In this study the author analysed impact of image of regional festival on satisfaction of tourists and their intention for revisit through an example of firefly festival in Youngyang-kun. Current Firefly Festival of Youngyang is its fifth since its beginning. Unlike festivals in other areas it is held during daytime and nighttime respectively. In it natural environment and ecosystem in Youngyang area are highlighted and it is unique in the sense that such festival is performed with live insects. Festival is organized with various sights to see including experiencing flying fireflies in nighttime and making insects etc. In this study the author analysed impact of image of regional festival on satisfaction of tourists and their intention for revisit. In this connection this author chose 20 items in connection with image of regional festival. Then I carried out analysis on various factors in connection with tourists as appeared in regional festival. I performed analysis on diversity, experience, convenience, conveyance of content of festival and its creativity as factors constituting satisfaction of tourists in connection with image of regional festival. Result of analysis undertaken in this study revealed that image of regional festival and satisfaction of tourists who experienced festivals served to their expressing intention for revisiting. For inducing tourists intention for revisiting image of regional festival, conveyance of diverse information, diversity of program of the festival, new experience, sense of expectation are important. Therefore this is need for development of environment and ecosystem friendly programs and it should be developed as a consistent environment friendly festival rather on temporary touch- and-go event.

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.

Silica and polymethylsilsesquioxane (PMSQ) are silicone powders widely used as cosmetics. We synthesized silica-PMSQ composites via sol-gel method using tetraethoxysilane (TEOS) and methyltrimethoxysilane (MTMS) as precursors of silica and PMSQ, respectively. Shape of the composites was controlled by varying the ratios of TEOS and MTMS, which were used as silane monomers. Silica-PMSQ composites showed three different shapes, which were sphere-shape, raspberry- shape, and donut- shape. All of them had soft touch, easy water dispersion, and soft focus effect in common. However, each shape showed some differences in sense of use, adhesion, and strength of the soft focus effect. Raspberry-shape composite had the strongest soft focus effect, donut-shape one had the strongest adhesion, and sphere-shape one had the best in softness. Thus, it is concluded that by varying the ratios of TEOS and MTMS silica-PMSQ composites could be easily synthesized into different shapes, providing various functions. This method can be applied to manufacture functional cosmetics.

In this paper, we propose a haptic display system that can convert Braille and tactual map(braille map) to tactile information recognizable through sense of touch almost in real-time. The proposed system consists of a haptic display hardware device, which actually delivers tactile signal to visually impaired people, and a device control software program, which converts Braille and tactile information to tactile signal and transfers it to the hardware device. Experimental evaluations of the proposed system were performed with 10 visually impaired persons. Experimental results show that the proposed system can provide similar Braille recognition rate and speed to those of existing Braille information devices. In addition, the proposed system converts tactile information to tactile signal under maximum 1.1 seconds, so that it can provide graphic information in almost real-time which is not possible with existing tactile devices, such as Braille printer.

Immersive contents is content that provides a realistic experience by maximizing the user's five senses, and includes virtual reality, augmented reality, and mixed reality. In order to provide a sense of reality to users in immersive content, it is necessary to provide realistic visual images, hearing, and touch. However, due to the rapid change in the environment for developing immersive content, experts in training human resources are having difficulties in designing the curriculum. In this study, we propose a series of educational courses that use drones to acquire and process real-world measurement data and apply the derived data to VR, AR, and MR to help experts in training immersive content develop talent. The design of training process composes through demand survey and analysis of companies, students, and local communities. This study can be a useful resource for education experts who want to train immersive contents manpower.

The haptic sense is one of the five human senses that deeply affects cognitive development and everyday lives of children and adults. Recently, researchers and developers have started active discussions and research on haptic technologies. The purpose of this paper is to explain the role of haptics in learning, review studies that have attempted to use haptic technologies to teach students, and discuss how these technologies can be applied in special education context. National and international databases were searched and analyzed using meta-analysis methods. The few studies that have been completed so far are heavily focused on math and science learning. However, haptic technology has great potentials for children with disabilities who can benefit from extra assistance from these devices in wide areas of curriculum including math, science, music, art, history, and so on.

Osteosarcomas are highly malignant bone tumors which commonly affect metaphyseal portions of long bones and those of the skull are distinctly rare as primary neoplasm. We report a case of recurrent osteosarcoma originated from the skull base which destructed sphenoid bone in two months. The CT and MR images of 28 years old man with headache, dizziness, and loss of touch sense in right buccal area showed 3-cm sized homogenously well-enhancing mass with internal small cystic portions. Craniotomy and mass excision was done and chemotherapy was combined for 1 month. After about 2 month, follow up MR images showed larger recurrent mass in original site and confirmed as the same osteosarcoma after 2nd operation.

This paper presents an interactive wind system that generates artificial winds in a virtual reality (VR) environment according to online user inputs from a steering wheel and an acceleration pedal. Our system is composed of a head-mounted display (HMD) and three electric fans to make the user sense touch from the winds blowing from three different directions in a racing car VR application. To evaluate the effectiveness of the winds for reducing VR cybersickness, we employ the simulator sickness questionnaire (SSQ), which is one of the most common measures for cybersickness. We conducted experiments on 13 subjects for the racing car contents first with the winds and then without them or vice versa. Our results showed that the VR contents with the artificial winds clearly reduce cybersickness while providing a positive user experience.

Five Plus One' is a result of visual expressions on five senses such as the sense of sight, hearing, smell, taste, and touch. Although I searched for the data on five senses, there were only information which was quoted in various languages and scientific bases, and also most of the books written were far from artistic expressions including visual pleasure and emotional expressions. In addition, most materials were mainly textbooks for children's intellectual development, academic papers, and medical publications. Therefore, I made this book that makes us to communicate about five senses and an inspiration even though we have a problem to read writings in both Korean and English. I arranged visual elements using illustrations and typography in various ways based on the scientific evidence.

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.
