Wearable health systems, aimed to provide individualized health management and better quality of treatment and care, are emerging. It enables low-cost, user-friendly and continuous healthcare at any time and at any place. This paper provides a review of wearable technology for health related applications, including the analysis of user requirements, the introduction of current achievements in wearable...
This paper proposes an efficient message authentication scheme providing non-repudiation of the smart metering service in Smart Grid. One of the main challenges in securing Advanced Meter Infrastructure is to accomplish message authentication and non-repudiation services in the metering service. Low power consumption of cryptographic operations in smart meter devices is another critical issue. The...
This paper describes a real-time monitoring system for hydrogen safety. Hydrogen energy is a clean and unlimited resource that replaces fossil fuels. However, hydrogen can explode in the density range of 4% to 75% by an ignition source. Therefore, safety devices or safety systems are necessary in the use of hydrogen energy. We aimed to develop a real-time detection module and a real-time monitoring...
Our society suffers from losses because of various and complicated disasters, so government organizations are struggling to mitigate disasters to prevent a growing number of casualties. Research on disaster risk warnings has been growing steadily, and at present there are a number of places equipped with the warning systems. However, this service is not applicable for small-scale disasters because...
This paper presents an analysis of thirty-two (32) ICT integration initiatives of different extent and reach coming from the private sector, academe, and the government over the past ten years. This study uses the ICT for Education (ICT4E) vision of the Philippine Department of Education as the framework in analyzing these initiatives. This study seeks to: 1) identify particular components of ICT...
In this paper, a discriminative training technique based on Gaussian Mixture Model (GMM) is proposed for detection and classification of abnormal acoustic events in indoor environment. In particular, we consider small indoor space such as vehicular scenes and develop a two-step procedure in which statistical mapping of acoustic features is followed by abnormal event detection. In the first step, Mel-...
Most music recommender systems produce a set of recommendation based on user's previous preference. But the information is not always attainable. Focusing on the fact that music listening behavior is a repetitive action of playing one song at a time, we predict the next item based on user's currently selected items even when user's previous preference is not available. We propose a simple but effective...
Thus far, most researches on the cooperative transmission focused on the reliability point of view, showing that we can significantly improve the reliability of data transmissions by the cooperative transmission. On contrary, in this paper, we study the performance of the cooperative transmission from different perspectives such as system throughput and fairness. We consider a three-node system that...
One of the method to improve performance of QoS is retransmission. For retransmission, one-way delay is essential because it should be known for correct retransmission. This paper proposes a one-way delay estimation scheme for efficient retransmission. In the proposed scheme, one-way delay is estimated by packet intervals. The simulation results demonstrate that estimated one-way delay is similar...
The schedule management of construction work is an important method to complete a construction project within a given period of time. There are attempts to carry out construction project management by IT and web basis. Thus we need to mediate the progress schedule and update to carry out well-planned progress management in a web page. This research proposes a method to manage construction schedules...
In this paper we analyze the validity of their model. For a kickoff, we prove the reliability of obtained questionnaire data by using the internal consistency method and split-half reliability method. And then, we will evaluate the validity of this model by the nomological validity method and the causality analysis for verifying the practicality and the effectiveness of the e-marketing process model.
Advancements in sensor technology have enabled the development of extremely small, low-power, low-cost sensing devices. Recently, wireless sensor networks (WSNs) with thousands of those tiny sensors have become increasingly common. The existing and potential WSN applications span a wide spectrum across various domains. In terms of data reporting schemes, WSNs can be categorized as time-driven and...
This paper presents a novel approach for contents-based medication image retrieval from a drug image database based on the shape and color information of the drug pill images. The shape information of the drug image represented as a signature and HSV color model from the images are used to distinguish a medication from a set of medication images. To retrieve an image from a large image database, we...
There are many attempts to optimize information retrieval using various social concepts such as social annotations and social book marking. This paper explores the convergence of the information retrieval technique, the social network and the context-aware computing in order to improve information retrieval services. We propose a new ranking algorithm for the context-aware information retrieval. To...
In estimating the number of failures using the truncated data for the Weibull model, we often encounter a case that the estimate is smaller than the true one when we use the likelihood principle to conditional probability. In infectious disease predictions, the SIR model described by simultaneous ordinary differential equations are often used, and this model can predict the final stage condition,...
Web services composition is a new software development paradigm, and it is a key point to achieve serviceoriented computing currently. For meeting the QoS requirements of consumers, this paper presents the QoS calculation rules and formalizes the services composition as the combinatorial optimization problem. In order to solve services composition, a new algorithm based on QPSO algorithm is proposed,...
This paper presents the condition and methodology that the library ought to have when the library is considered as an information recommendation organization. University library is expected to be in an educational standpoint, and expected to achieve the students support. This paper proposes the pushbased book recommendation system as a new library model which considers the students' data in the campus...
Many companies promote their products by using advertisements for increasing their incomes. Traditionally, advertisements have been placed on some paper madia such as newspapers and magazines. However, there are many advertisements on the Internet searching services sites such as Google, Yahoo! and MSN. Each searching site gains their incomes in the Internet advertisements. The Internet advertisement...
Collaborative activities of neurons in the network will be a typical working example in the biological system. Neurons look like to do respective different activities in the network. But, neurons communicate each other for performing an objective work. To control and process the all respective neurons efficiently in the neural network, the collaborative activities will give some clues for the principle...
Recently, it is not rare to see the news of the scarcity of employment opportunity of college students on TV and newspaper article. Although people have getting lost interest in the problem, they have actual hardship day by day. Primarily, the scarcity of employment is caused by the deterioration of the college's level and the regional characteristics, and also by the deteriorating working conditions...
