The purpose of this paper is to show how the coda of a syllable and word-final clusters are represented in the English syllable structure. Previous theories on the syllable assume that there is only one segment in the coda position. And, as we know, the theories that license only one segment in the coda make it difficult to syllabicate the word-final cluster appropriately when more than two segments in the word-final cluster are encountered. I considered three approaches: the previous syllable structure (Selkirk, 1982; Borowsky 1989), sonority sequencing (Giegerich, 1992; Roca, 1999) and feature analysis (Goldsmith, 1990), But, all the considered methods don't give us a satisfactory explanation regarding word-final clusters. Finally, I will suggest a modified syllable representation as an alternative by placing two different appendixes under the Phonological Word which forms a constituent above the syllable node. From this it is possible to explain the former problematic word-final clusters including morphological information asan inflectional suffix in the structure.

This study aims to discuss the word sense distinction of Korean middle verbs for restructuring KorLexVerb 1.0. Despite the duality of its meaning and syntactic structure, the word senses of middle verb are not clearly distinguished in current dictionaries. The underspecification causes very often mismatches that a same Korean word sense is used for two different English verb senses. A close examination on the syntactic and semantic properties of middle verb shows us that the word sense distinction and the reconstruction of hierarchical structure are indispensable. Finally, by doing this fine grained word sense distinction, we propose an alternative way of classification and description of the verb polysemy for KorLexVerb 1.0 as well as for dictionary-like language resources.

PURPOSE: People with physical disabilities such as cerebral palsy usually experience obstacles when interacting with computer through conventional keyboard because of their motor disabilities. The purpose of this study is empirically compare of text entry(alphabet and word) speed and accuracy using the three different keyboard type on four students(male 2 and female 2) with cerebral palsy. METHODS: This research design used a replicated single-case experimental approach to compare the individual performance. An alternating treatments design was used to examine the effectiveness of standard QWERTY keyboard and alternative keyboard(mini and big keyboard) on computer access for students with cerebral palsy. To avoid changes in posture that influence a keyboard character entry training and evaluation was carried out using his sitting in a wheelchair. Compass software program used in this study as an assessment tool to measure speed and accuracy when performance of text entry(alphabet and word). This was repeated until the stable status of reaction time. RESULTS: As a result, the alternative keyboard seems to be the most effective device for students with cerebral palsy to perform text entry. But various factors such as peculiarity of motor disabilities, experience and preferences of the user are heavily related. CONCLUSION: Thus, we must perform the objective and systematic assessment for computer access and if sustained training is accomplished, it could to improve speed and accuracy of text entry(alphabet and word).

There is linguistic phenomenon that Korean syllable, morpheme and word are substituted with Chinese Character. These phenomenon is called Chinese Character Borrowing, the Chinese character used here is called Borrowed Chinese Character. Whereas borrowing Chinese character in Chinese is used for borrowing only sound for different word, borrowing Chinese character in Korean is used for assigning new meaning. Hence, by borrowing Chinese character in Korean, a syllable which had no meaning originally get new meaning, morpheme and word meaning has changed. At advertisement and campaign, Chinese Character Borrowing has lots of linguistical advantage such as visual immediacy, effectiveness of meaning expression. However, there are number of cases found that violate grammar rule and word constitution practice by Chinese Character Borrowing. For this reason, Chinese Character Borrowing has the problem polluting Korean along with another foreign words. Thus, this paper focus on study Chinese Character Borrowing phenomenon in Korean, and analysis its effectiveness and impact in Korean. In addition, analysis the problem of Borrowed chinese Character, and suggestion several alternative for right use of Korean is followed.

This study collects and analyzes data on educational philosophy and method for domestic and overseas alternative schools. This information is then applied to educational purpose and curriculum for a home economics curriculum that develops unique characteristics for Korean alternative education.This study collected and analyzed the characteristics of educational content and educational elements from two renowned alternative schools: Waldorf School in Germany and Summer Hill in the United Kingdom. The research results were as follows. First, it is necessary to create new word instead of using the term 'alternative education'. Second, among characteristics of Korean home economics curriculum, 'practical problem-solving ability', 'independent living ability', and 'relation forming ability' should be utilized to create a school with an independent curriculum and to establish a unique brand value. Third, time investment on instructor education should be made to cultivate competent and charming instructors as the center of a school. Lastly, school education should manage student's life at school and after graduation. The school and instructor should provide alternative education while thinking they are responsible for 50 years of a student's future life. This study helps show that alternative education is not perceived as a superficial and generalized education and that Korean alternative education can find similar characteristic to those of overseas cases.

Purpose Even if many startups firms have developed innovative items and a potential for success, they often have a limited financial resources, which makes them difficult to do business. To overcome this financial difficulty, startups have used one of fintech services, called crowdfunding that can be a good alternative to solving the difficulty of financing. The purpose of this study is to empirically validate the proposed research model that investigates the reasons of trusting crowdfunding platform, which positively leads to two outcomes - intention to participate and word-of-mouth for reward-based crowdfunding project. Design/methodology/approach We proposed several factors categorized as trust, information quality, and platform traits that have a positive impact on trust of crowdfunding platform, which positively leads to intention to participate and word-of-mouth of crowdfunding. The collected(n=285) from individuals who have participated in crowdfunding project was analyzed with SmartPLS 3.0 to test proposed hypotheses. Findings The results showed that all proposed variables (website reputation, crowdfunding familiarity, digital storytelling, information quality, and interaction) had a significant impact on crowfunding platform trust with exception of product differentiation. In addition, crowfunding platform trust was positively associated with participating intention and word-of-mouth. Based on findings, we discussed the research results and implication alone with a direction for future studies.
