Purpose: This study was done to investigate the effect of self-foot reflexology on peripheral blood circulation, peripheral neuropathy and to determine the feasibility of self-foot reflexology as a nursing intervention. Method: This was nonequivalent control pretest-posttest study with 76 patients with type 2 diabetes mellitus (ages between 40-79) recruited from public health centers in Busan city. Intervention was a 6 week self-foot reflexology, and outcome variables were peripheral blood circulation and peripheral neuropathy(tactile response to monofilament, intensity of symptoms of peripheral neuropathy). ANCOVA was used to do the statistical analysis. A.05 significance level was set for evaluating the effects of self-foot reflexology. Results: The self-foot reflexology was relatively effective not only in reducing peripheral neuropathy(especially tingling sensation and pain) but also in improving ability to sense the 10-g force monofilament. Conclusion: Even though self-foot reflexology was not effective in improving peripheral circulation, it had good effect on improving peripheral neuropathy. Therefore self-foot reflexology can be used as a nursing intervention program for promoting foot care for patients with DM patients.

Objective: The aim of this study is to investigate 1) somatotopic arrangement of the second and third fingers in SI area 2) difference of neural activation in the SI area produced by stimulation with different frequencies 3) correlation between the intensity of tactile perception by different stimulus intensity and the level of brain activation measurable by means of fMRI. Background: Somatosensory cortex can obtain the information of environmental stimuli about "where" (e.g., on the left palm), "what" (e.g., a book or a dog), and "how" (e.g., scrub gently or scrub roughly) to organism. However, compared to visual sense, the neural mechanism underlying the processing of specific electrotactile stimulus is still unknown. Method: 10 right-handed subjects participated in this study. Non-painful electrotactile stimuli were delivered to two different finger tips of right hand. Functional brain images were collected from 3.0T MRI using the single-shot EPI method. The scanning parameters were as follows: TR and TE were 3000, 35ms, respectively, flip angle 60, FOV $24{\times}24cm$, matrix size $64{\times}64$, slice thickness 4mm (no gap). SPM5 was used to analyze the fMRI data. Results: Significant activations produced by the stimulation were found in the SI, SII, the subcentral gyrus, the precentral gyrus, and the insula. In all participants, statistically significant activation was observed in the contralateral SI area and the bilateral SII areas by the stimulation on the fingers but ipsilaterally dominant. The SI area representing the second finger generally located in the more lateral and inferior side than that of the third finger across all the subjects. But no difference in brain area was found for the stimulation of the fingers by different frequencies. And two typical patterns were observed on the relationship between the perceived psychological intensity and the amount of voxels in the primary sensory cortex during the stimulation. Conclusion: It was possible to discriminate the representation sites in the SI by electrotactile stimulation of digit2 and digit3. But we could not find the differences of the brain areas according to different stimulation frequencies from 3 to 300Hz. Application: The results of the study can provide a deeper understanding of somatosensory cortex and offer the information for tactile display for blinds.

This paper is the output of a collaborative European project concerning the barrier free accessibility for disabled persons to regional and long distance trains in Europe. Disabled people represent around 13% of the population in Europe. This is approximately 63 million people. The range of disabilities includes people with reduced mobility including wheel chair users, viewing and hearing impaired people and other forms of impairment. Improving accessibility aims at contributing to the provision of public transport services to all citizens in an equitable way. The purpose of the project was to analyse and to evaluate the existing solutions at selected European railways for all required modules at the entrance (doors, information and safety solutions), to derive a design concept, to develop a mock-up in meeting the needs of rail travellers with the above mentioned impairments and to test it with user groups. The project also aims at deriving components for the determination of standards. The EUPAX Design Mock-up test was performed to verify the advantages of the layout of the train segment including the different modules such as access area (including the access door, gaps between platform and train as well as boarding aid devices), entrance vestibule, information systems inside and outside the train, emergency facilities, toilet with all conveniences and the additional test arrangements regarding push buttons, steps and emergency equipment. For this purpose a questionnaire was developed for the assessment of the EUPAX segment and the additional test arrangements. With the help of this questionnaire it was possible to execute a quantitative and qualitative evaluation. During three test phases 67 experts and handicapped persons from 6 countries have evaluated the Industrial Design mock-up based on this questionnaire. The test group covered persons from North (Denmark) to the South (Italy) and from the West (Spain) to the Middle of Europe (Germany). This is especially important for the generalization (harmonisation) of the results for all European countries. According to COST 335 the information for people with reduced mobility should be clear, concise, accurate and timely. So that all information can be received from persons, they must be transferred on at least two of the three possible ways (acoustical, visual, tactile), a so called "2-sense-principle". Based on the results ergonomic specifications/ solutions for the ergonomic design of the access area, the acoustic, visual and tactile information and the emergency devices including the emergency communication system were developed, related to the benefiting passenger groups.

Purpose: The aim of our study was to evaluate natural recovery of neurologic injury after minor dental surgery based on subjective neurologic evaluation. Materials and Methods: From December 2005 through July 2009, 30 patients from Seoul National University Bundang Hospital were identified as having been treated with minor dental surgery. The patients were composed of 12 men and 18 women, with a mean age of 50.6 years. The median duration of this study was 62 weeks. Results: The patients were treated by implants (17 cases), tooth extractions (6 cases), bone grafts (4 cases), inferior alveolar nerve transpositions (2 cases) and periodontal surgery (1 case) prior to the occurrence of altered sensation. Areas of altered sensation after minor surgery included the lip (36.7%), chin (30.0%) and tooth (21.7%), and at final follow-up, there was no change of ranking. Altered sensations expressed by patients included numbness (33.3%), discomfort (22.9%), relieving sense (14.6%), tingling (14.6%) and itching (14.6%). There was no change of ranking of altered sensation at the last follow-up. Patients experienced the altered sensation always (47.8%), during tactile stimulation (26.1%), when chewing food (13.0%), and talking (13.0%). Mean visual analogue scale (VAS) was $3.43{\pm}2.84$ for pain and $6.64{\pm}2.72$ for paresthesia. VAS of pain was decreased significantly between the first visit and the end of follow-up, and paresthesia also showed a significant difference. Conclusion: Altered sensations may occur at any time after minor dental surgery, but we observed that natural recovery of altered sensation occurred as time went on.

Purpose - The purpose of this study is to analyze the user requirements and developer requirements in virtual reality(VR), and suggest ways to increase the satisfaction of users who experience virtual reality. Specifically, focused on experience store of VR as a distribution retailer, user requirements were analyzed according to the results of previous research that the characteristics of Affordance, Presence, and Head Mounted Display (HMD) affect user satisfaction. Research, design, data, and methodology - Based on previous studies, in this study, we analyzed the importance of immerse, interaction, perception, and presence for the satisfaction of the user through the questionnaire, and the user experiences virtual reality (VR) The importance of HMD, Presence, Affordance, and experience satisfaction were analyzed. Based on this, we analyzed the user requirements and the developer requirements based on the questionnaires and interviews of the experts, starting from the user's desire or preference using QFD technique. Results - As a result of the analysis, the development factors that occupied a big part in the virtual reality field appeared to be visual. In detail, this showed that there was a lack of sense of presence for users. This should be improved. This paper shows that the requirements for visual, auditory, and tactile development are necessary. For the satisfaction of the users of virtual reality (VR) users, it is necessary to develop them according to their priority in consideration of importance and difficulty in the future. Conclusions - In this study, it was suggested that development according to priority should be considered, considering the difficulty level. Based on the results of this study, the following suggestions are made. First, we tried to search the list of user requirements as much as possible, but it is likely to change due to the development of VR technology. Therefore, it is necessary for developers to continually supplement user requirements with recent research literature. Second, development priorities according to difficulty level should be considered. This aspect should be considered in the actual VR development process, so if the numerical value of the difficulty is calculated, it should be presented in the research.

This study investigated the impact of long-term relationship orientation on emotional characteristic in fashion stores and relationship characteristic between middle-aged and senior women and salespeople. This study employed survey method with questionnaire. Data were collected from 579 women who were from the age of forty to seventy. The data were analyzed using statistic methods(SPSS 15.0 and Amos 5.0) such as frequency analysis, cronbach $\alpha$, exploratory factor analysis, second-order confirmatory factor analysis, confirmatory factor analysis and structural equation modelling. The findings of this study were concluded as follows; Firstly, the income significantly affected on emotional characteristics(p < 0.01), but had no significant effect on long-term relationship orientation(p < 0.05). The higher income, the more respondents exhibited positive attitude and sensitive emotional characteristics as a sense of sight, hearing, smell, tactile and feeling to salespeople in the fashion stores. The path of structural equation was implemented as income variables $\rightarrow$ emotional characteristics $\rightarrow$ (relationship with salespeople variables $\rightarrow$ )commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level. Secondly, senior group(55~70yrs) was more positive relationship with salespeople compared to middle-aged group(40~54yrs). The precondition of get satisfaction and feeling of being cared from the salespeople were critical for long-term relationship orientation. The path of structural equation was carried out as age variables $\rightarrow$ relationship with salespeople variables $\rightarrow$ commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level.

Fashion stores have to change to fit such the taste of individual customers taste and try to give unique experiences to the customers. They need to develop a special space that entertains customers, and entices them to visit and revitalize the off-line stores. This paper aims to analyze the experimental factors of stores, and how each of the factors impact customer experience in order to find out its effect on store satisfaction and store loyalty. Data was analyzed by using SPSS 18.0 and AMOS 18.0. Results of this study are as follows. First, Visual, Tactile, and Gustatory are the main senses that influence the emotional experience of the customers on a store visit. Second, three factors that influenced customer experience in experimental fashion stores are 'Causing Interest', 'Causing Concern', and 'Causing Relationship.' Third, the 'Causing Interest' factor and the 'Causing Concern' factor showed positive correlation with store satisfaction, while the 'Causing Relationship' factor did not impact store satisfaction, which affected store loyalty. Fourth, each experimental fashion stores can have different effect to consumer satisfaction and loyalty. Also, fashion store brands without an experimental store can cause various effects to consumers when a flagship store with an array of product information is formed. The conclusion drawn from this study will provide a guideline for fashion stores attract faithful customers by improving their store environment.

The nature is the foundation of human life and arts, and human beings have found order and principle amid ceaseless change and harmonization of the nature and diversified patterns and directly or indirectly applied the nature to interior through discovered principles. Interior space to which the organic factors of the nature is an expression of the vitality of the nature and expresses live forms as seen in change, development and growth of living organisms in addition to human feelings. The study aims to recognize the necessity of studies on interior space to which organic expressive characteristics of the nature are applied in uniformed space, suggest expressive characteristics and propose needed basic data required at a time of designing interior space. In this regard, the study has examined works by five contemporary designers including Zaha Hadid, Karim Rashid, Fabio Novembre and Nox with an aim to analyze expressive characteristics of interior design and figure expressive characteristics of organic design found in interior space. According to analyses on preceding literary studies and case studies (14 places), it has been found that organic expressive characteristics in interior space include vision, tactile sensation and auditory sense in terms of sensitivity, immateriality in terms of a property of matter, metaphor and abstraction in terms of the form of natural objects and non-linear curves and free curves in organic design. Organic spaces were characterized by symbolism, directionality, continuity, pattern and superimposition. This conclusion is expected to be useful in subsequent studies on the application of organic expressive characteristic factors at a time of planning interior space in the future.
