The Mangyang-ro hillside residential area is a distinctive neighborhood where Busan’s historical context and topographical conditions intersect, creating a diverse mix of residential types. More than a residential space, the area represents a typical hillside neighborhood that reflects the daily lives of Busan’s residents and the city’s urbanization process. However, recent population decline and deteriorating living conditions have placed the area at risk of disappearance, underscoring the urgent need for preservation. This study identifies the organizational components of the Mangyang-ro hillside residential area by classifying it into 51 hillside residential clusters based on land type and road layout. Within these clusters, residential types were further grouped into three categories to quantitatively analyze organizational components and identify their characteristics. The findings offer valuable baseline data to support the development of sustainable preservation and management strategies for hillside residential areas

This study examines structural inefficiencies in Korea’s system for realizing design intent in public architecture. Focusing on the operational framework of the Seoul Metropolitan Government, the research identifies key regulatory and administrative gaps and proposes standardized criteria for defining the scope of work and establishing an appropriate compensation model. Through a comparison of fixed-percentage and cost-plus-fee methods, the study shows that a transparent compensation system based on actual work input strengthens accountability and improves quality by ensuring active architectural involvement during the construction phase. The findings offer a practical framework for enhancing the quality of public architecture and for expanding institutional improvements across the country and into the private sector. Ultimately, the research aims to strengthen the professional role of architects by presenting an equitable, actionable policy model for achieving design intent.

This study analyzes statutory revision opinions derived from interpretations of the Building Act between 2011 and 2023, focusing on their implementation outcomes and characteristics. Approximately 40 percent of the opinions were reflected in legislative amendments, and 95 percent of the adopted opinions were revised within three years. The category labeled Requiring Clarification showed the highest implementation rate, while Proposing Policy Need Review demonstrated lower implementation due to the need for additional policy judgment. Most adoptions occurred through Detail Addition, whereas revisions communicated only through the Operational Guidelines Issuance showed limitations in public accessibility. Analysis of unimplemented cases identified provisions associated with MOLIT Improvement Plans, Legal Revision Needed, and cases in which maintaining the existing statute was more appropriate. Although statutory revision opinions contribute to improvements in the Building Act, the proportion of unimplemented items indicates the need for ongoing monitoring and stronger coordination between the Ministry of Government Legislation and the Ministry of Land, Infrastructure and Transport.

The Buy to Rent Public Housing (BRPH) Program, launched in 2004, has been in operation for more than two decades, leading to a growing number of aging housing units. To address this, the Public Building Remodeling Program was created to improve physical conditions through reconstruction and renovation. However, the sharp rise in construction costs after the COVID-19 pandemic has made implementation increasingly difficult. Off-Site Construction (OSC) methods, known for being more cost-efficient than conventional reinforced concrete (RC) construction, have gained attention and are now used more frequently in public housing projects. OSC relies on a dual-structure process in which modular units are produced in factories and then assembled on-site, making transportation and lifting operations essential to project feasibility. BRPH sites, however, differ greatly from typical OSC project environments. While many OSC projects are placed in newly developed urban areas with low building density and wide road access, BRPH sites are often located in older, densely built districts with narrow roads and limited space. As a result, applying OSC methods in these areas requires customized transportation and lifting criteria. This study identifies transportation and lifting standards for three OSC construction types by analyzing modular housing cases of similar scale. These standards were applied to deteriorated BRPH sites in Seoul. The results show that although steel VMM and concrete PMM modular units work well for apartment-type housing, their suitability for BRPH remains limited. The findings highlight the need for OSC modular units specifically tailored to the spatial and logistical conditions of BRPH.

The Role of Small Stores in Developing Community-Integrated Care for Older Adults

South Korea has experienced unprecedented economic growth through modernization and industrialization. Despite these achievements, many older adults have been marginalized by newly developed services and unfamiliar urban spaces, leading to social isolation, economic hardship, and limited access to places for daily social engagement. This study examines the social roles of small local stores in supporting community-integrated care for older adults through a review of existing research literature. Small stores can function as social spaces where older adults are able to visit, remain, and interact, helping to counteract the alienation produced by market-driven urban development. Carroll’s framework of Corporate Social Responsibility is used to analyze these roles. Stores fulfill economic and legal responsibilities by providing local economic activity, employment, and compliance with regulations. They also perform ethical and philanthropic roles, such as maintaining long-term relationships with neighborhood residents and offering meals or informal support to customers and neighbors. In some communities, small stores already serve as social hubs where older residents gather, share resources, and support one another. These functions contribute to the formation of local care networks that connect residents with welfare services, medical care, and social agencies. However, small stores face significant challenges in sustaining operations amid intense competition from large-scale retailers and corporate specialization. In a rapidly aging society with limited social services, the social roles of small stores require recognition and preservation. Although previous efforts, including social franchising and government support, have aimed to sustain small businesses, market-driven development continues to displace them. Given their potential contribution to community-integrated care, enhanced and innovative support is necessary to sustain socially oriented stores or to embed these social functions within new retail models serving older adults.

https://doi.org/10.5659/JAIK.2026.42.2.57

This study analyzes trends in academic research on multifamily housing management in South Korea from 2000 to 2024, focusing on social integration and related socio-institutional factors. A total of 104 studies were reviewed by period, research topic, and management type. The results show a marked increase in research activity after 2010, aligning with institutional reforms such as the enactment of the Multi-Family Housing Management Act and evolving policy discussions on urban regeneration and inclusive housing. Recent studies have placed greater emphasis on policy analysis, community formation, and social mix strategies, while topics such as conflict mediation and participatory governance remain less developed. The management focus has gradually shifted from physical maintenance to more integrated approaches that incorporate social and hybrid strategies, reflecting a broader view of multifamily housing as a platform for community building and social inclusion. Future research is encouraged to adopt qualitative and comparative approaches to better capture diverse housing contexts and to promote integrated management strategies that balance physical infrastructure with social coordination.

A Study on Quantitative Methods for Diagnosing Damage in Wooden Architectural Heritage

최현서(Choi, Hyeon-Seo) ; 김윤상(Kim, Yun-Sang)

https://doi.org/10.5659/JAIK.2026.42.2.69

This study develops a quantitative framework for assessing damage in wooden architectural heritage by proposing a damage mapping system and evaluation method. Research materials included an outdoor experimental model in Wanju, Jeollabuk-do, and three national survey reports published in 2022 by the Cultural Heritage Administration and the National Research Institute of Cultural Heritage. The experimental model was used to identify early-stage damage patterns, while the reports provided insights into long-term and complex deterioration. Based on these sources, a damage map was created incorporating wood-specific categories, such as insect damage and decay. Quantitative evaluation was conducted by overlaying grid units to calculate damage ratios. Among the grid sizes tested, 50 mm, 10 mm, and 5 mm, the 10 mm unit proved most effective, balancing accuracy and efficiency. Application to Geungnakbojeon Hall of Muwisa Temple in Gangjin confirmed the method’s practical validity, showing only a 0.46 percent deviation compared to measured data. This approach complements conventional survey methods, which often rely on subjective judgment, by providing a more objective and applicable system for the conservation and management of wooden heritage.

This study presents a data-driven framework for developing flexible housing based on daily-cycle scenarios, addressing the changing lifestyles of the rapidly increasing number of one- and two-person households. To move beyond earlier research that focused mainly on lifecycle stages or floor-plan variations, the study uses the 2024 Time Use Survey microdata from Statistics Korea to analyze daily behavioral patterns and establish a step-by-step relationship among behavior, scenario, space, and technology. Four persona types were identified through this analysis. Two representative groups, a young single professional in their 20s and a retired senior in their 60s, were selected to clarify key time-based activity patterns and the spatial transitions needed to support them. Throughout this process, flexible technological elements such as sliding, lifting, and rotating mechanisms were mapped to behavioral changes, demonstrating that these adaptive features can effectively reduce functional conflicts such as work and sleep or cooking and leisure, which are common in compact housing. Overall, the framework combines behavioral data analysis with technical design to support next-generation, human-centered models that enhance the flexibility and efficiency of small urban housing.

A Study on the Characteristics of Demolished Architectural Assets and Criteria for Priority Review

윤혜영(Yoon, Hye-yeong)

https://doi.org/10.5659/JAIK.2026.42.2.91

This study examines the characteristics of demolished architectural assets to identify factors associated with a higher risk of demolition. Key factors contributing to asset loss were identified through a review of existing literature, followed by systematic monitoring of 492 architectural assets designated by Incheon Metropolitan City in 2018. Among these, 27 demolished assets were analyzed in detail. The findings indicate that demolition risk is significantly higher for privately owned assets, those located in urban regeneration or redevelopment areas, and those with a single historical or design value rather than multiple, overlapping values. Assets with these characteristics should therefore be classified as high-risk and given priority in preservation efforts. Although the Act on the Value Enhancement of Hanok and Other Architectural Assets lacks direct regulatory mechanisms to prevent demolition due to conflicts with private property rights, architectural assets remain important historical and creative resources. Stronger policy measures are needed to support their long-term preservation and active use.

In each region, traditional housing has been transformed into a current housing shape, reflecting industrial materials and technologies since the Industrial Revolution in the West. In the case of Japan, unlike China and Korea, it has gone through an autonomous housing modernization process and has a unique residential culture to date. This study analyzed the characteristics that appeared in the process of housing modernization in Japan from an extension of Japanese tradition, and conducted a survey of Korean experts on the works that won the Japanese New Architect Award to derive and verify the characteristics through image language analysis of Japanese houses. As a result of the study, it was intended to synthesize and refer to the characteristics of Japanese housing, expression methods, and architectural meanings that have continued to appear through the modern period in traditional Japanese housing..
