  • Service providers have introduced interactive devices such as self-service kiosks to provide convenient and efficient services to consumers. Self-service kiosks are one of the most diverse technological forms of self-service technologies that provide control and freedom to consumers as well as reduce the frustration of line-ups. This study explores the predictors of consumer resistance and continued use intention with regard to self-service kiosks. It adopts three constructs on the following variables: perceived innovation characteristics, consumer characteristics, and gamification. An online self-administered survey was conducted, and 343 users of self-service kiosk services, aged between 20 and 59, were included in the analysis. The study used the SPSS 23.0 program to perform a descriptive analysis along with, t-test, ANOVA, correlation analysis, and regression analysis. First, convenience, controllability, and gamification negatively influenced consumer resistance to self-service kiosks. Second, human alienation and sociability positively influenced consumer resistance to self-service kiosks. Third, convenience and gamification positively influenced the continued use intention with regard to self-service kiosks. Last, the risk of functionality, human alienation, and sociability negatively influenced continued use intention with regard to self-service kiosks. The results contribute to the literature because few studies have examined what drives the resistance of users and continued use intention with regard to self-service kiosks. It also provides service providers and practitioners with insights and strategies on how to overcome consumer resistance.

  • Purpose: The purpose of this study was to identify the level of psychological insulin resistance and self-care activities and to evaluate the factors affecting self-care activities in patients with type 2 diabetes mellitus undergoing insulin therapy to provide basic data for the development of educational programs. Methods: Data were collected through the interviews using a structured questionnaire from August 29 to October 20, 2017, from the patients with type 2 diabetes mellitus visiting the Diabetes Mellitus Center at H-General Hospital in J-city. The subjects were 168 patients who had been being treated via self-injection for at least three months after the start of insulin therapy. Data analyses were conducted using t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using the SAS WIN 9.2 program. Results: The mean score of psychological insulin resistance was 61.25 (range 19-95) and the mean score of self-care activities was 53.19 (range 18-90). Self-care activities were significantly different by gender (t = -2.94, p= .004), perceived health status (F= 7.00, p< .001), and hypoglycemia during the last three months (t= -2.47, p= .015). Negative correlation was observed between psychological insulin resistance and self-care activities (r= -.33, p< .001). Self-care activities were significantly predicted by psychological insulin resistance, perceived health status, gender, and hypoglycemia during the last three months, and 19.0% of the variance in self-care activities was explained (F= 9.01, p< .001). Conclusion: Psychological insulin resistance in patients undergoing insulin therapy and its effects on self-care activities identified in this study will be useful in starting and maintaining insulin therapy in the future.

  • Due to the phenomenon of aging, a new consumer segment known as the "new-silver generation" is emerging. Unlike the previous silver generation, this generation possesses significant economic power and consuming willingness, attracting attention from consumer goods companies. However, both the new-silver generation and the elderly face challenges in adopting contactless or self-service technologies such as self-order kiosks, resulting in negative reactions. Therefore, this study aims to investigate the attitude and response of the newsilver generation towards kiosks, as well as the factors influencing their resistance to such technology. By applying theoretical perspectives from the innovation resistance model, technostress theory, and the value-based model, this study identifies influencing factors for innovation resistance among the new-silver generation when using contactless technologies implemented in fast-food restaurants. The findings indicate that a lower awareness of new technologies and services corresponds to decreased adoption resistance, while a higher perceived value leads to more positive behaviors and attitudes among the new-silver generation utilizing kiosks at fast-food restaurants.

  • In order to study the effect of rubber particle size and admixture on the frost resistance of self-compacting concrete, three self-compacting concrete specimens with equal volume replacement of fine aggregate by rubber particles of different particle sizes were prepared, while conventional self-compacting concrete was made as a comparison specimen. The degradation law of rubber aggregate self-compacted concrete under freeze-thaw cycles was investigated by fast-freezing method test. The results show that the rubber aggregate has some influence on the mechanical properties and freeze-thaw durability of the self-compacting concrete. With the increase of rubber aggregate, the compressive strength of self-compacting concrete gradually decreases, and the smaller the rubber aggregate particle size is, the smaller the effect on the compressive strength of the matrix; rubber aggregate can improve the frost resistance of self-compacting concrete, and the smaller the rubber particle size is, the more obvious the effect on the improvement of the frost resistance of the matrix under the same dosage. Through the research of this paper, it is recommended to use 60~80 purpose rubber aggregate and the substitution rate of 10% is chosen as the best effect.

  • As a functional material, shape memory alloy (SMA) has attracted much attention and research effort to explore its unique properties and its applications in the past few decades. Some of its properties, in particular the electrical resistance (ER) based self-sensing property of SMA, have not been fully studied. Electrical resistance of an SMA wire varies during its phase transformation. This variation is an inherent property of the SMA wire, although it is highly nonlinear with hysteresis. The relationship between the displacement and the electrical resistance of an SMA wire is deterministic and repeatable to some degree, therefore enabling the self-sensing ability of the SMA. The potential of this self-sensing ability has not received sufficient exploration so far, and even the previous studies in literature lack generality. This paper concerns the utilization of the self-sensing property of a spring-biased Nickel-Titanium (Nitinol) SMA actuator for two applications: ER feedback position control of an SMA actuator without a position sensor, and estimation of the opening of a SMA actuated valve. The use of the self-sensing property eliminates the need for a position sensor, therefore reducing the cost and size of an SMA actuator assembly. Two experimental apparatuses are fabricated to facilitate the two proposed applications, respectively. Based on open-loop testing results, the curve fitting technique is used to represent the nonlinear relationships between the displacement and the electrical resistance of the two SMA wire actuators. Using the mathematical models of the two SMA actuators, respectively, a proportional plus derivative controller is designed for control of the SMA wire actuator using only electrical resistance feedback. Consequently, the opening of the SMA actuated valve can be estimated without using an extra sensor.
