The purpose of this study is to define determinants of VoIP user acceptance and to verify significant causality among latent variables - performance expectancy, effort expectancy, cost expectancy, social influence, facilitating conditions, behavioral intend, use behavior - based on UTAUT model. We presented the expanded hypotheses including the new factor, cost expectancy and analyzed the moderating effect of user age, gender and usage experience variables. For a accuracy of predicted results, we focused on survey analysis with 641 real user samples. Compared to previous studies, it is meaningful that this research verified the conceptual difference between behavioral intention and usage behavior. As a result, all proposed hypotheses accepted and moderating effects are supported significantly in age and use experience moderating variables.

Electronic payment system using Internet banking is a very important application for users of e-commerce environment. With rapidly growing use of fintech applications, the risk and damage caused by malicious hacking or identity theft are getting significant. To prevent the damage, fraud detection system (FDS) calculates the risk of the electronic payment transactions using user profiles including types of goods, device status, user location, and so on. In this paper, we propose a new risk calculation method using relative location of users such as SSID of wireless LAN AP and MAC address. Those relative location information are more difficult to imitate or copy compared with conventional physical location information like nation, GPS coordinates, or IP address. The new method using relative location and cumulative user characteristics will enable stronger risk calculation function to FDS and thus give enhanced security to electronic payment systems.

Maritime police recognize that the organizational culture of various acting as a member of the organization. Also, marine policing and security activities to determine the number of build. The overall culture of maritime police who share the organization sub-culture may take place. Maritime police organizational culture and a variety of types of group culture, hierarchical culture, development culture, rational culture examined the differences in perceptions. Maritime police aware of the general results of the analysis are as follows; First, the maritime police officers of the age group of 20 was the highest recognition in hierarchy culture and rational culture. Second, the maritime police officers of the rank of captain was the highest recognition in development culture and rational culture. Third, differences in the perception of organizational culture by recruitment analysis show the difference in cultural groups showed, in particular, the special recruitment group of police officers, and maritime police culture can be seen tend to appear low.

This study of transformational leadership impact on followership, job satisfaction and organizational commitment to investigate the relationship. Private security guards and managers that works private security firms located in Seoul, Gyeonggi-do, and Incheon in 2011 were set as a population and purposive sampling method to extract the sample by 880 people, but final samples of 790 people were drawn from the results. This study SPSSWIN 16.0 using factor analysis, reliability analysis, Pearson's Correlation Analysis, multiple regression analysis, path analysis was carried out. In addition, this study is to investigate the influence of transforming leadership with followership, job satisfaction and organizational commitment. The results are as follows. First, transforming leadership affects followership. Second, transforming leadership affects job satisfaction and organizational commitment. Third, followership affects partially In other words, behavioral tendencies increases job satisfaction and organizational commitment. Thinking tendencies is also job satisfaction and organizational commitment does not affect.

Earthwork planning is one of the critical issues in a construction process management. For the construction process management, there are some different approaches such as optimizing construction with either mathematical methodologies or heuristics with simulations. This paper propose a simulated earthwork scenario and an optimal path for the simulation using a reinforcement learning. For reinforcement learning, we use two different Markov decision process, or MDP, formulations with interacting excavator agent and truck agent, sequenced learning, and independent learning. The simulation result shows that two different formulations can reach the optimal planning for a simulated earthwork scenario. This planning could be a basis for an automatic construction management.

Artificial intelligence is closely linked to our real lives, leading innovation in various fields. Especially, as a means of transportation possessing artificial intelligence, autonomous unmanned vehicles are actively researched and are expected to be put into practical use soon. Autonomous cars and autonomous unmanned aerial vehicles are required to equip accurate navigation system so that they can find out their present position and move to their destination. At present, the navigation of transportation that we operate is mostly dependent on GPS. However, GPS is vulnerable to external intereference. In fact, since 2010, North Korea has jammed GPS several times, causing serious disruptions to mobile communications and aircraft operations. Therefore, in order to ensure safety in the operation of the autonomous unmanned vehicles and to prevent serious accidents caused by the intereference, rapid situation judgment and countermeasure are required. In this paper, based on big data and machine learning technology, we propose a countermeasure system for GPS interference that supports decision making by applying John Boyd's OODA loop cycle (detection - direction setting - determination - action).

The purpose of this study is to verify the mediating effect of rejection sensitivity and relationship addiction in the relationship between abandonment anxiety and psychological dating violence. For this purpose, data of 400 adult were collected and analyzed, and the structural equations were used to verify them. The measurement tools were the Abandonment Anxiety Scale, the Rejection Sensitivity Questionnaire Scale, Relationship Addiction Questionnaire-30 and Psychological Dating Violence Scale, which were the Revised Conflict Tactics Scales-2 and Appraisal of Partner Control Scale. The results of the study are as follows: First, there was a significant corelation among abandonment anxiety, rejection sensitivity, relationship addiction, and psychological dating violence. Second, there was no direct effect on the relationship between abandonment anxiety and psychological dating violence, but it had an effect on psychological dating violence by double mediating rejection sensitivity and relationship addiction. Based on these results, we confirmed the psychological path that abandonment anxiety affects psychological dating violence, and discussed the need for therapeutic intervention and educational approach in negative interpersonal patterns that are not visible.

The housing is basic need to human life, foundation of family life and structural characteristics to control human life and action. The structural characteristics of housing have various effects on the family life such as family lifestyle, relationship of family members and child development and health by family structure. The purpose of the study is to identify how the housing poverty, defined as sub-minimum standard housing conditions, excess housing expenditure and housing instability, affects the family responsibility burden, the family relationship satisfaction and the family life satisfaction. This study used the third Korean Welfare Panel Study, the analytic method used was the Structural Equation Modeling(SEM), and the model fit had a considerable validity by inspecting the SEM. The findings of the study are as follows. Housing poverty had significant positive effect on family responsibility burden, while had significant negative effects on family conflict action method, family relationship satisfaction, family life satisfaction and health(subjective, mental, physical). The indirect effects on housing poverty had better effect by family conflict action method than effect by health, but the direct effects had the most.
