Since software reuse and agile development methods are seen as ways to shorten development time and accept frequent requirement changes, respectively, there has been growing interest and research on integrating these approaches. But despite the increasing number of software companies which have successfully adopted agile development methods, there has been little research on reuse in agile methods to further improve productivity. In this paper, we identify a new type of reuse asset and propose a task factoring technique by taking advantage of iteration characteristics to support reuse in agile software development methods. In addition, we can apply the proposed technique and show prototyping of task reuse in a video rental application.

SolarPACES(Solar Power and Chemical Energy systems) is an international organization under the REWP(Renewable Energy Working Party)in the IEA(International Energy Agency) and focuses on the technology development and market expansion of CSP(Concentrating Solar Power). Seventeen countries including Rep. of Korea participate in the ExCo(Executive Committee) of SolarPACES. The ExCo meeting helds two times in a year and the second ExCo meeting opens in company with the five Task meetings. Rep. of Korea takes part in the Task-1officially. The 81th ExCo and Task meetings were held during September 18 and 19 in Spain with SolarPACES conference which also continued in succession to September 23 in this year. This paper introduces the activities which have been under progressed in the Task-1 and Task-3based on this time attendance of the meeting. In accordance with the expansion of CSP market and technology development, the needs for the standardization and project status underway in the world are increasing. Therefore, build an international project database and standard of the CSP technology are the main activities in the Task-1 and the standardization is also connected with the Task-3. In addition, to increase the reliability of the new technology of CSP and to reduce the concern of investors, the Task-1 is making guidelines for CSP performance prediction which can provide medium quality calculated performance data of PTC(Parabolic Trough Concentrator) type technology widely used and occupies over 90% CSP market.

The purpose of this study is to confirm whether the task and system development process makes a significant influence on the system performance. The task is defined as a interdependency and system development process is defined as analysis, user participation and executive support. Field research was employed to empirically investigate the relationship among the variables. The finding of the study can be summarized as follows. The strict analysis under the task of high interdependency has a significant effect on the system performance. And high executive support is needed for the system performance under any level of interdependency.

The purpose of this study is to develop an examination system for an e-learning quality manager's certificate which is composed of subjects, criteria, method of examination. The task model of e-learning quality manager was modify and task/knowledge/skill matrix was developed to design the examination system through conferences of DACUM committee and an advisory committee. And a survey was carry out to analyze validity of contents of the examination system. The major findings were as the follow: First, occupational specification, job specification, task specification and task/knowledge/skill matrix were developed. Second, examination subjects were developed based on task/knowledge/skill matrix, which were "Basis of e-Learning and plan of service", "Expulsion and management of e-learning infrastructure", "Development of e-learning contents", "Operation and evaluation of e-learning service". Third, the criteria and methods of examination for an e-learning quality manager's certificate were developed, which is composed of test type, the sum of test items, test time and acceptable standards.

Performance assessment is one of the authentic assessment method that are consistent with new curriculum goal, concentrated on the process rather than the results of problem solving. But the key to good assessment is matching the assessment task to intended objectives. Based on the review of literatures, the current performance assessment task was critically analysed. As a result, this study developed appropriate model and criteria of performance assessment task to elementary mathematics.

This paper presents an algorithmic approach used in the development of a task-level off-line programming system for the efficient applicaiton of robot. In the method, robot tasks are graphically described with manipulation functions. By applying robot language these graphic robot tasks are converted into commands for the robot. A programming example demonstrates the potentiality of task-oriented robot programming.

With the progress in process automation, it becomes necessary that a robot should have various sophisticated capabilities. A robot programming language is a tool that can give a robot such capabilities without any change in robot architecture. Especially a task level automatic programming system enables a robot able to perform a job intelligently. Therefore anyone who is not an expert on welding or robot programming can easily use it. In this research, basic automatic welding program is combined with workspace information, which makes users do an arc welding job automatically.

This study analyzed the difficulties and mathematical modeling knowledge improvement that an elementary school teacher experienced in modifying a mathematics textbook task to a mathematical modeling task. To this end, an elementary school teacher with 10 years of experience participated in teacher-researcher community's repeated discussions and modified the average task in the data and pattern domain of the 5th grade. The results are as followings. First, in the process of task modification, the teacher had difficulties in reflecting reality, setting the appropriate cognitive level of mathematical modeling tasks, and presenting detailed tasks according to the mathematical modeling process. Second, through repeated task modifications, the teacher was able to develop realistic tasks considering the mathematical content knowledge and students' cognitive level, set the cognitive level of the task by adjusting the complexity and openness of the task, and present detailed tasks through thought experiments on students' task-solving process, which shows that teachers' mathematical modeling knowledge, including the concept of mathematical modeling and the characteristics of the mathematical modeling task, has improved. The findings of this study suggest that, in terms of the mathematical modeling teacher education, it is necessary to provide teachers with opportunities to improve their mathematical modeling task development competency through textbook task modification rather than direct provision of mathematical modeling tasks, experience mathematical modeling theory and practice together, and participate in teacher-researcher communities.

The Gross Motor Function Measure (GMFM) is an internationally widely used outcome measure. The aim of this study was to evaluate the structural properties of the Korean version of GMFM using the Rasch Model, with regard to scoring within rehabilitation centers in Korea. GMFM data for 206 children with cerebral palsy were collected from 11 outpatient rehabilitation facilities by 29 pediatric therapists. The Winsteps software was used to refine the rating scale. This study suggests that the scoring categories of the Korean version of the GMFM should be collapsed from 0 (subject does not initiate task), 1 (subject initiates task), 2 (subject partially completes task), 3 (subject completes task) to 0 (subject does not initiate task), 1 (subject initiates or partially completes task), 2 (subject completes task) for better accuracy in estimating the gross motor function of children with cerebral palsy.
