The purpose of this study was to investigate the stage of concern and use level of early childhood teachers' STEAM, and to find out whether there is a difference in the stage of concern according to individual teachers' variables. The subjects were 242 teachers in charge of 3-5 years old kindergarten and daycare center in G city. The research tool was the stages of concern questionnaire (SoCQ). The collected data were converted to relative intensity by applying percentile conversion chart in the guidelines, and this was expressed as a concern profile graph, and t-test and ANOVA were performed to find out the difference in concern according to teacher's background variables. The research results are as follows. First, the stage of concern in early childhood teachers' STEAM was identified as a critical non-user profile. Second, the stage of concern in the teacher's STEAM was judged as a person who did not use, or was implemented for less than 2 years, and was a non-user or a novice. In addition, it was found that most of the teachers did not receive formal education for STEAM. third. There were differences in the educational background, career, current execution status of teachers, whether or not to take related courses in pre-service teacher education, and whether to plan for future implementation. And there were no differences in the majors and institution types of teachers. Based on these results, a support plan for changing the stage of concern of teachers about STEAM and improving the level of use was suggested.

The process of selecting a small number of representative colors from an image of higher color resolution is called color image quantization. In a color quantization process, it is vet important to determine what colors should be preserve and the others not. In our study, by the idea of an image can be divided into interesting area and uninteresting area, we propose a color quantization method that preserves more colors in the interesting area of an image. We evaluated correctness of extracting interesting area and compared the quality of our method with the others.

A sub-picture slice structure is proposed which can perform the region-of-interest coding effectively, where the subjective quality can be improved by coding the region-of-interest in higher quality than the background region. In addition, the bit allocation mechanism is Proposed where the interval between quantization parameters of the foreground and background region is fixed. And the method to reduce the boundary effect between the foreground and background region is proposed. The foreground region is better protected to the network channel error than the background region. which results in the overall subjective quality improvement in the error prone environments.

In this paper, we propose a news article recommendation system that reflects users' areas of interest and reading habits. Users can select interesting subject then our proposed system displays interesting articles above the other articles. Also the proposed system reflects users' dynamic interests using analyse of user's reading habits. The method of dynamic interest applies the different weight values from users simply clicking and reading entire articles. When users read articles from specific areas, the prosed system increases the weight of these specific areas using XML structure information. Hence users can read their articles of interest with ease.

As a new community forming environment, the blog platform enables sharing of the resources in blogosphere through active information exchange. Many researches have been performed to recommend appropriate resources to users from vast amounts of blog resources. As one of the solutions OSEM defines the knowledge base in the blogosphere with ontology for effectively modeling it. In this paper, we propose a technique of converting the knowledge base into the OWL ontology for sharing it on the semantic web environment. An inference method is then applied to the OWL ontology for recommending interest blog communities. For this aim, a mapping method is offered and then SWRL inference and SPARQL query based on the ontology are employed to extract interest blog communities.

This research is to analyze what kinds of relationships exist between child care teachers' concerns and their role in improving children's creativity and their teaching efficacy. There are two research questions. First, what kind of relationship is shown between child care teacher's concerns and their role in improving children's creativity? Second, what kind of relationship can be shown between child care teacher's concerns and their teaching efficacy? A survey was carried out with 156 public kindergarten teachers in the J region to research these questions. The conclusions are as follows: First, child care teachers' concerns and their role in improving children's creativity had a static correlation in total as well as in part. Second, child care teacher's concerns and their teaching efficacy had a static correlation in total as well as in part. In this study, we have concretely discussed the content and methods of child care teachers' education by analyzing child care teachers' requirements.

This study was conducted on adolescent high school girls who were most interested in their appearance to examine the makeup and cosmetics use of high school girls and to present their correct pre-made cosmetics use training materials. This survey was conducted after the modification and supplementation of the questionnaire. Most high school girls in adolescence begin to wear makeup out of curiosity at the age of 16-17, when they are in their third year of middle school and first year of high school. In other words, high school girls in adolescence begin to wear makeup as the effects of puberty lead to rapid physical development and physical change, and the desire to get attention from reason and others rapidly increase. It can be seen that high school girls who are interested in makeup actively manage their personal appearance as they explore the Internet, TV and other media outlets, copy female celebrities of their own age who appear in the media, and make them look strange.

The service oriented architecture assures flexibility of enterprise application development, so it supports agile reaction to business change. On the other hand, considerable effort is needed to develop a service by combining business and constraint consumes because the entire combination logic should be changed according to the change in business rule. To improve the current method, this paper applied an aspect oriented approach to service system development. In this paper, the rule concern is proposed in addition to the core concern and cross cutting concern of aspect oriented approach. The rule concern is extracted from business rules included in the business processes and services. The rule concern is classified into the process rule aspect and service rule aspect according to the level of the rule. In the proposed approach, system is modularized into the core concern, cross cutting concern and rule concern through separation of concern, and they are maintained independently. Therefore, the adaptability, reusability, and maintainability of a service system will be enhanced.

Video objects of interest play an important role in representing the video content and are useful for improving the performance of video retrieval and compression. The objects of interest may be a main object in describing contents of a video shot or a core object that a video producer wants to represent in the video shot. We know that any object attracting one's eye much in the video shot may not be an object of interest and a non-moving object may be an object of interest as well as a moving one. However it is not easy to define an object of interest clearly, because procedural description of human interest is difficult. In this paper, a set of four filtering conditions for extracting moving objects of interest is suggested, which is defined by considering variation of location, size, and moving pattern of moving objects in a video shot. Non-moving objects of interest are also defined as another set of four extracting conditions that are related to saliency of color/texture, location, size, and occurrence frequency of static objects in a video shot. On a test with 50 video shots, the segmentation method based on the two sets of conditions could extract the moving and non-moving objects of interest chosen manually on accuracy of 84%.
