통역을 통한 한국어 말하기 교육의 가능성 탐색 연구 - 중국인 학습자를 중심으로 -
Zhang Chuanwei,LI ZHENGSHI 국어교과교육학회 2017 국어교과교육연구 Vol.30 No.-
본고는 통역과 말하기의 상관관계를 살펴보고 한국어 교육에서 통역을 활용하여 중국인 한국어 학습자의 말하기 능력을 향상시키는 방안을 모색 하는 데 그 목적이 있다. 이를 위해 통역과 말하기의 과정, 통역의 의사소 통 원리, 통역 교육은 말하기 능력에 미치는 영향을 살펴보고 중국내 한국 어 통역 교육의 현황을 감안하여 한국어 말하기 교육에서 통역을 활용하는 방안을 제시하고자 한다. 기존의 연구에 따르면 통역은 학습자의 통합적인 외국어 능력을 요구하 며 모국어 지식과 다양한 훈련방법을 통해 학습자의 외국어 능력, 특히 말 하기 능력을 높일 수 있다. 여태까지 통역을 외국어 교육의 한 분야로 여기 는 연구들이 많다. 하지만 본고에서는 한국어교육의 한 분야로서의 통역이 아니라 교육 도구로서의 통역은 중국인 학습자의 말하기 능력을 향상시키 기 위해 한국어 교육에서 어떤 역할을 하고 있는지, 어떻게 활용해야 할지 에 대해 연구하고자 한다. 마지막으로 본고에서 통역과 관련된 이론과 교육 방법을 바탕으로 통역을 통한 한국어 말하기 교육의 수업 모형과 수업 방 안을 제시하도록 한다. The aim of this study is to examine the correlation between interpretation and speaking, and seek a program that can improve Korean speaking abilities for Chinese Korean leaners through interpretation. Firstly, the author will try to examine the process of speaking and interpretation, the principles of interpretation, and how interpretation effects speaking abilities. Then based on the discussion of prior study, the author will try to present a educational program and educational contents through interpretation for Korean language learners in China. As we all know, interpretation education is indispensable in foreign language education. Interpretation education requests combined foreign language abilities of the leaners. And some research suggest that interpretation training methods can help to improve the foreign language abilities of the learners, especially speaking abilities. Thus far , most of the study regard interpretation as a part of the foreign language education. But in this paper, the author will discuss the interpretation as education tool in Korean education, and how the interpretation play roles in Korean education. In the end, the author will try to put forward how to apply interpretation in Korean speaking education.

Effect of Interstitial Solutes on Precipitation Behavior of 9-12% Chromium Ferritic Steels
Xingang Tao,Chuanwei Li,Lizhan Han,Jianfeng Gu 대한금속·재료학회 2015 METALS AND MATERIALS International Vol.21 No.3
Effects of nitrogen and carbon content on precipitation behavior in two 9-12% Cr ferritic heat-resistant steels during isothermal transformation were investigated. Isothermal aging treatments at 700 °C after solution annealing were carried out for the different periods up to over 220 h. Microstructure characterization was performed by many characterization methods, such as physicochemical phase analysis, X-ray diffraction and scanning electron microscope etc. It was found that Cr-rich M2N nitride was formed as the main precipitate in the alloy A with content of 0.15% N and 0.03% C in wt%, together with some Cr-rich M23C6 carbide and Nb-rich MN nitride. Comparatively, the aged alloy B with 0.05% N and 0.11% C, predominantly contains Cr-rich M23C6 carbides. Besides, both alloys showed the similar microstructure evolution process: The precipitates were found to be formed initially along prior austenite grain boundaries, then grew toward interior of grain in the form of cell with the increasing aging time. Meanwhile, the cell growth feature was also discussed based on the experimental observation in well-controlled specimens.

Dilatometry is a useful technique to obtain experimental data concerning transformation. In this paper, a dilation conversionalmodel was established to calculate carbides fraction in AISI H13 hot-work tool steel based on the measured length changes. After carbides precipitation, the alloy contents in the matrix changed. In the usual models, the content of carbon atoms afterprecipitation is considered as the only element that affects the lattice constant and the content of the alloy elements suchas Cr, Mo, Mn, V are often ignored. In the model introduced in this paper, the alloying elements (Cr, Mo, Mn, V) changescaused by carbides precipitation are incorporated. The carbides were identified using scanning electron microscope andtransmission electron microscope. The relationship between lattice constant of carbides and temperature are measured byhigh-temperature X-ray diffraction. The results indicate that the carbides observed in all specimens cooled at different ratesare V-rich MC and Cr-rich M23C6,and most of them are V-rich MC, only very few are Cr-rich M23C6. The model includingthe effects of substitutional alloying elements shows a good improvement on carbides fraction predictions. In addition, lowercooling rate advances the carbides precipitation for AISI H13 specimens. The results between experiments and mathematicalmodel agree well.
