  • This paper describes the effect of a robot cognitive rehabilitation program on cognitive functions for the elderly with mild cognitive impairment, and compares it with traditional cognitive therapy programs. Three experiment groups including cognition therapy group, robot cognitive rehabilitation group, and hybrid group have been sampled and one comparative group has been organized for this research. 32 old people whose ages are between 61 and 88 with mild cognitive impairment participated in the programs with an admission of W care hospital. According to the program results, the cognitive therapy program alone had shown a positive effect on the attention function, and the robot cognitive rehabilitation program alone had a positive effect on the total intelligence and memory function. However, a simultaneous operation with both programs had shown a positive effect on the three intelligence areas such as total, basic, and management quotients as well as attention and memory functions as subsidiary factors. This paper has verified that the proposed robot cognitive rehabilitation program makes a positive effect on a cognitive function and plays a complementary role with traditional cognitive therapy programs.

  • This study tried to find the effect to cognitive structure upon the momentum effect. The previous studies showed that the momentum effect is influenced by students' cognitive levels and the abstractness of test items. The cognitive structure is examined by cognitive level and cognitive style. Cognitive levels and cognitive styles are determined by GALT and GEFT respectively. The research method used in this study is time series design. The period is 50 days. The period is divided into "pre-test", "intervention-test", "post-test". Pre-test period is 5 days and in this period class instruction does not exist Intervention-test period is 30 days and in this period class instruction exist Post-test period is 15 days and in this period class instruction does not exist. Field independent students showed longer momentum effect than field dependent students. Formal level students showed less ratio of decrease on post-test than nonformal level students. Momentum effects is not artifact but the essential characteristics of science study.

  • Purpose: In general, franchise business models can generate higher returns and profits than non-franchise businesses. Therefore, it is necessary to study customer-based foodservice franchise brand awareness and service quality. The purpose of this study is to investigate the effect of service quality and brand awareness of foodservice franchises on attitudes divided into cognitive and affective attitudes and revisit intentions. Through this study, we intend to establish a structure that leads to service quality and brand awareness-cognitive attitude and affective attitude-loyalty. Research design, data, and methodology: In order to verify the hypothesis of this study, the survey was conducted among general consumers over the age of 20 who had visited a foodservice franchise within the last 3 months. Among the collected questionnaires, one insincere questionnaire was excluded, and 299 copies were used for analysis. The data collected to verify the hypothesis of this study were analyzed using SPSS 24.0 and AMOS 24.0. Result: First, it was found that the service quality of the foodservice franchise had a positive (+) effect on the cognitive attitude, and the service quality of the foodservice franchise had a statistically significant positive effect on the affective attitude. Second, the brand awareness of the foodservice franchise was found to have a statistically significant positive (+) effect on the cognitive attitude. and the brand awareness of the foodservice franchise had a statistically significant positive (+) effect on the affective attitude as well. Third, cognitive attitude was found to have a statistically significant positive (+) effect on loyalty, and affective attitude was also found to have a statistically significant positive (+) effect on loyalty. Conclusions: First, this study applied the S-O-R theory to the effect of service quality and brand recognition on cognitive attitude, affective attitude, and loyalty. Second, the structure leading to service quality and brand awareness-cognitive attitude and affective attitude-revisit intention was established. Third, attitudes in this study were divided into cognitive attitudes and affective attitudes. In general, attitude is studied as a single dimension as a cognitive attitude, but in this study, attitude was studied by dividing it into a cognitive dimension and an affective dimension

  • This paper tried to analyze the response of air traffic controller(ATC) against abnormal situations using survey based on cognitive strategies suggested by Malakis et al.(2010). The survey designed to empirically analyze the effect of the cognitive strategy factors on organizational effectiveness. The main purpose of this research was as follows: First, it was analyzed both the individual-scale and team-scale factors which constructed the cognitive strategy against abnormal situations. Secondly, how seriously impact the ATC's cognitive strategies on their organizational effectiveness. The organizational effectiveness was divided into such two latent variables as job absorption and job satisfaction. According to the a analysis, it was proven that premeditated act of ATC had a positive significant effect on team-scale cognitive strategies such as teamwork, communication and error management. Moreover, it was found out the team-scale cognitive strategies had also a positive significant effect on job absorption. On the other hands, individual-scale cognitive strategies had no or negative effect on job absorption. Job absorption was proven to have a significant effect on job satisfaction of ATC.

  • From a cognitive perspective, this study investigates the role of emergent leaders in developing team cognition and affecting team performance. With application of the cognitive complexity theory, this study hypothesizes that emergent leaders' cognitive complexity will be positively associated with team cognitive complexity, and that team cognitive complexity will be positively associated with team performance. In addition, team cognitive complexity is hypothesized to mediate the effect of the cognitive complexity of emergent leaders on team performance. To test the research hypotheses, data were obtained from 100 teams comprising a total of 339 undergraduate students who participated in a business simulation game. The findings of this study suggests that the cognitive complexity of emergent leaders is a significant predictor of team cognitive complexity, and that team cognitive complexity is positively related to team performance. Moreover, team cognitive complexity significantly mediates the effect of emergent leaders' cognitive complexity and team performance.

  • This study was conducted to test the effect of cognitive stimulation training on elderly persons with dementia. The design of the research was one group in pre-test-post-test design. The subjects were nine demented persons over sixty years, with mild to moderate cognitive impairment. Training was administered by research assistants on a one to one basis for thirty to forty minutes, three times a week for eight weeks. In order to evaluate the effect of cognitive stimulation training, we measured cognitive function before and after three training sessions each. Data were analyzed using descriptive statistics and a paired t-test analysis using a spss pc package, The results are as follows: 1) The recipients of the training program showed improvement in overall cognitive functioning. The MMSK - K score, recall levels of concepts, daily tasks, personal past history and performance of word fluency were significantly increased after training. 2) There was a significant improvement in cognitive functioning over the training period: recall levels of concepts, daily tasks, past personal history and performance of word fluency significantly increased over the training period progessively, The results suggest that cognitive stimulation training is effective in improving and maintaining overall cognitive function of elderly persons with dementia.

  • This study investigated the influence of socio-environmental variables and cognitive variables on adolescent depression. Subjects were 494 middle and high school students of Deagu. The instrument was a self-report questionnaire; data were analyzed by t-test, stepwise multiple regression and path analysis. Among Socio-environmental variables, social support variables had a stronger effect on depression than stress. Among cognitive variables, automatic thought had a stronger effect on depression than cognitive distortion and socio-environmental variables. In path analysis, social support had a direct effect on cognitive distortion and automatic thought. Automatic thought served as a mediater of the relation between social support and depression. Although adolescent stress resulted in high depression, its effect on depression varied with the level of perceived social support.

  • The purposes of this study were to describe the level of vision and hearing impairments, depression and functional capacity, among Korean institutionalized elderly and to examine the relation-ship between sensory impairments, depression, and functional capacity in these people. The final pupose was to test the cognitive function path model using sensory competencies as predictors. A convenience sample of thirty nine male and 90 female subjects with a mean age of 80.5 were the subjects of this study. The subjects were tested for cognitive function, and vision and hearing impairments. Physical function and social function were measured by observation of designated task performance by the subjects. Their level of de-pression was measured using a Geriatric Depression Scale administered through an interview. Individual subjective ratings of hearing and vision were marked by the subjects, on a ladder scale. The results of the study showed that 48.8% of the subjects had a hearing impairment, 63.5% had a vision impairement, and 36.4% had both a vision and hearing impairement. The four sensory groups (no sensory impairement, hearing impairement, vision impairement, hearing and vision impairement) were tested for differences in depression, physical function, social behavior and cognitive function. The only significant difference that was found was in cognitive function, between the no sensory impairement group and the hearing and vision impairement group(F=3.25, P<.05), Subjective ratings of hearing showed a significant correlation with cognitive function(r=.34, p<.001) and with social behavior(r=.31, p<.001). There was no correlation between subjective vision ratings and cognitive function or social behavior. However there was a significant correlation between vision and hearing(r=.49, p<.001). There was also a significant negative correlation between age and vision(r=-.21, p<.01) and between age and hear-ing(r=-.34, p<.001). There was a significant correlation between depression and physical function (r=-.32, p<.001) but there was no correlation between depression and cognitive function or social behavior. Based on the literature review and the result, this study, a path model of sensory competence-> cognitive function- >social behavior was developed and tested : Perceived vision and perceived hearing were the exogenous variahles and cognitive function and social behavior were the endogeneous variables in the model. The path analysis result demonstrated an accept-able fit (GFI=.997, AGFI=.972, X$^2$=.72 (p=.396), RMSR=.019) between the data and the model. There was a significant direct effect($\beta$=.38) of perceived hearing on cognitive function. There was a significant direct effect ($\beta$=.32) of cognitive function on social behavior. The total effect of hearing on social behavior was $\beta$=.32 including the indirect effect ($\beta$=.12) . However perceived vsion had little effect ($\beta$=-.08) on cognitive function. The result of path analysis confirms that hearing levels influence cognitive function, and both hearing and cognitive function levels influence social behavior. However, vision has little effect on cognitive function or on social behavior. For the next study, a combined model of the pre viously developed environment - >depression- > physical and social function model, and the present cognitive function model, should be tested to further refine the functional capacity model. There also a need for longitudinal study of functional capacity and sencory competence in order to better understand how declining sensory competence influences functional capacity and how it effects in-creasing dependency and nursing needs in the elderly.
