  • The purpose of this study was to examine the effects of using visual stimulation and gesture, namely embodied language learning, on learning achievement and learner's course interest in the EFL classroom. To investigate the effectiveness of the proposed purpose, thirty two third-grade elementary school students participated and were assigned into four English learning class conditions (i.e., using animated graphic and gestures condition, using only animated graphic condition, using still pictures and gesture condition, and control condition). The research questions for this study are addressed below: (1) What differences are there in post and delayed learning achievement between imitating gesture group and non-imitating one and between animated graphic group and still picture one? (2) What differences are there in course interest between imitating gesture group and non-imitating one and between animated graphic group and still picture one? The Embodiment-based English learning system for this study was designed by using Microsoft's Kinect sensing devices. The results of this study revealed that students of imitating gesture group memorized and retained better words and sentence structure than those of the other groups. As for learner's course interest measurement, imitating gesture group showed a highly positive response to attention, relevance, and satisfaction for curriculum and using animated graphic influenced satisfaction as well. This finding can be attributed to the embodied cognition, which proposes that the body and the mind are inseparable in the constitution of cognition and thus students using visual simulation and imitating related gesture regard the embodied language learning approach more satisfactory and acceptable than the conventional ones.

  • Purpose : This study aimed to evaluate the changes in visual perception and daily life activities after simultaneously applying the visual perception training program and transcranial DC stimulation. Particularly, this study tried to understand what changes in abilities among daily life activities influenced cognition. Methods : This study selected 50 dementia patients to achieve the objective. This study applied transcranial DC stimulation and a visual perception training program to a treatment group (n=25) and a visual perception training program to a control group (n=25). The intervention was applied five times per week and 30 minutes per session (total of 30 intervention sessions). This study measured visual perception functions and daily life activities using MVPT and FIM before and after applying the intervention. Results : The visual perception, mobility of daily life activities, cognition, and total score of the treatment group (n=25), which received the visual perception training program and transcranial DC at the same time, were significantly (p<.05) different between before and after the intervention. Moreover, when the visual perception and daily life activities of the treatment group and those of the control group after implementing the intervention were compared, they were significantly (p<.05) different between the two groups. Conclusion : The results of this study showed that the simultaneous application of the visual perception training program and transcranial DC stimulation was an effective means to enhance the visual perception and daily life activities of dementia patients. The results implied that transcranial DC stimulation, as well as the application of visual perception training program, as well as a visual perception training program, was effective for improving the visual perception functions and daily life activities dementia patients and simultaneous application of the two interventions would increase the effect even further.

  • Objectives : This study was designed to signpost the study of brain, intelligence and memory, while interpreting the concept of 'Chongmyeong(聰明)' neotrically and linking it to the clinic of Korean medicine. Methods : In this paper, the meaning of the word 'Chongmyeong(聰明)' is divided into two parts, intelligence and memory. We also explored the relationship between brain science and 'Chongmyeong(聰明)' based on complex system theory, cognitive science and embodied cognition. Results : Through the process of refining the concept of 'Chongmyeong(聰明)' neoterically, we proposed the new method to understand the concept of 'Chongmyeong(聰明)'. Conclusions : The concept of 'Chongmyeong(聰明)' should be interpreted not as a reductionistic viewpoint of brain science but as a viewpoint of brain science based on visual and auditory system and complex system. Human cognition is physically embodied in the environment, from the viewpoint of embodied cognition that it is constituted and formed in an interactive context with society and culture connected with the environment.

  • The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings with their materials and external appearance makes up the urban image. But still yet, it was not easy to evaluate the value of visual landscape of buildings with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. In relation to this kind of problems, it was tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watched the urban landscape constructed in a visual reality. The tested persons were 10 adult males and females with no color blindness and intact cognitive function. Light source with color filter was used for color environment in chamber room. The signal of EEG is analysed digitally and grouped into the $\alpha$ and $\beta$ waves. The result showed that relative power of $\alpha$ wave ratio increased in natural landscape scenary clearly. From these results it was possible to evaluate the human response, which was affected by urban color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

  • The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings deal with their materials and external appearance as an important factor, making up the urban image. But it was nearby impossible to evaluate the value of visual landscape with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. Such kinds of estimation can in some cases include arbitrary interpretations. In relation to this kind of problems, it is tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watch the urban landscape scenery constructed in a visual reality. The tested persons were 20 adult male and female with no color blindness and intact cognitive function. Light source with color filter was used for color environment in a dark soundproof chamber. The signal of EEG is analysed digitally and grouped into the ${\alpha}$ and ${\beta}$ waves. The result showed that relative power of ${\alpha}$ wave ratio increased in the natural landscape scenery with blue and green color. From these results it was possible to evaluate the human response, which is affected by urban and natural color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

  • More than 90 percent of traffic accidents were caused by human errors in driving situation. However, the ergonomic studies were not enough to prevent these human errors. Especially, drivers acquire more than 70 percent of information using the vision, and this shows the importance of consideration about the driver's visual cognition characteristics. Consequently, the driver's cognition time and the cognition accuracy were measured for the Instrument Panel(IP) of vehicle cockpit in this study. For the experiment, subjects were divided in two groups. The first group of subjects had their own vehicles and the driver license, and the second group of the subjects didn't have own vehicle but had the driver license. IP Images were used in the experiment and the each image was made by changing layout of objects within devices. The results showed that there were no differences for the cognition time and the accuracy between images within the group, and the results between the groups showed the same trend.

  • In architecture, Sensibility is the most basic thing in the environmental cognition. Emotion is the phychological or cognitive phenomenon of sensory changes. A cross-causal relationship is formed between the two, and they have a consensus in contact with humans and environment. Sensibility ever to serve as bundle and cognize as mutual superposition. Humans unconsciously perceive through the synesthesia that integrated all the senses. In this study, it has been identified as a result of the study, the architectural design through the sense must be design to the multisensory experience of the emotional design. Depending on the times change, it can know that the gradual changes based on the anthropocentric sense and sensibility. Emotional design in architecture shall ensure that a variety of experience through the multisensory. In this emotional design, multisensory design (or various sensory function) -visual & tactory or visual & auditory etc.- is required beyond the limitation of conventional visual concenturated. Therefore, In order to achieve the demands of the modern social objectives of sympathy or empathy for the human-centered design sensibility, the visual perception as well as a variety of sensory must be recognized that a combination of cognitive and functional. And the application of multisensory design is required to aim the synesthesia cognition.

  • As a result of the recent development and dissemination of HMD equipment, there has been an increase in the development of virtual reality contents. However most of these developments do not take differences of users' cognitive abilities and users' ability to immerse in and connect to these contents into consideration. In this study, we investigated the effects of visual factors of contents by conducting literature reviews, and conducted research on the correlation between visual factors and Virtual reality presence. While color and spatial factors had significant positive effects on content recognition and sense of reality, motion perception factors caused cognitive dissonance, which negatively effects the accurate recognition of contents. We were able to find that accurate recognition of virtual reality contents have a great impact on users' sense of reality.
