  • This study had performed with purposes to analyze the influence of the change of vestibular sens, visual and proprioceptive sense to the postural sway, so as to supply the necessary clinical materials through developing the physical therapeutic interventions and assessment format for the diabetic neuropathy patients. The sample consisted of fifteen diabetic neuropathy patients with sensory disorder in their lower limbs and fifteen age-matched normal control group. Then the effect of the GVS and the visual cue open and closed to the postural sway were measured by CoP. The summary of the comparison results were obtained below. In the comparison of diabetes neuropathy patients group and age matched normal control group, however diabetes neuropathy patients group had a decrease in superficial tactile sense(p<.001) and nerve conduction velocity(p<.001), they were able to control the posture and walk. So it is, diabetes neuropaty patients had more disturbance compared with AMC group on at a hard surface, particularly in the visual cue open(p<.001) and visual cue closed(p<.01). Moreover, since diabetes neuropathy patients group had more differences in visual cue open and closed(p<. 01), GVS(p<.01), it meant that they're affected largely by vestibular sense, visual sense. In addition, since there're the largest change in doubled sense disturbance such as visual cue open and closed under GVS, it meant that compensation of other senses were quite important for the diabetes neuropathy patients' postural control. In the conclusion, diabetes neuropathy patients who decrease or lose the somatosensory system, sensory training of visual and vestibular system are likely to be quite essential to control the posture and balance.

  • Purpose : Resection of the epileptogenic zone in the parietal and occipital lobes may be relevant although only few studies have been reported. Methods : Eight patients with parietal epilepsy and nine patients with occipital epilepsy were included for this study. Preoperatively, all had video-EEG monitoring with extracranial electrodes, MRI, 3D-surface rendering of MRI using Allegro(ISG Technologies Inc., Toronto, Canada), and PET scans. Sixteen patients underwent invasive recording with subdural grid. Eight had parietal resection including the sensory cortex in two. Seven had partial occipital resection. Two underwent total unilateral occipital lobectomy. The extent of the resection was made based mainly on the data of invasive EEG recordings, MRI, and 3D-surface rendering of MRI, not on the intraoperative electrocorticographic findings as usually done. During resection, electrocortical stimulation was performed on the motor cortex and speech area. Results : Out of eight patients with parietal epilepsy, three had sensory aura, two had gustatory aura, and two had visual aura. Six of nine patients with occipital epilepsy had visual auras. All had complex partial seizures with lateralizing signs in 15 patients. Four had quadrantopsia. One had mild right hemiparesis. Abnormality in MRI was noticed in six out of eight parietal epilepsy and in eight out of nine occipital epilepsy. 3D-surface rendering of MRI visualized volumetric abnormality with geometric spatial relationships adjacent to the normal brain, in all of parietal and occipital epilepsy. Surface EEG recording was not reliable in localizing the epileptogenic zone in any patient. The subdural grid electrodes can be implanted on the core of the structural abnormality in 3D-reconstructed brain. Ictal onset zone was localized accurately by subdural grid EEGs in 16 patients. Motor cortex in nine and sensory speech area in two were identified by electrocortical stimulation. Histopathologic findings revealed cortical dysplasia in 10 patients ; tuberous sclerosis was combined in two, hamartoma and ganglioglioma in one each, and subpial gliosis in six. Eleven patients were seizure free at follow-up of 6 months to 37 months(mean 19.7 months) after surgery. Seizures recurred in two and were unchanged in one. Six produced transient sensory loss and one developed hemiparesis and tactile agnosia. One revealed transient apraxia. Two patients with preoperative quadrantopsia developed homonymous hemianopsia. Conclusion : This study suggests that surgical treatment was relevant in parietal and occipital epilepsies with good surgical outcome, without significant neurologic sequelae. Neuroimaging studies including conventional MRI, 3Dsurface rendering of MRI were necessary in identifying the epileptogenic zone. In particular, 3D-surface rendering of MRI was very helpful in presuming the epileptogenic zone in patients with unidentifiable lesion in the conventional MRI, in planning surgical approach to lesions, and also in making a decision of the extent of the epileptogenic zone in patients with identifiable lesion in conventional MRI. Invasive EEG recording with the subdural grid electrodes helped to confirm a core of the epileptogenic zone which was revealed in 3D-surface rendered brain.

  • Snoezelen, multi-sensory stimulation, provides stimulation through the visual, aural, tactile, olfactory, gustatory and proprioceptive senses. Its aim is to be a relaxing, feeling of safety, novelty and stimulation with no expectations for performance. Agitated behavior of people with dementia causes significant problems and distress for cares. The objective of this research study was to test the effects of Snoezelen room on physical and verbal agitated behaviors of people with dementia. Four patients participated five sessions in Snoezelen room of 'F' dementia care facility in Sweden. Assessment instrument was basically used Cohen-Mansfield Agitation Inventory-Short Form to be rated by caregivers on a 5-point frequency scale. Pre-trial and post-trial assessments were carried out during $27^{th}$ Aug.-$27^{th}$ Sept. 2007. Result shows that Snoezelen room has some short-term positive effect on agitated behavior even though there was a considerable variation individuals responded. This result adds to the increasing evidence that Snoezelen could be a therapeutic environment for the elderly with dementia. Further research study, with larger number of participation, and a control group is required to establish more scientific evidence of Snoezelen effects on health outcome.

  • In this research, we investigated the effect of three visual feedback conditions (direct viewing, one-monitor viewing, and tow-monitors viewing) on the task performance of human operator in teloperation task. The three different level of task difficulties under each concitions were performed by thirty-six subjects. The result of the experiments was analysed by the task difficulties, and the measurements of performance are the task completion time and the frequency of task errors. In a teleoperator, the participation of a human operator is always required, and the man-machine interface and the operator's abilities is an important issue. Recently, the different types of sensory feedback conditions(force, vision, sound, tactile, etc) for teleoperation is a very active research area in ergonomics. Among them, visual feedback conditon is an important sense that can provide the information of task environment. Therefore, the sufficient understandings and investigation for human ability under various visual feedback conditions is required to establish the efficient man-machine interface of teleoperation. The result showed that the visual feecback conditions and the level of task difficulties have a significant effect on the task performance. For three level of task difficulties, the task completion time was the shortest under the condition of direct viewing. The number of task errors under the conditions of direct viewing and two-monitors viewing were reduced by more than half compare to that of one-monitor viewing.

  • Although past design developments that emphasized only the outer appearances of products were mostly concentrated on the areas of forms and colors in an attempt to satisfy humans' visual needs, it is expected that future designs to come will go in the direction to stimulate more diversified human senses. This means expansions to the five senses including the auditory sense, the sense of smell, the tactile sense and the taste and even to the area of synesthesia where two or more senses are stimulated or coexist. Although the dictionary definition of synesthesia is a concept of arousing another sense through a sense, studies of synesthesia in design go one step further from here to mean compound senses, that is, the synesthesia in an expanded meaning to feel an object (thing) through many sensory organs simultaneously. The synesthesia in the expanded meaning is applying multiple senses simultaneously in recognizing one thing to comprehensively judge and feel the thing. Recent design trends are going in a direction to basically satisfy humans' visual needs through controlled forms and colors while inducing another new feeling through expressions of diverse feels of materials within existing forms. In this change of the times, studies on furniture designs are conducted through factors of in synesthesia linked with other senses and have an important meaning that can enhance the value of designs.

  • The purpose of this study was to investigate the content and presentation style of consumer information of Korean young casual apparel brand. To collect the data for this study, the representative 25 casual brand web sites were selected, based on major search engines. In addition, to investigate exact product information, four product categories, knit shirts and casual pants for men and women, were selected and the number of products was limited as maximum 15 products per each category. A coding instrument was developed to capture the consumer information, based on the instrument by Park and Stoel(2002). The Pretest was conducted to gauge inter-coder reliability and the results showed that inter-coder reliability was highly acceptable. The results of this study were as follows. Most casual brand web sites for this study were presented well in brand and customer service information. Especially, many web sites provided various engaging information such as various events(best dresser contest, date with a star, special gift) and useful multimedia file(MP3 music file, screen saver, movie, calender). However, product information was very lack in most web sites. Especially, sizing and fitting information and textile and fabric hand information were rarely provided. Therefore, this result showed that the web sites should provide more specific product information and develop devices to get tactile sensory and experiential information for enhancement of future e-commerce of apparel products.

  • Purpose: The aim of this study was to analyze Neonatal Intensive Care Unit nurses' behaviors while soothing newborns with bronchopulmonary dysplasia. Methods: An observational study was used to assess nurses' soothing behaviors. Data were collected from September, 2012 to March, 2013 using an audio-video recording system. Participants were eight babies and 12 nurses caring for those babies. After obtaining parental permission, the overall process of each episode from nurses' engagement in soothing to the end of soothing was recorded. Then a researcher interviewed each participating nurse. Data from 18 episodes were transcribed as verbal and nonverbal nursing behaviors and then categorized by two researchers. Results: There were 177 observed soothing behaviors which were classified with the five sensory-based categories (tactile, oral, visual, auditory, vestibular). Most frequently observed soothing behavior was 'Gently talking' followed by 'Removing irritant', and 'Providing non-nutritive sucking'. Nurses' perceived soothing behaviors were similar to the observed soothing behaviors except for 'Gently talking'. Conclusion: Nurses used diverse and mixed soothing behaviors as well as recognizing those behaviors as essential nursing skills. Nurses' soothing behaviors identified in this study can be used to comfort babies and to enhance their developmental potential in accordance with individual characterstics or cues.

  • Sensory attributes and preferences that contribute to consumer satisfaction with artificial leather were measured by subjective evaluation, and subjective hand and preferences were analyzed in relation to its use. Using tactile and visual senses, 50 experts in fashion and textile industry evaluated leathers classified into two categories, suede and polyurethane coated, according to different manufacturing methods. They answered questions on subjective hand and preferences of different artificial leathers of various fashion items (jackets, purses, bags, shoes, boots, furniture, etc.), using specific adjectives to describe the hand properties. As a result, it was found that the subjective hand properties of artificial leathers were related to 'Thickness', 'Fullness/softness', 'Surface contour', 'Stickiness', and 'Elasticity'. The leather type from different manufacturing methods influenced their perceived hand and preferences relating to use. By use, different hands were preferred. The preferences for jackets and furniture of suede type leathers were related to their surface properties, whereas the preferences for items of the other type of leathers were associated with their resilience. On the other hand, in the case of polyurethane coated leathers, the preferences for jackets were significantly affected by their thickness, while those for the other items were influenced by their resilience and surface properties.

  • In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. When it comes to the architectural materials, they can be conceived by visual and tactile sensory system and perceptional system which based on memory and experience. This study confirms how materials bring into effect on architecture in the sense of its design. The main subject of this analysis is expression method of architectural finishing materials. Also, this study finds out the relationship between finishing materials and the images of materials by analyzing the effect factor of architectural material expression with the perspectives of materials, formal and environments and by examining roles of the architectural materials in design. The material factor, in the expression of materiality, is how to make tectonic space and to vary the surface of building as finishing material design. The formal factor is related to set up the new direction in the architectural form and to create the dynamic and informal space. And the social and cultural environment as the effect factor gives new situation and context to architectural material expression. This principle enables us to use architectural materials as one of the important elements which express the whole characteristics of the area.
