As the designated name, adenocarcinoma, not otherwise specific (ANOS) revealed lack of histomorphologic characteristics that could classify the tumors under specific name. ANOS had nothing in common with other salivary gland malignancies, but glandular differentiation. The purpose of this study is to find out the solid characteristics of ANOS on the base of cytological and architectural features. 20 ANOS cases were studied. We identified 20 patients with salivary adenocarcinoma, not otherwise specified, ranging in age from 26 to 76 years (median, 53.85 years), with slight female predilection (female 11: male 9). The minor salivary gland was the most common site of tumor origin, especially on the palatal area (11 out of 20). The size of tumor was from 1.0 to 7.0(median 3.07). For the histopathological analysis, we classified the tumors by cytological and architecture patterns. Basaloid and epitheloid cytological patterns were showed with solid, microcystic/pseudocystic architecture. We found invasive growth patterns in 7 out of 20 cases. Reviewing and classifying the common features of ANOS could be helpful to make a diagnosis of malignant salivary gland tumors.

Morphological properties of dark banded rockfish (Sebastes inermis) were analysed to investigate its acoustic scattering characteristics. Total of 18 live samples was prepared for X-ray photos and collected morphological coordinates of their body and swim bladder shapes. Kirchhoff-ray mode model was used to calculate acoustic scattering pattern for broad-band frequency range. Inclination of swim bladder ranged from 17 to 30 and the averaged value was about 25.2° (S.D.(standard deviation)=3.15). There were no any tendency of increase or decrease in volume and area ratio of swim bladder to fish body and ranged from 2.2 % to 4.43 % and 14.85 % to 21.31 %, respectively. The averaged value of volume and area ratio was 3.13 % (S.D.=0.52) and 17.6 % (S.D.=1.5). b20 values were –69.01 for 38 kHz, –69.83 for 70 kHz, –70.17 for 120 kHz and -70.93 for 200 kHz, recpectively. Broadband acoustic patterns of dark banded rockfish for 20 ~ 200 kHz were similar among samples and they reflected size and morphological properties of fish species.

PDA배지에서 25℃로 배양할 때 초기 균사의 색은 흰색을 띄고 있었으며 배양 후기에 생성되는 포자의 색은 짙은 푸른색을 나타내고 있었다. 시간당 성장률은 1.1mm보다 빠른 것으로 나타났으며 성숙한 포자의 모양은 부드럽고 구형에 가까운 모양이었다. 이러한 형태학적 결과는 시간당 성장률이 0.5-0.7mm 이하인 Tricho-derma viride 및 T. hamatum의 특징과 성숙 포자의 모양이 실린더 모양인 T. koningii,

Seventy Pipistrellus abramus samples were caught to analyze their sexual dimorphism and mophological characteristics. The mean HB and FA were 50.86 mm and 34.93 mm, respectively, based on external measurements and skull shape. The length of the TL, Hfcu, and Tra were approximately 70%, 55.6%, and 38% of the HB, Tib, and E, respectively. Both the lambdoid crest and the sagittal crest were well developed and the H.BC was approximately 84% of the W.BC. P2 was inside the toothrow and metacone of canine was clearly visible. According to the analysis of sexual dimorphism, the following characteristics were different in between males and females: WS, C-M3, C-C, M3-M3, LOM, LUC, and i-m3. The WS, C-M3, C-C, M3-M3, LOM, and i-m3 were bigger in females than males, whereas the LUC was bigger in males.

In this paper, we proposed a new algorithm of the guidance line extraction for autonomous weeding robot based on infrared vision sensor in wet paddy. It is the critical process for guidance line extraction which finds the central point or area of rice row. In order to improve accuracy of the guidance line, we are trying to use the morphological characteristics of rice that the direction of rice leaves have convergence to central area of rice row. Using Hough transform, we were represented the curved leaves as a combination of segmented straight lines on binary image that has been skeletonized and segmented object. A slope of the guidance line was gotten as calculate the average slope of all segmented lines. An initial point of the guidance line was determined that is the maximum pixel value of the accumulated white columns of a binary image which is rotated the slope of guidance line in the opposite direction. We also have verified an accuracy of the proposed algorithm by experiments in the real wet paddy.

당귀류 약재의 기원식물에 대해 해부형태적 특징을 관찰하고, 이를 통하여 당귀 기원 및 국내유통 당귀류 약재의 판별에 이용코자 실험한 결과는 다음과 같다. 기원식물 뿌리의 해부형태특징은 정상 2기생장, 주피발달, 유세포내 전분함유 등이 공통점이었고, 후각세포층은 참당귀와 왜당귀에서 관찰되었으며 피층의 유실분포는 참당귀와 중국당귀에서 관찰되었다. 또한 참당귀에서만 속성후벽세포가 다량 관찰되었다. 잎의 표피세포는 중국당귀가 가장 컸으며 세포표면의 형태는 참당귀와 중국당귀는 거친 주름이져 있었고, 왜당귀는 완만한 굴곡이 관찰되었다. 3종의 기공은 모두 불규칙형 부세포를 가지고 있었고 참당귀가 mm2당 600개 이상으로 가장 많은 기공이 분포하고 있었다. 모용은 참당귀에서만 원뿔형으로 관찰되었다. 엽병은 3종식물에서 모두 유조직이 잘 발달된 형태였고 환상으로 병립유관속이 발달하고 있었다. 국내 유통 당귀류 약재의 판별에 있어서 해부형태적 특징을 정리하여 간단한 동정 KEY를 적용하여 만든 검색표가 유용하게 활용될 수 있었다. 검색표를 이용하여 전국 7개 지점에서 수집한 약재를 판별한 결과, 당귀 (국산) 또는 토당귀로 유통되는 약재는 참당귀 (A. gigas)로 동정되었고, 일당귀로 유통되는 약재는 왜당귀(A. acutiloba)로 동정되었다. 중국당귀는 현재 시중 유통되지 않고 있으며 본연구에서 사용된 약재 중국당귀는 중국 현지에서 직접 구입해 온 것으로 중국당귀 (A. sinensis)의 뿌리와 동일한 횡단면 형태를 관찰할 수 있었다. 그러므로, 현재 국내 유통되는 당귀류 약재는 (토)당귀의 경우는 KP에서 규정하는 것과 동일기원이었으며, 일당귀는 일본약국방(JP,2001)에서 규정하는 것과 동일한 기원으로 당귀류 유통약재의 기원상에 오류는 없었다.
