  • Accurate indoor localization of construction workers and mobile assets is essential in safety management. Existing positioning methods based on GPS, wireless, vision, or sensor based RTLS are erroneous or expensive in large-scale indoor environments. Tightly coupled sensor fusion mitigates these limitations. This research paper proposes a state-of-the-art positioning methodology, addressing the existing limitations, by integrating Stereo Visual Inertial Odometry (SVIO) with fiducial landmarks called AprilTags. SVIO determines the relative position of the moving assets or workers from the initial starting point. This relative position is transformed to an absolute position when AprilTag placed at various entry points is decoded. The proposed solution is tested on the NVIDIA ISAAC SIM virtual environment, where the trajectory of the indoor moving forklift is estimated. The results show accurate localization of the moving asset within any indoor or underground environment. The system can be utilized in various use cases to increase productivity and improve safety at construction sites, contributing towards 1) indoor monitoring of man machinery coactivity for collision avoidance and 2) precise real-time knowledge of who is doing what and where.

  • This study investigated the architectural expression of Taekpungdang(澤風堂, The Pond and Wind House) built by the Neo-Confucianist Taekdang Lee Sik(澤堂 李植, 1584~1647) from the perspective of the symbolic system of the Zhōuyì(『周易』, Classic of Changes). This study examined the historical context, personal history, and construction process of Taekpungdang at the time of its creation through his collection of writings, the Taekdanggip(澤堂集). The study also estimated the original form of Taekpungdang through field surveys and historical evidence. In addition, the architectural principles and architectural expressions inherent in the Taekpungdang were derived based on the symbolic system of "taekpungdaegwa"(澤風大過) which is Lee Sik's divination and one of the 64 trigrams in the Zhōuyì. Lee Sik, who was knowledgeable in the Zhōuyì, used divination to cope with the chaotic political situation and his own misfortunes. Accordingly, He determined the direction of his life and planned the surrounding environment, architectural structure, and form of Taekpungdang based on the rules and meanings of his divination system. He embodied the architectural space of Taekpungdang with the concept of time and space inherent in the divination of "daegwa",(大過, great exceeding). In addition, he expressed the principle of the generation of palgue,(八卦, the eight trigrams for divination) and the principle of the co-prosperity of ohaeng(五行, the five elements) through the composition of walls and windows of the house. The images of Taekpungdaegwae, which are dongyo(棟撓 wood submerged in the pond) and taekmyeolmok(澤滅木, shaking pillars), were manifested in the form of buildings. Therefore, Taekpungdang can be considered a remarkable example of a building designed through the thorough utilization of the Zhōuyì divination system.

  • Architectual environment in this study means a language and meaning complex which makes communication between human beings and environment possible. The purpose of this study is to propose a semiotic approach to analyze and examine meaning, as a semiotic system, and its effects, focusing on the generative meaning in the relationship between human beings and environment. For this purpose, it examines the academic status of modern semiotics in postmodernism and the possibility of its being metalanguatge for a study of a variety of cultural phenomena and desigv. It also provides two viewpoints as propositions for its analysis: it explains the necessity of environmental-discoursive attitude and social-semiotic viewpoint which understands environment as social-cultural reflectors. Finally, it provides framework and all the interpretative procedures for analysis of environmental meanings on the basis of the approach of semiotics of space. By applying the methods proposed this study to the case studies, it also proves validity of this approach and the potentialities of the application of semiotics. This study emphasizes not only denotative configuration of the architectural environment but also its connotative meanings. It maintains that designers, architects, and theorists should realize correctly today's changed value system and social and aesthetic paradigms. It also stresses the necessity of development of the new architectural language and meaning system.

  • This paper provides a social knowledge for pragmatic application guidelines of the interior finish materials within apartment houses, based on both the awareness of practitioners and as it applies to the realities. For this purpose, a series of the questionnaires survey on the awareness of interior finish materials in recently-constructed and remodeled apartment houses was performed, which has extended its probe into the awareness of architectural practitioners. The questionnaires asked practitioners how much they desire sustainable finish materials and the difference in various parties were analyzed and compared, formulating the pragmatic solution in the determination of interior finishes. Comparative analysis of the awareness of construction specialists, interior designer, architectural environmental researchers on environment-friendly finish materials showed that all parties were right to recognize the significance of sustainability in interior finishes. Practitioners believed that occupants must bear the additional expense for the environment-friendly finish products. Also, the results tell that the amount used of environment-friendly products increases as expertise on sustainability in interior finishes rises.

  • This study aims to examine factor of tourism attraction and tourism satisfaction in order to product plan of tourism policies related to architecture and urban design focused on Marado, Jeju Island. For that, a questionnaire is conducted by tourists who visit to Marado. The results are as follows. 30s and 40s tourists evaluate that Marado is more attractive in natural environment rather than 60s. Tourists who visit more than four times to Marado evaluated low in satisfaction for landscape of Marado but tourists who reside in other area not Jeju evaluate higher in satisfaction for landscape. The difference of residence areas shows same result in tourism attraction factors. Tourists participating in tour activities show higher in satisfaction rather than no-participants but the difference between participants and no-participants is not showed in tourism attraction factors. Tourism attraction is extracted four factors; natural environment, architectural environment, economic efficiency and psychological factor. The factors of natural environment and architectural environment have the relation with satisfaction but the factors of economic efficiency and psychology do not show no relation with satisfaction.

  • Reduction in competence makes older adults with dementia more sensitive to the influence of the physical environment. The aim of the longitudinal study was to examine whether residents with dementia in long-term facilities with variability in physical environmental characteristics in Vancouver (N= 11), Canada and Stockholm (N=13), Sweden had a difference in their quality of life (QoL). QoL was assessed using Dementia Care Mapping tool three times over one year for the reliability of data. The results of the study demonstrated that the residents with dementia living in a homelike and positive stimulating setting showed less withdrawn behaviors and a higher level of well-being compared to those in a large-scale institutional setting. This study also found that the residents living in a large-scale institutional environment spent more monotonous times than the other groups, which may be to provision of fewer structured activity programs or less social interaction with neighbors or staff members. Residents living in a large-scale institutional setting in Canada showed so far as five times more agitated/ distressed behaviors and twice more withdrawal compared to the ones living in a small-scale homelike setting in Sweden. The study supports that the large-scale institutional environment was considerably associated with levels of lower quality of life among the residents with dementia.
