With the implementation of the high school credit system in Korea, the role of "home base" spaces as informal communication and activity hubs has become increasingly important. This study aims to examine how different spatial types of home bases affect students’ perceptions, usage behaviors, and spatial demands. The research focuses on high school students as the main users and compares three schools in Busan, each operating a different spatial configuration: alcove, hall, and enclosed-room types. Data were collected through a questionnaire survey of 180 students and analyzed by comparing usage awareness, behaviors, and spatial, furniture demands across three home base types. The results showed distinct patterns: Alcove types were storage-centered, Hall types emphasized openness and interaction, and Separate-room types supported learning and group activities, with all schools demanding flexible and communicative spaces. In conclusion, home bases act as key hubs for informal communication, and design strategies should reflect spatial characteristics to better support diverse student needs under the credit system.

This study examines ways to improve welfare facilities in response to long-term population change through a case study on converting daycare centers into senior care facilities in Korea, where rapid population aging and declining birth rates are significant challenges. The research combines a theoretical review with field surveys and interviews. The findings identify key characteristics and directions for improvement. Most daycare centers are converted into elderly welfare facilities due to their structural similarity, which allows for efficient remodeling. Interior spaces are repurposed by converting nurseries and classrooms into living rooms and bedrooms, and teacher offices into administrative offices and nursing stations. Exterior areas are expanded from playgrounds into vegetable gardens, lawns, and parking areas. Heating and cooling systems are either replaced or reused, while ventilation, safety equipment, and emergency systems are upgraded to meet the needs of elderly users. Interview results indicate that selecting a daycare center requiring minimal structural modification is a critical factor in successful conversion. Major challenges in changing facility use include construction-related complaints, rising costs due to the installation of elevators and fire safety systems, and difficulties in securing specialized interior design firms for senior care facilities.

This study categorizes the architectural characteristics of diversified Autonomous Housing Improvement projects and identifies their implications. Based on 40 completed cases in Seoul, the analysis examined lot consolidation, compliance with street access requirements, and building integration. The findings indicate that projects in Class 1 general residential zones actively used floor area ratio relaxation through the provision of rental housing. Lots were most often consolidated along the north?south axis to reduce the impact of solar access setback regulations. Sites without street access adopted strategies such as road dedication, incorporation of road segments, or consolidation with adjacent accessible lots. Smaller building-agreement projects maximized residential floor area through shared cores, while larger projects subdivided their building masses to create better harmony with the surrouding urban context, often unifying materials and forms to achieve coherent streetscapes. Overall, the completed projects show diverse approaches to the use of small lots and highlights cases that aim to contribute more actively to the urban and public realm.

Daylighting plays a key role in improving building energy efficiency, supporting occupant well-being, and providing visual comfort. As research and technology advance, green building certification systems have increasingly adopted performance-based approaches to daylight assessment. This study compares the evolution of daylight evaluation criteria in G-SEED and LEED using a framework that considers building classification, evaluation methods, performance metrics, assessment conditions, and scoring structures. Official manuals and technical guidelines from multiple versions were analyzed to identify major changes and trends. G-SEED has traditionally relied on static metrics such as the Daylight Factor (DF), but the recently announced 2025 draft revision represents a major shift. The revision integrates daylighting into a broader visual comfort category and expands its application to all building types. In contrast, LEED has evolved from Daylight Factor?based assessments to dynamic simulation metrics, including Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE), with ongoing refinement of scope and point allocation. These findings highlight the need for G-SEED to adopt more rigorous, performance-based frameworks aligned with global best practices to improve environmental performance and support occupant-centered design.

Convertible wards operate as general wards under normal conditions and switch to negative pressure isolation wards during outbreaks of high-risk respiratory infections. Examples include Emergency Treatment Beds and Public Hospital Isolation Wards, but current standards focus only on minimum conversion requirements and often overlook ward efficiency and accreditation. This study compared facility standards for National Designated Isolation Beds, Emergency Treatment Beds, Public Hospital Isolation Wards, and general wards, and examined floor plans from nine hospitals with 300 to 500 beds. Findings showed that patient rooms in convertible wards offer about 66 percent of the area required for National Designated Isolation Beds. Anterooms are not always provided, which weakens isolation performance. Differences among standards reflected reduced infection control requirements as well as distinct arrangements of support spaces. Floor plan analysis grouped support spaces into convertible facilities such as PPE doffing rooms, maintainable facilities such as nurse stations, and facilities that must be closed during conversion such as shared toilets. These needs varied according to zoning, circulation patterns, staff access, and the movement of patients or caregivers. Based on these findings, the study recommends developing facility standards for convertible wards that unify general ward operation with the ability to convert to negative pressure isolation wards while supporting necessary program and layout changes.

This study examines generational cultural characteristics and differences in preferences for living environments in later life within Korea’s rapidly aging society. The concept of generation is redefined based on shared historical and sociocultural experiences, and the ways in which generational lifestyles and values shape perceptions of residential space are analyzed. Using a structured survey of four generational groups, Baby Boomers, Generation 386, Generation X, and Generation MZ, the study identifies distinct patterns in housing perceptions and preferences for later-life living environments. The findings show that younger generations tend to prefer independent and privacy-oriented housing, while older generations place greater value on community-oriented apartments that encourage social interaction and a sense of belonging. Although convenience, healthcare accessibility, and safety are important across all generations, attitudes toward communal spaces and social participation vary. These differences reflect diverse generational behaviors shaped by cultural and social change. The study offers both theoretical and practical contributions. Theoretically, it enhances understanding of generational culture in a super-aged society. Practically, it provides empirical evidence to support the development of diverse and personalized housing models tailored to generational needs. The findings suggest that future living environments for later life should prioritize personalization, flexibility, and cultural adaptability, supported by human-centered design and technological integration. This interdisciplinary approach can inform policymakers and planners in developing sustainable residential strategies that promote dignity and well-being across generations in the era of super-aging.

The purpose of this study is to analyze the evolution and characteristics of conservation management plans around the Seoul City Wall, focusing on the Gwanghui area from 2014 to the present. The study classifies subsequent management plans into four types and examines how the guidelines of the 2014 Comprehensive Plan for City Wall Village were reflected and transformed over time. Building permit data are also analyzed to assess how conservation-oriented policies were implemented in practice. The findings indicate that recent management plans continue to align with the overarching conservation framework established in 2014, while translating it into more practical and multi-layered strategies tailored to local conditions. Rather than the large-scale redevelopment initially anticipated, urban change over the past decade has largely followed conservation-oriented principles through urban management plans. However, despite the integrative intent of the master plan, implementation in the Gwanghui area reveals an increasing tendency toward fragmented and area-specific management approaches. By examining the intersection of conservation and development, this study provides insights into the limitations and future directions of conservation management in historic urban contexts.

This study explores the cooperative community housing model as an alternative form of housing production. Although cooperative housing has gained attention as a potential solution to diverse challenges, its actual implementation remains limited due to financial, institutional, and legal constraints. To address these problems, the research examines the Eunhye Cooperative Housing in Dobong-gu, Seoul, which was developed through a resident-led process emphasizing participation and self-governance. Through qualitative case analysis of meeting records, interviews, and project documents, the study traces the entire trajectory from planning and participatory design to construction and management. The findings reveal three core features: democratic governance, participatory design aligned with residents’ needs, and collective ownership ensuring stability and cohesion. These were enabled by social trust, collaboration with intermediaries, and selective institutional support. The case illustrates cooperative housing as a socially grounded alternative to profit-driven models, enhancing spatial and social sustainability while underscoring the need for policy and financial frameworks to expand its viability. It contributes to understanding how cooperative housing can reframe the relationship between citizens, architecture, and urban housing policy in contemporary Korea.

This study aims to construct an analytical framework that explains the interaction between older adults’ functional capabilities and their neighborhood living environment based on the Capability Approach (CA) and the Person?Environment Fit (P-E Fit) theory, and to identify differences in factors influencing the neighborhood living environment according to city size. Using the raw data from the 2023 National Survey of Older Koreans, a Structural Equation Model (SEM) was derived through Confirmatory Factor Analysis (CFA) and Bootstrap analysis. Based on this model, a Multigroup SEM was conducted to analyze the relationships among instrumental activities of daily living (IADL), accessibility, Neighborhood Satisfaction, Service Needs, and Life Satisfaction among older adults by city size. The results indicate that, regardless of city size, accessibility was a key determinant of Neighborhood Satisfaction; however, its direct effect on Life Satisfaction is negative, suggesting a more complex and indirect pathway through neighborho od-related perceptions. Furthermore, city-level differences were observed in the structural relationships among Life Satisfaction, Neighborhood Satisfaction, Service Needs, and IADL, highlighting the context-dependent effects of neighborhood environments on older adults.

This study examines the evaluative perspectives and criteria used in Seoul’s Artworks for Buildings Review and identifies the structural gap between the system’s public-art objectives and its actual deliberative practices. Nineteen rounds of review committee minutes from 2024 to 2025 were analyzed in reference to the Artworks for Buildings Review Evaluation Form used by the Seoul Metropolitan Government. The rubric was expanded into 16 analytical categories, and all deliberation statements were coded at the sentence level for statistical and content analysis. The review process prioritizes external factors such as formal aesthetics and visual harmony, while public-art values, including citizen accessibility, cultural engagement, site specificity, and contributions to the urban environment, receive comparatively limited attention. Review documents are heavily weighted toward formal and technical information, restricting the integration of public-oriented perspectives. Committee composition and procedures further reinforce visually centered judgments. On average, 9.7 artworks are reviewed per session, limiting in-depth consideration of individual proposals and encouraging appearance-focused decisions. These findings highlight the need to revise evaluation criteria, broaden review materials, and diversify evaluative perspectives in order to strengthen the system’s public-art orientation and better align practice with policy goals.
