This paper tried to analyse the factors influencing consumer trust and the relationships between cause variables and results in Internet Shopping Mall. In order to do so, this paper tried to analyse the trust factors in TV Home Shopping as well as Internet Shopping Mall in terms of cyber markets both. There found six factors ： perceived factor before purchasing, perceived factor after purchasing, perceived and emotional factors in the course of purchasing, positive and negative emotional factors after purchasing. These factors are correlated with Internet shopping variables and we can measure how Internet shopping variables can affect trust to the shopping mall. We can compare the trust factors of TV home shopping with those of Internet shopping mall and then we can activate Internet Shopping Mall. More implications of this study and further researches should be discussed in the future research.

The electronic commerce continues to grow dramatically. Also, consumer complaints and damages related to e-commerce grow rapidly. The analysis of consumer complaints showed that consumer of e-commerce tended to buy the various product categories including cloth and home appliance. The damages of delivery problem rapidly rose by 1,185.3%. In categories of transaction including of 'internet shopping mall', 'internet contents' and 'internet auction', about 90% of consumer damages was related to 'internet shopping mall' but consumer damages of 'internet contents' was anticipated to be increased in the near future. The major goods and services of damages was 'digital camera', notebook PC', 'internet game service' etc. Therefore, it is required to establish consumer protection measures to be prevent consumer fraud such as internet shopping mall, Halfplaza.com, and major goods and services of damages. Also, it is need to establish system of spontaneous consumer protection improving consciousness of e-commerce companies.

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.

All the countries in RA II (Asia Region in WMO) welcome the establishment of a Web site dedicated to agricultural meteorology, because it is believed that the best way to improve and speed up the flow of information is the use of the Internet and the establishment of a Web site. In providing recommendation for the promotion and improvement of the AgroMeteorological service in RA II, a couple of key suggestions were proposed: (a) Exchanges of data and AgroMeteorological knowledge between member countries and between RAs, (b) Exchanges of experts between member countries as a necessary way to share the knowledge, and (c) Joint research between member countries to solve common problems in AgroMeteorological affairs. In order to meet the above requirements for RA II, an AgroMeteorological information network will be the most critical and dynamic aspect in sustainable agriculture in this region. In addition, the establishment of a Core AgroMeteorological station, recommended by CAgM of WMO, will require its own information sharing systems for communication among member countries. Inevitable use of information technologies (IT) such as information networks, databases, simulation models, GIS, and RS for regional impact assessment of environmental change on AgroEcosystem will be enforced. Thus, the regional Internet-based Agrometeorological information network has been in place since 1999, though all contributions to it have been volunteered by individuals, institutes, universities, etc.

The Internet of Things (IoT) is a concept that describes environments where various things are connected to the Internet. These objects can identify themselves and allow other devices the identify them as well. DLNA focuses on delivering interoperability guidelines based on open industry standards in order to complete cross-industry digital convergence. This paper proposes a two-way DLNA Adaptor and addresses the methodologies of service interoperation of the media contents. In this paper, the designs of the components of the DLNA Adaptor are presented, and the conclusion provides general remarks and a discussion of future work.

Information service for the aged is a new challenge for public libraries in Korea. To develop an internet-based information service at public library perspectives, information sources, information need, and information seeking and using behavior are investigated. Interview survey is performed to 1060 adults aged 60 and over. Finding revealed that the respondents led to few channels to information except for mass media and informal oral communication. It ascertain ways in which 23% of the respondents currently use internet, and identify barriers of nonusers. The information need of the elderly are diverse, but health/medicine, news, hobbies, religion, leisure/travel are most identified need in descending order. Based on data analysis and previous research results, a cooperative service model consisting of information contents, online reference, interface design, and education is developed. Finally problems and suggestions for future improvement are discussed.

As the Internet has grown, energy consumption and GHG emission from internet use have become issues in recent years. On the other hand, such interest in greening the Internet has focused on edge devices, and there is a lack of deeper related studies of the energy wasted by excessive network-connectivity and the savings potential in wired network equipment. This study presents the background and reasonability of studies on the energy efficiency of wired networks in terms of the environment, economy and energy resources. The energy consumption and savings potential of network equipment were also estimated and the major factors of energy consumption was analyzed based on the data, and future studies for the Internet are presented.

IOT has evolved from the internet for human oriented, therefore our life is more advanced growth smartly. IoT is the network of physical objects or things embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator or other connected devices. Until now many researches have been studied for centering keyword for detecting emerging technology of future and scientometric analysis among the papers. This paper propose searching method of emerging technology for the IOT (internet of things) and smart device which are recently interesting area via dynamic analysis for keyword mapping.

The Internet of Things (IoT) is a new paradigm that is revolutionizing computing. It is intended that all objects around us will be connected to the network, providing "anytime, anywhere" access to information. This study introduces IoT with Kolb's learning style in order to enhance the learning experience especially for inclusive education for primary and secondary schools where delivery of knowledge is not limited to physical, cognitive disabilities, human diversity with respect to ability, language, culture, gender, age and of other forms of human differences. The article also emphasizes the role of learning style as a discovery process that incorporates the characteristics of problem solving and learning. Kolb's Learning Style was chosen as it is widely used in research and in practical information systems applications. A consistent pattern of finding emerges by using a combination of Kolb's learning style and internet of things where specific individual differences, learning approach differences and IoT application differences are taken as a main research framework. Further several suggestions were made by using this combination to IoT architecture and smart environment of internet of things. Based on these suggestions, future research directions are proposed.
