  • Facial expression recognition plays a significant role in understanding human emotional states. With the advancement of AI and computer vision technologies, extensive research has been conducted in various fields, including improving customer service, medical diagnosis, and assessing learners' understanding in education. In this study, we develop a model that can infer emotions in real-time from a webcam using transfer learning with TensorFlow.js and MobileNet. While existing studies focus on achieving high accuracy using deep learning models, these models often require substantial resources due to their complex structure and computational demands. Consequently, there is a growing interest in developing lightweight deep learning models and transfer learning methods for restricted environments such as web browsers and edge devices. By employing MobileNet as the base model and performing transfer learning, our study develops a deep learning transfer model utilizing JavaScript-based TensorFlow.js, which can predict emotions in real-time using facial input from a webcam. This transfer model provides a foundation for implementing facial expression recognition in resource-constrained environments such as web and mobile applications, enabling its application in various industries.

  • Recent demands from construction industry have emphasized the capability for graduates to have improved skills both technical and non-technical such as problem solving, interpersonal communication. To satisfy these demands, problem-based learning that is an instructional method characterized by the use of real world problem has been adopted and has proven its effectiveness various disciplines. However, in spite of the importance of field senses and dealing with real problem, construction engineering education has generally focused on traditional lecture-oriented course. In order to improve limitations of current construction education and to satisfy recent demands from construction industry, this paper proposes a new educational approach that is Failure-Based Learning for using combination of the procedural characteristics of the problem-based learning theory in construction technology education utilizing failure information that has the educational value in the construction area by reinterpreting characteristics of construction industry and construction failure information. The major results of this study are summarized as follows. 1) Educational effect of problem-based learning methodology and limitation of application in construction area 2) The educational value of the information on construction failure and limitation in application of the information in construction sector 3) Anticipated effect from application of the failure-based learning 4) Development and application of the failure-based learning model

  • This research aims to produce and implement web-based continuing nurse education programs in response to nurses' educational needs, and to verify them, thus preparing for the times that the program will be offered via web. This research designed, produced and implemented 'emergency nursing' and 'medical fee schedule management' subjects based on Jung, In-seong's(1997) web-based instructional system design, and then compared the learning achievements of web-based learning group of 38 people with those of face-to-face learning group of 39 people. The questionnaire have been developed by these researchers to measure pre-learning knowledge on 'emergency nursing' and 'medical fee schedule management.' Data collected for this research have been given statistical analysis, using SPSS 10.0 for Windows Program. As a result of giving Mann-Whitney test, with respect to pre-learning prior knowledge level, there was no significant difference between the web-based learning group and the face-to-face learning group(Z=-.092, p=.926), while after completing learning, there was a significant difference in the learning achievements between the web-based learning group and the face-to-face learning group(Z=-2.406, p=.008). That is, this research revealed this: the web-based learning group and the face-to face learning group with both having no significant difference in the pre-learning level, after receiving the continuing education each with different methods(face-to-face education and web-based education), showed that the web-based learning groups attained higher learning achievements than the face-to-face learning groups. This result proves the effect of the web-based education to be no worse or even better than that of the face-to-face education, provided that choices of appropriate themes and quality courses composition, as well as systematic design development effective implementation are guaranteed.
