The goal of this research was to understand the patterns of multidimensional engagement in MOOCs. An email with an online survey link was sent to enrollees in an MOOC course. The survey included 35 questions asking about engagement, teaching presence, and learning persistence. The items were validated in the literature, revised for the MOOC setting, reviewed by four professionals in the field of educational technology, and used in the study. A heterogeneous group of 170 individuals gathered through convenience sampling participated in the study. With cluster analysis of the engagement data, three groups were identified: Cluster1, 2, and 3. Cluster 1 scored high on behavioral, emotional, and cognitive engagement. Cluster 2 scored high on behavioral aspects but low on emotional and cognitive engagement. Cluster 3 scored low on behavioral and cognitive engagement but high on emotional aspects. The study addressed cluster-specific learner characteristics and differences in perceived teaching presence and learning persistence. Design strategies pertaining to each cluster were further discussed. These strategies may guide instructors and practitioners in the design and management of MOOCs and should be further validated through future studies.

Objective : The purpose of this study was to examine the level of the cognitive function, and to identify the influencing factors on cognitive function in women cancer patients receiving chemotherapy. This study attempted to provide basic data useful to development of nursing intervention and improve the quality of life in women cancer patients. Methods : As a cross-sectional descriptive study, women with receiving chemotherapy above one cycle were recruited. One hundred and twenty-five women cancer patients who met the study criteria agreed to participate in the study. The questionnaire set consisted of cognitive function, quality of life, depression, anxiety and information on demographic and clinical characteristics. Results : There was no statistically significant difference in clinical characteristics according to the cognitive function. The cognitive function was higher the more low age (F=9.937, p<.001), and the more high education level (F=12.332, p<.001). Multiple regression analysis showed the predictors were significantly related to cognitive function. age, education, and the number of chemotherapy explained 31.8% of the cognitive function. Conclusions : This result of this study provides basic information about factors influencing cognitive function, although study findings are insufficient in explaining related variables among women cancer patients. Even though women cancer patients were receiving chemotherapy, this study showed that the level of cognitive function was high. In order to receive better results and findings the period decreasing cognitive function, further studies are need to measure cognitive function according to the passage of time during or after chemotherapy.

Aviation safety issues have drawn much attention from the international community due to the growing demand for air travel. Although it is a widely accepted fact that human-related factors are closely linked to aviation safety, there is lack of understanding what roles those factors play in aviation, in the field of air traffic control in particular. It has been reported that the role of air traffic controllers significantly affects air safety. This review will discuss cognitive aspects of expertise in air traffic control including time perception, working memory, reasoning, perception, attention, scanning/vigilance, decision making, and planning with examples of how each aspect can be dealt with in performing air traffic control duties. The relevant studies in psychology have also been briefly reviewed in the interest of enhancing understanding of characteristics of air traffic control tasks and the related human factors. This review concludes with a call for more in-depth research into cognitive factors in air traffic control.

Consumers experience various cognitive and emotional contents of clothing through postpurchase process. These experiences may affect consumer satisfaction as well as brand attitude toward clothing products. The purpose of this study was to examine the effects of consumption experiences on the brand attitude toward clothing products. The research questions for accomplishing the purpose of this study were to investigate 1) the dimension of consumption experiences, 2) relationships among consumption experience, satisfaction and brand attitude toward clothing. The sample of this study was consisted of 431 females. The survey method, and factor analysis and regression were utilized for this study. The results were as follows; First, it was found out the consumption was composed of two dimensions such as cognitive and emotional experiences. According to the result of factor analysis, the cognitive experiences through consumption process were composed of 6 factors, that is, the suitability, fitness, utility/economy, sewing, deformation, and management. And emotional experiences were composed of 5 factors, that is, unpleasure, activeycomfort, inter-oriented pleasure, extra- oriented pleasure, tension. Also emotional experiences could be composed of two dimensions, that is, positive and negative emotion. The positive emotions were included pleasure and active/comfort. The negative emotions were included unpleasure and tension. Second, the result of path analysis showed that consumption experiences were related to satisfaction and brand attitude. A satisfaction influenced on brand attitude more strongly than others. And sewing, activejcomfort, extra-oriented pleasure out of cognitive and emotional experience factors affected to brand attitude directly. Satisfaction was also influenced by cognitive and emotional factors, and was the important mediator in forming brand attitude toward clothing through consumption experience. Above results imply that consumer experience multidimensional cognitive and emotional aspects of clothing through consumption process. The cognitive and emotional aspects consisting of consumption experiences, satisfaction, and brand attitude are interrelated causally. Therefore, experience related variables could be the antecedents of satisfaction and brand attitude. The satisfaction and positive emotion could be also important factors in brand attitude toward clothing.

An integrated framework of modeling the human operator cognitive behavior during nuclear power plant accident scenarios is presented. It incorporates both plant and operator models. The basic structure of the operator model is similar to that of existing cognitive models, however, this model differs from those existing ones largely in too aspects. First, using frame and membership function, the pattern matching behavior, which is identified as the dominant cognitive process of operators responding to an accident sequence, is explicitly implemented in this model. Second, the non-task-related human cognitive activities like effect of stress and cognitive biases such as confirmation bias and availability bias, are also considered. A computer code, OPEC is assembled to simulate this framework and is actually applied to an SGTR sequence, and the resultant simulated behaviors of operator are obtained.

Purpose: The purpose of this study was to examine cognitive functions, depression, and life satisfaction among the elderly receiving visiting nursing services. Methods: The subjects of this study consisted of 221 elderly individuals who were receiving visiting nursing services from a public health center located in Gyeonggi-do. The Mini-mental State Examination Korea version (MMSE-K), Geriatric Depression Scale-short form-Korea version (GDS-K), and Life Satisfaction Scale were utilized to determine cognitive functions, depression, and life satisfaction, Collected data was analyzed by the SPSS PC Win 12,0 program. Results: The prevalence of cognitive impairment (MMSE-K$\leq$24) was 86.4%, and the proportion of severe depression (GDS-K$\leq$10) was 22,6%, Older age, lower education, and low income were associated with cognitive impairment, and low education, no religion, and low income were associated with depression. Cognitive function negatively correlated with depression. Life satisfaction level was fairly low and was not associated with any variables. Conclusion: The high prevalence of cognitive impairment and low life satisfaction status were determined among low-income elderly who were registered at a visiting health care center. Thus, in the future at visiting health care services, efficient and various programs for the elderly should be tried, to improve cognitive functions and reduce depression. Additionally, consistent evaluation studies for those programs will be required.
