There is a problem that some spoken words are not consistent with the written words when Arabic numerals in Korean language are read. Since some rules for reading the Arabic numerals are not clear, the numerals should be read carefully by recognizing the position of the numbers in sentence, the relationship of the numerals with measurement nouns and other writing elements, and context. In view of technical writing, this work is to appreciate some rules for writing Korean numerals in place of Arabic numerals by studying the works regarding numerals, classifiers and measurement nouns.

This paper describes which UPAN System Implementation using an NAN System as Ubiquitous Numbering and Address System. IT is based to UPTN and eNUM and also scribed by NAN of the ortho phonic korean alphabet. other case, in English. the UPAN system is integrated by two kind of numbering system, one is PSTN, another is domain name and address based IP. By this result we contributed personal ID and many kind of numbering of telecommunications services and all kind of personal ID and numbering system by the proper auto-raising registration. Now, we are confirmed this is key solution of ubiquitous networking and defined supra service structures.

Natural language processing is necessary in order to efficiently perform filtering tremendous information produced in information retrieval of world wide web. This paper suggested an algorithm for meaning of numerals in the text. The algorithm for meaning of numerals utilized context-free grammars with the chart parsing technique, interpreted affixes connected with the numerals and was designed to disambiguate their meanings systematically supported by the n-gram based words. And the algorithm was designed to use POS (part-of-speech) taggers, to automatically recognize restriction conditions of trigram words, and to gradually disambiguate the meaning of the numerals. This research performed experiment for the suggested system of the numeral interpretation. The result showed that the frequency-proportional method recognized the numerals with 86.3% accuracy and the condition-proportional method with 82.8% accuracy.

In this paper, we propose an efficient on-line handwritten digit recognition base on Convex-Concave curves feature which is extracted by a chain code sequence using Smith-Waterman alignment algorithm. The time sequential signal from mouse movement on the writing pad is described as a sequence of consecutive points on the x-y plane. So, we can create data-set which are successive and time-sequential pixel position data by preprocessing. Data preprocessed is used for Convex-Concave curves feature extraction. This feature is scale-, translation-, and rotation-invariant. The extracted specific feature is fed to a Smith-Waterman alignment algorithm, which in turn classifies it as one of the nine digits. In comparison with backpropagation neural network, Smith-Waterman alignment has the more outstanding performance.

We introduce a novel feature extraction scheme for online handwritten digit based on utilizing Zernike moment and angulation feature. The time sequential signal from mouse movement on the writing pad is described as a sequence of consecutive points on the x-y plane. So, we can create data-set which are successive and time-sequential pixel position data by preprocessing. Data preprocessed is used for Zernike moment and angulation feature extraction. this feature is scale-, translation-, and rotation-invariant. The extracted specific feature is fed to a BP(backpropagation) neural network, which in turn classifies it as one of the nine digits. In this paper, proposed method not noly show high recognition rate but also need less learning data for 200 handwritten digit data.

본 논문에서는 변형된 wavelet 변환을 통해 추출한 특징벡터를 이용하여 한국어 숫자음을 대상으로 한 음성인식기를 구현하였다. wavelet 변환은 시간 및 주파수 영역에 대해 다중해상도(multiresolution)를 가지는 신호분석법이다. 본 연구에서는 계산량의 감소와 넓은 주파수 대역을 분석하기 위해, mother wavelet의 형태를 분석 주파수 대역에 따라 변화시키는 방법을 제안하였다. 기존의 wavelet 변환으로 실험한 결과 86.5%의 인식율을 얻었고, 변형된 wavelet 변환의 경우 96%의 인식율을 얻었으며 계산량이 감소하였다. 이와 함께 음성인식에서 널리 사용되는 특징 파라미터인 멜켑스트럼과 FFT 멜스케일 필터 대역(mel scale filter bank)과 비교 실험한 결과 인식율의 향상을 보였다. 이는 제안한 방법이 고주파 대역의 세밀한 시간 해상도와 저주파 대역의 세밀한 주파수 해상도를 지니는데 기인하는 것으로 판단된다.

세계 에이즈의 날을 즈음하여 세계보건기구는 올해의 에이즈 관련 발표를 하였다. 그에 따르면, 아프리카 8개국에서 젊은이의 HIV 감염률이 저하되었다는 소식도 있지만, 생존 감염인의 숫자가 전 세계적으로 3천 9백 5십만 명으로 늘어났고, 2006년도에만 약 430만 명이 새로이 감염되었다고 하였다. 이제껏 에이즈 예방에 성공적인 나라로 여겨왔던 우간다와 태국에서 신규 감염률이 증가했다는 안타까운 소식도 전해지고 있다. 그 무엇보다도 문제점으로 지적된 것은 대부분의 정부가 에이즈에 대해 안이한 생각을 가지고 있으며 적극적인 예방활동에 대한 의지도 부족하다는 것이다. 올해의 에이즈의 날 슬로건은 작년과 같은 "STOP AIDS, Keep the promise"이다. 전 세계적으로 에이즈 행사가 열렸고 아프리카, 미국, 영국 수상 등이 연설문을 발표하였는데, 이를 인터넷 자료를 중심으로 요약하였다.

본 연구는 휴대전화기의 문자메시지 전송UI가 사용자 만족도에 미치는 영향에 관한 것이다. 휴대전화기의 문자메시지 전송UI은 한글, 영문, 숫자, 특수문자, 기능키의 조합으로 이루어지고, 연구결과 사용자 만족도에 가장 많은 영향을 미치는 것은 한글 모음 입력임이 입증되었다. 가장 만족도가 높은 모음 입력방식은 점과 선을 이용하여 모음을 조합하는 방식이며, 짧은 동선과 그로 인한 입력시간 단축이 주요인이었다. 조사방법은 사용자 대상 설문조사를 사용하였고, 연구 방식은 문장을 입력할 때의 각 휴대전화 문자입력 UI의 동선과 버튼을 누르는 횟수를 비교 분석하여 결과를 도출하였다.

In this paper, the development of an editing system for Hanguel sentences is described. Each Hanguel character is composed of 24basic phonemes and 1 dummy code with satisfactorily good quality, and an editing Is simply performed by using Hanguel and alphanumeric characters. The experiments demonstrate th e possibility of developing an intelligent terminal for Hanguel characters. This experimental system is implemented on the minicomputer NOVA 1200. Furthermore HIT (Hanguel -Inteuigent -Terminal) which is low cost but shows high level functions by the incorporation of a microprocessor and a CRT-display is given.

In this paper, we propose speech control system for a various control device in the car with real time control speech. A real time speech control system is detected start-end points from speech data processing by A/D conversion, and recognize by one pass dynamic programming method. The results displays a monitor, and transports control data to control interfaces. The HMM model is modeled by a continuous control speech consists of control speech and digit speech for controlling of a various control device in the car The recognition rates is an average 97.3% in case of word & control speech, and is an average 96.3% in case of digit speech.
