The study on shilla monumental inscription has been accomplished by many historians. However, the research on segmentation of monumental inscription image using digital image processing is not sufficient for restoration of the image. Although, many image processing methods have been proposed for region extraction in still image, there is no suitable method for accurate interpretation of monumental inscription image. To distinguish foreground and background region in the image, this paper presents new segmentation algorithm composed of contrast adjustment and median filtering, thresholding and sobel operation, as pre-processing and post-processing. The result show that background and foreground regions are segmented in monumental inscription image.

The study on shilla monumental inscription has been accomplished by many historians. However, the research on segmentation of monumental inscription image using digital image processing technique is not sufficient. The preprocessing using computer is needed for accurate interpretation of history. In this paper, A morphological filtering using directional information is presented. Directional filtering is effective in reducing noises and preserving edges. The opening and closing operations in the 1st stage are performed for the pixel is aligned to the vertical, horizontal and two diagonal directions. The Opening operation supresses the positive impulse noise while the closing operation the negative ones. Then Directional filter and post-processing are applied to the image. Experimental result shows outstanding performance for interpretation.

This research has been done based on the Jeon Si Gwa(田柴科) regulation, the monumental inscription material and the former studies. The background of adapting the official uniform regulation in the early Goryeo Dynasty has been surveyed. Differentiating criterion in the official uniform color like purple(紫衫), red(丹衫), red(緋衫), and green(綠衫) has been studied. The official rank had been classified by the color of the official uniform in the early Goryeo uniform regulation. The lower class had worn purple(紫衫). The purple wearing class had not been the government post but the official rank. Those who worked for the Palace had worn purple color since purple color represented the Imperial Palace on which TAI-IL(太一), that is, the highest one of gods dwelt. Those who had worn red(丹色) in the monumental inscription had worked for the job associated with the military service or Hanlim savant(翰林學士) of Kwangmun Academy(光文院) and Hanlim Academy(翰林元). Dan Seo(丹書) which recorded King's commands also means the monumental inscription. In the Goryeosa(高麗史), the military class had been only in Dan Sam(丹衫). That means those class worn Dan Sam(丹衫) could have been as the strong supportive class for the Dynasty. In the early Goryeo Dynasty, the four colored uniform regulation had followed the enforcing policy of the royal authority. It has been assumed that the uniform regulation had been used as a way of enrolling the new supporting class into the existing official system. Dan Sam(丹衫) which had been worn only in the early Goryeo can be seen as the special class for strengthening the royal authority.

Seismic assessment and rehabilitation of Monumental Buildings constitute an important issue in many regions around the world to preserve cultural heritage. On the contrary, many recent earthquakes have demonstrated the high vulnerability of this type of structures. The high nonlinear masonry behaviour requires ad hoc refined finite element numerical models, whose complexity and computational costs are generally unsuitable for practical applications. For these reasons, several authors proposed simplified numerical strategies to be used in engineering practice. However, most of these alternative methods are oversimplified being based on the assumption of in-plane behaviour of masonry walls. Moreover, they cannot be used for modelling the monumental structures for which the interaction between plane and out-plane behaviour governs the structural response. Recently, an innovative discrete-modelling approach for the simulation of both in-plane and out of-plane response of masonry structures was proposed and applied to study several typologies of historic structures. In this paper the latter model is applied with reference to a real case study, and numerically compared with an advanced finite element modelling. The method is applied to the St.Venerio church in Reggiolo (Italy), damaged during the 2012 Emilia-Romagna earthquake and numerically investigated in the literature.

Considering on the crisis and dilemma of monumentality in Modern architecture, this study analyse the historic reason of decay and new possibility of monumentality within the context of contemporary socio-cultural context. Historically monumentality has been considered as a main substance of High architecture in e tradition of Western Architecture. Difference between building and architecture mainly lies in monumentality which brings about esthetic quality. Usually architects take it granted that the physical and formal characteristics automatically cause the monumentality, But since the modem period the decline of communicative and representative function of architecture made this belief questionable. As Monumentality itself faced the dilemma with the modernity, ironically architects has to response to the task to handle the increasing social demands of monumental building. This study firstly shows the dilemma of monumentality in depth in case of the holocaust museum. Then we analyse the concept of monumentality itself by means of theoretical view of A. Loos and A Riegl We also analyse the change of role which monumental building played in history. Cultural and social change of context, and fundamental change of architecture old way of building a monument impossible. In conclusion this study proposes the new concept and searches new horizon of monumentality with a finding of the otherness of monumentality. Conventional monumental building language has to give way to new approaches. With some examples we already can find a new possibility.

This paper outlines the current steel design climate and describes some recent and unusual designs using structural steel or composite steel and concrete which have been carried out in Hong Kong and the East Asia region. Composite structural systems for very tall buildings are outlined. A case study of concept designs for one of these is presented. Two further case studies are presented: a refurbishment project where the use of steel and innovative strengthening techniques allowed an additional five stories to be built on an existing reinforced concrete frame and a monumental sculpture.

This study was conducted to formulate management guidelines for monumental old trees in Korea through analysis of growing environments. A total of 20 old trees designated as natural monuments in Seoul, Incheon, and Gyeonggi provinces were surveyed for biological characteristics, surrounding environments, root collar conditions, tree health, and soil characteristics. Relationships among root collar conditions, tree health, and soil characteristics were analyzed by correlation. The old solitary trees designated as natural monuments included Pinus bungeana(4 trees), Juniperus chinensis(3 trees), Ginkgo biloba(3 trees), Poncirus trifoliata(2 trees), Actinidia arguta, Wisteria floribunda, Thuja orientalis, Quercus variabilis, Sophora japonica, Fraxinus rhynchophylla, Zelkova serrata, and Pinus densiflora. The tree height ranged from 3.56 to 67m, and root collar diameter ranged from 1.01 to 15.2m. The monumental old trees were growing on the various sites ranging from gardens, historical sites, open agricultural fields, mountain hills, to near the ocean beaches and streams. The coverage of bald land ranged from 50 to 100%, and depth of filled soil around the root collar ranged from 0 to 50cm. Tree health was expressed as the amount of branch dieback, cavity development, detachment of cambial tissue, infliction by diseases and insects. The branch dieback ranged from 5 to 20%, cavity development ranged from 10 to 100$cm^3$, detachment of cambial tissue ranged from 5 to 45%, and infliction by diseases and insects ranged from 5 to 20%. Soil pH ranged from 5.9 to 8.3, organic matter contents from 12 to 56%, phosphorus contents from 104 to 618ppm, while soil compaction ranged from 7 to 28mm. Results of correlation analysis showed that coverage of bald land was the most serious factor to deteriorate the cavity development and detachment of cambial tissue. In addition, chemical properties of soils seemed to be related to the health of the trees.

본 논문은 조선 초 중기, 조선후기, 대한제국기 세 시기로 나누어 조선왕릉에 건립된 신도비와 표석의 시기별 건립추이와 양식적 특징에 대해 살펴본 것이다. 그 결과 왕실 능비(신도비와 표석)는 일반 사대부가와 달리 건립한 시기와 주체, 후계왕의 의도에 따라 시기별 차이를 보이며 제작되었음을 알 수 있었다. 구체적으로 15~17세기는 왕릉 신도비의 건립과 재건이 이루어진 시기, 18세기는 신도비가 표석으로 대치되어 다수 건립되었고 국왕의 어필을 직접 돌에 새긴 어필비가 처음으로 등장한 시기이며 대한제국기는 황제국으로 격상됨에 따라 조선 개국자인 태조와 왕후, 선조들에 대한 추숭(追崇) 사업이 활발해지면서 표석 중건이 이루어진 시기로 요약할 수 있다. 이러한 결과를 토대로 본다면, 결국 우리나라 능비의 역사는 조선후기를 기점으로 형성된 것이라고 해도 큰 무리가 없을 것이다. 왕릉 신도비의 형식은 삼국시대의 부정형한 석비의 초보적인 형태에서 벗어나'귀부이수'형의 당비(唐碑) 형식을 수용한 통일신라시대를 거쳐 고려 말 탑비의 퇴화된 양식에서 기원을 찾아볼 수 있다. 15세기 건립 당시부터 선왕에 대한 숭모 예를 표현하고자 하는 국왕과 왕의 치적이 국사(國史)에 모두 기록되어 있으므로 신도비를 별도로 세울 필요가 없다는 신료들의 입장이 대치되면서 건원릉 제릉 헌릉 구 영릉 4곳에만 건립된 채 왕릉에는 한동안 석비가 건립되지 않았다. 신도비 건립이 중단된 이후 17세기에 이르러 왕릉에 아무런 표(表)를 해 둘 수 없다는 의견이 제기됨에 따라 형식이 간소한 표석이 건립되기 시작했으며, 1682년 작 영릉(寧陵)의 표석은 최초로 왕릉에 건립된 표석이자 장대한 규모, 섬세한 조각기법을 보여주는 의미 있는 작품이라고 할 수 있다. 왕릉의 능표는 영조 재위 기간인 1740년대부터 대규모로 건립되었다. 열성(列聖)에 대한 추숭과 어필간행 등을 통해 자신의 왕위 계승의 전통성을 공표하고자 했던 영조는 제릉의 신도비를 재건하는 한편, 의릉(懿陵)을 비롯하여 총 20곳에 달하는 곳에 표석을 세우는 역사(役事)를 추진했고, 처음 친필 글씨를 돌에 새긴 어필비를 제작하기에 이르렀다. 이 시기 어필비 제작 현상은 임진왜란과 병자호란 후 소실된 어필을 보존하려 한 숙종의 신념을 계승한 영조에 의해 제도적으로 추진되면서 어필을 새긴 능비가 등장한 배경과 밀접한 연관이 있기 때문에 시대사적으로 주목할만하다. 이러한 표석은 1897년 고종이 대한제국을 선포하면서 다시 한번 다량 제작된 시기를 맞이하게 된다. 특히 고종은 대한제국의 정통성을 태조의 조선 건국에 두고 태조와 그 4대 선조에 대한 추숭과 기념물 제작에 심혈을 기울였고 전면과 후면 모두 자신의 글씨로 채움으로써 역대 어느 왕보다 통치자로서 권한을 상징적으로 드러내었다. 이상 언급한 왕릉의 신도비와 표석의 건립 추이는 동시대 원 묘에 건립된 신도비, 표석과 비교 고찰을 통해 시대별 특징과 왕실 조각품으로서 성격이 더욱 명확하게 드러날 것으로 생각한다.

The purpose of this study is to analyze the stress variation according to Hitler's residence using EEG data. Hitler's residence, one of the most monumental buildings, is designed as a grand and overbearing space, giving the visitor a sense of psychological pressure when moving from a high space to low space. Based on the above background, this paper constructs Hitler's residence using virtual reality and measure the changes of the beta waves which are known to be related with stress when the floor level moves from high to low space in Hitler's residence built in virtual space. The results of the experiment are as follows; when moving from high to low space, the subjects' stress was high and at the same time brain waves variation was increased greatly due to changes in space.
