  • Purpose: This study was designed to investigate the effects of voxel size, the oversampling technique, and the direction and area of measurement on modulation transfer function (MTF) values to identify the optimal method of MTF measurement. Materials and Methods: Images of the wire inserts of the SedentexCT IQ phantom were acquired, and MTF values were calculated under different conditions(voxel size of 0.1, 0.2, and 0.3 mm; 5 oversampling techniques; simulated pixel location errors; and different directions and areas of measurement). The differences in the MTF values across various conditions were evaluated. Results: The MTF 10 values showed smaller standard deviations than the MTF 50 values. Stable and accurate MTF values were obtained in the 0.1-mm voxel images. In the 0.3-mm voxel images, oversampling techniques of 11 lines or more did not show significant differences in MTF values depending on the presence of simulated location errors. MTF 10 values showed significant differences according to the direction and area of the measurement. Conclusion: To measure more accurate and stable MTF values, it is better to measure MTF 10 values in small-voxel images. In large-voxel images, the proper oversampling technique is required. MTF values from the radial and tangential directions may be different, and MTF values vary depending on the measured area.

  • The aims this paper to examine Nietzsche's criticism on Paul's transvaluation of values. First, I will examine Socrates' transvaluation of values through which, Greek culture was deconstructed. He opened a path for the transvaluation of values before Paul and Nietzsche and reorganized Greek culture around his own values. I will also analyze the 'will to power' hidden behind Socrates' transvaluation of values. Second, I will examine the essence of the Paul's transvaluation of values. I will trace how Paul, through his transvaluation of values, could become the center of Christianity and, in turn, control European Culture. I will also show the difference between the teachings of Jesus and the arguments of Paul. Third, I will look at the Nietzsche's criticism on Paul's transvaluation of values. The key to Nietzsche's criticism on Paul is to evaluate Paul's transvaluation of values in terms of his will to power. And I will also look at the problems of Nietzsche's criticism on Paul. Fourth, I will look at Nietzsche's transvaluation of values. It is accomplished in such a way that he makes Socrates' and Paul's transvaluation of value alters. His transvaluation of values will be critically examined for strength in life and world understanding over Socrates' and Paul's transvaluation of values.

  • Recently, a new kind of multiple zeta value of level two T(k) (which is called multiple T-value) was introduced and studied by Kaneko and Tsumura. In this paper, we define a kind of alternating version of multiple T-values, and study several duality formulas of weighted sum formulas about alternating multiple T-values by using the methods of iterated integral representations and series representations. Some special values of alternating multiple T-values can also be obtained.

  • This paper proposes a modified category framework derived from VAMP and VIMT projects for describing teachers' mathematical and pedagogical values, and examines the dialectical relations between values awareness/willingness and teaching, based on case studies of student teachers of secondary mathematics from a follow-up project of VIMT. The preliminary results show that student teachers would teach certain values depending on the awareness of values priority, willingness to teach, their teaching capabilities and classroom conditions. So, mathematics teacher educators should provide relevant courses to facilitate student teachers to be aware of their implicit values and be willing to enact these values, and to empower student teachers with the knowledge and experiences to teach the values.

  • The main goal of this study was to demonstrate the causal relationships between multi-dimensional work-values, job satisfaction and task performance of Y generational employee in the Korean hotel industry. In order to achieve the purpose, the data were collected from Y generational employees working in the major cities in Korea. To analyze the data, frequency, exploratory factor analysis, reliability analysis, PROCESS Macro analysis and simple regression analysis were undertaken by using SPSS 18.0. The results were as follows; 1. Work-values were found out as five factors; Prestige workvalues, Personal development work-values, Work condition work-values, Personal welfare work-values, Social/ Altruistic work-values. 2. All five factors were found to be significant in enhancing job satisfaction. 3. Two factors which were prestige work-values and personal welfare work-values were found to be significant in facilitating task performance. 4. Job satisfaction was revealed as a mediator between all work-value factors and task performance. This study provided practical information about work-values of Y generational hoteliers to positively affect their job satisfaction and task performance. This study also confirmed that it is important to enhance job satisfaction in order to make employees perform their service duties better.

  • Consumers are becoming increasingly interested in what kind of value their food has. Many studies have focused on consumers' preferences and willingness to pay for specific food values. However, few studies have asked consumers to consider or rank the importance of different food values. This paper determined consumers' food values by implementing the best-worst scaling approach and segmented consumers based on the relative importance of general food values that consumers place on them. Among a list of eleven food values (taste, safety, origin, appearance, price, environmental impact, naturalness, convenience, nutrition, fairness, and habit) which was compiled from previous studies on food preferences, on average, safety, nutrition, taste, and price were the most important values to consumers, whereas fairness, habit, appearance, convenience, origin, and environmental impact were the least important values. However, significant variation exists among consumers in terms of the relative importance of food values. To investigate the heterogeneity among consumers, a Latent Class Analysis was performed to classify consumers into subgroups based on responses to questions. Two latent classes were found and characterized as 'safety-nutrition' and 'taste-price'. The 'safety-nutrition' cluster represents 61% of the sample and a group of people who find safety and nutrition centered values to be the most important. Another cluster represents about 39% of the sample, and relative to the first group, this group finds price and taste values to be more important.

  • This study examined the mediating effect of management's values on organizational performance and between them. Hypotheses 1, 2, 3, and 4 which were set up to achieve the purpose of this study, were verified as follows. First, Hypothesis 1 proposed that the values of management will have a positive effect on organizational performance. Second, Hypothesis 2 proposed that the values of management are likely to have a positive effect on the consistency of the values of organizational members. Third, Hypothesis 3 proposed that the consistency of the values of organizational members will have a positive (+) influence on organizational performance. We found that the consistency of the values of organizational members has a positive (+) influence on organizational performance. Hypothesis 3 was adopted. Fourth, hypothesis 4, the value consistency of the members of the organization, had a mediating effect between the organization performance on value management. The results of this study were all adopted research hypotheses. Therefore, management's values have a significant impact on the theoretical and practical aspects by showing the relationship between organizational members' value consistency and organizational performance. In the future, the necessity of further research on management's values and member's value consistency through various fields for organizational performance has emerged.

  • Background: Health, safety, and well-being (HSW) at work represent important values in themselves. It seems, however, that other values can contribute to HSW. This is to some extent reflected in the scientific literature in the attention paid to values like trust or justice. However, an overview of what values are important for HSW was not available. Our central research question was: what organizational values are supportive of health, safety, and well-being at work? Methods: The literature was explored via the snowball approach to identify values and value-laden factors that support HSW. Twenty-nine factors were identified as relevant, including synonyms. In the next step, these were clustered around seven core values. Finally, these core values were structured into three main clusters. Results: The first value cluster is characterized by a positive attitude toward people and their "being"; it comprises the core values of interconnectedness, participation, and trust. The second value cluster is relevant for the organizational and individual "doing", for actions planned or undertaken, and comprises justice and responsibility. The third value cluster is relevant for "becoming" and is characterized by the alignment of personal and organizational development; it comprises the values of growth and resilience. Conclusion: The three clusters of core values identified can be regarded as "basic value assumptions" that underlie both organizational culture and prevention culture. The core values identified form a natural and perhaps necessary aspect of a prevention culture, complementary to the focus on rational and informed behavior when dealing with HSW risks.

  • The purpose of this present study is not only to investigate mutual relationship between general values and clothing behaviors, but to analyize the differences in clothing behaviors in view of socio-economic backgrounds, such as professions, social classes, educational levels, monthly income, etc. For the measurement of the general values, a total of 45 questions were made use of from both part I and part II of 'The study of General Values' jointly developed by Allport-Vernon-Lindzey, while for the measurement of the clothing behaviors were used questions selected from 'The clothing variables Inventory' developed by Creekmore and from those previously used in our country for the same purpose. Data were obtained from 460 Persons and the selected sample was composed of 238 Persons from the upper class and of 222 persons from the lower class. The former class is mainly represented by government officials, doctors, company directors, professors, while the latter by factory workers, clerks, drivers. Analysis of the data in this present study reached its conclusions as follows ; 1. Among the general values valiables, the selected group in this study ranked, theoretical values' first, 'political values' 'econmic values', 'social values', aesthetic values', 'religious values' in that order, and also among the clothing behaviors variables it ranked in the following order ; economy' 'modesty' 'aesthetic' 'conformity' 'status symbol'. 2. A significant relationship between general values and clothing behaviors was found as follows ; there are negative relationships between 'theoretical values' and 'aesthetic', 'status symbol', between 'aesthetic values' and 'conformity', between 'social values' and 'status symbol', between 'political values' and 'conformity', on the one; there are positive relationships between political values' and 'status symbol', between religious values' and 'aesthetic', on the other, 3. In view of profession, it was found that a group of company directors placed the most importance upon 'status symbol', a group of factory workers upon 'economy', a group of drivers upon 'conformity' among the clothing behaviors. In light of social classes, 'economy' was given a high priority by the lower class, and 'status symbol' by the upper class, respectively. Considering educational levels, it was found that the highly educated class placed more emphasis on 'status symbol' and the lower educated class showed their preference to 'economy'. In view of monthly pay, 'conformity' was given a top priority by the middle class, and 'status symbol' by the upper class. 4. As a result of investigating the influence that one's age and marriage effect on clothing behaviors, significant differences were found among the three clothing motivations of 'aesthetic', modesty', 'status symbol'.
