본 연구에서는 수동소나 신호의 분석에서 얻어지는 토널 성분, 즉, 주파수선의 하모닉 성분을 강화하는 새로운 방법을 제안하였다. 제안한 방법에서는, 먼저 스펙트럼의 일정 시간에 따른 주파수 빈별 평균값을 구하고, 평균값과의 차이를 이용하여 안정적인 주파수선과 불안정한 주파수선을 구별한다. 그런 다음 불안정한 주파수선에 자기상관함수와 S2PM을 적용하여 배경잡음을 줄이고 하모닉 성분을 강조하게 된다. 실제 어선에서 획득한 수중음향 데이터를 이용한 실험 결과를 분석하였고, 이를 통해 제안한 방법의 타당성을... -

concluded that this method is swift and accurate. Subsequent development of enterobacterial repetitive intergenic consensus PCR has supplemented the Page serovar classification method, but this analysis may not be straightforward [25]. Recent reports have utilized multiplex PCR and PCR restriction fragment length polymorphism as a serotyping method for Page serovars A, B, and C by targeting... Infectious coryza (IC) is an infectious disease caused by Avibacterium (Av.) paragallinarum. IC is known to cause economic losses in the poultry industry via decreased egg production in layers. Between 2012 and 2013, Av. paragallinarum was isolated from seven chicken farms by Chungbuk National University. We identified Av. paragallinarum, the causative pathogen of IC by polymerase chain reaction (PCR) and serovar serotype A, by multiplex PCR. Antibiotic sensitivity tests indicated that a few... -

400× magnification) using computer-assisted image analysis (Jiangsu Jieda 801 series morphologic analysis system, China). By selecting “dot-chosen target” in the option bar of the morphologic analysis system, positive and negative lymphocytes were first marked one by one in red or green, respectively. Next, “disconnect” in the option bar was selected to separate the overlapped cells.... to decrease from E24 to P200. Apoptotic bodies in macrophages, free apoptotic bodies, or nuclei with condensed chromatin in lymphocytes in follicles were identified by transferase-mediated dUTP nick-end labeling. Both flow cytometry and microscopic analysis reveal that the proportion of apoptotic cells and apoptotic lymphocyte density increased from E24 to P20, fell on P70, then rose again on P200. Our foundings demonstrate that cell proliferation decreases and apoptosis increases with age. The... -

measurement by necropsy To measure the actual dimensions of the kidneys, twenty- seven of 50 cats were necropsied after ultrasonographic examination. Both kidneys were removed and measured using Vernier calipers (Mitutoyo, Japan). Data analysis The correlation coefficiency for the group means for body weight and renal dimension were calculated and compared using statistical software packages... Renal length, height, width, resistive index (RI), size of cortex, and medulla were determined by renal ultrasonography in 50 healthy Korean domestic short-hair cats. In the sagittal plane, the renal length was 3.83 ± 0.51 cm (mean ± SD) in the left kidney and 3.96 ± 0.48 cm in the right kidney, whereas the renal height was 2.42 ± 0.27 cm in the left kidney and 2.36 ± 0.28 cm in the right kidney. In the transverse plane, the renal height was 2.42 ± 0.28 cm in the... -

antibody conjugated to HRP (Santa Cruz, USA) in T-TBS buffer for 1 h. After washing, the bands-of-interest were pictured by luminescent image analyzer LAS-3000 (Fujifilm, Japan). Statistical analysis The results were expressed as mean ± SD values for independent experiments. Statistical analysis was performed on all groups using the t test. Results Clinical hematology and biochemistry In the... Interferon (IFN) has therapeutic potential for a wide range of infectious and proliferative disorders. However, the half-life of IFN is too short to have a stable therapeutic effect. To overcome this problem, serum immunoglobulin has been fused to IFN. In this study, the efficacy of serum immunoglobulin fused INFs (si-IFN1 and si-IFN2) was evaluated on athymic mice bearing colon 26 adenocarcinoma cells. Seven days after the implantation of tumor cells, each group of mice was injected once a week... -

Pregnant ICR mice were exposed on day 11.5 after conception, coincident with the most sensitive stage for the induction of major congenital malformations, with 0.5-4.0 Gy of gamma- radiations. The animals were sacrificed on day 18 of gestation and the fetuses were examined for mortality, growth retardation, change in head size and any other morphological abnormalities.... -

The objective of this investigation was to evaluate the influence of gestational age at exposure on the prenatal effects of gamma-radiation. Pregnant ICR mice were exposed to a single dose of 2.0 Gy gamma-radiation at a gestational 2.5 to 15.5 days post-coitus (p.c.). The animals were sacrificed on day 18 of gestation and the fetuses were examined for mortality, growth retardation, change in head size and any other morphological abnormalities.

Statistical analysis Testosterone and progesterone concentrations and the GnRH antibody titer were analyzed using the general linear model (two-way repeated measurement in ANOVA), and compared between the groups using the one-way ANOVA. Testes size and back fat thickness were analyzed using the paired-samples t-test. The Chi-squared test was used to ana- lyze the sensory evaluation. The... -

Results All radii had only a single NF, and the majority of humeri and ulnae (94.7% in both) also had one NF. Five humeri and five ulnae had two NFs (Table 1); the diameter of the proxi- mal NF was larger than that of the distal NF in the humerus but...
