This study was carried out to investigate the protective effect of Red Ginseng Saponins on 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induced toxicities in guinea pigs ($200{\pm}10$ g). Normal control (NC) group guinea pigs ($200{\pm}10$ g) received vehicle and saline, while the TCDD-treated (TT) group was given water-extract (WE), saponin fraction (SF) and non-saponin fraction (NSF). Korean red ginseng fractions were administered from 1 week before TCDD-exposure for 4 weeks. Body weight loss and deteriorated clinical parameters related to sugar metabolism and liver function such as lipase and AST, respectively, these were significantly reduced by both saponin and non-saponin fractions. However, increase of lipase was attenuated by the saponin fraction in a dose-dependent manner. Only AST was affected by the saponin fraction. The results suggest that saponins are active substances in the Korean red ginseng water extract against TCDD induced toxicities in Guinea pigs.

이제 HACCP가 무엇이며 왜 이것을 단체 급식소에 적용해야 할 것인가의 것은 더 이상 논의 과제가 아니다. 문제는 어떻게 HACCP 원리를 주방 동선 구성에 적용할 것이며 동시에 이 원리 기준에 적합한 주방 기계 선정 및 운영 절차는 무엇인가에 관한 하드웨어적 접근에 관심이 모여지고 있다. 작은 정부를 주장하는 메리랜드 주에서는 미국에서 최초로 새로운 조리 시설을 짓거나 전반적 보수공사 하는 모든 외식업체는 HACCP Plan을 제출한 후 통과된 경우에 한하여 공사 허가서를 내어주고 있다. 이로써 업체 종사원 스스로가 위생 상태를 점검 기록함으로 함으로 식중독 사고를 사전에 예방함과 동시에 공무원의 업체 방문을 최소화 하여 적은 인원으로 효율적인 주 정부 운영을 하고 있는 것이다. 또한 자발적으로 많은 외식 업체들이 마케팅 차원에서 경쟁 업체와의 차별화 정책의 일환으로 스스로 서둘러 HACCP를 도입하고 있다. 워싱턴 DC지역에서는 요식협회 스스로 HACCP를 도입한 외식업소에 "Extra Step"이라는 로고를 사용케 하고 있다. 이로써 보다 많은 고객들이 이 로고를 보고 해당 식당을 선택토록 광고의 효과를 더 하기 위함이다. 당연히 이와 같은 추세에 따라 유럽과 미국의 세계적인 주방 기기 메이커들도 미국의 National Sanitation Foundation(NSF), US Dept of Agriculture(USDA) 및 FDA 의 규제 흐름에 따라 상당히 빠른 속도로 HACCP 원리에 적합한 기능을 기계적으로 보완해 가고 있다. 최근 4/15/98, FDA가 대량 급식소를 포함한 주방의 HACCP 적용매뉴얼을 인터넷 web 주소 http://vm.cfsan.fda.gov/~dms/ hret-1.htm 통하여 발표한 내용과 미 육군의 식당 위생 기술 자료 TB MED 530 자료, 그리고 87년 12월 이후 (주)HRS 에서 기계 설치 사후 관리하면서 경험한 사항을 중심으로 다음 내용을 정리해 보고자 한다.리해 보고자 한다.

The government is establishing a national governance system so that research data can be systematically preserved and reused as a national asset. Recently, as DMP submission has become mandatory in some research institutes, it is a reality that DMP preparation is becoming a necessity for researchers. Therefore, the purpose of this study is to develop a template so that the researcher can easily write the DMP that must be submitted when planning the project. To develop such a DMP template, 27 domestic and foreign DMP templates were investigated and analyzed, and as a result, a DMP template for domestic researchers was proposed. It is judged that the DMP template proposed as a result of this study can be used as an exemplary case that can be used in other research institutes and universities.

Perfusion magnetic resonance imaging (pMRI) is a special technique for evaluation of blood flow. Exogenous pMRI methods which are dynamic susceptibility contrast (DSC) and dynamic contrast-enhanced (DCE) use an intravenous bolus injection of paramagnetic contrast agent. In contrast, an endogenous pMRM method which is arterial spin labeling (ASL) use diffusible blood in body. In order to scan pMRI in human, technical optimizations are very important according to disease conditions. For examples, DSC is popularly used in patients with acute stroke due to its short scan time, while DSC or DCE provides the various perfusion indices for patients with tumor. ASL is useful for children, women who are expected to be pregnant, and in patients with kidney diseases which are problematic in nephrogenic systemic fibrosis (NSF). Perfusion MRI does not require any injection of radioisotopes. We expect that demand for perfusion MRI will be higher in evaluating drug efficacy and other treatment effects.

Partial internal amino acid sequences of the 15S ATPase from chick skeletal muscle were determined and found to be identical to the corresponding regions of the Mg2+_ATPase from Xenopus laevis oocytes, that is a close homolog of N-ethvlmaleimide-sensitive factor (called NSF) in hamster and Sec18p in yeast, both of which are believed to plaN an essential role in vesicle fusion in secretory process. Thus, the 15S Arpase in chick skeletal muscle maw also belong to a protein family of the "vesicle fusion proteins". Unlike the Mg2'-Afpase with an isoelectric point (pl) of 5.5, however, the 15S Arpase was separated into four spots with pls of 4.9,6.4 and 6.9 upon analysis by twoiimensional gel electrophoresis. In addition, the anti-15S ATPase IgG was found to be capable of interacting with the 265 protease complex upon analysis by immunoprecipitation. Moreover, immunoblot analysis revealed that the anti-155 Arpase IgG recognizes three subunits, ko of which show the same mobilities as the 510-kDa subunit 4 and 48-kDa subunit 7 of the 26S protease complex that are known to contain a highly consented ATP-binding motif. These results surest that a common antigenic site, likely the consensus nucleotide-binding site, exists in the 15S ATPase and the 26S pretense complex and hence both the enzymes maw also be related ATPases.d ATPases.

The long-lived radionuclide, $^{10}Be$, is produced by cosmic-ray effects in the atmosphere of the earth as well as its surface and that of other planetary surfaces and atmospheres. Accelerator mass spectrometry (AMS) was developed in late 1970s, which made $^{10}Be$ terrestrial measurements more feasible. Since then, many research applications of $^{10}Be$ for both terrestrial and extraterrestrial applications have been developed, which parallel the wide range of radiocarbon ($^{14}C$) research applications. This paper summarizes production mechanisms of $^{10}Be$ both in the atmosphere and on the surface of terrestrial and extraterrestrial environments and also provides numerous $^{10}Be$ research applications in the fields of geomorphology, oceanography, archaeology, glaciology, cosmochemistry, climatology, and planetary science. We also review some $^{10}Be$ AMS research applications.

Transmission lines systems are important components of the electrical power infrastructure. However, these systems are vulnerable to damage from high wind events such as hurricanes. This study presents the results from a 1:50 scale aeroelastic model of a multi-span transmission lines system subjected to simulated hurricane winds. The transmission lines system considered in this study consists of three lattice towers, four spans of conductors and two end-frames. The aeroelastic tests were conducted at the NSF NHERI Wall of Wind Experimental Facility (WOW EF) at the Florida International University (FIU). A horizontal distortion scaling technique was used in order to fit the entire model on the WOW turntable. The system was tested at various wind speeds ranging from 35 m/s to 78 m/s (equivalent full-scale speeds) for varying wind directions. A system identification (SID) technique was used to evaluate experimental-based along-wind aerodynamic damping coefficients and compare with their theoretical counterparts. Comparisons were done for two aeroelastic models: (i) a self-supported lattice tower, and (ii) a multi-span transmission lines system. A buffeting analysis was conducted to estimate the response of the conductors and compare it to measured experimental values. The responses of the single lattice tower and the multi-span transmission lines system were compared. The coupling effects seem to drastically change the aerodynamic damping of the system, compared to the single lattice tower case. The estimation of the drag forces on the conductors are in good agreement with their experimental counterparts. The incorporation of the change in turbulence intensity along the height of the towers appears to better estimate the response of the transmission tower, in comparison with previous methods which assumed constant turbulence intensity. Dynamic amplification factors and gust effect factors were computed, and comparisons were made with code specific values. The resonance contribution is shown to reach a maximum of 18% and 30% of the peak response of the stand-alone tower and entire system, respectively.
