  • This paper presents a high-speed pulse-based flip-flop with pseudo MUX-type scan compatible with the conventional master-slave flip-flop with MUX-type scan. The proposed flip-flop was implemented as the standard cell library using Samsung 130nm HS technology. The data-to-output delay and power-delay-product of the proposed flip-flop are reduced by up to 59% and 49%, respectively. By using this flop-flop, ARM11 softcore has achieved the maximum 1GHz operating speed.

  • The purpose of this study is to analyze housing expectations and housing preferences of college students' first purchased house for the future. Data was collected through self-administered questionnaires for this study and the samples consisted of 797 college students. This study found that college students preferred a high-rise apartments, a 20-24 pyung (66.0㎡-79.2㎡) house in housing size and relatively new house. The housing features and interior features that college students like to have and expected to have in the first residence were different. Their housing expectations were fairly realistic considering their affordability. College students preferred to furnish video and audio equipments, exercise equipments and ceiling fans. They generally preferred hardwood floorings and decorative moldings and expected to have built-in closet in their master bedrooms. They expected to have linen closets and large mirrors in their bathrooms. They preferred ceramic tile counter tops, wood cabinets, vinyl floorings in their kitchens and they also preferred to use kitchen as a utility.

  • The residential street is an area in which the residential function clearly predominates over any provisions for traffic. Therefore schoud it serve as a living space for the inhabitants. But in reccent times have motorists become lord and master through development and use according to the measure of automobile. As a result is being falling-off in the quality of residential environment particularly serious. This study have illustrated specially the environmental pollution (air pollution, micro climate. water balance and soil pollution) which the analysis of research data in foreign countrys. With that have this study proposed on the measures of the environmental friendly construction in residental street.

  • The computer network plays an important role in modern digital controllers within a safety system of a nuclear power plant. For the reliable and realtime data communication between controllers, this paper proposes a modified high-reliable MVB(multi-function vehicle bus) as a main control network for a safety system of a nuclear power plant. The proposed network supports the state-based communication in order to ensure the deterministic communication latency, and very fast network recovery when the bus master fails compare to the standard MVB. This paper also shows the implementation results using a FPGA-based testbed.

  • This study is to propose directions of waterfront planning about fishing village and harbor in East coast. Above all important waterfront-using in harbor, such as regional atmosphere and sea-scape are to investigate waterfront elements. For example, seaside park, harbor street mall, landmark, view point, promenade can be checked and design of waterfront may be possible to work out future harbor master plan. This study suggests that harbor of contemporary is to develop by regional waterfront characters. Accordingly, we analyze, it shows that the waterfront planning not only people of village but also visiting citizen is one of the important in developments about fishing village and harbor. As a results of this paper, we expect this research to be used as a valuable data in waterfront planning about fishing village and harbor.

  • Digital communication networks have become a core technology in advanced building automation systems. BACnet (Building Automation and Control networks) is a standard data communication protocol designed specifically for building automation and control systems. BACnet adopts Master-Slave/Token-Passing (MS/TP) protocol as one of its field level networks. Tn this study, we introduce a method of implementing bandwidth allocation scheme in the MS/TP protocol. The bandwidth allocation scheme improves the capability of real-time communication of the original MS/TP protocol. The bandwidth allocation scheme introduced in this paper can be easily implemented in the existing MS/TP protocol with a slight modification. In this study, we examined the validity of bandwidth allocation scheme using simulation models. The results from the simulation experiment show that the proposed scheme satisfies the requirements of real-time communication.

  • In this paper, we developed a Master Hand which has 20 potentiometer for getting grasping data of human hands, a Slave Hand which has 20 DOF and five fingers with servo-motors, and a controller for the 7 DOF Arm with Multi-fingered hands. And, we programmed a 3D simulation S/W which controls a Robot System with Multi-fingered hands. A developed Robot System showed good performance in the grasping of an object with known position and shape.

  • Machining information such as machined form and surface roughness accuracy is an important factor for manufacturing precise parts. To this regard, OMM(On the Machine Measurement) has been issued for last several decades to alternate with CMM. In this research, measuring system consisting of a laser probe is developed for machined form and surface roughness measurement on the machine tool. The obtained machined form accuracy is compared with reference one defined in CAD model. The measured surface roughness data is compared with measured master surface beforehand. Furthermore, using the pre-defined volumetric error map approach compensates the geometric accuracy of the machine tool. The overall performance is compared with CMM, and verified the feasibility of the measurement system.

  • 오늘날 국내 금융시장은 정택 및 규제에 대한 변화와 구조조정 및 인수 합병을 통한 금융회사의 대형화와 금융상품간의 복합 및 연계된 종합금융서비스를 제공하는 등의 급격한 환경 변화를 겪고 있다. 이러한 환경변화 속에서 금융 시스템 운영의 주체가 되는 마스터 데이터가 각각의 시스템에 개별적으로 관리되고 있어 이로 인해 금융 데이터의 품질 관리에 어려움이 생기게 되고 데이터의 중복 및 일관성에 문제가 생기게 되었다. 본 논문에서는 자크만 프레임워크를 활용한 통합 마스터 데이터 관리시스템을 제안한다. 이러한 마스터 데이터 관리를 통해 데이터 중복 및 데이터 정합성 보장, 시스템 연계간의 유연성을 확보하는 기대 효과를 예상할 수 있다.
