복잡계에서의 동기화는 기본적으로 카오스 신호에서의 동기화 이론에 근거를 두고 발전하고 있으나 카오스 신호보다 복잡도가 커서 동기화하는데 어려움이 있다. 이에 본 본문은 복잡계에서 동기화 기법을 적용하기 위한 새로운 임베딩 구동 동기화 기법을 제안하고 이 동기화 기법을 적용하여 복잡계에서 동기화 결과를 알아보고자 한다.

This is a experiment about change of highlight point by HBU and HLM of auxiliary function of gradation in color scanner. The result of change - over by HBU and HLM are summerized as follows. Therefore, the determination for the effective point and the amount of HBU and HLM are decided by the Table 1 and Table 2.

A Photosensitive Crown Ether Styryl Dye derivative(CESD) was prepared for the application and the structure of it was discussed. Light excitation causes the trans-cis isomerization of CESD yielding a conformation suitable to form a coordination bond between an anion group and a metal cation located in crown ether. Intermolecular complex stabilized the cis isomer that absorbs at a shorter wavelength in the trend-cis isomerization. Application of CESD was suggested.

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.

This paper examines technical writing and teaching methods based on the perspectives of the complex learning system theory. So, the paper first discusses the constituent elements and characteristics of the complex learning system theory and continues to examine the potential of applying the complex learning system theory to new teaching methods. As a result, not only did the research expand the approach methods of providing technical writing education but also confirmed the potential of actual implementation. Such results will provide a leeway to start applying new teaching methods for technical writing education. Furthermore, the paper proposes more detailed case studies related to this topic as well as development of this research to produce textbooks and other higher level researches.

Bandpass sampling technique has an advantage that it uses lower sampling frequency than Nyquist criterion. But special care is required in choosing sampling frequency to avoid self-image overlapping in the first Nyquist region. Recently, the second-order BPS techniques which can suppress possible self-image by using an additional ADC and by employing digital signal processing have been proposed. This paper addresses a complex BPS based SDR front-end. Unlike general second-order BPS, it needs simple FIR filter to compensate delay in the second ADC. We show a method to find proper sampling frequencies to down convert RF signals selected by tunable RF filter operating in arbitrary frequency range.

Recently a demand for student-centered creative design education is rapidly growing, but well organized design curriculum and design practice complex are not established properly in most universities. In this paper, we present a scheme for design-centered engineering curriculum and a method to build a design practice complex for creative design education which it is currently attracting a lot of interest in engineering education. Based on the analysis of the conventional curriculum of electronic engineering, a new curriculum and a design practice complex that is suitable for enhancement of professional practice capability and by which an effective engineering education through introductory design, element design and advanced design steps can be performed is described.

For the effective use of satellite communication transponder, tests for the payload system such as IOT(In-Orbit Test), RPM(Routine Payload Monitoring), CSM(Communicatios System Monitoring), and REV(Remote Earth-Station Verification) have to be conducted. Those tests are used in order to verify the condition and generic design of the satellite, to provide a database for operational calculations, and to maintain the quality of communication services. As the satellite communication system gets with wider expansion with higher complexity of operation, tests for the communication system also need more complex operation that usesophisticated computer-controlled measuring system. For and C language based measurement functions, which uses GPIB protocol and SCPI commands. But SICL requires knowledge of BASIC and C language as well as GPIB and SCPL system. This paper introduces a new language called CALSTEP-Control and Access Language for the Systems of Test Equipment and Payload. This language is designed for the operator to perform the tests for the satellite communication system without any special knowledge that is mentioned above. This language has very limited number of commands which are to be used to control the payload system and test equipments to perform IOT and CSM, and those commands are very readable and easy to understand, so an operator without any knowledge of BASIC and C programming language, or SICL and SCPI command can use it.

Professional communication skills in writing and speaking with multiple and complex audiences are required to engineers in society of modern technology. In this paper, we proposed the effective assessment system for the Program Outcomes on the communication skill competence(PO7), which is one of the 12 program outcomes stipulated by ABEEK (Accreditation Board for Engineering Education of Korea). To ensure logical connectivity of the assessment system, we carefully selected the performance criteria by defining the core concept of "written communication" and "verbal communication". Based on the selected performance criteria, the whole process of creating assessment tools and rubrics was explained in detail. It can be expected that the assessment for the Program Outcomes on the communication skill competence would be more systematic by using the proposed assessment system.
