  • Purpose - This study investigates whether the effectiveness of self trait-advertisement versus communion-focused advertisement on product evaluations depends on a type of pride felt as ambient emotion. It also explores whether the mediating roles of cognitive and affective response to the effect of the advertisement type on product evaluation are moderated by types of pride such as hubristic pride or authentic pride. Research Design, Data, and Methodology - This research uses a restaurant service as the experimental object and employs a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) between-subjects design, with cognitive response and affective response as within-subject. Each experimental group consisted of 40 undergraduate students assigned to participate in the experiment. One questionnaire from the authentic pride and self-trait focused advertisement group and two questionnaires from the hubristic pride and communion-focused advertisement group were removed due to answer errors, resulting in a participant number of 157. The author conducts a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) ANOVA on advertised product evaluations, and to better understand the interaction effects, also conducts separate analysis of the hubristic and the authentic pride groups. Additionally, the study conducts mediated moderation analysis to check the mediation role difference of the cognitive response and the affective response to each advertisement on the interaction effects on product evaluations between the hubristic and the authentic pride groups. Results - The findings indicate that participants in the hubristic pride group more positively evaluate the product in self-trait focused advertisement, whereas participants in the authentic pride group more positively evaluate the product in communion-focused advertisements. In addition, the mediating role of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation is partially moderated by the pride type. However, the mediating role of affective response on the positive interaction effect of advertisement type and pride type on the product evaluation is not moderated by the pride type. Conclusions - The results of this study contribute to advertisement theory development by exploring interaction effects of ambient pride type and advertisement type on product evaluation, as well as to the theory of consumer behavior by exploring how pride type moderates the mediating roles of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation. From the perspective of the current research, advertisers should research what kinds of events consumers have experienced to increase the effectiveness of their advertisements, and use self-trait advertisements when consumers are grouped under ambient hubristic pride, and use communion-focused advertisements when consumers are grouped under ambient authentic pride. However, future research is necessary to discover the reasons why the mediating role of affective response to advertisements in the interaction effects of pride type and advertisement type on product evaluation is not moderated by pride type.

  • This study examined in what category that the knowledge dimension and the cognitive processes dimension are described based on 'A revision o Bloom's taxonomy of educational objectives' in oral health education textbooks. Oral health education and practice from Educational Objectives of Dental Hygiene Department(Korea dental hygienist Prof Council, 2009) were selected to analyze a textbook, the body contents was analyzed in the knowledge dimension, and the activity was analyzed in cognitive processes dimension. Three experts were selected as a corder for reliable analysis. As a result of this study, the knowledge dimension in oral health education textbook was focused on the categories of factual knowledge and conceptual knowledge in textbook analysis based on 'A revision of Bloom's taxonomy of educational objectives', and the category dimension of 'understand' showed to be the most for the cognitive processes dimension. Moreover, there was no 'meta cognitive knowledge' that conforms to a higher-order thinking and the category dimensions of 'analyze', 'evaluate', and 'create' took very low proportion or did not exist. Conclusion, Oral health education textbooks were analyzed to fragmentary and Memorizing the level knowledge. Thus we have to develop oral health education textbooks reflected a variety of cognitive and knowledge dimension.

  • The purpose of this study was to investigate the effects of different types of exercise training on ẞ-Amyloid, Brain-Derived Nerurotrophic Factor(BDNF) and cognitive function in mice with Diabetes Mellitus Group(DM.G). 24 male C57BL/6 mice were randomly assigned to the control (C.G. n = 6) and Diabetes Mellitus Group(DM.G. n = 18) groups. After the Diabetes Mellitus induction period, the DM group was subdivided into DM.G. + sedentary (DM.G., n = 6), DM.G. + endurance exercise (A.G, n = 6), and DM.G. + resistance exercise (R.G., n = 6). The A.G. and R.G performed treadmill and ladder climbing exercises 5 times per week for 8 weeks, respectively. After 8 weeks the results are as follows: ẞ-Amyloid showed higher levels of DM.G. than in A.G., R.G., and C.G., but was not statistically significant(p>.05). BDNF was significantly lower in DM.G. than in C.G., A.G., and R.G.(p <0.05). The Y-maze task performance for cognitive function was significantly lower in DM.G. than in C.G., A.G., and R.G.(p <0.05). These results predict that diabetes can negatively affect ẞ-Amyloid, BDNF and cognitive function. It can also be predicted that low-intensity exercise can positively improve ẞ-Amyloid, BDNF and cognitive function regardless of the type of exercise.

  • Objective: To develop and verify the usability of a cognitive rehabilitation system with diverse cognitive functional levels based on tangible objects for the elderly population. Methods: A study was conducted to investigate the system's strengths and weaknesses by upgrading it with responses from two groups of 15 patients and 4 occupational therapists. After undergoing three forms of training - regarding executive function, memory, and concentration for a total of 20-30 min, the participants were asked to answer a structured questionnaire about contents of the three forms of training, hardware including the tablet PC functioning as a CPU and display media and tangible objects, and satisfaction of experiential usage of the system. Results: Both groups responded that the most interesting training area was executive function while the least interesting was concentration. Six participants reported that the size of the screen of the tablet PC was inappropriate, and five responded that the size of the tool was inappropriate. All therapists and 40% of the patients responded that they were satisfied with this system. Conclusion: This system's features include easy manipulation of tangible tools for performing training tasks, easy selection of and training in cognitive areas based on users' needs, and automatic adjustment of difficulty level based on users' performance. The training environment was designed to be similar to the natural environment by using tangible objects in both hands as input devices for the system, and the system was considered as an alternative to the lack of community cognitive rehabilitation specialists.

  • Objective : The purpose of this study was to verify the effect of virtual reality interventions (VRIs) on cognitive function in individuals with stroke through a systematic literature review and meta-analysis. Methods : We reviewed randomized controlled trials (RCTs) the last 10 years using academic databases. PubMed, MEDLINE, and CINAHL were used for international studies, and DBpia, KISS, Kyoboscholar, and e-article were used for Korean studies. For the quantitative meta-analysis, subgroups of outcomes were classified into general cognitive function (G-CF), attention and memory (A&M), and executive function (EF). Results : Nine RCTs were analyzed. The total number of participants was 271 (140 in the experimental group). The effect size (Cohen's d) was estimated using a random effects model. The effect sizes of the outcome subgroups of were as follows: small to medium for G-CF (d=0.422; 95% CI: 0.101~0.742; p=0.010), small for A&M (d=0.249; 95% CI: -0.107~0.605; p=0.170), and medium for EF (d=0.666; 95% CI: 0.136~1.195; p=0.014). Conclusion : Considering the various stimuli provided by the virtual environment and the results from available research, virtual reality should be applied to interventions for integrated cognitive functions. In addition, it would be appropriate to be used as an additional intervention to traditional cognitive rehabilitation for stroke.

  • In this paper, we introduce the SNUDM-G, a diffusion model analysis tool with improved computational speed. Although the diffusion model has been applied to explain various cognitive tasks, its use was limited due to computational difficulties. In particular, SNUDM(Koh et al., 2020), one of the diffusion model analysis tools, has a disadvantage in terms of processing speed because it sequentially generates 20,000 data when approximating the diffusion process. To overcome this limitation, we propose to use graphic processing units(GPU) in the process of approximating the diffusion process with a random walk process. Since 20,000 data can be generated in parallel using the graphic processing units, the estimation speed can be increased compared to generating data through sequential processing. As a result of analyzing the data of Experiment 1 by Ratcliff et al. (2004) and recovering the parameters with SNUDM-G using GPU and SNUDM using CPU, SNUDM-G estimated slightly higher values for certain parameters than SNUDM. However, in term of computational speed, SNUDM-G estimated the parameters much faster than SNUDM. This result shows that a more efficient diffusion model analysis for various cognitive tasks is possible using this tool and further suggests that the processing speed of various cognitive models can be improved by using graphic processing units in the future.

  • As social beings, we need to understand others' actions as quickly and accurately as possible. Action understanding can occur at many levels. We sometimes grasp others' intentions unintentionally. Other times, however, we have to expend effort to draw inferences about their goals. In the context of joint action, the joint Simon effect demonstrates that actors are influenced by the unintended representation of a co-actor's actions. This effect has been described as quasi-automatic, but it is unclear if the effect is automatic enough to be immune to cognitive load. Thus, we asked participants to complete a joint Simon task with or without a concurrent working memory task. One group of participants maintained a single digit in their mind during working memory load blocks (low-load group), while the other group maintained five digits (high-load group). As a result, the low-load group showed a joint Simon effect both during no-load and low-load blocks. In contrast, the high-load group had no joint Simon effect during either no-load or high-load blocks. These results suggest that the joint Simon effect is not an automatic phenomenon given that it requires cognitive resources. Actors in a joint task may represent a co-actor's actions in their task set, but only when cognitive resources are available.

  • In the 2009 revised science curriculum, comprehensive verbs such as 'know (38%)' and 'understand (46%)' are used in more than 80% of the achievement standard. Many readers, such as teachers, textbook makers, etc. have difficulties in interpreting the meaning of achievement standard sentences with these comprehensive verbs. On the other hand, 'Trends in International Mathematics and Science Study (TIMSS)' uses more various and specific verbs to express the cognitive domain. In this study, we analyzed the 2009 revised science curriculum achievement standard focusing on the TIMSS cognitive domain assessment framework. We divided achievement standard to 228 sentences and three teachers analyzed the meaning of verbs in achievement standard. There were two main results of this study. First, the verb 'Know' was analyzed into different kinds of meanings, such as 'Describe (27%)', 'Recall/Recognize (25%)' and 'Relate (17%)', etc; and the verb 'Understand' was analyzed into 'Explain (37%)', 'Relate (27%)' and 'Describe (21%)', etc. Second, there appeared to have a disagreement among the three analysts during the process of interpreting the achievement standards when the level and scope of the contents of each grade is not clear. This study concludes that there's a need for continuous discussion on the use of verbs in achievement standard to promote clearer expressions for better understanding.

  • 최근 들어 휴대성을 강조한 휴대폰이나 PDA 같은 다양한 모바일 기기의 등장으로 언제 어디서나 원하는 정보를 탐색할 수 있게 되었으나 기기는 점점 작아지는 반면, 기능은 증가하고, 많은 기기들이 데스크톱 인터페이스를 그대로 차용하여 작은 모바일 기기에는 적합하지 않은 결과를 낳고 있다. 따라서 본 연구는 청각 피드백을 이용한 공간정보 단서를 제공하여 작은 기기의 사용성을 높이는데 초점을 두고 있다. 이를 위하여, 실험 1에서는 두 가지 메뉴 구조에서 세 가지 청각 피드백의 영향을 조사하였는데, 격자메뉴와 한 줄 메뉴에서 각 청각피드백이 미치는 영향과 사용자의 선호도를 조사하였다. 실험 결과, 격자메뉴에서 수행이 좋았으나, 청각 피드백 유형별 수행 차이는 나타나지 않았고, 각 피드백에 대한 선호도에서도 차이가 나타나지 않았다. 실험 2에서는 실험 1에서 사용된 정보를 제공하는 청각적 피드백을 음 높이와 음의 개수 속성으로 세분화하여 PDA에서 메뉴 탐색 수행을 4블록으로 나누어 조사하도록 설계하였다. 실험 결과, 음 높이 속성만 갖는 피드백은 블록이 진행되면서 반응 시간에 있어서 피로도가 나타난 반면, 음 개수 속성만 갖는 피드백은 블록이 진행되어도 피로도가 나타나지 않았다. 한편, 두 속성을 모두 갖는 피드백은 블록이 진행되면서 보행 속도가 유의미하게 줄어드는 것을 발견하였다. 본 연구의 결과는 앞으로 유비쿼터스 환경에서 사용자에게 효율적인 청각 피드백을 통해 공간 정보를 제공함으로써 휴대기기의 사용성을 높일 수 있는 한 가지 가능성을 제시한다는 데 의의가 있다.

  • Purpose: The purpose of this study was to identify the effects of a cognitive behavioral stress management program on perceived stress, coping strategies, and cortisol in people with Diabetes Mellitus Type 2. Method: Patients with type 2 diabetes were recruited from of a public health center in an urban area. Thirty-five participants (experimental group=17, and control group=18) enrolled. The experimental group received small group-based cognitive behavioral stress management training for eighty minutes per session, once a week for eight weeks. Data were collected at baseline and ninth week for perceived stress, affect-oriented coping, problem-oriented coping, and cortisol. The data were analyzed using SPSS 12.0. Results: The experimental group had significantly less perceived stress (t=-9.82, P<.001) and cortisol (t=-2.14, p=.040) than the control group. No significant group differences were found in affect-oriented coping (t=-.43, p=.673) or problem-oriented coping (t=1.40, P<.170). Conclusion: These results suggest that a cognitive behavioral stress management program can have positive effects on perceived stress and cortisol in patients with diabetes mellitus type 2. Further research with a larger sample and for a longer period is needed to expand our understanding of the effects of the program for patients with diabetes mellitus type 2.
