This paper examines the relationship between children's English proficiency in grade three and English learning environment and experiences before entering elementary school. In English learning environment and experiences, three influences consisting of children, home environment, and environmental influences of English learning are used to find out which influences contributed to children's English proficiency in grade three of elementary school. The result of this study shows that children with high interest in English have higher proficiency in all language skills reading, writing, listening, and speaking than that of children with low interests. For parents' influences, parents' high interests toward their children's English leaning and high monthly income result in children's high English proficiency. For English environmental influences, children who start at the early age and continue studying English have higher English proficiency.

Abstract should be in English. The leaning angle optimization of turbine blade using the genetic algorithm was conducted in this paper. The calculation CFD technique was based upon the Diagonalized Alternating Directional Implicit scheme(DADI) with algebraic turbulencemodeling. The leaning angle of VKI turbine blade was represented using B-spline curve. The control points are the design variable. Genetic algorithm was taken into account as an optimization tool. The objective was to minimize the total pressure loss. The optimized final geometry shows the better aerodynamic performance compared with the initial turbine blade.

우리나라에는 영어 학습을 위한 수많은 도구들이 있다. 특히, 최근 스마트폰의 출현으로 영어 학습을 위한 어플리케이션 개발이 활발하다. 그러나 대부분 영어단어를 단순히 암기하는 방법에 관한 것으로 텍스트 분석에 대한 어플리케이션은 부재하다. 본 논문에서는 사용자가 텍스트를 입력하면 단어가 갖고 있는 희소성에 따라 온톨로지 기반으로 분석되어져서 등급을 매기는 어플리케이션 시스템을 제안한다. 결과물은 파일 시스템과 데이터베이스에 저장되어 사용자는 텍스트의 희소성에 따라 선택한 텍스트를 읽음으로서 사용자의 눈높이에 맞게 신속하고 효율적인 어휘획득 능력을 갖게 된다.

Recent technological advancements, along with an increase in mobile Internet access, have spurred on significant developments in the production of e-textbooks. This case study explored the affordances of an iPad e-textbook through teacher and student experiences in English lessons using observation and interviews. The results showed that English learners and teacher benefited from handy and quick web access and the all-in-one features of the e-textbook (dictionary, hyperlinks, and note-taking functions). However, information oversupply by the e-textbook confused students' learning and both students and teacher pointed out technical difficulties in using the e-textbook. In order to implement English pedagogy with technologies such as iPad e-textbooks, teachers should be equipped with the relevant technical skills and content knowledge in order to assist them in becoming autonomous learners in the digital classroom.

This study selected brand logos of six South Korean and Chinese banks including KB, IBK, SH, ICBC, ABC, and SISB, conducted Eye Tracking experiment among 36 South Korean and Chinese university students(Nine male and female students, respectively), and analyzed the difference of visual attention of consumers on bank brand logo, symbol, Korean/Chinese character logo types as well as the difference of visual attention of these consumers on English logo types. Results were represented by using statistics and visualization including GAZEPLOT, HEATMAP, and visual expression. Results showed that most generally gazed logo types more often and longer than symbols when they watched bank brand logos. A slight difference was observed between both groups in terms of gazing English logo types. This study has a implication that it proposed the possibility of drawing quantitative and reliable outcomes by utilizing eye tracking device and approaching in an objective standpoint beyond a methodological aspect on bank brand logo primarily leaning over the analysis of case research or design development. Moreover, findings are expected to serve as basic data for proposing the direction of special bank brand logo design and marketing strategies.

As information society matures to an even higher level and as information technology becomes a necessity to our everyday lives, the needs to develop, support and satisfy personal and social needs without the limitation of time, space, and location have become a vital point to everyday lives. Smartphone users are increasing at a staggering rate but the research on mobile-Learning model and the implementation of m-Learning scenario are still behind the needs of the users. Therefore, this paper focuses on the design of 'repeatable and short-spanned m-Learning model' to meet the needs of the learners who are on the go and on the move with their smartphones. Smartphone users frequently reach out for their phones but compare to the frequencies, the actual span of time they spend per use are relatively and surprisingly short. One way to understand this phenomenon is that the users tend to immediately replace their smartphones with laptops or desktops whenever they are available. A leaning model was needed to reflect this short and frequent use, a use that is solely based on the smartphone environment. This proposed learning model first defines this particular setting and implements the model to real smartphone users over an 8 week period. To understand whether different learning backgrounds can influence this model, different schools with online and offline learning channels participated in the experiment. User survey was conducted after the experiment to get a better understanding of the smartphone users. Pretest and posttest were conducted before and after the experiment and the data were validated and analyzed using SPSS version 18.0 for PC. Preliminary descriptive statistics, multiple regression and cross validation was conducted for the analysis. The results showed that the proposed English Listening and Comprehension Mobile Digital Textbook (ELCMDT) had a positive effect on the learners in general and was more effective for learners who were already experienced with online learning.

Human beings and chimpanzees are very much alike. and scientists say there is only 1% difference between them. Contrary to our expectations, the difference lies not in brains but in tracheas ( windpipes ). Those of human beings are bigger and longer than those of chimpanzees. Thu means more air is inspired and expired as breath. About breath there are interesting descriptions in the Bible. In the Genesis it says God made a man out of soil and breathed life-giving breath into his nostrils and the man began to live. In other part it says life exists between incoming breath and outgoing breath. Thus breath plays key role is our life. In Hebrew and Greek, breath and spirit are the same words. In Hebrew it is ‘Luahf’ and in Greek, ‘Pneuma’ With breath and mouth organs human beings produced voice, and with haritage and through leaning we train our voice to reach the level of language which convey our culture. My contention is to realize the gift of voice and train it so that it can perform proper function as a tool of conveying our thought and culture. This is a kind of practice of speech and it may be called speechology. It includes the following practical methods: 1. Try to read aloud. 2. Encourage recitation, 3. Make public speaking as possible. 4. Learn theories of phonetics; such as about pronunciation, accent, intonation, prominence, assimilation and so on.
