This study proposes strategies for economic development through mobile in Africa where mobile emerges as an infra to solve socioeconomic problems. It analyzes economy and ICT industry in Africa and studies several cases that are utilized in agriculture, finance, education, and healthcare. It also examines economic development theory and the impact of broadband on economic growth and development. It is necessary to leapfrog to mobile to achieve an information society and a compact industrialization based on ICT because fixed-line is very poor and expensive in Africa. Building a mobile broadband infra, supporting a dissemination of low-end smartphones and a government's support for mobile contents are necessary to achieve a leapfrogging development through mobile in Africa. The findings of this study provide additional insights for Korean ICT companies to consider a business in Africa.

The purpose of this paper is to study building and maintaining consumer trust in mobile contents for tourism and travel in perspective of public sector. Mobile contents services are increasing rapidly. Tourism contents in mobile services are non profit business model in an early and immature stage toward the ubiquitous era. Non-profit organization plays a role as service provider through Internet and wireless telecommunication in an information-intensive and network-oriented environment. This article is proposed nonprofit organizations as tourism contents service provider to identify a conceptual framework that can build continuous trusted mobile contents under ubiquitous environment according to developing and maintaining stage. The results based on the focus group interview methodology highlights a conceptual foundation for service providers in nonprofit domain.

Freight and passenger transport operators must converts the operation records of digital operation recording device (Digital Tachograph) that is mounted on their vehicle in a certain format, and report them to governmental agencies. However, for most of the individual carrier who cannot access a computer environment easily and are not familiar with the use of computer, it has given a big inconvenience to them because the procedures for entering the data obtained from the operation are so complicate. Therefore, in this study, a mobile system for converting the operation record file to request form of a government agency is designed and developed, so that the converted file can be submitted to the government agency in a simple way through the personal mobile device. By entering the data obtained from an actual operation recording device into the system, converting the data in the proposed algorithms, and checking the contents of the converted file in data viewer, it was confirmed that the proposed functions is working properly in the system.

Due to the mobil-centered lifestyle following the wider use of Smartphones, Mobile services, including mobile banking and mobile shopping business have increased rapidly. Also with the emergence of "Fintech", which finance combined with technology, IT based financial market is going to be highly promising. In this trend, interests mobile credit cards are increasing. But diffusion of the mobile credit card services is still in the low level. In this situation, to identify factors that influencing satisfaction and continuous usage intention on mobile credit card, this study applied innovation diffusion theory (IDT) and post acceptance model (PAM). To conducting this research, survey data were collected, and we used SmartPLS to analyze survey data. As a result of the study, perceived easy of use, image, compatibility and facilitation positively affect user's satisfaction in mobile credit cards and that such satisfaction have a positive impact on continuous intention to use. The facilitation influences user satisfaction more strongly for those who use mobile credit cards more than plastic credit cards. Also, perceived of use and image influence user satisfaction more strongly for those who use plastic credit cards more than mobile credit cards. It is expected that this study can be a guideline for credit card service providers and policy makers to invigorate mobile credit card business. Also it worths as a early-stage research on Fintech-related studies.

In this study, we propose a method to improve the guideline for accessibility of mobile applications based on the results of manual evaluation of 8 mobile online shopping applications which are widely used in Korea. 13 items of mobile online shopping application were found to have low compliance rate, and 5 items such as response time control were observed and there was no corresponding items. In the current mobile application accessibility guidelines, it is necessary to delete the check items that are not relevant or meaningless, and to provide additional logical items such as logical ordering and form creation, and to improve the accessibility of mobile applications, The government should make efforts to develop and disseminate the development guide, and to resolve the digital devides.

소셜 네트워크 서비스(SNS: Social Network Service)는 사용자들 간의 정보공유 및 관계형성을 위한 Web 2.0 기반 기술로써, 관계를 통해 형성된 사용자들 간의 상호작용을 지원하는 서비스이다. SNS 기술은 개인들 간의 관계 뿐 아니라 공공부문의 서비스의 제공자인 정부부처 및 공공서비스 제공기관들과 사회구성원들 간의 관계형성을 위한 기술로써 각광받고 있다. 최근에는 모바일 기술의 발전에 힘입어 트위터, 페이스북과 같은 SNS 이용자가 빠르게 증가하고 있으며 그 활용범위 또한 개인 사용자들 간의 정보공유에서 기업과 고객, 공공과 국민의 관계까지 확장하고 있다. 본 논문에서는 SNS가 공공부문의 서비스 제공을 위한 수단으로 활용한 사례를 통해 요구되는 기술을 제안한다.

최근에 정부는 IT839 전략을 발표하여 IT산업의 새로운 서비스 도입과 신규 수요 창출에 역량을 집중하고 있으며, 신규 서비스로서 RFID/USN도입을 강력히 추진하고 있다. 이런 추세에 발맞추어 본 논문에서는 기존 passive RFID의 단점을 개선한 RFID/USN의 동향을 알아보고 USN활성화를 위한 범용 대국민 서비스, 공공 인프라서비스 등의 킬러서비스 드라이브 전략을 제시한다. 또한 이런 서비스들을 제공하기 위한 실용적인 USN구조를 설명한다. 현재 우리나라의 휴대폰 보유율은 3000만대를 넘어섰다. 이 모바일 휴대폰 각각은 훌륭한 USN단말기 역할이 가능하기에 모바일 휴대폰을 기반으로 하여 적은 투자로도 구축가능한 AnyTime, AnyWhere USN망을 제안한다.

In general, existed kiosk using touch-screen based kiosk system has been used by only single user, so that multiple users to access this kiosk need to provide a lot of waiting time and maintenance costs. To solve this problem, the framework design based on Bluetooth profile for kiosk servers is presented. The proposed kiosk system can be more efficiently used in theater, train station, bank, government, and public offices by using Bluetooth module and AP in mobile system such as smart phone.

인터넷과 모바일 기기의 발달로 사용자는 언제, 어디서나 온라인 쇼핑 및 인터넷 뱅킹 등을 스마트폰 앱으로 결제를 하는 시대가 되었으나, 모바일 뱅킹 앱 경우에도 다수의 앱을 탑재하는 불편이 발생하여 이를 개선 하고자 하는 필요성이 대두되고 있다. 그리고 정부는 핀테크 산업을 국가의 미래 신성장 동력으로 인식하고 핀테크 산업 활성화 및 핀테크 기업 지원방안 마련에 적극 나서고 있다. 그러므로 핀테크 기업이 각 금융회사와 개별적으로 협약을 맺어 금융 데이터 및 서비스에 접근 하여야 하는 앱 기반 위주의 프레임워크는 상호운용 및 유지보수에 문제점이 점점 가중되고 있으며, 이를 해소하기 위하여 표준화된 개방형(Open) 플랫폼이 기술적 방안으로 권고되고 있고, 국내 ICT 기업들의 핀테크 비즈니스에 참여를 독려하기 위하여 개방형 핀테크 플랫폼의 정보보호 지침이 마련되었으며, 이를 기반으로 국제표준이 ITU-T SG17에서 승인되었다.

최근 모바일과 테블릿 등의 휴대용 디바이스들 활성화로 인해서 어플리케이션의 종류가 확대되고 누구나 어플리케이션 개발에 쉽게 어플리케이션 제작을 할 수 있어짐에 따라서 개발 조직의 소규모와 개인 개발자들의 활동이 늘어가고 있다. 하지만 현재 앱에 관련된 소프트웨어의 개발 방법론은 많지 않다. 그래서 이 논문에서는 1)소프트웨어의 보안개발주기의 최소화를 통해 개발자들에게는 보안가이드 라인을 제공하고 2)소규모의 개발자들이 주어진 보안개발 방법론을 따라 품질과 보안성을 향상하고 3)정부나 앱스토어의 검증성을 높여서 고객이 신뢰하고 검증된 모바일 어플리케이션을 사용할 수 있게 하는 것이다.
