In augmenting the Oriental noses with silicon implants Dong's guider innovated and has been applied to faciliation of the surgery among the population of the cosmetic cases of more than 70,000 in the Peiple's Republic of China. Using Dong's guider takes the operation time only three to five minutes and attains to high efficancy. This new technique is merely simple and lessens the patient's distress.

Objectives : This study was done to evaluate present status of child and adolescent psychiatric practice in the view of medical consumers. Help seeking behaviour process after recognizing their children's problem, satisfaction with psychiatric service, and difficult problems during practice were evaluated, and variable factors affecting them were analysed. Methods : Through 10 multi-center point epidemiologic survey, 540 parents and their psychiatrists were involved in this study by structured questionnaire. Results : Above 70% of subjects reported positive response to psychiatric service. The barrier to psychiatric service were different by subjects' age. In children, Parents' inability to identify severity of children's problem and proper management place were major reason. However in adolescent, children's lack of desire to receive help and parents' worry about stigma related to receiving help were major barrier to psychiatric service. Conclusion : These findings suggest the importance of interagency collaboration and education services. Researchers and policymakers should consider strategies to reduce barrier related to perceptions of mental health problems and services, especially in adolescents.

Ferromagnetic material like the steel tubes can easily distort eddy current testing signal due to increased magnetic permeability for defects. Because magnetic field of the test probe is affected in an inconsistent way when the material under the testing has permeability. This permeability effect can be reduced by magnetic saturation. In this paper eddy current testing system was developed to detect flaws on the steel tubes. Magnetic saturation probe with helmholtz coil was designed for saturation and inspection of the steel tubes. When using the designed test probe, the relationship between flaw signals and noises was obviously discriminated. Additionally, a high pass filter was included in the eddy current board to minimize noises due to DC magnetic field.
P Element in Drosophila melanogaster

In the early 1970s, P elements have been discovered by male recombination in Drosophila melanogaster. P elements have revealed much about the molecular structure, mechanism of exicision and transposition, evolution of transposable elements. By serving as mutagens, transposon tags, and transformation vehicles, they have opened new approaches to many other questions in wider area of Drosophila genetics.

The purpose of this study is to testify the pattern making method to develop the men's basic bodice pattern using 3-dimensional body scan data. The experimental patterns were made by adding wearing ease on flattened body scan data and tracing the outlines of it. The experimental bodice pattern were composed of front, back, and side panels. To compare the difference between the experimental pattern and traditional pattern, two pattern making methods were compared. Two sets of basic bodice patterns were made for each of the 10 male subjects: a set of pattern was made by experimental method and the other set was made by Bunka pattern making method. The experimental and traditional patterns were measured at 13 dimensions. The results show that there was a difference between the experimental patterns and traditional patterns at the front length, back length, front width, front neck width, back neck width, and back neck depth. The fit was also compared for both patterns. The results of the fit test show that the experimental patterns were superior to the traditional patterns at the fit of neck, shoulder, and armhole. The experimental pattern making method was expected to be useful for mass customization.

Object: Many studies on the effect of long-term treatment with anticonvulsant on thyroid function in children have been reported. Because the mechanism and metabolism of each drugs are different, the effect of anticonvulsants on thyroid function is controversial. And it has been reported that competitive binding with serum protein, increased intrahepatic excretion and more recently effects on hypothalamus and pituitary gland make changes in thyroid hormones. Therefore, we checked T₃, T₄, TSH levels of the patients who have been taking anticonvulsants for more than 1 years, in order to the influence of carbamazepine and valproic acid on thyroid function. Method: 38 patients (male 18, female 18) who have been diagnosed as epilepsy during the period of Jan 1996 to Dec 1996 at SoonChunHyang University Hospital, and being treated with anticonvulsant, the serum levels of triiodothyronine(T₃) thyroxine(T₄) and TSH were measured were measured by RIA. Result: Of these 38 patients, 18 were males and 18 were females. The mean age of the patients was 9.46 ±3.86(2 to 17 years old) years old. In 10 cases were treated with valproic acid, in 7 cases received carbamazepine and in 11 cases were treated with combined therapy. In valproic acid treated group, T₃, T₄, TSH levels were 145.05±25.34ng/dl, 8.86±2.17㎍/dl, 2.73±0.86 μU/ml respectively. In Carbamazepine treated group. T₃, T₄, TSH levels were group, T₃, T₄, TSH levels were 162.06 ±26.78ng/dl, 9.66 ±4.18㎍/dl 2.01 ±0.78 μU/ml respectively. Although the levels of T₃, T₄, TSH were within normal range, they were relatively decreased compared to the control group. The carbamazepine treated group was revield lower T₃, T₄ levels compared to those treated with valproic acid, but we couldn't find out statistical significance. Conclusion: In our study we found out long-term treatment with anticonvulsants including carbamzepine and valproic acid had effects on thyroid function and follow-up test with larger group of patients should be proceeded.

Organizations face an environments of continuous and accelerating change. An Increasingly pervasive response to this experience is to engage in some form of downsizing. Our research contends that without strategic approach to downsizing, downsized companies can't achieve a reduction in overall labor costs and increase in productivity. So managers must plan and execute a well-orchestrated strategies of downsizing in their organizations. A strategic approach to downsizing requires that managers ⑴ formulate a vision of the future of the organization ⑵ clearly define downsizing goals ⑶ take actions to develop member's ability ⑷ continuously communicate with unions and members, in order to share with vision, goals, and downsizing methods ⑸ design incentive systems necessary to support member's behavior change.
