Creativity refers to the ability to generate novel and useful ideas. Understanding the mechanism of creativity and its enhancement is important in order to solve major problems of the modern society and to improve the wellness of mankind. Creativity is a highly heterogeneous and complex ability which should not be conceptualized as a single entity. Thus, the current literature on creativity is based on a component process approach to creativity. The present study introduces cognitive neuroscience research studying the mechanism of divergent thinking, insight, relational thinking and artistic creativity which are the major components of creativity. Based on an expansive review, the early hypothesis of hemispheric asymmetry emphasizing the importance of the right as opposed to the left hemisphere is not supported by scientific evidence. In addition, there is no consensus or consistency on which specific brain region is related to a certain component of creativity. In fact, there is a mixture of studies reporting involvement of various brain regions across all four lobes of the brain. This inconsistency in the literature most likely reflects heterogeneity of the component processes of creativity and sensitivity of the neural response to differences across tasks and cognitive strategy. The present study introduces examples of representative studies reporting seminal findings on the neural basis and the enhancement of creativity based on innovative methodology. In addition, we discuss limitations of the current cognitive neuroscience approach to creativity and present directions for future research.

The purposes of this study was to investigate the effect of inductive Instructional method and deductive one concerning the learners' population genetic concepts and achievement according to learners' cognitive characteristics. For the study, 180 students were sampled from a boys' high school: 90 students for inductive teaching method and 90 students for deductive teaching method. Group Assessment of Logical Thinking(GALT) and Group Embedded Figure Test (GEFT) were used as the measure of cognitive characteristics. The results of this study were as follows. 1) The inductive instructional method was more effective in the understanding of population genetic concepts and their achievement. 2) Inductive instructional method was more effective than deductive one for the learners in formal operational level and in field independent cognitive style. 3) For the learners in a transitional level and field dependent cognitive style, deductive instructional way was more effective than inductive way on the average, but it was not statistically significant. It was turned out that learners' cognitive level was one of important factors when teachers instruct the concept of population genetics.
The purpose of this study was to explore the problem solving strategy for Goldberg machine tasks of the gifted students in elementary science depending on the cognitive style(tendency to field-dependent and field independent). It was aimed to provide suggestions for the features and differences of the problem solving strategies of the gifted students in elementary science according to their cognitive styles. A total of 16 students, from the gifted class of P elementary school in Hwaseong were sampled for the research, cognitive styles Test was conducted to divide the students in teams, and the teams were classified according to cognitive style tendencies to five groups of field-dependent group, weak field-dependent group, mixed group, weak field-independent group and field-independent group. The Goldberg device task given was to make a Goldberg device within the angle framework of (Figure) 1, for a bead to start from the starting point and to reach the final point the last. The results are as follows: First, regarding the plan for producing the device, the stronger the field-independent tendency, they established more specific strategy-reflected plan; the stronger the field-dependent tendency, they established less specific strategy-reflected plan. Second, all cognitive style groups took a limited period of time into consideration, to fabricate the devices for the ball to arrive the last using a fine adjustment rather than many devices. Third, the field-independent group used a lot of logical reasoning; the field-dependent group used a lot of intuitive thinking. Fourth, the field independent group properly utilized strategies such as cooperation and role allocation; the field-dependent group tried to solve the task personally rather than cooperatively with poor role allocation. Fifth, the intermediate mixed group solved the problem better than the inclined groups such as field-dependent or field-independent groups.

The purpose of this study is to provide some basic information for elderly driving safety, by analyzing the current state. This study analyzed 128 survey questionnaires given to senior welfare center user in P city and evaluated Montreal Cognitive Assessment Korean Version(MoCA-K) and Neurobehavioral Cognitive Status Examination(NCSE) for checked 41 owner drivers by questionnaires. 32% of total elderly persons was owner driver, and 56.1% of elderly drivers was driving everyday. 56.1% of elderly persons was driving for 1-2hours per day. 46.3% of elderly persons was using a car for leisure activity and 31.7% of elderly drivers was experienced a car accident. As cognitive function evaluation, some elderly drivers showed scores lower than average in subcategories of cognitive functions for driving a car. So, methodical evaluation system for accurate evaluation of deficit ability and driving re-education system will be required for safety driving of elderly person. In future, a legal approach of government as driver licence management and renewal system will be required for safety driving of elderly person.

This study examined the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet of the Korean multi-domain dementia prevention program on the cognitive functions of the elderly with dementia risk factors. We developed the program including nutrition, exercise, cognitive training, vascular disease prevention, and motivation. One- hundred and fifty-three participants aged 60~79 years with at least 1 dementia risk factor were randomly assigned in a 1:1:1 ratio to the facility-based intervention (FMI), home-based intervention (HMI), and the control group. The nutrition education program consisted of 10 classes over 24 weeks: the FMI received 7 group sessions and three 1:1 sessions, the HMI received 4 group sessions and three 1:1 sessions with 3 homework sessions. The Nutrition Quotient for Elderly (NQ-E) and the Mini Nutritional Assessment (MNA) were used to evaluate nutritional status. The Repeatable Battery for the Assessment Neuropsychological Status (RBANS), Korean Mini-Mental State Examination (K-MMSE), and the Cognitive Complaint Interview (CCI) were used to evaluate cognitive functions. A total of 136 people completed the program with an 11.1% dropout rate. The NQ-E (P=0.009) and RBANS (P=0.001) scores significantly increased in the FMI (N=45) and HMI (N=49) groups compared to the control group (N=42) after the study. The changes in the score of MNA and CCI did not differ significantly between groups. In conclusion, the nutritional intervention which focused on the MIND diet as a part of a multi-domain intervention program had a positive effect on the improvement of healthy eating habits and cognitive function scores in the high-risk dementia group.

The purpose of this study was to evaluate the effects of the non-pharmacological intervention on depressive symptoms in the older adults with mild cognitive impairment. A total of 1,147 studies were retrieved from PubMed, CINAHL, PsycINFO, Science direct, KISS, RISS, and DBPia. Twenty-one studies which met the criteria were selected and the quality assessment was conducted independently by two investigators. The effect size of non-pharmacological intervention was estimated using Comprehensive Meta-Analysis 3.0. The overall effect size turned out to be the medium effect size (Hedges' g=-0.68, 95% CI=-1.01~-0.36). As a result of the subgroup analysis, the intervention type was statistically significant. The effect size of cognitive intervention (Hedges' g=-1.03, 95% CI=-1.43~-0.61) and multi component intervention (Hedges' g=-0.97, 95% CI=-1.63~-0.33) was greater than excise intervention (Hedges' g=-0.53, 95% CI=-1.16~0.03). This study shows that non-pharmacological intervention was also effective in reducing depressive symptoms in the older adults with mild cognitive impairment. Based on the research results, it is expected that various non-pharmacological intervention studies will be attempted to improve cognitive function and depressive symptoms of the older adults with mild cognitive impairment.

The purpose of this study was to examine the types of explanation about different experimental data on students' preconceptions on physical experiment. 45 students were selected from P University by examining their pre-test. The subjects had a scientific conception about a simple pendulum's period of movement, and expected that there was no change in the movement even when the mass of water increased in the can. The students were presented data about pendulum movement inside a can. They recorded this in a blank table and drew a graph about the movement of the pendulum. The responses of students were tested by presenting written anomalous experimental data. Students' recognition, trust about the anomalous data, cognitive conflict, belief change about their preconceptions were examined with written tests also. To measure students' cognitive conflict levels, CCLT (Cognitive Conflict Levels Test) developed in a previous study was used. Some students responded based on preconceptions and regarded the data as manufactured data or experimental error. The students who recognized the anomaly in the situation showed higher cognitive conflict levels than those who didn't recognize the anomaly in the situation. The students who changed their beliefs about preconceptions recognized the data as anomalous situations and showed high cognitive conflict levels than those who didn't abandon their preconceptions. The students who have unchanged beliefs about their preconceptions regarded the data as experimental error.

In this study, in order to confirm the ameliorative effects of onion (Allium cepa L.) flesh and peel on amyloidbeta (Aβ)-induced cognitive dysfunction, we evaluated their in vitro neuroprotection and in vivo cognitive functions. As the result of in vitro neuroprotection, the protective effect of the ethyl acetate fraction of onion flesh (EOF) on Aβ-induced cytotoxicity was similar to that of the ethyl acetate fraction of onion peel (EOP). In the behavioral tests, the EOF and EOP effectively improved the Aβ-induced learning and memory impairments. For this reason, it could be concluded that the EOF and EOP improved the antioxidant activities (superoxide dismutase, oxidized glutathione/total glutathione, and malondialdehyde) in brain tissue. In addition, the EOF and EOP effectively activated mitochondrial functions by protecting the mitochondrial membrane potential, ATP, mitochondria-mediated protein (BAX and cytochrome c), and caspase 3/7 activities. The EOF and EOP also improved the cholinergic system (acetylcholinesterase and acetylcholine). Therefore, we suggest that onion could be used for management of Aβ-induced cognitive dysfunction.

This study was conducted to extend the understanding and knowledge by examining the effect of climacteric symptoms and the cognitive function on QoL(Quality of life) of middle aged women. This study was conducted from March 2nd to March 10th, 2014. The data was collected by self-report questionnaires from 204 middle aged women. There was a significantly positive correlation between the climacteric symptoms and cognitive function. A significantly negative correlation was observed between the climacteric symptoms and QoL. The climacteric symptoms were a direct predictor and an indirect predicator of QoL mediated by the cognitive function. The study suggests that nursing intervention is needed to manage the climacteric symptoms and cognitive function for improving the QoL of middle aged women.
The goal of this research is a visual and auditory tool development enabling designers to have the same emotional value with users in the process of user centered design. Through the research, we intend to show the aid measure for making cognitive gaps narrow between users and designer in the process of transforming and understanding the emotional needs as a verbal image. because In the business practice of design, most of tools and techniques for assessment and analysis of emotional needs are those used usually in the marketing fields. So the information generated and transformed from users to designers have a form of physical words. When the designer's understanding of the emotional needs is considered as a product mediated communication process, the morphologic and cognitive information gaps become obvious. This difference could be a false basis in designing with emotional user needs. So the alternative needs assessment sub-tools of visual and auditory information form was embodied mainly for designer's cognitive gaps and inter-cultural emotional needs assessment. As the method of embodiment, Firstly, adjectives related to emotion were classified in their cognitive dimension. Secondly, visual and auditory data were extracted, and then the relativity verified. Finally, the practicality and effectiveness were tested through the database generation. In view of the results so far achieved, 1. We could find being of the big information cognitive gaps in the verbal assessment of emotional needs between designers and users. 2. With the visual and auditory assessment tool, we could make the big cognitive gaps narrower than we expected. 3. Also, we could find the chance that the fidelity, recognition, and friendliness of design for emotional user needs would become better.
