Due to the important role played by emotion in human interaction, affective computing is dedicated in trying to understand and regulate emotion through human-aware artificial intelligence. By understanding, emotion mental diseases such as depression, autism, attention deficit hyperactivity disorder, and game addiction will be better managed as they are all associated with emotion. Various studies for emotion recognition have been conducted to solve these problems. In applying machine learning for the emotion recognition, the efforts to reduce the complexity of the algorithm and improve the accuracy are required. In this paper, we investigate emotion Electroencephalogram (EEG) feature reduction and classification using Stack AutoEncoder (SAE) and Long-Short-Term-Memory/Recurrent Neural Networks (LSTM/RNN) classification respectively. The proposed method reduced the complexity of the model and significantly enhance the performance of the classifiers.

As military service members are fully permitted to use mobile phones for sickness after work, it is time to minimize the direct collection of personal information from telecommunication companies when opening mobile phones to secure the safety of military service personnel's personal information. Prior to introducing the use of mobile phones by soldiers after work, the Ministry of National Defense established a security control system such as blocking the mobile phone shooting function to prevent security accidents and concerns about some adverse functions such as illegal cyber gambling, game addiction, and viewing pornography. come. Mobile telecommunications companies entrust personal information processing tasks, such as opening mobile phones, to telecommunications agencies and carry out management and supervision, such as checking the status of personal information protection measures. When a military service member opens a mobile phone, a personal information management agency is newly established using the right to portability of personal information, and a system for requesting the transmission of personal information from the military service member is proposed.

The purpose of this study was to investigate the actual status of Internet gaming disorder in university students, the relationship between perceived stress, social support, lifestyle and Internet gaming disorder, and the medium effect of social support in the relationship between perceived stress and Internet gaming disorder. The main results of the survey and analysis of 1,154 university students located in Gyeonggi Province are as follows. First, the prevalence of Internet gaming disorder among university students was 14.0 percent, which is very high. Second, the perceived stress had a positive correlation with the Internet gaming disorder. The more negatively perceived stress events occurred by university students, the higher the degree of internet gaming disorder was. Third, social support had a negative correlation with perceived stress and internet gaming disorder. The higher the support of parents, friends, and others, the lower the perceived stress and the lower the internet gaming disorder. Fourth, social support partially mediated the relationship between perceived stress and Internet gaming disorder. Even though stress was negatively perceived, the degree of internet gaming disorder was low when social support was high. Fifth, among the lifestyle habits of students, the rate of alcoholism was higher in the Internet gaming disorder group than in the non-disorder group. Finally, the results of the study and ways to prevent Internet gaming disorder among university students were discussed.

This research is involved in looking into the cognition pattern of social worker position of a fourth-year student majoring in Social Welfare. The purpose of this research is to offer a basic data needed for education of the students who are preparing to get a job of a social worker. For this, applying Q methodology, this research made an objective analysis of their subjective response to social worker position targeting the 30 students in the department of social welfare at the four-year-course college located in Gyeongsangbuk-do and Gyeongsangnam-do. The research results showed that the cognition pattern of the college students' occupational view on social welfare position could be categorized into the three; The first pattern is a "job-skeptic & reality-evasive" type, who tends to perceive the position of a social worker as the one having a lot of job exhaustion and much workload, showing a pessimistic view on the meaning or a sense of mission of a social worker position. The second pattern is a "practice-centered & specialized-job-seeking type" who tends to think much of practical aspects of a social worker job and to seek after the position of a social worker as a specialized job, and at the same time to rely on the policy or system for a social worker position. The third pattern is a "value-oriented & self-achievement type", who tends to think much of the necessity of value or ethics in putting social welfare into practice and also to make much of self-achievement through the channel of a social welfare worker position. Taken together, it might be possibile to turn out professional human resources, but this research thinks it is more necessary to place the education of values of a social welfare worker.

Purpose: This study was done to develop the multidimensional scale of addictive behavior for adolescents. Methods: The process involved construction of a conceptual framework, initial items, verification of content validity, selection of secondary items, and extraction of final items. The participants were 636 adolescents in six middle schools and four high schools. Results: Seventy items were selected for the final scale, and categorized 8 factors explaining 56.5% of total variance. The factors were labeled as game addictive behavior, shopping addictive behavior, mobile phone addictive behavior, nicotine addictive behavior, television addictive behavior, gambling addictive behavior, alcohol addictive behavior, and internet addictive behavior. The scores for the scale were significantly correlated with addictive personality and self-control. Cronbach's alpha coefficient for the 70 items was .94. Scale scores identified adolescents as addictive behavior group, risk group, and average group. Conclusion: The above findings indicate that the multidimensional scale of addictive behavior for adolescents has good validity and reliability when used with adolescents. More importantly, it provides the first step toward developing a addiction prevention program.

The purpose of this study was to investigate the influences of the smartphone overuse on health and academic impairment in adolescents. This study used data from Korea youth risk behavior web-based survey of 2017. This survey was conducted on 64,991 adolescents(middle and high school students), and 62,276 (95.8%) responded. The researchers used frequency analysis, independent t test, chi-square test and Pearson correlation analysis using SPSS 22. As a result, the usage rate of adolescents's smartphone was 54,603 out of 62,276, which was 87.7%. The purpose of smartphone usage was messenger(1st rank, 27.3%), SNS(2nd rank, 18.7%) and game(3rd rank, 13.3%). The average daily use time of the smartphone was 206.68±194.73 minutes. Girl students showed significantly more use time of smartphones than boy students(p<.001). Students with more than 206 minutes of smartphone use had worse health and academic performance than students with less than 206 minutes(p<.001). Time of smart phone usage and academic ability showed a weak correlation(p<.001, r=.245). The present findings showed that the higher the smartphone usage, the lower the health level and academic ability, and the author discussed these results.
