The distribution of coral reefs can be an indicator of environmental or anthropogenic impacts. Here, we present a habitat map of coral reefs developed using high-spatial satellite images. The study area was located on the north-eastern part of Weno island, in the Chuuk lagoon of Federated States of Micronesia. Two fieldwork expeditions were carried out between 2007 and 2008 to acquire optical and environmental data from 121 stations. We used an IKONOS image obtained in December 2000, and a Kompsat-2 image obtained in September 2008 for the purpose of coral reef mapping. We employed an adapted version of the object-based classification method for efficient classification of the high-spatial satellite images. The habitat map generated using Kompsat-2 was 72.22% accurate in terms of comparative analysis with in-situ measurements. The result of change detection analysis between 2000 and 2008 showed that coral reef distribution had decreased by 6.27% while seagrass meadows had increased by 8.0%.

이 연구의 목적은 민간경비원의 사건충격과 직무스트레스 및 대처능력의 관계를 규명하는데 있다. 이 연구는 2011년 인천소재 공항에서 재직하고 있는 민간경비원들을 모집단으로 설정한 후 판단표집법을 이용하여 최종분석에 이용된 사례 수는 총 239명이다. 연구에 사용된 설문지는 총 67문항으로 구성되었으며, SPSSWIN 18.0을 이용하여 빈도분석, 요인분석, 신뢰도분석, 회귀분석 등을 실시하였다. 설문지의 신뢰도는 Cronbach's ${\alpha}$값이 .779이상으로 나타났다. 결론은 다음과 같다. 첫째, 민간경비원의 사건충격은 직무스트레스에 영향을 미친다. 즉, 침습이 자주 반복될수록 인간관계에 대한 스트레스는 증가한다. 또한, 과각성이 자주 반복될수록 역할에 대한 스트레스는 증가한다. 둘째, 민간경비원의 사건충격은 대처능력에 영향을 미친다. 즉, 과각성이 자주 반복될수록 문제중심적 대처능력은 감소한다. 반면, 회피성향이 지속적으로 작용할수록 문제중심적 대처능력은 증가한다. 셋째, 민간경비원의 직무스트레스는 대처능력에 영향을 미친다. 즉, 직무특성에 대한 무력감이 작용할수록 문제중심적 대처능력은 증가한다. 반면, 역할에 대한 모호성이 높게 작용할수록 문제중심적 대처능력, 사회적지지 추구능력은 감소한다.

The conversion of carbon dioxide to value-added compounds has been attracted to solve the environmental problems due to the climate change caused by greenhouse effect in addition to recycle the abundant and renewable carbon source. For utilizing carbon dioxide to useful compounds, the development of catalysts and optimization of experimental conditions are indispensable since carbon dioxide is the most stable one among carbon compounds and the a certain amount of energy is required for the carbon dioxide conversion. The technologies developed for the electrochemical carbon dioxide conversion were reviewed in terms of electrocatalyst which can be electrode material, inorganic complex, and enzyme. This field should be developed further since no good catalyst having selectivity, efficiency, and stability all together.

Through a literal study upon the cause of epilepsy between east and west medicine, next conclusion have been abtained. 1. The cause epilepsy in the east medicine, congenital embryo disease is due to insufficiency of heart(心虛) or deficiency of heart energy(心氣虛), secondary cause is wind -evil(風), frightness(驚), phlegm(痰), fire(火) 2. The cause epilepsy in the west medicine is divided congenital disease and secondary cause, one is excessive discharge of electricity of the brain have on a central nerve, a digestive organ, a respiratory organ, hamatogenous functions, the other is hereditary it and pathological it. 3. The epilepsy is concerned about the abnormality in five viscera, liver, spleen, heart. 4. In comparison east and west medicine of epilepsy is native factor, or innate primary cause is added to outer cause of wind-evil(風), cold-evil(寒), summer-heat(署), wetness(濕), and inner cause of frightness-terror(驚-恐), seven modes of emotions(七情) and the epilepsy is occurred phlegm(痰), fire(火). It similar that the epilepsy is occurred to structural and functional obstacle in western hereditary and primary cause.

Reye syndrome is a rapidly progressive encephalopathy with hepatic dysfunction, which often begins several days after apparent recovery from a viral illness, especially varicella or influenza A or B. Salicylate use was identified as a major precipitating factor for the development of Reye syndrome. With the recommendation to avoid use of salicylates in children, Reye syndrome has virtually disappeared in recent years. We report a case of Reye syndrome in a 5-month-old infant who had been treated with intravenous immunoglobulin and aspirin under the diagnosis of Kawasaki disease, and showed symptoms of sudden onset of irritability, rigidity, decreased activity, vomiting, poor appetite, lethargy, liver dysfunction without jaundice, coagulopathy, and hyperammonemia.

그래핀(graphene)은 모든 탄소 원자가 표면에 존재하는 이차원 결정이기 때문에 다른 고체 표면에 고착될 때 인장 및 압축 변형(tensile & compressive strain)과 전하 도핑(charge doping)에 취약하다고 알려져 있다. 본 연구에서는 산화실리콘(SiO2/Si) 기판 위에 기계적으로 박리된 그래핀에 혼재되어 나타나는 기계적 변형과 전하 도핑 현상을 분석할 수 있는 라만 분광법 기술을 개발하고자 하였다. 대부분의 시료에서 기계적 변형으로 인해 라만 G-band와 2D-band의 진동수(${\omega}$)가 특별한 상관관계(${\Delta}{\omega}2D/{\Delta}{\omega}G$ = 2.0 ${\pm}$ 0.2)를 가진다는 사실을 확인하였다. 전자 친화도가 큰 F4-TCNQ (tetrafluorotetracianoquinodimethane)를 증착하여 화학적으로 p-형 전하 도핑을 유도한 그래핀에서는 기계적 변형과는 분명히 구별되는 상관관계(${\Delta}{\omega}2D/{\Delta}{\omega}G$ = 1.0 ${\pm}$ 0.3)가 관찰되었다. 본 연구는 라만 분광법을 통해 그래핀의 기계적 변형과 전하 도핑 정도를 정량적으로 분리해서 분석할 수 있는 방법을 제시해 준다.

Contamination of explosive compounds in the soils of military shooting range may pose risks to human and ecosystems. As shooting ranges are located at remote places, active remediation processes with hardwares and equipments are less practical to implement than natural solutions such as bioremediaton. In this study, a series of experiments was conducted to select a suitable carbon source and to optimize dosing rate for the enhanced bioremediation of explosive compounds in surface soils and sediments of shooting ranges with indigenous microorganisms activated by external carbon source. Treatability study using slurry phase reactors showed that the presence of indigenous microbial community capable of explosive compounds degradation in the shooting range soils, and starch was a more effective carbon source than glucose and acetic acid in the removal of TNT. However, at higher starch/soil ratio, i.e., 2.0, the acute toxicity of the liquid phase increased possibly due to transformation products of TNT. RDX degradation by indigenous microorganisms was also stimulated by the addition of starch but the acute toxicity of the liquid phase decreased with the increase of starch/soil ratio. Taken together, the optimum range of starch/soil ratio for the degradation of explosive compounds without significant increase in acute toxicity was found to be 0.2 of starch/soil.

To examine different types of influenza diagnostic test kits automatically, automated rapid influenza diagnostic test method based on image recognition is proposed in this paper. First, the proposed methods classify a variety of the rapid influenza diagnostic test kit based on support vector machine that analyzes the kits' feature point. Then, to improve the accuracy of test, the proposed methods match the histogram of both the target image of influenza kit and the input image of influenza kit for minimizing the effect of environment factors, such as lighting and exposure variations. And, to minimize the effect from composition of the hand-helds devices, the proposed methods extract the feature point and match point-by-point between target image of influenza kit and input image of influenza kit. Experimental results of 124 experimental group show that the proposed methods significantly have effectiveness, which shows 90% accuracy in moderate antigen, for the preliminary examination of influenza, and provides the opportunity for taking action against influenza.
