The present study is about a brand development strategy that utilizes Korean traditional patterns. The global culturenomics phenomenon confirms the value of the cultural aspects of design when a national brand is established. People succeed with their unique aesthetic sense and reinterpret it in a modern view, and this design acts as today's national brands. In this way, people used traditional patterns and original designs, along with regional characteristics and formative style, in developing their designs. However, due to recent changes in the global environment, modern people live in an "untact" world, and consumption culture shifted toward online marketing. In this environment, where one is isolated from social activities, there needs to be a strong image that can dramatically change the mood of one's home. I would like to re-examine the Dan-Chung pattern, whose painting depends on the aesthetic characteristics of architecture to protect the wooden members of the framework in traditional architecture. The pattern and color of Dan-Chung, coated in traditional architecture, differs by the type of construction used, which includes a palace, a Buddhist temple, and a Confucianism Dan Chung. The Geummoon pattern contains aesthetic factors to add solemnity to the Main Buddhist Halls, which contain Buddha. This is a new medium that continues the current traditions instead of remaining in the past. Among different Dan Chung patterns, Geummoon has magnificent decoration consisting of the highest grade materials and unique composition; therefore, it is suitable to be reinterpreted in modern terms. The same pattern can be interpreted in different ways with different colors, so there is a great aesthetic impression in the Geummoon pattern. The value of preservation for exploration and theoretical study of the traditional pattern is important, but recreating the pattern into modern formative art can present a new angle of view and national brand, bearing pride in our cultural assets. The study used multidimensional molding methods for realistic presentation after going through the two-dimensional design process. The significant value of Korean molding beauty which hangs onto the past will play a crucial role in establishing our national brand.

In this study, the development performance of the head bars, which is SD700, was experimentally evaluated at the RC (reinforced concrete) or SFRC (steel fiber reinforced concrete external beam-column joint. A total of 10 specimens were tested, and variables such as steel fibers, length of settlement, effective depth of the beam, and stirrups of the column were planned. As a result of the experiment, the specimens showed side-face blowout, concrete breakout, and shear failure depending on the experimental variables. In the RC series experiments with development length as a variable, it was confirmed that the development strength increased by 26.5~42.2% as the development length increased by 25-80%, which was not proportional to the development length. JD-based experiments with twice the effective depth of beams showed concrete breakout failure, reducing the maximum strength by 31.5% to 62% compared to the reference experiment. The S-series experiment, in which the spacing of the shear reinforcement around the enlarged head reinforcement was 1/2 times that of the reference experiment, increased the maximum strength by 8.4 to 9.7%. The concrete compressive strength of SFRC was evaluated to be 29.3% smaller than the concrete compressive strength of RC, but the development strength of SFRC specimens increased by 7.3% to 12.2%. Accordingly it was confirmed that the development performance of the head bar was greatly improved by reinforcing the steel fiber. Considering the results of 92% and 99% of the experimental maximum strength of the experiment arranged with 92% and 110% of the KDS-based settlement length, it is judged that the safety rate needs to be considered even more. In addition, it is required to present a design formula that considers the effective depth of the beam compared to the development length.

Japanese government college researchers, including Sekino Tadashi(關野貞), have conducted research studies and collected data, on overall Korean cultural relics as well as Silla tumuli(新羅古墳) in the early modern times under the Japanese imperialistic rule. They were supported by the Meichi government in the early stage of research, by the Chosun government-general, and by their related organizations after Korea was coIonialized to carry out investigations on Korean antiquities, fine arts, architecture, anthropology, folklore, and so on. The objective for which they prosecuted inquiries into Korean cultural relics, including Silla tumuli, may be attributed to the purport to find out such data as needed for the theoretical foundation to justify their colonialization of Korea. Such a reason often showed locally biased or distorted views. Investigations and surveys had been incessantly carried out by those Japanese scholars who took a keen interest in Korean tumuli and excavated relics since 1886. 'Korea Architecture Survey Reports' conducted in 1904 by Sekino in Korea gives a brief introduction of the contents of Korean tumuli, including the Five Royal Mausoleums(五陵). And in 1906 Imanishi Ryu(今西龍) launched for the first time an excavation survey on Buksan Tumulus(北山古墳) in Sogeumgangsan(小金剛山) and on 'Namchong(南塚)' in Hwangnam-dong, which greatly contributed to the foundation of a basic understanding of Wooden chamber tombs with stone mound(積石木槨墳) and stone chambers with tunnel entrance(橫穴式石室墳). The ground plan and cross section of stone chambers made in 1909 at his excavation survey of seokchimchong(石枕塚) by Yazui Seiyichi(谷井第一) who majored in architecture made a drawing in excavation surveys for the first time in Korea, in which numerical expressions are sharply distinguished from the previous sketched ones. And even in the following excavation surveys this kind of drawing continued. Imanishi and Yazui elucidated that wooden chambers with stone mound chronologically differs from the stone chambers with tunnel entrance on the basis of the results of surveys of the locational characteristics of Silla tumuli, the forms and size of tomb entrance, excavated relics, and so forth. The government-general put in force 'the Historic Spots and Relics Preservation Rules' and 'the Historic Spots Survey Council Regulations' in 1916, establishing 'Historic Spots Survey Council and Museum Conference. When museums initiated their activities, they exhibited those relics excavated from tumuli and conducted surveys of relics with the permission of the Chosun government-general. A gold crown tomb(金冠塚) was excavated and surveyed in 1921 and a seobong tomb(瑞鳳塚) in 1927. Concomitantly with this large size wooden chamber tombs with stone mound attracted strong public attention. Furthermore, a variety of surveys of spots throughout the country were carried out but publication of tumuli had not yet been realized. Recently some researchers's endeavors led to publish unpublished reports. However, the reason why reports of such significant tumuli as seobong tomb had not yet been published may be ascribed to the critical point in those days. The Gyeongju Tumuli Distribution Chart made by Nomori Ken(野守健) on the basis of the land register in the late 1920s seems of much significance in that it specifies the size and locations of 155 tumuli and shows the overall shape of tumuli groups within the city, as used in today's distribution chart. In the 1930s Arimitsu Kyoichi(有光敎一) and Saito Tadashi(齋藤忠) identified through excavation surveys of many wooden chamber tombs with stone mound and stone chambers with tunnel entrance, that there were several forms of tombs in a tomb system. In particular, his excavation survey experience of those wooden chamber tombs with stone mound which were exposed in complicated and overlapped forms show features more developed than that of preceding excavation surveys and reports publication, and so on. The result of having reviewed the contents of many historic spots surveyed at that time. Therefore this reexamination is considered to be a significant project in arranging the history of archaeology in Korea.

Recently, domestic construction projects Have become more high-rised, bigger, sophisticated, so necessity of logistics and progress management through application of various management theories has also been increased and development of IT technologies like RFID can help to improve management method, although the existing logistics and progress management studies are applied only to single progress or important material. It is a basic research for integrated framework for logistics and progress management. An analysis on the characteristics of RFID tech was performed for major materials or components of each work item in office building projects. This paper will make foundation of integrated framework for logistics and progress management in construction project, utilizing RFID technology by analysing materials type like materials which can be chased and measured, materials which can be chased and measured by certain methodologies, materials which can be chased and measured by future technologies, materials which are difficult to be chased and measured. So we can effectively control logistics and progress management, appling the optimum RFID technology to each construction project, and we need to study out solution in order to overcome RFID technology limitation through development of specification counterproposal about delicate materials of the RFID technology application.

A number of studies have been conducted recently regarding the development of automation systems for the construction sector. Much of this attention has focused on earthwork because it is highly dependent on construction machines and is regarded as being basic for the construction of buildings and civil works. For example, technologies are being developed in order to enable earthwork planning based on construction site models that are constructed by automatic systems and to enable construction equipment to perform the work based on the plan and the environment. There are many problems that need to be solved in order to enable the use of automatic earthwork systems in construction sites. For example, technologies are needed for enabling collaborations between similar and different kinds of construction equipment. This study aims to develop a construction system that imitates collaborative systems and decision-making methods that are used by humans. The proposed system relies on the multi-agent concept from the field of artificial intelligence. In order to develop a multi-agent-based system, configurations and functions are proposed for the agents and a framework for collaboration and arbitration between agents is presented. Furthermore, methods are introduced for preventing duplicate work and minimizing interference effects during the collaboration process. Methods are also presented for performing advance planning for the excavators and compactors that are involved in the construction. The current study suggests a theoretical framework and evaluates the results using virtual simulations. However, in the future, an empirical study will be conducted in order to apply these concepts to actual construction sites through the development of a physical system.

There are many types of remodeling, however, engineers and architectures preferred to merge two or more separate units to one very spacious unit. Performing this type of remodeling, in the case of wall dominant apartments, requires partial removal of structural wall causing a concern of structural integrity. However, there are insufficient studies about partial removal, that is, openings. Presently, ACI standard have no clear way to evaluate the effect of opening on the structural wall. AIJ has the provision about strength reduction factor '$\gamma$'. However, this reduction factor cannot exactly evaluate the reduction effect of openings because this factor '$\gamma$' was determined through the elastic analysis. Therefore, in this study, 2 structural wall specimens were tested and many test results from previous studies were collected. Using these data, this study performed statistical analysis about strength of structural wall which have the opening in wall panel. And this study performed parametric study verifying shear strength reducing effect by opening area. In the results of statistical study, previous reduction factor show very conservative results because this equation did not consider other factors, reinforcement ratio and aspect ratio of openings, which was affect the shear strength of shear walls. Therefore we performed parametric study based on the test data and suggest new equation for shear strength reduction factor '$\gamma$'.

In the perspective of hybrid, design contains confused forms and styles. Thus, the question is what 'decisively affects' on life, happiness and peace of human beings: In the past scientific ecology that tries to solve the problem in the aspect of functional design was important. Now the question is beyond the scientific ecology because human has a different way of environmental adaptation from animals. From this point of view, design is defined as something beyond materialistic standard. Terry Eagleton said, 'Creative ability deviating oneself and transcending is the very standard to measure human beings' A tendency to hybridize one's own section off genre or pursuing dismantlement is found on such creative perspective. In other words, it focuses on making a space of human's cultural behavior by unifying creatively natural environment and architecture space in the organic aspect. Such phenomenon provides a new chance and possibility in environmental design through a new molding experiment according to the development of digital technology. As experiments of environment design using digital technology are actively implemented, ecological and cultural views hybridize to create a new cultural space of various functions and features. Such experiment in environment design highlights the connections of ecological view, recognition of value, and relation-centered ideas, and enables a tool pursuing a new cultural development. This study focuses on the paradigm of such digital hybrid design and purposes to set the system by analyzing the application styles and principles of environment design through theoretical and case studies. In addition, it promotes a new possibility to develop environment design in the history of civilization.

We have developed an inversion code for three-dimensional (3D) resistivity tomography including the anisotropy effect. The algorithm is based on the finite element approximations for the forward modelling and Active Constraint Balancing method is adopted to enhance the resolving power of the smoothness constraint least-squares inversion. Using numerical experiments, we have shown that anisotropic inversion is viable to get an accurate image of the subsurface when the subsurface shows strong electrical anisotropy. Moreover, anisotropy can be used as additional information in the interpretation of subsurface. This algorithm was also applied to the field dataset acquired in the abandoned old mine area, where a high-rise apartment block has been built up over a mining tunnel. The main purpose of the investigation was to evaluate the safety analysis of the building due to old mining activities. Strong electrical anisotropy has been observed and it was proven to be caused by geological setting of the site. To handle the anisotropy problem, field data were inverted by a 3D anisotropic tomography algorithm and we could obtain 3D subsurface images, which matches well with geology mapping observations. The inversion results have been used to provide the subsurface model for the safety analysis in rock engineering and we could assure the residents that the apartment has no problem in its safety after the completion of investigation works.

Science and technology information resources are major impetus for all research and development activities. Now countries around the world are seeking efficient and effective means to cope with the exponential growth of needs for science and technology information for research. In this context, it has been perceived vital to establish national infrastructures in order to extend the availability of world's science and technology information. In Korea, it has been a recurring issue to build a national science library to prevent knowledge colonization and to gain a competitive edge in the fields. It is essential to have one as a national information infrastructure to assume the role of developing a sustainable model for access to the world's science and technology information, providing permanent access to them. In this paper, therefore, some issues concerning building and managing a new national science library in Korea are examined. In doing so, the following details are dealt with in detail. First, the rationale behind building a national science library is described, Second, the functions and roles of the library are defined, Third, previous discussions and attempts to build a national science library are reviewed and analysed. Finally, possible problems and issues raised in relation to build a national science library are probed, and future directions are also suggested. In this process, the recent strategic plan for national science library, national agriculture library, and national medical library, and changing plan for Sejong city are taken into consideration as influencing factors.

This study investigates how students perceive landscape design studio classes and provides basic data to set guidelines for future student-oriented pedagogical strategies in landscape architectural design education. This study is based on the premise that the current dominant educational method, which is based on positivism, should shift to a constructivist approach, which allows students to question objective and absolute truths and restructure knowledge based on their own experiences. Unlike lecture-oriented classes, studio education relies heavily on the perceptions, attitudes, and capabilities of individual students because the nature of the class asks each student to find solutions to given project problems in creative and visual ways. Therefore, it is important to understand the psychological state of students during these classes in order to set alternative criteria for design studio education. This study contains three parts. The first part reviews theoretical discourses to understand the demands for a student-oriented educational paradigm shift and the nature of the design studio at many levels. The second part analyzes how students perceive design studio classes in terms of their satisfaction and stress levels and how studio classes affect their decision making regarding future careers. The stress levels accompanying the design process are also investigated, based on a survey of undergraduate students who are enrolled in the landscape architecture programs of four universities in Korea. According to the findings, design studio classes play a specific role in students' decision making about their future careers. Almost half of students turn out to be dissatisfied with their design education, and half of students suffer from high stress levels caused by studio classes, especially in the early phases of the design process. The findings suggest that instructors should give more attention to discovering ways to help students initiate the design process and bridge ideas and forms, provide clear guidelines for evaluation of students' abilities, and develop a more holistic approach in design studio classes that is based on individual problem-solving processes.
