The previous research has been mainly focused on individual technology of voice recognition, voice synthesis, translation, and bone transmission technical. Recently, commercial models have been produced using aforementioned technologies. In this research, a new automated translation support system concept has been proposed by combining established technology of bone transmission and wireless system. The proposed system has following three major components. First, the hybrid system consist of headset, bone transmission and other technologies will recognize user's voice. Second, computer recognized voice (using small server attached to the user) of the user will be converted into digital signal. Then it will be translated into other user's language by translation algorithm. Third, the translated language will be wirelessly transmitted to the other party. The transmitted signal will be converted into voice in the other party's computer using the hybrid system. This hybrid system will transmit the clear message regardless of the noise level in the environment or user's hearing ability. By using the network technology, communication between users can also be clearly transmitted despite the distance.

인체의 모양으로 체격을 외견상의 특징에 의하여 분류한 유형을 체형이라 한다. 이러한 체형을 흉위로 나타낼수 있으며 통계적으로 기질, 성격 등과 밀접한 상관관계가 있는 것으로 조사되고 있다. 따라서 본 논문에서는 기질, 성격 등 개인적인 특징이 내포되어 있는 목소리를 분석하여 흉위와의 상관성을 도출함으로써 음성 분석을 통한 흉위 예측에 관한 연구를 수행하고자 한다. 이를 위해 흉위에 따라 피실험자 집단을 분류, 구성하고 웃음소리에 대한 음성 에너지 크기 및 스펙트럼을 측정하여 상호간의 비교, 분석을 통해 흉위를 예측할 수 있는 실험 결과를 도출하고자 한다.

In this paper, a MSS-NOVO method that combines the HMM composition method with a noise reduction method is proposed for speech recognition in noisy environments. This combined method starts with noise reduction with modified spectral subtraction (MSS) to enhance the input noisy speech, then the noise and voice composition (NOVO) method is applied for making noise adapted models by using the noise in the non-utterance regions of the enhanced noisy speech. In order to evaluate the effectiveness of our proposed method, we compare MSS-NOVO method with other methods, i.e., SS-NOVO, MWF-NOVO. To set up the noisy speech for test, we add White noise to KLE 452 database with different SNRs range from 0dB to 15dB, at 5dB intervals. From the tests, MSS-NOVO method shows average improvement of 66.5% and 13.6% compared with the existing SS-NOVO method and MWF-NOVO method, respectively. Especially our proposed MSS-NOVO method shows a big improvement at low SNRs.

Today's universities have a keen interest in educational reform. The issue of population decline in college-age due to population decline is not new. Universities have been developing quantitatively for a long time and are now considering ways to survive rather than qualitative growth. Since the sharp decline in the school-age population due to the population decline has no clear solution immediately, universities are overcoming this crisis by creating many alternatives. Attracting international students is one of them. In this study, the effectiveness of photovoice was examined through the analysis of the case of the Korean-Japanese convergence cartoon class. The photo-voice method has sufficient potential as a teaching method for foreign convergence classes and can be expected to play a role as a teaching method suitable for students participating in convergence classes with different social, cultural, and linguistic backgrounds. In particular, in the convergence class, since participating students generate research materials through photo production, it can be a tool for inner exploration necessary for webtoon production and a tool for narrative inquiry for storytelling. It is expected that expanding the understanding and use of photo voice will have the methodological value of convergence classes. In addition, the teaching method using photo voice produced in the composition of photos and stories is likely to be used as an appropriate tool for convergence classes for students with different social, cultural, and linguistic backgrounds.

It is necessary to have enough transmission capacity for advanced internet techniques and various digital home appliances networking. Home appliances interface IEEE1394 technique has much wealthy transmission skill. IEEE1394 is using home appliances through various information form image and voice change data real time print out. In this paper, AVC CTS technology and IEEE1394 technology are introduced. Digital Video Camera includes compression format using DV. System composition control is consisted of protocols like IEC-61883 and AV/C command set standard.

An important modelling requirement for multimedia systems is the representation of temporal constraints among several different media that ordinarily arise in multimedia application. The multimedia system which integrates various types of data is required to express voice, image, text and graphic data with simultaneousness or an arbitrary time intervals. The purpose of this study is to analyze the temporal reationships and synchronization among several different kinds of medium. Moreover, it proposes a Multimedia Display-Time Composition Model (MDTC Model) which guarantees a representation of any kind of temporal synchronization among more than two kinds of medium. The proposed model is applied to a company advertizing system. Finally, a multimedia authoring tool based on the MDTC Model is implemented.

인터넷을 이용한 여러 응용 서비스들 중에서 저렴한 비용으로 음성을 전송할 수 있는 VoIP 서비스의 발전으로 사용자의 급격한 증가가 예상된다. VoIP에 mobility, universal number, multiparty conference, voice mail, automatic call distribution과 같은 고품질의 서비스를 제공하기 위해서는 시그널링이 가능한 표준화된 프로토콜이 필요하다. 현재 IETF의 SIP(Session Initiation Protocol)가 빠른 호 설정과 parsing 및 compile이 쉬운 장점으로 인해 SIP를 기반으로 한 VoIP 서비스를 제공하기 위해 국내외적으로 SIP 기반 구성요소에 대한 개발이 진행 중이다. 본 논문에서는 사용자가 보내는 Request(INVITE) 메소(method)를 처리해주는 SIP 서버의 부하 경감, 망 운용의 효율성, 많은 사용자에 대한 서비스를 제공하기 위해 새로운 서버 유형인 Hybrid형 SIP 서버를 제안하고, 이를 이용하여 새로운 방식의 인터넷폰을 설계 하였다.

이 연구는 한국 전통음악 녹음자료의 통일표제 기술원칙에 관한 모형안을 제시한 것이다. 주요부분을 중심으로 그 결과를 요약하여 보면 다음과 같다. 비악곡형식의 경우에는 구국악의 아악은 속명을, 민속악은 일반화된 표제를, 신국악은 작곡자가 최초로 표현한 원표제를 통일표제로 하여 각 괄호 속에 기입하되 식별적 요소를 제외하고는 연주수단 등을 생략한다. 그러나 기악곡의 악곡형식의 경우에는 악곡형식, 연주수단 축차번호, 작품번호, 조, 기타 한정어구나 설명구의 순으로 통일표제를 구성하여 각 괄호 속에 기술한다. 그리고 구국악의 성악곡 중 합창곡의 연주수단은 남성, 여성, 혼성합창으로만, 독창곡은 남성, 여성독창으로만 기술하고, 신국악은 양악의 형식을 따른다. 이 밖에 상이한 작품이 동일한 통일표 제를 가질 경우는 연주수단, 축차번호 조 한정어구나 설명구, 발행사명, 발행년 등을 부가하여 구별하도록 한다.

The aim of this study is to examine children's desires in a toy library and what they want to do there in order to reflect their opinions on constructing a toy library in a child care center. The study has been conducted by participatory observation on a 'toy library' project consisting of 20 five-year-olds attending B public child care center in Seoul. Observational notes were taken with voice and video recordings. The results of analysis on collected data are as follows. First, the children wanted to call the toy library a toy playground because a toy library is not for study but for play and they wanted space for rest and display with no surveillance camera. Second, they wanted to play freely without any interruption, even leaving things scattered and also wanted to play with parents and friends. Discussion followed in the view of children's right to play and to express their opinions.
