This study examines the concept and characteristics of immersive theatres through previous studies. Immersive Theatres can be understood as a form of performance that breaks the boundaries between the stage and the auditorium in various spaces so that the audience can actively participate in the performance or immerse themselves sensibly. However, since it absorbs various art forms and continues to change and develop, it is important to recognize the concept by grasping its characteristics as an immersive experience rather than defining it as one. Based on the theoretical background of the concept and characteristics of the theatrical producers and immersive theatres, the producing immersive theatre < The Great Gatsby> is analyzed to derive differences between the immersive theatre and the general performances. In conclusion, it is important to recognize that immersive theatres have audiences at the center of all aesthetic performance environments. The role and position of the audience as a "passive consumer" change to an "active and creative consumer" in immersive theatres where the audience-centered immersive environment and experience are the key, and it was found that not only producers but also the creatives should change their perception of the audience and reflect it in the producing.

This study is based on social needs for green healing spaces assumed to enhance mental health in a city. This study proposes development directions through the analysis of modern social recognition factors for neighborhood gardens. As a research method, web information data was collected using Textom among big data tools. Text Mining was conducted to extract elements and analyze their relationship through keyword analysis, network analysis, and cluster analysis. As a result, first, the healing space and the healing environment were creating an eco-friendly healthy environment in a space close to the neighborhood within the city. Second, neighborhood gardens included projects and activities that involved government, local administration, and citizens by linking facilities as well as living culture and urban environments. These gardens have been reinforced through green welfare and service programs. In conclusion, friendly gardens in the neighborhood for the purpose of public interest, which are beneficial to mental health, are green infrastructures as a healing environment that can produce positive effects.

This study was conducted to provide implications so that teachers' voices are heard in the social consensus for future schools by exploring teachers' needs for future school spaces. A qualitative study was performed to listen to teachers' voices directly, and 10 teachers from "A" Elementary School (tentative name) participated in the study. The study 1) recognized the emergence of learning that transcends time and space, and emphasized the importance of an ICT-based informatization environment that can support such learning, 2) confirmed the characteristics of futuristic school spaces centered on "tradition" and "technology," 3) recognized the importance of learning community spaces, 4) emphasized "variable" classrooms for flexible teaching and learning activities, and 5) confirmed the need to introduce eco-friendly elements and provide support for those who may be vulnerable in high-tech learning environments. Finally, the study concluded that teachers need systematic education and experiences that contain sufficient important discourses related to future schools such as "eco-friendliness" and "connection with local communities".

The study area is located in Hyeonseo-myeon and Andeok-myeon of Cheongsong-gun, Korea around the Yeongcheon dam waterway tunnel, and in this paper, it is analyzed whether the groundwater level is recovered or not compared to groundwater level before waterway tunnel construction by measuring the groundwater level of 156 wells which were installed in areas near and away from the waterway tunnel. From September 2017 to August 2018, the groundwater level of the well was measured at least once a month, and as a result of groundwater level observation survey, the groundwater level of wells distributed in the directly affected zone by the waterway tunnel is relatively lower than that of the indirectly affected zone apart from the waterway tunnel. These results are estimated to be predominantly affected by the effect of waterway tunnel acting on geologic discontinuities rather than by terrain conditions, i.e. groundwater flows being leaked to the waterway tunnel through direct or indirect channels. Continuous monitoring and further investigation will be required to maintain groundwater facilities and preserve groundwater environments in the future.

This paper proposed an environmental standard far beneficial use of dredged materials currently considered as waste materials. In Korea, even though chemical analysis of sediments are carried out frequently, their analysis results were not interrelated with the effects of biological lives due to a shortage of data, which may result in difficulty to develope Korean standards for reusing dredged materials. For these, this paper first searched existing foreign standards, analyzed local contaminated sediment data, identified their main components of contaminations and then compared clean-up standards of sediments consisting of lower and higher level. From these analyses new environmental standards considering Korean domestic circumstances are proposed. It is judged that newly proposed standards are appropriate in terms of both Korean national sedimental environments and economical recycling aspects because environmental standard levels proposed are higher than background level of sediments in Korea and foreign country's standards, where many experiences and environmental monitoring works have been already performed.

Minor mergers leave behind long lived, but extremely faint and extended tidal features including tails, streams, loops and plumes. These act as a fossil record for the host galaxy's past interactions, allowing us to infer recent accretion histories and place constraints on the properties and nature of a galaxy's dark matter halo. However, shallow imaging or small homogeneous samples of past surveys have resulted in weak observational constraints on the role of galaxy mergers and interactions in galaxy assembly. The Rubin Observatory, which is optimised to deliver fast, wide field-of-view imaging, will enable deep and unbiased observations over the 18,000 square degrees of the Legacy Survey of Space and Time (LSST), resulting in samples of potentially of millions of objects undergoing tidal interactions. Using realistic mock images produced with state-of-the-art cosmological simulations we perform a comprehensive theoretical investigation of the extended diffuse light around galaxies and galaxy groups down to low stellar mass densities. We consider the nature, frequency and visibility of tidal features and debris across a range of environments and stellar masses as well as their reliability as an indicator of galaxy accretion histories. We consider how observational biases such as projection effects, the point-spread-function and survey depth may effect the proper characterisation and measurement of tidal features, finding that LSST will be capable of recovering much of the flux found in the outskirts of L* galaxies at redshifts beyond local volume. In our simulated sample, tidal features are ubiquitous In L* galaxies and remain common even at significantly lower masses (M*>10^10 Msun). The fraction of stellar mass found in tidal features increases towards higher masses, rising to 5-10% for the most massive objects in our sample (M*~10^11.5 Msun). Such objects frequently exhibit many distinct tidal features often with complex morphologies, becoming increasingly numerous with increased depth. The interpretation and characterisation of such features can vary significantly with orientation and imaging depth. Our findings demonstrate the importance of accounting for the biases that arise from projection effects and surface-brightness limits and suggest that, even after the LSST is complete, much of the discovery space in low surface-brightness Universe will remain to be explored.

The advent of the 4th Industrial Revolution due to the trigger of digital technologies such as artificial intelligence and big data has caused many changes in society, culture, and industry. However, traditional markets in each region are not responding quickly to new distribution environments and consumer changes. In particular, in the case of traditional markets in Jeju, regional characteristics such as marketing strategies for tourists visiting Jeju have not been utilized. Therefore, this study proposes the establishment of a smart traditional market based on big data and artificial intelligence that utilizes the regional characteristics of Jeju. The research contents include customer profiling through visitor big data analysis, providing tourist movement results through traffic analysis, providing real-time popular product charts, and developing video-based fire and crime prevention functions.

Urban trees play an important role in absorbing carbon dioxide from the atmosphere, improving air quality, mitigating the urban heat island effect, and providing ecosystem services. To effectively manage and conserve urban trees, accurate spatial information on their location, condition, species, and population is needed. In this study, we propose an algorithm that uses a high-resolution urban tree cover map constructed from deep learning approach to separate trees from the urban land surface and accurately detect tree locations through local maximum filtering. Instead of using a uniform filter size, we improved the tree detection performance by selecting the appropriate filter size according to the tree height in consideration of various urban growth environments. The research output, the location and height of individual trees in human settlement over Suwon, will serve as a basis for sustainable management of urban ecosystems and carbon reduction measures.

A data set of current, wind and wave height measured at the monitoring buoy and sea level at Busan harbor were analyzed to explain the physical conditions during the strong rip current events at Haeundae Beach of Suyeong Bay during 13~15 August 2009. Tidal current, with spring-neap variations, has similar average speed to the short-term non-tidal currents. The common features at the time of rip currents are the strong northeasterly wind and superposition of tidal and non-tidal currents both flowing toward the coast. However on 14 August when the rip current did not occur, tide and wave height were similar to the rip-current cases but the tidal and non-tidal current were to nearly opposite directions. While strong winds produce large waves thus the basic condition for rip current but its influence on the local circulation in the bay is relatively small. Of the three adjacent beaches, only at Haeundae the rip currents are reported. This difference may be due to the unique bottom topography featured by underwater hill in the central region off Haeundae which can decay the incoming waves, tides and currents to intensify the rip current.

Housing is an essential element of human living environments. The type of housing occupancy can vary based on age, family composition, occupation, education level, and economic situation. In this study, we used social survey statistics to investigate the relationship between housing ownership types and individual and societal characteristics. The research findings revealed that apartment residency rates were high across all age groups. Married individuals tended to have higher apartment residency rates compared to unmarried individuals. Additionally, as the number of household members and generations increased, so did the likelihood of apartment residency. Overall, higher income levels and stable employment were associated with a preference for homeownership. However, there was no significant correlation between homeownership and education level or employment status. National and local authorities should focus on housing supply that aligns with the purchasing capacity and characteristics of potential homebuyers.
