The riding comfort problem for railway vehicles of conventional line becomes increasingly important under the influence of the opening of Kyungbu high-speed and high-grade railway in 2004. Meaning of the term "riding comfort" of passenger train varies widely. In a narrow sense, the riding comfort means the comfort related to the vehicle vibration. But in a broad sense, the riding comfort means the comfort related to the cabin temperature, noise, illumination, smell, air-conditioning, etc. In this study, the riding comfort in a broad sense is treated and the direction of research for improving the riding comfort is presented.

This article addresses the possibility of developing a new art appreciation method using olfaction, which was not previously considered an important sense in expanding the cultural enjoyment of visually impaired people. The human olfactory system is a faculty that is not considered very important in modern society; however, this is due to cultural factors, and from a biological point of view, the human sense of smell has sufficient potential for practical application. In this study, it is assumed that when various types of scent are perceived through this sense of smell, each has its own unconscious relation to color and concept, which researchers have termed "color directivity" and "concept directivity." Through experiments, the researchers found that some specific scents have color directivity and concept directivity, and in using these scents, they succeeded in delivering information about colors used in artworks to the visually impaired. Based on this study, we hope to continue our research on the use of color-concept directional scents that can convey the brightness and saturation of colors and more diverse hues.

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.

Many insects such as mosquitoes cause life-threatening diseases such as malaria, yellow fever and West Nile virus. Malaria alone infects 500 million people annually and causes 1-3 million death per year. Volatile insect repellents, which are detected through the sense of smell, have long been used to protect humans against insect pests. Antifeed-ants are non-volatile aversive compounds that are detected through the sense of taste and prevent insects from feeding on plants. The molecular targets and signaling path-ways required for sensing insect repellents and antifeedants are poorly understood. Transient Receptor Potential (TRP) Ca2+-permeable cation channels exist in organisms ranging from C. elegans to D. melanogaster and Homo sapiens. Drosophila has 13 family members, which mainly function in sensory physiology such as vision, thermotaxis and chemotaxis. G protein-coupled receptors (GPCRs) initiate olfactory signaling cascades in mammals and in nematodes C.elegans. However, the mechanisms of G protein signaling cascades in insect chemosensation are controversial. In this review, I will discuss the putative roles of G protein-coupled receptors (GPCRs) and Transient Receptor Potential (TRP) channels as targets for insect repellents.

For video reality improvement, there has been much advancement in the methods of providing visual, auditory, and tactile information. On the other hand, there is little research on olfaction for video reality because it is difficult to define and knotty to manipulate. As a first step for video reality improvement using olfactory information, this research investigated users' acceptability of smell when they watch videos of various kinds and then classified the video clips based on their acceptability of different criteria. To do so, we first selected three questions of whether the scene in the video appears to have an odor (odor presence), whether a matching odor is likely to improve a sense of reality (effect on sense of reality), and whether s/he would like a matching odor to be present (preference for the matching odor). Then after collecting 51 video clips of various genres that would receive either high or low ratings for the questions above, we had participants to watch the videos and rate them for the above three questions on 7-point scale. For video classification, we paired each two questions to construct 2D space to draw scatterplot of video clips where the scales of the two questions represent X or Y axis. Clusters of video clips that locate at different quadrants of the 2D space would provide important insights in providing olfactory information for video reality improvement.

As senile diseases increase with the aged increasing rapidly in an aging society, implementation of the aged long-term care insurance have an effect on the aged care and treatment. Though a decrease in prevalence rate can reduce social costs, the significance of that is overlooked. Especially, a program for a slight Alzheimer's disease and senile demetia in the spot of care facilities and welfare organs is nothing or a few programs which use only fragmentary techniques. So, In this paper, we propose a five-senses stimulation program for preventing senile dementia disease. It includes twenty processes stimulating five senses through proper harmony of senile dementia disease prevention techniques - hand exercises(sense of touch), remembrance therapy(sense of sight), cure recreation(sense of taste), music therapy(sense of hearing), gardening remedy(sense of smell).

Multi-sensory design results from sensory design paradigm and image centricism, which stimulates 5 sensation; visual, auditory, haptic, smell and taste sensation when we experience environment. This is helpful for designing outdoor space considering integrated sensation not only visual and auditory sensation as well as for improving visitor's satisfaction. Therefore, this study mainly intended to analyse the multi-sensory preference and the image influence of outdoor leisure space. For these purpose, this study selected 3 leisure spaces around Seoul city; Gwan-ak mountain(the type oriented natural resource), Insa-dong(the type oriented cultural resource) and Seoul land as theme park(the type oriented facility) and a survey was performed with a total of 204 visitors at the above spaces in winter and summer. The results of this study indicate that visual sensation was evaluated most high at 3 outdoor leisure spaces in both winter and summer. Visitors at Gwan-ak mountain and Seoul land prefer visual and haptic sensation, but visitors at Insa-dong prefer visual and haptic sensation in summer, visual and taste sensation in winter. Above all, this study led the designer to consider diverse sensation to access leisure space, especially haptic sense, which can be an effective design strategy to satisfy visitors.

This study aimed to investigate whether inhaling the aroma of essential oils could alleviate physiological stress responses and mimic the effects of forest therapy in urban settings. Briefly, 31 participants underwent stress index assessments for two days and inhaled the selected plant essential oils. The effects of this treatment on physiological responses were determined through electroencephalogram (EEG) and heart rate variability (HRV) measurements taken before and after inhaling the aroma of essential oils, extracting results for low frequency (LF) and high frequency (HF) components of HRV, as well as 𝜃 and 𝛼 brainwave activities. The results indicated that lavender oil did not yield significant differences, whereas pine, chamomile, and cypress oils exhibited significant differences in effects. Overall, stress relief was associated with enhanced 𝜃 and 𝛼 brainwave activities, a decrease in the LF component and an increase in the HF component of HRV. Among the essential oils studied, pine oil was the most effective. These findings underscore the potential of plant essential oils in replicating the therapeutic benefits of forest therapy, even in urban environments. Further investigations into their utilization are warranted to better understand and harness their therapeutic potential.
