The prototypical characteristics of the passive construction are following; i) the subject is a direct object in the corresponding active, ii) the subject of the active is indicated by an agentive adjunct or is deleted, and iii) the verb is marked passive (Siewierska 1984). Korean passive markers have not only passive function but also other functions such as potential, spontaneous, and causative. However, in many Korean textbooks, these polysemous functions are presented in mixed types making second language learners confused. To find effective teaching method alternatives to these matters, this study investigated acquisition of the polysemous functions of Korean passive markers. As a result of experimental tasks, second language learners of Korean acquired the passive and the spontaneous in similar patterns. However accuracies of the potential and the causative were significantly different from those of the passive. These result can be interpreted that learners recognized the difference of the passive and the potential and they acquired the potential more slowly than the passive. So teachers must recognize the polysemous characteristics of Korean passive markers. And it is suggested that learners distinguish the passive and the potential using the syntactic structures and contexts rather than the morphological specificities.(Hankuk University of Foreign Studies)

한국어 교사와 중국인 학습자의 신념 차이 해소를 위한 수업 튜닝

정해권 ( Jeong Haegwon ) 이중언어학회 2019 이중언어학 Vol.75 No.-

Adult language learners have strong beliefs or opinions regarding to language learning that based on their previous experiences or assumptions which methods are the best to learn a language. These beliefs could cause anxiety about language teaching in the classroom and disturb their language learning. In this study, the beliefs about language learning of the Korean teachers and Chinese students are investigated and analyzed to find out the differences and to reduce them by classroom tuning for the efficient teaching and learning. Teachers believe that Korean is difficult to learn, and they do not sure of students’ abilities. And students believe learning grammar rules significantly than teachers, so this kind of inconsistence may cause tension in communicative classrooms. They also showed more instrumental motivations than integrative motivations. And both groups believe that language acquisition is linear and structural process and ignore the creativeness of learners. These results showed much lack of knowledge on second language acquisition. For classroom tuning, teachers have to be trained by knowledge on language acquisition, and learners must be realized improper learning methods by guidance of teachers.

A two-dimensional circular cylinder freely falling in a channel has been simulated by using immersed boundary ? lattice Boltzmann method (IB-LBM) in order to analyze the characteristics of motion originated by the interaction between the fluid flow and the cylinder. The wide range of the solid/fluid density ratio has been considered to identify the effect of the solid/fluid density ratio on the motion characteristics such as the falling time, the transverse force and the trajectory in the streamwise and transverse directions. In addition, the effect of the gap between the cylinder and the wall on the motion of a two-dimensional freely falling circular cylinder has been revealed by taking into account a various range of the gap size. As the cylinder is close to the wall at the initial dropping position, vortex shedding in the wake occurs early since the shear flow formed in the spacing between the cylinder and the wall drives flow instabilities from the initial stage of freely falling. In order to consider the characteristics of transverse motion of the cylinder in the initial stage of freely falling, quantitative information about the cylinder motion variables such as the transverse force, trajectory and settling time has been investigate.

Many learners and teachers felt difficult to learn and teach the structure of Korean particle (n)un and i/ka. In this article, we assume that the meanings of (n)un are ``topic`` and ``contrast``, and the meanings of i/ka are ``focus`` and ``neutral``. The meanings of these particles have different syntactic structures and phonological prominences. However, the contrastive (n)un and the focal i/ka have similar structures in Korean language. Four different proficiency groups of learners of Korean as a Second Language were enrolled in a multiple choice cloze test and an acceptability judgement test. These tests were designed to examine systematic development of learner languages in the acquisition of i/ka and (n)un. The results showed that the developmental sequences of Korean particles i/ka and (n)un were the neutral i/ka, the focal i/ka, topical (n)un, and contrastive (n)un in this order. Because of the structural similarities, contrastive (n)un and the focal i/ka were hard to be acquired by the learners. According to these results, the study suggests that the Korean language teaching can be more effective if the teaching method followed these developmental patterns of the learners.

It is difficult to find the accurate meanings of grammatical modalities because they express speaker’s subjective assessment of the status of the proposition and have various ranges of scale. Based on the onomasiological approach, it can identify the concepts of deontic modality and finds obligative markers for each language. And the meaning of each marker is defined not by the sense of dictionary or transliteration, but by the denotation of examplars in the situations of context. In this study, the probabilistic semantic map using parallel translation text is used to compare the ranges of meaning and subtle difference of each obligative marker. The English must represents strong obligation by the speaker’s authority, less strong obligation, and epistemic meaning. Korean -eya ha- and Russian dolzen mainly represents strong obligation and less strong obligation. Mandarin Chinese bixu, however, represents less strong and neutral obligations. This probabilistic semantic map enables us to grasp subtle differences in meaning between grammatical elements, which can be useful for grammar descriptions, foreign language education, and translation.

최근 에너지 효율이 높은 공정기술의 수요가 증가하면서 분리막을 이용한 기체분리가 많은 연구자들의 관심을 모으고 있다. 현재 분리막에 의한 기체 분리 시장은 고분자막이 독점하고 있으며 탄화수소와 같은 응축기체 분리시장이 휠씬 큼에도 불구하고 주로 비응축 기체분리에 제한되고 있다. 이는 고분자 재료의 물성에 한계가 있기 때문이다. 제올라이트막이나 제올라이트/고분자 복합막이 제올라이트의 우수한 분리력과 화학적/열적 특성으로 인해 고분자막의 한계를 극복할 수 있는 대안이 될 수 있다. 이번 총설에서는 이러한 기체분리를 위한 제올라이트막과 제올라이트/고분자 복합막에 대해 간략히 소개하고자 한다. Recently membrane-based gas separation has attracted a great deal of research interests due to the growing demands on greener technologies. Current membrane-based gas separation is dominant by polymer membranes and limited mostly to non-condensable gases even though condensable gases such hydrocarbon isomers are much more attractive. This is primarily due to the limitations of polymer materials. Zeolites and their composites with polymer can offer alternative to current polymeric membranes owing to their superior separation and chemical/thermal properties. This review is intended to provide a brief overview on zeolite and zeolite/polymer composite membranes for gas separation applications.

한국어 감정 구문의 문법 표상과 개념적 사상

In Korean, the psychological situation where an experiencer is affected by stimulus is also expressed in a transitive construction, and the emotional situation, which is a subcategory of psychological situations, is expressed with the multiple nominative construction as well. Psychological situations indicate low transitivity because of ambiguous affectedness between participants (Hopper and Thompson 1980), and share the properties of low degree of elaboration of situation like the middle voice (Kemmer 1993). In the alignment system related with case marking, many languages have a split intransitive according to activity of verbs. In Korean, the second argument of the transitive construction is marked the same as the first argument in such cases. In expressing emotions, the two arguments are represented in the multiple nominative construction through the conceptual blending, where the stimulus is internalized as a mental reality to the experiencer.

한국어 수사구의 언어유형론적 고찰

정해권 ( Jeong Haegwon ) 대한언어학회 2017 언어학 Vol.25 No.1

In a linguistic typological perspective, Korean has fluently developed classifiers which represent limits of abstracting the objects and an early stage of categorizing them. Therefore, it appears that the numeral phrases with repeaters or classifiers are older than the forms without a classifier. Old Korean poems first represent the number and noun interpreted as a form of the number and repeater construction. On the other hand, the basic number of Korean did not appear at the same time but developed sequentially. Number five and others in many languages have the etymological association with `hands`, but Korean numbers are probably not. The Korean number system uses the reconstructed number ten un as a base. In addition, the variation of number twenty and forty may be traces of the vigesimal numeral system.
