Acknowledging the value of personalization as an effective teaching and learning device to enhance competence in communication, this study aims to examine the 2015 Revised Primary English Curriculum and textbooks to investigate the contents and activities related to personalization. The study examined the curriculum related to speaking and writing for the contents that can be linked to personalization. It also examined three most popular textbook series of grades 3 through 6 to analyze the frequency, language function areas, the periods of a unit, and the types of personalization activities. The results of the study shows that personalization-related contents appear throughout the curriculum. However, more comprehensively and systematically written curriculum is desired in order to provide elementary learners a more personalization-rich learning environment. In terms of the frequencies, language function areas, and the periods of a unit of personalization activities, there was also room for improvement. Suggestions for writing a more comprehensive and systematic curriculum are provided and recommendations are made toward providing a learning environment that is more enriched in personalization activities, more balanced in speaking and writing, and more varied in the periods of units that personalization activities are utilized.

The aim of this study was to investigate effects of English classes using AI PengTalk on English pronunciation ability of elementary students and affective factors of English pronunciation. Forty-two participants (5th graders) were divided into experimental (n = 21) and control (n = 21) groups. Their pronunciation scores of pre-and post-pronunciation tests focusing on evaluating segmentals, intonation, stress and rhythm, and speech rate were quantitatively analyzed. Data from a questionnaire about affective factors of English pronunciation including a journal writing were quantitatively and qualitatively analyzed. Findings of this study indicated that: 1) there were statistically significant differences in English pronunciation abilities between the two groups, 2) there were also statistically significant differences in affective factors such as self-confidence, interests, and attitudes, and 3) students indicated in their responses to open-ended questions and their selfevaluation journal that AI PengTalk classes helped them speak English well and enhanced their self-confidence, interests, and positive attitudes in their pronunciation. These results suggest that AI PengTalk need to be actively used in schools as a good tool for developing students’ English pronunciation abilities and that primary school teachers should focus on their pronunciation teaching for promoting students’ self-confidence, interests, and attitudes towards pronunciation learning.

The empathy ability test was conducted after program to verify effect. The data were analyzed by using the Mixed ANOVA, and reviewed the group members' experience report and counselor's contents of observation. The results obtained through this research are as follows. First, It was found that there were significant differences in changes between the experimental group which participated in a group counseling program utilizing audio-visual media to enhance empathy ability and the control group. Second, It was also found that there were significant differences in changes in the subordinate domains of empathy ability such as perspective-taking, fantasy, empathic arousal and empathic concern between the experimental group and the control group. The results of the analysis of the group members’ experience reports and the counselor’s observations showed that this program had positivity on the enhancement of the empathy ability. The implications of this research were that a group counseling program which can be operated in a class for upper grade elementary school students were developed and the visual media technology reflecting the changes in modern society was applied. In particular, this study holds meaning as it confirmed enhancing empathy ability, in which the empathy ability was subdivided into subordinate domains such a cognitive and emotional aspects, and program was provided. 이 연구는 초등학교 고학년을 대상으로 공감능력 향상을 위한 영상매체 활용 집단상담 프로그램을 구안하고 그 효과를 검증하는데 목적이 있다. 연구대상은 J시에 소재한 초등학교의 6학년을 대상으로 공감능력 검사를 실시하고 2개 학급을 선정하여 실험집단과 통제집단으로 구성하였으며 본 연구에서 구안한 영상매체 활용 집단상담 프로그램을 실험집단에 적용하였다. 프로그램의 효과 검증을 위해 프로그램 실시 후 공감능력 검사를 실시하고, 혼합변량분석(Mixed ANOVA)의 방법으로 분석하였으며, 집단원의 경험보고서와 상담자의 관찰 내용을 검토하였다. 연구결과 첫째, 집단상담 프로그램에 참여한 실험집단의 공감능력의 변화가 통제집단에 비해 유의하게 높은 것으로 나타났다. 둘째, 공감능력의 하위영역인 조망취하기, 상상하기, 공감적 각성, 공감적 관심에서 실험집단의 변화가 통제집단에 비해 유의한 차이를 보였다. 또한 집단원의 경험보고서와 상담자의 관찰내용을 검토한 결과, 본 프로그램이 공감능력 향상에 긍정적이었음을 확인할 수 있었다. 이 연구는 초등학교 고학년을 대상으로 학급에서 운영할 수 있는 집단상담 프로그램을 개발한 것으로, 방법적으로 현대사회의 기술변화를 반영한 영상매체를 활용하였으며 특히, 공감능력을 인지적․정서적 측면으로 구분한 하위요소에 개입하여 공감능력의 향상을 확인하였다는데 의의가 있다.

진공자외선 여기에 의한 YAGG:Ce³⁺ 형광체의 광발광 특성에 미치는 Al₂O₃ 나노입자 원료의 결정상의 영향

우미혜,최성호,정하균,Wu, Mi-Hye,Choi, Sung-Ho,Jung, Ha-Kyun 한국재료학회 2012 한국재료학회지 Vol.22 No.4

$Ce^{3+}$-doped yttrium aluminum gallium garnet (YAGG:$Ce^{3+}$), which is a green-emitting phosphor, was synthesized by solid state reaction using ${\alpha}$-phase or ${\gamma}$-phase of nano-sized $Al_2O_3$ as the Al source. The processing conditions and the chemical composition of phosphor for the maximum emission intensity were optimized on the basis of emission intensity under vacuum UV excitation. The optimum heating temperature for phosphor preparation was $1550^{\circ}C$. Photoluminescence properties of the synthesized phosphor were investigated in detail. From the excitation and emission spectra, it was confirmed that the YAGG:$Ce^{3+}$ phosphors effectively absorb the vacuum UV of 120-200 nm and emit green light positioned around 530 nm. The crystalline phase of the alumina nanoparticles affected the particle size and the luminescence property of the synthesized phosphors. Nano-sized ${\gamma}-Al_2O_3$ was more effective for the achievement of higher emission intensity than was nano-sized ${\alpha}-Al_2O_3$. This discrepancy is considered to be because the diffusion of $Al^{3+}$ into $Y_2O_3$ lattice is dependent on the crystalline phase of $Al_2O_3$, which affects the phase transformation of YAGG:$Ce^{3+}$ phosphors. The optimum chemical composition, having the maximum emission intensity, was $(Y_{2.98}Ce_{0.02})(Al_{2.8}Ga_{1.8})O_{11.4}$ prepared with ${\gamma}-Al_2O_3$. On the other hand, the decay time of the YAGG:$Ce^{3+}$ phosphors, irrespective of the crystalline phase of the nano-sized alumina source, was below 1 ms due to the allowed $5d{\rightarrow}4f$ transition of the $Ce^{3+}$ activator.

A Comparative Study of Diet in Good and Poor Glycemic Control Groups in Elderly Patients with Type 2 Diabetes Mellitus

우미혜,박수진,우정택,조여원 대한당뇨병학회 2010 Diabetes and Metabolism Journal Vol.34 No.5

Background: Identification of dietary patterns is important for glycemic management in elderly patients with type 2 diabetes mellitus (T2DM). Methods: Elderly T2DM patients (> 65 years of age, n = 48) were categorized based on their concentration of glycated hemoglobin (HbA1c). Subjects with HbA1c levels below 7% were placed in the good control (GC) group and those with HbA1c levels equal to or above 8% were placed in the poor control (PC) group. Anthropometric data, blood parameters, and dietary intake records were compared between the groups. Statistical analysis included Student’s t-test, chi-square test, and Pearson correlation coefficient test. Results: Anthropometric data, including body mass index (24.7 ± 2.9 kg/m2), did not differ between the GC and PC groups. Significant abnormalities in blood glucose levels (P < 0.01), lean body mass (P < 0.01), and plasma protein and albumin levels (P < 0.05, P < 0.01) were found in the PC group. In contrast to the GC group, the PC group depended on carbohydrate (P = 0.014)rather than protein (P = 0.013) or fat (P = 0.005) as a major source of energy, and had a lower index of nutritional quality for nutrients such as protein (P = 0.001), and all vitamins and minerals (P < 0.001, 0.01, or 0.05 for individual nutrients), except vitamin C, in their usual diet. Negative correlations between HbA1c levels and protein (r = -0.338, P < 0.05) or fat (r = -0.385, P < 0.01)intakes were also found. Conclusions: Healthcare professionals should encourage elderly diabetic patients to consume a balanced diet to maintain good glycemic control.

7대 분야 자격재설계 종목의 NCS 수준의 타당성 분석연구

강석주,우미혜,박영삼 한국공학교육학회 2016 공학교육연구 Vol.19 No.1

New occupational qualification system built on NCS(National Competency Standard) aimed to induce industries, the final appliers of qualification, to play a leading role in designing qualification and to spontaneously apply such qualification standard to employment and promotion so as to reinforce universality of qualification. In this study, we verified the validity of NCS level of qualification categories for 130 occupational fields by redesigning NCS-based new occupational qualification system with a focus on 7 major areas, including mechanical field, which were found to have wide-ranging social ripple effect throughout society and high acceptability in 2014. The results of study on suitability at qualification level suggested the followings: First, there is a difference in number of competency units for each qualification category, depending on area. New qualification covering 7 major areas included 15.3 competency units for each qualification category, which exceeds the number of competency units(about 10 units) in subdivided NCS. By field, some difference was found with 7.9 competency units for cultural field and 22.6 competency units for information and communication area. Second, preference above normal level was observed in the criteria, procedure and method for determining qualification redesigning. However, preference below normal level was exhibited in connection with possibility of linkage with overseas qualifications, although preference was above normal level in relation to the suitability of design/qualification level and qualification categories based on lifelong career development path within scope of NCS as the criteria for determining the redesign of qualification categories. Second, we compared NCS level and SC(Sector Council level, and the results showed that NCS level was found to be somewhat well-defined. For the qualifications with different definitions, it was deemed difficult to determine superiority between NCS level and SC level. However, majority opinion indicated that it would be desirable to follow NCS level because NCS was created through collection of opinions for a prolonged period

The purpose of this study was to investigate the employment effects of vocational training to unemployed if applicable NCS. To this end, it was obtained completion personnel(each 39,974 persons, 125,682 persons) and employment personnel(each 21,487 people, 57338 people) of training courses applied the NCS and not applied the NCS among the unemployed training courses supported Ministry of Employment and Labor, and a Meta-Analysis was conducted, which analyzed risk ratio to calculate the effect size of the dichotomous data according to employment status. The finding of the study were as follows. First, NCS training courses' employment(8.13%) and the employment effect size(1.175 times) appeared higher than non-NCS training courses'. A simple employment rate difference between the NCS and non-NCS training courses can not properly verify the employment effects of the NCS, but the NCS training courses may have a statistically significant effect size through the employment effect size analysis compared to non-NCS training courses, it was verified that NCS training courses were more likely to 1.175 times greater than the non-NCS training courses. Second, classification showing over the middle employment effect size of NCS training courses is six out of a total of 17 classifications utilized in the analysis, classification showing the small effect size is 8, the effect size is almost the same classification 1, non-NCS larger effect size classification of training courses were presented in two. Third, according to the training business, NCS's employment effect size of the general unemployed training was 1.032, while NCS's employment effect size of the National Infrastructure and Strategy Industries training was slightly higher with the 1.084. 이 연구의 목적은 실업자 훈련과정의 국가직무능력표준(National Competency Standards, 이하 ‘NCS’) 적용 여부에 따른 취업 효과크기를 구명하는 데 있다. 이를 위해 고용노동부가 지원하는 실업자훈련 중에서 NCS를 적용한 NCS 기반 훈련과정과 비NCS 훈련과정의 수료 인원(각 39,974명, 125,682명) 및 취업 인원(각 21,487명, 57,338명)을 확보하여, 취업여부에 따른 이분형 데이터의 취업 효과크기를 계산하는 이벤트 발생 비율(RR: Risk Ratio)을 적용하는 메타분석을 실시하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, NCS와 비NCS 훈련과정의 취업률 및 취업 효과크기를 분석한 결과 NCS 기반 훈련과정의 취업률(8.13%)과 취업 효과크기(1.175배)가 더 높게 나타났다. NCS와 비NCS 훈련과정 간의 단순한 취업률 차이로는 NCS의 취업 효과성을 제대로 검증할 수 없지만, 취업 효과크기 분석을 통하여 NCS 기반 훈련과정이 비NCS 훈련과정에 비해 통계적으로 유의한 효과크기를 지니고 있고, NCS 기반 훈련과정이 비NCS 훈련과정에 비해 1.175배 취업할 확률이 더 큼을 검증하였다. 둘째, 분류별로 NCS 기반 훈련과정의 취업 효과크기가 중간 이상 나타난 분류는 분석에 활용된 총 17개 분류 중 6개, 작은 효과크기를 나타낸 분류는 8개, 효과크기가 거의 유사한 분류는 1개, 비NCS 훈련과정의 효과크기가 더 크게 나타난 분류는 2개로 나타났다. 셋째, 훈련 사업별로 내일배움카드의 NCS 기반 훈련과정 취업 효과크기는 1.032인 반면, 기간전략의 NCS 기반 훈련과정 취업 효과크기는 1.084로, 기간전략의 NCS 기반 훈련과정 취업 효과크기가 조금 더 높게 나타났다.

This study as a follow-up to the completion of the development NCS-based new occupational qualification and prototype questions for 'Work and Learning in Parallel' qualification, aimed to analyze the results of a pilot test of prototype questions developed for the 'Work and Learning in Parallel' qualification. A pilot test was conducted with current industrial workers using 45 prototype questions developed for the 'Work and Learning in Parallel' qualification for the four fields of electric & electronic, material, construction, and design. After the test, two written reviews (the first for written evaluation, and the second for field evaluation) were completed on the appropriateness of the questions, answers, question difficulty, evaluation methods, distribution of marks, evaluation time, and precautions for evaluation. The results of the final analysis of the pilot test. The first review (for written evaluation) revealed problems like a large deviation in expected scores, the omission and ambiguous relevance of competency units, and an insufficient number of questions, and suggested the adjustment of the distribution of marks, and the modification of questions demanding fundamental answers. The second review (for field evaluation) pointed out the lack of universality in question development, and required the modification of questions not reflecting field realities, the development of specific and creative questions, and a review of evaluation methods. This study further emphasized the necessity for a competent authority responsible for the 'Work and Learning in Parallel' qualification on behalf of the industry, and institutional support for the early settlement of the qualification system. 이 연구는 NCS 기반 신 직업자격 검정기준과 일학습병행자격 문제원형 개발의 완료에 대한 후속과제로서, 일학습병행자격에서 개발된 문제원형의 파일럿 테스트 결과를 분석하여, 일학습병행자격의 효율적 운영을 위한 정보제공을 목적으로 실시되었다. 전기전자, 재료, 건설, 디자인 4개 분야에서 개발된 45개 종목의 일학습병행자격 문제원형을 활용하여, 산업현장에 근무하는 재직근로자를 대상으로 파일럿 테스트를 실시하고, 문제원형에 대하여 문항의 적절성, 정답의 적절성, 난이도의 적절성, 평가방법의 적절성, 배점의 적절성, 평가시간의 적절성, 평가시 유의사항 적절성 등에 대한 검토내용을 1차 지필평가용과 2차 실무평가용으로 구분하여 작성하도록 하였다. 45개 종목에 대한 파일럿 테스트와 문제원형 검토내용을 취합한 자료를 최종 분석한 결과는 다음과 같다. 먼저 1차 지필평가에 대한 의견은 예상점수에 대한 편차가 높고, 능력단위 누락 및 관련성이 모호하며, 문항수가 충족되지 않고, 평가시간에 대한배점 조정의 필요성, 답을 제시할 때 근원적 답의 요구 등의 이유로 보완이 필요한 것으로 나타났다. 2차 실무평가에 대한 의견은 현장 내용과의 불일치 문항, 구체적으로문항을 개발하여 제시할 필요, 창의적인 문항으로 보완 필요, 현장성과 다양성 필요, 문형개발에 대한 보편성 필요, 평가 방법에 대한 재검토 필요 등으로 보완이 필요한것으로 나타났다. 이 연구의 결과, 일학습병행자격 문제원형의 완성도와 현장성이 떨어지므로 이를 강화하기 위해서는 해당 산업계를 대표해서 일학습병행자격 문제출제 업무를 전담해서수행할 부서를 지정하고, 자격시스템의 조기 정착을 위해서 제도적인 장치가 마련되어야 함을 제안하였다.
