  • In the existing ISP methods, the important' role of enterprise value is usually ignored or not recognized in the information systems planning (ISP). Besides, in some ISP methods, there is a connotative precondition that the main body of value is always the enterprise stakeholder. Thus, in ISP, the enterprise stakeholders‘ value has been recognized while the value of other main bodies has been neglected, which has resulted in boycott and other problems in normalization construction. Based on the existing ISP analysis frame and ways, this article analyzes the enterprise fundamental principle of enterprise value acting on ISP and defines the formation of enterprise value. On the basis of Keeney's analysis way of value focused thinking for decision-making, we induct the factors of enterprise value into the ISP method and set forth such an ISP process: (1) identify the aggregation of enterprise value; (2) conform the objective structure of enterprise levels; (3) determine the appraisal standard for enterprise fundamental objectives; (4) determine the basic structure for information systems ; (5) confirm the data requirements for information systems; (6) give appraisal and comment.

  • The purpose of this study is to evaluate the possibility of normalization of the distibutions of soil parameters taken from soft ground and the reliability of the safety factors of specific objects on it, including sanitary landfill. Through this study it is found that distributions of soil parameters could be adjusted to appropriate normal distributions as possibility density functions(PDF), and that especially the group of initial cohesions and the coresponding safety factors has a perfect linear correlation. According to those results the PDF to initial cohesion as possibility parameter can not only be tmsformed to the PDF to safety factor but also, conseqently, the reliability of the safety factor(SF) simply based on the mean value of soil parameter(Co) can be calculated or easily picked up from the standrad normal distribution table. It is therefore concluded that even though calculated values of safety factors are over any standard requirements some possibility of risk both to the objects and natural soft ground could be still existing, and also a new standard value for this slope stability control system should be derived just by adjusting old one according to the magnitude of risk possibility.

  • This study proposes a procedure for designing a labyrinth seal that meets both leakage flow rate and rotordynamic performance criteria (effective damping, amplification factor, separation margin, logarithmic decrement, and vibration amplitude). The seal is modeled using a one control volume (1CV) bulk flow approach to predict the leakage flow rate and rotordynamic coefficients. The rotating shaft is modeled with the finite element (FE) method and is assumed to be supported by two linearized bearings. Geometry, material and operating conditions of the rotating shaft, and the supporting characteristics of the bearings were fixed. A single labyrinth seal is placed at the center of the rotor, and the linearized dynamic coefficients predicted by the seal numerical model are inserted as linear springs and dampers at the seal position. Seal designs that satisfy both leakage and rotordynamic performance are searched by modifying five seal design parameters using the multi-grid method. The five design parameters include pre-swirl ratio, number of teeth, tooth pitch, tooth height and tooth tip width. In total, 12500 seal models are examined and the optimal seal design is selected. Finally, normalization was performed to select the optimal labyrinth seal designs that satisfy the system performance requirements.

  • The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

  • After the release of SDK in 2011, Kinect developed for the motion recognition games has been applied not only in game but also in various fields such as science, education, and health care. It has some problems as belated responses to player's movements, a lot of noise in the recognized data, and an untraceable player when the body is partially occluded. Because of Kinect's such peculiarities of playing environment, most Kinect games require the inconvenience of Kinect's location or player's posture correction. In this paper, we propose an interface correction method that minimizes the requirements to be asked players, manages the exceptions such as noise, and enables to process consistently the player's movements in the game using Kinect. Also, we present the delay time to be considered to develop the game using Kinect through the experiment.

  • The global community demands the reduction of environmental pollution such as greenhouse gas and carbon dioxide emissions. According to these requirements, the road construction project in the highest energy consuming industry is required the efficient way of reducing environmental pollution emissions. In this study, during the whole life cycle process, an environment impact assessment was performed for the several road construction projects in order to evaluate environmental stress through the road construction process. This study provides a proper process of environment impact assessment for life cycle assessment (LCA) analysis of road construction project, and figures the environmental stress regarding to the major construction materials for the case projects. In addition, this study conducted a sensitivity analysis for the key materials of environmental stress through the quantity analysis of major materials for the 1km section of a road construction. By this sensitivity analysis of total environmental stress change from the different volumes of constructing materials, it would be useful information for the environment impact assessment for the future road construction project.

  • Primary care takers, especially older parents, who live with and care for an adult child with mental illness struggle with the dilemma of who will provide for their child's social and emotional needs and physical care requirements when they can no longer care so. Therefore, 'Permanency plan(financial, residential, legal plan)' is very important for social integration and normalization of mental illness adults. This study aims to introduce the mental health systems in New Zealand and to investigate the permanency plan strategies(benefit, supplements, and the laws) of the government and community support services of NGOs through the interviews with team leaders of representative NGO, Te Korowai Aroha. Permanency plan strategies of New Zealand Government and NGOs are as follows. 1) Financial plans for adults with mental illness include main benefit(invalid benefit), various allowances(family allowance and disability allowance), and wage subsidies for employment. 2) The Government provide accommodation supplement and re-establishment grant for residential plan. And NGOs have supported accommodation program to provide support and accommodation that are important for social integration. 3) Adult mental illness is provided the support of welfare guardian and property manager under the Protection of Personal and Property Rights Act. According the results, this study concluded that social services for the mental illness which secure supported accommodation and benefits is strongly needed. At the same time, mental health delivery system is needed to make distinction between social services and clinical services.
