The 'one-day-shopping' concept that we experience today in a modern mega mall changed the propensity to consume compared to the past. The idea of a mega mall originated in the U.S. and the first suburban shopping malls as we know them today were built in the 1950s. The convenience of these malls had a great impact not only on consumers but also on the retail industry in general and the new mega mall idea has since spread around the world, with the largest ones located in China and Southeast Asia. Meanwhile, Korea had the fastest-growing economy during the last three decades and with that boom the compositional structure of domestic retail facilities became extremely diverse. Today, there are 36 new mega mall development plans to be completed before 2016, which represent a rapid and dynamic change in consumerism lifestyle in Korea. In this regard, this study will re-evaluate the first mega mall in Korea, the COEX Mall, and identify initial errors regarding its circulation plan and provide an ideal design strategy for future commercial mega malls based on literature review and comparison analysis.

The main aim of the paper is to reveal what is the sign in art and architecture and what is difference between technology and art. By keeping in mind the suggestions of Heidegger's four different worlds, we become able to discern or elaborate on four different contexts of signs and modes in which the sign can work. World (1) is not conceptualized by selected relations of some of things' aspects with one another; rather, it is constructed by our sensory impressions. The sign of World (1) simply points to other objects occurring in the situation. World (2) emerges as an ontological term, and signifies, in terms of relations that are now brought systematically forth, the Being of those entities of World (1) which we naively perceive or take for granted. The sign of World (2) signifies a constructed world. World (3) is understood as the 'wherein' or environment of beings whose total activity is proven to be inseparable from their circumstances. The sign of World (3) is to recover the perspicuous silence of World (3). The World (4) is the ontological-existential understanding of worldhood. The sign of World (4) is to reveal the conspicuous silence of World (4). Finally, the paper suggests that art including architecture cannot be the sign of World (1), (2) but the one of World (3).

By virtue of recent economic development and cultural progress, the desires willing to enjoy a plentiful leisure life among people are on enlarging, then according to this, the demand for a grand performance hall where various cultural events are achievable is also on increasing. However, since the grand performance hall has its characteristics that must accommodate various forms of performances likely from lecture, meeting activity to recital, and because the clearness of sound is on emphasizing, and also it requires the repletion or abundance of sound simultaneously, it could be said that from the designing stage, a sufficient examination and plan with regard to the architectural acoustics design is indispensable. On such view point, for the object of the grand performance hall under actually planning to build, this Study is attempting to compare analyze on Room Acoustics Characteristics using computer simulation from the stage of design. It is considered that the material analyzed in such way could be reflected in maximum basis to the design of the performance hall that minimizes the acoustic defect at the designing step, and also it could be utilized as the useful material at the time of design for a similar form of performance hall in the future.

The application of microorganisms in the field of construction material is rapidly increasing worldwide; however, almost all studies that were investigated were bacterial sources with mineral-producing activity and not with organic substances. The difference in the efficiency of using bacteria as an organic agent is that it could improve the durability of cement material. This study aimed to assess the use of biofilm-forming microorganisms as binding agents to increase the compressive strength of cement-sand material. We isolated 13 alkaliphilic biofilmforming bacteria (ABB) from a cement tetrapod block in the West Sea, Korea. Using 16S RNA sequence analysis, the ABB were partially identified as Bacillus algicola KNUC501 and Exiguobacterium marinum KNUC513. KNUC513 was selected for further study following analysis of pH and biofilm formation. Cement-sand mortar cubes containing KNUC513 exhibited greater compressive strength than mineral-forming bacteria (Sporosarcina pasteurii and Arthrobacter crystallopoietes KNUC403). To determine the biofilm effect, Dnase I was used to suppress the biofilm formation of KNUC513. Field emission scanning electron microscopy image revealed the direct involvement of organic-inorganic substance in cement-sand mortar.

As buildings have become higher and larger, the use of high performance concrete has increased. With this increase, interest in and use of ultra fine powder admixture is also on the rise. The silica fume and BSF are the admixtures currently being used in Korea. However, silica fume is exclusively import dependent because it is not produced in Korea. In the case of BFS, it greatly improves concrete fluidity and long-term strength. But a problem exists in securing early strength. Furthermore, air-cooled slag is being discarded, buried in landfills, or used as road bed materials because of its low activation energy. Therefore, we investigated in this study the usability of nano-slag (both rapidly-chilled and air-cooled) as an alternative material to the silica fume. We conducted a physic-chemical analysis for the nano-slag powder and performed a mortar test to propose quality standards. The analysis and testing were done to find out the industrial usefulness of the BFS that has been grinded to the nano-level.

Aalto designed his own modern architecture in comparison with other modern architects of his days. It is because Aalto went beyond the principle of dogmatic functionalism based on his attitude not to copy images of functionalism but to fulfill function of the building. He decided architectural form and space according to logical basis including the effective use of light and sound. Vuoksenniska church, as is called the most exceptional and notable church in his works, was designed based on the fulfillment of program. As he knew that the program needed the extension of the main church space into social areas, he put emphasis on individuality of space rather than the wholeness of space. Sound and light analysis of Vuoksenniska church shows that Aalto tried to have adequate environment of each space at the start and Integrate them later. The spatial configuration of Vuoksenniska church shows that the individuality of space has priority over the wholeness of spaces. Discordance between roof form and ceiling is the best example for this matter. Aalto designed various windows that have different sizes, figure and location to induce desirable light for each space of the church. He also adjusted the shape of the ceiling and the angle of wall for a effective sound transmission. This result indicates that he knew the activity of the church is normally confined to one weekly morning and the whole space Is hardly used as a religious purpose.

The most ordinary form of residential type in Korea is a plate-type apartment, and the common space in these apartment is attracting as an important factor for enhancing social exchanges among neighbors and forming community consciousness. In addition, it provides a sense of psychological security by enabling natural exchanges and communication in contemporary society. It is desirable to plan the flow of space in such a way that private, semi-private, semi-public, and public spaces are linked. Semi-private and semi-public spaces can be defined as common spaces. Semi-private spaces are strongly recognized in the order of unit household entrance, main entrance, elevator, corridor, staircase, playground, bench, trail, walkway and parking lot, exercise space, main/back gate, the ability to gratify is increased sense of belonging, ownership consciousness formation, defensive function. Semi-public space is strongly recognized in the order of playground, bench, exercise space, trail, main entrance, walkway and parking lot, unit household entrance, main/back gate, corridor, staircase, elevator, the ability to gratify is increase of social contact, Secondary activity space function. In addition, the function to gratify in the common space differs according to gender and age group among resident characteristics, and differs according to corridor type, parking lot type and main entrance type. Therefore, differentiated planning of common space is needed in consideration of these differences in the design of common space in future.

The purpose of this study was to analyze the perception among participants in the Built Environment Education(BEE) programs for children. And also, hopefully, we would get some strategies for development of BEE program through post-evaluation. The survey was conducted by the students and the parents who were participated in the four BEE programs. The key results are as follows: 1) The way of participation in the programs was limited. We should consider public relation strategies and its sustainable curriculum. 2) The students felt easy to learn from the lecture, but we need to consider the students' ability in craft activities and the level of school grades. 3) Most of the participants was satisfied with the programs. For students, the 'Educational Environment(Hours & Facilities)' was highly correlated with overall satisfaction. On the other hand, in the case of parents, the 'Teacher' was highly correlated with overall satisfaction. 4) Parents were aware of the need to link the BEE program to school education such as a subject of 'Creative Activity.' The BEE as an integrated program would be a school curriculum or contents of STEAM education. At the end of this paper, the meaning of this study was discussed.

The purpose of this study is to present the direction of the new space plan by reflecting the opinions of the user (student) in the existing standardized elementary school space planning. The purpose of this study is to investigate the activities of elementary school students by using socio - spatial network analysis method and to propose the direction of new elementary school space planning through the results. We analyzed the results of each centrality by using the analysis of closeness analysis, betweeness analysis, girvan-newman clustering, and concor analysis. The results of this study are as follows. First, it should be planned to use the classroom and the special room as one area by utilizing the corridor. Second, it should be planned that the outdoor space and the indoor space are closely related to each other by utilizing the hall, the lobby and the classroom. Third, the school should create a small space where physical activity is possible in an indoor space of the school. In order to improve the standardized elementary school space, this study proposes a method to reflect the opinions of the users in the school planning stage.
