Pukyong National University

A student at PKNU won the 1st award at the marine and fisheries future research paper contest 2023

- Park Seong-Sik, ph.d. student received both 1st and 2nd award for two papers

Pukyong National University (President Jang Young-Soo) announced that Park Seong-Sik, a ph.d. student in the department of marine engineering, won both the grand prize and excellence prize at the marine and fisheries future research paper contest.

In this paper contest hosted by the Korea maritime institute and organized by each academic society in the marine and fisheries field, Park Seong-Sik received the grand prize from the Korean society of marine environment & safety and the excellence award from the Korean society for marine environment and energy.

He received the top award from the Korean society of marine environment & safety for his paper 'study on methods for selecting appropriate discharge sites to minimize the impact of heat polluted water on the marine environment' (advisor Kim Kyung-Hoi).

His paper was recognized as the best by the evaluation panel by developing a technique for selecting a suitable discharge site that can minimize the spread area of thermally polluted water by using numerical flow models and machine learning techniques to alleviate damage to fisheries caused by thermally polluted water from LNG bases or power plants.

He suggested that the most important variables that determine the diffusion area are the discharge amount of heat polluted water, the water temperature of the surface and bottom layers at the discharge point when not discharged, the salinity log of the bottom layer, the water temperature difference between the surface layer and the bottom layer water, and the density difference. He applied these variables to a Gaussian process regression (GPR) model to predict the diffusion area of heat polluted water, showing very high accuracy.

In addition, he received an excellence award from the Korean society for marine environment and energy for his paper 'research on the relationship between El Ni？o, La Ni？a and the occurrence of red tide along the coast of Korea' (advisor Kim Kyung-Hoi).

In this paper, he investigated the status of red tide occurrence along the coast of Korea (1981-2022) including identifying precipitation and river total nitrogen (TN) as major influencing factors and was highly evaluated for his research achievements. <Pukyong Today>
