Ltd., Korea 3 Professor, School of Civil and Environmental Engineering, Kookmin University, Korea 4 Researcher, R&D Center, Innose Tech Co. Ltd., Korea INTRODUCTION South Korea experienced its biggest earthquake in recent history on September 12, 2016. The Gyeongju earthquake of magnitude (Mw) 5.4 has initiated a significant activity in the area of seismic safety for nuclear power plants. Initial reports indicate that the nature of this earthquake is similar to the recent findings from geophysical investigations in Central and Eastern United States (CEUS), i.e., the earthquake ground motions contain not only the low frequency content but also some high frequency content. As is the case with most of the nuclear plants in CEUS, the safe shutdown earthquake (SSE) for most of the Korean plants have only low frequency content (below 10 Hz). Therefore, the nuclear plants in Korea are beginning to conduct a detailed seismic safety assessment of their structures, systems, and components (SSC). In the context of seismic safety assessment, high frequency motions are not likely to cause damage to structural systems as the displacements associated with such motions are relatively very small. Yet, past experience around the world has shown that electrical instruments such as relays, breakers, and contact switches can exhibit loss of functionality due to high frequency motions. -

Received: 2 May 2017; Accepted: 19 June 2017; Published: 24 June 2017 Abstract: The purpose of this study was to develop a Korean climate change vulnerability assessment tool, the Vulnerability Assessment Tool to build Climate Change Adaptation Plan (VESTAP). Based on Intergovernmental Panel on Climate Change methodology, VESTAP can be used to evaluate Korea’s vulnerability to major climate impacts (including 32 conditions in 8 categories). VESTAP is based on RCP 4.5/8.5 scenarios and can provide evaluation results in 10-year intervals from the 2010s to 2040s. In addition, this paper presents the results of a case study using VESTAP for targeted assessment of health vulnerability to heat waves under the RCP 8.5 scenario for the 2040s. Through vulnerability assessment at the province level in South Korea, Daegu Metropolitan City was identified as the most vulnerable region. The municipality and submunicipality levels of Daegu were also assessed in separate stages. The results indicated that Pyeongni 3-Dong in Seo-Gu was most vulnerable. -
Investigation of Changes in Indoor Radon Concentrations Before and After Seismic Activities in Gyeongju and Pohang, Korea

On September 12, 2016, earthquakes with a magnitude of 5.1 and 5.8 consecutively occurred in Gyeongju. 14 months later, an earthquake with a magnitude of 5.5 occurred in Pohang, about 30 km away from Gyeongju, on November 15, 2017. This study investigated the change in the indoor radon concentrations before and after earthquakes to identify if there is any pattern between them and found an interesting pattern. Prior to earthquakes, radon anomalies, which are radon concentration deviating by more than ±2σ from the seasonal average, was usually identified. When 5.0 or greater magnitude earthquakes occurred, the indoor radon concentrations decreased sharply a few days before them, and then continuously increased until the occurrence of the earthquake.

Running Title: A Living Treatment Support Center for COVID19 Title: A Suggestion from South Korea for Treatment of Mild or Asymptomatic COVID-19 Infected Patients: Living and Treatment Support Center Authors: Sun Young Lee1, EunKyo Kang1, Hyemin Jung, Min Sun Kim, Belong Cho, and Yon Su Kim Author affiliation: Seoul National University Hospital, Seoul, Republic of Korea (S.Y. Lee, E. Kang, H. Jung, M.S. Kim, B. Cho, Y.S. Kim) Abstract With the outbreak of coronavirus disease 2019 (COVID-19), there is a need for efficient management of patients with mild or no symptoms, which account for the majority. The aim of this study is to introduce the structure and operation protocol of a living and treatment support centre (LTSC) operated by Seoul National University Hospital in South Korea. The existing accommodation facility was converted into a 'patient centre' where patients was isolated. A few Medical staff here performed medical tests and responded to emergencies. Another part of the LTSC was 'remote monitoring centre'. In this center, patients’ self-measured vital signs and symptoms were monitored twice a day, and the medical staff staying here provided video- consultation via a smartphone.
