The effects-based operation, which would reduce unnecessary efforts and meaningless sacrifices incurred during a war and simultaneously reach the will of the enemy leadership by strategic attacks, was discarded for the reason that it was difficult to apply it to military power except for airpower. However, cyberspace, which can be thoroughly logical and calculated, can be suitable for conducting effects-based operations. This study examined a way to carry out effects-based operations in such cyberspaces. It laid the foundation for overcoming the limitations of effects-based operations revealed in previous battle cases and executing the operations in cyber battlespace where the boundary between physical and cyberspaces gradually disappeared. Futhermore, it demonstrated that effects-based operations could be carried out in cyberspace by establishing a military strategy, which could conduct the operations through an analysis of previous cyber-attack cases.

This study was conducted with male/female teenagers to examine the interaction between their attachment to social media and their self-identity in both real space and cyberspace. Among the subjects, male teenagers tended to use social media more than female teenagers. Also, the more friends/followers they have, the more they would use the service itself. In the subordinate correlation of the subjects' self-identity in both cyberspace and real space, most areas showed positive correlation. And each subregion of the areas of real-space ego-identity and social media addiction showed positive correlation with them as well. On the other hand, in areas of social media addiction and cyberspace ego-identity, all areas showed negative correlation except the area of dominance. Through this experiment, it was proven apparent that there needs to be proper management of teenagers that are overusing and are addicted to social media, and that programs should be developed to mediate the subjects in regards to each subregion of real space and cyberspace ego-identity.

This study investigates the effects of children's social relationships and psychological characteristics on their behavior problems. Behavior problems comprise violations of norms, bullying, and deviant behavior in the cyberspace. A data set of 2949 Korean children in their 4th grade is analyzed to yield three main results. First, variables such as contact with delinquent friends, aggressiveness, stress of appearance complex, gender, and depression have significant effects on violations of norms. Children who have more delinquent friends, higher level of aggressiveness, stress of appearance complex, or depression report more violations of norms. Second, delinquent friends, stress of peer relationship, aggressiveness, stress of appearance complex, gender, parents' violent attitudes toward children, and negative self-image are turned out to be important variables predicting bullying. Children with more delinquent friends, higher level of stress, higher level of aggressiveness, or lower self-image are more likely to experience bullying. Children who perceive their parents to be violent show more bullying experience. Third, each of aggressiveness, delinquent friends, stress of appearance complex, gender, relationship with teacher, and family income has significant effect on deviant behavior in cyberspace. Children with higher level of aggressiveness, more delinquent friends, stress of appearance complex, or negative impression of teacher are more likely to deviate in cyberspace. Children from higher income families report more deviant behavior in cyberspace. Boys show more experiences in every category of behavior problems than girls.

Evaluating battle damage after conducting an attack on selected targets during warfare is essential. However, regarding the assessment of battle damage caused by cyber-attacks, some methods available under limited circumstances have been suggested so far. Accordingly, this paper suggests a militarily applicable, comprehensive, and specific method of battle damage assessment from battle damage assessment methods in combat assessment theories from the understanding of cyberspace. By using cyberspace components, this paper classifies cyber targets, suggests the assessment methods of data damage, social cognitive damage, derived damage, and the existing battle damage assessment methods such as physical damage, functional damage, and target systems, and provides an example to demonstrate that this method is applicable to the actual past cyberattack cases.

Digital Evidence Data in cyberspace is easy to modify or delete, and changes are reflected in real time, so it is necessary to acquire evidence data quickly. Collecting evidence on the client side is advantageous in that data can be acquired without time delay due to additional administrative procedures, but collection of large data is likewise vulnerable to collection time delay problem. Therefore, this paper proposes an automated evidence collection method on the client side, focusing on the major web-based services in cyberspace, and enables efficient evidence collection for large volumes of data. Furthermore, we propose a digital evidence collection system in cyberspace that guarantees the integrity of the collected digital evidence until the court submission.

This study focused on violent act, such as verbal offensive and other acts of violence such as cyber bullying, personal information infringement. Online bullying is seriously taking place online, as juvenile violence is seriously debated due to recent school violence. In particular, it is necessary to seek countermeasures by considering the nature of cyber violence in cyberspace, particularly when stalking victims in cyberspace have died from stalking. The study examines the problem of defamation and defamation of character and tries to identify problems. Measures were taken to enact cyber defamation laws. To this end, the Commission analyzed cases of defamation and defamation of character and considered legal precedents. The study intends to study cyber defamation and defamation of character. First, I want to differentiate between cyber libel and defamation of character. Second, I intend to raise the need for cyber defamation of cybercrime and consider the offence of contempt for the criminal justice system. Third, seek ways to protect against cyber defamation and defamation of character.

Ensuring national security in cyberspace is becoming an increasingly important issue, given the growing number of cybercrimes due to adaptation to new security and protection technologies. The purpose of this article is to study the features of counteracting, preventing, and detecting crimes in the virtual space of Ukraine on the example of cases and analysis of the State Center for Cyber Defense and Countering Cyber Threats CERT-UA and the Cyber Police Department of the National Police of Ukraine. The research methodology is based on the method of analysis and study of cases of crime detection in the virtual environment of the State Center for Cyber Defense and Countering Cyber Threats CERT-UA and the Cyber Police Department of the National Police of Ukraine. The results show that the consistent development of the legal framework in 2016-2020 and the development of a cyber-defense strategy for 2021-2025 had a positive impact on the institution-building and detection of cybercrime in Ukraine. Establishing cooperation with developed countries (USA) has helped to combat cybercrime by facilitating investigations by US law enforcement agencies. This means that international experience is effective for developing countries as a way to quickly understand the threats and risks of cybercrime. In Ukraine, the main number of incidents concerns the distribution of malicious software in the public sector. In the private sector, cyber police are largely confronted with the misappropriation of citizens' income through Internet technology. The practical value of this study is to systematize the experience of overcoming cybercrime on the example of cases of crime detection in a virtual environment.

The purpose of this research is to examine the self-concept in the cyberspace, self-efficacy, relationship with friends, subjective well-being and academic grade among adolescents who are addicted to Internet and those who are not addicted to Internet. A total of 1,057 adolescents (male=545, female=512), 326 from middle school, 361 from high school, and 370 from special education school, participated in the study. The results are as follows. First, qualitative analysis of the conception of self in the cyberspace indicates that those adolescents addicted to Internet reported that in the cyberspace they have fun, followed by they are the same as in real life, they spend time in cyberspace and they can become an imaginary person. Those adolescents not addicted to Internet reported that in the cyberspace they are the same as in real life, followed by they spend time in cyberspace and they can become an imaginary person. When they play Internet games, majority of adolescents in both groups reported that it is fun, followed by they become engrossed and they become aggressive. Second, those adolescents who are not addicted to Internet had higher scores on self-efficacy than those adolescents who are addicted to Internet, including self-regulatory efficacy for learning, relational efficacy, and resiliency of efficacy. Third, the number of friends and close friends that adolescents who are not addicted to Internet were not significantly different from those adolescents who are addicted to Internet. However, those adolescents who are not addicted to Internet were more likely receive social support from friends and were less likely to be social excluded than those adolescents who are addicted to Internet. Fourth, those adolescents who are not addicted to Internet had significantly higher scores on subjective well-being than those adolescents who are addicted to Internet. Fifth, those adolescents who are not addicted to Internet had significantly higher scores on both subjective and objective academic grade than those adolescents who are addicted to Internet.

Cyberspace is becoming increasingly important. Incidentally, there exist possibilities of the industrial secrets leaked, cyber attacks, privacy protection problems. In addition, there are growing concern of cyber war between nations. Thus potential hazards in cyberspace and the extent of damage are getting bigger. Therefore, a systematic understanding of cyber damage and damage scale is very important and damage estimation method should be developed to establish solid cyber protection system. In this study, current and potential damage types are understood and damage scales are surveyed based on the analysis of existing studies and try to develop a reasonable methods to estimate economic effects of cyber protection.

New technologie of information and interaction create ambiguous, multifaceted relationships between concepts and realities that once seemed clear and simple. The acvent of cyberspace implies the existence of cyberplaces and relationships among cyberspace and places that could be as or more complex then those that exist among the spaces and places of the non-digital world. Virtual reality-the current uses of infomation technologies to create replicas of places and processes in the world-offers a point of exploring such relationships. But more penetrating insights become evident in the examination of real virtuality-the uses of information technologies to enhance the experience of places in the world. Real virtuality offers geographers a variety of innovative and powerful tools for augmenting the effectiveness and domain of their craft. Widespread use of real virtuality by geograpgers will alter their use of data, methods, and theory in research, teaching, and practice.
