The Cheomsungdae was built in the Silla dynasty during the reign of queen Seondeok. It has a round cylindrical structure with a flowing curved fa ade. The identity of the Cheomsungdae has not been revealed since there is not much historical evidence or documents about the building. This study is trying to investigate the building technique and method from the technical point of view of the past when it was constructed. There have been much work and studies done for the Cheomsungdae, but not much were focusing on the technical aspects of the building. In addition there are many questions and doubts about the hypothesis of the building technique of Cheomsungdae since there aren't any remaining documents or historical evidence supporting it. Among many questions, we think that the discussion on falsework technique is not considering traditional construction method of the Dujabee (a traditional construction technique using various tools and equipment for the stability of the building) technique. Therefore, it is hard to identify them as reliable historical facts. As the result of the study, we want to provide the basic data on the construction techniques of Korean traditional architecture and broaden the study scope of technical history by narrowing the errors. The study could be summarized into three points. 1. The historical architecture Cheomseongdae was constructed by using traditional crane techniques such as a Noklo (pulley ladder). Cheomseongdae was re-evaluated as a high level technology for the history of architecture. 2. The benchmark method on Cheomseongdae construction has been applied with a precise scientific method based on the geometrical principals using the central axis. 3. In terms of the history of Korean traditional architecture technology, as there aren't many studies done we proposed various basic data for the traditional crane techniques and criteria of Korean traditional architecture technology. We could expect various and active studies for the technical approach of the history of architecture.

The Axes and Adzes are the oldest tools since the beginning of human history which is used to cut the tree and make part of architecture such as boards, square timber etc. Nowadays, these old woodworking tools especially "Jagui(자귀)" (adze) has been almost disappeared at the working site of residential and cultural properties. It is necessary to study Korean traditional woodworking tools to keep Korean traditional skill and technology. It has been reviewed the change of shape of "Jagui(자귀)" (adze) from before Samhan (삼한) period to Joseon Dynasty through excavated relics and paintings and summarize as follows: Based on excavation relics of Dahori, both plate type blade and pocket type blade are used for "Tokki(도끼)" (axe) and "Jagui(자귀)" (adze). The excavated "Jagui(자귀)" (adze) from Jeongbaikri 356 tomb, near Pyongyang is prototype of "Jagui(자귀)" (adze) used nowdays which has almost same shape as well as the insert method of blade and handle. The auxiliary handle is inserted to blade and the main handle is inserted to the auxiliary handle which is different from the method of Chinese and Japanese "Jagui(자귀)" (adze). The length of handle of "Jagui(자귀)" (adze) until late Joseon Dynasty is short by which we assume it is used for a sitting position as hand held Jagui and from that time long handle has been introduced for a standing position which is called "Sunjagui(선자귀)". "Jagui(자귀)" (adze) has been used since the beginning of human history but it is almost disappeared at the most of woodworking site which is the crisis of Korean traditional architecture and we have to do something to keep it.

This study contemplates the tendency of the examination questions for History of Korean Landscape Architecture. The study targets the questions of 'Landscape Architecture History' which has been set in the written test for National Qualification Test of a landscape engineer for recent 10 years from 2005 to 2014 and derives analyzable items based on the guidelines of question-setting presented by Human Resources Development Service of Korea. The results of the study are drawn as follows. First, among 5 areas composing Landscape History, the proportion of Korean Landscape questions is getting increased while that of Western ones is decreasing. Second, about 30 traditional trees and 11 types of traditional landscape elements including traditional facilities were shown in Korean Landscape questions. Besides, history, geographic, practical science, horticulture, anthology books and the 25 tradition landscape-related historic documents categorized as the garden painting data were found. And the kings from ancient era to Choseon Dynasty who were associated with the time of palace garden building, the builders or owners of the villas, the authors of the document and Chinese scholars also appeared. Third, there were no the questions of prehistoric times and Balhae Kingdom, whereas those of Choseon Dynasty were dominantly focused. Among the traditional sites of Choseon Dynasty, Byeolseo(villas) were set most, followed by Dosung or Gung-gweol(castle towns or palaces), houses, Nu Jeong Dea(pavilions) and Seowon(local schools) in order. Nak-an eupseong and Yong-ju sa were the only cases for a castle town and a temple each. Fourth, being associated with tradition spaces, the questions asked for understanding the detailed contents of time of sites' construction, builders, location features, building structures, ground plan types and the components s of garden. In addition, as a result of checking whether traditional landscape sites were shown in the set questions in 9 Korean Landscape textbooks, Dongchundang, Pungamjeonsa, Simgogseowon did not appeared. As a result of reviewing the tendency of the examination questions for History of Korean Landscape Architecture, the questions which ask minor facts without generality and which include difficult information and site uncomprehended in the textbook should be reconsidered.

If we compare socio-cultural aspects of the two historical periods known as 'pre-modern' 'modern,' it would seem that the Aristotelian understanding of technology has difficulty explaining techno-cultural phenomenon of modern society. The problems are first that the discourse of scientific technology in the modern period has proceeded without a metaphysical base, and second that nothing in present culture regulates the limitations of scientific technology. The clear distinction between means and ends in the traditional approach is no longer valid in the jumble of interrelationships. Such complexity forces us to acknowledge that means and ends are relative and interchangeable, and that neither has a clear moral superiority over the other. Technology in modern society is no more a neutral means. The products of science do not always exist to serve human ends. In modem architecture and urban design, both its productive and destructive tendencies leave man and his society in an endless confusion of complexity and opposition. These problems of technology still result in unsolved question today. On this point, the discussion another currently prevalent attitude to technology, especially Heideggerian thinking in the below could give a somewhat clearer answer to the problem of modem architecture and technology, although it also comprises limited contemplation in itself.

In this paper, we present a CNN-based gesture recognition approach which reduces the memory burden of input data. Most of the neural network-based gesture recognition methods have used a sequence of frame images as input data, which cause a memory burden problem. We use a motion history image in order to define a meaningful gesture. The motion history image is a grayscale image into which the temporal motion information is collapsed by synthesizing silhouette images of a user during the period of one meaningful gesture. In this paper, we first summarize the previous traditional approaches and neural network-based approaches for gesture recognition. Then we explain the data preprocessing procedure for making the motion history image and the neural network architecture with three convolution layers for recognizing the meaningful gestures. In the experiments, we trained five types of gestures, namely those for charging power, shooting left, shooting right, kicking left, and kicking right. The accuracy of gesture recognition was measured by adjusting the number of filters in each layer in the proposed network. We use a grayscale image with 240 × 320 resolution which defines one meaningful gesture and achieved a gesture recognition accuracy of 98.24%.

Since 2002, Architecture Schools in Korea was changing long traditional architectural education system from 4 years generalized architectural engineering curriculum to 5 years professional architecture program. Until 2010, 76 architecture schools have changed their program to 5 years course which was focused to design studio education. It was a very rapid change and there was not much time develop their own system which could represent institutional identity, character of students and local environment. Korea joined as a regular member of Canberra Accord in 2010 and it is meaningful to compare Korean architecture program contents to another country education contents. US architecture programs were selected for this comparison study. The goals of this study are to create a comparable understanding the form of contents of Architectural Education in US and Korea and to verify the substantial equivalence of these systems. To achieve above goals, three public institutes of each country were selected and analyzed with general information, history, resources, curriculum and the matrix of Student Performance Criteria for quantitative comparison. For qualitative comparison education context of programs were analyzed with program missions, the way of advising, professional connection and distribution of faculty loads.

To consider an identity about traditional folk village, this study analyzes color characteristic of traditional folk village by targeting Cuandixia folk village in China. For method of study, color is analyzed by KSCA(Korea Standard Color Analysis) program and images of color are drawn by I.R.I. Based on these, four results are came out. First, color distribution of Cuandixia is appeared in YR, R, Y, GY order. Furthermore, there are no affiliation of BG, and B but a lot of affiliation of YR. Second, the whole is made up of color that is applied to mist gray/low chroma in the value and chroma stakes. Especially, high chroma is extracted by only commercial old house, the rest is made up of middle and low chroma color. Third, dark color is the most by KS Color System and dark reddish gray and medium gray are occupied most part. Fourth, the whole atmosphere of village is static and hard, and the image is researched as gentle. Through the research, It applies extracted color palette for plan and preservation of traditional folk village. As using the color that is reflected in national and local distinct characteristic, preserving the color reflected in history and culture of the village, and applying color planning considered harmony with surrounding environment, it is expected that it can help to direct the color involved traditional and cultural meaning.

The traditional Korean heating system ondol, one of the most important characteristics of Korean architecture, still remains as hydronic floor heating. Various studies have been conducted on the modernization of ondol, but the process of introducing the hydronic floor heating has not been seriously studied so far. Therefore, this paper aims to demonstrate how the hydronic floor heating had been introduced to Korea, taking the 1950s and 1960s Haengchon, Jongam, and Mapo Apartments for example - these three are regarded as the first Korean apartment houses after the Korean War. While Western advanced construction technology was imported for these apartments, various methods of modernizing ondol were also considered. What was remarkable in these attempts is that hydronic floor heating first appeared in Mapo 1st Apartment in 1962, because this is the universal heating method in the present Korea. This fact signifies that the traditional principle of floor heating has been maintained, and it would also be meaningful in terms of architectural exchanges between East and West, if considered along with Wright's application of the Korean heating principle to his houses since 1930s.

This research aims at proving the fact that the forms, spaces and many other design concepts of Modernism are much related with the changes of materials, struc-tures, and the way of construction as well as the idealis-tic and aesthestic things through the history of steel, one of the most important materials of the style. The meaning steel has in the modern architecture can be studied in the structure and industrial production system. 1) Steel frame broadened the range of understanding the space and created the new form through the skeleton/skin structure by reinterpreting the existing space fac-tors while it was being adopted to the architecture. Walls could be freed from the traditional function of bear-ing wall and roofs gave the transparancy to the interior by being linked with the glass. Posts lost the function which confines the space in the frame of the grid system and gave the flexibility to the interior due to the economical materials. These changes made the movable partition, screen with various materials and the system furniture which divides the space more important. 2) In the aspect of the industrialized architecture, it be-came the moment that the most of the archtectural com-posing parts were in mass production as they were standarized, high qualified, and generalized by the indus-trial characteristics of steel, and the specialization of structure and cladding, but the neither of the efforts to make the building itself by mass production or to standarize it was fulfilled. The high-tech architecture which borrows its archtectural manifestation from the high technology, however, is consistently paying efforts on such industrialization.
