In order to maximize the effect of TQM in the Korean industry, quality circle activity as a bottom­up management should be expanded and revitalized. Quality circle activity can be regarded as a kind of knowledge activity where new knowledge is created and knowledge is shared in the economy. This paper proposes new metrics of intangible effect as knowledge assessment focusing on the intellectual capital aspect of quality circle activity, that may be useful for revitalizing quality circle activity from viewpoints not only of financial effect but also of intellectual capital aspect. New metrics of intangible effect consist of two factors： the intellectual capital effect and the intellectual maturity effect. In order to test the validity of new metrics, a case study of 11 companies was done. The result of the case study is that two factors as an intangible effect of quality circle activity should be evaluated to identify the total effect of quality circle activity correctly.

In this study, to raise the scientific literacy for students, the teaching and learning program was developed by applying the Circle Map. The purpose of this study was to find out the Effect of Elementary Science Teaching Program with Circle Map on Learning Motive and Learning Achievement. To this end, the 6th grade classroom of A-elementary school located in Jeju-city was selected the experimental group (25 patients). And the other 6th grade classroom in the same school was selected to the comparative group (25 patients). The experimental group was conducted applying the Circle Map. Comparison group has been conducted lesson program in accordance with the general science class teacher guide. Was through a pre-test of science learning motivation and academic achievement level can be assumed in the same group. After completing the experimental treatment by conducting a post-mortem examination was statistically validated. In this study, the following conclusions were obtained. First, elementary science class which applied Circle Map had the effect of to improve the scientific motivation(p <.05). In particular, association in the experimental group were higher than the scores of the comparative group, the difference was significant. Second, the Circle Map applied to elementary science class had a significant effect on improving science achievement. The experimental group which applied Circle Map was higher than the comparative group in science achievement post-test comparison. Between the groups showed a significant difference between the two groups(p <.05). The above findings, Elementary science class which applied Circle Map can be concluded to be effective in science and science achievement motivation. Therefore, applying the Circle Map of elementary science class could be useful in science teaching and learning methods. In addition, when it is determined through the previous study, applying the Circle Map classes will be able to derive a meaningful learning also subjected to a number of fields and areas.

With the rapid development of the Internet and the Mobile Internet, social communication based on the network has become a life style for many people. WeChat is an online social platform, for about one billion users, therefore, it is meaningful to study the spreading and evolution mechanism of the rumor on the WeChat social circle. The Rumor was injected into the WeChat social circle by certain individuals, and the communication and the evolution occur among the nodes within the circle; after the refuting-rumor-information injected into the circle, subsequently,the density of four types of nodes, including the Susceptible, the Latent, the Infective, and the Recovery changes, which results in evolving the WeChat social circle system. In the study, the evolution characteristics of the four node types are analyzed, through construction of the evolution equation. The evolution process of the rumor injection and the refuting-rumor-information injection is simulated through the structure of the virtual social network, and the evolution laws of the four states are depicted by figures. The significant results from this study suggest that the spreading and evolving of the rumors are closely related to the nodes degree on the WeChat social circle.

Objective: The objective of this study was to examine frame ratio of text information and font size in the circle smartwatch. Background: Recently, electronic manufacturers try to develop the original metaphor of traditional wrist watch (circle) in terms of smartwatch. They endeavor to break the square display in order to improve emotional customer satisfaction. Method: The experiments examined twenty level of text information design, combinations of four frame ratios (1:1, 4:3, 16:9, 21:9) and five font sizes (6pt, 7pt, 8pt, 9pt, 10pt). Nineteen participants volunteered for the experiment. Dependent variables were WPM (Words per Minute), reading preference, design preference and total preference. Furthermore, small circle display was made by using circle display data (1.3inch), which was exhibited in IFA (International Funkausstellung) 2014. Results: As a result, ANOVA (Analysis of Variance) revealed that WPM, and task time preference affect the specific frame ratio and font size. Results of ANOVA for reading preference, design preference, total preference were grouped by post-analysis LSD (Least Significant Difference). Among users, display ratio (16:9, 21:9), and font size (9pt) were preferred. In conclusion, 16:9 display ratio and 9pt are adaptable for text information in 1.3inch circle display. Conclusion: From the study, it is shown that 16:9 display ratio and 9pt size are more adaptable for text information in 1.3inch circle display than others. It is mainly due to the fact that the order of frame ratio and font size may affect the usability of reading long text information in a small circle display. Therefore, when developers design a circle display, the square frame ratio and font size are required to be considered according to circle size. Application: The 16:9 display ratio and 9pt font size may be utilized as a text information frame in the circle display design guideline for smartwatch.

A navigator on bridge needs to know every kinds of motion characteristics of his vessel at sea. Generally when a vessel is completely built, the shipyard makes turning circle diagrams from the results of turing circle tests made during the sea trials for the reference of the vessel's owner. But referring only the data of a turning circle diagram, an officer on bridge can not figure out his vessel's maneuvering characteristics sufficiently, So nowadays the shipyard often adds Z test to turning circle test for more detail references. In this paper the author made Z and turning circle tests at the rudder angles of 15 and and 35 degress separately and in each of the case made a turrning circle diagram from the results of the turning circle test and the esults numerically calculated from mathematical formula made on the base of the maneuvering indices got from the Z test and compared them each other for the purpose of finding the correlations between them. Followings are concluded from the results. An actual turning circle diagram and a calculated one from the results of the Z test at same rudder angle coincides each other well when the center of the calculated circle is transferred by 1.7B toward the direction of the initial turning perpendicularly to the original course and 0.5L toward the direction in parallel with original course in case of the rudder angle of 35 degrees and 1.2B and 0.3L toward each of the above mentioned directions in case of rudder angle of 15 degrees.
