최근 건강을 생각하는 사람이 증가하면서 걷는 사람들이 증가하고 있다. 걷기를 통한 건강관리에 대한 관심이 증대되면서 스마트 디바이스를 활용한 운동 관련 어플리케이션도 역시 증가하고 있다. 본인의 기록을 측정하기 어렵고 별도의 장비가 필요하던 과거와 달리 이제는 누구나 가지고 있는 스마트폰만으로도 자신의 운동을 효율적으로 자신의 운동을 관리할 수 있도록 하는 어플리케이션이 인기를 끌고 있다. 이러한 수요에 맞추어 스마트 상의 GPS센서를 이용한 걸음 가이드 시스템 '걸어보자'는 별도의 센서를 부착할 필요 없이 스마트폰에 기본적으로 포함되어 있는 GPS센서를 이용하여 사용자에게 추천루트를 제공한다.

In recent years, realistic contents technology such as virtual reality, augmented reality, and mixed reality has been spreading in travel and tourism industries, and hence there have been various smart tourism AR, VR contents developed. In the past, people mainly used books and Internet for travel, but the use of VR, AR and MR technologies will be used more for consumption of cultural leisure contents in the future. This study describes the Mixed Reality based Baekje Neungsa Cultural Heritage On-Site Guide System to accelerate smart tourism. In this study, the immersive mixed reality HMD was used to provide visitors with more intuitive and effective information about the historical, cultural and architectural values of Baekje Neungsa through virtual experiences. The cultural heritage on-site guide system module supports various Meta Data services and can be easily used for mixed reality content development by designating Meta Data scripts. This research can make contributions to the development of mixed reality based smart tourism contents.

Digital tourism is the digital support of the tourist experience before, during and after the tourist activity[1]. The GPS-enabled mobile phones provide location-based mobile applications such as tour guide and storytelling services. In this paper, we propose the smart tour guide service platform based on GIS and develop the mobile application to provide the smart tour guide service. The proposed smart tour guide service platform consists of CMS, the multi-modal navigation system, the tour attraction content creation and management system, the tour commodity creation and management system, the smart search system, and the user terminal. The smart tour guide application supports digital tourism in the pre-tour, during tour, and post-tour using the proposed smart tour guide service platform in the popular tourist attractions in Jeju.

스마트 거울은 다양한 IT기술을 활용하여 다양한 정보를 제공해 주는 거울이다. 그러나 기존의 스마트 거울은 단순한 정보만을 제공하거나 기존 정보 시스템에 답습에 그치고 있다. 본 논문에서는 기존 스마트 거울의 기능과 함께 사용자 맞춤형 스타일링 가이드 모드를 최적화한 Iot 기반 스마트 거울 시스템을 제안한다. 제안하는 시스템의 스타일링 가이드모드는 헤어 스타일링 방법 추천과 메이크 업 방법 추천, 퍼스널 컬러를 이용한 화장품 색상 추천 등의 다양한 기능을 제공하여 거울의 본질을 극대화 할 수 있도록 한다. 제안 시스템은 스마트 거울이 갖추어야 할 날씨 정보, 대중교통 도착정보, 길찾기, 일정 관리, 사진 촬영 등의 일반적인 기능을 제공한다. 이를 바탕으로 사용자에게 새로운 스타일링의 접근성과 활용성을 높이고, 다양한 미디어 정보를 통한 정보 활용과 외출 시간을 단축하는 새로운 스마트 거울 시스템을 제안한다.

소프트웨어가 대형화되고 복잡해짐에 따라 소프트웨어에 내재하고 있는 소프트웨어 허점(weakness)의 발생률이 높다. 이런 허점은 컴파일러에 의해 탐지되지 않고, 공격자에 의해 발견되기 쉽다는 특징이 있기 때문에 소프트웨어 취약성을 야기한다. 스마트폰의 확산으로 인해 다양한 종류의 스마트폰 앱이 개발되고 있다. 이에 따라 스마트폰 앱이 대형화되고 복잡해지고 있으므로, 여기에 내재하는 소프트웨어 허점을 사전에 예방하는 것은 중요하다. 본 논문에서는 안드로이드 앱을 개발할 때, 소프트웨어 취약점을 야기하며, 개발자가 간과하기 쉬운 소프트웨어 허점을 사전에 제거하고자 안드로이드에 특화된 시큐어 코딩 가이드를 제시한다.

In recent days, when the development in smartphones has made it common to operate objects by using them, this study aimed to present a guideline for the UI/UX designs for applications which are necessary for operating various objects through the wireless communication technology. To suggest the application guideline, existing object control application case studies were analyzed, and based on this investigation the object control application UI/UX design guidelines were proposed. This study classified the types of wireless connections used by smartphones (LTE, Wi-Fi, Bluetooth, NCF, RFID) and analyzed the necessary design factors for operating objects by each type. Based on such analysis, this study presented the design sequence, factors, and methods for the UI/UX guidelines of applications. First, the method of connection was selected; second, the control device was selected. This new direction for designing smartphone applications for operating objects will likely help systemize the design process and enable the user to operate the object more intuitively. In future research, case studies will be designed applying the guidelines suggested from this study.

Recently, much attention in building smart factory have been dramatically increased. Despite the growing interest in smart factory, few guidelines exist how to successfully build smart factory. The purpose of this study is to investigate successful cases in building smart factory in Korea. Drawing on the analysis of successful cases, we suggest the valuable guidelines and directions toward success of smart factory. As a result, in the case of large-size firms, it is an effective strategy that expanding from a model factory to whole factory for successful smart factory building. In addition, in the case of medium and small-size firms, it is an effective strategy that upgrading from low-level step to high-level step for successful smart factory building. Therefore, this study provides companies and government with specific and practical success strategies as well as industrial policy improvements.
