Proportionately with a rapid development of mobile instrument technology, the number of mobile contents utilizing computing environment's graphic technology or image processing is increasing. In this paper, I designed a middleware which supports facial detection and recognition system based WIPI(Wireless Internet Platform for Interoperability), the Korean standard mobile platform. The facial recognition middleware introduced the object oriented concepts, to apply to recognition security and other contents by using mobile camera. This can reduce the development time and cost by dividing process while developing software. Therefore, it would be applied to content security or technology transfer with other company. Facial recognition middleware system is composed of face detection module and face recognition module, and proposes the application contents design method based on WIPI platform.

This study was conducted to investigate the pre-service teacher's perception of the possibility of using smartphones in the classroom, moreover, to confirm the policy related to using smartphones in schools. For the objectives, this study, firstly, investigated the pre-service teacher's awareness of having cellphones in the classroom, secondly, analyzed the pre-service teacher's opinion of using smartphones for educational objectives and elements for those investigated objectives, finally, investigated the school policy for educational objectives of using smartphones. The participants of this study were 146 pre-service teachers among three universities in Seoul. The results showed that the pre-service teachers opposed using cellphones in the classroom. Next, it was found that most of them had smartphones and they knew how to use them effectively. For the aspects of educational use of smartphones, they recognized that smartphones could be used as a smart educational tool, an efficient teaching and learning tool, and an assistant tool for teaching and learning. In order to use smartphones for the investigated educational tools, the learning contents, the ways of teaching and learning, and the technical support of the school should be prepared. Finally, the pre-service teachers thought that the school policy should be changed in order to use smartphones for educational objectives, and the school policy with regard to using smartphones in the classroom should be decided by the teachers. Most of all, for the educational use of smartphones, the pre-service teachers believed that the change of the students' perception was the most significant.

In order to understand how to increase the use of virtual training content at K University's online lifelong education institute, this study examined the use experience, content recognition, field practice replacement, and requirements, focusing on the examples of operating institutions. To this end, 12 institutions that operated virtual training contents distributed by the K University Online Lifelong Education Center in 2020 were selected for in-depth interviews and qualitative analysis was conducted on the interviews of 11 institutions. As a result of the analysis, first, the experience of using the contents of the virtual training operating institution was aimed at changing the educational environment, supplementing theoretical learning, and improving the sense of practice. Second, according to a survey on the recognition of virtual training content, if the importance and utilization of the content are high, it can be replaced by on-site practice in non-face-to-face classes, such as experiences of facilities and equipment, attracting interest and attention. Third, in many cases, the perception of replacement for field practice is not unreasonable to use as a pre-training material for field practice, but it is difficult to replace field practice. Fourth, content quality improvements can be summarized as content quality improvement, content access and manipulation improvement, dedicated device development, training for instructors, and curriculum systematization. Fifth, institutional requirements include improving the quality of virtual training content itself, equipment support, curriculum systemization and characterization, systematic curriculum and detailed content sharing, detailed guidance on using virtual training content, introducing how to use content, and recruiting instructors. This study is meaningful in that it sought ways to improve the utilization of virtual training content based on the perception of virtual training content operating institutions.

The purpose of this study is to analyze the structural relationship among the usefulness, ease of use, use intention, and learning utilization of smart learning devices recognized by college students. In order to achieve this, the following problems were addressed: first, how do college students' recognition of ease and usefulness of smart learning devices? second, how do college students' recognition of ease and learning utilization? third, what mediating effects od use of smart learning devices and learning utilization? As for the research method, a survey of 350 students who participated in smart learning was conducted to conduct a home review, confirmatory factor analysis, and bootsrapping for structural equation estimation and mediating analysis. As a result of the analysis on this, first, it was found that the usefulness and ease of smart learning devices recognized by college students had an effect on the intention of use. Second, it was found that the perception of the usefulness and ease of smart devices perceived by college students had an effect on the use of smart learning device learning. Third, it was found that the intention to use smart devices perceived by college students mediated the relationship between usefulness and learning utilization, and it was found that it mediated the relationship between ease and learning utilization. The implications are that instructors can recognize and utilize the intention of using smart learning devices properly by allowing college students to recognize the usefulness and ease of using smart learning devices in the classroom, thereby increasing the learning utilization of smart learning devices in class. In addition, efforts are needed to enable college students to recognize the usefulness of smart devices and to expand the use of learning.

Objective: The purpose of the study was to investigate the current status of early childhood teachers' picture book reading activities and their knowledge and utilization of the picture book peritexts. Methods: The subjects were 276 early childhood teachers in Seoul metropolitan area. The survey was conducted to investigate early childhood teachers' current status of picture book reading activities as well as their knowledge and utilization of picture book peritexts. The collected data were analyzed using SPSS Statistics 21.0 program to analyze descriptive statistics such as frequency and percentage. Results: As results, most early childhood teachers recognized that reading picture books to young children was very important and responded that the purpose of reading picture books was to develop children's imagination and creativity. In terms of early childhood teachers' knowledge on 12 peritexts, some peritexts such as 'title', 'cover' and 'title page' were recognized at high level but other peritexts such as typography and layout were at low level. In addition, early childhood teachers' utilization level of peritexts were shown as relatively low compared to their knowledge level. Conclusion/Implications: The study results imply that early childhood teachers need to be informed of the concepts of picture book peritexts and encouraged to utilize peritexts while reading picture books to young children.

The purpose of this research is to enhance document recognition system which is essential for developing full-text retrieval system of the document image data stored in the digital library of a public institution. To achieve this purpose, the main tasks of this research are: 1) analyzing the document image data and then developing its image preprocessing technology and document structure analysis one, 2) building its specialized knowledge base consisting of document layout and property, character model and word dictionary, respectively. In addition, developing the management tool of this knowledge base, the document recognition system is able to handle the various types of the document image data. Currently, we developed the prototype system of document recognition which is combined with the specialized knowledge base and the library of document structure analysis, respectively, adapted for the document image data housed in National Archives of Korea. With the results of this research, we plan to build up the test-bed and estimate the performance of document recognition system to maximize the utilization of full-text retrieval system.
