본 연구은 진해항 일대의 조류상을 조사ㆍ분석한 것이다. 조사는 2001년 12월부터 2002년 4월까지 28회를 조사하였다. 센서스 기간 중 총 61종의 조류를 조사 지역내에서 관찰할 수 있었으며, 연 55,115개체가 관찰되었다. 종수의 합계와 총 개체수 그리고 종별ㆍ개체별 출현 빈도에서 유도된 종 중요도는 불은부리갈매기[0.58], 괭이갈매기[0.14], 흰죽지[0.12], 고방오리[0.07], 민물도요[0.07], 참새[0.06], 재갈매기[0.06]가 중요한 종으로 나타났다. 월별 최대 관찰 개체수는 2001년 12월에 46종 5,993개체를 관찰하였으며, 2002년 1월에 37종 7,105개체, 2월에 37종 8,837개체, 3월에 38종 4,106개체, 그리고 4월에 32종 2,819개체를 관찰하였다. 종 풍부도는 4월에 가장 높게 나타났으며, 종 다양성과 균등도는 1월이 가장 높게 나타났다. 월별 종의 유ㆍ무와 개체수를 비교하여 양방향 유사도를 분석한 결과 2월과 3월의 조류 군집이 유사한(0.69: Pearson Correlation Index) 것으로 나타났고, 다음으로 1월(0.617), 12월(0.522)로 12, 1, 2, 3월이 하나의 cluster를 형성하고 있었으며, 4월이 틀린 cluster를 형성하고 있다. 수금류, 섭금류, 갈매기류, 참새류 등 4가지 중요 군집으로 구분하여 개체수를 비교한 결과 66%가 붉은부리갈매기 외 3종의 갈매기류였고, 21%가 혹부리오리 외 13종의 수금류, 7%가 붉은머리오목눈이 외 21종의 참새목, 5%가 흰물떼새 외 5종의 섭금류, 1%미만의 맹금류, 논병아리류, 가마우지류의 조류로 나타났다. We investigated the abundance and local distribution of birds, in four areas of the jinhae. Data were collected from four areas in the jinhae from 2001 to 2002. In this study, 55115 individual birds of 80 species were censused. We evaluated important species with abundance of birds were as follows: Black-headed Gull[0.58], Black-tailed Gull[0.14], Pochard[0.12], Pintail[0.07], Dunlin[0.07], Tree Sparrow[0.06], and Herring Gull[0.06]. The number of species and individuals in each month were recorded as follows: 5993 individual birds of 46 species in December(2001), 7105 individual birds of 37 species in January(2002), 8837 individual birds of 37 species in February, 4106 individual birds of 38 species in March, 2819 individual birds of 32 species in April. In study period, the april was the highset richness(R' =0.60) and the January was the highest diversity(H'=2.08) and evenness(E5=0.52) with an expected species number of E[S_(818)]=29. Pairwise similarity declined with increasing distance between recording month and recording month from two different clustered separately in a UPGMA cluster tree. Comparison of population variable at 4 sites of 4 classes was compared as follows: 1.Gull(66%), 2. Waterfowl(21%), 3. Passerine(7%), and 4. Wader(5%).

자동차의 air-bag 장치에 실용될 수 있는 압저항형 단결정 실리콘 가속도센서 칩을 개발하기 위하여 결정 실리콘 미세구조의 제조방법을 확립하고, 단위공정의 검증을 통하여 일괄공정에 의한 PROTO-TYPE 칩을 만드는 기술을 연구하였다. 단결정 실리콘 미세구조는 선택확산법을 이용하여 정확히 선택된 영역에만 air-gap을 형성하여 미세구조의 측면식각을 방지하는 선택확산법에 의한 실리콘 마이크로머시닝 기술로 제조하였다. 일괄공정을 위한 단위공정확립을 위하여 PROTY-TYPE 8빔 브릿지형 가속도 센서를 제조하였다. 제조된 칩의 가속도에 따른 출력전압은 선형성을 나타내고 있으며, 감도는 약 50 ㎶/V·g로 나타났다. 이 감도는 50G용 가속도센서의 사양을 만족하지 못했다. 이는 공정에 의한 문제라기 보다는 가속도센서의 시뮬레이션에 의해 설계한 구조가 이미 원하는 감도에 못 미친다는 것으로 생각된다. 따라서 2차 공정으로 제조될 가속도센서의 파라미터를 SuperSAP 유한요소 패키지를 이용하여 실리콘 미세구조부의 파라미터에 따른 특성을 시뮬레이션하였다. 설계된 50G용 가속도센서의 mass Pad의 반경 및 빔 길이, 빔 폭, 빔 두께, 그리고 mass의 각 파라미터 값은 700 ㎛, 120 ㎛, 5 ㎛, 1.0 ㎎ 이었다. 반도체 공정기술, 관성질량 제조법 및 선택확산을 이용한 마이크로머시닝을 사용하여 일괄공정으로 8빔 브린지형 가속도센서를 제조하였다. We researched the establishment of the silicon microstructure fabrication technique to develop a piezoresistive type silicon acceleration sensor chip and the technique to make a proto-type chip by the verification of the unit-process. Silicon microstructure is fabricated silicon micro-machining by selective diffusion method. This method prevent a side-etching of microstructure because selective diffused region is only formed an air-gap. We fabricated a proto-type 8-beam bridge-type acceleration sensor to establish the unit-process for the batch-process. The output voltage of the chip represented linearity with acceleration, and the sensitivity was about 50 ㎶/V·g. But this sensitivity dosen't satisfy the requirements of a practical acceleration sensor. The cause of this result is assumed not process problem, but the structure designed by simulation isn't suitable already. Threfore, the characteristics of parameters of the acceleration sensor that will be fabricated by 2nd-process is simulated by SuperSAP finite-element package. The determined parameter values of beam length, beam width, beam thickness, mass, and mass radius are 120 ㎛, 5 ㎛, 1.0 ㎎, and 700 ㎛, respectively. We fabricated 8-beam bridge-type acceleration sensor by batch-process using a semiconductor process technique, proof-mass fabrication method, and micromachinig using selective diffusion.

Purpose: Some patients who have undergone surgery due to lumbar disc herniation still complain of leg pain and other abnormal sensa tions. Therefore, the study examined the effects of the neurodynamics on pain and other abnormal nerve sensations in post-operated patients with lumbar disc herniation. Methods: The participants of this study comprised 20 adults (10 males and 10 females) who were diagnosed with lumbar disc hernia tion. The subjects were classified into two groups of 10 patients each in the lower extremity neurodynamics (LEN) and lumbar stabiliza tion exercise (LSE) groups. Each intervention was applied twice a day for one week and was composed of two different exercise patterns; one was applied by a therapist, and the other was performed by the patients themselves. The data were analyzed using assessment methods of Digital Infrared Thermal Imaging (DITI), Toronto clinical neuropathy scoring system (TCNSS), Sympathetic Skin Response (SSR) test, and Oswestry Disability Index (ODI) scale. Results: Significant differences in TCNSS, DITI, ODI scale were observed between the LEN and LSE group (p<0.01). On the other hand, there was no significant difference in the SSR test between pre and post-treatment (p>0.05). Conclusion: The results indicated that neurodynamics treatment is effective in pain reduction and abnormal sensations, such as leg muscle cramps, in post-operated patients with lumbar disc herniation.

수컷 SD 랫드를 사용하여, 핀탄수화물 급여군(HCHO), 탄수화물 및 지방 혼합 급여군(MPAT) 및 고지밟 급여군 (틴FAT), 그리고 절식군(R료I:T) 깊군을 체중웨 따란 완전임의 배치한 후 정제사료를 13주 동안 자옳 급식토록 하였다. 시험결과 체중에서는 절식관인 REST군을 제외하고 운의적 차이가 나타난지 않았으나, 사료 섭취량에서는 고수준의 탄순화물 급여군(HCHO)이 고지방 급여군(딘FAT)에 비해 유의적(P<0.95)으로 증가하였다. 혈중 glucose 함량은 HFAT군에서 다른 군에 비해 유의적으로 증가되었으나,중성지항은 오히려 고탄수왔물 급여군인 HCHO군엑서 증가하는 경향이 뚜렷하였다. 혈장내 insulin 농도는 HFAT군에서 현저한 증가를 보여 insvliu resistauce 현상을 나타내었다. 혈중 leptiBl농고는 MFAT와 HFAT군에서 HCHO와 REST군에 비해 유의적으로 증가하였으며, 특힉 절식군인 REST군에서는 HFAT와 HFAT군들에 비왜 약 3배 이상의 감소치를 보였다. Leptin receptor(extra-cellular와 intracellular donlain)의 mnNA 발현을 조사한 결과 영양소원 및 절식에 따른 영향 즉 혈중 leptin 함량에 따라서 leptin receptor왁 발현은 아문런 차이를 나타내지 않았다. NPY를 시상하부 3곳의 주요 nuclei(arcu-ate, paraventricular, supraopti매에서 면역 염잭하여 관찰한 결과 역시 혈중 leptin 및 insulin 함량파는 상관없이 HC려0, MfAT 및 HFAT군에서 모두 비슷한 양상을 보였다. 그러나 절식군인 REST군에서는 NPY 발현이 감소 하였다. 결론적으로 주에너지원으로 고지방 급여시 비만 및 당뇨가 유발되었으며, 증가된 혈중 leptin 맞 insulin은 41상31부 lertinreceptor 및 NPY조절을 통한 비만 조절 기전에 유의한 영향을 미치지 않았다. Leptin, prodv.cts of the adipose-specific oS gene, acts an important effect in the rrgulation of obesity. Several studies with obesity model animals have suggested that the action of leptin or-erted in the hypothalamus of the brain. However, in contrast to obesity model animals such as oo/oc, dD/08 mice aBd zucker rats,,dietary induced obesity model has not been intensively investigated on leptin'ssignaling pathway. Therefore, six wk old SD rats(n= 90) were allotted to HCHO(high carbohydratediet) group fed the diet couts.ming 70% carbohydrate and 11% fat, Mf'AT (medium fat diet) group frdthe diet containing 48% carbr)hydrate and 32.5% fat, HFAT(high fat diet) group fed the containing 33.3% carbohydrate and 42.8% fat, as basis of energy, and REST(restricted feeding) group that fed 50%restricted amount of ad fiSifHu3 of MFAT diet. All diets except REST consist of the salne energy densityand SB rats tvere continualty fed the purified diets for 13 wks. The body weight was not altered by die-tary treatrnftts eBcept REST group. However, daily feed intake increase4 in HCHO and MFAT grouprcompared with HFAT. Also, feeding HFAT enhanced serum glucose, insulin, and leptin levels when com-pared with IfCHO and REST groups. A second. stage was to determine whether the expressions of leptinreceptor and neuropeptide Y(Iffy ) in the hypothalamos were affected by serum leptin and insulia con-centrations. No difference in leptin receptor mRNA expression by RT-PCR were found amoBg groups. Inaddition, serum leptin and insulin did not alter NPY expression levels in arcuate, paraventricular, andsupraoptic nuclei in the hypothalamus. In summary, the expressions of leptin receptor and NPY arealtered by neither diet, nor leptin and iusulin levels in dietary induced obese SD rats.

In this paper, we presented geometric CAD watermarking scheme for Architectural design drawings using line, arc, and circle components to prevent infringement of copyright from unlawfulness reproductions and distribution. The conventional CAD watermarking scheme can be applied to both line and arc components. But the proposed scheme consists of line, arc and circle watermarking schemes for three basic components of CAD design. After extracting line, arc and circle components from designed drawing, the watermark is embedded into the length of Line component, the angle of arc component, and the radius of circle component considering the robustness against various geometric transformations. The embedding strengths in each component are determined to be preserving the transparency of the watermark. By experimental result, we confirmed the robustness and the invisibility of embedded watermarks in several conversions of architectural design drawing.
