  • Plant viruses are among the important pathogens that cause severe crop losses. The most efficient method to control viral diseases is currently to use virus resistant crops. In order to develop the virus resistant crops, a detailed understanding of the molecular interactions between viral and host proteins is necessary. Recessive resistance to a pathogen can be conferred when plant genes essential in the life cycle of a pathogens are deficient, while dominant resistance is mediated by host resistance (R) genes specifically interacting with effector proteins of pathogens. Thus, recessive resistance usually works more stably and broadly than dominant resistance. While most of the recessive resistance genes have so far been identified by forward genetic approaches, recent advances in genome editing technologies including CRISPR/Cas9 have increased interest in using these technologies as reverse genetic tools to engineer plant genes to confer recessive resistance. This review summarizes currently identified recessive resistance genes and introduces reverse genetic approaches to identify host interacting partner proteins of viral proteins and to evaluate the identified genes as genetic resources of recessive resistance. We further discuss recent advances in various precise genome editing technologies and how to apply these technologies to engineer plant immunity.

  • 최근 국내 과학기술분야 학회에서는 발행 학술지를 세계적인 학술지로 등재하고자 하는 노력이 증가하고 있다. 이에 따라, 해외연구자들을 학술지 편집위원으로 참여 시키고 많은 해외 연구자들이 자체 학술지에 논문을 많이 투고하도록 독려하고 있다. 해외 연구자들간에 이메일로 투고 심사를 처리하고 심사 총평을 작성하는 논문투고심사 프로세스는 심사 이력이 관리도 안 될 뿐만 아니라 논문투고 심사 진행 상황을 알 수 없음으로 인한 이용자의 불편함, 시간적 비효율성 등의 많은 단점이 있다. 이에 KISTI는 해외 연구자들이 학술지 생산을 위한 학술활동 전 과정에 참여할 수 있도록 하고자, 학술지를 체계적으로 운영하고 투명한 상호심사(Peer Review) 과정을 포함하는 학술지 전자 출판과정을 온라인으로 처리하고 모든 메뉴 용어를 국제적인 수준의 영어로 기술한 영문 Article Contribution Management System(ACOMS Ver. 4.0)를 개발하였다. 영문ACOMS는 기존 국문 ACOMS와 달리, 학술지 홈페이지를 포함하고 있으며, 저자와 편집위원 혹은 저자와 판사 간의 온라인 논문 교정 프로세스가 들어가 있다. 영문 ACOMS는 2012년 현재에도 국제적인 시스템으로 거듭나기 위해 지속적인 기능개선을 추진하고 있다. 개발된 영문 ACOMS 기능에 대해 살펴보고, 향후 개선방안에 대해 기술한다.

  • Spectroradiometers have recently been drawing great attention in earth observing communities for its capability for obtaining target's quantitative properties. In particular, light-weighted multispectral cameras are gaining popularity in many field domains, as being utilized on UAV's. Despite the importance of the radiometric accuracy, studies are scarce on the performance of the inexpensive multispectral camera sensors that have various applications in agricultural, vegetation, and water quality analysis. This study conducted assessment of radiometric accuracy for MicaSense RedEdge-MX multispectral camera, by comparing the radiometric data with an independent hyperspectral sensor having NIST-traceable calibration quality. The comaprison showed that radiance from RedEdge-MX is lower than that of TriOS RAMSES by 5 to 16% depending on the bands, and the irradiance from RedEdge-MX is also lower than RAMSES by 1~20%. The correction coefficients for RedEdge-MX alculated through the 1-st and the 3-rd order regression analysis were presented as a result of the study.

  • The purpose of Emergency Medical System(EMS) is what a patient returns to society with recovering mental tone in the shortest time as giving prompt and proper medical treatment to patient in emergency situation, and the Correctional Administration(CA) is purposed for the convict to return and settle down to society after release from prison in success as executing schooling, enlightenment activity, vocational training to convict who was quarantined from the society for the term of imprisonment. The EMS and CA will coincide each other which is reverting people to society in safety. This study aims to suggest the developmental program of EMS in correctional facilities through the cause of emergency situation, system, human resources, establishment, medical equipments, state of budget and the point issue for safety of victim who has many chances that is exposed to physical damage and disease because of particularity of lower culture in correctional facilities and the staff who works there. First, in the view of the correctional facility security system, a proper number of the emergency rescuers should be employed. Second, the effective transportation system along with some emergency medical equipment needs to be established. Third, the correctional officers and the prisoners should be learned the first-aid training which is realistic, practical and systematic. Fourth, the cooperative system should be established such as 1339 emergency medical information center in society. Fifth, the Ministry of Health and Welfare must increase EMS budget for correctional facilities.

  • This study analyzed paired middle school students' verbal and physical interactions in small group learning using augmented reality. Twelve 8th graders were paired to take classes of solubility and melting/boiling points based on augmented reality. These classes were videotaped and recorded. After the classes, all the students participated in a semi-structured interview. The results were analyzed in three sections; individual statement units of verbal interaction, interaction units of verbal interaction and physical interaction. In the individual statement units of verbal interaction, the proportion of information question/explanation was found to be high. In the interaction units of verbal interaction, the proportion of simple interaction was the highest, followed by elaborated interaction. Beneath the elaborate interaction, the proportion of cumulative interaction was found to be the highest, followed by reformative interaction. In the physical interaction, writing a worksheet and gazing at a virtual object were higher. On the basis of the results, effective ways to form a proper environment in small group learning using augmented reality are discussed.

  • 본 논문은 프로젝션 화면에서 사용자와 컴퓨터간의 상호작용을 위한 인터페이스인 리바이저를 제안한다. 리바이저는 프로젝션 화면에서 사용자의 손 제스처로 문서교정 부호를 인식하여 전자문서를 교정하는 인터페이스 시스템이다. 프로젝션 화면에서 이러한 제스처를 인식하려면 두 가지 문제가 있다. 하나는 다양한 빛의 변화와 복잡한 배경을 가지는 프로젝션 화면에서 전방물체를 검출하는 것이고, 다른 하나는 사용자의 연속적인 움직임에서 사용자의 의도를 알아내는 것이다. 전방물체를 검출하기 위해 프로젝터로 입력되는 영상과 카메라에 의해 캡쳐된 영상 사이의 색상정보를 사용한다. 이 색상정보는 다양한 빛의 변화와 복잡한 배경에서 전방물체를 구별할 수 있게 한다. 연속된 제스처를 인식하기 위해 적출과 인식이 포함된 새로운 제스처 적출방법을 제안한다. 실험결과 제안된 시스템에서 의미없는 움직임이 포함된 제스처 시퀀스에서 사용자 제스처의 인식률은 평균 93.22%로 만족할만한 결과를 보였다.

  • A proficiency test is one of programs which Korea Research Institute of Standards and Science(KRISS), as national metrology institute, is putting in operation for the mutual recognition arrangement. The Fluid Flow Group of KRISS evaluated the measurement capability for liquid flowmeter calibrator of the national calibration and test organizations. The uncertainty of national standard system was estimated in accordance with Guide to The Expression of Uncertainty in Measurement (ISO), and the turbine flowmeter, which was used for the round-robin test as a reference flowmeter, was characterized. The round-robin tests with the turbine flowmeter package were carried out in 1995 and 1999. The test results of the organizations and those of KRISS agreed within $\pm0.2$%. It is found thus that the organizations have the traceability of the national standard for liquid flow measurement.

  • To analyze the skeletal characteristics of the open bite, the faces of normal occlusion and open bite were measured using a cephalogram. The factors which were greatly different from normal occlusion were selected. The effects of these factors on the incisal overbite and correlation on these factors were studied. The following results were obtained: 1. The 13 factors which comprised the characteristics of the open bite were obtained. (Table 5) 2. The cause and amount of the open bite were dependent on the skeletal angulation than skeletal length. 3. For determining the incisal overbite, most highly correlated single factor was the interincisal angle. 4. The correlation on the selected 13 factors which comprised the characteristics of the open bite was obtained. (Table 6) 5. The open bite was due to combination of various factors than due to single factor. (Table 3,4).
