입시위주의 암기식 교육풍토 개선을 위한 하나의 방편으로 1999년부터 전국 초 중등학교에서 수행평가가 실시되고 있다. 수행평가는 학생에게 학습과제를 제시하여 수행과정과 결과를 관찰하고 판단하는 평가 방식으로, 단편적인 영역에 대해 일회적으로 평가하지 않고 학생 개개인의 변화 발달과정을 전체적으로 파악하기 위해 종합적이면서도 지속적으로 평가하여야 한다. 그러나 현 교육여건 하에서 과도한 수의 학생을 관찰하여 결과를 처리해야하는 교사와 체계적이지 않은 수행평가 운영방식으로 수시로 평가를 받아야 하는 학생에게 수행평가는 본연의 기능과 의미를 상실해가고 있다. 이에 교사의 수행평가 업무를 관리하여 업무량을 경감시키고, 학생의 수행평가 일정과 성적을 관리하여 성장과 발달에 도움을 줄 수 있는 수행평가 관리 시스템을 구현하였다.

본 연구의 목적은 최근 운전자 행동에 대한 연구 방법으로 매우 중요하게 대두되고 있는 운전 시뮬레이션 방법을 이용하여 운전자들이 보이는 기본적인 운전 수행 능력 및 이러한 운전 수행 능력과 관련이 가장 깊은 것으로 기존의 연구들이 밝혀왔던 기본적인 지각적/인지적/운동적 수행 능력을 측정하여 운전자 수행을 평가하는 것을 목적으로 한다. 특히 운전자의 운전 수행 및 운전과 관련된 기본적인 정신/운동 수행 능력은 정보 처리적 관점에서 측정되고 분석되었으며, 이를 통해 운전자들이 보이는 기본적인 정보처리 능력의 패턴에 대한 전반적 이해를 시도하였다. 본 연구에서는 기본적인 운전 수행 능력을 평가하는데 사용되는 차량의 속도 유지와 차선 유지에 대한 측정치와 더불어 운전과 관련한 인간 수행 중에서 단순 반응 능력, 선택 반응 능력, 속도 추정 능력, 청각적 주의나 시각적 주의의 분산 능력 등이 운전 시뮬레이션을 통하여 운전 중에 실시간으로 측정되었다. 본 연구에서 수집된 자료는 운전자들의 실제 운전 수행 및 이와 관련된 정보 처리 활동에 대한 표준화된 준거를 제시하는데 기초적 자료로 사용될 수 있으리라 생각된다.

Performance assessment has Problems about possibilities of assessment fault by appraisal, fairness, reliability, and validity of grading, ambiguity of grading standard, difficulty about objectivity security etc. This study proposes fuzzy Performance assessment system to solve problem of the conventional performance assessment. This Paper presented an objective and reliable performance assessment method through fuzzy reasoning, design fuzzy membership function and define fuzzy rule analyzing factor that influence in each sacred ground of performance assessment to account principle subject. Also, performance assessment item divides by formation estimation and subject estimation and designed membership function in proposed performance assessment method. Performance assessment result that is worked through fuzzy Performance assessment system can pare down burden about appraisal's fault and provide fair and reliable assessment result through grading that have correct standard and consistency to students.

In education, evaluation is an important element because instructor can judge the growth and development of students, it has been to bring about quality improvement in education. Performance assessment has emerged to overcome traditional evaluation such as paper test, multiple choice test. Performance assessment is an approach to measuring a student's status based on the way the student completes a specified task. Information literacy instruction is aimed at cultivating information literacy. Performance assessment suitable for measurement to status of Information literacy. In order to performance assessment, task should have the first. However, instructor is difficult to develop a good performance task to meet the assessment needs. Therefore, this research aims at suggesting the developmental tool of performance task applicable to Information literacy instruction. The proposed tool is a template type, consists of 4 steps, educational goals and learning objectives, knowledge and capabilities, task types, measurement and scoring criteria.

The purpose of this paper is to test construct validity of contextual performance of social worker. The participants in this study included 170 social worker in community welfare center nationwide. A narrative data of social work practice experience and MTMM(multitriat-multimethod) data on job performance were collected. I classified meaningful contextual behavior cases by qualitative methods, and examined discriminant validity of contextual and task performance by CFA model. Data analysis showed that social workers' contextual performance has discriminant validity and sub constructs of this concept have internal consistency. However, some construct are not completely independent.

This study is descriptive research to investigate frequency of performance, self-confidence and performance assessment scores of core nursing skills by 227 nursing students. As the result of this study, they who experienced more than 10times in clinical practice was V/S and they never experienced items such as transfusion, enema and T-tube care. For pre self-confidence, they had the highest V/S and the lowest transfusion. For post self-confidence, they had the lowest IM. As a result of the evaluation, oxygen therapy with nasal cannula was measured highest, and IM was measured lowest. Frequency of performance had positive correlations with self-confidence(r=0.414, p<.001) and performance assessment scores(r=0.322, p=.007). Self-confidence with performance assessment scores had positive correlation(r=0.281, p=.003). Study results suggested that clinical practice is carried out, non-invasive, simple measurements, and they had low self-confidence of the items with low frequency of performance, so convergency training methods to complement this point are needed.

Objective : The purpose of this study was to investigate the effect of telerehabilitation on executive function, activities of daily living, instrumental activities of daily living, and occupational performance in stroke patients. Methods : The participants of this study were 30 outpatients with stroke residing in community. Both groups underwent the intervention 3 times a week for a total of 18 sessions. For the experimental group telerehabilitation was administered at home to only fifteen participants in the experimental group schedule, and it was supervised by the caregiver. Fifteen people in the control group underwent only the traditional occupational therapy. Executive function and instrumental activities of daily living were evaluated using the Korean version of the Executive Function Performance Test (EFPT-K). The basic daily activities of living were assessed using the Modified Barthel Index (MBI). The Canadian Occupational Performance Measure (COPM) was used to evaluate the client-centered occupational performance. Results : After the intervention, the experimental and control groups showed improvements in executive function, instrumental activities of daily living and occupational performance. Occupational performance improved more significantly in the experimental group than in the control group. Conclusion : Telerehabilitation and occupational therapy positively affect executive function, instrumental activities of daily living and occupational performance of patients with stroke. We suggest that telerehabilitation combined with occupational therapy is more effective in improving the occupational performance of stroke patients.

Because wireless links are subject to disturbances and failures, it is important to support disconnected operations in mobile computing. Many schemes have been proposed to support the efficient disconnected operations. In this paper, we analyze and measure the computation time including disconnected operations to evaluate the performance of mobile computing on error prone wireless links. Mobile computation consists of three states: data hoarding, disconnected operation, and block states. We estimate the computation time using various parameters; error rate and recovery rate of wireless link, hoarding overhead, logging overhead, and reintegration overhead, etc. We can choose efficient strategies for disconnected operations and predict the performance using the results of this analysis.

기존의 강성 실시간 시스템은 실시간 수행만 고려되어 있어. 실시간 시스템의 성능과 효율적인 시스템 활용과는 거리가 멀다. 따라서 효율적인 시스템 활용을 통하여 보다 많은 일을 수행할 수 있게 하는 연성 실시간 시스템을 사용하게 된다. 여기서는 보상값이라는 것을 사용하여 그것의 총합을 성능평가의 기준으로 사용하며, 보상값의 합을 최대로 할 수 있는 수행시간을 찾아 스케줄링에 사용하게끔 한다. 모의 실험을 통하여 알아낸 수행시간에 따른 보상값의 변화에 대한 경향을 이용하여 최대 보상값을 얻을 수 있는 수행시간을 찾고, 실험을 통하여 얻은 결과와 비교하였다.
