It is widely accepted that the evolution of galaxies is accelerated in dense environments. According to recent studies, however, the evolution by direct interactions between galaxies is known to be most active in a galaxy group rather than in a galaxy cluster. In particular, the central galaxy in a group is closely related to its satellites in the properties such as morphology, color and star formation rate, because those galaxies evolve together in a small-scale environment. Currently, however, it is not yet studied well whether such conformity between bright galaxies and their faint companions remains after a galaxy group falls into a galaxy cluster. Recently, Lee et al. (2014) have found that the colors of bright galaxies show a measurable correlation with the mean colors of faint companions around them in WHL J085910.0+294957, a galaxy cluster at z = 0.3, which may be the vestige of infallen groups in the cluster. As a follow-up study, we study Abell 2744, an ongoing cluster-cluster merger at z = 0.308, using the HST Frontier Fields Survey data. The cluster members are selected based on the distributions of color, size and concentration along magnitude. The correlation in color between bright galaxies and their companions is not found in the full area of Abell 2744. However, when the area is limited to the southeastern part of the Abell 2744 image, the mean color of faint companions shows marginal dependence (> $2{\sigma}$ to Bootstrap uncertainties) on the color of their adjacent bright galaxy. We discuss the implication of these results, focusing on their dependence on local environments.

The rising urban space in the United States at the turn of the twentieth century was an exemplary site of struggles between the dominant white population and those who migrated from the imperial peripheries. By setting up the space of Chinatown as a segregated sphere within the urban space, the dominant white American society attempted to recreate the sense of distance between themselves and the racial "others." Accordingly, the dominant narrative representations of San Francisco Chinatown at the turn of the century endeavored to produce and maintain the spatial dichotomies between the orderly spaces of natives and the disruptive immigrant communities within the larger boundary of modern American city space. As a Eurasian woman writer, Sui Sin Far attempted to provide distinctive portrayals of the space of Chinatown and its inhabitants that were far different from those of her contemporaries. Through her portrayals of San Francisco Chinatown in her collection of short-stories, Mrs. Spring Fragrance and Other Writings (1912), Far challenges against the false stereotypes and misreading of this unique immigrant space within and efforts to present the Chinatown as a heterotopic diaspora space where the "insiders" and the "outsiders" of the American urban space intermingle and influence each other.

Turbulence produces the density and velocity fluctuations in molecular clouds, and dense regions within the density fluctuation are the birthplace of stars. Also, turbulence can produce non-thermal pressure against gravity. Thus, turbulence plays a crucial roles in controlling star formation. However, despite many years of study, the detailed relation between turbulence and star formation remain poorly understood. As part of the Taeduk Radio Astronomy Observatory (TRAO) Key Science Program (KSP), "mapping Turbulent properties In star-forming MolEcular clouds down to the Sonic scale (TIMES; PI: Jeong-Eun Lee)", we mapped two star-forming molecular clouds, the Orion A and the ρ Ophiuchus molecular clouds, in six molecular lines (¹³CO 1-0/C¹⁸O 1-0, HCN 1-0/HCO⁺ 1-0, and CS 2-1/N₂H⁺ 1-0) using the TRAO 14-m telescope. We applied the Principal Component Analysis (PCA) to the observed data in two different ways. The first method is analyzing the variation of line intensities in velocity space to evaluate the velocity power spectrum of underlying turbulence. We investigated the relation between the star formation activities and properties of turbulence. The other method is analyzing the variation of the integrated intensities between the molecular lines to find the characteristic correlation between them. We found that the HCN, HCO⁺, and CS lines well correlate with each other in the integral shaped filament in the Orion A cloud, while the HCO⁺ line is anti-correlate with the HCN and CS lines in L1688 of the Ophiuchus cloud.

The progress made by scientific development achieved the goal for making human environment convenient and functional. However, it also caused excessive expanse of artificial environment, which in turn produced undesirable segregation between human and nature. Recently we frequently see ecological space designs which try to be synchronized with nature not only in technological terms, but also in psychological terms. This paper examines various viewpoints for ecological space design. First, it studies philosophical backgrounds of ecological space design through comparative analysis between eastern and western ideas of nature. Then it classifies the types of viewpoints for ecological space design with supporting explanations from scientific proofs. Finally, it provides case analyses for each of these views. This research aims at proving the value of ecological space design so that it can guide future direction of space design toward reestablishing the organic relationship between human and nature.

In the relationship between exhibition space and art work in art museum, the Pluralism on the late of the 20th century made the new form of exhibition space to be appeared on the stage. Even if formal exhibition space that emphasized itself as a non-spatial background is currently being continued, the informal form of exhibition space is coming to the new art museums, especially after 1990's. This study is to understand how the advent of new designed the informal form of exhibition space in the Glytothek museum(the formal form of exhibition space) design a new paradigm In the relation between the exhibition space and art work in conjunction with public's perception. To do this, it is made clear that the Glytothek museum(the formal form of exhibition space) simply has played a role of non-spatial background. In other hands, the new designed informal form of exhibition space that is mainly presented after 1990's begins to Interrupt the public's perception of art work, changing it's meaning through a spatiality.

The purpose of the study is to present the social welfare center planning factors of space for promoting intergenerational exchanges between the elderly and children. To achieve the purpose, the study conducted a survey of professionals on the importance of planning factors. The results are as follows. First, it is surveyed that less high are Korean social welfare center planning and availability extents of space for intergenerational exchanges, while less no profound are the necessity and concern of such spaces. The result suggests that social welfare centers need a concrete planning of space for intergenerational exchanges. Second, it is identified that in order to promote intergenerational exchanges, there need to plan planning factors of each space, especially with focus on 'outdoor space' and 'specific space.' Third, it is revealed that regarding the importance of factors of 'specific space,' physical supports account for the high rates; architectural factors providing free space contribute to the supports of physical development; and decorative factors giving visual effects could be helpful for behaviors. Fourth, it is unveiled that the supports of physical behaviors are of the most importance in 'connecting space'. This would be planned as a path that gives a free access in spaces, with attention being paid to safety. Lastly, it is shown that in the case of 'outdoor space,' the supports of physical development are of the most importance. Given the fact that 'outdoor space' offers a wider scope of activities, and accommodates various available elements in connection with surrounding environments, it is considered that the space would be of help for intergenerational interactions. The study is expected to be utilized as the preliminary data which proposes the social welfare center planning factors of space for promoting intergenerational exchanges between the elderly and children.

In order to make an effective use of spatial resources in the city, detailed environmental plan strategies based on 'culture' are needed. An integral part of city spaces-'underground space' serves as one of the spatial resources with much effective usage potentials. Hence, 'underground space' needs cultural vitality. The purpose of this study is to propose an thorough indoor environmental plan guideline for the cultural vitality of 'underground space'. The methods used to conduct research include precedent study reviews and survey. Through this research, following conclusions are drawn. First, to promote cultural vitality at the 'underground space', it must be transformed into the cultural public place to be utilized for cultural activities by residents. Second, the 'underground space' requires 'concept of eco-friendly space for clean environment'. Third, 'safe environment' concept must be installed in the 'underground space' to promote the cultural vitality. Fourth, the 'underground space' requires 'complex/block level network plans between cultural spaces in addition to horizontal/vertical walking network between cultural environments in ground level and underground spaces. Fifth, the 'underground space' requires underground public cultural space plan through 'reasonable underground development with considerations of the facilities related to education, culture and history'. Sixth, 'public cultural space plan for various cultural spaces' and 'supply of space for cultural activities for residents and design plan for mutual culture exchange' are necessary.

This paper was conducted to compare the methods of women's basic pattern and the problems by analyzing the space between skin and clothing using 3D scanner and thereupon, proposed the solutions. The Bunka pattern of Japan Bunka Women's University(Bunka) and the Secoli pattern of Italy istituto carlo secoli(Secoli) were used. The subject who has nearly the same body size with N type of National anthropometric survey of Korea in 1997 was picked out. In the result of analyzing the space between skin and clothing of each pattern by 3D Scanner, there exist significant differences in the chest and bust parts. The Bunka has more space than the Secoli at bust part, especially between bust points. Because the Bunka has the bust dart which was made from only the bust girth, it couldn't reflect the difference of each human body. Whereas the Secoli has the bust dart which gave a consideration the difference between the bust girth and the chest girth, it has more even space between skin and clothing.

Digital technology in modern society is entering the era of digital convergence and ubiquitous computing, and is playing an important role to overcome the limitation of time and space. Based on new media method's rapid application development, a wide range of forms as digital design is made possible. A large part of our living such as information sharing, collaboration, production, recreation, working and various social activities has been realized from the space that digital media offer. As we see a much broader range, the digital media's diverse expressions affect, in interactive ways, not only the relationship between humans and things, between each individual human, and between humans and the environment, but also even emotional purification and realm of educational, cultural, and social aspect. In this study, the aim is to discuss the user-centered design considered for integration into the interaction space design method and is to concentrate on research on. Focusing on digital media, user-friendly interface features of the space environment, construction and utilization of digital media have been applied to try to analyze the interaction effect of space that is created for the design and application of various applications and will seek ways. Thus, various case-studies have been explored where interface space is developed, creating virtual reality through cognitive basis and 3-D interface space. For example, emotional expressions are embedded for the space of commerce, education and exhibition, enabling intercommunication through haptic interface, with changing sound and visual effects which are caused by the movement of people in a certain space. With consideration of the relationship between physical environment and objects, interactive design should be achieved by providing a human oriented interface based on social, cultural and environmental aspects.
