연구자들의 연구 주제 선정 및 연구동향 분석하기 위해서 이미 발간된 수많은 논문, 특허, 보고서에서 정보를 수집 및 분석해야 하는 어려움이 있다. 이를 극복하기 위해서 정보추출 연구와 더불어 추출된 정보의 다양한 검색 방법 연구는 필요하다. 그러나 정보추출연구는 활발히 이루어지는 반면 정보의 검색 방법 연구는 상대적으로 주목받지 못하고 있다. 본 연구에서는 고급 정보들을 다양한 방법을 통해 분석된 결과를 제시하여 사용자들이 새로운 연구 성과를 도출할 수 있는 획기적인 서비스를 소개한다.

The transmission and reflection coefficiencies of a BBDB-type floating breakwater in water of finite depth are studied taking account of fluctuating air pressure in the air chamber. The wave potential is calculated by a hybrid integral equation consisting of a Green integral equations associated with the Rankiue Green function inside the BBDB and the Kelvin Green function outside. The transmission and reflection coefficients of the breakwater are obtained directly from the potential solution in the outer region.

The $Sr_{0.7}Bi_{2.3}Nb_2O_9$(SBN) thin films are deposited on Pt-coated electrode (Pt/Ti/$SiO_2$/Si) using RF sputtering method at various deposition temperature. The crystallinity of SBN thin films were increased with increase of deposition temperature in the temperature range of 100~400[$^{\circ}C$]. The surface roughness of deposition temperature($300^{\circ}C$) showed about 4.33[nm]. The grain and crystallinity of SBN thin films were increased with the increase of annealing temperature.

The drift force acting on a floating OWC chamber in waves is studied taking account of fluctuating air pressure in the air chamber. A velocity potential in the water due to the free surface oscillating pressure patch is added to the conventional radiation-diffraction potential problem. The potential problem inside the chamber is formulated by making use of the Green integral equation associated with the Rankine Green function while the outer problem with the Kelvin Green function. The drift forces as well as the chamber motions are calculated taking account of the air pressure in the chamber.

Gait recognition has advantage of non-contact type recognition. But It has disadvantage of low recognition rate when the pedestrian silhouette is changed due to bag or coat. In this paper, we proposed new method using combination of gait energy image feature and thermal face image feature. First, we extracted a face image which has optimal focusing value using human body rate and Tenengrad algorithm. Second step, we extracted features from gait energy image and thermal face image using linear discriminant analysis. Third, calculate euclidean distance between train data and test data, and optimize weights using genetic algorithm. Finally, we compute classification using nearest neighbor classification algorithm. So the proposed method shows a better result than the conventional method.

Isophotes and surface brightness distribution were obtained for the late type normal spiral galaxy NGC 7793 (morphological type SA(s)d) which is one of the Sculptor group. The calculated total luminosity $M_{T}$ is obtained as 9.44 and the corrected face on magnitude ${B_T}^{circ}$ is 9.10. The revised distance to this galaxy $\Delta$=3.1 Mpc (de Vaucouleurs and Davoust 1980) is used for calculating the absolute magnitude ${M_T}^{circ}$ = -18.36. From the isophotes, the position angle to the major axis is $101^{circ}$, the mean axial ratio is q=b/a =0.65, and the inclination is i=50$^{circ}$. The concentric indices $C_{21}$=1069 and $C_{32}$ =1.50 are well agreed to the average value of Sd type galaxies.

본 논문에서는 무선화재감지기의 효용성 및 신뢰성을 확인하고자, 현재 가장 많이 상용화되어 있는 2.4 GHz의 주파수를 사용하는 무선모듈을 이용하여, 건물 내에서 무선통신 환경에 영향을 줄 수 있는 대표적인 장애물의 종류인 벽체를 시료로 하여 무선신호의 투과파 측정실험을 실시하였다. 실험결과 벽체 종류에 따라 무선신호의 응답특성에 차이가 나타나는 것을 확인할 수 있었다.

Inferior mesenteric plexus block(IMPB) sa useful nerve block for the relief of intractable lower abdominal and pelvic pain caused by a lower abdominal visceral or a pelvic malignancy. IMPB has been performed in the prone position. But there are many patients who can't lie in the prone position, because ascites is frequently noticed in cancer patients and they also frequently received abdominal operations. We performed IMPB in the lateral position on two patients with lower abdominal pain, Case 1: A 77 year old female who had a right ovarian cancer with metastatic cancer of descending colon and rectum, experienced complete pain relief. Case 2: A 72 year old female who had a far advance pancreatic cancer with intestinal obstruction due to carcinomatosis received right and left celiac plexus block and right and left IMPB. The patient was satisfied with the result of these pain blocks. Conclusion; IMAPB performed in the lateral position on two patients with lower abdominal pain and their results were excellent for pain relief.
