In design standards such as AASHTO LRFD and Korea Highway Bridge Design, the dynamic behaviors under the impact loading has not been considered and it recommends of using a static force for designing bridge column against vehicle collisions. Accordingly, in this study, models of vehicle collisions to concrete bridge column were developed with various boundary conditions in order to take into account dynamic behaviour of the column. Cargo trucks of 10tons, 16tons and 38tons were selected and a typical type of concrete bridge pier column along the Kyungbu highway in Korea was selected for this study. Results from this study indicate that the static load specified in the design standards are too small compared to results obtained in this study. It was also found that a consideration of the bridge superstructure allowed smaller damages of concrete bridge pier column under truck impact loadings. Furthermore, a comparison study of direct impact analysis of vehicle to bridge-column with in-direct impact analysis using load-time history functions was performed. The in-direct impact analysis shows that the use of load-time history graph improves the computational cost up to 92% and predict the behaviors of the bridge column under the impact loadings well. The obtained load-time history graph could be easily applied to several existing models.

Recently, the renewable energy resources play an important role as an energy resources of future due to an environmental pollution and lack of resources and so on. The development and diffusion of information systems related to renewable energy resources have been driven actively abroad. However, at domestic an efficient history management for renewable energy resource data and web retrieve service are not provided. Therefore, in this paper, we propose a history data management system for the renewable energy resources, which stores and manages vast history information of renewable energy resource data systematically. This system collects renewable energy resource data in the outside observation system and stores them in the history database. The stored Information is retrieved through the history query process and can be provided in various forms - table, graph, chart and counter line, etc. - on the internet. Especially, the proposed system manages the history data in real-time so the latest information is always provided to the users through the web interface.

The history repeatedly shows that designers have sought their creative inspiration from fine arts. was also influenced by contemporary art such as surrealism or installment works. This thesis aims to examine the inter-relationship between contemporary art and contemporary furniture design with examples of organic modernism and minimalism furniture design. Also, will be analyzed in light of such interdisciplinary relationship, explaining the significances of in scholastic perspective. The previous research analysis of finding out examples of how fine art and design sought mutual exchanges to develop will help to examine the significance of in the context of art history. This analysis could be used as an important academic material to understand the origin and characteristics of modern design furniture. The features of surrealism and minimalism will be discussed in light of their influences on and interactive relationship with organic modernism furniture design. This provides important basic material to further analyze . Furthermore, the artistic language and plastic features of contemporary sculptors and installment artists such as Jean Arp, Richard Serra and Anish Kapoor will be examined to show how integrated and combined main features of those artists. extracted cognitive and phenomenological aspects from Serra's works that overwhelm viewers with their massive scales. Somewhat abstract yet somewhat primitive and dynamic features of Arp's works was also referred to . are made of FRP, composed of three partitions and six stools. This work was analyzed in aspect of form, composition and function. They have organic and flexible formations with free composition availability which endow free disassemble and arrangement. Also, they have cognitive features as of small elements are freely dispersed upon spaces to bestow certain presences. Based on this, this thesis could develop scholastic researches that examine the mutual and interactive relationship between contemporary art and furniture design with much more detailed discussions and examples.

The purpose of this study is to analysis the influence in furniture and interior design of pop design. Pop design is a trend which was in fashion for a short time between 1950s and 1960s. It is an experimental transient form in a flow of postmodernism. Through such a trend, we can analogize an idea and values of people speaking for a rapid change of society and culture chat that time. Therefore, the purpose of the study is to examine what environment of society and culture and what idea had an effect on people at that time. Also, the study will examine how the above had an effect on interior design and furniture design. Considering the above results, the study will examine an influence and meaning of pop design in design history. According to the result of analysis, characteristic of pop design is anti-modern, expendability, future mood.

In seismic analysis, there are two main ways - uniform load method and dynamic analysis, dynamic analysis can be divided into response spectrum analysis and time history analysis. In case of which get the complexion of the vibration with 3-axis of coordinate direction in each mode of free vibration mode happened owing to complication of the shape, 3-dimensional dynamic analysis is recommended to perform as multi-mode spectral analysis in standard specification for highway bridge. The purpose of this study is to understand the dynamic behavior by performing multi-mode seismic analysis according to responses analysis and time history anal)'sis in using record of earthquake. In accordance with the criterion of seismic design as defined in standard specification for highway bridge by using modified records of the El Centre and Coyote Lake earthquake, response spectrum was constructed by using the tripartite logarithmic plot. The 3-span continuous space truss bridge was selected as model of numerical analysis. As the result performed time history analysis and analysis of response spectrum for the model of numerical analysis, the result of time history analysis was slightly larger than that of response spectrum analysis. This coincide with the tendency of the result came from the analysis when using a jagged response spectrum analysis, This coincide with the tendency of the result came from the analysis when using a jagged response spectrum for a single excitation. In the Process of performing these two analysis. response spectrum analysis is more effective than time history analysis in saving times in analyzing data.

To analyze the design education of elementary school in the united states, the content of Discover art, one of the popular art textbooks for elementary school student, has been examined. Focusing on the developmental stage and sequential curriculum across all grades, design principles, color and criteria of design are investigated. The subjects studied are as follows: an introduction of new word or concept of design principles and color, repetition of the learning, the number of color taught, looking at products of design and making design at each grade level. The curriculum of design principles is well composed, but line, shape and form parts are redundant throughout all grades. The learning order of the color at one grade is well organized but the repetition is too much. The portion of design part is too small. It is adequate that the history of design is introduced at grade 5 where children start to learn history. However, it should be more strengthened for the continuous development of design ability. Looking at product design is introduced before grade 4, and making product design is taught just once at grade 4, although sequential learning is necessary in late elementary grades.

This research focuses on 10 modern museums built in Europe near important cultural assets of UNESCO World Heritage level. This study aims to reveal the coexistence of European laminated history and contemporary architecture by considering various aspects of respecting the existing and maintaining their identity as modern buildings, using these cultural assets as a basic concept of planning while minimizing conflicts with the past. The four measures of respecting existing cultural heritage are arranged by showing respect by lowering oneself, sympathizing with others, preparing for harmony with modernity, and communicating by looking at. The measures that reveal the identity of modern buildings are confirmed by classifying them as modern and post-modern approaches, each with several options. Through this study, we have been able to extract useful lessons for us, as well, while the past and present coexist successfully, by taking history as a reliable guide to take a fresh leap from it, rather than as a solidified remnant of inertness.

Active application of auger-drilled piling is expected in Korea considering its advantage in noise and vibration problems against driven piling and its cost-effectiveness in comparison to the cast in-situ piling. The current design practice being used in Korea is adopted from the Japanese one, however the equipment and construction procedure is modified for the geotechnical conditions and construction circumstances in Korea. Therefore there is an urgent need for the establishment of the rational design criteria for the auger-drilled piling in Korea. As the preliminary work for the establishment, this paper presents the current practice in Korean railway constructions. Design criteria of Korea Railway Network Authority are introduced and its characteristics and the problems are described. Application cases of auger-drilled pile to railway construction are introduced as well.

This research takes an introspective and critical approach to the college level visual communication design education in Korea. As such, the changes of the college-level visual communication design curriculum in Korea are analyzed. Selected were 3 major design schools which have a relatively long design educational history in Korea. Those 3 schools are Hongik University, Seoul National University and Ewha University. The curricula were categorized and its changes were followed. The faculty members of those 3 schools were also analyzed. The college level design education began from 1946 at Seoul National University. The Koreas design education was influenced from the Japanese Design curriculum and then the American design curriculum from the beginning. The Korean design educators accepted those new design educational paradigm without any criticism, and it is now structurized in our design educational system. It caused the curriculum with practice-centered classes mostly, and the function centered design education without understanding of socio-cultural environments. The Korean design education needs more liberal arts which will lead us to more discourses about ourselves, and needs to employ more local design educators to solve the intellectual skewness in the Korean academic society in the field of Design.
