This paper introduces a Web site login system that uses user's native voice to improve the bother of remembering the ID and password in order to login the Web site. The DTW method that applies fuzzy inference is used as the speaker recognition algorithm. We get the ACC(Average Cepstrum Coefficient) membership function by each degree, by using the LPC that models the vocal chords, to block the recorded voice that is problem for the speaker recognition. We infer the existence of the recorded voice by setting on the basis of the number of zeros that is the value of the ACC membership function, and on the basis of the average value of the ACC membership function. We experiment the six Web sites for the six subjects and get the result that protects the recorded voice about 98% that is recorded by the digital recorder.

In this study, through the accumulated technologies such as real-time monitoring of power consumption using power line communication (PLC) method, power control, and automatic blocking of standby power, to commercialize them, we developed the hardware design, algorithm, protocol and module along with data transmission using PLC. We conducted the study to develop advanced products. We also proposed cloud-based smart outlet products with a novel type of outlet. These products can measure the internal power consumption through the H/W modules and the modules that control the power of household appliances connected to the smart outlets and smart plugs. Subsequently, they transmit the measurements to the energy saving system server via a communication module. This system can control the terminal device connected to the Gateway (G/W) server through a mobile phone. This will allow the customer to check the power consumption of the building at any given time, to turn the terminal on/off, and to maximize the energy efficiency during the construction of new apartments or multi-family housing in an area.

본 논문에서는 안드로이드 플랫폼 기반의 국내 여행지 및 지역 축제 정보를 제공하는 Walking Life Festival 애플리케이션을 설계하고 구현한다. 이 애플리케이션은 스마트폰 내장 센서 중 걸음 횟수 센서(Step Counter Sensor)와 걸음 감지 센서(Step Detector Sensor), 가속도 센서(Acceleration Sensor), GPS 센서 등을 활용한다. 그리고 Google Map API와 Public Open API를 활용하여 국내 여행지 및 지역 축제정보를 제공한다. 이 애플리케이션은 Shared preference API를 사용하여 자동 로그인 기능을 구현한다. 그리고 로그인 정보를 데이터베이스에 저장할 때는 해시 알고리즘을 통해 입력된 평문 데이터를 받아서 암호화하여 저장한다. Google Map은 Google.maps.LatLngBounds() 메서드를 활용해서 객체를 생성한 후 extends 메서드를 통해 위치정보를 전송하도록 구현한다. 또한, 이 애플리케이션은 국내 여행지와 관련된 지역 축제 개최 시기를 알림으로써 축제 참여 기회를 높임으로써 국내 관광 산업 활성화에 기여한다.

In future, hospitals are expected to automatically issue remote transcriptions. Many general hospitals are planning to encrypt their medical database to secure personal information as mandated by law. The electronic medical record system, picture archiving communication system, and the clinical data warehouse, amongst others, are the preferred targets for which stronger security is planned. In the near future, medical systems can be assumed to be automated and connected to remote locations, such as rural areas, and islands. Connecting patients who are in remote locations to medical complexes that are usually based in larger cities requires not only automatic processing, but also a certain amount of security in terms of medical data that is of a sensitive and critical nature. Unauthorized access to patients' transcription data could result in the data being modified, with possible lethal results. Hence, personal and sensitive data on telemedicine and medical information systems should be encrypted to protect patients from these risks. Login passwords, personal identification information, and biological information should similarly be protected in a systematic way. This paper proposes the use of electronic acupuncture with a built-in multi-pad, which has the advantage of being able to establish a patient's physical condition, while simultaneously treating the patient with acupuncture. This system implements a sensing pad, amplifier, a small signal drive circuit, and a digital signal processing system, while the use of a built-in fuzzy technique and a control algorithm have been proposed for performing analyses.
