In this study, author examined the effect of the concentration of the inorganic polyphosphate on the process of the bone regeneration by using the 6 weeks old rabbit with the weight of 2.0kg in average. we performed the experiment by using TR-eITFE membrane filled with collagen immersed with 1%, 2%, and 4% of inorganic polyphosphate, respectively, after removing the proper sized cort-ical bones from the calvaria of rabbit. The experimental results were compared with the one of the following four groups: The control group for membrane only, experimental group I for membrane filled with collagen im-mersed with 1% of inorganic polyphosphate, experimental group II for membrane filled with collagen immerse with 2% of inorganic polyphosphate, experimental group III for membrane filled with colla-gen immersed with 4% of inorganic polyphosphate. The fragments of the tissue with membrane were obtained from each group of the sacrificed rab-bits for 4 or 8 weeks sustained after surgery, were then prestained and coated. New bone formation was assessed by histomorphometric and statistical analysis. We may draw the conclusions from these experiments as following: 1. Collagen was an excellent carrier with a minimal inflammatory reaction and sustaining the form. 2. The sample of the 8th week group has shown the best bone regeneration compared with the cases of all groups including the control group. 3. The samples of collagen immersed with 2% and 4% of inorganic polyphosphate have shown more bone regeneration relative to the sample of the 1% inorganic polyphosphate. 4. The new bone regeneration was shown actively in the group for membrane filled with collagen immersed with 4% of inorganic polyphosphate. With above results, it is strongly suggested the use of inorganic polyphosphate with vehicle under TR-eITFE membrane.

The authors present the fine needle aspiration cytology (FNAC) cytologic findings of a case of extranodal marginal zone B cell lymphoma (MZBCL), which featured abundant plasma cells and eosinophilic histiocytes arising in both parotid glands. A 49-year-old female presented with palpable masses in both parotid glands. She had been suffering from systemic lupus erythematosus and rheumatoid arthritis. The lesions were evaluated by FNAC and smears showed a small number of clusters of oncocytic cells with abundant eosinophilic granular cytoplasm and small nuclei, intermixed with small to medium-sized lymphoid cells containing round to lobulated nuclei, which suggested Warthin's tumor. Some of lymphoid cells had a plasmacytoid appearance, and some scattered large cells contained a large amount of eosinophilic cytoplasm. Bilateral superficial parotidectomy was performed and a histopathologic study indicated MZBCL with abundant plasma cells, intermixed with eosinophilic histiocytes. The presence of oncocytic cells and a mixture of lymphoid and plasma cells indicates Warthin's tumor, but the cytologic features of a relatively monotonous small to medium-sized lymphoid infiltrate suggest the possibility of MZBCL in the clinical setting of an FNAC study performed on a patient suffering from a connective tissue disease.
전환기 대한민국 유아교육기관의 당면과제: 안전인가? 인권인가?

본 논문은 2015년 미래유아교육학회 춘계전국학술대회에 발표된 논문을 수정 보완한 것으로서, 연구자는 우리나라가 처해있는 유아교육기관의 당면과제를 유아의 안전에 초점을 맞출 것인지, 아니면 교사의 인권에 초점을 맞추어 당면과제를 풀어나가는 것이 적절한 것인지에 대하여 논의하였다. 특히, 우리 앞에 성큼 다가온 제 4물결 사회로의 진입으로 인하여 우리의 생활방식에 많은 변화가 있을 것으로 예측하였으며 따라서 보육교육인들도 이에 맞추어 적절한 개방, 소통, 그리고 협업의 마인드를 가지고 우리나라 영유아보육과 교육에 힘써야 함을 강조하였다. This study is a revised version of Keynote paper presented at the Association for Future Early Childhood Education, Fall conference in 2015. The researchers tried to discuss the current issues related to the young children``s safety and early childhood teachers`` rights. The researchers added their concern for the Fourth wave movement in Korean society and the changes that might happen in the future due to the new movement. Moreover, the researchers argued that early childhood professionals should need to be more open to the new information and more cooperative, and good communicators to make a positive impact in the field of early childhood education.
19세기 유럽사를 보는 시각 -리처드 에번스의 『힘의 추구』(2016)를 중심으로-
이영석 ( Young-suk Lee ) 대구사학회 2017 대구사학 Vol.127 No.-
이 글은 리처드 에번스(Richard J. Evans)의 19세기 유럽사 서술, 『힘의 추구: 유럽 1815-1919』를 비평적으로 소개하는 데 목적을 둔다. 힘은 이 책을 관통하는 핵심어다. 19세기 역사 무대는 기존 지배세력 외에도 다양한 사회세력들이 등장해 그들 나름의 힘을 얻거나 발휘하려고 했다. 에번스는 정치에서 기술혁신에 이르기까지 다양한 측면에서 힘의 추구를 다룬다. 자본주의를 중심으로 19세기를 재구성하는 거대담론은 처음부터 포기한다. 에번스는 서술형식에서도 새로운 시도를 하고 있다. 각 장의 서두는 한 개인의 生涯史로 시작한다. 그 개인의 삶의 경험은 그 장에서 다루는 핵심적인 주제와 관련된다. 독자는 각 장의 서두에서 읽은 개인의 삶에 대한 인상과 기억의 영향을 받으면서 그 장의 내용을 읽어가게 된다. 에번스는 이러한 형식을 “역사의 인간적 차원”을 강조하려는 시도라고 밝힌다. 에번스는 각 항목들에 대해 주요 국가와 주변국가의 구별을 두지 않고 다양한 국가와 지역의 사례를 혼합함으로써 역사 이해의 지평을 넓혔다. 그러나 이러한 저술의도가 오히려 단편적이고 분산적인 역사서술을 낳았다. 요컨대, 힘이라는 개념은 19세기 유럽사의 다양한 인간 경험과 변화의 측면들을 서로 관련된 구성체계로 만드는 데에는 취약한 개념처럼 보인다. 다른 한편, 서문에서 지구사적 시각을 강조한 것과 달리, 정작 본문에서 지구사적 시각과 분석은 거의 보이지 않는다. 정치, 경제, 사회, 문화의 모든 변화는 유럽 그 자체의 여러 요인과 상호영향을 통해 이루어지는 것으로 서술된다. This article aims to introduce Richard Evans`s recent book on nineteenth-century Europe, The Pursuit of Power: Europe 1815-1914 (2016) critically. `Power` is the most important key-word in this book. On the historical stage of nineteenth-century Europe appeared not only the existing ruling class but various social forces such as capitalists, labourers, peasants, engineers and scientists etc. to gain or exert their own power. From politics to technological innovation, Evans deals with various pursuits of power. From the beginning, he gives up the grand narrative for writing the history of nineteenth-century Europe on the basis of capitalism or bourgeoisie. Instead, he is also making a new attempt at historiographic type and method. Each chapter begins with an individual`s life history. The experiences of the individual`s life are related to the important subjects that the chapter deals with. Readers will read the contents of each chapter under the influence of their impressions of the individual`s experiences. Evans called this type the human dimension of history. Evans expanded the understanding of nineteenth-century Europe by talking about historical experiences of various countries without any distinction between major countries and periphery ones. But it seems to me that this attempt rather resulted in a fragmentation in historical writing. There seems to be a limit to the extent to which the key concept would encompass various aspects of human experiences in the nineteenth century together. On the other, although he emphasizes the perspective of global history, this book lacks contents written from the global perspective. In short, the key concept `power` seems to be limited to covering the various aspects of human experiences in the nineteenth century together. (Gwangju University/leeyoung314@naver.com)
