A Hypermedia-based Learning Environment (HLE) has shown potential in helping students improve their learning performance in terms of complicated subjects and skills, however, most students find it difficult to learn well in this kind of Open-Ended Learning Environments (OELE) due to a lack of Self-Regulated Learning (SRL) abilities. Manually adaptive scaffolding is labor-intensive and time-consuming, and Intelligent Tutoring Systems focus on the process of adaptive learning content and paths, not the SRL. Therefore, this paper proposes a Self-Regulated Learning System with Rule-based Learning Diagnostic Scheme (SRLS-RLDS) to automatically support adaptive scaffoldings for students in an HLE/OELE, where a rule-based approach and concept ontology is used to model teachers' diagnostic knowledge to help students regulate their learning. The proposed SRLS-RLDS was applied to a case of software learning, and the experimental results showed that students who studied with SRLS-RLDS adaptive scaffoldings had significantly higher post-test scores than those who studied without adaptive scaffoldings. Moreover, all students agreed that the proposed SRLS-RLDS scheme can effectively help them concentrate on learning content and to better understand the domain knowledge in their self-regulated learning processes.

This research focuses on a concept of location-based service (LBS) and further extend to design a set of smart phone application (APP) with mobile augmented reality about Yilan hot spring. The APP is divided into two parts: map module and augmented reality (AR) module. The map module enables people to search the hot springs' information and their corresponding positions by combining the application with the use of Google Map. The AR module uses the point of interest (POI) with two-dimensional virtual image in the real scene that allows people find the location. In addition, we provide the Quick Response code (QR code) for each of the POI, which assists the users to link to the original website of Yilan hot spring by scanning the QR code. The APP also provides the function of camera that allows its users to capture the photos and record the videos in this APP. By using this Mobile AR APP, people can search the information about Yilan hot spring anywhere and anytime.

Nowadays consumers' affective responses have become more and more helpful for developing successful products. Kansei Engineering (KE) is a challenging customer-oriented technology for product development in the intelligent age. It should not only translate the humans' feeling into design specifications, but also share classified design knowledge and integrate design features to get a new design scheme automatically. In this paper, an ontology-based systematic approach is proposed to establish a Kansei Engineering System (KES). The approach is based on a hierarchical ontology model and a feature combination mechanism. In our ontology model, design elements and items are divided into several hierarchies according to the expertise and the results of statistical analysis. The source data is from Kansei Evaluation Experiment. The classification of design features is used to decide the priority during feature selection and combination. In the present study, the hierarchical model is applied to establish an intelligent system for card design to demonstrate the effectiveness of the proposed approach.

Affective computing is a newly trend the main goal is exploring the human emotion things. The human emotion is leaded into a key position of behavior clue, and hence it should be included within the sensible model when an intelligent system aims to simulate or forecast human responses. This research utilizes decision tree one of data mining model to classify the emotion. This research integrates and manipulates the Thayer's emotion mode and color theory into the decision tree model, C4.5 for an innovative emotion detecting system. This paper uses 320 data in four emotion groups to train and build the decision tree for verifying the accuracy in this system. The result reveals that C4.5 decision tree model can be effective classified the emotion by feedback color from human. For the further research, colors will not the only human behavior clues, even more than all the factors from human interaction.

As smart phones have become prevalent, demand for mobile service on LTE networks has increased. As more mobile devices use wireless service, more authentication signaling results. Authentication is an important factor in wireless networks when identifying devices. This paper analyzes previous patterns of authentication during external network access. Fast wireless authentication service is proposed with minimal cost of signaling between the authentication server and external network. The rate of authentication in LTE networks is shown using mathematical modeling as well as changing signaling costs for authentication in various environments. The optimized number of authentication data calculations proposed in this paper shows that authentication signaling is cost effective.

The main purpose of this study was to investigate the influence of scaffolding and self-efficacy on students' programming learning performance in robotics learning environment. There were 89 junior high school students participated in the study. The results indicated that there is significant interaction between scaffolding mechanism and learning motivation on students' learning performance. The introduction of design journal did not have a significant effect on the learning performance of students with high self-efficacy, however, design journal had pronounced benefits for students with moderate self-efficacy. According to the findings, we proposed some directions for future studies.

The global market of electrical and electronic equipment (EEE) has increasing rapidly while the lifespan of these products has become increasingly shorter. E-waste is a huge problem when it's not properly disposed of, as these devices contain substances that are harmful to the environment and to human health as they contaminate the land, water, and air. This paper tends to highlight e-waste problem and harmful effects and can grasp the extent of the problem and take the necessary measures to solve it in Mongolia and to improve standards and human health.

A tool for efficient team formation based on students' proficiency and their communication in social networks is demonstrated. An experiment was conducted using two separate group discovering mechanisms with a pool of 68 students in two subjects. The proposed tool was used to discover groups in the experimental group with 31 students who followed the subject Object Oriented Analysis and Design and the grouping mechanism available in Moodle was used in the control group of 37 students who followed the subject Project Management during four weeks in the Spring semester of the 2013/ 2014 academic year. The study was carried out in accordance with a quasi-experimental research with a pretest and a post test design. The result indicates that small grouping based on the algorithm has better outcome.

This paper proposes a semantic overlay architecture design in unstructured peer-to-peer network environments. According to semantic distances based on feature similarity of files in a system, this design organizes a semantic peer-to-peer overlay that is capable of delivering query messages to neighboring peers in semantic proximity. In addition, this paper develops a deterministic search approach that can perform content search in a parallel manner over a semantic overlay. Extensive simulations are conducted to examine the proposed deterministic search mechanism in unstructured peer-to-peer networks. Experimental results show that this mechanism can provide satisfactory search services with cost-effective performance in terms of message cost, search latency and hit ratio.

Low energy consumption is a common design objective in energy-constrained Wireless Sensor Networks (WSNs). It is therefore crucial to accurately estimate the node energy consumption throughout the WSN design phases, particularly in the network layout optimization. In this paper, the node energy consumption is estimated with a discrete-event network simulation that provides realistic estimation values by capturing the dynamics of wireless communication protocols. A non-trivial WSN simulation requires a significant amount of time which can adversely affect the overall result of the layout optimization. Therefore, the network is simulated with a balanced simulation granularity to achieve high estimation accuracy and low computational complexity. A case study of Structural Health Monitoring is conducted to evaluate the discrete-event simulation approach. We compare the optimization results with those obtained in a previous work where the network energy consumption is obtained via simple communication models.
