R In today's competitive and global business management, Concern of an enterprise is to strengthen the core competency and improve it's internal business process. Therefore, Interest in BPM(Business Process Management) has grown rapidly. BPM is recognized as best solution to meet the needs of organizations that seek the cost down, integration of information, reducing of risk, improvement of productivity. In the past, the company have usually made huge investments in knowledge management systems which are based on repository keeping tacit knowledge. But this paper shows feasibility of implementation of business process-based knowledge management system that could link knowledge with business process. From an academic point of view, Although There could be several ways to build the business process-based KMS. In this paper, when BPM project and KMS project were started at the same time, the way of how to provide workers with task-related knowledge was discussed. As an case study, an estimate process of H company was analyzed and process modelling was carried out and conceptional architecture framework was depicted.

Recently, business environments have been changing quickly. To establish competitive advantage, most enterprises have been using information systems such as Enterprise Resource Planning (ERP), Supply Chain Management (SCM) and Customer Relationship Management (CRM). Many consider Business Process Management (BPM) a new innovative solution for enterprise-wide processes. As the BPM system is used more widely and matures, new techniques and functions will be developed by commercial vendors. However, they mainly focus on correctly executing process models, and user convenience has not been considered. In this paper, we have developed a new method of designing business processes, which provides users with an easy modeling interface. The method is based on version management. Version management of a process enables a history of the process model to be recorded. In order to prevent wasted storage, not all of the process versions are stored. An initial version and changes to each process are stored by automatically detecting changes. Our method enhances the convenience of the modeling business processes and thus helps the process designer. A prototype system is presented to verify the effectiveness of our method.

To overcome the limit of the time-domain based channel estimation caused by the ADC speed, this paper present a new BPM-UWB receiver where the channel estimations and the compensations are digitally performed in the frequency domain. We theoretically show that the channel estimation can be accomplished by exploiting the periodicity of a training sequence consisting of finite number of pulses. We also present the digital receiver structure to implement the proposed system and derive its BER performances. Through computer simulations, we show the proposed receiver can dramatically improve the BER performances due to the incorporation of the estimated channel frequency response.

In Ubiquitous computing environment, as the requirements of various services and combination of personal digital assistant are increasing, the standards and technologies have been developing all over the world. Also, ubiquitous government is planning to provide seamless service therefore, the demand is very high about infrastructure of service combination which connects various governmental systems. As a result, it is required that the Service-Oriented Architecture (SOA) and technical developments which combine various services, devices and terminal accepting to use seamless service convergence in ubiquitous computing environment. In this paper, I suggest to combine for a single web service to use Business Process Management (BPM). It can be expected to develop technologies efficiently and effectively by reusing web services, and reducing mistakes and faults of the development.

본 논문에서는 업무할당방식이 효율성에 미치는 영향을 분석함으로써, BPM 업무환경에서 효율성을 증진시키기 위한 방법론을 모색한다. 이를 위해, 업무할당방식을 프로세스 실행시에 사용자를 할당하는 동적할당과 프로세스 모델링시에 결정하는 정적할당으로 구분하여 BP효율성 관점에서 상호 비교한다. 지금까지 이런 업무 할당방식이 업무효율성에 어떤 영향을 미치는지에 대한 연구가 없었으며, 본 논문은 cycle time 척도에 대해서 이들 업무할당방식을 비교 분석한다. 이러한 비교 분석의 결과는 상용 BPM를 도입하여 운영하는 기업에게 업무효율성을 높이는 가이드라인을 제시할 수 있다.

Power spectrum analysis is a powerful noninvasive tool for quantifying autonomic nervous system activity. In this paper, We developed a measuring system for Autonomic Nervous Activity by using power spectrum analysis method to obtain the activities of autonomic nervous system. This system adopt a isolated power for patient's safety. In this system, Two output signal is obtained - R-R interval time variability and Respiration time variability. Time variability is use to find out some disease related to Autonomic Nervous System. Experimental tested range is 30 ～ 240 BPM for ECG and 15～80 BPM for Respiration.

An optical switch/modulator is designed and the light propagating characteristics is analyzed by the simplified BPM. The distinctive feature of the switch/modulator is that all the waveguide branches are designed to be single-mode. Principle of the device is based on the coupled mode theory in the Y-junction interconnecting waveguide. In spite of all the waveguides are designed to be single-mode, adjusting the interconnecting waveguide length of the device, the same characteristics as existing device up to date is obtainable. Numerical results show that the switching characteristics periodically depends on the interconnecting waveguide length with a spatial of about 150${\mu}m$ in the Ti:LiNbO3 step index waveguide. The concept of design would be utilized effectively in fabricating the monolithic high density of optical integrated circuit.

Marine equipment makers today face a multitude of challenges including the needs of an internal system for easy management of their business processes and a collaboration system to streamline communications with the parent company, increasing product complexity and heightened requirements for information technology. In this research, a BPM-ERP system called Biz $Tower^{(R)}$ was implemented based on cloud computing for especially, small and medium marine equipment makers to standardize and visualize the entire business process from order placement to release. This system also provides their parent company with visibility into the status of orders and user can easily access the system on the web at a low price through cloud computing service. Thus far, this paper demonstrates the applicability of Biz $Tower^{(R)}$ to improve management visibility, process performance, and collaboration with the parent company for small and medium marine equipment makers.

최근 기업의 경영환경은 매우 급격히 변화하고 있으며 지속적인 고객가치 향상에 대한 압력을 받고 있다. IT투자의 가장 중요한 목표는 더 이상 단순히 생산비용을 낮추는 것이 아니고 최적화된 대량 생산을 위해 디지털로 연결된 세상에서 고객들과 파트너들에게 기업의 유용성을 높이는 데 있다. 따라서 기업들은 BPM을 통해 확장된 기업의 프로세스를 자동화 하고, 통합하고 최적화하기 위해 모든 역량을 집중하고 있다. 또한 RFID 응용시스템을 통해 기술적 측면에 접근하여 비즈니스 확장을 위한 시스템 개발에 주력하고 있다. 그러나 기술적 측면, 비즈니스 프로세스적인 측면 조직적인 측면을 함께 고려하여야 성공적인 기업 역량을 이룰 수 있을 것이다. 따라서 본 논문에서는 기존의 BPM 에 RFID 시스템을 통해 비즈니스 프로세스에 대한 접근 모델을 제안하였다. 이 방법론을 통해 비즈니스 프로세스 분석에서부터 시스템 분석 및 설계에 따른 시간 비용, 품질, 및 고객의 만족 수준에 혁신적인 개선을 이끌어내는 접근 방법론을 기대할 수 있다.
