This paper proposes a method using the multiple threshold regions in the image preprocessing procedure for container identifier recognition system. The multiple threshold regions are set by considering the container image characteristics and used as the candidates for the final one, The image is transformed to black and white images using these threshold regions, then labeling, panelling and panels merging are executed for each candidate, respectively. Finally the best threshold region is selected through this procedure and the character region can be extracted. Applying the similar method the noises are removed and the characters of identifier are segmented from the extracted region. In the experiments with 162 different images the success rates for extracting of the character region and segmenting the characters are 99.04% and 98.09%, respectively.

A Unique Feature Identifier(UFID) is a way of referring to a feature, generally representing a tangible feature in the real world. In other words, a UFID uniquely identifies the related feature in the database and is normally used to link two or more databases together. This paper presents a UFID system aiming at the internal uses for National Geography Institute(NGI) as well as external uses for National Geographic Information System(NGIS) generally to link datasets together. The advantage of the proposed type of UFID lies in the meaningful nature of the identifier in providing a direct spatial index - administrative area and feature code. The checksum character proposed in this research is designed to remove any uncertainty about the number being corrupt. It will account lot digit transposition during manual input as well as corruption in transfer or processing.

As the results of the information project, manufacturing of the digital map and various thematic maps of the national land has been completed. Furthermore, it is necessary to organize a systemized management system, which can control and utilize all artificial features (e.g. buildings, roads, bridges etc.) as well as natural geographic features (e.g. rivers etc). Howener, it has difficulties in managing NGIS as a unified system, because of the discordance of DB of each geographic management organizations. Therefore, this study has been conducted to apply to the system and method providing geographic UFID that can be a key in order to managing, searching and utilizing geographic and artificial features and that makes it be able to estimate the location with the only identifier. Moreover, the system and method, providing geographic UFID, applies to systemized management of NGIS DB as well as consistency of information.

The pendulum is a SIMO(Single-input multi-output) system that both angle of pendulum and position of cart controlled simultaneously by one actuator. In this paper, propose a hybrid neuro-controller to apply to pendulum system. We design the conventional optimal controller and the neural network as a identifier, which can identify the uncertainty of plant not modeled, respectively. Then we combine them into a novel controller, with a structure that the error between plant and identifier is added in conventional optimal control input Finally, the paper shows the validity of the proposed controller through computer simulations and experiments.

In this paper we propose the resolved motion controller using a neural network for a robot manipulator. Neural identifier designed by a neural network is trained by using a feedback force as an error signal. The identifier approximates the output of a unknown nonlinear system by monitoring both the input and the output of this system. If the neural network is sufficiently trained well, it does not require either strict modelling of the manipulator or precise parameter estimation. The effectiveness of the proposed controller is demonstrated by computer simulation using a two-link planar robot.

With the rapid development of information technology and internet in these days, resources of knowledge information have been digitalized and distributed on the internet, However, the location of digital content and a change of content have generated problems for users access and services. In line with this regard, the research on the identification of digital content utilizing standardized identification system and distribution system is necessary. This study intends to contribute to the implementation of information system based on standard digital identifier for the effective management and safe distribution of digital contents. This study first tries to survey SDI outline, practical application case and distributed business model and to analyze information distribution status Finally, this study tries to draw up a plan for the establishment of KISTI's SDI. content identification system, content distribution system.

Smart Device Communications using the development of anti-theft system for vehicles have been investigated. because Progress of Smart Device If someone get the Key for Vehicle theft, he can be easily stolen vehicle. We thought about the concept of dual security devices. Using vehicle's identifier ID of CAN, when Comparing Smat phone identifier ID value and identifier ID received from the Can in the Head, If the same ID is compared. At this point after the activity of the vehicle's ACC On/Off the system allows the vehicle's ignition.

This study proposed an integrated management system model of researcher identifiers using the ISNI(International Standard Name Identifier) that can prevent duplicate issuance of identifiers and can be used to reorganize the authors' information. We looked at the metadata structure and management system of the ISNI that can be applied in various fields among identifiers. And we have designed the integrated ID system and system model that can manage the identifiers issued by each institute based on the ISNI. This model consists of data structure layer, platform layer, application layer, management and security layer (4 layers) and we have presented some of the key features and issues to consider when managing the integrations.

Recently, due to the development of the mobile communication system and communication technology, a communication paradigm changes from human-to-human(H2H) communication to machine-to-human(M2H) and machine-to-machine(M2M) communication. The machine means a device with networking capabilities Also, if M2M services will be activated, we can expect that many M2M devices connect to mobile communication networks, which leads to the lack of M2M identifier to identify a M2M device in mobile communication system. Therefore, this paper proposes the group identifier based M2M identification scheme to identify many M2M devices in mobile communication based M2M service network. In the future, the proposed M2M identification scheme can be utilized as a way to solve the shortage problem of M2M identifier.
