  • This study is for the characteristic of expression of exhibition presentation in 'The Korean peninsula' which is the Golden Lion Winner at the Venice Biennale in 2014. The Korean peninsula provides two opposite political and economic systems and adaptations of modernism through various multi media images. The curator, Minsuk Cho, presented cinema montage image of Collision for analyzing dynamic exhibition organization and provides the foundation of his theory from Bergson's image and duration to Deleuze's movement-image and time-image which is mentioned from Deleuze's book "cinema 1" and "cinema 2". Furthermore, the Korean peninsula has showed perception-image and affection-image from Eisenstein & Vertov's cinemathology and systemized exhibition presentation. The montage of Collision has maximized the movement from the variety and complexity in a collision and it made difference between information images which are space, time, emotion, intelligence, the tumult between subjectivity and objectivity, fragments from reorganizing itself, and distribution and art images. The limit of montage of Collision's dialectic is not only visual but also space from organic organization but the Korean peninsula overcomes its limit and shows leap of tactile perception and time-reflection from the montage of Collision's dialectic. Therefore, the exhibition of the Korean peninsula presents the conviction of adaptations of modernism.

  • The sense of touch has both objective and subjective characteristics. During hand evaluation of the fabrics. psycho physiological processes such as emotion and stimulation. On other site, the mode of touch (passive vs. active) is also capable to modulate somatosensory responses. I.e., suppress somatocensory perception during active electrocortical responses to passive and active touch of the textiles with different subjective emotional preference. The study was carried out on 36 female college students. Physiological signals were acquired by Grass and BIOPAC 100 systems with AcqKnowledge variables, namely heart rate (HR), respiratory sinus arrhythmia (RSA), pulse transit time (PTT), respiration rate (RSP) and skin conductance parameters (SCL, amplitude, risetime and number of SCRs) were analyzed for baseline and stimulation conditions. Analysis was manifested in a form of moderate HR acceleration. RSP increase, RSA decrease (lowered vagal tone), decreased PTT and increased electrodermal activity (increased SCL, several SCRs) that reflects general sympathetic activation. Parietal EEG effects (on contra-lateral side to stimulated hand)were featured by short-term alpha-blocking, slightly reduced theta, significantly increased delta and enhanced fast beta activity with few variations across stimuli. The main finding of the study was that most and least preferred textures exhibited significant differences in autonomic (HR, RSP, PTT, SCR, and at less extent in RSA and SCL) and electrocortical responses (delta, slow and fast alpha, fast beta relative power). These differences were recorded both in passive and active stimulation modes, thus demonstrating reproducibility of distinction between most and least emotionally preferred tactile stimuli, suggesting influence of psychological factors, such as emotional property of stimulus, on physiological outcome.

  • Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low-intensity direct current to cortical areas, thereby facilitating or inhibiting spontaneous neuronal activity. This study was designed to investigate changes in various sensory functions after tDCS. We conducted a single-center, single-blinded, randomized trial to determine the effect of a single session of tDCS with the current perception threshold (CPT) in 50 healthy volunteers. Nerve conduction studies were performed in relation to the median sensory and motor nerves on the dominant hand to discriminate peripheral nerve lesions. The subjects received anodal tDCS with 1 mA for 15 minutes under two different conditions, with 25 subjects in each groups: the conditions were as follows tDCS on the primary motor cortex (M1) and sham tDCS on M1. We recorded the parameters of the CPT a with Neurometer$^{(R)}$ at frequencies of 2000, 250, and 5 Hz in the dominant index finger to assess the tactile sense, fast pain and slow pain, respectively. In the test to measure CPT values of the M1 in the tDCS group, the values of the distal part of the distal interphalangeal joint of the second finger statistically increased in all of 2000 Hz (p=.000), 250 Hz (p=.002), and 5 Hz (p=.008). However, the values of the sham tDCS group decreased in all of 2000 Hz (p=.285), 250 Hz (p=.552), and 5 Hz (p=.062), and were not statistically significant. These results show that M1 anodal tDCS can modulate sensory perception and pain thresholds in healthy adult volunteers. The study suggests that tDCS may be a useful strategy for treating central neurogenic pain in rehabilitation medicine.

  • Objectives : This study was designed to find clinical factors that could be differentiated by the lateralization of lesion and also find clinical factors to predict the lateralization of lesion. Methods : The subjects were 65 cooperative inpatients and outpatients with non-traumatic subcortical cerebrovascular disease without neurologic and psychiatric history from January 1995 to September 1995 ; 48 patients in Kyung Hee University, Oriental Medicine Hospital, 35 patients in Anam Hospital, Korea University were examined as subjects, but authors excluded 20 patients whose data were incomplete or who had uncertain lesions on brain CT or MRI. The 65 patients were divided into three groups-group with left hemispheric lesion, group with right hemispheric lesion, group with both hemispheric lesion-according to the finding of brain imaging study. Their cognitive functions were evaluated by the Benton Neuropsychological Assessment(BNA), their subjective neurobehavioral symptoms by Symptom Check List-90-R(SCL-90-R), their objective neurobehavioral symptoms by Neurobehavioral Rating Scale, and their daily living functions by Geriatric Evaluation by Relative's Rating Instrument(GERRl) and Instrumental Activities of Daily Living Scale(IADLs). Results : The results were as follows : 1) The results of cognitive function test indicated that the group with right hemispheric lesion showed low functions in Tactile Form Perception(left), the group with left hemispheric lesion showed low functions in Finger localization(right), the group with right hemispheric lesion showed low functions in Finger Localization(left). 2) Though, there were little significant differences in subjective neurobehavioral symptoms, the group with right hemispheric lesion showed higher scores in all symptoms except hostility. 3) Though, there were little significant differences in objective neurobehavioral symptoms, the group with both hemispheric lesion showed higher scores in cognition, guilty/disinhibition, the group with left hemispheric lesion showed higher scores in lability of mood, the group with right hemispheric lesion showed highest scores in psychotism, neurotism, agitation-hostility and decreased motivation/emotional withdrawal. 4) There were little significant differences among three groups in Daily Living Functions, but the group with right hemispheric lesion showed the lowest functions in Instrumental Activities of Daily Living. 5) As a result of discriminant analysis on each factor's contribution to the prediction of lesion, Finger Localization(left), Phoneme Discrimination and Tactile Form Perception(right) showed that they had the potentiality to predict lesion. Conclusion : The results suggest that there are little significant differences among the groups of three non-traumatic subcortical cerebrovascular disease in cognitive functions, but the group with right hemispheric lesion showed more serious and various changes in subjective and objective neurobehavioral symptoms, and showed low functions in Instrumental Activities of Daily Living. This results suggest the possibility that the decline of the daily living function in the group with right hemispheric lesion were due to various symptoms, not due to cognitive dysfunction. The confirmation of the possibility should be worked out through the follow-up study of some groups containing cortical lesion. Apart from these findings, Finger Localization, Tactile Form Perception(right) and Phoneme Discrimination suggest that they can be used as clinically valuable cognitive parameters that predict the lateralization of lesion in non-traumatic cerebrovascular disease.

  • This thesis revolves around dual sensory therapy techniques using perception arts group counseling program focused on Popcorn Brain phenomenon. The program emphasizes intrinsic motivations for changes by activating the brain's dual sensory such as a sense of smell, tactile sensation and vision to deal with brain issues caused by digital devices addiction. Perception arts group counseling program is based on voluntary satisfaction of relationship desires, which can lead to a sense of accomplishment and belonging. Expression methods using dual sensory were presented as an alternative to resolving digital devices addiction by blending cognitive-behavioral counseling technique and group art therapy technique. The blending method offers an environment that can maintain a change to a senseless and lackluster brian due to excessive uses of digital devices, the main cause of Popcorn Brain, by emphasizing "thoughts${\rightarrow}$emotions${\rightarrow}$behavior" with a structural expression approach. If perception arts group counseling program is established in more systematic fashion and used strategically to offer such environment, it may be used as a treatment for brain issues described above. In addition, the program can be used a basis for encouraging voluntary treatment to satisfy relationship desires.

  • In the West, of the body's five senses sight is considered the most important but Ocular-centralistic thinking contains many issues. Privileging the subject and inhibiting interaction with the other senses, Ocular-centrism limits the experience of the world to the visual area. However, experiences can be understood as 'touching' various forms and are related to touch. With the heightened interest in the multi-sensuous side of the body contrary to Ocular-centrism, the intervention of the body in the external space has become an important issue in modern landscape architecture. This study explores the possibility of the haptic perception system that causes the active experience of a subject. Haptic perception plays a catalytic role leading an active experience of the subject and the subject experiences a sense of place through such haptic perception. By revealing what was known through the sense of touch through the concurrency and interaction of the various senses, haptic perception draws active participation The haptic perception system has been studied in various fields but has not been studied in the field of landscape architecture. Thus, this study discusses the aspect of haptic perception limited to landscape architecture shown before modernism. In a discussion on haptic perception, the concept of haptic perception is clarified through previous study reviews and literature and the characteristics of haptic perception are derived. Then, the problems of the Ocular-centrism system and the need for haptic perception are discussed. In the historical development process of haptic perception, the change process of the scopic regime is examined chronologically and the ways in which Ocular-centralistic thinking and anti-Ocular-centralistic thinking have been projected on the architecture and landscape architecture of each age are studied via literature and cases studies. The impact of the scopic regime on the landscape architecture field in the historical change process is examined.

  • The purpose of this study was to examine the consumers' image and factors of wear comfort, expectation and satisfaction levels of wear comfort of hiking gear in order to investigate the consumer perception of wear comfort of hiking gear. The questionnaires were distributed to 400 people in their 40s and 50s and, 260 of which were used to data analysis. The questionnaires were comprised of questions about the image, factors, expectation and satisfaction levels of wear comfort of hiking gear, and demographic characteristics. Data were analyzed by frequency analysis, factor analysis, reliability analysis, correlation analysis, ANOVA, Duncan test, T-test with SPSS 19.0 IBM for Windows. In demographic characteristics, 43.5% of respondents were male and people under 45 years of age were at 17.7%, those between 46 and 50 with 46.5%, those between 51 and 55 with 28.9%, those between 56 and 60 with 6.9%. The results of this study are as follows. Responses of male and female consumers to image of wear comfort were similar and ten or more mentioned reponses by men were well-being and freedom from pain, stretchability, light weight, absorption of sweat, softness. Wear comfort of hiking gear was shown to include mobility/pressure factors, moisture factor, psychological factor, tactile/keeping body temperature factors. It was shown that the expectation and satisfaction levels of wear comfort of hiking gear were relatively high and were not influenced by consumer's sex and age, but were affected by the objective of mountaineering.

  • Across the culture of Western Europe, dichotomy based on the visual sense has evolved. They believed eyes and ears requiring a distance related in recognition, are more developed than any other human senses in human body. Dominant position, as a condition to using a perspective, the eye has been just concentrated in the development of optical sight. But developed a variety of modern media, highlighting the importance of the other perception, it makes dichotomy to the expansion of perception over the single function of visuality. Recently, Guille Deleuze and Merleau-Ponty try to recover the sense of tactility segregated in skin from body keeping eyes for distance. By the result, the activity can be happened by being connected to the body rather than to eye in the space between the subject and object. From the phase of recognition where the human body tries to identify the object in the space considering a time, it will be changed for the subject to the phase of structure vice versa. Visual tactility is to eliminate the distance between subject and object. If the visual tactility is to erase the distance different from the visual in dichotomy, it will be occurred to having a tension and makes new relationship to work trying to move the subjective point of view in object. Like this evidence in analysis of architecture, it can be easy to find the Korean architecture rather than western architecture in terms of emphasizing the time and space. The fact, architecture of Lee Dynasty had been preserved and consisted basic form and style over the centuries makes us assume that visual tactility was considered as well as the visual sense. This study will be intensive in terms of visual and tactile inherent in the subject and how it is being connected to the movement in the space and time.

  • As virtual reality technology became popular, a high demand emerged for natural and efficient interaction with the virtual environment. Mid-air manipulation is one of the solutions to such needs, letting a user manipulate a virtual object in a 3D virtual space. In this paper, we focus on manipulating a remote virtual object while visually displaying the object and providing tactile information on the object's weight. We developed two types of wearable interfaces that can provide cutaneous or vibrotactile feedback on the virtual object weight to the user's fingertips. Human perception of the remote virtual object weight during manipulation was evaluated by conducting a psychophysics experiment. The results indicate a significant effect of haptic feedback on the perceived weight of the virtual object during manipulation.

  • This study is derived from a problem for the blind, how to recognize the space and how to find their way. Unlike ordinary people, the disabled people are closely related with special constructor environment using the other sense. Especially, to find his/her location, each person depends on the wayfinding ability as acquiring specific and various information,(e.g. recognizing figure by tactile sense, space size by auditory sense, direction by light from a window and regular noise, and existence of switch in a specific place.) Those senses help the person's wayfinding to his/her destination. The procedure of wayfinding are location, position, orientation, navigation, and movement. Consequently, construction for the people above mentioned can offer a design-guideline considering following factors, building arrangement considering regular noise, refurbishment, plan configuration of floor and wall-skin changed, circulation stream that maintains right angle by the regular noise in the building, enforcement location character by the inflow of the light into a crossing.
