The purpose of this study is to research into an application of a project-based music learning model for the juniors of the applied music department and thereby, provide for some insights for the teaching-learning methodology about the applied music. For this purpose, the Kilpatric's phased model of purpose-planning-execution-evaluation was applied for 123 students who were divided into 15 groups for a project class. Upon evaluating the effects of the project class in both terms of quality and quantity, the following suggestions could be drawn. First, it is deemed essential to introduce and use the project class not only for the practical education but also for some similar classes. Second, the project-based class should be operated according to a series of the phases ranging from learner-based planning to evaluation. Here, the participants need to be organized properly. Third, when the project-based learning is applied to the college curriculum, the major subjects needs to be taken into consideration.

In this Paper, we studied the mechanism that increases the network reliability and decreases network load in GMAHN environment based on the AODV routing protocol. This proposed algorithm is the research on the algorithm, minimizing network overhead by preventing unnecessary network overhead previously and adapting Local repair mechanism to efficient data transmission when route error happens in network, in GMAHN environment. To evaluate the proposed algorithm's performance, we analyzed the proposed algorithm and adapting in various experiment environment according to 5 experiment viewpoint such as node movement, gateway network zone, mobile node number, flow number. After evaluating the experiment, we confirmed better network improvement altogether through following result such as total average data reception rate's increase, average data transmission time's decrease, network overhead's decrease than existing GMAHN algorithm.

클라이언트로부터 전송되는 인증 데이터를 실시간으로 서버에서 분석하여 처리하는 시스템의 경우에는 입력되는 데이터의 양에 비례하여 서버의 부담은 증가하게 된다. 이때 서버에서는 데이터의 병목현상이 발생하게 되고, 이는 바로 전체적인 시스템의 성능을 저하시키는 결과를 초래하게 된다. 본 논문에서는 데이터 처리의 병목현상을 해결하여 시스템의 성능을 높일 뿐만 아니라, 인터넷상의 유휴 서버들을 활용할 수 있게 하기 위한 방안으로 분산처리 기술을 이용한 전처리 작업 시스템과 그 성능을 향상시키기 위한 분산 객체 활성화 시스템을 제안한다.

Recently, GMAHN that provides interface between MANET and Wired Network has been focused in Mobile Communication. It is necessary that The technology provide reliable data transmission technology between mobile node and wired network in MANET environment that varing by the node movement. In this paper, using the TCP protocol(Tahoe, Reno, Vegas, SACK)that increases reliability between source and destination, we applied the TCP protocol mechanism to various environment, and compared result, and also proposed the efficient TCP mechanism by comparing each mechanism.

최근 사용자 친화형 유저 인터페이스 구현을 위해 인간의 손 형상을 실시간으로 인식하는 연구의 중요성이 부각되고 있다. 그러나 인간의 손은 자유도가 크기 때문에 손 형상을 정확히 인식하기란 매우 어렵고 또한 피부색과 유사한 색을 가지는 복잡한 배경에서는 더욱 곤란하다. 본 논문에서는 별도의 센서를 부착하지 않고 카메라를 사용하여 피부색 정보에 의한 손 형상을 분할한 후 손가락 끝 점을 찾는다. 찾은 손가락 끝 점을 이용하여 방향을 탐지하는 알고리즘에 대해 기술한다. 이 방법은 템플리트 매칭을 이용하여 손가락 끝 점을 탐색한 후 찾은 손가락 끝 점과 손목의 중심을 이용하여 전, 후, 좌, 우 방향을 탐지한다. 제안하는 방법을 이용하여 3D 가상현실 공간에서의 네비게이션(Navigation)에 응용하였으며, 실험결과 전진, 후진 및 좌측, 우측의 방향전환도 매우 좋은 결과를 보였다. 또한 본 논문에서 제안하는 방법은 마우스, 키보드, 조이스틱 등의 조작 없이 전, 후, 좌, 우 방향전환을 사용자가 직관적으로 지시함으로써 보다 자연스러운 인간과 컴퓨터의 상호작용을 제공할 수 있을 것이다.

We do not use dedicated Bosch process equipment of high cost, it is uses Bosch process that fit existent ICP(Inductively Coupled Plasma) equipment. Bosch process which is method of deep silicon etching is connected repeatedly in using SF? Plasma for etching process and using C₄F? Plasma the deposition process. However, between etching bottom layer and side wall not verticality and curved layer is formed. It is used about this curved layer phenomenon. because of considering gas fraction, temperature, substrate voltage, process time etc. It is used about this curved layer phenomenon and suggested optimum process condition. Standard process for study of process gas used SF? and Ar, and source power 600W, substrate voltage used -200V. Deposition process used C₄F? gas, and source power 600W, substrate voltage did not used. Process substrate temperature makes via 0℃ and progressed study. Through these processing condition, we manufactured mold for NIL(Nano Imprint Lithography) process.

The unit-water content of concrete is one of the important factors in determining the quality of concrete and is directly related to the durability of the construction structure, and the current method of measuring the unit-water content of concrete is applied by the Air Meta Act and the Electrostatic Capacity Act. However, there are complex and time-consuming problems with measurement methods. Therefore, high frequency moisture sensor was used for quick and high measurement, and unit-water content of mortar was evaluated through machine running and deep running based on measurement big data. The multi-input deep learning model is as accurate as 24.25% higher than the OLS linear regression model, which shows that deep learning can more effectively identify the nonlinear relationship between high-frequency moisture sensor data and unit quantity than linear regression.

The superior vena cava (SVC) syndrome refers to all clinical phenomena appeared as bronchial pneumonia, lymphoma, mediastinitis, and aortic aneurysm compress the superior vena cava and the veins in the vicinity in the superior mediastinum. Iatrogenic superior vena cava syndrome due to vascular stenosis or aneurysmal change has occurred by the repeated placement of cardiac pacemaker. Cardiac tamponade and hematoma have been reported in patients with end-stage renal disease due to impairment of blood coagulation caused by uremia. But acutely developed SVC syndrome was not reported after catheterization. In this report, we describe a case of acute SVC syndrome and mediastinal hematoma after insertion of internal jugular catheter for hemodialysis.
