This paper reports on the outline and the status of the TAMA-300 project, the 300 meter laser interferometer gravitational wave detector developed by a team of scientists of several research institutes and universities in Japan. In fact the project has been funded and its construction started at the National Astronomical Observatory, Mitaka, in spring 1995. And the constructions of the tunnels for the east-west and north-south arms and of the central building are completed and a half of pipes for laser beams were brought in. Very stable laser oscillator has been almost completed and mew techniques such as vibration isolations, recycling of laser power, and suspension of mirrors by double pendulums have been developed. In fact the purposes of the project are to establish techniques necessary for future km-class detectors and to operate the detector to catch possible gravitational wave events in nearby galaxies such as Andromeda, the target sensitivity being $3 {\times} 10^{-21}$ at 300Hz.

The K-GMT group launches a new science program designed to promote the observational research capabilities of Korean Astronomical Society. The science program (SP, hereafter) will provide the access to the observational facilities that is required for the completion of science proposals selected based on their scientific merits. The SP will invite the submission of proposals from all members of Korean Astronomical Society annually starting from mid-2013. We will introduce the rationale, action plan, and major timelines for the new K-GMT SP to the Korean astronomical community members.

This work addresses the development of the astronomical observatory all through history, from an architectural point of view, as a building in relation to the observing instruments and their functioning as a heterogeneous work center. We focused on 32 observatories (in the period 1259-2007) and carefully analyzed the architectures. Considering the impact of the construction itself or its facilities on the results of the research (thermal or structural stability, poor weather protection, turbulence, etc.), there is little attention paid to theories or studies of the architectural or construction aspects of the observatories. Therefore, this work aims to present a theoretical-critical contribution that, at least, invites the reflection of those involved in the development of astronomical observatories in the future.

The pandemic of COVID-19 has made it difficult to gather participants in offline astronomical programs since March, 2020. For this reason Gwacheon National Science Museum has developed online programs of the partial solar eclipse and the Asteroid Day event in June, the celebration for launching Mars 2020 in July and Perseids in August. In this poster, we present how to plan each of them and research on methods that deliver astronomical contents to viewers effectively. In addition, we introduce preparing a couple of online programs in the rest of this year.

From 2009, CEOU of Seoul National University has been utilizing the United Kingdom Infrared Telescope (UKIRT) at Mauna Kea, Hawaii, as one of its research facilities. UKIRT is a telescope with 3.8m primary mirror, and it is currently the largest telescope specialized for infrared observations. We will summarize our research activities using UKIRT, which include Infrared Medium-deep Survey (IMS) of proto-clusters and high redshift quasars, NIR imaging programs of Gamma Ray Bursts (GRBs), Gamma Ray sources, and SNUQSO quasars. Our research programs include international collaboration with the UK GRB team, the NASA/Swift team, Pomona College, and National Central University of Taiwan. We will also touch on our future plan of using UKIRT.
