      • Phanerochaete chrysosporium의 액체 배양 및 Lignin Peroxidase 생산

        박세근,정명선,김영관 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

        This study characterizes the growth of white rot fungi Phanerochaete chrysosporium IFO 31249 and lignin peroxidase(LiP) activity in different submerged culture media. P. chrysosporium was grown in the form of pellet of various sizes from a spore inoculum under shaking liquid culture condition. While the growth of mycelia was higher under the nitrogen-sufficient culture than under the nitrogen-limited culture, ligninase activity was relatively lower. The lignin peroxidase appeared in nitrogen-limited culture and was suppressed by excess nitrogen. High level(40U/l) of lignin peroxidase activity was obtained in the growth medium containing 1.5mM veratryl alcohol, a secondary metabolite of P. chrysosporium. Lignin peroxidase production was not observed under conditions of nitrogen sufficiency or in balanced media, suggesting that control parameters could increase the activity by manipulating the secondary metabolism.

        한국 총선에서 나타난 현직자의 재선 추이에 관한 분석 : 16∼18대 총선 결과를 중심으로

        박명호,김민선 동국대학교 사회과학연구원 2008 사회과학연구 Vol.15 No.1

        이 논문은 최근 한국 총선에서 나타난 현직자의 재선추이를 분석하고자한다. 현직의원의 재선은 소선거구제에서 두드러지며 그 원인에 관한 설명도 다양하다. 소선거구제에서는 유권자들이 후보자에게 직접 선호를 표시하므로 의원들은 지역구에서 중앙당의 통제와는 별도로 선거구민의 요구를 충족시킴으로써 독자적인 지지기반을 쌓기 위해 노력한다. 따라서 현직의원의 득표율은 계속 증대해 왔다. 분석결과 한국의 국회의원 선거에서 재당선율은 16대 총선에서 60.7%, 17대 총선에서 59.2%, 그리고 18대 총선에서 69.8%로 계속 증가하는 추세이다. 하지만 재당선율은 선수, 소속 정당, 그리고 지역에 따라 상이하게 나타났다. 이러한 발견은 한국선거에서의 현직효과에 대한 심층적 분석 및 요점을 제기하기에 충분하다. This article analyzes whether incumbents differ from challengers in voting outcome in the Korean General Elections. Incumbent are more likely to win elections than their opponents . We use data from 2000 to 2008 Korean General Elections to test hypotheses about "Incumbency Effect". We find that incumbents are more likely to reelect in Korean General elections. And various conditions-province, district, and candidate level factors-result in the likelihood that incumbents are reelected in Korean General Elections.

        하절기 단열 성능 향상을 위한 통기성 지붕의 통기 구조에 관한 실험적 연구

        박상훈(Park, Sang-Hoon),조구상(Jo, Goo-Sang),이선우(Lee, Sun-Woo),여명석(Yeo, Myoung-Souk),김광우(Kim, Kwang-Woo) 대한건축학회 2014 대한건축학회논문집 Vol.30 No.9

        The thermal performance of the building envelope is mainly required for guaranteeing a comfortable and hygienic interior climate. A roof is a part of the building envelope which provides protection from the thermal damage of the sun. To improve this protection ability, we can consider using a ventilated roof, which has a ventilation layer known as a cavity, beneath the roof cover panel. The objective of this study is to evaluate the influence of such factors as the slope of the roof, size or shape of the openings (i.e. inlet or outlet), effective cross section and cavity depth on the improvement of the air flow in the cavity for better thermal performance of the ventilated roof. In this study, the influence on air flow which is caused by the characteristics of these elements is researched. The evaluations are carried out by way of experiments.

        최명애,박승현,권원경,김선구,안혜영,김윤경 서울대학교 간호대학 간호과학연구소 1999 간호학 논문집 Vol.13 No.1

        The purpose of this study was to explore the effect of informational intervention on coping of mother's stress in unplanned childhood hospitalization. Thirty four mothers of the hospitalized children, 24 months to 60 months old, were randomly assigned to experimental and control group. Child behavioral information and parental role information was given to experimental group by booklet and cassette tape. The state-trait anxiety was measured within 12 to 24 hours following hospitalization, the state anxiety was measured during from 24 hours to 48 hours, and the parent participation with care of children, and the parent support during invasive procedures was measured during 48 hours to 72 hours after hospitalization. The data was collected from May, 1997 to October, 1998 at B hospital in Seoul. Data was analyzed with X²-test, non paired t-test, ANCOVA test and Wilcoxon test using SAS program. Results were obtained as follows: 1. There were no difference in the state anxiety during the period of hospitalization and after discharging from hospital between experimental and control group. 2. Experimental group showed significantly higher scores on the parent participation with care of children than control group(P=0.03). 3. The parent support during invasive procedures of experimental group was significantly greater than that of control group(P=0.0167). The results suggest that information intervention regarding child behavioral information and parental role information may enhance both the parent participation with care of children and the parent support during invasive procedures.

        This study was carried out to investigate the influences of feed containing activated charcoal on the performances of calves The daily weight gain, feed intake, feed requirement and the content of ammonia in the excreta were measured. The experiment was conducted with 10 male calves for 30 days. Each were equally divided with treatment group and control group and for the treatment group's animal fed diets containing 1.0% activated charcoal. The daily weight gain of calves were decreased by 1.92% when they were fed activated charcoal(1.02㎏/day) compared to that of control calves(1.04㎏/day) and the daily feed intake of treatment group(2.86㎏/day) was 10.06% lower comparing to the control group(3.18㎏/day). In case of feed requirement, the result showed 8.2% lower in the treatment group(2.80㎏) than control group(3.06㎏). The content of ammonia in excreta was significantly lower for treatment group(0.33ppm) than control group (2.67ppm)(p<0.05), which showed more improvement for reducing ammonia content in the treatment group with 87.6%(p<0.05). 본 연구는 사료에 활성탄을 첨가했을 때 송아지의 일당 증체량, 사료 섭취량, 사료 요구율 및 배설물의 ammonia 함량에 미치는 영향을 규명하기위해 실시하였다. 홀스타인 수송아지 10두를 30일 동안 대조구, 시험구(활성탄 1%첨가)로 각5두 공시하여 시험하였으며, 실험 결과를 요약하면 다음과 같다. 송아지의 일당 증체량은 대조구(1.04kg/일)에 비하여 활성탄을 급여했을 때(l.02kg/일) 1.92% 감소하였고, 일당 사료 섭취량은 시험구(2.86kg/일)가 대조구(3.18kg/일)에 비해서 10.06% 낮았으나, 사료 요구율은 대조구(3.06kg/kg증체)에 비해 시험구(2.80kg/kg증체)에서 8.2% 낮은 결과를 나타내었다. 송아지 배설물의 ammonia 함량은 대조구의 2.67ppm에 비하여 시험구가 0.33ppm으로 87.6% 감소되는 개선효과를 보였다(p<0.05).
