  • Purpose: The purpose of this study was to identify and evaluate outcome measurement scales of nursing education such as communication, professionalism, leadership, and critical thinking. Methods: A methodological study design was used to evaluate the reliability and validity of the scales. Survey was done to the students (n=407) enrolled in baccalaureate nursing schools. Using convenience sampling method, we tried to include all grades of students. Internal consistency, convergent validity and group comparison were used to evaluate the reliability and validity of the scales. Results: All scales were reliable and valid. Only convergent validity of the scale to measure critical thinking was relatively low. It suggested that critical thinking skill and disposition might be measured separately. Also it was inefficient to measure the nursing education outcomes with separate scales. Conclusions: It is recommended to develop a new integrative scale to measure nursing education outcomes. Also it is necessary to set the norm of nursing students to evaluate nursing education outcomes for the quality control of nursing education.

  • In this paper error-compensating techniques in three-point weighing method to precisely measure unbalance properties such as center of gravity and unbalance moment. In the conventional static methods, 1) fixture-errors, 2) effects of the contact between the fixture and the load scales, and 3) side effect due to the lateral frictional forces acting on the contact points between the fixture and the load scales are the major factors that lead to measurement errors. The proposed error-compensating method perfectly eliminates both the fixture-error and the contact-error simultaneously by manipulating the three measured reaction forces at three different angular locations. Also the friction-error is calibrated by comparing the sum of three reactions with the actual mass of the specimen. A set of measurement is performed using the same measuring system as Lee's, and a comparison of the results from the convectional, Lee's, and the proposed method is provided. The results show that the proposed method effectively compensates the errors listed above.

  • Pain is subjective, while statistics related to pain research are objective. This review was written to help researchers involved in pain research make statistical decisions. The main issues are related with the level of scales that are often used in pain research, the choice of statistical methods between parametric or nonparametric statistics, and problems which arise from repeated measurements. In the field of pain research, parametric statistics used to be applied in an erroneous way. This is closely related with the scales of data and repeated measurements. The level of scales includes nominal, ordinal, interval, and ratio scales. The level of scales affects the choice of statistics between parametric or non-parametric methods. In the field of pain research, the most frequently used pain assessment scale is the ordinal scale, which would include the visual analogue scale (VAS). There used to be another view, however, which considered the VAS to be an interval or ratio scale, so that the usage of parametric statistics would be accepted practically in some cases. Repeated measurements of the same subjects always complicates statistics. It means that measurements inevitably have correlations between each other, and would preclude the application of one-way ANOVA in which independence between the measurements is necessary. Repeated measures of ANOVA (RMANOVA), however, would permit the comparison between the correlated measurements as long as the condition of sphericity assumption is satisfied. Conclusively, parametric statistical methods should be used only when the assumptions of parametric statistics, such as normality and sphericity, are established.

  • This review focuses on the individual performance and productivity of researchers in the area of science and technology. The researchers in the paper are classified into individual inventors without organizational affiliation and researchers in the organization, which are distinguished by cosmopolitanic professionals and local institutionalists. The productivity of researchers is in general measured by different indicators or measurement scales such as: i) subjective evaluation of overall research performance, (ii) the number of published papers, reports and books, iii) the quality of research output (e.g. citation frequency), iv) originality of research ouput (e,g, patents), v) multiple measurement scales, etc. According to the literature based on empirical study, the productivity of individual reseachers is positively related to the degree of freedom, communication, diversity, dedication, and motivation and negatively related to the degree of similarity, and satisfaction. However, other factors such as creativity, age, supervisory behavior and group characteristics have shown irregular direction of correlation.

  • The micrometeorological tower flux network is the cornerstone of the global terrestrial vegetation monitoring. The eddy covariance technique used for tower fluxes is derived from the conservation of mass and is most applicable for steady-state conditions over flat, extended, and uniform vegetation. This technique allows us to obtain surface fluxes of energy budget components, greenhouse and trace gases, and other pollutants. The quality-controlled flux data are invaluable to validate various models with temporal scales ranging from minutes to years and spatial scales ranging from a few meters to hundreds of kilometers. In this paper, we review the theoretical background of this important eddy covariance technique, examine the measurement criteria and corrections, and finally suggest some measurement strategies that may facilitate coordinated flux measurements among different disciplines and provide a strong infrastructure for the global flux network.

  • It is known that human factors account for 80 percent of all railway accidents. To reduce human errors must be the most efficient shortcut to railway safety. For public transportation employees like railway, the more delicate safety management should be executed in individual level. However, there are rarely efforts to improve safety performance of workers who are the subject operating the railway system. This paper develops a hierarchy model to evaluate the human safety performance in railway industry. To evaluate the model, AHP (Analytic Hierarchy Process) methodology is adopted. The hierarchy model is composed of four levels which are objective, two criteria, specific factors of criteria, and rating scales. In addition, since employees for evaluation are over 10, the pairwise comparisons for rating scales are carried out by the absolute measurement. We explore the applicability of AHP to the performance evaluation of railway safety workers by an example and also investigate the changes of alternatives that are railway employees according to the changes of human characteristic which is one of criteria.

  • Objectives : The knee pain is the main reason of getting acupuncture treatment. In order to have confidence in the results of a study, it is necessary to establish that questionnaire is both valid and reliable in questionnaire related study. The aim of this study was to review the instruments that are currently in sue for assessing the knee joint. Methods : A literature study was performed to choose appropriate scales for assessment for pain and the function of the knee. Theoretically based scales were selected for review. Therefore, 18 scales for knee and 9 scale for pain were reviewed. the status of scales involved in knee treatment of acupuncture throughout several countries was evaluated. Results & Conclusion : Lysholm Knee Scoring Scale, Cincinnati knee rating system(CKRS) are adequate for ligament injury in knee. International Knee Documentation Committee scoring system(IKDC) may become a publication requirement for journals in view of the international standing of the committee. The available outcome measure for use in osteoarthritis are Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), Lequesne Functional Severity Index(LFI) and Knee Injury and Osteoarthritis Outcome Score(KOOS), and in rheumatoid arthritis are McMaster-Toronto Arthritis patient function preference questionnaire(MACTAR), Quality of Life-Rheumatoid Arthritis Scale(QoL-RA Scale). Visual analog scale(VAS), verbal rating scale(VRS) are commonly used for the standard pain scale. For long term follow-up study The Medical Outcomes Study Short Form-36(SF-36), Arthritis Impact Measurement Scales(AIMS), Health Assessment Questionnaire(HAQ) should be included. Each measurement has its own composition and characteristics. Their validity, reliability, responsiveness and practical characteristics were already evaluated. We found 20 domestic and 28 overseas papers about knee treatment using acupuncture assessed with knee scales.

  • The purpose of this study was twofold: (1) to design a system for constructing Likert attitude scales as supported by the sociopsychological and measurement literature, and (2) (using the design) to develop an affective component of "Attitudes toward Science" scale for high school students. The rationale for developing a new attitude scale is presented in the context of a review of existing attitude scales. As discussed in the literature review, many existing attitude scales are based on ill-defined theoretical constructs, and includes statements that do not appear to be assessing a single construct of attitude toward science. In addition, existing attitude scales do not distinguish between affective and behavioral and cognitive components of attitude toward science. Thus, this study was to carefully define the construct, subcomponents of attitude toward science, and develop an affective component of "Attitude toward Science" scale to reflect the construct and to distinguish between affective and behavioral and cognitive components of attitude toward science. The results of this study: (1) three-mains step for designing reliable and valid attitude scale were developed, and (2) 35 items(16 positive and 19 negative) for an affective component of "Attitudes toward Science" scale with the following characteristics were developed: (a) The internal consistency was estimated using Cronbach's coefficient ${\alpha}$, 0.9727. (b) The range of adjusted item-total correletion(${\gamma}$-value) were 0.58${\sim}$0.83. (c) The correlation coefficient ranged between 0.61 and 0.74 revealing a moderate relatedness between subcomponents. (d) The correlation coefficient for concurrent validity were 0.55 with TOSRA and 0.51 with SAl.

  • In spite of the increasing significance on a scale of building measurement unit and its system having been used in many areas of architecture, only a few researchers carried out the studies on a specific period. It is even harder to find a research results dealt in view of architecture. This research gives a focus on different types of scales employed in the ancient buildings and their sites, based on the research results of unit scale or scales found in recent excavations. After the review of literature on the scales widely used in the ancient times and of the various types of scales excavated archeologically, a kind of scale unit system that had been widely and extensively employed throughout the period of 'Three Kingdoms' could be revealed. The scale system is possibly able to be applied to estimate the exact scale of buildings and their sites as well in that era. The research results show that the scale and its system employed in the East and West buildings and their sites of 'Kum-dang' in 'Mi-ruk Sa' temple are different from 'Kokuryo' scale that was believed in to be used in the temple. Contrary to the suggestion by excavation report on the type of scale employed in the buildings their sites, a scale of 29 centimeters, similar to that of Tang, was employed. It was also found that one module consists of three 'Chuk's of 88.8 centimeters. Based on this scale system, we could conclude that three modules of the buildings on the front and two and half modules of them on the sides were explained by this scale and its system.
