The basic objective of broadcast scheduling is to get the smallest length TDMA frame, where many nodes are allowed to transmit simultaneously in a single time slot in a conflict-free manner. The secondary objective is to maximize the number of such transmissions for maximum use of the channel. An Artificial Bee Colony (ABC) with ranking strategy is proposed in this paper for the broadcast scheduling problem. Our proposed method is very efficient for generating initial and neighbor feasible solutions. We can get the best number of time slots and transmission utilization comparing to previous researches.

This paper analyze the fee structures of digital music contents and the revenue sharing ratios that are now on-going debates in Korean digital contents industry. Especially we consider Korean situation where copyrighters and telecom companies have conflict of interest. We found two major results. First, the choice between the flat rate scheme and the usage-based rate scheme is not important to telecom companies and copyrighters. The important thing is that copyrighters should decide the revenue sharing ratio and given that telecom companies should decide the retail price. Consequently, this way can lead to win-win solutions between them. Second, the flat rate scheme affects the relationship between consumers and telecom companies. Under the flat rate scheme, telecom companies have more benefits than consumers. In the vertical integrated structure, particularly, this tendency is more severe.

Designers are frequently faced with multiple quality issues in injection molded parts. These issues are usually In conflict with each other, and thus tradeoff needs to be made to reach a final compromised solutions. The objective of this study is to develop an automated injection molding design methodology, whereby part defects such as warpage and weld line are optimized. The features of the proposed methodology are as follows: first, Utility Function approach is applied to transform the original multiple objective problem into single objective problem. Second is an implementation of a direct search-based Injection molding optimization procedure with automated consideration of process variation. The Space Reduction Method based on Taguchi's DOE(Design Of Experiment) is used as a general optimization tool in this study. The computational experimental verification of the methodology was partially carried out for a can model of Cavallero Plastics Incorporation, U. S. A. Applied to production, this study will be of immense value to companies in reducing the product development time and enhancing the product quality.

This paper describes the development of new feature positioning method which embedded into the top-down assembly modeling system supporting conceptual design. In this work, the user provides the geometric constraints representing the position and size of features, then the system calculates their proper solution. The use of geometric constraints which are easy to understand intuitively enables the user to represent his design intents about geometric shapes, and enables the system to propagate the changes automatically when some editing occurs. To find the proper solution of given constraints, the Selective Solving Method in which the redundant or conflict equations are detected and discarded is devised. The validity of feature shapes satisfying the constraints can be maintained by this technique, and under or over constrained user-defined constraints can also be estimated. The problems such as getting the initial guess, controlling the multiple solutions, and dealing with objects of rotational symmetry are also resolved. Through this work, the feature based modeling system can support more general and convenient modeling method, and keeps the model being valid during modifying models.

This study analyzes patenting practices in the pharmaceutical industry and the impacts of sequential innovation. The main argument of the research is that strategic patenting is common in the pharmaceutical sector and it is legal within the context of patent law. However, when these practices have negative effects on the competition process post-grant, the practices that are legal under patent law may come into conflict with antitrust laws, which are not applied. The study brings into question whether sequential patenting practices characteristic of the pharmaceutical industry encourage or discourage innovation, and moreover, the overall functionality of the patent system. Ultimately, the functionality of the patent system creates market incentives that neglect consumer, i.e., patient, welfare; potential solutions to deal with the shortcomings are discussed.

This study applicates one of the five elaborated functional analyses of Piotr Stztompka to the housewives’study. The four general assumptions of plurality, wholeness, integration and boundary of the simple system issue the eight specific solutions; reciprocity, exploitation, consensus, conflict, dependence, autonomy, isolation and structural context of the relationships among the various elements of the system. From the eight specific assumptions of the housewives’studies, we have found that many managerial subsystem studies see the housewives’relationships to other elements in their reciprocity, concensus, dependence and isolation characteristics. If the assumptions of autonomy and structual context are used to this kind of study, we can understand the housewives’problem and potential but as an active subject of their humanlives, not as a simply passive primary manager of the family, and we can find a new concept of the development to change the housewives’quality of life.

Recently companies have increased the new projects to improve and innovate the business process in order to adopt the advanced technologies such as IoT (Internet of Things), Big Data Analysis, Cloud Computing, mobile and artificial intelligence technologies for sustainable competitive advantages under rapid technological and socioeconomic external environmental changes. However, there are obstacles to achieve the project goals, corporate's strategy and objectives due to various kind of risks based on characteristics of projects and conflicts of stakeholders participated on projects. Hence, the solutions are required to resolve the various kind of risks and conflicts of stakeholders. The objectives of this study are to investigate the impact of the project governance, agency conflicts on the project success based on agency theory by using the statistical hypothesis testing the relationship among those variables. As a result of hypothesis testing, we could find that the project governance impacts positively on project success and negatively on the agency conflicts. Further, the agency conflicts impacts negatively on the project success. Finally, we could find that the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and team members impact negatively on the project success. Meanwhile, the project governance impact positively on the project success, negatively impact on the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and project team members. In order to increase the project success rate, the project governance institutions such as PGB (Project Governance Board), EPMO (Enterprise Project Management Office), PSC (Project Steering Committee) are needed to prevent or reduce the agency conflicts between project manager and team members.

This study seeks to measure the level and root causes of occupational and interpersonal conflicts between nurses and nurse aids against hospital doctors, in order to help increase motivation of both groups in their workplace and enable more effective nursing care to patients. 271 nurses and nurse-aids working in small- and medium-sized hospitals were therefore given a series of surveys on topics such as conflicts with doctors, communications, cause of conflicts and solutions. Analysis of the survey result shows that both nurses and nurse-aids share relatively similar level and causes of conflicts in their place of work; however, nurse-aids felt more stress when their responsibilities seem to be duplicated or blurred from those of doctors and nurses. When conflicts actually occur with doctors, both groups would first try to avoid it one way or another. Then, nurses would make others cave in or file complaints through union, while nurse aides would seek help from supervisors or try to meet them half way.
