The objective of this study was to investigate mineral precipitates, which derived from the zero valent iron (ZVI) corrosion during TCE dechlorination and to find the controlling factors in mineral precipitates. A series of column experiemnts were conducted to evaluate the location of ZVI and the effects of electrode arrangements in electro-enhanced permeable reactive barrier (E2PRB) systems. Based on mineralogical study, ZVI samples near the influent port had more lepidocrocite, ferrihydrite or Fe (oxy)hydroxide, and (phospho)siderite while backward samples had more akaganeite, magnetite/maghemite, and intermediate green rust (GR) I and GR II. A suite of mineral distribution was preferabley related to the dissolved oxygen and the increased pH. Controlling factors of mineral precipitates in an E2PRB system were found to be (1) pH, (2) dissolved oxygen, (3) the types of Fe intermediates, and (4) anionic species to form complex strongly. 본 연구는 0가 철 (ZVI)의 설치위치와 전극의 배열에 따른 다양한 조합의 전기적 투수성 반응벽을 대상으로 트리클로로에틸렌의 탈염소화 반응에 의한 정화시 ZVI의 부식에 기인하는 광물상 침전물에 대해 알아보고, 이에 대한 조절 요소를 알아보고자 한다. 광물학적 연구 결과, 지하수 유입부의 ZVI 시료는 상대적으로 많은 레피도크로사이트, 훼리하이드라이트 혹은 철 수산화물과 (phospho)siderite가 산출되는 반면, 용출부의 ZVI 시료는 아카가나이트, 자철석/마그헤마이트, 그리고 중간 산물인 green rust (GR) I 과 GR II가 산출되었다. 이러한 광물 조합의 변화는 용존 산소 및 pH의 상승에 주로 기인한 것으로 나타났다. 또한 전기적 투수성 반응벽 내에 산출되는 광물상 침전물들의 조절 요소들은 (1) pH, (2) 용존산소, (3) 철의 부식시 중간 산물, (4) 음이온 종류 등으로 밝혀졌다.

Lazarus sign, a complex reflex movement of the upper limbs after brain death, is a rare occurrence. We report two patientswho showed a Lazarus sign following a diagnosis of brain death. It has been accepted that cardiac arrest usually occurswithin 1 week after brain death; however, the two patients described herein survived for over 100 days after brain death wasdiagnosed. This report is intended to examine the relationship between the Lazarus sign and long-term survival after braindeath, as well as to share our rare experience.

문지원,현동근 대한신경손상학회 2017 Korean Journal of Neurotrauma Vol.13 No.1
The importance of treating traumatic brain injury (TBI) is well known worldwide. Although many studies have been conducted in this topic, there is still much uncertainty about the effectiveness of surgical treatment in TBI. Recently, goodrandomized controlled trial (RCT) papers about the effectiveness of decompressive craniectomy (DC) in TBI has been published. In this article, we will review the overall contents of the DC (historical base, surgical technic, rationale, complications) and the results of the recently published RCT paper.

As the demand for Gongnyeo(women as tributes) began in earnest during the interference period, the female position within the ruling class faced a threat of lowering. However, it is difficult to say that the status of women who went to Gongnyeo or Goryeo women during the original interference period has been weakened collectively. This is because there are cases where women who have risen to the status of empress have risen to a position where they can exert great influence. In some cases, daughters were sacrificed for the benefit of themselves and their families, but there are various aspects to avoid the Goryeo Dynasty's transfer of Gongnyeo. Examples include avoiding, obtaining a preface, or discussing polygamy. Among the Gongnyeo who went to the Yuan, the figures related to Dokrohwa were Empress Dalmasili and Empress Baekanholdok. These were the daughters of a prestigious family in Goryeo, the Empress of Woninjong. On the other hand, Empress Ki's family was not the representative Goryeo royal family, nor was it a politically or socially influential family. Empress Ki's family and relatives believed in Empress Ki's power and showed arrogance and tyranny. In order to maintain the power of herself, a former Gongnyeo, and the crown prince, she directly manages and uses the Gongnyeo to establish his political position. Eventually, the three empresses who went from Goryeo to Yuan were transferred to the highest rank as Gongnyeo, but their attempts to use them politically resulted in different results. In addition, the rise in their status resulted in more recruitment of Gongnyeos, and changes in the marriage system to avoid this became the starting point for changes in women's status and social changes in the late Goryeo Dynasty. 원 간섭기에 공녀 요구가 본격화되면서 지배층 내에서 여성 지위는 하향되는 위협을 맞이하였다. 하지만 공녀로 간 여성이나 원 간섭기 고려 여성의지위가 일괄적으로 약화되었다고 보기 힘들다. 황후의 지위에 오른 여성들처럼 막강한 영향력을 행사할 수 있는 지위에 오른 사례도 있기 때문이다. 자신과 가문의 이익을 위해 딸을 바치는 경우도 있었지만 고려 조정의 공녀 차출을 피하기 위한 양상은 다양하게 나타난다. 회피하거나, 豫壻를 얻거나 일부다처제에 대한 논의가 일어났던 것이 그 예이다. 원에 간 공녀 중 禿魯花와 관련 된 인물은 달마실리황후와 백안홀독황후이다. 이들은 원 인종의 황후로 고려 내에서도 명망있는 가문의 딸들이었다. 이에 반해 기황후의 가문은 고려 대표 가문인 고려 왕실도 아니었고 정치적, 사회적으로 유력한 가문도 아니었다. 기황후는 그의 가족과 친척들이 기황후 의 세력을 믿고 교만하고 횡포한 모습을 보였다. 공녀 출신인 자신과 황태자의 권력 유지를 위하여 자신의 정치적 입지를 세우기 위하여 공녀들을 직접관리하고 이용하는 모습을 보인다. 결국 고려에서 원으로 간 세 명의 황후는공녀로 차출되어 최고의 지위까지 올랐으나, 그녀들을 정치적으로 활용하려했던 시도는 각각 다른 결과를 낳았다. 또한 그녀들의 지위 상승은 더 많은공녀 차출을 낳았고, 이를 회피하기 위한 결혼제도의 변화는 고려 말기 여성지위 변화와 사회 변동의 시발점이 되었다.

Ethylene is the fundamental material of products such polyethylene (LDPE, HDPE), 1,2-dicholorenthane, ethanol, ethylene oxide. To produce ethylene, this research used ethane dehydrogenation and CO<sub>2</sub> activation. This research aims to effective oxidative dehydrogenation of ethane using MoVTeNbO with chemical looping. The chemical looping oxidative dehydrogenation (CL-ODH) is two step of the reaction. The first step is reaction of MoVTeNbO with ethane using lattice oxygen. The Second step injects lattice oxygen into the reduced catalyst as converting CO<sub>2</sub> into CO. The effect of MoVTeNbO is determined by various methods of analysis, such as H2-TPR, SEM, N2-Sorption and XRD.

The visual quality of landscape and view have been extensively studied in terms of an aesthetic value and a monetary asset. But other viewpoints such as the quality of the view at each apartment unit has been disregarded. Thus, in this paper, the characteristic of each view in an apartment unit was analyzed by means of the preference evaluation in order to deal with the view in terms of the quality. In the preference evaluation on the view at each apartment unit, the distance from a viewer to view targets was assumed all the same to each case, and representative view targets among diverse ones were accounted. In addition, the level in an apartment was partitioned into three groups ; low level, meddle level, and high level. Under these constraints, 33 cases were evaluated by 129 interviewees and then we found the valuable results from the 3 hypotheses as follows ; 1) A natural type view is more preferred than others(Hypothesis I). But the well-integrated view of a natural type and artificial type was the most preferred one by interviewees. 2) In the case of the same view target, view from a high level is more preferred than one from a low level(Hypothesis II). But the preference of the view target depends on the view characteristics of each level units. 3) The more natural views are, the more preferred view(Hypothesis III). But it was not directly related to the degree of the natural view.

생육실 내·외부 환경조건과 종균 배양 및 자실체 특성검 정 결과 다음과 같은 결론을 얻을 수 있었다. 먼저, 종균 배양이 외부 온도의 영향을 받는 것을 확인할 수 있었다. 배양실의 환경 조건(22oC, 65-68%, 700-1,200 ppm)을 일 정하게 하여도 외부 기온이 낮고, 건조해지는 1월(동절기) 에는 16-18일 가량 늦은 것을 확인하였다. 또한, 외부 기후에 따라 생육실 내부 환경이 영향을 받 아, 자실체 생장이 느리고 발생 형태가 다른 것을 확인하 였다. 동일한 조건(18±1oC, 85-95%, 700-1,200ppm)을 설 정한 생육실에서 재배한 버섯이 수량(무게), 길이(크기) 모두 1월에 수확한 버섯이 3월에 수확한 버섯에 비해 작 은 수치임을 확인하였고, 경도가 작아 품질 면에서도 양 호하지 못함을 확인하였다. 이는 1월 외부의 영하의 저온 과 60% 이하의 저습에 의해 생육실 내부 환경이 변화하 여 일어난 현상임을 알 수 있었다. 아울러 버섯의 특성은 일정 시일이 지난 후 외부 기후를 보완하여 실내 환경을 조절하여도 개선되지 않음을 확인하였다. 일정 기간이 지 난 후의 조치는 균의 노후화만 진행시켜 색만 변화할 뿐 크기가 커지거나 침이 형성되지 않았다. 그러므로 환경 스트레스를 받지 않도록 미리 예방하는 것이 필요하다. 환기와 생육관리를 위해 생육실 내부 환경이 외부로 노출 될 때, 외부 환경이 영향을 미치지 않도록 에어커튼 혹은 보온 커튼을 덧대어 문제가 발생하지 않도록 해야할 것이다. 특히, 동절기와 같이 외부 기온이 낮고, 습도가 낮은 시기에는 특별히 주의가 필요할 것이다. In this study, we observed differences in the fruit body genesis in with seasonal changes. The mushrooms generated different spines even when under same environmental conditions in equivalent growth chambers during different seasons. The growth chamber conditions were set at 18°, 1000 ppm CO and 95% humidity for uniform primordium formation. Following this, the humidity was reduced to 85% during growth and development. The characteristics of the fruit body were measured: yield (weight), length (size), hardness, and chromaticity. Each measure was relatively compared owing standard data for . We investigated the environmental factors to assess the cause of variation in fruit body. Change in temperature and humidity were especially focused on, apart from climate that can affect mushroom growth. It was observed that temperature and humidity both influence fruit body growth. Not the absolute value of the elevation, there was a change of climate which the temperature is lowered and lowered the humidity can be assumed that the changes in the environmental conditions inside the growth chamber the mushroom growth.
