This study examines the restoration project of Sokkuram, and introduces its preliminary plans by the architect Pai Ki Hyung. The restoration project started in 1958 with an inquiry committee of the restoration project, and was completed in 1964. Despite having undergone extensive repair work under Japanese supervision from 1913 and 1923, the repair work caused water leakages inside Sokkuram, and regular cleaning work that began in 1933 caused a lot of damage to the sculpture. In result of the surveys, the top priority of this project was to protect the sculptures inside Sokkuram by improving the environment of the cave. At that time, the architect Mr. Pai participated as a head of the fourth field surveyors to plan the restoration project and to design the preliminary plans. He proposed the installation of a double dome structure to prevent further water leakages on the concrete addition that was built up around the grotto by the Japanese. However, in 1961, the Cultural Heritage Committee of Korea examined the plans of Mr. Pai and immediately rejected them. The factors of the rejection were the omitting of entrance design, system of new double dome structure that presses the existing structure, and these changes that had to be made outside of the drainage plans. The repair work of Sokkuram began in 1961, and the main construction was building double dome structure and entrance installation. In this we realize that Mr. Pai's double dome structure plans were very important key concept of this project. This study attempts to demonstrate the double dome installations that Mr. Pai initially proposed, which ultimately remains as emblematic factors of Sokkuram's legacy.

The purpose of this study is to get a more fundamental definition of the term Architecture and Geonchuk through analyzing the origin and reception of the terminus technicus Architektonike. In Latin world the greek term Architektonike was adopted and replaced the term Constructio by Vitruvius and has played a significant role in the history of architecture. In the late 19th Century however, the word Architecture was translated into Geonchuk(建築) and has been dominantly used in countries such as Korea, Japan, and China. But the difference of the denotation between them has not yet been fully evaluated. The term Geonchuk signifies much the same as the Tektonik and remains as such in the architectural discourse. In this context, this study goes back to refer to the philosophy of Metaphysics by Aristotle. In his book the term Architektonike was defined for the first time as terminus technicus, and the philosophies in later Ages of Leibniz or of Kant adopted it to signify the world view in accordance with the time. However, the original thought of the Architektonike disappeared in architectural practice and has been used in most cases as a substitute for Oikodomike which denotes house-building. The usage of this word in later time shows that it lost its foundation to be interpreted not only in terms of principium cognoscendi, but also in terms of principium reale. From this the literal usage of the term architecture and Geonchuk has seldom to do with its original meaning and denotation of Architektonike and also they lost the status of terminus technicus for the discourse of arche which encompasses the meaning of both principle and universal order.

Old age is often compared as climbing mountains which requires walking out of breath, yet with wider vision. And it is also likened to the estuary where the river flows slowly and broadly into the open sea. Socially, old age has been regarded as a symbol of wisdom and reflection, and elderly people often take the role of sage who leads the community. On the other hand, the dementia, gray hair and wrinkles of old age were sometimes perceived as the decline of intellect and vitality. Especially, in the digital age in which technology makes people more sensitive to physical artificiality, the evaluation of the old age becomes more complex and obscure. In other words, some elderly people can not escape from Confucious convention of the elders first, which causes the denouncement by younger generations. On the other hand, some elderly people are becoming more adaptable to the trend of young people, emerging as the new elderly people. The anti-aging movement, early adaptation of IT, bioengineering regimen also strong for the advanced age. However, as the new elderly people are active in many fields of society, they also face intergenerational conflicts in some areas where remains the overlap between young people and them due to the limited openings in economy and culture. This study is a transdisciplinary research which can be called old age humanities. First of all, this paper looks at the aspects of lifestyles and intergeneration conflicts in old age in four Korean and Western literary works about the old people, and also searches how to improve the quality of the later life of old people, Overall, this paper aims to explore the way the old people can achieve the full life with the help of intergenerational dependency through building aging humanities and new communities for old people.

The purpose of this study is to review the research on Gangbang Palace and to presume the location of the palace through the study of feng shui. when the Mongols invaded, Ganghwado was the capital, moved from Gaegyeong and it was maintained for 39 years. At that time, the palace construction followed the palace of Gaegyeong, and the names such as Gujeong毬庭, Palace, and Sasa寺社 were the same as those of Gaegyeong. However, despite several archaeological excavations at Goryeo Palace Site, Historic Site No. 133, no actual remains of the Goryeo period were found. After the negative opinions on the current Goryeo Palace site became public, there have been several previous studies on the estimation of the location of the Goryeo Palace Site, and although there have been achievements, the location of the Goryeo Palace is still not confirmed. The key to presuming the location of the GangdoPalace江都宮闕 is first, whether the palace was located in the south of Songaksan, and second, at what point it was located in the south of Songaksan. As to whether the palace was located in the south of Songaksan, it was presumed that the Chiso治所 of Ganghwabu was located in Gukhwari, referring to the record in 『Shinjeungdongguknyeojiseungnam新增東國輿地勝覽』 that Goryeosan, a guardian mountain鎭山, was 'five ri west of Bu府西五里'. Accordingly, the location of the palace of 'Budongsimni 府東十里' in the old literature was estimated to be south of Songaksan Mountain. Also, the location of the palace on the south side of Songaksan was approached from a feng shui theory. Three places for the palace to be located are presumed to be 'Ganghwa Girls' High School', 'Seonggwang Church', or 'Above the Ganghwa-gun library', and the central axis of the palace is estimated to be 'Above the Ganghwa-gun library' where the corridor-type building relics were found among them, and the other two areas were presumed to be other buildings within the palace.

This study is initiated after discovering that Minsu, a man about 600 years ago, mentioned a new architectural type called 'Pan-ock' in a record he left when he was punished for slavery at Jeju. Although there are no additional records or architectural remains, the following two hypotheses were made regarding the existential possibility of Pan-ock. First, Pan-ock was originated from materials obtained from ships. Second, it was related to the Pan-ock-seon. The hypotheses are based on the premise that large wooden ships such as trade ships were being actively built, as it was 160 years before Chullyuk Geumjiryeon of king Injo was banned, and the woodworking skills were considerable. Another hypothesis is also established by comparing the records of Pan-ock with other records of the same period and inferring the relationship of related events. This study can serve as a basis for explaining the diversity of our architecture to overcome that most of the architecture have been lost compared to Korea's splendid history. Therefore, a sequent study intends to compare the hypotheses proposed after this study with the architecture in the coastal and island regions of the Korean Peninsula, in order to find and verify the authentic cases of Pan-ock in Korea and East Asia.

A new type of private education institute appeared starting from the 16^th century, called Seowon consist of educational spaces and Jesa(a form of memorial ritual for the family's ancestors) space. Seowon Architecture is representative Confucian Architecture. Seowon is a kind of private school and it is a higher educational institute. the time of establishment was from the middle of 16^th century to the end of 19^th century, but the famous Seowon which remains up to now had been mainly built from the end of 16^th century to the beginning of 17^th century. Seowon was built on a quiet place far from the town for Students and Scholars to concentrate on their study. and it has beautiful surrounding scenery. Seowon has a place for study in the front and a place for sacrifice at the back regardless of configuration of ground. Gangdang is a building in the place for study in which teacher and students study. It is smilar place to Myongryundang of Hyanggyo. As a plan composition, there is a wide Daechong and two rooms at the both sides. Infront of Cangdang, there are Dongjae and Seojae on the right and the left side which are student' dormitory. This study argues that the Confucianist ideas and topography are the factors that determine the hierarchy Seowon. In light of this, A Study on Spatial Configuration of Education Area in Do-dong Sewon attempted to conduct an analysis by applying such backgrounds, and therefore studied the arrangement rules and construction methods for Seowons.

In this study, we investigate the use of a negative stiffness tuned inerter damper system to improve the performance of a base-isolated structure. The negative stiffness tuned inerter damper system consists of a tuned inerter damper connected in parallel with a negative stiffness element. To find the optimal parameters for the base-isolated structure with negative stiffness tuned inerter damper system, we develop an optimization method based on performance criteria. The objective of the optimization is to minimize the superstructure acceleration response ratio, while ensuring that the base displacement response ratio remains below a specified target value. We evaluate the proposed method by conducting numerical analyses on an eight-story building. The structure is modeled using both a simplified 3-degree-of-freedom system and a more detailed story-by-story shear-beam model. Lastly, a comparative analysis using time history analysis is performed to compare the performance of the base-isolated structure with negative stiffness tuned inerter damper system with that of the base-isolated structure and base-isolated structure with tuned inerter damper systems. The results obtained from the comparative analysis show that the negative stiffness tuned inerter damper system outperforms the tuned inerter damper system in reducing the dynamic seismic response of the base-isolated structure. Overall, this study demonstrates that the negative stiffness tuned inerter damper system can effectively enhance the performance of base-isolated structures, providing improved seismic response reduction compared to other systems.

The hydration process of Controlled Low Strength Material (CLSM) used for backfill is the primary factor to determine the construction period. The objective of this study is to monitor the hydration process of CLSM using the Time Domain Reflectometry (TDR) and to establish the relationship between dielectric constant and compressive strength. The CLSM specimen is composed of cement, flyash, silt, sand, accelerator, and water. The material characteristics of the CLSM including flow, unit weight, compressive strength are investigated. To measure the dielectric constant of the CLSM during the curing time, TDR probe incorporated with a mold and a reflectometer are used. Experimental results show that the dielectric constant remains constant at early stage, and then decreases as the curing time increases. In addition, the dielectric constant is related to the compressive strength in inverse power function. This paper suggests that the TDR technique may be used as a non-destructive testing method in order to estimate the compressive strength of the CLSM mixture under construction.

Much has been made of the changes over time to apartment complexes during the era of rapid development in Korea. This study aimed at analyzing the chronological changes since the 1970s in the laws and regulations governing outdoor space and the residents' appreciation of outdoor space in Daejeon's apartment complexes. The results of this study can be summarized as follows: 1. Similar changes can be found throughout Daejeon's apartment complexes. As time has passed, the building-to-land ratio and the floor-to-land ratio have deceased. The high density trend of apartment complexes has continued until very recently. 2. Although residents' satisfaction with outdoor space around apartments has improved, land for athletic and commercial spaces still remains at its lowest level. Therefore, these kinds of spaces need improvement. 3. Comparing the characteristics of outdoor space in apartment complexes from the 1980s to present indicates that current apartment residents are much more satisfied with the outdoor space, but are conscious of the lack of adequate facilities for the elderly and the handicapped people, and of the hiか density of their apartment complexes. Therefore, these essential consciousness should also be further improved. 4. The residents are gradually becoming aware of changes to the outdoor space that have occurred over time in the apartment complexes, such as in the areas allowed to parking, pedestrians, and athletics. 5. These chronological changes relate to the residents' interest in the changes that have occurred to the outdoor space, especially the convenience of parking, the color of the buildings, the form of the buildings, and the shape of the roofs.
