This study attempts to understand the arrangement and spatial requisites of art pieces by materializing the visitors' path of movement in the exhibition space, as well as researching their behavior. The purpose of the research is to the guideline for planning the exhibition layout and visitors' circulation can be derived in order to correspond to the visitors' characteristic of movement and circulation-path choice. Although such guideline may have limited use, it is still significant enough to be studied. Taking three Korean art galleries as the subjects of research, this study observes the arrangement of art pieces, movement path of visitors, characteristics of the visitors' behavior and the duration time a visitor takes to view an art piece without moving around in order to understand the arrangement and spatial requisites of art pieces which correspond to the visitors' behavior. The following results have been drawn in this research and analysis; First, when there is an island type exhibition other than the ordinary on-the-wall display in the exhibition space, the visitors' choice of path changes. In short, an island type exhibition seems to be a factor that changes the visitors' path. Second, in the entrance of an exhibition space unit, most of the visitors seem to choose a path which moves counter-clockwise. Third, it is considered that well-known art pieces or art pieces with a big size shall not be displayed on the comer of the exhibition room.

Laboratory investigation reveals that rockfills exhibit significant stress-path-dependent behavior during shearing, therefore realistic prediction of deformation of rockfill structures requires suitable constitutive models to properly reproduce such behavior. This paper evaluates the capability of a strain hardening model proposed by the authors, by comparing simulation results with large-scale triaxial stress-path test results. Despite of its simplicity, the model can simulate essential aspects of the shear behavior of rockfills, including the non-linear stress-strain relationship, the stress-dependence of the stiffness, the non-linear strength behavior, and the shearing contraction and dilatancy. More importantly, the model is shown to predict the markedly different stress-strain and volumetric behavior along various loading paths with fair accuracy. All parameters required for the model can be derived entirely from the results of conventional large triaxial tests with constant confining pressures.

This paper reviews search methods of multiple reasonable paths to implement multimodal public transportation network of Seoul. Such a large scale multimodal public transportation network as Seoul, the computation time of path finding algorithm is a key and the result of path should reflect route choice behavior of public transportation passengers. Search method of alternative path is divided by removing path method and deviation path method. It analyzes previous researches based on the complexity of algorithm for large-scale network. Applying path finding algorithm in public transportation network, transfer and loop constraints must be included to be able to reflect real behavior. It constructs the generalized cost function based on the smart card data to reflect travel behavior of public transportation. To validate the availability of algorithm, experiments conducted with Seoul metropolitan public multimodal transportation network consisted with 22,109 nodes and 215,859 links by using the deviation path method, suitable for large-scale network.

This paper proposes an insect behavior-inspired routing algorithm for large-scale wireless mesh networks. The proposed algorithm is adapted from the behavior of an insect called Bombyx mori, a male silkmoth. Its unique behavior is its flying technique to find the source of pheromones. The algorithm consists of two steps: the shortest-path algorithm and the zigzag-path algorithm. First, the shortest-path algorithm is employed to transmit data. After half of the total hops, the zigzag-path algorithm, which is based on the movement of the male B. mori, is applied. In order to adapt the biological behavior to large-scale wireless mesh networks, we use a mesh topology for implementing the algorithm. Simulation results show that the total energy used and the decision time for routing of the proposed algorithm are improved under certain conditions.

The purpose of this study was to configure a model geared toward predicting factors affecting the sexual behavior of college students and the path of their influence. The standardized path coefficients of factors that might affect their sexual behavior were calculated, and the total effects of the factors were checked when the path of their influence turned out significant. As for the path of the factors affecting the sexual behavior of college students in a firsthand manner, dating exerted a firsthand influence on sexual knowledge. That had the greatest total effect on sexual knowledge, and those with dating experiences had a better sexual knowledge. Sexual knowledge exercised a firsthand influence on sexual attitude, and that had the largest total effect on sexual attitude, as the students who had a better sexual knowledge took a more positive sexual attitude. Sexual roles affected sexual attitude and sexual behavior in a firsthand way, and sexual roles had the biggest total effect on sexual behavior. Androcentric and open sexual attitudes were permissive, distorted and led to more sexual behavior.

This paper presents a new method that generates a path that has no collision with the obstacles or the characters by using the three motion parameters, and automatically creates natural motions of characters that are confined to the path. Our method consists of three parameters: the joint information parameter, the behavior information parameter, and the environment information parameter. The joint information parameters are extracted from the joint angle data of the character and this information is used when creating a path following motion by finding the relation-function of the parameters on each joint. A user can set the behavior information parameter such as velocity, status, and preference and this information is used for creating different paths, motions, and collision avoidance patterns. A user can create the virtual environment such as road and obstacle, also. The environment is stored as environment information parameters to be used later in generating a path without collision. The path is generated using Hermit-curve and each control point is set at important places.

Multi-span steel-concrete composite (SCC) bridges are very sensitive to earthquake loading. Extensive damage may occur not only in the substructures (piers), which are expected to yield, but also in the other components (e.g., deck, abutments) involved in carrying the seismic loads. Current seismic codes allow the design of regular bridges by means of linear elastic analysis based on inelastic design spectra. In bridges with superstructure transverse motion restrained at the abutments, a dual load path behavior is observed. The sequential yielding of the piers can lead to a substantial change in the stiffness distribution. Thus, force distributions and displacement demand can significantly differ from linear elastic analysis predictions. The objectives of this study are assessing the influence of piers-deck stiffness ratio and of soil-structure interaction effects on the seismic behavior of continuous SCC bridges with dual load path, and evaluating the suitability of linear elastic analysis in predicting the actual seismic behavior of these bridges. Parametric analysis results are presented and discussed for a common bridge typology. The response dependence on the parameters is studied by nonlinear multi-record incremental dynamic analysis (IDA). Comparisons are made with linear time history analysis results. The results presented suggest that simplified linear elastic analysis based on inelastic design spectra could produce very inaccurate estimates of the structural behavior of SCC bridges with dual load path.
