This study is on the use of mathematics program for School Mathematics Education. According to the ‘technology principle’ by NCTM and teaching-learning methods by the 7th curriculum, we developed mathematics learning activities with mathematics program. This activity is to construct designs with graphs by using mathematics program(GrafEq.). In this study, we practiced these learning activities with pre-service mathematics teachers. The mathematics educational effects of these learning activities in this study are analyzed as follows; active & spontaneous search for mathematical knowledge, the experience of problem solving, affirmative view-point of mathematics, understanding of practical use of mathematics, acquisition an interest & motivation of learning mathematics etc. When students learn graphs of function, the concept of inequality in secondary school mathematics class., mathematics teachers can make a good use of constructing designs by mathematics program(GrafEq.). This will help to practice of teaching-learning methods by the 7th curriculum.

A scheme of expert system based on iterative learning control is proposed. Iterative learning control can obtain control experience from the historical data to build the knowledge base of expert system. Considering some uncertain factors, a flexible measure is adopted in iterative learning control (ILC). Simulation proves the feasibility and effect of the air conditioning control expert system based on flexible iterative learning control (F-ILC). Finally, a feedback compensation unit is incorporated against irregular heavy disturbance.

Traditional CVP (Cost-Volume-Profit) analysis employs linear cost and revenue functions within some specified time period and range of operations. Therefore CVP analysis is assumption of constant labor productivity. The use of linear cost functions implicity assumes, among other things, that firm's labor force is either a homogenous group or a collection homogenous subgroups in a constant mix, and that total production changes in a linear fashion through appropriate increase or decrease of seemingly interchangeable labor unit. But productivity rates in many firms are known to change with additional manufacturing experience in employee skill. Learning curve is intended to subsume the effects of all these resources of productivity. This learning phenomenon is quantifiable in the form of a learning curve, or manufacturing progress function. The purpose d this study is to show how alternative assumptions regarding a firm's labor force may be utilize by integrating conventional CVP analysis with learning curve theory, Explicit consideration of the effect of learning should substantially enrich CVP analysis and improve its use as a tool for planning and control of industry.

This study aimed to analyze the relationship between the learning perception of aviation service subjects using role play on the interpersonal competence, learning satisfaction, and learning outcomes of college students majoring in aviation service. A survey was conducted targeting 217 university students majoring in aviation service who are enrolled in universities in the metropolitan area and Chungcheong area and have experience in class using role play. In addition, the hypothesis is verified using the structural equation model. Among the perceptions of role play classes experienced by university students majoring in aviation service, 'inter-dependency' was found to have a positive (+) effect on all sub-factors of interpersonal competence. And 'usefulness' confirmed the positive (+) influence relationship with 'temperament for others' and 'communication' except for 'relationship promotion' of interpersonal ability. Among sub-factor of interpersonal competence, it is confirmed that only the factors of 'temperament for others' and 'communication' had an effect on learning satisfaction. And it is proved that learning satisfaction is an important determinant of learning outcomes. Therefore, this study is expected to serve as a basis for deriving an efficient and optimal learning method for practical subjects in aviation service majors.

The new field of learning control devleops controllers that learn to improve their performance at executing a given task, based on experience performing this task. the simplest forms of learning control are based on the same concepts as integral control, but operating in the domain of the repetitions of the task. This paper studies the use of such controllers ina decentralized system, such as a robot with the controller for each link acting independently. The basic result of the paper is to show that stability of the learning controllers for all subsystems when the coupling between subsystems is turned off, assures stability of the decentralized learning in the coupled system, provided that the sample time in the digital learning controller is sufficiently short.

The purposes of the study were to investigate the participation of artists in paper circuit computing learning and to conduct an in-depth study on the formation and development of practical knowledge. To do this, we selected as research participants six artists who participated in the learning program of an art museum, and used various methods such as pre-open questionnaires, participation observation, and individual interviews to collect data. The collected data were analyzed based on community of practice theory. Results showed that the artists participated in the learning based on a desire to use new technology or find a new work production method for interacting with their audiences. In addition, the artists actively formed practical knowledge in the curriculum and tried to apply paper circuit computing to their works. To continuously develop the research, participants formed a study group or set up a practical goal through planned exhibitions. The results of this study can provide implications for practical approaches to, and utilization of, paper circuit computing.

Purpose : The aim of this article is to describe the nurses' experiential learning mechanism on patient safety. Methods : To analyze nurses' learning experiences on patient safety cases, a focus-group interview method was used. The Kolb's experiential learning model was used as a reference model. Findings : Without deep reflective reasoning about specific experiences, there is no creative or innovative solutions to experiment actively. Nurses are likely to be reluctant learners when there is no systemic support from formal departments which is in charge of patient safety and quality of care. Conclusion : In order to build patient safety culture in hospital, there should be efforts to make nurses as active learners on patient safety as well as to build learning environments in medical units.

Purpose: The purpose of this study was to implement and evaluate the learning contracts based self-directed learning in a final clinical placement for senior nursing students. Methods: This study was a case study and 82 senior nursing students at a university participated in a learning contract based practice placement. Data were collected from written learning contracts and questionnaires after a clinical practice. Results: The students' learning needs were knowledge, clinical skills, and attitudes frequently encountered in a ward in which clinical skills were most common. The students' formulated learning contracts were varied but most of them were basic and simple. A self-directed clinical course was beneficial and a satisfactory experience to senior students. There was an increase in the students' motivation in learning, confidence in own capability, and satisfaction with the use of the learning contract. Conclusion: Self-directed clinical practicum would result in a degree of attitude change in the students. This study suggests that learning contract based self-directed clinical practice is effective to improve learning satisfaction, confidence in own capability, and competency.
