Objectives: To identify the factors associated with the intention to undergo mammography among Korean women without a prior screening experience. Methods: Among 1,039 women of the general population, we selected 145 women (mean age: 54.2 years, age range : 40-78 years) without any prior experience with mammography. They were recruited for the 'Cancer Information Needs Assessment Survey' by using the method of random multi-stage cluster sampling. Data on the socio-demographic characteristics, intention to undergo mammography based on the Precaution Adoption Process Model, level of self belief and self efficacy for breast cancer screening, motivation for decision to undergo breast cancer screening were obtained by conducting a household survey. Results: Of the study subjects, 49.7% were classified as "unengaged" and "decided not to act" regarding breast cancer screening. Women with the intention to undergo mammography were more likely to be younger (OR 0.11, 95%CI 0.04-0.36), to have been recommended to undergo screening by others (OR 3.27, 95%CI 1.36-7.87), to have a high level of perceived sensitivity (OR 3.15, 95%CI 1.27-7.82), and to have a high level of self efficacy (OR 1.09, 95%CI 0.97-1.23). Exposure to campaigns and information regarding breast cancer screening, whether cancer patients are or not in around, perceived severity, perceived benefit, and perceived cost were factors that were not significantly associated with the intention to undergo mammography. Conclusion: It is necessary to develop tailored intervention strategies for women who have never undergone breast cancer screening on the basis of their demographic characteristics and factors that positively influence the intention to undergo mammography.

In general LPR(License Plate Recognition) in outdoor image is not so simple differently from in the image captured from manmade environment, because of geometric shape distortion and large illumination changes. this paper proposes three techniques for LPR in outdoor images captured from CCTV. At first, a serially connected multi-stage Adaboost LP detector is proposed, in which different complementary features are used. In the proposed detector the performance is increased by the Haar-like Adaboost LP detector consecutively connected to the MB-LBP based one in serial manner. In addition the technique is proposed that makes image processing easy by the prior determination of LP type, after correction of geometric distortion of LP image. The technique is more efficient than the processing the whole LP image without knowledge of LP type in that we can take the appropriate color to gray conversion, accurate location for separation of text/numeric character sub-images, and proper parameter selection for image processing. In the proposed technique we use DBN(Deep Belief Network) to achieve a robust character recognition against stroke loss and geometric distortion like slant due to the incomplete image processing.

Background: Any real application of Bayesian inference must acknowledge that both prior distribution and likelihood function have only been specified as more or less convenient approximations to whatever the analyzer's true belief might be. If the inferences from the Bayesian analysis are to be trusted, it is important to determine that they are robust to such variations of prior and likelihood as might also be consistent with the analyzer's stated beliefs. Materials and Methods: The robust Bayesian inference was applied to atmospheric dispersion assessment using Gaussian plume model. The scopes of contaminations were specified as the uncertainties of distribution type and parametric variability. The probabilistic distribution of model parameters was assumed to be contaminated as the symmetric unimodal and unimodal distributions. The distribution of the sector-averaged relative concentrations was then calculated by applying the contaminated priors to the model parameters. Results and Discussion: The sector-averaged concentrations for stability class were compared by applying the symmetric unimodal and unimodal priors, respectively, as the contaminated one based on the class of ${\varepsilon}$-contamination. Though ${\varepsilon}$ was assumed as 10%, the medians reflecting the symmetric unimodal priors were nearly approximated within 10% compared with ones reflecting the plausible ones. However, the medians reflecting the unimodal priors were approximated within 20% for a few downwind distances compared with ones reflecting the plausible ones. Conclusion: The robustness has been answered by estimating how the results of the Bayesian inferences are robust to reasonable variations of the plausible priors. From these robust inferences, it is reasonable to apply the symmetric unimodal priors for analyzing the robustness of the Bayesian inferences.

'I'his study investigated students' attitude toward mathematics. and how behavior/cognitive training affects level of math anxietv and level of math achievement. Subjects were all the freshmen attending Taejon Science High School, and they were given Mathematics Attitudes Scale and Attributional Style Questionnaire prior to and post training sessions. Twenty out of 84 freshmen voluntarily participated in nine sessions of training program. Participants were asked to do self-evaluation. Math achievement was measured prior to and post training. and was compared between two groups. Training program utilized behavior/cognitive approach. such as understanding one's feeling through muscle relaxation, breathing and meditation; modifying negative attributional style; imitating effective cognitive strategies for math problem solving, and so on. 'I'he result shows that students' math confidence in general was relatively low out of expectation, a nd they perceived teachers not supporting their math abilities :IS much as expected. On the other hand, students in general had strong math achievelment needs, and considered math utility very high. Sex difference was seen in the attitude toward female math abilities, to result that female students had more positive perception than male students. Female students of 'I'aejon Science High School seem free from conventional idea about female abilities including theirs. Participants' ~attitude change was compared with non-participants. and participants showed statistically significant change in their math confidence, and also in their math achievement. Participants had much higher math confidence and ~achievement than non-participants. And, they showed increased level of perceiving teachers' expectation. more realistic in needs, and more involvement in math. Math achievement was found positively related to math confidence, and participants' math achievement change was explained by their belief in math utility. Not only training program effect hut also participants' voluntary involvement and teacher\ulcorner' support of the program and participation seem to increase their math achievement. Based upon the result of study it was suggested that behavior-/cognitive training program be provided along with academic curricula for gifted students of Korea to help their emotional and psychological development enhance the efficacy of their cognitive learning.

Reflecting on own beliefs about teaching and learning, developed during "the apprenticeship of observation", is a central task for pre-service years. This case study analysed a lesson observation course which could identify, challenge pre-service teachers' folk pedagogy about classroom communications and induce to change of beliefs about teaching and learning. Our analysis shows that targeting and refuting pre-service teachers' specific belief may be an effective strategy for teacher educators to foster new teaching practice.

Data for teat number for Landrace (L), Yorkshire (Y), crossbred of Landrace and Yorkshire (LY), and crossbred of Landrace, Yorkshire and Chinese indigenous Min Pig (LYM) were analyzed using Gibbs sampling. In Bayesian inference, flat priors and some informative priors were used to examine their influence on posterior estimates. The posterior mean estimates of heritabilities with flat priors were $0.661{\pm}0.035$ for L, $0.540{\pm}0.072$ for Y, $0.789{\pm}0.074$ for LY, and $0.577{\pm}0.058$ for LYM, and they did not differ (p>0.05) from their corresponding estimates of REML. When inverse Gamma densities for variance components were used as priors with the shape parameter of 4, the posterior estimates were still corresponding (p>0.05) to REML estimates and mean estimates using Gibbs sampling with flat priors. However, when the inverse Gamma densities with the shape parameter of 10 were utilized, some posterior estimates differed (p<0.10) from REML estimates and/or from other Gibbs mean estimates. The use of moderate degree of belief was influential to the posterior estimates, especially for Y and for LY where data sizes were small. When the data size is small, REML estimates of variance components have unknown distributions. On the other hand, Bayesian approach gives exact posterior densities of variance components. However, when the data size is small and prior knowledge is lacked, researchers should be careful with even moderate priors.

This study addresses the issue of the continuity in Indonesia's party system with respect to Islam, authoritarian legacy and income, using the urban-based individual face-to-face survey data. The existing studies focus on the historical continuity of the Indonesian party system between the 1955 and 1999 democratic elections. Yet, this study deals with the continuity and discontinuity between the pre-transitional 1997 election and the transitional 1999 election. It finds that the effect of Islam is largely independent of the democratic transition: Islam-oriented voters under the authoritarian rule tend to remain in the Islamic camp even during and after the democratic transition, while most of the secular voters prior to the democratic transition continue to shun any Islamic parties during the democratization. The effect of authoritarian legacy is also found to be meaningful, even if not as sticky as Islam. Finally, the variable of income is significant. Contrary to the popular belief, the PDIP is not a party of the urban poor but the PPP is the urban poor's favorite choice. This implies the linkage between poverty and political Islam.

In this study, the relationships among students' cognitive/affective variables, cognitive conflict induced by anomalous data, and conceptual change were investigated. Tests regarding background knowledge, field dependence-independence, learning strategy, logical thinking ability, goal orientation, self-efficacy on prior concept and ability, and control belief were administered. Tests of prior conceptions, responses to anomalous data, conception, and retention of conception were also administered. There were no significant correlations of cognitive conflict induced by anomalous data with students' cognitive and affective variables. However, prior knowledge on molecular motion, field dependence-independence, and learning strategy were significantly correlated with students' conception and retention of conception. Logical thinking ability was also correlated with their conception. Multiple regression analysis indicated that learning strategy significantly predicted students' conception and retention of conception. For the affective variables, self-efficacy on ability was significantly correlated with students' conception and retention of conception, and goal orientation was correlated with their conception. Self-efficacy on ability was a significant predictor on students' conception and retention of conception, and goal orientation on their conception.

The present study examines the role of subjectively perceived factors of the attitude toward web shopping in forming an intention to use a web shopping intention. An integrative research model is presented and tested empirically. It includes the following three aspects of belief in Davis' TAM: perceived usefulness, perceived ease of use, perceived enjoyment. Specially, internet self-efficacy, or the belief in one's capabilities to organize and execute courses of Internet actions required to produce given attainments, is a potentially important factor in efforts to gain more favorable attitude toward web shopping close the digital divide that separates experienced Internet users from novices. Prior research on Internet self-efficacy has been limited to examining specific task performance and narrow behavioral domains rather than overall attainments in relation to general Internet use, and has not yielded evidence of reliability and construct validity. Survey data were collected to develop a reliable operational measure of Internet self-efficacy and to examine its construct validity. Also, much previous research has established that perceived ease of use is an important factor influencing user acceptance and usage behavior of information technologies. However, very little research has been conducted to understand how that perception forms and changes over time. The present study examines that higher internet self-efficacy is more getting favorable web shopping attitude, and web shopping intention as more as usefulness, enjoyment through the internet.

In this paper, we analyzed how 5-year-old children perceive a robot's ability to attribute mental states to oneself and to others, which shall hereafter be referred to as a robot's theory of mind (RToM). A total of 34 5-year-old children were given two typical false-belief tasks, an 'unexpected-contents task' and a 'change-of-location task', in order to evaluate whether a child's perceived RToM was connected to their own ToM. In addition, we investigated whether a child's perception of RToM was influenced by either a priori experience with robots or that child's gender. The results are as follows. Firstly, the 5- year-old preschool children universally recognized robots as beings that have a human-like mind both in 1st order and 2nd order perspectives, which indicates that children perceive robots as beings distinct from mechanical toys. Secondly, a priori child-robot interaction experience was found to have a positive influence on a child's perceived RToM. Thirdly, the gender of children did not significantly affect their perceived RToM. This study serves to add to the macroscopic results of prior research, which indicate that children perceive robots as intermediate beings between living and inanimate objects: significantly, it analyzes the children's perception of robots through the lens of theory of mind, which is one of the key elements of cognitive development. This research lays the foundations for designing effective child-robot interactions, in situations in which robots serve as peers or assistants for educational purposes.
