In this study, we will analyze the classroom space of elementary schools that have implemented the Seoul Metropolitan Government's 'Dream Classroom' project and identify satisfaction and needs in terms of users. Primary school was selected and the composition and color of space was investigated by the present ministerial inspection. The survey was conducted on homeroom teachers and analyzed as SPSS/WIN Statistical Programme 22.0. The satisfaction level of space elements was verified by the technical statistical analysis, the general classroom and the 'classroom with dreams' difference in response t-test, the need for planning elements (criticality), and the difference in satisfaction with one way ANOVA. The space had the most separate, primary-colored classrooms. They preferred emotional factors and bright and light atmosphere for the lower grades, and the soft and soft atmosphere for the middle and high school students. The school preferred communication space with the community, proper play and relaxation space for the complex type of classroom. This will help set the direction for elementary school classroom space planning during the Fourth Industrial Revolution.

Recently, the roof garden of the large commercial facilities has been changed as a complex cultural space follow the users' diverse needs. It is focused on large commercial facilities on Seoul and Gyeonggi area but large commercial facilities of the province still has not been able to respond to the needs of users. Thus, the present condition of roof gardens was compared space components with physical environmental factors in Seoul, Gyeonggi and Daejeon, Chungcheong. Throughout the comparison, roof gardens in Daejeon and Chungcheong area were focused on finding ways to improve As a result, roof gardens in Seoul and Gyeonggi area were applied to a variety of factors in space components experience, learning, performance, exhibition and etc. It is composed to take place of various acts in the roof garden. On the other hand, roof gardens in Daejeon and Chungcheong were not applied a variety space components by comparing Seoul and Gyeonggi area. Physical environmental factors also were insufficient by comparing Seoul and Gyeonggi area the landscape, awning facilities, amenities for handicapped. As described above, space components and physical environmental factors in Daejeon and Chungcheong area roof gardens were insufficient. To perform the role of the roof garden changing as a complex cultural space and to confront to the users' needs space component such as learning, performance, exhibition should be considered during planning. And physical environmental factors supportable space components should be considered together.

The film has always reflected the culture of the era based on reality and imagination. The visual effect in the film has mainly played a role of expressing the reality more realistically or recognizing the virtual as reality. This study examines the meaning and the effect of fantasy realism through Oasis of Lee Chang-dong. Fantastic realism has separated the reality from the imaginary space by using a dual meaning tool that affects the time and space in the film and reflects the human desire and desire to see. It was also reproduced in the real world through the medium of pigeons. In addition, it separates visualized space from non-visualized space in film narrative structure, separation of real and unreal space, segregation of consciousness and unconscious space, and separation of reality and reality space into power structure. With the development of technology, the image of the yellow image comes closer to us like reality, which will express the space of unconsciousness that we could not think of.
