<P><B>Abstract</B></P><P>We designed an electrical power loss model to minimize the electrical power losses in large-area monolithic organic photovoltaic (m-OPV) modules. Using the electrical power loss model, we calculated the parasitic electrical power losses on the transparent conductive oxide layer by considering the series resistance and shading losses. We fabricated a unit organic photovoltaic (OPV) cell as a reference and extracted its electrical parameters such as voltage and current density under the maximum power output condition. We calculated the electrical losses using the proposed electrical power loss model by applying these extracted parameters of the unit OPV cell. From the results of the electrical power loss model, the pattern length of the active area of a single OPV cell was determined to be 9 mm, indicating that we can place seven OPV cells in an active area of 84 mm × 90 mm.</P> <P><B>Highlights</B></P><P>► Proposed a new electrical power loss model to enhance the PCE of a monolithic OPV module. ► Calculated an optimum cell dimension using the new electrical power loss model. ► Shown the aspects of the total power loss ratio for several different shading lengths. ► Shown the aspects of the total power loss ratio for several different sheet resistances.</P>

본 연구는 RBL-2H3 세포에서 고삼의 NF-${\kappa}B$ (p65) 활성 억제를 통한 과립감소와 전염증성 시토카인 억제 효과에 관한 것으로 주요 내용은 다음과 같다. 본 연구에서는 PMA와 A23187로 유발된 흰쥐 백혈병(RBL-2H3) 세포에서 고삼의 항알레르기 효과에 대하여 알아보았다. 고삼은 투여량에 따라 $\beta$-hexosaminidase의 방출과 TNF-$\alpha$, IL-4, COX-2 등의 생성과 발현을 억제하였다. 실험결과 고삼은 $NF-{\kappa}B$ (p65)의 조절을 통하여 항알레르기 효과를 나타내었는데 이는 $I{\kappa}B-{\alpha}$ 저해의 억제와 항염증 시토카인 발현 억제와도 관계가 있다는 내용이다. Sophora flavescens, as a traditional herbal medicine, has been used to treat with a variety of disesases, In previous reports, S. flavescens and sophoraflavanone G (a prenylated flavonoid from S. flavescens) inhibited cytokines productions in LPS-induced Raw 264.7 macrophages cells and BV2 microglial cells. We examined on the anti-allergic effect of S. flavescens on the PMA plus A23187-induced rat leukemia (RBL-2H3) cells. S. flavescens inhibited the release of $\beta$-hexosaminidase and productions and expressions of tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-4 and cyclooxygenase (COX)-2 in a dose-dependent manner on stimulated RBL-2H3 cells, however, S. flavescens not affect cell viability. The protein expression level of nuclear factor (NF)-${\kappa}B$ (p65) was decreased in the nucleus and suppressed the degradation of inhibitory protein $I{\kappa}B-{\alpha}$ protein, the activation of extracellular signal-regulated kinases (ERK) mitogen-activated protein kinase (MAPK) by S. flavescens. These results suggest that S. flavescens could be involved anti-allergic effect by control of $NF-{\kappa}B$ (p65) translocation into the nucleus through inhibition of $I{\kappa}B-{\alpha}$ degradation and suppression of pro-inflammatory cytokines expression.
On Antenna Orientation for Inter-Cell Interference Coordination in Cellular Network MIMO Systems
Jeng-Shin Sheu,Shin-Hong Lyu,Chuan-Yuan Huang 한국통신학회 2016 Journal of communications and networks Vol.18 No.4
Next-generation (4G) systems are designed to supportuniversal frequency reuse (UFR) to achieve best use of valuablespectra. However, it leads to undesirable interference level nearcell borders. To control this, 4G systems adopt techniques, suchas network multiple-input multiple-output (MIMO) and inter-cellinterference coordination (ICIC), to improve cell-edge throughput. Network MIMO aims at mitigating inter-cell interference towardscell-edge users (CEUs) through multi-cell cooperation, where eachcollaborative base station serves both cell-center users (CCUs) andCEUs, including other cells’ CEUs, under a power constraint. The present ICIC strategies cannot be directly applied to networkMIMO because they were designed in absence of multi-cell coordination. In the presence of network MIMO, this paper investigatesantenna orientations in ICIC and the method of power management. Results show that a proper antenna orientation can improvethe cell-edge capacity and meantime lower the interferenceto CCUs. Capacity inconsistency between CCUs and CEUs is detrimentaltomobile communications. Simulation results show that theproposed power management for ICIC in network MIMO systemscan achieve a uniform data rate regardless users’ position.

In order to protect human lives from disease, various biosensors having the potential to analyze a variety of biomolecules have been utilized. Biosensors constitute one of the most promising ways to monitor and detect various biomolecules corresponding to diseases. In this study, we demonstrate that the reaction of streptavidin molecules with biotin on a gold electrode can be detected using the twoelectrode method with a gold electrode and a platinum reference electrode. We also show the characteristics of the electrical current response. While detecting 2-μM streptavidin molecules dissolved in phosphate buffered saline(PBS) solution, we found that an analytical biosensor can operate on the principle of detecting an antigen-antibody reaction event of protein molecules using the two-electrode method. We think that the "potential step" method might be useful to detect the occurrence of any antigen-antibody reactions and can be combined with other devices or ICs such as BJTs, MOSFETs, and OP-amps for the detection of biomolecules of diseases.

The Korean Society of Neurogastroenterology and Motility first published guidelines for chronic constipation in 2005 and was updated in 2011. Although the guidelines were updated using evidence-based process, they lacked multidisciplinary participation and did not include a diagnostic approach for chronic constipation. This article includes guidelines for diagnosis and treatment of chronic constipation to realistically fit the situation in Korea and to be applicable to clinical practice. The guideline development was based upon the adaptation method because research evidence was limited in Korea, and an organized multidisciplinary group carried out systematical literature review and series of evidence-based evaluations. Six guidelines were selected using the Appraisal of Guidelines for Research & Evaluation (AGREE) II process. A total 37 recommendations were adopted, including 4 concerning the definition and risk factors of chronic constipation, 8 regarding diagnoses, and 25 regarding treatments. The guidelines are intended to help primary physicians and general health professionals in clinical practice in Korea, to provide the principles of medical treatment to medical students, residents, and other healthcare professionals, and to help patients for choosing medical services based on the information. These guidelines will be updated and revised periodically to reflect new diagnostic and therapeutic methods. (J Neurogastroenterol Motil 2016;22:383-411)
