We present CReMeS, a CORBA-compliant design and implementation of a new real-time communication service. It provide for of a new real-time communication service. It provide for efficient, predictable, and scalable communication between information producers and consumers. Experimental results demonstrate that CReMeS can achieve better performance, predictability and scalability than a Real-Time implementaion of the CORBA Event Service.

In recent years, there have been emerging needs for standardized software-based motion application development for better scalability and support for multiple operation modes for small quantity batch production. Although a software-based motion system provides a basis for constructing multiple operation modes on a machine, it is not easy to construct such systems without tools for defining multiple motion operation modes and standardized mode-change protocols. This paper proposes a motion recipe concept to overcome this problem; the concept includes the authoring of multiple motion operation modes using the PLCopen-compliant motion function blocks and communication protocols to trigger operation mode changes from an external interface. The motion recipe was implemented by extending an IEC 61131-3 compliant IDE called Beremiz, and the correctness of the motion recipe-based application behavior was verified on a real testbed.

This paper deals with optimal mooring system to secure fish cage in a desired location, Through field investigation and paper works, we surveyed disasters by breakdown of cage frame and mooring system due to higher wave attack and selected compliant buoy mooring method for shallow water mooring system against severe coastal external forces. To analyze interaction between external forces and compliant buoy mooring system, theoretical model has developed as quasi-static nonlinear analysis. After verifying the feasibility of the numerical model compared with experiment, static analysis has tried for various mooring systems with different angle of array, number of mooring points, length of horizontal and inclined rope. Optimal mooring method using compliant buoy has selected for fish cage through numerical simulation. This results can apply for preliminary design for cage mooring system.

Purpose: This study was done to provide effective nursing interventions using an individualized educational program designed to contribute to the knowledge, compliance and physiologic parameters (serum potassium, phosphorus and interdialytic weight gain) of non-compliant hemodialysis patients. Methods: There were 22 participants in the experimental group and 19 in the control group. Nurses with rapport with patients provided education to non-compliant hemodialysis patients for 20 minutes three times a week for six weeks. This education program consisted of individual consulting, telephones conversations regarding hemodialysis, and requests for patient support from patients' families and colleagues. Results: Hypothesis 1; "Knowledge about hemodialysis in the experimental group will be higher than the control. group" was not supported. Hypothesis 2; "Compliance will be higher in the experimental group than in the control group", and Hypothesis 3; "Physiologic parameters of experimental group will improve" were supported as serum potassium and interdialytic weight gain decreased, but results were not consistent for phosphorous. Conclusion: This program for non-compliant patients increased compliance and improved physiologic parameters. Therefore, this educational program should be effective as a nursing intervention.

There are increasing needs to deliver the multimedia streaming over heterogeneous networks. When considering network environments and equipment accessed by user, delivery of video streaming must be scalable. There are many kinds of scalable video coding: spatial, temporal, SNR, and hybrid. The SNR scalable and spatial resolution, but different SNR quality with respect to layers. The 1-layer SNR scalable encoder produces SNR scalable video streams with ease. But, there is drift problem. Modified 1-layer approach does not have this problem but coding inefficiency, and is not MPEG-compliant. The present MPEG-compliant 2-layer encoder comes out to reduce coding rate. But it still use only base layer to encode whole layer. In this paper, we propose adaptive MPEG-compliant 2-layer encoder. Using linear combination algorithm, encoder use 1 motion vector to encode the sequences efficiently. By dong this, we can achieve the coding efficiency of SNR scalable coding.

The elastic recovery of a metal seal is a factor that can be used to assess its sealing performance. In this study, a compliant mechanism topology optimization has been performed to find a structure of a metal O-ring seal that can maintain excellent sealing performance with a maximized elastic recovery over extended operation. An evolutionary structural optimization (ESO) was used as a topology optimization algorithm with two different types of objective functions considering both flexibility and stiffness. In particular, a circular design domain was adopted to consider the outer shape of the metal O-ring seal. The elastic recovery of the optimal topology was calculated and compared to that of a commercial product.

ISO 26262 is an international standard for the functional safety of electric and electronic systems in vehicles, and this standard has become a major issue in the automotive industry. In this paper, a functional safety compliant electronic control unit (ECU) for an electric power steering (EPS) system and a demonstration purposed EPS system are developed, and a software and hardware structure for a safety critical system is presented. EPS is the most recently introduced power steering technology for vehicles, and it can improve driver’s convenience and fuel efficiency. In conformity with the design process specified in ISO 26262, the Automotive Safety Integrity Level (ASIL) of an EPS system is evaluated, and hardware and software are designed based on an asymmetric dual processing unit architecture and an external watchdog. The developed EPS system effectively demonstrates the fault detection and diagnostic functions of a functional safety compliant ECU as well as the basic EPS functions.

Although surgery is the mainstay of local treatment for skin cancer, definitive radiation therapy (RT) has been also applied for patients who are unable to tolerate surgery. Definitive RT regimens usually consist of daily treatment for 4-7 weeks. Such protracted daily RT regimens, however, would not be feasible for non-compliant patients or patients who are unable to make multiple daily trips for weeks. Without treatment, however, skin cancers can continuously progress and cause distressing symptoms. A cyclical hypofractionated RT (QUAD Shot: 14 Gy in 4 fractions, twice-daily treatments with 6 hours interval on 2 consecutive days) can be a practical RT regimen for those patients. In this report, we present the successful treatment course of repeated QUAD Shots in a 79-year-old patient with neglected skin cancer that was disfiguring his face yet declined definitive surgery and protracted RT. We also evaluated and compared biologically equivalent doses between QUAD Shots and conventionally fractionated protracted RT regimens.
