Background: Mobile phone addiction has become a serious problem among college students. Studies have examined the relationship between self-control and mobile phone addiction; however, few have discussed the indirect mechanism. This study aimed to examine the mediating role of fear of missing out in the relationship between self-control and mobile...

Family health education is a must for every family, so that children can be taught how to protect their own health. However, in this era of artificial intelligence, many technical operations based on artificial intelligence are born, so the purpose of this study is to apply artificial intelligence technology to family health education. This paper p...

The development of intelligent urban computing has carried out different critical smart ecological and energy harvesting topics such as intelligent cities and societies. The main concept of the sustainable smart city is established for collecting and negotiation of the Internet of things (IoT) devices and smart applications to help and enhancement...

Human emotion recognition is a key technique in human–computer interaction. Traditional emotion recognition algorithms rely on external actions such as facial expression, which may fail to capture real human emotion since facial expression signals may be camouflaged. EEG signal is closely close to human emotion, which can directly reflect human emo...

The problem of mobile phone dependence is becoming more and more serious. Therefore, it is very important to explore the causes of mobile phone dependence and its psychological mechanism. One of the important characteristics of mobile phone dependence is the loss of control, which shows that self-control is an important factor affecting mobile phon...

In order to explore the situation of college students’ emotional state, regulatory emotion self-efficacy and mobile phone addiction tendency as well as their relationships, a total of 350 college students were assessed with Mobile Phone Addiction Tendency Scale (MPATS), Positive Affect and Negative Affect Scale (PANAS) and the Scale of Regulatory E...

In order to further study the current situation and relationship of college students’ mobile phone dependence, social support and sense of security, a questionnaire survey was performed on 409 college students using the college students' mobile phone addiction tendency scale, social support assessment scale and sense of safety scale. The results sh...

With the rapid development of science and technology, electronic payment platforms have become increasingly mature, and network consumption has become increasingly popular. As a special consumer group, more and more college students tend to become addicted to online shopping. This study examines the probability and difference of 183 college student...

The effect of pretreatment on sulfuric acid leaching Ni and Co from superalloys was studied. The influence of pretreatment, milling time and leaching time on leaching rate of nickel and cobalt were mainly investigated. The results showed that after pretreatment of superalloys with the particle size of 180~380 μm, the leaching rate of Ni and Co coul...

The kinetics behavior of nickel and cobalt leaching from waste superalloys with sulfuric acid was investigated. The kinetics experiments were carried out with the ratio of liquid to solid of 400:1, the acid concentration of from 10% to 25%(volume fraction) and the temperature of from 55 to 75℃. The results showed that the apparent activation energy...

For wasted organic catalysts containing rhodium, rhodium was enriched by reduction-grinding and separation. Additives promote iron grain growth and metallic iron enrich rhodium during the reduction process, and then iron ore concentrate containing rhodium is enriched by magnetic separation. The study obtains the optimum process parameters, i.e. the...

From two aspects of both the domestic and abroad respectively comprehensive review the status of the comprehensive recovery of the waste superalloys in different fields, this paper introduces and comments the regeneration technology of the waste superalloy such as: carbothermal reduction-arc smelting method, electrochemical deposition, molten salt...

In order to promote transparency and coherence for language learning, teaching and especially estimating, Council of Europe (COE) developed The Common European Framework of Reference (CEFR) and European Language Portfolio (ELP). The CEFR and the ELP are both the most influential documents of the last decade in the fields of language learning and te...
