  • Objectives: The aim of this study was to assess the influence of operator experience level on the lifespan of the WaveOne Primary file (Dentsply Maillefer, Ballaigues, Switzerland) in extracted teeth. Materials and Methods: Moderately curved canals of extracted maxillary and mandibular molars were randomly distributed into 2 groups: experienced and inexperienced operators. Ten files were allocated to each group (n = 10). Each canal was prepared until the working length was reached, and the same file was used to prepare additional canals until it separated. The number of canals prepared before file separation was recorded. The fragment length of each file was measured, and the location of the fragment in the canal was determined. Data were statistically analysed using the independent 2-sample t-test. Results: The 2 operators prepared a total of 324 moderately curved canals of maxillary and mandibular molars. There was no significant intergroup difference in the mean number of canals prepared (p = 0.27). The average lifespan of the WaveOne Primary file was 17.1 and 15.3 canals, and the longest lifespan was 25 and 20 canals, when used by experienced and inexperienced operators, respectively. There were no statistically significant intergroup differences in separated fragment length and location. Conclusions: Within the limitations of this study, operator experience level appears to have no effect on the lifespan of the WaveOne Primary file in preparation of moderately curved canals. Single teeth with multiple canals can be prepared safely even by a novice operator by using a single file.

  • Immune thrombocytopenia (ITP) is a disease in which thrombocytopenia occurs because of immune-mediated platelet destruction and decreased platelet production. Although many pediatric patients with ITP experience spontaneous remission or reach remission within 12 months of first-line therapy, approximately 20% progress to chronic ITP. Patients who do not respond to first-line treatment or experience frequent relapses are of great concern to physicians. This review summarizes recent treatments for second-line treatment of pediatric chronic ITP.

  • Purpose: This study was conducted to examine and compare satisfaction with Korean health care services for Americans, Chinese and Russians who resided in Korea. Methods: A questionnaire was distributed to 252 participants (81 Americans, 89 Chinese, 82 Russians). Three focus group interviews were subsequently conducted in order to obtain a greater understanding of participants' experience and perspectives. Results: The average satisfaction score was 3.09, with Americans and Russians showing significantly higher scores than Chinese. Overall, participants reported higher satisfaction in 'Facility', 'Quality of care' and 'Nursing services' as opposed to 'Information/education'. 'Care with cultural respect' as well as communication related services. Data from the focus group interviews were categorized into 12 sub-categories, 7 categories and 2 themes. The two themes were common experience and contrasting experience. Common experience included 4 categories, 'Quality of care', 'Hospital facility and health care system', 'Language barrier' and 'Information and education'. Contrasting experience included 3 categories, 'Medical cost', 'Health care personnel' and 'Accessibility'. Conclusion: Results of this study provide basic knowledge on foreign residents' satisfaction and experience with Korean health care services. Further research is needed with foreigners from different cultural backgrounds. Administrative and educational efforts are required to improve communication skills and cultural competency.

  • 본 연구의 목적은 상징적 상호작용론적 견해에 바탕을 둔 근거이론 방법을 이용하여 간호대학생의 전공 융합한 해외 단기연수 경험에 대한 실체이론을 도출하고, 해외 단기연수가 나아가야 할 방향을 조명하는데 있다. 연구결과를 보면 참여자들은 연수 후 경험으로 내 안의 또 다른 '나'를 발견하고 더 넓은 세상으로 나가고자 하는 열망이 강하게 생기면서 삶에 대한 태도를 변화하기 시작하였고 이는 자아성숙으로 나타났다. 그러나 일부 참여자는 현실에 짓눌려 열망을 내려놓고 예전 삶으로의 회귀를 나타내기도 하였다. 본 연구결과를 토대로 볼 때, 전공 융합한 해외 단기연수 후에는 반드시 추후 프로그램을 운영하여 긍정적으로 변화된 열망, 동기, 자신감 등을 강화 유지시켜 주는 것이 필요하고, 개인 성향에 따른 맞춤형 추후 프로그램을 운영하는 것이 요구된다. 또한 추후 프로그램 운영 시 연수에 참여한 학생들에 대한 주기적인 평가를 통해 추후 시점마다 심리적 또는 교육적 지지자원을 분배 투입하는 것이 필요하다.
