이 글은 2015 교육과정 초등 국어과 교과서의 학습 목표를 대상으로 신 교육목표분류학의 체계에 따라 분석해 봄으로써 학습 목표의 지식 차원과 인지과정 차원의 특성을 파악하고, 이를 바탕으로 향후에 개선할 점을 도출하는 것을 목적으로 하였다. 연구 결과, 첫째, 2015 초등 국어 교과서는 학년군별로 학습 목표가 지식 차원과 인지과정 차원 모두에서 매우 불균형하였다. 둘째, 2015 교육과정 성취기준과 초등 국어 교과서의 학습 목표를 비교해 본 결과, 대체로 교육과정 성취기준의 분포와 교과서 학습 목표의 분포가 비슷했지만 ‘메타인지 지식’은 성취기준의 비중보다 교과서 학습 목표의 비중이 크게 낮았다. 셋째, 2015 초등 국어 교과서의 영역별 학습 목표를 분석한 결과 대체로 4개 영역이 비슷한 비중을 차지한 반면, 문법 영역만이 상대적으로 적은 비중을 보였으며, 영역별 특성에 따라 지식 차원과 인지과정 차원의 비중은 서로 달랐다. 이 결과를 바탕으로 다음과 같이 제안하였다. 첫째, 동일한 학년군에서 인지과정 차원의 구성 비율이 학년별로 비슷하게 안배할 필요가 있다. 둘째, 학년이 올라감에 따라 학습 목표 진술에 위계성을 확보할 필요가 있다. 셋째, 학년별 ‘메타인지 지식’에 대한 비율이 증가하여야 한다. 넷째, 국어과의 하위 영역마다 ‘메타인지 지식’의 비율이 증가하여야 한다. 다섯째, 국어과의 하위 영역별 특성을 살려 학습 목표가 진술되어야 한다. This article analyzes the learning goals of the 2015 elementary school Korean textbooks according to the new taxonomy of educational goals to identify the characteristics of the knowledge dimension and the cognitive process dimension of the learning goals, and based on this, points to improve in the future. The analysis results are as follows; 1. In the 2015 elementary Korean textbooks, the learning goals for each grade level are very unbalanced in both the knowledge dimension and the cognitive process dimension. 2. In general, the distribution of curriculum achievement standards and textbook learning goals were similar, but in ‘metacognitive knowledge’, the proportion of textbook learning goals was significantly lower than that of achievement standards. 3. While the four areas occupied a similar weight, only the grammar area showed a relatively small percentage. Based on these results, the following is proposed; 1. The ratio of cognitive process dimension in the same grade group needs to be equally distributed for each grade level. 2. It is necessary to ensure hierarchy and sequence in the statement of learning goals as the grade level goes up. 3. The ratio of ‘metacognitive knowledge’ by grade level should increase. 4. The ratio of ‘metacognitive knowledge’ should increase for each sub-area of the Korean language subject. 5. Learning goals should be stated taking advantage of the characteristics of each sub-area of the Korean language subject.

「多言語母語の日本語学習者横断コーパス」(International Corpus of Japanese as a Second Language:以下I-JAS)では習熟度の測定ツールとして2つの言語テスト「J-CAT」(今井2015)「SPOT」(小林2015)を用いている。本研究ではこの2つの言語テストの得点からI-JASの1000名の学習者を4つのレベルに分けた。そして、習熟度によって語彙の使用にどのような違いが見られるかを決定木分析で調査した。調査の結果、語種や語彙の難易度や文の長さが習熟度の違いを説明する要素であることが明らかになった。このことが日本語教育の現場にどのような示唆を与えるか考察した。 The International Corpus of Japanese as a Second Language (I-JAS) uses two language tests, J-CAT (Imai 2015) and SPOT (Kobayashi 2015), to determine proficiency. In this paper, we divided the 1000 learners of I-JAS into four levels based on their scores on these two language tests. Then, we used decision tree analysis to investigate how the use of vocabulary differed by proficiency level. The results of the study revealed that word type, vocabulary difficulty, and sentence length were factors that explained the differences in proficiency levels. The implications of these findings for the field of Japanese language education are discussed.

1960년대 독일연방공화국의 교육정책 중앙집중화를 위한 개혁 문제

최재호 ( Choi¸ Jae Ho ) 수선사학회 2021 史林 Vol.- No.78

Germany's federal system has a long history, and education, in particular, was being still regarded as an independent area under the jurisdiction of local state governments. Even when the war had ended in 1945 and the Federal Republic was established in western Germany, the federal government did not have the legal authority to engage in the education policy. It played a very limited role in supporting the state governments according to the ‘Kulturföderalismus’(cultural federalism). However, with the beginning of education reform in the 1960s, the tendency of centralization for unifying the educational system and planning of the education policies at the national level beyond regional limits began to develop. Through the revision of the Constitution in 1969, the federal government was first guaranteed jurisdiction over the education policy and allowed to have the ‘BMBW’(Federal Ministry of Education). Furthermore, the education policy began to be managed in some integrated way by the central government. This study examines the process of reform for the centralization of the education policy, and deals with the controversies and limitations surrounding it.

Objective: We proposed an effective 3D menu manipulation alternative with a usability test. This was performed in a 3D environment with 3D menu and control manipulation methods. Background: As 3D stereoscopic displays became generalized, various 3D applications were being used not just movies, games, but also mobile contents and advertisements. However, when a user interface was designed in a 3D environment, it was lacked that a clear standard and result of an efficiency and usability as like a 2D environment. Method: We implemented 9 kinds of 3D menu types based on 3D menu hierarchies, menu layouts and dimensions. And we extracted 3 representative control types in a 3D environment. We performed usability evaluation with full factorial design for 27 menu alternatives with 2 types of menu manipulation tasks. In this condition, we measured the performance time, subjective discomfort and eye-fatigue. Results: A control type had the significant effect, and the effect of menu types had the different result depending on given tasks. Conclusion: This experiment showed the interaction of menu and control types depended on 3D menu manipulation tasks were significant in a 3D user interface design. Therefore, as a purpose of a 3D menu manipulation task, 3D menu types and control types were should be considered. Application: We supposed this result was should be applied in a 3D menu contents design.

A sensitive, precise, and specific ultra high performance liquid chromatographic (u-HPLC) method was developed for the analysis of capsaicin in foods. The method validation parameters yielded good results, including linearity, precision, accuracy, and recovery. The u-HPLC separation was performed on a reversed column C18(particle size 2 μm, i.d. 2 mm, length 50 mm, followed by fluorescence detection-excitation 280 nm, emission 325nm). The recovery of capsaicin in gochujang was more than 91%, and the detection limit and lower determination limit of u-HPLC analysis were 0.054 and 0.163 μg/mL for capsaicin and 0.053 and 0.160 μg/mL for dihydrocapsaicin,respectively. The calibration graph for capsaicin and dihydrocapsaicin was linear from 0.2 to 10.0 μg/mL for u-HPLC analysis. The inter-day and intra-day precisions (relative standard deviations) were <5.21% for capsaicin and <9.79% for dihydrocapsaicin while the average recoveries obtained were quantitative 91.1-94.8% for capsaicin, 91.4-97.0% for dihydrocapsacin, indicating good accuracy of the u-HPLC method.

The Effects of Study Abroad Experience and the Length of Stay on Study Practices and Affective Aspects of Language Learning

( Jaeho Choi ) 글로벌영어교육학회(구 호남영어교육학회) 2019 Studies in English education Vol.24 No.1

Study abroad (SA) research has evidenced the effects of SA in expediting second language acquisition. However, the effects of SA have been discussed mostly in terms of linguistic knowledge, lacking attention on affective aspects of language learning and the types of SA programs. This study examined the effects of SA experience on learners’ motivation and affectivity, the types of learning materials, and study hours between different types of SA experience groups. In total, 167 college students majoring in English education participated in the study and completed a survey. The analysis of survey data yielded evidence of the effects of SA experience on affective aspects: anxiety, competence, and motivation. The types of SA experience, which were classified depending on the length of stay, did not have significant effects except on competence. The results imply that SA experience influences affective aspects of language learning regardless of the length of stay. The findings were presented with discussion and suggestions for the future studies.

Rapid Method for Determination of β-Carotene in Foods Using Ultra High Performance Liquid Chromatography

Jaeho Ha,You-Shin Shim,Hye-Young Seo,Hyun-Jin Nam,Masahito Ito,Hiroaki Nakagawa 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.5

The ultra high performance liquid chromatography (u-HPLC) method for determination of β-carotene in foods was validated in terms of precision, accuracy, and linearity. The u-HPLC separation was performed on a reversed column C18 (particle size 2 μm, i.d. 2 mm, length 50 mm),followed by ultra violet (UV) detection at 450 nm. The recovery of β-carotene was more than 84.4% and the limit of detection and limit of quantitation of u-HPLC analysis were 0.28 and 0.85 μg/mL for β-carotene with butylated hydroxytoluene (BHT) and 0.62 and 1.89 μg/mL for β-carotene without BHT, respectively. The calibration graph for β-carotene was linear from 0.1 to 25.0 μg/mL for u-HPLC. The intra- and interday precisions (relative standard deviations) were <7.5 and <7.8%, respectively. Benefits of u-HPLC analysis of β-carotene in foods is reduction of the analysis time to approximately 1/4, saving the volume of solvent to approximately 1/15. It seems that u-HPLC can offer significant improvements in speed, sensitivity, and resolution compared with conventional HPLC, this bodes well for future applications.
