Objectives : Recent studies reported that Dokwhalkisaeng-tang (DHJST) could relieve the clinical rheumatoid arthritis (RA) symptoms and the level of RA-related blood test. However, evidence-based review on effectiveness and safety of DHJST with medication on RA was not yet provided. Methods : Searching randomized controlled trials on the use of DHJST for RA will be performed using multiple electronic databases, manual search, and contact to author. Studies will be selected according to the pre-defined criteria and collected data on study participants, interventions, control groups, outcome measurements, the results, adverse events, and risk of bias will be summarized. Primary outcome will be the disease activity score (including effective rate, swollen joint count, tender joint count, and morning stiffness), and the secondary outcomes will be RA-related blood test and adverse events. We will use Review Manager software to perform a meta-analysis, Cochrane Collaboration "risk of bias" tool for assessing the risk of bias, and Grades of Recommendation, Assessment, Development and Evaluation for the determination of quality of evidence. Results : We are going to investigate the effectiveness and safety of DHJST with medication for RA. Conclusion : This study will provide reliable evidence on whether DHJST combined with medicine is more effective on RA than medicine monotherapy.

The diamagnetic six-coordinate ruthenium polypyridyl complexes have been prepared and assigned. 1H NMR spectral studies were used to unravel the ligand field strength and the basicity on the chemical shift to the particular proton of ligand L in [(tpy)(L)RuⅡ(X)]+/2+ (L=bpy, bqi, dmbpy, phen; X=Cl, CN, N3, NCCD3, NO2, SCN) complexes.

비디오 영상은 파일이 크기 때문에 다운로드가 완료된 다음에 재생을 시작하는 것이 아니라 수신이 되는 대로 재생이 되어야한다. 이와 같은 스트리밍 서비스는 주문형 비디오 서비스를 비롯한 다양한 상용시스템에 필수요소이다. 스트리밍 기능을 제공하는 여러 가지 서버 중, 본 논문에서는 다윈 스트링 서버를 설치하고 주문형비디오 서비스 시스템을 구축하는 방법을 소개한다.

In recent years, security has been more and more significant in network environment. The internetworkding communication including ATM network will be exposed to all kinds of attacks, such as eavesdropping, spoofing, service denial and traffic analysis etc. So, in this paper, we focused on ATM network threats, security service and ATM security mechanisms for threats.

본 논문에서는 다중 스케일로 구성된 뉴럴 네트워크를 이용하여 영상 내 모아레 무늬을 제거하는 기법을 제안한다. 제안하는 기법은 영상 피라미드를 생성하여 모아레 무늬를 구성하는 다양한 주파수 범위의 정보를 제거한다. 각 branch는 Multi-scale Feature Block (MFB)과 Tone-Mapping Block (TMB)으로 구성하여 효과적으로 모아레 현상을 제거하고 저하된 색상 저하를 복원한다. 컴퓨터 모의실험을 통해 제안하는 기법이 기존 기법에 비해서 높은 모아레 제거 성능을 보이는 것을 확인한다.

The nose is a complex three-dimensional structure and represents a major aesthetic focus of the face. As a gold standard for nasal soft tissue reconstruction, the 'forehead flap' provides reconstructive surgeons a robust pedicle and large amount of tissue to reconstruct almost any defect. However, during this process, some hair can be unintentionally introduced to the nose. Accordingly, laser hair removal is sometimes needed, but blood circulation and flap survival should be carefully monitored. Despite careful evaluation, a third-degree burn occurred in our patient that required eight weeks to heal. Here, we report on a burn resulting from epilation conducted 2 weeks after forehead flap for nasal reconstruction.

Objectives : In this study, we investigated the cytoprotective effect of Eriobotrya japonica L. (EJ) extract against Arachidonic acid (AA)+iron-induced oxidative stress. Methods : To confirm the cytoprotective effect of EJ against AA+iron-induced oxidative stress in HepG2 cells, it was evaluated by MTT assay, immunoblot anaylsis, and Calcein-AM/propidium iodide (PI) staining. Additionally, the mechanism of action of the cytoprotective effect was evaluated through molecular mechanisms. Results : EJ (100 ㎍/mL) inhibited Arachidonic acid (AA)+iron-induced cell death in a concentration-dependent manner. It also inhibited AA+iron-induced mitochondrial dysfunction and ROS production. EJ activated the LKB1-AMPK signaling pathway. Conclusions : In conclusion, EJ has the ability to protect liver cells from oxidative stress, indicating that it is related to AMPK-LKB1 signaling pathways.

Antioxidant activities of various mushroom fruiting bodies were investigated in vitro. Among the mushroom extracts examined, Armillariella mellea, Daedalea dickinsi, Fomitella fraxinea and Pleurotus cornusopiae markedly exhibited inhibition on lipid peroxidaton of rat liver microsomes. Ergosterol peroxide (5,8-epidioxy-5α,8α-ergosta-6,22E-dien-3β-ol), antioxidant from A. mellea, was isolated by solvent extraction, silica gel column chromatography and recrystallization. The structure of the compound was determined by NMR, GC/MS and X-ray crystallography. Ergosterol peroxide showed potent inhibition on lipid peroxidation and exhibited higher antioxidant activity than well-known antioxidants, α-tocopherol and thiourea.
