This study is intended to propose a plan index that can be used in the early stage of a museum design based on theoretical review of a major space of a museum including its spatial division, functions and roles. The scope of the study includes functions and roles of circulation in a major space based on precedent studies. The spatial range is limited to a major space among exhibition spaces in a museum. This study analyzes overseas 14 museums. In terms of methodology, the study analyzes circulation in a descriptive way only In the focusing on floor plan and section composition. The results of this study are as follows. First, vertical elements should be critically considered in a circulation plan for functional performance of dimensional circulation distribution in a major space. Second, a plan by location of vertical and horizontal moving elements related to a major space affects a circulation relation more than a connection type between a major space and an exhibition area.

This study aims to analyze general features and forms of spatial structure of major space in museums and for the scope of this study, set up major space and the surrounding areas structured around major space and for the target of analysis, selected 10 museums of overseas examples from 19th century to 2006. And this study on focus, on the circulation structure and visual structure will be analyzed in qualitative method by focusing on the floor plan and section structures; deepening process of analysis, visual structure will turn into numerical value to analyze the spatial structure of the major space. The results of this study are as follow. First, vertical elements should be critically considered in a circulation plan for functional performance of dimensional circulation distribution in a major space. Second, a plan by location of vertical and horizontal moving elements related to a major space affects a circulation relation more than a connection type between a major space and an exhibition area. Third, it could be categorized into 4 types by considering the features of spatial structure followed by connecting relationship between areas. Fourth, comparable figures were drawn out among large space and surrounding areas but it couldn't draw out types.

We present galaxy luminosity functions (LFs) of subgroups in the Ursa Major cluster. The membership of galaxies is determined by radial velocities which are compiled from the SDSS and NED. We found that the faint end slope (${\alpha}$) of the LF of all sample galaxies in Ursa Major is ${\alpha}=-1.13$. This is consistent with previous result, but shallower than that of the Virgo cluster. Interestingly, the subgroups in Ursa Major show different slopes in their LFs. The NGC 3992 and NGC 4111, the massive subgroups in the Ursa Major cluster, exhibit steep slopes of their LFs comparable to that of the Virgo cluster. On the other hand, less massive group (NGC 3877) shows a very shallow slope of -0.84. Based on the results, we discuss the evolution of galaxies and the assembly history of the Ursa Major cluster.

미국, 중국, 러시아 등 우주 선진국들은 일반적인 지상기반의 우주능력뿐만 아니라 해상기반의 우주능력도 보유하고 있다. 해상기반 우주시스템에는 해상기반 우주감시시스템, 해상기반 우주발사체, 해상기반 우주정보 송·수신 시스템 등이 있으며, 이러한 해상기반의 시스템들은 지상기반의 우주시스템들을 보완해주는 역할을 한다. 따라서 본 논문에서는 주요국가의 해상기반 우주능력을 분석하고, 이를 토대로 우리나라의 해상기반 우주능력의 발전방향을 제안한다. 삼면이 바다인 우리나라의 지리적 특성상 해상기반의 우주시스템은 필수적이며, 우주분야 7대강국으로 발돋움하기 위한 중요한 전략적 요소라고 판단된다.

According to the change in diverse tendency of residents, construction companies has developed the brands of apartments with the concepts of LOHAS, well-being, ubiquitous, etc. The purpose of this study was to suggest space requirement and planning for residents characteristics. The questionnaire survey was adopted in this study and 252 cases were used for data analysis. The survey analysis has been made by using of SPSS WIN 12.0. The major findings were as follows; (1) Resident opinion about the direction of each space was investigated into the need of South-facing in master bedroom highly. (2) The residents didn't want to decrease the current size of each space, the space which wanted to increase was livingroom. (3) The significant variables of space requirement and planning for residents characteristics were family life cycle, the age of householder, the occupation of householder, the size of apartment.

We present ultraviolet (UV) properties of dwarf galaxies in the Ursa Major cluster comparing with those in the Virgo cluster. We have constructed SDSS DR7/GALEX GR5 matched optical/UV catalog for dwarf galaxies with various morphologies in these two clusters. Membership of galaxies belonging to the Ursa Major cluster was made by hierarchical grouping method using SDSS spectroscopic data. We classified morphologies of dwarf galaxies using the combination of visual inspection of the images and spectral features returned from SDSS data. In contrast to the case of the Virgo cluster, majority of dwarf galaxies in the Ursa Major cluster lies in the blue cloud of the UV color-magnitude relations (CMRs) implying strong recent or on-going star formation. We discuss the cluster environment on the star formation history and evolution of dwarf galaxies.

Archival long-slit spectra, covering the wavelength range 4050~5150$\AA$, have been used to investigate the radial behavior of absorption line features (G4300, Fe4383, Ca4455, Fe44531, Fe4668, and H$\beta$) of an eliptical galaxy NGC 5322. The heliocentric recession velocity of NGC 5322 has been derived as 1888$\pm$51kms-1. Metallic absorption lines of NGC 5322 show significant radial gradients through the major axis. The minor axis shows much smaller radial metal line gradients than the major axis. The minor axis shows much smaller radial metal line gradients than the major axis. The mean slopes of Fe line gradients to the major and minor axes of NGC 5322 were estimated as -0.433$\pm$0.064 and -0.242$\pm$0.096, respectively. Significant radial gradients of H$\beta$ absorption of NGC 5322 are also detected both on the major and minor axes. It is shown that the radial metallicity gradients in NGC 5322 are smaller than expected in a simple dissipative collapse model. Rather, dissipationless collapse, such as hierarchical merhing, could have contributed during the initial stage of the galaxy formation.
