Among the various factors that shape housing, psychological factors are emerging along with physical factors. Accordingly, this study sought to examine residential environmental factors that influence the formation of place attachment in young single-person households living in the metropolitan area. For this purpose, survey items for place attachment and residential satisfaction were established through previous research, and a total of 265 copies were used in this study. The research results based on this are as follows. First, young single-person households generally think positively about their housing and tend to form attachments. However, due to the nature of single-person households, the difficulty in coping with emergency situations was the greatest, and along with economic difficulties, they felt greatly lonely. Second, as a result of the perception of young single-person households' residential satisfaction and place attachment measurement items, they positively perceive the narrow scope of their home and surrounding environment, but their sense of community, such as relationships between neighbors, community participation, and sense of belonging is low and quite lacking. Third, we looked at the residential environment factors that influence each place attachment component (place identity, place dependence, place fixation, and place emotion). Through this, it was found that young single-person households were influenced more by the various infrastructure facilities of the residential environment, abundant green space, and a convenient and clean environment for living, rather than by the condition or quality of the housing.

Unlike large-scale apartment complexes composed of multiple buildings, stand-alone apartments typically refer to single buildings with fewer than 300 units. These are interspersed within Seoul's urban fabric and exert various influences. However, most previous studies have focused on large-scale complexes, leaving a gap in research on stand-alone apartments from historical, socio-cultural, and urban morphological perspectives. This study examines the locational patterns and diffusion processes of stand-alone apartments in Seoul over the past half-century, analyzing their morphological characteristics from urban and architectural viewpoints. The development history of stand-alone apartments was analyzed in phases according to changes in construction volume and regulations. Construction began in the 1960s, surged in the 1990s, decreased in the 2000s due to stricter regulations, and saw changes in the 2010s reflecting infrastructure considerations. The established database revealed the morphological characteristics of stand-alone apartments. From an urban dimension, their locations and spatial distributions were mapped based on completion years. From an architectural dimension, the physical attributes were analyzed, including site area, plot and surrounding road patterns, building form and size, and ancillary welfare facilities. Historically, stand-alone apartments have been perceived negatively due to their haphazard construction without systematic urban planning. However, recently there has been a trend towards more thoughtfully designed stand-alone apartments that consider existing urban environments, socio-cultural factors, and transportation infrastructure. These small-scale, high-density developments can accommodate a high number of units on smaller plots and have the potential to become a viable urban housing type with systematic planning. This study provides a foundation for future research on the development directions for stand-alone apartments.

Today, it is necessary to change and improve the space of the university library, which is classified as a core facility in the university according to the constantly changing resources in the university. Therefore, it is necessary to present correct and specific directions for university library space re-planning(remodeling) along with case analysis of changes in university library space. Accordingly, the purpose of this study was to compare changes in internal spatial composition before and after remodeling targeting Central Library of Chungbuk National University in 2018. The research method first, the concept of the university library and the flow of change were reviewed, and the spatial components of the university library were divided into three categories. And then, the background and requirements of the expansion of the Central Library of Chungbuk National University and the changes after the expansion were reviewed, and a comparative analysis of the plan before and after the expansion was conducted through the VAE. The conclusion is as follows. 1)Central Library of Chungbuk National University has been transformed into a simpler but more specialized university library space since remodeling. 2)Central Library of Chungbuk National University has been able to manage space efficiently without significant changes and movement of rooms, even though it has grown in size due to remodeling and expansion. 3)Central Library of Chungbuk National University has its own architectural, spatial characteristics due to remodeling. This Study is intended to help present the concept of basic space re-planning(remodeling) of university libraries as an active reference example for the space arrangement and extension methods of university libraries needed today.

After liberation, Jeju experienced significant transformations in its industrial structure and residential environment, driven by domestic and foreign investments under central government development policies. These changes led to the emergence of new building types alongside traditional Jeju architecture. To understand modern buildings in Jeju, it is essential to examine how urban and architectural developments evolved over time in response to social changes. This study provides a foundational analysis of these shifts, summarizing the changes in buildings and architecture from liberation until 1988 through a literature review. Utilizing data from the Jeju Basic Architectural Asset Survey, the study involves processing and reclassifying information, then analyzing it with ArcGIS and SPSS23. By focusing on the link between social changes and architectural evolution, this research examines the characteristics of building use, scale, structure, outer wall materials, roof materials, and shapes over different periods. It also analyzes the architectural asset values. The findings revealed that since liberation, Jeju's architecture has evolved significantly in connection with broader societal changes.

This study evaluates 38 senior centers in Gunsan City to provide data for improving leisure facilities for the elderly. Analysis of floor plan configurations shows a trend toward open space designs in recently built or renovated centers. While universal design is increasingly included in new or updated facilities, older centers face challenges due to physical constraints, particularly at entrances, where improvements are essential for better accessibility. Demographic analysis revealed that most users were women aged 80 and older, and these centers were not attracting a broader range of elderly participants. Survey data from users strongly support reconfiguring senior centers into multi-generational facilities. Alongside modernizing outdated infrastructure and equipment, these centers could be repurposed as communal spaces for multiple generations, including the current elderly population. While this study highlights the needs of current users, future research should explore the leisure and welfare needs of elderly individuals who do not use senior centers, as well as the middle-aged population who will soon enter this demographic.

The number of Dahamkke Care Centers (hereinafter referred to as out-of-school elementary care facilities) nationwide, which was 10 in January 2018, increased significantly to 1,046 as of January 2024. Nevertheless, academic research on the spatial organization and architectural planning of out-of-school elementary child care facilities by function is insufficient. Accordingly, in this study, the convergence type "Wooridongne Kium Center," an out-of-school elementary care facility operated by the Seoul Metropolitan Government, was selected as the research object and the spatial composition of the out-of-school elementary care facility by function was analyzed. In addition, accessibility in space for each function was analyzed using the integration value. The space configuration for each function of an out-of-school elementary care facility requires five space groups: common space, activity space, management support space, hygiene space, and other spaces. The degree of integration of space by function was in the order of common space, activity space, management support space, other space, and hygiene space, and it was analyzed that the common space and activity space were in the main location. This is interpreted to mean that child care activities are concentrated in common spaces and activity spaces, so accessibility in the two space groups is considered important. Through such research, it can be used as basic data for the architectural plan and design of Seoul's integrated elementary care facilities and out-of-school elementary care facilities with similar area sizes.

This study aims to develop and validate a model to measure the degree of visual privacy in detached collective housing through visual analysis. This type of housing has emerged to respect individual privacy while also reinforcing community connections. Although these homes create strong visual connections between units and with exterior spaces due to their openness, they may compromise privacy by leaving units visually exposed. Therefore, a tool is needed to measure the level of visual exposure in these housing types. The common Isovist analysis, which is a standard visual analysis method, does not account for territoriality and often focuses on one's own space and area rather than considering others' spaces. To address this issue, this study excludes the analysis of one's own space. By conducting visual analyses of two cases of detached collective housing, Moriyama House and Seijo Townhouse, the model was tested for its effectiveness in considering privacy. The analysis revealed that both cases feature open indoor spaces visible from the outside, but Seijo Townhouse appeared to be more effective than Moriyama House in controlling privacy.

This study addresses the complexity of architectural laws and regulations and their administrative burden, focusing on improving efficiency in the interpretation and query-response processes using large-scale language models. The research centers around the development and implementation of the SPARC (Semantic Processing for Architecture Regulation Compliance) engine, primarily utilizing data from inquiries and complaints submitted to the Ministry of Land, Infrastructure, and Transport regarding architectural laws. This prototype system is designed to augment reference information necessary for legal interpretation, and its effectiveness was validated through a quality assessment of system responses to actual complaint data. The results show that the system achieved an accuracy rate of over 80% for general inquiry complaints with clear conclusions and 70% to 100% for more complex cases requiring legal interpretation by the legislative affairs office. This research represents the first attempt to apply AI in the field of regulatory administration, providing a critical technical and policy foundation for the development and operation of AI-based systems for interpreting architectural regulations.

Growing awareness of the climate crisis, driven by carbon pollution and material overconsumption in construction, has sparked interest in sustainable building materials. This has led to research on materials that support carbon circulation, with a particular focus on algae, a natural and renewable resource. This study examines the architectural application of algae-based bioplastics by analyzing precedent cases where algae has been used as a biomaterial alongside additive manufacturing techniques. The research specifically explores Fused Granular Fabrication (FGF), a 3D printing method suitable for producing algae-based bioplastics at an architectural scale. By experimenting with various types of bioplastics derived from waste algae, the study assesses the feasibility of creating architectural elements such as columns, parametric curved surfaces, and mesh structures. The findings highlighted the potential of digital fabrication methods using algae-based bioplastics and proposed three specific manufacturing techniques: Planar 3D Printing, Non-planar 3D Printing, and 3D Printed Formwork.

This study investigates the problems of the BIM design method of Korean architecture firms by examining the internal BIM organizations and the role BIM managers when carrying out architectural design projects in Korea and the United States. Both countries introduced BIM at the same time, but Korean architecture firms have been handling BIM-related tasks through internal or external BIM organizations or BIM managers. This method is hindering the spread of BIM and causing a shortage of experts. In contrast, in U.S. architectural firms, BIM managers are in charge of technical advice, education, and initial setting so that all team members can build know-how to use BIM. This study aims to visualize the interaction, influence, dependence, and connectivity among team members within the design organization by analyzing social exchanges, common perceptions, and networks collected through a survey of team members of architectural design projects conducted by BIM in Korea and the United States. The strength of exchanges between team members was measured by identifying the number of people and the frequency of interaction used in each task, including the BIM organization and the BIM manager. Furthermore, the centrality of the organizational network was determined through the mutual dependence on work among team members within the BIM organization. Compared to BIM projects in U.S., Korea's BIM projects exhibited more frequent exchanges between team members, but the BIM organization and design organization were separated, and the BIM manager was solely in charge of their connection. In all of the U.S. architectural firms surveyed in this study, there was no separate BIM organization, and the role of the BIM manager was to assist the project team from the peripheral rather than the center of the team's network. In order to spread and revitalize the BIM design method in Korean architectural firms, it is expected that BIM organizations and BIM managers will avoid the role of exclusively managing BIM work to acting as an integrated design tool for all team members to share BIM design experience and know-how.

This research explores the roles of monuments by examining two controversies: the Gumi Export Monument and the Monument of the 50th Anniversary of the Gumi National Industrial Complex. Since its erection in 1976, the Gumi Export Monument has served as a gateway to the complex but is often seen as an obstacle causing traffic accidents and congestion, sparking ongoing debates about its removal. The second controversy involves the omission of Park Chung Hee's name, the founder of the complex, from the anniversary monument. This raises questions about what should be commemorated. The polysemy of concrete, the material used in the Gumi Export Monument, plays a crucial role in evaluating its value. The second controversy also highlights a shift towards individualized commemoration, reflecting a broader social change toward accepting diverse opinions. These controversies underscore monuments' fundamental role as repositories of memory, continually reminding society of the past and prompting reevaluation.

The exact timing, purpose, and nature of the construction of Chimgwaejeong have not been well known about the needle thread. Looking at the transition process of Chimgwaejeong, 1870 and 1926 are important inflection points. The appearance before 1870 is presumed to be a left-right symmetrical floor plan in the center of the three-compartment room in the center of the room in the plan, as it has a left-right symmetrical elevation around the center of the room in the case of elevation. It is believed that it was changed to a four-compartment floor plan during the overall reconstruction in 1870. However, there is an important clue that the original shape was restored in 1926, and it is presumed that the current four-compartment room plane remained the same, the walls of the rear compartment disappeared, and the floor was installed. After that, there was no significant change until the 1950s, and it seems to have been changed to the shape of a government office such as Yeonmugwan during the renovation in 1970 and reached the present day.

The Gisa Jinpyori Jinchan was a banquet held during the regency of Crown Prince Hyomyeong, between the reigns of King Jeongjo and King Sunjo. This study examines the architectural characteristics of the royal palace stage repairs and installations in the early 19th century. Unlike the vertical stage configurations of the 1795 Bongsudang Jinchan and the 1827 Jagyeongjeon Jinjak, the Gisa Jinpyori Jinchan featured a horizontal arrangement, with Gyeongchunjeon Hall at the center and Bogye positioned symmetrically on both sides. Gyeongchunjeon faced east, while Bogye was placed to the west, creating an ambiguous entrance and exit, yet maintaining balance by positioning Bogye on either side of Gyeongchunjeon. Hyegyeonggung's seat was located in a room south of Gyeongchunjeon, with the queen dowager and queen seated separately to the east of the main hall. The king's seat was placed to the west, and the queen dowager's to the east, organizing the palace interior. The king and queen's seats in Bogye were separated from the queen dowager's to reflect their ranks. In the Gisajinchan, the king's quarters were in Seobogye, while the royal women's quarters were in the smaller eastern main hall. The plain table in front of the king and queen's quarters is a distinctive feature of the Gisajinchan. The absence of the pyopibangseok, the highest-ranking seat used at the 1795 Bongsudang Jinchan, suggests that Sunjo's youth delayed its installation until he began his political duties. The Gisa Jinpyori Jinchan's stage is the only historically documented royal stage with a horizontal structure, centering on the main hall and bordered by guardrails, in contrast to the vertical structure of other events. This unique design, structured to suit the main hall's layout with Gyeongchunjeon at its core, holds significant importance in architectural history research.

This study explores the plan to construct the Buyeo Grand Shrine, a significant project initiated by the Japanese Government General of Korea in the late 1930s. Governor-General Minami Jiro emphasized that, alongside the shrine's construction, the surrounding area known as the God's Garden should be developed into a unified space that reflects the historical relationship between Japan and Korea. Due to its importance, Takanori Hongo, who had previously led the creation of divine garden parks in Japan after the Meiji Jingu Shrine, played a key role in developing the God's Garden at Buyeo Grand Shrine. Hongo, drawing on his studies in Germany, introduced German forestry and ecological theories, promoting the cultivation of local vegetation and succession by planting trees suited to the region's climate. He advocated for maintaining the God's Garden as a natural forest with minimal human intervention over time. The Buyeo Grand Shrine incorporated German tree-planting techniques into the design of God's Garden, following the Meiji Jingu model introduced by Japanese scholars who had studied in Germany. Although modern ecological theories were applied to create a natural forest, this effort was disconnected from the goal of creating a landscape representative of all Korea. In fact, while promoting the architectural style of Buyeo Grand Shrine, the Japanese government pushed for the adoption of a Joseon-style divine shrine, aiming to introduce a universal East Asian architectural form. Ultimately, the Buyeo Grand Shrine appears to have been a rhetorical tool designed to deceive the people of Joseon, driven by imperial ambitions, and intended to reinforce the structure of permanent colonial rule.

This study analyzes the walking behavior and neighborhood range of the elderly with dementia by comparing them to the general elderly. Gihang-gu, Yongin-si, was chosen as the research site. According to GPS data, the average weekly walking distance for the elderly with dementia was 1.54km, shorter than the 1.79km for the general elderly. Additionally, 41.66% of those with dementia recognized only their immediate surroundings as their neighborhood, a higher percentage than among the general elderly of 27.27%. Their perceived neighborhood area averaged 182,440 m², 16.1% smaller than that of the general elderly, and their actual activity range was 44,284 m², about 20.2% smaller. In conclusion, it can be confirmed that the elderly with dementia tend to recognize their living area centered on the main building and complex where they live more than the general elderly. In addition, it can be inferred that the actual activity range of the elderly with dementia is narrower than that of the general elderly due to the anxiety that they might get lost. To create a dementia-friendly environment, urban design alternatives should reflect the neighborhood range and walking behavior of elderly individuals with dementia.

Street space is the boundary that divides public space and private space, and is the area where the coexistence of the two occurs most actively. Outdoor commercial activities are a case where public and private values coexist, and are commercial activities in the external public area by individuals. Outdoor commercial activities are preferred by many consumers and are actively appearing, but they are also having negative effects, such as the occurrence of civil complaints. The purpose of this study is to break away from the dichotomous concept of public and private space and study the environment of outdoor commercial spaces with the attitude that the urban environment becomes more diverse when the two values coexist. To this end, the characteristics of locations where outdoor commercial activities occur were identified through field surveys, literature research, and drawings. The study area is Euljiro 3 and 4-ga, an area where outdoor commercial activities actively occur. Based on the researcher's field trip, the Inhyeon-dong 1-ga area, where various types of occupancy activities occur, was selected as the research target. As a result of the analysis, it was possible to analyze the characteristics of the point where outdoor business activities occur by dividing them into the characteristics of the street system and the manage of the store. The reasons why outdoor commercial were able to function can be divided into physical environmental and psychological factors. The experience of occupying outdoor space for reasons other than outdoor commerce influences the business operator's decision to occupy outdoor space. Additionally, outdoor commercial activities occurred when goods occupying outdoor space could be stored outside. Outdoor commercial activity is influenced by the physical environment of the street it occupies. Occupancy is influenced by the type of transportation primarily used on the street, the type of business of nearby businesses, and the amenities on the street. This physical environment creates a transition space between the store and the street, allowing it to occupy part of the street. Lastly, outdoor commercial space expands or contracts over time, and its scope varies depending on the user.

Single-person households are becoming more diverse and are steadily increasing in number, not only in the Seoul metropolitan area and large cities but also in small and medium-sized cities across regional areas. However, existing research has primarily focused on Seoul and large cities, with limited studies on smaller cities. This study seeks to identify and categorize areas with high concentrations of single-person households in small and medium-sized cities and to analyze the characteristics of each type. This study focuses on 35 small and medium-sized cities in regional areas, using data from 2020. The analysis was based on the census output area (OA). To identify areas with high concentrations of single-person households, the local Moran's I statistic was applied to the single-person household ratio. Factor analysis was then conducted on regional characteristic variables to derive factors and scores, followed by cluster analysis to identify different types of concentrated areas. The analysis identified nine regional characteristic factors, including suburban, elderly and low-density residential, high-quality job opportunities, old and small residential, employment center, non-residential dwelling, low-rise and high-density residential, and downtown factors. The study categorized the concentrated areas into four types: industrial complex areas, downtown areas, general single-person household areas, and areas around universities.

The purpose of this study is to evaluate the homogeneity of concrete based on its microstructure by measuring random scattering waves and calculating a heterogeneity index for analysis. Concrete exposed to high temperatures was used as a factor degrading the internal homogeneity of concrete, and experiments were conducted on both standard concrete and various types of fiber-reinforced concrete to verify the applicability of the process used to quantify heterogeneity. The method used to analyze internal homogeneity involves calculating a heterogeneity index based on the peak amplitude differences of the random scattering waves. The experiment was conducted on test specimens consisting of standard concrete and nine mixes with four types of fibers (Carbon, Jute, Glass, Steel) mixed at 0.5% and 1% respectively. The exposure temperatures were set at 200℃, 500℃, and 800℃ to analyze the changes in homogeneity due to temperature exposure and fiber reinforcement through experimental research. The results indicate that the changes in homogeneity due to fiber reinforcement, as calculated by the algorithm used in this study, were not sensitive, and no clear relationship between homogeneity and strength was observed. While no clear relationship between homogeneity and strength was observed up to 500℃, a significant relationship was noted at 800℃. This suggests that while the algorithm used in this study has difficulty detecting microstructural changes occurring at exposure temperatures up to 500℃, it can detect changes at 800℃.

Wood is a building material with significant environmental and structural benefits. While various countries have developed design standards for connections in high-rise timber buildings using structural glued laminated timber and steel connectors, South Korea has a noticeable gap in research on these connection methods, with no specific regulations in place. This study builds on previous experimental research on Glued-in rod connections, known for their high stiffness and fire resistance, to develop a finite element analysis model. The model was used to analyze factors such as rebar diameter, embedded length, and the angle between the rebar and timber fiber direction. The analysis revealed different pull-out performances and failure modes, and their correlations were examined.

This study evaluates seismic loads on various steel structures, taking into account amplified ground motions due to different soil conditions. Seismic design codes define ground motions that induce inertial forces during earthquakes through the design response acceleration spectrum. The 1985 Mexico earthquake highlighted the significant impact of soft soil amplification on seismic loads, leading to severe damage in midand high-rise buildings and prompting the introduction of site amplification factors. However, the current Korean seismic design code (KDS 17 10 00: 2024) classifies ground without considering dynamic characteristics, resulting in discrepancies between actual and design response spectra. This research analyzes three soil conditions with different dynamic properties, conducting site response analyses to derive surface ground motions. Twelve steel structures of varying shapes (R-shaped, L-shaped, T-shaped) and heights (4, 8, 12, 16 stories) were examined. By comparing seismic loads from amplified ground motions with those from the design spectrum, the study suggests improvements to the seismic design spectrum. The findings indicated that the proposed spectra (PS-1, PS-2, PS-3), which account for dynamic site characteristics, more accurately predict structural responses than the current KDS-S4 spectrum. Seismic base shear varied by up to 55% depending on site conditions. The proposed spectra enhance design efficiency for structures on short-period (Site-1) and intermediate-period (Site-2) sites. For long-period sites (Site-3), the amplification between modes was less pronounced, underscoring the need for comprehensive ground response analyses to ensure safe designs. The study highlights the importance of revising the design response spectrum to reflect diverse ground conditions, improving structural safety and performance predictions.

Government data indicated plans to establish a smart construction technology roadmap to revitalize the construction industry, including a mandate to apply BIM in all public projects by 2030. Consequently, the use of BIM in design, construction, and maintenance is expected to expand gradually across domestic construction sites. As buildings grow larger and more complex with BIM, the range of construction equipment and materials involved has also increased, heightening the risk of safety accidents for workers. To address these concerns, BIM is being introduced for construction site safety control, alongside the strengthening of the Serious Accident Punishment Act to prevent recurring safety incidents. However, challenges arise due to a shortage of specialized personnel. Additionally, the use of different software at each site complicates standardization, highlighting the need for a unified BIM module. In this study, a module was developed using Dynamo, a visual coding programming language, to visualize safety information for major accident-causing objects at BIM construction sites without the need for additional add-ons. To assess whether the module contributes to reducing safety accidents, it was applied at a testbed construction site for verification. This approach allows for the visualization of user-centered hazardous object information, providing a decision-making tool for safety management, even at smaller sites lacking comprehensive BIM safety systems.

Promoting wooden construction can significantly reduce carbon emissions by storing carbon in wood materials and replacing carbon-intensive materials like concrete and steel. However, the domestic wooden construction industry remains small in scale. While various strategies have been suggested to revitalize this sector, they often lack a comprehensive understanding of the construction process and detailed implementation plans. This study examines the construction process through in-depth literature reviews and expert interviews, identifying issues at each stage and proposing measures to strengthen the wooden construction industry. An Importance-Performance Analysis (IPA) based on expert surveys was conducted to evaluate the significance and effectiveness of these measures, leading to the development of short-term and long-term strategies for stimulating wooden construction. In the short term, it is crucial to establish support policies linked to carbon incentives, standardize information and classification systems for materials and wooden components, and quantify the benefits of wooden construction through performance data collection. Long-term strategies focus on achieving cost and productivity competitiveness through mass production systems and the localization of wooden construction materials. These findings aim to identify the barriers to the growth of wooden construction and provide a foundation for effective policy recommendations.

The purpose of this study is to analyze the problems of the current education and training system to derive the necessity of education on personal competency and to efficiently cultivate the competency of competent construction company field engineers. The purpose of this study is to suggest ways to improve education and training to improve personal competency in the future by analyzing important personal competency items and competency levels of construction company field engineers. The conclusions obtained through this study are as follows. 1) Most of the field field engineers of construction companies felt that education and training were necessary to improve their personal competency, and it was found that there were many opinions that the current legal education and training hours were insufficient. 2) It was found that the five core competency items that the field engineers of beginner and intermediate construction companies considered important were understanding, responsibility, driving force, sincerity, and quickness. 3) Currently, the competency level of the individual competency items that the field engineers of beginner and intermediate construction companies consider important were all above average, but in the case of beginner, the competency level in planning, vision presentation, coordination integration ability, leadership, and creativity was relatively insufficient compared to intermediate level. 4) In this study, education and training plans to improve the individual capabilities of field engineers were presented based on the results of the survey, and benchmarking plans through cases of developed countries were presented. This study suggested a schematic direction for improving the individual capabilities of field engineers of construction companies, but has a limitation in that it could not present specific education and training plans. In the future, follow-up studies will be conducted to systematically supplement the above-mentioned contents.

In 2022, the construction industry accounted for nearly half of all fatal accidents across sectors in South Korea. This study aims to develop binary like fatality and injury and multi-class such as fall and struck-by classification models using AutoML to predict the occurrence and types of construction accidents, based on data from the Construction Safety Integrated Management System (CSI) database. The dataset, consisting of 235,665 accident cases from January 2019 to February 2024, includes 54 types of information, with 18 influential accident factors identified. Preprocessed data were trained and tested using AutoML to determine optimal algorithms and influencing factors. Accuracy, precision, recall, and F1 score metrics were used for validation. The binary classification model for predicting fatalities and injuries, developed using the Extra Trees (ET) algorithm, achieved the highest accuracy of 95.9% and an F1 score of 0.2771. For predicting accident types, the multi-class classification model using the LightGBM (LGBM) algorithm recorded the highest accuracy of 57.4% and an F1 score of 0.5503. Feature importance analysis revealed that the accident object was the most critical factor in both models. This research is expected to enhance safety management performance by efficiently identifying the likelihood and types of construction accidents.
