The study was aimed at verifying the effectiveness of Book-Coding reading education as a reader activity of older elementary school children at a time when high-dimensional thinking abilities were formed. To this end, 30 fifth-grade children of N Elementary School in N-si, Gyeonggi-do, comprised of 15 students from a reading education program using Book-Coding, and 15 students from a reading comprehension program, and applied the reading education program over a total of 12 sessions. The main results of the study are summarized as follows. First, when the effects of the convergence reading education program using Book-Coding on the logical thinking ability of the students in the upper grades in the elementary school were analyzed, all the six sub-factors of logical thinking ability, that is, conservation logic, proportional logic, variable controlling logic, probabilistic logic, correlational inference logic, and combinational logic, were proved to have statistically more meaningful difference than the group writing a book report. Second, the analysis result of the influence of the convergence reading education program using Book-Coding on the creativity of the students in the upper grades of the elementary school showed that all the 13 elements of curiosity, persistence, effectiveness, independence, adventurousness, openness, knowledge, imagination, originality, sensitivity, fluency, flexibility, and accuracy were statistically meaningfully different compared to the book report group. Third, when it was analyzed how the convergence reading education program using Book-Coding affected the creative personality of the elementary school students, all the six factors of curiosity, task commitment, independence, awareness of risk, and openness of thinking, and aesthetics were found out to have a statistically more meaningful difference than the group that wrote a book report.

There are a number of voice analysis programs around the world. Domestic voice analysis is performed by relying heavily on specific commercial program. We intend to develop coding for voice analysis using Praat and apply it to clinical practice. This study consisted of Experiment 1 and Experiment 2. Experiment 1 was the development of automated voice analysis coding based on Praat. The coding was largely divided into a recording, an analysis, and a storage section. Experiment 2 was applied to the voice analysis of 2 male patients pre- and post-operation with this coding. The analysis parameters of this coding provided 26 parameters for vowel /a/, nine parameters for sentence analysis, and a total of 4 parameters for voice range profile analysis. In two male patients, the pitch and the intensity increased, the voice quality improved, and the sentence length decreased after surgery. The coding was well made, so the output was good in real time. The code is automated as much as possible to block manual errors and increases convenience and efficiency by generating the result sheet in real time.

The purpose of this study is to identify the current state of coding education for children and to propose a new 'play-oriented' educational content to keep up with the problems of education in line with the revision process of the 4th Industrial Revolution. As a research method, we investigated and analyzed the case of the Korean early childhood coding education program, and then suggested the direction of the future infant coding education and suggested a new play area for children. Case analysis shows that current coding education places many restrictions on children's activities. So we propose a coding education space as a 'playing space' where children can actively play. Because the space is used, emotional education is possible because it can stimulate senses such as vision, touch and smell. In addition, this study is expected to cultivate not only spatial comprehension, but also imagination, creativity and cooperation. In future research, we will study the characteristics and technical process of children in-depth to help develop early childhood education.

In recent years the demand for digital video and image communications has been increased tremendously. On the other hand, video communications requires very much bandwidth in comparison with other information types such as text and data. Thus to adapt with the bandwidth-limited channels, especially wireless channels, video source must be compressed extremely. A new video coding standard namely H.26L is being developed by Joint Video Team (JVT). In this paper performance of H.26L is analyzed in an AWGN environment.

최근 포유동물의 유전체에는 알려진 것보다 훨씬 많은 RNA 전사체가 발현되고 있음이 밝혀지고 있으며, 그 중에 많은 부분이 non-coding RNA로 알려지고 있다. 세포 내에서 non-coding RNA의 기능이 훨씬 다양해지고, 중요해지고 있는 상황에서 새로운 non-coding RNA를 정의하고, 탐색하는 것은 가장 시급한 과제이다. 본 연구에서는 이전 연구에서 RNA 공통 구조 학습을 위해 제안되었던, esRCSG (evolutionary search for RNA common-structural grammar) 알고리즘의 성능 향상을 위해, committee machine을 도입한다. Committee machine은 마지막 세대에서 최적화된 RNA 공통 구조 기술자 (RCSD)와 차상위로 최적화된 기술자들 중 양성데이터와 음성데이터의 치역을 합쳤을 때 특이도는 거의 변화가 없으면서 민감도의 증가가 가장 큰 기술자들의 집합이다. Committee machine은 특히 family type의 서열의 가진 특정 ncRNA에서 좋은 성능 향상을 보인다. microRNA를 이용한 성능평가에서 특이도의 변화가 거의 없이 민감도의 성능이 약 1.5배 향상되는 결과를 보였다. 이러한 특이도와 민감도가 높은 기술자를 이용함으로써 새로운 non-coding RNA를 예측하는 것을 약속할 수 있을 것이다.
