Recently, simultaneous localization and mapping (SLAM) approaches employing Rao-Blackwellized particle filter (RBPF) have shown good results. However, due to the usage of the accurate sensors, distinct particles which compensate one another are attenuated as the RBPF-SLAM continues. To avoid this particle depletion, we propose the strategic games to assign the particle's payoff which replaces the importance weight in the current RBPF-SLAM framework. From simulation works, we show that RBPF-SLAM with the strategic games is inconsistent in the pessimistic way, which is different from the existing optimistic RBPF-SLAM. In addition, first, the estimation errors with applying the strategic games are much less than those of the standard RBPF-SLAM, and second, the particle depletion is alleviated.

In this paper, we first introduce a new model of strategic Nash game with insatiability, and next give two social equilibrium existence theorems for general strategic games which are comparable with the previous results due to Arrow and Debreu, Debreu, and Chang in several aspects.

This paper discusses an academic study on electronic games and their incredibly vast and rapid growth over the years. It specifically addresses the evolution of electronic games from the 1960s to today, the ripple effects of electronic games, and the development of electronic game platforms. In terms of scope, the study first describes the ripple effects of the emergence of electronic games in chronological order and from the "immersion" and "convergence" perspectives, and then explores the evolution of electronic game platforms such as arcade machines, video consoles, personal computers, and mobile game devices.

The purpose of this study is to analyze the types of children's strategic thinking in the board games. Subject were 98 5-7-year-old children were participated in this study. Children divided by age were provided the same board game. Strategies used by the children to play the game were classified by age. The observational results were as follow; 1)Children used 9 strategies. Comparing to Kamii's study, children utilized 2 more strategic thinking. 2)Children used different game strategies based on children's age. Results showed that game strategies differentiated by child's age: five-year-olds used fewer strategies and older children applied a wider range of strategies.

The aim of this paper is to model North Korea and USA relationship since past until now. To this end, we have used game theory. The weakness of the existing models is that they have a static nature and can't analyze the changes of processes, strategies and results. The dynamic system of strategic games of which we have used in this article is a proper method to solve this problem. We have shown that South Korea and China play an important role in resolving the crisis.

본 논문에서는 온라인 게임에 관련한 국내외 연구동향과 이론들을 고찰하여 보고, 관련 문제에 대한 분석을 통하여 그 부작용에 대한 정책적 대안의 마련을 발제 하고자 한다. 온라인 게임은 이미 우리 사회의 중요한 문화 아이콘으로 자리 잡았고, 한류 열풍의 중요한 테마 중의 하나로써 우리의 대외 신인도 향상에 크게 이바지함은 물론 경제적 부를 창출해 주고 있다. 또한 온라인 게임과 관련 산업에의 투자는 상대적으로 부존자원이 부족한 우리나라의 훌륭한 블루오션점이 될 것으로 예상되고 있다. 그러나 이러한 순작용과 함께 예상치 못한 많은 반작용들이 발생하고 있는데 이에 관해서는 심심치 않게 언론에 보도되고 있으며, 그 심각성은 점점 증가하리라고 예견되고 있다. 이에 개별체계에 산재 되어 있는 온라인 게임 관련 분쟁의 통일적 해결 체제를 구축하여야 할 것이며, 이를 통한 예방적 효과를 거둠은 물론 합리적인 판단의 근거로 작용하게 해야 될 것이다. 또한 온라인 게임이 향후 국가전략산업으로써 한 단계 발돋움 할 수 있는 기회가 될 수 있는 기반을 조성해줘야 할 것이며, 이를 위한 다양한 부문의 학제간 연구가 시도되어야 할 것이다.

Serious game played with a computer in accordance with specific rules, that uses entertainment to further government or corporate training, education, health, public policy, and strategic communication objectives. The main goal of a serious game is usually to train or educate users while giving them an enjoyable experience. Serous games are video games with serious purposes such as teaching or training and whose principal aim is education. The major characteristics of serious games involve pedagogy which are all of the activities that educate, train, or instruct the player. Other characteristics of serious games are that they use entertainment principles, creativity and technology to build games that carry out serious purposes. This study is to introduce a serious game for the military training and to describe the elements of game design for developing it.

This paper proposes a strategic portfolio model for managing performance of online games. The portfolio matrix is composed of two dimensions: financial performance and non-financial performance. Financial performance is measured by the conventional measure, average revenue per user (ARPU). In terms of non-financial performance, five non-financial key performance indicators (KPIs) that have been widely used in the online game industry are utilized: RU (Register User), VU (Visiting User), TS (Time Spent), ACU (Average Current User), MCU (Maximum Current User). Data envelopment analysis (DEA) is then employed to produce a single performance measure aggregating the five KPIs. DEA is a linear programming model for measuring the relative efficiency of decision making unit (DMUs) with multiple inputs and outputs. This study employs DEA as a tool for multiple criteria decision making (MCDM), in particular, the pure output model without inputs. Combining the two types of performance produces the online game portfolio matrix with four quadrants: Dark Horse, Stop Loss, Jack Pot, Luxury Goods. A case study of 39 online games provided by company 'N' is provided. The proposed portfolio model is expected to be fruitfully used for strategic decision making of online game companies.

Purpose - This study involves the following questions: "Does internalization theory fully explain reality?" and "Which additional factors may add extra value to the theory?" To answer these, this study divides market entry mode into two steps, initial and subsequent and then, focuses on the subsequent distribution step; that is, the post-entry strategy after initial entry. In addition, this study relies on finding strategic orientations that affect the decision of post-entry into foreign markets. Research design, data, and methodology - To investigate this, this study examines 252 cases of Korean online games for each foreign market and the distribution mode at the product-team level. Results - The result shows that companies use different distribution strategies as a post-entry mode, like licensing, or joint distribution rather than exclusive distribution, through subsidiaries even if they already have wholly owned local subsidiaries which have enough experience and resources to select the entry modes among various types and then provide full commitment and control. Additionally, it finds that strategic orientation affects post-entry strategies differently. Conclusions - Therefore, this study is noteworthy and significant, as it practically extends the existing theories such as an internalization and distribution for decision making regarding the overseas expansion of entertainment businesses.
