The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.

A number of structural and modal parameters are derived from the strong motion records of an instrumented G + 9 storeyed RC building during Bhuj earthquake, 26 Jan. 2001 in India. Some of the extracted parameters are peak floor accelerations, storey drift and modal characteristics. Modal parameters of the building are also compared with the values obtained from ambient vibration survey of the instrumented building after the occurrence of earthquake. These parameters are further used for calibrating the accuracy of fixed-base Finite Element (FE) models considering structural and non-structural elements. Some conclusions are drawn based on theoretical and experimental results obtained from strong motion records and time history analysis of FE models. An important outcome of the study is that strong motion peak acceleration profile in two horizontal directions is close to FE model in which masonry infill walls are modeled.

The purpose of this research is to survey minpo(the nations pojagi), especially supo(the embroidered pojagi), of the Yi Chosun of Korea during the nineteenth century. This study explores the history and background of minpo, its characteristics, including forms, designs, materials, and how they related to women's daily life during the Yi Chosun in social and cultural aspects. There were minpos for use in everyday life as well as for special occasions such as weddings, funerals and religions rites, including Buddhist and other services. The research undertaken here is done by classifying minpos according to composition, design, pattern and motif.

Natural history museums preserve and manage the creatures living in each country, so they play unique roles for bio-diversity, and in fact, their roles are really instrumental for the collection, preservation, research, exhibition and education of creatures in the 21st century. Therefore, this research has the purpose to survey the status of our country's existing natural history museums, analyze their visual perception space structural characteristics, and ultimately utilize their characteristics as basic data in planning out and designing spaces of natural history museums to be established later on. As for the research scope, the research selected as research subjects 7 natural history museums that currently have composite set of open type and mixed type and have been accommodating comparatively active exhibitions since 2000 among 10 or so natural history museums in our country. Research method is that the research analyzed the exhibition spaces of 7 natural history museums by using depthmap program which can analyze space with visual graph analysis function, and analyzed the visibility among unit areas by each natural history museum integration and exhibition contents composition. In such analysis method, the research was able to quantitatively analyze the visual characteristics of exhibition space that induces and adjusts the motion of audience. Visual perception quantitative analysis as in this research will enhance exhibition design by considering the correlation between audience and exhibited items when planning out natural history museums space to be established later on.

본 연구는 전근대 우리 땅을 밟은 외국인들인 벨테브레와 하멜을 역사 수업에 어떻게 활용할 수 있는지에 대한 연구이다. 벨테브레와 하멜은 모두 네덜란드 사람이며, 조선에 먼저 표착한 이는 벨테브레였다. 네덜란드 동인도회사 소속의 선원이었던 벨테브레는 1627년 제주도에 상륙하였고, 이후 귀국하지 않고 '박연'이라는 이름으로 조선에 귀화하여 조선에 귀화한 최초의 서양인이 되었다. 박연은 당시 북벌정책을 실시하고 있던 조선에서 훈련도감에 근무하며 조선의 병기개발 및 개량에 커다란 역할을 다하였다. 네덜란드 동인도회사의 무역선 포수였던 하멜은 1653년 조선에 표류하여 13년 동안 여러 계층의 사람들과 접촉했고, 여러 지역으로 끌려 다니면서 당시 조선의 풍물과 풍속에 대한 사정을 자세히 관찰할 수 있었다. 교류사 학습은 세계사의 종합적인 이해에도 도움을 준다. 학생들은 서양사와 동아시아사, 한국사를 구분해서 배우기 때문에 세계 역사의 종합적인 흐름이나 시대별 서양과 동양의 모습에 대한 종합적인 이해가 힘들 수 있다. 전근대의 동서교류와 관련된 인물들에 대해 학습하는 것은 학생들로 하여금 서양과 동양의 역사를 세계 역사의 흐름 안에서 같이 연결 지어 이해할 수 있도록 해줄 것이다.

Objectives: This study aimed to identify the key components and tools for Comprehensive Dental Hygiene Care (CDHC) among dental hygienists and provide foundational data for widespread implementation in dental institutions. Methods: A third Delphi survey involving experts derived the CDHC components and materials. Dental hygienists' characteristics and the CDHC application status were analyzed for frequency. The perceived need for and willingness to apply the CDHC components based on general characteristics were assessed using t-tests. Results: The results of the Delphi survey identified the following CDHC components: 11 for medical history; three, dental history; five, oral hygiene practices; seven, dental conditions; three, occlusion conditions; six, periodontal conditions; and, three, other examinations. Planning included 3 items for healthy gums and 4 for gingivitis and mild periodontitis. Evaluation included 7 items for mild periodontitis, 5 for patient education, and totally 27 CDHC-related materials. Dental hygienists' needs and willingness varied, with higher levels among those in clinics, university graduates, those in counseling or managerial roles, team leaders or those at higher positions, and those with >6 years of experience (p<0.05). Conclusions: The Delphi survey identified the CDHC clinical application process, confirming the strong desire of dental hygienists to apply it in practice.
