최시영 건국대학교 건축전문대학원 2011 국내석사

서울에는 조선의 역사와 흔적을 고스란히 간직하고 있는 문화재들이 있다. 그것은 서울이라는 도시가 조선시대 한양으로써 도시 전체가 거대한 도성으로써의 역할을 하였기 때문이다. 조선건국 초에 태조가 한양으로 수도를 옮기기 위하여 궁궐과 종묘를 먼저 지은 후, 태조 4년(1395) 도성축조도감을 설치하고 한양을 방위하기 위해 성곽을 쌓도록 하였다. 석성과 토성으로 쌓은 성곽에는 4대문과 4소문이 있다. 현재는 삼청동, 장충동, 일대의 성벽 일부와 남대문, 동대문, 동북문, 홍예문만이 남았다. 성울 성곽은 조선시대 성 쌓는 기술의 변화과정을 살펴볼 수 있는 좋은 자료이며, 조상들이 나라를 지키려는 호국정신이 깃든 귀중한 문화유산이다. 서울 성곽은 하나의 문화재로써 새롭게 관심을 받고 있으나 시대에 변화에 따라 한양에서 서울로, 조선시대에서 근대를 거쳐 현재까지 많은 역사와 문화가 변화되어진 지금 도심지와 자연 속에 방치 되어진 하나의 경계로써의 구조물에 불과한지 생각을 해봐야 한다. 아울러 그것에 대한 본질이 달라진 지금 도시와 문화재의 의미를 다시 생각해봐야한다. 본 연구는 서울의 도심지에 중요한 지리적 문화재인 사적 제 10호인 ‘서울 성곽’ 의미를 파악하고, 현황을 알아본 뒤 유실되어진 부분의 복원에 대한 현대적인 관점에서 접근하려한다. ‘서울 성곽'의 도심지 문화재복원에 있어서 원형적인 복원이 아닌 현대적인 복원의 관점으로써 건축적 어휘와 시각으로 재해석하여 문화재와 도심이 공존 할 수 있는 프로젝트로 계획해 본다. 따라서 서울 성곽의 유실된 장충체육관과 광희문을 이어주는 명사3길을 해당 지역으로 선정하여, 그곳에 역사적 흔적을 파악하고 장소성에 의존하는 역사관이 아닌 역사관에 의존하는 복원의 의미로 설정하여 100년이 지난 지금의 흔적을 본존해서 미래에 또 다른 문화재로써의 역할로 자리 잡을 수 있게 만들고자 한다. 현재, 잔존하고 있는 성곽의 복원의미와 도시와 호흡할 수 있는 건축적인 관점에서 연구하고, 시민들과 소통 할 수 있는 역사와 문화의 새로운 축으로 자리 잡도록 제시해 본다.

This paper describes the design and fabrication of a clock and data recovery circuit (CDR). The proposed CDR can also remove virtually all of the process technology and environmental variability by using a self-biasing method. The proposed CDR circuit can achieve a wide acquisition range without using the reference clock. This clock and data recovery circuit utilizes a linear phase detector (PD), frequency detector (FD), a charge pump(CP), and a self-biased ring voltage controlled oscillator (VCO). Compared to the ordinary CDR with phase-locked loop (PLL) for the reference clock and the proposed clock and data recovery circuit, the proposed CDR circuit has an additional frequency loop using a frequency detector. As a result, it has a wide acquisition range without using the reference clock. The linear PD outputs the phase error information through the Pup/Pdown signal and the FD outputs the frequency error information through the Fup/Fdown signal. Therefore these four signals control the two charge pumps. The voltage controlled oscillator is based upon the differential buffer delay stages with symmetric loads and replica-feedback biasing. The VCO used in this CDR circuit has a wide operating frequency range from 150 MHz to 2.0 GHz. This clock and data recovery circuit was designed by using CMOS 0.18μm technology and this work was verified by using SPECTRE tools.

A total of 150 21-day-old weaned piglets [(Yorkshire × Landrace) × Duroc] were randomly assigned to 3 groups based on the average initial body weight (6.96 ± 0.21 kg) to evaluate the effects of dietary supplementation of live yeast, paraprobiotic, and hydrolyzed yeast mixture on growth performance, nutrient digestibility, fecal bacteria counts, fecal calprotectin contents, and diarrhea rate in a 42-day experiment (phase 1: days 1-14; phase 2: days 15-42). There were 10 replicate pens per treatment with 5 pigs per pen (mixed sex). The experimental diets were a basal diet, without additive (CON), a basal diet supplemented with pharmacological levels of zinc oxide (ZnO; TRT1), and an experimental treatment including live yeast, paraprobiotic, and hydrolyzed yeast mixture (TRT2). Pigs in TRT1 group were provided with a basal diet + 3000 ppm ZnO during phase 1, and a basal diet during phase 2. Pigs in TRT2 group were provided with a basal diet + 0.02% live yeast + 0.08% paraprobiotic + 1.0% hydrolyzed yeast mixture during phase 1, and a basal diet +0.01% live yeast + 0.04% paraprobiotic mixture during phase 2. Pigs in TRT1 group had higher body weight on day 14 and 42, average daily gain (ADG) during days of 1-14, 15-42 and 1-42, feed efficiency during days of 15-42 and 1-42, apparent nitrogen digestibility, and apparent energy retention than those in CON group. In addition, feeding strategy of live yeast, paraprobiotic, and hydrolyzed yeast mixture led to higher body weight on day 14 and 42, ADG during days of 1-14 and 1-42, apparent nitrogen digestibility, and apparent energy retention than those in CON group. There were no significant differences in measured parameters between TRT1 and TRT2 group. Therefore, we demonstrate that live yeast, paraprobiotic, and hydrolyzed yeast mixture supplementation had comparable effects to ZnO on the increase of nutrient digestibility in weaned piglets and subsequently improvement of growth performance. The present research was conducted to investigate the effect of Pediococcus acidilactici probiotic on the growth and production performance, egg quality, nutrient digestibility, body composition, calcium and phosphorus metabolism, and bone, ovarian, and small intestine related gene expression in laying hens. Total of 480 Hy-line brown laying hens (50-wk-age) were randomly assigned to 2 treatments with 20 replication and 12 hens per replication (1 hen/cage) in a 14-wk feeding trial. The dietary treatments were CON (basal diet) and TRT1 (CON with 0.1 % P. acidlactici probiotic). As a results, hens of TRT1 significantly reduced the downgraded egg percentage during weeks 9 and 11, while, the hens significantly enhanced marketable laying rate compare to control group. At the end of the experiment (wk-14), egg production (P = 0.045) was significantly improved in TRT1 group compare to control. In addition, dietary inclusion of probiotic supplementation significantly increased Haugh unit (P < 0.05) at week 7 and 13. The eggshell thickness was significantly improved in TRT1 during week 7. At week 13, hens fed 1 % probiotic supplement had significantly improved egg shell color, and yolk weight (P < 0.05). In addition, a significant effect were observed on albumen height and albumen weight in probiotic supplementation treatment group week 9. Overall, our results demonstrated that dietary inclusion of probiotic supplementation had significantly enhanced (P < 0.05) bone calcium and phosphorus, bone strength of cohesiveness in laying hens. At the end of the experiment, the expression of CALB1, ATP2B1, and SLC34A2 gene was upregulated in small intestine of hens fed probiotic treatment group. In addition, the expression of CALB1 was downregulated in laying hen ovarian by probiotic supplementation treatment group. In conclusion, the results found in this trial indicated that P. acidlactici probiotic supplementation in laying hen diet has a potential to improve the egg production, egg quality, bone cohesiveness, bone calcium and phosphorus, and egg size. In addition, small intestine-related gene ATP2B1, CALB1 and SLC34A2 and CALB1 genes in ovary were involved in laying hen’s performance.

산모의 연령에 따른 태반 내 산화 스트레스 및 세포고사에 관한 연구

최시영 이화여자대학교 대학원 2009 국내석사

산모의 연령은 선천성 기형아 출산 및 산전합병증 증가의 중요한 변수로서 간주되며, 35세 이상의 산모를 고령산모로 정의한다. 산모의 연령 증가는 태반의 동맥경화를 가속화시키고 이로 인한 태반 혈류 장애가 산전합병증의 발생빈도를 높이는 것으로 여겨지나, 이는 역학적 연구 결과에 기초한 것으로 태반을 이용하여 연령에 따른 차이를 분석한 연구는 미비하다. 따라서 본 연구에서는 정상분만 산모들을 대상으로 연령에 따른 태반 조직의 산화손상정도와 세포고사의 수준을 비교함으로써 산모의 연령이 태반의 기능에 영향을 줄 가능성을 조사하였다. 연구대상으로는 2005년 1월부터 2007년 12월까지 이대목동병원 산부인과에 내원한 환자 695명을 대상으로 하였다. 고령산모에서의 산전합병증 발생빈도를 살펴보고, 정상 산모들만을 대상으로 25세에서 29세까지, 30세에서 34세까지, 35세 이상의 세 그룹으로 나누어 태반의 산화 스트레스와 세포고사 차이를 확인하기 위해 heat shock protien 70, endothelial nitric oxide synthase, manganese superoxide dismutase, glutathione peroxidase, 8-hydroxy-2'-deoxyguanosine을 산화 스트레스의 지표로서, M30 cytoDEATH를 세포고사의 지표로서 사용하였으며 westernblot 분석과 면역조직화학염색법을 시행하였다. 본 연구 결과, 고령산모군에서 임신당뇨병, 조산의 발생빈도가 증가하였으며, 태반 내 산화 스트레스와 세포고사 또한 고령산모군에서 증가함을 관찰하였다. 이상의 결과로 볼 때, 산모의 연령 증가가 태반 내 산화 스트레스와 세포고사를 증가시킴으로써 부정적인 임신결과에 영향을 줄 수 있으며, 이는 연령증가에 따른 자궁 내 환경변화가 출생 후 발달과정에도 영향을 줄 수 있음을 시사하고 있다. Early several studies reported that advanced maternal age, over 35 years, is a risk factor for various kinds of prenatal complications and neonatal outcomes including Down syndrome. However almost studies about effects of maternal age on pregnancy outcome were epidemiological studies throughout the retrospective review of database. Therefore we investigated the effects of the age factor on placental oxidative damage and apoptosis in normal pregnant woman by exclusion of pregnant woman with prenatal complications. We confirmed the incidence of prenatal complications in the advanced maternal age group among 695 pregnant woman who visited Ewha Womans University Hospital from 2005 through 2007. And then we examined the impact of maternal age on level of placental oxidative stress and apoptosis across three maternal age group quantiles(25-29, 30-34, 35<) throughout the Westernblot analysis and immunohistoche-mical staining. The rate of gestational diabetes(6.8%) and preterm delivery(3.0%) in advanced maternal age group statistically greater than control group. We observed that increments of placental eNOS, HSP70, MnSOD, GPx, 8-OHdG and M30 expression in advanced maternal age group(p<0.05) compare to aged less than 35 years group. Therefore placental oxidative stress increase according to maternal age. These findings suggest that maternal age affects the placental dysfunction and fetal development after birth outcome
