  • In this research, and investigation of the eye movement was performend when the objects perceived by the eye are three-dimensional objects, two dimensional images, and trhee dimensional images. This investigation was done by observing the EQG(Electro- oculogram) waves which were obtained from experiments. The observed waves were categorized into several groups. Differences among the waves were analyzed for each object and image perceived by the eye. In order to obtain waves for analysis, two kinds of experiments were performen. In each experiment, the saccadic eye movement and the smooth pursuit eye movement were considered as an independent variables. Waves obtained from the experiments were categorized into 4 types (Wave-1, Wave-2, Wave-3, Wave-4) depending on their characteristics. Unlike the other images, three dimensional image was revealed as a key factor for the active movement of the eye. Futhermore, a unique eye movement was observed in the case of three dimensional images where the focus of the eye was achieved through three steps.

  • Objective: Electroencephalogram (EGG)-feedback is a training procedure aimed at altering brain activity, and is used as a treatment for disorders like attention. The purpose of this study was to determine the effects of external focus of attention by EGG-feedback on balance in young adults. Design: Cross-sectional study. Methods: Subject were students in Sahmyook University. Fifty young adults in their twenties and thirties. Subjects were performed both with and without external focus of attention by EEG-feedback on the posture of standing and tandem standing. Participants were educated effort to maintain static posture when they were under internal focus of attention. Good Balance System was used for measurement of postural consistency upon the following force platforms. Results: Body sway decreased significantly both normal standing and tandem standing with external focus of attention by EEG-feedback (p<0.05). Conclusions: The results demonstrate that the benefits of an external attentional focus are generalizable to young adults. The external focus of attention outperformed the internal focus of attention on the postural balance (p<0.05). It is showed that external focus of attention significant effects on balance by revoked automatic postural control of movement. Furthermore balance might be improved by training with an external focus. Further study is required to develop for training as a method of preventing fall in elderly peoples.

  • Emotional interaction in virtual reality is necessary of social communication. However, social emotion has been tried to be less recognized quantitatively. This study was to determined social gaze of emotion in business domain. 417 emotion words were collected and 16 emotion words were selected to Goodness of Fit. Emotion word were mapped into 2 dimensional space through multidimensional scaling analysis. Then, X axis defined dimensions of cooperation, competition, and Y axis of low focus and high focus through the FGD. 52 subjects were presented to stimuli for emotion and gaze movement data were collected. Independent t-test results showed that the gaze factor increased in the face, eye, and nose areas at cooperation, and the gaze factor increased in the right face and nose areas at the low focus. It is expected that this will be used as a basic research to evaluate emotions needed in business environment in virtual space.

  • Head fixed type multi-focus display system using Galvano-scanner and DMD(Digital Micro-mirror Device), which is able to perfectly accommodate, can solve eye fatigue due to conflict between convergence eye movement and accommodation action in stereoscopic display. This system is able to accommodate through making convergence point about each view point and offering it in front of observer's pupil by using laser scanning method. In this paper, we analyzed laser scanning method of this multi-focus display system. And multi-focus display system based on this analysis was made, which showed that focus adjustment was possible through video camera. As a result, formation principle of view point of multi-focus system by laser scanning method was verified.

  • This paper explores the nature of multiple sluicing in English, which has two or more remnant wh-phrases in clause edge position. At the beginning part of the paper we argue against Nishigauchi's (1998) and Lasnik's (2007) Gapping analysis of multiple sluicing, which says that two remnant wh-phrases each actually occupies the left and right edge of a clause, with the in-between string of words undergoing Gapping. We rather argue that multiple sluicing in English is the same kind as found in Bulgarian and Serbo-Croatian. In other words, multiple sluicing in English is also derived by multiple wh-fronting which otherwise does not apply. We demonstrate that some important properties of the construction noted by Lmultiple sluicing, multiple wh-movement/fronting, sluicing, TP/IP-deletion, asnik (2007) under the Gapping approach to it can be accounted for in a principled way by our proposed analysis.

  • This study explores the background and the processes underpinning the educational reform movement based on local community. This educational community initiated the alternative education reform movement, which is referred to as the small school movement. A qualitative case study was implemented by collecting data from thirty articles, three focused interviews. This study drew out three key factors as the operation of educational community in regional area. First, it claimed a total of 30 papers related to the educational community for content analysis. Second, key words were derived in the local educational community context. They developed their own alternative educational programs, such as self-supportive meeting, season carnivals, community revitalization activities, and so on. Their focus was on finding out and establishing better educational relationships among the concerned communities. Third, the community continues to reinforce the internal rules and climate through meta-education, a process, in which education educates itself. As a result, they could enjoy substantial success in a visible educational community. This small school revival movement later grew into the new school movement. Furthermore, a variety of teachers, parents groups, and interested scholars have been engaged in the community movement through professional networking. This study suggests that the key innovator-initiated movement, which involves education reform, upgraded Korean education, and improved their own expertise and autonomy, is expected to be the first step to solve the current Korean educational problems by the educational community.

  • In most of the medical literature that discusses the common problem of movement in patients with cerebral lesions. This critical problem is ascribed to a mechanism involving uninhibited neural activity. The goals of neurological physical therapy are focus on reduce of muscle hypertonicity, facilitates muscle activities, and improve of performance in living environment. A variety of studies suggest that spasticity is a distinct problem and separate from the muscle weakness. It has become increasingly recognized that the major functional deficits following brain damage are largely due to negative features such as muscle weakness and loss of performance rather than spasticity. Adequate recruitment of prime mover, not release was able to carry out the movement tasks well. The strengthening exercise of spastic limbs on changes in muscle properties and performance skill, the repeated motor practice has been identified as crucial for motor recovery. This article support the concept that strengthening is an appropriate intervention to improve the quality of physical function in patients with central nervous system lesions. Further studies and therapeutic approaches should be efforts at improving motor neuron recruitment in agonist rather than reducing activity in antagonists while retraining muscle strengthening.
