  • 본 논문에서는 기존의 LCMS에서 사용되는 평가시스템에 퍼지 추론 규칙을 이용한 적응형 퍼지평가시스템(AFES ; Adaptie Fuzzy Evaluation System)을 제안한다. AFES 는 학습자가 하나의 학습코스(learning course)에 들어가기 전에 퍼지진단평가(fuzzy diagnostic evealuation)를 통해 학습자에게 코스수준(course level)을 부여한다. 학습자는 코스수준에 따른 맞춤식 학습경로(learning path)로 학습을 종료한 후, 퍼지최종평가(fuzzy final evaluation)를 통해 최종성적(final grade)을 AFES 으로부터 부여 받는다. AFES의 가장 큰 특징은 최종성적의 점수 부여 규칙에 있는데, 만약 서로 다른 학습자가 동일한 문제 수에 대하여 같은 수의 정답을 냈더라도, AFES 는 125 가지 퍼지 추론 규칙(fuzzy reasoning rule)에 의거하여 탄력적으로 서로 다른 최종성적을 학습자에게 부여한다.

  • This paper examines the correlation between midterm and final evaluations using quantitative assessment data from an online liberal arts course titled "Software and Computational Thinking" over four semesters. The course was conducted through pre-recorded video lectures, and the same conditions were maintained throughout the four semesters. The study results showed that the course satisfaction rate in the final evaluations was lower than that in the midterm evaluations across all assessment items. This is likely because improvements based on student feedback from the midterm evaluations were not implemented within the same semester, and the rate of insincere responses increased in the final evaluations. Moreover, objective evaluation items such as "Adherence to Syllabus" and "Relevance of Lecture Content" showed a statistically significant correlation between midterm and final evaluations. However, for assessment items where subjective judgment, such as "Lecture Comprehension", is important, no significant consistency was observed between midterm and final evaluations over the four semesters. The evaluation of subjective assessment items is closely related to the perceived difficulty of the lectures by the students, and in engineering-related courses, this connection is even stronger. Therefore, in the case of liberal arts courses in engineering, where students from various majors are enrolled, it is natural that the perceived difficulty of the lectures differs among students as the course progresses, and that the change in perceived difficulty between the midterm and final evaluations also varies. As a result, it is understandable that there is a lack of consistency in subjective evaluation items between the midterm and final evaluations. These findings suggest that to enhance student satisfaction and maintain consistency in course evaluations throughout the semester in engineering liberal arts courses, it is necessary to design and operate the lectures with differentiated practical content tailored to the academic backgrounds of the students.

  • This study was conducted to develop a basic pants pattern reflecting the average body shape of Chinese women in their 20s by using a virtual fitting method. A formula for the research pattern was derived by applying the measured value based on the drafting method of existing patterns. The final pattern was presented through two actual fitting processes. The suitability of the final pattern was then verified through a functional evaluation and an appearance evaluation based on an actual fitting and a virtual fitting. As a result of the evaluations, the final pattern reflected the body shape of Chinese women in their 20s and was evaluated as a higher quality pattern compared to existing patterns. The final pattern was based on the omphalion waist circumference. Ease amounts were set to be the omphalion waist circumference + 1.0 cm, hip circumference + 2.0 cm, and the pants length was set to 94 cm.

  • This study is conducted to improve the fitness of Air Force winter service uniforms pants through the development of a pants pattern drafting method and automatic pattern drafting program for mass customization. The initial study pattern drafting method is formed through an analyses of 4 kinds of conventional pants pattern drafting methods for education and 3 kinds of conventional pants patterns of Air Force apparels. The initial study pattern drafting method is converted into the final study pattern drafting method after twice conducting a wearing test. To verify the final study pants pattern, a motion adaptability evaluation, an ease amount evaluation and an appearance evaluation are conducted. The results of the final study patterns were better than conventional winter service uniforms in the motion adaptability evaluation and the appearance evaluation. However, the results show similar values between the final study patterns and conventional winter service uniform patterns in the ease amount evaluation. An automatic pattern drafting program was developed based on the final study pattern drafting method. The program allowed the achievement of customized pants patterns through the placement of customer body sizes into the size input window. It also provided two kinds of ease amount and two kinds of waist belt level options.

  • The purpose of this study is to develop an evaluation index for evaluating the economic value of libraries. To this end, a preliminary evaluation index was derived from analyzing a total of approximately 60 domestic and foreign papers that examined the value of libraries. Based on the derived preliminary evaluation index, 11 experts were selected and the final evaluation index was developed by conducting the Delphi survey for 3 times. The final evaluation index consists of four evaluation areas, such as the economic value of the public library, economic revitalization, manpower development and job creation, and the improved investment value, seven evaluation items, and 22 evaluation indices. In the future, it will be necessary to conduct research to measure the economic value of public libraries.

  • In commercial digital-cameras, color-filter filters light according to wavelength range of color filter array (CFA) and the filtered intensities contain color information of light. Then, output data of CFA is transformed to final rendered image through demosaicing process. In image processing of digital-camera, the quality of the final rendered image is affected by optical cross talk of CFA, kind of CFA pattern etc. Basically, pattern of CFA plays important role in image quality of final image rendered by digital-camera. Therefore, an evaluation system capable of quantitatively evaluating CFA is needed. This paper proposes a novel evaluation system using existing and proposed image metrics for evaluating CFAs of digital-camera. Proposed CFA evaluation system consist of color difference in CIELAB and S-CIELAB, Structure SImilarity (SSIM), MTF50, moire starting point (MSP), and subjective preference (SP). MSP and SP are newly designed for the proposed evaluation system. Proposed evaluation system is expressed in polar coordinates to analyze the characteristics of CFA objectively and intuitively. Through simulations, we confirmed that proposed CFA evaluation system can objectively assess performance of developed CFAs.

  • Recognizing a limits on quantitative evaluation of cultural contents' and for its betterment, study aims developing a qualitative evaluation model. For this study, Reception Theory, Semiotics and Psychology were derived for epistemological dimension to contemplate culture contents' essential attribute. To be concrete, cultural contents was examined as experiential products, emotional products, rememberable products and texts. Also, codes of fun, emotion and culture were discussed as intrinsic attributes for cultural contents and how those attributes were expressed or composed in cultural contents was discussed as well. Evaluation items were extracted based on final discussion at the epistemic level, set up the final evaluation model by taking experts' advices on each items. With all those outcomes, qualitative evaluation model for cultural contents was developed. For the importance of each index in the model, priority was granted by weighting on each index. Lastly, evaluation scale was developed for each index. The culture contents' evaluation model developed in study is meaningful not only in drawing qualitative evaluation items of video(image) contents and developing the index and model for the first time, but also its possibility of wide use for other genres.
