통신 시장의 경쟁 심화, 급속한 기술 발전은 All-IP 기반의 공통 인프라와 다양한 고품질 융합 서비스의 환경으로 패러다임을 변화시키고 있으며, 이러한 변화에 따라 IP 서비스에 대한 과금 체계 또한 진화하고 있다. 본 고에서는 그 중요성이 증대하고 있는IP 서비스의 과금 시스템에 대하여 개념과 기술 동향, 관련 표준화 활동을 살펴보고, 차세대 네트워크(BcN)를 대비한 과금 정책에 대하여 기술한다. 그리고 이와 같은 기술동향 및 과금 정책을 효과적으로 구현하기 위해 ETRI에서 개발중인 고속회선용 정밀과금 시스템을 소개한다.
New species of Halichondria (Suberitida: Halichondriidae) from Korea
강동원,김하나,김형준 국립중앙과학관 2022 Journal of Asia-Pacific Biodiversity Vol.15 No.1
In this study, a new species of the genus Halichondria Fleming, 1828: Halichondria dokdoensis sp. nov. from Korea, was newly described. Morphologically distinct from each other, the new species wasassigned to the genus Halichondria. Halichondria dokdoensis sp. nov. has encrusting with a chimney shapeand volcano shape, reddish-purple color, and a large extensive subchoanosomal space present.

We successfully designed and experimentally demonstrated anapplication of patterned MgF2 dielectric material at rear Al-dopedZnO (AZO)/Ag interface in thin film amorphous silicon oxide (a-SiOx:H) solar cells. When it was realized in practical deviceprocess, MgF2 coverage with patterned morphology was employedto allow for current flow between the AZO and Ag against highlyresistive MgF2 material. On the basis of the suggested structure, wefound an improvement in quantum efficiency of the solar cells withthe patterned MgF2. In addition, an enhancement of open circuitvoltage (Voc) and fill factor (FF) was observed. A remarkableincrease in shunt resistance of the cells with the MgF2 wouldpossibly indicate that the highly resistive MgF2 layer can partlysuppress physical shunting across top and bottom electrodes causedby very thin absorber thickness of only 100 nm. The approachshowed that our best-performing device revealed an essentialimprovement in conversion efficiency from 7.83 to 8.01% withachieving markedly high Voc (1.013 V) and FF (0.729).

We report p-type a-SiOxCy:H thin films which were fabricated byintroducing additional Trimethylboron (TMB, B(CH3)3) dopinggas into conventional standard p-type a-SiOx:H films. The TMBaddition into the condition of p-a-SiOx:H improved opticalbandgap from 2.14 to 2.20 eV without deterioration of electricalconductivity, which is promising for p-type window layer of thinfilm solar cells. The suggested p-a-SiOxCy:H films were appliedin amorphous silicon solar cells and we found an increase ofquantum efficiency at short wavelength regions due to widebandgap of the new p-layer, and thus efficiency improvementfrom 10.4 to 10.7% was demonstrated in a-Si:H solar cell byemploying the p-a-SiOxCy:H film. In case of a-SiOx:H cell, highopen circuit voltage of 1.01 V was confirmed by using thesuggested the p-a-SiOxCy:H film as a window layer. This new playercan be highly promising as a wide bandgap window layer toimprove the performance of thin film silicon solar cells.

Objectives : To investigate aggravating and mitigating factors of atopic dermatitis and to utilize the outcome in treatment planning. Methods : The research has a cross-sectional study design. Patients’ SCORing Atopic Dermatitis (SCORAD) Index, demographic, physical characteristics, social history, serologic index and skin related instrumental measurements were analyzed with correlation and regression analysis method. Results : 48 patients in total were enrolled in the study. Skin Surface Hydration (SSH) and sex were found to be statistically significant aggravating and mitigating factors. As SSH increased, Total SCORAD (tSCORAD) and Objective SCORAD (oSCORAD) increased as well. As SSH decreased, tSCORAD and oSCORAD decreased as well. Female patient had a higher probability of suffering from severer subjective symptoms than that of male. Age, body mass index (BMI), alcohol consumption and smoking, transepidermal water loss (TEWL), IgE, IL-4, IL-5, IL-6, IFN-γ were found not to be statistically significant. There was no correlation between Subjective SCORAD (sSCORAD) and oSCORAD neither with Eczema Area and Severity Index (EASI). Conclusions : Increasing cutaneous moisture should be included in the treatment plan of atopic dermatitis. More emphasis should be put on alleviating subjective discomforts of female patients than that of male. Establishing separate strategies of managing objective eczema status and subjective discomforts respectively should be considered.

Objectives : To investigate treatment approaches of psoriasis, and to provide universal and holistic standards to assist in optimizing patient care and future research. Methods : Review articles of psoriasis regarding pathophysiology, risk factor or treatment were searched from Pubmed (January 2016 to June 2020). Treatment approaches were investigated based on the searched articles. Additional data collecting was done for further discussion by searching Pubmed and Google scholar with keywords relevant to the approaches, and the relevant references of articles retrieved were manually inspected to be included. Results : Modalities to directly regulate the relevant helper T cell or inflammatory cytokines can constitute the treatment approaches of psoriasis. Modalities to treat gastrointestinal tract inflammation, to correct metabolic syndrome and to improve epidermal lipid abnormality via whole body lipid metabolism can also constitute the treatment approaches of psoriasis. Probable adverse effects of long term use of western medication should be addressed carefully, and alleviating the hazards of western medication can be a treatment approach of psoriasis. Conclusion : Treatment of psoriasis should take account of systemic aspects such as gastrointestinal tract and lipid metabolism. Treatment approaches of psoriasis established on the pathophysiological basis can serve as universal standards.
