The major goal of caring the elderly is not to cure the patient, but rather to improve or maintain the individual functional ability. With the aged population increases, there is increasing consensus among health care workers about the importance of developing a tool to measure and evaluate the health status of the elderly. As many writers is pointing out, care of the elderly embraces the spectrum of physical-social-psychological problems and an enormous number of variables could be introudeced into the health worker's routine measurement. But such an expansive approach to measurement could have disadvantages. The purpose of this study is to introduce the measurement tools of physical functioning, perhaps the most important measure required in long-term care, which are separated into three categories of measures; general physical health, ADL, IADL. It is important that all health workers who provide care to the elderly incorporate the concepts of functional health status into the routine assessments. And continuous study about reliability and validity is needed to apply those foreign tools to Korea.

Currently, many researches are carried out about tilting index table, which is one of the main component of 5-axis machine tool. The performance of the tilting index table is associated the rotational accuracy which is very important factor for high precision machining because it have an effect on machining error. In this paper, a tilting index table is developed, and the rotational accuracy of the tilting index table using a laser measurement equipment is measured. In addition, a correction value is obtained from the measured value through compensation, and the correction value is used to improve the accuracy of the table. Comparative analysis is carried out for the accuracy of the table before and after compensation. This paper can be used by a reference for performance and reliability advancement of tilting index table.

Purpose: The aim of this study was to assess the Turkish adaptation of the COVID Stress Scale (CSS) on the basis of determining the stress caused by the coronavirus disease (COVID-19) pandemic, and to test its validity and reliability. Methods: The English CSS was translated into Turkish using forward and backward translation. Data were collected online from 360 participants. Construct validity was evaluated using confirmatory factor analysis, exploratory factor analysis, and content validity. Pearson product-moment correlation, Cronbach's alpha reliability coefficient, and test-retest methods were used to evaluate reliability. Results: The Turkish version of the CSS has 36 items consistent with the original scale and has five factors: COVID danger and contamination, socioeconomic consequences of COVID, COVID xenophobia, traumatic stress due to COVID, and compulsive checking for COVID. The construct validity of the Turkish version of the CSS was verified by the adjusted goodness of fit index > .85, and comparative fit index > .95. The content validity index of each item was 91%. The corrected item-total correlations of the scale ranged from .51 to .89. Internal consistency was reliable, with a Cronbach's α of .93. Conclusion: The Turkish version of the CSS is valid and reliable. It can be used as a measurement tool for the assessment of COVID-related stress.

Purpose: The purpose of this study was to examine the reliability and validity of a Korean version of the Critical Care Pain Observation Tool (CPOT) developed for assessment of pain in critically ill nonverbal patients. Methods: Data were collected from a convenience sample of 30 critically ill patients admitted to a medical ICU in a hospital. The CPOT was tested at before, during and 20 minutes after changing a position and suction. Upon establishment of content and translation equivalence between the English and Korean version of CPOT. Results: The interrater reliability was found to be acceptable with the kappa coefficients of .76-1. The construct validity of the pain scores were increased from 0.43 to 2.5 in changing a position (t=-8.60, p<.001)and 0.1 to 3.23 (t=-9.36, p<.001) in suctioning. The pain scores were decreased from 6.06 to 4.01 in changing a position (t=-10.19, p<.001) and 6.45 to 4.13 (t=-10.39, p<.001) in suctioning. The concurrent validity the correlations between pain scores and physiological indicators, and a increased in Heart rate before and after changing a position (r=.65, p<.001). Conclusion: The CPOT can be used as a reliable and valid measure to assess pain in critically ill nonverbal a medical ICU patients.

The objective of this study is to evaluate the reliability of DEA for the measurement of efficiency of Commercial banks in Korea using the DEA methods. DEA is basically a mathematical programing technique initially developed by Chanes, Cooper and Rhodes(197n) to evaluate the relative efficiency of not-for-profit organizations where multiple outputs are produced with multiple inputs. This study show that DEA approach is not only usefulness in evaluating performance of banks but also a useful bank management tool.

This study investigated technological and managerial barriers in technology startups through a survey of 151 companies, yielding 118 responses (78.1% response rate). Factor and multivariate analyses identified two distinct barriers: technological and managerial. Reliability analysis validated the measurement tool. Using MANCOVA, 12 hypotheses were tested, incorporating six independent variables. Results revealed significant disparities in technological and managerial barriers based on establishment type, commercialization goals, growth stage, and commercialization stage, with 5 hypotheses supported. This study highlights the crucial role of these variables in understanding barriers within technology-based startups.

이 연구의 목적은 래스터입체사진술이 적용된 ABW-mapper를 사용하여 얻은 관상면 상에서의 하지 정렬 측정에 대하여 측정자 내, 측정자 간, 측정-재측정 간 각각의 신뢰도와 타당도를 조사하고 평가하는 것이다. 열여덟 명의 대상자가 이 연구에 참여하였다. 일주일간격으로 두 번의 세션에 걸쳐서 두 사람의 측정자가 각각 ABW-mapper를 사용하여 기립자세에서의 S각(입체사진 각-래스터입체사진 촬영을 통해 측정한 관상면상의 하지 정렬 측정 각)을 측정하였고, 첫 번째 세션에서는 짧은 시간 간격으로 한 측정자가 같은 대상자에 대하여 두 번씩 측정하였다. Q각은 디지털카메라로 기립자세를 촬영한 사진에서 고니어미터로 측정하였다. HKA각은 컴퓨터 기반 디지털 방사선 영상사진 위에서 측정 소프트웨어를 사용하여 측정하였다. 급내상관계수(ICC)를 통해 신뢰도를 분석하였고, 피어슨 상관계수를 사용하여 타당도를 검사하였다. 그 결과, S각 측정은 매우 높은 측정자 내 (ICC=0.956~0.974), 측정자 간 (ICC=0.962) 검사-재검사 간 (ICC=0.945) 신뢰도를 나타냈으며, S각과 Q각, S각과 HKA각 사이에는 강한 음의 상관관계(각각 r=-0.739, -0.702)를 나타냈다. 따라서, ABW-mapper에 의한 래스터입체사진법을 통한 S각 측정은 관상면에서의 하지정렬의 측정에 대하여 Q각이나 HKA각 측정에 관련하여 예비적 또는 보완적 도구로 사용될 수 있을 것이라 생각된다.

On the machine measuring system composed of touch trigger probes, a DNC module, a CMM module, an analysis module and a man-machine interface unit was developed. Measuring accuracy is affected by working accuracy of the on the machine measuring system. The working accuracy of the system is due to geometric errors of th machine tool, servo errors of feed drives and positioning errors of probes. In order to compensate for the measuring errors due to the working accuracy, a calibration module was developed. The measuring automation system was realized with the on the machine measuring system and an IBM-PC on the machine center through a RS-232C. It turns the machining machine (CMM). The system is used for dimensional checking of machined components. initial job setup, part identification, identification of machining errors due to deflection and wear of tools. cutter run out, and calibration of machine tools. A horizontal machining center equipped with FANUC OMC wre used for verification of the system. The validity and reliability of the system. The validity and reliability of the system were confirmed through a series of experiments with gage blocks, ring gages, comparison measurement with a commercial CMM, and so on.

Good diagnostics improves both the safety and system unavailability of digital safety systems. The measure of a diagnostic capability is called the Coverage Factor. Because the Failure Modes, Effects and Diagnostic Analysis (FMEDA) provides information on the failure rates and failure mode distributions necessary to calculate a diagnostic coverage factor for a component, the FMEDA can be used as a useful tool to calculate it. Through performing FMEDA on a digital signal processor (DSP) board used in a digital safety system, it is shown that some components of the DSP board can be replaced or improved to satisfy the required diagnostic coverage. That is, the FMEDA can serve as a useful verification tool to design a diagnostic capability for the DSP board.
