Jihun has completed his PhD in 2013 and postdoctoral studies from College of Optical Science and Engineering in University of Arizona. Currently he is the senior researcher in Korea Astronomy and Space Science Institute (KASI) and working on Solar Coronagraph which will be built on International Space Station (ISS). He has been involved to various telescope projects including ground-based and space telescope. His expertise is in optical designing, testing, and performance evaluation. He also has been performed simulations of Adaptive Optics (AO) of ground-based telescope.
Korea Astronomy and Space Science Institute (KASI) has been developing the Solar Coronagraph system which will be installed on the International Space Station (ISS) in 2021(Figure1). We have adapted and studied the compact coronagraph system proposed by NASA. We have developed a prototype of the compact coronagraph in which we can observe the solar coronagraph without the occulters. It was used for the Total Solar Eclipse (TSE) observation in 2016. Even we could not obtain the satisfactory result in the observation due to poor environment, we could obtain lessens and learns. We have a plan to develop another prototype of coronagraph system to test filter wheel, polarizer, and CCD, and it will be used for the Total Solar Eclipse in 2017. After the TSE observation, we have a plan to develop the coronagraph system used in the balloon air-borne to demonstrate for the space model. In this poster we introduce the progress and current status of the project and focus on optical design works for Total Solar Eclipse (TSE) observation.
Sadroddin Alavipanah is a doctoral researcher, research assistant and GIS lecturer since 2014 at Geographical institute, Humboldt University of Berlin, Germany. Sadroddin completed his masters in ‘Global Change’ studies at University of Bayreuth, Germany, in 2013. His research interest lies in the area of urban remote sensing and cities mitigation strategies to the changing climate. In recent years he advanced his researching skills on integrating three dimensional remote sensing data to improve the understanding on urban ecology. He believes that three-dimensional studies could advance the concept of sustainability in cities.
Recent urban ecosystem service research projects have focused on the spatial configuration of urban environment and its Impact on local and global scales. These result of these studies were mainly two dimensional. However, studies focusing on producing three dimensional results (3D) –such as volume, shadowing effect, height- were absent. In a systematic review we have selected 298 articles were selected for in-depth critical analyses. Selected publications show that satellite technologies have become popular and have provided useful data for monitoring and mapping cross-scale ecological research at various spatial, temporal, and spectral scales. Analyzing selected publications also show that there is a shift in the sub-theme of reviewed publications toward climate change adaptation and mitigation by using remote sensing data in a regional scale. Understanding and considering 3D data into research will improve our understanding in environmental interactions in urban area. Further studies should progress in the development of both 3D data and results. Implementing 3D data and results helps to better understand the coupling of humans and their environs. It will be then a critically important step toward developing ecologically friendly cities.
