  • In a large number of literature on of inspection tasks, one of the most consistent findings is the existence of large and consistent differences among inspectors. It is possible that the individual difference is described by the difference of cognitive skills, because cognitive skills are required more than manual skills in inspection tasks. Therefore, a set of cognitive factors in human information processing may underly human performance in inspection tasks. In this study, a cognitive skill was described as the relative importance of the cognitive factors involved. A hierarchical task analysis and a fuzzy hierarchical analysis were used to represent how the importance of cognitive factors contribute to inspection performance. An experiment was conducted using the computer simulations of PCB inspection tasks. The results revealed that the subject group with better performance showed the importance weights of cognitive factors in the following rank; (attention, perception, judgement, classification, recognition)<(detection)$\ll$(memory). The results of the experiment can serve as a selection criterion for efficient inspection performance and the information of skilled learning for an inspection training program. The usefullness of a hierarchical task analysis and a fuzzy hierarchical task analysis for the analysis of cognitive tasks are also confirmed.

  • The purpose of this study was to investigate the cognitive differences among the aged who have different living conditions. 91 free-meal receivers and 86 people with stable lives were asked about their living conditions and cognitive function by using K-MMSE. All data were analyzed by SPSS 10.0 package. Free meal receivers had poorer socioeconomic status than the subjects who had stable lives. Cognitive function of free meal receivers was lower than the people with stable lives in the most cognitive factors. Especially age of 50 to 64, pre-aged group, who had been receiving free meals, showed lowest cognitive level than the other age groups. Among 7 cognitive factors, there was the greatest difference in attention and calculation between 2 groups. Percentage of 'conclusive dementia' among the free meal receivers was statistically higher than the people with stable lives and that of 'conclusively normal' was statistically lower in free meal receivers comparing with the people with stable lives. Moreover, socioeconomic factors like income, former job, marital status, housing and education, blood pressure and physical activity were significantly related to the subject's cognitive function.

  • Purpose. The purpose of this study was to survey the prevalence rate of cognitive impairments and to identify the factors influencing cognitive impairment in the elderly in rural communities of Jeju Province. Methods. 590 elderly in 6 rural communities of Jeju Province were interviewed, using a questionnaire consisting of sociodemographic characteristics, health behavior, quality of life, and MMSE-K Results. Prevalence of cognitive impairment was 33.1 % (39.1 % of females, 16.76% of males). Prevalence of dementia was 12.4% (16.3% of females, 2.87% of males). Factors related to cognitive impairment were age, sex, education, standard of living, employment status, and subjective health state. Conclusions. In community health care for the elderly, factors relating to cognitive impairment have to be considered. When planning community health care, priority should be given to the elderly; who need care but live alone; who lack social support; who have a low standard of living; who experience discomfort in the activities of daily living; who believe they are not in a good state of health; or whose life satisfaction is low.

  • The tourism industry is influenced by a large number of factors that affect the development scenarios of the tourism in different ways. At the same time, tourism is an important component of the national economy of any state, forms its image, investment attractiveness, is a source of income and a stimulus for business development. The aim of the article is to conduct an empirical study to identify the importance of cognitive determinants in the development of tourism. The study used general and special methods: systems analysis, synthesis, grouping, systematization, cognitive modeling, cognitive map, pulse method, predictive extrapolation. Target factors, indicators, and control factors influencing the development of tourism in Ukraine are determined and a cognitive model is built, which graphically reflects the nature of the influence of these factors. Four main scenarios of the Ukrainian tourism industry are established on the basis of creating a matrix of adjacency of an oriented graph and forecast modeling based on a scenario approach. The practical significance of the obtained results lies in the possibility of their use to forecast the prospects of tourism development in Ukraine, the definition of state policy to support the industry that will promote international and domestic tourism.

  • Purpose: This study aimed to investigate factors affecting frailty by age groups among vulnerable elders in Korea. Methods: In this secondary analysis, data were collected from records for 22,868 elders registered in the Visiting Health Management program of Public Health Centers in 2012. Health behaviors, clinically diagnosed disease, frailty, depression and cognitive condition were assessed. Data were analyzed using stepwise regression to determine the associated factors of frailty by age group. Results: Alcohol consumption, physical activity, number of diseases, DM, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors significantly associated with frailty among the elders aged 65~74 (F=135.66, p <.001). Alcohol consumption, physical activity, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors associated with frailty in the elders aged 75~84 (F=245.40, p <.001). Physical activity, CVA, arthritis, depression and cognitive condition were factors associated with frailty in the elders over 85 years of age (F=96.48, p <.001). Conclusion: The findings show that frailty of elders and associated factors were different by age group, and common factors affecting frailty were physical activity, CVA, arthritis, depression and cognitive condition. Thus, these factors should be considered in the development of intervention program for care and prevention of frailty and program should be modified according to age group.

  • Objective : To examine the association between dietary factors and cognitive impairment in older Korean women living in the community. Methods : Wave 2 data, from the Suwon Longitudinal Aging Study (SLAS), of 365 women aged 65 years or over, were used. The Korean version of the 30-point Mini-Mental State Examination (MMSE-K) was used to assess cognitive impairment (score$\geq$19). Dietary habits and frequencies of food group consumption were also examined. Results : A total of 67 women (18.4%) were found to be cognitively impaired. In bivariate analyses, nondietary factors, such as age, marital status, education, income, self-rated health, depression, emotional support, social activity, exercise, and dietary factors, such as self-rated nutritional status, frequency of beans and bean products and milk and dairy products consumption were associated with cognitive impairment. In the multivariate analysis, a higher frequency ($\geq$1 vs. <1 time/day) of beans and bean products (OR=0.48, 95% CI: 0.23-0.99) and milk and dairy products (OR=0.25, 95% CI: 0.10-0.61) consumption was inversely associated with cognitive impairment, after adjustment for non-dietary factors. Conclusion : These results suggest that dietary factors may play a significant role in cognitive impairment of older Korean women.

  • Purpose: This study was done to identify differences in factors influencing cognitive function according to the cognition of community dwelling elders. Methods: A convenience sample of 565 community dwelling elders participated in this study and from May to June, 2010 trained research assistants collected data using structured questionnaires. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, correlation, and multiple regression with the SPSS Win 15.0 version. Results: The elders had a slightly low degree of cognitive function. Of the 565 elders, 41.1% were in the normal group for cognitive function and 58.9% in the mild impairment group. Although there were no significant differences in general characteristics between the groups, factors influencing cognitive function were different. Factors influencing elders in the normal group were leisure activity and moderately good health status. These variables accounted for 5.7% of the variance in cognitive function. Factors influencing elders in the mild impairment group were leisure activity, depression, and education level limited to elementary school graduation. These variables accounted for 19.9% of the variance cognitive function. Conclusion: This study provides comprehensive understanding of factors influencing cognitive function in elders. Differentiated nursing interventions according to degree of cognitive function are suggested.

  • Objectives: To identify the factors affecting the cognitive function according to the education level of people aged 65 or older. Methods: This study used the data from the 2014 survey of living conditions and welfare needs of Korean older adults. A total of 10,248 people were analyzed in the final analysis, not including those who responded by proxy and those who did not participate in cognitive function tests. Cognitive function was measured by Mini Mental State Examination -Dementia Screening(MMSE-DS), and logistic regression was performed using the SPSS/WIN 24.0 program. Results: There were differences in factors affecting cognitive function depending on the education level. Overall, regular exercise had a positive effect on maintaining cognitive function, and the higher the education level, the more important it was to maintain the Instrumental Activities of Daily Living(IADL). In addition, for lower education levels, improving the life satisfaction was important to prevent the decline of cognitive function. Conclusions: Based on the results of this research, it is suggested that customized approaches shoud be taken according to education level when developing and implementing programs to prevent the decline of cognitive function.
