  • More than 90 percent of traffic accidents were caused by human errors in driving situation. However, the ergonomic studies were not enough to prevent these human errors. Especially, drivers acquire more than 70 percent of information using the vision, and this shows the importance of consideration about the driver's visual cognition characteristics. Consequently, the driver's cognition time and the cognition accuracy were measured for the Instrument Panel(IP) of vehicle cockpit in this study. For the experiment, subjects were divided in two groups. The first group of subjects had their own vehicles and the driver license, and the second group of the subjects didn't have own vehicle but had the driver license. IP Images were used in the experiment and the each image was made by changing layout of objects within devices. The results showed that there were no differences for the cognition time and the accuracy between images within the group, and the results between the groups showed the same trend.

  • Mothers are a powerful consumer force in the children clothing market, and somatotype plays an crucial role on their evaluation of clothing and decision to purchase. It is therefore essential to identify the roles of mother's somatotype & somatotype cognition in relation to purchasing of children clothing. This study aimed to investigate the effects of mother’s actual somatotype & somatotype cognition on their children’s clothing evaluative criteria. In order to compare the clothing evaluative criteria of the groups and among the groups by mother’s somatotypes at the point of children’s clothing purchases, mother’s actual somatotype & somatotype cognition of their self and their children were adopted as variables. Total usable questionnaires were obtained from 147 middle-aged mothers of students aged between 10 & 13. Results indicated that practical, commodity & symbolic dimensions of children’s clothing evaluative criteria were used differently by each group to decide on purchase of clothing for thin, moderate & heavy children. This study provides important commercial information about mother’s actual somatotype & somatotype cognition related to their children’s clothing evaluative criteria, and as such can be used strategically to the effective communication with consumers.

  • In this study, an eye-tracking program that can confirm a design cognition process was developed for the purpose of presenting strategic methods to create fashion images, and the program was used to identify what effects fashion models' external characteristics have on the cognition of design. The data for analysis were collected through an eyemovement tracking experiment and a survey, with the focus on the research problem that differences in models' external uniformity will lead to differences in the eye movement for perceiving models and design as well as the image sensibility. The results of the analysis are as follows. First, it was confirmed that the uniformity of model types and the simplicity/complexity of design led to differences in the eye movement directed at design and models and the gaze ratio. Consequently, it is deemed that models should be selected in consideration of the characteristics of design and the intention of planning when creating fashion images. Second, it was found that in terms of the cognition of design, external conditions of models affect design sensibility. A change in models led to a subtle difference in sensibility cognition even when the design condition did not change. Thus, not only the design but also model attributes are factors that should be considered important in fashion planning.

  • The purpose of this study was to analyze the impact of climate change cognition on clothing behavior of fashion consumers to understand the impact of climate change on the fashion system. An online survey was conducted of 385 people in their 20s-50s working in the fashion industry as well as general consumers. Data collected from surveys were analyzed by factor analysis and t-test. Results are as follow: First, climate change cognition consists of four sub-dimensions, which are 'knowledge of climate change' and 'recognition of climate change in Korea'. Second, clothing behavior related with climate change consists of six sub-dimensions, which are 'environmentally-friendly fashion purchases', 'new clothes-wearing style affected by climate change', 'ethical fashion consumption', 'pursuit of functional fashion', 'pursuit of seasonless fashion', and 'clothes-wearing in response to climate change.' Last, the group with higher cognition of climate change than the group with lesser cognition had significantly higher degree of trying new styles created because of climate change, making ethical fashion purchases, pursuing functional fashion, and wearing clothes in response to climate change.

  • Purpose: This study investigates the level of expectancy, cognition, and work condition among smokers with respect to the smoking cessation clinics. Methods: The study participants included over 503 smokers aged 30 yr and in five districts of G city. The researcher and assistants personally visited homes and workplaces of the participants between November 20 and November 30, 2008 for the survey. Results: The subjects learned to smoke from their friends and started smoking when they were 15 out of curiosity. They smoked more than one cigarette every day. With respect to cognition, 67.5% of the subjects had no intention to utilize smoking cessation clinics, and 71.7% were unaware of their benefits. Those with a high level of cognition regarding smoking cessation clinics were generally in their 60s, married, residents in the Southern and Western Districts, service or technical workers, and hikers. The expectancy for the clinic was high among those who were married, Catholics, and golfers. Conclusions: The results suggest that smoking cessation may be achieved by increasing the level of cognition and expectancy among smokers. In this regard, providing information and implementing positive publicity campaigns targeting families, Places of worship, and workplaces may be beneficial.

  • Level 3 autonomous vehicles require conditional autonomous driving in which autonomous and manual driving are alternately performed; whether the driver can resume manual driving within a limited time should be examined. This study investigates whether the demographics and subjective driving tendencies of drivers affect the take-over performance. We measured and analyzed the reengagement and stabilization time after a take-over request from the autonomous driving system to manual driving using a vehicle simulator that supports the driver's take-over mechanism. We discovered that the driver's reengagement and stabilization time correlated with the speeding and wild driving tendency as well as driving workload questionnaires. To verify the efficiency of subjective questionnaire information, we tested whether the driver with slow or fast reengagement and stabilization time can be detected based on machine learning techniques and obtained results. We expect to apply these results to training programs for autonomous vehicles' users and personalized human-vehicle interfaces for future autonomous vehicles.

  • The purpose of this study is to examine green consumer behavior (green product purchasing behavior and green consumption life) affected by demographical characteristics, and cognition degree of green life (cognition of a green indicator, a green life catalyst system, and environmental problems). It's also to promote strategy and suggest effective activation plans for the vitalization of green consumer behavior. To carry out the task, verification of credibility, multiple regression analysis, two-step cluster analysis, and multinomial logistic analysis were used. The results are as follows: First, the factors that effect green product purchasing behavior were gender, age, cognitive of a green indicator, carbon points system, electricity peak hour system, and seriousness of environmental damage due to lifestyle. Second, the factors that effect green lifestyle were gender, age, carbon grade indicator system, cognition of a green system, and the seriousness of environmental damage due to lifestyle. Third, the comparative group characteristic analysis showed low rates for careless green consumer behavior groups compared to the passive green consumer behavior groups in cognition of a green indicator, green system, and environmental problems. For active green consumer behavior groups, the analysis showed high rates in cognition of carbon grades, eco-labeling, electricity peak hour system, and environmental damage due to lifestyle. In order to encourage green consumer behavior, it's evident that cognition of a green indicator, a green life catalyst system, and environmental problems need to be improved through strategic education and continuous encouragement.

  • Purpose: Caffeine is the most widely consumed psychostimulant. It is often adopted as a tool to modulate brain activations in fMRI studies. However, its pharmaceutical effect on task-induced deactivation has not been fully examined in fMRI. Therefore, the purpose of this study was to examine the effect of caffeine on both activation and deactivation under sustained attention. Materials and Methods: Task fMRI was acquired from 26 caffeine naive healthy volunteers before and after taking caffeine pill (200 mg). Results: Statistical analysis showed an increase in cognition-load dependent task activation but a decrease in load dependent de-activation after caffeine ingestion. Increase of attention and memory task activation and its load-dependence suggest a beneficial effect of caffeine on the brain even though it has no overt behavior improvement. The reduction of deactivation by caffeine and its load-dependence indicate reduced facilitation from task-negative networks. Conclusion: Caffeine affects brain activity in a load-dependent manner accompanied by a disassociation between task-positive network and task-negative network.

  • The purpose of this study is to present the cognition of speculative aesthetics in the architectural space. Architectural space as the subject of the aesthetical study has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is also true that academic approach to the architectural space as per the aesthetic recognition has not been done so satisfactorily. The transcendental subjectivity as the aesthetic cognitive viewpoint of the architectural space means speculative aesthetics and the understands the essential meaning of the function and composition The conclusions of this study are as follows : The formalistic cognitive concepts including organic functional space between the whole and the part and anti-cubic synchronous space are included in the architecture of the speculative cognition, and finally the contextual cognitive concepts including the restoring analogical space of the in-depth constituent factors and associated centripetal spaces.

  • Background: Human body is formed of symmetric bilateral structures that are comprised of eye, upper arm, lower arm and etc. but, we are used only dominant components. The purpose of this study was to analysis length cognition ability in dominant eye. Methods: Total 88 persons (male 18, female 70) were participated in this study. They were tested with ‘hole in the card’ test for identification of dominant eye's side, then the length cognition ability was measured in right & left axillary level by describing 10cm line. Results: The results by independent t-test were as follows. In difference of length cognition ability in right axillary level between right dominant eyed group & left dominant eyed group, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). In left axillary level, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). Conclusion: These result can be applied to the learning of palpation & observation skill in physical therapy, although this study was not identify a relation between dominant eye & dominant hand.
