An attempt has been made to prove the so-called 'feature accumulation theory'. It is the theory describing that people tend to feel the same space with more identifiable objects much larger than that with fewer objects. Applying this theory to our cognition of spatial size, this paper made an experiment. Students were asked that if the lecture room they are sitting becomes a module (module 1), then how large are the questioned spaces in the campus. The result was striking. Through the mental image processing, they answered that the library and the architecture building looks much smaller than they actually are, and more surprisingly the basketball field much more smaller than it really is. This experiment shows that there is a strong tendency by which people regard the space much larger when there are more occupiable or behavior-causing elements in the space. In the case of basketball field, since there is nothing that can be occupied, this open space is seen as a small space for the subjects. This line of cognitive perception can be applied to the practice of urban planning and architectural planning. With the same size of given space, we can make it feel more rich and larger.

Objectives: Self perceived body image among women is drawing a lot of attention in Korea due to their unhealthy weight control behaviors. To determine the relationship between self-perceived body image and dietary behaviors among Korean women, the discrepancy between actual body size and body image perception, weight control behaviors were assessed based on age groups using the 2010 KNHANES data. Methods: A total of 1,747 subjects were selected after eliminating those of likely changing their diet recently using the 2010 KNHANES data. The subjects were divided into 3 groups, self-underweight, self-normal, and self-obese according to their perception of body image. The BMI and weight control behaviors were assessed based on age groups according to the body image perception. Results: The younger, the higher ratio of underweight, women perceived their body size as normal or overweight. Exercise and reduced food intakes were dominant among various weight control methods but unhealthy methods were dominant among self perceived overweight group. Conclusions: Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. Nutritional education should emphasize the importance of healthy weight and proper body image perception for Korean women.

This study analyzed risk perception and risk reduction behaviors of male and female college students in their twenties who purchased fashion products in internet shopping malls. It also investigated the relationship between risk perception and risk reduction behavior as well as the ways in which groups, categorized by risk perception, differed in their risk reduction behaviors. The results of this study were as follows: first, seven factors of risk perception were identified. These were product quality, shipping, product image, payment, economic feasibility, fear of other people's reactions, and size. Six types of risk reduction behavior were also identified. These were product comparison, word-of-mouth information search, price search, preference for name-brand, service comparison, and referring to experiences. Next, a correlational analysis of the factors of risk perception and those of risk reduction behavior showed several patterns. The highest positive correlation was between economic risk perception and product comparison behavior. In addition, shipping risk perception was positively correlated with service comparison behavior and product quality and product image had a positive correlation with word-of-mouth information search behavior. Third, customers of internet shopping malls could be categorized into three groups: shipping risk perception group, high risk perception group, and product quality risk perception group. The groups were shown by factor analysis to be significantly different to each other. Finally, risk reduction behavior was investigated according to the different groups of risk perception of the internet shopping malls and the results showed significant differences among groups.
