  • The study is about 'Dap-ho', a kind of men's coat in the early, and mid period of Joseon Dynasty. The study examined the kinds, color, and fabric of Dap-ho from "The Annals of the Joseon Dynasty". It also examined the characteristic, and the change of shape through excavated costume, and the period is limited until early 17th century. In "The Annals of the Joseon Dynasty", there is record of Dap-ho from King Sejong period to Gwang-hae-gun period. After 160 years, it appears again in King Young-jo period, and remains until King Soon-jong period. It was mentioned 168 times, from over 100 cases. There are 26 colors of Dap-ho from "The Annals of the Joseon Dynasty", and among them, green appears the most. Thin fabric, like Joo [紬], Sa[紗], and Cho[綃] was used often, and there are records of double layered, and cotton padded Dap-ho. The period when Dap-ho appears as excavated costume is almost the same as, "The Annals of the Joseon Dynasty" and disappears after the decease of Dae-ho Kang(1541-1624), and Sun-un Yun(1580~1628). After in this period, Dan-ryung, and Jik-ryung changes into double layered clothes, and Jik-ryung functioned as the underclothes of Dan-ryung, instead of Dap-ho. The excavated costumes of Hwak Kim(1572~1633), and Eung-hae Lee(1547~1626) proofs this. But Dap-ho was called 'Jun-bok', 'Dugree', Que-ja', and 'Dap-ho' until the later period of Joseon Dynasty.

  • In this paper, we implemented the FIPA-OS framework bundle and service agent bundle over the OSGi service platform in home-sewer platform. The FIPA-OS is the first open source implementation of the FIPA standards and is a component-based toolkit implemented in Java. The FIPA-OS bundle is composed of two bundles. One is the communication bundle such as RMI, IIOP, HTTP and ACC. Another is the agent loader bundle. Experiments are conducted on the service agent communication and loading by the agent loader bundle, and the proposed bundles are successfully installed, stopped, and uninstalled over the OSGi service platform.

  • The reliability of system is to become a important concern in developed industry. The controller based on the reliability is so important position. A reliable system is for system protection and human life by fault detection and control action against the transient condition of system. The aerospace system , nuclear reactor and chemical reactor are representative of a reliable system. This paper presents analysis of reliable system reliability, formal problem statement of optimal redundancy based on the reliability for a reliable system. And the problem is optimized by genetic algorithm. The genetic algorithms is useful algorithm in case of...

  • This paper presents the implementation of teleoperation control of an omni-direction mobile robot. The master joystick robot has two degrees of freedom to control the movement of the slave mobile robot in the Cartesian space. In addition, the whole teleoperated control system is closed by the force feedback. The operator can feel the contact force as the slave robot makes contact with the environment. Experimental results show that the teleooerated control with force feedback has been successfully implemented.

  • This paper describes an extension of Kaffe JVM which enables to extract runtime characteristics of a Java program. The runtime characteristics include frequency of method call instruction, ratio of library method call and ratio of method whose runtime is less than compile time. It also represents ratio of method called only once, polymorphicity of virtual call and distribution of method size called in runtime. This paper analyses runtime features of the SciMark benchmark suite using the extended Kaffe.
