Big data, an important element of the 4th industrial revolution, is actively opening public data in public institutions and local governments. In the public data portal, everyone can conveniently search for data and check related data, but only those in ICT-related fields are using public data. Although data held by public institutions is open to citizens, it is difficult for anyone to easily utilize public data to develop applications. In this paper, data provided in open API format from public data portals has XML and JSON formats. In this study, we are a method of modularizing public data in XML format into a part that can be easily developed by linking it to a GUI interface. Based on the necessary public data, we propose a way to easily develop mobile programs and promote the use of public data.

In Smart mobile devices embedding big.LITTLE architectures, the conventional multi-core assignment scheme for user applications may incur wasteful energy consumption and long response time. In this paper, we propose a user experience assisted energy-efficient multicore assignment scheme. Our simulation results show that the proposed scheme achieves at 40% less energy consumption and at 20% less response time comparing to the legacy scheme.

본 연구는 이동 전화나 PDA와 같은 모바일 단말기를 이용하는 무선 인터넷 환경에서 데이터베이스 테이블로부터 Java 객체를 생성하여 이들 중간 형태인 XML 문서로 출력하고, 이러한 XML 문서들을 다시 XML 파서와 XSLT 처리기를 통해 무선 단말기에 적합한 마크업 언어 파일을 생성하여 단말기로 전송한다. 이를 통해 기존의 유선 인터넷상의 HTML 컨덴츠뿐만 아니라 데이터베이스 등 다른 정보들도 실시간으로 접근할 수 있는 장점을 제공한다. 향후에는 편리한 GUI, 매핑 규칙 선택 도구, previewer 제공 등을 위한 연구가 진행되어야 한 것이다.

최근 인터넷과 모바일 기기에 대한 소비가 확충되면서 인터넷을 이용하여 기존의 기기를 제어하는 기술을 필요로 하고 있다. 이에 따라 본 논문에서는 자바 애플릿으로 GUI를 구성 한후 웹브라우저와 TCP/IP틀 통하여 기기를 제어하는 시스템을 설계하였다. 인터넷을 통하여 기기를 제어하는 기술은 그 응용 분야가 홈네트워크, 텔레메틱스등 넓기 때문에 지속적인 연구가 필요할 것으로 보인다.

With the spread of mobile phones and wireless networks, medical imaging needs to be accessible outside the hospital for patients. We develop the mobile PACS platform that allows doctors or patients to store, search, query and transfer medical images for their convenience. This system is a mobile based platform that patients DICOM images can be viewed from the hospital PACS server, then they can be converted according to smart standardization. For this, we designed the platform to transfer the data between PACS, mPACS and users. Also we suggest to use DICOM transformation processing to display DICOM images in PACS server.

This paper is construction on ontology_based mobile Customer Relationship Management system for efficient customer information management and analysis of medicine center. As using ontology technique, we support medicine service at grade according to quality and healthy of the customer based customer information. Proposed CRM system provides medical information and seminars to whom are necessity. For this, priority retrieval and similarity retrieval are able to be in the personnel order and the regional.

소비자들의 욕구 충족을 위하여 생산 제품이 다양해지고 있는 상황으로 소비자 맞춤형 생산이 이루어지고 있으나, 제조 현장에서는 운영자 및 작업자가 신속하게 제조 작업을 할 수 있는 시스템이 필요하다. 그러나 일반적으로 HMI와 같은 별도의 GUI 장치를 통하여 생산 내용의 변경이 가능하나, 작업자들은 이를 조작하여 PLC를 통한 생산에 적용하는데 많은 어려움을 겪고 있다. 본 논문에서는 단말기가 필요하지 않는 QR 코드를 기반으로 모바일 기기를 통하여 키오스크 기능을 제안한다. 제안 시스템은 모바일 디바이스를 통하여 검증된 생산 사양만을 선택할 수 있는 키오스크 화면을 구현한 것으로, PLC와 연동하여 즉각적으로 소비자가 필요로 하는 맞춤형 주문 생산이 가능할 것으로 기대된다.

As the price-performance ratio of embedded PCs improves, the benefits of the PC-Fi can be maximized by designing an embedded PC-Fi system. In this paper presents the design of an embedded PC-Fi that can be manipulated by a remote controller based on mobile devices such as smart phones or tablets. Additionally, an interactive control system and its GUI, through which the user can select and play music as they like at ease, are presented. The case that a large amount of music is stored in the PC-Fi system requires a function allowing the user to easily select the music they want to listen to. In order to implement this function, a DB containing detailed information of each track can be used to find the location of the desired music with keywords provided by the user. In this proposed system, the embedded PC-Fi system and remote controller are mutually connected via a WiFi network, and more than one user can remotely control the embedded system with their own mobile device.

IStorage is a technology, which can use resources of server PC by using Android Phone supporting wireless internet access. IStorage utilizes resources of server PC through WebDAV protocol. And with GUI interface, Users upload their resources to the server PC and They can perform various kinds of works like Opening, Searching, Deleting and Downloading files. Since it is possible for them to use resources of server PC as if they are originally stored in their mobile devices, there is no limit on using the functions such as watching movies, listening musics and opening document files in real time. We expect this study can to overcome the limitation of storage space and also be a useful technology in the smart phone market.

Datum point for displaying location and altitude of point has being advantage usefully in various measurement parts. However, datum point has been increasing loss cases owing to weather changes and stratum changes and neglecting meaninglessly. In this paper, we design and implement a multi electronic measurement system monitoring software with functions such as include maximize utilization of existing measurement datum system as well as collected various environment data and detection stratum changes of surround area. Proposed software is implemented to support that reusability and extensibility of software using object oriented modeling method. Our software supports a GUI for electronic measurement datum point administrator as well as for web user and mobile user. Our system can support a graph GUI for various data analysis and reposition in realtime to database that measured location information and various sensing information to prevent loss of electronic measurement datum point and to detected stratum changes. In addition, we include a QR code and RFID recognition function. Finally, we suggest performance evaluation result to confirm stratum changes detection and GPS location error rate.
