Purpose Consumption behaviors of consumers have changed with the widespread use of the Internet and smart phones, and accordingly online marketing activities are becoming ever more prevalent. Yet, the domestic food-service industry has yet to offer an Omni-Channel order system that encompasses a online, offline, and mobile interface. Also, a multilingual menu ordering service for foreign tourists is not yet available. Therefore, if an order service system accessible online and offline which could provide multi-language services were implemented, the satisfaction of the service provider and domestic and foreign customers would be maximized. Design/methodology/approach By designing an electronic menu based on open an OS and providing electronic menus in offline stores, we have completed the design of a linked order system which would be available everywhere (online, offline, and mobile). The CMS was developed to integrate these three mediums and the entire operator was designed to receive basic information and statistical information about the merchants, or store operators. Also, a multilingual term dictionary containing menu information for foreign tourists was made into a database so that foreign tourists who are having difficulty in communication can use it more easily. Findings We have made it possible for customers to use the order service without distinction between online, offline, and mobile platforms, and have proved that it is a more efficient and convenient service for customers as well as operators. Nevertheless, as an initial model, the implemented system has limitations on the execution of the payment support method in the electronic menu board and in the management division of the CMS. In case of commercialization, it is necessary to make an alliance of efforts to attract initial franchises. Through further supplementation, we expect the online and offline connection-types martservice system will maximize the satisfaction of both operators and customers alike.

In this paper, a DS (Data Synchronization) server for mobile communication environments is constructed and the suitability and the performance of its operations are validated. The DS server provides a way to update the newest data and keep data consistency for clients (mobile devices). In addition, the DS server constructed in this paper supports various synchronization types, and detects all changes and conflicts. In case of data conflicts, the DS server resolves the conflicts according to the several policies implemented in this work. The DS server conforms to the OMA(Open Mobile Alliance) DS standard protocol for interoperability with other mobile devices and servers. In addition to the transmission-by record scheme proposed by the OMA DS standard protocol, the DS server constructed in this paper also provides the transmission-by field scheme for the enhancement transmission performance between the server and clients. In order to validate its operations, data synchronization between the DS server and the SCTS (SyncML Conformance Test Suit), the suitability validation tool provided by the OMA, is performed. The validation results show that the DS server constructed in this paper satisfies all of the test cases except the Large Object function. The Large Object function will be implemented later because the function is not needed for the personal information synchronization process which this paper aims for. Also, synchronization times of the DS server are measured while increasing the number of data and clients. The results of the performance evaluations demonstrate that the DS server is scalable, in the sense that it has not suffered from any serious bottlenecks with respect to the number of data and clients. We expect that this work will provide a framework for various studies in the future for improving mobile DS operations.

As widespread of using digital documents in various fields, control the usage of digital document is needed. So, Digital Rights Management(DRM) will become a key component of digital document system, but absence of proper digital document DRM system, there is a real risk to lose important information when a hacker achieved intrusion in important system. This paper designs and implements digital document DRM system based on OMA(Open Mobile Alliance) DRM model and OpenOffice. We considered being a digital document DRM system to contain appropriate solution of security and document compatibility.

복약기는 개인의 건강 증진 및 질병 예방을 위한 개인건강기기(Personal Health Device: PHD) 중 하나로 정해진 스케줄에 따라 약을 배출하는 기기이다. 복약기를 통해 수집되는 복약자의 복약상태(복약 여부, 복약 횟수 등)는 의료진 및 보호자에게 복약자를 관리하기 위한 중요한 정보가 될 수 있으므로 모니터링 서버에게 실시간 전송하여 의료진 및 보호자가 분석할 수 있도록 하는 것이 바람직하다. 이에 본 논문에서는 복약기 내에 탑재되어 사용자의 복약상태를 원격 모니터링 서버에게 실시간 전송하는 복약상태 전송 에이전트를 제안한다. 복약상태 전송 에이전트는 단말기 관리에 관한 산업계 표준인 Open Mobile Alliance(OMA) Device Management(DM) 프로토콜에 따라 복약 상태 메시지를 생성 및 전송한다. 복약 상태 메시지를 수신하는 모니터링 서버로는 OMA DM 기반의 상용 서버를 사용하였다. 이는 추후 본 논문의 복약상태 전송 에이전트를 확장하여 복약기 원격 관리 용도로 적용하기 위함이다. 본 논문에서는 제안된 복약상태 전송 에이전트의 구현 결과 및 모니터링 서버와 연동성 검증 결과를 제시한다. 검증 결과 제안된 에이전트는 복약기로부터 복약상태를 수집한 후 OMA DM 프로토콜에 따라 복약상태를 정상적으로 전송함을 알 수 있었다. 즉, 본 논문의 복약상태 전송 에이전트는 복약상태의 원격 전송뿐 만 아니라, OMA DM 을 준수하는 기존의 모바일 단말기 관리 서버들을 복약상태 모니터링 서버로 활용할 수 있다는 장점이 있다.

NC Soft will continue to dream of an entertainment innovation world where customers are connected through game and contents. NC Soft images an expansion in entertainment industry which open doors to the future of enjoy break through innovative online game and creative AI & IT technologies, focused on new business opportunities that are solely NC's own. This study starts with the implication on why focusing on exploration innovation and exploitation strategy at the same time in NC Soft is so challenging. NC Soft manages to their online & mobile gaming competencies in the long term and achieves their sustainable growth by incremental innovation (e.g. game planning, game programming, and graphic design). Also, for innovative success, pursuing exploration strategy is essential. NC Soft have built a strategic alliance spanning K-POP, digital contents platform, movie, and animation, sharing the connectivity of entertainment domains with major contents corporations. The findings of this study would also beneficial to entertainment and contents corporation executives and could provide some road-map on managing the dual challenges of exploration and exploitation implementations.
