Binaural hearing aids with a voice transmitter have been widely used to enhance sound quality in noisy environment. However, this system has a limitation on sound-source localization. In this study, we investigated automatic directional-gain control method using geomagnetic sensors to provide directional information to binaural hearing aid user. The loudness gains of two hearing aids were differently controlled based on the directional information between a speaker position and a viewing direction of hearing aids user. This relative directional information was measured by two geomagnetic sensors on hearing aids user and a speaker. The results showed that the loudness gains were accurately controlled and could provide directional information based on the cue of interaural level differences.

In this paper, we propose the Micturition training and Automatic feeding system to enable busy modern people can grow pets more efficiently. This system will be able to operate a smart phone application with a Bluetooth, furthermore, by using the Wifi access the Internet from anywhere and to operate remotely. This system is divided micturition board feeding unit. micturition board consists of a water pressure sensor for detecting micturition and recorder module, speaker for voice output, feeding unit consists of two servo motor for auto feeding and Bluetooth sensor for remote control. Both micturition board and feeding unit produced Arduino board and C language-based Arduino sketch program, feeding unit was able to communicate with the library to support Bluetooth communication.

장애인도 비장애인과 정보접근 기회를 동일하게 가질 권리가 있다. 하지만 청각장애인은 의사소통 수단이나 정보획득의 수단으로부터 소외됨으로써 다양한 사회적 참여에서 배제되기 일쑤였다. 따라서 이 논문에서는 청각장애인을 위한 음성인식을 이용한 자동 자막 시스템을 제안한다. 이 논문에서 제안하는 시스템은 음성 특징 파라미터 추출과 DTW에 의한 음성인식을 통해 음성을 추출하여 화면에 자막으로 나타나게 하는 시스템이다.

A data communication should be carried out by a SSB(Single Side Band) to collect real time position data of fishery ship automatically, and a study on the protocol for exchanging the information with GPS should be made. A research about regional and concentrated maritime information should be first made to obtain ship's voyage data and also, research of the Modem and transmitter-receiver controller for sending voice and data simultaneously through a SSB and of the acquisition of data through a GPS also should be carried out.

Currently, the domestic early warning system is issued differently for each disaster, and is operated independently by relevant organizations from central government to local governments. Representative domestic disaster warning systems include disaster broadcasting using CBS(Cell Broadcasting Service) and DMB(Digital Multimedia Broadcasting) Automatic Emergency Alert Service, DITS(Disaster Information Transform System) transmitted and displayed on TV screens, automatic response system, automated rainfall warning system, and disaster message board. However, due to the difference in the method of issuing each emergency alert at the site of an emergency disaster, the alerts are issued at different times for each media, and the delivered content is also not integrated. If these systems are integrated, it is expected that damage to people's property and lives will be minimized by sharing and integrated management of disaster information such as voice, video, and data to comprehensively judge and make decisions about disaster situations. Therefore, in this study, we present a plan for the integration of the disaster warning system along with the analysis of the operation status of the domestic early warning system.

For the structure of AVLS is required to the GPS-MDT for realtime acquisition the position reporting of vehicle and traffic management S/W. It is necessary that the MODEM using VHF transceiver base on GPS and monitoring program for display base on GIS the traffic status by vehicles position report in management system. The other wise, vehicles among management system that is required the automatic communications protocol for GPS information and mobile's ID. In his paper have studied the VHF modem for transmission the voice and data at same time and S/W for management system using GIS-tool.

This study is intended to suggest ways to improve the quality of the service of subtitles provided for the convenience of viewing for deaf people on e-sports broadcast content and game streamer content. Generally, subtitling files of broadcast content are manually written on air by stenographers, so a delay of 3 to 5 seconds is inevitable compared to the original content. Therefore, the present study proposed the formation of an automatic synchronization calibration system using speech recognition technology. In addition, a content application experiment using this system was conducted, and the final result confirmed that the time of synchronization error of subtitling data could be reduced to less than 1 second.

To help emergency medical dispatchers receive rapid and accurate identification and corrective action status determination of an emergency call, and to support the automatic processing of a voice recognition system to the Korean emergency medical dispatch system, emergency call records were analyzed. Furthermore, a list of Korean symptoms expression were produced and the characteristics of the symptoms that appear on the actual wording of the telephone records were identified. This language list and its characteristics will be useful for training emergency medical dispatchers.

In this research, we developed an practical service module as a application which operating on the smart phones based on the Android operating system. The service module supports on the voice processing function and inquiry windows also. After some documents and screens related on system analysis, service module are designed and implemented. The details about these modules are explained. We can expect to enhance the learning effects of english words memorizing competence for smart-phone users.
