Domestic violence in our society is where the abuser and the abuser live in the same space. Problems are left unresolved in families where abuse is reproducing. Domestic violence can be viewed as a crime that violates and tramples human rights. They rely solely on family support networks for solutions to domestic violence. The physical, emotional, and psychological pain and wounds that victims of domestic violence must endure are too deep. In order to help victims of domestic violence, case management services that can provide long-term and attentive help in the neighborhood or community are needed. For this, prevention and treatment of domestic violence should be considered together. And the interest and professional role of the community must follow.

With the spread of smart phones, the Internet became a major 'space' of students' daily life and, at the same time, negative aspects of the internet are affecting their life. However, it doesn't seem that there is enough research on this subject. This study was conducted on 278 students in Gyeonggi. The results were as follows. First, gifted students' information and communication ethics index was higher than general students. Second, there was no statistically significant difference according to the gender of information and communication ethics index. Urban districts showed lower index in the upper grades than the lower grades. Third, about 10% of the students had experience of contact with harmful content, and about 1% of students had experienced cyber-wrongdoing. Through the results of this study, systematic education of IT ethics at the elementary school grade level can be expected to prevent school violence, improve information and communication culture, and serve as a future work ethic.

Convergeance in the military operations can be attained by simultaneously integrating effects based on sensor, C2, shooter asset in multi-domain and there is no exception to special operations. However, because of challenges from enemy, terrain, geopraphy, and weather, it's not easy to intertwine effects created from ground, sea, air, cyber and electromagnetic spectrum, and space in special operations conducted in deep area. This study presented how to intertwine high-tech such as long-rane reconnaissance·strike drone, cutting-edge sensor, jamming pod, and modular repeater in order to offset aforementioned challenges. Several new high-tech are able to strengthen convergeance of special operations in accordance with the development of the 4th industrial revolution. Therefore, follow-up studies need to be continued making an efforts to search for them.

The purpose of this study is to explore keywords within stalking-related news articles according to political orientation through the text network analysis, and then to examine the implicit intentions. Selecting total 1,607 articles including 824 articles of the conservative press(The Chosun Ilbo, The Joongang Ilbo) and 783 articles of the progressive press(The Hankyoreh, The Kyunghyang Shinmun) reported from January 1, 2018 to December 31, 2022, this study explored the aspect of topic category drawn through the topic modeling technique based on LDA(Latent Dirichlet Allocation). In the results of this study, the common topics of the conservative and progressive press were improvement of the perception of gender-based violence, personal protection & intensity of punishment, and disclosure of stalkers' personal information. Regarding the topics differently shown in those two press, the conservative press showed stalkers' harmful act, and outline of 'murder case at Sindang Station' while the progressive press showed request for aggravated punishment on the 'murder case at Sindang Station', and eradication of sexual exploitation crime (in cyber space). The results of this study imply that there are changes in the type of reporting according to ideological opinions about stalking in news articles.

This research identified the normal structures of separated families, "wild-geese families"(husbands living in Korea apart from their wives and children who are studying abroad) as we called, in Korea. In particular, this study conducted in-depth interview, using qualitative research method, with 7 wild-geese fathers (fathers who are in order to understand their experiences of separated families. The research findings classified the wild-geese father's experiences into three phases which as "decision-making," "initial," and "maintenance." These phases can be described by five higher factors. First of all, in the phase of decision-making "internal or external needs of children studying abroad at early age" was found to be a crucial factor. Liberation and deficiency as results of separation" mainly described the initial phase. In the phase of maintenance, families experience "exhausted solitary lives," "filling up the families' empty space," and "double jeopardy-worry about both reunifying the family or separating the family, as the longer they are separated."

The study presents milestones for the Korean military to win the future battlefield based on the 4th Industrial Revolution. Chapter 1 deals with the necessity of research on how advanced countries operate industrial technology in the defense sector based on the 4th Industrial Revolution. Chapter 2 examines the current technology status of the 4th Industrial Revolution in Korea and the concept of Korean combat. Chapter 3 analyzes the military robotic technology of advanced military countries through examples of unmanned combat robots in the United States, Israel, and Germany. In the end, in future battles, it will be possible to dominate the battlefield only by taking a leap into a super-connected and super-intelligent military based on a high-tech platform. Our military should also research and develop military robotics in accordance with the characteristics of each combat system, and further expand and develop the concept of combat performance to protect our core capabilities and centers from enemy cyber, electronic warfare, and space attacks.

A space, real or virtual, comprises regions as its parts and physical objects residing in them. A coherent and sophisticated representaion scheme for their spatial relations premises the precision and plausibility in its associated agents' inferencing on the spatial relations and the development of events occurring in such a space. The existing spatial models are not suitable for a comprehensive representation of the general spatial relations in that they have limited expressive powers based on the dichotomy between the large and small scales, or support only a small set of topological relations. The representaion model we propose has the following distinctive chracteristics: firstly, our model provides a comprehensive representation scheme to accommodate large and small scale spaces in an integrated fashion; secondly, our model greatly elaborated the spatial relations among the small-scale objects based on their contact relations and the compositional relations among their respective components objects beyond the basic topological relations like disjoint and touch; thirdly, our model further diversifies the types of supported relations by adding the container property besides the soildness together with considering the gravity direction. The resulting integrated spatial knowledge representation scheme considering the gravity allows the diverse spatial relations in the real world to be simulated in a precise manner in relation to the associated spatial events and provides an expression measure for the agents in such a cyber-world to capture the spatial knowledge to be used for recognizing the situations in the spatial aspects.

Ambient Media (or ambient displays, Wisneski et al 1998) is one of newly emergent dynamic design objects, representing information through subtle changes of everyday objects and environments. Unlike the existing GUI-based media focusing on the situation that a user is concentrating the media, ambient media enable a user to be peripherally aware of the information without his/her concentration. In order to design ambient media, it is necessary to interpret the basic elements of dynamic changes in physical space and the proper method to apply them for peripherally representing information in ambient media. The aim of this study is to investigate dynamic design elements and the method to apply them for ambient media design in physical space. We explored and refined the type of the dynamic design elements, analyzing dynamic qualities of ambient media cases as well as various time based design fields. As a result, 4 dynamic elements - tempo, connectivity, intensity and rhythm- were proposed. By literature reviews related to peripheral awareness in psychology or ambient media, we analyzed the characteristics of dynamic design elements. Based on that, we developed a new ambient media, 'Cyber Pung-Kyung', and applied dynamic elements for designing the prototype system. The research outcome is expected to contribute designing ambient media which can represent information peripherally or centrally as needed. Understanding the dynamic design elements is helpful for designing various time based design outcomes as well.

As the manufacturing environment becomes more complex, traditional simulation models alone are having a lot of difficulties in reflecting real-time manufacturing situations. Although the Digital Twin concept is actively discussed as an alternative to overcome theses issues, many studies are being carried out only in the product design phase. This research presents a Digital Twin-based manufacturing environment framework for applying the Digital Twin concept to the manufacturing process. Twin model that is operated in virtual space, physical system and databases describing the actual manufacturing environment, are proposed as detailed components that make up the framework. To check the applicability of proposed framework, a simple Digital Twin-based manufacturing system was simulated in a conveyor system using Arena software and Excel VBA. Experiment results have shown that the twin model is transmitted real time data from the physical system via DB and were operating in the same time unit. The Excel VBA fitted parameters defined by cycle time based on historical data that real-time and training data are being accumulated together. This study proposes operating method of digital twin model through the simple experiment examples. The results lead to the applicability of Digital twin model.

Due to the changes in market place, new business types(e.g. e-business) have been rapidly emerged and increased. However, those new business types have not much been emerged n shipping and port related industries, and adoption rate of e-business in this area is very low, compared to other industries. Thus, to promote e-business in this area. many policies have been studied. However, most of previous studies have not been based on industrial structure, and results of these studies have mostly been case by case. Further, there have been no research based on the related theories. As a result, despite many of research and project for shipping and port related e-business, prominent achievements in this area have never to be presented. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed, and then, various policies based on results of those basic studies should be discussed. The aim of this study is to classify business types existed (or expected) in a port related industry, ship bunkering. This taxonomy was based on theories related to business layer(BL) and value chain(VC), and these BL and VC combination enabled to acquire all possible business types.
