The Seoul Housing Corporation pronounced an alternative design competition and a bidding for Eunpyeong New Town in December of 2004. At first many construction companies were interested in the first New Town Project. But at last a few companies had proposed the alternative design and construction cost. This project needed a conjunction of design ideas and technology know-hows. And the client wanted the brand power of construction company. Ultimately the Corporation hoped that the first New Town Project will end up with high quality successfully. This competition had started with the original construction drawings. Then it needed some alternative ideas and the lowest cost. There were two drawings of non changeable part and changeable part. Non changeable parts are structure like housing unit plan, underground parking lots. Changeable parts are outdoor layout, interior design and building facade. So we tried all ideas of landscape technology and design principles within limited guidelines. The author applied new technology like tilted rooftop greening and sustained container greening on high-rise apartment house. This green technology will be the first trial in Seoul and in the world as well. Daewoo Corporation have accumulated greening technology through the researches by national funding since 2002. Through this New Town Project the green technology will go forward step by step.

PIN-entry interfaces have high risks to leak secret values if the malicious attackers perform shoulder-surfing attacks with advanced monitoring and observation devices. To make the PIN-entry secure, many studies have considered invisible radio channels as a secure medium to deliver private information. However, the methods are also vulnerable if the malicious adversaries find a hint of secret values from user's $na{\ddot{i}}ve$ gestures. In this paper, we revisit the state-of-art radio channel based bimodal PIN-entry method and analyze the information leakage from the previous method by exploiting the sight tracking attacks. The proposed sight tracking attack technique significantly reduces the original password complexities by 93.8% after post-processing. To keep the security level strong, we introduce the advanced bimodal PIN-entry technique. The new technique delivers the secret indicator information through a secure radio channel and the smartphone screen only displays the multiple indicator options without corresponding numbers. Afterwards, the users select the target value by following the circular layout. The method completely hides the password and is secure against the advanced shoulder-surfing attacks.

The purpose of this study is to develop machine embroidery textile designs for each technique that can be expressed using a single-headed computer embroidery sewing machine through a machine embroidery CAD system. For research, embroidery CAD utilized the Artistic digitizer, and the guillotine computer-mechanical magnetization machine used ELNA. The design concept was limited to portraits and relics of independence activists in six memorial halls built in Korea. The results of this study are as follows. First, it was found that the machine embroidery texture, which could only be produced by industries in the past, can be expand in the infinite creative embroidery design area by enabling the digitalization of motif images and the simulation of machine embroidery techniques through various layout options. Second, in the development of machine embroidery textures, it was found that the setting of the width, height, axis ratio, stitch, object, path, length, density, layer order, etc. in embroidery CAD is a very important part of determining the completeness of the embroidery results. Third, mechanical embroidery textile designs, which can be represented by single-head computer machine embroidery machine were able to show colorful embroidery results that differs from the original image by using seven main techniques and five deep technique alone or in combination, according to the designer's intention.

This paper is one of the sequels from 'A Survey of Villages and Dwellings of Korean Immigrants in the North-Eastern Part of China'. It is the result of the extensive survey of Ch'ang-ts'ai-tsun village and covers several architectural characteristics of the dwellings. This paper alma to identify the 'double file' dwelling type, which is believed as one of the main stream of Korean folk dwelling. In this type, 'Chung-ju-kan' forms the central open space, where main household functions are carried out. This type originates from climatic reasons and functional reasons as well. This paper also aims to clarify how the dwelling forms are changed according to the life styles of various periods. The Korean immigrants in this village have experienced rapid changes in modern times like other Chinese. Through various political movements, the original dwelling type of this village has changed to adapt various needs and functions, which shows the simple truth : dwelling form changes according to the changes of life style and social structure. In this paper the directions of chimney through various periods are analyzed to verify the differences of the house layout methods and concepts of the time. The village had grown through 3 main periods before liberation period(1946), communization period(1946 - 1966) and contemporary period (1967 - ). It is concluded as follows: 1. The village was originated in late 19th century along the east-west street, which was a major routes of Korean Immigrants to China. In this area there was no regularity in its site plan. The direction of chimney, which was usually westward, was not determined according to the location of gate. This type was kept until liberization of this area, 1946. The plans of dwellings followed Ham-kyong-do 'double file' dwelling type, '6-kan dwelling' or '8-kan dwelling'. 2. The 'New Village' area, which was formed in the communization period, has a strict regularity in its site plan. The direction of chimney was determined as opposite direction of the gate. This method was maintained until 1976, when Mao died and new 'open' policy was held by Chinese government. In this area the 'dwelling house' plan type was not changed, but its layout and size were restricted. The general form of the dwelling in this village was shaped in this period. 3. The contemporary dwellings were built in random site location. The dwelling type was changed because of the reduction of family size and the permissin of private ownership. The number of rooms was reduced but the storage rooms and domestic animal hutches were added. But the 'Chung-ju-kan', the major chacteristics of north-eastern Korea dwelling is still kept. It becomes one large 'Chtin-ju-kan' room like 'open plan' type.

Kyedan(戒壇) is an altar to perform a rite of Buddhist Initiation which gives Precept to a Buddhist monk. Sometimes it is called the Place of Precept and Mandala by Sanskrit. In this study, the Sutra of the Tang(唐) Dosun(道宣) regarding First Kyedan of Jetavana-anathapindasyarama(祇園精舍), which was the first temple such as, Kyedandokyung(戒壇圖經), Kiwonsadokyung(祇洹寺圖經), Sabunyul(四分律) were analyzed to find out original form and layout. Ultimately, the study was intended to examine the spatial formation-principle by comparing with Kyedan Temple. The results of this study could be summarized as below. First. Except for Kyedan in Bakryensa, the height of lower stone plate of Buddhist Bell-Shaped Stupa of Korean Kyedan is higher than three storied Kyedan that described in Kyedandokyung. Second. Buddhist Bell-Shaped Stupa above Kyedan was presumed that embodied image of Bell Pedestal and symbolism of overturned-bowl were combined together, when Kyedandokyung and Kiwonsadokyung were referred. It could be examined by the existence of stone lantern. Third. In Korea, the rite of Buddhist initiation that gives Precept in Kyedan has been considered impossible. However, when the rite was conducted, there was a possibility to establish wood stair. It is because that the Buddhist Stupa of Silleuuksa(神勒寺) and Woljeongsa(月精寺), which reflected the image of Kyedan had stone stair. Fourth, The method to build Kyedan of Dosun divided into Large Region and Small Region was applied to the method to construct Stone terrace behind Jeongmyeolbogung(寂滅寶宮) like Tongdosa(通度寺) and complete Kyedan on the stone terrace. In other words, Jeongmyeolbogung became Kyedanwon(戒壇院) and Kyedan, itself became Small Region. The area of Stone terrace became Large Region and naturally, they constituted an Institution. Fifth, Korean Kyedan which is consist of Jeongmyeonlbogung and Kyedan is a Korean original composition principles of Kyedangaram(戒壇伽藍) that can satiate all the functions of Kyedan as a religious subject and the place of the rite of Buddhist initiation, as it had complex of Outdoor Kyedan, which was suggested by the sutra of Dosun and Institution of Kyedan.

When historical or cultural buildings need to be repaired or reinforced, the changes of original features should be minimized, and the strengths of structures should be improved. Among the existing methods to reinforce historical wood structures, the carbon fiber reinforcement polymer (CFRP) installation method is one of the best ones to achieve the afore-mentioned requirements. Therefore, this study aims at investigating the reinforcing effects and failure modes of timber beams reinforced with the inserted CFRP, a part of roof trusses in modern wood structures, and at providing the fundamental test data to estimate the CFRP rein-forced timber beam in the application of this reinforcing method. The primary parameters in this study were the layout and amount of CFRP. It was observed that, when $0.3{\sim}0.7%$ of CFRP were installed, the strengths of reinforced timber beams increased up to 173% compared to its original strength, but their strengthening effects were heavily influenced by the characteristics of timber such as burls. In order to improve the applicability of this strengthening method, fundamental understandings on the characteristics of wood would be necessary, and there would be in need of researches on the non-destructive test for wood structures as well.

The purpose of this study was to seek the spatial organization and prototype landscape through literature reviews, historical evidences, and field surveys for Donggwanwangmyo(東關王廟) shrine in Seoul. The results were as follows : First, the basic layout of the main buildings in Donggwanwangmyo which is the remains influenced by China had bilateral symmetry on the central axis between the north and south. Second, the Chinese forms and features were found at Jeong-jeon and middle gate in Donggwanwangmyo, and the symbolic elements of royal authority was also found in each space of Donggwanwangmyo. Third, spatial organization was classified as the entrance and the ritual area, and the entrance area was maintained by administrators and was used as the place of ritual ceremony preparation. Fourth, the original form of Donggwanwangmyo had been damaged due to the project for making urban park in the 1970s. The most of the existing trees and shrubs which are not suitable to the shrine should be removed to recover the original landscape of Donggwanwangmyo and chui-byoung(翠屛), pond, landscape facilities also needed to be restored. Fifth, Donggwanwangmyo needed to reorganize the pious atmosphere to recover of the shrine environment, and needed to be reclassified as historical site. Finally, some criticizes that Donggwanwangmyo is the result of Toadyism, but Donggwanwangmyo can be used as the valuable tourism resource through the awareness that Donggwanwangmyo was built under the situation of Joseon Dynasty, and organization and understanding that Donggwanwangmyo is a symbolic remains for the exchange between Korea and China.
