The purpose of this study was to design a reliable and valid Likert-type scale to measure nuclear energy attitudes of various groups. 8 tests were applied to the construction of a 26-item long form, a 12-item middle form, and a 6-item short form of the scale. Three scales were field tested on 760 respondents representing a diverse range of subjects. The 26-item scale appeared to be reliable, content valid and construct valid. Scale reliability and homogeneity were evidenced by 0.95 coefficient alpha and positive interitem correlations ranging from 0.18 to 0.74. The results of factor analysis and known-groups comparison revealed that this scale had high validity. Reliability of the middle form and short form were evidenced by coefficient alpha of 0.92 and 0.90 respectively. The long and middle forms were strongly correlated, r-value of 0.98 and the long and short forms were also highly correlated, r-value of 0.93. Consequently, long form, middle form and short form scales were evidenced very reliable and valid in measuring nuclear energy attitudes of various groups in general. They can be used for a variety of purpose of measuring and testing nuclear energy attitude.

This paper aimed to identify the units of measuring scale in Hwangnyongsa temple planning with the published excavation survey reports. Hwangyongsa temple site was planned under Silla Capital's urban planning in 6~7C, its full size was $800{\times}800$, and main temple was $400{\times}515$ of Goguryeo's system of measurement. Main hall was located in the center of Hwangnyongsa temple site, and its location could be seen that there was the arrangement of main temple divided into 3 : 2. Building plan measuring units proved to be 351~356mm and 294~ 296mm by analyzing measured data of remains. Lecture hall and Wooden pagoda were rebuilt by using the ancestors' units of measuring scale again and Bell hall was not planned by Tang's system of measurement in middle of 8C. In this respect, it would be important to have a deliberate attitude and lay down stereotypes on research of the units of measuring scale in ancient architecture.

The purpose of this study is to investigate engineering students' attitude toward convergence and relevance with engineering education accreditation, gender, and academic year and attitude toward convergence. To be specific, fist, we examined whether the instrument for measuring attitudes toward convergence were reliable and valid for engineering students. Second, we compared levels of attitudes toward convergence in terms of engineering education accreditation, gender and academic year. Third, latent classes, which were distinguished in terms of attitudes toward convergence, were identified. Participants were 2076 engineering students. By using factor analysis and Rasch analysis, validity and reliability of instrument measuring attitudes toward convergence were confirmed. The differences in attitude toward convergence in terms of engineering education accreditation experience, gender, and academic year were examined by independent t-test and ANOVA. There were significant differences in attitude towards convergence in terms of engineering education accreditation, gender, and academic year. Students who experience engineering education accreditation program and male and high academic year have higher levels of attitude toward convergence than others. Lastly latent class analysis (LCA) was conducted to identify subgroups underlying engineering students in terms of attitude toward convergence and five latent classes were identified. In addition, the chi-square results showed that there were significant relationships between identified latent classes and engineering education accreditation, gender, and academic year. Based on these results, engineering education considering students' characteristics and diversity in attitude toward convergence were discussed.

This study focused on the development of a scale measuring the effect of consumer education. The purposes of this study were to develop a tool which could measure consumer knowledge, consumer attitudes and consumer behavior. Data were collected from 266 college students. Analysis was done using frequency, cross tabulation analysis, reliability test, principle components factor analysis, confirmatory factor analysis (Amos 5.0), and multiple regression analysis. The results from this study were as follows: 1) Nine consumer knowledge factors (23-items) were identified: consciousness of consumer education and evaluation, consumer rights and allowance management, methods of consumer education and consumer institutions, green energy and environmental consumption, essence and content of consumer education, consumer rights and consumer duty, critical consideration and consumer's damage salvation, buying minds and decision-making, independent consumers. Total variance was 58.4%. Cronbach's alpha for the nine factors ranged from .68-.79. 2) Five consumer attitude factors (26-items) were identified: green environmental consumption, consumer's role and rights, resources saving and consumer's damage salvation, consciousness of consumers, and right consumption. Total variance was 59.2%. Cronbach's alpha for the five factors ranged from .89-.94. 3) Seven consumer behavior factors (27-items) were identified: social role and rights of consumer and consumer movement, right buying and segregated garbage collection, green environmental consumption and resources saving, altruism and decision-making, allowance management and impulse buying, consumer's damage salvation, and consciousness of consumer. The total variance was 59.1%. Cronbach's alpha for the seven factors ranged from .77-.88. Finally, a scale measuring the effect of consumer education consisting of 76 items (consumer knowledge: 23 items (9 factors), consumer attitude: 26 items (5 factors), consumer behavior: 27 items (7 factors)) was constructed.

This study investigates the differences in advertisement attitude, brand attitude, and purchase intention based on advertising model and consumer product involvement. A total of 100 respondents in high involvement and 100 respondents in low involvement categories were exposed to the advertisements of a cosmetic brand using 4 different model types: celebrity endorser, expertise endorser, ordinary person as an endorser, and no endorser. The experiment was planned as $2{\times}4$ types including high/low involvement and 4 different model types (25 respondents each). After looking at an advertisement for 1 minute, respondents were asked to answer a survey measuring advertisement attitude, brand attitude, and purchase intension. The results of this study showed that 6 hypotheses were supported and there was a significant difference between the high involvement and low involvement group depending on the advertising models used as well as the advertisement that influence advertisement attitude, brand attitude, and purchase intension. High involvement consumers showed the most favorable advertisement attitude on an advertisement with an expertise endorser, but low involvement consumers showed the most favorable advertisement attitude on an advertisement with a celebrity endorser. High involvement consumers showed the most favorable brand attitude on an advertisement with an expertise endorser whereas low involvement consumers showed the most favorable brand attitude on an advertisement with a celebrity endorser. High involvement consumers showed the highest purchase intention on an advertisement with an expertise endorser whereas low involvement consumers showed no difference in purchase intention depending on advertisement models. This study shows that marketers should differentiate advertising strategies based on consumer involvement.

The spread of internet media is accelerating companies to create their own on-line brand community as one of their marketing communication tools because of the advantages in terms of cost-saving and raising their brand loyalty. The purpose of this study was to examine how the consumer's activities in the customer self-driven on line fashion brand community ultimately affect building a structural relationship between brand attitude and brand loyalty. In order to conduct this study, on-line field survey was conducted including a series of filtering questions measuring respondent's level of the community participation. SPSS 18.0 and AMOS 18.0 were used for the structure equation modeling. The result of empirical analysis showed that the attachment and the loyalty of online community have significant influences on brand attitude and brand loyalty. Also, brand attitude partly played a role as a mediating variable in the path to influence brand loyalty. Lastly, the mediating effects of brand attitude may depend on participation level of these online fashion brand community relationships.
