Even though there have been many efforts on driver's route recommendation, driver still should get involved to choose the driving path in a manual manner. Uncertain traffic information provided to the driver delays his arrival time and hence may cause diminished economic values. One of the solutions of reducing the uncertainty is to provide various kinds of traffic information, rather than send real-time information. Therefore, as the wireless communication technology improves and at the same time volume of utilizable traffic contents increases in geometrical progression, selecting traffic information based on driver's context in a timely and individual manner will be needed. Hence, the purpose of this paper is to propose a methodology that efficiently sends the rich traffic contents to the personal in-vehicle navigation. To do so, driver preference is modeled and then the recommendation algorithm of traffic information contents was developed using the preference model. Secondly, ontology based traffic situation analyzation method is suggested to automatically inference the noticeable information from the traffic context on driver's route. To show the feasibility of the idea proposed in this paper, an open API service is implemented in consideration of ease of use.

The networked home is connected to the external world using a high speed network. The devices inside the house are connected using a wired and wireless network. Acquiring the user data is an essential step for designing the user interface in user centered design. In networked home, the numbers of use cases are exponentially increased because connected use cases are considered. Because the user data for networked home are too complicated, they are acquired and analyzed by a structured methodology. We surveyed 40 people to acquire the context data home and analyzed by 5W1H (Who, Where, What, When, Why, How). We established a framework for the user data using tasks, user, time, space, objects and environment. The data for home context was structured by our framework. This framework makes simple the home context and is helpful for user interface design in home network.

Context-awareness system can provide an optimized services to users. Analyzing physical and complex circumstance elements which give direct or indirect influence to users can tell what users want. However, there are various situation informations around users and it requires high level technology to extract the service what users really want among those informations. The circumstance of the user can be changed from moment to moment, even the service what users want also can be changed in every minutes. Recently the researches to provide the service which a user demands has been progressed actively. Web based filtering method which reaches commercialization is a one of good examples. This method extracts necessary data according to users' demands from the documents on the Web or multimedia informations. However, there is a limit to use it to provide Context-awareness service because it extracts static data, not dynamic data. There is also other researches with a rule based filtering method in progress to filter situation information but this method doesn't have mechanism for dynamic data as well. We would like to solve these problems by providing a dynamic situation information filtering mechanism applying an weighted value about each property of objects and also applying Web based dynamic categories in this paper when unnecessary data should be filtered.

Recently, smart phones are widely used and as the phone sensors are evolved, we can get more various kinds of data from them. Using the data, many researchers take an effort to aware user's situation and the context-awareness for smart phones are actively applied to the real-world applications. However, to make an advanced information from sensing data need complex processing and analyzing information. Some of these computing processes are fully handled on smart phone or some data are processed by transferring to server. In this paper, we proposed a method for reducing user's context data generated on smart phone and designed a context generator. As a result, we can reduce a transmission data size and save a communication cost.

The phenomenon of money laundering through capital market instruments and various investment instruments in it is a challenge for law enforcement officials, particularly the Corruption Eradication Commission (KPK) in investigating money laundering crimes originating from corruption. This study aims to analyze comprehensively about: (1) implementation of policies on prevention and eradication of money laundering at the KPK in the context of handling money laundering on the capital market; and (2) an effective model for implementing policies to prevent and eradicate money laundering in the KPK in the context of handling money laundering on the capital market. By using a qualitative approach and Interactive Model analysis from Miles and Huberman, it was concluded that the results of the implementation of the policy of preventing and eradicating money laundering at the Corruption Eradication Commission in the context of handling money laundering crimes in the capital market had a positive impact on society, individuals and groups. The theoretical implications of the results of this study are related to the content of policy that is still relevant but for the context of implementation it needs to be refined or reconstructed by adding three elements, namely: communication, monitoring, and evaluation and security.

As the characteristics, attributes, and accepted way of media have been changing with newly emerging media, human recognition and the communication structure have also been changing. Media are not isolated from the others and emerge in the cultural context; With the drive to juxtapose the old and the new to be in diversified forms, the old media are utilized and improved. In this rapidly changing circumstance by the media, we attempt to theoretically explore the concept and characteristics of visual communication and the media related to augmented reality. Augmented reality does not create something out of nothing but renew the expression; Thus, it reforms the structure of communication. Therefore, there is a significance to look into theories of W.Benjamin, M.McLuhan, Norbert Bolz, and Jean Baudrillard who linked the past to the present in accordance with the new era of communication for us to find out the meaning of augmented reality in the current cultural context.

In recent years, various services in mobile environments due to the growth of mobile devices and related techniques like wireless networks. Furthermore, as the increasing communication traffic in cellular networks has become a new significant issue, many studies for device-to-device(D2D) communication and D2D-based cooperative services have been performed recently. In this paper, we design a smart agent system for D2D-based cooperative services and propose a dynamic service binding method based on service ontology. We classify roles of mobile devices for cooperative services by defining three types of smart agents, and construct a knowledge base in order to describe properties of 'service' unit. The proposed knowledge model, D2D cooperative service ontology, can enable a autonomous cooperative services between mobile devices by binding a requested service to the appropriate member device according to the real-time context in mobile environments.
