This study investigated the integrated effects of family, school, internet, and mass culture factors on the identity formation of adolescents. Specifically, the purposes of this study were to categorize adolescents into groups by what they do during the time except the life in school and to investigate differences among the groups regarding the identity information(body image, self-esteem, self-identity) and the influences of environmental factors on identity formation of adolescent. The study distributed questionnaires to middle and high school adolescents of five representative cities in South Korea. The total respondents were 2240(960 from Seoul/Kyongki, and 320 each from Taegu, Pusan, Kwangju, and Taejon). The response rate was 98.7%. The data were analyzed by factor analysis, cluster analysis, ANOVA, Duncan test, and multiple regression. The results showed that Korean adolescents were segmented into five groups : TV preference group, computer preference group, friends and family involvement group, homework and study preference group, and study institute involvement group). The five groups were significantly different in regard to body image pursuit, self-esteem, and self-identity. The body image pursuit, self-esteem, and self-identity of adolescents were significantly different in regard to each environmental factors, in each adolescent group.

Drop size is one of the most important parameters which are control the performance of the engine using liquid fuel/oxidizer and drop formation is mainly controlled by aerodynamic force caused by ambient gas. Because of this, empirical data and correlation acquired under standard ambient condition are not valid. So experiments under high ambient pressure condition to measure the drop size using image processing method And find the empirical correlation between SMD and chamber pressure(density), injection velocity.

The purpose of this study was to investigate the meaning structure of Korean costume image in contemporary Korean fashion design expressed beauty of traditional dress. This study compared Korean and American regarding the evaluation of Korean costume image. The result was as follows; 1. The constructing factors of Korean costume image were found out as elegance, simplicity, neatness, femineity, looseness. (total variance; 62%) 2. The visual evaluation between Korean and American were sinificantly different regarding 5 factors. 3. Korean costume design were classified 4 clusters. Korean traditional fabrics and colors were commonly used in the 4 clusters. Difference of design were found in the structure of form. Formation of Korean costume image were influenced by silhouette and pattern of fabric. 4. Image of 'Would like to purchase' were influenced by image of taste.

The demand for a real-time image surveillance system using network camera server is increasing as the network infra has been grown and digital video compression techniques have been developed. The image surveillance system using network camera server has several merits compared to existing real-time image surveillance system using CCTV. It would be more convenient if wireless realtime image transmission were possible. In this paper, a bluetooth module is designed and implemented for a real-time image surveillance system to send and receive informations wirelessly. It may simplify the system development procedures and increase the productivity by low power consumption, low cost, and simple wireless installation. A scatter-net formation is proposed using dynamic and distributed algorithm so that the network connection is reliable.

In the integral imaging system for 3D display, we have investigated the image distortions, such as duplication and omission, which are presented in the reconstructed image. We have also discussed the quantitative condition which minimizes the distortion, with several fundamental variables. In addition, we present the experimental results which support the quantitative analysis of the distortion.

A modeling of vision based robot formation control system using fuzzy logic controller and extended Kalman filter is presented in this paper. The main problems affecting formation controls using fuzzy logic controller and vision based robots are: a robot's position in a formation need to be maintained, how to develop the membership function in order to obtain the optimal fuzzy system control that has the ability to do the formation control and the noise coming from camera process changes the position of references view. In order to handle these problems, we propose a fuzzy logic controller system equipped with a dynamic output membership function that controls the speed of the robot wheels to handle the maintenance position in formation. The output membership function changes over time based on changes in input at time t-1 to t. The noises appearing in image processing change the virtual target point positions are handled by Extended Kalman filter. The virtual target positions are established in order to define the formations. The virtual target point positions can be changed at any time in accordance with the desired formation. These algorithms have been validated through simulation. The simulations confirm that the follower robots reach their target point in a short time and are able to maintain their position in the formation although the noises change the target point positions.

The trend that an apartment is regarded as not only a substantial property called 'residence' but also 'means of self-expression' to consumers is increasing in the present housing marketing, and thus, the apartment brand image is settling down as an important field of marketing management. Therefore, the present study aimed to verify difference of brand attitude according to consentaneity between an image of a housing brand and self-image of consumers to propose one kind of direction of strategies for formation of a differentiated brand image. As a result of a research, the trend that consumers show more positive attitude on a brand apartment having a brand image closer to an ideal self-image was analyzed to exist even if it is weak, so it was confirmed that the consentaneity between a brand image and a self-image of housing products can become a variable having some influence on brand attitude. The survey method understood a brand image, a self-image and brand attitude by using a Likert's 5-point scale on apartment brands of upper three companies according to a study result of a national brand competitiveness index(NBCI) and understood self-consentaneity by using a distance measurement model of self-consentaneity of Sirgy(1982). The questionnaire for the present research was carried out by surveying students of D university and the PASW program was used for statistical data analysis.
