The declining birth rate and aging of society in Japan have progressed remarkably, presenting great difficulties in recent years. Particularly, the burden of nursing care is a looming difficulty. To resolve it, attention must be devoted to preventing dementia in elderly people. We developed an activity program using communication robots in a cognitive function retention class for elderly community residents, and investigated their reactions and impressions. Results show that many elderly people were interested in activities that were performed along with the robot. They gave the impression that they are more fun than just doing tasks with people. Activities with direct talking to and interacting with robots must be developed.

The electric loads of both power system and power consumers have non-stationary and uncertain characteristics that lead to difficulties in constructing an adequate model to accurately predict the load variations. This paper proposes a novel prediction model of short term load forecasting (STLF) for both system load and aggregated load of power consumers customers. The prediction method uses a particle swarm optimization based discrete wavelet transformation in multiple linear regression model (PSO-DWT-MLR) to capture the non-linear relationship between the load demand and the exogenous inputs. PSO was used to select the optimal combination of details and approximations data from DWT to construct an MLR model. Associated with actual weather information, validation of the proposed model is conducted in both system-side data set and end-user data set in Independent System Operator-New England (ISO-NE) and aggregated load data respectively. The results demonstrate that PSO-DWT can boost the performance of MLR for prediction of nonstationary load conditions and can provide more accurate prediction than existing methods.

Although questionnaire-based quantitative surveys can be implemented quickly and efficiently for groups, they are also known to have challenges, such as limited contents and skewed results due to intentional responses of the survey targets. In this regard, the projection method can be used to deeply understand the internal aspects of a client, including his/her unconscious side. If the relationship between the questionnaire and the projection methods can be shown and the classification of the psychological aspects that each method measures can be clarified, then the significance of the assessment that combines multiple methods will become more evident. In this study, we conducted a survey by using the combination of the Baum Test and the Group TAT, which was developed for group use based on TAT, one of the projection methods, together with SRS-18, which is a scale to measure stress reaction. We clarified the relationship between the tests and evaluated the psychological aspects covered in each test by analyzing the correlation among the measured aspects. This study was conducted with the cooperation of Kenta Koshimura, Ren Yamamura, and Takuya Oizumi, who are graduates of the Faculty of Information Sciences and Arts Toyo University.

The game-based learning already is an important research area of the learning technology. The learning outcomes is a critical factor to evaluate the effectiveness of the learning game. Recent studies suggested giving students more immersive experiences can improve learning. In this paper, a new framework of designing the learning games for giving students more game immersive experience is proposed. The new framework is designed based on the considerations of players' habits and complexity of the learning materials. We can use this framework to create a blended playing environments with the arcade game and the serious learning game. Based on the pilot test and using for teaching, the new approach can give students more and better immersive experiences in playing the game and get a better learning result.

The purpose of this paper is to improve the user experience of C language development environment for novices, Hello C, which has been uniquely developed by our previous researches. To examine effective user experience, we conducted two kinds of experiments. The one was the experiment with the learning task of fixing syntax errors to evaluate the method to convey error message. This experimental result suggested that the indication of the error message like scripting language may be effective even C language learning. Next, we also conducted the other experiment with the learning task of fixing I/O errors and examined the effectiveness to convey the closeness to the correct answer. This experimental result suggested that utilizing the concept of small steps could help to acquire the skill of programming.

Bluetooth Low Energy (BLE) has low power consumption, low cost, faster connection speed, and is extremely easy to deploy. The Beacon function in BLE is the basis for providing indoor positioning. Also, most of today's smart devices have Bluetooth, and all support Bluetooth 4.0 or higher, so BLE is very suitable for indoor positioning of smart devices. In addition to being able to be used for indoor positioning, the Beacon actively broadcasts its Beacon signaling regularly. Such a function can be used for advertising promotion in a designated area. Further, if a Beacon message contains the Uniform Resource Locator (URL) represents an Internet of Things (IoT) device, such a device can be called Web IoT device. It can be seen from the above that BLE's indoor positioning system can not only achieve positioning but also expand the characteristics to provide more diverse application services so that the positioning system has better value. Therefore, this paper takes the shopping mall as an example to implement the application service of integrating the Web IoT and BLE indoor positioning system to provide consumers with more application services, including indoor positioning, advertising push, and Coupon collection and use, Web IoT device display and trial and so on.

In the past twenty years, the internet has changed how governments interact with their citizens. However, there are disparities among different groups of countries when it comes to e-government and e-services. The current article aims to examine the current situation of e-services provided by local government units in Thailand. A purposive sampling technique was used, and a sample of 90 municipal websites was analyzed. The findings show that municipalities in Thailand provide a relatively limited e-services on their websites, implying that the implementation of e-government in the country has not much changed since the dawn of information age.

Enterprises operate in fast-changing environments nowadays and experience the continuous need to adapt to changing circumstances and new strategical and technological developments. This observation impacts how enterprise information systems are analysed, designed, implemented and used. Focusing on the analysis and design phases, conceptual modelling methods in the field of enterprise architecture management experience a continuous evolution in research and practice. Existing methods are re-purposed for specific requirements, new methods are developed/evaluated in concrete industrial settings and coupling/integration techniques support holistic viewpoints. Nevertheless, current practices in the design and enactment of such methods, and more specifically their metamodels, are inefficient with respect to agile and iterative considerations. Within this paper, a novel design approach for modelling method engineering is discussed that builds on the notion of meta-models as conceptual structures. Syntactic and semantic operation on these structures aim to facilitate the design process following the design science research methodology. The approach is evaluated by introducing a case developed as part of the European research project GO0D MAN. In the context of the project an enterprise architecture metamodel has been designed, developed and deployed that supports an integrated viewpoint of conceptual model artefacts coupled with operational data visualisations to assess the effectiveness of design decisions.

Caption Generation is one of the fundamental tasks combining computer vision and natural language processing. To achieve this goal, neural networks are employed to implement a caption generation system. In this paper, we proposed a caption generation system combining a CNN-based object detection system and a language model with a recurrent neural network. Especially, a vector which is sent from the object detection system to the language model is generated using an attention mechanism. Attention visualization can help us to understand the system focuses on a part of the input image in generating a caption. In the experiments, we evaluate the performance of the proposed system and discuss the effects of the attention mechanism in the image caption. Especially, the attention contributes to the improvement of caption generation but the attention is uncorrelated to system interpretation.

A technique called "Low-Cost Computing" has been attracting public attention in recent years. "Low-Cost Computing" is a method aimed at achieving the same level of performance of expensive commercial equipment or dedicated equipment by combining common, inexpensive equipment, software and services. One example of "Low-Cost Computing" is "virtual currency". Virtual currency often uses "distributed network" as an underlying technology. In a distributed network, data is stored using users' computers rather than a server for centralized data management. In short, virtual currency is realized by using the network to combine the users' computers. We think of this as "Network-Based Low-Cost Computing". There are many services using "Network-Based Low-Cost Computing", and they are becoming the mainstream of modern computers. As opposed to this, we propose "Infrastructure-Based Low-Cost Computing" in this research. "Infrastructure-Based Low-Cost Computing" proposed in this research means "combining commonly available devices and software to propose an environment for teleconference or remote class, and building an infrastructure with equivalent functionality to expensive systems or services". In this research, as the first step of this method, we aim to construct, with "Low-Cost Computing", a low-cost remote class environment which anyone can use. In this paper, we constructed a remote class environment with "Low-Cost Computing", and held classes at Toyo University. At the end of the remote class session, we conducted a survey on the remote class constructed in this research. Based on the survey results, we will summarize and consider the evaluation of remote class environment made available through "Low-Cost Computing".
