산업현장에서 로봇의 사용이 크게 늘게 됨으로서 로봇의 배치와 움직임의 조정을 효율적으로 하는 것이 중요해 졌다. 이를 위해 가상의 공간에서 시뮬레이션 하는 오프라인 프로그래밍이 사용되고 있다. 본 논문에서는 오프라인 프로그래밍 기반의 시뮬레이션 엔진을 설계, 구현하였다. 복수의 로봇 시뮬레이션이 정적/동적인 상황에서 이루어 질 수 있도록 이벤트/사이클 혼합 방식을 사용하였다.

In this paper, an active noise controller for a communication headset was designed. In a communication headset, there exist information signals such as voices from the end for the communication line as well as also, undesirable noises with are induced by external noise sources such as engine noises. Therefore, it is necessary to reduce the external noises for clear hearing of the communication signals. This problem was solved by robust H(sub)$\infty$ controller to reduce noise and a compensator for information signals The designed controller was implemented using TMS320C31 DSP Op-amp, and several experiments were performed to verify its performance. The results showed that the controller reduces the undesirable noises sufficiently, while communication signals are not reduced.

As internet use is being generalized central of WWW(World Wide Web) service of multimedia based recently, we could acquire many informations that exist to all over the world's computer network .Therefore, picking up of information became important problem before that internet is generalized, but it is risen to important problem to acquire correct information rapidly on modem society that use of internet is generalized. This paper designed internet search engine and understand structure of internet search engine drawing URL that is optimized, and secure embodiment technology using Java that is language of object base. Search engine that proposed in this paper maintained user's the convenience by offer keyword search, and simplify user interface And although quantity of searched information site is few, search engine show that the bad link rate of searched result is improved compare with existent domestic manufacture search engines.

This study focused on design and implementation of Mobile 3D Bluetooth Engine based on OpenGL-ES. In Mobile 3D network game so far, there is a form the mainstream of wireless internet game using WAP and VM. But, VM game are popular because of an excessive communication expense problem for this mobile network game that occur when connect to wireless internet as point out to problem by it, that is, stand-alone game are very popular. This study introduce a mobile 3D Bluetooth Engine which is based on mobile 3D standard using OpenGL-ES to solve a mobile network game generally that occurs when connect to take pleasure a wireless internet from some people into a short distance.

Context-aware intelligent services are essential in ubiquitous computing and intelligent robots environments, which make decisions on which services to start with the consideration of surrounding contexts. In the ubiquitous and intelligent environments, context-aware service engines should be light-weighted due to the resource restrictions on the devices. This paper presents a context-aware service engine which is designed for light-weighted devices. The context-aware service engine has been designed with special attention to improve the execution speed and to minimize the memory requirement.

As the interest on healthcare area in pursuit of well-being, health etc is increasing, u-Healthcare service that can monitor the condition of oneself's health anytime & anywhere is getting an attention. The existing health information system is consist of structure supporting the storage of estimation value and just simple display. But this needs to get a harmonious interaction to provide the health information exactly and speedily for efficient condition confirmation and diagnosis in health information system, In relation to this, this study proposed the developmental contents about visualization engine providing the beuer information discrimination and more user-friendly in various service of u-Healthcare.

Fishery and shipping industry are ones of the important industries for the Republic of Korea, and the education of competent technicians is a essential-important factor for the further development in these fields. To this end, curriculum for the fisheries and/or merchant marine high schools are rearranged to meet the industrial needs and social change. In this study, the existing goal of education is rearranged inclusively to meet the further development and the curriculum to realize the goal. The departments are reorganized into nine ones by establishing new two. They are Department of Refrigeration Mechanical Engineering and of Automated-ship Operation. Four departments of existing seven-Department of Fish Aquaculture, of Fish Processing, of Marine Engine and of Marine Communication-are renamed into Department of Aquaculture, of Food Processing, of Power Mechanical Engineering and of Electronic Communication respectively. The remaining three departments- Department of Fishing Technology, of Self-managing Fisheries and of Navigation-are unchanged. The specialized subjects are revised as follows; (1) The existing seven subjects especially prepared for the fisheries and/or merchant marine high schools are changed into the common subjects for all the vocational high schools. They are Food Science, Food Hygiene, Food Processing Machinery, Air-conditioning Facilities, Welding and Piping, Communication Law and Introduction to Computer. (2) Two subjects are newly established: Refrigeration Mechanical Engineering and Automated-ship Operation. (3) Four subjects are disused : Sea Training, Fisheries Law, Canned Food and Practice in Communication. (4) Introduction to ship, to Marine Engine and to Marine Communication are merged into Introduction to ship. (5) The compulsory major subject is fixed as Introduction to Fisheries for the fisheries high schools and Introduction to shipping Industry for the merchant marine high schools.

Intelligent remote learning system is a system that incorporate communication technology and others : a database engine, an intelligent tutorial system. Learners can study by themselves through the intelligent tutorial system. The existence of a communication, database and artificial intelligence enhance the capability of IRLS. According to Parsaye, an intelligent databases should have the following features : 1) Knowledge discovery. 2) Data integrity and quality control. 3) Hypermedia management. 4) Data presentation and display. 5) Decision support and scenario analysis. 6) Data format management. 7) Intelligent system design tools. I hope that this research of framework for IRLS paves for the future research. As mentioned in the above, the future work will include an intelligent database, self-learning mechanism using neural network.

The recent push for healthcare reform has caused healthcare organizations to focus on ways to streamlined processes in order to secure high quality care as well as reducing costs. Healthcare enterprises involve complex processes that span diverse groups and organizations. These processes involve clinical and administrative tasks, large quantities of data, and large number of patients and personnel. We propose the mobile-based workflow system of passable communication as an important factor in the B2B healthcare. Based on the above proposal the workflow system of business process was designed and implemented on the basis of Java, UML and XPDL.
