Purpose: This study was to examine the effects of electric stimulation therapy on chronic knee pain, exercise self-efficacy, and quality of life in Korean elderly women. Methods: The design was an unequivalent control pretest-posttest study. Samples were total of 60 (experimental: 30, control: 30) elderly women with healthy cognitive and communication abilities aged 65 years old and above. The experimental treatment involved was the electric stimulation of both thigh quadriceps muscles for 15 minutes per treatment, 3times per a week, for a total of 12 weeks. Measurements taken were S-F MPQ and AIMS for chronic knee pain, exercise self-efficacy measurement for exercise self-efficacy, and S-F 36 scale for quality of life. Data were analyzed using SPSS PC+ 12. Results: Chronic knee pain according to the Short-Form McGill Pain Questionnaire (t=43.563, p=.000) and Arthritis Impact Measurement Scale (t=31.364, p=.000) were significantly decreased in the experimental group by the application of electrical stimulation therapy. Exercise self-efficacy (t=107.116, p=.000) and quality of life (t=76.429, p=.000) were significantly increased in the experimental group by the application of electrical stimulation therapy. Conclusion: Electrical stimulation therapy could be a more effective primary nursing intervention in decreasing chronic knee pain, and on increasing exercise self-efficacy and quality of life for Korean elderly women.

Purpose: The study was attempted to provide basic materials for development of nursing-intervention programs by examining effects of growth hormone therapy on the quality of life, depression and self-esteem. Method: A survey was conducted for 31 adult outpatients as experimental group who have received growth hormone therapy more than 6 months and for 29 adults as control group who have not. A scale developed by Hilditch was used to measure their quality of life and also, the Zung's Self-rating Depression Scale and the Rosenberg's Self-esteem Scale were adopted to measure their depression and self-esteem each. Data were analyzed using one-way and two-way ANOVA Result: 1) there were differences between the two groups in the overall measurement of the quality of life. the growth hormone therapy group was higher in sub-factors 2) There were clear-cut differences between the two groups in depression, so that the control group marked higher score in the measurement of depression. 3) Self-esteem was not identical across the two groups, so that it was more higher for the growth hormone treatment group. Conclusion: Those findings suggest that development of education programs related to growth hormone and nursing-intervention is promising.

In this paper, we present a new method for monitoring of ECU's self diagnostic signals of vehicle without wire. In order to measure the ECU's self diagnostic signals, the interfaced circuit is designed to communicate ECU and a designed display terminal according to the ISO, SAE regulation of communication protocol standard. A 80C196KC processor is used for communicating ECU's self diagnostic signals and the results are sent to PDA monitoring system. Software on PDA is developed to monitor the ECU's self diagnostic signals using the Embedded Visual C++ compiler in which RS232 port is programmed by half duplex method. The algorithms for measuring the ECU's self diagnostic signals are verified to monitor ECU's state. At the same time, the information to fix the vehicle's problem can be shown on the developed PDA software. The possibility for remote measurement of ECU self diagnostic signal using PDA is also verified through the developed systems and algorithms.

The stability and electrochemical properties of a self-assembled layer of spinach ferredoxin on a quartz substrate and on a highly oriented pyrolytic graphite electrode were investigated. To fabricate the ferredoxin self-assembly layer, dimyristoylphosphatidylcholine was first deposited onto a substrate for ferredoxin immobilization. Surface analysis of the ferredoxin layer was carried out by atomic force microscopy to verify the ferredoxin immobilization. To verify ferredoxin immobilization on the lipid layer and to confirm the maintenance of redox activity, absorption spectrum measurement was carried out. Finally, cyclic-voltammetry measurements were performed on the ferredoxin layers and the redox potentials were obtained. The redox potential of immobilized ferredoxin had a formal potential value of -540 mV. It is suggested that the redox-potential measurement of self-assembled ferredoxin molecules could be used to construct a biosensor and biodevice.

Recent interests in total quality management (TQM) and business excellence (BE) had been fuelled with a range of national and regional awards. These awards are being increasingly used by organisations as part of the business improvement process and strategic benchmarking. This paper reviews the concepts and approaches of performance measurement (PM) and discusses the integration of PM with the TQM and BE philosophies. A TQM-BE-PM framework with a set of self-assessment checklists was developed. In order to complement the literature base with empirical evidence, an industry survey was conducted and a trial implementation of the framework was carried out in a leading manufacturing firm in Hong Kong. The self-assessment performance data of the fm was evaluated and then benchmarked with the industry averages obtained from the survey. This paper presents the empirical findings and discusses the applicability of the framework in measuring and benchmarking organisational performance toward continual improvement.

The paper proposes a model-based measurement of unsteady flow rate by using distributed parameter pipeline model and the measured pressure values at two distant points along the pipeline. The distributed parameter model of hydraulic pipeline is applied with consideration of frequency dependent viscosity friction and unsteady velocity distribution at a cross section of a pipeline. By using the self-diagnostics functions of the measurement method, the validity is investigated by comparison with the measured and estimated pressure and flow rate wave forms at the halfway section on the pipeline. The results show good agreement between the estimated flow rate wave forms and theoretical those under unsteady laminar flow conditions. The method proposed here is useful in estimating unsteady flow rate through an arbitrary cross section in hydraulic pipeline and components without installing an instantaneous flowmeter.

Purpose: The aim on this study was to establish the validity, reliability and efficiency of a Pain Self-Report Scale for elderly with dementia and compare these results with an observational pain rating scale. Methods: Study subjects were 136 elderly with dementia who were residents in a nursing home, geriatric hospital, or day care center. The subject's pain was measured by five self-report scales and observational scale. DS-DAT (discomfort scale-dementia of the Alzheimer's type) was used for pain behavior observational measure. Cognitive state was assessed using the MMSE (Mini-Mental State Examination). Results: Observational rating correlated moderately with self-report (r=.225~.585, p<.05) and tended to underestimate pain intensity. Test-retest reliability was high for all five self-report scales, and the correlation between these scales was very strong (r=.735~.856, p<.05). Comprehension rate of VDS (verbal descriptor scale) was 88.3%, and NRS (numeric rating scale) 69.9%, FPS (face pain scale) 66.9%, HVAS (horizontal visual analog scale) and VVAS (vertical visual analog scale) 65.4%. Conclusion: Nurses should not apply observational scales routinely in demented patients as many of these are capable of reporting their own pain. Self-report, the highest standard of pain measurement can be reliably performed in a large proportion of demented elderly.

A broadband self-recording hydrophone was developed to conveniently assemble a hydrophone array for use in receiving underwater sound waves. A trigger device with an electromagnetic induction coupler was also developed to control the hydrophone's operation. Main configurations and specifications of the self-recording hydrophone are introduced in this paper. We present experiment results conducted in a water tank to examine the operating behavior of the hydrophone. Some advantages are discussed when the self-recording hydrophones are used to make up a hydrophone array.

The purpose of this study is to investigate the relations between housewife's self esteem and attitude toward household work its satisfaction and to find out how independent variables(housewife's age, education level, employment, household work helper, type of family) have effect on the two dependent variables. The measurement of self-esteem was based on the self-concept test standarized by Jung Won Sick, reformed the Fitts measurement for Korean Society. In order to measure of attitude toward household work and its satisfaction, based on the previous research, researcher made the measurement . the research was conducted on 234 housewives in Seoul in September 1984. Data was analyzed by percentage, mean, frequence analysis of variances, Pearson's correlation coefficient. The result can be summarized as following. 1)Over on half of housewives have high self-esteem comparatively. 2) Age and education level were variables to have influence n the attitude toward household work. 3)The attitude toward household work and its satisfaction comparatively were high. 4)Education level and type of family were variables to have influence on the attitude toward household work. Education level, employment and household work helper were variables to have influence on the satisfaction of house hold work. 5) Level of Self-esteem has influence on the attitude toward household work and its satisfaction. The higher level of self-esteem was, the higher becomes the score of the attitude toward house hold work and its satisfaction. Following suggestions can be extracted form the results of above study. 1) research of housewife's self-esteem didn't established a setted theory yet. I think, therefore, it requires deeper study about housewife's household work look upon as her occupation and relation between the household work as her occupation and her self-esteem in this area. 2) Population and sociological variables, used in this study, hardly influenced on self-esteem, the attitude toward household work and its satisfaction. Also the result didn't correspond with one another. So I think it requires need of further study how psychological and family function variables will have influence on housewife's self-esteem, the attitude toward household work and its satisfaction. 3) To recognized the value of household work objectively, many researchers tried to investigate of economical value of household work, But if housewife can realize her self-actualization through household work, it requires the study that try to objectively not only estimate the economic value of household work, but also the contribution of the aspect of family psychology.
