The flavor and organoleptic properties of Hongju prepared by Kokja and Koji method were tested. There was no great difference of total acid in Hongju with different fermentation methods. The alcohol content of Hongju prepared by Koji method was higher than that of Kokja method and methanol content was very little as about $0.02{\sim}0.03$ mg/ml in all samples. The aldehyde content was $7.5{\sim}32$ mg% and fusel oil was higher in Hongju prepared by Koji method than that of Kokja method. As the result of sensory evaluation, new Hongju, S-N prepared by Kokja method with wheat and rice was to be best quality.

In this paper, recent research trends and activities on structural health monitoring (SHM) of civil infrastructure in Korea are reviewed. Recently, there has been increasing need for adopting smart sensing technologies to SHM, so this review focuses on smart sensing, monitoring, and assessment for civil infrastructure. Firstly, the research activities on smart sensor technology is reviewed including optical fiber sensors, piezoelectric sensors, wireless smart sensors, and vision-based sensing system. Then, a brief overview is given to the recent advances in smart monitoring and assessment techniques such as vibration-based global monitoring techniques, local monitoring with piezoelectric materials, decentralized monitoring techniques for wireless sensors, wireless power supply and energy harvest. Finally, recent joint SHM activities on several test beds in Korea are discussed to share the up-to-date information and to promote the smart sensors and monitoring technologies for applications to civil infrastructure. It includes a Korea-US joint research on test bridges of the Korea Expressway Corporation (KEC), a Korea-US-Japan joint research on Jindo cable-stayed bridge, and a comparative study for cable tension measurement techniques on Hwamyung cable-stayed bridge, and a campaign test for displacement measurement techniques on Sorok suspension bridge.

The present study were conducted to determine physiological activities and antioxidant effects [2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, reducing power, Ferric Reducing Antioxidant Power (FRAP) and Fe2+ (ferrous ion) chelating capacity] of 70% methanol, chloroform:methanol, 2:1 volume ratio (CM) and ethyl acetate extract of turmeric (Curcuma longa L.). Bioactive compound of tannin $0.125{\pm}0.007mg$ Catechin Equivalent (CE)/g dry weight. Turmeric extracts yield were 70% methanol 16.54%, CM 5.64% and ethyl acetate 4.14%, respectively. Antioxidant activity of the samples exhibited a dose-dependent increase. Results showed that extraction solvent had significant effects on total flavonoid content and antioxidant effects of ethyl acetate. But ferrous ion-chelating capacity of 70% methanol extract was higher than CM and ethyl acetate extract. From the results of this study, turmeric can be utilized as a valuable and potential nutraceutical for the functional food industry.

선행 연구개발한 집단감시 디지털 시스템(Group Digital Surveillance System for Fishery Safety and Security, GDSS- F2S)은 대단위 양식장에 침입하는 도적을 방어하기 위하여 레이더 추적정보와 적아식별 정보를 제공하는 시스템이다. 그러나 GDSS-F2S에서 제공하는 두 가지 정보만으로는 도적행위를 입증할 수 있는 법적 증거자료로 미흡하다. 본 논문에서는 이러한 문제점 해결방안의 하나로 CCD 카메라를 이용한 영상획득 장치를 개발하여 GDSS-F2S에 부가한 연구내용을 기술한다. 영상획득 장치 개발에 앞서, 실험지역의 지리적인 특성을 고려한 도적침입 예상경로 분석과 도적행위 시나리오를 기반으로 유효한 대응수단을 검토한 결과, 영상획득 장치가 유효한 대응수단임을 확인하였다. 영상획득 장치는 저가이변서 성능이 우수한 0.0001 룩스의 초저조도 CCD 카메라와 부가장치를 이용하여 개발하였다. 6개월 이상의 장기 현장실험을 통하여 본 연구에서 개발한 시스템을 평가한 결과, 주간은 물론 1 미터 앞도 식별할 수 없는 야간에도 차량의 행동과 번호판 및 사람의 행동과 인상착의 등의 영상정보를 확보할 수 있었다.

Leiomyosarcoma is defined as a malignant smooth muscle tumor or a tumor that arises from smooth muscle and it is found as firm. white and lobulated mass. Canine uterine Ieiomyosa- rcomas are rarely associated with clinical signs. We surveyed(one case which was treated at veter- inary medical leaching hospital of Seoul National University. Through this report we studied the meshed fur diagnosis of uterine leiomyosarcoma by symptom, hematological method and ultrahonog- raphy. To determine uterine leiomysarcoma is difficult due to similarity of clinical signs to pyometra. Especially symptoms could not be noticed even by dogs owners until dogs have an elevation of the number of white blood cells. We conclude ultrasonographic observation and experimental laparotomy are of great value to diagnose the uterine liomyosarcoma.

It is well-known that onion and garlic of Allium family have been cultivated for major food since ancient times. Especially garlic is known for containing protective materials against cardiovascular disease, neoplasm and cancer, and decreasing cholesterol value. Hemolytic anemia was first reported by Goldsmith in onion-fed cattle in 1909. Subsequently, similar effects have been reported in cattle, horses, sheep, dogs and cats. This toxic effect has been attributed to npropyl disulfide which causes oxidant damage to erythrocyte cell membrane. There are few reports on overconsumption of garlic. Kim et al. reported in 1999 that 45% of Jindo dogs in korea have erythrocytes characterized by high Na-K-ATPase activity with high K and low Na concentrations (HK) which easily results in hemolytic anemia. The purpose of present report is to determine whether garlic-induced hemolytic anemia occurs in normal erythrocytes characterized by complete lack of Na-K-ATPase activity with low K and high Na concentrations (LK) when LK dogs are fed large amounts of garlics. We found in this experiment that Erythrocyte count, PCV and Hemoglobin concentration decreased significantly, and GSH and Met-hemoglobin concentrations increased. Consequently, we determined that overconsumption of garlic induces hemolytic anemia in LK dogs.
