  • This study investigated how Korean learners of English acquired the English reflexives. There is emphasis on the effects of the GCP and PAP(Wexler and Manzini, 1987). The purpose is to examine the major hypothesis that L2 learners are still constrained by Universal Grammar (UG), despite the influence of the parameter setting of their native language as well as the non-operation of the Subset Principle. The experimental group consisted of 30 middle school students (age 14-15), 30 high school students (age 16-17), and 30 university students (age 18-19) as well as 20 ESL students (age 16) studying English in the USA. Twenty native speakers of English served as a control group. The subjects responded to a test on reflexives that used a multiple-choice grammaticality judgement task. Findings show that L2 learners transfer their L1 parameter setting and, as a result, make errors in the choice of antecedents for reflexives. Therefore, I argue that the L2 learner is still constrained by UG.

  • The purpose of this study was to examine the relationship among infants' nonverbal communication, maternal verbal behaviors and the infants' acquisition of vocabulary. The subjects were 93 pairs of 10 to 18 months old infants and their mothers residing in the Seoul and GyeongGi-Do area. The results were as follows : (1) In terms of the infants' nonverbal communicative means, it appeared that the group of 16~18 month olds utilized more gesture and vocalization. As regards the infants' nonverbal communicative functions in terms of social behavior and joint attention, the group of 16~18 month olds was found to perform more of the behaviors from this category than the other groups. There was a significant difference in the maternal verbal behavior among the different age groups. (2) Among the infants' nonverbal communicative means, gesture and vocalization, there appeared to be a significant relationship between vocalization and the infants' acquisition of vocabulary. In addition, there was an important relationship between the high usage of infants' nonverbal communicative functions with behavior regulation and the high usage of joint attention and the successful acquisition of vocabulary among infants. (3) Social play, which is a maternal verbal behavior categorized as one of the strategies for getting infants' attention, was significantly related to the acquisition of infants' vocabulary. (4) When mothers used more imitating sounds and mimetic words, requests for information, descriptions, conventional social expressions, and imitation to enhance responsiveness, infants were found to have acquired a larger vocabulary.

  • The main goal was to evaluate effectiveness of a modified TSE sequence compared with DIR (double inversion recovery) sequence in acquisition of fast flow brain vessel images using signal void effect. 32 healthy volunteers (10 men and 22 women; mean age of 31 years; ranging between 28-43 years) who underwent black blood DIR sequence (group A) and the modified TSE sequence (group B) were enrolled in our study. Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) of the internal carotid arteries' lumen were compared in T1 and T2 weighted images for both group A and B. The images obtained from group B showed lower SNR values in internal carotid artery than the group A in both of the T1 and T2 weighted images (11.49% and 13.66% respectively). While the CNR values were higher in the group B than the group A in both of the T1 and T2 weighted images (8.69% and 7.55 % respectively). The qualitative score of all categories were not significantly different between the two groups. Furthermore approximately 49% of the total scan time was reduced from group B. Our study is to shorten the scanning time and minimize the inconveniences of the patients in acquisition of the black blood images of brain by using the signal void effect in the modified TSE technique while keeping the diagnostic value of the test.

  • The purpose of this study is to investigate opposites acquisition and tendency of processing negations about directional oppositionality from 3- to 6-old Korean children. The data were collected from 80 children from a daycare center and 20 university students in Busan, Korea. In Experiment 1, participants were asked to produce opposites for common terms related to colors, directions, and dimension adjectives. In Experiment 2, they were asked to make pictures corresponding to statements with negations(e. g. The arrow is NOT pointing up.). Summarizing the overall results, first, children over 5 considered 'blue' and 'red' as opposites colors in the case of not well-known color opposites. If there exists an opposite color, color opposites have been acquired from 6 year-olds, the directional opposites started from 3 year-olds, and the opposites of dimension adjectives did from 5 year-olds. Second, preferring the antipodal color opposites started from 6 and preferring the antipodal direction did from 3. Consequently, 3-to 6 year-old children acquired opposites at different age and opposites dimension. Also the opposites dimension have an effect on processing negation of young children.

  • This research examined the development in Korean children of the comprehension of complex sentences. The relative difficulty in comprehension of the temporal conjunctions "before" and "after" was investigated. The order of mention, contextual support, and syntactic appearance was controlled. The role of cognitive strategies and developmental changes in the comprehension of these conjunction was included in this study. Subjects were 90 preschool children between 3 and 5 years of age. The task was a sentence-picture matching problem having 3 types of sentences combining temporally with "before" or "after". The results were that developmental changes in comprehension of the temporal conjunctions "before' and "after" in Korean children depended on the order of mention, contextual support, and such syntactic factors as the position of the subject of the sentence. The importance of the consistency in the occurrence of events and the order of mention in the acquisition of complex sentences among Korean children is similar to the acquisition of complex sentences in other languages.

  • The purpose of the present study was to examine the role of semantic and syntactic knowledge in the first language acquisition of Korean classifiers. The elicited classifiers production test(EPT) was conducted to 105 children aged from 2 to 7. EPT consisted of 16 classifiers and two items for each classifier. 32 items were divided into 2 major semantic features: animacy and inanimacy. The semantic features of inanimacy were subcategorized into 3 features such as neutral, shape and function. The results revealed that; 1) children produced the correct structure of classification from the very early age with correct word order of the noun phrase showing early fundamental syntactic knowledge; 2) The earliest response pattern was to respond to all nouns in the same way using a neutral classifier showing no apparent semantic basis for their choice; 3) Children didn't show any preference for animate, shape, or function classifiers.

  • When certificates of qualification relating to computer have shown up like dam water and meeting the age of office automation (OA) utilizing computer throughout the community, and at the point of time when the promotion of efficiency of duty is attempted by utilizing internet, the improvement plans should be groped for to expect to cultivate the national industrial manpower efficiently and by easily approaching the related OA certificates of qualification related to computer so that everyone can acauire the additional points for recognition of credit, entering company and promotion by the dimension of public trust, recognition degree, practial using level in actual affairs, reliability of problems and after manpower management of the certificates of qualification less expensively and saving time. the concrete plans are as follows: First, in the standard of making questions for the examination of 'Computer Utilizing Ability' executed by the chamber of commerce and Industry, there is the independent examination, but by inserting the presentation portion in the higher grade and middle grade, it should be contributed to improve office efficiency both in mane and reality. Second, though the internet retriever's examination is executed by the nongovernment specialized examination, since it is actually widely utilized in the office activities due to universality of using internet, it is now the time to newly establish and accommodate it as the national examination of 'internet Utilizing Ability', not the interest specialized retriever. Third, the applicants, shall take examination for the nongoverment certificate of qualification or enterprise's certificate of qualification at the date and place designated by the applicant, but there are much restrictions for the national certificate of qualification, so the date of examination shall be decided flexibly and efficiently to give chances to students by adjusting to the semesters of the students. Fourth, in this rapidly changing age of the informationalization community, the acquisition of the certificates of qualification through the university and the designated and entrusted educational institutes should be increased the proportion of activation to become officially recognized, and the extent of special treatment for obtainers of the certificate of qualification should be expanded to equip manpower competitive power in the age of informationalization.

  • This study attempts to suggest a criterion of Korean language development. For this purpose we investigated speaking rates of the spontaneous utterances produced by 144 children, aged 3 to 8. We analyzed each subject's speaking rate and its relevance with speaker's age, gender and utterance length. To determine the relative contributions of variables to the speaking rate, multiple regression was conducted. Results of this study can be summarized as follows: (1) The mean and maximum values of the speaking rate increased with the growth of age. (2) A statistically significant increase in speaking rate appeared at two-year intervals. (3) There was no significant difference between male and female groups in the speaking rate. (4) The multiple regression analysis has shown that along with the speaker's age, the utterance length(the mean number of syllables per utterance) is also important in estimating the speaking rates.
