While films today offer spectacle to the viewers due to the advanced technique, the "Modern Cinema"-a term named by Deleuze- offers spectators an opportunity to think about what they observe and to have various filmic experiences through the shifting of time image within the film narrative, which has been rather neglected as it is just a form in the realm of classic narrative. Originally the shifted time image was a result of thinking about the identity of a film. But it has self-reproduced over and over, and now it has turned into one of cliches that narrative films take. In this sense, a Korean Melodrama "Sarang-ni" is discriminated from other films which take twisted time image as a convention. The film "Sarang-ni", instead of adopting established shifted time image, put us to the confused time arrangement and then it amazingly arouses emotional effect which it initially meant to convey. This journal analyzes how the time representation of operates in the film's narration, and consequently how the form affects the storytelling.

Objectives : It has been reported previously that the roots of Scutellaria baicalensis (known as Huang-Gum in Korean, henceforth referred to as S. baicalensis) could prevent neuronal cell death after global cerebral ischemia. In Genuine Korean medicine, S. baicalensis is known to relieve fever in upper body, and it was thus thought to be able to alleviate deteriorations in brain function. Methods : The protective effects of S. baicalensis against post-stroke memory retardation using 4-vessel occlusion model were examined in the present study. Results : S. baicalensis was shown to significantly alleviate the deficits in learning and memory by increasing the fraction of time spent in the quadrant in which the platform was initially placed ($34.9\;{\pm}\;3.2%$, p < 0.05) compared to that of the ischemia group ($28.0\;{\pm}\;2.5%$). The cytoprotective effect of S. baicalensis on CA1 hippocampal neurons was evaluated by measuring the neuronal cell density. Neuronal cell density in S. baicalensis extracts-treated ischemia group ($138.0\;{\pm}\;13.6\;cells/mm^2$) was significantly increased compared to saline-treated ischemia group ($22.1 \;{\pm}\;9.3\;cells/mm^2$, p < 0.05). In the study of OX-42 immunohistochemistry, S. baicalensis could decrease the micrgial activation in hippocampus after brain ischemia. Conclusion : These results may provide experimental support for the use of S. baicalensis in treating post-stroke memory impairment.

This study developed an English conversation learning program in immersive virtual reality (VR) environments and compared its effects with non-immersive VR environment using a computer monitor. The effects of the program was assessed using language anxiety and learning achievement. The results indicated that students' language anxiety decreased significantly after learning English conversation in VR environment, but there was no difference between immersive and non-immersive VR. The two VR conditions also produced similar learning outcomes. Future research on immersive VR need to address cyber sickness problems and develop effective learning contents in order to realize its potential for learning.

This study is to examine the effect of swimming exercise on the expression of c-fos, c-jun protein in rat hippocampus. 4-weeks aged rats and 16-weeks aged rats were used in experimental materials. All of two groups were classified into control and swimming exercise group. Swimming exercise was practiced for an hour a day. The results were got as follows after practical application in 1 day, 3days, 7 days. The expression of c-fos, c-jun protein was increased in all of the two experimental groups significantly in 1 day, 3days, 7 days. It was increased gradually in order of after 1 day, 3days, 7 days. There seems to be the effect of swimming exercise increasing the expression of c-fos, c-jun protein in hippocampus. Therefore swimming exercise can improve cognitive function such as learning and memory and prevent through activating immediate - early gene by swimming exercise. And it seems to have the positive effect on growth and recovery of nerve.

In arts, literary is always dealing human emotion and it makes a man weap or laugh among them. Hence, insight on how to write a poet is very effective in view of literary theraphy. The healing effect by literary theraphy on the invisible frame of life gives the resultant limitation using the poetry of a fixed form. Therefore, the search on how to write the free human immune system related on neurons or on how to deal with literary drugs makes our technique creatively developed. In this study, "the right writings for Korean poetry of a fixed form 'Writing Sijo'" is shown to make the literary theraphy more extensible and it is shown to makes the life quality more abundant. This paper suggests the right writing methodology of Sijo in such a view point.

It has been shown that in the modern society, teenagers do not read a lot of books. As basic research in order to attract teenagers to reading activities, the effectiveness of booktrailers in affecting reading motivation of teenagers has been studied. As such, 121 middle school and high school students were surveyed with respect to their (1) basic awareness of reading and booktrailers, (2) awareness thereof after watching booktrailers, and (3) reader behaviour reaction applied to AIDMA & AISAS sub-elements. Results show booktrailers to be much more effective in reading motivation than printed media such as book reviews. The preferred booktrailer type is the storyline type. The preferred elements of booktrailers are the storyline, background music, video effects, with their preference in descending order. Also, in terms of the reader behaviour reaction of the teenagers, very positive responses appear across all areas including attention and interest in the book, memories of the book, desire to read the book, search for information, and production of booktrailers. These results indicate that booktrailers can be utilized very effectively in providing reading motivation and in reading expression activities.
