Purpose : The purpose of this study was carried out to review for the importance of breathing pattern training for the spinal stabilization. Methods : This is a literature study with books and thesis. Results : Breathing with normal respiratory mechanics has a potent role in neuro-musculo-skeletal system. The evaluation of respiratory mechanics should be a routine part of every physical examination. And respiratory mechanics must be intact for both normal posture and spinal stabilization to be possible. Conclusion : The spinal stabilization exercise with the breathing pattern training is more efficient therapeutic exercise program for the patient with neuro-musculo-skeletal system disorder.

We isolated Rice dwarf virus (RDV) from infected plants in rice fields (Korea, Japan, China, the Philippines and Nepal) and analyzed their genomic dsRNAs by polyacrylamide gel eletrophoresis. The genomic dsRNAs of the isolates showed distinct electrophoretic mobility profiles. The S12 coding to nonstructural protein of Korean isolate (RDV-Kr) was further analyzed by sequencing. The S12 of RDV-Kr was 1,066bp long and coded for a protein composed of 312 amino acids including three open reading frames of P12, P120Pa and P120Pb. The sequence identities were 96% and 98.6% with Japanese isolates (H, AN), 94.7% with Nepalese isolate (NEL), 94% with Chinese isolate (CK) and the Philippines isolate (P).

최근 초고속 인터넷이 급속히 보급되고 시스템 및 네트워크 성능의 향상으로 미디어 컨텐츠에 대한 전달을 효율적으로 제공하는 방안이 연구되고 있다. 네트워크의 성능이 향상되었다고 하더라도 미디어 컨텐츠를 스트리밍 하는 것은 인터넷 트래픽의 큰 부분을 차지한다. 그래서 이러한 컨텐츠를 효율적으로 분산시키고 서비스하기 위해서 논문에서는 P2P(Peer-to-Peer) 오버레이 네트워크를 이용한다. 스트리밍 서비스에서 반드시 보장해야 하는 것은 서비스가 끊김없이 이루어져야 한다는 것이다. 이 논문에서는 하나의 노드가 컨텐츠 전체를 스트리밍 서비스를 하는 것이 아니라 다중 디스크립션 코딩을 활용하여 여러 노드가 스트리밍 서비스를 제공함으로써 특정 노드에 문제가 발생하더라도 스트리밍 서비스가 계속해서 이루어지는 방법을 제안하였다.

본 논문은 에지부분에서 뚜렷한 영상의 복원이 가능하도록 하는 칼라 영상의 비선형 보간 기법에 관한 것이다. 일반적으로 칼라영상을 구성하고 있는 성분중 휘도신호(Y)가 에지(edge)성분에 충실한 정보를 갖고 있다는 점에 착안하여 알고리즘 연구를 수행하였다. 일반적인 선형 보간 방법을 사용할 시 영상에서 고주파 대역의 손실을 일으키므로 영상의 화질 열화가 발생한다. 이를 보완하기 위해 본 논문에서는 비선형 보간법인 에지 방향성 보간 방법을 제안하였다 또한 조밀한 에지 영역에서의 에지 방향성 보간의 단점을 극복하기 위해 선형 보간과 에지방향성 보간 기법의 혼합을 통한 화질 열화 제거 기법을 제안한다.

Based on recent studies, the side resistance of rock socketed drilled shafts was affected by unconfined compressive strength of rock, socket roughness, rock types and joints, and initial normal stress. Especially, the socket roughness was affected by rock types and joints, drilling methods, and diameters of pile. In this study, a new roughness measurement system (BKS-LRPS, Backyoung-KyungSung Laser Roughness Profiling System) usable in water was developed. Based on the laboratory model tests, an EMD (Effective Measurement Distances) according to various turbidity was proposed as EMD=$1149.2{\times}T^{-0.64}_b$.

One of representative techniques for compensation of LC's slow response characteristic is the Response Time Acceleration (RTA) technique. The conventional data definition for the RTA is based on the manual measurement and thus it takes long time. Therefore it is almost impossible to use panel specific compensation data in MP line. We have developed a new automated measurement system and flicker minimization for this purpose, which could achieve dramatic measurement time reduction, consistency over different operator, and optimized values as well. This system laid the groundwork for the application of image quality enhancement technologies to panels individually, and using this system, we can expect very uniform image quality for all LCD panels.

As far as recent investment in railway, disused railway yards is increased in each line and region. As a result, related local government and agencies has been increased interest for utilization of disused railway yard. In this study, we investigated the status of the disused railway yards and conducted legal review on the use of disused railway yards. In addition, we analyze the disused railway yards use practices through case analysis and suggest plans to diversify ways to use.
