「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.

2015 교육과정 초등 국어과 교과서 학습 목표 분석 - 신 교육목표분류학을 적용하여 -

이재호 ( Lee¸ Jae-ho ),박기범 ( Park¸ Kibeom ) 한국초등국어교육학회 2021 한국초등국어교육 Vol.71 No.-

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.

A Study on User Interface Design According to 3D Menu Type and Control Type for 3D Displays

Jaeho Kim,Sungwook Jung,Jaeho Choe,Eui S. Jung 대한인간공학회 2011 大韓人間工學會誌 Vol.30 No.4

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.

Effects of Diagonal Pattern Self-Exercise on Trunk Control, Balance, and Gait Ability in Chronic Stroke Patients

Jaeho Yang,Shinjun Park,Soonhee Kim 국제물리치료연구학회 2020 Journal of International Academy of Physical Ther Vol.11 No.2

Background: Weakness of the trunk muscles decreases the trunk control ability of stroke patients, which is significantly related to balance and gait. Objectives: To compare the impact of diagonal pattern self-exercise on an unstable surface and a stable surface for trunk rehabilitation on trunk control, balance, and gait ability in stroke patients. Design: Nonequivalent control group design. Methods: Twenty four participants were randomized into the experimental group (diagonal pattern self-exercise while sitting on an unstable surface, n=12) and the control group (diagonal pattern self-exercise while sitting on a stable surface, n=12). All interventions were conducted for 30 minutes, three times a week for four weeks, and the trunk impairment scale (TIS), berg balance scale (BBS), functional gait assessment (FGA), and G-walk were measured. Results: All groups indicated significant increases in all variables (TIS, BBS, FGA, cadence, speed, stride length) after four weeks. The TIS, BBS, FGA, cadence, gait speed, and stride length group-by-time were significantly different between the two groups. Conclusion: We found that, in stroke patients, diagonal pattern self-exercise on an unstable surface is a more effective method for improving trunk control, balance, and gait ability than diagonal pattern self-exercise on a stable surface.

70 Years after WW2: The Dynamics of the Northeast Asian Security Environment : The Rise of a New Regional Order and South Korea`s Deepening Strategic Dilemma

( Jaeho Hwang ) 한국국방연구원 2015 The Korean Journal of Defense Analysis Vol.27 No.2

The year 2015 has many implications for South Korea. It marks the 70th anniversary of the end of World War II in 1945, the subsequent independence of the Korean Peninsula from the rule of Imperial Japan, and the division of the Peninsula into two Koreas based on two different ideologies and political systems. South Korea, based on liberal democracy, has renovated itself and emerged as a middle power with diplomatic and economic strength. However, the unhappy legacy of 1945 still haunts today’s ROK despite its growth, both in quantity and quality. The U.S.-led regional order in the post-War period is experiencing a massive upheaval, as the United States seeks to maintain the status quo by using Japan, and China intends to shape a new regional order. Against this backdrop, South Korea is being demanded to choose a position. In order to deal with this situation, Seoul should put its national interest as its top priority, while taking into account which option serves better for regional peace and prosperity.
