Various image media such as game, animation, movie is developing. Goods called Figure as extension that use contents source of one kind in several forms were made, and is drawing a lot of popularity today. However, is handled as simple toy of children in the Korea. So, development of allied industry is slow. In case of overseas recognized the importance by means of marketing in contents industry. In this paper, explain meaning about figure and kinds of figure and through philosophical thought and theory, analyzed personality which figure has through scientific investigation(theory of Walter Benjamin, Freud and psychologists). Nowaday, figure industry of the Korea and other foreign country is continuing development. Especially the contents of Hanryu(Korea) star figure has lots of value and possibility of future growth.

During wireless network operations, adaptive power control is an effective way to enhance the network performance. In this paper, a new online power control scheme is proposed based on the evolutionary game theory. To converge a desirable network equilibrium, the proposed scheme adaptively adjusts a transmit power level in a distributed online manner. With a simulation study, we demonstrate that the proposed scheme improves network performance under widely diverse network environments.

Recently, increasing numbers of games and simulators are being implemented by employing the physically-based modeling techniques for better realism. In this paper, we propose the implementation techniques for overhead crane simulator based on ODE, the well-known open source dynamic engine. By comparing the dynamic behavior of the proposed system with a commercial engine based simulator, the physical plausibility and the effectiveness of the ODE based OHC simulator are verified. We expect the proposed the OHC simulator can be successfully utilized for virtual training in various educational institutes.

According to rapid advent of the smartphone, software technologies which have been used on PCs are being introduced into the smartphone. This paper introduces an implementation of an application software under the Android platform using morphing and warping technology. It composes two face images with morphing technology and also transforms an original face image using warping technology for fun. For this, the image is triangulated by Delaunay Triangulation based on control points which are created by simple LCD touches on the mobile device. The implementation case of this paper will be a good reference for the development of applications like games using morphing and warping technologies over Android platforms.

The Pythagorean formula for baseball postulated by James (1982) indicates the winning percentage as a function of runs scored and runs allowed. However sometimes, the Pythagorean formula gives a less accurate estimate of winning percentage. We use the records of team vs team historic win loss records of Korean professional baseball clubs season from 2005 and 2014. Using assumption that the difference between winning percentage and pythagorean expectation are affected by unusual distribution of runs scored and allowed, we suppose that difference depends on mean, standard deviation, and coefficient of variation of runs scored per game and runs allowed per game, respectively. In conclusion, the discrepancy is mainly related to the coefficient of variation and standard deviation for run allowed per game regardless of run scored per game.

This paper introduces that SSFE(Skeleton System for Facial Expression) to deform facial expressions by rigging of skeletons does same functions with 14 facial muscles based on anatomy. A three dimensional animation tool (MAYA 8.5) is utilized for making the SSFE that presents deformation of mesh models implementing facial expressions around eyes, nose and mouse. The SSFE has a good reusability within diverse human mesh models. The reusability of SSFE can be understood as OSMU(One Source Multi Use) of three dimensional animation production method. It can be a good alternative technique for reducing production budget of animations. It can also be used for three dimensional animation industries such as virtual reality and game.

Greimas's Carre Semiotique, as Floch showed in his analysis of car, has much effectiveness not only in theoritical aspect but also in practical aspect. This paper used his theory to analysis the value system of MMORPG. Lineage, the game known as representative game of 'nogada', was the starting point. WOW is supposed to have opposition relation with lineage and Ragnarok contradiction relation, and Mabinogi non contradiction relation. As well as games, the concepts that match to 'nogada' of lineage are also supposed. The value system of games is expected to be useful in further systematic analysis of games and also in practical area of design and marketing.

Problem posing activity of which a learner reinterprets an original problem via a new problem suggested, is a learning method which encourages an active participation and approves self-directed learning ability of the learner. Especially gifted students need to get used to a creative attitude to modify or reinterpret various mathematical materials found in everyday usual lives creatively in steady manner via such empirical experience beyond the question making level of the textbook. This paper verifies the possibility of lesson on question making strategy utilization for creativity development of gifted class, and analyzes various cases of students' trials to modify the rules of a board game called Rummikub in application of their own mathematics after learning What-If-Not strategy.

This paper describes the implementation of Direct3D interface library for Python language. DirectX is the most popular library used for 3D games and 3D modelings. However, softwares which use the library can only be developed in the environments provided by Microsoft like Visual Studios and .NET framework. The interface module for Python, this paper presents, will extend the coverage of the useful library DirectX to a language which is not fully supported by Microsoft. The interface techniques described here can be a guide to develop interface modules for other languages too, which make their language more powerful and extensible. This paper describes the implementation techniques to develop the interface module for Python, advantages and disadvantages.

This paper is a study of the investment dynamics focusing on crude oil supply by OPEC and non-OPEC. Oil supply capacity is first determined by a leader, OPEC, and by an aggregate that represents non-OPEC producers. OPEC wants to increase a gain from oil price increase while keeping its market share relative to non-OPEC's share. An investment rule model is developed for OPEC crude oil supply capacity in response to non-OPEC's decision. In presence of oil price uncertainty, oil price threshold is derived above which it is optimal for OPEC to expand oil supply capacity since otherwise the increased supply of non-OPEC results in weakening of OPEC market share in the world oil market. In addition, a lower threshold price is derived below which OPEC triggers a capacity reduction to regain its otherwise forgone profits. A simulation is provided for calculating the capacity expansion and reduction thresholds.
