Mathematics is among the most important subjects in the middle school curriculum, yet the most hated subjects by students. The present study investigated the role of perceived executive functioning on the middle school student's mathematics achievement, after controlling for other psychological factors. Results showed that the students levels of executive functioning was predictive of their mathematics achievement test scores, even after motivational and attitude variables were controlled. The impact of the executive functioning was especially noticeable for the low achievers. On the other hand, for those whose scores were high, biological variables were the only significant predictors of their scores. The results of the present study imply that the intervention programs for improving mathematics achievement of middle school students should consider the different effect of cognitive and psychological factors on their achievements.

Purpose: The purpose of this study was to identify the gender differences in the cognitive function and nutritional status among elderly people living in the community. Methods: This study used data from the 2014 National Survey on the Elderly and focused on 10,054 respondents who answered that they did not have dementia. The Korean version of Mini-Mental State Examination for Dementia Screening and the Nutrition Screening Initiative were used. IBM SPSS Statistics 23.0 was used to conduct statistical analyses. Results: The cognitive function score was 25.30 for men, which was higher than for women. The percentage of subjects who showed cognitive decline was 25.5% for males and 50.2% for females, which was statistically significant (p<.001). There were statistically significant differences in the nutritional status between males and females (p<.001). There was a statistically significant negative correlation between the cognitive function and nutritional status in both men and women (p<.001, p<.001). Conclusion: These results showed that the intervention to maintain cognitive functioning should be provided to elderly women with a low education level or high number of chronic diseases and medication, and an intervention to prevent the cognitive decline of the elderly should include nutritional management for health and function maintenance.

Purpose: The purpose of this study was to assess the relationship between menopausal symptoms and decline in cognitive functioning of menopausal women with mediating effects of health promoting behavior. Methods: Using a convenience sampling, 140 menopausal women were recruited for the cross-sectional survey. Data were collected by using the Menopause Rating Scale, Health Promoting Lifestyle Profile, Everyday Cognition, and Korean Mini-Mental State Examination. Results: The mean scores for menopausal symptoms, health promotion behavior, and subjective cognitive decline were 14.40, 153.79, and 67.40 respectively. Health promotion behavior was directly affected by menopausal symptom ($R^2=8%$). Cognitive decline was directly affected by menopausal symptom ($R^2=11%$). Menopausal symptom (${\beta}=.33$, p<.001) and health promotion behavior (${\beta}=.21$, p=.014) were found to be predictive factors in subjective cognitive decline and explained 14%. Health promotion behavior had a partial mediating effect in the relationship between menopausal symptom and perceived cognitive decline (Sobel test: Z=2.05, p=.040). Conclusion: Based on the findings of this study, developing nursing intervention programs focusing on decreasing menopausal symptoms and encouraging health promotion behavior are recommended to improve cognitive decline in menopausal women.

Higher cognitive functions refer to the highest level of human intellectual functioning, including concept formation, reasoning, and executive functions. The executive functions can be conceptualized as having four components : volition, planning, purposive action, and effective performance. Because higher cognitive functions represent the most advanced stages of intellectual development, they are often highly susceptible to the effects of brain injuries and mental disorders. The ability to perform effectively within the environment is determined in large part by an individual's adequacy in performing such higher-order functions. Especially executive functions are necessary for appropriate, socially responsible, and effectively self-serving adult conduct. Threfore, an assessment of the psychiatric patient's performance in these areas will provide useful diagnostic information, as well as information concerning social and vocational prognosis.

Vascular dementia is a very frequent form of dementia. Debates over classification and diagnostic criteria, and controversy over identifiable treatment targets will continue until distinct pathophysiological mechanism of vascular dementia is found. Clinical diagnostic criteria are sufficiently strong to be useful for clinical trials, but need further refinement. Cognitive changes in vascular dementia are more variable than other disorders, and are dependent on the vascular pathology. Accurate diagnosis of vascular dementia is known to need the presence of reliable cerebrovascular disease on brain imaging. Although it seems obvious that cerebrovascular disease causes pathological damage and impaired cognition, it is very difficult to find the accurate contribution of cerebrovascular pathology to cognitive decline. Most studies have shown a small but significant benefit of cholinesterase inhibitors on cognition, the significance of this effect has been slight and benefits on global functioning, activities of daily living, and behaviour have not been consistently reported. Management of vascular dementia should focus on identifying and managing vascular risk factors.

In contrast with Zelazo and Frye (1997) who argued that preschool children lack the conscious representation and executive functioning needed to solve problems based on conflicting rules, Bilaystok (1999) identified analysis(representation) and control(selective attention) as components of language processing and has shown that control develops earlier in bilingual than in monolingual children. This study investigated the effects of bilingualism on children's cognitive ability and language development by comparing Korean- Chinese bilingual with Chinese monolingual children in Yanji. Sixty children 3 to 5 years of age in each of the bilingual and the monolingual groups in Yanji, China participated in ths study. Results showed that bilingual were more advanced than monolingual children in solving problems requiring a high level of control, confirming Bialystok's(1999) results.

Objectives : The purpose of this pilot study was to investigate the potential clinical benefits a single group session of cognitive behavioral therapy in the treatment of patients with panic disorder. Methods : The study participants were 18 patients (14 males, 4 females; mean age=38.9 years), all of whom were assessed as meeting the DSM-IV-TR criteria for panic disorder. All participants attended one two-hour session of structured group cognitive behavioral therapy (CBT). Clinical symptoms was assessed before and eight weeks after the single therapy session using the Panic Disorder Severity Scale (PDSS). Results : Eight weeks after a single session of group CBT significant improvements were found in panic attack frequency, distress during panic attacks, severity of anticipatory anxiety, agoraphobic fear/avoidance, panic-related sensation fear/avoidance, impairment in work functioning, impairment in social functioning. Conclusions : One session of group CBT appears to be an effective treatment of panic disorder by reducing the severity of all symptoms assessed on the PDSS. An attempt should be made to replicate the findings of this pilot study in a larger and controlled, comparative clinical trial.

This study examined if the effect of family functioning on preschoolers' school readiness can be mediated by mothers' affective parenting and preschoolers' self-regulation in the year before children enter elementary school. This study analyzed the 7^th year data of panel study of Korean children collected by the Korean Institute of Child Care and Education. Statistical analysis included 1,513 pairs of 6-year-old children and mothers. Descriptive statistics analysis, correlation analysis, structural equation modeling, and bootstrapping analysis were conducted using SPSS 22 and Amos 20. The primary findings were as follows. First, the sub-factors of preschoolers' school readiness composed of children's social and emotional development, approach to learning, cognitive development and general knowledge, and communication were positively correlated with family functioning, mothers' affective parenting, and preschoolers' self-regulation. Second, the result of structural equation modeling showed that the indirect paths from family functioning to preschoolers' school readiness through mothers' affective parenting and preschoolers' self-regulation were significant, while the direct path was insignificant. Third, bootstrapping analysis showed that mothers' affective parenting and preschoolers' self-regulation fully mediated the relationship between family functioning and preschoolers' self-regulation. The findings provide the grounds for families and parents with preschool aged children to implement effective support practices to maintain a functional family system that can promote preschoolers' school readiness.

Objectives: The authors intended to evaluate long-term outcome of group cognitive behavioral therapy(GCBT) for panic disorder and examined the variables to predict high end-state functioning in 12 months follow-up. Methods: 236 patients meeting DSM-IV criteria for panic disorder were assessed by STAI, ASI, BDI, BSQ, PBQ, ACQ at pre & post treatment, and were asked about the frequency of panic attacks during recent one month. We executed stepwise discriminant analysis on the clinical variables at pre treatment assessment to find the variables for discriminating between high end-state function(HES) and low end-state function(LES). Results: After GCBT, 82.6% of panic patients maintained high end-state functioning at 12 months follow-up. The results of discriminant analysis showed that BDI and BSQ at pre treatment assessment were significant variables to predict end-state functioning at 12 months follow-up. The hit ratio of discriminant analysis was 69.2%. Conclusion: These results suggest that the therapeutic effect of GCBT can be maintained through 12 months. Especially, it is likely that patients who were less depressed and who had less experienced the fear of physical symptoms at pre-treatment can maintain HES.

This study involved the effects of home-visit program with cognitive-stimulating activities on cognitive function and memory self-efficacy of an elderly with dementia special rating(5rates). The study was conducted from February 11 to April 26, 2019 using a 65-year old woman residing in G Metropolitan City. The individual subject study used an A-B-A design. The subject performed activities that required thinking and resolving in order to stimulate both her body and cognition. The activities chosen were easily accessible to those having a form of mild dementia, rates 5 dementia special rating, and repetitively stimulated the subject's intellectual capacity in an attempt to increase her degraded cognitive functioning. Specifically, the activities exercised both short-term memory and recollection using familiar letters, numbers, and bodily movements frequently encountered in daily life. The program positively affected the subject's memory and concentration. In addition, the program was found to be feasible for home use by those with mild dementia, obviating the need to travel to a location like a welfare center. The author presents specific activities for stimulating cognition that can effectively intervene to positively influence the cognitive functioning and memory of those with rates 5 dementia special rating.
