  • Objectives: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. Methods: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). Results: The control group ($GDS{\leq}9$) when compared with mild ($10{\leq}GDS{\leq}16$) and severe ($17{\leq}GDS$) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted $R^2$=35.6%, p<0.001) and BVRT-A score (adjusted $R^2$=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted $R^2$=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. Conclusion: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

  • The purpose of this study was to investigate the effects of Thinking Science program on the cognitive acceleration and cognitive processing skills of the elementary school students. Subjects included 305 5th grade students in three elementary schools. Subjects were divided into the experimental and the control groups. Thinking Science program was implemented to the experimental group over a period of two years. Statistically significant gains on the cognitive acceleration were shown by the experimental group compared with the control group. The intervention effects on the cognitive acceleration were shown for the girls of the elementary schools. It was also found that Thinking Science program exerted significant effect on the development of the cognitive processing skills of the students. The experimental group gained higher scores of attention and simultaneous processing skills compared with the control group. This implied that Thinking Science program was effective not only on the cognitive acceleration but also on the development of the cognitive processing skills as a far-transfer.

  • 최근 뇌에 대한 연구가 활발히 진행되고 있으며 뇌 기능의 중요성이 부각됨에 따라서 뇌 기능과 관련한 인지능력에 대한 관심이 높아지고 있다. 인지능력은 정보의 입력, 처리, 저장 및 검색 등 광범위한 지적 능력을 가리키고 기억력, 주의력, 집중력 등이 포함된다. 하지만 이러한 인지능력의 중요성에도 불구하고 인지능력을 증진시키고 회복시키기 위해 많은 시간을 할애할 수 없다. 이는 현대의 사회적 환경과 시간적, 공간적인 제약이 많기 때문이다. 본 논문에서는 휴대성과 시간의 효율성을 고려하고 사용자에게 다양한 기능을 제공할 수 있는 스마트폰을 활용하여 인지능력 진단 및 증진을 할 수 있도록 시스템을 설계 및 구현하였다.

  • 기술적 혁신과는 달리 상징적 혁신(symbolic innovation)은 기존 제품에 부가된 사회적 의미가 변화함으로서 창조된다. 따라서, 상징적 혁신에서 새로운 사회적 의미와 관련된 속성은 기능적 속성만큼이나 중요하다. 본 연구는 상징적 혁신의 대표적인 의류제품을 이용, 패션혁신행동에 영향을 미치는 인지된 혁신속성(perceived innovation attributes)을 구별하고, 패션혁신행동의 두 유형(구매와 사용)에 미치는 이러한 속성의 영향을 고찰하였다. 대학생 집단을 표본으로 이용, 설문지 조사를 통해 수집된 515부의 응답지가 분석되었다. 인지된 혁신 속성은 유사성(compatibility), 기능적 상대적 잇점, 사회적 상대적 잇점, 인지된 위험으로 구분되었다. 의복흥미가 구매와 사용 두 측면의 패션혁신행동에 영향을 주었으나 인지된 혁신속성은 사용측면에만 영향을 주었다. 유사성과 기능적 상대적 잇점이 사용혁신행동에 긍정적 영향을, 인지된 위험이 부정적 영향을 미쳤다. 혁신속성이 영향을 미치지 않은 반면 의류소비정도가 구매혁신에 영향을 주었다. 본 연구의 결과는 사용혁신성이 높은 소비자는 구매혁신성이 높은 소비자보다 혁신속성의 평가에 더 관여한다는 것을 시사한다.

  • This study developed a occupational therapy convergent activity program to provide dementia patients admitted to the daytime ward, and investigated the program's effect on the hand and cognitive functions and instrumental activities of daily living. A total of 34 dementia patients were divided into two groups: a convergent occupational therapy program and medication were provided for 17 patients, and medication alone was provided for a control group of 17. The intervention was performed for 24 weeks, 8 times per week, 192 times in total. A handgrip strength test was performed to examine hand function before and after the intervention, and the MMSE-K and GDS were performed to evaluate cognitive function. In addition, the K-IADL was used to assess instrumental activities of daily living. With intervention, the experimental group showed significant improvements in hand and cognitive function and instrumental activities of daily living. In contrast, the control group did not show improvements in hand and cognitive function or instrumental activities of daily living. In conclusion, the study showed that a convergent/integrated activity program for occupational therapy has a positive effect on hand and cognitive function as well as instrumental activities of daily living.

  • As the elderly population increases, the prevalence of various geriatric chronic diseases and dementia diseases is also rapidly increasing; accordingly, dementia is becoming a major concern of our society. In this study, 48 elderly patients with mild cognitive impairment located in K district were selected from a group of experimental groups in one building and a control group in one building and evaluated for blood homocysteine levels and cognitive function changes after 4,8, and 12 weeks of taking vitamin supplements. The Chi-squared test, Fisher's Exact test, independent t-test, repeated measures ANOVA, contrast test, repeated measures ANCOVA, and Wilks' lambda test were utilized to analyze the data. The results revealed that the cognitive function of the experimental group was significantly higher than that of the control group at 12 weeks (p<0.05), and so, the experimental group higher than that of the control group (p<0.01), the effect of taking vitamins was significantly increased, indicating that homocysteine was decreased relative to the control group. Therefore, vitamin supplements may prevent decreases in cognitive functions and dementia among elderly patients with mild cognitive impairment.
