This paper presents a decision making model for the cruise ship management. A network based optimization model has been developed for a single cruise ship operation. It gives optimal itinerary patterns over the planning period for the cruise ship managers wanting to maximize profit from the cruise ship operation. A network solution method to find the optimal solution is also developed. This network model can be equivalently transformed into a linear programming model, which makes the implementation of the model quite practical however complicated the given set of possible itineraries may be. The ship scheduling network developed in this study can also be used as a general framework to describe all possible cruise ship itineraries the cruise ship manager can figure out.

The purpose of this study was to test a causal model of employed and unemployed wives on the basis of the family resource management system theory. The data of this study were obtained from 244 wives who lived in Seoul and were financial mangers. Major findings of this study were as follows: 1. Both employed and unemployed wives, knowledge of financial management was significantly predictor of financial planning. That is, household financial mangers with more financial knowlege used more effective planning behaviors than did those financial managers with less financial konwlege. This results emphasize the significance of enhancing the financial konwledge in the household financial management. 2. For unemployed wives, expectation of household’s future financial condition was influenced by age, household income, locus of control over their financial situation, and perception of financial management’s effectiveness. The strongest predictor of expectation of the household’s future financial situation was age. Younger managers were more optimistic about the future. 3. The findings of this study support theoretical framework on the basis of the family resource management system theory, both for employed and unemployed wives.

Recently, high-rise building projects have been in the spotlight in South Korea. Curtain wall construction, as one of important operations in the high-rise building projects is composed of various, entangled and complex unit processes that require a systematic planning to prevent unexpected delays. A schedule simulation technique has been used for deriving more efficient planning and accurate performance measurement. However, the simulation technique has difficulty in collecting actual data and in applying data fluctuations during construction. Thus, this paper suggests a concept model of Modular Simulation Model(MSM) that overcomes such limitations of traditional simulation technique based on curtain wall operations.

The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based on the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

This study examines a normative model of project management systems, PPMS, to provide information for directing R&D activity in order to increase R&D productivity. The PPMS (Project Process Management System) is a disciplined and systematic framework to manage R&D projects effectively and efficiently under the assumption of a strategic decision making and long-range planning. The purpose of PPMS is to provide for the management of research organization at different levels an effective management tool; first, for the planning system which deals with rational selection and authorization of R&D projects, second, for the control system which concerns monitoring and controlling the execution of R&D projects, and finally, for the evaluation system which attains evaluation of the performance results of R&D projects and determination of the necessary follow-up. A view for the future development of project management within the context of a project-performing organization is also elaborated to exhibit the progress and phase description of the project management system.

This paper presents a competency-based system for supporting corporate strategic information system planning. This system is implemented in practice via a detailed three stage methodology. The three stages are defining current business, analyzing competency, and suggesting To-Be enablers. The business objectives are evaluated on competencies in terms of experts' preference information about degree of importance between competencies on them. This system provides an efficient, systematic and structured framework and helps dramatically reduce the time needed to plan strategic information system.

In recent years, motivated by the emergence of ubiquitous computing technologies, a new class of networked robots, ubiquitous robots, has been introduced. The Ubiquitous Robotic Companion (URC) is our conceptual vision of ubiquitous service robots that provide users with the services they need, anytime and anywhere in ubiquitous computing environments. To realize the vision of URC, one of the essential requirements for robotic systems is to support ubiquity of services: that is, a robot service must be always available even though there are changes in the service environments. Specifically robotic systems need to be automatically interoperable with sensors and devices in current service environments, rather than statically preprogrammed for them. In this paper, the design and implementation of a semantic-based ubiquitous robotic space (SemanticURS) is presented. SemanticURS enables automated integration of networked robots into ubiquitous computing environments exploiting Semantic Web Services and AI-based planning technologies.

The objective of this study is to interpret a typical Korean traditional settlement for searching for planning criteria of ecological friendly housing estates. The interpreting framework is five environmental ecological ideas as the adaptation to the exterior of village, the eco-space in village, the interior of house, the cycling of material and the reasonable energy system, prevention of environment pollution and reduction of wastes. Through the interpretation, it has been found out that Bang chon village has been developed to an environmental ecological rational setting and has the meaningful elements for environmental friendly housing estates. Particularly, the spatial components of Bang-chon are characterized by the concept of multi-function, and diversity, which are worth of being considered as important planning of ecological friendly housing estates.

The purpose of this study Is to develop water quality management system fort a farm village stream. The framework design of the system and the ecological monitoring of a test watershed were carried out, The system consists of GIS(Geographic Information System ), database, pollution source management, water quality and hydrologic analysis. Suri watershed located on Idong, Yongin city, Kyunggi Province, was selected as the test watershed for the application of the system. The fifteen's monitoring stations were chooses at up- and down-stream of the watershed. The results of an aquatic ecological monitoring were analyzed by the GPI(Group Pollution Index) method. The GPI revealed that water quality was varied within the stream. GPI and DO map for the watershed stream were developed, These maps facilitated to analyze the spatial distribution of the water quality.

Currently, many companies are trying to be more competitive by implementing the most appropriate software package, called ERP (Enterprise Resource Planning). ERP can support the company's business process. A repository, which can store and retrieve enterprise-wide information, is a key component of such software package. This paper implements an enterprise repository for the ERP. A well-known repository standard, IRDS (Information Resource Dictionary System), is employed for the repository architecture. The proposed metadata schema can help develop database, business applications, models, and workflow. To illustrate the practical usefulness, a real-life ERP prototype is built within the framework of the proposed repository.
