The purpose of this study was to identify observation methods, observation targets and their changes in elementary school students' observing aquariums. Silurus microdorsalis, Orthrias nudus, Iksookimia rotundicaudata and Semisulcospira bensoni in two aquariums were observed for 40 minutes in every week during 10 weeks by elementary children. Students' observation methods and targets were analyzed with their observation diary. Also the change of observation methods and targets on each species were analysed based on the observation diary. This study found the facts which was change of observation methods and observation targets according to observable theme of each species as time goes by. The results also found children's various methods and targets in observing living objects and observation methods were changed variously during 10 week-observation. The results of this study may provide more various and systematic norm and assessment criteria for teaching observation.

SAR (Synthetic Aperture Radar) is an imaging radar which can scan and image Earth System targets without solar illumination. Most Earth observation Shh systems operate in X-, C-, S-, L-, and P-band frequencies, where the shortest wavelength is approximately 1.5 cm. This means that most opaque objects in the SAR signal path become transparent and SAR systems can image the planetary surface targets without sunlight and through rain, snow and/or even volcanic ash clouds. Most conventional SAR systems in operation, including the Canada's RADARSAT-1, operate in one frequency and in one polarization. This has resulted in black and with images, with which we are familiar now. However, with the launching of ENVTSAT on March 1 2002, the ASAR system onboard the ENVISAT can image Earth's surface targets with selected polarimetric signals, HH+VV, HH+VH, and VV+HV. In 2004, Canadian Space Agency will launch RADARSAT-II, which is C-band, fully polarimetric HH+VV+VH+HV. Almost same time, the NASDA of Japan will launch ALOS (Advanced land Observation Satellite) which will carry L-band PALSAR system, which is again fully polarimetric. This means that we will have at least three fully polarimetric space-borne SAR system fur civilian operation in less than one year. Are we then ready for this new all weather Earth Observation technology\ulcorner Actual imaging process of a fully polarimetric SAR system is not easy to explain. But, most Earth system scientists, including geologists, are familiar with polarization microscopes and other polarization effects in nature. The spatial resolution of the new generation of SAR systems have also been steadily increased, almost to the limit of highest optical resolution. In this talk some new applications how they are used for Earth system observation purpose.

The purpose of this study was to analyze the processes of observation teaching and the types of observation in elementary life science class. For the purposes of this study, 40 teachers majoring in elementary science education participated in surveys on the processes of observation teaching. In addition, after videotaping the observation classes conducted by three teachers, each teaching in the 3rd to 5th grade, and their one hundred and eight students, we analyzed the processes of observation teaching. As a result, the processes of observation leaching in elementary science class were categorized into 12 stages (motivation, stating the objective, recognizing objects to observe, free and subjective observation, introducing ways to observe, observing by the simple way, introducing additional ways, observing by the manipulative way, making a note of observation, looking over the contents of observation, finding regularities, consolidation). In the types of observation, teachers and students performed mostly simple observing by the visual way. Teachers introduced time-independent/non-compared/whole observing; students concentrated on time-independent/non-compared/particular observing as targets. Thus, students carried out observing in the types of observation that teachers had presented. Consequently, the analysis about the processes of observation teaching can establish an effective teaching program for observing in scientific activities by reconstructing its observing target and suitable topic. The analysis about the types of observation can be applied to set up strategies for improving observation skills.

본 연구에서는 차량측량시스템에 사용할 수 있는 코드(Coded) 타겟을 설계, 제작하고 이를 자동으로 식별하고 타겟 중심의 영상좌표를 획득하는 방법을 개발하였다. 차량측량시스템은 CCD, GPS, INS 장비를 통합 탑재하여 도로상에 존재하는 시설물과 노면에 대한 3차원 정보를 획득할 수 있는 시스템이다. 차량측량시스템은 특성상 카메라 검교정과 외부표정을 위해서 미리 설치된 타겟을 사용하며 표정작업을 위한 영상좌표 획득은 수동에 의한 방법이 사용되어 왔다. 그러나 코드 타겟을 사용하며 타겟의 자기인식(Self-Identifying)을 통해 각 영상에서 관측된 타겟을 하나의 공액점으로 인식 가능하고 자동으로 타겟 중심의 영상점 획득이 가능하다. 이처럼 자동화된 타겟 관측 및 영상점 획득이 가능하다면 차량측량시스템의 카메라 검교정 및 외부표정을 작업의 효율성을 향상시키고 영상좌표 획득의 일관성을 유지하는데 매우 효과적일 것으로 판단된다.

The Intensive Monitoring Survey of Nearby Galaxies (IMSNG) is a high cadence observation program monitoring nearby galaxies at < 50 Mpc with high probabilities of hosting supernovae (SNe). The current number of main IMSNG targets is 60, but with new wide-field facilities joining IMSNG, there is a possibility of increasing the likelihood of catching the early light curves of SNe among galaxies in the vicinity of the main targets. To test the feasibility of the expansion of the sample galaxies, we examine how much the probability of catching SNe increases by adjusting the field of view of the RASA36 telescope which is one of the IMSNG facilities with a large field of view of 6.25 deg2. We calculate supernova rates (SNRs) of galaxies within the FoV that contains main IMSNG galaxies from the stellar mass and star formation rate of the galaxies. Based on the SNRs of these galaxies, we find the best pointing of the telescope towards the highest SNR region. As a result, we present improved total SNR, with respect to the ordinary pointing on average where the IMSNG main target is placed at the center of FoV. The actual observation should be followed to test the effect of this strategy.

Target-tracking algorithm based on ad hoc camera sensor networks (ACSNs) utilizes the distributed observation capability of nodes to achieve accurate target tracking. A compressed sensing-based multiple-target tracking algorithm (CSMTTA) for ACSNs is proposed in this work based on the study of camera node observation projection model and compressed sensing model. The proposed algorithm includes reconfiguration of observed signals and evaluation of target locations. It reconfigures observed signals by solving the convex optimization of L1-norm least and forecasts node group to evaluate a target location by the motion features of the target. Simulation results show that CSMTTA can recover the subtracted observation information accurately under the condition of sparse sampling to a high target-tracking accuracy and accomplish the distributed tracking task of multiple mobile targets.

본 논문은 연기 공부의 기본이자 재현연기에 관한 바이블이라고 하는 스타니슬랍스키 학파의 배우교육 프로그램 중 자기 자신과의 작업에서 역할과의 작업으로의 교량적 역할을 하면서 역할 창조의 출발점이라고 할 수 있는 관찰에 관한 연구이며, 상대적으로 이에 대한 연구가 부족한 한국 연극계의 현실에서 관찰의 필요성과 유용성, 종류와 단계별 접근 방법 등에 대해 기술하였다. 배우는 무엇보다도 본인이 구현해야 할 극 중 배역에 적합한 관찰대상을 포착해야 하며, 대상이 포착되었다면 먼저 자신의 '신체를 통한 따라하기'를 거쳐 체화하기를 진행하여야 한다. 이와 더불어 '신체행동의 원리'를 파악해 이를 맡은 역할의 상황에 따라 가감과 증폭 및 응용을 통한 적용의 과정을 거쳐야 한다. 또한 단순한 외형 복제의 차원을 극복하기 위하여 '감정이입을 통한 동일화'를 거쳐야 하며 '반복을 통한 몸으로 익히기 과정'을 통해 자기화를 이루어야 한다. 끝으로 부분적이고 단편적으로 끝날 수 있는 관찰의 과정이 희곡 전체를 다루는 전막 공연을 해내기 위해서는 각각의 단편적인 인물의 행동을 종합적으로 정리하면서 역할에 적합하게 설계한 행동총보를 구성하여 지속적이고 일관성 있는 집중력으로 역할을 창조해 나가야 할 것이다.

We report the preliminary results of our GMVA(Global mm VLBI Array) observation at the frequency of 86 GHz. Observation were made in the dual polarization mode (LCP and RCP), to produce the polarimetric maps with the maximum angular resolution which the array is capable of. We aim to link the source-integrated AGN polarization properties with the polarized spatial source structure, by mapping the polarized "fine structure" of the target AGN. We selected 2 targets, 0954+658 and 0716+714, which (1) have been observed multiple times by the PdBI polarimetric monitoring program; (2) have sufficient integrated fluxes ($S_{90GHz}$ > 1 Jy) ; (3) are close enough to resolve the source structure < 1 pc with given angular resolution ; and (4) are located at high northern declination for good UV coverages. As preliminary results, we present LL and RR polarized images of each target with the maximum angular resolution of ${\sim}60{\mu}as$. Extended structures, probably the jet outflows, are discovered in both sources.
