This paper describes the results of 2D mapping, feature detection and matching to create the surrounding environment in the mounted stereo camera on Mobile robot. Extract method of image's feature in real-time processing for quick operation uses the edge detection and Sum of Absolute Difference(SAD), stereo matching technique can be obtained through the correlation coefficient. To estimate the location of a mobile robot using ZigBee beacon and encoders mounted on the robot is estimated by Kalman filter. In addition, the merged gyro scope to measure compass is possible to generate map during mobile robot is moving. The Simultaneous Localization and Mapping (SLAM) of mobile robot technology with an intelligent robot can be applied efficiently in human life would be based.

In China, commercial banks have launched mobile banking one after another, and the homogeneous products make the competition of mobile banking extremely fierce. Mobile banking monthly active users (MAU) is an important indicator to evaluate the operation results of mobile banking. How to improve mobile banking monthly active users is a problem faced by commercial banks. The purpose of this study is to explore strategies to increase monthly active customers of mobile banking with the help of vending machines. This research is carried out through the literature method and case method. The research results show that the use of vending machines can not only effectively increase the monthly active customers of mobile banking, but also realize the differentiation strategy to occupy the mobile banking terminal market. At the same time, this study is helpful and instructive for commercial banks to develop their business.

Mobile SNS like facebook is famous as an app which users cooperate others and share information without regard to time and place. But it is necessary to evaluate the mobile app accessibility in view of the disabled and the aged to check if they get appropriate interface service to use such a popular app. Mobile app accessibility is an indicator of equal opportunity to mobile app for all users regardless of cognitive and physical attribute. Therefore, this paper evaluates accessibility of facebook and kakaotalk mobile SNS, apprehend the status of conform to the manual, and suggest an improving way, based on 'mobile application accessibility guideline' announced by government and 'mobile application (Android) accessibiliy checking manual(v1.0)' by National Information society agency.

Mobile devices have become the most influential media platform. Mobile advertising has thus grown much faster than any other type of advertising. This study is designed to examine antecedents of attitude toward mobile ads, antecedents such as irritation, personalization, and online information privacy concerns. The study also examines consumers' attitudes toward mobile ads as an antecedent of mobile advertising acceptance. Study findings suggest that irritation is not a statistically significant predictor of attitude toward mobile ads. An antecedent found to be positively related to attitude toward mobile ads is personalization and one found to be negatively related is online privacy concerns. Finally, consumers' attitudes toward mobile ads are found to be positively related to a general acceptance of mobile advertising. Practical implications are discussed.

최근 무선통신망의 발전에 따라 무선 인터넷 시장이 빠르게 성장하면서 이동성을 기반으로 하는 서비스에 대한 관심이 고조되고 있다. 그리고 휴대폰과 PDA(Personal Digital Assistants), MET(Mobile Data Terminal)와 같은 휴대용 단말기의 사용이 일반화된 가운데 GPS(Global Positioning System)를 기반으로 하는 서비스들도 점차적으로 보편화되어 가고 있다. 이러한 변화에 따라 이동성을 지원하는 무선 단말기를 기반으로 한 Mobile GIS 환경에서의 위치 정보 활용은 큰 관심을 불러일으키고 있으며, 또한 이러한 서비스를 효율적으로 제공하기 위해서 위치 기반 서비스(LBS: Location Based Service)의 기술개발이 필요하게 되었다. 이 논문에서는 전력설비 고장복구업무에 LBS를 적용하기 위해 차량에 장착하는 MDT에서 모바일 지도 서비스가 가능한 Compact형 GIS 엔진을 설계하고 구현한 결과를 제시한다.

본 논문에서는 비젼 시스템과 후각 센서를 이용하여 모바일 로봇의 냄새 발생지 탐색 기능을 구현 하였다. 모바일 로봇에서의 비젼 시스템은 많은 연구가 진행되어진 센싱 방식이지만, 후각 기능은 새롭게 지능 시스템의 센싱 방식으로 주목 받고 있는 추세이다. 이에 본 논문은 이전까지의 연구에서 보여준 임베디드 시스템에서의 가스 센싱 기능 구현을 벗어나 신경망 알고리즘을 이용하여 냄새를 구별 할 수 있는 후각 기능을 구현 하였으며, 비젼 시스템과 후각 센서의 복합적인 알고리즘을 통하여 냄새 발생지를 탐색하는 방법을 제시하였다. 또한 이를 실험하기 위해 AMOR(Autonomous Mobile Olfactory Robot)을 구현하여 남새 발생지 탐색 알고리즘의 효용성을 입증 하였다.

생활 폐기물매립지의 효율적인 관리를 위하여 매립장 내 매립작업 진척상황과 매립작업 관리를 24시간 관리 체계를 구축하고 이를 안드로이드 기반 영상감시 시스템과 연계함으로써 시설 관리자의 상시 감시 체계를 완성하였다. 이는 매립 진척 상황과 침출수 관리를 관리사무소의 관제시스템에서만 관찰하게 되어 있어 기상변화와 위급상황에 대처능력이 전무한 실정이다. 이번 연구를 통해서 매립시설 운영자가 외부에 있는 경우에도 매립지 전경 및 침출수 상황을 관찰을 할 수 있도록 모바일 네트워크를 이용해 외부에서도 매립지 관찰을 할 수 있는 스마트폰 앱을 개발하여 24시간/365일 매립지 관찰을 할 수 있는 환경을 제공하고자 한다. 이러한 기본 개념들을 실제 안성시 생활 폐기물 매립장에 적용하기 위한 시스템 아키텍처 및 지능형 CCTV 컨트롤 시스템 스키마 등을 연구하였다.
