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.
Symmetric searchable encryption with efficient range query using multi-layered linked chains
Jho, N. S.,Chang, K. Y.,Hong, D.,Seo, C. Kluwer Academic Publishers 2016 The Journal of supercomputing Vol.72 No.11
<P>Searchable encryption is an encryption system which provides confidentiality of stored documents and usability of document search at the same time. Remote cloud storage is the most typical application for searchable encryption. By applying searchable encryption, inside attacks can be prevented fundamentally. Designing searchable encryption which supports various queries-for example, range query, conjunctive keyword query, etc.-is also important for convenience. In this paper, we focus on range query problem. Up to now, only a few results have been proposed, in which the main functions are constructed using public key cryptosystems. Therefore, the amount of computations for encryption and search is large. Furthermore, search time depends on the size of the entire database. We propose a new searchable encryption protocol which is based on a symmetric key encryption and linked chain structure instead of public key-based techniques. The main contribution of the protocol is reducing the computation cost for search remarkably. In reality, the amount of computations depends on the number of documents that are matched to a query instead of the size of the entire database.</P>

<P><B>Abstract</B></P><P>Bereaved family members of cancer patient are at risk of having psychological problems such as anxiety and depression. However, prevalence and associated factors of anxiety and depressive symptoms among this population have not been explored in Korea.</P><P>We conducted a nation-wide cross-sectional questionnaire survey of 3522 bereaved family members of cancer patients who died at 44 hospice palliative care unit (HPCU) in Korea in 2012. The questionnaire comprised the Hospital Anxiety and Depression Scale (HADS) and Good Death Inventory (GDI). Deceased patient's age, sex, primary site of cancer, duration of stay at HPCU, awareness of terminal status, bereaved family member's age, sex, and relation to the deceased were collected from Korean Terminal Cancer Patients Information System.</P><P>1121 returned questionnaires were analyzed (response rate, 31.8%). Using a cut-off value of 8 for HADS subscale, the prevalence of anxiety and depressive symptoms was 48.0% and 57.6%, respectively. Mean scores for HADS-A and HADS-D were 7.88 ± 4.87 and 8.91 ± 4.82, respectively. Among the bereaved, older age, being a spouse to the deceased, family members of younger patient, and negative score for a few GDI items were significantly associated with an increased risk of having anxiety or depressive symptoms in the multivariate logistic analysis.</P><P>In conclusion, we noted the high prevalence of anxiety and depressive symptoms among the bereaved of cancer patients and identified associated factors for these psychological morbidities. Systematic efforts are needed to improve the mental health of the bereaved family members of cancer patients.</P>

<P><B>Abstract</B></P><P><B>BACKGROUND</B></P><P><B>Military areas such as firing ranges have serious contamination problems due to both heavy metals and nitroaromatic compounds (NACs). The feasibility of modified Fenton reactions for remediation of NACs is studied by investigating the fate of lead (Pb) and copper (Cu) during the modified Fenton reactions and its effect on the degradation of 2,4‐dinitrotoluene (2,4‐DNT) in soils at various hydrogen peroxide (H<SUB>2</SUB>O<SUB>2</SUB>) concentrations.</B></P><P><B>RESULTS</B></P><P><B>During the reactions, the Pb fate was not affected at ≤0.2 mol L<SUP>−1</SUP> H<SUB>2</SUB>O<SUB>2</SUB>, but final aqueous phase Pb was higher in the samples than in the controls at >0.2 mol L<SUP>−1</SUP> H<SUB>2</SUB>O<SUB>2</SUB>. These changes in the Pb fate resulted in interference with 2,4‐DNT degradation at ≥0.2 mol L<SUP>−1</SUP> H<SUB>2</SUB>O<SUB>2</SUB>. Similarly, aqueous phase Cu was higher in samples with >0.2 mol L<SUP>−1</SUP> H<SUB>2</SUB>O<SUB>2</SUB> than in the controls; however, unlike Pb, these changes did not have adverse effects on 2,4‐DNT degradation.</B></P><P><B>CONCLUSION</B></P><P><B>The different effects of heavy metals such as Pb and Cu on 2,4‐DNT degradation in soils during modified Fenton reactions need to be understood to optimize 2,4‐DNT degradation performance. The results help to advance the Fenton reaction applications for the remediation of soils contaminated with Pb or Cu and 2,4‐DNT mixtures. © 2012 Society of Chemical Industry</B></P>
