본 연구에서는 도로점용업무 현장점검 시 종이서류를 지참하는 등의 애로사항을 해결하기 위해, GIS 맵 정보와 UMPC, RFID 등 모바일기기를 이용하여 현장에서 활용할 수 있는 도구를 개발하여 적용하였다. 도로점용업무는 불법점용물 관리, 도로점용 허가신청에 관한 현장조사를 통해 적부여부 판단 등 현장 업무가 많음에도 불구하고, 기존 정보들이 종이로 관리되며 현장점검 체크리스트 작성 등이 수기로 이루어짐에 따라 시간 등 많은 비용이 소요되고 있다. 이러한 작업 중 점용물의 허가 적부 여부관리에 모바일 장비를 이용한 도로점용정보 현장점검도구 적용을 통해 현장조사 및 업무보고의 효율적 관리가 가능하다. 이에 본 논문에서는 GIS 맵 정보 및 건설인허가시스템에서 관리하는 도로점용정보와 UMPC 등 모바일 기기를 활용하여 도로점용업무의 효율성을 높였다.

This paper proposes a new forging work-in-process control system that guarantees independency of a specific device and provides cost-effectiveness. Until now, much research has been studied on improving the process productivity through efficient work-in-process or inventory controls. Especially, incorporating various IT technologies such as barcode, RFID, and image recognition has been done. However, those approaches cause many problems due to the characteristics of the forging work-in-process control environment. To overcome the limitations of the existing approaches, this paper proposes a novel forging work-in-process control system. The proposed system in this paper identifies and precisely manages positions of objects by using GPS information of smart mobile devices. Therefore, identification tags as well as specific devices for reading the tags do not been required. It resolves the problems of the previous approaches and enhances the productivity of the overall forging work-in-process control process.

In general the tickets are essential to buy goods and take services, which are used in various fields of modern society, and there have been several types of tickets such as a paper and an RFID chip. However, the conventional system has a problem like a loss of ticket or forge. thus there have many efforts to compensate the problem. In this paper, by improving the conventional system through the connection between a smart-phone with a server system, a smart ticketing system without paper tickets is proposed. The proposed system can support efficient services for managers and users in terms of timesaving and reliability. The proposed system can be applied in various similar fields requiring a ticket system.

The basic idea of IoT(Internet of Things) is interconnection and cooperation with a variety of things in real life such as Radio-Frequency Identification(RFID) tags, sensors, mobile phone, etc, through internet. IoT technologies which applied to these fields consist of sensor network technology and middleware, application. Currently, IoT technology is applied to various fields such as health care, home care, automotive, transportation, construction, agriculture, environment, food, and etc, based on its technologies. This paper focuses on discussion of the game planning method in IoT environment. In order to achieve this purpose, first, introduce the IoT technologies. Second, propose a game design elements and considerations in IoT environments. It can help for game developers by using IoT technologies.

Recently many researchers are keen interested in the concept of ubiquitous using mobile internet and RFID. Busan also plans to build a first U-city in the areas of port logistics, traffic, tourism convention, medical service. It is important to be accepted by consumers for U-tourism convention service adoption to determine the future growth potential. The purpose of this paper thus examines the effect of tourism contents on U-tourism convention service adoption using technology acceptance model.

As an absolute positioning system, iGS is designed based on ultrasonic signals whose speed can be formulated clearly in terms of time and room temperature, which is utilized for a mobile robot localization. The iGS is composed of an RFID receiver and an ultra-sonic transmitter, where an RFID is designated to synchronize the transmitter and receiver of the ultrasonic signal. The traveling time of the ultrasonic signal has been used to calculate the distance between the iGS system and a beacon which is located at a pre-determined location. This paper suggests an effective operation method of iGS to estimate position of the mobile robot working in unstructured environment. To expand recognition range and to improve accuracy of the system, two strategies are proposed: utilization of beacons belonging to neighboring blocks and removal of the environment-reflected ultrasonic signals. As the results, the ubiquitous localization system based on iGS as a pseudo-satellite system has been developed successfully with a low cost, a high update rate, and relatively high precision.

We developed a RFID terminal to voice guide the blind who have difficulties in reaching out to the pharmaceutical information. In this work, we used RFID technology to instruct the pharmaceutical information to the blind. The voice guidance reader was made to read the RFID tag attached to the drugs and announced the pharmaceutical information matching to the tag specific ID. We had the reader to obtain the pharmaceutical information from the ezDrug site operated by Korea Food & Drug Association. The voice guidance reader was fabricated as necklace type for the easy carry, and we added mp3 player as dual uses. ARM series Cortex M3 chip was used for the reader's core chip and low power MFRC523 chipset of NXP was used to construct RFID circuit. MFRC523 chip uses low power to meet the mobile application. We used VS1003B MP3 Decoder IC to make the voice generation circuit and CC2500 chipset for the wireless communication to the pharmaceutical information server. We also developed the system that can support ISO 14443A type and ISO 14443B type so that the system can be used to extend to various RFID protocols. Utilization of this system can conveniently convey the pharmaceutical information to the blind and reduce the drug abuse.
