The sense of touch by natural wind is one of the most common feels that every person experiences in daily life. However, it has been rarely studied how natural wind can be reproduced in a VR environment and whether the multisensory contents equipped with artificial winds do improve human emotion or not. To address these issues, we first propose a wind reproduction VR system guided by video and wind capture data and also study the effect of the system on positive affect. We collected wind direction and speed data together with a 360-degree video on a yacht. These pieces of data were used to produce a multisensory VR environment by our wind reproduction VR system. 19 college students participated in the experiments, where the Korean version of Positive and Negative Affect Schedule (K-PANAS) was introduced to measure their emotions. Through the K-PANAS, we found that 'inspired' and 'active' emotions increase significantly after experiencing the yacht VR contents with artificial wind. Our experimental results also show that another emotion, 'interested', is most notably affected depending on the presence of the wind. The presented system can be effectively used in various VR applications such as interactive media and experiential contents.

With the modern society approaching, a lot of new paradigms have been created which can be explained by the existing space notions while suspicions on the true essence and existence of space have been raised. Ontology regards as the beginning the cause for a 'Field' which will be faced for the research of the essence of a space where 'being-in-the-world' exists. This study has analyzed the existing method of space construction in the spatial thinking and works of Peter Zumthor who mentioning ontological viewpoint as the physiological background of his works so that the ontological spatial concept may be clarified. The following is the study results. First, in order to construct the structures of his own designing into a 'Field' for experiencing the existential meaning, Zumthor chose a reductive pattern with the entire additional elements removed. The materials leading the subjects to call attention to memory and experience and the methods dealing with it enables the realization of various spatial essences. Second, the ontological event-system is required for the formation of relationship among beings. He tried to create a spatial meaning by introducing external environment into the inside and using the materials reflecting regional features and phenomenological empiricism through the multisensory experience. Third, he applied assimilation/insert/adjustment/formative change as the way of constructing the relationship between site and structure.

Purpose: The aging population is the quickly increasing in Korea. Since 2008, the National Long term Care Insurance, a number of long term care facilities have established during short time in Korea. Especially, the environmental assessment tool is important for managing healing environment in a long term care facility for the elderly. Alzheimer's Garden Audit Tool (AGAT) is used to assess whether a garden incorporates those elements and qualities as healing outdoor space. In this paper, we discuss the benefits, limitations, and future directions of the assessment tool for long-term care facilities. Methods : The AGAT audit was done through content analysis by 5 experts from diverse discipline as post occupancy evaluation of a long term care facility located in suburban area. The expert group was asked to describe their comments for modification and improvement in application of AGAT. Results : The results of this study show that it is necessary to refine the instrument's items to better meet the needs of the criteria and items for Korean culture-friendly tool. Especially, greenhouse elements (various plants, birds etc.), multisensory experiences, users-oriented space, programmed activities in garden, and hazards on pathway has somewhat limitation as measurement to assess outdoor of long-term care facilities in Korea. Implications : Consequently, AGAT could be applicable to evaluate the outdoor space of long term care facility in Korea with culturally sensitive revision.

This study aimed to develop a program that can be linked to gardening education activities in elementary students' curriculums and creative experience learning courses, and to apply the developed program to 6th graders in an elementary school located in Seoul. Research was conducted in a large category called biophilia, which named the instinct of human nature and nature throughout the research. The curriculum revised in 2015 was selected for the purpose of the garden education program based on the objectives and contents of the unit, and for the purpose of the class. In the process of developing and implementing the program, experience properties and elements were divided into direct and indirect experience of nature, including shapes and forms found in nature, air, water, plants, weather, animals, and natural materials. The results showed that the biophilic horticultural education program was effective in promoting students' multi senses. In the case of the experimental group, all the multi-sensory areas showed statistically significant differences, especially in the area of environmental literacy, environmental effect and emotional balance including plant cultivation knowledge. There was a relatively smaller difference in the dietary effect area than other areas because of no directional dietary program was included in the developed program. As a result, first, it is expected that the data can be utilized on site as a program or place of activity for students in upper grades. Second, it will be necessary to develop a more diverse program using other biophilic elements that were not covered in this study in order to maximize the effects of biophilic education.

This study investigates the characteristics of VR stores that emerged as new fashion communication media. Two case studies on Hyundai and eBay VR Department stores were conducted along with a discussion of the function and meaning of the fashion VR store. The results showed that both stores provide novel shopping experiences; however, the two were differentiated in terms of production method and technology implementation level. Functional aspects such as providing shopping efficiency and purchasing service was insufficient in both stores. Instead, they were complementing by means of product rotation, recommendation system, voice guidance, or linkage with an online shopping mall. In experiential aspects, both stores provided a strong sense of immersion. Hyundai VR store enhanced immersion with a high resolution image of a real offline store; however, it lacked in the ability to provide multisensory stimulation such as kinetic sense or auditory stimulation. The eBay VR Department store intensified the immersion experience by providing auditory stimulation as well as visual stimulation that enhanced the speed and distance sense through the utilization of animation. However, the extent of experience was limited in terms of agency and transformation because of the low interactivity found in both store systems.

A variety of methods are used in public advertising to make message persuasive. In order for posters to be more appealing, one good way is to use synesthesia. This study analyzed how synesthesia were used for effective communication. The case analysis is based on the prize winning advertisements chosen by the Korea Broadcast Advertising Corporation. According to the study, synesthesia maximize the efficiency of information delivery. Secondly, in the public campaign posters, sight was the most frequently used sensory element, followed by touch, hearing, smell and taste, respectively. Third, visual tactility was mostly used in nature and environment related posters to effectively deliver the messages. In the topic of social community campaigning, visualization of hearing was applied the most. Lastly, when more than three multisensory stimulations were present in the public campaign, the strongest sense stimulus played the largest part in making message delivery more efficient. The results of this study are expected to provide a scientific basis for future campaign posters that synesthesia expression elements are applied.

This study examined energy saving and elevating the worker's neuro energy (comfort, concentration, physical, and psychological stability) by compensating for the unpleasant tactile sensation to stimulate auditory and olfactory senses and reduce energy consumption. The experiment was conducted in an environment test room under the test conditions of temperature $25[^{\circ}C]$, relative humidity 50[RH%], illumination 1,000[lux] and air current speed 0.02[m/sec] by stimulating the auditory senses with a 1/f change in rhythm and the olfactory senses with an aroma scent. The experiment utilized the method of EEG, which evaluates human body's psychological status via tactile means, and the method of the vibra image, which evaluates the learning abilities, HRV and human body's psychological status via non-tactile means. The subjects were selected as eight university students (four males and four females) in their 20s, the type that have high relative ${\alpha}$(8~13[Hz]) activation in occipital lobe, which brings the highest level of mind stability and concentration, who had no difficulty in physical activities. The subjects' posture and physical activity was fixed to 1met - when the subjects are seated and relaxing in a comfortable environment - and their clothes condition was standardized as 0.7clo. As a result, the sentimental and psychological stability and concentration were the highest in the multisensory stimulation of jasmine scent and change rhythm of an a=1.106 sound source. In addition, under this condition, the relative $M{\alpha}$ and relative $M{\beta}$ increased by 70.49[%] and 89.72[%], respectively; the HRT decreased by 39.09[%]; and the fatigue and tension/anxiety decreased by 36.85[%] and 15.54[%], respectively.

The purpose of this study was to examine changes in the accuracy and range of produced pitch in children with cochlear implants (CI) after an interval-based singing program. A total of three children with CIs aged 5 received twelve 35-minute individual sessions two to three times per week. The interval-based singing program was composed with third, fifth, and eighth intervals and implemented pitch discrimination, pitch imitation, and singing songs with target intervals in a sequence. At pretest and posttest, the changes in accuracy of pitch production during pitch imitation and singing were measured. The results demonstrated that all participants showed improvement in pitch accuracy and produced the target notes with great similarity to the expected pitches in the original song. The range of produced pitch also increased after the program. The results indicate that sequential trials to imitate pitches in a multisensory environment to facilitate the processing of pitch information may reflect how this population perceives pitch information and assist children with CIs to improve their pitch accuracy.
