Background and Objectives : This study evaluated the efficacy of combination therapy of proton pump inhibitor (PPI) and steroid inhaler (SI), with or without botulinum toxin injection (BTX) for contact granuloma. Subjects and Methods : Fourteen contact granuloma patients were enrolled in this study. Combination therapy of PPI and SI were used for the first line treatment. When combination therapy was not effective, BTX was performed as the second method. Treatment results were recorded as responsible or non-responsible. Farwell grade, size, history of voice abuse, gender, and reflux finding score (RFS) were compared between responsible group and non-responsible group. Results : Initial response rate was 28.6% after treatment of PPI and SI. BTX was performed on three un-responsible patients. After BTX injection, three patients had complete remission of granuloma. Final response rate was 50.0%. Un-responsible group had significantly higher RFS than responsible group. Conclusion : The efficacy of PPI and SI was limited for contact granuloma in this study. Botulium toxin injection was recommended in early phase when PPI and SI did not effective for contact granuloma. Prospective studies evaluating the effects of PPI and SI are warranted.

본 연구에서는 과학자의 활동에 수반되는 뇌 영역과 과학의 진화적 속성을 바탕으로 개발된 뇌기반 진화적 과학 교수학습 모형을 실제적 과학(authentic science)을 기반으로 한모둠 자유탐구 활동에 적합하게 개정하고, 이 개정된 모형을 적용한 자유탐구 수업이 초등학생들의 과학 관련 태도와 과학 탐구 능력에 미치는 영향을 조사하였다. 개정된 뇌기반 진화적 과학 교수학습 모형에서는 기존 뇌기반 진화적 과학 교수학습 모형의 각 단계 사이에서 느끼는 학생들의 곤란을 줄이고자, 진화적 요소를 적용한 세 단계(다양화, 비교ㆍ선택ㆍ실행, 적용ㆍ확장) 사이에 선택 기준 선정과 적절성에 대한 피드백이라는 두 가지 비계를 추가로 설정하였다. 서울 소재 N 초등학교에 재학 중인 6학년 학생 82명이 본 연구에 참여하였고, 비교반 학생들은 교과서 중심의 자유탐구 수업에 참여하였고, 실험반 학생들은 개정된 뇌기반 진화적 과학 교수학습 모형을 적용한 자유탐구 수업에 참여하였다(각각 2주간 6차시). 수업 전과 후에 TOSRA(Fraser, 1981)와 과학 탐구 능력 검사지(권재술과 김범기, 1994)를 통해 초등학생들의 과학 관련 태도와 과학 탐구 능력에 대한 정량적 데이터를 수집하였고, 관찰지 분석, 면담 등 정성적 방법을 병행하여 정량적 검사지로 명확하게 드러나지 않는 변화나 특성들에 관한 정보를 수집하여 분석하였다. 이를 통해 개정된 뇌기반 진화적 과학 교수학습 모형을 적용한 자유탐구 수업의 과학과 관련한 정의적ㆍ행동적 영역에 대한 효과성을 검증하고, 뇌기반 교육 연구와 초등학생들의 과학 교수학습에 관한 함의들을 논의한다.

We Investigated the current limiting characteristics of the flux-lock type superconducting fault current limiter(SFCL) by fault angles. The flux-lock type SFCL consists of the primary and the secondary copper coils wound in parallel through the iron core and YBCO thin film. In this paper, the current limiting characteristics of the flux-lock type SFCL by fault angles in case of the subtractive and the additive polarity windings were compared and analyzed. The flux-lock type SFCL limited fault current more quickly as the fault angles increased. On the other hand, the initial power burden of the superconducting element during the fault increased as the fault angles increased. In addition, we found that the resistance of the flux-lock type SFCL in case of the subtractive polarity winding was more increased than that of the additive polarity winding. The peak current of the fault current in case of the subtractive polarity winding was larger than that of the additive polarity winding.

Purpose: The purpose of this study was to review the daily practice of inferior vena cava filters (IVCFs) in a tertiary referral center in Korea and to reveal the retrieval rate and the methods for improving it.Materials and Methods: Through the electronic medical record system, a retrospective review was performed on 115 consecutive patients who underwent placement of retrievable IVCFs between February 2000 and January 2011 in Seoul National University Hospital. Results: IVCF placement was done in 115 cases (113 patients). There were 68 men (59.1%), and the mean age was 58.5±15.5 years (range, 10-96 years). The affiliated departments were Vascular Surgery (57 cases, 49.6%), and Internal Medicine (20 cases, 17.4%). Advanced malignancy was the most commonly associated disease (n=30, 26%). The indications for IVCF placement were categorized; absolute indications in 36 cases (31.3%), relative indications in 78 cases (67.8%), and prophylactic use in 1 case (0.9%). The most common indications were thrombolysis/thrombectomy for iliocaval deep vein thrombosis (DVT) (n=55, 47.8). Of the 115 filters, 68 were retrieved (retrieval rate, 59%). The most common cause of non-retrieval was chronic high risk of venous thromboembolism in 24 patients (51%), followed by residual proximal DVT (n=7, 15%), and negligence by unknown reasons (n=6, 13%).Conclusion: To improve the retrieval rate, the number of follow-up losses to vascular specialists must be decreased, which can be achieved by establishment of a dedicated IVC filter clinic, implementation of a filter registry, and regular education for medical teams and patients along with their families.

we compared the operating characteristics between flux-lock type and resistive type superconducting fault current limiters(SFCLs). Flux-lock type SFCL consists of two coils, which are wound in parallel each other through an iron core, and a high-Tc superconducting(HTSC) element is connected with coil 2 in series. The the flux-lock type SFCL can be divided into the subtractive polarity winding and the additive polarity winding operations according to the winding directions between the coil 1 and coil 2. It was confirmed from experiments that flux-lock type SFCL could improve both the quench characteristics and the transport capacity compared to the resistive type SFCL, which means, the independent operation of HTSC element.
