One of the major causes is slow activityfrom experts on theoretical and practical management. In their decisions, they are not sufficiently ready to react todynamism of innovations in technical disciplines and current theory and practice in management. Contemporaryphilosophy of management is based on maximising quantity, expecting to deal with quality in due course.Management is focused on quantitative values and disregards the significance of the unity between quantity andquality. This leads to lack of transparency within management and uncertain efficiency of the decision-makingprocess. Disintegration affects the cooperation between individual production and administration branches. Theacademic world sees ethics more as a theoretical discipline connected with social sciences. Many companies,however, have begun to realise the need for innovation as part of successful long-term enterprising and creatingethical relationships inside and outside the company. Corruption scandals and increasing economic crime show thatit is counterproductive to advance business environment without adhering to moral and ethical principles.展开更多

In clinical practice, imaging-derivedtumor metrics are routinely applied in oncologic management as an imaging biomarker. For example, the ResponseEvaluation Criteria in Solid Tumors （RECIST） are commonly used for tumor treatment response evaluation based on thedynamic changes in tumor size. However, the current cross-sectional images are interpreted qualitatively for lesioncharacterization, treatment response evaluation and prognostic prediction by highly trained radiologists, which hasincreasingly apparent limitations. Therefore, there is a demanding shift toward more quantitative imaging interpretation.展开更多

The approach has three merits： （1） it optimizes both the route selected for service class by traffic engineering in network layer and the service class selected for the user services by network plan in service layer, （2） it ensures quantitative QoS for the user service in DiffServ, （3） it achieves high resource utilization, and achieves better performance with less cost for the user service and selected route. Simulation has verified these merits.展开更多
