Purpose: The purpose of this study was to test the mediating effect of psychological distress in the relationship between chemotherapy related cognitive impairment (CRCI) and quality of life (QOL) in people with cancer. Methods: A purposive sample of 130 patients undergoing chemotherapy was recruited for the cross-sectional survey design. Data were collected from November 2014 to June 2015. The instruments were K-MMSE (Korean Mini-Mental State Examination), Everyday Cognition (ECog), Hospital Anxiety Depression Scale (HADS), and Functional Assessment of Cancer Therapy-General (FACT-G). Data were analyzed using descriptive statistics, correlation, and multiple regression using Baron and Kenny steps for mediation. Results: The mean score for objective cognitive function was 27.95 and 69.32 for perceived cognitive decline. Overall quality of life was 91.74. The mean score was 17.52 for psychological distress. The prevalence was 56.2% for anxiety and 63.1% for depression, and 20.0% for CRCI. There were significant correlations among the variables, objective cognitive function and self-reported cognitive decline, psychological distress, and quality of life. Psychological distress was directly affected by CRCI. ($R^2=29%$). QOL was directly affected by CRCI. Psychological distress and CRCI effected QOL ($R^2=43%$). Psychological distress had a partial mediating effect (${\beta}=-.56$, p <.001) in the relationship between self-reported cognitive decline and quality of life (Sobel test: Z= -5.08, p <.001). Conclusion: Based on the findings of this study, nursing intervention programs focusing on managing cognitive decline, and decreasing psychological distress are highly recommended to improve quality of life in cancer patients.

There is no universally agreed classification of human error, nor is there one in prospect. Thus, a taxonomy is usually made for a specific purpose. To seek the types of human errors in the environment of man-machine interface under the railway industry, we develop a cognitive information processing model incorporating the human's mental states. Using the model, this study investigates the types of human errors about the railway workers. Thus, a survey is conducted for railway safety personnel-locomotive engineers, station employees, and train commanders- in Korean railway company. Through the survey that is designed to investigate four types of human errors from the Questionnaires composed of thirty Questions, we analyze the types of human errors related to railway safety according to affiliated offices, operation shifts, age, and working years. Finally, from the insights of the results some guidelines for the railway safety management are presented.

Purpose: The purpose of the study was to examine the relationships between cognitive coping, hope, depression, and life satisfaction of hemodialysis patients based on the stress-coping model. Methods: For this cross-sectional survey, 142 participants were recruited from 10 local clinics in Seoul and Daegu during 2012-2013. The data collection instruments included the Cognitive Emotion Regulation Questionnaire, the Herth Hope Index, the Hospital Anxiety and Depression Scale, and the Satisfaction with Life Scale. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and stepwise multiple regression. Results: The cognitive coping scores were significantly related to hope, depression, and life satisfaction. The coping strategies explained 80%, 37%, and 38% of the variances in hope, depression, and life satisfaction, respectively. The most powerful coping strategy was positive refocusing, explaining 73% in hope, 25% in depression, and 25% in life satisfaction. Conclusion: The results of the study indicate that cognitive coping plays an essential role for psychological adaptation of hemodialysis patients. Thus, interventions integrating positive refocusing would help instilling hope of hemodialysis patients in Korea.

The present research aims to identify the relationship between trust and distrust in an online business environment. To clarify the concepts, cognitive-affective personality system theory was introduced, through which five types of psychological units were proposed. In developing the research model based on the theory, technical effectiveness of the system and content truthfulness of the website were selected as two key stimuli for the coding process of online users. Trust and distrust were selected as mediating factors that generate consequent behaviors. Finally, purchase intention served as a final dependent variable. Assuming that trust and distrust emerge in psychologically different stages, this study hypothesized the mutual causal relationship between trust and distrust, indicating that the relationship will be determined by their contextual emphasis on each dimension. To validate, a survey was conducted with 307 online shopping mall users. Results show that stimuli were more significantly associated with trust. Trust is therefore a more cognitive construct than distrust, and the path from trust to distrust is stronger than that from distrust to trust. This finding implies that the cognitive aspect of trust is stronger than that of distrust. Distrust is rather more affectively emerging than trust.

In this study, the relationships among learners' cognitive variables, motivational variables, and conceptual understandings in learning with analogy were investigated. The instruments regarding analogical reasoning ability, field dependence-independence, mental capacity, and logical thinking ability were administered. Some subtests (self-efficacy, expectancy, self-concept of ability, and value) of the Patterns of Adaptive Learning Survey were administered. After students learned with a worksheet that included analogy, a conception test regarding 'stoichiometry that included limiting reagent' was also administered. It was found that learners' conceptual understandings were significantly correlated with the logical thinking ability and the field dependence-independence among the cognitive variables, and the self-efficacy and the self-concept of ability among the motivational variables. The multiple regression analysis of the cognitive variables on conceptual understandings revealed that the logical thinking ability was the most significant predictor. The field dependence-independence also had predictive power. In the analysis of the motivational variables, the self concept of ability was the only significant predictor.

Globalization has led to a dramatic increase in intercultural service encounters between services providers and customers from diverse cultural backgrounds. This paper explores the causal relationship between service employees‟ cultural intelligence and adaptive sales behavior in intercultural service encounters, and the mediating effect of cognitive and emotional empathy on this relationship. A quantitative survey methodology was utilized to collect data on 341 salespeople at duty-free shops located on Jeju Island, Korea. Data analysis was conducted using SPSS 18 and Amos 18. The results show that cultural intelligence has a significant impact on cognitive empathy, emotional empathy, and adaptive sales behavior. Cognitive empathy has a positive impact on adaptive sales behavior, whereas the relationship between emotional empathy and adaptive sales behavior is not significant. Additionally, cognitive empathy mediates the relationship of cultural intelligence and adaptive sales behavior. This study has useful managerial implications for employee selection, training, and development in service firms engaged in intercultural service encounters. This study extends prior research on intercultural service encounters by exploring the direct impact of cultural intelligence on intercultural adaptation and the mediating effect of empathy, suggesting the presence of a cognitive mechanism that plays a key role in the impact of cultural intelligence on adaptive sales behavior.

Purpose: This study developed a cognitive behavioral therapy program aimed at altering the physical condition, emotions, and behaviors of fibromyalgia patients, and confirmed the program's clinical applicability. The program was developed by analyzing previous studies conducting in-depth interviews with fibromyalgia patients, drawing on cognitive behavior theory to establish the program contents, recruiting experts to test its validity, and conducting a preliminary survey. Methods: To confirm the program's effect, this study used a randomized controlled trial design. The participants were outpatients diagnosed with fibromyalgia in Dong-A University Hospital, Busan. The 30 patients in the experimental group took part in the program, which comprised 8 sessions (90 to 120 minutes) based on cognitive behavior theory, delivered over 8 weeks. Hypothesis testing was carried out using the repeated measures ANOVA. Results: The analysis revealed significant differences between the experimental and control groups in positive automatic thoughts, pain, fatigue, depression, and interpersonal relationships. However, there was no significant difference between the groups in terms of sleep disorders and negative automatic thoughts. Conclusion: This program is a positive effect on physical condition, emotions, and behaviors. It is thus expected to be used to help fibromyalgia patients improve their disease conditions.
