Purpose: The purpose of this study was to investigate parent expectation and satisfaction with respect to pediatric inpatient care and to identify the variables related to parent satisfaction. Methods: The study was conducted in pediatric wards of a tertiary children's hospital in Korea. The participants were 361 parents of children who were inpatients. Data were collected using a structured questionnaire (The Pediatric Family Satisfaction Questionnaire) at the time of discharge. Results: The highest parent expectation domain was medical service. The parents were most satisfied with nursing service and least satisfied with general hospital service and accommodation. The parents expressed lower satisfaction with hospital facilities, equipment, noise, cleanliness, and communication by health care professionals. Parents with younger children reported higher expectation from the complete hospital service and those who had a longer length of stay reported higher expectation from the nursing service. Conclusion: To improve the quality of hospital services, we need to understand parent expectation and improve and provide clear communication. In addition, the general hospital service and accommodation should not be overlooked for improvement.

A new Computer Integrated Surgical Robot system is composed of a surgical robot, a surgical planning system, and an optical tracking system. The system plays roles of an assisting surgeon and taking the place of surgeons for inserting a pedicle screw in spinal fusion. Compared to pure surgical navigation systems as well as conventional methods for spinal fusion, it is able to achieve better accuracy through compensating for the portending movement of the surgical target area. Furthermore, the robot can position and guide needles, drills, and other surgical instruments or conducts drilling/screwing directly. Preoperatively, the desired entry point, orientation, and depth of surgical tools for pedicle screw insertion are determined by the surgical planning system based on CT/MR images. Intra-operatively, position information on surgical instruments and targeted surgical areas is obtained from the navigation system. Two exemplary experiments employing the developed image-guided surgical robot system are conducted.

Most organizations are more depending on information system in advanced information society. According to this current, unrapid reaction to system failure can cause a fatal effect to a credibility of the organization. An excessively high level of dependence on information system at work makes itself as a primary target of cyber terror. The stability of university's information system is especially weaker than the enterprise's but policy support for securing availability is inadequate. In this paper, we consider the recovery system toward to disorder of university's school affairs information system theoretically and suggest high availability PC based academic administration system.

This paper illustrates preliminary modeling for University Archives Management System(UAMS) construction. University must install Intermediate Archives(records and archives) facilities and management system by Public Records and Archives Act(PRA). But it is very difficult to generalize UAMS because University co-exists public and its own characteristic. For UAMS modeling, this paper first identifies University document's production creators and documental boundary. Then it is studied how University archives management is operated and what archives system by PRA means in University. Second systematic connection plan of Intermediate Archives(records and archives) facilities and manuscripts management is surveyed through National Universities and complementary things are presented. Finally through the above study UAMS model is suggested as future-oriented University archives management. UAMS model suggested from this study includes as follows. First manuscripts management as present Records and Archives system's standard function extension. Second manuscripts management system as system management area's extension using in Universities. It is desirable to extend to expert archives system. Finally integrated operating system model for using actively records, archives and manuscripts management systems operating in Universities.

We describe a calibration method to improve the accuracy of interferometric snapshot spectroscopic ellipsometry employing a dual-spectrometer sensor scheme. Conventional spectral wavelength calibration of a spectrometer has been performed by using a calibration lamp having multiple peaks at specific wavelength. This paper shows that such a conventional spectrometer calibration method is inappropriate for the proposed interferometric snapshot spectroscopic ellipsometry to obtain highly accurate ellipsometric phase information. And also, systematic error analysis of interferometric snapshot spectroscopic ellipsometry is conducted experimentally.

This paper presents a method for assessing reliability indices of transmission system. Because successful operation of electric power under the deregulated electricity market depends on transmission system reliability management, quantity evaluation of transmission system reliability is very important. The key point idea is based on that the reliability level of transmission system is equal to reliability level difference of between composite power system(HLII) and generation system(HLI). It is sure that risk indices of reliability of composite power system are larger than those of generation system. It is the reason that composite power system includes uncertainties and capacity limit of transmission lines. The characteristics and effectiveness of this methodology are illustrated by the case study using MRBTS.

This study analyzed the energy consumption of a building pump system that was originally equipped with a primary-secondary zone pump system. Using the HYSYS program the energy consumption of the primary pump system was compared with the primary-secondary zone pump system. The primary-secondary zone pump system consumes less energy than the originally designed primary pump system. When the distance between the machine room and each building is assumed to be equal, the primary pump system can be more efficient than the primary-secondary zone pump system with decreasing the distance. When the distance is 120 m, the primary system consumes less total annual energy than the primary-secondary zone pump system and saves 2,773 kWh. The suggested energy evaluation program can be useful if the designer seeks a more efficient pump system.

The challenge of predicting the Japanese coastal ocean motivated Frontier Observational Research System for Global Change (FORSGC) and the Japan Marine Science and Technology Center (JAMSTEC) to start a multiyear observational programme in the upstream Kuroshio in November 2000. This field effort, the Kuroshio Observation Program (KOP), should enable us to determine the barotropic and baroclinic components of the western boundary current system, thus, to better understand interactions of the currents with mesoscale eddies, the Kuroshio instabilities, and path bimodality. We, then, will be able to improve modeling predictability of the mesoscale, seasonal, and inter-annual processes in the midstream Kuroshio near the Japanese main islands by using this knowledge. The KOP is focused on an enhanced regional coverage of the sea surface height variability and the baroclinic structure of the mainstream Kuroshio in the East China Sea, the Ryukyu Current east of the Ryukyu's, and the Kuroshio recirculation. An attractive approach of the KOP is a development of a new data acquisition system via acoustic telemetry of the observational data. The monitoring system will provide observations for assimilation into extensive numerical models of the ocean circulation, targeting the real-time monitoring of the Japanese coastal waters.
