The WE DSP32 in AT&T's second-generation programmable digital signal processor with 32-bit floating point arithmetic. This device can be used in a wide varity of complex digital signal processing algorithms such as speech recognition,high speed modems, low-bit rate voice coders, and multichannel signaling system. This paper reviews the LPC analysis and synthesis of speech signal and presents a real time implementation methodology of these algorithms using the WE DSP32. For efficient data handling, circular buffer is proposed. The implementation results show that deep pipelining characteristics of the processor should be fully utilized to satisfy the timing constraints,

The purpose of this study was to evaluate the relationship between osteoporosis and periodontal condition in postmenopausal women. Twenty-eight patients who have been treated at Chonnam nationa university hospital with osteoporosis(osteoporotic group, mean age 62.2±6.6) and 21 normal postmenopausal women with periodontitis(control group, mean age 60.4±3.7) were examined. Bone mineral density(BMD) of lumbar spine(L2-L4) was measured by dual energy X-ray absorptiomemtry(DEXA). Percentage to peaked bone mass in osteoporotic group was 70.9% which had lower BMD than in control group(p<0.05). The number of present teeth were 23.6 in osteoporotic group and 23.1 in control group. Percentage of bleeding on probing was 41% in osteoporotic group and 37% in control group. probing depth and attachment level were shown 3.18 mm, 3.63 mm in osteoporotic group and 2.85 mm, 3.11 mm in control group, respectively. probing depth and attachment level were significant greater in osteoporotic group than in control group(p<0.05). The significant negative correlation was found between BMD level and periodontal attachment level(p<0.001, γ=-0.56). These results suggest that osteoporosis may be associated with periodontal breakdown.

This study was conducted to investigate the reference value of mercury (Hg) in liver and kidney of Korean population. The mercury concentration in 244 'sudden and unexpected death' autopsies (male: 180, female: 64) aged from 0 to87 years was analyzed. The concentration of mercury was measured by atomic absorption spec(Perkin -Elmer Model 5100) with mercury/hydride generating system (FIAS 400). The contents of mercury in liver and kidney fitted well the log-normal distribution rather than normal distribution. Geometric mean concentration of mercury in liver and kidney was 0.115 ㎍/g wet weight and 0.149 μg/g wet weight, respectively. Geometric mean concentration of mercury in female was higher than in male (p<0.01). The mercury content in liver and kidney increased with age up to the forties and slightly decreased there-after, The regression model of mercury deposit in liver and kidney by age was predicted as the following equation : Log KHg=-1.0576+0.0045·Age -0.0001·Age²+0.0873·Sex, Log KHg=-1.0576+0.0152·Age-0.0002·Age²+0.1935·Sex. The liver burden of mercury was estimated to be 158.3~161.3μg in male and 163.0-166.9 ㎍ in female. The kidney burden of mercury was estimated to be 42.0~42.9 ㎍ in male and 55.5 ∼57.1 μg in female.

The purpose of this study was to observe the effect of TGF-81, which promotes differentiation and proliferation of osteoblasts, on bone regeneration. Experimental bone defects that measured 3 mm in diameter were created on the mandibles of guinea pig by removal of bone with the use of trephine burs. In one side of mandibular body, the experimental groups, bone defects were grafted with Biogran(Orthovita Co., U.S.A.) and TGF 131(R&D System Co., U.S.A.). In the remaining side of the mandiblar body, the control groups, bone defects were grafted with only Biogran. Guinea pigs in the control and experimental groups were serially terminated by fours on the 3 days, the 1 week, the 2 weeks, the 3 weeks, and the 4 weeks after experiment, and both sides of the mandibular bodies were removed and fixed with 10% neutral formalin. They were decalcified and embedded in paraffin as using the usual method. The specimen sectioned and stained with hematoxylin and eosin. Also, they were radiographed with a soft X-ray apparatus. The Obtained results.=were as follows; 1. Hemorrhagic condition, observed in the granulation tissues, disappeared on the 1 week after experiment in both groups, and more prominent in the experimental group. The granulation tissues of the experimental group had larger number of cells than those of the control group. 2. Osteoblastic differentiation in the margin of grafted material and adjacent bone was observed on the 1 week after experiment in both groups. Also, bone formation was observed in immature form on the 1 week after experiment, and more prominent in the experimental group. 3. In the polarizing microscopic examination, bone matrix was very loose on the 1 week after experiment, but increase in density with time, and more prominent in the experimental group. 4. In the microradiographic examination, newly formed bone was observed in the experimental group on the 2 weeks after experiment, and this was observed earlier than in the control group. Newly formed bone was increased with time and defected area was markedly decreased on the 4 weeks after experiment.

Nevus lipomatosus cutaneus superficialis is very rare malformation consisting of multiple or solitary papules usually occuring on the lower trunk or glutesl regions. Microscopically it reveals groups of ectopic fat cell nests within the dermis. The authors observed two cases of typical nevus lipomatosus cutanes superficaialis. The first case was a 30-year-old female who has had asymptomatic, soft, skin colored and huge confluent tomor masses on the left buttock for 10 years; the second case was a 21-year-old male who has had multipel, soft, skin colored papules on the right buttock for 10 years. The author, made diagnosis of nevus lipomatosus cutaneus superficialis from characteristic clinical and histopathological findings. Related literature was briefly reviewed for the discussion.
