The purposes of this study were to investigate actual use, design preference, and purchasing behaviors of bedding among married women in their 30s to 60s, and to determine the differences by age groups on these variables. The subjects were 623 married women and the research method was survey. The data were analyzed by descriptive statistics, cross tab analysis, multiple response analysis, ANOVA, and Duncan's multiple range test, using SPSS program. The results were as follows. First, on the actual use of bedding, the possession quantity of the bed cover and mattress was 2~4 while bedclothes and pillow was 7~8. The period of use of bedding was about 2~4 years and the frequency of washing was about 2~3 times a month. Second, married women generally preferred white and pastel tones, floral patterns, cotton fabrics, and a clean and comfortable image on bedding designs. Third, on the purchasing behaviors of bedding, married women considered functional damage and health & sanitary aspects as important purchase purposes. The most important selection criterion was fabric. Price, tactility, functionality, and manageability were also important criteria. Married women generally used the internet and store displays as important information sources, and considered bedding specialty stores as important purchase places. They generally spent about 200,000~300,000 won a year to purchase bedding. Fourth, the actual use, design preference, and purchasing behaviors of bedding showed many differences by age group. Therefore, it is needed to establish product development and marketing strategy of bedding, considering customers'age variable.

When a USB digital camera is used for PC video-conference applications, motion picture data need to be transferred to the PC through the USB port. Due to the mismatch between the data rates of the USB and the motion picture, data compression should be performed before the transmission from the USB. While many motion picture compression algorithms require large intermediate memory space, the JPEG algorithm does not need to store an entire frame for the compression. Instead, a relatively small buffer is required at the input of the JPEG compression engine to resolve the inconsistency between the orders of the inputted data and the consumed data. Data reordering can be easily implemented using a double buffering scheme, which still requires a considerable size of memory. In this paper, a novel memory management scheme is proposed to avoid the double buffering. The proposed memory architecture requires a small amount of memory and a simple address generation scheme, resulting in overall cost reduction.

Recently, the necessity of systems which effectively store and retrieve video data has increased. Conventional video retrieval systems retrieve data using menus or text based keywords. Due to the lack of information, many video clips are simultaneously searched, and the user must have a certain level of knowledge to utilize the system. In this paper, we suggest a natural language based conversational video retrieval system that reflects users' intentions and includes more information than keyword based queries. This system can also retrieve from events or people to their movements. First, an event database is constructed based on meta-data which are generated by domain analysis for collected video in an office environment. Then, a script database is also constructed based on the query pre-processing and analysis. From that, a method to retrieve a video through a matching technique between natural language queries and answers is suggested and validated through performance and process evaluation for 10 users The natural language based retrieval system has shown its better efficiency in performance and user satisfaction than the menu based retrieval system.

Recently, protection of personal information is getting more important. Many countries have legislated about the protection of personal information. Now, the protection of relevant personal information is required not for a simple image of enterprises but law obligation. Most databases in enterprises used to store customers' names, addresses and credit card numbers with no exceptions. The personal information about a person is sensitive, and this asset is strategic. Therefore, most enterprises make an effort to preserve personal information safely. If someone, however, hacks password information of DBMS manager, no one can trust this system. Therefore, encryption is required based in order to protect data in the database. Because of database encryption, however, it is the problem of database performance in terms of computation time and the limited SQL query. Thus, we proposed an efficient query method to solve the problem of encrypted data in this paper.

Generally, multi-dimensional data such as image and spatial data require large amount of storage space. There is a limit to store and manage those large amount of data in single workstation. If we manage the data on parallel computing environment which is being actively researched these days, we can get highly improved performance. In this paper, we propose a parallel high-dimensional index structure that exploits the parallelism of the parallel computing environment. The proposed index structure is nP(processor)-n$\times$mD(disk) architecture which is the hybrid type of nP-nD and lP-nD. Its node structure increases fan-out and reduces the height of a index tree. Also, A range search algorithm that maximizes I/O parallelism is devised, and it is applied to K-nearest neighbor queries. Through various experiments, it is shown that the proposed method outperforms other parallel index structures.

Car running data collected from the vehicle is a native image data and sensing data of it. Hence, it can be used as a set of objective data based on which events that took place outside the car can be analyzed and determined. In this paper, we designed and implemented a emergency situation detection system to sense, store, and analyze signals related to car movements, driver's various operation states, collision pulse, etc when a car collision accident occurs on the actual road by sensing and analyzing the car movements and driver's operation status. The suggested system provides information on the driver's reaction right before the collision, operation state of the vehicle, and physical movement. The collected and analyzed data on vehicle running can be utilized to clarify the cause of a collision accident and to handle it in a just manner. Besides, it can contribute to grasping and correcting wrong driving habits of the driver and to saving.
