Speech recognition is now one of the most widely used technologies in HCI. Many applications where speech recognition may be used (such as home automation, automatic speech translation, and car navigation) are now under active development. In addition, the demand for speech recognition systems in mobile environments is rapidly increasing. This paper is intended to present a method for instant recognition of the Korean vowel 'ㅡ', as a part of a Korean speech recognition system. The proposed method uses bulk indicators (which are calculated in the time domain) instead of the frequency domain and consequently, the computational cost for the recognition can be reduced. The bulk indicators representing predominant sequence patterns of the vowel 'ㅡ' are learned by neural networks and final recognition decisions are made by those trained neural networks. The results of the experiment show that the proposed method can achieve 88.7% recognition accuracy, and recognition speed of 0.74 msec per syllable.

[ $\sqcap$ ]' shape of Jeonnam Area has not been well-known so far. This study is about when, how and on what type the '$\sqcap$' shape had settled among many 'ㅡ' shape houses. The Anchae of Jeonnam Area which appeared 17C. contrasts with 'ㅡ' shape. Especially, the head family's house might have been expected to develop with special difference. 'ㅡ' shape had been built much more than the '$\sqcap$' shape around 20C when modernization had been ripen. It was big event that '$\sqcap$' shape, the head family's house, had been pulled down and then 'ㅡ' shape had been newly built. (Ui Seong-ryeol house) The reason why 'ㅡ' shape had been built instead of '$\sqcap$' shape might be that people accepted the change of 'modernization', that is to say, people accepted convenience and opening. The plan of '$\sqcap$' shape consists of Daecheong and Anbang at the center of Momche, and Jageunbang and Jangji at both sides. In the '$\sqcap$' shape, the center of Momche is wide dand light unlike 'ㅡ' shape. Unjoru, Nogudang, Yundoseo house have long wing and have more encircling Anmadang than other houses, which are well known for a house for a man of noble birth.

Houses in Jeju city are divided into separated types and combination types of household affairs space. Other special types are separated-kitchen type. Separated household affairs space type is mostly built. Separated household affairs space type were sitting room + Gopang separate type and separate sitting room type. Combination household affairs space type made from sitting room, kitchen, Gopang and Chabang(Dinning room) put together as space differentiation, also into classes sitting room + kitchen + Gopang + Chabang type, sitting room + kitchen + Chabang type, sitting room + kitchen + Gopang, sitting room + kitchen type by combination household cares space type. Separated-kitchen type was one of the special type from separated-kitchen type of traditional housing, and type with continuous. Houses in Jeju city were 3 kan type and 4 kan type. 4kan type was mostly built. ㅡ shape is kept as plan shaped of straight shape, and roof shape is showed as ㅡ shape gathering roof. ㅡ shape + part projection type talls part projecting type as happened in Gopang, and Chabang. Roof is gathering roof, and when it is showed ㄱ shape by Gopang, Chabang, and kitchen are projected. ㅡ shape + total projection shape is one of the room become totally projected by Gopang and Chabang, can be happen with small room or kitchen, and roof as gathering roof shaped with ㅡ shape, ㄱ shape, ㄷ shape, unsystematic ㄹ shape, and various shapes.

In order to examine the legibility of the Hangul letters which is a syllabic, the three kind of visual charts were made of the ninety eight($14{\times}7$) Hangul Gothic type letters by the laser printer. These Hangul letters were constructed with the 13 consonant letters which are 'ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅌ, ㅍ, ㅎ', and the 6 vowel letters which are 'ㅏ, ㅓ, ㅗ, ㅜ, ㅡ, ㅣ'. The two examination methods were used, One is the discriminating the letters on the visual chart by men having 1.5 visual acuity. The other is the using the laser printer's resolution. Obtained data by these examination methods are the minimum readable size values of the letters and the maximum readable distance values from the reader to the objects. From these data the relative legibility of the Hangul letters were calculated, where the letter ㄱ was chosen for the standard. This resultant data were analyzed. In this result, the mean legibility of these Hangul letters descended in the order of 'ㄱ, ㄴ, ㅅ, ㄷ, ㅈ, ㅇ, ㅁ, ㅋ, ㅌ, ㅍ, ㅎ' Which are the consonant letters being in these letters. And the mean legibility descended in 'ㅣ, ㅡ, ㅏ, ㅗ, ㅓ, ㅜ' order. The mean legibility is dependent on used consonant letter more then on used vowel.

This study investigated the characteristics of architectural planning in the youth training centers, which were introduced to the magazines from 2000 to 2010. The result are as followings. Firstly, the youth training centers were located mainly in general residential area, that the youth could be easily accessible. And, it were located mainly in green natural area, which is adjacent to the mountain or park. The site area of the youth training center was analyzed to approximately $10,000m^2$ below. Secondly, the placement and the form of the youth training center is divided two types, which are a single and two buildings type. A single building case is found the type of 'ㄴ' and 'ㄷ' shape, and two buildings case is found the type of 'ㄴ + ㅡ', 'opened ㅁ', 'ㅡ + ㅡ' shape. It is found mostly the type of 'ㄷ' shape. Thirdly, the youth training center is planned mostly with fifth stories above ground and three underground levels. And, sometimes it is planned a mixed-use buildings with a sports center, community center and senior welfare center. Lastly, the space of youth training center is zoned horizontally for each mass of building, which is planned the educational, cultural and sports facilities. And, it is zoned vertically some of the sports facilities and administrative support facilities in the underground, and a educational and cultural facilities on the ground.

The paper studies on the site and space composition of Lee Ha-Bock's traditional thatched roof house. The house is located at a site with back to the mountain and facing the water and the rear and front mountains formulate a shape of Myungeonhyung(a sleeping dog figure) with HyungGug theory of Pungsu. The house has ㄱ shaped Anchae, ㅡ shaped Sarangchae and Gwangchae. Those are formulate ㅁ lay out followed the land form. Through the research I found the house shows a typical traditional farmhouse in the middle of Korea of Josen period. Nowadays there are many large Giwajip(tile roofed house) of Josen period is remained but only a few thatched-roof house is lived. In this situation, the house has considerable architectural values as a traditional thatched roof house.

ERP의 일종인 MMN(Mismatch Negativity)은 언어의 청각 인지정보 처리과정(central auditory processing)을 규명하는 데 유용한 수단으로 이용되어 왔다. 그런데, 최근의 연구들은 이러한 MMN이 청각 자극뿐만 아니라 시각 자극에 의해서도 검출될 수 있음을 밝혀냈다. 본 연구는 이러한 시각적 MMN을 이용하여 뇌에서 이루어지는 한국어 화자의 무의식적인 한국어 문자 정보처리과정을 규명하려고 시도하였다. 본 연구에서는 한국어의 글말 최소쌍 '므'/'모'와 '므'/'무', 이에 대응되는 비언어자극 '+ㅡ'/'+ㅗ'와 '+ㅡ'/'+ㅜ'(+표시의 아래에 모음을 붙여서 만든 인공문자, 그림1 참고)를 수동적(passive) Oddball paradigm으로 제시하고 언어 자극에 대한 EEG를 비언어자극과 비교 하에 측정, 분석하였다. 본 연구의 결과, 언어자극과 비언어자극 모두에서 시각적 MMN이 검출되었다. 하지만, 언어자극의 시각적 MMN이 비언어자극의 시각적 MMN보다 높게 나타남을 확인하였다. 이는 한국어 모국어화자들이 무의식적인 인지과정에서 언어자극이 갖는 물리적인 시각 정보뿐만 아니라 한국어 문자의 언어적 정보도 함께 처리하고 있음을 보여주는 것이다. 본 연구의 결과들은 한국어 글말의 무의식적인 인지처리과정을 밝혀주는 한편, 한국어 문자가 인지과학에서 갖는 중요한 지위를 보여줄 수 있을 것으로 기대된다.

Hunminjeongeum was made by the Great King Sejong, and composed of 17 consonant and 11 vowel letters. All the 28 letters were made according to the shape of vocal organ or space at the point of articulation for each letters. This review article focused on phonetic and phoniatric consideration for explanation of the designs of the middle vowel letters, especially three main vowel letters [ • (天, heaven), ㅡ (地, earth), ㅣ (人, human)] using video-fluoroscopic evaluation as well as computed tomography scanning, etc. During articulating / • / sound, a ball-like space at frontal portion of the oral cavity was found, tongue was contracted, and sound was deep (舌縮而聲深). During /ㅡ/ sound, a flat air space between oral tongue and hard palate was created. Tongue was slightly contacted neither deep nor shallow (舌小縮而聲不深不淺). During /ㅣ/ sound, tongue was not contacted and Sound is light (舌不縮而聲淺). Tongue was moved forward making longitudinal oro-pharyngeal air space. So, I'd like to suggest that we had better change the explanation drawing from a philosophical modeling to a more scientific modeling from real vocal tract space modeling during articulating middle vowels of Hunminjeongeum.
