Demand for car navigation systems has been an explosive increase because of prevalence of owner-drivers, spare time spread, and so on. In addition, car navigation systems are achieving a rapid growth to be the important part of telematics industry with services such as real-time traffic information and DMB(Digital Multimedia Broadcasting). The network data, one of the composition components in car navigation systems, is most important component because that is abstract of real world road network and base data in pathfinding. However most of the car navigation systems have been stand-alone system. Thus user's network data becomes outdated according to the time passing and does not reflect the change of road information in real world. To overcome this problem, users have to update network data in car navigation systems periodically. This method is quite cumbersome process. For this reason, this study proposed a new update method to serve the difference network data on user's device and the real world in real time, and simulated to verify.

The purpose of this study is to infer how is the effect of a governmental funding project to graduate schools by taking an example of World Class University Project's potential impact on the change of world university rankings in an international university ranking survey. Systematic results show that WCU contributes to improving academic peer reviews for both individual and institutional standings and discipline-based rankings. The potential effect of improving world rankings of participating universities could be ascribed to relatively higher weight of the survey to international peer review and invitation of world class scholars to the participating universities, which is a core device of the project. This implies a need to affirmatively utilize WCU foreign scholars over the course of facilitating international academic networking. The results should also be taken into consideration by universities and the government when developing evaluation systems and restructuring the project.

Nowadays, the satellite communication systems provide worldwide or international service through organizations such as INTELSAT and INMARSAT, and the satellite communication technology has brought remarkable changes in the maritime mobile service as well as the fixed service on land. In our country, the international fixed satellite service via INTELSAT is no means inferior to the advanced countries, but to the contrary, we feel ashamed to admit that the facilities and technologies of our maritime satellite service via INMARSAT system donot keep abreast with the development pace of the world. This paper describes first the historical review of the development of satellite communication system is the world, then analyses the problems to bring the systems into wider use as early as possible, and filnally, I will make the following suggestions for the promotive direction on the INMARSAT systems. 1. Estabilishment of the earth stations at sea and on land. 2. Standardization of the qualification of the principal communicator on board. 3. Promotion of the international cooperation for the maritime mobile satellite service. 4. Establishment of the research institute on the INMARSAT systems.

There are problems in using existing fisheries maps, because of deterioration of paper maps, as well as various coordinate systems. In this study, accuracy of fishery maps in World Geodetic System are evaluated. Materials on fishery rights in the Jeollanam-do Province, a study area, used many kind of coordinate systems. During digitization, these coordinate systems have been converted and unified in one World Geodetic System, and one projection origin. In this research, the accuracy of the products of digitization is verified using DGPS surveying. The RMSEs are minimum of 4.62m(at the Younggwang Seas) to maximum of 17.47m(at the Jangheung Seas), and average of 11.97m. The results shows that the digitized fishery maps meet the accuracy standard of 1/25,000 digital topographic maps.

The purpose of this study was to highlight the necessity of a conceptual reestablishment of world university evaluations. The hitherto most well-known and validated world university evaluation systems such as Times Higher Education (THE), Quacquarelli Symonds (QS) or Academic Ranking of World Universities (ARWU) primarily assess big universities with quantitative evaluation indicators and performance results in the rankings. Those Systems have instigated a kind of elitism in higher education and neglect numerous small or local institutions of higher education, instead of providing stakeholders with comprehensive information about the real possibilities of tertiary education so that they can choose an institution that is individually tailored to their needs. Also, the management boards of universities and policymakers in higher education have partly been manipulated by and partly taken advantage of the elitist ranking systems with an economic emphasis, as indicated by research-centered evaluations and industry-university cooperation. To supplement such educational defects and to redress the lack of world university evaluation systems, a new system called 'U-Multirank' has been implemented with the financial support of the European Commission since 2012. U-Multirank was designed and is enforced by an international team of project experts led by CHE(Centre for Higher Education/Germany), CHEPS(Center for Higher Education Policy Studies/Netherlands) and CWTS(Centre for Science and Technology Studies at Leiden University/Netherlands). The significant features of U-Multirank, compared with e.g., THE and ARWU, are its qualitative, multidimensional, user-oriented and individualized assessment methods. Above all, its website and its assessment results, based on a mobile operating system and designed simply for international users, present a self-organized and evolutionary model of world university evaluation systems in the digital and global era. To estimate the universal validity of the redefinition of the world university evaluation system using U-Multirank, an epistemological approach will be used that relies on Edgar Morin's Complexity Theory and Karl Popper's Philosophy of Science.

This paper analyzed the narrative construction of ‘World of Warcraft’ which is very popular worldwide. Narratology and ludology should be interrelated in the larger area of art, rather than existing as separate fields. Dramatic narrative constructions of game would be made when the rules of game emerge with the circumstances of play. This paper reviews how 'World of Warcraft' generates its tremendous popularity through analyzing the overall narratives of 'World of Warcraft' and sub-narratives such as quest, PvP and hunting systems. The distinctive feature of this game is its well-designed story flow which is emerged by both underlying linear original story and non-linear multi-scenario that offers rich interactivities to the game users.

There has been a growing interest and enthusiasm for the application of virtual worlds in learning and training. This research proposes a design framework of a virtual world-based learning environment that integrates two unique features of the virtual world technology, immersion and interactivity, with an instructional strategy that promotes self-regulatory learning. We demonstrate the usefulness and assess the effectiveness of our design in the context of information security learning. In particular, the information security learning module implemented in Second Life was incorporated into an Introduction to Information Security course. Data from pre- and post- learning surveys were used to evaluate the effectiveness of the learning module. Overall, the results strongly suggest that the virtual world-based learning environment enhances information security learning, thus supporting the effectiveness of the proposed design framework. Additional results suggest that learner traits have an important influence on learning outcomes through perceived enjoyment. The study offers useful design and implementation guidelines for organizations and universities to develop a virtual world-based learning environment. It also represents an initial step towards the design and explanation theories of virtual world-based learning environments.
