Background Our usage of technology and the continuous adoption of technological innovations has implications for our lives that go beyond traditional marketing questions such as product quality, customer satisfaction, and customer loyalty. The psychological consequences of new technology affect our lives and our well-being as individuals. A current technological advancement is the ongoing development of automated driving capabilities. The recent advances have led to the diffusion of semi-autonomous driving systems, such as Teslas autopilot or Daimlers DISTRONIC PLUS. These commercially available technologies correspond to the second level of SAE international’s J3016 standard for automated driving, which ranges from 0 (“No Automation”) to 5 (“Full Automation”, no human needed). SAE level 2 (“Partial Automation”) is defined as “the driving mode-specific execution by one or more driver assistance systems of both steering and acceleration/deceleration using information about the driving environment and with the expectation that the human driver performs all remaining aspects of the dynamic driving.” (SEA On-Road Automated Driving (ORAD) committee, 2014). First of all, qualities of mobility such as safety and comfort influence well-being directly and autonomous driving has a potential impact on these qualities. Furthermore, advances in autonomous driving have particularly social but also ecological and economic benefits. On the one hand, social benefits result from increased social participation by improving mobility of the non-driving, elderly or people with travel-restrictive medical conditions (Harper, Hendrickson, Mangones, & Samaras, 2016; Wadud, MacKenzie, & Leiby, 2016). On the other hand, social benefits result from increasing road safety, less congestions as well as from a reduced number of accidents (Fagnant & Kockelman, 2015). Individual social or personal benefits such as improved safety and comfort or reduced stress levels are also widely perceived by potential users (Bansal, Kockelman, & Singh, 2016; Karlsson & Pettersson, 2015). Additionally, ecological benefits can be realized due to more efficient driving of vehicles and a smoother traffic flow (Wadud et al., 2016). Economic benefits are mainly a result of decreased travel times and of the fact that at high automation levels driving time could be used more productively. Accordingly, this research tends to answer the following research questions: • How does automated driving impact consumers’ well-being? • What qualities of mobility (e.g. safety) mediate the impact of automated driving on consumers’ well-being? Conceptual Model As argued above, automated driving potentially has both a direct and an indirect (mediated) impact on well-being. Subjective well-being (SWB) describes one’s well-being through the global evaluation of life satisfaction (LS), positive affect (PA), and negative affect (NA) (Diener, 1984). This tripartite concept of well-being has been widely adopted by researchers, even though the relationship of the three aspects remains in question (Busseri & Sadava, 2011). Busseri and Sadava (2011) provide an overview of five prominent conceptualizations: As three separate components, as a hierarchical construct, as a causal system, as a composite, and as configurations of components. We adhere to Diener’s original model that describes LS, PA, and NA as three separate components. Accordingly, the correlations among the three components are not of primary interest in this model. Therefore, the impact of automated driving on LS, PA, and NA is assessed separately in order to provide a full image of SWB. This leads to the following hypotheses: H1a. Semi-autonomous driving has a positive impact on the level of SWB by increasing positive affect. H1a. Semi-autonomous driving has a positive impact on the level of SWB by decreasing negative affect. H1c. Semi-autonomous driving has a positive impact on the level of SWB by increasing life satisfaction. Driving influences subjective well-being through different mediators. One potential mediating factor, discussed quite controversially in literature, is fun. While non-automated driving shows a higher level of fun than automated driving, still a large majority is fascinated by automated driving (Kyriakidis, Happee, & Winter, 2015) and also a discharge from the actual driving could be perceived as fun. The most relevant perceived benefit of automated driving studied in literature is safety, followed by stress (e.g. Bansal et al., 2016; Karlsson & Pettersson, 2015; Kyriakidis et al., 2015). Therefore, we formulate the following hypotheses: H2a. The impact of semi-autonomous driving well-being is mediated by fun. H2b. The impact of semi-autonomous driving well-being is mediated by stress. H2c. The impact of semi-autonomous driving well-being is mediated by security. Design/methodology/approach Our sample comprises of two groups with a total of 259 respondents. Group 1 contains 111 respondents using automated driving while group 2 contains 148 respondents not using automated driving. In a first step, to test hypotheses H1a to H1c, we use ANOVA to analyse the group’s differences regarding positive affect, negative effect, and life satisfaction. We analyse both the aggregated values and the single items for all three aspects of subjective well-being. ANOVA was conducted using SPSS version 25. In a second step, to test hypotheses H2a to H2c, three multiple parallel mediation models were estimated with ordinary least squares path analysis. Each model consisted of one of the aspects of SWB as the dependent variable as well as the three mediators. The models were estimated using PROCESS version 3.0 (Hayes, 2013) and SPSS version 25. Findings ANOVA shows a highly significant interaction between semi-automated driving and well-being for negative affect, but not for positive affect and life satisfaction. Looking at the items that amount to positive affect, we see that drivers with the new technology have more excitement, pride and interest. But these effects are counterweighted by significantly less activity, determination and attention. In the context of semi-autonomous driving, being less active, attentive and determined can be interpreted as a positive thing (driving more relaxed). Therefore, we adjust the positive affect scale and remove these three items to from the scale for further analysis. Cronbach’s alpha for all three aspects of subjective well-being is 0.73 or above, thus indicating adequate convergence. Mediation analysis (process model 4) on positive affect reveals a significant indirect effect of semi-automated driving moderated by fun. There is no significant mediation effect for safety and stress as well as no significant direct effect of semi-automated driving on positive affect. The parallel mediation model using negative affect as the dependent variable, shows a significant direct effect of semi-automated driving as well as significant indirect effects mediated by safety and stress. Semi-automated driving reduces negative affect directly as well as by increasing safety, which reduces negative affect. It also reduces negative affect by decreasing stress, which is positively linked to negative affect. Fun, however, has no significant effect on negative affect. Last, life satisfaction shows a combination of the effects mentioned above: Automated-driving has a significant positive direct effect on life satisfaction. Furthermore, life satisfaction is influenced positively through increased fun, safety, and decreased stress. Implications ANOVA and mediation analysis show a positive impact of semi-automated driving on subjective well-being, thus contributing to the investigation of new technologies on consumers’ well-being. Using Diener’s tripartite model of subjective well-being, analyses revealed that the positive effect is especially driven by reducing negative affect. Further research is needed to investigate the transformative impact of (semi-) autonomous driving more deeply and broadly. Especially investigations differentiating between target groups of the new technology might be an interesting path to follow, since the impact on the different aspects of SWB might differ (e.g. increase of positive affect for early adopters vs. decrease of negative affect for people with reduced mobility). Furthermore, our investigation contributes to the conceptual discussion about the structure of the tripartite model of subjective well-being. The fact that life satisfaction as a dependent variable, to some extent, combines the effects observed for positive and negative affect indicates that the three aspects are causally linked instead of being separate. Researchers have promoted a system where positive affect and negative affect are conceptualized as inputs to life satisfaction before (Busseri & Sadava, 2011). Last, our findings give directions to marketing executives for marketing new technologies in general and (semi-)automated driving specifically. First, practitioners need to think about the well-being impact of their technology, i.e. evaluate if it increases well-being by increasing positive affect or by decreasing negative affect. The two paths lead to different marketing measures and ways to promote the technology. More specifically, for semi-autonomous driving a mixed strategy commends itself. It is essential to demonstrate that the new technology reduces the pains of driving while being fun at the same time.

The estrogen-mediated effect of mesenchymal stem cells (MSCs) is a highly critical factor for the clinical application of MSCs. However, the present study is conducted on MSCs derived from adult donors, which have different physiological status with steroid hormonal changes. Therefore, we explores the important role of 17β-estradiol (E2) in MSCs derived from female and male newborn piglets (NF- and NM-pBMSCs), which are non-sexually matured donors with steroid hormones. The results revealed that in vitro treatment of MSCs with E2 improved cell proliferation, but the rates varied according to the gender of the newborn donors. Following in vitro treatment of newborn MSCs with E2, mRNA levels of Oct3/4 and Sox2 increased in both genders of MSCs and they may be correlated with both estrogen receptor α (ERα) and ERβ in NF-pBMSCs, but NM-pBMSCs were only correlated with ERα. Moreover, E2-treated NF-pBMSCs decreased in β-galactosidase activity but no influence on NM-pBMSCs. In E2-mediated differentiation capacity, E2 induced an increase in the osteogenic and chondrogenic abilities of both pBMSCs, but adipogenic ability may increased only in NF-pBMSCs. These results demonstrate that E2 could affect both genders of newborn donor-derived MSCs, but the regulatory role of E2 varies depending on gender-dependent characteristics even though the original newborn donors had not been affected by functional steroid hormones.

Insects are among the most diverse groups of animals on the planet, representing more than half of all known living organisms. These insects are found in nearly every environment. Although humans regard certain insects as pests and attempt to control them using insecticides, most insects perform complex ecological functions, and provide either direct or indirect economic benefits to humans. Recently, the importance of insects used as food sources or as pets has increased in many countries, including Korea. In addition, several insects have a strong influence on people's emotion. Insect-mediated mental healthcare program is designed to help people who have disorders with physical, behavior and development. Children who have mental disorder, the experimental group that was provided with an insect-mediated mental healthcare program over a total of 8 sections, one section per week, 60 minutes per section, followed by pre-test and post-test. They responded to therapeutic effect after the completion of the program. Further research on the basis of this study is expected to help children with emotional therapy in other areas.

This study investigated whether orthodontic force influences the production of osteoprotegerin (OPG) and receptor activator of nuclear factor-kappa B ligand (RANKL) in vivo, both of which are affected by cortical activation. Mechanical force was applied to the maxillary premolars of orthodontic patients by fitting the transpalatal arch prior to cortical activation of the gingival tissue. Gingival crevicular fluid (GCF) samples were then collected from each patient using paper strips before and after 1, 3, 7 or 14 days of treatment. The OPG and RANKL levels in the GCF were determined by enzyme-linked immunosorbent assays. The levels of OPG were significantly increased after 1 day of fitting the appliance and decreased to basal levels at 3 days after fitting. In contrast, the RANKL levels were dramatically decreased at 1 day after fitting, but recovered to those of the untreated control at 3 days after the force application. The force-mediated changes in the OPG and RANKL levels of the GCF were unaffected by cortical activation during these experimental periods. Collectively, these results suggest that an acute and severe change between the OPG and RANKL levels plays an important role in stimulating the cellular responses required for alveolar bone remodeling by orthodontic treatment.

The purpose of this study was to measure the effects of attitude toward fish eating, Health involvement and convenience on the relationship between fish consumption and age. A total of 235 questionnaires were completed. Structural equation model was used to measure the causal relationships between constructs. Results of the study demonstrated that the structural equation analysis result for the data also indicated excellent model fit. The effects of age on involvement and convenience were statistically significant. The effects of age on attitude and consumption was not statistically significant. As expected, the involvement had a significant effect on attitude and consumption. The attitude and convenience had a significant effect on consumption. The effect of involvement on convenience was not statistically significant. Moreover, the attitude, involvement and convenience played a mediating role in the relationship between consumption and age. The involvement played a mediating role in the relationship between attitude and age. The involvement played no mediating role in the relationship between convenience and age. The attitude and convenience played no mediating role in the relationship between consumption and involvement.

Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of Acanthopanax senticosus extract (AS) on hepatic ischemia-reperfusion. To explore the protective effects of A. senticosus extract injection (ASI) on hepatic ischemia-reperfusion injury rats animal model were used. After the development of HIRI by using clamping method rats were then randomly divided into five groups. Different doses of AS were administered in HIRI rat model. The level of ALT, AST, and MDA content in serum were detected in sham and HIRI groups. The activity of SOD, MPO and Ca2+-ATPase, content of MDA, and cAMP in hepatic tissue were also measured. Expression of Bcl-2 and Bax protein were detected by immunohistochemical staining method. Compared with sham group, ASI has the protective effect on the HIRI model in rats. Blood levels of ALT, AST, SOD, MPO, and MDA were significantly lower in ASI group compared with HIRI. Indeed SOD and Ca2+-ATPase activities, MDA content, and cAMP level were improved in ASI group. Furthermore, Bcl-2 and Bax protein were improved in ASI group compared with only HIRI group. These results suggest that AS may provide potential ameliorative therapy by inhibiting the damage signaling mechanism in hepatic ischemia/reperfusion injury model.

This study is aimed to examine the mediated effects of consumer recognition in relationship of local food tour experience and intention of action in the revitalization of local food. Questionnaire survey target was women in 30s and 40s. The local food tour experience is independent variable, intention of action is dependent variable, and consumer recognition is analyzed as mediated variable. As a result, consumer recognition which is mediating variable has two subordinated variables. One is direct affect and the other is indirect affect. Between local food tour experience and intention of action, there was partial mediating effect. Thus, through tour experience, consumer can have positive recognition of freshness, safety, health, taste, price, job creation and relationship. That affects to the intention of action. Based on the results of the study, it is necessary to learn success case for marketing revitalization, and develop and operate experiencing tour education program to manage customer continuously.
