The purpose of this study was to investigate the characteristics of fundamental frequency(F0) and amplitude distributions in persons with cerebral palsy(CP) in the reading task. Participants were divided into three groups: 6 persons with spastic CP, 6 persons with athetoid CP and 6 normal persons who are around 15-20 years old. On the results of this study, firstly, in F0 distributions, most of the spastic CPs tended to appear narrow distributions on the basis of mode, but most of the athetoid CPs were opposite, and both of the CP groups tended to distribute highly on lower and higher frequencies than mean and mode. On the other hand, normal persons had a tendency to appear narrow distributions on the basis of mode. Finally, in amplitude distributions, the spastic CPs showed a tendency that there are little differences between the distribution of mode and the others, and most of the athetoid CPs showed a tendency that the distributions of mode were higher than the others. In addition to, the normal persons had a tendency that the distributions of mode were remarkably higher than both of the CP groups.

The purpose of this study was to investigate diadochokinetic (DDK) characteristics in the subjects with spastic cerebral palsy (CP) by severity. DDK characteristics were measured through rate, regularity, accuracy and consistency in Alternate Motion rate (AMR) and Sequential Motion rate (SMR) tasks. The subjects participated in this study included 27 subjects with spastic CP (mild- 9, moderate- 9, severe- 9) and 9 normal persons who are 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 the DDK tasks, severe group had significant difference the other groups. Finally, accuracy and consistency of the DDK tasks exhibited significant difference between all spastic groups and normal group. In conclusion, the subjects with spastic CP have a tendency to produce slow and irregular syllable repetition as severity increases, but to produce inaccurate and inconsistent syllable repetition regardless of severity in the DDK tasks.

The effects of binder on the mechanical properties of the preforms and metal matrix composites (MMCs) were studied. Fibers were $9Al_2O_3{\cdot}2B_2O_3(Alborex)$, HTZ and $Al_2O_3$ fibers(Saffil) and binders were organic binder, inorganic binder, polyacrylamide under various PH conditions. Compressive strength of the preform increased with the addition of inorganic binder. The polyacrylamide did not improve the permeability of the preforms. PH of the slurry should be controlled because it affects the viscosity of the slurry. Good preforms were obtained under following conditions : 3 wt% inorganic binder, 0.1 wt% organic binder, 0.1 wt% polyacrylamide and PH 9. Tensile tests of MMCs were conducted at $20^{\circ}C,\;150^{\circ}C,\;250^{\circ}C,\;350^{\circ}C$ using MTS(100KN USA). Wear tests were conducted under various sliding speeds. High temperature($250^{\circ}C$) tensile strengths of Alborex/Saffil/AC8A and HTZ/AC8A are 80% and 75% of the room temperature tensile strengths respectively. The tensile and wear properties of the Alborex/Saffil/AC8A are superior to that of the HTZ/AC8A. The wear behavior of HTZ/AC8A shows more orthotropic characteristic than that of Alborex/Saffil/AC8A.

Purpose: Following tooth extraction caused by severe periodontitis, alveolar ridge dimension lose their original volume. To reduce the alveolar ridge dimension, the ridge preservation technique has been introduced and tested in many clinical studies with membrane alone or membrane plus graft, achieving reduced ridge loss compared to extraction only. The aim of the present clinical study was to compare the post-extraction dimensional changes in the membrane exposure group to non-exposure group during healing period following ridge preservation technique. Methods: Ridge preservation was performed in 44 extraction sites. After extraction, deproteinized bovine bone mineral coated with synthetic oligopeptide (Ossgen-$X15^{(R)}$) or deproteinized bovine bone mineral (Bio-$Oss^{(R)}$) was implanted into the socket. A collagen membrane (Bio-$Gide^{(R)}$) was trimmed to cover the socket completely and applied to the entrance of the socket. Four clinical parameters were compared between baseline and 6 months. Results: During healing period, membrane exposure was observed at 19 sites. At the re-entry, hard newly formed tissue were observed at the ridge preservation site. The grafted socket sites were well preserved in their volume dimension. In both groups, horizontal ridge width was reduced and vertical height was increased. There were not statistically significant differences in horizontal (-1.32 mm vs -1.00 mm) and vertical ridge change (2.24 mm vs 2.37 mm at buccal crest, 1.36 mm vs. 1.53 mm at lingual crest) between two groups. Conclusions: The ridge preservation approach after tooth extraction effectively prevented resorption of hard tissue ridge in spite of membrane exposure during healing period.

The purpose of this study was to compare the characteristics of the subsystems for speech production by the types of Cerebral Palsy (CP) by applying various tasks and measurements that can evaluate the characteristics of respiratory, phonatory, resonant, articulatory, and prosodic systems. The subjects were 32 speakers with spastic CP, 17 speakers with athetoid CP, 10 speakers with ataxic CP, and 35 CP-free speakers. The experiment was conducted by analyzing 13 sub-items and 27 parameters in four tasks (prolonged vowel utterance, diadochokinesis, counting, and reading). The conclusions obtained from this study were as follows; First, there were significant differences between speakers with CP and those without, but there were no differences among the types of CP in the characteristics of the respiratory system. Second, there were significant differences between speakers with CP and speakers without CP, but there were no differences among the types of CP in the characteristics of the phonatory system. Third, there were generally similar characteristics between speakers with CP and those without, but speakers with athetoid CP tended to differ with CP-free speakers in two tasks (diadochokinesis and reading), and there were no differences among the types of CP in the characteristics of the resonant system. Fourth, there were significant differences between speakers with CP and CP-free speakers in the characteristics of the articulatory system. Among the types of CP, speakers with athetoid CP had differences with speakers with spastic CP, but speakers with ataxic CP had no differences with speakers with spastic and athetoid CP in diadochokinetic tasks. Fifth, there were significant differences between speakers with CP and CP-free speakers, but there were no differences among the types of CP in the characteristics of the prosodic system. In conclusion, speakers with spastic, athetoid, and ataxic CP had similar characteristics in the subsystems for speech production, but they tended to differ by tasks in the articulatory system.
