Modern financial services go beyond the stage of internet banking, and new concepts of financial transactions such as Internet of Things, mobile banking, electronic payments, and fintech have emerged. As a result, banks are less influential in financial transactions, and changes are being demanded. In the present era, the basic business of banks has decreased, and it is transforming into a space where both consumer finance work and reside. The bank office stands for the brand image of the bank, and it is represented by trust with customers in the basic business of financial transactions, and the rise in real estate value is a natural social phenomenon due to the nature of the location and location of real estate owned by the bank. The business method and space of the bank office that meets the new paradigm of the modern society is an inefficient space only for the convenience and rest of consumers, but it must be used as a variety of spaces suitable for the region to increase the functional value of the bank office. Through this study, as a convenience space for consumers, various service facilities should be introduced to understand the characteristics of the region as a convenience space for consumers, and various service facilities should be introduced to meet the needs of consumers, and the bank office should be improved as a complex service space for local residents.

Nowadays, due to the popularization of mobile phone, the functions and using manners of mobile phone have been varied. According to Korea National Statistical Office, the numbers of domestic mobile phone user were 30 million at the end of March 2002. A survey was conducted to investigate the various using manners of mobile phone, especially the young ones from 15 to 28 years old. Two hundred and sixty people participated in this study. According to the result of this study, text messaging was one of the major functions of the mobile phone for the young people. Also, continuous and repetitive use of small key pad of mobile phone for text messaging could cause the repetitive strain injury on hand, especially fingers.

The computer was only used to calculate and solve the mathematical problems, to send the simple data, and to exchange the text based informations in the early 1990's. But nowadays, computer technology give us the chance to exchange digital goods and services, etc. And more, computer and computer based systems can be applied everywhere, for example, it can be used at office, at home, and at school. Most of all, one of the remarkable changes is the development of mobile industry, which can be applied anywhere and anytime. So, this study focused on the current situation and promotion plans of the mobile industry. Mobile is based on the IT, IT and mobile technology are the foundation stone of ubiquitous computing environments. Accordingly, this thesis analysis the meaning of ubiquitous, the meaning and roll of mobile industry. With the analysis of this, the conclusion is that to develop and success the new business model at home and overseas, the cooperation of government section and industry section is the most import thing to make it out.

In this paper, we introduce an ADSRC(hdvanced DSRC) OFDM packet communication system which has been developed by ETRI. The ADSRC system is targeted to provide high terminal mobility, high data rate and seamless service in roadside environment for mobile office services. We discuss the requirements of the ADSRC communication system for mobile office services, and the system design specification to meet them with regard to air interface. The ADSRC packet communication systems consist of the MAC processor block, the OFDM packet modem block and the RF block. The MAC processor block handles medium access control and the test. The OFDM packet modem transmits data packets at up to 24Mbps adaptively and recovers the data from RF block. We describe the ADSRC packet communication system architecture and the ADSRC system protocol.

The proliferation of devices such as tablets and smart phones, which are now used by many people in their daily lives, has led to a number of companies allowing employees to bring their own devices to work due to perceived productivity gains and cost savings. However, despite many advantage, security breaches (e.g., information leakage) can happen for various reasons (e.g., loss or theft of devices, and malicious code) and privacy breaches can happen by using personal devices for business. We should carefully scrutinize security threats in this area. We present the security threats analysis and the technical approach in this area, and discuss privacy threats and countermeasures.

모바일 데이터 사용자의 수는 향후 5년 안에 전체 모바일 가입자의 70%에 육박하여 전 세계적으로 6억명을 초과할 것으로 예상되고 있으며 2005년에는 데스크탑 인터넷 이용자의 수를 초과하는 10억명에 이를 것으로 전망된다[3]. 그러나 현재의 휴대폰 기반 인터넷 서비스는 지난 80년대 문자 기반 PC통신 서비스를 이용하는 수준 정도이다. 또한 인터넷으로 연결되었다고 하더라도, 현재의 무선 인터넷 서비스는 때와 장소를 구분하지 않고 사용하기에는 서비스 제공 능력이나 모바일 업무에 맞는 어플리케이션 개발이 상당히 부족한 상황이다. 이러한 측면에서 모바일오피스(Mobile Office)는 누구나(AnyPerson), 언제나(AnyTime), 어디서나(AnyWhere) 회사 정보에 접근하고 공유하며 업무에 적용할 수 있도록 시급히 구현되어야 할 대상이다. 본 논문에서는 외근 위주의 영업사원과 사내 직원간에 보다 효과적인 커뮤니케이션이 필요한 보험업을 중심으로 특화한 모바일 오피스 솔루션의 기반을 제시하고, 이것을 모바일 환경과 일반 PC 환경 그리고 PDA(Personal Digital Assistants) 환경에 맞추어 각각 구현하였다.

For low-power high-frequency LED driver applications in small form factor mobile products, a high-efficiency boundary conduction mode tapped-inductor boost converter is proposed. In the proposed converter, the switch and the diode achieve soft-switching, the diode reverse-recovery is alleviated, and the switching frequency is very insensitive to output voltage variations. The circuit is quantitatively characterized, and the design guidelines are presented. Experimental results from an LED backlight driver prototype for a 14 inch notebook computer are also presented.

Compared to nomadic and fixed relay stations, vehicle-mounted mobile relay stations show different characteristics caused by the time-variant topology, due to their mobility. Especially, a relay mounted in a vehicle is differentiated from nomadic or fixed relay by the restricted distance between the relay and associated mobile station and the variable density of relay deployment in a cell. In this paper, we identify the characteristics of vehicle-mounted mobile relay stations and provide some parameters that highly influence the performance of vehicle-mounted relay. Through simulation, we measure the effect of relay density, zone ratio, relay transmission power, and frame transmission mode on the performance of vehicle-mounted relay. The results show that the performance of vehicle-mounted relay is highly susceptible to the above vehicle-mounted relay-specific parameters.
