Laundry has traditionally been regarded as one of the most demanding household chores, but the introduction of smart washing machines is changing this perception. Although smart washing machines have been on the market for several years and consumers' perceptions of washing machines have changed, little is known about consumers' perceptions of smart washing machines. The purpose of this study is to determine what users expect from smart washing machines. We conducted two focus group interviews with sixteen participants who had used smart home appliances to acquire qualitative data. Stimuli created by the interviewees were applied in the focus group interviews to collect more insightful data. We analyzed the data using the three-step method and QSR NVivo. Analysis revealed ten categories of predictive expectations, including seven utilitarian attributes (i.e., smart functionality, smart user interface, reliability, controllability, interactivity, functional value, and economic value) and three hedonic attributes (i.e., fashionable value, psychological value, and social value). The results of this study have implications for the development of smart washing machines that would satisfy consumers by taking user expectations into account.

Traditional financial approaches have been failed to satisfy the firms in evaluating the payoffs from information technology(IT) investment. This research developed a processed-oriented model to evaluate the impacts of IT on the primary business activities within the value chain. The model proposed in this research incorporates corporate goals for IT and strategic alignment as key measurements of IT impacts. We found that corporate goals for IT can be classified into one of four categories: unfocused, operations focus, market focus, and dual focus(operations and market focus), using survey data collected from 137 corporate executives in Korea. The empirical analysis confirms that corporate goals for IT are useful indicators of impacts from IT in that executives in firms with more focused goals for IT perceive higher payoffs from IT in the value chain. We also found that strategic alignment contributes to higher perceived levels of IT payoffs.

Regulatory fit occurs when the way people act accords with their goal orientation the activity. When there is regulatory fit, to pursue a goal feels light and also increases the value of what a person is doing-value from fit. Value from fit can be transferred to other value experiences such as monetary value. Present research proposes that regulatory fit occurs when the domain in which a decision or an evaluation is made sustains the decision maker's chronic goal orientation, and this regulatory fit affects the value that he or she assigns to the object. In Experiment 1, participants with chronic promotion or prevention focus evaluated their preference and purchase intention on 14 design products including positive and negative emotional valences. Results showed that evaluations on the product design (promotion domain) were more extreme under promotion than prevention, F(1, 95) 4.87, p < .05. In Experiment 2 with 16 moral scenarios including prescriptive and proscriptive morality, prevention-focus individuals evaluated immoral behaviors as more immoral than promotion-focus individuals only in the proscriptive scenarios (prevention domain), F(1, 139) = 4.14, p < .05. In prescriptive scenarios, regulatory fit effect was not found. Findings from both experiments suggest that regulatory fit occurs when the domain of an issue that people engage in sustains their goal orientation.

In this paper, our focus is on exploring value sharing problems related to a transcendental entire function f and its associated differential-difference polynomials. We aim to establish some results which are related to differential-difference counterpart of the Brück conjecture.

This paper presents a SFF(shape from focus) algorithm using a new focus measure based on higher order statistics for the exact depth estimation. Since conventional SFF-based 3D depth reconstruction algorithms used SML(sum of modified Laplacian) as the focus measure, their performance is strongly depended on the image characteristics. These are efficient only for the rich texture and well focused images. Therefore, this paper adopts a new focus measure using HOS(higher order statistics), in order to extract the focus value for relatively poor texture and focused images. The initial best focus area map is generated by the measure. Thereafter, the area refinement, thinning, and corner detection methods are successively applied for the extraction of the locally best focus points. Finally, a 3D model from the carefully selected points is reconstructed by Delaunay triangulation.

This paper proposes an auto-focusing method for production of compact camera module (CCM). The CCM test handlers are mainly used in the final CCM production stage to test and adjust the lens focus of CCMs. To improve the productivity of CCM test handlers, we propose the auto-focusing method adjusting the lens focus efficiently. The max-min-difference (MMD) method is newly developed to compute the focus value efficiently, and two-stage searching method is also developed to find the best focus position quickly. Experimental results are presented to verify the usefulness of proposed method.

In this paper, a new autofocusing technique which is resistive to noise generated by the CCD of video cameras is proposed. In the proposed scheme, the frequency selective weighted median (FSWM) filter is utilized to estimate the degree of focus and the fast hill-climbing search (HCS) strategy is exploited to determine the best focused image. Since the FSWM filter can not only extract high frequency components from the image, but also eliminate impulsive noise, the proposed autofocusing method employing the FSWM criterion function can estimate the degree of focus precisely. Furthermore, the proposed real-time HCS algorithm enables the video camera to continuously focus on dynamic images. Experimental results demonstrate that the proposed technique outperforms existing techniques by enhancing the accuracy of the focus value of the video camera without the influence of noise.

In this paper, we propose a framework for multi-focus image fusion called PATN. In our approach, by aggregating deep features extracted based on the U-type Transformer mechanism and shallow features extracted using the PSA module, we make PATN feed both long-range image texture information and focus on local detail information of the image. Meanwhile, the edge-preserving information value of the fused image is enhanced using a dense residual block containing the Sobel gradient operator, and three loss functions are introduced to retain more source image texture information. PATN is compared with 17 more advanced MFIF methods on three datasets to verify the effectiveness and robustness of PATN.

The coffee industry has grown very fast ever since international coffee brands were launched in the 1990's. Recently, consumers have begun to focus on coffee produced ethically. This phenomenon is due to ethical-consumption consciousness, which consists of three factors, emotional value, social value and function value. Most studies on this topic have focused on consumers who purchase fair-trade coffee. Thus, this study is novel in its focus on baristas who sell fairtrade coffee in their shops as well as differences from former studies. The three factors of ethical-consumption consciousness of baristas affected the sale of fair-trade coffee, except for the function value. Therefore, the sale of fair-trade coffee could be influenced by ethical-consumption consciousness of baristas. This study shows that education of baristas can promote the sale of fair-trade coffee. However, there are limitations as it only researched coffee brands ranked in the top 5, so further studies will be required in the future.
