It is a common practice in Hong Kong for the main contractors of local building projects to sublet most of the work to subcontractors. Consequently their roles have gradually transformed from a constructor to a manager of subcontractors. The outcomes of a project therefore depend heavily on the subcontractors' performance. However, most of the subcontractors complain that they are unable to efficiently and effectively operate due to site coordination problems, such as inaccurate site reference lines, caused by main contractors. The site problems may consume significant amounts of resources if practical solutions cannot be agreed by the project participants early enough. Rahim Organizational Conflict Inventory-II (ROCI-II) model was developed by M.A. Rahim that measure five types of conflict management style including Integrating, Obliging, Dominating, Avoiding and Compromising. This paper presents the questionnaire survey based on the ROCI-II model to rank the preference on the conflict management style adopted by the project representatives of the subcontractors in handling the site coordination problems and its impact to the time used to agree the solutions to the different types of site coordination problems with main contractor. The survey results show that most of the subcontractors' project representatives preferred to adopt the Compromising style to tackle the site coordination problems and the time used to agree the solutions with main contractor was influenced by the conflict management style adopted.

The aim of this study is the optimization of the parameters of interconnected Hydro-Pneumatic (HP) suspension system of a three-axle vehicle for ride comfort and handling. For HP suspension systems of equivalent vertical stiffness and damping characteristics, interconnected HP suspension systems increase roll and pitch stiffness and damping characteristics of the vehicle as compared to unconnected HP suspension systems. Thus, they result in improved handling and braking/acceleration performances of the vehicle. However, increased roll and pitch stiffness and damping characteristics also increase roll and pitch accelerations, which in turn result in degraded ride comfort performance. Therefore, in order to improve both ride comfort and vehicle handling performances simultaneously, an optimum parameter set of an interconnected HP suspension system is obtained through an optimization procedure. The objective function is formed as the sum of the weighted vertical accelerations according to ISO 2631. The roll angle, one of the important measures of vehicle handling and driving safety, is imposed as a constraint in the optimization study. Upper and lower parameter bounds are used in the optimization in order to get a physically realizable parameter set. Optimization procedure is implemented for a three-axle vehicle with unconnected and interconnected suspension systems separately. Optimization results show that interconnected HP suspension system results in improvements in both ride comfort and vehicle handling performance, as compared to the unconnected suspension system. As a result, interconnected HP suspension systems present a solution to the conflict between ride comfort and vehicle handling which is present in unconnected suspension systems.

This study sought to find out the impact of conflicts in social welfare organizations on job performance and to find out the effects of controlling participatory decision-making in their relationships. To that end, a survey was conducted on workers at social welfare centers in Seoul, Gyeonggi Province and Chungcheong Province, and 360 copies were finally used for analysis and Correlation and hierarchical regression and statistical significance analysis of the adjustment effects were performed. As a result, conflicts within the organization, job performance, and participatory decision-making showed a negative correlation, and as participatory decision-making in the relationship between conflict within the organization and job performance showed a controlled effect, the impact of conflicts within the organization on job performance was reduced. These results suggest that participatory decision-making can alleviate conflicts within an organization and at the same time increase job performance. Based on this, the following suggestions were proposed: They include conflict management strategies in the guidelines for social welfare subjects, establish guidelines for conflict management, provide training for workers, engage workers in employee evaluation and compensation system development, and operate permanent organizations such as the Conflict Handling Committee after investigating conflicts within social welfare organizations.

The purpose of this research is to examine and analyze the effect of Relationship Marketing on service quality and customer loyalty, especially in the context of the retail industry. In retail industry, Relationship Marketing is the key to increase and maintain a large pool of customers. This research was conducted in North Sulawesi Province with a sample size of 155 supermarket customers. The sampling technique used for the study is the purposive sampling. Data was analyzed using SEM based on GeSCA components. The results showed that Relationship Marketing had a significant positive effect both on service quality and customer loyalty. The commitment, communication, conflict handling, and competence play an important role in improving service quality which ultimately makes customers loyal. In addition, the relationship between service quality and customer loyalty, also has significant positive findings. These findings are in line with the concept of SERVQUAL and The Commitment-Trust Theory. The implication of the managerial research is that supermarket managers in North Sulawesi must focus and emphasize more on the Relationship Marketing dimension especially in terms of commitment, communication, conflict handling, and competence. Once these factors can be met, the quality of service will increase, and it causes an increase in customer loyalty to shop more at the supermarket.

Purpose: This study aimed to test a proposed structural equation model in which bullying experience, conflict management styles and psychological empowerment predict psychological well-being among Chinese nursing students in clinical placement. Methods: Three hundred and sixty-six nursing students recruited from five hospitals in J city and Y city were assessed with self-report questionnaires on bullying experience, conflict management styles, psychological empowerment and psychological well-being including depression, self-esteem, and academic major satisfaction. Data were analyzed using SPSS version 20.0 and AMOS version 22.0. Results: The evaluation parameters included the comparative fit index at .90, the goodness of fit index at .93, the root mean square error of approximation at .07, and ${\chi}^2/df$ ratio at 2.66, indicating that the proposed structural equation model provided a good fit to the data. Experience of being bullied during clinical placement, conflict management styles and psychological empowerment explained 93.0% of the variance and had significant effects on psychological well-being, with conflict management styles and psychological empowerment mediating the association between bullying and psychological well-being. Conclusion: The findings indicated that mediation by conflict management styles and psychological empowerment alleviated the negative influence of bullying on psychological well-being. To limit bullying and its negative effects, development of effective guidelines to deal with bullying will be a critical tool for both Chinese nursing students and their instructors. Further research should incorporate conflict management styles and psychological empowerment into the specific intervention strategies for handling bullying behaviors among nursing students and staff nurses and promoting nursing students' psychological well-being.

Active suspension controls stiffness and damping between unsprung mass and sprung mass in order to increase the ride quality. However, to increase the riding quality, the handling quality should be decreased and the rattle space should be increased. So, active suspension should cope with these conflict conditions. Therefore its actuating devices have to produce sufficient actuating force and have sufficiently short response time. In this paper, the dynamic characteristics of 1/4 car model with an active suspension is studied according to hydraulic design variables. The active suspension consists of a hydraulic servo valve and a hydraulic cylinder. It shows better performance when it has more powerful and faster actuator.

A two-degree-of-freedom quarter-car model is used as the basis for LQ and the proposed controller design for a semi-active suspension. The LQ controller results in the best rms performance trade-offs(as defined by performance index) between ride, handling and packaging requirements. In LQ controller, however, the conflict between road holding and ride comfort remains. The adaptive semi-active suspension control based on the road frequency are introduced in this paper. With this method, the trade-off between road holding and ride comfort can be relaxed. The road frequency is estimated by wavelet transform if rattle space signal. The simulation results show that the proposed controller is superior to the conventional LQ controller.

Nowadays, Distributed Denial of Service (DDoS) attacks have gained increasing popularity and have been a major factor in a number of massive cyber-attacks. It could easily exhaust the computing and communicating resources of a victim within a short period of time. Therefore, we have to find the method to detect and prevent the DDoS attack. Recently, there have been some researches that provide the methods to resolve above problem, but it still gets some limitations such as low performance of detecting and preventing, scope of method, most of them just use on cloud server instead of network, and the reliability in the network. In this paper, we propose solutions for (1) handling multiple DDoS attacks from multiple IP address and (2) handling the suspicious attacks in the network. For the first solution, we assume that there are multiple attacks from many sources at a times, it should be handled to avoid the conflict when we setup the preventing rule to switches. In the other, there are many attacks traffic with the low volume and same destination address. Although the traffic at each node is not much, the traffic at the destination is much more. So it is hard to detect that suspicious traffic with the sampling based method at each node, our method reroute the traffic to another server and make the analysis to check it deeply.
