Purpose: The purpose of this study was to evaluate effects of a cognitive improvement program on cognition, activities of daily living (ADL), depression, life satisfaction, and grasping power in small groups. Methods: A nonequivalent control group pretest-posttest design was used. Participants were 127 elders who were never diagnosed with dementia and could read (experimental: 61, control: 66). The program was consisted of 8 sessions to improve vocabulary and writing skills and fine motor skills. Each session was applied once a week for 8 weeks. A group was consisted of less than five members. Results: Cognition (t=3.82, p<.001), depression (t=-2.24, p=.027), life satisfaction (t=2.25, p=.027), and grasping power (Rt: t=2.44, p=.016, Lt: t=2.63, p=.010) except ADL (t=-0.49, p=.622) were significantly increased in the experimental group after the cognitive improvement program compared to the control group. Conclusion: This study indicates that the cognitive improvement program was effective to improve cognition, depression, life satisfaction and grasping power. Further study is needed in order to identify continuous effects of this cognitive improvement program.

The purpose of this study was to develop MBL(Microcomputer Based Laboratory) programs for sixth-grade elementary students in science laboratory instructions and to ascertain the effects of this program on academic achievement and science-related affective characteristics. In laboratory instructions, using the MBL was found to be effective in improving academic achievement for elementary students, especially in the domain of knowledge. In addition, it helped students to improve science-related affective characteristics. The experimental group showed higher levels, especially in the domains of cognition and interest. When our findings were analyzed in detail, the sub-domains that showed positive effects included 'cognition of science' in the domain of cognition, and interest toward science', 'interest toward science learning', 'interest toward science related activities', and 'anxiety for science' in the domain of interest. Male students exhibited improvement in the domain of cognition while female students showed improvement in the domain of interest. In conclusion, utilizing MBL programs as an experimental measurement in the real field of elementary science education can be said to be both positive and desirable.

Background : The purpose of this study was to investigate the understanding and the attitude of Korean hospital CEOs toward the healthcare quality improvement. Methods : A mailed questionnaire survey to the CEOs of hospitals with 400 beds or more was conducted between September 15 and October 30, 2000. Of the 108 hospitals eligible for the study, 58 participated, yielding a response rate of 54 percent. Result : The hospital CEOs have expressed that their hospital management was arduous job, and they had been pressured by increasing competitions among healthcare providers. They indicated that the low fees of health insurance made their hospital management difficult. The results also indicated that there was general consensus that the improvement of service quality was important in encouraging their organizations, but the investment of manpower and equipment ranked higher than the improvement of service quality. The majority of the CEOs have good understanding about quality improvement activities. However the facts that in general QI must be focused at the process of services and customer satisfaction, meanwhile quality improvement activities are helpful for the organizational productivity embarrassed them. The hospital CEOs responded that there were successful changes in terms of quality of care, patient satisfaction, and process efficiency after QI activities, but no increase in patient number and profit. Lack of understanding to QI activities and limited budget seem to attribute unsatisfactory outcomes. Conclusion : The majority of Korean hospital CEOs have a good understanding and attitude about QI activities. As mentioned in the result, despite of several limitations, several facts regarding the CEOs of hospital in Korean can be elucidated. (1) The general cognition of the QI project is relatively high, and it is accepted with positive concern, (2) the priority of the QI project, however, is not set higher than other projects and (3) the specific concepts of the actual QI project such as customer (patient)-focused work driving, the recognition of the work accomplishment, and the importance of rewards have not sufficiently understood.

The purpose of this study was to investigate effect of methanolic extracts of 10 kinds of wild vegetables cultivated in Gangwon province on antioxidant activity, acetylcholinesterase, and β-secretase inhibitory activities. Results showed that among the wild vegetables, Aralia elata(Miq.) Seem shoot extract exhibited the highest total phenol content (84.65±1.08 mg GAE/g) and total flavonoids content (70.77±0.55 mg RE/g), respectively. The antioxidant activity of wild vegetables extracts was measured by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay. Aralia elata(Miq.) Seem shoot extracts had the highest DPPH and ABTS scavenging activity (90.16%, 40.18% at 2 mg/mL). As a result, Aralia elata(Miq.) Seem shoot extract was the most effective in terms of acetylcholinesterase inhibitory activity (35.94% at 1 mg/mL). In the β-secretase activity assay, all 10 kinds wild vegetables extracts showed low inhibitory activity, and Aralia elata(Miq.) Seem shoot extract had highest inhibitory activity among the 10 wild vegetables extracts was 14.99%. Taken together, these results showed that Aralia elata(Miq.) Seem shoot extract has potential cognition improvement impact, suggesting that it may provide an effective strategy for improving cognition.

Purpose : This study investigates the effects of the application of traditional occupational therapy and the korean computerized cognition training system on the cognitive function and performance of daily activities of stroke patients with cognitive impairment. Methods : From inpatients referred for rehabilitation treatment at L Rehabilitation Hospital located in Busan, 20 patients diagnosed with stroke from April 05. 2021 to May 02. 2021 (study period) were selected, They were divided into two, an experimental group consisting of 10 subjects who underwent a computerized cognitive rehabilitation program and traditional occupational therapy in combination and a control group of 10 subjects who underwent traditional occupational therapy alone. In order to measure the cognitive function of the subjects before the intervention, two assessment tests were conducted: a Neurobehavioral Cognitive Status Examination (NCSE), which evaluates stroke-related cognitive ability, and a Functional Independence Measure (FIM) test, which evaluates life activities. Then, both groups received a total of 20 training sessions at 30 minutes per session, five times a week for four weeks. Results : A statistically significant difference was found in cognitive function between before and after the cognitive training for both the experimental group and the control group. For the FIM scores, statistically significant differences were observed after intervention in the categories of handling personal matters and social cognition, and in the total score. The average scores of the remaining items also improved. Conclusion : The results of this study showed that both the computerized cognition rehabilitation program and the traditional occupational therapy had a positive effect on the improvement of cognitive function in stroke patients.

Evidence regarding the efficacy of Ginkgo biloba extract on cognitive function has been contentious. This study evaluated the effective period of G. biloba intake to improve cognition in the elderly. PubMed, EMBASE, Cochrane, Web of Science, and PsycArticles databases were searched for short-listing relevant studies. Twenty-five studies fulfilled the inclusion criteria. Cognitive efficacy was assessed based on the duration of intervention. G. biloba intake for 3-6 months statistically significantly affected cognitive function (SMD= -0.21; 95% CI -0.39, -0.03; p=0.02). However, the improvement in activities of daily living (ADLs) was not statistically significant. Thus, G. biloba intake for more than three months improves cognition in the elderly people with cognitive impairment and AD dementia without any safety risk. Intake for up to six months does not improve ADLs significantly in mild to moderate dementia patients.

The purpose of this study was to demonstrate clinical effects on cognition, visual perception, depression, anxiety, and activities of daily living by applying the N-BACK program, a brain stimulated training program, which is used for the clinical purpose. To prove this, subjects suspected of cognitive impairment with 18-23 points in a Korean version of mental status examination (MMSE-K) were recruited among the population who had been diagnosed with stroke duration and suffered from it for six months of duration, and 10 of the subjects were selected into the experimental group and the control group, respectively. A total of 20 sessions were carried out for 30 minutes per day 5 times for 4 weeks. As a result, the experimental group who has been applied the N-BACK program showed positive results in the improvement of cognition, visual perception, depression, anxiety, and daily living skills. The results obtained from this study expect us that applying the N-BACK program for the improvement of cognition, visual perception, depression, and anxiety to stroke patients has a positive effect on the rehabilitation of patients and will lead them to improve daily living activities more independently.

BACKGROUND/OBJECTIVES: The accumulation of amyloid-${\beta}$ ($A{\beta}$) in the brain is a hallmark of Alzheimer's disease (AD) and plays a key role in cognitive dysfunction. Perilla frutescens var. japonica extract (PFE) and its major compound, rosmarinic acid (RA), have shown antioxidant and anti-inflammatory activities. We investigated whether administration of PFE and RA contributes to cognitive improvement in an $A{\beta}_{25-35}$-injected mouse model. MATERIALS/METHODS: Male ICR mice were intracerebroventricularly injected with aggregated $A{\beta}_{25-35}$ to induce AD. $A{\beta}_{25-35}$-injected mice were fed PFE (50 mg/kg/day) or RA (0.25 mg/kg/day) for 14 days and examined for learning and memory ability through the T-maze, object recognition, and Morris water maze test. RESULTS: Our present study demonstrated that PFE and RA administration significantly enhanced cognition function and object discrimination, which were impaired by $A{\beta}_{25-35}$, in the T-maze and object recognition tests, respectively. In addition, oral administration of PFE and RA decreased the time to reach the platform and increased the number of crossings over the removed platform when compared with the $A{\beta}_{25-35}$-induced control group in the Morris water maze test. Furthermore, PFE and RA significantly decreased the levels of nitric oxide (NO) and malondialdehyde (MDA) in the brain, kidney, and liver. In particular, PFE markedly attenuated oxidative stress by inhibiting production of NO and MDA in the $A{\beta}_{25-35}$-injected mouse brain. CONCLUSIONS: These results suggest that PFE and its active compound RA have beneficial effects on cognitive improvement and may help prevent AD induced by $A{\beta}$.
