  • Purpose : This study aimed to identify the prevalence and risk factors of cognitive impairment in survivors discharged from the intensive care unit (ICU). Methods : This secondary analysis study utilized data from a multicenter prospective cohort of post-ICU patients. We analyzed the data of 175 patients enrolled in the primary cohort who completed the cognitive function evaluation three months after ICU discharge. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) scale. The cut-off points for cognitive impairment were < 23 for face-to-face evaluation and < 18 for telephone evaluation. Results : The prevalence of cognitive impairment three months after ICU discharge was 32.6%. Significant risk factors for cognitive impairment were age ≥ 60 years (OR=10.52, 95% CI=3.65~30.33, p<.001), education < high school graduation (OR=2.53, 95% CI=1.07~6.01, p=.035), unplanned ICU admission (OR=4.01, 95% CI=1.45-11.14, p=.008), and delirium in the ICU (OR=4.33, 95% CI=1.08-17.23, p=.038). Conclusion : ICU nurses should use preemptive strategies to reduce post-ICU cognitive impairment of patients with risk factors. It is necessary to frequently assess and detect early delirium in critically ill patients, while attempting various non-pharmacological interventions.

  • This paper aims to propose a cognitive evaluation model to be utilized in designing game devices and developing relevant software with the purpose of the prevention of dementia of the elderly among various types of serious games for the elderly intending to improve their physical, mental or social capability. Firstly, a serious game for the elderly has been developed based on the guidelines of the areas pertaining to existing hardware, software and contents. Secondly, a pre-experiment of the game targeting specialists has been conducted in order to re-establish a cognitive evaluation model for the developed result. Thirdly, the cognitive evaluation model for the serious game for the elderly that intends to improve their cognitive capacity has been materialized based on the experiment results. Given the fact that the scope of game contents, most of which used to be focused on teenagers, have been gradually expanding to cover wider range of social classes than ever before, it is expected that the results of this study could be utilized as a model that can verify the games and their contents with special purposes based on the cognitive evaluation of the users.

  • Objective: The purpose of this study is to select a cognitive training game that can evaluate five cognitive domains and to study their validity with existing cognitive evaluation tools. Design: Methods: Delphi survey was conducted through the 2nd questionnaire for 30 experts to select games suitable for training 5 cognitive domains. Five cognitive training games and Mini Mental State Examination - Korea(MMSE-K), and cognitive impairment screening test(CIST) were conducted for 82 elderly in the community. Pearson correlation analysis was performed to find out the correlation of the three tests. The ROC curve was used to calculate the selection criteria for the game results for the screening evaluation of the presence or absence of mild cognitive impairment. Results: The coefficient of variation to evaluate the stability of the Delphi survey was less than 0.50 in most game items. The 'correct answers' and 'level' of the five final selected game items showed a statistically significant positive correlation with the CIST and MMSE-K scores. CIST score and 'time' of all game items except 'number making_time' showed a statistically significant negative correlation. Conclusions: The validity of the cognitive training program using smart devices was evaluated, and the criteria for classifying the cognitive domain and distinguishing the presence or absence of cognitive impairment were confirmed.

  • High cognitive workload decreases a driver's ability of judgement and response in traffic situation and could result in a traffic accident. Electrocardiography (ECG) has been used for evaluation of drivers' cognitive workload; however, individual differences in ECG response corresponding to cognitive workload have not been fully considered. The present study developed an evaluation method of individual driver's cognitive workload based on ECG data, and evaluated its usefulness through an experiment in a driving simulator. The evaluation method developed by the present study determined the optimal ECG evaluation condition for individual participant by analysis of area under the receiver operating characteristic curve (AUC) for various conditions (total number of conditions = 144) in terms of four aspects (ECG measure, window span, update rate, and workload level). AUC analysis on the various conditions showed that the optimal ECG evaluation condition for each participant was significantly different. In addition, the optimal ECG evaluation condition could accurately detect changes in cognitive workload for 47% of the total participants (n = 15). The evaluation method proposed in the present study can be utilized in the evaluation of individual driver's cognitive workload for an intelligent vehicle.

  • Purpose: The purpose of this study was to examine cognitive functions, depression, and life satisfaction among the elderly receiving visiting nursing services. Methods: The subjects of this study consisted of 221 elderly individuals who were receiving visiting nursing services from a public health center located in Gyeonggi-do. The Mini-mental State Examination Korea version (MMSE-K), Geriatric Depression Scale-short form-Korea version (GDS-K), and Life Satisfaction Scale were utilized to determine cognitive functions, depression, and life satisfaction, Collected data was analyzed by the SPSS PC Win 12,0 program. Results: The prevalence of cognitive impairment (MMSE-K$\leq$24) was 86.4%, and the proportion of severe depression (GDS-K$\leq$10) was 22,6%, Older age, lower education, and low income were associated with cognitive impairment, and low education, no religion, and low income were associated with depression. Cognitive function negatively correlated with depression. Life satisfaction level was fairly low and was not associated with any variables. Conclusion: The high prevalence of cognitive impairment and low life satisfaction status were determined among low-income elderly who were registered at a visiting health care center. Thus, in the future at visiting health care services, efficient and various programs for the elderly should be tried, to improve cognitive functions and reduce depression. Additionally, consistent evaluation studies for those programs will be required.

  • The purpose of this research is to develop a protocol which can quantitatively evaluate cognitive ability that is needed when elderly people use mobile phone. Since previous methods for measuring the cognitive ability of elderly people was mainly for clinical evaluation, they would not be adequate to measure cognitive ability for mobile phone development. Therefore, this study suggests cognitive areas which are necessary to use the mobile phone based on the existing evaluation tools. The cognitive areas consist of language, visuospatial ability, memory, executive function and perception. New questionnaire was developed to evaluate the individual cognitive ability for the elderly. They include 9 questions for button comprehension test, 8 for icon button comprehension test, 10 for vocabulary comprehension test, 8 for menu comprehension test, 3 for icon size test, and 2 for font size test. The protocol can be used in the field although further modification may be necessary for betterment.

  • Cognitive-behavioral approach to two cases with chronic headache was presented. Cognitive-behavioral interventions focus on indirectly altering symptom-related physiological activity by changing the way patients cope with headache-eliciting stressors. This treatment focuses directly on the patients' cognitive and behavioral changes. Cognitive-behavioral treatment can be divided into three phases Education, self-monitoring, and problem-solving or coping-skills training. Literature reviews on the follow-up evaluation of therapeutic effectiveness revealed that cognitive-behavioral treatment is effective in the management of chronic headache.
