The purpose of this study was to investigate the relationships of resource financial events coping strategies and family financial satisfaction. The data were collected from 499 housewives in Seoul. The major findings: 1. The financial events were categorized into 6 factors. The factors were named as related to 'Family' 'Health' 'Money' 'Car & durables' 'Job', 'Housing'. Among these events respondents who had exprienced housing-related event reported the highest level of financial stress. 2. The coping strategies were categorized into 4 factors: 'Delaying payment' 'Borrowing' 'Economical purchasing' 'Using Worth' The most frequently used 'Economic purchasing' strategy. 3. Various coping strategies were differently used depending on financial events. For example the housewives used 'Economical purchasing' strategy to cope with family-related events and used 'Borrowing' strategy to housing-related events. Housewives who had less income and less net-worth used ' Economic purchasi g' strategy. 4. Job-related events were negatively effect to family financial satisfaction but car & durables-related event were positively effect to family financial satisfaction. Housewive who the more income and the less age had the high satisfaction. 'Delaying payment' and 'Economical purchasing' strategies were negatively related to family financial satisfaction.

This paper introduces balancing energy and memory consumption for lifetime increase of wireless sensor network. In cluster-based wireless sensor network, sensor nodes adjacent of cluster heads have a tendency to deplete their own battery energy and cluster heads occupy memory space significantly. If the nodes close to region where events occur frequently consume their energy and memory fully, network might be destroyed even though most of nodes are still alive. Therefore, it needs to balance network energy and memory with consideration of event occurrence probability so that network lifetime is increased. We show a method of balancing wireless sensor network energy and memory to organize cluster groups and elect cluster heads in terms of event occurrence probability.

Cyber-Physical system(CPS) is characterized by collaborating computational elements controlling physical entities. In CPS, human desire to acquire useful information and control devices anytime and anywhere automatically has increased the necessity of a high reliable system. However, the physical world where CPS is deployed has management complexity and maintenance cost of 'CPS', so that it is impossible to make reliable systems. Thus, this paper presents an 'Autonomic Control System towards High-reliable Cyber-Physical Systems' that comprise 8-steps including 'fault analysis', 'fault event analysis', 'fault modeling', 'fault state interpretation', 'fault strategy decision', 'fault detection', 'diagnosis&reasoning' and 'maneuver execution'. Through these activities, we fascinate to design and implement 'Autonomic control system' than before. As a proof of the approach, we used a ISR(Intelligent Service Robot) for case study. The experimental results show that it achieves to detect a fault event for autonomic control of 'CPS'.

Considerations for user-centric environments are regarded as essential for the successful deployment of convergence services in BcN. Event driven service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers to support user-centric environments. This paper first describes the deployment model and service scenario of EDS, a convergence service for user-centric environments in BcN. The user-centric environments stimulates the unified identifier management, namely unified identification (U-ID), to enable users to be provided convergence services without awareness of multiple providers. Then the designed structure and implementation results are given.

This study was conducted to investigate the effect of interview techniques on memory accuracy and suggestibility of preschool children. Forty-five preschool children participated in a magic show(target event) and 1 week later, all children received suggestive interview in two conditions(language condition & drawing condition). Another 1 week later, all children's recall contents of the magic show was assessed. During suggestive interview, children in drawing condition show more 'acception' response than children in language condition, and children in the question condition show less 'remember' response than children in drawing condition. In second interview children reported more words, and specially ones in language condition report more suggested words than ones in drawing condition. Finally, children's recalls were more accurate on controled informations of the event than on suggestive.

Low carbon construction is an important operation management goal such as cost, time, and quality in construction community. This paper introduces a system which measures the variability of carbon dioxide amounts. First, this system allows creating construction operation models of which the level of detail is breakdown into the work task level. Second, the system implements sensitivity analysis along with a ranges of resources that are allocated in an operation model. It facilitates to find the optimal resource combination using the operation performances such as the amount of emissions, operation completion time, and cost. Lastly, it identifies the best fit probability distribution functions of performance criteria given a certain resource combination. It allows project manager to query the percentages to complete the operation within a limitation specified by the system users.

Event driven service (EDS) is one of such services administrating different functions of multiple service providers according to the user situation. This paper first describes the service model of EDS, a User-centric Service for multiple service provider environments over the next generation networks. The multiple provider environments stimulates the unified identifier management, namely unified identification (U-ID), to enable users to be provided network services without awareness of multiple providers. Combining these two concepts, i.e., EDS and U-ID, the designed structure of EDS with U-ID and related procedures are given. Finally, the implementation results tested on Korea Advanced Research Network (KOREN) are described.

Purpose: The purpose of this study was to analyze the concept seogueulpeum, in order to give a operational definition of middle-aged women's seogueulpeum. Methods: Walker and Avant's methods for concept analysis was used. Results: The defining attributes of seogueulpeum identified in this study were 1) time, 2) negativity, 3) vagueness, 4) passivity, 5) individuality. The antecedents of seogueulpeum were 1) a problematic condition, 2) past event, experiences for the problematic condition, and 3) interaction between the problematic condition and past event, experiences. The consequences of seogueulpeum included 1) to get worse for the problematic condition, 2) passive or active management for the problematic condition. Conclusion: Although further studies are required to refine the diverse attributes of the concept of seogueulpeum, according to this concept analysis of seogueulpeum, this study contribute to explain psychological health of middle-aged women. In addition to develop the adequate interventions decreasing seogueulpeum with aging in women is needed.
