  • We investigate Faraday rotation measure (RM) toward high Galactic latitudes due to the Galactic magnetic field (GMF). The Galactic contribution to RM comes from the global component and the turbulent component of the GMF, and we newly model the latter by incorporating data of MHD turbulence simulations. We find that for the turbulent velocity of ~50 km/s, the standard deviation of the RM due to the GMF toward high Galactic latitudes is close to the observed value, several rad m^{-2}. Yet, the predicted second-order structure function (SF) has values substantially smaller than the observed ones at separation angles of <~ several degree. This suggests that the intergalactic magnetic field (IGMF) significantly contributes to RM toward high Galactic latitudes, particularly at small angular scales. Our work proposes a strategy for surveys to explore the IGMF with LOFAR, ASKAP, MeerKAT, and SKA.

  • Consumers use a variety of decision making styles. The purpose of this was to identify the decision making styles of fashion leaders. Self-report scales were used to measure fashion leadership and decision making styles for 236 female college students. The data were analyzed using factor analysis and t-tests. The results indicated that fashion leaders have unique decision making styles of recreational shopping/fashion conscious, brand-loyal and high quality conscious. The implications of these findings for fashion merchandising are discussed.

  • Soft materials, such as polymer solutions, gels and filamentous protein materials in cells, show complicated behavior due to their complex structures and dynamics with multiple characteristic time and length scales. Several complementary techniques have been developed to measure viscoelastic of soft materials. Especially, particle tracking microrheology, using the Brownian motion of particles in a medium to get rheological properties, has recently been improved both theoretically and experimentally. Compared to other conventional methods, video particle tracking microrheology has some advantages such as small sample volume, detecting spatial variation of local rheological properties, and less damage to sample materials. With these advantages, microrheology is more suitable to measure the properties of complex materials than other mechanical rheometries.

  • Service quality is defined as the perceived difference between performed service and expected service. In this paper, theme park service quality is conceptualized in relation to consumer's total satisfaction on theme park visitation. A 20-item scale was constructed to measure Theme Park Service Quality. The following four steps were employed in developing the service quality measure: 1)identification of service quality dimensions, 2)development of scales from a set of items describing the dimensions, 3)empirical verification of the scale's construct validity which refers to dimensionality, convergent validity, and nomological validity, and 4)confirmation of the utility. The scale was found to be an empirically valid and reliable evaluation tool for service quality enhancement. In addition, the scale would be an useful criterion for market segmentation and positioning.

  • In this paper, we have studied scale tools for measure programming task value and learning persistence at elementary school students. In order to develop complete test tools, we have improved the completeness by revising tests through stepwise verification. The first scales were constructed based on the previous studies. As a result of the content validity test, 5 out of 14 items of the task value test tool and 1 out of 10 items of the learning persistence test were not suitable. The second test tools were constructed by revising and supplementing the first scale, and consisted of 13 items of task value and 8 items of learning persistence. As a result of the contents validity test, all the items included in the test tool proved to be valid. The reliability of the secondary testing tools were also found to be reliable at ${\alpha}=.970$ and ${\alpha}=.975$, respectively.

  • It is very important to measure linear cycle plane positioning accuracy of NC lathe as it effects all other parts of machines machined by them in industries. If the plane positioning accuracy of NC lathe is bad, the dimension accuracy and the change-ability of works will be bad in the assembly of machine parts. In this paper, computer software systems are organized to measure linear cycle plane positioning displacement of ATC(Automatic tool changer) on zx plane of NC lathe using two linear scales. And each sets of error data obtained from the test is descriptions to plots and the results of linear cycle plane positioning errors are expressed as nutriments by computer treatment.

  • Patients satisfaction continues to receive attention as a measure of the outcome of physical therapy intervention. This study measures patient satisfaction among physical therapists' patients and clients and to identify factors of patient satisfaction that will affect patients decision. The instrument developed by Goldstein et. al(2000) was used. PAtients' opinions of service in each domain were measured using 5-point Likert-type scales. A 20-item instrument designed to measure the domains of patient satisfaction and 8 additional items were included. Data were collected at 8 hospital in Kwang-ju city Descriptive statistics, reliability, ANOVA, cross-tabs and regression analysis were computed. A total 365 individuals completed the instrument. Waiting time, treatment and cost domain predicted the satisfaction of physical therapy

  • While equity theory started as a theory focusing upon the relationship between employee and employer, over the years the theory has been expanded to various other types of relationships including marital relationships. The present research among 251 housewives examines the perception of equity and the decision-making styles from the perspective of equity theory. The perception of equity was measured by the revised TUW scales and the Walster's global measure. Also, decision-making styles was assessed by means of the 'final-say' scale In line with the predictions, the results clearly showed that the perception of equity was a strong predictor variable to the joint decision-making.

  • Pixel classification is one of basic image processing issues. The general characteristics of the pixels belonging to various classes are discussed and the radical principles of pixel classification are given. At the same time. a pixel classification scheme based on image direction measure is proposed. As a typical application instance of pixel classification, an adaptive multi-level median filter is presented. An image can be classified into two types of areas by using the direction information measure, that is. smooth area and edge area. Single direction multi-level median filter is used in smooth area. and multi-direction multi-level median filter is taken in the other type of area. What's more. an adaptive mechanism is proposed to adjust the type of the filters and the size of filter window. As a result. we get a better trade-off between preserving details and noise filtering.

  • The purpose of this study was to development of the 'convergence motive' scale for interdisciplinary knowledge fusion. Based on results from literature review, this study clarifies a theoretical ground for 'convergence motive'. Initial items to measure this concept were verified by content analysis and then finalized. After a pilot test done with 568 college students, gathered data were analyzed by item selection and exploratory factor analysis to verify their validity. Next, the main test implemented with 1,211 college students was analyzed with exploratory factor analysis using the method for rotation based on maximum likelihood analysis and direct oblimin for validating the final items to measure 'convergence motive'. As a result, the scale for 'convergence motive' consists of 43 items to measure the following four factors: collaboration to identifying and solving problems, challenge of a new perspective, communication for convergence, cohesion for convergence. Construct validity and criterion-related validity were performed at last to check this scale's theoretical construct. In conclusion, this study concluded that the scales for convergence motive could be generalized and applicable to other samples.
