  • The purpose of this study is to show that the effectiveness of utilitarian versus hedonic attributefocused advertisement on product evaluation depends on the arousal level of positive emotion, and to explore mediation effect of cognitive response to utilitarian attribute-focused advertisement and affective response to hedonic attribute-focused advertisement on the effectiveness of utilitarian versus hedonic attribute-focused advertisement. This research employs a 2 (arousal level: mild vs. elevated) × 2 (advertisement type: utilitarian vs. hedonic) between-subjects design, and 200 undergraduate students participate in the experiment, in which there are 50 students at each experimental group. The results of ANCOVA with positive emotion level as a covariate on advertised product evaluation show significant interaction effect of arousal level and advertisement type, and no effect of positive emotional level. Both of the mediation effects of the cognitive response and those of the affective response are significant. Participants under mild (elevated) arousal of positive emotion more positively evaluate the product in utilitarian (hedonic) attribute-focused advertisement. The positive effect of utilitarian (hedonic) attributefocused advertisement on product evaluation is partially mediated by cognitive (affective) response to the advertisement when consumers are under the mild (elevated) arousal of positive emotion. The results of this study show that advertisers should use utilitarian (hedonic) attribute-focused advertisement to consumers under the mild (elevated) arousal of ambient positive emotion, which should be searched by exploring what kind of event they have experienced.

  • As the elderly population is increasing, Alzheimer's disease (AD) has become a global issue and many clinical trials have been conducted to evaluate treatments for AD. As these clinical trials have been conducted and have failed, the development of new theraphies for AD with fewer adverse effects remains a challenge. In this study, we examined the effects of Theracurmin on cognitive decline using 5XFAD mice, an AD mouse model. Theracurmin is more bioavailable form of curcumin, generated with submicron colloidal dispersion. Mice were treated with Theracurmin (100, 300 and 1,000 mg/kg) for 12 weeks and were subjected to the novel object recognition test and the Barnes maze test. Theracurmin-treated mice showed significant amelioration in recognition and spatial memories compared those of the vehicle-treated controls. In addition, the antioxidant activities of Theracurmin were investigated by measuring the superoxide dismutase (SOD) activity, malondialdehyde (MDA) and glutathione (GSH) levels. The increased MDA level and decreased SOD and GSH levels in the vehicle-treated 5XFAD mice were significantly reversed by the administration of Theracurmin. Moreover, we observed that Theracurmin administration elevated the expression levels of synaptic components, including synaptophysin and post synaptic density protein 95, and decreased the expression levels of ionized calcium-binding adapter molecule 1 (Iba-1), a marker of activated microglia. These results suggest that Theracurmin ameliorates cognitive function by increasing the expression of synaptic components and by preventing neuronal cell damage from oxidative stress or from the activation of microglia. Thus, Theracurmin would be useful for treating the cognitive dysfunctions observed in AD.

  • The purpose of this study was to examine the effects of stroke patients' cognitive score on their the activities of daily living. The subjects of this study were 30 stroke patients who were admitted to T$\breve{a}$e-Bong hospital from November, 2002 to March, 2003. The subjects were administerd an MMSE as a cognitive assessment and an MBI as a functional assessment upon referral to physical therapy initially. The results were as follows: 1. The MMSE scores for the stroke patients were related to the patients' abilities to perform their activities of daily living. The changes of MBl scores significantly correlated with the changes of MMSE scores (p<.05). 2. The subjects with left hemispheric lesion scored higher in MMSE than those with right hemispheric lesions (p<.05). 3. The hemispheric lesions did not significantly affect the activities of daily living score (p>.05).

  • Until now, neuropsychological tests can diagnose the brain dysfunction, however, cannot distinguish the objective data of experiment enough to distinguish the relationships between brain dysfunction and cerebropathia. In this paper, an automatic cognitive test equipment system with 6-axis motion sensors was proposed for the automation of neuropsychological tests. Fist-Edge-Palm(FEP) test and Go-no go test were used to evaluate motor programming of frontal lobe. The motion data from the specially designed motion glove are transmitted wirelessly to a computer to detect the gestures automatically. The healthy 20 and 11 persons are investigated for the FEP and Go-No go test, respectively. The recognition rates of gestures of FEP and Go-No go test are min. 91.38% and 89.09%. In conclusion, the automations of cognitive tests are successful to diagnose the brain diagnostics quantitatively.

  • In this paper, we investigate an adaptive cognitive radio (CR) scheme where a sensing duration and a detection threshold for spectrum sensing are adaptively determined according to the channel condition in a fading channel. We optimize the sensing duration and detection threshold of a secondary user to maximize the performance of the secondary user guaranteeing a primary user's secure communication. In addition, we analyze the effect of channel fading on the optimization of the sensing duration and detection threshold. Our numerical results show that the performance of the adaptive CR scheme can be drastically improved if a secondary user can take the advantage of channel information between primary and secondary users.

  • The paper tests the above socio-cognitive model with four empirical case studies of leading Korean science and technology research and technology transfer organizations. The case studies demonstrate clear differences in individuals' frames about the technology transfer process and arising conflicts. As a result, technology transfer process is not fully controllable and is highly contextual. We argue, whereas public policy in countries approaching technology frontier provides essential support for defining and exploiting best practices (routines/pathways) for technology transfer at organizational level, they have not matured enough to support the timely identification and resolution of conflicts between individual actors, hence the inefficiencies. Therefore, among others, public policy for technology transfer could consider allowing an inclusive approach to recognition of best practices for technology transfer and innovation processes, increased social interactions between technology transfer actors, and their training on resolution of individual level cognitive conflicts.

  • The increased popularity of group-buying deal promotions has made research efforts grasping the importance of involvement on the positive reactions of consumers. This is due to the fact that consumer purchasing behaviors are highly likely to differ depending on a particular consumer's involvement level, referring to the basic interest in or importance of a group-buying purchase. In this regard, this paper (1) investigated the effects of involvement on purchase behaviors; and (2) examined whether the proposed relationships may vary depending on a consumer's deal prone propensity. Results revealed that a consumer's cognitive involvement in a restaurant promotion affects emotional involvement, ultimately leading to purchase intention. In addition, a consumer's deal proneness tendency was revealed to moderate the relationship between cognitive involvement and emotional involvement. Compared to low deal-prone consumers, high deal-prone consumers tended to have a higher level of emotional involvement resulting from cognitive involvement. Managerial implications and directions for future research are provided.

  • The purpose of this study is to examine how the perceived physical environments of hotel kitchens influence cooking employees' internal responses. According to the analysis results of this study, except Hypothesis 2 which was rejected in this study, all the hypotheses were partially accepted. These results support the research hypotheses of this study that comfort, spatiality, and convenience as physical environments will have significant effects on emotional response and cognitive response. Also, equipment use as convenience had statistically significant effects on both emotional response and cognitive response whereas working environment as comfort and kitchen circulation and working space as spatiality had no effect. Therefore, kitchen environment should be set up in the direction of guaranteeing kitchen convenience to the maximum, and the further researches on the constituent factors which have no effect on emotional response and cognitive response should be proceeded continuously.
