This study aims to investigate the key attributes of a steadily growing hotel sector (lifestyle hotels), which has shown great success in the global competitive market, by analyzing user-created content on Instagram. The dataset used in this study were prepared from a total of 20,999 lifestyle hotel posts and 24,262 boutique hotel posts created from 2013 to 2020 and retrieved using a Python web crawler. The locations, hashtags, and image data were analyzed based on frequency analysis using social network analysis methods and computer vision technology, after which they were visualized with a geographical information system and Gephi. The results demonstrated that lifestyle hotels share key attributes that differentiate them from others in terms of physical, geospatial, and experiential contexts. Design, location, and management type are the main attributes that comprise the distinct identity of each lifestyle hotel. Moreover, a lifestyle hotel is distinct from a boutique hotel in that staying in the former means consuming experiences with continuous changes. The information and knowledge gained from this research will contribute to bridging the gap between theoretical literature and the practical development of lifestyle hospitality.

This study aims to explore the effective types of signage in augmented reality (AR) environments. Although AR, a state-of-the-art technology, has been utilized in diverse contexts, its application in real-world situations is limited. This study examines the effectiveness of AR signage in mixed-use shopping malls in terms of wayfinding, which is a continuous problem. First, the time it took to make a decision was measured for three categories of signage: existing signage, AR-textual signage, and AR-graphic signage. Thirty directional sign images from the three categories of signage were used in the experiment. The sign images of the current sign system at the mixed-use mall were used as the control condition. Second, subjects were asked in a questionnaire to evaluate each AR-enhanced sign type in 5 aspects: uniformity, continuity, legibility, clarity, and aesthetics. The result found that AR-graphic signage is the most effective type in terms of decision-making time and aesthetics. However, it was found that for legibility and clarity of signage, textual elements should be adjusted in AR signage environments. Thus, this research suggests the use of mixed graphic and textual signage in AR environments.

With increasing demands on medical care services, one of the trends is the mixed patient room arrangement of single/double-bed and multi-bed rooms in a nursing unit on the same floor. This influences nurse-to-patient assignment and often causes an unbalanced workload and longer travel distances for nurses. The objective of this study was to investigate how floor configuration and room density influence nurse travel in the hospital's medical surgical units in Korea. This study presented a novel approach to measure nurse travel distances in eight existing nursing units. The agent-based simulation was conducted to model nurses' walking trails, and the distance of one nurse travel to assigned patient rooms was measured for each nurse. With revisions in the spatial arrangement of patient rooms, locating multi-bed rooms near the nurse station, symmetric room layout centering the nurse station, and planning both single/double-bed and multi-bed rooms on one side of corridors, nurse travel distance decreased more than 15%. This study contributed to the knowledge of agent-based simulation as an evaluation framework for spatial analysis. Apart from application to Korea, these results are particularly of interest in countries where private patient rooms are not commonly economically feasible.

This study quantitatively evaluated subjects’ visual perceptions and experiences of an architectural environment in virtual reality. This study was conducted to empirically determine which spatial elements subjects were most interested in in virtual architectural space; to analyze the sequence of objects that captured subjects’ visual attention, how long each object captured their attention for, and the number of objects in each area of interest that captured their attention; to analyze subjects’ emotional responses to virtual architectural spaces. A head-mounted display with an integrated eye-tracking device was used to measure the visual attention that subjects paid to spatial elements of a virtual environment. The result showed which architectural and interior elements subjects paid the most attention to in an area of interest in the virtual architectural space. This study’s findings provide useful information and practical guidelines to architects and designers about which built environment elements attract occupants’ visual attention and what types of physiological responses the elements cause. The conclusions drawn from evaluating visual perception with state-of-the-art VR integrated eye-tracking technology can inform architectural design processes to improve user experiences.

The elderly suffer from discomfort in social life owing to the decline of their physical, psychological, and social functions. The elderly who spend a lot of time indoors require an intelligent system to extend their time to live independently in a residential environment. Recently, the Ambient Assisted Living (AAL) concept was introduced to commercialize various technologies and apply them to urban and architectural environments. However, AAL’s connection to architectural elements is insufficient. This study intends to build a residential environment platform that integrates Internet of Things (IoT) technology and architectural elements to support the independence of the elderly based on the AAL concept. The proposed platform is designed to be applied to various scenarios and services. A responsive façade system was designed to verify the platform, and the usefulness of the system was evaluated through the interaction of the designed façade and an acting manager.

As the concept of prospect-refuge defines a preferred environment, the spatial elements that provide good conditions for the catalyst of the theory have been extensively studied. The well-known architectural element of this theory is the window that optimizes visual openness to outdoor or enclosure from outdoor. The aim of this paper is to develop a design method for prospect-refuge condition by adjusting window design attributes. A parametric design model that measures spatial conditions and presents design alternatives for the window is proposed in two major phases. First, this paper explains a parametric model to generate design alternatives for a window according to its size, aspect ratio, location, and shape. In the second phase, the parametric algorithm is defined for the measurement of prospect-refuge with 3D visibility. As a result, we explore the impact of window design variables on average visibility and difference visibility of prospect and refuge area. Using the parametric design technology, the proposed method presents analytical techniques, considering spatial characteristics.

This paper presents a method that combines visibility graph and isovist analyses to investigate the spatial and social properties of architectural plans for aged care facilities. The potential of the combined method is examined by measuring the properties of three sets of plans for residential aged care facilities. The first set is a pair of hypothetical, idealized plans, which allegedly reflect the “best practice” in the industry. The second set comprises a pair of plans for recent Australian designs, and the third set is a pair of plans for South Korean facilities. Results of the computational analysis of these six plans suggest that social and cultural factors may shape the design of aged care settings and partially explain their international differences. The application of this methodological approach contributes to the understanding of the relationship between spaces and their cultural and social properties in the design of aged care facilities

Collective housing in South Korea started its introduction from the early 1960s, and became the most important residential type in 50 years. Because of the importance of collective housing in many countries and in South Korea, many studies on collective housing have been conducted. Although these studies can provide criteria and methods quantitatively and objectively, classification of types is dependent on researcher’s judgment, and classification of type without considering the plan’s time of creation has a limitation to derive changes in type patterns. The purpose of this study is to analyze changes quantitatively and objectively in patterns of spatial structure and to derive types of spatial structure of collective housing in South Korea algorithmically using a time-based joining method that produced a phylogenetic tree using similarities of spatial structure and plan creation time. This study also supports a research frame for researchers who want the use of a time-based joining method. The study analyzed the relationships of changes in spatial structures of 890 collective housing unit plans in Seoul, South Korea, constructed from 1970 to 2015.

Residential ubiquitous computing environments have focused on interconnecting environmental controls using a home network and the management of sensor data rather than a context-aware inference. Building upon previous research, this paper proposes a novel sensor-based context-aware system with a focus on three inference processes: rule, inference and pattern driven. Using pattern data derived from five families for a working week and establishing rules and inferences, the proposed context-aware system is demonstrated using electrical lighting as an example. The processes to develop an intelligent house are described so as to ameliorate personalized services in response to inhabitants’ needs.
