Sound Art (Sonic Art) is a branch of contemporary art that has been practiced dominantly in Europe and the Americas since the mid-20th century; and in Korea, it tends to be regarded as a multiple art field or as a subgenre of contemporary music or media art. Since the 2000s, some leading universities in North America and Europe have been opened sound art majors, producing talented people who specialize in this field or work as practical artists, yet it is still considered a non-mainstream art field. It is difficult to find schools that have opened sound arts as their major program in domestic universities. Along with the introduction of a liberal arts curriculum model and teaching methods used in the <Sound Art of Modern Society> course operated in a four-year university in South Korea, this paper discusses the possibility of using sound art as a main subject in liberal arts learning in higher education as a creative fusion liberal arts subject.

When shaving, it is easy to suffer shaving burns, that is, facial burn irritation during shaving. The reason is that the razor blade irritates the skin. The current solution is to make the razor sharper and use a razor with a blade heating function. Although these ways can increase the comfort of shaving, they will also greatly increase shaving costs. This paper proposes using a hairdryer to massage the skin before shaving to reduce skin irritation during shaving. This is a simple, practical and low-cost method. The hair dryer's heat, sound, and wind energy have a massage effect, and they can make shaving easier and more comfortable. For analyzing shaving effect, two evaluation methods are used, which are sound spectrum analysis and mos. The sound spectrum analysis is used to analyze the working status of the razor objectively. The MOS test can reflect the subjective feelings of the subject on the shaving's comfort. The results show that the hairdryer thermal vibration massage can make the beard easier to cut, thereby reducing the irritation of the razor to the skin and improving shaving comfort.

This paper examines the historical meaning and value of sound art curating as a key type of interdisciplinary and convergence art practice that has been unfolding since the mid-20th century. Accordingly, this paper summarizes the developmental process from the beginning of 'sound art' to the present, but examines the context of visual art in which the material 'sound' functioned in chronological order, and focuses on curating cases of major sound art exhibitions. The purpose of this study is to analyze the impact and contemporary significance of the provided aesthetic experience. To this end, the text is divided into three sections and developed. The first section recognizes that the late 19th century futurist and Dadaist sound poetry, followed by Marcel Duchamp's 1913 attempt to combine musical score with visual art, had a profound influence on the visual music of avant-garde composer John Cage. This explains why this background caused the emergence of exhibitions dealing with 'sound' as a new medium. The second section explains that in the 1970s, sound as an artistic medium played a role in reflecting the critical relationship with the exhibition space dominated by visuality. In the third section, we analyze the curatorial methodology that allows the audience to experience sound as if it were a visual object within the organization of the exhibition hall from the 1980s to the present. Through this process, this paper critically treats the historical practice of customizing the perceptual structure in the exhibition hall, and considers the meaningful methodology of sound art curating considering the role of sound full of vitality in the contemporary art scene.

This paper considers the structure and meaning of the folktale accompaniment of the sound of UlsanSoeburisoree. The review process examined the meaning of each structure of the UlsanSoeburisoree in the preparation process while preparing the main elements of the structural features along with the historical background of the structure. UlsanSoeburisoree is Poongcheol ritual ceremony which means prayer ceremony for the production of iron. The sound of UlsanSoeburisoree is 1-Gilnori 2-Gosa 3-The sound of blowing smelting process 4-The sound of process of iron smelting 5-The sound of tabooline 6-The sound of blowing smelting process 7-The sound of blowing matches 8-The After-party. This structure is in line with the structure of folk play called Gilnory-Gosa-Performance-After-party. This is similar to the basic structure of folk beliefs Cheongsin(請神)-Osin(娛神)-Songsin(送神). Thus, the sound of UlsanSoeburisoree was formulated in a sequential parallel structure. The sound of UlsanSoeburisoree resemble the sacrifice of heaven ceremony since the time of the SamHan dynasty. The sound of the birth of life by physical sacrifice also plays the role of the song of creation of new life. The sound of UlsanSoeburisoree can be seen not only in Korea 's folk culture but also in folk culture of GyeongnamDo area. There are many festivals to pray for the abundance of life for UlsanSoeburisoree. Soil plays an absolute role in the process of producing iron. For those who soak it, the earth is a religious object. Among the folk tales handed down in the Yeongnam area, there are a lot of performances that are passed down through the blending of the people 's affection to overcome the harshness of life. In the case of the sound of UlsanSoeburisoree, it can be said that it was made and mixed with the wind that wanted to go beyond the harshness of life and the spirit of art.

Recently, on account of stress relief and settlement of a healthy drinking culture, many people are visiting a song practice room. In case of such song practice room, since the mechanical voice through a loud accompaniment-music and microphone is on using, there has made a very loud noise, and it influences a lot to the adjacent other space and song practice room booth. Consequently, from the designing stage an efficient measures for soundproof and sound-insulation should be arranged. However, as most of the song practice room wall-bodies that already built up or under construction step were constructed merely with consideration on an interior-wise factor only, it is suffering at the soundproof and sound-insulation. Reflecting such viewpoint, this Study has measured Sound Transmission Loss on the subject for the song practice room wall-body recently built up, and based on the actually measured data, by practice of comparison?analysis on it using various evaluation methods, would intends to present a fundamental material for establishment an efficient sound-insulation measure.

In this study, we tried to reveal the state of stillness of Cho Ji-Hoon's poem "Silent Night 1" as a healing modifier. The language of poem is synaptically linked to the calmness emotion of the human body, seeking a principle that leads to a state of healing. Therefore, this study was carried out for the purpose of applying the principle to literary therapy program. The silent signal embedded in the poem is encoded into the signals of the sound as it is synapsed to the human body. Encoding of auditory nerves by poem lines is like a Morse code that word and word leave in the human body. The action potential of the auditory nerve is further activated by the potential difference between the word and the word represented by the neural network, such as a Morse code, which is accessed to the human body by such a path. There is worked as amplified potential difference between the words perceived by a sound which is synapsed to the human body and by a silence which is synapsed to the human body. The phenomenon of the words approaching the human body and setting the absence of sound and amplifying the sound is because the words amplifies the Morse codes in the human neural network. At this time, the signals overlap each other. Thereby this poem is increasing the amplitude of the sound. This overlapping of auditory signals appears and amplifies the catharsis. If this Cho Ji-Hoon Poem's principle is applied to literary therapy program in the future, more effective treatment will be done.
