Purpose: This study was conducted to evaluate cognitive ability in preschoolers born prematurely and to investigate related factors. Methods: A prospective, longitudinal study was conducted with 64 children at 5-6 years of corrected age (CA) (second follow-up) among 76 children who had been assessed at 2.0~3.5 years of CA (first follow-up) from a sample of 343 preterm infants born from 2008 to 2010. To evaluate each child's cognitive ability, during a home visit, we used the Kaufman Assessment Battery for Children-II (KABC-II) at the second follow-up. To explore factors related to cognitive ability, we measured children's hemoglobin level at the second follow-up and used the data collected in our previous study, including the Bayley Scale of Infant Development-II (BSID-II) at the first follow-up. Results: The mean total KABC-II quotient was $117.0{\pm}14.4$. The 5-minute Apgar score (${\beta}=.29$, p=.006), hemoglobin level (${\beta}=.22$, p=.032), and the mental development index quotient of the BSID-II (${\beta}=.51$, p<.001) were statistically significant predictors of the KABC-II quotient in multiple linear regression analysis. Conclusion: The cognitive function of young children born prematurely was influenced by early neurodevelopment and factors reflecting their health status, such as anemia and a low 5-minute Apgar score.

Purpose: The purpose of this study was to identify personal, contextual, and cognitive factors influencing the career preparation behavior of Korean nursing students. In this study, an examination was done of the fitness of a path model for the relationship among these factors based on the social cognitive career theory. Methods: The participants were 413 nursing students in South Korea. Data were collected using self-report questionnaires that included self-esteem, social support, self-efficacy, outcome expectation, career decision level, and career preparation behavior. Data were analyzed using descriptive statistics, Pearson correlation analysis, and path analysis. Results: The factors influencing career preparation behavior were self-efficacy, career decision level, self-esteem, outcome expectation, and social support. The factors influencing career decision level were self-efficacy, outcome expectation, self-esteem, and social support. Conclusion: The findings indicate that self-efficacy is an important factor influencing the career behavior of Korean nursing students. Nurse educators should consider personal, contextual, and cognitive factors of nursing students and develop systemic career guidance programs to help nursing students' career preparation behavior.

Purpose: This study aimed to identify factors affecting subjective cognitive decline (SCD) in men and women. Methods: This study was conducted based on data from the 2021 Korea Community Health Survey, and targeted a total of 80,026 men and 98,753 women aged 40 or older who responded to the SCD assessment. Multivariate logistic regression analysis using a complex sample was performed to identify factors influencing SCD. Results: Of the participants, 19,438 (22.7%) men and 30,826 (29.9%) women in the community reported SCD. Significant factors that influence SCD in both groups were age, education level, subjective health status, and depressive symptoms, and the strongest risk factor was depressive symptoms. Compared to women, men's monthly income, flexibility exercise, hypertension, and diabetes mellitus were found to be significant factors on SCD and Healthcare services affected SCD only in women. Medical services affected SCD only in women. Conclusions: When planning and providing intervention programs for cognitive function, it is necessary to reflect differences in factors associated with SCD according to sex.

This paper reports an investigation of problem solving activities of students at university level students. The study focused on the cognitive-metacognitive and affective activities appeared in problem solving process. The cognitive-metacognitive framework was used to analyzed and categorize the written response and free response of interviews probing the students\\` cognitive-metacognitive activities. Affective factors were assessed by administering the problem solving survey (Carlson, The emergence of students\\` problem solving behavior, 1999). This study provide an insight for the design of problem solving instruction by identifying cognitive, metacognitive and affective characteristics of the students\\` problem solving behaviors. The results report that the metacognitive factor were significantly related to problem solving performance interacting with both cognitive and affective factors.

Objectives: Study purpose was to investigate perception on diet, diet problems and related factors among young adult women using focus group interviews (FGI) based on the Social Cognitive Theory (SCT). Methods: Eight groups of FGI were conducted with 47 female undergraduate or graduate students. Guide for FGI included questions regarding perception on optimal diet, diet problems and cognitive, behavioral, and environmental factors of SCT. FGI were video, audio-taped, transcribed and analyzed by themes and sub-themes. Results: Subjects showed irregular eating habits (skipping breakfast, irregular meal time) and selection of unhealthy foods as the main diet problems. Regarding cognitive factors related to optimal diet, subjects mentioned positive outcome expectations (e.g., health promotion, skin health, improvement in eating habits, etc.) and negative outcome expectations (e.g., annoying, hungry, expensive, taste). Factors that promoted optimal diet were mainly received from information from mobile or internet and access to menu or recipes. Factors that prevented optimal diet included influence from friends, lack of time and cooking skills. Behavioral factors for optimal diet included behavioral capability regarding snacks, healthy eating and smart food selection. Subjects mentioned mass media (mobile, internet, TV) as the influential physical environment, and significant others (parents, friends, grandparents) as the influential social environment in optimal diet. For education topics, subjects wanted to learn about healthy meals, basic nutrition, disease and nutrition, and weight control. They wanted to learn those aspects by using mobile or internet, lectures (cooking classes), campaign and events. Conclusions: Study results might be used for planning education regarding optimal diet for young adult women. Education programs need to focus on increasing positive outcome expectations (e.g., health) and behavioral capability for healthy eating and food selection, reducing negative outcome expectations (e.g., cost, taste) and barriers, making supportive environments for optimal diet, and incorporating topics and methods found in this study.

The purpose of this study is to propose cognitive ecological effects of fractal patterns in space design. This study investigated the perception and cognition problems regarding landscape patterns showing fractal properties from the cognitive perspective instead of the traditional speculative approach. In particular, the researcher has verified that fractal geometry theory and fractal pattern concept provide insight in space aesthetic values and cognitive effects. Research results are as follows. First, most environmentally-friendly fractal urban forms provide cognitive connectivity. In particular, this space provides a positive emotional response and preference to humans and displays self-organized complexity. This study found that such complexity of space form has characteristics corresponding to parallel cognitive structures of the human brain. Simultaneously, the researcher suggests that the fractal landscape pattern is an alternative for stiff and homogenized modern space. Second, fractal patterns provide hierarchical connectivity within the brain through continuous difference and repetition. In particular, self-similarities of fractal patterns administer significant visual grouping and coherence in human perception. It can be determined whether scaling coherence facilitates easier organization in cognitive organization. Third, fractal patterns in space design provide the basic method for achieving the connection between concept, construction, and urban factors. As a result, the researcher has suggested that scale distribution of geometrical factors, such as fractal patterns, an be a design method to connect various space typologies.

Purpose: The purpose of this study was to find out the degree of cognitive function among the elderly and to confirm its correlated factors. Methods: The subjects consisted of 392 elderly people over the age 65 who were living in Busan. Data were collected by the interview method, using a structured questionnaire and the K-MMSE scale. Results: The average points of the elderly's cognitive functions measured by K-MMSE were 23.76(${\pm}4.02$). With the cut-off point for cognitive impairment set as 24 points below using K-MMSE scale, 38.8% of the subjects have cognitive impairments. Among the variables related to cognitive functions, literacy showed the highest correlation with cognitive function(${\beta}=.330$, t=7.249, p<.001), followed in order by educational level, age, depression level, attendance of elderly's college, and religious activity. The total explanatory power of these variables is 36%. Conclusion: In order to prevent cognitive impairment among the elderly, elderly people have to maintain social relationships continuously, and expand the social network by participating in the related programs. Some efforts to prevent the occurrence of depression and to stimulate patients' brain activity need to be recommended.

This study was conducted to find sensitive indicator of food intake and specific food group related to cognitive function and to analyze the pathway among factors affecting food intake and cognitive function of the aged. 179 people over 50 years old were investigated and all the data were analyzed by SPSS 10.0 package. Food frequency was more sensitive indicator to show the relationship between food intake and cognitive function of the aged than the numbers of standard amount of food eaten. Consumption of grains and starch, meat, fish, eggs and beans were strongly related to cognitive function of the aged and intake of vegetables and fruits also have relationship with it. Moreover, the more frequent eating the carbohydrate and the protein, the higher the cognitive level of the aged. Age, education period, income, blood pressure, duration after retirement, frequency of physical activity and BMI were correlated with food intake and cognitive function of the aged. Among them, age and frequency of physical activity were most strongly correlated with food intake, and education period with cognitive function of them. This investigation shows that more stable intake of carbohydrate and protein containing foods need to be supplied to low income aged and the importance of physical activity of the aged must be emphasized with food intake for better life of the aged.
