A Typification of diagnosis and treatment(DT) model must be done in order to generalize the objective stage to the result of treatment to internal disease in connection with the type of viscera and bowel symptom. We could find 108 DT models in internal disease from the combination of 18 types of viscera and bowel and 6 types of DT treatment processes. Thus, the typification of 108 models of DT can be viewed as a modeling processes of utilizing DT knowledge at each stage. We argue that objectivity in diagnosis and treatment of internal disease can be obtained practically from typification of DT model.

Experimental results of the metal powder production with internal mixing, internal impinging and the atomizer coupled with substrate design are presented in this paper. In a test with internal mixing atomizer, mean powder size was decreased from $37{\mu}m\;to\;23{\mu}m$ for Pb65Sn35 alloy as the gas-to-melt mass ratio was increased from 0.04 to 0.17. The particle size further reduces to $16.01{\mu}m$ as the orifice area is increased to $24mm^2$. The micrograph of the metal powder indicates that very fine and spherical metal powder has been produced by this process. In a test program using the internal impinging atomizers, the mean particle size of the metal powder was decreased from $22{\mu}m\;to\;12{\mu}m$ as the gas-to-melt-mass ratio increased from 0.05 to 0.22. The test results of an atomizer coupled with a substrate indicates that the deposition rate of the molten spray on the substrate is controlled by the diameter of the substrate, the height of the substrate ring and the distance of the substrate from the outlet of the atomizer. This in rum determines the powder production rate of the spraying processes. Experimental results indicate that the deposition rate of the spray forming material decreases as the distance between the substrate and the atomizer increases. For example, the deposition rate decreases from 48% to 19% as the substrate is placed at a distance from 20cm to 40cm. On the other hand, the metal powder production rate and its particle size increases as the subsrate is placed far away from the atomizer. The production of metal powder with mean particle size as low as $3.13{\mu}m$ has been achieved, a level which is not achievable by the conventional gas atomization processes.

The paper is to study on the simulation of the micro/macroscale thermo-electrochemical model of a single cell of anode-supported SOFC with direct internal reforming. The coupled heat and mass transport, electrochemical and reforming reactions, and fluid flow were simultaneously simulated based on mass, energy, charge conservation. The micro/macroscale model first calculates the detailed electrochemical and direct internal reforming processes in porous electrodes based on the comprehensive microscale model and then solve the macroscale processes such as heat and mass transport, and fluid flow in SOFCs with assumption of fully-developed flow in gas channel. The simulation results evaluate the overall performance by analyzing distributions of mole fraction, current density, temperature and microstructural design in co/counter flow configurations.

In the context of globalization of information processes, the prevalence of information wars and terrorism, there are new threats to national interests in the information sphere, which actualizes providing the information sovereignty of modern states. Therefore, the purpose of the article is an in-depth analysis of the features and content of information sovereignty as a component of state sovereignty, its relationship with freedom of information and information security, as well as a characterization of the bases and directions of providing information sovereignty. The information sovereignty of the modern state includes its activities to determine national interests in the information sphere, the formation and implementation of information policy, providing information security, regulation and control of information processes. The realization of information sovereignty should be based on real freedom of information, information privacy and the state obligation to provide them. Ensuring information sovereignty also requires solving the problems of formation of modern information legislation, which would comprehensively establish the bases and directions of providing information sovereignty, exceptional cases of restriction of freedom of information.

Business processes are often of long duration, and include internal worker's decision making, which makes business processes to be exposed to many exceptional situations. These properties of business processes makes it difficult to guarantee successful termination of business processes at the design phase. The behavioral properties of business processes mainly depends on the data aspects of business processes. To formalize the data aspect of process modeling, this paper proposes a graph-based model, called Data Dependency Graph (DDG), constructed from dependency relationships specified between business data. The paper also defines a mechanism of describing a set of mapping rules that generates a process model semantically equivalent to a DDG, which is accomplished by allocating data dependencies to component activities.

The main purpose of this study is to define antecedents that influence e-SCM synchronization and to investigate how it affects e-SCM performance. We, therefore, investigate (1) the impact of firms' internal IT planning capabilities on e-SCM synchronization and on SCM process management capability, (2) the impact of firms' internal IT infrastructure on e-SCM synchronization and on SCM process management capability, (3) the impact of firms' internal SCM process management capabilities on e-SCM synchronization, and finally (4) the impact of e-SCM synchronization on SCM performance. A survey has been administrated to the firms' SCM and marketing staffs and 171 returns analyzed. The results show that (1) IT plan has not direct impacts on e-SCM synchronization, but has direct impacts on organizational support, purchasing, and operations processes except logistics process. IT plan, however, has indirect impacts on e-SCM synchronization through purchasing and operations of SCM process management capability. (2) IT infrastructure has both direct and indirect effects on e-SCM synchronization, and also has direct impacts on organizational support, purchasing, and operations processes except logistics process. (3) SCM process management capabilities have direct impacts on e-SCM synchronization. Among these SCM core processes purchasing positively influences operations, which in turn positively influences logistics process management capability. (4) e-SCM synchronization has positive impacts on SCM performance indicator (SCOR), such as delivery reliability, responsiveness & flexibility, and cost. These results indicate that e-SCM synchronization can be critical to achieve better internal performance like cost and external performance like delivery reliability, responsiveness & flexibility of firms' SCM. In sum, this study demonstrates that the intervening role of e-SCM synchronization between e-SCM performance and IT management capability and between e-SCM performance and SCM core process management capability has been significant in achieving better e-SCM performance. Therefore, it can be suggested that e-SCM performance should be accomplished in consequence of the acceleration of e-SCM synchronization through the enhancement of preceding factors for the e-SCM synchronization.

In the real world, business processes are very complex and composed or heterogeneous business activities. As the advent or the Web services enables business processes to be Integrated and to be automated. It makes enterprises integrate heterogeneous business processes from different business partners as well as their internal business processes. To support recent trends in integration of business processes, BPEL, WS-E and WS-T specipications have been established since 2002 WS-C and WS-T describe the reliable business environment including compensation (undo) or completed business processes. The compensation of business processes is a basic requirement for automation or business processes among business partners. Systems implementing these specifications, however, very rarely exist. It's not only because those specifications are developed recently. but also because they are not perfect yet. In this paper, a new business process transaction management, which complements the deficiency of WS-E and WS-T, is suggested. Furthermore, the new approach proposes the business logics for supervisory coordinators which manage serial and parallel business gates The modification or traditional WS-T specification and the simplification or WS-E specification make business processes managed effectively.

Most of bulk metal forming processes may be limited by ductile fracture such as surface or internal cracks developing in the workpiece. It is important to identify the conditions within the deforming workpiece which may lead to fracture, and then it is possible to modify the forming processes to produce sound and reliable product. This paper suggests the scheme to simultaneously accomplish prediction of fracture initiation and analysis of deformation in metal forming processes. The Cockcroft-Latham criterion which is successfully applied to a variety of loading situations is used in the present investigation to estimate whether fracture occurs during the deformation process. The numerical predictions and experimental results of two types of metal forming process are compared, axisymmetric extrusion and simple upsetting. The proposed scheme has successfully predicted the fracture initiation found experimentally.
