신경망 확산망을 이용한 항만물류 연속 음성인식시스템에 관한 연구
이창민,장종칠,이춘근 東義大學校産業技術開發硏究所 2003 産業技術硏究誌 Vol.17 No.-
항만 물류 시스템의 인간공학적인 설계가 요구되고 있다. 특히 물류(컨테이너)의 선, 하적시 컨트롤 문제는 인간에게 과부하를 주고 있어 시스템의 음성화가 요구되고 있다. 본 연구에서는 연속음에서 음성구간을 추출하여 각 음성을 확산필터뱅크를 통해 특징을 추출하고 신경망 인식기에서 인식하여 인식결과를 항만물류 음성인식시스템에 사원번호 인식에 사용하였으며 사원번호 입력화면에서 숫자로 디스플레이 되도록 설계하였다. 인식결과는 각 숫자음과 "확인", "삭제" 등으로 나타내었다. 전체적으로 인식률은 96%을 보이고 있으며 100% 인식결과를 나타내는 음도 있었지만 숫자 "사"의 경우 인식률 80%로 약간 낮은 결과을 나타내었다. 추후에는 패턴의 다양화와 전 처리에서의 개선 등으로 문제점을 보완 하여야 할 것이다.

This study focuses on changes in the kinds of flowers, colors, shapes of bridal bouquet in Korea for 50 years from 1950's to 1990's. The results show that two to three kinds of flowers were used in 1960's and 1970's, but various materials were used in 1980's and 1990's. White chrysanthemums rank first in 1950's and 1960's, carnations in 1970's, but roses and cymbidiums in 1980's, and use of cymbidiums, roses, and denphalae increased in 1990's. When it comes to foliage, camellia leaf used most frequently until 1960's and Asparagus in 1970's, but use of various tropical foliage such as scindapsu, ivy, Rumora fern increased in 1980's. In colors, white was most preferred in 1950's and 1960'sl pink was added in 1970's, but both white and pink were used in bouquet and boutonniere in 1990's. In shape, large arm bouquet was most preferred in 1950's. Round bridal bouquet with long asparagus stem was most favorite style in 1960's and 1970's, cascade shape and empire bouquet in 1980's, and various bridal bouquet such as cascade, round, triangular and free style in 1990's. In boutonniere they used triangular most frequently.

This study was conducted to have basic and applied informations to establish the cultivation method and to improve the cultivation techniques of Angelica gigas Nakai through investigating the rates of germination and seedling establishment with treatment of plant growth regulator and seed priming. The germination rates of round shape seed were about 0.3~12% higher than those of parallel shape. The germination rates with different storage durations were increased at the level of 25oC and 4oC with the storage days, while they were clearly higher at -20oC compared to those at 4oC and 25oC without the storage durations. With the results of germination rates with treating of plant growth regulator and seed priming, their rates with the round shape seeds were comparatively higher about 6% than those with parallel shape seed and they were increased with increasing of the storage durations. The germination rates were generally appeared higher with GA3 than did those with seed priming. The highest germination rate was appeared at 50 ppm GA3 of plant growth regulator and at -0.5 MPa PEG6000 of seed priming. The germination rates?ㅤ ?ㅤ of Angelica gigas were different with different temperature, storage durations and the treatments of plant growth regulator and seed priming. These results could be used according to different cultivating conditions.

3,9-Dihydro-6-oxopterocarpen과 ferulic acid의 에스테르 반응을 통해 페룰산 유도체인 3,9-diferuloyl-6-oxopterocarpen (Tensolin-F<sup>®</sup>)를 합성하여 이를 함유한 주름개선 화장품을 개발하였다. Tensolin-F<sup>®</sup>는 농도 의존적으로 DPPH와 superoxide radical에 대한 소거효과를 나타냈으며, 각각 0.8 mM에서 78%, 0.053 mM에서 92.9%로 DPPH와 superoxide radical을 소거하여 우수한 항산화 효과를 나타내었다. MMP-1 효소 활성 저해 효과도 0.16 mM에서 74%를 저해하였다. HDF에서 UVA에 의해 발현이 증가되는 MMP-1의 발현 저해 효과는 Tensolin-F<sup>®</sup> 0.8 uM에서 85.5%로 단백질 수준에서 모두 농도 의존적으로 발현 저해효과가 나타났다. Tensolin-F<sup>®</sup>를 함유한 제품의 피부 주름개선 효과 평가 결과, Tensolin-F<sup>®</sup>를 함유한 화장품을 약 8주 간 도포한 경우 유의한 주름개선 효과가 있음을 확인 할 수 있었다. 본 연구를 통하여 Tensolin-F<sup>®</sup>는 항산화 효과와 MMP-1활성 저해 효과 및 UVA에 의한 MMP-1의 발현을 저해하는 효과가 나타났으며 새로운 주름개선 기능성 화장품으로 이용될 수 있을 것이다. As a novel anti-wrinkle agent, 3,9-diferuloyl-6-oxopterocarpen (Tensolin-F<sup>®</sup>) has been synthesized and its anti-aging effects have been investigated. In the present study, to investigate the relationship between aging and Tensolin-F<sup>®</sup>, we examined its effect on scavenging activities of radicals and reactive oxygen species (ROS), in vitro inhibition activity of matrix-metalloproteinase (MMP) and expression of UVA-induced MMPs in human dermal fibroblasts (HDF). Tensolin-F<sup>®</sup> was found to show activities of scavenging radicals and ROS with the IC<sub>50</sub> values of 0.2 mM and 0.95 mM against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and superoxide radicals, respectively, in the xanthine/xanthine oxidase system. Fluorometric assays for the proteolytic activities of MMP-l (collagenase) were performed using fluorescent collagen substrates. Tensolin-F<sup>®</sup> inhibited the activities of MMP-l in a dose-dependent manner and the IC<sub>50</sub> values calculated from semi-log plots were 0.025 mM. Also, UVA induced MMP-1 expression was reduced 85% by treatment with Tensolin-F<sup>®</sup> at 0.8 uM, which was reduced dose-dependent manner. The results of clinical study showed that 4.8 mM Tensolin-F<sup>®</sup> treated group reduced wrinkle significantly compared with placebo treated group (P<0.05). Taken together, these result suggest that Tensolin-F<sup>®</sup> act as an anti-wrinkle agent by taking effects to antioxidation and reducing UVA-induced MMP-l production.-l production.

<P>Flavonoids and related compounds exhibit a wide range of useful pharmacological properties but present challenges related to their stability and solubility in commonly available solvents. In this study, polymethyl methacrylate (PMMA) microcapsules were prepared using a novel polyol-in-oil-in-polyol (P/O/P) emulsion solvent evaporation method as a means of stabilizing the flavonoids, using quercetin as a model flavonoid drug. The morphology of the microcapsules was evaluated using a scanning electron microscope, revealing a spherical shape with a smooth surface. The cross-section image of the PMMA microcapsules prepared with an amphiphilic polymer in the inner polyol phase showed that the microcapsule was filled with several submicron microspheres. The mean diameter varied from 1.03+/-0.12 microm to 2.39+/-0.42 microm, and the encapsulation efficiency ranged from 12.7% to 26.9%. When free quercetin was stored at 42 degrees C, the residual quercetin content gradually decreased to 18% over 28 days as a result of oxidation. However, when encapsulated in PMMA microcapsules with an amphiphilic polymer in the inner polyol phase, the residual quercetin content decreased to just 82%. In-vitro release studies indicated a sustained release pattern throughout the 36-h study. The release kinetics of the microcapsules with an amphiphilic polymer followed a diffusion-controlled mechanism and the microcapsule without amphiphilic polymer followed an anomalous diffusion behaviour. This study suggests that the novel P/O/P emulsion solvent evaporation method can be applied to the encapsulation of flavonoids.</P>

<P>Mouse breast regression protein 39 (BRP-39; Chi3l1) and its human homologue YKL-40 are chitinase-like proteins that lack chitinase activity. Although YKL-40 is expressed in exaggerated quantities and correlates with disease activity in asthma and many other disorders, the biological properties of BRP-39/YKL-40 have only been rudimentarily defined. We describe the generation and characterization of BRP-39<SUP>−/−</SUP> mice, YKL-40 transgenic mice, and mice that lack BRP-39 and produce YKL-40 only in their pulmonary epithelium. Studies of these mice demonstrated that BRP-39<SUP>−/−</SUP> animals have markedly diminished antigen-induced Th2 responses and that epithelial YKL-40 rescues the Th2 responses in these animals. The ability of interleukin13 to induce tissue inflammation and fibrosis was also markedly diminished in the absence of BRP-39. Mechanistic investigations demonstrated that BRP-39 and YKL-40 play an essential role in antigen sensitization and immunoglobulin E induction, stimulate dendritic cell accumulation and activation, and induce alternative macrophage activation. These proteins also inhibit inflammatory cell apoptosis/cell death while inhibiting Fas expression, activating protein kinase B/AKT, and inducing Faim 3. These studies establish novel regulatory roles for BRP-39/YKL-40 in the initiation and effector phases of Th2 inflammation and remodeling and suggest that these proteins are therapeutic targets in Th2- and macrophage-mediated disorders.</P>

Delftia acidovorans is a gram-negative motile rod found ubiquitously in soil and in water. Confirmed isolation from clinical infections is rare, and has been documented mostly in immunocompromised patients or those with indwelling catheters. A 53-year-old man was referred for the evaluation of a huge mass-like lesion found incidentally by chest X-ray. The lesion occupied more than half of the right lung and was diagnosed as a large loculated pleural effusion by CT scan. Bloody pus was drained through a percutaneous catheter, and D. acidovorans, identified by the Vitek GN card and confirmed by amplification of 16S ribosomal RNA and sequencing analysis, was isolated repeatedly from the drained pus. The patient was treated with imipenem/cilastatin to which the organism was sensitive. This is a rare report of chronic empyema associated with D. acidovorans in the respiratory system of an immunocompetent patient.
