As Internet technology develops, SNS users are increasing. As SNS becomes popular, SNS-type crimes using the influence and anonymity of social networks are increasing day by day. In this paper, we propose a fake account classification method that applies machine learning and deep learning to statistical and image data for fake accounts classification. SNS account data used for training was collected by itself, and the collected data is based on statistical data and image data. In the case of statistical data, machine learning and multi-layer perceptron were employed to train. Furthermore in the case of image data, a convolutional neural network (CNN) was utilized. Accordingly, it was confirmed that the overall performance of account classification was significantly meaningful.

This study was conducted with the purpose of understanding the factors that influence smartphone addiction on adolescents' school adaptation. The subjects were examined with a focus on students currently attending middle schools in Gwangju Metropolitan City, and data analysis was conducted using SPSS 26.0 to examine the factors influencing school adaptation, focusing on the inducements and forced inducements that lead teenagers to fall into smartphone addiction. As a result of the analysis, it was found that anonymity and desire satisfaction among the attractive factors leading to smartphone addiction have a negative impact on school adaptation, and the forcing factors that cause adolescents to become overly dependent on smartphones include online games, online chatting, online addiction, and social interaction. It was analyzed that both action and information search had a negative impact on adolescents' school adaptation.

This study investigates relationship between Internet users' information privacy protection behavior and environmental factors. Especially, this study focuses on users' behaviors regarding information privacy protection technology adoption. According to our research results, users' online privacy protective behaviors positively affected by governmental regulations expressed as an information privacy protection law.

As social networking services (SNS) become widely used tools for maintaining social relationships, people use SNS to express themselves online. Users are free to form multiple characters in SNS because of online anonymity. This phenomenon causes SNS users to easily demonstrate multiple personas that are different from their identities in the real world. Therefore, this study focuses on online multi-personas that establish multiple fake identities in the SNS environment. The main objective of this study is to investigate factors that affect online multi-personas. Fake online identities can have various negative consequences such as cyber bullying, cyber vandalism, or antisocial behavior. Since the boundary between the online and offline worlds is fading fast, these negative aspects of online behavior may influence offline behaviors as well. This study focuses on teenagers who often create multi-personas online. According to previous studies, personal identities are usually established during a person's youth. Based on data on 664 teenage users, this study identifies four emotional factors, namely, closeness with others, relative deprivation, peer pressure and social norms. According to data analysis results, three factors (except closeness with others) have positive correlations with users' multi-personas. This study contributes to the literature by identifying the factors that cause young people to form online multi-personas, an issue that has not been fully discussed in previous studies. From a practical perspective, this study provides a basis for a safe online environment by explaining the reasons for creating fake SNS identities.

The purpose of this study was to construct a grounded theory as the basis for developing future nursing interventions by describing and analyzing the holistic lives of the physically handicapped adolescents. The subjects were 10 physically handicapped adolescents who were attending a rehabilitation school located in Kyunggi region and could understand and respond to the questions. The aim and purpose of the study were explained to the subjects, and only those who accepted to participate in the study were selected as the actual study subjects. The study data were collected from July to November 2000. The investigators provided detailed explanations to the subjects about keeping the anonymity of the subjects name and confidentiality of the information provided by the study subjects. The subjects received in-depth interviews by the investigators. Each interview took about 40 minutes to 1 hour and 30 minutes, and each subject received interviews with the range of one to 3 times. All interviews were recorded under the permission of the subjects. The investigators formed field notes after finishing each interview. In the process of data analysis, 'realizing the difficulty due to physical handicap' was found to be the causal condition, whereas' acceptance of physical handicap' was identified as the context. Then, we identified' awaring as the valuable being' as the core phenomenon, 'support from family and social group and spiritual help' as the intervening condition, 'effort for adaptation' as the strategy, and' finding the meaning of life' as the consequence. Through the theoretical model derived from this study, an important aspect the lives of physically handicapped adolescences was identified that' awaring as the valuable being' help them cope better and find the meaning of life in spite of suffering they experience.

There occur various crimes in cyber space hiding behind anonymity to avoid punishment by criminal law. One of the most serious crimes committed in cyber space is defamation against others under the cloak of freedom of expression. The infringements by defamations in cyber space are made all of a certain and widespread that the victims have no time to react, and for that reason, the shocks by the defamation are much serious and severe compared with that committed in off line. However, press and publication shouldn't infringe on other's honors, right, public order or social ethics in liberal democrat society which values much the human dignities and values as stipulated in Article 21 section 4 of the Constitution. Protection of personal honor is also the basic rights guaranteed by the Constitution as much as the freedom of expression, and by extension, such harmful behaviour shouldn't be included in the freedom of expression area. In this way, slander can be considered as the minimum limitation of the freedom of expression.

This paper presents result of researching personal information exposure of Korean twitter and facebook users. Personally identifiable information such as e-mail and phone numer is exposed in the accounts less than 1%. However there are many cases that a person is identified by non personally identifiable information. For example, 350 thousands accounts are distinguished with other accounts because its name is unique. Using combination of information such as name and high school, we can distinguish 2.97 millions accounts. We also found 170 thousands account pairs that are candidate of one users' own account. Linkability between two accounts in two different domains means that the person is identified. Currently, only personally identifiable information is protected by policy. This paper shows that the policy has limited effects under the circumstances that a person can be identified by non personally identifiable information and the account linking is possible.

Cyberspace is on its way to experience dynamic change, hereby encompassing technical and social diversities and multiplicities. The internet, with a history of no more than 10 years, has drastically changed the way, meaning and conduct of our lives, the structure and function of society and communication. Even in psychology, in which the purpose is to scientifically look into the human mind and explore its behavior, the in-depth inquiry into the human behavior and psychological features of the cyberspace have become an increasingly important issue. Research suggests that psychological features and concepts brought about during the process of communication in cyberspace have been influenced by the digital mode following the analogue one, and by the online mode following the off line one. It also suggests that, with new issues peculiar to information society, cultural structures should be re-conceptualized, reconstructed and reevaluated in various fields. This approach to the changing role, meaning and style within society should be rearranged and referred to as cyber psychology.
