Recently, due to evolving cloud computing technology, we can easily and transparently utilize both local computing resource and remote computing resource in real life. Especially, enhancing smart device technologies and network infrastructures promote an increase of needs to share files between local smart devices and cloud storages. However, since smart devices have a limited storage space, storing files on cloud storage causes a starvation problem of local storage. It means that users can face a storage-lack problem even a cloud storage service provide a huge file storing space. In this research, we propose a method to manage files between smart devices and cloud storages. Our approach calculate file usage pattern based on recently used date, and then this approach determines local files being migrated. As a result, our approach is sufficient for handling data synchronization between big data storage farm and local thin client which contains limited storage space.

It suggests a closet design for infants in consideration of space utilization, furniture arrangement, and goods storage by integrating a baby's closet and toy chest, which was used for storage of baby's toys and play instrument. For this, it conducted and analyzed data research on the infants' toy chests in the domestic and overseas market and based on such approach, the colors that helped development of infants' cognition and emotion were selected while suggesting familiar animal characters for infants. Without considering separate arrangement of furniture and toy chest within limited space, it allowed space utilization and provided enough storing space. Also, the attached ball casters enabled easy carry of the closet and with this function, it helps infants arrange and store goods by themselves so that making them feel a sense of accomplishment. For effective spatial utilization as well as security of its genuine storage function, the closet and toy chest were combined in this study. Thus, it is believed that development of such multifunctional furniture will suggest the direction of researches on domestic furniture development that are conducted to maximize utilization of residential space for the people living today.

Recently, small satellite industries are rapidly changing. Demand for high performance small satellites is increasing with the expansion of Earth Observation Satellite market. A next-generation small satellites require a higher resolution image storage capacity than before. However, there is a problem that the HW configuration of the existing small satellite image storage device could not meet these requirements. The conventional data storing system uses SDRAM to store image data taken from satellites. When SDRAM is used in small satellite platform of a next generation, there is a problem that the cost of physical space is eight times higher and satellite price is two times higher than NAND Flash. Using the same satellite hardware configuration for next-generation satellites will increase the satellite volume to meet hardware requirements. Additional cost is required for structural design, environmental testing, and satellite launch due to increasing volume. Therefore, in order to construct a low-cost, high-efficiency system. This paper shows a next-generation solid state recorder unit (SSRU) using MRAM and NAND Flash instead of SDRAM. As a result of this research, next generation small satellite retain a storage size and weight and improves the data storage space by 15 times and the storage speed by 4.5 times compare to conventional design. Also reduced energy consumption by 96% compared to SDRAM based storage devices.

In this study, an optimization technique was developed from the application of Allocation Rule. Average Allocation coefficients of the Andong and Imha dam compare constant water supply condition with vary water supply condition that are above the contribute ratio $67\%\~50\%$ the Andong dam in Rule(A)-Rule(C). In the Refill Season, Andong dam water supply contribution is higher than Imha dam at the Control point water supply. In the Allocation analysis results, Rule(A) is calculated storage ratio because Andong dam contribute to Control point larger than Imha dam which Andong dam storage is larger than Imha dam storage. Rule(B) calculated sum of the storage and inflow ratio for Andong dam and Imha dam, as Andong dam contribution is higher than Imha dam. Rule(C) calculated that sum of storage, inflow and water supply is divided average storage ratio, as the best results of the Allocation coefficients and water supply capacity. The results of storage analysis is larger vary water supply condition than constant water supply condition and the results of water supply analysis is larger vary water supply condition than constant water supply condition. Water supply deficit is decrease $30\%$ for vary water supply condition.

Purpose: Recently, the operating unit remodeling compititon has been increasing rapidly in Korea, but there are no design infomation for spatial planning of sterile supply storage. Therefore, the propose of this study is to present area composition of the operating unit after remodeling. Methods: For literature review, the 6 studies and guidelines of operating unit(guidelines in the U.S, Australia, UK and Korea and 2 studies in Korea) conducted surveys and analysis. Room and space composition and zone of operating unit are redefined for this study. For obtaining area, to conduct masuring and calcuating of document of operating unit before and after remodeling in 3 cases. There are some patterns of plan in operaing unit by sterile supply storage. This study derived data for attributes of area composition of sterile supply storage. Results: The results of this study are as follows: First, Reviewing previous studies and Guidelines, for this study the suggested model was 5 zones(Operating zone, Support zone, Patient zone, Staff zone, Circulation zone) and redefined each room and space. Second, For infection control, sterile supply storage was provided to directly accessible to the operating room. Third, According to ralation of operting room and sterile supply storage, there are two types : 'double loaded type' and 'single loded type'. Sterile supply storage shall increase area of ciculation zone. Implications: This study can be used as primary data on remodeling of operating unit. In addition, it suggests that for infect control sterile supply storage is functional area.

This paper discusses dynamic characteristics of a urea-SCR (Selective Catalytic Reduction) system. The urea flow rate to improve NOx conversion efficiency is generally determined by parameters such as catalyst temperature and space velocity. The urea-SCR system was tested in the various engine operating conditions governing the raw NOx emission levels, space velocity. and SCR catalyst temperature. These experiments include cold-transients to determine catalyst light-off temperature and urea flow rate transients. Likewise. ammonia storage dynamics was also investigated. The cold-transient results indicate the light-off temperature of the catalysts used in these experiments was $200-220^{\circ}C$. The ammonia storage and urea flow rate transients all indicate very slow dynamics (on the order of seconds) which presents control challenges for mobile applications. The results presented in this paper should provide an excellent starting point in developing a functional in-vehicle urea-SCR system.

Aiming to solve the problems of high memory access and big storage space and long matching time in the regular expression matching of extended finite automaton (XFA), a new regular expression matching algorithm based on high-efficient finite automaton is presented in this paper. The basic idea of the new algorithm is that some extra judging instruments are added at the starting state in order to reduce any unnecessary transition paths as well as to eliminate any unnecessary state transitions. Consequently, the problems of high memory access consumption and big storage space and long matching time during the regular expression matching process of XFA can be efficiently improved. The simulation results convey that our proposed scheme can lower approximately 40% memory access, save about 45% storage space consumption, and reduce about 12% matching time during the same regular expression matching process compared with XFA, but without degrading the matching quality.
