This study is examine the scales applied to buildings in the age of Unified Silla through construction sites excavated and its results are as follows; First, scales used in the age of Unified Silla were varied like Jucheok, Dangcheok and Hancheok, but it was generally accepted that Dangcheok was used in Yeongjocheok Since it was found that the scales applied to Dabotap at the Bulguksa temple and main building of the Gameunsa temple belonged to Goguryeo, Yeongjocheok scale used early in the age of Unified Silla was transitional and it was thought that Goguryeocheok and Dangcheok were used togethar. Second, according to actual rulers in Korea, china and Japan, the length of Dangcheok(ruler used in Chinese Tang era) mostly belonged to the extent of $29.25cm\;{\sim}\;30.5cm$(central value: 29,71cm). Third, plane features of main building of temple are assumed that it had five rooms in front compartment until the 7th century and then it was diversified to three, five and seven compartment. The size of compartment was same in the scale of front Eokan and Hyeopkan until late 7th century, but since then the dimension of Eokan tended to be wider than Hyeopkan. It was judged that the front Eokan used triple scales like 9, 12, 15, 18 cheok. Fourth, the length of residential structures was 17.5cheok${\sim}$36cheok and Bcheok was commonly used for front side of structure, The length of official structures was 8.4cheok${\sim}$36.3cheok which is similar to residential structures. However it has been confirmed that each of 9cheok, 12cheok, and 15cheok has been used for Eokan and Hyeopkan which gave presumption that triple scales was used for the measure.

When it comes environmental preservation and economic development throughout all the industries, it is adopted to regulate carbon dioxide emissions in United Nations Framework Convention on Climate Change. And we must be responsible for promoting the eco-friendly and sustainable development because of a registration of the Kyoto protocol. Almost all the domestic buildings have many problems that not only waste the resources and architectural energy, but also are not enough to recycling of the waste. So m this study the environment-friendship is estimated through assuming carbon dioxide emissions. And after indicators are derived through surveying the residential satisfaction, it is carefully thought to develop the Smart Component that increase the length of life and the flexibility and improve the comfortable circumstance in buildings.

The importance of the digital architecture is increasing more ever. Currently, CAD and 3D programs are used as design fields, but the BIM (building information modeling) is gradually interested. BIM is mandatory on the project more than 50 billion won ordered by the government since 2012, it will be expanded to a total of government orders by 2016. University needs to evaluate teaching methods and computer-aided design environments such as CAD and BIM. In this paper, we surveyed computer-aided design environments and teaching methods for 73 students at the J University of Department of architectural engineering. Main results are as follows: 1. Hardlock is uncomfortable but necessary program for the computer management. 2. The desk placement considering the behavior of the design students results in higher satisfaction. 3. Because a CAD subject was a difficult course content and progress is fast, students thought it is difficult to follow. Especially, first-year students answered it is difficult to learn program and understand the structure of the building at the same time. 4. First-year students want to learn CAD more. Second-, third-, fourth-year students want to learn Photoshop more. Supplement for these classes is required. 5. Students answered that a teaching method of a CAD subject would be good to their own practice after the professor demonstrates for students. The senior's assistance is also a high effective way in the class. 6. During class, students' activities such surfing the web and Kakao Talk on a smartphone disrupt the class, there is a need to regulate by a rule such as disconnect computers from a network and against using smartphone. Although the Internet with the popularization of smartphones confers a benefit on modern life, it causes damage to us. This is a hard part for a salaried workers as well as students studying equally. The self management is required and a professor needs to control and restraint in a university classroom. The professor's continuing interest to students can increase the effectiveness of learning.

In the architectural space of modem age, expanding to the vertical and horizontal direction for the interaction between space and space is becoming an indispensable factor, and in this expansion, ramps are being positioned as one of the important factors. With an increased use of ramps, they show a variety of changes in types, functions and even concepts. The space where modem ramps are used exhibits a phenomenon that accommodates and expands many functions as well as the confined function of moving people, and is widening the scope of recognition on the functions of ramp. In addition, this phenomenon can be seen as an architectural reflection on the complexation trend of the modem society, the components comprising a ramp contact the body of experiencers closely and thus have a direct effect on their behavior or feeling, and owing to this, it is a space where new functions and meaning are highly likely to be derived. In this study, spaces where ramps are used stay away from an element of uniform vertical movement but have an independent environment within the entire space, thereby being used as a space dominating the nature of the building, not a subsidiary element of it. In this study, therefore, it could be known that spaces in which ramps are used are different in their meaning according to the patterns, not as an element of uniform vertical movement. In addition, these conclusions are the results by analyzing the patterns of ramps taking place in modem spaces and are thought to be helpful in understanding spaces where ramps are used.

This paper is a study of the possibility of experience and expression in the architecture of Louis I. Kahn by focusing on the characters of entrance, court and window/wall of his public buildings. In the course of composition, Kahn defined the entrance, court and window/wall as an connecting elements and elements of boundary. The characters revealed by these elements or rooms give the clue to insight Kahn's thought of relation of interior and exterior space or inner and outer space. Following are the characters of these elements. First, a entrance reveals the fact that inner space separates from outer space by connecting these two space and giving the value to inner space as the entity and totality like outer space. The entrance gives its ontological being to human subjects not by vision but experience and expression which is the essence of commonness, that is, Silence. Kahn made the possibility of activity amplify in this common and silent space. Second, this entrance is connected with wide and huge central space not individual spaces of interior space. This extreme procedure of entering makes human subject feel sublime of intoner space. And the central spaces becomes another exterior or another world in the inner world of architecture by the lights from above and by having the boundary wall which shows same pattern of exterior wall. Third, Kahn regarded a window as the giver of lights not as the medium of vision connecting inner space with outer. He tried to connect interior with exterior through the being and character of the light expressed in the interior. And in his buildings, interior space is connected with exterior by expressing the purpose of building, composition of inner space, structural truth and construction facts through the Form, a pattern of wall, details and ornamental joints. By practicing this thoughts in the real buildings, Kahn tried to gave aura to both the interior space and entity of architecture which is regarded as micro universe like flowers, rocks and human beings.

This study researched the art-educational thoughts as a modern idea influenced with the social and philosophical transitions in the 19th century. Moreover, this study focused on Frank Lloyd Wright's educational thoughts, because those educational revolutions had appeared as one of the results that Western society's character was rapidly changed by those revolutions, so called, Industrial Revolution, American and French Revolution, and Cultural Revolution of Romanticism, from late 18th century, and eventually because that revolutionary educational ideas had closely and basically many relations with Wright's thought. As a result, even though Wright's education such an apprenticeship was a traditional shape, which was not the old-fashioned educational method discipling to the skillful man, but against the existing education through the self-learning from experiences in nature. That is similar to transcendentalists such as Emerson who searched for having an inspiration in Nature. Namely, Wright himself had struggled against the existing dualistic educational concepts through Wright's monistic thoughts on art-education including architecture based on not naturalism but the philosophy of nature by romantic idealistic philosophers such as Shelling, Fickle, Kant, Hegel including with his Master, Sullivan, and by revolutionary educators such as Freobel, Ruskin, Dewey, and above all by his Unitarian doctrine. However, Wright's thoughts was at that time so radical, and as Wright himself acknowledged that, 'because the philosophy back of it, of course, as you know, is midway I guess between East and West', such all philosophical objects to influence on Wright were so abstruse idea which is usually called 'Romantic' or 'Mystic' that is mingled with East's and West's essence. That is, because Wright himself catched that the theories and methods of the art-educational thoughts would not be easily perceived, and he judged that in a word as a character which could not be taught. After all, Wright's romantic progressivist art-educational thoughts have not been perceived, disseminated in general and widely.

The purpose of this paper is a study on the dome plan of S. M. del Fiore Church of F. Brunelleschi. The results of study are as follows: 1. The planning of floor, elevation and cross section plan of S. M. del Fiore church is basically planned by each other correlation. In particular, the octangular form of geometrical standard which is formed with altar as the center at the crossing part is important component elements which is decided by not only the dome, but form and size of the drum and floor plan form of the lantern 2. The dome which has been planned by F. Brunelleshi has completed the new dome, preserving gothic thought intended by the church plan after study on architecture of ancient Rome with Pantheon. And the dome which is a main space of church through all aspects of plan, structure, function and construction about the dome is a opportunity in the beginning of Renaissance architecture which is a new epoch and a turning point of architecture on various point of view. 3. The dome which is constructed by F. Brunelleshi has been planned through the innovative solution by the refusal of traditional semicircle form dome, centering use and creation double-shell structure form for the first time in history. And the construction of dome has been solved with the invention of various construction equipments and machineries, the stone rib planned for connection and reinforcement about shells of the octangular form, the support method for reduction the gravity of bricklayers work and the brick work of nock-patterned shape which is masonry construction method of the architecture of ancient Rome.

Construction waste is recycled and used for the efficient and eco-friendly disposal of construction waste increasing due to reconstruction and redevelopment project and so on. There is recycled aggregate as a typical case. And this recycled aggregate shows strong alkalinity due to calcium hydroxide, and causes many environmental problems. Therefore, this is a study on reduction in the strong alkalinity of recycled aggregate by using sodium phosphate based ammonium in order to reduce the pH of recycled aggregate. Besides, a possibility that a pH reducing agent of recycled aggregate could be applied to a site was evaluated. As a result, it was possible to verify that pH decreased as the percentage of pH reducing agent increased. It is thought that the pH reducing agent can be applied to a site by methods such as immersion and spray using the pH reducing agent in the process of producing recycled aggregates.

This study aims at establishing a basic theory for the combination of architecture and movies by comparing the long-take technique of movies and the continuity of space, one of space composition principles, which is important in digital architecture based on Jacques Lacan's visual-art theory and finding common features and differences of them. The following is a summary of the conclusions. First, analyzing the long-take technique on the basis of Lacan's visual-art theory found that the subject of representation is scenes of movies and that staring shows features of narrative. Second, the long-take technique can be thought as a cinematic technique which tries to realize the real order beyond the symbolic order in real life through the process of continuous replication of replication of replication of a scene in one shot. Third, in contemporary architecture, which is compared to the long-take technique in the past, the inclined space of opened gaze is similar to the method which tries to realize architectural space of the reality which belongs to the symbolic order close to the real order which belong to significant in human unconsciousness. Fourth, the freeform continuous space of closed gaze, which can be compared to contemporary long take combined with computer graphic technology, has more difficulty in realizing the real order than the long-take technique in the past and inclined, continuous space as the feature which belongs to $signifi{\acute{e}}$ in human consciousness has been strengthened through the circulation which repeats and expands along an observer's movement. Fifth, when the contemporary long-take technique and freeform continuous space expand gaze which opens from the inside to the outside, it is considered that the space which is closer to the real order than the classic long-take technique and inclined continuous space can be created.

King Seong carried out the large-scale construction transferring the capital from Wungjin (Gongju) to Sabi (Buyeo) in 538. But because most of the Buyeo area was the low swamp in the time, it needed above all to form a site before transferring the capital. Until recently, in addition to the scientific excavation, the relief excavations for the construction of new building or the formation of road were conducted on many sites in the Buyeo area. As a result, many remains which were formed on the low swamp including the temple site of Neungsan-ri, Dongna Castle, the remains of Ssangbuk-ri (280-5 Bukpo, Hyeonnaedeul) and the remains of Gua-ri were identified. Also in these remains, the various engineering construction methods irrespective of the nature of remains were used for the purpose of the soft ground reinforcement as follows: mattress method of construction, pile designation, stone alignment, filing of decomposed granite soil, culverts and storage tanks. Especially, the mattress method of construction and the pile designation are thought to be the traditional engineering construction method at least in that they are appeared since the Three Han Sates era. And these soft ground construction methods had an effect on the construction of reservoir in Japan at the time. In the future, the construction method for soft ground reinforcement shall be concerned and studied further in the architecture and the civil engineering as well as the archeology.
