Objective: The purpose of the present study was to examine the changes in the body perception of young children using a short-term longitudinal design, then to investigate the factors related to their body perception. Methods: Participants were 65 preschool children and their mothers that were recruited from five institutions. An 11-month, two-time point longitudinal design was used in which children were interviewed individually to examine the changes in body perception. At the second time point, children were assessed with an additional measure to investigate self-esteem, and their mothers also reported on maternal factors and children's media experience through a questionnaire. Data were analyzed by paired t-test, independent t-test, correlations and ANOVA. Results: The results showed a significant decline of children's negative body perception over time. Children's media experience was positively correlated with negative body perception. Mothers whose children showed higher body mass index (BMI) sent more verbal messages about their child's weight reduction. In addition, children's negative body perception was positively correlated with physical self-esteem. Finally, there was a significant difference in only the physical self-esteem according to the level of children's body perception. Conclusion/Implications: The findings would suggest theoretical and practical implications to support intervention and education programs to improve the body image of young children.

Library and information service (LIS) of academic libraries plays an important role in the education and research activities of universities. Such importance of LIS facilitated much research that defines the quality factors constituting LIS and identifies the importance of them. The previous literature, however, has some limitations. The limitations arise from the interrelationship among the quality factors and the perception gap between users and providers on LIS quality factors. Despite the understanding of the interrelationship and the perception gap, LIS studies to deal with both dimesions synthetically are sparse. Therefore, this paper defines the interrelationship among LIS quality factors as a network model, then identifies the perception gap on LIS quality factors by exploiting the analytic network process. As an early stage study, this paper contributes to helping the quality improvement of acedemic LIS by considering the interrelationship among LIS quality factors and the perception gap on the LIS quality factors between LIS users and providers.

There has been increased interest in researching risk perception of radiation to implement successful risk communication, particularly given the recent worldwide nuclear policy movement regarding nuclear energy. This study aimed to investigate characteristics of risk perception among residents living near normally operating nuclear power plants in South Korea by identifying factors associated with risk perception. A survey was conducted with face-to-face interviews for 1200 residents aged 20e84 years by gender- and age-stratified random sampling. Risk perception was associated with trust perception in nuclear safety, but was not highly correlated with benefit perception for utilizing nuclear power. Relatively high risk perception was observed in women, older age groups, and residents not having experience of nuclear-related education or work. This association remained after adjusting for other factors including benefit perception, trust perception, and psychological distress. In addition to these individual characteristics, risk perception was also associated with a residential district's own unique context, indicating that a strategy of risk communication should be developed differently for residents facing nuclear-related circumstances. Given that risk perception can be changed, depending on social values such as safety culture and economic setting, further studies are required to understand the changing characteristics of radiation risk perception.

Purpose: To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability. Methods: A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$ (0.90 for total item, 0.80 to 0.88 for factors). Results: The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90. Conclusion: These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

Objectives: A great number of the elderly are not aware of having metabolic syndrome, and this pattern differs among regions of the nation. This issue is particularly important for the elderly people with chronic diseases. This study was conducted in order to identify the prevalence, predicting factors of perception and exercise behaviors of among the elderly population. Methods: Using data from the 2009 Korean Community Health Survey, we employed two-level logistic regression models to determine whether individual and community factors are associated with perception and exercise behaviors among the elderly population. Results: Results from weighted two-level logistic regression analyses indicated the individual-level factors of smoking, education level, health center education, community exercise program participation and unmet needs in men, and marital status (being separated), health center education women predicted the elders' perception. As for the community-level predictors, higher smoking and living in regions with high suicide rates significantly predicted the elders' perception and exercise behaviors of metabolic syndrome. Conclusions: These findings demonstrate that education according to stage would increase the perception and motivation toward healthier behavior particularly for the elderly with lower perception levels of metabolic syndrome.

The purpose of this study is to analyze the change of perception and to measure the degree of interaction between the lighting and the finishing materials according to preference types and the impacted factors to the spatial sensitivity of users. To do that, the this change was grasped through the experiment with Likert Scale and ANOVA of SPSS program to the simulated images. The result of this study is as following. Firstly, the personal difference in the perception of space comes from 'attention' in information processing process. The degree of the perception of users change strongly by lighting in the space expressed the 'modern natural'. Secondly, the atmosphere and the degree of perception are different in the preference of users to the spatial sensitivity and in impacted factors which are thought by users in the space sensitives. The users who prefer the 'decoration' feel the mood more strongly in the space. But the users who prefer the 'active' and 'intimacy' are opposite to that. The difference to the degree of perception is greater in the 'classic natural' than the others under the lighting turns on. Thirdly, an in-depth research which is considered of the interaction among the various factors is needed for finding the design methods for inducing the sensitivity of users in the space. And the ranking of the impacted factors should be understanded and applied to the research regarding the changes of perception in the space. Finally, this study has the limitation to be adapted to all of the situation for the space design methods. But this will be a basic data to study the design methods for users's sensitivity in the space.
