  • The purpose of this corpus-based study was to find 4-word lexical bundles in computer science research articles. As the demand for research articles (RAs) for international publication increases, the need for acquiring field-specific writing conventions for this academic genre has become a burning issue. Particularly, one area of burgeoning interest in the examination of rhetorical structures and linguistic features of RAs is the use of lexical bundles, the indispensable building blocks that make up an academic discourse. To illustrate, different academic discourses rely on distinctive repertoires of lexical bundles. Because lexical bundles are often acquired as a whole, the recurring multi-word sequences can be retrieved automatically to make written discourse more fluent and natural. Therefore, the proper use of rhetorical devices specific to a particular discipline can be a vital indicator of success within the discourse communities. Hence, to identify linguistic features that make up specific registers, this corpus-based study examines the types and usage frequency of lexical bundles in the discipline of CS, one of the most in-demand fields world over. Given that lexical bundles are empirically-derived formulaic multi-word units, identifying core lexical bundles used in RAs, they may provide insights into the specificity of particular CS text types. This will in turn provide empirical evidence of register specificity and technicality within the academic discourse of computer science. As in the results, pedagogical implications and suggestions for future research are discussed.

  • 본 연구는 창의성이 발현되는 인지적 과정이 무엇인지에 대한 관점을 이론적으로 고찰한 후, 이를 토대로 수학적 창의성을 계발하고 측정하는데 바람직한 과제와 수업 방향을 제시하는 것을 목적으로 한다. 먼저, 창의성에 대한 영역-특수적 관점과 영역-일반적 관점을 이론적으로 고찰하였다. 창의성 발현에 대한 이 두 관점은 이론적 논의에 그치지 않고 수학적 창의성을 계발하고 신장시키기 위해 고안된 과제와 프로그램에 영향을 미친다. 창의성에 대한 교육학적 고찰에서는 수학적 창의성을 검사하고 계발하기 위한 과제와 수업 프로그램이 구비해야할 조건을 이론적으로 탐색한 후, 이를 바탕으로 실제 수학 수업에서 활용가능한 과제와 수업 사례를 제시하였다. 이 연구의 핵심적인 결론은 창의성의 발현되는 과정에 대한 연구는 수학적 창의성 연구의 핵심이 되어야 하며, 아울러 확산적 사고는 수학적 창의성 계발을 위한 필요조건이지만 충분조건은 될 수 없으므로, 수학적 창의성을 계발하기 위해서는 일반화, 추상화 등 다양한 수학적 추론과 수학적 지식을 고려할 필요가 있다.

  • This study aims to analyze the types of writing tasks in Korean language and literature majors. There are many foreign students in the department of Korean language and literature. It is important to identify the type of task that is the subject of communication when conducting communication activities in an academic context. In particular, writing tasks are among the most important tasks that learners must perform. This is because most of the tasks assigned within the university curriculum are assigned to writing tasks, and evaluation is often done through learner writing. Therefore, this study investigated the types of tasks to be imposed on Korean Language and Literature majors. As a result, summary is the most frequent type of task in the department of Korean language. And in the department of Korean literature, review is most frequent type of task. The results of this study will help to prepare contents for foreign undergraduates of Korean language and literature majors.

  • Mobile genetic segments, or transposons, are also referred to as jumping genes as they can shift from one position in the genome to another, thus inducing a chromosomal mutation. According to the target site-specificity of the transposon during a transposition event, the result is either the insertion of a gene of interest at a specific chromosomal site, or the creation of knockout mutants. The former situation includes the integration of conjugative transposons via site-specific recombination, several transposons preferring a target site of a conserved AT-rich sequence, and Tn7 being site-specifically inserted at attTn7, the downstream of the essential glmS gene. The latter situation is exploited for random mutagenesis in many prokaryotes, including IS (insertion sequence) elements, mariner, Mu, Tn3 derivatives (Tn4430 and Tn917), Tn5, modified Tn7, Tn10, Tn552, and Ty1, enabling a variety of genetic manipulations. Randomly inserted transposons have been previously employed for a variety of applications such as genetic footprinting, gene transcriptional and translational fusion, signature-tagged mutagenesis (STM), DNA or cDNA sequencing, transposon site hybridization (TraSH), and scanning linker mutagenesis (SLM). Therefore, transposon-mediated genetic engineering is a valuable discipline for the study of bacterial physiology and pathogenesis in living hosts.

  • 정보보호 분야 중 내부자 위협은 미국 카네기멜런대학 부설 연구소를 중심으로 연구가 꾸준히 이어오고 있을 정도로 중요도가 높다. 이에 반해 우리는 별도 연구기관이 없는 실정이며, 특히 국가 생존과 직결되는 국방 IT 환경에 대한 내부자 위협 연구가 보다 깊이 있게 진행되고 있지 않은 것이 현실이다. 그뿐만 아니라 군의 특수성으로 인해 국방 IT 보안은 학문으로서의 연구가 제한되며, 따라서 개념에 대한 정립조차도 제대로 이루어지지 못하고 있다. 뿐만아니라 환경의 차이로 인해 미국의 기준을 그대로 빌릴 수 없기 때문에, 본 논문에서는 국방 IT 환경을 분석한 뒤 한국군 환경에 적합한 내부자(위협)를 정의하고, 내부자 위협 종류 및 완화방안에 대해 제안해 보고자 한다.
