This study is the result of a design proposal to create a history and culture complex for the "Gungjip," an Important Folklore Cultural Heritage, and its surroundings located in Namyangju, Gyeonggi Province. In particular, the purpose is to introduce a new design approach to a historical and cultural complex consisting of the Gungjip House and Hanok annexes to be opened to the public in the future; and to provide its implications for future study. Although the architectural condition of Gungjip House is well preserved, several problems have been found in the use of the site as a public space due to the lack of a plan for systematic space experience, lack of specific spatial programs, and the too much shade due to uncontrolled green areas, etc. Therefore, the plan presented in this study largely sought to respect the meaning of historical landscape as a public space and to balance with the contemporary needs. The design strategies derived through basic research are to strengthen the sense of place as a cultural heritage; to respect the ecological characteristics of the site and visual harmony with the surrounding environment; and to suggest spatial programs suitable for the contemporary needs. Based on these strategies, the framework for the entire space is conceptually composed of four spaces; Oewon, Ganjeong, Jujeong, and Huwon, and proposes systematical land use and landscape experience. The main feature of this plan is the landscape approach, which aims to preserve the architectural cultural assets in their original form, but to create a reasonable land use and meaningful landscape experience based on the sense of place.

Considering that the weight of a biaxial hollow slab system is not increased with an incremental increase in its thickness, and that the flexural stiffness of a biaxial hollow slab is not significantly lower than that of a general solid slab, there has been a growing need for biaxial hollow slab systems, because long span structures are in great demand. In a long span structure, the problem of vibration of floor slabs frequently occurs, and the dynamic characteristics of a biaxial hollow slab system are quite different from the conventional floor systems. Therefore, in this study, the floor vibration of a biaxial hollow slab system subjected to walking load is investigated in comparison with a conventional floor slab system. For the efficiency of time history analysis, an equivalent plate slab model that can precisely represent the dynamic behavior of a biaxial hollow slab system is used. From the analytical results, it was determined that vibration of a biaxial hollow slab system subjected to walking load is evaluated as "office-level vibration," according to the classifications of the architectural institute of Japan and ANSI.

This study aimed to interpret aesthetic properties of post-industrial parks with a perspective of the sublime. It examined the roles of the sublime related to landscape architectural history and traced aesthetic characteristics of post-industrial parks based on aesthetic issues of the sublime. In the history of landscape architecture, the sublime had expanded the scope of aesthetic enjoyment. It had operated as an alternative aesthetic category against conventional landscape design. At the same time, it had been associated with the original role of landscape architecture, which created artworks by taming wild and terrible qualities of wilderness or brown field. This study discovered sublime characteristics of post-industrial parks, inquiring into the relationship between the aged industrial infrastructures and wild plants. First, the sense of industrial structure and the sense of plants have conflict dialectically, constructing an aesthetic field of unique sensory experiences. Second, the dialectical relationship produced an uncertainty in time so that people can experience the complexity of time. Third, post-industrial parks proposed an alternative view of nature. Post-industrial parks presented healing power to restore contaminated land through ecological design strategy so that people can find the quality of wilderness in the brown field of urban landscape. As a result, an aesthetic experience of post-industrial parks produced a sublime impression.

The objective of this study was to experimentally investigate the effect of heat curing methods on the temperature history and strength development of slab concrete exposed to $-10^{\circ}C$. The goal was to determine proper heat curing methods for the protection of nuclear power plant structures against early-age frost damage under adverse (cold) conditions. Two types of methods were studied: heat insulation alone and in combination with a heating cable. For heat curing with heat insulation alone, either sawdust or a double layer bubble sheet (2-BS) was applied. For curing with a combination of heat insulation and a heating cable, an embedded heating cable was used with either a sawdust cover, a 2-BS cover, or a quadruple layer bubble sheet (4-BS) cover. Seven different slab specimens with dimensions of $1200{\times}600{\times}200$ mm and a design strength of 27 MPa were fabricated and cured at $-10^{\circ}C$ for 7 d. The application of sawdust and 2-BS allowed the concrete temperature to fall below $0^{\circ}C$ within 40 h after exposure to $-10^{\circ}C$, and then, the temperature dropped to $-10^{\circ}C$ and remained there for 7 d owing to insufficient thermal resistance. However, the combination of a heating cable plus sawdust or 2-BS maintained the concrete temperature around $5^{\circ}C$ for 7 d. Moreover, the combination of the heating cable and 4-BS maintained the concrete temperature around $10^{\circ}C$ for 7 d. This was due to the continuous heat supply from the heating cable and the prevention of heat loss by the 4-BS. For maturity development, which is an index of early-age frost damage, the application of heat insulation materials alone did not allow the concrete to meet the minimum maturity required to protect against early-age frost damage after 7 d, owing to poor thermal resistance. However, the combination of the heating cable and the heat insulating materials allowed the concrete to attain the minimum maturity level after just 3 d. In the case of strength development, the heat insulation materials alone were insufficient to achieve the minimum 7-d strength required to prevent early-age frost damage. However, the combination of a heating cable and heat insulating materials met both the minimum 7-d strength and the 28-d design strength owing to the heat supply and thermal resistance. Therefore, it is believed that by combining a heating cable and 4-BS, concrete exposed to $-10^{\circ}C$ can be effectively protected from early-age frost damage and can attain the required 28-d compressive strength.

Concrete exposed to severely low temperature below $-20^{\circ}C$ should be provided with proper heat supplying curing to protect the concrete from early frost damage at the time of pouring.meanwhile, so far, effective heat curingmethods of the concrete under severely low temperature are not well established in Korea. For this reason, the objective of this paper is to provide effective heat curingmethod of concrete exposed to severely low temperature to protect early frost damage by varying the combination of heat curingmaterial combinations. Temperature history,maturity development and core strength results are investigated. Fourmock-up specimens simulating slab, wall and column were prepared and heat insulation, heat supplying and both were applied. Test results indicate that the combination of quadruple layer bubble sheet(4BS) and embedding of heating cable has desirable performance for a slab, and heat supplying curing inside heat enclosure and heat generationmat also shows desirable performance for a wall, and for a column, use of EPS heat insulation has proper performance against early frost damage, which reaches $45^{\circ}D{\cdot}D$ and helps the concretemaintain above $0^{\circ}C$ within 3 days. Themethodsmentioned above are believed to be optimum protection from early frost damage of the concrete under $-20^{\circ}C$.

This research sought to examine the strategies of cultural heritage proving the negative history to be registered as world heritage, among the World Heritages registered in UNESCO. Therefore, to comprehend "negative history"and the heritages with "instructive value," the new term of "Remembrance Heritage"was suggested, and such cases of world heritage were analyzed. Especially by analyzing the criteria of being registered by focusing on the cases of similar World Heritages with similar historical background or form as Korean DMZ, the criteria of OUV that may be applied when Korean DMZ is promoted to be registered as World Heritage. The research results may be summarized as the following. First of all, Remembrance Heritage is a place in which events of universal significance have occurred, rather than the historical, artistic, landscape, and scholastic value of the heritage itself, and was evaluated as architecture, landscape, or place in which the events or historical steps could be verified through architectural, landscape, archaeological or technical means. Secondly, Remembrance Heritage was often applied to be registered with the criterion (vi), and criterion (iii) or criterion (iv). Thirdly, in case of the Korean DMZ, application of criterion (iv) as heritage proving the age of cold war and criterion (vi) as symbolic value of peace may be possible.

A museum architecture has been developed as important representation of a specific period in architectural history. Modern concept of museum architecture has started by Karl Fredrich van Schinkel(1781-1841) through das Altes Museum(1823-1830) back in early 20th century and it continues to be the model for museum architecture for over 30 years. By middle of the 20th century, the movement of redefining new model for the new era on the subject of museum architecture was developed. This development was lead by the three masters of the modern architecture at the time. F.L. Wright, Corbusier, Mies and they were responsible and very active in creating new concepts. Their works in museum design became the prototype and they tried hard to make sure their new concepts to be the stepping stone for further development. This study is to compare the three different museums designed by those masters of the modern architecture, particularly on the issue of the exhibition spaces. The purpose of the study will be focused on the point of interior architecture such as the matters of layout and design characteristics of the exhibition spaces. And it will reveal the impact made by those masters on the advanced development of the current generations of museum designers as well as to describe the prototype of exhibition space. The analyzation was done on FLW's Guggenheim Museum in New York, Corbusier's the National Museum of Western Art in Tokyo, and Mies' Die Neue National Galerie in Berliv. Comparable materials were collected through site visits and reference documents from various publications. It will be ideal if this study can be used for further development in new museum design in this country.

The results of examining the architectural features and changes of the main building of Dogapsa temple which is multi roofs wooden structure are as follows. The passage comparing 'Dogapsa' of <>, account of Lee Ha Gon's trip as the literature showing the appearance of Dogapsa temple in the early 18th century to Borimsa through verse of 'Dutacho' was noticeable. Dogapsa temple at Yeongam was distant over 100 ri from Borimsa temple at Jangheung and it was considered that there were many temples at Mt. Wolchul, Yeongam and there were also many temples to be comparable with it. But, Dogapsa temple was compared to Borimsa temple because verses 'many-storied building is high and immense' of 'Dogapsa' at <> and 'Dogapsa is lower than Borimsa at Jangheung' at 'Dutacho' of <> were interpreted as the existence of multi roofs Buddhist temple which had something in common with Dogapsa and Borimsa and was comparable to them. According to existing materials, it was assumed that the main building of Dogapsa was burnt through the Japanese invasion of Korea in the 52nd year of the sexagenary cycle (Eulmyooebyeon, 1555) and Jungyujaeran (1597), but record of major history of the main buildings of Dogapsa and Borimsa indicated that multi roofs wooden structure of the two temples were built at the same period. Since multi roofs wooden structure of main building of Borimsa was rebuilt in 1692, these buildings existed from the early 18th century to middle 18th century.

A park will soon be developed in an area of Gwangjang-dong, Gwangjin-gu. The place has been a patch of green space for years, isolated by driveways and apartment complexes and abandoned. This article describes plans to infuse the abandoned green space with history, ecology, culture, and sports. The facilities that are to be constructed in and around the green space are positioned to take into account the path of the sun and the location of the curvilinear green space axis. The cultural space is planned as a centerpiece of the park, linked with the sports facilities. The overall framework is arranged in harmony with nearby elementary schools, parks, public facilities, athletic facilities, parking lots, and apartment complexes. The themed circulation route was constructed according to the environmental conditions and the spatial plan. In addition, the historical space is planned to work in close conjunction with the cultural space, and the streets and pedestrian pathways have characters of their own. The established contour lines will be carefully preserved, and an ecological pond will. The facilities, such as the outdoor performance stage, the outdoor art gallery, the Monument of Wind represented by a sail, and the pedestrian bridge in memory of Acha-sansung, are positioned for spatial balance and to provide a nexus. The bamboo forest, designed to foster the experience of sound effects, the architectural thematic plants, and the ecological pond are positioned to connect to each other around the greenspace axis. The main facilities are the outdoor theater, the bamboo forest, the Acha-sansung bridge, the Monument of Wind, the ecological pond, the four-season flower garden, parking lots, playgrounds, circulatory athletic pathways, and the tennis court.

According to the Samkuk Saki(History of Three Nations), An-ap pond was constructed in the 14th year of the reign of King Mun-$\mu$ But this period precedes the unification of Shilla(in the 16th year the reign of king Mun-mu) and Shilla was at war. Therefore I suppose the 16th year of the King's reign is just the time of the commencement of the construction of the pond. But the real construction had not been started before the 16th year of the King's reign, after the unification of the three nations into Shilla Dynasty. Another record of making a larger pond(the 19th year of the reign of king Kyung-duk) may signify the enlargement of the very pond that had been built the 16th year of King Mun-mu's reign. Korean traditional belief was the belief in the Dragon, the Mountain God, and the Heavenly God and these was deeply rooted in the Royal family and perhaps had influenced the building of An-ap pond. Namely it is explained that Em-hae Jun sympolizes the An-ap pond itself as the sea and the Dragon lived in the sea and also the mountain built in the East bank of An-ap pond is related to the Mountain God. And also Taoism's Sin Sun Sa-Sang(Paradise philosophy) had influenced the building of the three legendary immortal islands, called Yong Ju, Bang-Jang, Bong-Rae in the An-ap pond. It is supposed that the age of An-ap pond from the above mentioned facts and inferences and we can also understand the influence of the Royal family customs on the building of An-ap pond. The inscriptions on the vessels and architectural accessories suggest us the influence of the Royal family customs on the construction of An-ap pond.
