The rice blast disease caused by of Magnaporthe oryzae is one of the most destructive diseases of rice. By the microarray analysis, we profiled expression changes of genes during conidiation and found out many putative genes that are up-regulated. Among those, we first selected MGG_06399 encoding a dual-specificity tyrosine-regulated protein kinase (DYRK), homologous to YAK1 in yeast. To investigate functional roles of MoYAK1, We made ${\Delta}Moyak1$ mutants by homology dependent gene replacement. The deletion mutant showed a remarkable reduction in conidiation and produced abnormally shaped conidia smaller than those of wild type. The conidia form ${\Delta}Moyak1$ were able to develop a germ tube, but failed to form apppressoria on a hydrophobic coverslip. The ${\Delta}Moyak1$ formed appressria on a hydrophobic cover slip when exogenous cAMP was induced, but the appressoria shape was abnormal. The ${\Delta}Moyak1$ also formed appressoria abberent in shape on onion epidermis and rice sheaths and failed to penetrate the surface of the plants. These data indicate that MoYAK1 is associated with cAMP/PKA pathway and important for conidiation, appressorial formation and pathogenic development in Magnaporthe oryzae. Detailed characterization of MoYAK1 will be presented.

Ryuseo(類書) is a type of traditional books and seems like today's encyclopedia. For compilation of this book, the contents with good ideas and the improvement in method of editing are very important. The process of development, basic form, reception and transformation, the method of succession in today were investigated with the traditional Ryuseo through this study. In Korea, the publishing of this book in the beginning was just republishing of Chinese Ryuseo. During the reign of king Sunjo of Chosun dynasty, Ryuseo for Korean, "Daedongeunbugunok(大東韻府群玉)" was published. Also the basic form of Ryuseo had to be changed in this period. Kimyuk increased practical use of this book by summarizing "Samunryuchui(事文類聚)". The first complete Korean Ryuseo was "Kosachalyo(故事撮要)" that was published in 1554, king Myungjong. In the book was included contents about diplomacy and daily life by Eosukkwun. In 1771, king Youngjo, "Kosashinseo(故事新書)" was published. It had more information about actual life than Kosachalyo. Ryuseo should be considered with two things when it is read by modern readers. One is the development of material for study and another is to ensure the readers. So Ryuseo could be a good basic material for developing contents of internet. Reproduction of this book by new one should be considered with increasing its function. Because reforming classical material by digital one is necessary for daily life in today.

The Dengue virus M protein is a 75 amino acid polypeptide with two helical transmembranes (TM). The TM domain oligomerizes to form an ion channel, facilitating viral release from the host cells. The M protein has a critical role in the virus entry and life cycle, making it a potent drug target. The oligomerization of the monomeric protein was studied using ab initio modeling and molecular dynamics simulation in an implicit membrane environment. The representative structures obtained showed pentamer as the most stable oligomeric state, resembling an ion channel. Glutamic acid, threonine, serine, tryptophan, alanine, isoleucine form the pore-lining residues of the pentameric channel, conferring an overall negative charge to the channel with approximate length of 51.9 Å. Residue interaction analysis for M protein shows that Ala94, Leu95, Ser112, Glu124, and Phe155 are the central hub residues representing the physicochemical interactions between domains. The virtual screening with 165 different ion channel inhibitors from the ion channel library shows monovalent ion channel blockers, namely lumacaftor, glipizide, gliquidone, glisoxepide, and azelnidipine to be the inhibitors with high docking scores. Understanding the three-dimensional structure of M protein will help design therapeutics and vaccines for Dengue infection.

This study examines ways of housing usage and aspects of resident's life based on the representative traditional house "UNJORU" as time passed. In other words, it explains how the traditional life has changed. these days compared to late Joseon dynasty. It also explains how the meaning of the place changed by life style change and the aspect have changed in women's perspective. This is for restoring the time period that the life dairy was recorded later time period. We can trust Mrs. Lee who is the eldest resident of them at the present in UNJORU. The method of study proceeded by interview format. It is classified a meal place and a folk-beliefs the daily life the funeral rites non-daily life, such as in this process, was conducted to understand the consciousness and life form at the time of residents. As a result, Ryu's family life style has preferred a more modern life style than traditional life style by time as well as society changes. Through this research, It was possible to analyze how the external formality of traditional house has kept but internal formality has changed over time.

Recognizing the importance of the multi-purpose management of natural deciduous forest, this study was carried out to implement the partial cutting for stand regulation to examine agroforestry practice as well as other concurrent forest resource production, and to investigate the changes in stand characteristics and understory vegetation in a silvopasture practiced natural deciduous stand in the Research Forest of Kangwon National University, Korea. Three different partial cutting intensities (68.1%, 48.6%, and control) were performed in the unmanaged natural deciduous stand in order to improve the growing condition, especially light condition, for introducing some commercial herbaceous plants on the forest floor to establish agroforestry and/or silvopastoral system. Dominated by Quercus varibilis Blume (50.5%) and Quercus dentata Thum. ex Murray (42.6%), eight tree species were composed of the study forest, including poles of Pinus desiflora Siebold & Zucc and sapling of Pinus Koraiensis Siebold & Zucc. The total of 87 (13 tree species, 12 shrub species, 58 herbaceous species, and 4 woody climbers) vascular plant species were observed in study site after partial cutting treatments, while that of before partial cutting was 53 species (14 tree species, 8 shrubs species, 30 herbaceous species, and 1 woody climbers). The proportion of life form spectra in plot B was Mi (28.4%)-Na (23.0%)-Ge (17.5%)-Ch (10.8%)-He (9.5%)-MM (6.7%)-Th (4.1%). No statistically significant differences were observed in changes of life form spectra from before to after partial cutting treatment and among partial cutting gradients in this study. Partial cutting and scratching for forage sowing made plants invade easily on the forest floor, and light partial cutting (LPC) plot (500 stems/ha) had much higher number of undersory species than those of heavy partial cutting (HPC) plot (310 stems/ha) and control plot (1,270 stems/ha).

학교교육에서 확률의 독립사건의 정의 P(B | A)=P(B)가 직관적으로 설명할 수 없고 실생활과 다른 개념으로 잘 못 판단되어 질 수 있는 원인을 분석하고, 확률의 독립사건의 전형적인 문제와 정리들을 이용하여 실생활 개념과 정확하게 일치하고 직관적으로 설명 가능하다는 사실을 '구술형식'으로 논증한다. 확률과 통계 단원은 물리와 유사한 자연현상과 실생활에 더 밀접한 학문이므로 '수리식'을 보완한 '구술형식'의 보급은 불가피하다. 따라서 확률교육에서 오랜 기간 지속되어 온 '수리식'을 보완하여 '수리식'이 갖는 의미를 직관적으로 쉽게 이해 가능한 새로운 개념 습득 방법인 '구술형식'으로 설명할 필요성과 가능성을 제시한다. 본 논문을 통하여 그동안 학교교육이 확률의 독립사건 정의의 '수리식' 의미를 파악하지 못하여 확률교육의 맥이 막혀 있었다면 확률교육의 흐름에 새로운 지평을 여는 커다란 파급효과를 기대할 수 있다.

The objective of this study was to provide basic data for the conservation of wetland ecosystems in the Civilian Control Zone and the management of Yongyangbo wetlands in South Korea. Yongyangbo wetlands have been designated as protected areas. A field survey was conducted across five sessions between April 2019 and August of 2019. A total of 248 taxa were identified during the survey, including 72 families, 163 genera, 230 species, 4 subspecies, and 14 varieties. Their life-forms were Th (therophytes) - R₅ (non-clonal form) - D₄ (clitochores) - e (erect form), with a disturbance index of 33.8%. Three taxa of rare plants were detected: Silene capitata Kom. and Polygonatum stenophyllum Maxim. known to be endangered species, and Aristolochia contorta Bunge, a least-concern species. S. capitata is a legally protected species designated as a Class II endangered species in South Korea. A total of 26 taxa of naturalized plants were observed, with a naturalization index of 10.5%. There was one endemic plant taxon (Salix koriyanagi Kimura ex Goerz). In terms of floristic target species, there was one taxon in class V, one taxon in Class IV, three taxa in Class III, five taxa in Class II, and seven taxa in Class I. Three invasive alien species (Ambrosia trifida L., Ambrosia artemisiifolia L., and Humulus japonicus Siebold & Zucc) were observed. For continuous conservation of Yongyangbo Wetlands, it is necessary to remove invasive alien plants and block the inflow of non-point pollutants.

Purpose: This study was conducted to identify the level of quality of family life, parental locus of control, and parental sense of competence, and to elucidate factors that influence family quality of life in the mothers of children with Attention Deficit/Hyperactive Disorder (ADHD). Method: A convenient sample of mothers from 6 child psychiatric clinics was used in this cross-sectional survey design. Questionnaires used for data collection included the following scales: Family Quality of Life, Parental Locus of Control-Short Form Revised, Parental Sense of Competence. Results: The level of family quality of life was mid-range. A positive relationship was found between Family Quality of Life and the research variables. The significant predictors of family quality of life were parental locus of control, parental sense of competence, and duration of medication and these variables accounted for 21.8% of the variance in family quality of life. Conclusions: These results indicate that family quality of life is an important factor which health care provider should assess and evaluate for children with ADHD and their families. The results of this study suggest that family quality of life is an important link with parental sense of competence and parental locus of control.
