        나노과학, 나노공학, 및 나노기술의 축적된 지식을 대중참여라는 관점을 첨가하여 대학원생이나 젊은 과학자들에게 가르치기 위하여, 오사카 대학은 2004년부터 다양한 교육 및 훈련 프로그램을 제공하고 있는데, 교학문적(交學問的) 대학원 부전공 과목, 야간 강좌, 단기 국제훈련 프로그램 등이다. 연속강의는 위성통신을 이용하여 교실에 전달되기도 한다. 또한 학생들은 현대시설을 활용한 실습을 통하여 직접, 나노소재와 나노소자를 설계, 제작, 측정, 특성분석 및 기능화 할 수 있다. 그리고 특별히 사회적, 법적, 윤리적 관계를 포함하는 나노소통에 관한 연구훈련 프로그램과 강좌 시리즈가 네 개 개설되어 있으니, "나노기술 경력 건설 강좌", "나노기술의 대중 참여", "나노기술 지도 설계", "목적과제 학습 및 훈련 프로그램(PAL)"이다. 전체 프로그램의 윤곽이 나노소통 특별 프로그램과 함께 소개되어 있다. In order to teach the accumulated knowledge of nanoscience, nanoengineering and nanotechnology to graduate school students and young scientists with the sense of public engagement, Osaka University started from 2004 to prepare and offer various kinds of education and training programs such as trans-disciplinary graduate-school minor program, evening course refresher program, short-term international research training program, etc. It offers a series of lectures, partly broadcasted live to satellite classrooms. In addition, the students can join intensive hands-on training programs using modern facilities, allowing them to design, fabricate, measure, characterize and functionalize nanomaterials and nanodevices. In addition, there are four specially designed lectures and research training programs aimed for nanocommunication including social, legal and ethical relationship: "Nanotechnology Career-up Lectures", "Social Engagement on Nanotechnology", "Road Map Design on Nanotechnology", and "Project-Aimed Learning and Training Programs (PAL)". The outline of the whole programs is described together with the specialized programs for nanocommunication.

        Differential Effects of Hip Rotation Range on Knee Abduction Biomechanics during Double-Legged Landing between Males and Females

        Tadashi Yasuda,Keiichi Oyanagi,Miyu Nakagaki,Hiromitsu Itoh 대한운동학회 2020 아시아 운동학 학술지 Vol.22 No.4

        [OBJECTIVES] Dynamic knee valgus is composed of hip-knee coupling. While females differ from males in passive hip motion, hip rotation range may alter muscle mechanics and neuromuscular activity. This study aimed to compare knee abduction biomechanics during double-legged drop-landing between males and females with different hip rotation ranges. [METHODS] This study included five females with the range of hip internal rotation (IR) > the range of hip external rotation (ER), five females with ER>IR, four males with IR>ER, and five males with ER>IR. There was no difference in other hip motions among them or no difference in hip muscle strength between the same sex groups. Three-dimensional motion analyses of the hip and knee joints were performed during double-legged drop-landing. [RESULTS] Multiple regression analysis of females with IR>ER showed that peak knee abduction moment (KAM) was associated with maximal hip abduction moment before detecting peak KAM whereas peak knee abduction angle (KAA) correlated with no variable. In females with ER>IR, peak KAM was associated with maximal hip ER moment before detecting peak KAM, hip ER muscle strength and hip adduction range while peak KAA correlated with peak hip abduction moment before detecting peak KAM. In males with IR>ER, peak KAM was associated with hip ER range and hip adductor strength whereas peak KAA correlated with maximal hip ER moment and maximal hip IR angle during landing. In males with ER>IR, peak KAM was associated with hip extensor strength, hip abduction range and hip flexion range whereas peak KAA correlated with hip ER moment before detecting peak KAM, hip ER muscle strength, and hip adduction range. [CONCLUSIONS] Hip rotation range may differentially affect hip-knee coupling strategy for knee abduction control during double-legged drop-landing between males and females.

        Oscillatory Structures Originating from the Faraday Rotation of a New Nonlinear Photoluminescence Band of Cd0.8Mn0.2Te

        Kouichi Katayama,Kensuke Miyajima,Masaaki Ashida,Tadashi Itoh 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.5

        By the selective excitation of localized excitons in Cd0:8Mn0:2Te at 2 K, a new nonlinear PL band (hereinafter referred to as the X band) appears on the higher energy side of the ordinary magnetic polaron band. When the X band is observed through a linear analyzer with weak magnetic fields (0 - 0.3 T), under a Faraday configuration, it exhibits an oscillatory structure. The energy interval of this oscillation is half that of the Faraday rotation spectrum observed in the transmission spectrum. Therefore, the oscillation is interpreted as being caused by the Faraday rotation of the X-band luminescence, which is first emitted near the surface of excitation, passes through the sample, is re ected back from the rear surface and then passes through the sample again.
