인간 유전체 지도 완성 후 NGS 기술의 발달로 대용량 유전체 데이터 분석에 대한 요구가 증대하였다. NGS 데이터는 대용량의 단편서열로 구성되므로 효과적인 분석을 위해 고성능 컴퓨팅 기술의 지원이 요구된다. 본 연구에서는 HPC 환경에서 NGS 데이터로부터 SNP를 탐색하는 유전체 분석 파이프라인을 구축하였다. 각 분석 단계의 CPU 이용률 분석을 통해 분석 단계 중 서열 정렬 단계가 연산 작업의 비율이 가장 높은 것을 확인하고, 공개된 병렬화 서열 정렬 도구들의 성능을 분석하여 유전체 분석를 위한 매니코어 프로세서의 활용 가능성을 확인하였다.

We have studied effect of Patterned Vertical Alignment (PVA) mode on electro-optical characteristics and stability of liquid crystal director upon electrode pattering. In the present studies, LC director field and stability of conventional PVA mode electrode patterns were analyzed and new type of electrode patterns were suggested. At last, comparison between this new type of electrode patterns to conventional electrode pattern types were followed.

MiRNA is a biological short sequence, which plays a crucial role in almost all important biological process. MiRNA patterns are common sequence segments of multiple mature miRNA sequences, and they are of significance in identifying miRNAs due to the functional implication in miRNA patterns. In the proposed approach, the primary miRNA patterns are produced from sequence alignment, and they are then cut into short segment miRNA patterns. From the segment miRNA patterns, the candidate miRNA patterns are selected based on estimated probability, and from which, the potential miRNA patterns are further selected according to the classification performance between authentic and artificial miRNA sequences. Three parameters are suggested that bi-nucleotides are employed to compute the estimated probability of segment miRNA patterns, and top 1% segment miRNA patterns of length four in the order of estimated probabilities are selected as potential miRNA patterns.

We demonstrated the capillary force lithography (CFL) method for controlling the azimuthal anchoring energy of a liquid crystal (LC) alignment layer. When a thermoplastic polymer film is heated to over the glass transition temperature, the melted polymer is filled into the mold structure by the capillary action and the aspect ratio of the pattern is determined by the dewetting time of the CFL process. Here, the proposed method showed that the azimuthal anchoring energy of the LC alignment layer could be simply controlled by the surface relief patterns which were determined by the dewetting times during the CFL patterning.

Using tightly focused femtosecond laser pulses, we produce an optical waveguide and devices in transparent materials. This technique has the potential to generate not only channel waveguides, but also three-dimensional optical devices. In this paper, an optical splitter and U-grooves, which are used for fiber alignment, are simultaneously fabricated in a fused silica glass using near-IR femtosecond laser pulses. The fiber- aligned optical splitter has a low insertion loss, less than 4 dB, including an intrinsic splitting loss of 3 dB and excess loss due to the passive alignment of a single-mode fiber. Finally, we present an output field pattern, demonstrating that the splitting ratio of the optical splitter becomes approximately 1:1.

This study is to stimulate the model of which top notch muscle stimuli physical therapy has been made on the basis of GCM. GCM has been studied on the hypermobility & hypomobility pattern on the part of spine & extremity, and the body characteristics of four body types, which is the tilting of seal scapular & ilium. The purpose of this study is to analysize the type of GCM which has been focused on the spine & extremity for the patients having dysfunctions of neuromuscular system, being analysized the movement. The result of this study is as following; 1) The First hypothesis: The hypermobility & hypomobility pattern assorted by the tilting of scapular & ilium, as does the former study analysize was claimed that it would be in line with the pattern for hypermobility hypomobility and physical characteristics according to each body type at the percentage of at least 60(p<.001). 2) The 2nd hypothesis : Stimuli therapy of muscle dealing with physical characteristics and joint hypermobility hypomobility has the important role in restoring the deformity and keeping anatomical postural plumb alignment also it would a highly effects on correcting the body even though the stimuli area was limited to four areas and it was lack of time compared with those applied by general physical therapy(p<.001). As above the result, the top-notch type for physical therapy based on hypermobility hypomobility pattern by 4 body types which has been studied on tilting of scapular & ilium is more specificed and specialized than those of general physical therapy technologies. So this study will be believed to dedicate to restoration ideal anatomical postural plumb alignment based on spinal Manipulation and the concept of whole person as well as to being simple and effective to apply.

This study developed the conductivity pattern of solid surface using laser direct pattern and compound polymer material technology. For development direct patterning system of solid surface, we used the laser power stabilizer, the dynamic focusing, 3D scanner S/W and the auto aligning techniques. Also For conductivity pattern, we are developed compound polymer material with additive by electro-less plating. These technologies are already used commercially. However operation and control integrated system for direct patterning of solid surface are not yet developed. The objective of this paper is to introduce the laser direct structuring for simple process improvement instead complex PCB process, and develop the operating stability and integration system. Also we implemented new application of laser direct structuring through sample manufacture.

This paper presents the pattern characteristic using the electrostatic drop-on-demand ink-jet printing system. In order to achieve the pattern characteristic of electrostatic inkjet printing, the capillary inkjet head system is fabricated using capillary tube, Pt wire and electrode, and is packaged by acrylic board for the accurate alignment between wire and electrode-hole. The applied DC voltage of 1.4 $\sim$ 2.0 kV used for the observation of electrostatic droplet ejection. Electrostatic droplet ejection is directly observed using a high-speed camera. For investigated pattern characteristic, conductive inkjet silver ink used. The higher voltage has a good condition which has micro dripping mode. Also, the droplet size decreases with increasing the supplied DC voltage. This paper shows the pattern which is formed by about 300um. Also, capillary inkjet head system will be applied industrial area comparing conventional electrostatic inkjet head system.

The measuring method of large object using the pattern matching is discussed in the paper. It is hard and expensive to get the complete 3D data when the object is large or exceeds the limit of measuring devices. The large object is divided into several smaller areas and is scanned several times to get the data of all the pieces. These data are aligned to get the complete 3D data using the pattern matching method. The point pattern matching method and transform matrix algorithm are used for aligning. The laser slit beam and CCD camera is applied for experimental measurement. Visual C++ on Window98 is implemented in processing the algorithm.

본 연구의 목적은 농구동호인의 만성발목관절불안정성(CAI)에 따른 한발착지패턴의 변화를 확인하고 비교분석하고자 하였다. 현재 부산광역시에서 레크레이션 농구경기에 참여하고 있는 농구동호인 30명을 대상으로 국제발목협회에서 제공하는 CAI 표준 선정기준에따라 CAI집단 21명과 CON집단 9명으로 분류하였다. 한발착지패턴을 측정하기 위해 초기접촉 시점 및 무릎관절 최대 굽힘 시점에서 하지정렬과 관절 움직임을 측정하고 초기접촉 시점, 발꿈치접촉 시점 및 무릎관절 최대 굽힘 시점에서 앞정강근, 긴종아리근, 안쪽장딴지근 및 중간볼기근의 활성도를 측정하였다. 그 결과, 집단 간 단일 다리 드롭랜딩 시 하지정렬과 하지 근활성도는 유의한 차이를 보이지 않았다. 이런 결과는, CAI에 따라 한발착지패턴과 근활성도에 유의한 차이가 없다는 것을 보여주었다. 추후 연구에서는 CAI를 세부적으로 구분하고 경기포지션을 고려하여 움직임의 특성 및 기능적 요구의 차이를 반영해야 할 것으로 생각된다.
