Purpose: The purpose of this study was to explore the experience of fluid management in hemodialysis patients by describing how they manage fluid intake and what affects fluid management. Methods: Purposive sampling yielded 11 patients who have received hemodialysis for one year or longer in one general hospital. Data were collected through in-depth interviews and analysed using Giorgi's phenomenological method. Data collection and analysis were performed concurrently. Results: The findings regarding how hemodialysis patients manage fluid intake were classified into four constituents: 'recognizing the need for fluid control', 'observing the status of fluid accumulation', 'controlling fluid intake and output', 'getting used to fluid management'. The factors that affect fluid management of hemodialysis patients were revealed as 'willpower', 'change in the mindset', 'support system', and 'emotional state'. Conclusion: The study results show that hemodialysis patients manage fluid intake through food and exercise as well as interpersonal relationships. These findings suggest that strategies in the development of nursing interventions for hemodialysis patients should be directed at assisting them in familiarization with fluid management based on an understanding of their sociocultural contexts.

In this paper, a new design method for Assembly Line Control System(ALCS) is presented. This system consists of five independent modules having their own specific functions such as production management, facility management material management, quality management, and remote control. To implement the ALCS, we propose design of the common data management module(CDMM). This module has the roles of integrating the above five modules and of communicating the common data between them. Using this method, we realize an information management method in the view of CIM. In addition, we standardize the inter-communication of common data between machines having different interface protocols.

Purpose: This study was to identify nursing diagnosis-outcome-intervention (NANDA- NOC-NIC: NNN) linkages applied to inpatients in general surgical nursing units. Methods: We developed the NNN linkage computerized nursing process program, which consisted of the 107 nursing outcomes and the 190 nursing interventions linked to the 39 nursing diagnoses. This program was applied to 324 patients who admitted to those nursing units from July, 2004 to February, 2005. Results: First, nursing outcomes of each nursing diagnosis were identified as follows: for 'acute pain', pain control, pain level, and comfort level; for 'risk for infection', wound healing: primary intention, wound healing: secondary intention, and infection status; for 'nausea', nutritional status: food & fluid intake, comfort level, symptom severity and hydration. Second, major nursing interventions for each nursing outcome were analyzed as follows: for pain control or comfort level, pain management and medication management; for pain level, pain management and analgesic administration; for wound healing: primary intention, incision site care and wound care; for Wound healing: secondary intention or infection status, infection control; for nutritional status: food & fluid intake, fluid monitoring; for comfort level, nausea management; for symptom severity, nausea management and vomiting management; for hydration, fluid/electrolyte management. Conclusion: This identified NNN linkages will facilitate the use of nursing process in surgical nursing practice and documentation systems.

In this paper, we propose a new approach to solve stochastic fluid flow models applied to the analysis of ceil loss of an ATM multiplexer. Existing stochastic fluid flow models have been analyzed by using linear differential equations. In case of large state space, however. analyzing stochastic fluid flow model without numerical errors is not easy. To avoid this numerical errors and to analyze stochastic fluid flow model with large state space. we develope a new computational algorithm. Instead of solving differential equations directly, this approach uses iterative and numerical method without calculating eigenvalues. eigenvectors and boundary coefficients. As a result, approximate solutions and upper and lower bounds are obtained. This approach can be applied to stochastic fluid flow model having general Markov chain structure as well as to the superposition of heterogeneous ON-OFF sources it can be extended to Markov process having non-exponential sojourn times.

Nowadays the importance of equipment reliability and efficiency is increasing and the concept of Total Fluid Management is introduced to make production cost down and improve equipment reliability. In this paper, basic survey on the current status of lubricants application and equipment maintenance is made. Lubrication point of the factory was 233 and 60 percent of the point was lubricated by hydraulic oils. Lubricants used at 87 points were different from those of original equipment manufacturers' recommendation. And 40 percent of the points are heavily contaminated. Exchange of oils, use of filter, computerization and so on were recommended. And introduction of Total Fluid Management concept is required.

Chest lateral decubitus is a chest examination to determine the persence of pleural fluid in thorax. In this study, we prepare recumbent holding position time standard of chest lateral decubitus. The records of 15 patients with chest lateral decubitus between May and Jun. Recumbent holding time is 30, 60, 90, 120, 180, 210, 240 seconds. The result is fluid level change between 0.88mm to 9.63. Fluid heigh change between 9.9 percent to 42.5 percent. We can confirm fluid level change with chest decubitus image. The proper time for fluid level change is 180 seconds.

It is indispensable to modern society metal processing since the industrialized rapidly, but it is a metalworking cutting fluid immediately. In addition, this means selecting a emulsion on the basis of quality criteria processing method, the material of the material, cutting depth, cutting speed, Djourou fence Liang, and surface roughness, cutting oil, the shape of the device based on the emulsion, I will be the structure of the tank, filtration equipment also changes. In particular, acting bacteria is now breeding in response to the passage of time due to metal ion degradation due to heat generated hydraulic fluid leakage, humidity tung, during processing, seep from processing material at the time of processing the water-soluble cutting oil for generating the malodor by dropping significantly the performance of the cutting oil to corruption from, sometimes by introducing various additives to suppress spoilage in advance. In this study, we expect the effect of the cost reduction in the extension of fluid replacement cycle through the application of the management apparatus and deep understanding in the management of cutting fluid, the working environment through the understanding and interest of workers in the production site more than anything I try to become useful for the improvement.

Objectives : Recently the case of lactobacillus mixture culture fluid appliment was reported. In this study, anti-inflamation effects and anti-allergy effects were studied by stimulus of lactobacillus mixture culture fluid extracts in HaCaT cells. Methods : The atopic dermatitis were induced by TNF-${\alpha}$ and interferon-${\gamma}$ in HaCaT cells. TARC/CCL17, MDC/CCL22, RANTES/CCL5 and ROS production were investigated to explain anti-inflamation and allergy effects of lactobacillus mixture culture fluid with cell-enzyme-linked Immunosorbent assay in 450 nm, 485 nm, 535 nm with spectro-fluorometer. Results : The extracts of lactobacillus mixture culture fluid were decreased TARC/CCL17, MDC/CCL22, RANTES/CCL5 expressions and ROS production with a concentration dependent manner. Conclusions : The effects mechanism of Lactobacillus mixed culture fluid for atopic dermatitis symptoms were considered to be explain anti-inflamation and allergy effects via control of cytokine, chemokine and ROS production, and the fluid could be applied in skin cells directly. But classified AD symptom degrees reported in clinical case before as Reaction Period, Reduction Period, Effect Period, Reproduction Period and Rebound Period could not be explained. Further study will be expected.
