While online shopping has been increased expeditiously, a significant portion of purchasing intention has not been converted into actual purchasing behavior without delay in online space. This study investigates the factors causing a delay in online purchasing decision even after purchasing intention has been formed. It identifies the uncertainty variables (information, psychological, and preference uncertainties) related to consumer needs and the situational variables (time pressure and past purchase experience) surrounding the purchasing transaction. Furthermore, the need for cognitive closure is proposed to moderate the relationships between uncertainty/situational variables and the purchasing behavior. The results show that the uncertainties and situational factors significantly influence purchasing delay. Also, the need for cognitive closure indeed works as a moderator between the uncertainty variables and the purchasing behavior. Practical and academic implications of these findings are also discussed.

We aimed to provide evidences for developing non-pharmacological intervention in older adults with Mild Cognitive Impairment(MCI) by integrated literature review. The final 16 papers were selected as a result of an integrated literature analysis. All of them are focused on strengthening cognitive activities, while Korean studies have often merged emotional activities such as music therapy and laughter therapy rather than physical activities such as exercise therapy, international studies have combined physical activities rather than emotional activities. The effects of non-pharmacological intervention differed according to the outcome variables. The primary variables were cognitive function and depression, and secondary variables were found to have effects on physical function, activities of daily living (ADL), and self-efficacy. This study contributes to a multidisciplinary approach that can be applied in the clinical field through the development of various non-pharmaceutical intervention for the prevention of dementia in the older adults with MCI.

The purpose of this study was to investigate methodological and theoretical problems in measuring the acquisition of national identity of in-country and over-seas Korean adolescents. The subjects consisted of 574 incountry and overseas (Chinese, Russia and Japan) Korean adolescents (total 509), 15 to 25 years of age. Data were collected with the use of a questionaire, the Scale of National Identity. The results were that (1) the concept of national identity was organized on two dimensions (cognitive vs. sociocultural). The former consisted of 6 cognitive characteristics (uniqueness, sameness, continuity, acceptability, respectability and royalty). The sociocultural dimension consisted of the cognition of 7 sociocultural characteristics (history, norm, fraternity, symbol, consanguinity, Korean language and nationality). Except for consanguinity, there was a close relationship within each and between the 6 cognitive characteristics. Also there was a close relationship within each and between the 7 sociocultural characteristics of national identity. (2) Some demographic variables, such as age of respondents, place of birth and level of understanding of Korean language contributed to acquisition of national identity. (3) Among several demographic variables, nationality was the most explainable.

In non-face-to-face teaching-learning, a survey was conducted on 55 students in the department of chemistry education at university A on the variables (behavioral control, instructor-learner interaction, cognitive learning) affecting learning satisfaction and academic achievement. There were relatively large positive correlations between variables. The positive correlation between them was found to be the factors that influenced learning satisfaction and academic achievement in non-face-to-face teaching-learning. The average values of non-face-to-face teaching-learning for each variable were lower than the corresponding values of face-to-face teaching-learning, respectively. As a result of the perception survey on the detailed factors of each variable, negative responses were relatively high in factors such as 'concentration of behavior' in behavioral control, 'level-considered explanation' in instructor-learner interaction, and 'knowledge understanding' in cognitive learning.

This study was done to investigate the relationship of socioeconomic status and food intake to cognitive status of the older population. The subjects of this study consisted of 214 older persons aged 60 - 84 years. Interviews were conducted using the health-related habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food consumption-pattern and cognitive status of the subjects. The results of this study were as follows： Mean age of the subjects was 69.7${\pm}$7.4 years. The average cognitive function score of the subjects was 7.9${\pm}$2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and family type. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects that had a lower cognitive status score. These results have demonstrated that various socioeconomic variables and food intake pattern affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.

High school students' achievements in algorithmic problems, and figure-formatted and textual-formatted conceptual problems concerning stoichiometry, gaseous state, and solution, were measured by the Chemistry Problem Solving Ability Test. The relationships among the achievement scores in the three types of problems and cognitive variables such as logical thinking ability, mental capacity, and field dependence/field independence were examined. The portion of variance of explanation for each achievement score was also studied by a multiple regression analysis. The results showed that logical thinking ability was significantly correlated with the achievement score in the algorithmic problems, and accounted for the significant portion of the variance of the score. Mental capacity accounted for the significant portion of the variance of the score in the figure-formatted conceptual problems. Although field dependence/field independence was significantly correlated with all the achievement scores, it did not significantly account for any scores in multiple regression analyses. However, the magnitudes of correlation coefficients among the achievement scores were higher than those between the achievement scores and cognitive variables. The best predictor for each score was also found to be one of the other achievement scores. Educational implications are discussed.

A Korean standardized set of pictures has been called for as more and more studies utilized picture stimuli among memory and representation research. This article presents a Korean standardized set of pictures for studies probing the cognitive mechanisms that underlie picture and word processing or studies that simply utilize pictures stimuli. This norm provides 213 pictures, data on several variables such as name agreement, appropriateness of pictures. and familiarity. Previous data on such variables as frequency. category. and frequency within a category have been integrated 1 into this norm. Limitation, usage. and application of this set are discussed in terms of 1 implicit and explicit memory, and those variables mentioned previously.

This study aimed to confirm the positive impact of individual entrepreneurial orientation on entrepreneurial intentions and to investigate whether cognitive competency and social awareness of entrepreneurs serve as mediating variables in the relationship between individual entrepreneurial orientation and entrepreneurial intentions. The results of this study are as follows: Individual entrepreneurial orientation positively influenced entrepreneurial intentions, cognitive competency, and social awareness of entrepreneurs. Moreover, it was found that higher levels of cognitive competency and social awareness led to higher entrepreneurial intentions. Additionally, it was demonstrated that cognitive competency and social awareness of entrepreneurs had parallel mediating effects in the relationship between individual entrepreneurial orientation and entrepreneurial intentions. Based on these findings, this study provides theoretical foundations for research on the relationship between individual entrepreneurial orientation and entrepreneurial intentions, which have been relatively underexplored. Furthermore, by identifying cognitive competency and social awareness as mediating variables, this study opens avenues for academic expansion. Finally, the findings of this study can serve as practical groundwork related to individual entrepreneurial orientation.

The purpose of this study was to verify the effect on learning using YouTube. The relationship between expectations, cognitive attitudes, emotional attitudes, and reuse intentions was explored. The results are as follows. First, the factors affecting the intention to reuse YouTube were emotional attitude and expectation. cognitive attitude did not show any significant effect. Second, cognitive attitude and expectation agreement were significant variables in emotional attitude. cognitive attitude was identified as a major factor affecting emotional attitude. Third, expectation agreement was found to have a significant influence on cognitive attitude. Therefore, expectancy is an important factor in identifying cognitive attitudes. In particular, the satisfaction of expectations after experiencing a new technology or system, such as YouTube, affects the cognitive attitude. Finally, the main findings of this study were that cognitive attitude was not a variable affecting the intention to reuse YouTube. The reason for this is that YouTube is used as a medium of interest, and it is not used as a medium for searching the main data source for learning. Therefore, in order to activate YouTube learning, it is necessary to convert recognition into YouTube for learning rather than YouTube for play.

In this paper, we consider the problem of designing optimal sensing time and the minimization of energy consumption in the Cognitive radio Network. Trade-off between throughput and the sensing time are observed, and the equations are derived for the optimal choice of design variables. In this paper, we also look at the optimization problem involving all the design parameters together. The advantages of the proposed scheme for the spectrum sensing and access process are shown through simulation.
