This research has set up the fire protection and early suppression plan for Asan Oeam folk village which is composed of traditional wooden building instinct or complex. The results of this study are as follows. 1. The traditional wooden buildings require attentive considerations about the fire property of the Waga and the straw roofed house. Especially, as the straw roofed house has property that the transfer and development of the fire is fast. Therefore we studied on the transferring possibilities of the fire dangerous instinct through measuring the distance from of the eaves edge and trees in neighboring house. 2. This research proposes the tools for the priority protective building through consideration of fire risk and cultural priority because the fire prevention for all is impossible at the same time. 3. The most important thing is preserve the cultural identities of traditional folk village in establishing the fire hydrant and fire prevention facilities. Traditional folk village landscape should be considered.

This study investigates the design features of pilotis applied to 20 high-rise apartment housings in Korea, completed between January 2000 and August 2005. It analyzes the design characteristics of pilotis on the basis of its spatial configuration and the residents' behavior and suggests the directions of pilotis design in the future. The study finds the followings. 1) The pilotis spaces in foreign apartment housings are used mainly for communal functions such as the passages between buildings for both pedestrians and vehicles. Compared with this public use of pilotis in foreign counterparts, the pilotis spaces in Korean apartment housings are semi-private and have multiple purposes. 2) The pilotis design can be classified on the basis of the spatial configuration elements and the patterns of residents' behavior. The spatial configuration elements consist of ceiling, column, wall, and floor; the residents' behavior can be classified as viewing, resting and playing, driving and parking, and keeping privately-owned objects such as motorcycle and bicycle. 3) Two spatial configuration elements, the wall and the ceiling and two behavioral patterns, 'resting and playing' and 'viewing' are getting more attention by designers in the apartment housings analyzed in this study.

Purpose : This study aimed to find out the effects of treatments on the surface of Zirconia. Methods : To this end, we selected six treatments that have been used widely: steam cleaning, 2bar & 6bar sand blasting, grinding by green stone point, grinding by diamond bur, and grinding by diamond bur with water spray. Results : The results of our study showed that monoclinic rate increased from all six treatments. Monoclinic rate varied by treatments, ranged from 0.6% (steam cleaning) to 6.5% (6bar sand blasting). These values from all six treatments were below ISO 13356 standard, which is 25%. Also, we found that two treatments (green stone point and diamond bur) increased roughness of surface of Zirconia. Conclusion : This study concluded that phase changes of Zirconia were not significant by using six treatments we employed.

The evaluation of package temperature for fresh preservation of cucumber was investigated. The fresh cucumber is available in markets of Korea during whole seasons, for the help of farmer, distributor and consumer. Cucumbers were stored within cardboard boxes packaging covered with low density polyethylene (LDPE) at different temperatures (5, 10, 15 and 20℃). Changes in weight loss, hue angle, firmness, moisture content and general appearance (shape of cucumber) were investigated during storage of cucumbers. General appearance index with non-packaging decreased more than with LDPE film packaging at 5℃ and 10℃. During storage of cucumbers, general appearance index as freshness showed packaging effect at low temperature than room temperature. In the fresh weight loss, the packaged cucumbers were less reduced than that of the non-packaging ones. At color change, Hue angle of cucumber stored within low temperature with film packaging decreased gradually during storage. However remarkable change in hue angle were observed in cucumber within LDPE film packaging treatments of 15℃ and 20℃ storage. The effect of hue angle with packaging appears differently depending on the storage temperature conditions. The firmness and moisture content of cucumber flesh were not affected by packaging and storage temperature. In this experiment, cucumbers packaged with LDPE film at 5℃ and 10℃ were the most desirable for extending the quality. These results suggest that packaging of low temperature treatments in combination could be effective in prolonging the shelf life of cucumber.

In this study, newly developed welding consumables for EGW were welded in EH 36 TM steel plates and their welded joints were evaluated in point of mechanical properties and microstructures compared with imported consumables. Newly developed welding consumables were evaluated as good arc stability and slag fluidity, substantially the same with imported products. The tensile strength of all welded joints were sufficient to meet the requirements specified in a ship’s classification(490~640MPa) and all areas of fracture were heat affected zone(HAZ). Charpy absorbed energy values of all EG welded metals were sufficient to meet the requirements of classification(min. 34J) and those of newly developed wires were evaluated to be better than those of imported wires. As a result observing microstructures of single and tandem EG welded metals through optical and scanning electron microscope (OM&SEM), no grain boundary ferrite(PF(G)) were created in a prior austenite grain boundary and a volume fraction of a fine acicular ferrite were observed very high.

이정수 ( Jeong Soo Lee ) 한민족문화학회 2009 한민족문화연구 Vol.28 No.-

시대의 변화를 이끄는 이를 선각자라 말한다. 중국의 太虛(1890-1947)와 한국의 龍城(1869-1940) 모두 선각자적 삶을 살았던 출가 사문이다. 격변의 시공간 속에서 그들이 주장하고 실천으로 보여주었던 모습은 지금도 후인들에 의해서 계승되고 있으며, 현재의 시각으로 살펴보아도 미래를 지향하고 준비하며 오늘의 변화를 도모하는 면에서도 시사하는 바가 크다. 두 사람 이론가로서만이 아니라 실천자로서의 위상을 동시에 갖는 측면이다. 그들의 대표적 활동상은 각각 불학원과 대각 운동이라고 할 수 있다. 불학원과 대각 운동에 관해서는 이미 많은 연구자의 관심이 대상이었으며, 의미 있는 결과물도 나와있는 상태이다. 다만 이들 각각의 생애나 활동모습에 대한 연구는 있었으나, 이들을 함께 비교하는 연구는 아직까지 구체적으로 드러나지는 않았다고 하겠다. 그러나 측면에서 본 고에서는 중국과 한국을 대표하는 태허와 용성의 대표적인 활동상인 불학원과 대각 운동을 고찰의 대상으로 삼아 새롭게 조명해 보고자 한 것이다. 그 결과로 첫째, 태허와 용성모두 출가사문으로서 철저한 계율행에 바탕한 수행자였다. 청정한 지계를 근간으로 일생을 올곧게 걸어온 수행납자임에는 이론의 여지가 없다. 둘째, 이러한 청정지계행을 통해서 태허와 용성은 당시의교단내외의 모순과 불합리, 그리고 변질되어 청산하고 새롭게 하여야할 일들을 여실하게 보고 느낄 수 있었다. 섯째, 태허와 용성은 청산하고 바뀌어야할 개혁의 대상을 선언이나 건백서의 형태로 알림과 동시에 구체적이고 일관된 행동으로 실천해 나갔다. 넷째, 이들은 현실을 직시하고 미래를 준비하는 자세로 중요한 것은 교육, 수행, 연구에 두고 실천했다. 다섯째, 태허와 용성 모두 현재까지 그의 유지를 계승 선양하는 후학들이 활동하고 있다. 지금도 이어지고 움직이는 생명력 있는 존재로서의 위상을 갖는다는 점을 확인해 볼 수 있었다. We normally address the one who lead the changes, `The Enlightened one` Ven. Tai-xu of China and Ven. Yong-seung of Korea are the one who lived the lire of `The enlightened`. Fortunately the teachings which they both advocated and practiced had been preserved till today. Looking at it from this contemporary point of view, it seems so abundant in providing us preparing for the future and induce changes in the present era. The major activity that they both represent are `The Buddha`s Institute` and `The Great Enlightenment movements`. Many researchers showed interests and carried out researches on both movenrnts and its products are meaningful. However, those merely focus on the life and their activity, which resulted in lacking comparison of the two. Therefore, I focused on the comparison of the two movements and I came to the following conclusion Firstly, they both were faithful to the strict precepts according to renunciation, and no doubt at all that they both walked the right path in keepingthe precepts. Secondly, the both showed the ideas that the Sanghaha needed changes. Thirdly, they both proclaimed and clearly written out the suggestions that needs reforms, and both lived the lifein accordance with it. Forthly, they both faced the reality and excelled in preparing for the future, actual practice and doing researches. Fifthly, the both had disciple who maintained and preserved the spirit of the movement till today. Sixthly, the spirit of the two still alive today and there seems no expiration.

본 연구는 디자인 제안을 통해 토지를 공급하는 조건부 형태의 토지공급 과정에서, 도시 및 건축 디자인 지침이 공모작품에 어떻게 적용되었는지를 분석함으로서, 도시 및 건축 디자인 지침을 통한 통합적인 도시디자인 가능성 검증을 목적으로 하고 있다. 이상의 분석결과 다음과 같은 결론을 얻었다. 첫째, 경관 및 매스관리를 위한 스카이라인(높이 및 층수), 통경축 및 필지별 형태 예시안은, 제시된 지침의 범위내에서 창의적 해석을 통해 다양한 건축적 아이디어가 제출되어 의미있는 도시경관 관리방법으로 판단된다. 둘째, 각 Zone별 디자인 주제 설정을 통한 장소만들기는 적절한 사례 이미지 예시를 통해 PA의 의도를 구현할 수 있었으며, 동시에 성능(수직동선 위치, 셋백 규격 등)에 기반 한 디자인 지침은 실현성이 높게 나타나고 있다. 셋째, 행정중심복합도시 1-5생활권 제안공모는 디자인 제안공모를 통해 상업용지를 판매하는 최초의 사례로서, 도시 및 장소디자인을 통해 공공성을 제고하는 ‘선계획-후판매’ 토지공급의 의미있는 사례로 판단된다. This study aims to verify the possibility of comprehensive urban design through urban and architecture design guidelines. It is done by analyzing how the guidelines were applied during conditioned land supplying process which the land is supplied through design proposals. The results are as follows : First, the skylines(height and story regulations) and view corridor guidelines are valid for silhouette control in architectural mass design. Second, place-making strategies via story-telling in each zone are worked well figuring out similar images and requirements based on performance(location for vertical movements, specs for set-back, etc). Third, Life-Zone 1-5 of Central Commercial Area, as the first case to sell commercial area through design proposal, is a significant ‘pre design-after selling’ case that it improves publicness through urban and place design.

이정수(Lee, Jeong-Soo),윤성훈(Yun, Sung-Hun),한정(Han, Jeong) 한국도시설계학회 2011 도시설계 : 한국도시설계학회지 Vol.12 No.6

최근 도시 경쟁력 강화를 위한 한 수단으로 도시정책 및 사업에서 적용되고 있는 도시디자인(경관계획 및 공공디자인 등)은 개념적 정의의 혼란과 체계적인 접근의 부재로 정책 및 사업 추진에 어려움을 겪고 있다. 이러한 배경으로부터 본 연구는 도시디자인(경관계획 및 공공디자인 등) 정책 및 사업추진의 체계적인 방법론 제시를 목적으로, 대전광역시를 사례로 도시디자인 추진전략 프로세스 모델을 분석 검토 하였다. 이를 위하여 첫째, 도시정체성 분석을 위하여 역사, 자연 및 인문환경 분석, 관련계획에 나타나는 도시정체성 분석 및 주민설문조사 등을 실시하여 ‘도시다움’을 도출하였다. 둘째, ‘도시다움’의 도시정체성 및 도시이미지 형성에 영향을 미치는 주요 요인을 분석하였다. 그리고 셋째, ‘도시다움’을 강화하는 도시디자인 기본구상, 추진전략프로 젝트 및 선도사업 추출 등의 과정을 제시하였다. 이러한 과정은 도시디자인(경관계획 및 공공디자인 등) 정책의 위계 및 사업추진의 프로세스 제안에 의미를 둘 수 있다. As a tool to promote competitiveness of a city, urban design has been widely employed in policy-making and its implement recently. Among its strategies is public design for landscaping and public facilities which have, however, struggled to be carried out due to unclear definition of urban design domain and lack of systematic approaches. This study aimed to propose a systematic methodology to develop strategies for urban design and policy. It analyzes a process model for urban design strategy revealed in Daejeon Metropolitan City as an example. It derives an image of ‘city-like’ - an identity derived from a city resident survey. Primary factors influencing the identity of ‘city-like’ and the formation of city image were analyzed. To promote ‘city-like’, framework for urban design well as process of strategic project were developed. These findings suggest a hierarchy of policy in urban design and procedures of project planning including landscaping and public facilities design.
