The purpose of this study is to analyze the types and discourse structures online hate speech against women. To this end, five Internet articles dealing with The Gangnam Station Murder Case 2 Cycle were selected. And analyzed the comments and replies on each article. As a method of analysis, critical discourse analysis by Norman Fairclough was used to analyze text and discourse structure dimensions. Online hate speech against women was divided into categories of appearance and properties related to temper. Each upper category discourse was based on nine sub-discourses. The nine sub-discourses were the basis for each other or acted as a reinforcement and sub-element, and maintained and expanded misogyny discourse. As an attempt to face and solve the problem situation of hate speech against women in the internet space, it is necessary to consider the practical action plan to solve the problem of hate speech against women.

본 논문에서는 바이스태틱 MIMO(Multi-Input Multi-Output) 레이더 시스템에서 다중 신호의 DOA(Direction of Arrival)의 추정을 위한 2차원 Matrix Pencil Method(MPM) 기반 알고리즘을 제안하였다. 2차원 MPM은 낮은 SNR 환경에서도 기존 알고리즘에 비해 적은 연산량으로 다수의 DOA 추정이 가능하고, 송신기에서의 표적 각도인 DOD(Direction of Departure)도 동시 추정이 가능하다. 본 알고리즘의 성능을 확인하기 위해 등간격 선형 배열구조의 MIMO 레이더 시스템에서 SNR에 따른 DOA 및 DOD의 RMSE(Root Mean Square Error)를 확인하였고, 2차원 Capon 기법과 비교하였다. In this paper, we apply the 2-D Matrix Pencil Method(MPM) to the estimation of the direction of arrival(DOA) of multiple signals of interest(SOIs) in bistatic MIMO radar. The 2-D MPM shows remarkable performance under a low SNR environment and low computational complexity to estimate the DOA of multiple SOIs. Also, it is possible to estimate the direction of departure(DOD) which is an angle from transmitter to target. To verify the proposed algorithm, we applied the proposed algorithm to a uniformly spaced linear array(ULA) and compared the RMSE(Root Mean Square Error) of DOA and DOD under the various SNR with those of the 2-D Capon algorithm.

Lung cancer and pulmonary metastasis are the leading cause of cancer mortality worldwide. Survival for patients with lung metastases is about 5%. Nanoparticles have been developed for the imaging and treatment of various cancers, including pulmonary malignancies. In this work, we report lipid coated polymeric nanoparticles (LPNs) with an average diameter of 154 nm. In vivo performance of LPNs was characterized using optical imaging system. We expect this nanoparticle can be used for finding lung cancer or lung metastasis. Eventually loading therapeutic drug with the nanoparticle will be utilized for cancer diagnosis and effective therapy at the same time.
