This study was to research and study whether the types of interaction design perform the effective functions and roles as the exhibition space that audiences want centered in the digital media exhibition space. It was to suggest effective space characteristics through analyzing how the interaction design was expressed at the exhibition space and its application. For the analysis, it completes theoretical inquiry on the classification of the space characteristics according to the concept type of interaction and design characteristics. Based on it, it directly visited the exhibition space that reflected the interaction design centered in Seoul City, experienced the given experience, and designed the analyzing frame by composing a checklist after the observation research. Through the designed analysis, it performed a site questionnaire to audiences. It induced the conclusion as follows after analyzing the case space that reflected the interaction design type. First, the program analysis of the space that has the variability is necessary through a variety of digital analysis as there is a limitation that the characteristic of digital media has. Second, in the concept type of the interaction design, it needs the interaction stage among people that can communicate with audiences and stimulate their senses through vidual factors. Third, in the characteristic of the interaction design, it should try to use effective contents to get over the limitation of the space through the interaction in the designated space in case of exhibition. In the following research, it needs to study on the variety of stage plans in detail by supplying contents to audiences and grafting to the exhibition space continuously through using the interaction design that uses digital media at there.

In recent years, public complaints against railroad noise by KTX and Ordinary train have been rising. Regulation of railways noise uses same standard without distinguishing the type of railroad cars. According to the type of railroad cars, the frequency characteristics of emitting noise is different. Therefore it is requested to know how the public response vary to each types of railroad cars. The noise annoyance from three types of trains(KTX, electric train, diesel train) was analyzed by jury evaluation test for assessing the effect of frequency characteristics. The numerical results by a semantic differential method showed that annoyance response to three type of trains depended on the frequency characteristics. As a result, this study proposed that the KTX could have a bonus level of maximum 2.9 dB(A) compared to ordinary train.

On this paper, a circular unimorph-type piezoelectric transducer was proposed and studied. The transducer was fabricated by attaching a circular-shaped PZT ceramic to a circular plate of brass and output characteristics of the fabricated transducer were then analyzed and measured by changing driving points where the mechanical vibrations were applied. Two conditions depending on the location of vibration were respectively defined as a center forced model and an edge forced model. The resonance frequency and output voltage of the models were simulated by using ANSYS, a FEM(finite element method) program. Based on the results of the analyses, the vibration experiment was conducted and the output characteristics then measured through measurement equipment. As a result, the maximum output characteristics of two models were respectively generated at each resonance frequency and the resonance frequency of the center forced model was lower than the edge forced model.

The capability of pilot injection with small fuel quantity at all engine operating conditions is one of the main feature of the common rail system. The purpose of the pilot injection is to lower the engine noise and to reduce the NOx emissions. This study describes the pilot spray structure characteristics of the common-rail diesel injectors, solenoid-driven and piezo-driven type, with different electric driving characteristics So, three common-rail injectors with different electric current wave were used in this study. The pilot spray characteristics such as spray speed, spray tip penetration, and spray angle were obtained by spray images, which is measured by the back diffusion light illumination method with optical system for high-speed temporal photography. Also the CFD analysis was carried out for fuel behavior under high pressure in between needle and nozzle of solenoid-driven injector to know the condition of initial injection at experiment test. It was found that pilot injection of common-rail system was effected by rate of injection and temperature of injected fuel and electrical characteristic of the driven injector.

Helical gear excitation is transmitted to a gearbox through the shafts and bearings and the vibration of the gearbox radiates the noise in the air. Therefore gearbox modeling is essential to evaluate the gear noise. This work deals with vibration and acoustic analysis of a cylindrical shell-type gearbox with/without holes excited by helical gears and focuses on the development of the simple gearbox model. To do so, helical gears and bearing forces are calculated. Gearbox with/without holes is modeled by the aluminum end plates and PMMA cylindrical shell body. The vibration mode and the forced harmonic response were calculated by the commercial FE software and the end plate of the gearbox is more contributed to vibration than the body. Acoustic analysis was also conducted by the commercial acoustic software and a cylindrical shell type gearbox with/without holes has the similar vibro-acoustic characteristics.

Aerodynamic design of the vane type multi-function probe was tried by using CFD and wind tunnel test for the MALE UAV and small business jets. The present multi-function probe can measure total pressure, static pressure and angle of attack by using rotating vane. Therefore major performances are determined by aerodynamic characteristics of vane. In oder to design the sensor compatible to the requirement, aerodynamic characteristics of sensors was investigated by using CFD and dynamic response analysis was also performed for trasient performance. The final aerodynamic performance was measured by the wind tunnel test at Aeorsonic and the results successfully used for the design of vane type multi-function air data sensor.

Industrial agitators are used in various industrial fields where they are necessary to intimately mix two reactants in a short period of time. However, despite their widespread use, complex unsteady flow characteristics of industrial agitators are not systematically investigated. The present study alms for clarify unsteady flow characteristics induced by various impellers in a tank. Impellers are pitched blade turbine(PBT) types, Screw type and Rushton turbine type. In this study flow characteristics of the impeller using CFD. The rotating speed of impellers fixed about 100RPM. These three types of Impeller show that typical flow characteristics of axial turbine and suitable for mixing powder

The purpose of this research is to systemize the fashion digital storytelling by analyzing the communication method and its elements, and extracting the characteristics and processes of digital storytelling. Based on the previous study on the characteristics and types of storytelling the following things have been researched: 1) the process of digital storytelling in the communication process, 2) the concept and the feature of the academia of digital storytelling 3) storytelling in the document research. On the groundwork of the document research, we were able to sort out the various types, and formed a system of the features in the fashion digital storytelling cases, mainly in the four collections (Milan, Paris, London, New York) from 2000's to recent years of 2010. The types of fashion digital storytelling are episode type, narrative type, and creative type. The characteristics of each of the types are as follows. Firstly, the episode type communicates through the digital media based on the information or fact of the fashion designer brand. Secondly, narrative type communicates with the consumers using previous literature or an existing idea of the original cultural form that is rearranged in digital story expressed by the digital media. Lastly, creative type makes the designer's and consumer's susceptibility and creativity communicate through the newly made story, which expresses the unique originality of the designer. It seems that the cases and studies of using the fashion digital storytelling will increase because of its short history and lack of the case study. Fashion designer brands will show their brand image using the digital storytelling because they are able to better express originality, creativity and imagination of the fashion designer, which were factors that could not be conveyed through fashion alone.
