본 논문에서는 알려진 악성코드로부터 악의적인 행위 패턴을 정의하는 방법을 제안하고, 이를 기반으로 변형된 악성코드의 검출 방법을 제안한다. 악의적인 행위 패턴에 대한 정의는 Cross Reference를 기반으로 블록화 한 후 실행코드 블록의 호출 관계에 따른 그래프를 이용하여 정의하였다. 그리고 변형된 악성코드에 대한 검출은 실행코드 내부에서 악의적인 행동 패턴을 찾음으로써 판단한다. 제안된 방법에 대한 실험결과 변형된 악성코드의 검출이 가능함을 확인하였다.

In order to evaluate the anti-tumor and synergic effect of BoJungIkKeeHapDaeChilKi-Tang on doxorubicin, the inhibitory concentration(IC), IC50 and IC90 of single use of doxorubicin and BoJungIkKeeHapDaeChilKi-Tang with their concomitant treatment against MKN-45(Human stomach carcinoma) was observed using MTT(Microculture Tetrazolium test) assay. In addition, their anti-tumor effects were also observed in the xenograft nude mice models agianst MKN-45 cell lines. BoJungIkKeeHapDaeChilKi-Tang has only mimic direct anti-tumor effect against to MKN-45 cell lines but they were decreased general depressed signs induced by implantation of tumor cell lines and increased the total WBC and lymphocyte numbers. So, it is considered or expected that BoJungIkKeeHapDaeChilKi-Tang extracts were reduced by the critical toxicity of doxorubicin and shows favorable synergic effect with doxorubicin and BoJungIkKeeHapDaeChilKi-Tang extracts.

Phytochemical studies on the leaves of Ailanthus altissima (Simaroubaceae) have not been reported previously. Thus, the authors isolated and identified secondary metabolites from A. altissima. Dried and powdered leaves were extracted with 80% aqueous methanol, and the concentrated extract was successively partitioned with ethyl acetate, n-butanol, and water. Four flavonoids were isolated from the ethyl acetate fraction through repeated silica gel and octadecyl silica gel column chromatography. Spectroscopic data including NMR, MS, and IR allowed for identification of the chemical structures as quercetin (1), afzelin (2), quercitrin (3), and isoquercitrin (4). This is the first report of the isolation of these compounds from A. altissima. The four isolated flavonoids 1-4 as well as solvent fractions (ethyl acetate, n-butanol, and water), were evaluated for DPPH radical scavenging activity.

Objectives: The purpose of this study is to investigate the effectiveness of moxibustion for primary dysmenorrhea (PD). Methods: We searched 10 electronic databases (CNKI, WANFANG, VIP, AMED, CiNii, Embase, PubMed, Cochrane, OASIS, Korea Traditional Knowledge Portal) to identify eligible studies published before November 2016. We included randomized controlled clinical trials (RCTs) using moxibustion for primary dysmenorrhea. The methodological quality of each RCT was assessed by the Cochrane risk of bias tool. Results: Ten RCT studies were eligible in our review. The overall risk of bias was evaluated as unclear. The meta-analysis of 4 trials indicated that favorable results for the use of moxibustion. Conclusions: This systematic review and meta-analysis of clinical trials suggests that moxibustion can achieve good efficacy for PD patients. However, because of studies included analysis was biased due to unclear risk of bias and unreliable study design, future high-quality RCT studies are needed to determine the association moxibustion with PD.

In this letter, we propose a novel polygonal approximation of digital curves that preserve original shapes. The proposed method first detects break points, which have two different consecutive vectors, and sets an initial dominant point set. The approximation is then performed iteratively by deleting a dominant point using a novel distance, which can measure both the distance and the angle acuteness. The experimental results show that the proposed method can preserve original shapes and is appropriate for various shapes, including slab-sided shapes.

Many neurodegenerative disorders such as stroke, Alzheimer's disease, and Parkinson's disease have been known to be associated with an excessive generation of reactive oxygen species (ROS) and oxidative stress. Therefore, the antioxidants have recently received much attention as therapeutic agent for the treatment of neurodegenerative disease. (omitted)

TCP Westwood[1]는 송신측에 수신된 ACK를 통해서 대역폭을 계산하여 데이터를 전송하는 기법이다. 위성망 같이 손실률이 매우 높은 환경을 위해 TCP Westwood에서는 기존의 Bu]k Retransmission[2] 기법을 보안 하였다. 하지만 Bulk 재 전송 기법은 불필요한 데이터도 함께 재전송하기 때문에 성능이 저하되게 된다. 이 논문에서는 재 전송 패킷의 수를 적절히 조절하는 Adaptive Bulk Retransmission 기법을 제안하고자 한다.
