The purposes of this study were to examine the two processes of social comparison and self-comparison, and to suggest the applications of social comparison theories and self-comparison theories. For these purposes, social comparison theory, self-evaluation maintenance model, control theory, self-discrepancy theory, regulatory focus theory, and temporal comparison theory were reviewed. The processes of social comparison and self-comparison are different, but both comparisons are similar in that they have some effects on self-evaluation, emotion, motivation and behaviors. Suggestions on education, health, economic justice and interpersonal relationships were discussed.

The study investigated the effects of SNS usage on 20s and 30s female SNS users' internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders based on objectification theory and social comparison theory. The study examined differences on SNS usage and body image variables between high and low groups of SNS envy and self-compassion. Social Network Service (SNS) is used as a contemporary marketing tool for brands and companies. It also influences the body image of female SNS users. The survey used an online survey company for female SNS users in their 20s and 30s to analyze the effect of SNS usage. The results showed that SNS usage significantly impacted the internalization of a thin body, body surveillance and appearance upper comparison. The internalization of thin body also had a significant impact on body surveillance and appearance upper comparison. Appearance upper comparison positively affected body dissatisfaction and eating disorders. Finally, the group with higher SNS envy showed higher SNS usage, internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders. The group with higher self-compassion showed opposite results. This study provided a theoretical expansion for a SNS and female body image study with objectification theory and social comparison theory. It also suggests positive SNS marketing strategies use for brands. Lastly, this study emphasized the importance of the proper use of SNS to protect the body image of SNS users.

Comparison challenge approach is proposed as a form of challenger-activated. just-in-time Internet advertising. To develop a framework for a comparison challenge, we propose a theory of comparison value. A comparison is regarded valuable if a comparison opportunity is available and if the comparison is relevant and informative, has an appropriate level of detail, and is advantageous and trustworthy. Based on this theory, the CompareMe and CompareThem strategies are devised, and comparable objects are classified in terms of price and performance dominance as well as the scope of proximity. The idea is demonstrated with a comparison of PCs from five leading manufacturers. To assist in the planning of the comparison challenge, a mathematical programming model was formulated to maximize the value of comparison under the constraints of the comparison opportunity and budget. The model is applied to eight scenarios in terms of the range of comparing objects. The models under various scenarios are tested and contrasted with the real-world example of PCs. We found the ad effect of comparison challenge to be substantially better than banners (4.75 times) and similarity-based comparisons (2.77 times), providing customers with better performance and reduced prices.

This study presents the rationale for the development of the Comparison Level Scale(CLS) and the Comparison Level for Alternatives Scale(CLAS). Data from 130 married women who live in the U.S.A. suggest that the CLS and the CLAS are internally consistent and unidimensional. The CLS and the CLAS are based on exchange theory perspectives, particularly, Thibaut and Kelley's theory, on evaluating an individual's comparative processes. The scales provide explanatory as well as descriptive power concerning evaluating an intimate relationship.

The telegrapher's theory was used to develop a new formulation for the neutron noise equation. Telegrapher's equation is supposed to demonstrate a more realistic approximation for neutron transport phenomena, especially in comparison to the diffusion theory. The physics behind such equation implies that the signal propagation speed is finite, instead of the infinite as in the case of ordinary diffusion. This paper presents the theory and results of the development of a new method for calculation of the neutron noise using the telegrapher's equation as its basis. In order to investigate the differences and strengths of the new method against the diffusion based neutron noise, a comparison was done between the behaviors of two methods. The neutron noise based on SN transport considered as a precision measuring point. The Green's function technique was used to calculate the neutron noise based on telegrapher's and diffusion methods as well as the transport. The amplitude and phase of Green's function associated with the properties of the medium and frequency of the noise source were obtained and their behavior was compared to the results of the transport. It was observed, the differences in some cases might be considerable. The effective speed of propagation for the noise perturbations were evaluated accordingly, resulting in considerable deviations in some cases.

This paper presents a new approach to risk comparison in uncertain environment. Based on the uncertainty theory, some uncertain risk measures and risk comparison rules are proposed. Afterward the bridges are built between uncertain risk measures and risk comparison rules. Finally, several comparable examples are given.

Purpose: This study was aimed to evaluate the effects of a maternal education program based on the temperament theory on the temperamental goodness-of-fit between mother and child. Method: The research method was a nonequivalent, control group, non-synchronized design and the experimental period was from May 10, 2004 to July 24, 2004. The subjects were mothers who had children 3-4 years old who registered in eight kindergartens or infant schools in M city. Among the total 94 subjects, 47 were allocated as an experimental group and 47 were a control group. Using the SPSS/WIN 10.0 program, the data was analyzed by a Chi-square test, and t-test. Result: 1. After treatment with a maternal education program based on the temperament theory, the experimental group significantly decreased in scores for perceived children's behavior problems in comparison to the control group(t=-4.01, p<.001). 2. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for parenting stress in comparison to the control group(t=-.85, p=.40). 3. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for rejective parenting behaviors in comparison to the control group(t=-1.32, p=.19). Conclusion: A maternal education program based on the temperament theory is a useful intervention to decrease perceived children's behavior problems.

For practical calculations, the Reynolds equation is frequently used to analyze the lubricating flow. The full Navier-Stokes Equations are used to find validity limits of Reynolds equation in a lubricating flow regime by result comparison. As the amplitude of wavy upper wall increased at a given average channel height, the difference between Navier-Stokes and lubrication theory decreased slightly : however, as the minimum distance in channel throat increased, the differences in the maximum pressure between Navier-Stokes and lubrication theory became large.
