고등학교 사회과 다문화 수업 프로그램이 학생들의 간문화적 태도에 미치는 영향 연구
조대훈(Daehoon Jho),이주영(Jooyoung Lee) 성신여자대학교 교육문제연구소 2011 교육연구 Vol.52 No.-
본 연구의 목적은 고등학교 방과후 다문화 수업 프로그램이 학생들의 다문화적 태도, 특히 간문화적 감수성(Intercultural Sensitivity)에 대해 가지는 영향을 분석하는 것이다. 이를 위해 연구자는 10시간 분량의 다문화 수업 프로그램을 설계하였다. 그리고 이 다문화 수업 프로그램을 다문화교육에 관심을 가진 서울 소재 사립 고등학교 사회과 교사의 도움을 얻어 개설한 ‘다문화사회 이야기’라는 방과 후 수업에 적용하였다. 연구자가 개발한 다문화 수업 프로그램이 학생들의 간문화적 태도에 변화를 가져왔는지 알아보기 위해 Hammer, Bennett & Wiseman(2003)의 ‘간문화적 발달 측정 척도(Intercultural Development Inventory, IDI)에 기초한 설문 조사를 실시하였다. 설문 자료 분석 결과, 본 연구에 포함된 간문화적 감수성의 하위 영역 4개 중에서 부정/방어(Denial/Defense), 최소화(Minimization) 및 수용/적응(Acceptance/Adaptation)의 3개 영역에서 통계적으로 유의미한 차이가 발견되었다. 이와 같은 결과는 연구자의 다문화 교육 수업 프로그램이 학생들의 다문화적 태도에 긍정적인 변화를 가져온다는 점을 보여줌과 동시에, 현행 사회과 교육과정에 적용가능한 다문화 교육과정의 내용과 방법의 개발에 긍정적인 시사점을 제공하고 있다. The purpose of this study is to examine the effects of the after-school multicultural lesson, “The Tales of A Multicultural Society” on students’ intercultural sensitivity. Based on the pedagogical model of multicultural education developed by Jho & Park (2009), “the Tales of A Multicultural Society” consisted of 10 instructional lessons (50 minutes per each) and was implemented in a local private girls’ high school in Seoul. The researchers monitored the entire lessons and conducted in-depth interviews with selective students. Then, in order to measure students’ intercultural attitudinal change, the Intercultural Development Inventory (IDI) survey of 50 items were administered to 40 students twice, on the first day of the course and 4 weeks after the completion of the course. In sum, the study found that overall the multicultural education course the researchers designed had a statistically positive impact on students’ intercultural sensitivity. The findings of the study request for further research and continuous investment on developing multicultural pedagogical knowledge and strategies.
Effect of co-presence of cadmium or procymidone with microplastic films in soil on lettuce growth

Agricultural environment is often contaminated with various chemicals (e.g., pesticides, heavy metals) and microplastics due to the uses of plastic products. The effects of chemical contaminants or microplastics on terrestrial environment have been extensively studied, but the studies on the co-presence of chemical contaminants and microplastics are relatively limited. This study was set to investigate the effect of co-presence of microplastics (i.e., low-density polyethylene (LDPE) and polyvinyl chloride (PVC) microplastic films) and chemical contaminants (i.e., cadmium (Cd) and procymidone (PCM)) in soil on the lettuce growth and Cd and PCM uptake by lettuce using pot tests. The lettuce leaf lengths were not affected by the presence of only Cd or PCM, but the rates of change in the lettuce leaf number were adversely affected by the presence of PCM. The presence of only LDPE or PVC in soil at the concentrations used in this study did not have significant impacts on the lettuce growth. But the co-presence of Cd and LDPE and the co-presence of PCM and PVC resulted in the negligible increases in the lettuce leaf length and leaf number with time, although the lettuce growths were statistically similar in the Cd- or PCM-contaminated soils regardless of the presence of microplastics. The results suggest that the adverse effects of Cd or PCM can be intensified by the co-presence of microplastics, and the effects can be different depending on the types of microplastics. The promoted adverse effects of chemical contaminants in the co-presence of microplastics can be supported by the tendency of the increased absorption of Cd or PCM by lettuce in the co-presence of microplastics. Overall, this study shows the need for management of both chemical contaminants and microplastics that may reside in the agricultural environment.

THEORETICAL REVIEW OF GLOBALIZATION THESIS : CAPITAL MOBILITY AND THE STATE
Jho, Whasun 연세대학교 동서문제연구원 2003 Global economic review Vol.32 No.4
The purpose of this paper is to analyze the present understanding of the political economy of globalization, in particular the globalization of capital. In the contemporary age, the regulatory capacity of the state seems to stand in a different relation to the transnational capital because its space is not bound by conventional jurisdictions. This paper closely examines how the transnational capital influences the politics of the state. It takes the increasing capital mobility as one of the key features of globalization, and explores the impact of capital mobility on politics in relation to the convergence and divergence debates among scholars. It deals in detail with the impacts of globalization on monetary autonomy of the state, on financial market governance, and on labor market governance, and discusses how capital mobility influences the politics of the state, enforcing the power configuration among the state, capital, and labor.

Desorption of lead (Pb) and cadmium (Cd) from contaminated sediments was investigated to clarify the effect of stabilizing agents on Cd and Pb desorption kinetics. The desorbed aqueous Cd and Pb concentrations and the residual amounts of Cd on the sediments in the desorption tests were best fitted to a pseudo-second-order kinetics with the highest R<SUP>2</SUP> values among the models used in the kinetic studies. The average residual Cd on sediments were 24% and 19% less in the presence of apatite and birnessite, respectively, than in the absence of them. However, the Pb desorption was not affected by the stabilizing agents. The negligible aqueous concentrations of desorbed Cd and Pb in the presence of apatite and birnessite suggest the stabilization of desorbed Cd that was facilitated by apatite and birnessite and Pb. The kinetics study with Cd shows that the rate constants are not affected, but the desorption extents are affected in the presence of apatite and birnessite. The Tessier sequential extraction method and toxicity characteristic leaching procedure indicate that Pb is more strongly bound on the stabilizing agents than Cd. Overall, birnessite and apatite can be successfully applied in remediation of Cd and Pb contaminated sediment.
Aerobic bacteria from oral cavities and cloaca of snakes in a petting zoo

It is important to identify the bacteria in snakes because they can cause disease; importantly, bacteria such as Stenotrophomonas maltophilia, Escherichia coli, Proteus vulgaris etc. could be pathogens especially in hospitalized, debilitated hosts, and immunocompromised patients. To analyze the distribution of snakes' bacteria in petting zoo, samples from 20 snakes were collected from 2002 to 2008. Nine bacteria species were isolated from both oral and cloaca while four and six species were identified only from oral and cloaca, respectively. Except for Actinobacter sp., all of the identified strains are opportunistic pathogens, and most of them can cause nosocomial infections in humans. Present results indicate that prevalence of various zoonotic bacterial strains in snakes could be involved in potential transfer of these bacteria into caretakers and other animals. Therefore, it needs to examine the antibiotic resistance of these pathogens to prevent outbreaks.
