Background and Objectives The objective of this study was to examine the effect of early cochlear implantation (CI) performed in infants less than 12 months of age. Subjects and Method Twenty-five children who received their first CI before 12 months of age were included in this study (infant group). The speech perception and language outcomes of these children were compared with those of 14 children who received their first CI between 13 and 24 months of age (older group). All children received sequential bilateral CI with the inter-stage interval of less than 2 years. Speech perception was measured using Categories of Auditory Performance, monosyllabic word test and sentence test, and language ability was measured using Sequenced Language Scale for Infants, Preschool Receptive-Expressive Language Scale, or Receptive & Expressive Vocavulary Test, depending on the age at the time of testing. Results There were no significant differences in speech perception abilities between the infant group and the older group. The mean expressive language score of infant group was higher than that of the older group, but the difference was not statistically significant. However, the receptive language score of infant group was significantly higher than that of the older group. Conclusion Children who received CI before 12 months of age achieved better receptive language ability than those who received it after 12 months of age. Thus CI should be performed as early as before 12 months of age to achieve better language ability.

This study was aimed to examine problem-solving ability of fifth graders on two types of mathematical essay problems, and to analyze the process of mathematical justification in solving the essay problems. For this purpose, a total of 14 mathematical essay problems were developed, in which half of the items were single tasks and the other half were data-provided tasks. Sixteen students with higher academic achievements in mathematics and the Korean language were chosen, and were given to solve the mathematical essay problems individually. They then were asked to justify their solution methods in groups of 4 and to reach a consensus through negotiation among group members. Students were good at understanding the given single tasks but they often revealed lack of logical thinking and representation. They also tended to use everyday language rather than mathematical language in explaining their solution processes. Some students experienced difficulty in understanding the meaning of data in the essay problems. With regard to mathematical justification, students employed more internal justification by experience or mathematical logic than external justification by authority. Given this, this paper includes implications for teachers on how they need to teach mathematics in order to foster students' logical thinking and communication.

This study examined whether self-correction or metalinguistic explanation might make a difference in the ability to accurately write two English grammatical structures when learners received indirect teacher feedback in the form of underlining target errors in a Korean EFL college classroom. With the goal of helping low-proficiency students improve their ability to accurately write sentences including nonfinite present participial relative clauses and present participial constructions, four groups were formed: a group which received indirect feedback, a group which received indirect feedback and metalinguistic explanation, a group which received indirect feedback and self-corrected errors, and a group which received indirect feedback and self-corrected errors after receiving metalinguistic explanation. The results showed that the effects of either metalinguistic explanation or self-correction integrated with indirect feedback on learners' ability to accurately write the target structures were not meaningful, while the combined effects of metalinguistic explanation and self-correction were statistically significant.

The purpose of this study is to compare the difference in the interactions between beginning language learners and heritage learners on their forms based on the interaction hypothesis. In this study, three types of information gap activities were used to analyze Language Related Episodes (LREs) while investigating the interaction patterns in language use between four pairs (eight learners) of foreign learners and four pairs (eight learners) of English-speaking heritage learners. The result indicated that foreign learners had a high focus on form during interaction. In particular, they had a tendency to focus on vocabulary rather than grammar, and they conducted self-repair by examining and mostly adjusting their speech to postposition and tense. However, in the problem-solving process, they showed a limited ability in interaction, and thus directly asked others to settle the problem or resorted to using English due to their lack of ability to employ various communication strategies. However, heritage learners had a relatively low focus on form compared to foreign learners. Yet, they also focused more on vocabulary rather than grammar and conducted self-repair in interaction, especially for vocabulary. In addition, they were skillful at using various communication strategies such as indirect expressions, use of alternative words, evasion, and delaying, to expand speech and prevent communication breakdown. They focused less on grammar and mostly did not provide negative feedback in interaction.

청각장애 아동은, 듣고 발화하는 과정을 통해 언어를 재구성해가는 건청 아동과는 달리, 청력의 손실로 인해 언어 습득의 선천적 메커니즘이 작용될 수 없다. 따라서 청각장애 아동의 언어능력 향상을 위해 웹 기반 언어학습 시스템은 이들의 언어학습 특성에 적합하게 구성되어야 한다. 청각장애 아동을 위한 웹 기반 언어학습 시스템을 설계할 때 동작이나 상황을 나타내는 말을 동적으로 구현하고, 사물 및 행동에 대한 관찰력을 증진시킬 수 있도록 주도적인 상황언어학습의 시스템 구성이 필요하다. 그리고 대체사고전략의 활용과 얼굴표정의 강조, 반대어와 대비어의 활용이 시스템 구성에 적용되어야 한다. 이 연구에서는 청각장애 아동의 문법적 오류의 감소와 언어학습의 향상을 도모할 수 있도록 이들의 특성에 적합한 언어학습 시스템을 제안한다.

The purpose of this study was the investigation of theoretical and empirical relationships between Piagetian and psychometric assessments of intelligence. Specifically, the factor structure of Piagetian-type scales, the relationship between Piagetian scales and psychometric intelligence tests, and differences in the factor structure of Piagetian and psychometric assessments of intelligence were studied. The subjects of this stuby were 70 children (35 boys and 35 girls) in the 1st grade of an elementary school in Seoul The Piagetian-type scales and the K-WISC were administered individually, and the General Intelligence Test was administered to groups of children. Statistical analysis of the obtained data consisted of the SPSS Computer program including factor analysis and Pearson's product moment correlation coefficient. The Piagetian-type scales were found to consist of three factors, which accounted for 55 percent of the total common-factor variance. Factor-I was a factor indicating "conservation". Factor-II was a factor indicating "moral judgements". Factor-III was a factor indicating "classification and identity". Correlations between subtests of psychometric tests and Piagetian scales were relatively low or moderate. Relations between IQs assessed by the psychometric tests and Piagetian scales were also relativeyly low or moderate. Eight factors were extracted from the joint factor analysis of psychometric intelligence tests and Piagetian scales, and they accounted for 67 percent of the total common-factor variance. Factors-I, II, III, and V consisted of subtests of psychometric assessments, and Factors-IV, VI, VII and VIII were composed of Piagetian scales. Factor-I was a factor for "reasoning ability based upon language". Factor-II was a factor for "performance ability". Factor-III was a factor for "grouping ability". Factor-IV was a factor for "conservation". Factor-V was a factor indicating "symbol and language usage ability". Factor- VI was a factor indicating "moral judgments". Factor-VII was a factor indicating "length consevation". Factor-VIII was a factor indicating "classification and identity".

This study aims to explore the potential of Korean language learning as a means of psychological healing and improving the quality of life for Japanese middle-aged and older learners. Results showed that Korean language learning could help alleviate various psychological issues experienced by middle-aged learners and contribute to enhancing their quality of life. Learning a foreign language is not just about acquiring information but also about meeting people who use the language and understanding and experiencing their culture. In particular, for Japanese middle-aged learners, Korean language learning can be advantageous as it can lead to the discovery or development of new hobbies or interests. Results also showed that Korean language learning increased learners' opportunities for interaction with others and enjoyment of learning new cultural customs. These positive outcomes suggest the need for discussion of teaching strategies that focus on psychological healing in foreign language education. Further clinical trials with participants who learn foreign languages for healing purposes may provide more conclusive evidence on the diverse effects of language learning on stress, anxiety, depression, self-development, social connections, and cognitive ability.

Objectives : The purpose of this study was to provide basic materials for defining educational direction of dental hygiene department and establishing the instruction to improve direction consulting and academic effect of dental hygiene department student. Methods : The researcher surveyed the relation among job aptitude, academic ability and academic performance by selecting 131 dental hygiene department students of P university as study targets. Results : For high school classifications, direction searches and academic abilities of dental hygiene department students of P university, it was found that classical high school was 68.7% and vocational high school was 31.3%. For job aptitude, social type was 58.0% and artistic type was 26.0% so they were usual. For academic ability, interpersonal relation($12.78{\pm}1.34$), music/rhythm was($12.32{\pm}1.09$) and natural($12.32{\pm}1.00$) showed high scores in order over the first, the second and the third field and language/vocabulary(22.6%) and music/rhythm(21.6%) was the next. For academic performance depending on high school classification, job aptitude and academic ability, there was a significant difference in high school classification by classical high school($86.55{\pm}8.21$) and vocational high school($85.34{\pm}11.31$)(p<0.05) and there was also a significant difference in job aptitude by social type($85.45{\pm}9.42$) and artistic type($88.41{\pm}6.93$)(p<0.05). In the mutual relation between academic ability and academic performance, the high academic ability score in the first field was led to the high score in the second and the third field, showing significant mutual relation(p<0.00). Conclusions : This research has been accomplished by college students of dental hygeine department, so you have to consider before generalizing these results. Therefore it is required to research more, likewise using a comparison with other students or it should be conducted by general people.
