박범철 문화영토연구원 2022 문화영토연구 Vol.3 No.1

The purpose of this study was to examine multicultural education programs based on the local community from 2018 to May 2022. It was confirmed that the change in perception gained by migrant participants, villagers, and teenagers who settled in Dongjak-gu together during the village tour led to the promotion of multicultural sensitivity. After examining the problems of existing multicultural education, the direction of multicultural education in schools was proposed in connection with community understanding education, Korean language culture education, and global citizenship education. It was to grasp the attitude of having global citizenship and empathizing and respecting each other with the heterogeneous social identity of natives and migrants, teenagers and women who are subject to multicultural education. As a suggestion, participants of Dongjak Dada Group proposed how to meet the villagers and make social voices with the global municipal democracy system called the Youth Project with Flowers through village activities in 2022. This study has limitations in that the lack of significant linkage activities due to the COVID-19 pandemic and the methodology derived through strict verification could not be applied. It is questionable whether the analysis and interpretation of the results are appropriate given that the "Project with Flowers," which introduced many social implications, is also an ongoing program in 2022. Nevertheless, it is meaningful in that migrants, native residents, and adolescents can try a new type of multicultural education as a member of a village association community beyond the existing school or institution-centered multicultural education category. 본 연구는 2018년부터 2022년 5월까지 지역사회를 기반으로 이뤄지고 있는 다문화교육 프로그램을 고찰하는 것을 목적으로 삼았다. 동작구에 정착한 이주민 참여자와 마을 주민, 그리고 동작구에 있는 고등학교를 다니는 청소년들이 지속적으로 마을 탐방을 진행하면서 얻게 된 인식의 변화가 다문화 감수성 증진으로 이어지고 있음을 확인할 수 있었다. 기존 다문화 교육이 가지고 있는 문제점을 고찰한 후, 학교 다문화교육 방향을 지역사회 이해교육, 한국어 문화교육, 세계시민교육과 연결지어 제안해보았다. 다문화교육 대상인 선주민과 이주민, 청소년과 여성이라는 이질적인 사회적 정체성을 가지고 어떻게 세계시민성을 갖고 서로에게 공감하고 존중하는지 태도를 파악하는 것이었다. 제언으로는 동작다다름단 참여자들이 2022년 마을활동을 통해 <꽃을 든 청소년 프로젝트>라는 세계시민주제를 가지고 어떻게 마을 주민들을 만나 사회적 목소리를 내는가에 대하여 제안하였다. 본 연구는 코로나 19 팬데믹으로 유의미한 연계 활동의 부족 및 엄격한 검증을 통해 도출된 방법론을 적용하지는 못하였다는 한계점을 지니고 있다. 많은 사회적 의미를 함의하고 있다고 소개한 <꽃을 든 프로젝트> 또한 2022년 현재 진행 중인 프로그램이라는 점에서 결과 분석과 해석이 과연 적절한지 의문스럽다. 그럼에도 기존의 학교나 기관 중심 다문화교육의 범주를 벗어나 마을결합공동체의 일원으로 이주민과 선주민, 그리고 청소년이 새로운 형태의 다문화교육을 시도하여 궁극적으로 다문화감수성을 증진할 수 있는 방법론에 대한 새로운 관점을 제시할 수 있다는 점에서 그 의의를 찾을 수 있다.

Synthesis, Microstructure, and Physical Properties of Metallic Barcode Nanowires

박범철,김영근 대한금속·재료학회 2017 METALS AND MATERIALS International Vol.23 No.3

With rapid progress in nanotechnology, nanostructured materials have come closer to our life. Single-componentnanowires are actively investigated because of their novel properties, attributed to their nanoscaledimensions and adjustable aspect ratio, but their technical limitations cannot be resolved easily. Heterostructurednanomaterials gained attention as alternatives because they can improve the existing single-componentstructure or add new functions to it. Among them, barcode nanowires (BNWs), comprising at leasttwo different functional segments, can perform multiple functions for use in biomedical sensors, informationencoding and security, and catalysts. BNW applications require reliable response to the external field. Hence,researchers have been attempting to improve the reliability of synthesis and regulate the properties precisely. This article highlights the recent progress and prospects for the synthesis, properties, and applications of metallicBNWs with focus on the dependence of the magnetic, optical, and mechanical properties on material, composition,shape, and microstructure.

박범철,김석영,정수진,Park, Bum Chul,Kim, Seok Young,Jung, Su Jin 대한소아소화기영양학회 2005 Pediatric gastroenterology, hepatology & nutrition Vol.8 No.2

목 적: 장중첩증으로 진단받았던 환아들을 연령군으로 나누어 임상증상 및 치료 결과를 비교하여 향후 장중첩증의 진단과 치료에 도움을 주고 연구를 시행하였다. 방 법: 2000년자 1월부터 2004년 5월까지 포천중문의대 분당차병원 소아과 및 외과학교실에서 장중첩증으로 진단된 159명 환아를 대상으로 연령군에 따라 후향적으로 연구하였다. 5개월 미만 군을 I군, 5~11개월 군을 II군, 12개월 이상 군을 III군으로 정하였으며, 연령, 성별 및 계절적 분포, 원인, 임상 증상, 방사선소견, 장중첩증의 유형, 수술방법, 재발률에 대하여 비교분석하였다. 결 과: 주요 임상증상 및 징후를 세 군에서 비교하였을 때 주기적인 보챔 증상은 세 군 모두에서 가장 흔한 증상이었다. 보챔 증상과 동반된 구토는 I군에서 통계적으로 유의하게 높았으나(p<0.05), 혈변의 경우 나이가 많은 III군에서 더 높은 빈도를 나타냈다(I군: 66.7%, II군: 75.4%, III군: 77.9%). 증상 발현 후 장중첩증으로 진단될 때까지 걸린 경과시간은 각 군에서 평균 21시간, 20시간, 22시간으로 세 군 사이에 별다른 차이가 없었으나 증상 발현 후 48시간 이후에 진단된 환아는 어린 연령인 I군에서 통계적으로 유의하게 많았다(I군: 23.8%, II군: 4.9%, III군: 7.8%). 단순 복부 방사선 촬영상 I군에서 장폐쇄소견이 타군에 비해 유의한 차이를 보였다(p<0.05). 치료는 일차적으로 바륨 정복술을 시도하였으며 실패율은 I군 52.4%, II군 26.2%, III군 14.3%로 I군에서 유의하게 높았다. 결 론: 나이가 어린 군에서 증상이 뚜렷하지 않아 진단이 늦어지고 그로 인해 수술적 치료 결과가 많았다. 따라서 나이가 어린 영아에서는 보챔과 동반되는 구토 증상이 있을 때 장폐쇄에 대한 보다 적극적인 검사 및 세심한 관찰로 진단이 지연되지 않도록 장중첩증을 항상 감별하는 것이 필요할 것으로 생각된다. Purpose: We divided the children diagnosed with intususception into three different age groups and compared the clinical symptoms and treatment outcomes in order to analysis diagnosis and treatment of Intusussception. Methods: A retrospective chart review was established of 159 patients diagnosed with intussuception who had been admitted to Department of Pediatrics and General Surgery, Bundang CHA hospital from January, 2000 to May, 2004. We divided the patients into three groups, according to their age. Those who were under five months of age (group I; 21 patients), those between 5~11 months of age (group II; 61 patients), and those older than 11 months of age (group III; 77 patients). Then we compared the age, sex, seasonal distribution of occurrence, the cause, the clinical features, radiologic review, the type of intusussception, surgical methods, recurrence rate and treatment outcomes, among these three groups. Results: On comparing the clinical symptoms and signs among the three groups, the most common major clinical symptom and sign was irritabiltity in all three groups. Vomiting with irritability was statistically more common in group I (p<0.05) and bloody stool was most frequent in group III. The average time taken until a diagnosis was made after the symptom onset was, 21 hours in group I, 20 hours in group II and 22 hours in group III. Which showed no significant difference. But there was a higher rate of delayed diagnosis in group I, which took over 48 hours until the diagnosis was made (group I; 23.8%, group II; 4.9%, group III; 7.8%). Simple abdominal X-rays showed more frequent instances of intestinal obstruction in group I (p<0.05). The primary treatment done was barium enema which showed a failure rate of 52.4% in group I, 26.2% in group II and 14.3% in group III. Showing the highest failure rate in group I. Conclusion: The youngest group had vague symptoms which lead to delayed diagnosis and more frequent surgical procedures. As so, we advocate the importance of further evaluation and close observation, considering intussusception in children with symptoms of irritability and vomiting, especially in the early infant group.

In this paper, the experimental study and finite elements analysis were conducted on homogeneous and dissimilar metals single lap-shear bonded joints to investigate the factor that affect the joint failure load. It was found that factors which have the significant effects on the failure load of the joint was stiffness of the adherends. And from experimental results, it can be confirmed that the failure load increases linearly with overlap length increases. And the failure load of dissimilar metal joints is approximately 1KN(10 ~17%) larger than homogeneous metal joints. In order to confirm this phenomenon, the stress distribution and strain distribution of the specimens were analyzed through the finite element analysis. The difference between homogeneous metals joints and dissimilar metals joints is that stress and strain in adhesive are concentrated at the end of the overlap zone close to aluminium which has lower rigidity than aluminium in case of dissimilar metals joints. From high rigidity of steel, the stress concentration in bonds are decreased and it cause increase of the failure strength at dissimilar metal joints.

Recently, many international arbitration institutions have responded to the business requirements of their users and have revised their rules to enhance the time and cost efficiency. Korean Commercial Arbitration Board (KCAB) revised the international arbitration rule in 2011, introducing new arbitration mechanisms like the expedited procedure. Also other Asian arbitration institutions introduced the expedited procedure in their international arbitration rules. Now expedited procedures are regarded as a very attractive system in the field of international arbitration. Accordingly, this paper reviewed the expedited procedures of four Asian countries, including China(CIETAC), Hong Kong (HKIAC), Singapore(SIAC) and Korea(KCAB). The purpose of this study is to find out meaningful implications to improve the Korean system. Based on this review, some recommendations are suggested as follows. First, the scope of the expedited procedure has to be adjusted upward than the current 200 million won. Second, there should be a fee schedule only for the expedited procedure. Third, in case of small amount international disputes, written examination should be more used in the expedited procedure. Finally, KCAB should make strong efforts to improve the awareness and usage of the expedited procedure in Korea.
