The purpose of this study is to investigate how the combined intervention of occupation-based intervention and computerized cognitive rehabilitation treatment affects the psychosocial function, cognitive function, and depression of stroke patients. 23 stroke patients were divided into experimental group(n=11) and a control group(n=12), and the experimental group and the control group received CoTras for 4 weeks and 30 minutes each, and additionally the experimental group received task-based intervention for 30 minutes before the start of CoTras. It was conducted 20 times for a total of 4 weeks. Self-efficacy scale, stress scale, depression scale, neurobehavioral cognitive status examination were used. As a result of the study, the experimental group showed significant improvement in improvement of self-efficacy, stress, and depression than the control group, and the experimental group showed a small effect difference in magnitude of effect from the control group in cognitive function. Based on this study, it is possible to utilize the simultaneous task-based intervention with CoTras to improve psychosocial function, depression and cognitive function in stroke patients.

The purpose of this study was to confirm that the property generalization to social categories with low coherence is stronger when stress due to COVID-19 is perceived as high, compared to when stress is perceived as low. To this end, this study selected categories with high coherence(nun, soldier, flight attendant) and categories with low coherence(wedding planner, interpreter, florist), and recruited 336 participants to perform a category-based inductive generalization task(inferring how many properties repeatedly observed by some category members would appear across all category members), and measured their perceived COVID-19 stress. As a result, this study showed that when the cohesion of social categories is high, the effect of property generalization is stronger than when it is low, and the effect of property generalization is stronger in those who perceive stress due to Corona 19 higher than those who perceive it as low. In addition, this study confirmed that people who perceive COVID-19 stress strongly tend to generalize strongly to properties that are repeatedly observed in the low coherence category. This study is important in that it shows that there is a cognitive mechanism that is at the root of the phenomenon that stereotypes and prejudices deepen and discriminatory behaviors increase after the outbreak of COVID-19, such as COVID-19 stress and the resulting increase in attribute generalization tendency.

Recent research has shown that university students experience severe stress and depleted directed attention due to study, social relationships, and economic dependency. Based on the stress reduction theory and the attention restoration theory, this study aims to investigate the effects of natural landscape on university students' stress and cognitive performance through a wide array of measurements including GSR(galvanic skin responsse), IBI(interbeat interval), ZIPERS(Zucherman Inventory of Personal Reactions), and mental arithmetic test. The restorative effects of natural landscape were compared with those of urban landscape. 128 university students participated in the study, and the data of 120 students was analyzed. The results showed that natural landscape was more restorative in relieving psychological stress and in enhancing cognitive performance than urban landscape, which evidenced the restorative effects of natural landscape. Therefore, it could be proposed that natural landscaping of the university campus contributes to students' stress reduction and cognitive enhancement. But such effects were not found in the two physiological measures(both GSR and IBI). Moreover, it was analyzed that urban landscape had a more beneficial effect than natural landscape for IBI, which might resulted from the participants' characteristics and the study landscape. Specifically, the young age span of the participants(average 23.8 years old) and the very natural setting of the university where they were enrolled might lead to the conflicting results in physiological measures. Also, the urban landscape used in the study had a sense of "scope", which is one of the Kaplan and Kaplan's restorative characteristics. Based on this opinion, it was suggested that future study should investigate the impact of the landscape type and contents as well as the participants' characteristics on the restorative effects of natural landscape.

The present study tested a hypothesis that mood awareness and emotional expressivity would attenuate the association between academic stress and adjustment. In support of the hypothesis, the present research showed that emotional expressivity moderated the association between academic stress and adjustment among college students. That is, the association was attenuated by emotional expressivity when academic stress was high more than when academic stress was low. Curiously, we also identified an interesting diversion between two factors of mood awareness. Specifically, mood monitoring moderated the negative association between academic stress and adjustment, whereas mood labeling did not. That is, mood monitoring was particularly effective when academic stress was high, but mood labeling showed substantial benefits regardless of the level of academic stress. Overall, the present results suggest that mood awareness (in particular, mood labeling) and emotional expressivity serve as cognitive and behavioral protective factors that can buffer academic stress among college students.

The purpose of this study was to analyze that mother's daily hassles, children's cognitive regulation and children's emotive regulation are prospectively related on children's school readiness and to investigated the mediating role of children's cognitive regulation and children's emotive regulation between mother's daily hassles and children's school readiness. Also in particular children's sex. This study used data from 273 preschooler and their mothers from kindergartens and child care centers located in Seoul and Gyeonggi-do. The data was processed by SPSS 24.0 and Mplus 6.0. Pearson's correlation, confirmatory factor analysis(CFA), structural equation modeling(SEM), multi group analysis were used to find out the relationships and mediating effect. The results of this study were as follows: First, mother's hassles had a direct effect on children's cognitive regulation and children's emotive regulation. However, mother's hassles didn't have a direct effect on physical health and motor development, cognition development and general knowledge, social-emotional development, and life habit and attitude. Second, children's cognitive regulation had a direct effect on physical health and motor development, cognition development and general knowledge. And children's emotive regulation had a direct effect on social-emotional development. Third, children's cognitive regulation fully mediated the relation between mother's hassles and physical health and motor development, cognition development and general knowledge of school readiness. Also, children's emotive regulation fully mediated the relation between mother's hassles and social-emotional development of school readiness. Forth, mother's hassles had a little effect on boy's cognitive regulation, but boy's cognitive regulation had effect on physical health and motor development of school readiness stronger than girls.

Accumulation of amyloid beta (Aβ) and oxidative stress are the most common reason of Alzheimer's disease (AD). In the present study, we investigated the cognitive improvement effects of butanol (BuOH) fraction from Momordica charantia in Aβ_25-35-induced AD mouse model. To develop an AD mouse model, mice were received injection of Aβ_25-35, and then orally administered BuOH fraction from M. charantia at doses of 100 and 200 mg/kg/day during 14 days. In the T-maze and novel object recognition test, administration of BuOH fraction from M. charantia L. at doses of 100 and 200 mg/kg/day improved spatial ability and novel object recognition by increased explorations of novel route and new object. In addition, BuOH fraction of M. charantia-administered groups improved learning and memory abilities by decreased time to reach hidden platform in Morris water maze test. Oral administration of BuOH fraction from M. charantia significantly inhibited lipid peroxidation and nitric oxide levels in the brain, liver, and kidney compared with Aβ_25-35-induced control group. These results indicated that BuOH fraction of M. charantia improved Aβ_25-35-induced cognitive impairment by attenuating oxidative stress. Therefore, M. charantia could be useful for protection from Aβ_25-35-induced cognitive impairment.

인지능력 손상으로 인해 치매환자의 정상 언어 사용은 점차 감소되고 좌절감과 스트레스는 상승된다. 신체접촉은 비언어적 의사소통의 한 형태로서 치매환자를 지지하고 스트레스 상황에서 겪는 불안을 완화한다. Hollinger와 Buschmann은 1993년 신체 접촉 모형을 개발하였으며, 그 모형을 적용하여 신체접촉 인지도와 우울과의 관계와 신체 접촉의 우울증감소 효과를 정상 노인과 우울증 노인을 대상으로 연구했다. 그러나, 모형을 치매환자 연구에 적용시켜 검토한 연구는 언다. 본 연구의 목적은 신체 접촉 모형을 비평 분석하는 것이다. 또한, 분석을 기초로 하여 모형을 치매 환자 연구에 적용하도록 변형시켰다. 치매 환자의 인지, 언어 능력은 손상되었지만, 환경에 반응하는 감정과 접촉 감각은 유지되고 있다는 것은 신체 접촉 모형을 치매환자에게 적용할 때 반드시 고려해야 할 점이다. 개인의 문화 차이는 신체 접촉에 대한 인지와 반응에 영향을 준다. 따라서, 연구대상자 선택시 대상자가 신체 접촉을 긍정적으로 받아들이고 있는지를 확인해야 할 것이다. 대상자는 인지 능력 손상으로 면담이나 질문지에 적당히 반응할 수 없으므로 연구시 관찰 방법의 이용을 제언한다.

Purpose: The purpose of this study was to investigate how college students' perceived stress, cognitive stress, and somatization affect their heart rate variability (HRV). Methods: This study is a cross-sectional survey research on 191 university students, registered at the G University. The perceived stress scale (PSS) and cognitive stress response scale, were used to assess level of stress. The somatization symptom scale of the Symptom Check List 90 (SCL-90), was used to assess level of somatization caused by stress. To assess heart rate variability (HRV), we conducted a five-minute test using a pulse wave analyzer, to analyze short-term HRV. Results: The SCL-90 somatization score had relatively high positive correlation (p< .001) with cognitive stress, but low positive correlation (p< .001) with perceived stress. Cognitive stress response had low negative correlation (p< .001) with 1nSDNN and 1nRMSSD among HRV parameters. Perceived stress was not correlated with HRV. Multiple regression analysis showed that variables of perceived stress, cognitive stress, and somatization symptoms, could not explain HRV. By contrast, one of the HRV indicators, 1nSDNN, was affected by age, gender, and aggressive-hostile thought, the latter being a subscale of the cognitive stress response scale. Conclusion: This study suggests that stress evaluation for people in early adulthood will be more effective, if the evaluation examines cognitive stress and heart rate variability.
