This study aims to examine the effects on citizenship through the experience participating community in social studies classes and to study their process. In this vein, I examine firstly whether there are differences of citizenship between community participation classes as experimental groups and lecture classes as control groups. Secondly, I examine the effects of the deliberation in the participants` citizenship. The result of this study are follows. First, community participation classes have more positive increasing effect of citizenship than lecture classes. In details, the community participation in classes leads the students to acquire the sub elements of sense of community, such as membership, influence, integration and fulfillment of needs and emotional connection more than the students that have took teacher-led lessons. And it also allows them to increase more the sub elements of political attitude, such as political confidence, political efficacy, political tolerance and participation consciousness. And the frequency of deliberation that students have experienced in participation affects the increasing of students` citizenship. However, this study shows that individual factors and subject-related factors do not affect their citizenship. This results indicate a few implications. Firstly, related to the effects of increasing citizenship of community participation classes, lots of studies on this classes as a type of class should be studied. Secondly, the process of deliberation in the participation should be studied more detail.

The purpose of this study is to design and implement project based learning(PBL) in order to improve global citizenship and to verify its effects. I reconstructed the 2015 revised middle school social studies curriculum to design a PBL to 'Become a Global Citizen'(BGC) and conducted it to M middle school students. The results showed that the theme of the curriculum was to reconstruct the 'BGC' PBL, which extracted 3 categories of ⅰ) cultural diversity & localization/globalization, ⅱ) environmental problem & sustainable environment and ⅲ) global society & the problems in modern society. After conducting practical activities, it was found that the PBL was effective in improve students' global citizenship. Additionally, the achievement of evaluating participation and practice was affected. For global citizenship education, it is necessary to reconstruct the curriculum. Also practical and behavioral area, not just cognitive and emotional areas should be considered. To do this, teaching-learning strategies such as PBL accompanied by participation and practice is needed.

한국 유학생들의‘인종차별경험’이해에 관한 질적 사례 연구

김현경(Hyoun-gyoung Kim) 한국사회과교육연구학회 2011 사회과교육 Vol.50 No.1

본 연구의 목적은 영국에서 유학중인 한국 유학생들이 인종적 소수집단으로서 차별받은 경험을 어떻게 인식하고 있는지 알아보고자 하는 것이다. 유럽을 비롯한 서구사회에서 은밀하고 모호한 형태의 인종차별이 확산되면서, ‘인종차별의 일반지식’이 부족한 소수집단 성원들이 이러한 형태의 암시적 인종차별을 알아채는 것은 쉬운 일이 아니다. 영국의 한 대학교에서 공부하는 24명의 한국 유학생들의 인종차별 경험을 인터뷰한 결과, 이들은 다른 소수집단과 마찬가지로‘차별 부인’및‘차별최소화경향’을 보이고 있었다. 구체적으로는 그들이 받은 차별을‘부족한 영어’에 귀인하고, 가해자를‘교육받지 못한 어린아이들’로 동정하며, ‘친절한 이방인의 태도’를 보이며, 마지막으로‘가해자로서의 자기성찰’의 태도로 한국에서의 인종차별을 역으로 비판하는 자세를 보였다. 궁극적으로 소수집단 구성원으로서의 경험이, 피해자 중심의 입장을 공감하고 타 문화를 이해하고 존중할 수 있는 계기가 될 수 있음을 알 수 있었고, 이러한 경험이 다문화적 시민성과 연결될 수 있는 가능성을 찾는 연구가 더욱 요구된다. This study aims to analyze minority group’s racial encounters on 24 Korean students studying in a UK university. In recent decades, on account of ambiguous and covert forms, it is difficult that people of minority groups know their racial discriminations. In this study, qualitative method and semi-structured interview was used and the data was recruited by Korean Society. Followings results from this study. First, because they would protect their self-esteem, Korean students tend to deny or minimize their racial discrimination in four ways: they attributed discriminations to their poor English, they did not blame those who discriminated them because they are non-educated children, they showed ‘good-guest attitude’, and as a reflection of discriminator they blame Korean people who discriminated other minorities in Korea. Second, some of them assessed their racial encounters as racism. They hesitated to say what they experienced because their experiences could be very covert or ambiguous. Even some of them seemed to feel their racial discriminations only in public institutions: they probably did not perceive personal discriminations as racism. This study shows that how minority group’s people perceive their racial discriminations and how they deny or minimize their racial encounters. It also shows how ethnic and racial major people can improve their multicultural citizenship which Korean people can see ethnic others with empathy and tolerance in Korea changing rapidly into a multi-racial and multi-ethnic society.

Posterior reversible encephalopathy syndrome (PRES) has been described in various clinical settings, including severe hypertension, eclampsia, lupus and immunosuppressive therapy. We report a 27 year-old female systemic lupus erythematosus patient who developed severe headache, seizure and hemiparesis during her lupus nephritis flare. Magnetic resonance image (MRI) showed multi-focal high signal intensity lesions in the parieto-occipital cortex bilaterally and in the subcortical white matter. Her condition improved with immunosuppressive treatments, antihypertensives and hemodialysis. The extent of her lesions decreased on follow-up MRI 2 months later. This case suggests that PRES can be treated with immunosuppressive drugs that do not increase blood pressure.

본 논문에서는 동적 공역 형상 관리상의 변경이 발생할 때에 대한 항공 교통 효율성 평가에 사용될 궤적기반 항공 교통량 분석 소프트웨어의 설계 결과를 기술한다. 본 소프트웨어는 비행계획서에 기초한 인천 FIR의 항공 교통에 대한 통계 자료를 산출하고, 비행계획서 상의 항공기 종류, 순항고도, 속도, 이동 경로 등으로부터 도출된 궤적 모델링 자료를 이용하여 항공로 이용율, 관제사 관제량을 분석하도록 설계되었다. 공역 설계 및 항공로 입력 정보와 함께 장기간에 걸친 궤적 모델링 자료를 한꺼번에 입력받아 일괄 처리하는 방식을 적용함에 따라, 본 소프트웨어는 공역 및 항공로 등의 수정 내용에 따른 교통량 변화를 빠르게 예측할 수 있는 장점을 가진다. In this paper, the design result of the trajectory-based air traffic analysis software which is going to be used to assess air-traffic efficiency in case that some modification"s made in dynamic airspace configuration, is described. The software has been developed to make statistical data about air-traffic in Incheon FIR based on the RPL, and to analyze the airway utilization and controller workload using the trajectory modeling data which are derived from the aircraft type, cruise speed, cruise altitude, and routes and fixes in the RPL. Since it batch-processes the long-term trajectory data with other inputs such as airspace, route information and so on, it has the advantage of quickly predicting the traffic variation when some change in airspace and route information is made.

This study purports to investigate a potential effect of pro-human rights culture in schools on civil consciousness of youths. The independent variables include those variables such as the level of pro-human right culture in school, current status of human rights in schools, experience on discrimination and youths`` participation upon school affairs. The model controls demographic characteristics of youths(gender, age, a dummy for multi-cultural families), psychological attributes(self-respect, belief upon self development, self-concept), school-related variables(academic achievement, a dummy for innovation schools), and nurturing attitudes of parents. The multiple regression analysis shows some meaningful findings. First and foremost, the level of schools`` pro-human rights culture turns out to have a significant impact upon youth``s levels of civil consciousness. Secondly, some control variables significantly affect youths`` level of civil consciousness. Those are gender, school satisfaction, self-concept, self-respect and so on. Lastly, it is not the innovation school per se, but the actual programs in schools for pro-human rights that matters for youths``s civil consciousness. This study hopes to contribute to expand the recognition that pro-human rights culture in school positively works for youths`` development of civil mind. This study also acknowledges that future research are to focus on finding the potential paths on how those cultures in schools affect youths`` civil attitudes.
