Children likes to play and learn by playing at anywhere as a psychological trait. Children's museum is designed for limited age of 'children,' they learn more actively by playing at the museum with interactive display. In this paper, we analyze Movement of Based on the Psychological Characteristics of Children and Analysis of Preferred Experience of Children's Museum according to Piaget's cognitive development process. It is significant study to investigate user's needs space proposal by grasping user's mentality. After itinerary tracking, we found children's preferred and non-preferred experience displays and as a result, we divided children's Museums into three types, M museum is represented by preoperational period, called 'Go around play' type ; Y museum is represented by 'concrete operational period', called 'Smart road play' type ; and H museum is represented by 'formal operational period' called 'Open search play' type. The conclusions are children's cognitive development stages depending on the age discrimination that the development of play, and preferred plays are different by children cognitive development process. In order to take advantage of children playing in the children's museum by taking into account the developmental aspects will have to be designed. Efficient for viewing by age should be different on the basis. This study has shown that, when planning a children's museum, Planners should discriminate the movements of children and analysis of preferred experience of children's museum according to three museum types friendly to children's cognitive development process.

Objectives: The aims of this study were to know the prevalence of cognitive disorders in patients with thyroid cancer, and identify related variables to them. Methods: Subjects were consisted of fourty-two patients with thyroid cancer, who were admitted for radioiodine ablative therapy at 6-12 months after total thyroidectomy. The data were obtained from interviews about history and assessments of depression and cognitive function(Korean Version of the Montreal Cognitive Assessment, MoCA-K). Results: 1) Among subjects, those with below 22 of total score of the MoCA-K were twenty-one(50.0%). 2) Upon age, education, Pre-radioiodine therapy thyroid stimulating hormone(TSH), there were statistically significant difference between subgroup with above 23 of the total MoCA-K score and those below 22. 3) The total scores of the MoCA-K in subjects had significant correlation with age, education, comorbidity, Pre-radioiodine therapy TSH, total score of the HDRS-17. Conclusions: Cognitive disorders were more prevalent among patients with thyroid cancer before radioiodine therapy. Therefore, further study should be needed to clarify the mechanism for the cognitive disorders in thyroid cancer. Furthermore, physicians should pay attention to the cognitive function and prepare preventative measures for cognitive disorder during management of thyroid cancer.

For the purpose of promotion of mental health in the rural elderly, the author surveyed 558 elderlies aged 60 years or more, and assessed the prevalence rates of depression and cognitive impairment by using self-rating depression scale of Zung (SDS) and the Korean version of mini-mental state examination (MMSEK). Also the association between depression or cognitive function and socio-environmental factors were investigated. The major findings were as follows ; 1. The prevalence rates of severe depression and cognitive impairment were 20.9% and 14.9% in all the elderly of both sexes, respectively. 2. The rates of depression and cognitive impairment increased with increasing age in both sex groups. The mean scores of SDS increased and the mean scores of MMSEK decreased significantly among them (p<0.01). 3. Those being female, widows or widowers, and those having low levels of physical activity, showed significantly high the mean scores of depression and had significantly low the mean scores of cognitive impairment (p<0.01). 4. The depression scores relating to decreased libido, confusion, psychomotor retardation, hopelessness and indecisiveness were relatively high in both sexes. 5. All the items of mini-mental state examination were significantly correlated with depression. 6. In stepwise multiple regression analysis on depression, MMSEK, level of physical activity, chronic disease, marital status and family income were selected as highly correlated variables, and the $R^2$-value for these variables was 33.7%. 7. In stepwise multiple regression analysis on cognitive function, level of physical activity, age, depression, sex and marital status were selected as highly correlated variables, and the $R^2$-value for these variables was 62.6%. The depression and cognitive impairment of the elderly were positively correlated with nearly all sociodemographic variables.

Background & objectives: Cognitive function decline is a main factor influencing the overall life of the elderly and places a burden of society. The aime of this study was to investigate the risk factors of cognitive function decline of elderly living alone and living with a spouse. Methods: This study used the Korean Longitudinal Study of Ageing from 2014 to 2018. 243 older adults who lived alone and 1,155 lived with a spouse with the Korean version of Mini Mental State Examination scores in normal range at the time of 2014 were included in the analysis. Logistic regression analysis was conducted to determine the difference of risk factors affecting cognitive function decline between in elderly living alone and elderly living with a spouse. Results: Cognitive function decline incidence rate of elderly living alone was 30.5% and the elderly living with a spouse showed 23.0%. According to the results of logistic regression analysis, the risk factors of cognitive function decline in the elderly living alone was age and residential area, while in the elderly living with a spouse were age, education level, social networks, and depression. Conclusions: The factors that affect the cognitive function decline of the elderly living alone and the elderly living with a spouse were different. Accordingly, other measures to prevent cognitive decline are necessary.

Purpose : This study aimed to present normative data and cut-off points for older Korean adults completing the Montreal Cognitive Assessment - Korean (MoCA-K), which is used as a screening test for mild cognitive impairment in Korea. Methods : A total of 195 healthy adults ≥60 years were recruited. All participants completed the MoCA-K and the Korean - Mini-Mental State Examination (MMSE-K) to assess their cognitive function. Participants were divided into six groups based on their age: 60-64 years, 65~69 years, 70~74 years, 75~79 years, 80~84 years, and 85~89 years. Results : The results revealed that MoCA-K score decreased significantly with age (mean score ± standard deviation [SD]; 27.63±2.80 in subjects aged 60~64 years; 27.00±2.39 in subjects aged 65~69 years; 24.94±2.96 in subjects aged 70~74 years; 24.74±3.37 in subjects aged 75~79 years; 22.59±4.72 in subjects aged 80~84 years; and 18.83±5.38 in subjects aged 85~89 years; p<.001). Additionally, MoCA-K score also increased significantly with educational level (mean score±standard deviation [SD]; 19.95±4.78 in no formal education group; 24.95±2.22 in elementary school graduated group; 26.35±2.72 in middle school graduated group; 28.32±1.36 in high school graduated group; and 28.50±1.51 in more than college graduated group; p<.001). The optimal cut-off points were 24/25 for 60~69 years old group, 21/22 for 70~79 years old group, 17/18 for 80~84 years old group, and 13/14 for 85~89 years old group. The optimal cut-off points were 15/16 for individuals who were illiterate, 22/23 for individuals with 6 years of education, 22/24 for individuals with 9 years of education, and 26/27 for individuals with 12 or more years of education. Conclusions : This study presents normative data and cut-off points for the MoCA-K in older Korean adults. This data will facilitate more accurate detection and follow-up of the risk of mild cognitive impairment in this population, taking into consideration age and education. Future studies are required that should focus on the cut-off score on the level of education according to age.

Cognitive impairment associated with childhood-onset epilepsy is an important consequence in the developing brain owing to its negative effects on neurodevelopmental and social outcomes. While the cause of cognitive impairment in epilepsy appears to be multifactorial, epilepsy-related factors such as type of epilepsy and underlying etiology, age at onset, frequency of seizures, duration of epilepsy, and its treatment are considered important. In recent studies, antecedent cognitive impairment before the first recognized seizure and microstructural and functional alteration of the brain at onset of epilepsy suggest the presence of a common neurobiological mechanism between epilepsy and cognitive comorbidity. However, the overall impact of cognitive comorbidity in children with epilepsy and the independent contribution of each of these factors to cognitive impairment have not been clearly delineated. This review article focuses on the significant contributors to cognitive impairment in children with epilepsy.

This study researches age of discretion and lifestyles for aged women consumers and examines their social and psychologically recognized age of discretion and the difference in shopping orientation on fashion. Also it is purposed to support implications for marketing strategy on fashion market for the aged. A survey was carried out regarding the consumers of the new elderly generation aged 55 and above. 561 respondents were surveyed, residing in Seoul and Metropolitan areas. Factor analysis, Cronbach's ${\alpha}$, K-average community and multivariate analysis, multi-recurrence and crossing analysis($X^2$ verified) were used for statistical analysis. In conclusion, first, people in their 70s to 80s perceive their age 20 to 30 years younger than their real age. Second, appearance-oriented and high technology-oriented were the most highlighted lifestyles as to the study of the vital statistical, related to the lifestyle in correspondence to the real-age and the cognitive age. Third, people who feel older than they actually are in terms of shopping orientation were less likely to shop depending on their mood. Throughout the results, there is no doubt that people in the elderly generation is a main target within marketing trends in the elderly generation industry. A research based on comparison between the male and the female consumers in the elderly generation is considered to be very meaningful.
