Current State of In-Cabinet Response Spectra for Seismic Qualification of Equipment in Nuclear Power Plants
Transactions, SMiRT-24 BEXCO, Busan, Korea - August 20-25, 2017 Division V CURRENT STATE OF IN-CABINET RESPONSE SPECTRA FOR SEISMIC QUALIFICATION OF EQUIPMENT IN NUCLEAR POWER PLANTS Abhinav Gupta1, Sung-Gook Cho2, Kee-Jeung Hong3, Minsoo Han4 1 Professor, Dept. of Civil, Construction and Environmental Engineering, NC State University, USA 2 Director, R&D Center, Innose Tech Co. 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. -

Optimal Rescue Ship Locations Using Image Processing and Clustering
S S symmetry Article Optimal Rescue Ship Locations Using Image Processing and Clustering Cho-Young Jung 1 and Sang-Lok Yoo 2,* 1 Department of Marine Science and Production, Kunsan National University, Gunsan 54150, Jeonbuk, Korea; [email protected] 2 Mokpo Maritime University, Mokpo 58628, Jeonnam, Korea * Correspondence: [email protected]; Tel.: +82-61-240-7175 Received: 15 October 2018; Accepted: 11 December 2018; Published: 2 January 2019 Abstract: Currently, globalization of the world economy has also resulted in a shipping volume increase. However, this growth in maritime traffic has led to increased risk of marine accidents. These accidents have a higher probability of occurring in regions where geographical features such as islands are present. Further, the positioning of rescue ships in a particular ocean region with a high level of maritime activity is critical for rescue operations. This paper proposes a method for determining an optimal set of locations for stationing rescue ships in an ocean region with numerous accident sites, such as in the Wando islands of South Korea. The computational challenge in this problem is identified as the positioning of numerous islands of varying sizes located in the region. Thus, the proposed method combines a clustering-based optimization method and an image processing approach that incorporates flood filling to calculate the shortest pixel value between two points in the ocean that detours around the islands. Experimental results indicate that the proposed method reduces the distance between rescue ships and each accident site by 5.0 km compared to the original rescue ship locations. Thus, rescue time is reduced. -

Dokdo is a volcanic island created by a volcanic eruption that promoted the formation of Ulleungdo (located in the East sea), which is ~87.525 km away from Dokdo. Dokdo is an important island because of geopolitics; however, because of certain investigation barriers such as weather and time constraints, the awareness of its insect fauna is less compared to that of Ulleungdo. Dokdo’s insect fauna was obtained as 10 orders, 74 families, and 165 species until 2017; subsequently, from 2018 to 2019, 23 unrecorded species were discovered via an insect survey. -

New Challenges Facing Asian Agriculture Under Globalisation
New Challenges Facing --------1-------- Asian Agriculture under Globalisation Volume II Edited by Jamalludin Sulaiman Fatimah Mohamed Arshad Mad Nasir Shamsudin 34 Farm Household Debt Problems in Jeonnom Province, Korea: ACose Study J.K. Park, P.S. Park and K.H. Song Introduction Farm loans have increased quite rapidly in the recent decades and the farm household debt 1 matter has become a serious socio-economic issue in Korea. In an effort to get around this critical issue, the government would prepare and implement impromptu new debt measures. Yet, the farm-debt ratio over farm income has been increasing very rapidly since the beginning of the WTO in 1995 and the IMF financial crisis of 1997, leading to 88 per cent as that of 2000, mainly due to low agricultural income. During the period of 1994 (the year right before the beginning of the WTO)-2000, farm household income had increased by 13.6 per cent but debt had increased by as much as 156.3 per cent (MAF, 2001 ). That is, farm household debt has been increasing very rapidly since 1995. Yet, the ratio of non-farm income accounted for around 32 per cent of farm income in recent years, which made it more difficult for farmers to repay their loans. This problem is getting even more complicated because of joint surety among the farmers, which would lead to total bankruptcy of farms including financially sound farms. Recently, more than 7 5 per cent of farm loans were utilised for the purpose of agricultural production. In order to cope with labour shortage problems due to the rural-urban migration of labour force, farmers began to purchase more agricultural machinery, which eventually led to the galloping farm household debts. -
60 Chapter V Conclusion and Recommendation for The
60 CHAPTER V CONCLUSION AND RECOMMENDATION FOR THE FUTURE OF JKFTA AND BOTH NATIONS The research question raised at the beginning challenges us to start contemplating in a different way than the usual. JKFTA has brought its own attention for its surprise appearance. But then scholars, business enthusiasts, and everyone else is presented by a delayed agreement. We have two important yet sensitive problems at our hand alongside with a postponed economic agreement, which initially, does not strike to be relevant to each other. But at the end of this research, there is a concrete happening between the two variables. The economic agreement has indeed postponed by the remaining historical disputes. At the very start, the birth of the notorious territorial dispute that is Liancourt Rocks is examined. The Liancourt Rocks is more than just mere islets. The islets are centuries old with many versions of the history of how it is found and many controversial debates for its ownership and value. Starting from ocean floor research, environmental research in general, military value, and then ended with the case of dignity. Past colonialism has indeed brought more and more bad impression to the people, making Liancourt Rocks as disputed today as it is in former times. Continuing with the matter of comfort women, nothing has been easier in the journey of this problem. It is also peaked at World War II, with many testimonies appearing in the Korean peninsula particularly Republic of Korea (ROK). It successfully garnered attention and pity. Victims began to be more ambitious in sharing their stories and demanding an apology from Japan’s government. -

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.
