  • The purpose of this preliminary study was to develop a measurement for assessing risk factors for falling in community-dwelling elderly persons. Rasch analysis and principal component analysis were performed to examine whether items on the Activities-Specific Balance Confidence (ABC), assessing self-efficacy, and items on the Berg Balance Scale (BBS), assessing balance function, contribute jointly to a unidimensional construct in the elderly. A total of 35 elderly persons (4 men, 31 women) participated. In this study, each item of ABC (16 items) and BBS (14 items) was scored on a 5-point ordinal rating scale from 0 to 4. The initial Rasch and principal component analysis indicated that 3 of the ABC items and 2 of the BBS items were misfit for this study. These 5 items were excluded from further study. After combining ABC and BBS, Rasch and principal component analyses were examined and finally 23 items selected; 12 items from ABC, 11 items from BBS. The 23 combined ABC-BBC items were arranged in order of difficulty. The hardest item was 'walk outside on icy sidewalks' and the easiest item was 'pivot transfer'. Although structural calibration of each 5 rating scale categories was not ordered, the other three essential criteria of Linacre's optimal rating scale were satisfied. Overall, the ABC-BBS showed sound item psychometric properties. Each of the 5 rating scale categories appeared to distinctly identify subjects at different ability levels. The findings of this study support that the new ABC-BBS scale measure balance function and self-efficacy. It will be a clinically useful assessment of risk factors for falling in the elderly. However, the number of subjects was too small to generalize our results. Further study is needed to develop a new assessment considering more risk factors of falling in elderly.

  • The purpose of this study was to develop and validate a scale for the multidimensional assessment of work-family spillover in working couples with children. The subjects of this study were working wives and husbands with children in Daegu. Two surveys were administered, eliciting 243 respondents and 227 respondents, respectively. Then a series of tests were run to analyze the data, including item-to-total correlation, Cramer's V coefficients, item discrimination, Cronbach's ${\alpha}$, and exploratory and confirmatory factor analysis. The results yielded that, first, a preliminary 102 items were developed on the basis of the literature review, and this was narrowed down to 72 items selected with the help of experts. Through preliminary, primary and secondary survey analysis, the scale for the multidimensional assessment of work-family spillover was developed and validated, with a 36 items scale, 18 items for work to family spillover and 18 items for family to work spillover. Furthermore, the scale constructed three spillover processes - time interference, energy depletion, and psychological distraction - and consisted of four different domains of family life into which spillover occurs - namely marital relationship, parent-child relationship, leisure, and housework. The internal reliability was evaluated to show a confidence range of .85 ~.92 for each factor.

  • While noticing that there is insufficient interest in the assessment of EFL learners' vocabulary levels or sizes, the researchers developed two tests identical in form (Forms A and B) to assess the lexical knowledge of Korean university learners at the $1^{st}{\sim}10^{th}$ 1,000 word bands by adapting a pre-established vocabulary levels test (VLT). Of equal concern was to investigate if the VLT was equally a valid and reliable instrument to be used on measuring the lexical knowledge of EFL learners. The participants were 804 university freshmen enrolled in a General Education English Course from four different colleges. The learners were asked to respond to either Form A or B. While scores generally fell towards the lower frequency bands, multiple regression found the Korean College Scholastic Ability Test (CSAT) to be a significant variable for predicting the learners' vocabulary sizes. From a methodological perspective, however, noticeable differences between Forms A and B could be found with item response theory analysis. The findings of the study provide suggestions on how future VLT for testing EFL learners may have to be redesigned.

  • The results which are from naturalness assessment and visual assessment was examined to accomplish a classification, a conclusion, a comparison and an analysis. Also statistical test was examined to identify applicability of the survey to other rivers according to the result of visual assessment. As a result of naturalness assessment and visual assessment, evaluation rate of Geumho river is the highest rank of the grade as 2.5. Also t-test was examined to apply items of visual assessment at other rivers through differences in means of river naturalness rates from which visual assessment results. Most of differences in means of river naturalness rates are significant. Thus assessment criteria can be applied to other rivers to find out unique characteristics because each item has independent characteristics.

  • Objective: The purpose of this study is to develop new balance evaluation index that can discriminate fall risk factors and provide effective interventions for healthy elderly. In order to conduct this study, the balance assessment tools (TUG, mCTSIB, OLST, FRT and BBS) currently used in clinic were re-evaluated using biomechanical analysis. Method: The participants were healthy elderly people over 65 years old, n=26, age: 69.31±3.13 years; height: 154.00±4.12 cm, body weight: 56.13±6.04 kg. The variables are length of CoM-BoS, length of CoP-BoS, range of CoP, mean distance of CoP, mean frequency of CoP, root mean square of CoP, joint angle, ASM (%SL), CoP-CoM angle. Results: As a result of this study, the following items were included in the list of new balance evaluation index for the healthy elderly, showing differences in the biomechanical evaluation based on the clinical evaluation (Inclusion list: TUG, OLST, 8th assessment item of BBS (reaching forward with outstretched arm), 11th item (turning 360 degrees), 13th item (standing with one foot in front), 14th item (standing on one foot)). Conclusion: Based on the results, the new balance evaluation index for the healthy elderly determined through this study can be used to prevent the fall by evaluating the balance ability in various situations that can be experienced in the normal daily life of the healthy elderly.

  • 이 연구는 고등학교 생명 과학 I의 지필평가 실태를 조사하기 위하여 일반계 고등학교 10개교를 임의로 선정하여 2013학년도 생명 과학 I의 문제지 33부(선택형 문항 690개, 서답형 문항 162개)를 분석하였다. 문항에 대해서는 Bloom의 신 교육목표 분류체계의 틀과 국가수준 학업성취도 평가의 과학과 평가틀에 근거하여 분류하였다. 선택형 문항의 경우 실제 정답률과 이원목적분류표에 제시된 난이도를 비교하였고, 서답형 문항의 경우 문항유형에 따른 문항 수와 배점을 비교하였다. 서답형 문항 중 서술형 문항에 대해서는 반응의 허용 정도, 자료 제시 여부, 출제 형식에 따라 구분하였다. 지필평가 문항 분석 결과, 서답형 문항의 비율이 19.0%로 선택형 문항의 비율(81.0%)보다 낮았다. Bloom의 신 교육목표 분류체계에 의한 분석 결과, 지식 차원에서 '개념적 지식'에 해당되는 문항이, 인지과정 차원에서 '이해하다'에 해당되는 문항이 많았다. 국가수준 학업성취도 평가의 과학과 평가틀에 의한 분석에서 '지식' 영역에 해당되는 문항이 '탐구' 영역에 해당되는 문항보다 약 9배 많았다. 선택형 문항에서 이원목적분류표에 제시된 난이도와 실제 정답률을 비교한 결과, 일치하는 비율은 41.5%였다. 서답형 문항의 유형에 따른 문항 수의 비율을 비교한 결과, 단답형 문항의 비율이 34.0%였고, 그리기 문항은 '세포와 생명의 연속성' 단원에서 주로 출제가 되었다. 서술형 문항에서 반응의 허용 정도에 따라 분류한 결과, 모두 '응답 제한형'에 해당되었고, 그 중 '내용범위 제한형'(67.3%)에 해당되는 문항이 가장 많았다. 그리고 자료 제시여부에 따라 분류한 결과 '자료 제시형'(65.4%)에 해당되는 문항이, 출제 형식에 따라 분류한 결과 '지식 서술형'(80.4%)에 해당되는 문항이 가장 많았다. 이 연구 결과를 통하여 학교 현장에서 '탐구' 영역에 해당되는 문항을 더 많이 출제할 필요가 있으며, 서술형 문항의 실제적 비중을 높이면서, 다양한 유형으로 출제할 필요가 있다고 생각된다.
