Impact of wind pattern and complex topography on snow microphysics during ICE-POP 2018 Kwonil Kim1, Wonbae Bang1, Eun-Chul Chang2, Francisco J.

Snowfall in north-eastern part of South Korea is the result of complex snowfall mechanisms due to a highly- contrasting terrain combined with nearby warm waters and three synoptic pressure patterns. All these factors together create unique combinations, whose disentangling can provide new insights into the microphysics of snow in the planet. This study focuses on the impact of wind flow and topography on the microphysics drawing of twenty snowfall events during the ICE-POP 5 2018 (International Collaborative Experiment for Pyeongchang 2018 Olympic and Paralympic winter games) field campaign in the Gangwon region. The vertical structure of precipitation and size distribution characteristics are investigated with collo- cated MRR (Micro Rain Radar) and PARSIVEL (PARticle SIze VELocity) disdrometers installed across the mountain range. The results indicate that wind shear and embedded turbulence were the cause of the riming process dominating the mountain- ous region. As the strength of these processes weaken from the mountainous region to the coastal region, riming became less 10 significant and gave way to aggregation. -

M. Chung ([email protected]) 3147 Abstract In August 2002, Typhoon RUSA hit Korea with severe gale and storm, causing exten- sive damage throughout the whole country and especially in the Gangneung area. Even on a single day, Typhoon RUSA recorded up to 879.5 mm of rainfall in the 5 Gangneung area. Quantitative and qualitative analyses of the scale of Typhoon RUSA are performed in this study. Most of the inland affected by RUSA in the Korean Penin- sula recorded heavy rainfall, equivalent to a return period of more than 200 years. Es- pecially, rainfall of 24 h duration exceeded the maxima observed so far. -
Food Storytelling and Its Development in Gangwon Province, Korea1-Focused on Kim Yu-Jeong's Novels
International Journal of Bio-Science and Bio-Technology Vol.6, No. 6 (2014), pp.21-28 http://dx.doi.org/10.14257/ijbsbt.2014.6.6.03 Food Storytelling and Its Development in Gangwon Province, Korea1-focused on Kim Yu-jeong's Novels- Yun-won Lee and Jae Yeong Lee Hankuk University of Foreign Studies, Dongdaemungu, Imunro 107, Seoul, Korea [email protected], [email protected] Abstract Gangwon Province, located in the mid-eastern part of the Korean Peninsula, is blessed with beautiful mountains and beaches that offer some of the best sceneries and vacation spots throughout the year. It also provides a wide variety of food that embraces local identity. The mountainous region in the west and the seaside region of the east both add more colors to its local food in terms of recipes and ingredients. In addition, this study focuses on its renowned novelist Kim Yu-jeong, developing food contents through storytelling which was reflected on his works. Keywords: Gangwon Province, Chuncheon-si, Kim Yu-jeong, storytelling, local food 1. Introduction The consumers in the present times intend to get style, story, experience and even sensibility embedded in the products when they purchase goods. Considering this, storytelling is likely to play a role to expand the space in which the consumers experience by influencing their way of thinking, leading the consumers' change in terms of related activities and aspects. That is, story is to connect the consumers to products; storytelling is essential to stimulate consumers' sensibility. Such storytelling method in marketing is actively utilized in the recent years, adopted in the promotion of local brands or even a certain region. -
Alpensia Sliding Centre
Invitation PyeongChang, Republic of Korea · 2nd International Training Period (ITP) : 21 October–29 October 2017 The Overview of PyeongChang General Information of Korea, Gangwon & PyeongChang Korea (officially the "Republic of Korea") is a historical state in Northeast Asia located on the Korean Peninsula, which is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the East Sea. The southern and western parts of the peninsula have well-developed plains, while the eastern and northern parts are mountainous. The population of the Koreans is about 50 million. Korea is chiefly populated by a highly homogeneous ethnic group, the Koreans, who speak the Korean language. Gangwon-do is a mountainous province, (a much greater part is occupied by mountains) and is usually divided into two areas, Yeongdong and Yeongseo, with the Taebaek Mountains, which form the backbone of the Korean Peninsula, in the middle. PyeongChang is a county located in mid-southern region of Gangwon Province, Korea. Being located inland on a plateau, PyeongChang presents a continental climate with big temperature swings between day and night, with overall lower temperature compared to other regions of same altitude. Having a relatively large area among Counties, it presents complicated weather patterns, and different weather conditions even within the same region. The high-altitude region in northeast part of the county presents a very distinctive weather pattern. It is relatively cool in the summer, with average temperature of 19.1 ℃, but comes under heavy snowfall during the winter, due to Northeastern airstream risen by the Taebaek Mountains. -

The Analysis on Forest Fire Occurrence Characteristics by Regional Area in Korea from 1990 to 2014 Year

This study analyzed the characteristics of forest fires occurred in 16 administrative districts for recent 25 years (1990∼2014) to examine regional characteristics in forest fire occurrence. Forest fire occurrence reflects regional characteristics depending on climatic factors as well as region’s society-cultural factors. Results showed that the first cause of forest fire occurrence was carelessness by human activities throughout all administrative districts, however, the second cause depends on regional characteristics. As the results of forest fire occurrence period analyzed for 10 days, the most forest fires occurred in the southern region during January to March, while forest fires in the northern region occurred mostly during March to April. We classified forest fire occurrence patterns into three types (centralized: Gyeonggi-do, dispersal: Busan, horizontally distributed: Gyeongsangnam-do) by multi-temporal analysis for forest fire occurrence period. Key Words: regional characteristics in forest fire occurrence, forest fire frequency, forest fire occurrence cause, forest fire occurrence pattern Introduction emerge as a global disaster. -
Predicting Inflow Rate of the Soyang River Dam Using Deep Learning
water Article Predicting Inflow Rate of the Soyang River Dam Using Deep Learning Techniques Sangwon Lee 1 and Jaekwang Kim 2,* 1 Department of Applied Data Science, Sungkyunkwan University, Suwon 16419, Korea; [email protected] 2 School of Convergence, Sungkyunkwan University, Seoul 03063, Korea * Correspondence: [email protected] Abstract: The Soyang Dam, the largest multipurpose dam in Korea, faces water resource management challenges due to global warming. Global warming increases the duration and frequency of days with high temperatures and extreme precipitation events. Therefore, it is crucial to accurately predict the inflow rate for water resource management because it helps plan for flood, drought, and power generation in the Seoul metropolitan area. However, the lack of hydrological data for the Soyang River Dam causes a physical-based model to predict the inflow rate inaccurately. This study uses nearly 15 years of meteorological, dam, and weather warning data to overcome the lack of hydrological data and predict the inflow rate over two days. In addition, a sequence-to-sequence (Seq2Seq) mechanism combined with a bidirectional long short-term memory (LSTM) is developed to predict the inflow rate. The proposed model exhibits state-of-the-art prediction accuracy with root mean square error (RMSE) of 44.17 m3/s and 58.59 m3/s, mean absolute error (MAE) of 14.94 m3/s and 17.11 m3/s, and Nash–Sutcliffe efficiency (NSE) of 0.96 and 0.94, for forecasting first and second day, respectively. Keywords: dam inflow; machine learning; bidirectional LSTM; Seq2Seq; deep learning Citation: Lee, S.; Kim, J. Predicting Inflow Rate of the Soyang River Dam Using Deep Learning Techniques.
