In order to derive the success factors of a Mega-scale national project, this study conducted a questionnaire survey on experts participating in the Yongsan National Park development program to obtain critical success factors in the program definition phase. AHP analysis was performed for each category through a survey of experts participating in the definition phase of the Yongsan park development program to derive relative importance. The categories were classified into program strategy, process, and people, and the importance between categories was people, strategy, and process in that order. In addition, as for the 27 critical success factors in the program definition phase, the program manager's competency and leadership, environmental and cultural property survey planning, program management plan preparation, operation and maintenance philosophy, and integrated program office showed high priorities. Therefore, in promoting the Yongsan Park development program, we propose a strategy for selecting and focusing on the critical success factors with high priorities in the program definition phase proposed in this study.

The purpose of this research is to know what factors have impacts on their risk perception and attitude in risk communications. This research shows the research findings that the determinant factors of risk perception are the possibility to control the risk, benefits of recognition, the specialty of risk management, and the usefulness of information about the risk. And also the results have shown that the determinant factors of risk attitudes are the possibility to control the risk, the understanding of science and technology, the familiarity with the risk, the usefulness information about the risk, the accuracy of information, and the initiative in the protection of citizens from the risk. As the results have indicated, common determinant factors are the usefulness of information about the risk and the possibility to control the risk. Both of them that affect risk perception and attitudes on electromagnetic waves are important factors in risk communication research. Therefore this study shows that what factors suppose to be considered important in risk communication process about risk of electromagnetic waves.

Categorization is very important for product design. Consumer's emotion become different according to a type of categorization, so design concept and design elements must be combined differently with difference of the emotion. Specially, categorization process is necessary if nowadays product line is enlarged, and a product differentiation is not clear. That is, designers decide on correct categories and a design concept based on similarity of emotion and have to provide to consumer-oriented design. The purpose of this study is to provide a design direction for Korean traditional sauce products after extracting consumers' sensitivity from the whole image of Korean traditional sauce and each images of the sauces-korean hot pepper paste, soybean paste, fermented soybeans paste, SsamJang, and soy sauce- and deciding categories of the each sauces based on the extracted sensitivities' similarity. In the result of this study, we knew that Korean traditional sauces didn't differentiate from consumers' preference images. In our empirical research, the research - emotional image survey on sauces - have conclusion that emotional image of "well-being", "tasty" have positive influence, but emotional image of "messy and dirty", "smelly" have negative influence. Therefore, we suggest that positive emotional images like "tasty" should be emphasized, but negative emotional images like "messy" should be eliminated for design and marketing strategy of Korean traditional sauces. This research will suggest the guideline for product design with respect to academic aspects and working-level aspects.

Analysis of the syntactic structure of the modern Chinese adverbs for time 'Cengjing (曾經)' and 'Yijing (已經)' was performed to examine the tenses and aspects of the terms. The corresponding Korean words were examined and the terms in both languages were compared. The syntactic structures used in China and South Korea were found to be different. We hope the study of the Chinese language will help Korean students. 'Cengjing (曾經)' specific projects with 'aspect' of, 'Past experience aspect', 'Past continuous aspect', 'Past continuous aspect' in the past tense. [ED: unclear, please reword] These correspond to '_었 (았)_', '_었었_' in the Korean language. 'Yijing (已經)' has 'finished phase' of concrete projects, 'Past experience aspect', 'Past continuous aspect', also has a specific project tense, the 'past tense', 'present tense', 'future tense', and so tense. [ED: unclear, please reword] Adjectives can also be modified with a 'change of status'. These correspond to '_었 (았)_', '_고_', '_었었_', '곧' etc. in Korean. 'Cengjing (曾經)' and the dynamic auxiliary 'Guo (過)' were compared to determine whether they have the aspect and tense features. However, 'Guo (過)' can only modify the predicate verb, so it possesses only aspect characteristics. 'Cengjing (曾經)' modifies the range more widely. 'Yijing (已經)' may be modified by the adverb 'Zai (在)' whereas 'Cengjing (曾經)' may not. Additionally, 'Yijing (已經)' can be modified by predicate adjectives and noun predicates, while 'Cengjing (曾經)' cannot.

This study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Cheongju-City. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students for a week from December 19th 2011. The survey result showed that 77 male students and 169 female students(total 246 students) answered 'yes' to the question 'Have you ever felt fear when you visited a dentist?' among 475 students who had visited a dentist in the past. The distribution of responses in each category of fear was examined by frequency analysis. The study results showed significant difference in the item of 'causing irritation during the dental treatments' between male students and female students (p<0.05). Converting the level of fear into scores after marking the answers, the score of male students was 52.0 points and the score of female students was 58.53 showing the score of female students was significantly higher in statistics. Moreover, the fear score of female students for the category 'causing irritation during the dental treatments' was also significantly higher in statistics(p<0.05). Therefore, these results should be reflected to the dental care environments in order for the adolescent to reduce the dental anxiety and fear.

In general, the methods of the analysis of variance(ANOVA) for the continuous data and the chi-square test for the discrete data are used for statistical analysis of the effect and the association. In multidimensional data, analysis of hierarchical structure is required and statistical linear model is adopted. The structure of the linear model requires the normality of the data. A multidimensional categorical data analysis methods are used for causal relations, interactions, and correlation analysis. In this paper, Bayesian network model using probability distribution is proposed to reduce analysis procedure and analyze interactions and causal relationships in categorical data analysis.

The purpose of this study was to investigate high school students' preference for science(PS) and its causal factors in terms of gender difference, and to suggest the way to improve students' preference for science. A questionnaire to evaluate the PS of high school students and its causal factors was specially designed by researchers. It was administered to 429 boys and 449 girls in eight high schools. The average score of the PS was 3.16 of 5.00 which was not high, but the PS scores of students who had wanted to be engaged in jobs related to science or medical field, were higher than the students who would be in other fields. There was no statistically significant difference between the boys' PS scores and girls', but the average scores of causal factors were higher in boys than in girls. Path analysis using a structural equation model was indicated that the pathways showing how causal factors made effects on each category of the boys' PS were simpler than those of girls. Particularly, while educational factors made indirect effects on three categories of the boys' PS, they did direct effects as well as indirect effect on the girls' PS. This means that the girls' PS is possible to be improved by applying the educational programs specially developed for girls.

We studied aspects of secondary school science teachers in the Chonbuk province concerning their science-related attitudes using the several measuring tools. We applied the multiple comparison to twelve factors at the science teachers 'backgrounds and analyzed the discrepancy in group levels. Science teachers feel half-hearted for the attitudes related to science teachers show a high correlation between the attitudes toward science and the scientific attitudes. We examined the tendency to the science-related attitudes of science teachers having various backgrounds within 5 percent differences of P-value. The contented teachers for their occupations marked higher than the other teachers in the tendency to the science-related attitudes, and the attitude-score of the science teachers graduated from regular colleges also marked higher than the teachers from the training institutes or the different majors. We have investigated the teachers just in Chonbuk province, but we should recognize that the scores in both the perception and the teachers are not improved comparing with the before-studies of Lee(1985), Park(1993), etc. As a result, the development of measuring tools which teachers can examine themselves as their features is needed and the educational systems to specialize the science education should be improved through the various programs for teachers' training courses.
