  • Recently, a structure has been large and high under the improvement of construction technique. So, mass concrete constructions that a mat foundation thickness of structure is over 80cm have been many. Also, in the reason of high strength of concrete, a matter of thermal crack became an important task to be solved. In this study, we executed temperature and stress analysis of mat foundation. And we evaluated quantitatively about the possibility of thermal crack by using hydration heat analysis program. Because of this analysis technique, we could control skilfully the quality of mat foundation in a construction.

  • Due to the social problems including recent economic crisis and unemployment rate increase, the demand of business foundation market has been increased and, in the meantime, on the basis of the business foundation support policy of the government including youth foundation support policy and Small & Medium Business Administration foundation planning, business foundation market has been showing steady growth trend. With this enlargement of foundation market, as the accompanied increase of franchise market is expected, it is considered that the importance of more realistic and concrete research about franchise market be larger than before. This study considered brand image, main office support, foundation cost, information search activity as the advanced variable of effect on brand selection and established the cause of effect on brand selection by improving the existing advanced research, and its result is as follows. First, according to foundation business kind, age, sex, yes or no of marriage, there is some difference III the thought about brand image and foundation possibility. Second, Second, the most important factor of franchise contract intention is economical specificity. It is difficult to consider brand image, franchise support and information search activity as the property having a big effect on preliminary founder, and it was shown that the cost for franchise management(Consistency with initial foundation cost and self-capital, promotion cost, management fund, facility/equipment reinvestment, etc.) is an important property. Specially, it was shown that consistency with initial foundation cost and self-capital is the most important factor for preliminary founder.

  • This study aims to reflect experts' opinions in analyzing a design thinking as foundation of multidisciplinary education. For this purpose, a delphi survey was conducted with 20 experts in three sessions from May 1 to June 25, 2012. To analyze the collected data, descriptive statistics, including frequency, percentage, the mean, and standard deviation were implemented, and internal reliability test on the survey instrument was carried out for statistical processing. The main results are as follows : First, the delphi analysis on intuitive thinking of design thinking suggested 7 items(to pursue the possibility of outside, to pursue the possibility of applying new forms of technology, content planning, facing a complex real-world phenomena etc.). Second, the delphi analysis on logical thinking of design thinking suggested 7 items(executed repeatedly, reasoning and verification, artificial intelligence, a decision support system etc.) Third, the delphi analysis on subjective thinking of design thinking suggested 9 items(user experience measuring, user satisfaction ratings, user requirements analysis, user interface design, behavioral responses of the human etc.). Fourth, the delphi analysis on objective information of design thinking suggested 8 items(information management system, simulation, production process, information exchange and sharing etc.). According to the results of the delphi analysis, design thinking can be seen as the foundation of multidisciplinary education. Suggestions were made for discussion about the main results and further researches.

  • This study aims to establish the foundation for a simultaneity research, draw the potential through Bergson's simultaneity, and explore a space with the possibility of a continued change, focusing on the simultaneous process, in which physical mobility and consciousness of space last together. First, this study was focused on understanding Bergson's simultaneity, on the basis of the perspective that space needs to have more active, dynamic mobility. For understanding Bergson's simultaneity, the understanding of Bergson's duration conception, memory and perception was preceded. After that, the characteristics of simultaneity were extracted from the concepts of duration, change, memory and perception and its characteristics, which are connected to space, were analyzed. As a result, the study on simultaneity that was intensively analyzed, based on diverse cases, re-awakened the basis of value or thought, which we must aim at, in space design of the present time. This shows the possibility of another creative form that can be found in spaces of the present time and serves as the foundation to discover an essential and potential value of space in space design. Moreover, the combination of space with science, humanities, art and digital media technology demonstrated once again that there is a good possibility of approaching non-representational space that is pursued today and it is anticipated that using Bergson's simultaneity as a medium for spatial combination in their relationship would help in drawing deeper internal meaning and potential of space.

  • As concrete is most usable material in construction industry it's been required to improve its quality. Nowadays, nanotechnology offers the possibility of great advances in construction. For the first time, the nonlinear buckling of straight concrete columns armed with single-walled carbon nanotubes (SWCNTs) resting on foundation is investigated in the present study. The column is modelled with Euler-Bernoulli beam theory. The characteristics of the equivalent composite being determined using the Mori-Tanaka model. The foundation around the column is simulated with spring and shear layer. Employing nonlinear strains-displacements, energy methods and Hamilton's principal, the governing equations are derived. Differential quadrature method (DQM) is used in order to obtain the buckling load of structure. The influences of volume percent of SWCNTs, geometrical parameters, elastic foundation and boundary conditions on the buckling of column are investigated. Numerical results indicate that reinforcing the concrete column with SWCNTs, the structure becomes stiffer and the buckling load increases with respect to concrete column armed with steel.

  • This study is to investigate the possibility of legislation that is the foundation of school complexation project and the architectural planning for the target facility as stipulated by related law. Since 2000, many schools have been established and operated in the whole of Korea, mainly in Seoul. However, on the frontline, there is still a lot of difficulty in carrying out the project due to the legal possibility related to the school complexation and the lack of understanding about the facility for school complexation as stipulated by the law. The purpose of this study is to present the possibility of the school complexation project based on related laws and to clarify the classifications of school complexation facilities which are stipulated by the related law, and to propose the foundation for the future school complexation project. The contents of this study were investigated through the literature survey on the theoretical review and related laws of school complexation, and various laws related to school complexation were classified based on this, and the possibility of school complexification prescribed by each law was analyzed. In addition, by classifying facilities subject to school complexation prescribed by the Act and analyzing the detailed standards stipulated in relevant laws for each facility, we propose the facilities that can be combined with school facilities, and utilize the data of this study.
