High School and College Bridge Program for high school students to learn about specialty training through Mentors with high tech equipment before college admissions has been established. In this study we further developed the previous research experience in 2013 to mentoring program. According to this program, we developed the team learning program and then conducted analytic study on the second year achievement. They became mentees and undergraduate students or graduate course student were mentors. High school students learned how to solve problems by themselves under the mentoring education. The mentees had higher satisfaction in lecture and interest increasing factors at first part of the program. In second part, they showed more satisfaction in new knowledges and recommendation factors. The relationship and intimacy have grown through interaction between mentors and mentees during the team learning. The high school and college bridge program would have significant meaning to develope a customized program for high school students through continuous study.

This study examined the job competence of the staff at the center for teaching and learning(CTL) in university and to find out the level of job competence, which has been asked to the staff of the CTL. For that, the factor of the job competence, which is required of the staff of the CTL, was inquired through a literature review. Based on the job competence, this study examined the required job competence of the staff in Daejeon city and Chungnam province. The result suggests that the job competence required of staff are the basic job competence, planning-analysis job competence, management job competence for the project, and evaluation job competence. The first factor in basic job competence is the attitude to change and innovation. In the planning-analysis job competence, the first factor is an analysis and consultation of instruction. In managing the job competence for the project, the first factor is the management of human resources, and the first factor in evaluating the job competence is an evaluation of the effectiveness of the media. Therefore, to revitalize the CTL, there is a need to organize an expert pool, plan and support program that is suitable for professional development.

As Chinese characters occupies more than 70% of words we currently use, the education of Chinese characters is becoming important day by day to accurately deliver the meaning of words in our language life. In recent, there are increasing concerns on writing Chinese characters correctly, especially the order of stroke, as well as memorizing the meaning and the sound of a character. Books and Internet contents on Chinese character writing is emerging. However, currently available Internet media on the Chinese characters education only illuminates recitation and interpretation. Even though some books contain the chapter concerning the order of stroke of a character, those only force simple repetitions. In this paper, we propose a design and implementation of teaming system for writing of Chinese character based on web which enables the user-directed teaming. Using the system, a user can manage the status of learning by oneself. Additionally, we can enhance the efficiency of learning by making users understood the correct reading and writing in Chinese character education.

The purpose of this study was to examine the awareness of elementary teachers about educational technology. Educational technology that is embodied at school was the form of "systemic structure" whose components are complex and exert close mutual influence on one another, rather than of "systemic assembly" that relationship of components were well controlled. A qualitative epistemological method was used to look into educational technology instead of existing empirical ones. Metaphor analysis was utilized among various qualitative research methods to find out what elementary teachers thought of educational technology. Six elementary teachers were asked to draw a picture to describe what came into their mind when they heard term of "educational technology," and they were interviewed in depth to check what their pictures meant. As a result, elementary teachers expressed their point of views about educational technology as "a scientific, technical and systemized instrument to stir up the learning interest and joy of students," "an action to mechanically fit together every part of education(curriculum)," "educational technology as a teaching and learning method," and "an integrated and overall system." This finding seemed to have something to do with media theory, teaching and learning theory and system theory that have been used in educational technology. This study was expected to be significance in that it investigated the way of looking at educational technology in the field, and confirmed the close relationship between theory and practice, and finally provided an opportunity to reflect on the ontological nature and epistemological method of educational technology.

IoT(Internet of Things) is applied to technologies such as agriculture and dairy farming, making it possible to cultivate crops easily and easily in cities.In particular, IoT technology that intelligently judge and control the growth environment of cultivated crops in the agricultural field is being developed. In this paper, we propose a method of predicting the growth environment of plants by learning the moisture supply cycle of plants using the intelligent object internet. The proposed system finds the moisture level of the soil moisture by mapping learning and finds the rules that require moisture supply based on the measured moisture level. Based on these rules, we predicted the moisture supply cycle and output it using media, so that it is convenient for users to use. In addition, in order to reduce the error of the value measured by the sensor, the information of each plant is exchanged with each other, so that the accuracy of the prediction is improved while compensating the value when there is an error. In order to evaluate the performance of the growth environment prediction system, the experiment was conducted in summer and winter and it was verified that the accuracy was high.

In social media, when posting a post, tag information of an image is generally used because the search is mainly performed using a tag. Users want to expose the post to many people by attaching the tag to the post. Also, the user has trouble posting the tag to be tagged along with the post, and posts that have not been tagged are also posted. In this paper, we propose a method to find an image similar to the input image, extract the label attached to the image, find the posts on instagram, where the label exists as a tag, and recommend other tags in the post. In the proposed method, the label is extracted from the image through the model of the convolutional neural network (CNN) deep learning technique, and the instagram is crawled with the extracted label to sort and recommended tags other than the label. We can see that it is easy to post an image using the recommended tag, increase the exposure of the search, and derive high accuracy due to fewer search errors.

Preference for music is determined by a variety of factors, and identifying characteristics that reflect specific factors is important for music recommendations. In this paper, we propose a method to extract the singing voice related music features reflecting various musical characteristics by using a model learned for singer identification. The model can be trained using a music source containing a background accompaniment, but it may provide degraded singer identification performance. In order to mitigate this problem, this study performs a preliminary work to separate the background accompaniment, and creates a data set composed of separated vocals by using the proven model structure that appeared in SiSEC, Signal Separation and Evaluation Campaign. Finally, we use the separated vocals to discover the singing voice related music features that reflect the singer's voice. We compare the effects of source separation against existing methods that use music source without source separation.
