In the past, there were many differences between living standard of urban area and that of rural area. And annual gross income of rural inhabitants did not reach that of urban laborers, but from 1974, income of rural dwellers became to reach over urban laborers' income. in early of 1980s, annual gross income of rural dwellers will be increased to ￦1,400,000 per house, which will encourage them to improve their living environment. To improve existing rural living standard to livable and decent living environment, it would be required to reform rural community function, its size and new living zone out of consideration for increase of annual gross income, and change of living pattern, their convention, size of production, cultivating method and income sources in rural areas. Through the investigation of existing environment conditions in rural area, we selected Homyong-Myon, Yechon-kun, Kyongsang-Bukdo as case study and tried to make actual rural planning of this area to show sampling study of rural renewal planning. It is recommendable that community facilities and existing living zone in rural area should be rearranged for the reasonable harmony with improved living environment and matching with existing administrative district as possible, new living zone had better be classified into 4 categories, as below: 1)Basic Living Zone This would include 50-70 households within about 1km semidiameter boundary where daily activities of inhabitants would be conducted. 2)First Living Zone This would include about 5-10 basic living Zones within about 2-3km semidiameter boundary where weekly activities of inhabitants would be conducted and elementary school facilities would be main focus of this community area. 3)Second Living Zone This would be main living Zone in rural community area and include 3-4 first living Zones within 4-6km semidiameter boundary where secondary school and Myon district office would be located and monthly activities of inhabitants would be main community behaviors in this area. 4)Third Living Zone This would be matching with Gun district living community and synthetic living center in rural community area within 15-30km semidiameter boundary. This thesis just shows convenient division of living Zones for decent rural community environment and functional relationships between each living Zones, but further study should be proceeded for the precise planning of community facilities-their location and scope of size in each living zone.

우영대,주용규,이호왕 대한감염학회 1998 감염 Vol.30 No.4

목 적 : 우리나라에서 한탄바이러스와 서울 바이러스에 의하여 발생하는 신증후출혈열을 예방하기 위하여 1990년 개발된 한타박스는 현재 상용화되어 있다. 한타박스가 시중에서 상용화되어 사용된 역사가 짧으므로, 예방접종자에서 항체지속기간에 관한 연구는 미흡한 실정이다. 본 연구에서는 신증후출혈열 예방백신인 한타박스를 접종한 사람들에서의 항체 특히 중화항체양전율과 항체지속기간을 조사하고자 하였다. 방 법 : 아산생명과학연구소에 근무하는 61명의 연구원들을 대상으로 신증후출혈열 예방백신인 한타박스를 한달간격으로 2회 기본접종하였다. 예방백신을 접종하기 전 대상자들이 혈청을 채취하여 한탄바이러스와 서울바이러스에 대한 항체음성임을 형광항체법과 중화항체법으로 확인하였다. 한타박스를 기본접종한 한달 후 및 일년 후 그리고 기본 접종한지 일년이 경과하여 1차 부스터 접종을 한 한달 후 및 2년여가 경과한 후와 2차 부스터 접종 한달 후의 백신접종자에서의 항체양성율 및 항체가를 간접면역형광항체법(IFA), 고비중입자응집반응(HDPA) 및 플라크감소 중화시험(PRNT) 등으로 비교 측정하여 배신접종자에서의 항체양성율, 형광항체가 및 중화항체가와 면역지속기간을 조사하였다. 결 과 : 1) 신증후출혈열 백신인 한타박스를 2회 기본접종을 하고 한달 후 혈청을 채취한 21명에서의 IFA, HDPA와 PRNT방법에 의한 항체양성율은 각각 20/21 (95.2%), 19/21 (90.5%), 14/21 (66.7%)이었으며, 평균 항체역가는 각각 262,248,120이었다. 2) 기본접종 1면 후 혈청을 채취한 40명에서의 IFA, HDPA와 PRNT방법에 의한 항체양성율은 저하되어 각각 25/40 (62.5%), 18/40 (45.0%) 그리고 9/40 (22.5%)이었으며 평균 항체역가는 각각 92,41,24.5 이었다. 3) 부스터접종이 효과를 조사하여 본 결과 기본접종 1년후 채혈한 14명에서의 IFA와 PRNT방법에 의한 항체양성율은 7/14 (50.0%), 3/14 (21.4%)이었으며 평균 항체역가는 각각 100.6, 47.1 이었다. 1차 부스터 접종 한 14명중 1개월후 채혈한 8명의 IFA와 PRNT방법에 의한 항체양성율은 8/8(100%), 8/8(100%)이었으며 평균 항체역가는 각각 852,182.5 이었다. 1차 부스터 접종한 20개월후 채혈된 12명의 항체양성율은 11/12 (91.7%), 9/12 (75.0%)이었으며 평균 항체역가는 각각 296, 33.3 이었고, 2차 부스터 접종한 3개월 후 채혈한 7명의 항체양성을율은 7/7 (100%), 6/7(85.7%)으로 항체 평균역가는 각각 548,46 이었따. 기본접종 1년후 1차부스터접종을 실시한 1개월후 채혈한 8명의 항체역가와 2차부스터접종을 실시한 한달후 채혈한 7명의 항체역가를 형광항체법과 중화항체법으로 조사한 결과 뚜렷한 항체역가의 증가를 나타내는 기왕성면역반응을 볼 수 있었다. 결 론 : 백신접종자에서 한탄바이러스에 대한 항체를 높게 유지하기 위해서는 2회의 기본접종과 기본접종 1년후 추가접종이 필요하며, 추가접종후 최소한 2년간은 항체가 지속적으로 유지된다는 사실을 증명하였다. Background : Hantavax™ was developed and has been used for prevention of hemorrhagic fever with renal syndrome caused by Hantaan and Seoul virus since 1990 in Korea. Since Hantavax™ has short usage history, the duration of antibodies persistancy in vaccinees was not well studied. Methods : Hantavax™ was inoculated to 61 people who work at Asan Institue for Sciences twice subcutaneously at one month interval according to the manufacturer's recommendation. Antibody titers of vaccinees were measured at 1∼4 months or 1 year after primary basic vaccination and a month, 1∼2 years after booster vaccination by indirect immunofluorescent assay (IFA), High density particle agglutination assay (HDPA), and plaque reduction neutralization test (PRNT). Results : Serconversion of twentyone vaccinees on 1∼4 months after primary vaccination were 20/21 (95.2%), 19/21 (90.5%) and 14/21 (66.7%) whose geometric mean antibody titers were 262,248,120; Forty vaccinees on one year after primary vaccination were 25/40 (62.5%), 18/40 (45.0%), 9/40 (22.5%) whose geometric mean antibody titers were 90,56,24 by IFA, HDPA, PRNT, respectively. Seroconversion of eight vaccinees on one month after booster vaccination were 11/12 (91.7%), 9/12 (75.0%) whose mean antibody titers were 296,33, and seven vaccinees on 3 months after second booster vaccination were 7/7 (100%), 6/7 (85.7%) whose mean antibody titers were 54,946 by IFA, PRNT, respectively. Conclusion : The boost vaccination is necessary at 12 months after primary basic vaccination of Hantavax™ for maintaining high level of antibodies against of Hantaan virus, and antibodies persist at least two years.

Enhancement of the anisotropic photocurrent in ferroelectric oxides by strain gradients

Chu, Kanghyun,Jang, Byung-Kweon,Sung, Ji Ho,Shin, Yoon Ah,Lee, Eui-Sup,Song, Kyung,Lee, Jin Hong,Woo, Chang-Su,Kim, Seung Jin,Choi, Si-Young,Koo, Tae Yeong,Kim, Yong-Hyun,Oh, Sang-Ho,Jo, Moon-Ho,Yang, Nature Publishing Group 2015 Nature nanotechnology Vol.10 No.11

The phase separation of multiple competing structural/ferroelectric phases has attracted particular attention owing to its excellent electromechanical properties. Little is known, however, about the strain-gradient-induced electronic phenomena at the interface of competing structural phases. Here, we investigate the polymorphic phase interface of bismuth ferrites using spatially resolved photocurrent measurements, present the observation of a large enhancement of the anisotropic interfacial photocurrent by two orders of magnitude, and discuss the possible mechanism on the basis of the flexoelectric effect. Nanoscale characterizations of the photosensitive area through position-sensitive angle-resolved piezoresponse force microscopy and electron holography techniques, in conjunction with phase field simulation, reveal that regularly ordered dipole-charged domain walls emerge. These findings offer practical implications for complex oxide optoelectronics.
