This study investigates the relationship between lexical sophistication features and English proficiency for Korean college students. Essays from the ICNALE(International Corpus Network of Asian Learners of English) corpus were analyzed, using TAALES program. In order to examine whether or not there are statistically significant differences in lexical sophistication features across three groups, MANOVA was conducted. Results showed that the lexical sophistication features were significantly affected by English proficiency level. Essays written by Korean students with different English proficiency levels can be differentiated in terms of various lexical sophistication features including content words frequency, content words familiarity, lexical decision mean reaction time function words, hypernymy verbs, word naming response time function words, age of acquisition content words.

This study is centered on the application of metaphor theory to math education from the cognitive-linguistic view. This study, at first, introduced what metaphor is, and looked into it from the math-educational view. Furthermore, on the basis of that, this study examined the significance of metaphor to math education, and dealt with its relevance to math education, focusing on the functions that metaphor has. This study says that metaphor has the function of explanation, elaboration and representation. In addition, this study examplifies that using metaphor can be an effective math learning strategy for mathematical concept explanation, mathematical connection and mathematical representation learning.

This study explored the lexical sophistication features to distinguish the group membership of English proficiency, using the automatic analysis program of lexical sophistication. A total of 600 essays written by 300 Korean college students were extracted from the ICNALE (International Corpus Network of Asian Learners of English) corpus and a discriminant function analysis was performed using SPSS program. Results showed that the lexical features to distinguish three groups of English proficiency are SUBTLEXUS frequency content words, age of acquisition content words, lexical decision mean reaction time function words, and hypernymy verbs. High-level Korean students used frequent content words from SUBTLEXUS corpus to a lesser degree and produced more sophisticated words that can be learned at a later age and take longer reaction time in lexical decision task, and more concrete verbs.

Despite the fact that South Korea, one of peninsula countries, has been already a middle power in an international arena, it still tends to get stuck in continental-driven inertia and be reluctant to become a consolidated maritime power. In its efforts to deal with the parable of South Korea, designing a tailored-made strategy needs to be initiated in detail. Its design is centered around two variables: classification of waters and prestige. First of all, the domain of waters confronted to South Korea ranges from the greatest threat to scattered national interest. Second, South Korea is prestigiously regarded as the middle power which is equipped with the capability to see beyond its sovereign waters. The Maritime Access Strategy(MAS) can be more clearly explained by three-axis factors: ends, ways, and means. Ends need to be oriented to achieving three types of classified objectives-Deterrence, Engagement around the world to maximize remotely-scattered interest and Check of neighboring countries' seapower expansion, called DEC. Ways is mainly driven by the closer access to three different types of waters: waters of security, check, and interest. The active access and closer approach to the domain of waters need to be maintained with a high degree of willingness and capability. Means is attainable by guiding naval forces to be armed with multiple platforms and functionally-balanced assets. These platforms and assets will allow the naval forces to attain and maintain cost effective means, leading to making MAS feasible. This strategy allows the middle-power Korea to make the best of its maritime assets at various seas, contributing to international stability as well as national security and interest.

Acceleration time history used in the seismic analysis of nuclear power plant structures should envelop a target power spectral density (PSD) function in addition to the design response spectrum in order to have sufficient energy at each frequency for the purpose of ensuring adequate load. The safety for complex long-span highway bridges cannot be over-emphasize. An alternative method to improve the seismic capacity is to ensure the minimum PSD function of the applied seismic load. This study proposes a technical scheme to obtain the reference power spectral density function by using artificial earthquakes which are compatible with the highway bridge design spectrum.

This paper implemented system that run Canonical XML and SOAP messages algorithm. So, can change to more elaborate regular document. Thus, interoperable with other application that takes W3C recommendation. Also, use in several system that physical identify is required when it exchange XML and SOAP messages for web service interoperability. Moreover, Adding the transformation ability between universal encoding scheme and EUC-KR that is internal encoding scheme should be Canonical XML and SOAP messages algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

This study aims to design a framework for analyzing group argumentation in terms of participants' interaction. Regarding the current group argumentation setting as argumentation on socio-scientific issues within participants who have had limited experience on group argumentation, the analytical framework was designed to explain (1) what was each participant's role on group argumentation, (2) how these roles were changed within each time of argumentation, and (3) how the patterns of interaction were changed through seven times of a series of argumentation on socio-scientific issues. Based on the literature review on analytical framework of argumentation in science education including the works on the structure of argumentation, the discourse formation through interaction, and the linguistic approach on participants' interaction, the current research framework was built. Showing the results of applying the designed framework on group argumentation as an example, strength of using the current designed framework was discussed.

최근 섬유제품의 소비패턴이 고급화, 다양화, 개성화됨에 따라 이에 부응한 고기능성과 감성을 지닌 제품의 생산이 요구되고 있다. 이러한 요구에 따라 날염은 유행의 변화에 신속하게 대응하고 다양한 색상과 디자인의 변화를 부여함으로써 각광을 받으며 발전하여 왔다. 그러나 소비자의 요구는 화려한 색상과 정교한 디자인을 요구하고 있으며 점차 환경규제가 높아지고 있으므로 여기에 대응한 날염기술의 발전이 시급한 실정이다. 전사날염기술은 이러한 요구를 만족시킬수 있다는 점에서 관심의 대상이 되어 폭발적인 인기를 누리며 발전하여 왔다. 또한 전사날염은 衣料用 섬유소재 뿐 아니라 카페트, 인테리어 제품과 다른 소재에의 적용으로 확대되어지고 있다. 그러나 열전사날염은 천연섬유에 적용하기 어려운 문제점도 있다. 이 글에서는 전사날염의 개요를 알아보고 천연섬유및 그 혼방품에 대한 실용화를 위한 시도방법과 섬유제품이외의 소재에 대한 응용방법에 대하여 알아보고자 한다.

본 연구에서는 LIP에 의한 극한강우로부터 발생되는 극한홍수량을 산정한다. Huff 형 강우시간 분포를 기후변화 시나리오별로 적용하고, 원전주변지역에서의 상세한 토지이용조건의 변화를 고려하여 빈도별 홍수량을 산정한다. 외부침수해석의 정교화를 위한 상세 지형자료를 구축하고, 원자력발전소 부지의 상세 DEM 자료를 생성한다. 이를 위해서 원자력발전소 부지에서 건물, 연석, 도로 등의 영향을 분석하고 토지이용상황에 따른 조도계수를 산정한다. 또한 원전지역에서의 외부침수재해도 분석을 위해서 국립해양조사원에서 검토한 기후변화를 고려한 조위분석 자료를 외부경계조건으로 설정한 후 부지에 대한 2차원 수리분석을 실시한다. 침수심, 침수유속, 침수시간, 침수동압력 분석 등 2차원 침수해석결과를 바탕으로 발생빈도별 침수심, 침수강도 등의 정량적인 분석을 통해서 빈도별 재해도 곡선을 개발한다. 그리고 원전지역에서의 외부 침수에 대한 대표적인 재해도 곡선을 산정하기 위하여 재현기간별 지속시간에 따른 침수심을 분석하고 정리한다. 재현기간별 침수심에 대해 확률 분포형을 적용하기 위해서 AIC검증을 통한 분포형의 적합성을 분석을 실시한다. 또한 재현기간별 지속시간에 따른 침수심들 간의 상관관계를 분석하여 분포형에 적용한다. 적용된 분포형을 몬테칼로 시뮬레이션을 통한 대표적인 확률론적 외부 침수 재해도 곡선을 산정한다. 본 연구를 바탕으로 원전 부지 및 그 부속 시설물(SSC)의 홍수방지 기능과 홍수 대비 시설물에 대한 적용 절차의 신뢰성, 홍수 저감 및 대응 전략에 대한 정량화가 가능하여 원전 홍수 위험에 대한 정량적인 평가 지원이 가능하겠다. 고려할 외부 홍수와 관련된 원전 내부시설 및 장비에 대한 상세한 모델링 절차, 특정 시나리오에 대한 홍수 방지 및 예방과 관련한 SSC의 정량화, 홍수저감 활동과 관련된 통제실 외부 시설물에 대한 수동 조작에 대한 평가가 이루어질 수 있겠다.
