We investigated the proper display environment for japanese electronic character reading lessons through the experiment with a projection TV and a computer. For the purpose of finding out the effect of prior learning activities at the context of authentic Japanese text orthography, which includes dual notation, words spacing, etc., we also made an experiment on comprehending the web documents which are extracted from japanese web sites. From the experimental results, we acquired a conclusion that two approaches are needed to enhance the ability of comprehending Japanese web documents which is newly added to the 7th curriculum revision. For short-term approach, we need to utilize Japanese web documents as learning materials. For long-term approach, we have to reconsider whether the orthography of the current Japanese textbooks is suitable or not.

본 논문에서는 Google에서 지원하는 오픈소스인 Tesseract-OCR을 이용한 문자/음성 인식 및 번역 앱에 대해 제안한다. 최근 한국어를 포함한 외국어 인식과 번역기능을 이용한 다양한 스마트폰 앱이 개발되어 여행에 필수품으로 자리잡고 있다. 스마트폰의 카메라기능을 이용하여 촬영한 영상을 인식률을 높이도록 처리하고, Crop기능을 넣어 부분 인식기능을 지원하며, Tesseract-OCR의 train data를 보완하여 인식률을 높이고, Google 음성인식 API를 이용한 음성인식 기능을 통해 인식된 유사한 문장들을 선택하도록 하고, 이를 번역하고 보여주도록 개발하였다. 번역 기능은 번역대상 언어와 번역할 언어를 선택할 수 있고 기본적으로 영어, 한국어, 일본어, 중국어로 번역이 가능하다. 이 기능을 이용하여 차량번호 인식, 사진에 포함된 글자를 통한 검색 등 다양한 응용분야에 맞게 앱을 개발할 수 있다.

In computer science, an encoding is a standardization of converting information to one format for audio, video or text. Therefore, the encoding information of the data should be known to open and read it and there are algorithms detecting encoder of the data. However, some informations of data could be disappeared by packet loss when transmitted on network, especially, if the data is snatched by packet sniffing or eavesdropping from wireless communications. In this paper, we improve the performance of encoding detection algorithm of 'uchardet' program for multi-byte encoded data with errors based on bit-shift algorithm. To simulate the performance, we generated Korean and Japanese text data with errors that is removed some random bits at random positions. Then the detection algorithm are tested using the data and 'uchardet-bitshift' showed better performance than 'uchardet'. When Korean texts are used, 'uchardet' could detect perfectly with ≤0.005% errors but it showed 0% detection rate with ≥1% errors while 'uchardet-bitshift' detected perfectly with ≤0.05% errors and it showed correct detection cases with ≥1% errors. Japanese texts with errors tend to report falsely as Chinese encoding because Japanese texts include lots of Chinese characters. As a results, we improved encoding detection algorithms by applying bit shift operation.
