Intranet emerges as a key technology for building enterprise information system. This paper proposes a scenario-based object- oriented technique for designing intranet hypermedia information systems. The method consists of six phases such as domain analysis, object modeling, view design, navigational design, implementation design and construction. Users requirements are analyzed in the form of scenarios by the use fo a responsibility-driven object technology. Object-oriented views are generated from the resulting object model and then used for the subsequent navigational and implementation design. Implementation design phase deals integrating enterprise databases with distributed hypermedia systems by employing Java language. To demonstrate its usefulness, a real-life bank case is illustrated.

A statistical downscaling methodology has been developed to investigate future daily wind speeds over South Korea. This methodology includes calibration of the statistical downscaling model by using large-scale atmospheric variables encompassing NCEP/NCAR reanalysis data, validation of the model for the calibration period, and estimation of the future wind speed based on the general circulation model (GCM) outputs of scenario A1B of the CGCM3. Based on the scenario A1B of the CGCM3 model, the potential impacts of climate change on the daily surface wind speed is relatively small (+/- 1m/s) in South Korea.

The development of advanced nuclear fuel cycle(ANFC) technology is essential to meet the national mission for energy independence via a nuclear option in Korea. The action target is to develop environmentally friendly, cost-effective measures to reduce the burden of long term disposal. The proper scenarios regarding potential radionuclide release from a repository have been developed in this study based on the advanced korean Reference Disposal System(A-KRS). To predict safety for the various scenarios, a new assessment code based on the GoldSim software has also been developed. Deterministic analysis indicates an environmental benefit from the ANFC as long as the solid waster from the ANFC act as a proper barrier.

There is a need to analyze various factors in evacuation safety assessment of building in fire. In the current performance based design, evacuation safety assessment in case of fire is being conducted through the simulation as FDS and Pathfinder. However, the location and size of the door, the location of evacuation in the event of a fire are not considered when design. Accordingly, it is difficult to determine the worst case scenario considering the actual fire. Therefore in this study, in this study, we will propose an appropriate evaluation plan through simulation considering the worst-case scenario that may occur in case of fire.

With the popularization of mobile devices, the number of social network service users is increasing, thereby the amount of data is also increasing accordingly. As Internet of Things environment is expanding to connect things and people, there is information much more than before. In such an environment, it becomes very important to recommend the necessary information to the user. In this paper, we propose a recommendation method that considers new users in IoT environment. In the proposed method, we recommend the information by applying the centrality-based social network analysis method to the recommendation method using the social relationships in the social IoT. We describe the seven-step recommendation method and apply them to the music circle scenario of the IoT environment. Through the music circle scenario, we show that we can recommend more suitable information to new users in the IoT environment than the existing recommendation method.

The evaluation systems in SHS(Ship Handling Simulator) or ERS(Engine Room Simulator) give trainees the opportunity to feedback how they responded suggesting them the operation result by scores. If SHS and ERS are integrated each other by network to enable the synchronous training for both deck and engine officers these systems need to include inherently the function of integrated evaluation which produces the evaluation score for the team play of deck and engine officers. The integrated evaluation is effective especially when assessing the responses at emergency situation of ship or the matter of efficiency of ship operation even if assessors feel difficult in editing simulation scenarios for integrated evaluation. This study focuses on the property of integrated evaluation and considerations when editing them. It suggests also a useful procedure to estimate whether a scenario for integrated evaluation is reasonable and balanced or not based on the analysis in the proprieties and reasonabilities which are to be prepared by assessors before testing trainees or examinees.

This study aims to establish a methodology for rational fire risk assessment for building evacuation safety in case of fire, and specifically, to propose a fire risk assessment technique using fire scenarios considering various uncertain factors in case of fire. In order to analyze the extent to which the assumed conditions can occur, that is, the probability of each accident caused by fire, the safety rate is analyzed according to the presence or absence of each factor by using fire statistics. Factors related to the fire protection performance and evacuation ability of buildings are defined as disaster factors. In this study, disaster factors were classified into the following three categories.

For a successful performance of Carbon Capture Sequestration (CCS) projects, appropriate injection conditions should be designed to be optimized for site specific geological conditions. In this study, we built a simple 2-dimensional analysis model, based on the geology of Jang-gi basin which is one of the potential sites of domestic CCS projects. We evaluated the impact of initial stress conditions and injection rate through coupled TOUGH-FLAC simulator. From the preliminary analysis, we constructed risk scenarios with the higher potential of shear slip and performed scenario analysis. Our analysis showed that normal stress regime produced the highest potential of shear slip and stepwise increasing injection rate scenario resulted in much larger pore pressure build up and consequent higher potential of the shear slip, which was evaluated using a mobilized friction coefficient.

Market segmentation helps providers to find better marketing opportunities and allows foodservice managers to develop the right product for each target market. Therefore, this study, taking university faculty and staff as subject, is intended to diagnose the relative value of service quality attribute, on the basis service quality scenario of faculty foodservice; to suggest price for improving customer loyalty in market segments. A questionnaire was developed ar d mailed to 600 Yonsei university faculty and staffs. A total of 385 questionnaires were usable; resulting in a 58.7％ of faculty and a 69.7％ of staff response rate, respectively. Statistical data analysis was completed using the SAS/Win 6.12 for descriptive Analysis, ANOVA, principal factor analysis, cluster analysis, reliability test and discriminant analysis. The results of the study are as below. Eighteen questions were selected for measuring respondents' lifestyle by AIO method and the seven lifestyle factors derived from factor analysis and aggregated distinct 4 clusters. Service quality attributes of the scenario were determined with 'food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation'. 'Food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation', in decreasing order, were identified as improving customer loyalty. However, most faculty and staffs were satisfied with the present meal price. The result of this study indicates that the relative value of service quality was differed significantly among the various market segments. 'Food quality', 'menu variety', and 'atmosphere' were determined as major service quality attributes. Thus, customer loyalty could be increased by improving food taste and quality, atmosphere, and service delivery. (Korean J Community Nutrition 8(4) : 556 ∼565, 2003)
