The purpose of this study was to examine and analyze the cognitive demand of the mathematical tasks suggested in the middle school textbooks. In particular, it aimed to reveal the overall picture of the level of cognitive demand of the mathematical tasks in the strand of geometry in the textbooks. We adopted the framework for mathematical task analysis suggested by Stein & Smith(1998) and analyzed the mathematical tasks accordingly. The findings from the analysis showed that 95 percent of the mathematical tasks were at high level and the rest at low level in terms of cognitive demand. Most of the mathematical tasks in the textbooks were algorithmic and focused on producing correct answers by using procedures. In particular, the high level tasks were presented at the end of each chapter or unit for wrap up rather than as key resources.

The objective of this study was to identify the effects of the cognitive performance of stroke patients on their motor function recovery after comprehensive rehabilitation management. The subjects of this study were 41 stroke in-patients of the Rehabilitation Hospital, College of Medicine, Yonsei University, hospitalized during the period from September 1, 1997 to May 5, 1998. The cognitive performance was measured using a Mini-Mental State Examination(MMSE) and the motor function recovery using Motor Assessment Scale(MAS). The data were analyzed by the paired t-test, independent t-test, a one way ANOVA, and Pearson's correlation coefficiency. The findings were as follows: 1. There was a significant difference found in the motor function recovery level after the comprehensive rehabilitation management. 2. There was no significant difference found in relation to sex, age, cause of stroke, laterality of paralysis and the level of spasticity. However, there was a big difference between pre- and post-treatment regarding the treatment period. 3. In line with the cognitive performance level, there was a significant difference found in the motor function recovery level after the comprehensive rehabilitation management. 4. The correlation between the elements of the cognitive performance and the motor recovery was found to be high in orientation, attention, calculation, and language. Those elements were expected to give larger effects on motor recovery after the comprehensive rehabilitation management. Based on this study, the cognitive performance level was found to play an important role in bringing effects on motor recovery after the comprehensive rehabilitation management of stroke patients. And the evaluation on the motor recovery based on quality would be also expected to be examined, as well as the cognitive performance level test accompanied by Intelligence Quality(IQ) test.

이 연구에서는 중학교 '과학2' 교과서에 서술되어 있는 '원소', '주기율표', '원자'에 대한 내용이 요구하는 인지 요구도를 분석하였다. 우리나라는 2007년 개정 교육과정에 의하여 처음으로 주기율표 및 그와 관련 내용들을 중학교에서 다루게 되어있다. 분석에 활용한 6종 과학 교과서에 서술된 내용이 어떠한 인지 수준을 요구하는 지를 알아내는 분석틀은 영국에서 개발된 CAT(Curriculum Analysis Taxonomy)의 3종류 분석틀을 사용하였다. 이 3종류 분석틀에 의하여 분석한 '과학2' 교과서에 서술된 내용이 요구하는 인지 수준들은 다음과 같았다. '원소'에 대한 교과서 서술이 더 이상 간단한 물질로 분리될 수 없는 순물질임을 이해하는 내용으로 후기 형식적 조작 수준이었다. 그러나 '원소'는 한 가지 종류의 원자만으로 이루어진 물질이라고 서술된 초기 형식적 조작 수준도 있었다. '주기율표'에 대한 교과서 서술이 다양한 종류의 원소들을 원소 기호를 이용하여 특정 기준에 따라 몇 가지 그룹으로 분류될 수 있음을 이해해야 하고, 실체를 범주화하는데 있어서 여러 기준으로 분류해야 하는 내용으로 후기 구체적 조작 수준이었다. '주기율표'를 여러 족들의 집함임을 알고 이원 분류표로 이해해야 하는 내용으로 초기 형식적 조작수준이었다. '원자' 구조와 연결 짓는 복합적 분류 체계로 주기율표를 표현하는 후기 형식적 수준도 있었다. '원자'에 대한 교과서 서술이 원자가 구조를 가진다는 것 그리고 원자가 같은 종류도 있고 다른 종류도 있다는 서술은 초기 형식적 수준이었다.

Purpose: This study was conducted to analyze the factors that influence the life satisfaction of the elderly according to their cognitive impairment level. Methods: This study was conducted by dividing 3,012 elderly residents of a regional community into three groups based on the scores of the Korean version of the Mini-Mental State Examination: a normal group without any cognitive impairment, a suspicious group with a mild level of cognitive impairment, and a high risk group with a high level of cognitive impairment. Researchers made phone calls, house calls, and personal visits to health centers and shelters for the elderly to gather the information required for this study. Results: The results of this study revealed that social relationships, depression, and activities of daily living had a significant impact on life satisfaction for the normal group, while social relationships and depression had a high impact on life satisfaction for the suspicious group, and social relationships had high impact on the life satisfaction of the high risk group. Conclusion: Based on the results of this study, we suggest that programs that promote development of the social relationship networks of the elderly should be established to promote their life satisfaction.

Purpose: The aim of this study was to identify the participation rate of the National Health Screening Program (NHSP) and its influencing factors by cognitive function level in Korean older adults. Methods: This study was a secondary analysis using data from the survey of the Korean Longitudinal Study of Aging in 2016. The data were analyzed using 𝑥² test and multiple logistic regression. Results: The participation rates of the NHSP in the mild cognitive impairment group (79.6%) and the suspected dementia group (58.0%) were lower than the normal cognitive function group (88.1%). The factors influencing NHSP varied by cognitive function level. Especially, in the suspected dementia group, higher participation rates of the NHSP were associated with living in rural areas, enrollment in private health insurance, no depressive symptoms, participation in social activities, and no living with children. Depression and participation in social activities influenced participation in NHSP in all groups. Conclusion: This study suggests that interventions differentiated by cognitive function level are important for increasing the participation in the health screening.

과학교육에서 개념학습이 중요한 위치를 차지히는 만큼, 개념변화에서 인지갈등의 역할은 크다. 그러나 과학교육 연구에서 인지갈등을 유발하는 방법이 과연 얼마나 효과적인지 다수의 인원으로 검증한 연구가 많지 많으며, 같은 상황임에도 학생에 따라 인지갈등과 개념변화의 정도가 다른 원인에 대한 연구도 찾아보기 어렵다. 본 연구는 이러한 의문을 해결하여 인지갈등을 올바로 이해하고, 앞으로의 개념변화 학습에 보다 효과적으로 활용하고자 인지갈등과 개념변화에 미치는 학습자 특성에 따른 차이를 알아보았다. 연구 대상은 대도시, 중소도시, 읍지역의 777명 남녀 중학생이며, 학습자 특성이란 과학 개념학습과 인지갈등 관련 문헌의 고찰과 과학교육 전문가 대상의 설문 조사를 통하여 대표적인 6가지 학습 변인으로서 지능, 인지수준, 성적, 인지양식, 성격, 과학에 관련된 태도등이다. 연구 결과, 인지갈등 전략에 의한 개념변화에서, 인지갈등의 정도는 성격과 태도 등 정의적 영역과 관계 있으며, 과학적 개념으로의 변화는 지능, 성적 등 지적 영역과 관계 있었다.

Purpose : This study aimed to investigate a study on the intervention of computerized cognitive rehabilitation applied to patients with dementia in Korea. Thus, a systematic discussion was conducted. Methods : Studies from January 2000 to December 2016 were searched in the Korea Education and Research Information Service. The main key words used were: "dementia," "computerized cognitive rehabilitation," "computerized cognitive training," "computer assisted cognitive therapy," and "computerized cognitive therapy." Result : A total of five studies were selected. The effects of the computerized cognitive rehabilitation therapy applied to patients with dementia resulted in improved cognitive functions, as well as daily living and activities instrumental to daily living. There was also an increase in brain activity. The qualitative aspects of this study showed a low level of internal and external validities due to the small number of subjects, short period of intervention, and limited study environment. Conclusion : In the future, it is necessary to continue a study in which the level of evidence is high to determine whether various cognitive rehabilitation programs are effectively applied to patients with dementia.

The purpose of this study is to analyze whether the required cognitive levels of the current 6th graders' science textbooks conform to the children's cognitive levels and to examine the students' sensed psychological difficulty of the current science textbooks. The eighty five students (boy: 39, girl: 46) from one elementary school were participated in this study. The results of the study are as follows. First, the 2/3 out of the contents in the six graders' science textbooks require concrete level of operation and the 1/3 out of the contents in the textbooks requires the formal level of operation. So the 70% students at the concrete operational level are likely to undergo difficulties with the 1/3 contents in the textbooks. Second, the students' psychological difficulty on the science textbooks is relatively low (approximately two out of five points) and there is not any special pattern between the cognitive level of the textbooks and the students' psychological difficulty of the textbooks.

Purpose: This study aims to examine the influence of vitamin D and calcium on depression and cognitive function of the elderly living alone in a city. Methods: The participants were registered in eight senior centers in S city and they had lived alone. Data were collected between November 28, 2014 and March 7, 2015. A total of 155 people participated in data collection to measure the serum vitamin D, the serum calcium, depression, and cognitive function. The data were analyzed with t-test, ANOVA, Pearson's correlation and multiple regression analysis. Results: There were significant differences in depression according to gender and perceptions of health status. Depression correlated significantly with the serum calcium and perceptions of health status, and a stepwise regression analysis showed that the perceptions of health status were significant. There were significant differences in cognitive function according to education level and age. Cognitive function correlated significantly with the serum vitamin D and a stepwise regression analysis showed that education level and age were significant. Conclusion: Consequently, elderly people with poor perceptions of their health status need a depressive intervention program and those with a higher age and lower level of education need a cognitive function intervention program.

Purpose: This study aimed to investigate the job stress level of call center workers and figure out its relation with cognitive emotion regulation strategies as a cognitive coping strategy. Methods: Data collection was conducted on 985 call center workers, working for K companies in Korea. ANOVA, t-test, Scheffe's test and multiple regression have been conducted for the data analysis using SAS 9.0 software. Results: The total job stress score of subjects ranges $Q_{25{\sim}49}$ (the lower 50%) whereas the score of job demand and job control ranges $Q_{50{\sim}74}$ (the upper 50%), and its sectional job stress level is high. Since job stress is the major factor affecting cognitive emotion regulation strategies, it is shown that when the job stress score gets higher, the score of positive cognitive emotion regulation strategies gets decreased but the score of negative cognitive emotion regulation strategies, increased. Conclusion: Based on the results of this study, it is necessary to develop and apply an effective stress easing method for call center workers which reduces negative cognitive emotion regulation strategies and increases positive ones.
