This research emphasized that the importance of work-family conflict elements such as time-based conflict, strain-based conflict, behavior-based conflict and verify the effects of these three elements on organizational commitment through the moderating effects of Job autonomy. The research results are as follows. First, behavioral-based conflict, a element of work-family conflict, was found to have a negative effect on organizational commitment, but time-based conflict and strain-based conflict were verified to have no effect. Second, strain-based conflict and behavior-based conflict, which are elements of family-work conflict, were found to have a negative effect on organizational commitment, but time-based conflict was verified to have no effect. Third, job autonomy had a moderating effect in the relationship between behavior-based conflict and organizational commitment. Fourth, as a result of verifying the moderating effects of job autonomy in the relationship between family-work conflict and organizational commitment, it was found that job autonomy had moderating effects in the relationship between strain-based conflict, behavior-based conflict and organizational commitment.

In this study, the investigator examined employees' work-family conflict, and analyzed its relationship with family health, to clarify the two-way influence of work-family and to verify the influence of a family friendship system based upon work-family compatibility and a healthy family. Data from 379 married female and male corporate employees were collected. Collected data were analyzed on the SPSS WIN 12.0 program. Study findings are as follows: First - For the individual, in domain variables of work-family conflict according to socio-demographic characteristics, gender has a significant influence upon strain-based conflict, family interference with work, and time-based conflict. Second - Work domain variables such as occupation, career, employment type, and working hours have a significant influence upon work interference with family, while career, and a working couple have a significant influence upon family interference with work. Finally - average housework hours and children have a significant influence upon work interference with family, whereas the length of a marriage, the average housework hours, and a housework helper have a significant influence upon family interference with work.

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.

Because of a wide range of performance and diversity of project and uncertainty caused by complexity and a number of stakeholder, conflict occur necessarily in Urban generation including large-scale and many project which do the same time, for long time. So active conflict management which recognized risk before the fact and deal with conflict is necessarily needed. This paper based on the conflict cases related an urban regeneration. In those cases, we proposed the reason of the conflicts by analysis the most frequent combination of the conflicts and a case of conflict between each group.

Conflict in public construction projects has increased for the last decades. It not only entails enormous social and economic costs but also makes stakeholders suffer from unnecessary expense and time waste. This study defines the the conflict index for public construction projects based on news data, and calculates conflict index for representative past and current public construction projects that has been deepened conflicts at the national level. The result indicates that the major conflict issue of the 2nd Jeju Airport Project are the environment and location whereas that of the Gaduk New Airport Project are the safety, location and necessity. This approach is expected to enable construction project managers to manage conflicts quantitatively based on comparing with past cases.

As organizations have come to be more complex and diverse, management has come to spend an increasing proportion of its time and efforts in handling organization conflict. Moreover, organizational conflict problems are often not recognized until the balance of interests is destroyed or a radical organizational change such as BPR takes place. Once an organizational conflict arises, however, it reduces corporate synergy seriously, leading to organizational ineffectiveness. Therefore, it is important to identify the cause of organizational conflict in advance and resolve it based on the proper diagnosis as early as possible lest it should undermine the organizational effectiveness. We propose a method that facilitates diagnosing potential organizational conflict and determining appropriate strategy to the conflict, based on the analysis of cognitive maps. To support the application of the method in the real world context, a computerized tool is introduced. The working procedures of the method and the features of the tool are illustrated with their application to the real case of the cable TV home shopping company.

The purpose of this study is to shed light on the effect of work-family conflict on organizational effectiveness, focusing on the moderating effect of organizational support among married working women of health services organizations. Data were collected from 149 married working women of health services organizations located in Busan Metropolitan areas by structured self-administered questionnaire. Main results of this study is as the following: First, based on the type of work-household conflicts, namely time-based conflict(2.82 points), strain-based conflict(2.81 points) and behavior-based conflict(2.69 points), working women mainly experienced time and strain-based conflicts. The level of work-household conflicts was significantly higher among younger groups, highly educated, nurses, and regular workers. Second, the perceived organizational effectiveness found to be an above-average. Especially scores were high in the subcategories of customer orientation(3.84), followed by organizational commitment (3.42) and job satisfaction(3.19). The level of organizational effectiveness was significantly higher among older groups, medical technician and administrative job holders, day-time workers, and higher income groups. Third, the results of the regression analysis on the effects of work-household conflicts on organizational effectiveness showed that strain-based conflicts have a significant negative effect on organizational effectiveness such as job satisfaction and organizational commitment. Fourth, organizational support found to have a strong controlling effect for strain-based conflicts on organizational effectiveness. Above results imply that practical family-supportive policies for lessening the work-household conflicts is crucial for enhancing organizational effectiveness in health services organization.

The purpose of this study is to investigate the effect of work-family conflict and social support on retention intention in married female nurses. Participants were nurses working in 5 general hospitals in C city and data were collected from September 1 to 15, 2017. Data were analyzed by t-test, one-way ANOVA, Pearson's correlation, multiple regression analysis using SPSS Win 23.0. Factors influencing retention intention were identified as following; time-based conflict, more than one child, charge nurse, support of a co-workers, managers' support, with 37.3% explanatory power. This study shows that time-based conflict has negative effect on retention intention, while support of co-workers and managers have positive effect. This result may be useful in developing new strategies for enhancing retention intention. Further research is needed to identify other factors affecting the retention intention of married female nurses.

A method of conflict detection and resolution is described by using simple geometric approach. Two VAVs are dealt with and considered as point masses with constant velocity. This paper discusses en route aircraft which are assumed to be linked by real time data bases like ADS-B. With this data base, all DAVs share the information each other. Calculating PCA (Point of Closest Approach), we can evaluate the worst conflict condition between two VAVs. This paper proposes one resolution maneuvering logic, which can be called 'Vector Sharing Resolution'. In case of conflict, using miss distance vector in PCA, we can decide the directions for two VAVs to share the conflict region. With these directions, VAVs are going to maneuver cooperatively. First of all, this paper describes some '2-D' conflict scenarios and then extends to '3-D' conflict scenarios.

Thisstudy presentsthe development of a fast-time airport surface simulator. The simulator usesthe output from a first-come first-served (FCFS) scheduler and has adopted one-dimensional dynamic model to simulate the movement of the aircraft on the surface. Higher collision risks situations in the airport surface traffic are analyzed to classify those situations into six cases. A conflict detection and resolution algorithm is implemented to maintain separation distance and to prevent deadlock. The simulator was tested with a scenario at the Incheon International Airport that contains 72 aircraft. Without the conflict detection and resolution, various conflict situations are identified. When the conflict detection and resolution algorithm is managing the traffic, it is confirmed that the conflicts are removed at the price of additional delays. In the conflict resolution algorithm, three prioritization strategies are implemented, and delayed aircraft count and average additional delays are compared. Prioritization based on remaining time or distance showed smaller total additional delay compared to choosing minimum delay priority for each situation.
