Kinect sensors have the ability to recognize the behavior and voice of the user. Due to its low-cost and high accessibility, Kinect sensors have been used in various fields, including healthcare, education and so on. In this paper, we propose to use Kinect in piano education. Specifically, the proposed method first recognizes the coordinate values of user's posture, compares them with coordinate values of teacher's posture and provide real-time feedbacks to the user. This enables user to keep the correct posture even when he is learning piano without a teacher. However, since the piano education is a long process, it is difficult to achieve the correct posture as a teacher immediately. Thus, we propose a user-oriented method to measure the error tolerance rate. The proposed method is the first feedback based piano education system that uses Kinect sensors.

Most of music-transcription systems that have been commercialized operate based on audio information. However, these conventional systems have disadvantages of environmental dependency, equipment dependency, and time latency. This paper studied a vision-based music-transcription system that utilizes video information rather than audio information, which is a traditional method of music-transcription programs. Computer vision technology is widely used as a field for analyzing and applying information from equipment such as cameras. In this paper, we created a program to generate MIDI file which is electronic music notes by using smart-phone cameras to record the play of piano.

As parents are interested in music education for infants in these days, they require systems to help these infants to actively play music. In this paper, we propose a keyboard solo system using a real time hand recognition method. In order to enable the infants to use the system easily, the proposed system plays some sounds whenever the infants move their fingers on a paper piano. For the purpose of minimizing cost to play music, the proposed system utilizes a general PC with only a paper piano, a web camera, and a speaker. With the aim of precisely and efficiently recognizing both a hand and each key on keyboard, the proposed system divides a recognition step into a hand recognition step and a keyboard recognition step. Also, the hand recognition step considers only skin color, and the keyboard recognition step considers only black and white without other colors.

Ear training is said to be the ability to measure sound either in terms of musical scale or cord by listening to music acoustically. This is the most basic subject and the most practical technique in any music genre; also, the most crucial factor for individuals who are studying music. Ear training is an important skill to develop when learning to play the piano, or learning any kind of musical instrument. It is also the key factor in a successful music education. Everyone can develop their musical ability if ear training is provided during childhood. The aim of this study is to develop an ear training system whereby beginners or children can learn music with ease in terms of computer access which is part of their daily life. This system is devised so that children can practice ear training easily. This system is also beneficial to others who plan to major in music.

The article considers one of the areas of development of artificial intelligence where there is the development of computer intelligent systems capable of performing functions traditionally considered intelligent - language comprehension, inference, use of accumulated knowledge, learning, pattern recognition, as well as learn and explain their decisions. It is found that informational intellectual systems are promising in their development. The article is devoted to intelligent information systems and technologies in educational activities, ie issues of organization, design, development and application of systems designed for information processing, which are based on the use of artificial intelligence methods.

Monomeric rhodium and iridium diimine complexes $Cp^*M(HNRNH)(Cp^*$ = 1,2,3,4,5-pentamethylcyclopentadienyl : (M=lr; R=o-$C_6H_4 (1a), 4,5-(CH_3)_2-C_6H_2-1,2 (1b), 4,5-(Cl)_2-C_6H_2-1,2$ (1c), NCC=CCN-1,2 (1d): M=Rh; R=NCC=CCN-1,2 (1e)) have been synthesized from $[CP^*MCl_2]_2$ and 2 equiv. of diamine in the presence of $NEt_3$. The Crystal structure of 1a was determined by X-ray diffraction method : 1a was crystallized in the monoclinic system, space group $P2_{1/c}$, with lattice constants a=9.543 (1) ${\AA}$, b=16.286 (1) ${\AA}$, c=10.068 (1) ${\AA}$ and ${\beta}$=99.25 (1), with Z= 4. Least-squares refinement of the structure led to R factor of 0.049. The coordination sphere of rhodium and iridium can be described as a 2-legged piano-stool. All complexes are highly colored. Electrochemical studies show that 1d and 1e display quasi-reversible reduction and 1a-1c display irreversible reductions, suggesting that the acceptor orbital might be localized on the diimine ring.

본 연구는 립모션을 통해 피아노교육을 제공함과 동시에 알맞은 운지법을 제안한다. 기존의 피아노 교육 프로그램은 운지법을 제공하지 않아 피아노를 한 번도 접해보지 못한 사람들은 제대로 된 기초를 배우지 못했다. 따라서 본 논문에서는 알맞은 운지법을 제안하고, 립모션과 컴퓨터가 실행되는 환경 어디에서든 프로그램을 실행 할 수 있도록 하였다.

These days there are so many music school graduates. There are also many private music education institutions. Therefor the competition in music private education market very tight. In old days people working in education music market had made big money and many parents wanted their girls and boys to learn piano and other musical instruments. However recently birth ratio in Korea has been dramatically dropped and not many parents wants their kids to learn musical instruments because of economic depression and negative music market. Eventually the size of the music education market is decreased dramatically and the competition in music education market is very hot. Therefor without the upgraded management system it is hard to expect over performance in music education market aspects. The purpose of this study was to find out what are the main factors that affect on business performance of the music education institutions. The main areas that researched in this study were success factors, reason of the start-up, and factors of management success. The research was conducted on the owners of the music education institutions. The factors that affect on the outcome of the business performance were diverse. Therefore the management of music education institutions also need the systematical analysis on the location, environmental factors, people nearby areas, differentiated market strategy and other analysis the same as corporate and business management.
