본 논문에서는 UWB Low Band(낮은 주파수, 3.1 ~ 5 GHz) 에 대해 통과특성을 갖는 대역필터 결합형 UWB 안테나를 제안하고자 한다대역필터 결합형 UWB 안테나”를 제작하기 위하여 2004년에 발표된 “사다리꼴 모양의 UWB 안테나“를 3.1 ~ 8 GHz 주파수 대역을 만족하는 UWB 안테나 부분으로 변형 설계 • 제작하였으며, UWB Low Band (낮은 주파수, 3.1 ~ 5 GHz)를 통과시키는 필터 또한 설계 · 제작 하여 대역통과필터로서 제 성능을 분석하였다‘ 최종적으로, 제작한 두 안테나와 필터부분은 Matching Stub 에 의해 결합되고, 30cm 이격거리에서 측정한 그룹 딜레이 변화량은 1 ns 에서 선형특성을 보였으며, 기타 UWB 안테나의 제 특성들도 만족한 결과를 나타냈다. In this paper, 1 arn going to pr때ose a new UWB antenna which combines a filter filtering characteristics for the UWB low band frequencÎes(3.1 ~ 5 GHz). In order to make a "Band pass filter combined UWB antenna", 1 have modified and fabricated "A Trapezoidal Ultra-Wideband Antenna Oesign" that had been presented in 2004 as a part of UWB antenna which is satisfactory with UWB communication band from 3.1 to 8 GHz. The low band UWB filter, filtering band from 3.1 to 5 GHz, have also designed, fabricated, and measured as a BPF. Finally, these two antennas and filter device p따ts of were combined with a matching stub. The measured group delay variation between two devices separated by 30cm was less than 1 ns, and other UWB antenna properties were also satisfactory.
Postgenomics of Tribolium : Targeting the endocrine regulation of diuresis
박윤성,Richard W. BEEMAN 한국곤충학회 2008 Entomological Research Vol.38 No.2
Coleopteran insects comprise a highly successful taxon, representing more than 25% of eukaryotic species, many of which are economically important. One of these, the red flour beetle (Tribolium castaneum H.), is a major pest of stored grain and cereal products and is also an excellent genetic model for the Coleoptera. The Tribolium genome sequencing project was recently completed, the first for anagricultural insect pest species. This genome sequence and annotation, in combination with the tractability of Tribolium for genetic dissection and functional genomic analysis, makes it one of the most useful subjects for studies of insect development, genetics and physiology. Tribolium has a number of interesting physiological adaptations, including desiccation tolerance associated with specialized cryptonephridial organs for active rectal absorption of atmospheric water. The study of endocrine regulation of diuresis in this species has led to the identification of a number of osmoregulatory peptides, including the novel argininevasopressin-like peptide.

Objectives Impaired lung function(ILF) and sasang constitution(SC) is associated with metabolic syndrome(MS). However, the relationship between ILF and SC is unclear. So, we assessed the relationship between ILF and MS according to SC, and examined whether SC is an independent risk factor for ILF. Methods This study included 1,148 subjects 40years and older who were performed the health examination at Kyung Hee University Hospital in Korea between December 2011 and February 2013. We defined ILF if FVC or $FEV_1$ value were less than lower limit of normal(LLN), and classified ventilatory patterns as obstructive pattern and restrictive pattern. MS was assessed according to AHA/NHLBI criteria. We used multivariate logistic regression to analyze the association of ILF with MS respective to SC types, and to identify the risk of SC types for ILF. Odds ratio(OR) was calculated by adjusting for age, sex, smoking status, drinking, physical activity, and BMI. Results In whole subjects, ILF was associated with MS [OR (95% CI), 1.69 (1.24-2.31) for FVC, 1.67 (1.20-2.33) for $FEV_1$]. And in Taeeum type(TE type) and Soeum type(SE type), ILF was associated with MS [1.63 (1.10-2.42) for FVC, 1.48 (1.01-2.24) for $FEV_1$ in TE type; 6.93 (1.14-42.00) for FVC in SE type], while in Soyang type(SY type), it wasn't. The restrictive pattern was associated with MS in TE type and SE type, while in SY type, it wasn't. Furthermore, TE type and SY type had more risk for ILF than SE type [1.71 (1.12-2.59) for SY type, 1.95 (1.23-3.08) for TE type in FVC; 2.06 (1.26-3.36) for TE type in $FEV_1$; 1.85 (1.21-2.85) for SY type, 2.17 (1.35-3.49) for TE type in Restrictive pattern]. Conclusions These results show that SC is an independent risk factor for ILF, especially TE type and SY type than SE type, and the prevalence of MS is an independent risk factor for ILF in TE type.
