This paper provides a review of the research on the relationship between consumer rumor and marketing management in general, and rumor's effects on brand in particular. Also corporations' efforts for managing negative rumor were discussed. In the subsequential article, this study analyzes the consumer's perception of the origin of rumors through contents analysis method, and performs ANOVA study in addition to identify if brand assets such as brand loyalty and brand involvement can affect rumor credibility perception significantly. Based on these results, this study considers some implications for brand crisis management and communications. According to the results, a brand rumor can affect both the corresponding brands and competitor's brands at a time and the relationships between existing favorable brand attitude of consumer and rumor credibility are not significant enough.

Both competent authorities and private entrepreneurs face plenty of risks when negotiating BTO(Build Transfer Operation) methods of PPI(Private Participations in Infrastructures) projects. Also, success and failure of projects largely depend on the concession agreement contract. In this study, for more efficient negotiation, major issues are examined, and quantitatively analyzed to find out not only the relationship but also the characteristics of which these issues share. Questionnaire research was conducted through both research and by experts who were divided into an ordering agency, design company and constructor. Characteristics of major issues were quantitatively analyzed using the Likert index method, ANOVA(ANalysis of VAriance) and AHP(Analytic Hierarchy Process) analysis. Case studies were examined in order to estimate construction cost, rates of return, government finance support, level of operation-revenues guarantees, estimating operational costs and usage fees. With these 6 items, relative priority, relative impression which is sensible to risk and extent of difficulty in presenting data which is objective were quantitatively analyzed by the ordering agency, design company and constructor groups. From the analysis, there were some similarities between the design company and constructor groups while there was less of similarities between the ordering agency and design company or constructor. The government is diversifying the methods of project promotion, and PPI project from infrastructure-centered to public culture facilities are being expand. The current study will provide not only supporting efficient negotiation but also revitalizing PPI projects.

This study aims to analyze the differences in performance according to various operation methods (direct management, public consignment, and private agency) of public sewage treatment facilities and derive the most efficient and high level of sewage treatment services to the public based on the research results. To this end, economic performance indicators (sewage treatment cost, sewerage rate) and social performance indicators (water quality, number of civil complaints) were selected, and cross-sectional analysis and longitudinal analysis were used to verify the difference between the averages of three or more groups through one-way ANOVA. As a result of the analysis, cross-sectional analysis, there was no difference in economic performance dimension according to the operating method, but in terms of social performance dimension, it was found that there was a difference according to the operating method. In the case of water quality indicators, the results were superior to those directly managed by public consignment and private agencies in the number of civil complaints. In the longitudinal analysis examining the improvement of performance indicators, there was no significant difference by operation method in most performance indicators. In order to improve the efficiency of public services and improve the service level, various approaches suitable for the characteristics of each service are required in addition to the logic of public consignment or introduction of private agency. In the future, when local governments promote public consignment or private agency, it is necessary to understand and promote the nature of the service, the specificity of each local government, and the needs of service users.

Bearing is one of the important mechanical elements used in various industrial equipments. Most of failures occurred during the equipment operation result from bearing defects and breakages. Therefore, monitoring of bearings is essential in preventing equipment breakdowns and reducing unexpected loss. The purpose of this paper is to present an online monitoring method to predict bearing states using vibration signals. Bearing vibrations, which are collected as a form of profile signal, are first analyzed by a discrete wavelet transform. Next, some statistical features are obtained from the resultant wavelet coefficients. In order to select significant ones among them, analysis of variance (ANOVA) is employed in this paper. Statistical features screened in this way are used as input variables to support vector machine (SVM). An hierarchical SVM tree is proposed for dealing with multi-class problems. The result of numerical experiments shows that the proposed SVM tree has a competent performance for classifying bearing fault states.

The objective of this study is to verify the effects of the application of flossband to the ankles of healthy adults on the functional range of ankle and walking ability. Total 20 people participated in the experiment, and through the randomization, one foot was set up as experimental side while the other foot was set up as control side. To analyze the two factors(before/after intervention/experimental side and control side), the two way-repeated ANOVA was conducted. The significance level was set up as 0.05. In the results of this study, compared to the control side, the experimental side showed significant increase in WBLT and heel strike(p=.05). In the test before/after intervention, the experimental side showed significant increase in WBLT, heel strike, and toe off(p=.05). The control side showed significant increase in toe off(p=.05). Thus, the application of floss band on ankle joint performed in this study would be helpful for improving the functional range and walking ability in the sports & rehabilitation field.
