“…This study selects four judgment bases, practical experience, theoretical basis, peer understanding, and intuitive judgment and gives three-level quantitative values. At the same time, experts' familiarity is divided into five levels: “very familiar,” “relatively familiar,” “general,” “relatively unfamiliar,” and “unfamiliar,” and different quantitative values are given (see Table 2 for details) [ 18 ].…”

Understanding the interests and needs of online health education for college students, exploring the concepts, procedures, models, and approaches of health plans, learning about mental health online, and developing a comprehensive online mental health education plan for as many college students as possible are always very popular. Based on the development and support of online mental health education for students, from the perspectives of teachers and college students, this paper investigates online mental health education for college students in a city, combined with data interviews and Delphi routes; through electronic questionnaires, 900 college students and 30 students were selected by faculty members to conduct an investigation. With descriptive statistics, reliability and availability, chi-square tests, and other options, this paper examines data on student Internet usage and current status and we have the Psychiatry Network. The results show that 91.75% of college students study online every day and 61.72% spend more than 4 hours online every day. Satisfaction with the Internet has a certain impact on the online application and use of the health college education. Students’ online motivations and behaviors are multicultural. In order to build a mental health education network, educators believe that the primary goal should be to improve the mental health of college students.

“…Pesce et al created WQI min and achieved a reasonable assessment of water quality using fewer water quality indicators . Other researchers have also used WQI min combined with weights of parameters to select key parameters for different basins. , However, these weights of parameters are based on methods that include expert opinion bias, such as the Delphi method, despite researchers’ efforts to reduce it. − Machine learning (ML) can solve multidimensional, nonlinear problems based on big data, can avoid the subjective differences of traditional methods, and has the potential to become a method for identifying key water quality indicators and assessing surface water quality.…”

Multidimensional indicators of surface water are key to assessing the water quality. Cost and time could be saved if surface water can be accurately assessed by fewer indicators. Therefore, it is necessary to screen key water quality indicators for different basins. This study collected 35 water quality indicators (42 315 observations) along the Wujingang basin. Cluster analysis and correlation coefficients were used to identify homogeneous categories of water quality indicators. Frequent pattern mining (FPM) was used to remove redundant indicators. Finally, the water quality assessment after the removal of redundant indicators was validated by classification analysis. Results of the silhouette coefficient and within-cluster sum of squared errors indicated that K-means was the optimal clustering model. Concomitant indicators Pb, Cl − , NO 3− , TN, V, and Al were identified using FPM. Decision tree verified that the performance did not decrease after removing Pb, Cl − , V, NO 3 − −N, and Al. These indicators were redundant for the Wujingang basin and could be monitored less frequently when there is no special use. This study provides important information for developing a selection framework based on multidimensional water quality data, which could serve as a baseline system for the selection of key water quality indicators in a specific basin.
