  • The prediction of the separation trajectories of external stores released from a military aircraft is an important task in the aircraft design area having the objective to define the operational and release envelopes. This paper presents the results obtained for store separation by employing commercial softwares, FLUENT and CFD-FASTRAN. FLUENT treats the rigid body motion by employing a remeshing scheme. CFD-FASTRAN uses Chimera(overset) grid and interpolations. It was found that, for the prediction of the trajectories and behavior of the stores separated from the wing, both codes show the good agreement with the experimental results.

  • The purpose of this study was to investigate the causes of bankruptcy in small apparel stores. Data were collected from 153 apparel retail store owners who experienced failure in small apparel stores in Busan. The results showed as follows; The internal factors that caused bankruptcy in small apparel stores were the problems related with employees, capital, investment, weak marketing strategies, inadequate management, and characteristics of store owners. The external factors were economic condition, unexpected incidents, and the condition of market. There were significant differences in the perception of factors which caused the store bankruptcy according to prior business experience before opening apparel stores, the level of education, and the period between store opening and closing.

  • Granular Activated Carbon (GAC) has been proven to be an excellent material for many industrial applications. A systematic study has been carried out of the kinetics of physical as well as chemical activation of phenolic resin chars. Physical activation was carried out using $CO_2$ and chemical activation using KOH as activating agent. There are number of factors which influence the rate of activation. The activation temperature and residence time at HTT varied in the range $550{\sim}1000^{\circ}C$ and $\frac{1}{2}{\sim}8$ hrs respectively. Kinetic studies show that the rate of chemical activation is 10 times faster than physical activation even at much lower temperature. Above study show that the chemical activation process is suitable to prepare granular activated carbon with very high surface area i.e.$ 2895\;m^2/g$ in short duration of time i.e. 1 to 2 hrs at lower temperature i.e. $750^{\circ}C$ from phenolic resins.

  • Aircraft should be equipped with various external stores for mission performance. Since these external stores may cause structural instability of aircraft, an evaluation of the effects between the aircraft and the external stores is required. For this purpose, an aircraft dynamic characteristics analysis reflecting an external store was performed, and the finite element model for the analysis of aircraft dynamic characteristics should simulate the dynamic characteristics of the component as accurately as possible while using a minimum of the nodes and elements. In this study, a stick model was constructed for dynamic characteristics analysis of the external fuel tank and installation pylon using MSC Patran/Nastran. For the calculation of the equivalent stiffness of the stick model, a simple beam theory was applied to construct the stick model of each part, and the validity of each stick models was confirmed by mode comparison with the fine model. Additionally, the model analysis of the stick model assembly, simulating a pylon equipped with an external fuel tank was performed to confirm that the basic modes required for the analysis of aircraft dynamic characteristics are well extracted. Finally, it was confirmed that the developed stick model assembly could be used for analysis of aircraft dynamic characteristics by comparing the errors in modes between the fine model assembly and the stick model assembly.

  • Recently, it is considered that the fashion flagship stores are being standardized as they are focusing only on external decorations and that they are hardly expressing their own intrinsic identities. That being the case, the fashion flagship stores are, now, pursuing diversity and are trying for any experimental designs in order to make their spaces more unique than those of other fashion flagship stores are, and regarding customers who would visit the stores, they have this desire to experience spaces, which are all unusual and different, just quickly while they shop. The topic of this study, depaysement which is making it unfamiliar, applies some unfamiliar a stimulus to people, and that makes the users remember this realization of original images and psychological stimuli as long as possible as leading the users to experience those spaces of special values. In the light of that, this study categorizes the features of depaysement into those groups, such as distortion of scales, juxtaposition of foreign materials, fantasy and ambiguity of a boundary, and analyzes the interior spaces of the fashion flagship stores. After all, this study applies depaysement to the fashion flagship stores' interior spaces, which have been all familiarized and standardized through some habitual relations, and works on different stimuli in order to invite the users to experiences of those totally new senses which are different from what the users have been felt in their daily lives. In the end, the study aims to propose ideas for how to design a place attractive enough to make the users revisit the place as after going through such memory process mentioned on the above.

  • Successful use of displays in stores arouses consumers' curiosity, and induces them to purchase a product after a visit. Facade is a word meaning an external front wall of a building, and is usually the first point of visual contact for the consumers. The present study is an empirical investigation of external appearance of a clothing store, with a $2{\times}2{\times}2$ factorial design of facade, show window, and wall surface material designed for the purpose of the study. Dependent variables were store image variables and attitude toward store. A total of 320 questionnaires from male and female consumers were used for the analysis. Facade type and material had significant main and interaction effects, while show window type had no meaningful effects overall. A facade of irregular design prompted significantly higher levels of perceived 'elegance', 'uniqueness', and 'attractiveness' of the store. Material itself did not have significant influence but did have significant interaction effect with facade design. The interaction effect was found in store attitude as well. In order to create a positive store attitude, a concrete material facade should have an irregular design. Companies owning fashion brands should carefully select facade type and wall surface material in the visual merchandising strategies of a store.

  • As the role of retail stores in distribution channels becomes more significant and competition among them becomes more fierce, retail stores are making efforts to gain a dominant position in market share. And as such, consumer store choice behaviour is becoming more diverse and complex. The purpose of this study was to analysis the store choice process and to aid in understanding the types of store choice behaviors. 30 subjects were sampled by focus sampling and investigated by in-depth interview. Some consumers went through all stages of store choice process and others skipped some. The consumers who usually had no plan to visit stores and who purchase without problem recognition process were categorized as opportunity-taking type, and the consumers who visited just one store without external search of other store information were categorized as store-loyal type. Finally, the consumers who searched store information externally were divided into brand-oriented type and value-seeking type. The brand-oriented type represented the consumers who did not evaluate stores in detail because which store to visit was decided on brand; and the value-seeking type represented the consumers who did in fact evaluate stores in more detail according to the items and trends in fashion. This study is meaningful in that it provides a dynamic store choice process and examines related variables thereto.
