High-Frequency Agrobacterium-Mediated Genetic Transformation of Tongil Rice Varieties
Park, MinChul,Shin, JunHye,Kim, NarYung,Cho, HongJoo,Park, SeongHee,An, KyungSook,Lee, SiChul,An, GynHeung 한국식물학회 2003 Journal of Plant Biology Vol.46 No.1
We investigated the frequency of callus induction from mature-seed scutella of 39 varieties of Tongil rice (Oryza sativa japonica x indica). These were divided into two groups according to condition of the callus at the time of incuction. Members of the first group, which developed brown calli, were further classified into two types (B1 or B2), based on the extent of their color change and callus congition. Tissues in the second froup developed yellow calli, with varieties being placed into one of three types (Y1, Y2, or Y3) according to solidity. Type-Y1 seeds generated suitably soft calli that were healthy and grew rapidly. These calli were transformed with binary vector pGA2722 via Agrobacyerium-mediated co-cultivation. The vector contained the hygromycin-resistance selectable marker and a gus reporter gene with an intron that is functional in plant cells but not in Agrobacterium. Most vatieties that formed brown calli failed to generate transformants. Ligewise, several varieties wuth suitably soft calli also failed. Among the 16 transgormable varieties, the final regeneration frequencies ranged from 1.0 to 10.7%. The highest frequency was achieved by the variety Tongil, which also had the most rapidly growing calli. DNA gel-blot analysis revealed one to three copies of the introduced gus gene.

Demographic transition drives changes in consumer demand for food products. This study examines how rising incomes and population trends affect spending on food purchased for home. The objective of this study is to characterize the relationships between selected socio-demographic factors and food selection among South Korean households. Panel data from Rural Development Administration (RDA) in South Korea in 2010 was used (n=971). Household food purchases were classified into one of the five food groups from Composition of Foods of RDA. Multiple regression analysis was used to analyze the effects of household size and income based on the expenditure share on each food group. All statistical analyses were performed using SAS/ PC version 9.3. Results show that household socio- demographic characteristics have a strong influence on food purchasing, with the purchase of vegetables and fruit, and processed food and pre-packaged being particularly sensitive.

점진적 중도절단 방법 (progressive censoring scheme)상황에서 관측되는 시점의 자료들 사이에는 관측원의 실수 혹은 관측 기계의 오류로 인하여 또 다른 중도절단이 발생할 수 있어 다중 점진적 중도절단 방법 (multiply progressive censoring scheme) 이 새롭게 제안되었다. 본 논문은 다중 점진적 중도절단 방법 상황에서 하프 로지스틱분포의 척도 모수를 추정하였다. 이를 위해 최대우도추정량 (maximumm likelihood estimator)을 계산하였고, 테일러 급수 전개를 이용한 근사된 최대우도추정량 (approximate maximumm likelihood estimator)을 이용하여 하프 로지스틱분포의 척도 모수를 추정하였다. 또한, 다양한 다중 점진적 중도절단 상황에서 몬테카를로 모의실험을 실시하여 평균 제곱오차 및 편의를 이용하여 제안한 추정량들을 비교하였고, 사례 자료를 이용하여 제안한 추정량들을 계산하였다. Under progressive censoring scheme, some units can be failed between two points of observation with exact times of failure of these units unobserved. In this reason, multiply progressive censoring scheme was introduced. In this paper, we consider the maximum likelihood estimator of the scale parameter of the half-logistic distribution under a multiply progressive censoring scheme. And, the scale parameter of half logistic distribution is estimated by approximate maximum likelihood estimators that use Taylor series expansion. Monte Carlo simulations are conducted to compare the results among maximum likelihood estimator and approximate maximum likelihood estimators. A real data set based on the multiply progressive censoring scheme is also analyzed for illustrative purposes.

신미(1811) 통신사의 회화 활동과 19세기 전반의 한일 회화 관계 : 이의양筆 倣谷文晁山水圖를 중심으로
박성희(Park, Seonghee) 한국미술연구소 2015 美術史論壇 Vol.- No.41
Yi Uiyang(1768-?), a painter who accompanied Sinmi(1811)-Tongsinsa, painted landscape paintings in imitation of a painting by Tani Bunchō(1763-1840). And he stated that fact on his signature. Landscape Painting (Busan Museum) is assumed to be painted in 1811. This painting shows a typical style of Southern School, only using ink on a Japanese-made paper. From the late 18th century, Joseon intellectuals’ perception of Japan became relatively amicable. Influenced by this transition, Tongsinsa attendants in 1811 were able to emphasize with Bunchō’s paintings. This work should be a result of these particular circumstances. Moreover, Bunchō’s Gagakusai zukō (dated around 1812, Tahara Municipal Museum, Japan) is in the spotlight. Because there is a sketch which seems to be the original version of Landscape Painting. 7 years later in 1818, Yi Uiyang painted Summer Landscape (Sen-oku Hakuko Kan, Japan), which is very similar to Landscape Painting. The inscription was written by Kim Jeonghui, who had Bunchō’s paintings in his collection due to his close social relationship with Tongsinsa attendants in 1811. In the same year, Jin Dongik, who left the inscription on Landscape Painting, was sent to Tsushima domain as Munwihaeng. It should be related to the introduction of Summer Landscape to Japan. In 1825, this work was gifted to the Sumitomo family by Kojima Uzaemon, an officer of Tsushima domain. This can examine aspects of Korea-Japan exchanges of painting and roles of Tsushima domain after severance of Tongsinsa in the early 19th century. At the beginning of 19th century, the end of early modern Korea-Japan relations, Yi Uiyang painted landscape paintings in the style of a contemporary Japanese painter, Tani Bunchō. This fact is a good example to prove changes of Joseon intellectuals’ perception of Japan from the late 18th century to the early 19th century. Therefore, Yi Uiyang’s Landscape Paintings in Imitation of a Painting by Tani Bunchō can be considered a landmark case throughout history of Korea-Japan relations mediated by painting.

주체를 욕망한 낯선 결측치들 - <네버 렛 미 고>와 <공기인형>을 중심으로 -
박성희 ( Seonghee Park ) 한림대학교 일본학연구소 2021 翰林日本學 Vol.- No.39
본 논문은 마크 로마넥의 <네버 렛 미 고>(2010)와 고레에다 히로카즈의 <공기인형>(2009)을 대상으로 하여, 선행연구에서 간과하고 있는 ‘클론’과 ‘인형’이 주체를 욕망해가는 과정을 통해서 미디어가 SF라는 장르를 빌어서 전하고자 한 메시지가 무엇인지 고찰한다. 두 영화는 인간의 감정을 가지게 된 존재인 클론의 정체성에 대한 질문과 마음을 가져버린 인형이 바라보는 인간사의 외로움에 집중한다는 점에서 접근 방식의 차이는 있다. 그러나 원작이 있다는 점, 인간의 마음이나 영혼과 연결되어 인간 존재방식에 대한 궁극의 천착과 관련이 있다는 점, 포스트휴먼을 다루지만 미래사회나 기계화된 문명을 제시하지 않는다는 점, 포스트휴먼류이지만 지극히 인간적이라는 점, 디스토피아 문제를 반추해볼 소재라는 점, SF영화로 분류되기도 하고 성장영화의 얼개를 가지고는 있지만 흥미진진한 속도감도 영웅도 없다는 점 등을 공통분모로 들 수 있다. 이들이 묘사하는 ‘아류인간’의 당면한 문제가 인종차별, 성차별, 문화적 정체성, 소수자 문화 등에 대한 메타포임을 확인하고 그 분석과 비판을 종의 해체, 연의 해체, 낯선 결측치로 고찰한다. 주체를 가지게 된 포스트휴먼으로 인해 우리는 진정한 인간의 모습에 대한 회의와, 예술과 휴머니티에 대한 궁극의 천착과 타인(異種)을 이해하기위한 수용범위에 대하여 고민해 볼 수 있다. This thesis examines what message media is trying to convey through the genre of science fiction through the process of ‘clones' and 'dolls' lust for the subject which is overlooked in previous studies focusing on Kazuo Ishiguro's "Don't Let Me Go" (2005) and Koreida Hirokazu's "Air Doll" (2009). The two films have common characteristics although they differ in their approaches; one raises a question about the identity of the clone and the other focuses on the loneliness of human affairs seen by a doll with a heart. They also have common things: that they are based on original works and are related to Japan, that they deal with posthumans but do not present a future society or a mechanized civilization, that they are extremely humane although they belong to posthuman type, that they deal with the subject to reflect on the problem of dystopia, and that they are classified as sci-fi movies and have frameworks of growth novels without exciting sense of speed and heroes. We confirmed that the immediate problems of the “pseudo-human” they describe are a metaphor for racism, gender discrimination, cultural identity, and minority culture and examined the analysis and criticism through the dissolution of relationship, dissolution of species and unfamiliar missing values. Because of the posthuman who came to have subject, we were able to contemplate the skepticism of the true human form, the ultimate indulgence in art and humanity, and the scope of acceptance to understand others.
