Purpose: This study aimed at exploring the product choice tendency differences between the consciousness and unconsciousness of goal orientation when product attributes is perceived to be compatible with the goal orientation. Research design, data and methodology: Empirical study used a 2 (goal conscious vs. unconscious) × 3 (hedonic vs. performance vs. reliability attribute) between-subjects design and one control group. To verify hypotheses, χ²-test was conducted to 320 questionnaire data answered by undergraduate students of Jiangxi Normal University in China. Results: First, consumers under unconscious condition showed a higher product choice consistency based on compatibility between hedonic (performance) attribute of the product and their hedonic (performance) promotion goal-orientation than those under the conscious condition. Second, product choice effects of compatibility between reliability attribute of the product and prevention goal orientation were not significantly different between consumers' consciousness and unconsciousness of their prevention goal orientation. Conclusions: Marketers of 'under dog' should try to develop and deliver the product attributes different from the attributes of 'top dog.' And the 'top dog' marketers should help their customers to avoid the conflicts by developing the environment of inducing their goal orientation unconsciously. Brand marketers should always pay attention to the reliability attributes concerned with the prevention goal orientation.

We examined how emotional background stimuli influence focused attention in a flanker task. An IAPS picture was presented for 1,000ms in advance, then a target and two flanker letters were presented against the IAPS picture for 200ms(Experiment 1). The flanking stimuli were simultaneously presented on the left and right sides of the target stimulus with distance of $0.5^{\circ}C$, $1^{\circ}C$, or $1.5^{\circ}C$ visual angle. We investigated the flanker compatibility effect that identification of target would be faster when they were flanked by identical(compatible) stimuli than when they were flanked by different(incompatible) stimuli. Results of Experiment 1 revealed that the flanker compatibility effect depended not only on the distance of flankers but also on the valence of a background IAPS pictures. Positive and neutral pictures showed distance effect that the flanker compatibility effect was decreased as the farther the distance was, while negative pictures showed no di stance effect. Positive and neutral pictures showed compatibility effects at all distance conditions, but negative pictures didn't showed compatibility effect at $1.5^{\circ}C$ distance condition. In Experiment 2, the SOA(Stimulus Onset Asynchrony) between the picture and the stimuli of flanker task was manipulated. The flanking stimuli were presented simultaneously on the left and right sides of the target stimulus with a distance of either $0.5^{\circ}C$ or $1.5^{\circ}C$ visual angle. The results of Experiment 2 showed that flanker compatibility effect depends on SOA. At long SOA(2800ms), negative pictures showed no distance effect, but positive or neutral pictures did. All valence conditions of background pictures showed compatibility effects at $0.5^{\circ}C$ distance condition, but didn't showed compatibility effect at $1.5^{\circ}C$ distance condition. At short SOA(100ms), all valence conditions of background pictures showed distance effect, and showed compatibility effects with the exception of negative background pictures at $1.5^{\circ}C$ distance condition. These findings suggest that the scope of visual attention becomes narrower when viewing negative emotional stimuli and becomes broadened when viewing positive emotional stimuli. The narrowed scope of attention in negative emotion lasts longer, while the broaden scope of attention in positive emotion lasts shorter.

In the present paper, a behavioral model is proposed for study of the individual contributions to shear capacity in shear-critical reinforced concrete members. On the basis of the relationship between shear and bending moment (V = dM/dx) in beams subjected to combined shear and moment loads, the shear resistant mechanism is explicitly decoupled into the base components-beam action and arch action. Then the overall behavior of a beam is explained in terms of the combination of these two base components. The gross compatibility condition between the deformations associated with the two actions is formulated utilizing the truss idealization together with some approximations. From this compatibility condition, the ratio of the shear contribution by the tied arch action is determined. The performance of the model is examined by a comparison with the experimental data in literatures. The results show that the proposed model can explain beam shear behavior in consistent way with clear physical significance.

The stress intensity factor has been calculated for the cracked plate subjected to remote normal stress and reinforced with a plate by symmetric spot welding. The solution was based on displacement compatibility condition between the cracked sheet and the reinforcement plate. It is shown that the results from the derived equation for stress intensity factor were agreed with previous solutions. The reinforcement effect gets better as a joining spot is closer to the crack tip and the other joining spots become nearer to the crack surface.

This paper presents a model for evaluating the contribution by arch action to shear resistance in shear-critical RC beams. Based on the relationship between shear and bending moment in beams subjected to combined shear and bending, The behavior of a beam is explicitly divided into two base components of the flexural action and the tied arch action. The compatibility condition of the shear deformation that deviates from Bernoulli bending plane is formulated utilizing the smeared truss idealization with an inclined compression chord. From this shear compatibility condition in a beam, the shear contribution by the arch action is numerically decoupled.

The aim of this study is to collect driver's psychophysiological signal under various road condition and to select and quantify psychophysiological variables for diagnosis of road-driver compatibility. A 4x4 vehicle with measuring devices was developed to collect driver's psychophysiological signal and collected driver's psychophysiological signal under various road conditions. The collected data were analyzed by the temporal pattern of signal overtime. Thirteen bio-signals with consistent pattern were selected and quantified in terms of slope and amplitude of the signal. These quantified values could be used as a part of tool to diagnose the road-driver compatibility.

This paper presents a model for evaluating the contribution by arch action to shear resistance in shear-critical reinforced concrete beams. Based on the relationship between shear and bending moment in beams subjected to combined shear and bending, the behavior of a beam is explicitly divided into two base components of the flexural action and the tied arch action. The compatibility condition of the shear deformation that deviates from Bernoulli bending plane is formulated utilizing the smeared truss idealization with an inclined compression chord. The Modified Compression Filed Theory is employed to calculate the shear deformation of the web, and the relative axial displacements of the compression and the tension chord by the shear flow are also calculated. From this shear compatibility condition in a beam, the shear contribution by the arch action is numerically decoupled. Then the validity of the model is examined by applying the model to some selected test beams in literatures. The results may confirm the rationale of the proposed behavioral model.

Objective: This paper targets a framework of a hand gesture based interface design. Background: While a modeling of contact-based interfaces has focused on users' ergonomic interface designs and real-time technologies, an implementation of a contactless interface needs error-free classifications as an essential prior condition. These trends made many research studies concentrate on the designs of feature vectors, learning models and their tests. Even though there have been remarkable advances in this field, the ignorance of ergonomics and users' cognitions result in several problems including a user's uneasy behaviors. Method: In order to incorporate compatibilities considering users' comfortable behaviors and device's classification abilities simultaneously, classification-oriented gestures are extracted using the suggested human-hand model and closed-loop classification procedures. Out of the extracted gestures, the compatibility-oriented gestures are acquired though human's ergonomic and cognitive experiments. Then, the obtained hand gestures are converted into a series of hand behaviors - Handycon - which is mapped into several functions in a mobile device. Results: This Handycon model guarantees users' easy behavior and helps fast understandings as well as the high classification rate. Conclusion and Application: The suggested framework contributes to develop a hand gesture-based contactless interface model considering compatibilities between human and device. The suggested procedures can be applied effectively into other contactless interface designs.

In simply supported concrete beams with concentrated load, there is arch action that the internal lever arm length varies through shear span. Recently shear analysis model considering this effect has been developed, but the analysis algorithm is so complicated. Moreover, the variation of internal lever arm length is not considered on the shear compatibility condition. In this study, the shear analysis model is developed more simply and the variation of internal lever arm length is considered on the shear compatibility condition. From these modifications, an actual shear behavior of RC beams subjected to concentrated load could be expected from the results of the proposed analysis model.

This paper presents a closing method for a cable-stayed bridge erected by the free cantilever method to produce the initial equilibrium configuration at the final construction stage. To realize the initial equilibrium condition in cable-stayed bridge by the cantilever method, compatibility conditions for vertical displacements, rotational angles, and axial displacements at the closing section of both side girders should be satisfied. In this paper, it was shown that it can be accomplished by using some applicable loads during construction such as the pull-up force of the derrick crane, some cable tension forces, and jacking force at the pylon. The proposed method was applied to a construction stage analysis of a sample bridge to demonstrate its validity, and it was acknowledged that the tower was considerably affected by the compatibility condition for axial displacement in the closing step.
