Tobacco mosaic virus (TMV), TMV-common strain, causes severe damage at growth, yield and leaf quality on flue-cured tobacco in Korea. Controlling TMV outbreak with cultivating practices and chemicals are limited, thus, the best way would be developing TMV resistant variety. A new flue-cured hybrid, KF118, was developed from a cross of maternal parent MSTC175 and TC853 at the Agro-tech. Research Group, KT&G Central Research Institute. KF118 exhibited more vigorous growth characteristics in early stage than that of NC82, standard variety in Korea, while other characters were favorable to those of NC82, It is highly resistant to TMV and bacterial wilt(Ral-stonia solanacerum), and black shank(phytophthora parasitica var. nicotianae) is comparable to that of NC82. It should adapt well to the flue-cured production area, and can reduce premature flowering under unfavorable weather conditions. Yield of KF118 is 1 to 2% higher, and leaf quality is 4% higher than NC82. Fl hybrid, KF118, met acceptable standards for chemical and physical characteristics of cured leaf, and ranked high in good smoking taste by panel members in KT&G.

연초 (Nicotiana tabacum L.) 감자바이러스Y 저항성 품종육성 I. 황색종 품종 McNair30의 감자바이러스Y 저항성유전

정윤화,정석훈,금완수,최상주,이승철 한국연초학회 1984 한국연초학회지 Vol.6 No.2

To classify the inheritance of resistance to potato virus Y, crosses between susceptible flue-cured tobacco variety NC 95 and resistant variety McNair 30 were conducted. The parents, $F_1$ plants, $F_2$ populations, and haploid plants derived from anthers of $F_1$ plants were screened for a resistance of two potato virus Y strains (PVY-VB and PVY-VN) isolated in Korea. The Chi-square values for the $F_3$ populations and haploids of $F_1$ fitted 1 :3 and 1 :1 ratios of resistant to susceptible for two strains, respectively. Therefore, it was found that the resistance of McNair 30 for the potato virus Y was controlled by a single recessive gene. Moreover the resistance to two strains screened was inherited dependently.

The present study was conducted to compare the relative efficiency of two different haploid breeding methods in tobacco varietal development. A single F t hybrid plant from cross of two flue-cured cultivars of Nicotiana tabacum L., Bright Yellow4(BY4) and NC 95, was used to develop the 30 dihaploid lines by anther culture(F1-ADH) and maternally-derived doubled haploid utilizing Nicotiana africana(F1-MDH), respectively. As compared with mid-parent, ADH lines showed increasing in number of leaves, delaying in days to flower and narrowing in leaf width. However, no significant differences in the other characters investigated were recognized. MDH lines also showed narrow leaf width, while no significant differences in the other characters were observed. The variations of the characters investigated were generally greater in ADH than MDH lines. MDH lines had higher plant height and shorter days to flower than ADH lines, while other characters did not show remarkable differences. The degree of heritability for each of the characters observed between ADH and MDH was almost the same. The characters showing high heritability value were plant height, leaf number, days to flower, and yield, while those showing relatively low value were leaf length, leaf width, and total alkaloid content. Predicted gains from selection for increased yield were calculated for both populations(F1-ADH, F1-MDH) and correlated responses associated with selection for yield were estimated. Plant height, leaf width, days to flower, percent reducing sugar and disease resistance would be expected to improve with selection for yield much faster in the MDH population than in the ADH.

The present study was conducted to compare the relative efficiency of four different breeding methods in tobacco varietal development. A single Fl hybrid plant from cross of two flue-cured cultivars of Nicotiana tabacum L Bright Yellow 4(BY4) and NC95, was selfed. F2population above cross was screened for resistance against bacterial wilt caused by Pseudommonas solanacearum E.F.Smith under the naturally infested field conditions, and the 30 lines were developed from F2 individual plant by anther culture (ADH), maternal method utilizing Nicotiana afpicana (MDH), single- seed descent(SSD) and Bulk breeding method, respectively. All characters except content of total alkaloids of ADH and MDH which wore bred by haploid methods reduced more than that of lines bred by conventional methods(SSD & Bulk) : however, the yields were 8% lower than other lines. The total alkaloid content of ADH was higher than that of MDH, and yield was reduced about 4n even though the number of leaf was identical with the MDH. All other characters of ADH were also reduced significantly. In the lines bred by conventional methods, population developed by SSD showed significantly wider leaf width, shorter plant height, later days to flower, and lower in percent reducing sugar than those by Bulk. The populations derived from haploid method showed greater phenotypic variance and wider range of variation than conventionally developed ones. The results obtained indicate that selection will provide a significantly greater genetic gain for leaf number and leaf length in the ADU and MDH populations, and for plant height and days to flower in the SSD and Bulk populations.

연초의 이배체와 반수체의 저온단일 감응성 비교

정윤화,금완수 한국연초학회 1994 한국연초학회지 Vol.16 No.2

Response of two ploidy levels to cool temperature and short day treatment were investigated under controlled conditione of Phytotron. The haploid and diploid of seven genotypes were started and grown to the 8- leaf stage in the greenhouse. They were treated during 15 and 20 days to 8- hour photoperiods at 18$^{\circ}C$ in controlled - environmental room to induce premature flowering, respectively. Diploid plants of seven genotypes flower later than their haploid plants at 20 days treatment. But under 15 days treatment, diploid plants of NC82, Hicks, BY4, NC2326 and Coker86 were not different from their haploid plants for days to flower. Diploid plants of seven genotypes developed the same number of leaves as their haploid plants at 20 days treatment. Under 15 days treatment, diploid plants of Coker347 and NC95 developed more leaves per plant than their haploid plants. Correlation coefficient between the ranks of leaves per plant of seven genotypes at two ploidy levels was 0.964 and 0.929 at 15 and 20 days treatment, respectively.

WHO 가이드 원칙을 통해 살펴본 한국의 커뮤니티 케어 시범사업과 일본, 스웨덴의 정책 비교

정윤화,이동현 한국보건사회연구원 2023 保健社會硏究 Vol.43 No.1

This study compared the community care policies of Korea, Japan, and Sweden based on the WHO global strategy. Each country's community care policy was rated as appropriate, insufficient, or absent depending on the degree of its conformity to the “Guiding Principles for the Decade of Healthy Ageing.” In addition, descriptions of related contents were provided. Our analysis found that the policy contents of “Interconnected and indivisible”, “Inclusive”, “Multistakeholder partnerships”, “Leaving no one behind”, “Equity”, “Commitment”, and “Do no harm” were insufficient to support community-based integrated care. Regarding the strategy of “Intergenerational solidarity”, there was no relevant policy content. The directions for improvement are as follows: “Reinforcement of local health”, “Expansion of selective targets for the vulnerable”, “Clarification of scope of work”, “Expansion of 24-hour or non-face-to-face operation”, “Prevention of blind spots for benefits”, “Preparation of generational exchange”, “Preparation of grounding legislation”, and “Securing stable financial resources.” This study was intended to identify improvement directions for the Community Integrated Care Leading Project and help it become more broadly applied in the future. 본 연구는 한국, 일본, 스웨덴의 커뮤니티 케어 정책을 WHO 가이드 원칙에 기준하여 비교했다. 각 국가의 커뮤니티 케어 정책이 Decade of Healthy Ageing을 위한 가이드 원칙에 부합하는지 여부를 적합, 미흡, 부재로 판단했고, 관련 내용을 기술했다. 분석 결과, 한국의 지역사회 통합돌봄 정책은 ‘상호 연결성과 불가분성’, ‘포괄성’, ‘다중이해관계자 파트너십’, ‘비배제성’, ‘형평성’, ‘지속성’, ‘무해성’에 미흡했고, ‘세대 간 연대’에 대한 내용이 부재했다. 이에 대한 개선 방향으로는 ‘지역 보건 강화’, ‘취약계층의 선별적 대상 확대’, ‘업무 범위 명확화’, ‘24시간・비대면 운영 확대’, ‘수혜 사각지대 방지’, ‘세대 교류 마련’, ‘근거 법안 마련’, ‘안정적 재원 확보’ 등을 제시했다. 본 연구를 통해 우리나라 커뮤니티 케어의 개선 방향을 모색하고 향후 건전한 보편화에 기여하고자 한다.

19세기 중엽 寒洲 李震相의 現實認識과 國家體制改革論

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.
