For the efficient searching and browsing of digital video, it is essential to extract the internal structure of the video contents. As an example, a news video consists of several sections such as politics, economics, sports and others, and also each section consists of individual topics. With this information in hand, users can ore easily access the required video frames. This paper addresses the problem of automatic shot boundary detection and selection of representative frames (R-frames), which are the essential step in recognizing the internal structure of video contents. In the shot boundary detection, a new algorithm that have dual detectors which are designed specifically for the abrupt boundaries (cuts) and gradually changing bounaries respectively is proposed. Compared to the existing 미algorithms that mostly have tried to detect both types by a single mechanism, the proposed algorithm is proved to be more robust and accurate. Also in the problem of R-frame selection, simple mechanical approaches such as selecting one frame every other second have been adopted. However this approach often selects too many R-frames in static short, while drops important frames in dynamic shots. To improve the selection mechanism, a new R-frame selection algorithm that uses motion information extracted from pixel difference is proposed.

Young children need continuous care and fostering by their family. They help children organize and develop their potential and grow to be and integrated individuals. Children are influenced by then family at first and continuously when they grow up and develop their capability. Especially, mothers spend a lot of time with time to their children, encourage children's growth, give advice, and do their best to take care of their children. The ethnographic study is to understand the patterns and rules of human behaviors. This study utilized this method in order to interpret the maternal health promoting behaviors for their children. The data were collected through the participant observation and direct interview for about 18 months in P city. The participants were 7 mothers, from 32 to 37 years old. They have children of ages 3 to 10 and 1 or 2 children in total. The data were analyzed through the Spradley's Ethnographic method and the results were summarized as follows : The viewpoints which influence maternal health promoting behaviors include “having childlike appearance”. “having childlike character”, “living without illness”, and “eating well”. The maternal health promoting behaviors for children are classified as “adapting to nature”, “supporting of ability”, “sharing with the family”, “training”, and “praying”. The adapting behaviors include “recognizing child's innate character”, “controlling maternal desires”, “preparing natural food”, which includes breast feeding. The supporting behaviors include “recognizing childlikeness”, “empowering”, and “restricting certain actions to preventing accidents”. In order to promote child's health, it is essential to promote mother's health first of all. The sharing with the family includes “promoting family concord or acquaintanceships concord” and “adapting to circumstances beyond family”. The training behaviors include “forming good habits” and “having good moral value”. It is very important to form good habits in childhood. The praying behavior include “waiting for opportunities” and “endeavoring activity to promote child's health”. The above 5 behaviors by mothers appeared to be able to promote children's health. The results of this study can be utilized to provide the basic information necessary to develop the patterns of maternal health promoting behaviors consistent with our culture and can contribute us develop the body of knowledge about the maternal health promotion for children in nursing.

Recognizing a limits on quantitative evaluation of cultural contents' and for its betterment, study aims developing a qualitative evaluation model. For this study, Reception Theory, Semiotics and Psychology were derived for epistemological dimension to contemplate culture contents' essential attribute. To be concrete, cultural contents was examined as experiential products, emotional products, rememberable products and texts. Also, codes of fun, emotion and culture were discussed as intrinsic attributes for cultural contents and how those attributes were expressed or composed in cultural contents was discussed as well. Evaluation items were extracted based on final discussion at the epistemic level, set up the final evaluation model by taking experts' advices on each items. With all those outcomes, qualitative evaluation model for cultural contents was developed. For the importance of each index in the model, priority was granted by weighting on each index. Lastly, evaluation scale was developed for each index. The culture contents' evaluation model developed in study is meaningful not only in drawing qualitative evaluation items of video(image) contents and developing the index and model for the first time, but also its possibility of wide use for other genres.

Fast and accurate signature extraction is essential to improve the performance of the payload signature-based traffic analysis methods. However the slow manual process in extracting signatures make difficult to deal with the rapidly changing application in current Internet environment. Therefore, in this paper we propose a system automatically generating signatures from ground-truth traffic data. In addition, we improve the efficiency of signature extraction by recognizing the application protocol using a protocol filters and generating signatures automatically according to the application-specific protocol contents. In order to verify the validity of the system proposed in this paper, we compared the signatures automatically generated from our system with the signatures manually created for a few popular applications.

The database for driving patterns can be utilized in various system such as automatic driving system, driver safety system, and it can be helpful to monitor driving style. Therefore, we propose a driving pattern recognition system in which the sensor streams from a smartphone are recorded and used for recognizing driving events. In this paper we focus on the driving pattern recognition that is an essential and preliminary step of driving style recognition. We divide input sensor streams into 7 driving patterns such as, Left-turn(L), U-turn(U), Right-turn(R), Rapid-Braking(RB), Quick-Start(QS), Rapid-Acceleration (RA), Speed-Bump(SB). To classify driving patterns, first, a preprocessing step for data smoothing is followed by an event detection step. Last the detected events are classified by DTW(Dynamic Time Warping) algorithm. For assisting drivers we provide the classified pattern with the corresponding video stream which is recorded with its sensor stream. The proposed system will play an essential role in the safety driving system or driving monitoring system.

This study is focused on developing a software that predicts the temperature distribution and infrared Emission from 30 objects considering the solar radiation through the atmosphere. The solar radiation through the atmosphere is modeled by using the well-known LOWTRAN7 code. Surface temperature information is essential for generating the infrared scene of the object. Predictions of the transient surface temperature and the infrared emission from a naval ship by using the software developed here show fairly good results by representing the typical temperature and emitted radiance distributions expected for the naval ship considered in mid latitude. Emissivity of each material is appeared to be an important parameter for recognizing the target in Infrared band region. The numerical results also show that the low emissivity surface on the heat source can be helpful in reducing the IR image contrast as compared to the background sea.
