This study examined variability of gestures and their correlation with vocabulary acquisition in the communication of infants. Subjects were 96 infants, 7 to 24 months of age, residing in Seoul and its vicinity. Instruments were the Communication and Symbolic Behavior Scales (Iverson, et al., 1999) and the MacAuther Communicative Development Inventory-Korean (Bae and Lim, 2002). Data were analyzed by one-way ANOVA and Pearson's Correlation. Results identified monthly changes in types of communicative gesture used by infants: more deictic at younger and more representational at older ages. Deictic gestures were related to size of the receptive vocabulary and size of the whole vocabulary. Representational gestures were related to acquisition of expressive vocabulary, size of the receptive, and size of the whole vocabulary.

The purpose of this study was to identify the effect of gesture and facial expression on persona effects. Fifty-six college students were recruited for this study, and non-verbal communication skills were applied to a pedagogical agent with gesture (conversational vs. deictic) and facial expression. The conversational gesture may have relationship with social interaction hypothesis of pedagogical agent while the deictic gesture may have relationship with attentional guidance hypothesis. The facial expression can be assumed to facilitate the social interaction between the pedagogical agent and learners. Interestingly, the conversational gesture group showed a tendency of outperforming the deictic gesture group. It may imply that the social interaction theory has a strong impact on cognitive support as well as social interaction for learners. There was a significant interaction effect on the engagement when both of facial expression and conversational gesture were applied. This result has two implications. First, facial expression can facilitate the persona effect for engagement.

Gestures are a common phenomenon of human communication. There exists little research concerned with the gestures in science education, and most researches of gestures have focused on individual gestures. However, learning occurs through sociocultural interactions with friends, family, teachers, and others in society. Hence, the purpose of this study was to investigate and identify the types and features of gestures which were made by elementary students to communicate with peers in science discourse. A group of six fourth-graders was observed in eight science discourses where they talked about ideas related to thermal concepts. The data was collected through interviews and questionnaires. The analysis of the data showed that students' gestures in science discourses could be classified into seven types: signal iconic gesture, illustrative iconic gesture, personal deictic gesture, object deictic gesture, beat gesture, emotional metaphoric gesture, and content metaphoric gesture. It was also found that these gestures had functions of repeating, supplementing, and replacing utterance to communicate with others. Students frequently expressed scientific terms metaphorically as everyday terms through their gestures. Gestures were shared, imitated, and transferred in the communication process, and students' gestures also made influence on other students' ideas through these processes.

This paper investigates children's comprehension and production of demonstrative pronouns (DPs), 'zhege' (this) and 'nage' (that), in Mandarin Chinese. Subjects are children of ages three, four, five and six. Based on the results of the present experiment, children's developmental stages and the corresponding age grading are provided. Also, the present study incorporates a physical clue into the experiment. The result suggests that in the acquisition of deixis children rely highly on physical context to work out the meaning distinction. In addition, Piaget's egocentrism hypothesis and H. Clark's marking hypothesis are examined in the study. The result seems to support the egocentrism hypothesis. Subjects under the age of six do fail to shift the deictic center when they and the experimenter have a different perspective. As for the marking hypothesis, the study seems to challenge the hypothesis. The result shows that children actually performed better on the marked term 'zhege' than the unmarked member 'nage'.

언어기반 대화 시스템에서는 시스템과 사용자의 대화가 발화 자체만으로 이루어지기 때문에 사용자가 사람과 대화하는 것처럼 지시 대용어를 사용할 수 없어서 불편하다. 그리고 사용자의 발화 의미를 시스템이 정확하게 해석하기가 어렵다. 하지만 이런 언어기반 대화 시스템과는 달리 멀티모달 대화 시스템에서는 발화 자체의 정보뿐만이 아닌 제스처와 같은 발화 이외의 행위 정보들이 포함되는데 이 정보를 이용하면 지시 대용어의 처리가 가능해짐으로 시스템과의 대화가 좀 더 자연스러워진다. 본 논문에서는 군집화와 격틀을 이용하여 여러 사물들 중에서 지시 대용어가 될 가능성이 있는 지시 후보 선정을 한다. 그리고 특출성 점수와 엔트로피를 이용하여 후보 사물들 중에서 지시 대용어가 될 수 있는 대상을 선택하는 알고리즘을 제안한다. 시뮬레이션 환경에서의 실험결과 평균 2.8번의 상호작용으로 지시 대용어를 처리할 수 있었다.

This paper deals with the anaphoric usage of demonstratives when they refer to what are already mentioned in the context. We examine syntactic, semantic and pragmatic factors that contribute to the choice of demonstratives. As for anaphoric usage, English and Spanish show the even distribution between proximal and distal demonstratives with the meaning of their deictic counterparts. Korean and Russian, however, show the uneven distribution of the more prevalent form (unmarked on) and the lesser one (market one). This study aims at a typological explanation for the anaphoric usage of demonstratives through comparison and contrast with such factors as the distance to the antecedent, cognitive status, psychological distance and the center of attention.

Objective: The aim of this study is to make the taxonomy for classifying diverse touchless gestures and establish the design requirements that should be considered in determining suitable gestures during gesture-based interaction design. Background: Recently, the applicability of touchless gestures is more and more increasing as relevant technologies are being advanced. However, before touchless gestures are widely applied to various devices or systems, the understanding on human gestures' natures and their standardization should be prerequisite. Method: In this study, diverse gesture types in various literatures were collected and, based on those, a new taxonomy for classifying touchless gestures was proposed. And many gesture-based interaction design cases and studies were analyzed. Results: The proposed taxonomy consisted of two dimensions: shape (deictic, manipulative, semantic, or descriptive) and motion(static or dynamic). The case analysis based on the taxonomy showed that manipulative and dynamic gestures were widely applied. Conclusion: Four core requirements for valuable touchless gestures were intuitiveness, learnability, convenience and discriminability. Application: The gesture taxonomy can be applied to produce alternatives of applicable touchless gestures, and four design requirements can be used as the criteria for evaluating the alternatives.

본 연구는 실어증 환자를 대상으로 화시적(deictic)인 대명사와 조응적(anaphoric)인 대명사의 처리를 살펴보기 위하여 실시되었다. 인칭 대명사와 지시대명사는 기능적인 측면에서 각각 화시적인 대명사와 조응적인 대명사로 구분될 수 있다. 화시적인 대명사란 발화상황에서 직접 가리킬 수 있는 대명사를 지칭하며 언어적 표현에 의존하기보다는 상황 의존적 대명사를 말하고 조응적인 대명사란 앞선 문맥에서 제시된 언어표현을 선행사로 되받는 대명사를 말한다. 인칭 대명사 가운데 1인칭('나')과 2인칭('너')은 화시적인 대명사로, 3인칭 '그'는 조응적인 대명사로, 3인칭 재귀대명사 '자기'는 화시와 조응의 혼합된 것으로 보았다. 지시 대명사의 경우 '이-/저-'는 화시적인 용법이 지배적인 것으로 분류하였고, '그-'는 조응의 '그-'와 화시의 '그-'l로 나누었다. 실험 1은 화시적인 1,2인칭 대명사 처리를 알아보기 위해서 실시되었다. 실험 1의 결과 3명의 브로카 환자와 qdua의 실명증 환자는 1,2인칭 대명사를 비교적 잘 처리하였다. 실험 2는 인칭대명사 가운데 화시적인 요소와 조응적 요소를 모두 가지고 있는 3인칭 재귀대명사 '자기'와 조응적 성격의 3인칭 대명사 '그'의 처리를 알아보기 위하여 실시되었다. 실험 2의 결과 3인칭 재귀사 '자기'의 경우 실험 1보다는 처리에 어려움을 보였으나 3인칭 대명사 '그'보다는 잘 처리하는 결과를 보였다. 실험 3은 지시 대명사 관련 실험으로서 화시적 용법의 '이-/그-/저-'와 조응적 용법의 '그-'의 처리를 살펴보기 위해 실시되었다. 실험 3의 결과 지시 대명사의 처리에 있어서 화시적 용법의 '이-/그-/저-'는 비교적 잘 처리하였으나 조응적 용법의 '그-'를 처리하는 데에는 어려움을 보였다. 실험 1,2,3에서 실어증 환자들은 화시적 대명사를 조응적 대명사보다 더 잘 처리하는 동일한 결과를 보였다. 이러한 실험 결과들은 실어증 환자들이 뇌손상으로 인해 문법적 언어처리에는 어려움을 보이지만 비언어적인, 세상 지식과 관련된 화시적 대명사의 처리는 가능할 것이라는 가설을 뒷받침 해준다. 또한 이러한 실험 결과를 통해 대명사의 기능적인 측면에서 화시와 조응의 처리가 구분되어 있음을 보여준다.

The paper pragmatically analyzes ellipsis in Russian and Polish colloquial and informal texts. The famous Polish writer Sławomir $Mro{\dot{z}}ek^{\prime}s$ "Exit to the South", written in Polish and Russian is used as a material for the analysis. Russian and Polish ellipsis in colloquial and informal texts have in common that the givenness and subjecthood of the elliptical co-referent play a crucial role. However, the ellipsis in two languages also has differences in many ways. Above all, in the Polish texts of colloquial and informal style, a theme is likely to be elliptical and the coreferential relation reaches to an extra-sentential antecedent, while the ellipsis in analysed Russian texts in most cases requires coordinate, subordinate or relative clauses, and the elliptical co-referent tends to have an intra-sentential antecedent. The ellipsis of the theme-subject is unmarked in Polish, where every verbal form has an ending denoting person. Unlike formal style which often allows explicit noun subject, Polish text of colloquial and informal style prefer null form of the subject in most cases. If Polish sentences have explicit theme-subjects, they disambiguate intervening and main themes, and indicate the contrast, the focus, the introduction of new narratives or the change of speaker's point of view. Sometimes direct speeches and deictic pronouns also need explicit theme-subjects in Polish sentences. On the other hand, the ellipsis of the theme-subject is marked in Russian even in colloquial and informal texts. The theme-subject can be deleted in Russian colloquial and informal texts, if the subject is a form of the first or the second person, or if the aspect and the tense of the antecedent sentence's verb are the same as those of the given sentence's verb and both the antecedent and the coreferential word have the nominative case.

N-gram analysis casts a new look at the n-word cluster in use different from the previously known idioms. It analyzes a corpus of English textbooks for frequently occurring n consecutive words mechanically using a concordance software, which is different from the previously known idioms. The current paper aims at extracting and comparing 4-gram words clusters between South Korean high school English textbooks and its North Korean counterpart. The classification criteria includes number of tokens and types between the two across oral and written languages in the textbooks. The criteria also use the grammatical categories and functional categories to classify and compare the 4-gram words clusters. The grammatical categories include noun phrases, verb phrases, prepositional phrases, partial clauses and others. The functional categories include deictic function, text organizers, stance and others. The findings are: South Korean high school English textbook contains more tokens and types in both oral and written languages. Verb phrase and partial clause 4-grams are grammatically most frequently encountered categories across both South and North Korean high school English textbooks. Stance is most dominant functional category in both South and North Korean English textbooks.
