  • This descriptive-correlational study was conducted to exam if there were relation between noise level and reaction to noise of inpatient. The purpose of this study was to provide a basic data for comfort of patient hospitalized. The hypotheses of the study are : 1. The higher perceived noise level of inpatient, the higher reaction level to noise. 2. The higher perceived noise level of inpatient, physiological reaction level to noise. 3. The higher perceived noise level of inpatient, the higher emotional reaction level to noise. The participant were 153 patients hospitalized in one general hospital. The research instruments used for this study were noise scale and reaction of patient scale developed by the author. Data was collected over a period of 10 days from the 9th of July to the 18th of July, 1994. Statistical analysis of the data included percentage, t-test, ANOVA and Scheffe test. Examination of the hypotheses was done by use of pearson correlation coefficient. The results are summarized as follows ; 1. The mean score of noise level was 2.24. Among noise factors reported by the subjects, that which ranked highest was 'Conversation of Visitors'(2.82). Next were 'noise of handling receptacle'(2.73), 'the others noise from outside'(2.73) and 'Conversation of supporter'(2.71). 2. The mean score of reaction level to noise was 2.19, physiological reaction level 2.04 and emotional reaction level 2.37. Among Physiological reaction to noise reported by the subjects, that which ranked highest was 'tired'(2.39). Next were 'sweating'(2.22) and 'headache'(2.20). Among emotional reaction to noise reported by the subjects, that which ranked highest was 'to irritate nerve'(2.53). Next were 'disturbing rest'(2.51) and 'to disturb sleep'(2.46). 3. The relationship between perceived noise level of inpatient and reaction to noise was statically significant (r=0.599, p=.0001). The relationship between perceived noise level of inpatient and physiological reaction to noise was statically significant (r=0.554, p=.0001). The relationship between perceived noise level of inpatient and emotional reaction to noise was statically significant(r=0.535, p=.0001). Thus hypothese 1, 2, 3 were supported. 4. There were significant differences between noise level of inpatient, admission periods, mobility of physical condition and exposure level to noise. 5. There were significant differences between physiological reaction level to noise, admission periods, mobility of physical condition and operation Yes or No. 6. There were significant difference between emotional reaction level to noise, admission periods, mobility of physical condition and exposure level to noise.

  • This article describes an integrated Level 1-Level 2 probabilistic risk assessment (PRA) methodology to evaluate the radiological risk during postulated accident scenarios initiated during the decommissioning phase of a typical Mark I containment boiling water reactor. The fuel damage scenarios include those initiated while the reactor is permanently shut down, defueled, and the spent fuel is located into the spent fuel storage pool. This article focuses on the integrated Level 1-Level 2 PRA aspects of the analysis, from the beginning of the accident to the radiological release into the environment. The integrated Level 1-Level 2 decommissioning PRA uses event trees and fault trees that assess the accident progression until and after fuel damage. Detailed deterministic severe accident analyses are performed to support the fault tree/event tree development and to provide source term information for the various pieces of the Level 1-Level 2 model. Source terms information is collected from accidents occurring in both the reactor pressure vessel and the spent fuel pool, including simultaneous accidents. The Level 1-Level 2 PRA model evaluates the temporal and physical changes in plant conditions including consideration of major uncertainties. The goal of this article is to provide a methodology framework to perform a decommissioning Probabilistic Risk Assessment (PRA), and an application to a real case study is provided to show the use of the methodology. Results will be derived from the integrated Level 1-Level 2 decommissioning PSA event tree in terms of fuel damage frequency, large release frequency, and large early release frequency, including uncertainties.

  • The methodological framework of the Level 2 PSA appears to be currently standardized in a formalized fashion, but there have been different opinions on the way the sources of uncertainty are characterized and treated. This is primarily because the Level 2 PSA deals with complex phenomenological processes that are deterministic in nature rather than random processes, and there are no probabilistic models characterizing them clearly. As a result, the probabilistic quantification of the Level 2 PSA CET / APET is often subjected to two sources of uncertainty: (a) incomplete modeling of accident pathways or different predictions for the behavior of phenomenological events and (b) expert-to-expert variation in estimating the occurrence probability of phenomenological events. While a clear definition of the two sources of uncertainty involved in the Level 2 PSA makes it possible to treat an uncertainty in a consistent manner, careless application of these different sources of uncertainty may produce different conclusions in the decision-making process. The primary purpose of this paper is to characterize typical sources of uncertainty that would often be addressed in the Level 2 PSA and to provide a formal guidance for quantifying their impacts on the PSA Level 2 risk results. An additional purpose of this paper is to give a formal approach on how to combine random uncertainties addressed in the Level 1 PSA with subjectivistic uncertainties addressed in the Level 2 PSA.

  • According to the image level definition for KOMPSAT-2 in KOMPSAT-2 Ground Station Specification, the level 0 is frame formatted, unprocessed data at full resolution; any and all communications artifacts (e.g., synchronization frames, communications headers) removed. The level 0 is used for two purposes: 1) exchange of imagery between image receiving & processing element (IRPE), and 2) image transfer from the Receiving & Archiving Subsystem to Search & Processing Subsystem. On-board processing of imagery data of KOMPSAT-2 includes JPEG-like compression and encryption besides conventional CCSDS packetization. The encryption is used to secure imagery data from any intervention during downlink and compression allows real-time downlink of image data reducing data rate produced from the camera. While developing ground receiving system for KOMPSAT-2, it was necessarily to define level 0 products. In this paper, we will suggest level 0 product definition for KOMPSAT-2 and explain reasons of the decisions made. The key factor used while defining the level 0 products is the efficiency of whole ground receiving system. The latter half of the paper will explain the implementation of software that generates level 0 products. The necessary steps to produce level 0 products will be explained, and the performance achieved will be presented.

  • Purpose: The purpose of this study was to analyze the relation between sex perception, sexual life satisfaction, and life satisfaction of the elderly. Methods: The respondents were 227 elders aged over 65. Data were collected from February 10 to December 15, 2007 by interviews and questionnaires. Results: Of the respondents, 18.8% still had sex life and 25.5% wanted to have a date. The main reason to have a date was to relieve loneliness, and the percentage of those who wanted a date was 58.3. The perception level of sex life was 2.27 (men: 2.51, women: 2.14), the satisfaction level of sex life was 2.74 (men: 2.89, women: 2.64), and the level of life satisfaction was 2.98 (men: 3.10, women: 2.92). There was a positive correlation between the perception level of sex life and the satisfaction level of sex life; a positive correlation between the satisfaction level of sex life and the level of life satisfaction; and no correlation between the perception level of sex life and the level of life satisfaction. Conclusion: This study provides a base supporting the usefulness of various nursing intervention programs to enhance the quality of life through making elderly people have a positive perception of sex life.

  • The information sharing is essential to make collaboration by participants in the collaboration environment. The sharing of the information is necessary to reduce time-to-market of new Product. In this paper, V2-model is proposed far supporting the sharing of the information on product development. V2-model supports collaborative product development in design and supply chain. Through viewpoints, V2-model supports 1) two-level structure that consist of private level and public level ,2) level-up process and 3) product development process. The public level information supports to share the product information on collaborative supply chain and design. The viewpoints in V2-model are divided into public viewpoints that point to the public level information and private viewpoints that point to the private level information. Private viewpoints are transformed into public viewpoints. The extended Topic Map has B-Topic, S-Topic and View for representing V2-model in this paper. The level-up process of V2-model is implemented through the merging of S-Topics. V2-model is implemented with washing machine model using extended Topic Maps. In this model, the public viewpoints and private viewpoints are represented and the level-up process, which transforms private viewpoints into public viewpoints, is implemented.
