The study on speech recognition and understanding has been done for many years. In this paper, we propose a new type of recurrent neural network architecture for speech recognition, in which each output unit is connected to itself and is also fully connected to other output units and all hidden units [1]. Besides that, we also proposed the new architecture and the learning algorithm of recurrent neural network such as Backpropagation Through Time (BPTT, which well-suited. The aim of the study was to observe the difference of Arabic's alphabet like "alif" until "ya". The purpose of this research is to upgrade the people's knowledge and understanding on Arabic's alphabet or word by using Recurrent Neural Network (RNN) and Backpropagation Through Time (BPTT) learning algorithm. 4 speakers (a mixture of male and female) are trained in quiet environment. Neural network is well-known as a technique that has the ability to classified nonlinear problem. Today, lots of researches have been done in applying Neural Network towards the solution of speech recognition [2] such as Arabic. The Arabic language offers a number of challenges for speech recognition [3]. Even through positive results have been obtained from the continuous study, research on minimizing the error rate is still gaining lots attention. This research utilizes Recurrent Neural Network, one of Neural Network technique to observe the difference of alphabet "alif" until "ya".

The multiple acupuncture techniques have been used to relieve the pain of lateral ankle sprain. Recently, early functional rehabilitation is emphasized in rehabilitative concepts using active ROM, facilitated proprioception, alphabet exercise and so forth. Similarly, in oriental rehabilition medicine, traditional movement technique called "Dong-Ki" has been used to relieve pain of ankle sprain. So we used "Dong-Ki" technique with SSP(silver spike point) electrotherapy transformed from alphabet exercise and evaluated the effects in method of randomized controlled trials. Methods : 27 outpatients with lateral ankle sprains were randomized into two groups : 15 samples and 12 controls. Sample group was treated with "Dong-Ki" technique(writing his name with foot) with SSP electrotherapy to relieve pain during additionally. "Dong-KI". Outcomes were measured by 10cm VAS and ankle circumference(cm). Results : In terms of VAS, Sample group had inclination of pain relieving but not significantly meaningful. In terms of ankle circumference measurement, Sample group showed significantly improved.

This article aims to discuss the transition of the Kazakh writing system from Cyrillic to Latin. First, the study investigates the relationship between the Kazakh Cyrillic alphabet and phonology, in order to linguistically evaluate the efficiency of the writing system. Second, the process of determining the Kazakh Latin alphabet is discussed in terms of the Kazakh phonological system. Third, the factors that determined the Latin alphabet of Kazakh language are analyzed. In Kazakh, the phonemic system is subject to controversy among linguists, but it can be said that the phonological system basically follows the one-to-one correspondence to the Russian and Kazakh phonemes. As for the depth of orthographies, Kazakh Cyrillic writing system is not based on the shallow orthographies, so it incorporates morphophonemic information to make skilled readers understand easier. The political and social aspects are considered as a cause of the alphabet change. Although there are studies suggesting the conversion of the writing system is caused by the extrinsic factors rather than the intrinsic factors, the five criteria of Smalley (1964), which compromise the intrinsic and extrinsic factors, are also persuasive. The five factors are 1) Maximum motivation for the learner, 2) Maximum representation of speech, 3) Maximum ease of learning, 4) Maximum transfer, 5) Maximum ease of reproduction.

In this paper, we described the development of a Korean Manual Alphabet (KMA) learning game with avatar. KMA letters correspond to the vocabulary of Korean Sign Language (KSL) when spelling a word. Each KMA letter corresponds to a letter of the Korean Alphabet (KA) and KA is represented as hand shapes by sign language user. We developed a KMA learning game for a beginner to learn KMA letters from sign language avatar and practice KMA presentation easily. The system composed of sign language teacher avatar GUI popup window based on OpenGL, KMA letter recognition module, KA letter raining game module and USB camera. A user learns a KMA letter with expressing KA syllabic from avatar and inputs a KMA letter to the system using USB camera. We evaluated the efficiency of the developed system through the verification of users.

The mobile user interface becomes important to access information fast and conveniently, especially in the ubiquitous computing environment. Among many new services in the mobile computing environment, ubiquitous information networking service was studied using korean alphabet (consonant or vowel) domain-names including Korean single-character domain-names. Instead of handling long English/Korean URL-strings, as convenient user interface for information access, the Korean single-character/alphabet domain names are more convenient than long URL strings to retrieve information and to send information in the wired Internet as well as in the mobile Internet. We studied the convenience of Korean alphabet domain names with PCs as well as with mobile phones. We introduce the Implementation and the application of ubiquitous information portal, which has the functionality of Text to Speech (TTS) and is accessible with Korean single - character/alphabet domain - names.

Given an n-length text T over a $\sigma$-size alphabet, we present a compressed representation of T which supports retrieving queries of rank/select/access and updating queries of insert/delete. For a measure of compression, we use the empirical entropy H(T), which defines a lower bound nH(T) bits for any algorithm to compress T of n log $\sigma$ bits. Our representation takes this entropy bound of T, i.e., nH(T) $\leq$ n log $\sigma$ bits, and an additional bits less than the text size, i.e., o(n log $\sigma$) + O(n) bits. In compressed space of nH(T) + o(n log $\sigma$) + O(n) bits, our representation supports O(log n) time queries for a log n-size alphabet and its extension provides O(($1+\frac{{\log}\;{\sigma}}{{\log}\;{\log}\;n}$) log n) time queries for a $\sigma$-size alphabet.

In many practical problems in signal processing and control, the signal values are often restricted to belong to a finite number of levels. These questions are generally referred to as "finite alphabet" problems. There are many applications of this class of problems including: on-off control, optimal audio quantization, design of finite impulse response filters having quantized coefficients, equalization of digital communication channels subject to intersymbol interference, and control over networked communication channels. This paper will explain how this diverse class of problems can be formulated as optimization problems having finite alphabet constraints. Methods for solving these problems will be described and it will be shown that a semi-closed form solution exists. Special cases of the result include well known practical algorithms such as optimal noise shaping quantizers in audio signal processing and decision feedback equalizers in digital communication. Associated stability questions will also be addressed and several real world applications will be presented.

The Korean Phonetic Alphabet(KPA) as devised by H. B. Lee on the basis of Han-geul, the Korean Alphabet, was incorporated into the Hangul Word Processor(HWP) 1. $^{*}$ to be used on personal computers. With the upgrading of the HWP software from $1.^{*}$ to more sophisticated versions of $2.^{*}$, $3.^{*}$, etc., it became necessary to convert the HWP $1.^{*}$ KPA into upgraded version. This paper traces the history of the computerized KPA software from the initial version of HWP $1.^{*}$ to the latest one.

Neural oscillator can be applied to oscillatory systems such as analyses of image information, voice recognition and etc. Conventional EBPA (Error back Propagation Algorithm) is not proper for oscillatory systems with the complicate input`s patterns because of its tedious training procedures and sluggish convergence problems. However, these problems can be easily solved by using a synchrony characteristic of neural oscillator with PLL(Phase Locked Loop) function and by using a simple Hebbian learning rule. Therefore, in this paper, a technique for Recognition of the Korean Alphabet using Phase Synchronized Neural Oscillator was introduced.

The purpose of this paper is to suggest that the International Phonetic Alphabet be included in English curriculum and taught in English classroom. Current English curriculum for elementary and middle school students doesn't specify anything for the education of the IPA. The knowledge of IPA is essential for the students to study by themselves how to pronounce English words. The IPA, however, is either too little or too much to be taught at school. It is too little in that it doesn't tell us anything about allophones, the knowledge of which could enable us to get rid of foreign accents as much as possible. It is too much in that it can represent more than one sounds (e.g., /ɔ/ in American and British English). To overcome these drawbacks, it should be introduced gradually with the allophones in the same environments. The correct vowel sounds should be introduced with the aid of pronunciation dictionary so that the students could get their own vowel quality. Moreover, the IPA symbol should be adopted for the English textbooks.
