목 적 : Kikuchi 병은 고열을 동반한 양성 림프절 비대를 특징으로 하는 아급성 괴사성 림프절염이다. 주로 젊은 여성에게 발생하며 소아에 있어 드물게 보고되고 있다. 병인으로는 바이러스와 연관성, 자가 면역기전 등이 제시되고 있으나 정확히 밝혀지지 않은 상태이다. 최근 저자들은 소아에서 발생한 괴사성 림프절염 5례를 경험하였기에 소아에 있어 Kikuchi 병의 임상적 고찰을 하였다. 방 법 : 2001년 1월부터 2006년 6월까지 경희대학교 소아과에 Kikuchi 병으로 진단 받은 환아 5명을 의무기록을 통해 발생 연령, 성별비, 계절별 발생빈도, 임상증상, 과거력, 검사 소견, 림프절의 발생 부위 및 크기, 방사선학적 소견 등을 조사하였다. 결 과 : 남아가 2명, 여아가 3명이었으며, 평균 연령은 9년 9개월(8년 2개월-12년 6개월)이었다. 주된 증상은 지속되는 발열과 림프선 비대로 병원을 방문하였다. 모든 환자는 항생제 치료를 받았으며, 2명의 환자에게서 발진이 발생하였다. 1례에서 초음파 검사상 Kikuchi 병이 의심되는 괴사성 변화가 관찰되었다. 3례에서 추가적으로 컴퓨터 단층촬영을 실시하였다. 입원 후 절제 생검할 때까지 소요된 시간은 10.2일(7-15일)이었다. 5례 모두 림프절 절제 생검 후 조직 검사상 괴사성 림프절염으로 확진하였다. 결 론 : Kikuchi 병은 진단 전에 불필요한 검사와 항생제 치료를 하며 이로 인해 입원 기간도 길어진다. 이에 저자들은 소아에 있어 Kikuchi 병의 임상 양상을 고찰하였다. Purpose : Kikuchi disease is a subacute necrotizing lymphadenitis characterized by fever, cervical lymphadenopathy and benign self-limiting course in young women especially, but rare in children. Their etiopathology is still unknown, but involved viruses and autoimmune mechanism were proposed. We investigated the clinical and laboratory characteristics of Kikuchi disease in children. Methods : Five patients were diagnosed of Kikuchi disease from January 2001 to June 2006 in Kyunghee University Hospital. We reviewed their medical records retrospectively and analyzed clinical and laboratory findings. Results : The mean age of 5 patients (male to female ratio; 2:3) was 9 yr 9 mon(range: 8 yr 2 mon-12 yr 6 mon). The chief complaints were sustained fever and cervical lymph node that was unilateral, tender and swollen. All patients were treated with antibiotics before diagnosis was made, and rash developed in 2 patients. One patient showed necrotic change in ultrasound with which we suspected Kikuchi disease. Three patients were examined by CT scan additionally. The interval between admission and cervical lymph node excisional biopsy ranged from 6 days to 15 days, and mean period was 9.6 days. All pathological findings were compatible to necrotizing lymphandenitis. Conclusion : Unnecessary laboratory and imaging studies, and treatment with antibiotics tend to be done before making diagnosis, and that caused prolonged hospitalization. Therefore we studied the clinical and laboratory characteristics of Kikuchi disease in children.

본 연구의 목적은 학습 빅데이터 분석을 통해 추천 알고리즘을 스스로 고도화하는 머신러닝 추천모듈이 적용된 개인 맞춤형 학습 플랫폼이 학생들의 학습시간, 자기주도적 학습능력, 수학에 대한 태도, 수학학업성취도에 미치는 영향과 이들 사이의 구조적 관계를 검증하는 것이다. 연구 결과 개인 맞춤형 학습은 학생들의 학습시간, 자기주도적 학습능력, 수학에 대한 태도, 수학학업성취도에 대해 긍정적인 영향을 미치고 있었다. 또한, 맞춤형 학습과 수학에 대한 태도와 수학학업성취도의 관계에서 학습시간과 자기주도적 학습능력의 매개효과가 유의하였다. The purpose of this study is to verify the effects of personalized learning platforms applied with machine learning recommendation modules that upgrade recommended algorithms by themselves through learning big data analysis on students' learning time, self-directed learning ability, mathematics achievement, and attitudes toward mathematics, and the correlation between them. According to the study, customized learning affected learning time, self-directed learning ability and mathematics attitude, while learning time affected self-directed learning ability. Self-directed learning ability has had a significant impact on the attitude of mathematics and mathematical achievements. As a result of the mediated effectiveness test, the indirect impact of customized learning on mathematics attitude and mathematics performance was significant through the medium of learning time and self-directed learning ability.

The recent rise in the unstructured data generated by social media has resulted in an increasing need to collect, store, search, analyze, and visualize it. These data cannot be managed effectively by using traditional data analysis methodologies because of their vast volume and unstructured nature. Therefore, many attempts are being made to analyze these unstructured data (e.g., text files and log files) by using commercial and noncommercial analytical tools. Especially, the attempt to discover meaningful knowledge by using text mining is being made in business and other areas such as politics, economics, and cultural studies. For instance, several studies have examined pending national issues by analyzing large volumes of texts on various social issues. However, it is difficult to create satisfactory information services that can identify R&D documents on specific national issues from among the various R&D resources. In other words, although users specify some words related to pending national issues as search keywords, they usually fail to retrieve the R&D information they are looking for. This is usually because of the discrepancy between the terms defining pending national issues and the corresponding terms used in R&D documents. We need a mediating logic to overcome this discrep‘ancy so that we can identify and package appropriate R&D information on specific pending national issues. In this paper, we use association analysis and social network analysis to devise a mediator for bridging the gap between the keywords defining pending national issues and those used in R&D documents. Further, we propose a methodology for packaging R&D information services for pending national issues by using the devised mediator. Finally, in order to evaluate the practical applicability of the proposed methodology, we apply it to the NTIS(National Science & Technology Information Service) system, and summarize the results in the case study section.

明治憲法下における立憲主義の考察 : Under Meiji constitution law

李圭夏 啓明大學校 國際學硏究所 日本硏究室 1986 日本學誌 Vol.5 No.-

The first modern constitution law adopted in Japan in 1889, coming after strong SAMURAI centrol government dominated by feudal system for nearly two hundred half centries. In this constitution, it was aimed that restoration of real power for soverignity of Meiji Emperor based especially on the monarchy focusing constitution in Germany and Austria in 19th centry for the purpose of improving national power in international society taking both of advanced industrial and legal system after Western civilization. Therefore, both of jurist and people criticized Meiji constitution as pseudo constitutionalism(Scheinkonstitutionalismus), in which strong imperial sovereignity and authoritarian administration established. In the meantime, a line of legal theory backed by many scholars who beleived in modern constitutionalism oriented from western country were rised against imperial monarchy and arbitrary government, emphasizing democracy that all sovereignity of political power come from people, and constitutionalism that government limited by the terms of constitution, not government limited only by the desire and capacities of those who exercise practical powers, even though Emperor Meiji. They particularly criticized that Emperor's power was as unilmited as 17th centrie's legal doctrine of Devine Right of Crowen in England neglecting fundamental right of human and limitating rights of legislation by parliament. However, the suggestions of constitutionalism instead of imperial monarchy was rejected by Meiji government and scholars were cruelly impeached by militarist government during the World War Ⅱ later on. In 1947, Constitution of Japan was revised by American enfluence under the occupation, to democratic constitutionalism obtained, such as provisions: division of power system, and protection of human right etc.
