본 논문에서는 이동로봇의 마찰력 보상을 위해 퍼지 외란 관측자를 설계한다. 이동로봇은 주행 바닥면에 따라 주행 특성이 달라질 수 있다. 주행 중 발생하는 마찰력은 비선형적인 특성을 가지므로 이에 검출할 수 있는 퍼지 관측기를 설계하도록 한다. 설계된 퍼지 관측기를 적용함으로써 주행 바닥 면의 상태에 따라 발생하는 마찰력의 영향을 최소화시킴으로써 주행 특성을 효과적으로 개선시킬 수 있다.

This paper is presented for the development of the brushless DC(BLDC) motor for the spindle motor of hard disk drives. To design the spindle motors for HDD, it is very important to consider the reduction of vibration and noises. To design the each parts and investigate the assemble of a motor, we need to calculate the press force and size variation according to the press force. If we design the each parts without the consideration of the size variation, we can not get good result of assemble and performance with exact size of parts. In this paper, we get the computer simulation results to verify optimal size and assemble.

In this paper, we propose a front-mounted single camera based depth estimation and robot localization method. The advantage of front-mounted camera is reduction of redundancy when the robot move. The robot computes depth information of captured image, moving around. And the robot location is corrected by depth information.

Efficient information flow is the lifeblood of any business. So, Ssangyong research center designed computerized systems to provide computer-based services and name it STIS-I. But the service system is for the retrieval of document written in Alpha-Numeric letters So, the interal technical information written in Korean letters are neglected. But the failing to make use of this literature can result in costly duplication of research. Here are introduced the retrieval system of the internal technical information (STIS-II) by COHIRES (Conversational Hangeul Information Retrival System) which was put into operation 1983. Also the functions of the COHIRES are described.

This study is aimed to investigate the application of DITA(Defense Information Technical stAndard) on the weapon information systems and defense management information systems in order not only to update the current DITA version 4.0, but also to develop SoS(System of systems) interoperability policy in the armed forces of Korea. For this study, 18 information systems were considered, their development products(System/Sub-system Specification, Technical architecture View, System Interoperability Test and Evaluation products) were reviewed and analysed. As a result of the investigation and analysis, it was found that the 44% of the DITA standard profiles were used for the development of the defense information systems. We conclude that DITA should be updated to be a minimal set so that all the defense information systems should be DITA-compliant. And it should be reviewed periodically to reflect the new information technology.

In the modern society, as development innovative technology consumers could access various information. It make consumers empower in the market, and information asymmetry problem were solving more and more. In the technical information, however, there are still information asymmetry because technical information is very difficult to understand, and those are related with professional knowledge such as financial information. This study used the dataset which was collected to track Korean consumers consumption index by KCA(Korea Consumer Agency) which included consumer's problem experience at financial field. The results are followings. Firstly, consumers want to get exact and important information to decide purchase or not and comparative information in technical information area. Secondly, age is the influence variable to experience more problems in technical information section. Thirdly, consumer's subjective financial competency is major influence factor to reduce problem experience.

Technical standards is directives for managing telecommunication network and also designing objectives for telecommunication network. The scope of technical standards varies from network environment of each countries but most countries compelled to observe the specified matters in technical standards. Generally, technical standards are the items extracted from national standards that must be followed by network providers. Technical standards is so very important to consist user's right and network operation that it is usually handled by national levels. In this paper, we analyze current status of technical standards for other countries and suggest some expected directions of technical standards schemes for domestic network.

Through analyzing papers on digital libraries and the contexts of usage of the term, ‘digital library’, this study investigates that the professional discourses about digital libraries regard them digital technologies. But digital libraries need to be recognized as socio-technical networks which are constructed by social interaction between heterogeneous elements. The study suggested that Social Informatics and a STIN(Socio-Technical Interaction Network) model should be applied to understand and analyze digital libraries as socio-technical networks.

상업출판사에 의한 학술정보의 무기화 및 독점화로 학술정보 유통이 일대 위기를 맞고 있는 가운데 누구나 자유롭게 학술정보를 이용하자는 운동이 활발하다. 이를 기술적 표준적으로 지원하기 위해 결성된 OAI에서는 OAI 아키텍쳐와 표준 프로토콜을 개발하였다. OAI는 프로토콜 표준화를 통해 메타데이터의 상호운용성은 크게 증진하였으나, 메타데이터와 전자원문 간 연계를 간과함으로써 정보자원 간 연계가 취약한 맹점이 있다. 본 논문에서는 OAI 아키텍쳐의 메타데이터와 전자원문 간 연계성을 개선하고 유사 자원으로의 확장성을 제공하기 위해, 국제표준 프레임워크인 OpenURL을 접맥한 개방형 학술정보 유통 아키텍처를 설계 및 구현하였다. 이를 통해 분산 환경에서의 정보자원 간 상호운용성 및 유사자원으로의 확장성을 제고하였다.

The purpose of this study was to survey and analyse the technical information flow and the status of information use of end user in the venture capital. The survey by questionnaire was used to collect data for the study and the SPSS program was used for analysiso of descriptive statistics. As the results of the study, the researchers of the venture capital thought that their research activities were important for the improvement of their company. They also suggested their opinion that the technical information was essential on research activities. The researchers wanted the manpower to take charge of gathering and managing technical information.
