It is said that the goal of the design of good acoustical environment is at first the reduction of undesirable sounds, and in addition the introduction of desirable sounds by which our minds are soothed. The task of creating the desirable sounds leads to the realization of a comfortable acoustic environment and the design of soundscape. It may be an important starting point of soundscape design to select suitable sounds for the target spaces, because each space has a different surrounding condition and requires a special ambient sound. This paper aims to survey preference of the environmental sounds suitable for the public spaces in urban areas such as parks, bus terminals. 35 kinds of natural sounds are rated by 26 pairs of adjectives. The results of psycho-acoustic experiments are as follows. 1. The proper adjectives for expressing the environmental sounds are classified into 6 groups of comfort, pleasure, fullness, variety, distinctness, naturalness. 2. Bird singing, murmuring of a stream, artificial sounds, singing of insects and animals are the affirmative order of preference. 3. Green musics consisted of music and natural sounds are preferred to the pure natural sounds. 4. Sound level relative to background noise causes various preferences to natural sounds in public spaces.

The art museum plays a role as a cultural space that can solve the cultural desire of people and see a good art works. It is in exhibition space that they personally exchange the feeling between an art work and a viewer in art museum. The types and works - a fiber, a photo, an establishment that needs many places, devices, a video art, and an action art called "performance", cultural art - are shown in small art museum. Moreover, exhibition spaces are modified into the space of another art activities like dancing, music concerts in small art museum because it has no profit space for diverse art activities. And the exhibition the characters of the exhibition space in small art museum. So, it needs to change the characters of the exhibition space in small art museum. Under these background, this stud\ulcorner surveys and analyzes the exhibits, the organization methods, the modified conditions, and the scale of the existing exhibitional space in small art museum. Therefore, the goal of this study is to suggest the composition of the exhibition space unit considering the function and the multifunction in minimum art museum and small art museum.

Andree Potman is one of the few French female interior designers who has successfully extended her design territory beyond France into a more global context. Unlike other interior designers Potman has a very unique and eclectic background. She has studied music, worked as a journalist, talented in redeveloping designs that were unknown at that time such as design's of Eileen Gray, Mallet-Stevenson, and many more. Starting her career as an interior designer we can see her designs not only in France but also in many other countries such as America, Japan, and Germany. However her name is not that familiar to the designers in Korea. Therefore the current study focuses on the introduction and understanding of Potman's designs in regards to the relationship between interior space and objets that have made her designs so called 'Potman Style'. In order to accomplish the objective the researcher first studied means and use of ejects in interior space and next examined characteristics of Potman's designs including lighting fixtures, products, furnitures, and Interior designs. Finally, by using constant comparative analysis four categories (esthetics of emptiness, repetition of geometric forms, contrast in style, and focus with lighting) of design methods are revealed as the characteristics of interior elements as objects in Andree Potman's interior designs.

In recent years, various virtual reality contents have been explosively developed, and the 'chance operation' in previous studies was mentioned. This study tries to implement the Step Sequencer in the virtual reality. Through the theoretical background analysis and case studies of virtual reality, three major experiential values such as Value of Overcoming Constraints, Value of Strengthening Experience, and Value of Creating New Experience were induced. A convergencestep sequencer with the presence and immersion elements was developed and presented so that the music contents divided into 4 areas can be understood easily controlled more conveniently while keeping the identity of the step sequencer. It is expected that various convergence VR contentscan be developed in the future studies.

This study presents a new fashion wearable product, a classical music stage costume design, using an Arduino LilyPad that can control light-emitting diodes(LEDs) and a sound sensor that can set an environmental range of LED light. As a theoretical background, LED fashion design research and stage costume design research status were reviewed, and Arduino LilyPads, sensors, LEDs, and batteries required for LED stage costume production were investigated. Based on prior research, the LED stage costume design for the soprano stage was presented in a three-step process of design planning, development, and production, and an actual prototype was produced. This process produced meaningful information and materials for making clothes with the added function of a wearable computer. In particular, fashion designers or fashion majors can easily access the Arduino LillyPad and use not only LEDs, but other light emitting materials. It is expected that it will be used as a basic material for the use of the Arduino LillyPad that can develop new creations that have been utilized.

This paper, is in the focus of the fact that was popular in the Joseon Dynasty, was clearly private background and fashionable aspects of its creation. In Section 2, as the background of the epidemic of of the Joseon Dynasty, and was derived creative situation of . is the "left Order live music" relationship center rather, was that it was created by the Academy belongs is highlighted "Hanlin year". As a result, collapses the relationship between the order raw Korea early left, in conjunction with the boast to debauchery and evaluated surface Shinyoung of successor Geibun of this academy, be epidemic in the Joseon Dynasty it is the could be. In Chapter 3, and two to the original, it was examined the epidemic surface of of the Joseon Dynasty. The epidemic of surface, in the conventional research and are relatively detailed, but in this paper, while accommodating the existing research results, of consideration "Hanlim feast" has led to Geibun of Korea "immune new Feast" was observed a trend surface is placed around the fact. As a result, , the Joseon is that it has been singing on the occasion official four-kan and Geibun center, first Nara are exempt new feast bonds back to the four Hall again in Geibun, usually it can be seen that it is spread in the Scholar-official and gisaeng's. Lower limit has been singing can be up to around the late 17th century it has been speculated through the time of Gimumanjun.

Recently, Many 3D augmented reality games that provide strengthened immersive have appeared in the 3D game environment. In this article, we describe a barehanded interaction method based on human hand gestures for augmented reality games. First, feature points are extracted from input video streams. Point features are tracked and motion of moving objects are computed. The shape of the motion trajectories are used to determine whether the motion is intended gestures. A long smooth trajectory toward one of virtual objects or menus is classified as an intended gesture and the corresponding action is invoked. To prove the validity of the proposed method, we implemented two simple augmented reality applications: a gesture-based music player and a virtual basketball game. In the music player, several menu icons are displayed on the top of the screen and an user can activate a menu by hand gestures. In the virtual basketball game, a virtual ball is bouncing in a virtual cube space and the real video stream is shown in the background. An user can hit the virtual ball with his hand gestures. From the experiments for three untrained users, it is shown that the accuracy of menu activation according to the intended gestures is 94% for normal speed gestures and 84% for fast and abrupt gestures.

Background and Objectives : Many studies have described and analyzed singer's formant and it has been shown that the epilaryngeal tube in the human airway is responsible for vocal ring, or the singer's formant. A similar phenomenon produced by trained singers in their speech led some authors to examine the speaker's ring. This study was designed to analyze the speaking voice of the singers and speaker's ring. Baterials and Methods : Ten tenors, fifteen baritones, fifteen sopranos and ten mezzo sopranos attending the music college, department of vocal music were chosen for this study. Fifteen male and fifteen female untrained normal speakers were chosen for control group. Each subject was asked to produce a sample of a sustained spoken vowel /ah/ sound for at least five seconds and read sentence 'Kaeul'. The sound data was analyzed using the Fast Fourier Transform(FFT) - based power spectrum, Long term average(LTA) power spectrum using the FFT algorithm of the Computerized Speech Lab(CSL, Kay elemetrics, Model 4300B, USA). Statistical analysis was performed using the Mann-Whitney test of the Statistical Package for Social Sciences(SPSS). Results : For LTA Power spectrum of/ah/ sound, a significant increase was seen in the 2,500-3,500Hz region(p<0.01) in four trained singer group compared with untrained speaker group, and a significant increase in the 9,000-10,000Hz region(p<0.01) in soparano group. Similarly, in sentence 'Kaeul', there was a significant increase in energy in the tenor, baritone, mezzo soprano group compared with the untrained speaker group in the 2,500-3,500Hz region(p<0.01), and a significant increase in all frequency region(p<0.01) in the soprano group. Conclusions : The LTA power spectrum suggests that trained singers group show more energy concentration in the 'singer's formant' region in the speaking voice, and authors believe this region to be the 'speaker's ring'. Further research is needed on the effect of singing training on the resonance of the speaking voice.

This study focuses on the importance of macro socio-economic factors to explain the successes of Hallyu(Korean Wave). Studies of Hallyu have mainly discussed the contents of Hallyu products, emphasizing the excellence of Korean culture or cultural similarities in the East Asia. Analyzing cultural industrial factors, the study purports to contribute to more comprehensive explanations of Hallyu. To do so, the study analyzes the Japanese case, because Japan is considered as society where Hallyu is most institutionalized. The study suggests the importance of cultural exchanges between Korea and Japan as the background factors for Hallyu's success in Japan. In addition, the study shows the interactions of 'push factors' in Korea and 'pull factors' from Japan. As for push factors in Korea, this paper suggests the decline of music records(CD and DVD) industry and growing competition in broadcasting industry in Korea. Regarding the pull factors from Japan, robust music industry and changing broadcasting system are discussed. Although this paper try to suggest as many evidences as possible, the macro data suggested are not fully comprehensive enough to explain the importance of cultural industrial factors. In addition, micro-level analyses on the interactions among people who are working in the cultural industries are also necessary, and thus remained for the future studies.

Background and Objectives : It has been shown that the epilaryngeal tube in the human airway is responsible for vocal ring, or the singer's formant. In previous study, authors showed that in trained tenors, besides the conventional singer's formant in the region of ,5500Hz, another energy peak was observed in the region of 8,000Hz. This peak was interpreted as the second resonance of the epilarynx tube. Singers in other voice categories who produce vocal ring are assumed to have the same peak, but no measurements have as yet been made. Materials and Methods : Fifteen tenors, fourteen baritones, seven sopranos and five mezzo sopranos attending the music college, department of vocal music who could reliably produce the head and chest registers were chosen for this study. Each subject was asked to produce an/ah/sound for at least three seconds for the head register sound(tenors ; G4, barions ; E4 sopranos ; F5 and mezzosopranos ; C5) and for the chest register sound (tenors ; C3, baritones ; D3, sopranos ; D4 and Mezzosoprano ; A3). The sound data was analyzed using the Fast Fourier Transform (FFT)-based power spectrum, Long term average(LTA) power spectrum using the FFT algorithm of the Computerized Speech Lab (CSL, Kay elemetrics, Model 4300B, USA). Statistical analysis was performed using the Mann-Whitney test of the Statistical Package for Social sciences(SPSS). Results : For head register sounds, a significant increase was seen in the 2,200-3,400Hz region(p<0.05) and the Similar to the head register sounds, there was a significant increase in energy in the four trained singer group compared with the untrained group in the 2,200-3,100Hz region(p<0.05), the 7,800-8,400Hz region(p<0.05) for the chest register sounds. Conclusions : When good vocal production was made for the head and chest registers, an energy peak was observed near 2,500Hz, a frequency already known as the "singer's formant', in all subjects in the study group. Another region of increased energy was observed around 8,000Hz that had not been noticed previously. The authors believe this region to be the second singer's formant.
