Shopping malls in Seoul become important urban public space where teens and youths as well as the elderly come easily and enjoy thorned environment. This study examines design motifs, structures and effects of theme design of three shopping malls-Lotte World, Coex Mall, and Central City-in Seoul, Korea. The study quotes Lynch`s five image elements-paths, nodes, landmarks, districts, and edges in the shopping malls in order to analyze internal structure of the shopping malls and theme design elements. The theme design of the shopping malls was often used the images of "city parks", "future city", "foreign tourist places", "carnival and festival", and "old towns" to evoke nostalgia of the past and fantasy of the future. The study finds that theme design was emphasized at the area of corridors-path, plazas-nodes and special districts such as movie theater and food courts. The study concludes that theme design in the three shopping malls should consider local(Korean) motifs in design properly and consider educative effects of the design on teens and youths. Thus, theme design of the shopping malls should meet multi-functional roles of the spaces aesthetically and socially, The data and analysis of this study can contribute to improve theme design of shopping malls in Seoul, Korea.ve theme design of shopping malls in Seoul, Korea.

The purpose of this study is to propose a planning method for increasing visitors' usage attraction by understanding user circulation in the large scale commercial complex. Focusing on the impact of anchor tenant on the pedestrian traffic arousing visitors' usage attraction flow, this study analyzed pedestrian circulation and traffic volume of Lotte World Mall, a large scale commercial complex. In this study, the change of pedestrian traffic in the commercial complex was investigated and the circulation flow of anchor tenant visitors such as movie theater in the commercial complex was simulated by computer. By analyzing both characteristics of pedestrian circulation and traffic volume in large scale commercial complex and movie theater users' pedestrian traffic with network-based computer simulation, positive relationship between pedestrian traffic to movie theater and pedestrian traffic dispersion of the whole commercial complex users was emerged. In addition, It is necessary to plan of distributing pedestrian traffic of vertical moving line in central space appropriately for using attraction function of anchor tenant.

This paper numerically and experimentally investigates the control performance of the active mass damper (AMD) systems in a 26-story high-rise building in use. This is the first full-scale application of the AMD system for suppressing the wind-induced vibration of a building structure in Korea. In addition, the AMD system was installed on top of the building already in use, which may be the world's first implementation case. In order to simultaneously mitigate the transverse-torsional coupled vibration of the building, two AMD systems were applied. Moreover, the H-infinity control algorithm has been developed to utilize the maximum capacity of the AMD system. From the results of numerical simulation using the wind load obtained from the wind tunnel tests, it was found that the maximum acceleration responses of the building were reduced significantly. Moreover, the control performance of the installed AMD system was examined by carrying out the free and forced vibration tests. The acceleration responses on top of the building in the controlled case measured under strong wind loads were compared with those in the uncontrolled case numerically simulated by using the wind load deduced from the measured data and a structural model of the building. It is demonstrated that the AMD system shows good control performance in reducing the building accelerations.

The objective of this study is to investigate the influence that how does contact surface between concrete and steel influence the steel encased composite column by push-out test. Also nominal bond stress indicated by design standard such as Eurocode 4 is underestimated in small scale steel encased composite column. The other objective of this study is to investigate how does the number and space of shear connector influence the H-shaped steel encased composite column. The shear behavior of shear connectors is investigated by push-out test.

This study intends to analyze the structural relationships among the servicescape of theme park, the affective image and the place dependence of visitors, one of the most important factors of place attachment. For this purpose, this study selects Lotte World in Seoul as a study site and conducts a questionnaire survey focused on visitors who visited the site previously. The results of an exploratory factor analysis, confirmatory factor analysis and structural equation method show that esthetics and amenity factors among servicescape of theme park affect the attractiveness and comfortableness of the affective image of visitors positively, and two factors of visitors' affective image also affect the their place dependence positively. Tourism planners or landscape designers can consider these useful servicescape elements of theme park as important planning and managing factors in order to improve the images of theme parks and the level of place attachment.

Gradual mortality of look down fish (Selene vomer) was observed in a private aquarium in Seoul, showing abnormal swimming behavior and lethargy. A bacterial pathogen from kidney was cultured, identified, and confirmed as Vibrio harveyi using Vitek System 2 and 16S rRNA gene sequencing. A predominant bacterial strain, SNUVh-LW2 was proved to be most closely related to isolates from China by phylogenetic analysis with minimum evolution method. Also, tetracycline was considered as the most sensitive antibiotic agent via antibiotic susceptibility test. The group of fish was treated according to the diagnostic result and no more mortality was observed.
