Architecture has been expressed a complexity of their civilization with evolving into a living spaces and a crystalloid of culture in the times. So, architecture is always a dramatic phenomenon related to architectural aesthetic and technical expression in harmony with social and cultural issues by the times. From this point of view, we can describe that architecture is one of an important mediators to analyze the integrated trend of time. Specially an expressed building envelop which is a matter of consequence in the architectural component is first visual factor including architectural meaning and historical back ground. Therefore, this study firstly starts an investment for discriminative characteristics of building envelop design in the times, then will take the comparative analysis related with modern age and contemporary age based on phases of the times. This research will give the chance to prepare of the pillar of future envelop design in the practical affairs and has simultaneously the chance to understand of inclusive envelop design methodology by the changes of the times.

제어이론의 역사적 발전사를 고찰해보면 1930년대부터 1960년대까지를 고전 제어(classical control) 시대로 분류되고 이때 주로 사용되었던 용어들은 주파수역(frequency domain)에서 사용된 개념인 극점(pole), 영점(zero), Nyquist, 근궤적(root-Locus) 선도(plot)등으로 대표된다. 그 다음단계인 현대 제어(modern control) 시대 (1960년대-1980년대)때는 새로운 개념들이 도입 되었는데 시간역(time domain)에서 사용되는 상태공간(state-space) 모델, 가제어성(controllability), 가관측성(observability), Kalman 필터, LQG 제어 등이다. 1980년대부터 현재까지를 강인제어(robust control) 시대로 분류하는데 이것의 특징들은 극점이나 영점 대신 상태공간 모델을 사용하여 주파수역에서 정의되는 개념들인 H$_{\infty}$ 합성법, .$\mu$ 해석법, LQG/LTR 및 QFT, Lyapunov 등으로 대표된다. 현대제어시대때는 제어기 K는 공칭 플랜트 모델 G$_{0}$를 기준으로 설계되었으나 실제로 공칭 플랜트 모델은 실제 플랜트와 항상 같을 수가 없었다. 따라서 실제 플랜트 G는 G=G$_{0}$ + .DELTA.G로 표현되며 여기서 .DELTA.G는 플랜트 불 확실성(plant uncertainty), 즉 실제 플랜트와 공칭 플랜트의 차이를 나타낸 다. 이 플랜트 불확실성은 제어기가 실제 응용되어 사용되었을 때 제대로 작동하지 않는 주요 이유중에 하나이다. 이와 같은 상황에서 안정도 강인성 (stability robustness) 및 성능 강인성(performance rosubtness)의 보장은 상 당히 중요한 문제로 대두되었으며 주어진 플랜트 불확실성하에서 이러한 강이성들이 보장되는 제어이론들 중 H$_{\infty}$ 제어이론이 많이 연구/응용 되고 있다. 특히 공칭 플랜트 모델과 함께 사용되는 플랜트 모델과 함께 사용되는 플랜트 불확실성 모델은 직접적으로 성능 및 안정도에 영향을 미치므로 주의 깊게 선정해야 한다.

The standing plaster figure entitled is an early work from Choi Man Lin's 'Eve' series. It reflects the aesthetics of abstract sculpture in the period following Korea's liberation from Japanese colonial rule. Modern and contemporary sculptures can be made from a wide variety of materials, so the particular selection of materials and expressive techniques are indicative of both the artist's intentions and the zeitgeist of the moment. In this regard, the materials and production techniques used in provide important basic data for the chronological study of Choi's artistic development. In this study, scientific analysis was conducted to reveal the production techniques used in the work. The scope of appropriate conservation treatment was decided through consultation between several people with decision-making authority. First, the internal structure was inspected using X-CT scanning, and a material analysis was conducted to identify the formal characteristics, materials, and production techniques found in the work. As the analyses revealed the work to be in a relatively stable state, only minimal conservation treatment was applied based on the opinions expressed by the institution housing the work, by a former assistant of the artist, and in an interview granted by the artist during his lifetime.

Since modernization period thru Japanese colonial era the modern architect began to play a important role for Korean housing architecture. So called 'House as an Art Work', detached houses by prominent architects, belong to a meaningful sector in Korean modern housing architecture. The harmony with tradition was always big issue for such works. This study aims to understand how paradigms for tradition were interpreted with the changes of the time. The analysis showed various tryout by architects, that concretize traditional characteristics in their work. For example, traditional lifestyle were clearly reflected in the floorplan during 30's and 40's. In the 70's building mass and formative roof design were emphasized to present traditional image. As well as it represented primitive esthetic and vernacular decoration. In addition, expressive tendency, that demonstrates korean sentiment through material and its texture, got a preference. Since latter half of 80's some traditional architectural elements were modernized and space characteristics were newly created from acculturation. Furthermore the philosophy of "Subdivision of building wings and Emptiness" follows this trend. This type made a courtyard and connected articulated building masses each other. "Sympathy with Nature" were most essential for a traditional houses in contrast with western architecture. Many architects today make various method to bring nature into interior space and to contemplate nature In the house. Such kinds of adaptation to tradition could be understood as a unique process to manifest identity of Korean modern houses.

Her Korean identity, which was formed through her Confucius upbringing as well as traditional value system of her family, had a strong presence in her work, and she remained a quintessential figure in Korea's female sijo poet circle for 30 years until her passing in 1976. Despite the highly acclaimed talent and her noble aspirations, it is undeniable that her works did not receive fair assessment due to her private life.

Seochon('West Village') is located in the west side of Gyeongbokgung(Gyeongbok Royal Palace) inside the old city wall of Seoul. Seochon has beautiful scenic view surrounding Mt. Inwang and has been known as the representative historical and cultural landscape region in Korea that historical and cultural resources are rich. But when the figure of Seochon which has repeated the changes with the ones of the times is considered, values of beauty of natural landscape that Seochon had and its own placeness have not been gradually recognized as it has been swept away in logic of the development on the strength of economics. This study tries to examine the original form of landscape on Seochon which can be the standard of landscape change, the causes and process of its change and possibility to conserve and restore it to recognize potential value about historical culture of Seochon landscape and conserve and protect it. For this, this study compared and analyzed literature including poems and Yusangi, paintings and names of the scenery of the seasons as the landscape texts with the current status. The study result has found that Pilwundae should rehabilitate cultural assets to secure the prospect right and protect neighboring bedrock, Suseong-dong should expand the restoration areas focusing on the projects to make parks which are now being restored, Cheonghwigak and Cheongpunggye areas should restore waterways including historicity which is connected to figures and Seshimdae and Baekun-dong green zone should set the protective area for conservation.

The historic cultural landscape of East lake in Kyung river area during Joseon dynasty was very outstanding that it had many attractions of scenic beauty, however, the Han river of today is being recognized as a natural landscape and as a place with low cultural and historical traits. This study applied landscape characteristics of the cultural space of Joseon Dynasty on visual image elements of Lynch to research the landscape characteristics. The research results are as follows. When East lake was applied to visual image elements, it was recognized as a 'superb' 'paths,' and the 'edge' which signifies the boundary showed its 'superb' clarity of the East lake. For the 'node,' a turning point of direction, Dumopo represented the 'superb' awareness. As East lake, Apgujung, and Jecheonjung represented the 'superb' awareness when 'landmark' among visual image elements of Lynch was applied to the cultural space, the awareness level and reputation were proportional to the visual image elements. When pattern, structure, and meaning of the cultural space were clear and had definite identity, the 'landmark' and 'district' elements were 'superb.' It was also identified that when awareness level of space was higher, the awareness of historic cultural landscape was high as well. Therefore, considering visual awareness level of the historic cultural landscape of Han river during restoration to investigate and to conduct case studies is considered to increase the awareness level of historicity and cultural character as well as restoration of the place.

The History and Culture Park and the Lee Kun-hee Donation Hall will be built in Songhyeon-dong, Seoul. Political games from the Joseon Dynasty to the present greatly influenced the historicity of Songhyeon-dong. However, place analysis was limited to changes in landowners and land uses rather than a historical context. Therefore, this study analyzed the context in which the placeness of Songhyeon-dong changed according to the emergence of cultural hegemony using the perspective of modern cultural geography and comparative history. As a result of the analysis, cultural hegemony in historical transitions, such as Sinocentrism, maritime expansion, civil revolutions, imperialism, nationalism, popular art, and neoliberalism, was found to have created new intellectuals in Bukchon, including Songhyeon-dong, and influenced social systems and spatial policies. In this social relations, the placeness of Songhyeon-dong changed as follows. First, the founding forces of Joseon created pine forests as Bibo Forests to invocate the permanence of the dynasty. In the late Joseon dynasty, it was an era of maritime expansion, and as Joseon's yeonhaeng increased, a garden for the Gyeonghwasejok, who enjoyed the culture of the Qing dynasty, was built. Although pine forests and gardens disappeared due to the development of housing complexes as the population soared during the Japanese colonial era, Cha Gyeong's landscape aesthetics, which harmonized artificial gardens and external nature, are worth reinterpreting in modern times. Second, the wave of modernization created a new school in Bukchon and a boarding house in Songhyeon-dong owned by a pro-Japanese faction. Angukdongcheon-gil, next to Songhyeon-dong, was where thinkers who promoted civil revolution and national self-determination exchanged ideas. Songhyeon-dong, the largest boarding house, served as a residence for students to participate in the March 1st Movement and was the cradle of the resulting culture of student movements. The appearance of the old road is preserved, so it is a significant part of the regeneration of walking in the historic city center, connecting Gwanghwamun-Bukchon-Insadong -Donhwamunro. Third, from the cultural rule of the Government General of Joseon to the Military Government, Songhyeon-dong acted as a passage to western culture with the Joseon Siksan Bank's cultural housing and staff accommodations at the U.S. Embassy. Ancient and contemporary art coexisted in the surrounding area, so the modern and contemporary art market was formed. The Lee Kun-hee Donation Hall is expected to form a cultural belt for citizens with the gallery, Bukchon Hanok Village, the Craft Museum, and the Modern Museum of Art. Discourses and challenges are needed to recreate the place in harmony with the forests, gardens, the street of citizens' birth, history and culture park, the art museum, and the surrounding walking network.

Gwonwu Hong Chan-yu is one of the modern and contemporary Korean scholars of Sino-Korean literature and one of the literati of his era, so is respected as a guiding light by academic descendants. Gwonwu was a teacher of his era, who experienced all the turbulence of Korean society, such as the Japanese occupation by force, the Korean War, the military dictatorship, and the struggle for democracy, and who educated and led young scholars of his time. However, academia has not payed attention to his life and achievements since his death. This paper is to examine the poetry of Gwonwu Hong Chan-yu, one of the representative modern and contemporary scholar of Sini-Korean literature, which has not yet been discussed by academia. The minimal meaning of this paper is that it is a first work based on his anthology, which has not been discussed by academia, and a first full-scale study on Gwonwu Hongchan-yu. For the reason, this paper aims at the detailed inspection of his poetic pieces recorded in his anthology. Nonetheless, despite such intentions, some limits cannot be avoided here and there in this paper for the insufficient knowledge and academic capability of this paper's writer and for the lack of academic sources. Gwonwu's poetry examined through his anthology shows the characteristic which is that his poems focus on exposing his own internal emotions. Such a characteristic says that his idea of poetic literature payed attention more to individuality, that is exposition of private emotions, than to social utility of poems. Gwonwu's such an idea of poetic literature can be generally affirmed throughout his poetry. Accordingly, Gwonwu preferred classical Chinese poems to archaistic poems, and single poems to serial poems; and avoided writing poems within social relations such as farewell-poems, bestowal-poems, and mourning-poems. When the characteristics of Gwonwu's poetic literature get summarized as such, however, some questions remain. The preferential question is whether the poems in his anthology are the whole poetry of him. Although Gwonwu's poetic pieces that the writer of this paper have checked out till now are all in his anthology, it is very much questionable whether Gwonwu's poetry can be summed up only with these poems. The next question is what is the writing method for taking joy(spice), sentiment, and full-heart into his poems if Gwonwu's poems focus on exposing his internal emotions, and if poems exposing joy and poems exposing sentiment and full-heart appear coherently in various different spaces and circumstances of writing. The final question is what are the meanings of Gwonwu's poems if his poetry checked out through his anthology directly shows either the reality carried in his poems or the reality of a time in his life. The questions listed above are thought to be resolved by the synchronizing process of stereoscopic searches both for Gwonwu as an individual and for the era of his life. Especially, spurring deeper researches toward a new direction regarding Gwonwu's poetry has an important meaning for construction of a complete modern and contemporary history of Sino-Korean literature and for procurement of continuous research on Sino-Korean literature and its history. For the reason, it is thought that more efforts of researchers are required.
