  • A special cause producing temporary deviation in the underlying process can influence on process adjustment in First-Order System feedback control system. In this paper, the impact of special causes on the forecasts and the process adjustment that is based on the EWMA forecasts are derived for a first-order system. For some special causes with patterned type of contamination, the influence of the causes on the output process are explicitly investigated. A data set, contaminated by a special cause of level shift, is analyzed to confirm the impact numerically.

  • Design-Build (DB) has gained in popularity in roadway projects due to its defining advantage to improve communication and fast-track project delivery. However, very little is known about the impact of change order frequency and occurrence timing pertaining to DB projects. The study analyzes their impacts on project time and cost performance by conducting a rigorous numerical analysis drawing on 530 3R (rehabilitation, reconstruction, and resurfacing) projects completed between 2002 and 2011 in Florida by using a multiple linear regression. The results indicate that DB outperformed Design-Bid-Build in project cost as well as time. Critically, the regression analysis signifies that earlier change order occurrence caused more unfavorable impacts on schedule and cost. The proposed analyses and models will lead to the improved ability of agencies to quickly and more reliably estimate the potential change order impacts on schedule and cost.

  • Because of three reasons: rare natural resources, high dependent ratio and rapid wage increases, Korea must take the non-price competitive strategy. The developing process of quality management system in Korea can be categorized into five stages according to changes in economic policy. In order to develop the Korean quality management system effectively, we should try to connect total quality management with management system and emphasize the training and education.

  • The purpose of this study was to analyze characteristics such as spatial composition, areas, location of functional unit space and comparing the type and the number of operating programs by type of managements of multipurpose senior center in Youngnam metro area. first, the consignation management facilities had functional unit space of 152 things and the direct management facilities had 115 things. When comparing average areas composition ratio, direct management is public welfare, social education, public part, medical and rehabilitation order and consignation management is public part, social education, public welfare and rest part order. Second, medical part must be located around the first floor or the elevator, because many people can frequently use this area at the same time. Third, as a result of analysis of management programs indicated that the total number of programs is as a whole 74 things a range of $min12\~max20$ in the each direct management facilities and 111 things a range of $min20\~max24$ in the each in the each consignation management facilities. This fact shows that consignation management provided many people with more various programs than direct management. Finally, the number of staff in the direct management is less than consignation management. When comparing programs per staff and space, the direct and consignation management each appeared (2.74, 0.64) and (1.35, 0.73). This fact implied that the consignation management was more specialized than direct management in the service and function.

  • The relatively recent emphasis on a total allowable catch(TAC) system is placing new demands on fisheries management. Korean fisheries law has provided recently for implementation of the TAC based on fishery management system, in order to conserve and manage fisheries resources rationally in its exclusive economic zone(EEZ). In 1998, the TAC system was first applied to Korean fisheries. This TAC system is currently undergoing a second trial period, having been put under the system for 20012002 and continuous trial basis until the complete settlement of EEZ system agreement among three countries, Korea, China and Japan. The TAC system implementation needs are sophisticated information collection, analysis and modeling that will continue to increase and require the high management resources. In addition, data on social and economic impacts on TAC system is sometimes inadequate. The implementation of the TAC system provides a unique opportunity to examine the limits of management information and resources, and to solve the problems in Korean fisheries management system, These limits and problems are complicated by an inadequate biologically and economically information and insufficient management resources. Government and fisheries cooperatives must be cooperated in the management process in order to minimize its conflicts and maximize commitment to sustain fishery development. Recognition of the ineffectiveness and its potential consequences leads to the adoption of the cooperative-based co-management approach in implementation of TAC system. In 1998, the TAC system was first applied to Korean fisheries, where traditional fishery management has consisted mainly of technical measures and input controls. The QMS of TAC system has been implemented in the form of cooperative-based co-management framework. This QMS framework was chosen to overcome many difficulties and limits that a competitive TAC system would impose on Korean traditional fisheries management. The implementation of the QMS of TAC system provides a unique opportunity to examine the limits of management information and resources, and to solve the problems in Korean fisheries management system.

Because these kind of resources determine efficiency of kitchen management, human resource management is important aspect of kitchen operation. In this paper of view, recently human resource management has been considered by kitchen manager. Kitchen Managers who are interested in human resource, focus on efficiency. Also human resource management underlined not only efficiency, but interrelationship of emplyee. Today, considering with the environment of management, operation of kitchen is important section on hotel management in relation to the profit of it. In the future, therefore kitchen will be strategic profit center on hotels. According to in this tendency, as profit business center kitchen assumed a aspect of efficiency mechanism. This thesis aimcs to point out the actual status of human resource management in the hotels, and suggests the improvement there of by analyzing the system. This research is organized into five sections. section one introduces its objectives. scope and mothodology. Section two provides the theory of human resource management on the kitchen of hotels. And section these analyzed about the factors of human resource management. Section four, suggests the alternatives of the improvement on human resource management, section Five describes the conclusion of this thesis. Today, importance of human resource is viewed multipoint aspects in relation to efficiency of organization and interrelationship of employee, especially the arrangement of human resource is fairly handle and allocation of the human resource and personal appraisal. On the other hand, human resource managers have to be responsible for the cost control and customer's attraction by developing human resources. In order to advance human resource management on kitchen of hotels, following alternatives are considered with efficiency of management and interrelation of employee. The first, the manager of hotels has to consider the passive support of development of human resource. The second, the manager of hotels should develop the various training program for the extonsive ability of employee. The third, in order to improvement of human resource management, manager should establish the system for human resource management view of efficiency and employee's interrelationship.

  • Health management system of airborne software repairs runtime errors to provide safety and to reduce cost of maintenance. It is critical to on-the-fly repair order violation errors, because it is difficult to identify them at the development phase. Previous work, called Repairing Atomicity Violations (Repairing-AV) diagnoses order violations for each access event by comparing execution order of accesses. As a result, Repairing-AV has time overhead that is proportional to the number of access events to shared variable. This paper presents a tool called On-the-fly Repairing System (ORS) that can repair order violations of object methods containing access events. The ORS diagnoses order violations by using correct order of object methods, and treats them by stalling its thread where the error is about to occur. Experimentation with five synthetic programs shows that ORS is more efficient than Repairing-AV when the number of access events is greater than sixty.

  • Based on the findings of a study focused on medical institutions(Fama & French, 2002), this study determined possible causality between determinants of capital structure and liability level, while estimating targeted debt ratio. Moreover, it also examined hypotheses about the adjustment of targeted debt ratio and the of fundraising patterns, so that it verified the relative priority of trade-off theory and pecking order theory. First, profitability had positive(+) relationships with liability level, while investment opportunities had negative(-) relationships with liability level. This finding supported pecking order theory, and non-liability tax shield effects had negative(-) relationships with liability level as estimated in both trade-off theory and pecking order theory. Next, this study verified trade-off and pecking order theory at once by means of regression analysis about the variation of liability level in associations with disparity from targeted debt ratio and short-term fluctuation of profit and investment. As a result, it was noted that liability level became mean-reversed to targeted liability ratio but slowly, SO it was difficult to assert that such mean reverse may support trade-off theory. However, the finding that most of short-term fluctuations of profit and investment are absorbed into liabilities supported pecking order theory. On the other hand, it was found that the larger scale of medical institutions is more supportive of pecking order theory in the associations between liability level and profitability and the fundraising patterns than trade-off theory.
