This study evaluated the potential of hemp seed oil (Cannabis sativa L. seed oil, CSO) and hemp seed oil complex (Cannabis sativa L. seed oil complex, CSOC) as an anti-inflammatory material through comparative analysis. Anti-inflammatory effects of CSO and CSOC were confirmed through lipopolysaccharide (LPS)-induced RAW264.7 model. As a result of confirming the inhibition of lipid oxidation through lipoxygenase inhibitory activity, CSO was not inhibited, but COSC was inhibited by more than 70%. As a result of confirming cytotoxicity through MTT analysis, CSO did not show cytotoxicity, but CSOC showed cytotoxicity at over 200 ㎍/ml. In LPS-induced RAW264.7, the expression of inducible nitric oxide synthase (iNOS) and the production of nitric oxide (NO) were significantly inhibited by CSOC compared to CSO. Additionally, CSOC significantly inhibited the expression of cyclooxygenase (COX)-2 and the production of prostaglandin E₂ (PGE₂). Through this study, we confirmed that CSOC has superior anti-inflammatory effects than CSO and has the potential to be used as an anti-inflammatory material.

Threat hunting is defined as a process of proactively and iteratively searching through networks to detect and isolate advanced threats that evade existing security solutions. The main concept of threat hunting is to find out weak points and remedy them before actual cyber threat has occurred. And HMM(Hunting Maturity Matrix) is suggested to evolve hunting processes with five levels, therefore, CSOC(Cyber Security Operations Center) can refer HMM how to make them safer from complicated and organized cyber attacks. We are developing a system for cyber situation awareness system with pro-active threat hunting process called unMazeTM. With this unMaze, it can be upgraded CSOC's HMM level from initial level to basic level. CSOC with unMaze do threat hunting process not only detecting existing cyber equipment post-actively, but also proactively detecting cyber threat by fusing and analyzing cyber asset data and threat intelligence.
