Design of turbo-compressors has been considered to be a high-tech which only a few early industrialized countries could do efficiently since it requires not only deep understanding of high level gas dynamics and complex fluid dynamics but also accumulation of experiences in the feedback of expensive manufacturing and difficult testing to the design theory and empirical design coefficients. CFturbo is the turbomachinery design software which incorporates traditional well formulated German design technology and latest software technology of 3-dimensional graphics. Fine/Turbo is a powerful tubomachinery-oriented CFD package with quality structured grid topology templates for almost all the tubomachinery configurations for easy, fast and accurate CFD analysis. Rapid and effcient process off turbo-compressor R&D is setup with the combination of CFturbo and Fine/Turbo.

The hypothesis was tested that children whose families differ in socioeconomic status(SES) and educational level differ in their rates of productive language development because they have different language-learning experiences. Naturalistic interaction between mothers and their children was video taped. Transcripts of these interactions provided the basis for estimating the growth in children's productive vocabularies and properties of maternal speech. The sixty children from age 1 to 3 were selected in Yanji, China. The results show that the high educated mothers' children grew more than the low educated mothers' children in their mean length of utterances. Properties of maternal speech that differed as a function of mother's educational level fully accounted for this difference. Implications of these findings for mechanisms of environmental influence on child development are discussed.

In South Korea, some interethnic families result from prearranged marriages where 1 spouse is an immigrant. In this study, traits of children in families of interethnic immigrant marriages were studied by individual interviews of ten kindergarten teachers responsible for them and 8 observations of their preschool classes. Subjects were 21(13 male, 8 female) 3- to 5-year-old children. Results showed the diverse traits of these children : they adapted to the environment by changing and getting along, but some of them exhibited problematic behavior such as delayed language development, confused identity, and aggression. The attitude of their peers included passive reaction, discord and receptivity regarding their difference. The attitude of the teachers was a sense of responsibility and worry.

Language learning involves linguistic environments around the learner. So the variation in training input to which the learner is exposed has been linked to their language learning. We explore how linguistic experiences can cause differences in learning linguistic structural features, as investigate in a probabilistic graphical model. We manipulate the amounts of training input, composed of natural linguistic data from animation videos for children, from holistic (one-word expression) to compositional (two- to six-word one) gradually. The recognition and generation of sentences are a "probabilistic" constraint satisfaction process which is based on massively parallel DNA chemistry. Random sentence generation tasks succeed when networks begin with limited sentential lengths and vocabulary sizes and gradually expand with larger ones, like children's cognitive development in learning. This model supports the suggestion that variations in early linguistic environments with developmental steps may be useful for facilitating language acquisition.

Sympathetic dysfunction is one of the possible complications of anterior spine surgery; however, it has been underestimated as a cause of complications. We report two successful experiences of treating severe dysesthetic pain occurring after anterior spine surgery, by performing a sympathetic block. The first patient experienced a burning and stabbing pain in the contralateral upper extremity of approach side used in anterior cervical discectomy and fusion, and underwent a stellate ganglion block with a significant relief of his pain. The second patient complained of a cold sensation and severe unexpected pain in the lower extremity of the contralateral side after anterior lumbar interbody fusion and was treated with lumbar sympathetic block. We aimed to describe sympathetically maintained pain as one of the important causes of early postoperative pain and the treatment option chosen for these cases in detail.

Experience with intracardiac surgery in infants indicates that for most anomalies the operation and late mortality after primary total correction is lower than the combined mortality after early palliation and delayed correction. In addition, there are secondary benefits of primary total correction in terms of reversal of retarded physical growth and social development and alleviation of parental anxiety. One hundred and fifteen infants under 2 years of age with congenital cardiac anomalies underwent primary surgical intervention at Seoul National University Hospital from Jan. `78 to Sep. `82. There were 70 patients with VSD, 17 patients with TOF, 10 patients with TGA, 4 patients with ASD, 4 patients with TA, 3 patients with TAPVR, and the remainders are Coronary AV Fistula, partial ECD+COA, SV, DORV, PA, Trilogy+PDA. The overall surgical mortality was 18.3%. In acyanotic group 6 patients died among 76 operated patients, and surgical mortality was 6.6%. But in cyanotic group, the mortality was very high as41.0% [16 patients among 39 patients]. This poor surgical result in cyanotic group was due to Improper pre-, intra- and post-operative care, and we are convincing that these factors soon be improved as experiences accumulated.

Purpose: The current descriptive study examined the health and healthcare status of preschoolers in poverty group compared to those of comparison group. Method: Data were collected from 51 mothers in federal poverty group and 49 in low-income group and 200 mothers in normal income comparison group in one city. The instruments used for this study were Korean CBCL and health related questionnaire. Results: Public assistance group showed more low-birth-weight infants, developmental delay, and hospital admission experiences. Their compliance for vaccination and congenital metabolic disorder test were lower than those of comparison group. Preschoolers' behavior problems were not significantly different depending upon the income of the group. Conclusion: Preschoolers' health and healthcare status are affected by the socioeconomic characteristics of the family. It indicated an need for anticipatory guidance and early intervention that might help to prevent or ameliorate potential health problems in poverty.

Robert Lowell is one of the major poets in the modern American poetic world. His major work, Life Studies, is a representative of confessional poetry. It presented American spiritual civilization and universality for life from the late 1950s to 1960s. It dealt with the subject of the poet's private life under the psychological pressure. Lowell described his distinctive vision of the relationship of painful world and suffering self in his poetry. An important feature of his confessional poems was the criticism on modern civilization by means of characterization. Life Studies was written as a kind of therapy to overcome his early trauma, as well as the social problems of contemporary Americans which Lowell was confronted with. Through his personal experiences, Lowell exposed and judged the collapse of traditional value and moral confusion in the society. Therefore, he is a poet who opened his own world of poetry with his poetic achievements.

Not all parents are skilled in scaffolding their young children's numeracy learning. The present study investigated the effectiveness of a parent training program in promoting Filipino young children's number sense via card game playing at home. Participants were 161 young children and their parents; families were of a relatively low socioeconomic status. During the 10-week intervention period, parents in the experimental group received training on how to use number game cards to help their children acquire various numeracy concepts; parents in the control group received no special instructions. Children in the experimental group showed greater improvements in their performance on six number sense tasks (namely numeral identification, object counting, rote counting, missing number, numerical magnitude comparison, and addition) over the intervention period than did children in the control group. Findings of the present study suggest that providing simple training to parents on strategies for fostering their young children's number sense at home is important for giving children a good early start in basic number knowledge.

This paper looks into the ideological discourse embedded in D. H. Lawrence's Sons and Lovers. Sons and Lovers is an autobiographical novel which necessarily carries the author's own experiences. For this reason, it reflects the social and historical background upon which the narrative is displayed. Sons and Lovers is full of the historical characteristics of the late-nineteenth- and early-twentieth-century England. This essay closely reads the class struggles of the time in Sons and Lovers. In most of Lawrence's novels, the class struggles appear in the form of the marriage of two people from different classes. In Sons and Lovers, the hegemonic conflicts between Walter Morel and Gertrude Morel clearly show the class struggles of the time. Also, this paper disentangles the complicated stories of William and Paul and shows the general tragedy of English young men of the time. In the end, it will show that Sons and Lovers is a fully loaded ideological discourse.
