In recent years there has been much discussion about whether there is a critical, or sensitive period for language acquisition. Research on a critical period provides an excellent example around which we can organize a discussion of the behavioral and neural evidence. In this paper, the early history of critical periods and evidence for the existence of critical periods in various domains of human cognition and learning are reviewed. Followed by this overview, evidence for a critical period in both linguistic and non linguistic area are presented. The paper then provides some unresolved questions regarding a critical period in language acquisition and states what the outcome of this issues mean for an understanding of language acquisition. Finally the paper concludes with some educational implications of a critical period for practice.

Recently, researches into ways of improving large vocabulary continuous speech recognition and speech synthesis are being carried out intensively as the field of speech information technology is progressing rapidly. In the field of speech recognition, developments of stochastic methods such as HMM require large amount of speech data for training, and also in the field of speech synthesis, recent practices show that synthesis of better quality can be produced by selecting and connecting only the variable size of speech data from the large amount of speech data. In this paper we design and discuss linguistic contents for speech copora for speech recognition and synthesis to be shared in common.

The purpose of this study was to examine 30 logical connectors in the essay writing of Korean university students for comparison with the use in similar types of native English writing. The main questions addressed were as follows: Do Korean EFL students tend to over- or underuse logical connectors? What types of connectors differentiate Korean learners from native use? To answer these questions, EFL learner data were compared with data from native speakers using computerized corpora and linguistic software tools to speed up the initial stage of the linguistic analysis. The analysis revealed that Korean EFL learners tend to overuse logical connectors in the initial position of the sentence, and that they tend to overuse additive connectors such as 'moreover', 'besides', and 'furthermore', whereas they underuse contrastive connectors such as 'yet' and 'instead'. On the basis of the results of this study, some pedagogical implications are made concerning the need for teaching of the semantic, stylistic, and syntactic behavior of logical connectors.

Listening comprehension is an integrative and creative process of interaction through which listeners receive speakers' production of linguistic or non-linguistic knowledge. Compared with reading comprehension, it may arouse difficulties and thus impose more burdens on foreign learners. The Audio-Lingual Method focused primarily on speaking. Mimicry, repetition, rote memory, and transformation drills actually interfered with listening comprehension. So learners lost interest and were not highly motivated. Improving listening comprehension requires continual attentiveness and interest. Listening skill can be extended systematically only when students are frequently exposed to a wide range of listening materials with an affective, cultural, social, and psycholinguistic approach. Therefore, teachers should help students learn how to comprehend intactly the overall meaning of intended messages. The literature on teaching listening skill suggests various useful activities: TPR, dictation, role playing, singing, picture recognition, completion, prediction, seeking specific information, summarizing, labeling, humor, jokes, cartoons, media, and so on. Practical classroom teaching necessitates a systematic procedure in which students should take part in meaningful tasks/activities. In addition to this, learners must practice listening comprehension trough a self-study process.

This paper presents a systematic approach to identify a linguistic fuzzy model for a multi-input and single-output complex system. Such a model is composed of fuzzy rules, and its output is inferred by the simplified reasoning. The structure and membership function parameters for a fuzzy model are automatically and simultaneously identified by GA (Genetic Algorithm). After GA search, optimal parameters for the fuzzy model are finely tuned by a gradient method. A numerical example is provided to evaluate the feasibility of the proposed approach. Comparison shows that the suggested approach can produce the linguistic fuzzy model with higher accuracy and a smaller number of rules than the ones achieved previously in other methods.

This paper aims to offer a solution based on intelligent document classification to create a user-centric information retrieval system allowing user-centric linguistic expression. So, structures expressing user intention and fine document classifying process using EBL, similarity, knowledge base, user intention, are proposed. To overcome the problem requiring huge and exact semantic information, a hybrid process is designed integrating keyword, thesaurus, probability and user intention information. User intention tree hierarchy is build and a method of extracting group intention between key words and user intentions is proposed. These structures and processes are implemented in HDCI(Hybrid Document Classification with Intention) system. HDCI consists of analyzing user intention and classifying web documents stages. Classifying stage is composed of knowledge base process, similarity process and hybrid coordinating process. With the help of user intention related structures and hybrid coordinating process, HDCI can efficiently categorize web documents in according to user's complex linguistic expression with small priori information.

There is great confusion over what constitutes public diplomacy (PD), who its actors are, and the relevance of non-state actors. In the Korean context, in addition to the general fuzziness of the concept, linguistic peculiarities of the terms gonggong and gongjung both of which refer to public, waegyo, which is interchangeably used for international affairs, foreign policy and diplomacy, and juche which is simultaneously used for actor and agent, add more layers of confusion. While the term PD in Korea is based almost entirely on Western conceptualization, these linguistic peculiarities prevent fruitful conversations among scholars and practitioners on PD. Against this background, this research note explores and addresses conceptual ambiguities that pertains to PD and the policy discourse on the topic, particularly on non-state PD in Korea. The paper draws on Korean government's PD-related policy documents and Diplomatic White Papers and all relevant academic articles found in Korean-language journals registered in the Korean Citation Index (KCI), which are analysed to gain an understanding of the PD-related policy discourse in Korea.

Crowdfunding has seen an enormous rise, becoming a new alternative funding source for emerging startup companies in recent years. Despite the huge success of crowdfunding, it has been reported that only around 40% of crowdfunding campaigns successfully raise the desired goal amount. The purpose of this study is to investigate key factors influencing successful fundraising on crowdfunding platforms. To this end, we mainly focus on contents of project campaigns, particularly their linguistic cues as well as multiple features extracted from project information and multimedia contents. We reveal which of these features are useful for predicting success of crowdfunding campaigns, and then build a predictive model based on those selected features. Our experimental results demonstrate that the built model predicts the success or failure of a crowdfunding campaign with 86.15% accuracy.

The purpose of this research was to study the origins and the meanings of the Kokal (고깔). Comparative linguistic analytical approaches were employed to trace the development of the word, the Kokal(고깔). Results of this study revealed that the kotkal(곳갈, 곧갈) was a general term referring to a variety of head coverings in eh period of Choson Dynasty. This broad meanings of the Kotkal(곳갈,곧갈) of the Chosun Dynasty period has been changed to a narrow sense meanings a conical cap made of folds of the material, mainly used by some of the Buddhist monks in modern Korean. Also, the phonetic value of the Kotkal(곳갈,곧갈) of the Choson Dynasty period changed to the Kokal(고깔) in modern Korean. A variety of words for the Kokal(고깔) was found in the different languages such as Latin, English, French, Turkish, German, Mongolian, and Chinese. The examination and analysis of this study indicated that the origin of the Korean word Kotkal(곳갈,곧갈) or Kokal(고깔) and the meanings of it were derived from LL. Cuculla(monk's cowl)

In this paper, we have proposed Auto-TUS, an automatic transcription module of three union symbols-hyphen, dash and tilde (‘­’, ‘―’, ‘∼’)-using their linguistic contexts. Few previous studies have discussed the problems of ambiguities in transcribing symbols into Korean alphabetic letters. We have classified six different reading formulae of the union symbols, analyzed the left and right contexts of the symbols, and investigated selection rules and distributions between the symbols and their contexts. Based on these linguistic features, 86 stereotyped patterns, 78 rules and 8 heuristics determining the types of reading formulae are suggested for Auto-TUS. This module works modularly in three steps. The pilot test was conducted with three test suites, which contains respectively 418, 987 and 1,014 clusters of words containing a union symbol. Encouraging results of 97.36%, 98.48%, 96.55% accuracy were obtained for three test suites. Our next phases are to develop a guessing routine for unknown contexts of the union symbols by using statistical information; to refine the proper nouns and terminology detecting module; and to apply Auto-TUS on a larger scale.
