Recently, our construction industry is using various work sections classification systems for civil engineering projects. However, because the public IDB(Integrated DataBase) for the work sections is insufficiently built, it is difficult to connect construction operation information from construction site to standard specification or standard method of measurment. Therefore, this study suggests a methodology to link the construction work sections information, such as cost, schedule, drawings and specification, with civil engineering standard method of measurement. And the methodology suggested in this study was applied to a web-based work sections information management system with IDB. An IDB modeling was designed by using DFD (Data Flow Diagram) and ERD (Entity Relationship Diagram).

We proposed correlation exponent as feature vector of speaker recognition system aming the persons whose voices are much the same with each other. The ambiguity of speech utterance can be regarded as a chaotic property. For speakers whose voices appear to be nearly identical, with their vowel /i/ that is more chaotic than /a/,/e/,/o/, or /u/ was tested. since chaos which is sensitive to a noise, a reduction is necessary. We eliminate the noise by local projective noise reduction method and compare the behavior of the attractors of original speech and noise reduced speech. 본 논문에서는 발음이 매우 유사한 사람들 간의 화자 인식 시스템 구현을 위한 feature vector로써 correlation exponent의 사용을 제안하였다. 음성의 발성적 모호함을 chaos적인 특성으로 간주하고 formant 특성이 거의 동일하게 나타나는 화자들에 대해 모음 /i/ 발음을 채집하였다. 잡음에 민감한 카오스의 correlation exponent를 구하기 위해서는 선행적으로 잡음제거가 필수적이다. 이를 위해서 비선형 방법으로 잡음을 제거하고 잡음제거전의 각 화자들의 attractor를 비교하였다.

In the upper gastrointestinal tract, in particular, there are parts consisting of esophageal sphincter muscles to carry out physiologic functions, which causes impairments when removed, as well as such complications as mucosal injuries, bleeding and even perforations in the case of foreign bodies with large size and/or sharp angles. Therefore, it is essential to use an appropriate type of supplementary instrument for a safe procedure. Frequently utilized supplementary instruments are overtube, protector hood, latex glove and transparent cap. We report a case in which authors were successful in removing a watch bend consisting of metal ring from gastric body while using a modification of a widely available drip chamber of fluid set attached to vertical end of endoscopic device.

AML is the most common type of leukemia in adults. AML(acute myeloid leukaemia) is characterised by a rapid accumulation of abnormal white blood cells in the blood and bone marrow, resulting in severe anemia, and possibly infection, and hemorrhage during the course of the disease. In general the prognosis of patient with relapsed AML is poor. At this time, however, the only potentially curative therapy for relapsed patients is allogeneic BMT(bone marrow transplantation). This clinical study were carried out 1 case of female patient aged 44 with relapsed AML treated by herb medicine. At the time of admission, she complained of mild fever, nausea, vomitting, abdominal pain, anorexia and no sign of bleeding. For the 10 days of admission, she was treated with Oriental-Western medicine and all the symptoms were disappeared. After that, the syptoms were aggravated because of secondary infection. Anyway, above result showed the possibility of Oriental therapy as Supportive Care in AML.

What is the most important in articles of food is hygienic safety. Because food is the most common thing in our everyday life, however, the importance of its hygienic safety and other many problems caused by food may be easily neglected. Since PL Law came into effect in July of the last year(2002) in Korea, many domestic firms have taken great interests in PL. And the purpose of PL Law is to provide a means for those injured by defective products to receive redress. Additionally, enterprises get to place more importance on the safety of the products, which led to improvement in competitiveness and enhancement in quality. Consequently customers can get better products. So, it aims not only to compensate the injured by defective products but also to act an incentive to makers/suppliers of food to make their products more safe. Therefore, this study was aiming to analyze the expected risks to articles of food after the enforcement of PL Law, and to establish a defending plan.

Si(111)기판 상에 Au층을 통한 GexSi1-x 화합물 반도체의 고체상 에피탁시

Si(111) 기판 위에 Au와 Ge을 차례로 약 1000Å 증착하여 a-Ge/Au/Si(111) 구조를 준비한 후 이를 고진공 조건에서 열처리하는 고체상 에피탁시법(solid phase epitaxy : SPE)으로 Ge□Si1-□ /Si(111) 이종 접합을 형성하였다. Auger 전자분광분석(AES), x-ray 회절(XRD), □HE□ 이온 후방산란 분광법(RBS), 고분해 투과전자현미경(HRTEM) 등을 이용하여 Ge 및 Au의 거동과 형성된 Ge□Si1-□ /Si(111)의 결정성을 조사하였다. 400℃에서 열처리 한 시료에서 균일한 Ge□□□Si□□□상이 형성되었고, 440℃에서 열처리 했을 때는 Ge□□□Si□□□와 Ge□□□Si□□□가 혼합된 상들이 동시에 관찰 되었으며, 470℃이상에서 열처리 한 시료는Ge□□□Si□□□의 단일상만 관찰되었다. 단면 TEM 사진으로부터 Ge□Si1-□ /Si(111) 계면에서의 에피탁시는 비교적 잘되었으나, 쌍정, 전이, planar defect 등이 (111)면을 따라 형성되고 있음이 확인되었다. For the formation of GexSi1-□ /Si(111) heterostructure by solid phase epitaxy (SPE), Au and Ge layers with about 1000Åthickness were sequentially deposited on the Si(111) substrate, then the resulting Ge(1000Å)/Au(1000Å)/Si(111) samples were annealed in the high vacuum condition. The behaviors of Au and Ge during thermal annealing and the structural properties of Ge□Si1-□ films were characterized by Auger electron spectroscopy (AES), X-ray diffraction (XRD), □HE□ ion backscattering spectrometry (RBS) , and high resolution transmission electron microscopy (TEM). A uniform Ge□□□Si□□□ phase was observed from the sample annealed at 400℃, but mixed Ge□□□Si□□□and Ge□□□Si□□□ phases were observed at 440℃. And Single Ge□□□Si□□□ phase was identified from samples annealed over 470℃. At GexSi1-x /Si(111) interface the epitaxy was relatively performed well, but defects such as stacking faults, twin band, point defects, and dislocations were found by TEM cross section pictures

This experimental study was carried out to evaluate the effects of Cordiceps sinensis on the antimetastasis and immune activity. In order to investigate the effect of Cordiceps sinensis, the followings were performed; Cytotoxicity, inhibition of MMP-2 & MMP-9 gene expression, fraction of CD4+, CD8+, CD19+ in splenic cell, the moprphological change of splenic cells, gene expression of IL-12(p35), IL-12(p40), IFN-?? and splenic cell proliferation by CS-E. The results were obtained as follows. 1. CS-E did not present cytotoxic effect on L+14, B16-F10 melanoma cells and HMCB. 2. CS-E inhibited MMP-2 and MMP-9 gene expression more effectively compared with control group. 3. CS-E inhibited invasion of B16-F10 melanoma cells more effectively compared with control group. 4. CS-E helped CD4+, CD8+, CD19+ expression more effectively compared with control group. 5. CS-E activated phagocytic cells in spleen more effectively compared with control group. 6. CS-E helped IL-12(p35), IL-12(p40), IFN-?? gene expression in splenic cell more effectively compared with control group. 7. CS-E activated splenic cell proliferation more effectively compared with control group. From above findings, it is suggested that CS-E is able to inhibit metastasis of cancer and activate immune response system.

Analysis of IL-12 and IFN-γ attached by stomach cancer, increasing of IL-12(39.1%), IFN-γ(69.6%) were observed. 6. Analysis of QOL attached by stomach cancer, maintenance and improvement of combined treatment of western and oriental therapy(91%), traditional oriental therapy(85.2%) were observed. 7. Analysis of survival in patients with Ⅳ stage of stomach cancer, above 6 months(17.1%), 12 months(85.2%) were observed. 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(81.5%) and maintenance and improvement of combined treatment of western and oriental therapy(89.7%) were observed. Analysis of tumor marker attached by stomach cancer, maintenance of CEA(85.7%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(77.7%), combined treatment of western and oriental therapy(82.1%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for stomach cancer patients by combination with western therapy or alone.
