반수체 육종법을 이용한 잎담배 세균성마름병 저항성 개체 선발의 효율성 비교
정윤화 한국연초학회 1993 한국연초학회지 Vol.15 No.2
The present study was conducted to compare the efficiency of individual plant selection for resistance to bacterial wilt with 30 dihaploid lines derived by anther culture and Nicotiana africana method in Fl and F2 generation from a cross between Bright Yellow 4 (BY4) and NC95. F2 dihaploid lines were selected from bacterial wilt disease resistant plants screened under the naturally infested filed conditions. The populations of FB - ADH and FB MDH derived from F2 individual plants with bacterial wilt resistance showed higher resistance to the disease than the populations of Fl - ADH and Fl - MDH, respectively, and no difference for the disease resistance appeared by the haploid deriving method within a generation.

연초 종자생산의 기초자료를 얻기 위하여 임성품종과 웅성불임 품종을 공시하여 격리거리 및 이식시기에 따른 자연교잡율을 조사하였다. 1. 임성품종간의 인접재배시 자연교잡율은 평균 1.6%이었고 0.9~2.5%범위로 나타났다. 2. 임성품종과 웅성불임 게통의 인접재배시 자연교잡율은 29%로 임성품종에 비하여 현저히 높게 나타났다. 3. 이식시기따른 자연교잡율은 4월20일 이식한 처리구가 5월 5일 및 5월20일 이식한 처리구보다 현저히 높았다. 4. 격리거리에 따른 자연교잡율은 격리거리가 멀수록 낮았고 300m 격리구에서도 자연교잡이 0.8%로 나타났다. This experiment was conducted to investigate the amount of natural crossing at varying isolation distance and various transplanting time in tobacco. Normal variety and male sterile line showed an average of 1. 6 and 29% natural crossing in the adjacent plantings, respectively. The natural crossing was highest in the adjacent planting, as expected, and less at the farther distance from pollinator plants. Plants transplanted in April 20th were higher in natural crossing than those of other transplanting time.

Varietal response to cool temperature(18$^{\circ}C$) and short (8hr.)-day treatment were investigated under controlled conditions of Phytotron in the Suwon Agronomy Experiment Station. Five flue-cured and one burley tobacco varieties (Nicotiana tabacum L.) were used, and the length of treatment ranging from 8 to 32 days at 3-day intervals and also includes continuous treatment up to the plants were flowered. The days to flower decreased significantly than the no treatment when the length of treatment was 11 to 14 days for the varieties NC82, Br.21 and NC22NF, and 17 to 26 days for SPG-28, Mc.944 and TC499, respectively. And also the number of leaves decreased significantly than the no treatment when the length of treatment was 8 days for NC22NF, 11days for NC82 and Br.21, 14 days for Mc.944, and 17 days for SPG-28 and TC499, respectively. The maximum decreasing ratio of the leaf number by the cool temperature and short-day treatment were 47.7 to 58.5% for NC82, Br.21 and NC22NF, and 38.9% for Mc.944, 33.4% for SPG-28 and 29.0% for TC499, respectively.

정윤화 조선시대사학회 2016 朝鮮時代史學報 Vol.79 No.-
Hanju Lee, Jin-sang is a Confucian scholar who represents Yeongnam Confucianism in the last half of the 19th century by succeeding Lee Hwang’s theory critically and develop it into the Chen Yi’s theory. Meanwhile, the Joseon Dynasty faced a new crisis called riots and the western powers’ invasion inside and out in the middle of the 19th century. Based on this historical backdrop, Lee, Jinsang wrote Myochungrok which aims at stability of the local governments and reinforcement of national defense through a revolutionary improvement over the overall state systems. As for the direction of the system reorganization planned by Lee, Jinsang, he first tried to organize the land system with Gyeongmyo law and expand a nation’s purse through reorganization of the three administrations Concretely, he organized income items including Yeokjeon, Hojeon, and Japse by breaking all the miscellaneous nominal lists of real-estate taxes imposed on land then and simplifying them to be the taxes of 1/10. In the reorganization of the local systems, he tried to improve local finance by reducing county system drastically and the expenses. Next, he tried to wipe out corruption and public harm and fulfill his duties for stability of local society by improving local governors and petty official’s treatment. The reorganization of the educational system focuses on expansion of public education led by the state. And he suggested the election system. as a measure to overcome problems of the existing system to select talented persons. In the reorganization of the military system, a reform plan is suggested by the two ways of the organization of the military and military service. In the reorganization of the military organization, he built the prompt command system and at the same time, made military commanders from Muban take full charge of the military as Oyeong by Naeyeong, the supreme military authorities, and the central Command was installed in the central area and the existing 502 local military agencies were drastically reduced to be 293 places in the local areas. As for the military service, he suggested the plan that national finance allocates the whole military expenses instead of breaking the institution of paying cotton cloth and Employment of soldiers by payment and military assistance is maintained as each village selected 20 strong young men. Especially, he tried to make the military seasoned troops by selecting all the soldiers by tests and paying salaries to all of them. However, Lee, Jin-sang’s reform plan of the systems has the limit that it was not submitted, reviewed, and adopted in the Joseon government. Nevertheless, it is meaningful in that he agonized about it focusing on preparing the reform plan which is highly feasible. Especially, his reform plan has the historical significance as the indicator which shows that the reform theory of the 19th centry was changed from Gyunsanron by the reformers who conventionally argued a revolution of landownership to Gyunsegyunburon which focused on fiancial expansion and distribution through the reorganization of the taxation system. 한주 이진상은 이황의 학설을 비판적으로 계승하여 성즉리설로 발전시킨 19세기 후반 영남 유학을 대표하는 성리학자이다. 한편, 19세기 중엽 조선은 나라 안팎으로 민란과 서구세력의 침범이라는 새로운 위기에 직면하고 있었다. 이진상은 이러한 시대적 배경을 바탕으로 국가제도 전반에 걸친 일대 개혁을 통해 지방사회의 안정과 국방강화를 목표로 하는 『畝忠錄』을 저술하였다. 이진상이 구상한 제도개편의 방향은 제일 먼저 頃畝法으로 토지제도를 정비하고, 부세제도는 삼정체제의 개편을 통하여 국가재원을 확충하고자 하였다. 구체적으로는 당시 토지에 부과되었던 잡다한 토지세 명목을 모두 혁파하고 1/10세로 단일화 하는 것을 골자로 하여 그 외 役錢․戶錢․雜稅 등으로 수입항목을 정비하였다. 지방제도 개편에서는 郡縣制를 대폭 감축함으로써 경비를 절감하여 지방재정을 개선하고자 하였다. 다음으로 지방 수령과 이서의 처우를 개선함으로써 지방사회의 안정을 위한 소임을 다하도록 하였다. 교육제도의 개편은 국가가 주도하는 공교육의 확대를 골자로 한다. 또한 그는 종래 인재선발제도의 문제점을 극복하기 위한 방편으로 選擧制를 제시하였다. 군사제도 개편에서는 군사편제와 軍役의 두 방향에서 개혁안을 제시하였다. 군사편제 개편은 중앙에서는 최고군령기관인 內營과 중앙군으로 五營을 설치하고, 지방에서는 기존 502개소에 달했던 지방군사기관을 293개소로 대폭 축소 정비하여 신속한 지휘명령체계를 구축하는 동시에 군사지휘관은 武班출신 지휘관이 전담하게 하였다. 군역에서는 納布制와 군사 雇立制를 혁파하는 대신에 국가재정에서 일체의 군사비를 배정하고 각 里에서 20인씩 장정을 선발하여 군사자원을 유지하는 방안을 제시하였다. 특히 모든 군사는 試取를 통해 선발하고 전원 급료를 지급하여 군대를 정예화하고자 하였다. 그러나 이진상의 제도개혁안은 조선정부에 제출되어 검토되거나 채택되지 못한 한계점이 있다. 그럼에도 불구하고 그는 실현가능성이 높은 개혁방안의 마련에 역점을 두고 고심했다는 점에서 의미가 있다. 특히 그의 개혁방안은 19세기 개혁론의 추이가 토지소유관계의 변혁을 주장하였던 개혁론자들의 均産論에서, 부세제도 개편을 통한 재원의 확충과 분배에 초점을 맞추는 均稅均賦論으로 변화하는 양상을 보여주는 지표로서 역사적 의미를 지니고 있다고 하겠다.

Background/Aims: Among diffuse large B cell lymphoma (DLBCL) patients, determining the appropriate dose and chemotherapy schedule to balance toxicity and efficacy is harder in elderly than in younger patients. Moreover, there are no currently available clinical factors that consistently identify patients who are unfit to receive chemotherapy. Therefore, the clinical characteristics and outcomes of elderly patients with DLBCL and the causes of treatment-related death were investigated in this study. Methods: The clinical characteristics and outcomes of 44 elderly (≥ 70 years of age) patients diagnosed with DLBCL between January 2005 and June 2013 were evaluated. Variable clinical data along with the response rate, overall survival (OS), and causes of treatment-related death or treatment interruption were investigated. Results: The median OS was 18.6 months, and 19 patients completed curative treatment. The mean average relative dose intensity of adriamycin in patients who completed chemotherapy was 0.617, and of these patients, 16 achieved complete remission. Chemotherapy incompletion, infectious complications, extranodal involvement, high lactate dehydrogenase, poor performance status, and low albumin level at diagnosis were related to a shorter OS. However, multivariate analysis revealed that only infections and chemotherapy incompletion were significantly related to poor prognosis. The most common cause of treatment-related death was infection, and patients who had experienced infectious complications tended to have lower albumin levels than those of patients without such complications. Conclusions: In the treatment of elderly lymphoma patients, the dose intensity of adriamycin is not as important as it is in young patients. However, in elderly patients, infections are particularly dangerous, especially in patients with low albumin levels.
