematic clustering, temporal evolution, and strategic theme distribution. The results show that this field has developed around climate adaptation, ecosystem services, resilience framework construction, and sustainable urban development. Analytical perspectives have shifted from one-way influence analysis to interaction, coupling, and coordinated development, while methods have expanded from descriptive discussion to quantitative and spatial analysis. These findings clarify the field’s theoretical context, knowledge structure, changing trends, analytical orientations, and methodological approaches, and offer a basis for future theoretical and empirical research.

This study aims to analyze how the Sponge Urban strategy is implemented as a hydrological network structure across Jiaxing South Railway Station and its adjacent public spaces, and to reinterpret the station as a mediating, climate-responsive infrastructure within the urban water system rather than a mere transit hub. The research proceeded in three stages: deriving hydrological management criteria from China's Climate Action Plan and Sponge Urban guidelines; cross-analyzing these with the station's design documents and station-area development plans; and reorganizing the findings into a “Urban-Block-Axis-Street” spatial hierarchy through a Criteria-Design-Review framework. At the urban level, decentralized collection and a flooding corridor enabled peak-flow attenuation; at the block level, a variable-level wetland (-2.5m to +0.8m) with four typologies created an adaptive buffer; at the axis and street levels, a four-stage grid-based bio-swale and permeable green streets formed a linear infiltration network. The study concludes that the railway station functions as an active control node redefining transit–water relations, that variable spatial use is central to climate-responsive design, and that hydrological infrastructure should be planned as a continuous.

With the full implementation of the Zero Energy Building (ZEB) certification system in 2025, the importance of introducing and enhancing the performance of passive design elements has increased significantly. The indoor louver-type concentrating daylighting system is considered an important passive design strategy that can improve the quality of the indoor lighting environment, while simultaneously reducing lighting energy consumption. This study aims to analyze the effects of different reflective types of indoor louver-type concentrating daylighting systems—diffuse reflective and specular reflective—on the indoor lighting environment. Indoor illuminance, uniformity ratio, and daylight factor were adopted as evaluation metrics. The results show that, compared to the specular reflective type, the diffuse reflective type improved indoor illuminance by approximately 39% and uniformity ratio by around 18%. In addition, the daylight factor increased by up to 56%. These results confirm that the reflective characteristics of indoor louver-type concentrating daylighting systems have a significant influence on daylight collection performance and the formation of the indoor lighting environment.

This study aims to contribute to the safety and quality improvement of reinforced concrete piloti structures in the jeju island by analyzing the types of re-bar arrangement defects that occur during the construction of these structures through structural supervision. The scope of this study was limited to the reinforcement arrangement defects in transfer columns, transfer beams, walls and slabs of reinforced concrete piloti structures subject to structural supervision. The types of defects examined included re-bar development, beam main bar spacing, stirrups, tie-bars, slab opening reinforcement and wall U-bar arrangement. The conclusions reached from this study are as follows: (1) Defects for spacing between layers of main bars in beams appeared at 30 sites out of 44 sites, and these defects cause bending failure of beams. (2) Defects in the stirrups and tie-bars cause failure of members due to internal concrete fall and buckling of the main bars. (3) Defects were found to be 10 sites out of 44 sites for the development of the column main bar and 3 sites out of 11 sites for U-bar construction of the wall, and these defects cause the development failure of the re-bars. (4) Defects around the slab opening were found to be 2 sites out of 11 sites, and these defects cause cracks around the opening.

Urban infrastructure has historically operated as a primary engine of economic growth, facilitating rapid urban expansion while systematically externalizing ecological costs. This paper advances the concept of the Green and Blue Shift, a paradigm-level reorientation of infrastructural logics that positions ecological processes not as peripheral or ornamental, but as the foundational substrate of urban life. Rather than relegating nature to an aesthetic supplement, the Green and Blue Shift reconceptualizes infrastructure as a dynamic, living ecological system in which green (vegetated) and blue (water-based) networks constitute the structural and metabolic basis of urban environments. Drawing upon urban ecology, landscape urbanism, and theories of urban metabolism, the paper introduces the notion of Supernature as a theoretical lens through which cities may be understood as hybrid socio-ecological systems. This framing challenges the entrenched dichotomy between the built and the natural, arguing instead for their co-constitutive integration. Through historical analysis, conceptual synthesis, and engagement with applied research evidence, the paper contends that contemporary ecological crises—climate change, biodiversity loss, and resource depletion—demand a fundamental transformation of infrastructural paradigms. This transition must shift from linear, extractive systems premised on throughput and accumulation, toward regenerative, networked frameworks that prioritize resilience, reciprocity, and ecological continuity. In doing so, the paper contributes a conceptual foundation for ecological urbanism, situating it within broader debates on sustainability and post-anthropocentric design while critically interrogating the normative assumptions that have historically underpinned infrastructural development. Furthermore, the study explicitly positions itself as a bridge between theoretical critique and design-oriented application. While acknowledging the limitations of a literature-based conceptual study, it establishes a theoretical basis and proposes concrete directions for future empirical, methodological, and practice-oriented research. Ultimately, by foregrounding ecological processes as infrastructural logics, the Green and Blue Shift reframes urbanization itself as an ecological project, thereby opening new pathways for reimagining the relationship between cities, nature, and planetary systems.

To contribute to the development of age-friendly cities in South Korea, which has entered a super-aged society, this study systematically analyzed trends in academic research regarding the physical environment accumulated in the fields of architecture and urban planning from 2010 to 2025. The 36 detailed physical environment checklist items from the WHO Age-Friendly Cities guidelines were utilized as the analytical framework. The results indicate a surge in research since 2017, aligning with the policy demands of local governments. Research subjects exhibited a dual structure, polarized into “mixed” research addressing the city as a whole and research focusing on specific spaces. In terms of research types, research on the development of planning principles and tools accounted for the highest proportion. The analysis by WHO checklist item confirmed that while research was concentrated on key items such as greenspaces and walkways, safety, roads, and design, areas such as transportation service operations and housing retrofitting and maintenance were identified as gaps with relatively insufficient research. This study confirms that domestic research has focused on single-facility improvements and hardware-centric approaches, lacking integrated perspectives at the living-sphere network level. Accordingly, this study suggests that future research must shift toward practical directions that integrate hardware and software and ensure organic connectivity centered on the living sphere.

This study aims to analyze interference issues occurring in program management environments of large-scale urban development projects and to propose a tailoring-based program management process for their effective management. A total of 528 interference cases identified during the program management of the Sejong Administrative City development project were analyzed, focusing particularly on site development works and their schedule delay factors. The results indicate that most interference issues occur during the planning and design stages, and the average construction duration of site development projects was delayed by approximately 27 months compared to the planned schedule. Based on these findings, a tailoring-based interference management process derived from the PMBOK 7th edition framework was developed. The validity and practical applicability of the proposed process were verified through expert surveys and case application analysis. The results suggest that the tailoring-based management process can effectively manage interference issues in program management environments and improve overall project performance.

This study examines six early houses designed by Charles Gwathmey between 1965 and 1970, aiming to clarify his design foundations by identifying the spatial principles that repeatedly structure architectural experience. It considers Gwathmey’s relationship to Le Corbusier’s promenade architecturale and section-based approaches to vertical organisation, analysing the plans, sections, and elevations of each house. Focusing on the public area organised around the double-height living room, the analysis (1) identifies key points along the approach sequence where gaze and direction shift, and (2) examines modes of vertical connectivity that enable the simultaneous perception of upper and lower levels. The findings indicate an organic system of circulation transitions and an experiential order in which the double-height living room operates as the core. These principles are expressed externally through simple geometric compositions and solid–void contrasts focused on the living-room opening, confirming an integrated spatial language across plans, sections, and elevations.

This study focuses on Design for Manufacture and Assembly (DfMA)–based construction as an innovative approach to addressing the productivity decline and safety challenges currently faced by the construction industry. Through a comprehensive literature review, the study clarifies the concept of DfMA, its design principles, and its effects on construction processes, quality, and safety. In addition, international policy cases and expert surveys were analyzed to assess the current level of domestic adoption and to identify key constraints to its implementation. The findings indicate that DfMA has substantial potential to shorten construction duration, enhance quality, and improve safety by incorporating manufacturing and assembly considerations at the design stage. However, its widespread adoption in Korea is hindered by limited manufacturing infrastructure, fragmented procurement systems, insufficient digital capabilities, and regulatory inadequacies. While the private sector has increasingly applied DfMA, primarily in small-scale modular housing projects, public-sector adoption remains constrained by institutional limitations. Based on these findings, the study proposes policy measures including the development of specialized manufacturing firms, establishment of regional production hubs, expansion of DfMA-oriented public pilot projects, introduction of integrated procurement and delivery models, revision of building standards, and enhancement of industry and public awareness. These measures are expected to facilitate a transition toward a manufacturing- and assembly-oriented construction paradigm and to contribute to the development of a more sustainable construction ecosystem.

This study investigates the structural conditions shaping the reuse of small abandoned railway stations. A total of 37 cases of small-scale abandoned stations on conventional railway lines in Korea were analyzed to identify patterns of reuse and the spatial factors influencing their formation. First, reuse cases were categorized into five program-based case groups according to their spatial utilization characteristics. Next, six conditional variables were defined to represent the physical resource conditions and socio-operational contexts of each station: railway infrastructure, landscape resource, architectural heritage, community relationship, operational structure, and accessibility. Based on these variables, a hierarchical cluster analysis using Ward’s method was conducted to explore the structural patterns underlying the reuse of abandoned stations. The results indicate that the reuse of abandoned stations is not merely the outcome of arbitrary program selection, but rather a structural phenomenon shaped by the interaction between physical resource conditions and socio-operational contexts. Different combinations of these conditions lead to distinct spatial reuse structures, such as Resource Expansion Type, Outdoor-Oriented Type, Heritage-Oriented Type, Community-Integrated Type and Market-Driven Type. The findings suggest that effective strategies for the reuse of abandoned railway stations should begin with a systematic assessment of spatial resources and contextual conditions rather than focusing solely on programmatic conversion.

This study aims to analyze and classify the declining characteristics of residential areas by integrating physical indicators, locational-economic indicators, and de facto population, and to propose differentiated management strategies based on the typology. The analysis focuses on residential areas in the “dong” districts of Jeju Special Self-Governing Province at the census tract level, using indicators such as undersized parcels, aged buildings, building structure (measured as a ratio), official land price, and de facto population. The results show that the characteristics of residential decline are shaped by the combined effects of physical conditions and regional activity levels, and can be classified into three types: central activity type, declining residential type, and planned residential type. Furthermore, even when the same indicators are applied, the characteristics of each type vary depending on the spatial structure of the city. These findings suggest that residential area management should move beyond uniform approaches and adopt differentiated strategies that reflect the specific characteristics of each area.

This study investigates the effect of fiber type on the flowability and mechanical properties of cementless fiber-reinforced composites using a calcium hydroxide-ground granulated blast furnace slag (Ca(OH)2-GGBS) binder system. Four fibers, jute, nylon, polypropylene (PP), and polyvinyl alcohol (PVA), were incorporated at a constant volume fraction of 2% under identical matrix conditions. The binder consisted of GGBS and Ca(OH)2 at a ratio of 0.92:0.08, and both the sand-to-binder ratio and water-to-binder ratio were fixed at 0.30. Slump-flow, compressive strength, direct tensile, and shear tests were conducted to evaluate the fresh and hardened performances of the composites. The results showed that fiber type significantly influenced both flowability and mechanical behavior. PP and nylon mixtures showed relatively high slump-flow values of 695 mm and 691 mm, whereas jute and PVA mixtures showed lower values of 631 mm and 613 mm. The compressive strength ranged from 37.54 to 44.92 MPa, with the nylon mixture showing the highest value. In direct tension, the PVA mixture exhibited the best post-cracking behavior, with a first cracking stress of 3.89 MPa, a tensile strength of 5.45 MPa, and a tensile strain of 4.60%, accompanied by multiple microcracking. In contrast, the jute and PP mixtures showed little or no stress increase after first cracking, while the nylon mixture showed only limited post-cracking tensile response in some specimens. In shear, the PVA mixture showed the highest shear strength of 9.27 MPa, whereas the other mixtures showed similar values ranging from 5.52 to 5.71 MPa. These results indicate that PVA fiber is the most effective for improving the tensile and shear performances of the Ca(OH)2-GGBS-based cementless composites.
