This case study investigated the assessment and treatment of bilingual children using a 4.5 year old bilingual child. We also compared treatment methods for bilingual children in the U.S. and in Korea, respectively. Given the lack of unbiased assessment tools, it was difficult to evaluate the child properly. In addition, the study of the linguistic characteristics of bilingual children have not been researched extensively in Korea. As a result, there were limitations in assessing the child. However, once all requisite information had been gathered, he was assessed as a bilingual child with specific language impairment (SLI) and his skill in both languages was considered equivalent. During treatment sessions, the child exhibited diverse linguistic characteristics and interesting error patterns which were not evident in monolingual SLI. However, it was difficult to assess whether the error patterns exhibited by the subject were attributable to his own bilingual characteristics or not. This was further complicated by the lack of previous research on the bilingual child's linguistic characteristics. His progress differed from one area to another. Furthermore, we illustrated some of the limitations in assessing bilingual children and proposed several considerations that should be met before treatment is initiated.

ISO 14649 (data model for STEP-NC) is a new interface scheme or language for CAD-CAM-CNC chain under established by ISO TC184 SCI. Up to this point, the new language is mainly made for milling and turning, and other processes such as EDM will be completed in the future. Upon completion, it will be used as the international standard language for e-manufacturing paradigm by replacing the old machine-level language, so called M&G code used since 1950's. With the rich information contents included in the new language, various intelligent functions can be made by the CNC as the CNC knows what-to-make and how-to-make. In particular, On-Machine Inspection required for quality assurance in the machine level, can be done based on the information of feature­based tolerance graph. Previously, On-Machine inspection has been investigated mainly for milling operation, and only a few researches were made for turning operation without addressing the data model. In this thesis, we present a feature-based on-machine inspection process by the 4 Tasks: 1) proposing a new schema for STEP-NC data model, 2) converting the conventional tolerance scheme into that of STEP-NC, 3) modifying the tolerance graph such that the tolerance can be effectively measured by the touch probe on the machine, and 4) generating collision-free tool path for actual measurement. Task 1 is required for the incorporation of the presented method in the ISO 14649, whose current version does not much include the detailed schema for tolerance. Based on the presented schema, the tolerance represented in the conventional drafting can be changed to that of STEP-NC (Task 2). A special emphasis was given to Task 3 to make the represented tolerance accurately measurable by the touch probe on the machine even if the part setup is changed. Finally, Task 4 is converting the result of Task into the motion of touch probe. The developed schema and algorithms were illustrated by several examples including that of ISO 14649 Part 12.

Objectives : The purpose of this study is to provide the basic data for searching for the method to induce more positive knowledges and attitudes about the old from the university students majoring in dental hygienics, health and social welfare university students majoring in the old, who will face the change of aging society directly. Methods : The study selected 1 school in Busan and Daegu respectively with convenience sampling from September 2010 to October 2010, performed questionnaire(self administered questionnaire) to 401 students majoring in dental hygienics, health and social welfare and achieved following conclusions. Results : 1. When the students without the education experience about the old have negative experiences, the degree of interest in the old was high and when they have positive experiences, the attitude score about the old was high(p<0.001). 2. For education experience about the old, the students majoring in dental hygienics have the lowest experiences(p<0.001). 3. For knowledge, attitude and behavior about the old depending on major, the students majoring in social welfare have the highest interest and for the knowledge about the old in physical area, the students majoring in health have the highest knowledge(p<0.01).4. The area related with the knowledge about the old showed significant correlation in all of physical, psychological and social area(p<0.001). 5. The factors giving effects to the attitude about the old were gender(p=.006), experience(p=.003) and education experience related with the old(p=.022) and the factors giving effects to the behavior about the old were experience(p=.036) and attitude about the old(p=.000). Conclusions : It is necessary to develop actual education program that can provide preliminary dental hygienists with positive attitude about the old and reflect a lot of matters related with psychological area and social area about the old. In addition, it is necessary to establish the opportunity to understand the old through voluntary service activity related with the old in connection with local community. It is necessary to recognize the old positively by showing the positive figure.

The aim of this study is to provide some information on frequencies of occurrence for units of Korean phonemes and syllables analysing spontaneous speech spoken by 3 to 8-year-old Korean children. 49 Korean Children(7${\sim}$10 children for each age) were employed as subjects for this study. Speech data were recorded and phonemically transcribed. 120 utterances for each child were selected for analysis except one child whose data were only 91 utterances. The data size of the present study were 5,971 utterances, 5,1554 syllables, and 105491 phonemes. Among 19 consonants, /n/ showed highest frequency rate of these four conson ants were over 50% for all age groups. Among 18 vowels, /a/ was the most frequent one and /i/ and / ${\wedge}$ were the second and third respectively. The frequency rate of these four consonants were over 50% for all age groups. Frequently occurring syllable types were a part of grammatical word in most cases. Only 5${\sim}$6% of syllable types covered 50% of speech.

The purpose of this study was to investigate the diadochokinetic characters in the patients with spastic cerebral palsy(CP) in severity. The diadochokinetic characters were measured through rate, regularity, accuracy and consistency. The subjects participated in this study included 27 persons with spastic CP(mild- 9, moderate- 9, severe- 9) and 9 normal persons who is around 11-20 years old. On the result of this study, rate in AMR was significant difference between all spastic groups and normal group, and rate in SMR was significant difference between normal and mild groups and moderate and severe groups. In regularity of diadochokinetic task, severe group had significant difference the other groups. Finally, accuracy and consistency of diadochokinetic task exhibited significant difference between all spastic groups and normal group.

The aim of this study was to examine the articulation characteristics of preschool children in the bilingual or monolingual environment. Subjects included 23 children of 4 to 6 years old in the bilingual environment, and 19 children of monolingual environment. Their speech was evaluated in terms of articulation correctness and intelligibility by the author and a speech therapist. Results showed as the following: First, there were some significant differences between bilingual and monolingual children in the percentage of consonants correctly articulated. But there was no significant difference between their language environment or ages in the percentage of vowels correctly articulated. Second, there were some significant differences between the bilingual and monolingual children in the intelligibility of word articulation. Also, there were some significant differences between the two language groups in the sentence intelligibility. There was a high positive correlation between the word and sentence intelligibility.

What has been rapidly changed and developed is not only technology, but also language and culture, of which the diverse consensus has been speedily formed between generations and spread throughout all the social grades. Therefore, Neologisms need to be understood as part of the cultural history that is created at each period. We cannot keep neologisms, initially formed among the youths, from spreading all over the generations, not just for their enjoyment, convenience, and familiarity, but more for the fact that they are impossible to be replaced in use. Another reason is that a community is created according to language. The youths would like to make distance from the existing community by building an invisible wall of new language. This paper is intended to deal with neologisms, centered on visual pun. The characteristics of the Neologisms are the result of the tendency of the younger generation to avoid interference and to enjoy adding ingenuity to the existing order.That is why in all ages Neologisms are created, and although they differ in form, the principles of new word generation are old. We will also consider the historical characteristics of neologism in this paper.

This study examined the vocabulary competence of institutionalized and home-reared 6- and 7-year-old children with the use of the Revised Picture Vocabulary Test(Dunn & Dunn, 1981; Korean version, Kim et al., 1995), administered to 113 institutionalized children and 124 middle class home-reared children. Results indicated that the vocabulary competence of institutionalized children was inferior to that of home-reared children. Children who had lived in an institution for two years or more scored lower than those who had been institutionalized for a shorter time. 7-year-olds scored higher than 6-year-olds, regardless of institutionalization. Home-reared girls scored higher than home-reared boys, but there was no sex difference between institutionalized children. These findings suggest that efforts should be directed toward improving the linguistic environment of institutionalized children.

This study investigated the relations of children's age, intelligence, and the concept of conservation to their learning of English. Ten 4-year-old children from 1 child-care center and 13 7-year-old children from 1 elementary school were tested after completion of 8 sessions of experimental English classes. Children's intelligence was measured by K-WPPSI for 4-year olds and K-WISC for 7-year-olds. Children were tested for number and liquid conservations. A Korean teacher with 11 years of experience of teaching children at American elementary schools taught the 2 groups with the same subjects and methods. Data were analysed by independent samples t-test, Mann-Whitney U test, and Pearson's r. The results showed that children's age and the concept of conservation were related to English learning. No statistically significant relationship with IQ was found.
