Cheng, Kuang-Ching 25 July 2001 (has links)
The ISO 9000 series of standards for international quality control and quality assurance, released by the International Standard Organization (ISO) on March 15, 1987 for establishing universal quality standards as a basis for international division of administrative responsibilities, had caught international attention. The second edition of ISO 9001-9003 standards was revised and released in 1994 to address the transition in entrepreneurial environment. The third edition of ISO 9001 standards was further revised and released on December 15, 2000. The manufactory and construction industries have demonstrated significant outcomes in improving corporate cultures and systems, reducing cost while increasing productivity, enhancing quality and market competition, and gaining clientele satisfaction after investing in vast amount of human resources and funds to introduce the ISO. The healthcare organizations had been less cognizant of the ISO series. The comprehensive national health insurance, which has been put into practice for six years since March 1995, has forced the healthcare organizations into fierce competitive edge. Hospitals take client-satisfaction as a competitive advantage for ongoing management and survival by providing higher quality medical services. This study investigates a case of hospital experiences in establishing international quality assurance system, such as : the definition and content of ISO, the reasons for establishment, education and training, control policy for persistence, auditing and perpetual improvements. Further, a detailed introduction is given following a review of literature to depict the successful experiences of the case hospital. Through surveys and interviews, practical knowledge and applicable experience can be identified. It is firmly believed more hospitals and healthcare centers will adopt ISO and benefit from adoption. The research findings are as follows : 1. Promoting ISO motivates hospital quality management and increases client confidence and satisfaction. 2. Success to certification basically lies in decisiveness, supportiveness of high-level management, and consensus among staff. 3. Most common obstacles in certification process are : insufficient manpower, heavy workload, and employee repulsiveness. 4. Perpetual participation in quality control practices is based upon leadership and team cooperation. 5. Significant improvements are demonstrated in standardization of documentation and workflow and elevation of management levels. 6. Hospital induction requires the management emphasis, educational training of the employees, accumulation of ISO-relevant information, and in-field observation of certified and successful hospitals. Keywords : ISO 9000s, healthcare management system, quality assurance

Abstract In order to make the limited manpower of judges concentrated on the core trialaffairs for the decrease or avoidance of the delay of cases, Judicial Yuan positivelypromote the Judicial Process Management System. Judicial process management isoriginally a system developed for the decrease of cases under delayed trial. Its centralthinking is that the judge will not start to intervene the trial until the case is close to thestage suitable for bringing to trial. The preparation work before that is to be positivelyhandled by a small number of judges and sufficient auxiliary manpower led by them. Asa result, the limited manpower of judges is able to concentrate their time and energy on oyer and judgment. Hence, the cases can be rapidly under trial, alleviating the caseburden of judges. This system has changed the traditional case separation model.Therefore, as from May 1, 2007 and June 1, 2007, Kaohsiung District Court and TaoyuanDistrict Court respectively started adopting this system to conduct trial handling of civilcases and criminal cases, with a trial period lasting for two years. In view of the localityfactor, and focusing on the Judicial Process Management System applied by Kaohsiung District Court to the handling of cases, the study just obtains materials from the localsources, and ttempts to employ the management implication to carry out this research,intending to construct a Judicial process Management System which is applicable to thecourts of Taiwan. Attempting to start the research from the angle of management, this paper adoptsthe research methods of literature analysis method, in-depth interview method and synthetic induction method, and combines them with multiple case analysis method to investigate and analyze the related problems. In the past, the judicial circle enormously stressed the cultivation of legal personnel and expertise, but obviously neglected the judicial administrative management. Along with the acceleration of reform steps, it is required to import administrative management system to the judicial circle. Focusing on the current predicaments of judicial administrative management in Taiwan, including the obstruction coming from the internal personnel and the restriction of external ordinance system, the study makes the related analyses, and expects to have an insight into the problems through the improvement way of the use of the readjusted human resources. The study pays concerns for, expands and increases the functions of legal supporting staff, and establishes the handling process of the judicial cases of Taiwan and the standard process of the time limit. Apart from absorbing the experience of the international advanced countries, the study cautiously and seriously considers the judicial culture itself in Taiwan, as well as the merits and demerits found in the cultivation restrictions of legal personnel. These two aspects are mutually integrated, hoping to bring greater progress to the judicial management policy of Taiwan, and turn it to be more complete. The construction of an efficient judicial institution has to be added with appropriate manpower and equipments. As observed from the experience of trial implementation of Judicial Process Management System, if it is hoped to pursue a rapid handling of cases, all the cases entering the court have to be strictly controlled, and promptly arranged to enter the trial procedures. The judges will not start to intervene the handling of cases until it is close to the stage suitable for bringing a case to trial. The study employs the concept of corporate operation management to promote Judicial Process Management System. The cases are to be handled by means of layering of team and division of labor. Let the human resources of the court perform the most effective distribution and use. In this way, the problems of serious accumulation of cases and poor efficiency of the trial of cases in different courts of Taiwan can be readily solved. In addition, to meet the concrete and objective conditions of the various courts of different grades in Taiwan, Judicial Process Management System has to be redesigned to meet the judicial process and methods of the local courts. Before the appearance of more positive and effective method, Judicial Process Management System can play a significant role in the process of judicial reform.

Konzeption und Entwicklung eines Probandenmanagementsystems am Beispiel der Universitätsmedizin Göttingen / Design and Development of a Participant Management System for the University Medical Center Göttingen

Schwanke, Jens 01 December 2015 (has links)
In medizinischen Forschungsprojekten besteht ein großer Bedarf an effizienter und einheitlicher Verwaltung sowie langfristiger Nachverfolgung von Probanden. Dieser Bedarf entsteht in Deutschland unter anderem aus der enger werdenden Verbindung von Versorgung und Forschung, der zunehmenden Vernetzung der medizinischen Forschung, sowie der Etablierung neuer Einrichtungen, wie beispielsweise Biobanken an Universitätskliniken. Im Rahmen dieser Dissertation wurde am Beispiel der Universitätsmedizin Göttingen untersucht, ob die Einführung eines Probandenmanagementsystems den Bedarf von Forschern an Effizienz, Einheitlichkeit und Langfristigkeit erfüllt. Im ersten Schritt wurde eine Anforderungsanalyse durchgeführt. Grundlage dieser Analyse bildeten 17 Interviews mit Stakeholdern der Universitätsmedizin Göttingen. Darunter befanden sich Ärzte, wissenschaftliche Mitarbeiter, Studienassistenten sowie IT-Verantwortliche. Anhand der Interviews wurden 16 Ziele an ein Probandenmanagementsystem formuliert. Auf Basis dieser Ziele wurden neun Szenarien modelliert, welche Interaktionen mit dem Probandenmanagementsystem beschreiben. Ziele und Szenarien sowie eine Literaturrecherche dienten anschließend zur Identifizierung der lösungsorientierten Anforderungen. Insgesamt wurden 30 funktionale Anforderungen, sieben Qualitätsanforderungen und neun Randbedingungen identifiziert. Die identifizierten Anforderungen bildeten den Ausgangspunkt zur Entwicklung des prototypischen Probandenmanagementsystems. Durch den entwickelten Prototyp werden 23 funktionale Anforderungen, zwei Qualitätsanforderungen sowie vier Randbedingungen direkt erfüllt. Die übrigen Anforderungen konnten aufgrund ihrer Komplexität oder wegen fehlender organisatorischer Randbedingungen nicht erfüllt werden. In der nachfolgenden Validierung wurde geprüft, inwieweit das Probandenmanagementsystem die Erwartungen der Stakeholder erfüllt. Um dies zu untersuchen wurde ein Usability-Test mit zehn Stakeholdern durchgeführt. Insgesamt bewerteten die Stakeholder das entwickelte System sehr positiv. Alle Stakeholder brachten im Anschluss an den Usability-Tests den Wunsch zum Ausdruck, das Probandenmanagementsystem für ihre Forschungsprojekte zeitnah nutzen zu können. Aktuell wird das System in drei Forschungsprojekten an der Universitätsmedizin Göttingen eingesetzt. In dieser Dissertation konnte so gezeigt werden, dass mit der Einführung eines Probandenmanagementsystems der Bedarf an effizienter und einheitlicher Verwaltung sowie langfristiger Nachverfolgung von Probanden erfüllt wird.

Optimering av solcellssystem och implementering av ett Energy Management System : Möjligheter för ett framtida bostadsområde

Marstorp, Jonathan, Trolle, Sten January 2015 (has links)
Riksbyggen, one of Sweden’s largest real estate companies, are planning to build a new residential area outside Uppsala, Sweden. Adjacent to the houses in the area, Riksbyggen are considering installing a 137 kWp photovoltaic (PV) system to supply the residents with renewable energy. In the first part of this study, the proposed PV system is analyzed based on benefits and profitability for the residents, using the software HOMER. Possibilities for including 3 kWp roof-mounted PV systems with varying azimuth as a complement to the larger system are evaluated. In the second part, options for implementing an Energy Management System (EMS) with battery storage or load shifting in the distribution grid using MATLAB. The system uses forecasting of PV generation, electricity prices and electricity demand to optimize the system control strategies. The results from the study indicate that installation of the 137 kWp PV system could lead to reduced average electricity costs of 21,1 % for the residents. If the system is completed with roof-mounted PV modules of varying azimuth for 12 % of the households in the area, the average electricity cost is reduced by 29,4 %in total. Implementing an EMS with energy storage in the distribution grid was not found to be an economically viable option, mainly due to high energy storage costs. The system control strategies can be improved by using forecasting. The economic benefits of load shifting for a single household were found to be too low to give incentive for system investment.

A delayed response policy for autonomous intersection management

Shahidi, Neda 14 February 2011 (has links)
The DARPA Urban Challenge in 2007 showed that fully autonomous vehicles, driven by computers without human intervention on public roads, are technologically feasible with current intelligent vehicle technology [6]. Some researchers predict that within 5-20 years there will be autonomous vehicles for sale on the automobile market. Therefore, the time is right to rethink our current transportation infrastructure, which is primarily designed for human drivers, not autonomous vehicles. The Autonomous Intersection Management (AIM) project at UT Austin aims to propose a large-scale, real-time framework to be a substitute for current traffic light and stop signs. Automobiles in modern urban settings spend a lot of time idling at intersections. In 2007, US drivers wasted 4.16 billion hours of their time and 2.81 billion gallons of gas in congestion, costing a total of 87.2 billion dollars nationwide [18]. A big portion of this waste takes place at intersections. The AIM project is able to utilize the capacity of intersections to minimize time waste and fuel consumption. The fundamental idea of Autonomous Intersection management (AIM) [13] is a reservation system in which cells in space-time will be reserved by the au- tonomous vehicles based on their trajectories. An intersection manager takes care of the reservation as well as communication with the vehicles. This mechanism tries to maximize the usage of the intersection area. It ensures a collision free intersection as well. The main question of this project is what intersection control mechanism is appropriate for reducing an autonomous vehicle's waiting time and improving the throughput of the intersection. Previous work proposed the first-come-first-served (FCFS) policy in which the reservation requests are served as soon as they are received. The results of simulation show that FCFS outperforms the current traffic systems, traffic light and stop sign, by orders of magnitude. We, however, observe that FCFS performs suboptimal in certain traffic patterns that are pretty common in urban settings. In this project, first we study the limitations of FCFS, then develop a more efficient policy to alleviate these limitations. The idea that we examined is a systematic policy of granting reservations that have the objective of minimizing the cost of delaying vehicles. In an attempt to build the system in reality, we used miniature robots called Eco-be. Due to their cost and size, Eco-bes are good candidates for testing a multi-agent system with a large number of agents. In spite of the fact that the physical challenges of Eco-bes do not perfectly match those of full size autonomous vehicles, they are still useful for demonstration and education purposes as well as for the study of collisions for which experiments with full size vehicles are costly and dangerous. / text
