With the fast improvement of software and hardware technology of Virtual Reality, VR(Virtual Reality) film get attention for the new possibility of future film. Already, the production of virtual reality film festivals and Hollywood films is highly active, but it is still poorly related to virtual reality films in Korea. Due to this, this research analyze VR film with Realism films and Post-modernism films in four aspects that are film's frame(Mise-en-$Sc{\grave{e}}ne$), shot(montage), vew point and interactivity to deduct characteristics of VR film. Moreover, we also deduct an esthetical characteristic of VR films beyond the Realism films and Post-modern Films through analysing various VR films. This can be said as 'Digital Realism' that is come from the viewers' positive interaction and realization of Realism through Virtual Reality technology. There will be a successful development of VR film based on this research that analyse suitable directing method for Virtual Reality environment. At last, this research focused on characteristics of digital realism aspect for HMD based first person view VR animation .

This study focuses on the air to air missile control fin planform optimization for the minimizing hinge moment with the considering phenomena of fluid and structure simultaneously. The fluid-structure interaction method is applied for the fluid and structure phenomena simulation of the control fins. A transient-loosely coupled method is used for the fluid-structure interaction simulation because it is suited for using each fluid and structure dedicated simulation software. Searching global optimization point is required many re-calculation therefore in this study, a mathematical model is applied for rapidly calculation. The face centered central composite method is used for generating design points and the 2nd polynomial response surface is sued for generating mathematical model. Global optimization is performed by using the generic algorithm. An objective function is the minimizing travel distance of the center of pressure between Mach 0.7 and 2.0 condition. Finally, the objective function of optimized planform is reduced 7.5% than the baseline planform with satisfying constrained conditions.

Until the discovery of universal gravitation, a magnet had been considered to be a unique and magical stuff which exhibited an interacting force between two objects separated afar. Perhaps because of this belief, magnets were used widely as a medicinal stuff in East-Asia. In the present article, the records regarding the applications of a magnet for oriental medicine in written Korean history were surveyed. The records were categorized in terms of efficacy, prescription, and clinical case of taking-medicine. The records revealed that a magnet was used as an important component in the medicine for curing kidney filtering failure. Magnet was also prescribed to heal heart problems. Typical magnet-containing medicines included the SHINRYUKTANG, JIHWANGTANG, and INSAMBAEKHOTANG. Interestingly, it was revealed that some of the kings (Hyojong, Yungjo) in the era of Josun dynasty (1392-1910) believed the efficacy of the magnet-containing medicine and took it for curing their health problems.

This study aimed at analyzing journals and index terms, authors of the reformed theology and evangelicalism, neutral theological position by using bibliometrical analyzing methods. The analyzing methods are average linkage and neighbor centralities, profile cosine similarities. Especially, when analyzing the relationship between authors, we interpreted the research topic by finding the key shared index terms between the authors. In the journal analysis results, 9 journals were largely clustered together in the two clusters of the reformed theology and evangelicalism, but Presbyterian Theological Quarterly that is thought to be a reformed journal was clustered in evangelical cluster. In the index terms analysis results of the clusters, the reformed theology and evangelicalism were key words representing the two clusters. In the authors' analysis results, we had 9 clusters and the Presbyterian theologian studying the reformed theology had the four clusters and the non-Presbyterian theologian had the 5 clusters. Therefore, we consistently had the two clusters of the reformed theology and evangelicalism in all the analysis of the journals and the index terms, the authors.

This study aims to explore efficient foreign language learning paradigm with a focus on reading fluency and accuracy. From a perspective of language acquisition in the foreign language context, the priority in the L2 learning between accuracy and fluency has been a very important issue. Fluency becomes an important issue due to many researchers' interests in the L1 and L2 classroom. Although both accuracy and fluency are crucial, the paradigm shift from fluency to accuracy is necessary in the foreign language teaching. In this context, as an alternative methodology for L2 learners' fluency, the extensive reading approach is provided. A number of studies have suggested that extensive reading program could lead to improvement of L2 learners' reading rate and is an effective approach to improving general language proficiency.

With the development of hardware and 3D graphic technologies since the 1990s, video games have been evolving in the direction in which they wholly pursue illusions and movie formats, and thus they are considered to be media centered on spectacles. However, video games, due to their inherent characteristics, cannot be transparent media like the existing spectacular entertainments centering on optical illusions. In their structure, there can be found elements that continually disillusion players from visions. Strictly speaking, players are not lost in visions, but are kept a certain distance from internal contexts. Games rely not on illusion but on contracts with players which are similar to a kind of convention, clearing internal imperfections. This paper aims to identify and analyze disillusioning elements and discuss theatrical contacts between players and games. The purpose of this paper is to reconsider the awareness of video games as a spectacle entertainment and to help discover future directions for game culture.

Electron Energy Distribution Function(EEDF) were treasured In Radio-Frequency Inductively Coupled Plasma(RFlCP) using a probe rrethocl Measurerrents were conducted in argon discharge for pressure from 10[mTorr] to 4O[mTorr] and input rf power from 100[W] to 600[W] and flow rate from 3[sccm] to 12[sccm]. Spatial distribution of electron energy distribution function were measured for discharge with same aspoct ratio (R/L=2). Electron energy distribution function strongly depended on both pressure and power. Electron energy distribution function increased with increasing flow rate. Radial distribution of the electron energy distribution function were peaked in the plasma center. Normal distribution of the electron energy distribution function were peaked in the center between quartz plate and substrate. From the results, we can find out the generation mechanism of Radio Frequency Inductively Coupled Plasma. And these results contribute the application of a simple Inductively Coupled Plasma(ICP).a(ICP).

In this paper, we propose a new method for automatic classification of web documents using the degree of correlation between words. First, we select keywords from term frequency and inverse document frequency (TF*IDF) and compute the degree of relevance between the keywords in the whole documents,, using the probability model word that was closely connected with them and create a profile that characterizes each class. Finally, if we repeat the above process until lower than threshold value, we will make several profiles which are in keeping with users concern. And, we classified each document with the profiles and compared these with those of other automatic classification methods.

Environmental sculpture is not just a decoration for architecture. It is a work of art with public interest and one of the best ways to improve street landscape design. Place of installation is very important for environmental sculpture, because it has close relationship with its surroundings and regional context. Field survey was performed on Teheran-Street, between Samsung station and Yeoksam station, central business district of Kang-Nam where lots of major buildings are located. All the 28 environmental sculptures facing Teheran-Street were examined. Relationship between environmental sculpture and street landscape design was investigated by three different points of view, relationship with architecture, intimacy with pedestrian, and space defined by the environmental sculpture. Environmental sculpture needs its own space and appropriate place to have beneficial influence on the sense of place. Environmental sculpture is important factor to control the quality of street landscape design. We should have macroscopic approach to determine place of installation, method and material of Environmental sculpture.
