Development of a Language Learners’ Reading Fluency Test with regard to Pre/Post Test Design
박아영 사단법인 인문사회과학기술융합학회 2015 예술인문사회융합멀티미디어논문지 Vol.5 No.5
To increase the benefit of a pre/post test design, the validity and reliability of the research should be carefully considered, since a pre/post test design require tests to be conducted multiple times. The current study developed a reading fluency test with a pre/post test design that aimed to measure the effect of the intervention on English learners. The developed reading fluency test was piloted twice and subsequently revised according to the pilot test results. According to the results of the pilot studies, the current study a) increased the test validity by measuring not only reading rate but also comprehension and b) strengthened the test reliability by using different reading texts that took into consideration the comparability of the readability of the text used across the pre and post tests.

Purpose: This study aimed to compare the degree of gastric food stasis and following body fat changes after laparoscopic subtotal gastrectomy (LSTG) versus open subtotal gastrectomy (OSTG). Materials and Methods: For 284 consecutive gastric cancer patients who underwent subtotal gastrectomy (213 LSTG and 71 OSTG), the one-year follow-up CT images were reviewed retrospectively. The characteristics of gastric stasis was divided into 5 degrees (0, no residue; 1, small secretion; 2, poorly-defined amorphous food; 3, well-delineated measurable food; 4, bezoar-like food). The residual food volume was calculated for the patients with degree 3 or 4 gastric stasis. Postoperative visceral, subcutaneous, and total fat changes were measured on CT and were correlated with the residual food volume. Results: The LSTG group showed higher degrees of gastric stasis [degree 3 (LSTG, 15.0%; OSTG, 9.9%), degree 4 (LSTG, 6.5%; OSTG, 2.8%)] (p = 0.072). The mean residual food volume of the LSTG group was larger than that of the OSTG group (13779 cc versus 6295 cc) (p = 0.059). Postoperative abdominal fat change was not significantly different between the 2 groups and was not correlated with the residual food volume. Conclusion: LSTG tends to develop gastric stasis more frequently compared with OSTG, but gastric stasis might hardly affect the postoperative body fat status.

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/nonneoplastic lesions in fifty-three cases and fatted in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.
치매전문요양보호사의 치매 지식, 공감 및 치매에 대한 태도

The purpose of this study was to examine the relationships among dementia knowledge, empathy, attitudes toward to dementia in caregivers of older adults with dementia. Data were collected 147 caregivers who worked in long term care centers. The self-report questionnaire was used for data analysis. SPSS Win. 21.0 was used to analyze data via descriptive statistics, Pearson correlation coefficient, and multiple regression. The mean score of dementia knowledge was 20.18±3.58 out of 30, and the means of empathy was 82.12±9.68 out of 105 and the means of dementia attitudes was 96.45±13.72 out of 140. Attitudes toward dementia in caregivers differed significantly depending on their age, motivation of job. Attitudes also had a positive correlation with dementia knowledge and empathy. The most significant preditors of attitudes were empathy, job of motivation and age. These factors explained 33.0% of the variance for attitudes toward dementia. Above results suggest that dementia education programs depending on age, job of motivation, and empathy level is needed. 본 연구는 치매전문요양보호사의 치매에 대한 태도에 영향을 미치는 요인을 확인하여 치매돌봄서비스 질을 향상시킬 수 있는 근거자료를 마련하기 위한 서술적 조사연구이다. G시와 J도에 소재한 요양센터에 근무하는 치매전문요양보호사 147명을 대상으로 하였으며, 구조화된 설문지로 설문을 수집하였다. 수집된 자료는 SPSS Win 21.0을 이용하여, 기술통계, Pearson correlation coefficient, Multiple linear regression 등의 방법으로 분석하였다. 연구결과 치매지식 점수는 30점 만점에 평균 20.18±3.58점, 공감은 105점 만점에 평균 83.12±9.68점, 치매에 대한 태도는 140점 만점에 평균 96.45±13.72점이었다. 치매에 대한 태도는 연령, 직업동기에서 유의한 차이를 나타내었으며, 지식 및 공감과 모두 양의 상관관계가 있었다. 태도에 영향을 미치는 주요변인은 공감으로 설명력은 28.6%였다. 연구결과를 토대로 요양보호사의 연령, 동기, 공감에 따른 치매전문교육프로그램을 실시할 것을 제언한다.
A Case of the Vibrant Soundbridge Stapes Coupler in Patients with Mixed Hearing Loss
박아영,전주현,문인석,최재영 대한청각학회 2014 Journal of Audiology & Otology Vol.18 No.2
The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or surgical complications. A 65-year-old man with bilateral mixed hearing loss and chronic otitis media underwent vibroplasty with a stapes clip coupler. Speech discrimination scores in both quiet and noise environments showed better functional gain with the VSB than with the use of a conventional hearing aid. The results of the present case show the feasibility of implanting a VSB with a stapes coupler in patients with mixed hearing loss due to chronic otitis media.
