In this study, through the capstone design project, an IoT based piano training system was developed after identifying problems in piano learning. The piano training system recognizes sheet music through image processing technology and checks whether the correct keyboard is struck through FFT transformation during piano practicing. By providing a visual effect and score display function using a rhythm game, it was possible to arouse interest in boring piano practice and increase the effect of piano learning.

본 연구는 기후변화에 따른 돌발홍수 및 집중호우 대비 댐 및 저수지의 보조 여수로로서 국내 최초로 적용되는 Piano key weir에 대한 수리모형실험 연구이다. 최근 기후변화에 따른 이상기후로 국지성 집중호우 및 돌발홍수가 빈번히 발생하고, 댐 설계홍수량의 설계기준 200년 빈도 홍수량에서 가능최대홍수량(Probably Maximum Flood)으로 변경됨에 따라 과거 건설된 대부분의 댐 및 저수지들이 현재의 설계기준을 만족하지 못하고 있는 실정이다. 상기 이유로 규모가 작은 저수용량 100만톤 이상의 댐들에 대해서도 비상대처계획(EAP) 수립을 의무화하고 있으나 홍수예방을 위한 적극적인 대책 수립 및 예산지원은 미미한 수준이다. 치수능력증대를 위한 구조적인 보강대책으로 댐 증고, 보조여수로 신설, 여수로 확장, 상류에 홍수조절용 댐 신설 등의 방안이 적용되고 있다. 본 연구의 대상지인 불갑저수지에서는 치수능력확대사업의 일환으로 Piano key weir와 수문 2련을 복합적으로 운영하는 보조여수로를 건설하는 것을 계획하였다. Piano key weir는 국내에서는 프랑스, 벨기에, 베트남 등에서는 실제 많은 적용사례를 확인할 수 있지만, 국내에서는 처음으로 도입되는 여수로 형식으로 레버런스 웨어와 같이 월류언의 길이를 길게 연장함으로서 월류 수심이 낮은 경우에 일반적인 웨어 형식에 비해 많은 유량을 통수할 수 있는 장점을 가지고 있다. 본 연구에서는 불갑저수지에 신설되는 Piano key weir 형식의 보조여수로에 대한 수리모형실험을 수행하여 Piano key weir의 수위별 방류량, 접근흐름, 월류 유황 등에 대해 검토하였다. 검토결과, PMF홍수량에 대해 충분한 방류가 가능함을 확인하였으며, 접근흐름, 월류 유황이 매우 안정적인 것으로 평가되었다.

Our purpose was to know whether photo-induced adequate nitric oxide (PIANO)-mediated relaxation of rat aorta is involved in cyclic GMP increment as well as inhibition of phosphatidylinositide hydrolysis due to phenylephrine (PE). Isometric tension was measured in vitro in response to either agents that modulate NO production or release NO by photolysis of photosensitizing agents in rat aorta that had been contracted with PE submaximally. PIANO-mediated relaxation was accompanied by increment of cyclic GMP, which was dependent on the intensity and duration of light exposure and concentration of photosensitizers. Phosphatidylinositide (PI) turnover augmented by PE was significantly inhibited by PIANO. These findings indiate that cGMP increment is responsible for PIANO-mediated relaxation and which may account for the inhibition of PI turnover due to ${\alpha}-adrenergic$ receptor stimulation.

Jane Campion's is a well-known film for a number of reasons, such as for being an Oscar winner, for having been helmed by an emerging director from New Zealand, and for having the reputation of being a feminist film. In this paper, the first scene of was chosen to examine the heroine Ada's language in terms of the gothic genre. Ada is a dumb woman who lives in the era of man's language. She represents the women's social position in the Victorian era but has her own and unique language for communicating with the outside world. The first scene of introduces Ada's own language, using her fingers. Her fingers speak for her all the time instead of her mouth, and there is someone who can understand what she wants to say when all others cannot. How the film depicts Ada's language and how the first scene well summarizes the film's core are examined herein.

Nonlinear weirs, such as labyrinth and piano key weirs, are suitable methods to handle increased flood flows that may be expected due to climate change. Although specific physical models are considered to be an effective way of investigating fluid flows, simply conducting physical model tests is insufficient to fully comprehend the hydraulic and discharge characteristics of non-linear weirs. In this study, computational fluid dynamics algorithms have been used extensively to investigate complex flow physics instead of relying on reduced scale models. The discharge capacity of the piano key weir and the rectangular labyrinth weir is compared using a three-dimensional numerical model, which is validated by the available experimental data. The results confirm that piano key weir is more efficient than the rectangular labyrinth weir for a wide range of head water ratios. By analyzing the contribution of discharge over inlet, outlet and sidewall crests, the factor that make the piano key weir superior to the rectangular weir is the sidewall discharge.

Piano is one of the most beloved instruments in the world and is used a lot for children to learn music because it is simple to play. As a result, various products for children, such as toy pianos, were released. However, there is a lack of piano skills for music education, such as how to play the piano or read the score. To solve this problem, in this paper, we propose a game-style educational piano using Arduino. It is expected to capture fun and education at a low price by scoring points by displaying the score on the LCD screen and pressing the keyboard according to the timing of playing the note.

Renzo Piano was first introduced to us when he got together with Richard Rogers and won the Grand Prize on Center George Pompidou Competition in Paris. Since then, he designed number of world renowned museum architecture such as Menil Collection & Museum, The Cy Twombly Gallery, Beyeler Foundation Museum, and most recently the New Pavilion of High Museum of Art. His museum design, in particular, showed very consistent feature which is differentiating the 'Served Space(exhibition area) and the Servant Space(service core or mechanical system area)'. In addition, the way he treats natural light as a special feature within his museum space was nicely done and it is remarkable both in design and engineering side; he always designed a very unique roof structure system to give life and to simulate emotion of light within the space. These are just a few points of his special design characteristics which differentiate him from the rest of the architect working today. While interested by works of Renzo Piano, we found that his work had very close relationship to Louis I. Kahn's design. Specially the way Renzo Piano differentiating serving and servant space and the way he treating natural light. Therefore, the purpose of study is focused on providing typology of museum exhibition organization as well as finding evidence of Louis I. Kahn's influence and concept he has shown in his museum projects through actual site visits and reference research. The method of research was as the following; first to find typology and its characteristics of exhibition space organization of all Renzo Piano's museum projects. Secondly to distinguish projects which show 'differentiated servant and served space'. As the result of this study, it was clear that Renzo Piano had influence of Louis I. Kahn on adopting 'Servant and Served Space' concept. But the research concluded with the facts to approve the uniqueness of Renzo Piane's design concept.

Thanks to the development of the Internet, people can easily access a vast amount of music. This brings attention to application systems such as a melody-based music search service or music recommendation service. Extracting melodies from music is a crucial process to provide such services. This paper introduces a novel algorithm that can extract melodies from piano music. Since piano can produce polyphonic music, we expect that by studying melody extraction from piano music, we can help extract melodies from general polyphonic music.

In Jane Campion's Stewart, Ada's husband, as like modern people, manifests the infinite lust of conquest. But Banes has a humanistic relation with the New Zealand's tribe and doesn't have a deep attachment of his own land. Stewart represents the ruling reason in that he disregards his wife's desire and acts only for his desire to possess and conquest. In contrast with him, in order to satisfy her desire of the piano and hold her own inner world in common, Banes proposes the extraordinary deal, that is to say, to exchange her piano and his land and to learn playing the piano from her. Like this Banes represents the caring reason in that he regards Ada's desire and cares her in according to her purpose and himself.

The recent growth of a digital music market induces increasing demands for music searching and recommendation services. In order to improve the performance of music-based application services, the process of extracting melodies from polyphonic music is essential. In this paper, we propose a method to extract melodies from piano solo music which is highly polyphonic and has a wide pitch range. We categorize piano music into three classes taking into account the characteristics of music, and extract melodies according to each class. The performance evaluation for the implemented system showed that our method works successfully on a variety of piano solo music.
