An irregular cell-based numerical model was developed to analyze underground space flooding. In this model, the flow characteristics in underground space were computed by link-node system. Also, the model can simulate the underground flood flow related to the influence of stairs and wall-structures. Empirical discharge formula were introduced to analyze weir-type flow for shopping mall, and channel-type flow for subway railroad respectively. The simulated results matched in reasonable range compared with the observed depth. The dual-drainage inundation analysis model and the underground space flood analysis model were integrated using visual basic application of ArcGIS system. The developed model can help the decision support system of flood control authority for redesigning and constructing flood prevention structures and making the potential inundation zone, and establishing flood-mitigation measures.

In order to increase the utilization of limited space in urban area, it can be a good solution to make use of underground space. For the last few decades, underground space systems, such as underground passages, subway stations, and underground shopping arcades, have been constructed in many cities all over the country. Despite of the advantages on the utilization of space in urban area, underground space systems have always been exposed to the risk of inundations resulted from severe rain storms. In this study, it has been examined to apply 2-D flow models (TUFLOW and FLUMEN) to establishing the preventive measures to the risk of flood. For the part with relatively complex configuration, such as a corridor junction, 2-D flow models present the detailed information about the effect of geometry on the inundation events and the temporal and spatial distribution of inundation over the space. From the result, it can be concluded that the 2-D flow model can be the effective implement for establishing the proper measure to the inundation on underground space systems, which generally have relatively long and narrow geometry with complex inner configuration.

The topic on Flow is generating increased interests in e-commerce studies. Flow has been identified as a key component in e-commerce. Studies on Flow have so far focused on internet shopping mall, but scarcely looked at the Flow of Internet auction. The purpose of study is to find out which factors play a major role in building Flow on internet auction and how the built-up Flow affect Brand Equity. Therefore, the research model investigates what factors influence Flow. Furthermore, the research is designed to understand how the Flow influences Brand Equity. The antecedents of Flow classifies into three types such as personal (Challenge, Skill), IT characteristic, Internet Auction characteristic. The results of this empirical study shows that three characteristics significantly affected the flow：personal (Challenge), IT (information quality, system quality), and Internet Auction (interactivity). And also Flow has significant effect on the brand equity. This result indicates that customer's optimal experience is important to increase brand equity. That is, the flow is influenced by multi-dimensional factors and plays an important role in increasing brand equity. Finally, the finding of this study suggests that personal challenge, information quality, system quality, and interactivity should be enhanced preferentially.

Braced excavation systems are commonly required to ensure stability in construction of basements for shopping malls, underground transportation and other habitation facilities. For excavations in deposits of soft clays or residual soils, stiff retaining wall systems such as diaphragm walls are commonly adopted to restrain the ground movements and wall deflections in order to prevent damage to surrounding buildings and utilities. The ground surface settlement behind the excavation is closely associated with the magnitude of basal heave and the wall deflections and is also greatly influenced by the possible groundwater drawdown caused by potential wall leakage, flow from beneath the wall, flow from perched water and along the wall interface or poor panel connections due to the less satisfactory quality. This paper numerically investigates the influences of excavation geometries, the system stiffness, the soil properties and the groundwater drawdown on ground surface settlement and develops a simplified maximum surface settlement Logarithm Regression model for the maximum ground surface settlement estimation. The settlements estimated by this model compare favorably with a number of published and instrumented records.

This study has examined the shift in fashion styles in Korea by analyzing trends in fashion environment and fashion image by seasons in Korea to understand the domestic fashion flow from 2000 to 2006. Since 2000, with the well-being trend, polarization of consumption, preference in luxury orientation, and digital revolution, consumers became individualized and detail oriented. They also became smart consumers equipped with information and knowledge in making choice and purchasing products suiting their taste. To satisfy the consumer trend, fashion market also saw changes such as expansion of advanced distribution, totalization of brands, growing of on-line shopping mall, expansion of outdoor-wear market, and formation of masstage(mass+prestage) market. Fashion images in domestic women's wear since 2000 are analyzed as classic, elegant, minimalism, romantic, bohemian & vintage, ethnic, glam, girlish, kidult, sportive, femiculine, military, and lingerie image. Classic, romantic, and bohemian & vintage are the images that were popular throughout 2000 to 2006. Fashion images of domestic women's wear showed changes in three periods: Sportive image was popular in FW 2002; military image in SS 2003 to SS 2005; and femiculine, glam, and minimalism images in FW 2005 to FW 2006. Through information and detail-oriented emotion, the wide-ranging acceptance of global trends, the consumer tendency towards purchasing products quickly and conveniently, the speedy supply of trendy products both on-line and in-store, and the evolution of the fashion market towards providing one-stop shopping and a cultural space, different fashion images have all emerged at the same time in Korea. It looks like this phenomenon is set to continue for a while.

Omni-channel strategy is an innovative paradigm for integrated information distribution of inventory, sales, operations, marketing, delivery, pickups and returns in supply chain management. Recently the distribution strategy faces new challenges with the advent of mobile distribution channels. Social media with countless apps imposes additional stress on supply chain operations. Due to these changes, distribution network in supply chain is changing naturally and rapidly from multi-channel to omnni-channel platform. Recently numerous domestic distributors establish and adapt this new supply chain optimization tool as a part of seamless flow of movements of goods from one channel to other channels. The objective of this paper is to present a preliminary findings on how omnni-channel affects the supply chain management. A survey is used to ascertain in the degree of omnni-channel implementation and statistical evidence is provided to test sets of hypothesis. The results of the questionnaire showed that consumers' purchasing styles differed by gender, age, purchase purpose, and product type. In particular, women consider purchasing experience in omni-channel to be important. As food and household goods can be conveniently shipped, consumers prefer online purchasing it. Conversely, consumers tend to favor omni-channel strategy in connection with offline experience in IT products.
