A concept of community attachment was applied to investigate the residents' support for tourism development. This study aims to identify the factors influencing conflict management and community attachment on community resident in rural tourism villages. On-site survey with self-administered questionnaires was conducted for 348 residents in the rural tourism communities. Two distinct segments were identified by factor-clustering methods: functional-affective community attachment(80.72%) and anti-community attachment(19.28%). The characteristics of community residents with each type of community attachment were determined using a Bionomial Logistic Regression model. The most important determinants of positive community attachment were the degree of tourism business involvement, sex, and education. Therefore, some government supportive programs are needed to improve community attachment for the people who are under educated and females. In addition, the functional aspects of community attachment should be considered for rural tourism development.

Recently, Topological Data Analysis (TDA) has attracted attention among various techniques for analyzing big data. Mapper algorithm, which is one of TDA techniques, is used to visualize the cluster diagram. In this study, students were clustered according to the characteristics and degree of mathematics anxiety using a mapper, and students were visualized according to mathematics anxiety. In order to do this, Mathematical Anxiety Scale (Ko & Yi, 2011) in the aspect of mathematical instability in terms of teaching - learning, ie, Nature of Mathematics, Learning Strategy, Test/Performance is used. And the number of questions that measure the anxiety of mathematics can be extracted by extracting the most relevant items among the items that measure the anxiety of mathematics.

The purpose of this research was to compare mathematically gifted students with non-gifted students in perception of learning environments, learning ability beliefs, and preference for problem-solving and task. Thirty-seven mathematically gifted students and 75 general students in middle school completed questionnaires about perceptions about mathematics. Data were analyzed by ${\chi}^2$ test and t-test. Compared with general students, mathematically gifted students estimated their talents for mathematics higher, studied mathematics more, expended more time and effort to solving difficult problems, put learning mathematics itself as their primary purpose for studying mathematics and regarded inappropriate environments as the major obstacle to mathematics study. Mathematically gifted students perceived their parents' support higher, solved problem creatively, and had higher preference for challenging tasks.

Experiments have been made to test the practical feasibility of using calcined manganese ore to desulfurize hot reducing gas. In this study, the effects of particle size of sorbents, temperature of sulfidation, flow rate and sorbent characteristics on the $H_2S$ removal efficiency of calcined manganese ore were investigated. Experimental results showed that the removal efficiency of $H_2S$ was optimum when the temperature was about 800$\circ$C and that the smaller particle size the higher the $H_2S$ removal efficiency. When the temperature was above 800$\circ$C, the reactivity of sorbent has lowered because agglomeration of sorbent increased intraparticle transport resistance, and this phenomenon was confirmed by SEM photographs. As the temperature increases, capacity for the $H_2S$ removal was increased but the equilibrium concentration of $H_2S$ was not affective.

With an assumption that the view point of a given society and time on facial attractiveness can be inferred by analyzing popular stars' faces, the cross-cultural differences in the physical measures of Korean and foreign stars were investigated. A classification model of affective facial impressions was used to obtain the physical measures of the faces and classifying them into a face-type category. The number of face images analyzed in the study were 629 in total: 258 Korean stars, and 200 foreign stars. The results show that the common characteristics found in the cross-cultural analyses of Western and Eastern stars was a babyish impression. Babyish feature was found distinctive also in western male stars, while such trend was not found in Asian male star.

It is known that gamma-band activity (GBA) and phase synchrony (GBPS) are induced by emotional visual stimuli. However, the characteristics of GBA and GBPS according to different emotional states have not been identified. The purpose of this study is to investigate the changes in gamma-band neuronal synchronization induced by positive and negative emotional visual stimuli using electroencephalograms (EEGs). Thirteen healthy male subjects have participated in the experiment. The induced spectral power in gamma-band was the highest for negative stimuli, and the lowest for neutral stimuli in 300-2,000 ms after the stimulus onset. The inter-regional phase synchronization in gamma-band was increased in 500-2,000 ms, mainly between the bilateral frontal regions and the parieto-occipital regions. Larger number of significant connections were found by negative stimuli compared to positive ones. Judging from temporal and spatial characteristics of the gamma-band activity and phase synchrony increases, the results may imply that affective visual stimuli cause stronger memory encoding than non-emotional stimuli, and this effect is more significant for negative emotional stimuli than positive ones.

This study investigated the characteristics of science imaginary pictures drawn by elementary school students and their perceptions of science imaginary drawing. To do this, $5^{th}$ graders (N=107) were selected from 1 elementary school in Gangwon province and were administered the questionnaires. Some of them were also interviewed deeply. The analyses of the results indicated that most students drew science imaginary pictures in 'land' or 'universe' of 'future' than non-science imaginary pictures. In the academic field, 'machine' was most frequently included in their pictures, and 'earth science' or 'building and traffic' was also frequently included. In addition, half of the pictures included two or more fields. Many students perceived positively the educational benefits of science imaginary drawing upon cognitive, affective, and aesthetic aspects. However, they also had several difficulties in the processes of scientific imaginary drawing such as 'difficulties in using artistic skills', 'difficulties in selecting the subject', 'difficulties in imagining', and 'difficulties in expressing my thoughts to pictures'. Educational implications of these findings are discussed.

The purpose of this study was to examine the workers＇ attitudes toward textile industry. Also the attitude was investigated how to be correlated to job stress symptoms and job performance. The data were obtained from questionnaire completed by 529 workers employed in textile or clothing companies. The SPSS package was used for data analysis which included t-test, ANOVA, mean, correlation, and factor analysis. The results showed that workers＇ attitudes toward textile industry were neither positive nor negative. The attitudes revealed to be divided into two components-cognition, affect/behavioral intention. Cognitive attitude was observed to be more positive than affective/behavioral intention attitude. The attitude differed according to personal characteristics such as sex, educational status, position, period of one＇s service, types of industry and job specifications. The attitude were correlated with job stress symptoms and job performance. The more positive the workers＇ attitudes were, the lesser job stress symptoms and the higher job performance were. As the two components of the attitudes are in the same way, the attitude toward textile industry exhibited to have higher correlation with job stress symptoms and job performance.
