Gastrointestinal cancers, including liver cancer, colorectal cancer, and stomach cancer, are the most common cancers in the world as well as in Vietnam, posing a leading threat to human health. The cost of treating these cancers is a major problem that burdens not only patients but also healthcare systems. The study aims to analyze treatment costs for the four most common types of gastrointestinal cancer nowadays.

This study summarizes a sample of the managers of the Iraqi cellular communications company with 84 employees. The company is a service organization responsible for providing integrated telecommunications services. As a management system that uses human, technical, material and financial resources, its size and value increase in line with technical progress. The demand for telecommunication services is increasing for several factors, the most important being the only means available to the majority and to the increase in population.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

The problem investigated is the potential gap between the rhetoric of the 'promise of e-business' versus the dynamics of enactment and impacts of ICT in practice in the social enterprise sector. The main contribution of the research is to identify the real development impact of lCT use by social enterprises by assessing the role of ICTs in achieving their goals. Its major finding is that SEs' social and business missions are inextricably linked .and their use of ICTs and benefits from it can be used as a proxy to assess ICTD. Thus SEs provide a new paradigm in the study of ICTD.

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

The present study draws from two major bodies of literature: (1) research on leadership, which recognizes the important role of leaders in driving organizational performance and that leadership style may differ across individuals; and (2) the MCS literature, including RM concepts, in which control systems are viewed as mechanisms to “assist the organization in managing its risk and to promote effective governance processes” (Krogstad et al., 1999, p.

Two major areas of the scorecard development process were identified as having much capacity for improving credit scoring models. These are the application of 1) better classifiers and 2) variable selection techniques. However, the application of an artificial immune system for developing scorecards as well as the use of other variable selection techniques, other than stepwise regression, in credit scoring are quite limited as indicated by the scarcity of published materials in these two areas in the current literature.

The world is becoming increasingly focused on an imperative to reduce the cost of services. Managers at this cutting edge of practical organizational development are trying many ways to achieve this. The major focus of this research uses a systems psychodynamic approach to investigate the role taken up by part-time contract managers in an Australian university. These part-time roles frequently fail in the longer term. This approach provides an understanding of the unconscious group dynamics that may cause the role to fail.

The Hellenic subduction system governs the entire Aegean region through the creation of a migrating magmatic arc that has existed since the beginning of the Early Cenozoic. The Karadağ Pluton is situated in the NW part of Turkey and represents one of the distinct snapshots of this subduction system during the Late Oligocene-Early Miocene Period.iod.

The Aegean region is one of the most seismically active regions in Turkey and comprises the Hellenic Arc, Greece, and Western Turkey. The Tuzla Fault, which lies between the town of Menderes and Cape Doğanbey, is one of the major seismic threats in western Turkey due to its seismic potential to generate a major earthquake (M 6, near Doğanbey Cape in 1992) and proximity to the city of İzmir which sustained damage due to the earthquake that occurred in the Aegean Sea on October 30th, 2020.

Gravity data inversion or interpretation requires the removal of the gravitational effects of the a priori known geologic and/or morphologic features within the Earth’s system to model and reveal the remaining signals of the unknown anomalous subsurface density distributions. The Bouguer gravity anomalies reduced by the normal gravitational field of the Earth and the gravitational attraction of the topographic masses above the sea level are frequently used in geophysics for this purpose.

Soil erosion strongly affects crop yield, undermines the long term productivity of farm land and sustainability of farming system, and poses a major threat to the livelihood of the farmers and rural communities. The United Nations Environmental Program reported that the productivity of soil has reduced and resulting in economically unfeasible cultivation on about 20 million hectare of land each year due to soil erosion and resulting degradation of land.

An understanding of soil microorganisms as part of soil system and interactions between the diversity of producers and of decomposers, have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil micro biota, existing in high density and diversity, rapidly modify the energetic performance and activity rates to changing environmental conditions.

This paper is an attempt to look at Vietnam’s current higher education system in terms of access and equity. Using logistic regression model and data from the Vietnam Household Living Standard Survey 2016, the paper also examines the factors explaining the enrolment in higher education in Vietnam. It shows that there has been a wide gap in the access between the rich and the poor, and between the Kinh/Hoa majority and the ethnic minority group in Vietnam. Therefore, public policies to assist disadvantaged groups getting access to higher education will be needed.
