The purpose of this paper is to reconstruct the original floor plan and wall design of Seokbulsa Grotto in Kyungju; commonly known as 'Seokguram'. The paper presents an array of dimensional studies of the existing Seokguram to examine its architectural form, and infers the original floor plan and wall design of Seokbulsa Grotto. Seokbulsa Grotto is designed as a system of 'coherent modules' and was constructed using the dry stone method, which interlocks large stone modules into a whole that becomes the load-bearing structure itself. The design principles governing Seokbulsa Grotto are the spatial axis of symmetry, modular coordination, and the layout grid of a quarter Tang-Ruler(TR: 唐尺). Dimensional studies were conducted with these governing principles in mind and concludes the following about the original floor plan design. In the main chamber, Ansang-stone's radius is 12 TR, and Flagstone's radius is 12¼ TR. In the front chamber, the width between the two Ansang-stones facing each other is 22 TR and the longitudinal space depth is 12 TR, while the width between the two Flagstones facing each other is 22½ TR and Flagstone's depth is 12 TR. In the passageway, the width between the two Ansang-stones facing each other is 11½ TR and longitudinal space depth is 9 TR, while the width between the two Flagstones facing each other is 12 TR and Flagstone's depth is 7¾ TR. The distance from the center to the entrance line of the main chamber is 10½ TR. Therefore, the total longitudinal length of the Grotto is 43½ TR at the level of the Ansang-stones, and 44 TR at the level of the Flagstones.

도심지 터널공사에서는 주변 건물의 안전성을 확보하고, 민원을 최소화할 수 있는 쉴드TBM 공법이 대부분 적용되고 있다. 도심지에는 기존의 택지를 매립조성하거나 개량하는 경우가 많기 때문에 지표에서부터 암반 경계부까지는 불균질한 상태로 이루어지는 경우가 많다. 이와 같이 토사지반, 파쇄정도가 다양한 화강암지반, 핵석층, 암층과 같이 복잡한 지반 조건에서 쉴드TBM으로 터널구조물을 구축하는 경우, 각 지반조건에 따른 쉴드TBM에 나타나는 기계데이터를 분석하여 지반조건에 따른 장비부하의 특징을 비교분석하였다. 그 결과, 설계막장압을 유지하면서 굴진하고, 주기적으로 커터를 점검하여 교체하는 경우, 배토량, 추력, 커터토오크의 경향으로 지반조건의 변화를 예측할 수 있을 것으로 판단된다.

Busanjin Fortress was originally made of stone fortress for the Joseon Navy, which was located in Dongnae area in the late Joseon Dynasty. However, the Japanesque Castle of Busanjin in 1592 was built by the Japanese military during the Japanese Invasion of Korea. Since the Japanese military retreated, the Joseon Navy had renovated the fortress and had used it as a base for stationing, and it had been maintained in Busanjin Fortress until the Joseon Navy was disbanded in 1895. After the abolition of the Naval Force System, the space in Busanjin Fortress was dismantled, and the government facilities and their sites were not properly managed and repaired, eventually was sold to Japanese. As Busanjin Fortress failed to function properly, the coastal space in Busanjin became a burial ground after being reclaimed by Japanese with real estate investment in mind. Today, the traces of Busanjin Fortress have been removed by the reclamation work, and only the remains of some stone pillars remain under the name of Jaseongdae(子城臺). Thus, the old custom as the Naval base disappeared, leaving only the image of Japanesque Castle.

This study aimed to elucidate the architectural characteristics of the cathedral architecture of the Archdiocese of Gwangju, which was completed in the period of liberation and turbulence, and the conclusions are as follows. Gwangju Archdiocese Cathedral, completed during the period of liberation and turbulence, was built with some assistance from the U.S. military or with the efforts of the faithful, and there are a number of factors such as space directing by Aps, the development of a simplified bell tower, the appearance of a stone cathedral, the application of a quenset structure, and an increase in size. show special features The indented apse appears only after liberation, and is a characteristic that appears prominently in stone churches. The simplified form in which the bell was hung by raising the outer wall appeared in the early church shows a change in the composition with a porch in front. The stone church and the quanset-structured church only appeared after liberation and were built only in the 1950s. The size of the cathedral reflects the increase in the number of believers after the Korean War, and the average area is about 1.5 times higher than before liberation. When considering the spacing of the bays as a module, the size plan followed the implicit norm of early cathedral architecture of 36.5m, but gradually decreased to 2.7m and 2.4m.

In this paper, we construct a cover ($\mathcal{L}(X)$, $c_X$) of a space X such that for any cloz-cover (Y, f) of X, there is a covering map g : $Y{\longrightarrow}\mathcal{L}(X)$ with $c_X{\circ}g=f$. Using this, we show that every Tychonoff space X has a minimal cloz-cover ($E_{cc}(X)$, $z_X$) and that for a strongly zero-dimensional space X, ${\beta}E_{cc}(X)=E_{cc}({\beta}X)$ if and only if $E_{cc}(X)$ is $z^{\sharp}$-embedded in $E_{cc}({\beta}X)$.

In the early of Joseon Dynasty, Royal Tomb developed from stone chamber tomb to lime chamber tomb through precedents. The lime chamber tomb consists of main-chamber(JeongGwang) and sub-chamber(ToeGwang). This separation makes character to construct tumulus of the Royal Tomb half and half. By this character, the Royal Tomb are not constructed by separate structure but constructed by coadjustment. The underground structure and tumulus of the Royal Tomb affect each other in the size and method of construction. The selecting type of Royal Tomb is generally made decision through terrain and politics. This study prove the architectural structure is also one of the major cause the that select type of Royal Tomb.

This paper presents the nearfield acoustic holography (NAH) imaging system for airborne sound constructed in our own laboratory. The effects of different kinds of noise and the filter function's form in wave number space for reconstructions are analysed emphatically. Using the system we have measured the vibrating mode and the radiated field of a simulative "Chime Stone" made by metal, and gotten interesting results. These results indicate that NAH can be used to research the mechanism of sound production and evalution of musical quality for Chime Stone as an effective means.

In this paper, we first show that $z_{{\kappa}X}:E_{cc}({\kappa}X){\rightarrow}{\kappa}X$ is $z^{\sharp}$-irreducible and that if $\mathcal{G}(E_{cc}({\beta}X))$ is a base for closed sets in ${\beta}X$, then $E_{cc}({\kappa}X)$ is $C^*$-embedded in $E_{cc}({\beta}X)$, where ${\kappa}X$ is the extension of X such that $vX{\subseteq}{\kappa}X{\subseteq}{\beta}X$ and ${\kappa}X$ is weakly Lindel$\ddot{o}$f. Using these, we will show that if $\mathcal{G}({\beta}X)$ is a base for closed sets in ${\beta}X$ and for any weakly Lindel$\ddot{o}$f space Y with $X{\subseteq}Y{\subseteq}{\kappa}X$, ${\kappa}X=Y$, then $kE_{cc}(X)=E_{cc}({\kappa}X)$ if and only if ${\beta}E_{cc}(X)=E_{cc}({\beta}X)$.

As environmentally friendly life styles become more popular these days, the landscape elements like plants, water, stone etc. which used be considered as just simple interior props, now become the main design concept that decides the whole image of space. The purpose of this thesis is to study the various understandings and approaches on the applications of the landscape elements which are known as the most friendly and positive ways to approach the senses of users, among any other methods and techniques for environmentally friendly elements. The application types of landscape elements in interior space design are as follows; (1) incorporate the surrounding landscape elements. Keeping existing landscape elements, incorporate them into interior elements of beauty; (2) install a transition space with landscape elements; (3) green interior planes ;(4) use landscape as the main design concept; (5) use landscape as decoration elements. Many of landscape spaces incorporated into the interior are often built in a hurry and in low qualities without much consideration of the users and the space. This study intends to set a standard for the application of landscape elements in space design, after collecting various cases that applied the landscape elements in interior space, by categorizing the successful and effective applications into applicable patterns.
