Flavonoids have a variety of biological functions including UV protectant, antioxidant, allelopathy and auxin transport inhibitor in plants. In addition, favonoids are implicated in defense response against pathogens. In this study, we found that kaempferol, a kind of favonol, induces bacterial pathogen resistance. In addition, we identifed the signaling pathway to explain how kaempferol can induce pathogen resistance in Arabidopsis. We showed that kaempferol upregulates the transcription of two pathogenesis-related (PR) genes. Interestingly, the monomerization and nuclear translocation of NPR1, a key regulator of PR gene expression, was induced by kaempferol through the accumulation of salicylic acid (SA). Furthermore, we found that the kaempferol-induced monomerization of NPR1 is mediated by the activation of MPK3 and MPK6. Taken together, this study suggests that kaempferol induces pathogen resistance by both SA and MPK-dependent signaling pathways in Arabidopsis.

본 연구는 교육부의 ‘2022 개정 교육과정 추진 계획’의 발표와 관련하여, 2022 개정 교육과정에 따른 초·중등 교과용도서의 국·검·인정 발행 체제 구분을 위한 합리적인 기준을 구안 및 제시하기 위해 수행되었다. 이를 위해 본 연구에서는 선행 연구와 최근 발표된 교과용도서 구분 고시 등을 참조하여 국·검·인정 발행 체제 및 구분 고시의 특성을 탐색하였으며, 교과용도서 국·검·인정 구분 준거(안)을 ‘기본 고려 사항’과 ‘구분 기준’으로 나누어 개발‧제시하고, 구분 준거를 활용할 수 있는 방안을 제안하였다. 제시한 교과용도서 구분 준거(안)은 교과용도서 자율화‧다양화 정책에 부응하는 창의적이고 질 높은 교과용도서 개발을 위한 기본적인 토대라고 할 수 있으며, 교과용도서 구분 심의와 교육부, 검정 심사 기관, 시·도 교육청 등의 교과용도서 개발 및 보급 관련 업무 계획을 수립하는 데 활용될 예정이다. 이를 통해, 사회의 변화와 요구 사항을 반영한 교과용도서의 발행 및 학교 현장 적용이 가능하고, 학습자의 교과용도서 선택권이 확대될 것으로 판단된다. In relation to the announcement of the 2022 Revised National Curriculum Development Plan, this study proposes reliable criteria to classify elementary and secondary school curriculum books based on the 2022 Revised National Curriculum under government-copyrighted, government-authorized, and government-approved publishing systems. Previous curriculum book categorization notices and relevant studies were analyzed to explore the characteristics of these systems and notices. Based on the analysis, the study proposes ‘basic considerations,’categorization criteria’, and suggestions for applying categorization criteria. These categorization criteria can serve as a foundation for the development of creative and high-quality curriculum books that are commensurate with the policy of curriculum book autonomy and diversification. The criteria can also be used for establishing work plans for the development and dissemination of curriculum books by the Ministry of Education, textbook authorization institutions, and educational boards of cities and provinces. It is expected that social change and demand will be more closely reflected in curriculum books, and leaners’choices for curriculum books will be expanded.

Markov Chain 모형을 이용한 수도권 인구분포예측에 관한 연구

  The distribution of Population across territory plays a very important role as a leading indicator in various urban planning and its implementation. Inaccurate prediction of population distribution will bring about loss of the rationality that may rooted in a plan or an idea not only for the concerning cities but also for their adjacent metropolitan areas. On the basis of understanding the importance of the prediction, this paper reviews the characteristics of the population in Seoul Metropolitan area. The study is undertaken by analyzing migration data among Seoul Metropolitan Area"s administrative districts, which shows that the change of population movement is a primary factor dominating changes in population distribution. The analytical method employs Markov Chain Model, which is one of the popular methods for population analysis home and abroad. The period of the analysis in this study covers five years from 2001 to 2005. The target area is subdivided into Cities(shi), Counties(gun), and Wards(gu), and analyzed by its administrative subdivisions. In the analysis of this model the correlation coefficient of the predicted result is from 0.01 to 0.999, which means that this model has higher predictability.

Cases of sector retinitis pigmentosa, a variant of typical retinitis pigmentosa, are seen infrequently. It is chracterized by pigmentary changes occuring in one quadrant of the retina, visual field defects usually only in the region of retinal pigmentation, and minimal or no extention of retinal area involved with time. The authors experienced a 45-year-old male patient who suffered from bilateral symmetric sector retinitis pigmentosa, residing in inferior quadrants, producing corresponding defect in the superior visual field.

Deep Blue LED 광원과 형광체를 이용한 초고연색 백색 인공태양광 LED 소자의 개발

Currently, yellow phosphor of Y3Al5O12:Ce3+ (YAG:Ce) fluorescent material is applied to a 450~480nm blue LED light source to implement a white LED device and it has a simple structure, can obtain sufficient luminance, and is economical. However, in this method, in terms of spectrum analysis, it is difficult to mass-produce white LEDs having the same color coordinates due to color separation cause by the wide wavelength gap between blue and yellow band. There is a disadvantage that it is difficult to control optical properties such as color stability and color rendering. In addition, this method does not emit purple light in the range of 380 to 420nm, so it is white without purple color that can not implement the spectrum of the entire visible light spectrum as like sunlight. Because of this, it is difficult to implement a color rendering index(CRI) of 90 or higher, and natural light characteristics such as sunlight can not be expected. For this, need for a method of implementing sunlight with one LED by using a method of combining phosphors with one light source, rather than a method of combining red, blue, and yellow LEDs. Using this method, the characteristics of an artificial sunlight LED device with a spectrum similar to that of sunlight were demonstrated by implementing LED devices of various color temperatures with high color rendering by injecting phosphors intoa 405nm deep blue LED light source. In order to find the spectrum closest to sunlight, different combinations of phosphors were repeatedly fabricated and tested. In addition, reliability and mass productivity were verified through temperature and humiditytests and ink penetration tests.

구한말과 일제 강점기 지문학(地文學)의 도입 및 변화에 대한 연구

구한말 및 일제 강점기에 ‘지문’은 보편적인 교육을 목적으로 하는 중등 지리 과목 중 가장 심화된 내용을 담고 있던 계통지리 과목이다. 본 연구에서는 먼저, 해방 직후 중등 지리 과목인 ‘자연환경과 인류생활’의 교수요목과 구한말 및 일제 강점기 초기의 지문학 교과서 내용 간 유사성을 확인하였다. 다음으로 ‘지문’이 등장하고 사라지는 과정을 대한제국과 조선총독부의 교육 관련 각종 법령 및 이에 포함된 중등교육 학과 과정의 변화를 중심으로 살펴보았다. 이 과정에서 시대적 상황을 고려하여, 해당 시기 일본 학계의 지리학 정의에 관한 논의와 문부성의 교수요목을 비롯한 법령의 변화상도 함께 다루었다. 지문학 관련 내용은 1910년 무렵 일본의 중등학교 지리과 교수요목에서 ‘지문’이라는 과목명이 사라진 후에도, 인문지리가 더해진 ‘지리학통론’이나 ‘지리개설’ 등의 과목을 통해 고유의 자연지리적 특성을 유지해 왔으며, 이와 같은 특성은 해방 직후의 중등학교 교수요목으로 이어진다고 할 수 있다.
