The development of smart technology has brought the conversion of closed traditional e-learning contents into open flexible smart learning contents consisting of learner-centered modules, without the constraints of time and space by use of smart devices from the uniformed and passive classroom between teachers and learners. It has been demanded an open, personalized and customized teaching and learning contents of smart education and training systems according to wide supply of various smart devices. In this paper, we discuss about the status of the smart teaching and learning systems and analyze the characteristics and structure of the web contents for smart education and training systems by use of smart devices. And we propose a method how to block web contents, to extract them, and adapt personalized segments of web contents by adaptive algorithm into smart learning devices. We extract blocks from the web contents based on the smart device information and the preference information of the learners from existing web contents without the hassle of learners environment. After specifying a block priority from the extracted web contents by the adaptive segment algorithm, it can be displayed directly to the screen to fit the individual learning progress of the learners.

The purpose of web-sensor is to transmit the measured sensor data and the related information to remote user. Since the user exists at remote place, the sensor information must be trustworthy, and the diagnosis for sensors should be easy to handle. To make sure of these issues, IEEE 1451 for smart sensor had been presented in the past. This research proposes the smart web sensor. The proposed smart web sensor is based on IEEE 1451.0, therefore most of the sensor interfaces are able to be used, and could realize the smart sensor by using TEDS information. Also it has the user-friendly web-service by using XML so that the remote user can handle easily the every possible information related to sensor. This research presents reference model for smart web sensor, and to prove how valuable it is, web-service using gas sensor is implemented.

In this paper, we propose a Smart Adapted Service which can manage a schedule automatically. Smart Adapted Service gives a notice beforehand regarding information associated with the schedule, by searching the Internet. If the user has written down the name of goods or food which he wants to buy, Smart Adapted Service finds the most suitable store nearby him using the user's favorite list. The user's favorite list is created by Outlook Web Access System by analysing the schedule and habits of the user. User can access Smart Document System remotely through the Internet using Outlook Web Access System. We developed an Auto AP Roaming System for seamless communication and Smart Document System for arranging the information. We evaluated the system and verified that it is convenient to use and working well.

This study is for empirical verification of the influence of the introduction of smart phone on using the portal sites that were affected the most in the previous media environment. To achieve this, Web traffic data that are the result of smart phone users' practical Web uses have collected longitudinally and analyzed. The research results are the following: First, the use hours of portal sites have decreased about 15% and the page views have did about 35%, since using smart phones was diffused and habituated in earnest during the past two years. Using the community, news media, video, mobile, and game section of portal site sections have reduced. Second, the portal site portion of using smart phone Web is much more than that portion of using PC Web. More than two thirds of smart phone Web use traffic occurs in using portal sites, while more than one third of PC Web use traffic does in using that. Using the news media section is the most of using portal site sections on a smart phone. Third, since the introduction of smart phone, using the news media, communication, and life section of portal site sections have greatly increased, while the community, mobile, and game section have greatly decreased in the aggregate.

One shot tasks like a MERSC handling policy, a cinema poster, and so on are too small, diverse, and sporadic to make them as apps or web applications. They are usually shared as the form of notes attached in the field or messages in smart phones. In order to support inter-operability with internet web sites, QR/NFC tags are attached to them. What matters in the web technology is that HTML5 standard does not supply the accessability of smart phones' resources like a camera, an audio, magnetic sensors, and etc. In this paper, we propose a universal smart phone application for handling various one-shot tasks in the same UI/UX. One-shot tasks are described with HTML5 web documents, and the URL for the web documents are stored in QR/NFC tags. A smart phone scans a tag, and then the web document is retrieved and presented finally. QR tags can be delivered to other smart phones through messages or SNS. We solve the problem of HTML5 standard supplying a resource access library with javascrippts. We suggested the whole architecture and the internal structure of QR/NFC tags. We show that our scheme is applicable to make variable one-shot tasks.

Smart client is a term describing an application environment which delivers applications over a web HTTP connection and does not require installation and/or updates. The term "Smart Client" is meant to refer to simultaneously capturing the benefits of a "thin client" (zero-install, auto-update) and a "fat client" (high performance, high productivity). A "Smart Client" application can be created in several very different technologies. Over the past few years, ITS has started to move towards smart clients, also called rich clients. The trend is a move from traditional client/server architecture to a Web-based model. More similar to a fat client vs. a thin client, smart clients are Internet-connected devices that allows a user's local applications to interact with server-based applications through the use of Web services. Smart Client applications in BIT bridge the gap between web applications and desktop applications. They provide the benefits of a web applicationwhile still providing the snappy look and feel inherent to desktop applications.

Pervasive computing and Internet of Things (IoT) have recently received considerable interest to deploy solutions for the future Internet. Smart environments are integrated with Semantic Web to provide context-awareness to the processed information. Self-learning techniques have been adopted within smart solutions for efficient retrieval of data but do not process data with privacy parameters for in-place authorization. To overcome this issue, we present a novel approach of deploying access control as a service mechanism within Semantic Web based smart environment by using eXtensible Access Control Markup Language (XACML). The proposed XACML as a Service (XACMLaaS) approach offers fine-grained access control for protecting information within smart environment. In this paper, we have defined mathematical rules for each components of proposed access control service layer. These rules are for implementation of access control using XACML. The proposed approach allows the adaptation of authorization of information at component level and provides scalable solution for authorization policies and rule enforcement within smart environment.
