An Unmanned Aerial Vehicle (UAV) is a powered pilotless aircraft, which is controlled remotely or autonomously. UAVs are an attractive alternative for many scientific and military organizations. UAVs can perform operations that are considered to be risky
This research is to select a path planning algorithm to maximize survivability for Unmanned Aerial Vehicle(UAV). An UAV is a powered pilotless aircraft, which is controlled remotely or autonomously. UAVs are currently employed in many military missions(surveillance, reconnaissance, communication relay, targeting, strike etc.) and a number of civilian applications(communication service, broadcast service, traffic control support, monitoring, measurement etc.). In this research, a mathematical programming model is suggested by using MRPP(Most Reliable Path Problem) and verified by using ILOG CPLEX. A path planning algorithm for UAV is selected by comparing of SPP(Shortest Path Problem) algorithms which transfer MRPP into SPP.
Motorola developed the framework of six sigma in 1987. In these days, many companies adapt this powerful tool. In 1996, six sigma was introduced to the Korean companies as a management innovation tool. This study shows case study of ‘Champion Project’ w
In recent dates, Internet advertising effects are expanded by the steep increment of the Internet users and the extension of the advertising market will be accelerated through Internet. This paper indicates the importance of Internet advertising and suggests the solution of a network advertising service. The system is divided into an Advertise Server, an Advertiser and a Web Publisher. This study proposes both the collection and the analysis of traffic data in real time. Also, the banner advertising frames are smoothed for the impression using the solution for the banner exchange engine and are developed using various impression methods, that is, Fixed/variable Banner, Scheduling Banner, Multi-Impression Banner, and Frame Remote Control to increase the advertising effect. And then to increase the advertising effect web publisher, which is specialized in lottery site, is constructed using the network advertising service and various advertising technology.

The effects of cutting 6equency and nitrogen fertilization on feed values of reed canarygrass were investigated in uncultivated rice paddy and the attemp was made to estimate the economical and efficient levels of nitrogen fertilization for the increased
Next generation sequencing (NGS) technologies provide a fast and easy way to understand the plant genomes, transcriptomes, regulatory elements and their interactions. About a decade ago, rice was the only crop that whole genome sequence information was publicly available but today many agricultural crops including maize, soybean, tomato, potato, cotton have been sequenced and many more will be available. Moreover newly developed method such as Genotyping-By-Sequencing (GBS) allows efficiently collecting sequence information from hundreds of individuals in population to identify genetic variations, detect quantitative trait loci (QTLs) and develop molecular markers. Coupled with high-throughput phenotyping, the accumulated genomic information will be effectively utilized in crop improvement by genomics-assisted breeding, genome-wide association mapping (GWAS) and genomic selection (GS). Rice is one of the important staple crops providing daily nutrition to more than a half of the world population. The genus Oryza consists of 23 species including two domesticated rice and it has been classified into 10 distinct genome types, represented by six diploids (A, B, C, E, F, and G) and four allotetraploids (BBCC, CCDD, HHJJ, and HHKK). It shows wide ranges of phenotypic variations to biotic and abiotic stress thus is considered a genetic reservoir of unique allelic variation for rice improvement. International collaborative efforts have been focused on generating the Oryza genomics resources including reference genome, transcriptome, smallRNAs, methylome and resequencing of many accessions to collect genetic variations and better understand the 15 MY evolution of Oryza. The Oryza genomic resources will be a backbone to layer various omics data to catalogue more genetic variations within and between Oryza species and the untapped genetic diversities existing in wild Oryza species will be finally translated to crop improvement.
동영상 피드백의 효과를 조사한 선행연구들의 결과에 따르면 동영상 피드백이 긍정적인 학습효과를 발생시키기 위해 학습자에게 단독으로 제공되어서는 안 되고 주의집중 단서, 오류수정 정보, 전문가 모델 동영상 등과 함께 결합되어 제공되어야 하는 것으로 밝혀졌다. 본 연구의 목적은 운동학습 효과를 극대화하기 위해 동영상 피드백을 어떻게 제공해야 하는지 규명하기 위해 위 요인들의 결합된 효과를 조사 하였다. 구체적으로 선행연구들이 가장 효율적인 동영상 피드백 제공방법으로 제시한 ‘오류수정 정보+학습자 동영상’ 제공조건에 언어적 주의집중 단서와 전문가 모델 동영상이 부가될 때의 학습효과를 조사하였다. 40명의 피험자들은 네 가지 동영상 피드백 제공집단으로 나누어 땅볼 인사이드 축구 패스를 연습하였다. 24시간 후에 실시된 파지검사 결과, ‘오류수정 정보+학습자 동영상’ 조건에 주의집중 단서가 부가되었을 때 학습효과는 다르게 나타나지 않았다. 그러나 전문가 모델 동영상이 추가로 제공되었을 때 학습효과는 가장 우수했다. 부가된 전문가 모델의 동영상은 학습자에게 오류탐지를 위한 견본으로 사용된 것처럼 보인다. 또한 전문가 모델 동영상은 관찰학습 효과와 신체분절의 상대동작 정보를 제공하여 동작 폼의 습득을 더 용이하게 하는 것처럼 보인다. 그러나 동영상 피드백에 오류수정 정보가 결합될 경우 주의집중 단서의 추가적 제공은 불필요 한 것처럼 보인다.
