Purpose: This descriptive study was designed to investigative BMI(body mass index) and health behaviors in college students. Method: The subjects of this study consisted of 189 college women and 125 college men. Data were collected using self-report questionnaires from April 1 to April 10, 2005. Data were analyzed by the SPSS /pc 10.0 statistical program using frequency, t-test, $x^2$-test. Result: College women perceived themselves as more obese than indicated their BMI, and the most effective weight control factor was their response to images of people presented in the media. In general college men present more salubrious behavior than college women. Conclusion: The results suggest that health care providers need to educate female students about heathy behavior as well as the normal weight in BMI.

For action selection as well as learning, simple associations between stimulus and response have been employed in most of literatures. But, for a successful task accomplishment, it is required that an animat can learn and express behavioral sequences. In this paper, we propose a novel action-selection-mechanism to deal with sequential behaviors. For this, we define behavioral motivation as a primitive node for action selection, and then hierarchically construct a network with behavioral motivations. The vertical path of the network represents behavioral sequences. Here, such a tree for our proposed ASM can be newly generated and/or updated, whenever a new sequential behaviors is learned. To show the validity of our proposed ASM, three 2-D grid world simulations will be illustrated.

With science and technology getting more and more advanced, the scope of digital product is expanding and the new products continuously are introduced on the market. On the basis of consumers' attachment to products, we investigated the consumers' behaviors towards the product when a digital product is extended. As a result of an empirical analysis, it turned out that a consumer tended to have higher trust and a positive emotion about relevant goods if he or she had a strong attachment to digital products. However, even though one had a strong attachment to digital products, the emotion about the corresponding brands did not necessarily appeared to be positive. In the event that a brand of digital products was extended to other new products, only the trust in the brand exerted significant influence on the consumers' behaviors towards the extended products. Finally, this study suggests some theoretical and managerial implications for effective strategies in response to customers' attachment to digital product.

Fast Fourier Transformation(FFT) is one of the most useful way to analyze response signal for the purpose of grasping the dynamic characteristics of system. Vibration test using impact hammer is typical and simple experimental method widely used for catching hold of dynamic peculiar characters and modal behaviors of system. In this thesis, impact testing module for NI-PXI equipment is developed. The analyzing and visualizing module are developed with LabVIEW tool. A user can see quickly and easily modal shape of system after analyzing acquired data. This developed module will be expected to build up more convenient and serviceable measurement system.

Metabotropic glutamate receptor (mGluR)-dependent long-term depression (LTD), a type of synaptic plasticity, is characterized by a reduction in the synaptic response, mainly at the excitatory synapses of the neurons. The hippocampus and the cerebellum have been the most extensively studied regions in mGluR-dependent LTD, and Group 1 mGluR has been reported to be mainly involved in this synaptic LTD at excitatory synapses. However, mGluR-dependent LTD in other brain regions may be involved in the specific behaviors or diseases. In this paper, we focus on five cortical regions and review the literature that implicates their contribution to the pathogenesis of several behaviors and specific conditions associated with mGluR-dependent LTD.

Burnout is a severe psychological and physical syndrome that occurs in response to prolonged stress at work. It brings enormous costs to both organizations and individuals because it negatively impacts employees' job attitudes and leads to undesirable behaviors. The purpose of this study was to examine the negative effects of job burnout on the organizational commitment and organizational citizenship behavior of social worker. Organizational citizenship behaviors are efforts by employees above and beyond what is expected. For the research, burnout was consisted of emotional exhaustion(EE), depersonalization(PA) and diminished personal accomplishment(DP) by Maslach and Jackson's MBI. This study analyzed 342 social workers in private social welfare organizations by survey. The results of this study were summarized as follows: Social Workers had negative correlation to burnout on the organizational commitment and organizational citizenship behavior. Especially, EE, PA and DP had a negative effect on the organizational commitment; PA and DP had a negative effect on the organizational citizenship behavior. This study finally discussed theoretical implications for future study and practical implications for burnout strategies on the results.

Aeroelastic wind tunnel experiments were conducted for conventional and tapered super-tall building models to investigate the effect of taper on fundamental aeroelastic behaviors in various incident flows. Three incident flows were simulated: a turbulent boundary-layer flow representing urban area; a low-turbulent flow; and a grid-generated flow. Results were summarized focusing on the effect of taper and the effect of incident flows. The suppression of responses by introducing taper was profound in the low-turbulence flow and boundary-layer flow, but in the grid-generated flow, the response becomes larger than that of the square model when the wind is applied normal to the surface. The effects of taper and incident flows were clearly shown on the normalized responses, power spectra, stability diagrams and probability functions.

The purpose of this study were to investigate the differences of shopping value, promotional affects and product characteristics between buyers and non-buyers, and to examine the most influenced variable on purchasing behaviors of fashion products in CATV home-shopping. We collected data from 595 consumers related to CATV home-shopping in Busan. Data were analyzed by factor analysis, t-test, ${\chi}^2$-test and discriminant analysis. Results showed that there are significant differences between buyers and non-buyers of shopping value demographic characteristics, promotional affects and product characteristics. Especially, shopping value perceived by consumers(e.g., practical value and hedonic value) and product characteristics(e.g., response of others) discriminated whether consumers purchased the fashion products of CATV home-shopping or not. We discussed the implications of results to encourage the purchasing behavior of fashion products in CATV home-shopping.

Graphene and graphene derivatives have attracted enormous attention from various research fields for applications in electronic devices, transparent electrodes, biosensors, drug delivery system and surface coatings. In the viewpoint of chemist, the chemical structure of graphene derivatives seems intriguing but detailed structures are being revealed only recently while engineering approaches for various applications are being executed very actively. In addition, cytotoxicity and mammalian cellular responses to graphene have not thoroughly investigated yet in spite of the importance in bio-applications and environment. In this talk, I'll introduce recent studies which report cytotoxicity and behaviors of mammalian cells when the cells are exposed to graphene (as well as some bio-applications of graphene), especially to get closer to answers to these questions, "how we understand and how/why we use graphene in biotechnology".

Long-term properties of concrete affect structures in many respects, not excepting dynamic behaviors. This paper investigates the influence of concrete creep on the dynamic behaviors of concrete filled steel tube (CFT) arch bridges, by means of combining the analytical method for the creep of axially compressed CFT members, which is based on Model B3 for concrete creep, with the finite element model of CFT arch bridges. By this approach, the changes of the stress and strain of each element in the bridge with time can be obtained and then transformed into damping and stiffness matrices in the dynamic equation involved in the finite element model at different times. A numerical example of a long-span half-through CFT arch bridge shows that creep influences the natural vibration characteristics and seismic responses of the bridge considerably, especially in the early age. In addition, parameter analysis demonstrates that concrete composition, compressive strength and steel ratio have an obvious effect on the seismic response of the CFT arch bridge.
