This study was conducted with the purpose of understanding the relationship between the monetary value and emotion of architectural aesthetic. It is based on the results of an interactive survey of 800 citizens in five major metropolitan cities across the country. The relationship between emotional words for architectural aesthetic and monetary payment amount through contingent valuation method was analyzed using R-Studio, a big data analysis program, and the main research results are as follows: First, through the distribution of outliers by level of architectural aesthetic, it was confirmed that the monetary value increases rapidly as the level of architectural aesthetic increases. Second, it was found that people try to place more value on balanced and stable sensibilities, and place high monetary value on mysterious or progressive architectural aesthetic. Third, when cost issues are linked to architectural aesthetic, the intention for the construction itself plays a large role, confirming that economic and realistic aspects are strongly involved. Fourth, emotions that reduce the monetary value of architectural aesthetic include 'special', 'equivocal', 'strange', and 'complicated'. Fifth, emotional analysis based on architectural aesthetic score is more accurate than emotional analysis based on monetary value, and in studies related to monetary value, it is necessary to set the standard for architectural aesthetic score at 71 points. Sixth, it can be seen that innovative design, along with improving the aesthetic level, can be a strategy for improving the monetary value of architectural aesthetic. The results of this study can be used as a decision-making basis for architectural aesthetic emotional analysis, architectural aesthetic value estimation system development, architectural aesthetic emotional marketing, and place marketing strategies.

The Metaverse Model House(MMH) emerges as a marketing strategy in the Korean housing market post-COVID-19. Still in its early stages, MMH sparks ongoing studies. Recognizing that model houses drive actual purchases, it is necessary to approach MMH in order to derive a positive and satisfactory user experience. This study aims to investigate the user experience in MMH in the context of sensorial, interactive and informative experience, especially focusing on differences in groups. We conducted a survey of 83 users after experiencing MMH on a tablet PC. T-test and one-way ANOVA were conducted to identify statistically significant differences by demographic characteristics. Results revealed age-related distinctions in sensorial, interactive, and informative experience. Users in their 30s expressed negativity, citing a lack of presence and insufficient information. On the other hand, users in their 20s found enjoyment through avatar movement, while those in their 40s faced discomfort due to slow information acquisition. Users in their 50s experienced difficulties in understanding the operation methods and encountered operational errors. Therefore, based on these results, improvement directions for MMH were proposed.

The Ministry of Land, Infrastructure and Transport has actively advocated for nationwide adoption of BIM (Building Information Modeling) within the public sector, with the goal of integrating BIM throughout the construction life cycle. As the construction industry aligns with the paradigm shift of the Fourth Industrial Revolution, there is a growing demand for paperless digital collaboration to drive its ongoing digital transformation. However, the domestic construction industry still heavily relies on physical joint office spaces for large-scale projects. Decision-making processes in these joint offices typically involve face-to-face meetings, manual approval procedures, and extensive paper documentation, resulting in low productivity and efficiency. To tackle these challenges, there is a need to develop a BIM collaboration platform that adheres to ISO19650 information management processes and Korean CDE-based functional requirements. This study aims to identify essential functional requirements for the BIM collaboration platform through surveys and assess their practicality and feasibility. The research aims to lay the groundwork for developing a digital BIM collaboration platform tailored for the domestic construction industry.

The scope of this study focuses on Gosiwon residents in Seoul in 2023, with an initial survey population of 5,522 Gosiwons registered on the Seoul Open Data Portal. The methodology involved examining the current state of Gosiwons in South Korea, identifying limitations of existing regulations, analyzing similar studies and reports to prepare interview questions and survey materials, developing interview forms based on findings, and conducting face-to-face interviews using structured questionnaires. Fortunately, analysis of the living environment revealed that residents did not feel particularly vulnerable to risks such as aging or natural disasters. The average length of stay in Goshiwons was 2.34 years, with 27.9% of residents staying for over 3 years. On average, residents stayed for 4.11 years, with 55.4% extending their stays beyond the 3-year mark. Contrary to initial assumptions, this indicated that Goshiwons serve as long-term housing options. Recognizing Gosiwons as a viable housing option and exploring measures to enhance their role in housing are crucial, considering the rising trend in single-person households and the evolving purpose of Gosiwons, which are not legally recognized as housing.

This study originated from the recognition that, while design competitions are the typical method for commissioning designs for public architecture projects, attention to subsequent stages is crucial to fulfill the competition's ultimate intent. Survey results from both clients and designers underscored the importance of internalizing the initial project plan regarding construction cost and duration. Continuous research considering the characteristics and life cycle of public building projects is necessary to establish basic data, such as reference cases and type-specific standards. Additionally, there's a need to rationalize current price standards and period calculation methods for architectural design work, and to establish a basis for smooth operation by specifying design change work and various procedures during the architectural design stage. Ensuring smooth communication among project participants and a consistent project management system is vital. Moreover, understanding the public building project process from a collaborative perspective and forming a common understanding of roles and responsibilities is essential. By verifying primary participants' perceptions-clients and designers regarding changes throughout various project stages, this research underscores the need for systemic and academic improvements. The findings are expected to provide foundational data for future studies aiming to ensure rationality in post-design competition processes.

This study conducted a literature review on user experiences in COVID-19 medical settings in advance. Additionally, it summarized requirements from focus group interviews (FGI) concerning the architectural planning elements of the Modular Airborne Infection Isolation Ward. Consequently, the primary purpose of the modular facility and user needs based on patient severity were determined. Moreover, common planning issues and solutions, including facility usage, location & scale, space composition & circulation, equipment, and stress reduction environment, were organized as construction planning elements of the modular airborne infection isolation ward. The implications suggest that designing airborne isolation wards for mildly-to-moderately infected patients requires a different planning approach compared to high-risk infected patients, addressing the mismatched hard stay environment for relatively low-severity patients, which can stress both patients and medical staff. The modular infection isolation ward, leveraging modularity characteristics, should be adaptable to accommodate such distinctiveness and diversity.

This study explores the background behind the architectural features, especially the layout and composition, of the Buyeo Grand Shrine, renowned for its exceptional design among Japanese shrines. In the late 1930s, Japan promoted the construction of the Buyeo Grand Shrine on Busosan Mount as a commemorative project 2,600 years ago. Originally slated for completion in 1943, Japan invested significant resources in materials and labor. However, due to challenges in fundraising amid World War Two, the Shrine remained unfinished until Japan's defeat in 1945. The findings indicated that the architectural design of the Buyeo Grand Shrine was influenced by Japanese shrine styles from the mid-1930s. Bureaucratic engineers like Takashi Sunami actively introduced the Showa-jo style, prioritizing functionality to accommodate daily services, ancestral rites, and public worship. This approach involved connecting corridor transepts on the left and right sides to prayer recital and worship halls in the middle, inspired by the shinden style that arranged a group of buildings symmetrically, which was popular in Buddhist temples during the Momoyama and Kamakura periods. The layout and style of the Buyeo Grand Shrine resembled those of the Taiwan Grand Shrine, which held similar prominence among Japanese shrines during that era. This suggests a standardized architectural approach adopted by Japan for grand shrines during the era, reflecting the nation's architectural innovations and its religious and cultural aspirations.

This study explores the urban-architectural significance and effectiveness of temporary architecture along with its theoretical framework. It begins by examining avant-garde architecture from the 1960s and 1970s and the subsequent changes in era. Deleuze's philosophical concepts were employed to analyze avant-garde architecture and its correlations with temporary architecture. This study highlights the influence of avant-garde architecture on the emergence and expansion of temporary architecture. Furthermore, it reevaluates changes in contemporary temporary architecture since the 1980s and investigates examples with transboundary characteristics. Temporary architecture was classified into three main types: connection-oriented, re-territorialized, and de-centered, each with specific characteristics. Analysis revealed that attributes like rhizomatic, becoming, and virtualite played crucial roles in amplifying the dynamic nature of temporary architecture. Additionally, this study defined contemporary temporary architecture as one that actively interacts with various elements within and around architecture, including the urban environment, users, and programs. This discourse on the validity of temporary architecture offers a fresh perspective and contributes significantly to both research and practice in the field.

The purpose of this study is to evaluate the four goals presented in the guideline of the Urban Regeneration New Deal project, the contents of the business plan planned by each local government for the realization of these goals, and how the goals were achieved at the final stage of the current project. Eleven of the early urban regeneration New Deal projects selected in 2017 and 2018 were evaluated. These projects entered the final stage around 2023. Therefore, by evaluating the projects that are being completed at this point, it is possible to grasp the performance and meaning of the New Deal project. The four goals of the Urban Regeneration New Deal project are realization of housing welfare, strengthening of urban competitiveness, social integration, and job creation. Projects for social integration in the project planning stage are focused on strengthening residents' capacity, installing and operating urban regeneration field support centers, and community vegetable gardens. Unit projects for realizing housing welfare are focused on remodeling detached and multi-family houses, maintenance of alleys, and creation of parks and green spaces. Unit projects for job creation are focused on revitalizing the public economy, creating a new vitality hub space in the city center, and utilizing disfunctional spaces such as abandoned stations and closed schools. Projects to restore urban competitiveness are focused on resident-participatory greening and maintenance of neglected buildings such as abandoned and vacant houses. Among the various projects proposed by the guidelines of the Ministry of Land, Infrastructure and Transport, it turns out that the projects actually carried out in the field were very limited. In particular, in the course of this research, it was revealed that large-scale development projects, housing creation projects, job creation projects, and public enterprise-linked projects were relatively sluggish in the field implementation process. In contrast, the community capacity building program project, green space creation, and alley environment maintenance project were found to be very active projects.

During the final stages of community-based regeneration, this study explores the attitudes and conditions of the community regarding their level of involvement in the project. This study focused on a small-scale regeneration project in Pohang, emphasizing community participation, and the community's activities were analyzed. The investigation revealed that disunity within the local community, stemming from residential areas and social strata, significantly influenced both the direction and implementation of the project. The uneven distribution of involvement among residents not only fostered isolation and discord but also led to imbalanced facility placements. The challenges arising from community division and discord were prevalent in current policy directions, which prioritized indicators of decline over community attributes when selecting target areas. It is imperative to develop community regeneration policies that prioritize the inherent characteristics of communities, rather than relying solely on formal and physical factors that may not guarantee community cohesion.

Persistent condensation in residential spaces can lead to structural damage and mold growth, posing health risks to occupants. While existing studies focus on reducing condensation, there's a gap in research on condensation prediction. This study aims to explore the feasibility of a virtual sensor for condensation prediction using machine learning and data from prior studies. A high-accuracy virtual sensor model was developed and verified using condensation measurement data. Data preprocessing and Pearson correlation analysis were conducted, and input variables were selected through ReliefF evaluation. Indoor and outdoor temperature and humidity were chosen as final input variables. A prediction model was crafted using classification learning algorithms: Decision Tree(DT), Support Vector Machine (SVM), and Multi-Layer Perceptron (MLP). Validation of the prediction model was performed using Confusion matrix, Accuracy, and F-1 score. The accuracy of the virtual sensor model was 97.1% for Decision Tree, 98.5% for SVM, and 98.6% for MLP. The developed model is expected to effectively prevent condensation in residential spaces susceptible to surface condensation. Future work will focus on integrating virtual sensors into existing ventilation and air conditioning systems for practical application in residential spaces.

This study examines the potential use of coal gasification slag (CGS) as a fine aggregate in concrete mixtures, considering different combinations of cement types and mix designs. Test results revealed that concrete flowability increases with changes in cement composition and CGS replacement ratio, while reducing air content necessitates higher doses of air-entraining agent. The initial compressive strength of concrete is notably high with cement, with greater long-term strength observed in combinations involving binary or ternary blended mineral admixtures. However, a slight decrease of 1-5% in compressive strength is noted with an increased CGS replacement ratio. Durability fluctuations, mostly minor, vary with cement type, generally showing positive results associated with the CGS replacement ratio. Nonetheless, reduced frost resistance is observed only in the TBC+CGS 50% mixture, suggesting air content's predominant influence over CGS's impact on frost resistance. Overall, CGS use as a fine aggregate of up to 50% poses no adverse effects on concrete's comprehensive physical properties and durability. However, additional research is necessary to devise methods for maintaining optimal air content in CGS materials.
