The genetics of the prion protein gene (PRNP) play a crucial role in determining the relative susceptibility to transmissible spongiform encephalopathies (TSEs) in several mammalian species. To determine the PRNP gene variability in European red deer (Cervus elaphus), roe deer (Capreolus capreolus) and chamois (Rupicapra rupicapra), the PRNP open reading frame from 715 samples was analysed to reveal a total of ten single nucleotide polymorphisms (SNPs). In red deer, SNPs were found in codons 15, 21, 59, 78, 79, 98, 136, 168 and 226. These polymorphisms give rise to 12 haplotypes, and one of which is identical to the PRNP of American wapiti (Rocky Mountain elk, Cervus elaphus nelsoni). One silent mutation at codon 119 was detected in chamois and no SNPs were found in roe deer. This analysis confirmed that European wild ruminants have a PRNP genetic background that is compatible with TSE susceptibility, including chronic wasting disease.
CORE AND GLOBAL PROPERTIES OF EARLY-TYPE GALAXIES AND THEIR GLOBULAR CLUSTER SYSTEMS
Cote, Patrick,The Acs Virgo And Fornax Cluster Survey Teams, The Acs Virgo And Fornax Cluster Survey Teams The Korean Astronomical Society 2010 天文學論叢 Vol.25 No.3
The core and global properties of the early-type ("red sequence") galaxies in the Virgo and Fornax clusters are examined using high-quality HST/ACS imaging for 143 galaxies. Rather than dividing neatly into disparate populations having distinct formation and/or evolution histories, many of the core and global properties of these galaxies show smooth and systematic variations along the galaxy luminosity function. The few examples of the rare class of compact elliptical galaxies in our sample all show properties that are strongly suggestive of tidal stripping by massive galaxies; if so, then these systems should not be viewed as populating the low-luminosity extension of so-called "normal" elliptical sequences. These results demonstrate that complete and/or unbiased samples are a pre-requisite for identifying the physical mechanisms that gave rise to the early-type galaxies we observe locally, and how these mechanisms varied with mass and environment.
Design and Verification of a Miniaturized Multifunctional Transmitarray Unit Cell for the S-Band
kgd0406@pusan.ac.kr,Hwang, Myeongha,LEE, InGon,Kim, Sangkil 한국전자파학회 2023 Journal of Electromagnetic Engineering and Science Vol.23 No.6
In this paper, a miniaturized multifunctional unit cell structure of a transmitarray operating at S-band and its verification method using a waveguide structure is presented. The unit cell of a multifunctional transmitarray antenna is a critical component because it controls the phase and polarization of an incident wave. The proposed unit cell consists of three main parts: an Rx antenna, a Tx antenna, and a control circuit for phase and polarization. The performance of the designed unit cell is verified by a rectangular waveguide structure. The waveguide structure feeds an electromagnetic wave propagating in a TE10 mode to a 1 × 2 unit cell array to verify polarization and phase shifting capability of the unit cell. The phase shifting and polarization conversion capabilities of the proposed unit cell are directly measured by the radiation patterns and polarization of the transmitted wave.

Permutation p-values are provided for the agreement measures for multivariate interval data among many raters. Three agreement measures, Berry and Mielke’s measure, Janson and Olsson’s measure, and Um’s measure are described and compared. Exact and resampling permutation methods are utilized to compute p-values and empirical quantile limits for three measures. Comparisons of p-values demonstrate that resampling permutation methods provide close approximations to exact p-values, and Berry and Mielke’s measure and Um’s measure show similar performance in terms of measuring agreement.

The circular CAV damper has been developed based on examining the pressure loss and the rotating moment of the damper. If a torsional spring is attached to the damper axle and the equilibrium opening angle where the spring is unstretched, is adjusted at about 80 open, the volume rate through the damper is almost independent of the applied pressure.

Acute appendicitis is a common occurrence in childhood. It is very rare in newborns, so it misses the appropriate diagnosis time. Peritonitis due to perforation of acute appendicitis is the cause of death. We report the case of periappendiceal abscess of female premature baby on the age of 23 weeks and 3 days. The baby has abdominal distension and irritability, and she did not respond to antibiotics and conservative treatment. No abnormal findings were found on simple plain radiography and ultrasonography on the abdomen. The clinical manifestations did not improve in spite of conservative care - antibiotics, nasogastric decompression. So diagnostic laparotomy was done. On operation, panperitonitis was found which may be caused by periappendiceal abscess. After ileocecectomy the patient was recovered and gained weight to 2,050 gram. Appendicitis should be considered in the differential diagnosis for a neonate with abdominal distension and bilious vomiting and needs strong clinical suspicion.

e-Book은 종이책에서 볼 수 없는 하이퍼링크, 멀티미디어 기능, 쌍방향성 등 여러 장점들을 가지고 있기 때문에, 사용자들이 손쉽게 터치 방식으로 시스템에 접근할 수 있다. XML은 하이퍼링크와 스타일 기능과 지식 전달과 표현에 적합한 구조를 가지고 있기 때문에, XML은 e-Book의 문서표준안으로 제정되었다. 본 논문에서는 서울 1000년 타임캡슐 문화 콘텐츠를 관광객들에게 홍보 및 안내할 수 있는 e-Book 형태로 개발하였다. 또한, e-Book 솔루션을 사용하여 발생된 XML코드의 수정과정을 거쳐 사용자 중심의 e-Book 기반 타임캡슐 안내시스템을 구축하였다. Since e-Book has various advantages of hyper-link, multimedia function, dual-direction, etc, users can access to the system easily by touch method. XML has been established as the document standard of e-Book. For XML has hyperlink, style function, and structure it is suitable for knowledge delivery and expression. In this paper, we developed the Seoul’s 1000 years time-capsule cultural contents into e-Book forms that can guide tourists. We also implemented the time capsule guidance system based on the e-Book of the user center through the modification process of the generated XML code using the e-Book solution.
