본 논문에서는 스마트폰 인증기법 중 연산기반 패스워드 기법을 통하여 사용자의 접근을 제어하고 비인가 접근자에 대해 얼굴을 촬영하여 비인가 접근 시도를 소유자가 확인할 수 있도록 한다. 우선적으로 사용자 접근 제어를 위해 연산기반 패스워드 기법을 이용하고, 비인가 접근이 확인되는 경우 잠금 기능과 함께 비인가자의 얼굴을 촬영하여 소유자가 비인가자를 확인할 수 있는 카메라 액션을 추가한다. 스마트폰 소유자는 사용자의 접근을 제어하고 비인가자의 접근에 대한 확인을 할 수 있으므로 안전성에 대한 향상을 기대할 수 있다.

The internet and wireless communication technologies are creating ubiquitous environments in which various services are expected anytime and anywhere. Many hardware facilities have been developed and system structures are suggested for mobile services to realize a ubiquitous computing environment with appropriate quality. But these applications are not designed in the consideration of the general capabilities to perform user's wireless and mobile communication/transaction. Consequently, different needs from users are not sufficiently satisfied yet. In this study, we suggest structure of the emerging network system for mobile commerce that provides users with seamless and ubiquitous environments using location information which exploit context-aware technology.

A face recognition algorithm for the user identification procedure of automatic teller machine(ATM), as an application of the still image processing techniques is proposed in this paper. In the proposed algorithm, face recognition techniques, especially, face region detection, eye and mouth detection schemes, which can distinguish abnormal faces from normal faces, are proposed. We define normal face, which is acceptable, as a face without sunglasses or a mask, and abnormal face, which is non-acceptable, as that wearing both, or either one of them. The proposed face recognition algorithm is composed of three stages: the face region detection stage, the preprocessing stage for facial feature detection and the eye and mouth detection stage. Experimental results show that the proposed algorithm can distinguish abnormal faces from normal faces accurately from restrictive sample images.

It was already proved that ATM stability and flexibility of service application, but because of the various characteristics of traffics and the QoS on user demand caused by them, there are a lot of researches for traffic management method. However, there are a few of researches for ATM routing method acting on traffic management practically. In this paper, we focus on multi-path routing method transporting cells with multiple paths and compare this method with existing single path routing method and analyze multi-path routing method into three elements with simple formula and propose anew methods improving the performance of ATM routing and simulate these methods.

The paper describes the design and implementation of Auto-Presentation Feature, Hanuri/C, as Client/Server tool. Hanuri/C provides editing functions for the sequence, period, type, and repeating number of auto-presentation. With the pre-fixed sequences users can get automated presentations through Hanuri/C. The proposed auto-presentation function provides an ability to automatically present the data in the database system without user intervention.

인터넷과 무선 이동통신 등이 보편화되면서 두 기술을 접목한 WAP(Wireless Application Protocol)[1]이 등장하였으며, 다수의 사용자 요구를 동시에 효율적으로 처리하면서 다양한 문서 단말기로부터 요청을 신속하게 처리할 수 있는 WAP 게이트웨이(gateway)에 대한 연구가 여러 연구 그룹에서 수행되고 있다. WAP 스택은 이러한 연구 중의 가장 기본적인 기술이다. 본 논문에서는 Java의 기본적인 서비스인 멀티쓰레드를 이용하고, 컨테이너 유효 리소스의 효율적 관리를 위해 접속 풀링(connection pooling) 기능을 적용하여 UDP(User Datagram Protocol)[4], WTP(Wireless Transaction Protocol)[2], WSP(Wireless Session Protocol)[3] 계층을 설계한다. 설계 방법론은 UML(Unified Modeling Language)을 사용한다.

For the service and creation of new space, the next generation smart device for interactive space using tailor-made contents process serve as an opportunity for the growth of new special display due to the integration of the latest digital technology. The application of next generation technology is in the field that most people expect. So, this thesis serving as the beginning, it is hoped that the smart mirror and wall industry in Korea will play a practical and academic momentum. An interactive environment which is the smart device can be realized when space displays based on smart device built on the experience of the user can provide various tailor-made processes such as academics, performances, meetings, virtual experience, exhibits and promotion, and through this a strategic direction was suggested for the development of each field.

Recently, a great many people are concerned about promoting their health because medical science and scientific technology has become much larger and more develop. Thus, the person who interested in health wants to confirm his condition whatever he may take a meal or exercise. But it is disappointed of our expectation. By reason that many people doesn't know what changes will occur in their body. In this paper, we are going to introduce our Health Care Managing System which could display a physical variation, in addition, we will also propose how to control serial data from wireless sensors. We implemented this system using ZigbeX and Java application.

An orienteering is a sport that play with a map, a compass and a point map. However, it is difficult to measure the number of steps and the play time accurately. In this paper, we develop the Orienteering application to integrate the essential function for the orienteering sport. since the integrated UI display the map, the compass and the number of step at the same time, it is easy for an user to watch the progress of the orienteering and improve the accuracy by measuring the steps and the play time.

최근 Siri, S Voice 등과 같이 스마트폰에 음성으로 명령을 내리는 기능이 보편화되고 있다. 하지만 기존의 음성명령 시스템은 사전에 정의된 명령어가 아니면 사용이 불가능하며 어떤 명령어들이 사용가능한지 확인하기도 어렵다. 본 논문에서는 사용자에게 좀 더 편리한 인터페이스를 제공하기 위한 목적으로, 사용자가 직접 음성명령을 등록할 수 있는 안드로이드폰용 음성명령 앱을 개발한다. 본 논문에서 개발한 음성명령 앱은 사용자가 등록한 임의의 음성을 인식하여 안드로이드폰에 설치된 애플리케이션을 실행시키거나, 특정 번호로 전화를 걸거나, 특정 번호로 문자메시지를 보낼 수 있다. 본 논문에서 개발한 앱을 통해 사용자는 보다 편리하게 스마트폰에 음성명령을 내릴 수 있다.
