This paper investigates the possibility of exploiting haptic force-feedback technology for interacting with Nanta music. We use VR technologies including touch processing technologies and haptic devices to offer touch of cylinder objects and cup object to users. Haptic device is used to implement touch model in VR space. Matlab/Simulink and proSENCE Virtual Touch Toolbox of Handshake Inc. for experiment, are used as programing tools. Function needed to describe the movement of x, y, and z axis respectively are applied to delineate the natural movement of water in cup object modeled with 3D. A certain amount of water in cup object has the difference of sounds. In experiment, to perceive the appearance of 3D object by touch and to feel the tactile by touch are conducted with the effect of sound on Haptic perception. We also verify that it is possible to develop games or contents in VR space by using point.

Topophilia refers to emotional bonding such as attachment to or nostalgia for one's home town, which is remembered or imagined as a beautiful and happy paradise experienced in youth. The time spent in one's home town may have been short, but the associated memories of it are strong and enduring. These can later act as a strong motivator to learn if the correlated emotions are positive. According to archival research conducted on Jooyoung Chung's life, his home town and the things found therein, such as cows, were the principal objects of his topophilia, and later became the driving forces behind his success story. The same applies to Dvorak. Dvorak sublimated his nostalgia for his home town by composing a piece of music on hearing the sound of a train. We can discover diverse rhythms in nature such as sunrises and sunsets, the changing seasons, and even our heart beat. If a melody is added to the rhythm, it transforms into art. And if we seek harmony and principles, it becomes science. In this study, Jeonbuk's nature, places, food, and arts, as represented in its educational resources, are analysed for their ability to give rise to topophilia. To gain some experience of this feeling we recommend that you visit the Jeonju Hanok Village, the value of Gochujang, reverse icespike on Mai Mountain or enjoy the works of the painter Book Choi.

Environmental problems can be dealt in the diverse areas such as engineering, public administration, and law. However, the education on environmental preservation is conceived as the fundamental solution for environmental problems, because the education can make the person of action. Specifically, building the attitude and habit of environmental preservation through environmental education is the effective and efficient way of environmental preservation. This research was conducted to develop an education system that is designed to build students' attitude and habit of environmental preservation through acquiring knowledge and functions of natural environment. The proposed system supports diverse learning activities such as writing, drawing, listening natural sounds and music, and problem solving. The system is technically designed on the Web to promote students' creativity and autonomy, and also are theoretically based on constructivism to build the will of environmental preservation. Moreover, the proposed Web-based system includes diverse functions such as classes, material resources, environmental quiz pool, environmental work gallery, which motivate students' learning activities. Therefore the proposed Web-based system is expected as an effective tool to achieve the goals of environmental education such as acquiring environmental knowledge and functions, building attitude of environmental preservation, and participating in the environmental preservation activities.

This study seeks to identify the effects of light pollution and environmental factors on Great Tits(Parus major) bird's chirping at dawn. For this research, the campus of Sanji University, Wonju, South Korea was selected as the area with light pollution and the western forest of the Chiaksan National Park was chosen as the natural area herein. The Recording period was between March 26th and May 30th, 2014. As a result of analyzing the chirping time according to light pollution, it was found that the light pollution area clearly showed earlier chirping time than the natural area (p<0.05). Great Tits(P. major) normally start their first chirping before sunrise and in most of the days under investigation of this research, those in Sanji University started to chirp earlier. This faster chirping time seems to improve the chance for the female birds to mate with immature males thus, baby birds hatch earlier than the appropriate breeding season and results in the lack of feed resources. The correlation between Great Tits'(P. major) dawn chirping and environmental factors were investigated herein including the time of sunrise, civil twilight, navigation twilight, astronomical twilight, average temperature, highest temperature, lowest temperature, time of moonrise and cloudiness. The first chirping time of wild birds in the day was found to have correlations with all of the environmental factors excluding the time of moonrise and cloudiness. Great Tits(P. major) started their first chirping before sunrise when the day started to break around civil twilight. Along with the earlier sunrise and higher air temperature, their dawn chirping time was also quickened. The time of moonrise and cloudiness did not show a correlation and further follow-up studies will be necessary in this regard.

This study was conducted to provide basic data for realistic applicable changes of sirens by identifying the stress due to the currently used sirens and the need for improving siren. The data was collected from an online survey of 267 subjects who voluntarily agreed to join this study from August 2019 to September, 2019. A structured questionnaire was used as a research tool. The results were analyzed by means and standard deviations, percentages and frequency analysis, and independent t-tests using SPSS. For the current workplace emergency siren type, it is believed that the number of hybrid formats was 143, the most negative opinion of the siren is high at 132, so periodic replacement is needed. For contextual stresses, the highest was 4.35 ± 0.94, when the siren was heard during bedtime. In the stress during sleep, which was based on the daily mean number of movements,, a statistically significant difference was shown between groups of 9 or more movements and below 9 movements (p <0.05). The type of siren paramedics wanted was 'soft music' and 'sound of nature'. More than half of 168 people (62.9%) wanted to replace the current siren, and 163 (91.6%) wanted that periodically within 24 months. Therefore, it is necessary to improve the siren.

Stress has become one of the largest health risk to shorten the life time of health. Accordingly, in order to increase the life time of health, stress relief can be very important. Many social expenses and economic commitment have been inputted for this purpose, but their effectiveness compared to the current situation is not very high. In this paper, we carried out an identification work of rain sound which is similar to the white noise that can stabilize the body and mind of the person by analyzing the variations of 3rd formant frequency bandwidth. Also, for relieving stress, the sounds of rain that is easily accessible at a relatively among the sounds of nature instead of consuming a lot of money and time were selected for solving these problems. In addition, we identified the effectiveness of the stress relief about the sound of rain and research on whether there is a difference between men and women in their 20's or not was performed. Finally, we discussed the personal - adjusted rain making to maximize the effectiveness of stress relief.
