Severe maternal morbidity is frequently associated with catastrophic complications of pregnancy such as amniotic fluid embolism (AFE) or sepsis due to chorioamnionitis. The authors report a case of postpartum maternal hypoxic encephalopathy that might be attributed to AFE or sepsis due to chorioamnionitis with Escherichia coli bacteremia, and review the relevant literature. The patient presented with preterm labor, underwent Cesarean section for intrauterine fetal demise, and experienced postpartum cardiopulmonary collapse and disseminated intravascular coagulation, which led to catastrophic postpartum maternal encephalopathy.

Objectives : Seungmagalgeun-tang (SMGGT) is traditional medicine widely used for inflammatory disease and flu. But SMGGT exhibits potent anti-inflammatory activity with an unknown mechanism. To elucidate the molecular mechanisms of SMGGT water extract on pharmacological and biochemical actions in inflammation, we examined the effect of SMGGT on pro-inflammatory mediators in Phorbol-12-myristate-13-acetate (PMA)+A23187 -stimulated mast cells. Methods : In the present study, pro-inflammatory cytokine production was determined by performing enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western blot analysis to measure the activation of MAPKs. Cells were treated with SMGGT 1 h prior to the addition of 50 nM of PMA and 1 μM of A23187. Cell viability was measured by MTS assay. The investigation focused on whether SMGGT inhibited the expressions of interleukin-6 (IL-6), interleukin-8 (IL-8) and mitogen-activated protein kinases (MAPKs) in PMA+A23187 -stimulated mast cells. Results : SMGGT has no cytotoxicity at examined concentration (100, 250, and 500 μg/ml). Also, gene expression of IL-6 and IL-8 in HMC-1 cells stimulated by PMA+A23187 was down regulated by SMGGT. Furthermore, SMGGT suppressed the PMA+A23187-induced phosphorylation of extracellular signal-regulated kinase (ERK) and c-jun N-terminal Kinase(JNK). But, SMGGT could not regulate phosphorylation of p38 MAPK. Conclusions : These results suggest that SMGGT has inhibitory effects on PMA+A23187-induced IL-6 and IL-8 production. These inhibitory effects occur through blockades on the phosphorylation of ERK and JNK.

In recent years there has been a growing body of literature within public administration and political sciences that directly and indirectly uses, discusses and analyzes the processes involved in lesson-drawing, policy convergence, policy diffusion and policy transfer. While the methodology and focus often vary, all of these studies are concerned with a process in which knowledge about policies, administrative arrangements, institutions and ideas in one political setting is used in the development of policies, administrative arrangements, institutions and ideas in another political setting. The concept of policy transfer have become increasingly influential ways of understanding public policy. I tried to suggest the theoretical framework to analyze the role of policy transfer in policy making process. This article is divided into four major sections. The first section briefly considers the concept of, the research trend of policy transfer. The second section then presents a framework for the analysis of policy transfer. The third section outlines the limits of policy transfer itself and the framework of this paper. Finally, the last section addresses the future research agenda of policy transfer.

The purpose of this study is to suggest the proposals for enhancing the effectiveness of the response activities of emergency response organizations which must make prompt and successive decisions in urgent situation. For this research we have analyzed the emergency management case of the fire in Daegu subway, which occurred in February 2003, causing hundreds of casualties. The four main functions of response organizations were rescue operation, emergency medical care, information management and preparedness. The results of the analysis indicate that the problems of emergency management during the subway fire were as follows: 'little understanding of the disaster', 'defects of disaster management system', 'unorganized unified command system', and 'insufficient experience of emergency response organization'. The case study also suggests some policy implications to solve these problems, which are 'improvement of individual safety capability', 'reinforcement of systematic cooperation system', 'establishment of support system of emergency response organization'.
국어교사의 쓰기평가 신뢰도에 영향을 미치는 인지 과정 특성 분석

이 연구의 목적은 국어교사의 쓰기평가 인지 과정을 분석하여, 평가자의 신뢰도에 영향을 미치는 인지 과정의 특성을 탐색하는 데 있다. 이를 위해 국어교사 7명이 학생 글 20편을 평가한 과정을 촬영한 비디오 영상을 바탕으로 평가 시간과 회귀 빈도를 지표로 쓰기평가 인지 과정을 분석하였으며 평가 결과에 대한 평가자의 신뢰도를 측정하였다. 먼저 20편의 학생 글에 대한 쓰기평가 총 소요 시간은 1491초에서 6016초까지 다양하게 나타났으며, 평가자 신뢰도가 낮은 경우 쓰기 과제와 쓰기평가 기준을 이해하는 데 인지 부담이 큰 것으로 나타났다. 쓰기평가의 인지 과정을 각 단계별로 살펴본 결과, 쓰기평가 기준을 표상화하는 2단계에서 평균 7.57편을 평가한 이후, 평가 시간이 짧아지면서 인지부담이 줄어드는 것으로 나타났다. 또한 일관성이 과적합이나 부적합한 경우에는 2단계에서 더 많은 학생 글을 적용해 보아야 하는 것으로 나타났다. 다음으로 쓰기평가 인지 과정에서의 상위인지를 포착하기 위해 회귀 빈도를 살펴본 결과, 평가자별 회귀 빈도는 2회에서 23회까지 폭넓게 나타났다. 또한 쓰기평가 인지 과정에서의 회귀 빈도로 관찰된 상위인지의 활성화는 평가자 간 신뢰도와 평가자 내 신뢰도 모두에 영향을 미치는 것으로 나타났다. The purpose of this study is to analyze the writing assessment cognition process of Korean language teachers and explore the characteristics of cognition processes that affect the reliability of raters. To this end, videos of seven Korean language teachers evaluating 20 student writings were filmed as data. Based on these videos, the writing assessment recognition process was analyzed based on the time spent on the assessment and the frequency of regression, and the rater's reliability in the assessment results was measured. First of all, the total time required for writing assessment for 20 student writings differed greatly from 1,491 seconds to 6016 seconds, and if the rater's reliability is low, the cognitive burden is high to understand the writing task and writing assessment criteria. Looking at the cognition process of writing assessment at each stage, it was found that after an average of 7.57 episodes were evaluated in the second stage of presenting the writing assessment criteria, the cognitive burden was reduced as the assessment time was shortened. In addition, if the consistency of the rater is over-fitting or mis-fitting more student writing should be applied in the second phase. The frequency of regression per rater reviewed to capture meta-cognition in the writing assessment cognition process varied from 2 to 23. Also it is analyzed that activation of meta-cognition observed by regression frequency affects both inter-rater and intra-rater reliability.
