Learning Diagnosis & Prescription Service(LDPS) in Cyber Home Learning System is a educational service which provides customized learning contents based on student's academic level and individualized counseling and comments after diagnosing learner's study habits beyond the past e-Learning systems which offer the same contents to different students. For a national point of view, it is a crucial project in public education to achieve the goals of the next-generation e-Learning service by making a lot efforts both in time and money. However, those efforts has been made, not in terms of providing a better quality of service and a better user experience in a effective and enjoyable way, but in terms of developing the technology-driven system. Therefore, in this study, two types of usability evaluations has been conducted in order to enhance a user experience on the LDPS. One is the expert reviews by utilizing the usability evaluation tools (heuristics) which was focused on educational contexts developed by Suh Young-suhk(2007). The other is the user testing with students who have done think-aloud during the evaluation, remembering their retrospective experience with LDPS, and the interview with teachers & service operators were conducted. As the implications on the research, this is an effort to provide an user-friendly educational system for the students nationwide.

The purpose of this study was to investigate the effect of a peer evaluation method on the core fundamental nursing skills competency, learning attitude, critical thinking and self-leadership of graduating nursing students. A survey using a questionnaire was administered to 326 nursing students. The data was analyzed using SAS(ver. 9.8) and AMOS(ver.20.0) The results of peer evaluation showed that the fundamental nursing skills competency was 3.77(${\pm}.62$), the learning attitude was 3.17(${\pm}.47$), critical thinking was 3.44(${\pm}.41$) and self-leadership was 3.60(${\pm}.49$). Core fundamental nursing skills competency showed statistical differences based on gender, major satisfaction, practice satisfaction, pre-learning and satisfaction with the peer evaluation. Core fundamental nursing skills competency was positively correlated with learning attitude(r=.295, p<.001), critical thinking was positively correlated with core fundamental nursing skills competency(r=.384, p<.001) and learning attitude(r=.623, p<.001), and finally, self-leadership was positively correlated with core fundamental nursing skills competency(r=.353, p<.001), learning attitude(r=.529, p<.001) and critical thinking(r=.690, p<.001). The factors affecting fundamental nursing skills competency were critical thinking and self-leadership. Core fundamental practical education programs to improve learning attitude, critical thinking and self-leadership need to be developed to increase core fundamental nursing skills.

In this paper, we construct an automatic evaluation system of psychological feeling for corporate identity (CI) symbol mark based on a fuzzy neural network technique. The system is modelled by trainable fuzzy inference rules with several input variables (qualitative and quantitative design components of CI symbol mark) and a single output variable (consumer's feeling). The back propagation learning algorithm, which is a conventional learning method of multilayer feedforward neural networks, is used for parameter identification of the fuzzy inference system. The learning ability to train data and the generalization ability to test data are evaluated for the proposed evaluation system by computer simulations.

A new state evaluation approach for structural safety is presented in this study. To reduce the subjectivity of the view and judgement of each expert founded on a limited body of knowledge in cognitive and inferential process of safety assessment, we introduced inductive learning method in AI. Inductive learning derives generalization from experiences. Decision tree induction algorithm analyzes the domain knowledge, produce rules via decision trees and then allow us to determine the classification of an object from case examples. The training set of state evaluation is constructed according to the selected attributes from working reports of RC bridge girders.

Education paradigm is moved from traditional face-to-face method to cyber education environment. Therefore, we extracted the components of cyber education system and their detail functions through analysis on the workflow of education and learning standard technology. In addition, we think that template system will make a big role in order to deploy the cyber education system. Therefore, we designed the template system for cyber education. In this paper, we particularly describe both evaluation funrtion on course learning records and statistics function ell evaluation records.

This study proposes an automated assembly performance evaluation method for prefabricated steel structures (PSSs) using machine learning methods. Assembly component images were segmented using a modified version of the receptive field pyramid. By factorizing channel modulation and the receptive field exploration layers of the convolution pyramid, highly accurate segmentation results were obtained. After completing segmentation, the positions of the bolt holes were calculated using various image processing techniques, such as fuzzy-based edge detection, Hough's line detection, and image perspective transformation. By calculating the distance ratio between bolt holes, the assembly performance of the PSS was estimated using the k-nearest neighbors (kNN) algorithm. The effectiveness of the proposed framework was validated using a 3D PSS printing model and a field test. The results indicated that this approach could recognize assembly components with an intersection over union (IoU) of 95% and evaluate assembly performance with an error of less than 5%.

This study is a theoretical exploration of project-based service-learning and its application in designing pre-dental curricula. As a response to the limitation of community service courses, service-learning has been implemented as pedagogy in higher education practices. Service-learning connects service and learning by engaging students in activities that address community needs with intentionally designed learning opportunities while adding value to and transforming both service and learning. Project-based service-learning is an extended and more active version of service-learning. Whereas service activities are arranged by instructors in the original service-learning, project-based service-learning provides students with opportunities for exploring problems and root causes on site and then devising and implementing solutions of their own using their talents and creativity. This study proposes a theoretical approach to project-based service-learning and suggests six design components, namely, related curriculum, reflection, reciprocity, service and community engagement, evaluation and recognition, and creative problem solving. Based on the components, 20 design strategies are formulated. The exploration is aimed to provide design guides for professionals attempting to implement project-based service-learning in higher education.

The purpose of this study was to identify learning topics linked to Sustainable Development Goals(SDGs) in the dietary life unit of middle school technology and home economics textbooks and to develop teaching-learning plans and learning materials to verify the feasibility and field suitability. This study was carried out through analysis, design, development, and evaluation stages, and the results are as follows. First, in the analysis stage, the dietary life contents of the five home economics textbooks written based on the 2015 revised curriculum were analyzed, and dietary life-related goals were extracted from the 169 SDG targets to reorganize the learning topics linked to the contents of the textbooks. Second, in the design stage, the overall goal of the entire class was set and each session was designed by selecting the learning goals, learning topics, and learning contents, reflecting the SDGs related to the session to be developed. Based on the analyses of textbooks and the SDGs related to dietary life, the themes of 'desirable eating habits of adolescents', 'food production', 'food distribution', and 'food consumption and disposal' were extracted. Third, in the development stage, a total of 11 teaching-learning plans and student worksheets were developed, and an evaluation sheet was developed for expert verification. Fourth, in the evaluation stage, the feasibility and field suitability of the teaching-learning plans were verified by 5 home economics teachers. Learning goals, learning contents, connectivity to related SDGs, and feasibility of teaching-learning plan were evaluated, and based on the assessment results, teaching-learning plans were revised.
