Changes in visuospatial cognitive performance, blood oxygen saturation and heart rate due to the highly concentrated oxygen administration were observed in this study. Six male ($25.8 \pm$1.0) and six female (($23.8 \pm$ 1.9) adults were asked to perform 20 visuospatial tasks with the same level of difficulties by supplying two different oxygen levels (21%, 30%). Experiment consisted of Rest1 (1 min.), Control (1 min.), Task (4 min.), and Rest2 (4 min.) and physiological signals such as blood oxygen saturation and heart rate were measured through each stage. The result showed the accuracy of task performance increased significantly at 30% oxygen concentration compared with 21%, which means oxygen supply has positive effects on visuospatial cognitive performance. When 30% oxygen was supplied, blood oxygen saturation during control and task phases was increased and heart rate was decreased compared with 21%. It means that 30% oxygen can stimulate brain activities by directly increasing the actual level of blood oxygen concentration during cognitive performance, and enough oxygen supply during cognitive performance make heart rate decrease.

Purpose : This study aimed to understand the influence of the virtual reality program combined with cognitive activity on elderly people's balance ability. Method : We randomly divided 14 elderly people receiving daytime protection service from D daytime protection center for senior citizens located in Busan-si into a group(seven) with cognitive activity combined with virtual reality program, and the other group(seven) with only virtual reality program. In order to compare the balance ability before/after the therapeutic intervention, the Berg Balance Scale was carried out. The Mini-Mental State Examination-Korea(MMSE-K) was also conducted to compare their cognitive functions. Result : Both groups showed statistically significant differences in balance ability before/after the therapeutic intervention(p<.05) while there were no statistically significant differences in balance ability after the therapeutic intervention(p>.05). The cognitive functions before/after the therapeutic intervention were not statistically significantly different in both groups(p>.05). Conclusion : The findings showed that the application of virtual reality program combined with cognitive activity could improve elderly people's balance ability. It is considered that the application of virtual reality program can have positive influence on the improvement of elderly people's balance ability, as an intervention method for improving balance ability in the future.

A physician's empathy plays a crucial role in patient-centered care, and in modern medicine, patients, their caregivers, and society demand a high level of empathy from healthcare providers. The conceptualization of clinical empathy, which has emphasized cognitive empathy since the mid-20th century, has been widely accepted in medical schools and the healthcare industry without much critical ref lection. This study provides an overview of the ongoing debates on empathy versus sympathy and cognitive empathy versus affective empathy to clarify the concept of empathy. Based on recent research findings, clinical empathy is proposed to encompass three components: cognitive empathy, affective empathy, and empathic motivation. It is suggested that fully demonstrating these components requires empathic communication skills. Additionally, the cognitive characteristics of medical students and the features of the academic environment demonstrate the need for education to strengthen their empathy skills. Considering this, proposed intervention methods that medical schools can consider include utilizing tutoring programs and debriefing processes for team activities, which can facilitate problem-solving as a coping strategy for stress. Learning communities can create an environment where students can receive social support and recover from stress. Medical schools can contribute to the development of students' professional identities as practicing clinicians who embody empathy and respect by cultivating professors as positive role models. Additionally, utilizing scales to assess the empathic nature of doctor-patient communication or incorporating patients and caregivers as evaluators can actively improve empathic communication skills.

The purpose of this study was to investigate the role of calculators as a cognitive tool rather than calculating tool in learning elementary school mathematics. The calculator activities on multiplying two numbers ending with 0s or two decimal fractions and mixed four operations were developed, and exploratory lessons with the activities were implemented to three 3rd graders and two 5th graders. The results were shown that calculators provided an alternative effective learning environment: students were able to use heuristic thinking, reason inductively and successfully investigate principles of mathematics through the pattern recognition. And finally, we discussed the heuristic method through utilizing calculators.

The major limitation of the traditional Intelligent Tutoring Systems (ITS) is that interface is mainly focused on the cognitive factors. However, the new direction of ITS is shifting form the cognitive perspectives to the motivational perspectives reflecting the individual differences. In this study, the specific design guidelines for motivational interface of ITS are proposed to promote learner's motivation to learn during the interaction with the ITS. First, ITS should be able to reflect individual differences in cognitive abilities, interest and motivation, and ongoing changes of the interestingness and comprehensibility during learning activities. Second, it is essential for ITS to guarantee learner controllability, diverse learning activities, curiosity, self-relevance, and challenge to enhance the level of motivation and situational interest. Third, the game-like properties are also needed to maximize the motivational effect of learning with ITS.

Objective: The self-decisions of the client regarding the meaningful work as a therapeutic approach of client-orientation. The Cognitive Orientation to daily Occupational Performance (CO-OP) is an occupation-oriented problem-solving approach. The purpose of this study was to describe the goals and intervention protocols of CO-OP in those affected by stroke. Design: A systematic review. Methods: Using EBSCOhost, PubMed, and ProQuest databases, we searched studies published in the past decade that utilized the CO-OP intervention. An initial search revealed 71,171 potential articles. After applying our search criteria to screen the titles, abstracts, and full-text, we included 7 articles that met our inclusion and exclusion criteria. In this study, we used the patient, intervention(s), comparison, outcome method to analyze the 7 selected studies. We analyzed the frequency of goals and intervention protocols. Results: Seven articles met our selection criteria; these studies included participants with an almost normal cognitive function from inpatient and outpatient rehabilitation facilities. CO-OP was used for 237 goals; the most used goal was the instrumental activities of daily living. The training procedure used 3 types of self-selecting goals in the activities. One of the goals was not trained, but was only evaluated to determine the generation effect. The most common outcome measurements included the Canadian Occupational Performance Measure and the Performance Quality Rating Scale. Conclusions: This research provided information about the effectiveness of CO-OP and selecting the correct evaluation tool to assess the efficiency of the intervention. This study suggests that treatment with CO-OP in occupational therapy is effective and that it outlines common protocols.

The aim of this study was to investigate the effects of the water extract of Albizziae Cortex (AC) on the learning and memory impairments. AC was administered to normal mouse and scopolamine-injected amnesia mouse model. Passive avoidance test, Y-maze test, and Morris water maze test were conducted to confirm the cognitive-enhancing activities of AC. Acetylcholinesterase (AChE) activity and acetylcholine (Ach) content were measured after oral administration of AC. On the passive avoidance test, AC (200 mg/kg) significantly increased latency time and recovered scopolamine-impaired learning and memory in mice. In addition, AC (200 mg/kg) reduced Exploration time in target quadrant and reversed the scopolamine-induced cognitive impairments in the Y-maze test. Moreover, AC (200 mg/kg) increased exploration time in target quadrant and improved scopolamine-reduced escape latencies in the Morris water maze test. These effects were presented by regulatory effects of AC on AChE activity and Ach content. Taken together, AC increases cognitive-enhancing activities and ameliorates scopolamine-induced learning and memory impairment. AC might be a potential agent for prevention and treatment of amnesia and dementia.
