The methanolic extract of Hibiscus vitifolius flowers (HVE), was evaluated for neurophamacological activities by carrying out rota rod, locomotor activity and traction performance in mice and swim endurance activity in rats in different dosages (10, 30 and 100mg/kg body weight). HVE showed a significant effect on central nervous system by increasing the time taken for rota rod, traction performance and locomotor activity while swimming time was found to be decreased when compared to normal control animals. These results suggest that HVE possess significant anxiolytic and anti depressant activity which may be attributed to the presence of flavonoid in HVE.

Development of air navigation and avionics technologies led to solve the problems that conventional ATM system had. The International Civil Aviation Organization developed the Aviation System Block Upgrades (ASBU) initiative in order to harmonize global ATM planning and technology upgrades and urged to implement the recommendations for the member States. The ASBUs provide the road map to assist air navigation service providers in the development of their individual strategic plans and investment decisions. In this paper, the operational concepts in 2 performance improvement areas, Airport Operations and Globally Interoperable System and Data in ASBUs, have been summarized. In Airport Operations area the new management technologies and required systems are presented for optimizing the traffic flow in airport area and terminal airspace. Data format standards and required systems presented for information integration and usage of the new system under Globally Interoperable System and Data area.

본 연구는 Percoll,Swim-up 그리고 Glass-wool 여과법의 세가지 정자분리 방법에 대한 정자 회수율, 생존율과 첨체반응율, 그리고 체외수정 후 배양시간에 따른 전핵형성율,수정란의 발달율과 세포할구수에 대한 효과를 조사하고자 실시하였다. 도축된 암소로 부터 채취한 난자를 22시간 체외배양 후 성숙된 난자를 체회수정시켰다. 수정 후 배양시간에 따라 존핵율을 조사하였으며 48시간에 분할율,192시간에 배반포기 발달율 및 세포할구수를 각각 비교 조사하였다. 정자의 첨체반응과 생존율은 처리군간에 차이가 없으나 회수율에 있어서 percoll 처리군이 다른 두 처리군보다 유의적으로 높았다(p<0.001).수정 후 배양시간별 전핵형성에 있어서도 percoll 처리군이 다른 두 처리군보다 빨리 진행됨을 볼 수 있다. 분할율에 있어서는 처리군간에 유의적 차이가 없으나.배반포기 발달율과 세포할구수에 있어서는 pecoll 처리군이 다른 두 처리군보다 유의적으로 높았다(P<0.05). 이상의 결과로 보아 percoll 처리에 대한 정자분리 방법은 정자 회수율이 높고 수정시 전핵형성 시간이 단축되어, 그 결과로 배반포기 발달율과 수정란의 세포할구수에 효과적임을 알 수 있었다.

Follicular fluid influxed into the oviduct during ovulation may affect movement of sperm for fertilization Thus, in this study, the effect of follicular fluid, obtained from follicles of l0mm in diameter, on number and quality of sperm recovered by swim-up separation was investigated and sperm-movement stimulating components extracted from follicular fluid with methanol and isooctane were separated by gel filtration with Sepadex G-1O, G-25 and G-1OO gels, and were isolated by electrophoresis with SDS-PAGE mini gel. The results obtained were as follows; 1. Diluted follicular fluid stimulated sperm movement. 2. Sperm-movement stimulating factors were in methanol extract. 3. Sperm-movement stimulating effect of methanol extract appeared in fraction I among fractions recovered after gel filtration. And the fraction I contained proteins indicating 4 major bands as about 47, 43, 25 and 14 kilodaldons and 5 minor bands as about 67, 58, 23, 22 and 21 kilodaldons. 4. The fraction I recovered from G-100 gel showed significantly low percentage of motile sperm and had no protein indicating the band of 67 kilodaldons among the minor bands.

Calcitonin gene-related peptide (CGRP) expressing neurons are distributed widely throughout the central and peripheral nervous systems. Due to its distribution and pharmacological studies, CGRP has been implicated to be involved in anxiety, fear and depression. In this study, ${\alpha}CGRP-knockout$ mice were used to assess the consequences of removing this neuropeptide to the mice behaviors. ${\alpha}CGRP-knockout$ mice performed equally as well as wild type mice in the light-dark transition test and in the elevated plus maze test of anxiety. ${\alpha}CGRP-null$ mice behaved similarly as wild-type mice in the Porsolt swim test of depression. They also exhibited normal learning and memory in the fear conditioning tasks. It is concluded that ${\alpha}CGRP$ is not essential for mice to be able to perform these tests, despite the presence of ${\alpha}CGRP$ in the relevant regions of the brain.

Vibrio septicemia,, resulting in high mortality, has been caused by Vibrio vulnificus. Ingestion of marine products or contact with sea water contaminated with Vibrio vulnificus can cause septicemia. Vibrio vulnificus has been detected world wide and west sea area of Korea, Kum river estuary in particular, showed high detection rate. Higher detection rate of Vibrio vulnificus were reported in the bottom deposit with low depth of water, low salinity, and high COD. Man with the liver disease can easily come down with Vibrio septicemia and the main source is the sliced raw fish dish. The preventive measure for this disease is to wash raw fish material thoroughly with tap water and handle in sanitary conditions. Washing with sea water is strictly prohibited . It may be necessary to forbid the small-scale businessmen from selling the sliced ray fish dish in the vicinity of seashore. Man with the liver disease of diabetes should not swim or consume the raw fish dish in the contaminated area during summer.

Modern Air Traffic Management has been shifted from the conventional vector- based clearances to trajectory based operations (TBO) concept which utilizes four-dimensional trajectory based on the internationally interoperable information using Globally Unique Flight Identifier (GUFI). This study reviews the development for TBO-related standards and Flight Information Exchange Model (FIXM), which has been discussed by the ICAO Air Traffic Management Requirements and Performance Panel (ATMRPP). In addition, plans for the next step with TBO and the Republic of Korea's participation on the Mini-Global Demonstration were also introduced.

웹에 대한 사용자의 다양한 요구와 더불어 시맨틱 웹에 대한 연구가 활발하게 이루어지고 있다. 이러한 연구 중에 대표적인 예가 바로 온톨로지의 구축에 대한 연구이다. ICS-FORTH는 온톨로지 구축을 위한 대표적인 시스템으로 SWIM을 이용한 분산된 환경에서의 독립된 온톨로지 즉, 관계형 데이터베이스와 XML로 된 온톨로지의 통합이 가능하도록 하였다. 또한, 통합된 온톨로지를 RDF/S를 기반으로 하는 뷰의 형태로 사용자에게 제공하여 추론이 가능한 질의 처리가 가능하도록 하였다. 이에 따라, 본 논문에서는 W3C에서 제안한 OWL을 통합의 대상으로 통합의 범위를 확장하기 위한 기법을 제안한다. 제안한 기법은 RDF/S를 확장한 다양한 관계의 기술이 가능하기 때문에 사용자가 RQL 형태의 질의를 미들웨어에서 처리할 수 있는 형태로의 변환하는 기존 기법의 확장된 형태이다. 이러한 확장을 통하여 기존 온톨로지 통합의 범위를 확장하여 보다 많은 사용자의 다양한 요구에 대응할 수 있다.

This paper suggests the system for searching and application is to be in combination between existing hair art area and Image/Video processing area. This proposed system usually saves various hair types into a database, then, users send images of their face over the internet by using WebCam. Finally, they can find the hair types for users. Hair cutting is technology that form draft to make hair style. Man cut must decide how in image of sinciput, image of side bean curd, after lower image must operate. Silhouette is produced as is different by change of this three places. Customer increases in the beauty salon and beauty salon chain being changed, research about beauty art is necessary point of time. In this treatise, our country of when swim and operate haircut about problem that happen sample survey and analysis.
