A great many researches on affordance in HCI(Human Computer Interaction), product design, and cognitive science has been done investigated currently. In addition, the concept of affordances has been applied to games in the incremental trying to understand the relationship between gamers and systems. However, there are some problems to apply them to games because many researchers take ease to use, consistency, and usefulness to handle mainly in HCI rather than the property of the game into account. Consequently, the objective of the study is to investigate affordances in consideration of the features of the game, such as fantasy, variety, and fun based on the concept of them suggested in ecological psychology. A protocol analysis was conducted through the think-aloud method on the full gameplay session to platform action game as the basic genre of many game. The result of this research reveals that a static and movable affordances as a fixed state are discovered and transforming continously, appearing, and disappearing affordances as variable states are uncovered, and physical and cognitive affordances are observed. The result of this research is expected to propose the essential design guideline on the methodology of game design.

The current petroleum stockpiling by Korean government is based on the static concept of dead-stock. However, the recent changes in economic environment is requiring a transition to the dynamic concept of flow-stock. This study suggested selective trading strategies using basis of changing oil prices as an option for improving the economics of domestic strategic petroleum reserve (SPR), and quantitatively analyzed their effects. For this purpose, we tested the validity of selective trading strategies using the weekly spot and forwards prices of WTI for the period of October 1997 to August 2002. Summarizing the simulation results, the selective trading strategies would increase the expected values of profits and decrease their volatilities compared to those of traditional routine strategies. And, the adoption of trigger value could increase the improvements by the selective trading strategies. Based on the results, we suggest that, in order to improve the economics of domestic petroleum stockpiling, it is necessary to actively utilize the reserve facilities and the reserved petroleum with proper derivatives position.

This study is designed to introduce 'news literacy' as a theoretical framework to evaluate news education in digital age. Specifically, this study conceptually defined news literacy as news literacy self-efficacy and empirically tested how this variable is associated with other related determinants including users' news media consumption pattern, news knowledge structure on news content production, and involvement with news. The findings showed that users' 'searching/understanding' news literacy self-efficacy was positively affected by their knowledge structure and involvement with news, whereas users' 'sharing/expressing' news literacy self-efficacy was positively affected by their knowledge structure. The findings also demonstrated that users' 'searching/understanding' news literacy self-efficacy positively influenced their consumption of new types of news media, whereas users' 'sharing/expressing' news literacy self-efficacy positively influenced their consumption of traditional news media. As a result, this study practically suggests how news literacy is associated with the important factors affecting news consumption and news education.

This study begins with focus on the public opinion and political views on embracing Yemeni refugees in Jeju. The public opinion is demanding amendment or even abolition of the Refugee Act. The argument opposing Yemeni refugees is persuasive enough in terms of public order and safety, cultural conflicts and economic interests, but it is going against the universal and authentic values that must be pursued by a forward-looking society. It is natural that the power exerting political discretion keeps an eye on public opinion. However, no matter how many people express it, unjustified public opinion must not be a foundation for political decision. This study will examine the shadows of public opinion and related concepts for those reasons, and review Augustine's concept of 'love' as a value to refer to in making a communal decision. Conflicts lead to insecurity and rift. Without sensus communis (common sense), the rift will not be healed. This study raises the need to resolve such conflicting state and seeks insight from Augustine.

This study aims to propose improvement plans of the Humanities and Social Sciences research data archives in Korea. For this purpose, literature reviews were conducted to prove the importance of the Humanities and Social Sciences research data and establish a theoretical basis for the concept and requirements of data archives. In addition, analysis of the Korean Research Memory (KRM), case surveys for a total of 9 domestic and international archives, and in-depth interviews with a total of 10 researchers in the field of the Humanities and Social Sciences were conducted as well. As for the improvement of the Humanities and Social Sciences research data archives in Korea, establishing a cooperative system between the National Research Foundation of Korea (NRF) and the field of the Humanities and Social Sciences was proposed first for data archives of each project. Secondly, a conceptual model of research data archives was designed in such a way that the archives would perform according to a life cycle of research data in the cooperative system, all based on data curation.

This study analyzed the research trends and methodologies through meta analysis method on the issues of ICT policy and e-government in Korean major journals and proceedings including Korean Association of Public Administration (KAPA), Korean Association of Policy Studies (KAPS), and Korean Journal of Information Policy of NIA (National Information Agency). The results showed that methodology has changed from explorative study with conceptualization to experimental study with theoretical model and cases. Qualitative approaches including case studies and description with policy implications were employed more as analyses tools. In terms of contents, system effectiveness and e-governance issues prevailed in the early 2000s, and since then, it has changed into ICT-based social changes and looking for generalization of theories including e-democracy, e-service, e-participation, digital divide, and post-information society. Now we are facing another ICT revolution of social network via web3.0 and gov3.0 and it is time to open a new theoretical debate, deconstruction of discourse, and collaborative perspective among different disciplines.
