Scale Invariant Feature Transform (SIFT) is an effective algorithm in object recognition, panorama stitching, and image matching, however, due to its complexity, real time processing is difficult to achieve with software approaches. This paper proposes using a reconfigurable hardware processor with integer half kernel. The integer half kernel Gaussian reduces the Gaussian pyramid complexity in about half [] and the reconfigurable processor carries out a parallel implementation of a full search Fast SIFT algorithm. We use a low memory, fine grain single instruction stream multiple data stream (SIMD) pixel processor that is currently being developed. This implementation fully exposes the available parallelism of the SIFT algorithm process and exploits the processing and I/O capabilities of the processor which results in a system that can perform real time image and video compression. We apply this novel implementation to images and measure the effectiveness. Experimental simulation results indicate that the proposed implementation is capable of real time applications.

One of the most important service industries that emerged in the last decade is "Higher Education". The most of the higher education institutes involve in marketing efforts to build up a good image, to improve the level of satisfaction of students and the stakeholders, to gain competitive advantage with respect to competitors and as well as to increase their market share. Within this intense competition universities should identify and meet the expectations of students to attract more and to retain the existing students. This study is to gain more insights into the dimensions of satisfaction of the university students and factors that affecting their judgments. SSI educational experience questionnaire is used to identify the importance and performance perceptions of students' in Eastern Mediterranean University among different dimensions and also study find out the difference between importance and performance scores of eleven educational experience dimensions. Results show that "Academic Advising", "Instruction Effectiveness", "Recruitment and Financial Aid" and "Student Centeredness" was very important to students. Study also provides managerial implications as well.

In order to improve and promote immersive learning experiences for English as a Second Language (ESL) students, the deployment of a YOLOv5 model for object identification in videos is proposed. The procedure includes collecting annotated datasets, preparing the data, and then fine-tuning a model using the YOLOv5 framework. The study's major objective is to integrate a well-trained model into ESL instruction in order to analyze the effectiveness of AI application in the field.

The aim of this study is to provide the values and descriptive implications of the Design Thinking (DT) method into the context of educational problems of practice in an undergraduate course. To achieve the research objective, both quantitative and qualitative studies were conducted. For the qualitative study, the student's productions and reflections on the experience of the application of the DT into educational problems were analyzed. For the quantitative research, one-group pre and post-test were designed to validate the effectiveness of the DT method into educational contexts in terms of creativity level to measure the student's Creativity Potential and Practiced Creativity, Academic Self-Efficacy Scale, and Problem-Solving Inventory. This study validated that the DT method had a statistically significant influence on those three competencies and also illustrated the detailed process from a qualitative viewpoint. The results and implications reflect the potential of the DT approach with the educational problem of practice, especially, in the ill-structured problem-solving contexts for student-centered instructional setting.

As the educational paradigm has shifted from the traditional knowledge oriented instruction learning to the knowledge product oriented instructional learning, the development of student's creativity becomes one of the most important educational goals, because the ability that can produce the knowledge creatively is required in the digital information knowledge based society. The purpose of this study is to make a basic direction and strategy for the instructional design to develop an on and off line blended instructional design which will help a learning community to be a more collaborative and creative learning community. This research has investigated the concept and the characteristics of collaborative creativity and creative problem solving as the theoretical basis of the design. After that, on the basis of the theories connected with the collaborative creativity theory, the direction and the strategies for the development of collaborative creativity was designed. The design was applied into the real learning community and finally proved the effectiveness of the learning model for the development of the collaborative creativity by the quantitative evaluation.

The study described in this paper examined the effectiveness of a multimedia case-based learning environment to teach technology integration to Korean pre-service teachers. The structure and philosophy behind the use of embedded video in an online, multimedia system and the data collected from 103 pre-service teachers are presented and discussed. The overall finding shows that there was no significant difference from pre- to posttest among the lecture, the case-based, and the mixed environment groups. However, low prior knowledge students improved more when they learned about technology integration with the mixed method than with the case-based method alone. Discussion about this result and its educational implications conclude the paper.

SW 역량은 미래 사회에서 필요로 하는 핵심 역량으로, 컴퓨팅 사고력을 기반으로 하고 있다. 하지만 교육 현장에 컴퓨팅 사고력의 도입은 교사와 학생의 인식과 적절한 교육 프로그램의 부족으로 도입이 어려운 실정이다. 이에, 본 연구에서는 현장에 친숙한 융합인재교육을 이용해서 개발된 컴퓨팅 사고력 기반 융합인재교육의 현장 적용을 통해 현장 적용 가능성을 제시하고, 그 효과성을 분석하였다. 연구 대상은 49명으로 실험집단 23명, 통제집단 26명으로 선정하였으며, 실험집단에 컴퓨팅 사고력 기반 융합인재교육 프로그램을 실시한 후 사전-사후 융합적 사고력 검사, 컴퓨팅 사고력 검사를 통해 프로그램 효과성 분석을 시행하였다. 연구 결과, 실험집단의 경우 융합적 사고력의 하위 요인인 과학선호도와 자기 주도적 학습능력이 유의하게 향상되었다. 또한, 컴퓨팅 사고력 점수도 실험집단에서 유의한 향상을 보여 컴퓨팅 사고력 기반 융합인재교육(CT-STEAM) 프로그램의 효과를 확인할 수 있었다. 향후, 다양한 컴퓨팅 툴을 활용한 융합인재교육 프로그램의 개발을 기대해 본다.

본 연구는 초등학교 학생들이 학습하는 온라인 영어 학습 프로그램 콘텐츠의 효과성을 탐색하였다. 온라인 영어 학습 콘텐츠 연구를 위해 경기도교육청에 의해 학교로 사용권장된 프로그램을 사용하였다. 연구대상은 경기도 K 시 소재 P 초등학교 107명의 학생들로 약 1년간의 학습 후에 온라인 학습 콘텐츠 효과성에 관한 설문에 응답하였다. 학생들의 응답은 Spearman 상관분석방법으로 재학학년, 온라인 학습시간 및 진단평가 성적과 온라인 영어 학습 프로그램 콘텐츠 간의 연관성을 분석하였다. 분석한 결과, 학년이 높고 영어 학업수준이 높은 학생일수록 문제해결형, 과제수행형과 WBI(웹기반)형의 콘텐츠는 효과적이지 않다고 생각하는 것으로 드러났다. 반면에, 온라인 학습시간이 긴 저학년학생일수록 개인 지도형, 스토리활용형과 애니메이션유형의 온라인 학습 콘텐츠가 효과적이라고 답했다. 따라서 본 연구는 온라인 영어 학습 콘텐츠의 개발에 있어서, 학생의 학년과 학습시간, 학업수준 등과 같은 학생의 특성을 고려할 필요가 있음을 제언하는 바이다.

The researcher has studied the types of accidents and injuries that most often occur to infants, toddlers and preschool children. Using this knowledge, a first aid program was developed for mothers. This researcher used a Quasi experimental study which consisted of a nonequivalent control group pretest - posttest design for injury first-aid knowle. The experimental group consisted of 32 mothers, and the control group consisted of 29. The education program consisted of the types of injury, the structure and function of skin, the methods of obsevation, first-aid awareness, and the standard of professional support in case of contusion, abrasion, laceration, fracture and burn. The education program was developed and based on 'the systemetic design of instruction' by Dick & Carey(1996) and utilized multimedia text book, pictures, examples, practice and discussions to increase understanding and effectiveness of learning. The data for this study was collected from September to early November, 2001. There were two fomative evauations, pretest and posttest with an intervention of education program. The analysis of the collected data was analyzed by descriptive analysis, ANOVA, t-test and paired t-test using the SPSS 10.0 program. The results as follows; 1. The experimental group, who was given an education program before the test, got higher marks on the injury first-aid knowledge than the control group. There was a significant difference in knowledge between experimental group and control group(t=6.578, p=.000). 2. The experimental group got higher marks on the action evaluation than the control group. There were significant differences in the certainity of action (t=8.546, p=.000) and the accuracy of action (t=7.654, p=.000) between experimental group and control group. This study examined how a first aid education program increased effectiveness in the knowledge and action of injury first-aid.
