Purpose: The purpose of the study was to evaluate the accuracy of two different fluid intake measurement methods (fluid only vs. all dietary intake) in measuring fluid balance compared to body weight change among patients with cancers. Methods: A total of 60 cancer patients in an urban cancer center in South Korea participated in the study. Adult patients who were over 18 years old; having 24-hour I&O order; and taking either normal regular diet or soft blend diet were included. Demographic information and disease related information were also gathered. The data were analyzed using SPSS 18.0 program. Results: Measuring 'fluid only' for oral intake was a more accurate measure than measuring 'all dietary intake' (p=.026 vs. p=.094). Both methods had positive correlations with the amount of weight change (r=.329, p=.010; r=.303, p=.019). Measuring body weight was a more accurate and efficient way of evaluating the fluid balance than 24 hour cumulative I&O. Conclusion: Developing clinical manual for selecting proper patients who needs fluid balance monitoring is imperative. Administering weight check and/or 24 hour cumulative I&O should be considered thoroughly based on solid nursing evidence in future.

In this paper, a new method for colour measuring is presented using fuzzy modeling technique. The fuzzy and polynomial inferences are used for obtaining RGB characteristic curve. The eight RGB real data from expert dye-stuff manufacturer, are simulated. The results show that the proposed method will is more excellent than other methods, in the colour measuring process of textile field.

The purpose of this study was to offer the basis contributes to extract the standardized body data from 3D body measuring for women aged 60 and older. The WB4 of Cyberware was used, and the measuring program of 3D scanning data was 3DM. This study was focused to verify the reliability of 3D data and to offer the effective utilization of 3D measuring on the research for elderly women■s body. Subjects were 19 women aged 60 and older. And three women in late twenties and three dressforms for women were comparing subjects to analyze the signiscant difference by age or human body variable making error. First, 3D scanning was executed twice on each subject, but any significant difference was not appear between two scanning data. So we certifed we could get the consistent and reliable data from the 3D scanner used in this study. Second, the reliability of 3D measuring data was analyzed, and the error range which meant the difference between 3D data and traditional measuring data was analyzed. In elderly women, the significant difference between two data was appeared in 19 body parts. The 7 of 19 were concerned with armpit point. In young women, three significant difference were appeared, and in dressforms, any significant difference was not certified. From these results, we could certify that age or human body variable produced the difference between two data. Third, the data of elderly women from three measuring methods, 3D measuring, traditional measuring, and measuring on 2D photographs were compared. From the result, we found that the 3D measuring data was quite reliable for most body parts excluding some width parts. But in elderly women, there were some limitation to extract reliable data because of their unique body characteristics. In order to be a role of the effective measuring method, the 3D measuring protocol reflected the body characteristics of each age or gender had to be prepared.

Scattering of surface materials has been known as one of the most important aspects in evaluating the acoustics of concert halls are designed. One of the methods that can reduce the errors in estimating the reverberation time and other acoustic parameters through computer modeling is to calculate scattering coefficient of surface materials. However. so far, no objective and reliable methods measuring scattering coefficient has been suggested. In this situation, ISO has suggested the method of measuring the random-incidence scattering coefficient on surfaces in diffuse field, whereas AES has introduced a method on directional-incidence in free field. In this study, the scattering coefficients of five kinds of hemispheres (1.5, 2.0. 2.5. 3.0. 3.5cm) were measured by using the ISO method in 1：10 reverberation chamber. It was found that 3.0cm hemisphere has the highest scattering coefficient satisfying 95％ reliability.

Efforts have been devoted to developing rapid and accurate methods for measuring the errors of machine tools. The method os measurement and calibration of machine tool errors should be general and efficient. The objective of this study is to show in detail the full sequence from the measurement of errors factors to the verification of the positioning accuracy after compensation for the volumetric error. In this paper, we described the steps in measuring the volumetric error parameters, a general error model composed of error parameters, temperature, and the desired position. The validity of the error calibration methods proposed in this paper was tested using a vertical 3-axis CNC machine with a laser interferometer and a ball bar.

Though conventional calorimetry methods such as differential scanning calorimetry (DSC) and differential thermal analysis (DTA) are used generally in measuring heat of fusion, T-history method has the advantages of a simple experimental apparatus and no requirements of sampling process, which is particularly useful for measuring thermal properties of inhomogeneous phase change materials (PCMs) in sealed tubes. However, random criteria (a degree of supercooling) used in selecting the range of latent heat release and neglecting sensible heat during the phase change process can cause significant errors in determining the heat of fusion. In the present study, it was shown that a 40% discrepancy exists between the original T-history and the present methods when analyzing the same experimental data. As a result, a reasonable modification to the original T-history method is proposed.

Size distribution of diesel particles measured by ELPI and SMPS were compared. The results of ELPI and SMPS showed acceptable agreements in the qualitative comparison but showed differences in the quantitative comparison. In addition, the results of ELPI and SMPS showed a same trend about the change of engine loads. In this study, the effects of dilution methods and measuring positions on the measurement of PM size distribution were also studied by using the SMPS. As results, the decrease of large particles and the increase of small particles were observed when the dilution air was heated. It was also observed that the number concentration of the diesel particles was varied within 20$\%$ by the different measuring positions of 140 cm.
