This study investigated the effect of vocabulary learning strategy education on lexical diversity of L2 Korean learners’ writings. Before the experiment, the study surveyed 136 L2 Korean learners on what vocabulary learning strategies are effective and elicited three strategies such as using idioms, having conversation with native speaker, and imaging words. The study employed 35 Chinese L2 Korean learners at TOPIK intermediate level and allocated them into 4 experiment groups with three strategy groups and a control group. Learners’ writings were collected before and after the 4 week education and were analyzed to measure lexical diversity by TTR and D_optimum average. The study found out that there was huge improvement of lexical diversity in using idioms group and having conversation with native speakers group; and the latter is even bigger. Based on the results, this study claimed that the appropriate education of vocabulary learning strategies is necessary to improve lexical diversity of L2 Korean learners’ writings.

The goal of this study is to investigate word- formation by reducing. If ‘dol(돌)’ means the young and popular singer and ‘dol’ has high productivity, it can say that ‘dol’ has the characteristics of element-only-for-word formation. ‘Chirengseu(치렝스)’ is similar to ‘beugeum(브금)’ in word-formation considered Korean syllable structure. But ‘chigingseu(치깅스)’ is a reduced word by the same way of English word-formation. The reduced word ‘beugeum’ is used for expressing the meaning of ‘Background Music’ rather than reflecting its phonetic value. In ‘beugeum’, ‘ㄱ’ is the result of trying to mark ‘ground’ and ‘rengseu’ is the result of similar trying. The formation of Bauer’s acronym ‘beugeum’ is different from Bauer’s abbreviation ‘bijiem(비지엠)’.

This study analyzed Korean language learners’ interlanguage to examine the learners’ Korean speech act of Prohibition. The analysis was made focusing especially on the learners’ mother tongue. Based on the result, this study discussed the education Korean speech act education of Prohibition according to their mother tongue(Chinese, Japanese, Mongolian, Vietnamese) This study is meaningful in that it was the first attempt to clarify the aspect of Korean speech act of Prohibition through analysing the interlanguage. Previous studies focused on the fact that learners produce similar errors, irrelevant of their mother tongue. But this study intended to reveal that ‘speech acts’ is largely effected by the learners’ mother culture and language, and therefore could be made by them. Among the 9 prohibition situations presented in this paper, 7 situations showed prohibition speech acts vary by their mother tongue. Therefore, an accurate analysis and understanding of the features and strategy of the learners’ interlanguage by their mother tongue will lead to speech education with higher efficiency.

By analyzing the meaning of the lexemes possessing the property of the value that has been recognized as a relationship of the attention, this research intends to present a plan that can be utilized in the Korean language education through the objective data and materials. At this time, the lexemes possessing the property of the value are the value, the price, the charge, the cost, and the lexeme that has extended the form. It is not easy to accurately present the differences of the meanings of the lexemes which exist in the relationships of the attention to the foreigner learners whose Korean language is poor. In most of the cases, the differences of the meanings are presented according to the intuition of the teacher. As, at this time, the mistaken vocabulary information reflecting the subjectivities of the teacher can be delivered, the information that has been organized with the objective data and materials in the background is needed. For this, regarding the lexemes that are the subjects of the discussions, the information provided in the Korean Standard Unabridged Dictionary shall be used. With this in the background, in Chapter 2, the basic meaning and the extended meaning possessed by each lexeme are organized. Also, regarding the diverse lexemes, each of which has been formally extended, the core meanings shall be understood. They shall be categorized by the semantic property. And these shall be presented through the tables. With such results in the background, in Chapter 3, by classifying the lexemes of which the domains that can be substituted exist, whether or not they have the relationships of the attention shall be understood. And there shall be the discussions on the plans that can present the differences of the meanings to the learners.

A study on the compare of olfactory adjectives in Korean and Japanese. This study aims to compare the semantic similarities and differences of Korean and Japanese olfactory adjectives based on the lexical semantics. First of all, I classified according to meaning. The eight kind of basic olfactory adjectives in Korean ‘향내, 고린내, 노린내, 비린내, 고소한내, 지린내, 매운내, 쉰내’ and corresponding to Japanese ‘かぐわしい(kaguwasii), 臭(くさ)い(kusai), 獣(けもの)臭(くさ)い(kemonokusai), 生臭(なまぐさ)い(namakusai), 小便臭(しょうべん)臭(くさ)い(syoubenkusai), かび臭(くさ)い(kabikusai), 饐(す)え臭(くさ)い(suekusai)’. And they are classified again according to shape. I analyzed the olfactory adjectives types and forms of Korean and Japanese, and also find out their similarities and differences. Furthermore, I delineated primary meaning and meaning extension, meainng transfer idiom of Korean and Japanese olfactory adjectives. The olfactory adjectives of Korean were used in more productive way in sense of meaning and form than that of Japanese. In this sense, the Korean olfactory adjectives were rather more used in the productive way than the Japanese were. In conclusion, we have looked at one of many discussions of these meaning transition; smell to taste given the example of ‘고소하다, 구수하다’-‘香ばしい(koubasii)·芳ばしい·馨しい(kanbasii), かぐわしい(kaguwasii)’, and 臭(くさ)い(kusai)-‘구리다.’ By comparing of Korean and Japanese olfactory adjectives, I understand the exact meaning and usage of Korean olfactory adjectives and based on this study, I expect the result of research will be helpful in use of Korean language education.

The learning of synonyms helps Korean learners to use vocabulary accurately and precisely, to improve their vocabulary. However, the opportunity to encounter various words with synonymous relation for foreign learners is few and because their intuition is still developing, they may experience difficulties in differentiating and using synonyms. The aim of this study is to identify semantic preferences based on existing research of semantic categories of the combination relation of vocabulary and use this to help in the semantic distinction of synonyms. Using a corpus, each lexical combination aspect of synonym families was identified and by conducting an analysis of synonyms and lexical combination, the tendencies were also identified. Therefore, this type of study can provide important information in compiling a dictionary and be used in a vocabulary education setting.
