악기 연주는 장시간의 꾸준한 학습이 필요하다. 피아노나 기타와 같이 박자와 가락을 동시에 연주 할 수 있는 악기는 다양한 표현을 낼 수 있지만 그만큼 학습에 시간과 노력을 투자해야 한다. 본 논문은 악기 연주에 대한 새로운 인터페이스를 제안한다. 특히, 사용자가 악기 연주를 학습하는 것에 긴 시간과 많은 노력을 투입하지 않고, 전문 지식 없이도 중급 이상의 퍼포먼스를 낼 수 있도록 하는 것이 목표이다. 제안된 악기 인터페이스는 음악 코드를 선택하는 코드선택기와 실질적인 연주가 이루어지는 건반으로 구성되어있다. 코드선택기는 사용자가 코드를 선택하면 그에 해당하는 음들을 건반에 배치하며, 이후 진행할 수 있는 후보코드를 사용자에게 알려준다. 건반은 사용자의 연주를 미디메시지로 변환하여 출력한다. 이 두 장치는 사용자가 학습에 많은 어려움을 느끼는 가락을 만들고 진행하는 부분에 대해 좀더 쉬운 솔루션을 제공할 것으로 기대된다.

이 논문에서는 피아노 건반을 연주하거나 악보 위의 음을 누르는 방식의 새로운 멜로디 패스워드 인증기법을 제안한다. 등록단계에서 사용자는 피아노 건반을 치거나, 악보 위를 터치하는 방법을 통해 사용자의 멜로디를 생성하여 이를 암호로 설정한다. 인증단계에서는 등록한 멜로디를 다시 생성하면 암호가 해제된다. 이 기법은 암호공간의 확대를 통하여 안전성을 강화하고, 피아노를 연주하는 재미를 유발하여 인증방법의 친화성을 향상시킬 수 있다.

A simplified photoelectric apparatus producing graphic records of the free Achilles tendon reflex allowed us to study the reflex quantitatively in subjects with normal and abnormal thyroid function. In this study Achilles tendon reflex times were tested in 340 normal Korean persons, 89 hyperthyroid patients, 19 hypothyroid patients and 85 other thyroid disease patients who were euthyroid in thyroid function tests. In normal Korean persons, the Achilles tendon reflex time was delayed with increasing age and slower in female than in male. They showed good correlationship with various thyroid function tests which included ETR, $T_3RU,\;^{131}I$ thyroid uptake and serum TSH. Diagnostic accuracy of them was 71% in hyperthyroidism and 90% in hypothyroidism. Finally the serial measurements of them were very useful tests in evaluating the clinical coures of hyperthyroidism and hypothyroidism once treatment was begun.

In this paper, the remote care of medical beds with multiple body pressure sensors is described. Falling is one of the factors that seriously threaten the safety of patients and harm their health. In this study, a new bed was developed to overcome this. The bed system consists of a keyboard that can operate, a keyboard controller that manages the movement of the keyboard, a sensor that measures body pressure, a sensor controller that transmits and receives sensor values, a main controller that checks it and operates automatically or manually according to the algorithm, and a server that oversees all these information. The bed system checks the patient's location through a sensor and wirelessly alerts the server through the main controller when the patient determines that there is a risk of falling, so that the nurse or nurse can recognize the patient's dangerous condition. The server may receive state data transmitted from the wired/wireless terminal to monitor whether the bed system is operating normally. The controller of the keyboard operates a keyboard-type mechanism and automatically controls the prevention of bedsores connected by body pressure sensors to physically separate the area to which the patient's pressure is applied to prevent bedsores. The main controller checks the presence of the patient's bed and transmits it to the server. In conclusion, the proposed system can smart monitor the user's state and perform remote care.

아코디온은 키보드와 건반 그리고 공기주머니로 구성 되어 있는 악기로써 건반 악기의 특성과 화음을 위한 키보드 코드의 손가락 운영 기법이 요구되는 악기의 특성을 갖는다. 따라서, 연주를 자습하거나 독자적인 교습을 위한 연주법에 대한 알고리즘이 요구된다. 본 연구에서는 아코디온의 효율적인 연주를 위하여 손가락 연주의 알고리즘을 패트리 넷으로 표현하여 화음과 멜로디의 관계성을 표현하였다. 또한 사례를 들어 모델링을 검증하였다.

In this study, the controller structure and control algorithm of medical robot bed developed for pressure ulcer prevention and healing are described. The existing pressure ulcer prevention mattress is operated manually and the remaining maximum body pressure exceeds the pressure of ulcer generation, so there is always room for pressure ulcers. However, the system developed in this study does not generate the pressure ulcers because the body pressure drops to zero when the keyboard of the bed descends using the active electric driving keyboard. In addition, even if the bed is raised and the pressure above the critical body ulcer pressure is abnormal, the device and the control algorithm are designed so that the lasting time is within the pressure ulcer generation critical time and the pressure ulcer itself is not generated. The bed key board motor is a motor designed with the BLDC servos suitable for medical use and these can communicate each other easily through CAN(Car Area Network). The system is new medical robot bed that is effective in preventing pressure ulcers and will be distributed to many patients suffering from pressure ulcers.

This paper is aimed at more carefully studying C. P. E. Bach's Fugues, which have been relatively less appreciated in his study. Fugue is the most sophisticated music with its highly contrapuntal texture, and it is often paired with the contrasting Prelude or Fantasia. C. P. E. Bach introduces an unprecedented attempt by merging seemingly contrasting Fugue and Improvisational passages into one piece of music rather than simply placing the two music pieces side by side. In his unprecedented attempt, the basic concept and typical form of Fugue are roughly maintained, but the insertion of improvisational performance techniques in both the subject and the detailed progression takes great importance. This Study examines the connection of C. P. E. Bach's Fugue and Improvisational Techniques by analyzing his 7 Fugues.
