왕뤄한(Wang, Ruo-Han) ; 박수빈(Park, Soo-Been)

https://doi.org/10.5659/JAIK.2024.40.11.3

This study examines differences in students' use of homebase, a common space for the high school credit system, by the type of homebase-the alcove type, the hall type, and the separated-room type. Field surveys and observational surveys were conducted in three high-schools currently operating a high school credit system in Busan. Students' homebase usage behavior was divided into static activity, dynamic activity, and interactive activity and observed during morning and afternoon recess (10 minutes) and lunch time (60 minutes). Results are as follows: (1) School A built an Alcove type homebase, providing separate space for male- and female students at both ends of the corridor. It guaranteed privacy but is far from the curriculum block. Students rarely used homebase during recesses and engaged in both interactive and individual activities during lunch hours. (2) School B built a Hall type homebase in the center of the curriculumblock. A high number of students took part in dynamic activities. Interactive activities mainly took place in public areas centered around the homebase, while static activities took place in quiet areas around the homebase. (3) School C built the Separate-room type homebase adjacent to the subject classrooms. Students mainly participated in learning activities and consulted with teachers. Static and dynamic individual activities took place in private area secured using movable furniture, while interactive activities took place at muti-sitting tables or lounge sofas.

김은희(Kim, Eun-Hee) ; 김꽃송이(Kim, Kot-Song-I)

https://doi.org/10.5659/JAIK.2024.40.11.25

Despite numerous efforts across various sectors to prevent building safety accidents, major incidents such as collapses and fires continue to occur. Additionally, abnormal weather phenomena resulting from global warming, such as torrential rains, strong winds, and typhoons, are further expanding the hazardous environment. In light of this situation, this study aims to establish reasonable safety management measures during the building creation and management phases that align with the specific characteristics and conditions of each building. The development of a building safety management structure called RAST (Risk Assessment and Safety Determining Tool) serves the purpose of facilitating preemptive risk assessments and safety management plans. RAST comprehensively considers various factors that influence building safety, including the building's intended use, its occupants, the surrounding land, roads, and environment. By doing so, it allows for a determination of the potential risk level of the building itself and enables effective responses to the causes of safety accidents, as well as planning for safety-related elements.

창쩌위안(Chang, Ze-Yuan) ; 한정원(Han, Jeong-won)

https://doi.org/10.5659/JAIK.2024.40.11.37

Despite the proven of virtual reality(VR) as an innovative design presentation tool in architecture and interior design, research on users' perceived usability of virtual environments remains limited. This study developed an immersive virtual reality interactive environment (IVRIE) capable of real-time interaction and movement. An experiment involving 46 students majoring in spatial design was conducted, revealing that IVRIE provides users with a stronger sense of immersion compared to traditional static VRs. It enhances design evaluation during both the scheme presentation and decision-making stages. Using the Technology Acceptance Model TAM) framework, the study found that perceived value(PV) and positive attitude(PA) significantly influence the intention to use(IU). IVRIE improves spatial experience, user interaction with design spaces, and understanding of spatial information. Participants preferred IVRIE over traditional methods, highlighting its efficiency and potential for future design presentations.

Tax Comparison Analysis for Individuals vs. Corporations in Real Estate Purchase and Sale

권준범(Kwun, Joon-Beom) ; 김덕수(Kim, Duksu)

https://doi.org/10.5659/JAIK.2024.40.11.49

The purpose of this study is to empirically compare and analyze the differences between individuals and corporations in real estate transactions and to investigate whether the strong policies applied to corporations when acquiring real estate are actually effective. To achieve this issue this study examined the tax rates applied to individuals and corporations and investigated the practical differences when buying and selling a home at the same condition. As a result this study found that the different policies and tax rates applied to corporations have a significant potential for misuse in real estate buying and selling which is contrary to expectations. As demonstrated in this study's simulation of housing transactions by individuals and corporations, hasty policies are not only likely to be misused as tools for realizing short-term capital gains, but also may unnecessarily distort the real estate market by making long-term ownership more difficult. This simulation study on the correlation between real estate policies and property prices confirms this and hopes to serve as a foundation for future research that can contribute to the stabilization of real estate prices.

이수연(Lee, Su-Yeon) ; 최춘웅(Choi, Choon)

https://doi.org/10.5659/JAIK.2024.40.11.77

This study examines the evolution of curtain wall details in Kimm Jong Soung's architecture, focusing on high-rise buildings from the 1970s to the 1990s. It emphasizes the profound influence of Mies van der Rohe’s design principles on Kimm’s work, focusing on the similarities between Kimm’s curtain wall details and those of Mies. Initially, Kimm followed Mies’s formal principles, but he later reinterpreted and developed these details to fit Korea’s industrial and architectural context, establishing his own curtain wall design philosophy. The study explores how Kimm overcame the technological and industrial limitations of Korea at the time to apply these design principles. Despite restricted materials and construction technologies, Kimm creatively reinterpreted Mies’s ideas through meticulous attention to curtain wall details. His curtain wall designs go beyond simple facade treatments, serving as visual records of the evolution of Korean architecture. This re-evaluation of Kimm’s approach to curtain walls holds significant meaning in Korean architectural history, as it highlights his achievement in integrating structural and aesthetic elements.

https://doi.org/10.5659/JAIK.2024.40.11.89

This study analyzed the key elements that changed during the redevelopment process for 131 district unit planning zones in Seoul, selected from the 467 total plans established by the end of 2022, in order to identify specific characteristics and trends by type. The district unit plans were classified into three main categories, and the analysis focused on how redevelopment occurred differently in each category. Among the three types, the "Planning Management" type experienced the most frequent redevelopments, with an average cycle of 110.9 months between redevelopments. The "Planning Management" and "Development and Improvement" types commonly showed significant changes in land use, building density, and floor area ratios. On the other hand, the "Conservation and Regeneration" type had more noticeable modifications in terms of building form, architectural style, and appearance. These findings suggest the need for a more tailored approach to redevelopment processes and underscore the importance of continuous monitoring of frequently altered elements in district unit plans, ensuring long-term effectiveness and adaptability to urban changes.

https://doi.org/10.5659/JAIK.2024.40.11.101

Modern architecture is realized through the collaboration of experts from various fields such as design, construction, structure, and facilities. However, in the design and construction process of Hanok so far, the opinions of the constructors have mainly been accepted, leading to various communication issues. This study identifies that the cause of these issues arises from the numerous types and complex names of Hanok components. In this context, communication in architecture is carried out through drawings, making it essential for everyone involved in the construction to understand standardized drawings. However, in the traditional Hanok construction process, effective communication through drawings has been difficult due to the differing levels of background knowledge among participants, resulting in construction being led by one party with relatively higher background knowledge. Therefore, by standardizing and simplifying the method of marking components in the Hanok drawing process, this study aims to improve Hanok drawings to enhance communication, reduce construction errors, and streamline the overall construction process.
