The video game market has become increasingly popular among children and adolescents in recent decades. In this research, we investigated the Video Game Addiction Scale (VGAS) for Chinese children and adolescents. We aimed to examine children and adolescents’ prioritization on the VGAS criteria and comparative analysis of the trend of video game addiction among them. A cross-sectional paper questionnaire study was conducted on 1400 Chinese students from grade 3 (9 years old) to grade 12 (18 years old). The respondents had to complete the socio-demographic information and the VGAS test. The VGAS characteristic was prepared in 18 criteria, which was the combination of the Video Game Addiction Test (VAT), Gaming Addiction Scale (GAS), and Revised Chinese Internet Addiction (CIAS-R). Eventually, the VGAS criteria prioritization was ranked methodologically through the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method for each grade separately. Additionally, the Analytic Hierarchy Process (AHP) weighting technique was utilized to analyze the video game addiction of each grade under the four alternatives, individually. The results indicate that 3rd-grade students with some levels of addiction were the youngest who felt their life would not be fun without video games. Students in 5th grade with some levels of addiction were the youngest students who disclosed that their willingness to play video games is for forgetting their problems or feeling down. Moreover, they played video games more than before, thus, they did not sleep enough. Pupils of grade 6 reported that they played video games more than last semester. In their opinion, it is fair to play video games this much and does not need to reduce playing hours. Not getting enough sleep because of playing video games was seen in 7th graders as their first preference. 10th-grade students were the first to neglect to do their important responsibilities for playing video games. None of the 7th and 12th graders were somehow safe from video game addiction. In conclusion, playing video games can negatively affect studying, sleeplessness, getting far from society, and skipping important responsibilities for school students. Furthermore, the symptoms of video game addiction had seen at younger ages. These data provided insights for decision-makers to target effective measures to prevent children and adolescents’ video game addiction.

In the process of rehabilitation, the objectivity and the accuracy of rehabilitation assessment have an obvious impact on the follow-up training. To improve this problem, using a multi-sensor source, this paper attempts to establish a comprehensive assessment method of the finger rehabilitation effect, including three indicators of finger muscle strength, muscle fatigue degree, and range of motion. Firstly, on the basis of the fingertip pressure sensor of the End-Effector Finger Rehabilitation Robot, a mathematical model of finger muscle strength estimation was established, and the estimated muscle strength was scored using the entropy weight method. Secondly, using an sEMG signal sensor, a fatigue monitoring system was designed in the training process, and the fatigue degree was determined on the basis of the change trend of the eigenvalues of MAV and RMS. Lastly, a human–machine motion coupling model was established, and the joint range of motion acquisition and scoring model were obtained on the basis of the motor encoder. According to the above three indicators, using the AHP assessment method to establish a comprehensive rehabilitation assessment method, the effectiveness of the method was verified by experiments. This paper provides a potential new idea and method for objective, accurate, and convenient assessment of finger function rehabilitation, which is of positive significance for alleviating the burden on rehabilitation doctors and improving rehabilitation efficiency.

Waste management is one of the most important problems concerning contemporary civilization. The increase of the number of population and consumerism, cause producing different kinds of waste. Along with the economic progress and the technical progress, humanity became the largest producer of waste in nature. Segregation is still the biggest problem of selective collection of waste. The awareness and the knowledge of people in caring about the natural environment is growing. Unfortunately, many of them are not convinced to sort municipal waste. However, in making a decision about segregation, each of them could be influenced by other factors. The aim of this study was to collect detailed criteria which influence the decision about waste segregation among people not segregating the municipal waste. Then the main criteria were grouped and their influence on the global decision was shown. In this paper a method of the Analytical Hierarchization of the Process was used. Research was conducted among 50 randomly chosen respondents from Poland. The results of the research showed that the financial penalties and the possibility of reducing the payment for sorted municipal waste could increase the amount of people who segregate the municipal waste. Increasing the awareness of reducing the natural resources consuming is not as important criterion as two mentioned before.

The population and the consumerism increase cause producing different kinds of waste. Segregation is still the biggest problem of the selective collection of waste. The awareness and the knowledge of people in caring about the natural environment is growing. More people are becoming convinced to sort their waste. However, in making a decision about segregation, each of them could be influenced by other factors. The aim of this study was to collect detailed factors which influence the decision about waste segregation. Research was conducted among people who regularly sort waste. Then the main factors were grouped and their influence on the global decision was shown. In this paper a method of the Analytical Hierarchization of the Process was used. Research was conducted amongst 30 randomly chosen respondents from the Wielkopolska Voivodeship. The results of the research showed high awareness of people about the need to care about the natural environment.

A significant number of enterprise owners and managers realize an importance of innovations for the future existence of their business and its development. It appears that in theory and business practice a number of innovation concepts can be found, however for managers and business owners it is difficult to be knowledgeable in innovation concepts in order to use them in practice. Innovation concepts represent solutions outline, which react to the business ability to innovate. Each innovation concept is different in the area of focusing on innovation problem and way of detailization. Chosen innovation concepts can be applied when solving following problems: Identifying the innovation potential, organizational readiness for innovation and achieved levels of innovation climate, or the actual implementation of the innovation process and the evaluation of innovation. It is worth noting that concrete innovation concepts are not at the same level of usability in practice, some of them need to be better specified for application in business. A set of innovation concepts was created and evaluated the usability of individual concepts in the enterprise. The evaluation was carried out by qualitative analysis using selected criteria, which were determined by an expert group with the assistance of the researcher. Variants of usability of innovation concepts were defined subsequently. At the same time, decision-making model based on the Analytic Hierarchical Process was designed and applied in order to classify innovation concepts. Decision-making model can be used by managers for the purpose of innovations management while choosing the concept of innovation. Web of Science 21 4 158 141
