The aim of the present study is to investigate the complex shopping behavior of clothing consumer groups classified by the level of economic shopping orientation. Using a self-administered questionnaire, 260 respondents rated their economic shopping orientation, hedonic shopping orientation, convenient shopping orientation, store selection criteria, clothing interest, gender, age, and other demographic characteristics. A total of 248 questionnaires were analyzed. The results are as follows. First, economic consumers showed more hedonic and convenient shopping orientation than uneconomic consumers. In addition, economic consumers valued various store selection criteria. These implied that economic consumers show more complex clothing shopping behavior than uneconomic consumers. Second, as the result of comparing complex shopping behavior of economic consumers and uneconomic consumers by their characteristics such as clothing interest, gender, and age, economic consumers were found to show more complex shopping behavior than uneconomic consumers regardless of the consumer characteristics. Among them, economic consumers with higher clothing interest or in adult age particularly showed more complex shopping behavior. Furthermore, economic consumers with different consumer characteristics showed quite different aspects in their complex shopping behavior. Third, uneconomic consumers showed relatively simple, impulsive, and price-apathetic shopping behavior.

To understand the large amplitude oscillatory shear (LAOS) behavior of complex fluids, we have investigated the flow behavior of a network model in the LAOS environment. We applied the LAOS flow to the model proposed by Vaccaro and Marrucci (2000), which was originally developed to describe the system of associating telechelic polymers. The model was found to predict at least three different types of LAOS behavior; strain thinning (G' and G" decreasing), strong strain overshoot (G' and G" increasing followed by decreasing), and weak strain overshoot (G' decreasing, G" increasing followed by decreasing). The overshoot behavior in the strain sweep test, which il often observed in some complex fluid systems with little explanation, could be explained in terms of the model parameters, or in terms of the overall balance between the creation and loss rates of the network junctions, which are continually created and destroyed due to thermal and flow energy. This model does not predict strain hardening behavior because of the finitely extensible nonlinear elastic (FENE) type nonlinear effect of loss rate. However, the model predicts the LAOS behavior of most of the complex fluids observed in the experiments.he experiments.

Transporting a large table using multiple robotic agents requires at least two group behaviors of homing and herding which are to bo coordinated in a proper sequence. Existing GP methods for multi-agent learning are not practical enough to find an optimal solution in this domain. To evolve this kind of complex cooperative behavior we use a novel method called fitness switching. This method maintains a pool of basis fitness functions each of which corresponds to a primitive group behavior. The basis functions are then progressively combined into more complex fitness functions to co-evolve more complex behavior. The performance of the presented method is compared with that of two conventional methods. Experimental results show that coevolutionary fitness switching provides an effective mechanism for evolving complex emergent behavior which may not be solved by simple genetic programming.

The purpose of this study is to establish better residential environment in APT. complex. In this study, the actual conditions of exterior space, user behavior and degree of satisfaction are investigated and analyzed on the 5 high-rise story APT complex in Taegu city. The results of this study were as follow ; The size and arrangement of organizational elemnnt to exterior space in APT. complex have been regulated by law and regulations as the buildings coverage and floor space index, but housinghold and accessibility to the racility will be simultaneously considered to raise Quality of the residential environoment. The main user behavior to exterior space in APT. complex was practical activity and the user behavior pattern by week and among APT. complex were found similiarly. In the ratio of use to exterior space in APT. Complex, that of high-rise residents were lower than that of lowrise residents. In the degree of satisfaction by property of variables to exterior environment In APT. comples, physical of buildings, social - psychologic, managerial economical, physical property of exterior space were estimated positively, but properly of facility were estimated negatively. The degee of satisfaction to exterior environment in APT. complex was highly Influenced by green space, site size. As a result of ractor analysis, the four factors were drawn out from exterior environment in APT. complex. and the factors that have an effect on the degree of residents' satisfaction by factorscore were found in the order of importance as fallow ; managemental, physical, environmental, organizalional factor. Therefore, devilopment of APT. complex should be considered in a view of environmental psychology according to physical organization for used in the future. It is recommended that this problems should be necessitated to be more deeply studies in the future.

This study investigates the effects of children's social relationships and psychological characteristics on their behavior problems. Behavior problems comprise violations of norms, bullying, and deviant behavior in the cyberspace. A data set of 2949 Korean children in their 4th grade is analyzed to yield three main results. First, variables such as contact with delinquent friends, aggressiveness, stress of appearance complex, gender, and depression have significant effects on violations of norms. Children who have more delinquent friends, higher level of aggressiveness, stress of appearance complex, or depression report more violations of norms. Second, delinquent friends, stress of peer relationship, aggressiveness, stress of appearance complex, gender, parents' violent attitudes toward children, and negative self-image are turned out to be important variables predicting bullying. Children with more delinquent friends, higher level of stress, higher level of aggressiveness, or lower self-image are more likely to experience bullying. Children who perceive their parents to be violent show more bullying experience. Third, each of aggressiveness, delinquent friends, stress of appearance complex, gender, relationship with teacher, and family income has significant effect on deviant behavior in cyberspace. Children with higher level of aggressiveness, more delinquent friends, stress of appearance complex, or negative impression of teacher are more likely to deviate in cyberspace. Children from higher income families report more deviant behavior in cyberspace. Boys show more experiences in every category of behavior problems than girls.

Objectives: This study aims to determine the relationship between sedentary behavior and oral health factors in adolescents. Methods: Based on the data from the online survey on youth health behaviors, general characteristics, sedentary behavior was classified as practiced for less than 2 hours, and not practiced for more than 2 hours, and oral health was classified brush teeth after lunch, sealant, oral symptoms. The analysis methods were complex frequency analysis, complex chi-square test, and complex logistic regression analysis. Results: In case of brush teeth after lunch during the week, those who practiced it was 1,025 times higher than those who did not practice it, and in the case of oral symptoms practice was 0.915 times lower than not practice. As a result of adjusted general characteristics, for brushing teeth after lunch during the week, practice was 1,090 times higher than no practice. Conclusions: The relationship between sedentary behavior and oral health behavior and oral symptoms could be confirmed. Therefore oral health promotion programs according to sedentary behavior are needed to promote oral health for adolescents.

We consider the boundary behavior of a Hardy class holomorphic function, either on the disk D in the complex plane or on a domain in multi-dimensional complex space. Although the two theories are formally different, we postulate some unifying fearures, and we suggest some future directions for research.
