이 연구의 목적은 자기주도 초등교재의 조망인지기제 활용이 학업성취도 향상에 미치는 효과에 대해 살펴보고 학업성취도 향상에 영향을 주는 조망인지 하위 구성요소(계획, 점검, 평가)가 무엇인지 알아보고자 하는 데 있다. 연구목적을 달성하기 위해 실험집단(조망인지기제 활용 학습교재사용 집단)과 통제집단(기존 교재사용 집단)으로 구성된 초등학생 55명을 대상으로 실험을 실시하였다. 분석결과 첫째, 자기주도 초등교재의 조망인지기제 활용집단(M=70.38)과 전통식 학습집단 (M=60.84)의 학업성취도 평균은 통계적으로 유의미한 차이를 보였다. 둘째, 조망인지 하위 구성요소 중 '점검' 요소가 학업성취도 향상에 긍정적인 영향을 미치는 것으로 밝혀졌다.

감미료는 감각을 만족시키는 기능을 가지며, 에너지를 공급하는 영양적 감미료와 에너지를 공급하지 않는 비 영양적 감미료로 분류 될 수 있다. 영양적 감미료들은(설탕, 과당 등) 미국 식약청에서는 일반적으로 안전하다고 인식(generally recognized as safe, GRAS) 되고 있다. 그러나 감미료 섭취는 적절한 영양섭취와 건강과 관련하여 아직 많은 우려를 가지고 있다. 첨가당으로부터의 에너지 섭취가 총 에너지 섭취의 25% 이상이면 식사의 질(quality)이 낮아진다. 지난 수 십 년 간, 당 섭취가 행동적인 면에 부정적으로 작용한다는 많은 이론들이 대두되었다. 그러나 포도당은 뇌의 주요 에너지원이다. 포도당의 기억력 향상기능은 모든 연령에서 보고되었으며, 특히 젊은 층보다는 노인에서 더 효과적이었다. 특히 적당량으로 섭취하였을 때 포도당의 섭취는 단어기억, 이야기 기억, 24시간 전에 학습한 정보에 대한 기억, 경계(vigilance)의 향상, 반응시간의 단축, 정신적 계산 능력의 향상, 시뮬레이터 조절에서의 실수감소, 스투르프효과(Stroop effect)의 감소, 지능검사의 향상, 실제사건에 대한 기억력 검사와 웩슬러 척도(Wechsler Scale)에서의 향상과 같은 여러 인지능력 검사에서 좋은 영향을 미친다고 한다. 포도당 용액과 간식의 섭취는 기억력을 개선한다. 아침식사를 거르는 것은 아동들에서 낮은 학습능력을 보인다. 인지능력 변화와 관련 있는 식이는 뇌에 포도당을 공급하는 것과 관련 있다. 과당도 동물실험에서 기억력을 향상시키는 기능이 있다는 것을 보여주고 있다. 본 논문은 당 섭취가 인지능력에 미치는 영향에 대한 과학적인 연구들을 종합하여 정리한 것이다.

Objective : Through the application of the Anderson model, this study provides an empirical analysis of the decision-making factors for participation in cognitive improvement programs for the elderly living in the community. Methods : This study was conducted through an online survey. The participants were elderly people aged 65 years or older living in the community. The survey had 154 participants and was conducted over a two-month period from August to September 2020. Results : The main results of this study were as follow: first, there was no correlation between the predisposing factors and cognitive improvement program; second, among the enabling factors, diversity, interest, and effectiveness of the program were correlated with the cognitive improvement program; and third, there was no correlation between participation in the cognitive improvement program and need factors. Conclusion : This study shows that the results of basic information and evidence will be identified through analysis of the results of the study and that the implications for the development of cognitive improvement programs will be obtained in the future.

Objective : The purpose of this study is to find out the effects of a Home-based cognitive occupational therapy program conducted for the dementia patients in the initial stages living in Taebaek region in Gangwon-do. Methods : This study carried out Home-based cognitive occupational therapy intervention by 30 Occupational Therapy Dept. students and volunteers targeting 30 dementia patients in the initiative stages for eight sessions, once a week. To identify the change of cognitive function of the participants before and after the program, MMSE-K was used for measuring. Results : As a result of applying Home-based cognitive occupational therapy to the dementia patients in the initial stages, overall cognitive function improvement was demonstrated. Especially, statistically significant improvement was exhibited in orientation, memory retrieval, the concentration of attention, and language ability. Conclusion : The program for cognitive function improvement is considered to be usefully applied to intervention in the dementia patients. The development of various Home-based occupational therapy intervention programs is required in order to adopt the Home-based occupational therapy service in the future.

This study suggests how to use tablet PC application to improve the cognitive functions of the elderly. As a part of lifelong education, this study analyzes cases of developing and applying smart application programs to contribute to the enhancement of science education as an elderly education. For the research, we set the direction of the program and developed the programs 'Coloring,' 'Building lights,' 'Matching shapes,' and 'Pressing button' accordingly. As a result of applying the program to nine participants, each program has a positive effect on the improvement of cognitive function of the elderly. This shows the possibility of using smart applications as a cognitive function enhancement program for the elderly.

Objective : The purpose of this study aimed to find out about the impact of RAPAEL Smart Glove on cognitive function and Daily living. Method : While 15 experimental group was given 'RAPAEL Smart Glove', 15 control group was given traditional cognitive rehabilitation. LOTCA, NCSE and MBI were taken to assess cognitive function and activities of daily living of two group before and after each intervention. Result : Cognitive function and Activities of Daily Living of both experimental group and control group presented statistically significant difference before and after each intervention(p<.05). But Statistically, the experiment group presented a significant improvement. Conclusion : The result of this study indicates that the existing rehabilitation treatment and 'RAPAEL Smart Glove' together can produce good effect on cognitive function and activities of Daily Living of mild cognitive impairment patient.

Globally, the elderly population is increasing, making the primary concern of modern society the healthy aging and welfare and medical facilities for the elderly. However, many seniors experience cognitive decline due to aging, making cognitive activities crucial for them. In this context, a study has developed a cognitive activity support system for the elderly using the metaverse. To achieve this, the characteristics and needs of the elderly were analyzed to design an interface in the metaverse that they can easily use. Additionally, the type and difficulty of cognitive activities were adjusted to engage seniors in a captivating manner. Experimental results showed that the proposed system effectively enhances the cognitive abilities of the elderly. Thus, the personalized metaverse-based cognitive activity support system proposed in this study can be a valuable tool for improving the cognitive abilities of the elderly.

Recently, the population of the elderly in Korea has been rapidly increasing, and the medical problems related to the increase of the elderly population and the cognitive decline of the elderly are becoming big social issues. In this study, a task analysis is conducted to develop a cognitive rehabilitation program aimed at improving the IADL(instrumental activities of daily living) of the cognitively deprived elderly. Especially, we focused on analyzing financial management task with ATM use. The task analysis scenario developed through this study is the basis for the development of educational programs to improve the IADL of the cognitively deprived elderly.

In this paper, we propose first a scheme of grouping spectrum holes that are created in the multiple channels of primary users, and then by using the scheme we enhance quality of service (QoS) of wideband cognitive radio users in cellular cognitive radio networks. In our scheme, spectrum holes created in each primary channel are predicted by Wiener prediction process, and then the predicted spectrum holes happened in the same time are grouped into a group. The wideband cognitive radio users explore the group of spectrum holes to improve their QoS. Simulation results show that their handoff calls dropping rate and initial calls blocking rate are significantly reduced in our scheme, compared to those in the single primary channel.

전통적인 수학교육은 간단한 수학적 사실을 이해하고 활용하는 측면에 있어서는 효과적일 수도 있지만, 수학적 개념, 원리, 법칙을 학생 스스로 탐구, 발견하고 창조하는 능력을 기르는 데는 적절하지 않다. 이러한 능력을 기르기 위해서는 학생들 스스로가 관찰, 조작, 분석, 종합하는 활동을 강화할 필요가 있다. 구체적 조작물을 학습도구로 활용하는 경우, 수학 학습에 대한 흥미와 자신감을 길러 주고, 자신의 수준에 맞는 내용을 자기 주도적 학습을 통하여 성취감을 가지게 하며, 학생 스스로 탐구 활동을 활발히 하는데 도움이 된다. 삶의 질이 급격히 향상되는 정보사회에서는 사이버 공간의 등장으로 공간감각 기능의 필요성이 더욱 절실한 바, 현행 수학교과서에서 제공되는 각종 공간 도형들은 3차원 공간에서 이루어지지 않고 평면도형으로 처리함으로써 아동의 도형인지 능력 향상에 큰 효과를 기대하기 어렵다. 이에 본 연구에서는 아동의 인지발달 단계를 고려, 도형인지능력 향상을 위한 선 및 점대칭 관련 동기유발, 선수, 기본, 보충, 심화, 평가, 도움말 관련 프로그램을 개발, 적용한 결과 학습자의 동기가 유발되고, 도형 인지능력 향상에 유의미한 결과를 얻었다.
