목적: 법랑기질 유도체(EMD)가 사람 치주인대 줄기세포(hPDLSC)의 조직 형성능에 미치는 영향을 in vitro와 in vivo 분석 모델을 이용해 평가한다. 재료 및 방법: hPDLSC를 배양하여 운반체와 함께 면역 억제된 쥐 등에 이식하였다; (1)대조군: EMD 처치하지 않은 운반체에 심어진 hPDLSC군 ($EMD^-/hPDLSC^+$), (2)실험군: EMD 처치한 운반체에 심어진 hPDLSC군 ($EMD^+/hPDLSC^+$). 각 군당 5마리씩 시행하고 8주 후 희생하였다. 조직학적, 조직계측학적 분석을 통해 형성된 백악질의 면적과 백악세포의 수 그리고 샤피 섬유의 수를 계측하였으며 면역조직화학적 분석을 통해 백악질과 교원질 형성을 평가하였다. 또한 in vitro에서 hPDLSC의 수용성 교원질과 glycosaminoglycan 형성에 대한 EMD의 효과를 분석하였다. 결과: 조직학적 분석에서 교원질성 치주 인대 조직이 실험군에서 현저하게 많이 생성된 것을 관찰할 수 있었다. 형성된 백악질의 면적과 백악세포의 수는 군 간 차이가 없었으나, 새롭게 형성된 샤피 섬유의 수는 실험군에서 대조군보다 유의하게 많았다(p<0.05). 교원질 형성에 대한 면역조직 화학적 분석 결과, 실험군에서 I, III형 교원질과 hydroxyproline의 발현이 높았다. 또한 in vitro에서 hPDLSC에 의한 수용성 교원질과 glycosaminoglycan 형성이 EMD의 농도에 비례하여 증가하였다 (p<0.05). 결론: EMD는 hPDLSC에 의한 샤피 섬유 및 교원질 생성을 증가시키고, 이는 새로운 백악질의 기능적 부착과 치주조직 재생에 중요한 역할을 한다.

교수인사제도는 유연성과 더불어 공정성과 투명성을 높이기 위한 노력이 필요하다. 교수인사제도와 관련된 법령체계를 체계적으로 정비하여 고등교육법으로 일원화해야 하고, 대학교원의 정원에서 전임교원 중 비정년트랙 교원의 비율이 일정 비율을 초과할 수 없도록 하는 방안을 세울 필요가 있다. 또한 다양한 독립적인 심사기구를 설치해야 한다.

최근 교사가 교직의 전문성을 신장 유지시켜 나가기 위해 수강하는 교원연수의 한 방법으로 원격연수를 선호하고 있다. 하지만 이러한 원격교원연수의 양적 확대에도 불구하고, 학습자의 적극적인 참여 없이 교수자의 내용 전달 수준에서의 연수가 지속되고 있다. 이에 본 연구에서는 능동적인 참여를 함으로써 연수효과를 높여야 하는데 연수의 양적 증가에만 머무르고 있어 원격연수의 질적 개선을 위한 연수자 참여형 원격연수 전략을 제안해 보고자 한다. 이를 위해 원격교원연수의 개념과 배경에 대해 좀 더 자세히 살펴보고 원격연수의 실태를 분석하여 원격교원연수 전략에 적합한 전략을 제시해 보고자 한다.

There is a great deal of effort to improve Computational Thinking in education. In this paper, we define the relationship between SW capability and Computational Thinking, and then examine the current status of pre-service teacher's computing thinking. For this purpose, a survey about the attitude toward SW education and computing thinking was administered to prospective teachers who learned Entry software for one semester. The results of the survey showed that the improvement of abstraction, data analysis, and automation among the pre-service teacher's computing thinking is needed. When educating preliminary teachers, we can see that we need an education method that can increase the analysis and design capability beyond the Entry Software development tool.

Much effort went into the TILLS(Teacher's Information Literacy Licensing System) that Education Reform Committee had proposed and Offices of Education operate now. But TILLS is faced with a crisis due to some problem that makes difficulty of working well in process of running. Here we investigate the problem and suggest that is follows. First, we research for the meaning of "Teacher's Information Literacy" for establishing a pertinent estimate standard. Second, we analyse treatises and found some operational problem on that system. Third we suggest a strategy for promotion of that system.

With the introduction of new teacher evaluation system, teacher librarians' evaluation indicators and questions were presented for the first time. The purpose of this study is to review the validity of current indicators and questions and to develop new one, based on it. The result is as follows : Current indicators mainly focus on the management of school library facility and collection, not on teacher librarians' educational activities and have the low validity to evaluate the expertise of teacher librarians. As a result, this study will suggest new evaluation indicators and questions to evaluate their expertise appropriately.

The purposes of this study were to evaluate the effectiveness of teacher training program for specialized school teacher in invention patent field and to explore the program improvement ideas. The study was carried out through on survey method and using program evaluating model developed for this study. The study subjects are 39 specialized high school teacher participated in training program about invention patent field at CNU-IECT(Invention education center for teacher). The data collection was done on August 2, 2014. The 37 questionnaies were analyzed. The educational needs of the training program were calculated by using the Borich(1980)'s needs assessment formula. The evaluating model was developed by the team. Major findings of this study were as follows; First, the training needs of specialized high-school teachers was high. Second, the satisfaction of the training program was high. Third, the overall effectiveness of training programs was high. Fourth, the improvement ideas were divided into four area - 1)The status quo area, 2) the alternatives exploration area, 3) the strategy modifications area, 4) the expected expansion area.

The purpose of this study was to investigate the perception of the scientifically gifted high school students to the research and education (R&E) program. 270 scientifically gifted high school students participating in R&E program were sampled and surveyed according to the R&E' purpose, the process of topic selection, the advantage, and disadvantage of R&E. 4 students among them were interviewed in depth. Students perceived the purposes and advantages of R&E as fostering the scientist' qualifications, providing the research opportunities, and improving the inquiry ability and the disadvantages of R&E as the time consumption in research, the participation as a sideline, and the difficulty of contents. The R&E program was mainly composed of a pre-determined topic, fixed procedures, and expert's settlements in the problem-emerging situation and was not cognitive but technical apprenticeship. In addition, students considered the participation of R&E as a chance of experience about the high techniques and the valuable instruments instead of the improvement on the creative problem-solving ability. The role of mentors in the R&E program is so important that it affects largely on the productive participation and the perceptions of science and scientists.

Mixed connective tissue disease (MCTD) is characterized by diverse symptoms including rheumatoid arthritis, scleroderma, systemic lupus erythematosus, and dermatomyositis, associated with high titers of antibodies to extractable nuclear antigen (ENA), especially anti-ribonucleoprotein (anti-RNP) antibody. Since the first report of 25 cases with MCTD in adults, there have been only a few cases of MCTD reported in children. Here, we report a rare childhood case of MCTD in a 7-year-old girl presenting initially with Raynaud's phenomenon, swollen hands, and ulceration of the right index finger tip followed by alopecia and arthritis during follow-up.

The purpose of this research is to develop a model of teacher education system in u-Learning age. To achieve the purpose, first, the current teacher education system was analyzed. Second, ubiquitous technologies which could be used in future teacher education system were analyzed. Third, functions of ubiquitous technologies supporting communication between the elements of teacher education system were explored based on the analysis of the technologies. Forth, researchers analyzed pre-service teachers' understanding, needs, and demands for the future teacher education system in u-Learning age. The model of teacher education system which is appropriate for u-Learning age was proposed based on the results of analyses. The developed model could help to educate pre-service teachers who will lead the education in u-Learning age.
