In this paper, the GPC algorithm is developed for ACS(advanced control system). ACS equals to DCS(distributed control system) with some advanced control algorithm, for example, fuzzy logic controller, autotuning. By its embedded structural control language, which uses simple function codes corresponding to each function blocks, it is possible to construct multiloop controller. The developed GPC function code is divided by RLS (recursive least square) parameter estimator and GPC controller. Simulation result show the availability of GPC function code using the control language.

The finger language is the part of the sign language, which is a language system that expresses vowels and consonants with hand gestures. Korean finger language has 31 gestures and each of them needs a lot of learning models for accurate recognition. If there exist mass learning models, it spends a lot of time to search. So a real-time awareness system concentrates on how to reduce search spaces. For solving these problems, this paper suggest a hierarchy HMM structure that reduces the exploration space effectively without decreasing recognition rate. The Korean finger language is divided into 3 categories according to the direction of a wrist, and a model can be searched within these categories. Pre-classification can discern a similar finger Korean language. And it makes a search space to be managed effectively. Therefore the proposed method can be applied on the real-time recognition system. Experimental results demonstrate that the proposed method can reduce the time about three times than general HMM recognition method.

The purpose of this study is to verify if there is any difference on researchers' language preference for citing documents in different subject fields. 8 scientific journals were selected one of each from 8 main categories, given by National Research Foundation of Korea. Five variables including the rate of citing domestic and foreign documents for each journals were choose, and the differences on language preference among researchers of different subject fields were checked by implementing ANOVA. As a result, there are some differences on language preference, in terms of the average number and percentage of foreign documents, among researchers, based on their subject background. It also found that 8 subject categories divided into 4 small clusters.

This study developed HanScript, which is an educational Hangul programming language, in order to make programs easily and conveniently and applied it to the school fields. To evaluate HanScript, additionally, the researcher divided the properties of educational programming languages into easiness to read, easiness to write and easiness to debug and, based on them, compared HanScript with Visual Basic. According to the result, HanScript was expressed in Korean language style, so was easier to read and debug than Visual Basic. But it was not different from Visual Basic in debugging. Due to fewer libraries compared to Visual Basic, however, it was difficult to implement complex functions using HanScript. In addition, HanScript did not include an editor to edit source codes. Thus, if HanScript is equipped with rich libraries, detailed debugging information and an editor for source code edition, it will be a useful educational programming language.

This study is designed to find out how the recognition of the listener's role affects listening in Korean language learning. We assumed that recognizing the role of the listener can focus on important information. To confirm our assumption, we conducted an experiment on 37 Koreans and 32 KSLs. Koreans and KSLs were divided into two groups depending on whether or not they recognize the role of the listener. The results showed that Koreans and KSLs who recognized the role of the listener were better at listening to important information, and Koreans who recognized the role of the listener were better at judging important information. This study suggests that the role of listeners as context apply to Korean listening education.

OWL(Web Ontology Language) is the Ontology Standard Language and the a lot of Ontologies are being constructed in OWL. But the research on the extension of OWL is also progressing because of the limit of representation power of in OWL language. The W3C suggests the SWRL(Semantic Web Rule Language) based on the combination of OWL and RuleML(Rule Markup Language), which is improved in the representation of rule. Thus, both OWL and SWRL are used for developing ontologies. However, research on inference of ontologies written in both languages is just begun. These day, for the inference of ontologies written in both languages, ontologies and divided in to two parts. The part written in OWL and written in SWRL. For the inference of the part written in OWL, Racer, a DL based inference engine, is used and for the other part Jess, a rule-based engine, is used. In this paper, we will propose three methods for integrated inference of the OWL part and the SWRL part of ontologies using Jess and some tools for ontology inference : OWLJessKB and SWRL Factory

The purpose of this study is to review the perspective on early childhood language education by analyzing language activities specified in the Teacher's guide to Nuri Curriculum for Children between Age 3 to 5. In the pursuit of this purpose, 966 language educational activities suggested in 32 guidebooks(10 for age 3, 11 for age 4, 11 for age 5 - divided by life themes) have been chosen as the analysis object and analyzed based on the following category; subordinate scope, and activity type. This analysis showed that children aged 3~5 start their language activities in the order of talking, listening, reading and writing (under the subordinate scope category), and favors activities in the order of 'fairy tale/poem', 'story telling' and 'verbal section'. In conclusion, it has been proven that each category is concentrating on 1~2 activities and the proportion varies depending on the age. Based on the above result, we intend to examine the current situation of language education and use this study as the preliminary data to provide a proper direction for early childhood language education.

The purpose of teacher education is to improve the professionalism of teachers above the current level. The type of teacher education to improve the professionalism of experienced teachers is broadly divided into top-down education and bottom-up education. So far, studies on top-down education were commonly conducted in the field of Korean language education. However, there has been an increasing number of studies emphasizing the need for bottom-up education, driven by the voluntary participation of teachers in recent years. The purpose of this study is to suggest the direction of reflective teacher education for experienced Korean language teachers. For this purpose, a survey was conducted of 71 Korean language teachers who had more than 5 years of experience. The contents of the survey consisted of opinions regarding existing teacher education, the need for reflective teacher education, and the perception of teaching professionalism. The results showed that experienced Korean language teachers had a positive perception of the existing teacher re-education experience. Also, 91% of the respondents said they intend to participate in the reflective teacher education program. In particular, respondents showed high demands for 'peer coaching', 'peer observation', and 'teaching portfolios' among reflective teacher education programs. Lastly, many respondents selected 'development and utilization of teaching materials', 'encouraging learner's utterances', and 'leading learner's interest and motivation' as sub-elements of teaching professionalism that they wish to improve through teacher re-education.

The purpose of present study was to investigate the characteristics of disfluency between the Korean-English bilingual and Korean monolingual children, matched by their chronological age with the bilingual children. Twenty-eight children, 14 bilingual children and 14 monolingual children participated in this study. The experimental tasks consisted of the play situation and the task situation. The conclusion is (a) The score of total disfluency of the bilingual was significantly higher than that of the monolingual. The score of normal disfluency of the bilingual was significantly higher than that of the monolingual. The most frequent type is Interjection in both groups. All shows higher score in the task situation than the play situation. The bilingual children have quantitative and qualitative differences in disfluency score and types from the monolingual. (b) The bilingual were divided into two groups such as 6 Korean-dominant bilingual and 8 English-dominant bilingual. All shows more disfluency in their non-dominant language. The most frequent type is Interjection in both groups. (c) The higher the chronological age and the expressive language test score is, the lower the disfluency score is. The earlier the exposure age to the 2nd language is, the higher the disfluency score is. There is no correlation between resident month at foreign country and the disfluency.

This article examines the ways in which language can be exploited in the manipulation of the reader's interpretation of a text to make him/her take certain lines of thought according to the writer's persuasive intents. Such functions of language provide valid foundations to support the teaching of critical reading skills and to explore an adequate approach to discourse analysis. A pilot study was conducted to find out the extent to which the reader can be coaxed into thinking in some fashions guided by specific linguistic devices employed for ideological texts. Forty-seven subjects divided into two groups (humanities majors and natural science majors at undergraduate level) joined the two-fold questionnaire surveys intended to look at their critical reading abilities. The empirical results indicate that college students whose majors are humanities were more inclined to take a holistic approach in processing commercial advertisement texts and their abilities for critical interpretation appeared to be lower than those of the subjects whose majors are natural sciences, who showed a relatively high tendency to take an analytical approach in decoding the textual facts. As a consequence, pedagogic implications for increasing critical reading abilities have resulted in a set of analytical procedures concerning ideological texts which is linked with instructional guidelines to emphasize the importance of the reader's logical and analytical reasoning power, entirely accepted as a general prerequisite for cracking the covert language gambits.
