자가 적응 시스템은 사람의 직접적인 개입 없이 자율 제어를 통한 자가 최적화 (self-optimization), 자가 치유 (self-healing) 등의 능력이 요구되고, 이러한 시스템은 시스템이 조달된 환경과 시스템 내부 상황을 고려한 적절한 적응 정책과 목표 평가를 통해 시스템의 신뢰성을 보장할 수 있어야 한다. 목표 기반의 자가 제어 시스템은 목표 만족도에 따라 시스템을 자율 제어하기 때문에 목표 기반 자가 적응 시스템에서의 목표 만족도(goal satisfaction) 평가는 매우 중요하지만 기존의 연구들의 목표 만족도 평가 방법에서는 환경 변화가 반영되지 않는다는 한계가 있다. 본 논문에서는 목표 모델에서의 상위 목표에 대한 하위 목표들의 기여도에 따라 가중치를 부여하고 시스템의 외부 환경 변화에 따라 가중치를 동적으로 변경하는 방법을 제안한다. 이를 통해 기존의 목표 평가 방법보다 사용자의 요구가 잘 반영되고 신뢰성 높은 평가가 가능하다.

The purpose of this paper is to evaluate usability quality through investigating the factors of usability for internet shopping mall websites. For this study, previous studies were investigated and experts' discussions were held. In result, six characters of usability were chosen such as content satisfaction. customer attraction satisfaction, price information satisfaction, public security satisfaction, user interface satisfaction. and process of transaction satisfaction that affect usability of shopping mall websites and the evaluation models of 72 detailed measure factors were established. Since these 72 sub-factors inc)ode the key words of HTML, XML, JSP, and ASP from the target websites. 33 measurable sub-factors in the information were measured through usability evaluation experiment. In addition, a questionnaire about usability measure factors was executed after preferable websites and not preferable websites are selected. After that, we verified the reasonability of usability measure model factors comparing the results of the evaluation experiment with the result of the questionnaire. The time it takes to measure the usability of shopping mall websites can be reduced by using this measurement supporting tool. Also, this tool may be used to estimate the usability during the development of a shopping mall website.

The purpose of this study is to improve the validity of the evaluation by adding the factor of academic achievement to the subject of evaluation, and to improve the reliability of the evaluation by verifying the legitimacy of control of in-class attitude and developing the correction index of satisfaction of teaching. The results of the study are as follows. Firstly, it was confirmed that the students' in-class attitude had a significant effect on satisfaction of teaching. The more positive the in-class attitude, the higher the satisfaction of teaching, and vice versa. Secondly, it was confirmed that the students' in-class attitude had a significant effect on academic achievement. The more positive the in-class attitude, the higher the academic achievement, and vice versa. Thirdly, it was confirmed that satisfaction of teaching did not have a significant effect on academic achievement. High satisfaction of teaching does not mean that the quality of the teaching is high, and vice versa. Fourthly, the correction index of satisfaction of teaching was developed to correct the results of satisfaction of teaching that may be distorted due to the students' negative in-class attitude. In conclusion, academic achievement should be added as the subject of evaluation in addition to the satisfaction of teaching to improve the validity of evaluation and the correction index of satisfaction of teaching should be applied to improve the reliability of evaluation.
