볼록총채벌레는 최근 감귤원 해충 피해의 주요 해충으로 인식되어 주기적인 예찰이 이루어지고 있으나 성충의 크기가 0.8㎜ 정도로 작아 육안 식별에 어려움이 있다. 본 논문에서는 예찰 트랩에 포집된 볼록총채벌레를 자동으로 판별하기 위한 후보 영역 검출 방법을 제안하였다. 본 논문에서 사용한 방법은 히스토그램 기반의 템플릿 매칭으로 그레이 이미지와 그레디언트 이미지를 합성한 이미지를 사용하였다. 50 배율의 광학 현미경으로 영상을 획득 하였고, 제안한 방법의 객관적인 성능 판별을 위해 기존 방법[8]과 노이즈 제거 이미지를 이용한 히스토그램기반 템플릿 매칭방법 그리고 그게디언트 이미지를 이용한 히스토그램 기반 템플릿 매칭 방법들과 비교 실험을 하였다. 실험결과 본 논문에서 제안한 방법이 기존 전처리[8] 방법 보다 약 14.42% 향상된 성능을 보였고, 노이즈 제거 이미지를 이용한 방법보다 41.63%, 그레디언트 이미지를 이용한 방법보다 21.17% 높은 성능을 보였다. Scirtothrips Dorsalis (Thysanoptera: Thripidae) recently has been recognized as a major source of the pest damage in the citrus fruit orchards. So its arrival has been predicted periodically but it is difficult to identify adults of the pest with the naked eyes because of their size smaller than the 0.8㎜. In this paper, we propose a method to detect candidate areas for automatic identification of Scirtothrips Dorsalis on forecasting traps. The proposed method uses a histogram-based template matching where the composite image synthesized with the gray-scale image and the gradient image is used. In our experiments, images are acquired by the optical microscopy with 50 magnifications. To show the usefulness of the proposed method, it is compared with the method we previously suggested. Also, the performances when the proposed method is applied to noise-reduced images and gradient images are examined. The experimental results show that the proposed method is approximately 14.42% better than our previous method, 41.63% higher than the case that the noise-reduce image is used, and 21.17% higher than the case that the gradient image is used.

PPAR‐gamma modulates allergic inflammation through up‐regulation of PTEN

Lee, Kyung S.,Park, Seoung J.,Hwang, Pyoung H.,Yi, Ho K.,Song, Chang H.,Chai, Ok H.,Kim, Jong‐,Suk,Lee, Moon K.,Lee, Yong C. Federation of American Society for Experimental Bi 2005 The FASEB Journal Vol.19 No.8

<P>The ligand-activated nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) has been shown to regulate cell activation, differentiation, proliferation, and/or apoptosis. PPARgamma is also associated with anti-inflammatory responses. However, the signaling mechanism remains elusive. We have used a mouse model for asthma to determine the effect of PPARgamma agonists, rosiglitazone or pioglitazone, and PPARgamma on allergen-induced bronchial inflammation and airway hyperresponsiveness. Administration of PPARgamma agonists or adenovirus carrying PPARgamma cDNA (AdPPARgamma) reduced bronchial inflammation and airway hyperresponsiveness. Expression of PPARgamma was increased by ovalbumin (OVA) inhalation, and the increase was further enhanced by the administration of the PPARgamma agonists or AdPPARgamma. Levels of IL-4, IL-5, IL-13, and eosinophil cationic protein were increased after OVA inhalation, and the increased levels were significantly reduced by the administration of PPARgamma agonists or AdPPARgamma. The results also showed that the administration of PPARgamma agonists or AdPPARgamma up-regulated phosphatase and tensin homologue deleted on chromosome ten (PTEN) expression in allergen-induced asthmatic lungs. This up-regulation correlated with decreased phosphatidylinositol 3-kinase activity as measured by reduced phosphorylation of Akt. These findings demonstrate a protective role of PPARgamma in the pathogenesis of the asthma phenotype through regulation of PTEN expression.</P>

Al-Doping Effect on the Photoluminescence Behaviors of CaTiO3:Pr3+ Powder Phosphors

Yang HyunKyoung,Jeong Jung Hyun,Kim Jung Hwan,Kim Pyoung,Moon Byung kee,Yi Soung Soo 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.49 No.1

The correlation between the crystallization, the surface morphology, and the luminescent properties of Al-doped CaTiO3:Pr3+ powder phosphors has been investigated. Al doping in the host lattice improves the crystallization and enhances the luminescent properties. The grains of Al-doped CaTiO3:Pr3+ powder were larger and well-defined with orthorhombic shapes compared with those of a CaTiO3:Pr3+ powder. According to the cathodoluminescence(CL) and photoluminescence(PL) results, the red emission peaks from the 1D2!3H4 transition were increased by more than about 1.5 and 1.8 times with Al-doping. The red emission peaks at 610, 612, 614, 626, and 637 nm are assigned to 4f-5d transitions from the 1D2 states to the ground state. As the temperature was increased from 12 to 300 K, the shape of PL spectra remained the same, and the PL intensity uniformly increased for both the CaTiO3:Pr3+ and the Al-doped CaTiO3:Pr3+ powders. The PL intensity was increased by more than 3 times with Al-doping. For the CL spectra, Al-doped CaTiO3:Pr3+ was stable, and no change in crystal field was seen under a low acceleration voltage.P

Kinetic Studies on the Reaction of Thiocyanate with Di-$\mu$-oxobis-(aquaoxalatooxomolybdate (V)) in Acid Media

산성용매에서 몰리브덴-옥살산 결합의 고리열림이 일어난 다음 티오시안산과 반응하는 속도를 460nm에서 분광학적으로 측정하였다. 산성용매에서 몰리브덴-옥살산의 해리와 이 해리된 착물과 티오시안산의 반응속도를 티오시안산 및 수소이온농도에 따라 연구하였다. 몰티브덴에 결합된 옥살산리간드에 양성자첨가가 되고 이 양성자 첨가된 착물은 티오시안산이온과 반응을 빠르게 한다. 이들 결과에서부터 산성용매에서 옥살산리간드의 치환은 몰리브덴닐산소의 트란스에 결합된 산소의 결합이 끊어지는 과정과 관련되는 해리메카니즘에 의해서 설명할 수 있다. Rate constants for complexing with thiocyanate after ring opening of molybdenum-oxalate in acid media were obtained spectrophotometrically at 460nm. The acid-assisted dissociation of molybdenum-oxalate and the reaction of thiocyanate with oxalatooxomolybdenum (V) complex in acid media were investigated with thiocyanate and hydrogen ion concentration. The kinetic data indicate that molybdenum-oxalate is protonated to a limited extent in acid media and the protonated complex is responsible for an increase in rate for the reaction of thiocyanate with oxalatooxomolybdenum (V) complex. Replacement of an oxalate ligand in acid media has been interpreted in terms of dissociative mechanism involving bond-breaking of the oxygen trans to the yl oxygen.

Color of $MoO_{(aq)}^{3+}$ in concentrated methanesulfonic acid (∼10M) changes dark green due to the formation of $Mo_2O_2(OH)_{2(aq)}^{4+}$ dimer. This color is similar to that shown by addition of water to that shown by addition of water to green $MoO_{(aq)}^{3+}$ solution in 15-16M methanesulfonic acid. The molar extinction coefficient of monomer in 15M methanesulfonic acid is about 20 at 415nm. Rate constants are independent on the aquomolybdenum (V) and hydrogen ion concentration under the condition of this experment. Bridging hydroxides of $Mo_2O_2(OH)_{2(aq)}^{4+}$ are dehydrogenated at the less concentration of ∼6 M for HPTS and ∼10M for $CH_3SO_3H$. The structure of both the yl-oxygens and the bridging oxygens of final product is identified to (*image)unit. 진한 메탄설폰산(약10M)에서 초록색의 $MoO_{(aq)}^{3+}$는 진한 초록색의 이합체인$Mo_2O_2(OH)_{2(aq)}^{4+}$를 생성한다. 또한 이러한 진한 초록색은 15-16M의 메탄설폰산에서 존재하는 $MoO_{(aq)}^{3+}$용액에 물을 가하면 나타나며 15M의 메탄설폰산에서 단위체의 몰흡광계수는 415nm에서 약 20이다. 속도 상수는 이 실험조건하에서 아쿠오몰리브덴(V)와 수소이온농도에 의존하지 않는다. $Mo_2O_2(OH)_{2(aq)}^{4+}$의 수산화이온은 HPTS 약 6M, $CH_3SO_3H$는 10M이하에서 탈수소화반응이 일어난다. 마지막 생성물의 말단산소와 다리산소의 구조는 (*image) 단위를 가진 것으로 확인되었다.
