This paper proposes a new class of distribution using the concept of exponentiated of distribution function that provides a more flexible model to the baseline model. It also proposes a new lifetime distribution with different types of hazard rates such as decreasing, increasing and bathtub. After studying some basic statistical properties and parameter estimation procedure in case of complete sample observation, we have studied point and interval estimation procedures in presence of type-II censored samples under a classical as well as Bayesian paradigm. In the Bayesian paradigm, we considered a Gibbs sampler under Metropolis-Hasting for estimation under two different loss functions. After simulation studies, three different real datasets having various nature are considered for showing the suitability of the proposed model.

The purpose of this paper is to clarify the actual conditions of entrepreneurial school which was drawn from the new industry-academy cooperation paradigm, and to suggest a role model for educational program for entrepreneurial school, in order to increase its self-generating ability. According to survey of 5 entrepreneurial schools, most of curriculums did not show a user-based. This indicates that series of processes, such as analyzing user's(learner, local community, institution) request and setting up the goal are not being conducted professionally and systematically. Through this study, I would like to deliver the importance of new industry-academy cooperation paradigm of entrepreneurial schools and incite them to apply major principles of new industry-academy cooperation paradigm to their entrepreneurial education program, in order to enable continuous survival and development. This study has conducted research on the actual conditions of entrepreneurial school to examine whether the role model of entrepreneurial education program coincides with the paradigm of new industry-academy cooperation paradigm. Thus, this study has conducted two verifications as whole. First, through theoretical examination, this study has drawn out the major principles of new industry-academy cooperation paradigm and considered effective applying method for it. Second, this study has analyzed overseas' cases for development of entrepreneurial education program and proved the propriety of major principles. Through theory and case studies, the study presented a role models for each subjects and provided necessity for applying major principles to entrepreneurial school's research on the actual operating condition.

In the West, the model for provision of services to the disabled has shifted from a focus on the individual to that of a social model. This shift reflects a movement away from a materialist approach to one that is grounded in idealism. In the context of themultiple service paradigm movement this paper explores trends in the provision of social services to the disabled in Korea. In order to accomplish this task the writer conducted an analysis of Korean Community Chest proposals, existing legislation and legislative systems as well as the disability movement in Korea. Data was collected from the 2003 program proposals submitted to the Korea Community Chest. This data was classified using Priestly's Multiple Service Paradigm of Disability. The results suggest that the Korean Community Chest favored an individual idealist approach. There was only limited support given to proposals that reflect the social model approach and thus issues of accessibility, independent living and inclusion are given short shrift. This paper argues the need for a reversal of this trend through the Korean Community Chest supporting issues mentioned above and that the social model should be given greater attention by this funding body. Implications for practice using the multiple paradigm model are discussed.

In this study, based on the principal-agent paradigm, we investigate a joint cost reduction activity in a buyer-supplier supply chain where a buyer motivates its operations department and a supplier to reduce the supply chain's production cost. We construct a benefit-sharing model based on the target cost scheme, a basic philosophy in practice which has not been explored in previous studies. The model also incorporates various supply chain issues such as the cooperation of multiple agents, the opportunity loss, and the degree of strategic relationship between the buyer and the supplier. Based on the analysis of the principal-agent model, we investigate the benefit-sharing rule to control agents' actions, and we also provide important managerial implications into supply chain practices via extensive comparative static analyses.

The methodology for maintenance system development should overall be considered with all of task characteristic, schedule, and the technical condition of investment sources. This research applies Waterfall model to methodology for the development and construction of maintenance system through customizing the CD (Custom Development) procedure of "HSDM (Hyundai System Development Methodology)" based on information engineering. The waterfall model called as classic life cycle paradigm is defined for the sequent development procedure, which make progress a next step after that a previous step is admitted with thorough review. This model which is popular and the oldest paradigm is used for system development by four steps; demands analysis, design, construction, and maintenance. This methodology advances higher abstract step from higher lower step using top-down approach from concept definition to construction, which notices the end of a step whenever a step is over. Therefore, each step is exactly divided, and consequently the output is clearly yielded.

The primary goal of virtual prototyping is to eliminate the need for fabricating physical prototypes, and to reduce cost and time for developing new products. A virtual prototyping seeks to create a virtual environment where the development of a new model can be flexible as well as rapid, and experiments can be carried out effectively concerning kinematics, dynamics, and control aspects of the model. This paper addresses the virtual environment used for virtual prototyping of a passenger vehicle. It has been developed using the dVISE environment that provides such useful features as actions, events, sounds, and light features. A vehicle model including features, and behaviors is constructed by employing an object-oriented paradigm and contains detailed information about a real-size vehicle. The human model is also implemented not only for visual and reach evaluations of the developed vehicle model, but also for behavioral visualization during a crash test. For the real time driving simulation, a neural network model is incorporated into the virtual environment. The cases of passing bumps with a vehicle are discussed in order to demonstrate the applicability of a set of developed models.

The purpose of the study is to design a space-based locality documentation model. It begins with analysing the changes of directions and strategies of locality documentation through literature surveys. Based on the analysis, a new paradigm of locality documentation is suggested in digital environment. It then suggests space-based documentation model, i.e., 'spanDoc Model (SPAace-based Networked Documentation Model)' which represent the new paradigm. The model focuses on planning the framework of use and accumulation of locality documentation.

At present, electric power industry around the world are being gradually changed to a new paradigm, such as electrical energy storage system, the wireless power transmission. Demand for ESS, the core technology of the new paradigm, has been growing worldwide. However, it is essential to estimate the optimal capacity of ESS facilities for frequency regulation because the benefit would be saturated in accordance with the investment moment and the increase of total invested capacity of ESS facilities. Hence, in this paper, the annual optimal mathematical investment model is proposed to estimate the optimal capacity and to establish investment plan of ESS facility for frequency regulation. The optimal mathematical investment model is newly established for each season, because the construction period is short and the operation effect for the load by seasons is different unlike previous the mathematical investment model. Additionally, the marginal operating cost is found by new mathematical operation model considering no-load cost and start-up cost as step functions improving the previous mathematical operation model. ESS optimal capacity is established by use value in use iterative methods. In this case, ESS facilities cost is used in terms of the value of the beginning of the year.

The e-Government in Korea has made such good results as improvement of official work productivity and citizen service quality. However, e-Government in Korea involves many problems and subjects to must solve, especially, at the side of citizen services. Every public organization as supplier provides each service of themselves to the civilians. Citizens feel inconvenience yet, because they must visit and are supplied various civil services to one public affair from several public institutions. When we consider the paradigm shift of the e-Government service, the status and problems of the e-Government in Korea required more better service model to the citizen. To realize the citizen oriented service, the integration and linkage of the system infrastructure and applications among governmental organizations are required. In this changed situation, when new one/non-stop service model of the digital government is developed and launched, the e-Government can supply better service to the citizens. In this study, the model that we suggest is among the new service models of the e-Government, named the Integrated Civil Service Model. The e-Government involving the Integrated Civil Service Model can make more outcome, such as better civil life convenience, cost-effective results by processing time and cost reduction for public affairs of citizens.
