The purpose of this paper is to establish the standard method of evaluation English-to-Korean MT systems We focus on test suites, evaluation procedure and evaluation results. Four computer programs on the market are tested on a test suite consisting of 1,501 sentence, The quality of translation and the capacity of MT system are the key points for evaluation . The sentences in the suite are classified according to the grammatical properties they reveal. The classificatory scheme has the structure of a directory: each sentence belongs to a subclass, which belongs to a major class,. We place the sentences in the test suite on a scale of difficulty (hard ordinary easy) and each output sentence is graded on a scale of four accuracy levels. We also test the programs with respect to their speed.

Knowledge in linguistic rhythm of the target language plays a major role in foreign language proficiency. This study attempts to discover valid rhythm features that can be utilized in automatic assessment of non-native English pronunciation. Eight previously proposed and two novel rhythm metrics are investigated with 360 English read speech tokens obtained from 27 Korean learners and 9 native speakers. It is found that some of the speech-rate normalized interval measures and above-word level metrics are effective enough to be further applied for automatic scoring as they are significantly correlated with speakers' proficiency levels. It is also shown that metrics need to be dynamically selected depending upon the structure of target sentences. Results from a preliminary auto-scoring experiment through a Multi Regression analysis suggest that appropriate control of unexpected input utterances is also desirable for better performance.

Since the term, 'scientific literacy' was introduced by P. D. Hurd in 1958, it has been used as a term, representing major goals in science education. In Korea, the term 'scientific literacy' was used in the statement of the summative objective of the 2007 science reformed curriculum. But in various educational contexts m which teachers and researchers works, the definition of the term has not been used consistently. This phenomena would be interpreted as showing limits of the term describing the goals of science education. This study examined the historical change in the meaning of the term in purpose of trying to anchor the definition. In this study, the changing period was divided into before introducing the term and after. The after era was divided into the period of confusing and anchoring in the meaning, and the period of expanding the meaning. Especially, after science as intellectual ability was conceptualized in science education communities, the meaning of scientific literacy was partially confused. In current time, as the concepts of language in cognitive science influenced the use of language in science education, the trends of expending the meaning of scientific literacy has been grasped in science education community.

Recently, Deep learning analysis of unstructured text data using language models, such as Google's BERT and OpenAI's GPT has shown remarkable results in various applications. Most language models are used to learn generalized linguistic information from pre-training data and then update their weights for downstream tasks through a fine-tuning process. However, some concerns have been raised that privacy may be violated in the process of using these language models, i.e., data privacy may be violated when data owner provides large amounts of data to the model owner to perform fine-tuning of the language model. Conversely, when the model owner discloses the entire model to the data owner, the structure and weights of the model are disclosed, which may violate the privacy of the model. The concept of offsite tuning has been recently proposed to perform fine-tuning of language models while protecting privacy in such situations. But the study has a limitation that it does not provide a concrete way to apply the proposed methodology to text classification models. In this study, we propose a concrete method to apply offsite tuning with an additional classifier to protect the privacy of the model and data when performing multi-classification fine-tuning on Korean documents. To evaluate the performance of the proposed methodology, we conducted experiments on about 200,000 Korean documents from five major fields, ICT, electrical, electronic, mechanical, and medical, provided by AIHub, and found that the proposed plug-in model outperforms the zero-shot model and the offsite model in terms of classification accuracy.

In this study, specific teaching methods of lecturing and improved discussion methods (combining discussion and problem-based learning) were selected and applied for each major subject and learning content area in the fields of engineering, language, and social sciences. Then, the selected teaching methods were examined to determine the most effective learning contents. Finally, in order to determine the most effective teaching methods, a survey on student satisfaction was analyzed statistically. The results showed that students preferred teaching methods that combine lectures and improved discussion methods to the traditional method of only lectures. Therefore, this research proposes the combined teaching method for each major subject and learning content area.

Objectives : The purpose of the study is to investigate the influencing factors on English interest and anxiety in dental hygiene students. Methods : A self-reported questionnaire was filled out by 1,040 dental hygiene students in six universities in Busan and Gyeongnam from April 1 to 30, 2013. The questionnaire consisted of general characteristics, foreign language performance anxiety scale, and English interest. The data were analyzed using descriptive statistics, independent t-tests, one-way ANOVA, and multiple regressions. Results : Those who travelled abroad tended to have a liking for English. English credits significantly influenced on English interest. and employment. The period of English study was proportional to interest and grade of English. Conclusions : The interest and anxiety for English was the major factor to improve the mastery of English. The dental hygienists must try to improve the mastery of language proficiency.

The prepositional object (PO) of an active sentence in English can sometimes be passivized, becoming the subject of the corresponding passive sentence. In particular, the verb (V) and preposition (P) in the English prepositional passive (P-Passive) are assumed to be reanalyzed to form a single structural unit, giving the status of a verbal object to the PO to be passivized. However, not every V+P sequence can undergo reanalysis, permitting the passivization of POs. Thus, we have to explain what licenses the reanalysis of V and p. resulting in an acceptable P-Passive sentence. In this paper, I will identify the factors which determine the passivization possibilities of POs and explain how they interact with one another. The results of this study will illustrate how formal and functional factors work together to form a major syntactic construction and to determine its grammaticality and acceptability.

For the past 20 years the process approach to writing has been popular in second language writing classrooms. However, there have been very few studies conducted in Korea with regard to the composing processes and the effects of proficiency on writers' usage. The present study attempts to begin to fill this gap. Three groups of college students with different writing proficiency participated in the study: the advanced group, the intermediate group, and the beginning group. The verbal protocol of their writing processes revealed that they approached writing tasks differently. While the advanced writers focused on generating texts and ideas and examined their writing at both global and local levels, the other two groups of students tended to focus on evaluating text at the local level and generated fewer ideas and less text. The findings from this study are then compared to those of some major studies of the composing process as conclusions are subsequently drawn about the specific needs of Korean college writers.

In an attempt to identify highly probable causes of poor EFL performances, certain intriguing data of 11 common errors collected from 23 university students' listening and reading for correction of a short conversation of three people, with a questionnaire regarding their knowledge of the situational context, were analysed and interpreted within a theoretical framework of consciousness and the intonation unit (Chafe 1974, 1980, 1994), compatible with some important philosophical and psychological theories. The results: situational understanding does not always guarantee good EFL performances; the 11 errors were not attributable to hearing problems; consciousness appropriate for literacy and formal schooling appeared to be the major cause, which was inappropriate for a communicative use of English. Re-shaping of consciousness was suggested, with a warning against the ‘grammar consciousness raising’ approach.
