This study investigates the mutual effects of the physical environment and the characteristics of user's need in the children's libraries of open plan type. The children's library as a flexible space should accept user's diverse needs. Especially, Children express more positive and diverse behaviors than adults in physical environment. As the design information obtained from observation of children's behaviors are put to architectural design, the more affluent environment in which children can do positive behaviors can be made. We used two research methods of the behavior observation and interview for the children's library, and could formulate various using actions through the behavior setting observation for using library. A relational description for reading environment in this study, based on the affordance and the behavior setting theories, provided us with rich accounts for the psychological and sociocultural resources in the children's library. Consequently, the following results can be summarized. First, children need territories for family use and for place and are using library effectively through taking the two territories. Second, the zoning according to age category should be done, as behavior patterns were observed differently according to age. Third, the space composition with openness should be designed, as children need social relation and learning through imitation and observation.

Founded on a close relationship between exhibition scenarios and media, this study was conducted 1) to establish exhibition arrangement types by using three analytical indicators, such as arrangement types of exhibition, groupings of similar exhibition media, and exhibition density; and 2) to demonstrate the importance of considering the characteristics of exhibition arrangement types by using viewing behavior codes as a major analytical indicator. The following three types were investigated in this research: First, the Independent type (Type C) was found to be strongly influenced by architectural and spatial forms, especially by low exhibition density and high visual information. Also, compared with the Wall Dominant type, low number of viewing behavior codes and distribution was found even though there were high correlations among viewing behavior codes. This is assumed to be due to low exhibition density. Second, the Wall Dominant type (Type A) was found to be not influenced by architectural and spatial forms. This is because space is planned and restructured centering on the wall type showcases. At the planning stage of exhibition, it is easy to divide or combine space according to the contents and structure of exhibition scenarios. Compared with the Independent type, low correlations were found among viewing behavior codes. This is due to low participation or manipulation exhibitions. However, this implies that more active viewing behaviors can be induced if appropriate exhibition techniques and arrangement methods are used for each exhibition content. Third, the Independent Dominant type (Type B) was found to confuse visitors in selecting routes by displaying too many exhibits at a limited space in a disorderly fashion. It failed to attract visitors to the main exhibition area, where a big space is formed in the center. Visitors were found to view exhibits that are arranged near the major traffic line.

The characteristics of nonlinear seismic behavior and failure mechanism of RC space frame in railroad viaducts have been studied by the numerical analysis in time domain. The structure concerned is modeled in 3 dimensional extent and the RC frame elements consisting of fibers are employed for the columns. The fibers are characterized as RC zone and PC one to distinguish the different energy release after cracking resulted from the bond characteristic between concrete and re-bar. Due to the deviation of the mass center and the stiffness center of the entire structure the complex behavior is shown under seismic actions. The excessive shear force is concentrated on the column beside flexible one relatively, which leads to the failure of bridge concerned.

This paper studies the activities characteristics of the elderly aged 60-75 years old who can take care of themselves in the community public space, and puts forward the design principles of the community public space in the aging society. Using the methodology of experience design, through naturalistic observation, questionnaires, interviews and shadowing, the spatial and temporal characteristics of daily activities of the elderly are analyzed. In the community public space, the behavior of the elderly is essentially a social activity to get more attention and communication. This determines the needs, time, frequency and duration of activities of the elderly in community public space. In the community public space, the behavior of the elderly has the characteristics of long-term and regularity, and its behavior changes slightly with the space, the objective factors that affect the elderly are gender, age and climate. The subjective factors are lifestyle, family members and income level.

The purpose of the study is to investigate the characteristics of the elderly housing preference and spatial usage to plan floor space of the elderly housing by the respondents of the ages 50 to 79. Based on the result of the study, it is suggested that the elderly housing should be located in regards to social environmental factors rather than natural environmental ones. There are differences in preference for the space planning of housing units such as the number of rooms and bathrooms, and floor space depending on income level, so the housing should be differently planned to accept the difference of preference. On the other hand, there is not notable difference in furniture preference for each space. In the characteristics of spatial usage according to behaviors, high-income respondents demonstrate the characteristics of spatial usage in accordance with a western lifestyle. Thus, behaviors such as sleeping, watching TV, resting, reading, conversation, and receiving guests, occur using such things as beds, sofas, and dinning tables. On the other hand low-income respondents show a mixed western and traditional lifestyle. Thus many behaviors are done on the floor of bedroom and livingroom in addition to using furniture such as a sofa and chairs. Therefore, the way of spatial usage has to be reflected in the floor space planning. At least floor space of the provided rooms should be planned to accommodate the behavior of the elderly even though all of the rooms preferred can not be provided.

For human-robot interaction, a robot should recognize the meaning of human behavior. In the case of static behavior such as face expression and sign language, the information contained in a single image is sufficient to deliver the meaning to the robot. In the case of dynamic behavior such as gestures, however, the information of sequential images is required. This paper proposes behavior classification by using fuzzy classifier to deliver the meaning of dynamic behavior to the robot. The proposed method extracts feature points from input images by a skeleton model, generates a vector space from a differential image of the extracted feature points, and uses this information as the learning data for fuzzy classifier. Finally, we show the effectiveness and the feasibility of the proposed method through experiments.

In this study, the pull-out behavior of a tunnel-type anchorage for suspension bridges was investigated using experimental tests and image processing analyses. The study focused on evaluating the initial failure behavior and failure mode of the tunnel-type anchorage. In order to evaluate the failure mode of tunnel-type anchorage, a series of scaled model tests were conducted based on the prototype anchorage of the Ulsan Grand Bridge. In the model tests, the anchorage body and surrounding rocks were fabricated using a gypsum mixture. The pull-out behavior was investigated under plane strain conditions. The results of the model tests demonstrate that the tunnel-type anchorage underwent a wedge-shaped failure. In addition, the failure mode changed according to the differences in the physical properties of the surrounding rock and the anchorage body and the size of the anchor plate. The size of the anchor plate was found to be an important parameter that determines the failure mode. However, the difference in physical properties between the surrounding rock and the anchorage body did not affect its size. In addition, this study analyzed the initial failure behavior of the tunnel-type anchorage through image analysis and confirmed that the failure was sequentially transferred from the inside of the tunnel to the surrounding rock according to the image analysis. The reasonable failure mode for the design of the tunnel-type anchorage should be wedge-type rather than pull-out type.

This study investigated whether there was a difference in off-line consumption behavior on and off-line. Online surveys were conducted on 218 people aged 20 to 59 who live in the country actively using Instagram, and the results of analysis through technical statistical analysis, logistic regression analysis, and linear regression analysis are as follows. There are some differences in the consumption items and expenditures of showing consumption behavior on Instagram and showing consumption in real space. In addition, there were different factors influencing the behavior of showing off in Instagram and the factors affecting the showing of consumption in real space. Age, education, and narcissism have an effect on show off behavior in Instagram, whereas age, materialism, and narcissism have been identified as factors influencing in real space. Whether on Instagram or in the real space, the positive emotions felt by consumers after showing off consumption had a statistically significant effect on consumer happiness. This study has significance in that it has empirically verified the difference between Instagram and actual consumption behaviors, and sought the direction of healthy consumption behaviors for consumer happiness.

The existence of initial imperfections in manufacturing or assembly of double-layer space structures having hundreds or thousands of members is inevitable. Many of the imperfections, such as the initial curvature of the members and residual stresses in members, are all random in nature. In this paper, the probabilistic effect of initial curvature imperfections in the load bearing capacity of double-layer grid space structures with different types of supports have been investigated. First, for the initial curvature imperfection of each member, a random number is generated from a gamma distribution. Then, by employing the same probabilistic model, the imperfections are randomly distributed amongst the members of the structure. Afterwards, the collapse behavior and the ultimate bearing capacity of the structure are determined by using nonlinear push down analysis and this procedure is frequently repeated. Ultimately, based on the maximum values of bearing capacity acquired from the analysis of different samples, structure's reliability is obtained by using Monte Carlo simulation method. The results show the sensitivity of the collapse behavior of double-layer grid space structures to the random distribution of initial imperfections and supports type.
