  • The purpose of this study is to suggest unit design considerations for college student's rental houses. To achieve this purpose, life pattern, residential space usage and housing needs were investigated. Data were collected by in-person interviews. Interview participants were 37 single undergraduate students living near the Shinchon station subway line 2. Subjects were selected by housing types-a Gosiwon, a boarding house or an one-room house-. Qualitative approaching method was used, and quantitative analysis was additionally employed to count keyword found during the interviews. SPSS window version 14.0 was used for the descriptive statistics and the analysis of the items with multi-response analysis. The major findings are as follows; a personal space for each resident with a common kitchen and a bathroom was mostly desired for the unit. Therefore, Two diagrams would be used as examples to explain the new concept of unit planning.

  • A high-resolution seismic survey was conducted on the abandoned tidal flat in Shihwa Lake on the west coast of Korea. A portable vibrator was used as a seismic source and 217 shot gathers with 48-channel system were acquired. F-k filtering, residual static corrections and post-stack frequency filtering are found to be useful for signal enhancement. The overburden is divided into two seismic depositional units. Unit I is deposited in tidal environment characterized by parallel and high continuity reflection pattern. This unit comprises a dry layer (Unit Ia) and a wet layer (Unit Ib) having averagely 5 and 15 meters thick, respectively. Unit II unconformably overlain by Unit I exhibits discontinuity and hummocky reflection pattern, indicating complex channel-fill sediments in estuary. The maximum thickness of this unit is approximately 20 meter. Acoustic basement is considered as Precambrian granitic gneiss occurred in the surrounding area.

  • Purpose: The deformation characteristics induced by non-destructive stresses using piezoelectric transducer(PZT) were analyzed for 3-unit fixed partial dentures manufactured PFM, Everest(CAD/CAM) and Zirkonzahn(copy milling, MAD/MAM) by electron speckle pattern interferometery(ESPI). Methods: The ESPI analysis after loading the restoration with PZT by applying electric voltage of 900mV at the points of 10 mm above the base of the prostheses. Results: PFM and All-Ceramic Everest prostheses showed about 0.1 ${\mu}m$ while that of All- Ceramic Zirkonzahn prostheses showed 0.085 ${\mu}m$, demonstrating that Zirkonzahn displaced less. For PFM and All-Ceramic Zirkonzahn prostheses, the displacements were large at just below the loading point, while generalize displacement was shown over the loading point and weak connector areas for All-Ceramic Everest prostheses. Conclusion: We could find that the deformation characteristics induced by non-destructive stresses using PZT analyzed by ESPI were similar to the fracture strengths evaluated using universal testing machine.

  • The light guide plate (LGP) of LCD-BLU (Liquid Crystal Display-Back Light Unit) is usually manufactured by forming numerous dots by etching process. However, the surface of those etched dots of LGP is very rough due to the characteristics of etching process, so that its light loss is relatively high due to the dispersion of light. Accordingly, there is a limit in raising the luminance of LCD-BLU. In order to overcome the limit of current etched-dot patterned LGP, micro-lens pattern was tested to investigate the possibility of replacing etched pattern in the present study. The micro-lens pattern fabricated by the modified LiGA with thermal reflow process was applied to the optical design of LGP. The attention was paid to the effects of different optical pattern type (i.e. etched dot, micro-lens). Finally, the micro-lens patterned LGP showed better optical qualities than the one made by the etched-dot patterned LGP in luminance.

  • In this paper we examine and compare the computational speeds of three-dimensional (3D) object recognition by use of digital holography based on central unit processing (CPU) and graphic processing unit (GPU) computing. The holographic fringe pattern of a 3D object is obtained using an in-line interferometry setup. The Fourier matched filters are applied to the complex image reconstructed from the holographic fringe pattern using a GPU chip for real-time 3D object recognition. It is shown that the computational speed of the 3D object recognition using GPU computing is significantly faster than that of the CPU computing. To the best of our knowledge, this is the first report on comparisons of the calculation time of the 3D object recognition based on the digital holography with CPU vs GPU computing.

  • This study focuses on finding ECO driving patterns which consider driving safety of the ATO system train and reliability and which optimize efficiency of the driving energy consumption. Research results derived by performing simulation of those 5 models show that the emergency braking which affects safety of passenger and the machinery is minimized, and safe driving speed is maintained by the prohibition of drastic acceleration/deceleration, coasting and constant-speed driving. Therefore if this result is applied to the urban railway train by amending or making ATO program to save energy usage that improve environmental quality, its effects as ECO driving pattern is huge.

  • Grid serves as an auxiliary instrument that explains design logically and objectively when you designing an interior. But grid is unacceptable to the space which is produced by designer who wants to express a design subjectively. Because grid makes usual and standardized space without flexibility. Changing and developing a fundamental unit with modern touch is going to be a way compensate for the weakpoint Also versatile grid unit can support the designer's subjective intention. This study focuses on the limits of Wright's house which show interior space aestheically through grid planing. In this paper Wright's uniqe interior space pattern will be examined through the selection of some of his works specifically the Prairies and Usonians whose transforming is noticable as Wright house and analysis about formation process of grid planning characteristics and spaces is continued. With all this analysis I'm, going to look over Wright's philosophy and pattern that is usually intended by his grid planning.

  • The behavioral-related environmental study for multifamily housing is needed to develop the quality of unit floor plan in terms of user comfort and needs. So, the aim of this study is to find out the living style and housing needs in terms of interaction between the users behavior pattern and orgarnization of physical home space. For the purpose, the field experiments in Pusan, have been carried out with 318 households living in apartments by plan types(2BL, 3BL, 4BL, 5BL) which were classified by number of bedrooms. The dwelling space usage behavior(room use pattern and furniture uasge pattern) and the space adjustment behavior(physical modification of space and preferred space adjustment attitude) were examined and analyzed.
