본 연구는 중등교사의 논쟁학습 실천 지향성에 따른 논쟁학습 실천 장애 인식이 어떠한지를 탐구하여 논쟁학습 중심 민주시민교육을 현장에 적용하기 위한 토대를 마련하고자 한다. ‘보이텔스 바흐 합의’의 내용이 논쟁학습의 실천 원리와 정합한다는 점에 주목하여, 서울특별시교육청교육연 구정보원과 서울교육정책연구소(2017)에서 위탁받아 시행된 ｢보이텔스바흐 합의 정신에 기반한 학교 시민교육 현장 적용 방안 연구｣에서 수집된 자료를 이차분석(secondary analysis)하였다. ‘보이텔스바흐 합의’의 핵심 내용에 대한 지지 정도에 기반한 논쟁학습 실천 지향성을 분류하여, 조사 대상자는 ‘적극적/보통/소극적’ 논쟁학습 실천 지향성 집단으로 범주화되었다. 일원분산 분석한 결과는 다음과 같다. 첫째, 소극적 실천 지향성 집단일수록 논쟁학습 내용이 교육과정과 교재 내용과의 부합성을 부정적으로 인식하며 논쟁학습의 실천을 교사의 정치적 중립 의무 위배 가능성으로 인식하는 경향성이 뚜렷하게 나타났다. 둘째, 적극적 실천 지향성 집단일수록 논쟁학습 실행에 대한 제도적 제한뿐만 아니라 교사 신변의 불안정성을 뚜렷하게 인식하고 있는데, 이는 외적 장애에 민감하다는 것을 의미한다. 또한, 적극적 실천 지향성 집단이 논쟁학습에 대하여 부분적인 교수효 능감을 인식하였다. 본 연구는 조사대상이 서울시 중등 교사에 한정되어 있으나 논쟁학습의 실행 지향성 수준에 따른 논쟁학습 장애에 대한 교사의 인식 양태가 서로 다르게 나타나므로 향후 민주 시민교육 실천 확대를 위한 방안도 이에 따라 서로 차별화될 필요가 있다.

This study is to identify the heat vulnerability area as represented by heat risk factors which could be attributable to heat-related deaths. The heat risk factors were temperature, Older Adults(OA), Economic Disadvantage(ED), Accessibility of Medical Services(AMS), The population Single Person Households(SPH). The factors are follow as; the temperature means to the number of days for decades average daily maximum temperature above 31℃, the Older Adults means to population ages 65 and above, furthermore, the Economic Disadvantage means to the population of Basic Livelihood Security Recipients(BLSR), the Accessibility of Medical Services(AMS) means to 5 minutes away from emergency medical services. The results of the analysis are showed that the top-level of temperature vulnerability areas is Dong, the top-level of vulnerability OA areas is Eup, the top-level of AMS vulnerability is Eup. Moreover, the top-level of vulnerability ED area appears in the Eup and Dong. The result of analysing relative importance to each element, most of the Eup were vulnerable to heat. Since, there are many vulnerable groups such as Economic Disadvantage, Older Adults in the Eup. We can be figured out estimated the number of heat-related deaths was high in the Eup and Dong by the data of emergency activation in the Chungcheongnam-do Fire Department. Therefore, the result of this study could be reasonable.

Background : The geographical origin of Panax ginseng Meyer, a valuable medicinal plant, is important to both ginseng producers and consumers in the context of economic profit and human health benefits. We therefore aimed to discriminate between the cultivation regions of ginseng using the stable isotope ratios of C, N, O, and S, which are abundant bio-elements in living organisms. Methods and Results : The C, N, O, and S stable isotope ratios were measured by isotope ratio mass spectrometer, and then these isotope ratios profiling was statistically analyzed with chemometrics. The various isotope ratios found in Panax ginseng roots were significantly influenced by region, cultivar, and the interactions between these two factors (P ≤ 0.0002). In particular, δ18O was lower in ginseng roots grown at high altitudes (r = −0.47), while δ34S was higher in ginseng roots grown close to coastal areas (r = −0.48). Chemometric results provided discrimination between the majorities of different cultivation regions. Conclusion : Our case study extends the understanding about the variation of C, N, O, and S stable isotope ratios in ginseng root depending on cultivation region. Hence, the analysis of stable isotope ratios is a suitable tool for discrimination between the regional origins of ginseng samples from Korea, with potential application to other countries.

Background : Undulatum Rhubarb, commonly produced in domestic, is rhizome of Rheum undulatum L. that belongs to the family Polygonaceae. It also can be used as a substitute of R. palmatum L., R. tanguticum Maximowicz ex Balf., and R. officinale Baillon which completely depend on import system. However, there should be clear clarification among Undulatum Rhubarb and Rhubarb, because Undulatum Rhubarb contains rhaponticin as marker compound that is not indicated at Rhubarb. Some of the recently imported Undulatum Rhubarbs have been found to be Rhubarb. Also, it is known that only Undulatum Rhubarb is cultivated at domestic environment. But some plant origins of Rhubarb are grown in Korea, too. Further study are needed to clarify clear origin between Undulatum Rhubarb and Rhubarb. Thus, we collected some domestically cultivated samples and identified them. Methods and Reseults : Rheum undulatum L., Rhubarb, Rheum tanguticum Maximowicz ex Balf. which were cultivated in Gangwondo Agricultural Research and Extension Services in Cheorwon were collected and anayzed the DNA sequences. We also compared DNA sequences in Rhubarb collected from England and R. rhabarbarum L., R. undulatum L., and R. franzenbachii on NCBI. As a result, two kinds of rhubarb cultivated in the test plantation were identified as R. rhabarbarum and R. officinale. In addition, R. undulatum (plant origin of Undulatum Rhubarb) was identified as Rhubarb (Rheum rhabarbarum) in England with 99 - 100% identical in nuclear ITS gene region. Conclusion : R. undulatum, plant origin of Undulatum Rhubarb, is reported as synonym of R. rhabarbarum, R. franzenbachii. Rheum speices which are cultivated as tester in Gangwondo Agricultural Research and Extension Services in Cheorwon are estimated as R. undulatum and R. officinale. Therefore, not only Undulatum Rhubarb but Rhubarb could be grown in Korea.

Background : Corrosion is one of the most devastating problems faced by most industries. Mild steel has played a vital role in various fields due to the excellent mechanical properties of mild steel such as low density, high strength-to-weight ratios, good environmental stability, high thermal conductivity, and corrosion resistance. Methods and Results : The total phenolic contents (TPC) and total flavonoid contents (TFC) of the methanolic extract of C. grandiflora and R. verniciflua leaf have been examined, and its corrosion inhibition performance was investigated by weight loss and electrochemical impedance spectroscopy (EIS) and polarization measurements. The surface morphology of mild steel was analyzed by scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDX) and by atomic force microscopy (AFM). The percentage composition of polyphenolic compounds was found to be higher in C. grandiflora and R. verniciflua plant extracts, and it was proved to be a superior, eco-friendly, and anti-corrosive inhibitor for mild steel in 1M of H2SO4. The Tafel polarization studies indicate that the plant extract is a mixed-type inhibitor. Scanning electron microscopy/energy -dispersive X-ray spectroscopy (SEM-EDS), and atomic force microscopy (AFM) studies confirmed the formation of a protective film on the metal surface. The corrosion inhibition of the C. grandiflora and R. verniciflua plant extracts was characterized by Fourier transform infrared (FT-IR), UV-visible spectra, and wide-angle X-ray diffraction (XRD) studies; these show the strong interaction between the metal surface and the inhibitor. Conclusion : The methanolic extract was prepared the two different plants like C. grandiflora, and R. verniciflua was studied the corrosion inhibition on the mild steel specimen in acidic medium through various methods involving weight loss measurements, EIS, and potentiodynamic polarization. The results shows that the C. grandiflora, and R. verniciflua plant extracts illustrate an effective corrosion inhibitor for mild steel with good anticorrosion properties in acidic environmen

Acinetobacter baumannii is one of the most problematic causative agents of nosocomial infections, especially in the immune compromised or patients in intensive care units. In recent years, as multiple antibiotic resistant A. baumannii has increasingly emerged, it has become difficult to treat infections effectively. The authors report a case of extreme drug resistant A. baumannii bacteremia caused by catheter-related infection, as confirmed by blood and catheter tip culture, in a 63-year-old man. The patient responded well to 24 days of doripenem and colistin treatment.

Background : The natural stable isotope ratio of common bio-elements like carbon (C), nitrogen (N), oxygen (O), or sulfur (S) varies with diverse isotope fractionation processes in nature. Therefore, measuring the variation of these stable isotope ratios in ginseng roots can be a feasible tool to discriminate the geographical origins of ginseng in Korea. Methods and Results : The 3-year-old six Korean ginseng cultivars were cultivated at the five regions in Korea, and then used for measuring the stable isotope ratios of C, N, O, and S by isotope ratio mass spectrometry (IRMS). The mean C, N, O, and S stable isotope ratio values in the ginseng roots significantly differed according to the cultivation regions (p < 0.05). However, these isotope ratios in ginseng roots had relatively weak discriminative power against to the ginseng cultivars at each cultivation region. The interaction of the cultivation region and ginseng cultivar type also significantly affected to the C, N, O, and S stable isotope ratio in ginseng roots (p < 0.0001). The two-dimensional plots associated with the N stable isotope ratio can effectively separate the ginseng roots in Jinan compared to those in the other regions. The partial least squares-discriminant analysis showed more significant separation between ginseng geographical origins compared to the principal component analysis. Conclusion : Our findings improve our understanding of how the isotope composition of ginseng roots varies with respect to cultivation regions and cultivars, and suggest that the analysis of the stable isotope ratios combined with chemometrics can be used as a feasible tool to discriminate geographical origin of ginseng in Korea.

In reinforced concrete (RC) structures, concrete carbonation depth is an important criterion for the deterioration of durability of RC structures. Concrete carbonation is influenced by multiple factors such as chloride attack, crack, concrete compressive strength, etc. However, due to its complex mechanism, most previous studies considered only one or two deterioration factors to estimate the concrete carbonation depth. In this study, therefore, inspection data were collected from 8 buildings, and the Adaptive Neuro-Fuzzy Inference System (ANFIS) algorithm that estimates the concrete carbonation depth of RC structures has been proposed. The proposed ANFIS model provided good estimations on the carbonation depths.

Prognosis of the patients with lung cancer with lung-to-lung metastasis are known to be poor and frequently old aged persons with multiple nodules on imaging study abandon more invasive procedure including bronchoscopy and VATS (Videoassisted thoracoscopic surgery) to get tissue confirmation. Sjogren’s syndrome (SS) associated lung lesion mimicking lung cancer has a chance to have more favorable diseases including lymphoma. A 78-year-old woman with SS was admitted due to slowly progressive exertional dyspnea and multiple nodules on imaging study. She and her family gave up invasive diagnostic procedures at first due to old age but short term rapid change of dyspnea and nodules on chest CT brought out invasive procedures and diffuse large B-cell lymphoma was diagnosed. Dyspnea and nodules on imaging were improved after R-CHOP chemotherapy.

In recent years, meteorological disasters have frequently occurred in rural areas. As a result, there have been growing concerns over the protective measures needed. In order to avoid natural risks and damage, and to strengthen countermeasure to meteorological disasters, local governments needs to be prepared. Therefore, this paper seeks to prevent meteorological disasters through mapping of inundation vulnerability in agricultural land, Chungcheongnam-do. In doing so, this study were considered 5 variables (i.e. precipitation, region of altitude below 50m, region of slope gradient is below 10 degree, distance from river within less 50m) for creating vulnerability map. The precipitation was excluded in five variables. Since, the precipitation which include Daily maximum precipitation, 2-Daily maximum precipitation, summer precipitation was not any correlation among them. The results of analysing four variables, exclusive of precipitation, were showed that the agricultural lands where located in Dangjin, Buyeo, Hongseong and Asan were low correlation of inundation vulnerability by overlapping analysis. Moreover, The correlation analysis was showed low correlation between each factors and the annual average area of agricultural lands’ inundation, whereas, the correlation analysis which was overlapping each factor showed high correlation. In conclusion, in order to create reliable vulnerability map in agricultural lands, Chungcheongnam-do, it must be considered to overlap analysis of the four main factors such region of altitude below 50m, region of slope gradient is below 10 degree, distance from river within less 50m. We suppose that this study’s analysis can help to set the preparedness site of agricultural lands inundation.

Toxocariasis is an illness of humans caused by roundworm. Toxocara species are commonly found in dogs and cats. Humans are accidental hosts. There are two routes of infection. One route is the ingestion of infected eggs, and the other route is the ingestion of an infected paratenic host. Clinical manifestations vary from asymptomatic infection to severe organ failure. In most cases, the patients are asymptomatic and the disease is self-limited. Thus, patients with mild symptoms do not require treatment. However we report on cases of patients with asymptomatic hepatic nodules who were treated to exclude malig-nant disease.

The necessity of climate change adaptation has steadily increased due to the increasing meteorological disasters. The authority supports the vulnerability assessment tools for tuning the local governments’ countermeasure. However, the results by the vulnerability assessment tools have not been clear enough. The current study aims to collect and analyse a variety of raw data for proving the unclear assessments. The paper identifies climate change-vulnerable areas by overlapping the modified results and pervious results. The climate change-vulnerable areas included the regions having high impacts on meteorological disasters. In a nutshell, the paper contributes to the identification of the vulnerable areas for the local government’s planning the provision against climate change. The local governments are obliged to establish the climate change action plan by 2015. The results of the current paper would help providing reliable data and planning the countermeasure against climate change. Korea is exposed to the climate change vulnerability such as increasing elderly population, high density of urban areas. In order to respond the climate change vulnerability efficiently, this study potentially suggests a primary research method for resolving the climate change vulnerability.

Since greenhouse gas emissions increase continuously, the authorities have needed climate change countermeasure for adapting the acceleration of climate change damages. According to "Framework Act on Low Carbon, Green Growth", Korean local governments should have established the implementation plan of climate change adaptation. These guidelines which is the implementation plan of climate change adaptation should be established countermeasure in 7 fields such as Health, Digester/Catastrophe, Agriculture, Forest, Ecosystem, Water Management and Marine/Fisheries. Basically the Korean local governments expose vulnerable financial condition, therefore the authorities might be assessed the vulnerability by local regions and fields, in order to establish an efficient implementation plan of climate change adaptation. Based on this concepts, this research used 3 methods which are LCCGIS, questionnaire survey analysis and analysis of existing data for the multiphasic vulnerable assessment. This study was verified the correlation among 7 elements of climate change vulnerability by 3 analysis methods, in order to respond climate change vulnerability in rural areas, Seocheon-gun. If the regions were evaluated as a vulnerable area by two or more evaluation methods in the results of 3 methods' comparison and evaluation, those areas were selected by vulnerable area. As a result, the vulnerable area of heavy rain and flood was Janghang-eup and Maseo-myeon, the vulnerable area of typhoon was Janghang-eup, Masan-myeon and Seo-myeon. 3 regions (i.e. Janghang-eup, Biin-myeon, Seo-myeon) were vulnerable to coastal flooding, moreover Masan-myeon, Pangyo-myeon and Biin-myeon exposed to vulnerability of landslide. In addition, Pangyo-myeon, Biin-myeon and Masan-myeon was evaluated vulnerable to forest fire, as well as the 3 sites; Masan-myeon, Masan-myeon and Pangyo-myeon was identified vulnerable to ecosystem. Lastly, 3 regions (i.e. Janghang-eup, Masan-myeon and Masan-myeon) showed vulnerable to flood control, additionally Janghang-eup and Seo-myeon was vulnerable to water supply. However, all region was evaluated vulnerable to water quality separately. In a nutshell this paper aims at deriving regions which expose climate change vulnerabilities by multiphasic vulnerable assessment of climate change, and comparing-evaluating the assessments.

Owing to increase of meteorological disasters by climate change, it needs to study of climate change which will be able to deal with adaption for basic local authorities. A case study area of Yesan have been impacted by land-use which alter natural environment demage. It has led to micro-climate change impacts in rural area, Yesan. In order to adapt to the effects, this paper estimated temperature change in productivity of fruits and conducted decline of nonpoint pollutant loadings. As the results of temperature change of effecting on growth of apple, since a rise in temperature have not increased high, therefore the apple productivity could not be influence until 2030s. While the apple productivity could be declined 14.8% in 2060s. In addition, it supposes that the productivity would be decreased 44.5% in 2090s. Furthermore, it showed that the apple maturity has become worse, because length of high temperature has dramatic increased 54.2% in 2030s, 103.2% in 2060s and 154.0% in 2060s beside 2000, respectively, compared with 2000. As results of analysing between the future rainfall characteristics and nonpoint pollutant loadings, the subject of reduction of nonpoint pollutant was efficiency when it implemented around Oga-myeon or Deoksan-myeon Dun-ri. This study classified the region more detail each Eup and Myeon after that it analysed the rural region impacts of climate change for basic local authorities. Hence, this study is able to predict adaptation of rural region impacts of climate change. Due to increase of green house gases emission, meteorological disasters could often occur in the future. Therefore, it needs follow-up studies that assess climate change of effecting on rural region.
