이 연구의 목적은 경력 체육교사가 초임 체육교사 멘토링에 멘토로 참여하면서 겪는 경험을 기술하고 그 교육적 의미를 찾는데 있다. 이 연구는 내러티브 연구 방법을 사용하였고 연구 참여자는 유목적 표집 중 결정적 사례 표집법에 의해 선정되었다. 연구 참여자는 초임 체육교사 멘토링에서 멘토로 참여하는 경력 교사 중 우수한 역량을 가지고 있으며 주위에서 좋은 평판을 받고 있는 체육교사이다. 자료는 연구 참여자와의 인터뷰와 멘토링 대화 녹취록과 문서를 중심으로 수집하였다. 초임 체육교사 멘토링에서 멘토의 경험은 다음과 같이 4가지의 교육적 의미로 해석할 수 있었다. 첫째, 두 경력교사는 멘토링을 통해서 멘티에게 ‘선한 영향력’을 주고 싶다는 마음이 멘토링 참가의 동기이자 목표로 작용하였다. 둘째, 멘토의 경험을 통해 멘토와 멘티 간의 ‘조화와 균형 그리고 거리’가 성공적인 멘토링을 위한 중요한 요인임을 알 수 있었다. 셋째, 멘토링은 심리적인 만족감과 자신들의 경험들을 되돌아볼 수 있는 성찰의 시간과 또 다른 도전을 준비할 수 있게 하는 ‘유의미한 경험’으로 귀결되었다. 넷째, 자신이 경험하고 생각했던 멘토링이 아닌 멘토링에 대한 인식을 변화시킨 멘토링을 재조명하는 경험이 되었다. 이러한 연구결과를 통해 멘토링에서 멘토에 대한 포괄적인 이해와 초임 체육교사를 위한 멘토링 방향 설정에 도움이 될 것을 기대해본다. The purpose of this study was to conduct an in-depth exploration of the educational meaning of the process of storying telling and the retelling of novice physical education teachers’ experiences of mentoring under experienced teachers during a mentoring program. This study used a narrative study method, and the participants were selected by the definitive case sampling method among the nomadic sampling. The data were collected mainly on interviews with research participants, transcripts of mentoring conversations, and other documents. The meaning of mentor experience for novice physical education teachers as mentoring was as follows. First, the desire of the two experienced teachers to give the mentee a “good influence” through mentoring served as the motivation and goal of mentoring participation. Second, through the mentor experience, it was found that “harmony, balance, and distance” between the mentor and the mentee was an important factor for successful mentoring. Third, mentoring resulted in a sense of psychological satisfaction, a time of reflection to reflect on their experiences, and a ’significant experience' that enabled them to prepare for another challenge. Fourth, it became an experience to re-examine the mentoring, which changed the perception of mentoring, not mentoring that he experienced and thought. It is expected that these results will help in mentoring to comprehensively understand mentors and to establish mentoring directions for novice physical education teachers.

Various materials of artificial bearing surfaces are developed and applied to reduce wear and osteolysis and to improve the survival rate of total hip arthroplasty. The survival rate of artificial joint is affected by mechanical properties and biological response. The wear rate of alternative bearing surfaces as ceramic-on-ceramic, metal-on-metal, highly cross-linked polyethylene decreased significantly compared with conventional polyethylene, but long-term results are still under follow-up and several problems have been unsettled. Particularly acetabular component should be in appropriate position to reduce complications. Each bearing surface should be selected considering age, activity, obesity, underlying disease, and socio-economic state of patients because it has its own pros and cons.

The 2.5 vol% TiNi/6061Al composites were fabricated by permanent mold casting. The microstructures and tensile test for the cold rolled composites with maximum 50% reduction ratio were investigated. In the case of TiNi fiber with 2mm interval in preform, the interface bonding of fabricated composites were good, interface diffusion layer of this composites was made by the mutual diffusion. Transverse section of TiNi fiber was decreased with increasing reduction ratio and longitudinal section of TiNi fiber showed multiple wave phenomenon. And the tensile strength of composites at 38% reduction ratio was the most high. In the case of over 38% reduction ratio, the decrease of the tensile strength was due to TiNi fiber rupture by excess working. The fracture mode was appeared brittle fracture with increasing reduction ratio.

N/A To evaluate the role of hepatobiliary (DISIDA) scan in the diagnosis of biliary obstruction, we studied the clinical characteristics of 9 cases with biliary obstructuon, whose hepatobiliary scans and ultrasonography were not concordant (normal ultrasonography and abnormal hepatobiliary scan). The results were as follows; 1) The main chief complaints (89%) were abdominal pain, especially in RUQ area. The levels of serum bilirubin were elevated in 67% of patients (normal∼5.9 mg/dl) and those of alkaline phosphatase were elevated in 78% of patients (normal∼724 U/L). 2) The final diagnoses were CBD stones (67%), tumor (22%) and 3 cases were associated with C. sinensis. 3) The major obstruction sites were in distal CBD (89%). From the above results we concluded that hepatobiliary scan is a useful diagnostic method of biliary obstruction, especially in distal CBD lesion and early stage, in spite of normal ultrasonography.
