All RIGHTS RESERVED Corporate Profile GS Energy was incorporated on January 3, 2012 as a result of GS Holdings’ spinoff of GS Caltex, its refining, marketing, chemicals and transportation arm, creating a new independent Korean energy company. Subsequently, GS Energy assumed the high growth businesses previously operated by GS Caltex including, exploration & production and renewable energy operations. Further, by acquiring GS Caltex’s electric & gas utilities operations, GS Energy has solidified its position as an integrated energy-specialized holding company. Value chain integration and operational agility are fundamental to GS Energy’s long term growth strategy. GS Energy is organized into four interrelated segments: Exploration & Production, Refining & Petrochemicals, Gas & Power and Green Growth. Our integrated business model allows us to capture synergies among our different segments and activities. Our upstream businesses include the development of oil & gas projects across the globe, from the Middle East to the Americas and Southeast Asia. Further downstream, GS Energy is currently constructing a Liquefied Natural Gas (LNG) terminal in South Chungcheong Province to optimize value chain integration and to ultimately provide a steady flow of electric power and gas to customers through various subsidiaries and affiliates. Furthermore, given our focus on sustainable growth, we have been actively developing our technical know-how in the alternative energy sector.

CMCC-CM, INM-CM4, and IPSL-CM5A-MR RCP 4.5 and 8.5 scenarios were selected as the future dry conditions using Runs theory and Standardized Precipitation Index (SPI). For historical (1980–1999), present (2000–2019), and future periods (2030s, 2050s, 2070s, and 2090s) of the 6 scenarios, SWAT model was used to simulate the future dam water supply stability. The stability was evaluated in terms of reliability (RT), resilience (RS), and vulnerability (V) based on the monthly target storage. The results showed that the future RT can be decreased to 0.803 in 2050s IPSL-CM5A-MR RCP 8.5 scenario from present 0.955. The future RS and V showed the minimum value of 0.003 and the biggest value of 3567.6 106 m3 in 2070s IPSL-CM5A-MR RCP 4.5 scenario.

The country’s 9th Basic Plan for Electricity Power Supply and Demand (9th BPESD) presents a unit-level operation schedule for coal power plants that would see nearly 27 GW of coal-fired power capacity still online in 2034, with coal eventually being phased out in 2054, almost 25 years later than is required to be Paris Agreement compatible.

Of 38 mines, we found 19 with measured concentrations of NOA. We evaluated the average of airborne NOA concentrations according to the environmental exposure category. When evaluated regionally by dividing into two clusters, the mean concentrations in activity-based sampling (ABS) scenarios exceeded the Korean exposure limit (0.01 f/cc) in both clusters. Moreover, airborne NOA concentrations in agricultural activity (5.49 × 10−2 f/cc) and daily activity (6.95 × 10−2 f/cc) had Citation: Lee, S.; Kang, D.; Kim, Y.; the highest values for clusters A and B, respectively. The excess lifetime cancer risk of one region Kim, Y.-J.; Kim, S.-Y.
