본 연구는 우리나라 주요 양식어류인 넙치, Paralichthys olivaceus를 대상으로 육상수조식양식장 배출물 발효물의 어류 사료 첨가에 따른 혈액학적 변동에 미치는 영향을 검토하였다. 젖산균 및 효모를 사용하여 발효한 양식장 배출물의 이화학적 분석을 실시하였고, 발효물을 0.1, 0.5, 1.0 및 5.0% 농도로 8주간 투여하였다. 투여 4주째 및 8주째에 각 투여 구간별로 혈액학적 항목을 중심으로 그 차이를 확인하였다. 배출물 발효농도별 유의한 차이는 나타나지 않았지만, 분석시기에 따른 적혈구수, 혈색소 농도 및 혈색소 지수가 증가하는 경향을 나타내었으나, 주요 혈청 무기 및 유기성분은 배출 발효물 농도별로 유의한 차이는 나타나지 않았다. 또한 혈청 효소학적 조사에서는 조사시기별로 변동은 나타났지만, 동일 조시시기에서 각 구간별 유의한 차이는 나타나지 않았다. 따라서 이러한 육상 약식장 유래의 배출물 발효산물에 대한 다양한 방면의 연구가 진행되어야겠다. Effects of oral administration with fermented product from sewage in land-based seawater fish farm on haematological disturbance in the olive flounder, Paralichthys olivaceus was investigated. After 4 weeks of conditioning with a basal diet, fish were divided into 4 groups and provided experimental diet (0.1,0.5, 1.0 and 2.0%) supplement of fermented sewage for 80 days. Proximal analysis was performed for the product of sewage which was fermented by lactic acid and yeast. RBC count, hemoglobin concentration and hematocrit value were increased according to the treated periods, however, no statistical difference was observed between control and treatment groups. There were no significant difference in serum organic, inorganic compounds and enzyme activities between control and treatment groups. This study hypothesized that the supplement of fermented product from sewage in land-based seawater fish farm might be an additive sup plement for source of fish diet in view of haematological examination. Recycling of the sewage may be an economic artificial sources of diet for fish aquaculture practices.

In 1930's, capitalism gradually became established in Chosun. As Chosun's economy was incorporated into the global capitalistic system, the domestic economy became dependent on the international market. During this time, Kyeong-Seong was transformed into a capitalistic city. Various forms of modern facilities appeared, while urban consumerism constituted the city life. Thus, the everyday life in Kyeong-Seong demanded the acceptance of modern culture in order to adapt to the changing environment. Inside the city, people experienced modern civilization and urban consuming life, and came to adjust their form of living and their viewpoint of the world. This thesis examines the advertisement and text that appears in the newspapers, magazines, and other journalistic material of the thirties in order to determine how the commercials, romance, hobby or entertainment, and the newly discovered "pastoral" influenced the contemporary life and mind. Also, we intend to reveal how these factors took form in the contemporary literature. The contemporary Korean writers were inevitably surrounded by the popular and urban sensibility mentioned above. Even though unconsciously, or sometimes through negative criticism, this sensibility was included in their text. Even the nature that was considered to be a replacement of the desolate and inhuman city life was in fact a filtered form of nature - an image constructed by the popular culture and advertisements. Also, the romance described by the sensitive authors often took the form of a consumer love. Meanwhile, judging from the penetration of commercial statements which appears in several works, there was a growing desire to consume the image. Along with the newly adapted hobbies and leisure culture, the Korean life style went through a significant change, and so did the content of the contemporary novels. The urban sensibility formed in Kyeong-seong during the nineteen thirties can be defined as the common popular sensibility attained by people living in a capitalistic consuming culture. It is attitude of setting the commercial image as a model of life, and is the search of individual life in the standardized and uniform life style of the popular culture. Whether they chose to criticize it or saturate themselves in it, the contemporary writers were unavoidably related to this sensibility and life style.

There are three types of high fluidity concrete: powder based, VMA based, and combined. In the case of the powder based high fluidity concrete mixture, according to the textbook, increased viscosity due to the replaced fly ash can prevent segregation of coarse aggregate. On the other hand, decreased density of the powder due to the fly ash replacement can causes segregation but there is no report on this issue. Therefore, in this research, the segregation resistance and segregation evaluation method for powder based high fluid concrete mixture are evaluated. As a result, with increased replacing ration of supplementary materials, EIS value was decreased and apparently segregation resistance was increased. However, from the compressive strength evaluation depending on height of the cylindrical specimen, it was confirmed that the different of strength difference between top and bottom part of the specimen. Thus, following research regarding vertical segregation should be studied.

본 연구는 제주에 자생하고 있는 제주아그배의 생리활성, 즉 항산화 효과와 항염 효과를 알아보고자 수행하였다. 제주 아그배의 항산화 활성을 측정하고자 비교 분석한 결과, 제주 아그배 에탄올 추출물 (DPPH 소거활성 IC50 값, 16.1 μg/mL; NO 소거활성 IC50 값, 901.2 μg/mL; superoxide 소거활성 및 Xanthine oxidase 억제 활성 IC50 값, 42.5 μg/mL, 2.7 μg/mL) 은 좋은 항산화 활성을 보였고, 그 분획물 중에서는 에틸아 세테이트 분획물이 항산화 활성 실험 모두에서 높은 소거 활성을 나타내었다. 따라서 항산화 활성이 좋은 제주아 그배의 추출물의 항염증 효과를 탐색하기 위하여 대식 세포 모델을 이용하였다. LPS로 자극한 마우스 대식세포인 RAW 264.7 세포에서 NO 활성과 세포독성간의 상대적 비교지수인 선택지수를 이용하여 탐색한 결과 에탄올 추출물과 에틸아세테이트 분획물이 2.9와 12.2로 가장 높은 상대적 NO 생성 억제 활성을 보였다. 그리고 NO 생성 억제율에 대한 IC50 값은 각각 16.7 μg/mL, 4.1 μg/mL으로 나타났다. 이런 결과를 기초로 하여 제주아그배의 에탄올 추출물의 NO 감소가 iNOS 단백질 감소에 의한 것임을 확인한 결과, 시료를 처리한 RAW 264.7 세포에서 iNOS 단백질이 농도 의존적으로 감소하였다. 또한 iNOS 단백질의 억제가 mRNA의 감소로 인한 것인지 조사하고자, RT-PCR 을 통해 iNOS 의 mRNA 발현을 조사한 결과, 단백질과 마찬가지로 농도 의존적인 mRNA 발현 감소를 볼 수 있었다. 제주아그배의 에탄올 추출물을 농도 별로 처리하였을 때 유의적으로 COX-2 단백질과 mRNA 발현이 농도 의존적으로 억제하였다. 분획물 중에서는 NO 활성과 세포 독성간의 상대적 비교지수인 선택지수가 높았던 에틸아세테 이트 분획물이 에탄올 추출물보다도 NO, iNOS, COX-2의 억제 정도가 더 좋은 경향을 나타내었다. The antioxidant and anti-inflammatory activities of ethanol extract of Malus micromalus were studied in vitro. Ethanol extract of M. micromalus showed scavenging effects on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and nitric oxide (NO) radicals. In addition, ethanol extract of M. micromalus inhibited the generation of superoxide anion (O2 -) radical and uric acid by xanthine oxidase. We also investigated the effect of ethanol extract of M. micromalus on NO production in a lipopolysaccharide (LPS)-stimulated murine macrophage RAW 264.7 cells. Ethanol extract of M. micromalus significantly inhibited NO production and this inhibitory action was not due to the cytotoxicity. The expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was markedly down-regulated by ethanol extract of M. micromalus. These results indicate that the inhibitory action of ethanol extract of M. micromalus on NO production in LPS-stimulated macropages might be due in part to abrogation of iNOS and COX-2 protein induction. Taken together, this study suggests that ethanol extract of M. micromalus could contribute to the chemoprevention and therapy of oxidative stress and inflammation.
