  • This paper describes the Autonomous Vehicles (AV) which are operated for their own tasks. There are chances of conflict resolution such as sharing the same path which can lead to the risk of a collision. This research represents some ways of negotiating the conflict resolution by generating cooperative actions. Negotiation while traveling the path is accomplished by using priority and by announcing the start time of the task. When there is a risk of collision, the AV tries to dissolve the situation of conflict resolution by concurrently adjusting mutual speed and by performing the algorithm of passing. If the speed of the AV cannot be adjusted, it measures the distance between the counterpart of the AV and an obstacle along the path. Then it judges either to proceed by passing the counterpart of the AV or to turn back after observing the current circumstances. The performance of the algorithm described above was proven by a simulator.

  • Background: While the organizational factors that account for firefighters' burnout have been extensively explored, the individual factors related to how they regulate interpersonal conflicts and emotions remain to be investigated. Previous research has demonstrated the association between emotional intelligence and conflict management styles and burnout, but no study has looked at the interrelationships among these factors in high-risk sectors. The present exploratory study aimed to fill this research gap by investigating the relationships between conflict management style, emotional intelligence and burnout in a sample of firefighters. Methods: A cross-sectional study was conducted with 240 French firefighters. Measures comprised validated scales of conflict management styles, emotional intelligence and burnout. Results: Results showed that the integrating conflict style reduced burnout. They also revealed the effects of emotion regulation on burnout, whereby the awareness and management of one's own emotions reduced burnout. Moreover, awareness of one's own emotions moderated the relationship between integrating conflict resolution style and burnout, whereby the effect of integrating style on reduced burnout was higher when awareness of one's own emotions was high. Conclusion: These results reveal that strategies used by firefighters to regulate their emotions in order to meet the emotional demands specific to their job are important for reducing the emotional exhaustion component of burnout. Training programs for conflict and emotion management are needed to preserve the mental health of firefighters and ensure the safety of interventions.

A Study on the Application of PPLT(Protected/Permitted Left-Turn) Considering the Traffic Characteristics of PLT/PPLT (보호좌회전과 보호/비보호 겸용 좌회전 통행특성 차이를 고려한 보호/비보호 겸용 좌회전 적용방안에 관한 연구)

  • The application of PPLT is difficult to analyze and judge only from the effects of the delay time. In this study, the application of PPLT was proposed using not only the delay time of PLT and PPLT due to the change in traffic volume and the number of opposite straight lanes but also the traffic volume of passing a left turn and the number of conflict risks as indicators. According to the analysis, the more left-turn traffic than capacity and the less opposite-straight volume, the greater the PPLT effect. On the other hand, if the left-turn traffic is below capacity, the delay time will be reduced partially, but the overall passing left turn volume will not increase, and the conflict risk will increase. In addition, the conflict risk increases in the third lane or higher. Moreover, the difference of passing left-turn volume between PLT and PPLT showed a pattern similar to the delay time difference, and the PPLT coverage was wider than the difference in delay time and was associated more with the conflict risk numbers. Therefore, it would be reasonable to use passing left-turn traffic primarily, consider the delay time below the left-turn capacity, and consider the conflicting risk numbers simultaneously at or above the opposite straight three lanes.

  • A conflict of interest is usually defined as a set of circumstances that creates a risk that professional judgments or actions regarding a primary interest will be unduly influenced by a secondary interest. In general, a conflict of interest can be classified as either a financial or a non-financial one. A financial conflict of interest reportedly occurs frequently in medical (and psychiatric) research and practice and is associated with a greater likelihood of reporting results favorable to the intervention being studied. A non-financial conflict of interest may occur in psychiatric research and practice as a result of the so-called "allegiance effect." It is very important that clinicians and researchers in the field of psychiatry be aware that their field is vulnerable to both financial and non-financial conflicts of interest. Considering that it is impossible in modern psychiatry to be completely free from possible conflicts of interest, the best way to manage a conflict of interest is disclosure based on the principles of transparency. Actions that might lead to conflicts of interest should be avoided as much as possible.

  • The use of RPA (Robotic Process Automation) has been recently reviewed in various industries, but it seems that it is not being applied to companies faster than ever expected. In this study, three perceived risk factors affecting the acceptance conflict and acceptance intention of RPA technology were proposed and the effects of RPA on acceptance conflict and acceptance intention were investigated using RPA experienced people, gender and ICT industries as control variables. For the research, online survey was conducted targeting office workers and analyzed the results by using SPSS 22.0 and AMOS 22.0. As a result, it was found that among the three perceived risk factors, concern about introduction failure, employment insecurity, and execution errors, employment insecurity and execution errors did not affect the acceptance conflict and acceptance intention of RPA. This research shows that concerns over the introduction failure affected the acceptance conflict and acceptance intention. In addition, the acceptance conflict was judged as a factor of the mediation effect of the acceptance intention. From the perspective of companies that want to apply RPA, the theoretical and practical implications of business management are meaningful in that they can identify and respond to particularly important factors among perceived risks.

  • The conflict management of forest recreation, especially conflict management between hikers and MTB users, has drawn much attention as one of major issues in forest policy making. The main purpose of this study was to investigate hikers' conflict perception against MTB users and their attitudes toward the necessity of conflict management actions, and to identify factors influencing those attitudes. The research data were collected through online surveys of 644 men and women hikers who are aged 20 or older and not participating in MTB riding. The major findings of this study can be summarized as follows: First, the levels of goal interference and social value conflicts against MTB users were not so high, but rather, the awareness level of compatibility was much higher than that of conflict, and hikers' awareness level of safety risks posed by MTB users was also considerably high. Second, hikers' attitudes toward the necessity of conflict management actions were generally shown to be considerably positive, but those attitudes toward indirect management actions such as information, education, and compliance with norms of conduct, were significantly positive than those attitudes toward direct management measures such as zoning, enforcement, and regulations. Finally, the results of the multiple regression analysis showed that four factors that most significantly affect hikers' attitudes toward direct or indirect conflict management actions are behavioral norms conflict, safety risk, compatibility and age. Safety risks had most important influence on hikers' attitudes toward the direct management actions, but behavioral norms conflicts had most important influence on indirect management actions.

  • The downing of the MH17 reminds the world that the international civil aviation is not as safety and security as people expected. Such tragedy is partly due to the risk and danger of the armed conflict zones, but is more attributed to the ignorance to the international law by the responsible parties concerned. International laws applicable to the armed conflict zones shall be strictly followed, and the reparation shall be provided to the victims, otherwise such disaster could not be avoided in the future.

  • Objectives: The major objective of this study was to analyze stress response after a change to consecutive day shifts from day and night shifts in a motor assembly factory. Methods: Using a survey conducted by a labor union, we collected data on stress response index(SRI), lifestyle factors, work-family conflict and job stress before and after a shift system change. We analyzed the transition on the SRI among 222 workers. The cut-off point for the SRI was a T-score over 60. Results: The high risk stress response group was 20.3% of the population before the shift system change. After the shift system change it decreased to 11.3%. After the shift system change, social support improved, leisure time became more sufficient, work-family conflict declined, and sleep quality in the night shift week improved. In multivariable linear regression, among workers under 40 years old sleep quality on night shift, leisure time sufficiency, social support and work-family conflict contributed to the improvement of stress response. Among workers over 40, work-family conflict contributed to the improvement of stress response. Conclusions: The change to consecutive day shifts improved stress response and mediated with improved nighttime sleep, decreased work-family conflict, increased leisure time and improved work-family conflict.

  • Infrastructure development as national project suffers from social conflict which is one of main risk to be managed. Social conflicts have a negative impact on not only the social integration but also the national economy as they require enormous social costs to be solved. Against this backdrop, this study analyzes social conflict using articles published by online news media based on web-crawling and natural language processing (NLP) techniques. As an illustrative case, the Jeju Naval Base (JNB) project which is one of representative conflict case in South Korea is analyzed. Total of 21,788 articles and representative keywords are identified annually. Additionally, comparative analysis is conducted between the extracted keywords and actual events occurred during the project. The authors explain actual events in the JNB project based on the extracted words by the year. This study contributes to analyze social conflict and to extract meaningful information from unstructured data.

  • The purpose of this study was to inquire into how children's internet addiction is affected by home environments, computing environments, parental marital conflicts, parenting attitudes and parental monitoring and control as perceived by children. The study was conducted on 579 sixth graders at elementary schools located in Daejeon City. The data was analyzed by frequency, percentage, $X^2$, one way ANOVA, and scheffe analysis using the SPSS 18.0 version program. The results were as follows: first, out of 579 students, 5.0% were classified as at high-risk for addiction; 22.8% as at potential-risk; 72.2% as normal. Second, in the high-risk group, boys accounted for a higher percentage compared to girl students. Mothers' academic backgrounds and fathers' occupations affected the children's internet addiction. Third, the high-risk group tended to use the internet in internet cafes, to use it before going to elementary school, to use it for at least 4 hours once, and to use it to play games. Fourth, the high-risk group perceived parents marital conflicts as more frequent and more severer, as compared to other groups. Fifth, while the high-risk group perceived parenting attitudes as negative, the normal group perceived them as positive. Sixth, the potential-risk group and the normal group perceived parental monitoring and control as more frequent, as compared to the high-risk group.
