Venous thromboembolism, encompassing deep vein thrombosis and pulmonary embolism, has increased in cancer patients and adversely affects their prognosis. Low-molecular-weight heparins are recommended as efficacious and safe anticoagulation treatment in cancer patients. However, in practice, oral anticoagulation is preferred, especially if longterm or extended treatment is necessary. Novel oral anticoagulants have recently emerged as an alternative to the standard therapy owing to the ease of administration, predictable anticoagulation effect without the need of laboratory monitoring, and fewer drug interactions. These new agents have been shown as effective and safe for the management of cancer-associated thrombosis in ongoing head-to-head comparative trials. Here we review the advances and limitation of current anticoagulant therapies.

In this paper, we present a DSP-based high dynamic performance torque control scheme of variable reluctance motors(VRM's) for DD(Direct Drive) robots via function inversion technique. The VRM with our controller behaves like DC motors, and hence developed torque tracks given torque command accurately with no torque ripples. Furthermore, our torque control algorithm ensures the production of maximum constant torque under maximum current limitation, minimizes power loss in each phase resistance, and takes magnetic saturation effect into account. Also, since our control algorithm is represented in the form of look-up table, it can be easily implemented with simple digital circuits and this tabular design method is computationally more accurate and simpler compared to the prior methods.

Recently, it is reported that the behaviour of PECVD under high electric field and current condition has a major effect on MNS device degradation. In this paper, we evaluated the breakdown and TDDB characteristics of Laser assisted PECVD SiN films which is introduced new deposited method. And also, long term insulator breakdown reliability is described by examing time dependent dielectric breakdown under positive voltage. Failure tines against electric field are examined and acceleration factors are obtained for each case. From these data, breakdown wearout limitation for Laser Assisted PECVD SiN film can be characterized.

Understanding what lies beneath the relationship between ISP and its implementation is an significant area of inquiry in the ISP research. Through an empirical analysis and complementary case examples the current study examines this relationship at six different university sites which undergone both of these processes years from 1995 to 2001. The face-to-face, in-depth interviews were conducted to those participated in both of these processes. A questionnaire survey was also conducted to same participants to elevate the quality of the validity and reliability of the measures. Due to the limitation of the access to the data, it was not possible to compare how similar the final implementation outcomes are from what was originally planned in ISP to some sites. However the study finds that such organizational factors as management support, communication, and organizational culture at the ISP play an important role in the implementation process. This paper proposes that these organizational factors although little they seem to directly affect each individual elements in the implementation process, its latent impact is critical as a whole.

A repository has been conceived as a critical weapon for managing organizational information resources. The system can help control the heterogeneous data in a variety of CASE (Computer-Aided Software Engineering) tools. However, current repository systems have limitation in creating a synergetic effect by integrating information resources. Therefore, it is important to develop an integrative repository system, called Enterprise Repository System (ERS). This paper (i) defines ERS on the basis of a framework for repository systems, and (ii) suggests an ERS architecture and its detailed components. Finally, a real-life case of developing ERP repository system is illustrated according to the proposed architecture and components. This illustration may demonstrate the usefulness of this research for help developing an advanced repository system.

Graphene and Graphene oxide have intense interest in fields such as physics, chemistry, and materials science, among others. They are the promising material for solving the current limitation that organics have barely luminescence. We observed variation of photoluminescence on graphene oxide based solution with Gold nanoparticle. Gold nanoparticles lead to shift the peak wavelength of graphene oxide and to enhance the photoluminescence intensity totally. This shows the possibility that control the luminescence property of graphene oxide by adding gold nanoparticle.

We propose a hole-filling method to solve discontinuous depth representation and to reduce the visible seams and cracks that cause the limitation of the viewing angle of the three-dimensional (3D) image in the multilayer type 3D display system. The occlusion and the disocclusion regions between layers, such as the visible seams and cracks, are a major bottleneck of the multilayer type 3D display system to represent a volumetric 3D image by stacking multiple images. As a result, in the reconstructed 3D image, the visible seams and cracks appear as brighter overlapping and undesirable cut-off. In order to resolve the problems above, we applied the depth-fused effect to the sub-depth map generating algorithm and improve the viewing characteristics of the multilayer type 3D display. The experimental demonstrations are also provided to verify the proposed scheme.

Although companies perform societal marketing activities across different cultural regions, previous research was predominantly centered on a specific cultural region-the West. To address this limitation in the literature, the current research examines societal marketing in the Chinese market considering cultural characteristics. China has become the largest market in the world with great potential growth for its vast consumer base. Since there is heterogeneity among regions in China, it is imperative to divide China into several markets for better understanding. Thus, this study investigates different responses of Chinese regional (coastal vs. inland) consumers toward Cause-related Marketing (CM). Our findings reveal that Chinese consumers, in general, prefer utilitarian CM products compared to hedonic CM products, which is the opposite result of findings of the previous research. Further, this was truer for consumers in inland regions, while coastal consumers did not display any preference by product type. The academic and practical implications, limitations, and directions for future research are discussed.

We observed tidal currents throughout all four seasons in 2007 at a single station, located 1.6km off Haeundae Beach and compared these current data with wind data. The direction of seasonal wind represented a similarity between the winds at sea and on land but the speed of wind at sea was almost three times stronger than the wind on land. In addition, the wind at sea turned out to considerably affect on tidal currents, particularly from late summer to autumn. On the other hand, the thickness of Ekman Layer, indicating a limitation of wind influence, was estimated to be 31.8 m on average, suggesting that the entire water column is under the influence of wind. Therefore, we are required to consider the wind stress into the analysis of tidal currents for the prevention of the loss of sand from Haeundae Beach.

The purpose of this study is to investigate the development process and current status of income maintenance policies after the financial crisis, to sort out key issues or problems, and to explore future plans or directions that can overcome the limitation. In order to develop intensive argument, the scope of research is limited to the National Pension, Basic Pension, and the National Basic Livelihood Security System. The research also focused on two values of the 'universalism' and the 'adequacy' based on the 'SPF(social protection floor)' in the overall narrative process. Additionally, this paper briefly summarized the related contents released by the Moon Jae-in Government and presented an affirmative strategy and a transformational strategy centered on social allowance and basic income respectively, to establish an integrated income guarantee scheme. Although some improvements to the present system are also required, it is an effort to expand the practical effect of social benefits through the full and comprehensive reform of benefit structure and method.
