본 연구는 예비보육교사가 보육실습이라는 과정에서 프로젝트 접근법에 대한 관심은 어떠하며, 관심변화 여부를 사례중심으로 살펴보는 것을 목적으로 하였다. 이를 위하여 예비보육교사를 대상으로 보육실습 사전과 사후검사를 실시하였으며, 자세하고 구체적인 사실과 연구의 질적인 부분을 찾아보고자 인터뷰하였다. 그 결과, 첫째, 프로젝트에 대한 예비보육교사들의 관심은 전반적으로 무관심으로 나타났다. 둘째, 사전․사후검사 결과, 프로젝트 접근법에 대한 관심수준의 변화가 있었던 사례에서는 관심변화의 패턴도 다양하게 나타났으며, 관심변화가 크게 없었던 사례에서는 개인, 정보관심이 높게 나타났다. 이러한 결과는 프로젝트에 대한 예비보육교사의 관심수준은 보육환경, 보육과정, 실습지도 교사, 예비보육교사의 지각력, 프로젝트에 대한 사전지식이나 교육정도에 따라 다양하게 변할 수 있음을 알게 되었다. The purpose of this study is to analyze the case in which we can identify how the SoC of prospective child care teachers about the project approach changes and why these change appears during the child care practice when we assumpt that for prospective child care teachers to implement the project approach is that they participate in change during child care practice. In Case K, the SoC of the prospective child care teacher moves from Stage 0 awareness to Stage 2, Stage 3, Stage 4, and In Case M, the SoC moves from Stage 0 to Stage 1. In Case P, the SoC moves from Stage 1 to Stage 2, Stage 3, and in Case S, the SoC isn't changed. Above this, we identify the SoC of prospective child care teachers. Case K, M, and P changes SoC after child care practice, but Case S doesn't change. the reason why there is a difference is the mindset of prospective child care teachers. Anyone who wants to accomplish specific purposes can deal with diverse changes with flexibility, but others can easily have an effect on the changes. We suggest that instructor in organization for prospective child care teachers’ education need to have a class for prospective child care teachers to put theory into practice, give direct facilitation and intervention in the field to prospective child care teachers, make a learning environment for prospective child care teachers to make good use of teaching materials and instrument, develop guidebook for project approach and give support to prospective child care teachers.

Background/Aims: Epstein-Barr virus (EBV) is involved in the pathogenesis of angioimmunoblastic T-cell lymphoma (AILT), but its precise role and prognostic impact are not clear. This study aimed to evaluate the incidence of EBV-postitivity in the tumor and bone marrow (BM) samples from AILT patients, and their correlations with the clinical variables and patient survival. Methods: Seventy AILT cases were identified over a period of 8 years. Twenty seven cases were investigated for their EBV tumor status, and 10 BM samples of these patients were investigated for their EBV status with using in situ hybridization (ISH). EBV PCR was performed for the BM mononuclear cells in 8 cases. Results: Among the 27 tumor specimens, ten (37%) were EBV-positive. Only CD20-negativity in tumor correlated with the EBV-positivity (p=0.035). In 13 (48%) patients, gross tumor involvement was recognized by hematoxylin-eosin staining at the time of diagnosis. Among the 10 patients who had additional BM slides available, there were 3 with BM involvement, and none showed EBV positive results on ISH. EBV PCR of the BM mononuclear cells revealed one-positive case among 8 patients. This patient was negative for both BM involvement and EBV ISH. The median overall survival of the 25 treated patients was 48.9 months (95% CI: 18.6~79.2 months). Neither overall survival nor progression-free survival was related with EBV-positivity of the tumor. Conclusions: EBV-positivity of tumor had no impact on the prognosis of AILT patients.
