  • The Automatic Dependent Surveillance Broadcast (ADS-B) system is a key component of CNS/ATM recommended by the International Civil Aviation Organization (ICAO) as the next generation air traffic control system. ADS-B broadcasts identification, positional data, and operation information of an aircraft to other aircraft, ground vehicles and ground stations in the nearby region. This paper explores the ADS-B based trajectory prediction and the conflict detection algorithm. The multiple-model based trajectory prediction algorithm leads accurate predicted conflict probability at a future forecast time. We propose an efficient and accurate algorithm to calculate conflict probability based on approximation of the conflict zone by a set of blocks. The performance of proposed algorithms is demonstrated by a numerical simulation of two aircraft encounter scenarios.

  • Purpose : This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward. Methods : Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny's procedure. Results : Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found. Conclusion : To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

  • The building production system has been analysed by the dichotomy "employer-contractor" relationship, which failed to take into account of the role and function of multiple stakeholders within the life-cycle supply chain. This is further observed in the current conflict resolution model, which, in my argument, struggles to contribute to industrialize the building production and achieve better efficiency and effectiveness as expected. The purpose of this paper is to critically assess the issues of current programme-based conflict resolution model, and discuss alternative models how they can be modelled and applied to the construction projects. The conclusions of findings are; First, the current model is framed around the contracts and dispute resolutions based on the legal concept of "claimant and respondent" where one party(s) advances a claim once and the other(s) objects, as such it fails to reflect the nature of construction projects where multiple stakeholders are involved concurrently and for a long period of life-cycle of buildings. Second, an alternative is "Six-stakeholders model" which represents the multiple stakeholders and clarifies the flow of obligation-liability-monetary relationships among participants for a long period of life-cycle of buildings. Further, with reference to both historical and recent cases, a reflection and insight into pros and cons of programming method is added, especially as to why this method is considered to have become a mandate of the modern construction management, and how academics and practitioners should deal with it more cautiously and prudently.

  • Purpose: This study aimed at exploring the impacts of organizational conflict and job satisfaction on the turnover intention among dental technicians. Methods: This study utilized a descriptive research design. A structured questionnaire was administered to 159 dental technicians. Of the collected questionnaires, data from 127 valid questionnaires were analyzed using t-tests, analysis of variance, Pearson's correlation coefficient, and hierarchical multiple regression using the IBM SPSS 20.0 statistical package. Results: A positive correlation was identified between organizational conflict and turnover intention (r=0.46, p<0.001); however, a negative correlation was shown between job satisfaction and turnover intention (r=-0.50, p<0.001). A hierarchical multiple-regression model was employed to analyze working hours, unfair treatment from dentists and dental hygienists, organizational conflict, and job satisfaction, which contributed to providing an explanation to 39% of the turnover intention of dental technicians (F=14.16, p<0.001). Furthermore, organizational conflict (β=0.32, p<0.001), job satisfaction (β=-0.31, p=0.003), and working hours (β=0.21, p=0.010) were all shown to affect turnover intention. Conclusion: The impact of the negative consequences of organizational conflict and working hours on the turnover intention should be considered within core strategies for increasing the turnover periods for dental technicians.

  • Objective: The main purpose of this study was to examine the relationship between marital conflict, parentification, and adolescent anxiety. Methods: The participants comprised 301 high school students from the Seoul province. They were asked to complete questionnaires that consisted of the State-Trait Anxiety Inventory, the Children's Perception of Interparental Conflict Scale, and the Filial Responsibility Scale-Youth. The data were analyzed by frequency analysis, Cronbach's ${\alpha}$, descriptive statistical analysis, Pearson's correlation coefficients, multiple regression analysis, and hierarchical multiple regression analysis. To analyze the collected data, SPSS 18.0 was used. Results: First, the content and resolution of marital conflict had an effect on both adolescent state anxiety and trait anxiety. Second, unfairness parentification had an effect on both adolescent state anxiety and trait anxiety. Third, the frequency of marital conflict had an effect on emotional parentification. Further, the intensity, content, and resolution of marital conflict had effect on unfairness parentification. Fourth, unfairness parentification played a partial mediating role in the relationship between the content of marital conflict and adolescent anxiety (state anxiety/trait anxiety). In addition, unfairness parentification played a complete mediating role in the relationship between the resolution of marital conflict and adolescent trait anxiety. Conclusion: These results indicate that parentification plays an important role in marital conflict and adolescent anxiety. In addition, this study also shows that marital conflict has an important effect on adolescent anxiety directly. Therefore, this study will be useful for developing both parental education and counseling programs for adolescents.

  • This study examined the effect of interparental conflict and parent-child conflict on overt aggression in upper elementary school students and investigates if children's father-child conflict or mother-child conflict mediated the effect of interparental conflict on overt aggression. The participants of this study were 532 of fifth to sixth graders from three elementary schools located in Seoul and Gyeong-gi province. Participants were asked to respond to a written questionnaire to measure research variables of the Peer Conflict Scale, the Conflict Tactics Scales, and the Conflict Behavior Questionnaire. Data were analyzed by descriptive statistics and hierarchical multiple regression. Mediating effects were examined using analysis procedures of Baron and Kenny. The major findings were as follows: first, the level of interparental conflict and parent-child conflict of both mothers and fathers in upper elementary school students increased the level of overt aggression. Second, parent-child conflict of both mothers and fathers in upper elementary school students partially mediated the relation between interparental conflict and overt aggression. Higher levels of interparental conflict resulted in higher levels of parent-child conflict, and the subsequently higher frequency of overt aggression in upper elementary school students.

  • The purpose of this study was to investigate the relationship between parent's conflict, paternal/ maternal grandmother's psychological support and school-aged children's well-being. The subjects were 227 6th grade school-aged children in elementary school who were 128(56.4%) boys and 99(43.6%) girls. Instruments used in this research were CDI(Children's Depression Inventory), CPIC(The children's perception of interparental conflict scale), and psychological support scale. The data were analyzed by simple regression, standard multiple regression and hierarchical multiple regression(using SPSS 12.1). Major findings were as follows: (1) There was no difference in maternal grandmother's psychological support and paternal grandmother's psychological support. (2) Maternal grandmother's psychological support was more important variable affecting school-aged children's well-being than paternal grandmother's psychological support. (3) Paternal/maternal grandmother's psychological support operated as a main effect with school-aged children's well-being increasing as paternal/maternal grandmother's psychological support increased. There were not interaction effects of parent's conflict and paternal/maternal grandmother's psychological support on school-aged children's well-being. That result showed that paternal/maternal grandmother's psychological support did not moderate negative effects of parent's conflict on school-aged children's well-being.

  • Purpose: The purpose of this study was to identify the impacts of professional socialization perceived by nursing students on role conflict and professional self-concept. Methods: Using a structured questionnaire, data were collected from 683 nursing students. For data analysis, descriptive statistics, Pearson correlation coefficient, stepwise multiple regression were conducted using SAS program. Results: The mean score of total professional socialization was 3.74 followed by the scores of 'independence', 3.98, 'commitment', 3.80, 'decision making', 3.60, and 'maturity', 3.53. The mean score of total role conflict was 3.72, and professional self-concept was 2.75. Total professional socialization, commitment, and independence perceived by nursing students were positively related to role conflict. Also total professional socialization and total subcategories of professional socialization were positively related to professional self-concept. As a result of stepwise multiple regression analysis, the key determinants of role conflict were found to be 'independence', 'motivation with admission', 'sex', 'desire with working', 'grade' and 'decision making'. The key determinants of professional self-concept were 'decision making', 'commitment', 'satisfaction about nursing', and 'interpersonal relationship'. Conclusion: Through this results, it is necessary to improve professional socialization in order to increase professional self-concept among nursing students.
