To improve the practical effect of an information system security course for students majoring in information security, a teaching method based on the theory of inventive problem solving (TIPS) that combines case-based teaching and project practice was introduced in the class. Adopting innovative thinking methods, we instructed students on the projects and goals of curriculum design. Using TIPS tools, the students completed complex projects. To test the teaching results, we examined 121 students who received case-based teaching using the TIPS method to design innovative projects. Quantitative data were collected using a statistically analysed anonymised questionnaire, while qualitative data collected from student reflective reports were thematically analysed. Through the in-depth development involved in the teaching of this course, their thinking and problem-solving ability significantly improved. The teaching effect evaluations indicated that this teaching method effectively improved students' practical abilities. This method was found to be conducive to planning students' future careers.

Based on the method for identifying the boundary of movable water bodies (MWBB), the spatial distribution of reclamation projects in the Guangxi Beibu Gulf were identified over the past 40 years and the impact of these engineering facilities on hydrodynamics was also evaluated. The results showed that 163.8 km2 of natural sea areas in the Guangxi Beibu Gulf were occupied through reclamation in the last 40 years. The effects of land reclamation on tidal amplitude were more pronounced in the second period (2001–2018) than in the first period (1987–2001), particularly in the tidal channels of Qinzhou Bay and Fangcheng Bay, where the amplitude difference ranged from 8 to 15 cm, representing a 40–55% increase. The reduction in the sea area because of land reclamation has changed the hydrodynamics in the Guangxi Beibu Gulf, including reducing the tidal volume, altering the amplitude variations, and increasing the seaward residual currents, all of which could cause significant problems for the coastal environment.

In 3 consecutive years from 2016 to 2018, extreme ocean warming events, or marine heatwaves (MHWs), occurred during boreal summers in the East China Sea (ECS) and South Yellow Sea (SYS), which is unprecedented in the past four decades based on the satellite record. In this study, we used a high‐resolution hydrodynamic model based on Finite Volume Community Ocean Model (FVCOM) to simulate the evolution of these warming events. An upper ocean temperature budget (0–20 m) analysis based on the model results shows that the shortwave radiation and the ocean advection anomalies jointly contributed to the anomalous warming in the three successive summers (June–August) in the SYS and the north part of the ECS. In addition, the reduction of surface wind speeds during the 2016 and 2017 summers further weakened the vertical mixing, thereby enhancing the anomalous warming in the north part of the ECS adjacent to the SYS. During the three summers, the increases of shortwave radiation were closely related to the East Asian Summer Monsoon (EASM) variability, which reduced the cloud cover in the ECS and SYS, whereas the advection anomalies were mostly associated with regional wind anomalies. In summer 2018, upper ocean heat was transported into the central trough of the SYS, accumulated in an anticyclonic eddy generated by the anomalous wind stress curls. Therefore, despite the primary driver of the MHWs is the EASM variation, regional processes are critical to driving the spatial pattern of the MHW intensity in the ECS and SYS. Plain Language Summary: Marine heatwaves, known as periods of extreme warming at the sea surface, can last for days to months and cause damages to the marine environment and marine life. In the East China Sea and the South Yellow Sea, the frequent occurrences of harmful algae blooms are often associated with marine heatwaves. Satellite data reveal that marine heatwaves occurred in the East China Sea and the South Yellow Sea during the three boreal summers from 2016 to 2018, which is unprecedented in the past four decades. Using a numerical model of the ocean, we examined the marine heatwaves during these three successive summers. We show that the increased solar radiation, ocean current anomalies, and reduced vertical mixing were three critical factors for the warming events in the three summers. This study helps the fisheries and aquaculture industries in the East China Sea and the South Yellow Sea to better manage the environmental risks under a warming climate by predictions of marine heatwaves. Key Points: Marine heatwaves in the ECS and SYS during 2016–2018 summers were caused by shortwave radiation, current, and vertical mixing anomaliesShortwave radiation increases in summers were due to reductions of the cloud cover, closely related to the East Asian Summer Monsoon variabilityAn anticyclonic eddy in SYS in summer 2018, driven by regional wind anomalies, played a significant role in trapping anomalous heat [ABSTRACT FROM AUTHOR]

Wan, W.; Feng, X.; Liu, Q.; Yin, B.; Yang, D., and Gao, G., 2019. Study of the tide and tidal currents in the Bay of Bengal based on refined simulations. Journal of Coastal Research, 35(1), 33–40. Coconut Creek (Florida), ISSN 0749-0208. A high-resolution, two-dimensional, hydrodynamic tidal model of the Bay of Bengal was developed using the Advanced Circulation (ADCIRC) Model to study the tide and tidal currents in the Bay of Bengal. The simulations conformed to the observations, and because of the use of a high-resolution, triangular grid, characteristics of the tide and tidal currents were computed more accurately than in previous studies. The results indicated that tides in most of the Bay of Bengal are semidiurnal, whereas those in the seas SE of Sri Lanka are mixed and predominately semidiurnal. There are two degenerate amphidromic points, one at the NE end of the head of the bay and the other at SE Sri Lanka, whereas there is an amphidromic point at the seas SE of Sri Lanka. The form of the M2 tidal current is rotary on the continental shelf and rectilinear in coastal areas and seas distant from the continental shelf. Four major tidal currents are in a NW–SE direction, in the western part of the head of the bay, and in a NE–SW direction in river estuary areas. Results from the eastern part are the opposite. The amplitudes and major axes of four tides and tidal currents increase upon entering the head of the bay, whereas those of the M2 tide are the largest. [ABSTRACT FROM AUTHOR]
