The modem multimedia applications which are video Processor, video conference or video phone and so forth require real time processing. Because of a large amount of image data, those require high compression performance. In this paper, the proposed image processing encoder was designed by using wavelet transform encoding. The proposed filter block can process image data on tile high speed because of composing individual function blocks by parallel and compute both highpass and lowpass coefficient in the same clock cycle. When image data is decomposed into multiresolution, the proposed scheme needs external memory and controller to save intermediate results and it can operate within 33㎒.

Generating a project network of a specific construction project is very time consuming and difficult task in the field. To effectiviely automate and support the planning process, we design a case-based project planning expert system inspired by the fact a human expert project planner uses previous cases for planning a new project. A construction project case consist of its specific characteristics and the corresponding project network (i.e. project plan). Using frame based representation. we represent the project features affecting the progress network and the entities composing the project plan such as the buildings, construction methods, WBS (work breakdown structure), activities, and resources. The project planning process runs through most similar case retrieval, case adaptation, and user requirement satisfaction. We represent the construction domain knowledge for each procedure using constraints and rules. We develop the methodology for constraint-based case adaption. Case adaptation process mainly consist of activity generation/deletion and predecence constraint satisfaction, for which we develop the dynamic constraint generation method and connect user-level requirement representation the system-level network modification knowledge. The methodology is being applied to the prototype for apartment construction project planning.

XPDL is a XML-based language for process definition exchange that is proposed by WfMC. This paper propose a model which model XPDL document structure (Schema) using UML in order to define and to exchange workflow process, and make business flow understanding ease for inter-business cooperation. So, we define mapping rules in which map XPDL documents into UML class diagram and UML activity diagram. By these mapping rules, elements composing XPDL process meta-model are mapped into UML class diagram, and process activities are mapped into UML activity diagram. Also, we apply proposed mapping technique to model a workflow of (')Credit card state check system.(')

This review article provides the trend of current nursing curriculum of todays in Korea and its perspectives. This article reviewed 5 aspects of the current nursing curriculum for the undergraduate program, those are the (1)educational philosophy and believes (2)the nursing concepts revealed in the current nursing curriculum (3)the educational goals and objectives (4)the framework of nursing curriculum (5)the syllabus and credit hours. The common nursing concepts in the current nursing curriculum are Nursing, Human being, Environment/society, Health, Nursing science. The examplary vertical concepts composing of the current nursing curriculum are nursing process, life styles and the horizontal concepts are client, health promotion /recovery /maintenance, leadership, and research. The common subjects composing of the nursing syllabus are the introductory subjects(nursing history, nursing professionalism, foundamental nursing), and the supportive subjects (communication, human relationship, human growth and development, health education, etc) and nursing research, the intrductory basic sciences (anatomy, physiology etc.), and the major nursing subjects (adult nursing, child nursing, maternity nursing, psychiatric nursng, community nursing, nursing administration.) In order to have more advanced nursing education, the suggestions were provided as follows : (1) It is necessary to have revision and evaluation of the process and the structure of the current nursing curriculum periodically. (2) The concept of health promotion for all human being should be integrated into the nursing curriculum. (3) The nursing education program should be unified into baccalauliate level to get one type of nurse-registration system. (4) The nursing courses will need to provide the necessary contemporary Informations to allow the nurses to fuction efficiently in this rapidly changing era. (5) The use of new technology in nursing education is necessary to expand nursing education more.

This study explored the ESL college learners' perceptions on integrating reading and writing in the context of the reading-to-write composition classroom. Using the panel survey (N=60) that repeatedly measured the same set of individuals at three different times during a semester, this study examined whether students' perceptions on reading-writing integrations were reshaped over the course of classroom practices. The survey instrument was developed to assess the perception scores from less integrative continua to more integrative continua on a 5-point Likert scale. A two-factor ANOVA with repeated measures was performed to evaluate mean differences across the perception groups and over the three treatment times. The results do not demonstrate a significant treatment effect, suggesting that L2 learners' integrative perceptions were stable over the course of the semester. The dynamics in the perception changes differed widely across the perception groups. This result provides insights into understanding students' reading-writing practices and thus into instructional practices applicable to the classrooms. The present study argues for 12 learners' perceptions on integrating reading and writing as a key construct to understand their literacy practices involved in the composing process.

The assemblability is determined by the structure of product and the relationship between composing parts and machining parts. In this paper, the bolt was divided into bolt-head, -shaft, -thread and -end. For higher assemblability in bolting process, it was analyzed the geometric and technological characteristics of bolts were analysed regarding pre- and in-assembly process. And this paper presents the knowledge-based expert system to assist for designer in the processor of designing bolt for easier assembly. The developed expert system for supporting bolt design assemblability which is named as BDFA SYSTEM consists of two system such as "BOLT DESIGN SYSTEM" which provide feasible assembly bolt design to designer and "EVALUATION SYSTEM" which provide assembly evaluation to alternative of bolt design.

Laser thin film process with a Q-switch pulsed YAG laser was performed for micro machining. In this research, we performed basic Cr thin film on glass substrates removal machining experiments. Form experiments, it happens not only evaporration of thin film but also spatter and cohesion of melting substance in working region, when machining a Cr thin film by Q-switch YAG laser beam irradiation. Critical energy of surface irradiation type by irradiation direction of laser in a face composing thin film on the glass is higher than that of back irradiation type, but the latter is favorable because of spatter appearance. In case of image formation position when laser beam is irradiated, the defocus is permitted to a certain extent within forcus depth. Ifexceeds focus depth, formation of pattern is vanishing step by step.
